目标:分析活动期葡萄膜炎患者在小梁切除术后的炎症反应及眼压情况。方法:我们回顾了2006-10/2011-03期间,接受了小梁切除术的活动期葡萄膜炎性青光眼患者纪录。手术前后的炎症反应、复发频率、类固醇依赖度及眼压均以配对t检验作比较。结果:在29例29眼患者中,90%的患眼在手术时正在接受局部类固醇治疗。患者平均年龄为58.3±14.0a,术前眼压为35.7±8.9mmHg。患者平均复诊时期为35.2±18.7mo。术后3mo前房炎症反应分级平均减少了0.4±0.6(P<0.01)。复发频率在复诊期内每年减少了2.3±2.1次(P<0.01)。术后1a的平均眼压为13.1±4.5mmHg,而其中44.8%患者的眼压无需用药亦能维持在21mmHg或以下。结论:小梁切除术后的葡萄膜炎性青光眼患者在炎症反应及眼压方面均有改善,但成功率较原发性青光眼患者低。小梁切除术可以作为活动期葡萄膜炎性青光眼患者早期控制眼压和炎症反应治疗的一个选择。

Clear cell hepatocellular carcinoma(CCHCC)has hitherto been considered an uncommon, highly differentiated variant of hepatocellular carcinoma(HCC) with a relatively favorable prognosis. CCHCC is composed of mixtures of clear and/or acidophilic ground glass hepatocytes with excessive glycogen and/or fat and shares histology, clinical features and etiology with common HCCs. Studies in animal models of chemical, hormonal and viral hepatocarcinogenesis and observations in patients with chronic liver diseases prone to develop HCC have shown that the majority of HCCs are preceded by, or associated with, focal or diffuse excessive storage of glycogen(glycogenosis) which later may be replaced by fat(lipidosis/steatosis). In ground glass cells, the glycogenosis is accompanied by proliferation of the smooth endoplasmic reticulum, which is closely related to glycogen particles and frequently harbors the hepatitis B surface antigen(HBs Ag).from the findings in animal models a sequence of changes has been established, commencing with preneoplastic glycogenotic liver lesions, often containing ground glass cells, and progressing to glycogen-poor neoplasms via various intermediate stages, including glycogenotic/lipidotic clear cell foci, clear cell hepatocellular adenomas(CCHCA) rich in glycogen and/or fat, and CCHCC. A similar process seems to take place in humans, with clear cells frequently persisting in CCHCC and steatohepatitic HCC, which presumably represent intermediate stages in the development rather than particular variants of HCC. During the progression of the preneoplastic lesions,the clear and ground glass cells transform into cells characteristic of common HCC. The sequential cellular changes are associated with metabolic aberrations, which start with an activation of the insulin signaling cascade resulting in preneoplastic hepatic glycogenosis. The molecular and metabolic changes underlying the glycogenosis/lipidosis are apparently responsible for the dramatic metabo

Ammonium uptake in plant roots is mediated by AMT/MEP/Rh-type ammonium transporters. Out of five AMTs being expressed in Arabidopsis roots, four AMT1-type transporters contribute to ammonium uptake, whereas no physiological function has so far been assigned to the only homolog belonging to the MEP subfamily, AMT2;1. Based on the observation that under ammonium supply, the transcript levels of AMT2;1 increased and its promoter activity shifted preferentially to the pericycle, we assessed the contribution of AMT2;1 to xylem loading. when exposed to ^15N-labeled ammonium, amt2;1 mutant lines translocated less tracer to the shoots and contained less ammonium in the xylem sap. Moreover, in an amtl;1 amtl;2 amtl ;3 amt2;1 quadruple mutant （qko）, co-expression of AMT2;1 with either AMT1;2 or AMT1;3 significantly enhanced ^15N translocation to shoots, indicating a cooperative action between AMT2;1 and AMT1 transporters. Under N deficiency, proAMT2;1-GfP lines showed enhanced promoter activity predominantly in cortical root cells, which coincided with elevated ammonium influx conferred by AMT2;1 at millimolar sub- strate concentrations. Our results indicate that in addition to contributing moderately to root uptake in the low-affinity range, AMT2;1 functions mainly in root-to-shoot translocation of ammonium, depending on its Cell-type-specific expression in response to the plant nutritional status and to local ammonium gradients.

药品和个人护理品(PPCPs)因其潜在的环境和健康风险受到了广泛关注。实验选取8种典型药品为对象,采用中试规模的活性炭工艺研究了其去除效果和影响因素。结果表明,活性炭工艺对安替比林、达舒平、舒必利、磺胺甲唑、泰妙菌素和氧苄胺嘧啶等的去除率为50%～90%,对林肯霉素和氨糖美辛的去除率均小于35%。典型药品的去除率受到滤速、有机物和pH等因素的影响,其中,氨糖美辛、林肯霉素和泰妙菌素等的去除率受滤速影响较大;磺胺甲唑的去除率受pH影响较大。有机物对典型药品去除率的影响既有促进作用,又有抑制作用。典型药品的物化性质对其去除行为有重要影响,这有利于从分子水平上认识活性炭工艺对典型药品的去除机理。
