OBJECTIVETo observe the clinical efficacy of combination of traditional Chinese medicine and western medicine in the treatment of patient bitten by agkistrodon halys pallas, and the changes in peripheral blood inflammatory factors (hs-PCR, IL-6, TNF-alpha).

METHODNinty-eight patients were divided into three groups according to their hospitalization dates: the western medicine group, in which 32 patients were treated with antivenom serum (6 000 U) for five days, once every day; the traditional Chinese medicine group, in which 32 patients were treated with anti pit viper No. 2 concentrated decoction (300 mL), twice to three times every day, for five days; and the combined traditional Chinese medicine and western medicine group, in which 35 patients were treated with the combination of Chinese and Western medicine treatment described above. Then blood samples of all of patients were obtained, and serum factors (hs-PCR, IL-6, TNF-alpha) in peripheral blood were measured by Elisa assay. Another 30 health volunteers were chosen as the normal control group.

RESULTThe serum inflammatory factors were significantly higher in all patients of the three groups than that in healthy control before treatment (P < 0.01), and decreased significantly after treatment. In particular, the more remarkable reduction was found in the combined traditional Chinese medicine and western medicine group compared with the western medicine group and the traditional medicine group (P < 0.01). Symptom elimination in the three groups was superior to the western medicine group and the traditional medicine group at the first day and the third day of treatment (P < 0.05, P < 0.01). Total clinical effective rate was 100% in the combined traditional Chinese medicine and western medicine group, 84. 37% in the traditional medicine group and 65.62% in the western medicine group, the clinical effective rate of the combined traditional Chinese medicine and western medicine group was notably superior to that of the western medicine group and the traditional medicine group (P < 0.01).

CONCLUSIONThe serum inflammatory factors increased significantly in patients bitten by agkistrodon halys pallas. Treatment with the combined traditional Chinese medicine and western medicine can significantly decrease the serum inflammatory factors, and increase clinical effect, with more obvious clinical efficacy compared with the western medicine group and the traditional medicine group.

OBJECTIVETo explore the possibilities of bone marrow stromal cells (MSCs) to adopt Schwann cell phenotype in vitro and in vivo in SD rats.

METHODSMSCs were obtained from tibia and femur bone marrow and cultured in culture flasks. Beta-mercaptoethanol followed by retinoic acid, forskolin, basic-FGF, PDGF and heregulin were added to induce differentiation of MSCs'. Schwann cell markers, p75, S-100 and GFAP were used to discriminate induced properties of MSCs' by immunofluorescent staining. PKH-67-labelled MSCs were transplanted into the mechanically injured rat sciatic nerve, and laser confocal microscopy was performed to localize the PKH67 labelled MSCs in the injured sciatic nerve two weeks after the operation. Fluorescence PKH67 attenuation rule was evaluated by flow cytometry in vitro.

RESULTSMSCs changed morphologically into cells resembling primary cultured Schwann cells after their induction in vitro. In vivo, a large number of MSCs were cumulated within the layer of epineurium around the injured nerve and expressed Schwann cell markers, p75, S-100, and GFAP.

CONCLUSIONMSCs are able to support nerve fiber regeneration and re-myelination by taking on Schwann cell function, and can be potentially used as possible substitutable cells for artificial nerve conduits to promote nerve regeneration.

OBJECTIVETo investigate the expression and relationship of p27(kip1) and its nuclear export factor Jab1 during proliferation process of lymphoma cell.

METHODSJurkat and Raji cells were treated with serum starvation and then serum release. The protein and mRNA expression of p27(kip1), Jab1 in the cells were detected by Western blot and RT-PCR respectively. LMB were used for stimulating Jurkat cells during their proliferation process, and then the expression changes of p27(kip1) and Jab1 were detected. An eukaryotic expression plasmid(pcDNA3. 1-myc) containing Jab1 was constructed. Jurkat cell were transfected in vitro with or without pcDNA3. 1-myc-Jab1. Double immunolabelling was used to identify the localization of p27(kip1). Immunoprecipitation was used to detect the combination of p27(kip1) and Jab1.

RESULTSThe growth of Jurkat and Raji cells were blocked by serum starvation. The total protein amount of p27(kip1) increased while that of Jab1 decreased. The reverse changes were happened after serum release, but the mRNA expression of p27(kip1) has no significant change. LMB could inhibit the cell proliferation caused by serum release. The expression of p27(kip1) was up-regulated and Jab1 down-regulated when Jurkat cells were treated with LMB. After pcDNA3. 1-myc-Jab1 infected Jurkat cells for 48 h, the distribution of p27(kip1) was translocated from nucleus into cytoplasma. p27(kip1) and Jab1 could form compound in Jurkat and Raji cells detected by Immunoprecipitation.

CONCLUSIONJab1 may influence the location and expression of p27(kip1) through integrating with p27(kip1), and then participates in regulating the growth of NHL cell through interfering with the function of p27(kip1).

OBJECTIVETo evaluate the effect of etodimate infusion on serum cortisol in patients undergoing radical resection of lung cancer operations during the perioperative period.

METHODSForty ASA I-II patients undergoing radical resection of lung cancer were randomly divided into etomidate group (Group E) and propofol group (Group P) (n=20). The serum cortisol was measured at 8:00 am (T(0)) before anesthesia, 4:00 pm (T(1)) on the day of operation and 24 h after the operation (T(2)) by radioimmunoassay.

