To determine the optimum conditions of supercritical CO2 extraction of Xiaoyaosan, and establish its fingerprint by gas chromatography-mass spectrometry (GC-MS), the yield of extract were investigated, an orthogonal test was used to quantify the effects of extraction temperature, pressure, CO2 flow rate and time, and fingerprint analysis of different batches of extracts were by GC-MS. The optimal extraction conditions were determined as follows: extraction pressure 20 MPa, extraction temperature 50 degrees C, CO2 flow rate 25 kg x h(-1), extraction time 3 h, and average yield 2.2%. The GC-MS fingerprint was established and 27 common peaks were found, whose contents add up to 81.89% of the total peak area. Among them, 21 compounds were identified, accounting for 53.20% of the total extract. The extraction process is reasonable and favorable for industrial production. The GC-MS method is accurate, reliable, reproducible, and can be used for quality control of supercritical CO2 extract from Xiaoyaosan.

Objective To investigate the effect of extracorporeal membrane oxygenation (ECMO) combined with ultrafiltration in treatment of kidney injury induced by serious hemorrhagic shock in rabbits.Methods Models of pressure-controlled hemorrhagic shock was developed in 24 New Zealand white rabbits which were divided into unresuscitation group (n =8),ECMO combined with ultrafiltration group (combined resuscitation group,n =8),and fluid resuscitation group (n =8) according to the random number table.Heart rate was monitored via electrocardiograph and arterial pressure via fermoral artery catheter.Blood samples were collected pre-and post-shock and after resuscitation to measure levels of lactic acid,serum creatinine,IL-6,and TNF-α.Kidney samples were collected for measurement of histopathological changes via HE staining,expression of heat shock protein 70 (HSP70) via immunohistochemical staining.Results Arterial pressure was (53.1 ± 11.4) mmHg in combined resuscitation group,higher than (41.3 ± 11.1) mmHg in fluid resuscitation group and (25.9 ± 10.5) mmHg in unresuscitation group (F =41.425,P ＜ 0.05).Hemorrhagic shock induced significant up-regulation of lactic acid,serum creatinine,IL-6,and TNF-α(P ＜ 0.05),but all were lowered after resuscitation,especially in combined resuscitation group (P ＜ 0.05).HE staining showed the degree of kidney tissue necrosis and inflammatory cytokine infiltration in combined resuscitation group alleviated notably compared with fluid resuscitation group.Median and interquartile values of HSP70 were 17 828.960 0 (15 779.865 0-21 751.980 0) in unresuscitation group,2 714.270 0 (1 339.215 0-7 616.950 0) in fluid resuscitation group,and 262.930 0 (198.820 0-538.195 0) in combine resuscitation group,with statistical differences among groups(P ＜ 0.05).Conclusion ECMO combined with ultrafiltration is superior to conventional fluid resuscitation in improving hypoxia tissue injury and inflammatory reaction after hemorrhagic shock and is beneficial to attenuating kidney injury.

The tail suspension test (TST), forced swimming test (FST) and chronic unpredictable mild stress (CUMS) model were used to evaluate the anti-depressant effect of supercritical CO2 extract from Compound Chaigui Fang (FFCGF). A nuclear magnetic resonance (NMR)-based metabonomics combined with multivariate statistical analysis was performed to explore the mechanism of FFCGF. Rats were conducted by CUMS procedure for 28 days and drugs were administrated at the same time. The body weight, sucrose preference, crossings and rearings in open-field tests were evaluated and the urine was collected simultaneously. The metabonomic profiles of rats' urine were analyzed by NMR and potential biomarkers were searched by multivariate statistical analysis. The results showed that administration of FFCGF significantly decreasing the immobility time in FST and TST and improving rats' body weight, sucrose preference, crossings and rearings in CUMS, which were indication that the anti-depressant effect of FFCGF was abvious. Significant differences in the metabolic profile of the CUMS treated group and the control group were observed, which were consistent with the results of behavioral tests. Decreased levels of acetic acid, succinic acid, 2-oxidation glutaric acid and citric acid and increased glycine and pyruvic acid in urine were significantly affected by the CUMS procedure and the 6 biomarkers were reversed evidently after administration of FFCGF. These changes were suggestion that the anti-depressant mechanism of FFCGF was associated with energy metabolism, lipid metabolism and amino acid metabolism.
