Objective: To explore the influencing factors for implementation of weight management services in primary medical and healthcare institutions, so as to provide references for implementing sustainable services of weight management. Methods: From May to June 2025, Pinghu City, Zhejiang Province was selected as the survey site. Personnel responsible for weight management in primary medical and healthcare institutions were selected as the survey subjects using a combined method of purposive sampling and snowball sampling. Based on the five core domains of the consolidated framework for implementation research (CFIR), a semi-structured interview outline for weight management services in primary medical and healthcare institutions was designed. Original data was collected through face-to-face semi-structured interviews. Interview data was organized and analyzed using framework analysis. Factors affecting weight management services were quantitatively analyzed by referencing CFIR's structural rating criteria. Results: A total of 21 participants completed interviews, covering positions in nutrition, endocrinology, traditional Chinese medicine, general practice, maternal health, and public health. There were 9 males and 12 females. Fifteen participants (71.43%) were aged 35 years and above, 18 (85.71%) held a bachelor's degree or higher, and 15 (71.43%) were frontline medical staff. Fifteen factors affecting weight management services were identified across five domains: innovation, outer setting, inner setting, individuals, and implementation process. Six barrier factors were identified: difficulties in policy implementation, time-consuming interventions, limited incentive measures, lack of professional skills, unclear weight-loss plans and goal setting, and imperfect follow-up and evaluation mechanisms. Three neutral factors were identified: the development and refinement of policies and regulations, the implementation of weight management training, and the optimization of the referral process within integrated healthcare systems (medical alliances / communities). Six facilitating factors were identified: the relatively significant advantages of lifestyle interventions, collaboration and coordination across multiple departments, cooperative communication among different units within the institution, the inherent convenience of primary care settings, a strong sense of professional responsibility, and the establishment of multidisciplinary teams. Conclusions The delivery of weight management services in primary medical and healthcare institutions is influenced by a wide array of factors across multiple domains. It requires policy support, multi-department coordination, a practice-oriented training system, optimized team resource allocation, incentives, and improved professional skills of medical staff to jointly promote long-term implementation.

Objective To analyze the epidemiological characteristics and immunization history of pertussis cases in Yichang City, Hubei Province from 2018 to 2023. Methods Data on the incidence and immunization history of pertussis cases were collected in Yichang City from 2018 to 2023, and the epidemiological characteristics was analyzed and described. Results A total of 109 cases of pertussis were reported in Yichang from 2018 to 2023, and the annual average reported incidence rate was 0.45/100,000. The incidence rate reported in each year was between 0～1.58/100,000. The area with the highest annual reported incidence rate was Xiling District (1.19/100,000). There was a statistically significant difference in the incidence rate between different years (χ²=208.26, P < 0.001). The annual reported incidence rate showed a significant increasing trend (χ² trend =125.71, P < 0.001). The ratio of male to female cases was 1.22. There was no significant difference in the annual reported incidence rates between males and females (χ²=0.85, P=0.36). Children aged 3-9 years accounted for 60.55%. Students and scattered children accounted for 45.87% and 36.70%, respectively. Before the onset of the disease, 72.48% had a history of immunization with pertussis-containing vaccine, and 27.52% had no history of immunization. The shortest interval between the last dose of pertussis-containing vaccine and the onset of the disease was 8 days, the longest was 4057 days, and the median was 1882 days. Conclusion From 2018 to 2023, the reported incidence of pertussis in Yichang City has been on the rise, with the majority of cases occurring in children and students under the age of 9. It is recommended to strengthen pertussis disease monitoring.

Objective To explore the influencing factors of hypothermia after extraperitoneal laparoscopic radical prostatectomy in prostate cancer patients over 80 years old,so as to improve the effectiveness of treatment.Methods The clinical data of 26 cases of prostate cancer patients over 80 years old who underwent extraperitoneal laparoscopic radical prostatectomy in Shanghai 411 hospital from January 2021 to December 2023 were analyzed retrospectively.The incidence of postoperative hypothermia was investigated.Univariate and multivariate Logistic regression analyses were used to analyze the related factors of postoperative hypothermia in elderly patients.Results The incidence of hypothermia was 61.54%(16/26).Univariate analysis indicated that body mass index(BMI),intraoperative thermal insulation,intraoperative infusion volume,operation time,and anesthesia time were related to the occurrence of postoperative hypothermia in elderly patients(all P<0.05).Multivariate Logistic regression analysis indicated that BMI≤24,intraoperative infusion volume>2 000 ml,anesthesia time>3 h and operation time>2.5 h were high risk factors for postoperative hypothermia in patients over 80 years old.Conclusion The independent influencing factors of hypothermia after extraperitoneal laparoscopic prostatectomy for selected prostate cancer patients over 80 years old are BMI,intraoperative infusion volume,duration of anesthesia,and operation time.These factors should be paid more attention during perioperative period in order to improve clinical safety.

