ObjectiveTo explore the relationship between ORMDL3 gene polymorphism and Asthma in children.Methods178 cases of children with asthma were divided into mild group and severe group, and 129 cases of children were treated as normal control group who tested blood samples in the PLA General Hospital and its Affiliated Hospital in the recent 4 years. ORMDL3 gene locus rs7216389 genotype was detected, including PCR, restriction endonuclease analysis and bio-statistical aspects of analysis.ResultsThere was significant difference (P<0-05) in 3 genotypes (CC\TC\TT). There was no significant difference in TT between the mild group and the control group (P>0-05). The rate of severe group was higher than that in the mild and the control groups(P<0-05). Asthmas in children showed higher T allele frequency.ConclusionORMDL3 gene polymorphism showed a certain relevance with asthma in children.

Objective To investigate the altered expression of muscarinic receptor 2 (M_2 receptor) in the pedunculopontine nucleus (PPN) of Parkinson's disease (PD) model rat by immunocytochemical technique and explore the role of M_2 receptor in etiopathogenesis and pathophysiological changes of PD. Methods Sixteen healthy SD rats were divided randomly into two groups. Rat monoclonal antibody against the M_2 receptor was used. Then we used positive cell counting and optical density as indicators to analyze the altered expression of M_2 receptor in PPN of PD model rats. Results The counting of M_2 receptor positive cells in the PPN was not obviously changed in normal rats and the unlesioned side of PD rats (P>0.05), whereas a significant decrease was observed when compared to that in normal rats and the lesioned side of PD rats, respectively (P<0.05). However, the positive intensity in the three groups did not differ significantly. Conclusion The results indicate that there was a degenerative death or receptor loss of M_2 receptor positive cells in the lesioned PPN of PD rats. The expression intensity of M_2 receptor positive cells without degenrative death or receptor loss was not affected. It was also found that the factor affecting the change of M_2 receptor positive cells in the PPN involved only one side.

Objective To investigate the clinical efficiency of branch artery of the sural medial gastrocnemius muscle flap combine with sural nerve nutritional vessel axial.Methods From February 2006to March 2010,according to the position and size of the soft tissue defects,the muscle flap combined with branch artery of the sural medial gastrocnemius and sural nerve nutritional vessel axial were desingned and obtained to repair 7 cases of sofi tissue defects of the upper-region of the tibial.The flap size ranged from 8.0 cm × 8.0 cm to 12.0 cm × 10.0 cm.The vessel pedicle of branches ranged from 1.8-3.0 cm.The distribution of the vessel pedicle of branches ranged from 10.0-17.0 cm on the distant popliteal fossa,and ranged from 2.0-5.0 cm on the back of medial line.Results The outline and function were satisfactory during 6-15 months follow-up.Conclusion The blood supply of this flap is reliable without sacrifice of major arteries.Flap elevation is easy.It can transfer to a long distance and can repair large skin defects.It is very useful in repairing upper-region of the tibial large soft tissue defect.

Objective To assess the predictive value of short-latency somatosensory evoked potential (SSEP) in the acute phase of stroke regarding functional recovery. Methods One hundred and fifty stroke patients were included. SSEPs were recorded on the first 7 days after stroke, and the patients were then stratified into groups with absent, abnormal and normal responses. Clinical state was determined according to the NIH stroke scale (NIHSS), the Fugl-Meyer assessment (FMA), the modified Barthel index (MBI) and the modified Rankin scale (MRS). SSEP was followed up at 1, 3, 6 and 12 months. Results The NIHSS and FMA scores were significantly different comparing any two groups or at different times in the same group. The median SSEP N20 latency and tibial nerve SSEP P40 latency during stroke were positively correlated with MRS scores 12 months later but negatively correlated with MBI results. The ADL results 12 months after stroke were used to evaluate functional recovery, and the prediction rate of the SSEP results alone was 40.8% , however the rate improved to 44.2% when SSEP results were combined with FMA scores and became 46.1% when SSEP, FMA and MRS results were all considered. Conclusion SSEP has independent predictive value regarding functional recovery after stroke. Combined assessment of initial FMA, MRS and SSEP substantially improves the predictive power for stroke prognosis.

Objective To investigate changes in the firing activities of nucleus accumbens (NAc)neurons and their response to 5-HT7 receptor stimulation in a rat model of Parkinson’s disease (PD).Methods The firing activities and response of NAc neurons to 5-HT7 receptor agonist in PD rats were recorded by in vivo electroneurophysiology and neuropharmacology and then were compared with those in the sham group.Results The mean firing rate of NAc neurons was (5.46 ±0.88)Hz in the sham rats and (3.77 ±0.48)Hz in the PD rats. The firing rate of NAc neurons increased significantly compared with that in the sham rats (P <0.05).In PD rats, 65% of NAc neurons fired in bursts and 35% fired irregularly.However,in the sham rats,57.5% of NAc neurons fired in bursts and 42.5% fired irregularly.There was no significant difference in the firing pattern of NAc neurons between the PD and sham rats (P >0.05 ).Systemic administration of 5-HT7 receptor agonist AS1 9 increased the firing rate of NAc neurons in the sham and PD rats.This excitation was significant at a high dose of 1 60 μg/kg for NAc neurons in the sham rats (P <0.05).However,the excitation produced by AS1 9 was significant at a high dose of 80 μg/kg in PD rats (P <0.05).The cumulative dose-produced excitation in the PD rats was lower than that in the sham rats.The effects induced by AS1 9 were reversed by the 5-HT7 receptor antagonist SB269970 in both groups.Conclusion The reinforced firing activity of NAc neurons might be mediated by 5-HT7 receptor in the neurons of PD rats.
