Objective To learn current status of health management provided by primary health professionals working in rural areas of Beijing.Methods Health professionals in township hospitals in Beijing were selected by multi-phase random sample method in 2012 and surveyed by a standardized questionnaire to gathering the data on various health management contents,including health checkup,chronic disease management et al,the action location,its collaborative persons and sectors.Statistics description and inference were conducted to describe and compare the distribution of health management implementation across rural areas by descriptive methods and test,respectively.Results Nearly 66.3％ (321/484) of subjects provided health check-up,and 19.1％ (92/481)involved in follow-up study of mental diseases.The main targets population of health management were chronic diseases and the elderly,with response rate of 44.7％ (214/479) and 38.0％ (182/479),respectively.Health check-up,health education and follow-up of chronic diseases were performed in 62.1％ (298/480),52.4％ (251/479) and 42.8％ (206/481) of the township health centers.About 66.1％ (292/442) township health centers had cooperation with general practitioners; however,cooperation with administrative personnels was only 10.6％ (47/443).More than 41.4％ (201/463) township health centers cooperated with community administrative sectors,and cooperation with the propaganda department was only 10.6％ (49/464).The statistical difference across regions shows in the following,including health management action (health checkup,chronic disease patients following-up,et al),the target population covered (youth,elder person,children,and chronic disease patients),health management location(health checkup,education and chronic disease patients following-up in township hospital and village clinic),cooperation with General Practitioner.Conclusions Our results suggest that the actual situation on health management service in Beijing rural areas and the standards of public health equalization of China are still disjoined,even difference exists across regions.In order to improve the health management service quality,we should strengthen the health management personnel training,increase the general practitioner in proportion,establish the performance evaluation mechanism,increase governmental finance to support those service.

Objective To investigate the awareness and trainning needs of health management knowledge in primary healthcare professionals in Beijing.Methods Six hundred primary healthcare staff from Daxing,Fangshan,Miyun,Pinggu and Huairou District of Beijing were selected in 2012 through muhiphase random sampling method and required to complete a standardized questionnaire.The survey included the average awareness rates of health management(tobacco,body weight and alcohol consumption control and daily physical exercises),the rates of application and conception awareness of risk assessment tools of chronic diseases,the awareness rates of normal levels of blood pressure and serum glucose as well as training needs.Differences in different regions were analyzed.Chi-square test was used for data analysis.Results The average awareness rates of tobacco,body weight and alcohol consumption control and daily physical exercises were 94.1％ (513/545),95.3％ (522/548),94.0％ (515/548) and 85.9％ (470/547),respectively.However,the rates of application and conception awareness of risk assessment tools of chronic diseases were only 55.1％ (295/535) and 59.8％ (329/550),respectively.Those who knew the normal levels of blood pressure and serum glucose accounted for 85.4％ (475/556) and 92.4％ (514/556),respectively; although only 23.6％ (131/556) and 21.2％ (118/556) were completely familiar with the major risks of these conditions.About 57.4％ (308/537) or 56.7％ (305/538) participants reported urgent needs for health education on diabetes and hypertension management.Conclusion The awareness of health management of primary healthcare professionals in rural areas of Beijing remains lower and may need to be raised by education or training.

Objective To analyze the epidemic characteristics of volunteer blood donors with HIV infection in Suzhou city, in order to make countermeasures to recruit appropriate volunteer blood donors. Methods Infectious situation and population characteristics of volunteer blood donors with HIV infection were explored by a retrospective analysis method in Suzhou city between 2012 and 2013. Results Among 755 643 volunteer blood donors from 2002 to 2013, 51 donors were HIV infection, the positive rate was 6.75/100000, and the highest detection rate was found in 2013 (23.25/10万), following as 2012 for 9.71/100000, and the lowest was 1.66/100000. There was a statistically significant differ-ence among these years(χ2=37.96, P<0.01). 42 cases of 51 cases with HIV infection were men, the other 9 were women, sex ratio between male and female was nearly 5:1. The donors with 18 to 30 years old (60.79%) were predominant pop-ulation, unmarried people were as high as 62.75%, the staff were 56.86%, the donors with high school, technical sec-ondary school degrees and following degrees primarily accounted for 50.98%, and individual donors accounted for 70.59% of HIV infections. Conclusion There is an upward trend of HIV infection rate from voluntary blood donors in Suzhou in recent years. Blood collection organization should strengthen the health consultation of voluntary blood donors before the blood donation, especially among young adults, strict screening for HIV, which guarantee for clinical safety of blood transfusion.

