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.

OBJECTIVE To establish the mechanism for monitoring,standardizing and alarming of relative risk factors to reflect the tendency of hospital infection.METHODS Data of hospital infection during six years were surveyed and analyzed completely.The prevalence baseline of hospital infection was chosen as the value to assess the control rate of hospital infection.The alarm value was set on the baseline.RESULTS The hospital infection revalence baseline and alarm value were used to assess the quality of infection control in whole hospital and each department objectively and accurately.These values could be also used to assess the effect of control of hospital infection among departments.They also could be used to survey the tendency of hospital infection and determine prevalence and outbreak of hospital infection.CONCLUSIONS Prevalence baseline and alarm value for hospital infection are valuable for preventing hospital infection and its outbreak.

A method of derivatization at injection port following three phase hollow fiber microextraction with tetramethylammonium hydroxide (TMAH) as a dual-function reagent, for the simultaneous determination of salicylic acid, p-hydroxybenzoic acid, cinnamic acid, vanillic acid, p-coumaric acid and ferulic acid in beers by gas chromatography was developed. Phenolic acids were extracted from aqueous samples to a thin layer of organic solvent ( hexyl acetate) phase impregnated into the pores of the hollow fiber wall, and then back extracted to an acceptor solution (TMAH) located inside the lumen of the hollow fiber. Upon injection, the phenolic acids were derivatized to their methyl esters in the GC injection port. Several parameters related to the derivatization and extraction efficiency were optimized. The optimized conditions were as follows: hexyl acetate was used as the extraction solvent, an aqueous solution of TMAH (5% W/ V) was used as the derivatization reagent and acceptor phase, the pH value of donor phase was 2. 0, the concentrations of NaCl was 25% W/ V, the stirring rate was 500 r/ min, the extraction time was 40 min. Under the optimal conditions, the linear range of phenolic acids was 0. 50 -15. 00 mg / L, the limits of detection were 0. 05 -0. 18 mg / L. The proposed method was applied to the determination of the phenolic acids in beers. Vanillic acid, p-coumaric acid and ferulic acid were found in the beer samples, others were not detected. The spiked average recoveries were 90. 1% -106. 8% and RSD% was less than 5. 9% (n =3). The method is suitable for the determination of phenolic acids in beers.

Objective To compare the clinical efficacy of laparoscopic repair of laparoscopic transabdominal preperitoneal(TAPP)and Lichtenstein tension-free repair herniorrhaphy in the treatment of recurrent inguinal hernia in adults,and to explore the clinical advantages of TAPP in the treatment of recurrent inguinal hernia.Methods A retrospective analysis was conducted in 54 adult patients with recurrent inguinal hernia from December 2010 to January 2015.The patients were randomly divided into TAPP group and Lichtenstein group.The operation time,intraoperative bleeding volume,postoperative hospitalization time,cost of hospitalization,postoperative complications,early postoperative pain and the recurrence of hernia were compared between the two groups.Results All patients were successfully completed surgery.The operation time of TAPP group (47.2 ±9.4)min was significantly shorter than (73.1 ±10.4)min of Lichtenstein group (t=-2.503,P=0.034).The median amount of bleeding during operation of TAPP group was 40(15 -110)ml,which was significantly less than 73(11 -130)ml in Lichtenstein group (t=-6.018,P=0.000). Postoperative hospital stay of TAPP group[(6.5 ±1.4)d]was shorter than (8.2 ±1.6)d of the Lichtenstein group (t=-2.613,P=0.028).Early postoperative pain score of TAPP group[(1.8 ±1.2)points]was better than (2.9 ± 1.4)points in Lichtenstein group (t=-7.006,P=0.000),the difference was statistically significant.However,the hospitalization cost of TAPP group[(8 842.8 ±415.2)yuan]was higher than (6 676.9 ±327.6)yuan of the Lichtenstein group,the difference was statistically significant(t=6.782,P<0.05).In TAPP group,2 cases had complications after operation,which were less than 5 cases of Lichtenstein group.Postoperative follow up ranged from 6 to 48 months,1 case of recurrence in Lichtenstein group,the recurrence rate was 3.8%.There was no recurrence in the TAPP group.Conclusion TAPP has the advantages of short operation time,less bleeding,rapid postoperative recovery,less postoperative pain and so on.It can be used as a recommended procedure for the treatment of recurrent inguinal hernia in adults.
