Objective To measure the serum levels of IL-32 and chemokine CXCL13 in patients with rheumatoid arthritis and explore their clinical value. Methods The serum levels of IL-32 and chemokine CXCL13 were meas-ured by ELISA methods in 102 patients with RA and 50 healthy controls;analyzed the correlation among the IL-32, chemokine CXCL13 and the clinical data, inflammation maker of RA, such as X-ray stage, the bone destruction, the number of tender joints, the number of swollen joints, DAS28,ESR,CRP,CCP,RF,TNF-α,IL-6, etc. Results The serum levels of IL-32 and chemokine CXCL13 were significantly higher in RA patients than that in healthy controls(P<0.05). Moreover,the serum levels of IL-32 and chemokine CXCL13 those patients who had bone de-struction were higher than those with no or mild bone destructions(P<0.05);there was a positive correlation be-tween IL-32, chemokine CXCL13 and X-ray stage, the bone destruction, DAS28, ESR,CRP,CCP,TNF-α,IL-6. Especially, there was a positive correlation between IL-32 and chemokine CXCL13 (r=0.509,P=0.000). How-ever, there was no relationship with the number of swollen joints, tender joints, and RF. Conclusion The serum levels of IL-32 and chemokine CXCL13 were increased significantly,which was closly related with the disease activ-ity and inflammation maker. The results indicate that the abnormality of IL-32 and chemokine CXCL13 may be use-ful for the evaluation of disease activity and monitoring the progress of the disease.

Objective To explore left ventricular longitudinal axis systolic asynchrony by real-time triplane quanti-tativetissue velocity imaging(RT-3PE QTVI) and two-dimensional speckle tracking imaging(STI) in patients with dilated cardiomyopathy. Methods Thirty normal adults were included as the control group and thirty adults with DCM. The images from enough frame rates RT-3PE QTVI and STI were obtained from series long-axis views. Simp-son method was used to measure LVEF. Q-lab software was used to measure peak systolic tissue velocity(Vs) and peak systolic longitudinal strain (Ls),its time to peak point from each segment(Ts,Tls) and the maximal temporal difference of Ts,Tls(Ts-diff,Tls-diff),and the standard deviation of. Ts,Tls(Ts-SD,Tls-SD),which were served as systolic asynchrony indexes in assessing LV longitudinal axis systolic asynchrony. Results ① Compared the con-trol group and DCM group,there were significant differences in LVEDd,LVESd,LVEDL,LVESL,LVEF,FS (P<0.01). ② In comparison with the control group,the Ls and Vs of each segment were decreased in the DCM group (P<0.01). Compared with the control group,the parameters of Tls and Ts in DCM group had obvious ahead or de-layed(P<0.05). ③ Compared with the control group,the parameters of Ts-SD, Tls-SD, Ts-diff, Tls-diff,were significantly different in DCM group (P<0.01). Ts-SD,Tls-SD,Ts-diff,Tls-diff corrrlated negatively to LVEF(r=-0.67,-0.72,-0.75, -0.77,P<0.01). Conclusion The prevalence of left ventricular longitndinal axis systolic asynchrony exits in patients with DCM. There is a better technique to evaluate LV longitudinal axis systolic asynchrony by RT-3PE QTVI and STI than only one.

Objective Via observing concentration changes of interleukin(IL)-1β, IL-6 and IL-18 in hippocampus of pilocarpine treated rats after intranasal delivery of transforming growth factor-β1(TGF-β1), to explore the possi-ble anti-epileptogenic and neuro-protective role of TGF-β1 in the epiletogenesis progression. Methods Three hours after pilocarpine induced status epilepticus, rats were treated with recombinant human TGF-β1 or the same volume of PBS by intranasal administration. Animals were executed, harvested at 24, 48, 72 h after SE individual-ly. Using the methods of the enzyme-linked immunosorbent assay (ELISA) and immunohistochemisty (IHC), the concentrations and distribution of IL-1β, IL-6, IL-18 were detected in hippocampus. Results TGF-β1 could re-duce the expression of IL-1β and IL-6 in the hippocampus of pilocarpine treated rats effectively (P<0.05 or P<0.01), however, TGF-β1 did not affect the expression of IL-18 significantly( P >0.05). Conclusion By the supplementation of intranasal TGF-β1, classical pro-inflammatory cytokine ( IL-1β, IL-6) are remarkably sup-pressed, TGF-β1 may exert antiepileptogenic and neuropretective effects.

