Research on particular standards related to maternal fetal monitor / 中国医学装备

The safe and reliable maternal fetal monitor can provide comprehensive physiological monitoring for pregnant women and fetuses,and effectively reduce maternal and infant mortality.In the current stage,in addition to the general requirements of medical electrical equipment applicable to maternal fetal monitor in China,there is no particular standard for maternal fetal monitor.The common practice in the industry is to refer to and learn from the particular standards of multi-parameter monitor and ultrasonic Doppler fetal monitor.Based on this,the particular standards applicable to the maternal fetal monitor were researched,and the idea of formulating particular standards for the basic safety and essential performance requirements of the maternal fetal monitor were proposed to ensure the safety and effectiveness of the monitor.

Neuroprotective effect of borneol combined with astragaloside IV and Panax notoginseng saponins in cerebral ischemia reperfusion injury rat model through Notch signaling pathway / 中草药

Objective: To observe the neuroprotective effect of borneol combined with astragaloside IV (AST IV) and Panax notoginseng saponins (PNS) on cerebral ischemia reperfusion injury (CIRI) rat model through Notch signaling pathway. Methods: SD rats were randomly divided into sham group, model group, borneol (7.5 mg/kg) group, AST IV (25 mg/kg) group, PNS (10 mg/kg) group, AST IV (10 mg/kg) + PNS (25 mg/kg) group, borneol (7.5 mg/kg) + AST IV (25 mg/kg) + PNS (10 mg/kg) low dose group, borneol (15 mg/kg) + AST IV (20 mg/kg) + PNS (50 mg/kg) high dose group and edaravone (4 mg/kg) group. Rats in sham group and model group were ig 0.5% CMC-Na, edaravone group was ip drug, and the other groups were ig corresponding drugs, twice a day with an interval of 12 h. The right middle cerebral artery of rat was blocked by a suture method 2 h after last administration to establish a CIRI model. After 2 h of ischemia and 22 h of reperfusion, the eurological function scores were scored and pathological changes of ischemic cortex in brain tissues of rats were observed by HE staining. The expressions of neuron specific nuclear (NeuN) and endothelial barrier antigen (EBA) in ischemic cortex of brain tissue were detected by immunohistochemistry. The expressions of vascular endothelial growth factor (VEGF), Notch1, and intracellular domain of Notch (NICD) in ischemic cortex of brain tissue were detected by Western blotting. Results: The score of neural dysfunction and cell damage rate in model group were significantly increased (P < 0.01); The score of nerve function defect and rate of cell damage in each administration group were significantly reduced (P < 0.05, 0.01), the effect of borneol + AST IV + PNS group was better than that of single drug and AST IV + PNS group (P < 0.05, 0.01). NeuN and EBA protein expressions were significantly decreased in the ischemic cortex of model group (P < 0.01), while NeuN and EBA protein expressions were significantly enhanced in each administration group (P < 0.05, 0.01), and the effect of borneol + AST IV + PNS group was better than that of single drug and AST IV + PNS group (P < 0.05, 0.01). In model group, VEGF protein expression was increased significantly (P < 0.05), while NICD and Notch1 protein expression had no significant change. The expression of VEGF, NICD and Notch1 protein were significantly up-regulated in borneol + AST IV + PNS group (P < 0.01), and the effect of combination of three drugs was better than that of single drug and AST IV + PNS (P < 0.05, 0.01). Conclusion: Borneol, AST IV, and PNS have the effects of preventing neuronal and cerebral microvascular damage after CIRI, and the effect of combination of three drugs was better than that of single drug and AST IV + PNS, which may be related to the activation of the Notch signaling pathway and up-regulation of VEGF expression, thereby, exerting protective effects on ischemic brain tissue.

Study on the Prevention and Treatment Effect and Its Mechanism of Yinyanjing Lotion on Allergic Con-tact Dermatitis in Rats / 中国药房

OBJECTIVE:To study the prevention and treatment effect and its mechanism of Yinyanjing lotion on allergic con-tact dermatitis(ACD)in rats. METHODS:60 rats were randomly divided into blank control group,model control group,positive control group(dexamethasone)and Yinyanjing lotion high-dose,medium-dose,low-dose groups(respectively given 2-fold concen-trated solution,1-fold concentrated solution and original solution),10 in each group. Except for blank control group,rats in other groups smeared dinitrochlorobenzene in the abdomen and back(2 cm×2 cm)to induce ACD model. From the 9th of modeling,rats in each administration group were smeared 100 μL of related drugs in the back,and rats in blank control group and model control group smeared 100 μL of purified water,3 times a day,for 10 d. After administration,skin allergic reaction was scored and skin swelling degree was determined. HE staining was used to observe the pathological changes of skin. Enzyme-linked immunosorbent method was used to detect the contents of interleukin-2 (IL-2),IL-4,IL-6 and interferon γ(IFN-γ) in serum. RESULTS:Com-pared with blank control group,allergic reaction scores and skin swelling degree in model control group were significantly in-creased (P<0.01). Electron microscopy showed epidermal scab necrosis,dermal layer damage,hair follicle necrosis. Contents of IL-2,IL-4,IFN-γ in serum were significantly increased (P<0.05 or P<0.01);IL-6 content was slightly increased (P>0.05). Compared with model control group,except that the skin swelling degree,IL-4 content in serum in Yinyanjing lotion low-dose group and IL-6 content in serum in each administration group were not significantly improved,other indexes were significantly im-proved(P<0.05 or P<0.01). CONCLUSIONS:Yinyanjing lotion has certain prevention and treatment effects on ACD in rats,the mechanism may be associated with reducing the contents of IL-2,IL-4,IFN-γin serum.

Advances in the research of Hedgehog signaling pathway associated with the invasion and metastasis of tumors / 肿瘤

Hedgehog family proteins are important morphogens which mediate the development of embryo as well as the carcinogenesis in adults. Inappropriate activation of Hedgehog signaling pathway contributes to numerous human cancers. The Hedgehog signaling pathway is considered to be involved in the molecular mechanism of the invasion and metastasis of the tumors, and to facilitate the metastasis of tumors through signaling pathways interaction. It is suggested that a potential therapeutic strategy pharmacologically targeting Hedgehog-dependent tumors may be developed.
