The conventional therapy for arteriosclerosis obliterans (ASO) is Western medicine. However, it has some adverse effects and does not respond to some patients, and it is also very expensive.

Objective To compare anatomic resection (AR) and non-anatomic resection (NAR)for hepatocellular carcinoma (HCC) as a factor in preventing intra-hepatic recurrence and local recurrence after the initial surgical procedure.Methods A systematic review and Meta-analysis of nonrandomized trials comparing anatomic resection with non-anatomic resection for HCC published from 1990to 2010 in PubMed and Medline,Coehrane Library,Embase,and Science Citation Index were searched.Intra-hepatic recurrence,including early and late recurrence,and local recurrence were primary outcomes.5-year survival and 5-year disease-free survival were secondary outcomes.Pooled effect was calculated by utilizing either fixed effects model or random effects model.Result Eleven nonrandomized studies including 1576 patients were identified and analyzed.810 patients were in the AR group and 766 were in the NAR group.Patients in the AR group were characterized by lower prevalence of cirrhosis,more favorable hepatic function,and larger tumor size and higher prevalence of macrovascular invasion compared with patients in the NAR group.Anatomic resection significantly reduced the risks of local recurrence (OR,0.27; 95％ CI,-0.17～0.43; P＜0.001) and achieved a better 5-year disease-free survival (OR,2.10; 95％ CI,-1.41 ～3.12; P=0.001) in HCC patients.Also,anatomic resection was marginally effective in decreasing early intra-hepatic recurrence.However,anatomic resection was not advantageous in preventing late intra-hepatic recurrence.No significant differences were found between the AR and NAR groups with respect to postoperative morbidity,mortality,and length of hospitalization.Conclusion Anatomic resection was recommended to be superior to non-anatomic resection in reducing the risks of local recurrence,early intra-hepatic recurrence and achieving a better 5-year disease-free survival in HCC patients.

A new HPLC-UV technique for the separation and analysis of 10 monosaccharides achieved within 13.5 min using 1-phenyl-3-methyl-5-pyrazolone (PMP) as the labelling molecule of the reductive monosaccharides has been established by combining common high performance liquid chromatography-UV and C18 column. The established technique was applied to the quantification of the monosaccharide components in extract of Silybum marianum. The results showed that the tested 10 monosaccharides as PMP derivatives were baseline separated under the HPLC conditions proposed. It was confirmed that Silybum marianum extract was composed of mannose, rhamnose, glucuronic acid, galacturonic acid, glucose, xylose, galactose and arabinose with the molar ratio of 0.66:0.84:0.58:1.0:1.6:0.69:2.7:4.8. Quantitative recoveries of the compositional monosaccharides separated from the extract were in the range of 92.4%-104.0%, and the RSD values fell within 0.68%-3.81%. The results demonstrated that the proposed HPLC method was simple, rapid, convenient, and precise, and it was applicable to the analysis of the compositional monosaccharides of Silybum marianum extract.

Objective To investigate the effects of simethicone on the quality of video capsule endoscopy (VCE) examination.Methods A prospective study was performed in 90 patients received VCE examination from February 2010 to October 2014.The randomized table was set according to different dosage of simethicone the patients received,by which patients were divided into three groups.Group 1 (35 cases) received 15 mL simethicone,group 2 (30 cases) received 30 mL simethicone and control group (25 cases) received no simethicone.The small intestinal visualization quality of VCE was scored by segments.Segment A was proximal small intestine (one hour after VCE passing pylorus).Segment B was distal small intestine (one hour before VCE passing ileocecal valve).Segment A and B were scored according to the air bubbles and degree of cleanliness.Gastric transit time,small bowel transit time and VCE completion rate were recorded.Student's t test,Mann Whitney rank sum test and chi square test were performed for statistical analysis.Results The average scores of segment A of group 1,group 2 and control group were 0.58,0.33 and 1.67,respectively,and the average socres of segment B were 0.25,0.00 and 1.17,respectively.The lesion detection rates of group 1,group 2 and control group were 68.6％ (24/35),80.0％ (24/30) and 52.0％ (13/25),respectively,and the differences was statistically significant (x2 =8.238,P=0.016).The detection rate of group 2 was significantly higher than those of group 1 and control group (x2 =7.354 and 9.349,P=0.034 and 0.005).The detection rates of small intestinal erosion of group 1,group 2 and control group were 22.9％ (8/35),70.0％ (21/30) and 32.0％ (8/25),respectively,and the differences was statistically significant (x2=8.714,P=0.013).The detection rate of group 2 was significantly higher than those of group 1 and control group (x2 =10.600 and 7.380,P=0.005 and 0.025).There was no statistically significant difference in the detection rates of ulcer,vascular malformation and protrusion among the three groups (all P＞0.05).The detection rates of lesions＜0.5 cm of group 1,group 2 and control group were 37.1％ (13/35),66.7％ (20/30) and 32.0％ (8/25),respectively,and the differences was statistically significant (x2 =8.242,P=0.016).The detection rate of group 2 was significantly higher than those of group 1 and control group (x2 =9.250 and 7.842,P =0.011 and 0.017).Conclusion Oral adminstration of 30 mL simethicone could obviously decrease air bubbles in small intestine,and increase lesion detection rate of VCE.

