Objective:To analyze the association between healthy lifestyle and mortality among Henan Province 35-74 years old individuals.Methods:Data from the programme of screening and intervention subjects with high-risk cardiovascular disease 99 133 adults were analyzed in a provincial cohort study of 16 counties. Four healthy lifestyle behaviors were assessed based on a questionnaire survey. Information on mortality endpoints was retrieved from the national death surveillance system. Cox proportional hazards regression models were used to estimate the associations between healthy lifestyles, mortality risk and population attributable fraction (PAF).Results:Out of the adult participants in Henan, 50.6% adhered to a healthy lifestyle, and only 0.1% adhered to 4 healthy lifestyle behaviours. During a mean of 4.5 years, 2 685 all-cause death and 1 283 cardiovascular deaths were documented. The decreased risk of mortality among individuals with non-smoking, moderate drinking, adequate exercise and healthy diet were 0.85 (95% CI: 0.77-0.94), 0.75 (95% CI: 0.63-0.89), 0.73 (95% CI: 0.67-0.79) and 0.86 (95% CI: 0.77-0.96), while the adjusted PAF for all-cause deaths were 5.2% (95% CI: 2.5%-7.9%), 24.0% (95% CI: 10.7%-36.4%), 19.4% (95% CI: 13.8%-24.8%) and 12.3% (95% CI: 3.4%-20.9%), respectively. A combined healthy lifestyle can bring more health benefits. Adherence to 4 healthy lifestyle behaviours could avoid 49.1% of all-cause death. Conclusion:Adherence to a healthy lifestyle can reduce the risk of death, and participants with a healthy lifestyle had a lower mortality risk.

Objective:To assess the association between blood pressure and the risks of diabetes mellitus.Methods:Screening and intervention were conducted from 2015 to 2019 for high-risk subjects of cardiovascular diseases in eight counties of Henan. Information on demographic characteristics, lifestyle behaviors, and anthropometric measurements were obtained via a questionnaire. Fasting blood samples were collected for blood glucose and serum lipids. The R 3.6.3 software was used to analyze the relationship between blood pressure and diabetes mellitus.Results:The detection rate of diabetes mellitus was 23.5% among 120 040 participants aged 35-75 years. The mean fasting blood glucose level was significantly different among normotensive, prehypertensive, and hypertensive patients. Compared to normotensive patients, prehypertension and hypertension had adjusted ORs of 34%( OR=1.34, 95 CI%: 1.30-1.37) and 85%( OR=1.85, 95 CI%: 1.81-1.89). The corresponding ORs were 1.81(1.77-1.85) in controlled and 2.17(2.06-2.28) in uncontrolled patients. A subgroup analysis showed the same trend, where the risk of diabetes increased with blood pressure ( P<0.05). Conclusions:People with elevated BP may increase their risk of diabetes, while the risk declines when BP is under control. Therefore, targeted measures should be taken to reduce the risk.

Objective:To compare the differences of prostate cancer (PCa) and clinically significant prostate cancer (CsPCa) positive rate and postoperative complications between transperineal cognitive prostate biopsy (COG-TPBx) and transrectal cognitive prostate biopsy (COG-TRBx) based on biparametric magnetic resonance imaging (bpMRI).Methods:The data of 276 patients undergoing prostate biopsy from January 2019 to June 2021 in the First Affiliated Hospital of Nanjing Medical University were retrospectively reviewed. 157 patients underwent COG-TPBx(TPBx group) and 119 patients underwent COG-TRBx (TRBx group). The average age [(66.39 ± 8.31) vs. (66.30 ± 8.42)years], body mass index (BMI) [(23.85±2.49) vs. (23.68±2.61) kg/m 2], PSA values [9.43(1.47-19.80) vs. 8.94(0.66-19.99) ng/ml], prostate volume [37.92(13.99-167.40) vs. 40.78(11.67-188.21) cm 3], PSA density [0.21(0.04-1.17) vs. 0.20(0.04-1.04) ng/(ml·cm 3)], and suspicious digital rectal examination [17.20% (27/157) vs. 21.10% (25/119) ] were not significantly different between TPBx group and TRBx group. The positive rate of PCa, CsPCa, as well as post-biopsy complications of the two groups were compared. Results:There were no significant differences in the positive rate of PCa [49.68%(78/157) vs. 47.06%(56/119), P=0.666] and CsPCa [38.22%(60/157) vs. 34.45%(41/119), P=0.520] between the two groups. In stratification analysis, TPBx group has a significantly higher positive rate of both PCa [54.69%(35/64)] and CsPCa[43.75%(28/64)] in apex zone than TRBx group[39.62%(21/53) and 20.75%(11/53), all P<0.05). Moreover, the postoperative complications were not significantly different in TPBx group compared to that in TRBx group [10.19% (16/157) vs. 12.61%(15/119), P= 0.567]. Conclusions:Our investigations revealed that the overall positive rate of PCa, CsPCa, and the complications were not statistically different between COG-TPBx and COG-TRBx. COG-TPBx has a significantly higher positive rate of both PCa and CsPCa in apex zone.

