Objective To discuss the correlation factors of locally recurrent gastric carcinoma. Methods Clinical, pathological and periodical follow-up datas of 50 cases with locally recurrent gastric carcinoma after radical resection from 1991 to 2005 were studied retrospectively, logistic regression analysis was used to disscuse the possible correlation factors of locally recurrent gastric carcinoma. Results 66.0% of 50 cases had recurrenced within 2 years after operations; Tumor pathological stages, positive lymph nodes and radical resection extent were independent correlation factors of locally recurrent gastric carcinoma. Conclusions Most recurrences would happen within 2 years after radical resection for gastric carcinoma; Early diagnosis of reccurrent gastric carcinoma depends on periodic follow-up observation especially gastroscope; Tumor pathological stages, positive lymph nodes and radical resection extent are independent correlation factors of locally recurrent gastric carcinoma.

Objective To explore the influence of the sequential enteral nutrition(SEN) on nutritional status and prognosis in patients with acute cerebral infarction(ACI).Methods 80 ACI patients complicated with dysphagia were divided into SEN group and control group(40 cases in each group).In the first three days patients in SEN group were treated with nasal feeding short-peptide enteral nutrition[84~126(kJ/kg.d) ],than,which would be replaced with nasal feeding integral-protein enteral nutrition from the forth day.Patients in the control group were provided with ordinary fluid food by nasal feeding.Nutrition support for both groups was at last more than 10 d.In the 1 d,7 d and 14 d after treatment,data of both groups concerned with triceps skin fold(TSF),mean upper arm muscle circumference of triceps(MAMC),serum albumen(Alb),serum prealbum(PAB),heamoglobin(Hb),incidence of infectious complications,National Institutes of Health Stroke Scale(NIHSS) score and Barthel index(BI) were examined.Results Nutritional indexes(TSF,MAMC,Alb,PAB,Hb) in the SEN group were significantly higher than those in the control group(P

Objective To study clinical characteristics and diagnostic methods of lymphoma with chest invovement. Methods Twenty-five lymphoma patients with chest involvement were retrospectively analysed, they were all diagnosed in Peking University Third Hospital during 2000 to 2007. The data were collected including clinical manifestations, blood examinations, chest X-ray and CT scan, diagnostic methods and pathologic diagnosis. Results The median age of the 25 patients was 46 years old. Pyrexia(13 cases), weight loss over 10 percent in 6 months(11 cases), cough(10 cases), shortness of breath(9 cases) and painless enlargement of the peripheral lymph nodes(16 cases) were common manifestations. Erythrocyte sedimentation rate and serum lactate dehydrogenase(LDH) level were increased in 72.7% and 81% patients, respectively. The enlargement of mediastinum lymph nodes(16 cases, 64%) was the most common presentation of chest radiography, followed by pulmonary involvement(15 cases, 60%) including infiltration or pulmonary consolidation, mass, multiple nodules, diffuse ground-glass shadow, miliary lesion. There were also presentations of pleural effusion(10 cases, 40%), pericardial effusion(4 cases, 16%), chest wall mass(2 cases, 8%). Eighteen patients(72%) had at least two kinds of these presentations. The appearance of pleural effusion were yellow turbid, bloody or chyliform. Rivaha tests were all positive. The median value of plearal effusion examinations were listed as follows: specific gravity 1.031, total cells 9800×10~6/L, WBC 6.72×10~9/L, lymphocyte 86%, neutrophil 14%, protein 31.4 g/L, LDH 296 U/L,adenosine deaminase (ADA) 67.4 U/L Most patients(16 cases) were diagnosed by surgical biopsy,especialy peripheral lymph nodes biopsy (12 cases). Other patients were diagnosed by ultrasound or CT-guided biopsy (5 cases), video-assisted thoracoscopic pleural biopsy (1 case), video-mediastinoscopic mediastinum lesion biopsy(1 case), bronchial mucosa biopsy through bronchoscope(1 case), bone marrow examination(1 case). All the cases were non-Hodgkin lymphoma except one. Conclusions There was no specific clinical manifestation for lymphoma with chest involvement, but in almost half of patients there were enlargement of not only peripheral but also mediastinum lymph nodes. And there were some characteristics in serum, pleural effusion, chest X-ray and CT scan. Surgical biopsy of peripheral lymph nodes was a simple and convenient method for diagnosis. Micro-invasive biopsy had good diagnostic value for lymphoma with chest involvement, including ultrasound-or CT-guided biopsy for superficial mass, pleura, lung, liver, spleen and deep lymph nodes, video-assisted thoracoseopic and video-mediastinoscopic biopsy for pleura, lung and mediastinum lesions. But bronchial mueosa and lung biopsy during bronchoscopy had a low diagnostic rate for lymphoma.

