Objective To evaluate the sanitation of the ecological toilet systems used in rural areas. Methods The urine diverting Ecosan toilets in rural areas of Guangxi province were observed for the utilization, maintenance and sanitization. The hygienic evaluation was carried out according to the Hygienic Standards for Excreta Sanitization GB 7959-87. Results The new type of urine diverting Ecosan toilets could meet the requirements of non-hazard treatment of excreta. Conclusion Such toilet system should be developed in most parts of Guangxi.

Objective To explore the work environment of male nurses of psychiatric in Chongqing, as well as the affecting factors. Methods The Professional Practice Environment (PPE) scale was applied to investigate the work environment of 400 male nurses of psychiatric in Chongqing. And the regression analysis was used to analyze the associated factors. Results staff relationships with physicianswas the subscale with the highest score (3.15 ± 0.41) of the PPE of the tested male nurses of psychiatric in Chongqing, whileteamworkwas the subscale with the lowest score (2.05±0.70). Locations and types of hospitals,nurse-patient ratios and education of male nurses were identified to be predictors of work environment (t=- 14.19- 7.63, P<0.01). Conclusions Multiple factors affecting the work environment of male nurses of psychiatric should be considered when nursing managers draw up management strategies.

Objective To explore motivation alteration influencing factors of internet addiction disorder (IAD) undergraduates.Methods The study sampled randomly 793 undergraduates from China University.According to CIAS-R and Young's internet addiction diagnostic criteria,a total of 37 internet addicts were selected.Internet addiction survey was used to study the motivation alteration influencing factors of IAD undergraduates.Results (1) The negative effect of internet using on academy,personal relationship etc.(damage from internet using) had a significant positive correlation with motivation alteration (r =0.672,0.699,0.658,P ＜ 0.01 ; r =0.653,0.673,0.628,P ＜ 0.01 ; r =0.604,0.681,0.703,P ＜ 0.01).(2) Benefit from psychological satisfactory level of internet using had no significant difference with motivation alteration.(3) Self-efficiency of behavioral control on using internet had a significant negative correlation with motivation alteration (r =-0.397,-0.370,P ＜0.05).Conclusion The motivation alteration of IAD undergraduates is influenced by the factors of damage from internet using,sense of achievement,self-efficiency of behavioral control on using internet and so on.

Objiective To assess the feasibility of transurethral non-muscle invasive resection or electrocautery of bladder tumor (TURBT) under local anesthesia. Methods Ten patients with non-muscle invasive bladder cancer (NMIBC) history, who were confirmed NMIBC relapse by imaging and cystoscopy were selectively implemented TURBT or electrocautery under local anesthesia. Patients′anesthesia and tolerance under different local anesthesia were observed. Results All surgeries were completed successfully with clear base and without residual tumor. Tumor tissues were pathologically confirmed NMIBC. Patients were well tolerated to local anesthesia. The situation of pain scores were 0 point in 2 cases, 1 point in 4 cases, 2 points in 3 cases and 3 points in 1 case. Conclusions For NMIBC patients with poor surgery tolerance and high anesthetic risk and on the basis of low pressure on the bladder, selectively implementing TURBT or electrocautery under sufficient urethral anesthesia is feasible from the perspective of cancer cure and patients′tolerance.

The chemical constituents from lipophilic parts in the roots of Angelica dahurica var. formosana cv. Chuanbaizhi were studied in this paper. The compounds were separated and purified by repeated column chromatographic methods on silica gel and HPLC, and the chemical structures of compounds were determined by spectral data analyses. Twenty-nine compounds were obtained and identified as isoimperatorin (1), β-sitosterol (2), imperatorin (3), bergapten (4), osthenol (5), xanthotoxin (6), isoimpinellin (7), dehydrogeijerin (8), phellopterin (9), isodemethylfuropinarine (10), 7-demethylsuberosin (11), alloimperatorin (12), xanthotoxol (13), isooxypeucedanin (14), alloisoimperatorin (15), demethylfuropinarine (16), 5-hydroxy-8-methoxypsoralen (17), oxypeucedanin methanolate (18), pabulenol (19), byakangelicin (20), marmesin (21), (+) -decursinol (22), heraclenol (23), oxypeucedanin hydrate (24), marmesinin (25), ulopterol (26), erythro-guaiacylglycerol-β-ferulic acid ether (27), threo-guaiacylglycerol-β-ferulic acid ether (28), and uracil (29). Compounds 5, 8, 11, 18, 21-23, and 26-28 were obtained from the roots of title plant for the first time.

A non spore fungal strain designated as CR 9512 was isolated from a species of Cordyceps , found in Northern Guangdong of China The growth characteristics and the morphology of the organism were studied It was initially identified as Rhizoctonia sp ,Agonomycetales Its antimicrobial tests, against 26 strains of Gram positive and Gram negative bacteria, actinomycetes, filamentous fungi and yeast, showed strong inhibition to some yeast of Rhodotorula, Saccharomyces, Pichia and Cryptococcus , and weak inhibition to yeast of Candida The speciality on a limited spectrum anti yeast of the organism will show an enormous value for researches and applications

Objective To explore the value of strain rate imaging (SRI) technology in the diagnosis of hypertension patient with re-gional left ventricular early diastolic dysfunction. Methods 50 essential hypertension patients were divided into hypertension Group Ⅰ and Group Ⅱ, including 31 patients with normal left ventricular and 19 patients with left ventricular hypertrophy. 25 healthy people were used as the control group. SRI was done in the six different basal myocardial segments and the parameters of SRI were compared with that of Doppler tissue imaging (DTI) and pulse Doppler (PW). Results In the hypertension group, SRe of the six different basal myocardial segments was lower than that in the control group (P<0.05), but (SRa) of hypertension group was higher (P<0.05). SRe was negatively correlated with the patients'illness development (r=-0.89, P<0.05), but SRa was positively correlated (r=0.97, P<0.05). And the SRe/SRa<1 detection rate of Group Ⅱ was higher than that in Group Ⅰ, and the ratio in the control group was lowest(P<0.05). Total detection rate of SRI (88%) was higher than Em/Am <1 of DTI (79.67%) and E/A < 1 of PW(60%), and these changes were more obvious in Group Ⅰ. SRI was higher than DTT and PW (P<0.05). Conclusion Compared with traditional technology and methods, SRI could pro-vide more accurate diagnoses to hypertension patient with regional left ventricular early diastolic dysfunction.
