Vascular hyperpermeability is a cardinal feature of inflammation or burn in which an array of inflammatory mediators can cause such changes in the microvessels. The functional measures of microvascular exchange that represent the properties of microvascular walls are the permeability coefficients which have been reported from measurements on intact whole organisms (including human subjects), on perfused tissues and organs, on single perfused microvessels, and on monolayers of cultured microvascular endothelial cells. In this review, we summarize some experiments of vascular permeability in individually isolated perfused microvessels. [

Objective: To screen out serum protein profiling of polycystic ovary syndrome(PCOS) by surface - enhancedlaser desorption/ ionization time of flight mass spectrometry (SELDI-TOF MS) for discovering the discriminatory proteins. Methods: Thirty one women with PCOS and thirty healthy women were detected by Weak Cation Exchange(WCX2)chip. ProteinChip reader and Biomarker Wizard software from Ciphergen Inc were combined with a bioinformatics method (support vector machines, SVM ) to analyze protein fingerprinting. Results: There were 4 proteins which were obviously different between the PCOS group and the control. Three of them were up-regulated, and one down-regulated. To set up a analysis model by SVM using the 4 proteins could successfully distinguish between PCOS and the normal control. The corresponding sensitivity, specificity and positive predict value were 86.7%, 83.3%, 87.2%, resectively. Conclusion: Using ProteinChip technology can screen out serum discriminatory proteins quickly and efficiently. Combined with SVM, an optimal fingerprinting model has been set up, which can easily predict PCOS. In disease state of PCOS, there are significant variations which consist of four proteins. To investigate those four discriminatory proteins, especially the protein m/z 6 628 may be of benefit to pathogenic study and the development of biomarkers for PCOS.

Objective To observe the injury of myocardium and to investigate the role of oxidative stress after limbs ischemia reperfusion in rats. Methods 20 male healthy Wistar rats were randomly divided into 2 groups: control group(C) and ischemia-reperfusion group (IR). The biochemical methods were used to measure the contents of malondialdehyde (MDA), myeloperoxidase (MPO), ATP, lactic acid (LD) and ATPase of myocardium. The levels of creatine kinase (CK) and creatine kinase MB isoenzyme (CK-MB) in plasma were also observed. The morphologic changes of myocardium were observed with microscope. Results It was found that after rats’ limbs suffering from ischemia-reperfusion, the level of ATP decreased, the activities of three kinds of ATPase (Na~+-K~+-ATPase, Ca~ 2+ ATPase and Mg~ 2+ ATPase) decreased in different degree (P

The control group was treated with TPN parenteral alimentation. On this basis, the treatment group was treated with Yiqihuoxue decoction and mental intervention. The clinical effects were observed in both groups after the treatment. Results The total effective rate was 54.55% and 100% in the control group and the treatment group respectively, showing statistic difference(P=0.00625 ＜0.01).Conclusion It was effective to treat remnant stomach paralysis syndrome with Yiqihuoxue decoction, TPN parenteral nutrition and mental intervention.

Objective:To investigate the impact of adding human menopausal gonadotropin (hMG) for in vitro fertilization-embryo transfer pregnancy outcomes in a standard population of non-advanced age with normal ovarian reserve function using a long follicular phase protocol.Methods:Clinical data of 489 patients with normal ovarian reserve function, who were admitted from January 2018 to January 2020 in the Affiliated Hospital of Guizhou Medical University and underwent in vitro fertilization for the first time with the long follicular phase protocol in fresh cycles, were retrospectively analyzed. The patients were divided into three groups according to whether or not to add urine-derived hMG and the timing of addition: non-addition group (group A), medium-term hMG group (group B1), whole course hMG group (group B2); the laboratory parameters of each group were observed, and the effect of ovulation induction drugs and pregnancy outcomes were compared.Results:The ages of B1 and B2 groups were significantly higher than that of group A ( P=0.019 and P=0.011). The basal FSH level of group B2 was significantly higher than those of group A and group B1 ( P<0.01 and P=0.006), and the basal FSH/LH ratio of group B2 was significantly higher than that of group B1 ( P=0.009). Antral follicle counts of group A and group B1 were significantly higher than that of group B2 ( P=0.007 and P=0.017). The superior embryo rate of group B2 [(47±27)%] was significantly higher than that of group A ( P=0.017). The embryo implantation rate of group B1 was significantly lower than those of group A and group B2 ( P=0.043 and P<0.01). The clinical pregnancy rate of group B2 [76.7% (155/202)] was significantly higher than those of group A ( P=0.039) and group B1 ( P<0.01). The live-birth rate of group B2 [67.3% (136/202)] was significantly higher than those of group A ( P=0.017) and group B1 ( P=0.001). Conclusions:For non-advanced aged patients with normal ovarian reserve function, the long protocol of follicular phase is suitable for those with relatively low ovarian reserve function. Adding hMG in the whole course of ovulation induction after gonadotropin-releasing hormone agonist reduction could improve the pregnancy outcomes by improving the quality of embryos.

Total glucosides of paeony ( TGP ) , an extract of Paeonia Lacti-flora Pall were investigated for its effect on the synthesis of leukotriene B_4 ( LTB_4 ) by peritoneal macrophages ( PM?). LTB4, generated by 10~9~15 ? 10~10/L PM? with ionophore A_23187 , were measured with RP-HPLC. Suppression of releasing LTB_4 from PM? by TGP ( 100 mg/L ) was as much as the same dose of Flufenamic acid, but the action of TGP was slower. TGP significantly inhibited the synthesis of LTB_4 by PM? in a dose-dependent manner. The concentration of TGP required to obtain 50% inhibition ( IC_50 ) of formation of LTB_4 was 0.66mg/L. The data suggested antiinflam-matory and immunomodulatory action of TGP were related to its suppression of releasing LTB_4
