AIM:To study the sedation, diuresis and anticoagulation effects of Ji-Ming-San (JMS) in animal models for exploring the circadian variations of the dosing action and verifying the rationality of administering JMS on special time. METHODS: The sedation effect and circadian difference were determined by observing the time session of ambulation, raising double-forefoot test and autonomic activity of model mice. The diuretic effect and the circadian variation in rats were examined by metabolic cage test while the anticoagulation and the circadian change were observed by glass test. RESULTS: JMS produced significant sedation effect by reducing time session of ambulation, raising upper limbs frequencies/time and autonomic activity and the built-in rhythm with autonomic activity disappeared after JMS administration. JMS had satisfactory diuretic effect and total urinary output in water-loaded rats was increased after dosing. The diuretic effect of dosing showed a circadian rhythm with more significant output during the night than that during the daytime. Also, JMS prolonged the clotting time significantly and the action exhibited circadian difference. As compared with administration at the night, the clotting time was more prolonged at the daytime. CONCLUSION: JMS can produce obvious sedation, diuresis and anticoagulation effects with varied circadian rhythm. The findings suggest that the effect of administering JMS is better at the end of rest phase than other time session.

Objective To explore the role of leptin,COX-2 and p27 in bile-induced gastric mucosal injury in rats.Methods SD rats were divided into 4 groups: DGR(duodenogastric reflux) group,DGR+BDL(ligation of bile duct) group,BDL group and control group.The pathological changes of gastric mucosa and tight junction were observed,DIXON scores were warked out after 3 months.Immunohistochemistry was used to detect the expression of leptin,COX-2 and p27 in gastric mucosa with different lesions. Results The DIXON scores in DGR and DGR+BDL group were higher than those in BDL group and control group(P

Cotinine is the best biomarker for the assessment of the exposure to environmental tobacco smoke(ETS).With the"Framework Convention on Tobacco Control"implemented in China,the hazards from ETS are increasingly concerned,the determination of cotinine in human body which reflects the internal exposure to ETS received universal recognition day by day.It is imperative to create a standardized,simple and fast method to detect cotinine in human body.The recent determination techniques of cotinine,the application in different human samples and the direction of development were introduced in the present paper.

Keratocytes situated between the collagen lamellae in the corneal stroma,are mitotically quiescent cells.The cells can secrete collagens and keratan sulfate proteoglycans which contribute to the transparency of the cornea.Upon injury,keratocytes are stimulated to corrent apoptosis and transite into repair phenotypes,fibroblast and myofibroblast.These repair phenotypes can either promote regeneration or induce fibrotic scar,and the latter is detrimental to the otherwise transparent cornea.Moreover,a population of keratocytes can be induced to appear the stem cell-like characteristics.Therefore,keratocytes are no longer bystanders,but active participants in numerous functions.

Objective To learn the change of serum thymidine Kinase 1(TK1) level in the treatment process of the early cure nasopharyngeal carcinoma patients and its relationship to pathological features .Methods From January 2010 to December 2013 ,35 cases of nasopharyngeal carcinoma patients were collected into our study ,20 cases of nasopharyngeal inflammation patients were chosen as the control .Serum TK1 level in the 2 groups was compared before and after treatment .Results TK1 in control group had no significant differences before and after treatment (P>0 .05) .Compared with the control group ,serum TK1 in nasopharyngeal carcinoma group were higher before and after radiotherapy (P<0 .05);after radiotherapy ,serums TK1 in nasopharyngeal carcinoma group were lower(P<0 .05) .Before and after radiotherapy ,serum TK1 Ⅰ and Ⅱ stage were lower than in Ⅲ and Ⅳ stager(P<0 .05) ,lymph node metastasis group were higher than no lymph node metastasisr (P<0 .05) ,TK1 had higher expression in TNMⅣ than TNM Ⅱ(P<0 .05) ,compared with lymph node metastasis and cervical nerve violated groups ,TK1 expression was higher in none lymph node metastasis and none cervical nerve violated groups (P<0 .05) .Conclusion TK1 can reflect the tumor load and proliferative activity of nasopharyngeal carcinoma ,which could be as a factor in nasopharyngeal carcinoma diagnosis ,monitoring and prognosis .

Objective To evaluate the feasibility and efficacy of the ultrasonic technology,digital subtraction angiography(DSA) combined guide line of liver abscess drainage tube.Methods 70 patients with liver abscess received ultrasonic technology,DSA joint drainage tube after treatment.Using ultrasound technology and DSA of complementary advantages,enhancement in the operation was good,especially the liver abscess of abdominal pneumatosis was more and more room,enhancement effect was better than that of pure guided by ultrasound.Results 70 patients were all successful puncture and catheter,development was good,all 70 cases cured,without any serious complication.Conclusion Ultrasound technology,DSA joint guided puncture catheter drainage is a safe,minimally invasive treatment,has significant efficacy and important clinical value.

The concrete methods and experiences for foreign students in case study in the past decades were introduced in this article. We emphasized on teaching students in accordance with their aptitude and step by step, explaining the profound things in a simple way and giving attention to different students' capabilities during teaching. In the practice, we surely felt that case study will bring more advantage than traditional teaching methods, motivate students and improve the capabilities to understand the course content.

Two-way choice is the main way for the seven-year-program clinical medical students and postgraduate supervisors.This article analyzes the influence factors and shortages of two-way choice for postgraduate supervisors and seven-year-program clinical medical students.This investigation discovers that the supervisor's abilities of research,teaching and clinical and their personal magnetism are important and key factors.The students' gender,character,hobbies and interests and the familiarity to profession are the secondary factors.The other factors that include employment status,the level of income and the advice of parents and friends also have influence on two-way choice for postgraduate supervisors and seven-year-program clinical medical students.In order to further improve the tow-way choice,the author gives some suggestions,including introducing profession and the scientific researches of supervisors in advance,encouraging the face-to-face communication between students and supervisors,promoting multiple profession choices and giving some aids to the students for choosing the supervisors.
