Objective To evaluate objectively the traditional methods on the assessment of bladder outlet obstruction(BOO) due to BPH. Methods Correlation between the urodynamic findings and the traditional diagnostic parameters such as age,IPSS,Vp,Qmax z and PVRr was studied.The clinical prostatic score(CPS),derived from multiple regression of clinical parameters depending on URA,was evaluated. Results The parameters such as age,IPSS,Vp,Qmax z and PVRr were evaluated with reference to pressure flow study.Every parameter alone was not enough for BOO diagnosis. The regression equation was CPS=49.8-3.3 Qmax z+0.5 IPSS+0.2 Vp+7.5 PVRr.Correlation coefficient between CPS and urodynamic findings was 0.629 and was significantly higher than that of any clinical parameter alone.With CPS≥35,the sensitivity was 83.7% and specificity 85.8% for the diagnosis of BOO.With CPS

OBJECTIVE To investigate the ?-lactamase genes and virulence gene in Escherichia coli isolated from the old patients.METHODS Twenty strains of E. coli were selected to test 15 kinds of ?-lactamase genes (TEM,SHV,CTX-M-1 group,CTX-M-2 group,CTX-M-9 group,OXA-1 group,OXA-2 group,OXA-10 group,PER,GES,VEB/CEF,CARB,DHA,ACT/MIR and LAT/CMY) and two virulence genes (CNF-1 and CNF-2).RESULTS Six ?-lactamase genes and one virulence gene have been found out from these 20 strains of E. coli. The results showed that there were 14,3,1,5,2,2 and 1 strain which carried TEM,SHV,CTX-M-1 group,OXA-1 group,DHA,ACT/MIR and CNF-1,respectively. These 20 E. coli strains contained at least 1 ?-lactamase gene and 7 E. coli strains were found containing more than 2 kinds of ?-lactamase at the same time.CONCLUSIONS The resistance of these 20 E. coli strains to ?-lactam antibiotics is closely relative to ?-lactamase.

Objective To investigate the effects of 17?-estradiol (E2) on the gene expression of typeⅠA bone morphogenetic protein receptor (BMPR-ⅠA) and core-binding factor alpha 1 (Cbf?1) in rat bone marrow stromal cells exposed to the differentiation medium and to elucidate the effects of E2 on osteoblastogenesis. Methods Adherent bone marrow stromal cells were cultured in differentiation medium containing DEX (10 -7 mol/L), 1,25-(OH)2D3 (10 -9 mol/L) and different concentrations of E2. Effects of different concentrations of E2 on the gene expression of BMPR-ⅠA and Cbf?1 was quantified by RT-PCR based on the comparison with an internal reference, ?-actin expression, and identified by Northern blotting. Alkaline phosphatase (ALP) activity of cells was detected. Contents of type Ⅰ collagen were determined by Van Gieson staining. Results E2 could evidently inhibit the expression of BMPR-ⅠA and Cbf?1 mRNA during the differentiation process of bone marrow stromal cells into osteoblasts in a dose-dependent manner. These were confirmed by Northern blotting. The ALP activity increased in a concentration-dependent manner, but the amount of type Ⅰ collagen decreased in a concentration-dependent manner. Conclusion E2 can significantly inhibit the gene expression of BMPR-ⅠA and Cbf?1 in bone marrow stromal cells and inhibit osteoblastogenesis in vitro.

AIM:To investigate the effects of 17?-estradiol (E_2) on the gene expression of typeⅠA and typeⅠB bone morphogenetic protein receptor (BMPR-ⅠA,ⅠB) in rat bone marrow stromal cells exposured to the differentiation medium and to elucidate the effects of E_2 on osteoblastogenesis. METHODS: Adherent bone marrow stromal cells were cultured in differentiation medium containing DEX(10 -7 mol?L -1 ) and 1,25(OH)_2D_3 (10 -9 mol?L -1 ) and different concentrations of E_2. The gene expression of BMPR-ⅠA,ⅠB was quantified by semiquantitative RT-PCR. RESULTS: E_2 evidently inhibited the expression of BMPR-ⅠA mRNA in bone marrow stromal cells.The suppression was dose-dependent. When examined under various concentrations of E_2 (0-10 -6 mol?L -1 ),the expression of BMPR-ⅠA mRNA were decreased from (25.7?2.5)% to(16.3?1.5)%( P

Objective To observe the preventive effects of electroacupuncture therapy on glenohumeral subluxation(GHS)in patients of cerebral stroke of super-early period. Methods A total of 160 cases with cerebral stroke were randomly recruited into a control group of 80 cases and a treatment group of 80 cases. The control group was treated with conventional medicine and rehabilitation training, while the treatment group was given electro-acupuncture therapy based on conventional medicine and rehabilitation training. All treatments were performed once in each day, and one treatment course lasted for ten days. The preventive effect was evaluated after the successive three courses. Results 4 cases in treatment group and 2 cases in control group quitted in therapeutic process. The GHS incidence rate in the third course of treatment group was significantly lower than control group (P<0.05). The severe GHS incidence rate of treatment group was significantly lower than control group in the second course (P<0.05)and the third course (P<0.01). The GHS scale of the treatment group showed no significant difference in all three courses (P>0.05), while the control group showed significant difference in one course of all three(P<0.05). Conclusion Electro-acupuncture therapy can significantly decrease GHS incidence rate, relieve pathogenetic condition, control its progress, and so thus prevent GHS of stroke patients in super-early period.

Parkinson's disease (PD) is the second most common neurodegenerative disorder of the central nervous system, affecting 1 in 50 people over the age of 60 years. PD is the result of loss of a majority of dopamine (DA) neurons in the midbrain substantia nigra. The basic pathological feature of PD is the formation of intracytoplasmic eosinophilic inclusion bodies, Lewy bodies. So far, what leads to DA neuron degeneration is uncertain. Thirteen familial PD related loci have been identified, including six mutations:α-SYN(PARK1/4), Parkin(PARK2), UCHL1(PARK5), PINK1(PARK6), DJ-1(PARK7) and LRRK2 (PARK8). Drosophila has been widely used in the study of human diseases because of its genetic advantages. The Drosophila DA synthesis is similar to human, and Drosophila DA system is also involved in motion control, so it is generally considered that DA neuron death of Drosophila can be a perfect model of PD. In this article we review the progress of research methods based on Drosophila model in study of mechanisms related to Parkinson's disease.