Nuclear polyadenosine-binding protein 1(PABPN1)is the only known polyadenosine-binding protein in the cell nucleus of mammals.The first attention was resulted from relevant research on oculopharyngeal muscular dystrophy(OPMD),where mutations and aggregation of PABPN1 were found to be the main pathogenesis of the disease.Recently,PABPN1 is found to be abnormally expressed in some tumor tissues,and confirmed to be in-volved in regulating selective polyadenylation,which leads to the occurrence and development of various human tumors.This article briefly introduces the structure and function of PABPN1,reviews progress of research related to PABPN1 and tumors in recent years,and provide our thought for exploring point potential pathways for future re-search on the role and mechanism of PABPN1 in the occurrence and development of tumors.

Objective To investigate the effects of circular RNA APLP2(circAPLP2)on the proliferation,migra-tion,and invasion of human colorectal cancer(CRC)cell lines by regulating microRNA-455-3p(miR-455-3p)/Stathmin1(STMN1)axis.Methods RT-qPCR was used to detect the expression of circAPLP2,miR-455-3p and STMN1 in CRC and normal colorectal cell lines and the optimal cell line was screened.Proliferation,migra-tion and invasion were detected by MTT assay,scratch assay and Transwell assay,respectively.The relationship between circAPLP2 and miR-455-3p,between miR-455-3p and STMN1 was confirmed by dual Lucifer's reporter gene assay.Results CircAPLP2 and STMN1 were highly expressed in CRC cells,miR-455-3p showed a low ex-pression.Knocking down circAPLP2 resulted in a decrease in rate of survival and of scratch healing rate and in-vasion of SW620 cells,An up regulation of miR-455-3p expression,a down regulation of STMN1,cyclin D1,N-cadherin protein expression and an up regulation of E-cadherin protein expression were also found(P<0.05).Inhibition of miR-455-3p expression reversed inhibitory effect of knocking down circAPLP2 on SW620 cell prolif-eration,migration,and invasion,up-regulated the STMN1,cyclin D1 and N-cadherin protein expression,and down-regulation of E-cadherin protein expression(P<0.05).Dual luciferase reporter gene assay showed that circAPLP2 targeted at negative regulation of miR-455-3p expression,while miR-455-3p targeted at negative reg-ulation of STMN1 expression.Nude mouse transplantation experiment found that knocking down circAPLP2 affect-ed the growth of transplanted tumors,while miR-455-3p expression was up-regulated and STMN1 expression was down-regulated(P<0.05).Conclusions CircAPLP2 inhibits the proliferation,migration and invasion of colorectal cancer cell lines by regulating the miR-455-3p/STMN1 axis.

Objective To investigate the relationships of CXC motif chemokine ligand 10(CXCL10)and CC motif chemokine ligand 11(CCL11)in the peripheral blood with type 2 diabetic osteoporosis(T2DOP),and to construct a predictive model.Methods A total of 260 patients with type 2 diabetes mellitus(T2DM)were prospectively selected as the T2DM group.They were divided into T2DOP group(n=82)and non-T2DOP group(n=178)according to the occurrence of T2DOP.Additionally,68 healthy volunteers with physical examinations in the same period were se-lected as control group.Enzyme-linked immunosorbent assay was used to detect the levels of CXCL10 and CCL11 in the peripheral blood as well as bone metabolism indicators[β-C-terminal te-lopeptide of type Ⅰ collagen(β-CTX),N-terminal propeptide of type Ⅰ procollagen(PⅠNP)].Pear-son correlation analysis was used to explore the correlation of CXCL10 and CCL11 in peripheral blood with bone metabolism indicator levels in patients with T2DM.Multifactor non-conditional Logistic regression analysis was used to explore the influencing factors of T2DOP and construct a pre-dictive model.The Hosmer-Lemeshow(H-L)test was used to assess the goodness of fit.The re-ceiver operating characteristic(ROC)curve analysis was used to evaluate the predictive value of each indicator and the predictive model for T2DOP,and decision curve analysis and Bootstrap resa-mpling were used for internal validation.Results Compared with the control group,the levels of CXCL10 and CCL11 in the peripheral blood as well as β-CTX in the T2DM group were significantly increased,while the level of P Ⅰ NP was significantly decreased(P＜0.05).Pearson correlation a-nalysis showed that CXCL10 and CCL11 in the peripheral blood in patients with T2DM were posi-tively correlated with β-CTX level(r=0.786,0.816,P＜0.001)and negatively correlated with P ⅠNP level(r=-0.675,-0.716,P＜0.001).Compared with the non-T2DOP group,the T2DOP group had significantly increased age and the ratio of diabetic nephropathy,prolonged dura-tion of diabetes,decreased body mass index(BMI)and P ⅠNP levels,and increased fasting blood glucose,glycated hemoglobin(HbA1c),β-CTX,CXCL10,and CCL11 levels(P＜0.05).Non-conditional Logistic regression analysis showed that advanced age,long duration of diabetes,high HbA1c,high CXCL10,and high CCL11 were independent risk factors for T2DOP(P＜0.05),while high BMI was an independent protective factor(P＜0.05).The ROC curve showed that the area under the curve(AUC)of the predictive model for predicting T2DOP was 0.919,which was significantly greater than the AUCs of 0.643,0.742,0.654,0.715,0.759 and 0.741 respectively for age,duration of diabetes,BMI,HbA1c,CXCL10 and CCL11 alone(Z=7.468,5.400,7.415,6.365,5.242,5.800,P＜0.001).After internal validation,the decision curve of the predictive model was higher than the two extreme curves.After 1,000 times of Bootstrap resampling internal validations,the concordance index of the predictive model was 0.919(95％CI,0.914 to 0.923).Conclusion Increased levels of CXCL10 and CCL11 in the peripheral blood are associat-ed with T2DOP,and the predictive model constructed based on these factors has a high predictive value for T2DOP.