SUMMARY Behcet’sdisease(BD)isachronicvascularinflammatorydiseaseofunknowncauses.Itis called intestinal BD,when digestive tract is involved.To investigate small bowel feature of intestinal BD, we now report 5 intestinal BD cases undergone capsule endoscopy from December,2010 to April,2014 in Peking University People’s Hospital.General information,clinical feature and endoscopic feature were presented,and literatures were reviewed.There were 3 male and 2 female patients.Age range was from 23 to 55 years old (median age 40 years old).Disease course was from 3 days to 28 years (median course 9 years).4 patients were diagnosed as systemic BD,and the rest independent intestinal BD.4 systemic BD patients all presented as recurrent oral aphthous as initial symptom and had history of vulvar ulcer and skin lesion.They all had gastrointestinal symptoms,including retrosternal pain (2 cases),he-matochezia (3 cases),diarrhea (3 cases)and abdominal pain (2 cases).1 patient had a history of fis-tula of ileocecal junction and underwent caecectomy.5 patients all underwent whole digestive tract exami-nation by endoscopy,including gastroscopy,colonoscopy and capsule endoscopy.Except of 1 normal re-sult of colonoscopy,all endoscopy results revealed lesions.Capsule endoscopy results of all patients were abnormal.Types of small intestinal lesion were various,including ulceration,erosion,protrusion and vasculopathy.All digestive tract can be involved in BD patients.Capsule endoscopy can evaluate lesions throughout whole digestive tract,especially in small intestine.As a consequence,it is helpful to explain gastrointestinal symptom,increase early diagnostic rate.Intestinal BD (IBD)mainly involves small bow-el,and ileum is the major involved segment,not only limited in ileocecum.The updated perspective of IBD lesion distribution will contribute to differential diagnosis between IBD and Crohn’s disease.This is the first time to report capsule endoscopic feature of BD patients in China.

Background and purpose: The proportion of hepatocellular carcinoma (HCC) patients with cirrhosis and portal hypertension (PHT) is high. PHT may increase the risk of hemorrhage and liver failure. The aim of this study was to evaluate the safety and efifcacy of liver resection (LR) for patients with HCC and PHT. Methods:From 2006 to 2010, a total of 564 HCC patients with Child-Pugh A liver function and with (78) or without PHT (486) were retrospective analyzed. Complications after surgry, 30 and 90-day mortality, overall survival (OS), and recurrence rates were compared between the two groups. Propensity score analysis was also conducted to reduce confounding bias between the groups. Moreover, subgroup analysis based on tumor stage and the range of resection was carried out. Results:The complications after surgry, 30 and 90-day mortality of patients with PHT were signiifcantly higher than those without PHT, before and after propensity analysis (P<0.05). After an average follow-up of 32.1 months, the 1-, 3-, 5-year OS of patients with PHT (75%, 45%and 32%) were signiifcantly worse than those without PHT (90%, 66%and 48%;P<0.001). However, the 1-, 3-, and 5-year recurrence rates were similar between PHT group (31%, 57%, and 73%) and without PHT group (26%, 53%, and 67%;P=0.53). Moreover, the OS of the two groups were similar after propensity analysis, and for patients with early stage HCC and those who underwent minor hepatectomy (all P>0.05). Conclusion: PHT is not the contraindication of LR for patients with HCC. Those with early stage HCC and who underwent minor hepatectomy are the best candidates to LR therapy.

Objective:The effect of antiviral therapy for hepatitis B virus (HBV)-related hepatocellular carcinoma (HCC) after radical hepatectomy was assessed. Methods:A total of 478 HBV-HCC patients treated by radical hepatectomy were retrospectively col-lected. Patients in the treatment group (n=141) received postoperative lamivudine therapy (100 mg/d), whereas patients in the control group (n=337) did not. Recurrence-free survival rates, overall survival rates, treatments for recurrent HCC and cause of death were com-pared between the two groups. Propensity score matching was also conducted to reduce confounding bias between the groups. Results:The one-, three-, and five-year recurrence-free survival rates didn't significantly differ between the two groups (P=0.778);however, the one-, three-, and five-year overall survival rates in the treatment group were significantly higher than those in the control group (P=0.002). Similar results were observed in the matched data. Subgroup analysis showed that antiviral treatment conferred a significant sur-vival benefit for Barcelona Clinical Liver Cancer stage A/B patients. Following HCC recurrence, more people in the treatment group were able to choose curative treatments than those in the control group (P=0.031). For cause of death, fewer people in the treatment group died of liver failure than those in the control group (P=0.041). Conclusion:Postoperative antiviral therapy increases chances of receiving curative treatments for recurrent HCC and prevents death because of liver failure, thereby significantly prolonging overall sur-vival, especially in early-or intermedian-stage tumors.

