Objective: To analyze the prevalence status and clustering patterns of risk factors for chronic diseases among adult residents in Rui' an City, Zhejiang Province, so as to provide a basis for formulating strategies for the prevention and control of chronic diseases and implementing risk factor interventions. Methods: A multi-stage random cluster sampling method was used to select residents aged ≥18 years in 5 townships (sub-districts) of Rui' an City as survey subjects from December 2023 to March 2024. Data on basic information, history of major chronic diseases, lifestyle behaviors, height, weight, and blood biochemical indicators were collected through questionnaire surveys, physical examinations, and laboratory tests. Descriptive analysis was used to analyze the prevalence status of 5 risk factors for chronic diseases. K-means clustering analysis was used to analyze clustering patterns. Results: A total of 3 060 people were surveyed, including 1 476 males, accounting for 48.24%, and 1 584 females, accounting for 51.76%. The median age was 49.00 (interquartile range, 25.00) years. There were 1 275 cases (41.67%) of hypertension, 462 cases (15.10%) of diabetes, and 1 460 cases (47.71%) of dyslipidemia. Insufficient fruit and vegetable intake, excessive salt intake, overweight and obesity, excessive red meat intake, and smoking involved 2 201, 1 878, 1 541, 1 337, and 571 people, with prevalences of 71.93%, 61.37%, 50.36%, 43.69%, and 18.66%, respectively. K-means clustering analysis identified 4 clustering patterns: smoking-insufficient fruit and vegetable intake type (249 people, accounting for 8.20%), low intake type (1 421 people, accounting for 46.75%). high red meat type (245 people, accounting for 8.07%), and high BMI-high salt type (1 118 people, accounting for 36.96%). The prevalences of hypertension and diabetes were higher in adult residents of the high BMI-high salt type, at 56.53% and 20.30%, respectively. The prevalence of dyslipidemia was higher in adult residents of the smoking-insufficient fruit and vegetable intake type, at 59.44%. Conclusions The prevalence of insufficient fruit and vegetable intake among adult residents in Rui' an City is relatively high. The clustering pattern of chronic disease risk factors is dominated by the low intake type. The prevalence of chronic diseases is higher in adult residents of the high BMI-high salt type and smoking-insufficient fruit and vegetable intake type. It is suggested to carry out health education and collaborative intervention of risk factors for different risk groups.

Objective To explore the efficiency improvement in segmenting neural network with the application of Transformer + U-Net artificial intelligence (AI) and modeling with the application of Python scripts in three-dimensional (3D) printing brachytherapy. Methods A Transformer + U-Net AI neural network model was constructed, and Adam optimizer was used to ensure rapid gradient descent. Computed tomography or magnetic resonance imaging data of patients were standardized and processed as self-made data sets. The training set was used to train AI and the optimal result weight parameters were saved. The test set was used to evaluate the AI ability. Python programming language was used to write an automated script to obtain the output segmentation image and convert it to the STL file for import. The source applicator and needle could be automatically modeled. The time of automatic segmentation and modeling and the time of manual segmentation and modeling were entered by two people, and the difference was verified by paired t-test. Results Dice similarity coefficient (DSC), mean intersection over union (MIOU), and Hausdorff distance (HD95) were used for evaluation. DSC was 0.9341, MIOU was 0.8762, and mean HD95 was 2.516. The mean time of manual segmentation was 1187 s, and the mean time of AI segmentation was 145 s (P < 0.01). The mean time of manual modeling was 321 s, and the mean time of modeling with Python automated scripts was 18 s (P < 0.01). Conclusion The application of Transformer + U-Net automatic segmentation and Python automated scripts can effectively improve work efficiency in the 3D printing brachytherapy for cervical cancer.