RESULTSCompared with that at T0, the serum level of cortisol significantly increased at 24 h after the operation in both groups (P<0.01); serum cortisol decreased lightly at T1, which was not statistically significant (P>0.05), and remained higher than the normal level. At each of the time points, serum cortisol levels were comparable between the two groups (P>0.05).

CONCLUSIONEtomidate infusion can not inhibit the synthesis of cortisol in patients undergoing radical resection of lung cancer.

OBJECTIVETo investigate the expression and relationship of p27(kip1) and its related molecules Jab1 and CRM1 during proliferation of lymphoma cells U937.

METHODSU937 cells were treated with serum starvation and release, and the effects of these treatments on the cell growth was tested with cell number counting. The expression and localization of p27(kip1), Jab1 and CRM1 in U937 cells were detected by Western blot, double immunolabelling and laser scanning confocal microscopy.

RESULTSThe growth of U937 cells was blocked by serum starvation. The total protein of p27(kip1) was increased while Ser10-phosphorylated p27(kip1) -related molecules Jab1 and CRM1 were decreased. Meanwhile, the location of p27(kip1) was changed from cytoplasm into nuclei. After serum release, the location of p27(kip1) expression reappeared in the cytoplasm again.

CONCLUSIONDuring the proliferation process of lymphoma U937 cells, Jab1 and CRM1 may influence the location and expression of p27kip1, and may participate in regulation of growth of NHL cells.

BACKGROUNDTo study the relationship of Epstein-Barr virus (EBV) and T cell lymphoma.

METHODSSixty cases of T cell lymphomas were examined for the presence of EBV using in situ hybridization for EBV encoded RNA (EBERs).

RESULTSEBERs were detected in tumor cells in 37(69.8%) of 53 cases with peripheral T cell lymphoma, but in none of seven cases of precursor T lymphoblastic lymphoma. The total detected EBERs were 37(61.6%) in 60 cases of T cell lymphomas. By Revised European-American Lymphoma(REAL) classification, EBERs were detected in 2/2 angioimmuno-blastic T cell lymphoma,17/18 angiocentric lymphoma, 4/6 anaplastic large cell lymphoma and 14/27 peripheral T cell lymphoma, unspecified (51.9%). The frequency of EBERs among the extranodal peripheral T cell lymphoma was higher than the nodal (P less than 0.01) there was no significant correlation with the sex, age and clinical stage.

CONCLUSIONSThis study indicated that high incidence of EBV was observed in peripheral T cell lymphoma, with predilection for angiocentric lymphoma and extranodal presentation.

OBJECTIVETo study the changes of serum albumin contents after operation and investigate whether post-operational serum albumin contents are correlated with the disease severity in children with acute intussusception.

METHODSSerum albumin contents were measured using the automatic biochemistry analyzer in 32 children with mild acute intussusception and 21 children with severe acute intussusception 1 day after surgical operation. After 5 days combined treatment, serum albumin contents were re-examined. Thirty healthy children severed as the control group. The correlation between post-operational serum albumin contents and critical illness scores was evaluated.

RESULTSSerum albumin contents in the mild (34.2+/-6.5 g/L; P<0.05) and the severe intussusception groups (25.8+/-7.5 g/L; P<0.01) 1 day after operation were significantly lower than those in the control group (37.1+/-4.1 g/L). There were significant differences in serum albumin contents between the mild and the severe intussusception groups (P<0.05). Five days after operation, serum albumin contents in the mild intussusception group significantly increased (37.1+/-11.4 g/L; P<0.05), while serum albumin contents in the severe intussusception group did not differ from those 1 day after operation. There was a positive correlation between serum albumin contents on the 1st day after operation and the critical illness scores (r=0.879, P<0.01).

CONCLUSIONSSerum albumin contents decreased on the 1st day after operation and were correlated with the disease severity in children with acute intussusception. Hypoalbuminemia lasted for a longer period in severe cases. The post-operational measurement of serum albumin contents may be useful in the evaluation of the severity for children with acute intussusception.

PURPOSE: To assess the clinical manifestations and multidetector-row computed tomography (MDCT) findings of afferent loop syndrome (ALS) and to determine the role of MDCT on treatment decisions. MATERIALS AND METHODS: From January 2004 to December 2008, 1,100 patients had undergone gastroenterostomy reconstruction in our institution. Of these, 22 (2%) patients were diagnosed as ALS after surgery that included Roux-en-Y gastroenterotomy (n=9), Billroth-II gastrojejunostomy (n=7), and Whipple's operation (n=6). Clinical manifestations and MDCT features of these patients were recorded and statistically analyzed. The presumed etiologies of obstruction shown on the MDCT were correlated with clinical information and confirmed by surgery or endoscopic biopsy. RESULTS: The most common clinical symptom was acute abdominal pain, presenting in 18 patients (82%). We found that a fluid-filled C-shaped afferent loop in combination with valvulae conniventes projecting into the lumen was the most common MDCT features of ALS. Malignant causes of ALS, such as local recurrence and carcinomatosis, are the most common etiologies of obstruction. These etiologies and associated complications can be predicted 100% by MDCT. CONCLUSION: Our results suggest that MDCT is a reliable modality for assessing the etiologies of ALS and guiding treatment decisions.
