Background and Aims:Complex choledocholithiasis often coexists with stenosis of the ampulla of Vater,which increases the difficulty and complexity of treatment.If only the stones in the bile duct are removed without addressing the ampullary stenosis,the disease is prone to recurrence.Previously,most treatments involved the use of endoscopic retrograde cholangiopancreatography(ERCP)to guide the wire for sphincterotomy and stone extraction,followed by laparoscopic cholecystectomy.However,ERCP has limitations in handling complex cases.In response,our team pioneered a new method of treating choledocholithiasis combined with stenosis of the ampulla of Vater via a transabdominal approach.This study was performed to investigate the feasibility and efficacy of this method,aiming to provide a new therapeutic option for clinical practice.Methods:A randomized controlled study was conducted with 120 patients treated at Chengdu Second People's Hospital from 2021 to 2023 for gallbladder stones and choledocholithiasis with stenosis of the ampulla of Vater.Patients were divided into an observation group and a control group,with 60 cases in each group.The observation group underwent laparoscopic cholecystectomy with choledochotomy for stone extraction,followed by retrograde guidance of duodenal papillary sphincterotomy through the opened bile duct,simultaneously treating gallbladder,bile duct stones,and stenosis of the ampulla of Vater.The control group underwent traditional ERCP approach for sphincterotomy,stone extraction,and laparoscopic cholecystectomy.Perioperative variables were collected for both groups and the surgical outcomes were compared.Results:Among the 120 patients,54 were male and 66 were female.There were no statistically significant differences between the two groups in terms of stone extraction success rate,intraoperative blood loss,postoperative 24-h total bilirubin,direct bilirubin,transaminases,white blood cell count,jaundice relief time,or incidence rates of bile leakage,retroperitoneal bleeding/infection,and severe pancreatitis(all P>0.05).The observation group had significantly shorter average operative time and postoperative hospital stay compared to the control group(98.67 min vs.110.8 min,P<0.05;3.81 d vs.5.61 d,P<0.05).Additionally,the observation group had a significantly lower incidence of postoperative hyperamylasemia and/or hyperlipasemia and mild pancreatitis(1.67%vs.25.00%,P<0.001;0 vs.10%,P=0.027).Conclusion:The novel transabdominal approach is superior to the ERCP approach in terms of reducing surgery time and hospitalization time,and it carries a lower risk of postoperative mild pancreatitis and hyperamylasemia and/or hyperlipasemia.The stone extraction success rate is comparable to that of ERCP,making it a viable alternative treatment option.

Objective:To investigate the association between serum uric acid trajectories and the risk of renal function decline and diabetic kidney disease(DKD) incidence in elderly patients with type 2 diabetes mellitus.Methods:This retrospective cohort study included 5 037 elderly patients with type 2 diabetes mellitus aged 60 years and above who underwent at least three health examinations between 2019 and 2023, with 2019 as the baseline. Latent growth mixture modeling(LGMM) was employed to identify distinct serum uric acid trajectories. Renal function changes and DKD incidence were followed from 2020 to 2023. Binary logistic regression models were used to assess the association between serum uric acid trajectories and the risks of renal function decline and DKD.Results:Two distinct serum uric acid trajectory groups were identified based on model selection criteria: A stable group( n=4 485, 89.04%) and an inverted U-shaped group( n=552, 10.96%). After adjusting for potential confounders, compared with the stable trajectory group, the inverted U-shaped group showed a significantly increased risk of estimated glomerular filtration rate(eGFR) <60 mL·min -1·(1.73 m 2) -1, ≥25% decline in eGFR, doubling of serum creatinine, and DKD events, with OR(95% CI) of 1.99(1.28-3.09), 2.27(1.65-3.13), 1.52(1.09-3.02), and 1.52(1.27-1.82), respectively(all P<0.05). In addition, multivariate analysis indicated that elevated baseline serum uric acid levels were also associated with an increased risk of adverse renal outcomes and DKD incidence; However, the magnitude of the associations was lower than that observed for serum uric acid trajectory groups. Conclusions:An inverted U-shaped serum uric acid trajectory is significantly associated with an increased risk of renal function progression and DKD in elderly patients with type 2 diabetes mellitus. These findings highlight the importance of long-term dynamic monitoring of serum uric acid levels to facilitate early identification and intervention for high-risk individuals.

Objective To compare the clinical efficacy of modified multi-side hole nasobiliary drainage(MHND)via the percuta-neous transhepatic cholangiography(PTC)route with traditional percutaneous transhepatic cholangial drainage(PTCD)for palliative treatment of patients with advanced obstructive cholangiocarcinoma.Methods A retrospective analysis was conducted on the data from 66 patients with advanced cholangiocarcinoma who underwent biliary drainage.Results Both groups normalize temperature and alleviate symptoms of acute cholangitis within 24 h post-puncture.There was no statistically significant difference in laboratory indicators such as white blood cell(WBC),total bilirubin(TBiL),alanine transaminase(ALT),aspartic transaminase(AST)at 48 h post-operation,and in the incidence of bile leakage,biliary peritonitis,and cholangitis during the postoperative hospital stay(P>0.05).However,the incidence of postoperative electrolyte disorders,gastrointestinal symptoms,and the recurrence rate of gastrointestinal symptoms during the follow-up period were significantly higher in the PTCD group compared to the MHND group,while the recur-rence rate of biliary tract infections was slightly higher in the MHND group compared to the PTCD group.The differences between the two groups were statistically significant(P<0.05).Conclusion Modified MHND shows better clinical efficacy in the treatment of patients with advanced tumor jaundice.Compared with traditional PTCD,it not only effectively reduces jaundice and relieves acute cholangitis but also significantly reduces gastrointestinal symptoms during the postoperative period,thereby improving the quality of life for patients.However,it is noteworthy that it may also increase the risk of biliary tract infections.

