Objective To investigate the expression and significance of β-catenin and peroxisome prolifera-tot-activated receptor-γ,(PPARγ) in bepatocellular carcinoma. Methods Tissue microarrays were established to detect β-catenin and PPARγ expression in 49 cases of hepatocellular carcinoma,49 cases of adjacent nontumoral liv-er tissue and 6 cases of normal liver tissue. The relationships between PPARγ and β-catenin as well as between PPARγ and clinicopathological parameters were observed. Results The aberrant expression rate of β-catenin was 69.39%,48.98 % and 0 respectively (P=0.001). The positive expression rate of PPARγ was 51.02%,30.61% and 0 respectively (P=0.016). Clinicopathological analysis revealed that the increase of PPARγ expression was not associated with age,tumor size,serum alpha fetoprotein (AFP) levels,tumor embolus of portal vein or inferior vena cava,and HBsAg infection(χ2=0.214,3.201,0.046,3.201,P>0.05 for each),but correlated with differentiation grades(χ2=4.693,P<0.05). Aberrant expression of β-catenin was associated with PPARγ expression(χ2= 5.130,P<0.05). Conclusion Aberrant expression of β-catenin may involve in the liver carcinogenesis. The high expression of PPARγ in hepatocellular carcinoma is significantly correlated with the clinicopathological characteris-tics. Detection of PPARγ is valuable for diagnosing hepatocellular carcinoma,and evaluating malignancy extent and prognosis.

Objective To explore the curative efficacy of astragalus injection on blood lipids and bone mineral density in patients with hemiplegia after ischemic stroke. Methods From January, 2014 to June, 2015, 116 patients with hemiplegia after ischemic stroke were col-lected and radomly divided into control group (n=54) and observation group (n=62). The control group received acupuncture based on con-ventional treatments, while the observation group received astragalus injection in addition. National Institutes of Health Stroke Scale (NI-HSS) and Ability of Daily Living Scale (ADL) were used to assess the neurologic impairment and the ability of daily living. The curative ef-ficacy and the levels of blood lipids and bone mineral density were observed. Results Compared with the control group, the curative efficien-cy increased (χ2=3.960, P<0.05). The score of NIHSS decreased (t=3.490, P=0.001), and the score of ADL increased (t=2.820, P=0.006). The levels of total cholesterol, triglyceride, low density lipoprotein cholesterol significantly decreased (t>4.190, P<0.001), however, the lev-el of high density lipoprotein cholesterol did not change (P>0.05). The densities in forearm, femur and Ward's area in the hemiplegia side in-creased (t>2.060, P<0.05). Conclusion Astragalus injection is effective on hemiplegia after ischemic stroke, which can increase the curative efficacy, alleviate the neurologic impairment, promote the ability of daily living, improve the blood lipids and increase the bone mineral den-sity.

Objective To establish and verify the prediction model for ischemic cardiovascular disease(ICVD)among the elderly population who were under the current health care programs. Methods Statistical analysis on data from physical examination, hospitalization of the past years, from questionnaire and telephone interview was carried out in May, 2003. Data was from was randomly selected to generate both module group and verification group. Baseline data was induced to make the verification group into regression model of module group and to generate the predictive value. Distinguished ability with area under ROC curve and the predictive veracity were verified through comparing the predictive incidence rate and actual incidence rate of every deciles group by Hosmer- Lemeshow test. Predictive veracity of the prediction model at population level was verified through comparing the predictive 6-year incidence rates of ICVD with actual 6-year accumulative incidence rates of ICVD with error rate calculated. Results The samples included 2271 males over the age of 65 with 1817 people for modeling population and 454 for verified population.All of the samples were stratified into two layers to establish hierarchical Cox proportional hazard regression model, including one advanced age group(greater than or equal to 75 years old), and another elderly group(less than 75 years old). Data from the statically analysis showed that the risk factors in aged group were age, systolic blood pressure, serum creatinine level, fasting blood glucose level, while protective factor was high density lipoprotein; in advanced age group, the risk factors were body weight index, systolic blood pressure, serum total cholesterol level, serum creatinine level, fasting blood glucose level, while protective factor was HDL-C. The area under the ROC curve (AUC)and 95%CI were 0.723 and 0.687-0.759 respectively. Discriminating power was good. All individual predictive ICVD cumulative incidence and actual incidence were analyzed using Hosmer-Lemshow test, x 2=1.43, P=0.786, showing that the predictive veracity was good.Conclusion The stratified Cox Hazards Regression model was used to establish prediction model of the aged male population under a certain health care program. The common prediction factor of the two age groups were: systolic blood pressure, serum creatinine level, asting blood glucose level and HDL-C. Thc area under the ROWC curve of the verification group was 0.723, showing that the distinguished ability was good and the predict ability at the individual level and at the group level were also satisfactory. It was feasible to using Cox Proportional Hazards Regression Model for predicting the population groups.

