OBJECTIVETo study the effect of Buyang Huanwu Decoction (BHD), Xuefu Zhuyu Decoction (XZD), and Sijunzi Decoction (SD) contained serums on expressions of Toll-like receptor 4 (TLR4)/nuclear factor (NF)-κB signals, lectin-like oxidized low-density lipoprotein receptor-1 (LOX-1), tumor necrosis factor-α (TNF-α), vascular cell adhesion molecule-1 (VCAM-1), intercellular adhesion molecule-1 (ICAM-1), and to explore possible anti-atherosclerotic mechanisms.

METHODSTwenty New Zealand rabbits were divided into 4 groups at random, i.e., the normal control group, the BHD group (6.7 g/kg), the XZD group (3.6 g/kg), and the SD group (1.6 g/kg), 5 in each group. All medication lasted for 7 successive days. Two h after the final medication, about 50 mL blood was withdrawn from rabbit heart for preparing serums. Human umbilical vein endothelial cell ECV304 were cultured in vitro for 18 h and randomly divided into the blank control group, the model group, the Western medicine (WM) control group, the BHD group, the XZD group, and the SD group at random. ECV304, except in the blank control group, were stimulated with lipopolysaccharide (LPS) for 2 h. Those in the WM control group and CM groups were treated respectively with corresponding CM contained serum for 24 h. Finally gene and protein expressions of TLR4, myeloid differentiation factor 88 (MyD88), tumor necrosis factor receptor-associated factor-6 (TRAF-6), NF-κB, LOX-1, TNF-α, ICAM-1, and VCAM-1 were detected by fluorescent quantitative PCR and Western blot.

RESULTSCompared with the blank control group, mRNA expressions of TLR4, MyD88, TRAF-6, NF-KB, LOX-1 , TNF-cx, ICAM-1, and VCAM-1 increased significantly; protein expressions of TLR4, NF-κB, LOX-1, TNF-α, ICAM-1, and VCAM-1 also increased significantly in the model group (P < 0.01). Compared with the model group, mRNA and protein expressions of each index could be significantly inhibited in the BHD group, the XZD group, and the WM control group (P < 0.05). Besides, mRNA and protein expressions of each index could be significantly elevated more in the BHD group and the XZD group than in the WM control group (P < 0.05). No statistical difference existed in each index between the SD group and the rest groups (P > 0.05).

CONCLUSIONSThe mechanism of BHD and XZD for fighting against atherosclerosis might be associated with inhibiting TLR4/NF-κB signal transduction pathway and expressions of its downstream inflammatory factors such as LOX-1, TNF-α, ICAM-1, and VCAM-1. But SD showed no associated effect on atherosclerosis.

Objective To study the application of magnetic resonance T2 -mapping and diffusion weighted imaging(DWI)in diagnosis of early cartilage degeneration of the knee joint.Methods 56 patients with clinical intends to diagnosis of early osteoarthritis of the knee were set as observation group,another 56 healthy volunteers were selected as healthy control group.The subjects of the two groups were given knee MRI T2 mapping and DWI,the T2 acquisition value and ADC value of the two groups were analyzed and compared.Results In the observation group, the side of the femoral (37.18 ±4.09),lateral tibial (32.16 ±2.75)and hip (34.56 ±4.21)were significantly lower than those in the healthy control group[femoral side (49.87 ±5.02),tibial side (47.34 ±5.01),hip surface (51.23 ±5.19)](t =20.16,18.36,23.65,all P <0.05).Conclusion Magnetic resonance T2 -mapping and DWI imaging can be found in the early knee cartilage degeneration,can lead to the rise of T2 and ADC value,so there is no cartilage damage to the cartilage damage.

