AIM: To investigate the causes of small intestinal bleed- ing as well as its diagnosis and therapeutic approaches. METHODS: A retrospective analysis was conducted ac- cording to the clinical records of 76 patients with small intestinal bleeding admitted to our hospital in the past 5 years. RESULTS: In these patients, tumor was the most fre- quent cause of small intestinal bleeding (37/76), fol- lowed by Meckel’s diverticulum (21/76), angiopathy (15/76) and ectopic pancreas (3/76). Of the 76 patients, 21 were diagnosed by digital subtraction angiography, 13 by barium and air double contrast X-ray examination of the small intestine, 11 by 99mTc-sestamibi scintigraphy of the abdominal cavity, 6 by enteroscopy of the small intestine, 21 by laparoscopic laparotomy, and 4 by ex- ploratory laparotomy. Although all the patients received surgical treatment, most of them (68/76) received part enterectomy covering the diseased segment and entero- anastomosis. The follow-up time ranged from 1 year to 5 years. No case had recurrent alimentary tract bleeding or other complications. CONCLUSION: Tumor is the major cause of small in- testinal bleeding followed by Meckel’s diverticulum and angiopathy. The main approaches to definite diagnosis of small intestinal bleeding include digital subtraction an- giography, 99mTc-sestamibi scintigraphy of the abdominal cavity, barium and air double contrast X-ray examina- tion of the small intestine, laparoscopic laparotomy or exploratory laparotomy. Part enterectomy covering the diseased segment and enteroanastomosis are the most effective treatment modalities for small intestinal bleed- ing. 展开更多

AIM: To research the etiology, portal vein thrombosis and other features of Budd-Chiari syndrome (BCS) patients prospectively. METHODS: A total of 75 patients (40 female, 35 male) who were diagnosed between January 2002 and July 2004 as having BCS were studied prospectively. Findings from on physical examination, ultrasonography, duplex ultrasonography and venography were analyzed. Hemogram and blood chemistry were studied at the time of diagnosis and on each hospital visit. Bone marrow examination and immune phenotyping were performed by a hematologist when necessary. Protein C, S, antithrombin Ⅲ, activated protein C resistance, and anticardiolipin antibodies, antinuclear antibodies, and anti ds-DNA were studied twice. The presence of ascite, esophageal varices, and portal thrombosis were evaluated at admission and on every visit. RESULTS: At least one etiological factor was determined in 54 (72%) of the patients. The etiology could not be defined in 21 (28%) patients. One etiological factor was found in 39, 2 factors in 14 and 3 factors in 1 patient. The most common cause was the web (16%), the second was Hydatid disease (11%), the third was Behcet’s disease (9%). Portal vein thrombosis was present in 11 patients and at least one etiology was identified in 9 of them (82%). CONCLUSION: Behcet’s disease and hydatid disease are more prominent etiological factors in Turkey than in other countries. Patients with web have an excellent response to treatment without signs of portal veinthrombosis while patients having thrombofilic factors more than one are prone to develop portal vein thrombosis with worse clinical outcome. 展开更多

AIM:To compare the incidence of early portal or splenic vein thrombosis(PSVT) in patients treated with irregular and regular anticoagulantion after splenectomy with gastroesophageal devascularization.METHODS:We retrospectively analyzed 301 patients who underwent splenectomy with gastroesophageal devascularization for portal hypertension due to cirrhosis between April 2004 and July 2010.Patients were categorized into group A with irregular anticoagulation and group B with regular anticoagulation,respectively.Group A(153 patients) received anticoagulant monotherapy for an undesignated time period or with aspirin or warfarin without low-molecular-weight heparin(LMWH) irregularly.Group B(148 patients) received subcutaneous injection of LMWH routinely within the first 5 d after surgery,followed by oral warfarin and aspirin for one month regularly.The target prothrombin time/international normalized ratio(PT/INR) was 1.25-1.50.Platelet and PT/INR were monitored.Color Doppler imaging was performed to monitor PSVT as well as the effectiveness of thrombolytic therapy.RESULTS:The patients' data were collected and analyzed retrospectively.Among the patients,94 developed early postoperative mural PSVT,including 63 patients in group A(63/153,41.17%) and 31 patients in group B(31/148,20.94%).There were 50(32.67%) patients in group A and 27(18.24%) in group B with mural PSVT in the main trunk of portal vein.After the administration of thrombolytic,anticoagulant and antiaggregation therapy,complete or partial thrombus dissolution achieved in 50(79.37%) in group A and 26(83.87%) in group B.CONCLUSION:Regular anticoagulation therapy can reduce the incidence of PSVT in patients who undergo splenectomy with gastroesophageal devascularization,and regular anticoagulant therapy is safer and more effective than irregular anticoagulant therapy.Early and timely thrombolytic therapy is imperative and feasible for the prevention of PSVT. 展开更多

