Systematic pharmacological evaluation of material basis for the efficacy of Chinese herbal formula is one of the key issues in Chinese materia medica(CMM),which is in urgent need of solution.However,its scientific connotation is still controversial in academic circles.The material basis for the efficacy of Chinese herbal formula is the total non-endogenous bioactive compound(derived either directly or indirectly from this formula) exerting the therapeutic effects,which is generated by the interaction of the formula with human body and reaches certain concentration in the target organs or tissues.Systematic evaluation of material basis for the efficacy of Chinese herbal formula is the cornerstone of modernization and internationalization of CMM,while the quality control of CMM is its prerequisite.

Objective To explore an effective therapy for post-operative urine retention. Methods A total of 264cases were randomly recruited into a intervention group (135 cases) and a control group (129 cases). The intervention group was treated with acupuncture and acupoints massage, and the control group was treated with conventional therapy. Results The total effective rate of was 97.04% and 77.52% in the intervention group and the control group respectively, showing significant difference (χ2=28.657, P＜0.01); The average time for the first time urination of two groups was 24.38min and 35.41 min respectively, also showing significant difference (t= -14.552, P＜0.01).

The proliferation of vascular smooth muscle cells is closely related to the pathogenesis of a variety of diseases, such as atherosclerosis, hypertension, diabetes, vascular restenosis, and etc. A proper model for smooth muscle cell proliferation can be served as an important tool for exploring the molecular mechanisms of smooth muscle cell proliferation and the screening of potential inhibitory agents. Various factors can induce the proliferation of smooth muscle cells with different mechanisms and pathological significance. The ox-LDL, AGEs, angiotensin II (AngⅡ), high glucose, tumor necrosis factor (TNF) and etc. have been successfully applied in the establishment of smooth muscle cell proliferation model. This article summarized the most commonly used models for smooth muscle cell proliferation. The inhibitory effects of Chinese herbal medicine, especially the isolated pure compounds were discussed. It was aimed to provide references for the screening of smooth muscle cells based medications as well as studies on related research and development of Chinese herbal medicine.

OBJECTlVE To explore the mechanisms of tau hyperphosphorylation induced by calyculin A ( CA) in neuroblastoma cells and the effect of melatonin. METHODS N2a cells were treated with CA 5 nmol·L-1 , or CA with melatonin 50 μmol·L-1 , or CA with vitamin E ( Vit E ) 50 μmol·L-1 for 12 h. The level of tau phosphorylation at Ser422 ( recognized by R145d antibody) site and the level of phosphorylated c-Jun N-terminal kinases ( p-JNK ) and phosphorylated mitogen-activated protein kinase kinase 4 ( p-MKK4 ) were detected with immunoblotting, the level of malondialdehyde ( MDA ) was assayed with fluorimetry, and the activity of p38-mitogen activated protein kinase ( p38MAPK ) was assayed by radioimmunobloting. RESULTS CA treatment increased the level of phosphorylated tau at Ser422 site (1.70±0.19, 1.0, P<0.01), and melatonin attenuated the effect of CA (0.98±0.12, 1.70± 0.19, P<0.01). ln addition, CA treatment increased the level of MDA (μmol·g-1 protein:0.241±0.006, 0.141±0.006, P<0.01) and melatonin antagonized the increase of MDA induced by CA (μmol·g-1 protein:0.172±0.004, 0.193±0.005, 0.241±0.006, P<0.01) . CA treatment increased the level of p-JNK (1.91±0.27, 1, P<0.01) and p-MKK4 (1.81±0.09, 1, P<0.01) and melatonin antagonized the effect of CA induced increase of p-JNK (1.11±0.15, 1.91±0.27, P<0.01) and p-MKK4 (1.14±0.06, 1.81±0.09, P<0.01) without changing the level or activity of p38MAPK. Both JNK inhibitor ( SP600125 ) and MKK4/JNK transduction pathway inhibitor antagonized CA induced tau phosphorylation at Ser422 site and JNK phosphorylation. CONCLUSlON lnhibiton of JNK phosphorylation is possibly involved in the protection of melatonin on CA-induced tau hyperphosphorylation at Ser422 site.
