Objective To study the subclavian artery angiography for hemoptysis and its clinical value.Methods Thirty-eight cases of hemoptysis undertook subclavian artery angiography after embolization of bronchial arteries and branches of thoracic aorta. Group A: 4 recurrent cases underwent subclavian artery angiography (unilateral: n =2, bilateral: n =2). Group B: 16 cases underwent subclavian artery angiography according to the manifestation on X-ray and CT (right: n =10, left: n =6). Group C: 18 cases underwent bilateral subclavian artery angiography.Results of subclavian artery angiography were divided into three classes: normal(-),chaotic and hyperplasia of small branchi vessels(+),obviously bleeding (++).Some of the obviously bleeding cases were embolized and analysed for clinical efficacy and complications. Results Bleeding cases accounted for 63.2%(24/38)and bleeding subclavian arteries accounted for 50%(29/58), including(++):37.9%(22/58) and(+): 12.1%(7/58). Positive rate of chronic fibro-cavitary pulmonary tuberculosis was the highest. Bleeding sites were coincided with lung lesions. Twelve cases were embolized with the immediate cessation rate of hemoptysis reaching 100%. Eight cases with long-term follow-up showed 5 cured, 1 with significant effect and 2 recurrent. The complications occurred with fever, vomiting, chest pain, hiccup and dyspnoea.Conclusions Subclavian artery angiography has important clinical value in artery embolization for hemoptysis, especially for lesions in the upper lobes of lungs and with more fruitful result for chronic fibro-cavitary pulmonary tuberculosis.

OBJECTIVETo observe the clinical effect of Huikangling Tablet (HT, extracted from Scabrous Patrinia root) on peripheral blood micrometastasis of differentiated thyroid carcinoma (DTC) patients.

METHODSTotally 87 DTC patients with positive micrometastasis were randomly assigned to the treatment group (45 cases) and the control group (42 cases). DTC endocrine inhibition treatment standards were executed in all patients. They all took levothyroxine sodium (50 microg/tablet, from low dose, 25 microg each time, once per day, 0.5 h before breakfast), and its dosage was gradually added one week later. The dosage was adjusted according to tested results of TSH combined recurrence risk stratification and endocrine suppression induced adverse reactions risk stratification. Patients in the treatment group took HT (0.4 g per tablet, 3 tablets each time, three times per day for a total of 12 weeks) combined TSH suppression therapy, while those in the control group only received TSH suppression therapy. Peripheral micrometastatic cytokeratin 19 (CK19) and polymorphic epithelial mucin1 (MUC1) were detected by FCM at week 4 and 12. Meanwhile, distant metastasis and adverse reactions were observed.

RESULTSAfter 4-week treatment positive micrometastasis was shown in 18 cases (40%) of the treatment group and 29 cases (69%) in the control group with statistical difference (chi2 = 5.68, P < 0.05). After 12-week treatment positive micrometastasis was shown in 7 cases (15.6%) of the treatment group and 17 cases (44.7%) in the control group with statistical difference (chi2 = 8.49, P < 0.01). Pulmonary metastasis occurred in 2 cases and bone metastasis in 1 case of the control group at follow-ups. Cervical lymph node metastasis without accompanied recurrence of thyroid cancer occurred in one case of the treatment group. No obvious liver or renal abnormalities occurred.

CONCLUSIONHT inhibited peripheral blood micrometastasis of DTC patients and its mechanism needed to be further studied.

Contemporary hospital information systems normally contain multiple applications,which are traditionally deployed as one application per server.More servers in the system will incur high system costs,low server efficiency and poor management and maintenance.The information system reform project of Wuxi Maternal and Child Health Hospital called into play the virtualization based on VMware.The project brought forth a number of merits,namely sizably raising efficiency of servers integration,simplifying server group management,reducing cost and promoting hospital informationization.

