Objective To investigate the effect of sodium ozagrel injection on hemorheology, endothelin (ET) and nitrogen monoxidum (NO) of patients with non-ST segment elevation myocardial infarction (NSEMI). Methods A total of 81 NSEMI patients were divided randomly into two groups: control group and experimental group. Isosorbide mononitrate, low molecular heparin and simvastatin were administered in the control group while sodium ozagrel was added to the experimental group apart from the above-mentioned drugs. The clinical effect of sodium ozagrel was observed. The changes in the indexes of hemorheology, ET and NO were analyzed. Results The clinical effect was significantly better in the experimental group than in the control group (P<0.05). The level of ET was obviously lower after treatment than that in the experimental group and the control group before treatment (P<0.05). The level of NO was obviously higher after treatment than that in the experimental group and the control group before treatment (P<0.05). The changes of ET and NO in the experimental group post-treatment were more significant than those in the control group after-treatment (P<0.05). The level of hemorheology index after treatment was lower than that before treatment in the experimental group (P<0.05). High-shear rate of whole blood viscosity, platelet adherence rate, and fibrin as hemorheology indexes were lower after-treatment than those pretherapy in the control group (P<0.05). Conclusion Sodium ozagrel injection could affect hemorheology,ET and NO of patients with non-ST segment elevation myocardial infarction. Thefore, the therapeutic efficacy can be better if sodium ozagrel is added to the conventional therapy.

Objective To retrospectively analyze clinical outcomes of brain metastases treated with Cyberknffe. Methods From Aug. 2006 to Aug. 2007, 40 patients with brain metastases treated with Cy-berknife in Tianjin Cancer Hospital were included. Totally 68 brain metastatic lesions were treated. The maximal diameter was 0.4 -7.5 cm (average 1.9 cm). The primary tumor of 35 patients was partial re-ponse or stable to the previous treatment at the diagnosis of brain metastasis. The geometric center of target volume was set as the isocenter and the nominal standard dose point. More than 95% target volume was cov-ered by 80% isodose surface. Hypofractionated radiation was 18 -36 Gy given in 1 -5 fractions of 5 -25 Gy. Results The Follow-up rate was 95%. The clinical symptom remission rate (including complete and partial remission) at one week after Cyberknife treatment was 90% (36/40). The therapeutic effective rate (CR + PR + SD) was 94% (64/68) after three months follow-up, which was evaluated by contrast-en-hanced CT or MRI. The 3-month local control and 1-year survival rates were 78% (53/68) and 68% (27/40). New brain metastatic lesions outside the radiation field occurred in 14 patients within 3 months, which was independent of age, whole brain irradiation, number or maximal diameter of original lesions, frac-tion dose, frequency or total dose of Cyberknife treatment. Conclusions Cyberknife, used as the primary treatment of brain metastases, can achieve good clinical outcomes.

Objective To explore the acute toxicity and LD 50 of Tripterygium Hypoglaucum (Levl) Hutch(THH) solution to provide information for safe clinical application. Methods After oral administration of THH solution in mice, the mortality and the physiological and pathological changes were observed. Results The LD 50 (95% confidence limit) of THH in male and female mice was 79 g/kg(69～89 g/kg) and 100 g/kg (90～112 g/kg), respectively. No marked pathological change of the organs was found. Conclusion According to the standard of grading of acute toxicity, THH solution belongs to the moderate class. Therefore, it is safe in clinical practice and has a wide application.

