Objective To make up an exercise prescription based on traditional Chinese medical training (EP-TCMT) for patients with stable chronic obstructive pulmonary disease (COPD).Methods Eighty-five pa- tients with stable COPD were randomly divided into a control group (CG group),a traditional Chinese medicine group ( TC group) and an exercise prescription group ( EP group).The patients in the TC and EP groups were giv- en intensive training for 8 weeks.Their 6 rain walk distance (6MWD) and Borg scale scores were assessed before and after the treatment.Results The 6MWD in the TC group increased from 337.68?59.18 m to 386.14?76.71 m,while those in the EP group improved from 348.00?55.94 m to 425.17?53.22 m.The Borg scale scores in the TC group decreased from 3.14?1.94 to 2.32?1.25,while those in the EP group declined from 3.45?1.84 to 1.72?0.70.Conclusion Making up EP-TCMTs is feasible.Additional treatment was found to improve exercise tolerance and decrease dyspnea in COPD patients.Exercise therapy based on traditional Chinese methods is easy and safe.

BackgroundWhether the peeling of the inner limiting membrane (ILMP) increase the closure rate of idiopathic macular hole is still in controversy.Some ophthalmologist recommend vitrectomy combined with inner limiting membrane peeling for the treatment of idiopathic macular hole.However,the removal of ILMP is difficult because of its similar appearance to adjacent tissues.Objective This study was to investigate the efficacy of triamcinolone acetonide(TA) and indocyanine green(ICG) double staining-assisted vitrectomy combined with ILM peeling during the surgery.Methods A consecutive case- observational study was designed.The standardized vitrectomy was performed in 25 eye of 23 cases with IMH.During the vitrectomy,TA and ICG were injected into posterior pole vitreous to visualize and assist the ILM peeling.The dying effectiveness was observed,and the closure rate of macular hole,visual acuity,intraocular pressure and complications were evaluated after surgery.Written informed consent was obtained from each patient prior to operation.Results Posterior vitreous cortex and ILM were visible and the residual vitreous and cortex were removed clearly after dying of TA and ICG in all the 25 eyes.During the following-up duration of 3-8 months,the completely anatomical reattachment of the macular area was in 22 eyes ( 88.0％ ) and partially reattachment in 3 eyes( 12.0％ ).The best corrected vision was 0.07-0.60 in all of the operated eyes 2 months after surgery.Conclusions TA and ICG- assisted vitrectomy combined with ILM peeling appears to be a safe and effective method for IMH repair.

OBJECTIVETo investigate the effect of gastrodia in extracorporeal oriented inducing the differentiation of mesenchymal stem cells into neuron-like cells.

METHODSMesenchymal stem cells were separated from bone marrow of rats by wall sticking method, amplifying cultured in vitro, and differentiated into neuron-like cells by oriented induction with gastrodia. The morphology of cells was observed under light microscopy, neuro-specific enolase (NSE), nestin and glial fibrillary acidic protein (GFAP) were detected by immunocytochemistry.

RESULTSRats mesenchymal stem cells could be separated and amplified in vitro. After being induced by gastrodia for 2 hrs, most of the cells would be differentiated into meuron-like cells, revealing cytodendrite. By immunochemical staining, cells showed positive of NSE, nestin, and negative of GFAP.

CONCLUSIONRats' mesenchymal stem cells could be induced to differentiate into neuron-like cells.

OBJECTIVETo compare the differences in the clinical efficacy on Alzheimer's disease between acupuncture and medicine.

METHODSOne hundred and forty-one patients were randomized into an acupuncture group (72 cases) and a medicine group (69 cases). In the acupuncture group, the needling technique for benefiting qi, promoting blood circulation, regulating mind and improving intelligence was used at Shenting (GV 24), Baihui (GV 20), Fengchi (GB 20), Wangu (GB 12), Danzhong (CV 17), Zhangwan (CV 12), Qihai (CV 6), Xuehai (SP 10) and Zusanli (ST 36). The supplementary acupoints were selected according to the symptoms and physical signs. Acupuncture was given once a day and 6 treatments were required for a week. In the medicine group, the choline sterase inhibitor, donepezil (aricept) was prescribed for oral administration, 1 tablet (5 mg) each time, once every night. Four weeks later, the dose was increased to 2 tablets (10 mg) each time. In the two groups, the treatment of 4 weeks made one session and 4 sessions were required. The changes of scores before and after treatment in the minimum mental state examination (MMSE), the activity of daily living scale (ADL), Alzheimer's disease assessment scale-cognition (ADAS-cog) and the digit span (DS) were observed.

RESULTSAfter treatment, scores of MMSE and DS were increased as compared with those before treatment (both P < 0.05) and scores of ADL and ADAS-cog were reduced as compared with those before treatment. The score differences in MMSE, ADL, ADAS-cog and DS before and after treatment were significant in the two groups (all P < 0.01).

CONCLUSIONThe needling technique for benefiting qi, promoting blood circulation, regulating mind and improving intelligence significantly improves the overall function, cognition and activity of daily life in the patients of Alzheimer's disease and the efficacy is better than donepezil.

Effects of Cr 6+ concentration and culture time on four heavy metal removing strains,stability of these four strains removing Cr 6+,configuration changes inside or outside their cells,effects of Cr 6+ on soluble reductive sugar inside their cells,and effect of several factors on these strains had been studied,and the Cr 6+ resistance mechanisms of these strains have been discussed elementarily. The results showed that the Lethality of these strains caused by Cr 6+ was similar with one another, namely, increasing at first, then decreasing, and finally increasing again as culture time passed. Acclimatization of Candida sp. was better than Sporobolomycetaceae sp.,and the Cr 6+ resistance of Sporobolomycetaceae sp. 7-3 was the best of the four. The research also demonstrated that the metabolic activity of these strains had been influenced by Cr 6+ in a certain extent. Scanning electron microscopy,transmission electron microscopy,and atomic force microscopy observations approved that removal of Cr 6+ by Candida sp. was depended on both surface adsorption and intracellular accumulation. Effects of Cr 6+ concentration, pH, culture time, nitrogen source, carbon source and adsorption time on these strains are not the same.

Objective To describe the clinical characteristics of a patient with Gitelman syndrome,and to identify the associated SLC12A3 gene mutations.Methods A suspected case of teenager-onset Gitelman syndrome was observed in our hospital.It was further confirmed by clinical manifestations and auxiliary examination.In addition,direct sequencing for the exons of SLC12A3 gene and CLCNKB gene region was conducted to identify the probable disease-associated mutations.Results The case showed characteristics of hypokalemia,hypomagnesemia,and low level of urinary calcium and onset by age of 18.By excluding the possibilities of long-term use of thiazide diuretics,laxatives,chronic vomiting and diarrhea,he was finally diagnosed as a case of Gitelman syndrome.Furthermore,by Sanger direct sequencing,2 coding variations were identified in SLC12A3 gene region,including T304M and L488P.L488P was a new heterozygous mutation.Conclusion Detection of SLC12A3 gene mutation could facilitate the diagnosis of Gitelman syndrome and improve prognosis.
