Prostasomes are one of the subcellular structures secreted by prostatic epithelial cells.They present in human semen as membranous vesicles with average diameter of 150nm(40-500nm).440 proteins have been identified in human prostasomes and possess many physical functions.Prostasomes may not only exert a motility function for spermatozoa by delaying the acrosome reaction,but also have immune regulatory function,antibacterial and antioxidant characteristics.Prostasomes can be isolated from the serum and urine,and they present both in normal and prostatic cancer tissues.Prostasome can be a special prostatic biomarker and has a close association with prostatitis and prostate cancer.

Objective:To study clinical efficacy of one-visit versus two-visit root canal therapy for pulpitis, apical periodontitis and taintless teeth with nickel-titanium rotary instruments and ultrasonic irrigation unit. Methods: A total of 309 patients with 338 teeth were selected. The teeth were classified into pulpitis group, apical periodontitis group and taintless teeth group. Patients were randomly assigned to either the one-visit or two-visit root canal therapy, the treatment effects were evaluated with clinical trial and radiography after 3 days, 1 week, 1 month and 3 months. Results: The short-term outcome was changes in apical bone density by using the periapical index (PAI), long-term outcome exhibited equally improvement in clinical curative effect in both groups. Although one-visit root treatment could cause more intensive postoperative pain than that of two-visit endodontic treatment during 1-3 days, the indisposition could be eliminated by using medicine. Conclusion: By using of the nickel-titanium rotary instruments and canal ultrasonic irrigation unit, the cure rate of root canal therapy of one-visit and two-visit endodontic treatment has been improved, with no significant difference between two groups, so that one-visit root treatment can be used in clinic.

Objective To observe the efficacy and prognosis of aconite-cake-partitioned moxibustion plus acupuncture in treating peptic ulcer.Method Thirty-four patients in the treatment group were intervened by aconite-cake-partitioned moxibustion plus acupuncture, while thirty-three patients in the control group were by Omeprazole Enteric-coated Capsules. The clinical efficacy, the effect on ulcer under gastroscope and Hp, and the therapeutic efficacy 12 months after the intervention were evaluated.Result The total effective rate was 91.2% in the treatment group versus 72.7% in the control group, and the difference was statistically significant (P<0.05). For ulcer by gastroscopy, the total effective rate was 85.3% in the treatment group versus 69.7% in the control group, and the difference was statistically significant (P<0.05). After intervention, the Hp level didn’t show significant change (P>0.05). The relapse rate of the control group was higher than that of the treatment group 12 months after the intervention.Conclusion Aconite-cake-partitioned moxibustion plus acupuncture can produce a higher efficacy than Western medication in treating peptic ulcer.

tep immunochromatographic method accounted for 96.4%.Conclusion Both RT-PCR and step immuno chromatographic method can not be used as means of short-term therapeutic effect evaluation.

Objective To observe the therapeutic efficacy of acupuncture plus moxibustion in treating chemoradiotherapy-induced leukopenia in patients with malignant tumors.Method A total of 120 patients with malignant tumors who presentedleukopenia during receiving chemoradiotherapy were randomized into two groups. Sixty cases in the treatment group were intervened by acupuncture plus moxibustion; sixty cases in the control group were intervened by oral administration of Batilol tablets and Leucogen tablets.The peripheral white blood cell (WBC) count in the two groups was detected on treatment day 3, 7, 14, 21, and 28.The clinical efficacies of the two groups were compared.ResultThe WBC started toincreaseafter 1-week treatment in thetreatment group (P<0.05) and the increase was statistically significant after 2-week treatment (P<0.01); in the control group, the WBC started to increase after 2-week treatment (P<0.05)and the increase was statistically significant after 3-week treatment (P<0.01); the effect of increasing WBC was more significant in the treatment group compared to the control group (P<0.05,P<0.01).The total effective rate was 90.0% in the treatment group versus 53.3% in the control group, and the between-group difference was statistically significant (P<0.01).Conclusion Acupuncture plus moxibustion can produce a significant efficacy in treating leukopenia induced by chemoradiotherapy.

Objective To observe the clinical efficacy of acupuncture-moxibustion in treating endometriosis (EM). Method Fifty EM patients were randomized into two groups, 25 cases in each group. The treatment group was intervened by acupuncture-moxibustion, while the control group was intervened by oral administration of Mifepristone tablets. Abdominal pain, pelvic lump, and relevant indicators were observed before and after the treatment, and the therapeutic efficacies were compared.Result After 6-month treatment, symptoms including abdominal pain obviously subsided in the treatment group and the total effective rate was 92.0%, versus 52.0% in the control group, and the between-group difference was statistically significant (P<0.01). The pelvic lump size was significantly changed after the treatment in both groups (P<0.05), suggesting that the lump size became smaller in both groups after the treatment;there was a significant difference in comparing the pelvic lump size between the two groups after the treatment (P<0.05), indicating that the lump size was reduced more significantly in the acupuncture-moxibustion group. The level of serum CA125 changed significantly after the treatment in both groups (P<0.05), suggesting that serum CA125 dropped in both groups after the treatment; there was a significant difference in comparing the level of serum CA125 between the two groups after the treatment (P<0.05), indicating that serum CA125 dropped more significantly in the acupuncture-moxibustion group. A year later, there was a significant difference in comparing the relapse rate between the two groups (P<0.05), revealing that the relapse rate was significantly lower in the acupuncture-moxibustion group than in the medication group.Conclusion Acupuncture-moxibustion can produce a marked therapeutic efficacy in treating EM.

