Objective To observe the results of melatonin combined with alprostadil in the treatment of patients with acute pancreatitis.Methods Seventy patients with acute pancreatitis were included in the study,14 patients died after conventional treatment were set to group Ⅰ ,28 patients cured after conventional treatment were set to group Ⅱ and 28 cases cured after melatonin combined with alprostadil and conventional treatment were set to group Ⅲ.White blood cell count,blood gas analysis,serum amylase,endotoxin and malondialdehyde (MDA) content was detected at 6 h,48 h and 4 d.Results White blood cell count,serum amylase,endotoxin,MDA content at 6 h,48 h and 4 d in group Ⅰ were higher than those in group Ⅱ ,Ⅲ (P＜0.05).Endotoxin levels reached a maximum in the 4 d [(273.5 ± 20.4) pg/L],and MDA content reached a maximum in the 4 d [(5.12 ± 0.87) μmol/L].White blood cell count,partial pressure of carbon dioxide in artery (PaCO2),serum amylase,endotoxin and MDA content at 48 h,4 d in group Ⅲ were lower than those in group Ⅰ,Ⅱ (P <0.05).Conclusions Melatonin combined with alprostadil not only shows antioxidant,anti-inflammatory,anti-apoptotic effect but also improves the pancreas,lung,small intestine microcirculation,protects the cell membrane and the lysosomal membrane,and prevents effectively the pancreatic digestive enzymes release; also it inhibits intestinal bacterial translocation,reduces the generation of gut-derived endotoxin and pro-inflammatory cytokine release.It can reduce effectively the systemic inflammatory response in acute pancreatitis.

Recent evidence suggests that, in spite of the redundancy of angiogenic factors involved in pathological angiogenesis , strategies aimed at inhibiting specific endothelial cell angiogenic factors at their release or receptor level may form the basis for effective and safe treatment of angiogenic mediated disease processes. Physiologic angiogenesis is fundamental to reproduction, development and repair. Pathological angiogenesis sustains the progression of many neoplastic and proinflammatory diseases. And endothelial cell is an important target especially for the angiogenesis. The target represents a novel strategy for the treatment of the human disorders where pathological angiogenesis is involved.

Objective To investigate the mRNA,protein expression and tyrosine phosphorylation of insulin receptor substrate.1(IRS-1)in endometrial carcinoma.Methods Sixty-three endometrial carcinoma(EC)patients,21 endometrial atypical hyperplasia(AHE)patients and 22 normal control(NE) entered this smdy.Their clinical information were colleeted Fasting serum C-peptide concentration was measured.Expression of IRS-1 in endometrium was examined by RT-PCR and western blol Immunoprecipitation was used to measure the tyrosine phosphorylation of IRS-1.Results C-peptide 0.007].There were no significant differences in IRS-l mRNA and protein expression among the three grouDs.Tyrosine phosphorylation of IRS-1 in EC group[(62±36)%]was higher than that in AHE and NE groups[(53 4-34)%and(35 4-33)%;P=0.048,0.002].IRS-1 activation in AHE group was also higher than nornlal control(P=0.045).IRs-1 activation in endometrioid carcinoma[(69 4-33)%]was higher than that in other histological types[(34±31)%;t=2.300,P=0.025].IRs-l tyrosine phosphorylation was significantly higher in patients with advanced stage,high grade,deep myometrial invasion and pelvic lymph node metastasis.IRS-l activation in endometrium was positively correlated with fasting sertlm C-peptide concentration(r=0.491,P=0.001).Conclusions There is excessive activation of IRS-1 in endometrial carcinoma and atypical hyperplasia.Activation of IRS-I in endometrial carcinoma is related with poor clinical-pathologic fleatures and may be a prognostic predictor for this tumor.Over-activationof IRS-1 may be an intermediate event linking the hyperinsulinemia and endometrial carcinoma.

Objective To evaluate the imaging performance and characteristics of peripheral primitive neuroectodermal tumors (pPNET), in order to raise awareness of the disease and the diagnostic accuracy. Methods Thirteen patients with pPNET who confirmed by puncture or pathology were enrolled in this study. The CT and MRI features were retrospectively analyzed. Four patients received simple routine CT examination, and 9 patients had MRI examination based on X-ray, CT examination. Results The part of body involved was more widely.Two patients occurred in the sinuses, 1 patient in the chest wall, 1 patient in the lung, and 3 patients in the abdominal and pelvic(1 patient involved the pelvic floor through the pelvic wall lesions to basins), 1 patient in the spine, and 5 patients located in the extremities. The characteristics of pPNET by CT and MRI in soft tissue of 8 patients showed single large soft tissue mass, and the biggest was 11.2 cm × 10.6 cm. In bonds and joints of 5 patients, CT and MRI showed wide range of soft tissue mass, mixed internal signal/density with obviously uneven enhancement, significant bone destruction and dissolvable osseous changes, and no obvious tumor bone and calcification. Conclusions Each site has its relative imaging characteristics of pPNET. CT and MRI can show lesions involving the scope, internal structure, with or without adjacent tissue invasion and metastasis, and provide guidance for clinical treatment and selecting treatment regimen. But in the end, it depends on the diagnosis of pathological and immunohistochemical examination.

