Objective: To evaluate the effect of exercise prescription intervention among patients with type 2 diabetes mellitus (T2DM), so as to provide the evidence for guiding appropriate physical activity and glycemic control in this population. Methods: In July 2023, T2DM patients managed by two community health service centers in Qingjiangpu District, Huai'an City, Jiangsu Province, were selected as the study participants and randomly assigned divided into a control group and an intervention group. The control group received routine chronic disease management under the basic public health services, while the intervention group, in addition to receiving the same routine chronic disease management, was provided with exercise prescription to guide their physical activity at baseline (T0), after 3 months of intervention (T1), and after 6 months of intervention (T2). Data on weight-related indicators, glycated hemoglobin (HbA1c), and blood lipid were collected through physical examinations and laboratory tests at T0 and after 12 months of intervention (T3). The differences in indicators between the two groups before and after the intervention were analyzed using generalized estimating equations. Results: The intervention group consisted of 197 patients, including 99 males, accounting for 50.25%. The median disease duration was 7.10 (interquartile range, 7.80) years, and 113 patients had suboptimal HbA1c levels, accounting for 57.36%. The control group included 196 patients, including 99 females, accounting for 50.51%. The median disease duration was 6.10 (interquartile range, 7.00) years, and 100 patients had suboptimal HbA1c levels, accounting for 51.02%. Before the intervention, no statistically significant differences were observed between the two groups in gender, educational level, disease duration, pharmacological treatment, smoking, alcohol consumption, and HbA1c levels (all P>0.05). In the intervention group, the proportion of participants engaging in aerobic exercise and strength training increased from 78.17% and 8.12% at T0 to 85.79% and 16.24% at T3, respectively (both P<0.05). The results of the generalized estimating equations revealed significant interactions between group and time for waist-to-hip ratio, total cholesterol (TC), and low-density lipoprotein cholesterol (LDL-C) following the intervention (all P<0.05). A statistically significant difference in waist-to-hip ratio was found between the two groups (P<0.05), with a greater reduction observed in the intervention group compared to the control group. Significant differences in TC and LDL-C levels were noted across different intervention time points (both P<0.05). Specifically, the intervention group demonstrated reductions of 0.35 mmol/L in TC and 0.42 mmol/L in LDL-C from baseline to follow-up (both P<0.05). Conclusion The 12-month exercise prescription intervention can effectively enhance exercise participation and reduce waist-to-hip ratio, TC, and LDL-C levels among patients with T2DM.

Objective:To explore the marking method for magnetically controlled capsule gastroscopy (MCCG) pictures with artificial intelligence (AI), so as to improve the work efficiency of endoscopist and to reduce the blind area of AI image reading.Methods:According to the consensus of MCCG, 24 parts of stomach in 14 775 pictures of MCCG from 35 subjects in Shenzhen Zifu Medical Technology Co., Ltd received MCCG from March to August, 2020 were marked by ten gastroenterologists and one developer of MCCG with medical background, the marking shape included rectangles and polygons. Among the ten gastroenterologists, three were senior endoscopist (the total number of gastroenteroscopy operations over 80 000, chief physician or associate chief physician), four were medium seniority endoscopist (the total number of gastroenteroscopy operations between 10 000 and 80 000, associate chief physician), and three were junior endoscopist (the total number of gastroenteroscopy operations less than 10 000, attending physician). The pictures of the same subject were pre-marked by two selected senior endoscopists with blind method, and the standard of marking with most appropriate coincidence rate was determined. The qualified marked pictures were automatically learn with AI deep learning method, and the learning results were fed back. Chi square test was used for statistical analysis.Results:According to the pre-marked results, the standard of coincidence rate for rectangular marking area was set as 50.0% and that for polygon marking area was 70.0%. The first correction for qualified rate was 39.0% (5 762/14 775). A total of 9 013 pictures were corrected. After repeated training and correction for one to five times, all pictures were qualified marked. The marking qualified rate of senior endoscopist partners was higher than that of partners of different qualifications (48.7%, 1 200/2 466 vs. 19.0%, 825/4 337), and the difference was statistically significant ( χ2=659.20, P<0.001). There was no statistically significant difference in the marking qualified rate between the senior endoscopist partners and partners of senior endoscopist and capsule developer (48.7%, 1 200/2 466 vs. 49.6%, 1 496/3 019; P>0.05). Conclusions:Establishment of AI marking method for MCCG can provide technical support for AI non-blind area reading, and AI non-blind area monitoring during the operation of MCCG.

