2.The clinical value of Tei index in the evaluation of left ventricular function of diabetic patients with normal LVEF
Chinese Journal of Primary Medicine and Pharmacy 2013;20(22):3388-3390
Objective To observe the value of myocardial performance index (Tei index) in evaluating the left ventricular function in diabetic patients with normal left ventricular ejection fraction (LVEF),and to investigate its correlation with plasma N-terminal pro-brain natriuretic peptide (NT-proBNP).Methods 96 diabetic patients with normal LVEF were selected as the observation group,50 healthy persons were selected as control group.Left ventricular Tei index was measured by color Doppler ultrasound.The plasma NT-proBNP was detected.Results The Tei index,plasma level of NT-proBNP of the observation group were (0.49 ± 0.11),(397.6 ± 39.4) ng/L,those of the control group were (0.32 ± 0.07),(101.2 ± 18.4) ng/L,the differences between the two groups were statistically significant(t =11.357,1.992,all P < 0.05).There was significant positive correlation between Tei index and plasma NT-proBNP in the observation group(r =0.661,P < 0.05).Conclusion Combined determination of Tei index and plasma NT-proBNP can detect early myocardial damage in patients with diabetes mellitus.

Journal of Chinese Physician 2017;19(3):341-344,348
Neurogenic bladder is a class of diseases in the damage of normal urine and storage function that are resulted from any cause of central or peripheral nerve damage,which is also called neurogenic bladder dysfunction (neuropathic bladder dysfunction,NBSD).Children~ neurogenic bladder is a common cause of congenital spinal cord dysplasia with high morbidity,and progressive development can cause the urine impaired even life-threatening.The treatment of neurogenic bladder cannot obtain satisfactory results yet.This review summarizes the recent advances in the treatment of neurogenic bladder.

Objective To explore the expression of nitric oxide synthases including neuronal nitric oxide synthases(nNOS), inducible nitric oxide synthases(iNOS), endothelial nitric oxide synthases (eNOS) in neurogenic bladder tissues, and analyze it's producing feature and significance. Methods There were 30 cases with neurogenic bladder(18 males, 12 females). The average age was 6.3±3.1 years. All patients appeared with myelodysplasia, urinary and fecal incontinence in different degree. Twenty-six cases were manifested with hyperreflexia bladders, and all patients were treated with surgical procedures. During operation, collected bladder tissue samples including tissues of apex vesicae and tissues of bladder neck, and all tissues were enveloped with mineral wax. All tissues were detected for nNOS, iNOS, and eNOS respectively in tissues of apex vesicae and tissues of bladder neck,and with normal bladder tissues as control group (bladder tissues of hypospadia, 10 cases), and according to clinical features, to explore the expression of NOS, and to analyze the relationship among them. Results In normal apex vesicae tissues, all cases stained with nNOS, and distributed among bundles of smooth muscles, and surface of smooth muscles and interstitial tissue, histochemica;score (HS) 2.8-4.0 and 1.2-2.7. There were no stained cells in bladder tissues of iNOS, and HS was very low, HS:0-0. 4 and 0-0.1 ;eNOS mainly distributed in interstitial tissues in rarefaction manners, and mainly in vascular endothelial cell (VEC), and smooth muscles had no stainings the most expression among them was nNOS, and mainly distributed in bladder neck tissues. In neurogenic bladder tissues, the main expression of NOS type was iNOS, and nNOS decreased significantly. eNOS mainly expressed in VEC among interstitial tissues, and had no staining in smooth muscle cells and collagenoblast and rarefaction of microvessel in bladder tissues, and microvessel density decreased significantly than normal bladder tissues. Microvessal density(MVD) in bladder tisssus (6. 8± 3.2/100per square) was less than that in normal tissues (16.7±6.3/100 per square). Conclusions In normal bladder tissues, nNOS mainly distributes in bladder neck and urethra, and nitric oxide mainly derives from nNOS. Much more matrix fibers, fewer nitrogenergic nerves, and less nNOS expression are seen in neurogenic bladder interstitial tissue. There are more iNOS expressions in bladder tissues,and NO is mainly derived from iNOS, and it may play an important role in pathological bladder tissues, especially in fibrosis of bladder wall. eNOS may be considered as angiopoietic labeling, and may evaluate the blood supply of bladder.

Objective To infect human pulmonary artery smooth muscle cells with different HIV-based vectors, and introduce foreign genes into the cells with HIV-based lentivirus vectors.MethodsThe human pulmonary artery smooth muscle cells, U87.CD4.CCR5 and U87.CD4.CXCR4, were infected with ADA/Luc, HXB2/Luc, VSV-G/Luc and VSV-G/GFP.ResultsU87.CD4 with corresponding coreceptors could be infected by ADA/Luc and HXB2/Luc, however, the human pulmonary artery smooth muscle cells could not be infected by ADA/Luc and HXB2/Luc, even pseudotypes. VSV-G/Luc and VSV-G/GFP could be transfered into the human pulmonary artery smooth muscle cells. After 3 days post-infection, the relative proportion of positive cells of human pulmonary artery smooth muscle cells expressing VSV-G/GFP was 18%.ConclusionHIV-based lentivirus vectors can introduce foreign genes into the human pulmonary artery smooth muscle cells.

Objective To analyze the level of Th17 and Treg cells in the peripheral blood of patients with rheumatoid arthritis(RA),and to investigate its role in the pathogenesis of RA and the clinical significance.Methods Flow cytometry(FCM)was used to analyze the ratio of interleukin(IL)-17+CD4+T (Thl7)cells and Foxp3+CD25+CD4+T(Treg)cells in CD4+T cells from the peripheral blood of 57 RA patients and 32 normal controls.T-test and Chi-square test were used for inter-group comparison and Pearson's linear analysis was used for correlation analysis.Resuits Compared with normal controls.the level of both IL-17+CD4+T cells and the ratio of Th17/Treg in RA patients increased significantly.while the level of Foxp3+CD4+CD25+T cells decreased markedly[(4.2±2.2)%vs(2.3±1.4)%,P=0.000;1.15±0.62 I)5 0.34±0.17,P=0.000;(3.9±1.6)%vs(7.0±2.2)%,P=0.000].Compared with early RA(persistent for 2 years or less)patients,the levels of Th17,Treg and the ratio of Th17/Treg in chronic RA(duration for more than 2 years)patients didn't markedly changed(P>0.05).The level of Th17 cells and the ratio of Th17/Treg was directlycorrelated with disease activity parameter (including tender ioint counts,visual analog seale of patients,disease activitv score in 28 joints,etc).Regression analysis discovered that risk factors of bone erosion were the level of Th17 cells,the ratio of Th17/Treg,disease activity score in 28 joints and disease duration.Antirheumatic drugs could decreascthe ratio of Th 17/Treg.Conclusions Treg cells is decreased in RA patients while Th7 cells is increased in patients with RA.Th17/Treg ratio goes up significantly as well.Change of T celt subsets,especially Th17 and Treg cells are important for the pathogenesis of RA.Th17 and Treg cells could aggrevate disease activity and bone destruction throughout the whole disease process.Anti-rheumatic medications is effective by regulating Th17/Treg subset balance.