AIM:To review percutaneous transhepatic portal venoplasty and stenting(PTPVS)for portal vein anastomotic stenosis(PVAS)after liver transplantation (LT). METHODS:From April 2004 to June 2008,16 of 18 consecutive patients(11 male and 5 female;aged 17-66 years,mean age 40.4 years)underwent PTPVS for PVAS.PVAS occurred 2-10 mo after LT(mean 5.0 mo). Three asymptomatic patients were detected on routine screening color Doppler ultrasonography(CDUS). Fifteen patients who also had typical clinical signs of portal hypertension(PHT)were identified by contrastenhanced computerized tomography(CT)or magnetic resonance imaging.All procedures were performed under local anesthesia.If there was a PVAS<75%, the portal pressure was measured.Portal venoplasty was performed with an undersized balloon and slowly inflated.All stents were deployed immediately following the predilation.Follow-ups,including clinical course, stenosis recurrence and stent patency which were evaluated by CDUS and CT,were performed. RESULTS:Technical success was achieved in all patients.No procedure-related complications occurred. Liver function was normalized gradually and the symptoms of PHT also improved following PTPVS.In 2 of 3 asymptomatic patients,portal venoplasty and stenting were not performed because of pressure gradients<5 mmHg.They were observed with periodic CDUS or CT.PTPVS was performed in 16 patients.In 2 patients,the mean pressure gradients decreased from 15.5 mmHg to 3.0 mmHg.In the remaining 14 patients,a pressure gradient was not obtained because of>75%stenosis and typical clinical signs of PHT.In a 51-year-old woman,who suffered from massive ascites and severe bilateral lower limb edema after secondary LT,PVAS complicated hepatic vein stenosis and inferior vena cava(IVC)stenosis. Before PTPVS,a self-expandable and a balloonexpandable metallic stent were deployed in the IVC and right hepatic vein respectively.The ascites and edema resolved gradually after treatment.The portosystemic collateral vessels resulting from PHT were visualized in 14 patients.Gastroesophageal varices became invisible on poststenting portography in 9 patients.In a 28-yearold man with hepatic encephalopathy,a pre-existing meso-caval shunt was detected due to visualization of IVC on portography.After stenting,contrast agents flowed mainly into IVC via the shunt and little flowed into the portal vein.A covered stent was deployed into the superior mesenteric vein to occlude the shunt. Portal hepatopetal flow was restored and the IVC became invisible.The patient recovered from hepatic encephalopathy.A balloon-expandable Palmaz stent was deployed into hepatic artery for anastomotic stenosis before PTPVS.Percutaneous transhepatic internal-external biliary drainage was performed in 2 patients with obstructive jaundice.Portal venous patency was maintained for 3.3-56.6 mo(mean 33.0 mo) and all patients remained asymptomatic.CONCLUSION:With technical refinements,early detection and prompt treatment of complications,and advances in immunotherapy,excellent results can be achieved in LT. 展开更多

