ObjectiveTo evaluate the modified Barcelona Clinic Liver Cancer (BCLC) staging system for predictability of intrahepatic recurrence for patients with hepatocellular carcinoma (HCC) following curative hepatectomy.MethodsA retrospective study was conducted on 197 consecutive patients with HCC who underwent curative hepatectomy in our department from Jan.2008 to Jan.2011.Univariate and multivariate analyses using Cox proportional hazard model were used to evaluate possible association between clinicopathologic factors and early postoperative intrahepatic recurrence (ER).Receiver operating characteristics (ROC) analysis with calculation of the area under the curve (AUC),sensitivity,and specificity were applied to define the cutoff point values for possible meaningful continuous variables where appropriate.A comparison between the differences in AUC was used to assess BCLC and a modified BCLC (M-BCLC) staging system for their predictive ability of ER.Risk stratification according to calculated M-BCLC was applied to find differences of ER at various time points after curative hepatectomy.ResultsDuring follow-up,111 patients developed ER.The 6-,9-,12-,18- and 24-month cumulative recurrent rates were 26.9％ (53/197),37.6％ (74/197),45.2％(89/197),53.8％ (106/197) and 56.3％ (111/197),respectively.Multivariate analysis revealed thatthe severity of concomitant cirrhosis,elevated AFP≥185.6 μg/L and BCLC staging were risk factors of ER.A M-BCLC was proposed based on the results of multivariate analysis.The severity of cirrhosis and elevated AFP values were included in the BCLC staging.This M-BCLC exhibited better performance.It predicted at different time points of ER at postoperative 9,12,18 and 24 months to be significantly better with M-BCLC than BCLC using AUC drawn from ROC.No significant difference was found with ER prediction at 6 months.The M-BCLC also demonstrated a ER prediction with AUC of 0.710 (95％ CI,0.630-0.790) and achieved a sensitivity of 83.0％,a specificity of 51.9％as calculated from ROC with M-BCLC≥2.913.Further risk stratification according to the M-BCLC at various cutoff point values revealed the ER occurrence rates amongst the different risk groups to be significantly different when compared with the median ER time (17.9 mons,9.9 mons vs 5.7 mons,x2=25.770,P=0.000,Log-Rank test).ConclusionA modified BCLC staging system based on multivariate analysis improved the predictability of ER following curative hepatectomy for HCC.

OBJECTIVE: To investigate the value of cementless total hip arthroplasty (THA) for the treatment of Crowe type Ⅲ developmental dysplasia of hip (DDH) in adults.

Objective To investigate the effect of glucose supplement on AMPK activation in myocardium of exercised rats by measuring the myocardial AMPK activation and glycogen content after acute exercise training.Methods Rats were subjected to an acute endurance exercise and glucose supplement in varying doses and time points before and after exercise.The dynamic changes of myocardial AMPK activities was measured with Western blotting, changes of myocardial glycogen content were measured with Anthrone method.Results AMPK activation in myocardium of exercised rat was increased significantly throughout the exercise, and remained at a higher level 1 hour after acute exercise.However the level of AMPK activity was not significantly increased in exercised rat with glucose supplement.Glycogen content was not significantly changed after exercise.Rats subjected to lower dose glucose supplement did not show significant changes in glycogen content neither.But glycogen content was significantly increased in rats at 24 hours after exercise, subjected to higher dose of glucose supplement.Conclusions 1) Acute exercise induces a significant increase in AMPK activation in myocardium of exercised rats.Glucose supplement significantly inhibites the activation of AMPK induced by acute exercise.(2) Higher dose glucose supplement significantly increases glycogen content in the rat myocardium 24 h after exercise.

OBJECTIVE:To establish the fingerprint of Artemisia apiacea to identify common model and evaluate the quality coherence of the commercially available A. apiacea decoration pieces in Chongqing. METHODS:HPLC method was performed on the column of Waters XTerra C18 with the mobile phase consisted of methanol-0.1% phosphoric acid(gradient elution)at the flow rate of 1.0 ml/min. The detection wavelength was 220 nm,column temperature was 30 ℃ and the sample size was 10 μl. The simi-larity of 12 batches of samples was evaluated by TCM Chromatogram Fingerprint Similarity Evaluation System(2004A edition);a common model of fingerprints was identified by principal component analysis(PCA)and cluster analysis(CA). RESULTS:Total-ly 11 batches of samples were screened to establish common model of fingerprints and 16 common peaks were obtained,among which,3 common components were identified;RSDs of precision,stability and reproducibility tests were lower than 2.53%. The similarity of 11 batches of A. apiacea and reference chromatogram was more than 0.990. CONCLUSIONS:The method is stable and easy,and can provide reference for the scientific quality evaluation and control of A. apiacea;the quality of commercially available A. apiacea decoration pieces is generally good,however,there is still a little number of batches with poor quality. The production procedures and supervision of A. apiacea decoration pieces should be strengthened.

