Restless legs syndrome is one of the common complications of maintenance hemodialysis. At present, there is no exact efficacy of Western medicine treatment. Deficiency of spleen and kidney, and deficiency of qi and blood are the TCM pathogenesis for this syndrome. LI Dong-yuan's theory of Yin Fire based on deficiency of spleen and stomach, down in the kidney, and clear Yang not rising. The creation of Shengyang Sanhuo Decoction can enrich Yang Dao and scatter Yin Fire. Yang three needles can warm yang, tonify qi and invigorate the kidney, and has a yang from yin therapeutic effect. Syndrome differentiation of medicine and acupuncture is consistent with the pathogenesis of restless legs syndrome in hemodialysis patients. It can provide new ideas and new targets for optimization of TCM treatment, and provide low cost, simple and effective treatment mode for primary hospitals.

Anandamide (N-arachidonoylethanolamide), an arachidonic acid derivative, is an endogenous ligand for cannabinoid receptors, which are m embers of the G protein (Gi)-coupled receptors family. Ananamide is mainly foun d in central nervous system, immune system and uterus etc and mimics most of the effects of (－)Δ9-tetrahydrocannabinoid ［(－)Δ9-THC］, a psyco active derivative of marijuana. Fatty-acid amide hydrolase (FAAH), which is inv olved in hydrolyzing anandamide to arachidonic acid and ethanolamide, may quickl y regulate level of anandamide in vivo.

This study analyzed the average annual growth rate of Youth Science Fund projects and the National Science Fund for Distinguished Young Scholar in 11 colleges and universities.Those projects were funded by the department of life science of National Natural Science Foundation of China (NSFC) in 2001- 2009.The average annual growth rate was calculated by Algebraic average method.The results showed that:① the average annual growth rate of Youth Science Fund project rose or dropped with the rise or drop of average annual growth rate of Science Fund Project.② the rapid growth of Youth Science Fund projects may enhance the ability of colleges and universities to gain National Science Fund for Distinguished Young Scholar.③ the capability of colleges and universities to gain life science project funded by NSFC is not balanced among different regions,and this gap is widening,and ④ to narrow the gap between disciplines,greater effort is needed to train outstanding young scholars.

Objective:To investigate the protection of acupuncture on damaged myelin sheath from the poinr of view of neurological functional recovery and morphological changes of the myelin sheath.Methods:Eighty-nine adult male Sprague-Dawley rats were randomly allocated to normal (n=5),sham-operation (n=21),model (n=21),early acupuncture (n=21) and late acupancture (n=21) groups.A model of middle cerebral artery occlusion was induced by the intraluminal filament method.Acupuncture was performed at different time points after ischemia.Neurological function and morphological changes of the myelin sheath of ischemic focus were observed by using the methods of neurological deficit scores and Pal-Weigert's myelin staining.Results:Neurological deficit scores at 2.5 hours after the procedure in the model group increased significantly (P＜0.05).qhe scores decreased somewhat as the time elapsed.The internal capsule had obvious demyelination and recovered slowly.Neurological deficit scores in rats at each time point decreased faster in the acupuncture group compared with the model group,and they decreased significantly at day 3 (P＜0.05);the extent of demyelination was significantly alleviated.Neurological deficit scores decreased faster in the early acupuncture group compared with the late acupuncture group (P＜0.05);and demyelination in the early acupuncture group seemed milder at day one.Conclusions:Early acupuncture is beneficial to remyelination and neurological functional recovery after cerebral ischemia.

0.05). Conclusion: The measurements of molar distal movement on model are smilar to those on cephalometric radiograph.

Objective: To evaluate the effect of a new method to treat early primary crossbite . Methods: 20 cases (2.8～6.5 years old ) with anterior crossbite were treated by bonding appliance combined with protracting mask. Cephalometric radiographs were taken and analyzed before and after treatment. Results: On average,in all the 20 cases the maxilla were moved 2.06 mm forward ,mandibular were turned 2.45?downward and backward ,the anterior crossbite was corrected and the face profile was improved satisfactorily.The treatment was conducted for 1.7 months on average. Conclusion: Using bonding appliance combined with protracting mask to treat early primary crossbite can achieve good effects for young children .

Objective To investigate the new and non-surgical treatment of hemangioma.Methods Totally 53 patients with hemangioma were treated with Nd: YAG laser in our department in recent years. Surface irradiation was used for 6 cases with port wine stain and interstitial irradiation for 14 cases with carvernous hemangioma and the two methods for 9 cases with strawberry hemangioma and 24 cases with mixed hemangioma.Results all the 53 patients were followed-up for 3 years.lesions of 48 cases were removed completely, and lesions of 3 cases were significantly controlled. Only 2 cases were failed in this treatment.Conclusion Resection of maxillofacial hemangioma in children by ND:YAAG laser is a reliable and effective method.

BACKGROUND:Bone marrow mesenchymal stem cel s have a close relationship with tumor occurrence and development, which are not only involved in tumor recruitment but impact the biological behavior of tumor cel s. OBJECTIVE:To investigate the effect of bone marrow mesenchymal stem cel s on the biological behavior prostate cancer cel line. METHODS:Human bone marrow mesenchymal stem cel s from healthy adults were col ected and cultured in vitro. Cel morphology and cel markers were observed. Using the Transwel technique, human dermal fibroblasts HDF-a were co-cultured with human prostate carcinoma DU145 cel s in positive control group, wild-type prostate carcinoma DU145 cel s cultured alone in negative control group, and bone marrow mesenchymal stem cel s co-cultured with human prostate carcinoma DU145 cel s in experimental group. Flow cytometry assay was used to detect the cel cycle of prostate carcinoma DU145 cel s, soft agar colony formation assay performed to detect cel proliferative ability, and crystal violet staining used to observe DU145 cel migration at 3 days after culture. RESULTS AND CONCLUSION:Compared with the negative control group, cel proportion at G 2/M+S phase, number of transmembrane cel s and colony counting were significantly decreased in the experimental group. These findings indicate that bone marrow mesenchymal stem cel s may inhibit the proliferation and invasion of prostate carcinoma DU145 cel s by shortening the G 2/M+S phase, thereby providing a new insight into the treatment of human prostate cancer.

Objective To investigate the effects of nutritional risk on incidence of pressure ulcer in hospitalized elderly patients,and to provide a basis for medical staff to carry out effective preventive measures.Methods Nutritional Risk Screening 2002 (NRS-2002) and nutrition index were applied in 150 elderly patients in the department of neurology for screening and evaluation of nutritional risk.Then the effect of nutritional risk on incidence of pressure ulcer in elderly patients was analyzed.Results 86 cases with nutritional risk and 64 cases without nutritional risk were found.The incidence of pressure ulcer was 16.67％ and 42.67％ respectively.The comparison was made among hemoglobin,serum albumin,pre-albu-min and total lymphocyte count,the difference was statistically significant between the two groups.The incidence of pressure ulcer in elderly patients with nutritional risk was 6.99 times higher than those without nutritional risk.Conclusions To given nutritional risk screening,active and reasonable nutritional support plan to hospitalized elderly patients can reduce the incidence of pressure ulcer.
