Objective To study the enhancing effect of ultrasound plus microbubble on small interference RNA(siRNA)transfection in vitro and in vivo.Methods Human vascular epithelial growth factor(VEGF)siRNA with 2'deoxy modification(VEGF 2'-eoxy siRNA,VdsR)was used.The human CNE cells(fromnasopharyngeal carcinoma)line was used for in vitro cell-based experiments and in vivo mouse xenograft model.Two different microbubble agents.BR14 and Levovist.were used together with the RNA transfection reagent RNA-mate.ELISA and RT-PCR assays were used to assess VEGF gene expression.Immunohistochemical staining (IHC)was performed to assess CD31 expression in xenograft tumors.Results VdsR transfection in CNE cells abolished VEGF expression as determined by ELISA experiments.In the first mouse xenograft experiment,ultrasound exposure dramatically enhanced VdsR-mediated tumor inhibition.In the second mouse xenograft experiment,when VdsR was mixed with the microbubble reagents and then injected into xenografts,ultrasoundexposure significantly reduced tumor growth in BR14-mixed VdsR group but not in the Levovist-mixed VdsR group compared to the control.RT-PCR experiments demonstrated that VEGF expression in ultrasound-exposed tumors was significantly lower than that in the control.Meanwhile,VEGF expression in the tumor tissue treated by BRl4-mixed VdsR declined as compared with the controls.Tumor vascular density as measured by CD31 immunostaining was significantly decreased in ultrasound-exposed tumors compared to the control.Conclusions Ultrasound exposure and/or microbubble can significantly enhance delivery and the efficiency of VdsR-mediated anti-tumor effects,and should be a location-specific enhancement approach for siRNA-based anti-cancer therapy.

Andersson lesion is a destructive vertebral or disco-vertebral lesion that occurs in the late stage of the ankylosing spondylitis. According to the etiology, these lesions are usually classified into localized lesions and extensive lesions. The history of ankylosing spondylitis and characteristic imaging is the key to the diagnosis of Andersson lesion. Conservative treatment may be effective for localized lesions. However, surgical intervention is often required for the failure of conservative treatment and extensive lesions. Currently, the optimal procedure for this problem is spinal osteotomy through pseudarthrosis and debridement via posterior-only approach.

Aim To investigate the relationship between fibrinogen(FIB)and the progression of coronary plaque stenosis rate in patients with type 2 diabetes mellitus(T2DM).Methods Hospitalized T2DM patients who underwent two or more coronary CT angiography(CCTA)examinations in the First Affiliated Hospital of Xi'an Jiaotong U-niversity from January 2015 to December 2020 were included.The subjects were divided into high FIB and low FIB groups according to the median of FIB.The differences in the progression of coronary plaque stenosis rate and other clini-cal characteristics were compared between the two groups,and the relationship between FIB level and the progression of coronary plaque stenosis rate was analyzed by Spearman's correlation analysis and Logistic regression.Results A total of 145 patients were included,73 in the high FIB group and 72 in the low FIB group at baseline,with a median follow-up time of 25(18,40)months between CCTA.The age,proportion of women,and the progression of coronary plaque ste-nosis rate were higher in the high FIB group than those in the low FIB group,and the differences were statistically signifi-cant(P＜0.05).FIB level was positively correlated with the change in coronary plaque stenosis rate(r2=0.308,P＜0.001).Multivariate Logistic regression analysis showed that FIB level was a risk factor for the progression of coronary plaque stenosis rate in patients with T2DM(OR=5.25,95％CI:1.97～14.02,P＜0.001),after adjusting for age,sex and other clinical risk factors.Conclusion High baseline FIB level is an independent risk factor for the progression of coronary plaque stenosis rate in patients with T2DM,and monitoring FIB level is beneficial to cardiovascular risk stratifica-tion in patients with T2DM.

