ABSTRACT

Objective:To investigate the effect of teaching practice under the concept of narrative medicine on improving the empathy level of interns in oral mucosal diseases.Methods:The interns of stomatology in the class of 2018 in School of Stomatology, Shanghai Jiao Tong University, were divided into narrative medicine teaching group (27 interns receiving narrative medicine concepts and methods before and during internship) and traditional teaching group (21 interns received patients directly under the guidance of teachers without the addition of narrative medicine concepts and methods). A questionnaire was used to collect the general information of students, and the Chinese version of Jefferson Scale of Physician Empathy (JSPE) (the version for medical students) was used to measure the empathy level of students. After the end of internship, a statistical analysis was performed for the scores of both groups, and a questionnaire survey was conducted to investigate the acceptance of internship under the guidance of narrative medicine among the students in the narrative medicine teaching group. GraphPad Prism 9.3.0 was used to perform the t-test and the rank sum test. Results:There was a significant difference in JSPE score between the traditional teaching group and the narrative medicine teaching group (92.26±8.23 vs. 104.20±15.65, t=2.70, P=0.005), and in addition, 88.89% (24/27) of the students in the narrative medicine teaching group were interested in participating in internship under the guidance of narrative medicine. However, there was no significant difference in the score of internship between the narrative medicine teaching group and the traditional teaching group (87.28±2.77 vs. 85.47±4.31, t=1.68, P=0.100). Conclusions:Incorporating the concepts and methods of narrative medicine into clinical teaching of oral mucosal diseases can significantly improve the empathy ability of interns and raise the awareness that empathy is as important as scientific literacy among students.

ABSTRACT

Objective:To analyse the changes in color Doppler and contrast-enhanced ultrasound (CEUS) blood flow parameters in patients with septic acute kidney injury (AKI) from the perspective of macroscopic circulation and microscopic circulation perfusion, in order to explore the value of clinical application of ultrasound in this disease.Methods:A total of 53 ICU-admitted patients diagnosed with septic AKI at the Second Affiliated Hospital of Soochow University from January 2021 to May 2022 were selected.Patients with septic AKI were classified into stages 1-3 according to the 2012 Kidney Disease: Improving Global Outcomes (KDIGO) AKI diagnostic criteria, with stage 1 being the mild group(17 cases), stages 2 and 3 being the severe group(21 cases), and septic patients without AKI in the same period being the control group(15 cases). The ultrasound parameters such as the relative blood flow(RBF) and time-averaged velocity(TAV) of the renal artery as well as the cardiac output (CO) and cardiac index (CI) in the macroscopic circulation were measured, and the time-intensity curve was analysed by the CEUS analysis software to calculate the microscopic parameters such as time to peak(TTP), rise time(RT), fall half time(FHT) and mean transit time(MTT), and the cardiac output and cardiac index were also measured. The differences in ultrasound Doppler and CEUS parameters among the various groups were compared. The diagnostic effectiveness of each parameter for severe AKI was assessed using ROC curve analysis.Results:①In macrocirculation, the renal blood flow (RBF) and time-averaged velocity (TAV) gradually decreased ( P=0.004, P<0.001) as the disease progressed in AKI patients. But the difference of CO and CI among the three groups were not statistically significant in each group ( P=0.17, 0.12). ②In microcirculation, the renal interlobar artery Doppler parameters pulsatility index (PI), resistance index (RI), and systolic/diastolic flow ratio (S/D) gradually increase in patients with septic AKI ( P<0.05) and the CEUS parameters TTP, RT, FHT and MTT were prolonged ( P<0.001, P=0.003, P=0.004, P=0.009). ③The combined diagnosis of RI and TTP was more beneficial in diagnosing septic AKI in critically ill patients [AUC=0.93(0.85-1.00)]. Conclusions:Color Doppler ultrasound combined with CEUS can detect reduced macroscopic and microscopic circulation in patients with septic AKI, especially in those with severe AKI, and this is independent of changes in CO or CI.

