Objective To study the correlation between chronic infection of three microorganism and coronary artery lesion by detecting their antibodies and high-sensitivity C-reactive protein(hs-CRP) .Methods According to their severity of coronary artery lesion ,patients enrolled in the study were divided into 4 groups ,including normal control group(n=37) ,single-branch lesion group (n=36) ,double-branch lesion group(n= 30) and multi-branch lesion group(n= 29) .Serum Chlamydia pneumonia IgG(CPN-IgG) ,Helicobacter pylori IgG(HP-IgG) ,human cytomegalo virus IgG (HCMV-IgG) and hs-CRP tests were performed .Results CPN-IgG ,HP-IgG ,HCMV-IgG positive rates and the mixed infection positive rates increased sequentially from normal group to multi-branch group .There were significant differences of CPN-IgG ,HP-IgG ,HCMV-IgG and hs-CRP contents among the 4 groups (P<0 .05) .Logistic analysis showed that CPN-IgG ,HP-IgG and HCMV-IgG were dangerous factors to coronary artery lesion . Conclusion Chronic infections of three microorganism might affect the development of coronary artery lesion .

Objective To investigate the effects of HRT on endometrium of postmenopausal women.Methods 53 cases of postmenopausal vaginal bleeding(PMB),from Jan,1995 to Dec.1999 treated by HRT were selected to make a comparison with the other 60 cases of PMB without HRT during the corresponding period.Both groups had integrated ultrasonic and pathological data and getting information from succedent inspection.Results The rates of the endometrial carcinorma incidences that happen in the HRT group were non-HRT group were 5 66% and 8 33% respectively,which had little significant.While the occurring rates of inflammation were 1 89% and 16 67% respectively,a significant difference between the both existed here.Conclusions With HRT,the various symptoms of post menopause women can be efficiently improved.It is safe and effective in short term.But a close monitoring is absolutely necessary for its long term effect(5 years or more).

AIM:To investigate the aberrant methylation in the promoter of p16 in plasma,sputum,bronchoalveolar lavage fluid(BALF),pleural effusion and biopsy specimens from suspected lung cancer patients and to evaluate the clinical significance in the early diagnosis of lung cancer.METHODS:Using methylation specific PCR(MSP)for the detection of promoter methylation of p16 gene in plasma,sputum,BALF,pleural effusion and biopsy specimens from suspected lung cancer patients.RESULTS:Of the 67 cases of suspected lung cancer patients,42 were proved by pathology.The positive percentages of p16 gene promoter methylation of the lung cancer patients are as follows:52.4%(22/42)in plasma,47.6%(20/42)in sputum,59.5%(25/42)in BALF,71.4%(10/14)in pleural effusion and 61.9%(26/42)in biopsy specimens,respectively;while promoter methylation in p16 gene was found only one in plasma and one in pleural effusion in 25 patients with various benign lesions(P0.05).CONCLUSION:Detection of the aberrant methylation in the promoter of p16 gene in plasma,sputum,BALF,pleural effusion and biopsy specimens from lung cancer patients by MSP method is a kind of rising technology with development potential for lung cancer early diagnosis.

To study the antidepressant effects of piperine in chronic unpredictable mild stress (CUMS) rats and to explore the underlying mechanisms in the hypothalamic-pituitary-adrenal (HPA) axis.

Objective The aim of the study is to discuss the application value of HA330-Ⅱ microporous resin plasma adsorption in liver support and the treatment of complications of chronic severe hepatitis.Methods The treatment group has 41 patients of chronic severe hepatitis B,which were treated for 3 times by HA330-Ⅱ microporous resin plasma adsorption.We compared the improvement of symptom,the fadeamay and rebound of icterus,the change of hepatic encepllalOpathy and brain oedema,the change of blood routine test,blood ammonia level,blood-gas analyzing result,cruor index,inflammatory factors(IL-1b,IL-6,IL-8,TNF-α,etc.),side effects,etc.The control group has 37 patients of the same type.Results HA330-Ⅱ microporous resin plasma adsorptioin is partly effective for the improvement of symptom,improvernent rate 43.9%,and without new discomfort due to the treatment. It obtains some extent fadeaway of icterus which has a low rebound,reduce TBiL(17.83±3.65)% and there be no statistics difference of rebound.It lowers the blood ammonia level and improves the hepatic encephalopathy and brain oedema.It absorbs cytokine IL-8.Atthough it has some extent effect to albunfin,blood paltelet,haemoglobin.Conclusion HA330-Ⅱ microporous resin plasma adsorption has good application value in the treatment of chronic severe hepatitis B.It is a new treatment choice of severe hepatitis.

