ABSTRACT
Objective:To investigate the diagnostic value of independent and combined subtests of the psychometric hepatic encephalopathy score (PHES) in mild hepatic encephalopathy(MHE) of patients with liver cirrhosis, so as to optimize the PHES.Methods:This was a prospective, multicenter and real-world study which was sponsored by the National Clinical Research Center of Infectious Diseases and the Portal Hypertension Consortium. Twenty-six hospitals from 13 provinces, autonomous regions and municipalities countrywide participated in this study, induding Tianjin Third Central Hospital, the Fourth People′s Hospital of Qinghai Province, the Second Affiliated Hospital of Baotou Medical College, the Third People′s Hospital of Taiyuan, the Fifth Medical Center of PLA General Hospital and so on. From October 2021 to February 2022, outpatients and hospitalized patients with liver cirrhosis and no obvious hepatic encephalopathy were consecutively enrolled. All patients received 5 PHES subjects in the same order: number connection test(NCT)-A, NCT-B, digit symbol test(DST), line tracing test(LTT) and serial dotting test(SDT), and the scores were calculated. The total score of PHES <-4 was taken as the cut-off value for diagnosing MHE. Compare the differences in each subtest between MHE group and non-MHE group. Receiver operating characteristic curve(ROC) and area under the curve(AUC) was performed to assess the diagnostic value of independent and combined subtests in MHE. Mann-Whitney U test and DeLong test were used for statistical analysis. Results:A total of 581 patients with liver cirrhosis were enrolled, 457 were diagnosed as MHE, and the incidence of MHE was 78.7%. The results of NCT-A, NCT-B, SDT, LTT, DST of MHE group were 60.00 s(47.01 s, 88.00 s), 90.45 s(69.32 s, 125.35 s), 74.00 s(57.65 s, 96.60 s), 74.72(60.00, 98.61) and 27.00(20.00, 36.00), respectively. Compared those of non-MHE group(34.00 s(29.15 s, 44.48 s), 50.00 s(40.98 s, 60.77 s), 50.00 s(41.07 s, 63.03 s), 46.23(38.55, 59.42) and 42.00(34.00, 50.75)), the differences were statistically significant( Z=12.37, 12.98, 9.83, 11.56, 10.66; all P<0.001). The AUC(95% confidence interval(95% CI)) of subtests of PHES NCT-B, NCT-A, LTT, DST and SDT alone in MHE diagnosis were 0.880(0.849 to 0.910), 0.862(0.828 to 0.896), 0.838(0.799 to 0.877), 0.812(0.772 to 0.851) and 0.788(0.743 to 0.832), respectively. The combination of 2 PHES subtests significantly increased the diagnostic efficacy. Among them the diagnostic efficacy of the combination of NCT-B and LTT was the best, the AUC(95% CI) was 0.924(0.902 to 0.947), the specificity was 91.9% and the sensitivity was 79.2%, which was better than a single PHES subtest (NCT-A, NCT-B, SDT, LTT and DST) and the combination of NCT-A and DST(AUC was 0.879, 95% CI0.847 to 0.910) which was recommended by guidelines on the management of hepatic encephalopathy in cirrhosis, the differences were statistically significant ( Z=3.78, 3.83, 5.57, 5.51, 5.38, 2.93; all P<0.01). Furthermore, compared between the combination of NCT-B and LTT and the combination of 3 subests of PHES, only the diagnostic efficacy of combination of NCT-B, LTT and SDT (AUC was 0.936, 95% CI 0.916 to 0.956) was better than that of the combination of NCT-B and LTT, the difference was statistically significant( Z=2.32, P=0.020). Conclusion:Based on the diagnostic efficacy and clinical feasibility of PHES subtests and their combinations, the combination of NCT-B and LTT is recommended for the diagnosis of MHE.
