The aging process of human colonic epithelium involves a slow decline in physiological vigor and an increasing susceptibility to age-related diseases, especially, colon cancer, but the molecular mechanisms of the aging and susceptibility of aged colonic epithelium to carcinogenesis is still unclear. Identification of aging related proteins in colonic epithelium will help to reveal the molecular mechanisms of colonic epithelial aging and age-related colonic diseases. Therefore, the total proteins of human normal colonic epithelial tissues from 10 young and 10 old men were separated by two-dimensional gel electrophoresis(2-DE), respectively. PDQuest software was applied to analyze 2-DE images, the differentially expressed protein spots of colonic epithelium between young and old groups were identified by matrix-assisted laser desorption/ionization time of flight mass spectrometry(MALDI-TOF-MS), and the expression levels of partial identified proteins were determined by real-time quantitative PCR and immunohistochemistry. Well-resolved, reproducible 2-DE maps of human colonic epithelial tissues from young and old men were established, 17 aging related proteins were identified by MALDI-TOF-MS, and the differential expression levels of partial identified proteins were confirmed by real-time quantitative PCR and immunohistochemistry. The results indicate that injury of mitochondrial function and decline of antioxidant capability are important reasons for the aging of human colonic epithelium, and four differential proteins (guanine nucleotide-binding protein beta subunit-like protein, stress-70 protein, 40 S ribosomal protein SA and chloride intracellular channel protein1) may be involved in susceptibility of aged colonic epithelium to carcinogenesis.

OBJECTIVETo compare the clinical effects and radiographic outcomes of mini-open trans-spatium intermuscular and percutaneous short-segment pedicle fixation in treating thoracolumbar mono-segmental vertebral fractures without neurological deficits.
METHODSFrom August 2009 and August 2012, 95 patients with thoracolumbar mono-segmental vertebral fractures without neurological deficits were treated with short-segment pedicle fixation through mini-open trans-spatium intermuscular or percutaneous approach. There were 65 males and 30 females, aged from 16 to 60 years old with an average of 42 years. The mini-open trans-spatium intermuscular approach was used in 58 cases (group A) and the percutaneous approach was used in 37 cases (group B). Total incision length, operative time, intraoperative bleeding, fluoroscopy, hospitalization cost were compared between two groups. Visual analog scale (VAS) and radiographic outcomes were compared between two groups.
RESULTSAll patients were followed up from 12 to 36 months with an average of 19.6 months. No complications such as incision infection, internal fixation loosening and breakage were found. In group A, fluoroscopy time was short and hospitalization cost was lower than that of group B (P<0.05). But the total incision length in group B was smaller than that of group A (P<0.05). There was no significant differences in operative time, intraoperative bleeding, postoperative VAS and radiographic outcomes between two groups (P>0.05). Postoperative VAS and radiographic outcomes were improved than that of preoperative (P<0.05).
CONCLUSIONThe mini-open trans-spatium intermuscular and percutaneous short-segment pedicle fixation have similar clinical effects and radiographic outcomes in treating thoracolumbar mono-segmental vertebral fractures without neurological deficits. However, in this study, the mini-open trans-spatium intermuscular approach has a short learning curve and more advantages in hospitalization cost and intraoperative radiation exposure times, and is recommendable.

OBJECTIVETo investigate the correlation of sexual dysfunction with psychological abnormalities by analyzing the sexual function and mental state of the patients with redundant prepuce or phimosis.
METHODSThis study included 216 randomly selected patients with redundant prepuce or phimosis and 85 normal male controls. We conducted investigations among the subjects using a questionnaire on the general data of the patients, Chinese Index of Sexual Function for Premature Ejaculation (CIPE), International Index of Erectile Function (IIEF), and Symptom Checklist 90 (SCL-90). Then we assessed the status of premature ejaculation (PE) and erectile dysfunction (ED), calculated the incidence of psychological abnormalities, such as depression and anxiety, and analyzed the correlation of PE and ED with the mental state of the patients.
RESULTSThe PE and ED patients scored significantly higher than normal controls on SCL-90, somatization, compulsion, depression, anxiety and other factors (P < 0.05). CIPE scores were correlated with the scores on SCL-90, somatization, compulsion, interpersonal sensitivity, depression, anxiety and other factors, while ED-related scores showed no correlation with the scores on SCL-90 and other factors.
CONCLUSIONPatients with redundant prepuce or phimosis have poor mental health, and there is an interaction between PE and the mental state of the patient.

In order to analyze the prognosis and related factors of acute lymphoblastic leukemia (ALL), 53 newly diagnosed ALL patients were enrolled in this study. The therapeutic efficacy and prognosis of 53 cases of ALL were analyzed, the remission, relapse, overall survival and event-free survival were studied, and relation between different factors and prognosis of ALL were investigated by comparison of cases in same stage. The results showed that the complete remission was achieved in 36 out of 53 patients, the total remission rate was 67.9%, the total relapse rate was 37.7%, the median relapse duration was 6 months after remission. Median overall survival (OS) and median event-free survival (EFS) time were 4 and 1 months after remission respectively, OS and EFS rate of 18 month was 35.1% and 14.2%. The patients with different gender had significantly different EFS. Age was an independent risk factor of CR rate. White blood cell count and hemoglobin level of newly diagnosed patients were significantly correlated with OS and EFS. Absolute neutrophil count (ANC) at the end of the induction chemotherapy was an independent related factor of OS, the higher ANC, the lower risk of death. The patients with or without chemotherapy related infection had different relapse rate. The patients with bleeding after chemotherapy had lower OS when compared with those without bleeding. Serum glucose level was a significant negative prognostic factor. It is concluded that there is higher relapse rate, poor prognosis in adult ALL in comparison with children. In order to decrease the relapse rate and prolong the EFS, individual therapeutical regimens and prophylaxis of complicating diseases should be applied to ALL patients.

