Objective To investigate the effect of elispheric motion on balance and walking ability of hemiplegic patients after stroke. Methods From September to December, 2016, 40 hemiplegic patients after stroke were randomly divided into control group (n=20) and ob-servation group (n=20). Both groups received conventional rehabilitation, additionally, the control group received juggling ball training, and the observation group received elispheric motion combined with juggling ball training, 20 minutes a day, six days a week for six weeks. They were assessed with the Fugl-Meyer Assessment-Sensory (FMA-S), Fugl-Meyer Assessment-Lower Extremity (FMA-LE), Berg Bal-ance Scale (BBS) and TimedUp and GoTest (TUGT) before and six weeks after training. Results After training, the scores of FMA-S, FMA-LE, BBS significantly increased (t>10.012, P<0.05) in both groups, and were higher in the observation group than in the control group (t>2.129, P<0.05);the time of TUGT significantly shortened (t>10.001, P<0.001) in both groups, and were shorter in the observation group than in the control group (t>4.669, P<0.05). Conclusion Elispheric motion can facilitate to improve the balance and walking ability of hemi-plegic patients after stroke.

Background To optimize the culture method of human retinal microvascular endothelial cells is very important for the study of retinal angiogenesis disease.Human retinal microvascular endothelial cells have been successfully cultured in previous studies,but further improvement of the culture method to harvest higher yields and purity cells is still needed.Objective This study was to design a modified method to isolate and purify human retinal microvascular endothelial cells much easily and quickly,and to compare the expression of specific markers of vascular endothelial cells,factor Ⅷ and CD31/CD34 in the cells.Methods The use of human donor eyeballs was approved by the Ethic Commission of Zhongshan Ophthalmic Center of Sun Yat-sen University.The retina tissue from healthy donor was isolated and digested by the two-step digestion method with 2％ trypsin and 0.133％ collagenase Ⅳ.Human retinal microvascular endothelial cells were collected and plated in 60 mm dishes coated by 0.1％ fibronectin and cultured in endothelial cell-specialized medium supplemented with 10％ fetal bovine serum,0.3 mg/L β-endothelial cell growth factor (ECGF) and 100 ng/L sodium heparin.During the culturing,the growth situation of the cells was monitored by morphological observation,and immunohistochemical staining was performed to probe vascular endothelial cell-specific membrane protein CD31,CD34 and factor Ⅷ for identification of the cell purity.Results Human retinal microvascular endothelial cells were isolated successfully from the retina by the twostep digestion method.The primary cultured cells adhered to well 72 hours later and achieved confluence with the typical cobblestone appearance 9 to 10 days after cultured.The cells exhibited the blue nuclei and reddish cytoplasm by regular haematoxylin and eosin stain and showed a strong positive response for CD31,CD34 and factor Ⅷ by immunohistochemistry.The positive dye of CD31 and CD34 was lower than Ⅷ factor in both endothelial cells.Conclusions Modified culture method of human retinal microvascular endothelial cells can improve cell culture result and purify target cells.

Objective To choose proper proton magnetic resonance spectroscopy(~1XH-MRS) parameters to fit for practical femoral marrow cavity and to produce short-timed,well-repeated and excellent ~1H-MRS images.Methods The tentative study of ~1H-MRS on the normal femoral bone marrow in 26 volunteers was performed with a 1.5 T MR after the informed consent.The single-voxel spectroscopy and stimulated echo acquisition mode were used for ~1H-MRS collection.~1H-MRS parameters for 12 volunteers were 128 acquisitions,1 cm?1 cm?1 cm volume of interest(VOI)size and repeatedly 2—3 times within the same location.~1H-MRS parameters for another:14 volunteers were different numbers of acquisition (128 and 256 times,respectively)and different VOI sizes(2 cm?2 cm?2 cm and 1 cm?1 cm?1 cm, respectively).Results For ~1H-MRS with 1 cm?1 cm?1 cm size of VOI and 128 times of acquisition with the full width haft max of water≤8—12 Hz,the base-line was steady and the signal-noise ratio was high up to 11.31.~1H-MRS was different in the different femoral locations showing the maximum peak sites at near 0.90 ppm(?10~(-6))or 1.65 ppm,but~1H-MRS within the same location was always same or similar with different VOI sizes(1 cm?1 cm?1 cm or 2 cm?2 cm?2 cm)or different numbers of acquisition(128 or 256 times).~1H-MRS acquisition time was not related with the size of VOI but with the numbers of acquisition.128 and 256 times of acquisition cost 199 s and 391 s,respectively.Conclusion With the technique of small size of VOI(1 cm?1 cm?1 cm)and decreased numbers of acquisition(128 times),it is propable to get well-repeated and excellent ~1H-MRS within less time.It is also more practical for clinics to achieve ~1H-MRS of the femoral marrow with the proper technique.

Objective To explore the pathologic changes in the brain areas corresponding to specific cognitive function and underlying mechanism of cognitive impairment in patients with epilepsy by DTI study.Methods Forty-four Patients and 20 control subjects received the test of Wechsler Adult Intelligence Scale and the Diffusion-Tensor Imaging examination.Mean diffusivity (MD) and fractional anisotropy (FA) in the normal appearing white matter of interested area were measured.T test was employed to compare the MD and FA between patients and healthy controls,patients with normal and impaired FIQ respectively.The relationships between FIQ and DTI value were analyzed by Bivariate correlations.Results VIQ (100.52?17.63),PIQ (95.10?16.72) and FIQ (98.19?17.76) of the patients with epilepsy were significantly lower than those of health controls (VIQ,PIQ and FIQ were 109.77?13.54,108.11? 12.17 and 109.81?10.57,respectively).Significant reduction of FA in both side of posterior limb of internal capsule (P

