ObjectiveTo investigate the effect of Yuejuwan on lipid metabolism in serum， prefrontal cortex and hippocampus of depressed mice based on lipidomics， and to explore the potential pathways for improving lipid metabolism to prevent depression. MethodsSeven-week-old C57BL/6 mice were randomly divided into blank group， model group， Yuejuwan group（3.6 g·kg^-1） and fluoxetine group（10 mg·kg^-1）， and chronic unpredictable mild stress（CUMS） was used to establish the depression model. After 3 weeks of modeling， each administration group was gavaged with the corresponding drug solution according to the dose， and mice in the blank and model groups were given an equal volume of deionised water by gavage， one time/d for 2 weeks. After administration， the antidepressant effect of Yuejuwan was evaluated by neurobehavioral indices such as sucrose preference test， open field test， tail suspension test and forced swimming test. An automatic biochemical analyzer was used to measure contents of total cholesterol（TC）， triglyceride（TG）， low-density lipoprotein cholesterol（LDL-C）， high-density lipoprotein cholesterol（HDL-C）， aspartate aminotransferase（AST） and alanine aminotransferase（ALT） in mouse serum. Lipidomic analysis of mouse serum， prefrontal cortex and hippocampus was performed based on ultra-performance liquid chromatography-linear ion trap-electrostatic field orbitrap mass spectrometry（UPLC-LTQ-Orbitrap-MS）， and the expression of mammalian target of rapamycin（mTOR）， ribosomal protein S6 kinase（S6K）， phosphorylation（p）-mTOR， p-S6K in gastric tissues of mice was detected by Western blot. ResultsCompared with the blank group， mice in the model group exhibited significantly reduced sucrose preference rate and center movement time in the open field test（P<0.01）， the immobility times in the tail suspension test and forced swimming test were significantly increased（P<0.01）， and serum levels of TC， TG， LDL-C， HDL-C， AST and ALT were significantly elevated（P<0.05， P<0.01）. Compared with the model group， the Yuejuwan group showed a significant increase in the sucrose preference rate and center movement time in the open field test（P<0.01）， the immobility times in the tail suspension test and forced swimming test were significantly reduced（P<0.01）， and the serum levels of TC， TG， LDL-C， AST and ALT were significantly decreased（P<0.05， P<0.01）. Lipidomic analysis revealed that Yuejuwan had a significant effect on lipid metabolism in serum， prefrontal cortex and hippocampus of depressed mice， and The differential lipid metabolites were mainly enriched in the metabolic pathways of glycerophospholipid metabolism， sphingolipid signaling， and glycosylphosphatidylinositol-anchored protein biosynthesis， among which the glycerophospholipid metabolic pathway was the most significant. Western blot results showed that compared with the blank group， the relative expression levels of p-mTOR/mTOR and p-S6K/S6K in the gastric tissues of mice in the model group were significantly increased（P<0.01）. In comparison with the model group， the relative expression levels of p-mTOR/mTOR and p-S6K/S6K in the gastric tissues of mice in the Yuejuwan group were significantly decreased（P<0.01）. ConclusionThe intervention of Yuejuwan on lipid metabolism is one of the potential pathways for its antidepressant effect， which may be related to the regulation of mTOR/S6K signaling pathway upstream of lipid metabolism in the gastric tissues.

The irrational use of Chinese patent medicines （CPM） is becoming more and more prominent， which makes the demand for clinical practice guidelines of CPM gradually increase. In order to make domestic scholars understand the latest developments and existing problems of the CPM guidelines， and promote its development， this paper introduced the concept of CPM guidelines， summarized the characteristics of the two development modes， namely “taking CPM as the key” and “taking disease/syndrome as the key”， and analyzed the current methodological status of developing and reporting CPM guidelines. Based on the existed problems， three suggestions have been put forward to optimize the quality of CPM guidelines， which were clarifying the target users and scope of CPM guidelines， establishing an open and transparent mechanism of the personnel involvement and process steps， and formulating implementable and operable recommendations for the use of CPM.

This paper summarized the key points and methods in terms of the establishment of the guideline working group and the management of conflict of interests， trying to provide reference for the development of clinical practice guidelines for Chinese patent medicine （CPM）. The establishment of the working group is the first important step for developing CPM guidelines. Considering the characteristics of the clinical practice guidelines for CPM， this study suggests that the three key elements of ‘multidisciplinarity’， ‘clinical relevance’ and ‘geographical representativeness’ should be put focus on when forming the working group. The guideline advisory committee， clinical expert group， evidence systematic evaluation group， secretary group and the external review group should be established. All group members should clarify the conflict of interest， and the process and management method of the conflict of interest should be clearly reported.

Especially， it details the items related to the rules and regulations of the use of CPMs in the recommendations， which is helpful for improving the completeness， scientificity and practicality of the reporting of CPMs guideline.

