Description of the practice, significance and principles of networking operation for primary medical institutions in Shenzhen, and an introduction to the strategy and implementation assurance. The paper covered the following features of such operation: establishment and upgrading of the primary patients movement system; establishment of the tiered health service system; establishment of the consultation and referral system based on networking operation; establishment of multi-institution practice system for physicians within the network; establishment of medical resources sharing system within the network; support for joint research programs; experiment in effective medical insurance payment and health service price support system; diversity and loose structure of institutions within the network

By analyzing the present development and reform experiments for public hospitals in Shenzhen,the author proposed the following directions for such a reform:1) Accelerating steps of the development strategy "One Large and One Small",to achieve a balanced deployment of local healthcare resources;2) Building a public hospitals group with reasonable resources deployment and information resources sharing;3) Advancing reforms of public hospitals,building an administrative system of public hospitals featuring separation between government functions and hospitals operations and that between hospital administration and hospital building;4) Improving the supervision mechanism for public hospitals featuring distinct rights and responsibilities and powerful regulatory practice;5) Building a scientific operation system of efficient incentives and self constraints;6) Building a service model for public hospitals featuring separation of medical service and pharmaceuticals sales and normalized system.

OBJECTIVETo investigate effects of systemic red light therapy on wound repair of burned patients and discuss its possible mechanisms of wound healing promotion.

METHODS138 burned patients were randomly divided into systemic red light treatment group (n = 69) and control group (n = 69). Patients in control group received routine therapy, while those in test group were given systemic red light therapy once a day, 30 minutes at a time until the wounds were recovered. The clinical findings and variables indicating wound repair were assessed on the 7th, 10th, 14th day, 21st day post-burn and the day when the wounds were healed.

RESULTSMean time of wound recovery were 19.86 +/- 2.43 days and 21.02 +/- 2.97 days respectively of those deep-thickness wounds in test group and control group, with statistically significance (P < 0.05). For the severity of the pain, VAS during time of dressing change on the 10th, 14th day post burn was lower in test group than that in control group which indicated less painful in test group (P < 0.05), suggesting pain relief effect of systemic red light therapy.

CONCLUSIONSystemic red light therapy was effective to promote wound healing of deep-thickness burn wounds and other similar acute wounds. Simultaneously, it is efficacious in pain relief and safe for those patients.

Objective To evaluate the performance characteristics of the second trimester double-marker test for the detection of fetal Down's syndrome in mainland China. Methods This prospective national multi-centered study used alpha-fetoprotein (AFP) and free β-subunit of human chorionic gonadotrophin( free β-hCG)as the serum markers. From May 2004 to September 2006, 11 centers participated in the collection and analysis of maternal serum AFP and free β-hCG between 14 and 20+6 weeks of pregnancy. The screening results were calculated using the standard algorithm based on the standard database provided with the analytic software. Patients with an increased risk of Down's syndrome pregnancy (≥1/270) were offered genetic anmiocentesis. Outcomes of all pregnancies were obtained.Results A total of 66 132 singleton pregnancies were included in the study. The median maternal age was 27 years. At a cut-eft of 1 in 270, the detection rate (DR) based on a Caucasian database was 72% corresponding to a false positive rate (FPR) of 5%, and the DR based on the Chinese database was raised to 76% corresponding to an FPR of 5%. Conclusion The double-marker test using AFP and free β-hCG is an effective screen strategy for second-trimester detection of fetal Down's syndrome in mainland China. Ethnic variance exists between the Caucasian and Chinese populations. The accuracy of screening is increased by the use of race-specific medians.

Objective:To collect data on urinary flow rate in the elderly female population across the country and to analyze the range of reference values.Methods:This study enrolled 333 subjects from July 2020 to June 2022.The study implementation process was divided into two steps.In the first step, subjects completed an electronic questionnaire, which included basic information about the subject, a short form for urinary incontinence, and a scoring form for the symptoms of overactive bladder syndrome.In the second step, the staff introduced the use of a mobile uroflowmetric device and distributed the instrument and materials.Uroflow rate data were automatically uploaded to a cloud database via the mobile phone.Subsequently, two or more physicians specializing in urinary control performed Uroflow rate-qualifying screenings and conducted statistical analyses.Results:A total of 333 subjects were enrolled in the study, and the researchers collected 1375 qualified urine flow rate records using a mobile urine flow rate instrument.The age of the subjects ranged from 60 to 84 years, with a mean age of 69 years.The reference ranges for urinary flow rate were found to be 24.8-26.2 s, with a mean urinary flow rate of 12.2-12.9 ml/s, a maximum urinary flow rate of 22.2-23.4 ml/s, and a time to peak of 8.5-9.7 s. The study observed a tendency for both maximal and mean urinary flow rates to decrease in older women as their age increased(Pearson correlation coefficient: -0.1, P<0.001). Conclusions:The uroflow rate of older women decreases with aging.Specifically, the average uroflow rate of women over 80 years old is lower than that of other age groups.This study aims to establish normal uroflow parameters for uroflowmetry in healthy older women in China.
