Current and future therapies for inherited cholestatic liver diseases

Familial intrahepatic cholestasis(FIC) comprises a group of rare cholestatic liver diseases associated with canalicular transport defects resulting predominantly from mutations in ATP8B1, ABCB11 and ABCB4. Phe-notypes range from benign recurrent intrahepatic cholestasis(BRIC), associated with recurrent cholestatic attacks, to progressive FIC(PFIC). Patients often suffer from severe pruritus and eventually progressive cholestasis results in liver failure. Currently, first-line treatment includes ursodeoxycholic acid in patients with ABCB4 deficiency(PFIC3) and partial biliary diversion in patients with ATP8B1 or ABCB11 deficiency(PFIC1 and PFIC2). When treatment fails, liver transplantation is needed which is associated with complications like rejection, post-transplant hepatic steatosis and recurrence of disease. Therefore, the need for more and better therapies for this group of chronic diseases remains. Here, we discuss new symptomatic treatment options like total biliary diversion, pharmacological diversion of bile acids and hepatocyte transplantation. Furthermore, we focus on emerging mutation-targeted therapeutic strategies, providing an outlook for future personalized treatment for inherited cholestatic liver diseases.

Melena:A rare complication of duodenal metastases from primary carcinoma of the lung

Small bowel metastases from primary carcinoma of the lung are very uncommon and occur usually in patients with terminal stage disease. These metastases are usually asymptomatic, but may present as perforation, obstruction, malabsorption, or hemorrhage. Hemorrhage as a first presentation of small bowel metastases is extremely rare and is related to very poor patient survival. We describe a case of a 61- year old patient with primary adenocarcinoma of the lung, presenting with melena as the first manifestation of small bowel metastasis. Both primary tumor and metastatic lesions were diagnosed almost simultaneously. Upper gastrointestinal endoscopy performed with a colonoscope revealed active bleeding from a metastatic tumor involving the duodenum and the proximal jejunum. Histological examination and immunohistochemical staining of the biopsy specimen strongly supported the diagnosis of metastatic lung adenocarcinoma, suggesting that small bowel metastases from primary carcinoma of the lung occur usually in patients with terminal disease and rarely produce symptoms. Gastrointestinal bleeding from metastatic small intestinal lesions should be included in the differential diagnosis of gastrointestinal blood loss in a patient with a known bronchogenic tumor.

Serological Diagnosis of Liver Metastasis in Patients with Breast Cancer

Objective To diagnose and explore the serological diagnostic factors for liver metastasis in patients with breast cancer before symptoms occur. Methods A total of 430 female in-patients with breast cancer of stages 0 to IIIC who came to Tianjin Medical University Cancer Institute and Hospital from January 2003 to January 2004 were studied and followed up until May 2011. Serum levels of biochemical markers for tumor and liver were measured at the time of diagnosis. Results Liver metastasis was more likely to occur in patients with stage Ill cancer or c-erbB-2-positive expression. Alanine aminotransferase, aspartate aminotransferase, ~/-glutamyltransferase （GGT）, alkaline phosphatase, lactate dehvdrogenase （LDH）, and carbohydrate antigen 1153 （CA153） levels were significantly higher in patients with liver metastasis than those without liver metastasis. Diagnostic indices of LDH, GGT, and CA153 were 174 U/L, 32 U/L, and 26.48 Dg/L, respectively. The areas under the curves of LDH, GGT, and CEA were 0.795, 0.784, and 0.661, respectively, and sensitivities of parallel tests for LDH and CA153 and for GGT and CA153 were 88.6% and 85.7 %, respectively. The specificity of serial tests for both pairs of enzymes was 97.7%. Conclusions Tile sensitivity and specificity of combined tumor and biochemical markers could be used as indicators during screening for breast-liver metastasis.

