Objective　To study the therapeutic effect of hepatic artery and portal vein dual perfusion chemotherapy (AVPC) combined with intratumoral injection of lipiodol-ethanol (ITILE) for unresectable primary hepatic carcinoma (PHC). Methods　138 pathologically proved and unresectable PHC cases were divided into two groups: Group A (80 cases), treated with AVPC through hypodermic implanted drug delivery pumps. Group B (58 cases), treated with AVPC plus ITILE. Results　　The secondary resection rate was 2.5% in group A, while 　 12.1% in group B, (P<0.05); The 0.5, 1, 2 years survival rate in group A was 56.3% 45.0% and 21.2%, in group B 81.0% 61.2% and 39.6% respectively. there were significent difference between two groups in 0.5,1,2 years survival rate respectively (P<0.05); the complication occurrence rate was found no significant difference between two groups (P>0.05). Conclusions　The therapeutic effect of AVPC plus ITILE for unresectable PHC is much better than that of AVPC alone.

Objective: To examine the causal relationships between obesity, peripheral blood lipid indicators and non-small cell lung cancer (NSCLC) using Mendelian randomization (MR) method, so as to provide the basis for developing NSCLC prevention and control strategies. Methods: Genetic variation data of three obesity evaluation indicators, including body mass index (BMI), body fat ratio (BFR) and waist-to-hip ratio (WHR), and seven peripheral blood lipid indicators, including triglyceride (TG), total cholesterol (TC), low density lipoprotein cholesterol (LDL-C), high density lipoprotein cholesterol (HDL-C), apolipoprotein A1 (ApoA1), apolipoprotein B (ApoB) and lipoprotein a [LP (a)] were collected through genome-wide association studies (GWAS) and related public databases. Potential causal relationships between obesity, peripheral blood lipid indicators and NSCLC were analyzed using inverse-variance weighted (IVW) method and multivariable MR analysis upon a random effect model. Heterogeneity and horizontal pleiotropy of instrumental variables were evaluated using Cochran's Q test and MR-Egger regression. Results: There was statistically association between BMI with NSCLC (OR=1.256, 95%CI: 1.087-1.451); there were no statistically associations between BFR, WHR, seven peripheral blood lipid indicators and NSCLC (all P>0.005). There was heterogeneity in the association between BMI, BFR, WHR, TG, HDL-C and NSCLC (all P<0.05); no horizontal pleiotropy of instrumental variables was found (all P>0.05). There was no statistically association between BMI and NSCLC after adjusting BFR (OR=1.367, 95%CI: 0.878-2.128); there was still statistically association between BMI and NSCLC after adjusting WHR and peripheral blood lipid indicators (both P<0.05). Conclusions The increase of BMI is associated with the increased risk of NSCLC incidence. BFR may be a potential influencing factor for the association between BMI and NSCLC.

To explore the clinical characteristic and intervention strategies for pregnancy complicated with heart failure. The clinical data of 67 pregnant women with heart failure during January 1998 to December 2010 were collected and analyzed.The rate of heart failure in pregnancy with heart diseases was 31％ (67/216).The causes of pregnancy complicated with heart failure were peripartum cardiomyopathy ( n =33,49％ ) and hypertensive disorder complicating with pregnancy heart disease( n =28,42％ ).Heart failure in pregnancy appeared at an average of (36.0 ± 2.7 ) weeks.The average terminating time of pregnant women with heart failure was ( 36.5 ± 2.1 ) weeks.Cesarean section was the main safe choice of delivery for pregnant women with heart failure.The average weight of newborns for pregnant women with heart failure was(2517 ±541 )g.The rate of neonatal asphyxia was 22％ (11/50).Strengthening routine antenatal examination and treating pregnant complications timely can prevent and reduce the incidence of heart failure.

