Gallibacterium anatis,a member of the Pasteurellaceae family,constitutes a part of the normal micro-flora of the upper respiratory tract and the lower genital tract in chickens.However,increasing evidence indicate that G.anatis is also associated with a wide range of pathological changes,particularly in the reproductive organs,which leads to decreased egg production,lowered animal welfare and increased mortality.As a recently defined opportunistic pathogen limited focus has been placed on the pathogenesis and putative virulence factors permitting G.anatis to cause disease.One of the most studied virulence determinants is a large RTX-like toxin (GtxA),which has been demonstrated to induce a strong leukotoxic effect on avian macrophages.A number of fimbria of different sizes and shapes,particularly the F17-1ike fimbriaes,appear to be common in a diverse selection of G.anatis strains.The capsular material expressed possibly involved in serum resistance,metalloproteases capable of degrading immunoglobulins,hemagglutinins,and all factors which may promote biofilm formation are likely linked to the virulence of G.anatis.This review summarized the putative virulence factors described for this bacterium to date.

Objective To apply robotic surgery of early ovarian malignancy tumors clinically and evaluate its feasibility in management for early ovarian cancer. Methods Using the da Vinci robotic surgical system, seven patients with early ovarian malignancy tumors (stage Ⅰ) underwent robotic surgery from April 2012 to September 2013. The average age was 45.7 years. Robotic surgeries approaches contained salpingo-oophorectomy,para-aortic lymphadenectomy, pelvic lymphadenectomy, omentectomy and appendectomy. Perioperative and follow-up clinical data were recorded. Results All robotic surgeries were successfully completed without the conversion to laparotomy. The mean operative time was 225 minutes (100-330 minutes). The average estimated blood loss was 171 ml (20-600 ml). No patients received blood transfusions. No intraoperative and postoperative complications were observed. The average number of pelvic lymph node dissected were 18.3 (11-34). The average number of para-aortic lymph node dissected were 3.7 (3-4). The mean follow-up time was 26.0 months after surgery (20-36 months). Currently, all patients had no tumor recurrence and survived. Conclusion Robotic surgery is feasible as a novel alternative approach in the treatment of early ovarian malignancy tumors.

Objective To observe the effects of modified Jianpi Yishen Decoction on urinary osteopontin (OPN) in calcium oxalate nephrolithiasis patients after percutaneous nephrolithotomy (PCNL) or ureteroscope lithotomy (URL);To clarify the mechanism of modified Jianpi Yishen Decoction on the prevention of calcium oxalate kidney stones. Methods Totally 116 calcium oxalate nephrolithiasis patients were randomly divided into trial group (62 cases) and control group (54 cases). The trial group took modified Jianpi Yishen Decoction every other day, while the control group took potassium sodium hydrogen citrate granules three times a day. The concentrations of OPN, urinary calcium and urinary oxalic acid of the patients in the two groups were observed before treatment and 2 weeks and 4 weeks of treatment. Results The concentration of urinary OPN of 2 weeks and 4 weeks of the treatment in the trial group was significantly increased compared with before treatment (P<0.05), and the difference was statistically significant compared with the control group (P<0.05). The concentration of urinary OPN in the control group had no significant change after treatment (P>0.05). The differences in the concentrations of urinary calcium and urinary oxalic acid of the two groups between before and after treatment were not significant (P>0.05). Conclusion Modified Jianpi Yishen Decoction can effectively restrain the formation of the calcium oxalate stones by increasing the level of urinary OPN, which demonstrates effective prevention in the calcium oxalate nephrolithiasis patients after PCNL or URL.

Objective To explore the effects of targeted silencing of the chemokine receptor 7 (CXCR7)gene on the invasion and migration of the melanoma cell line M14. Methods Western-blot analysis was performed to determine the protein expression of CXCR7 in melanoma cell lines M14 and A375, and CXCR7-overexpressing M14 cells were used in this study. Cultured M14 cells were divided into three groups: experimental group transfected with a small interfering RNA(siRNA)targeting CXCR7(CXCR7-siRNA), negative control group transfected with a negative control siRNA, blank control group receiving no treatment. Real-time quantitative PCR and Western-blot analysis were conducted to determine the mRNA and protein expressions of CXCR7 respectively in M14 cells, Transwell chambers were used to evaluate the invasive activity of M14 cells, and wound healing assay to estimate the migratory activity of M14 cells. Results The experimental group showed significantly decreased mRNA and protein expressions of CXCR7 compared with the negative control group and blank control group (CXCR7 mRNA: 0.412 ± 0.023 vs. 1.211 ± 0.117 and 1.000 ± 0.102, F = 30.068, P = 0.001; CXCR7 protein: 0.144 ± 0.005 vs. 1 and 1.016 ± 0.004, F =11 485.5, P = 0.000). The number of M14 cells crossing the polycarbonate membrane per high-power field (× 200)was significantly smaller in the experimental group than in the negative control group and blank control group (20.617 ± 1.503 vs. 42.000 ± 6.018 and 43.627 ± 2.152, F = 32.416, P = 0.001). Similarly, the number of migrating M14 cells in wound healing assay was significantly decreased in the experimental group compared with the negative control group and blank control group (15.00 ± 1.10 vs. 44.90 ± 2.20 and 45.30 ± 2.30, F = 2 411.945, P = 0.000). Conclusion Targeted silencing of the CXCR7 gene can significantly inhibit the invasion and migration of M14 cells in vitro, which may provide a potential target for the treatment of cutaneous melanoma.
