Objective To investigate the value of quantitative TB‐DNA test ,interferon gamma release test and the detection of tuberculosis antibodies for the diagnosis of active pulmonary tuberculosis .Methods 51 patients were diagnosed as tuberculosis from 2013 July to 2014 June in the hospital ,whose sputum smear microscopy for acid fast bacilli were positive .Then TB‐DNA quantitative test ,interferon gamma release test (T‐SPOT .TB)and tuberculosis antibody detection were performed for those pa‐tients .All the result were retrospectively analysed .Results The positive rate of T‐SPOT .TB was 90 .1% ,the positive rate of quan‐titative TB‐DNA test was 74 .5% and the positive rate of tuberculosis antibody detection was 37 .3% .Conclusion Because the re‐sult of T‐SPOT .TB is not affected by the process of specimen collection ,it is the most sensitive test of the three tests at present , and has higher value in the auxiliary diagnosis of active pulmonary tuberculosis than the other two .

OBJECTIVE: To investigate the use of psychotropic substances for outpatients in our hospital.METHODS: The psychiatric substances used in the outpatients between June and December in 2006 were analyzed statistically in respect of the defined daily dose,DDDs and average daily expense etc.RESULTS: Of the total 7 286 prescriptions analyzed,the psychotropic substances prescribed totaled 12 kinds,of which,2 were typeⅠ,and 10 type Ⅱ.Estazolam,Alprazolam and Diazepam ranked at the first three places in terms of numbers of prescriptions;Estazolam,Alprazolam and Clonazepam ranked at the first three places in terms of DDDs;Zolpidem,Midazolam and Alprazolam ranked at the first three places in terms of consumption sum;Nitrazepam,Estazolam and Phenobarbital ranked at the lowest places in terms of average daily expense.CONCLUSION: Of the total psychiatric substances consumed in the outpatients of our hospital,benzodiazepines were used predominantly for their merits of low cost but proved efficacy.

Objective To explore post-operative treatment and intensive care of infants with congenital heart disease(CHD).Methods Clinical data of post-operative treatment and intensive care in 264 infants with CHD were analyzed retrospectively from May.1998 to Apr.2006.Among them,256 cases underwent radical operation,and 8 cases with palliative operation.Results Sixteen cases died early.Among them,after operation,there were 8 cases with Fallot′s syndrome,2 cases with complete atrioventricular canal anomalous,3 cases with ventricular septal defect(VSD)and pulmonary hypoplasia(PH),1 case with tricuspid atresia,1 case with single ventricle,and 1 case with persistent truncus arteriosus.Causes of death include low cardiac output,acute renal failure,degree of Ⅲ atrioventricular block(AVB),lung infection,respiratory failure and arrhythmia.One case with complete pulmonary vein ectopia was discharged due to post-opertative refractory hypercapnia;1 case with atrial septal defect(ASD)and patent ductus arteriosus(PDA) died of refractory heart failure due to high pulmonary arterial pressure 1 year after operation;1 case with tetralogy of Fallot died of lung hemorrhage after radical correct operation followed by palliative outflow tract deo-ppilant operation.Of them 245 cases alive,there were 233 cases with heart function grade Ⅰ,12 cases with grade Ⅱ.Conclusion Correct management of respiratory system,systemic electrocardial care,handling with arrhthymia on time,low cardiac output and nutritional support are the important measures in improving survival rate of infants with CHD.

ObjectiveTo explore the abilities of automatic processing,controlled processing,selective attention by Stroop color-word test in patients with ischemic cerebrovascular disease.Methods124 patients (aged 60-90 years) with ischemic cerebrovascular disease and 126 cases with age and civilization matched healthy people were examined by Stoop color-word test (SCWT).The SCWT indexes were compared between two groups.Results Reading time of card 1,timeconsuming and error of card 2,4 and Stroop interference effects (SIE) in SCWT had significantly decreased in the patients than in the healthy people (all P＜0.05).ConclusionsThe abilities of controlled processing and selective attention,but not automatic processing are damaged in patients with ischemic cerebrovascular disease.

