Objective To evaluate the efficacy and adverse events of oxcarbazepine(OXC) on the children with partial epilepsy.Met-hods Sixty-four children with partial epilepsy were divided into 2 groups.Forty-one newly diagnosed patients who had never accepted standard therapy entered monotherapy group,and 23 patients who had many anti-epileptic drug(AEDs) in turn with poor efficacy served as add-on therapy group.The initial dose was 4-8 mg/(kg?d).The dosage was increased by one time every 2 weeks,and should not exceed 10 mg/(kg?d) in each time.The maintenance dose was 28-40 mg/(kg?d).With open-label autocontrol method,the efficacy and adverse events of OXC were analyzed during the first 6 months of treatment both in 2 groups.Results The effective rates were 85.4%,69.6% and 79.7%,in monotherapy,add-on therapy and total groups.The seizure free rates were 53.7%,17.4% and 40.6%.It showed that the seizure frequencies between 2 groups at 6 months after therapy were significantly difference(P0.05).The common adverse events were dizziness,headache,fatigue and nausea.Six patients had dropped out because of rashes,however,they all recovered after drug withdrawal and nonspecific therapy.Conclusion The efficacy of OXC is sustained with good safety and tolerability profiles on the treatment of children patients with partial epilepsy.

OBJECTIVETo investigate the differences in the expressions of E-cadherin and N-cadherin between high-risk prostate cancer and low- and medium-risk prostate cancer, and analyze their correlation with the age, serum PSA level, and Gleason score of the patients.

METHODSWe retrospectively analyzed the clinical data of 42 cases of prostate cancer, which were divided into a low- and medium-risk group (group A, n = 15) and a high-risk group (group B, n = 27). We measured the expressions of E-cadherin and N-cadherin by immunohistochemical staining, compared their differences between the two groups, and analyzed their correlation with the age, serum PSA level, and Gleason score of the patients.

RESULTSImmunohistochemical staining showed that the expression of E-cadherin was significantly higher in group A than in B (6.1 +/- 0.51 vs 4.2 +/- 0.37, P < 0.01), and so was its positive rate (73.3% vs 25.9%, P < 0.05). The positive rate of E-cadherin was also markedly higher in the patients with serum PSA < 20 microg/L than in those with serum PSA > or = 20 microg/L (66.7% vs 29.6%, P < 0.05), and so was it in the patients with the Gleason score 5-7 than in those with 8-10 (60.9% vs 21.1%, P < 0.05). On the contrary, the N-cadherin expression was significantly lower in group A than in B (3.7 +/- 0.32 vs 7.5 +/- 0.58, P < 0.01), and so was its positive rate (13.3% vs 59.3%, P < 0.01). The positive rate of N-cadherin was also remarkably lower in the patients with the Gleason score 5-7 than in those with 8-10 (26.1% vs 63.2%, P < 0.05). However, there were no statistically significant differences in the N-cadherin expression between the patients with serum PSA < 20 microg/L and those with serum PSA > or = 20 microg/L (P > 0.05), nor in the expressions of E-cadherin and N-cadherin between the patients aged > or = 70 years and those aged < 70 years (P > 0.05).

CONCLUSIONThe expressions of E-cadherin and N-cadherin are significantly different between high-risk prostate cancer and low- and medium-risk prostate cancer, which suggests that both may correlate with the invasion and metastasis of prostate cancer as well as with the serum PSA level and Gleason score of the patients.

Objective To explore the effects of a single bout of aerobic exercise on oxidative stress and total peripheral vascular resistance. Methods 36 prehypertensive patients were divided into aerobic exercise group (n=18) and control group (n=18). The aerobic exercise group performed cycle ergometry at 70% maximal oxygen consumption for 30 min. Total peripheral vascular resistance (TPVR), malondialdehyde (MDA), mean arterial pressure (MAP), vitamin C (VC) and vitamin E (VE) were measured before, immediately, 1 hour and 2 hours after the aerobic exercise. Results There was no significant difference in TPVR, MDA, MAP, VC and VE between two groups before exercise (P>0.05). TPVR was all significantly lower in the aerobic exercise group than in the control group immediately, 1 hour and 2 hours after exercise (P<0.001), and showed a rising trend of recovery. MDA was significantly higher in the aerobic exercise group than in the control group 1 hour and 2 hours after exercise (P<0.05), however there was no significant difference in MDA between two groups immediately after exercise (P>0.05). MAP was significantly lower immediately after exercise in the aerobic exercise group than in the control group (P< 0.001), but there was no significant 1 hour and 2 hours after exercise (P>0.05). There was no significant difference in VC and VE between two groups immediately, 1 hour and 2 hours after exercise (P>0.05). Conclusion The level of oxidative stress increases after a single bout of aerobic exercise, and the TPVR decreases.

