Objective: To explore the relationship between plasma levels of soluble receptor of advanced glycation end products (sRAGE), brain natriuretic peptide (BNP) and cardiac function in patients with sepsis.
Methods: A total of 83 sepsis patients treated in our hospital from 2014-01 to 2015-06 were studied. Plasma levels of sRAGE, BNP were examined at 24 h after admission and they were evaluated by APACHEII scores. According to BNP levels, the patients were divided into 2 groups:Normal cardiac function group, the patients with BNP<500 pg/ml, n=32 and Cardiac dysfunction group, the patients with BNP≥500 pg/ml, n=51. The cardiac function as stroke volume (SV), LVEF, minute volume, E/A were examined by echocardiography. The above indexes were analyzed and compared between 2 groups, the relationship between plasma levels of sRAGE and the occurrence of sepsis was assessed by Logistic regression analysis.
Results: Compared with Normal cardiac function group, the patients in Cardiac dysfunction group presented decreased SV, LVEF, minute volume and E/A;increased APACHEII scores and sRAGE, all P<0.01. Plasma levels of sRAGE in sepsis patients were positively related to BNP (r=0.90, P<0.05) and APACHEII scores (r=0.85, P<0.05). Logistic regression analysis indicated that plasma levels of sRAGE (OR=1.019, 95%CI 1.004-1.035, P<0.05) was independently related to cardiac function in patients with sepsis.
Conclusion: Plasma levels of sRAGE were independently related to cardiac function in patients with sepsis.

To discuss IC50 application in cytotoxicity tests of medical devices, we firstly investigated the vibrating condition and endpoint of MTT method specified in ISO 10993-5: 2009. Furthermore, we demonstrated the application of IC50 in the result evaluation of MTT method. The experimental results show that usage of IC50 in quantitative evaluation of MTT method is feasible.

Objective The present study is to investigate the distribution of endogenous sulfur dioxide (SO2) in severe acute pancreatitis (SAP) rats.Methods Thirty-two SPF male Sprague-Dawley rats were randomized (random number) into sham operation group,SAP rat 3 h group (SAP 3 h),SAP rat 6 hgroup (SAP6h),SAP rat 12 hgroup (SAP 12 h),n=8 in each group.The SAPmodel rats were induced by retrograde cholangiopancreatic infusion of 5％ sodium taurocholate.Rats were sacrified 3 h,6 h or 12 h after treatment.,then we collected pancrease,liver,lung,kidney and serum.The SO2 concentration in each tissue or serum was detected by enzyme-linked immune sorbentassay.Results The concentration of SO2 in tissues of pancreas (1.72 ± 0.14) μmol/g,liver (1.62 ± 0.11) μmol/g,lung (1.65 ± 0.11) μ.mol/g,kidney (1.12 ± 0.06) μmol/g or serum (16.80 ± 1.27) μmol/g in SAP 3 h rats was not significant compared with the sham operation group (P ＞ 0.05 in each group).The SO2 content in the pancreas (1.89 ± 0.17) μmol/g,liver (1.92 ± 0.16) μmol/g,lung (1.91 ± 0.15) μmol/g,kidney (1.30 ± 0.10) μmol /g and serum (14.93 ± 1.00) μmol /g of SAP 6 h was significantly increased compared with sham operation group (P ＜ 0.05 each group).The content SO2 in the pancreas (2.31 ± 0.23) μmol /g,liver (2.22 ± 0.15) μmol /g,lung (2.17 ± 0.07)μmol /g,kidney (1.55 ± 0.15) μmol /gand serum (18.88 ± 1.56) μmol /g of SAP rats reached the peak 12Hafter treatment and was significantly higher compared with the sham operation group (P ＜ 0.05).Conclusions The increase of SO2 concentration in SAP might be,at least in our present opinion,involved into the pathogenesis of SAP rats.

OBJECTIVE： To provide reference for rational use of estradiol （E2） preparation in clinic. METHODS： The medical records of outpatients receiving assisted reproductive technology （ART） and E2 preparation [Estradiol valerate tablets （EV）， Complex packing estradiol tablets/estradiol and dydrogesterone tablets （EP）， Estradiol gel （EG）] were collected from the reproductive medicine center of a hospital during Jan. 2016-Mar. 2017. Taking drug instruction as standard， the rationality of medical records was evaluated from aspects of indication， route of administration， contraindication， usage and dosage， treatment course， etc. At the same time， these patients were followed up by telephone or outpatient service， and their pregnancy outcomes and ADR were summarized. RESULTS： A total of 12 646 prescriptions were collected， and 7 222， 3 912， 181 and 1 331 prescriptions used EV， EP， EG and EV+EP， respectively. The types of off-label use included over-indication， over-route and over-contraindication， and the rates of off-label use rates were 100％， 11.73％ and 43.60％， respectively. A total of 5 868 ART patients were involved； 439 patients received fresh embryo transplantation， and 5 429 patients received frozen-thawed embryo transplantation， involving 720 and 11 926 prescriptions， respectively. The rates of off-label use of above E2 preparations were 100％ （except for fresh embryo transplantation patients using EG）. As of Feb. 2018， the infant-holding rates of ART patients using EV， EP， EG and EV+EP were 85.29％， 85.37％， 86.36％ and 85.45％， respectively. No relevant ADR and neonatal birth defect was found. CONCLUSIONS： The phenomenon of off-label use of E2 preparations is widespread in the reproductive medicine center of the hospital. Although there is no indication of related safety risks， evidence-based evaluation should be carried out by enlarging the sample size in clinical practice， and careful use.

OBJECTIVETo study the correlation between fingerprints and body size indicators in adulthood.

METHODSSamples were composed of twins from two sub-registries of Chinese National Twin Registry (CNTR), including 405 twin pairs in Lishui and 427 twin pairs in Qingdao. All participants were asked to complete the field survey, consisting of questionnaire, physical examination and blood collection. From the 832 twin pairs, those with complete and clear demographic prints were selected as the target population. Information of Fingerprints pixel on the demographic characteristics of these 100 twin pairs and their related adulthood body type indicators were finally chosen to form this research. Descriptive statistics and mixed linear model were used for data analyses.

RESULTSIn the mixed linear models adjusted for age and sex, data showed that the body fat percentage of those who had arches was higher than those who did not have the arches (P = 0.002), and those who had radial loops would have higher body fat percentage when compared with ones who did not (P = 0.041). After adjusted for age, there appeared no statistically significant correlation between radial loops and systolic pressure, but the correlations of arches (P = 0.031)and radial loops (P = 0.022) to diastolic pressure still remained statistically significant.

CONCLUSIONStatistically significant correlations were found between fingerprint types and body size indicators, and the fingerprint types showed a useful tool to explore the effects of uterine environment on health status in one's adulthood.
