Objective To explore the reason of colon cancer with appendicitis and reduce the rate of misdiagnosis. Methods We car-ried out analysis retrospectively to analyze 1 094 hospitalized patients with colon cancer in the First Affiliated Hospital of Harbin Medical Uni-versity from January 2006 to March 2013. Results Among 1 094 colon cancer patients,31 patients who firstly diagnosed with acute appendi-citis received appendectomy,1 patient with appendiceal abscess received non-surgical treatment. Among 31 patients with acute appendicitis,6 patients were found to be with ileocecal tumors during surgeries;24 patients were diagnosed with colon cancer within one year;incision of 1 patient did not heal, with continuous drainage of brown liquid;the appendicitis of 1 patient who received non-surgical treatment was recur-rent. Conclusion As lack of typical symptoms,colon cancer is prone to misdiagnose and diagnose incorrectly when the cancer co-exists with appendicitis and symptoms of appendicitis were showed firstly. Therefore,clinicians should be vigilant for patients with appendicitis. In order to induce the rate of misdiagnosis,it is essential that requesting disease history carefully,timely and relevant inspection and appropriate ex-ploratory surgery for the patients with appendicitis.

Gastrointestinal stromal tumors are the common mesenchymal tumors of the gastrointestinal tract. The constitutive activation of KIT is one of the earlies ttransforming events in GISTs and occurs mainly through activating mutations in the kit gene. PDGFRa is associated with the pathogenesis of GISTs too. The main mutative site of KIT gene are exon11, exon9, exon13 and exon17 and those of PDGFRA are exon18, exon12 and exon14.The clinical parameter and the response to imatinib of GISTs are associated with the site and type of gene mutation. Imatinib mesylate is a small-molecule inhibitor that selectively inhibit the tyrosine kinase and the clinical use of it is one milestone of the targeted therapy of GISTs. We review the gene mutation and targeted therapy development of gastrointestinal stromal tumors in this article.

ObjectiveTo investigate the association of HLA-Cw and -DRB1 alleles with psoriasis vulgaris,and to provide a clue to the study into the etiology of psoriasis.MethodsVenous blood samples were obtained from 81 patients with psoriasis vulgaris collected during 2006-2011 at the Department of Dermatology,First Affiliated Hospital of Inner Mongolia Medical College,as well as 100 age- and gender-matched healthy controls.Both the patients and controls are unrelated Mongolia in Inner Mongolia.PCR with sequence-specific primers(PCR-SSP) technique was used to genotype the HLA-Cw and DRB1 loci.ResultsThe patients with psoriasis vulgaris showed a significantly higher frequency of HLA-Cw*06(0.438 vs.0.175,Pc ＜ 0.01) and DRB1*07(0.241 vs.0.110,Pc ＜ 0.012),but a lower frequency of HLA-Cw*04(0.031 vs.0.150,Pc ＜ 0.01 ) and DRB1*04 (0.093 vs.0.235,Pc ＜ 0.01 ) than the healthy controls did.Increased frequencies of HLA-Cw*06 and DRB1*07 alleles were observed in patients with an onset before 40 years of age and those without a family history,together with a decreased frequency of HLA-Cw*04 and DRB1*04 alleles,compared with the healthy controls(Pc ＜ 0.05).The frequency of HLA-Cw*06 allele was significantly higher in patients with a positive family history and patients with an onset of no younger than 40 years of age than in the healthy controls (both Pc ＜ 0.05).ConclusionsHLA-Cw*06 and -DRB1*07 alleles may be susceptibility determinants to psoriasis vulgaris,while HLA-Cw*04 and -DRB1*04 alleles may be protective factors against psoriasis vulgaris,in Mongolia from Inner Mongolia.HLA-DRB1*07 allele may be a susceptibility gene for psoriasis,while HLA-Cw*04 and -DRB1*04 alleles may be protective factors against psoriasis,in patients with an onset before 40 years of age.

