Objective To study the effect of water extract of ephedra on hepatic injury induced by cisplatin in rats. Methods Forty rats were randomly divided into the blank group, model group, and ephedra water extract was divided into the low dose group, medium and high dose group. Ephedra water extract in the low, medium dose group, high dose group were 100, 200, 400 mg/kg. The normal saline of equal volume was used in the blank group and model group, once a day for 10 days. In addition to the blank group, the other groups were given cisplatin (8 mg/kg) on the 6th day to establish the model of liver injury in rats. The changes of body weight, serum ALT, AST and liver MDA, NO, SOD, GSH were detected by biochemical method. The pathological changes of liver tissue were observed by the staining. Results On the 3rd day and 5th day after administration of cisplatin, the body weight of the rats in the low, medium and high dose group were significantly higher than that in the model group (P<0.05 or P<0.01). Compared with the model group, the serum AST (328.00 ± 168.00 U/L, 297.00 ± 139.00 U/L vs. 409.00 ± 364.00 U/L), ALT (122.00 ± 76.00 U/L, 97.00 ± 64.00 U/L vs. 198.00 ± 156.00 U/L) in the medium-, high- dose group significantly decreased (P<0.05 or P<0.01). The content of SOD (34.98 ± 7.40 U/mg, 41.80 ± 8.10 U/mg vs. 12.70 ± 3.10 U/mg), GSH (16.90 ± 1.70 mg/g, 22.70 ± 3.70 mg/g vs. 9.90 ± 1.30 mg/g) in the medium-, high- dose group significantly increased,while the content of MDA (3.20 ± 0.60 nmol/ml, 2.20 ± 0.30 nmol/ml vs. 4.30 ± 0.70 nmol/ml), NO (0.90 ± 0.10 μmol/L, 0.80 ± 0.20 μmol/L vs. 1.20 ± 0.30 μmol/L) significantly decreased (P<0.05 or P<0.01). Conclusion The ephedra water extract can protect the liver injury induced by cisplatin in rats.

Coronary heart disease(CHD)is a common cardiovascular disease in clinic,which can be classified as"chest qi-obstruction"and"heart pain"in traditional Chinese medicine.Professor LI Yan believes that CHD can be differentiated as the syndrome of deficiency in origin and excess in superficiality,and the deficiency in origin is characterized by the deficiency of spleen and the failure of spleen and stomach in transportation,while the excess in superficiality manifests as the obstruction of visible pathogens such as phlegm turbidity,blood stasis,qi stagnation,and cold accumulation.The clinical treatment should focus on regulating the spleen and stomach,using Astragali Radix,Atractylodis Macrocephalae Rhizoma,Codonopsis Radix,Schisandrae Chinensis Fructus to strengthen the spleen and nourish the heart in order to treat the root cause.Moreover,therapies of activating yang to remove turbidity,activating blood to remove stasis,soothing liver to rectify qi,and warming yang to dissipate the cold can be adopted.Therefore,the symptom and root cause will be treated simultaneously,the unblocking and supplementing effect will be achieved,and then the spleen-qi is vigorous,the heart qi is in abundance,the blood stasis and the phlegm are removed,and the chest yang can be stretched.As a result,the heart vessels are unblocked,and the symptoms of chest qi-obstruction will be relieved.Professor LI Yan's experience from the perspective of spleen and stomach can provide reference for the clinical diagnosis and treatment of CHD with traditional Chinese medicine.

[摘 要] 宫颈癌是一种发病率和转移率均较高的妇科癌症。尽管手术、放射、化学治疗在宫颈癌治疗中取得了显著的临床效果，但仍存在一定的局限性，因此亟需新的治疗药物。近年研究发现，Wnt/β-catenin 信号通路在宫颈癌发生发展、转移、耐药等过程中起关键性作用。Wnt/β-catenin信号途径参与宫颈癌的发生发展和远处转移及对化疗药物的耐受性；天然化合物如中药白藜芦醇和黄芩素等及合成化合物如伊曲康唑等均可通过此信号通路发挥抗宫颈癌的作用；非编码RNA和一些蛋白分子均可以通过此通路影响宫颈癌的发生发展。研究说明，Wnt/β-catenin信号途径是宫颈癌治疗的潜在靶点。本文归纳宫颈癌中Wnt/β-catenin信号途径的作用，以期为宫颈癌的临床研究与新药开发提供参考依据。
