17q12 microdeletion syndrome is a rare genetic disease,commonly characterized by newly occurring mutations,which can cause abnormalities of the urinary and reproductive tract,diabetes mellitus,neurological and psychiatric disorders and mild deformities.This article reports a case of 17q12 microdeletion syndrome with CRYBB2 gene missense mutation,combined with menstrual abnormalities,multiple cysts in both kidneys,hypomagnesemia,hyperuricemia,small pancreatic morphology and low pancreatic enzyme levels.

Immune checkpoint inhibitor(ICI)associated diabetes mellitus(DM)a rare specific type of diabetes,usually developed after the treatment of programmed cell death protein 1(PD-1)inhibitor or programmed cell death ligand 1(PD-L1)inhibitor.We reported 4 cases of DM after ICI use.These patients had a subacute onset,6 to 17 months after the first use of the drug,with diabetic autoantibodies negative.Pancreas atrophy was observed in one of them.All of the patients received treatment of insulin.

AIM: To observe the postoperative changes in macular morphological structure and blood flow density of patients with idiopathic macular epiretinal membrane(IMEM)by optical coherence tomography angiography(OCTA), and explore their correlation with visual acuity.METHOD: Prospective study. A total of 45 cases(45 eyes)with IMEM admitted to our hospital from January 2020 to July 2021 were included. The best corrected visual acuity(BCVA), central macular area thickness(CMT), foveal avascular zone(FAZ)area and changes in blood flow density of superficial capillary plexus(SCP)were observed at 1mo, 1, 3 and 6mo before and after operation.RESULT: The BCVA at 1wk after operation had no significant change compared with preoperative data(P>0.05), while it was improved at other time points(P<0.05). The CMT measured at 1wk after operation was thickened significantly(P<0.05), while it was significantly decreased at 1mo, 3mo and 6mo after operation(P<0.05). The FAZ area measured at 1wk and 1mo after operation had no significant change(P>0.05), while it was significantly enlarged at 3 and 6mo after operation(P<0.05). The SCP measured at 1wk, 1 and 3mo after operation had no significant change(P>0.05), while it was significantly decreased at 6mo after operation(P<0.05). BCVA measured at 3 and 6mo after operation was positively correlated with CMT(r=0.457, 0.615, P=0.032, 0.012).CONCLUSION: The visual acuity of patients with IMEM recovered quickly within 1mo after operation, and then it tended to be stable. However, the recovery of macular foveal morphology and blood flow distribution was slower than that of visual acuity, and there was no obvious correlation with visual acuity.

AIM: To evaluate the application of single-pass four-throw releasable suture drainage tube ligation technique in Ahmed glaucoma valve(AGV)implantation.METHODS: A total of 78 patients(78 eyes)with refractory glaucoma who underwent AGV implantation in the People's Hospital of Leshan from May 2020 to January 2022 were retrospectively analyzed. According to the treatment, the patients were divided into the modified AGV implantation group, with 43 patients(43 eyes)treated by modified AGV implantation, ligating the drainage tube with single-pass four-throw releasable suture, and the traditional AGV implantation group, with 35 patients(35 eyes)treated by traditional AGV implantation. Followed-up for 6mo, the intraocular pressure(IOP), success rate and complications were observed at 1d, 1 and 2wk and 1 and 6mo after operation.RESULTS: Postoperative IOP at all follow-up visits was significantly lower than that before surgery in both groups(all P<0.05). There was no significant difference in IOP between groups at all follow-up visits(all P>0.05). The incidence of shallow anterior chamber was 5% in the modified AGV implantation group and 23% in the traditional AGV implantation group at 1wk after surgery(P<0.05). At 6mo after operation, the overall success rate was 98% in modified AGV implantation group and 89% in the traditional AGV implantation group(P>0.05).CONCLUSION:During AGV implantation, ligation of drainage tube with single-pass four-throw releasable suture can effectively reduce IOP and reduce the incidence of shallow anterior chamber in early postoperative stage. Furthermore, the technique is safe and efficacious.

