Objective To investigate the change and significance of electrocardiogram and myocardial damage index in patients with acute organophosphorus pesticide (AOPP).Methods 71 hospitalized patients in EICU with AOPP from January 2000 to June 2006 were recorded.The patients were divided into 3 groups: mild poisoning group (n=18),moderate poisoning group(n=22) and severe poisoning group (n=31).Electrocardiogram(ECG), serum creatine kinase(CK), serum creatine kinase isoenzyrne MB(CK-MB),lactate dehydrogenase(LDH) and TnI were detected,the relation between the above-mentioned indexes and the toxical degree were analyzed.Results Abnormal ECG had a rasied tendency along with increase of the poisoning degree.The incidence of Ⅱ~Ⅲ atrioventricular block, atrial premature beats, ventricular premature contraction, ventricular tachycardia and ventricular fibrillation in severe poisoning group significantly increased compared with that in mild poisoning group and moderate poisoning group(P

Fluorescence in situ hybridization (FISH) is a kind of technique that uses fluoreseently la-beled DNA probes to assess cells for genetic alterations. UroVysion is a technique that uses FISH to detect bladder cancer in the voided urine by four fluorescently labeled DNA probes to the pericentromeric regions of chromosomes 3 ( CEP3 ) ,7 (CEPT), and 17 (CEP17) and to the 9p21 locus ( LSI 9p21 ) location of the p16 tumor suppressor gene. It is reported that sensitivity of FISH was higher than cytology for the detection of all stages and grades of bladder cancer. FDA has approved UroVysion for the detection of recurrent bladder cancer in voided urine specimens from patients with a history of bladder cancer in the year 2001 and from pa-tients with gross or microscopic hematuria but no previous history of bladder cancer in the year 2005. Fur-thermore, UroVysion can benefit the assessment of bladder cancer patients receiving BCG treatment.

OBJECTIVE To survey the distribution and diversity of bacteria among COPD patients in our hospital′s comprehensive intensive care unit(ICU).METHODS All 166 strains of bacteria were divided into three groups:from noninvasive positive pressure ventilation,from mechanical ventilation and from standard medical treatment and compared their difference.RESULTS The most common pathogens were Candida albicans(38.8%),Klebsiella pneumoniae(10.2%) and Escherichia coli(8.2%) in the standard medical treatment group;C.albicans(45.5%),Pseudomonas aeruginosa(9.1%) and K.pneumoniae(9.1%) in the noninvasive positive pressure ventilation group;however,P.aeruginosa(23.2%),C.albicans(17.9%)and Acinetobacter baumannii(12.6%) in the mechanical ventilation group,respectively.Accompanying with the mechanical ventilation,the resistant-drug rates were observably increased.CONCLUSIONS The percentage of Gram-negative bacilli and fungal infection in the COPD patients of comprehensive ICU is very high.So we should supervise and control the results of antibiotics susceptibility.

Objective By reviewing the relevant literature, we explored the current status and problems of the evaluation of the training effectiveness, and put forward the corresponding countermeasures, in order to provide a theoretical basis for the effect evaluation of nurse training in China. Methods By searching Citation online search and integration system (CITE), the Chinese biomedical literature service system (CBM), we included the literatures on the effect evaluation of the nurses training in the core journals from January 2006 to November 2015. Retrieval literatures were imported the bibliographic management software Note express by database. The corresponding field were analyzed in the literature′s age distribution, evaluation object, evaluation model, evaluation method, evaluation index and evaluation tool, et al. Results There were 343 literatures had retrieved, the total number of literatures presented a increasing tendency. The evaluation methods, evaluation tools and evaluation indicators presented a tendency of diversity, and the evaluation model was relatively single. Only 16 (4.7%) literatures tried to construct the training effect evaluation system of nurses, which was not based on some theory or hypothesis, which had not been effectively put into practice. Conclusion The effect evaluation system of nurse training needed to be done in depth, such as reconstruction of the new training evaluation model, the establishment of training evaluation system of different professional, different levels, different positions, to research evaluation methods, evaluation criteria and clinical practice testing, to design, training evaluation management software etc.

Objective　To investigate the effects of TNP-470 on the growth of a human malignant glioma cell line SHG-44 in vivo and in vitro. Methods　The colorimetric MTT assay, soft agar culture, flow cytometry，light and electron microscopy were used to determine the proliferation, the cloning efficiency, cell cycle and the morphological changes of SHG-44 cells as well as the growth of its xenografted tumor. Results　TNP-470 (20～2 000 ng/ml) significantly inhibited the proliferation of SHG-44 cells in vitro (the 50% inhibitory concentration was 200 ng/ml). Cloning efficiency reduced obviously. The number of cells in G0/G1 phase increased, while that in S, G2/M phases decreased significantly. Weight and volume of xenografted tumors treated with TNP-470 (30 mg/kg, injected subcutaneously every other day) reduced notably. Furthermore, there were necrotic area and apoptosis in the tumor. No severe side effect of TNP-470 was found in this study. Conclusion　The inhibitory effect of TNP-470 on the growth of SHG-44 cells correlates with its functions of regulating cell cycle and inducing apoptosis, which suggests that the angiogenesis inhibitor TNP-470 has strong inhibitory effect on human malignant gliomas.

