Laparoscopic subtotal cholecystectomy (LSC) has been a safe and viable alternative to conversion to laparotomy in cases of severe cholecystitis. The objective of this study is to determine the utility of intraoperative choledochoscopy in LSC for the exploration of the gallbladder, cyst duct, and subsequent stone clearance of the cystic duct in cases of severe cholecystitis. A total of 72 patients diagnosed with severe cholecystitis received choledochoscopy-assisted laparoscopic subtotal cholecystectomy (CALSC). A choledochoscopy was performed to explore the gallbladder cavity and/or cystic duct, and to extract stones using a range of techniques. The clinical records, including the operative records and outcomes, were subjected to analysis. No LSC was converted to open surgery, and no bile duct or vascular injuries were sustained. All stones within the cystic duct were removed by a combination of techniques, including high-frequency needle knife electrotomy, basket, and electrohydraulic lithotripsy. A follow-up examination revealed the absence of residual bile duct stones, with the exception of one common bile duct stone, which was extracted via endoscopic retrograde cholangiopancreatography. In certain special cases, CALSC may prove to be an efficacious treatment for the management of severe cholecystitis. This technique allows for optimal comprehension of the situation within the gallbladder cavity and cystic duct, facilitating the removal of stones from the cystic duct and reducing the residue of the non-functional gallbladder remnant.

Objective To investigate the incidence rate,clinical characteristics,and prognosis of neonatal stroke in Shenzhen,China.Methods Led by Shenzhen Children's Hospital,the Shenzhen Neonatal Data Collaboration Network organized 21 institutions to collect 36 cases of neonatal stroke from January 2020 to December 2022.The incidence,clinical characteristics,treatment,and prognosis of neonatal stroke in Shenzhen were analyzed.Results The incidence rate of neonatal stroke in 21 hospitals from 2020 to 2022 was 1/15 137,1/6 060,and 1/7 704,respectively.Ischemic stroke accounted for 75％(27/36);boys accounted for 64％(23/36).Among the 36 neonates,31(86％)had disease onset within 3 days after birth,and 19(53％)had convulsion as the initial presentation.Cerebral MRI showed that 22 neonates(61％)had left cerebral infarction and 13(36％)had basal ganglia infarction.Magnetic resonance angiography was performed for 12 neonates,among whom 9(75％)had involvement of the middle cerebral artery.Electroencephalography was performed for 29 neonates,with sharp waves in 21 neonates(72％)and seizures in 10 neonates(34％).Symptomatic/supportive treatment varied across different hospitals.Neonatal Behavioral Neurological Assessment was performed for 12 neonates(33％,12/36),with a mean score of(32±4)points.The prognosis of 27 neonates was followed up to around 12 months of age,with 44％(12/27)of the neonates having a good prognosis.Conclusions Ischemic stroke is the main type of neonatal stroke,often with convulsions as the initial presentation,involvement of the middle cerebral artery,sharp waves on electroencephalography,and a relatively low neurodevelopment score.Symptomatic/supportive treatment is the main treatment method,and some neonates tend to have a poor prognosis.

Objective To explore the associations of parental smoking and alcohol consumption during the periconceptional period and their interactions with risk of congenital heart disease(CHD)in offspring.Methods The parents of children with simple CHD aged 0 to 1 year(n=683)were recruited as the case group,while the parents of healthy children aged 0 to 1 year(n=740)served as the control group.A case-control study was conducted,and a questionnaire was used to collect information on perinatal exposures.After controlling for relevant confounding factors using multivariate logistic regression analysis and propensity score matching,the associations of parental smoking and alcohol consumption during the periconceptional period and their interactions with CHD were examined,as well as the cumulative effects of smoking and drinking on CHD risk.Results Maternal active smoking(OR=2.91,95%CI:1.60-5.30),passive smoking(OR=1.94,95%CI:1.56-2.42),and alcohol consumption(OR=2.59,95%CI:1.89-3.54),as well as paternal smoking(OR=1.52;95%CI:1.22-1.90)and drinking(OR=1.48,95%CI:1.19-1.84),were associated with an increased risk of CHD in offspring.There was no interaction between parental smoking and drinking behaviors during the periconceptional period concerning the risk of CHD in offspring(P>0.05).The more parents'smoking and drinking behaviors during the perinatal pregnancy,the higher the risk of CHD in their offspring(OR=1.50,95%CI:1.36-1.65).Conclusions Parental smoking and alcohol consumption during the periconceptional period are associated with the occurrence of CHD in offspring,and there is a cumulative effect on CHD risk,suggesting that reducing tobacco and alcohol exposure during the periconceptional period may lower the incidence of CHD.

