ABSTRACT

@#Amblyopia is the leading cause of visual impairment in children. It is also one of the main causes of monocular vision loss in adults. It is effectively treated using correct treatment when initiated during the sensitive period of visual development. Historically, patching or other means of penalization following refractive correction has been the main treatment for amblyopia. With the advancing of exploration on the neural mechanism of amblyopia, binocular treatment has been proposed as an innovative method for the treatment of amblyopia. Different forms of binocular treatment were reported by researchers. This review will focus on the application and progress of binocular treatment in amblyopia.

ABSTRACT

Objective:To analyze and evaluate the effect of OX40L as a potential adjuvant for H7N9 whole-virion inactivated vaccine (WIV).Methods:Fifty BALB/c mice were randomly divided into five groups and immunized intramuscularly with PBS (control group) and 1.5 μg WIV alone or in combination with 0.6, 1.8 or 3.0 μg Fc-fused OX40L (OX40L/Fc) adjuvant. Three weeks after immunization, IgG, IgG1 and IgG2 titers were measured by ELISA and hemagglutination inhibition (HI) assay. Moreover, the mice were challenged with 50×median lethal dose (LD 50) of homologous virus and the changes in mouse body weight and survival rate were recorded to evaluate the effects of OX40L. Flow cytometry was used to analyze the mechanism of OX40L as an adjuvant 7 d after immunization. Results:Compared with immunization with WIV alone, co-immunization of WIV with OX40L/Fc induced higher antigen-specific IgG in mice. The geometric mean titers (lgGMT) of antibodies induced by 0.6, 1.8 and 3.0 μg OX40L/Fc reached 3.79, 4.40 and 4.20, respectively. WIV combined with OX40L/Fc induced high levels of IgG1 and IgG2a without influencing Th1/Th2 balance. HI antibodies were also higher in WIV+ 1.8 μg OX40L/Fc and WIV+ 3.0 μg OX40L/Fc groups than in WIV group (6.25±0.50 and 5.70±0.97 vs 3.00±0.97, both P<0.05). WIV combined with 1.8 or 3.0 μg OX40L/Fc could protect 80% or 75% of mice against lethal challenge with H7N9 and result in less weight loss as compared with WIV alone. The most effective dose of OX40L/Fc was 1.8 μg. Flow cytometry showed that WIV (0.6, 1.8, 3.0 μg) in combination with OX40L/Fc enhanced the proliferation of T follicular helper cells (Tfh) through promoting the expression of CXCR5 and PD-1 as compared with WIV alone (all P<0.05). Conclusions:This study suggested that OX40L was beneficial to potent antibody responses induced by H7N9 WIV through promoting Tfh cell proliferation.