Objective To investigate the 6-year accumulative incidence rate of ischemic cardiovascular disease (ICVD) and its related risk factors. Methods Baseline population was all from an elderly population with members all born before 1-1,1938 and under health care programm.Data was recorded in a database of a hospital and baseline of subjects under research was aged ＞65years. People that had had ICVD at baseline were excluded. Risk factors under research would include: age at the baseline study, gender, body mass index, systolic blood pressure, serum cholesterol level, serum triglyceride level, serum high-density lipoprotein level, serum triglyceride level, serum apolipoprotein A1 level, history of diabetes mellitus and cigarette smoking etc. Single factor analysis was carried out using person-years as time of study, then calculating the person-year incidence and the accumulative incidence rate at different levels related to baseline risk factors.Multivariate analysis was under Cox Proportional Hazards Regression Model. Results Baseline population included 2271 elderly men, with the 6-year cumulative prevalence rate of ICVD as 23.56%, and the person-year prevalence rate was 45.41‰. Single factor analysis showed that the ICVD events positively related to variables which including systolic blood pressure, body mass index,serum cholesterol level and serum triglyceride level, serum apolipoprotein A1 level, status of diabetes mellitus and cigarette smoking. The ICVD events negatively related to variables as serum high-density lipoprotein levcl and serum creatinine level. Results of multivariate analysis showed that high systolic pressure, diabetes mellitus, serum creatinine level, Body Mass Index were the main risk factors. The serum high-density lipoprotein level served as the main protective factor. Conclusion The aged male population under health care programme was high in the ICVD prevalence rate, suggesting that programmes as controlling blood pressure, blood glucose, and increasing serum high-density lipoprotein levels were effective measures to decrease the ICVD events.

Background Glaucoma is primarily characterized by the damage of retinal ganglion cells.The macular ganglion cell complex (GCC)thickness can be quantitatively measured using spectral domain optical coherence tomography(SD-OCT). Objective This clinical study was to explore the macular GCC thickness change in primary open-angle glaucoma (POAG) patient with SD-OCT. Methods A serial case-controlled study was designed.A total 101 eyes of 101 POAG patients and 41 normal eyes of 41 age- and refract power-matched normal subjects were cnrolled in the study.POAG patients were assigned to normal perimetry POAG group,early stage POAG group,advanced POAG group and late stage POAG group.Average macular GCC thickness(GCC-Avg),superior GCC thickness(GCC-Sup) and inferior GCC thickness (GCC-Inf)of subjects were measured by SD-OCT and compared among POAG patients and normal controls.Peripapillary retinal nerve fiber layer(RNFL) thickness was measured with time domain OCT(TD-OCT).The correlation between GCC thickness with RNFL thickness or mean deviation(MD) of perimetry were evaluated and analyzed.Informed consent was obtained from each patient prior to entering this study.Results GCC-Avg thickness,GCC-Sup thickness and GCC-Inf thickness were significantly decreased in the normalperimetry POAG group and early stage POAG group compared with the normal control group (GCC-Avg:t =5.411,10.247,P ＜ 0.01 ; GCC-Sup:t =6.171,9.484,P＜ 0.01 ; GCC-Inf:t =5.281,8.592,P ＜ 0.01 ).Also,GCC-Avg thickness,GCC-Sup thickness and GCC-Inf thickness were significantly decreased in the advanced POAG group compared with the early stage POAG group ( GCC-Avg:t =4.246,P＜0.01 ; GCC-Sup:t - 2.419,P - 0.019 ; GCC-Inf:t =4.636,P＜0.01 ),and GCC-Avg thickness,GCC-Sup thickness and GCC-Inf thickness were significantly decreased in the late stage POAG group compared with the advanced POAG group (GCC-Avg:t=2.095,P=0.040;GCC-Sup:t=2.756,P＜0.01:GCC-Inf:t =2.018,P =0.040 ).The positive correlations were seen between GCC-Avg thickness,GCC-Sup thickness,GCC-Inf thickness and RNFL-Avg thickness,RNFL-Sup thickness,RNFL-Inf thickness respectively( r =0.802,0.825,0.856,P ＜ 0.01 ).MD value of perimetry was positive correlated with GCC-Avg thickness in POAG patients ( r =0.601,P ＜ 0.01 ). Conclusions SD-OCT can quantitatively measure and differentiate the GCC thickness in POAG patients.The GCC thickness gradually decreases with the development of POAG.There exist a well correlation between visual field defect and RNFL thinning.

