Objective To explore the possible molecular mechanism of Ginsenoside Rg1 preventing against 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine(MPTP)-induced substantia nigra neurons apoptosis in Parkinson disease(PD) mouse model. Methods C57BL mice were administrated(sc) with MPTP to produce PD mouse model.Different doses of Rg1(5.0,10.0,20.0*!mg/kg) were given(ip) prior 3*!d to MPTP in the pretreatment groups.Nissl staining,tyrosinehydroxythase(TH) immunostatining,cleaved caspase-3 immunostatining and TUNEL staining were used to observe the changes of nigra neurons,meanwhile,Western blot was used to detect the phosphorylated protein of JNK and c-Jun in substantia nigra. Results Pretreatment with Rg1 could prevent the loss of Nissl staining neurons and TH-positive neurons,inhibit JNK and c-Jun phosphorylation in SN,decrease the percent of cleaved caspase-3 and TUNEL-positive cell.Conclusion Rg1 can attenuate MPTP-induced apoptosis in substantia nigra neurons through blocking JNK signaling cascade.

Objective To analyse the sonographie characteristics of thyroid nodules after injection and investigate the contrast enhanced ultrasonography. Methods Analysed the sonographic characteristics in 32 cases and observed the dynamic enhancement pattern of nodules by the time-intensity curve(TIC). The evaluated parameters were arrival time (AT), time to peak(TTP), peak intensity(PI). Results Thyroid cancer (12 cases) showed early wash in an early wash out in comparison with the adjacent thyroid parenchyma, and the enhancement intensity [AT(7.49 ± 4.45), TIP( 17.41 ± 2.84), PI( 18.56 ± 5.24) s] were lower than nodular goitre (20 cases) [ AT ( 13.22 ± 3.30), TIP (20.92 ± 2.59), PI ( 19.15 ± 5.47 ) s ] (P < 0.05 ). Conclusion The contrast enhanced ultrasonography may provide a useful method for the diagnosis of thyroid cancer.

Objective To investigate the effect of enteral nutrition support on prognosis in patients with severe acute stroke.Methods Ninety-eight cases of severe acute stroke were divided into nutrition supported group(50 cases) and control group(48 cases) randomly.All patients were treated by conventional therapy.Nutrition supported group received high energy nutrition diet and control group received common liquid diet by nasal feeding.The levels of hemoglobin,serum albumin,neurologic impairment score (NIHSS)and the incidence rates of complications were assessed at the 1st,10 th and 21st day after admission.Results Hemoglobin was (122.5 ± 2.4),(106.4 ± 2.8) g/L and serum albumin was (36.5 ± 4.7),(34.2 ± 5.1) g/L at the 21st day after admission in nutrition supported group and control group,and there was significant difference between two groups (P < 0.05).The complication rate in control group was higher than that in nutrition supported group (P< 0.05).NIHSS score was(8.45 ± 3.02) scores in nutrition supported group and (10.24 ± 2.57)scores in control group at the 21st day after admission,and there was significant difference between two groups (P <0.05).Conclusion Early enteral nutrition support can significantly improve nutritional status and decrease the incidence rates of complications in patients with severe acute stroke,and it is helpful for clinical prognosis.

Objective To investigate the clinical application of anti-β2 glyeoprotein Ⅰ antibodies (IgG, IgM, IgA)in systemic lupus erythematosus(SLE). Methods The anti-β2-GP Ⅰ antibodies and anti-cardiolipin antibodies(ACL) level were measured by ELISA in 100 SLE patients, 39 other rheumatoid arthri-tis patients and 30 healthy control people. Their clinical application was analyzed in SLE diagnose and thera-py. Results The level of anti-β2-GP Ⅰ (IgG, IgM, IgA)were significantly higher in SLE than that in healthy (P < 0. 01 ). Sensitivity, specificity, positive predictive value and negative predictive value were 17.2%, 95.7%, 85.0% and 44. 6%, respectively. There was a significant and positive correlation be-tween anti-β2-GP Ⅰ antibodies and ACL antibodies ( IgG, IgM, IgA) (r = 0.418, 0. 624, 0.518, 0. 583, P <0.01). In multivariate analysis the factors(anti-β2-GP Ⅰ antibodies, ACL antibodies, dsDAN, u1-RNP, Sm, SSA, SSB, Jo-1, Scl-70, P-protein, PT, APTT) associated with SLE disease activity index(SLEDAI) were anti-β2-GP Ⅰ (IgG) and dsDNA. Conclusion anti-β2-GP Ⅰ antibody has high specificity and positive predict value, also is associated with SLE's thrombosis. It has some values in the clinical application.