Objective To investigate the effectivity of bispectral index(BIS)and auditory -evoked potentials index(AEP index)in monitoring the depth of desflurane anesthesia in the elderly. Methods Sixty patients(ASA gradeⅠ～Ⅱ)without obvious auditory and psychiatric dysfunction undergoing general anesthesia were enrolled in this study,and they were devided into the elderly group (n=30)and the non-elderly group(n=30)according to the age.After the endotracheal intubation,the lungs were ventilated with desflurane in oxygen.End-tidal concentrations of desflurane were maintained at 0.6,1.0 minimum alveolar concentrations(MAC)and 1.3 MAC for 20 minutes, respectively.The changes of BIS,AEP index,mean arterial blood pressure(MAP)and heart rate (HR)were recorded simultaneously.Results In the elderly and non-elderly groups,BIS were 94.14?6.5 and 94.5?4.6(P＞0.05),and AEP index at pre-anesthesia were 87.2?11.7 and 89.2?6.9(P＞0.05)respectively,which showed no statistic difference between two groups.BIS and AEP index decreased significantly in each time point at pre-anesthesia compared with those during anesthesia in two groups (P＜0.05).In the periods of increasing concentration of desflurane,BIS decreased gradually in two groups(P＞0.05),but BIS in the elderly group were higher than in the non-elderly group at the same end-tidal desflurane concentration(P＞0.05),and BIS negatively correlated with the end-tidal desflurane concentration in two groups.In the elderly group,AEP index decreased significantly at the concentration of 1.0 MAC and 1.3 MAC of desflurane compared with that of 0.6 MAC(P＜0.05),but there was no difference in AEP index with increasing end-tidal desflurane concentration from 1.0 MAC to 1.3 MAC(P＞0.05).At every concentration of desflurane,AEPindexintheelderlygroupwaslessthaninthenon-elderlygroup(P＜0.05).Conclusions BIS and AEP indexes correlate well with the end-tidal desflurane concentration,and are valuable for monitoring the depth of desflurane anesthesia in the elderly.AEP index can predict the difference in depth of anesthesia at the same end-tidal desflurane concentration between the elderly and the non-elderly.

Objective To explore the relationship between dynamic changes in ultra-micro-structural of pulmonary arteries and endogenous hydrogen sulfide in rats with left-right shunt.Methods Rats in shunt group were subjected to an abdominal aorta-inferior vena cava shunt to create an animal model of pulmonary artery structural remodeling. After 1 day, 3 days, 1 week, 4 weeks and 8 weeks of experiment, the ultra-micro-morphologic changes of pulmonary arteries of rats were observed under electronic microscope and H_2S concentration in serum was evaluated by modified sulfide electrode method.Results The changes of ultra-micro-structure of pulmonary arteries were progressively exacerbated, endothelial cells became swollen and large in size on 3 days, smooth muscular cells increased in size as well as the change of endothelial cells in 1 week, and they changed from contractile phenotype to synthetic phenotype in 4 weeks.Conclusions Shunt exhibited changes of ultra-micro-structure of pulmonary arteries are accompanied by the changes of endogenous H_2S. It is suggested that endogenous H_2S might play a protective role in changes of ultra-micro-structure of pulmonary artery.

Objective: To study the effect of the sharp marginal ridge of the abutment on the casting of the fit metal full crown in dental preparation.Methods: We established the models of the designed crown-based-teeth(American Dental Association style,No2 trail) with a sharp or smooth marginal ridge,and cast a metal crown for each model.We injected silicone into the crown and immediately fixed it onto each model.Then we took out the solidified silicone and measured its thickness between the crown and the occlusal face of each model.The thinner the thickness,the better the fitness.Results: The average silicone thickness was 250 ?m in the smooth marginal ridge group and 1 660 ?m in the sharp marginal ridge group,with significant difference in between(P