BACKGROUND: The optimal antidepressant dosages remain controversial. This study aimed to analyze the efficacy of antidepressants and characterize their dose-response relationships in the treatments of major depressive disorders (MDD). METHODS: We searched multiple databases, including the Embase, Cochrane Central Register of Controlled Trials, PubMed, and Web of Science, for the studies that were conducted between January 8, 2016, and April 30, 2023. The studies are double-blinded, randomized controlled trials (RCTs) involving the adults (≥18 years) with MDD. The primary outcomes were efficacy of antidepressant and the dose-response relationships. A frequentist network meta-analysis was conducted, treating participants with various dosages of the same antidepressant as a single therapy. We also implemented the model-based meta-analysis (MBMA) using a Bayesian method to explore the dose-response relationships. RESULTS: The network meta-analysis comprised 135,180 participants from 602 studies. All the antidepressants were more effective than the placebo; toludesvenlafaxine had the highest odds ratio (OR) of 4.52 (95% confidence interval [CI]: 2.65-7.72), and reboxetine had the lowest OR of 1.34 (95%CI: 1.14-1.57). Moreover, amitriptyline, clomipramine, and reboxetine showed a linear increase in effect size from low to high doses. The effect size of toludesvenlafaxine increased significantly up to 80 mg/day and subsequently maintained the maximal dose up to 160 mg/day while the predictive curves of nefazodone were fairly flat in different dosages. CONCLUSIONS: Although most antidepressants were more efficacious than placebo in treating MDD, no consistent dose-response relationship between any antidepressants was observed. For most antidepressants, the maximum efficacy was achieved at lower or middle prescribed doses, rather than at the upper limit.

OBJECTIVE To observe the clinical efficacy of Maitong Jun'an Decoction in treating coronary heart disease(CHD)angina of qi deficiency and blood stasis type,and preliminarily elucidate its possible mechanism of action through transcriptomics meth-ods.METHODS A total of 140 patients with CHD angina of qi deficiency and blood stasis type were included and randomly divided into a treatment group and a control group,with 70 cases in each group.During the treatment period,3 patients in the control group dropped out.The control group received basic Western medicine treatment for secondary prevention of CHD,while the treatment group received Maitong Jun'an Decoction in addition to the treatment in the control group.The treatment period for both groups was 8 weeks.Before and after treatment,the patients in both groups were evaluated for the TCM syndrome score,Canadian Cardiovascular Society(CCS)angina grading,Seattle angina questionnaire(SAQ)score,self-rating anxiety scale(SAS),self-rating depression scale(SDS)score,and adverse reactions.The peripheral blood of 9 patients before and after treatment was selected for transcriptomic sequencing based on the principle of gender,age,and disease duration matching.RESULTS After treatment,the TCM syndrome scores and total scores of the 2 groups were significantly reduced(P<0.01).The treatment group was better than the control group in improving chest pain,chest tightness,shortness of breath,fatigue and total score(P<0.05,P<0.01);the overall improvement rate of CCS angina grading in the treatment group was better than that in the control group(P<0.05);the SAQ,SAS and SDS scores of the 2 groups were significantly reduced before and after treatment(P<0.01),and the SAQ score of the treatment group was improved better than that of the control group(P<0.05,P<0.01).The transcriptomics results showed that there were 862 significantly different mR-NAs before and after treatment,including 509 up-regulated and 353 down-regulated.GO analysis showed that there were 666 biologi-cal processes in the differentially expressed mRNAs,mainly including viral gene expression,translation initiation,RNA catabolism,etc.There were 112 cell components,mainly including focal adhesion,ribosome subunit,nuclear spot,etc.There were 94 molecular functions,mainly including double-stranded RNA binding,cadherin binding,transcription co-regulatory factor activity,etc.KEGG analysis showed that the differentially expressed mRNAs enriched in 20 signaling pathways,mainly including glycerophospholipid me-tabolism pathway,AMPK signaling pathway,ribosome pathway,etc.CONCLUSION Maitong Jun'an Decoction can improve clini-cal symptoms in patients with CHD angina of qi deficiency and blood stasis type.Its mechanism of action is multi-target and multi pathway,mainly related to the regulation of glycerophospholipid metabolism pathway,AMPK signaling pathway,ribosome pathway.