ABSTRACT

Objective:To analyze the clinical and laboratory characteristics of acute myeloid leukemia (AML) patients with NPM1 mutation, and to explore the prognostic factors.Methods:A total of 77 AML patients with NPM1 gene mutation admitted to Hebei Yanda Ludaopei Hospital from May 1st 2012 to December 31st 2021 were enrolled in the study, including 34 male and 43 female patients. The median age was 40 (3, 68) years old. Patients were selected and divided into 4 groups according to the morphological FAB classification. There were 29 cases (37.7%) of M1 type, 13 cases (16.9%) of M2 type, 23 cases (29.9%) of M4 type, and 12 cases (15.5%) of M5 type. The clinical characteristics, bone marrow/peripheral blood cell morphology, immunophenotype, cytogenetics, molecular biology and overall survival of different groups were retrospectively analyzed, and the risk factors affecting the prognosis of AML were also explored. Cox multivariate regression was used to analyze the clinical influencing factors of survival and prognosis.Results:The white blood cell counts were highest in M4 and M5 patients and lowest in M2 patients, while no significant difference in the red blood cell, hemoglobin, and platelet counts( P>0.05). Morphologically, there were significant differences in the percentage of blasts and blasts with cup-like nuclei on bone marrow (BM) and peripheral blood (PB). The proportion of blasts in BM and PB was the highest in M1 and the lowest in M2 ( P<0.001). The positive rate of blasts with cup-like nuclei was the highest in M1 and the lowest in M5 of BM ( P<0.001), while the highest in M2 and the lowest in M5 of PB ( P=0.006). The scores of myeloperoxidase and chloroacetate esterase were all the highest in M1 and the lowest in M5 ( P<0.001, 0.001, respectively). In terms of molecular biology, the occurence rate of blasts combined with DNMT3A mutation was the highest in M4 and the lowest in M2 ( P=0.044), while those combined with FLT3-ITD mutation was the highest in M4 and the lowest in M5 ( P=0.002). In immunophenotype, there were significant differences in the expression positivities of seven antigens including HLA-DR, CD56, CD11c, CD15, CD14, CD96 and cMPO ( P<0.05). Multivariate COX regression analysis showed that no recurrence after treatment ( P<0.001), complete remission after treatment ( P=0.015) and transplantation ( P<0.001) were correlated with overall survival (OS). No recurrence after treatment ( P=0.033), transplantation ( P=0.027), no mutation of FLT3-ITD ( P=0.040), and hemoglobin concentration ( P=0.023) were associated with relapse-free survival (RFS). Survival analysis by Kaplan-Meier curve showed that there was no significant difference in survival time between the M1, M2, M4 and M5 groups in OS and RFS. Conclusion:There were significant differences in the white blood count, the percentage of blasts and blasts with cup-like nuclear morphology, cytochemical staining (MPO integration, CE integration and percentage of NAS-DCE), gene mutation (DNMT3A and FLT3-ITD) and immunophenotypes (HLA-DR, CD56, CD11c, CD15, CD14, CD96 and cMPO) between the four groups. The multivariate analysis revealed that no recurrence after treatment and transplantation were independent prognostic factors in NPM1 mut AML patients. On the other hand, FLT3-ITD mutation and hemoglobin concentration were associated with RFS and complete remission after treatment was associated with OS in the entire NPM1 mut cohort.

ABSTRACT

Infertility is gradually becoming a major problem affecting health worldwide, and male factors also play an important role in infertility. Extracellular vesicles (EVs) are ultramicro membranous vesicles released by cells during activation or apoptosis, which play an important role in cell communication. Relevant studies have shown that extracellular vesicles contain a variety of bioactive substances and participate in infertility related pathophysiological processes by influencing the content of intercellular transmission. Therefore, we reviewed the relationship between extracellular vesicles and male infertility, and expounded the occurrence and potential treatment of male infertility from another perspective.

