Objective To study the correlation between serum homocysteine (Hcy) levels and chronic heart failure (CHF) with ultrasound cardiac function patients.Methods The subjects were 88 cases of CHF (CHF group) in our hospital between April 2014 to June 2015 between patients,selected 65 cases of healthy people as a control group over the same period in our hospital,using color Doppler ultrasound measurement of two groups patients of the left ventricular ejection fraction of patients groups (LVEF) and left ventricular end-diastolic diameter (LVEDd),and compared serum Hcy and NT-proBNP levels,LVEF and LVEDd in different NYHA classification patients,analysis of serum Hcy and NT-proBNP levels and LVEF,LVEDd between correlation of serum Hcy levels on cardiovascular incident.Results CHF group of the Hcy,NT-proBNP levels and LVEDd were significantly higher than control group (P < 0.01),LVEF was significantly lower than the control group (t =31.78,P =0.00);different NYHA functional class (Ⅱ ~ Ⅳ level) of Hcy,NT-proBNP,LVEDd and LVEF compared were statistically difference (P < 0.01);Pearson correlation analysis showed,CHF patients with LVEF serum Hcy levels were negatively correlated (r2 =0.974,P < 0.01),with LVEDd was positively correlated (r2 =0.896,P < 0.05),and higher serum Hcy levels,the higher the rate of cardiovascular happened in patients with CHF.Conclusion The serum Hcy and NT-proBNP levels in patients with CHF were significantly higher than healthy,and with the deterioration of heart function and increased while the LVEF was negatively correlated positively with LVEDd,cardiovascular events in high Hcy levels may also increase the incidence risk,so Hcy levels is expected as a new diagnostic marker CHF conditions change.

Objective To investigate the expression of peroxisome proliferator-activated receptors (PPARs) in epidermal keratinocytes of patients with psoriasis vulgaris and its significance.Methods Immunohistochemical method was used to examine the expression of PPARα,β/δand.γ in tissue specimens from the normal skin of 5 human controls,lesional and normal skin adjacent to the lesions of 17 patients with psoriasis vulgaris.A semi-quantitative analysis was carried out by image analyzer.Results Different levels of expression of the three PPAR isotypes were observed in the nuclei of epidermal keratinocytes of normal human controls.The expression intensity of PPAR α,β/δand γ was statistically higher in the epidermis of adjacent normal skin than that in psoriatic lesions(all P<0.01)and normal control skin(all P<0.01).Conclusions The decreased expression of PPARα may be associated with the overproliferation and parakeratosis of epidermal keratinocytes in psoriatic lesions,and PPAR β/δ and γ may display a synergistic effect on the maintenance of homeostatic proliferation and difierentiafion of epidermal cells.

Objective To improve the diagnosis of tuberculosis ( TB) by analyzing Mycobacterium infection in fine-needle aspiration biopsy specimens from children with tuberculous lymphadenitis .Methods Fine-needle aspiration biopsy was performed on 269 children with tuberculous lymphadenitis diagnosed by Shanghai Public Health Clinical Center from January 2011 to September 2013 .The needle aspiration biopsy specimens were processed for acid-fast bacillus (AFB) smear test, mycobacterial culture and Mycobacterium identification ( p-nitrobenzoic acid inhibition test ) .Results Cytological diagnosis of tuberculous lymphade-nitis was made for 269 patients.The positive results by AFB smear test were detected in 63.19% of 269 specimens (n=170) and 40.15%(n=108) specimens were positive in mycobacterial culture .The differ-ence between the two tests were significant (P<0.01).The positive rate of Mycobacterium detected by using BACTEC MGIT 960 automated system and L?wenstein-Jensen culture method were 38 .66% ( n=104 ) and 28.99%(n=78), respectively, showing the significant difference between two tests (P<0.05).AFB smear test in combination with mycobacterial culture could precisely diagnose 70.63% of tuberculous lym-phadenitis in children.Of the 108 clinical isolates, 105 strains (97.2%) were Mycobacterium tuberculosis complex and the rest were non-tuberculous Mycobacterium strains (2.8%).Conclusion The positive rate by AFB smear test was significantly increased in fine needle aspiration biopsy specimens after a series of treatments including sample digestion , centrifugation and precipitation , but the positive rate of mycobacterial culture was reduced .Diagnostic accuracy could be significantly improved by using BACTEC MGIT 960 sys-tem.Mycobacterium tuberculosis complex was the predominant pathogenic bacterium in children with tubercu-lous lymphadenitis .

It is reported by current investigations,that BNP can suppress heart hypertrophy but it can also depress compensatory hypertrophic response.BNP is an useful marker in the early diagnosis,prognosis,therapy guiding of heart failure and coronary heart disease,but comorbid conditions should be considered in the diagnosis of heart failure.The polymorphism in the 5'-flanking region of the NPPB gene is found to be related with essential hypertension.On the basis of some investigation,it is supposed that the instillation of BNP at the early stage of hypertension will contribute to therapy of hypertension.

Objective To investigate motor activity of gastrointestinal tract in patients with slow transit constipation(STC). Methods 42 patients with STC and 20 healthy controls were included in the study. Each subject underwent colonic transit test, gastric emptying, orocecal transit time, electromyography and anorectal manometry. Results According to transit index, 42 STC patients were divided into 3 types: ①0.5

[Summary] The relationship between the state of cognition and hypertension in 155 type 2 diabetic patients was studied.The results showed that significant difference in the state of cognition was found in patients with or without hypertension,so as to those with poorly or well controlled hypertension (P<0.05).Systolic blood pressure,pulse pressure,mean arterial blood pressure,and duration of hypertension were negatively correlated with multiple cognitive domains,suggesting that proper control of blood pressure may have a protective effect on cognitive function in type 2 diabetic patients.

To establish a method for radioligand binding assay of thyroid hormone receptors(TR)in human osteoblast-like osteosarcoma cell line MG-63 and to estimate the kinetic parameters of putative receptors. The MG-63cell was cultured in Ham's F12, the soluble TR was prepared from the intact nuclear extracts. The binding properties between TR and T3 were performed by using the traditional Scatchard analysis. The apparent Ka of TR in MG-63 is 7.68× 109 L/mol, and MBC(111. 25+ 10.77)fmol/mg protein. The study indicated that MG-63 cells possessed high affinity and limited-capacity of TR in its nuclear extracts. This may serve as the starting and basic work about TR in bone cell.
