Objective To characterize the clinical features of the group of gout patients to facilitate earlier identifi-cation,and optimize the diagnosis and treatment of the condition.Methods The retrospective study analyzed 24 gout patients with shoulder joint(s)involved and consulted by physicians of Peking Union Medical College Hospital from March 2021 to April 2025,while 70 outpatient gout patients matched by clinical course duration and sex were enrolled as control group.Clinical data including medical history,laboratory tests,therapeutic interventions.Prog-nosis was systematically collected to delineate the distinctive clinical manifestations of the patients.Results All 24 gout patients with shoulder joints involved were male,aged(43.16±13.13)years and had an average BMI of 27.70±4.63.The duration of gout was 8(5,12)years while of those patients had an early onset before 30 years old.The maximal serum uric acid concentration was(754.15±175.79)μmol/L.It was shown by case review that 16.67％of the patients were asymptomatic,and 79.17％suffered from shoulder pain.A quarter of the patients developed subcutaneous tophi.All the patients affected(P＜0.05).The affected joints ascended from lower extremities to the upper averagely took 4.72±2.80 years and had heavier burden of hyperuricemia(P＜0.05),while no significant difference was found in renal function and inflammation level.Conclusions Gout patients with shoulder joints involvement are older and have atypical manifestation.The diagnosis needs support of imaging or ar-throcentesis.

Objective:To evaluate the role of stimulator of interferon genes (STING) in postoperative cognitive dysfunction (POCD) and the relationship with pyroptosis in hippocampal cells in aged mice.Methods:Forty-eight SPF healthy male C57BL/6 mice, aged 18 months, weighing 23-28 g, were assigned to 4 groups ( n=12 each) using a random number table method: control group (C group), POCD group (P group), STING inhibitor C-176 group (PC group), and C-176 solvent group (PV group). The mice underwent Morris water maze training for 4 days prior to model establishment. Mice in P, PC and PV groups underwent tibial fracture and intramedullary pin fixation under sevoflurane anesthesia to establish the POCD model, while mice in C group received no treatment. The STING inhibitor C-176 (750 nmol/200 μl) and an equal volume of C-176 solvent were intraperitoneally injected at 30 min before establishment of the model in PC and PV groups, respectively. The open field test was performed on the 5th day after model preparation, the novel object recognition test was conducted on the 6th day, and the Morris water maze test was performed on the 7th day. Mice were sacrificed under anesthesia to collect the hippocampus for determination of the expression of STING, phosphorylated STING (p-STING), nucleotide-binding oligomerization domain-like receptor protein 3 (NLRP3), cleaved caspase-1, and gasdermin-D (GSDMD)-NT by Western blot. Results:There were no statistically significant differences in the parameters of the training phase of the Morris water maze test and the open field test among the four groups ( P>0.05). Compared with C group, the recognition index in the novel object recognition test was significantly decreased, the number of crossing the original platform was reduced and the duration spent in the target quadrant was shortened in the Morris water maze test, and the expression of STING, NLRP3, cleaved caspase-1, and GSDMD-NT in hippocampal neurons was up-regulated in P, PC and PV groups, and the expression of p-STING was significantly up-regulated in P and PV groups ( P<0.05). Compared with P group, the recognition index in the novel object recognition test was significantly increased, the number of crossing the original platform was reduced and the duration spent in the target quadrant was prolonged in the Morris water maze test, and the expression of p-STING, NLRP3, cleaved caspase-1, and GSDMD-NT in hippocampal neurons was down-regulated in PC group ( P<0.05). Compared with PC group, the recognition index in the novel object recognition test was significantly decreased, the number of crossing the original platform was reduced and the duration spent in the target quadrant was shortened in the Morris water maze test, and the expression of p-STING, NLRP3, cleaved caspase-1 and GSDMD-NT was up-regulated in PV group ( P<0.05). Conclusions:STING is involved in the development of POCD in aged mice, and the mechanism may be related to promotion of pyroptosis in hippocampal cells.

