OBJECTIVE:To evaluate the quality of anticoagulant therapy in patients who took warfarin and provide data sup-porting for strengthening the management of these patients. METHODS:A retrospective analysis of related clinical data of 214 pa-tients who meet the inclusion criteria was performed. RESULTS:The average time for patients took warfarin was (321.64 ± 189.50)d,average times for tested INR was(12.01±7.03)times in clinic;when anticoagulant therapy,INR<2.0 accounted for 51.96%,2.0≤INR≤3.0 accounted for 39.13%,and INR>3.0 accounted for 8.91%;patients with target INR≤2.0 accounted for 45.33%,target INR=2.5 accounted for 38.32%,and target INR≥3.0 accounted for 0.93%;the average TTR was (50.80 ± 22.32)%;and there was no statistical significance in the TTR of different ages and diseases(P>0.05). CONCLUSIONS:The anti-coagulant therapy in some patients who took warfarin shows poor quality,it needs strengthening the quality management to make it safe and effective.

The validity and reasonableness of emotional data are the key issues in the cognitive affective computing research. Effects of the emotion recognition are decided by the quality of selected data directly. Therefore, it is an important part of affective computing research to build affective computing database with good performance, so that it is the hot spot of research in this field. In this paper, the performance of two classical cognitive affective computing databases, the Massachusetts Institute of Technology (MIT) cognitive affective computing database and Germany Augsburg University emotion recognition database were compared, their data structure and data types were compared respectively, and emotional recognition effect based on the data were studied comparatively. The results indicated that the analysis based on the physical parameters could get the effective emotional recognition, and would be a feasible method of pressure emotional evaluation. Because of the lack of stress emotional evaluation data based on the physiological parameters domestically, there is not a public stress emotional database. We hereby built a dataset for the stress evaluation towards the high stress group in colleges, candidates of postgraduates of Ph. D and master as the subjects. We then acquired their physiological parameters, and performed the pressure analysis based on this database. The results indicated that this dataset had a certain reference value for the stress evaluation, and we hope this research can provide a reference and support for emotion evaluation and analysis.

Objective To explore the effect of the simvastatin administration on the expression of connective tissue growth factor （CTGF） in fihrotic lungs of rats. Methods The cats were treated with single intratracheal instillation of bleomycin （BLM） or instillation of the same volume of normal saline （NS） as a control. The administration of simvastatin（20 mg/kg）began once a day immediately or 7 days later after intratracheal BLM instillation respectively with the same volume of NS was given as a vehicle control. The rats were killed on day 7,14 and 28 respectively. Pathological alteration of lung tissue was observed hy HE staining and Masson staining. Hydroxyproline（HYP）content in lung tissue was used to determine the severity of pulmonary fibrosis. The expression of CTGF in lung tissue was exanfined by immunohistochem- istry staining and photodeusitometry. Results Histopathological changes of pulmonary fibrosis emerged gradually after the instillation of BLM. The expression level of CTGF was increased in lungs of rats after intratracheal instillation of BLM, compared with the control. The administration of simvastatin immediately or 7 days after intratracheal instillation of BLM, attenuated the histopathological changes of bleomycin- induced puhnonary fibrosis and prevented the increased expression of CTGF in lung tissue on day 28. Conclusion The adntinistration of simvastatin, immediately or 7 days after intratracheal BLM instillation, prevented the up-regulation of CTGF in fibrotic lungs of rats, which ntight be one of the mechanisms of the anti-fihrosis of simvastatin in lungs.