Objective To investigate whether macrophage-activating lipopeptide-2 ( MALP-2) in-duces the expression of heme oxygenase-1 ( HO-1 ) in THP-1 cells and its possible mechanism .Methods Human monocyte cells THP-1 were cultured in vitro and then were incubated with various concentrations (0, 0.01, 0.1, 1.0 or 5.0 ng/ml) of MALP-2 for 16 h, or were stimulated by 5.0 ng/ml MALP-2 for different length of time (0 h, 4 h, 8 h, 12 h, 16 h or 24 h).The expression of HO-1 at mRNA and protein levels were detected by real-time PCR analysis and Western blot assay .The enzyme activity of HO-1 was detected by colorimetric analysis.THP-1 cells were pre-incubated with 30 μmol/L of SB203580, PD98059 and SP600125 for 30 min and then were cultured with 5.0 ng/ml MALP-2 for 16 h to investigate the role of mito-gen-activated protein kinases (MAPKs) signaling pathway in HO-1 production.After incubating THP-1 cells with 5.0 ng/ml MALP-2 for different periods of time, NF-E2-related factor 2 (Nrf2) protein was detected by Western blot assay to study the effects of Nrf2 pathway on MALP-2-induced HO-1 expression.Nrf2 and HO-1 proteins were measured by Western blot assay after transfecting THP-1 cells (1×106/well) with Nrf2 siRNA at a final concentration of 100 nmol/L.Results MALP-2 enhanced the expression of HO-1 at mRNA and protein levels as well as the enzyme activity of HO-1 in THP-1 cells in a concentration-dependent manner.The expression of HO-1 protein induced by MALP-2 was significantly inhibited by 30 μmol/L MAPKs specific inhibitors ( SB203580 , PD98059 and SP600125 ) .MALP-2 induced Nrf2 translocation at a concentration of 5.0 ng/ml.The expression of Nrf2 and HO-1 proteins were significantly decreased in Nrf 2 siRNA-transfected THP-1 cells.Conclusion MAPKs and Nrf2 signaling pathways were involved in the MALP-2 induced HO-1 expression .

Objective:To observe the molecular mechanism involved in expression of hemeoxygenase -1 (HO-1) induced by a macrophage-activating lipopeptide-2 (MALP-2).Methods:THP-1 cells were cultured in vitro and stimulated by MALP-2 for 12 h, expression of HO-1 was detected by Western blot .TLR2 and TLR6 neutralizing antibodies incubation , dominant negative plasmids transfection were used to assess the functional of TLR 2,6 in mediating HO-1 expression.Phosphorylation of c-Src and Akt were detec-ted by Western blot, and c-Src siRNA and PI3K inhibitor LY294002 were used to investigate the role of c-Src and PI3K in HO-1 ex-pression.Results:MALP-2 induced c-Src phosphorylation , and TLR2 and TLR6 neutralizing antibodies , or their dominant negatively plasmids could abrogate this effect .In addition, siRNA of c-Src could decrease the phosphorylation level of Akt , and the PI3K inhibi-tor could inhibit HO-1 expression.Conclusion: MALP-2 can induce THP-1 cells expression of HO-1 through TLR2,6/c-Src/PI3K pathways .

To investigate the therapeutic effects and associated complications of allogeneic peripheral blood stem cell transplantation (allo-PBSCT). 40 patients with various malignant hematopoietic diseases received allo-PBSCT. The preparative regimens were based on BUCY2 or modified BUCY2. The acute graft-versus host disease (aGVHD) was prevented by cyclosporin A and short-term MTX regimen in all patients. Two patients from donors with one fully mismatched HLA on DRB1 locus and 4 from unrelated donor also administered Zenapox (CD25 MAb) at dosage of 1 mg/kg every day on the day before transplantation and day 4 after transplantation. These 6 patients were also treated with mycophenolate mofetil (MMF). Transfusion of the donor cells: The median of the transfused nucleated cells was 5.38 x 10(8)/kg and that of the CD34+ cells was 7.8 x 10(6)/kg respectively. All the patients gained hematopoietic reconstruction except one who died of infection before engraftment. Seven patients got II degrees-IV degrees aGVHI) and the incidence was 17.5%. Fourteen patients got cGVHD and the incidence was 53.8% in the patients who survived over 6 months. Twenty-eight patients had fever or other characteristics of infection. The median follow-up time was 13.8 months. The incidence of transplantation related mortality (TRM) was 17.5% and 2 patients relapsed (5.0%). It was concluded that allo-PBSCT can reconstruct hematopoiesis quickly and is a favorable therapeutic method for leukemia.
