Lectin like oxidized low density lipoprotein receptor 1(LOX 1) is a type Ⅱ membrane protein belonging to the C type lectin family molecules which can act as a cell surface endocytosis receptor for oxidized LDL.LOX 1 can support binding, internalization and proteolytic degradation of oxidized LDL. And LOX 1 is involved in the platelet endothelium interaction and mediates phagocytosis of aged/apoptotic cells in endothelial cells ox LDL. Purification of soluble LOX 1 and the N terminal amino acid sequencing identified the two cleavage sites (Arg 86 Ser 87 and Lys 89 Ser 90 ). LOX 1 expression is not constitutive, but can be induced by proinflammatory stimuli, such as Angiotension Ⅱ, fluid shear stress and so on.

Objective To explore the ultrasound characteristics of carotid atherosclerosis in acute stroke patients with early neurological deterioration (END). Methods END was defined as a increase by at least two points in the National Institutes of Health Stroke Scale between admission and day 7. Among 128 patients with acute stroke in whom carotid ultrasound examinations were performed within 24 hours after admission, 38 patients with END and 40risk-matched patients without END were included in the END group and the non-END group,respectively. The ultrasound characteristics of carotid atherosclerosis were compared in both groups. Results Plaque score (16.7 ±4.4 mm vs. 13.3 ±3.5 mm, t=2.673, P=0.009),intima-media cross-sectional area (26. 4 ± 8. 5 mm2 vs. 20. 5 ± 6. 8 mm2, t = 3. 394, P =0. 001), arterial stiffness index (28. 94 ±4. 29 vs. 21. 22 ±5. 85, t = 6. 618, P =0. 000), and the rates of unstable plaque (66. 7% υs. 43. 3%, χ2=9. 164, P =0. 003), eccentric plaque (62. 8% vs. 45. 6%, χ2=5. 008, P =0. 025), stenosis ≥50% (71. 1% vs. 37. 5%, χ2=8. 828, P =0. 003), and negative remodeling (28. 9% vs. 7. 5%, χ2=6.087, P =0.014) in the END group were significantly higher than those in the non-END group, while the distensibility coefficient ([14. 74 ±8. 66]×10-6/P υs. [19. 16 ±9.35] × 10-6/Pa, t =2. 163, P=0. 034)and compliance coefficient ([0.49 ±0. 13] × 10-4 mm2/Pa υs. [0. 58 ±0. 11] × 10-4 mm2/Pa,t =3.307, P =0. 001) were significantly lower than those in the non-END group. Conclusions The ultrasound characteristics such as plaque score, intima-media cross-sectional area, arterial stiffness index, unstable plaque, eccentric plaque, stenosis ≥ 50%, negative remodeling,distensibility and compliance may be useful to predict END in patients with acute stroke.

Objective To compare and evaluate the clinical efficacy and side effect of vinorelbine plus gemcitabine and vinorelbine plus cisplatin combinations in advanced non-small-cell lung cancer(NSCLC). Methods 56 cases with non-treated advanced NSCLC were unrandomly divided into two groups: the GN group (27patients) treated with vinorelbine plus gemcitabine, the NP group (29 patients) treated with vinorelbine plus cisplatin,1/3 weeks×2～6 cycles. Results For the GN group, the overall response rate was 37.7 %, MTTP was 5.1months,one year survival rate (1-ySR) was 40.7 %. There were no significant difference in the response rates and the survival rates for the GN group compared with the NP group (P ＞0.05); But on the side effect of toxicities, WHO grade anemia and nausea/vomiting and tiredness of the GN group was significantly milder than the NP group (P ＜ 0.05). Conclusion Vinorelbine combined Gemcitabine regimen (GN) is active and well-tolerated. It is worth to investigate GN recommended as the first line chemotherapeutic regimen for the treatment of patients with advanced NSCLC.

Objective To investigate the effect of Tetramethylpyrazine (extracted from Chinese herbal medicine Ligusticum wallichii) employed in the early stage of severe brain injury on the restoration of brain function in coma patients monitored with digitized cerebral state monitor and clinical signs.Methods A total of 364 patients were referred to us from Emergency Department and Neurosurgery Department,Shenzhen People's Hospital from January 2006 through May 2012.The scores of patients'GlasgowPittsburgh coma scales were between 7-20 as brain injury happened within 24 h and survived more than two weeks.All patients were randomly (random number) divided into two groups:Tetramethylpyrazine group (n =186) and control group (n =178).The patients of control group received routine treatment,and the patients of Tetramethylpyrazine group were treated with Tetramethylpyrazine in addition to routine treatment in early stage.The patients of two groups were assessed with cerebral state indexes (CSI) and GlasgowPittsburgh coma scales before treatment and 3,7,14 days after treatment.Statistical comparisons between groups were analyzed by using repeated measure design analysis of variance.Results A repeated measures design analysis of variance indicated that the CSI and clinical signs (Glasgow-Pittsburgh coma scale) were improved significantly in Tetramethylpyrazine group than those in the control group at 3,7,14 days after treatment (P =0.024).Conclusions Tetramethylpyrazine can protect brain function and improve clinical signs in patients with severe brain injury in the early stage.

Objective:This study aims to evaluate the clinical effect and adverse reactions of oxaliplatin or irinotecan plus capecitabine treatment for colorectal liver metastases. Methods:Data from 125 cases of colorectal liver metastasis patients were continuously enrolled and randomized into two groups, i.e., 63 in group one (treatment group) and the other 62 in group two (the control group). Capecitabine was administered at 1 000 mg/m2 doses, twice a day from d1 to d14, to all patients. Irinotecan was administered at 150 mg/m2 in d1 to group one, and oxaliplatin was administered at 130 mg/m2 in d1 to group two. The drug administration cycle lasted for 21 days in both regimens, with at least 6 administration cycles. The total course was for 6 months at most. The therapeutic efficacy, median progression-free survival time, median survival time, short-term clinical effect, and adverse drug reaction were monthly determined. Results:The overall response rates and disease control rates were 33.3%and 66.7%in group one, respectively, and 35.5%and 70.9%in group two, respectively, with no significant differences between the groups (P>0.05). The median survival time and median progression-free survival time were 14 months and 5 months in group one, respectively, and 12 months and 5 months in group two, with no significant differences between the two groups (P>0.05). The level-Ⅲand-Ⅳadverse drug reactions mainly include hematological toxicity, gastrointestinal reactions, and hand-foot syndrome. The diarrhea frequency is obviously higher in group one than in group two, and the difference between the two groups is sta-tistically significant (P<0.05). No significant differences were observed in the other adverse reactions between the groups (P>0.05). Conclusion:The Oxaliplatin or Irinotecan plus Capecitabine treatment is effective for colorectal liver metastases, which enhances survival rate and reduces patient suffering because of it has less side effects and good tolerance. The treatment must be further generalized and clinically applied.