ABSTRACT

To study the clinical features of myeloperoxidase(MPO) antineutrophil cytoplasmic antibody (ANCA) associated hypertrophic pachymeningitis (HP). Clinical data of 15 cases diagnosed with MPO-ANCA vasculitis complicated with HP were retrospectively analyzed. Nine cases were males and the other 6 were females, with an average age of (58±8) years. All cases presented with chronic headache. Contrast-enhanced magnetic resonance imaging (MRI) scan showed local or diffused thickening of cerebral and/or spinal dura matter while brain parenchyma were normal. Nine cases developed multiple cranial nerve paralysis, with trigeminal nerve and auditory nerve involved most commonly. The main clinical manifestations were facial pain, hearing loss and tinnitus. Two cases were complicated with hypertrophic spinal pachymeningitis (HSP) and 4 cases were complicated with pulmonary diseases. Positive serum perinuclear pattern ANCA (pANCA) and MPO could be found in all cases, positive serum IgG 4 was seen in two patients. erythrocyte sedimentation rate(ESR;25-116 mm/1h) and C-reactive protein (CRP;29.02-146.00 mg/L) were both elevated in 14 cases. Nine cases had elevated intracranial pressure[180-235 mmH 2O (1 mmH 2O=0.009 8 kPa)] and abnormal protein level (457.6-3710.0 mg/L) in cerebrospinal fluid. Six cases were treated with glucocorticoids (prednisone 20-60 mg/d) and 9 cased with glucocorticoids and immunosuppressants (methotrexate 15 mg/week or cyclophosphamide 100 mg/d po). All patients achieved remission. MPO-ANCA associated HP is a special type of central nervous system involvement in ANCA associated vasculitis (AAV). It rarely involves the lung or kidney. Steroids and immunosuppressive agents are effective. In HP with unknown underlying diseases, it is suggested to screen ANCA and IgG 4 tests for AAV or IgG 4-related disease.

ABSTRACT

Objective:To explore the effectiveness and complications of non-incision removal of tunneled cuffed catheter (TCC).Methods:The clinical characteristics, surgical plans and complications of patients with TCC removal in the Renal Division of Peking University First Hospital from January 1, 2015 to December 31, 2020 were collected and analyzed retrospectively. The patients were divided into non-incision removal group and traditional incision removal group. The clinical characteristics, procedure success rate, procedural duration and complications were compared between the two groups.Results:A total of 349 patients were included in this study, for whom 368 catheter removal procedures were performed, including 286 procedures in the non-incision removal group, 75 procedures in the traditional incision removal group, and 7 procedures without records of surgical plans. There was no significant difference in age, sex, basic kidney diseases and catheter remaining time and location between the two groups (all P>0.05). Two procedures in the non-incision removal group and 1 procedure in the traditional incision removal group failed respectively, and there was no significant difference in the procedure success rate between the two groups (99.3% vs 98.7%, χ2=0.290, P=0.590). The procedural duration in the non-incision removal group was lower than that in the traditional incision removal group [(5.36±1.70) min vs (17.55±3.28) min, t=44.198, P<0.001]. Among the patients who needed TCC exchange, there was no significant difference in the selection of new catheter position between the two groups ( P=0.330). In terms of complications, there were 2 procedures of local hematoma in the non-incision removal group and 1 procedure of infection in the traditional incision removal group, and there was no severe complication in both groups. Conclusions:There was no significant difference in the procedural success rate and complications between non-incision removal group and traditional incision removal group, and non-incision procedure may be superior in reducing the procedure duration and harm less to the patients. Non-incision procedure is a safe and effective method to remove TCC.

