Objective To compare the effect of the tissue adhesive Histoacryl and traditional suturing treatment on the cracked wounds on children's craniofacial skin. Methods About 152 children patients with cracked wounds children's craniofacial skin from March 2015 to June 2015 were divided into two groups according to their parents' will. Group A, with 77 patients, was treated by the tissue adhesive Histoacryl and Group B, with 75 patients, was treated by traditional suturing. The two groups were compare in terms of the treatment time and effect. Result The treatment time of Group A was significantly shorter than that of Group B (P<0.001), while there was no significant difference between the two groups in the level of wound healing (P>0.05). Conclusions Compared to the traditional suturing, the tissue adhesive Histoacryl is advantageous, for its easy operation, short treatment time, prominent efficacy and beautiful appearance. Moreover, it can relieve the pain of children during the treatment.

Objective Regenerating genes express mainly in gastrointestinal tissues and the injured regenerating pancreatic tissues,which can promote the regeneration of pancreatic β cells and other tissue cells.In recent years,researches on Reg family mainly involved the gene structure of various subtypes of Reg,and its role in diabetes,gastrointestinal cancer,inflammation,anti-microbial and the related mechanisms.Among the various subtypes of Reg,regenerating geneⅢ(Reg3) plays a particularly crucial role in these diseases.Therefore,Reg3 is a promising target for the treatment of these diseases.Based on the relationships of Reg3 with a variety of diseases,our group devote to the role of Reg3 [human REG3A,and mouse Reg3γ(Reg3g)] in type 1 diabetes,inflammation-linked pancreatic carcinogenesis,and the immunological changes participated in these processes.Hence,this review will summarize serial studies on Reg3 and the feasibility of it as drug targets.

Objective To investigate the mechanisms of inhibitory effect of Erlotinib,an epidermal growth factor(VEGF) receptor inhibitor,on angiogenesis of pancreatic carncer.Methods①In a tube formation assay,Erlotinib(100?mol/L) was applied to the culture media and compared to the serum free media.The expression of vascular endothelial growth factor(VEGF) in BxPC-3 cells treated with Erlo- tinib at different concentrations(5,50,100,200?mol/L) was determined by RT-PCR.②The xeno grafts derived from BxPC 3 cancer cells were inoculated into the BALB/C nude mice.The mice were treated with either Erlotinib(100 mg/kg of Erlotinib oral lavage daily) or saline for four weeks.The vol- ume of the xenografts was measured and the tumor growth rate was calculated.The microvessel density (MVD) of tumor tissue was determined by immunohistochemistry with an antibody against factorⅧ. Results There were less endothelium cells and close hollow tubular structures in grlotinib treated group compared to the control group in the tube formation assay.The mean weight of xenografts in Erlotinib treated group[(0.397?0.550)g] was significantly lower than that in the control group[(1.570?1.060)g] with a inhibitary rate of 74.5%.The expression of VEGF mRNA in Ertotinib treated groups (=50?mol/L) were decreased comparing to the control group.The VEGF expression in xeno- grafts tumor tissues was also markedly down-regulated.The MVI) was significantly decreased in Erlotinib treated group( 1.86?0.43)than that in the control group (5.98?1.27,P

Objective To study the regulatory T cells (Treg-cell) frequencies in patients with childhood acute leukemia and evaluate its clinical application value by investigating the relationship between the increasing numbers of Treg cells and minimal residual disease of leukemia (MRD), Methods Foxp3-FITC/CD25-PE/CD4-PerCP/CD3-APC four-color staining flow cytometry was established to identify Treg cells. Treg cells frequencies both in 10 healthy controls and in 33 patients with newly diagnosed childhood acute leukemia ( B-ALL 17 cases, T-ALL 9 cases, AML 7 cases) were detected. The possibility of the accumulation of Treg cells being the prognostic marker for acute leukemia was evaluated by comparing the results of Treg cells frequency with that of MRD. Results The percentage of Treg cells in CD+4 CD+3 T cells was M = 8. 09% in normal bone marrows, which was significantly different from the results in the bone marrows of newly diagnosed childhood acute leukemia ( M = 12.77% , U = 3.41, P < 0.01 ), but it showed no significantly differences among B-ALL, T-ALL and AML groups. No association was observed between the expression of Treg cells and clinical-biologic characteristics studied. In addition, Treg cells frequency in MRD positive group was significantly different from that in MRD continuously negative group ( M = 14. 74% vs M=11.3%, t =252.5,P<0.05). Conclusions Consistent with results from solid tumor, the study identifies a significantly increased numbers of Treg cells in patients with childhood acute leukemia. The situation of accumulation of Treg cells is closely associated with MRD results during chnical remission. High level of Treg cells may cause poor prognosis and increase the possibility of relapse.

The JC virus is a widely infected human polyomavirus. Recent foreign researches showed that the JC virus infection is correlated with tumors of nervous system and digestive system, while, and study on the relationship between JC virus infection and gynecological tumor is seldom reported. In this study, we first establish the nucleic acid detection methods and procedures for JC virus and its highly homologous BK virus. The JC and BK viruses infection was evaluated by detect the viral DNA in samples including biopsy tissues, serum as well as urine of myoma of uterus (98 cases), cervical cancer (84 cases), endometrial cancer (40 cases) and ovarian tumor (72 cases) patients. The BK viral DNA positive rate was significantly higher in urine samples than that of blood and biopsy samples, and there is no significant difference of the BK viral DNA positive rate among all patient groups. The JC viral DNA positive rate is almost 0 in serum samples and biopsy. tissues, however, viral DNA positive rate is more than 50% in urine samples. In fibroids group, the JC viral DNA positive rate is up to 65. 3% which is significantly higher than that in other patients groups and healthy control. Further gynecological tumor associated viruses detection showed that only human papilloma virus infection is associated with cervical cancer, the herpes simplex virus, EB virus and cytomegalovirus infection is extremely low in our patient groups. No synergistic effect on gynecological tumor caused by viruses co-infection was observed. Our study showed that JC virus infection is highly related to the pathogenesis of uterine fibroids.

Objective To investigate the effect of cold atmospheric plasma (CAP) on the healing of skin ulcers using Balb/c mice. Methods Wounds with a diameter 6 mm were created on each side of the backs of BalB/c mice ( n = 150) using a punch bioptome. The mice were assigned randomly into a control group ( wounds healed naturally), a laser group (wounds treated with a He-Ne laser for 10 min daily) and a CAP group (wounds treated with CAP for 10 min daily). Wound healing was evaluated on postoperative days (PODs) 4, 7, 10 and 14 in terms of percent wound closure. Ten mice per group were sacrificed on each of the evaluation days. Both wounds were removed and a histological examination was conducted. A scoring system was used to evaluate the wounds. The expression of vascular endothelial growth factors (VEGFs) in the wounded tissue was detected by using immunohistochemical methods on POD 7. The results were quantified using an HPIAS-1000 system. Results Compared with the control group, the average percentage of wound healing was significantly greater in the CAP group on PODs 7 and 10. The average scores on the histological examination were significantly higher in the CAP group on PODs 7, 10 and 14. Compared with the other two groups, the expression of VEGF was up-regulated significantly in the CAP group.Conclusions CAP can positively affect the wound healing process. This might be related to the up-regulation of VEGF in the wounded tissues.
