Ostial lesions present many challenges for percutaneous coronary intervention (PCI). Coronary anomaly will further increase difficulties in performing PCI for the patient. We present such a case as ostial occlusion of an right coronary artery with high takeoff. A 77-year-old male was referred to our institution with a diagnosis of non-ST elevated acute myocardial infarction. Selective coronary angiography and nonselective ascending aortography could not identify the origin of the right coronary artery. Multi-slices computed tomography showed RCA ostial totally occluded. A successful PCI was performed and a perfect final result was achieved utilized with many tips and tricks, including buddy wire technique and focused-force angioplasty.

Objective To explore the effect of developed operating instrument set for cesarean section. Methods Toally 216 parturients to undergo cesarean section in our hospital during May to December 2014 , were divided into observation group and control group, 108 cases in each group:in the observation group the developed operating instrument set was used and in the control one, the routine operating instrument set was used. The two groups were compared in terms of contamination rate and the time for postoperative operating room preparation. Results The contamination rate of the observation group was significantly lower than that of the control group (P<0.01). The time for postoperative operating room preparation of the observation group was significantly shorter than that of the control group (P < 0.01). Conclusion The developed operating instrument set can reduce the rate of contamination at the operated area during cesarean section and shortned the time for postoperative operating room preparation , thus enhancing the work efficiency.

Vaspin,a serine protease inhibitor derived from visceral adipose tissue,has been identified as an adipokine with insulin-sensitizing effects in a rat model of type 2 diabetes.Recent studies showed that the administration of recombinant human vaspin significantly improved insulin sensitivity and glucose tolerance,and reversed the expression of genes that may promote insulin resistance in diet-induced obese mice.However,the regulation of serum vaspin concentration in individuals with insulin resistance,and the association of vaspin with obesity,type 2 diabetes,and insulin resistance related disorders remain unclear.

Brain-derived neurotrophic factor (BDNF)is both a neurotrophic substance and a neurotransmitter.BDNF and its receptors are highly expressed in enteric nervous system,intestinal mucosal epithelium and intestinal muscularis, which play an important role in regulating intestinal sensitivity and motility.This article reviewed the expression and role of BDNF in intestinal tract.

Objective To investigate the effect of interleukin-17 (IL-17) in the gastric cancer cell migration and invasion via regulating epithelial-mesenchymal transition (EMT) and its potential function.Methods (1) Human gastric cancer cell MGC-803 lines in the logarithmic growth phase were stimulated by 0, 1 ng/mL, 10 ng/mL,100 ng/mL and 1μg/mL of IL-17 for 48 hours, and the phenotypic changes were observed.The concentration of IL-17 was selected for follow-on experiments based on the most obvious phenotypic changes.Gastric cancer cell MGC-803 which were stimulated by 100 ng/mL of IL-17 and PBS for 48 hours were allocated into the experimental group and control group, respectively.(2) The expressions of E-cadherin and Vimentin mRNA in gastric cancer cells were assayed through real-time PCR (RT-PCR).(3) The relative expressions of E-cadherin and Vimentin proteins in gastric cancer cells were assayed by the Western blot.(4) The scratch test and Transwell detection were also utilized to study the migration and invasion of gastric cancer cell MGC-803 in vitro.Measurement data with normal distribution were presented as-x ± s and comparison between groups was analyzed using the t test.Results (1) There were significant phenotypic changes in the gastric cancer cell after the different concentration of IL-17 stimulated gastric cancer cell MGC-803 for 48 hours.Cells were changed from polygonal and tight junction to spindle and loosely junction with a deterioration of cell adhesion.Cell phenotypes were gradually changed as the concentration of IL-17 was changed from 0 to 100 ng/mL.Phenotypic changes were the most obvious when 100 ng/mL of IL-17 was used, but these were non-significant as the concentration of IL-17 increased to 1 μg/mL with the death and floating of some cells.(2) The relative expressions of E-cadherin mRNA and Vimentin mRNA in RT-PCR were 0.45 ±0.13 and 1.06 ±0.23 in the experimental group and 2.39 ±0.55 and 1.23±0.41 in the control group, respectively, with significant differences (t =3.811, 2.923, P ＜0.05).(3) The results of Western blot showed the relative expressions of E-cadherin and Vimentin proteins were 0.86 ± 0.17 and 1.56 ± 0.29 in the experimental group and 1.01 ± 0.12 and 0.56 ± 0.17 in the control group, respectively, with significant differences (t =3.551, 3.601, P ＜ 0.05).(4) Cell migration in the 2 groups were detected by the scratch test at 36 hours after scratch test, and the width of scratch in the experimental and control groups were (0.76 ± 0.13) mm and (0.40 ± 0.15) mm, showing a significant difference (t =3.095, P ＜ 0.05).Transwell detection showed number of transmembrane cell in the experimental and control groups were 159 ±28 and 94 ± 18, respectively, with a significant difference (t =3.307, P ＜ 0.05).Conclusion IL-17 can promote the migration and invasion of gastric cancer cells via stimulating alteration of EMT.

