OBJECTIVE:To compare the therapeutic effects and cost-effectiveness among 3 therapeutic regimens. METHODS:85 cases with sudden deafness were divided into 3 groups:Group A (n=30) were ascribed to receive buflomedil, Group B (n=28) to receive compound Danshen and Group C (n=27) to receive Herba Erigerontis. The curative effects of the 3 were observed and the cost-effectiveness of which were analyzed. RESULTS:The costs of the 3(A, B and C) were 1 908.20yuan, 1 102.68yuan and 1 825.64yuan, respectively. The effective rates of the 3 were 93.33%, 60.71% and 70.37%, respectively. The cost-effectiveness ratios were 20.45yuan, 18.16yuan and 25.94yuan, respectively. As compared with Group B, the incremental costs for Group A and C were 24.73yuan and 74.84yuan, respectively with every one-unit effectiveness increase. CONCLUSION:Group C is the superior one among the 3 therapeutic regimens.

Objiective:To investigate the relationship between matrix metalloproteinases-2(MMP-2) and atrial fibrillation,also to investigate the relationship between MMP-2,cardiac function and left atria diameter of patients with atrial fibrillation.Methods:49 patients with persistent atrial fibrillation were included in the atrial fibrillation groups,and 47 patients with sinus rhythm were selected in the control group,the serum concentration of MMP-2 and TIMP-2 were measured with ELISA.The size of left atria diameter were detected with Doppler Ultrasonic cardiogram.Results:(1) The level of MMP-2 in atrial fibrillation group was significantly higher than that in control group(P0.05).(2) The size of left atria diameter in atrial fibrillation group was significant higher than that in the control group(P

The application of evidence-based medicine in bibliotherapy is defined as evidence-based bibliothera-py.After a description of the connotation, role and significance of bibliotherapy, and foreign and domestic studies on it, the problems in domestic bibliotherapy were pointed out with measures put forward for their solution, and the implementation of bibliotherapy was normalized in view of its methodology.

OBJECTIVE:To observe the clinical efficacy of misoprostol in the prevention of postcesarean hemorrhage(PCH).METHODS:344pregnant women with indications of cesarean section were randomly divided into3groups:group A were receive200mg of misoprostol sublingually,and group B to receive oxytocin by IV drop and myometrium injection with group C as control(no any drug was given)right after childbirth.PCH at different time were observed.RESULTS:Compared with group C,both the amounts and the incidences of PCH in group A and B were significantly lower(P

Objective Through oral vaccination activity on polio,the epidemiological and virological surveillance of acute flaccid paralysis (AFP) case finds its way to develop, so that the realization of eradication on polio may be verified.Method Various kinds of immunization activities such as regular basic immunization, booster vaccination, intensified vaccination and mopping-up operation were adopted among children of the right age in the whole province. Zero case report and active surveillance on AFP were carried out to those population under 15 who had had consultation in medical unit above county level. Each reported case or found case was treated by individual case investigation, follow-up study and sample collection. All the samples were virus-isolated ad identified by RD, Hep-2 and L20B cells. Result Since 1991, an AFP case surveillance system has been built up. Up to the end of 2000, a total of 1,749 AFP cases had been reported in hunan province, from which 1,404 cases samples were collected, and another 218 cases samples of contacts were also collected. A sum of 7 polio wild virus strains was examined out. Since July 1993, no wild strain has been found (isolated). Conclusion Hunan Province has successfully intervened in the circus (spread) of polio wild virus, and hence realized the goal of polio eradication.

The left to right shunt rate(F)and the transverse seetional area of ductus arteriosus(A)were calculated by color Doppler flow convergence method in 20 patients with patent ductus arteriosus.The results indicated that the shunt rate(F)was correlated fairly with Qp-Qs,Qp/Qs(measured by pulsed wave Doppler),the pressure gradient(△P)and the diameter of left ventricle(DLV)(r=0.81,0.62,0.69 and 0.53;P＜0.001,0.005,0.001 and 0.01,respectively).The transverse sectional area of ductus arteriosus(A)was also correlated closely with the diameter of ductus arteriosus(Dd)measured directly in two-dimensional view(r=0.81,P＜0.001).The F value of group Qp/Qs≥2:1 was apparently higher than that of group Qp/Qs＜2:1(P＜0.005).The color Doppler flow convergence method can rapidly and exactly evaluate the left to right shunt severity of patent ductus arteriosus.

