Objective To explore the interference situation of several diseases in the detection of treponema pallidum antibody by chemiluminescence method.Methods One hundred and ten samples of 9 kinds of different infectious diseases and 200 clinical random samples were collected.Three hundreds and ten samples were simultaneously detected by using the Abbott ARCHITECT i2000 automatic chemiluminescence immunoassay analyzer and matched reagents,and the Roche E602 automatic chemiluminescence instrument and its matching reagent.The samples of inconsistent results were confirmed by the gelatin particle agglutination test (TPPA).Results There were 5 samples with inconsistent results detected by two instruments,5 samples confirmed by TPPA were negative,and 4 cases were the samples of multiple myelome.Conclusion (1)Abbott ARCHITECT i2000 and Roche E602 have a good consistency in detecting treponema pallidum antibody;(2)for the patients of multiple myeloma,the interference may exist in detecting treponema pallidum antibody by chemiluminescence method,which may cause false positive results and needs to be vigilant in our daily work.

Purpose:To study the malignant probability of a solitary thyroid nodule,probable risk factor,the status of B-mode ultrasonography,computed tomography,fine needle aspiration and frozen section in the operation and other adjuvant examination in the diagnosis.Methods:In the retrospective analysis of 902 cases of solitary thyroid nodule treated by surger- y and diagnosed by pathology in the Cancer Hospital of Fudan University from March 1998 to May 2001,we analyzed the value of B-mode ultrasonography,computed tomography,fine needle aspiration and frozen section in the operation and com- pared them with the final pathological conclusion.Results:This disease occurred mostly in 20～50 years old women,while the malignant nodules occurred more frequently in men(P50 years) (P50 years) is a risk factor.B-mode ultrasonography can be used as routine preoperative examination.CT is valuable in the cases with metastasis to neck lymph nodules.With FNA the pathological diagnosis of the nodule suspected to be malignant can be made preoperatively.

Objective To examine expression of PTEN gene in ovarian cancer cisplatin-sensitive cell line OV2008 cells and cisplatin-resistant cell line C13K cells,and evaluate the effect of wild-type PTEN gene on reversing cisplatin-resistance of C13K cells and underlying mechanisms.Methods The expression of PTEN mRNA and protein in OV2008 and C13K cells were detected by semi-quantitative RT-PCR and western blot.Recombinant eukaryotic expression plasmid containing human wild-type PTEN gene was transfected into C13K cells by lipofectamine 2000.The expression of PTEN mRNA was monitored by RT- PCR and the expression of PTEN,protein kinase B(AKT),phospho-AKT(p-AKT)protein were analyzed by western blot in PTEN transfected and untransfected C13K cells.Proliferation and chemosensitivity of cells to cisplatin were measured by methyl thiazolyl tetrazolium(MTT),and cell apoptosis was detected by flow cytometry after treatment with cisplatin.Results(1)The expression of PTEN mRNA and protein(1.02 ?0.05,1.02?0.07)in OV2008 cells were significantly higher than those in C13K cells,which were 0.45 ?0.03 and 0.55?0.03 respectively(P

ObjectiveUsing large sample clinical study to reevaluate the safety and efficacy of recombinant human growth hormone(ANSOMONE) in treating pediatric growth hormone deficiency(GHD).Methods1012 cases were administered with ANSOMONE at a dose of 0.1 IU · kg-1 · d -1 in bedtime for 6 months.The alteration of mean height,growth rate,height standard deviation scores,bone age,and anti-GH antibody and occurrence of adverse effects were observed.ResultsThe growth rate was promoted from ( 2.50 ± 0.85 ) cm/year to ( 13.44 ± 4.27 ) cm/year,the net growth rate was( 10.94 ±3.69)cm/year.There was significant difference between the pre-treatment and post-treatment patients ( P ＜ 0.01 ).The post-treatment anti-GH antibody positive rate was 13.34％,which had no obvious effect on the efficacy.Few patients exert transient inflammation reactions,which disappeared with any treatment.ConclusionANSOMONE had significant efficacy,and could promote the height increase obviously.It had good safety without any obvious side effect and early-maturing effect.

Objective To explore the application value of DOSE index score in the peitients with chronic obstructive pulmonary disease.Methods 122 cases of plateau COPD patients were followed up for 12 months,and we recorded and analyzed the patient's health and life.We also recorde FEV 1 and DOSE scores of the patients with COPD,and record the COPD risk events,including the number of respiratory failure and death,and the times of hospitalization,total such confinement,outpatient expenses,hospitalization expenses,mMRC,and scored in the number of exacerbations,etc.Results The DOSE index score was negatively correlated with FEV1％ pred (r=0.73,P ＜ 0.05) for 122 COPD patients,and were positively correlated with mMRC (r=085,P ＜ 0.01),the annual number of exacerbations (r=0.71,P ＜ 0.01),respiratory failure (r=0.65,P ＜ 0.01),heart failure (r=0.50,P ＜ 0.01),number of outpatient service (r=0.12,P＜0.01),hospitalization time (r=0.70,P＜0.01),the totalsuchconfinement (r=0.66,P＜0.01),outpatient expenses (r=0.13,P＞ 0.13),hospitalization expenses (r=0.65,P＜0.01).ROC curve was used to analyzed the cut-off point and curve area of COPD DOSE index.Conclusion The DOSE index is a simple COPD assessment tools,and is closely related to the prognosis of patients and health.

OBJECTIVE:To study the effects of Xiaoruzeng capsule on the gastric acid and pepsin in rats. METHODS:Rats were randomized into a blank group (distilled water),a positive control group (3.6 mg/kg omeprazole ) and the groups of low, middle and high doses of Xiaoruzeng capsule [2.25,4.5,9.1 g(crude drug)/kg]. These groups were respectively marked as groups A,B,C,D and E,with 10 rats in each group. All the rats were given corresponding drugs,ig,for consecutive 10 d. Their suc-cus gastricus was collected 3 h after the last administration,and determined for pH value with precision pH test strip and for free acidity and total acidity by acid-base neutralization titration method. The content and activity of pepsin were determined and calculat-ed with the test kit and microplate reader. The pathological change of the stomach was observed under the electron microscope. RE-SULTS:Compared with group A,groups B,C and D had higher pH value of succus gastricus;groups C,D and E had lower free acidity;groups B,C and D had lower total acidity,group E had higher total acidity;groups B,D and E had lower activity of pep-sin;and group C had higher content of pepsin. Compared with group B,group D had lower pH value of succus gastricus;group C had lower total acidity;group E had higher acidity;and groups C,D and E had higher activity of pepsin. There was statistical sig-nificance(P<0.01 or P<0.05). Gastric mucosal erosive haemorrhage was noted in three rats in group E,and other groups demon-strated no obvious pathological change. CONCLUSIONS:Low dose of Xiaoruzeng capsule can slightly inhibit the gastric acid in rats,but will not effect the activity of pepsin.