Objective To explore the clinical efficacy of continuous intravenous pump of Shengmai injection for treatment of patients with acute coronary syndrome(ACS)combined with cardiogenic shock. Methods In the period from January 2005 to March 2011,33 hospitalized patients with ACS complicated by cardiogenic shock were selected in the treatment group,and in the same period,32 in-patients with ACS were enrolled in the control group, According to traditional Chinese medicine(TCM)syndrome type,the treatment group was subdivided into Yin xutype(Yin deficiency,15 cases),Qi xu type(Qi deficiency,11 cases),Xue yu type(blood stasis,7 cases). Conventional western medicine treatment was given to the two groups,besides,Shengmai injection in 30-60 mL intravenous drip,once a day was applied in the control group,while in the treatment group,Shengmai injection in 10-100 mL/h trace pump continuous intravenous infusion was given,after the blood pressure returned to normal,the infusion was changed to 5 mL/h trace pump continuous intravenous injection for consecutive 5-7 days. After treatment, the changes of clinical efficacy,blood pressure,heart rate ,improvement of clinical symptoms were observed in two groups,and the changes of mean arterial pressure(MAP)in cases with different syndromes in treatment group were also investigated. Results The rates of the significant therapeutic effect and total effect in the treatment group were obviously higher than those in the control group〔significant effect:69.7%(23 cases)vs. 46.9%(15 cases);the total efficacy:90.9%(30 cases)vs. 62.5%(20 cases),both P<0.05〕. The comparisons of blood pressure and heart rate before and after treatment in the two groups were not significant(all P>0.05). After 48 hours of treatment in the two groups,the clinical symptoms were all improved〔chest pain:2 cases(6.1%)vs. 10 cases(31.3%),sweating:3 cases(9.1%)vs. 13 cases(40.6%),shortness of breath:4 cases(12.1%)vs. 12 cases(37.5%),all P<0.05;heart palpitations:5 cases(15.2%)vs. 9 cases(28.1%),nausea:3 cases(9.1%)vs. 4 cases(12.5%),both P>0.05〕. In treatment group,the increase of MAP in patients withYin xutype(mm Hg,1 mm Hg=0.133 kPa)was higher than that in patients with Qi xu type and Xue xu type(105.00±8.53 vs. 91.00±9.53,89.00±3.53,both P<0.05). Conclusion Continuous intravenous injection of Shengmai injection has significant therapeutic effect for treatment of patients with ACS combined with cardiogenic shock.

Background Central retinal vein occlusion (CRVO) is a common retinal vascular disease.Intravitreal injection of ranibizumab, a vascular endothelial growth factor (VEGF) antibody, is being a useful approach to the treatment of macular edema secondary to CRVO.However,little literature about choroidal thickness variations following intravitreal injection of ranibizumab for CRVO is published up to now.Objective This study was to observe the dynamic changes of macular choroidal thickness after intravitreal injection of ranibizumab in CRVO eyes.Methods A self-controlled series cases study was designed.Thirty-one eyes of 31 CRVO patients were included in Tianjin Eye Hospital from June 2013 to November 2014,with the males 19 and females 12 and mean age of (51.13±16.65) years.Ranibizumab (5 mg,5 ml) was intravitreally injected in the CRVO eyes once per month for 3 times by the same operator.A enhanced depth image (EDI) mode of spectral-domain OCT system was employed to measure the choroidal thickness at subfoveal, 1 mm from fovea nasal and 1 mm from fovea temporal before and 1 month,2,3 months after first injection in both CRVO eyes and contralateral healthy eyes, respectively.The best LogMAR vision was recored.This research protocol was approved by the Ethic Committee of this hospital, and written informed consent was obtained from each individual prior to any medical examination.Results Retinal bleeding was exhibited in the CRVO eyes in color photography,and fundus fluorescein angiography showed the fluorescine leakege in the early phase and fluorescine accummulation in the late phase.The mean choroidal theckness value was (325.32±83.04) , (294.83±80.61), (315.95±90.77) and (314.81±84.98) μm before injection and 1,2,3 months after injection,respectively,showing a significantly difference among various time points (F =7.96,P =0.00) , and the choroidal theckness values were evidently reduced in various time points after injection in comparison with before injection (P =0.01,0.01,0.00).The choroidal thickness value at foveal was (314.81±84.98) μm in the CRVO eyes 3 months after injection,and that in the fellow eyes was (260.47±55.90) ,with significant difference between them (t =2.95, P =0.01).The LogMAR vision was 0.17±0.09,0.37±0.23,0.42±0.26 and 0.49±0.21 before and 1,2,3 months after injection,with the significant difference among various time points (F =21.50, P =0.00) and showed considerable improvement after intravitreal injection of ranibizumab(all at P＜0.01).The mean retinal thickness value was (244.14-±23.28) μm in the fellow eyes, and those in 1 month, 2,3 months after injection were (523.81 ± 147.61), (352.13 ± 166.71),(376.39±209.46) and (369.00±225.61) μm in the CRVO eyes, showing obvious reduce after intravitreal injection, with significant difference among different time points (F =7.09, P＜0.01).Conclusions Choroidal thickness at macular fovea is obviously increased in CRVO eyes compared with the contralateral healthy eyes.Intravitreal injection of ranibizumab can reduce choroidal thickness and therefore improve vision.EDI OCT is available in the evaluation of dynamic change of choroidal thickness.Macular choroidal thickness could be used as a predictor of CRVO prognosis following intravitreal ranibizumab.