ABSTRACT
Objective:To prospectively guide the change of chemotherapy regimen in mouse 5-fluorouracil (5-FU) resistance subcutaneous xenograft tumor model derived from gastric cancer patients by the early changes of MRI apparent diffusion coefficient (ADC), and to compare the difference of tumor load between ADC guided dressing change group and volume guided dressing change group.Methods:From January to June 2020, thirty patient-derived xenografts mouse models were established using 5-FU resistant gastric cancer cells coming from patients, and were randomly divided into experimental group and control group by AdaBoost algorithm, with 15 mice in each group. On the 26th day after transplantation, all mice began chemotherapy with 5-FU as the first-line chemotherapy drug, and underwent MR examination once every two days, including T 2WI and diffusion weighted imaging (DWI). Volumes of tumors were measured using an open-source software ITK-SNAP and values of ADC were measured on ADC maps. According to the change rate of tumor ADC value in the experimental group and the tumor volume growth rate in the control group, the replacement time of chemotherapy drugs was determined, and 5-FU was replaced by paclitaxel. The end point of the experiment was the day that the mice entered the cachexia state. Independent-sample t test was used to compare the difference of tumor load between the two groups. Results:After 5-FU treatment, the ADC value of the two groups both increased. The ADC value began to decline on the 4th day after chemotherapy, and the experimental group continued chemotherapy with paclitaxel instead of 5-FU at this time point. The tumor volume growth rate of the control group increased significantly on the 6th day after chemotherapy (from 8.6% to 16.1%), and the control group used paclitaxel instead of 5-FU chemotherapy at this time point. The observed end point was on the 18th day after chemotherapy. The tumor load of the experimental group [(1.82±0.09) cm 3] was lower than that of the control group [(2.01±0.09) cm 3], and the difference was statistically significant ( t=2.25, P=0.033). On the 16th day after chemotherapy in the experimental group and the 18th day after chemotherapy in the control group, the time of paclitaxel administration in both groups was 12 days. The tumor load in the experimental group [(1.61±0.12) cm 3] was also lower than that in the control group [(2.01±0.09) cm 3], and the difference was statistically significant ( t=2.03, P=0.040). Conclusions:For the subcutaneous transplantation model of 5-FU resistant gastric cancer mice, according to the early changes of tumor ADC value after chemotherapy, the replacement of chemotherapy drugs can obtain a lower tumor load, suggesting that it is a feasible method to optimize the chemotherapy regimen.
ABSTRACT
Objective: To investigate the efficacy and safety of enhanced recovery after surgery (ERAS) in perioperative management of patients with gallbladder carcinoma. Methods: The data of the patients with gallbladder carcinoma admitted at Peking Union Medical College Hospital between January 2017 and December 2021 were analyzed retrospectively. There were 69 males(42.1%) and 95 females(57.9%),with age of (64.0±10.3) years(range:37 to 89 years). Patients were divided into ERAS group(n=53) and normal group(n=111) according to whether they were treated with ERAS measures during the perioperative period.The basic characteristics of the two groups were matched by propensity score matching,and then the perioperative information was compared between the two groups. Categorical variables were presented as absolute numbers or frequencies. Differences between study groups were analyzed using χ2 test, Fisher's exact test, t-test, or Mann-Whitney U test, as appropriate. Results: Each group had 45 patients after propensity score matching with well-balanced basic characteristics. There was no difference in basic characteristics, operation time,bleeding,complication,and hospitalization expenses between two groups(all P>0.05). Compared with the normal group,time of ambulation (M(IQR)) (1(1) day vs. 2(2) days;Z=-3.839,P<0.01),postoperative anal exhaust time (2(1) days vs. 3(1) days;Z=-3.013,P=0.003),feeding time(2(1) days vs. 2(1) days;Z=-3.647,P<0.01),postoperative (5(2) days vs. 7(4) days;Z=-3.984,P<0.01) and total(8(4) days vs. 13(6) days;Z=-3.605,P<0.01) hospitalization time were shorter in ERAS group. Postoperative complications occurred in 12 patients. According to the Clavien-Dindo classification,6,4,and 2 patients were classified as grade Ⅰ,Ⅱ,and Ⅲa,respectively. Conclusion: The ERAS measures is safe and effective for perioperative management of patients with gallbladder carcinoma, enhancing patient recovery and shortening hospitalization time without increasing complication or hospitalization cost.

The metabolites of four diterpenoids are phase Ⅰ metabolites.
