Objective To investigate the correlation of the prevalence of periodontitis with age and course of disease in patients with type 2 diabetes.Methods A total of 884 patients with diabetes (both sexes,aged 35-79 yr) were involved in present study.Diagnosis of periodontitis was made according to the 1999 WHO standard,and of type 2 diabetes to the 1997 WHO standard.Age,gender,course of diabetes and periodontal state of those patients were recorded.The patients were grouped according to their age (10 yr interval) and course of disease (5 years interval).Based on the grouping,the collected data were input into ACCESS data bank and statistically analyzed with SAS software,and the prevalence of periodontitis were then compared.Results The prevalence of periodontitis in patients with type 2 diabetes increased with the increasing of age and with the prolonging of disease course (P

Objective To investigate the efficiency of transjugular intrahepatic portosystemic shunt (TIPS) with Fluency stent in improving the hepatic and renal function and survival rate in patients with decompensated cirrhosis.Methods The decompensated cirrhosis patients who were treated in our hospital from May 2008 to September 2011 were retrospectively analyzed.One group of patients (n =48) undergoing TIPS was randomly selected as treatment group,while another group of patients (n =48) treated by medicine and therapeutic endoscope was randomly chosen as control group.Clinical data and fellow-up data were retrospectively reviewed.There was no significant deviation in baseline characteristics (age,gender composition,etiology,renal function,hepatic function et al) among all the patients before the operations; The laboratory results of hepatic and renal function in 2 groups before and after operation (1 week,20 days,3 months,6 months,1 year,2 years,3 years) were recorded and compared with independent samples t-test or Wilcoxon rank sum test.The survival rates of two groups in 3 years were analyzed using Kaplan-Meier survival curve and compared with Chi-square test.Results Three years after the operation,there were significant differences between the treatment group and the control group in AST(70.8 vs.108.7 U/L,Z =-2.958,P ＜ 0.05) and TBIL (51.2 vs.76.2 μmol/L,Z =-2.004,P ＜ 0.05).The Cr value of the 3rd year after the treatment were (9928.2 ± 2363.8) in the the control group and (7742.1 ± 2845.6) μmol/L in the treatment group(t =-2.074,P ＜ 0.05).BUN of the 1st,2nd and 3rd years after the treatment were (2.0 ± 1.1),(2.3 ± 1.5),(2.5 ± 1.3) mmol/L in the treatment group,while it was (2.6 ± 1.1),(3.8 ±1.2),(5.4 ± 1.1)mmol/L in the control group.There was significant difference between the 2 groups (t =-2.222,-3.940 and-6.110,P ＜ 0.05).Comparing the survival rate in the 2 groups with Kaplan-Meier survival curve,the 3 year survival rate in the treatment group was 46.2％,while in the control group it was only 30.0％ (x2 =6.341,P ＜ 0.05).Conclusions Compared with medicine therapy and therapeutic endoscopy,TIPS with Fluency stent may improve the hepatic function,renal function and survival rate in liver cirrhosis patients.It is a safe and effective therapy choice for patients with decompensated cirrhosis.

Objective To evaluate the effect ofcytochrome P450 isoenzyme subfamily 2C19 (CYP2C19)gene polymorphism on the clopidogrel antiplatelet therapy in cirrhosis patients after receiving transjugular intrahepatic portosystemic shunt (TIPS).Methods The clinical data of 171 cirrhosis patients,who were treated with TIPS during the period from January 2013 to December 2014,were retrospectively analyzed.During operation both the portal vein and the elbow vein blood samples were collected and sent for CYP2C19 gene testing.After TIPS,clinical follow-up checkup was made once every 3 months.The gene detection results and clinical follow-up findings were comparatively analyzed.Results A total of 110 patients,who had not received blood transfusion before TIPS and who had regularly taken clopidogrel antiplatelet therapy after TIPS were enrolled in the study.The mean time to take clopidogrel was 192.4 days (31-517 days),and the gene detection results of portal vein and elbow vein were quite consistent.CYP2C19 genotype of *1/*1 was found in 49 patients (44.5％),CYP2C19 genotype of *1/*2 in 27 patients (24.6％),CYP2C19 genotype of *1/*3 in 18patients (16.4％),CYP2C19 genotype of *2/*2 in 11 patients (10.0％),CYP2C19 genotype of *2/*3 in 3patients (2.7％),and CYP2C 19 genotype of *3/*3 in 2 patients (1.8％).Following-up examinations showed that the incidence of shunt dysfunction in patients carrying slow metabolic gene was 87.5％ (14/16),which was significantly higher than that in patients carrying moderate metabolic gene (20.0％,9/45;x2=22.9,P=0.006)as well as in patients carrying fast metabolic gene (8.2％,4/49;x2=37.91,P=O.O00 1).Multivariate analysis of Cox regression model indicated that CYP2C19 slow metabolic gene variation was an important predictive factor for shunt dysfunction (95％CI:1.80-9.03,P=O.O00 7).Conclusion CYP2C19 slow metabolic gene variation,including genotype of *2/*2,*2/*3 and *3/*3,is an important factor that can influence the efficacy of clopidogrel treatment after TIPS.Preoperative CYP2C19 gene detection results can provide useful information,which is very helpful in making an effective and reliable anti-platelet treatment plan for patients after TIPS.

