OBJECTIVETo investigate the epileptic seizure-like effect of Sophora alkaloid sophoridine on electroencepholography (EEG) and its possible characteristic and the mechanism of the seizure-like effect.

METHODChronic electron implantation was employed for the intracranial electroencepholography (IEEG) recording in rat, and the traditional anti-seizure drugs were for the mechanism study in mice.

RESULTCompared with the medial perforant path (PP) area and the temporal cortex (TC), the granule cells in hippocampus dentate gyrus (DG) area is more sensitive in the kindling effect by sc sophoridine. Under-threshold hypnotic dosage of diazepam and the hypnotic dosage of pentobarbital sodium can block the sophoridine kinded seizure in mice, but the phenytoin sodium can not block the seizure, also the dosage of it can block the maximal electroconvulsive shock (MES) seizure.

CONCLUSIONSophoridine-induced synchronous oscillations in the hippocampus could elicit the generation and development of seizure. And the hippocampus might play the crucial role and be the original part of the seizure. Sophoridine kinded seizure might belong to clonic seizures, and the diazepam is the ideal agent for the treatment.

The educational level, duration of disease, patients′ age and management of medical and nursing were the influencing factors of disease knowledge, which could explain 44.3% of total variation. Conclusions The knowledge level among patients with ulcerative colitis needs to be improved.Nursing staff should be based on influencing factors, pay attention to improve the knowledge level of patients with nursing intervention or health education,through a variety of ways to meet the patients need of disease knowledge, improve theirquality of life.

Objective: To investigation HER2 status in gastric adenocarcinoma of Chinese and contributing factors to the HER2 expression. Methods: HER2 status of 40 842 gastric adenocarcinomas and clinical data were retrospectively collected from 23 hospitals dated from 2013 to 2016. The association between HER2 positivity and clinicopathologic features was analyzed. Results: Of the 40 842 patients the median age was 62 years, the male female ratio was 2.6∶1.0. The rate of HER2 positivity was 8.8% (3 577/40 842). HER2 expression was related to the tissue type, tumor location, Lauren classification and tumor differentiation (P values: 0.009, 0.001, <0.01 and <0.01, respectively). Different HER2 expression status was observed between primary and recurrent tumors in 7.6% (48/635) cases. The rates of HER2 positivity ranged from 2% to 10% among different institutions. The rates of HER2 FISH amplification were dramatically different among the 23 hospitals (0-100%) with an average rate of 10% (810/8 156) in patients with HER2 IHC 2+ . Conclusions HER2 expression is associated with clinicopathologic characteristics. HER2 re-assessment of tumor tissue and use of in situ hybridization techniques increase HER2 positivity. The current retrospective study should reflect the HER2 status in gastric adenocarcinoma of Chinese patients.

Objective To investigate the prevalence and associated risk factors of diabetes and prediabetes in Blang ethnic adults in Menghai county. Methods A cross-sectional survey including 3 365 Blang ethnic adults (aged 18 and above from 5 administrative villages) was conducted from February 2017 to March 2017 in Menghai county. A questionnaire, physical examination, and blood assays were included in the survey. Finally,a total of 3 237 adults with complete data were selected into this analysis. Results The standardized prevalence of diabetes and prediabetes in Blang ethnic adults were estimated based on the sixth national census in 2010. According to the 1999 WHO criteria, the overall standardized prevalence of diabetes and prediabetes were 8.5% (men: 10.2%, women: 6.8%) and 16.1% (men: 18.0%, women: 14.1%), in which the standardized prevalence of newly diagnosed diabetes among the total population was 7.3% (men: 8.7%, women: 5.8%). Multivariable multinominal logistic regression analyses showed that age, hypertension, hypertriglyceridemia, and central obesity were significantly positively associated with both diabetes and prediabetes, with the corresponding odds ratios of 1.74 and 1.37, 2.39 and 2.02, 2.30 and 1.34, 2.55 and 1.73, respectively. Conclusion The prevalence of diabetes is relatively high in Blang ethnic adults in Menghai county.