ABSTRACT

【Objective】 To investigate the clinical characteristics and potential mechanism of coronavirus disease 2019 (COVID-19) vaccine-related myocarditis. 【Methods】 We made a systematic literature retrieval based on PubMed to search for all reports on COVID-19 vaccine-related myocarditis published by August 31, 2021. A total of 29 reports involving 71 patients with myocarditis were enrolled after screening. The patients’ demographic data, vaccination, clinical manifestations, biochemical and imaging results, treatments, and outcomes were extracted and summarized. The patients were divided into prior COVID (n=12) and non-prior COVID (n=59) according to their previous medical history. 【Results】 COVID vaccine-related myocarditis was more common in men (91.5%) and after the second dose of mRNA vaccine (81.7%). The average time to onset was 3 (1, 25) days, and the main symptoms included chest pain (94.4%), fever (45.1%), myalgia (26.8%), and shortness of breath (16.9%). Abnormal troponin level was present in almost all the patients, with a common elevation of C-reactive protein. Non-steroidal anti-inflammatory drugs and colchicine were widely used in clinical treatment, and the symptoms of one-fifth of the patients were relieved after symptomatic therapy, with 1 to 2 weeks’ length of hospital stay. However, the risk of vaccine-related myocarditis was significantly increased in patients with previous COVID-19 infection, which was more common after the first dose of vaccine (58.3%) other than the second dose. And the clinical symptoms and outcomes were somewhat different from those without COVID-19 infection previously. 【Conclusion】 Myocarditis is one of the serious adverse events related to COVID-19 vaccine, with an overall relatively low incidence, mild clinical severity, and favorable prognosis. Vaccine-related myocarditis may be a combined result of primed immune system and individual susceptibility after infection with COVID-19.

ABSTRACT

【Objective】 To investigate the association of platelet/albumin ratio (PAR), platelet/hemoglobin (PHR) and C-reactive protein/albumin (CAR) with diabetes mellitus. 【Methods】 Based on the data of China Health and Nutrition Survey (CHNS2009), with gender and age matched by their ID, a total of 8 258 individuals with serological test results were finally included and were divided into diabetes group and control group according to the fasting blood glucose and HbA1c, and then the blood lipid and blood cell changes, PAR, PHR and CAR differences between groups were compared, and the correlation analysis of diabetes was performed. 【Results】 Compared with those in the control group, serum uric acid, total cholesterol, triacylglycerol and low-density lipoprotein cholesterol (LDL-C) were significantly increased in diabetes group, while high-density lipoprotein cholesterol (HDL-C) was significantly decreased. Besides, there was no significant difference in PAR or PHR between the two groups, while CAR was significantly increased in diabetes (0.48±0.18 vs. 0.08±0.23, P<0.001), and was positively correlated with the levels of fasting glucose (r=0.181 8, P<0.001), HbA1c (r=0.186 6, P<0.001), and HOMA-IR (r=0.188 1, P=0.003). However, CAR was not an independent risk factor for diabetes. In addition, increased red blood cell count (B=1.324, 95% CI: 1.182-1.483, P<0.001) and leukocytes count (B=1.230, 95% CI: 1.166-1.298, P<0.001) may be independent risk factors for the incidence of diabetes. 【Conclusion】 CAR is correlated with diabetes mellitus, but it is not an independent risk factor. Dyslipidemia, elevated leukocytes and red blood cell counts may be independent risk factors for diabetes, but further study is needed.

ABSTRACT

Objective:To investigate the significant effects of enhanced whole-body computed tomography (EWBCT) and non-enhanced whole-body computed tomography (N-EWBCT) on the missed diagnosis rate, renal function and prognosis of patients with severe trauma.Methods:Clinical data of trauma patients admitted from January 1, 2017 to December 31, 2020 were collected from the trauma database of the Trauma Center of the Second Affiliated Hospital of Soochow University. All patients included in this study were divided into the EWBCT group and N-EWBCT group according to whether they underwent enhanced whole-body computed tomography examination. The differences in baseline data, missed diagnosis rate, renal function and prognosis of the two groups of patients were compared.Results:A total of 459 patients were included in this study, including 184 patients in the EWBCT group and 275 patients in the N-EWBCT group. The missed diagnosis rate of the N-EWBCT group was significantly higher than that of the EWBCT group (18% vs. 5%, P < 0.01). The risk ratio of acute kidney injury (AKI) in the EWBCT group and N-EWBCT group was 9% and 7%, respectively, and there was no statistical difference between the two groups ( P >0.05). The mortality rate of patients in the N-EWBCT group was higher than that in the EWBCT group (23% vs. 12%, P=0.002). Conclusions:Compared with N-EWBCT, EWBCT does not significantly increase the risk of renal damage in patients with severe trauma. For patients with severe trauma, early EWBCT can reduce the missed diagnosis rate and improve the clinical prognosis.

