1.The economic effects of rural residents' health in China: Empirical analysis based on endogeneity
Chinese Journal of Health Policy 2017;10(4):71-76
As a sort of human capital, health is a concrete manifestation of human productivity.At home and abroad, there are many empirical studies focusing on the economic effects of health that have been conducted, but the research methods have not paid enough attention to the endogeneity of health in those studies.This paper evaluates the effects of health on the income of rural residents in China with the micro panel data from China Health and Nutrition Survey.To get reliable results, the paper controls the endogenity of health by using simultaneous equation model and solves the parameters by using the three-stage least squares method.The study found that health has significantly positive effects on the income of rural residents in China, a conclusion which is in conformity with the economic effects of health.To improve the health of rural residents and fully implement the economic effects of health, the study recommends the government to put more efforts on promoting healthcare services, health-related education, and improving the living standards of rural residents in China.

Stone retropulsion during ureteroscopic lithotripsy is a common troublesome problem for most urologists. Stone retropulsion can result in increase in health care cost and increased operative time. With the popularisation of ureteros?copy, additional procedures to treat residual migrated fragments has drawn more and more attention and research. In recent years, many equipment, devices and techniques are designed to resolve this big puzzle. We reviewed the literatures to sum?mary the strategy for preventing stone retropulsion during ureteroscopic lithotripsy.

Dioscin, a typical saponin, is widely present in the family of Dioscoreaceae, Liliaceae, Caryophyllaceae and Rosaceae, especially in Dioscoreaceae, including Discorea nipponica Makino, Dioscorea zingiberensis C. H. Wright and Dioscorea panthaica Prain et Burkill. Traditional Chinese medicine reported that dioscin plays a role in expectorant, relaxing the muscles and stimulating the blood circulation, aiding digestion and diuresis. With the development of science and technology in recent years, some new extraction and separation techniques and methods have been applied to the study of dioscin, and more and more pharmacological effects were found. Modern pharmacology studies have confirmed that dioscin had some activities on desensitization, anti-inflammatory, lipid-lowering, anti-tumor, hepatoprotection and anti-viral. After oral administration, dioscin is metabolized to diosgenin, which is the true active ingredient and is an important raw material to synthesize steroid hormone drugs. Therefore, the studies on dioscin are valueable and promising. In this review, we make a summary on the researches of dioscin including the extraction technology, separation and prepara- tion, chemical synthesis, drug metabolism, determination and pharmacological researches.

Objective To investigate the protective effect and it's possible mechanism of Tanshinone ⅡA in radiation-induced pulmonary fibrosis.Methods Having the right hemithorax of female Wistar rats irradiated(30?Gy) in 10 fractions within 14 days by 6 ?MV photons,the radiation-induced pulmonary fibrosis animal model was established.In the treatment group,sodium Tanshinone ⅡA sulfonate(15?mg/kg) was given by intraperitoneal injection 1 hour before each fraction of irradiation.Five months after irradiation,the difference of the histopathological changes,the hydroxyproline content and expression of TGF-?1 between the radiation alone group,tanshinone plus radiation and control group were analyzed by HE stain,Massion stain,immunohistochemical methor and reverse transcriptase polymerase chain reaction(RT-PCR) method.Results The histopathological comparison revealed the protective effect of Tanshinone ⅡA.The content of hydroxyproline was(21.99?3.96),((38.25?)(7.18)),(28.94?4.29)??g/g in the control group,radiation alone group and radiation plus Tanshinone ⅡA.The expression of TGF-?1(mRNA and protein) was reduced by Tanshinone ⅡA.Pathological changes of the pulmonary fibrosis was reduced by Tanshinone ⅡA yet.Conclusions Our study shows that Tanshinone ⅡA can inhibit radiation-induced pulmonary fibrosis,and the possible mechanism of its may be made possible through down-regulating the expression of TGF-?1 in the irritated lung tissue.
7.The discussion of the methods on troubleshooting of networking malfunction for mindray iPM-9800 central monitoring system
China Medical Equipment 2016;13(6):113-114,115
Objective:Common troubleshooting methods of networking malfunction for central monitoring system were discussed in order to realize its safe application of networking central monitoring system.Methods: Time calibration server and necessary conditions of network for central monitoring system were discussed and analyzed. In addition, practical troubleshooting and maintenance methods were proposed to solve the networking malfunction between a bedside monitor of Mindray iPM-9800 and its central workstation.Results: Smooth operation of networking central monitoring system could simultaneously obtain physiological parameters of several patients, thus largely improving the efficiency of medical staffs.Conclusion: Safe operation of networking central monitoring system could ensure the accuracy of real-time monitoring information of patients and improve hospital’s management level of network and informatization.

Objective:To probe the effect of prenatal ethanol exposure on the mitochondrial protein expression in fetal mouse cerebrum. Methods:Pregnant CD-1 mice were given 5.0 g/kg ethanol intragastrically from pregnant days (PD) 6-15. Fetal cerebral mitochondria were isolated on PD 18. The overall mitochondrial protein was applied to two-dimensional gel electrophoresis. Differentially expressed protein spots were cut off and identified by matrix-assisted laser desorption ionization time-of-flight (MALDI-TOF) mass spectrometry. Activities of respiratory chain complex Ⅳ(72.3%?4.6% of control)and ATP synthase, and ATP content in the fetal cerebral cells were measured. Results:Expressions of some constructional and functional proteins were altered by in utero ethanol exposure. Activities of respiratory chain complex Ⅳ and ATP synthase (80.3%?5.1% of control)were both decreased. ATP content (67.9%?3.9% of control) in the cerebral cells was reduced in the in utero ethanol exposure fetuses. Conclusion:In utero ethanol exposure affects the mitochondrial protein expression of fetal mouse cerebrum, even in the tissue without obvious morphological malformations, which may be a possible mechanism of behavioral defects found in children with prenatal ethanol exposure.
