Objective To explore the clinical value of real-time three-dimensional echocardiography (RT-3DE) in percutaneous transcatheter closure treatment of atrial septal defect (ASD). Methods The sizes,shapes and sites of ASD were visualized by RT-3DE and measured by full volume rendered three-dimensional echocardiography (3DE) before operation and after closure operation in 11 ASD patients,and compared with those from two-dimensional echocardiography(2DE) and the operation. Results Before the operation,RT-3DE visualization showed that the secundum ASD′s sites of the 11 patients were central and shapes were mostly ellipse. In this study a significant difference was found in the measurements of long distances of ASD between 3DE and 2DE [( 28.9 ? 8.2 )mm vs ( 20.0 ? 7.3 )mm,P 0.05 ]. Maximal diameters of defects measured by 2DE[( 21.1 ? 3.5 )mm,P

Objective To establish a novel method for rapid identification and drug resistance of Moraxella catarrhalis, Different sourses of blood and the formula of chocklate agars were detected the Growth Index(GI). Methods Moraxella catarrhalis from specimens contaminated by microbial flora were isolated with a choclate agar with 50 mg/L vancomycin (CHOC-V) method. Nine media were inoculated,on which GI were calculated and compared. beta-Lactamase were determined by nitrocefin slip method. Results 228 strains of Moraxella catarrhalis and 203 strains of recent limbus bacteria were examined. The sensitivity of this method was 100%,and the specificity was 100%. The GI of Moraxella catarrhalis on chocklate agars and blood agars was higher than that of the BCA, NUA, MHA ( P

Polyethersulfone hollow fiber membranes were prepared from polyethersulfone/N, N-Dimethylacctamide/poly (N-vinyl-2-pyrrolidinone) systems by dry/wet phase inversion process using water as coagulation bath. The effects of coagulation bath temperature and air gap distance on the surface structure, cross section structure and water flux of membranes were discussed. As increasing the temperature of coagulation bath and the air gap distance, the size of the pores at the surface effectively increased, while the finger-like structure under the outer surface changed to a sponge-like structure.

OBJECTIVE:To probe into the status quo,characteristics and influencing factors of ADR cases in our city. METHODS:In the retrospective statistical analysis study,a total of 752 ADR cases reported in Panzhihua Municipal ADR Monitoring Center in 2008 were analyzed and evaluated in respect of patients' age and sex,route of administration,drug varieties,organs and system involved and common countermeasures for ADR,etc. RESULTS:Of the total 752 ADR cases,323 cases of patients aged more than 60 showed the highest proportion(42.95%); 401 cases(53.32%) were caused by intravenous route; 810 kinds of drugs were used,of which antibiotics caused ADR in 317 cases (39.14%); lesions of skin and its appendants were the most common presentations of the ADR,which appeared in 314 cases(36.38%). CONCLUSION:The incidence of ADR relates to the patients' age,routed of administration and frequency of clinical drug use,which should be emphasized in the clinic.

Objective To investigate the effect of one-time anti reflux multi-function drainage bag in clinical application.Methods A total of 125 cases of benign prostate hyperplasis (BPH) were treated with transurethral resection of prostate (TURP) from October 2012 to March 2013 at our hospital of uropoiesis surgical department.All the cases were randomly divided into the control group (63 cases) and the experimental group(62 cases).The three cavities balloon catheter was connected with common drainage bag in the control group,and with one-time anti-reflux multi-function drainage bag in the experimental group.The urine in catheters and drainage bag of 3,5,7 days postoperatively in two groups was sampled for urine culture.The cases of daily urine tube plugging and daily drainage bag reflux in two groups were observed respectively.Results The cases of bacilluria significantly reduced in catheters of the experimental group compared with the control group and the drainage bag of the experimental group,respectively.The cases of bacilluria was significantly reduced in drainage bag compared with the control group.The cases of drainage bag reflux was significantly reduced compared with the control group.The cases of bacilluria in catheter and drainage bag had no significant difference in the control group.The cases of catheter plugging had no significant difference between two groups.Conclusions One-time anti reflux multi-function urine drainage bag can effectively prevent bacteria and reflux,and make the drainage system in a closed state.It has obvious advantage to prevent the happening of the retrograde infection compared with the common drainage bag.

