Objective .To evaluate the role of cystatin c in the risk judgement of coronary artery disease. Methods 77 patients with coronary artery disease were involved in the study.They were divided into two groups:Group 1 were patients with angiographically diagnosed coronary artery disease ( CAD) with their first acute coronary syndrome ( n=55);Group 2 were patients who had clinically diagnosed coronary disease but were negative on angiog-raphy ( n=22) .Serum Cys C levels in the two groups and the correlation to CAD were analyzed.Results Serum Cys C levels in patients of Group 1 were higher than that of Group 2 [(1.23 ±1.07)mg/L vs.(0.71 ±0.32)mg/L,P=0.002],but no significant difference was found between the two groups in crea levels [(123.76 ±80.44)μmmol/L vs.(117.63 ±65.43)μmmol/L,P=0.230].A ROC analysis revealed that there was a significantly higher risk of ACS above a cystatin c level of 0.875mg/mL (sensitivity:84.3%,specificity:38.8%).A similar analysis carried out for eGFR did not find any significant cut-off points above which risk of ACS was higher.Conclusion The data showed that a high level of cystatin c level is a risk factor for ACS.This could play an important role in the early diag-nosis and prevention of adverse cardiovascular events.

Lipocalin-2 is an adipocytokine secreted mainly by adipose tissue. Increasing lines of evidence suggest that lipocalin-2 is an inflammatory factor associated with insulin resistence, obesity and its complications. The precise mechanism of the development of obesity-related disorders induced by lipocalin-2 is not very clear, however, it may be a useful target in drug therapy for obesity-related metabolic and cardiovascular diseases.

Methamphetamine (MA) is a highly addictive psychostimulant that has effects on central nervous system.Chronic MA useis linked to serious neurotoxic effects and ultimately cognitive impairments, thus understanding the effect of chronic MA use on cognitive function can improve the treatment of MA abusers and reduce MA relapse. In the present study, we summarized the main results of animal experiments, neuropsychological studies and brain imaging studies on MA abuse and cognitive impairment, which may provide the basis for future research and clinical treatment.

The current therapeutic strategies for ischemic stroke are more limited. In the field of cell therapy, a series of basic and clinical research have suggested that bone marrow mesenchymal stem cells have therapeutic effect on ischemic stroke. This article mainly reviews the biological characteristics of bone marrow mesenchymal stem cells and the latest progresses in research on the treatment of ischemic stroke.

Objective To analyze the relationship between insulin resistance (IR) and left ventricular hypertrophy ( LVH ) in patients with early chronic kidney disease ( CKD ). Methods Homeostatic model method was used for detecting insulin resistance index (Homa-IR) in 108 patients with early CKD and 25 normal healthy cases, and the other clinical data such as Hb, creatinine clearance rate (Ccr) , parathyroid hormone (PTH) , ambulatory blood pressure monitoring ( ABPM ) data, including day average systolic blood pressure (dSBP), day average diastolic blood pressure (dDBP), night average systolic blood pressure ( nSBP) , night average diastolic blood pressure ( nDBP) , 24-hour mean systolic blood pressure (mSBP), 24-hour mean diastolic blood pressure (mDBP), decline in the percentage of diastolic blood pressure at night (nDPD) and decline in the percentage of systolic blood pressure at night (nDPS) were also measured. Echocardiography was used for measuring LVH relevant data, and left ventricular mass index (LVMI) was calculated. Then, the relationship between LVH and IR and other clinical data were analyzed retrospectively. Results IR existed in early CKD patients. With the decline of Ccr, both the value of Homa-IR and the incidence of IR increased significantly (both P < 0. 05). LVH existed in early CKD patients and with the decline of Ccr, both LVMI value and the incidence of LVH increased significantly (both P <0. 01). Compared with the non-IR group, the IR group had higher LVMI value (P<0. 05) and higher incidence of LVH (P<0. 01). Compared with the non-LVH group, the LVH group had higher levels of Fins, 2hPG, Homa-IR (all P <0. 05), and higher incidence of IR (P <0. 01). The LVH group had significant lower levels of Ccr, Hb and nDPD (all P <0. 05) , higher levels of dSBP, dDBP, nSBP, nDBP, mSBP, mDBP and PTH (all P<0.05) than the non-LVH group. LVMI had significant positive correlations with 2hPG, Fins, Homa-IR, dSBP, nSBP, mSBP and PTH (r = 0.255, 0.373, 0.376,0.222,0.199,0.225,0.221,0.246, respectively; all P<0.05), but significant negative correlations with Hb and Ccr (r = -0.588,-0.313, respectively; both P<0.01). Multi-factor regression analysis showed that Hb, Homa-IR, and Ccr entered the regression equation (y = 167. 106 - 0. 755x_1 + 0. 250x_2 +0.322x_3, y = LVMI; 167. 106 = constant, t = 12. 138, P =0.000; x_1 =Hb, t= -6.800, P = 0. 000; x_2 = Homa-IR, t = 3. 229, P = 0. 002; x_3 = Ccr, t = 2. 898, P = 0. 005). Conclusion IR existed in early CKD patients and become more severe with the decline of renal function. IR had a significant correlation with LVH, and it may be an important risk factor for the development of LVH. Besides, both anemia and decline of renal function are also associated with LVH.

