OBJECTIVE: To investigate the features of adverse drug reaction(ADR) in our hospital and evaluate the quality of ADR report in order to promote rational clinical drug use and find out the existing problems in the report. METHODS: Microsoft Excel was designed to analyze statistically the sex and age of the patients,category of the used drugs and the clinical manifestations of ADR in 311 cases of ADR report collected between 2002 and 2005.RESULTS: The occurrence of ADR induced by antibacterials ranked the first.ADR affecting skin and its appendages counted for 50% of the total.The numbers of ADR reports were found to be less than expected.CONCLUSIONS: Professional staff training should be strengthened,the use of antibacterials should be rationalized to lessen and avoid the occurrence of ADR.

Objective:To analyze the cause of the blood heat syndrome in psoriasis.Methods: Made the investigation form about information of psoriatic patients through DME method and reference both Chinese and foreign documents,analyzed main component of data by SAS software.Results: The first main component of blood heat syndrome in psoriasis are infection,drinking,dietetic problem,and emotion;the second main component is family history;the third main component is dampness;the forth main component is the allergy to the food;the fifth is outside irritation.Through the corresponding investigation we found that food include hot food,beef,sheep and sea food,emotion problem include over work and stress,dampness include work and living in humid place for long time,outside stimulus meant chemical stimulus.Conclusion: The main cause of the blood heat syndrome in psoriasis are infection,drinking,dietetic problem,and emotion,family history,humidity,allergy to the food and chemical stimulus in order.

Aim To investigate the age-related changes of TrkB mRNA in hippocampal formation of aged rats,and the effects of ginsenosides(GS),and provide reliable experimental evidence for anti-aging.Methods 24 Wistar female rats were randomly divided into 3 groups: Young,aged and GS group(fed with GS from 17 to 27 months).In situ hybridization(ISH) method was applied into qualifying and quantitating the TrkB mRNA expression in hippocampal formation.Results TrkB mRNA expression in aged CA3,CA1 and dentate gyrus decreased by 24.2%,13.4% and 50.6%(P

HIF-1 is composed of HIF-1α and HIF-1β subunits. It promotes target genes transcription under hypoxia and plays essential roles in cell development, physiological adaptations, and pathological processes. In the past 10 years, the research on signaling pathways of HIF-1 in response to cell hypoxia stress, especially on HIF-1α-mediated gene transcription has made great progress.

Objective To study the relationship between hepatocellular carcinoma and the interaction of polymorphisms in DNA repair gene XPD with environmental factors. Methods A hospital-based ease-control study on hepatoeellular carcinoma was conducted. All the hepatocellular carcinoma eases (n=300) were newly diagnosed and controls (n=312) were diagnosed with non-tumor cases. XPD genotype (Lys751 Gin and Asp312 Ash) from blood derived DNA was determined using TaqMan MGB Real-time PCR. Unconditional logistic regression was used to estimate the odds ratios (ORs) and 95% confidence intervals (CIs). Results For XPD condon 751 genotypes, there was no significant difference between frequencies of the AC or CC among patients and controls (P>0.05) (referent AA). The frequency of XPD312A allelic gene was higher in eases than that in controls and was associated with an increased risk (adjusted OR = 2.62,95% CI: 1.626-4.222) for hepatocellular carcinoma when compared with GG genotype. Interactions were found between infection of HBsAg and XPD312 (OR=7.348), as well as between smoking and non-wild type gene of XPD751 (0R=4.291) and XPD312 (OR=5.341). Conclusion DNA repair XPD312A allelic gene might increase the risk of Hepatocellular carcinoma. Interactions between HBsAg infection, smoking and XPD were observed in Hepatocellular carcinoma.

The clinical value of transvaginal ultrasound in clinical surgical treatment of cesarean scar pregnancy (CSP) was evaluated.The clinical data of 104 patients with CSP admitted at Tongji Hospital from 2013 to 2016 were collected and analyzed retrospectively,including the patients' age,gestational age,the size of gestational sac or uneven mass,the uterine scar thickness,β human chorionic gonadotropin (hCG) levels and so on.Of these 104 cases,30 cases were subjected to laparotomy,29 cases to laparoscopy,27 cases to hysteroscopy,16 cases to ultrasound-guided uterine curettage,and 2 cases to conservative treatment.The transvaginal ultrasound showed that uterine scar thickness and gestational sac or uneven mass size had significant difference (P＜0.05) among different surgical methods by comparatively analyzing the patients' data.It was suggested that transvaginal ultrasound may provide the valuable reference for choosing clinical surgical procedures for CSP.

OBJECTIVETo identify the effect of NEP on Abeta -induced apoptosis in PC12 cells.

METHODSPC12 cells that stably express NEP is generated and the effect of NEP on the process of apoptosis induced by Abeta is analyzed, including the viability of the cells, the production of LDH, ROS and ATP, the activity of Caspase-3.

RESULTSNEP could improve the viability of cells and the production of ATP, inhibit the release of LDH and ROS. In the same time, the activity of caspase-3 descended (P < 0.05). But iNEP had not significant effect on cells apoptosis (P > 0.05).

CONCLUSIONNEP has the protective effect on Abeta-induced apoptosis in PC12 cells.

OBJECTIVETo explore the function of Caspase-3 and p38 MAPK in MMT-induced apoptosis in PC-3M cells.

METHODSAfter incubation of PC-3M cells with 1 mmol/L MMT, the activity of Caspase-3 was examined. The influence on cells viability of Z-DEVD-FMK, a Caspase-3-specific peptide inhibitor, was also examined. Western blot was used to examine the change of p38 MAPK. The effect on cells viability and Caspase-3 activity of SB203580, a specific inhibitor of p38 MAPK, were also examined.

RESULTSThe activity of Caspase-3 increased significantly in MMT-induced apoptosis in PC-3M cells /9P < 0.01), and Z-DEVD-FMK could protect cells from apoptosis (P < 0.01). In this course, the phosphorylation of p38 MAPK could be observed. SB203580 inhibited Caspase-3 activity (P < 0.05) and prevented PC-3M cells from MMT-induced apoptosis (P < 0.05).

CONCLUSIONCaspase-3 and p38 MAPK are involved in MMT-induced PC-3M cells apoptosis.
