OBJECTIVE:To observe the efficacy and safety of azithromycin sequential therapy combined with terbutaline in the treatment of mycoplasma pneumonia. METHODS:130 children with mycoplasma pneumonia were randomly divided into control group and observation group. Control group was given azithromycin sequential therapy by using 10 mg/kg Azithromycin dispersible tablet by intravenous infusion,once a day,for continuous 3-5 d,then rested for 4 d,and then given 10 mg/kg Azithromycin dis-persible tablet at a draught,once a day,for continuous 3 d,then rested for 4 d;observation group was additionally given 2.5 mg Terbutaline injection adding into 5 ml sodium chloride injection by inhalation via oxygen atomization,twice a day,10-15 min ev-ery times,and then the children were fed with warm boiled waterafter atomization. The treatment course for both groups was 4 weeks. Clinical efficacy,and changes of cytokines levels [tumor necrosis factor-α(TNF-α),interleukin-6 (IL-6),IL-8],disap-peared time of related symptoms and signs (wheezing,rales,coughing,fever),hospitalization time before and after treatment, and incidence of adverse reactions in 2 groups were observed. RESULTS:After treatment,the effective rate in observation group was significantly higher than control group,levels of TNF-α,IL-6 and IL-8 were significantly lower than control group,disap-peared time of related symptoms and signs and hospitalization time were significantly shorter than control group,the differences were statistically significant(P<0.05). There was no significant difference in the incidence of adverse reactions between 2 groups (P>0.05). CONCLUSIONS:Azithromycin sequential therapy combined with terbutalineaerosol therapycan effectively improve the cytokines levels and clinical efficacy,with good safety.

To quantitatively evaluate the upper-limb spasticity of stroke patients in recovery stage, the relationship between surface electromyography (sEMG) characteristic indexes from biceps brachii and triceps brachii and the spasticity were explored, which provides the electrophysiological basis for clinical rehabilitation. Ten patients with spasticity after stroke were selected to be estimated by modified Ashworth (MAS) assessment and a passive elbow sinusoidal motion experiment was carried out. At the same time, the sEMG of biceps and triceps were recorded. The results shows that the reflex electromyographic threshold could reflect the physiological mechanism of spasticity and had significant correlation with MAS scale which showed that sEMG could be prosperous for the clinical quantitative evaluation of spasticity of stroke patients.

Objective To investigate the cerebral regularity of dynamic charge and the correlation with intracranial pressure(ICP),clinical seriousness and prognosis on acute stage of intracerebral hemorrhage(ICH) patients by transcranial Doppler(TCD).Methods 54 patients with first acute supratentorial ICH 24h after onset were studied.All patients were dynamic evaluated by beside TCD on 1st,7th,21st day.The correlation of TCD with ICP,MESSS were studied.Results On the 1st day the TCD abnormity of the acute phase of the ICH occurred mainly in the anterior circulation of cerebrum,in which the cardinal manifestation was high-resistance,low-flow velocity blood waveforms,especially on the bleeding side.Continuous TCD monitoring revealed the low velocity of the cerebral blood flow increased;meanwhile the high value of PI decreased gradually and the TCD monitoring was within the normal range three weeks after the attack.The ICP had negative correlation with the VmMCA,positive correlation with the PI value.MESSS scale had negative correlation with the VmMCA,positive correlation with the PI value.Conclusions The TCD examination can be used to monitor the cerebral hemodynamics of the patients suffering from intracerebral hemorrhage.The combination of fVEP and TCD facilitate the evaluation of the dynamic changes of ICP so as to instruct lowering the ICP.

Objective:To explore the effects of Bailing capsules combined with salvianolate on inflammatory cytokines, renal vas-cular endothelia and renal function in diabetic nephropathy inⅣphase. Methods:Totally 60 patients with diabetic nephropathy in IV phase were randomly divided into the control group (30 cases) and the treatment group (30 cases). The control group was given the conventional and salvianolate therapy, and the treatment group was treated with Bailing capsules additionally. The treatment course was 3 months. The changes of serum creatine(SCr), urean itrogen (BUN), creatinine clearance rate (Ccr), ethelin (ET-1), interleukin-6 (IL-6), tumor necrosis factor (TNF-a) and C-reactive protein (CRP) were detected before and after the treatment. Results:After the 3-month treatment, SCr, BUN, IL-6, TNF-a, CRP and ET-1 were significantly decreased in the two groups with statistical signifi-cance, and Ccr was significantly increased in the treatment group (P<0. 05), and the changes in the treatment group were significant-ly better than those in the control group (P<0. 05). After the treatment, the blood glucose, blood lipids, glycosylated hemoglobin and the other indicators had no significant changes in the two groups (P>0. 05). There was no significant difference in the incidence of adverse drug reactions between the two groups (P>0. 05). Conclusion:The combination of Bailing capsules and salvianolate can re-duce the inflammatory reaction and improve renal vascular endothelial function and renal function in the patients with diabetic nephrop-athy in Ⅳ phase with promising safety and few adverse reactions.

