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.

Methods:The standard variation was studied by comparing and analyzing every version standard for the same drug to look for the change rule. Results:The standard items of the drug had some change rules in indicator numbers, testing methods and limits according to the order of issue time. The standard development trends could be described by making specific indicators and drawing evolution figures of the items. Conclusion:By the standard analysis model, the same item of the same drug can be compared to provide the reference for data collecting of experts. Meanwhile, formulate standard can be calculated to provide the reference for the standard improvement without drug standards.

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 clone mcp1, mcp2 and mop3 genes that encoding methyl-accepting chemotaxis proteins(MCP) of Campy/obacter jejuni for construction of their prokaryotic expression systems, and to establish chemotactic model in vitro of the microbe for determining chemotaxis-inducing substances and to understand relationship among MCPs and chemotactic inducers. Methods The segments of mep1, mcp2 and mcp3 genes were amplified by PCR and then sequenced after T-A cloning. Prokaryofic expression systems of the genes were subsequently constructed. SDS-PAGE pins Bin-Rod Gel Image Analyzer were used to examine the expression of target recombinant proteins rMCP1, rMCP2 and rMCP3, and Ni-NTA affinity chromatography was performed to purify the rMCPs. Rabbits were immunized with each of the three rMCPs to obtain antisera. Immunodiffusion assay was performed to measure the titers of antisera. IgG in each of the antisera were extracted by ammonium sulfate precipitation and DEAE-32 ion exchange chromatography, and IgG F(ab')2 were then prepared by pepsin enzymolysis and Sephadex G-100 chromatography. Chemotactic model in vitro of C. jejuni based on HAP( hard-agar plus) method was established to determine the chemo-taxis-inducing effect of eight candidate substances. Chemotaxis inhibition test based on IgG F(ab')2 bloc-king was applied to determine the function and diversity of MCPs. Results The segments with expected si-zes amplified from mcp1, racp2 and mcp3 genes were obtained by PCRs, and their nucleotide and putative amino acid sequences were completely same as the reported. The constructed prokaryotic systems could effi-ciently express rMCPs with the yields about 10% of the total bacterial proteins. Immunization with rMCP1, MCP2 and rMCP3 enables the rabbits to produce specific antibody. All the antisera had 1: 4 immunodiffusion titers. Both bovine bile and sodium deoxycholate(DOC) were able to induce ehemotactie movement of C. je-juni in a dosage-dependent manner ( P < 0.05 ). When MCP1 and MCP2 were blocked with their IgG F(ab')2, the ehemotaetic ability of C. jejurd were remarkably decreased (P <0. 05). However, MCP3 blocking did not affect the chemotaxis ( P > 0.05 ). Conclusion The C. jejuni MCPs are successfully ex-pressed in this study. Bovine bile and DOC are the inducers for chemotaxis of C. jejuni, and MCP1 and MCP2 are involved in the process of ehemotaxis iadueed by DOC.

