OBJECTIVETo establish the method of isolation, purification, and identification of human amniotic mesenchymal stem cells (hAMSCs).
METHODShAMSCs were isolated from human amniotic membrane by trypsin-collagenase digestion, and cultured in Dulbecco's modified Eagle's medium/F12 medium supplemented with 10% fetal bovine serum. Phenotypic characteristics of these cells were analyzed by means of immunocytochemistry and flow cytometry.
RESULTSThe cells successfully isolated from human amniotic membrane expressed representative mesenchymal cell surface markers CD44, CD90, and vimentin, but not CD45.
CONCLUSIONSThis study establishes a potential method for isolation of hAMSCs from human amnion,in vitro culture, and identification. The isolated cells show phenotypic characteristics of mesenchymal stem cells.

OBJECTIVETo observe the effect of the human amniotic membrane (HAM) loaded with human amniotic mesenchymal stem cells (hAMSCs) on the skin wounds of SD rats.
METHODSThe amniotic epithelial cells were removed by trypsin digestion, hAMSCs were loaded onto HAM and then covered on rats' skin defects. The wound healing was observed by HE staining and immunohistochemistry, and the results were compared with the amniotic membrane group and blank control group.
RESULTSThe average wound healing time was (18.3 +/- 0.9) d in the HAM load with hAMSCs group, which was significantly faster than those in the blank control group [(26.4 +/- 0.7) d, P < 0.01] and the amniotic membrane group [(21.5 +/- 1.2) d, P < 0.05]. After 11 d and 14 d, the wound healing rates in the HAM load with hAMSCs group were (81.5 +/- 7.2)% and (94.3 +/- 3.6)%, respectively, which were significantly higher than those in the blank control group [(48.5 +/- 3.2)% and (74.3 +/- 4.3 )%] and the amniotic membrane group [(68.5 +/- 4.5)% and (86.8 +/- 4.8)%] (all P < 0.01). Skin biopsy/HE staining confirmed that the quality of wound healing in the HAM load with hAMSCs group was significantly better than in the amniotic membrane group and the blank control group. Immunohistochemical staining showed that the number of CK19-positive epidermal stem cells in the HAM load with hAMSCs group (48.2 +/- 3.2) was significantly larger than those in the amniotic membrane group (37.7 +/- 3.1) (P < 0.05) and the blank control group (29.6 +/- 2.4) (P < 0.01). Furthermore, the vascular endothelial growth factor expression (64.5 +/- 4.5) in the HAM load with hAMSCs group was also significantly higher than those in the amniotic membrane group (52.6 +/- 3.8) (P < 0.05) and the blank control group (40.7 +/- 3.1) (P < 0.01).
CONCLUSIONHAM loaded with hAMSCs may promote the repair of skin wounds by promoting the regeneration of epidermal stem cells and capillaries.

OBJECTIVETo evaluate the roles of cell adhesion, multidrug resistance and cell proliferation in short-term recurrent cases with superficial bladder cancer, and the prognostic value of the three indexes.
METHODSImmunohistochemical staining for E-cad, P-gp and Ki-67 was performed on the tumors of 100 patients with stage T0-T1 transitional cell carcinoma of the bladder who had been included in a retrospective research by follow-up.
RESULTSE-cad and P-gp expression was positive in 51 (43.2%)and 17 (14.4%) of the tumors, respectively and mean proliferation index (PI) was 22.1%. The decrease in E-cad expression was accompanied with the increasing recurrent episodes (P < 0.05), while increase of P-gp expression and PI were accompanied with the increasing recurrence episodes (P < 0.05). There was significant difference according to E-cad, P-gp positivity and between T(1)G(3) patients and no-T(1)G(3) patients (P < 0.05). There was negative correlation of E-cad expression with P-gp expression and PI.
CONCLUSIONSMinimum adhesion, strong drug resistance and maximum proliferation are the main factors that promote short-term recurrence of superficial bladder cancer and also the inherent reasons for easy recurrence and high malignancy of T(1)G(3) tumors. During this course, the three aspects may interact.

