桂枝茯苓丸联合妇乐片对子宫内膜异位症的临床疗效

目的:探讨桂枝茯苓丸联合妇乐片对子宫内膜异位症患者血清甲胎蛋白(AFP)、血清脂质结合唾液酸(LSA)及临床疗效的影响。方法:选取我院确诊并治疗的子宫内膜异位症患者68例,按随机数字表法进行分组,每组34例。对照组患者予以妇乐片口服治疗;研究组患者在对照组用药基础上予以桂枝茯苓丸联合治疗,所有患者连续服药6个月。观察两组患者治疗前后血清甲胎蛋白(AFP)、血清LSA、肿瘤坏死因子-α(TNF-α)及血管内皮生长因子(VEGF)水平的变化情况、临床疗效及不良反应发生率。结果:研究组治疗后临床有效率91.18%,高于对照组治疗后临床有效率70.59%,差异具有统计学意义(P0.05);与对照组比较,研究组治疗后血清AFP、LSA、TNF-α、VEGF水平降低,差异具有统计学意义(P0.05);对照组不良反应发生率为8.24%,研究组不良反应发生率为5.88%,两组间不良反应发生率无统计学意义(P0.05)。结论:采用桂枝茯苓丸联合妇乐片治疗子宫内膜异位症,能有效提高患者的临床疗效,推测其机制与降低血清AFP、LSA、TNF-α、VEGF水平有关。     

Manually and automatically produced pellet cultures of human primary chondrocytes: A comparative analysis

Cartilage defects are often associated with restriction of the locomotor system. New methods are required to investigate cartilage tissue and for the repair of cartilage tissue. 3D cultures are promising due to better simulation of in vivo conditions. The aim of this study was to provide a model system for studying cartilage tissue. We solved this problem by automated production of pellet cultures of human primary chondrocytes in media with and without antibiotics using the Biomek® Cell Workstation and consequent automated bioscreening with a high‐throughput screening system, and compared with the regular manual processes. The Biomek® Cell Workstation allows the cultivation of different cell types (suspensions cells and adherent cells) and 3D cell cultures (pellet cultures, alginate beads and spheroid cultures). The proliferation was analyzed by DNA quantification and compared with the EZ4U proliferation assay as a new tool for pellet cultures. The toxicity was evaluated by the detection of ubiquitous adenylate kinases. The proliferation increased from day 14 until day 35 and was associated with a decrease in the cytotoxicity. The comparative analysis showed similar results for manual and automated processes. We concluded that the manual methods can be replaced by automated processes (pellet manufacturing and screening), which would allow large‐scale procedures to support studies on cartilage regeneration.     

桂枝茯苓胶囊对卵巢囊肿患者囊肿核摘除术后血清雌激素、AMH及LSA水平的影响

目的:探究桂枝茯苓胶囊对卵巢囊肿患者囊肿核摘除术后血清雌激素、抗苗勒氏管激素(AMH)及脂质结合唾液酸(LSA)水平的影响。方法:选择我院收治的已行囊肿核摘除术的卵巢囊肿患者39例,将其随机分为实验组及对照组。对照组18例予甲硝唑联合青霉素注射治疗;实验组21例予桂枝茯苓胶囊治疗。治疗后,对比两组的临床疗效及治疗前后血清雌激素、AMH及LSA的水平。结果:治疗后,实验组总有效率(95.2%)显著高于对照组(72.2%),差异具有统计学意义(P0.05);治疗后,两组血清雌激素、AMH水平均明显升高,血清LSA水平显著降低,差异均具有统计学意义(P0.05);与对照组比较,实验组治疗后血清雌激素、AMH较高,而LSA水平较低,差异具有统计学意义(P0.05)。结论:桂枝茯苓胶囊可以有效提高行囊肿核摘除术卵巢囊肿患者的临床疗效,这可能与其提高血清雌激素及AMH水平并降低血清LSA水平有关。     

Border Cave revisited: a revised ESR chronology

In view of a decade of progress in ESR dating we have revised the ESR chronology of Border Cave. A detailed gamma ray survey in 1994 and newly calculated beta attenuation data led to total dose rate estimations that are between 0 and 30% smaller than previously estimated. Accordingly, the resulting ESR age estimates are between 0 and 30% older. The ESR dates are now in good agreement with independent age estimates, particularly(14)C and amino acid racemization. New ESR dates for the lowermost dated sedimentary layer, 5 WA (white ash), indicate that the sedimentation of the sequence started around 200 ka ago.