ABSTRACT

Objective:To explore the effects of interpregnancy interval (IPI) on pregnancy outcomes of subsequent pregnancy.Methods:A multicenter retrospective study was conducted in 21 hospitals in China. Information of age, height, pre-pregnancy weight, IPI, history of diseases, complications of pregnancy, gestational age of delivery, delivery mode, and pregnancy outcomes of the participants were collected by consulting medical records of pregnant women who had two consecutive deliveries in the same hospital during 2011 to 2018. The participants were divided into 4 groups according to IPI:<18 months, 18-23 months, 24-59 months and ≥60 months. According to the WHO′s recommendation, with the IPI of 24-59 months group as a reference, to the effects of IPI on pregnancy outcomes of subsequent pregnancy were analyzed. Stratified analysis was further carried out based on age, history of gestational diabetes mellitus (GDM), macrosomia, and premature delivery, to explore the differences in the effects of IPI on pregnancy outcomes among women with different characteristics.Results:A total of 8 026 women were included in this study. There were 423, 623, 5 512 and 1 468 participants in <18 months group, 18-23 months group, 24-59 months group and ≥60 months group, respectively. (1) The age, pre-pregnancy body mass index (BMI), history of cesarean section, GDM, gestational hypertension and cesarean section delivery rate of <18 months group, 18-23 months group, 24-59 months group and ≥60 months group were gradually increased, and the differences were statistically significant ( P<0.05). (2) After adjusting for potential confounding factors, compared with women in the IPI of 24-59 months group, the risk of premature delivery, premature rupture of membranes, and oligohydramnios were increased by 42% ( OR=1.42, 95% CI: 1.07-1.88, P=0.015), 46% ( OR=1.46, 95% CI: 1.13-1.88, P=0.004), and 64% ( OR=1.64, 95% CI: 1.13-2.38, P=0.009) respectively for women in the IPI≥60 months group. No effects of IPI on other pregnancy outcomes were found in this study ( P>0.05). (3) After stratified by age and adjusted for confounding factors, compared with women in the IPI of 24-59 months group, IPI≥60 months would significantly increase the risk of oligohydramnios for women with advanced age ( OR=2.87, 95% CI: 1.41-5.83, P=0.004); and <18 months could increase the risk of premature rupture of membranes for women under the age of 35 ( OR=1.59, 95% CI: 1.04-2.43, P=0.032). Both the risk of premature rupture of membranes ( OR=1.58, 95% CI: 1.18-2.13, P=0.002) and premature delivery ( OR=1.52, 95% CI: 1.07-2.17, P=0.020) were significantly increased in the IPI≥60 months group. After stratified by history of GDM and adjusted for confounding factors, compared with women in the IPI of 24-59 months group, IPI≥60 months would lead to an increased risk of postpartum hemorrhage for women with a history of GDM ( OR=5.34, 95% CI: 1.45-19.70, P=0.012) and an increased risk of premature rupture of membranes for women without a history of GDM ( OR=1.44, 95% CI: 1.10-1.90, P=0.009). After stratified by history of macrosomia and adjusted for confounding factors, compared with women in the IPI of 24-59 months group, IPI≥60 months could increase the proportion of cesarean section for women with a history of macrosomia ( OR=4.11, 95% CI: 1.18-14.27, P=0.026) and the risk of premature rupture of membranes for women without a history of macrosomia ( OR=1.46, 95% CI: 1.12-1.89, P=0.005). After stratified by history of premature delivery and adjusted for confounding factors, compared with women in the IPI of 24-59 months group, IPI≥60 months would significantly increase the risk of premature rupture of membranes for women without a history of premature delivery ( OR=1.47, 95% CI: 1.13-1.92, P=0.004). Conclusions:Both IPI≥60 months and <18 months would increase the risk of adverse pregnancy outcomes in the subsequent pregnancy. Healthcare education and consultation should be conducted for women of reproductive age to maintain an appropriate IPI when they plan to pregnant again, to reduce the risk of adverse pregnancy outcomes in the subsequent pregnancy.

ABSTRACT

Objective:To evaluate the radiologic and clinical outcomes of supramalleolar dome osteotomy in the treatment of varus-type ankle arthritis.Methods:From June 2018 to December 2019, 13 patients with varus-type ankle arthritis underwent supramalleolar dome osteotomy at Department of Foot and Ankle Surgery, Beijing Jishuitan Hospital. Of them, 13 (5 males and 8 females) were included in the study. Their average age at surgery was 47.2 years (range, from 16 to 65 years). By the modified Takakura staging for arthritis, 3 cases were stage 2, 4 cases stage 3a and 6 cases stage 3b. Comparisons were made between preoperation and the last follow-up in ankle-hindfoot score of American Orthopedic Foot and Ankle Society (AOFAS), foot function index (FFI), visual analogue scale (VAS), Takakura staging, dorsal extension, plantar flexion, range of motion (ROM), tibial anterior surface angle (TAS), tibial lateral surface angle (TLS), and talar tilt (TT).Results:This cohort were followed up for 12 to 29 months (average, 17.2 months). At the last follow-up, AOFAS score (86.5±8.0), FFI (14.5±1.6), VAS score (1.5±1.0), Takakura staging (2.7±1.3), ROM (39.4°±8.0°), TAS (92.4°±6.0°), TT (3.7°±4.4°) were significantly improved than the preoperative values (68.3±14.4, 43.7±3.0, 4.2±1.4, 3.2±0.8, 43.3°±7.6°, 78.2°±8.3° and 7.0°±5.1°), and dorsal extension (10.9°±4.4°) was significantly smaller than the preoperative value (13.6°±5.1°) (all P<0.05). There were no significant differences between preoperation and the last follow-up in plantar flexion (29.7°±4.6° versus 28.5°±5.2°) or TLS (77.8°±4.5° versus 78.1°±5.3°) ( P>0.05). Conclusions:Supramalleolar dome osteotomy has shown promising short-term clinical efficacy in the treatment of varus-type ankle arthritis. It can significantly relieve pain, improve function, substantially correct deformity and retard progression of arthritis, but it may affect dorsal extension.

