As an important member of metabotropic glutamate receptors (mGluR), metabotropic glutamate receptor 1 (mGluR1) plays an important role in the signal transduction of central nervous system. Selective mGluR1 antagonists can block the signaling pathway activated by mGluR1 and exert a series of physiological actions including analgesia, antianxiety, antidepression, etc. Currently, the discovery and modification of selective mGluR1 antagonists have become a hot research focus. This paper reviews the structural catalogs of selective mGluR1 antagonists and their structure-activity relationships in the last decade.

BACKGROUND:The preparation of recombinant human epidermal growth factor (rhEGF) and basic fibroblast growth factor (bFGF) has been clinical y used in the repair of ocular surface trauma. However, the concentration of these growth factors that achieve the maximal healing effect and the comparison of two kinds of growth factors on promoting wound healing are stil controversial.
OBJECTIVE:To investigate the effect of rhEGF and bFGF on the cloning of human corneal epithelial cells.
METHODS:The human corneal epithelial cells cultured in vitro were interfered with rhEGF and bFGF under different concentrations. The proliferation of human corneal epithelial cells was detected using MTT assay after 3, 5, 7 days of growth factors treatment. Plate clone formation assay was applied to observe the morphology of cellclone and analyze clone formation rate of human corneal epithelial cells.
RESULTS and CONCLUSION:MTT value shows that 10μg/L rhEGF and 10μg/L bFGF on day 5 were the most powerful concentration. The clone formation rate of human corneal epithelial cells after treated with 10μg/L rhEGF was higher than that with 10μg/L bFGF (P=0.02). The results confirmed that both rhEGF and bFGF could promote the proliferation and increase clone formation ability of human corneal epithelial cells. 10μg/L rhEGF for 5 days achieves the best effect on promoting clone formation of human corneal epithelium cells.

Objective To evaluate the clinical significance of the detection of the Human Papilloma Virus (HPV) DNA typing in therapy of cervical diseases. Methods 780 cases have been studied. These cases which showed HPV-DNA positive and were diagnosed by biopsy as cervical cancer or cervical intraepithelial neoplasia( CIN Ⅰ-Ⅲ) were treated by operation or physical therapy. And 6 months and 12 months after the treatment,TCT and HPV DNA test were carried out. Results The prevalence of HPV-DNA types among the 780 cases descended from HPV 16 to 52,58,18,33 and 31. Detection rates of HPV-52 and 58 were highest among the patients with CIN Ⅰ. In patients with CIN Ⅱ,CIN Ⅲ,carcinoma in situ and invasive carcinoma,the positive rate of HPV-16 was obviously higher than other genotypes,and the difference was significant (P＜0. 01 ). 520 cases were followed-up after treatment,we found that HPV-DNA subsided within 3 months to 1 year in 432 cases. 88 cases still showed the HPV-DNA positive, among this group 48 cases were cytology diagnosed as normal or inflammation,but 14 cases were ASC-US,22 cases were LSIL and 4 cases were HSIL. Cytology abnormal cases were mere often detected in patients with persistent HPV-positive than in patients with HPV-negative. Conclusion Referring patients with cervical diseases the common HPV genotypes are 16,52,58,18,33 and 31. Especially HPV-16 are closely related with cervical cancer and high-level cervical intraepithelial neoplasis. HPV-DNA turn negative in most patients in 12 months after treatment. Persistent infection of HPV-DNA is related with the pathological changes persist.

Objective To evaluate the value of computed tomography(CT)in diagnosing abdominal tuberculosis.Methods CT features of abdominal tuberculosis proven histopathologically or by antituberculous therapy in 16 cases were retrospectively analysed.There were 8 men and 8 women,the age ranged from 20 to 66 years,mean age was 36.4 years.Results The most common CT features of abdominal tuberculosis were:lymphadenectasis(n=11),mesenteric masses(n=6),ascites(n=6,all were loculated),omental thickening(n=7),bowel wall thickening(n=6),pleural fluid(n=2),and pancreatic involvement(n=1).Tuberculous lymphadenosis(mainly the mesentery and peripancreatic lymph nodes involved)had typical CT findings including circular or multilocular enhancement,calcification of lymph nodes,abdominal lymph nodes involved more than that of retroperitoneum and peritonitis(high dense ascites,patchy or nodular lesions in the mesentery and omentum,and intestinal adhesion).Conclusion CT findings in combination with clinical symptoms and laboratory test can improve the diagnosis of abdominal tuberculosis.