Objective To investigate the efficacy of postoperative concurrent chemoradiotherapy for early-stage cervical adenosquamous carcinoma and adenocarcinoma.Methods A total of 62 patients with cervical adenosquamous carcinoma,149 patients with cervical adenocarcinoma,and 2687 patients with cervical squamous cell carcinoma,all of whom were in stage Ⅰ B-Ⅱ A and were treated from 2006 to 2012,were enrolled,and some of them received postoperative pelvic radiotherapy ± para-aortic extended field radiation ±afterloading radiotherapy.The chemotherapy regimen consisting of DDP,TP,and FP was given to these patients.The chi-square test was used for comparison of general clinical data,the Kaplan-Meier method was used for calculating survival rates,and the log-rank test was used for survival difference analysis.Results Cervical adenosquamous carcinoma and adenocarcinoma had no significant differences in clinicopathological features (P=0.107-0.639).The high-risk patients with adenocarcinoma had a higher recurrence rate than their low-risk counterparts even after adjuvant radiotherapy or chemoradiotherapy (P=0.000).In the patients treated with surgery and radiotherapy,those with adenosquamous carcinoma had the shortest median survival time,followed by those with adenocarcinoma and squamous cell carcinoma (P =0.134,0.787);in the patients treated with surgery and concurrent chemoradiotherapy,those with adenocarcinoma had the shortest median survival time,followed by those with adenosquamous carcinoma and squamous cell carcinoma (P=0.131,0.643),and the median survival time showed a significant difference between the patients with adenocarcinoma and those with squamous cell carcinoma (P =0.000).In the patients with adenosquamous carcinoma and adenocarcinoma,the patients treated with postoperative concurrent chemoradiotherapy had higher incidence rates of short-term adverse reactions than those treated with postoperative radiotherapy (P=0.037,0.003),but the incidence rates of long-term adverse reactions showed no difference between the two groups of patients (P=0.861,0.655).In the patients with adenosquamous carcinoma,the patients treated with postoperative concurrent chemoradiotherapy had a lower rate of distant metastasis (P =0.003) and prolonged median overall survival and disease-free survival (both increased by 17 months) (P=0.811,0.799),as compared with those treated with postoperative radiotherapy,while in the patients with adenocarcinoma,the median overall survival and disease-free survival were reduced by 11 and 9 months,respectively (P=0.330,0.115).Conclusions Compared with postoperative radiotherapy,postoperative concurrent chemoradiotherapy for early-stage high-risk cervical adenosquamous carcinoma can reduce the rate of distance metastasis.Compared with radiotherapy,postoperative concurrent chemoradiotherapy for adenosquamous carcinoma and adenocarcinoma cannot improve survival time.

BACKGROUND:Stem cels from the apical papila are a new kind of mesenchymal stem cels, and whether it can
be used in root regeneration is the key to the present study. OBJECTIVE:To culture rat stem cels from the apical papila and periodontal ligament stem celsin vitro, and to compare the biology behaviors of these two kinds of cels, thereby providing experimental basis for the application of stem cels from the apical papila in root regeneration. METHODS:The apical papila, as wel as the periodontal ligament tissues from the healthy mandibular teeth of young rats were digested and cultured. Immunophenotypes of stem cels from the apical papila and periodontal ligament stem cels were detected by immunofluorescence technique. Then, cel growth curves were determined by MTT method and mineralized nodule formation was observed by alizarin red staining. RESULTS AND CONCLUSION:Stem cels from the apical papila and periodontal ligament stem cels were both positive for STRO-1. Stem cels from the apical papila were positive for CD90 and weakly positive for CD146. Periodontal ligament stem cels were positive for CD146 and weakly positive for CD90. The absorbance values of stem cels from the apical papila and periodontal ligament stem cels increased with the increasing of time and became stable at 8 days. Since the 4th day, the proliferation capacity of stem cels from the apical papila was significantly stronger than that of periodontal ligament stem cels (P < 0.05). Both of stem cels are visible to have mineralized nodule formation. Compared with the periodontal ligament stem cels, stem cels from the apical papila were stained obviously deeper and had more mineralized nodules. These results show that stem cels from the apical papila have stronger proliferation capacity and mineralization ability than periodontal ligament stem cels.

? AIM: To investigate health - related quality of life ( HRQOL ) state in children with intermittent exotropia using the Intermittent Exotropia Questionnaire ( IXTQ ) and research the effect of strabismus surgeries on HRQOL.?METHODS: In this prospective study, we chose 42 patients with intermittent exotropia ( aged 5-17 years) as case group, and 42 patients ( aged 5-17 years) as control group. The Chinese IXTQ was used to evaluate HRQOL at 1d preoperatively and 3mo postoperatively in the two groups, and the differences of the two groups before and after surgery and the effect of strabismus surgery on HRQOL were analyzed.?RESULTS:The scores of HRQOL in control group were statistically significant higher than that of case group ( P<0. 01 ). Every items showed a statistically significant difference except on “Kids tease me because of my eyes”and “ My eyes make it hard for me to make friends” ( P<0.05). At 3mo postoperatively ,the scores of HRQOL in case group significantly increased than that at 1d preoperatively(P<0. 01). Child IXTQ of case group was lower on every items than those of control group after surgery(P<0. 05).?CONCLUSION:Intermittent exotropia could affect the HRQOL in psychosocial and visual functional. The greatest HRQOL concerns for children with intermittent exotropia were shutting one eye when sunny, waiting for their eyes to clear up instead of taunts and friendship. The surgical treatment could improve HRQOL in children with intermittent exotropia.