BACKGROUND: Although intensively studied in patients with cardiovascular diseases (CVDs), the prognostic value of diastolic blood pressure (DBP) has little been elucidated in patients with acute exacerbation of chronic obstructive pulmonary disease (AECOPD). This study aimed to reveal the prognostic value of DBP in AECOPD patients. METHODS: Inpatients with AECOPD were prospectively enrolled from 10 medical centers in China between September 2017 and July 2021. DBP was measured on admission. The primary outcome was all-cause in-hospital mortality; invasive mechanical ventilation and intensive care unit (ICU) admission were secondary outcomes. Least absolute shrinkage and selection operator (LASSO) and multivariable Cox regressions were used to identify independent prognostic factors and calculate the hazard ratio (HR) and 95% confidence interval (CI) for adverse outcomes. RESULTS: Among 13,633 included patients with AECOPD, 197 (1.45%) died during their hospital stay. Multivariable Cox regression analysis showed that low DBP on admission (<70 mmHg) was associated with increased risk of in-hospital mortality (HR = 2.16, 95% CI: 1.53-3.05, Z = 4.37, P <0.01), invasive mechanical ventilation (HR = 1.65, 95% CI: 1.32-2.05, Z = 19.67, P <0.01), and ICU admission (HR = 1.45, 95% CI: 1.24-1.69, Z = 22.08, P <0.01) in the overall cohort. Similar findings were observed in subgroups with or without CVDs, except for invasive mechanical ventilation in the subgroup with CVDs. When DBP was further categorized in 5-mmHg increments from <50 mmHg to ≥100 mmHg, and 75 to <80 mmHg was taken as reference, HRs for in-hospital mortality increased almost linearly with decreased DBP in the overall cohort and subgroups of patients with CVDs; higher DBP was not associated with the risk of in-hospital mortality. CONCLUSION: Low on-admission DBP, particularly <70 mmHg, was associated with an increased risk of adverse outcomes among inpatients with AECOPD, with or without CVDs, which may serve as a convenient predictor of poor prognosis in these patients.

【Objective】 To investigate the willingness of whole blood donors to donate apheresis platelets and analyze its influencing factors. 【Methods】 A total of 400 whole blood donors from Kunshan Blood Station and Leshan Blood Station from January to May, 2023 were surveyed by random sampling, and their willingness to donate apheresis platelets were analyzed by univariate analysis and binary logistic regression analysis. 【Results】 A total of 386 valid questionnaires were collected, with a recovery rate of 96.5%. Among the 386 whole blood donors, 177 were willing to donate apheresis platelets, accounting for 45.9%. Univariate analysis showed that gender, age, education level, blood donation times, average blood donation volume, adverse reactions to blood donation, understanding of platelets, and family members' attitude towards blood donation were the main factors affecting the willingness of whole blood donors to donate platelets, and binary logistic regression analysis showed that gender, age, blood donation times, average blood donation volume, understanding of platelets and family members' attitude towards blood donation were the main factors. 【Conclusion】 Targeted recruitment of whole blood donors should be conducted to recruit more apheresis platelet donors, so as to meet clinical demand of apheresis platelets.

【Objective】 To explore the technical methods and clinical efficacy of transvaginal or transrectal repair in the treatment of iatrogenic bladder fistula. 【Methods】 The clinical data of 7 cases of iatrogenic bladder fistula patients treated during 2016 and 2019 were retrospectively analyzed, including 6 cases of vesicovaginal fistula (VVF) and 1 case of vesicorectal fistula (VRF). The operation was conducted 3 to 10 months after the diagnosis of urinary fistula, and the vagina or rectum was fully cleaned before operation. Modified Latzko technique was employed to separate the gap between the bladder wall and vaginal or rectal wall along the fistula, the fistula scar was sharply removed, and the fistula, bladder wall, vaginal or intestinal wall, and vaginal or intestinal mucosa were sutured in layers. The urinary catheter was indwelled for 4 weeks. 【Results】 All 7 cases were successfully repaired at one procedure. No urine leakage was found after the urinary catheter was removed. There was no recurrence after 6 to 12 months of follow-up. 【Conclusion】 Selective application of the modified Latzko technique to repair iatrogenic urinary fistula through the natural lumen is an advantageous treatment scheme, which simplifies the operation and reduces trauma.