ABSTRACT

Objective:To investigate the correlation between the imaging markers of cerebral small vessel disease (CSVD) and early hematoma expansion (HE) in patients with spontaneous intracerebral hemorrhage (sICH).Methods:Patients with sICH admitted to the Department of Neurology, the Affiliated Hospital of Qingdao University between January 1, 2015 and December 31, 2019 were enrolled retrospectively. All patients received noncontrast CT (NCCT) within 6 h after onset. Within 24 h after the initial NCCT examination, they were reexamed to determine whether HE occurred, and brain MRI examination was completed within 48 h after onset. HE was defined as the increase of hematoma volume on NCCT reexamination by >33% or >6 ml compared with the baseline. NCCT was used to evaluate the abnormal morphology and density signs, including blend sign, swirl sign, black hole sign, island sign, and satellite sign. MRI was used to evaluate CSVD imaging markers, including lacunar infarcts (LIs), enlarged perivascular space (EPVS), white matter hyperintensities (WMHs), cerebral microbleeds (CMBs), and cortical superficial siderosis (CSS). Multivariate logistic regression analysis was used to determine independent risk factors for HE. The receiver operator characteristic (ROC) curve was used to evaluate the predictive ability of imaging markers for HE in patients with sICH. Results:A total of 216 patients with sICH were included. Their age was 57±15 years, 113 (61.6%) were male, 88 (40.7%) had HE, 123 (56.9%) had NCCT signs, 122 (56.5%) had CMBs, 143 (66.2%) had WMHs, 44 (20.4%) had CSS, 25 (11.6%) had LIs, and 31 (14.4%) had EPVS. The baseline hematoma volume, blood calcium, the modified Rankin Scale score and the National Institutes of Health Stroke Scale score at admission, and detection rates of NCCT signs, CMBs, WMHs and CSS in the HE group were significantly higher than those in the non-HE group (all P<0.05). Multivariate logistic regression analysis showed that the blood calcium (odds ratio [ OR] 0.040, 95% confidence interval [ CI] 0.004-0.238; P=0.001), any NCCT signs ( OR 3.275, 95% CI 1.492-7.188; P=0.003), CMBs grade 4 ( OR 3.591, 95% CI 1.146-11.250; P=0.028), CSS ( OR 3.008, 95% CI 1.214-7.452; P=0.017), NCCT signs+ CMBs grade 3 ( OR 3.390, 95% CI 1.035-11.102; P=0.044), NCCT signs+ CMBs grade 4 ( OR 5.473, 95% CI 1.352-22.161; P=0.017), and NCCT signs+ CSS ( OR 3.544, 95% CI 1.215-10.336; P=0.021) were the independent risk factors for HE in patients with sICH. ROC curve analysis showed that the sensitivity of NCCT signs, CMBs and CSS for predicting HE were 81.8%, 64.8% and 34.1%, respectively, and the specificity were 60.2%, 60.9% and 89.1%, respectively. The predictive sensitivity of NCCT signs+ CMBs and NCCT signs+ CSS (59.1% and 30.7%, respectively) was lower than that of single imaging marker, while the specificity (78.1% and 93.7%, respectively) was higher than that of single imaging marker. Conclusions:The imaging markers of CSVD are closely associated with the risk of HE in patients with sICH. Severe CMBs and CSS are the independent risk factors for HE in patients with sICH. The specificity of NCCT signs combined with CSVD imaging markers for predicting HE is increased but the sensitivity decreased.

