Objective: To investigate constitutional and phys ical stamina status in soldiers with different adaption periods in Tibetan areas . Methods: Two hundred and eithty-two male soldiers from a barr acks at an elevation of 3 600 m were divided into 2 groups: the veteran group ( n=143) in Tibet for 1.45±0.22 year, and the recruit group (n=139) in Ti bet for 0.33±0.00 years. The test items included body weight, cirumference, st a nding long jump, chin-up, 100 m dash and 3 000 m jogging, all were evaluated ac cording to the national military standard, which were Comprehensive Evaluation o f Health in Troops, and Examination and Evaluation of the Physical Stamina of So ldiers. Results: The physical stamina indexes of both the vetera ns and the recruits were up to the national military norm on the whole, ranking as moderate. The veteran group showed no significant difference in standing long jump and 100 m dash,（P<0.05), but obvious lower level in chin-up and 3 00 0 m jogging（P<0.01）, compared with the national military norm. The recr ui t group showed significant lower level in chin-up, 100 m dash, 3 000 m jogging as compared with the national military norm（P<0.01）, and also significant lower level in chin-up and 3 000 m jogging （P<0.05 or P<0.01) as compa red with the veteran group. Conclusion: The physical stamina of both the veterans and the recruits meet the basic national military requirements , ranking as moderate. The soldiers who have been in service for over 1 year hav e better explosive force, but they need more tolerance and aerobic exercises. Th e newly recruited need more exercise to raise tolerance to the hypoxic environme nt in plateau areas so as to shorten the adaption time to high altitude.

AIM: To observe the effect of hemin on the expression of heme oxygenase-1(HO-1) in rat vascular smooth muscle cells(VSMCs). METHODS: Wistar rat aortic VSMCs were cultured in vitro and induced to proliferate by angiotensinⅡ(AngⅡ),hemin(a substrate and inducer of HO-1) and zinc protoporphyrin-Ⅸ(ZnPP,an inhibitor of HO-1)were added to induce and inhibit the expression of HO-1,respectively.The expression of HO-1 mRNA and protein were detected using reverse transcription polymerase chain reaction (RT-PCR)and Western blot,respectively. The relative amount of CO released into the media was quantitated as carbon monoxide hemoglobin(COHb)by enzyme-linked immunosorbent assay(ELISA),the proliferation of VSMCs was detected by MTT. RESULTS: The expression of HO-1 mRNA and protein in VSMCs and the amount of COHb in the media were increased significantly by hemin.Meanwhile the proliferation of VSMCs was suppressed markedly. CONCLUSION: The change of HO-1 mRNA and protein expression is the molecular base of the antiproliferation of endogenous CO .The HO-CO system might play a significant role in the development of cardiovascular diseases characterized by proliferation of VSMCs.

Objective To compare the predicting values for Prognosis among Global Risk Classification (GRS),Synergy Between Percutaneous Coronary Intervention With TAXUS and Cardiac Surgery (SYNTAX) score,the European System for Cardiac Operative Risk Evaluation (EuroSCORE) in patients who received stenting because of unprotected left main coronary artery (ULMCA) lesion.Methods Totally 105 successive elderly patients with ULMCA lesion who received stenting were divided into 2 groups:with and without main adverse cardiac events (MACE).The clinical and angiographic characteristics were analyzed and then compared among GRC,SYNTAX score and EuroSCORE.Results As compared with none MACE group,MACE group had higher EuroSCORE score (2.0±2.3 vs.6.5±2.9,t=8.18,P=0.002),and more trivessel disease and left main bifurcation lesion (x2 =8.96,6.96,P =0.011,P =0.008).High risk GRC showed more MACE than medium or low risk GRC [55.9％ (19/34) vs.20.5％(9/44),7.4％ (2/27),x2 =19.77,P=0.001].AUC(95％CI )of GRC,SYNTAX score and EuroSCORE were [0.821 (0.730-0.912),0.586(0.462-0.709) and 0.631 (0506-0.757)],respectively.Compared with SYNTAX score and EuroSCORE,GRC was superior in the MACE predicting value (Z=3.29,2.63,P＜0.01 or P＜0.05).