Objective To evaluate the curative effect,safety,and medium-term effect of intracranial artery stenosis stent (ICASS) for the treatment of the symptomatic intracranial artery stenosis.Methods ICASS was performed in 21 cases with the symptomatic intracranial artery stenosis.The stenting success rate,the improvement rate of stenosis post-stenting and the incidence of complications were observed.The change of the scores of the Modified Rankin Scale (MRS)and National Institutes of Health Stroke Scale (NIHSS)between pre-and post-stenting (1 month,3 months,6 months,12 months and 2 years)and the occurrence of ischemic cerebrovascular events after stenting were compared and analyzed respectively.Results Except one case failed because of intracranial hemorrhage during the operation,other 20 patients were treated with endovascular stent plasty successfully,the total technical achievement ratio was 95.2%.The aver-age stenosis ratio decreased from (73.4±7.9)% to (13.7±9.2)%.The complications incidence was 4.8% within the peroperative. 9 patients were reviewed with DSA in 6 months,the average ratio of stenosis was (29.5 ±12.2)%,no patient was found with the restenosis.Compared with pre-stenting,the score of MRS and NIHSS at the follow-up duration of 3 months,6 months,12 months and 2 years post-stenting of patients were significant improved (all P < 0.05 ).During the follow-up period,2 patients were found with new transient ischemia attack (TIA),1 patient had non-targeted vascular CI without other target vascular therapy-related com-plications.Univariate analysis indicated that patients with elderly (≥ 75 years old),or hypertension,or diabetes,or dyslipidemia,or in the set of events to endovascular treatment for longer than 1 month,or with more than two independent risk factors for patients with underlying diseases treatment,or without systemic therapy,whom would be much more easily to reoccur the cerebrovascular events in post-operation(all P <0.05 ).Conclusion ICASS should be an effective and safe therapeutic method to the symptomatic intracra-nial arterial stenosis.The medium-term efficacy is significant.Serious complications might still be emerge with endovascular stent plasty,so close attention must be paid with.

Objective Through detecting the genotypes of vascular endothelial growth factor (VEGF) to investigate the correlation between the different VEGF genotypes and survival rate of patients with hepatocellular carcinoma (HCC) after receiving transcatheter arterial chemoembolization (TACE). Methods A total of 156 patients with pathologically confirmed HCC, who were admitted to authors’ hospital during the period from January 2008 to January 2009 and received TACE within 2 months after the disease was confirmed by pathology, were included in this study. The genotypes of VEGF-2578C/A, -1154G/A, -634C/G, and-1498T/C were determined using a blood kit on a 384-well plat. The clinical data were collected, and the correlations between the genotypes and the patient’s prognosis were analyzed. Results In this study, a total of four genotypes were detected, including VEGF-2578C/A, VEGF-1154G/A, VEGF-634C/G and VEGF-1498T/C. The mean 5-year survival rate was 55.47%. Multivariate analysis revealed that only the tumor-node-metastasis(TNM) stage, metastasis, and the VEGF-2578 AA and VEGF-1154 AA genotypes were independent prognostic factors. HCC of TNM stage Ⅲ-Ⅳ would greatly increase the risk of death in HCC patients (HR=3.64, 95%CI=1.67-6.79; HR=2.91, 95%CI=1.30-6.27). Moreover, the death risk in patients with the VEGF-2578 AA and VEGF-1154 AA genotypes was much higher than that in patients with the wild-type genotype (HR=3.65, 95%CI=1.35-11.13; HR=7.13, 95%CI=1.46-65.8). Conclusion VEGF-2578C/A genotype and VEGF-1154G/A genotype are closely related to the prognosis of HCC patients after TACE treatment, which may be helpful for predicting the clinical outcome of HCC patients after interventional treatment.

