Objective To observe the therapeutic effects of recombinant human granulocyte colony stimulating factor(rhG-CSF)on CCl4 induced chronic liver injury.Methods Male BALB/C mice were randomly allocated into treatment and control groups.The mice model were established by injection with daily for 7 days,while the control mice were received the same volumes of saline.The mice were sacrificed to get weight,liver mass and spleen mass.The count of CD34+ cells and Thy-1+ cells were analyzed by flow cytometry and immunohistochemical staining,respectively.Results The ratio of liver/spleen was 15.94±1.20 and 10.52±0.66 on day 8 and 15 in treatment group,respectively,while those were 7.14±1.68 and 8.31±1.71 in control group,respectively(all P value＜0.05).But there was no significant difference in body weight and liver mass between two groups(P＞0.05)The concentration of album in treatment group was raised rapidly on day 15.The concentrations of alanine aminotransferase (ALT),aspartate aminotransferase(AST),hyaluronic acid(HA)and laminin(LN)on day 30 were significantly lower in treatment group compared to control group(P＜0.05).There was significant difference in score of liver fibrosis on day 30 between two groups(treatment group:5.49±2.16,control:8.74±1.86,P＜0.05).The number of CD34+ cell and Thy-1+ in treatment group(on day 8:9.54±2.24 and 5.10±1.25 and on day 15:8.18±1.93 and 7.53±1.39,respectively)were higher than those in control group(on day 8:5.40±0.99 and 3.25±0.75;on 15 days:4.46±0.77 and 3.35±0.86,all P value＜0.05).Conclusion The rhG-CSF may improve the reparation of chronic liver injury,and may provide a novel method in treatment of liver fibrosis.

CD4+CD25+ Regulatory T cells (Treg) have been found to down-regulate immune activation in HIV-1 infection. However, whether the depletion of Treg benefits to the disease status of HIV infection remains undefined. To address this issue, we enumerated the Treg absolute counts and frequency in 75 antiviral-na(i)ve HIV-1-infected individuals in this study. It was found that HIV-infected patients displayed a significant decline in Treg absolute counts but a significant increase in Treg frequency. In addition, with disease progression indicated by CD4 T-cell absolute counts, circulating Treg frequency gradually increased; while Treg absolute counts were gradually decreased, suggesting that the alteration of Treg number closely correlated with disease progression in HIV infection.Functional analysis further showed that Treg efficiently inhibit both CD4 and CD8 T cell proliferation in vitro. Thus, our findings indicates that Treg actively participate in pathogenesis of chronic HIV infection,influencing the disease progression.

Objective To develop a machine simultaneously integrating mechanized environmental cleaning and automatic mollusciciding and to evaluate its effectiveness of field application,so as to provide a novel Oncomelania hupensis snail control technique in the large?scale marshlands. Methods The machine simultaneously integrating mechanized environmental clean?ing and automatic mollusciciding,which was suitable for use in complex marshland areas,was developed according to the mech?anization and automation principles,and was used for O. hupensis snail control in the marshland. The effect of the machine on environmental cleaning and plough was evaluated,and the distribution of living snails was observed at various soil layers follow? ing plough. The snail control effects of plough alone and plough followed by mollusciciding were compared. Results The ma?chine could simultaneously complete the procedures of getting vegetation down and cut vegetation into pieces,plough and snail control by spraying niclosamide. After plough,the constituent ratios of living snails were 36.31% ,25.60% ,22.62% and 15.48% in the soil layers at depths of 0-5,6-10,11-15 cm and 16-20 cm respectively,and 61.91% living snails were found in the 0-10 cm soil layers. Seven and fifteen days after the experiment,the mortality rates of snails were 9.38% and 8.29% in the plough alone group,and 63.04% and 80.70% in the plough + mollusciciding group respectively(c27 d = 42.74,c215 d =155.56,both P values < 0.01). Thirty days after the experiment,the densities of snails were 3.02 snails/0.1 m2 and 0.53 snails/0.1 m2 in the soil surface of the plough alone group and the plough + mollusciciding group,which decreased by 64.92% and 93.60% ,respectively,and the decrease rate of snail density was approximately 30% higher in the plough + mollusciciding group than that in the plough alone group. Conclusions The machine simultaneously integrating mechanized environmental cleaning and automatic mollusciciding achieves the integration of mechanical environmental cleaning and automatic niclosamide spraying in the complex marshland areas,which provides a novel technique of field snail control in the large?scale setting in Chi?na.