ABSTRACT

Objective:To study the optimal pain control goal for preventing delirium in critical patients.Methods:A prospective cohort study were conducted. The patients admitted to general departments and transferred to the intensive care unit (ICU) due to critical illness in the First People's Hospital of Changde from January 2017 to November 2019 were enrolled. The General data of the patients were collected within 48 hours after admission. All patients admitted to the ICU were evaluated for pain level using the critical care pain observation tool (CPOT) every 8 hours by nurses, and confusion assessment method of ICU (CAM-ICU) was used to screen delirium patient every 8 hours by the leader of nursing team without knowing the pain level of the patients, until the subjects were transferred out of ICU. The receiver operating characteristic (ROC) curve was drawn, the area under ROC curve (AUC) and the optimal threshold were analyzed with delirium as the reference standard; according to the optimal threshold, multivariate Logistic regression analysis was used to evaluate the correlation between CPOT score and delirium.Results:During the study period, 575 patients were admitted to the participating departments and passed the preliminary screening according to the inclusion and exclusion criteria. During the study period, 34 patients were excluded due to incomplete data. Finally, a total of 541 patients were enrolled in the analysis, including 149 patients in delirium group and 392 patients in non-delirium group. There was no significant difference in gender, age, source of patients, education level, smoking history, drinking history, family mental history, acute physiology and chronic health evaluation Ⅱ (APACHEⅡ) score or other general information between the two groups. There were 10.1% (15/149) of patients in the delirium group used opioids, which was significantly higher than 4.3% (17/392) in the non-delirium group, and the difference was statistically significant ( P < 0.05). The CPOT score in the delirium group was significantly higher than that in the non-delirium group (4.24±1.78 vs. 2.75±1.95, P < 0.01). The patients were subdivided into young group (< 40 years old), middle-aged group (40-65 years old) and old group (> 65 years old) according to age. The analysis results were consistent with the overall analysis results. ROC curve analysis showed that the AUC of CPOT score predicting delirium was 0.719; when the best threshold value of CPOT score was 2.5, the sensitivity was 91.3%, the specificity was 49.0%, the positive predictive value was 40.5% and the negative predictive value was 93.7%. Multivariate Logistic regression analysis showed that the risk of delirium in ICU patients with CPOT score ≥ 3 was 10.043 times higher than that in patients with CPOT score < 3 [odds ratio ( OR) = 10.043, 95% confidence interval (95% CI) was 5.498-18.345, P < 0.001]. When the gender, age, APACHEⅡ score, smoking history, drinking history, opioids usage were adjusted, the risk of delirium in patients with CPOT score ≥ 3 was 10.719 times higher than that in patients with CPOT score < 3 ( OR = 10.719, 95% CI was 5.689-20.196, P < 0.001). Conclusion:The best pain control goal for preventing the occurrence of delirium in ICU patients is a CPOT score of 3 or less.

ABSTRACT

Clinical data of a child with acquired immunodeficiency syndrome characterized by ischemic stroke who was admitted to the Pediatric Intensive Care Unit of Children′s Hospital Affiliated to Soochow University in January 2019 were retrospectively analyzed.The child is a 6 years and 4 months old boy with a history of thrombocytopenic purpura and recurrent respiratory infections.The main complaint was " the right limb weakness for more than 10 days" . The head magnetic resonance imaging (MRI) revealed extensive abnormal signals in the bilateral frontal and parietal lobes and the formation of softening foci in the left thalamus and outer capsule.Blood routine showed white blood cell 4.88×10 9/L, lymphocyte ratio 0.291, lymphocyte count 1.42×10 9/L, hemoglobin 99 g/L, and platelet 23×10 9/L.Lymphocyte subsets included CD3 + 84.1%, CD3 + CD4 + 0.2%, CD3 + CD8 + 61.4%, CD4 + /CD8 + 0, CD3 -CD 19+ 9.2%, CD3 -CD 16+ 56+ 6.1%, and CD 19+ CD 23+ 5.8%.Pretransfusion tests suggested human immunodeficiency virus (HIV) (+ ), and that other results were negative.Both parents of the child were infected with HIV.This paper demonstrates that neurological involvement is not rare in HIV infection, and stroke is the most common cause of clinical focal neurological deficits in HIV-infected children.Screening with MRI is recommended for high-risk children with neurologic symptoms or neurocognitive dysfunction.

