Objective To evaluate a model of management for chronic pain disease coordinated community health services and district hospital. Methods The epidemiology of chronic pain disease was surveyed in Haotao community of Zhongshan, before and after the establishment of the model of management. Results The prevalence rate of chronic pain disease was 51.83%, in which it was 47.06% in men, and 57.32% in women. After the establishment of the model, the efficacy of good to excellent improved from 30.22% to 67.08%, the cost for medicine reduced 36.16%, time for rest reduced from 32.42 d to 15.25 d (P<0.05). Conclusion The model of management that coordinated community health services and district hospital, including demonstration diagnosis and treatment through internet, tele-consultations and health education, is effective on chronic pain disease.

Objective To discuss the treatment and clinical results of acetabular fracture. Method Clinical data of 78 cases of acetabular fracture was analyzed retrospectively on treatment methods and clinical effects from August 1988 to December 2007, 41 cases were performed operation and 37 cases were performed non-operative management. Result The treatment effects were excellent in 43 cases, good in 22 cases, fair in 10 cases, poor in 2 cases and dead in 1 cases, with a good rate of 83.3%, and 20 cases had complications: 1 posterior dislocations of hip, 13 posttraumatic arthritis, 1 incisional infection, 5 ectopic ossi-fication. Conclusions It is very important to choose appropriate treatment methods by judging the real state of acetabular fractureexactly. Acetabular reconstruction plate is convenient, safe, and reliable in treat-ment of posterior wall and superior wall fractures.

Objective An attempt to develop a patient survey questionnaire on the public benefit nature of medical institutions as seen by patients,along with an evaluation of its reliability and validity.Methods A field survey was conducted among the patients visiting these institutions.The Cronbach's α coefficient was calculated to test the reliability.Factor analysis and spearman correlation analysis were applied to test the validity.The validity was also tested by analyzing the demographic factors and comparing the results between different kinds of medical institutions.Results The Cronbach's α coefficient of the questionnaire was 0.853,meanwhile the Cronbach's α coefficient of the three items was 0.845(quality of care),0.845 (suitability of services) and 0.752 (professional ethics).Three common factors were extracted,which coincided with the three items-quality of care,suitability of services and professional ethics.And the results are hardly affected by common demographic characteristics.Condusion The reliability of the questionnaire was acceptable,and the items were reasonably divided in the questionnaire with good structural validity.The questionnaire can be widely applied to evaluate the public benefit nature of medical institutions.

Objective To study the association of single nucleotide polymorphism (SNP) of the protein tyrosine phosphatase-1B (PTP-1B) gene with type 2 diabetes mellitus and obesity in Chinese. Methods SNPs in the PTP-1B gene were detected by direct sequencing to PCR products, and the detected SNPs were genotyped in case-spouse samples with the technique of fluorescence real-time PCR. Results Totally 6 SNPs were found in PTP-1B gene. Three SNPs (I5/37 C→A,I6/82 A→G, I7/301 C→T) were in the intron regions and the other 3 (E8/45 C→T, E9/35 G→A, E10/372 G→A)in the exon regions. Among them, E9/35 G→A was a newly found mutation site. The A allele frequency of I5/37 C→A, T allele frequency of I7/301 C→T and G allele frequency of I6/82 A→G in type 2 diabetes were significantly higher than those in the normal spouse group (P

To analyze and evaluate the knowledge of Chinese Guidelines of Diabetes Prevention and Treatment in Shanghai medical staff. 175 medical staff working in endocrinology or community health were enrolled and evaluated by a questionnaire of guidelines about the state of professional, training, and related knowledge. Only 16. 6% medical staffwere trained about the guidelines( 46. 67% from the general hospitals, 14. 75% from secod-level hospital and 7. 14% persons from the community hospitals, P＜0. 01 ). The total correct answer rate of the guidelines was 37. 36%. The correct rate of community hospitals was lower than others( P＜0. 05 ). The rate of doctors' was higher than nurses'( P＜0. 05 ). There were difference between doctors and nurses with the key point of diabetes care knowledge in different level hospitals. The effective method of clinical training in diabetes care should be explored. We still have to work hard to promote the effect of diabetes control and prevention. Effective training about the guidelines should be enhanced. The cooperation between general hospitals and community health institutions in diabetes prevention and treatment should be enhanced.

Since December 2019, an outbreak of novel coronavirus pneumonia (COVID-19) in Wuhan, Hubei Province, which has caused wide public concern all through the world. Although artificial intelligence is a priority development fields in recent years, there is no study on the application and effect of AI in this epidemic. Based on the application of AI scenarios in typical cases, the research analyzes the practice and effectiveness of AI in epidemic surveillance, clinical diagnose, public health management and other related scientific research. Besides, combined with the current situation of development, some suggestions are put forward in order to better play the role of artificial intelligence in the public health emergency system in China.
