Two novel diketopiperazines (1 and 5), along with ten known compounds (2-4, 6-12) demonstrating significant skin inflammation inhibition, were isolated from a marine-derived fungus identified as Aspergillus sp. FAZW0001. The structural elucidation and configurational reassessments of compounds 1-5 were established through comprehensive spectral analyses, with their absolute configurations determined via single crystal X-ray diffraction using Cu Kα radiation, Marfey's method, and comparison between experimental and calculated electronic circular dichroism (ECD) spectra. Compounds 1, 2, and 8 exhibited significant anti-inflammatory activities in Propionibacterium acnes (P. acnes)-induced human monocyte cell lines. Compound 8 demonstrated the ability to down-regulate interleukin-1β (IL-1β) expression by inhibiting Toll-like receptor 2 (TLR2) expression and modulating the activation of myeloid differentiation factor 88 (MyD88), mitogen-activated protein kinase (MAPK), and nuclear factor κB (NF-κB) signaling pathways, thus reducing the cellular inflammatory response induced by P. acnes. Additionally, compound 8 showed the capacity to suppress mitochondrial reactive oxygen species (ROS) production and nucleotide-binding oligomerization domain-like receptor protein 3 (NLRP3) inflammasome activation, thereby reducing IL-1β maturation and secretion. A three-dimensional quantitative structure-activity relationships (3D-QSAR) model was applied to compounds 5-12 to analyze their anti-inflammatory structure-activity relationships.

Objective To study the effect of modified periocular injection on the pains induced by local application of drugs. Methods Sixty patients treated with periocular injection were divided randomly into experimental group and control group in equal number. The control group was treated with orthodox periocular injection,while experimental group with modified periocular injection, immersing the pinhead into lidocaine solution before injection.The pain level of patients was evaluated by self-designed pain scale. Result The pain level of modified periocular injection was lower than that of orthodox periocular injection statistically (Z=3.799, P<0.001).Conclusion Modified periocular injection can alleviate pains induced of local application of drugs obviously and increase their compliance,so it deserves clinically popularizing.

OBJECTIVE:To evaluate the effect and safety of conservative treatment for treating cervical spondylotic radiculopathy by cochrane evaluation systems.DATA SOURCE:CBM(from January 1978 to October 2008),CNKI(from January 1978 to October 2008)and VIP(from January 1989 to October 2008)databases were retrieved by computer and partial documents were searched by hands.DATA SELECTION:Randomized controlled trial was adopted in course of acupuncture and moxibustion treatment for cervicel spondylotic radiculopathy and its quailty was assessed.Dafa source was randomized and semi-randomized controlled.Some evaluations such as random method-selection bias,allocation concealment-selection bias,blind method-performance bias and measurement bias,exclusion.lose to follow-up,withdraw-attrition bias were chosen.MAIN OUTCOME MEASURES:①Abdominal acupuncture needles were superior to the conventional method's efficiency.②Electro-acupuncture plus cupping with barbed floc were superior to the conventional method's efficiency.③Abdominal acupuncture were superior to traction's efficiency.④Cervical traction,electro-acupuncture combined with point injection and massage were superior to traction's efficiency.⑤Traction,electro-acupuncture,massage,TDP-guided were superior to traction,physiotherapy,TDP combined with exercise therepy's efficiency.⑥Vinegar iontophoresis and electro-acupuncture were superior to simple electro-acupuncture's efficiency.⑦Long's approach acupuncture was superior to simple acupuncture's efficiency.⑧Adverse reaction.RESULTS:A total of 1416 subjects were selected from 7 randomized controlled trials.All the studies have selection bias,measurement bias,loss of the high probability of bias,the quality and grade of"C"grade.And only one study proved that the efficiency of the experimental group was better than that of the control group.Study 1 showed that there was insufficient evidence suggested that acupuncture treatment of abdominal cervical spondylotic radiculopathy was efficient than conventional acupuncture.Study 2 showed that there was insufficient evidence suggested that electro-acupuncture plus cupping therapy with barbed floc was efficient than conventional acupuncture to cure cervical spondylotic radiculopathy.Study 3 showed that there was insufficient evidence suggested that acupuncture treatment of abdominal cervical spondylotic rediculopathy was efficient than traction.Study 4 showed that the cervical traction,electro-acupuncture combined with acupoint-injection treatment of cervical spondylotic radiculopathy was efficient than traction combined massage therapy.Study 5 showed that there was insufficient evidence suggested that traction,electro-acupuncture,massage,TDP-guided therapy was efficient than traction,physical therapy,TDP combined with exercise therapy.Study 6 showed that there was insufficient evidence suggested thatelectro-acupuncture combined with vinegar iontophoresis treatment of cervical spondylotic radiculopathy was better than the simple electro-acupuncture therapy.Study 7 showed that there was insufficient evidence suggested that the acupuncture therapy using Long's approach was better than simple acupuncture.No adveme reactions appeared to terminate the test in 7 studies.CONCLUSlON:The above seven studies mainly present with low quality,absence of a unified curative method,small samples,difference of follow-up time,iudgment standard and measurement standard.So more samples,multicenter and more regular randomized controlled trial should be performed.

目的观察分期综合疗法治疗颈椎间盘突出症的疗效。方法将100例颈椎间盘突出症住院患者随机分为治疗组(采用分期综合疗法)与对照组(采用传统综合疗法)各50例,评定两组患者的疗效。结果治疗组总有效率88%,对照组总有效率78%,两组间有显著性差异(P<0.05)。结论分期综合疗法治疗颈椎间盘突出症的疗效优于传统综合疗法。
