Objective To investigate the clinical significance of plasma presepsin levels in patients with sepsis. Methods 92 patients who were admitted to the ICU of the affiliated hospital of Jiangsu University from October 2011 to March 2013 and 30 age-matched healthy controls were enrolled in this study. The patients were divided into three groups: sepsis, SIRS, and control. Plasma presepsin and serum procalcitonin (PCT) were measured, APACHEⅡscore were calculated at enrollment, and ROC curve was used to analyze the performance index for the diagnosis of sepsis. Results Serum levels of presepsin, PCT and APACHEⅡscore were significantly higher in the death group than in the SIRS group and the control group (P<0.01). Serum levels of presepsin and PCT were higher in the sepsis group than in the SIRS group and the control group (P<0.05). There was no significant statistical difference between the SIRS group and the sepsis group in the APACHEⅡ score (detailed in table 1). Level of plasma presepsin was significantly correlated with serum PCT (r = 0.82); plasma presepsin level was related with the APACHEⅡ score (r = 0.69). The area under the curve (AUC) of presepsin was 0.908 (95%CI 0.848~0.967), greater than the AUC of PCT 0.862 (95%CI 0.787~0.937). The cutoff value of presepsin for discrimination of bacterial and nonbacterial infectious diseases was determined to be 629 pg/mL, of which the clinical sensitivity and specificity were 68.6% and 90%, respectively; when the cutoff value of PCT was 1.98 ng/mL, the clinical sensitivity and specificity were 92%and 65%. Conclusions Level of presepsin increases in patients with sepsis, and an elevated presepsin may suggest the severity of sepsis.

Objective To investigate the etiology of early postoperative hyperbilirubinemia after liver transplantation.Methods The clinical data of 87 cases of liver transplantation and the etiology of early postoperative hyperbilirubinemia after liver transplantation were analyzed.Results The incidence of early postoperative hyperbilirubinemia after liver transplantation was(52.87 %).In 21 postoperative complications,17((80.95 %)) were associated with hyperbilirubinemia.The causes of hyperbilirubinemia were as follows in turn: ischemic-reperfusion injury(n=(25,28.73 %)),complications of(common) bile duct(n=23,(26.44 %));acute rejection(n=19,(21.84 %));others(n=13,(14.94 %)).(Conclusions) The early postoperative hyperbilirubinemia is the most common clinical manifestation in(patients) undergoing liver transplantation and can be taken as a reliable clinical mark for the postoperative complications and liver functions.The etiology of early postoperative hyperbilirubinemia after liver transplantation is very complicated.Early diagnosis and treatment is helpful to improve the survival of patients undergoing liver transplantation.

To modify the surface property of poly lactide-co-glycolide (PLGA) by biomimetic mineralization to construct a new kind of artificial bone. PLGA films and 3-diamensional (3-D) porous scaffolds hydrolyzed in alkaline solution were minerilized in SBF for 14 days. The morphology and composition of the mineral grown on PLGA were analyzed with SEM, FTIR and XRD. The porosity of the scaffolds was detected by using the liquid displacement method. The compressive strength of the scaffolds was detected by using a Shimadzu universal mechanic tester. An obvious mineral coating was detected on the surface of films and scaffolds. The main component of the mineral was carbonated hydroxyapatite (HA) similar to the major mineral component of bone tissues. The porosity of the un-mineralized and mineralized porous scaffolds was (84.86 +/- 8.52) % and (79.70 +/- 7.70) % respectively. The compressive strength was 0.784 +/- 0.156 N/mm2 in un-mineralized 3-D porous PLGA and 0.858 +/- 0.145 N/mm2 in mineralized 3-D porous PLGA. There were no significant differences between the mineralized and un-mineralized scaffolds (P > 0.05) in porosity and biomechanics. Biomimetic mineralization is a suitable method to construct artificial bone.

OBJECTIVETo investigate whether intracytoplasmic sperm injection (ICSI) can improve the clinical outcomes of the male patients with 100% teratozoospermia.

METHODSWe retrospectively analyzed the clinical data of 152 couples undergoing in vitro fertilization-embryo transfer (IVF-ET), including 75 cycles of IVF and 77 cycles of ICSI. We compared the rates of normal fertilization, high-quality embryos, transferrable embryos, implantation, clinical pregnancy, and abortion between the two groups.