ABSTRACT

Objective:To observe the changes of regional saturation of cerebral oxygenation (rScO 2) and blood neuron specific enolase (NSE) in patients after cardiopulmonary resuscitation (CPR), and to explore its value in evaluating the prognosis of patients' neurological function. Methods:From January 2012 to December 2020, 97 patients with return of spontaneous circulation (ROSC) after cardiac arrest (CA) treated in the intensive care unit (ICU) of the Second Affiliated Hospital of Soochow University were selected. According to the prognosis, the patients were divided into two groups: good neurological function group [Glasgow-Pittsburgh Cerebral Performance Categories (CPC) 1-2, 20 cases] and neurological dysfunction group (CPC classification 3-5, 77 cases). The clinical data of gender, age, the number of patients with defibrillable rhythm, time of ROSC, the number of CA patients outside the hospital, acute physiology and chronic health evaluationⅡ(APACHEⅡ), Glasgow coma scale (GCS), global non-response scale (FOUR), body temperature, mean arterial pressure (MAP), blood lactic acid (Lac) and GCS at discharge, as well as the length of ICU stay, rScO 2 and blood NSE were collected. The differences of rScO 2 and NSE between the two groups were compared; and the receiver operator characteristic curve (ROC curve) was drawn to evaluate the value of rScO 2 and NSE alone or in combination in predicting the prognosis of patients with ROSC after CA. Results:The rScO 2 of good neurological function group was significantly higher than that of neurological dysfunction group at 1, 3, 6, 12, 24 and 48 hours (all P < 0.05). At 24 hours after admission, the rScO 2 on the left and right sides of good neurological function group was significantly higher than that in neurological dysfunction group [left: 0.65 (0.59, 0.76) vs. 0.55 (0.44, 0.67), right: 0.62 (0.61, 0.73) vs. 0.50 (0.30, 0.69), both P < 0.05], and NSE was significantly lower than that in the neurological dysfunction group [ng/L: 21.42 (15.38, 29.69) vs. 45.82 (24.05, 291.26), P < 0.05]. ROC curve analysis showed that both rScO 2 and NSE alone and combined detection had a certain value in predicting the prognosis of neurological function in patients with ROSC after CA, and the area under the ROC curve (AUC) detected by the combination was the largest, which was higher than the AUC predicted by rScO 2 or NSE (0.904 vs. 0.884, 0.792). When the cut-off value of combination was 0.83, the sensitivity and specificity were 75.7% and 100% respectively. Conclusion:Monitoring rScO 2 and NSE can predict the prognosis of neurological function after CPR, especially the combined evaluation of the two indexes, which can greatly improve the accuracy of diagnosis.

ABSTRACT

Objective:To deliver understanding of the latest research progress on clinical trials and approval of dermatological drugs in China in 2020.Methods:A registration and information disclosure platform for drug clinical studies and a query system for domestic and imported drugs in the National Medical Products Administration of China were searched for registered clinical trials and approved dermatological drugs, respectively. The number and stages of clinical trials, indications and classification of involved products, and listed dermatological drugs in 2020 were summarized and depicted.Results:There were 157 dermatological drug trials registered in China in 2020, accounting for 6.16% of all the 2 548 clinical drug trials, including 127 (80.9%) initiated by Chinese pharmaceutical enterprises and 25 (15.9%) international multicenter trials. Among the 127 drug trials initiated by Chinese pharmaceutical enterprises, bioequivalence trials were mostly common, accounting for 55.9% (71/127) . Compared with global pharmaceutical enterprises, domestic pharmaceutical companies initiated significantly decreased proportions of international multicenter trials (1.9% [3/157] vs. 14.0% [22/157], P < 0.001) , but significantly increased proportions of phaseⅠclinical trials and bioequivalence trials (24.4% [31/127] vs. 10.0% [3/30], 55.9% [71/127] vs. 0, respectively, both P < 0.001) . Totally, 90 kinds of dermatological drug were involved in all the trials, psoriasis, atopic dermatitis and melanoma were the most common indications, and innovative drugs accounted for 53.3% (48/90) ; the proportion of innovative drugs was significantly lower in domestic pharmaceutical companies than in global pharmaceutical companies (43.2% [32/74] vs. 16/16, P < 0.001) . In addition, 28 dermatological drugs developed by 22 pharmaceutical companies were approved in China in 2020, of which 21 drugs were developed by domestic pharmaceutical companies. Conclusion:Clinical drug trials carried out by domestic pharmaceutical companies mostly focus on generic drugs, and it is still necessary for domestic pharmaceutical companies to further improve the innovation ability.

