Objective To study the clinical value of transbronchial arterial chemoembolization with MMC-li piodol or ADM-lipiodol mixture in the treatment of lung cancer.Methods In this study 32 cases with lung cancer,bronchial arteriography were adopted to identify the tumor-feeding branch.After perfusing 500～1000mg 5-Fu and 60 ～80mg CDDP through microcatheter,embolization with the mixture of 3 ～10ml lipiodol and 20mg MMC or 40mg ADM was performed.Results Short-term effectiveness;complete response(CR)was achieved in 1 case,while partial response(PR)in 19 cases,steady disease(SD)in 11 cases and process disease(PD)in 1 case.The total effectiverate (CR plus PR)was up to 62.5%(20/32).Complications included S cases of the chest pain and 2 cases of the chest wall epidermis pain,which were relieved after symptomatic management.1 case produced spinal injury,which was partially recovered after symptomatic management.Conclusion Transbronchial arterial chemoembolization with MMC-li piodol or ADM-lipiodol mixture has good short-term effect in the treatment of lung cancer.The procedure should be carried out carefully to avoid severe complications.

Objective To study the relationship between magnesium level in umbilical vein and mother′s peripheral blood with intrauterine growth retardation (IUGR) and fetal weight. Methods 39 pregnant women with IUGR were randomly divided into 3 groups: Group 1 (n= 14): The patients were treated with 10% glucose 500 ml + danshen compound 14 ml + low molecular weight dextran 500 ml iv; Group 2 (n= 14): in addition to the same treatment as in group 1, 25% magnesium sulfate 20 ml in 5% glucose 500 ml iv was given; Group 3 (n= 11): no treatment was given; and another 12 normal term delivery women were served as control. Magnesium concentration levels were determined in both maternal peripheral blood and their fetal umbilical vein. Results Maternal serum magnesium level was higher in Group 2 (1 06?0 09) mmol/L than that in Group 1 (0 69?0 05) mmol/L (P

Objective To observe the injury effect of ionizing radiation on bone marrow derived c-kit+ cells.Methods Via-bility of c-kit+ cells was measured by bioluminescence;the level of c-kit+ cells reactive oxygen species was measured by DCFH-DA, the ability of colony-forming units was reflected by CFU-GM;proliferation and apoptosis of c-kit+ cells were measured by flow cy-tometry;the variation of pathway was detected by arrays of gene chip.Results Compared to control group(0 Gy).It had a decrease of c-kit+ cells′cell viability and the ability of colony-forming units after the cells receipt irradiation with the dose of 1 Gy and 4 Gy;and the level of cell reactive oxygen species,ratio of apoptosis cells increased.After 1 Gy irradiation exposure,the ratio of prolifera-tion(S/G2/M phase)cells increased compared to control group.However,when the c-kit+ cells were receipt 4 Gy irradiation expo-sure,the ratio of proliferation(S/G2/M phase)cells decreased.After 4 Gy irradiation exposure,the up-regulate genes contained Srxn1,Psmb5,Cdkn1a,Smc1b,Bcl2l1,Lrdd and so on;the down-regulate genes contained Mpo,Mtf1,Chek1,Rcc1 Ebag9,Ciapin1 and so on.Conclusion There was injury effect of ionizing radiation on c-kit+ cells,and it could induce variation of many pathways.

ObjectiveTo evaluate the efficacy and safety of hydroxychloroquine(HCQ) in pregnant patients with systemic lupus erythematosus (SLE).Methods Twenty-four pregnant patients with SLE treated with HCQ during pregnancy from May,2006 to February,2011 were studied retrospectively.All babies were followed up during early infancy for growth development.ResultsOf them,22 patients were treated with HCQ throughout the whole pregnancy with no lupus flare occurred in 21 patients (95.4％),while temporary discontinuation of HCQ precipitated a flare of disease in two patients.Three patients ( 12.5％ ) had premature delivery,and pregnancy induced hypertension happened in 3 patients (12.5％ ).No congenital abnormalities occurred and mean follow-up of 26 months ( range 1 - 47 months) revealed no abnormalities in these children.Conclusion Our findings reinforce the safety of HCQ therapy during pregancy and HCQ should probably be maintained throughout the pregancy in patients with SLE.

Objective To discuss the application of cerebrovascular intervention technique in evaluating the correlation between cerebral venous sinus and idiopathic intracranial hypertension (ⅡH).Methods The clinical data,including complete related clinical signs and symptoms,laboratory results,magnetic resonance venography (MRV) findings,etc.,of 13 ⅡH patients were retrospectively analyzed.Under local anesthesia whole brain DSA was performed,and superselective catheterization of venous sinus was accomplished to perform sectional pressure measurement of sagittal sinus,transverse sinus,sigmoid sinus and jugular vein.Results Cerebral DSA examination revealed that venous sinus stenosis or occlusion was seen in 10 patients (76.9％),including transverse sinus (n=6),sigmoid sinus (n=3),and transverse sinus together with sigmoid sinus (n=l).Superselective pressure neasurement of venous sinus showed that the pressure difference between the two ends of the narrowed venous sinus was up to 120-580 mmH20 in these 10 patients.In 8 patients (61.5％,8/13) the venous sinus stenosis and/or occlusion might be implicated in the occurrence of ⅡH,in 2 patients (15.4％,2/13) the venous sinus stenosis might be secondary to ⅡH,and in 3 patients (23.1％,3/13) the venous sinus stenosis might bear no relationship to ⅡH.Conclusion Cerebrovascular interventional angiography combined with superselective pressure measurement of venous sinus can clearly identify the relationship between ⅡH and venous sinus

Objective To investigate the prevalence and risk factors of Toxoplasma gondii infection among key populations in Wuxi City,Jiangsu Province,so as to provide evidences for developing preventive and control interventions for T. gondii in-fection. Methods A questionnaire was designed to conduct face-to-face interviews to HIV/AIDS carriers/patients,tumor pa-tients,pregnant women and pet breeders. The blood samples were collected to test anti-Toxoplasma IgM and IgG antibodies by using ELISA method. Results Totally 404 participants were investigated,and 38 were positive in testing T. gondii antibodies (9.4%),and among these,37(97.4%)were IgG positive and 1(2.6%)was IgM positive. The multivariate logistic regression indicated that age,regularly contacting cats/dogs and being HIV positive were associated with the infection of T. gondii(OR=2.1,2.6 and 2.3,all P < 0.05). Breeding pets,being HIV positive and being tumor patients were more likely to infect T. gondii than being pregnant(OR = 1.5,8.1 and 2.8,all P < 0.05). Conclusion The high infection rate of T. gondii is observed among key populations in Wuxi City,so that the effective measurements should be taken to enhance the intervention among key popula-tions including immunocompromised people,pet breeders or people having bad dietary habits of eating raw food.