Objective:To evaluate the alveolar ridge preservation effect of immediate implantation at extraction site with the im-proved CBCT measuring method.Methods:Eighty patients with extraction site were divided into test group A,B,C and control group.The patients were treated by means of immediate implant placement combined with large flap surgery,guided bone regener-ation(GBR)using mass Bio-Oss bone particles in the group A(the thickness of facial bone wall＜1 mm);The patients were trea-ted by means of immediate implant placement combined without flap surgery and bone graft in the group B(the thickness of facial bone wall ≥1 mm and＜2 mm)and C(the thickness of facial bone wall ≥2 mm),the CGF was implanted in the jumping space only when the thickness of jumping space was＞2 mm.In the control group,the alveolar sockets healed naturally without any in-tervention or treatment.CBCT was taken before surgery,immediately after surgery,and 6 months after surgery to evaluate the height and width of alveolar bone,the thickness of facial bone wall and jumping space.Results:The reduction of alveolar ridge height in group A,B,C and control group was(0.41±0.13,0.94±0.18,0.59±0.12,1.31±0.19)mm,The reduction of alveolar ridge width in group A,B,C and control group was(0.93±0.10,1.48±0.21,1.12±0.17,1.66±0.16)mum.The re-sults of four groups were statistically different(F=177.0,P＜0.001;F=125.3,P＜0.001).The alveolar ridge thickness of facial bone wall in group A,B,C and con-trol group was(0.98±0.25,2.39±0.28)mm,(1.43±0.52,2.10±0.33)mm,(2.17±0.41,2.79±0.27)mm before surgery and six months after immediate implantation.The results of each group were statistically different between before surgery and six months after immediate implantation(t=16.45,P＜0.001;t=7.357,P＜0.001;t=5.488,P＜0.001).Patients in three test groups had the thickness of jumping space＞2 mm and ≤2 mm,and the reduction of alveolar ridge width was(0.78±0.18,0.88±0.17)mm.The results were statistically different(t=17.18,P=0.018).Conclusion:The alveolar ridge preservation was obtained by means of immediate implant placement combined with large flap surgery,guided bone regeneration(GBR)using mass Bio-Oss bone particles at extraction site with the thickness of facial bone wall＜1 mm;The alveolar ridge preservation was obtained without flap surgery and GBR at extraction site with the thickness of facial bone wall≥1 mm.The preservation of soft and hard tissue was better in the axial palatal side of immediate implantation with the thickness of jumping space＞2 mm than that with the thickness of jumping space≤2 mm.

This study aimed to comprehensively examine the association of gallstones, cholecystectomy, and cancer risk. Multivariable logistic regressions were performed to estimate the observational associations of gallstones and cholecystectomy with cancer risk, using data from a nationwide cohort involving 239 799 participants. General and gender-specific two-sample Mendelian randomization (MR) analysis was further conducted to assess the causalities of the observed associations. Observationally, a history of gallstones without cholecystectomy was associated with a high risk of stomach cancer (adjusted odds ratio (aOR)=2.54, 95% confidence interval (CI) 1.50-4.28), liver and bile duct cancer (aOR=2.46, 95% CI 1.17-5.16), kidney cancer (aOR=2.04, 95% CI 1.05-3.94), and bladder cancer (aOR=2.23, 95% CI 1.01-5.13) in the general population, as well as cervical cancer (aOR=1.69, 95% CI 1.12-2.56) in women. Moreover, cholecystectomy was associated with high odds of stomach cancer (aOR=2.41, 95% CI 1.29-4.49), colorectal cancer (aOR=1.83, 95% CI 1.18-2.85), and cancer of liver and bile duct (aOR=2.58, 95% CI 1.11-6.02). MR analysis only supported the causal effect of gallstones on stomach, liver and bile duct, kidney, and bladder cancer. This study added evidence to the causal effect of gallstones on stomach, liver and bile duct, kidney, and bladder cancer, highlighting the importance of cancer screening in individuals with gallstones.

Background/Aims: Low educational attainment is a well-established risk factor for nonalcoholic fatty liver disease (NAFLD) in developed areas. However, the association between educational attainment and the risk of NAFLD is less clear in China. Methods: A cross-sectional study including over 200,000 Chinese adults across mainland China was conducted. Information on education level and lifestyle factors were obtained through standard questionnaires, while NAFLD and advanced fibrosis were diagnosed using validated formulas. Outcomes included the risk of NAFLD in the general population and high probability of fibrosis among patients with NAFLD. Logistic regression analysis was employed to estimate the risk of NAFLD and fibrosis across education levels. A causal mediation model was used to explore the potential mediators. Results: Comparing with those receiving primary school education, the multi-adjusted odds ratios (95% confidence intervals) for NAFLD were 1.28 (1.16 to 1.41) for men and 0.94 (0.89 to 0.99) for women with college education after accounting for body mass index. When considering waist circumference, the odds ratios (95% CIs) were 0.94 (0.86 to 1.04) for men and 0.88 (0.80 to 0.97) for women, respectively. The proportions mediated by general and central obesity were 51.00% and 68.04% for men, while for women the proportions were 48.58% and 32.58%, respectively. Furthermore, NAFLD patients with lower educational attainment showed an incremental increased risk of advanced fibrosis in both genders. Conclusions In China, a low education level was associated with a higher risk of prevalent NAFLD in women, as well as high probability of fibrosis in both genders.
