Objective To discuss the relationships of the genotype of cytochrome P450 2C19 (CYP2C19) gene and and clopidogrel responsiveness.Methods The study enrolled 110 patients with acute myocardial infarction who were treated with clopidogrel in Tiantan Hospital of Beijing from November 2012 to May 2014.Patients were treated by aspirin and clopidogrel.CYP2C19 polymorphisms were detected by genotype testing kits.Platelet inhibition rates were measured by thrombelastography to represent the antiplatelet effect of clopidogrel.The platelet inhibition rates of clopidogrel were compared among different genotypes.Results Compared with carriers of CYP2C19 * 2 or * 3 reduced-function allele,CYP2C19 * 1 wild type had higher platelet inhibition rate of clopidogrel ((35.73 ± 19.29)％ vs.(48.30± 20.84)％),and the difference was significant(t =3.264,P＜0.05).There was no difference between intermediate metabolizer((35.72± 19.27)％) and poor metabolizer((35.75±19.89)％;P＞0.05).The frequency of wild-type homozygotes CYP2C19 * 1/* 1 was higher in responders than in low responders(frequency of low reaction group CYP2C19 * 1/* 1 14 cases (40.0％),* 1/.2 10 cases(28.6％),* 1/* 3 4 cases(11.4％),* 2/* 2 5 cases(14.3％),* 2/* 3 2 cases (5.7％),frequency of reaction group were 45 cases (60.0％),15 cases (20.0％),4 cases (5.3 ％),7 cases (9.3％),4 cases(5.3％);x2 =3.838,P =0.05).Conclusion Polymorphism of gene CYP2C19 is associated with different responses to clopidogrel.CYP2C19 * 2/ * 3 reduced-function allele is associated with low response to clopidogrel.

Persicae Ramulus decoction, as the first prescription in Treatise on febrile Diseases, has been recommended by physicians of successive generations. It is also the general prescription for harmonizing yingfen and weifen, yin and yang, qi and blood. Although it only consists of five herbal medicines, it has a wider range of application and more categorized formulas than other prescriptions. Though Persicae Ramulus decoction was originally formulated to treat taiyang apoplexy, it has functions beyond the treatment of exopathic diseases. This formula is also effective in treating internal diseases, surgical diseases, gynecologic diseases, paediatric diseases, etc. KE Yun-bo praised it as the No. 1 formula among ZHANG Zhong-jin's formulas as well as the general prescription for harmonizing Yin and Yang, yingfen and weifen, resolving fleshy exterior and inducing perspiration. Professor SHI Xin-de has been expert at treating intractable diseases by using Persicae Ramulus-associated prescriptions, such as Xiaojianzhong decoction and Baohe pill for children's chronic eczema, Persicae Ramulus and Puerariae Lobatae Radix decoction and Yupingfeng powder for chronic nephritis, and Persicae Ramulus and Longgu Muli decoction for insomnia. Instead of being restricted to Chinese or Western disease names, he prescribed appropriate formulas according to syndromes, thereby achieving a good efficacy.

Objective To search for the CT and MRI morphological changes in the child patients with cerebral palsy. Method The CT scranning and MRI were carried out in 150 child patients with cerebral palsy, andthe results were analysed. Results In 150 cases, 97 cases (54.6 per cent) have abnormal findings of CT scranning. Diffuse ence-phalatrophy (42 cases), encephalomalacia focus (24 cases) porencephaly (9 cases), and localized ence-phalatrophy (7 cases) ect are the common CT morphological changes in the patients with cerebral palsy.In the 53 patients with normal findings of CT scranning, MRI was carried out for 30 cases and 25 cases(83.3 per cent) were abnormal. The delayed myelinogeny of white matter of brain is the main MRI mor-phalogical abnormality. Conclusion CT scranning and MRI have important value on the etiological diagnosis for child patientswith cerebral palsy. The combination of them can improve the diagnostic accordance rate.

To explore the influence of angiotensinⅡ(AngⅡ) and aldosterone (Ald) on synthesis of collagen and activity of precollagenase secreted by cardiac fibroblasts.Sirus Red method was employed to evaluate collagen synthesis of cultured cardiac fibroblasts; typeⅠ collagen was measured by competitive ELISA; collagenase activity was tested by fluorescence spectrophotometry.At the doses of 10-9～10-7mol/L, AngⅡ could enhance gross and typeⅠ collagen production in a dose-dependent manner. Collagenase activity decreased with increasing concentration of AngⅡ. These effects of AngⅡcould be completely abolished by its receptor antagonist, saralasin. Ald might enhance gross and typeⅠ collagen production only at a higher concentration (10-7～10-8mol/L), whereas lower concentration (10-9mol/L) had no effect on it. These effects of Ald could be abolished by spironolactone,a specific Ald receptor antagonist. In addition, Ald could significantly decrease the activity of collagenase secreted from cultured cardiac fiboblasts at concentrations of 10-9～10-7mol/L within 24h，which could not be antagonized by 10-6mol/L spironolactone. The results suggested that AngⅡand Ald enhance cardiac fibroblasts collagen synthesis and inhibit collagenase activity ,resulting in net collagen accumulation resulted and acceleration of cardiac fibrosis.