Objective The aim of this study was to investigate the femoral head trabecular heterogeneity in Chinese male patients with osteoporotic fracture and their effects on osteoporotie fracture.Methods Human femoral heads were obtained from 11 male osteoporotie fracture (OP) patients ranged from 51 to 82 years old [average age (65±9 ) years old], and 7 male trauma ( TM ) patients ranged from 46 to 75 years old [average age (61±11 ) years old] who underwent total hip arthroplasty within two hours after either osteoporotic or trauma hip fracture.The OP was defined as having a fragility fracture.After laying femoral head as living body position and locating mark, nine trabecular specimens were obtained from femoral heads, each of 6 mm × 6 mm× 7 mm.The cortical shell was not included in each specimen.One cube was selected as the primary compressive trabecular region and the other 8 specimens as non-primary compressive trabecular region.These cubes were scanned using high-resolution microcomputed tomography scanner (μCT).After scanning, the data of total cubes, primary compressive trabecular region and noncompressive trabecular region were used for analysis by t test.Results In OP group volumetric bone mineral deosity(vBMD) [( 182.15±66.00) mg/mm3 vs (223.97±70.92) mg/mm3, t =3.041], tissue bone mineral density (tBMD) [(538.76±64.72) mg/mm3 vs (580.01±63.86 ) mg/mm3, t = 3.160],bone volume fraction (TV/BV) [(0.22 ± 0.06) % vs (0.26 ± 0.07 ) %, t = 2.821], trabecular thickness (Tb.Th.) [( 161.07 ±42.75 ) μm vs ( 205.47 ± 74.44 ) μm, t = 3.233] were significantly decreased while bone surface/bone volume ( BS/BV ) [( 13.75 ± 2.55 ) mm-1 vs ( 12.28 ± 2.70 ) mm-1, t =-2.777] was significantly increased in the non-primary compressive trabecular region than that in the primary compressive trabecular region ( P < 0.05 ).vBMD [( 182.15 ± 66.00) mg/mm3 vs ( 248.05 ±105.48) mg/mm3, t = - 3.598], tBMD [(538.76 ± 64.72) mg/mm3 vs ( 570.54 ± 100.32) mg/mm3,t=-2.108],TV/BV [(0.22±0.06) % vs (0.28±0.12) %, t= -3.466], Tb.Th.[(161.07±42.75) μm vs (200.31 ±96.63) μm, t= -2.866], trabecular number (Tb.N.)[(1.46±0.23)/mm3 vs ( 1.57 ± 0.29)/mm3, t = - 2.396] were significantly decreased while trabecular separation ( Tb.Sp.) [(780.82 ± 144.85 )μm vs ( 653.09 ± 119.64) μm, t = 5.470], degree of anisotropy (DA) ( 1.57±0.20 vs 1.47±0.18, t = 2.930 ) were significantly increased in OP than in TM in the non-compressive trabecular region( P < 0.05 ).No significant differents were found between OP and TM for any of the parameters measured in the primary compressive trabecular region.Tb.Th.[(199.37±68.22)μm vs (176.33 ±71.21 )μm, t = 2.060,P < 0.05] were significantly increased in the primary compressive trabecular region than that in the non-primary compressive trabecular region and no significant differences were found in the other parameters in the all 18 specimens.Conclusions The femoral head trabeculae had a heterogenic distribution in OP.Bone loss in OP primarily takes place in non-compressive trabecular region.Femoral neck fracture cannot be prevented though the bone microstructure do not loss in the primary compressive trabecular region.Tb.Th.in the femoral head could be an interesting parameter which is closely related to the femoral neck fracture.

Objective To investigate osteocyte density as a potential index of bone biomechanical property. Methods Forty 7-month-old female Sprague-Dawley rats were randomly group (EST) and sham operation group (SHAM). At 15 weeks postoperation, the compression test was performed on L5 vertebral body and micro-computed tomography (μ-CT) was used to estimate the three-dimensional bone mineral density (BMD) and three-dimensional microstructure parameters of L6 vertebral body. After fatigue damage testing, the L6 vertebral body was bulk-stained in 1% basic fuchsin and embedded in methylmethacrylate. Mounted bone slices were used to measure microcrack parameters and osteocyte density. Results At 15 weeks postoperation, osteocyte density (Ot. N/T. area) was significantly decreased in OVX group compared with SHAM group and EST group [(1268. 1 ±191.2)/mm2 vs. (1760. 8 ± 376.6)/mm2 and (1550. 9± 202.2)/mm2, F = 3.513,P<0. 05]. Maximum load (ML) was significantly decreased and the length of microcrack (Cr. Le) was significantly increased in OVX group compared with SHAM group, EST group and GEN group [(84. 4±16.9)N vs. (110.3±25.6),(103. 9±15. 8)and(110.1±4. 9)N; (58. 1±6.8) μm vs. (24.2±8. 1), (36. 5±9. 7)and(28.5±7. 5)μm, F=9. 561,3. 179, all P<0. 05]. Compared with SHAM group and EST group, bone trabecula connection density (Conn. D) was significantly decreased and trabecular separation (Tb. Sp) was significantly increased in OVX group [(47.4±7.4) m-3 vs. (71.8±16.0)and (74.0±12.7)m-3;(315.0±32.7)μm vs. (222. 5±21.7)and (273.3± 50.0)μm, F=7. 635,7. 007, all P<0. 05]. Bone mineral content (BMC) was lower in OVX group than that in SHAM group[(6.5±2. 2)g vs. (7. 9±1.2)g, P<0. 05]. When data in four groups were overall analyzed, Ot. N/T. Ar was positively correlated with ML, Conn. D and BMC (R2 = 0. 7874, 0. 1153, 0. 1309, all P<0. 05), but was negatively correlated with Cr. Le and Tb. Sp (R2 =0. 5738, 0. 3964, both P < 0.05). Conclusions Osteocyte plays a crucial role in maintaining bone biomechanical property and osteocyte density may be considered as a useful indicator for assessing bone biomechanical property.
