METHODS:Questionnaire was designed to investigate the drug manufacturers’attitude and suggestions to the national assessment programs of sampling and testing policy;SPSS 18.0 software was adopted to analyze the data;a reliability analysis was conducted for the 17 variables in the table;and a principal component analysis was conducted for the topics with strong correlation. RE-SULTS:A total of 340 questionnaires were sent out,314 were effectively received with the effective rate of 92%. the total internal consistency reliability coefficient Alpha was 0.92;the awareness coefficient of enterprise on the evaluation of sampling and testing was 9.78;4.24 enterprises were relatively agree the evaluation of sampling and testing;the attitude coefficient of enterprise on the improvement of evaluation of sampling and testing was 13.39;and the average score of enterprise on the overall satisfaction scoring was 8.73. CONCLUSIONS:The drug enterprises show high overall recognition for the national assessment programs of sampling and testing policy,and willing to cooperate with the development,and hoping the policy can be improved.

Objective To establish a HPLC method for the determination of preservative in iron maltose syrup.Methods A Kromasil 100-5 C18 column was used with acetonitrile-sodium acetate buffer solution(40 ︰60) as the mobile phase at the flow rate of 1.0 mL/min and 254 nm as the detection wavelength.The column temperature was set at 30 ℃.Results The calibration curve was linear within the range of 0.62 ~3.72 μg/mL for methyl parahydroxybenzoate, 0.18~1.07μg/mL for propyl parahydroxybenzoate, and the linear equation was Y=228494X-2512.5,Y=203351X-3471.4, respectively.The average recovery of methyl parahydroxybenzoate, propyl parahydroxybenzoate was 100.9%(RSD=1.5%),99.6%(RSD=0.5%), respectively.Conclusion The established method is simple, rapid and accurate, which could be used in the determination of preservative in iron maltose syrup.

The effects of Traditional Chinese medicine (TCM) nursing operation in cervical spondylitis have been generally recognized. This paper reviewed the applications and improvements of the major three TCM nursing operations, cupping, Gua-Sha and acupressure. The future developments in moxibustion, auricular point sticking, fumigation and washing therapy and moisten compress therapy were also prospected.

AIM: To evaluate the effects of total flavonoid of chrysanthemum on the expressions of Fas and FasL in male rabbits with dry eye, and to investigate the therapeutic effects of the total flavonoid of chrysanthemum on dry eye.
METHODS: Totally 150 male Japanses white rabbits were divided into blank group ( group A ) , sham -operated group ( group B ) , model group ( group C ) , androgen control treatment group (group D), and total flavonoid of chrysanthemum treatment group ( group E ) . The dry eye model was established with orchiectomy on group C, D and E. Rabbits in group E were treated with total flavonoid of chrysanthemum. Rabbits in group D were treated with androgen intramuscular injection. Rabbits in the group A, group B, group C was treated with normal saline. All rabbits were detected with Schirmer's Ⅰ test and tear break-up time (BUT). Fas, FasL were checked on immunohistochemistry.
RESULTS:The Schirmer's I test values of group E was significantly higher than that of group C ( P<0. 01 ) and the BUT value of group E was significantly longer than that of group C ( P<0. 01 ). The quantity of positive expression of Fas in glandular tube cell and acinar epithelial celland apoptosis cells of group E after treatment at 1, 3, 5mo were significantly lower than that of group C, cell population of the positive expression of FasL was obviously higher than that of group C (P<0. 01).
CONCLUSION:The main component of chrysanthemum is flavonoid, which could significantly inhibit happening of dry eye in rabbit after androgen level lowered and lacrimal gland apoptosis and keep basic tears secretory volume and tear film stability.

Objective To establish the preferable puberty pathological aggression animal model.Methods The experimental models were established towards puberty rats by frustration test of non-reward and instigation test.Rat models were tested for specificity using open-field test,saccharine test,elevated plus-maze(EPM)and olfactory sensibility.Results ①Compared with normal aggression(52.5±5.36)and control group(8.83±1.34)in total aggressive times,the pathological aggression group(101.17±2.85)increased significantly(P<0.01);②Some behavior items of each model group were moderately or hishly correlated to total score(r=0.379～0.929);③There was a significant difference between pathological aggression group and normal aggression group in the numbers of attack toward vulnerable-body regions,persistence attack after intruder displayed submissive and hish attack/threat ratios(P<0.01);④The pathological aggression group did not show depression,anxiety and olfactory disorder,except for space cognitive function(P>0.05).However,the normal aggression group displayed obvious depressive mood.Conclusion Each behavioral index matches the criteria of pathological aggression model.Meanwhile,it also excludes other factors of disturbing the specificity of the model.It suggests this model may be preferable puberty pathological aggression animal model.

A piece of news was introduced into pharmacology course examination.Students were asked to make comments on the news based on pharmacology knowledge or principles.All points of view were summarized and given back to the students after the examination. The right way to answer the question was discussed and a consensus on the answer was reached.lt was indicated that the teaching method in the trial is helpful for improvement of students' overall analytical skills.

Objective To investigate the contribution of Cystatin C to the preoperative diagnosis and clinical therapy of gastroenteric tumor.Methods Using surgical materials from patients with stomach, colon and rectum cancer, immunohistochemisty, sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) and Western blotting analysis were performed with antibodies against Cystatin C.Cystatin C of the cancerous and paired noncancerous lesions were determined by enzyme-linked immunosorbent assay (ELISA).Results (1)Immunohistochemical staining of Cystatin C was evident expression in cancer cells and associated stromal tissues, this was not the case in paired noncancerous tissues,there were also statistical relationship between the expression of Cystatin C in cancerous and that in noncancerous tissues (?~2=6.825,P

The purpose of this study is to assess the nutritional value and biological effect of Collybia Velutipes. The results were as follows: (1) 10% Collybia Velutipes extract contains 19210mg/L of total amino acid. It is more than the content in the equal amount of mushrooms. (2) The kindergarten children were fed with Collybia Velutipes product for 7 weeks. It was found that the height and the circumference of the mid-upper arm in the children were significantly higher than the control. (3) Weanling male and female rats of wistar strain were divided into two groups ana led the following diets: group l(control), Collybia Velutipes (CV) free diet; group 2(subject), diet containing 25% CV product which contains 2.5% dried CV. The rats were fed the diet ad libitum for 6 weeks. At the end of the experiment, we found that the food effect (FE) of the subject group was significantly higher than the control (P

Chronic cerebral circulation insufficiency (CCCI) was preferred as a new disease name in recent years. It can cause ischemic and different degrees patho-damage in brain tissue. Accordingly, it lead to decrease the function in perception and cause aphronesia. It had attracted great attention for native and foreign researchers. In this article, the authors will summarize recent research province on empirical research, clinic auxiliary diagnosis and treatment status in the CCCI.

Toll like receptors (TLRs) are the earliest discovered natural immune pattern recognition receptors (PRRs). The abnormality of TLR signal transduction pathway is the key factor leading to chronic inflammatory, cancer, nervous system disease and cardiovascular diseases. The development of TLR agonists and inhibitors has attracted much attention. Currently known TLR2 agonists, such as lipopeptides or their derivatives, have certain limitations in drug development due to their difficult synthesis, easy hydrolysis, and triggering inflammatory cytokine storms, while inhibitors have been rarely reported. New small molecule TLR2 agonists or inhibitors with higher stability are more likely to be developed as tumor immunotherapy or anti-inflammatory drugs.