Objective To investigate the clinical effect of tension-free hernia repair in the treatment of inguinal hernia combined with ascites.Methods The retrospective cross-sectional study was conducted.The clinical data of 81 inguinal hernia patients with ascites who were admitted to the West China Hospital of Sichuan University from June 2008 to June 2014 were collected.Patients with peritoneal effusion received restriction of sodium in take and diuretic therapy,and patients with severe hypoproteinemia received intravenous injection of albumin.All the patients underwent tension-free hernia repair (Gilbert way).Observation indicators:(1) surgical and postoperative situations:operation time,diameter of hernia ring,defect area of hernia,postoperative plasma drainage,removal time of plasma drainage-tube,postoperative complications and duration of hospital stay;(2) follow-up situation:recurrence and long-term complications of inguinal hernia.Follow-up using telephone interview,outpatient examination and inpatient examination was performed to detect the hernia recurrence and long-term complications for 24 months up to June 2016.Measurement data with normal distribution were represented as (x)±s.Results (1) Surgical and postoperative situations:81 inguinal hernia patients with ascites underwent successful tension-free hernia repair.The operation time,diameter of hernia ring and defect area of hernia were respectively (46± 19) minutes,(3.1-± 0.7) cm and (25 ± 13) cm2.Sixty-five patients received indwelling plasma drainage-tube after repair,volume of light bloodstained fluid was respectively ≥ 100 mL in 39 patients and ＜ 100 mL in 26 patients at 24 hours postoperatively,with a removal time of plasma drainage-tube of (3.2± 1.0)days.Sixteen patients didn't receive indwelling plasma drainage-tube.Of 81 patients,9 and 4 were respectively complicated with mild seroma of incision and scrotal swelling,they were improved and then out of hospital after adequate drainage,with a duration of hospital stay (6.7-± 1.7)days.(2) Follow-up situation:of 81 patients,76 were followed up for 24 months,without recurrence and related complications of inguinal hernia.Conclusion The tension-free hernia repair in the treatment of inguinal hernia combined with ascites is safe and feasible,with good clinical effects.

