RESUMEN
Objective: To analyze and summarize the clinical and pathological characteristics, management, and efficacy of patients with vulvar lichen sclerosus (VLS) through a single center large sample study, and preliminarily to explore the frequency of maintenance treatment medication for VLS. Methods: The clinical data of VLS patients in Obstetrics and Gynecology Hospital of Fudan University from 2018 to 2021 were retrospectively collected. The clinicopathological characteristics (patients' age, course of disease, complicated disease history, family history, symptoms, signs and pathology), treatment and effects were retrospectively analyzed. The patients in the maintenance treatment stage were followed up regularly to explore the minimum frequency of individual medication to maintain the stability of the disease. Results: (1) General situation: a total of 345 patients with VLS were included in this study. The average age was (50.4±14.7) years (ranged from 8 to 84 years old), prevalence was highest in the 50-59 years group (30.1%, 104/345). Immune diseases occurred in 18.6% (33/177) of patients, 24.3% (43/177) of patients had allergic skin diseases, and 5.6% (10/177) of the patients' immediate family members had chronic vulvar pruritus or vulvar hypopigmentation. (2) Clinical features: the most common symptom was vulvar pruritus (96.1%, 196/204) among 204 patients with recorded symptoms. The most common sign was hypopigmentation of the vulva (96.3%, 206/214). The most common involved sites were labia minora (70.3%, 142/202), labia majora (67.8%, 137/202), and labial sulcus (59.4%, 120/202). The cumulative number of sites involved in 62 vulvar atrophy patients (2.7±1.1) was significantly higher than that in 152 non-atrophy patients (2.2±1.0; t=3.48, P=0.001). The course of vulvar atrophy was (9.3±8.5) years, which was significantly longer than that of non-atrophy patients [(6.6±5.6) years; t=2.04, P=0.046]. (3) Pathological features: among the 286 patients with electronic pathological sections, the most common pathological feature in the epidermis was epithelial nail process passivation (71.3%, 204/286). The common pathological features in the dermis were interstitial collagenization (84.6%, 242/286), and inflammatory cell infiltration (73.8%, 211/286). (4) Treatment: 177 patients received standardized treatment after diagnosis and were followed up regularly in our hospital. In the initial treatment stage, 26.0% (46/177) of the patients were treated with 0.05% clobetasol propionate cream, and 74.0% (131/177) of the patients were treated with 0.1% mometasone furoate ointment. The complete remission rates of the two methods were respectively 80.4% (37/46) and 74.0% (97/131), and there was no statistically significant difference (χ²=0.76, P=0.385). During maintenance treatment, 27.1% (48/177) of the patients took the medication twice a week, 35.0% (62/177) took the medication once a week, and 37.9% (67/177) took the medication once every 10 days. During follow-up after 6 months of maintenance treatment, there were no patients with recurrence of pruritus or progression of vulvar signs. Conclusions: The majority of VLS patients have itching, hypopigmentation, involvement of labia minora and labia majora, progressive atrophy, and inflammatory infiltration of dermis. Local treatments of mometasone furoate and clobetasol propionate have good initial therapeutic effects. The frequency exploration of individualized maintenance treatment could minimize the occurrence of adverse reactions when ensuring the stability of the patients' condition.

Objective: To analyze and summarize the oncological outcomes after laparoscopic radical trachelectomy (LRT) for early stage cervical cancer. Methods: The clinical data and follow-up results of 148 patients with early stage cervical cancer who underwent LRT in Renji Hospital, School of Medicine, Shanghai Jiao Tong University from July 2014 to June 2023 were collected, while tumor outcomes and postoperative pregnancy were analyzed retrospectively. Results: (1) General situation: the median age of 148 patients with LRT was 33 years (range: 19-42 years). Pathological type: 111 cases of squamous cell carcinoma, 36 cases of adenocarcinoma, 1 case of adenosquamous carcinoma. International Federation of Gynecology and Obstetrics (2018) stage: 17 cases of stage â a1 with lympho-vascular space invasion, 25 cases of stage â a2, 102 cases of stage â b1, and 4 cases of stage â b2. (2) Tumor outcomes: 148 patients were followed up regularly after LRT, and the median follow-up time was 59 months (range: 2-104 months). During the follow-up period, 5 cases of tumor recurred (including 1 death), and the median recurrence time was 10 months (range: 4-33 months). Among them, there were 3 cases of pelvic metastasis, 1 case of distant metastasis, and 1 case of both pelvic and distant metastasis. Both 3-year and 5-year disease-free survival rates of 148 patients were 94.5%, and the 5-year overall survival rate was 98.9%. (3) Postoperative pregnancy: among 148 patients with LRT, 67 patients had pregnancy requirements, followed up for 1 year, and 20 of them were pregnant, with a pregnancy rate of 29.9% (20/67). Among the 20 pregnant patients, 2 cases early abortion, 1 case mid-term abortion, and 17 cases gave birth (including 4 cases of premature birth and 13 cases of full-term birth). Conclusion: Under the condition of strict control of surgical indications, guaranteed surgical scope and tumor-free operation, LRT in patients with early cervical cancer has a good outcome.

