Objective To observe the association between adiponectin gene polymorphism, serum adiponectin lev-els with the incidence of coronary artery disease (CAD) and the severity of coronary artery stenosis in patients with essential hypertension (EH). Methods A total of 414 patients with EH (234 cases with CAD and 180 cases without CAD) and 185 control subjects were recruited in this study. Serum adiponectin levels were measured by enzyme-linked immunosorbent as-say (ELISA). Adiponectin single-nucleotide polymorphisms rs266729,rs7649121,rs1501299 and rs3774262 were geno-typed by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP). Results Serum adiponectin levels were significantly lower in EH with CAD group than those in control group and EH without CAD group. Adiponectin SNP rs7649121 AT genotype reduced the risk of CAD compared with AA genotype (adjusted OR=0.566,95%CI 0.346-0.925,P=0.023). Logistic regression analysis showed that age and LDL-C were risk factors of CAD, and adiponectin was the protective factor for CAD in EH patients. The severity of coronary artery stenosis was negatively related to the level of adipo-nectin. Adiponectin levels were not affected by the adiponectin gene polymorphism. Conclusion The decreased serum adi-ponectin level was the independent risk factor for CAD in EH patients, which was negatively related to the severity of coro-nary artery stenosis. Adiponectin SNP rs7649121 may contribute to the risk factors of CAD in EH patients.

The paper is to report the establishment of a method for quickly evaluating compatibility of Chinese medicines injections. Isothermal titration calorimetry (ITC) was used to evaluate compatibility of Yiqifumai (YQFM) and vitamin C injection (Vc)/5% glucose injection (5% GS). The diversification of Gibbs free energy (deltaG), enthalpy (deltaH) and entropy (deltaS) were used to decide reaction types of colliquefaction procedures of different injections. The reactive profiles were used to determine signs and quantity of heat. And high performance liquid chromatography (HPLC) was used as a supportive method for ITC. Then, feasible binding sites were analyzed based on the information of spatial structures of major compositions. During the colliquefaction procedure of YQFM and Vc, [deltaH] > T[deltaS], so, the reaction is enthalpy-driving. And the reactive profile showed that a big deal of heat was given out during the procedure. Obviously, chemical reactions happened and the major compositions changed. On the other side, the reaction of YQFM mixed with 5% GS was entropy-driving, because [deltaH] < T[deltaS]. The reactive profile showed there was a little heat gave out. So, non-chemical reactions happened, and the major compositions did not change. The conformity existed between the results of ITC and HPLC. ITC could be used to evaluate the compatibility of Chinese medicines injections because of the advantages of ITC, such as real time, fast, sensitive and having more parameters.

Objective To observe the level of serum hepatocyte growth factor (HGF) in patients with impaired glucose tolerance (IGT). Methods Thirty patients with IGT (IGT group), 30 patients with type 2 diabetes mellitns (T2DM) (T2DM group) and 30 healthy controls (control group) were recruited for this study. Such indexes as HGF, fasting plasma glucose (FBG), postprandial plasma glucose (2hPG), glycosylated hemoglobin A1c( GHbA1c ), fasting insulin(FINS), systolic blood pressure(SBP), diastolic blood pressure (DBP) were examined and these related factors were analyzed. Results The levels of serum HGF in IGT group and T2DM group were higher than those in control group [(413.22 ± 102.48), (422.76 ± 126.77 ), ( 120.45 ± 25.11 ) ng/L, respectively ] (P < 0.05 ). There was no significant different between IGT group and T2DM group (P> 0.05). There was positive correlation between HGF and FBG (r = 0.326, P< 0.05 ). Multiple regression analysis indicated significant correlation between HGF and DBP (r = 4.730, P< 0.05). Conclusion Higher levels of HGF are found in IGT patients, which indicates that function of vascular endothelium is abnormal in this period.

A 57-year-old man was admitted to the hospital for a 7-year progressively spreading plaques involving the entire body surface, and multiple irregularly sized red nodules and infiltrated patches on the face, trunk and limbs. Histopathological examination showed pleomorphic tumor cells diffusely dis-persed throughout the dennis, giving an appearance of low proliferation. Some cells with cytoplasmic pro-cesses appeared multiangular in shape, lmmunohistochemically, tumor cells were negative for CDla or S-100, but positive for CD45, FXIIIa, CDl4, MHC- Ⅱ, CD68 and lysozyme with extracellular interstitial expression. Ultrastructurally, the cells exhibited cytoplasmic processes and irregularly sized nuclei; no Birbeck granules were observed. Vesicules of low electron-density were seen diffusely in cytoplasm and extracellular matrix. The case is herein diagnosed as cutaneous non-Langerhans cell histiocytosis, which presents with a chronically invasive clinical course. These cells may develop from immature dermal dendritic cells.

Objective To investigate the clinical value of the gated blood pool imaging phase analysis method in the evaluation of left ventricular mechanical synchronization in patients with chronic heart failure. Methods A total of 169 patients with chronic heart failure were enrolled in our study , using gated blood pool imaging phase analysis method to obtain left ventricular phase angle width ( PHB) and left ventricular phase angle standard deviation ( PSD) as evaluating left ventricular mechanical synchrony index; using tissue Doppler imaging (TDI) measurement of the standard deviation of systolic peak time(Ts-SD) of each segment by using the current prevailing 12 non-apical segments analysis method as evaluating left ventricular mechanical synchrony index, and parameters derived from both methods were compared. Results LVPHB was highly correlated with Ts-SD (r = 0. 83 ,P = 0. 000 ) . LVPSD was modestly correlated with Ts-SD ( r - 0. 69, P = 0. 000) . The ejection fraction measured by echocardiography was (42.93 ± 14. 89) % ,which was significantly higher than that measured by ERNA (39. 76 ± 17. 89)% (P <0. 01). Conclusions The evaluation of left ventricular mechanical synchrony in patients with chronic heart failure by the gated blood pool imaging can provide similar information with TDI, which can simultaneously measure two ventricular functions and get more accurate measurement of ejection fraction. Cardiac resynchronization therapy patients can be identified by combining two kinds of approaches, and cardiac resynchronization therapy responders could be improved as well. More patients with heart failure can benefit from cardiac resynchronization therapy therapy.