Objective To investigate the clinical characteristics of hemodialysis (HD) patients complicated with arteriosclerosis obliterans (ASO) of lower extremity,and to discuss the factors that influence the curative prognosis of percutaneous transluminal angioplasty (PTA).Methods The clinical data of 211 patients with ASO of lower extremity receiving HD or not receiving HD,who were admitted to authors' hospital during the period from January 2008 to October 2015,were retrospectively analyzed.PTA was successfully accomplished in all patients.Results The median follow-up time was 2.24 years.Theamputation-free survival of HD group was significantly lower than that of non-HD group (P＜0.000 1),and the postoperative artery patency rate of HD group was also obviously lower than that of non-HD group (P＜0.000 4).The factors influencing the survival rate without amputation of the two groups were different.The independent influence factor in HD group was diabetes mellitus,while in non-HD group the independent influence factors were Fontaine stage and hyperlipidemia.The infection mortality of HD group was 55.5％ (10/18),which was higher than 22.2％(6/26) of non-HD group,the difference was statistically significant (P＜0.05).Conclusion In treating ASO of lower extremity,the curative effect of PTA is poorer in HD patients than in non-HD patients,and the presence of diabetes mellitus may be an independent factor influencing prognosis.

Objective To investigate the curative effect of the preoperative intervention transcatheter arterial chemoembolization and preoperative intravenous systemic simple chemotherapy for gastric cancer.Methods Retrospective analysis of 55 patients diag-nosed with gastric cancer.These patients were divided into two groups:treatment group and control group (simple chemotherapy group),with treatment group of 35 cases and control group of 20 cases,and cases of two groups all received surgical radical surgery for gastric carcinoma treatment.Preoperative and postoperative clinical symptoms were observed.Data of tumor sizes and tumor vessel changes were analyzed and compared.The difference of curative effect between two groups was observed.Results Compared with control group,degeneration and necrosis of tumor cells in gastric cancer tissue of treatment group were obvious,and tumor ves-sels significantly reduced,with nonuniformed,and became thinner.Number of tumor vessels of treatment group was obviously low-er than that of control group (P <0.05).Conclusion The interventional therapy of gastric cancer has obvious short-term therapeutic effects,and can reduce tumor vessels effectively and improve surgical resection rate.

Objective To assess the validity and safety of arterial embolization with medical adhesive in treating peripheral artery pseudoaneurysms(PSA).Methods 25 cases of peripheral artery PSA embolized with Fuaile medical adhesive(FMA) were analyzed retrospectively.25 patients included 28 PSA.Super-selective transcatheter arterial embolization was performed in 19 patients (22 PSA) using 3F microcatheter and 6 PSA in 6 patients were embolized through puncturing directly.All the lesions were treated with mixtures of FMA and iodized oil (1：1) during the radiography.The clinical efficacy and complications were recorded.Results The success rate of embolization was 100% during the operation (28/28), and the average volume of FMA used was 1.8 mL(0.5-5.5 mL).One patient with PSA(d>2 cm) still have hematuria 2 days after the operation.The hematuria disappeared after embolization with micro-coil following re-angiography.Bleed stopped after the second embolization with FMA in one patient with brachial artery PSA.No one developed complications associated with therapy and occurred rebleeding in the follow-up period time (3 months).Conclusion The mixtures of FMA and iodized oil can be a useful alternative embolic agent for the treatment of peripheral artery pseudoaneurysm with high success rate, short operation time and definite clinical effect.

Objective To discuss the prognostic value of aspartate aminotransferase (AST) to neutrophils ratio index (ANRI) in patients with hepatocellular carcinoma (HCC) after receiving transarterial chemoembolization (TACE).Methods The clinical data of 107 HCC patients,who were admitted to authors' hospital to receive treatment during the period from January 2008 to June 2011,were retrospectively analyzed.TACE was successfully performed in all patients.Based on the 5-year overall survival rate,ROC curve was drawn and the cutoff value was determined.Preoperative ANRI,AST-lymphocytes ratio index (ALRI),AST-platelet count ratio index (APRI),neutrophil-lymphocytes ratio index (NLR),platelet count-lymphocytes ratio index (PLR) and other clinical pathological parameters were calculated.Univariate analysis,multivariate Logisitc regression analysis and Kaplan-Meier survival analysis were used to assess the value of the above indexes in prejudging the disease-free survival (DFS) and overall survival (OS).Results ANRI bore a close relationship to the presence of HBsAg,AST,presence of cirrhosis,tumor size,portal vein tumor thrombus (PVTT) and recurrence of tumor (P＜0.05).Univariate analysis showed that ANRI,ALRI,APRI,NLR and PLR were significantly correlated with DFS and OS in HCC patients after receiving TACE (P＜0.05).Logisitc regression analysis revealed that ANRI was independent factor influencing DFS and OS (P＜0.05).Kaplan-Meier survival analysis indicated that the prognosis after TACE was poor in patients whose preoperative ANRI ＞7.8.Conclusion Preoperative ANRI level is an independent and effective predictor for judging the prognosis of HCC patients.A high preoperative ANRI level usually suggests a poor prognosis after TACE.
