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 explore the curative effect of acyclovir combined with pidotimod in treatment of adult varicella.Methods 80 adult patients with varicella in our hospital were randomly divided into two groups.40 cases in group A were intravenously injected acyclovir.40 cases in group B were intravenously injected acyclovir combined with oral pidotimod.The time of herpes blisters drying and completely crusted were observed in two groups.Results The time of herpes blisters drying and completely crusted of B group was shorter than A group.And the differences were statistically significant(P ＜0.01).Conclusion Acyclovir combined with pidotimod in treatment of adult varicella can significantly shorten the healing time,and show better curative effect than single use of acyclovir.

Objective To investigate the effects of advanced glycation end products (AGEs) on NADPH oxidase expression in rats′ pancreatic cells. Methods Isets of rats were isolated and intervened with AGEs for certain times (2, 12, 24, 48 h). The Nox2 mRNA expression was assayed by reverse transcription polymerase chain reaction (RT-PCR) and Real-time PCR. NADPH oxidase activity was detected by lucigenin-enhanced chemiluminescence. Results Nox2 mRNA level was 1.75, 2.31-fold higher in AGEs intervened group than control at 12 h and 24 h respectively. The NADPH oxidase activity was increased by AGEs stimulation in a time dependent manner. A distinct peak was at 24 hours and then with a decline , which is still higher than that of the control. Conclusion Exposure of rat islet to AGEs induces NADPH oxidase expression and leads to injury of islet.

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 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.