Aim To investigate the dynamic changes of neuronal cells at different time points following acute cerebral ischemia-reperfusion injury by establishing a model of brain ischemia-reperfusion injury.Methods Thirty male Sprague-Dawley(SD)rats were ran-domly divided into six groups:sham group and cere-bral ischemia-reperfusion injury(IR)groups at differ-ent time points.Focal cerebral ischemia-reperfusion injury model was established using the middle cerebral artery occlusion(MCAO)technique.The Longa sco-ring method was used to assess neurobehavioral scores in rats.After successful model preparation,routine paraffin sections were made,and TUNEL staining and immunohistochemistry staining with NeuN antibody were performed to observe cell apoptosis and neuronal cell survival,respectively.Immunohistochemistry stai-ning was also performed to investigate the changes in glial fibrillary acidic protein(GFAP)as a marker for astrocytes,ionized calcium-binding adapter molecule 1(IBA-1)as a marker for microglia,and CD31 as a marker for endothelial cells at different time points.Results No significant changes were observed in neu-ronal cells of the sham group at different time points.In the cerebral ischemia-reperfusion injury groups,cell apoptosis was activated at IR3h and increased in quan-tity with morphological damage as time progressed.Ne-uN+neurons showed signs of ischemic injury after IR3h,with abnormal cell morphology.From 12 h,Ne-uN+neurons decreased in a time-dependent manner and reached their peak severity at 24 h.GFAP+astro-cytes decreased significantly after IR3h,while poorly labeled GFAP+astrocytes increased at IR 6 h and al-most disappeared in the infarcted area at 24 h and 48 h.The number of IBA-1+microglia-positive cells de-creased at IR3h,and their volume increased at IR6h.Microglial cell death was observed in the infarcted area at IR12h.CD31+endothelial cells around the infarc-ted cortex and striatum increased significantly after IR3h and persisted until 48 h.Conclusions After cerebral ischemia-reperfusion injury,the number of ap-optotic cells increases with the prolongation of time,and NeuN+neurons exhibit the most severe damage at 24 h.GFAP+astrocytes and microglial cells gradually die over time.The number of CD31+endothelial cells increases significantly around the infarcted cortex and striatum after 3 h of reperfusion and persists until 48 h.

Immune checkpoint inhibitors (ICIs) have ushered in a new era of tumor treatment; however, immunotherapy-related adverse events are critical issues that restrict the clinical application of ICIs and have attracted wide attention. The liver is one of the target organs that is easily affected. With the progress in research, scholars have found that besides hepatocytes, intrahepatic and extrahepatic bile ducts can also be attacked by the immune system, leading to the disease known as immune-related cholangitis. This article reviews the research advances in ICI-related cholangitis by summarizing related articles, in order to preliminarily reveal its clinical, pathological, and imaging features and provide clues for early identification, standard treatment, and subsequent research.

Food-dependent, exercise-induced anaphylaxis (FDEIA) is a potentially life-threatening disorder that often occurs with exercise, and patients typically have eaten a specific food within hours before disease onset. This disease is exceedingly rare, with a prevalence of 0.02%. No well-recognized prevention or treatment strategy has been available for FDEIA except avoiding triggers strictly. Here we report an 11-year-old boy with a history of recurrent anaphylaxis of unknown etiology more than 10 times within two years. As the anaphylactic symptoms had not been controlled after traditional treatments, the patient was given subcutaneous injection of dupilumab seven times within 33 weeks. During dupilumab treatments, the patient was exposed to culprit mushrooms plus exercises at least twice a month but without notable anaphylaxis. Thus, Dupilumab may improve the allergic reactions in FDEIA patients.

OBJECTIVE: To investigate the efficacy and safety of matched sibling donor allogeneic hematopoietic stem cell transplantation (allo-HSCT) in the treatment of young patients with multiple myeloma (MM). METHODS: The clinical data of 8 young patients (median age：46 years) with MM who underwent allo-HSCT from HLA-indentical sibling donors in the First Affiliated Hospital of Chongqing Medical University from June 2013 to September 2021 were collected, and their survival and prognosis were retrospectively analyzed. RESULTS: All the patients were successfully transplanted, and 7 patients could be evaluated the efficacy after transplantation. The median follow-up time was 35.2 (2.5-84.70) months. The complete response (CR) rate was 2/8 before transplantation and 6/7 after transplantation. Acute GVHD developed in 2 cases and extensive chronic GVHD developed in 1 case. Within 100 days, 1 case died of non-recurrent events, and 1-year and 2-year disease-free survival were 6 and 5 cases, respectively. At the end of follow-up, all the 5 patients who survived for more than 2 years survived, and the longest disease-free survival time has reached 84 months. CONCLUSION With the development of new drugs, HLA-matched sibling donor allo-HSCT may be a curable treatment for young patients with MM.
