The etiology and pathogenesis of inflammatory bowel disease are up to now still not clear and definite. Establishing the ideal animal model to study its cause and pathogenesis of this disease is very important. The ideal animal model should have the same manifestation with human inflammatory bowel disease on clinical and pathologic feature etc. In this article, the method, the pathologic character istics and concerning pathogenesis, of a few common useful experiment animal models are discussed.

Objective To analyze the coincidence situation of the results of neonatal ABO blood group reciprocal stereotypy with crossmatching test of allotype blood and to investigating the limitations of cross-matching test in infant blood transfusion and effec-tive measures for ensuring the neonatal safe blood transfusion.Methods The micro-column gel test was adopted to identify the ABO blood group and conduct the crosshatching test of allotype blood in 1 095 cases of neonatal blood samples.Results Among the 1 095 samples,the detected rates of weak A and weak B antigen were 3.99% and 17.93% respectively,and the weak B antigen was predominant.The negative rates of anti-A and anti-B antibody were 53.72% and 60.70% respectively;in the cross-matching test with allotype blood,the main side without appearing agglutination accounted for 52.87% and weak agglutination accounted for 33.27%,and the secondary side appearing weak agglutination accounted for 9.49%.Conclusion The maturity of antibody and an-tigen and the coincidence rates of group typing and reciprocal stereotypy in the newborns are less than those in the adults;so blood transfusion according to the cross-matching test results has certain limitation;high attention should be paid to the accuracy of neo-natal ABO blood type,the individual blood transfusion strategy in the newborn should be determined in order to avoid hemolytic blood transfusion reaction caused by ABO allotype blood transfusion and ensure the blood transfusion safety in newborns.

The paper reported three young women who collapsed into sudden abnormal behavior and convulsions and fell into unconsciousness. After admission, they were found to suffer from ovarian teratomas with anti-NMDAR antibody positive in cerebrospinal fluid or serum. The patients were diagnosed as anti-NMDAR encephalitis associated with ovarian teratoma, and teratoma resection was performed.

AIM: To investigate DNA-binding activity of nuclear factor ka ppa B (NF-?B) and pyrrolidine dithiocarbamate (PDTC) anti-inflammation effect and mechanism in trinitrobenzene sulfonic acid (TNBS)-induced acute colitis in rats. METHODS: Acute colitis was induced by instilling TNBS/ ethanol into the lumen of the rat colon. Rats were randomized into PDTC-treat g roup (including group P10,P25,P50,P100), TNBS/ethanol group and normal control g roup. The rats in PDTC-treated group were injected intraperitoneally with PDTC at the dosages of 10, 25, 50, and 100 mg?kg -1 , respectively. Rats wer e killed at 4 h after enema. Colonic inflammation, the ratio of wet/dry weig ht and MPO, SOD, and MDA activity were detected. DNA-binding activity of NF-? B was assessed by EMSA. RESULTS: NF-?B activity in colon homog enate was increased markedly at acute colitis in rats. PDTC attenuates the devel opment of rat colonic inflammation but not by reducing the NF-?B activity. CONCLUSION: NF-?B is activated in rats with acute colitis, which may be a mechanism of self-protection. PDTC can attenuate the development of in flammation.

The present paper aims to investigate whether or not vasculogenic mimicry (VM) exists in laryngeal squamous cell carcinoma (LSCC), and to elucidate its relationship to microvessel density (MVD), galectin-3 (Gal-3) expression, and clinicopathological factors of patients with LSCC. VM, score of MVD and expression of Gal-3 protein were detected by immunohistochemistry and histochemistry in 83 specimens of LSCC tissue and 20 specimens of normal laryngeal tissue. The positive rate of VM in normal laryngeal tissues was 0%, and was 33.7% in LSCC tissues. There was a significant difference between the two groups (P<0. 01). VM or MVD was significantly related to differentiation, pTNM stages and lymph node metastasis of LSCC (P<0.05), but not to age, gender and tumor site (P>0. 05). And there was a positive correlation between every two of VM, score of MVD, and Gal-3 protein (P< 0. 05). The results suggest that expression of Gal-3 protein may be related to the initiation, angiogenesis and VM formation in LSCC; And VM, angiogenesis and Gal-3 protein may be involved in the development, invasion and metastasis of LSCC.

Objective To detect and analyze nuclear factor kappa B (NF-κB),Helicobacter pylori (HP),Helicobacter pylori cytotoxin associated protein A (CagA),platelet (PLT) and platelet associated IgG (PA IgG) in 224 patients with idiopathic thrombocytopenic purpur(ITP) from three urban hospitals of Shaoxing,in order to explore the role of NF-κB and CagA in the pathogenesis of ITP,then to improve the prognosis of ITP.Methods SABC method was used to detect the NF-κB,13C breath test for the determination of the Hp infection.CagA and PA-IgG were tested by enzyme linked immunosorbent assay.Automatic blood cell analyzer was used to measure PLT.According to the test results,the patients were divided into Hp+cagA+NF-κB+,Hp+cagA+NF-κB-,Hp+cagA-NF-κB+,Hp+cagA-NF-κB-,Hp-NF-κB+,Hp-NF-κB-PLT groups,and PA-IgG,PLT of the six groups were statistically analyzed.Results Of 224 cases with ITP,175 cases of HP positive,the positive rate was 78.13%.CagA+ 91 cases in 175 cases of Hp+,accounting for 52%,overall 43.63%.NF-kappa B+ 108 cases,the positive rate was 46.21%,78 cases were found in Hp+cagA+,accounting for 85.71% in cagA+.In 84 cases of Hp+cagA-,there were 21 cases NF-κB+,the positive rate was 25%.In 49 of HP-,9 cases with NF-kappa B+,accounting for 18.37%.PLT and PA-IgG were compared among the groups.The count of PLT of group Hp+,group Hp+cagA+ and group NF-κB+ was lower than group Hp-,group Hp+cagA- and group NF-κB-.However,the level of PA-IgG of group Hp+,group Hp+cagA+ and group NF-κB+ was higher than group Hp-,group Hp+cagA- and group NF-κB-,the difference was statistically significant(P<0.05).Conclusion CagA maybe directly or through the activation of NF-kappa B take part in the immune response of ITP,cause PA-IgG increased and thrombocytopenia.

By searching the registry information of systematic review regarding acupuncture included before March 31, 2014 in PROSPERO systematic review registry platform, information in the project plan such as care gories of diseases, interventions, research team and the completion status was analyzed to make a comprehensive understanding on registry status of acupuncture systematic review in this platform. As a result, a total of 52 project plans was finally included. The health problem concerned was mainly painrelated diseases, and the interventions were mostly simple acupuncture or combination of acupuncture and moxibustion. The registered plan participated with Chinese team appeared comparatively late, which was featured with fewer independent projects and concentrated research organization, so its scientific research advantage in acupuncture did not present. In conclusion, it is believed that the consciousness on systematic review registry in domestic researchers needs to be improved, and researchers might take good advantages of the PROSPERO platform in the future.
