ObjectiveTo investigate the effect of Naoxueshu oral liquid on cerebral hemorrhage caused by hypertension. Methods140 patients with cerebral hemorrhage were randomly dividied into two groups with a 1∶1 ratio,treatment group and control group. Patients in treatment group received Naoxueshu oral liquid 30 ml daily,while that in control received Naoxuekang oral liquid 30 ml daily. The changes of score on Chinese medical integration,National Institutes of Health (NIH) Stroke scale and the volume of intracranial hemorrhage were evaluated before and a month after treatment.ResultsThe decrease of NIH score of patients in treatment group was (12.73±3.94),but(4.72±3.01) with the control's (t=13.5327,P<0.001). The decrease of the volume of intracranial hemorrhage of patients in treatment group was (13.28±4.17) ml,but (8.37±7.24) ml with the control's(t=4.9228,P<0.001). ConclusionComparing with Naoxuekang,Naoxueshu can accelerate absorption of hematome and ameliorate the recovery of neurological disability more efficiently.

ObjectiveTo evaluate the diagnostic performance of CTCA in predicting myocardial perfusion defects through comparative analysis between MPI defects and severity of coronary stenosis on CTCA.MethodsFour hundred and seventy-eight patients who underwent CTCA and 99Tcm-MIBI MPI in the same period were analyzed retrospectively.According to the severity of coronary stenosis judged by visual evaluation of the vessel diameter,the patients were divided into five groups:no stenosis,mild stenosis,moderate stenosis,severe stenosis and total occlusion.MPI results were classified as negative or positive for perfusion defects,and the prevalence of perfusion defects in every group was calculated per-patient and per-vessel basis.The cut-off of stenotic severity for predicting myocardial perfusion defects was designated as 50％ or 75％,with MPI as standard reference.True positive,true negative,false positive and false negative statistics were thus determined separately on patient and vessel basis.The diagnostic performance for CTCA were calculated and compared.Pearson Chi-square and its partition tests or Fisher exact test were used to compare ordinal variables.ResultsFifty-eight patients showed myocardial perfusion defects.Either by patientbased or vessel-based analysis,the prevalence of myocardial perfusion defects showed an increasing trend with greater coronary artery stenosis in each group,and there were statistical differences among them (x2 =116.62 and 483.83,both P ＜ 0.05).On patient-based analysis,sensitivity ( SN),specificity ( SP),positive predictive value( PPV),negative predictive value(NPV) and accuracy (AC) for CTCA predicting myocardial perfusion defects were 62.1 ％ ( 36/58 ) and 34.5％ ( 20/58 ) (x2 =8.84,P ＜ 0.05 ),84.5％(355/420) and 97.1％ (408/420) (x2 =40.16,P ＜0.05),35.6％ (30/101) and 62.5％ (20/32) (x2 =7.19,P＜0.05),94.2％ (355/377) and 91.5％ (408/446) (x2 =2.18,P ＞0.05),81.8％ (391/478)and 89.5 ％ (428/478) (x2 =11.66,P ＜ 0.05 ) when the cutoff was set to 50％ and 75％,respectively.On vessel-based analysis,the SN,SP,PPV,NPV and AC for CTCA predicting myocardial perfusion defects were 58.8％ (40/68) and 30.9％ (21/68) (x2 =10.73,P ＜ 0.05),95.9％ (1768/1844) and 99.0％ (1826/1844) (x2 =36.72,P ＜ 0.05 ),34.5％ (40/116) and 53.8％ (21/39) (x2 =4.59,P ＜0.05 ),98.4％ (1768/1796) and 97.5％ ( 1826/1873 ) (x2 =4.14,P ＜ 0.05 ),94.6％ ( 1808/1912 ) and 96.6％ ( 1847/1912 ) (x2 =10.31,P ＜ 0.05 ),respectively.ConclusionsThe prevalence of myocardial perfusion defects correlates positively with the severity of coronary stenosis seen on CTCA.CTCA may predict perfusion defects with high SP and NPV.However,the PPV of CTCA in predicting myocardial perfusion defects is poor when the stenosis cut-off is set at 50％.It is significantly improved when the cutoff value is set at 75 ％.

