Objective To study the technical method of immunohistochemical staining in pathological tissue.Methods 80 cases of hospitalized patients in our hospital from May 2015 to May 2016 were selected, they were randomly divided into immunohistochemical staining group(immunohistochemistry group, n=40)and biopsy group(n=40)two groups, then the AFP(alpha-Fetoprotein), Glypican-3 positive situation of the the two groups and diagnostic Resultsof patients with different types of disease in the immunohistochemistry group were statistically analyzed.ResultsThe positive rate of AFP(a-Fetoprotein), Glypican-3 of the immunohistochemistry group 92.5%(37/40)was significantly higher than the biopsy group 50.0%(20/40)(P<0.05), Among the 37 cases of positive patients, metastatic tumors 19 cases, hepatocellular carcinoma 9 cases, intrahepatic bile duct carcinoma 7 cases, hemangioma 3 cases, the positive rates were 100.0%, 75.0%, 100.0%, 100.0%, 26 cases died, the mortality rate was 70.3%, of which metastatic tumors 13 cases, hepatocellular carcinoma 6 cases, intrahepatic bile duct carcinoma 5 cases, hemangioma 2 cases, the mortality rates were 72.2%, 66.7%, 71.4%, 66.7%.Conclusion Immunohistochemical staining technic in pathological tissue can promote positive rate, and standard operation procedures can reduce errors, which is worthy of clinical attention.

Objective To study the 2244G→A, 2299 A→G single nucleotide polymorphism (SNP) in the 5' regulatory regions of Toll-like receptor 4 (TLR4) in patients with Gram negative bacteria infection in Shenzhen locality, and to discuss the occurrence, course and prognosis of patients with sepsis. Method Polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) method was used to detect the genotype of TLR4. After the whole blood DNA of patient was extracted and PCR was amplified, the products were 500bp and 599 bp, and were cut by endonuclease Mae Ⅱ and Sph Ⅰ respectively to determine the SNP 2244G→A and 2299 A→G in TLR4. These two kinds of allele frequencies were statistically calculated in all patients. In the meantime, the incidence of septic shock, average hospitalized days, cost and prognosis of all patients were recorded. Statistical analysis was performed with SPSS version 16 software. ANOVA was used for comparison among multiple groups, and t -test and Sighed rank test were used for paired comparison. Results The 2299 and 2244 sites in the 5' regulatory regions of TLR4 gene of patients with Gram negative bacteria infection in Shenzhen locality had various degrees of changes in single nucleotide. Compared with the documented data from Chinese people in general, there was a significant difference in 2299A→G genotype frequency in residents of Shenzhen locality ( P < 0.05). But there were no statistically significant difference in mortality, incidence of septic shock, average days of ICU stay or ICU cost between TLR4 SNP positive and negative groups of patients. Conclusions There is a wide range of genetic variation in the 2299 and 2244 sites in the 5' regulatory regions of TLR4 among citizens of Shenzhen locality with unique distribution. The 2299A→G genotype frequency probably has differences in distribution and population. The pathogenesis and the prognostic factors of sepsis are complicated, whereas the gene polymorphism may be just one of the factors affecting the prognosis of patients with Gram negative bacteria infection.

Secreted frizzled-related protein (SFRP) can inhibit the expression of Wnt signaling pathway through Frizzled protein.The silencing of SFRP gene promoter methylation is associated with the occurrence and metastasis of many cancers such as colorectal cancer,gastric cancer,liver carcinoma,lung cancer and ovarian cancer.Several studies have found that SFRP gene has latent clinical value,which is expected to become the novel target for the gene diagnosis and treatment of cancer.

Objective To compare the diagnostic efficacies of narrow-band imaging (NBI) in distinguishing neoplastic from non-neoplastic colorectal lesions with routine endoscopy and with magnifying endoscopy. Methods Patients with colorectal lesions detected by NBI from September 2008 to February 2010 were enrolled in the study. These lesions were classified by pit pattern and capillary pattern, which was then assessed by reference to histopathology. Results A total of 100 patients with colorectal lesions were enrolled, and the lesions were observed by NBI with ordinary endoscopy (n =64) and NBI with magnifying endoscopy (n =36), respectively, and 7 cases (5 in NBI with ordinary endoscopy and 2 in NBI with magnifying endoscopy) which did not meet the diagnostic criteria were excluded. The overall diagnostic accuracy of NBI endoscopy in distinguishing neoplastic from non-neoplastic colorectal lesions was 91.4% ( 85/93 ), in which NBI with ordinary endoscopy and magnifying endoscopy was 89. 8% (53/59) and 94. 1% (32/34),respectively, with both significantly higher than that of conventional colonoscopy reported in the literature (79. 1% ) (P ＜ 0. 05 ). However, no significant difference was detected between 2 methods ( P ＞ 0. 05 ).Conclusion Similar with NBI magnifying endoscopy, NBI endoscopy without high magnification may also be useful to distinguish neoplastic from non-neoplastic colorectal lesions.

