Objective:To explore the usage of system dynamics analyzing the influencing factors of total health expenditure(THE),forecast the trends of total health expenditure based on the method of System Dynamics and put forward relative countermeasures.Methods:According to the literature and expert consultation,the population,elderly,GDP,government health expenditures,drug costs and the number of health workers per thousand population were the important factors for THE.These factors were incorporated into system dynamics model for total health expenditure and conducted the simulation.Results:Based on the examination,the simulation results highly corresponded to historical data (2002-2014) and the official forecast (2015-2020),which showed that the model had good stability and reliability.The simulation results showed that steadily increasing total health expenditure would reach 7 457.12 billion yuan in 2025.Conclusion:The system dynamics approach had superior characteristics to other projection methods in terms of stability and reliability.In order to control the irrational growth of total health expenditure,it needed to increase the prevention investment,decrease the incidence of chronic diseases;sustainably improve the reform of public hospitals,implement the basic drug system;change the income-oriented performance appraisal to realize the labor value of medical staffs.

Compared to the mature monitoring and reporting system of ADRs in developed countries such as the USA and EU,medical institutions in China have played too much a role.Instead,local primary monitoring and reporting system of ADRs should expand their scope of monitoring and reporting,as drug makers,chain drugstores and retailers should develop an effective ADR monitor/report system as well.At present,such a primary system is plagued by insufficient budget and staff,imbalanced urban/rural layout and defective statements.Recommended measures include enhanced surveillance for drug makers,chain drugstores and retailers,for higher reporting ratio of ADRs at primary level; greater publicity and better monitoring and penalty mechanism; better platform for various organizations.

Objective: To establish a microbial limit test method for compound benzocaine gel.Methods: According to the general principles of Chinese Pharmacopoeia (2015 edition), method applicable experiments were performed respectively for the routine method, neutralization method and dilution & neutralization method.Using the recovery ratio of test bacteria as the index, the medium of dilution & neutralization method was adopted in the total aerobic microbial count and total combined yeasts and molds count, and the neutralization method was used for the control bacteria detection.The neutralizing agents were polysorbate 80 and lecithin.Results: The method of dilution & neutralization could eliminate the bacteriostasis of the drug, and the recovery ratio of each test bacteria was within the range of 0.5-2.0, which was in line with the requirements of Chinese Pharmacopoeia.Escherichia coli, Pseudomonas aeruginosa and Staphylococcus aureus could be detected out in the positive control bacterial test,and bacteria were not detected out in the negative test.Conclusion: The method can be used for the microbial limit test for compound benzocaine gel.

OBJECTIVE: To investigate the significance and relationship between the expression of FOXC1 and clinicopathological features, and to explore its correlation with E-cadherin. METHOD: Immunohistochemical SP method was used to detected the expression of FOXC1 in nasopharyngeal carcinoma tissues and nasopharyngitis tissues. RESULT: (1) Immunoreaction to FOXC1 was mainly located in nucleus of nasopharyngeal carcinoma cells. The positive expression rate of FOXC1 in nasopharyngeal carcinoma tissues was 85.3% (81/95), which was significantly higher than that in nasopharyngitis tissues (59.4%) (P < 0.05). (2) The expression of FOXC1 was not related to patients' age and gender, clinical stage of cancer and lymph node metastasis (P > 0.05). (3) There was a correlation between the expression of FOXC1 and down-regulated expression of E-cadherin in nasopharyngeal carcinoma tissues (P < 0.05). CONCLUSION FOXC1 may play an important role in generation and progression of nasopharyngeal carcinoma, there may be a correlation between the expression of FOXC1 and down-regulated expression of E-cadherin, also FOXC1 may play an important role in the process of EMT in nasopharyngeal carcinoma by regulating E-cadherin.

