Renal ischemia-reperfusion injury （RIRI） is a major cause of acute kidney injury during kidney transplantation and peri-operative settings， and there is still a lack of safe and effective targeted preventive and therapeutic drugs in clinical practice. Specifically， xanthohumol， luteolin， dracorhodin C， naringin， senkyunolide Ⅰ， verbascoside， and shikonin enhance antioxidant defenses， and inhibit lipid peroxidation and ferroptosis via the nuclear factor-erythroid 2-related factor 2/heme oxygenase-1 pathway. Apigenin， nobiletin， tanshinone Ⅱ A ， and salidroside activate the phosphatidylinositol 3-kinase/protein kinase B pathway to inhibit mitochondria- dependent apoptosis and facilitate renal repair. Quercetin， methyleugenol， cyanidin-3-glucoside， and platycodin D promote autophagy and improve mitochondrial homeostasis through the adenosine monophosphate-activated protein kinase（AMPK）/mTOR or AMPK/phosphatase and tensin homolog-induced kinase 1/Parkin pathways. In addition， hesperidin， curcumin， ganoderic acid， pulsatilla saponin B4， capsaicin， and diosgenin mitigate inflammatory responses and decrease renal tubular injury markers by inhibiting the Toll-like receptor 4/nuclear factor κB， high mobility group box 1， Janus kinase/signal transducer and activator of transcription pathways， thereby exerting multi-target， multi-stage renoprotective effects.

OBJECTIVES: To investigate the ethnic origin of Chuanqing people, one of the largest unidentified ethnic groups in Guizhou, China, and analyze its genetic relationships with surrounding populations. METHODS: Based on a self-developed microhaplotype system, we conducted genotyping and analyzed the genetic distribution of microhaplotype loci and their forensic applicability in Chuanqing population in Guizhou Province. Using the microhaplotype data from different intercontinental populations and previously reported data from Han population living in Guizhou Province, we systematically investigated the genetic background of Chuanqing people through population genetic approaches, including genetic distance estimation, principal component analysis, and phylogenetic tree construction. RESULTS: Among the studied population, the number of haplotype per microhaplotype ranged from 6 to 25. The average expected heterozygosity (He), observed heterozygosity (Ho), power of discrimination (PD), and probability of exclusion (PE) were 0.8291, 0.8301, 0.9387, and 0.6593, respectively. The cumulative power of discrimination (CPD) and cumulative probability of exclusion (CPE) for these 33 loci were 1-2.62×10^-41 and 1-7.64×10^-17, respectively. Population genetic analyses revealed that the Chuanqing population had close genetic relationships with the East Asian populations, especially the local Guizhou Han population, Beijing Han population and the Han populations living in southern China. CONCLUSIONS The 33 microhaplotypes exhibit high levels of genetic diversity in the Guizhou Chuanqing population, highlighting their potentials for both forensic identification and parentage testing. The Han populations might have contributed a significant amount of genetic material to the Chuanqing population during the formation and development of the latter.

Objective To investigate the value of Chinese Group on the Study of Severe Hepatitis B-acute-on-chronic liver failureⅡ(COSSH-ACLF Ⅱ)score in predicting the short-term prognosis of patients with hepatitis B virus-related acute chronic liver failure(HBV-ACLF)comorbid with hepatic encephalopathy(HE).Methods A retrospective analysis was performed for 134 patients who were admitted to The First Hospital of Shanxi Medical University from January 2019 to October 2024 and were diagnosed with HBV-ACLF and HE,and according to the survival status of the patients on day 90 of follow-up,they were divided into survival group with 60 patients and death group with 74 patients.Related scores were calculated,including COSSH-ACLF Ⅱ score,COSSH-ACLF score,Model for End-Stage Liver Disease(MELD)score,MELD combined with serum sodium concentration(MELD-Na)score,and MELD 3.0 score,and the two groups were compared in terms of basic clinical data,laboratory markers,complications,and the scores of each model.The chi-square test was used for comparison of categorical data between two groups,and the t-test or the Mann-Whitney U test was used for comparison of continuous data between two groups.The receiver operating characteristic(ROC)curve was used to assess the performance of each score in predicting the prognosis of patients with comorbidity of HBV-ACLF and HE.Results The death group had a significantly higher age than the survival group(56.09±10.52 years vs 49.23±11.57 years,t=2.720,P=0.007).Compared with the survival group,the death group had significantly higher incidence rate of complications(upper gastrointestinal bleeding and ascites)and laboratory markers(white blood cell count,neutrophil count,total bilirubin,international normalized ratio,serum creatinine,and blood urea nitrogen)(all P<0.05).The death group had significantly higher COSSH-ACLF Ⅱ,COSSH-ACLF,MELD,MELD-Na,and MELD 3.0 scores than the survival group(all P<0.001).The patients were stratified into low-,moderate-,and high-risk groups based on COSSH-ACLF Ⅱs score,and comparison between groups showed that the mortality rate of patients increased with the increase in COSSH-ACLF Ⅱ score(χ2=44.371,P<0.001).The ROC curve analysis showed that COSSH-ACLF Ⅱ score had an area under the ROC curve(AUC)of 0.883(95%confidence interval:0.837-0.919)in predicting the 90-day mortality of patients with comorbidity of HBV-ACLF and HE,with a sensitivity of 90.5%,a specificity of 78.7%,and a predictive accuracy of 85.07%at the cut-off value of 7.25.COSSH-ACLF Ⅱscore had a better performance than COSSH-ACLF(AUC=0.841,P<0.05),MELD 3.0(AUC=0.733,P<0.05),MELD-Na(AUC=0.723,P<0.05),and MELD(AUC=0.716,P<0.05).Conclusion COSSH-ACLF Ⅱ score can improve the accuracy of predicting 90-day prognosis in patients with comorbidity of HBV-ACLF and HE,and COSSH-ACLF Ⅱ risk stratification can help to simplify the grading of patients.