Objective:To investigate the rates of low disease activity and clinical remission in patients with systemic lupus erythematosus(SLE)in a real-world setting,and to analyze the related factors of low disease activity and clinical remission.Methods:One thousand patients with SLE were enrolled from 11 teaching hospitals.Demographic,clinical and laboratory data,as well as treatment regimes were collec-ted by self-completed questionnaire.The rates of low disease activity and remission were calculated based on the lupus low disease activity state(LLDAS)and definitions of remission in SLE(DORIS).Charac-teristics of patients with LLDAS and DORIS were analyzed.Multivariate Logistic regression analysis was used to evaluate the related factors of LLDAS and DORIS remission.Results:20.7％of patients met the criteria of LLDAS,while 10.4％of patients achieved remission defined by DORIS.Patients who met LLDAS or DORIS remission had significantly higher proportion of patients with high income and longer disease duration,compared with non-remission group.Moreover,the rates of anemia,creatinine eleva-tion,increased erythrocyte sedimentation rate(ESR)and hypoalbuminemia was significantly lower in the LLDAS or DORIS group than in the non-remission group.Patients who received hydroxychloroquine for more than 12 months or immunosuppressant therapy for no less than 6 months earned higher rates of LLDAS and DORIS remission.The results of Logistic regression analysis showed that increased ESR,positive anti-dsDNA antibodies,low level of complement(C3 and C4),proteinuria,low household in-come were negatively related with LLDAS and DORIS remission.However,hydroxychloroquine usage for longer than 12 months were positively related with LLDAS and DORIS remission.Conclusion:LLDAS and DORIS remission of SLE patients remain to be improved.Treatment-to-target strategy and standar-dized application of hydroxychloroquine and immunosuppressants in SLE are recommended.

Objective:To systematically evaluate the clinical efficacy of Ruiyun procedure for hemorrhoids(RPH)combined with milligan-morgan hemorrhoidectomy(MMH)in the treatment of mixed hemorrhoids compared with MMH alone.Methods:Relevant literature was retrieved from China National Knowledge Infrastructure(CNKI),Wanfang,and VIP databases from their establishment to Jan 2023 using computers.Clinical randomized controlled trials(RCTs)of RPH combined with MMH and MMH alone in the treatment of mixed hemorrhoids were selected and analyzed,and meta-analysis was conducted using RevMan5.3 software.Results:A total of 30 RCTs were included,involving 4 609 patients.Results of Meta-analysis showed that there were statistically significant differences in surgical efficacy(RR=1.05,95% CI:1.02-1.08,P= 0.003),postoperative margin edema(RR=0.36,95% CI:0.27-0.49,P＜0.01),postoperative anal pain(RR=0.35,95% CI:0.23-0.53,P＜0.01),postoperative rectal bleeding(RR=0.35,95% CI:0.17-0.72,P=0.004),postoperative anal stenosis(RR=0.26,95% CI:0.11-0.59,P=0.001)and postoperative urinary retention(RR=0.77,95% CI:0.63-0.93,P=0.007)between RPH combined with MMH group and MMH group.Conclusion:Compared with MMH alone,RPH combined with MMH in the treatment of mixed hemorrhoids can reduce the incidence of postoperative side effects,such as postoperative margin edema,anal pain,rectal bleeding,anal stenosis,and urinary retention,with a relatively higher efficiency.

Objective To analyze the epidemiological characteristics of occupational hand-arm vibration disease (OHAVD) in Guangdong Province from 2006 to 2022. Methods The data of newly reported OHAVD cases and suspected occupational disease cases in Guangdong Province from 2006 to 2022 was collected from the Report Card of Occupational Diseases and Report Card of Suspected Occupational Diseases using Occupational Diseases and Health Hazard Factors Monitoring Information System under China Disease Prevention and Control Information System. Epidemiological characteristics of the newly reported OHAVD cases and related suspected occupational disease reports were analyzed. Results A total of 660 newly reported OHAVD cases were reported in Guangdong Province from 2006 to 2022. The number of cases showed a periodic fluctuating trend over the years. Males accounted for 98.64% of the newly reported OHAVD cases with a median age of 38 years and a median hand-transmitted vibration exposure period of 8.7 years. These cases were predominantly distributed in the Pearl River Delta region, including Zhongshan City, Dongguan City, Guangzhou City, Shenzhen City and Foshan City, accounting for 99.25%. The manufacturing enterprises had 98.79% of the cases, investment enterprises of Hong Kong, Macao and Taiwan merchants of China had 83.18% of the cases, and large- and medium-sized enterprises had 92.73% of the cases. The 660 cases were distributed in 440 enterprises, but there were some characteristics of group outbreaks. There were 20 enterprises (4.55% of the total number of enterprises) had more than three cases involving 219 cases (33.18%). There were five enterprises which had more than 10 cases and the cases number ranged from 12 to 56. Among 382 newly reported OHAVD cases from 2014 to 2022, 44.24% were identified as suspected occupational diseases before diagnosis, of which 59.76% (101/169) were determined by occupational health inspection institutions. Conclusion Newly reported OHAVD cases in Guangdong Province were aggregated in terms of regional distribution, industry, enterprise ownership, and enterprise scale, with a risk of group outbreaks. It is suggested to enhance the OHAVD prevention and control in male workers exposed to hand-transmitted vibrations in the Pearl River Delta's manufacturing enterprises.

