Objective: To evaluate the effect of flotation therapy on the attention of undergraduates. Method: Subjects were 53 undergraduates (26 male, 27 female). They were randomly divided into 5 groups. Group 1,2,3 and group 4 were flotation groups and group 5 was control group. Each subject finished four therapies. Visual attention attribution and diversion (T5) and bilateral two- choice reaction time (T8) were used as the indexes. Result: As a whole, the T5 and T8 times of the subjects in the flotation groups were shortened in the course of the therapy. The promotion of attention in the male subjects was better than that in the female subjects. There was no significant difference between the changes of bilateral two-choice reaction time. The promotion in the flotation subjects was significantly better than that in the control subjects and it could not be explained totally by practice effect. Conclusion: The attention of the subjects can be promoted by flotation therapy. This study could not support the assumption that flotation therapy could promote the function of right brain as some prior studies declared.

Objective To retrospective analysis of the clinical effect and complications of the semi-laminectomy approach on the treatment of intra-spinal tumor.To summarize the endoscopic treatment experience of intra-spinal tumor.Methods To retrospective analysis of the clinical data of 24 cases with intra-spinal tumor in Shanxi Provincial People's Hospital from January 2008 to September 2015.The diagnosis of the intra-spinal tumor was confirmed by preoperative MRI examination.Intraoperative application of endoscopic surgery in the resection of tumor.Longterm followed up of patient was implemented and observe the efficacy and complications after surgery.Results Postoperative symptoms of all patients have different degrees of improvement,the degrees of sensory disorder was reduce,the limb muscle strength was increased and alleviate the damages of nerve electrophysiology.No serious complications were found after operation.Of the 24 patients,17 cases were total resection of the tumor and 7 cases were subtoal resection of the tumor.Tethered cord release was operated in patients with tethered spinal cord.Conclusions Endoscopic resection assisted semi-laminectomy approach of intra-spinal tumor has slight damage to the surround structures and the impact to the anatomy of the spine was small.Endoscopic assisted semi-laminectomy approach may have siginficant clinical effect on intra-spinal tumor,and have good security.

BACKGROUND:Chronic ankle instability can cause traumatic joint disease and secondary adhesive capsulitis, and even result in permanent dysfunction.
OBJECTIVE: To explicit the forming reason of chronic ankle instability and to investigate the diagnosis and treatment methods of chronic ankle instability based on the biomechanical analysis of the ankle joint.
METHODS: PubMed and Wanfang databases were retrieved for review and basic research papers about the anatomy, biomechanics, diagnosis and treatment of chronic ankle instability published from January 1990 to December 2014. The keywords were “chronic ankle instability, anatomy of ankle joint, biomechanics, therapy, research” in English and Chinese, respectively. After screening, 40 papers were included to summarize the anatomical structure of the ankle joint, mechanism and classification, diagnostic methods, and treatment methods of chronic lateral ankle instability.
RESULTS AND CONCLUSION:Diagnostic methods of chronic ankle instability include ankle varus stress test, ankle anterior drawer test, ultrasonic test, modern imaging detection; and therapeutic methods for chronic ankle instability can be divided into conservative treatment and surgical treatment, and the surgical treatment can be subdivided into non-anatomic reconstruction and anatomical repair of the damaged ligament. Early diagnosis and effective treatment are recommended for patients with chronic ankle instability, and the treatment programs should be determined based on comprehensive analysis of ankle anatomical structure, biomechanical characteristics, pathogenesis, and diagnostic results.

Objective: To study the epidemiological of social anxiety disorder in pupils of Zhanjiang urban districts. Methods:2409 pupils from 5 elementary schools in Zhanjiang city completed the SASC. Those with a total score higher than 2 standard deviation away from the mean were interviewed. SADC was diagnosed according to the standard of CCMD-3.Results:The overall prevalence rate of SADC was 2.74 in Zhanjiang urban districts, prevalence rate for boys was 2.6, while 2.9 for girls. No sex difference was found (?~2=0.11,P=0.744). There was no significant difference among different grades (?~2=5.47,P=0.361).Conclusions:SADC exists in pupils of Zhanjiang city, we should pay more attention to this disorder for children's mental health.

Objective To investigate the feasibility of repairing surgically ablated cavernous nerves with silastic nerve tube conduit filled with nerve growth enhancing media. Methods 54 male adult Sprague-Dawley rats were randomized into 3 groups,the sham operated controls,the bilateral cavernous nerve ablation and entubulization nerve reconstruction with insulin like growth factor(IGF).1,3 and 6 months after surgery,rats models were evaluated with apomorphine test,followed by nicotinamide adenine dinucleotide phosphate (NADPH) diaphorase staining to identify NOS in penile nerve fibers of the proxiamal portion of penile shaft and penile crus. Results There was no statistically significant difference between the ablated and the entubulization nerve reconstruction groups at 1 month,however,at 3 and 6 months,Apomorphine test studies resulted in tumescence from 42% and 50% of the entubulization nerve reconstruction groups versus 0% and 0% of the ablated group,respectively (P

Objective To explore the effects of fibroblast transdifferentiation for myofibroblast (MFB) in the pathogenesis of systemic sclerosis (SSc) and to explore the antifibrotic mechanism of interferon γ (IFN-γ) in SSc.Methods The fibroblasts derived from the skin lesions of SSc patients and healthy adult controls were cultured in vitro and the MFB proportion in fibroblasts was examined by qualitative and quantitative α-smooth muscle actin (α-SMA) detection.By adding IFN-γ to the culture system with several doses,the influence on fibroblast proliferation and transdifferentiation for MFB in SSc was observed with MTT and enzyme linked immunosorbent assay (ELISA) respectively.Differences in the means of two independent samples were tested by Student' t-test.The means among multiple independent samples were com-pared by ANOVA.Results The means of positive α-SMA in SSc fibroblasts were higher than those in the controls (P＜0.01).With extended culture time,α-SMA levels of the two groups all increased gradually (P＜ 0.01 all),but there were higher α-SMA levels in SSc fibroblasts (24 h:130±19,48 h:183±21,72 h:249± 22) than those in controls (24 h:98±21,48 h:143±16,72 h:174±19) (P＜0.05 all).Although fibroblast proliferation and α-SMA levels were not influenced after adding of IFN-γ 10 U/ml (P＞0.05 all),but IFN-γ at concentration of 100 U/ml and 1000 U/ml could obviously repress fibroblast proliferation and α-SMA levels (P＜0.05 all),and 1000 U/ml had the strongest inhibiting effect at 24,48,72 h.Conclusion The fibroblasts in the skin of SSc patients have a strong potency to transdifferentiate to MFB.Early appropviate dose of IFN-γ could repress fibroblast proliferation and transdifferentiation in SSc.

Nowadays partial splenic embolization (PSE) is an important therapeutic means to treat secondary hypersplenism caused by portal hypertension. By reducing the splenic blood flow and increasing hepatic blood supply, the peripheral blood picture and the liver function indexes as well as the portal hypertension can be effectively improved. This article aims mainly to make a comprehensive review on the therapeutic effect and mechanism of PSE, its clinical efficacy, as well as the factors affecting the clinical results, and to discuss the postoperative complications, the advantages and disadvantages of different embolic materials.

Aberrant promoter methylation in special genes such as tumor suppressor genes is early eventin carcinogenesis of lung cancer. Aberrant methylation, resulting in corresponding mRNA silence or overexpression , closely relates to carcinogenesis, development, treatment response and prognosis of lung cancer and it may become a potential biomarker. Methylation of special genes may provide evidences for individual treatment of lung cancers.