AIM: To investigate the effect of angiopoietin-1 (Ang-1) on biological behaviors in vitro and tumorigenesis and angiogenesis in vitro of human gastric cancer cells. METHODS: Human full-length Ang-1 gene was cloned from human placental tissues by RT-PCR method. Recombinant human Ang-1 antisense eukaryotic expression vector was constructed by directional cloning, and transfected by lipofectin method into human gastric cancer line SGC7901 with high Ang-1 expression level. Inhibition efficiency was confirmed by semi- quantitive PCR and Western blot method. Cell growth curve and cell cycle were observed with MTT assays and flow cytometry, respectively. Nude mice tumorigenicity test was employed to compare in vitro tumorigenesis of cells with Ang-1 suppression. Microvessel density (MVD) of implanted tumor tissues was analyzed by immunohistochemistry for factor VIII staining. RESULTS: Full-length Ang-1 gene was successfully cloned and stable transfectants were established, namely 7Ang1- for antisense, and 7901P for empty vector transfected. 7Ang1- cells showed down-regulated Ang-1 expression, while its in vitro proliferation and cell cycle distribution were not significantly changed. In contrast, xenograft of 7Ang1- cells in nude mice had lower volume and weight than those of 7901P after 30 days' implantation (P〈 0.01, 293.00:1±95.54 mg vs. 624.00±77.78 mg) accompanied with less vessel formation with MVD 6.00±1.73 compared to 7901P group 8.44±1.33 (P〈 0.01). CONCLUSION: Ang-1 may play an important role in tumorigenesis and angiogenesis of gastric cancer, and targeting its expression may be beneficial for the therapy of gastric cancer. 展开更多

Some patients with ascites due to liver cirrhosis become no longer responsive to diuretics. Once other causes of ascites such as portal vein thrombosis, malignancy or infection and non-compliance with medications and low sodium diet have been excluded, the diagnosis of refractory ascites can be made based on strict criteria. Patients with refractory ascites have very poor prognosis and therefore referral for consideration for liver transplantation should be initiated. Search for reversible components of the underlying liver pathology should be undertaken and targeted therapy, when available, should be considered. Currently, serial large volume paracentesis (LVP) and transjugular intrahepatic portasystemic stent-shunt (TIPS) are the two mainstay treatment options for refractory ascites. Other treatment options are available but not widely used either because they carry high morlJidity and mortality (most surgical options) rates, or are new interventions that have shown promise but still need further evaluation. In this comprehensive review, we describe the evaluation and management of patients with refractory ascites from the prospective of the practicing physician. 展开更多

MYC is an oncogene involved in cell cycle regulation, cell growth arrest, cell adhesion, metabolism, ribosome biogenesis, protein synthesis, and mitochondrial function. It has been described as a key element of several carcinogenesis processes in humans. Many studies have shown an association between MYC deregulation and gastric cancer. MYC deregulation is also seen in gastric preneoplastic lesions and thus it may have a role in early gastric carcinogenesis. Several studies have suggested that amplification is the main mechanism of MYC deregulation in gastric cancer. In the present review, we focus on the deregulation of the MYC oncogene in gastric adenocarcinoma carcinogenesis, including its association with Helicobacterpylori (Hpylon] and clinical applications. 展开更多

Design: Retrospective and observational case series. Methods: We reviewed 41 patients (41 eyes) suffering exposure of orbital implants from Jan. 2000 to June 2006. The study group patients with mild exposure received com-bined treatment with bFGF and antibiotic drops, and while the control group patients with mild exposure were treated with anti-biotic drops only. The study group patients with moderate and severe exposure received combined treatment with bFGF and antibiotic drops, and after 2 months they were subjected to amniotic membrane transplantation, while the control group patients with moderate and severe exposure underwent amniotic membrane transplantation after using antibiotic drops. Observation of the growth of conjunctival epithelium and comparison of the healing rate of the two groups. Results: The healing rates of the mild, moderate and severe exposure study group were 100% and 92.3%. The healing rates of the mild, moderate and severe exposure control group were 55.6% and 66.7% respectively. The difference of the healing rates of the mild exposure study group and the control group was significant (P=0.033). And the difference of the healing rates of the moderate and severe exposure study group and the control group was not significant (P=0.167). Conclusion: bFGF may promote obviously the healing of orbital implant exposure, particularly it can be the first choice for the treatment of mild degree exposure. For the moderate and severe cases, it can be administered before surgical repair to enhance neovascularization and will tend to increase the success rate of surgical repair. 展开更多

