Objective To investigate the applicative value of enhanced 3D multi-echo GRE T2*-weighted angiography(ESWAN) sequence phase values in evaluating brain gray nuclei iron content in idiopathic restless legs syndrome(RLS) patients, providing imaging basis in diagnosis and treatment of idiopathic RLS. Methods In our institute from June 2012 to September 2016,forty-five RLS patients were selected as the RLS group, and 45 healthy volunteers as the control group. ESWAN sequence was performed and serum ferritin values were obtained in all patients and volunteers. The raw data of ESWAN was postprocessed , where the phase maps were obtained. Phase analysis was performed on localized brain gray nuclei regions of interest (substantia nigra, red nucleus, dentate nucleus, thalamus, pallidum, putamen and caudate nucleus ) selected on phase maps. Differences between the 2 subject groups were evaluated using ANCOVA including age as a covariate. Results The phase values of the substantia nigra, thalamus, pallidum and putamen in the RLS group were (-0.087 ± 0.021), (-0.053 ± 0.012), (-0.161 ± 0.008), (-0.125 ± 0.019) radians , respectively. The phase values of the substantia nigra, thalamus, pallidum and putamen in the control group were (-0.127 ± 0.007), (-0.066 ± 0.007), (-0.166 ± 0.007), (-0.150 ± 0.010) radians, respectively. There were significant differences between the two groups (F=142.492, 37.988, 10.558, 60.725;P<0.05). Indicating reduced iron content in several regions of brain gray nuclei of the patients with RLS. Serum ferritin concentration between the RLS patients (157.02±95.78)μg/L and healthy controls (175.49 ± 38.65)μg/L was not significant (F=1.353,P>0.05). Conclusions Phase values can make a quantitative assessment of brain gray nuclei iron content in RLS patients, our results supported the hypothesis of reduced brain iron content in RLS patents , which may have an important role in the pathogenesis of the disorder. However, iron content change in some brain regions was not correlated with serum ferritin concentration changes.

OBJECTIVE To discuss the available methods of preventing the mattress pollution in the wards of the(hospital), and to keep the mattresses clean and dry and eliminate the hidden danger of nosocomial infection.(METHODS) The mattress protective covering is used of a new type of textile materials,and then applied into clinic.Selected 100 pieces of mattresses in the wards,divided them equally into two groups at random,the(experimental) group and the control group.After cleaning and pasteurization(surface) sampling and bacterial culturing for every mattress were undertaken.For the experimental group,spread the protective(covering) before the sheet,and for the control group,used the sheet directly.The colony number of each group was compared in the 3rd,7th,and 14th days.RESULTS The mattresses of experimental group were clean,light polluted and with less colonies,and that of the control group were heavy polluted and with more colonies.The comparisons of the total colony number and the number of every sampling point in the 3rd,7th,and 14th days of the two groups showed that there was a(significant) difference(P

?AIM: To investigate NO levels in tears and anterior chamber inflammation after phacoemulsification and intraocular lens implantation with trabeculectomy through different operative incisions.?METHODS: Totally 49 patients ( 50 eyes ) with primary acute angle - closure glaucoma and cataract were randomly divided to single-incision group and double-incision group. Both were treated by phacoemulsification and intraocular lens implantation and trabeculectomy after routine IOP-lowering drugs treatment. Preoperative and postoperative NO levels in tears were compared, and the aqueous flare and cells were examined using a laser flare-cell meter ( LFCM) .?RESULTS:Postoperative tear NO was 9. 86±0. 78μmol/L in single-incision group , it was 9. 13 ± 0. 67μmol/L in double-incision group, the differences was statistically significant(t=3. 57,P<0. 05). Postoperative aqueous flare values was 62. 42±18. 16 pc/ms in single-incision group;it was 52. 20 ± 17. 57 pc/ms in double-incision group, the differences was statistically significant(t=2. 02, P<0. 05).?CONCLUSION: The early inflammatory injury of double-incision was significantly lower than that of single -incision. It has the advantages of safety. But the surgical skill should be improved to less the injuries caused by operations.

The axon guidance molecule Slit is a secreted glucoprotein which is conserved during evolution. Slit has been implicated in regulating a variety of life activities, such as axon guidance, neuronal migration, neuronal morphological differentiation, tumor metastasis, angiogenesis and heart morphogenesis. Slit function mainly depends on the binding of its LRR-2 domain to the Ig1 domain of Roundabout (Robo) receptor, meanwhile Slit function is also mediated by a range of signaling molecules, including the heparan sulfate proteoglycans (HSPGs), GTPase-activating proteins (GAPs), tyrosine kinase Abelson, calcium ions, MicroRNA-218 and other axon guidance molecules. Several transcription factors, including Single-minded, Irx and Midline, were shown to regulate slit expression. In addition, multiple Slit isoforms exist as a consequence of alternative spliced transcripts. The research on guidance mechanism of Slit will facilitate the understanding of molecular mechanism underlying neural networks formation in the process of neural development and regeneration. Meanwhile, the studying of Slit guidance mechanism could promote the prevention and treatment of human neurological diseases and cancer metastasis.

Objective: To observe the clinical effects of Shu-acupuncture method in Nei Jing (Classic of Internal Medicine) in the treatment of shoulder and arm pain. Methods: A total of 90 patients with shoulder and arm pain were randomly divided into an observation group and a control group, 45 cases in each group. The treatment of Shu-acupuncture method in Nei Jing (Classic of Internal Medicine) was adopted in the observation group, routine acupuncture was used in the control group. The two groups were treated once every day, with 5 treatments as one course, and a 2-day rest between two courses. After 3 courses, pain was assessed by visual analog scale (VAS), and the clinical effects were compared between the two groups. Results: After the treatment, VAS scores were significantly changed in both groups (both P<0.01). The VAS score was lower in the observation group than that in the control group, with a statistical difference between the two groups (P<0.05). The total effective rate was 100% in the observation group, versus 91.1% in the control group, the difference was statistically significant (P<0.05). Conclusion: The therapeutic effect of Shu-acupuncture method in Nei Jing (Classic of Internal Medicine) is better than that of routine acupuncture in treating shoulder and arm pain.