Taking mesoporous molecular sieve MCM-41 as a substrate, baicalin (BA) as template, acrylamide (AM) as the functional monomer, ethylene glycol dimethacrylate (EGDMA) as a cross-linking agent, ethanol as solvent, under thermal polymerization initiator of azobis isobutyronitrilo (AIBN) , a kind of selective recognition of baicalin surface molecularly imprinted polymer was synthesized. The surface morphologies and characteristics of the MIPs were characterized by infrared spectroscopy (IR) and transmission electron microscope (TEM). The adsorption properties of polymer microsphere for the template were tested by the dynamic adsorption equilibrium experiments and static adsorption equilibrium experiments. The experiment showed that the imprinting process was successfully and the well-ordered one-dimensional pore structure of MCM-41 was still preserved. Furthermore, molecularly imprinted polymers had higher selective ability for BA, then provided a new method for the efficient separation and enrichment of baicalin active ingredients from medicinal plants Scutellaria baicalensis.

OBJECTIVETo observe the clinical effect of electric stimulation of long-term retaining needle on analgesia after laparoscopic cholecystectomy (LC) and the impacts on the post-surgical flatus time.

METHODSUnder static absorptive composite general anesthesia, 90 cases of LC were randomized into three groups, 30 cases in each one. In the control group, the analgesia was not applied after LC. In the analgesia-pumper group, the patient controlled intravenous analgesia (PCIA) was used. In the needle-retaining group, the electric acupuncture stimulator was used. The needles were inserted transversely at Riyue (GB 24), Qichong (ST 30) and Yanglingquan (GB 34) and fixed with sterile sticker. Separately, in 8 h and 24 h after surgery, the electric acupuncture stimulation with disperse-dense wave, 2 Hz/100 Hz frequency was applied continuously for 30 min. Visual analogue scale (VAS), adverse reactions such as vomiting and nausea and the postoperative flatus time in 2, 4, 8, 12, 24 and 36 h after surgery were observed and recorded in the three groups.

RESULTSIn 2, 4, 8, 12 and 24 h after surgery, VAS scores in the needle-retaining group and the analgesia-pumper group were all lower than those in the control group (P < 0.05, P < 0.01). The analgesia effect at the above time points in the needle-retaining group was better than that in the analgesia-pumper group (all P < 0.05). There was not adverse reaction in the needle-retaining group. But there were 3 cases of somnolence, 6 cases of nausea and 3 cases of vomiting in the analgesia-pumper group, and 2 cases of nausea and 1 case of vomiting in the control group. The flatus time was quite earlier in the needle-retaining group as compared with the other two groups [(14.77 +/- 4.99) h vs (18.50 +/- 4.22) h, P < 0.01; (14.77 +/- 4.99) h vs (18.17 +/- 4.69) h, P < 0.05].

CONCLUSIONThe electric stimulation of long-term retaining needle is safe and effective in analgesia after LC. It avoids the adverse reactions of analgesics and promotes postoperative flatus.
