Objective　To evaluate the safety of biopsy of the prostate guided by transrectal ultrasound.Methods　Three hundred and seventeen patients suspected to have prostate cancer were examined and 208 patients were followed up.Results　One hundred and eighty-one patients followed up did not feel severe pain during the biopsy of the prostate. Clinical manifestations induded 12 cases of hematuria,4 dases of hematospermia,1 case of fever, 2 cases of pollakisuria and urodymia,2 cases of uroschesis,which disappeared after corresponding treatment.Conclusions　Biopsies of the prostate guided by transrectal ultrasound is advantageous in diagnosis of prostatic carcinoma.

Physiologically based pharmacokinetic (PBPK) modeling is established based on the information of existing human or other animal anatomy, knowledge of physiology and biochemical data. The model uses mathematical methods to simulate chemicals′process of absorption, distribution, metabolism and excretion in the body, in order to achieve the dose and interspecific extrapolation and to predict the chemical level in the specific organ at the specific time. In studies on toxicology of nanomaterials, the PBPK models in the silver nanoparticles, zinc oxide nanoparticles, titanium dioxide nanoparticles and polymer nanomaterials are gradually established. PBPK modeling can not only provide information on the dynamic change of nanomaterials in the body, but is of great significance for to quantitative evaluation of biological safety of nanomaterials. PBPK modeling will be a hot spot for research in the field of nanotoxicology.

Objective To investigate the effects of ultrarapid opiate detoxification during general anesthesia on the plasma morphine concentration and brain ?-endorphin content in rats addicted to morphine. Methods Ninety male Wistar rats aged 12-15 weeks weighing 180-220 g were randomized into 6 groups: group I normal animal ( n = 5); group II morphine addiction ( n = 5); group III natural withdrawal ( n = 20); group IV general anesthesia ( n = 20); group V general anesthesia + naloxone ( n = 20) and group VI clonidine pretreatment ( n = 20). Morphine addiction was induced by subcutaneous injection of increasing doses of morphine sulphate for 5 days (5, 10, 20, 40 and 50 mg? kg-1 t.i.d. ? 5 days) . Morphine detoxification was started on the 6th day. General anesthesia was induced and maintained with ?-OH and midazolam i.m. supplemented with intermittent isoflurane inhalation to maintain loss of righting reflex. Spontaneous breathing was kept during general anesthesia. In group V naloxone 0.05, 0.1 and 0.2 mg was injected subcutaneously at 5, 30 and 60 min after loss of righting reflex. Successful detoxification was defined as no withdrawal symptoms after subcutaneous injection of naloxone 0.1 mg. In group VI clonidine 0.05 mg ? kg-1 was given i. v. 1 hour before induction of anesthesia. Blood samples and brain tissue were obtained before detoxification in group I (normal animal) and II (morphine addiction) while in the other 4 groups they were obtained immediately and 1,2,3 day after detoxification.Results The plasma morphine concentration was 224 ? 164 ng?ml-1 in group II (morphine addiction), significantly higher than in all the detoxification groups ( P V ) (P

Objective: To investigate alteration and cross link of the aortic intima and platelet endogenous L-Arg/NOS/NO pathway induced by water immersion restraint (WIR) stress. Methods: After 7 h of WIR stress, the aortic intima was isolated and prepared the platelet, then NO_2- production released from aortic intima and platelet was measured with Greiss regent, NOS activity and L-arginine transport activity were detected by isotope tracer method. Results: After 7 h of WIR stress, the levels of NO_2- from platelet and aortic intima obviously decreased by 57% and 46% respectively as comparied with the control rats (P

Objective To understand information on cognitive and demand of chronic kidney disease(CKD) patient to contin‐uing nursing .Methods Adopting stratified random sampling method took samples 200 CKD patiens who were treated at kidney disease of internal of general hospital form March to June 2014 .Self‐made questionnaire was used to survey cognitive and demand of chronic kidney disease patient to continuing nursing .Results Totally 200 questionnaires were gave out and 184 of them were taken back ,efficient rate is 92% .First ,cognition :10 .32% CKD patiens knew the meaning of continuing nursing ,9 .24% CKD patiens knew the content of continuing nursing ,12 .50% CKD patiens knew the role of continuing nursing .Second ,demand :65 .76% -95 .11% CKD patiens had demand on disease treatment knowledge ,individual diet guidance ,regular telephone follow‐up ,and regular follow‐up nurse ;38 .04% - 53 .26% CKD patiens had urgent demand on individual diet guidance ,free health consultation ,and regu‐lar follow‐up nurse ;28 .89% CKD patiens had demand on electronic health record .Conclusion The cognitive of CKD patiens to continuing nursing is low and the demand is high .Hospital should to actively develop the continuation of local nursing service .

Objective To investigate the effect of water-immersion restraint stress(WRS) on nitric oxide(NO) production and its mechanism in rat platelets.Methods Male SD rats underwent WIR stress for 2,4 and 8 hours.Ulcer index(UI) of stomach was chedsed by Guth method,nitrite production was measured by Greiss assay,nitric oxide synthase(NOS) activities and L-arginine transport rate were determined by isotope tracer method.ResultsAfter 2 h WRS,the NO production,the NOS activity and L-arginine transport rate in rat platelets obviously increased and then gradually decreased.After 8 h of WRS,these parameters were decreased as compared with the control group.The gastric ulcer appeared and got more serious after 4 h WIR stress.Conclusion Short-term WRS up-regulates L-arginine /NO pathway and increases nitric oxide production in the platelets but long-term WIR stress has the reversed effect.
