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 explore the application effect and safety of general anesthesia with different doses of remimazolam during vascular intervention anesthesia of intracranial aneurysms.Methods Patients with intracranial aneurysms were divided into high,middle and low dose groups according to the random number table method.The venous access was opened after the patients entered the room,and the vital signs were closely monitored.The low,middle and high dose groups were intravenously injected with 0.25,0.30 and 0.35 mg·kg-1remazolam,respectively.After the loss of consciousness,alfentanil and mivacurium chloride were given for anesthesia induction.The anesthetic effect,recovery quality,hemodynamic indexes,cerebral hemodynamic indexes and neurological function indexes before anesthesia induction(T0),at the time of laryngeal mask insertion(T1),embolization(T2),5 min after operation(T3)and 30 min after operation(T4)were compared among the three groups.The incidence of postoperative cerebral vasospasm(CVS),delayed ischemic neurological dysfunction(DIND)and the incidence of adverse drug reactions related to anesthesia were counted.Results The onset times of anesthesia in the high,middle,and low dose groups were(5.03±1.28),(5.17±1.09),and(7.21±1.15)min,respectively;the number of anesthesia rescue interventions were(0.12±0.02),(0.21±0.06),and(1.51±0.23)times,respectively.There was statistically significant difference in the number of rescue interventions between the high and middle dose groups compared to the low dose group(all P＜0.05).The therapeutic efficacy rates of flumazenil in the high,middle,and low dose groups were 18.18％,11.11％and 2.86％,respectively.the mean arterial pressure(MAP)at T2 were(87.06±6.02),(86.85±5.61)and(81.09±5.37)mmHg;the MAP at T4 were(92.05±5.13),(87.57±6.29)and(84.42±5.16)mmHg,respectively.There was statistically significant difference in MAP between the high and low dose groups(all P＜0.05).There were no statistically significant differences in heart rate(HR),oxygen saturation(SpO2),left peak systolic velocity of middle cerebral artery(Vp-MCA),left mean systolic velocity of middle cerebral artery(Vm-MC)and pulsatility index(PI),S100β protein,and neuron-specific enolase(NSE)levels among the three groups at different time points(all P＞0.05).There were no statistically significant differences in the incidence rates of cardiovascular system complications,delayed postoperative cognitive dysfunction,or anesthesia-related adverse reactions between the three groups(all P＞0.05).Conclusion The safety of different doses of remimazolam general anesthesia in the vascular interventional therapy of intracranial aneurysms is high,and the effects on cerebral hemodynamics and neurological function are similar.However,high-dose remimazolam have shorter general anesthesia induction time and less intraoperative anesthesia remedy frequency while the high-dose remimazolam has higher postoperative flumazenil antagonist therapy.

As an important synthetic antibacterial drug, sulfonamides play an important role in the anti-infection field. Based on the research and development status of sulfonamides, this paper broke the classical structure of sulfanilamide, and designed and synthesized a series of acetyl-contained sulfanilamide tertiary amine thiol azole compounds and sulfanilamide tertiary amine amino azole compounds. The structures were confirmed by ¹H NMR, ¹³C NMR and HRMS. The antimicrobial activity of synthesized compounds in vitro was tested. The antimicrobial activity of amino triazole compound 7a gave stronger activity against Pseudomonas aeruginosa than that of positive control drug norfloxacin, and its inhibitory activity against Staphylococcus aureus was close to that of norfloxacin. The interaction between compound 7a and calf thymus DNA was studied, and the docking experiment between this compound and DNA was also researched.

