By now,the mutations of C-KIT gene and PDGFRA have been regarded as the most important primary incidences.The latest results have revealed the fact that the abnormal expressions of p53,p16,p21 WAF-1,p27 and E-cadherin(cDH1) which were labeled as anti-oncogenes in most of human tumors,existed in the progression of gastrointestinal stromal tumor.Therefore,we put forward the theory that gene mutaion may lead to the instability of DNA that further promotes mutation of short tandem repeat in anti-oncogene coding region,on basis of which,that finally lead to the malignant progession of gastrointestinal stromal tumor by anti-oncogene mutation.

Cellular schwannoma is a rare benign tumor of the peripheral nerves.The tumor is consist of spindle cells which arranged in interwoven bundles,and lacking the mesh district and palisading structure.The tumor cells are abundant,with coarse chromatin,deeply stained nuclei and in multiforms.So the tumor may easily be misdiagnosed as various types of spindle cell sarcoma.Intraperitoneal cellular schwannoma may also be mistaken as gastrointestinal stromal tumors.In this article,the clinical characteristics,diagnosis and treatment of cellular schwannoma were analyzed based on the clinical data of a patient with cellular schwannoma in the gastric wall misdiagnosed as gastric stromal tumor.

Abstract? AIM: To analysis the relation of severity of rhegmatogenous retinal detachment with the levels of amino acids and vascular endothelial growth factor ( VEGF) in the serum and in subretinal fluid.? METHODS: Forty -eight patients ( 52 eyes ) with rhegmatogenous retinal detachment treated in our hospital were selected.According to the degree of retinal detachment, patients were divided into <1/2 quadrant group, 1/2-3/4 quadrant group and>3/4 quadrant group. Fifty-five healthy objects for physical examination in our hospital were selected as the control group, to compare the differences of amino acids and VEGF levels in the serum.Correlation analysis on VEGF levels and amino acids in the serum and in subretinal fluid among patients with different grades of rhegmatogenous retinal detachment was conducted.? RESULTS: In patients with rhegmatogenous retinal detachment, the tryptophan in serum was 28.59±4.46mg/L, phenylalanine 8.95 ±2.55mg/L, methionine 8.15 ±2.17mg/L, valine 28.62 ±5.29mg/L, histidine 18.96 ±1.85mg/L and VEGF 589.92 ±185.34μg/L, which were higher than those in the control group, and the difference was statistically significant(P<0.05).The levels of phenylalanine was 9.85 ±1.21mg/L, histidine 20.63 ±2.07mg/L and VEGF 718.69 ± 283.34μg/L in the subretinal fluid of>3/4 quadrant group, which were significantly higher than those in the <1/2 quadrant group and 1/2-3/4 quadrant group ( P<0.05). VEGF in the subretinal fluid of VEGF in the rhegmatogenous retinal detachment group were positively correlated with phenylalanine (r=0.542, P<0.001), and histidine (r=0.782, P<0.001).?CONCLUSION: The levels of amino acids and VEGF in the subretinal fluid of patients with rhegmatogenous retinal detachment was higher than those in normals and increased with the severity of retinal detachment.

Objective:To explore the characteristics of prevailing factors and their influence on esophageal cancer in Xinjiang. Meth-ods:Patients diagnosed with esophageal cancer from January 2010 to January 2016 were selected from the Xinjiang Medical Universi-ty First Affiliated Hospital and categorized as the patient group. Patients without cancer admitted to the same period were classified as the control group. Case control study and correlation analysis between esophageal cancer and type 2 diabetes were performed. Re-sults:Type 2 diabetes (≥2 years), as a risk factor, is associated with esophageal cancer. The use of insulin (≥2 years) can increase the risk of esophageal cancer. Smoking, drinking, hyperlipidemia, body mass index≥24, and esophageal diverticulum esophageal cancer are also risk factors. Conclusion:The risk factors for esophageal cancer are prevalent among patients with type 2 diabetes patients. In-sulin use is also correlated with the occurrence of esophageal cancer. Further studies must be performed to develop secondary preven-tion for diabetic patients susceptible to esophageal cancer in high-risk subgroups.

