Objective To explore the role of apelin in the pathogenesis of diabetic nephropathy.Methods A total of one hundred and fourteen patients with type 2 diabetes mellitus in Qingdao Municipal Hospital from July 2015 to June 2016 were divided into normal albuminuria group (56 cases in the NA group) and micro-albuminuria group (58 cases in the MA group),depending on whether the level of urinary micro-albumin in 24 h was higher than 30 mg,with 60 healthy subjects included as the controls group (NC group).Levels of serum apelin and other biochemical indexes were tested.Results (1) WC,BMI,TC,TG,LDL-C,FBG,FINS,HOMA-IR and apelin in the patients of the NA group and MA group were respectively (87.99±10.27) cm,(24.75±3.35) kg/m2,(5.27±1.28) mmol/L,(1.84±1.25) mmol/L,(3.36±0.91) mmol/L,(7.58±0.87) mmol/L,(13.29±3.57) U/L,4.50±1.41,(364.22±85.03) ng/L ,(90.10±8.97) cm,(25.47±2.82) kg/m2,(5.19±1.11) mmol/L,(2.23±1.43) mmol/L,(3.68±0.83) mmol/L,(7.89±1.11) mmol/L,(15.50±5.00) U/L,5.55±2.27,(397.42±91.29) ng/L,which were higher than those of the NC group ((83.20±5.36) cm,(22.59±2.67) kg/m2,(4.68±1.10) mmol/L,(1.37±0.58) mmol/L,(2.56±0.94) mmol/L,(5.11±0.82) mmol/L,(7.17±2.80) U/L,1.65±0.77,(309.34±68.28) ng/L,P<0.05).FINS,HOMA-IR and apelin in the MA group were significantly higher than those in the NA group (P<0.05).(2) After age,sex and BMI were taken into control,partial correlate analysis showed that serum apelin was positively correlated with LDL-C,FPG,FINS and HOMA-IR (r=0.183,0.314,0.374,0.378,P<0.05).(3) Multifactor regression analysis showed that HOMA-IR and BMI were independent related factors to serum apelin (r2=0.288,0.389,P<0.05).Conclusion Apelin levels in the MA group were significantly higher than those in the NA group,and the serum apelin was positively correlated with HOMA-IR.Thus,apelin may contribute to the pathogenesis and progress of diabetic nephropathy.

Objective To assess the effects of fluvastatin retard tablets on the elder patients of acute coronary syndrome(ACS) complicated with diabetes mellitus(DM) undergoing percutaneous coronary intervention (PCI) and the safety of drugs.Methods From December 2009 to December 2011,78 elderly patients (age≥65 years) of ACS complicated with DM who underwent PCI were enrolled in this study.They were all treated by drug elution stents.They were divided into group A(fluvastatin retard tablets 80 mg/d) and group B (fluvastatin retard tablets 160 mg/d) with 39 cases each by random digits table method.The plasma levels of high sensitivity C reactive protein (hs-CRP),matrix metalloproteinase proteinase 9 (MMP-9),monocyte chemoattractant protein 1 (MCP-1) and lipid levels were measured before and after treatment of 24 h,7 d and 180 d.All the patients were followed up for 180 d,and the adverse reaction of drug and the incidence of cardiovascular event were detected.Results Blood lipid levels had no significant changes in the two groups before and after treatment (P ＞ 0.05).The plasma levels of hs-CRP,MCP-1,MMP-9 were higher after treatment of 24 h than those before treatment in two groups [group A:(12.14 ± 2.71)mg/L vs.(8.76 ±2.25) mg/L,(491.75 ± 19.29) ng/L vs.(440.56 ± 13.15) ng/L,(449.6 ±11.8) μmol/L vs.(353.8 ± 16.0) μ mol/L;group B:(11.39 ± 2.38) mg/L vs.(9.30 ± 1.99) mg/L,(488.56 ± 17.61) ng/L vs.(436.06 ± 15.36) ng/L,(444.9 ± 19.1) μ mol/L vs.(349.8 ± 13.6) μmol/L],and there were significant differences (P ＜ 0.05).The plasma levels of hs-CRP,MCP-1,MMP-9 decreased significantly after treatment of 7,180 d compared with that after treatment of 24 h in two groups (P ＜ 0.05).Compared with those in group A,the plasma levels of hs-CRP,MCP-1,MMP-9 decreased even lower in group B[after 7 d:(4.51 ±1.16) mg/L vs.(5.43 ± 1.44) mg/L,(306.06 ± 18.49) ng/L vs.(384.64 ± 13.23) ng/L,(206.2 ± 16.8)μ mol/L vs.(263.4 ± 15.4)μ mol/L;after 180 d:(4.23 ± 1.08) mg/L vs.(4.68 ± 1.46) mg/L,(280.16 ± 14.54) ng/L vs.(354.64 ± 11.32) ng/L,(187.2 ± 14.2)μ mol/L vs.(225.4 ± 12.7) μ mol/L],and there were significant differences (P ＜ 0.05).After followed up for 180 d,there was no serious adverse reaction in two groups,and the total incidence of cardiovascular event in group B was lower than that in group A [7.7％(3/39) vs.25.6％ (10/39)],and there was significant difference (P ＜ 0.05).Conclusion Intensive lipid lowering therapy can reduce the level of inflammatory factors and cardiovascular event of the elder patients of ACS complicated with DM undergoing PCI and has good security.

