Objective To study the pregnancy opportunity,treatment of complications,time of ending pregnancy and treatment during and after pregnancy in patients with systemic lupus erythematosus(SLE).Method Prospective study on pregnant patients with SLE was carried out between 2000 and 2003 in Qingdao Municipal Hospital.There were total 29 patients enrolled,all which didn't have cytotoxic drugs at least six months before conception,among whom 23 patients'disease were under control over one year and had low-dose glucocorticoids before pregnancy,two had disease activity under control by mid-and high-dose glucocorticoids within one year and have been pregnant without the direction of the doctor,four new onset during the pregnancy.Results All patients had flares during pregnancy or had multi-complications,10 cases had pregnancy hypertension syndrome,six cases had heart failure during the late pregnancy,three had extensive interstitial lung disease during the late pregnancy.All patients stopped the pregnancy at 30~37 weeks,the total 29 live infants had neither neonatal lupus nor maternal-fetal death.Conclusion The maternal-fetal safety can be increased significantly when disease activity was controlled over one year.Glucocorticoids should be applied when disease flared during pregnancy and postpartum is the key of success,Stop as pregnancy when there are complications in order to improve maternal-fetal safety.

Objective: To study the effect of HSVtk/GCV system on ascites tumors. Methods: Using the methods of modified XTT assay, animal experiment, transmission electron microscopy (TEM ) and flow cytometric ( FCM) assay. Results: The sensitivity of P388tk cell was about 37-fold than that of their patental P388 cell. Furthermore we found P388tk cells exhibited potent bystander killing. In vivo , the growth of tumors, which were produced by injecting P388tk cells or a mixture of 50% P388tk cells and 50% P388 cells into DBA/2 mice, was inhibited , furthermore mice survival periods were prolonged contrasted to control groups. Conclusion: HSVtk/GCV suicide gene system could effectively killed the HSVtk-gene-positive P388tk cells and nearby HSVtk-gene-negative cells by the bystander effect in vitro and in vivo.

Objective To study the clinical features of the extra exocrine gland symptoms of primary Sjgren syndrome(PSS) in elderly people. Methods Clinical data of 106 cases of elderly and 120 cases of non elderly PSS were collected and analyzed. Results A total of 203 cases(89 8%, 203/226) manifested symptoms of extra exocrine glands, in which elderly and non elderly groups accounted for 106(100 0%) and 97(80 8%), respectively. The occurrence rates of arrhythma due to hypokalemia, peripheral neuritis(P0 05). Conclusions The common symptoms of PSS in patients, especially the elderly patients, are extra exocrine gland manifestations as the main complaints though the PSS is a systemic disease. These must be differenciated in order to avoid misdiagnosis.

Objective To study the relationship between sICAM 1,sVCAM 1,TNF ?,TNFR Ⅰ,TNFR Ⅱ and pathogenesis of vasculitis.Method The serum levels of TNF ?,TNFR Ⅰ,TNFR Ⅱ,sICAM 1 and sVCAM 1 were detected by ELISA and their levels between patients with vasculitis and controls were compared.Results Compared with the controls,the serum level of TNF ? was lower,the levels of TNFR Ⅰ,sICAM 1 and sVCAM 1 were higher in the patients with vasculitis,and there was no difference of TNFR Ⅱ between the two groups.Conclusion The low level of TNF ? suggests that this factor may not play a role in these patients,or its role was counteracted by its receptors—sTNFR,whose level was higher in patients with vasculitis.sICAM 1 and sVCAM 1 may play a significant role in the pathogenesis of vasculitis.

Objective To investigate the factors related to outcome (recovery of motor, activities of daily living, and balance) of stroke patients. Methods 67 stroke patients with hemiplegia were evaluated with the Ueda Classfication of upper and lower limbs function, Functional Independence Measure (FIM), Berg balance scale (BBS) before and after treatment. The scores of all the assessment were as the dependent variable respectively, and regression analyzed with the factors possiblely related to the outcome. Results The positive factors for lower limbs function included rehabilitation intervention, time of rehabilitation, and hypercholesterolemia; while the negative factors were body mass index (BMI), and damage of superficial sensibility. The positive factors for upper limbs function were rehabilitation intervention and time of rehabilitation; while the negative factors were BMI, dysphagia, damage of superficial sensibility, and frequency of attack. The positive factors for hand function were rehabilitation interventions and interval from diagnosis to rehabilitation, while the negative factors were the muscle tension, incontinence, and frequency of attack. The positive factors for FIM were the rehabilitation intervention, while the negative factors were BMI, incontinence, hypercholesterolemia, gender and residence status. The positive factors for BBS were the rehabilitation intervention, while the negative factors were BMI, frequency of attack, and hyperglycemia. Conclusion Rehabilitation promotes the recovery of stroke patients, but the BMI may block it.

Objective To investigate the effects of reactive oxygen species (ROS) inhibition on the down-regulation of adiponectin (ADPN) in mouse 3T3-L1 adipocytes by advanced glycation end-products (AGEs).Methods AGEs were prepared for incubating with cell.3T3-L1 preadipocytes were cultured in vitro and differentiated into mature adipocytes.Cell differentiation and lipid accumulation were determined by oil red O staining.After being intervened with AGEs,2',7'-dichlorofluorescein diacetate (DCFH-DA) was used as a reactive oxygen species (ROS) capture agent and the fluorescent intensity of 2',7 '-dichlorofluorescein (DCF) was detected by flow cytometry.Adiponectin expression under AGEs in 3T3-L1 adipocytes pretreated with N-acetyl-L-cysteine(NAC) or not was detected by real-time fluorescent PCR and ELISA.Results The level of ROS in 3T3-L1 adipocytes treated with AGEs was increased.mRNA and protein of ADPN were down-regulated.After inhibition with ROS,mRNA and protein expressions of ADPN injured by AGEs were ameliorated.Conclusion Exposure of 3T3-L1 adipocytes to AGEs induces oxidative stress in vitro,which decreases the expression of ADPN,and causes functional impairment of adipose cells and insulin resistance.

