OBJECTIVETo investigate the effect of Antrodia cinnamomea on gene expression related to aortal endothelial injury of rats with hyperlipidemia.

METHODFifty SD rats were randomly divided into five groups: the normal control group (NG), the model group (MG), the antrodia cinnamomea groups of low, middle and high doses (AC-LG, AC-MG, AC-HG, 250, 500, 1 000 mg x kg(-1)). The rats were fed with high-fat diets to establish the hyperlipidemia model. After the drug administration for 10 weeks, their serum lipid, SOD, MDA and ox-LDL, LOX-1, P38 MAPK and NF-kappaB mRNA and protein expression were respectively determined, and the aortal endothelial injury was observed under electron microscope.

RESULTIn the model group, the contents of TC, TG and LDL-C significant increased (P < 0.01), whereas the content of HDL-C significant decreased (P < 0.01). Compared with the model group, both the AC-M group and the AC-H group showed reduction in endothelial injury and significant decrease in the content of TC, TG and LDL-C (P < 0.05 or P < 0.01). The content of HDL-C increased, but with no significant difference. SOD activity in serum remarkably increased (P < 0.05 or P < 0.01), MDA and ox-LDL levels dramatically decreased (P < 0.05 or P < 0.01).

CONCLUSIONA. cinnamomea can alleviate endothelial lipid injury by inhibiting the expressions of LOX-1, P38MAPK and NF-kappaB in aorta and better protect aortal endothelial cells from oxidative lipid injury.

With new acupuncture and moxibustion as the study object, based on the basic composition of acupuncture-moxibustion theory, from 3 aspects of meridian-acupoint theory, acupuncture-moxibustion method theory and acupuncture-moxibustion treatment theory, under the background of western medicine, ZHU Lian's different opinions on theory and method of acupuncture and moxibustion were discussed. It was believed by ZHU Lian that the distribution of 14-meridians was approximately identical to that of nerves, so with modern neuroanatomy knowledge to understand the meaning of acupoint; the acupuncture function could be explained from the angle of neurophysiology. Clinical diagnosis and treatment method could be established by modern classification methods of diseases. ZHU Lian's cognition that was different from traditional theory and method of acupuncture and moxibustion was combined with updated physiology and anatomy knowledge at that time, and was involved with Pavlov's advanced nerve theory, so she firstly put forward the opinion that acupuncture therapy can't work without the involvement of cerebral cortex.

Objective:To investigate the effects of Nano-chitosan rhBMP-2 Gel(NCS/BMP-2 Gel)on the repair of mandibular de-fect.Methods:NCS/BMP-2 Gel and NCS Gel were prepared and respectively injected into the subcutaneous space on both sides of dorsum of 9 rats.3 rats were respectively sacrificed 10,20 and 30 d after injection.The subcutaneous nodules were histologicaly ex-amined.Mandibular defect was made in 54 SD rats and the rats were divided randomly and into 3 groups(n=18):NCS/BMP-2 Gel was implanted into the defects in group 1,NCS Gel in group 2,no injection in group 3.Animals were sacrificed 3,6 and 9 weeks after transplantation.X-ray examination,pathologic observation were conducted.Results:Subcutaneous nodules were found in both sides of the rat dorsum.The residual mandibular defect area in study group 1 was apparently smaller than that in group 2 and 3(P<0.05). More new bone formation was observed in the gel injected area in group 1 than in group 2 and 3.Conclusion:Nano-CS/BMP-2 Gel is biocompatible and can accelerate the healing of mandibular defect.

Objective To evaluate the diagnostic accuracy of contrast-enhanced MR angiography (CE MRA) in infrapopliteal occlusive diseases of diabetic patients.Methods A total of 105 patients with known diabetes and peripheral vascular occlusive disease who underwent both CE MRA and DSA examnations were included in this study.They had no obvious stenosis or with stenosis of less than 75％ in iliac,femoral,and popliteal arteries.Every infra-popliteal artery was anatomically divided into 9 vascular segments as tibiofibular trunk artery,proximal and distal anterior tibial artery,proximal and distal posterior tibial artery,proximal and distal peroneal artery,plantar and dorsalis pedis artery.There were 945 segments.The arterial stenosis was accessed with CE MRA and DSA respectively.The segments were scored in 5 categories as＜30％,≥30％ and＜50％,≥50％ and＜75％,≥75％ and＜100％,and 100％ according to stenostic degrees.The Kappa test was used to compare the diagnostic consistency of CE MRA and DSA.Taken DSA as a gold standard for reference,ROC curve was drawn to calculate the diagnostic accuracy of CE MRA in diagnosis of lower limb arterial disease.Results The ratio of statistically valid segments for both CE MRA and DSA were 97.7％ (923/945) in 945 vessel segments of 105 patients,and 390 of 923 arterial segments were both indicated as occlusion by CE MRA and DSA.The diagnostic consistency for the segments was listed in the decreasing order as follows:proximal peroneal artery,proximal posterior tibial artery,distal posterior tibial artery,proximal anterior tibial artery,distal anterior tibial artery,tibiofibular trunk artery,dorsalis pedis artery,plantar artery,distal peroneal artery,and corresponding Kappa values were 0.88,0.86,0.84,0.84,0.81,0.77,0.75,0.75 and 0.73,P＜ 0.05.The AUC(area under ROC curve) of CE MRA was 0.893 with 95％ confidence interval of 0.882 to 0.904.Conclusion CE MRA is an accurate imaging modality in the diagnosis of infrapopliteal occlusive disease s for diabetes.