Objective To evaluate the potential risk of schistosomiasis transmission in the area along the Yangtze River in Yangzhou City,so as to provide evidences for establishing a post?transmission surveillance system for schistosomiasis in marsh?land regions. Methods The water infectivity,floating boatmen and fishermen infection,reservoir host infection and wild feces contamination were investigated in five districts/counties along the Yangtze River in Yangzhou City,including Guangling,Hanji?ang,Jiangdu,Yizheng and Development Zone,and the transmission factors and risky characteristics were assessed after inter?ruption of schistosomiasis transmission in marshland regions. Results A total of 15 key water regions were identified in the area along the Yangtze River in Yangzhou City in 2015. A total of 1 500 sentinel mice were placed,after breeding,their overall sur?vival rate was 99.33%;1 490 were dissected,with no schistosome infection. Of the 5 576 floating boatmen and fishermen exam?ined,no schistosome infection was observed,and among the 3 566 domestic animals(including 171 cattle,1 895 sheep and 1 500 pigs),no infections were detected. During the period between January and March,2016,there were 3 200 mouse traps placed on 8 marshlands,and 62 wild mice were captured from 6 marshlands,with a capture rate of 1.94%,and no schistosome?infected wild mice were seen. In addition,there were 35 pieces of fresh wild feces captured from 7 marshlands,including 11 pieces of bovine feces(31.43%),17 pieces of sheep feces(48.57%),2 pieces of dog feces(5.71%)and 5 pieces of other feces (14.29%),and no infections were detected. Conclusions There is a low risk of schistosomiasis transmission in the area along the Yangtze River in Yangzhou City. However,the contamination of feces from bovine and sheep that are freely pastured on marshlands is a big threat to schistosomiasis control.

STUDY DESIGN: A prospective cross-sectional study. PURPOSE: To evaluate the risk factors associated with the severity of pain intensity in patients with non-specific low back pain (NSLBP) in Southern China. OVERVIEW OF LITERATURE: Low back pain (LBP) is the leading cause of activity limitation and work absence throughout the world, so a firm understanding of the risk factor associated with NSLBP can provide early and prompt interventions that are aimed at attaining long-term results. METHODS: Participants were recruited from January 2014 to January 2016 and were surveyed using a self-designed questionnaire. Anonymous assessments included Short Form 36-Item Health Survey (SF-36) and Visual Analogue Scale (VAS). The association between the severity of NSLBP and these potential risk factors were evaluated. RESULTS: A total of 1,046 NSLBP patients were enrolled. The patients with primary school education, high body mass index (BMI), those exposed to sustained durations of driving and sitting, smoking, recurrent LBP had increased VAS and Oswestry Disability Index (ODI) scores with lower SF-36 scores (p<0.01). Workers and drivers compared with waiters and patients who lifted >10 kg objects in a quarter of their work time for >10 years had higher VAS and ODI scores with lower SF-36 scores (p<0.01). Multiple logistic regression showed lower levels of education, LBP for 1–7 days, long-lasting LBP in last year, smoking, long duration driving, and higher BMI were associated with more severe VAS score. CONCLUSIONS: The severity of NSLBP is associated with lower levels of education, poor standards of living, heavy physical labor, long duration driving, and sedentary lifestyle. Patients with recurrent NSLBP have more severe pain. Reducing rates of obesity, the duration of heavy physical work, driving or riding, and attenuating the prevalence of sedentary lifestyles and smoking may reduce the prevalence of NSLBP.

Objective:To analyze the health literacy level among medical staff and its influencing factors.Methods:Using the convenient sampling method, the in-service medical staff from four medical institutions (Shanghai Pudong New Area People′s Hospital, Shanghai Pudong New Area Zhoupu Hospital, Shanghai Tenth People′s Hospital Chongming Branch, and Shanghai Jing′an District Zhabei Central Hospital) were administered with a national residents′ health literacy questionnaire uniformly compiled by the China Health Education Center, and an electronic questionnaire independently compiled in combination with professional characteristics of the medical staff. The survey period was January 5-17, 2021. The contents of the questionnaire included basic information regarding gender, age, education, and professional title. Respondents were also asked whether they had chronic diseases, and three aspects of health literacy for basic knowledge and concepts, healthy lifestyle and behavior and health skills covering six other types of health problems including scientific outlook on health, infectious disease prevention and control literacy, chronic disease prevention and control. Safety and first aid literacy, basic medical literacy, health information literacy were also assessed. The total score for the questionnaire was 100 points. Respondents with a score of 80 or more were considered to have a competent health literacy. A total of 870 questionnaires were distributed, excluding incomplete ones, 826 valid questionnaires were used for analysis. Logistic regression was used to analyze factors influencing the health literacy among medical staff.Results:The overall health literacy level of medical staff was 64.0%, with 79.7% of respondents indicating that they had basic knowledge and concepts, 70.8% indicating that they practiced healthy lifestyles and behaviors, and 33.5% showed proficiencies in terms of health skills. From high to low, the health literacy levels for the six types of health problems were safety and first aid literacy (80.5%), scientific outlook on health (76.4%), infectious disease prevention and control literacy (60.2%), chronic disease prevention and control literacy (70.9%), basic medical literacy (52.7%), and health information literacy (50.2%). The results of a multivariate logistic regression analysis showed that physical condition, a lifestyle harmful to one′s health, highest educational background, and a professional title in the previous year were the independent influencing factors related to health literacy ( P<0.05). Conclusion:Levels of health skills, basic medical literacy, and health information literacy among medical staff are low, and physical condition in the previous year, lifestyle, professional title, and education are important factors influencing the level of health literacy among medical staff.

