ObjectiveTo investigate the role of iNOS in the middle and late stage of pulmonary hypertension (PH) and the effect of L-Arginine(L-Arg) on these stage.MethodsThirty healthy male SD rats were randomly divided into five groups.All rats except those in control group were injected intraperitoneally (ip) with a single dose (50 mg/kg) of MCT to induce PH.Then the L3 and L5 groups were injected ip with 500 mg/kg L-Arg daily for 3 weeks and 5weeks respectively,the M3 and M5groups received a daily ip injection of the same amount of saline as L-Arg for 3 weeks and 5 weeks respectively; the same amount of saline was injected ip daily in control group for 5 weeks.Right ventricular systolic pressure(RVSP) was measured before lungs were excised for immunohistochemistry at the end of experiments. ResultsThe expressions of iNOS and elastin in M3 and M5 were higher compared to the control group,but L-Arg partly reduced the expressions of iNOS and elastin both at 3weeks and 5 weeks post-MCT.The reduction of eNOS expression in L3 and L5 groups were lower compared to M3 and M5 groups,but the eNOS expression in L3 and L5 groups were still lower than control group.ConclusionDuring the middle and late stage of PH,the expression of eNOS was decreased.The expression of iNOS was induced,which would produce numerous NO.However,these NO had no benefit on the development of PH.L-Arg could restore the balance of eNOS and iNOS,and could inhibit the development of PH,which may provide a new clues to explore the pathogenesis and treatment of PH.

Objective To explore the clinical application value of blood routine examination in judgment of the activity of inflammatory bowel diseases.Methods 102 patients with inflammatory bowel disease were selected as the main research objects,60 healthy persons in the same period were selected as the control group,all of the subjects were received routine testing of blood,C-reactive protein and erythrocyte sedimentation rate,and the relationships between disease and blood routine indexes were compared.Results In UC group,the PLT,WBC RDW index levels of remission were higher than those of the control group,the differences were statistically significant(t =6.75,8.21,5.73,all P ＜0.05).In patients with UC,the HGB,HCTand MPV index levels were lower than those in the remission patients and the control group,the differences were statistically significant(t =8.12,11.03,6.72,9.35,10.23,8.71,all P ＜0.05).But the PLT index was higher than that of patients in remission,the RDW and WBC indexes were higher than those in the control group and the remission period,there were statistically significant differences (t =7.59,8.51,6.03,all P ＜ 0.05).The routine blood indexes of the relief patients of CD group had significant differences compared with the control group(t =6.17,7.29,9.01,10.35,8.27,7.69,8.01,9.91,allP ＜ 0.05),the HCT,MCV,HGB and MPV indexes were lower than those of the control group,the differences were statistically significant (t =9.01,10.35,8.27,9.9i,all P ＜ 0.05),the WBC,PLT,N and RDW indexes were higher than those of the control group,the differences were statistically significant (t =6.17,7.29,7.69,8.01,all P ＜ 0.05).In UC group,the HGB,HCT,MCV and MPV indexes were lower than those in the remission patients and the control group,there were statistically significant differences(t =8.19,6.97,7.53,9.02,all P ＜ 0.05).But the PLT,RDW,WBC and N indexes were higher than those in the remission patients and the control group,the differences were statistically significant (t =9.81,7.94,8.36,7.61,P ＜ 0.05).In the active patients of CD group,the WBC and N indexes were significantly higher than those of UC group,the differences were statistically significant (t =8.15,9.07,all P ＜ 0.05).In the remission patients of CD group,the PLT index was significandy higher than that in the remission patients of UC group,the difference was statistically significant (t =10.35,P ＜ 0.05).Conclusion Indexes of blood routine has obvious significance in activity of inflammatory bowel disease,and it is significant correlation with inflammation index,which can be used as one of the routine clinical method to determine the activity of inflammatory bowel diseases.

Objective · To compare the prevalence of tobacco advertisement before and after implementation of the new edition of Advertising Law of the People's Republic of China and evaluate the effects of implementation of the new Advertising Law. Methods · Tobacco sales places, public places, and streets in Shanghai were randomly selected to observe tobacco advertisement and complete the survey. The survey was carried out in 10 districts of Shanghai in June 2015 with 10 tobacco sales places selected in each district, and in 4 districts of Shanghai in June 2016 with 25 tobacco sales places selected in each district. Sales places included convenient stores, tobacco stores, supermarkets, and kiosks. In addition, public transport waiting points, public transport vehicles, hospitals, shopping centers, restaurants, bars, and Internet cafes were selected into survey in 2016. Results · In 2016, the proportion of tobacco sales places having tobacco advertisement was lower than that in 2015, but the proportion of tobacco promotion behaviors was higher. In 2016, 128 public places and streets were investigated and only 1 had outdoor tobacco advertisement. Conclusion · The new edition of Advertising Law has significant effect on controlling tobacco advertisement, but tobacco sales places still have tobacco advertisement with various disguised promotion forms. Tobacco sales places have diversified business styles and minors often enter these places. It is recommended that a clear definition of disguised forms of tobacco advertisement should be made, tobacco advertisement at tobacco sales places needs to be supervised, the release of tobacco advertisement should be strictly reviewed, and existing tobacco advertisement should be severely punished, so as to prevent minors from exposing to tobacco advertisement and information luring smoking.

Objective To study the effects of an extended-interval dosing regimen of gonadotropin releasing hormone agonist(GnRH-a) in the treatment of adenomyosis. Methods 20 patients with adenomyosis who asked for medicine treatment were divided into two groups randomly(n=10). The patients in the study group were given four doses of triptorelin depot 3. 75mg every 6 weeks in a new extended-interval dosing regimen. The other patients in the control group were given triptorelin 3.75mg in the conventional depot regimen of six doses,each given 4 weeks apart. The changes of degree of dysmenorrhea and the uterine volume were investigated. And the level of sexual hormone was also detected both before and after therapy.Results After six months of therapy,the reliving rate of dysmenorrheal was 100% both in the new regimen and the conventional regimen. The uterine volume was reduced at 46.7 % and 47. 5 % . And the level of LH, FSH and E2 were decreased significantly(P 0.05).Conclusion The use of the extended-interval dosing regimen of triptorelin depot in adenomyosis results in a consistent hypoestrogenised state,which is similar to that achieved by the conventional regimen. The new regimen thus reduces the cost of treatment obviously.