Aim To investigate the in vitro vasorelax-ant effect of DL0805-0, a Rho kinase inhibitor, on iso-lated rat thoracic aorta and explore its underlying mechanism. Methods Tension was measured to eval-uate the vasorelaxant effect of DL0805-0 on rat endo-thelium-intact and endothelium-denuded thoracic aorta rings. Rho kinase inhibitor fasudil, nitric oxide syn-thase inhibitor Nω-nitro-L-arginine methyl ester ( L-NAME), guanylate cyclase inhibitor methylene blue, cyclooxygenase inhibitor indomethacin, calcium-activa-ted potassium channel blocker tetraethyl ammonium ( TEA ) , ATP-sensitive potassium channel blocker glibenclamide and voltage-dependent potassium chan-nel blocker 4-aminopyridine ( 4-AP ) were used to il-lustrate the mechanisms of vasorelaxant effect of DL0805-0 . Results DL0805-0 exerted vasorelaxation in a dose-dependent manner in KCl (60 mmol·L-1 ) or NE ( 0. 1 μmol · L-1 ) -induced contraction. DL0805-0-induced vasorelaxation was significantly re-duced by L-NAME. However, methylene blue and in-domethacin did not significantly affect vasorelaxation of DL0805-0. In endothelium-denuded rings, TEA re-markably attenuated the vasorelaxant effect of DL0805-0 , while glibenclamide and 4-AP did not affect vasore laxation of DL0805-0 significantly. DL0805-0 also re-duced NE-induced transient contraction and inhibited contraction induced by increasing extracellular calci-um. Conclusion These results suggest that DL0805-0 induces vasorelaxation through an endothelium-depend-ent pathway. The opening of calcium-activated K+channels and blocking of Ca2+ channels in vascular smooth muscle cells may be one of the mechanisms of DL0805-0-induced vasorelaxation.

Objective To explore the effect of chemokine CXCL12 and its receptor CXCR4 on proliferation,migration and invasion of epithelial ovarian cancer cells.Methods CXCR4 and CXCL12 mRNA and protein expression of human ovarian cancer cell line CAOV3 was detected by RT-PCR and immunocytochemistry.Integrin ?1 and vascular endothelial growth factor-C(VEGF-C)mRNA expression were detected in CAOV3 cells stimulated by CXCL12.The CAOV3 cells were divided into 6 groups:control group(un-stimulated),experimental group 1(stimulated by 100 ng/ml CXCL12),experimental group 2 (stimulated by 10 ng/ml CXCL12),experimental group 3(100 ng/ml CXCL12 and 10 ?g/ml neutralizing CXCR4 antibody),experimental group 4(100 ng/ml CXCL12 and 1 ?g/ml CXCR4 antagonist AMD3100),experimental group 5(10 ?g/ml neutralizing CXCR4 antibody or ascites).Methyl thiazolyl tetrazolium(MTT)was used to analyze the effects of different concentrations of CXCL12 on CAOV3 cell proliferation.Transwell invasion chamber and reconstructed basement membrane(Matrigel)were used to evaluate effect of various concentrations of CXCL12 and ascites on CAOV3 cell migration and invasion. Results CAOV3 cells expressed CXCR4 mRNA(0.70?0.10)and protein,but did not express CXCL12 mRNA or protein.Immunostaining of CXCR4 was mainly located in cytoplasm.CXCR4 mRNA was up- regulated after 100 ng/ml CXCL12 stimulation(1.24?0.14;t=-7.1088,P=0.0021).Integrin ?1 mRNA was greatly increased at 3 hours by stimulation of 100 ng/ml CXCL12(before and after stimulation 0.53?0.10,1.53?0.16;P0.05).Experimental group 1 stimulated the migration and invasion of CAOV3 cells in chemotaxis assay compared with control group and experimental group 2(number of cell migration respectively 523.3?25.2,108.0?7.2,211.7 ?24.7,number of cell invasion respectively 39.3?4.0,4.0?1.0,15.7?3.1;P

The NSP2 gene of porcine reproductive and respiratory syndrome virus (PRRSV)S1 strain was partly amplified and cloned into a prokaryotic expression vector pGEX-6P-1 and a fusion protein GST-tNSP2 with molecular weight of 50 kDa was expressed in E.coli. The purified GST-tNSP2 protein showed a strong reaction with the PRRSV-positive sera in Western blot assay. Balb/c mice were immunized with the purified protein, and the splenocytes of the immunized mice were fused with murine myeloma cells SP2/0. After subcloning by 3 times, two hybridoma clones which produced McAbs steadily were screened by ELISA, named 3H3 and 2B5. They all reacted strongly with the PRRSV S1 infected Marc-145 cells in IFA, but not with the PRRSV SY0608 strain. Both of the McAbs belong to IgG1 isotype, and their light chains belong ? type. The expressed GST-tNSP2 protein and McAbs could be used for identification of PRRSV isolates and functional analysis of NSP2.
