Objective To evaluate the predictive value of serum presepsin (sCD14-ST) for septic myocardial depression (SMD) in patients with severe sepsis or septic shock.Methods This was a prospective cohort study.A total of 84 patients with severe sepsis or septic shock were monitored by pulse indicator continuous cardiac output (PiCCO) system and divided into myocardial depression group (cardiac function index [CFI]<4.1 L/min, n=37) and non-myocardial depression group (CFI≥4.1 L/min, n=47) according to cardiac function index (CFI).Left ventricular ejection fraction (LVEF) was measured by doppler echocardiography at admission.The patients were divided into survival group (n=40) and non-survival group (n=44) based on 28-day mortality.Serum sCD14-ST,B-type natriuretic peptide(BNP), tumor necrosis factor-α(TNF-α), cardiac troponin Ⅰ (cTnⅠ) levels and hemodynamic parameters were observed dynamically at day 1,3,5 after admission.Quantitative data with normal distribution were analyzed using t-test and abnormal distribution data were analyzed using Mann-Whitney U test.Categorical data were analyzed using χ2 test.Results The serum levels of cardiac index (CI), global ejection fraction (GEF) and left ventricular contractility index (dPmax) in myocardial depression group were all significantly lower than those in non-depression group at day 1 after admission (all P<0.01).The serum levels of sCD14-ST, TNF-α and BNP in myocardial depression group were all significantly higher than those in non-depression group (all P<0.01).Serum sCD14-ST levels in 84 septic patients were positively correlated with both BNP and TNF-α (r=0.204, P<0.05 and r=0.516, P<0.01, respectively).The area under the receiver operating characteristics curve (AUC) of sCD14-ST was 0.782 for myocardial depression in patients with sepsis, with a sensitivity of 89.2% and a specificity of 78.0% at the cut-off point of 988 mg/mL.The predictive value of sCD14-ST was inferior to BNP and TNF-α (both P<0.05).The combination of sCD14-ST, TNF-α and BNP could provide better prediction value in septic myocardial depression.Logistic regression analysis showed that serum sCD14-ST was not the in dependent predictor for septic myocardial depression (P>0.05).There were 24 cases died in myocardial depression group.The mortality of myocardial depression group was significantly higher than that of non-depression group (64.9% vs 42.6%, χ2=4.132, P =0.042).The serum levels of sCD14-ST at day 1 and day 3 in myocardial depression group were significantly higher than those in non-myocardial depression group (both P<0.01).sCD14-ST levels in both groups showed downtrend.The serum level of sCD14-ST in non-survival group was significantly higher than that in survival group (P<0.01).Conclusions Myocardial depression is common in patients with severe sepsis and septic shock.High serum level of sCD14-ST is correlated with myocardial depression to some extent, but not an independent predictor.The combination of sCD4-ST, BNP and TNF-α can improve the predictive value for myocardial depression.

In observing temperature changes in 100 cases of art ificial joint replacement,we discovered that the temperature curves p resented a “double peak” phenomenon.Accordingly,we analyzed the reasons for th is phenomenon and dealt with them,improving our nursing quality.

Objective To establish the system of statistic index of health examination information. Methods The items of health examination were screened, the valuable indexes for guiding the health condition were selected and standardized, and then the system of statistic index of health examination information was constructed. Results The 42 items for male clients and 74 items for female clients were selected as the statistic index of health examination information system. Standardized the statistic index with international classification of diseases system, including the criterion of name, diagnosis and data collection.The standard statistical tables were constituted. Conclusions Health examination information system can be statistically added up by standard index system.

· AIM: To evaluate the combined effect of rapamycin ophthalmic solution and cyclosporin A ophthalmic solution on allogeneic transplantation in a rat model.rats were used as donors. The animals were randomly assigned to 4 groups. Group A: control (ophthalmic solution solvent 100μ L); group B: 2g/L rapamycin ophthalmic solution 100μ L; group C: 10g/L cyclosporin A ophthalmic solution 100μ L; group D: 2g/L rapamycin ophthalmic solution 50μ L and 10g/L cyclosporin A ophthalmic solution 50μ L, 4 times every day. The treatment was started on 2d after operation, and the animals were administered until rejection. The grafts were inspected by slit-lamp microscope and the corneal survival time was recorded. The pathologic changes were measured by light microscope.significantly prolonged compared with the control group (P ＜ 0.01). However, the combined therapy (group D) was significantly superior compared with group B and C (P＜0.05, P＜ 0.01). The histopathological findings showed that the inflammation cells, neovascularity in each treated group were significantly fewer than that in control group at 14d after operation.a double drug regimen with rapamycin ophthalmic solution and cyclosporin A ophthalmic solution for the control of acute corneal allograft rejection. It indicats that the combined therapy produced synergistic effect.

Resveratrol, as a natural polyphenolic compound, has a wide range of beneficial effects, which includes anti-tumor, cardiovascular protection, anti-oxidant and estrogen-like effects, and so on. Its various physiological properties are closely related to the therapeutic principle for prevention and treatment of high altitude hypoxia injury. Resveratrol may play an important role in relieving or curing high altitude diseases, especially high altitude polycythemia(HAPC). However, the literature about study and application of resveratrol in plateau medicine field is rarely reported up to now. In this review, we summarized the physiological effects of resveratrol, discussed the possible main principle of resveratrol for HAPC therapy, and looked forward to resveratrol's perspective or potential application in high altitude medicine.