OBJECTIVE To assess the pathogen features and risk factors among diabetic patients complicated by lower respiratory tract nosocomial infection.METHODS A retrospective study was carried out to survey the clinical data of diabetic patients complicated by lower respiratory tract infection during from 2002 to 2005.RESULTS The main responsible pathogens were Gram-negative bacteria,their rate was 54.5%.While the rate of Gram-positive bacteria was 35.7 %.The rate of fungi was 9.8%.The risk factors of nosocomial infection included:old age,high level of blood sugar,consciousless status,longtime usage of antibiotics,oxygen inhalation and other aggressive manipulations.CONCLUSIONS In diabetic patients with lower respiratory tract infection,the incidence and mortality were all onrelatively high level.They must be given to pay attention.The chief pathogens were Gram-negative bacteria or fungi.So we should strengthen supervision and avoid risk factors,which are the keys in saving critical diabetic patients.

Objective: To investigate the role of Bcl-XL siRNA in sensitizing ovary cancer cells for TRAIL-induced apoptosis and the underlying mechanisms.Methods: Western blotting analysis was performed to confirm whether Bcl-XL siRNA could effectively down-regulate Bcl-XL protein after SKOV3 cells were transfected with Bcl-XL siRNA and then the cells were treated with TRAIL.Flow cytometry analysis and cell counting were used for assessment of apoptotic rate and survival rate,respectively.Western blotting analysis was performed to determine the changes of apoptosis-related protein in SKOV3 cells.Results: Compared with control group,Bcl-XL siRNA transfection effectively down-regulated the expression of Bcl-XL protein and suppressed the growth of SKOV3 cells;the suppression peaked at 96 h after transfection,being 43.9% that of the control group(P

Aim To prepare soluble global human C1 q and tumor necrosis factor related protein-2 in Escherichia coli. Methods Recombinant expression plasmid was transformed into strain BL21-codonplus (DE3),and the recombinant protein of Trx-gH2 was expressed by IPTG induction and then purified by Ni-NTA affinity and gel filtration chromatography.Results The purified recombinant Trx-gH2 was shown to be active under in vi-vo and in vitro assay conditions.Conclusion Active recombi-nant global hCTRP2 is efficiently prepared from Escherichia coli protein expression system.

Objective To study the correlation between coronary lesion and Cystatin C (CyC),Nitric Oxide (NO)and Super oxide dismutase,accumulate the clinical experience in prevention and diagnose of Coronary Heart Disease (CHD)by analy-zing the contents of serum Cystatin C (CyC),Nitric Oxide and Superoxide Dismutase in patients with coronary lesion.Meth-ods According to their severity of coronary artery lesion,all cases were divided into four groups:Normal compared group (40 cases);Simple branch pathological group (44 cases);Double branch pathological group (43 cases):Multi-branch patho-logical group (35 cases).All cases were tested CyC,NO,SOD and hs-CRP in serum.Results The level of CyC and hs-CRP were increased gradually from normal group to multi-branch group.The level of NO and SOD were decreased gradually from normal group to multi-branch group.There were significant differences the levels of CyC,NO,SOD and hs-CRP among the four groups.Coronary lesion Gensini in the CHD patients had significant positive relationship to the level of CyC or hs-CRP respectively (r=0.473,0.429),had significant negative relationship to the level of NO or SOD respectively (r=-0.356, 0.384)(P<0.05).CyC in the CHD patients had significant positive relationship to the level of hs-CRP (r=0.458),had sig-nificant negative relationship to the level of NO or SOD respectively (r=-0.426,0.484,P<0.05).Conclusion By aggra-vation of coronary artery lesion,the level of CyC increased,reduced the contents of NO,SOD,aroused endothelial dysfunc-tion,induced occurrence and aggravation of coronary artery lesion.CyC,NO and SOD play important mark in the assistant diagnosis of the disease.
