Objective:To explore the relevancy between the uridine diphosphate-glucuronylgly-cosyltransferase 1A1 (UGT1A1) gene mutation and the phenotype of indirect hyperbilirubinemia in children.Methods:Sixteen cases with indirect hyperbilirubinemia who visited the Department of Gastroenterology, Children's Hospital of Nanjing Medical University from July 2013 to November 2019 were retrospectively analyzed and were divided into Gilbert syndrome (GS), Crigler-Najjar syndrome type II (CNS-II), and indirect hyperbilirubinemia groups unexplained by UGT1A1 gene mutations. The differences in gene mutation site information and general clinical data were compared. The association between gene mutation spectrum and bilirubin level was explored by t-test analysis.Results:Ten of the sixteen cases with indirect hyperbilirubinemia had GS, three had CNS-II, and three had indirect hyperbilirubinemia unexplained by UGT1A1 gene mutations. A total of six mutation types were detected, of which c.211G?>?A accounted for 37.5% (6/16), c.1456T?>?G accounted for 62.5% (10/16), and TATA accounted for 37.5% (6/16), respectively. Compared with the GS group, the CNS group had early disease onset incidence, high serum total bilirubin ( t ?=?5.539, P ??0.05) and age of onset ( t ?=?0.3611, P ?>?0.05) between the two groups. There was no significant correlation between the number of UGT1A1 gene mutations and serum bilirubin levels. Children with c.1456T?>?G homozygous mutations had the highest serum bilirubin levels. Conclusion:The common pathogenic variants of the UGT1A1 gene sequence are c.1456T?>?G, c.211G?>?A, and TATA, indicating that these site mutations are related to the occurrence of indirect hyperbilirubinemia and have important guiding significance for the etiological analysis of indirect hyperbilirubinemia in children.

Objective:To assess the treatment outcomes of endoscopic ultrasound-guided biliary drainage (EUS-BD) in patients with obstructive jaundice due to unsuccessful endoscopic retrograde cholangiopancreatography (ERCP).Methods:The clinical data of patients with obstructive jaundice who underwent EUS-BD due to ERCP failure at the Gastrointestinal Endoscopy Center of Beijing Friendship Hospital from September 2018 to November 2023, was retrospectively collected and analyzed. We explored the technical success, clinical success, and adverse events associated with EUS-BD.Results:In total, 43 EUS-BD procedures were performed in 39 patients with a technical success rate of 86.0% (37/43). The clinical success rate was 81.1% (30/37). Biliary drainage was not effectively achieved in seven cases, including two fatal cases and five cases of recurrent postoperative biliary obstruction. The incidence of adverse events was 21.6% (8/37), including two cases of postoperative bile leakage peritonitis, two cases of stent displacement, one case of stent dislocation, one case of perforation, and two cases of death.Conclusion:EUS-BD is a relatively safe and effective method for bile duct drainage, serving as a dependable alternative therapeutic option for patients with obstructive jaundice due to unsuccessful ERCP.

OBJECTIVE： To re-evaluate t he methodology quality of published systematic review/Meta-analysis of antidepressants in the treatment of post-stroke depression. METHODS ：Retrieved from Cochrane Library ，PubMed，Embase， SinoMed，CNKI，Wanfang database ，VIP，CBM and other databases ，systematic review/Meta-analysis of antidepressants in the treatment of post-stroke depression were collected during the inception to Dec. 2019. After literature screening and data extraction ， methodology quality of included literatures were evaluated by using the AMSTAR scale. RESULTS ：A total of 33 systematic reviews/Meta-analysis were included ，involving 523 RCTs and 41 020 patients. Average score of AMSTAR methodological quality evaluation was 6.76. Citalopram ，duloxetine and paroxetine were effective for the therapy of post-stroke depression ，but the conclusions about the effectiveness among antide-pressants were not consistents. The ADR incidence of Paroxetine was low. It was not clear that sertraline and citalopram may improve the neurological function of patients. CONCLUSIONS ：The methodological quality of systematic review/Meta-analysis of antidepressants in the treatment of post-stroke depression is medium ，and the conclusions about the effectiveness of antidepressants ，improvement of daily life ability and the recovery of neurological function are still controversial.

Objective:To explore the application value of sevoflurane inhalation anesthesia in mitral valve replacement.Methods:A total of 94 patients who underwent mitral valve replacement in our hospital (October 2016-October 2018) were randomly divided into the control group ( n=47) and the observation group ( n=47). The control group received target-controlled infusion of propofol, and the observation group inhaled sevoflurane.The postoperative conditions [intensive care unit (ICU) stay time, extubation time of tracheal tube, spontaneous cardiac rebound], hemodynamic indexes [mean arterial pressure (MAP), heart rate (HR)], serum creatine phosphokinase isoenzyme (CK-MB), cardiac troponin I (cTnI), malondialdehyde (MDA) and superoxide dismutase (SOD) in the two groups were analyzed. The patients were followed up for one month. The incidence of major adverse cardiovascular events (MACE) was calculated. Results:⑴ Postoperative situation: the time of stay in ICU and extubation of tracheal tube in the observation group was shorter than that in the control group, and the rate of spontaneous cardiac rebound (93.62%) was higher than that in the control group (72.34%) ( P<0.05); ⑵ Hemodynamic index level: there was no statistically significant difference in MAP and HR levels between two groups before operation, before cardiopulmonary bypass, after cardiopulmonary bypass, and after operation ( P>0.05); ⑶ CK-MB and cTnI: the levels of serum CK-MB and cTnI in the two groups were higher at 2, 6, 24, and 48 h after aortic cross-clamp release than before anesthesia induction, but the indicators of the observation group were lower than those in the control group; ⑷ MDA and SOD: the serum SOD level in the two groups at 2, 6, 24, and 48 h after aortic cross-clamp release were lower than before anesthesia induction, and the MDA level in the two groups at 2, 6, 24, and 48 h after aortic cross-clamp release were higher than before anesthesia induction. The level of SOD in the observation group was higher than that in the control group, and the level of MDA was lower than that in the control group ( P<0.05); ⑸ MACE: the incidence of MACE in the observation group (12.77%) was lower than that of the control group (29.79%) ( P<0.05). Conclusions:During mitral valve replacement, sevoflurane inhalation anesthesia can maintain hemodynamic stability. The duration of ICU stay and tracheal tube extubation time is shorter, and the fluctuation of serum CK-MB, cTnI, MDA and SOD is small, and it can reduce the risk of MACE.