Cemental tear is a rare and indetectable condition unless obvious clinical signs present with the involvement of surrounding periodontal and periapical tissues. Due to its clinical manifestations similar to common dental issues, such as vertical root fracture, primary endodontic diseases, and periodontal diseases, as well as the low awareness of cemental tear for clinicians, misdiagnosis often occurs. The critical principle for cemental tear treatment is to remove torn fragments, and overlooking fragments leads to futile therapy, which could deteriorate the conditions of the affected teeth. Therefore, accurate diagnosis and subsequent appropriate interventions are vital for managing cemental tear. Novel diagnostic tools, including cone-beam computed tomography (CBCT), microscopes, and enamel matrix derivatives, have improved early detection and management, enhancing tooth retention. The implementation of standardized diagnostic criteria and treatment protocols, combined with improved clinical awareness among dental professionals, serves to mitigate risks of diagnostic errors and suboptimal therapeutic interventions. This expert consensus reviewed the epidemiology, pathogenesis, potential predisposing factors, clinical manifestations, diagnosis, differential diagnosis, treatment, and prognosis of cemental tear, aiming to provide a clinical guideline and facilitate clinicians to have a better understanding of cemental tear.

For patients with advanced non-small cell lung cancer (NSCLC) harboring sensitive epidermal growth factor receptor (EGFR) mutations, guidelines prioritize the use of third-generation EGFR-tyrosine kinase inhibitors (EGFR-TKIs), which offer higher objective response rate (ORR), longer progression-free survival (PFS), and better quality of life. However, due to the low proportion of elderly patients enrolled in clinical trials, the existing evidence is insufficient to fully guide clinical practice. This review examines the efficacy and safety differences of third-generation EGFR-TKIs as monotherapy or in combination in the elderly NSCLC by integrating subgroup analyses or pre-specified research objectives from prospective and retrospective studies. The results show that third-generation EGFR-TKIs have comparable efficacy in elderly patients to younger populations and are well-tolerated. Although combination therapies may extend survival time, the associated increased toxicity necessitates careful risk-benefit assessment.

Objective:To compare the consistency of microarray chemiluminescent protein chip and immunoblotting in the autoantibody spectrum of patients and the diagnostic efficacy of systemic lupus erythematosus(SLE), and to explore the correlation between the detection results of protein microarray and clinical indicators and lymphocyte subsets.Methods:Serum autoantibodies in 649 samples collected between December 2023 and December 2024 in Nanjing Drum Tower Hospital were analyzed using the microarray chemiluminescent protein chip method, with 401 samples simultaneously tested by immunoblotting. Kappa coefficient assessed inter-method consistency. Diagnostic performance was compared via ROC curves. Spearman correlation analysis evaluated relationships between autoantibody levels and SLEDAI-2000 scores, clinical parameters, and lymphocyte subsets.Results:The two methods demonstrated good consistency across 14 antinuclear antibodies, with optimal agreement for anti-SSA/Ro ( Kappa=0.845, P<0.001), anti-SSB ( Kappa=0.825, P<0.001), and anti-CENP B ( Kappa=0.851, P<0.001). The protein chip method significantly improved SLE diagnostic efficacy, particularly for anti-dsDNA (AUC difference=0.291, P<0.001) and anti-Sm antibodies (AUC difference=0.295, P<0.001). Combined detection of anti-SSA/Ro and anti-nRNP/Sm antibodies achieved superior diagnostic performance (AUC=0.927). Anti-dsDNA, anti-histone, and anti-nucleosome antibodies positively correlated with SLEDAI-2000 ( r=0.408, 0410, 0.384, all P<0.001), complement ( P<0.001), and 24-hour urinary protein ( r=0.374, 0.387, 0.301, all P<0.001). Immunological analysis showed that the proportion of NK cells was generally negatively correlated with antinuclear antibodies such as anti-dsDNA ( r=-0.352, P<0.001) and anti-Sm ( r=-0.328, P<0.001) antibodies. Meanwhile, the proportion of CD8 + T cells was positively correlated with anti-nRNP/Sm ( r=0.229, P=0.002) and anti-Sm antibodies ( r=0.211, P=0.005). The proportion of CD4 + T cells was negatively correlated with anti-SSA/Ro ( r=-0.239, P<0.001), while the proportion of B cells was positively correlated with anti-dSDNA antibody ( r=0.300, P<0.001). Conclusion:The protein chip method showed strong consistency with immunoblotting for detecting 14 autoantibodies but demonstrated superior SLE diagnostic efficacy. The combined use of multiple detection methods can enhance the reliability of clinical diagnosis.
