Objective To explore the potential causal links between micronutrient levels and the risk of immune-mediated inflammatory skin disease(IMID).Methods Leveraging publicly accessible genome-wide association study(GWAS)datasets,fifteen specific micronutrients were identified as exposure variables,while four prevalent IMID:Psoriasis,atopic dermatitis,urticaria,and alopecia areata were designated as study outcomes.Robust instrumental variables were meticulously selected to facilitate the Mendelian randomization analysis.The main assessment used the inverse-variance weighting(IVW)method,complemented by an assortment of Mendelian randomization methodologies,inclusive of MR-Egger,weighted median estimate(WME)and weighted mode(WM).Rigorous sensitivity analyses were conducted to bolster the robustness of the findings.Results Vitamin D exhibited a significant inverse association with the risk of psoriasis(OR=0.996,P=0.001,95％CI:0.994-0.998),corroborated by consistent trends across WME,MR-Egger,and WM methods.Phosphorus demonstrated a positive correlation with urticaria risk(OR=5.634,95％CI:1.792-17.711,P=0.003),with findings in alignment with WME and WM methods.Copper was found to be positively associated with atopic dermatitis risk(ORIVW=1.234,P=0.0007,95％CI:1.092-1.394),and vitamin E levels were significantly related to the risk of urticaria(OR=26.643,P=0.013,95％CI:1.981-358.333).Sensitivity analysis did not show heterogeneity and pleiotropy(P＞0.05).Conclusion The study establishes a causal relationship between vitamin D levels and the risk of psoriasis,suggesting that augmenting vitamin D intake could be a viable dietary intervention for psoriasis prevention.These findings offer novel insights into the preventative and therapeutic strategies for IMID.

Objective:To evaluate the short-term efficacy of endoscopic-laparoscopic regional gastric resection combined with sentinel lymph node basin dissection in patients with early-stage gastric cancer.Methods:This is a retrospective case series study. Data of 17 consecutive early gastric cancer patients from a prospective cohort at Beijing Friendship Hospital,Capital Medical University were analyzed between August 2023 and August 2024. Sixteen cases were from the department of general surgery and 1 from the department of gastroenterology. The cohort included 9 males and 8 females,with a mean age of 61.4 years (range: 46 to 79 years). Clinical data,including demographics,pathological features,surgical procedures,and follow-up outcomes,were collected through medical records and databases. All patients were followed for over 3 months,with follow-up ending on December 5,2024.Results:A total of 17 patients were involved. Among them, 5 patients underwent endoscopic submucosal dissection (ESD) combined with laparoscopic sentinel lymph node dissection (LSBD),and another 3 patients who underwent complete ESD resection received LSBD due to pathological stage meeting the expanded indications. 6 patients who underwent non-curative ESD resection received laparoscopic gastric regional resection (LRG) combined with LSBD,and another 3 patients directly received LRG combined with LSBD. The average number of sentinel lymph nodes dissected before surgery ( M(IQR)) was 8.9 (4.5) (range: 4 to 21),and the detection rate and accuracy rate were both 100%. Postoperative pathology confirmed that there was no metastasis in the sentinel lymph nodes of 5 patients who underwent ESD combined with LSBD and 3 patients who underwent LSBD after complete ESD resection. The vertical and horizontal margins of ESD were all negative. One patient was an absolute indication for ESD. For the 6 patients who underwent non-curative ESD resection combined with LRG and LSBD,the horizontal margins were all negative. Two patients showed 1 metastasis in each of the 21 and 9 sentinel lymph nodes during the operation,and additional distal gastrectomy was performed during the operation. Postoperatively,73 and 39 lymph nodes were retrieved respectively. The former had 1 additional metastasis,while the latter had no metastasis. Among the 3 patients who underwent direct LRG combined with LSBD,the horizontal margins were negative. One patient was confirmed as an absolute indication for ESD by postoperative pathology,and one patient had 1 metastasis in 8 sentinel lymph nodes during the operation,and additional distal gastrectomy was performed. Postoperatively,there was no metastasis in 54 lymph nodes. All patients had no complications such as infection,bleeding,perforation,or death after surgery. Among the 14 patients who did not receive additional radical surgery,they were able to pass gas and defecate within 3 days after surgery,with an average hospital stay of 6 days. The nutritional indicators and gastric radionuclide emptying imaging half-emptying time were similar to those before surgery at 3 months after surgery. Conclusions:Laparoscopic and endoscopic cooperative regional gastrectomy with sentinel lymph node basin dissection has the advantages of minimal invasiveness,preservation of gastric function,and precise treatment. It maybe suitable for patients with early-stage gastric cancer at high risk of lymph node metastasis and has good short-term efficacy.