OBJECTIVE:To investigate characteristics and regularity of ADR induced by antineoplastic drugs and provide ref-erence for the safe drug use. METHODS:7 417 ADR reports induced by antineoplastic drugs from 91 hospitals from 2009 to 2013 were collected in the ADR monitoring center of PLA. According to the classification in national ADR monitoring cencer,Excel soft-ware was performed to statistically analyze the data. RESULTS:Among 7 417 ADR reports,1 475 were severe ADR(19.89%), 196 were the new and general ADR(2.64%),and 44 were new and severe ADR(0.59%);the elderly patients aged from 45-59 years accounted for the highest proportion (41.01%);intravenous administration was the main administration route causing ADR (88.96%);the incidence of antineoplastic drugs was higher in plant-derived drugs(26.55%),platinum drugs(24.86%)and an-ti-metabolism drugs (19.46%);ADR mostly manifested as lesions of digestive system (38.80%),blood system (16.53%) and general system(12.79%);43.60%ADR occurred within 12 hours after administration. CONCLUSIONS:Highly poisonous,nar-row-range security antineoplastic drugs could easily induce ADR. Risk prevention of antineoplastic drugs should be strengthened to undertake monitoring for high-risk patients and antineoplastic drugs,and severe ADR. More attention should be attached to the reac-tions after 12 h administration to reduce ADR incidence as much as possible.

OBJECTIVE:To investigate the condition and characteristics of drug-induced liver injury (DILI) of anti-infective agents and provide reference for the prevention and treatment of anti-infective agents related DILI. METHODS:Based on retrospective analysis,a total of 572 DILI reports of anti-infective agents were collected from PLA ADR monitoring center during 2009 to 2013, and then analyzed statistically in terms of patient’s age and gender,main diagonosis,categories of DILI-inducing drugs,type,route of administration,occurrence time,lab indicator,DILI types and clinical manifestations,the application of liver protective drugs,out-comes,etc. RESULTS:Among 572 DILI cases,there were 412 cases(72.03%)of male patients and 160 cases(27.97%)of female patients,and average age of the patients was(44.54±23.75)years old. ADRs were related to 57 kinds of anti-infective agents in 6 cat-egories. Rifampin was the most frequent in suspected drugs,followed by isoniazid,moxifloxacin,fluconazole,azithromycin,cefurox-ime, cefoperazone/sulbactam, levofloxacin, cefoxitin and voriconazole. Intravenous infusion was the main administration route (74.48%). The occurrence time of ADRs was mainly within two weeks (86.19%). Hepatocellular damage (93.33%) was the main type in 360 cases of ADR for evaluation of liver injury types. The majority of cases(82.17%)were cured or improved after drug with-drawal and symptomatic treatment. CONCLUSIONS:Cephalosporin,fluoroquinolones,antituberculosis and antifungal drugs might be the common agents which caused liver injury. Hepatocellular damage is the most frequent type. Most of patients have a favourable prognosis. Clinical medical staffs should strengthen the awareness of DILI caused by anti-infective agents and ehance the prevetion of it.

Traditional herbal medicines, Panax ginseng, Panax quinquefolium and Panax notoginseng, attract our attention for their extensive and powerful pharmacological activities. Ginsenosides are the main active constituents of these medicinal herbs. The related glycosyltransferases involved in ginsenoside biosynthesis are the key enzymes which catalyze the last important step. Modification of ginsenoside aglycones by glycosyltransferases produces the complexity and diversity of ginsenosides, which have more extensive pharmacological activity. At present, ginsenoside aglycones and compound K have been obtained by synthetic biology. As the last step of ginsenoside biosynthesis, glycosylation of ginsenoside aglycones has been studied intensively in recent years. This review summarizes the basic strategies and research advances in studies on glycosyltransferases involved in ginsenoside biosynthesis, which is expected to lay the theoretical foundation for the in-depth research of biosynthetic pathway of ginsenosides and their production by synthetic biology.
