The PBSC with red blood cells(8～11ml) without elimination before infusion were harvested by CS 3000 Plus.The leve1 of blood group antigens and antibodies and bone marrow cells morphology were examined at different intervals after transplantation. 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.

OBJECTIVE:To observe clinical effects and safety of small dose of octreotide for preventing hyperamylasemia and acute pancreatitis after endoscopic retrograde cholangiopancreatography (ERCP).METHODS:One hundred and twenty ERCP pa tients were selected from our hospital during Oct.2014-Jan.2015 and then divided in to observation group and control group in accordance with random number table,with 60 cases in each group.Both groups were given Diazepam tablet 10 mg+Meperidine hydrochloride tablet 100 mg+Phenobarbital scopolamine tablet 2 tablets 0.5 h before surgery for sedation and analgesia,and routine acid suppression and anti-infective therapy.Observation group was additionally given Octreotide acetate injection 0.1 mg hypodermically and then given Octreotide acetate injection 0.1 mg immediately after surgery,8 h after surgery.The levels of serum amylase and blood glucose were observed in 2 groups,and the occurrence of postoperative complication and ADR were recorded.RESULTS:Before operation,there was no statistical significance in the levels of serum amylase and blood glucose between 2 groups (P＞ 0.05).After operation,the level of serum amylase in control group was significantly higher than in observation group,with statistical significance (P＜0.05).There was no statistical significance in blood glucose level between 2 groups after operation (P＞0.05).The incidence of hyperamylasemia and ADR in observation group was significantly lower than in control group,with statistical significance (P＜0.05),and there was no statistical significance in the incidence of acute pancreatitis between 2 groups after operation (P＞0.05).CONCLUSIONS:Small dose of octreotide can effectively reduce the level of serum amylase and the incidence of hyperamylasemia after ERCP with good safety.

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 The aim of this study was to establish a mouse model of chronic hepatic injury induced by low dose carbon tetrachloride ( CCl4 ) .Methods Twenty SPF male B/C mice ( body weight 18-20 g) were randomly di-vided into three groups including the CCl 4-treated group , oil-treated group and non-treated control group ( n=5/group ) . Mice in the CCl4-treated group were intraperitoneally injected with 0.5% CCl4 prepared in oil.Mice in the oil group re-ceived intraperitoneal injection of oil .Mice in the non-treated control group were left untreated .After 6 weeks, the serum levels of alanine aminotransferase (ALT) and aspartate aminotransferase (AST) were measured, as well structure, cellular morphology and degree of fibrosis of the hepatic tissues were examined by histology with HE and Masson staining .Results After low dose CCL4 treatment, the serum ALT and AST were significantly increased (P =0.00).Histology with HE stai-ning showed extensive vacuolar degeneration of hepatic epithelial cells and large number of necrotic foci .Histology with Masson staining revealed fibrous hyperplasia mainly located around hepatic lobules .Quantitative analysis of the fibrosis showed that the degree of fibrosis and the integrated optical density of fibrosis were significantly increased after CCl 4 induc-tion( P=0.00) .Conclusion Low dose carbon tetrachloride can induce hepatic injury in B /C mouse models presenting pathological changes of hepatic injury and fibrosis .
