ObjectiveTo investigate the feasibility and safety of endoscopic retrograde cholangiopancreatography （ERCP） combined with oral cholangiopancreatography in the treatment of major duodenal papilla gallbladder polyps. MethodsA retrospective analysis was performed for the clinical data of eight patients with choledocholithiasis and gallbladder polyps who underwent ERCP and combined with oral cholangiopancreatography for major duodenal papilla cholecystectomy in Center of Digestive Endoscopy， Jilin People’s Hospital， from May 2022 to June 2024， and related data were collected， including the success rate of surgery， the technical success rate of gallbladder polyp removal， the superselective method of cystic duct， the time of operation， the time of gallbladder polyp removal， and surgical complications. ResultsBoth the success rate of surgery and the technical success rate of gallbladder polyp removal reached 100%， and of all eight patients， three patients used guide wire to enter the gallbladder under direct view， while five patients received oral cholangiopancreatography to directly enter the gallbladder. The time of operation was 51.88±12.34 minutes， and the time of gallbladder polyp removal was 23.13±10.94 minutes. The diameter of gallbladder polyp was 2‍ ‍—‍ ‍8 mm， and pathological examination showed inflammatory polyps in three patients， adenomatous polyps in one patient， and cholesterol polyps in four patients. There were no complications during or after surgery. The patients were followed up for 2‍ ‍—‍ ‍27 months after surgery， and no recurrence of gallbladder polyp was observed. ConclusionOral cholangiopancreatography is technically safe and feasible in endoscopic major duodenal papilla cholecystectomy.

Objective: To investigate the mechanism of electroacupuncture (EA) for treating depression and to explore the role of brevican in the medial prefrontal cortex (mPFC) in modulating stress susceptibility and the antidepressant effects of EA in rats. Methods: Twenty-four Sprague–Dawley (SD) rats were equally divided into three groups: green fluorescent protein (GFP) + control, GFP + chronic unpredicted mild stress (CUMS), and short-hairpin RNA targeting on brevican (shBcan) + CUMS. Another 24 SD rats were equally divided into CUMS + GFP, CUMS + GFP + EA, and CUMS + shBcan + EA groups. Behavioral tests were conducted to assess depression-like behavior. Western blot analysis was used to evaluate the expression of brevican, aggrecan, GLuA1, and PSD95 in mPFC subregions. Results: Behavioral parameter evaluation show that rats in the shBcan + CUMS group exhibited a significantly reduced sucrose preference (P = .0002) and increased immobility time (P = .0011) compared to those in rats in the GFP + CUMS group. Western blotting showed that brevican expression was significantly downregulated in the PrL of the shBcan + CUMS group compared with that in the GFP + CUMS group (P = .0192). Furthermore, compared to the CUMS + GFP + EA group, the CUMS + shBcan + EA group exhibited a significantly decreased sucrose preference (P = .0334), increased immobility time (P = .0465), and increased latency to food (P = .0261). In the CUMS + shBcan + EA group, the EA-induced brevican and PSD95 overexpression was reversed, compared with that in the CUMS + GFP + EA group (P = .0454 and P = .0198, respectively). Conclusion EA exerts its antidepressant effects through the modulation of brevican expression in rats. Our findings highlight the important role for brevican in stress susceptibility, which could be a potential target for treating depression.

Objective:To explore the clinical and genetic features of two Chinese pedigrees affected with Autosomal dominant intellectual developmental disorder 49 (MRD49).Methods:Two MRD49 pedigrees which were admitted to the Children′s Hospital Affiliated to Shandong University respectively on January 28, 2021 and November 10, 2022 were selected as the study subjects. Clinical data of the two pedigrees were collected and analyzed. Genomic DNA was extracted from peripheral blood samples of the probands and their family members. The probands were subjected to mutational analysis by high-throughput sequencing. Candidate variants were validated using real-time fluorescence quantitative PCR (q-PCR) or Sanger sequencing and bioinformatic analysis. This study was approved by the Medical Ethics Committee of the Children′s Hospital Affiliated to Shandong University (No. SDFE-IRB/T-2022002).Results:Proband 1 had presented with language delay, motor retardation and intellectual disability, and his maternal grandmother, mother, aunt and cousin all had various degrees of intellectual disability. Sequencing results showed that proband 1 had deletion of exons 3 ~ 7 of the TRIP12 gene. q-PCR verification showed that his mother, aunt, maternal grandmother and cousin had all harbored the same deletion. Based on the guidelines from the American College of Medical Genetics and Genomics (ACMG), the variant was classified as pathogenic (PVS1+ PM2_Supporting+ PP1). Proband 2, who had mainly presented with language delay, motor retardation and intellectual disability, and was found to harbor a heterozygous c.3010C>T (p.Arg1004*) variant of the TRIP12 gene, which was verified to be de novo in origin. Based on the guidelines from the ACMG, the variant was classified as pathogenic (PVS1+ PS2+ PM2_Supporting). Conclusion:This study had diagnosed two MRD49 families through high-throughput sequencing. Above findings have enriched the phenotypic and mutational spectrum of MRD49 in China, which has also facilitated genetic counseling for the two pedigrees.