Objective: To understand the status of tuberculosis diagnosis and treatment capacity and the development and changes of tuberculosis diagnosis and treatment in provincial and municipal designated medical institutions in China from 2017 to 2022, so as to provide a basis for the formulation of relevant policies for the improvement and development of designated medical institutions for tuberculosis and the tuberculosis prevention and treatment service system, and to provide reasonable support for further strengthening the capacity of designated medical institutions for tuberculosis. Methods: This study was initiated and carried out by Beijing Chest Hospital affiliated to Capital Medical University/Clinical Center for Tuberculosis Prevention and Control of China CDC (hereinafter referred to as "Clinical Center") by means of questionnaire survey, and the investigation was carried out from March to November 2023. During this period, the clinical center distributed questionnaires to the hospital member units of "Beijing Tuberculosis Diagnosis and Treatment Technology Innovation Alliance", retrospectively collected their tuberculosis-related diagnosis and treatment data from 2017 to 2022, and used descriptive statistical methods to analyze the number of tuberculosis beds, outpatients and hospitalizations in medical institutions. The results were expressed in absolute numbers (percentages), and three-line tables, bar charts and line charts were drawn to describe the analysis results and changing trends. Results: The 54 medical institutions surveyed in this survey included 21 provincial-level designated medical institutions and 33 prefecture-level designated medical institutions. Most medical institutions have set up clinical departments, auxiliary departments and functional departments to undertake public health tasks of infectious diseases. The tuberculosis laboratory in the hospital has a comprehensive ability and has the detection technology needed for most tuberculosis diagnosis; The number of tuberculosis beds, children's tuberculosis beds and ICU beds all showed an increasing trend from 2017 to 2022. The proportion of tuberculosis beds in the hospital decreased slightly, from 39.31% in 2017 to 34.76% in 2022, showing a slight downward trend. Compared with the hospital surveyed, the number of tuberculosis outpatients in 2019 was 562 029, and the number of outpatients in 2020-2022 was 462 328, 519 630 and 424 069 respectively, which was significantly lower than that in 2019. The number of tuberculosis outpatients in medical institutions decreased significantly from 2020 to 2022. By analyzing the proportion of patients with different types of tuberculosis, the proportion of sensitive tuberculosis outpatients in 2017-2022 decreased from 84.49% in 2017 to 78.05% in 2022, showing a downward trend year by year. The proportion of patients with multidrug-resistant/ rifampin-resistant tuberculosis increased from 2.03% in 2017 to 7.18% in 2022. From 2017 to 2019, the total number of inpatients with tuberculosis showed an upward trend. Compared with 2019, the number of inpatients in 2020, 2021 and 2022 showed a downward trend, and the decline in 2020 was large (down 14.94% compared with 2019). Among the inpatients, the absolute number and proportion of patients with sensitive pulmonary tuberculosis remained relatively stable, and the number and proportion of inpatients with multidrug-resistant/rifampin-resistant pulmonary tuberculosis increased year by year. Conclusions: Most medical institutions have the capacity to carry out routine diagnosis and treatment of tuberculosis, but the public health function needs to be strengthened. The transformation of medical institutions requires proper guidance and adequate support. During 2019-2022, most medical institutions were affected by the COVID-19 epidemic, and their tuberculosis diagnosis and treatment work also changed to varying degrees. During this period, hospitals took various measures to overcome difficulties and tried their best to maintain the normal development of tuberculosis diagnosis and treatment, and the tuberculosis diagnosis and treatment work of various institutions gradually resumed in 2022.

Objective: To investigate the incidence, risk factors, and outcomes of hyperlactatemia after pulmonary endarterectomy (PEA) under deep hypothermic circulatory arrest (DHCA). Methods: From December 2016 to January 2022, patients receiving PEA in China-Japan Friendship Hospital were enrolled in the study. Arterial blood samples were analyzed intraoperatively. Multivariate logistic regression analysis was performed to identify the predictors of intraoperative lactate elevation as well as major factors influencing the clinical outcome of the surgery. Results: A total of 110 patients (69 males and 41 females) were enrolled, aged (50.6±12.8) years. Receiver operating characteristic curve yielded an optimal cut-off lactate level of 7 mmol/L for predicting major postoperative complications (re-operation, re-intubation, postoperative renal failure requiring renal replacement therapy, wound infection, stroke, atrial fibrillation, and perioperative extracorporeal membrane oxygenation usage within 48 hours after surgery). Thirty-nine patients (35.5%) had an intraoperative peak arterial lactate level of≥7 mmol/L. According to intraoperative peak arterial lactate level, the patients were divided into two groups (<7 mmol/L and≥7 mmol/L). There were no statistically significant differences in age, sex and body mass index between the two groups (all P>0.05). Intraoperative peak lactate level was associated with prolonged mechanical ventilation time (r=0.262, P=0.008) and intensive care unit length of stay (r=0.304, P=0.002). Multivariate logistic regression analysis identified three key variables associated with lactate level≥7 mmol/L: DHCA duration (OR=1.186, 95%CI: 1.027-1.370, P=0.020), nadir hematocrit (HCT) (OR=0.580, 95%CI: 0.341-0.988, P=0.045) and preoperative pulmonary vascular resistance (PVR) (OR=1.096, 95%CI: 1.020-1.177, P=0.012). Patients with lactate≥7 mmol/L carried a higher rate of major complications (P=0.001). For patients with lactate≥7 mmol/L, 41.0% (16 out of 39 cases) had major complications, while for patients with lactate<7 mmol/L, only 14.1% (10 out of 71) had major complications. There was no statistically significant difference in mortality (8.5% vs 10.3%, P=0.753) between patients with different lactate levels. Moreover, intraoperative peak lactate level was a predictor of postoperative combined morbidity (OR=1.625, 95%CI: 1.176-2.245, P=0.003). Conclusion: High intraoperative lactate levels are associated with higher preoperative PVR, lower nadir HCT, and longer DHCA duration. Intraoperative lactate levels are independently associated with increased combined morbidity.

