Objective To investigate the correlation between clinical presentations and the findings of video fluoroscopic swallowing study (VFSS)in patients with post-stroke dysphagia. Methods A total of 56 consecutive patients with post-stroke dysphagia admitted to Wenzhou Hospital of Traditional Chinese Medicine Affiliated to Zhejiang Chinese Medical University from June 2012 to May 2014 were enrolled. Four different kinds of food were selectively used to complete clinical assessment of swallowing function and VFSS respectively. The SPSS 20. 0 statistical software was used to perform univariate and multivariate Logistic regression analyses for all observed indexes of the 2 methods. Results there were significant correlations in the point correspondence relation among the clinical manifestations and VFSS in food residue in the mouth and abnormal closure of lips in the oral phase (95%CI 1. 430-101. 468;P=0. 022);poor soft palate elevation and food residue in the mouth (95%CI 1. 476-102. 033;P=0. 020);graded swallowing and piecemeal deglutition with delayed oral transit (95% CI 2. 616 -182. 897;P = 0. 004);tongue movement disorders,poor soft palate elevation and tongue dyskinesia with poor bolus formation (95%CI 1. 468-50. 795,1. 220-13. 825;P=0. 017,0. 023);food leak from the corner of mouth,dysphagia,bolus falling to the epiglottis from the base of tongue or trachea (95%CI 1. 146-125. 459,1. 657-174. 400;P=0.038,0. 017). The weakened pharyngeal reflex with weak laryngeal elevation in the pharyngeal phase (95%CI 1. 150-92. 815;P =0. 037);dysphagia and delayed swallowing with prolonged triggering of swallowing reflex (95%CI 2. 123-37. 770,1. 233-114. 176;P=0. 003,0. 032);graded swallowing,hard swallowing, choking sensation,and poor laryngeal elevation with prolonged pharyngeal transit (95%CI 1. 619-223. 316,1. 061-31. 445,2. 834 -132. 707;P =0. 019,0. 042,and 0. 003);dysphagia and the opening of cricopharyngeal muscle insufficiency (95%CI 1. 037 -24. 115;P =0. 045);weak laryngeal elevation,foreign body sensation in the throat,and choking after swallowing with food retention or residual in vallecula or pyriform sinus (95%CI 1. 046 -13. 685,1. 116 -87. 741;P =0. 043, 0.040);and coughing during swallowing and eating choking or aspiration (95%CI 0. 010-0. 921,0. 037-0. 826;P=0. 042,0. 028). Conclusion Some clinical manifestations are closely correlated with the swallowing dysfunction revealed by VFSS. With the help of this law,it may more simply and safely determine the degree and type of dysphagia in patients,and provide guidance for patients with dysphagia after stroke who can not accept VFSS in the rehabilitation treatment.

Introduction:Transcatheter arterial chemoembolization (TACE) plus thermal ablation has been widely used recently in the treatment of hepatocellular carcinoma (HCC). In this study, we aimed to compare results of the combination of TACE and percutaneous thermal ablation with those of hepatectomy in patients with HCC. Methods:The clinical data of 137 HCC patients who sequentially received TACE and computed tomography (CT)-guided percutaneous thermal ablation as an initial curative treatment (combination group) and 148 matched HCC patients who received hepatectomy (surgery group) between 2004 and 2011 were collected and analyzed. After TACE, multiphase contrast-enhanced CT was performed to identify the total number of tumors as well as lipiodol deposition in the liver. Survival was calculated by using the Kaplan-Meier method and compared by using the log-rank test. The prognostic factors were assessed with multivariate Cox proportional hazards regression analysis. Results:Of all 285 patients, 225 (79.0%) had cancerous lesions≤5 cm in diameter. In preoperative contrast-enhanced CT or magnetic resonance imaging, the number of tumors was 1–4 for each patient. The 1-, 3-, and 5-year overal survival rates were 95, 74%, and 67%in the combination group and 88, 66, and 47%in the surgery group, respectively (P=0.004);the corresponding recurrence-free survival rates for the two groups were 92, 69, and 61%and 75, 58, and 44%, respectively (P=0.001). In the multivariate analysis, treatment al ocation was an independent prognostic factor for survival. Only 60 patients in the combination group had sufficient imaging data, and 135 new lesions with lipiodol deposition were diagnosed as malignancies in 22 of 60 patients, whereas 20 new lesions were found in 11 of 148 patients in the surgery group. Conclusion:The combination of TACE and CT-guided percutaneous thermal ablation for HCC improves survival of HCC patients compared with hepatectomy.