AIM: To summarize our methods and experience with interventional treatment for symptomatic acute-sub-acute portal vein and superior mesenteric vein throm-bosis (PV-SMV) thrombosis. METHODS: Forty-six patients (30 males, 16 females, aged 17-68 years) with symptomatic acute-subacute portal and superior mesenteric vein thrombosis were ac-curately diagnosed with Doppler ultrasound scans, com-puted tomography and magnetic resonance imaging. They were treated with interventional therapy, including direct thrombolysis (26 cases through a transjugular intrahepatic portosystemic shunt; 6 through percutane-ous transhepatic portal vein cannulation) and indirect thrombolysis (10 through the femoral artery to superior mesenteric artery catheterization; 4 through the radial artery to superior mesenteric artery catheterization). RESULTS: The blood reperfusion of PV-SMV was achieved completely or partially in 34 patients 3-13 d after thrombolysis. In 11 patients there was no PV-SMV blood reperfusion but the number of collateral vessels increased signif icantly. Symptoms in these 45 patients were improved dramatically without severe operationalcomplications. In 1 patient, the thrombi did not respond to the interventional treatment and resulted in intestinal necrosis, which required surgical treatment. In 3 patients with interventional treatment, thrombi reformed 1, 3 and 4 mo after treatment. In these 3 patients, indirect PV-SMV thrombolysis was performed again and was successful. CONCLUSION: Interventional treatment, including direct or indirect PV-SMV thrombolysis, is a safe and effective method for patients with symptomatic acutesubacute PV-SMV thrombosis. 展开更多

Treatment of gastrointestinal bleeding in patients with angiodysplasias and Osler’s disease (hereditary hemorrhagic teleangiectasia) is clinically challenging. Frequently, vascular malformations occur as multiple disseminated lesions, making local treatment an unfavorable choice or impossible. After local therapy, lesions often recur at other sites of the intestine. However, as there are few therapeutic alternatives, repeated endoscopic coagulations or surgical resections are still performed to prevent recurrent bleeding. Hormonal therapy has been employed for more than 50 years but has recently been shown to be ineffective. Therefore, new therapeutic strategies are required. Understanding of the pathophysiology of angiogenesis and vascular malformations has recently substantially increased. Currently, multiple inhibitors of angiogenesis are under development for treatment of malignant diseases. Experimental and clinical data suggest that antiangiogenic substances, which were originally developed for treatment of malignant diseases, may also represent long-awaited specif ic drugs for the treatment of vascular malformations. However, antiangiogenics display significantly different actions and side-effects. Although antiangiogenics like thalidomide seem to inhibit gastrointestinal bleeding, other substances like bevacizumab can cause mucosal bleeding. Therefore differential and cautious evaluation of this therapeutic strategy is necessary. 展开更多

