Objective To investigate the relationship between plasma homocysteine levels and lipids in aged patients with acute cerebral infarction(ACI).Methods Fourty-eight cases(observation group),who had been inpatients with cerebral infarction during May 2006 to May 2007,thirty healthy people(control group)contrasted and analyzed.Results The mean plasma homocysteine level and cholesterol(TC),triglycerides(TG),low density lipoprotein(LDL)of aged patients with acute cereral infarction were significantly,higher than those of the control group,but high density lipoprotein(HDL)was lower(P＜0.01).No significant correlation between Hcy level and TC,TG,HDL-C,LDL-C level in serum.Conclusion Plasma homocysteine lexrel and lipids all siginificantly increased in aged patients with acute cereral infarction,and homocysteinemia is not related with lipids,but is an independent risk factor for cerebral infarction.

Objective To observe the effects and the functions of valsartan and simvastatin in early diabetic nephropathy. Methods A total of 80 patients with early diabetic nephropahy were randomly divided into two groups.The patients in control group(n=40)received valsartan at a dose of 80rag/day ,while in treated group(n=40)on the base of the same treatment as control group, added simvastatin 20 mg/everyrfight. To compare the differences of lipids,urine albumin excretion rate(UAER) and C-reactive protein(CRP) before or after treatments through 12 weeks. Re-sults The UAER of two groups decreased obviously after therapy,especially the treated group(P<0.01) ;the lipids and CRP also decreased evidently in the treated group (P<0.05). Conclusion The lipids, UAER, CRP of patients in early diabetic nephropathy could be down-regulated,with combined medication of the simvastatin and valsartan, and the injury of renal alleviated.

Objective To investigate the relationship between wheezing and serum levels of 25-hydroxyvitamin D3.Methods 130 children with lower respiratory tract infection were selected as the subjects, the children with wheezing in group A([Abstract] Objective To investigate the relationship between wheezing and serum levels of 25-hydroxyvitamin D3.Methods 130 children with lower respiratory tract infection were selected as the subjects, the children with wheezing in group A(n=70),normal pneumonia (no wheezing) were group B(n=60); The healthy children who were examined in the hospital at the same period were selected as the control group (n=60). The serum levels of 25-hydroxyvitamin D3 were measured by ELISA in the control and hospitalized children. The pathogens and allergens of the two groups were also detected. Results The levels of serum 25-hydroxyvitamin D3 in group A and group B were (56.92±16.88) nmol/L, (70.68±21.96) nmol/L, respectively, which was significantly lower than that in control group (82.69±17.63) nmol/L, ( t=8.50, 3.30,P=0.00,0.00); compared with group A( t=3.85, P=0.00). The positive rate of group A was 65.71%, which was significantly higher than that of group B (35.00%, χ2=12.20,P=0.00). The positive rate of group A was 30.00% compared with the control group (35.00%, χ2=0.36,P=0.54). The serum level of 25-hydroxyvitamin D3 was 75.57% in group A, which was significantly higher than that in group B (60.00%,χ2=14.21, P=0.00). The positive rate of virus detection was 57.14% in 98 children with serum 25-hydroxy vitamin D3 level<75 nmol/L, which was significantly higher than that in serum 25-hydroxy vitamin D3 level≥75 nmol/L(18.75%, χ2=14.25, P=0.00). The positive rate of allergens in serum 25-hydroxy vitamin D3 level <75 nmol/L was 35.71%, which was significantly higher than that in serum 25-hydroxy vitamin D3 level≥75 nmol/L(21.88%, χ2=2.11, P=0.14). Conclusion The main risk factor for children with wheezing is viral infection, while the low level of serum 25-hydroxy vitamin D3 in children increases the risk of viral infection, resulting in increased risk of wheezing in patients,so the clinical can occur through the detection of serum 25- hydroxyvitamin D3 levels to predict and intervention for children with wheezing.