ObjectiveTo evaluate the marginal integrity of restoration in two types of mate- rials, or resin- modified glass ionomer cement and polyacid- modified composite resin (compomer). MethodsRestorations of four kinds of material (GC Fuji Ⅱ LC, VitremerTM, Dyract compomer and F2000 compomer) were placed in the facial Class V cavity preparations in forty noncarious human molar teeth. The teeth were randomly assigned to 4 experimental groups of 10 teeth each. After thermal cy- cling( × 20,5 ～55℃ ), the teeth were immersed in 1％ basic fuchsin dye for 24 hours at room tempera- ture. Staining along the teeth restoration interface was recorded. ResultsThe data indicated signifi- cant differences between all the restorative materials for both occlusal and gingival scores ( P=0.026, P = 0. 000)respectively. Further analysis revealed there were statistically significant differences between GC Fuji Ⅱ LC and others on occlusal margins versus Dyract compomer and others on gingival margins. Conclusion Factors such as dental conditioning, rates of water absorption and thermal coefficient were related to microleakage. Resin - modified glass ionomer cement showed less microleakage than polyacid- modified composite resin tested.

Objective To study the mechanism of the resistance in Acinetobacter baumannii to common antibiotics.Methods Bacterial susceptibility test to ?-lactamatic antibiotics,quinolones,aminogiycosids were done by the Kirby-Bauer method and agar dilution method for 35 isolates.Penicillin-beta-lactamase,AmpCs,Metallo-beta-lactamase,ESBLs were detected by iodine-starch test,3-dimension test,microbiology sensitivity synergic test,disc agar diffusion method respectively.Outer membrane protein was analyzed by SDS-PAGE.Accumulation of ciprofloxacin was determined by direct Fluorescence method.The gene of Tem-1,aac-4 and gyrA were amplified by PCR while the gyrA was sequenced.Results 28 isolates were multi-resistant to common antibiotics in 35 isolates.16 isolates produced Penicillinase,10 isolates produced Cephalosporinase,2 isolates produced metal-beta-lactamase,3 isolates produced ESBLs.The analysis of outer membrane proteins showed that a protein of 29kD disappeared and 26kD protein enhanced in resistant isolates.The accumulation of ciprofloxacin in resistant isolates decreased.After treatment with NaN_3,the drug uptake increased to the normal level.Most of [QX(Y8]Tem-1 gene were positive except 2 drug resistant and 3 sensitive isolates.All of [QX(Y8]aac-4 were negative while gyrA were positive.DNA sequencing analysis revealed there had point mutation in the gyrA gene.Conclusion Beta-lactamase,active drug efflux,outer membrane protein permeability decreasement and gene mutation were the factors contributing to the antibiotics resistance of Abaumannii.

Objective To compare the characteristics of MRI, CT, single photon emission computed tomography(SPECT) and transcranial Doppler sonography(TCD) in patients with spongiform leukoencephalopathy after inhaling heroin vapor. Methods Seventeen patients were investigated. MRI or CT was scanned in 17 patients, SPECT in 9 patients′ and TCD in 11 patients. Results MRI or CT: Brain MRI and CT revealed extensive symmetric white matter involvement of bilateral cerebral and cerebellar hemispheres and the brainstem.The lesions, which showed no contrast enhancement, were hypodense on CT and hypointense on T 1 weighted and hyperintense on T 2 weighted MRI. SPECT: The regional cerebral blood flows(rCBF) of white matter involvement on bilateral cerebral and cerebellar hemispheres was reduced obviously. The rCBF of temporal lobes, parietal lobes, occipital lobes, cerebellar hemispheres, and basal ganglion was reduced in varying degrees. TCD: The systolic peak became sharpened, and end diastolic flow velocity and mean flow velocity were reduced obviously and pulsatility index was increased markedly in patients with spongiform leukoencephalopathy after inhaling heroin vapor. Conclusion The characteristic manifestations of MRI and CT imaging may be regarded as the main foundation of diagnosing spongiform leukoencephalopathy after inhaling heroin vapor; SPECT and TCD can help comprehend the changes of hemodynamics of cerebral vessels and the degree of cerebral ischemia in patients with spongiform leukoencephalopathy after inhaling heroin vapor.
