Green hospital construction is a new challenge for medical industry after global sustainable development strategy was put forward. The core connotation of green hospital includes green building, green healthcare, patient safety, and doctor-patient harmony. Many countries have established green building evaluation system to deal with energy crisis. Leadership in Energy and Environmental Design (LEED), Green Guide for Health Care (GGHC) in the U.S., and Evaluation System for Green Hospital Building (CSUS/GBC 2-2011) in China have guiding signiifcance for the development of green hospitals in China. The evaluation system of green hospitals home and abroad still focuses on green building, and establishment of suitable synthesis evaluation system of green hospitals in China needs further research.

Objective To comparing the diagnostic and therapeutic strategies for patients with benign prostatic hyperplasia(BPH) between doctors in general hospitals and community hospitals,and to provide scientific clues for the standardization in medical practice.Methods General and community hospitals in urban China were selected via the stratified sampling.127,325 outpatients in these hospitals from December 2011 to December 2012 were randomly recruited.Results The average age of patients was(67.82±8.62) years.There were significant differences in I-PSS,prostate volume,urinary flow rate(UFR) and result of digital rectal examination(DRE) between patients in general and community hospitals.The rates of diagnostic applications were different between doctors in the two kinds of hospitals except I-PSS.Compared with community hospitals,DRE was more frequently applied while ultrasonic inspection and UFR test were less used in general hospitals in North China.A totally opposite situation was observed in East China as compared with the north.The application rates of DRE and UFR test were lower and ultrasonic inspection rate was higher in community hospitals than in general hospitals in South China.Pharmacotherapy was the most common treatment for BPH patients in both types of hospitals(97.53 ％).The rates of drug combinations were statistically different but both were close to 75％ in the two types of hospitals.In community hospitals,the percentage of patients receiving watchful waiting with severe symptoms and signs were lower than that of patients receiving watchful waiting with moderate symptoms and signs,but the percentage of patients receiving operation was not significantly increased.On the contrary,the percentage of patients receiving operation with severe symptoms and signs was higher than that of patients receiving operation with moderate symptoms and signs in general hospitals,but the percentage of patients receiving watchful waiting was not decreased.Conclusions Applications of diagnostic methods are significantly different between doctors in general hospitals and community hospitals and vary among regions.Therapeutic strategies are correlated with the severity of obstructive symptoms or signs.The medication strategy is similar between the two types of doctors.

Objective To promote the standardization of medical practice in China by comparing the discrepancies of diagnosis and medication strategies for benign prostatic hyperplasia (BPH) between urologists and geriatricians.Methods Departments of urology and geriatrics in general hospitals in China were selected through stratified sampling and 145 315 patients who went for the outpatient service in certain days during December 2011 to December 2012 were recruited by cluster.Questionnaires were completed by corresponding doctors and data of patient clinical characteristics as well as diagnostic and therapeutic pattern were collected.Results A total of 142 511 valid questionnaires were collected with 119 426 from urology and 23 085 from geriatrics.The average age of BPH patients was (68.34±8.61) years and the average IPSS was 17.93±4.73.The rates of diagnostic method were IPSS (99.2％),ultrasonic inspection (86.0％),digital rectal examination (DRE) (66.0％) and urine flow rate test (55.2％).The rate of ultrasonic application was lower while the rates of other methods were higher among urologists (P＜0.01) ; the rate of DRE among urologists was 2.2 times to that among geriatricians.For patients with moderate or severe symptoms,most urologists (72.1％ in moderate patients and 79.9％ in severe patients) applied drug-combination strategy and the rate was 2 times to that among geriatricians (P＜0.01).In contrast,most geriatricians (59.7％ in moderate patients and 56.1％ in severe patients) applied single drug to BPH patients.Urologists utilized α-receptor blockers,plant preparations and traditional Chinese medicine more frequently than geriatricians (P＜0.01).Conclusions Urologists performed more integrated diagnosis strategy compared with geriatricians.The urologists tended to use 5α-reductase inhibitor combined with α-receptor blocker to treat BPH patients with moderate or severe symptoms,while geriatricians preferred 5α-reductase inhibitor alone.