Objective The degradable artificial material—poly(lactic-co-glycolic acid) (PLGA) was used as the scaffold of the tissue engineering blood vessel for cells implantation,and the better requirement for cell culture was studied.These results may be useful to the manufacture of small diameter tissue engineering blood vessel used in clinical in future.Methods The nonwoven mesh degradable PLGA was used as tissue engineering scaffold.The smooth muscular cell(SMC) and endothelial cell (EC) harvested from fetus umbilical blood vessel were collected as the seeding cells.The SMC and EC were cultivated for 4 weeks respectively in vitro.Then,the SMC was seeded on the surface of the PLGA 4 weeks later,the EC was seeded on the surface of the SMC layer and PLGA.After another 4 weeks,the artificial blood vessel segment with seeding cells was examined in the cellular quality and activity.Results By immunohistochemical method,all test expressions were positive in staining smooth musle actin,yon Willebrand 、CD31 and CD34.By radioimmunoassay,the levels of endothelin and 6-Keto-PGF1 a in PLGA cell culture solution were higher than in control soulture (P ＜ 0.05).These demonstrated that all cells seeded on PLGA still have cellular activity.All seeding cells showed the typical SMC or EC morphological appearances in light microscopic and scanning electric microscopic analyses.Conclusion The results show that the SMC and EC from umbilical vessel,after being cultivated in vitro,as the seeding cells seeded sequentially on the degradable blood vessel scaffold (PLGA),still possess the cellular activity.This may be useful in further studying the small diameter tissue engineering blood vessel.

Objective To explore the relationship between blood lipids level with creatinine clearance rate(Ccr)in patients with heart failure(HF). Methods A total of 955 patients who were diagnosed with heart failure(cardiac function NYHAⅡ~Ⅳclassification)upon discharge from the Department of Cardiology of the Second Hospital of Tianjin Medical University, between January 2010 to June 2013 were enrolled as HF group. Healthy adults (n=200) with normal cardiac function which approximately matched basic condition with HF group were selected as control group. The HF group was fur?ther divided intoⅡ,Ⅲ,Ⅳclassification according to their cardiac function(NYHA classification). HF group was also divid?ed into normal renal function group, mild renal injury group and moderate-severe renal injury group based on their Ccr. Ef?fect of gender and lipid parameters were also compared. Binary logistic regression was used to analyze factors influencing renal function in patients with HF. Results Compared with people in the control group, the levels of triacylglycerol(TG), total cholesterol(TC), low density lipoprotein cholesterol(LDL-c)and non high density lipoprotein cholesterol(non-HDL-c)in patients of HF group were increased while Ccr and high density lipoprotein cholesterol(HDL-c)were decreased. Ccr and lipids were obviously decreased in patients with HF of Ⅳclassification. TG and HDL-c were decreased in moderate-severe renal injury group. Females had a higher lipid levels than males in HF group(P<0.05 or P<0.01). Advanced age, coronary heart disease and hypertension were all risk factors for renal impairment in patients with HF by binary logistic re?gression. On the other hand, weight gain and HDL-c were the protection factors for renal function in HF patients. Conclu?sion Dyslipidemias may lead to renal insufficiency in patients with HF. It was important to control lipids and improve re?nal function in patients with HF.

Objective To observe effects of intranasal sufentanil on analgesia.Methods Eighty-two patients,who scheduled for selective thyroidectomy were randomly divided into the observed group and the control group with 41 cases in each group.In the observed group,patients received intranasal sufentanil 20 μg before the incision about 10 minutes,then administered local infiltration with 0.5% lidocaine.In the control group,patients received water for injection which was placebo instead sufentanil.By double blind method observed verbal mting scale(VRS)score.The values of NBP,HR,SpO2 and respiration rate(RR)were recorded before intranasal drugs and 5,10,20,40,60 min after intranasal drugs.The amount of local anesthetic,the size of thyroid gland,the time of operation and the satisfaction were compared between the two groups.Nausea vomiting and pruritus were also observed in order to assess the safety of intranasal sufentanil.Results All patients completed the operation successfully.The RR in the observed group decreased to(13.1±0.5),(13.8±0.6),(13.8±0.8)times/min after intranasal sufentanil 10,20,40 min,and had significant difference with those before intranasal drugs(P＜0.05),anastated after 60 min.VRS score of the observed group was(2.0±0.4)scales,less than the control group,and had significant difference when the surgeon was dissecting thyroid gland(P＜0.05).The amount of local anesthetic in the observed group was(42.5±6.9)ml,less than the control group(63.7±4.3)ml(P＜0.05).The satisfaction had significant difference between the two groups(P＜0.05).Conclusion Intranasal sufentanil for analgesia is a safe and useful technology.