ABSTRACT
OBJECTIVE To compare the phar macokinetics o f ligustrazine hydrochlori de,salvianic acid and rosemarinic acid from Shenxiong glucose injection (SGI)in normal and acute myocardial ischemia (AMI)rats. METHODS Male SD rats were randomly divided into normal group and model group ,with 9 rats in each group. AMI model was established by isoproterenol hydrochloride modeling method. Three rats in each group were selected for model verification. The remaining 6 rats in each group were given SGI (1.2 mL/kg)or equal volum of normal saline via tail vein ;0.3 mL blood was collected through orbital venous bush 0.083,0.167,0.333,0.5,0.75,1,1.5,2,3,5 h after administration. Using luteoloside as internal standard ,the plasma concentrations of ligustrazine hydrochloride ,salvianic acid and rosemarinic acid were determined by ultra performance liquid chromatography-tandem mass spectrometry. Pharmacokinetic parameters were fitted by WinNonlin 8.1 software,and statistical analysis was performed by SPSS 18.0 software. RESULTS The linear ranges of ligustrazine hydrochloride ,salvianic acid and rosmarinic acid were 0.06-29.96,0.01-5.15 and 0.006-3.09 μ g/mL(all r>0.99),respectively. The results of methodological investigation were all in line with the requirements of Chinese Pharmacopoeia (2020 edition). Compared with normal rats ,CLz of ligustrazine hydrochloride in AMI model rats was significantly increased (P<0.05);t1/2 and Vz of salvianic acid were significantly prolonged or increased (P<0.05);but the cmax and AUC 0-5 h were significantly decreased (P<0.05);AUC0-5 h of rosmarinic acid was significantly decreased (P<0.05). CONCLUSIONS The exposure levels of salvianic acid and rosmarinic acid in SGI are lower in AMI model rats than in normal rats ,and the elimination of ligustrazine hydrochloride in AMI model rats is stronger than that in normal rats.
ABSTRACT
ObjectiveTo analyze the effective components of Periploca forrestii against rheumatoid arthritis(RA)by targeting tumor necrosis factor (TNF)-α based on network pharmacology and experimental verification. MethodThe preliminary research of the research group found that the alcohol extracts of P. forrestii (CDLF and CQAF) had significant anti-RA activities,and 10 monomers with such activities were identified. The anti-RA activities of active monomers,CDLF, and CQAF were compared by the enzyme-linked immunosorbent assay (ELISA)with interleukin(IL)-6,nitric oxide (NO),IL-1β, and prostaglandin E2(PGE2)as indicators. Network pharmacology was employed to analyze the possible molecular mechanism of P. forrestii against RA. The targeting ability of P. forrestii chemical monomers to TNF-α was verified by TNF-α molecular docking,surface plasmon resonance (SPR), and TNF-α-induced L929 injury model. ResultELISA showed that the anti-RA activities of CDLF and CQAF were significantly stronger than those of identified 10 active monomers. Network pharmacology analysis showed that the core targets of P. forrestii against RA were signal transducer and activator of transcription protein 3 (STAT3),TNF, and IL-6. Gene Ontology(GO) analysis revealed collagen catabolism,inflammatory response,positive regulation of nuclear factor kappa-B(NF-κB) transcription factor activity,and positive regulation of B cell proliferation. Kyoto Encyclopedia of Genes and Genomes (EKGG) pathway enrichment analysis demonstrated TNF signaling pathway,phosphoinositide 3-kinase(PI3K)/protein kinase B(Akt) signaling pathway,NF-κB signaling pathway,Toll-like receptor signaling pathway,mitogen-activated protein kinase(MAPK) signaling pathway, etc. Verification experiments by TNF-α molecular docking,SPR, and TNF-α-induced L929 injury model found that CDLF and CQAF had good binding activities and could manifestly antagonize TNF-α. However, the active components separated and identified from CDLF and CQAF did not show the same anti-TNF-α activity. ConclusionThe CDLF and CQAF of P. forrestii may treat RA by targeting TNF-α. The experiments found that the isolated chemical components had weaker binding activity to TNF-α than CDLF and CQAF. Meanwhile,the research group isolated chemical components with a minimum mass fraction of 0.25 ng·g-1 from P. forrestii, which suggested that the active components generated by binding to TNF-α with anti-RA activities were presumedly trace components .
