基于经方解构新说“石膏配伍解肌法”

石膏解肌之说由来已久,但限于矿物药的溶出及研究手段有限等现实问题,其临床推广及应用不足,深入探讨亦不足。该文通过梳理解肌法的脉络,总结出解肌法所针对的病机为“津液不足,兼表不和”,而石膏解肌的核心内涵为“清火存液,兼透表邪”;通过梳理解肌法的古今运用,结合配位化学的现代研究,从配伍角度入手,主以《伤寒论》和《金匮要略》中的经方为例,拓展了石膏解肌之内涵,总结出石膏的解肌作用不仅可以治疗外感后的肌肉不适症状,还可能影响脏腑功能,进而治疗内伤杂病,并由此提出“石膏配伍解肌法”,认为石膏与麻黄、葛根、防己、知母、人参、芍药、竹茹、生地黄、麦冬和葳蕤等药物配伍后,通过调整透散和清热的力度来更好地发挥解肌作用。该文附临床验案一则予以阐发,以期为石膏的临床运用提供参考,为其配伍使用的药物机制研究提供方向。

睫状神经营养因子对应激大鼠体质量的影响及其机制探讨

①目的　探讨睫状神经营养因子 (CNTF)对躯体性和心理性应激大鼠体质量的影响及其与下丘脑促肾上腺皮质素释放激素 (CRH)含量的关系。②方法　建立应激大鼠动物模型 ,应用鼠脑立体定向方法 ,在应激前给予大鼠双侧海马微量注射CNTF ,称量大鼠应激前后的体质量变化 ,并用放射免疫分析法测定大鼠下丘脑CRH含量的变化。③结果　在应激前及应激期间给予双侧海马微量注射CNTF ,可以有效改善应激引起的大鼠体质量的下降 (t=2 .16 3.86 ,P <0 .0 5 ,0 .0 1) ,改善应激引起的下丘脑CRH含量的升高 (t=3.0 5 4.0 3,P <0 .0 1)。④结论　CNTF可以改善应激对大鼠生长的损害 ,其机制可能与CNTF降低应激大鼠下丘脑CRH的含量有关。     

Intra-articular infiltration analgesia for arthroscopic shoulder surgery: a systematic review and meta-analysis

Phrenic-sparing analgesic techniques for shoulder surgery are desirable. Intra-articular infiltration analgesia is one promising phrenic-sparing modality, but its role remains unclear because of conflicting evidence of analgesic efficacy and theoretical concerns regarding chondrotoxicity. This systematic review and meta-analysis evaluated the benefits and risks of intra-articular infiltration in arthroscopic shoulder surgery compared with systemic analgesia or interscalene brachial plexus block. We sought randomised controlled trials comparing intra-articular infiltration with interscalene brachial plexus block or systemic analgesia (control). Cumulative 24-h postoperative oral morphine equivalent consumption was designated as the primary outcome. Secondary outcomes included visual analogue scale pain scores during the first 24 h postoperatively; time-to-first analgesic request; patient satisfaction; opioid-related side-effects; block-related adverse events; and any indicators of chondrotoxicity. Fifteen trials (863 patients) were included. Compared with control, intra-articular infiltration reduced 24-h postoperative analgesic consumption by a weighted mean difference (95%CI) of −30.9 ([−38.9 to −22.9]; p < 0.001). Intra-articular infiltration also reduced the weighted mean difference (95%CI) pain scores up to 12 h postoperatively, with the greatest reduction at 4 h (−2.2 cm [(−4.4 to −0.04]); p < 0.05). Compared with interscalene brachial plexus block, there was no difference in opioid consumption, but patients receiving interscalene brachial plexus block had better pain scores at 2, 4 and 24 h postoperatively. There was no difference in opioid- or block-related adverse events, and none of the trials reported chondrotoxic effects. Compared with systemic analgesia, intra-articular infiltration provides superior pain control, reduces opioid consumption and enhances patient satisfaction, but it may be inferior to interscalene brachial plexus block patients having arthroscopic shoulder surgery.     

卵巢子宫内膜异位症相关不孕年轻女性患者术后应用GnRH-a对自然受孕率的影响

目的观察腹腔镜手术后应用促性腺激素释放激素激动剂(Gn RH-a)对卵巢子宫内膜异位症(OEM)相关不孕的治疗效果,为临床应用提供依据。方法回顾性分析2013年1月-2017年12月于盘锦市中心医院接受保守性腹腔镜手术治疗的83例OEM伴不孕患者的临床资料。其中,37例患者单纯接受手术治疗,记为对照组;46例患者术后接受Gn RH-a治疗,记为观察组。对比两组月经周期与月经量恢复正常的时间、盆腔痛与痛经的视觉模拟评分法(VAS)评分、性激素[黄体生成素(LH)、雌二醇(E2)、卵泡刺激素(FSH)]水平、自然受孕率,并分析观察组给药期间的不良反应发生率。结果观察组月经周期与月经量的恢复时间均短于对照组,差异有统计学意义(P<0.05);治疗后,观察组盆腔痛、痛经的VAS评分低于对照组,差异有统计学意义(P<0.05);治疗后,观察组LH、E2、FSH水平低于对照组,差异有统计学意义(P<0.05);给药期间,观察组不良反应发生率为8.70%;随访期间,观察组自然受孕率高于对照组,差异有统计学意义(P<0.05)。结论腹腔镜手术后应用Gn RH-a对OEM相关不孕的治疗效果确切,可促进患者月经恢复正常,改善盆腔痛、痛经症状与性激素水平,提高患者自然受孕率,且安全性较高。     

The role of protein kinase C and its effect on GHRH in the regulation of hormone secretion by somatotrophinomas

In recent years, the most exciting advance inthe research of human pitllitary tumors is the discovery that 30 %--40 % of hfuman pituitary somatotrophinomas carry somatic missense single--basemutations within codons 201 and 227 of the genefor the a--subunit of the stimulatory GTP--bindingprotein, Gs (Gsa). These mutations, termed gsponcogenes, result in constitutive activity of adenylyl cyclase and the subsequent elevations in intracellular cAMP levels are thought to be responsiblefor tumor g…
