Objective To investigate the prognostic value of remnant lipoprotein cholesterol(RLP-C)and platelet-lymphocyte ratio(PLR)for elderly patients with acute myocardial infarction(AMI)stratified by body mass index(BMI).Methods A total of 130 elderly AMI patients admitted to our hospital from January 2022 to January 2024 were recruited,and then based on their BMI,they were categorized into low(n=18),normal(n=60),and high BMI groups(n=52).Multivariate logistic regression analysis was used to identify the risk factors for poor prognosis in elderly AMI patients.Spearman correlation analysis was conducted to examine the relationship of RLP-C and PLR with prognostic outcomes.ROC curve analysis was performed to evaluate the predictive per-formance of the two indicators for prognosis in elderly AMI patients of different BMI.Results Significant differences in RLP-C and PLR levels were observed among the above three groups(P＜0.05,P＜0.01).In the overall population,as well as in the low,normal and high BMI groups,both RLP-C and PLR were positively correlated with adverse outcomes in elderly AMI patients(P＜0.01).PLR and RLP-C were independent risk factors for poor prognosis in elderly AMI pa-tients(P＜0.01),and they were independently associated with prognosis in each BMI group(P＜0.01).The combined the three indicators together significantly improved the sensitivity and speci-ficity in predicting adverse outcomes in elderly AMI patients when compared to single indicator alone(sensitivity:54.29％,75.94％,64.18％vs 82.61％;specificity:68.83％,70.22％,72.15％vs 80.49％;P＜0.01).Conclusion RLP-C and PLR are influencing factors for poor prognosis in eld-erly AMI patients,and can serve as predictive factors for prognosis,which are helpful for provi-ding valuable guidance for early treatment and prevention of adverse outcomes.

Objective To analyze the latent classes of social alienation in colorectal cancer patients and further explore the influencing factors and cumulative effects of risk factors across different classes,thereby providing a reference for individualized interventions.Methods Convenience sampling was used to select colorectal cancer patients hospitalized in the gastrointestinal surgery and oncology departments of 3 tertiary-level hospitals in Shandong Province from January to June 2023 as the study subjects.A questionnaire survey was conducted using the General Information Questionnaire,Social Avoidance Scale,Social Anxiety Scale,UCLA Loneliness Scale,Sense of Coherence Scale,Family Cohesion Scale,and Social Support Rating Scale.Data analysis was performed using latent profile analysis and multivariate logistic regression analysis.Results A total of 292 questionnaires were distributed,with 270 valid responses collected,yielding a response rate of 92.47％.The results of the latent profile analysis indicated that social alienation among colorectal cancer patients could be categorized into 3 latent groups:the"low alienation group"(42.59％),the"high alienation-high social avoidance group"(14.08％),and the"moderate alienation-high social anxiety group"(43.33％).Results of logistic regression analysis revealed that employment status,stoma status,metastasis,sense of coherence,family cohesion,and social support were influencing factors across different categories.Moreover,a cumulative effect of sense of coherence,family cohesion,and social support on distinct categories was observed(P＜0.05).Conclusion Social alienation among colorectal cancer patients exhibits group heterogeneity.Healthcare professionals should identify the characteristic differences among patients,prioritise those with multiple risk factors,and develop targeted intervention measures to help them better integrate into society.

Objective:To investigate the serum level of hydrogen sulfide (H2 S ) and its influential factors in patients undergoing maintenance hemodialysis (M HD ) .Methods :Based on screening and exclusion criteria ,150 patients undergoing M HD were enrolled .Meanwhile ,17 healthy volunteers were collected as healthy controls .Venous blood samples of M HD patients were obtained before and after dialysis ,and fasting blood samples were collected from healthy controls .The levels including serum H2 S ,nitric oxide (NO) ,endothelin‐1 (ET‐1) ,and sulfhemoglobin were detected and the correlations among them were analyzed .Results:The levels of serum H2 S ,NO ,NO/ET‐1 and sulfhemoglobin in patients undergoing M HD were significantly lower than those in healthy control group before dialysis (P<0 .01) ,while ,there was no significant difference regarding ET‐1 and Vitamin B6 levels between these two groups (P>0 .05) .Before dialysis ,serum H2 S level was positively correlated with NO ,NO/ET‐1 ,sulfhemoglobin and eGFR (P<0 .01) ,while negatively correlated to serum creatinine .After dialysis ,serum H2 S level increased significantly ,while NO ,NO/ET‐1 decreased significantly .However ,the levels of ET‐1 , sulfhemoglobin and Vitamin B6 ,compared with those before dialysis ,did not change significantly after dialysis .Conclusions :Serum H2 S level in patients undergoing M HD decreases significantly and it is significantly correlated with NO ,sulfhemoglobin and renal function .Compared with that before hemodialysis ,the serum H2 S level increased significantly after hemodialysis .