Heterotopic pancreas in the gastrointestinal tract

Heterotopic pancreas is defined as pancreatic tissue found outside the usual anatomical location of the pancreas. It is often an incidental finding and can be found at different sites in the gastrointestinal tract. It may become clinically evident when complicated by pathological changes such as inflammation, bleeding, obstruction, and malignant transformation. In this report, a 60-year-old man with carcinoid syndrome caused by heterotopic pancreatic tissue in the duodenum is described, along with a 62-year-old man with abdominal pain caused by heterotopic pancreatic tissue in the gastric antrum. The difficulty of making an accurate diagnosis is highlighted. The patients remain healthy and symptom-free after follow-up of 1 year. Frozen sections may help in deciding the extent of resection intraoperatively. Although heterotopic pancreas is rare, it should be considered in the differential diagnosis of gastrointestinal stromal tumor.

Malrotation causing duodenal chronic obstruction in an adult

Congenital duodenal obstruction is rare in adulthood. An unusual presentation of this condition has led to difficult preoperative diagnosis.We present a case of proximal jejunal obstruction by a congenital band in an adult and review the literature.

Noninvasive Parameters and hepatic fibrosis scores in children with nonalcoholic fatty liver disease

AIM:To evaluate the noninvasive parameters and hepatic fibrosis scores in obese children with nonalcoholic fatty liver disease(NAFLD).METHODS:A total of 77 children diagnosed with NAFLD via liver biopsy were included and divided into 2 subgroups according to the histopathologic staging of hepatic fibrosis:mild(stage 0-1)vs significant fibrosis(stage 2-4).Clinical and laboratory parameters were evaluated in each patient.The aspartate aminotransferase(AST)/alanine aminotransferase(ALT)ratio,AST/platelet ratio index(APRI),PGA index,Forns index,FIB-4,NAFLD fibrosis score,and pediatric NAFLD fibrosis index(PNFI)were calculated.RESULTS:No clinical or biochemical parameter exhibited a significant difference between patients with mild and significant fibrosis.Among noninvasive hepatic fibrosis scores,only APRI and FIB4 revealed a significant difference between patients with mild and significant fibrosis(APRI:0.67±0.54 vs 0.78±0.38,P=0.032 and FIB4:0.24±0.12 vs 0.31±0.21,P=0.010).The area under the receiving operating characteristic curve of FIB4 was 0.81,followed by Forns index(0.73),APRI(0.70),NAFLD fibrosis score(0.58),AST/ALT ratio(0.53),PGA score(0.45),and PNFI(0.41).CONCLUSION:APRI and FIB4 might be useful noninvasive hepatic fibrosis scores for predicting hepatic fibrosis in children with NAFLD.

Long-term survival of a case with multiple liver metastases from duodenal gastrointestinal stromal tumor drastically reduced by the treatment with imatinib and hepatectomy

Constitutive activation of KIT receptor tyrosine kinase is a critical factor in the pathogenesis of gastrointestinal stromal tumors （GISTs）. But there is little information on whether combination of imatinib mesylate （IM） and surgical treatment can prolong survival in the cases with unresectable multiple liver metastases. We report a case of postoperative recurrence of GIST treated by the tyrosine kinase inhibitor IN and surgical treatment. The initial complete response （CR） to treatment continued for 18 mo, but single liver metastasis showed regrowth in the left hepatic lobe during IN treatment. After partial resection of the recurrent tumor, postoperative course was uneventful and the patient has survived without recurrence for 24 too. Currently, imatinib is the first- line therapy for non-resectable GISTs, but a single agent therapy often leads to tumor resistance. Even if tolerance to imatinib occurs, a combination of imatinib and surgical treatment can prolong survival in some cases as reported here. However, further studies on a large number of cases of recurrent GIST are necessary to evaluate the effectiveness of IN treatment combined with surgery.

Analysis and Discussion of Fiber Motion in the Spinning Triangle of Ring Spinning

In order to analyze the effect of the spinning triangle on yarn structure,a shape model of the spinning triangle is established.The fiber motion in the spinning triangle can be divided into three stages,and the relationship between yarn structure and fiber duration as well as the force acting on the fibers in the three stages is analyzed.The fiber elongation in different location of the spinning triangle is variational.The difference is that the elongation of fiber in the middle spinning triangle is bigger than that in the edge of it and the difference will be amplified with the increase of spinning triangle width,which has an effect on the characteristic of yarns structure.Research results for further study on compact yarn structure and improving spinning frame structure provide theory basis.

