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 explore the prenatal diagnosis and factors influencing prognosis of congenital diaphragmatic hernia (CDH).Methods Fifty seven cases of CDH prenatally diagnosed by ultrasound in the Department of Obstetrics,Xinhua Hospital from January 1,2006 to March 31,2013 were retrospectively reviewed.Prognosis and risk factors were analyzed by ultrasound characteristics and newborn status.Statistical analysis was performed using t test,x2 test and Logistic regression.Results Forty-five (79％)of all cases were left-side CDH and the rest 12 (21％)were right-side.Fourteen fetuses were aborted.Thirty three were delivered and treated surgically,twenty-three infants survived after surgery and ten died,with an overall survival rate of 40％ (23/57).The other ten cases were delivered,but died of no treated surgically.The birth weight of the surviving neonates was heavier than that of those who died [(3 173 ±348) vs (2 846±568)g,t=2.238,P=0.033].The gcstational age at diagnosis of the aborted fetuses was younger than that of the surviving neonates [(24.0 ± 4.1) vs (30.0± 6.0) weeks,t=3.181,P=0.003].Twenty-one (91％,21/23) of the surviving neonates had a lung-to-head ratio (LHR) ≥ 1.4.A linear trend test showed a negative correlation between LHR and adverse outcome (x2=9.223,P=0.002) with a correlation coefficient-0.730 (P=0.000).LHR＜1.4 (OR=35.867,95％CI:1.861-691.341,P=0.018) and polyhydramnios (OR=9.285,95％CI:1.102-78.212,P=0.040) were risk factors for neonatal death.Right-side CDH (OR=0.158,95％CI:0.009-2.824,P=0.210),liver herniation into the thorax (OR=1.730,95％CI:0.144 20.707,P=0.665) and birth weight (OR=l.002,95％CI:0.999-1.005,P=0.135) were not risk factors.Conclusions The survival rate of CDH is still low.Gestational age on diagnosis,presence of polyhydramnios and LHR＜ 1.4 predict an adverse outcome.

Objective To determine the perinatal outcomes and its risk factors of fetuses prenatally diagnosed with the double bubble sign on ultrasound scanning.Methods The clinical data of 57 cases of fetal double bubble sign which was prenatally diagnosed by ultrasound in Xin Hua Hospital from January 1,2000 to December 31,2013 were retrospectively analyzed.The neonates survived not less than 42 days were as surviving group,and who survived lower than 42 days were as dead group.The t test,x2 test and Logistic regression were used for statistical analysis of the data.Results Of 57 fetuses with the double bubble sign,the incidence of polyhydramnios,intrauterine fetal death and associated anomalies was 88％ (50/57),4％ (2/57) and 23％ (13/57),respectively.Induced labor to terminate the pregnancy was occurred in eight cases,the other 49 cases had live births but ten neonates abandoned therapy.Thirty-nine live babies accepted surgical treatment with one dead,and the other 38 neonates survived not less than 42 days.The overall 42-day survival rate was 67％ (38/57) and the surgical survival rate was 97％ (38/39).Compared with surviving neonates,the neonates who died had lower gestational age [(35.8±3.0) vs (38.1 ± 1.9) weeks,t=2.859,P＜0.01] and birth weight [(2 229±567) vs (2 830±558) g,t=3.136,P＜0.01],and a higher incidence of prenatally diagnosed structural anomalies [3/11 vs 3％ (1/38),P＜0.05] and karyotype anomalies detected after birth [3/11 vs 3％ (1/38),P＜0.05].Logistic regression analysis showed that the fetuses with the double bubble sign and fetal growth restriction had a higher risk of complications (OR=9.893,95％CI:1.758 55.661,P=0.009).Conclusions Fetuses with double bubble sign have adverse outcome if they complicating preterm delivery,low birth weight,prenatally diagnosed structural anomalies and karyotype anomalies.