To study the inhibitory effect of Huqi San (Qi- protecting powder) on rat prehepatocarcinoma induced by diethylinitrosamine (DEN) by analyzing the mutational activation of c-fos proto-oncogene and over-expression of c-jun and c-myc oncogenes. METHODS: A Solt-Farber two-step test model of prehepatocarcinoma was induced in rats by DEN and 2-acetylaminofluorene (AAF) to investigate the modifying effects of Huqi San on the expression of c-jun, c-fos and c-myc in DEN-mediated hepatocarcinogenesis. Huqi San was made of eight medicinal herbs containing glycoprival granules, in which each milliliter contains 0.38 g crude drugs. T-glutamy-transpeptidase-isoenzyme (T-GTase) was determined with histochemical methods. Level of 8-hydroxydeoxyguanosine (OHdG) formed in liver and c-jun, c-fos and c-myc proto-oncogenes were detected by immunohistochemical methods. RESULTS: The level of 8-OHdG, a mark of oxidative DNA damage, was significantly decreased in the liver of rats with prehepatocarcinoma induced by DEN who received 8 g/kg body weight or 4 g/kg body weight Huqi San before (1 wk) and after DEN exposure (4 wk). Huqi San- treated rats showed a significant decrease in number of T-GT positive foci (P 〈 0.001, prevention group: 4.96-0.72 vs 29.46-2.17; large dose therapeutic group: 7.53-0.88 vs 29.46-2.17). On the other hand, significant changes in expression of c-jun, c-fos and c-myc were found in Huqi San-treated rats. CONCLUSION: Activation of c-jun, c-fos and c-myc plays a crucial role in the pathogenesis of liver cancer.Huqi San can inhibit the over-expression of c-jun, c-fos and c-myc oncogenes and liver preneolastic lesions induced by DEN. 展开更多

Flexibility of the CSIR-RCS, induction stirring with simultaneous air cooling process, in combination with high pressure die casting is successfully demonstrated by semi-solid rheocasting of plates performed on commercial 2024, 6082 and 7075 wrought aluminum alloys. Tensile properties were measured for the above mentioned rheocast wrought aluminum alloys in the T6 condition. The results showed that tensile properties were close to or even in some cases exceeded the minimum specifications. The yield strength and elongation of rheocast 2024-T6 exceeded the minimum requirements of the wrought alloy in the T6 condition but the ultimate tensile strength achieved only 90% of the specification because the Mg content of the starting alloy was below the commercial alloy specification. The strengths of rheocast 6082-T6 exceeded all of the wrought alloy T6 strength targets but the elongation only managed 36% of the required minimum due to porosity, caused by incipient melting during solution heat treatment, and the presence of fine intermetallie needles in the eutectic. The yield strength of rheocast 7075 exceeded the required one and the ultimate tensile strength also managed 97% of the specification; while the elongation only reached 46% of the minimum requirement also due to incipient melting porosity caused during the solution heat treatment process. 展开更多

AIM:To investigate the antiangiogenic effects of endostatin on colonic carcinoma cell line implanted in nude mice and its mechanism. METHODS:Nude mice underwent subcutaneous injection with LS-174t colonic carcinoma cell line to generate carcinoma and were randomly separated into two groups.Mice received injection of vehicle or endostatin every day for two weeks. After the tumor was harvested,the tumor volumes were determined,and the expressions of CD34,VEGF and FIk-1 were examined by immunohistochemical method. RESULTS:Tumor volume was significantly inhibited in the endostatin group(84.17%)and tumor weight was significantly inhibited in the endostatin group(0.197±0.049) compared to the control group(1.198±0.105)(F=22.56, P=0.001),microvessel density(MVD)was significantly decreased in the treated group(31.857±3.515)compared to the control group(100.143±4.290)(F=151.62,P<0.001). Furthermore,the expression of FIk-1 was significantly inhibited in the treated group(34.29%) ompared to the control group(8.57%)(X^2=13.745,P=0.001).However no significant decrease was observed in the expression of vascular endothelial growth factor(VEGF)between these two groups(X^2=0.119,P=0.730). CONCLUSION:Endostatin can inhibit tumor growth and angiogenesis by blocking Vegf/FIk-1 pathway.This experiment provides the theory basis for developing a new anti-carcinoma drug through studying the properties of anti-angiogenesis inhibitors. 展开更多

In order to discuss the role of preoperative chemo- therapy for colorectal liver metastases, which is used frequently before hepatic resection, even in patients with resectable disease at presentation, we herein report the development of two complications, partial portal vein thrombosis and hepatic steatosis with Iobular inflammation, during the course of preoperative chemotherapy with FOLFIRI plus bevacizumab for colorectal liver metastases, which recognition led to timely discontinuation of chemotherapy as well as a change in the surgical strategy to resect the tumors and the damaged liver through advanced techniques. We conclude that duration of treatment and drug doses and combinations may impact the development of chemotherapy-induced liver injury. Surgeons and medical oncologists must work together to devise safe, rational, and oncologically appropriate treatments for patients with multiple colorectal liver metastases, and to improve the understanding of the pathogenesis of chemotherapyinduced liver injury. 展开更多

