Objective To explore a new method for assessing the walking efficiency of the paraplegic patients assisted by functional electrical stimulation (FES). Methods The measurement system based on a standard walker was developed. During FES assisted walking of the paraplegic, the real time of the upper limb support were obtained and transformed into a 3 D center of gravity (CG) motion map with a paraplegic upper body mechanical model to describe the CG motion locus. Then the FES efficiency indicated by walking balance condition was assessed objectively and quantitatively. Results In this design, the pilot study of a paraplegic patient undergoing walking training with FES showed that the force accuracy was better than 1.01%, nonlinearity was less than 0.8%, and crosstalk was less than 3.2%. Conclusion The results showed that this system may be used as 1) an evaluation index of FES assisted paraplegic walking efficiency, 2) a balance control indicator during FES assisted paraplegic walking training and 3) a feed back signal to choose an efficient FES pattern and sequence.

OBJECTIVETo observe the therapeutic effect of Xinfeng Capsule (XFC) in treating adjuvant arthritis of rats and its effect on fas, fasL and bcl-2 expression in synovial membrane.

METHODSRats were randomly divided into the normal group, the model group, the model group, the methotrexate (MTX) group, the TPT group and the XFC group. Except for the rats in the normal group, animals were modelled to adjuvant arthritis with Freund's complete adjuvant, and the latter three groups were treated with MTX, Tripterygium wilfordii polysaccharide (TPT) and XFC respectively. The arthritis index (AI), change of body weight (BW) of rats were recorded, and the expressions of fas, fasL and bcl-2 in rats' synovial membrane were determined.

RESULTSCompared with before treatment, the AI in the three treated groups was lowered significantly (P < 0.01, P < 0.05). The BW increment in the XFC group after treatment was insignificantly different to that in the normal group (P > 0.05), while it was significantly lower in the other two treated groups than that in the normal group and the XFC group (P < 0.01). Compared with the model group, fasL expression was increased in the XFC group significantly (P < 0.05), but bcl-2 expression decreased, fas expression showed insignificant difference (P > 0.05). Comparison of the three gene expressions between the three treated groups showed no significant difference (P > 0.05).

CONCLUSIONXFC could decrease AI in rats with adjuvant arthritis in the same way as MTX and TPT, it effected better in increasing BW than the latter two. The effect of XFC might be performed by its action in enhancing fasL expression, inhibiting bcl-2 expression and promoting apoptosis of proliferated synovial membranous cell so as to restrain hyperplasia of synovial membrane.

Continuously cropping obstacle restricts ginseng production and rational use of land resource severely, and autotoxicity is one of the most important factors. In our previous work, ginseng autotoxin degrading bacteria were isolated, in the present re- search, plate culturing method and traditional physiological and biochemical method were used to analyze biological indices and protective enzyme activities, in order to elucidate the mitigative effect of autotoxin degrading bacteria on autotoxicity of P. ginseng. Results indicated that, except for palmitic acid, autotoxicity of benzonic acid, diisobutyl phthalate, diisobutyl succinate, and 2,2-bis (4- hydroxyphenyl) propane on the growth of ginseng seeds was significantly alleviated after autotoxins degrading bacteria was inoculated, and which have no evident difference with control. Except for benzoic acid, enzyme activity of SOD, POD and CAT in other autotoxin degrading treatments decreased significantly. The present research showed that, microbial degradation could alleviate the autotoxicity of autotoxins on ginseng seeds effectively, and which will be helpful for the resolution of ginseng continuously cropping obstacle problem.

The paper is aimed to establish a method of residue analysis for thiamethoxam and to study its degradation dynamic and final residue and its standard of safe application of thiamethoxam on Lonicera japonica. Samples extracted with methanol by ultrasonication were purified with dichloromethane by liquid-liquid extraction and SPE column and analysed by HPLC-UV. The results showed that average rate was 84.91%-94.44% and RSD 1.74%-4.96% with addition of thiamethoxam in respectively diverse concentration, which meets inspection requirement of pesticide residue. Two kinds of dosages of thiamethoxam were treated- varying from recommended dosage (90 g x hm(-2)) to high dosage (135 g x hm(-2)), Results of two years test showed that thiamethoxam was degraded more than 90% seven days after application and the half - life period of thiamethoxam was 1.54-1.66 d. The digestion rate of thiamethoxam was fast in the L. japonica. The recommended MRL of thiamethoxam in the L. japonica is 0.1 mg x kg(-1), the dosage of 25% thiamethoxam WDG from 90-135 g x hm(-2) is sprayed less than three times a year on L. japonica and 14 days is proposed for the safety interval of the last pesticide application's and harvest's date.

