Objective To investigate the effect of standard remnant liver volume (SRLV) on liver insufficiency after hepatectomy in cirrhotic patients with hepatocellular carcinoma (HCC).Methods Sixty-seven HCC patients with liver cirrhosis were involved in this study.The following parameters were obtained in all cases:total liver volume (TLV),resected liver volume by surgery,body surface area (BSA),remnant liver volume (RLV)and SRLV.Compared analysis of relationship between liver insufficient and the parameters as well as the age of patients,duration of operation and blood lose etc.was carried out,in order to establish the security threshold of SRLV.Results According to the postoperative liver function,the patients were divided into 2 groups:Group A,52cases with mild liver dysfunction; Group B,15cases among them 12 with moderate and 3 with severe liver insufficiency.Statistical analysis showed that the difference of TLV,duration of operation,intra-operative blood lose and age between Group A and B were insignificant(P＞0.05).However,that of RLV and SRLV were significant(P＜0.05).The average SRLV in Group A was 562±89 ml/m2 and 410±87 ml/m2 in Group B (P＜＜0.01).The security threshold of SRLV was 438 ml/m2 calculated by receiver operating characteristic (ROC)in our patients.Then randomly selected sixty HCC patients,the incidences of moderate and severe liver insufficiency postoperative in the SRLV≤438 ml/m2 and SRLV＞438 ml/m2 patients were 92.3％and8.5％ (P＜0.01).Conclusions It is suggested from our present study that SRLV is a good predictor for post-operative liver function reserve in patients with cirrhotic HCC.Its security threshold is 438 ml/m2,and the risk of occurring hepatic failure will be high postoperatively when patient,s SRLV is less than this value.

Objective: To study the effect of light quality on the growth as well as triterpenic acid content and component of Ganoderma lucidum mycelium. Methods: Light-emitting diode (LED) was used as sources of light, the growth index, content and component of triterpenic acids in G. lucidum mycelium cultured under different LED conditions were investigated along with culture time. Results: The growth rate, morphology, biomass, total contents and components of triterpenic acid in G. lucidum mycelium varied under different lights. The mycelium cultured under blue light maintained stable growth during the whole period; Under red light, both growth rate and biomass of mycelium were the highest in early time, subsequently, decreased sharply and grew slowly. Under green light, both growth rate and biomass of mycelium were the lowest in early and medium phases, while increased significantly later, especially dry matter. Triterpenic acids were highly produced on the day 7 of cultivation, while decreased in content and increased in types. Green light and blue light had a distinct advantage of improving the type and content triterpenic acids in G. lucidum. Conclusion: Light quality affects the growth as well as the content and component of triterpenic acids in G. lucidum mycelium, and blue light irradiation is the best for the steady growth and triterpenic acids accumulation.

Objective To explore the relationship between acid pocket and acid reflux in gastroesophageal reflux disease (GERD).Methods From March 2011 to January 2012,29 patients with GERD were enrolled and nine healthy individuals were set as control.All objects of this study accepted esophageal manometry test,acid pocket test,test of the occurrence time of acid pocket and ambulatory 24 hours pH monitoring.The t-test was performed for comparison between two groups.The relationship between the incidence of GERD and acid pocket was analyzed by Logistic regression analysis.Pearson correlation analysis was used for correlation analysis.Results The percentage of acid pocket in GERD group and control group was 58.6％ (17/29) and 5/9,respectively,and the difference was not statistically significantly (P＞0.05).The duration time of acid pocket was (56.3±44.7) minutes in GERD group which was longer than that of control group ((16.0±8.2) minutes) and the difference was statistically significant (t=1.970,P＜0.01).There was no statistical significance in the average pH value of acid pocket between GERD group with acid pocket (2.8 ± 1.3) and that of control group with acid pocket (1.9±0.5,P＞0.05).The duration time of acid pocket was correlated with the longest reflux time in GERD group with acid pocket (r=0.550,P＜0.01).The peak velocity of esophageal motility in GERD group ((3.3±0.6) cm/s) was lower than that of control group ((5.0±4.1) cm/s) and the difference was statistically significant (t=-1.354,P＜0.05).The peak velocity of esophageal motility in GERD group with acid pocket ((3.2±0.6) cm/s) was lower than that of control group with acid pocket ((7.2± 6.3) cm/s) and the difference was statistically significant (t=-2.693,P＜0.05).Conclusions The duration time of acid pocket in GERD is correlated with the time of acid reflux.Esophageal dysmotility may be related with the pathogenesis of GERD and the occurrence of acid pocket.

Objective Preparation of a stable and reliable atrioventricular blockage ( AVB) animal model is of great im-portance to anti-arrhythmic drugs and biological engineering research .The aim of the article was to establish a rat model of AVB in-duced by chemical ablation, providing an effective animal model for the development of new drugs . Methods 60 adult SD rats were randomly divided into 4 groups(n=15): normal saline (NS) group, Verapmil (Ver) group, chemical ablation group 1 and chemical ablation group 2.0.9%NaCl (5 mg/kg) was injected into caudal vein of each rat in NS group .Verapmil (5 mg/kg) was injected into the caudal vein in Ver group.Anhydrous ethanol(50μL)was injected into atrioventricular groove area in chemical abla-tion group 1.Anhydrous ethanol(50μL) was injected into atrioventricular node area in chemical ablation group 2.The electrocardio-grams of the rats were examined by electrophysiological recorder.HE staining and Connexin 43 (CX43) immunohistochemical tech-nique were applied to atrioventricular junctions of the rats . Results A rat model of AVB was successfully established .Compared with NS group([45 ±2.24]per field of view), there was a significant decrease in the CX43 expressions of chemical ablation group 1 and group 2 ([15.20 ±2.23]per field of view, [22.10 ±4.70]per field of view)(P<0.05).Concerning NS group and Ver group, myocyte tissues of the atrioventricular nodal region were detected to remain in order without obvious changes and the expres-sion of CX43 immunoreactive protein was obvious under light microscope.As to chemical ablation group 1 and group 2, myocyte tissues were in degenerative necrosis and the expression of CX43 im-munoreactive protein was in lighter staining.Compared with Ver group, the incidence rate(73.3%, 60.6%) and the mortality rate (33.3%, 26.7%)of third-degree AVB decreased remarkably(P<0.05). Conclusion Chemical ablation can be induced to estab-lish a stable and reliable rat model of AVB , providing an effective
animal model for the research and development of new anti-arrhythmic drugs.
