Nine samples of oX-gallstong have been studied by scanning electron microscope and energy dispersive X-ray spectrometer. The determinative results indicated that calculus of Bos faurus domesticus Gmelin contained ten trace elements (Na, K, Ca, Mg, Zn, Fe, Cu,P, Cl,S), calculus of B.grunniens L. contained eight trace elements (Na, K, Ca, Fe, Cu,Ce, Cl, S), cultivate calculus of B. grunniens L. contained ten trace elements (Na, K ,Ca, Mg, Fe, Cu, P, Nd, Cl, S).Three species calculus all contained seven trace elements (Na, K, Ca, Fe, Cu, Cl, S), and the differences of their coontent were no significant.

Aqueous extract of Dracocephalum tanguticum Maxim. (DtM ),when given ig or ip to experimental hypoxia mice,markedly increased their tolerance to normobaric and hypobaric hypoxia. Erythrocyte superoxide dismutasc (SOD ) activity of mice or rats determined at high altitude (animaquing mountain 4700 m above sea level ) showed an elevated dismutation activity of peroxide anions. At an experimentally simulatcd altitude of 6000 m above sea level,determunation of MDA, Hb and Hct showed an obvious reduction of all the abnormally elevated criteria. It is suggested that the antihypoxia activity of DTM may be partly due to its free radical scavenging activity

The effects of an aqueous extract of Dracocephalum tanguticum Maxim. (DtM ) on p, b.b-1/ H. Hct. ESR. ESR-kand EPT of rats were studied by ip route. The animals were divided into three groups: normal pressure control group (NCG ). iowpressure treatment group (LTG )and lowpressure control group (LCG ). A11 p,b. Het. ESR-k increased stignificantly in rats exposed to stimulated altitude of 6500m for 10 days (8h/day),and the platelet and the ratio of left to ri1ght ventricle weights were obviously decreased in comparison with NPG. The above parameters of LTG .except Het.have noobvious difference as compared with NCG, Het in LTG increased obviously but lower than LCG. These results suggested that DtM may be used as an inhibitory agent against the changes of induced-hypoxia blood rheology, decreased platelet and hypertrophic right ventricle. In addition,the observation of tissue morphology showed that DtM possesses sometherapeutic effects to injuries of lung. liver and kidney of hypoxia rats.

Objective To observe the structure of cognitive injury and the effect of psychologic behavior training on cognitive function in community chronic schizophrenic patients. Methods80 healthy adults (control group) and 76 community chronic schizophrenia patients (research group) were assessed with World Health Organization-battery of cognitive assessment instrument for elderly (WHO-BCAI), mini-mental state examination (MMSE), and activities of daily living (ADL) pre- and post-psychologic behavior training. ResultsThere were significant differences in the scores of WHO-BCAI, MMSE, ADL between control group and research group (P<0.05 or P<0.01). 12 months after training, all the scores of research group significantly improved compared with that before training (P<0.05 or P<0.01). ConclusionCognitive disorders have occurred in the community chronic schizophrenia patients in wide range. Psychologic behavior training can improve their cognitive function.

