Objective To detect the expression of selenium binding protein 1 ( SBP1 ) in gastric cancer cell line SGC7901, BGC823, normal gastric epithelial cell line GES-1, gastric cancer tissues and normal gastric tissues, explore the relationship between SBP1 and pathologic features, and discuss the feasibility of SBP1 as an diagnostic marker of gastric cancer. Methods The clinical data of 135 patients with gastric cancer who were admitted to Zhongnan Hospital of Wuhan University from 2006 to 2007 were retrospectively analyzed. The expression of SBP1 in the gastric cancer tissues and 16 cases of normal gastric tissues were detected by immunohistochemistry. The mRNA and protein expressions of SBP1 of SGC7901, BGC823 and GES-1 were determined by Western blot and RT-PCR. All data were analyzed by using chi-square test and one-way analysis of variance.Results The mRNA expressions of SBP1 in BGC823 and SGC7091 were 0. 120 ± 0. 020 and 0. 133 ± 0. 015,respectively, which were significantly lower than 0. 907 ± 0. 015 in GES-1 ( F = 2106. 462, P ＜ 0.05 ). The protein expression of SBP1 in BGC823 and SGC7901 were 0.253 ±0.015 and 0.273 ±0.015 ,respectively, which were significantly lower than 0.877 ±0.025 in GES-1 ( F = 1026. 758, P ＜0.05 ). A strong positive reaction of SBP1 was observed in 3 cases of gastric cancer tissues and 16 cases of normal gastric tissues. The decrease of the protein expression of SBP1 was correlated with clinical stages of the patients ( x2 = 12. 629, P ＜ 0.05 ), rather than the sexes, ages, tumor histological types, tumor differentiation, infiltration depths and lymph node metastasis (x2 =2. 142, 0.860, 1.838, 5.001,4.858, 1.994, P＞0. 05). Conclusions The decrease of SBP1 expression could be used as a marker in diagnosing gastric cancer. Down-regulation of SBP1 expression may play an important role in the genesis and prognosis of gastric cancer.

Objective To observe the toxic effects of mercuric chloride (HgCl2) on the productive function of male mice with lower dosage exposune. Methods 4 week-aged male ICR mice were randomly divided into 3 exposure groups, and control group. The 3 exposure groups were treated with doses of 0.25, 0.50, 1.00 mg/kg HgCl2 by peritoneal injection respectively, one time per 3 days, 10 times in total. After exposure to HgCl2 for 50 days, the male mice were mated with female mice non-exposed to HgCl2 in a ratio 1∶2. The pregnant rate, number of pups whelped per group, body weight of offspring, testis index, sperm count, sperm motility rate, abnormal sperm rate were observed. Results The pregnant rates were 100%, 100%, 83.33% and 66.67% for control group, 0.25 mg/kg group, 0.50 mg/kg group and 1.00 mg/kg group respectively during 1-week conception, 100%, 100%, 83.33% and 75% for above corresponding groups respectively during 3-weeks conception respectively. The pregnant rate of 1.00 mg/kg group was significantly lower than that of control during 1-week conception (P

OBJECTIVE Approach the cause of esophageal perforation and the analysis of diagnosis, therapy and its outcome in this disease. METHODS We retrospectively review 11 patients of esophageal perforation between1997 and 2004 in our department. There were 9 cases were taken out foreign bodies from their esophageal, another 2 cases haven't been found any foreignbodies and 1 of 2 was caused by iatrogenic reasons. Perforation occurred in the cervical esophagus was 4, and in the thoracic esophagus was 7. Their symptoms were dysphagia or pain, retrosternal-pain, dyspnea, subcutaneous emphysema, fever, hematemesis or melena. RESULTS 7/11 cases visited the clinic during 24 hours after foreign-body occured, 4/11 cases visited after 24 hours and the last visited clinic on 27th day late. Dysphagia was the most common presenting symptom specially with pain in eating, noted in 9 cases (81.8 %); retrosternal-pain and fever were noted in 8 cases (72.7 %), subcutaneous emphysema in 5 (45.5 %), dyspnea in 2 (18.2 %), hematemesis and melena.in 1 (9.1 %). 5 cases were died and the common mortality was 45.45 % (5/11). The mortality in primary repair with surgery treatment was 66.7 % (2/3); the mortality in conservative management was 37.5 % (3/8). The mortality of the perforation in cervical esophagus was 25 % (1/4), in thoracic esophagus was 57.14 % (4/7). The mortality of the visit time in 24 hours was 28.57 % (2/7),and out of 24 hour was 75% (3/4). CONCLUSION Sophageal perforation is usually caused by foreign body or iatrogenic in ENT-Head&Neck surgery. The esophageal perforation will been cured that decided in early visiting, taking away of foreign-boby, the right choice of antibiotic, nutritional support, primary healthy statement of esophagus. We regard that should perform non-operational conservative therapy in the patients who resulted in esophageal perforation except abscess or remain causing by foreign body. And the high risks in mortality of the repairing in surgery should been noticed.