Objective:To identify human infection with Brucella suis, analyze its biological and molecular characteristics, and to provide basis for prevention and control of brucellosis. Methods:Brucella suis strains were isolated from the body of the first case of human Brucella suis infection in Jiangsu Province. Serum agglutination test was used for serotyping. The specific gene bcsp-31 of Brucella was detected by PCR. AMOS-PCR was used to identify IS-711. The species and biotypes were identified by multiplex PCR. The wboA gene products were sequenced and phylogenetic tree was constructed. Multilocus sequence analysis (MLSA) was used for molecular typing, and cluster analysis was performed with reference strains. Results:The strain was confirmed to be Brucella suis biotype 3 by serum agglutination test and PCR. After sequencing the wboA gene, cluster analysis of the reference sequence showed that the wboA gene was closest to the biotype 3 strain Brucella suis str. 686 (CP007719). MLSA was typed into ST17(1-6-4-1-5-3-5-2-4). Conclusions:Brucella suis biotype 3 is reported in Jiangsu Province for the first time. The MLSA type is ST17. In the future, the prevention and control of human brucellosis should be carried out. We should actively cooperate with the animal husbandry and veterinary department to increase the quarantine, immunization and other control measures.

Objective To analyze the current situation of the official micro-blogs of the health and family planning commissions of provincial level, and to understand its application approaches.Methods The internet crawler software was used to collect the 102 899 micro-blog posts published by 24 official micro-blogs of health and family planning commissions of provincial level,and analyze the information of crawling by using content analysis method.Results At present, except for a number of provinces in the eastern regions where such micro-blogs were active and interactive,most of these official micro-blogs were found poor in operation management, especially in the spreading capacity; their micro-blog content was focused on science popularization(59.50%).Part of the content lacked scientific basis,and was short of planning in their information release form and content.Conclusions These micro-blogs need optimization in operations management,service positioning,information release specifications,and content audit.Such efforts can help improve their spreading capacity,influence and user viscosity, in order to better serve the public, achieve the goal of a service-oriented government.

Objective To provide reference for service optimization of information suppliers and doctors through analyzing the residents'value cognition and utilization of online health information.Methods Questionnaires were distributed in June 2016 to 1 460 residents aged 18 or above and having experienced medical visits themselves or accompanying others in one year. They were surveyed to learn their health information cognition and utilization behavior. The data so acquired were subject to constituent ratio and Chi square test analysis. Results In terms of their use of online health information, 58.5% of the respondents would consult relevant information before medical visits, 64.3% would verify the doctor's diagnosis online following such visits. In case of any inconsistences, 28.2% of them would seek second opinion at another hospital. Statistical differences were discovered in the cognitive difference of residents of different sexes on "internet health information inquiry can relieve tension" , and in the utilization difference of residents of different ages and educational on " whether to consult online health information before medical visits" ( P<0.05). Conclusions The residents'value cognition of online health information is rational in general, but there are also some cognitive behaviors worthy of notice. Information conflicts may incur doctor-patient conflicts and repetitive medical visits. Stakeholders should ensure the professionalism and quality of the information providers. The doctors should master the communication skills and pay attention to the potential impact of online health information.

Objective To provide reference for bettering online health information supply and meeting residents' health needs by analyzing residents' access to and utilization rate of online health information. Methods 1 460 residents aged 18 years or above and having experienced medical visits themselves or accompanying others in one year were surveyed in June 2016. The survey covered their access to online health information and the utilization rate. χ2test, variance analysis, and important quadrant derivation model were used in the data analysis. Results 84.5% of the respondents used mobile phones as the most popular tool for accessing health information on the Internet, with more women than men. The importance quadrant analysis found that the residents have the highest utilization rate (72.6% ) of search engines, yet the reliability scoring of such engines was the lowest ( 62.8 ). Professional medical health websites scored the highest in reliability (81.8), yet the lowest utilization rate (2.1% ). Conclusions Search engines require stronger scrutiny to improve their information quality. Professional health and medical institutions'websites are encouraged to step up health information promotions, and health management Apps should be regulated in their development, to create convenient and reliable online health information platforms.

OBJECTIVETo assess the antibiotic resistance and molecular characterization of cholera strains and to provide basis for clinical treatment and prevention of cholera.

METHODS4 stains isolated from an outbreak of cholera epidemic in Huai'an City in Jiangsu province in September 2010 were characterized using antibiotic susceptibility, biotype analysis, virluence genes detection, ctxB gene sequencing, and PFGE analysis.

RESULTSThe 4 strains were all resistant to sulphamethoxazole/trimethoprim, erythromycin, streptomycin. High drug susceptibility of the samples was found to 6 kinds of antibiotics such as amikacin, norfloxacin, ciprofloxacin, gentamicin, chloramphenicol, ampicillin. The isolates expressed phenotypic traits of both serogroup O1 ogawa and El Tor and carried 9 kinds of virulence genes, ctxA, ace, zot, toxR, tcpI, ompU, rtxC, tcpA, and hlyA gene. They were also identified as harboring the classical ctxB genotype based on amino acid residue substitutions. The PFGE profiles of NotI showed a single banding pattern, while SfiI's was 2 banding patterns.

CONCLUSIONThe bacterium type of Vibrio cholerae causing the epidemic outbreak of cholera belonged to the atypical EL Tor variant which was also identified as toxicogenic strain. The mapping of the strains prompted that there should be the common contamination source. Drug sensitivity test can guide the clinical drug use, in order to reduce the emergence of resistant strains.