Objective:To study the effects of Tongxinluo,a traditional Chinese medicine,on the proliferation of peripheral blood-derived endothelial progenitor cells(EPCs)in vitro.Methods:The Tongxinluo solution was prepared through ultrasonication according to the pervious literature.The mononuclear cells(MNCs)were isolated from the peripheral blood with Ficoll by density gradient centrifugation.MNCs were suspended in Medium 199 containing 20% fetal blood serum(FBS)and vascular endothelial growth factor(VEGF).After cultured for 7 d,the attached cells were characterized by Di-LDL uptaking and FITC-lectin binding by laser confocal microscope,and further identified through detection of CD34 and CD133 expression by flow cytometry.Then the cultured EPCs were incubated with Tongxinluo at a series of concentrations(0,50,100,200,500, 750,1000?g/ml)for different durations(0,6,12,24 and 36 h).The cell morphology was observed and cell proliferation was determined by MTT assay.Results:Incubation with different concentrations of Tongxinluo increased the proliferative ability of EPCs.Tongxinluo at 500?g/ml had the most prominent effect on proliferation and the effect increased as time went by and reached peak at 36 h(growth rate 54.18%,P

Objective To test the levels of vascular endothelial growth factor (VEGF) in bronchoalveolar lavage fluid (BALF) during acute lung injury (ALI)/acute respiratory distress syndome (ARDS) after the interference with anticoagulation and fibrinolytic in an attempt to find a possible treatment plan for ALI/ARDS.Methods Oleic acid-induced ALI models were used in this study.A total of 96 rats were randomly assigned oleic acid group,salvianolate group,urokinase group,and saline group according to the random number table,with 24 animals per group.In oleic acid group,oleic acid (0.2 ml/kg,caudally) was administered alone.In addition to the oleic acid,the rats in salvianolate and urokinase groups received caudal injection with 10 ml/kg of 0.06％ salvianolate and 5,000 U/kg of urokinase respectively.In saline group,saline solution with an equal volume of oleic acid was caudally administered alone.Effect of the early use of salvianolate and urokinase on levels of VEGF in BALF was measured.Clinically,patients with ALI/ARDS composing survivor and death groups were enrolled and assessed by acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ) score and multiple organ dysfunction syndrome (MODS) score.Besides,healthy population was included as the controls to comparatively analyze the levels of VEGF in BALF in ALI/ARDS group.Results Of the rat models of ALI,early use of salvianolate or urokinase was associated with elevated level of VEGF in BALF (P ＜0.05),which subsequently attenuated the lung injury.In the clinical research,it was found that the level of VEGF in BALF in ALI/ARDS group was much lower than that in control group [(45.9 ± 5.7) pg/ml vs (60.6 ± 4.5) pg/ml] (P ＜ 0.01).The level of VEGF in BALF was negatively correlated with APACHE Ⅱor MODS scores (r =-0.542,-0.659,P ＜ 0.01).Moreover,patients in death group appeared lower VEGF level in BALF than those in survivor group(t =2.68,P ＜ 0.05).Conclusion VEGF level in BALF can be taken as an indicator of patient condition and outcome.Early use of anticoagulation or thrombolytic drugs may play a positive role on patients with ALI/ARDS.

UNLABELLEDOBJECTIVE To investigate the effect of Nepsilon-(carboxymethyl) lysine albumin (CMLs), a primary advanced glycation end products (AGEPs) isoform in diabetic body, on the function and angiogenesis of adipose tissue-derived stem cells (ADSCs) and the protective effect of Danhong Injection (DH). METHODS Human ADSCs were cultured and separated from human subcutaneous fatty tissue using enzymatic digestion and centrifugation. The morphology was observed using optical microscope and differentiation capacities assessed. Cells were exposed to 5 different interventions respectively for 24 h, i.e., PBS, 60 1 microg/mL BSA, 60 microg/mL CML-BSA, 100 microL/mL DH, and 60 micro./mL CML-BSA +100 microL/mL DH. Their effect on the proliferation, migration, apoptosis, and secretion were observed using WST-1 assay, Transwell assay, Annexin V-FITC/PI flow meter test reagent kit, human VEGF reagent kit, ELISA reagent kit, respectively. The effect on ADSCs angiogenesis was observed by in vitro angiogenesis test.

