BACKGROUND: Angiogenesis in atherosclerotic plaque occurred on the basis of atherosclerotic lesions, and the new formed blood vessels promoted the development of angiogenesis. Soluble vascular endothelial growth factor receptor 1 (sFlt-1) gene transfection reduces neointimal formation after vascular injury in rabbits, also reduces early vascular inflammation and proliferation, and the formation of neointima lately.
OBJECTIVE: To observe the effects of highly expressed sFlt-1 on atherosclerotic plaque.
METHODS: A total of 48 male New Zealand rabbits were divided into four groups randomly: normal control group (n=8), sham operation group (n=8), bal oon injury+high lipid diet+pEGFP-N1 group (n=16) and bal oon injury+high lipid diet+pEGFP-N1-sFlt-1 group (n=16). Normal control group and sham operation group were supplied with normal diet. Bal oon injury+high lipid diet+pEGFP-N1 group and bal oon injury+high lipid diet+pEGFP-N1-sFlt-1 group were supplied with high lipid diet and injured by bal oon 2 weeks later. Bal oon injury+high lipid diet+pEGFP-N1 group was transfected with pEGFP-N1 and bal oon injury+high lipid diet+pEGFP-N1-sFlt-1 group was transfected with pEGFP-N1-sFlt-1.
RESULTS AND CONCLUSION: In the bal oon injury+high lipid diet+pEGFP-N1 group and bal oon injury+high lipid diet+pEGFP-N1-sFlt-1 group, blood lipid levels apparently increased. At 3 days after model establishment, sFlt-1 expression levels noticeably increased, and atherosclerotic plaque formed to different degrees. Plaque area, plaque perimeter, plaque maximum thickness and the number of positive-cel s within the plaque were significantly less in the bal oon injury+high lipid diet+pEGFP-N1-sFlt-1 group than in the bal oon injury+high lipid diet+pEGFP-N1 group. These results confirm that sFlt-1 gene may express effectively in iliac artery wal of rabbit, inhibited the formation of atherosclerotic plaque and delayed the development of atherosclerotic plaque.

The antifungal mechanism of the TS67(Penicillum sp.) producing bioactive metabolites was investigated in this paper. The test indicated that mycelia growth, spores forming and spores germination of Bipolaris maydis and Fusarium oxysporum can be inhibitied by metabolites, after 50% fermentation broth acting 120 hours, the inhibition rate of hyphal growth can reach about 77.78%, 70.30%, the inhibition rate of spores forming also arrived at 58.8%, 73.5%; under 50% fermentation broth acting 12 hours, the inhibition rate of spores germination were up to 78.3%, 62.0%, the mycelia under activity metabolites conditoins also showed surface nodulation and growing point expanding irregularly, protoplasmic condesing, etc. Based on all these results, we may draw a conclusion that activity metabolites maybe target at fungal cell wall.

Objective To evaluate the vestibular function in patients with cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL). Methods Seventeen CADASIL patients were recruited in the present study and 17 healthy volunteers served as control subjects. Electronystagmogram examinations including gaze nystagmus test, spontaneous nystagmus test, saccade test, pursuit test, optokinetic nystagmus test and caloric test were performed in the subjects. Results Neither patients nor controls had gaze nystagmus or spontaneous nystagmus. There was no difference in the latency and velocity of saccade movement between patients and controls. The accuracy of the saccade movement, the accuracy in leftward saccade, was significantly lower in CADASIL group compared with controls. The pursuit movement gains was also significantly lower in CADASIL group than in control group(G_L:0.79±0.08, G_R:0.76±0.12)(t=-3.739、-2.911,P <0.05) compared with controls(G_L:0.87±0.04, G_R:0.86±0.06).The optokinetic nystagmus gains were significantly decreased in CADASIL group(G_L:0.79±0.17,G_R:0.78±0.18)(t=-2.342、-2.335,P<0.05) compared with controls(G_L:0.90±0.08,G_R:0.89±0.09). The caloric test was performed in one CADASIL patient and the result revealed an incomplete fixing inhibition. CADASIL group was further divided into normal subgroup and abnormal subgroup based on the pursuit curve. The comparison between those two subgroups demonstrated a significant correlation between the pursuit movement and the symptoms of vertigo or dizziness(P<0.05). Conclusions The central vestibular function is impaired in CADASIL patients and the abnormal vestibular function is related to the symptom of vertigo or dizziness in CADASIL patients.

