Objective To study anaphylactoid reactions induced by traditional Chinese medicine injections (TCMI) of Qingkailing (QKL) and Xuesaitong (XST) with RBL-2H3 cells;To provide some reference for improving the screening system of TCMI induced anaphylactoid reactions.Methods The IC50 induced by QKL and XST injections was determined by MTT assay. RBL-2H3 cells were stimulated with TCMI at different concentrations or with C48/80 or culture medium. Thirty minutes later, the supernatant was collected to determine the release of histamine andβ-hexosaminidase. The cell degranulation rate and the ultrastructure changes were observed. The ICR mice were given single injection of TCMI containing Evans Blue through tail vein. The number of the animal with blue ear, the total number of blue ears and the quantity of Evans Blue of extravasation were determined 30 minutes later.Results The IC50 of both QKL injection and XST injection was 12.5μL/mL. These two injections promoted RBL-2H3 cells to release histamine andβ-hexosaminidase at higher concentrations (P<0.05,P<0.01) in a dose dependent manner. Cell morphology showed a decrease of villous on the cell surface and an increase of the internal vacuolated structure. Both injections caused the blue ears of all animal with a rate of 100%. The quantity of Evans Blue of the extravasation was significantly increased (P<0.01). The results in vitro study were in close agreement with that in vivo.Conclusion Both QKL injection and XST injection may potentially cause anaphylactoid reactions. The RBL-2H3 cell model may be valuable to evaluate the anaphylactoid reactions induced by TCMI.

Objective To observe the iffectiveness of comprehensive rehabilitationinterventions on stroke patients with unilateral spatial neglect (USN). Methods A total of 245 cases if strijd were examined to diagnose USN. Of the 245 patients,86 cases were diagnosed as being with USN, and divided into a control group(n=43 cases) and a treatment group (n=43 cases) randomly. The control group was treated with Bobath and Rood techniques in addition to routine clinical medical interventions, while the treatment group was treated with a comprehensive rehabilitation protocol for USN in addition to the same interventions for the control group. Both groups were assessed with regard to motor, balance function, walking performance, and USN severity as well as the activities of daily living (ADL) performance. Results After 8 weeks of treatment,both groups improved, but there showed a significantly statistical difference between the 2 groups in terms of Fugl-Meyer motor function scores (P<0.01), balance function scores (P<0.01) Holden walding function classifications (P<0.01), Barthel index(P<0.001) and USN severity scores(P<0.01). Conclusion Comprehensive USN rehabilitation intervention could improve motor, balance, walking functions and ADL performance and alleviate the USN severity in stroke patients with USN.

Objective To evaluate the efficacy of preoperative regional intra-arterial chemotherapy (RIAC) in the treatment of resectable pancreatic head carcinoma. Methods The clinical data of 50 patients with resectable pancreatic head carcinoma who had been admitted to the Research Institute of Pancreatic Diseases of Fudan University from December 2006 to July 2007 were retrospectively analyzed. Patients were randomly divided into2 groups (n =25 in each group): patients in group A were treated with preoperative RIAC followed by regional pancreaticoduodenectomy, and patients in group B were treated with surgical procedure routinely. The lymphatic metastases in the 50 specimens of pancreatic head carcinoma were detected by histological examination with hematoxylin and eosin (HE) staining, and lymphatic micrometastases were detected by immunohistochemical method with staining of cytokeratin AE1/AE3 in 10 specimens with negative HE staining of the lymph nodes in each group. Results There was no significant difference in the incidence of complications, the length of hospital stay and the 1-, 2-year survival rates between the 2 groups (χ2 = 0.12, 2.88, P > 0.05). The incidence of positive lymph node metastasis in group A was 7.1% (52/734), which was significantly higher than 22.1% (118/532) in group B (χ2 = 60.01, P < 0.05). The incidence of lymphatic micrometastasis was 9.4% (30/319) in group A, and 9.1% (23/252) in group B, with no statistical difference between the 2 groups (χ2= 0.01, P > 0.05). Conclusions Preoperative RIAC is helpful in improving the prognosis of patients with resectable pancreatic head carcinoma by reducing the incidence of lymphatic metastasis and decreasing tumor stage.