Objective Using Wisconsin Stone Quality of Life questionnaire (WISQOL) to compare standard percutaneous nephrolithotomy(PCNL) and tubeless PCNL.Methods From January 2017 to June 2017,patients who met the criteria (no urinary tract infection,stones between 1-3 cm,hydronephrosis larger than 3cm,renal cortex thickness ＞ 2 cm and without serious heart,lung,liver and kidney dysfunction and coagulation dysfunction) and underwent PCNL were prospectively enrolled and randomized into 2 groups,standard PCNL group and tubeless PCNL group.Diclofenac sodium suppositories were used to relieve pain in all patients with obvious pain.The quality of life of these patients were estimated and compared by using WISQOL.Safety and efficacy were also estimated.Result At the end of the study,a total of 50 patients were included in the analysis.There were 24 patients in the standard PCNL group and 26 patients in the tubeless PCNL group.There were 9 male patients in the standard PCNL group and 17 male patients in the tubeless PCNL group.There was no significant difference in gender between the two groups.The differences between the standard PCNL group and tubeless PCNL group in mean age (yrs.) [(53.21 ±13.35) vs.(51.1 ± 11.5),P =0.55],stone diameter (mm) [(18.46 ± 5.58) vs.(18.75 ± 5.39),P =0.85],stone-free rate (23/24 vs.24/26,P =0.60),mean hemoglobin decline (g/L) [(11.87 ± 9.20)vs.(10.43 ± 8.49),P =0.56] were not significant.Mean dosage of acesodyne(pcs) in tubeless PCNL group (4.07 ± 1.49) was significantly less than that in standard PCNL group (7.54 ± 2.23).There were no patient need transfusion or postoperative fever management.The influence of perioperative quality of life of patients treated with tubeless PCNL is significantly better than those treated with standard PCNL in 16 items which includ energy,sleep,work and family,physical symptoms,concerns related to intimacy and travel,and general emotional well-being.Conclusion Tubeless PCNL can improve patients' quality of life compared with standard PCNL.

Objective To evaluate the prognostic value of the ratio of AR and AR-V7 expression in prostate cancer treated by castration therapy.Methods Immunohistochemical staining was performed in biopsy specimen of 136 prostate cancer patients received hormone therapy in Tongji Hospital of Huazhong University of Science and Technology from January 2010 to December 2015.Expression was determined using modified H score method.Patients aged from 53-96,the median age was 71,median tPSA value at diagnosed was 110.00 ng/ml(2.61-4 003.4 ng/ml),median fPSA value was 14.62 ng/ml(0.12-640.19 ng/ml),median PSA density was 1.15 ng/(ml · cm3) [0.02-62.63 ng/(ml · cm3)].Among these,88 (64.7％)patients were diagnosed Gleason score≥8,39(28.7％) patients with Gleason score 7,while 7 (6.6％) patients Gleason score ＜7.There were 54(39.7％) patients diagnosed T4 stage,57(41.9％)patients T3 stage and 25 (18.4％) patients Tx stage;62 (45.6％) patients were diagnosed N 1 stage,46 (33.8％) N0 stage and 28(20.6％) patients Nx stage;97(71.3％) patients were diagnosed M1 stage,30(22.1％) M0 stage,9 (6.6％) patients Mx stage.Cause-specific Cox regression and Kaplan-Meier Analysis were used to analyze the prognosis risk.Results The median follow-up time was 44 months,ranged 15-71 months.During the surveillance,the disease progression-free survival time ranged from 5-59 month,median 19 months.The overall survival time ranged from 12-61 months,median 31 months.Among these,79(58.1％) patients were AR positive and 26(19.1％) patients were AR-V7 positive,while AR and AR-V7 expression had no significant correlation (Spearman-test r =0.042,P =0.629).The AR-V7 positive patients showed significantly lower CRPC progression free survival (10.8 months vs.25.0 months,P ＜ 0.001) and much lower overall survival (20.3 months vs.42.8 months,P ＜ 0.001).The high AR-V7/AR expression ratio group showed significantly lower CRPC progression free survival (12.0 months vs.24.8 months,P ＜ 0.001) and much lower overall survival (22.5 months vs.42.8 months,P ＜ 0.001).In univariate Cox regression analyses,Gleason score at diagnosis,T stage,tPSA,PSA density and high AR-V7/AR expression ratio could predict the prognosis of hormonal therapy.While in multivariate Cox regression analyses,T stage(HR =2.597,95％ CI 1.351-4.995,P =0.004) and high AR-V7/AR expression ratio(HR =5.788,95％ CI 2.530-13.242,P ＜ 0.001) could effectively and independently predict the prognosis of hormonal therapy.Conclusion High AR-V7/AR HS ratio is the independent predictor of the prognosis of prostate cancer hormone therapy.AR-V7 positive and high AR-V7/AR HS ratio patients may have shorter PFS and overall survival time than AR-V7 negative and low AR-V7/AR HS ratio patients.