ABSTRACT

Objective:To study the pathogenic distribution of bronchoalveolar lavage fluid in children with severe pneumonia from Children′s Hospital Affiliated to Soochow University, and to investigate the drug resistance of major pathogenic bacteria.Methods:A total of 177 children with severe pneumonia undergoing fiberoptic bronchoscopy in Children′s Hospital Affiliated to Soochow University from January 2014 to December 2018 were enrolled.Their bronchoalveolar lavage fluid was collected for pathogen identification, pathogen culture and drug sensitivity analysis.The pathogens were detected by direct immunofluorescence quantitative PCR.Results:Of 177 cases enrolled, 100 children had at least one pathogen detected, and the positive rate was 58.13%.Among all the pathogens detected, Mycoplasma pneumonia (MP) had the highest detection rate, which was found in 41 cases.The top three bacteria detected included Streptococcus pneumoniae (9 cases, 10.59%), Staphylococcus aureus (8 cases, 9.41%), and Pseudomonas aeruginosa (6 cases, 7.06%). The top three viruses detected were cytomegalo virus (CMV) (14 cases, 33.33%), human bocavirus (HBoV) (10 cases, 23.81%), and respiratory syncytial virus (RSV) (8 cases, 19.05%). The drug sensitive test indicated that main kinds of Gram-negative bacteria had low resistance to quinolones, aminoglycosides, carbapenems, and enzymatic beta-lactams.Main kinds of Gram-positive bacteria had low resistance to Linezolid and vancomycin.The virus detection rate and MP detection rate in severe pneumonia children under 5 years old were about 30.00% and 20.00%, respectively.The MP detection rate in children above 5 years old exceeded 30.00%.The bacteria detection rates in children under and above 2 years old were over 20.00% and about 15.00%, respectively.Airway abnormalities were common in children with severe pneumonia, mainly including tracheobronchial malacia and stenosis. Conclusions:The most common pathogen of bronchoalveolar lavage fluid in severe pneumonia children under 5 years old in Suzhou is viruses.The bacteria detection rate is high in children under 2 years old.Common Gram-positive bacteria show high susceptibility to vancomycin and Linezolid. Pseudomonas aeruginosa is highly sensitive to quinolones, aminoglycosides, carbapenems, and enzymatic beta-lactams.Importance should be attached to the airway abnormalities in children, especially infants, with severe pneumonia.

ABSTRACT

BACKGROUND@#Shenyankangfu Tablet (SYKFT) is a Chinese patent medicine that has been used widely to decrease proteinuria and the progression of chronic kidney disease.@*OBJECTIVE@#This trial compared the efficacy and safety of SYKFT, for the control of proteinuria in primary glomerulonephritis patients, against the standard drug, losartan potassium.@*DESIGN, SETTING, PARTICIPANTS AND INTERVENTION@#This was a multicenter, double-blind, randomized, controlled clinical trial. Primary glomerulonephritis patients, aged 18-70 years, with blood pressure ≤ 140/90 mmHg, estimated glomerular filtration rate (eGFR) ≥ 45 mL/min per 1.73 m@*MAIN OUTCOME MEASURES@#The primary outcome was change in the 24-hour proteinuria level, after 48 weeks of treatment.@*RESULTS@#A total of 735 participants were enrolled. The percent decline of urine protein quantification in the SYKFT group after 48 weeks was 8.78% ± 2.56% (P = 0.006) more than that in the losartan 50 mg group, which was 0.51% ± 2.54% (P = 1.000) less than that in the losartan 100 mg group. Compared with the losartan potassium 50 mg group, the SYKFT plus losartan potassium 50 mg group had a 13.39% ± 2.49% (P < 0.001) greater reduction in urine protein level. Compared with the losartan potassium 100 mg group, the SYKFT plus losartan potassium 100 mg group had a 9.77% ± 2.52% (P = 0.001) greater reduction in urine protein. With a superiority threshold of 15%, neither was statistically significant. eGFR, serum creatinine and serum albumin from the baseline did not change statistically significant. The average change in TCM syndrome score between the patients who took SYKFT (-3.00 [-6.00, -2.00]) and who did not take SYKFT (-2.00 [-5.00, 0]) was statistically significant (P = 0.003). No obvious adverse reactions were observed in any group.@*CONCLUSION@#SYKFT decreased the proteinuria and improved the TCM syndrome scores of primary glomerulonephritis patients, with no change in the rate of decrease in the eGFR. SYKFT plus losartan potassium therapy decreased proteinuria more than losartan potassium therapy alone.@*TRIAL REGISTRATION NUMBER@#NCT02063100 on ClinicalTrials.gov.