This study takes Cushing's syndrome, a rare disease, as a model, and adopts the path of "Plan, Do, Check, Action" (PDCA) to explore new methods to optimize the clinical path, can improve the quality and efficiency of diagnosis and treatment of rare diseases. After sorting out the problems existing in the previous diagnosis and treatment mode, our team optimizes the path in various ways and establishes a standard operation procedure (SOP) for the new path. In the evaluation of the optimized mode, 55 patients with Cushing's syndrome were admitted to the Department of Endocrinology, Peking Union Medical College Hospital, including 19 males and 36 females, aged (41.8±14.4) years (6-68 years). The pathway group (28 cases) and the control group (27 cases) were divided according to whether they were included in the new path management at the time of admission, and the effect of path optimization was assessed in terms of time, efficacy, safety and cost. The results showed that compared with the control group, the pathway group had a shorter time of hospitalization in the Department of Endocrinology and critical tests, such as blood cortisol rhythm, low-dose dexamethasone inhibition test, and bilateral inferior petrosal sinus sampling (all P<0.05). There was no significant differences in the decrease of total cortisol after operation, the incidence of postoperative complications, and hospitalization expenses (all P>0.05). The optimized path improves the medical efficiency while ensuring medical quality, safety and no increase in cost. This study proposes PDCA path optimization for complex diseases and establishes SOP process, which provides experience in management optimization for the patient-centered and clinical path-oriented diagnosis and treatment mode of rare diseases.

Objective: To evaluate the clinical safety and efficacy of toric intraocular lens (IOL) implantation for more than 5 years. Methods: This study was a prospective cohort study in which subjects were continuously observed over a two-year period (May 2014 to May 2016) in nine hospitals. The study randomly assigned subjects to two groups using a central dynamic randomization system: the study group, which received Proming® IQ toric IOL implants, and the control group, which received AcrySof® IQ toric IOL implants. The subjects completed a one-year follow-up, during which various measures were taken and evaluated, including visual acuity, IOL rotation, postoperative complications, intraocular pressure, and subjective evaluation (preoperatively and at 1 day, 6 months, 1 year, and 5 years post-surgery). The main statistical analysis methods include the Mann-Whitney U test, independent sample t-test, Wilcoxon signed rank test, paired sample t-test, chi-square test, and Fisher's exact test. Results: A total of 45 eyes (26 in the study group and 19 in the control group) completed the five-year continuous observation period. The mean age of the subjects was (72.07±10.67) years and the mean interval from surgery to the last visit was (5.39±0.47) years. After five years, there were no significant differences in uncorrected distance visual acuity (0.20±0.26 vs. 0.16±0.13, t=0.17,P=0.752), best corrected distance visual acuity[0.00(0.00, 0.20) vs. 0.05±0.10, U=188.00, P=0.880], uncorrected near visual acuity[0.50 (0.20, 0.60) vs. 0.42±0.20, t=0.35, P=0.857], and best corrected near visual acuity (0.13±0.16 vs. 0.17±0.23, U=161.00, P=0.884) between the two groups. However, all measures improved significantly from baseline levels in both groups (all P<0.05). Five years after surgery, no matter objective refraction [(-0.67±0.85) D vs. (-0.73±1.08)D] or subjective refraction[-0.50 (-1.00, 0.00)D vs. (0.69±0.87)D], the degree of cylindrical degree is significantly lower than preoperative corneal astigmatism [(1.27±0.49) D vs. (1.34±0.82) D, all P<0.001]. In addition, there were no significant differences in intraocular pressure, subjective evaluation of visual adverse symptoms, distance vision spectacle independence, or overall satisfaction evaluation between the two groups (all P>0.05). The IOL rotation was 3.0°(1.0°, 6.0°) in the study group and 4.0°(2.0°, 6.0°)in the control group (U=185.50,P=0.574), indicating no significant difference between the groups in terms of rotational stability. Five years after surgery, there were 7 cases of posterior capsular opacification in the study group and 4 cases in the control group. There were no cases of IOL glistening in the study group, but 5 cases (26.32%) were observed in the control group. Conclusions: The long-term effects of Proming® toric IOL implantation in correcting cataracts with regular corneal astigmatism are clear after five years, with few complications and stable results.

OBJECTIVE: To describe the distribution characteristics of inflammatory bowel disease among permanent residents in Yinzhou District, Ningbo City, and to understand the disease burden and development trend of inflammatory bowel disease in this area. METHODS: Using the retrospective cohort design, we collected the registration information of all permanent residents in the residents' health files of the Yinzhou Regional Health Information Platform from 2010 to 2020, and used electronic medical records to follow up their inflammatory bowel disease visits. A one-year wash-out period was set, and the patients who were diagnosed with the primary diagnosis for the first time after one year of registration were re-garded as new cases. The incidence density and 95% confidence interval (CI) of inflammatory bowel disease were estimated by Poisson distribution. RESULTS: From 2011 to 2020, a total of 1 496 427 permanent residents in Yinzhou District were included, of which 729 996 were male (48.78%). The total follow-up person-years were 8 081 030.82, and the median follow-up person-years were 5.41 [interquartile range (IQR): 5.29]. During the study period, there were 1 217 new cases of inflammatory bowel disease, of which males (624 cases, 51.27%) were more than females (593 cases, 48.73%). The total incidence density was 15.06/100 000 person-years (95%CI: 14.23, 15.93). Among all new cases, there were 1 106 cases (90.88%) of ulcerative colitis, with an incidence density of 13.69 per 100 000 person-years (95%CI: 12.89, 14.52); 70 cases (5.75%) of Crohn's disease, with an incidence density of 0.87 per 100 000 person-years (95%CI: 0.68, 1.09); and 41 cases (3.37%) of indeterminate colitis, with an incidence density of 0.51 per 100 000 person-years (95%CI: 0.36, 0.69). The median age of onset of ulcerative colitis was 50.82 years old (IQR: 18.77), with the highest proportion (15.01%) in the 45-49 years group. The incidence density of ulcerative colitis gradually increased with age, reaching a relatively high level in the 45-49 years group (20.53/100 000 person-years; 95%CI: 17.63, 23.78), followed by a slight increase. And the incidence density in the 65-69 years group was the highest (25.44/100 000 person-years; 95%CI: 20.85, 30.75), with a rapid decrease in the 75-79 years group. The median age of onset of Crohn's disease was 44.34 years (IQR: 33.41), with the highest proportion (12.86%) in the 25-29 years group. Due to the small number of new cases of Crohn's disease, the age distribution fluctuated greatly, with peaks both in young and old people. From 2011 to 2020, the incidence density of inflammatory bowel disease in Yinzhou District was at a low level from 2011 to 2013, and showed a rapid upward trend from 2014 to 2016, reaching a peak of 24.62 per 100 000 person-years in 2016 (95%CI: 21.31, 28.30), and slightly decreased in 2017-2020. CONCLUSION: The incidence density of inflammatory bowel disease in Yinzhou District from 2011 to 2020 was at a relatively high level, and medical institutions and health departments need to pay attention to the burden of disease caused by it.