Abstract? AIM: To analyze the ocular manifestations of meningiomas in the trigone of the lateral ventricle, discuss the relevant factors of visual impairment in these patients and things need attention clinically.?METHODS:Retrospectively study on the clinical data of 90 eyes in 45 patients diagnosed of trigonal meningiomas treated at Beijing Tian Tan Hospital from October 2011 to October 2015.Preoperative examinations including visual acuity, optic disc findings, visual field, size of tumors and other change in MRI were analyzed.?RESULTS: Patients'age was 12-68 years old ( mean 41.7 ±13.7 years ). Male/female ratio was 1 ∶4.6. Decreased visual acuity occurred in 18 eyes.Optic disc edema was found in 24 eyes and optic disc pale in 6 eyes. Fourty -seven eyes had visual field defect, mostly homonymous hemianopia or defect. The maximum diameter of tumors was 2.1-9.6cm (4.8±1.7cm).Range of tumor volume was 3.02-193.2cm3(48.3±47.8cm3).A positive correlation of preoperative visual field defect was found with tumor volume, tumor maximum diameter, and brain midline shift respectively. While the preoperative visual field defect was not found any correlation with age, gender, course, and the enlargement of the ventricle and the edema of the tissue around the tumors. After Mann-Whitney U test, the differences on tumor volume, the maximum diameter of tumors, and brain midline shift between the two groups were significant.? CONCLUSION: Patients with trigonal meningiomas often have ocular signs and symptoms.The major reason of visual field defect is the damage of optic radiation around the tumor.The specific position of injured optic radiation determines the type and extent of visual field defect.Both ophthalmologist and neurosurgeon should pay attention to tumors nearby posterior visual pathway. Doing neurophthalmology examinations for these patients and realizing the position between the tumor and posterior visual pathway will be helpful and necessary in surgical planning.

Objective:To analyze the distribution of UGT1A1 gene polymorphisms in Chinese Han patients with extensive-disease small cell lung cancer(ED-SCLC),and evaluate the correlation between UGT1A1 gene polymorphisms and toxicity and efficacy of irino-tecan(CPT-11) based regimen in the patients with ED-SCLC. Methods: The analysis of UGT1A1?28 and UGT1A1?6 gene poly-morphisms was performed in 67 patients with ED-SCLC admitted in our hospital from June 2011 to January 2013. The 67 cases with ED-SCLC treated with irinotecan(CPT-11) based regimen were enrolled to observe the adverse events and efficacy during the chemo-therapy, including objective responserate rate ( ORR) , progression free survival ( PFS) and overall survival ( OS) . The incidence of different genotypes was compared. Results:The distribution of UGT1A1 genotypes in the 67 patients was follows:UGT1A1?28 wild-type (WT) genotype TA6/6 (56, 83. 6%), heterozygous genotype TA6/7 (11, 16. 4%);UGT1A1?6 wild-type (WT) genotype G/G (45,67. 2%), heterozygous genotype G/A (22,32. 8%). No significant difference of PFS and OS was observed between the differ-ent genotypes. The incidence of grade 3 and 4 delayed diarrhea and neutropenia in the patients carrying UGT1A1?6 G/A was higher than that in those with WT genotype (36. 4% vs. 6. 6%, P<0. 05;27. 2% vs. 4. 4%, P<0. 05, respectively). The incidence of grade 3 and 4 thrombocytopenia in the patients carrying UGT1A1?28 TA6/7 was higher than that in those with WT genotype (27. 2%vs. 1. 8%, P<0. 05). The patients simultaneously carrying UGT1A1?28 TA6/7 and UGT1A1?6 G/A were prone to suffering 3 and 4 delayed diarrhea and neutropenia. Conclusion: UGT1A1 polymorphisms may predict the adverse events of CPT-11 in ED-SCLC, while can not predict the efficacy of CPT-11.
