OBJECTIVE:To improve the monitoring capability and reporting rate of the adverse drug reactions (ADR) in Shanghai Pudong new area. METHODS: By a retrospective study,a total of 1 906 ADR reports collected from 2006 to 2008 in Shanghai Pudong new area were analyzed statistically. RESULTS: The ADR were more often induced by Chinese patent medicines and antibiotics and in which different organs or systems were involved,and 69.52% were induced intravenously. CONCLUSION: It is urgent to intensify clinic publicity and training on ADR,establish effective ADR monitoring system and thoroughly motivate medical staff's enthusiasm to raise the reporting rate of ADR.

Objective: The effects of magnesium on the oxidation of low density lipoprotein (LDL) were systematically investigated by two different oxidation systems. Methods: LDLs were isolated from pooled healthy human fresh sera by ultracentrifugation. Oxidation of LDL was induced by adding Cu 2+ or co-cultured with cultured human umbilical vein endothelial cells. Conjugate diene was measured to assess the susceptibility of LDL to oxidation. The extent of LDL modification was determined by measuring the formation of thiobarbituric acid reaction substances (TBARS). Results: (1)The presence of Mg 2+ resulted in a protracted lag phase at doses of 0.3 mmol/L, 0.6 mmol/L, 1.2 mmol/L, and 2.4 mmol/L, as well as decreased production of TBARS when LDL was oxidized by the addition of Cu 2+ , at doses of 0.3 mmol/L and 0.6 mmol/L Mg 2+ .(2)Treatment of LDL with Mg 2+ (0.3 mmol/L, 0.6 mmol/L, 1.2 mmol/L, and 2.4 mmol/L) reduced the production of TBARS during endothelial cell-mediated LDL oxidation, P

Objective:The effect of magnesium on lipid peroxidation of endothelial cells induced by H 2O 2 and t bultyl hydroperoxide and subsequent alterations of extracellular superoxide dismutase(EC SOD) and cellular selenium dependent and selenium independent GSH Px were studied. Methods:The extent of cellular lipid peroxides was determined by measuring the formation of TBARS, EC SOD by the method of pyrogallol auto oxidation, and GSH Px by the method of DTNB. Results:The results showed that the formation of TBARS was significantly reduced in the group of H 2O 2+Mg 2+ at doses of 0.3, 0.6, 1.2,and 2.4 mmol/L compared to the group of H 2O 2(P

Objective: To investigate the effect of Mg 2+ on oxidative DNA damage of cultured human umbilical vein endothelial cells. Methods: The single-cell gel electrophoresis was used to determine the frequencies of cells with tail moment (TM) and the tail lengths. Results: The supplementation of Mg 2+ in the incubation medium influenced the H 2O 2-induced oxidative DNA damage. When compared with the group of H 2O 2, the frequencies of cells with TM and the tail lengths were markedly decreased in the group of H 2O 2+Mg 2+ at all doses (P

Objective: To study the effect of Mg 2+ onc fos, c jun, p53 and ref 1, that are transcription factors related to redox regulation, in cultured human umbilical vein endothelial cell. Methods: Imunohistochemistry techniques and image analysis system were used. Results:In the group of H 2O 2, the expresson of c fos, c jun, p53 and ref 1 was increased compared to the normal control group (P