High frequency key words in papers on MOOC were retrieved from CNKI and Wanfang Data Knowledge Service Platform.A co-words matrix was constructed , which was then transformed into correlation matrix and dis-similarity matrix, respectively.The correlation matrix was analyzed by multidimensional scaling analysis to show the hotspots in domestic MOOC studies on teaching reform, open education, information technology, resource develop-ment, library service innovation and its development trends.

Objective To evaluate the significance of suPAR,SCC-Ag in plasma and HPV16,18 in cervical secretion for monitoring pathogenetic condition and prognosis in patients with cervical cancer.Methods 206 cervical cancer patients blood and cervical secretion were collected.Plasma level of suPAR and SCC-Ag were measured by enzyme linked immunosorbent assay (ELISA) in health women and patients with cervical cancer.The expression of HPV16,18 of cervical secretion in control group and patients with cervical cancer were detected by fluorescence quantitative PCR.The correlations of the three indexes were analyzed.Results The plasma level of suPAR and SCC-Ag,the expression of HPV16,18 of cervical secretion in cervical cancer patients were obviously higher than those in health controls with statistical significance ((1.072 5±0.305 2) ng/ml vs (0.501 7±0.179 3) ng/ml,(0.980 6±0.162 7) μg/ml vs (0.261 4± 0.006 3) μg/ml and 53.89 ％ (90/167),46.15 ％ (18/39) vs 6.67 ％ (4/60),P ＜ 0.05).There was a positive correlation between plasma suPAR level and SCC-Ag level in invasive carcinoma of cervix patients (r =0.564,P ＜ 0.05).The plasma level of suPAR between in HPV16,18 positive group and in HPV16,18 negative group did not show difference (P ＞ 0.05).Conclusions In invasive carcinoma of cervix patients,there is a positive correlation between plasma suPAR level and SCC-Ag level.But it's not yet to conclude that plasma suPAR level of cervix invasive carcinoma patients is related to infection of HPV16,18.

Purpose:To study the expression of Survivin,P21 WAF1/CIP1 and CyclinD1 proteins in cervical carcinoma and to investigate their relation to recurrence of early stage cervical cancer of the uterus.Methods:Using streptavidin-biotin peroxidase (sp) method,we examined the protein expression of Survivin, P21 WAF1/CIP1 and Cyclin D1 in 55 cervical carcinomas (45 cervical squamous carcinomas and 10 cervical adenocarcinomas ) and 10 normal cervical tissues.Results:① The positive rates of Survivin,Cyclin D1,P21 WAF1/CIP1 were 0,10.0%,20.0% in normal cervical tissue,and 68.9%,51.1%,57,8% in cervical squamous carcinomas,and 60.0%,90.0%,80.0% in cerrical adenocarcinomas respectively. There were significant differences in the positive results of Survivin,CyclinD1,P21 WAF1/CIP1 between normal cervical tissue and cervical cancer ( P 0.05).③The coexpression of Survivin with P21 WAF1/CIP1 or CyclinD1 were both associated with higher tumor grade( P

Objective To study expression of extracellular signal-regualated kinase in intraepithelial neoplasia,prostatic cancer and BPH tissue. Methods Expression of extracellular signal-regualated kinase (ERK) was determined in 12 prostatic intraepithelial neoplasia (PIN),11 prostate cancer and 16 benign prostatic hyperplasia specimens.ERK expression was determined by immunohistochemistry. Results ERK expression was positive in all the 12 PIN specimens,6 of which being overexpressed.In the 11 prostate cancer specimens,overexpression was observed in only one while the other 10 under expressed.Overexpreassion was not observed in all the BPH specimens whereas 12 of the 16 showed underexpression. Conclusions ERK expression is obviously higher in PIN tissue (P
