Objective To compare the therapeutic efficacy and safety of ultrasound-guided thrombin injection (UGTI) combined with saline injection and ultrasound-guided compression repair (UGCR) for upper limb pseudoaneurysm (PSA). Methods The clinical features and therapeutic efficacy of UGCR and UGTI for PSA of the upper extremities were retrospectively assessed after catheterization through radial artery. When UGCR was conducted, PSA, its communicating emissaries with other arteries were first identified with color Doppler, and then direct manual compression over the aneurysm for 30 minutes until complete thrombosis was observed. When UGCR failed, a 20-22G needle was inserted into PSA and saline was injected with continuous color Doppler guidance to confirm that the tip of the needle was in the aneurysm. Then thrombin was injected into the aneurysmal sac. All the patients were followed-up clinically and with ultrasound 24h or 14-30 days after the treatments. Results For the 14 patients with upper limb PSA who received UGCR for the first time, 5 were cured with a success rate of 35.7%. Nine cases underwent repeated UGCR treatment, and it was successful in four patients. The overall success rate for UGCR was 64.3% (9/14). All the five patients in whom UGCR failed were successfully cured when UGTI was conducted. In four cases it was successful after the first UGTI, and only one patient received repeated UGTI treatment. The total success rate for UGTI was 100% (5/5). No obvious adverse effect and recurrence were found after follow-up for 14-30 days in all patients. Conclusions Both UGCR and UGTI are safe, effective, and expedient treatment for patients with PSA in the upper extremity. UGTI is the preferred method for its simplicity, high success rate and avoidance of possible distal arterial embolism.

Objective To investigate the effect of human hepatocellular carcinoma HepG2 cell-derived Exosome on the differentiation of mesenchymal stem cells(MSC)into cancer-associated myofibroblasts(CAF)and the impacts of CAF on liver cancer cell proliferation,migration,and invasion. Methods The protein expression of HepG2 cell-derived Exosome was detected by Western blotting. MSCs were separated from human adipose tissue and cultured with HepG2 cell-derived Exosome(100 ng/nl)to initiate differentiation. The expressions of mesenchymal markers and several interleukins were also detected by Western blotting. HepG2 cells were co-cultured with the conditioned media(CM),in which HepG2 Exosome induced the differentiation of MSC into CAF. The expressions of epithelial and mesenchymal markers were detected by real-time polymerase chain reaction(PCR)and Western blotting. Cell proliferation was assessed using MTS assay. Transwell chambers were used in the in vitro migration and invasion assay. Results HepG2 cell-derived particles expressed CD63,70 kilodalton heat shock proteins,and 90 kilodalton heat shock proteins. With the treatment of HepG2 cell-derived Exosome,the expressions of mesenchymal marker α-smooth muscle actin,fibroblast activation protein α,interleukin(IL)-6,IL-8,and IL-1β were up-regulated,while vascular endothelial growth factor had no significant change. The conditioned media which HepG2 Exosome induced MSC differentiation CAF(CAF-CM)could significantly promote HepG2 cells proliferation(1.075±0.104),compared to BSA control(0.874±0.066,P=0.023)and MSC-CM(0.649±0.034,P=0.0005). CAF-CM could significantly enhance cell migration [(42.5±9.1) cells vs.(18.5±3.1) cells,P=0.001] and invasion [(29.0±3.5) cells vs.(13.1±3.7) cells,P=0.009] compared to its control group. Moreover the conditioned medium which HepG2 Exosome induced MSC to differentiate into CAF could also promote the expressions of mesenchyme-related genes Smad interacting protein 1(P=0.040),β-catenin(P=0.038),fibronectin(P=0.029),and Vimentin(P=0.013)and inhibit the expression of epithelial related genes zonula ocdudens-1(P=0.010).Conclusions Exosome extracted from HepG2 cells can induce human adipose-derived MSC to differentiate into cancer-associated myofibroblasts. CAF-like cells can promote the migration of the liver cancer cell line HepG2.