Objective:To investigate the value of pulse oxygen saturation (SpO 2) monitoring in predicting children with moderate-to-severe obstructive sleep apnea (OSA). Methods:It was a retrospective study involving 341 children with snoring during nighttime sleep who had visited the Children′s Hospital of Soochow University from June 2017 to November 2020 and monitored for polysomnography (PSG) and SpO 2.The SpO 2 parameters mainly included oxygen desaturation index (ODI), oxygen desaturation index ≥3% (ODI3), oxygen desaturation index ≥4% (ODI4), mean pulse blood oxygen saturation (MSpO 2), lowest pulse blood oxygen saturation (LSpO 2), cumulative time spent with blood oxygen saturation below 95%, 92% and 90%(T95, T92 and T90). According to obstructive sleep apnea hypopnea index (OAHI), patients were divided into the snoring and mild OSA group (OAHI≤5 times/h) and moderate-to-severe OSA group (OAHI>5 times/h). Differences in SpO 2 parameters were compared between groups using the Chi- square test and Mann- Whitney U test. Spearman correlation analysis was used to analyze the correlation between SpO 2 parameters and OAHI in all children.The SpO 2 parameters were included in the Logistic regression model.Receiver operating characteristic (ROC) curve was used to analyze the diagnostic efficiency of SpO 2 parameters on moderate-to-severe OSA. Results:A total of 341 patients were recruited, including 206 male and 135 female patients with the mean age, body mass index (BMI) and OAHI of 6.0 (4.0, 7.5) years, 16.2 (15.1, 18.0) kg/m 2 and 0.6 (0.1, 3.0) times /h, respectively.There were 283(83.0%) and 58 (17.0%) patients in the snoring and mild OSA group and moderate-to-severe OSA group.The ODI3[0.7 (0.3, 1.4) times/h vs.7.7 (4.4, 12.8) times/h], ODI4[0.4 (0.1, 0.8) times/h vs.5.3 (2.7, 9.1) times/h], T95[1.4 (0.3, 5.3) min vs.13.7 (7.0, 33.5) min], T92[0.1 (0, 0.5) min vs.1.8 (0.9, 6.0) min] and T90[0 (0, 0.1) min vs.0.6 (0.2, 2.2) min] were significantly lower in the snoring and mild OSA group than those of moderate-to-severe group, while LSpO 2[91.0 (89.0, 93.0)% vs.86.5 (82.0, 88.0)%] and MSpO 2[ 97.0 (97.0, 98.0)% vs.96.0 (96.0, 97.0)%] were significantly higher(all P<0.001). All SpO 2 parameters were significantly correlated with OAHI (all P<0.001), and the correlation coefficient between ODI3 and OAHI was 0.660.ODI3 was an independent predictor of moderate-to-severe OSA ( OR=3.117, 95% CI: 1.635-5.945, P=0.001). The area under the ROC curve of ODI3 in predicting the moderate-to-severe OSA was 0.957, and the cut-off value of 3.45 times/h and specificity of 95.4%.MSpO 2 was an independent predictor of moderate-to-severe OSA ( OR=2.917, 95% CI: 1.589-5.354, P=0.001). Conclusions:ODI3 can be used to predict the moderate-to-severe OSA in children.