Objective To study the diagnosis and treatment of blunt pancreatic injury (BPI). Methods A retrospective analysis was made on the clinical data of 58 cases of BPI admitted and treated in our hospital during 23 years. Results The positive diagnosis rate was 51.1%(23/45) for single BUS examination ,but 70.0%(21/30) for two and more BUS examimations. The positive diagnosis rate was 65.0%(26/40) for single CT scanning, but 91.3%(21/23) for two and more CT scannings. Twenty-five cases(25/37,67.6%) with BPI were determined preoperatively, and 12 cases(12/37,32.4%)during (operation).Thirty-seven cases underwent operatiom, included grade I in 10cases、grade II 13cases、grade III 9cases、 grade IV 4cases and gradeV 1case. Twenty-one cases received nonoperative treatment, included 11 grade in I,7 grade II and 3 grade III. In the entire group, 6 cases died(10.4%).The mortality in the operation group was 16.2%(6/37).There were no deaths in the nonoperative group. The main cause of death was multiorgan failure(5/6,83.3%). There were 11(19.0%)cases of pancreatic pseudocyst after treatment in the entire group, included 3(3/37,8.1%) in operation group and 8(8/21,38.1%) in nonoperation group. Conclusions The diagnosis of BPI should combine the clinical findings with repeated BUS and CT scanning. Nonoperative treatment is a good choice for BPI without main pancreatic duct injury. Operative treatment is suitable for serious BPI and those with other intra-abdominal organ jnjury.

Objective To investigate the value of partial hepatectomy and vascular resection in the treatment of hilar cholangiocarcinoma. Methods Seventy four patients with hilar cholangiocarcinoma who underwent hepatectomy of Chinese People' s Liberation Army from January 2008 through December 2011 were analyzed retrospectively.Results Of the 74 patients,33 underwent radical resection and 19 palliative resection,22 received internal or external drainage.In the radical resection group,the median survival time was 27 months,and the overall survival rate at 1,2 and 3 years were 79％,64％ and 49％.In the palliative resection group,the median survival time was 14 months and the overall survival rate at 1,2 and 3 years were 56％,25％,and 19％.In the drainage group,the median survival time was 9 months and the overall survival rate at 1,2 and 3 years were 23％,15％,0.Conclusions Hepatectomy combined with hilar vascular resection helps increase survival rate of patients in radical excision of hilar cholangiocarcinoma and Surgical resection is the most elective method for treatment of hepatic hilar cholangiocarcinoma,and the radical resection might improve the prognosis of the patients with hilar cholangiocarcinoma.

Objective To evaluate the diagnostic value of radionuclide salivagram in children with pulmonary aspiration.Methods From March 2012 to June 2015,a total of 62 patients (37 males,25 females;age range:2 d-14 years) with suspected pediatric aspiration pneumonia were enrolled in this retrospective study.All patients underwent gastroesophageal reflux (GER) imaging and(or) radionuclide salivagram.Detection rate of pulmonary aspiration by the two imaging techniques was compared with x2 test.Results Of 62 patients,14 were diagnosed as pulmonary aspiration,including 1 detected by GER imaging,and 13 detected by salivagram.The detection rate for pulmonary aspiration by radionuclide salivagram (26.0％,13/50) was significantly higher than that by GER imaging (3.1％,1/32;x2=7.211,P＜0.05).Eight of the 13 cases with pulmonary aspiration diagnosed by radionuclide salivagram underwent upper gastrointestinal radiography,and 5 cases had visible contrast agent in the airway.Conclusion Radionuclide salivagram has a higher detection rate for pulmonary aspiration compared to GER imaging,and has good concordance with the traditional upper gastrointestinal radiography.

Multidrug resistance proteins (MRP2, ABCC2) may play a role in drug resistance in epilepsy by limiting gastrointestinal absorption and brain access of antiepileptic drugs (AEDs). We sought to investigate the effects of ABCC2 polymorphisms on plasma carbamazepine (CBZ) concentrations and pharmacoresistance in Chinese patients with epilepsy. ABCC2 rs717620, rs2273697, rs3740066 polymorphisms were genotyped by polymerase chain reaction amplification followed by restriction fragment length polymorphism analysis or direct automated DNA sequencing in 80 patients treated with CBZ monotherapy. There were no differences in CBZ maintenance doses or adjusted plasma CBZ concentrations among the ABCC2 rs717620, rs2273697 and rs3740066 genotypic groups. No associations between all the studied genotypes and haplotypes involving the three SNPs of ABCC2 and CBZ resistance were observed in this patient cohort. These results suggest that ABCC2 polymorphisms may not contribute to interindividual variabilities in CBZ daily maintenance doses, plasma concentrations, and treatment efficacy.
