Objective To develop and validate a ultrasonographic (US)imaging agent with targeted microbubbles that attaches to chemokine receptor 2 (CCR2)and to compare the US single obtained from targeted microbubble with that from control microbubble in murine breast tumor model.Methods The microbubble which carried CCR2 antibody (MBCCR2 )and isotype-macthed immunoglobulin G-labled control microbubble (MBcontrol ) were prepared. The microbubble size and distribution were assessed by AccuSizer780.Binding specificities of targeted microbubble compared with control microbubble were tested with murine microvascular endothelial cells (bEnd.3 ).Orthotopic breast tumor model was estabished in BALB/c mice with mouse breast cancer 4T1 cell.In vivo imaging signals of contrast material-enhanced ultrasound by use these two different types of microbubble which were injected respectively into each mouse at random order and 30 min interval.Tumor tissue was stained for CCR2 and CD3 1 .Results Automatic Particle Sizer showed size uniform of two kinds of microbubbles,and narrow distribution of particle size (mean diameter of about 1 -2 μm),which were not significantly different (P >0.05).Adhension to bEnd. 3 endothelial cells was significantly higher (P < 0.001 )for MBCCR2 (mean,9.50 ± 1 .5 1 )than that for MBcontrol (mean,0.01 ±0.01).Imaging signal in the murine tumor model was significantly higher for MBCCR2 [mean,(6.76±0.26)dB]than that for MBcontrol [mean,(1 .06 ±0.62)dB,P <0.001 ].Immunofluorescence confirmed expression of CCR2 on tumor vasculature.Conclusions The targeted microbubbles with CCR2 monoclonal antibody had been successfully prepared,which precisely targeted to CCR2 of tumor angiogenesis in the murine breast cancer xenograft tumor models in vivo.These results suggest that the targeted microbubbles as a kind of ultrasound molecular imaging agent with a better specificity can be used for both evaluating tumor neovascularization and monitoring therapeutic effect of anti-angiogenesis.

Objective To evaluate the effect of dexmedetomidine on the expression of c-fos protein in the dorsal root ganglion neurons in a rat model of neuropathic pain (NP).Methods Seventy-two adult male SpragueDawley rats,weighing 180-240 g,were randomly divided into 3 groups (n =24 each) using a random number table:sham operation group (group S),group NP,and dexmedetomidine group (group Dex).The animals were anesthetized with intraperitoneal 10％ chloral hydrate 350 mg/kg.The right sciatic nerve was exposed and 4 loose ligatures were placed on the sciatic nerve at 1 mm intervals with 4-0 silk thread in NP and Dex groups.In group Dex,dexmedetomidine 50μg/kg was injected intraperitoneally once a day starting from the end of operation until the animals were sacrificed.The equal volume of normal saline was given instead of dexmedetomidine in S and NP groups.The mechanical paw withdrawal threshold (MWT) and thermal paw withdrawal latency (TWL) were measured at 1 day before ligation (T0,baseline) and 3,7 and 14 days after ligation (T1-3).Eight animals were sacrificed after measurement of pain threshold at T13 and the dorsal root ganglions of the lumbar segments (L44) were removed for detection of c-fos expression (by immuno-histochemistry).Results Compared with group S,MWT was significantly decreased,TWL was shortened,and the expression of c-fos protein was up-regulated at T1-3 in NP and Dex groups.Compared with NP group,MWT was significantly increased,TWL was prolonged,and the expression of c-fos protein was down-regulated at T1-3 in Dex group.Conclusion Dexmedetomidine can inhibit upregulation of c-fos protein expression,thus attenuating NP in rats.