Objective： This study was designed to evaluate the clinical experience of esophageal replacement with colon (ERC). Methods： Among 51 patients, 6 with benign stricture and 45 with esophageal carcinoma, all of them were performed cervical esophagocologastrostomy. Among 51 patients, 48 patients received ERC by the transverse colon, including isoperistaltic anastomosis (27/48) and antiperistaltic anastomosis (21/48); three patients received ERC along the peristaltic direction by the right-side colon. In these patients, 24 cases were supplied blood by the arteria colica media and 27 cases by the arteria colica sinistra. Results： There was no operative death in the whole group. The postoperative complications consisted of leakage of cervical anastomosis(2 cases), cervical wound inflammation(3 cases), laryngeal recurrent nerve injury (1 cases), lung inflammation (3 cases). Conclusion： The authors conclude that colon was rich in blood and enough in length so that it can be grafted into neck and anastomosed with the esophagus and the result is satisfactory. Improved surgical technique can reduce the incidence of complications of ERC.

Objective To study the inhibitory effect of signal transducer and activator of transcription 3 (STAT3) shRNA generated by vector pSilence in conjunction with radiotherapy on laryngeal squarnous cell carcinoma of nude mice xenograft tumor. Methods The animal models of xenotransplanted human laryngeal carcinoma cell line Hep-2 were set up in 28 nude mice which were divided into 4 groups at random: the negative plasmid control group, the group that received pshSTAT3 (pGPU6/GFP/Neo-shSTAT3) transfecion, the radiation group, and the group of pshSTAT3 transfection combined with irradiation. Tumor volume was determined regularly. On the fifteenth day after termination of radiation treatment, the mice were sacrificed, the tumor weight was measured in all the groups, the inhibition rate for tumor growth was calculated and tumor growth curve was plotted. Meanwhile, the expressions of p-STAT3, B cell lymphoma 2 (bcl-2), p53, vascular endothelial growth factor(VEGF) protein and intratumor microvessel density (MVD) were observed by immunohistochemistry. Computer-assisted image analysis was used to obtain the results. Flow cytornetry was used to detect the cell apoptosis rate. Results There was a significant difference in tumor volume among the groups (P < 0. 01). The rate of tumor inhibition in the pshSTAT3 group, radiation group and pshSTAT3 plus radiation group was 19. 68%, 34. 76% and 67.70%, respectively. The p-STAT3 protein expression decreased significantly in the group of pshSTAT3 plus simple radiotherapy (P < 0. 01). The intratumoral MVD in the group of pshSTAT3 plus simple radiotherapy was significantly lower compared to the negative plasmid control group and the radiotherapy group (P < 0. 01), while the apoptosis rate was much higher (P < 0. 01). There was a positive correlation between the expressing of p-STAT3 and bcl-2, p.53, VEGF and MVD(r value was 0. 738,0. 727,0. 735,0. 691, all P <0. 01), and there was a negative correlation concerning cell apoptnsis rate. Moreover, a statistically positive association was present between MVD and p.53, VEGF protein expression, respectively(r value was 0. 784, 0. 641 ,all P <0. 01) ; and the correlation was negative between expression of bcl-2 and apoptosis rate(r=-0. 883 ,P < 0. 01). Conclusions Using psb.STAT3 in conjunction with radiotherapy can significantly inhibit the growth of laryngeal carcinoma.