In surgical diagnosis and treatment,the perioperative period is a comprehensive diagnosis and treatment process,including the rational application of antibiotics,nutrition management,pain management,blood pressure,blood sugar man-agement,and other processes.Perioperative pharmaceutical care has become one of the innovative fields of pharmaceutical care.In order to ensure the work and service quality of perioperative pharmaceutical care,the preparation team of perioperative pharmaceu-tical care standards takes scientific,universal,and practical principles as the basic principles,reviews the key points and difficul-ties from the three aspects of relevant national policy documents,relevant domestic and foreign standards and norms,and literature analysis,and combines the actual situation of perioperative pharmaceutical care.This pharmaceutical care standard was formulated after several rounds of opinion solicitation and expert argumentation.This paper analyzes the key contents of the standard,inclu-ding the basic requirements,service process,quality control,and evaluation and improvement of perioperative pharmaceutical care,so as to provide reference suggestions for medical structure managers and pharmacists who carry out perioperative pharma-ceutical care to deeply understand and practice this standard,so as to improve perioperative pharmaceutical care.

Objective:To investigate the effect of DExH-box helicase 9(DHX9)O-linked N-acetylglucosamine(O-GlcNAc)modifi-cation(O-GlcNAcylation)on the proliferation of hepatitis B virus(HBV)-associated hepatoma cells.Methods:The pAdTrack-TO4-DHX9-3Flag recombinant adenovirus plasmid was constructed by molecular cloning and transfected into HEK293 cells for packaging and amplification of the recombinant adenovirus AdDHX9.The interaction between DHX9 and O-GlcNAc transferase(OGT)was con-firmed using co-immunoprecipitation.The co-localization between DHX9 and OGT was measured by immunofluorescence.The level of DHX9 O-GlcNAcylation was determined using succinylated wheat germ agglutinin(sWGA)and glycosylated immunoprecipitation(IP).The effect of DHX9 O-GlcNAcylation on the proliferation of HBV-associated hepatoma cells was assessed using the colony-forming assay and cell growth curves.Results:The recombinant adenovirus AdDHX9 was successfully obtained,and DHX9 expression was confirmed by Western blot.DHX9 interacted with OGT,and the two proteins were co-localized on the nucleus.The sWGA and gly-cosylated IP experiments showed that DHX9 underwent O-GlcNAcylation,which was further enhanced by HBV infection.The colony-forming assay demonstrated that the number of cell clones was increased in the AdDHX9 group(386.667±15.630)compared with the AdGFP control group(142.667±7.572,P<0.001).Moreover,cell growth curves demonstrated that the overall cell growth rate was en-hanced in the AdDHX9 group(22.860±0.770)compared with the AdGFP control group(13.670±0.517,P<0.001).Conclusion:HBV infection promotes DHX9 O-GlcNAcylation,which enhances the proliferation of HBV-associated hepatoma cells.