Objective:To investigate the relationship of polymorphism of leptin receptor gene Gln223Arg with asthma and metabolic syndrome.Methods: Collected 120 asthma patients,92 metabolic syndrome patients,54 asthma combined metabolic syndrome patients and 81 normal controls.According to the severity,the asthma patients were divided into mild-medium group and severe group.The serum leptin level was measured by ELISA,the genotypes of leptin receptor were analyzed by the method of polymerase chain reaction-restriction fragment length polymorphism(PCR-RFLP),and statistcs of each subject′s MBI,blood pressure,lung function and fasting blood glucose were collected.Results: ①There were significant differences in genotype and allele frequency in leptin receptor gene Gln223Arg between the metabolic syndrome group,asthma combined metabolic syndrome group and normal control group(P<0.05).②The allele frequency and genotype in leptin receptor gene Gln223Arg were significant different between the severe asthma group and normal control group(P<0.05).③The serum leptin level,BMI and systolic blood pressure of AA+AG genotype group were significiant higher than GG genotype group(P<0.05),while the value of FEV1% and FEV1/FVC of lung function were lower than GG genotype group(P<0.05).Conclusion: Leptin receptor gene Gln223Arg polymorphism is correlated with asthma and metabolic syndrome,and by causing leptin resistance,the A allele might be the genetic factor that contribute to individual susceptibility for asthma and metabolic syndrome.

Objective:To study the preventive and therapeutic effects of silk fibroin peptides (SFP) on acute alcoholism in mice. Methods:In first experiment, the mice were randomly divided into four groups, and every group was treated by 56o alcohol (ethanol dosage 7.56 ml/kg bw) via i.g. Eighty mice were fed normal saline (NS) and different dosages of SFP (0.1, 0.5, 2.5 g/kg bw) 30 min later respectively, then the rate of ebriety and time of sobriety were determined. Another 72 mice were also divided into four groups and given NS and SFP similarly. The concentration of ethanol in serum was measured 1 h, 2 h and 4 h later respectively. In second experiment, the mice were also divided into four similar groups, but 56o alcohol was given at 6.16 ml/kg?bw via i.g. NS and SFP were given similarly, 0.5 h before alcohol. Two experiments were performed to observe the effect of SFP on prevention of temulence. Results:The time of sobriety and concentration of ethanol of SFP groups fed 0.5 and 2.5g/kg bw were lower significantly than those of NS group (P

Objective To observe the effects of secoisolariciresinol (SECO) and its metabolites, enterolactone (ENL) and enterodiol (END), on proliferation of MCF-7 cell line and to the probable mechanism. Method Effect of SECO, END, ENL and genistein (GEN) on MCF-7 proliferation was investigated by MTT assay. Cell cycle arrest was measured by flow cytometry (FCM). Cell morphology was observed by optical microscope. The anticarcinogenic mechanism of SECO was analyzed. Results SECO had promotive effect on the cell growth at lower concentration (≤40 ?mol/L) but inhibition effect at higher concentration (100 ?mol/L). ENL and END, however, showed significant inhibition effect at all tested concentrations (10~100?mol/L). The cell cycle progression was arrested at G2/M phase and apoptosis was observed by optical microscope. Conclusion Effect of SECO on the MCF-7 cell proliferation depends on its concentration. Inhibition effect of SECO may relate to its metabolites ENL or END.

