Objective To study the significance of Wnt5a gene expression in gastric carcinoma (GC). Methods The Wnt5a mRNA expressions in SGC7901 cell line and normal gastric mucosa GES-1 cell line were detected by RT-PCR. The Wnt5a protein expressions in 60 GC and 30 matched tumor-adjacent normal tissue samples were examined by immunohistochemistry using the streptavidin-peroxidase method.χ2 test was used to analyze Wnt5a expression on the clinical pathologic features of gastric carcinoma. Results Both Wnt5a mRNA and Wnt5a protein were significantly higher in SGC7901 cells than those in GES-1 cells. The positive rate of Wnt5a protein expression was also significantly higher in GC than that in tumor-adjacent normal tissue (P < 0.05). Positive expression of Wnt5a was associated with higher degree of regional lymph node metastasis and the later TNM stage (P < 0.05). Conclusion Higher expression of Wnt5a seems to promote invasion and metastasis of gastric cancer, and Wnt5a might play an oncogene-like role in the development of gastric carcinoma.

Objective·To analyze the clinical characteristics of decompensated cirrhosis patients with intestinal obstruction and related risk factors.Methods·Clinical data of 1 783 decompensated cirrhosis patients treated between March 2010 and March 2016 were collected.Of them,128 (7.18％) patients with intestinal obstruction were screened as the observation group and 128 patients without intestinal obstruction were randomly selected as the control group.Clinical data of two groups were retrospectively investigated,clinical characteristics were compared and analyzed,and related risk factors were analyzed with the Logistic regression analysis.Results·The clinical symptoms of decompensated cirrhosis patients with intestinal obstruction were hidden and misdiagnoses or delayed diagnoses were common.The incidences of abdominal pain,abdominal distension,vomiting,stop exhaust defecate,ascites,electrolyte disorders,fever,and spontaneous peritonitis were significantly higher in the observation group than in the control group (P ＜ 0.05).The results of univariate analysis showed that age,history of abdominal surgery,white blood cell count,serum sodium,serum potassium,neutrophil percentage,and serum albumin were risk factors for decompensated cirrhosis patients with intestinal obstruction.The results of multivariate analysis indicated that age,history of abdominal surgery,white blood cell count,serum sodium,serum potassium,neutrophil percentage,and serum albumin were independent risk factors for decompensated cirrhosis patients with intestinal obstruction.Conclusion·Decompensated cirrhosis patients with age ≥ 50 years old,a history of abdominal surgery,the abdominal cavity infection,low potassium,hyponatremia,and lower serum albumin are likely to develop the intestinal obstruction.

Objective To explore the risk factors of prehypertension and the relationship between blood pressure and atherosclerosis.Methods The data of 456 cases in the Department of General Medicine were cross-sectional analyzed,including 174 subjects with normotension and 282 with prehypertension.The information was consisted of demographic characteristics,blood pressure,blood biochemical metabolism index,brachia-ankle pulse wave velocity (baPWV),ankle-brachial index (ABI) and carotid intima media thickness (CIMT).Results Compared to normotension group,the levels of systolic pressure,diastolic pressure,pulse pressure,body mass index,fasting blood glucose,glycosylated hemoglobin,triglyceride,uric acid,and C-reactive protein in prehypertension group were significantly increased (P ＜ 0.05) ; and high-density lipoprotein cholesterol was significantly decreased (P ＜0.05) ; the body mass index(OR =1.185),triglyceride(OR =1.302),and fasting blood sugar (OR =1.690) were the independent risk factors of prehypertension ; baPWV and CIMT in prehypertension group were higher,but ABI and artery atheromatous plaque rate were not obvious changed.When baPWV or CIMT were set as the dependent variables,multiple linear regression analysis showed that systolic blood pressure(β =0.226,P =0.007),fasting blood glucose(β =0.209,P =0.018),and age(β =0.279,P =0.002) were risk factors of baPWV;systolic blood pressure(β =0.118,P =0.015),body mass index(β =0.109,P =0.001),and age(β =0.396,P =0.001) were risk factors of CIMT.Conclusions Body mass index,triglycerides,and fasting blood sugar were the independent risk factors of prehypertension.The early subclinical damage of hardening of the arteries was occurred in the prehypertension cases,and systolic blood pressure was closely related with baPWV or CIMT.

Objective To compare the individual effects of three recruitment maneuvers (RM) in children with congenital heart disease complicated by postoperation acute respiratory distress syndrome (ARDS).Methods A prospective single-blind randomized controlled trial was conducted.Thirty-two children with congenital heart disease complicated with ARDS after open-heart surgery undergoing mechanical ventilation were randomized into three groups,to whom three different RM was respectively performed,namely sustained inflation (SI),progressively increased positive end expiratory pressure (IP) and pressure control ventilation (PCV).Blood gas analysis was done every 6 hours,and the lung RM was performed if oxygenation index (OI) ≤ 300 mmHg (1 mmHg =0.133 kPa).The OI,the dynamic lung compliance (Cdyn),as well as the parameters of hemodynamics before,during and after RM for 15,30,and 60 minutes were recorded and analyzed before and after RM.Results During the treatment process,the OI was significantly increased during the process and 15,30 or 60 minutes after RM compared with that before RM,with no statistical difference among groups (F value was 1.027,0.403,0.264,0.172,0.159,and P value was 0.367,0.671,0.769,0.843,0.853).The Cdyn at all time points in each group was also significantly increased,but there was no statistical difference among groups (F value was 0.009,0.015,0.206,0.010,0.389,and P value was 0.991,0.985,0.814,0.990,0.683).In the process of RM,the heart rate (HR) and mean arterial pressure (MAP) of the children were lowered compared with those before RM [HR (bpm):131.67 ± 9.56 vs.138.93 ± 5.22 in SI group,133.27 ± 9.54 vs.140.33 ± 7.74 in IP group,137.13 ± 7.39 vs.142.40 ± 9.18 in PCV group,all P ＜ 0.01;MAP (mmHg):55.07 ± 4.43 vs.65.87 ± 4.46 in SI group,58.82 ± 6.04 vs.64.02 ± 7.65 in IP group,57.89 ± 4.71 vs.65.36 ± 5.37 in PCV group,all P ＜ 0.01],but it recovered immediately.CVP in all three groups was increased during RM [cmH2O (1 cmH2O =0.098 kPa):11.60±0.99 vs.5.53±0.74 in SI group,10.33± 1.35 vs.5.40±0.74 in IP group,10.20±0.94 vs.5.80±0.68 in PCV group,all P ＜ 0.01].There was significant difference in CVP during RM among three groups (F =7.327,P =0.002),and CVP in SI group was higher than that of other two groups (both P ＜ 0.05).CVP returned to the former level in 15 minutes after RM in IP and PCV groups,and recovered in 30 minutes in SI group.Conclusions All of the RM methods can effectively improve oxygenation and pulmonary compliance of the children with complication of ARDS,and they complement the inadequacy of lung protective ventilation.PCV and IP are more effective than SI in the uniform re-expansion of alveoli after RM and recovery of hemodynamics.