Objective To explore the motion features of cervical spine based on continuous X-ray images.Methods The cervical spontaneous continuous multi-frame sagittal images from flexion to extention positions were selected from cervical spondylosis patients (patients group) and healthy adult (normal group).After preprocessing and registration,the trajectory of single vertebral body were recorded,and the feature points of each vertebral body were extracted.Meanwhile,the rel ative geometry parameters and movement rate were calculated.Results The motion trajectory of patients' cervical spine C4-6 were different from healthy people.The angles between the left edge curve of the vertebral body (C4 and C5 vertebra) and the baseline of patients group were smaller than those of normal group in flexion position (all P＜0.05).There were instability in the movement of C4 vertebral body in patient group,and the volatility of the angle change,the rate of change and the frequency were larger.The relative position change of the adjacent single vertebral body in the patient group are smaller.Conclusion Through the preprocessing,registration,parameter extraction and result analysis,the changes of functional features in cervical spondylosis patients are truly reflected.And it also provides a new idea for dynamic analysis of cervical vertebrae based on X-ray images.

Objective To explore the mechanisms of synergic action of commonly-used herb pair of Radix Sophorae Flavescentis (Kushen, KS) and Fructus Cnidii (Shechuangzi, SCZ) for the treatment of pruritus. Methods We predicted and analyzed the potential targets of KS and SCZ based on network pharmacology method, and then established Chinese herbs-compound skeletons-targets networks to reveal anti-pruritus targets, predicting targets, and the interaction of KS and SCZ, as well as the components of the herb pair. The RAW264.7 inflammatory cell model was established to observe the synergistic anti-inflammatory activity of KS and SCZ. Results KS and SCZ had possible synergic action on the pruritus-related targets such as histamine receptors, cannabinoid receptors and proteinase-activated receptor 2. Additionally, KS and SCZ probably had synergic regulation of inflammation-related pathway (Toll -like receptor signaling pathway , chemokine signaling and Fc epsilon RI signaling pathway) and nerve-related pathway(neurotrophin signaling pathway) during the treatment of pruritus. Flavones from KS and coumarin of SCZ had various synergistic anti-inflammatory activities(P<0.05), indicating that they played an important role in inhibiting pruritus induced by inflammation. Conclusion The method may reveal the molecular mechanism of KS and SCZ in inhibiting pruritus, which is important for the modernization of Chinese medicine and new drug development.

Objective To investigate the protective effects of Erqi Decoction(EQD; mainly composed of Radix Aristolochiae Kaempferi, Radix Rhizoma Seu Flos Cypripedii, Cortex Fraxini, Cortex Phellodendri, Radix et Rhizoma Rhei) on the intestinal tract in rats with acute radiation intestinal injury and its mechanism. Methods Sixty SD rats were randomly divided into normal group, model group, EQD group and Baitouweng Decoction group (BD group), 15 rats in each group. The acute radiation enteritis model was established by exposing the whole abdomen to a total dose of 10 Gy of 6 MV higher-energy X-rays. EQD group and BD group were given intragastrical administration with corresponding medicine of EQD at the dose of 8.85 g·kg-1·d-1, BD at the dose of 4.69 g·kg-1·d-1 respectively, and the normal group and the model group were given intragastrical administration with the same volume of normal saline. The treatment lasted for 7 continuous days. After modeling, the morphological change of the proximal ileum tissue was observed under light microscope. Villus height, crypt depth, and thickness of the ileal mucosa and entire wall were measured by image analysis system. The myeloperoxidase (MPO) content in ileum tissue was determined by spectrophotometer, and the expression levels of caspase -3 and proliferating cell nuclear antigen (PCNA) in ileum tissue were determined by immunohistochemistry. Results EQD group and BD group had milder injuries of the ileal structure, and had higher villus height, crypt depth, and thickness of mucosa and entire wall than those in the model group (P <0.05), but there were no differences between the two medication groups(P > 0.05). MPO content in EQD group and BD group was decreased(P<0.05 compared with that in the model group), and MPO content in EQD group was lower than that in BD group. The expression levels of caspase-3 and PCNA were increased in EQD group and BD group(P < 0.05 compared with those in the model group), but there were no statistical differences between the two medication groups (P>0.05). Conclusion EQD has certain protective effects against radiation-induced intestinal damage, which mechanism is probably associated with relieving the local intestinal inflammatory reaction, accelerating intestinal epithelial cell proliferation, and inhibiting intestinal epithelial cell apoptosis.