ABSTRACT
ObjectiveTo explore the mechanism of Shenxiong glucose injection (SGI) in inhibiting hydrogen peroxide (H2O2)-induced oxidative damage in H9c2 cells by tandem mass tags (TMT)-labeled quantitative proteomics. MethodH9c2 cells cultured in vitro were exposed to H2O2 for inducing oxidative damage. The cell viability was measured by cell proliferation and cytotoxicity assay (MTS), followed by peptide fractionation by high performance liquid chromatography (HPLC) and protein expression detection in H9c2 cells by ultrahigh performance liquid chromatography-mass spectrometry. MaxQuant (v1.5.2.8) was utilized for data retrieval, and the high-resolution mass spectrometry was conducted to screen out differentially expressed proteins, which were then subjected to gene ontology (GO) and Kyoto encyclopedia of genes and genomes (KEGG) enrichment analysis. The protein expression levels of perilipin 2 (Plin2) and tropomyosin 1 (Tpm1) in cells were measured by Western blot. ResultThe spectral analysis yielded 48 608 specific peptide fragments and 5 903 quantifiable proteins. Compared with the model group,the SGI group exhibited 82 differentially expressed proteins,of which 22 were up-regulated and 60 were down-regulated. GO analysis results showed that the differentially expressed proteins were mainly involved in biological processes such as programmed cell death regulation,regulation of cell proliferation,cardiovascular system development, and cell migration. As revealed by KEGG analysis, these proteins were mainly related to peroxisome proliferator-activated receptor (PPAR),focal adhesion,phosphatidylinositol 3-kinase/protein kinase B(PI3K/Akt),and Ras-related protein 1 (Rap1) pathways. Western blot results demonstrated that compared with the model group,SGI significantly increased the Plin2 protein expression and decreased the Tpm1 protein expression (P<0.01),consistent with the proteomics results. ConclusionSGI may inhibit cell apoptosis and antagonize H2O2-induced cell oxidative damage by regulating PPAR,focal adhesion,PI3K/Akt and Rap1 pathways,which should be further verified by subsequent experiments.
ABSTRACT
A detection method of ultra-performance liquid chromatography-tandem mass spectrometry(UPLC-MS/MS) was established to detect concentrations of isoorientin, orientin, quercetin, vitexin and kaempferol-3-O-β-D-glucoside in H9 c2 cells and applied to the pharmacokinetic study of Polygonum orientale extract in the cells. H9 c2 cells were treated with 100 μg·mL~(-1) P. orientale extract and then they and the corresponding nuclei, mitochondria and Golgi bodies were collected at the set time. After protein precipitation, UPLC-MS/MS was used to determine concentrations of isoorientin, orientin, quercetin, vitexin and kaempferol-3-O-β-D-glucoside in the whole cells and subcellular structures. Also, related pharmacokinetic parameters were calculated. The results showed that the peak time was 8 h for all these components. Orientin, vitexin, quercetin and isoorientin have high affinities to nuclei and mitochondria, while the affinity of kaempferol-3-O-β-D-glucoside is higher with mitochondria compared to nuclei. It is suggested that these chemical components of P. orientale may mainly act on nuclei or mitochondria to exert pharmacological effects of protecting cardiomyocytes.

To study the active chemical components and mechanism of Liangfu Dropping Pills in treatment of gastrointestinal diseases. The UHPLC-Q-TOF-MS method was employed to analyze the components of Liangfu Dropping Pills in plasma. The protein targets of the absorbed compounds were predicted in the TCMSP database and the SwissTargetPrediction database. The targets associated with gastrointestinal diseases were collected from OMIM, CTD, GeneCards, and DrugBank. The common target genes between components and diseases were screened out for the building of protein-protein interaction(PPI) network in the STRING database. Metascape was used to carry out gene ontology(GO) and Kyoto encyclopedia of genes and genomes(KEGG) pathway enrichment analysis. Cytoscape was employed to construct the PPI network diagram and absorbed component-target network diagram. The molecular docking between the components absorbed in blood and potential key targets was performed by AutoDock vina 4.2.6 to screen and verify the main active components and targets. Twelve chemcial components were identified in Liangfu Dropping Pills, in which four components were absorbed in blood, including galangin, rhamnocitrin, galangin 3-methyl ether, and α-cyperone. These components acted on 189 common targets which were mainly involved in the cell responses to nitrogen compounds, organic cyclic compounds, and hormones, and enriched in the PI3 K-Akt signaling pathway, Foxo signaling pathway, and IL-17 signaling pathway. Molecular docking results showed that the four components had strong affinity with core targets. The material basis of Liangfu Dropping Pills treating gastrointestinal diseases may be galangin, rhamnocitrin, galangin 3-methyl ether, and α-cyperone. This study provides a theoretical basis for further development and application of Liangfu Dripping Pills.