RESULTSIn the 100% teratozoospermia patients the number of transferrable embryos was significantly lower in the IVF than in the ICSI group (78.91% vs 84.92%, P < 0.05), while the rates of normal fertilization and implantation were higher in the former than in the latter (60.26% vs 57.87% and 48.00% vs 39.55%, both P > 0.05). There were no statistically significant differences between the two groups in the female age, Gn days, Gn dose, BMI, infertility duration, endometrial thickness, and basal serum FSH and E2.

CONCLUSIONICSI cannot improve the clinical outcomes of the male patients with 100% teratozoospermia.

OBJECTIVETo observe the effect of a integrative medical regimen (IMR), i.e. combined use of Jiangya Capsule (JYC) and Nimodipine (ND), on blood pressure, TCM clinical symptoms, and blood levels of vascular endothelial function and hypersensitive C-reactive protein (hs-CRP) in elderly patients with isolated systolic hypertension (EISH).

METHODSAdopting randomized, double-blinded and controlled principle, a trial was conducted on 135 patients with EISH by randomized them into three groups, they were administered IMR (Group A), JYC plus ND simulator (Group B) and ND plus JYC simulator (Group C) respectively, for 4 weeks. Changes of blood pressure and TCM symptoms, as well as the levels of serum nitric oxide (NO), plasma endothelin-1 (ET-1), 6-keto-prostaglandin 1alpha (6-keto-PGF(1alpha)), thromboxane B2 (TXB2) and hs-CRP were observed before and after treatment.

RESULTSAfter treatment the systolic blood pressure reduced and clinical symptoms improved, with serum NO and 6-keto-PGF(1alpha) lelels elevated, plasma ET-1, TXB2 and serum hs-CRP decreased in all the three groups (P<0.05 or P<0.01). But the inter-group comparisons showed that the effect in Group A was superior to the other two groups in decreasing systolic pressure, and superior to Group C in improving clinical symptoms, elevating serum NO and decreasing plasma TXB2 (P <0.05).

CONCLUSIONThe integrative medical regimen of combined use JYC and ND has markedly effect in lowering blood pressure, it could obviously improve the symptoms and vascular endothelial function, and inhibit the level of inflammatory factor in patients with EISH.

Objective To understand the pattern of and influencing factors on leisure time physical exercises among adults in Zhejiang. Method Totally 17 437 residents aged 18 years and over selected by stratified cluster random sampling in Zhejiang in 2010 were investigated. Result Overall 21.82%(95%CI:17.12%-27.38%) of adults took part in leisure time physical exercises in 2010. The proportion was higher in urban (29.04%,95%CI:23.46%-35.33%) than in rural (18.81%,95%CI:12.89%-26.61%) (χ2=222.06, P<0.05) areas, and also higher in females (22.91%,95%CI:17.66%-29.15%) than in males (20.56%,95%CI:16.39%-25.48%) (χ2=13.94, P<0.05). Adults aged 18-24 and 55-74 years were more likely to take apart in physical exercises (χ2=266.73, P<0.05), and the lowest proportion was found among farmers (5.33%,95%CI:3.99%-7.11%) (χ2=2 078.40, P<0.05). These proportions both increased along with education level and family income increase (χ2=444.87, P<0.05;χ2=332.20, P<0.05). Overall 83.04%and 90.08%of physical exercisers took part in exercises at least 3 times per week and 30 minutes per time, only 30.67% of those reached moderate or vigorous intensity, and overall 5.38% (95%CI: 3.85%-7.48%) of adults took part in regular leisure time physical exercises in 2010. Multiple logistic regression showed that age, education level, occupation and chronic disease history have influence on regular physical exercises. Conclusion The leisure time physical exercises level was generally low among adults in Zhejiang. Young and middle-aged adults with less education and low income especially farmers should be put on emphasis.

