In order to investigate the effects of aconitine on [Ca2+] oscillation patterns in cultured myocytes of neonatal rats, fluorescent Ca2+ indicator Fluo-4 NW and laser scanning confocal microscope (LSCM) were used to detect the real-time changes of [Ca2+] oscillation patterns in the cultured myocytes before and after aconitine (1.0 micromol/L) incubation or antiarrhythmic peptide (AAP) and aconitine co-incubation. The results showed under control conditions, [Ca2+] oscillations were irregular but relatively stable, occasionally accompanied by small calcium sparks. After incubation of the cultures with aconitine, high frequency [Ca2+] oscillations emerged in both nuclear and cytoplasmic regions, whereas typical calcium sparks disappeared and the average [Ca2+] in the cytoplasm of the cardiomyocyte did not change significantly. In AAP-treated cultures, intracellular [Ca2+] oscillation also changed, with periodic frequency, increased amplitudes and prolonged duration of calcium sparks. These patterns were not altered significantly by subsequent aconitine incubation. The basal value of [Ca2+] in nuclear region was higher than that in the cytoplasmic region. In the presence or absence of drugs, the [Ca2+] oscillated synchronously in both the nuclear and cytoplasmic regions of the same cardiomyocyte. It was concluded that although oscillating strenuously at high frequency, the average [Ca2+] in the cytoplasm of cardiomyocyte did not change significantly after aconitine incubation, compared to the controls. The observations indicate that aconitine induces the changes in [Ca2+] oscillation frequency other than the Ca2+ overload.

Objective Analyzing the regional distribution discrepancy of medical and health resources in China,with the purpose of providing the government with policy making evidences for optimizing medical and health resource allocation.Results Dividing China into three regions based on regional economic development and geographic setting,and selecting 6 indicators for medical and health resources.On the basis of the statistics of 31 provinces released by the state in 2009,analyzing the interprovincial disparities of the distribution of these six resources,by means of the coefficient of variation,Gini coefficient and Theil index.Methods The largest inter-regional allocation disparity is found in the number of biopharmaceutical manufacturing companies per ten thousand population.And the smallest discrepancy is found in the number of hospital beds among these regions.The top two extreme differences of resource possession per ten thousand population between the maximum and the minmum region are the number of biopharmaceutical manufacturing companies and tertiary hospitals.The eastern region is the largest contributor to the discrepancy of allocation for the six resources within and between regions.The less developed regions contribute the most inter-regional discrepancy for the allocation of medical practitioners(their assistants included),hospital beds,tertiary hospitals and pharmaceutical companies.And the developed regions contribute the most inter-regional discrepancy of medical finance support from local governments and the most of the allocation of biopharmaceutical manufacturing companies.In general,regions of higher development enjoy greater possession of the SIX resources per population in such regions. But these two are not always in direct proportion. Condnsion Regional distribution disparity of the six resources is not yetreasonable in China.To better meet the health needs of the population in various regions,the government is expected to increase its financial support for building biopharmaceutical manufacturing companies and tertiary hospitals in the less developed western regions,to better use resources of developed regions,and to keep off investments at low level and repetition.The government is also recommended to pay attention to the proportion of government health finance output and the quality and quantity of medical practitioners.

Objective To evaluate the effects ofYiqi Yangyin Huoxue Formula on clinical endpoints of diabetic nephropathy patients.Methods Totally 95 patients who were involved into the six-month DN clinical RCT for observation in 2008 were retrospectively collected and screened. There are 47 cases in the trial group, who were chronically treated by integrated traditional Chinese and Western medicine therapy which mainly adoptingYiqi Yangyin Huoxue Formula. There were 48 cases in the control group, who were chronically treated with Western medicine. Follow-up visits were conducted in 2011, 2012, 2013, and 2014 respectively. Long-term incidence rate of renal function progress/deaths were compared in the two groups.Results Five cases died in the trial group, among which one case died of renal failure. Eight cases died in the control group, among which five died of renal failure and multiple organ failure. The incidence of endpoints entering end-stage renal disease and renal function progress was much lower than that of control group. Conclusion Integrated traditional Chinese and Western medicine therapy dominated byYiqi Yangyin Huoxue Formula has good clinical efficacy of kidney protection, and can slow the progress of DN patients entering end-stage renal disease, and better than single Western medicine intervention.

Objective:To systematically evaluate the influence of the implementation of essential drug policy ( EDP) on prescrip-tion use rate of antibiotics in primary hospitals. Methods:Based on CNKI, Wanfang and VIP of China journal databases, all litera-tures were adopted including the data of the prescription use rate of antibiotics in primary hospitals. RevMan5. 3 and Stata 12. 0 soft-ware were used to conduct the Meta analysis. Results:Totally 43 literatures were included in the study according to the evaluation se-lection criteria. After the implementation of EDP, the prescription use rate of antibiotics in primary hospitals was decreased, and com-pared with that before the implementation of EDP, the risk difference value was significant [RD= -0. 03,95%CI( -0. 04,-0. 03), P<0. 000 01], while the use rate was still high (46. 16%). The result of Egger’s test indicated the publication bias of the 43 litera-tures was not significant (P=0. 571). However, there was high heterogeneity(I2 =94%,P<0. 000 01)among the different studies. Based on the classification of hospital type and different areas, the results of sub-group analysis showed the differences of study methods in the literatures and regional implementation measures of EDP contributed to the high heterogeneity among the different studies. Con-clusion:In order to reduce the heterogeneity of studies, a unified evaluation criteria for the research quality of the cross-section survey should be established. And special policies related to EDP should be taken to effectively decrease the use rate of antibiotics in primary hospitals.
