Objective To study the changes of serum vascular endothelial growth factor(VEGF)levels before and after interventional therapy of hepatocellular carcinoma(HCC),in order to find out a experimental proof that can start the anti-angiogenesis therapy.Methods Enzyme linked immunosorbentassay(ELISA)was used to detect serum levels of VEGF before transcathter arterial chemo-ebolization and in 24 hours,72 hours,7 days,14 days,30 days,after the operation,in 50 healthy individuals and 54 HCC pationts.Results Serum levels of VEGF in 54 patients with HCC were significantly higher than those in healthy individuals(P

Objective To analyze palm ratio of body surface area (B SA ) based on the body different surface area form ula. Methods Forty-four Chinese adult m ales w ere selected in this study. The contour of left single palm w as recorded and the palm area w as calculated by cut-paper w eighing m ethod. The body surface w as calculated by the height and w eight based on 12 form ulas of body surface area. Then, the palm ratio of BSA w as calculated. Results The average palm ratio of BSA w as (0.789±0.075)% . The data show ed statistically significant difference com pared with the traditional ratio (1% ) (P<0.05). Conclusion The ratio of B SA in Chinese adult m ale population show ed m ore accuracy com pared with the traditional ratio in this present study. The forensic evaluation can be affected by using the different ratio of B SA .

Objective: To compare the therapeutic effects of different doses of pioglitazone, a kind of peroxisome proliferator-activated receptor γ (PPARγ) agonist, on vascular dementia and explore how pioglitazone affects cerebral ischemia. Methods: Modified Pulsinelli's vessel ligation was used to establish a vascular dementia model in rats. Recognition, learning and memory were evaluated by Morris's water maze test. Immunoenzyme staining was used to determine the number of nerve cells. Immunofluorescence double-staining was used to examine the expression of PPARγ/nerve cells and PPARγ/astrocytes in different groups. Results: Both in pioglitazone groups and sham-operation group, the latency was reduced significantly compared to that in control group (P < 0.01). Sham-operation group had the largest number of neurons in the cortex, followed by low-dose pioglitazone group and high-dose pioglitazone group, and control group came last. Compared with control group, pioglitazone groups had more PPARγ expression in nerve cells, and the fluorescence intensity of PPARγ was stronger. Conclusion: Pioglitazone can induce the expression of PPARγ in neuron endochylema and astrocyte endochylema to protect nerve cells, and then to improve spatial learning and memory function in VD rats.