Objective Toll-like receptor ( TLR) gene family is the most important pathogen recognition receptor and animal experiment have found TLR4 mice is inclined to infect aspergillosis ( IA) .The study was to investigate the variation of TLR4 gene in Chinese Han nationality and its relation with the susceptibility of IA. Methods 25 patients diagnosed with proven IA from June 2011 to December 2012 in our hospital were enrolled, among which 17 were males.Their average age was 52.4 ±12.3, and 12 pa-tients had underlying diseases, the others had no underlying diseases.The control group consisted of 103 normal persons, among which 70 were males.Their average age was 56.0 ±17.2.All of the subjects were Chinese Han population.DNA was extracted from periph-eral blood.Polymerase chain reaction ( PCR) was applied to amplify the coding sequence of TLR4 gene followed by sequencing.The sequencing result was compared with TLR4 coding sequence in NCBI GenBank along with the analysis on amino acid change caused by genetic mutation and its effect on protein function.Comparison analysis was made on genetic mutation rate between IA group and con-trol group. Results Two missense mutations,TLR4 219 C>G and 1420 C>T, were identified in TLR4.The prediction result of protein structure showed 219 C>G resulted in the change of functional area for TLR4 to recognize pathogen and 1420 C>T caused no change in domains.The variation rate of TLR4 in IA group was 8%( 2/25 ) and both the patients had no underlying diseases. No mutation has been founded in control group and the difference between two groups was of statistical significance (P=0.037). Conclusion Two missense mutations (219 C>G and 1420 C>T) have been detec-ted in encoding area of TLR4 gene of IA patients.Variation in the cod-ing region of TLR4 gene may increase the susceptibility to IA.

Objective To assess the efficacy and safety of fluvastatin sodium extended-release tablets (fluvastatin XL) 80 mg once daily compared to fluvastatin sodium immediate-release capsules (fluvastatin IR) 40 mg twice daily in Chinese hyperlipidemic patients with moderate or high cardiovascular risk.Methods In this multi-center,randomized,double-blind,double-dummy,active-controlled,parallel-group study,after 6-week open-label treatment with fluvastatin IR 40 mg once daily,patients who did not reach their lipid goals were randomized to 12-week double-blind treatment with fluvastatin XL 80 mg once daily or fluvastatin IR 40 mg twice daily.Results (1) There were 218 patients enrolled in each group.At the study endpoint,no statistical difference was found in the mean percent change from baseline for LDL-C with-8.69％ [from (3.504 ±0.060) mmol/L to (3.153 ±0.065) mmol/L] in the fluvastatin XL group and-7.89％ [from (3.491 ±0.050) mmol/L to (3.181 ±0.060) mmol/L] in the fluvastatin IR group (P ＞ 0.05).The 95％ CI for difference between the two groups in adjusted mean percent change from baseline was (-4.70％-3.09％),which was within the pre-specified non-inferiority margin.In the fluvastatin XL group,the proportion of patients with moderate cardiovascular(CV) risk and high CV risk achieving their LDL-C treatment goals at endpoint was 50.0％ and 31.5％ respectively,while the proportion was 42.5％ and 24.5％ respectively in the fluvastatin IR group.No significant difference was found between the two groups in the proportion of patients who reached their lipid goals and the changes from baseline with other lipid parameters.(2)Similar safety profiles were observed in the two treatment groups,with 21.1％ adverse event (AE) (8.3％ study-drug related AE) in the fluvastatin XL group and 17.0％ AE (6.3％ study-drug related AE) in the fluvastatin IR group.Conclusion The efficacy of fluvastatin XL 80 mg once daily is comparable to fluvastatin IR 40 mg twice daily in Chinese hyperlipidemic patients with moderate or high cardiovascular risk and both treatments are safe and well-tolerated.

AIM:To observe the effect of Wnt/β-catenin signaling pathway on diabetic ulcer.METHODS:Diabetic animal model was established in the female Wistar rats by intraperitoneal injection of low-dose streptozotocin fol-lowing high-fat diet feeding.A circular wound was made on the dorsum of the rats in both control group and diabetic group. The condition of wound healing was recorded and the structures of the wound tissues were observed by HE staining in the 2 groups at 3, 7 and 14 d after wounding.The expression ofβ-catenin, GSK-3βand Rspo-3 at mRNA and protein levels in the wound tissues was detected by RT-PCR and ELISA.RESULTS:In diabetic group, the wound healing rate was lower (P<0.05), and the inflammatory cells, fibroblast cells and new capillaries in the wound tissues were fewer than those in control group.The expression of β-catenin and Rspo-3 at mRNA and protein levels in the wound tissues in control group was significantly higher than those in diabetic group, and the expression of GSK-3βwas exactly the opposite (P<0.05). CONCLUSION:The down-regulation of Wnt/β-catenin probably resultes from the decreased level of Rspo-3, which may be one of the reasons for delaying the diabetic ulcer healing.
