Résumé
Compound formulas of traditional Chinese medicines (TCM), also known as prescription in clinic, refers to a form of medication in which several TCMs are selectively combined according to the certain compatibility principles and the needs of patient’s condition, based on syndrome differentiation and treatment. At present, the methods and strategies for investigating the compatibility mechanisms of TCM prescriptions mainly focus on the following two aspects: analysis of pharmacological substances (including chemical composition analysis of TCM, ingredients of TCM analysis in blood, and pharmacokinetic analysis) and pharmacological signaling pathways analysis (involving network pharmacology analysis, signal pathway indicator detection, and metabolomics analysis). In future research, the compatibility relationships of TCM prescriptions should be explored according to the principles of “Qiqing Hehe”,“ Shengjiang Fuchen”,“ Junchen Zuoshi”, and “Siqi Wuwei”. The regularity of TCM prescriptions compatibility should be shown in the change regularity of chemical components, pharmacokinetics, pharmacological pathways, and chemical compositions of various ratios of TCMs. Based on the insurance of holistic efficacy of TCM prescriptions, the underlying mechanisms of compatibility should be uncovered, which will provide references for the optimization of clinical applications of prescriptions and new directions for the creation of innovative TCM prescriptions.

Objective To investigate the effects of different dosages of bone marrow mesenchymal stromal cells (BMSC) on lung fibrosis. Methods BMSCs with red fluorescence protein (RFP) from male FVB mice were cultured in vitro. Twenty-four female wild type FVB mice were randomly divided into four groups: normal group, model group, BMSC 1 group and BMSC 2 group (n = 6). Mouse pulmonary fibrosis models were induced by bleomycin via single intratracheal perfusion. Twenty-four h after model establishment, mice in BMSC 1 group and BMSC 2 group were injected with 1 × 10~6 BMSCs and 2 × 10~6 BMSCs, respectively through vena caudalis for each mouse. All the animals were sacrificed 21 d after model estalishment, and mouse lung tissue samples were obtained. The pathological changes were observed by light microscopy, the hydroxyproline ( Hyp) contents were measured by alkaline hydrolysis assay, the distribution of RFP( + ) BMSCs and quantitation of RFP were analysed by laser scanning confocal microscopy and immunohistochemistry, the expression of surfactant protein A (SP-A) was detected by immunohistochemistry, and the expression of transforming growth factor-β (TGF-β) and platelet-derived growth factor (PDGF) mRNA was detected by Real-time PCR. Results Compared with model group, the pulmonary fibrosis in BMSC 1 group was significantly alleviated, and that of BMSC 2 group became much more severe.A large number of RFP( +) BMSCs were found in fibrosis area of BMSC 2 group,which exhibited morphology similar to fibroblasts. As far as the expression of SP-A was concerned, normal group was higher than BMSC 1 group, BMSC 1 group was higher than BMSC 2 group and model group (P < 0. 05), while there was no significant difference between BMSC 2 group and model group (P >0. 05). Normal group, BMSC I group, model group and BMSC 2 group fell in the increase order by Hyp contents (P <0.01, P <0.05), and BMSC 2 group, BMSC 1 group, model group and normal group fell in the decrease order by expression of TCF-|$ and PDGF mRNA (P < 0.05). Conclusion Proper dose of BMSC has a favourable effect on bleomycin-induced lung fibrosis, while excessive dose of BMSC can aggravate the fibrosis.

Objective To observe the dynamic changes of adrenomedulin(ADM) and calcitonin-gene-relat-ed peptide(CGRP) at different time before,during and after laparoscopic operation for treating CO2 pneumoperitone-urn. Methods 47 cases undergoing laparoscopic operation in our hospital were selected. Plasma ADM and CGRP levels were determined by RIA before anesthesia(T0),10 min before (T1) and 10 min (T2) ,30 min (T3),60 min (T4),and 30 min (TS) after CO2 pneumoperitoneum was treated. Results There was statistical significance in ADM and CGRP level at the different time points before and after CO2 pneumoperitoneum (F=9.686 and 49.804, P<0.01). There was no significance in ADM and CGRP level at TO and T1 (P>0.05);ADM level would decrease at T2 (P<0.05) but CGRP level decrease slowly with no remarkable change as compared with that before CO2 pneumoperitoneum(P>0.05). With time going on, ADM and CGRP level at T3 and T4 was remarkably lower than that at T1 (P<0.01);ADM and CGRP level at T5 would come to that at T1. Conclusions CO2 pneumoperitoneum during laparoscopic operation is the major factor causing decreased ADM and CGRP level;The decrease of ADM and CGRP level will influence the cardiac endocrine function,so CO2 pneumoperitoneum operation should be taken seri-ously when the patients have heart disease and cryptorrhea.
