Objective To demonstrate the mapping of the brachial plexus by means of high resolution sonography. Methods Eight healthy adult volunteers (three women and five men) underwent bilateral sonographic examination to assess the nerve structures of the brachial plexus from the extraforaminal part to the axillary part. Results A satisfactory sonographic demonstration was shown in all the volunteers. The subclavian and deep cervical arteries were useful landmarks for this mapping. Sonography was also reliable in depicting the level of the C7 vertebra because of the absence of the anterior tubercle from its transverse processes. Conclusion The brachial plexus can be mapped with high resolution sonography, for it may increase the diagnostic rate of brachial plexus injury.

Objective:To evaluate functional recovery of nerve and muscle after end-to-side neurorrhaphy.Methods:10 SD rats were randomly and evenly devided into group A and group B.Right common peroneal nerve was amputated in all the rats.Then the distal stump was sutured to the ipsilateral tibial nerve by the end-to-side way through a epineurial window in group A. The right common peroneal nerve was severed in group B as denervated control.After 1.5 months all the rats were subjected to walking track analysis,histological and ultrastructure observation.Results:In group A peroneal nerve index (PFI) achieved -41.634,density of collateral axons 51.437?12.041/1 000 ?m 2,synapsin (SYP) 439?120.5.In group B PFI was -100,SYP 0. In normal control PFI was 0, density of collateral axons 18.847?1.078/1 000 ?m 2,SYP 842?84.7.Conclusion:End-to-side neurorrhaphy may induce nerve sprout plenty of collateral axons.The axons can reach target muscle to reconstruct functional neuromuscular junction,and recover the function of the muscle in some degree.

Objective To investigate the influence of self-harmony in visiting first grade female college students on admission adaptability and mental health to provide the theoretical and practical basis for preventing the mental problems and college mental health education work.Methods A total of 354 first grade female college students making the appointment for psychological consultation were selected as the research subjects and measured with the Self Consistency and Congruence Scale(SCCS),Symptom Checklist 90 (SCL-90) and Chinese College Student Adaptation Scale(CCSAS).Results The visiting first grade female college students had the psychological problems such as obvious social anxiety and accompanying with anxiety,depression and other the negative emotions,and unreasonable expectations of self-experience,starchiness and rigidity of self-harmony existed.The various factors of self-harmony and total score in the first grade female college students had different degrees of significant correlation with the various factors of admission adaptability and mental health(P<0.05);the disharmony between self and experience had a significantly positive predictive effect on the visiting first grade female college students′ mental health(P<0.05),but which had a significantly negative predictive effect on the admission adaptation(P<0.05).The admission adaptation had an incomplete mediating effect between self experience disharmony and mental health.Conclusion Self-harmony promotion contributes to improve female college students′ admission adaptability and mental health level.

Objective To compare the efficacy of chronic hypertrophic rhinitis by partial inferior turbinectomy and using semiconductor laser surgery .Methods The efficacy of 53 chronic hypertrophic rhinitis patients with partial inferior turbinectomy(groupⅠ) and 62 patients treated with semiconductor laser surgery(groupⅡ) were analyzed retrospectively.Results the total effective rate of the groupⅠ treated by semiconductor laser surgury was 87 1% and groupⅡ treated by partial inferior turbinectomy was 90 4%. There was no significant difference (P

Objective To investigate the clinical effect of Tiotropium Bromide Powder for Inhalation combined with mental intervention in the treatment of chronic obstructive pulmonary disease in stable period. Methods 80 patients with stable chronic obstructive pulmonary disease treated in our hospital from January 2015 to January 2017were divided into two groups according to the different treatment methods.The control group was treated with conventional methods, the observation group was treated with routine + Tiotropium Bromide Powder for Inhalation + psychological intervention therapy.The clinical curative effect and the improvement of clinical symptoms were recorded and analyzed. Results The clinicalcurative effect of the observation group was better than that of the control group, the improvement of clinical symptoms was better than that of the control group,the difference was statistically significant (P<0.05). Conclusion The effect of chronic obstructive pulmonary disease patients choose conventional treatment+Tiotropium Bromide Powder for Inhalation + psychological intervention mode is significant, can improve clinical symptoms, improve the therapeutic effect and prognosis in the near future and far, worthy of clinical widely used In the treatment of patients with chronic obstructive pulmonary disease in stable phase.

Objective To determine the expression of two neuron developmental associated genes induced by hyperphenylalanine.Methods Primary embryonal rat cerebral cortical neurons were cultured for three day and cells induced by hyperphenylalanine for 12 hours.Real time quantitative RT-PCR was used to determine the influence of hyperphenylalanine on the expression of GAP-43 and Go?1 genes.Results GAP-43 mRNA was upregulated to 2.25 times and Go?1 was downregulated to 3.31 times by hyperphenylalanine.Conlusion Hyperphenylalanine may interfere the normal development of cerebral cortical neurons through influencing the expression of GAP-43 and Go?1 genes.

Growth differentiation factor(GDF)-15,a distant member of the transforming growth factor-? cytokine superfamily,is a powerful cardioprotective factor.Many studies have demonstrated that serum GDF-15 level is a novel marker closely associated with the diagnosis,risk stratification,and prognosis of several cardiovascular diseases.This article mainly reviews the characteristics of GDF-15 and its multifunction in cardiovascular diseases.

Objective To investigate the expression of human defensin-alpha1-3 (HNP1-3) in breast cancer and in normal tissues and determine whether there exists a relationship between HNP1-3 expression and clinicopathologic features.Methods Immunohistochemical staining was used to detect the expression levels of HNP1-3 in 59 breast cancer specimens,and 20 normal tissues (fibroadenoma of breast or tumor-adjacent tissues).The relationship of the expression levels of HNP1-3 with patient’s age,clinical stage,histological grade,lymph node metastases and expression of PR/ER/C-erB-2 was analyzed.Results High level expression of HNP1-3 (95%) was expressed in those normal breast tissues.Different expression of HNP1-3 was found in breast cancer specimens and closely correlated with tumor histological stage and lymph node metastases (P

Objective To discuss the matching method of irregular device for radiological equipment. Method Related experiences were summed up. Result A set of interventional protective device matching DSA was developed through tripartite corporation. Conclusion The matching method is beneficial to equipment management.

OBJECTIVE Research the therapeutic effectiveness of combination Imipenem and teicoplanin to treat septicemia due to interspace of lumbar vertebrae Infection complicated pulmonary abscess and the method of diagnosis,prevention and cure of Secondary interspace of lumbar vertebrae Infection.METHODS The successful cure case-report that severe postoperative interspace of lumbar vertebrae infection complicated blood-borne pulmonary abscess used small needle knife to treat Lumbar intervertebral disc protrusion(LIDP) were reviewed.RESULTS Unstandard asepsis technique and invasive operation long time operation,too mang damage of tissue in operation,patient weak,diabetes,glucocorticoid,lacking postoperative anti infection therapy etc.Lumbocrural pain were found aggravated,high fever,blood sedimentation increased,CRP heightened.CONCLUSIONS Strict asepsis,sufficient preoperotive preparation,Standard operation,less damage,can reduce interspace of lumbar vertebrae infection rate.Strict asepsis and less damage in the operation can reduce the incidence of intervertebral disc space infection.