Objective: To describe the clinical characteristics of sarcoidosis patients with arrhythmia as the primary or main manifestation. Methods: We conducted a retrospective analysis of arrhythmia-onset sarcoidosis cases between January 2017 and December 2020. Their clinical manifestations, radiological features, treatment and prognosis were reviewed and analyzed. Results: This study consisted of 3 females and 1 male, with a mean age of 51 years (range from 42 to 58 years old). Arrhythmia was the first or main clinical manifestation for all 4 cases, involving â ¢° atrioventricular block (AVB) (n=1), â ¡° type â ¡ AVB (n=1), and frequent ventricular premature beats and short array ventricular tachycardia (n=2). Three cases were diagnosed with respiratory sarcoidosis simultaneously during the diagnostic evaluation for arrhythmia. One case was diagnosed with sarcoidosis because of abnormal chest CT images due to cervical lymph node enlargement 5 years after arrhythmia. All 4 cases were confirmed as presenting epithelioid cell granulomatous inflammation by bronchoscopic biopsies. Late gadolinium enhancement with cardiac magnetic resonance (LGE-CMR) imaging was arranged for two cases. Both of them had typical imaging findings of cardiac sarcoidosis. Three cases were confirmed of cardiac involvement through positron emission computed tomography (PET)-CT. None of the enrolled four cases were arranged with endomyocardial biopsy. All four cases were improved with oral corticosteroids, immunosuppressants and anti-arrhythmic medications. Two cases underwent cardiac pacemaker implantation. Conclusions: The possibility of cardiac sarcoidosis should be considered in middle-aged and elderly patients with unexplained high-degree AVB or ventricular arrhythmia. Chest CT is recommended for routine screening for those cases. LGE-CMR and/or PET-CT is recommended for them to confirm the diagnosis of cardiac sarcoidosis. Corticosteroids and immunosuppressants are effective for these patients.

Objectives: To describe the underlying diseases, microbiologic examination and severity of hospitalized patients with Pneumocystis jirovecii pneumonia (PJP) in a tertiary Chinese hospital. Methods: We conducted a retrospective analysis of 485 identified PJP patients who were admitted to our hospital between January 2013 and December 2021. Results: Among the 485 enrolled PJP cases, there were 237 males and 248 females, aging (53.3±16.2) years (range from 14 y to 88 y). They were divided into 8 subgroups with variable underlying diseases. There were 209 cases with connective tissue diseases(CTD), 27 cases with non-hematologic malignancies, 38 cases with hematologic malignancies, 81 cases with kidney diseases, 33 cases with idiopathic interstitial pneumonia(IIP), 30 cases infected with human immunodeficiency virus (HIV), and 42 cases with miscellaneous underlying diseases. In the CTD group, there was more females than males, while male patients were predominant in both the malignant and the HIV groups. The Pneumocystis was identified in 44.95%(218/485) sputum samples and 92.01%(265/288) bronchoscopic samples. Pneumocystis asci were observed at direct microscopic examination with Grocott's methenamine silver stain in 4.95%(24/485)sputum samples and 9.72%(28/288)bronchoscopic samples. Pneumocystis DNA fragments were identified by PCR analysis in 43.09%(209/485)sputum samples and 90.63%(261/288)bronchoscopic samples. Among the 8 groups, cytomegaviremia and respiratory failure were most common in the HIV-infected PJP group, but the rates of mechanic ventilation, intensive care unit (ICU) admission and death were the lowest. There were less PJP patients in the IIP group (IIP-PJP) who received mechanic ventilation and admitted to ICU than the other groups except HIV-infected PJP group. However, the mortality rate was highest for the IIP-PJP group. Conclusions: CTD was the most common predisposed underlying disease for our enrolled PJP cases. Cytomegaviremia and respiratory failure were common in HIV-infected PJP patients, but the prognosis of HIV-PJP was slightly better than the others. The disease was more severe, rapidly progressive and fatal in the IIP-PJP group.