Objective To compare the value of Child-Pugh score, Model for End-Stage Liver Disease (MELD) score, MELD combined with serum sodium concentration (MELD-Na) score, CLIF Consortium Acute Decompensation (CLIF-C AD) score, and Freiburg index of post-transjugular intrahepatic portosystemic shunt (TIPS) survival (FIPS) score in predicting the survival of patients undergoing TIPS. Methods A retrospective analysis was performed for the clinical data of 447 patients with liver cirrhosis who underwent TIPS in several hospitals in southwest China, among whom there were 306 patients in the survival group and 62 in the death group. The scores of the above five models were calculated, and a survival analysis was performed based on these models. The independent samples t -test was used for comparison of normally distributed continuous data between groups, and the non-parametric Mann-Whitney U test was used for comparison of non-normally distributed continuous data between groups; the Pearson chi-square test was used for comparison of categorical data between groups; a multivariate Cox regression analysis was used for correction analysis of known influencing factors with statistical significance which were not included in the scoring models; the Kaplan-Meier method was used to evaluate the discriminatory ability of each model in identifying risks in the surgical population, and the log-rank test was used for analysis. The area under the receiver operating characteristic curve (AUC), C-index at different time points, and calibration curve were used to evaluate the predictive ability of each scoring model. Results Compared with the death group, the survival group had significantly lower age ( Z =2.884, P < 0.05), higher albumin ( t =3.577, P < 0.05), and Na + ( Z =-3.756, P < 0.05) and significantly lower proportion of patients with alcoholic cirrhosis ( χ 2 =22.674, P < 0.05), aspartate aminotransferase ( Z =2.141, P < 0.05), prothrombin time ( Z =2.486, P < 0.05), international normalized ratio ( Z =2.429, P < 0.05), total bilirubin ( Z =3.754, P < 0.05), severity of ascites ( χ 2 =14.186, P < 0.05), and scores of the five models (all P < 0.05). Survival analysis showed that all scoring models effectively stratified the prognostic risk of the patients undergoing TIPS. Comparison of the C-index of each scoring model at different time points showed that Child-Pugh score had the strongest ability in predicting postoperative survival, followed by MELD-Na score, MELD score, and CLIF-C AD score, and FIPS score had a relatively poor predictive ability; in addition, the prediction efficiency of each score gradually decreased over time. Child-Pugh score had the largest AUC of 0.832 in predicting 1-year survival rate after surgery, and MELD-Na score had the largest AUC of 0.726 in predicting 3-year survival rate after surgery, but FIPS score had a poor ability in predicting 1- and 3-year survival rates. Conclusion All five scoring models can predict the survival of patients with liver cirrhosis after TIPS and can provide effective stratification of prognostic risk for such patients. Child-Pugh score has a better ability in predicting short-term survival, while MELD-Na score has a better ability in predicting long-term survival, but FIPS score has a relatively poor predictive ability in predicting both short-term and long-term survival.

BACKGROUND: Intensive phototherapy (IPT) and exchange transfusion (ET) are the main treatments for extreme hyperbilirubinemia. However, there is no reliable evidence on determining the thresholds for these treatments. This multicenter study compared the effectiveness and complications of IPT and ET in the treatment of extreme hyperbilirubinemia. METHODS: This retrospective cohort study was conducted in seven centers from January 2015 to January 2018. Patients with extreme hyperbilirubinemia that met the criteria of ET were included. Patients were divided into three subgroups (low-, medium-, and high- risk) according to gestational week and risk factors. Propensity score matching (PSM) was performed to balance the data before treatment. Study outcomes included the development of bilirubin encephalopathy, duration of hospitalization, expenses, and complications. Mortality, auditory complications, seizures, enamel dysplasia, ocular motility disorders, athetosis, motor, and language development were evaluated during follow-up at age of 3 years. RESULTS: A total of 1164 patients were included in this study. After PSM, 296 patients in the IPT only group and 296 patients in the IPT plus ET group were further divided into the low-, medium-, and high-risk subgroups with 188, 364, and 40 matched patients, respectively. No significant differences were found between the IPT only and IPT plus ET groups in terms of morbidity, complications, and sequelae. Hospitalization duration and expenses were lower in the low- and medium-risk subgroups in the IPT only group. CONCLUSIONS In this study, our results suggest that IPT is a safe and effective treatment for extreme hyperbilirubinemia. The indication of ET for patients with hyperbilirubinemia could be stricter. However, it is necessary to have a contingency plan for emergency ET as soon as IPT is commenced especially for infants with risk factors. If IPT can be guaranteed and proved to be therapeutic, ET should be avoided as much as possible.
