Objective To evaluate the effect of free NgR-modified bone marrow stromal cell (BMSC) transplantation on axon regeneration in rats after spinal cord injury. Methods Genes encoding free NgR protein were cloned and transduced into BMSCs at passage 3 using a lentivirus vector.Indirect immunofluorescence was used to detect the expression of free NgR protein.Meanwhile a spinal cord contusion model was established in 36 adult Sprague-Dawley rats at the T10 segment.The rats were then divided randomly into an experimental group and a control group.NgR + BMSCs were transplanted into the injured site 1 week post-trauma in the experimental group.BMSCs were also transplanted at the same time into the control group.Expression of free NgR at the injury site was detected by immunohistochemical staining at 1 week post-transplantation.The functional recovery of both groups was evaluated at 4 and 6 weeks post-transplantation.Longitudinal sections of the spinal cord were studied for axon regeneration using horseradish peroxidase staining. Results Expression of free NgR was found in the cell plasma of BMSCs by indirect immunofluorescence post-transfection.Positive immunohistochemical staining for NgR was found at the transplant site in the experimental group 1 week post-transplantation.Better axon plasticity could be observed in the experimental group.The Basso-Beattie-Bresnahan scoring of the experimental group was significantly higher than that of the controls at both observation times. Conclusions Free NgR-modified BMSCs can prompt injured axons to regenerate and thus to promote the recovery of neurological function.This might provide a new strategy to treat spinal cord injury.

Wnt signaling pathway is not only closely related to tumor invasion and metastasis,such as cancer cells migration and adhesion,extracellular matrix degradation,and angiogenesis,but also plays an important role in self-renewal,proliferation and differentiation of tumor stem cells.Progress has been made in high specific genes drug development and targeted therapy against the Wnt signaling pathway.

AIM: To study the effects of dexamethasone (DXM) on intracellular expression of TH1/TH2 cytokines and the mechanism of that during the development of asthma. METHODS: Eighteen BALB/c mice were divided into 3 groups at random: control group, asthma group, and DXM treated group, with 6 mice in each. The expressions of T-box expressed in T cells (T-bet) and GATA-binding protein-3 (GATA-3) in lung tissue were detected by Western blotting. The expressions of intracellular cytokines interleukin-4 and interferon-? in CD4+ T cell were measured by flowcytometry.RESULTS: The results of flow cytometry indicated that the ratio of intracellular cytokines IL-4/IFN-? in CD4+ T cells in asthma group was much higher than that in control group (P

Objective To investigate the effects of extract of Ginkgo biloba leaves EGb761 on 1-methy-l 4-phenylpyridium (MPP+)-induced injury in human neuroblastoma SH-SY5Y cells; To discuss its mechanism of action.Methods Cell culture method was used and SH-SY5Y cell damage model was induced with different concentrations of MPP+ to build Parkinson’s disease model in vitro. The experiment was divided into control group, MPP+ model group, low-, medium-, and high-dose EGb761 groups. The survival rate was determined by MTT assay, and the apoptotic rate was detected by flow cytometry according to AnnexinV apoptosis detection kit. The cell morphology was observed by inverted microscope. NO content in SH-SY5Y cells was detected by Nitric acid reduction method.Results Compared with the control group, the survival rate of SH-SY5Y cells decreased and the apoptotic rate and NO content increased in the model group (P<0.05); Compared with the model group, the survival rate of SH-SY5Y cells increased and the apoptotic rate and NO content decreased in the low-, medium- and high-dose EGb761 groups (P<0.05).Conclusion EGb761 can protect MPP+-induced SH-SY5Y cell from damage by the inhibition of the content of NO free radical.

Objective To analyse the effect of endoscopic thoracic sympathectomy of palma-plantar hyperhidrosis. Methods Between January 2006 and January 2009,77 cases with palma-plantar hyperhidrosis were operated by thoracoscope. Fifty-two cases of palma-axillary-plantar hyperhidrosis were performed sympathectomy of T2-T4 and 25 cases of palma-plantar were performed sympathectomy of T2-T3.Bilateral procedures were completed in the same position. Results After operation palmar hyperhidrosis and armpits hyperhidrosis all were cured. Of soles, 7 cases were completely dry, 34 cases nearly dry, 32 cases unchanged and 4 cases worse. There was no significant difference in the change of plantar hyperhidrosis between sympathectomy of T2-T3 and T2-T4 (P > 0.05). Conclusions Bilateral single port for endoscopic thoracic sympathectomy produces slighter trauma and patients easily accept it. Plantar sweating can be relieved or nearly relieved in partial patients after thoracic sympathectomy. There is no difference in the effect of plantar hyperhidrosis between sympathectomy of T2-T3 and T2-T4.

[Summary] To investigate the association of rs2282679 A/C polymorphism in vitamin D binding protein gene with vitamin D deficiency in 1 216 participants.A standardized questionnaire was applied to collect information on alcohol consumption,smoking habits,and use of medications.Serum 25-hydroxyvitamin D [25 (OH) D] was determined by radioimmunoassay.Vitamin D binding protein genotypes were determined by SNaPshot method.1216participants included 457 women(37.6%),478 (39.3%)with vitamin D deficiency [25 (OH) D<50 nmol/L],and 386 (31.7%) overweight/obese participants.The frequencies of rs2282679 CC,AC,and AA genotypes were 8.7%,41.0%,and 50.3%,respectively.The distributions of genotypes and alleles differed significantly between participants with sufficient vitamin D and those with vitamin D deficiency (P < 0.05).There were significant differences in the serum levels of 25 (OH) D between three genotypes before and after being adjusted for covariates (P<0.01).AA had a 22% (OR =0.78,95% CI 0.65-0.93,P =0.006) lowered risk of vitamin D deficiency compared with the whole studied population.Compared with CC genotype,AA had a 36% lowered risk of vitamin D deficiency(OR =0.64,95 % CI 0.42-0.98,P =0.006),while there was no significant difference between AC and CC genotypes(OR=0.87,95% CI0.57-1.34,P=0.53).In conclusion,the vitamin D binding protein rs2282679A/C polymorphism was significantly associated with serum level of 25 (OH) D and risk of vitamin D deficiency.