Objective This study was designed to investigate the expression changes of osteopro-tegerin (OPG), tartrate-resistant acid phosphatase (TRAP) and vascular endothelial growth factor (VEGF) mRNA in collagen induced arthritis(CIA) rats. Methods After CIA was induced in Sprague-Dawley rats, the experimental animals were treated with PBS or rAAV-EGFP or rAAV-hOPG (100 μl/day) intra-articular injection for 10 days. Messenger RNAs (mRNAs) were obtained from CIA synovium 40days after first immun-ization. Reverse transcriptase-polymerase chain reactions (RT-PCR) were carried out to detect the mRNA encoding OPG, TRAP, VEGF and β-actin, which acted as inner control. The genes detected clearly by RT-PCR were quantified using real-time PCR. Results The expression of all genes was confirmed by specific single bands in RT-PCR. Real-time PCR showed that the expression levels of TRAP and VEGF were increased, whereas those of OPG mRNA were decreased in CIA group compared with normal controls. The intra-articular gene transduction markedly increased the gene copies of OPG by 128.21% (P<0.01). The expression change of OPG in synovium also caused the decrease of the expression levels of TRAP and VEGF by 58.79% (P<0.01)and 17.85% (P>0.05) respectively, however, the expression change of VEGF was not statistically significant. Conclusion OPG gene mediated by rAAV can be successfully tranfered to knee joint synovium in vivo. The results of this study suggest that gene transfer using rAAV-OPG may be a feasible and effective therapeutic approach to treat or prevent joint destruction in inflammatory arthritis.

Objective To study the levels of Th1 and Th2 type cytokines in 3-nitrobenzene sulfonate(TNBS) and oxazolone(OXZ) colitis without or with Trichinella spiralis( T. spiralis) infection. Methods Female BALB/c mice were randomly divided into 4 groups: 50% Ethanol, T. spiralis only, TNBS or OXZ,T. spiralis +TNBS or OXZ(at least 6 in each group when mice were killed). The levels of IFN-γ, IL-12,IL-4, IL-10 in colon in mice with colitis induced by TNBS or OXZ without or with T. spiralis infection 3 d and 7 d post-induction were assessed using ELISA method. Results Colonic protein levels of IFN-γand IL-12 were significantly increased 3 d and 7 d after intra-colonic injection of TNBS( P ＜0.05 ). Concurrent infection with T. spiralis prevented this rise in IFN-γand IL-12 secretion and tended to induce a rise in colonic IL-4 and IL-10 content(P ＜0. 05). The levels of IFN-γ, IL-4 and IL-10 protein in colitic mice colon with prior nematode infection on days 3 and 7 post-induction of colitis were significantly higher than that seen in colitic mice without prior nematode infection ( P ＜ 0.05 ). Conclusion T. spiralis infection significantly attenuates TNBS-induced colitis in mice. The local immunologic mechanism is that T. spiralis can down-regulate strongly Th1-type immune response of colitis and up-regulate Th2 response, Tr1-cytokines. According to the change of Th1/Th2 cytokines, prior T. spiralis infection doesn't reduce the severity of OXZ-induced colitis, but without aggravating colitis. The exactly immunologic mechanism deserve to be explored deeply.

Objective Using an in vivo adeno-associated virus(AAV)-mediated gene transfer technique,this study was designed to evaluate the protective effects of human osteoprotegerin(OPG)transgene against joint destruction in collagen induced arthritis(CIA)model.MethodsAfter CIA was established in the Sprague-Dawley rats,the experimental animals were treated with PBS or rAAV-EGFP or rAAV-hOPG (100μl/d)intra-articular injection 25 days after arthritis induction for 10 days.Paraffin-embedded joints were then analyzed histologically.The joint destruction was evaluated by Larsen Score.The protein expression of OPG,IL-1,MMP-3 was identified by enzyme-linked immunosorbent assay(ELISA).Results Suecessful trans-gene expression was confirmed by the detection of OPG by ELISA and positive fluorescence of the frozen joint section. Image analysis revealed that the expression of OPG significantly protected against joint destruction by 30% compared with the CIA group. Conclusion OPG gene transfer mediated by rAAV effectively protects against bone destruction induced by CIA model. Those data suggest that gene transferring using rAAV-OPG may be a feasible and effective therapeutic approach to treat or prevent joint destruction in inflammatory arthritis.

Objective To observe the effect of Tomatis converted auditory training on the executive functioning of breast cancer patients undergoing chemotherapy.Methods Eighty breast cancer patients with the executive dysfunction who were undergoing chemotherapy were divided into a control group and an experimental group,each of 40.The experimental group was given Tomatis high and low frequency auditory training,while the control group was given ordinary music training.The patients in both groups were treated in 4 stages,each of 5 consecutive days with intervals of 21 days.The Chinese Version of the Behavioral Assessment of Dysexecutive Syndrome (BADS) was used to evaluate both groups before and after the intervention,including rule transformation ability,problem solving ability,planning ability,supervising ability and organizing ability.Results After the intervention,the experimental group had a significantly higher average score than before the intervention in the rule-switching card test,the action planning test,the key-finding test,and the modified six-element test.Their average BADS score was also significantly improved.The control group showed a significantly better average score only in the key-finding test and in its average BADS total score.After the intervention,the experimental group had a significantly higher average score than the control group in the rule-switching card test and the action planning and six-element tests.Its average BADS rating was also significantly better.Conclusion Tomatis high and low frequency auditory training can improve the executive function of patients undergoing chemotherapy for breast cancer.Its effect is better than that of ordinary music training.