Objective To evaluate the safety of helical tomotherapy (HT) for hepatocellular carcinoma confined to the liver,and to investigate the efficacy of HT by comparison with three-dimensional conformal radiotherapy (3DCRT).Methods In June 2011,hypofractionated HT was performed in 35 patients with unresectable hepatocellular carcinoma confined to the liver who had no distant metastasis or tumor thrombosis.The dose in each fraction increased from 2.4 Gy to 5.0 Gy with a median dose of 3.2 Gy.The median dose for the total treatment was 50.0 Gy.Within the same period,45 patients received conventionally fractionated 3DCRT with a median dose of 54.0 Gy.The adverse reactions,clinical outcomes,and survival time were compared between the two groups.The survival rate was calculated with Kaplan-Meier method,and log-rank test was used to estimate statistical significance of survival differences.Multivariate analysis of survival was carried out with Cox' s regression model.Results There were no significant differences in adversc reactions between the two groups.The objective response rate was significantly higher in the HT group than in the 3DCRT group (60％ vs.33％,P=0.024).There was no significant difference in the disease control rate between the two groups (94％ vs.89％,P=0.459).The HT group showed significantly higher 1-,2-,and 3-year overall survival rates than the 3DCRT group (97％ vs.80％,P=0.025;81％ vs.55％,P =0.008;67％ vs.50％,P =0.048).The multivariate analysis indicated that tumor smaller than 8 cm,transarterial chemoembolization before radiotherapy,and HT were associated with improved survival (P=0.005;P =0.000;P=0.002).Conclusions HT shows an advantage in precise treatment of hepatocellular carcinoma confined to the liver.With acceptable toxicity,hypofractionated HT shortens the treatment duration and improves the survival in patients.

OBJECTIVE: To assess the effect of one-stage repair of secondary nasolabial deformity and nasal septoplasty for cleft patients on nasal airway resistance (NAR). METHOD: Using active anterior rhinomanometry, NAR was measured in eighteen patients with cleft lip and palate who suffered form one-stage repair of secondary nasolabial deformity and septoplasty at per-and-post operation. RESULT: NAR was (0.664 +/- 0.200) kPa/(s x L) before operation, (0.304 +/- 0.180) kPa/(s x L) six months after operation, and (0.396 +/- 0.250) kPa/(s x L) twelve months after operation respectively. The differences are statistically significant (P < 0.01) between the NAR before and after operation. Subjective impression score of nasal patency was 7.5 +/- 1.5 before-operation, 2.1 +/- 2.0 after-operation for six months, 3.0 +/- 2.4 after-operation for twelve months. There are significant differences in the subjective impression score of nasal patency as well (P < 0.01). CONCLUSION Correction of septal deformities play a very important role in the operation for secondary nasolabial deformity, which can decrease NAR and improve the subjective impression of nasal patency.

In order to control the quality of Vigna radiata, the quality control method and standard were established in this study. The tests of water content, ash and ethanol-soluble extractives of V. radiata were carried out according to the methods recoded in appendix of Chinese Pharmacopeia (2010 edition, volume 1). The TLC method was established by using vitexin and isovitexin as references, and a mixture of acetate-method-water (10: 1.7 : 1.3) as the developing solvent system on GF254 thin layer plate. The contents of vitexin and isovitexin were determined by HPLC on a Prevail C18 (4.6 mm x 250 mm, 5 microm) column, using acetonitrile: water (23 : 77) as mobile phase at a flow rate of 1.0 mL x min(-1). The column temperature is 30 degrees C and the detection wavelength is 337 nm. As a result, vitexin, isovitexin and the other constituents were well separated on TLC detected under the UV light (254 nm). The methodology validation for the assay of vitexin and isovitexin presented that they were in good linear correlation in the ranges of 6.12-98 mg x L(-1) and 6.85-109.6 mg x L(-1), with the regression equations of Y = 46.213X - 7.100 (r = 1.000) and Y = 54.515X + 6.829 (r = 1.000), and the average recoveries were 98.2% (RSD 1.9%) and 97.2% (RSD 0.79%), respectively. The content ranges of vitexin and isovitexin from 25 different batches of V. radiata were 1.076-2.062 mg x g(1) and 1.127-2.303 mg x g(-1), respectively. suggesting that the qualities of V. radiata are relatively stable. The ethanol-soluble extractives, water content and total ash of 25 samples varied in the ranges of 13.27% - 18.46%, 9.59% - 12.43% and 2.63% - 3.53%, respectively. All of the above data proved that the established quality of control method V. radiata is specific and accurate, which can be used for the quality control of this drug.