Objective To explore the effects and the molecular mechanism of synergistic hepatocarcinogenesis of HBV and AFB1 in the development of HCC by studying the difference in protein expression profiles in hepatocellular carcinoma exposed to hepatitis B virus and Aflatoxin B1.Method 32 HCC specimens were labeled under four categories based on their biomarkers of HBV and AFB1 exposure:group A:HBV(+)/AFB1 (+),10 cases,group B:HBV(+)/AFB1 (-),10 cases,group C:HBV(-)/AFB1(+),6 cases,groupD:HBV(-)/AFB1(-),6 cases.Normal hepatic tissues from 10 cases of hepatic hemangioma,liver resection and liver transplant donor were chosen as the normal control group.Isobaric Tagging Reagent Quantitative (iTRAQ) Proteomics together with 2DLC MS/MS were applied to analyze the differentially expressed proteins among the 4 groups.Result (1) A total of 117 unique differentially expressed proteins including 53 up-regulated proteins and 64 down-regulated proteins were identified in the four groups.The number of unique differentially expressed proteins,including up-regulated and down-regulated proteins,in group A,group B,group C and group D were 106,97,104 and 74 respectively.(2) Among the 117 differentially expressed proteins,9 proteins were heat shock proteins or chaperones,and they were up regulated in group A,B and C.Besides,15 proteins were detoxification and drug metabolism pathway related proteins,12 of them were down-regulated in group A,and more than half of them were also down-regulated in group B and C.(3) The Reverse Transcriptase PCR result showed the mean expression level of AKR1B10 mRNA in group A was significantly higher than group B,C and D (all P＜0.05,respectively).Group C also showed significantly a higher expression level of AKR1B10 mRNA than group D (P＜0.05).The Western-blot results showed the mean expression level of AKR1B10 protein in group A was significantly higher than group B and D (all P＜0.05,respectively).Conclusions The up-regulated expression of heat shock protein and the down-regulated expression of most protein enzymes related to detoxification and drug metabolism were the common molecular biological events of HCC associated with exposure to HBV and AFB1.This suggested the synergistic hepatocarcinogenesis effects of HBV and AFB1 may be related to dysregulation of protein enzymes related to detoxification and drug metabolism.The overexpression of AKR1B10 may be involved in the AFB1-related hepatocarcinogenesis process.

Objective: To evaluate the targeting activity in the animal model with human hepatoma, the 131I-human antiHBsAg Fab radioimmunoimaging was explored. Methods: Radioimmunoimagings were taken on different intervals after injection of 131 I-human anti-HBsAg Fab to the nude mice and tissue distribution was measured. The human anti-HBsAg Fab was compared with the murine monoclonal antibodies. Results: The experimental group developed tumor positive images after 3 days of radio-labeled monoclonal antibodies injection, and the peak accumulation of radio-activity on the 5th day.Statistics indicated the tumor/liver ratio of the human anti-HBsAg Fab, murine monoclonal antibodies and the control groups were 5.4,4.0 and 0.9 respectively on the 7th day. Conclusions: Our results suggest that the 131 I-human anti-HB-sAg Fab has a considerable targeting activity, and provide an evidence that it can be used as a novel humanized carrer for targeting therapy of hepatoma.

Objective To explore the clinical value of therapeutic alliances of oviduct recanalization and video-laparoscope in the treatment of infertilitas feminis caused by multiple salpingemphraxis. Methods Sixty-seven patients with salpingemphraxis in 127 oviducts complicated with adhesions in fimbriated extremities were enrolled into our study. All the patients underwent separation of adherences in fimbriated extremities and neostomy using a video-laparoscope 2 to 3 days after selective oviduct recanalization. The therapeutic effects were retrospectively reviewed focusing on recanalization rate of proximal three segments, complete recanalization rate, and pregnancy rate and relevant complications during the follow-up period were analyzed. And patients with infertilitas feminis in the follow-up period underwent repeated salpingography to determine whether oviduct was repeatedly obstructed. Results The therapeutic alliance of oviduct recanalization and video-laparoscope were performed successfully in this cohort. Owing to the treatment of oviduct recanalization, recanalization rate of proximal three segments was 97.6% oviducts (124/127). Due to the alliance of oviduct recanalization and video-laparoscope, complete rate of oviduct were 98.4% (122/124). One year after operation, the pregnancy rate, ectopic pregnancy rate, and non pregnancy rate were 58.2% (39/67), 4.5% (3/67), and 37.3% (25/67), respectively. The patients with non pregnancy were composed by repeated oviduct obstruction in 25.4% (17/67) and non obstruction in 11.9% (8/67). Conclusion Therapeutic alliances of oviduct recanalization and video-laparoscope could be an effective method for the treatment of infertilitas feminis caused by multiple salpingemphraxis, and be helpful for the enhancement of pregnancy rate.
