OBJECTIVE To observe the protective effect and underlying mechanism of total ginsenosides (TG) on bleomycin-induced pulmonary fibrosis. METHODS Intratracheal instillation of bleomycin 5 mg · kg-1 was conducted to establish a pulmonary fibrosis mouse model. Kunming mice(1/2 males and 1/2 females)were randomly divided into sham-operation(Sham),model,total ginsen?osides 40,80 and 160 mg·kg-1 and prednisone acetate(5 mg·kg-1) groups. After 28 d administration,the histopathological changes in the lung were analyzed by hematoxylin eosin(HE)and Masson staining. The exprssion of alpha smooth muscle actin(α-SMA)in the lung was detected by real-time PCR. The content of hydroxyproline(HYP)and glutathione(GSH),level of total antioxidant capacity(T-AOC)and hydroxy radical(·OH),activity of myeloperoxidase(MPO)and nitric oxide synthase(NOS)in the lung were detected by corresponding kits. RESULTS Compared with the sham group,the pulmonary indexes in model group were significantly increased(P<0.01),alveolitis and pulmonary fibrosis were obvious. The mRNA expression ofα-SMA,content of HYP and · OH,activity of MPO and NOS were increased(P<0.05),but the content of GSH and T-AOC in model group was decreased(P<0.05). Compared with model group,the pulmonary indexes in TG 80 and 160 mg · kg-1 and prednisone acetate 5 mg · kg-1 groups were reduced(P<0.05),and the degree of alveolitis and pulmonary fibrosis was mitigated. The mRNA expression ofα-SMA,content of HYP and · OH, the activity of MPO and NO were decreased (P<0.05),while the content of GSH and T-AOC was increased(P<0.05). CONCLUSION TG can improve the degree of mice pulmonary fibrosis induced by bleomycin. The mechanism may be related to the increased antioxidant capacity of organisms.

BACKGROUND:Recent studies have shown that the large-dose regular insulin therapy used to control blood glucose levels can cause 50%of patients suffering from vascular, optic nerve and kidney complications. Previous results from authors exhibit that when al ogeneic hematopoietic stem celltransplantation is applied for treatment of leukemia, diabetic symptoms in patients disappear. Dose it prompt that al ogeneic hematopoietic stem celltransplantation is an effective therapy for treatment of diabetes mel itus? OBJECTIVE:To explore the feasibility of hematopoietic stem celltransplantation for treatment of diabetes mel itus. METHODS:A retrospective analysis was done regarding the data of patients with hematological diseases complicated with diabetes mel itus who underwent al ogenetic hematopoietic stem celltransplantation. Four patients with acute lymphocyte leukemia, chronic myelogenous leukemia, aplastic anemia, and myolodysplastic syndromes, respectively, were complicated with diabetes mel itus. Conditioning regimen was cyclophosphamide+total body irradiation protocol. Cyclosporin A and short-term methotrexate were used for graft-versus-host disease prophylaxis. Blood glucose was control ed by oral hypoglycemic drugs or insulin injections before transplantation. RESULTS AND CONCLUSION:Al the four patients were successful y engrafted. Fasting glucose level of the four patients recovered at 4-6 months after hematopoietic stem celltransplantation (without hypoglycemic drugs). One patient died of leukemia relapse after 12 months of hematopoietic stem celltransplantation. The other three patients had disease-free survival until the time of fol ow-up.

Objective To explore the inter-fraction setup errors and affecting factors from data of daily fan-beam megavoltage computed tomography(MVCT). Methods A total of 37consecutive NPC patients treated with tomotherapy were hospitalized during the period of February 2015 to September 2015. For each patient,one MVCT scan was obtained after conventional positioning ,online correction and tomotherapy delivery daily ,and the scans were put into the planning computed tomography to determine inter-fraction setup errors. The MPTV was calculated with the equation:MPTV=2.5∑+0.7σ(∑:systematic error;σ:random error). Results The average absolute errors of the inter-fraction were(2.102 ± 0.0406)mm,(1.490 ± 0.0348)mm,(1.306 ± 0.335)mm and(1.392 ± 0.0384)° at three dimensions. The total MPTV accounting for inter-error was 3.4675 mm,2.9795 mm,and 2.8885 mm. Gradual increases in both inter-fraction three-dimensional displacement were observed with time and treatment(P < 0.05). Univariate analysis revealed that weight loss and retraction of neck lymph nodes were affecting factors of set-up errors. Conclusions 3 mm margins uniformly expended from clinical target volume to planning target volume may not be suitable. The personalized margin should be adopted for the design of IMRT planning. Displacement increases as a treatment course is prolonged.

Objective To assess the clinical safety and effectiveness of transcatheter arterial embolization by using liquid medical glue ( FLA ) and super-selective catheterization technique in treating renal artery pseudoaneurysm. Methods During the period from Oct. 2009 to Jun. 2014, a total of 23 patients with angiography-proved renal pseudoaneurysm were treated with transcatheter arterial FLA embolization at authors’ hospital. The clinical data were retrospectively analyzed. A total of 28 pseudoaneurysms were detected in the 23 patients, which was caused by iatrogenic injury(18 cases, 21 lesions) or trauma(5 cases, 7 lesions). Super-selective catheterization with 3F micro-catheter was carried out. The micro-catheter was inserted into the parent artery of the pseudoaneurysm, which was followed by angiography. Once the pseudoaneurysm was confirmed by angiography, the mixture of FAL and iodized oil (1 ∶ 1) was injected into the pseudoaneurysm through the micro-catheter. The technical success rate, postoperative hematuria and renal function were determined. Results Successful embolization was achieved for all 28 pseudoaneurysms in 23 patients. The average volume of FAL used in embolization was 0.4 ml (0.2-1 ml). Ectopic embolization of the third-level vessel branches near the parent artery occurred in three cases , while no embolization of second-level vessel branch was observed. Persistent hematuria was seen in one patient even at two days after the treatment, whose pseudoaneurysm’s diameter was >2 cm, and embolization treatment with steel coil had to be performed, and bleeding stopped after the second treatment. During the follow-up period lasting for 3 months, no recurrence of hematuria was seen in the remaining patients. Mild elevation of serum creatinine after the treatment was observed in 4 patients. Conclusion The results of this study indicate that FAL together with the help of micro-catheter super-selective catheterization can effectively and reliably obstruct renal pseudoaneurysm with higher technical success rate and lower re-bleeding rate.