Objective: To explore the incidence and risk factors of cardiovascular events in hematological neoplasms patients treated with anthracyclines in the real world. Methods: A total of 408 patients with lymphoma and leukemia, who were treated with anthracyclines during hospitalization in the First Affiliated Hospital of Dalian Medical University from January 1, 2018 to July 31, 2021, were included in this retrospective study. Patients were divided into cardiovascular event group (n=74) and non-cardiovascular event group (n=334). The primary endpoint was cardiovascular events (arrhythmia, heart failure, acute myocardial infarction etc.) after anthracyclines therapy. The secondary endpoint was all-cause mortality, cardiovascular-cause death, discontinued chemotherapy due to cardiovascular events. Multivariate regression analysis was used to investigate the risk factors of cardiovascular events. Kaplan-Meier was performed to calculate the incidence of all-cause mortality. Results: The mean age was (55.6±14.9) years, and there were 227 male patients (55.6%) in this cohort. The median follow-up time was 45 months. During follow-up, cardiovascular adverse events occurred in 74 patients (18.1%), including 45 heart failure (38 were heart failure with preserved ejection fraction), 30 arrhythmia, 4 acute myocardial infarction and 2 myocarditis/pericarditis. Multivariate regression analysis showed age (OR=1.024, 95%CI 1.003-1.045, P=0.027) and history of hypertension over 10 years (OR=2.328, 95%CI 1.055-5.134, P=0.036) were independent risk factors for the cardiovascular events. Kaplan-Meier survival curve showed mortality was significantly higher in cardiovascular event group than in non-cardiovascular event group (47.3% vs. 26.6%, P=0.001). In the cardiovascular event group, chemotherapy was discontinued in 9 cases (12.2%) due to cardiovascular events and cardiovascular death occurred in 7 cases (9.5%). Conclusions: Although heart failure is the main cardiovascular event in lymphoma and leukemia patients post anthracyclines therapy, other cardiovascular events especially arrhythmias are also common. The presence of cardiovascular events is associated with higher risk of all-cause mortality in these patients. Age and long-term hypertension are independent risk factors for cardiovascular events in lymphoma and leukemia patients after anthracyclines treatment.

Objective: To investigate the relationship between clinical characteristics of patients with chronic obstructive pulmonary disease (COPD) with pulmonary hypertension (PH) and COPD exacerbation over a three-year observation period. Methods: A total of 366 cases of stable COPD patients were enrolled from the Department of Respiratory Medicine of the First Affiliated Hospital of Henan University of Science and Technology. The patients underwent pulmonary function tests(PFT), COPD assessment test (CAT), Saint George's respiratory questionnaire (SGRQ), transthoracic echocardiogrophy(TTE), chest CT and biochemical detection. The likelihood of PH was evaluated based on the peak tricuspid regurgitation velocity (TRV) measured by echocardiography at rest and other indicators, which were represented by low, medium, and high probability, respectively. Highly probability was defined as PH. The mean values of the groups were compared using a two-tailed unpaired t test for normally distributed variables. Qualitative data were assessed using a χ2 test. Pearson correlation analysis was performed, and risk factors were analyzed using logistic regression analysis and stepwise regression analysis. P<0.05 was considered to indicate statistical significance. Results: The prevalence of patients with high likelihood of PH was 18.3% (n=67) in a series of 366 patients with COPD. The median estimated systolic pulmonary artery pressure in patients with PH was (51.7±6.7) mmHg(1mmHg=0.133 kPa). There were differences between patients with high likelihood of PH and those with low to moderate likelihood of PH for the following factors: age (76.0 vs. 64.0), body mass index (BMI) [(21.4±6.0) kg/m2 vs. (22.6±7.2)kg/m2], brain natriureticpeptide (BNP) [(50.8±9.1) pg/ml vs. (36.4±8.1) pg/ml], toral number of acute exacerbation in three-year [(6.1±0.1) times vs. (2.8±0.4) times], CAT (17.0 vs. 10.0), SGRQ (48.9 vs. 32.1), carbon monoxide diffusion percentage of predicted value (DLCO%) [(51.9±21.9)% vs. (67.0±22.1)%]; all the differences being statistically significant(mean P<0.05).There was a negative correlation between DLCO% and SPAP (r=-0.28, P<0.01).In patients with high likelihood of PH, the percentage of low attenuation area (LAA%) and interstitial abnormalities in chest CT were higher than those in patients with low to moderate likelihood of PH (56.1% vs. 34.3% and 30.8% vs. 15.6%, mean P<0.05).LAA% ≥ 30% and pulmonary interstitial abnormalities were independent risk factors for pH [beta value were 1.479, 1.065, OR value was (3.640-5.720), 95%CI (1.462-8.571), mean P<0.01]. The ratio of main pulmonary diameter to aortic artery diameter was significantly correlated with estimated systolic pulmonary artery pressure(r=-0.35, P<0.01).Age ≥75 years, FEV1%predicted value<50% and the presence of PH increased the likelihood of exacerbations of COPD over three years[beta value (0.459-1.211), OR value (3.643-5.722), 95%CI (1.463-8.904), mean P<0.01]. Conclusions: COPD patients with high likelihood of PH assessed by echocardiography were older, had a lower BMI, and presented with a worse health status compared to those with low to moderate likelihood of PH. The presence of PH assessed by echocardiography was related to future COPD exacerbations in COPD patients, and emphysema was closely related to PH assessed by echocardiography.