Sini decoction (SND), a classical traditional Chinese medicine emergency formula recorded in Shanghan Lun (Treatise on Febrile Diseases), which is composed of Aconiti Lateralis Preparata Radix, Glycyrrhizae Preparata Radix and Zingiberis Rhizoma. Modern clinical and pharmacological researches have shown that SND can protect the myocardium effectively during myocardial ischemia reperfusion injury (MI-RI). A myocardial ischemia reperfusion injury model of H9c2 cardiomyocytes in vitro has been established. Four groups, control group, MI-RI Model group, SND group and SND without Glycyrrhizae Radix group, were arranged. The livability, the level of LDH and CK activity in H9c2 cardiomyocytes in different groups were tested. By combining with principal components analysis (PCA), partial least squares discriminant analysis (PLS-DA), orthogonal partial least squares projection of latent structures-discriminant analysis (OPLS-DA), 17 biomarkers in extracellular fluid were identified and 15 of them were related to the pathway of biological processes. The results showed that the attenuate and synergistic mechanism between Aconiti Lateralis Praeparata Radix and Glycyrrhizae Radix for toxicity reduction was related with the glycolysis, lipid metabolism, citrate cycle and nitrogen metabolism of amino acids metabolism. The study proved the effect on H9c2 cardiomyocyte treated by MI-RI injury both SND group and SND without Glycyrrhizae Radix group, and compared with the SND without Glycyrrhizae Radix, the protective effect of myocardial ischemia reperfusion injury model of H9c2 cardiomyocyte from SND was stronger.

Objective To investigate the distribution of circadian typology of patients with type 2 diabetes mellitus (T2DM) and to analyze its consequent impact on glycemic control. Methods From January 2016 to June 2016, a total of 283 T2DM patients were interviewed in this study. Self designed questionnaire, Morningness-Eveningness Questionnaire (MEQ), Pittsburg Sleep Quality Index (PSQI) and Center for Epidemiological Survey-Depression Scale (CES-D) were used to collect information on diabetes history, circadian typology, sleep quality and depression. HbA1c and other biochemical indicators were determined. The glycemic control target was<7%. The 283 T2DM patients were divided into three groups:morning type group, evening type group and neither type group according to MEQ score. Results Of the 283 subjects, 97 (34.3%) were classified as morning type, 42 (14.8%) as evening type, and 144 (50.9%) as neither. Participants with evening type were younger, shorter diabetes duration, more depressive symptoms, higher perceived sleep debt, higher FBG and higher HbA1c than those with morning type. The binary Logistic regression analysis showed that HbAlc≥7%was associated with higher FBG, higher PSQI score, higher sleep debt, lower HDL-C, and lower MEQ scores (OR=0.189-2.904, all P<0.05). Conclusions Evening type was associated with higher HbA1c and poorer glycemic control in T2DM patients compared with morning type and may be one of the risk factors affecting glycemic control.

OBJECTIVETo assess any direct effect of extract of Paris polyphylla Simth (EPPS), a Chinese plant, on a cardiomyocyte subject to ischemia-reperfusion injury and to further elucidate its protective effect against myocardium ischemia on the cellular level.

METHODSNeonatal rat cardiomyocytes were isolated and subjected to an anoxia-reoxia injury simulating the ischemia-reperfusion injury in vivo in the presence or absence of EPPS or diltizem, a positive control. The lactate dehydrogenase (LDH) activities in culture supernatants and cell viabilities were analyzed using the enzymatic reaction kinetics monitoring-method and MTT method, respectively. Free intracellular calcium concentrations and activities of Na(+)-K(+) ATPase and Ca(2+) ATPase in cells were also measured with laser confocal microscopy and the inorganic phosphorus-transformation method, respectively.

RESULTSIn cardiomyocytes subject to anoxia-reoxia injury, EPPS at 50-400 mg/L showed a concentration-dependent inhibition on LDH leakage and maintenance of cell viability, and the effect was significant at 275 and 400 mg/L (both P<0.01). In addition, EPPS at 275 and 400 mg/L significantly inhibited the increase in intracellular free calcium (both P<0.01) as well as decreased the activities of Na(+)-K(+) ATPase and Ca(2+) ATPase (P<0.01, P<0.05).

CONCLUSIONSEPPS prevents anoxia-reoxia injury in neonatal rat cardiomyocytes in vitro by preservation of Na(+)-K(+) ATPase and Ca(2+) ATPase activities and inhibition of calcium overload. The direct protective effect on cardiomyocytes may be one of the key mechanisms that underlie the potential therapeutic benefit of EPPS against myocardium ischemia.
