METHODS: A total of 10.680 prescriptions prescribed since the issuing of the Prescription Management Method on May 2007 were reviewed for an analysis of the irrational ones involving nonstandard writing and inappropriate drug use. RESULTS: 12.0% prescriptions were nonstandard in writing and 51.6% were irrational in drug use. CONCLUSION: The prescriptions in our hospital under study are somewhat irrational in prescription writing and drug use,which is worth the highest alert.

Background The clinical efficacy and safety of mouse nerve growth factor(NGF) for injection have been evaluated by Ⅰ,Ⅱ,Ⅲ stage of clinical trials.But as a clinical drug,its adverse effects for special population should been further studied.Objective This clinical trial was to observe and assess the safety and tolerability of mouse NGF for injection during the application in juvenile and elder patients with optic nerve damage.Methods A multicenter non-randomized controlled trial for the safety evaluation of mouse NGF injection solution was performed in 100 eye centers in China.This study protocol was approved by the Ethic Committee of each drug research center,and written informed consent was obtained from the subject,legal mandatary and guardian prior to this study.Total 2046 patients who met the included criteria of optical nerve damage were enrolled.The patients were divided into the juvenile group(90 cases,＜ 18 years),youth-middle-age group (1868 cases,1 8-75 years) and older group(88 cases,＞75 years).Mouse NGF(30 μg)was intranuscularly injected once per day for 21 days in all the patients.Systolic and diastolic blood pressure,heart rate,intraocular pressure (lOP),laboratory examinations of blood and urine,blood biochemical indexes were recorded before and after injection.All adverse events were evaluated after administration of drug.Results There were 189 (189/2046,9.23％)dropped out cases,including 184 lost cases after 3 weeks of treatment and 5 withdrew cases from adverse responses of drug,with a shedding rate ＜10％ in each group.Total 1857 individuals finished this trial.No significant differences were found in the IOP,heart rate and blood pressure between before and after admninistration of grug in the juvenile group,youth-middle-age group and older group (P＞0.05).The incidence rate of the adverse response in the juvenile group,youth-middle-age group and older group was 57.78％,68.18％,60.01％ respectively,and the primary local adverse events were pain(48.89％),redness and swelling(59.09％),duration(54.49％),without significant difference in the rate of local adverse events among the three groups(X2 =2.302,P =0.324).The abnormal rates of laboratory results of blood and urine were not significantly different among the three groups(all at P＞0.05).The percentage of impaired fasting glucose was 7.46％,23.73％and 7.79％ in the juvenile group,youth-middle-age group and older group,respectively,and the percentage in the older group was higher than that in the juvenile group and the youth-middle-age group (x2 =8.685,P =0.005 ;x2 =27.720,P =0.000).Conclusions Injection of mouse NGF is well tolerated in juvenile and elder patients over the age of 75 years.

