Rat models of diabetes were established by injecting streptozocin intraperitoneally.According to random number table,three groups were divided:normal group,diabetic group,and fisetin-treated group.After 24 weeks,all rats were sacrificed.Biochemical parameters of blood and urine samples were tested.The pathological changes were observed by paraffin sections staining with HE.The expression of extracellular matrix proteins was analyzed via PAS and Masson staining.Location of p300 protein expression was analyzed by immunohistochemistry.The protein expressions of p300 and MMP-2 were determined by Western blotting.The mRNA expressions of MMP-2 were analyzed via real-time PCR.The biochemical parameters and kidney pathological images in fisetin-treated group were better than those in diabetic group.The expression of extraeellular matrix proteins was lower than that in diabetic group.Immunohistochemistry analysis showed that among three groups the expression of p300 was mainly in glomeruli,and was also expressed in cell nucleus and cytoplasm and the coloration of fisetin-treated group was weakened as compared with diabetic group.Western blotting analysis showed that the expression of p300 protein in fisetin-treated group was lower than that in diabetic group(P＜O.05).The expressions of MMP-2 mRNA and MMP-2 protein were higher than those in diabetic group (P ＜ 0.05).It is suggested that fisetin may attenuate diabetes associated abnormalities in the kidney of rats,owing probably to inhibiting the expressions of p300 and enhancing the expressions of MMP-2.

Objective To investigate the protective effect of Ambroxol against experimental lung ischemia reperfusion (I/R) injury in a situ hilar clamp model.Method Left lung of rat was rendered and ischemic for 90 minutes,and reperfused for up to 2 hours,as the model.Twenty-four SD rats were randomly divided into 3 groups with 8 rats each group:control group,I/R group,I/R and Ambroxol treatment group (AMB group).Rats of AMB group received Ambroxol (25 mg/kg) Intraabdominally 30 minutes before ischemia and intravenously 5 minutes before reperfusion.After 2 hours of reperfusion,blood-gas analysis,the serum level of IL-1?,IL-8 and TNF-?from carotid artery were delected.The wet/dry ratio of lung,the activity of erythrocuprein (SOD),the content of malonaldehyde (MDA) and the activity of myeloperoxidase (MPO) were determined and pathematology changes were observed in the left lung tissue.Differences within the groups were analysed using two-sample t-test. Results After 2 hours of repeffusion,there were no significant changes of artery partial pressure of oxygen (PO_2) and partial pressure of carbon dioxide (PCO_2) among three groups.The wet/dry ratio of lung,the activity of MPO (U/g) and the content of MDA (nmol/mgprot) of I/R group were (5.3?0.5),(1.30?0.26) and (0.66?0.16),significantly higher than those of the control group (P

Fatty acids of Ralstonia solanacearum cultured under different temperatures, times, pH values and cultural media were detected by using gas chromatography (GC) method. Rs-J.1.4-010704-01v, a viru- lent strain of R. solanacearum isolated from ginger was chosen for the experiment. The results showed that the kind of fatty acid of Rs-J.1.4-010704-01v fluctuated from 14 to 33. The contents of its three plentiful fatty acids, C16:1?7c/C15:0 ISO 2OH, C16:0 and C18:1?7c (with retain times of 10.644, 10.950 and 14.177 min, respectively), also varied in a range of 55.66% to 75.69%. The diversification of the bacterium’s fatty acids at various cultural conditions was clustered into four groups by cluster analysis, according to the kinds and percentage contents of the fatty acids detected. The pathogenicities of Rs-J.1.4-010704-01v under 20?C and 25?C were deduced to be mid-virulent, with C16:0 less than C16:1?7c/C15:0 ISO 2OH. The bac- terium showed as a virulent strain under the other cultural conditions including 30?C~40?C, 24 h~96 h, pH 5~9 and four cultural media (LB、NA、TTC and TSB), with C16:0 more than C16:1?7c/C15:0 ISO 2OH.However, the difference between C16:0 and C16:1?7c/C15:0 ISO 2OH raised significantly from 2.35 to 13.23 under 40?C and 48 h~96 h. Meanwhile, the kind of fatty acid increased more than 30 as the cultural time increased. It was concluded that temperature and cultural time had more significant effects on the fatty acid composition of R. solanacearum than pH value and cultural medium.