Duodenal biopsy may be avoided when high transglutaminase antibody titers are present

AIM:To evaluate the predictive value of tissue transglutaminase (tTG) antibodies for villous atrophy in adult and pediatric populations to determine if duodenal biopsy can be avoided.METHODS: A total of 324 patients with celiac disease (CD; 97 children and 227 adults) were recruited prospectively at two tertiary centers. Human IgA class anti-tTG antibody measurement and upper gastrointestinal endoscopy were performed at diagnosis. A second biopsy was performed in 40 asymptomatic adults on a gluten-free diet (GFD) and with normal tTG levels.RESULTS: Adults showed less severe histopathology (26% vs 63%, P<0.0001) and lower tTG antibody titers than children. Levels of tTG antibody correlated with Marsh type in both populations (r=0.661, P<0.0001). Multiple logistic regression revealed that only tTG antibody was an independent predictor for Marsh type 3 lesions, but clinical presentation type and age were not. A cut-off point of 30 U tTG antibody yielded the highest area under the receiver operating characteristic curve (0.854). Based on the predictive value of this cut-off point, up to 95% of children and 53% of adults would be correctly diagnosed without biopsy. Despite GFDs and decreased tTG antibody levels, 25% of the adults did not recover from villous atrophy during the second year after diagnosis.CONCLUSION: Strongly positive tTG antibody titers might be sufficient for CD diagnosis in children. However, duodenal biopsy cannot be avoided in adults because disease presentation and monitoring are different.

NF-κB and ERK-signaling pathways contribute to the gene expression induced by cag PAI-positive-Helicobacter pylori infection

AIM： To elucidate the sequential gene expression profile in AGS cells co-cultured with wild-type Helicobacter pylori （H pylon） as a model of Hpylori-infected gastric epithelium, and to further examine the contribution of cag-pathogenicity islands （cagPAI）-coding type IV secretion system and the two pathways, nuclear factor kappa B （NF-κB） and extracellular signal-regulated kinases （ERK） on wild-type Hpylori-induced gene expression. METHODS： Gene expression profiles induced by Hpylori were evaluated in AGS gastric epithelial cells using cDNA microarray, which were present in the 4600 independent clones picked up from the human gastric tissue. We also analyzed the contribution of NF-κB and ERK signaling on H pylori-induced gene expression by using inhibitors of specific signal pathways. The isogenic mutant with disrupted cagE （△cagE） was used to elucidate the role of cagPAI-encoding type IV secretion system in the gene expression profile. RESULTS： According to the expression profile, the genes were classified into four clusters. Among them, the clusters characterized by continuous upregulation were most conspicuous, and it contained many signal transducer activity-associated genes. The role of cagPAI on cultured cells was also investigated using isogenic mutant cagE, which carries non-functional cagPAI. Then the upregulation of more than 80% of the induced genes （476/566） was found to depend on cagPAI. Signal transducer pathway through NF-κB or ERK are the major pathways which are known to be activated by cagPAI-positive H pylori. The role of these pathways in the whole signal activation by cagPAI-positive H pyloriwas analyzed. The specific inhibitors against NF-κB or ERK pathway blocked the activation of gene expression in 65% （367/566） or 76% （429/566） of the genes whose activation appealed to depend on cagPAI. CONCLUSION： These results suggest that more than half of the genes induced by cayPAI-positive H pylori depend on NF-κB and ERK signaling activation, and these pathways may play a role in the gene expression induced by hostbacterial interaction which may associate with H pylorirelated gastro-duodenal diseases.

Command and Control Cities in Global Space-economy Before and after 2008 Geo-economic Transition

The global economic downturn caused primarily by the US sub-prime mortgage crisis in 2007 engendered revenue loss of the multinational corporations. Existing studies have yet to depict the detrimental impacts on city＇s command and control functions induced by the sub-prime mortgage crisis together with its residual wave of global economic recession on the global spatial economy. Recent and previous studies have produced an ＇instant history＇ of the global spatial economy before the global economic downturn undermines the global economy in late 2008. How- ever, the waxes and wanes of major cities＇ command and control functions on the global economic arena before and after the outbreak of financial crisis and its associated geo-economic transitions are still poorly understood. This paper attempts to contribute a new set of customized data to update and fill in the gap in the literature with the investigation of the command and control functions of cities arotmd the world from 2005 to 2009. Particular attentions are paid to the time-space relationship of the geo-economic transition that can capture the recent historical images of the com- mand and control situation of different cities in the world.