Objective To investigate the clinical characteristics, diagnosis, treatment and prognosis of pancreatic gastrointestinal stromal tumor (GIST). Methods We reported a case and reviewed the medical literature on pancreatic malignant GIST. We searched the Pubmed and main domestic database. The clinical data of the reported cases were studied, and their predictive factors for postoperative recurrence and metastasis were analyzed. Results Between January 1980 and July 2010, 16 cases of pancreatic GIST were reported. There were 7 males and 9 females, with a median age pf 56.5 (31-72)years. The clinical symptoms were nonspecific. The main presentation was upper abdominal pain or discomfort. A preoperative diagnosis was suspected on radiological examination. The tumor mainly appeared as a well-defined solid-cystic mass. Irregular enhancement appeared in the circumferential and solid portion of the tumor on enhanced CT scan sequences. The pancreatic and biliary ducts were rarely dilated. Endoscopic ultrasound guided fine needle aspiration cytology (EUS-FNA) was helpful in preoperative diagnosis. Of the 15 surgical patients, 14 underwent complete resection, while the remaining received cyst-jejunostomy. A correct diagnosis was made on histopathology and immunohisto-chemistry. On a mean follow up of 21 months (range, 1-60) in 14 patients, all patients were alive.Recurrence or metastasis occurred in 4 patients with tumors of high malignant potential. On univariate analysis, the only significant predictor for adverse outcome was mitoses≥10/50 HPF. Conclusions Pancreatic GIST is a rare tumor of relatively low malignant potential. It has a better prognosis than ductal adenocarcinoma. It is important to arrive at a correct diagnosis and treat the tumor with radical resection. Aggressive surgical resection is potentially curative. Imatinib is recommended in the treatment of patients with tumors with high malignant potential.

AIM: To investigate the inhibitory effect s of a synthetic CRE-transcription factor decoy oligodeoxynucleotide (CRE-decoy ODN) on the upregulation of the expression of cholecystokinin (CCK) and fosB mRN A induced by chronic morphine administration in SK-N-SH cells. METHODS: The CRE cis-element, TGACGTCA, was palindromic, a sy nthetic single-stranded phosphorothioate oligodeoxynucleotide composed of the CR E sequence self-hybridizes to form a duplex/hairpin. The CRE-palindromic decoy a nd control oligodeoxynucleotides were added to the medium (1 h before exposure t o morphine) at 150 nmol/L in the presence of cationic lipid DOTAP. After the cel ls were treated with 100 ?mol/L morphine for 48 h, 10 ?mol/L naloxone was use d for 15 min. The effects of CRE-decoy ODN on the DNA-binding activity of CREB, the expression of CCK and fosB mRNA were detected by electrophoresis mobi lity shift assay (EMSA) and RT-PCR, respectively. The stability of cell-incorpo rated [ 32P]-labeled CRE-decoy ODN was extracted with phenol:chloroform a nd then subjected to 20% nondenaturing polyacrylamide gel electrophoresis and au toradiography. RESULTS: Chronic morphine administration and acute naloxone-prec ipitated withdrawal significantly activated the DNA-binding activity of CREB and the expression of CCK and fosB mRNA in SK-N-SH cells. The CRE-decoy ODN pen etrated into the cells, specifically downregulated these indexes. CONCLUSIONS: CRE-decoy ODN can significantly downregulates the e xpre ssion of CCK and fosB mRNA through specifically suppressing the DNA-binding activity of CREB activated by chronic morphine administration in SK-N-SH cells.

OBJECTIVEThe aim of the present study is to explore the effects of exhaustive exercise-induced oxidative stress on the antioxidant capacity and diformability of rat red blood cells.
METHODSRats were divided into three group (n = 10): sedentary control (C), exhaustive running exercise (ERE) and moderate running exercise (MRE) groups. Animals in the ERE group started treadmill running at a speed of 20 m/min speed with a 5% gradient, and reached a speed of 25 m/min with gradient 15% in 20 min. Running was continued until exhaustion. MRE group rats running at a speed of 20 m/min with a 5% gradient for 40 min. The levels of free thiol in erythrocyte membrane protein, lipidperoxidation levels and membrane protein components were analyzed. The red blood cell deformability of different groups was also observed.
RESULTSThe results showed that red blood cells were damaged by severe oxidative stress and the anti-oxidative capacity decreased significantly under exhaustive exercise conditions. Besides, lipid peroxidation and protein sulfhydryl cross-link based clustering of membrane were found after exhaustive exercise, and polymers high molecular weight (HMW) was formed. The elongation index (EI) was found to decline significantly in the ERE group compared with the C and MRE groups under shear stress (control group, 0.41 +/- 0.01 at 3 Pa and 0.571 +/- 0.008 at 30 Pa; ERE group, 0.314 +/- 0.013 at 3 Pa and 0.534 +/- 0.009 at 30 Pa; P < 0.05 and P < 0.01, respectively).
CONCLUSIONThese exercise-induced oxidative injure result in a significant decrease in deformability of rat erythrocytes, which in turn leads to dysfunction in the microcirculatory.