RESULTSCompared with the BSA group, the capacities of proliferation and migration could be significantly inhibited by CML-BSA, the apoptosis promoted, the secretion of VEGF reduced, and the angiogenesis of ADSCs weakened (P < 0.05). Compared with the blank control group, 100 microL/mL DH could significantly promote the proliferation and migration capacities of ADSCs, inhibit apoptosis of ADSCs, increase the secretion of VEGF, and improve the angiogenesis of ADSCs (P < 0.05). Compared with the CML-BSA group, the inhibition of CML-BSA on the proliferation and migration capacities of ADSCs could be significantly reversed, the promotion of CML-BSA on the apoptosis of ADSCs improved, the secretion of VEGF increased, and the angiogenesis of ADSCs elevated (P < 0.05).

CONCLUSIONclusion CMLs could significantly inhibit the proliferation and migration capacities of ADSCs, promote their apoptosis, and inhibit their angiogeneses, which could be improved by DH.

Objective Diabetic mice models were established.Hearts were separated from the body,reperfused after ischemia,and disposed of with the extraneous calcitonin gene-ralated peptide (CGRP),to prove if the CGRP had protective effect on the early-staged diabetic mice with cardiac ischemia.Method ICR mice were injected with Streptozocins intraperitoneally to establish diabetic model.The model mice and the normal mice were randomly divided into 4 groups:two diabetic groups,two control groups.Hearts of the experimental mice were taken out from the chest cavity alive,and hanged on the Langendorff steadily for 30min.Western blot and radioimmunoassay techniques were used to test expression of Vanilloid receptor(VR1) and CGRP in myocardic tissue;Madlab system was used to test the cardiac function,which including left ventricular end-diastolic pressure (LVEDP),left ventricular developed pressure (LVDP),heart rate (HR),and coronary artery flow (CF),in the process of ischemic reperfusion,And ELISA assay kit was used to measure the concentration of the lactate dehydrogenase (LDH) in perfusion fluid collected from the heart.Result Expressions of VR1 and CGRP in diabetic hearts were significantly lower than those in normal ones 2 weeks later(P＜0.01).By comparing with normal hearts,diabetic hearts had higher LVEDP and CF (P＜0.05),and lower LVDP and HR(P＜0.05).However,release of LDH were lower than normal ones (P＜0.05).Predisposition of normal and diabetic hearts with CGRP can improve the cardiac function after ischemie injury.And the beneficial effect was more profound in early-staged diabetic hearts than in normal ones.Conclusion The diabetes disease(DM) can impair the expression of CGRP in myocardiac tissue.The extraneous CGRP may exert more potent protective effect on cardiac function in the early-staged diabetic heart.

OBJECTIVE To investigate whether the KCNN4 gene and KPTN gene contribute to a Chinese non-syndromic hearing loss pedigree linked to DFNA4 with positional candidate approach. METHODS The complete coding region of the two genes were amplified with polymerase chain reaction (PCR), and bidirectional sequencing of the PCR products was subsequently applied in the 36 family members to identify the possible mutations or polymorphisms in the candidate genes. RESULTS Sequence analysis of coding regions and splice sites of the two candidate genes in 36 members including 12 hearing-impaired individuals in family Z002 failed to demonstrate any deafness-causing mutations of KCNN4 gene. There was one heterozygous mutation identified in exon10 coding sequence (942C/T) of KPTN gene, which did not result in amino acid change (P302P) as a repoerted synonymous SNP site (rs2293424). This SNP site did not cosegregate with the phenotype of family Z002. CONCLUSION Our study excluded the two candidates, KCNN4 and KPTN , as the causative genes involved in this Chinese DFNA4 pedigree.
