Objective To explore the total anti-oxidation capacity(T-AOC), superoxide dismutase(SOD), nitric oxide synthase(NOS) and nitric oxide(NO) in testis homogenate of the rats’ with chronic fluorosis induced by drinking NaF solutions with different concentration. Methods 24 male Wistar rats were divided into 3 groups (8 rats per group) including control group, low-fluoride(LF) group, high-fluoride(HF) group, which were exposed to fluoride by means of freely drinking tap water containing NaF with 0, 100 and 200 mg/L respectively for 20 weeks. T-AOC, NOS activities and SOD activity of the testis tissue were determined by colorimetry , xanthine oxidase method and nitrate reductase method respectively. Results Compared with the control group, the T-AOC of the testis tissue increased significantly in LF group and decreased significantly in HF group. SOD activity of the testis tissue showed on significant difference among the control group, LF group and HF group . Compared with the control group, the levels of NOS and NO decreased significantly in LF group and increased significantly in HF group. Conclusion The T-AOC of the testis tissue exposed to low level of fluoride presents a compensatory increase induced by the inhibited activity of NOS and synthesis of NO. Higher level of fluoride may increase reactive oxygen species(ROS), and cause abnormal expression of induce nitric oxide synthase(iNOS) and increased synthesis of NO in the testis tissue.

OBJECTIVE:To observe the efficacy and safety of amitriptyline combined with carbamazepine in the treatment of postherpetic neuralgia(PHN). METHODS:80 patients with PHN were randomly divided into observation group and control group. Control group was orally given Carbamazepine tablets 100 mg,bid,then increased to 100 mg,tid after 3 d. Observation group was additionally given Amitriptyline tablets 12.5 mg every night before bed,d1~3;then increased to 25 mg after 3 d every night be-fore bed,d4~5;and 12.5 mg every morning from 6th d+25 mg every night before bed,and the dose could be adjusted based on the pain and adverse reactions of 2 groups. The treatment course for 2 groups was 4 weeks. Visual analogue scale score(VAS),sleep-ing time,pain disappearing time and clinical efficacy in 2 groups were compared,and the incidence of adverse reactions were re-corded. RESULTS:The total effective rate in observation group was higher than control group,VAS was lower than control group, sleeping time was longer than control group and pain disappearing time was shorter than control group,the differences were statisti-cally significant(P<0.05). There was significant difference in the incidence of adverse reactions between 2 groups(P>0.05). CON-CLUSIONS:Amitriptyline combined with carbamazepine has obvious efficacy in the treatment of PHN,with good safety.

Purpose To explore the relationship between epicardial adipose tissue (EAT) volume and ascending aortic stiffness by CT,so as to early evaluate the lesions of ascending aortic by measuring EAT.Materials and Methods 169 patients with suspected coronary artery disease who underwent coronary CT angiography and coronary angiography in First Affiliated Hospital of Jinzhou Medical University from January 2016 to September 2016 were enrolled.According to the presence of coronary atherosclerosis or not,the patients were divided into research group (109 cases) and control group (60 cases).The research group were further divided into slight,mild,moderate and severe group according to the Gensini score of coronary atherosclerosis.The recorded threshold of EAT volume was 107.2 cm3.The patients with EAT volume higher than 107.2 cm3 belonged to the exposure group,and the rest belonged to the non exposure group.The EAT volume and ascending aortic stiffness were measured,and the relationship between them was assessed.The relationship between EAT volume and coronary atherosclerosis was also analyzed.Results In the control group,there was no correlation between EAT volume and ascending aortic stiffness (r =-0.156,P＞0.05).However,there were negative correlations between EAT volume and ascending aortic stiffness in slight,mild,moderate and severe group (r=-0.378,-0.340,-0.514 and-0.459,P＜0.05).The EAT volumewas an independent risk factor of ascending aortic stiffness (β=-0.009,t=-2.653,P＜0.05).The incidence of CAD in the exposure group was 9.318 times of that in the non exposure group.Conclusion There is obvious correlation between EAT volume and ascending aortic stiffness in patients with CAD.The evaluation of EAT volume can provide an effective reference for the early prediction of ascending aortic lesions in patients with CAD.