Objective:To detect the value of utilizing bpMRI in prostate biopsy in the detection of prostate cancer with PSA≤20ng/ml.Methods:The clinical data of 394 patients who underwent prostate biopsy in the First Affiliated Hospital of Nanjing Medical University from November 2017 to October 2019 were retrospectively analyzed. Of all the patients, 177 underwent modified systematic biopsy, named TRUS group, 217 patients accepted pre-biopsy bpMRI examination, undergoing modified systematic biopsy if Prostate Imaging Reporting and Data System (PI-RADS) score < 3 or MRI-TRUS cognitive fusion targeted prostate + systematic biopsy if PI-RADS score ≥ 3, named MRI group. The median age of TRUS group was 66 (61, 74) years old, prostate specific antigen (PSA) was 9.52 (7.26, 12.30) ng / ml, and prostate volume (PV) was 36.84 (28.95, 57.72)ml. The median age of MRI group was 66 (59, 72) years old, PSA was 8.84 (6.65, 12.16) ng/ml, and PV was 39.45 (29.25, 58.69)ml. There was no difference in above parameters between the two groups. The χ 2 test was used to compare the detection rate of prostate cancer and clinically significant prostate cancer (CsPCa) between the two groups. Results:There was no significant difference in the detection rates of prostate cancer between TRUS group and MRI group [51.41% (91/177) vs. 48.39% (105/ 217), P = 0.550], but the detection rates of CsPCa were significantly different [26.55% (47/177) vs. 36.41% (79/217), P = 0.037]. In patients with PSA ≤ 10 ng / ml, there was no significant difference in the detection rates of prostate cancer between the two groups [43.62% (41/94) vs. 43.08% (56/130), P = 0.936], but there was a significant difference in the detection rates of CsPCa [17.02% (16/94) vs. 28.46% (37/130), P = 0.047]. There was no significant difference in the detection rates of prostate cancer [60.24% (50/83) and 56.17% (48/87), P= 0.504] and the detection rates of CsPCa [37.35% (31/83) vs. 48.28% (42/87), P = 0.150] between the two groups. The total detection rates of the last two needles in TRUS group and MRI group were 23.16% (41/177) and 36.63% (86/217), respectively, with significant difference ( P=0.001); the detection rates of CsPCa in the last two needles were 11.86% (26/177) and 29.03% (63/ 217), respectively, with significant difference ( P < 0.001). In MRI group, the detection rates of prostate cancer in patients with PI-RADS score <3, 3, 4, 5 were 21.21% (7/33), 25.84% (23/89), 73.24% (52/71), 95.83% (23/24), respectively; the detection rates of CsPCa were 12.12% (4/33), 17.98% (16/89), 54.93% (39/71), 83.33% (23/24), respectively. Conclusions:In patients with PSA ≤ 20 ng / ml, prostate biopsy based on bpMRI may improve the detection of CsPCa, especially in patients with PSA ≤ 10 ng/ml.

Objective To explore the clinical feature,treatment and prognosis of incidental prostate cancer(IPC) after transurethral resection of the prostate (TURP) for benign prostatic hyperplasia (BPH).Methods From January 2009 to April 2017,24 cases undergoing TURP for benign prostatic hyperplasia and being diagnosed with prostate cancer(T1a-T1b) was retrospectivey analysed,who aged from 62 to 84 years (mean 71.8 years).Digital rectal examination (DRE) showed prostate medium texture,smooth surface,and no nodules.Ultrasound presented no low echo nodules in the prostate.Prostate volumes were 19.2-93.4 ml,with median of 40.1 ml.PSA were 1.81-9.11 ng/ml,with median of 4.12 ng/ml.The patients with PSA between 6-10 ng/ml accepted prostate biopsy,and pathological results were negative.Results The The pathology of TURP specimens in 24 cases were diagnosed prostate cancer (21 cases of T1a,3 cases of T1b).According to the new WHO/ISUP classification group,there were 18 cases of hierarchical group 1,3 cases of hierarchical group 2,1 case of hierarchical group 3,2 cases in hierarchical group 4.All patients were treated with hormonal therapy,and 7 cases (5 cases of hierarchical group 1,and 2 cases of hierarchical group 2) underwent laparoscopic radical prostatectomy (LRP) after 3 months of hormonal therapy.The specimens of prostatectomy were examined by whole-mount serial,showing 3 cases of prostate cancer (T1a) with negative margin,and 4 cases of benign prostate cells.They were followed up for 5-82 months with median of 43.5 months.No biological progression or tumor progression was found,and,1 case died of colon cancer after 26 months of follow-up.The patients' age and Gleason score of stage T1b were higher than that of stage T1a.Prostate volume and preoperative PSA had no statistically significant difference between the two stages.Conclusions The patients' age and Gleason score of stage T1b were higher than that of stage T1b.The proportion of residual tumor following TURP was high.The prognosis of incidental prostate cancer was good by hormonal therapy or radical prostatectomy.