The aim of this study was to observe whether necroptosis is involved in the process of cardiac hypertrophy induced by pressure overload. SD rats underwent transverse abdominal aortic constriction (TAC) operation for establishing cardiac hypertrophy model. The structure and function of the left ventricle of rats were evaluated via echocardiography, left ventricular mass index, the expression of markers of cardiac hypertrophy and histological detection. Real-time PCR and Western blot were used to measure the gene and protein expression of receptor interacting protein kinase 1 and 3 (RIPK1 and RIPK3, the necroptosis markers) respectively. Four weeks after TAC operation, rat model for cardiac hypertrophy was established. The experimental data showed that the gene and protein expressions of RIPK1 and RIPK3 in the rat heart hypertrophic tissues after TAC for 4 weeks were increased significantly compared with those in the sham group. HE staining showed cardiomyocytes injury and hypertrophy in the hearts of TAC rat models. By transmission electron microscope, we observed that mitochondria of cardiomyocytes were damaged seriously in the TAC models. Treatment with losartan used, the selective antagonist of angiotensin II type I receptor could improve the cardiac function of TAC rats. Moreover, losartan treatment decreased the expression of RIPK1 and RIPK3 in heart tissues of TAC rats. The results suggest that necroptosis occurrs in the process of cardiac hypertrophy with pressure overload, and losartan could alleviate the cardiac hypertrophy and inhibit necroptosis.

The aim of this study is to construct specific shRNA expressing plasmids, and to observe their effects on H9c2 cardiomyocytes injury induced by hypoxia/reoxygenation (H/R). RIPK1 and RIPK3 are the key kinases mediating the process of necroptosis. Using recombinant DNA technology, we inserted the synthetic shRNA into pSUPER vector to construct RIPK1-shRNA or RIPK3-shRNA plasmid respectively. We transfected H9c2 cardiomyocytes with the two shRNA plasmids respectively, before we treated them with H/R stimulation. Then, we measured the relevant genes and proteins by real-time PCR and Western blot. Meanwhile,we detected the markers of necroptosis and cardiomyocytes injury. The results showed that inhibition of ripk1 or ripk3 gene expression by its specific shRNA might protect the cardiomyocytes injury induced by H/R stimulation.

Objective To investigate intestinal bacteria genera distribution between normal weight and overweight/obesity school-age children in Yili region of Xinjiang.Methods Selecting eligible 150 fecal samples from school-age children (aged from 7 to 13 years old),all samples were divided into normal weight group and overweight/obesity group according to the body mass index (BMI),and each group contained 75 samples.Fecal samples were collected and DNA was extracted,then 6 types of intestinal bacteria genera were detected by the quantitative real-time polymerase chain reaction.Results The distribution of age,gender,ethnicity and hip circumference between 2 groups had no statistically significance (all P ＞ 0.05),except that of BMI and waist circumference (t ＝ 20.740,8.533,all P ＜ 0.01).The concentration of Lactobacillus,Clostridium and Enterococcus were significantly higher in the obese/overweight children (t =9.735,9.681,26.070,all P ＜ 0.01),whereas no significant differences were found in the concentration of Escherichia,Bifidobacterium and Bacteroides between 2 groups.According to the stratified analysis of ethnicity,gender and age,there was no significant difference among Han,Kazakh and Uyghur children.While stratified by gender,Bifidobactcrium was significantly lower in girls than that of boys (t =4.931,P ＜ 0.05).The distribution of the 6 types of intestinal bacteria genera was no statistically significant among different ethnicity,gender and age groups.Conclusions The intestinal bacteria genera number distribution in different ethnicity,gender and age groups makes no sense.The 16SrRNA type number of the Lactobacillus,Clostridium and Enterococcus may be associated with childhood obesity.