Objective:To evaluate the efficacy and safety of hypomethylating agents (HMA) in patients with myelodysplastic syndromes (MDS) .Methods:A total of 409 MDS patients from 45 hospitals in Zhejiang province who received at least four consecutive cycles of HMA monotherapy as initial therapy were enrolled to evaluate the efficacy and safety of HMA. Mann-Whitney U or Chi-square tests were used to compare the differences in the clinical data. Logistic regression and Cox regression were used to analyze the factors affecting efficacy and survival. Kaplan-Meier was used for survival analysis. Results:Patients received HMA treatment for a median of 6 cycles (range, 4-25 cycles) . The complete remission (CR) rate was 33.98% and the overall response rate (ORR) was 77.02%. Multivariate analysis revealed that complex karyotype ( P=0.02, OR=0.39, 95% CI 0.18-0.84) was an independent favorable factor for CR rate. TP53 mutation ( P=0.02, OR=0.22, 95% CI 0.06-0.77) was a predictive factor for a higher ORR. The median OS for the HMA-treated patients was 25.67 (95% CI 21.14-30.19) months. HMA response ( P=0.036, HR=0.47, 95% CI 0.23-0.95) was an independent favorable prognostic factor, whereas complex karyotype ( P=0.024, HR=2.14, 95% CI 1.10-4.15) , leukemia transformation ( P<0.001, HR=2.839, 95% CI 1.64-4.92) , and TP53 mutation ( P=0.012, HR=2.19, 95% CI 1.19-4.07) were independent adverse prognostic factors. There was no significant difference in efficacy and survival between the reduced and standard doses of HMA. The CR rate and ORR of MDS patients treated with decitabine and azacitidine were not significantly different. The median OS of patients treated with decitabine was longer compared with that of patients treated with azacitidine (29.53 months vs 20.17 months, P=0.007) . The incidence of bone marrow suppression and pneumonia in the decitabine group was higher compared with that in the azacitidine group. Conclusion:Continuous and regular use of appropriate doses of hypomethylating agents may benefit MDS patients to the greatest extent if it is tolerated.

Objective To construct and apply a management plan for microaspiration of oropharyngeal secretions in ICU intubated patients.Methods Based on evidence summaries and expert consultation,a management plan for microaspiration of oropharyngeal secretions in ICU intubated patients was constructed,consisting of 19 items covering 7 aspects including identification of risk factors,position management,tube and cuff selection,cuff management,mechanical ventilation management,pain and sedation management,removal of oropharyngeal and subglottic secretions,and oral care.Convenience sampling was used to select 141 ICU intubated patients from a tertiary A comprehensive hospital in Suzhou from June,2022 to September,2023.Patients were divided into an experimental group(n=72)and a control group(n=69)according to the wards.The experimental group received the management plan for microaspiration of oropharyngeal secretions in ICU intubated patients.The control group received the nursing bundle for ventilator associated pneumonia(VAP).The incidence and time from intubation to microaspiration and VAP,duration of mechanical ventilation,ICU length of stay,and disease outcome were compared between the 2 groups.Results The incidence of microaspiration of oropharyngeal secretions,the duration of mechanical ventilation,time from intubation to microaspiration showed significant differences between the 2 groups(P<0.05).There were no significant differences in the incidence of ventilator associated pneumonia,ICU length of stay,and disease outcome between the 2 groups(P>0.05).The time from intubation to VAP in the experimental group was 7.5 days,and that in the control group was 3.8 days.Conclusion The application of the management plan for microaspiration of orophaiyngeal secretions in ICU intubated patients is beneficial for reducing the incidence of microaspiration,delaying the time from intubation to microaspiration and VAP,and shortening the duration of mechanical ventilation.
