[Objective]To investigate the expression of protein destrin in cytoskeleton protein in traumatic arterial aneurysm(TAA) vessel wall tissue and its relationship with clinical representations and pathological characteristics.[Method]Western-blot analysis and RT-PCR were used to detect the quantitative expression of destrin protein in 13 patients with TAA and in the femoral arterial tissues of 8 normal subjects.The difference of protein expression was compared,and the results with clinical data were analyzed statistically.The correlation of unbalanced expression of destrin protein with the clinical presentations was studied.[Result] The expression of destrin in TAA tissue was lower than that in the femoral artery of normal subjects(P

The value of dobutamine 99m橳c-MIBI SPECT (DBA-SPECT) for detecting coronary artery disease was assessed in 56 patients with chest pain. Exercise ECG, DBA-ECG and DBA-SPECT were obtained. The hemodynamic changes in DBA infusion are similar to that in exercise test. In 21 patients who had coronary angiogram,the sensitivity,specificity and accuracy were 87. 5% ,76. 9% ,81. 7% ,respectively in DBA-SPECT;75. 0%, 92. 3%, 85. 0%, respectively in DBA-ECG,and 87. 5%,46. 2% ,61.9% ,respectively in exercise ECG test. The results showed that DBA-SPECT is a feasible safe and non-invasive method for detecting coronary artery disease.

Chuan Ya Wai Bian (External Therapies of Folk Medicine), compiled by ZHAO Xue-min, a medical expert in Qing Dynasty, is abundant in folk external therapies including acupuncture, moxibustion, acupoint sticking therapies, which all have unique features. Folk acupuncture-moxibustion is an important part of acupuncture- moxibustion therapy, playing a role that can't be replaced by conventional acupuncture-moxibustion. It's worth exploring and needs constant improvements to adapt to the requirement of modern medicine, which is also significant for boosting the development of acupuncture-moxibustion therapy.

Spasticity is a common complication of stroke.It may cause the function and ability of patients to be restricted significantly and affect the quality of life of both patients and their caregivers.The estimated prevalence of poststroke spasticity (PSS) is 19％ to 42.6％.PSS can be usually assessed by the Modified Ashworth Scale,Modified Tardieu Scale,and electromyography.Therapeutic methods of PSS include physical therapy and drug treatment.The treatment options should be individualized.

Objective This study aims to test the hypothesis that low density granulocytes (LDGs) is involved in the pathogenesis of DM associated-Interstitial lung disease (ILD).Methods Forty eight DM patients (28 with ILD) and 19 age-and sex-matched healthy Chinese volunteers were recruited to this study.LDGs percentage in peripheral blood mononuclear cells (PBMCs) was tested by flow cytometry.Neutrophilrelated genes (LL-37,MPO and MMP-8) expressions in PBMCs were tested by quantitative RT-PCR.Myositis disease activity assessment visual analogue scales (MYOACT) was used to assess the disease activity.Percentages of LDGs were compared in patients with ILD and without by using unpaired t test with Welch's correction,the correlations between LDGs and clinical parameters were further analyzed by linear correlation analysis.The expressions of neutrophil-related mRNA and proteins in PBMCs were compared by using MannWhitney U test.Results LDGs percentage in PBMCs was 7.1-fold higher in DM patients than healthy controls [(9.1±11.5)％ vs (1.3±0.7)％,t=4.664,P＜0.01].LDGs percentage in PBMCs was 2.7-fold higher in DM patients with ILD than DM patients without ILD [(12.3±14.1)％ vs (4.5±2.6)％,t=2.835,P=0.008 3].The mRNA expression level of LL-37,MPO and MMP-8 and LL-37 protein levels in the DM group were significantly higher than those in the control group.LDGs percentage positively correlated with MYOACT lung disease activity scores (r=0.439,P=0.010).Conclusion Percentage of LDGs in PBMCs is significantly increased in DM patients with ILD and positively correlated with MYOACT lung disease activity scores,suggesting that abnormall increasing of LDGs is a potential contributor to the pathogenesis of DM-associated ILD.

Combined hepatocellular and cholangiocarcinoma (HCC-CC) is a rare primary hepatic neoplasm (PHN) with features of both hepatocellular and biliary differentiation. Hepatitis B and hepatitis C are the major causes of HCC-CC. Surgical treatment is the main therapeutic method for HCC-CC. For patients with unresectable lesions, curative or palliative locoregional therapy is applied, including radiofrequency ablation (RFA), transarterial chemoembolization (TACE) and supportive treatment. Because of the rare occurrence and ambiguous clinical features of HCC-CC, it is most often misdiagnosed with the other two types of primary liver cancer. Thus, the realization of the current progress of combined hepatocellular and cholangiocarcinoma is particularly important for us. This article aims to summarize the epidemiology and clinical futures, the treatment and prognosis, the progress of genetics and molecular analysis of HCC-CC.

The expression of microRNA (miRNA) is closely related to radio-chemosensitivity in glioma stem cells (GSCs).Moreover,the growth of glioma stem cells could be inhibited comprehensively by increasing radio-chemosensitivity and apoptosis,simultaneously with the regulation of a single miRNA,which has been confirmed by some researches.Thereby microRNA is prospective for the adoption as a specific agent in targeted therapy of glioma,so as to increase the radio-chemosensitivity in glioma stem cells.

AIM: To study the relationship between the disturbance of nitric oxide/endothelin-1(NO/ET-1) and hepatic ischemia/reperfusion(I/R) injury as well as the regulation of NO/ET-1 system by hepatic ischemic preconditioning(IPC). METHODS: The changes of NO/ET-1 system and their relationship with hepatic I/R injury were compared between I/R group and IPC+I/R group in a rat hepatic I/R model. Two hours after reperfusion, the liver tissues were detected by RT-PCR to see whether there was inducible nitric oxide synthase (iNOS) mRNA expression. RESULTS:In the acute phase of hepatic reperfusion, the ratio of NO/ET-1 was reduced, which was due to a significant reduction of NO - 2/NO - 3 (the metabolic product of NO) and significant elevation of ET-1 in the blood plasma. The content of ALT, AST, LDH and TNF-? in blood plasma, and of MDA in liver tissue were increased but ATP in liver tissue was reduced, the hepatic damage was deteriorated. The protection of the hepatic IPC was concerned with the elevation of the ratio of NO/ET-1 caused by the elevation of NO - 2/NO - 3, and reduction of ET-1 as well. There was no iNOS mRNA detected in the liver tissues.CONCLUSION: Hepatic I/R injury is related to the disturbance of NO/ET-1. The protection of the hepatic IPC in the acute phase might be conducted by its regulation of NO/ET-1 system. The cNOS rather than the iNOS generated the NO in this situation.
