Objective To evaluate the effects of pregabalin combined with hydrochloric oxycodone on patients with ma-lignant neuropathic pain (MNP). Methods A total of 66 patients with MNP was divided into control group or treatment group randomly. The patients in control group received only hydrochloric oxycodone, and treatment group were treated with the combina-tion of pregabalin and hydrochloric oxycodone. Numeric rating scale (NRS) score was used to evaluate the analgesic effects. Med-ical outcomes study sleep scale (MOS-SS,Chinese version) was used to evaluate the improvement of sleep disorder. The changes of depression or anxiety were investigated by 17-item Hamilton Depression Rating Scale (HAMD-17) or Hamilton Anxiety Scale (HAMA), respectively. Side effects were accessed by Acute and Subacute Toxicity Grading Criteria of Anticancer Drugs (WHO). Results The pain control rate of treatment group was 87. 1% , which was superior to that of control group (58. 6% ) (P<0. 05). The improvement of sleep interference, and the quality and quantity of sleep in treatment group were also superior to that in control group (P<0. 05). After the treatment, depression and anxiety was attenuated in both groups, and the improvement degree in treatment group was higher than that in control group (P<0. 05). No obvious side effects were found in either groups. Conclusion The combination therapy of pregabalin and hydrochloric oxycodone is the better way to treat MNP.

Objective To investigate the effect and potential mechanism of PSRC1 overexpression on foam cell formation of oxidized low-density lipoprotein(ox-LDL)-induced RAW264.7. Method After 48-h treat-ment of 100 μg/ml ox-LDL,changes of the accumulation of cholesterol esters in two groups was detected by oil red O staining.The protein expression of SR-AⅠand LDLR was detected by Western blot assay.Besides,ELISA was used to detect levels of IL-6 and TNF-α.Result The accumulation of cholesterol esters was lower in Ad-PSRC1 group than that in Ad-GFP group(P<0.05). The protein expression of SR-AⅠand LDLR was decreased signifi-cantly(P<0.05),and levels of the secreted IL-6 and TNF-α were also significantly decreased(P<0.05).Con-clusion Our data indicates that PSRC1 overexpression suppresses the formation of foam cells through improving lipid metabolism and down-regulating inflammatory cytokine IL-6 and TNF-α in macrophages.

Objective The study was to analyze the relationship between HDL particles,the level of HDL-C and the concordance of HDL-C and apoA-Ⅰand the degree of coronary stenosis,then to explore their values in predicting coronary artery disease.Methods 591 patients were collected for coronary angiography,and calculated Gensini score respectively.HDL particles and the level of HDL-C,apoA-Ⅰwere analyzed in coronary artery disease (CAD)group and non-CAD group,stable angina pectoris(SAP)group and acute coronary syndrome(ACS)group and four groups divided by quartile of Gensini score(A,B,C,D).To investigate the relationship between the con-cordance of HDL-C and apoA-Ⅰand the severity of coronary artery disease,HDL-C,apoA-Ⅰwere divided into low and high group according to the 50 percentile,then pair wise combination was done into four groups. Results Compared with non-CAD group,HDL particles,the level of HDL-C,apoA-Ⅰwere significantly reduced in CAD group(P<0.001).Compared with SAP group,similar results were found in ACS group.HDL particles,the level of HDL-C,apoA-Ⅰwere decreased gradually in A,B,C,D group(P<0.001).The concordance of HDL-C and apoA-Ⅰwas related to the risk of CAD(P<0.001).The area under curve(AUC)of HDL particles was higher than that of HDL-C,the concordance of HDL-C and apoA-Ⅰ.Conclusions HDL particles,HDL-C,the concordance of HDL-C and apoA-Ⅰwere related to coronary stenosis.The value of HDL particles in predicting CAD risk was su-perior to that of HDL-C,the concordance of HDL-C and apoA-Ⅰ.

OBJECTIVE: To analyze the correlation of lipoprotein(a) [Lp(a)] with the clinical stability and severity of coronary artery stenosis in patients with coronary artery disease (CAD). METHODS: A total of 531 patients undergoing coronary angiography in Nanfang Hospital between January, 2013 and December, 2016 were enrolled in this study. At the cutoff Lp(a) concentration of 300 mg/L, the patients were divided into high Lp(a) group (=191) and low Lp(a) group (=340). In each group, the patients with an established diagnosis of CAD based on coronary angiography findings were further divided into stable angina pectoris (SAP) group and acute coronary syndrome (ACS) group. The correlation between the severity of coronary artery stenosis and Lp(a) was evaluated. RESULTS: The patients in high and low Lp(a) groups showed no significant differences in age, gender, body mass index, smoking status, hypertension, or diabetes (>0.05). Multivariate logistic regression analysis revealed that age, gender, and serum levels of low-density lipoprotein cholesterol (LDL-C) and Lp(a) were independent risk factors for CAD in these patients. A high Lp(a) level was associated with an increased risk of CAD (OR=2.443, 95%CI: 1.205-4.951, =0.013). The patients with a high Lp(a) level were at a significantly higher risk of CAD than those with a low Lp(a) level irrespective of a low or high level of LDL-C (=0.006 and 0.020). In the patients with CAD, the ACS group had a significantly higher Lp(a) level than the SAP group ( < 0.001); the proportion of the patients with high Gensini scores was significantly greater in high Lp(a) group than in low Lp(a) group (17.3% vs 5.6%, =0.026), and a linear relationship was found between Lp(a) level and Gensini score (R=0.130, =0.006). CONCLUSIONS Serum level of Lp(a) is an independent risk factor for CAD, and an increased Lp(a) is the residual risk for CAD. In patients with CAD, a high Lp(a) level is associated with the clinical instability and severity of coronary artery stenosis.

Chronic inflammation results from excessive pro-inflammatory signaling and the failure to resolve the inflammatory reaction. Lipid mediators orchestrate both the initiation and resolution of inflammation. Switching from pro-inflammatory to pro-resolving lipid mediator biosynthesis is considered as efficient strategy to relieve chronic inflammation, though drug candidates exhibiting such features are unknown. Starting from a library of Vietnamese medical plant extracts, we identified isomers of the biflavanoid 8-methylsocotrin-4'-ol from