ABSTRACT

OBJECTIVE@#To observe the changes of symptoms, Chinese medicine (CM) syndrome, and lung inflammation absorption during convalescence in patients with coronavirus disease 2019 (COVID-19) who had not totally recovered after hospital discharge and whether CM could promote the improvement process.@*METHODS@#This study was designed as a prospective cohort and nested case-control study. A total of 96 eligible patients with COVID-19 in convalescence were enrolled from Beijing Youan Hospital and Beijing Huimin Hospital and followed up from the hospital discharged day. Patients were divided into the CM (64 cases) and the control groups (32 cases) based on the treatment with or without CM and followed up at 14, 28, 56, and 84 days after discharge. In the CM group, patients received the 28-day CM treatment according to two types of CM syndrome. Improvements in clinical symptoms, CM syndrome, and absorption of lung inflammation were observed.@*RESULTS@#All the 96 patients completed the 84-day follow-up from January 21 to March 28, 2020. By the 84th day of follow-up, respiratory symptoms were less than 5%. There was no significant difference in the improvement rates of symptoms, including fatigue, sputum, cough, dry throat, thirst, and upset, between the two groups (P>0.05). Totally 82 patients (85.42%) showed complete lung inflammation absorption at the 84-day follow-up. On day 14, the CM group had a significantly higher absorption rate than the control group (P<0.05) and the relative risk of absorption for CM vs. control group was 3.029 (95% confidence interval: 1.026-8.940). The proportions of CM syndrome types changed with time prolonging: the proportion of the pathogen residue syndrome gradually decreased, and the proportion of both qi and yin deficiency syndrome gradually increased.@*CONCLUSIONS@#Patients with COVID-19 in convalescence had symptoms and lung inflammation after hospital discharge and recovered with time prolonging. CM could improve lung inflammation for early recovery. The types of CM syndrome can be transformed with time prolonging. (Registration No. ChiCTR2000029430).

ABSTRACT

OBJECTIVE@#To investigate the shared mechanisms of scutellarin in angina pectoris (AP) and ischemic stroke (IS) treatment.@*METHODS@#A network pharmacology approach was used to detect the potential mechanisms of scutellarin in AP and IS treatment by target prediction, protein-protein interaction (PPI) data collection, network construction, network analysis, and enrichment analysis. Furthermore, molecular docking simulation was employed to analyze the interaction between scutellarin and core targets.@*RESULTS@#Two networks were established, including a disease-target network and a PPI network of scutellarin targets against AP and IS. Network analysis showed that 14 targets, namely, AKT1, VEGFA, JUN, ALB, MTOR, ESR1, MAPK8, HSP90AA1, NOS3, SERPINE1, FGA, F2, FOXO3, and STAT1, might be the therapeutic targets of scutellarin in AP and IS. Among them, NOS3 and F2 were recognized as the core targets. Additionally, molecular docking simulation confifirmed that scutellarin exhibited a relatively high potential for binding to the active sites of NOS3 and F2. Furthermore, enrichment analysis indicated that scutellarin might exert a therapeutic role in both AP and IS by regulating several important pathways, such as coagulation cascades, mitogen-activated protein kinase (MAPK) signaling pathway, phosphatidylinositol 3 kinase (PI3K)/protein kinase B (Akt)/mammalian target of rapamycin (mTOR) signaling pathway, Toll-like receptor signaling pathway, hypoxia inducible factor-1 (HIF-1) signaling pathway, forkhead box O (FoxO) signaling pathway, tumor necrosis factor (TNF) signaling pathway, adipocytokine signaling pathway, insulin signaling pathway, insulin resistance, and estrogen signaling pathway.@*CONCLUSIONS@#The shared underlying mechanisms of scutellarin on AP and IS treatment might be strongly associated with its vasorelaxant, anticoagulant, anti-inflammatory, and antioxidative effects as well as its effect on improving lipid metabolism.

