After 40 years of development,laser crystals have established a firm foundation for solid state laser *** improvements of the crystals now on hand and the exploration of new crystals are still going on actively. 1 Development of the laser crystals now on hand 1.1 YAG YAG is a laser crystal with good property,extensive application and wide scale *** at the need of LD pumping,many new varieties of garnet have been developed,with the goal of enlarging the absorption of line *** idea of this development is chiefly as the follows:(1)Enlarge the lattice constant through substitution of cations;(2)Waiden the absorption spectrum through the vacancy of cations;(3)Using cations with host sensitization,such as Mn 2+ ,*** author has considered several optional varieties:Y 2.7 La 0.25 Nd 0.05 Al 3.5 Nb 0.9 O 12 (calculating lattice constant: a 0～1.202nm,in contrast of that of YAG: a 0～1.200nm);Y 1.5 LaMn 2+ 0.5 Al 4.5 Si 0.5 O 12 ( a 0～1.205nm);and YLaMn 2+ Al 4(Nb,V) 5+ 0.6 O 12 ( a 0～1.204nm);etc.

作者： Ling Yun Yu Kang-di Yang-fan Ding-Ying Shaojing-yu Li An-wei Feng Zhanchong(Teaching Hospital of Shanghai Medical University Shanghai First Matrnity and Infant Health Hospital (200O40)tel. 86-021-62475206-2094, Faxs 86-021-62471482)

From July 1991 to June 1996 169 cases of tubal infertility were treated by surgery combined laparoscopy and hysteroscopy. The Procedure include: Adhesiolysis of perisalpingoovaritis , dilation of fallopian tube, salpingostomy, endometriosis cantery, enucleation and puncture of endometrioma, excision of Morgani cyst. Meanwhile hysteroscopic catheterization and hydrotubaation monitoring by ***:135 cases were followed up. The mean follow-up time was 18.4 month.70 cases became pregnant (pregnant rate 51.8%). 67 of them had intrauterine Pregnancy and three cases were ectopic pregnancies. The surgery combined laparoscopy and hysteroscopy to treat tubal infertility is simple, effective, less-harmful and the patients had rapid recovery.

抑郁症患者的性激素分析

中国神经精神疾病杂志 1999年第5期25卷 271-273页

作者：李强尚翠侠马现仓陈策西安医科大学第一临床医学院精神科 710061

目的　研究抑郁症患者垂体促性腺激素及外周性激素的功能状态，探讨性激素水平改变与性有关症状和药物治疗的关系。方法　采用放射免疫法测定３０例（男１１例，女１９例）抑郁症患者血清促卵泡激素（ＦＳＨ）、黄体生成素（ ... 详细信息

目的　研究抑郁症患者垂体促性腺激素及外周性激素的功能状态，探讨性激素水平改变与性有关症状和药物治疗的关系。方法　采用放射免疫法测定３０例（男１１例，女１９例）抑郁症患者血清促卵泡激素（ＦＳＨ）、黄体生成素（ＬＨ）、催乳素（ＰＲＬ）、睾丸酮（Ｔ）、雌二醇（Ｅ２）等激素水平，并与２０例（男女各１０例）正常人对照。结果　试验组男性ＬＨ和女性ＦＳＨ、ＲＰＬ明显高于对照组，其他性激素水平两组间无显著性差异。药物治疗前后男性患者ＰＲＬ、Ｔ、Ｅ２，女患者ＰＲＬ、Ｔ等激素分泌改变非常显著。结论　提示抑郁症患者性腺轴存在功能失调。性有关症状与性激素水平改变无关。抗抑郁治疗可导致性激素分泌紊乱。

目的观察长期苯妥英钠（ＤＰＨ）治疗对癫痫儿童牙齿生长发育的影响。方法把１８８例长期单服ＤＰＨ的患者按开始服的年龄分为乳牙组（Ａ组），换牙组（Ｂ组）及恒牙组（Ｃ组）。比较三组牙齿的色泽、排列、形状、乳牙滞留、恒牙萌出异常以及与齿龈增生的关系。结果三组牙异常发生率分别为３７２１％、３３３３％及８３３％，Ａ、Ｂ组明显高于Ｃ组；Ａ组较Ｂ组严重，但两组间无统计学意义的差异。１１例停药后随访３年以上，未见明显改善。结论换牙前接受ＤＰＨ治疗，牙的生长发育将会受到影响，并对牙齿带来难以逆转的影响，因此对儿童选用ＤＰＨ时应十分慎重。

第一届全国生物物理化学会议暨生物物理化学发展战略研讨会

＜正＞The MM-PB/SA method has been popular for computing protein-ligand binding free energies in recent *** previous evaluations of the MM-PB/SA method are based upon computer-generated conformational ensembles,which may be affected by the defective computational methods used for preparing these conformational *** an attempt to reach more convincing conclusions,we have evaluated the MM-PB/SA method on a set of 24 diverse protein-ligand complexes,each of which has a set of conformations derived from NMR *** results indicate that both MM-PB/SA and MM-GB/SA are able to produce a modest correlation between their results and the experimentally measured binding free energies on our test *** particular,both MM-PB/SA and MM-GB/SA produced better results by using a representative structure（R=0.72-0.79） than averaging over the conformational ensemble of each given complex（R=0.61-0.74）.A head-to-head comparison with four selected scoring functions（X-Score,PLP,ChemScore and DrugScore） on the same test set reveals that MM-PB/SA and MM-GB/SA results are marginally better than those produced by scoring funcitons,supporting the value of the MM-PB/SA ***, scoring functions are still more cost-effective options especially for high-throughput tasks.

AIM: To develop a cell assay system based on murine peritoneal macrophages for COX-1/COX-2 inhibitor screening and evaluate the inhibitory effect of Rofecoxib, Indomethacin and candidate compounds on COX-1 and COX-2 on the same cells. METHODS: Mouse peritoneal macrophages were induced by brewer thioglycollate medium. Macrophages were stimulated with calcimycin or lipopolysaccharide in different dose for various periods. Their abilities to convert endogenous arachidonic acid to its metabolite were examined. The 6-keto-PGF production in response to immediate
