BACKGROUND:Several studies have demonstrated that the physiological process of the ovary, including folicle development, maturity, ovulation, corpus luteum formation and regression, is related to the formation of extracelular matrix. However, matrix metaloproteinase 9 and connective tissue growth factors had a close relationship with the formation of extracelular matrix. OBJECTIVE:To investigate the relationship between the expression of connective tissue growth factor and matrix metaloproteinase 9 and polycystic ovary syndrome. METHODS:The female SD rats with regular estrous cycle were randomly divided into control and model groups. The rats in the model group were intragastricaly with letrozole to establish the model of polycystic ovary syndrome, while the rats in the control group were intragastricaly with the same amount of carboxymethyl celulose. When the natural law of estrous cycle of rats in the model group did not exist and consecutive interval appeared, rat serum and ovarian tissues were colected. Rats in the control group were detected by colecting specimen in the interval. RESULTS AND CONCLUSION:Radioimmunoassay and immunohistochemical staining results showed that compared with the control group, the expression of serum luteinizing hormone, serum prolactin levels, connective tissue growth factor in preantral folicles theca cytoplasm, connective tissue growth factors in folicular basement membrane cytoplasm, connective tissue growth factors in albuginea and matrix metaloproteinase 9 in corpus luteum significantly increased (P < 0.05). The contents of folicle stimulating hormone and serum estradiol, and expression of matrix metaloproteinase 9 in folicular basement membrane significantly decreased (P < 0.05). The results indicate that connective tissue growth factors may be related to the excessive growth of smal folicles and ovulation disorders in polycystic ovary syndrome, while matrix metaloproteinase 9 may be related to ovulation disorders in polycystic ovary syndrome.

Hyperphenylalaninemia is a common group of inherited metabolic diseases.It is characterized by the increased concentration of plasma phenylalanine.The metabolism of phenylalanine requires phenylalanine hydroxylase and coenzyme tetrahydrobiopterin.These enzymes cannot function normally if there is any mutation in their encoding genes.Children suffering from hyperphenylalaninemia without promptly treatment may present mental development delay and other serious nervous system sequelae.With the technical improvement of molecular genetics,there have been many progresses in the study of genetic diagnosis,genotype-phenotype correlation and gene therapy of hyperphenylalaninemia.This article reviews the history and classification of hyperphenylalaninemia,the characteristics of gene mutation,the methods of genetic diagnosis,the genotype-phenotype correlation,and the progress of new therapy.

Objective:To study the effect of insulin like growth factor 1 and insulin on the promoter activity of human ?1(Ⅰ) procollagen (COL1A1) gene and the influence of tumor necrosis factor ?(TNF?), interferon ? (IFN?) and interferon ?(IFN?) on the effect Methods:Two deletion constructs,pCOLH0 27 and pCOLH2 5 ,containing portions of 5' flanking region of the gene ( 268～+42 bp and 2 483～+42 bp respectively) ligated to the chloramphenicol acetyltransferase (CAT) reporter gene ,were transiently transfected into human skin fibroblasts The cells were subsequently treated with IGF 1 or insulin, and TNF? or IFN? or IFN? The CAT activity was assessed 24 h after the cytokines added Results:The results showed that 13 nmol/L IGF 1 caused 3 68 fold and 4 04 fold increase in the CAT activity of pCOLH0 27 and pCOLH2 5 respectively and that 2 5 ?mol/L insulin caused 3 69 fold and 3 93 fold increase in the activity of the two plasmids respectively TNF?,IFN? and IFN? reduced IGF 1 or insulin induced promoter activity of pCOLH2 5 Conclusion:IGF 1 and insulin could increase the promoter activity of the human (COL1A1) gene TNF?,IFN? and IFN? could suppress the promoter activity induced by IGF 1 and insulin

Objective To investigate the correlation between stenosis or occlusion of vertebralbasilar artery and the location of infarctions in pontine. Methods All 139 patients with acute pontine infarction who were admitted to the Department of Neurology,Xuanwu Hospital,Beijing,during February,2005 and September,2007 were studied. All patients received the examinations of head MRI and digital subtraction angiography (DSA). Patients with possible cardiac embolism were excluded from the study. All the cases were then divided into four groups: A( paracentral artery group); B (short rotary artery group); C (long rotary artery group) and D (combined group). Results In all 139 cases,78 cases (56. 1% ) were in A group,3 (2. 2% ) in B group,7 (5.0%) in C group and 51 (36.7%) in D group. Fifty-six cases (40. 3% ) have occlusion in vertebral artery,60 cases (43.2%) have stenosis of vertebral artery. Cases having stenosis or occlusion in basilar artery are 14 cases (10. 1% ) each. Sixteen cases (11.5%) have unimpaired vertebral-basilar artery. A group is related to occlusion of vertebral artery and basilar artery and unimpaired artery ( x2 =3. 945,6. 824,4. 485 ,P = 0. 043,0. 021,0. 041 respectively). D group is related to occlusion of basilar artery ( x2 = 10. 952,P = 0. 006). Logistic binary analysis found that A group is more related with occlusion of vertebral artery ( OR = 2. 261 ),while D group is more related to occlusion of basilar artery ( OR = 15. 750). Conclusions There is a significant correlation between stenosis or occlusion of vertebral-basilar artery and the locations of infarctions in pontine. The physicians are suggested to perform the examinations on cerebral vessels such as brain MRI or DSA in patients with infarctions in pontine.

Currently, the model of the research evaluation system of traditional Chinese medicine (TCM) is set up through imitating that of western medicine. The application of quantitative research to TCM does promote the advance of modernization of TCM, which explore the part of TCM that can be measured in quantitative method. However, TCM has a background of profound philosophy and culture. The priority of TCM can not be expressed through quantitative research alone. On the contrary, qualitative research is more suitable to most research area of TCM. In TCM clinical research, the priority of TCM should be fully explored. It is very significant to set up the effectiveness evaluation system of TCM, especially by applying qualitative research to the diagnosis and the evaluation of treatment results and combining quantitative research.