OBJECTIVES: Accurate breast lesion surface localization can guarantee accurate biopsy and local treatment. But there is no guideline to regular equipment and methods for the localization of breast lesions. The conventional non-invasive localization method is marker-based localization. The advantages of this method are simple and efficient. The disadvantages are that markers disappear easily under coupling agents; the positioning length of markers cannot last long on skin; and healthcare associated infection due to many patients using the same marker pen is potentially unavoidable. Breast lesion sticker (called sticker for short) is a new-type localization medical instrument in 2020. Our study aims to explore the clinical value of a new lesion stickers in breast lesion surface localization via comparison of the sticker and marker pen localization methods. METHODS: This was a prospective cohort study. It was conducted in 67 patients who needed breast lesion surface localization before biopsy. The patients were randomly assigned into 2 groups. One group of patients used marker pen to mark breast lesion surface location by ultrasonography. The other group of patients used stickers. Patients labeled with markers on skin were swabbed agents before marking. Then the markers were checked by ultrasound scan. If the surface positions of breast lesion were not correct, the above procedure was repeated. In the sticker group, the stickers were released synchronously after the lesions were detected by ultrasound scan. Then locations were checked via scanning hole. If the surface positions of breast lesion were not correct, the above procedure was repeated. The accuracy of positioning, the length of positioning time and satisfaction of patients between the 2 groups were compared. The length of positioning time was calculated from the time when ultrasound detected the lesion to the time when the surface position of breast lesion was confirmed. The total score of patients' satisfaction was 5 points according to Service Quality Evaluation of SERVQUAL Scale, including sonographers' service attitude and their technical proficiency, other medical staffs' service attitude and their technical proficiency, hospital service procedures, positioning comfort, and positioning effects. RESULTS: All 67 patients were females, aged 18-66 (39.73±13.10). There were 35 patients in the marker pen group and 32 patients in the sticker group. The time length of group used marker pen to localization was 22-88 (52.20±2.90) s, and the sticker group was 3-15 (9.22±0.58) s in length. The length of positioning time for the stickers was significantly shorter than that of the marker (P<0.01). Both methods were accurate in the surface localization of lesions before operation. The total scores of patients' satisfaction was 4-5 (4.92±0.02) in the stickers group, and 1-5 (3.35±0.10) in the marker pen group. The patients' satisfaction scores with the sticker were significantly higher than those with the marker pen (P<0.01). The length of positioning time and patients' satisfication scores for sonographer with 20 years' working experience were shorter and higher than those of sonographer with 10 years' working experience, respectively (both P<0.05). CONCLUSIONS The new breast lesion positioning stickers have more advantages than the marker pen in localization efficiency. It could reduce the workload of medical workers and increase patients' satisfaction to some extent. The stickers can be used not only in the breast lesions surface localization, but also in the skin location of pleural effusion and ascites, the skin location of surface masses, the skin location of thyroid nodule, and many other clinical marker areas, to further expand the scope of clinical application and value of the stickers.

Idiopathic pulmonary fibrosis (IPF) is a progressive lung disease with unclear etiology and limited treatment options. The median survival time for IPF patients is approximately 2-3 years and there is no effective intervention to treat IPF other than lung transplantation. As important components of lung tissue, endothelial cells (ECs) are associated with pulmonary diseases. However, the role of endothelial dysfunction in pulmonary fibrosis (PF) is incompletely understood. Sphingosine-1-phosphate receptor 1 (S1PR1) is a G protein-coupled receptor highly expressed in lung ECs. Its expression is markedly reduced in patients with IPF. Herein, we generated an endothelial-conditional S1pr1 knockout mouse model which exhibited inflammation and fibrosis with or without bleomycin (BLM) challenge. Selective activation of S1PR1 with an S1PR1 agonist, IMMH002, exerted a potent therapeutic effect in mice with bleomycin-induced fibrosis by protecting the integrity of the endothelial barrier. These results suggest that S1PR1 might be a promising drug target for IPF therapy.
