Objective To determine the effects of a 12-week aerobic exercise program on brachial-ankle pulse wave velocity ( baPWV) in sedentary and under-exercised healthy older adults. Methods A total of 35 sedentary and unfit but healthy older adults with mean age of 74.7 years were randomly assigned to a progressively increased intensity aerobic exercise group ( n = 17) or a control group ( n = 18). The exercise group performed aerobic exercise 3 times each week for 12 weeks. The control group didn't participate in the exercise program. Heart rate,blood pressure and baPWV were evaluated at admission to the aerobic exercise program and at the end of the 12 weeks in both groups. Results The mean baPWV in the aerobic exercise group decreased from 15.88 m/s to 14.62 m/s after exercise, a significant reduction. Blood pressure in the exercise group showed a decrease which was not significant. No significant improvement was identified in the control group. Conclusions Only 12 weeks of aerobic exercise with progressively increased intensity can improve arterial elasticity in sedentary and unfit older adults.

Objective To estimate the value of neck circumference in diagnosis of metabolic syndrome. Methods We analyzed the neck circumference of 523 volunteers and the occurrence of metabolic syndrome among them. Then we updated and revalued their data after follow-up for 1.5 years, meanwhile, we evaulated the value of Body Mass Index (BMI) and neck circumference in predicting metabolic syndrome. Results The increase of neck circumference was closely related to the occurrence of metabolic syndrome , and this tendency continued in the follow-up. Compared with BMI , neck circumference was sensitive in identifying the patients of metabolic syndrome. Conclusion Neck circumference has great value in diagnosis and treatment of metabolic syndrome.

Objective To evaluate the feasibility,safety,post-operative short and long-term outcomes of laparoscopic-assisted D2 radical distal gastrectomy in treating advanced gastric carcinoma without serosal invasion.Method From May 2007 to May 2013,54 cases of advanced gastric antral cancer without serosal invasion underwent laparoscopic-assisted D2 radical distal gastrectomy (laparoscopic group),54 demographically and pathologically-matched cases undergoing open surgery served as control.The surgical risk,post-operative recovery and follow-up results were compared.Result Surgery was successful in all patients.The mean operation time in laparoscopic group and open group was (168 ± 31) mins and (157 ±20) min respectively,the difference was significant (t =2.237,P =0.027) ; Intra-operative blood loss was (151 ± 56) ml and (213 ± 86) ml (t =4.45,P =0) ; Post-operative intestinal function recovery time was (2.7 ± 0.7) d and (3.4 ± 0.5) d (t =5.4,P =0) ; Lymph node dissection number was (26.4 ± 4.2) and (24.8 ±5.2) (t =1.769,P=0.08).Post-operative complication rate was 4％ and 11％ (P =0.142).There was no perioperative mortality in either group.Post-operative pathological stage of Ⅰ B,Ⅱ A,Ⅱ B,ⅢA was 8,17,24,5 cases in laparoscopic group and 9,14,23,8 cases in open surgery group.108 cases were followed up from 7 to 79 months.In laparoscopic group,8 cases had local recurrence or distal mestastasis,and 4 cases died from tumor; In open group,9 cases had local recurrence or distal mestastasis,and 6 cases died from tumor.Conclusions Laparoscopic-assisted D2 radical distal gastrectomy in treating advanced gastric cancer without serosal invasion is feasible,safe and advantageous in minimal invasion and rapid recovery,with good short and long-term outcomes.

The aquaporins (AQPs) are small, integral-membrane proteins which selectively transport water across cell plasma membranes. AQPs are over-expressed in tumor cells of different origins, particularly aggressive tumors. AQPs-expressing cancer cells show enhanced migration in vitro and greater local tumor invasion, tumor cell extrava-sations, and metastases in vivo. AQPs inhibition will provide a help for tumor therapy.

The balanced moisture absorption rate of the powders were 14.87%, 14.39%, and 15.38%, respectively, whereas the granules were 10.75%, 10.29%, and 11.13%, respectively. Conclusion The selected excipients can effectively reduce the hygroscopic rate of the Yixinshu Capsules, and its granules can promote the moisture resistance of Yixinshu Capsules.

Objective To study miRNA expression differences in ovalbumin(OVA)- induced murine asthma models of mice and mast cells stimulated by inflammatory cytokines stimulation,and to better understand asthma deve-lopment so as to provide potential target for its prevention and treatment. Methods OVA - induced murine asthma models were validated by detecting cells in bronchoalveolar lavage fluid(BALF)and histopathology. And miRNA ex-pression differences in the lung tissues between the model group and the normal control group were detected by real -time polymerose chain reaction PCR . After tumor necrosis factor - α(TNF - α),interleukin 12(IL - 12)stimulation, miRNA expression differences in murine mast cells P815 were detected. Results The number of total cells and eosino-phil cells both increased in BALF of the model group[(12. 8 ± 2. 2)x 107 / L vs(5. 6 ± 2. 5)x 107 / L,t = 4. 760,P ﹤0. 05;(6. 6 ± 1. 9)x 107 / L vs(0. 8 ± 0. 8)x 107 / L,t = 8. 068,P ﹤ 0. 05]. In addition,histopathology showed more inflammatory cell infiltration in the model group than that in the normal control group,indicating that the models were validated. The expression of miRNA - 155 was up - regulated approximately 5. 0 - fold in the lung tissues of the model group(P ﹤ 0. 05),while miRNA - 192 showed no differences compared with the controls. After TNF - α and IL - 12 stimulated P815 mast cells,miRNA - 192 expressions in P815 were expression in P815 was up - regulated approximate-ly 1. 9 - fold and 1. 7 - fold after TNF - α and IL - 12 stimulation,respectively(P ﹤ 0. 05). Conclusions It is conclu-ded that miRNAs are differentially expressed in the presence of OVA - induced murint asthma models and mast cells stimulated by inflammatory cytokines. These differentially expressed miRNAs may regulate the function of mast cells and involved in the pathogenesis of asthma.

Objective To evaluate the diabetes self-management program based on Chinese local patients in Nanjing community. Methods From April 2014 to June 2014, diabetes patients were recruited through health records system screening in the community health service centers, letter invitation, poster announcements at communities, and telephone notification. A total of 53 self-management groups were established. Nanjing diabetes self-management program included six 1-1.5 hours sessions scheduled on consecutive weeks, based on the blueprint of Shanghai Chronic Disease Self-Management Program (CDSMP) developed at Stanford University. Baseline and three-month later interviews were conducted respectively. Results A total of 636 patients were recruited and agreed to enter CDSMP; 603 completed the 6-session activities, with the response rate being 94.8%.