Objective To explore the framework of organization and management of community health service institution in Changning district.Methods A questionnaire survey was conducted among 30 managers of 10 community health service centers in Changning district at October 2015.The questionnaire included the basic situation of the community health service institution,the operation of the current organization and management framework,and the intention of further adjustment.Results There were 5 systems (administration system,family doctor team system,inpatient system,support system and medical technical system) in current organization and management structure.Twenty seven responders (93.1％) thought that the bottlenecks and problems existed in the current organization structure (22 thought that the responsibilities of the organization and management system were unclear and overlapped;22 thought that the cooperation and coordination between systems were less strong;10 thought that organization systems had poor mutual understanding and consistency of action,2 mentioned other problems).Twenty five responders (86.2％) thought that the bottlenecks and problems existed in the current management structure (18 thought that the current management model was difficult to promote reform or new work;14 thought that there were more layers of management and less managerial efficiency;13 thought that there was lack of effective management measures;4 mentioned other problems).Twenty nine responders proposed suggestions dealing with the service function,management function,service organization form and new organization and management framework of community health service institutions.The family doctor studio as the core of service platform and management platform was recommended.Conclusions There are problems and bottlenecks in the current organization and management framework of community health service institutions in Changning district,and a new framework has been proposed according to the management recommendations.

The first family doctor studio was established at 2011 in Shanghai,afterwards a wide variety of family doctor studios were set up over the country.Family doctor studio has been become a significant form and carrier to promote the family doctor service.However,there are still lacks of unified standards and perfect mechanisms for its operation and evaluation.To adapt the reform of community health service,it is urgent to standardize the family doctor studio,to promote the development of the community health service and the reform of the family doctor system.Based on Zhoujiaqiao mode,Changning District has kept exploring the operation mechanism,standardizing the management and service mode,and promoting brand building of the family doctor studio since 2012.The service mode and operation mechanism of family doctor studio with Changning characteristics has gradually formed.This article summarizes the construction,development and improvement of the family doctor studio.

Background and purpose:Cancer is a major public health issue in China and worldwide, which se-riously threatens human beings as well as social and economic development. This study explored the relationships between the cancer distribution characteristics and cancer prevalences in Chinese cancer surveillance regions to provide scientific evidence for cancer prevention and management.Methods:The data were obtained from the book named“Prevalence and Mortality of Cancer in China from 2003-2007” including incidence of 23 cancer types in 32 regions of China published by the Academy of Military Medical Sciences of the Chinese PLA in 2012. Correspondence analysis was used to gain the relation between the prevalence and area distribution. Cluster analysis was used to obtain the classifications with special significance by putting the cancers or regions with similar characteristics into a cluster.Results:Esophageal cancer, gastric cancer, liver cancer, lung cancer, colorectal and anal cancer have high incidence and mortality in both genders. The districts with high incidence of esophageal cancer and gastric cancer were grouped together. The counties or cities (Shexian, Yangcheng, Linzhou, Yanting, Yangzhong and Jianhu) with high incidence of esophageal cancer and gastric cancer were classified into same cluster frequently. Fusui was grouped along because of the lower incidence of various cancers than the national average except for liver cancer. Guangzhou, Sihui and Zhongshan were the districts with high incidence of nasopharyngeal carcinoma in both genders. Rural areas in Qidong and Haimen were classified into a cluster in male and total data for the high incidence of liver cancer. Colorectal cancer, anal cancer and breast cancer in women also had high incidence in urban areas. Cervical cancer had the second level high incidence in women following diseases of digestive system, breast cancer and lung cancer.Conclusion:Similar pathogenic factors may exist in counties or cities of Shexian, Cixian, Yangcheng,etc, because of the high prevalence of esophageal cancer. Similar pathogenic factors may also exist in other districts or cancers that were classified into the same cluster.
