1.Lipoprotein lipase activity anti its relationship to serum lipid levels in elderly
Clinical Medicine of China 2008;24(8):775-777
Objective To evaluate lipoprotein lipase (LPL) activity and its relationship to serum lipid. Methods Serum triglyceride (TG) ,total cholesterol (TC), low density lipoprotein cholesterol (LDL-C), high density lipoprotein cholesterol (HDL-C) and postheparin LPL activity in 40 elderly subjects and 45 subjects in control group. Results TG,TC and LDL-C levels were much higher in the elderly than in control group (P <0.05 orP <0.01) ;postheparin LPL activity was lower in elderly (P <0.05) ; and showed a negative correlation with serum TG level (r = -0. 513 ,P < 0.01), but was positively correlated with serum HDL-C concentration (r = 0. 390, P < 0.05). Conclusion The decreased activity of LPL in the elderly may contribute to hypertriglyceridemia associated with low level of high density lipoprotein cholesterol, and could be a risk factor for atherosclerosis.

Background and purpose:It has been shown that chemotherapy could improve the quality of life and prolongation of survival time of the patients with advanced gastric cancer. There is still no standard chemotherapy regimen for advanced and metastatic gastric cancer, and regimens with high efficacy and safety are scare. Toxicities are considered to be limiting factors and in? uence the quality of life in the patients with advanced gastric cancer. The purpose of this study was to investigate the effi cacy and toxicity of docetaxel(DOC) in combination with oxaliplatin(OXA) as fi rst-line treatment in advanced gastric cancer and try to fi nd a regimen that would be more tolerable without deterioration of treatment response. Methods:48 patients with advanced gastric cancer were treated with docetaxel 35 mg/m2, ivgtt, d1,d8 combined with oxaliplatin 130 mg/ m2,ivgtt,d1 ;repeated every 3 weeks (one cycle) ,The effect was evaluated after two cycles. The effi cacy and toxicity were evaluated according to WHO standard. Results:48 patients could be evaluated for clinical response. Complete response in 3 pts and partial response in 24 pts were observed with an overall response rate of 56.25%, median time to progression (MTTP) was 5.6 months and median overall survival (MST) was 11.8 months. The most common toxicities were bone marrow suppression, peripheral neuritis, nausea and vomiting. All of them are reversible. Conclusion:Combining weekly docetaxel and oxaliplatin is an effective and well tolerated alternative treatment in advanced gastric cancer and has yielded promising results.

Objective: To investigate the effect of miR-144-3p modulating proliferation, migration and apoptosis of liver cancer Huh-7 cells through blocking frizzled class receptor 4 (FZD4)/Wnt/β-catenin pathway and the possible mechanism. Methods: A total of 18 pairs of cancer tissues and corresponding para-cancerous tissues from liver cancer patients, who underwent surgery in Workers' Hospital of Liuzhou City from March 2012 to July 2017, were collected for this study; in addition, hepatic cancer cell lines (Huh-7, SMMC7721 and MHCC97) and human normal liver epithelial cell line THLE-3 were also collected. The expression of miR-144-3p in liver cancer tissues and cell lines was detected by qPCR. MiR-144-3p mimics/inhibitor and FZD4 siRNA were transfected into liver cancer Huh-7 cells; the proliferation, migration and apoptosis of Huh-7 cells were evaluated by CCK-8 assay, Transwell assay, wound healing assay and Annexin V-FITC/PI double staining flow cytometry assay, respectively. The interaction between miR-144-3p and FZD4 was verified by dual-luciferase reporter gene assay. Results: The expression of miR-144-3p was down-regulated in liver cancer tissues and cell lines (P<0.05 or P<0.01). Over-expression of miR-144-3p significantly inhibited cell proliferation viability, migration but induced apoptosis of Huh-7 cells (all P<0.01). Moreover, dual-luciferase reporter gene assay showed that miR-144-3p directly interacted with FZD4 and suppressed its expression. Furthermore, in vitro experiments verified that miR-144-3p targeted FZD4 to suppress the proliferation, migration and promote apoptosis of Huh-7 cells via blocking Wnt/β-catenin pathway (all P<0.01). Conclusion: miR-144-3p inhibits malignant biological behaviors of liver cancer Huh-7 cells via blocking Wnt/FZD4/β-catenin signaling pathway, which may provide potential molecular targets for early diagnosis or treatment of liver cancer.

Objective To study the effect of scan position consistency on computer tomography-magnetic resonance (CT-MR) images automatic registration in patients with nasopharyngeal carcinoma.Methods Fifteen patients with nasopharyngeal carcinoma were enrolled in this study and scanned with the same position to acquire CT images and MR-1 images. Then they were reacanned with different position for MR-2 images. Image registration of CT-MR-1 and CT-MR-2 was finished using mutual information method.The registration errors were evaluated by measuring the distances between marks. Results The error of au-tomatic CT-MR registration with consistent scan position was 1.32 nun, comparing with the minimum of 2.00 ram and the maximum of 3.83 mm with different positions. Conclusion Keeping consistent scan position can improve the accuracy of image registration.

Objective:To compare the adverse reactions of concurrent chemoradiotherapy with docetaxel versus those of sequential and scheduled adjuvant therapy after a modified radical mastectomy in locally advanced breast cancer. Additionally, this work aims to evaluate the safety and feasibility of a synchronous therapy schedule. Methods:A total of 155 female breast cancer patients in the Fourth Affiliated Hospital of Guangxi Medical University were enrol ed from January 2009 to December 2014. Al the patients were diagnosed with infiltrating ductal carcinoma and stage pT3-4, pN1-3c M0, or pAnyTpN2-3cM0 after modified radical mastectomy. After completing the fluorouracil+epirubicin+cyclophosphamide adjuvant chemotherapy, all the patients were randomly divided into two groups by using the method of sealed envelopes. The synchronous group, which received synchronous chemoradiotherapy with docetaxel, comprised 78 cases. The sequential group, which received radiotherapy fol owing docetaxel chemotherapy, comprised 77 cases. The clinical toxic reactions and effects in both groups were assessed after all schedules. Results:A median follow-up period of 39 (16-62) months showed that the radiation side effects of the synchronous and sequential groups were mild. No patients with 3-4 grade radiation-induced skin reactions or symptoms of heart and lung radiation side effects were reported. The rate of 1-2 grade radiation-induced skin reactions was 89.7%(70/78) in the synchronous group and 88.3%(68/77) in the sequential group, but the difference was not statistically significant (P>0.05). The three-year recurrence-free survival rate was 92.3%(72/78) in the synchronous group and 81.8%(63/77) in the sequential group, and the difference was statistically significant (P=0.046). Conclusion:Synchronous chemoradiotherapy with docetaxel as adjuvant therapy exhibited mild and tolerable adverse reactions fol owing modified radical mastectomy in local y advanced breast cancer. Compared with the sequential schedule, the synchronous schedule showed a significantly increased three-year recurrence-free survival rate. Therefore, a synchronous chemo-radiotherapy schedule is safe and feasible and can be used as a treatment option for locally advanced breast cancer.