Objective To investigate a new method of improving design of the skin flap pedicled with descending hranch of lateral femoral circumflex artery,in order to increase the accuracy of preoperative Doppler location.Methods Six fresh cadavers underwent a whole body,intra-arterial injection of a lead ox- ide and gelatine preparation.Observe the perforators of anterolateral thigh by dissection,measured their diam- eter;course,branches and location for there were showed up by angiography and photography.A specific pro- gram,3D-doctor,was used for the detection of the regions of interest in angisome and its 3D-reconstructive.In addition to the average area supplied by a single perforator within that territory was calculated from digital an- giograms using Scion Image.Results There were 16 perforators that the diameter≥0.5 ram,20%were septocutaneous,80%were musculocutaneous.Their average external diameter was 0.8 ram.The average ped- icle length from the deep fascia was(3.15?1.43)ram;the perforators from descending branch of lateral cir- cumflex femoral artery walk length average about 2.63 cm in superficial fascia.The area of each perforator supplied blood was average 45.61 cm~2.Conclusion Modified lead oxid-gelatine technique provides high quality angiograms for the study of cutaneous artery and perforator falp.Based on our data,the maximum di- mension of the anterolateral thigh perforator flap can be 30 cm?20 cm in with only a single dominant perfora- tor.The perforator flaps deviced by perforators from the anterolateral thigh are transplanted to the lower limbs and the other part of the body.

BackgroundHuman retinal gliocytes play an important role in proliferative diseases,which are the basis of in vitro studies.Researchers have cultured human retinal gliocytes in the past.In our study,we found that the cells we cultured presented a unique shape different from those by other researchers.ObjectiveThis study was to design to produce a new culture and purification method for retinal gliocyte in vitro.Methods Retinal tissue was isolated from human eyeballs and digested using the two-step digestion method (2％ pancreatin and 0.133％collagenase Ⅵ) to harvest the retinal glio cytes.The cells were collected and cultured in endothelial cell-targeted nutrient culture containing 10％ fetal calf serum and supplemented with β-endothelial cell growth factor (ECGF) and sodium heparin,and the culture dishes were coated with fibronectin(FN) to promote the attachment of retinal gliocyte.During the culturing process,the gliocytes were identified by the observation of morphological characteristic and regular histological examination.The identification of the cells also was performed by immunochemistry targeting glial fibrillary acidic protein (GFAP),Vimentin,neuron specific enolase ( NSE ),S-100,CD34,and Ⅷ factor.Results Retinal gliocytes were isolated successfully from the human retina by the two-step digestion method.Primary cultured cells attached after 72 hours and achieved confluency between day 9 and 10 that were aligned petaliform in shape.Regular histological examination after H&E staining showed blue cell nuclei and light red cytoplasm.The target cells presented with strong responses for GFAP and Vimentin and no response for NSE,S-100,CD34 and Ⅷ factor.ConclusionsLarge amount of purified human retinal gliocytes can be obtained by two-step digestion and cultured in endothelial cells-targeted culture medium supplemented with β-ECGF and sodium heparin in plates coated with FN.The cultured cells expressed markers for retinal gliocytes.However,specific features of these cells remain to be further elucidated.

OBJECTIVETo study the clinical characteristics of urticaria in children versus adults, and to provide reference for the etiological analysis, disease evaluation, and treatment of urticaria in children.

METHODSThe clinical data of 2 411 patients with urticaria who visited the Department of Dermatology at Xiangya Hospital of Central South University from January 2013 to May 2017 were collected to study their socio-demographic characteristics. The clinical characteristics of urticaria were compared between the 68 children and 672 adults of the 740 patients with complete follow-up data.

RESULTSAmong the 411 pediatric patients, 314 (76.4%) had acute urticaria; among the 2 000 adult patients, 896 (44.8%) had chronic spontaneous urticaria. The causes of acute urticaria in children included infection (41%, 16/39). The accompanying symptoms of acute urticaria in children mainly included abdominal pain and diarrhea (44%, 17/39), while those in adults mainly included chest distress and shortness of breath (32%, 11/34). Compared with the adult patients, the pediatric patients had significantly lower chronic urticaria activity scores before and after treatment (P<0.05), a significantly higher rate of response to second-generation antihistamines (82.1% vs 62.2%; P<0.05), and a significantly higher proportion of individuals with a personal and family history of urticaria (P<0.05).

CONCLUSIONSAcute urticaria is more commonly seen than chronic urticaria in children with urticaria, and the main accompanying symptoms are abdominal pain and diarrhea, which are different from adults with urticaria. Chronic urticaria has a better treatment outcome in children than in adults. The most frequently seen cause of acute urticaria is infection in children. Atopic children may be susceptible to urticaria.

OBJECTIVETo investigate the cellular effects of Pien Tze Huang (PZH) in the HT-29 human colon carcinoma cell line.

METHODSThe viability of HT-29 cells was determined by MTT assay. A fluorescence-activated cell sorting (FACS) analysis with annexin-V/propidium iodide (PI) and JC-1 staining were performed to determine cell apoptosis and the loss of mitochondrial membrane potential, respectively. Activation of caspase 3 was evaluated by a colorimetric assay. The mRNA expression levels of Bcl-2 and Bax were measured by reverse transcription polymerase chain reaction (RT-PCR).

RESULTSPZH, in a dose- and time-dependent manner, reduced viability and induced apoptosis of HT-29 cells. Moreover, PZH treatment resulted in the collapse of the mitochondrial membrane potential, activation of caspase 3, and an increase in the Bax/Bcl-2 ratio.

CONCLUSIONPZH inhibits the growth of HT-29 cells by inducing cancer cell apoptosis via regulation of the Bcl-2 family and activation of caspase 3, which may, in part, explain its anticancer activity.