OBJECTIVE: To establish a scientific foundation for cosmetic supervision and administration based on the analysis of the sanitary quality of cosmetics in Hunan Province during 2010. METHODS: According to Cosmetic Sanitary Standards (set by the Ministry of Health, People's Republic of China), 150 random samples of cosmetics in Hunan were assayed both for microbial items (including total plate count, fungus and yeast, fecal coliform, staphylococcus aureus, pseudomonas aeruginosa) and chemical items (including 17 kinds of prohibited substances and 14 kinds of restricted substances). RESULTS: The total rate of cosmetics failing to meet the standards was 22.0% of the 150 samples; specific rates for failing perfumes, skin care products (eye cream) and deodorant products were, relatively, 70.6%, 60.00%, and 44.4%. Four kinds of prohibited substances, including diethyl phthalate, acrylamide, asbestos and neodymium, as well as 2 kinds of restricted substances, including triclosan and formaldehyde, were found to exceed standards. None of microbial items exceeded standard levels. CONCLUSION The sanitary quality control of cosmetics is lax. Administrative departments should not only reinforce their post-production supervision with respect to cosmetics, but also consolidate their control over the process of cosmetic production in order to solve the problem of toxic residues or illegal and intentional adulterations.

Prohibited substances in cosmetics refer to substances which must not be among the raw material ingredients of cosmetic products. These substances are absorbed mostly through skin, as well as via lung and gastrointestinal tract. Polyacrylamide is ubiquitously used in industry and its decomposition residue acrylamide (ACR) easily finds its way into cosmetic products. ACR can either be oxidized to epoxide glycidamide or conjugated with glutathione, hemoglobin or DNA; ultimately it is excreted in urine. ACR causes neurotoxicity, reproductive toxicity and tumors in rodents. Occupational exposure to ACR causes neurotoxicity in humans; however, epidemiological evidence have not unambiguously answered the question of whether ACR exposure can increase cancer risk for humans.

OBJECTIVE: To evaluate the effect of nutrition and food safety education among middle school students in a poverty-stricken county in west China, and to explore the better education model for further education. METHODS: Students of grade 7 to 9 were selected from 4 middle schools in the country through multi-stage cluster sampling for the questionnaire, and the schools were assigned into an intervention group or a control group. After students in the intervention schools completed one year nutrition and food safety education with the textbooks, students were chosen from the same 4 schools to finish the same questionnaire again. RESULTS: A total of 410 students from grade 7 to 9 were selected at the baseline study, and 474 students in the final study. The essential characteristics of the 2 groups were not statistically significant (P>0.05). In the baseline investigation, the differences in the scores on nutrition and food safety knowledge, attitude and practice between the 2 groups were not significant (P>0.05). In the final study, the scores on the knowledge, attitude of nutrition knowledge learning, and dietary habits among students in the intervention group were significantly higher than those in the control group (P<0.05). School-students mixed model demonstrated that the intervention was protective factor on scores of knowledge, in particular with nutrition related diseases and reasonable diet (P<0.05). But the intervention didn't affect the scores on attitude in both ways (P>0.05). CONCLUSION Nutrition and food safety education can improve the nutrition and food safety knowledge effectively. The curriculum should be further standardized and different emphases should be set up to different grades to cultivate healthy diet behaviors.

The recovery force of Ti-Nb coated and uncoated TiNi shape memory alloy rods was investigated. The rods were 6.0 mm, 6.5 mm and 7.0 mm in diameter respectively. The mean transition temperature was 33.0 degrees C. The rods were stored at -18 degrees C and pre-bent with a three-point bending fixture, the span was 20. 0 centimeters and the deflections were 5.0 mm, 10.0 mm, 15.0 mm and 20.0 mm, respectively. The rods were then heated in a constant temperature saline solution chamber. The experimental temperature was 37.0 C and 50.0 C respectively. The recovery force was measured in a constant displacement mode on biomaterial test machine. The results showed that the recovery force of the memory alloy rod increased with increasing recovery temperature, rod diameter and deformation of both Ti-Nb coated and uncoated surface. The recovery force of Ti-Nb coated rods of 6.0 and 6.5 millimeter in diameter was lower than the uncoated rods in the same diameter. However, the recovery force of 7.0-mm-diameter rods showed no significant difference between coated and uncoated surface.
