Protective effect of hyperoside on paraquat-induced acute lung injury in rats / 局解手术学杂志

Objective To investigate the protective effect and mechanism of hyperoside(HYP)on paraquat(PQ)-induced acute lung injury in rats.Methods Rats were randomly divided into the control group,the PQ group,the low-dose hyperoside group(HYP-L group),the middle-dose hyperoside group(HYP-M group)and the high-dose hyperoside group(HYP-H group),with 12 rats in each group.After 7 days of corresponding treatment,the levels of interleukin(IL)-1β,IL-6 and macrophage inflammatory protein-2(MIP-2)in bronchoalveolar lavage fluid(BALF)of rats in each group,as well as the levels of malondialdehyde(MDA)and superoxide dismutase(SOD)in lung tissue were detected.The degree of lung injury and fibrosis of rats were evaluated by hematoxylin-eosin(HE)staining and Masson's trichrome staining.The expression levels of E-cadherin,α-smooth muscle actin(α-SMA),Vimentin,and protein expression levels of nuclear factor erythroid 2-related factor 2(Nrf2),nuclear factor-κB(NF-κB)p65,p-NF-κB p65,transforming growth factor-β1(TGF-β1),Smad3 and p-Smad3 in lung tissue were detected by Western blot.Results Compared with the control group,the levels of IL-1β,IL-6 and MIP-2 in BALF of rats in the PQ group increased(P<0.05),the level of SOD in the lung tissue decreased,while the level of MDA increased(P<0.05),and the lung tissue showed obvious damage and fibrosis(P<0.05).Compared with the PQ group,the levels of IL-1β,IL-6 and MIP-2 in BALF of rats in the HYP-L group,the HYP-M group and the HYP-H group decreased(P<0.05),the levels of SOD in the lung tissue increased(P<0.05),while the levels of MDA decreased(P<0.05),and the lung tissue damages were alleviated,and the fibrosis score decreased(P<0.05).Compared with the control group,the expression level of E-cadherin in the lung tissue of rats in the PQ group decreased(P<0.05),the expression levels of α-SMA and Vimentin increased(P<0.05),the protein expression level of Nrf2 decreased(P<0.05),the protein expression level of TGF-β1 and the phosphorylation levels of NF-κB p65 and Smad3 proteins increased(P<0.05).Compared with the PQ group,the expression levels of E-cadherin in the lung tissues of rats in the HYP-L group,the HYP-M group and the HYP-H group increased(P<0.05),the expression levels of α-SMA and Vimentin decreased(P<0.05),the protein expression levels of Nrf2 increased(P<0.05),the protein expression level of TGF-β1 and the phosphorylation levels of NF-κB p65 and Smad3 proteins decreased(P<0.05).Conclusion Hyperoside effectively alleviates paraquat-induced acute lung injury in rats,and it may reduce lung oxidative stress,inflammation and fibrosis by regulating Nrf2,NF-κB and TGF-β1/Smad2/3 signal pathways.

Inspiration of the development of acupotomy therapy to acupuncture and moxibustion science / 中国针灸

The inspiration of acupotomy therapy to acupuncture and moxibustion was explored in view of the development of acupotomy device, the clinical practice model and the theoretical innovation. The results show that the acupotomy therapy develops rapidly because that the great attention has been paid to the development of the device, the communication and integration with the other disciplines and the theoretical innovation. These three aspects should also be emphasized for the development of acupuncture and moxibustion. The development of acupotomy therapy provides the beneficial inspiration to acupuncture and moxibustion science.

Discussion on knowledge structural system of modern acupuncture professionals / 中国针灸

To explore the knowledge structural system that the modern acupuncture professionals should have. The current situation of personnel training for modern acupuncture professionals was multi-dimensionally and comprehensively analyzed from course offering of higher education, laws of famous physicians growth, and discipline development features of the acupuncture and moxibustion subject, and suggestions were made to the shortages. The reasonable knowledge structural system that the modern acupuncture professionals should have included establishment of good Chinese medicine thoughts, mastery of complete Chinese medicine therapy, and ability of followup of dynamic development of subject. The reformation of course design is imperative in order to promote the reasonable knowledge structural system formation of modern acupuncture professionals.

Controlled observation on effects of different needle retaining time in scalp acupuncture on motor function in the infant of cerebral palsy / 中国针灸

<p><b>OBJECTIVE</b>To compare therapeutic effects of different needle retaining time in scalp acupuncture on motor function in the infant of cerebral palsy.</p><p><b>METHODS</b>Randomized controlled design and Jin three needle therapy were used, and the therapeutic effects of needle retaining time of 1 h and 30 min on cerebral palsy were compared.</p><p><b>RESULTS</b>After treatment for 2 months, the improvement of motor function in the group of retaining needle of lh was better than that in the 30 min group.</p><p><b>CONCLUSION</b>Prolonging the retaining needle time for sufficient stimulation amountis an important factor for achieving a better therapeutic effect in scalp acupuncture treatment of infant cerebral palsy.</p>
