Objective To explore the effect of electromyogram-triggered neuromusclar stimulation (ETNS) on motor function of upper limbs of stroke patients. Methods 45 stroke patients from July, 2011 to December, 2012 in China Rehabilitation Research Center were randomly divided into control group (n=15), neuromuscular electrical stimulation (NMES) group (n=15) and ETNS group (n=15). 3 groups were given routine medication and rehabilitation treatment. They were assessed with the largest surface electromyography (sEMG), Simple Test for Evaluating Hand Function (STEF), and modified Barthel Index before and after treatment. Results After treatment, the range of sEMG of extension carpi radialis and STEF improved in three groups (P<0.05). NMES group and ETNS group were better than the control group (P<0.05), and ETNS group was better than NMES group (P<0.05). The scores of modified Barthel Index rose (P<0.05), NMES group and ETNS group were better than the control group (P<0.05). Conclusion Both NMES and ETNS can improve the motor recovery of upper limbs after stroke, and ETNS is more effective.

Objective:we aim to determine the relationship between Cell sarcoma (c-Src) expression in patients with EOC and the disease phenotype.Methods:c-Src expression was evaluated using Western blotting analysis in 21 ovarian carcinomas and 4 normal ovarian tissues.Immunohistochemistry was used to evaluate c-Src expression in 134 ovarian carcinomas and 26 normal ovarian tissues.The association between c-Src expression and clinically pathologic characteristics were also assessed in these patients.Results:Our results indicated elevated c-Src protein in EOCs compared with that in normal tissues.The overexpression of c-Src was significantly associated with aggressive features,such as advanced disease stage,poor histological grade,lymph node metastasis,and tumor recurrence (P＜0.05).In addition,the overexpression ofc-Src is significantly associated with EOCs' prognosis.Conclusion:c-Src overexpression was significantly associated with the malignant biological behavior of tumor,suggesting c-Src as a potential preventive target in these patients.

50 days),whereas third party skin grafts were vigorously rejected.Conclusion Blockade of CD28-B7 and CD40-CD40 ligand interactions resulted in long-term allograft survival and donor-specific tolerance in mouse cardiac transplantation without chronic rejection.

To determine the residue of 14 sulfonamides in milk, a high performance liquid chromatography-tandem mass spectrometry ( HPLC-MS/MS ) method with on-line soild phase extraction ( SPE ) in cation exchange mode was established. 5 g of milk was extracted with 15 mL acetonitrile. Then the extraction was evaporated by 50 ℃ nitrogen and dissolved by 1. 00 mL 0. 2% formic acid. The dissolution was enriched and purified by MS/MS cation exchange on-line SPE column on a double ternary liquid chromatography, and eluted by the mixed solution of 2% ammonia methanol and 0. 2% formic acid (50:50, V/V). The compounds were separated by an octadecyl silica bonded column and determined by the tandem mass spectrometry. The results showed that the linearity of 14 sulfonamides was good in the range of 0 . 1–10 μg/kg ( r≥0 . 9995 ) .
The LOD of the method was 0. 05 μg/kg, while the LOQ was 0. 1 μg/kg. The recoveries of the 14 sulfonamides were in the range of 60 %-90 %, while the inter-batch and intra-batch RSDs were all lower than 10%. The method was proved to be more convenient, economical and stable than the traditional SPE column method.

The hypoxanthine-guanine phosphoribosyl transferase (HGPRT) gene mutation is responsible for gouty arthritis, kidney stone, and Lesch-Nyhan Syndrome (LNS). It has been reported that the expression of HGPRT is decreased or even absent in these diseases. Rabbits are an ideal model for studying the pathology of these diseases. Therefore, the development of an HGPRT-knockdown rabbit model will be highly beneficial m such studies. Stable HGPRT-knoekdown transgenie fibroblast lines were generated by transfecting rabbit fibroblasts with RNA interference (RNAi) plasmids. Polymerase chain reaction (PCR) analyses indicated that the average positive rate was 83.3%. The mRNA and protein levels of HGPRT in the transgenic fibroblast lines were significantly lower than that in the control. Transgenic rabbit blastocysts were derived after performing nuclear transfer. The results show that RNAi can be used to stably knock down expression of the HGPRT in rabbit fibroblasts and further improvements in related technologies will facilitate the use of this method for the generation of HGPRT-knockdown rabbits.