Objective To explore the clinical features, treatment and prognosis of intrabepatic biliary cystadenocarcinoma (IBC). Methods We retrospectively analyzed clinical data of 17 patients with pathologically confirmed IBC, treated between January 2002 and September 2007. Results Of the 17 patients, 4 were men and 13 were women, with a mean age of 49.3 years (range 45 -68). Serum level of AFP was normal in all patients. CA19-9 was abnormally elevated in only two patients and the other two had abnormal serum level of CEA. Seven cases underwent radical resection, 7 underwent complete tumor resection combined with removal of tumor thrombi in the bile duct, 3 received palliative surgery. On histopathological examination, 10 were biliary cystadenocarcinoma,2 were biliary cystadenoma with partial eanceration,2 were papillary cystadenocarcinoma,2 were mutinous papillary cystadenocarcinoma and 1 was of mixed cystadenocarcinoma and hepatocellular carcinoma. According to tumor differentiation, the number of well, moderate and poor-differentiated group was 7, 3 and 7 cases respectively. The medality of surgery (β= - 0.692, P = 0.01) and tumor differentiation (β = - 2.041, P = 0.007) effected the prognosis significantly. Conclusions IBC occurs mainly in elderly women. CA19-9 examination does not help in the establishment of diagnosis of IBC. The occurrence of tumor thrombosis in common bile duct doesn't necessarily indicate poor prognosis, hence a IBC patient will still have a satisfactory prognosis should the primary tumor be completely resected and tumor thrombi removed.

Objective To evaluate the clinical application of multi-slice spiral CT(MSCT) and X-ray plain film in congenital scoliosis.Methods 40 cases with congenital scoliosis were undergone MSCT scan,the imaging data were reconstructed with maximum intensity projection(MIP),multiple planar reconstruction(MPR),surface shaded display(SSD) and surface volume rendering(SVR),the applied value of these various reconstructed images were analysed comparatively with X-ray plain film.Results Based on the preoperative X-ray plain films,the spinal formation failure,segmentation failure and mixed failure of spine were found in 18,15 and 7 cases respecitvely.However MSCT scan showed that 13 cases had formation failure,12 cases had segmentation failure and 15 cases were mixed failure of spine,and in combination with spinal bifida in 6,rib deformity in 8 and bony ridge inside vertebral canal in 4.The relative features of congenital scoliosis could be comprehensively evaluated by SVR images.Conclusion The reformatted images of MSCT is remarkedly superior to conventional X-ray images in judging the classification and area of spinal deformity accurately.

Objective To explore a modified technique of perforator flap anatomical study,in an attempt to understand the vascular territory of the specific perforator vessel in flaps,and determined its application in posterior tibial artery perforator flaps.Methods From October,2013 to October,2014,6 corpse were used in this study.A full-thickness posterior tibial artery perforator flap was excised from the crus of a fresh adult corpse.The anatomical measurements were synchronized with the procedure.The isolated skin flaps were fixed in a frame made of silk screen and batten and subsequently photographed.In vitro skin flaps were divided into 3 groups:full-thickness,without deep fascia,and without subcutaneous adipose layer.The skin flaps were perfused with barium sulfate silicone,and photographed using mammography after coagulation of the silicone.The imaging data were processed by digital software system.Results The mean number of posterior tibial artery perforators in the lower medial leg was 4.17 ± 0.94.The projection points of perforated sites were located in the area 2-3 cm lateral to the A-C line.The proximal border was (4.51 ± 1.84)cm distal to the plane of tibial medial condyle;the distal border reached the medial malleolus plane;and the anterior and posterior borders reaching the anterior and posterior midline of the crus respectively.And according to the comparison of the 3 group processed images,vascular territory change could be obtained.And this could provid clinicians with reliable anatomical information,guiding the acquisition and trimming of perforator flaps.Conclusion The modified strategy intuitively indicated the blood vascular areas of different artery perforator flaps of varying thickness and the vascular branches as well as their courses.The approach is profoundly significant in guiding the acquisition of skin flaps and for the trimming and reconstruction of flaps.The deep fascia of posterior tibial artery perforator flaps plays a negligible role in the blood supply of flaps.Furthermore,the subcutaneous adipose tissues in the distal portion of flaps can be thinned appropriately,with limited vascular consequences.