ABSTRACT

Pneumoconiosis, an interstitial lung disease that occurs from breathing in certain kinds of damaging dust particles, is a major occupational disease in China. Patients diagnosed with occupational pneumoconiosis can avail of free medical treatment, whereas patients without a diagnosis of occupational diseases cannot not claim free medical treatment in most provinces from the government before 2019. This study aimed to analyze the priority of medical facility selection and its influencing factors among patients with pneumoconiosis. A total of 1,037 patients with pneumoconiosis from nine provinces in China were investigated. The health service institutions most frequently selected by the patients were county-level hospitals (37.5%). The main reason for the choice was these hospitals' close distance to the patients' homes (47.3%). The factors for the choice of health care institutions were living in the eastern region (

ABSTRACT

BACKGROUND@#Colorectal cancer is harmful to the patient's life. The treatment of patients is determined by accurate preoperative staging. Magnetic resonance imaging (MRI) played an important role in the preoperative examination of patients with rectal cancer, and artificial intelligence (AI) in the learning of images made significant achievements in recent years. Introducing AI into MRI recognition, a stable platform for image recognition and judgment can be established in a short period. This study aimed to establish an automatic diagnostic platform for predicting preoperative T staging of rectal cancer through a deep neural network.@*METHODS@#A total of 183 rectal cancer patients' data were collected retrospectively as research objects. Faster region-based convolutional neural networks (Faster R-CNN) were used to build the platform. And the platform was evaluated according to the receiver operating characteristic (ROC) curve.@*RESULTS@#An automatic diagnosis platform for T staging of rectal cancer was established through the study of MRI. The areas under the ROC curve (AUC) were 0.99 in the horizontal plane, 0.97 in the sagittal plane, and 0.98 in the coronal plane.

ABSTRACT

OBJECTIVE@#To observe the analgesic effect of auricular point sticking therapy during the perioperative stage in the patients with partial lung resection.@*METHODS@#A total of 92 patients with partial lung resection were randomized into an auricular point group (31 cases, 1 case dropped off), the sham-auricular point group (30 cases) and a medication group (31 cases, 1 case dropped off). The routine medication for analgesia was provided in all of the three groups. In the auricular point group, 1 day before operation, the auricular point sticking therapy was applied at shenmen (TF@*RESULTS@#In 8, 16, 24, 48 h and 72 h after operation, VAS scores in the auricular point group were lower than those in the sham-auricular point group and the medication group separately (@*CONCLUSION@#Auricular point sticking therapy relieves perioperative pain, shortens analgesic time, releases anxious and depressive emotions and reduces postoperative adverse reaction in the patients with partial lung resection. The analgesic mechanism is probably related to the increase of plasma concentration of β-endorphin.

ABSTRACT

Background/Aims@#Accumulating evidence indicates that L-carnitine (LC) protects against multiorgan damage through its antioxidant properties and preservation of the mitochondria. Little information is available about the effects of LC on renal fibrosis. This study examined whether LC treatment would provide renoprotection in a rat model of unilateral ureteral obstruction (UUO) and in vitro. @*Methods@#Sprague-Dawley rats that underwent UUO were treated daily with LC for 7 or 14 days. The influence of LC on renal injury caused by UUO was evaluated by histopathology, and analysis of gene expression, oxidative stress, mitochondrial function, programmed cell death, and phosphatidylinositol 3-kinase (PI3K)/ AKT/forkhead box protein O 1a (FoxO1a) signaling. In addition, H2O2-exposed human kidney cells (HK-2) were treated with LC. @*Results@#LC treatment inhibited expression of proinflammatory and profibrotic cytokines, and was followed by a significant attenuation of tubulointerstitial inflammation and fibrosis. The increased oxidative stress caused by UUO was associated with mitochondrial dysfunction and excessive apoptosis and autophagy via PI3K/AKT/FoxO1a-dependent signaling, and this was abrogated by administration of LC. In H2O2-exposed HK-2 cells, LC decreased intracellular production of reactive oxygen species, and suppressed expression of profibrotic cytokines and reduced the number of apoptotic cells. @*Conclusions@#LC protects against the progression of tubulointerstitial fibrosis in an obstructed kidney.