AIM: To investigate the effect of recombinant human interleukin-10 (rhIL-10) on IL-6 and TNF-? levels in serum and liver of mice exposed to lipopolysaccharide (LPS). METHODS: rhIL-10 was prepared by using genetic engineering technology. Mice were intraperitoneally with 500 ?g of LPS, and then were treated intravenously with various dosages of rhIL-10. The levels of IL-6 and TNF-? in hepatic tissue and serum were determined by ELISA at 12 h, 24 h, 48 h and 72 h post rhIL-10 treatment. RESULTS: rhIL-10 markedly inhibited the increase in IL-6 and TNF-? levels in hepatic tissue and serum at 12 h after rhIL-10 treatment in LPS-challenged mice, and the inhibition effect was significant at 24-48 h after rhIL-10 treatment (P

AIM:To investigate the expression pattern of apolipoprotein M (apoM) protein in renal cortex of acute renal failure (ARF) rats with reperfusion. METHODS:Seventy-five male rats were randomly divided into sham operation group (n=25),ARF group (n=25) and pyrrolidine dithiocarbamat (PDTC) group (n=25),five subgroups at time points of 3 h,6 h,12 h,24 h and 48 h after reperfusion were set up in each group. The expressions of apoM in cytoplasm and NF-?B p65 in nucleus of renal cortex were detected at the indicated time points. RESULTS:The expression of apoM in ARF group was obviously higher than that in sham operation group (P

Objective To investigate the role of regulatory B cells (Breg)in children with newly diagnosed immune thrombocytopenia (ITP).Methods A total of 35 newly diagnosed ITP children admitted to the Pediatric De-partment,the First Affiliated Hospital of Zhengzhou University from January to December 201 4 were recruited in this study,and another 20 gender -and age -matched healthy children from the Department of Medical Examination Center of the same Hospital were recruited as controls during the same period.Peripheral blood samples (3 mL from each chil-dren)were collected from all the newly diagnosed ITP children and the normal controls.Breg cells were tested by Flow Cytometry,and the expression levels of interleukin -1 0 (IL -1 0)and transforming growth factor -β1 (TGF -β1 ) mRNA were measured by real time fluorescence quantitative polymerase chain reaction.Meanwhile,the correlation be-tween Breg cells and the expression levels of IL -1 0,TGF -β1 mRNA were analyzed by Pearson correlation.Results The percentages of Breg cells in the peripheral blood of the newly diagnosed ITP children [(2.37 ±0.67)%]were sig-nificantly lower than those of the normal controls [(4.92 ±1 .32)%],and there was a significant difference (t =-7.47,P =0.000);the expression levels of IL -1 0 mRNA in the newly diagnosed ITP children(0.202 ±0.059) were significantly decreased compared with those of the normal controls(0.41 5 ±0.21 2),and there was a significant difference(t =-5.1 75,P =0.000);while the expression levels of TGF -β1 mRNA in the newly diagnosed ITP chil-dren(1 .587 ±0.823)were significantly increased than those in the normal controls(0.61 9 ±0.322),and there was a significant difference(t =4.081 ,P =0.001 ).There was a significant positive correlation between Breg cells and the ex-pression levels of IL -1 0 mRNA(rs =0.828,P <0.05),but no correlation between Breg cells and expression level of TGF -β1 mRNA was found (rs =0.527,P =0.1 1 7).Conclusions The decrease expressions of Breg cells can be found in the newly diagnosed ITP children,and the abnormal expression of Breg cells may play a key role in the immu-nological pathogenesis of the newly diagnosed ITP children.

To study the current situation of Chinese medicine services from both perspective of supply and demand, looking to promote the healthy development of Chinese medicine community health service strategy. Questionnaire survey was conducted to practitioners of 14 community health service centers in Longhua district (80) and service objects (800). Ratios and SWOT methods were used for analysis. 75 qualified practitioners and 736 qualified service objects questionnaire recoveries showed that there are different degrees of commands from both sides, different options on therapeutic methods and lack of practitioners. It is suggested that community health service center should supply TCM service according to different time, different place and different patient on different type and levels.
