Objective To evaluate the effects of N-acetycysteine on the expression of caveolin-3 (Cav-3) during myocardial ischemia-reperfusion (I/R) in diabetic rats.Methods Twenty-four pathogenfree healthy adult male Sprague-Dawley rats,weighing 230-270 g,were divided into 3 groups (n =8 each) using a random number table:myocardial I/R group (group I/R),diabetes mellitus plus myocardial I/R group (group D) and N-acetycysteine group (group NAC).Diabetes mellitus was induced by injection of streptozotocin 60 mg/kg via the tail vein and confirmed by blood glucose ≥ 16.7 mmol/L 3 days later.At 1 week after successful establishment of the model,N-acetycysteine 1.5 g · kg-1 · d-1 was injected through a gastric tube into stomach for 4 consecutive weeks in group NAC,and the equal volume of normal saline was given for 4 consecutive weeks in I/R and D groups.Myocardial I/R was then induced by 30 min ligation of the left anterior descending branch of the coronary artery followed by 2 h of reperfusion.At the end of reperfusion,the myocardial infarct size was determined by triphenyl tetrazolium chloride staining,the levels of serum creatine kinase-MB (CK-MB) and 15-F2t-Isoprostane were measured by enzyme-linked immunosorbent assay,and the expression of myocardial Cav-3,Akt,phosphor-Akt (p-Akt),endothelial nitric oxide synthase (eNOS) and phosphor-eNOS (p-eNOS) was detected by Western blot.Results Compared with group I/R,the myocardial infarct size and levels of serum CK-MB and 15-F2t-Isoprostane were significantly increased,and the myocardial Cav-3,p-Akt and p-eNOS expression and NO level were decreased in group D (P＜0.05).Compared with group D,the myocardial infarct size and levels of serum CK-MB and 15-F2t-Isoprostane were significantly decreased,and the myocardial Car-3,p-Akt and p-eNOS expression and NO level were increased in group NAC (P＜0.05).Conclusion N-acetycystein can activate Akt/eNOS/NO signaling pathway through up-regulating myocardial Cav-3 expression,thus reducing myocardial I/R injury in diabetic rats.

To summarize the causes of relocation stress in family members of patients transferred from ICU.Based on muhidisciplinary collaboration,stress prevention before transfer and stress intervention after transfer were implemented.For thirty family members of patients in our group,their level of relocation stress 7d after transfer was low.

Objective: To evaluate the long term efficacy of treating the primary dysmenorrhea of cold-damp stagnation type by Acupuncture of Liji therapy. Methods: In this study, a total of 76 cases of primary dysmenorrhea of cold-damp coagulation type were randomly divided into the acupuncture of Liji therapy group, and the body acupuncture group, with38 cases in each group. Both groups were continuously treated 3 menstrual cycles, and followed up in the third and six menstrual cycles after the end of the treatment. Visual analogue scale for abdominal pain and Dysmenorrhea Symptoms scale were used as therapeutic indexes. Remove shedding cases, the long-term effects and scores of the 2 groups were compared. Besides, untoward and side effects needed to be recorded. Results: There were 2 cases lost in the acupuncture ofLiji therapy group and 1 cases in the body acupuncture group. After treatment, The clinical comprehensive efficacy of acupuncture ofLiji therapy group was better than that of body acupuncture group (P ＜ 0. 05) . Both groups of VAS scores and dysmenorrhea symptom scores were decreased to different degrees during treatment and follow-up period (P ＜ 0.05) .The follow-up data of the body acupuncture group after six menstrual cycles were higher than that of the third menstrual cycles after treatment. Compared with the two groups, the acupuncture of Liji therapy group was superior to the body acupuncture group during the third menstrual cycles follow-up (P ＜ 0.05) and six menstrual cycles follow-up (P ＜ 0.01) .The treatment satisfaction of acupuncture of Liji therapy and body acupuncture was 91.67％ and 72.97％. There were no adverse reactions in the two groups during the study period. Conclusion: Acupuncture of Liji therapy can effectively relieve dysmenorrhea symptoms and the general discomfort caused by dysmenorrhea, the long-term effect is stable and durable. primary dysmenorrhea of cold-damp stagnation type with acupuncture of Liji therapy has definitely long term curative effect. In addition, the treatment of patients with acupuncture of Liji therapy is more satisfactory, it is worthy of cilnlcal application.