Hyperlipidemia is a major factor causing coronary heart disease and atherosclerosis. The high-density lipoprotein cholesterol (HDL-C) is a major indicator for measuring lipid levels. However, there is no an effective medicine that can obviously increase HDL-C at present. According to previous laboratory studies, atractylodes macrocephalae extracts could significantly increase HDL-C level. In this study, the metabolic hyperlipidemia rat model was established by feeding high-sugar and fat diets and alcohol-drinking to explore the effect and mechanism of atractylodes macrocephalae extracts on hyperlipidemia rats. According to the findingins, different doses of atractylodes macrocephalae extracts could reduce the levels of TC, TG, LDL-C, ACAT and increase the contents of LCAT, HDL-C. Particularly, the atractylodes macrocephalae extracts (100 mg · kg(-1) group showed increase in HDL-C by about 50% and significant declines in HMG-CoA reductase, TC, TG. In conclusion, Atractylodes Macrocephelae Rhizoma extracts could effectively regulate the dyslipidemia of hyperlipidemia rats, especially on HDL-C. Its mechanism may be related to reduction in cholesterol synthesis by inhibiting HMG-CoA reductase in livers and increase in lipid metabolism and transport by regulating LCAT and ACAT levels.

Objective To evaluate the effect of ultrasound-guided arterial catheterization in internships of anesthesiology.Methods Sixty students were randomly divided into ultrasound-guided teaching group(n=30,3 male) and traditional teaching group (n=30,4 male).In the two groups,the ultrasound-guided arterial catheterization technology and artery catheterization technique were adopted respectively for teaching.The success rate of arterial catheterization was compared between the two groups after 2 months internships and when finishing internships of anesthesiology.The questionnaire was investigated in ultrasoundguided teaching group after finished internships of anesthesiology.Results The success rate of arterial catheterization in ultrasound-guided teaching group was extremely higher than in traditional teaching group after 2 months internships of anesthesiology (52 ± 8)％ vs.(38 ± 10)％,(x2=7.746,P=0.005).After finishing internships of anesthesiology,the success rate of arterial catheteri-zation was (67±7)％ in ultrasound-guided teaching group and (59 ± 9)％ in traditional teaching group (x2=5.531,P=0.036).And all students thought ultrasound-guided arterial catheters teaching was helpful to them and could improve their learning interest.Conclusion Ultrasound-guided arterial catheterization is beneficial to the internship teaching of undergraduate of anesthesiology,which can help them to master the arterial catheterization technique better,and improve the success rate of arterial catheterization and their learning interest.

Objective Although heart transplantation (HTx) has become a standard therapy for end-stage heart diseases,experience with pediatric HTx is limited in China.In this article,we will try to provide the experience with indications,complications,perioperative management,immunosuppressive therapy,and survival for pediatric HTx based on our clinical work.Method This is a retrospective chart review of the pediatric patients undergoing HTx at Department of Cardiovascular Surgery of Union Hospital from September 2008 to December 2015.We summarized the indications,surgical variables,postoperative complications,and survival for these patients.Result Twenty-three pediatric patients presented for HTx at Union Hospital of Tongji Medical College,of whom 12 were male.The age at the time of transplantation ranged from 3 months to 18years (median 14 years).Patient weight ranged from 5.2 kg to 57.0 kg (median 36.0 kg).Pretransplant diagnosis included cardiomyopathy (16 cases),complex congenital heart disease (5cases) and tumors (2 cases).All recipients received ABO compatible donor hearts.Postoperative complications occurred in 14 patients,including cardiac dysfunction,arrhythmia,pulmonary infection,renal dysfunction,and rejection.Two of them experienced cardiac failure and required extracorporeal membrane oxygenation.The immunosuppression regimen was comprised of prednisone,a calcineurin inhibitor,and mycophenolate.All patients recovered with New York Heart Association (NYHA) Class Ⅰ Ⅱ cardiac function and were discharged.Only one patient suffered sudden death 19 months after transplantation.Conclusion Orthotopic HTx is a promising therapeutic option with satisfactory survival for the pediatric population in China with end-stage heart disease.

According to the characteristics of sludge samples from full-scale wastewater treatment bioreac-tors, the essential total DNA extraction method for most environmental samples, lysozyme-SDS-phenol/ chloroform method, was modified to improve sample pretreatment, intensify cell lysis and enhance the effi-ciency of impurity removal. Obtain a general total DNA extraction method for industrial sludge samples. Such a method was applied for total DNA extraction of sludge samples from several running full-scale an- aerobic or aerobic bioreactors in Shijiazhuang, China. The results indicated that the modified method was suitable for all the sludge samples in this study, showing the satisfying generality. The extracted total DNA of all sludge samples were pure, with about 1.8 of A260/ A280 ratio. The method was also efficient; with average total DNA yield of over 0.7 mg/g and maximum yield of 0.85 mg/g. Moreover, all the extracted to- tal DNA samples could serve as templates directly to amplify 16S rDNA by PCR. The PCR products could be separated well by denaturing gradient gel electrophoresis (DGGE) and the DGGE band patterns were clear enough to be used for further analysis. All these facts indicated that the total DNA extraction method provided in this study could meet the requirements of sludge samples research, from full-scale wastewater treatment bioreactors, using molecular biology technologies.