Objective:To provide clinical experience for the diagnosis and treatment of spontaneous renal hemorrhage through retrospective analysis of clinical features, imaging manifestations, underlying causes, treatment , and prognosis of spontaneous renal hemorrhage. Methods:By searching hospital information system, medical records scanning system, department of the interventional vascular surgery registry system, and picture archiving and communication systems, the patients with spontaneous renal hemorrhage admitted to Peking University First Hospital between January 1, 2000 to April 10, 2020 were enrolled. The clinical manifestations, investigations, imaging features, treatment, and prognosis of patients were retrospectively reviewed. The diagnostic efficiency and the accuracy of etiological diagnosis of renal hemorrhage by imaging examinations such as ultrasound, computed tomography (CT), magnetic resonance imaging (MRI), and angiography were compared and evaluated.Results:A total of 50 patients with 51 events of spontaneous renal hemorrhage were enrolled in the study. Laboratory tests showed hemoglobin was (103.3±29.4) g/L. The most common clinical features were flank or abdominal pain (48 cases, 96.0%), fever (17 cases, 34.0%), nausea (10 cases, 20.0%), vomiting (9 cases, 18.0%), and gross hematuria (4 cases, 8.0%). Nine patients (18.0%) experienced hypovolemic shock (systolic pressure<90 mmHg). With an initial assessment of the imaging method, the diagnostic accuracy of bleeding was 98.0%(49/50), yet the accuracy of underlying causes was 56.0%(28/50). The diagnostic accuracy of bleeding was 100.0%(25/25) by non-contrast abdominopelvic CT. The most common cause of spontaneous renal hemorrhage syndrome was renal tumors (27 cases, 54.0%), among which angiomyolipoma occurred most frequently (20 cases, 40.0%). Other causes included renal cyst (10 cases, 20.0%), autoimmune diseases (4 cases, 8.0%), bleeding diathesis (3 cases, 6.0%), and idiopathic renal hemorrhage (6 cases, 12.0%). Twelve patients (24.0%) received conservative management, 29 patients (58.0%) underwent interventional embolization therapy, and 11 patients (22.0%) received nephrectomy. The success rate on first embolization therapy was 86.2%(25/29), and approximately 13.8%(4/29) required second embolization therapy or nephrectomy.Conclusions:Spontaneous renal hemorrhage has no specific clinical features and is easy to be underdiagnosed or misdiagnosed. Non-contrast CT scan has a high diagnostic value for renal bleeding. Comprehensive judgement consisting of clinical features, laboratory tests, imaging manifestations and pathological examinations should be relied on for finding the underlying causes. Prompt diagnosis and management can guarantee a better prognosis.

ABSTRACT

Objective:To investigate the risk factors and establish a risk scoring system for bronchopulmonary dysplasia (BPD) in very and extremely preterm infants.Methods:From December 2013 to December 2018, 254 very and extremely preterm infants with less than 32 weeks of gestation hospitalized for 28 d and above in the Third Staff Hospital of Baotou Steel Group were retrospectively enrolled. According to the diagnostic criteria of BPD, they were divided into the BPD group ( n=129) or the non-BPD group ( n=125). Clinical data and the risk factors for BPD were analyzed with univariate t-test, Chi-square test, rank-sum test, and multivariate logistic regression analysis. Based on the results, the risk scoring system was evaluated by receiver operating characteristic (ROC) curve, sensitivity, and specificity. Results:Logistic regression analysis showed that gestational age, neonatal respiratory distress syndrome (NRDS), ventilator-associated pneumonia (VAP), and duration of ventilation >7 d were the risk factors for BPD (all P<0.05). When the area under the ROC curve was 0.868 (95% CI: 0.823-0.913, P<0.001) and the maximum Youden index was 0.644, the sensitivity of the scoring systems for BPD was 0.884 (95% CI: 0.812-0.931), and the specificity was 0.760 (95% CI: 0.674-0.830). Conclusions:Gestational age, NRDS, VAP, and prolonged duration of ventilation were the risk factors for BPD. The risk scoring system established has the prediction value on BPD in very and extremely preterm infants.