ObjectiveTo evaluate the impact of anatomic and non-anatomic liver resection on prognosisofpatientswithsmallhepatocellularcarcinoma( HCC ) usingaMeta-analysis.MethodsLiterature on anatomic versus non-anatomic liver resection for the treatment of small HCC ( ≤5 cm) was retrieved. ResultsFour nonrandomized controlled trials were included consisting of 776 patients:484 undergoing anatomic liver resection and 292 non-anatomic resection.The age ranged from 53.4 to 63.0 years.Male ∶ female ratio was 3.56 ∶ 1.87.1％ patients were Child-Pugh class A.Most patients (94.5％ ) had a single tumor.No significant differences were found conceming the 1,3,and 5 year disease-free survival rate between the two groups.There was no significant difference in overall survival and disease-free survival between the two groups at 1,3,and 5 years.Sensitivity analysis found anatomic resection was superior to non-anatomic resection in 3 year disease free survival rate (OR =0.72,95％ CI:0.52 - 0.99,P =0.04). ConclusionsAnatomic liver resection elevated the 3 year disease free survival rate of patients with small hepatocellular carcinoma when compared with non-anatomic hepatectomy but failed to further elevate long-term disease free survival and overall survival.

OBJECTIVETo study the effect of the Chinese compound prescription Chaihu Shugan Tang (CHSGT) on the excitability in the cerebral cortex and hippocampus (different brain regions) of pentetrazole (PTZ)-kindled chronic epileptic rats.

METHODTo establish the model of chronic kindling rats intraperitoneal injected with pentylenetet. Fully kindled rats were randomized into control and experimental groups for intragastric administration of normal saline (control, model), Sodium Valproate and CHSGT at the high, medium and low doses for 4 consecutive weeks. The content of 2-NBDG, the glutamate (Glu) and the aspartate (Asp) in different brain regions of rats were detected by fluorescence imaging techniques and HPLC assay respectively.

RESULTCHSGT at the high, medium and low doses all significantly decreased the content of 2-NBDG, the Glu and the Asp in different brain regions of chronic epileptic rats (P < 0.01).

CONCLUSIONCHSGT can inhibit the excitability in different brain regions of PTZ-induced epileptic rats, by decreasing the level of excitatory neurotransmitter maybe one of its antiepileptic mechanisms.

Objective To evaluate the early effect and safety of artificial hip replacement for treating senile osteoporosis femoral neck fractures with different prostheses choice. Methods From January 2006 to April 2014, 387 patients with senile osteoporotic femoral neck fractures received artificial hip replacement. Their average age was 65 to 98 years old,with the average of 76.9 years old. Four prostheses were used in the artificial hip replacement, including 107 cases of biological total hip,94 cases of bone cement type total hip,104 cases of biotype artificial femoral head,and 82 cases bone cement artificial femoral head. We compared the operation time,bleeding amount, postoperative ambulation time,postoperative complication rate among the four prostheses. Results The biological hip replacement were superior to bone cement type in the operation time(50±10.3 min vs 61±11.5 min), bleeding amount(149±27.7 ml vs 205±47.3 ml)and postoperative complications(21% vs 38%),with statistical significant differences(P < 0.05). Other observations showed no statistically significance. Conclusion The biotype artificial joint replacement is applicable to the younger patients with thick bone cortex and long life expectancy,while the bone cement artificial joint replacement is appropriate for weak senile patients with thin bone cortex.

Objective To assess the role of the different pancreatic islet β cell function index in the evaluation of glucose metabolism in different duration of type 2 diabetes mellitus (T2DM).Methods Normal glucose tolerance subjects without diabetes family history (NC group,48 cases) and T2DM patients (182 cases) were enrolled.The T2DM patients were divided into three groups:less than 5 years group (DM ＜5 group,74 cases),5-10 years group (DM5-10 group,51 cases) and more than 10 years group ( DM ＞10 group,57 cases).Oral glucose tolerance test (OGTT) and insulin release test were taken in all groups.Insulin resistance index (HOMA-IR) and whole body insulin sensitivity index [ISI(Matsuda)] were used to estimate insulin sensitivity,and early insulin secretion index ( △ I30/ △ G30) and glucose disposition index (DI) were used to evaluate the function of pancreatic islet β cell.Results HOMA-IR was increased and ISI (Matsuda) was decreased in DM ＜5 group,DM5-10 group and DM ＞10 group compared with those in NC group [HOMA-IR:8.78 ± 7.12,8.08 ± 3.67,7.84 ± 5.08 vs.4.76 ± 3.43;ISI(Matsuda):46.78 ± 29.00,36.71 ± 16.67,38.86 ±21.72 vs.61.13 ± 32.08,P ＜ 0.05],however,there was no significant difference among DM ＜5 group,DM5-10 group and DM ＞10 group.△ I30/ △ G30 and DI were decreased in DM ＜5 group,DM5-10 group and DM ＞10 group compared with those in NC group [ △ I30 △ G30:( 68.41 ± 361.52 ),(4.31 ± 3.42 ),(7.70 ± 5.78 ) mU/mmol vs.(92.65 ± 309.29) mU/mmol;DI:0.0421 ± 0.0123,0.0412 ± 0.0123,0.0363 ± 0.0116 vs.0.1151 ± 0.0236,P ＜ 0.05 ],and there was no significant difference in △ I30 / △ G30 among DM ＜5 group,DM5-10 group and DM ＞10 group,however,DI was decreased in DM＞10 group compared with that in DM＜5 group and DM5-10 group (P＜0.05).ConclusionsHOMA-IR,ISI (Matsuda),△I30/△G30 are not sensitive to evaluate the insulin resistance of different duration.DI can reflect the glucose utilization of pancreatic islet β cell earlier and the ability to regulate blood sugar steady state changes.
