Methods:(1) Dissoluble PGN and CpG DNA were immobilized onto the surface of biotin cuvette for establishing target. Another effective tracking approach was established by immobilizing Escherichia lipid A F583 onto the surface of Non-derivatised cuvett. The biosensor technology was applied to screen anti-inflammatory TCM targeting on three key molecules.(2) The active compositions were isolated by AB-8 macroreticular resin from lycium bark. After the activities of compositions were evaluated, the most effective compositions was confirmed. In vitro, the affinities of different concentrations composition E binding with PGN, CpG DNA and lipid A were measured separately. The effect of composition E on vigor of RAW264.7 cells were tested by MTT and CCK-8, and its inhibition on TNF-α, which was released from RAW264.7 cells induced by PGN, CpG DNA and LPS, was also tested by ELISA. In vivo, murine sepsis models were made by intravenously heat-killed E.coli and heat-killed S.aureus, then protection of composition E on mice sepsis model were observed.

In the first part, study 1 was designed to investigate the development of the science inquiry ability in the group of the primary and secondary School student, and how the task difficulty affects science inquiry. We used the self-directed, computer simulated inquiry task, namely pendulum and string task It required the subjects to find the factors that affected the swing frequency of the pendulum and the level of stretch of the string. To evaluate the ability of science inquiry, we analyzed subjects'experiment-design strategies, evidence-evaluation strategies, and results of inference.

"Interstitial cystitis may be a common unrecognized cause of pelvic pain in gynecologic patients and deserves greater, if not primary, consideration in the differential diagnosis of pelvic pain," the authors write."If IC goes unrecognized, the pain may become intractable because of altered pain pathways, or IC may reach advanced stages, when substantial damage to the bladder has occurred."Am J Obstet Gynecol. Reviewed by Gary D. Vogin, MD
间质性膀胱炎可能是造成妇科患者骨盆疼痛的常见原因,却不易被诊断出来,然而若真的罹患这个疾病却未被诊断出来,一旦膀胱发生实质的伤害,那麼将会变得难以治疗,因为造成疼痛的病理机转可能已经改变,或间质性膀胱炎的病情已经恶化,因此采用其他不同方法来协助间质性膀胱炎的诊断是很重要的。
