CONCLUSION: Computer management in combination with the modified ABC analytical method together with FQS and FIS management led to an effective and accurate inventory management of expensive drugs,which then resulted in a speedy turnover rate,decreased fund occupying and lowered drug cost.

Objective To study the effects of Tan Ⅱ A on the expression of c-Met and HIF-lα in gastric cancer SGC7901 cells under hypoxia and the correlation between c-Met and HIF-lα expression. Methods The model of hypoxia was established by CoCl2. There were three groups; normal control group, hypoxia control group, and hypoxia combined with different concentrations of Tan ⅡA group. After Tan ⅡA was added to the media with 0.5, 2.0 and 10.0 mg/L respectively for 48 h under hypoxia, the expression of HIF-1α and c-Met protein was detected by immunocytochemical staining. Results Immunocytochemical staining revealed that the expression of HIF-1α and c-Met protein was inhibited by Tan ⅡA in a dose-dependent manner under hypoxia. High positive correlation was found between the expression of HIF-1α and c-Met (n = 4, r = 0. 996, P <0.01). Conclusion Tan ⅡA might inhibit the expression of c-Met protein via down-regulation of HIFlα protein expression under hypoxia, suggesting that Tan ⅡA might play an important role in fighting against hypoxia-stimulated invasion and metastasis of tumor.

Objective To investigate the value of detecting HEART score and HEARTS3 score in risk stratification and prognosis of acute coronary syndrome (ACS) in patients with non-ST segment elevation chest pain in emergency department (ED).Methods Clinical data of case-control retrospective study of 775 patients with non-ST segment elevation chest pain in ED were collected from July 2011 to March 2015.The patients were estimated and risk stratification was made with HEART score and HEARTS3 score.After follow-up visiting by telephone for 30 days,outcomes were found to be ACS and myocardial infarction (MI).And the patients were categorized with score into low,intermediate and high risk groups.The correlation between the ACS and risk score in three groups was analyzed.Comparison of capability of performance in predicting 30-day ACS between the HEART score and HEARTS3 risk score.Statistical analyses were performed using SPSS13.0.Enumeration variables were expressed as percentage.For comparison of predictive value of the two sets of scores,area under the receiver operating curve (auROC) was calculated and compared by Z test.Results There were 92 cases with 30-day ACS.The rate of ACS had a trend of increase with increase in HEART score and HEARTS3 score.The patients with higher scores of HEART and HEARTS3,higher incidence of ACS in 30 days.Especially,the high-risk patients with score≥7 of HEART score and≥8 of HEARTS3 score had higher rate of ACS.And there was significant difference in predicting high-risk patients between two sets of scoring (P ＜ 0.05).The HEARTS3 score outperformed the HEART score as determined by comparison of areas under the ROC curve for MI (0.952 vs 0.813;P =0.028),30-day ACS (0.913 vs.0.815;P =0.034).Conclusions HEART score and HEARTS3 score both can be used to evaluate and perform risk stratification for non-ST segment elevation chest pain patients in ED.But HEARTS3 score can more precisely stratify high-risk patients with chest pain for 30-day ACS.

In order to reveal genetic diversity of domestic Andrographis paniculata and its impact on quality, genetic backgrounds of 103 samples from 7 provinces in China were analyzed using SRAP marker and SNP marker. Genetic structures of the A. paniculata populations were estimated with Powermarker V 3.25 and Mega 6.0 software, and polymorphic SNPs were identified with CodonCode Aligner software. The results showed that the genetic distances of domestic A. paniculata germplasm ranged from 0. 01 to 0.09, and no polymorphic SNPs were discovered in coding sequence fragments of ent-copalyl diphosphate synthase. A. paniculata germplasm from various regions in China had poor genetic diversity. This phenomenon was closely related to strict self-fertilization and earlier introduction from the same origin. Therefore, genetic background had little impact on variable qualities of A. paniculata in domestic market. Mutation breeding, polyploid breeding and molecular breeding were proposed as promising strategies in germplasm innovation.

OBJECTIVETo investigate the effect of castration on the quantity of androgen receptor (AR) and the epidermal growth factor (EGF) in the submaxillary salivary glands of castrated rats.

METHODSSixty male Wistar rats, aged 30 to approximately 60 days, were randomly divided into three groups of 20 rats: castrated, sham-operated and normal control (unoperated). The submaxillary salivary glands of the castrated rats were removed one week after surgery, and so were those of the rats in the sham-operated and the normal control groups. The homogenized salivary gland was used for Western-blots.

RESULTSThe quantity of AR and EGF in the submaxillary salivary glands was decreased significantly in the castrated rats compared with that in the sham-operated and the normal control ( P < 0. 05). Moreover, EGF secreted by the submaxillary salivary glands was also decreased in the castrated rats (P < 0.05).

CONCLUSIONCastration affected the production of androgen receptor in the salivary gland, and also, could further affect the secretion of EGF from the salivary gland.

This study left flavonoids and alkaloids Chinese herbal monomer with common parent nucleus as cream base carriages drug respectively, cream base were prepared with stable span 60-tween 80 emulsification system. The near-infrared stability analysis technology was performed to quantitatively characterize the physical stability of cream. Base on the theory of gel network structure, theory of emulsification, theory of solubility parameter and theory of double layer, the influence mechanism of Chinese herbal monomer on physical stability of cream was discussed. The results showed that tetrahydropalmatine, matrine and naringenin had similar solubility parameter value with cream base material, creams prepared with those Chinese herbal monomer have higher Zeta potential value and stronger physical stability, and that those creams had similar microstructure information with cream base. However, a larger solubility parameter difference exists between baicalin, baicalein, berberine, palmatine and cream base material. Creams prepared with those Chinese herbal monomers had lower Zeta potential value and poorer physical stability, and that those creams had great different microstructure information with cream base.