Objective To establish a method for determining hydrogen sulfide(H2S)in blood and apply it to practical cases.Methods A delute solution was achieved by adding 0.8 mL saturated borax solution into 0.2 mL blood sample was diluted with.1 mL acetonitrile solution containing 0.1％formic acid was then taken in a test tube,followed by adding 0.1 mL dilute solution and 0.1 mL thiozine aqueous solution(1％).After thorough mixing,the mixture was left to stand for 30 minutes.Subsequently,the sample was subjected to liquid chromatography-tandem mass spectrometry(LC-MS/MS)analysis after centrifugation and membrane filtration.Results The results showed that H2S exhibited good linearity within the concentration range of 10～2 000 ng/mL,with the R2 value of 0.998 5.The detection limit was 5 ng/mL,and the quantification limit was 10 ng/mL.In three cases of H2S poisoning,sulfur ions were detected in the blood of the deceased individuals,with concentrations ranging from 0.17 to 0.56 μg/mL.Conclusion For the first time,this study established a LC-MS/MS method for determining H2S in blood,which can meet the detection needs of H2S poisoning cases.

Objective:With the in-depth study of complement dysregulation,glomerulonephritis with dominant C3 has received increasing attention,with a variety of pathologic types and large differences in symptoms and prognosis between pathologic types.This study analyzes the clinical,pathological,and prognostic characteristics of different pathological types of glomerulonephritis with dominant C3,aiming to avoid misdiagnosis and missed diagnoses. Methods:The clinical,pathological,and follow-up data of 52 patients diagnosed as glomerulonephritis with dominant C3 by renal biopsy from June 2013 to October 2022 were retrospectively analyzed.According to the clinical feature and results of pathology,15 patients with post-infectious glomerulonephritis(PIGN)and 37 patients with of non-infectious glomerulonephritis(N-PIGN)were classified.N-PIGN subgroup analysis was performed,and 16 patients were assigned into a C3-alone-deposition group and 21 in a C3-dominant-deposition group,or 27 in a C3 glomerulopathy(C3G)group and 10 in a non-C3 nephropathy(N-C3G)group. Results:The PIGN group had lower creatinine values(84.60 μmol/L vs 179.62 μmol/L,P= 0.001),lower complement C3 values(0.36 g/L vs 0.74 g/L,P<0.001)at biopsy,and less severe pathological chronic lesions compared with the N-PIGN group.In the N-PIGN subgroup analysis,the C3-dominant-deposition group had higher creatinine values(235.30 μmol/L vs 106.70 μmol/L,P=0.004)and higher 24-hour urine protein values(4 025.62 mg vs 1 981.11 mg,P=0.037)than the C3-alone-deposition group.The prognosis of kidney in the PIGN group(P=0.049),the C3-alone-deposition group(P=0.017),and the C3G group(P=0.018)was better than that in the N-PIGN group,the C3-dominant-deposition group,and the N-C3G group,respectively. Conclusion:Glomerulonephritis with dominant C3 covers a variety of pathological types,and PIGN needs to be excluded before diagnosing C3G because of considerable overlap with atypical PIGN and C3G;in addition,the deposition of C1q complement under fluorescence microscope may indicate poor renal prognosis,and relevant diagnosis,treatment,and follow-up should be strengthened.