The present study is to investigate the absorption characteristics of the main components in Polygonum orientale extract in normal and isoproterenol-induced myocardial ischemia model rats with everted intestinal sac models. Intestinal sac fluid samples were collected in different part of intestine(duodenum, jejunum, ileum, colon) at different time after administration of different concentration of P. orientale extract(5.0,10.0, 20.0 mg·mL~(-1)). An UPLC-TQD method was employed for the determination of six components including orientin, isoorientin, vitexin, protocatechuic acid, kaempferol-3-O-β-D-glucoside and quercitrin in the intestinal sac samples. The absorption rate and cumulative absorption were calculated to analyze the intestinal absorption characteristics of six components in normal and myocardial ischemia model rats. The P-glycoprotein(P-gp) inhibitor was applied to investigate influence of intestinal absorption of six components in P. orientale extract. The results showed that the main absorption sites were concentrated on the duodenum at low concentration, while they were the colon at the medium concentration and the ileum at high concentration in control groups. In the condition of myocardial ischemia model, the main absorption sites focus on the ileum and jejunum at low concentration; the main absorption sites were in the ileum at the medium concentration and main absorption sites were the duodenum and ileum at high concentration. Compared with the normal group, the absorption rate and cumulative absorption of the six components significantly decreased in the model group. P-gp inhibitor markedly increased the absorption rate and cumulative absorption of six components in the model group, inferring that the 6 components may be the substrates of P-gp, and the mechanism needs further study. In this study, it is revealed that the six components of P. orientale extract can be absorbed into the intestinal sac, and it is an effective method to assess the intestinal absorption characteristics of P. orientale extract through everted intestinal sac model, providing data support for the clinical application and further development of P. orientale.

OBJECTIVE@#To compare the therapeutic effect on type 2 diabetes mellitus (T2DM) complicated with angina pectoris of coronary heart disease between the combined therapy of acupuncture and western medication and the simple administration of western medication.@*METHODS@#A total of 134 patients with T2DM and angina pectoris of coronary heart disease were randomly divided into two groups, i.e. an acupuncture plus medication group (67 cases, 3 cases dropped off) and a medication group (67 cases, 4 cases dropped off). The routine western medication was used according to symptoms in the patients of both groups. In the acupuncture plus medication group, on the base of medication, acupuncture was applied to Jianshi (PC 5), Quchi (LI 11), Neiguan (PC 6), etc. The needles were retained for 20 min in each treatment and 3 treatments of acupuncture were required weekly. The treatment was given consecutively for 8 weeks in the two groups. Separately, before and after treatment, the symptom scores of TCM were observed and the indexes were detected, including glycolipid metabolism [fasting plasma glucose (FPG), 2-h plasma glucose (2hPG), glucosylated hemoglobin (HbA1c), triacylglycerol (TG) and total cholesterol (TC)], islet β cell function [homeostasis model assessment-β (HOMA-β), homeostasis model assessment-IR (HOMA-IR), fasting insulin (FINS) and insulin sensitivity index (ISI)], cardiac function indexes [cardiac output (CO), early diastolic peak velocity/late diastolic peak velocity (E/A), left ventricular end diastolic diameter (LVEDD) and left ventricular ejection fraction (LVEF)], as well as electrocardiogram QT dispersion (QTd). Besides, the clinical therapeutic effects were compared between the two groups.@*RESULTS@#After treatment, the TCM symptom scores and the values of FPG, 2hPG, HbA1c, TG, TC, HOMA-IR, FINS, E/A and LVEDD as well as QTd were all lower than those before treatment in the two groups (@*CONCLUSION@#The combined therapy of acupuncture and medication is effective in treatment of T2DM complicated with angina pectoris of coronary heart disease. Such therapy effectively improves glucolipid metabolism, islet β cell function, cardiac function and myocardial blood supply. Its curative effect is better than the simple administration of western medicine.