Objective To investigate the appropriate setting up of normal reference ranges of lymphocyte subsets in some flow cytometry laboratories and to study the effects of different flow cytometers and various reagents by different manufacturers on the analysis of peripheral blood lymphocyte subsets. Methods Three FCM labs (named A, B and C) in Beijing region were selected representing 3 commonly used flow cytometers (Beckman Coulter Epics XL, Beckman Coulter Cytomics FC500, BD FACS Calibur). 50 samples from healthy donors were distributed to 3 labs and tested according to individual lab's standard operating procedure to verify whether the normal reference ranges of peripheral blood lymphocyte subsets established were appropriate. The application of internal quality control was also investigated. Commercial blood quality control reagents were given to the 3 FCM labs and tested within 20 working days paralleled with routine samples. In addition, 20 patients' samples were prepared using 4 different combinations of reagents ( a , b , c and d). The results from combination a, which used the Beckman Coulter reagents and instrument, were compared to the results from combination b, c and d, which used reagents from different manufacturers. Then the prepared samples were tested on Beckman Coulter Epics XL to evaluate the effects of different combinations of reagents on the results of peripheral blood lymphocyte subsets analyzed by the same instrument. Furthermore, 24 patients' samples prepared by same reagents from Beckman Coulter company were tested on both Beckman Coulter Epics XL and BD FACS Calibur respectively to assess the effects of different instruments on peripheral blood lymphocyte subsets. 20 patients' samples prepared by same reagents and instruments were analyzed by Beckman Coulter Epics XL analytic system and BD FACS Calibur analytic system respectively to assess the effects of the two analytic systems on the lymphocyte subsets. Results Over 10% of the results for NK and T4/T8 in lab A as well as T4 in labs B and C fell outside of their normal reference ranges. The probabilities exceeding corresponding normal reference ranges were 16% ( 9/50 ), 24% ( 12/50 ), 22% (11/50) and 12% ( 6/50 ), respectively. The results using internal blood quality control in 3 FCM labs within 20 working days were all within the reference ranges of the quality control provided by the kit. The biases from b and c reagent combinations were substantial compared with that of reagent a combination. Among the biases from b and c reagent combinations, the lowest probability of bias exceeding 10% was T8 of combination b, which had probability of 70% (14/20). The highest probabilities of hias exceeding 10% were T3 and T4 of b and c reagent combinations, which reached 100% (20/20) . Furthermore, the biases of T3, T8 and B of d reagent combination compared with that of reagent a combination were also substantial. The probabilities of bias exceeding 10% were 35% (7/20) ,85% (17/20) and 75% (15/20), respectively. Comparing the results of samples prepared and analyzed by reagents and instruments from different manufacturers to that of samples prepared and analyzed by the same company's reagents and instruments showed that there were great discrepancies in T3, T4 , T8 , B and NK. The probabilities of bias exceeding 10% were 71% ( 17/24), 80% (19/24) ,38% (9/24), 33% (8/24) and 92% (22/24), respectively. The biases of T8, NK and B were substantial when compared the results from Beckman Coulter Epics XL analytic systems and BD FACS Calibur analytic systems. The probabilities of bias exceeding 10% were 55% (11/20 ), 70% ( 14/20 ) and 55% (11/20), respectively. Conclusions FCM labs should set up their own normal reference range for peripheral blood lymphocyte subsets. The normal reference range should be verified periodically. It is important to apply internal blood quality control regularly and accumulate the quality control results. The reagents and instrument for preparing peripheral blood samples should be from the same manufacturers.

Objective: To explore the significance of Th17 in hepatocellular carcinoma, expecially with HBV infection.Methods:Cytometric bead array(CBA) was employed to detect 5 cytokines(IL-2,IL-4,IL-6,IFN-γ,IL-17A)from 39 tumor and non-tumor tissues of HCC and combined clinical data for comparative statistic analysis.Results:The expression of IL-2,IL-4,IFN-γin liver cancer tissue[(4.61±0.28),(3.37±0.58),(3.08±1.08)pg/ml,respectively] was significant lower than non-cancer tissue [(5.57±0.59),(3.77±0.70),(3.69±1.20)pg/ml,respectively].Otherwise,the expression of IL-6,IL-17A in cancer tissue [(280.09±254.68), (2.66±1.66) pg/ml, respectively] was higher than non-cancer [(6.58 ±1.92), (1.49 ±0.98) pg/ml, respectively].And,whatever cancer or non-cancer tissue,the expression of IL-17A in tissue[(3.45±1.86)pg/ml] with high HBV load (>1 000 U/ml) was significant higher than tissue with low HBV load[(1.97±1.16)pg/ml].Conclusion: IL-17A was highly expressed in HCC,and IL-2,IL-4,IFN-γmay inhibit its expression,and IL-6 may promote it.Hepatitis B virus infection may promote Th17 expression,thereby reducing patient′s prognosis.

