Objective To investigate the effects of iri doid on the spermatogenesis in mice of type-2 diabetes induced by nicotinamide and streptozotocin. Methods Fifty-six male C57BL mice were randomly divided into seven groups (n=8 for each group):control group, diabetic group, diabetic and glibenclamide (0.25 mg/kg) group, diabetic and iridoid (20 and 40 mg/kg) group, and iridoid (20 and 40 mg/kg) group. Diabetic model was induced by intraperitoneal injection of streptozotocin (65 mg/kg) and nicotinamide (120 mg/kg). Glibenclamide and iridoid were orally fed for 28 days. Twenty-four hours after the last treatment, blood samples, testis and the epididymis were collected for detecting blood hormones, testicular biopsy, and the evaluation of sperm parameters. Results The body weights of diabetic mice were recovered from the reduction after treatment with 40 mg/kg of iridoid and glibenclamide(P<0.05). The sperm count and viability were significantly decreased in diabetic group compared with those of control group (P<0.05). The sperm count was significantly increased in diabetic and glibenclamide group than that of diabetic group (P<0.05). The serum levels of lutein hormone (LH), follicle stimulating hormone (FSH) and testosterone (T) were significantly decreased in diabetic group compared with those of control group (P<0.05). The serum levels of LH, FSH and T were increased after treatment with 40 mg/kg of iridoid and glibenclamide (P<0.05). Conclusion These results suggest that iridoid can reduce the level of oxidative damage in
diabetic mice, and effectively improve the fertility of mice.

Cleft lip and palate (CLP) is one of common congenital malformations. The evaluation of upper airway morphology using two-dimensional (2D) and three-dimensional (3D) imaging data for CLP patients has important clinical significance. Studies have adopted various measurement methods,in which different anatomical landmarks and reference planes are used in 2D cephalometric measurement. Shooting positioning for cone beam computed tomography (CBCT), measurement software, reference plane, landmark selection, and measurement method in 3D studiesare also different. Currently,comparison is unable to be performed across different studies due to various measurement methods and measurement standards. This article reviews studies on upper airway morphology measurement in CLP patients.

Aesthetics of science is truly present.But only those people who have ability to appreciate the beautiful can comprehend the aesthetics of science.Aesthetics of science is a senior pattern of aesthetics.Aesthetics of science can arouse people to explore knowledge and truth.Aesthetics of science bring first light of morning to medical science education which has lots of beautiful material.Recognizing aesthetics of science in medical science education is helpful to cultivating the higher quality persons with ability of medicine and training aesthetic accomplishment.

OBJECTIVE:To discuss the development of the core competitive power of domestic vitamin C manufacturing enterprises.METHODS:To analyse the characteristic of vitamin C industry in China and the competitive situation in the new market enviroment after China entry into WTO and to study the value chain of Chinese enterprises.RESULTS&CONCLU?SION:In order to develop the new core competitive power,it is important to breed the core of value chain that is based on in?novation.

As for pediatric patients,antibacterial drugs are the most common prescription drugs.These agents play a significant role in reducing the incidence and mortality of human infections.However,at the same time,some related adverse reactions appeared,such as the impact on intestinal microflora colonization.Intestinal microbial population has great importance in regulating body's metabolism.If early use of antibiotics in life,the composition of the intestinal microbiota will be destroyed,and resulting in obesity.Animal experiments showed that low-dose antibiotics may promote an increase in body weight,and the use of antimicrobial drugs in the early life was more effective than that in late stage.Currently,available human epidemiological investigation indicated that antibacterial drugs had a similar effect in human.Gut flora in early life is essential for the later metabolism of body,but it is susceptible to interference.Using probiotics after the application of antimicrobial drug may be beneficial to improve the balance of intestinal microflora.This may be a new direction to prevent obesity after the early use of antimicrobial drugs.Now,the domestic and foreign reports were combined to elaborate the antibacterial drug metabolism in animals,the influence of body quality on the quality of the human body and the corresponding measures after application of antimicrobial agents.

Objective To explore the correlation between nurses' work alienation and silence behavior.Methods 603 registered nurses were recruited from a tertiary hospital in Guangzhou.They were investigated with Alienation Scale and Work Silence Behavior Scale.Results The scores of work alienation and silence behavior were (34.35±6.53) points and (37.66±6.46) points respectively,and both of them were at the medial level.Work alienation was positively related to silence behavior (r=0.603).All dimensions of work alienation were positively related to all dimensions of silence behavior (P ＜ 0.01).The predictors of silence behavior were age,nursing working years,job title,department,frustration,helplessness and meaningless,explained 42.2％ of its variance.Conclusions Work alienation has positive effect to silence behavior.The administrators in hospitals should focus on nurse,work alienation and silence behavior,and reduce silence behavior by reducing work alienation.

OBJECTIVE:To provide references for the management and use of the donated drugs for earthquake resistance and disaster relief.METHODS:The problems appeared in the management and use of the donated drugs after the earthquake occurred on May 12,2008 in Sichuan province of China were summarized analytically and the corresponding suggestions were put forward.RESULTS & CONCLUSION:Some problems such as the turnover of the drugs,the expiration date,drug dispensing and allocation etc appeared in the management and use of the donated drugs,which should be standardized by setting related laws and regulations to make more greater use of the limited drug resource in the disaster relieving.