Objective To discuss the diagnosis and surgical management of Hashimoto's disease.Methods Clinical and pathological datas of 36 cases with Hashimoto's disease from 1995 to 2006 were studied retrospectively.Results 36 cases were all confirmed to be chronic lymphocytic thyroiditis by pathological examination,6 cases,5 cases and 3 cases were apartly accompanied by nodular goiter,thyroid adenoma and thyroid cancer among them;The clinical manifestations before operation included thyroid nodules in 29 cases,thyroid seriously enlarged in 5 cases,thyroid pain in 2 cases;Great partial/subtotal thyroidectomy in one or both part were taken in 23 benign cases,or together with isthmus excision,3 malignant case received total and subtoal thyroidectomy in either part with isthmus and homolateral neck dissection.Conclusions Surgery is actively to be advised when carcinoma under suspicion,thyroid enlarged with pressure symptoms or pain,medication is ineffective.The mode of operation should be selected according to intraoperative frozen section.A long-term substitute medication of thyroxin can help to obtain a good prognosis after operation.

To use Agrobacterium rhizogenes-induced hairy roots to create new germplasm of Dianthus caryophyllus, we transformed D. caryophyllus with A. rhizogenes by leaf disc for plant regeneration from hairy roots. The white hairy roots could be induced from the basal surface of leaf explants of D. caryophyllus 12 days after inoculation with A. rhizogenes ATCC15834. The percentage of the rooting leaf explants was about 90% 21 days after inoculation. The hairy roots could grow rapidly and autonomously in liquid or solid phytohormone-free MS medium. The transformation was confirmed by PCR amplification of rol gene of Ri plasmid and silica gel thin-layer chromatography of opines from D. caryophyllus hairy roots. Hairy roots could form light green callus after cultured on MS+6-BA 1.0-3.0 mg/L + NAA 0.1-0.2 mg/L for 15 days. The optimum medium for adventitious shoots formation was MS + 6-BA 2.0 mg/L + NAA 0.02 mg/L, where the rate of adventitious shoot induction was 100% after cultured for 6 weeks. The mean number of adventitious shoot per callus was 30-40. The adventitious shoots can form roots when cultured on phytohormone-free 1/2 MS or 1/2 MS +0.5 mg/L NAA for 10 days. When the rooted plantlets transplanted in the substrate mixed with perlite sand and peat (volume ratio of 1:2), the survival rate was above 95%.

Objective To investigate the effect of electromyographic biofeedback motion sensing game on upper limb function in chil-dren with obstetric brachial plexus palsy (OBPP). Methods From March, 2013 to February, 2014, 41 children with OBPP were randomly as-signed into conventional rehabilitation group (n=21) and motion sensing game group (n=20). Both groups underwent a comprehensive course of rehabilitation, and the motion sensing game group received upper limb occupational therapy in the motion sensing game, for four weeks. They were assessed with Mallet shoulder function scale and the surface electromyogram (EMG) of the deltoid muscle when abduct-ing the shoulder before and after treatment. Results Before treatment, there was no significant difference in the Mallet scores between two groups (t=0.730, P>0.05), the scores improved after treatment in both groups (t>5.085, P<0.05), and the scores after treatment and the D-val-ue scores before and after treatment were higher in the motion sensing game group than in the conventional rehabilitation group (t>3.195, P<0.01). The integral EMG (iEMG) value, average EMG (aEMG) value and maximum EMG (EMGmax) value of the deltoid muscle improved in the motion sensing game group after treatment (t>4.420, P<0.05), however, only aEMG and iEMG improved in the conventional rehabili-tation group (t>2.282, P<0.05). All of them after treatment and the D-value were higher in the motion sensing game group than in the con-ventional rehabilitation group (t>2.155, P<0.05). Conclusion Electromyographic biofeedback motion sensing game therapy plays a role in the rehabilitation of upper limb function and muscle strength in children with OBPP.
