Objective: To investigate the clinical therapeutic effects on ischemic stroke by syndrome(differentiation) in traditional Chinese medicine(TCM) combined with differential diagnosis in western medicine.Methods: One hundred and thirtyeight cases suffered from ischemic stroke were randomly divided into treatment group and control group,and according to TCM(theory) the(treatment) group was subdivided into Qideficiency(气虚),phlegm(dampness)(痰湿),phlegmfire(痰火) and Yindeficiency(阴虚)(subgroups).(Different) TCM decoction was administrated respectively to the four subgroups.The clinical(symptoms) and signs,tongue picture of TCM diagnosis as well as the changes of national institutes of health stoke score(NIHSS) were observed and compared with those of the control group before and after treatment.Results: NIHSS scores were improved in all the groups(P

Objective To analyze the clinical efficacy of daily online cone-beam computed tomography (CBCT)-guided stereotactic body radiation therapy (SBRT) for primary and metastatic lung cancer and its related factors.Methods From May 2009 to May 2013,36 patients with lung cancer were treated with SBRT,including 24 patients with primary lung cancer and 12 patients with metastatic lung cancer.The biologically effective dose at 10 Gy was ≥ 100 Gy in 85.7％ of 42 lesions.Before each delivery,CBCT was acquired,and online automatic or manual registration was performed to make the tumors on CBCT within the planning target volume/primary gross tumor volume;the setup threshold was not set,and the couch was moved for correction.Results The 1-,2-,and 3-year sample sizes were 36,29,and 26,respectively.The 1-,2-,and 3-year local control (LC) rates were 96％,89％,and 72％,respectively.The 1-,2-,and 3-year cancer-specific survival (CCS) rates were 82％,74％,and 64％,respectively.The 1-,2-,and 3-year overall survival (OS) rates were 78％,64％,and 53％,respectively.Univariate analysis found no factors associated with LC.Multivariate analysis revealed no factors associated with OS.Both univariate and multivariate analyses showed that only tumor location (central type or peripheral type) was associated with CCS;the mean values (95％ confidence intervals) of CCS in patients with central-type and peripheral-type lesions were 21.4 months (13.2-29.6 months) and 42.3 months (35.7-49.0months),respectively (P=0.024).Conclusions Daily online image-guided SBRT for primary or metastatic lung cancer can lead to a satisfactory LC.

Objective To investigate the effect of 12-lipoxygenase (12-LO) on the angiotensinⅡtype 1 receptor(ATlR) expression in mesangial cells (MC).Methods p38 MAPK activation and ECM protein expression were determined using AngⅡ-stimulated MC derived from normal and 12-LO knockout mice.AT1R expression was determined using 12-LO product 12(S)- HETE-stimulated MC,MC transfected with 12-LO gene and microdissected glomeruli derived from 12-LO knockout mice.RT-PCR and Western blot were used for evaluating mRNA and protein expression respectively.Results AngⅡstimulation increased p38 MAPK activation and ECM protein expression in normal MC,but not in MC derived from 12-LO knockout mice.Time-dependent and dose-dependent experiment showed that 12 (S)- HETE increased AT1R protein' expression in MC. Similarly,12 (S)-HETE increased AT1R mRNA expression in MC compared with control MC (P＜0.01). Furthermore,AT1R expression was lower in glomeruli derived from 12-LO knockout mice relative to genetic controls (P＜0.01) and MC stably overexpressing 12-LO had greater AT1R protein and mRNA expression relative to control MC (P＜0.01).Conclusion 12-LO activation can upregulate ATIR expression in MC.

Objective To investigate the effect of focal cerebral ischemic preconditioning (IPC) on brain edema and the expression of nuclear factor-?B( NF-?B) and its target gene MMP-9. Methods Forty-five SD rats were divided into 3 groups in which control group received sham surgery only, and the other two groups received 2 hours of middle cerebral artery occlusion (MCAO) followed by 22 hours of reperfusion with or without 10 minutes of IPC 3 days before. Brain water content, expression of NF-?B and MMP-9 mRNA were evaluated in each group by wet-dry weight method, immunohistochemistry staining and RT-PCR. Results Compared with the SS group, there was a lower NF-?B immunoreactivity and MMP-9 mRNA level (16 098.2?1 265.3 vs 23 565.8?1 978.4,50.7% vs 84.1%, P