ObjectiveTo investigate the effect of video-based educational intervention combined with maternal presence on perioperative adverse outcomes in preschool children undergoing general anesthesia， including cooperation in anesthesia induction， perioperative anxiety， pain and agitation during recovery. MethodsA total of 300 preschool children scheduled for general anesthesia in our hospital from June to December 2023 were randomly assigned to control group （n=150） and intervention group （n=150）. The control group received routine recovery care. For the intervention group， in addition to routine recovery care， a preoperative visit was scheduled one day before surgery. During this visit， mothers were guided to watch anesthesia videos with their children. During the waiting period in the operating room and 30 minutes after awakening， the mothers were guided to accompany the children for more than 30 minutes. Recovery conditions were recorded using the surgical anesthesia information system， and the children’s anesthetic induction compliance， perioperative anxiety， pain， and agitation were evaluated and recorded using the modified Yale Preoperative Anxiety Scale （m-YPAS）， the Induction Compliance Scale （ICC）， the Children’s Pain Behavior Scale （FLACC）， and the Pediatric Agitation and Emergence Delirium Scale （PAED）. ResultsOn the preoperative visit day， there were no statistically significant differences in baseline data between the two groups （P > 0.05）. For perioperative anxiety， the m-YPAS scores of the intervention group were significantly lower than those of the control group， both when entering the operating room waiting area （35.27±6.48 vs. 41.79±6.68， P < 0.05） and 30 minutes after postoperative recovery （20.13±7.05 vs. 35.75±9.51， P < 0.05）. In terms of anesthesia induction cooperation， the ICC scores of the intervention group were significantly lower than those of the control group （1.84±0.95 vs. 3.17±0.62， P < 0.05）， and the proportion of good induction cooperation was significantly higher than that of the control group （24.00% vs. 12.67%， P < 0.05）. There was no significant difference in awakening duration between the two groups， but the intervention group had a significantly shorter length of stay in the post-anesthesia care unit than the control group （0.90±0.29 hours vs. 1.29±0.42 hours， P < 0.001）. For perioperative agitation， the PAED scores of the intervention group were significantly lower than those of the control group （entering in the operating room waiting area： 8.5 vs. 9.2， P < 0.05； 30 minutes after postoperative recovery： 4.2 vs. 7.8， P < 0.05）. In terms of pain scores， the FLACC scores of the intervention group were also significantly lower than those of the control group， both when entering the operating room waiting area （ 5.3 vs. 6.7， P < 0.05； 30 minutes after postoperative recovery： 2.1 vs. 4.9， P < 0.05）. ConclusionsVideo-based educational intervention combined with maternal presence reduces the perioperative anxiety， pain and agitation of preschool children undergoing general anesthesia， and improved the compliance of anesthesia induction. It is recommended to promote this intervention measure in clinical practice.

Objective To explore the feasibility and safety of ultrasound-guided percutaneous microwave ablation for unresectable pancreatic cancer.Methods Totally 84 patients who underwent ultrasound-guided percutaneous microwave ablation for unresectable pancreatic cancer were enrolled,and the technical success rate,complete ablation rate,complication rate,pain relief rate and survival time,etc.were observed.Results The median age of 84 cases was 61.5 years.Totally 86 tumors,including 44.19％(38/86)at the head/neck and 55.81％(48/86)at the body/tail of pancreas were detected,and a total of 85 ablation sessions were performed with the median ablation energy applied per tumor of 9.90(1.08,21.60)kJ and the complete ablation rate of 42.86％(36/84).The technical success rate was 100％(85/85).Thirty-nine complication events occurred in 25 cases,no ablation-related death.Among 34 patients underwent ablation mainly for pain symptoms,the pain score decreased from(6.22±1.12)points before treatment to(1.94±1.64)points after treatment(P＜0.001).During 6.8(3.3,12.9)months' follow-up,the mean survival time was(8.5±6.7)months,and all 47 patients died due to tumor progression.Conclusion Ultrasound-guided percutaneous microwave ablation was safe and feasible for unresectable pancreatic cancer.

Objective:To identify prognostic factors associated with survival rates in patients with distal cholangiocarcinoma after radical surgery, and to construct a Nomogram prediction model based on these factors, as well as to perform internal validation of the model.Methods:A retrospective study was conducted on the clinical data of 162 patients (76 males and 86 females) with distal cholangiocarcinoma who underwent radical surgery at the Department of Hepatobiliary Surgery, Ningxia Medical University General Hospital from January 2011 to July 2019. The study used univariate and multivariate Cox regression analysis to identify independent risk factors and constructed a Nomogram prediction model using R software version 4.4.1. Additionally, the predictive accuracy of the model was evaluated through the C-index, the area under the receiver operating characteristic curve, and the calibration curve.Results:The median overall survival for the 162 patients was 18.4 months. The final multivariate Cox regression analysis revealed that the following factors were independent risk factors for poor postoperative prognosis in patients with distal cholangiocarcinoma: patient age [> 60 years, P = 0.004, hazard ratios ( HR) = 1.876], tumor diameter (> 2.0 cm, P < 0.001, HR = 0.174), tumor differentiation degree [moderately differentiated/moderately to highly differentiated/highly differentiated, P = 0.017, HR = 1.407], lymph node metastasis (Yes, P = 0.002, HR = 0.551), and vascular invasion (Yes, P = 0.025, HR = 1.329) (all P < 0.05). Based on these independent risk factors identified through statistical analysis, the C-index of the constructed nomogram prediction model was 0.793. The area under the receiver operating characteristic curve values for the model predicting postoperative 1-year, 3-year, and 5-year overall survival rates were 0.932, 0.771, and 0.758,respectively. Conclusions:Patient age, tumor diameter, tumor differentiation degree, lymph node metastasis, and vascular invasion are independent risk factors for poor postoperative prognosis in patients with distal cholangiocarcinoma. The final Nomogram prediction model demonstrates good predictive ability and has certain practical application potential.
