Hypoxic preconditioning (HPC) refers to exposure of organisms, systems, organs, tissues or cells to moderate hypoxia/ischemia that is able to result in a resistance to subsequent severe hypoxia/ischemia in tissues and cells. The effects exerted by HPC are well documented. The original local in situ (LiHPC) is now broadened to remote ectopic organs-tissues (ReHPC) and extended crossly to cross pluripotential HPC(CpHPC) induced by a variety of stresses other than hypoxia/ischemia, including cancer, for example. We developed a unique animal model of repetitive autohypoxia in adult mice, and studied systematically on the effects and mechanisms of HPC on the model in our laboratory since the early 1960s. The tolerances to hypoxia and protection from injury increased significantly in this model. The adult mice behave like hypoxia-intolerant mammalian newborns and hypoxia-tolerant adult animals during their exposure to repetitive autohypoxia. The overall energy supply and demand decreased, the microorganization of the brain maintained and the spacial learning and memory ability improved but not impaired, the detrimental neurochemicals such as free radicals down-regulated and the beneficial neurochemicals such as adenosine(ADO) and antihypoxic gene(s)/factor(s) (AHGs/AHFs) up-regulated. Accordingly, we hypothesize that mechanisms for the tolerance/protective effects of HPC are fundamentally depending on energy saving and brain plasticity in particular. It is thought that these two major mechanisms are triggered by exposure to hypoxia/ischemia via oxygen sensing-transduction pathways and HIF-1 initiation cascades. We suggest that HPC is an intrinsic mechanism developed in biological evolution and is a novel potential strategy for fighting against hypoxia-ischemia and other stresses. Motivation of endogenous antihypoxic potential, activation of oxygen sensing--signal transduction systems and supplement of exogenous antihypoxic substances as well as development of HPC appliances and HPC medicines such as AHFs are encouraged based on our basic research on HPC. HPC may result in therapeutic augmentation of the endogenous cytoprotection in hypoxic-ischemic or suffering from other diseases' patients. Evolutionary consideration of HPC and clinical implications of HPC are both discussed to guide future research. The product of AHF is expected to be one of the most effective first aid medicines to rescue patients in critical condition. HPC is beginning to be used in surgery and is expected to be developed into a feasible adaptive medicine in the near future.

Objective To explore the mechanisms of ischemia-reperfasion(I/R)injury of the bile duet and the effect of Atomolan on Isehemia-reperfusion injury of the bile duct in liver transplantation.Methods Pathological changes of the bile duct cells in three groups of rat liver transplantation model were observed through light microscope.And the effective protection of Atomolan against ischemia-repeffusion injury was observed.Results In ischemia-reperfusion group,the injury of bile duct cells were more serious,the level of ALT,AST and γ-glutamyhransferase elevated higher,oxygen free radical generated more,and the apoptosis of bile duct ceils appeared more,compared with Atomolan pretreatment.Conclusion The injury in bile duct cells is more serious than that in hepatoeyte in I/R injury.Atomolan can provide effective protection against liver Ischemia-reperfusion injury.The mechanisms may be through depress the production of oxygen free radical and decrease the apoptosis of bile duct cells.

OBJECTIVE To investigate the distribution and antimicrobial resistance of Acinetobacter baumannii infection in the elderly patients in our hospital. METHODS One hundred and eighty-four strains of A. baumannii isolated from elderly patients with infection from Jun 2001 to Apr 2005 were collected and antimicrobial susceptibility test was performed. RESULTS All strains of A. baumannii were from sputum, urine, pus, etc; the resistance of the strains to the third generation cephalosporin, ciprofloxacin and ofloxacin was all more than 50.0% ; the resistance rate to imipenem was the lowest(2.2%), followed by amikacin (37.5%)and ampicillin/ sulbactam (39.7%), and the resistant rate to ampicillin was the highest( 83.2% ). CONCLUSIONS The antimicrobial resistance of A. baumannii in the elderly patients is high, the antibiotic treatment must depend on antimicrobial susceptibility test.

AIM: To assay the pattern of thyroid hormone alternations in systemic inflammatory response syndrome (SIRS) patients. METHODS: 50 SIRS patients were enrolled, divided into two groups as to whether they got MODS. Thyroid hormone measurements were taken, including total T_3 (TT_3), total T_4 (TT_4), free T_3 (FT_3), free T_4 (FT_4) and TSH. The acute physiology and chronic health evaluationⅡ (APACHEⅡ) score was calculated according to clinical data. Outcome (recovery or deterioration) was recorded, as well as the length of time from the onset of SIRS to the day when thyroid hormones were measured (the duration of SIRS). RESULTS: Euthyroid sick syndrome (ESS) was presented in 45 cases. TT_3 level was negatively correlated with APACHEⅡscore (r=-0.330, P0.05). CONCLUSION: SIRS patients has high possibility to get ESS, which happens more frequently and severely in MODS patients. With the persistence and aggravation of SIRS, there is a progression of thyroid hormone reduction.

Objective To investigate the clinical results and prognosis between proximal and total gastrectomy in proximal advanced gastric cancer.Methods The clinicopathological data of 221 patients with proximal advanced gastric cancer who undcrwent radical gastrectomy were retrospectively analyzed.82 patients and 139 patients underwent proximal and total gastrectomy respectively.The number of dessected lymph nodes,postoperative complications and mortality were compared.Kaplan-Meier survival rate curves and Log-rank test were drawn and compared.Results A total of 1 411 (11-34) and 3 345 (14-35) lymph nodes were harvested from the surgical specimens of 82 and 139 patients with proximal and total gastrectomy respectively,the average number of harvested lymph nodes was 17 ± 11 and 24 ± 10 (t =2.586,P ＜0.05).The overall complications in proximal gastrectomy were higher than total gastrectomy (73.2％ vs.30.2％,x2 =38.291,P ＜0.01).The ratio of functional delayed gastric emptying,anastomotic leakage and stenosis,reflux esophagitis in proximal gastrectomy patients was higher than total gastrectomy.The survival rate in proximal gastrectomy were lower than total gastrectomy in proximal advanced gastric cancer (P ＜0.01).Conclusion Total gastrectomy is recommended for proximal advanced gastric cancer.

Objective To study and analyze of entecavir dispersible tablets on the treatment of patients with decompensated hepatitis B cirrhosis. Methods From February 2014 to September 2016, 100 patients with decompensated hepatitis B cirrhosis were randomly divided into the control group and the experimental group, 50 patients in each group. The control group were received routine treatment, while the experimental group were received entecavir dispersible tablets treatment on the basis of conventional treatment. The therapeutic effects in the two groups were compared and analyzed. Results The effective rate in the experimental group was 92.0%, and 70.0% in the control group. The effective rate in the experimental group was significantly higher than that in the control group, the difference has statistically significant (P<0.05). The Child-pugh score in the experimental group was (6.12±1.43) points, and the score in the control group was (7.23±1.95) points. The score in the control group was significantly higher than that in the experimental group, with statistical difference (P<0.05). The negative rate of HBeAg in the experimental group was 22.0%, while 86% in the control group the difference has statistically significant (P<0.05). Conclusion The clinical effect is better which entecavir dispersible tablets is used in the treatment of the patients with decompensated hepatitis B cirrhosis, which can improve the treatment efficiency to a great extent, recover the liver function, has the further promotion and application significance.