Objective To assess the short-term effects and adverse reactions of combination regimen of gemcitabine, nedaplatin and paclitaxel for patients with metastatic cisplatin-resistant nasopharyngeal carcinoma (NPC). Methods A total of 15 patients with metastatic cisplatin-resistant NPC were enrolled. All patients were treated with a combination regimen including gemcitabine with 1000 mg/m2 on day 1st and 8th, nedaplatin with 70 mg/m2 on day 1st and paclitaxel with 135 mg/m2 on day 1st, repeated every 21 days. Response was evaluated according to Response Evaluation Criteria in Solid Tumors (RECIST) criteria 3.0. Results The overall response rate was 40.0 %, with a complete response rate of 6.7 % (1/15) and a partial response rate of 33.3 % (5/15). Six patients (40.0 %) had stable disease and 3 patients (20.0 %) had progressive disease. The median time to progression (TTP) was 4.7 months and the median overall survival was 6.3 months. Hematological toxicities were the adverse reaction with 40.0 % of leucopenia, 6.7 % of anemia and 20.0 % thrombocytopenia. One patient needed for platelet transfusion. Other adverse reactions were mild. Conclusion The combination regimen of gemcitabine, nedaplatin and paclitaxel is feasible as second-line chemotherapy in patients with metastatic cisplatin-resistant NPC.

To further uncover the scientific significance and molecular mechanism of the Chinese herbs with pungent hot or warm natures, endogenous and exogenous expression systems were established by isolation of dorsal root ganglion (DRG) neurons and transfection of HEK293 cells with TRPV1 channel gene separately. On this basis, the regulation action of capsaicin, one main ingredient from chili pepper, on TRPV1 channel was further explored by using confocal microscope. Besides, the three-sites one-unit technique and method were constructed based on the brown adipose tissue (BAT), anal and tail skin temperatures. Then the effect of capsaicin on mouse energy metabolism was evaluated. Both endogenous and exogenous TRPV1 channel could be activated and this action could be specifically blocked by the TRPV1 channel inhibitor capsazepine. Simultaneously, the mice's core body temperature and BAT temperature fall down and then go up, accompanied by the increase of temperature of the mice's tail skin. Promotion of the energy metabolism by activation of TRPV1 channel might be the common way for the pungent-hot (warm) herbs to demonstrate their natures.

Objective We examined the Grp78, ERK1/2 and phospho-ERK1/2 expressions in hepatocellular carcinoma(HCC) tissue samples in vitro, we interfered the expression of Grp78 in SMMC-7721 cells to explore whether Grp78 is involved in ERK1/2 signal pathway. Methods The Grp78, ERK1/2 and phospho-ERK1/2 expressions were detected by immunohistochemistry and confirmed by Western blotting in 47 HCC tissue samples. The Grp78 expression in SMMC-7721 cells was interfered by plasmid transfection and siRNA, ERK1/2 phosphorylation and expression were determined by Western blotting. Results The Grp78 expression was significantly correlated with ERK1/2 and phospho-ERK1/2 in HCC tissue samples. Overexpression of Grp78 promoted ERK1/2 phosphorylation in SMMC-7721 cells and the increased ERK1/2 phosphorylation was inhibited by Grp78 knockdown. Conclusion Grp78 is involved in the regulation of ERK1/2 signal pathway and might be a potential target for the comprehensive therapy of HCC.

Objective To investigate the effects of genistein on the mRNA expressions of collagen (Col), matrix metalloproteinase (MMP ) and tissue inhibitor of matrix metalloproteinase (TIMP) in human embryonic skin fibroblasts (CCC-ESF-1).MethodsThe cultured CCC-ESF-1cells were divided into a black control group, an estradiol group and genistein groups of different doses. The mRNA expressions of ColⅠ, ColⅢ , MMP-1, TIMP-1 and TIMP-2 were detected by RT-PCR.Results Compared with the black group, estradiol and medium dose of genistein (0.451 ± 0.037, 0.446 ± 0.047vs.0.385 ± 0.061, allP<0.05) could promote the proliferation of the CCC-ESF-1 cells, estradiol and medium dose of genistein could up-regulate the mRNA expressions of ColⅠ (0.960 ± 0.012, 0.929 ± 0.015vs.0.812 ± 0.014, allP<0.01), ColⅢ (0.892 ± 0.009, 0.824 ± 0.022vs.0.768 ± 0.025, allP<0.01), TIMP-1 (0.841 ± 0.023, 0.838 ± 0.053vs.0.751 ± 0.027, allP<0.01) and TIMP-2 (0.456 ± 0.017, 0.448 ± 0.036vs.0.381 ± 0.029, allP<0.01), and down-regulate MMP-1 mRNAexpression (0.398 ± 0.043, 0.402 ± 0.044vs.0.525 ± 0.006, allP<0.01).Conclusions Genistein could promote the proliferation of the CCC-ESF-1 cells, and that may be related with up-regulating the mRNA expressions of ColⅠ, ColⅢ , MMP-1, TIMP-1and down-regulating MMP-1 mRNA expression.