Objective To explore the medium effect of social support in process of attachment styles and coping styles on criminal juveniles and adolescents with mood disorders.Methods The survey used in the research included Experiences of Close Relationships Inventory (ECR),Social Support Revalued Scale(SSRS) and Coping Style Questionnaire(CSQ) conducted by three groups:177 criminal juveniles,80 adolescents with mood disorders and 163 normal teenagers.Results Firstly,there were significant differences in the avoidant attachment,attachment anxiety,objective support,subjective support,utilization of support,solving problem,rationalization,self-accusation and retreat among three groups (F=7.902,8.047,59.009,19.248,5.304,7.596,10.652,6.699,11.009;P＜0.05).Secondly,attachment avoidance had significant negative correlation with both utilization of support and help seeking behaviors in the group of mood disorders (r =-0.470,-0.350; P＜ 0.01).Similarly,avoidant attachment had significant negative correlation with both subjective support and utilization of support respectively (r=-0.232,-0.235 ; P＜0.01) in the group of criminal juveniles.The subjective support had significant positive correlation with solving problem (r=0.272,P＜0.01) and as well as the utilization of support with both solving problem and help seeking behaviors (r=0.258,0.424; P＜ 0.01).Attachment anxiety had significant negative correlation with objective support and had significant positive correlation with self-accusation respectively (r=-0.253,0.300;P＜0.01).Finally,utilization of support as a medium completely effect on the process of avoidant attachment and help seeking behaviors in the group of mood disorder and criminal juveniles.Moreover,subjective support and utilization of support as medium both affected a part in the process of avoidant attachment and solving problem for the group of criminal juveniles.Conclusion First,both adolescents with mood disorders and criminal juveniles have unsafe attachment mode,which are lacked social support and easy to take negative coping styles.Yet,the level of attachment avoidance and subjective support of criminal juveniles was found different compared to teenagers with mood disorder.Second,the attachment styles for both adolescents with mood disorders and criminal juveniles have impact on coping styles by the means of social support,but there were slightly different way.

Objective To investigate the expression of LncRNA LINC00857 in pancreatic cells and the effect of lncRNA LINC00857 down-regulation on proliferation, migration and apoptosis of pancreatic cancer PANC-1 cells and possible mechanism. Methods The lentiviral vector GV112 was constructed and infected PANC-1 cells to obtain experimental group, while the blank plasmid was transfected as a negative control group and the cells without intervention were taken as normal control group. CCK-8 assay, Transwell assay, scratch test, flow cytometry, Western blot were used to detect the effect of LINC00857 down-regulation on cell proliferation, migration, apoptosis, cell cycle and EMT-related proteins.

Background/Aims: Previous studies have shown that diet and physical activity can influence constipation. However, the combined effect of diet and physical activity on constipation remains unclear. Methods: Constipation was defined based on stool consistency and frequency, while overall diet quality was assessed using Healthy Eating Index (HEI)-2015 scores. Participants were categorized into low (metabolic equivalent [MET]-min/wk < 500) and high physical activitygroups (MET-min/wk ≥ 500). The association between diet and constipation across physical activity groups was analyzed using surveylogistic regression and restricted cubic splines. Results: Higher HEI-2015 scores were associated with reduced constipation risk in the high physical activity group when constipation was defined by stool consistency (odds ratio [OR], 0.98; 95% confidence interval [CI], 0.97-0.99). However, in the low physical activity group, increased HEI-2015 scores did not significantly affect constipation risk (OR, 1.01; 95% CI, 0.97-1.05). Similar results were found when constipation was defined based on stool frequency. In the high physical activity group, increased HEI-2015 scores were significantly associated with a reduced constipation risk (OR, 0.96; 95% CI, 0.94-0.98). Conversely, in the low physical activity group, increased HEI-2015 scores did not affect the risk of constipation (OR, 0.96; 95% CI, 0.90-1.03). Conclusions Our findings suggest that a higher HEI-2015 score is negatively associated with constipation among individuals with high physical activity levels but not among those with low physical activity levels. This association was consistent when different definitions of constipation were used. These results highlight the importance of combining healthy diet with regular physical activity to alleviate constipation.

Objective:To compare the efficacy and safety of oral terbinafine versus itraconazole in the treatment of pediatric tinea capitis.Methods:From January 2021 to December 2021, a randomized clinical trial was conducted among 53 children with tinea capitis in Beijing Children′s Hospital. These patients were randomly divided into 2 groups by using a random number table: terbinafine group treated with oral terbinafine at different doses (weight <20 kg, dose: 62.5 mg/d; weight 20 - 40 kg, dose: 125 mg/d; weight >40 kg, dose: 250 mg/d), while itraconazole group treated with oral itraconazole at doses of 3 - 5 mg·kg -1·d -1. Statistical analysis was performed using the SPSS 23.0 software, and enumeration data were compared between groups by using chi-square test or Fisher′s exact test. Results:Totally, 27 patients were treated with oral terbinafine, including 17 with tinea alba and 10 with kerion; 26 were treated with oral itraconazole, including 17 with tinea alba and 9 with kerion. After treatment, 14 (51.85%) patients were cured in the terbinafine group, including 5 with tinea alba and 9 with kerion, while 25 (96.15%) were cured in the itraconazole group, including 16 with tinea alba and 9 with kerion. The response rate was significantly higher in the itraconazole group than in the terbinafine group ( χ2 = 13.37, P < 0.001) . Conclusion:The efficacy of itraconazole was superior to that of terbinafine in the treatment of pediatric tinea alba, but their efficacy was equivalent in the treatment of pediatric kerion.