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 systematically evaluate the incidence of healthcare-associated infection(HAI)in adult cases with carbapenem-resistant Enterobacterales(CRE)colonization in intestine,and provide referential basis for the prevention and control of HAI in cases colonized with CRE intestinally.Methods Literatures on the incidence of HAI in cases with intestinal CRE colonization were retrieved from 8 databases,including Embase,Cochrane,PubMed,Web of Science,CNKI,Wanfang,VIP,and China Biomedical Literature Database(CBM),dating back from the establishment of the databases to June 2023.Meta-analysis was conducted by Stata 17.0 software.Stabili-ty of the research results was evaluated by sensitivity analysis,and publication bias was evaluated by Egger's test.Results A total of 16 articles were included in the study,with in total 2 151 cases from 5 Chinese articles and 11 English articles.Meta-analysis results showed that the incidence of HAI in adult cases with intestinal CRE coloniza-tion was 23.1％(95％CI:14.8％-32.5％).Subgroup analysis was conducted based on grouping factors,such as different research design types,publication years,as well as research regions,departments,and infection sites.The differences in the combined effects among subgroups were not statistically significant(all P＞0.05).Among the CRE developed from colonization to HAI,the proportion of carpabenem-resistant Klebsiella pneumoniae(CRKP)was 96.0％(95％CI:86.8％-100％),and the incidence of bloodstream infection in colonized cases was 18.2％(95％CI:10.3％-27.6％).The 30-day mortality of CRE colonized cases was 32.6％(95％CI:20.5％-45.9％),and the 30-day mortality of CRE infected cases was 36.9％(95％CI:16.0％-60.2％).Conclusion In recent years,the incidence of HAI in cases with CRE colonization is high,it is necessary to actively screen and focus on intervention in high-risk departments,so as to decrease the incidence of HAI in CRE colonized cases.

AIM: To investigate the changes in retinal nerve fiber layer(RNFL)and macular retinal thickness(MRT)in children with refractive abnormalities and amblyopia, and their predictive value of outcome.METHODS: A total of 168 children with myopic refractive abnormalities and monocular amblyopia admitted to our hospital from January 2020 to October 2022 were selected as the observation group, with 118 cases of mild to moderate amblyopia and 50 cases of severe amblyopia, and 168 children with normal vision were included as the control group in a 1:1 ratio during the same period. The changes of RNFL and MRT in two groups of children were statistically counted, and the correlation between the severity of refractive abnormalities and RNFL and MRT in children with amblyopia was analyzed. Additionally, the observation group was divided into effective subgroup and ineffective subgroup based on the therapeutic effect. The general information, as well as RNFL and MRT of the effective subgroup and the ineffective subgroups before and after treatment were compared. Logistic was used to analyze the factors influencing efficacy, and ROC curves was plotted to analyze the predictive value of RNFL and MRT alone or in combination for efficacy.RESULTS: RNFL and MRT of cases of severe amblyopia were higher than those of the mild to moderate amblyopia and the control groups(all P<0.05); the severity of amblyopia in children with refractive abnormalities is positively correlated with RNFL and MRT(rs=0.745 and0.724, both P<0.001); among patients of mild to moderate and severe, there were statistically significant differences between the effective and ineffective subgroups in terms of initial treatment age, fixation form, treatment compliance, as well as RNFL, MRT, and their differences before and 1mo postoperatively(all P<0.05). Logistic analysis showed that initial treatment age, fixation nature, treatment compliance, RNFL and MRT before and 1mo postoperatively were all factors influencing the therapeutic effect of amblyopia with refractive abnormalities in children(all P<0.05); after 1mo of treatment, the combined prediction of RNFL and MRT was significantly better than that of single prediction in children with mild to severe amblyopia.CONCLUSION:There are differences in RNFL and MRT in children with abnormal refractive amblyopia, and they are closely related to the different degrees and curative effects of children. The combination of RNFL and MRT after 1mo of treatment has certain value in predicting children with different degrees of abnormal refractive amblyopia.

Purpose: Gastric cancer (GC) is the second most lethal cancer globally and is associated with poor prognosis. Fatty acid-binding proteins (FABPs) can regulate biological properties of carcinoma cells. FABP5 is overexpressed in many types of cancers; however, the role and mechanisms of action of FABP5 in GC remain unclear. In this study, we aimed to evaluate the clinical and biological functions of FABP5 in GC. Materials and Methods: We assessed FABP5 expression using immunohistochemical analysis in 79 patients with GC and evaluated its biological functions following in vitro and in vivo ectopic expression. FABP5 targets relevant to GC progression were determined using RNA sequencing (RNA-seq). Results: Elevated FABP5 expression was closely associated with poor outcomes, and ectopic expression of FABP5 promoted proliferation, invasion, migration, and carcinogenicity of GC cells, thus suggesting its potential tumor-promoting role in GC. Additionally, RNA-seq analysis indicated that FABP5 activates immune-related pathways, including cytokinecytokine receptor interaction pathways, interleukin-17 signaling, and tumor necrosis factor signaling, suggesting an important rationale for the possible development of therapies that combine FABP5-targeted drugs with immunotherapeutics. Conclusions These findings highlight the biological mechanisms and clinical implications of FABP5 in GC and suggest its potential as an adverse prognostic factor and/or therapeutic target.
