Objective To evaluate the surgical approaches for gastric carcinoma accompanied by portal hypertension ( PHT).Methods The clinical data of 22 patients with PHT undergoing operation during 5 years were retrospectively analyzed.The liver function was Child's A in 12 cases, Child's B in 10 cases.Total gastrectomy + pericardial devascularization was performed in 11 cases, distal subtotal gastrectomy in 9 cases, distal subtotal gastrectomy + splenectomy in one, distal subtotal gastrectomy + pericardial devascularization in one.12 cases with Child's A underwent D2 lymph node (LN) dissection and 10 cases with Child's B were treated with D1 LN dissection.Liver biopsy was taken in all patients.Results Postoperative complications developed in 50% and mortality rate was 9%.The rate of liver function deterioration in patients of Child A ungergoing D2 lymph node dissection was 42% , and that of patients with Child B was 70%.The rate of postoperatiave complications in patients with Child A ungergoing D2 lymph node dissection was 25% , while that of patients with Child B was 80%.There was no significant difference in liver function deterioration rate between Child A and Child B (P ＞ 0.05) , but the rate of postoperative complications in Child A is much lower than those in Child B(P ＜ 0.05).The complication rate in patients receiving PHT targeting measures was 77% ,much higher than 11% in those without concurrent treatment of PHT ( P ＜ 0.05 ).Conclusions Individualized surgical approache is crucial for treatment of gastric carcinoma accompanied by PHT.Surgical treatment should be on the basis of liver function and the severity of PHT.

Objective To explore the relationship between the CHADS2 score and short-term prognosis in acute ischemic stroke patients with nonvalvular atrial fibrillation. Methods Consecutive ischemic stroke patients with nonvalvular atrial fibrillation who were hospitalized within 7 days after stroke were registered.Patients were divided into 3 groups on the basis of CHADS2 pre-stroke score (0 to 1,2,3to 6).And recovery was assessed by modified Rankin Scale (mRS) at 3 months follow-up (mRS ≤ 2reflected good prognosis,and mRS ≥ 5 implicated unfavorable outcome).After screening the risk factors affecting prognosis using univariate analysis,the relationship between CHADS2 score and prognosis was estimated using logistic regression model.Results Of 203 patients enrolled,the CHADS2 score of 0-1,2,3-6 were present in 72,53 and 78 respectively.Patients with the higher CHADS2 score had a higher initial NIHSS score (9.8,12.6,13.0,F =3.404,P =0.008 ),more likely to receive nosocomial pulmonary infection( 12.5％,34.0％,39.7％,x2 =14.643,P =0.001 ),negatively related to good prognosis (x2 =28.542,P =0.000 ) and positively related to unfavorable outcome ( x2 =23.575,P =0.000 ).Logistic regression model results suggested that CHADS2 score was an independent predictor of good prognosis and unfavorable outcome. Compared with CHADS2 score 3-6, CHADS2 score 0-1 was independently associated with good prognosis ( OR =5.018,95 ％ CI 2.055-12.560 ).And compared with CHADS2 score 0-1,CHADS2 score 3-6 was independently associated with unfavorable outcome ( OR =6.197,95％ CI1.670-22.996 ).Conclusions CHADS2 pre-stroke score appears to be useful in prediction of stroke outcome for patients with nonvalvular atrial fibrillation.After acute ischemic stroke,the patients with the lower CHADS2 score (0-1) are more likely to achieve good prognosis,inversely,the patients with the higher CHADS2 score (3-6) are more likely to achieve unfavorable outcome.

BACKGROUND:As one of the main active ingredients in epimedium, icari n plays an important role in bone defect repair. Sustained and effective concentration of icari n in vivo is essential for bone damage repair.
OBJECTIVE:To recommend the research progress of epimedium glycoside for bone repair and to explore the pharmaco-active concentration of icari n.
METHODS:A computer-based online search of CNKI database (http://www.cnki.net/) and PubMed database (http://www.ncbi.nlm.nih.gov/PubMed) from January 2000 to October 2013 was performed for related articles of the effect of icari n for bone defect repair and bone damage repair. The key words were“icari n, concentration, bone”in Chinese and English. After repeated articles were excluded, 76 related articles were screened out and 44 of them met the inclusive criteria.
RESULTS AND CONCLUSION:The icari n-released scaffold materials can induce the osteogenic differentiation of bone marrow-derived mesenchymal stem cells, promote the viability of osteoblasts and inhibit the resorption of osteoclasts, thus repairing bone tissue. It is certain that icari n promotes cellular dif erentiation, however whether it can promote cellular proliferation remains unclear. The pharmaco-active concentration of icari n ranges from10-8 to 10-5 mol/L, but clinical trial has not yet been carried out, and specific drug concentration is uncertain, which needs further exploration.