Objective To study the effect of Shaoyaozhitong Mixture on stageⅢ-Ⅳendometriosis, and explore its mechanism. Methods Ninty-five cases of stageⅢ-Ⅳ endometriosis were randomly divided into three groups. The traditional Chinese medicine (TCM) group (31 cases) was treated with Shaoyaozhitong Mixture, the GnRHa group (31 cases) was treated with Triptorelin Acetate for Injection, while the expectant group (33 cases) received no medications. The changes of CA125, TNF-α and VEGF levels, visual pain score and SF-36 score, total effective rate, pregnancy and recurrence were compared. Results There were significant increases in CA125, TNF-α and VEGF levels, visual analogue pain score and SF-36 score in all the three groups after treatment (P<0.05). The decline of CA125, TNF-αand VEGF levels and visual analogue pain score in TCM group and GnRHa group was significantly faster and greater than that of the expectant group (P<0.05). The total effective rates of TCM group was 83.9%(26/31), GnRHa group was 87.1%(27/31), and expectant group was 60.6%(20/33), TCM group and GnRHa group were superior to the expectant group, respectively (P<0.05). The pregnancy rate was higher and recurrence rate was lower in TCM group and GnRHa group than that of expectant group, but there was no statistical difference (P>0.05). Conclusion Shaoyaozhitong Mixture is effective in treating endometriosis by inhibiting the growth of ectopic endometrium.

Objective:To investigate the effect of 12(S)-HETE on the p27~(kip1) expression in mesangial cells and glomeruli.Methods:Mesangial cells were exposed to 12(S)-HETE.12(S)-HETE was infused to rats by osmotic mini-pump.Total protein content measurement for cell hypertrophy,RT-PCR for mRNA expression and Western blot for protein expression were performed respectively.Results:12(S)-HETE stimulation induced mesangial cell hypertrophy and p27~(kip1) protein expression,but not p27~(kip1) mRNA expression.Furthermore,p27~(kip1) mRNA and protein expression in the glomeruli were significantly increased by 12(S)-HETE stimulation using osmotic mini-pump.Conclusion:12(S)-HETE plays an important role in the pathogenesis of glomerular cell hypertrophy and senescence through upregulation of p27~(kip1) expression.

Objective To determine the main reproductive performance of six SPF mice and rats preserved in our laboratory, including C57BL/6, BALB/c, NIH, KM, ICR mice and SD rats.Methods Inbred mice mated with full sib and random mating.Meanwhile, closed colony animals were bred by cross circular mating.These indexes of reproductive performance were measured in the six kinds of animals during the first birth to the fourth birth, i.e.the average litter size (ALZ), average baby number reared ( ABN) and average weaning number ( AWN), and weaning rate ( WA) were calculated.Meanwhile, the initial mating age in days, initial bearing age in days, first gestation and intervals were measured.Results The ALZ of inbred mice were 6 to 7.The reproductive indexes were basically stable in the first 3 births, however, the various data were dramatically declined in the fourth birth ( P<0.05 ) .The WA of BALB/c mice were 98%to 99%, and that of C57BL/6 mice were 96%to 98%.The ALZ of closed colony animals were 12 to 15, and significantly increased in the second and third births compared with that of the first birth (P<0.05), then was significantly reduced ( P<0.05) .The WA maintained at 98%to 99%in the NIH, KM and ICR mice.In contrast, The WA of SD rats was slightly lower, reaching 95%to 97%.The initial mating age in days of mice was between 70 d to 80 d.The initial bearing age in days and first gestation of rats were less than that of inbred mice, the initial bearing age in days and first gestation of closed colony rats were 136.3 d and 27.7 d, respectively.The pregnancy interval of inbred mice was between 34 d to 40 d,the pregnancy interval of closed colony mice was between 25.5 d to 28.7 d, the pregnancy interval of rats was between 32.8 d to33.8 d.Conclusions The 6 mouse and rat strains have a higher reproductive performance, and the data obtained in this study provide a basis for commercialized production of mice and rats in southern areas of China, and for establishment of rodent experimental animal resource.