Objective To analyze the levels and clinical significances of IL-18,Caspase-3 and nerve tissue-specific protein S-100B at different disease extent and different stages of infants with hypoxicischemic encephalopathy (HIE).Methods This study was clinical experimental studies.Sixty-seven infants with HIE (23 cases of mild HIE,23 cases of moderate HIE,21 cases of severe HIE) from February 2008 to June 2009 in Hebei Children's Hospital were enrolled.The levels of IL-18,Caspase-3 and S-100B protein in all samples were measured at acute phase (1 d,3 d) and recovery phase (7 d) by ELISA method.Twenty healthy full-term neonates were selected as the normal control group.Multi-factor analysis of variance and Pearson correlation test was used for statistical analysis.Results The levels of the three indicators in the moderate and severe group were higher than the normal control group.In the moderate group,IL-18 levels were(132.15 ± 9.87),(150.31 ± 15.04) and (87.91 ± 9.93) ng/L,Caspase-3 levels were (5.79 ±0.64),(7.36 ± 1.57)and (3.79 ±0.61) μg/L,S-100B levels were(6.82 ±0.61),(9.62 ± 1.29) and (10.76 ± 1.64) μg/L.In the severe group,IL-18 levels were (160.23 ± 16.03),(189.86 ± 18.32) and (107.35 ± 13.02) ng/L;Caspase-3 levels were (6.86 ± 1.02),(9.54 ± 1.43) and (5.25 ± 0.71) μg/L;S-100B levels were(8.90 ± 0.32),(12.54 ± 0.89)and(13.53 ± 0.75) μg/L.In the normal control group,IL-18 levels were (71.08 ± 11.52),(72.53 ± 11.05) and (71.93 ± 11.30) ng/L; Caspase-3 levels were (2.84 ± 0.52),(2.98 ± 0.53) and (2.87 ± 0.52) μg/L; S-100B levels were (1.50 ± 0.25),(1.62 ±0.30)and(1.53 ±0.29) μg/L IL-18 levels,Caspase-3 levels and S-100B levels in severe group were higher than the moderate group and the mild group were higher than the mild group.IL-18 levels were (73.46 ± 4.77),(77.59 ± 4.02) and (72.87 ± 6.92) ng/L ; Caspase-3 levels were (3.13 ± 0.31),(3.63±0.40) and (3.26 ±0.45) μg/L;S-100B levels were(3.68 ±0.40),(5.851 ±0.63) and(6.95 ± 0.58) μg/L in the mild group.S-100B levels in the mild group were higher than that in the normal control group.The IL-18 and Caspase-3 levels were risen in the third day to the first day in the acute phase of the moderate group and severe group,decreased in the recovery phase.Serum S-100B protein levels in the acute and recovery phase increased gradually,and there was no correlation between the three indicators (r-=0.321,0.14,0.48,P=0.438,0.974,0.911 respectively).Conclusions IL-18,Caspase-3 and S-100Bwere involved in the pathophysiological process of HIE.The levels were closely related to the severity and disease progression of HIE,the severer of the illness,and the higher of the levels.Dynamic monitoring the changes of the three indicators may contribute to an early diagnosis,condition monitoring and prognosis of HIE.

Twenty patients with prostate cancer and 20 patients with benign prostate hyperplasia (BPH) in the transitional zone underwent magnetic resonance imaging (MRI) /magnetic resonance spectroscopic imaging ( MRSI ) examinations. The choline + creatine/citrate (CC/Ci) ratio and the choline/creatine (Cho/Cr) ratio were evaluated in each voxel with cancer or BPH confirmed by pathological results.Discriminant analysis was used to determine the power of the two ratios in differentiation between cancer and BPH. The CC/Ci ratio and Cho/Cr ratio for cancer voxels were significantly higher than those in the voxels with BPH in the transitional zone (CC/Ci: 2.26 ± 1.35 vs. 0.81 ±0.22, t =5.17, P ＜0. 01, Cho/Cr:4. 12 ± 1.65 vs. 1.25 ±0. 35, P＜0. 01 ). As for the discriminant function with the CC/Cr ratio and the Cho/Cr ratio, the specificity, sensitivity, and accuracy were 99%, 86%, 93% respectively for the differentiation between cancer and BPH.

Objective To investigate the clinical value of MR elastography in the diagnosis of prostate cancer at 3.0 T, and to assess the elasticity and viscosity of prostate cancer and benign prostatic diseases. Methods Eight patients (63±7years old) with 12 foci of prostate cancer and 10 patients(59±3 years old) with 14 foci of prostatitis in the peripheral zone were evaluated by MR elastography.MR elastography was performed by transmitting low-frequency longitudinal mechanical waves of 100 Hz into prostate with a transducer placed above the pubic bones. The phase images were reconstructed to acquire viscoelastic mapping. T test was used to compare the mean elasticity and viscosity of prostate cancer and prostatitis. The correlation of elasticity and Gleason scores between prostate cancer and prostatitis were also retrospectively analyzed with Pearson Correlation. Results The mean elasticity and viscosity were significantly higher in prostate cancer[(6.55±0.47)kPa,(6.56±0.99)Pa·s,respectively]than in prostatitis[(1.99±0.66)kPa,(2.13±0.21)Pa·s,respectively],and the difference was statistically significant (t=19.392,16. 372; P ＜ 0.01). In 8 patients with prostate cancer, the Gleason scores were 5 (2 cases), 6 (3 cases), 7 (2 cases) and 8 (1 case), respectively. The mean elasticity for the cases with different Gleason scores was 5.83,6.02,7.45 and 8.05 kPa, respectively. There was a positive correlation between Gleason scores and elasticity of the prostate cancer( r = 0. 913, P ＜ 0. 01 ) in this study.Conclusion MR elastography can be used to visualize the difference in stiffness between prostate cancer and benign prostatic disease, it is a new imaging method with great potential in grading of prostate cancer.