Results All the indexes improved in both groups after treatment(|t|>3.194,P<0.01),and they were better in group A than in group B(|t|>2.122,P<0.05),except the score of ABC. Conclusion Combination of therapeutic listening is more effective on sensory processing and social interaction in ASD children.

ObjectiveTo explore the data standard system of electronic medical records in the field of rehabilitation, focusing on the terminology and coding standards, data structure, and key content categories of rehabilitation electronic medical records. MethodsBased on the Administrative Norms for the Application of Electronic Medical Records issued by the National Health Commission of China, the electronic medical record standard architecture issued by the International Organization for Standardization and Health Level Seven (HL7), the framework of the World Health Organization Family of International Classifications (WHO-FICs), Basic Architecture and Data Standards of Electronic Medical Records, Basic Data Set of Electronic Medical Records, and Specifications for Sharing Documents of Electronic Medical Records, the study constructed and organized the data structure, content, and data standards of rehabilitation electronic medical records. ResultsThe data structure of rehabilitation electronic medical records should strictly follow the structure of electronic medical records, including four levels (clinical document, document section, data set and data element) and four major content areas (basic information, diagnostic information, intervention information and cost information). Rehabilitation electronic medical records further integrated information related to rehabilitation needs and characteristics, emphasizing rehabilitation treatment, into clinical information. By fully applying the WHO-FICs reference classifications, rehabilitation electronic medical records could establish a standardized framework, diagnostic criteria, functional description tools, coding tools and terminology index tools for the coding, indexing, functional description, and analysis and interpretation of diseases and health problems. The study elaborated on the data structure and content categories of rehabilitation electronic medical records in four major categories, refined the granularity of reporting rehabilitation content in electronic medical records, and provided detailed data reporting guidance for rehabilitation electronic medical records. ConclusionThe standardization of rehabilitation electronic medical records is significant for improving the quality of rehabilitation medical services and promoting the rehabilitation process of patients. The development of rehabilitation electronic medical records must be based on the national and international standards. Under the general electronic medical records data structure and standards, a rehabilitation electronic medical records data system should be constructed which incorporates core data such as disease diagnosis, functional description and assessment, and rehabilitation interventions. The standardized rehabilitation electronic medical records scheme constructed in this study can support the improvement of standardization of rehabilitation electronic medical records data information.

ObjectiveTo analyze the data structure and standards of rehabilitation outpatient medical records, to provide data support for improving the quality of rehabilitation outpatient care and developing medical insurance payment policies. MethodsBased on the normative documents issued by the National Health Commission, Basic Standards for Medical Record Writing and Standards for Electronic Medical Record Sharing Documents, in accordance with the Quality Management Regulations for Outpatient (Emergency) Diagnosis and Treatment Information Pages (Trial), reference to the framework of the World Health Organization Family of International Classifications (WHO-FICs), the data framework and content of rehabilitation outpatient medical records were determined, and the data standards were discussed. ResultsThis study constructed a data framework for rehabilitation outpatient medical records, including four main components: patient basic information, visit process information, diagnosis and treatment information, and cost information. Three major reference classifications of WHO-FICs, International Classification of Diseases, International Classification of Functioning, Disability and Health, and International Classification of Health Interventions,were used to establish diagnostic standards and standardized terminology, as well as coding disease diagnosis, functional description, functional assessment, and rehabilitation interventions, to improve the quality of data reporting, and level of quality control in rehabilitation. ConclusionThe structuring and standardization of rehabilitation outpatient medical records are the foundation for sharing of rehabilitation data. The using of the three major classifications of WHO-FICs is valuable for the terminology and coding of disease diagnosis, functional description and assessment, and intervention in rehabilitation outpatient medical records, which is significant for sharing and interconnectivity of rehabilitation outpatient data, as well as for optimizing the quality and safety of rehabilitation medical services.