Objective To investigate the causes of bicycle injuries among middle school students in rural areas and attitudes of students, their parents and teachers toward bicycle injuries.Methods 103 respondents in 14 groups were interviewed using focus group discussion outline. Data were taped and interpreted by two experienced researchers using the QSR NVivo 8.0 software.Results Disobeying the traffic rules, riding bicycle carelessly and fast speed when riding bicycle were the first leading causes of bicycle injuries among middle school students. The relative importance of disobeying traffic rules, inattentive riding the bicycles and fast speed were 1.00, 0.80 and 0.78respectively. Students, their parents and teachers held different attitudes toward the determinants of road condition(23 person-time)'. Fast riding speed was the most important subjective cause (students and parents were 14 and 8 person-time during the interview)but teachers thought that disobeying traffic rules was the most important one(by 14 person-time). Conclusion Residents in rural China had low awareness of child bicycle injuries. There is a need to improve the awareness of road safety among rural residents. Future intervention strategies should be tailored to address main determinants to reduce the incidence of road traffic injuries among children.

OBJECTIVE Lapachol is a natural naphthoquinone compound that possesses extensive biological activities. The aim of this study is to investigate the inhibitory effects of lapachol on rat C6 glioma both in vitro and in vivo, as well as the potential mechanisms. METHODS The antitumor effect of lapachol was firstly evaluated in the C6 glioma model in Wistar rats. The effects of lapachol on C6 cell proliferation, apoptosis and DNA damage were detected by 3-(4,5-dimethylthiazol-2-yl)-5-(3-carboxymethoxyphenyl)-2-(4-sulfophenyl)-2H-tetrazolium (MTS)/ phenazinemethosulfate (PMS) assay, hoechst 33358 staining, annexinⅤ-FITC/PI staining, and comet assay. Effects of lapachol on topoisomerase I (TOP I) and topoi?somerase Ⅱ (TOP Ⅱ) activities were detected by TOP Ⅰ and TOP Ⅱ mediated supercoiled pBR322 DNA relaxation assays and molecular docking. TOPⅠ and TOPⅡ expression levels in C6 cells were also determined. RESULTS High dose lapachol showed significant inhibitory effect on the C6 glioma in Wistar rats (P<0.05). It was showed that lapachol could inhibit proliferation, induce apoptosis and DNA damage of C6 cells in dose dependent manners. Lapachol could inhibit the activities of both TOPⅠ and Ⅱ. Lapachol-TOPⅠ showed relatively stronger interaction than that of lapachol-TOPⅡ in molecular docking study. Also, lapachol could inhibit TOPⅡ expression levels, but not TOPⅠ expression levels. CONCLUSION These results showed that lapachol could significantly inhibit C6 glioma both in vivo and in vitro, which might be related with inhibiting TOPⅠ and TOPⅡ activities, as well as TOPⅡ expression.

OBJECTIVETo observe and assess the immunosuppressive effect of applying bailing capsule (BLC, a dry powder preparation of Cordyceps sinensis mycelia), after renal transplantation, its influence on other systems of organism, and to explore the possible therapeutic mechanism.

METHODSOne hundred and twenty-one recipients of renal homo-allograft were randomly divided into two groups. The 64 cases in Group A was treated with cyclosporin A (Cs A) + prednisone (pred) + azathioprine (Aza), the 57 in Group B treated with Cs A + pred + BLC. They were followed-up for 1-2 year by checking up blood routine, urine routine, liver and renal function, blood electrolytes, glucose and lipids, and uric acid for 2 times every week in the first month after transplantation, followed by proper re-examination of these items according to various condition.

RESULTSThere was no significant difference between the two groups in aspects of graft survival rate, occurrence of reject reaction, renal function recovery, blood electrolytes and blood glucose levels. However, as compared with Group A, in Group B, levels of urinary erythrocytes and leucocytes, blood alanine transaminase (ALT), aspartate aminotransferase (AST), total cholesterol, uric acid as well as the incidence of infection were significantly lower, and blood high density lipoprotein, serum total protein, albumin, RBC and WBC count were significantly higher.

CONCLUSIONBLC could effectively prevent the reject response after renal transplantation, protect renal and liver function, stimulate hemopoietic function, improve hypoproteinemia and hyperlipidemia, reduce the infection, etc., therefore, it is an ideal immunosuppressor after organ transplantation.