OBJECTIVETo study the incidence and risk factors of campus violence and to provide evidence for preventing campus violence among college students.
METHODS5300 college students in two universities in a province of China were selected to participate in the study and were interviewed with questionnaires. Logistic regression was used for data analysis.
RESULTS(1) In total, 3910 useable questionnaires were gathered to show a response rate of 73.77%. 17.98% of the college students reported they had ever experienced campus violence in the last one year. 29.60% of the male students experienced campus violence so as 7.27% of the female students. The incidence of violence among male students was significantly higher than those of female students (chi2 = 329.89, P = 0.000). (2) Among male students who were victims of campus violence, the incidence rates of threat or blackmail, emotional abuse, physical assault, verbal sexual harassment, sexual assault were 18.03%, 13.97%, 10.77%, 0.85%, 0.48% respectively. Among female students who were victims of campus violence, the incidence rates were 3.64%, 5.84%, 1.38%, 1.33%, 1.13% respectively. The main source of the violence was from their schoolmates. (3) 10.40% of the male students reported they were perpetrators of campus violence in the last year, while 1.47% of the female students reported so. Schoolmates were the main subjects of their aggressive behaviors. (4) Among the college students who were victims of campus violence, logistic regression analysis revealed that smoking, drinking alcohol, frequently getting computer online were important risk factors. The OR values were 1.48, 2.96, 1.66 respectively. Among college students who were perpetrators of campus violence, the OR values were 2.92, 1.88, 2.09 respectively.
CONCLUSIONCampus violence among college students was serious, suggesting that intervention measures should be taken.

The liver injury induced by Polygonum multiflorum Thunb. (PM) was investigated based on idiosyncratic hepatotoxicity model co-treated with lipopolysaccharide (LPS) at a non-hepatotoxic dose. Sprague-Dawley (SD) rats were intragastrically administered with three doses (18.9, 37.8, 75.6 g crude drug per kg body weight) of 50% alcohol extracts of PM alone or co-treated with non-toxic dose of LPS (2.8 mg·kg(-1)) via tail vein injection. The plasma alanine aminotransferase (ALT) and aspartate aminotransferase (AST) activities were assayed and the isolated livers were evaluated for histopathological changes. The dose-toxicity relationships of single treatment of PM or co-treatment of LPS were investigated comparatively to elucidate the idiosyncratic hepatotoxicity of PM. The results showed that no significant alterations of plasma ALT and AST activities were observed in the groups of solo-administration of LPS (2.8 mg·kg(-1), i.v.) or different dosage (18.9, 37.8 and 75.6 g·kg(-1), i.g.) of PM, compared to normal control group (P > 0.05); while significant elevations were observed in the co-administration groups of PM and LPS. Treatment with LPS alone caused slight infiltration of inflammatory cells in portal area but no evident hepatocytes injury. Co-treatment with LPS and PM (75.6 g·kg(-1), i.g.) caused hepatocyte focal necrosis, loss of central vein intima and a large number of inflammatory cell infiltration in portal areas. When further reduce the dosage of PM, significant increases of plasma ALT and AST activities (P < 0.05) were still observed in co-administration groups of LPS and PM (1.08 or 2.16 g·kg(-1)), but not in LPS or PM solo-administration groups. Nevertheless, the co-treatment of low dosage of PM (0.54 g·kg(-1)) with LPS did not induce any alteration of plasma ALT and AST. In conclusion, intragastric administration with 75.6 g·kg(-1) of PM did not induce liver injury in normal rats model; while the 2 folds of clinical equivalent dose of PM (1.08 g·kg(-1)) could result in liver injury in the LPS-based idiosyncratic hepatotoxicity model, which could be used to evaluate the idiosyncratic hepatotoxicity of PM.

Military training is intense, difficult and often dangerous, so all kinds of injuries or diseases frequently occur during training. Most of the previous studies and reviews on military training-related injuries focused on musculoskeletal system, whereas there are no reviews of abdominal injuries and diseases. Although the incidence of military training-related abdominal injuries and diseases is relatively low, the patients’ condition is often critical especially in the presence of abdominal organ injury, leading to multi-organ dysfunction syndrome and even death. This paper elaborates on common types of military training-related abdominal injuries and diseases as well as the prevention and treatment measures, which provides some basis for scientific and reasonable training and improvement of medical security.
