Background:Studies have shown that patients with peptic ulcer are susceptible to the accompanying of anxiety and depression,and affects the treatment of ulcer. Aims:To study the effect of flupentixol and melitracen combined with quadruple therapy on peptic ulcer patients with anxiety and depression. Methods:Sixty-eight peptic ulcer patients with anxiety and depression from May 2012 to May 2013 at Wuhu No. 2 People’s Hospital were enrolled,and were randomly divided into control group and observation group. Patients in control group were given quadruple therapy( rabeprazole 20 mg + amoxicillin 1. 0 g + clarithromycin 0. 5 g + colloidal bismuth subcitrate solution 10 mL,bid),while patients in observation group were given flupentixol and melitracen in addition to quadruple therapy,the treatment course were both for 2 weeks. Therapeutic efficacy of ulcer,Helicobacter pylori( Hp) eradication,therapeutic efficacy of anxiety and depression,incidence of adverse reaction and recurrence rate of ulcer within one year after treatment were compared between the two groups. Results:Compared with control group,the therapeutic efficacy of ulcer and Hp eradication in observation group were significantly increased(P < 0. 05),therapeutic efficacy of anxiety and depression was significantly increased(P < 0. 05),no significant difference in the incidence of adverse reaction was found between the two groups,and the recurrence rate of ulcer within one year was significantly decreased( P < 0. 05). Conclusions:Flupentixol and melitracen combined with quadruple therapy could significantly improve the therapeutic efficacy and effectively reduce the recurrence rate in peptic ulcer patients with anxiety and depression.

Lappaconitine hydrobromide can remove inflammation and swelling, lower temperature and relieve heat. It also can be used for local anesthesia. Clinically lappaconitine hydrobromide can be applied via i.v., i.m. or p.o. for analgesic treatment. Lappaconitine has better effect for moderate pain than for severe pain, which may be associated with the low dose. Future efforts should be made in increasing dosage, combining lappaconitine hydrobromide with other drugs and improving drug delivery technique.

The present paper is to analyze the trend of sinus heart rate RR interphase sequence after a single ventricular premature beat and to compare it with the two parameters, turbulence onset (TO) and turbulence slope (TS). Based on the acquisition of sinus rhythm concussion sample, we in this paper use a piecewise linearization method to extract its linear characteristics, following which we describe shock form with natural language through cloud model. In the process of acquisition, we use the exponential smoothing method to forecast the position where QRS wave may appear to assist QRS wave detection, and use template to judge whether current cardiac is sinus rhythm. And we choose some signals from MIT-BIH Arrhythmia Database to detect whether the algorithm is effective in Matlab. The results show that our method can correctly detect the changing trend of sinus heart rate. The proposed method can achieve real-time detection of sinus rhythm shocks, which is simple and easily implemented, so that it is effective as a supplementary method.

To study the quantitative detection method of T-wave alternans (TWA), we analyzed the relationship between the graphic mode of Poincare scatter and TWA, and proposed 'horizontal search algorithm' to complete graphic processing. Then, based on the shape of Poincare scatter, we took Axial_ratio as the final index. Through Matlab simulation, Axial_ratio was compared with the results of spectral method (SM) and appropriate threshold value was selected to recognize the TWA. The results showed that Axial_ratio could accurately detect the TWA.

Objective To investigate the risk factors of biliary tract complications in patients with liver cancer after thermal ablation and the prevention methods.Methods One thousand seven hundred and ninety-seven patients with liver cancer underwent percutaneous thermal ablation were enrolled in this retrospective study.According to the relative position of the tumor and biliary tract,patients were classified into 4 groups:with the tumor close to the first branch (group Ⅰ),the second branch (group Ⅱ),the third branch of bile duct (group Ⅲ) and far away from the biliary tract (group Ⅳ).The tumor response and complications,especially biliary tract complications after ablation therapy of subgroups were analyzed.Results A total of 2 356 sessions were performed in 1 797 patients with 3 200 lesions.The local progression rates of the tumors close to and far away from biliary were 10.0 ％ and 8.2 ％ (P =0.080) and the rate of complete ablation were 96.5 ％ and 97.2 ％ (P =0.298),respectively.Fourteen patients suffered from major biliary complications after thermal ablation.Biliary complication incidences of the patients with the tumor close to the first,the second biliary tract were 6.5 ％ and 2.9 ％ respectively,which were all higher than those of the patients with the tumor close to the third(0.3％) and far away from biliary duct(0.2％).Conclusions Percutaneous thermal ablation is an efficient and safe method in the treatment of tumors close to biliary tract and with a low incidence of major biliary complications.Patients with a tumor close to the large branch of biliary duct were at high risk of complications.Those tumors,therefore,should be ablated with assisting methods and extra care.