Objective To compare the curative effect of perindopril and metoprolol in the treatment of diabetic patients with asymptomatic cardiac insufficiency.Methods According to the method of random numbers, 152 diabetic patients with asymptomatic cardiac insufficiency were divided into the observation group and control group,with 76 cases in each group.The observation group was given with perindopril treatment,while control group was given with metoprolol treatment.The cardiac function index,glycosylated hemoglobin,BNP levels,the incidence of cardiac insufficiency and the occurrence of adverse drug reactions before and after treatment were compared.Results There were no significant differences in LVEF,Tei index and E/A between two groups before treatment (all P >0.05 ).Compared with before treatment,the cardiac function indexes of the two groups were significantly improved after treatment(t=5.96,4.83,4.91,10.22,5.68,5.18,all P<0.05),but the observation group were improved more significantly(t=5.64,4.67,5.03,all P<0.05).Before and after treatment,there was no significant difference in the levels of glycosylated hemoglobin(all P>0.05),and the difference between the two groups was not statistically significant(all P>0.05).The BNP levels of the observation group before and after the treatment were (515.43 ± 58.85)pg/mL and (214.43 ±32.42)pg/mL respectively,of which the control group were (513.94 ±59.11)pg/mL and (263.32 ±43.31)pg/mL respectively,and after treatment,the BNP levels of the two groups were significantly decreased(t=23.45,17.68,all P<0.05),of which the observation group decreased more obvious(t=6.97,P<0.05).The cardiac insufficiency incidence of the observation group was 3.95%,which was significantly lower than 14.47% of the control group(χ2 =5.03,P<0.05).The incidence of adverse drug reactions had no obvious differ-ences in both groups(χ2 =0.08,P>0.05).Conclusion Using perindopril in treatment of diabetic patients with asymptomatic heart function can obviously improve cardiac function,reduce the incidence of BNP and cardiac insuffi-ciency.It has the clinical curative effect and high safety.

Objective To evaluate the effect of Rab23 on the proliferation of a squamous cell carcinoma cell line Sa3,and to investigate its mechanisms.Methods Cultured Sa3 cells were classified into four groups:normal control group transfected with green fluorescent protein (GFP),Rab23-overexpressing group transfected with a GFP-labelled Rab23-overexpressing plasmid,Rab23-silencing group transfected with a plasmid carrying a Rab23-targeting shRNA,empty vector group transfected with an empty vector.After additional culture for different durations,plate colony formation assay and flow cytometry were performed to evaluate the proliferative activity of Sa3 cells,and Western blot was conducted to detect the expression of Erl/phosphorylated-Erk in Sa3 cells.Statistical analysis was carried out by t test,one-way analysis of variance and Bonferroni's multiple comparison test.Results Stable Sa3 cell lines with overexpression or silencing of Rab23 were established by plasmid construction and lentivirus-mediated transfection.The plate colony formation assay showed that the colony formation rate was significantly lower in the Rab23-overexpressing group than in the normal control group (2.3％ ± 0.2％ vs.3.6％ ± 0.3％,P ＜ 0.05),but higher in the Rab23-silencing group than in the empty vector group (4.1％ ± 0.2％ vs.1.8％ ± 0.03％,P ＜ 0.01).Rab23 overexpression induced G1 phase arrest in Sa3 cells.The proliferation index was significantly decreased in the Rab23-overexpressing group compared with the normal control group (0.581 ± 0.035 vs.0.698 ± 0.018,P ＜ 0.05),but increased in the Rab23-silencing group compared with the empty vector group (0.567 ± 0.015 vs.0.444 ± 0.014,P ＜ 0.01).As Western blot showed,there were no significant changes in the expression of Erk in the Rab23-silencing or-overexpressing group compared with the normal control group,whereas the expression of p-Erk was attenuated in the Rab23-overexpressing group compared with the normal control group,but enhanced in the Rab23-silencing group compared with the empty vector group.Conclusions Rab23 could inhibit the proliferation of Sa3 cells,which may be associated with the Erk pathway.