Objective:To explore the predictive value of intraoperative cerebral oxygen satu-ration(rSO2)combined with serum chitinase-3-like protein 1(CHI3L1)and CXC-chemokine ligand 16(CXCL16)for postoperative cognitive dysfunction(POCD)in colorectal cancer patients.Meth-ods:83 patients who developed POCD after colorectal cancer surgery in our hospital from Novem-ber 2021 to September 2023 were selected as the study group,another 83 patients without POCD who underwent colorectal cancer surgery were as control group.Spearman method was applied to analyze the correlation between serum CHI3L1,CXCL16 expression levels and MMSE score;re-ceiver operating characteristic(ROC)curve was applied to analyze the predictive value of intraopera-tive rSO2 combined with serum CHI3L1 and CXCL16 for postoperative POCD in colorectal cancer patients.Results:There was statistically difference in the postoperative MMSE scores between the study group and the control group(P＜0.05);there was no statistically difference in rSO2 level between the two groups at T0 and T1 time points(P＞0.05),while there was statistically difference in rSO2 level at T2,T3,T4,and T5 time points(P＜0.05),and the change rate of rSO2 in the study group was higher than that in the control group(P＜0.05);the expression levels of serum CHI3L1 and CXCL16 in the study group were higher than those in the control group(P＜0.05);the expres-sion levels of serum CHI3L1 and CXCL16,and the intraoperative change rate of rSO2 were nega-tively correlated with MMSE score(P＜0.05);the area under the curve(AUC)of serum CHI3L1,CXCL16 levels,and rSO2 change rate alone for predicting postoperative POCD in colorectal cancer patients was 0.790,0.754,and 0.870,respectively,however,the AUC predicted by the combina-tion of the three was 0.944,which was better than their individual predictions(Zcombination-CHI3L1=4.742,Zcombination-XCL16=5.081,Zcombination-rSO2 change rate=2.986,P＜0.05).Conclusion:The combination of intraop-erative rSO2 and serum CHI3L1 and CXCL16 expression have high predictive efficacy for postop-erative POCD in colorectal cancer patients.

Aim To investigate the effect of quercetin(Que)on podocyte inflammatory injury and the under-lying mechanism.Methods MPC5 cells were divided into normal glucose group(NG),mannitol group(MA),high glucose group(HG)and high glucose+quercetin group(HG+Que).Cell proliferation and apoptosis were detected by CCK-8 and flow cytometry.The expression of SIRT1,STAT3,apoptosis-related proteins(Bax,Bcl-2,caspase-3)and pyroptosis pro-tein GSDME was detected by Western blot.The ex-pression levels of inflammatory factors(IL-6,TNF-α,IL-18,IL-1β)in cell supernatants were detected by ELISA.Then small interfering RNA technology was used to knockdown SIRT1 expression.To further eval-uate the biological significance of SIRT1 in response to high glucose and Que treatment,negative control group(HG+si-NC+Que)and SIRT1 interference group(HG+si-SIRT1+Que)were added in the presence of high glucose and Que.Results Compared with the high glucose group,40 μmol·L-1 Que could alleviate the apoptosis of MPC5 cells induced by high glucose,decrease the expression of apoptosis related protein Bax and caspase-3,as well as increase the expression of anti-apoptotic protein Bcl-2;ELISA results showed that Que could decrease the expression of TNF-α,IL-6,IL-1 β and IL-18 induced by high glucose.Mechanical-ly,Que could alleviate the inhibitory effect of high glu-cose on the expression of SIRT1,and further decrease the activation of STAT3 and N-GSDME,and inhibit pyroptosis.Compared with the si-NC group,si-SIRT1 group could reverse the protective effect of Que on the high glucose induced inflammatory damage of podo-cytes,the expression of apoptotic proteins Bax and caspase-3 increased,while the expression of anti-apop-totic protein Bcl-2 decreased.At the same time,the levels of inflammatory cytokines TNF-α,IL-6,IL-1 βand IL-18 in supernatants increased,and the expres-sion of STAT3 and N-GSDME increased.Conclusion Que could inhibit pyroptosis and relieve the inflam-matory damage of podocytes through SIRT1/STAT3/GSDME pathway.

OBJECTIVE: To compare the long-term follow-up effect and complications of ceramic on ceramic (CoC) interface and ceramic on polyethyleneon ceramic (CoP) interface in primary total hip arthroplasty, and provide clinical evidence. METHODS: Search PubMed, EMBase, the CoChrane Library databases, Web of science, Wanfang database, and CNKI from January 2000 to September 2021, screening and inclusion of randomized controlled trials (RCTs) comparing the long-term efficacy and complications of CoC interface and CoP interface in total hip arthroplasty. Literature screening, quality evaluation and data extraction were carried out according to the inclusion and exclusion criteria, using Review Manager 5.3 statistical software. The software was used to perform statistical analysis on joint function, revision, prosthesis fracture, abnormal joint noise, and prosthesis wear rate after CoC or CoP. RESULTS: Seven RCTs studies were included, including 390 cases of hips with CoC artificial joints and 384 cases of hips with CoP artificial joints. The long-term joint function improvement of CoC and CoP artificial joints was similar and there was no significant differences, with an average difference was MD=0.63, 95%CI=(-1.81, 3.07), P=0.61. About the postoperative complications, CoC artificial joints have higher incidence rate of abnormal joint noise, with odds ratio (OR)=11.05, 95%CI=(2.04, 59.84), P=0.005. CoP artificial joints wear faster, with an average MD=-87.11, 95%CI=(-114.40, -59.82), P<0.000 1. There was no significant difference between the two groups in the replacement-related complications such as joint dislocation, prosthesis loosening, osteolysis, and the rate of prosthesis revision caused by various reasons. CONCLUSION The clinical function results and complications of CoC artificial joints are comparable to those of CoP artificial joints. Although CoP artificial joint prosthesis has a faster wear rate, it does not affect joint function and increase complications, and there is no abnormal joint noise. CoC is expensive and the long-term efficacy is equivalent to CoP. Clinicians should consider cost performance when choosing CoC.
