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.

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.

Objective To explore the diagnosis and therapy experience of vascular ring combined with tracheal compression in infants and neonates.Methods Sixteen cases(including 7 boys and 9 girls,aged 1 day to 12 months)with vascular ring combined with tracheal compression hospitalized in Guangdong General Hospital from Jun.2004 to Dec.2009 were enrolled.In these 16 children,13 cases had congenital heart malformations.All children underwent X-ray,echocardiography and spiral computed tomography examination.Nine cases received bronchoscopy study.Fifteen cases performed surgical division of vascular ring with cardiopulmonary bypass and 1 case underwent vascular ring division and tracheoplasty.Eleven cases received management of congenital heart defect simultaneously.Results Vascular ring anomalies included pulmonary artery sling in 5 children,right aortic arch-left ligmentum/aberrant left subclavian artery in 8 cases,double aortic arch in 1 case,innominate artery compression in 1 case,and pulmonary sling combined with right aortic arch-aberrant left subclavian artery in 1 case.There were 2 ring-sling complex cases in this study.The diagnosis of vascular ring were correctly made by echocardiography in 7 children and made by spiral computed tomography in all 16 cases.Two cases combined with tracheal ring died.In the follow-up study of 11 cases,5 cases were still vulnerable to wheezing.Conclusions The common presentation of tracheal compression in infants and neonates associated with vascular ring are tachypea,stridor,and dyspnea.Multi-slices spiral computed tomography is an important imaging modality.Surgical divisions of vascular ring are safe procedure in most cases and tracheal compression can be relieved by this operation.In patients with severe tracheal stenosis,tracheoplasty should be recommended.

OBJECTIVETo study the clinicopathologic features and immunophenotype of desmoplastic small round cell tumor (DSRCT), and to assess the feasibility of reverse transcriptase-polymerase chain reaction (RT-PCR) as a diagnostic adjunct for DSRCT in routine practice.

METHODSThe clinical (number = 15), cytologic (number = 1) and histopathologic (number = 14) features of 15 cases of DSRCT were investigated. The immunophenotype was studied by LSAB method using a panel of antibodies. RT-PCR was performed in one case using formalin-fixed, paraffin-embedded tissue for EWS-WT1 fusion gene mRNA.

RESULTSAmong the 15 patients studied, 13 were males and 2 were females. Their age ranged from 12 to 38 years (mean age = 23.8 years). Most presented with vague abdominal discomfort, distension or pain, accompanied by nausea, constipation and weight loss. Physical examination showed a palpable abdominal mass with ill-defined borders and tenderness. Ultrasound and computerized tomographic examination revealed single or multiple nodular tumor mass(es) in the peritoneal cavity, measuring 3 cm to 25 cm in greatest diameter (mean tumor diameter = 8.6 cm). Cytologic examination in 1 case showed clusters of small round cells in a hemorrhagic background. The tumor nuclei were hyperchromatic and contained inconspicuous nucleoli. Mitotic figures were readily identified. The cytoplasm however was scant. Histologically, the tumor was composed of small, round, ovoid to spindled cells arranged in nests of various shapes and sizes, embedded in a desmoplastic and focally hyalinized stroma. Immuno- histochemically, all cases showed diffuse and strong staining for AE1/AE3, vimentin, desmin and neuron-specific enolase. Some of them also expressed CAM5.2, epithelial membrane antigen, CD57, chromogranin A, synaptophysin and WT1. They were all negative for myogenin, CK5/6, CD117, calretinin and CD99. RT-PCR successfully amplified the EWS-WT1 chimeric mRNA in 1 case using paraffin-embedded tissue. Subsequent DNA sequencing showed that the gene fusion involved exon 7 of EWS and exon 8 of WT1 genes. The fusion gene contained KTS sequence.

CONCLUSIONSDSRCT is a highly malignant small round cell tumor occurring predominantly in the abdominal or pelvic cavity of young to middle-aged males. It is characterized by multiphenotypic differentiation. The peculiar perinuclear dot-like staining pattern for vimentin and desmin is characteristic for DSRCT. EWS-WT1 fusion transcript can be detected in formalin-fixed, paraffin-embedded tissue by RT-PCR, which may thus serve as a useful diagnostic adjunct for DSRCT.
