This article reports a case of severe ulcerative colitis (SUC) . On the basis of excluding the opportunistic infection, the patients failed in hormone therapy with following intestinal perforation, and received emergency surgery finally. After the surgery, the main treatment discussed by the cooperation of multidisciplinary team (MDT) was enteral nutritional support therapy with rectal anti-inflammatory therapy as adjunctive treatment, and ileal pouch anal anastomosis was performed at selected time. The patient achieved a good quality of life. The case analysis combined with literatures was conducted in order to explore the MDT diagnosis and treatment strategies of SUC.

Cronkhite-Canada syndrome (CCS) is a rare disease characterized by diffuse gastrointestinal polyps, hair and nail loss and skin pigmentation. Its pathogenesis is unknown. This article reports a case of CCS, who was effectively treated with glucocorticoid and the gene mutation of colonic adenomatous polyp was detected by genetic testing, in order to provide reference for clinical diagnosis and treatment.

[ ABSTRACT ] AIM: To observe the effect of rapamycin on the apoptosis of mouse astrocytes in vitro.ME-THODS:The astrocytes from C57BL/6J newborn mouse pups were isolated and primarily cultured.The effect of rapamycin on the viability of astrocytes was assessed by MTT assay.The mean fluorescence intensity of SYTOX?Green stain in the astrocytes was detected by fluorescence microplate reader in order to analyze the effects of rapamycin on the cell death in-duced by H2 O2 , ionomycin and/or deferorxamin.DiOC6 (3) staining was used to analyze the mitochondrial membrane po-tential of the astrocytes induced by H2 O2 .Flow cytometry analysis was used to determine the production of ROS in the as-trocytes and mitochondria by staining with H2 DCFDA and MitoSOXTM Red reagent, respectively.RESULTS: Rapamycin at concentration of 0.5 μmol/L protected the astrocytes against cell death induced by H2 O2 or deferoxamine plus ionomy-cin.Rapamycin protected the mitochondrial membrane potential of astrocytes from the injury of H2 O2 .It also reduced the production of ROS in the astrocytes and decreased the level of ROS in the mitochondria.CONCLUSION:Rapamycin re-duces the ROS overload in the mitochondria, keeps mitochondrial membrane potential safety and protects the astrocytes a-gainst apoptosis in vitro.

Objective To construct a multi-gene recombinant pcDNA3-HBsAg-p30-ROP2 expression vector and identify it preliminarily. Methods According to recombinant pcDNA3-p30-ROP2 restriction sites,HBV HBsAg gene sequences of primers were designed and synthesized to amplify target fragment,and then cloned into pcDNA3-HbsAg-p30-ROP2 expression vector. Af-ter sequencing,it was identified finally by restriction enzyme digestion and other molecular biology techniques. Results HBV HBsAg gene segment was amplified by PCR and the multi-gene recombinant pcDNA3-HBsAg-p30-ROP2 expression vector was constructed and identified to be correct as theoretical values. The PCR and restriction enzyme digestion results showed that HBsAg and p30-ROP2 gene in recombinant plasmid were confirmed by DNA sequencing. Conclusion The multi-gene recombinant pcD-NA3-HBsAg-p30-ROP2 expression vector is successfully constructed.

Objective To investigate the expression and clinical significance of AGR2 and Lgr5 in CRC and the corre-lation with clinical pathologic features. To evaluate the significance with combined detection of the clinical and patho-logical diagnosis of CRC. Methods AGR2 and Lgr5 expression were assessed in 70 cases of CRC and 20 cases of nor-mal tissues near the cancer by immunohistochemistry. Results ①The expression of AGR2 was significantly higher in CRC than that in normal tissue(68.57%vs 25.00%,P<0.01). The AGR2 expression in CRC was correlated with the de-gree of tumor differentiation and lymph node metastasis(P<0.05).②The expression of Lgr5 was significantly higher in CRC than that in normal tissue (74.29%vs 40.00%, P<0.01). The Lgr5 expression in CRC was correlated with the de-gree of tumor differentiation﹑depth of invasion and lymph node metastasis(P<0.05). ③The Area Under Curve(AUC) of combined detection of AGR2 and Lgr5 were significantly higher than detection of both alone. the difference was statis-tically significant (P all <0.05). Conclusion AGR2 and Lgr5 played an important role in the occurrence and develop-ment of CRC, the combined detection not only contribute to the judgment of tumor progression, but also provide theo-retical support for molecular diagnosis and treatment of patients with CRC .

Dyslipoproteinemia is correlated with the occurrence and development of atherosclerosis and cardiocerebral vascular diseases. The metabolism of serum lipoprotein, however, is a complicated and ordered metabolic process. On one hand, every organ, tissue and even cell of the body participates in and affects the state of serum lipoprotein dynamic balance (SLDB) in different degrees. On the other hand, SLDB is a direct factor for maintaining the normality of whole vascular system, especially the vascular endothelium system. The serum lipoprotein dynamic imbalance, as an inducement or even etiological factor, can bring about various clinical diseases. Therefore, integrated analysis is needed to appropriately assess the state of SLDB. It is suggested that serum lipoprotein dynamic imbalance syndrome should be the key risk factor for those related diseases. Serum lipoprotein electrophoretogram can ideally express the state of SLDB and be taken as a new index for cognizing the serum lipid metabolism and the function of speen-qi to distribute Jing (Essonse) in the integrated traditional Chinese and western medicine. Practice has showed that concrete integration and bilateral development should be one of the main tasks in current researches of integrated traditional Chinese and western medicine.

Objective To study the role of total flavonoids of hippophae rhamnoides in improving contactile function of stretched cardiac myocyte.Method Flavonoids were given to stretched myocytes which were proved their contractile function decline and then myocyte contractile mechanics characteristics and calcium transfer were measured.Result Flavonoids increased myocyte contractility,as indicated by myocyte shortening,velocity of shortening,peak+dL/dt and peak-dL/dt during shortening,in a concentration-dependent manner (r>0.9,P<0.001),and with no relation to the intracellular calcium transfer in the myocytes.Conclusion Flavonoids of the traditional Chinese drug hippophae rhamnoids is effective in improving the contractile function of stretched cardiac myocyte in low dosage.