Objective: To evaluate the clinical safety and efficacy of A1-UV aspheric intraocular lens (IOL) implantation over the postoperative 5 years. Methods: Prospective cohort study. The subjects came from a finished multicenter, randomized and controlled clinical trial with a follow-up period of 1 year from April to November 2012. The clinical research centers were Beijing Tongren Eye Center, Beijing Tongren Hospital, Capital Medical University, Peking University Third Hospital, Tianjin Medical University Eye Hospital, and Daping Hospital of Army Medical University. Cataract patients in the experimental group were implanted with A1-UV type IOL, while cataract patients in the control group were implanted with SN60WF type IOL, and monocular patients were enrolled. From April to May 2018, patients enrolled in the previous study were recalled for follow-up and continued observation. The visual acuity, spherical equivalent, postoperative complications, non-contact intraocular pressure and subjective evaluation results were statistically analyzed preoperatively, at 1 to 2 days, 1 week, 1 month, 3 months, 6 months, 1 year and 5 years after operation. The main statistical methods included Mann Whitney U test, Wilcoxon signed rank test, independent sample t test, chi square test and Fisher exact test. Results: A total of 42 subjects (22 in the experimental group and 20 in the control group) completed 5-year continuous observation. Among the 42 subjects, 28 were female and 14 were male. The age was (70±9) years, and the time from surgery to recall was (5.77±0.19) years. The age, gender distribution, left/right eye distribution, axial length, IOL power and nucleus hardness classification data of the experimental group and the control group were balanced and comparable (all P>0.05). At different visiting time points, there was no significant difference in the best corrected distance visual acuity (BCDVA), best corrected near visual acuity (BCNVA), uncorrected distance visual acuity (UCDVA) and uncorrected near visual acuity (UCNVA) between the groups (all P>0.05). At 5 years after operation, the UCDVA, BCDVA and BCNVA of the two groups were significantly improved compared with the baseline [all P<0.01; UCDVA was improved from 0.75 (0.30 to 1.30) to 0.10 (-0.10 to 0.70) in the experimental group and from 0.75 (0.30 to 1.60) to 0.20 (-0.10 to 0.80) in the control group; BCDVA was from 0.60 (0.10 to 1.00) to 0.00 (-0.10 to 0.54) in the experimental group and from 0.60 (0.10 to 1.60) to 0.10 (-0.10 to 0.50) in the control group; BCNVA was from 0.55 (0.00 to 1.10) to 0.10 (-0.10 to 0.60) in the experimental group and from 0.55 (0.10 to 1.60) to 0.10 (-0.20 to 0.60) in the control group], but there was no significant change in the UCNVA (both P>0.05). There were no significant differences in the spherical equivalent, intraocular pressure, subjective evaluation of visual adverse symptoms, distance vision spectacle independence and comprehensive evaluation of satisfaction between the groups (all P>0.05). In the experimental group, one eye (4.5%) had an abnormal pupil, one eye (4.5%) had an abnormal IOL with a few particles on the surface of the IOL but no glistening, and 3 eyes (13.6%) had posterior capsular opacification (PCO); in the control group, one eye (5.0%) had an abnormal cornea, five eyes (25.0%) had abnormal IOLs [one eye (5.0%) had IOL calcification, and four eyes (20.0%) had IOL glistening], and one eye (5.0%) had PCO with posterior capsular folds and IOL tilt. There was no significant difference in PCO and IOL abnormality between the two groups (both P>0.05), but there was significant difference in the occurrence of IOL glistening (P=0.04). Conclusion: The long-term effect of A1-UV aspheric IOL on improving the UCDVA is stable and good, with high subjective satisfaction of patients, a low incidence of PCO, no glistening and good biocompatibility, over the postoperative 5 years.

Objective: To analyze the current status of clinical treatment and factors influencing postoperative mortality in infants with critical congenital heart disease (CCHD) in China, optimize the perioperative management of CCHD, and provide a new scientific basis for clinical decision-making for the optimal management of these patients. Methods: This is a retrospective single-center study. Infants diagnosed with CCHD in Guangdong Provincial People's Hospital from January 2017 to December 2019 (aged 0-1 years at admission) were enrolled. General clinical information, inpatient treatment information, prognosis and complications were collected and analyzed. Multivariate logistic regression analysis was used to explore the independent risk factors of postoperative death in infants with CCHD. Results: A total of 826 infants with CCHD were included, including 556 males (67.3%) and the age at first admission was 51.0 (5.0,178.3) days. 264 (32.0%) cases were tetralogy of Fallot and 137 (16.6%) cases were total anomalous pulmonary venous return. 195 cases (23.6%) were diagnosed prenatally. 196 cases (23.7%) were treated with prostaglandin. The preoperative invasive ventilation time was 0 (0, 0) hour, and the postoperative invasive ventilation time was 95.0 (26.0, 151.8) hours. A total of 668 cases (80.9%) underwent surgical treatment. The age was 100.5 (20.0, 218.0) days during operation and the operation time was 190.0 (155.0, 240.0) hours. Sixty-two cases (7.5%) received medical treatment, and 96 cases (11.6%) gave up treatment. A total of 675 cases (81.7%) were discharged with improvement, 96 cases (11.6%) were discharged after giving up treatment, 55 cases (6.7%) died and 109 cases (13.2%) were readmitted within one year. Complications occurred in 565 (68.6%) cases, including pneumonia in 334 cases (40.4%) and cardiac arrhythmias in 182 cases (22.0%). Multifactorial analysis showed that delayed chest closure (OR=49.775, 95%CI 3.291-752.922, P=0.005), prolonged post-operative invasive ventilator ventilation (OR=1.003, 95%CI 1.000-1.005, P=0.038) and cardiac hypoplasia syndrome (OR=272.658, 95%CI 37.861-1 963.589, P<0.001) were the independent risk factors for mortality in CCHD infants post-operation. Conclusions: Tetralogy of Fallot and total anomalous pulmonary venous return account for the majority of infants with CCHD. The proportion of infants diagnosed prenatally was less than 1/4. The majority CCHD infants received surgical treatment. The main complications are pneumonia and arrhythmia. Delayed chest closure, prolonged postoperative invasive ventilator ventilation and low cardiac output syndrome are the independent risk factors for postoperative death in infants with CCHD.