Objective To investigate the clinical effect of interventional therapy in the treatment of acute iliofemoral venous thrombosis.Methods A total of 20 patients with acute iliofemoral venous thrombosis was treated by interventional therapy from February 2004 to April 2006.Under the guidance of ultrasonography,intravenous thrombolysis through the popliteal vein combined with iliac vein stenting was employed.The venous patency was assessed with angiography.Results The catheter-based thrombolysis through the ipsilateral popliteal vein was effective for all the patients.Balloon dilatation angioplasty combined with endovascular stenting was applied in 15 patients,while balloon dilatation angioplasty alone was utilized in other 5 patients.The implantation of a temporary cava filter was required in 10 patients.After intravenous thrombolysis through the popliteal vein,the recanalization rate was 30%～90%(mean,55%) in the iliac vein and 40%～80%(mean,65%) in the femoral vein.Postoperative hematuria was encountered in 1 patient.No symptomatic embolism of pulmonary artery was seen.Postoperatively,clinical symptoms on the effected limb significantly subsided or completely disappeared.The hospitalization expenditure was 52 000～81 000 yuan(mean,74 000 yuan).Follow-up observations for 1～24 months(mean,12 months) were carried out in the 20 patients.The patency rate was 100%(15/15) in 15 patients receiving iliac vein stenting.Out of 5 patients with balloon dilatation,the iliac vein was completely obstructed in 2 patients and was recanalized by 10%～20% in 3 patients.Conclusions Catheter-based thrombolysis through the popliteal vein combined with endovascular stenting is an effective therapeutic strategy for acute iliofemoral venous thrombosis,but it is very expensive.

Objective:To investigate the impact of alanyl-glutamine(Ala-Gln) on outcome in radiation enteritis rats.Methods: Male SD rats(n=70)were separated randomly into four groups: control group(n=10),AR+pseudosurgery group(n=20),AR+TPN group(n=20) and AR+TPN+Ala-Gln group(n=20).Rats were observed for mortality,changs of body weight,villous hight and area,the bcteriral translocation(BT)in mesenteric lymph nodes(MLNs),liver,spleen and peritoneal cavity.Serum TNF-? and sIL-2R level were determined by sandwich ELISA.Results: When Ala-Gln was administered in radiation enteritis rat,the mortality,body weight loss and bacterial translocation were decreaded,the villous hight and area was increased and the TNF-? and sIL-2R levels were reduced.Conclusion: Parenteral Ala-Gln nutrition can improves the results of radiation enteritis rats.

OBJECTIVE:To discuss the risk factors for lung infection of CRAb in ICU,and to provide reference for clinical di-agnosis and treatment. METHODS:The univariate analysis and multivariate Logistic regression analysis were conducted with the method of case-control study,in which the clinical data of 105 cases of lung infection of CRAb in ICU were collected from our hospital during Jun. 2012 to Jun. 2014,with the 81 cases of CRAb and 24 cases of CSAb. RESULTS:The univariate analysis showed that those factors were significantly correlated with lung infection of CRAb in ICU,such as ICU hospitalization days be-fore isolation of Ab,total stay in ICU,respiratory failure,hypoproteinemia,mechanical ventilation,mechanical ventilation days, the application of carbapenem antimicrobial agents and combined use of antimicrobial agents within 15 days before isolation of Ab, abnormal C-reactive protein detection,abnormal procalcitonin detection. The multivariate analysis showed that ICU hospitalization days before isolation of Ab,the application of carbapenem antimicrobial agents within 15 days before isolation of Ab,mechanical ventilation,hypoproteinemia were the independent risk factors of CRAb. CONCLUSIONS:Based on risk factors,the measures should be taken for high-risk patients as soon as possible in ICU to prevent and treat lung infection of CRAb.