Objective To study the association of MIF-173 locus polymorphism and the risk of prostate cancer (PCa) in China. Methods A case control study including 259 PCa patients and 301 age-matched controls was conducted. The polymorphisms of MIF-173 locus were analyzed by poly-merase chain reaction restriction fragment length polymorphism (PCR-RFLP) technique using genomic DNA isolated from peripheral blood lymphocytes. The correlations between the susceptibility to PCa and different genotypes were compared. The effect of age, smoking method and family history of canc-er were also analyzed. Results The rate of the MIF-173 * C variant allele of the PCa patients(n=259) was significantly higher than that of the controls (n=301) (36.0% vs 15.0%). The MIF-173 *C variant allele could significantly increase the risk of PCa (OR=2.96,95%CI: 1.92-4.57). Peo-ple with older age (age>70) or family history of cancer, who carried MIF-173 * C allele demonstra-ted a significantly increased risk in comparison with those carrying wild genotype of G/G(OR=3.66, 95%CI=2.02-6.62;OR=3.26, 95%CI=1.24-8.55). Conclusion These results suggested that polymorphisms of MIF-173 locus appear to influence the risk of PCa and may have synergistic effect with age and family history of cancer.

Objective To investigate the effect of physician guidance on cigarette cessation in current smokers with chronic obstructive pulmonary disease(COPD).Methods Cigarette cessation education and routine telephone follow-up was provided for 70 COPD patients.Pulmonary function and exhaled carbon monoxide level were detected every 3 months.Results After 6 months' follow-up,28 participants(40.00%) successfully quitted cigarette smoking.Seventeen subjects (24.28%) experienced relapse,with mean cessation time(3.08±0.33) months.Once receiving physician guidance,5 re-attempted to quit cigarette smoking,and 12 reduced tobacco consumption. Sixteen subjects(22.86%) did not quit smoking,although the mean cigarette consumption per day was decreased by 60%.Nine participants (12.86%) showed no change in smoking habit. Conclusion Physician guidance could impreve the rate of cigarette cessation in COPD patients.Intensive intervention may be correlated with successful smoking cessation.

OBJECTIVE To evaluate the clinical outcome of submucosal inferior turbinectomy and outfracture surgery of inferior turbinates. METHODS All patients receiving two different operations were measured by acoustic rhinometry and questionnaire of QOL at preoperative 1 week and postoperative 12 months, seperately. RESULTS Forty-seven patients with inferior turbinate hypertrophy were enrolled in this study. Evaluation of SNOT-20 discovered both surgeries could improve patients' QOL with similar outcome. Preoperative '5 important items' in patients with inferior turbinate hypertrophy were 'lack of a good night's sleep', 'need to blow nose', 'thick nasal discharge', 'fatigue' and 'dizziness'. Postperative '5 important items' were 'postnasal discharge', 'runny nose', 'sneezing', 'reduced concentration' and 'reduced productivity'. Both surgeries could make acoustic rhinometry parameters change obviously, such as minimal cross-sectional area, 0-5 cm nasal volume(NV) and 2-5 cm NV. Furthermore, submucosal inferior turbinectomy produced more volume in nasal cavity than outfacture surgery, (7.28±2.01)cm3 vs (6.01±1.22)cm3, (5.99±1.87)cm3 vs (4.23±1.08)cm3(P<0.05), seperately. There was no correlation between the data of SNOT-20 and acoustic rhinometry. CONCLUSION We recommend outfracture surgery of inferior turbinate as the preferred surgical choice for patients with mild inferior turbinate hypertrophy.
