Objective To investigate the effects of ulinastatin on the expression of NF-κB in lung tissues during limb ischemia-reperfusion(I/R) in rats.Methods Forty-eight male SD rats weighing 230-260 g were randomly divided into 3 groups (n=16 each):sham operation group (group S);I/R group; ulinastatin group (group U).A rat model of lung injury induced by I/R of hind limbs which was produced by occlusion of the bilateral femoral arteries for 2 h followed by reperfusion was established.The rats were sacrificed at 2 and 4 h of reperfusion(8 rats at each time point) and the lung tissues removed for determination of NF-κB expression (by immuno-histochemistry) and microscopic examination.W/D lung weight ratio was calculated.Results W/D lung weight ratio was significantly increased and NF-κB expression was up-regulated in group I/R compared with group S(P＜ 0.05). W/D lung weight ratio was significantly decreased and NF-κB expression was down-regulated in group U compared with group I/R (P＜0.05). The lung injury induced by I/R was reduced in group U compared with group I/R. Conclusion Ulinastatin can reduce the lung injury induced by limb I/R by down-regulating the expression of NF-κB in rat lung tissues.

Objective To investigate the effect of tigecycline on serum procalcitonin and its efficacy in the treatment of elderly chronic obstructive pulmonary disease (COPD) and nosocomial infection. Methods 82 elderly patients with COPD with nosocomial infection were selected and randomly divided into two groups with 41 cases of each group, the control group received routine treatment combined with cefoperazone and sulbactam, and the experimental group received routine treatment combined with tigecycline, 2 weeks for a course of treatment. The serum inflammatory factors and laboratory related indexes, clinical efficacy and bacterial clearance were compared after the treatment. Results Compared with control group, the levels of serum high-sensitivity C-reactive protein (hs-CRP), interluekin 6(IL-6) and tumor necrosis factorα(TNF-α) were significantly lower, and the serum levels of PCT and NO were lower(P < 0.05). The total efficacy of experimental group was 90.24%, which was higher than 70.73% in control group (P<0.05). The bacterial clearance rate in the control group was 63.42%, which was lower than the experimental group of 87.80% (P < 0.05). Conclusion Tigecycline in the treatment of COPD and nosocomial infection in elderly patients is curative effective and it can reduce the serum levels of PCT, NO and inflammatory factors with high safety.

Objective To investigate the expression of neuronal nitric oxide synthase(nNOS) and heme oxygenase-2(HO-2) in colon after stress in rats. Methods Water immersion-restraint stress(WRS) model was performed.The expressions of nNOS and HO-2 in colon of rats were examined by immunohistochemical staining and analysed by image analysis system. Results In control group rat,nNOS immune-positive substance mostly expressed in neurons of submucous plexus and myenteric plexus and HO-2 mostly expressed in lamina propria mucosal muscles of colon mucosa,circular muscles of colon and the endothelium and smooth muscle cells of submucosal bloodvessels.Compared with control group rat,the average gray value of nNOS positive neurons in submucous plexus and myenteric plexus and the average number of nNOS positive neurons increased significantly,the average gray value of HO-2 positive mucosal muscles and the positive unit(PU) of circular muscles increased in stress group rat,moreover,nNOS expression in mucosal epithelial cells and lamina propria lymphocytes and HO-2 expression in some large intestinal glands were observed.Compared with stress group rat,the average gray value of nNOS positive neurons in submucous plexus and myenteric plexus and the average number of nNOS positive neurons decreased in stress +L-NAME group,the average gray value of HO-2 positive mucosal muscles and the PU of circular muscles decreased in stress +ZnPP group.Conclusion Both nitric oxide(NO) and carbon monoxide(CO) are important gaseous signal molecules and neurotransmitters in colon of rats and may play a cooperative role in colonic functional disorder induced by WRS.

Objective:This study analyzed how the 10 Global Conferences on Health Promotion have played a significant role in shaping and promoting a worldwide consensus and actions on health promotion,effectively addressing diverse health challenges that evolved over different periods. Methods:The textual analysis method was used in this study and text encoding was conducted to systematically examine the declarations and reports presented by the 10 Global Conferences on Health Promotion held during 1986-2021.We summarized the themes and key achievements,and key vocabulary in the conference declarations was extracted and analyzed to construct the global health promotion consensus and actions. Results:The fundamental principles of the conferences are to foster consensus and initiate actions in the realm of health promotion on a global scale.The primary purpose and goal are to promote health from regional to global.Significantly,our findings highlight a transition in the primary actors driving health promotion.It underscores a shift in health promotion from being driven primarily by organizations like the World Health Organization,governments,and international bodies,to a more inclusive approach involving non-governmental organizations and the general public.This development implies that health promotion has evolved into a collective global en-deavor,demanding the proactive involvement of various stakeholders,and forging new alliances in public health.Meanwhile,the coronavirus disease 2019(COVID-19)pandemic has further shaped the landscape of health pro-motion,underscoring the need for intensified focus on areas including disease prevention,health education,and the integration of digital health technologies,and emphasizing the importance of a multidimensional,responsive approach in public health initiatives. Conclusions:Sustained collaboration and innovative strategies are pivotal to advancing health promotion globally.Countries,together with public and private entities,should intensify cooperation.Multisectoral collaboration among partners such as healthcare,education,social security,and the industry is vital for health promotion and achieving global health goals.

With an increasing proportion of sedentary lifestyle related chronic diseases, an efficient way to help fight the growing world epidemic of non-communicable diseases (NCDs) and promote public health in a fast-changing world is urgently needed. Exercise and medicine science have played an important role in prevention and control of NCDs. However, the current status and future development directions regarding the integration of exercise science and medicine (IESM) in China have not been well discussed. During 2017 Belt and Road Initiative Global Health International Congress & 2017 Chinese Preventive Medicine Association-Chinese Society on Global Health Annual Meeting, Xi'an Jiaotong University Global Health Institute, and the Integration of Sport and Medicine Innovation Research Center, China Institute of Sport Science organized the IESM Forum on September 27. Six leaders and experts from China and abroad presented excellent research reports in the IESM Forum from several aspects. Experts reached a consensus at the end of their discussions that, in the near future, the IESM will be a key part of a sustainable health care system and as such should contribute to prosperity in China and around the world. However, Abstract compared with European, American and Japanese universities, the development of the IESM in China is in its early stages with huge development potential.