OBJECTIVE: To systematically review the diagnostic accuracy of Xpert® Mycobacterium tuberculosis/rifampicin (Xpert® MTB/RIF) for the detection of active tuberculosis (TB) and rifampicin-resistance TB in Chinese patients. METHODS: Four Chinese databases (SinoMed, CNKI, WanFang database, and VIP) and three English databases (PubMed, Embase, and The Cochrane Library) were searched from January 1, 2000 to September 15, 2017, to identify diagnostic tests about the accuracy of Xpert® MTB/RIF in Chinese patients. Two investigators screened the articles and extracted the information independently, and then the quality of each included study was evaluated by Quality Assessment of Diagnostic Accuracy Studies (QUADAS)-2. Bivariate random-effects meta-analysis was conducted to pool the sensitivity and specificity. In addition, subgroup analyses were performed based on patient type (TB patient and TB suspected patient), sample type (sputum, bronchoalveolar lavage fluid and others). All statistical analyses were conducted with Stata version 13.0. RESULTS: A total of 47 articles were included in this systematic review. Most of them (38 articles) were in Chinese and only 9 articles were in English. All the articles were published during 2014 to 2017, and the sample size ranged from 31 to 3 151. Forty articles including 42 comparisons about TB were finally included with the pooled sensitivity of 0.94 (95%CI: 0.92, 0.95) and the pooled specificity of 0.87 (95%CI: 0.84, 0.91). Subgroup analysis showed that different patient and specimen types had no significant differences on sensitivity, but the specificity of sputum group was higher than that of bronchoalveolar lavage fluid. As for the detection of rifampicin-resistant TB, 33 articles (38 comparisons) were analyzed, the pooled sensitivity and specificity were 0.92 (95%CI: 0.89, 0.94) and 0.98 (95%CI: 0.97, 0.99) respectively. There were no significant differences between the patient and specimen in the subgroup analyses. The Deeks funnel plot showed a possible publication bias for detecting active tuberculosis (P=0.08) and no publication bias for rifampicin-resistant TB (P=0.24). The likelihood ratio scatter gram showed that in clinical applications, Xpert® MTB/RIF had a good diagnostic ability for detecting active tuberculosis, and it had good clinical diagnostic value in detecting rifampicin-resistant TB. CONCLUSION: Xpert® MTB/RIF has good sensitivity and specificity in detecting TB and rifampicin-resistant TB in Chinese people. In particular, it has good clinical value in diagnosing rifampicin-resistance TB.

Objective: To compare the effect of myotomy and coronary artery bypass grafting (CABG) to treat symptomatic myocardial bridges (MBs) of the left anterior descending artery (LAD). Methods: From January 2009 to December 2017, a total of 54 eligible patients [34 males, 20 females, with a median age of 60 (51, 64) years old] with symptomatic MBs of LAD who underwent myotomy (31 patients) or CABG (23 patients) at the Department of Cardiovascular Surgery of Zhongshan Hospital, Fudan University were included in the study. Surgical effect of the two groups were compared and multivariate logistic regression models were used to analyze the risk factors of major adverse cardiac events (MACE). Results: No significant differences between the two groups were observed with respect to age, gender, risk factors of coronary artery disease (CAD), symptoms, angiographic findings of MBs and preoperative cardiac status, and 0 surgery-associated death was observed. Among the 31 myotomy patients, 4 patients underwent off-pump myotomy (including one patient who underwent urgent conversion from off-pump to on-pump surgery due to massive hemorrhaging secondary to the right ventricular perforation), and the remaining 27 cases received myotomy under cardiopulmonary bypass with cardiac arrest. All 23 bypass surgery patients underwent off-pump CABG surgery with in situ left internal mammary artery (LIMA) grafting to the distal LAD. After LIMA grafting, the median graft flow was 14 (11, 20) ml/min. During a median follow-up of 26 months, 11 patients developed MACEs (7.4% for myotomy vs 40.9% for bypass surgery, P=0.007). Surgical strategy (CABG surgery vs myotomy) was an independent risk factor for MACE (OR=3.681, 95% CI: 1.812-8.685, P=0.011). Compared with myotomy, CABG surgery had a significantly higher incidence of adverse angiographic results (3.7% of residual compression vs 40.9% of LIMA graft failure, P=0.003). Among 10 CABG surgery patients with LAD-MBs and proximal coronary obstruction, all LIMA grafts were patent, though one case reported recurrent angina pectoris 2 years after the surgery which was relieved after drug therapy. Conclusions: For patients with symtomatic LAD-MBs, myotomy may be associated with favorable mid-term outcomes and angiographic results. However, CABG surgery should be recommended for those with concomitant proximal obstruction of LAD.

Objectives: To describe the clinical features and prognosis of pulmonary actinomycosis in a tertiary Chinese hospital. Methods: We conducted a retrospective analysis of 32 patients diagnosed with pulmonary actinomycosis between January 2013 and December 2019. General characteristics, clinical manifestations, lab data, chest CT imaging, treatment and follow-up information were reviewed and analyzed. Results: This study consisted of 19 males and 13 females, with a mean age of (58±12) years, ranging from 16 to 76 years. There were 26 cases with co-morbidities. Among them, there were 16 cases with pulmonary co-morbidity. Sixteen cases had a smoking history. Eight cases, 5 men and 3 women, with a mean age of (48±8) years, ranging from 41 to 58 years, received thoracic surgery for diagnosis. The remaining 24 cases who did not receive thoracic surgery consisted of 14 males and 8 females, with a mean age of (54±14)years, ranging from 16 to 76 years. Cough (25cases), expectoration (21 cases) and fever (16 cases) were the common clinical manifestations. The erythrocyte sedimentation rate (ESR) ranged from 2 to 114 mm/1 h, with a mean value of (28±31) mm/1 h. The ESR was elevated (>20 mm/1 h) in 15 cases. The C-reactive protein (CRP) ranged from 1 to 116 mg/L, with a mean value of (28±45) mg/L. The CRP was elevated (>8 mg/L) in 16 cases. Localized air-space consolidation (18 cases), pulmonary mass or nodules (16 cases) were the common chest CT manifestations. When compared with non-surgical cases, fever was the sole characteristic that was less common in cases with thoracic surgery (1 case in surgical group vs 11 cases in non-surgical group, P<0.05). Actinomyces spp. was found in 7 cases (87.5%) who received thoracic surgery, in 16 (61.5%) specimens collected through bronchoscopy and in 10 (55.6%) sputum samples of good quality. All of our enrolled cases were administrated with oral antibiotics, and 14 cases were prescribed with intravenous antibiotics initially. Among them, 27 cases were administrated with more than one antibiotic. Penicillin, ampicillin and amoxillin were prescribed for 25 cases. Finally, 30 cases showed improvement or cure in our hospital. Conclusions: Pulmonary actinomycosis tended to develop in aged patients with co-morbidities. Cough, expectoration, fever and localized air-space consolidation were the common clinical and radiological manifestations, respectively. Actinomyces spp. could be found more easily in the surgically resected tissues than other specimens. The prognosis of our enrolled cases was good after treatment with combined antibiotics.