Objective To evaluate the clinical efficacy and safety of long-term repeated treatment of facial wrinkles with application of botulinum toxin A (BTXA). Methods A total of 52 patients had received 8 injections in seven years with BTXA against facial wrinkles, including forehead wrinkles, fishtail lines, glabellas wrinkles, and nasal dorsum transverse wrinkles. Besides day 1 (baseline) and day for the next injection (end-point), follow-up visits were scheduled on 1 week, 1 month, and 3 months after every injection. The therapy effect and safety were evaluated. Results For all the patients, it began to take effect on day 3 or 4 after the treatment and best effect appeared on 1 month post-treatment. Patients' selfevaluation as grade 1 for the improvement of forehead wrinkles, fishtail lines, glabellas wrinkles and nasal dorsum transverse wrinkles, accounted for 100%, 97.1%, 99.8% and 99%, respectively. Correspondingly, cases as grade 2 accounted for 0, 2.9%, 0.2% and 1.0%. Grades 3 to 5 had not been reported. With the repetition of treatment, the efficiency increased. The average of effective duration was (7.8±1.1) months, which lasted longer with the injection times increased (r= 0.256, P= 0.02). Adverse reactions observed in the previous several injections, including ecchymosis, feeling of tightness, rigid expression and severer wrinkles near the injected site, which were mild and the incidence rate decreased after the following injections (r= 0.850, P= 0.01). Severe adverse effects, such as allergic reaction,headache, blepharoptosis and dysraphism of eyes had not happened in all the 52 patients. Conclusion Long-term repeated application of BTXA against facial wrinkles is safe and the efficacy is confirmed. The approach can be applied repeatedly to those who have indications and good tolerance.

OBJECTIVE To investigate the effect of nuclear factor-kappa B ligand-receptor activator of nuclear factor-kappa B-osteoprotegerin(RANKRANKL-OPG)system on bone resorption in middle ear cholesteatoma,and the reasons why middle ear cholesteatoma in children were more aggressive. METHODS The expression of RANKL and OPG in 21 adults cholesteatoma,17 children cholesteatoma and 18 normal external meatal skin was studied with immunohistochemistry. Semiquantitative analysis was used for comparison and statistical analysis. RESULTS RANKL-positive cells and the ratio of RANKL/OPG in cholesteatoma were significantly higher than that in external meatal skin(P

AIM: To observe the protective effects of losartan and astragalus membranace on the kidney of diabetic rats, and to study their possible mechanisms. METHODS: The diabetic rats were induced by a single intraperitoneal injection of streptozotocin. At the end of 12th week,changes in urinary albumin excretion, urinary ? 2-MG excretion, Ccr,NO,ET-1 levels in blood, urinary and renal tissue were observed. Serum and urinary TGF-? 1 concentration,average volume of glomeruler,average thickness of glomerular basement membrane were also measured. RESULTS: In the treated diabetic rats, urinary albumin excretion, urinary ? 2-MG excretion, Ccr, urinary and renal tissue NO, urinary TGF-? 1, average volume of glomeruler, average thickness of glomerular basement membrane decreased obviously as compared with diabetic untreated rats. These effects were enhanced when losartan was combined with astragalus membranace. CONCLUSION: Losartan or astragalus membranace reversed the injury of renal structure and function in STZ-induced diabetic rats. The protective effects were enhanced when losartan was combined with astragalus membranace. The decrease in NO,ET,TGF-? 1 concentration in renal tissue may be one of mechanisms for this action.

Objective:To explore the plasma catecholamines (CAs) concentration of postnatal depression and to analyze the relationships between postnatal depression and CAs level. Methods:Using high performance liquid chromatography (HPLC) to measure the subjects' plasma noradrenaline (NE)?adrenaline (E) and dopamine (DA) concentration. The postnatal depression group was compared with depression, ante partum and normal group.Results: NE level of plasma in the depression group and the postnatal depression group were all higher than those of normal group P 0.05) .Conclusion:the plasma NE increase is relative to postnatal depression episode,the plasma DA may be relative to postnatal depression episode. The relationship between plasma and postnatal depression remains unclear.

Objective To explore the value of asthma journal and corresponding monitoring of pulmonary ventilation function in treating bronchial asthma with the existing classification of asthma severity as control.Methods After 137 patients with bronchial asthma were evaluated according to the existing grades,they kept asthma diaries and received corresponding monitoring of pulmonary ventilation function at least 5 times per day,and all of the above clinical data were analyzed by relevant statistical methods.Results Among the 126 patients who completed monitoring,only 61(48.41%) patients could be graded by the Guide for Prevention and Treatment of Bronchial Asthma;27(21.43%) patients felt sensitive while 33(26.19%) ones felt insensitive.Conclusion The corresponding monitoring can not only accurately evaluate the severity of patients' bronchial asthma condition,but also detect those patients with deviated symptom perception.