BACKGROUND:Cel membrane microparticles CD31 and CD54 lead to microvascular injury in the femoral head by mediating vascular inflammatory response, promoting blood clotting, affecting vasomotion and promoting vascular endothelial injury. Studies have verified that membrane particles play an important role in steroid-induced necrosis of the femoral head, but there is no studies concerning relationship between microparticles and alcohol-induced avascular necrosis of femoral head. METHODS/DESIGN:This is a randomized control ed animal study. Healthy male Wistar rats wil be randomly assigned to two groups. In the model group, rats wil be intragastrical y administered hard liquor for 6 consecutive months to prepare models of alcohol-induced avascular necrosis of the femoral head. Blank controls wil be intragastrical y given an equal volume of physiological saline. In 1-6 months of intervention, six rats wil be randomly selected from each group every month. Blood wil be col ected separately. Flow cytometry wil be used to detect serum cel membrane particles CD31, CD54 levels. Bilateral femoral head wil be fixed, decalcified, embedded in wax, and then sections. After hematoxylin-eosin staining, empty bone lacuna wil be quantified under a light microscope to identify femoral head necrosis. Verhoff’s staining and MSB microthrombosis staining wil be used to observe microvascular injury and microvascular thrombosis in the femoral head, and to analyze the correlation of CD31 and CD54 levels with femoral head necrosis, vascular endothelial injury and microvascular thrombosis. DISCUSSION:This study wil investigate the effects of CD31 and CD54 on alcohol-induced avascular necrosis of the femoral head, explore the pathogenesis of alcohol-induced avascular necrosis of the femoral head, provide a new theoretical basis for early diagnosis and early treatment, and may provide a new target for its treatment. ETHICS APPROVAL:The protocol has been approved by the Animal Experimental Ethics Committee of Inner Mongolia Medical University (approval number YKD2016154). Experimental procedures and materials of rats wil be in accordance with the Guide for the Care and Use of Laboratory Animals, which is consistent with the guide of National Institutes of Health.

Objective To investigate the relationship between anti-HCV antibody level and hepatitis C virus genotype in the patients.Methods Total of 603 anti-HCV positive serum samples were collected during 2013 to 2014 by retrospective research method.HCV RNA were detected in anti-HCV positive samples by repeat test and the genotype were detected in HCV RNA positive samples.The distribution of anti-HCV level in different hepatitis C genotype patients was analyzed and the body's response to viral antibodies and viral genotype correlation with anti-HCV concentration interquartile range was explored.Rates among genotype groups were compared using chi-square test.Results Totally 412 of 603 (68.33％) samples were anti-HCV positive by double reagent screening.174(42.3％) samples were detected as HCV RNA positive.The distributions of different anti-HCV level in different genotype patients were 1a(n =8) 1/8,1/8,4/8,2/8;1b(n =112)25.9％ (29/112),17.0％ (19/112),25.9％ (29/112),31.3％ (35/112);2a(n =14)3/14,4/14,5/14,2/14;3a(n =11)3/11,6/11,2/11,0/11;3b(n =16)4/16,11/16,1/16,0/16;6a(n =8)2/8,2/8,1/8,3/8 with anti-HCV concentration interquartile range respectively.The anti-HCV concentration distribution was different in patients with different HCV genotypes.The anti-HCV concentration distribution in patients of 1 b,2a and 6a genotypes were evently,while anti-HCV level was relatively high in 1a (13.65) and relatively low in 3b (8.77).There were differences in different genotypes of antibody concentrations (x2 =35.2,P ＜ 0.05).Conclusions There was correlation between anti-HCV level and HCV genotype.Because there were fewer cases in some genotypes,it was necessary to investigate more samples to corfirm the above results.

BACKGROUND:The relationship between long-term heavy drinking and alcohol-induced necrosis of the femoral head has long been clear, but thepathogenesis of alcohol-induced necrosis of the femoral head is currently not fuly understood.
OBJECTIVE:To establish a rat model of alcohol-induced avascular necrosis of femoral head and to study its pathogenesis.
METHODS: Eighty Wistar rats were randomly divided into experimental and control groups (40 rats per group). Rats in the experimental group were intragastricaly administered strong wine 10 mL/kg, once a day, for 6 consecutive days. Rats in the control group were given physiological saline 10mL/kg, once a day, for 6 consecutive days. Bilateral femoral heads were randomly colected from six rats every month for histomorphological observation.
RESULTS AND CONCLUSION:(1) Osteonecrosis: in the experimental group, at 3 months, trabecular bone became thin, arranged disorderly, and the number of empty lacuna began to increase. At 6 months, typical osteonecrosis appeared, and vacant lacunaes increased significantly. In the control group, trabecular bone was complete and neatly arranged. Osteocytes were visible in bone lacuna, and normal morphology of cels was seen. (2) Injury of blood vessels: in the experimental group, at 3 months, micro-intimal hyperplasia was observed. Elastic fibers of partial vascular endothelium were reduced. Elastic fiber andmiddle-layer smooth muscle breakage and proliferation were found. At 6 months, above manifestations were more remarkable. In the control group, arteriole film was not thickened, and vessel wal was normal. (3) Formation of microthrombus, in the experimental group, the number of microthrombus was increased at 3 months, and became significant at 6 months. In the control group, the number of microthrombus was not altered. (4) Results indicated that chronic alcohol intake can lead to microvascular endothelial injury in the rat femoral head. Abnormal blood microcirculation was detected in local region, and resulted in avascular necrosis of the femoral head. The degree of necrosis was associated with alcohol intake.