Objective To retrospectively study the clinical features in elderly patients with epilepsy.Methods Clinical data of 72 elderly patients with epilepsy aged over 60 years from outpatients and inpatients were studied.Results In the 72 cases,cerebrovascular disease associated with epilepsy occurred in 52 cases (72.2％),with partial seizures in 50 cases (69.4％),and with generalized seizures in 22 cases (30.6％).In 38 cases with epilepsy secondary to cerebral infarction,the cerebral cortex infarction occurred in 26 cases (68.4％).In 14 cases with epilepsy secondary to cerebral hemorrhage,cerebral cortex hemorrhage occurred in 11 cases (78.6％).In interictal electroencephalogram (EEG) of the 72 cases,8 cases had normal EEG (11.1％),64 cases had abnormal EEG (88.8％).31 cases (48.4％) presented with sharp wave,spikes wave or tip--slow composite wave,33 cases (51.6％) presented with low amplitude of slow wave activity,which were non-specific abnormalities.Conclusions The main cause of seizures in the elderly is cerebrovascular disease.Partial seizures is the main type of seizure.Most of seizures caused by cerebrovascular disease occur in the region near the cortex.

Objective:The benefits of postoperative adjuvant therapy method for low-risk early-stage cervical squamous cell carcinoma were investigated. Methods:A total of 133 patients with low-risk early-stage cervical squamous cell carcinoma were treated at Shandong Cancer Hospital&Institute from February 2008 to March 2012. All patients received adjuvant therapy:42 were treated with pelvic ra-diotherapy (RT), 47 were treated with adjuvant chemotherapy (CT)+intracavitary radiotherapy (ICRT), and 44 were treated with concurrent chemoradiation (CCRT). Disease-free survival (DFS) and complications of the therapy were evaluated. Results:No significant differences in DFS were observed in the patients treated with RT, CT+ICRT, and CCRT (P>0.05), and the three-year DFS rates were 94.0%, 93.4%, and 97.6%, respectively. The frequencies of grade III to IV acute toxicities were significantly higher in patients treated with CCRT (34.1%) than in those treated with RT (9.5%) or CT+ICRT (16.7%) (P<0.05). No statistically significant difference was observed between the RT group and the CT+ICRT group (P>0.05). Grade I to II late toxicity was significantly more frequent in the CCRT (25%) and RT (19.0%) groups compared with the CT+ICRT group (4.3%) (P>0.05), but no statistically significant differences were observed between the CCRT and the RT groups (P>0.05). Conclusion:CT+ICRT or RT has a three-year DFS rate equivalent to CCRT but with fewer therapy com-plications for low-risk early-stage cervical squamous cell carcinoma.

ObjectiveTo investigate the therapeutic effect of human umbilical cord mesenchymal stem cell-paracrine substance on fulminant hepatic failure (FHF) rat, and to study the effect on liver function and hepatocyte proliferation. MethodsMesenchymal stem cells(MSCs)were separated from human umbilical cord, and surface makers of cells were detected by flow cytometry. Human umbilical cord mesenchymal stem cells-conditioned medium(MSC-CM) was prepared. FHF rat model was induced by intraperitoneal injection of D-galactosamine and they were randomly diveded into three groups: MSC-CM group, NS group, PHGF group. 24 h later, 1 ml MSC-CM, 1 ml 0. 9% NaCl solution and lml PHGF solution was injected into the tail vein of MSC-CM, NS, and PHGF rats, respectively. In each group (n=8 per group), blood samples were collected at 12, 24, 36, and 60 h after treatment from inner canthus for analysis of blood ALT and TBIL levels. We used five rats per group for tissue collection after sacrifice at 36 h after treatment and 10 animals per group for survival analysis. PCNA immunohistochemical staining was used in the sections of liver tissue to detect hepatocyte proliferation. Results24 h after treatment, the levels of ALT and TBIL in the MSC-CM and PHGF groups were lower than those in the NS group(P＜0. 05), but there was no significant difference between the MSC-CM and PHGF groups. There were more PCNA-positive hepatocytes in the MSC-CM and PHGF groups than in the NS group(P＜0.01), but there was no significant difference between MSC-CM and PHGF group. Survival analysis found that the survival rate of rats in the MSC-CM and PHGF groups was higher than that of rats in the NS group (P=0. 049), but there was no significant difference between the MSC-CM and PHGF group. ConclusionsThe paracrine substance of human umbilical cord mesenchymal stem cells can stimulate hepatocyte proliferation and improve liver function of FHF rats, potentially creating a new avenue for the treatment of FHF.