Objective To investigate the accuracy and availability of three‐dimensional ultrasonography ( 3DUS ) in the Bismuth‐Corlette classification of hilar cholangiocarcinoma ( HCCA ) . Methods Forty‐eight patients who underwent surgery and obtained pathologic diagnosis of HCCA were retrospectively analyzed . All patients underwent 3DUS and magnetic resonance cholangiopancreatography (MRCP) before surgery . With surgical outcomes as the gold standard ,the diagnostic efficacy of two examinations in classification of HCCA were compared . Results Forty‐eight cases of HCCA were divided into 5 types according to surgical results ,including type Ⅰ (8 cases) ,type Ⅱ(13 cases) ,Ⅲa(8 cases) ,Ⅲb (11 cases) and type Ⅳ(8 cases) respectively . Among them ,39 cases accepted radical resection and the rest of 9 cases received palliative resection . The accuracy of the Bismuth classification confirmed by 3DUS was 85 .4% (41/48) . The percentage of underestimated and overestimated classification confirmed by 3DUS were 10 .4% (5/48) and 4 .2% (2/48) respectively . The accuracy of the classification confirmed by MRCP was 87 .4% (42/48) .Both of the percentage of underestimated and overestimated classification confirmed by MRCP were samely 6 .3% (3/48) .The difference between the 3DUS and MRCP was not statistically significant(χ2 =0 .597 ,P=0 .440) . Both the percentage of underestimated and overestimated classification between 3DUS and MRCP were samely not statistically significant ( P =0 .714 , P =1 .000 ,respectively) .

Objective A prospective randomized controlled trial was carried out to explore the best time of In-domethacin suppositories administration for the prevention of post-ERCP pancreatitis in high-risk groups. Methods 81 patients were enrolled in the study finally. Patients were randomized into group A (100 mg rectal Indomethacin suppositories was administrated immediately after ERCP), group B (100 mg rectal Indomethacin suppositories was administrated half an hour after ERCP) and group C (ERCP alone group, which did not give Indomethacin supposito-ries). The level of serum amylase, urine amylase, serum CRP, serum IL-6, serum TNF-α were measured before, 3 h, 24 h and 48 h after ERCP, and the incidence of PEP and hyperamylasemia were analyzed. Results There was 1 case (4.00%) of PEP in group A, 2 cases (5.41%) of PEP in group B and 5 cases (26.31%) of PEP in group C;the incidences of PEP of group A and group B were significant lower than that in group C (P < 0.05). There was 1 case (4.00%) of hyperamylasemia in group A, 5 cases (13.51 %) of hyperamylasemia in group B and 6 cases (31.6 %) of hyperamylasemia in group C, and the incidences of hyperamylasemia of group A and group B were significant lower than that in group C ( P< 0.05). Conclusion Administration of 100 mg Indomethacin suppositories immediately or half an hour after ERCP can effectively reduce the incidence of PEP and hyperamylasemia.

Objective To clarify whether Helicobacter pylori (H. pylori) can promote metastasis of gastric cancer cells via the high-expression of induced B cell specific Moloney murine leukemia virus integration site 1 (Bmi-1). Methods The gastric cancer tissue specimens from 82 patients were collected for this study. The protein and gene expression level of Bmi-1 in gastric adenocarcinoma tissue were detected by immunohistochemistry and real time quantitative PCR, respectively. And meanwhile the correlation between Bmi-1 levels and pathological features, and prognosis of gastric cancer were analyzed retrospectively. Then, the GES-1 cells were transfected with pLPCX-Bmi-1 plasmid and infected with H. pylori respectively. After the Bmi-1 overexpression in GES-1 cells, the invasion ability of the GES-1 cells was detected by Transwell assay, and the cell cycle and apoptosis were detected by flow cytometry. Results The mRNA and protein of Bmi-1 expression in gastric cancer tissues were higher than tumor-adjacent tissue, and the high expression of Bmi-1 was positively correlated with tumor invasion, TNM stage, tumor differentiation, lymph node metastasis and H. pylori infection. When expression of Bmi-1 was up-regulated as a result of H.pylori infection or pLPCX-Bmi-1 transfection, the GES-1 cells had higher invasiveness and lower apoptosis rate with the above treatment respectively. Conclusion H. pylori infection can inhibit the apoptosis of gastric cancer cells and promote their invasion via up-regulating expression of Bmi-1.