OBJECTIVETo investigate the association between physical activity (PA) and the incidence of metabolic syndrome (MS) in Chinese adults.
METHODSData on PA and other variables were obtained at the baseline examination of China Multi-center study of Cardiovascular Epidemiology in 1998 and of International Collaborative study of Cardiovascular Disease in Asia(InterASIA) during 2000 - 2001. Follow-up study was conducted in 2007 - 2008. A total of 11 512 Chinese adults aged 35 - 74 years (5563 men and 5949 women) were included in the final data analysis. Information on demographics, PA, smoking and alcohol consumption were obtained and components of MS were examined. Participants were divided into four groups according to quartile of total metabolic equivalent (MET) values per day. In addition, subjects were grouped into the following categories according to occupational PA: inactive, light, moderate and vigorous. Binary logistic model was used to examine the association between PA and the incidence of MS.
RESULTSA total of 2527 cases with MS were documented during an average following up of 8.1 years. The annual incidence rate of MS was 2.71% (2527/93 178.68). After multivariate logistic regression analysis, compared with participants with total PA volume < 32.0 MET×h×d(-1) (annual incidence rate was 3.19% (697/21 830.74)), the RR (95%CI) value of participants with total PA volume during 32.00 - 37.85, 37.86 - 52.29, and ≥ 52.30 MET×h×d(-1) was 1.05(0.92 - 1.19), 0.98(0.86 - 1.12), and 0.68(0.59 - 0.80), respectively (χ(2)trend = 34.23, P < 0.05), with corresponding annual incidence rates of 2.82% (690/24 504.25), 2.73% (661/24 179.36) and 2.11% (479/22 664.33). In addition, compared to inactive occupational PA (annual incidence rate was 2.76% (402/14 588.33)), the corresponding RR (95%CI) value was 0.80 (0.69 - 0.92), 0.70 (0.59 - 0.82), and 0.54 (0.45 - 0.65) (χ(2)trend = 42.34, P < 0.05), and the annual incidence rates were 2.86% (648/22 663.41), 2.40% (455/18 956.14) and 1.89% (344/18 173.86) in participants with light, moderate and vigorous occupational PA, respectively.
CONCLUSIONBoth increased total PA volume and occupational PA intensity are significantly associated with decreased risk of incidence of MS.

Objective To explore the effect of glioma stem cells with high expression of protein tyrosin phosphatase receptor type Z1 (PTPRZ1 )on the phenotypic polarization and phagocytosis of tumor-associated macrophages and its regulatory mechanism.Methods GSCs and non-stem tumor cells (NSTCs) were screened out from human glioblastoma (GBM) specimens using flow cytometry,and the PTPRZ1 expression in paired GSCs and NSTCs were detected.Human peripheral blood mononuclear cells (PBMC)-derived CD14+monocytes were exposed to the conditioned medium from glioma cells or recombinant chemokine C-C motif ligand 20 (CCL20)for TAM polarization.Stable PTPRZ1 knockout GSCs (PTPRZ1-KO GSCs) were constructed using CRISPR/Cas9. TAM phagocytosis to GSCs,NSTCs,PTPRZ1-Control GSCs (PTPRZ1-Ctrl GSCs)and PTPRZ1-KO GSCs and the expression of immunosuppressive phenotype (M2) polarization marker CD163 were examined using flow cytometry.Differentially expressed genes (DEGs ) between paired GSCs and NSTCs were determined using a bulk RNA-sequencing dataset (GSE54791 )from Gene Expression Omnibus (GEO).A gene set informing worse outcome of patients with GBM was generated using The Cancer Genome Atlas (TCGA)-GBM cohort.By intersecting the aforementioned gene set with the gene set that encodes for human membrance proteins,the PTPRZ1 gene is obtained.Gene set enrichment analysis (GSEA)was used for pathway enrichment analysis to compare the differentially regulated pathways between GBMs with high or low PTPRZ1 expression.Bulk RNA sequencing,qRT-PCR and Western blotting were used to identify the DEGs between PTPRZ1-KO GSCs and PTPRZ1-Ctrl GSCs.Results GSCs were more capable of escaping from TAM phagocytosis than NSTCs (P<0.05 )and had specifically up-regulated PTPRZ1 expression.PTPRZ1-KO significantly suppressed GSCs escaping from TAM phagocytosis (P<0.01 ). GBMs with high PTPRZ1 expression showed significant inhibition of pathways mediating phagocytosis (P<0.05).The expression of CCL20 as a M2 TAM polarization chemokine was significantly down-regulated in PTPRZ1-KO GSCs (P<0.05 ).Treatment with recombinant CCL20 up-regulated the expression of CD163 as a M2 TAM marker in TAM.Conclusion PTPRZ1+GSCs mediate M2 TAM polarization and inhibit TAM phagocytosis,which may be related to the up-regulation of CCL20 in PTPRZ1+GSCs.
