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 examine the impact of diabetic foot patients′ negative emotion on the caregiver′quality of life. Methods Totally 100 pairs of diabetic foot patients and their caregivers were investigated using convenience sampling method. Results The incidence of anxiety, depression of hospitalized patients with diabetic foot was 41.5% (23/200), 44.0% (88/200) respectively. Pearson correlation analysis showed that anxiety score were negatively correlated with caregivers′ quality of life except for mental health dimension, physical pain dimension and the total score of physical health, mental health and the MOS item Short from Health Survey (SF-36) (r=-0.471--0.117, P<0.05), and depression score were negatively correlated with caregivers′ quality of life except for physical pain dimension and the total score of physical health, mental health and SF-36(r=-0.519--0.220, P<0.05). Multiple regression analysis indicated that caregivers educational level, provided support, social support , relationship with patients, self-evaluation of health, live together time with patient, patient care burden, caregivers gender, depression score, patient age, diabetic foot Wagner grade were the influence factors of the caregiver′ quality of life. Conclusions Diabetic foot patients′ negative emotion has an important impact on caregiver′quality of life, we can improve the quality of life of patients and their caregivers by reducing the negative mood of patients with diabetic foot.

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.

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.

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).

Objective To investigate the influence of fear of hypoglycemia on the compliance of diabetes patients.Methods A total of 201 diabetes inpatients with hypoglycemia in four first-class hospital of grade three in Ji'nan were selected by convenience sampling method and investigated by General Information Questionnaire,Chinese version of Hypoglycemia Fear Survey Ⅱ-Worry Scale and Diabetes Treatment Compliance Scale.And carrid on the correlation analysis and the multiple linear regression analysis.Results The scores of fear of hypoglycemia was 3-33 points,the median score was 12 points(interquartile range,10-15 points).The score of treatment compliance was 23-55(35.90±5.84)points.Spearman correlation analysis showed that fear of hypoglycemia score were negative correlated with treatment compliance score,drug,diet,exercise dimensions(r=-0.467-0.288),and it was positively correlated with self monitoring dimension(r=0.259),the difference was statistically significant(P＜0.01),it was not associated with periodic inspection dimension.Multiple linear regression analysis showed that the economic income,occupation,whether to participate in health education of diabetes mellitus,glycosylated hemoglobin,fear of hypoglycemia were the influence factors of treatment compliance.Conclusions Diabetes patients'fear of hypoglycemia can influence treatment compliance.medical staff should pay attention to and take effective measures to reduce their fear of hypoglycemia and improve treatment compliance.

Objective To discuss the therapy for acetabular comminuted fractur e combined with compressive defects. Methods From July 1997 to February 2005, 43 cases of comminuted acetabular fracture combined with compressive defect were t reated. 25 cases were obsolete, 16 fresh, and 2 malformed (90 days after injury) . 34 cases were complicated fractures with defects, and 9 simple fractures with defects. The defect volumes ranged from 3 to 9 cm3, averaging 4.5 cm3. They were treated with ATMFS (acetabular tridimensional memory fixation system) to fixate the comminuted bone fragments tridimensionally. The modified acetabular approac h, reduction of acetabular comminuted articular face, anatomical reconstruction of posterior wall of acetabulum with autogenous ilium, autogenous and artificial bone implantation and bone wax isolation were used. The follow-ups lasted from 5 to 86 months, averaging 15.7 months. Results 31 cases achieved anatomical red uction by filling up the compressive defects. 12 cases were treated by anatomica l reconstruction of posterior wall. On average, 5.3 months after operation, the injured hip joint was as good as the healthy one in 40 cases. Ischemia necrosis of femoral head occurred in 1 case, and 2 cases experienced heterotopic ossifica tion with ischemia necrosis of femoral head which led to osseous fusion of hip j oint. Conclusion The new methods for treatment of acetabular fractures with comp ressive defects elevate the reduction rate of acetabulum and femoral head, and a re effective for the functional recovery of hip joint.