Objective To investigate the predictive value of PCSK9 gene rs562556 polymorphism for major adverse cardiovascular events(MACE)after percutaneous coronary intervention(PCI)in patients with type 2 diabetes mellitus(T2DM)complicated by acute myocardial infarction(AMI).Methods A total of 97 patients were involved in this study with T2DM complicated by AMI,who underwent PCI at The Third Affiliated Hospital of Qiqihar Medical University between January 2019 and December 2021.Based on MACE occurrence during a 2-year follow-up period,patients were divided into non-MACE group and MACE group(n=57 and 40,respectively).Clinical biochemical parameters,including blood glucose and lipid levels,were recorded.Plasma PCSK9 levels were assessed using enzyme-linked immunosorbent assay.Plasma PCSK9 gene rs562556 polymorphism was detected through sequencing.Kaplan-Meier curve analysis was performed to assess how rs562556 polymorphism impacts MACE incidence post-PCI.Multivariate logistic regression was applied to identify independent MACE-associated risk factors.ROC curve analysis was performed to evaluate the predictive value of rs562556 poly-morphism and key clinical variables for MACE occurrence post-PCI.Results Compared to the non-MACE group,patients in the MACE group exhibited significantly higher age,heart rate,creatinine,NT-proBNP,LDL-C,and plasma PCSK9 levels,along with higher hyper-tension and coronary atherosclerotic heart disease prevalence,and lower diastolic blood pressure(all P＜0.05).In patients with T2DM and AMI,the rs562556 genotype AA of the PCSK9 gene positively correlated with plasma PSCK9 levels(r=0.61,P＜0.000 1).The frequen-cies of the rs562556 genotype AA and allele A were significantly higher in the MACE compared to the non-MACE group(P＜0.05).The AA genotype of the PCSK9 gene rs562556 was associated with an increased risk of MACE during follow-up in patients with T2DM and AMI(P＜0.05).After adjusting for other confounding variables,advanced age,increased NT-proBNP and PCSK9 levels,and the rs562556 AA genotype were identified as independent risk factors for MACE post-PCI in this patient population.Combined analysis of these factors demonstrated superior predictive value for MACE occurrence compared to individual markers.Conclusion The PCSK9 gene rs562556 genotype AA is associated with a significantly increased risk of MACE within two years post-PCI in patients with T2DM and AMI,sug-gesting that it could serve as a promising predictive biomarker for post-PCI MACE in the given population.

Objective:To translate the Birth Satisfaction Scale-Revised (BSS-R) into Chinese and assesses the psychometric properties of this tool.Methods:Following the Beaton cross-cultural adaptation guidelines, the Chinese version of BSS-R was formed through forward translation, back translation, expert consultation, and pre-testing. The present study was conducted in a sample of 347 women took part between 6-8 weeks postpartum, from the postpartum clinics of two tertiary hospitals in Sichuan province.Results:Totally 340 questionnaires were effectively collected with a majority of respondents aged 30-39 accounting for 64.7% of the total. The Chinese version of BSS-R comprises 10 items, which were classified into three domains as stress experienced during labour, women′s personal attributes, and quality of care provision. The Cronbach α coefficient was 0.745 for the total scale and ranged from 0.523 to 0.738 for sub-scales. The split-half reliability was 0.746 for the total scale, and ranged from 0.523 to 0.733 for sub-scales. Exploratory factor analysis revealed the presence of three components with eigen values greater than 1, explaining a total variance of 58.868%. The fit indices showed that the original correlated three factor model of Chinese version of BSS-R was adequate.Conclusions:The Chinese version of BSS-R can be considered a clear, easily understandable and convenient tool for assessing the women′s birth satisfaction in Chinese cultural context.