objective To evaluate the vulnerability of coronary artery plaque with coronary angiography(CAG),intravascular ultrasound(IVUS)and the levels of plasma inflammatory markers.Methods 58 consecutive patients with lesion of a single blood vessel demonstrated successfully by CAG were randomly divided into 3 groups based on the angiographic morphology of the the lesions:type Ⅰ lesion group(n=16),type Ⅱ lesion group(n=25),type Ⅲ lesion group(n=17).Meantime,a control group of stable angina(n=17)was established.A subgroup of 28 patients(including 18 acute coonary sysdrome (ACS)patients and 10 stable angina control patients)who underwent IVUS study were analyzed.Then the plasma levels of high sensitivity CRP(hs-CRP),matrix metalloproteinase(MMP,including MMP-2 and MMP-9),CD40 ligand(CD40 L)and pregnancy associated plasma protein-A(PAPP-A)were measured with ELISA.Analyses were performed by statistical package SPSS 11.0.Results The plasma levels of MMP-2,MMP-9 and PAPP-A in typeⅡ lesion group were significantly higher than the other groups(P＜0.05,0.05,0.001,respectively).In type Ⅱ lesion group,linear correlation analysis manifested significantly positive correlation between levels of hs-CRP and MMP-2(r=0.508);MMP-2 and MMP-9,CD40 L,PAPP-A(r=0.647,0.704,0.751,respectively);MMP-9 and CD40L,PAPP-A(r=0.491,0.639,respectively);CD40L and PAPP-A(r=0.896).IVUS subgroup analysis showed that the area of plaques and plaques burden in culprit lesion,the incidence of high-risk plaques,remodeling index(RI)and positive remodeling percentage in ACS patients were significantly greater than those in the control group(P=0.000,0.037,0.028,0.015,0.040,respectively).Compared with the control group,the plasma levels of hs-CRP,MMP-2,MMP-9 and PAPP-A were markedly elevated(P=0.033,0.000,0.000,0.027,respectively).Conclusions CAG and IVUS combined with the study on plasma levels of inflammation mediators were helpful in judging the vulnerability of coronary artery plaques.

BACKGROUND: The association of tumor necrosis factor alpha (TNF-α) gene polymorphisms with the onset and development of ankylosing spondylitis (AS) has been the focus of studies on AS in the field of genetics.OBJECTIVE: To explore the association of the polymophisms of TNF-α promoter gene at positions-308 and -238 with AS susceptibility and clinical pathological changes.DESIGN: A case-control study.SETTING:The Rheumatic Immunology Department of Changhai Hospital of the Second Military Medical University of Chinese PLA.PARTICIPANTS: Totally, 108 AS patients were recruited from Rheumatic Immunology Department of Changhai Hospital, Second Military Medical University of Chinese PLA from January 1999 to December 2003 ,they had no kinship. The ratio of men to women was 5.3: 1. They aged from 13 to 71 (30-± 12) years old, and AS was divided into Ⅰ- Ⅳ radiographic stages according to the sacro-iliac joint damage. A total of 100 healthy controls were randomly selected from the blood donators(Shanghai Hospital) who were aged from 19 -56 (33 ±9) years old, and the ratio of men to women was 4.9: 1. Informed consent was obtained from all the subjects.ti-coagulated with EDTA. Polymerase chain reaction amplification and purification of the TNF-α promoter region was made and the sequence of polymerase chain reaction products was examined and displayed by Chromas 1.62 softcorresponding radiographic stage of sacro-iliac joint damage was assessed to investigate the influence of gene polymorphisms on AS.MAIN OUTCOME MEASURES: DNA direct sequencing method was used to detect -238 and -308 allele phenotypes for investigating the association with clinical presentations.G and -238G/A allele was 98.1% (106 cases) and1. 9% (2 cases) respectively in AS group and 95.0% (95 cases) and 5.0% (5 cases) respecquency of TNF-α promoter gene at positions -308. 1.1(G/G) and - 308.1.2(G/A) alleles was 82.4% (89 cases) and 17.6% (192 cases) respectively in AS group, which was not significantly different compared respectively with 85.0% (85 cases) and 14.0% (14 cases) of the control of sacro-iliac joint damage and the frequency of TNF-α promoter gene at the position of - 308 (G/G) and (G/A): AS patients with(G/G) phenotype who were confirmed of radiographic stage Ⅰ, Ⅱ, Ⅲ, and Ⅳ were observed in 3/35/40/11cases,compared with (G/A) phenotype of 1/12/6/0 cases.The difference was statistically significant (χ2GMH = 4.77, P ＜ 0.05 ).CONCLUSION: Our data suggest that the polymorphisms of TNF-α promoter gene at positions of - 238 and - 308 allele has no association with AS susceptibility, but the polymorphisms of TNF - α promoter gene at the position of -308 might exert great influence on AS according to the radiographic stage of sacro-iliac joint damage.