Objective To investigate the influences of Radix salvia miltiorrhiza (RSM) preconditioning on the expressions of phosphorylated eukaryotic initiation factor 2α (p-eIF-2ot) and caspase12 in hepatic ischemia reperfusion in rats.Methods Eighty Wistar rats were randomly divided into the control group (5 rats),sham operation group (25 rats),ischemia reperfusion (IR) group (25 rats) and RSM pretreated group (25 rats).Rats in the sham operation group,IR group and RSM pretreated group were subdivided into 5 groups at different time intervals (0,3,12,24 and 72 hours).Mter midline laparotomy,all structures in the hepatic portal were clamped for 45 minutes followed by different periods of reperfusion.Rats in the control group did not receive any treatment; rats in the sham operation group only received anatomy of the hepatic portal without clamping; rats in the RSM pretreated group received RSM by intravenous injection 30 minutes before ischemia at a dose of 6 ml/kg.Rats in the sham operation group and the IR group received a dose of normal saline as RSM pretreated group.The protein expressions of p-eIF-2α and caspase12 in the hepatic tissues of each group were detected by the Western blot,and the pathological changes of hepatic tissues in each group were detected by hematoxylin and eosin staining.All data were analyzed using the analysis of variance,LSD test or Games-Howell method.Results The relative expression of p-eIF-2α in the control group was 0.296 ± 0.038,and the relative expressions of p-eIF-2α in the sham operation group at different time points were 0.304 ± 0.048,0.298 ± 0.038,0.272 ± 0.042,0.266 ± 0.076 and 0.296 ± 0.043,with no significant difference between the 2 groups (P ＞ 0.05).The relative expression of p-eIF-2α in the IR group at 0 hour was 0.310 ± 0.034,which had no significant difference compared with the control group and the sham operation group (F =0.15,P ＞0.05).The relative expressions of p-eIF-2α in the IR group at 3,12,24 hours were 0.386 ± 0.021,0.710 ± 0.034,0.474 ± 0.017,which had no significant difference compared with the control group and the sham operation group (F =11.90,211.52,25.15,P ＜ 0.05).The relative expression of p-eIF-2α in the IR group at 72 hours was 0.336 ± 0.043,which was back to the level of the control group and the sham operation group (F =1.57,P ＞ 0.05).The relative expressions of p-eIF-2α in the RSM pretreated group at different time intervals were 0.278 ± 0.044,0.800 ± 0.079,1.056 ± 0.125,0.736 ±0.087 and 0.442 ± 0.047,which were significantly lower than the group at 3,12,24,72 hours (P ＜ 0.05).The relative expression of caspase12 in the control group was 0.983 ± 0.003,and the relative expressions of caspase12 in the sham operation group at different time intervals were 0.974 ± 0.004,0.983 ± 0.005,0.985 ± 0.003,0.981 ± 0.004 and 0.978 ± 0.004,with no significant difference between the 2 groups (P ＞ 0.05).The relative expression of caspase12 in the IR group at 0 hour was increased to 1.018 ± 0.076,while it had no significant difference compared with the control group and the sham operation group (F =1.43,P ＞ 0.05).The relative expressions of caspase12 in the IR group began to rise at 3 hours (2.056 ±0.067),and peaked at the 12 hours (2.804 ± 0.050),still at a relative higher level at 24 hours (1.882 ± 0.037),and began to decrease at 72 hours (1.282 ± 0.066),it had significant difference compared with the control group and the sham operation group (F=1290.69,6490.84,2898.71,103.61,P ＜ 0.05).The relative expressions of caspase12 in the RSM pretreated group at different time intervals were 0.998 ± 0.056,1.442 ± 0.066,1.990 ± 0.068,1.364 ± 0.056and 0.962 ±0.054.The relative expressions of caspase12 in the RSM pretreated group at 3,12,24,72 hours were significantly lower than the IR group (P ＜ 0.05).The results of pathomorphological examination showed that the hepatic lobules were integrated and the nucleuses were large and round in the control group an d the sham operation group; deformation of the hepatic lobule,smaller cell volume,nuclear condensation and necrosis were observed in the IR group; cell swelling and slight spotty necrosis were detected in the RSM pretreated group.Conclusions RSM could protect liver from damages during IR through up-regulating the expression of p-eIF-2α,reducing the apoptosis induced by endoplasmic reticulum stress.

Objective To investigate the relation of peripheral leukocyte total and its differential counts with urinary albumin(UAlb)in patients with type 2 diabetes.Methods The 564 subjects with type 2 diabetes were stratified according to UAER levels.The total and differential leukocyte counts of peripheral blood were measured.Demographic and potential metabolic confounding factors were analyzed with multiple correlation and logistic regressions to evaluate the effects of leukocyte counts on UAER.Results With the increase of UAER,the peripheral total leukocyte,neutrophil,monocyte,eosinophil and basophil counts increased.In contrast,the lymphocyte count decreased.The differences persisted even after adjusting the influence of age,sex,duration of diabetes and other known risk factors.Conclusions Our study shows that peripheral leukocyte counts,even within the normal range,are related with UAlb in subjects with type 2 diabetes in a dose-dependent manner.

Objective To compare the levels of serum high sensitivity C-reactive protein(hsC-RP) among subjects with normal fasting glucose plus normal glucose tolerance(NFG/NGT),IFG,IGT and IFG plus IGT,and to analyze the related risk factors. Methods 443 nondiabetic subjects aged 39-65 years were seperated into four groups:NFG plus NGT,IFG,IGT and IFG plus IGT.The serum hsC-RP levels and related factors were analyzed. Results Compared with IFG subjects,IGT subjects had higher hsC-RP levels.No differences in hsC-RP levels were found between NFG plus NGT group and IFG group, as well as between IGT group and IFG plus IGT group.Stepwise multiple regression showed that BMI and HOMA-IR were independent predictors of hsC-RP. Conclusions IGT subjects have significantly higher serum hsC-RP level than IFG subjetcts. The serum level of hsC-RP is associated with insulin resistance and the components numbers of metabolic syndrome.