OBJECTIVETo investigate the therapeutic results after various kinds of partial laryngectomy for patients with glottic carcinoma of the larynx.

METHODSFrom January 1980 to Mar 2004, 98 patients with glottic carcinoma of the larynx were treated by various kinds of partial laryngectomy. The types of operation varied according to stage of the lesion: vertical or frontovertical partial laryngectomy for T1b, T2 and T1a with invasion of anterior commissura, Tuker's operation or supracricoid partial laryngectomy for T1b, T2 or those with invasion of over half of contralateral cord, and extended vertical partial laryngectomy with resection of arytenoids for T3, or with invasion of ipsilateral arytenoids cartilage without involving postcricoid mucosa or posterior commissura. Totally, vertical partial laryngectomy was carried out for 76 patients, extended vertical partial laryngectomy for 7, supracricoid partial laryngectomy for 3 and Tucker's operation for 12. One stage unilateral neck dissection was performed in 5 patients and postoperative radio-therapy was supplemented to 5 (dose 60 Gy). For laryngeal function restoration, pectoro-hyomyo-flap and cricohyoidoepi glotopexy procedures were also performed for some patients. The clinical data of these patients were retrospectively analyzed.

RESULTSThe 3- and 5-year survival rate was 86.5% (64/74) and 81.7% (49/60), respectively. The total decannulation rate was 94.9% (93/98), though fifteen patients had had symptoms of aspiration. Swallowing function of all patients recovered to the normal level. The phonation of all patients was restored to various degrees and they were able to communicate socially.

CONCLUSIONThe 3- and 5-year survival rates of partial laryngectomy for patients with glottic carcinoma of the larynx are comparable to the results achieved by total laryngectomy, but the quality of life of the patents much better. Complete resection of the tumor and simultaneous preservation of respiratory and vocal function whenever possible by partial laryngectomy is very important for improving patients' life quality. With a suitable size and good blood supply, the sternohyoid muscle flap of unipedical and half-thickness instead of whole thickness is ideal in the reconstruction of laryngeal defect after vertical partial laryngectomy.

Objective To compare the clinical efficacies regarding femoral artery or radial artery approaches on coronary artery interventional therapies.Methods 360 patients were randomly divided into intervention group via femoral artery (TFI) or transradial coronary intervention (TRI) group.Postoperative observation on the two said groups of patients with vascular lesion characteristics,feasibility factors ( success rate of interventional therapy puncture,time of operation and hospitalization)and complications,were made.Results There were no significant differences between the two groups on the characteristics of vascular lesion (P＞0.05).Success rates of the two groups were 97.78％ and 96.67％ respectively.The differences on success rate,time of operation were not statistically significant (P＞0.05) while the average time of puncture,the mean duration of hospitalization and the rates of complications were significantly different ( P＜ 0.05 ).Conclusion The two methods under comparison had similar success rate and feasibility.However,the complications related to radial artery interventional therapy were much less than the femoral artery interventional therapy.As having better safety,radial artery interventional therapv seemed to have applicable value on clinical oractice.

It is generally accepted that the inhibition of apoptosis is one of the mechanism of drug resistance to tumor. Members of the bcl-2 gene family are the most important regulators in apoptosis. The purpose of this study is to evaluate the value of expression of bcl-2 and bax gene in predicting the prognosis of acute leukemia patients, and to explore the relationship between bcl-2 and bax expression and drug resistance. Seventy patients with acute leukemia entered this study. Expressions of bcl-2, bax and mdr-1 gene were measured by RT-PCR method and FCM. The result showed that: bcl-2 had been widely detected in specimens of blood or bone marrow from acute leukemia patients, the expression levels were much higher than those in normal control (1.46 vs 0.71, P < 0.05), bax expression levels and bax/bcl-2 ratio in patients had no significant difference with the control. No relationships were found between the expression levels of bcl-2 and bax and AL patients' age, sex, platelet counts, hemoglobin levels, percentage of marrow blasts, FAB classification, and S + G(2)M%. Both Bcl-2 protein expression (34.6% vs 69.2%, P < 0.03) and bax/bcl-2 mRNA ratio (37.1% vs 82.9%, P < 0.01) were associated with response to therapy and CR rate, bax/bcl-2 ratio also influences the overall survival time. There was no relationship between bcl-2 and bax expression levels and mdr-1 expression levels.