OBJECTIVE:To investigate the therapeutic efficacy and safety of Posterior pituitary injection combined with Ulina-station for injection in the treatment of severe lung contusion. METHODS:In retrospective study,60 patients with severe lung con-tusion in our hospital from Jan. 2015 to May 2016 were divided into control group and observation group according to therapy plan,with 30 cases in each group. Control group was given Ulinastation for injection 100 thousand U+0.9% Sodium chloride injec-tion 100 mL,ivgtt,bid. Observation group was additionally given Posterior pituitary injection 6 U+0.9% Sodium chloride injection 49 mL,intravenous pumping (initial rate was 0.008 U/min,adjusted to ≤0.04 U/min),bid,on the basis of control group. Both groups were treated for 1 week. The respiratory frequency,simple score of pulmonary contusion,chest X-ray score,the levels of arterial blood gas indexes(PaO2,PaCO2,SaO2,PO2/FiO2)and inflammation indexes(IL-2,IL-6,IL-10,hs-CRP,TNF-α)before and after treatment as well as clinical efficacy were observed in 2 groups. The occurrence of ADR was recorded. RESULTS:Before treatment,there was no statistical significance in respiratory frequency,simple score of pulmonary contusion,chest X-ray score, the levels of arterial blood gas index or inflammation indexes between 2 groups(P>0.05). After treatment,respiratory frequency, simple score of pulmonary contusion,chest X-ray score,and the levels of IL-6,hs-CRP,TNF-αin 2 groups were decreased signif-icantly,and the observation group was significantly lower than the control group,with statistical significance(P<0.05). The lev-els of PaO2,PaCO2,SaO2,PO2/FiO2,IL-2 and IL-10 in 2 groups were increased significantly,and the observation group was sig-nificantly higher than the control group,with statistical significance (P<0.05). Total response rate of observation group (100%) was significantly higher than that of control group(86.67%),with statistical significance(P<0.05). The incidence of ADR in con-trol group(13.33%)was significantly higher than observation group(6.67%),with statistical significance(P<0.05). CONCLU-SIONS:Posterior pituitary injection combined with Ulinastatin for injection show good therapeutic efficacy for severe lung contu-sion and effectively inhibit inflammatory reaction with good safety.

Objective To investigate the genotoxicity of heavy rare-earth holmium to bone-marrow cells of mice.Methods Kunming mice were randomly divided into six groups and were given holmium-trioxide-HCl by gavage at several doses of 0,10,20,40,80 and 160 mg/kg bw respectively one time a day for two days;other Kunming mice were randomly divided into 3 groups and holmium nitrate was given i.p.at doses of 10,40 and 80 mg/kg bw respectively one time a day for two days.24 hours after the last treatment,the bone-marrow cells of thighbone were collected for micronuclei analysis and single cell gel electrophoresis (SCGE).Results Frequencies of micronuclei were increased by the 2 kinds of holmium solutions at the dosage from 10 to 80 mg/kg bw with a dose-effect relationship,but at the dose of 160 mg/kg bw,it was lower than the negative control.In SCGE,the average tail length increased significantly (P
