1.Development of internet-based home tele-monitoring system for fetus
Chinese Medical Equipment Journal 1989;0(02):-
The internet -based home tele -monitoring system for fetus has the functions of monitoring fetal heart and movement, analysis and alarm. With this system, data related to fetuses can be shared and real -time analyses and suggestions from doctors can be available. Current network system is involved in, and thus it's inexpensive and practical.

Objective: To study the serum interleukin-37 (IL-37) level changes in patients with acute coronary syndrome (ACS) and to explore the relationship between IL-37 and coronary atherosclerotic plaque.
Methods: Our research included 3 groups. ACS group, n=60, SAP (stable angina pectoris) group, n=30 and Control group, the subjects with normal coronary artery, n=15. The peripheral serum levels of IL-37 were examined by ELISA and the differences were compared among different groups.
Results: ① The serum levels of IL-37 at admission were as ACS group < SAP group < Control group, P<0.05.②Intervention could transitionally decrease IL-37 level in SAP group. With 4 weeks treatment, IL-37 levels were signiifcantly increased in both ACS group and SAP group than admission time, while they were still lower than Control group, P<0.05.③The serum level of IL-37 at admission was negatively related to IL-18 (r=-0.79, P<0.05), the ratio of IL-18/IL-37 were as ACS group>SAP group>Control group, P<0.05.④In ACS group, IL-37 level was negatively related to GRACE score (r=-0.71, P<0.05), the ratio of IL-18/IL-37 was positively related to GRACE score (r=0.73, P<0.05).⑤The diagnosis of ACS could be basically excluded if the patients with IL-37>77ug/L.
Conclusion: The serum IL-37 might be involved in the inlfammatory process in ACS patients, it could be expected as an index for ACS monitor and evaluation in clinical practice.

OBJECTIVE: To reveal the characteristics of gene expression in adrenal gland of H22 tumor mice with typical syndromes and in different liver cancer stages. METHODS: By the quantitative four diagnosis and syndrome differentiation methods and GeneChip Mouse Exon 1.0 ST Array, we observed adrenal gland gene expression in H22 tumor mice with pathogenic factor-toxin predominance syndrome and qi deficiency syndrome in the earlier stage, yang-qi deficiency syndrome in the intermediate stage, and qi-yin-yang deficiency syndrome in the advanced stage. Genes highly expressed and remarkably different were analyzed in this study. RESULTS: A total of seventy-three up-regulated coincident genes and twenty-six down-regulated coincident genes in different stages were investigated in the study. Up-regulated coincident genes included Hp, C3, Anxa1, Procr, C2, Il4ra, Cd14, Ptprc, Cd52, C4b, Eno3, Xdh, Gpx3, and so on. Down-regulated coincident genes included nervous system function-related genes such as Plp1, Mbp, Aldh1a1, Cck, Atn1, genes associated with electrolyte metabolism such as Aldh1a1 and Slc22a17, genes related to signal transduction such as Cxcr4, Spag5 and Stmn3, etc, and genes related to transcriptional control and protein biosynthesis such as Hspa1a, Dnajb1, Thra, Hhex and so on. CONCLUSION: With the development of the tumorigenesis, the symptoms and signs and differentially expressed genes in adrenal gland of H22 tumor mice can be measured. Up-regulated and down-regulated coincident genes may be the features of H22 tumor mice different from those of normal mice.

OBJECTIVE: To observe the improvement effects of water extract of Glycyrrhiza uralensis on acute hepatic injury caused by triptolide and its effects on the levels of IL-10 and TNF-α in rats. METHODS: A total of 60 healthy male SD rats were randomized into blank control group, model group, positive control group (magnesium isoglycyrrhizinate) and G. uralensis water extract low-dose, middle-dose and high-dose groups. Blank control group and model group were given isochoric normal saline intragastrically; positive control group was given Magnesium isoglycyrrhizinate liquid intragastrically (13.5 mg/kg); G. uralensis water extract low-dose, middle-dose and high-dose groups were given G. uralensis water extract intragastrically 1 mL (120, 240, 480 mg/kg, by the amount of extract), qd, for consecutive 7 d. At 8th day of administration, model group, positive control group and G. uralensis water extract groups were given Triptolide liquid intragastrically (0.6 mg/kg) to establish acute liver injury model. HE staining was used to detect the pathological changes of liver tissue in rats. The activities of ALT and AST in serum were determined by enzyme coupling reaction. The protein expression of IL-10 and TNF-α in liver tissue were analyzed by Western blotting. RESULTS: Compared with blank control group, obvious pathological changes of liver tissue in rats were observed in model group; serum activities of ALT and AST, the protein expression level of TNF-α in liver tissue were increased significantly, while the protein expression level of IL-10 was decreased significantly (P<0.01). Compared with model group, pathological changes of liver tissue were relieved significantly. Except for the activity of AST in serum of rats in G. uralensis water extract low-dose group, the activities of ALT and AST in serum, the protein expression level of TNF-α in liver tissue were decreased significantly in G. uralensis groups, while the protein expression level of IL-10 in liver tissue was increased significantly (P<0.05 or P<0.01). CONCLUSIONS: G. uralensis water extract can relieve triptolide-induced acute liver injury in rats, the mechanism of which may be associated with expression down-regulation of pro-inflammatory factor TNF-α and expression up-regulation of anti-inflammatory factor IL-10.