Objective:To analyze the clinicopathological features of de novo early colorectal cancer and to evaluate the efficacy of endoscopic treatment.Methods:Patients with de novo early colorectal cancer who underwent endoscopic resection in Beijing Friendship Hospital, Capital Medical University from June 2020 to May 2022 were enrolled. The baseline data, endoscopic manifestations, treatment methods, postoperative pathological results and prognosis of the patients were collected retrospectively.Results:A total of 33 patients with de novo early colorectal cancer were enrolled with the age of 62.67 ± 8.62 years, and the male to female ratio was 7.25∶1. The long diameter of lesions was 0.96 ± 0.36 cm. The lesion morphology was mainly superficial phenotype (type 0-Ⅱ), accounting for 72.7% (24/33). Endoscopic submucosal dissection (ESD) was performed in 29 cases and endoscopic mucosal resection (EMR) was performed in 4 cases. Postoperative pathology showed that 11 cases (33.3%) were well differentiated tubular adenocarcinoma, of which the superficial submucosal layer was invaded in 2 cases. Twenty cases (60.6%) were moderately differentiated tubular adenocarcinoma, of which the superficial submucosa layer was invaded in 5 cases and the deep submucosa layer in 15 cases. Two cases (6.1%) were moderately-poorly differentiated tubular adenocarcinoma, where the deep submucosa layer was invaded in both. There was significant correlation between the depth of invasion and the degree of differentiation ( P<0.001), and moderately and moderately-poorly differentiated lesions were more likely to invade the deep submucosa layer. The en bloc resection rate was 100.0% (33/33), the complete resection rate was 97.0% (32/33), and the curative resection rate was 42.4% (14/33). Among the 19 patients who did not achieve curative resection, 13 patients received supplementary surgical treatment. No tumor residue or lymph node metastasis was found in the postoperative pathology. All patients were followed up for 3-25 months, and no signs of local recurrence or metastasis were found. Conclusion:Most de novo early colorectal cancers are superficial phenotype under endoscopy. The pathology is mainly moderately differentiated tubular adenocarcinoma. Endoscopic resection of de novo early colorectal cancer shows encouraging short-term efficacy.

Objective: To explore the associations of aggressive behavior with self-esteem with suicide risk in college students. Methods: A total of 4 154 college students in Suzhou, Hefei and Ma’anshan were enrolled in our study by multistage cluster sampling method during October to December 2017. Demographic characteristics, suicide risk, aggression and self-esteem of participants were evaluated by Suicidal Behaviors Questionnaire-Revised (SBQ-R), Buss & Perry Aggression Questionnaire-Chinese Version (AQ-CV) and Rosenberg Self-esteem Questionnaire separately. Aggression and self-esteem were divided into three levels, high (> P 75 ), medium ( P 25 - P 75 ) and low (< P 25 ) level, according to the percentile of the questionnaire score. Multivariate logistic regression model was used to examine the associations of aggression and self-esteem with suicide risk, and to explore gender difference. Results: The gender differences were found in suicide risk, aggressive behavior and self-esteem( χ 2=80.21, 26.47, 26.51 , P <0.01). More girls reported suicide ideation, suicide plan and suicide attempt compared to girls( χ 2=33.03, 25.11, 15.71 , P <0.01). Compared with boys, the detection rate of suicide ideation, suicide plan and suicide attempt of girls were higher( P <0.01). The high aggressive behavior and low self-esteem was correlated with increased risk of suicide, and the interaction effects of aggressive behavior and self-esteem on suicide risk was found. The students with high aggressive behavior and low self-esteem had a higher suicide risk, the multiple adjusted odds ratio was 19.39 (95% CI =11.10-33.87). Gender difference was not found in the associations of aggressive behavior and self-esteem with suicide risk ( P >0.05). Conclusion Aggressive behavior and self-esteem are correlated with suicide risk in college students.