Objective To explore the effects of extract of Gingko biloba leaves (EGb) on learning, memory and hippoeampal heine oxygenase-1 (HO-1) expression in diabetic rats.Methods The behaviors of streptozotoein-induced diabetic rats were observed by Morris water maze for learning and memory after 6 months of diabetes.The HO-1 mRNA expression and protein expression in hippocampus of diabetic rats were detected by RT- PCR and immunohistochemistry respectively.Results The escape latency time in Morris water maze of diabetic rats was prolonged markedly.HO-1 mRNA and HO-1 protein expressions in hippocampus of diabetic rats were increased (1.635?0.326 vs 0.978?0.214,7.2?1.7 vs 1.9?0.5,respectively,both P＜0.01).The escape latency times in EGb (100,50 mg/kg) treated groups were shortened.HO-1 mRNA and HO-1 protein expressions in hippocampus were decreased at the same time as compared with diabetic group (100 mg/kg:0.954?0.144,2.0?0.8;50 mg/kg:0.988?0.154,2.5?0.6,all P＜0.01).Conclusion EGb can significantly inhibit HO-1 expression in hippocampus and improve learning and memory dysfunction in diabetic rats.

Objective To investigate the clinical effect of traditional Chinese medicine(TCM)for treating HBeAg positive chron-ic hepatitis B virus(HBV)carriers with liver stagnation and spleen deficiency syndrome.Methods The patients with HBeAg and HBV DNA positive,normal serum ALT and AST for successive 3 times within 1-year follow up,complicating different degrees of symptoms were included.Among them,the patients with liver stagnation and spleen deficiency syndrome according to the TCM dif-ferentiation were selected as the treatment obj ects and treated by the prescription of soothing the liver,tonifying spleen and detoxifi-cation.The changes of clinical symptoms and HBV markers after 6-month therapy were observed and followed up for 3 months for evaluating the effect persistance.348 cases were recruited,161 cases in the control group and the other 187 cases in the treatment group.Treatment group underwent traditional Chinese medicine treatment.Results 168 cases finished the therapy with the total effective rate of 80.3%(135/168),6 cases were HBeAg negative conversion and 14 cases were HBV DNA decrease greater than or equal to 2 logarithmic grades;157 patients finished 3-month follow-up and the effective rate was 80.9%(127/157),4 cases were HBeAg negative conversion and 1 1 cases were HBV DNA decrease greater than or equal to 2 logarithmic grades.The curative effect of treatment group was higher than that of control group.Conclusion The TCM prescription of soothing the liver,tonifying spleen and detoxification has definite effect for treating HBeAg positive chronic HBV carriers with liver stagnation and spleen deficiency syndrome,the symptoms can be significantly improved.

Objective To study the effect of intensive trunk muscle training on balance and walking in pa- tients with hemiplegia caused by stroke.Methods A total of 90 stroke patients were recruited and randomly divid- ed into a treatment group(45 cases)and a control group(45 cases).All the patients were given conventional reha- bilitation training.Meanwhile,intensive trunk muscle training was also administered for those in the treatment group as well.The trunk control function,balance ability and walking ability were assessed by using the trunk control test, Berg Balance Scale and the balance subscale of the Fugl-Meyer physical performance test,and Holden's functional ambulation classification,respectively,before and after 6 weeks of training.Results It was found that all the pa- tients scored better with the trunk control test,Berg's balance scale,the balance subscale of the Fugl-Meyer physical performance test and Holden's ambulation classification after treatment,and there were significant differences between the two groups after treatment(P