ABSTRACT

Objective:To compare the therapeutic outcomes between use of antibiotic cement versus non-use of antibiotic cement in the treatment of tibial osteomyelitis after radical debridement.Methods:A retrospective analysis was made of the 68 patients with local tibial osteomyelitis of Cierny-Mader Type Ⅳ who had been treated at Department of Orthopaedic Trauma, The Second People’s Hospital of Shenzhen from January 2010 to June 2015. The dead space was filled with antibiotic-impregnated bone cement beans after radical debridement of the infected bone in 32 of them (cement group) but was not in 36 of them (no-cement group). The operations for both groups were performed by the same surgical team who filled the bone defects after excision of infected bone using Ilizarov bone transport. The 2 groups were compared in terms of Paley functional scores of bone and limb, external fixation index (EFI), infection recurrence rate, total hospital costs and other complications.Results:The 2 groups were comparable because there was no significant difference between them in the preoperative general data ( P>0.05). The cement group was followed up for (71.2±8.9) months and the no-cement group for (71.6±9.7) months, showing no significant difference ( P>0.05). By the Paley functional scores, the good to excellent rate for bone was 100% for both groups (32/32 versus 36/36) while the good to excellent rate for limb was 93.8% (30/32) for the cement group and 94.4% (34/36) for the no-cement group, showing no significant differences between them ( P>0.05). The EFI was (49.0±10.5) d/cm for the cement group and (49.5±11.4) d/cm for the no-cement group, showing no significant differences between them ( P>0.05). The infection recurrence rate at the final follow-up was 3.12% (1/32) for the cement group and 2.78% (1/36) for the no-cement group, showing no significant differences between them ( P>0.05). The total hospital cost was (70,944.1 ± 1,135.5) Yuan RMB for the cement group and (55,205.2 ± 897.3) Yuan RMB for the no-cement group, showing a significant difference ( P<0.05). No serious complications with sequelae were found in either of the 2 groups. Conclusion:In the treatment of local tibial osteomyelitis of Cierny-Mader Type Ⅳ, it is not necessary to fill the dead space with antibiotic cement when radical debridement is achieved.

ABSTRACT

Objective:To explore the efficacy and safety of ticagrelor versus clopidogrel in acute coronary syndrome (ACS) Chinese patients using glycoprotein Ⅱb/Ⅲa inhibitor (GPI).Methods:The data from CCC-ACS (Improving Care for Cardiovascular Disease in China-ACS) project were systematically reviewed in ACS patients with GPI. The patients were divided into ticagrelor and clopidogrel groups. A logistic analysis and propensity score matching (PSM) were performed to compare occurrences of major cardiovascular events (MACE) and bleeding events between the two groups during hospitalization.Results:A total of 63 641 ACS patients were collected from 150 hospitals. Logistic regression analyses showed that there was no statistically significant difference in the reduction of MACE between ticagrelor and clopidogrel when using GPI ( OR=0.881, 95% CI 0.599-1.296; P=0.521). However, major bleeding rate was higher in the ticagrelor group than that in the clopidogrel group ( OR=1.401, 95% CI 1.075-1.852; P=0.013). Similar results were observed after PSM. No statistic difference in MACE between the ticagrelor and clopidogrel group ( OR=0.919, 95% CI 0.613-1.376; P=0.681). Major bleeding rate was higher in the ticagrelor group ( OR=1.559, 95% CI 1.130-2.150; P=0.007). Conclusion:In ACS patients with GPI, ticagrelor did not reduce MACE, but increased the major bleeding risk compared with clopidogrel.
