Objective Toinvestigatetheeffectoffolicacidonplasmahomocysteine(Hcy)levels and vascular endothelial function in elderly cerebral infarction patients with hyperhomocysteinemia. Methods Thisstudywasaprospectivecontrolledtrial.Atotalof112elderlylacunarinfarction patients with high hyperhomocysteinemia admitted to the Department of Neurology,Nanjing Municipal Government Hospital from November 2012 to October 2013 were enrolled. The patients were divided into two groups according to the method of random number table. The patients of both groups received the conventional drug treatment of ischemic stroke at the same time. Fifty-six patients were in group A,and they were treated with folic acid 20 mg,once a day;56 patients were in group B,and they did not treat with folic acid. The Hcy levels on admission and after 24 weeks treatment were measured. Brachial artery flow-mediated endothelium-dependent dilation (FMD)was measured by high resolution ultrasound,and nitric oxide (NO), nitricoxidesynthase(NOS),andendothelin(ET)weredetectedatthesametime.Results Twenty-four weeks after treatment,the plasma Hcy level in group A was significantly decreased as compared with prior treatment (12. 2 ± 4. 2 vs. 22. 6 ± 3. 7μmol/L;P<0. 05),moreover,it was lower than the level of group B at the same period (12. 2 ± 4. 2 vs. 21. 8 ± 4. 0μmol/L;P <0. 05 ). The FMD level of group A was significantly higher than that of prior treatment and group B (11. 2 ± 3. 6 vs. 9. 2 ± 3. 3,9. 3 ± 3. 3;P<0. 05). The NO and NOS levels of group A at 24 weeks after treatment were significantly higher than those of prior treatment and group B at the same period (76. 2 ± 9. 4 vs. 49. 2 ± 9. 0,50. 0 ± 9. 1μmol/L,47. 6 ± 9. 5 vs.38. 4 ± 7. 5,37. 8 ± 8. 8 kU/L;P<0.05). The ET level of group A was decreased as compared with that of prior treatment and group B at the same period (81. 3 ± 20. 5 vs. 105. 6 ± 25. 2,105. 3 ± 21. 8 ng/L;P<0.05).NoadversereactionwasfoundduringthetreatmentingroupA.Conclusion Alargerdoseof folic acid can significantly reduce the plasma Hcy level,decrease the FMD level,and ameliorate vascular endothelial function in elderly cerebral infarction patients with hyperhomocysteinemia.

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.

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.

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 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.

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 clinical results of endoscopic vein harvesting(EVH) in patients who underwent coronary artery bypass grafting(CABG).Methods From July 2013 to October 2014,500 patients who underwent isolate CABG in our institution were divided into two groups:EVH group (n =250) and open vein harvesting(OVH) group(n =250).The surgical result and perioperative complications were compared between the two groups.Results The procedures were completed successfully in all the patients in both groups.There was no significant difference existed in the length of the harvested vein and vein injury between the two groups(P ＞ 0.05).Similar results were obtained in the in-hospital mortality.Compared to group OVH,group EVH showed significantly shorter harvesting time,smaller incision,and lower rates of perioperative leg complications (P ＜ 0.01).Group EVH had a less bed staying time after operation and a shorter post-operation hospital stay (P ＜ 0.05).EVH group achieved an improved patient satisfaction and postoperative pain when compared with OVH in CABG(P ＜0.05).Conclusion EVH can provide adequate vein graft for CABG,and also significantly reduce wound related complications when compared with OVH.EVH is recommended for vein harvesting to improve patient satisfaction.