This group included 120 males and 53 females. The pathologic lesions composed of localized complete occlusion of inferior vena cava (IVC) (78), IVC stenosis (49), IVC membrane with a hole (37), membrane of hepatic vein (HV) (3), IVC thrombosis (4), IVC membrane with thrombosis (2) and IVC lesion with occlusion of HV (32). Treatment methods included that I: Percutaneous transinferior vena cava angioplasty (PTA) (76); II: IVC PTA with stent (59); III: Percutaneous transhepatic vein recanalization (3); IV: IVC thrombolysis through a catheter (4); V; Combined transcardiac and trans-femoral venous membranotomy and balloon dilation (22); VI: V and stent (17); VII; Stenting during radical surgery (3); VIII: Additional operation after intervention (23).Results. The immediate technique success rate for intervention was 90.1%, for the semi-intervention was 100%. The IVC pressure was reduced from 3 to 29 cmH20. Complications occurred in 8 cases. The death rate was 2.9%. A follow-up study showed the recurrence rates were 14.5% in IVC PTA group, 1.7% in IVC PTA with stent, 18.2% in combined technique without stent and no recurrence was found in other groups.Conclusion. The PTA is the first choice for localized lesions. When elastic recoil occurs, immediate stenting is suggested. The semi-interventional approach is advised for PTA failure and more complicated cases. For those with both IVC lesion and occlusion of HV, the additional operation is needed after IVC intervention. 展开更多

Objective:To evaluate the probability and efficacy of endostatin-vascular endothelial growth inhibitor (VEGI) recombinant adenoviruses combined with dexamethasone on suppressing heterolamellar corneal transplantation rejection. Methods: Heterolamellar corneal transplantation models were established in 64 New Zealand rabbits, which were randomized into 4 groups of 16 rabbits each. After the transplantation, all the 64 right eyes were injected subconjunctively with 0.2 ml saline (saline group), 0. 1 ml AdCA13-hENDO-VEGI151 plus 0. 1 ml saline (AdCA13-hENDO-VEGI151 group), 0. 1 ml Dexamethasone (DXM) plus 0.1 ml saline (DXM group), 0. 1 ml AdCA13-hENDO-VEGI151 plus 0. 1 ml DXM (AdCA13-hENDO-VEGI151 combined with DXM group) with one time each 3 days for 10 times. Graft survival and ocular surface were observed for 6 weeks. The fusion protein expression was detected by immunohistochemistry 6 weeks after transplantation. Results: Both the CNV index, rejection index and the xenograft rejection rate in the AdCA13-hENDO-VEGI151 combined with DXM group were statistically lower than those in other groups. AdCA13-hENDO-VEGI151 combined with DXM group: 1. 375 0±0. 500 0, 2. 750 0 ±1. 843 9 and 6.25% respectively 6 week after keratoplasty; Saline group: 3. 437 5±0. 512 3, 8. 812 5± 1. 108 7, 100. 00%; AdCA13-hENDO-VEGI151 group: 2. 312 5±0. 478 7, 5. 625 0±0. 957 4, 62.50%; DXM group: 3. 000 0±0. 816 5, 5. 562 5±1. 315 0, 56.25% (P〈0.01). Immunohistochemical staining showed the fusion protein expressed mainly in corneal epithelium. Conclusion: The fusion protein expressed by the recombinant adenovirus has significant effect on inhibiting neovascularization after heterolamellar corneal transplantation. The topical application of AdCA13-hENDO-VEGI151 combined with DXM suppressed effectively the postoperative xenograft rejection rate of heterolamellar corneal transplantation. 展开更多