Objective:To establish a hypergravity loading model with a high-acceleration centrifugal loading device and to investigate the effects of different hypergravity loading and icariin on osteoblast adhesion and cytoskeleton.Methods:MC3T3-E1 cells were seeded in the dishes of cell culture at a density of 2×10 5/cm 2. And the experiment was divided into 6 groups: control group (without icariin and loading); simple administration group (only icariin); 10 G loading group (only loading); 10 G administration group (with icariin and loading); 40 G loading group (only loading); 40 G administration group (with icariin and loading). The experimental loading group was loaded with MC3T3-E1 cells using a high-acceleration centrifugal loader. And continuous loading for 3 d, 30 min per d. The control group and the simple administration group were exposed to normal gravity, and the remaining conditions were not different from the experimental group. Icariin was used at a concentration of 10 -7 mol/L in all administration groups, and the experiments were carried out according to the method of preventive administration. At the same time, the related molecular biological techniques such as alizarin red staining, alkaline phosphatase (ALP) activity measurement, CCK-8 cell proliferation experiment, cytoskeleton phalloidin staining, qPCR and Western Blot were used to detect the effects of icariin on osteoblasts adhesion protein integrin α5 and integrin β1 and cytoskeleton protein F-actin under hypergravity extreme mechanical environment. Results:All models were successfully prepared. The alizarin red staining: The icariin could significantly promote the formation of osteoblastic calcified nodules. And the 10 G loading could also promote the mineralization of osteoblasts and increase the number of mineralized nodules, while the mineralization and the number of mineralized nodules of osteoblasts are significantly reduced in 40 G loading. ALP activity test: The OD values of simple administration group, 10 G loading group and 40 G loading group were 0.246, 0.331 and 0.163, respectively. Compared with 0.207 in the control group, the differences were statistically significant ( P<0.05). The 10 G administration group and the 40 G administration group were 0.373 and 0.180, and the differences were statistically significant ( P<0.05). The results of CCK-8 proliferation experiments: The OD value of simple administration group were 0.650, which was statistically significant compared with 0.551 of control group ( P=0.031). The 10 G loading group and 40 G loading group were 1.193 and 0.245, and their differences with the control group were both statistically significant ( P<0.05). The OD value of 10G administration group and the 40 G administration group were 1.300 and 0.310, which were significantly different from the respective loading groups ( P<0.05). Phalloidin staining: 10 G loading significantly increased the number of cells, but the changes in cells morphology and skeleton were not obvious. 40 G loading significantly inhibited the increase of the number of cells, meanwhile, made the pseudopods of cells more shorter and even disappeared. 40 G loading made the seriously damage of the cytoskeleton and even cause the cells to death. Icariin had no effect on the cells morphology, but it did has a certain repair effect after the cells loading. The results of qPCR and Western Blot experiments all confirmed that the expressions of integrin α5, integrin β1 and F-actin were up-regulated after icariin treatment. 10 G loading could promote the expression of integrin α5, integrin β1 and F-actin, and 40 G loading significantly inhibited the expression of the mRNA and proteins. Conclusion:Both 10 G condition and icariin can promote the development, cell adhesion and the cytoskeleton's stability of osteoblasts, while 40 G has a significant inhibitory effect.

Objective: This study aimed to explore the role of SGK-1 in the occurrence of temporomandibular joint(TMJ) osteoarthritis(TMJ-OA). Methods: Sixteen rats were randomly divided into Control group(Control group) and TMJ-OA group(TMJ-OA group), and TMJ-OA group was injected with sodium iodoacetate(MIA) intra articular cavity while Control group was injected with 0.9% sodium chloride solution. Pain behavior was assessed by measuring the head withdrawal threshold(HWT) with a von-Frey apparatus. Hematoxylin-eosin(HE) and Safranin O-fast green stains were used to observe the histological structure changes of the condyle of TMJ-OA rats. Real-time PCR was performed to exam the expression levels of mRNA of SGK-1, MMP-13, IL-1β, COX-2 in mandibular condylar cartilage(MCC). HE stain was used to observe the histological structure changes of the trigeminal ganglion(TG) of TMJ-OA rats. Real-time PCR was performed to exam the expression levels of mRNA of SGK-1, COX-2 in TG. Results: MIA injection induced typical OA-like lesions in the TMJ within 28 days. Administration of MIA led to the significant decrease in HWT, disordered of the condyle cartilage and subchondral bone structure, demyelination aggravated of nerve fibers in TMJ rats. Compared with rats in Control groups, the expression levels of SGK-1 in MCC and TG of rats in TMJ-OA group were upregulated. Conclusion In the pathological process of TMJ-OA, SGK-1 may plays an important role not only in cartilage structural damage but also in pain transmission.
