Objective: To observe the therapeutic effects of RFA combined with chemotherapy drug on hepatic VX: carcinoma in rabbits and to explore its mechanism.Methods: 40 rabbit models with VX: carcinoma were used for this study.they were divided into four groups at random.We watched the changes in serolog ALT,diameter of tumor and pathomorphology.And we also utilized terminal deoxynucleotidyl ransferase-mediated dUTP nick-end-labeling and immunohistochemistry to observe the apoptosis and proliferation.Results: ⑴The blood ALT significantly increased at the first day after treatment,then descended at the third day,and at the seventh day it descended to the level of pretreatment stage in group RFA combined with epirubicin.(2) The diameter of tumor showed significant difference between combined treatment and other groups.(3) Two weeks after treatment,the complete necrotic area slightly extended.it was clearly seen that the zone consisted of normal liver constitution,inflammation hyperemia zone and amorphous necrotic constitution by HE staining in combined treatment group.(4) The apoptosis index of the combined treatment group was bigger than that in other groups by TUNEL technology,but the PCNA index in the combined treatment group was lower than other groups.They all had significant difference.There was negative correlation between apoptosis index and PCNA index in the combined treatment group(r=-0.745,P

The progress of modality therapy has improved both survival rate and quality of life of retinoblastoma(RB) patients.However,some problems are still left and unsolved.Parts of the RB relapse after they are treated for the first time.Even more remarkable,the related individuals to the RB patients run a risk of RB.Gene diagnosis and treatment are emerging and appear to solve these problems.Some researches in developed countries and Hong Kong have successfully made progress in gene diagnosis of RB.However,the detection rate of Rb1 gene mutation is very low.Researches documented for many years that gene diagnosis for RB is extremely complex,so we should go further to achieve a goal of gene diagnosis.Gene diagnosis of RB is still an initiation in China.We should strengthen relevant study and spread this technique.

A portable instrument for arteriosclerosis assessment containing sensor module, acquisition board and embedded module was developed for home care in this paper. The sensor module consists of one ECG module and three pulse wave extraction modules, synchronously acquiring human ECG and pulse wave signal of carotid, radial, and dorsal, respectively. The acquisition board converts the sensor module's analog output signals into digital signals and transmits them to the embedded module. The embedded module realizes the functions including signal display, storage and the calculation and output of pulse wave velocity. The structure of the proposed portable instrument is simple, easy to use, and easy to expand. Small size, low cost, and low power consumption are also the advantages of this device. Experimental results demonstrated that the proposed portable instrument for arteriosclerosis assessment has high accuracy, good repeatability and can assess the degree of atherosclerosis appropriately.

Objective To summarize and analyse the clinical data of death cases in the department of emergency internal medicine. Methods The clinical data of patients presenting at the department of emergency internal medicine from January 2005 to July 2010 were analyzed retrospectively. Results Among 13 211 patients of department of emergency internal medicine, 145 died. More cases died in winter( 32.0% , 39/122 ).More than half of deaths occurred within 6 hours after admission( 54.5% ,79/145 ). The top six death causes were sudden death, pulmonary infection, cerebrovascular accident, advanced cancer, gastrointestinal bleeding,cardiovascular diseases and the occurrence rates were 18. 6%, 13.8%, 13.8%, 10.3%, 9. 7% and 9.0%respectively. Conclusion The first three death causes in department of emergency internal medicine were sudden death, cerebrovascular accident, pulmonary infection. Prevention of these diseases, cooperation between emergency department and other departments and special training on standardized treatment of critically ill patients should be enhanced.

The paper reports the evaluation of the feasibility of using internal standard method for the determination of nicotine recovery in microdialysis in vitro. This in vitro experiment included two conditions. Nicotine and codeine phosphate were dissolved in Ringer's solution. Nicotine, codeine phosphate and the mixture of them were perfused through the CMA30 linear probe separately to calculate the proportion of the recovery (or delivery) of nicotine to that of codeine phosphate. And then codeine was perfused through the probe which was immersed in nicotine solution with different concentrations to calculate the proportion, too. In another condition nicotine was dissolved in rat plasma. The rat plasma protein binding rate was determined by using retrodialysis and internal standard method in vitro. The results are as follows: the proportion of the recovery (or delivery) of nicotine to that of codeine phosphate was fairly stable. The delivery of codeine was independent of nicotine concentration in the external medium. Protein binding rate determined by retrodialysis was almost the same as that determined by internal standard method. It suggests that the internal standard method is an effective way in the determination of nicotine recovery and codeine phosphate can be used as the internal standard.

OBJECTIVE: To offer support for optimizing marketing strategy and increasing consumption in drug retailing.METHODS: Microsoft SQL Server 2005 database was established,the data mining method was subjected to a correlation analysis using association rules with the daily sales data in a retail drugstore in Jiangsu as an example.RESULTS & CONCLUSIONS: The data mining of drug retailing consists of 4 items: construction of drug sales data mart,data pretreatment,data mining,and analysis of mining results.The application of the data mining in retail drugstore can help analyze the purchase tendency of customers,find out potential customers and increase sales volume.

The "all-free health care" system is being implemented in Shenmu County in Shaanxi Province,whose ethical orientation is during the transitional process from "basic medical insurance" to "meeting residents′ actual healthcare demand".The "all-free health care" system safeguards human health rights,embodies the principle of giving priority to social benefits,and is in accordance with the principle of effectiveness.However,due to the lack of scientific management,the capital flows violate the principle of prevention in the system.

Objective To explore the methods for the evaluation of the uncertainty of the determination of hardness in water. Methods A certain water sample was analyzed for the hardness according to EDTA-Na2 volumetry ruled by the Sanitory Standard for Drinking Water(2001).The mathematical model of the determination of hardness in water was established based on JJF1059-1999. The variance composition of the relative uncertainty was analyzed. The procedure of the evaluation of every uncertainty component was described in detail. Results The hardness in the water sample was 137 mg/L calculated according to mathematical model established in this study. The relative uncertainty and the expand uncertainty of the detection of hardness in the water sample were 0.008, 3 mg/L respectively. The expression of the uncertainty in the determination of hardness was (137?3)mg/L. Conclusion This method presented referable value for the evaluation of the uncertainty of volumetry determination method of hardness in water.
