ABSTRACT
Based on ZHU Zhenheng's “six constraints” theory， it is proposed that the formation of pulmonary nodules is closely related to the six constraints， which are constraint of qi， blood， phlegm， fire， dampness and food. All six constraints might lead to pulmonary nodules， among which qi constraint is the dominant one. When qi constraint lasts for a long time， it will turn into fire constraint， resulting in the failure of spleen to transport， which may lead to phlegm constraint， dampness constraint and food constraint； when qi fails to move blood， blood constraint is formulated. Mutual generation of six constraints lead to the disease， and the pathogenesis is interrelated， jointly promoting the occurrence and development of pulmonary nodules. The treatment is mainly to unblock qi， usually using Yueju Pills （越鞠丸）， a classic formula commonly used for six constraints， as the basic formula. And according to the six constraints partiality， it is suggested to flexibly add the medicinals of soothing the liver and rectifying qi， clearing heat and dissipating masses， dissolving phlegm and dissipating masses， fortifying spleen and dissipating dampness， promoting digestion and removing accumulation， invigorating blood and dissolving stasis.
ABSTRACT
Objective:To systematically evaluate the efficacy of epinephrine in preventing post-endoscopic retrograde cholangiopancreatography pancreatitis (PEP).Methods:Randomized controlled trials (RCTs) on epinephrine for preventing PEP from inception to October 10, 2020 were searched in databases including PubMed, Embase, The Cochrane Library, Web of Science, VIP Information Network, China National Knowledge Infrastructure,WanFang Data,and clinical trial registration platforms including ClinicalTrials.gov,WHO International Clinical Trial Registration Platform. Literature was screened independently by two reviewers, data were extracted and the risk of bias of included studies were assessed. The meta-analysis was performed by RevMan 5.3.Results:A total of 410 papers were retrieved and 8 RCTs involving 4 208 patients were included. The results of meta-analysis showed that compared with the saline group, the epinephrine could reduce the incidence of PEP ( RR=0.29,95% CI:0.16-0.50, P<0.001). There were no significant differences in the therapeutic effect between group epinephrine and group indomethacin ( RR=0.17,95% CI:0.02-1.39, P=0.100) or group indomethacin combined with epinephrine and group indomethacin ( RR=1.15,95% CI:0.61-2.16, P=0.670). Conclusion:Local spraying of epinephrine on the duodenal papilla can reduce the incidence of PEP compared with normal saline. But the epinephrine or combination of indomethacin and epinephrine fails to reveal any benefit over indomethacin alone in preventing PEP.