Abstract?AlM:To analyze of the clinical features of acute retinal pigment epitheltis ( ARPE) .?METHODS: The clinical data of 36 ARPE patients ( 40 eyes) attending this center from January 2008 to January 2014 were reviewed retrospectively. Of them, 21 patients (58.3%) were male (male :female=1:0. 71). The mean age was 40. 92±7. 13 years old (range:17~60y). The mean best-corrected visual acuity (BCVA) was 0. 50±0. 26 with a range of 0. 3 ~ 1. 0. Thirty-two patients were unilateral cases. All the patients were examined for BCVA, funds photography, fluorescein fundus angiography ( FFA ) , optical coherence tomography ( OCT) . FFA was shown as three types: type ▏ to multiple black light or grape variety fluorescent spot; Type II for l lesions visible fluorescence leakage; Type Ⅲ lesions with choroid neovascularization ( CNV ) . OCT was the following three forms: multiple RPE lesions layer reflection intermittent, proliferation ( type ▏); pigment epithelial detachment with limitations neural epithelium ( typeII);types l and ll with CNV ( type Ⅲ) .?RESULTS: Ocular fundus showed that the lesions were multiple dark-gray spots with a dark circumscribed area at the macular or nearby in all 40 eyes. FFA showed:21 eyes were type ▏, 17 eyes were type II and 2 eyes were typeⅢ, BCVA between type ▏ and type II was statistically significant (P<0. 05), the same was between type 芋. BCVA between different cases in the same type and between type II, Ⅲ, was no statistical difference ( P>0. 05). OCT showed 21 eyes wwere type ▏, 17 eyes were type II and type Ⅲ 2 eyes. BCVA average between type▏ andIIwas statistically significant (P<0. 05). The mean BCVA was no statistically significant difference between type II and Ⅲ patients (P>0. 05).?CONCLUSlON:ARPE fundus demonstrated the multiple dark gray discrete lesions, the degree of visual impairment related with the presence of pigment epithelial barrier and lesion location. OCT and FFA characterized three types. FFA is shown asblack light orgrape variety fluorescent spot, and is the basis of diagnosis. OCT can display the lesions organization form of each layer clearly. lt plays a more and more important role in the diagnosis and differential diagnosis of ARPE.

Technological improvement for microorgnism isolation is important since isolation provides substantial materials for the exploitation of new microbial resources. In this study, a new approach, dispersion and differential cetrifugation (DDC), was applied in the isolation of acidophilic and acidoduric streptomycetes from 12 acid soil samples. Contrast with traditional method, the new approach yielded satisfying results with 2 - 20 times isolation efficiency and good selectivity. 45 representatives out of 249 streptomycetes isolates, which belonged to 12 color groups, showed morphology and cell wall type consistent with streptomycetes. The optimum pH range for their growth were between pH 4.5 - 5.5. It is proved that we succeeded in the rare-streptomycetes isolation using DDC approach.

The biochemical mechanism of degrading keratins by S.fradiae var S-221 was primarily studied.The compounds (Na_ 2 SO_ 4 , Na_ 2 SO_ 3 and sulfdryl acohol), which respecitively enhance specific activity of keratinase, activate keratinase intensively and mainly act on the disulfide bonds reductase in the keratinase, Na_ 2 SO_ 3 activates intensively both disulfide bonds reductase and polypeptide hydrolytase at 0.01 mol/L, whereas Na_ 2 S_ 2 O_ 3 , which acts on the disulfide bonds reductase, inhibits keratinase.On the condition that substrate, keratins exists, S.fradiae var S-221 is induced to produce exo-keratinase, which is a multiproteinase, containing disulfide bonds reductase, which is a key enzyme degrading keratins, then, with polypeptidic, hydrolytase, graduately hydrolyzates denatured keratins into polypeptides, oligopeptides and free amino acids, so that keratins have been decomposed completely.Sulfur in the keratins was transferred into sulfhydryl compounds, H_ 2 S and sulfates in the course of keratinolysine.

OBJECTIVETo investigate the role of EPHA2 in regulating apoptosis, proliferation and vasculogenic mimicry of osteosarcoma cells, by gene silencing through RNA interference.

METHODSEPHA2-siRNA plasmids were achieved by gene cloning. The plasmids were transfected into human osteosarcoma cells (MG63). The expression level of EPHA2 protein was measured by Western blotting. The proliferation, apoptosis and vasculogenic mimicry features of osteosarcoma MG63cells were assessed by light microscopy, MTIP assay, flow cytometry, annexin V-FITC/PI and HE staining, respectively.

RESULTSThe EPHA2-siRNA plasmid was confirmed by DNA sequencing. After treatment with Sequence-specific siRNA targeted EPHA2, the protein level of the transfected group decreased significantly. As compared to non-siRNA transfected cells, the transfected group showed lower proliferation, higher and earlier apoptosis and less osteosarcoma-generated vasculogenic mimicry.

CONCLUSIONEPHA2 gene may be involoved in apoptosis and proliferation of osteosarcoma cells, and may be necessary for vasculogenic mimicry. Down-regulation of EPHA2 expression by sequence-specific siRNA may be considered as a new option in the treatment of EPHA2 over-expressing cancer including osteosarcoma in future.