Objective To investigate the expression of complement regulatory proteins on placentas of pregnant C57BL/6 mice infected with Toxoplasma gondii in order to explore the molecular immunological mechanism for abnormal pregnancy induced by T. gondii infection. Methods Twenty-four pregnant C57BL/6 mice were randomly divided into two groups equally. The infection group was intraperitoneally injected with 200 of living T, gondii RH strain tachyzoites on the 8th day of gestation, and the normal group of mice was injected with physiological saline. All mice were killed on day 14 after gestation and placentas were collected. The expression levels of Crry, GPI-DAF and CD59a mRNA were analyzed by real-time quantitative PCR, and the positive rates of Crry and GPI-DAF were measured with flow cytometry. Results The died fetus rates of infected group and control were 80. 95% and 4. 41% , respectively. The infected group was significantly higher than of that the control group (P＜0.01). The expression levels of Crry, GPT-DAF and CD59a mRNA in the infected and control group were 0.786 ±0. 199, 0.594 ±0.096, 0.880 ±0. 179 and 0.550 ±0.077, 0.221 ±0.074, 0.591 ± 0.075 , respectively, and the difference of three kind of complement regulation proteins between two groups was all significant (P＜0.01). The positive percentages of Crry and GPI-DAF cells of infected and control group were (10. 03 ± 2. 11) % , (2.95 ±1.04)% and (3. 15 ± 1. 32) % , (0. 66 ±0. 26) % , respectively, and the difference of the two kind complement regulation proteins between two groups was also significant ( P ＜ 0. 01). Conclusion The expression level of mouse placental complement regulatory proteins was increased after infection with T. gondii, and then immunological microenvironment at the fetomaternal interface was destroyed. It may be one of important immunological mechanism for abnormal pregnancy induced by T. gondii infection.

Burn infection occurs when pathogenic bacteria colonized on the burn wound surface, and they then invaded the viable tissue causing sepsis or sepsis with blood stream invasion. This infection pattern is particular to burn injury. Both in a model of pseudomonas burn wound sepsis and a clinical study of early eschar excision for bacteria quantification indicate that the bacteria not only are located on the burn wound surface but also invaded the deeper tissues. Finally, the bacteria penetrate into the neighboring viable tissue and even blood vessels. Therefore, we can say that burn infection is from local wound infection to invasive infection, and finally sepsis is developed ,and it is termed as burn wound sepsis. The cutoff count of subeschar tissue bacteria is 10(5)/g. However, the burn wound sepsis may not occur when the number of subeschar tissue bacteria reaches 10(5)/g. The criteria for the diagnosis of burn wound sepsis are mainly listed as below: (1) The number of bacteria in the subeschar reaches > or =10(5)/g. (2) Bacteria can be detected in the biopsy specimen. (3) Sepsis associated symptoms and signs. However, the sepsis associated symptoms and signs must be obvious in patients to make the clinical diagnosis of burn wound sepsis. If the sepsis associated symptoms and signs do not appear, we should not make the diagnosis of burn wound sepsis eyen with the number of bacteria in the subeschar tissue reaching 10(5)/g or bacteria can be found in the biopsy specimen. Sepsis has been defined as the body % response to bacteria and their products. The occurrence of sepsis depends primarily on immune function and stress response intensity, and it is closely related to wound infection degree such as bacteria density and invasion depth in the burn wound, or plasma endotoxin level to certain extent.

The main factors influencing the bacterial ecology on burn wound are the selection of antibacterial agents and systemic antibiotic. Some antibacterial agents more active against P. aeruginosa were developed in 1960s, and the detection rate of P. aeruginosa on burn wound has been declined, and the detection rate of Enterobacteriaceae species and Acinetobacter SPP. has been raised since then. In 1990s, the third generation Cephalosporin was widely used in burn unit and the detection rate of staphylococcus aureus showed an increased trend. Especially, the positive rate of MRSA was increased significantly. Under the selection pressure of antibacterial agent, the resistant strains are rapidly increased and the antibiotics against opportunistic pathogen on burn wound should be selected continuously. Finally, the bacterial ecology pattern on burn wound is changing incessantly. The result is that the prevalence of infection of multi-drug resistance strains and opportunistic pathogen appears on burn wound. In order to optimize the antibiotic therapy, the bacterial ecology pattern on burn wound has to be investigated, and the dominant pathogen including invasive and currently prevailing strains in the burn unit also should always be surveyed. In addition, we also should know the mechanisms of bacterial resistance. The regular surveillance of antibiotic resistance in the clinical isolates is the most important and valuable for understanding the trend of bacterial resistance. The antibiotic therapy should be decided according to the result of susceptibility tests.