ObjectiveTo evaluate the one-year follow-up of the therapeutic efficacy of human umbilical cord derived-mesenchymal stem cell (UC-MSC) transplantations in decompensated liver cirrhosis patients with ascites.MethodsFifty-four liver cirrhosis patients with ascites in Research Center for Biological Therapy in 302 Military Hospital were divided into treatment group (n=38) and control group (n=16) in a prospective controlled single-blinded trial.UC-MSC (0.5-1.0) × 106/kg and saline were intravenously transplanted into patients monthly for 3 times in treatment group and control group,respectively.The liver function,hepatitis B virus (HBV) DNA level,ascites and the model for end-stage liver disease(MELD)scores at different time points were compared between two groups.The comparison between groups was done by Mann-Whitney U test,and the data before and after transplantations were compared by Wilcoxon signed rank sum test.ResultsThere were no significant differences of alanine transaminase (ALT),total bilirubin (TBil),cholinesterase (CHE),HBV DNA positive rate and MELD scores at different time points between two groups (P＞0.05).However, the albumin ( A1b)level was significantly increased after 36 weeks of UC-MSC transplantation in treatment group, which were (28.47±4.45)g/L at week 0 and ( 34.82±4.50)g/L at week 48 (P=0.046). Meanwhile, the ascites reduced markedly in treatment group with (46.6 ±30.6) mm at week 0 and (6.6±13.6) mm at week 48,which were significantly different from control group at the end of follow-up (P =0.037). Conclusion UC-MSC transplantations may help to increase A1b level and reduce ascites in patients with decompensated liver cirrhosis.

Objective To analyze the efficacy and safety of glimepiride treatment as initial monotherapy in newly diagnosed patients with type 2 diabetes mellitus (T2DM).Methods This was a subgroup analysis of the GREAT study,which investigated the efficacy and safety of glimepiride as initial monotherapy in Chinese patients with T2DM.This analysis was performed in 209 patients with disease duration less than 6 months and never received any anti-diabetic drugs.The change of HbA1C,fasting plasm glucose (FPG),2 h postprandial blood glucose (2hPPG),homeostasis model assessment for β-cell function index (HOMA-β),homeostasis model assessment for insulin-resistance index(HOMA-IR),the percentage of patients with HbA1C ＜ 7.0％ at endpoint and the incidence of hypoglycemia were evaluated after 16-weeks treatment.Results After 16-weeks glimepiride treatment,HbA1C value reduced significantly from baseline to endpoint,the reduction was statistically significant (9.21％ ± 1.65％ to 6.69％±0.83％,P＜0.001),69.7％ of the patients achieved HbA1C ＜7.0％ at study endpoint.Glimepiride-treated patients also achieved a significant improvement in FPG [from (10.15 ± 2.13) mmol/L to (7.23 ± 1.50) mmol/L,P＜0.001] and 2hPPG [from (17.21 ±4.14) mmol/L to (11.62 ± 3.34) mmol/L].HOMA-β was improved from 17.21± 15.19 [11.62 (2.90,115.8)] to 41.13 ± 44.12 [28.00 (5.1,360.00)],and HOMA-IR was reduced from 2.32± 1.90 [1.76 (0.60,12.80)] to 2.07 ± 1.74 [1.63 (0.4,12.3)].The incidence of all reported symptomatic hypoglycemia was 18.2％,and the incidence of confirmed hypoglycemia was 3.8％.Conclusion This analysis showed that glimepiride treatment as an initial mono-therapy could effectively improve blood glucose control in newly diagnosed patients with T2DM,and the treatment may improve islet β cell function,and the safety profile is reasonably good.