Objective: To compare the advantages and disadvantages of total arterial revascularization (TAR) and conventional off-pump coronary artery bypass (OPCAB) grafting in patients with left ventricular dysfunction (LVD). Methods: Between January 2008 and March 2015, 76 patients who were scheduled to undergo selective OPCAB were selected for cardiac surgery in Zhongshan Hospital, Fudan University. The left ventricular ejection fraction of enrolled patients was less than 35%. Among those patients, 38 patients in TAR group underwent total arterial OPCAB with bilateral internal mammary artery, left and/or right radial artery, and another 38 patients in control group underwent conventional OPCAB with left internal mammary artery and great saphenous vein. The clinical data of all patients were collected. The follow-up was performed within 36 months. Results: There was no significant difference in preoperative clinical data between the two groups (all P>0.05). Additionally, there was no significant difference in the application rate of internal mammary artery, positive inotropic drugs and intra-aortic balloon pump (IABP) use between the two groups (all P>0.05). The operation time of TAR group was longer than that of control group [(278.3±31.2) min vs (196.7±19.1) min, P<0.01]. There was no significant difference in perioperative mortality between the two groups (5.3% vs 7.9%, P=0.64). The volume of operative drainage and blood transfusion in TAR group increased significantly at 24 hours after operation [(895.0±236.2) ml vs (585.4±172.5) ml, (656.3±84.4) ml vs (433.3±62.9) ml, both P<0.01]. There was no significant difference in perioperative complications such as heart, kidney and lung failure between the two groups (all P>0.05). At 12 months after operation, there were no significant differences in survival rate, cardiac death rate, angina recurrence, myocardial infarction, re-treatment rate of revascularization, re-hospitalization rate from cardiac insufficiency, graft patency rate, cardiac function and echocardiographic data between the two groups (all P>0.05). From 24 to 36 months after operation, all the above indexes in TAR group were better than those in control group except for echocardiographic data (all P<0.05). Conclusions: For LVD patients, the early clinical efficacy of the two surgical methods is similar, but for the long-term outcomes, the whole arterial OPCAB operation is obviously superior. However, the shortcomings of total arterial OPCAB are that operative drainage and the use of blood products increased significantly after operation.

Objectives: Long-term use of inhaled corticosteroids (ICS) was reported as a risk factor for patients with chronic obstructive pulmonary disease (COPD) complicated with nontuberculous mycobacterial lung disease (NTM-LD). But it was not reported often in China. Methods: We conducted a retrospective analysis of patients who were diagnosed with COPD and NTM-LD in our department from January 1(st) 2017 to December 31(th) 2018. Results: This study consisted of 10 male and 5 female patients with a mean age of (66±7) years. The detailed clinical data and radiological images were reviewed systemically. There were 4 current smokers (26.7%) and 6 past smokers (40%). All cases were current ICS users, with a mean duration of (27.3±9.7) months, ranging from 3 months to 61 months. Among them, 8 cases (53.3%) used inhaled fluticasone and 7 cases (46.7%) used inhaled budesonide. Aggravated coughing (15 cases, 100%), expectoration (15 cases, 100%) and dyspnea (10 cases, 66.7%) were the common clinical manifestations, although fever was only reported in 4 cases (26.7%). All cases showed normal white blood cell count and lymphocyte count, and some of them (7 cases, 46.7%) showed elevated erythrocyte sedimentation rate and C-reactive protein. Most of them (14 cases, 93.3%) had normal TB-SPOT results. Multiple focal bronchiectasis (9 cases, 60%) and significant emphysema (12 cases, 80%) were the common manifestations of basic high-resolution CT (HRCT) prior NTM infection. The occurrence of bronchiectasis (15 cases, 100%), "tree in bud" sign (12 cases, 80%) and tiny cavities (8 cases, 53.3%) were the common HRCT abnormalities for the NTM-LD cases. According to the 2007's NTM-LD diagnosis criteria, most of them (13 cases, 86.7%) were diagnosed with positive sputum samples at least twice, and 2 cases were diagnosed with positive CT-directed bronchial alveolar lavage fluid. NTM-PCR analysis was performed routinely for the isolated NTM samples to identify the NTM species. Mycobacterium avium complex (MAC) was the most common NTM species (8 cases, 53.3%). After treatment with proposed anti-NTM strategies, most cases improved (9 cases, 60%), and some of them (4 cases, 26.7%) were cured and a few cases (2 cases, 13.3%) relapsed. Conclusions: When COPD patients treated with ICS showed aggravated cough, expectation and/or dyspnea, and new occurrence of bronchiectasis and/or "tree in bud" sign in the recent HRCT, the differential diagnosis of NTM-LD should be considered. Respiratory samples should be arranged for NTM cultures and PCR analysis as soon as possible. Earlier antimicrobial strategies according to the identified NTM species would improve the clinical outcomes.
