OBJECTIVE: To establish the HPLC method for the determination of chloramphenicol and dapsone in compound chloramphenicol cream. METHODS: The analytical column was Hypersil ODS and the mobile phase consisted of 0.1%sodium heptanesulfonate solution (a mixture of 0.1% sodium heptanesulfonate 500 mL and dimethylformamide 5 mL plus acetic acid glacial 0.5 mL)-acetonitrile (75∶25) at a flow rate of 1.0 mL?min-1. The detection wavelength was 272 nm and the sample size was 20 ?L. RESULTS: The linear ranges of chloramphenicol and dapsone were 25.59～153.54 ?g?mL-1 (r=0.999 9) and 12.57～75.42 ?g?mL-1 (r=0.999 9), respectively. The average recovery rates were 100.62% (RSD=0.92%) and 100.93% (RSD=1.22%), respectively. CONCLUSION: The method is simple and accurate and can be used for the quality control of compound chloramphenicol cream.

Objective To investigate the effects of all -trans retinoic acid (ATRA),acitretin and tazarotene on apoptosis and active caspase-3 of human melanoma cells A375 and to discuss the relevant significance.Methods The effects of retinoids on apoptosis and active caspase-3 of A375 cells were examined in vitro.Early apoptosis analysis by double staining with annexin V-FITC and PI,and active caspase 3 analysis by the staining of FITC conjugated monoclonal rabbit anti active caspase-3 antibody were measured by flow cytometer.Results ATRA and acitretin induced apoptosis of A375 cells (both P＜0.05),but tazarotene was not effective (P＞0.05).ATRA and acitretin elevated the cell population with detectable active caspase-3 (both P＜0.05),but tazarotene was not effective either (P＞0.05).Acitretin played a most prominent role among the retinoids. Early apoptosis ratio was significantly and positively correlated with active caspase-3 percentage in both ATRA and acitretin (P＜0.05).Conclusions Acitretin and ATRA induce apoptosis of A375 cells in which caspase is critical.Retinoids are prospectively applied as an assisting alternative for treating melanoma.

Objective:To evaluate the effect of clinical pharmacists in the continued therapy of stroke patients .Methods:Totally 146 cases were selected and randomly divided into the observation group and the control group according to the standard matching meth -od.The observation group was treated with the continued therapy .The control group was given one-month telephone follow-up after the discharge.The differences in the drug compliance (Morisky scale), systolic blood pressure (SBP), diastolic blood pressure (DBP), glycosylated hemoglobin (HbA1C), serum total cholesterol ( TC), low density lipoprotein ( LDL-C), health behaviors ( HPLPⅡscale) and relapse rate were compared between the two groups in the 3rd, 6th and 12th month after the discharge.Results:The differ-ences in the above indices were statistically significant between the two groups ( P <0.05) at the various time points , and those were more significant with time extending (P<0.01).The difference of the relapse rate in the 3rd, 6th and 12th month after the discharge between the two groups were significant .Conclusion: Clinical pharmacists can improve the drug compliance and health behaviors of stroke patients and reduce the relapse rate .It is worthy to be recommended in clinics .

Objective To investigate expressions of STAT3 and phosphorylated STAT3(p-STAT3)in cutaneous malignant melanoma(CMM)lesions, and to explore their significance. Methods The expressions of STAT3 and p-STAT3 were detected with an immunohistochemical method using polymer enzyme-labeled secondary antibodies in skin specimens from 22 CMM lesions and 23 pigmented nevus lesions. The effects of STAT3 and p-STAT3 expressions on lymph node metastasis of CMM were evaluated. Results The expression rate of STAT3 was significantly higher in CMM lesions than in pigmented nevus lesions (95.5% vs. 56.5%, χ2 = 9.23, P < 0.05), so was that of p-STAT3 (90.9% vs. 43.5%, χ2 =11.38, P < 0.05). STAT3 expression in CMM lesions had no obvious effects on lymph node metastasis of CMM (P > 0.05), while the elevated expression of p-STAT3 in CMM lesions was a predictive factor for lymph node metastasis in CMM (OR = 1.88, 95% CI: 1.05 - 3.38, P < 0.05). Conclusion Increased expression of STAT3 and p-STAT3 in CMM may play important roles in the pathogenesis of CMM, and elevated p-STAT3 expression may contribute to invasion and metastasis of CMM.

Objective To investigate the role of oxidized LDL and coronary endothelial dysfunction in the development and progress of coronary heart disease(CHD).Methods 29 patients with unstable angina(UA),25 patients with stable angina(SA) and 20 patients without coronary heart disease(control) were studied.Oxidized low-density lipoprotein(ox-LDL)、 Nitric oxide(NO),and circulating endothelial cells(CEC) were measured in both coronary sinus and peripheral blood during percutaneous coronary intervention(PCI).Results The level of NO in coronary sinus in patients with CHD was lower,while the level of ox-LDL and CEC was markedly higher than those in the control group.In CHD patients,the level of NO in coronary sinus blood was lower,while the level of ox-LDL and CEC was higher than that in peripheral blood.It was no siginificant difference between coronary sinus and peripheral blood was observed in the control group.Conclusion Oxidized LDL not only plays an important role in coronary endothelial dysfunction,but also contributes to the progress in the cornornary heart disease.It may be one of the pathophysiological basis of acute coronary incidents.

Objective To explore the relationship of the plasma ox-LDL level and endothelium flow mediated vasodilation(FMD)in acute coronary syndrome patients(ACS).Methods From March to October 2004,in the Department of Cardiology,the Fourth PLA Hospital,51 patients with ACS were divided into 2 groups:AMI group(22patients)and UAP group(29 patients).20 subjects with normal coronary angiograms served as the control group.Nitrir oxide(NO)and plasma ox-LDL was measured by spectrophotometer and Sandwich ELISE method,respectively.The brachial arterial hyperemia-induced flow mediated vasodilation(FMD)and sublingual nitroglycerin(NTG)mediated vasodilation were measured by high resolution ultrasound.Results (1)The FMD in ACS group was significantly decreased compared with the control group[(7.2?1.42)、(7.6?1.12)vs(15.46?1.2),P0.05).(2)The No in ACS group was sigificantly lower than that in control group;the NO in AMI group was even lower[(48.46?12.44)、(60.42?10.30)vs(94.72?12.34)?mol/L,P1,which meant ox-LDL was a risk factor;the OR of FMD was
