No patient showed acute haemolysis in the ABO incompatible group. The median time of blood type transformation was 40 2?25 days. The median time for recovery of normal WBC and Plt in ABO incompatible groups was 10 days longer than that in the ABO compatible group. The number of patients with Hb

To investigate the effects of ischemia-reperfusion on the levels of nitric oxide and nitric oxide synthase isoforms (nNOS and iNOS), rat organotypic hippocampus slice were cultured in vitro and subjected to ischemia by oxygen-glucose deprivation (OGD) for 30 min and then placed in the normal culture condition. The ischemia-reperfusion produced a time-dependent increase in nitrite levels in the culture medium. Reverse transcriptional-polymerase chain reaction showed augmented levels of mRNA for both nNOS and iNOS when compared with control at 12 h and remained increase at 36 h after OGD (P < 0.05). The protein levels of both nitric oxide synthase isoforms increased significantly as determined by Western Blot. OGD also caused neurotoxicity in this model as revealed by the elevated lactate dehydrogenase (LDH) efflux into the incubation solution. The results suggest that organotypic hippocampus slice is a useful model in studying ischemia-reperfusion brain injury. NO and NOS may play a critical role in the ischemia-reperfusion brain damage in vitro.

Current studies show that postoperative adjuvant radiotherapy (PORT)may improve local control and overall survival for Ⅲ A-N2 NSCLC.With modern radiotherapy technology and techniques,the adverse effect of PORT is moderate and tolerated.Besides,modern PORT doesn′t decrease the survival.Inves-tigation concerning postoperative target volume for PORT is rare,so that definite agreement has not been reached.Available informations suggest that clinical target volume should include bronchial stump,involved lymph nodes,ipsilateral hilar nodes,subcarinal nodes and ipsilateral lower paratracheal nodes.

Objective To investigate clinicopathological features of scalp angiosarcoma, and to analyze the relationship of tumor stage and treatment with prognosis. Methods Clinical and follow-up data were collected from 16 patients with non-metastatic primary scalp angiosarcoma treated in the Department of Plastic and Reconstructive Surgery of Zhongda Hospital, Southeast University from September 2002 to June 2013. According to the seventh edition American Joint Committee on Cancer (AJCC)TNM staging system for soft tissue sarcomas (2010), staging of scalp angiosarcoma was performed for the 16 patients. Statistical analysis was carried out by the Kaplan-Meier method for survival rates and by the Log-rank test for survival curve. The Cox regression model was used for multivariate regression analysis. Results Of the 16 patients, 4 had stageⅠangiosarcoma, 4 stage Ⅱangiosarcoma, and 8 stage Ⅲ angiosarcoma. The tumor usually began as ecchymosis-like lesions on the head or face in early stage, and progressed into dark red infiltrative plaques, nodules and ulcers which easily ruptured and bled in later stage. Histopathological examination showed generalized vascular proliferation and infiltration with high histological morphological diversity. Cytologic atypia was commonly seen. The median time to recurrence was 15 months, and local recurrence occurred in 7 patients. The median time to metastasis was 20.5 months, and distant metastasis was observed in 8 cases, including 4 cases of pulmonary metastasis, 2 lymph node metastasis, 1 liver metastasis and 1 bone metastasis. The survival time was 33.0 ± 4.4 months (median, 32 months)in 4 patients with stage Ⅰangiosarcoma, 24.0 ± 7.9 months(median, 15 months)in 4 patients with stage Ⅱangiosarcoma, and 23.9 ± 3.9 months (median, 24 months)in 8 patients with stage Ⅲ angiosarcoma. Additionally, the survival time was 23.4 ± 5.2 months(median, 21 months), 24.4 ± 5.7 months(median, 24 months)and 35.8 ± 9.7 months(median, 26 months) in 5 patients receiving surgical treatment alone, 7 patients receiving surgical treatment and radiotherapy, and 4 patients receiving surgical treatment, radiotherapy and immunotherapy, respectively. Conclusions Surgical treatment combined with radiotherapy and immunotherapy may serve as the first-choice treatment for scalp angiosarcoma. Tumor size and treatment regimens are main factors influencing prognosis of scalp angiosarcoma.

ObjectiveTo explore environmental conditions under which bone marrow stromal cells could be induced into osteogenic phenotype.MethodsRat bone marrow stromal cells were isolated and proliferated in vitro, and the 3rd passage was divided into the group A (control group), group B (cells cultured in the medium containing dexamethasone, β-glycerol disodium phosphate salt hydrate, vitamin C and active form of vitamin D3), and group C (on the bases of group B, the cells were cultured additionally with fracture hematoma extract). On the post-induction day 5, 8, and 11, the morphological changes were observed and the osteogenic markers such as alkaline phosphotase (ALP), collagen type Ⅰ (Col Ⅰ) and osteocalcin (OCN) were assayed with immunohistochemical staining, the calcification was manifested with von Kossa staining.ResultsIn the group A, no evident osteogenic effects had been observed. In the group B, on 5th day post-induction, some bone marrow stromal cells underwent a morphological change, and mild expression of ALP and Col Ⅰ was observed but with no calcification effect. On 8th day post-induction, the ratio of morphologically changed cells increased, and the expression of ALP and Col Ⅰ increased still with no evident calcification. On 11th day post-induction, anti-OCN staining was positive and the calcium nodes were showed by von Kossa staining. The phenotype changes in the group C were similar to group B, but were more evident.ConclusionBone marrow stromal cells can be induced into osteogenic phenotype in vitro with small molecular inducers. Fracture hematoma extract can enhance this effect thus might be used as an addictive in osteogeneration.

Objective To investigate the effect of restraint stress on liver injury in mice induced by D-galactosamine and lipopolysaccharide (D+L).Methods Normal BALB/c (B/c) mice were randomly divided into normal control, stress control, D+L group, and D+L+stress group.The mice of normal control group were bred routinely.The stress group was giv-en stress regularly and quantitatively.Mice in the D+L group were injected intraperitoneally with mixed solution of D-galac-tosamine and lipopolysaccharide at final concentration of 30 mg/mL and 2μg/mL, respectively, once every two days.The D+L+stress group was given equal stress as stress group after injection of D-galactosamine and lipopolysaccharide mixed solution. Eight weeks later, blood samples were collected to test serum aminotransferase (ALT) and aspartate aminotransferase (AST), liver tissue samples from all animals were collected to evaluate the degree of liver fibrosis by HE and Masson staining.Results At the 8th week, the ALT and AST values in the D+L+stress group were significantly reduced( P＜0.01) and AST/ALT value was significantly increased(P＜0.01)compared with that in the D+L group.For HE and Masson staining, disordered structure of hepatic lobules, nodular hyperplasia, and necrosis of epithelial cells were present in animals of the D+L group.However, no obvious pathological changes were observewd in the D+L+stress group.For fibrosis scores, the fibrosis grade in the D+L+stress group was significantly decreased than that of the D+L group (P＜0.05).Conclusions Constraint stress presents pro-tective effect on D-galactosamine and lipopolysaccharide induced liver injury in mice.