OBJECTIVE:To explore the relationship between several common traits-identify characteristics of decoction pieces and laboratory test results,and improve the efficiency and accuracy of line inspection work. METHODS:Combined with the Chi-nese Pharmacopoeia(2010 edition)standards and traditional inspection experience,and collected decoction pieces,the accuracy of traits-identification points were inferred and increased by the ways of TLC,contents,aggravated powder,sulfur dioxide residues , staining and extract. RESULTS:The majority of decoction pieces had the relationship between character identification points and laboratory test results and a small part didn’t. CONCLUSIONS:This study has cleared the identification accuracy of several com-mon decoction pieces,and other parts of the differential diagnosis needs further exploration.

Objective Toinvestigatetheeffectofrehabilitationrobothandontheupperlimbmotor functioninpatientswithstrokeandhemiplegia.Methods Theeffectsoftraditionalrehabilitation therapy or robot rehabilitation treatment of 15 stroke patients with hemiplegia were analyzed retrospectively. There were 4 females and 11 males. According to the group order,they were divided into either a robot rehabilitation group (n=8 )or a general rehabilitation group (n =7 ). The patients of the general rehabilitation group received general rehabilitation training at the Department of Rehabilitation Medicine for 4 weeks,3 times a week,and 30 min for each time. At the same time,they also conducted family rehabilitation training,5 times a week,once for 1 h;the patients of the robot rehabilitation group received the general rehabilitation training for the same length of time as the general rehabilitation group,and they also performed robot rehabilitation training,5 times a week,once for 1 h. The patients of both groups were evaluated with the modified Ashworth scale (MAS )scores,Fugl-Meyer motor assessment of the upper extremity(FMA-UE),andWolfmotorfunctiontest(WMFT)beforeandaftertreatment.Results Compared with before training,the MAS score of the robot rehabilitation group was decreased significantly after four weeks of training. The time in WMFT was shortened significantly and the function score was improved obviously. The scores of upper extremity,hand score,and total FMA score in FMA-UE were improved significantly,and there were significant differences (all P <0. 05 ),while there were no significant differences in various indicators in the general rehabilitation group (all P>0. 05). Comparing the effects after four weeks of rehabilitation in both groups,the robot rehabilitation group was superior to the general rehabilitationgroupforthehandscoreinFMA-UE(allP<0.05).Conclusion Therehabilitation robot hand effectively lowered the upper limb spasticity. It has significant effect for recovery motor function of hand;however,it did not have a significant effect for motor rehabilitation on wrist.

OBJECTIVETo study the effect of different delivery modes on immunoprophylaxis efficacy so as to clarify whether or not cesarean section reduces immunoprophylaxis failure.

METHODSMothers with positive hepatitis B surface antigen (HBsAg) were selected in the third trimester of pregnancy. Their babies were inoculated with hepatitis B immunoglobulin at birth and hepatitis B vaccine at 1, 2 and 7 months of age. HBsAg and its antibodies (anti-HBs) were tested at 1, 4, 7, and 12 months of age, then followed up yearly.

RESULTSA total of 301 babies entered the study, including 144 born by normal spontaneous vaginal delivery, 40 by obstetric forceps or vacuum extraction, and 117 by cesarean section. The incidence of mother's HBeAg positivity or baby's gender constitution was comparable between the three groups. There were no significant differences in the positive rate of anti-HBs or HBsAg at follow-up periods among the three groups. At 12 months of age, anti-HBs could be detected in 78.9% of the babies born by normal vaginal delivery, 84.6% of the babies by forceps or vacuum extraction, and 86.4% of the babies by cesarean section. The positive rate of HBsAg was 8.1%, 7.7%, 9.7%, and chronic HBV infection incidence was 7.3%, 7.7%, 6.8% respectively.

CONCLUSIONSThere are no significant effects of delivery mode on the interruption of HBV maternal-baby transmission by immunoprophylaxis. Cesarean section does not reduce the incidence of immunoprophylaxis failure.
