UNLABELLEDTo reduce the huge labor-cost in the screening in traditional monoclonal antibody generation, We established a new system for monoclonal antibody generation integrating with protein array. BALB/c mice were immunized by eight recombinant proteins respectively, and the positive hybridoma cells were obtained by cell fusion and ELISA screening. All the eight kinds of positive hybridoma cells were mixed, cloned, screened by protein array, and definite dilution cloned.
RESULTS175 single cell clones were obtained by complex cloning, and 119 of those were positive clones. Then 8 positive cell lines were generated by the following 2 rounds definite dilution cloning. By comparing with the traditional method, we got 8 monoclonal antibodies using the combined protein array screening and multiplex cloning method in 1 cycle, and fewer amounts of antigens were used. As a result, the combined protein array and multiplex cloning method could be used as an economical, rapid and simple tool applying in high throughput monoclonal antibody generation.

OBJECTIVETo observe the homing and differentiation of marrow-derived mesenchymal stem cells (MSC) transplanted intravenously in smoke inhalation injured rabbits.
METHODSThirty-two New Zealand big ear rabbits were divided into normal control group (NC), inhalation injury group (II), normal control + MSC treatment group (NM), and MSC treatment group (MT) according to the random number table, with 8 rabbits in each group. Rabbits in NC group were injected with 10 mL phosphate buffered saline (PBS) via ear marginal vein. Rabbits in NM group were injected with 10 mL PBS containing the third generation MSC labeled by BrdU (1 × 10(7) per 10 mL PBS) via ear marginal vein. Severe smoke inhalation injury model was reproduced in the other two groups, among them rabbits in II group were treated as rabbits in NC group, rabbits in MT group treated as rabbits in NM group. On the 7th and 28th day post treatment (PTD), lung tissue and trachea tissue were harvested from four groups for observation on injury with HE staining. Homing of MSC in injured tissue was observed with immunohistochemistry staining. The differentiation of MSC into functional cells was observed with immunohistochemical double staining of combining nuclear marker BrdU with lung (trachea) membrane-specific marker aquaporin-5 (AQP-5), alkaline phosphatase (AKP), CD34, and cytokeratin respectively.
RESULTS(1) MSC homing in lung and trachea tissue was observed in MT group on PTD 7, which was not observed in NM group. (2) AQP-5, AKP, and CD34 positive MSC were observed in lung tissue in MT group on PTD 28, while cytokeratin positive MSC was not observed in trachea tissue. No positively marked MSC was observed in NM group. (3) Injury in lung and trachea was less severe in MT group than in II group; and the proliferation of fibroblasts was less in MT group.
CONCLUSIONSIntravenous injection of MSC to rabbits with smoke inhalation injury can migrate to lung and trachea tissue at obviously inflammatory site, and differentiate into alveolar epithelial cells typeI and II, and pulmonary vascular endothelial cells, which may participate in the process of tissue repair in smoke inhalation injury.

Taking the genome DNA of Infectious Bovine Rhinotracheitis Virus (IBRV) as the template, the gG gene was amplified with PCR and cloned into the T cloning vector pMD18-T. After being identified by restriction digestion and DNA sequencing, the insert was subcloned into the expression vector pGEX-KG. Sodium docecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) and Western blot assay showed that this gene was expressed as both soluble form and inclusion body by the transformed E. coli BL21 strain (DE3). The fusion protein was purified and used as the coating antigen to develop the indirect Enzyme-Linked Immunosorbent Assay (ELISA). Comparison between this gG-ELISA and commercial IBRV gB-ELISA Kit (IDEXX) was made in the detection of 380 cow serum samples. The results demonstrated an agreement of 92%. By using this novel gG-ELISA, 1248 cow serum samples were tested and the average positive rate of IBRV antibodies for imported cows is 21.7%, while the positive rate ranged greatly from 0.0%-41.5% for Hubei local Chinese Black and White Dairy Cows.

OBJECTIVETo study the effect of BAM bone grafting combined with inactivated autologous porous bone flap in repairing skull defect in rats.
METHODSSeventy-two Wistar rats with skull defect were randomly divided into control group, inactivated autologous bone flap group (AB group), BAM bone-induced artificial bone material group (BAM group), and inactivated autologous bone flap with BAM bone-induced artificial bone group (BAM+AB group). The bone healing was evaluated with micro-CT and the new bone formation was assessed with histological staining at 1, 2, and 3 months after modeling.
RESULTSInactivated porous bone flap combined with BAM bone-induced artificial bone effectively induced vascular and fibrous tissue regeneration and osteogenesis in the cranial defects. With the inactivated porous bone flap as the scaffold, BAM bone-induced artificial bone obviously promoted the restoration of the skull appearance in the rats with cranial defects.
CONCLUSIONInactivated autologous bone flap group and BAM bone-induced artificial bone material can promote skull healing and restoration of the original skull appearance, and can be used for reconstruction of the local anatomy of the skull surface.

Objective:To explore the mechanism of hypertension inducing erectile dysfunction(ED)using transcriptomics and network pharmacology.Methods:We randomly divided 12 male rats with spontaneous hypertension(SHT)into an L-arginine(LA)group(n=6)and an SHT model control(MC)group(n=6),took another 6 Wistar Kyoto male rats as normal controls(NC),and treated the animals in the LA group by intraperitoneal injection of LA at 400 mg/kg and those in the latter two groups with physio-logical saline,once a day,all for 7 days.Then we observed the blood pressure and penile erection of the rats,and determined the ex-pressions of the cGMP/PKG signaling pathway-related proteins and mRNAs in different groups using ELISA,Western blot and RT-qPCR.Results:Transcriptomics combined with network pharmacology showed that the cGMP/PKG signaling pathway played a key role in hypertension-induced ED.In vivo animal experiments revealed a significantly lower frequency of penile erections in the MC than in the NC group(1.33±0.52 vs 2.67±0.51,P<0.05).The protein expressions of eNOS,PKG and sGC were markedly de-creased in the model controls compared with those the normal controls(P<0.05),but remarkably upregulated in the LA group com-pared with those in the MC group(P<0.05).Conclusion:Hypertension decreases the expressions of eNOS,NO,sGC,cGMP and PKG proteins and the level of testosterone by inhibiting the cGMP/PKG signaling pathway,which consequently suppresses the relaxa-tion of the penile vascular smooth muscle and reduces erectile function.