Objective To screen the active components of total flavonoid extracts of Sarcandra glabra to promote megakaryocyte differentiation.Methods(1)A model of megakaryocyte differentiation disorder was established by co-culturing human megakaryocytic leukaemia cells(Dami)with human bone marrow stromal cells(HS-5)as an evaluation system,and the experimental groupings were as follows:the Dami group(Dami),the control group(Dami+HS-5),and the PMA group[Dami+HS-5+5 ng·mL-1 foprolol 12-tetradecanoate 13-acetate(PMA)],and model group[Dami+HS-5+1%rabbit anti-rat platelet serum(APS)+5 ng·mL-1 PMA]were cultured for 48 hours.The expressions of megakaryocyte differentiation and maturation surface marker molecules,CD41a and CD61 were detected by flow cytometry.(2)Forty-nine SD male rats were randomly divided into blank plasma group,15-minute group,30-minute group,60-minute group,90-minute group,120-minute group,and 240-minute group,with 7 rats in each group.The rats in each administration group were gavaged with 1.26 g·kg-1 of total flavonoids extracts of Sarcandra glabra,and blood was collected at six set time points(15,30,60,90,120,240 minutes)for the preparation of time-dependent serum-containing plasma of total flavonoids extracts of Sarcandra glabra.(3)Ultra-high performance liquid chromatography-quadrupole tandem time-of-flight mass spectrometry(UHPLC-Q-TOF/MS)was used to analyze the plasma of the time-dependent serum-containing plasma of the total flavonoids extracts of Sarcandra glabra,and the peak area was used to construct a matrix(X-matrix)of the amount of chemical composition change over time in the time-dependent serum-containing plasma of the total flavonoids extracts of Sarcandra glabra.The collected time-dependent serum-containing plasma of the total flavonoids extracts of Sarcandra glabra at six different time points was used to intervene in the model of megakaryocyte differentiation and maturation disorder,and the expression of cell surface molecules CD41a and CD61 was detected by flow cytometry to construct the matrix of effect of time-dependent serum-containing plasma of the total flavonoids extracts of Sarcandra glabra(Y-matrix).(4)After the data of X and Y matrices were standardized,partial least squares(PLS)was used to calculate and analyze the quantitative and qualitative effect relationship,and variable importance for projection(VIP)>1 was used as the threshold to screen the effect components related to the changes of cell surface molecules CD41a and CD61,and chemical composition identification,as the potential effector components in the total flavonoid extracts of Sarcandra glabra were used to promote the differentiation of megakaryocytes,and finally the regression evaluation system was used to verify the efficacy of its medicinal effect.Results(1)Compared with the Dami group,the expression level of CD41a on the surface of Dami cells in the control group was significantly increased(P＜0.05).Compared with the control group,the expression levels of CD41a and CD61 on the surface of Dami cells in the PMA group were significantly increased(P＜0.01).Compared with the PMA group,the expression levels of CD41a and CD61 on the surface of Dami cells in the model group were significantly reduced(P＜0.01).(2)Compared with the blank plasma group,the expression levels of the molecules CD41a and CD61 on the surface of Dami cells at each time point of 15,30,60,90,120,and 240 minutes were significantly increased(P＜0.01),and the expression levels of CD41a and CD61 were both highest in the 30-minute group.The potential effective components with VIP value greater than 1 were screened out in the positive and negative ion mode,and 540.3638@12.25 and 559.2991@11.53 were selected for pharmacodynamic verification.559.2991@11.53 was identified as daucosterol(Dau),540.3638@12.25 was identified as rosmarinic acid 4-O-β-D-glucoside(Ros).After Ros and Dau intervened in the megakaryocyte differentiation and maturation disorder model respectively,the expression levels of CD41a and CD61 on the surface of Dami cells in the low-,medium-and high-dose groups(40,60 and 80 μg·mL-1)of Ros and Dau were significantly increased compared with the model group(P＜0.05,P＜0.01).Conclusion Ros and Dau may be the active components of the total flavonoids extracts of Sarcandra glabra to promote the differentiation of megakaryocytes.

The lack of direct evidence is an important problem faced in the formation of recommendations in rapid living guidelines of traditional Chinese medicine under public health emergencies， and the supplementation of indirect evidence can be a key method to solve this problem. For the collection of evidence， the type of evidence required， including direct and indirect evidence， should be clarified， and ‘direct first’ principle for selecting evidence can be set to standardize and accelerate the guideline development. When integrating evidence， recommendations can be formed directly if there is sufficient direct evidence， while regarding insufficient direct evidence， recommendations need to be supplemented and improved by integrating indirect evidence. In addition， when the body of evidence contains evidence from multiple sources， it is suggested to rate the evidence according to “higher rather than lower” principle. Finally， when forming recommendations， the level of evidence， safety and economic efficiency should be taken into consideration to determine the strength of the recommendation.

In developing rapid and living guidelines of traditional Chinese medicine （TCM） in response to public health emergencies， it is important that evidence continue to be reviewed， and clinical questions and recommendations updated if necessary， due to the rapid changes in disease progression and the continuous generation of relevant research evidence. This paper proposed that the updating scope in dynamic mode should first be identified； then evidence monitoring should be carried out in four aspects， including clinical research， related guidelines or laws and regulations， disease progression， as well as clinical use of recommendations and clinical needs； finally， based on the results of the evidence monitoring， different options should be made， including revising the clinical questions， updating the evidence and recommendations， and withdrawing the guideline.