Zinc Finger Protein-activating Transcription Factor Up-regulates Vascular Endothelial Growth Factor-A Expression in Vitro

Objective To construct the zinc finger protein-activating transcription factor (ZFP-ATF) plasmid and evaluate its efficacy in inducing vascular endothelial growth factor (VEGF) expression in EY.HY926 endothelial cells. Methods Firstly, we constructed the ZFP-ATF plasmid, then testified the quantity of VEGF protein in EY.HY926 endothelial cells after transfected with ZFP-ATP plasmid by Western blot, finally, we used the RT-PCR to testify whether the ZFP-ATF can stimulate expression of VEGF splice variants. Results The ZFP-ATF DNA sequences were located the multiclone sites of PVAX1 vector between the site of BamH Ⅰ and Xhol. Western blot result showed VEGF expression in EY.HY926 endothelial cells transfected with ZFP-ATF plasmid was significantly higher than that in cells transfected with VEGF165 (19.95±3.95 vs. 12.15±1.55 μg/μL, P<0.01). RT-PCR result showed VEGF-A mRNA expression level induced by ZFP-ATF was high than that induced by VEGF165. Conclusion ZFP-ATF can up-regulate the VEGF-A expression in comparison with VEGF165, which might have beneficial effects in angiogenesis process.

Pancreas duodenal homeobox-1 expression and significance in pancreatic cancer

AIM： To study the correlations of Pancreas duodenal homeobox-1 with pancreatic cancer characteristics, including pathological grading, TNM grading, tumor metastasis and tumor cell proliferation. METHODS： Reverse transcriptase-polymerase chain reaction （RT-PCR） was used to detect PDX-1 mRNA expression in pancreatic cancer tissue and normal pancreatic tissue. The expression of PDX-1 protein was measured by Western blot and immunohistochemistry. Immunohistochemistry was also used to detect proliferative cell nuclear antigen （PCNA）. Correlations of PDX-1 with pancreatic cancer characteristics, including pathological grading, TNM grading, tumor metastasis and tumor cell proliferation, were analyzed by using χ^2 test. RESULTS： Immunohistochemistry showed that 41.1% of pancreatic cancers were positive for PDX-1 expression, but normal pancreatic tissue except islets showed no staining for PDX-1. In consistent with the result of imunohistochemistry, Western blot showed that 37.5% of pancreatic cancers were positive for PDX-1. RT-PCR showed that PDX-1 expression was significantly higher in pancreatic cancer tissues than normal pancreatic tissues （2^-3.56±0.35 vs 2^-8.76±0.14, p 〈 0.01）. Lymph node metastasis （P 〈 0.01）, TNM grading （P 〈 0.05）, pathological grading （P 〈 0.05） and tumor cell proliferation （P 〈 0.01） were significantly correlated with PDX-1 expression levels. CONCLUSION： PDX-1 is re-expressed in pancreatic cancer, and PDX-l-positive pancreatic cancer cells show more malignant potential compared to PDX-l-negative cells. Therefore, PDX-l-positive cells may be tumor stemcells and PDX-1 may act as alternate surface marker of pancreatic cancer stem cells.

Evidence for a sequential transfer of iron amongst ferritin, transferrin and transferrin receptor during duodenal absorption of iron in rat and human