80 NSTE-ACS patients were randomly divided into 2 groups: the control group and the therapy group (40 cases in each group). The therapy group was treated with Tirofiban besides the conventional treatment which received by the control group. The level of HIF-1α and hs-CRP was detected immediately, 12, 24, 48 h,and 7 d after hospitalization. The HIF-1αlevel of both group increased in the first 12 hours and then decreased gradually to the baseline in 7 days. The hs-CRP level of both group increased gradually and reached its peak after 24 h after hospitalization, then decreased. Compared with the control group, the level of HIF-1α and hs-CRP decreased sig-nificantly at 12, 24, 48 h and 7 d after hospitalization in the therapy group.

Objective To investigate the influence of endothelial progenitor cells on the proliferation and differenti-ation of neural stem cells in vitro under the condition of co-culture. Methods We used the mature methods of iso-lation, culture and identification on cells to get the spinal cord NSCs and peripheral blood EPCs from the SD rats, and then put them together in the Transwell chamber in vitro. Set the untreated NSCs as a control group. On the 4th day, we calculated the number and diameter of neurospheres. After that, removing the insert of transwell with EPCs, and inducing the NSCs to differentiate. On the 7th day, we conducted MAP-2 immunofluorescence staining on the cells of induced-differentiation group with fluorescence microscopy, then observed the expression of the anti-gen and calculated the percentage of the differential neurons in the NSCs. All the data were analyzed using statisti-cal method. Results The average number of neurosphere in co-culture group was 10.3±2.2,it was significantly more than that in the control group, and the diameter was under the same situation,the average diameter was up to (49.0±5.3)μm. The percentage of the cells which differentiated into neurons in the co-culture group was signifi-cantly higher than that in the control group, the percentage was(32.1±1.8)%. Conclusion EPCs promote the proliferation of NSCs and induce the differentiation of NSCs into neurons in vitro.

31 patients from Anhui province maternal and child health care with cesarean scar pregnancy ( CSP ) treated with UAE ( before or after uterine curettage) were analyzed retrospectively. 12 subjects with a definite diag-nosis of CSP were offered preventive UAE. 1 case of an emergency rupture of the CSP patient was offered emergen-cy interventional therapy. The other eight patients,who were misdiagnosed as having an intrauterine pregnancy,with the symptoms of active vaginal bleeding were treated with emergency UAE after uterine curettage. The results showed all the 31 patients with CSP were resolved successfully without hysterectomy and had a significant decrease on the data ofβ-HCG. 24 patients received preventive UAE combined with methotrexate followed by uterine curet-tage. 3 patients received a excision of the scar in the uterus after UAE. 4 patients had a UAE combined with conser-vative medication. Results showed that UAE might be an effective means of treating CSP, including treatment in an emergency setting. It decreases the incidence rate of hysterectomy.

Objective To investigate the association between TLR4,C-Jun N-terminal kinase,tumor necrosis factor-α(TNF-α),Leptin changes and chronic intermittent hypoxia(CIH). Methods Twenty-four SD rats were divided into 3 groups (n=8):control group,CIH 6 weeks group, CIH 8 weeks group. After the modeling,the change of blood pressure and renal artery were observed by the use of non-invasive blood pressure analyzer and HE staining. ELISA was employed to determine the production of TNF-αand Leptin in sera of these animals. The expressions of TLR4 and JNK mRNA were detected by real time quantitativer everse transcription-polymerase chain reaction ( QRT-PCR) method in the adipose tissue. Results The blood pressure in intermittent hypoxia group was signifi-cantly higher than those in control group(P<0.01), and the renal artery pathological changes in intermittent hy-poxia group were significantly heavier than those in control group;the content of TNF-α and Leptin in intermittent hypoxia was significantly higher than those in control group(P<0.01),and the content of TNF-α and Leptin was significantly increased with the days of hypoxia;the expression of TLR4 and JNK at mRNA levels in intermittent hy-poxia was significantly higher than those in control group(P<0.01),and the expression of TLR4 and JNK at mR-NA levels was significantly increased with the days of hypoxia. Conclusion TLR4,JNK,TNF-α,Leptin may be in-volved in the inflammatory response of chronic intermittent hypoxia in rats.
