Objective To investigate the correlation between expression of carcinoembryonic antigen (CEA) mRNA in preoperative peritoneal lavage fluid and prognosis of operation in patients with gastric cancer.Methods The expression levels of CEA mRNA in preoperative peritoneal lavage fluid of 68 patients with gastric cancer and 30 patients with gastric benign tumor were measured by reverse transcription polymerase chain reaction.The correlation between the expression level of CEA mRNA in preoperative peritoneal lavage fluid and clinicopathological features,prognosis of postoperative were analyzed.Results The expression level of CEA mRNA in preoperative peritoneal lavage fluid of patients with gastric cancre was 1.74 ± 0.25 and with gastric benign tumor was 0.19 ± 0.04,and there was statistical difference (P ＜ 0.05).The expression level of CEA mRNA in preoperative peritoneal lavage fluid had a correlation with the tumor infiltration depth,tumor differentiation,lymph node metastasis,distant metastasis and TNM stage (P ＜ 0.05).There was statistical difference in the recurrent / metastasis rate and survival rate 1 year after operation between low (34 cases) and higher (34 cases) expression level of CEA mRNA in preoperative peritoneal lavage fluid of gastric cancer patients:47.06％ (16/34) vs.82.35％ (28/34) and 79.41％ (27/34) vs.55.88％ (19/34),P ＜ 0.05.Conclusion The expression of CEA mRNA in preoperative peritoneal lavage fluid has close correlation with the clinicopathologic features,and the high expression of CEA mRNA indicats poor prognosis,indicating that CEA mRNA in preoperative peritoneal lavage fluid could be used as a prognostic marker in patients with gastric cancer.

Currently, multimedia teaching plays a more and more important role in colleges.However, the negative effects of multimedia teaching have gradually revealed because of the neglection of its limitations. In this article, strategies were proposed from three different aspects against disadvantages of multimedia teaching in colleges in order to improve its role more effectively.

Sijunzi Decoction (SJZD) is a classical prescription for curing spleen deficiency in traditional Chinese medicine, consisting of Ginseng Radix et Rhizoma, Atractylodes Macrocephalae Rhizoma, Poria, and Glycyrrhizae Radix et Rhizoma Praeparate cum Melle. Modern pharmacological experiments have proved that sponin, flavonoid, and polysaccharide are the most active ingredients in SJZD. SJZD has been used to regulate gastrointestinal function and enhance immunity ability. Effects on tumor cell apoptosis and anti-aging have also been reported. But few report on SJZD polysaccharide and its therapeutic basis research was found. This review is to give a comprehensive summary of information regarding the chemical constituents and pharmacological effects of SJZD to help us take the action for reasonable clinical utilization and further researches of SJZD.

Literature review of the world on hospital brands, data collection in summary and comparison, and specialist consultancy were used to set the appraisal indicators, while the stratum analysis was used to calculate the weight coefficients of individual indicators, for building the appraisal indicators system for hospital brand effect. In addition, the indicators system and appraisal model were called into play to explore the use of hospital brands, offering scientific references for hospital management.

Objective To investigate the effect of Abro1 on acute respiratory distress syndrome(ARDS)/acute lung injury(ALI)in mice.Methods Abro1 knock-out(KO)mice and wild type(WT)mice were both randomly divided into two groups for intratracheal instillation of lipopolysaccharide(LPS)or normal saline.At 6 or 24 hours after treatment, the pathological changes in lung tissue were observed by HE staining.At 6 hours after treatment,inflammatory immune cells and cytokines production(IL-6)in the bronchoalveolar lavage fluid were examined.Myeloperoxidase(MPO)and the mRNA level of IL-6 in the lung tissue were compared.Results At 24 hours after treatment, compared with WT mice treated with LPS,Abro1 KO mice showed a significantly lower lung injury score.At 6 hours after treatment,Abro1 depletion resulted in reduced levels of inflammatory immune cell infiltration and cytokines production(IL-6)in the bronchoalveolar lavage fluid(P<0.05).In addition,the MPO content and the mRNA level of IL-6 in the lung tissue were much lower than those in WT mice treated with LPS for 6 hours(P<0.05).Conclusion Abro1 deficiency can attenuate LPS-induced ARDS/ALI.

Objective To study the methods and value of emergency interventional therapy in digestive tract bleeding.Methods 61 cases with digestive tract bleeding accepted emergency angiography.According to find out positions and causes of bleeding during angiography,these patients accepted arterial embolization and /or perfusion of vasoconstrictor substance.Results In 29 cases accepted arterial embolization and 32 cases accepted perfusion of vasoconstrictor substance,the stoped bleeding immediately occured in 100% and 82.7% respectively.Bleeding recurrence was 3 cases in the patients with arterial embolization one week later and 25 cases of the patients with perfusion of vasoconstrictor substance forty-eight hours later.Conclusion To treat the digestive tract bleeding by arterial embolization or vasoconstrictor substance perfusion are safe and effective hemostatic ways during emergency angiography.Though the bleeding recurrent rate is high after vasoconstrictor substance perfusion,these ways can race against time for surgical operation.

Objective To evaluate efficacy and mechanism of Anluohuaxian pilule combined with interferon-γ in the treatment of schistosomal liver fibrosis. To preliminarily study on the relationship of pigment deposition in liver and schistosomal liver fibrosis. Methods Thirty Kunming mice were divided into the normal control group, the infection control group and the combination of Anluohuaxian pilule and Interferon-γ treated group. Schistosomal liver fibrosis model was established by infection with 40 Schistosoma japonicum cercariae. The treated group was treated by combination of Anluohuaxian pilule and Interferon-γ for 8 weeks. The changes of pigment deposition and hepatic egg granuloma in Schistosoma japonicum infected mice were observed. Expressions of collagen Ⅰ and Ⅲ were detected by immunohistochemistry. Transforming growth factor (TGF)-β1 was detected by fluorescent polymerase chain reaetion(PCR). Histopathology and computer image analysis were applied to evaluate the change in the liver tissues. Results The amount of pigment deposition in liver was related to the expression of TGF-β1 mRNA (correlation coefficient = 0. 8). Compared to the infection control group, combination of Anluohuaxian pilule and Interferon-γ can lessen hepatic fibrosis(P<0.05). The combination therapy can also make pigment deposition less and hepatic granuloma smaller than the infection control group(P<0. 05). Conclusions Pigment deposition in liver is related to the expression of TGF-β 1. Combination of Anluohuaxian pilule and Interferon-γ can lessen hepatic fibrosis in mice infected with Schistosoma japonicum. It's one mechanism to of the combination therapy down-regulate the expression of collagen Ⅰ, Ⅲ and TGF-β 1.
