Objective To analyze inducing factors of acute left heart failure(AHF) of emergency case.Methods According to different age and gender,the inducing factors of AHF of 211 patients were retrospectively analyzed.Results Infection(42.99%) was the most important inducing factors of AHF in all the four age-groups,but as for patients elder 80,the arrhythmias was also play an important part in inducing factors of AHF.The difference of inducing factors was found among the four age-groups.but the difference of inducing factors was not found between the two gender-groups. Conclusion Since the most important inducing factors of AHF of emergency case was infection,anti-infectives is important for preventing and controlling AHF.

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

[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.

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.
