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.

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.

BACKGROUND: Interactive metronome (IM), also known as millisecond rhythm feedback, is a rehabilitative treatment technology supported by neural plasticity theory. Cerebral immediate feedback measured in milliseconds is helpful for understanding neurocognitive mechanisms. OBJECTIVE: To overview the progress of IM applied in the rehabilitation of central nervous system. METHODS: The first author retrieved CNKI (2001-2016), Medline (1989-2016) and Imedpub (2015-2017) databases using the keywords of millisecond rhythm feedback, cognition, motor behavior in English and Chinese, respectively. Data such as theoretical researches on cerebral timing function, the mechanism underlying IM affecting cerebral timing function, and IM operation skills and application were evaluated. RESULTS AND CONCLUSION: A total of 26 eligible articles were enrolled. IM is an objective assessment and training tool that improves neural synchronization and function. IM can accelerate the speed and the efficiency of processing information of white matter tracts, and enhance the function of attention control system in order to improve the disorder of the cerebral timing. IM achieves satisfactory outcomes in the treatment of learning disabilities in children, cognitive impairment after brain injury and cerebral stroke with hemiplegia in adults. Based on the traditional rehabilitative training in the central nervous system, IM addresses critical brain timing skills, which is a promising technology in the future rehabilitation of the central nervous system.

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.

[Summary] Endometrial receptivity plays an important role in embryo implantation, and uterine fibroids is the most common benign tumor in reproductive women. In recent years, research has showed that uterine fibroids may have an effect on endometrial receptivity through the change of endometrial morphology and biochemical molecules. From the angle of effects of uterine fibroids on endometrial receptivity, this paper studied infertile patients, which may have a new idea to diagnose and treat infertility caused by uterine fibroids.

Tianshu (ST 25) is a frequently-used acupoint in acupuncture practice. It is reported that deep acupuncture has a better therapeutic effect than routine depth acupuncture. On the basis of reviewing the available literature,the present paper gives a definition about "deep acupuncture" of Tianshu (ST 25) from the anatomy angle,and makes a summary about its safety. This paper also puts forward a set of operation standards for needling Tianshu (ST 25). Moreover,the authors of the present paper also make a systematic analysis on the factors affecting the safety from the punctured depth,the diameter of the acupuncture needle and the operation technique. These methods and standards have an important significance in guiding clinical practice of acu-puncture.

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.

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.