AIM: To elucidate the sequential transfer of iron amongst ferritin, transferrin and transferrin receptor under various iron status conditions. METHODS: Incorporation of 59Fe into mucosal and luminal proteins was carried out in control WKY rats. The sequential transfer of iron amongst ferritin, transferrin and transferrin receptor was carried out in iron deficient, control and iron overloaded rats. The duodenal proteins were subjected to immunoprecipitation and quantitation by specific ELISA and in situ localization by microautoradiography and immunohistochemistry in tandem duodenal sections. Human duodenal biopsy (n = 36) collected from subjects with differing iron status were also stained for these proteins. RESULTS: Ferritin was identified as the major protein that incorporated iron in a time-dependent manner in the duodenal mucosa. The concentration of mucosal ferritin was significantly higher in the iron excess group compared to control, iron deficient groups (731.5 ± 191.96 vs 308.3 ± 123.36, 731.5 ± 191.96 vs 256.0 ± 1.19, P < 0.005), while that of luminal transferrin which was significantly higher than the mucosal did not differ among the groups (10.9 ± 7.6 vs 0.87 ± 0.79, 11.1 ± 10.3 vs 0.80 ± 1.20, 6.8 ± 4.7 vs 0.61 ± 0.63, P < 0.001). In situ grading of proteins and iron, and their superimposition, suggested the occurrence of a sequential transfer of iron. This was demonstrated to occur through the initial binding of iron to luminal transferrin then to absorptive cell surface transferrin receptors. The staining intensity of these proteins variedaccording to the iron nutrition in humans, with intense staining of transferrin receptor observed in iron deficient subjects. CONCLUSION: It is concluded that the intestine takes up iron through a sequential transfer involving interaction of luminal transferrin, transferrin-transferrin receptor and ferritin.

Laparoscopic repair of hiatal hernia with mesenterioaxial volvulus of the stomach

Although mesenterioaxial gastric volvulus is an uncommon entity characterized by rotation at the transverse axis of the stomach, laparoscopic repair procedures have still been controversial. We reported a case of mesenterioaxial intrathoracic gastric volvulus, which was successfully treated with laparoscopic repair of the diaphragmatic hiatal defect using a polytetrafluoroethylene mesh associated with Toupet fundoplication. A 70-year-old Japanese woman was admitted to our hospital because of sudden onset of upper abdominal pain. An upper gastrointestinal series revealed an incarcerated intrathoracic mesenterioaxial volvulus of the distal portion of the stomach and the duodenum. The complete laparoscopic approach was used to repair the volvulus. The laparoscopic procedures involved the repair of the hiatal hernia using polytetrafluoroethylene mesh and Toupet fundoplication. This case highlights the feasibility and effectiveness of the laparoscopic procedure, and laparoscopic repair of the hiatal defect using a polytetrafluoroethylene mesh associated with Toupet fundoplication may be useful for preventing postoperative recurrence of hiatal her-nia, volvulus, and gastroesophageal reflux.

The expression of Elf-1 and Ki-67 and their correlations in non-small-cell lung cancer

Objective: Elf-1 is a member of the proto-oncogenes Ets-related transcription factor family and over-expressed in many human tumors, Ki-67 is an important nuclear antigen associated with cell proliferation. This study investigated the expression of Elf-1 and Ki-67 in non-small-cell lung cancer(NSCLC) and studied their correlation with the clinicopathological features. Methods: Tissue microarray from 64 cases lung cancer tissue and 10 cases normal lung tissue was constructed, immunohistochemical method was used to evaluate the protein expressions of Elf-1 and Ki-67, correlations of the expression of Elf-1 and Ki-67 to clinicopathological features of NSCLC were analyzed. Results: Expression of Elf-1 and Ki-67 in NSCLC tissues were significantly higher than in normal lung tissues(P < 0.05), the positive rate of Elf-1 and Ki-67 was 73.44% and 64.06% in NSCLC group, Overexpression of Elf-1 in NSCLC was significantly related to histopathological grading, different clinical staging and the intensity of ELF-1 expression was significantly higher in the group with lymph node metastasis than that without(P < 0.05). Overexpression of Ki-67 was also closely related to tumor differentiation, clinical stages and lymph node metastasis(P < 0.05). In addition positive correlation was found between the expressive intensity of Elf-1 and Ki-67(τ = 0.295, P = 0.018). Conclusion: The high expression and positive correlation of Elf-1 and Ki-67 in NSCLC suggest that they probably play a role in onset and progression of lung cancer, united detecting their expression could be used as an valuable molecular biological index for predicting the malignant behavior and early diagnosis of NSCLC.