Objective:To construct recombinant adenovirus vector Ad5-CCL20,and detect the expression of CCL20 after Ad5-CCL20 transfected colon cancer cells CT-26.Methods:Genes encoding CCL20 was obtained from original plasmid double-digested with EcoR I/Sal I enzymes.The CCL20 DNA segments were linked into pDC316 to recombine shuttle plasmid pDC316-CCL20.After genome sequencing,we take shuttle plasmid pDC316-CCL20 and plasmid backbone pBHGIox_E1,3Cre co-transfecting 293T cells in mediation of liposome.The constructed recombinant adenovirus vector was named Ad5-CCL20.Lastly,after Ad5-CCL20 transfected CT-26 cells in vitro,the expression of CCL20 at different time points (12h,24h,36h and48h)was detected by Western blot and Elisa.Then,Culture supernatant was added into iDC and mDC to evaluate the chemotactic activity of CCL20.Results:The recombinant adenovirus Ad5-CCL20 were successfully constructed.The expression of CCL20 was detected by Western blot and Elisa.The level of CCL20 expression was increased with prolonged incubation of the infected CT-26 cells.Chemotaxis experiments show that the chemokine CCL20 had chemotactic activity to the iDC and mDC,but more obviouly for iDC (P＜0.05).Conclusion:The construction and obtain of recombinant adenovirus vector Ad5-CCL20 provide a new method for developing tumor immunotherapy.

The abdominal visceral fat content in obese SD rats induced by high fat diet for 10 weeks was significantly higher than that in control group [(26±6 vs 13±3)g,P<0.01] ,along with increased CRP mRNA expression in abdominal visceral fat (0.901±0.085 vs O. 402±0.036, P<0.01). As compared with normal control group, in the high fat group the concentrations of CRP in portal vein [(743.8±95.8 vs 558.3 ±118.3) mg/L, P<0.01] and peripheral vein[(596.3±38.9 vs 485.8±30.2) mg/L,P<0. 05] were higher. The concentration of CRP in portal vein was significantly higher than that in peripheral vein in high fat diet group(P<0.01) ,but this was not evident in control group. These results suggest that the increased CRP expression in visceral adipose tissue may partially account for the elevation of serum CRP in obesity.

Objective · To explore family medical intervention model of senile dementia with behavioral and psychological symptoms. Methods · Four streets of Changning District in Shanghai were randomly selected and subjects were enrolled according to the inclusion criteria, who were randomly divided into the intervention group (n=71) and control group (n=70). The intervention group received door-to-door service from psychiatric doctors, given drug treatment and psychological intervention. Subjects were evaluated by several scales, including Behavioral Pathology in Alzheimer's Disease Rating Scale (BEHAVE-AD), Mini-Mental State of Examination (MMSE), Activity of Daily Living Scale (ADL), Quality of Life-Alzheimer's Disease (QOL-AD), and Generic Quality of Life Inventory-74 (GQOLI-74), at baseline and by the end of 6 months and 12 months. Results · ① There was no significant difference in the total scores and all factor scores of BEHAVE-AD between the two groups before intervention (P>0.05). Repeated measures analysis of variance revealed a significant main effect of time (P<0.001). The between-group effect was significant in the total scores of BEHAVE-AD and the factor scores of affective disorder, anxiety and terror (P<0.001). The interactive effect of time×group was significant in the total scores of BEHAVE-AD and the factor scores of delusion and affective disorder (P<0.05). ② Intergroup comparison of the BEHAVE-AD scores indicated that by the end of 6 months, factor scores of hallucination, circadian rhythm disorder, affective disorder, anxiety and terror of the intervention group were remarkably better than those of the control group and the differences were statistically significant (P<0.01). By the end of 12 months, total scores of BEHAVE-AD, and factor scores of delusion, conduct disorder, affective disorder, anxiety and terror of the intervention group were remarkably better than those of the control group and the differences were statistically significant (P<0.01). ③ There was no significant difference in the scores of MMSE, ADL, QOL-AD and GQOLI-74 between the two groups before intervention (P>0.05). Repeated measures analysis of variance revealed a significant main effect of time (P<0.001). The between-group effect was significant in the scores of MMSE and QOL-AD (P<0.001). The interactive effect of time×group was significant in the scores of MMSE, ADL, QOL-AD, and GQOLI-74 (P<0.05). ④ Inter-group comparison of MMSE, ADL, QOL-AD, and GQOLI-74 scores indicated that by the end of 6 months, scores of MMSE of the intervention group were remarkably better than those of the control group and the differences were statistically significant (P<0.05). By the end of 12 months, scores of MMSE, ADL, QOL-AD, and GQOLI-74 of the intervention group were remarkably better than those of the control group and the differences were statistically significant (P<0.05). Conclusion · The family medical intervention model of door-to-door services from psychiatrists integrating multidisciplinary team is effective to attenuate the mental and behavioral symptoms of senile dementia patients, and can improve the quality of life of patients and caregivers. The effect of persistent implementation will be more remarkable.