ABSTRACT

Purpose@#The objective of this study was to define the learning curve required to attain satisfactory oncologic outcomes of cervical cancer patients who were undergoing open or minimally invasive surgery for radical hysterectomy, and to analyze the correlation between the learning curve and tumor size. @*Materials and Methods@#Cervical cancer patients (stage IA-IIA) who underwent open radical hysterectomy (n=280) or minimal invasive radical hysterectomy (n=282) were retrospectively reviewed. The learning curve was evaluated using cumulative sum of 5-year recurrence rates. Survival outcomes were analyzed based on the operation period (“learning period,” P1 vs. “skilled period,” P2), operation mode, and tumor size. @*Results@#The 5-year disease-free and overall survival rates between open and minimally invasive groups were 91.8% and 89.0% (p=0.098) and 96.1% and 97.2% (p=0.944), respectively. The number of surgeries for learning period was 30 and 60 in open and minimally invasive group, respectively. P2 had better 5-year disease-free survival than P1 after adjusting for risk factors (hazard ratio, 0.392; 95% confidence interval, 0.210 to 0.734; p=0.003). All patients with tumors < 2 cm had similar 5-year disease-free survival regardless of operation mode or learning curve. Minimally invasive group presented lower survival rates than open group when tumors ≥ 2 cm in P2. Preoperative conization improved disease-free survival in patients with tumors ≥ 2 cm, especially in minimally invasive group. @*Conclusion@#Minimally invasive radical hysterectomy required more cases than open group to achieve acceptable 5-year disease-free survival. When tumors ≥ 2 cm, the surgeon’s proficiency affected survival outcomes in both groups.

ABSTRACT

@#AIM: To analyze the effectiveness and influencing factors of phacoemulsification combined with intraocular lens(IOL)implantation in the treatment of primary angle-closure glaucoma(PACG). <p>METHODS: Clinical data of 75 patients(75 eyes)with PACG who received phacoemulsification and IOL implantation in our hospital from January 2017 to December 2018 were retrospectively analyzed. Postoperative intraocular pressure(IOP), best-corrected visual acuity(BCVA), changes of anterior segment and incidence of complications were counted. The patients were grouped by efficacy, and multivariate Logistic regression analysis was performed to analyze the risk factors influencing the effectiveness of phacoemulsification and IOL implantation in patients with PACG. <p>RESULTS: Postoperative IOP of patients with PACG was decreased while BCVA was increased, and there were statistically significant differences compared with those before operation(<i>P</i><0.05). Central anterior chamber depth(ACD), angle opening distance(AOD500), trabecular iris angle(TIA500)and angle recess area(ARA)were increased significantly compared with those before operation(<i>P</i><0.05). Multivariate Logistic regression analysis showed that chronic PACG and preoperative IOP were independent risk factors for efficacy of phacoemulsification and IOL implantation in patients with PACG(<i>P</i><0.05). <p>CONCLUSION: Phacoemulsification combined with IOL implantation has good efficacy and safety in the treatment of PACG. However, it is necessary to pay attention to preoperative IOP control. What's more, it should be carefully considered whether this operation is necessary for patients with chronic PACG.

ABSTRACT

Ulcerative colitis (UC) is a chronic non-specific inflammatory bowel disease, listed as a modern refractory disease by the World Health Organization, which is difficult to recover, whereas it is easy to be attacked repeatedly. UC pathogenesis is closely related to gut microbiota dysbiosis. The gut microbiota interacts with bile acids (BAs), short-chain fatty acids (SCFAs), tryptophan, and other metabolism, immune system, intestinal barrier, etc., which regulate each other and affect the occurrence and development of UC. The active ingredients of traditional Chinese medicine (TCM), single herb and its extracts, and formulae can effectively alleviate UC symptoms by regulating the diversity, structure, composition, and metabolites of gut microbiota. In this review, the TCM based on the regulation of gut microbiota in the treatment of UC and its related mechanism for nearly three years was summarized.