OBJECTIVE@#To evaluate the protective effects of salvianolate on percutaneous coronary intervention (PCI) related myocardial injury or myocardial infarction after elective PCI in non-ST-segment elevation acute coronary syndrome (NSTE-ACS) patients.@*METHODS@#A total of 149 patients with NSTE-ACS who underwent elective PCI were enrolled. The patients were randomly allocated in a 1:1 ratio to the salvianolate group (74 cases) or the control group (75 cases). After exclusion criteria of coronary angiography, 60 patients with PCI therapy remained in the salvianolate group and 68 in the control group. The incidence and the severity of PCI related myocardial injury or myocardial infarction, in addition to major adverse cardiac events (MACEs) during 1 year follow-up after PCI were studied between the two groups. Multivariate logistic regression analysis was used to determine the independent factors for PCI related myocardial injury or myocardial infarction after elective PCI.@*RESULTS@#Compared with the control group, salvianolate treatment reduced the incidence of PCI related severe myocardial injury or myocardial infarction (11.7% vs. 26.5%, P=0.035). The rate of MACEs or all-cause death within 1 month or 1 year after the procedure was not significantly different between the two groups.@*CONCLUSIONS@#Periprocedural treatment with salvianolate reduces the incidence of PCI related severe myocardial injury or myocardial infarction, although it does not influence clinical prognosis.

ABSTRACT
Objective:To evaluate the efficacy of Jianpi-Yishen Decoction in treating sarcopenia aged patients with syndrome of spleen-kidney deficiency and cold-dampness. Methods:Eighty-two sarcopenia aged patients admitted to Beijing Longfu hospital from January of 2018 to May of 2019 were selected and divided into the control group and the observation group with 41 patients in each group according to the random number table. Patients in the control group were given routine western treatment such as nutritional support. In the observation group, the patients were given Jianpi-Yishen Decoction based on the control group. Both groups were treated for 12 weeks. Before and after the treatment, the upper limb muscle strength, scores of symptoms of syndrome of spleen-kidney deficiency and cold-dampness, the efficacy of traditional Chinese medicine syndrome, and serum level of 1,25-dihydroxyvitamin D3 were compared between the two groups. Results:During the treatment, one patient in the control group was dropped out. The total effective rate was 95.1% (39/41) in the observation group and 72.5% (29/40) in the control group, and the difference between the two groups was statistically significant ( χ2=6.103, P=0.013). After the treatment, the scores of languid limbs, cold limbs, weak waist and knee, clear urine and loose stool in the observation group were obviously lower than those of the control group ( t values were 9.964, 12.510, 14.103, 13.415, 14.599, respectively, all Ps<0.01). The left hand grip strength (52.75±7.91 kg vs. 46.10 ± 7.22 kg, t=3.954) and the right hand grip strength (53.93 ± 8.09 kg vs. 48.55 ± 7.17 kg, t=3.169) were both higher than those of the control group ( P<0.01). Serum level of 1,25-dihydroxyvitamin D3 (23.90 ± 3.34 ng/L vs. 19.44 ± 3.15 ng/L, t=6.184) were higher than those of the control group ( P<0.01). Conclusions:Jianpi-Yishen Decoction in treating sarcopenia aged patients with syndrome of spleen-kidney deficiency and cold-dampness can effectively relieve the symptoms, up-regulate serum level of 1,25-dihydroxyvitamin D3 with clinical efficacy.
ABSTRACT
Objective::To screen out active fraction from Euphorbia fischeriana, separate active components from E. fischeriana and explore structure-activity relationships, in order to analyze and identify chemical compositions of petroleum ether fraction from E. fischerian ethanol extract by ultra-performance liquid chromatography with quadrupole-time-of flight mass spectrometry (UPLC-Q-TOF-MS). Method::The anti-tumor activities of petroleum ether, ethyl acetate, n-butanol and water extracts from E. fischeriana were tested by methyl thiazolyl tetrazolium(MTT)method. A variety of modern chromatographic separation methods were used to separate active compounds from petroleum ether layer. Compounds were isolated. Their structures were identified by NMR technique. The structure-activity relationships between anti-tumor activities and structures of compounds were investigated. UPLC-Q-TOF-MS technique was used to identify the structures of petroleum ether extract from E. fischeriana. Mass spectrometry was performed in the positive ion mode using ESI ion sources. Result::Six compounds were isolated from petroleum ether fraction. They were jolkinolide A, jolkinolide B, 17-hydroxyjolkinolide A, 17-hydroxyjolkinolide B, euphopilolide and atis-16-en-13(s)-hydroxy-3, 14-dione. A total of 23 peaks were identified based on the comparison of retention times, accurate masses and fragmentation patterns with available standard compounds and literatures. Among them, there were 19 diterpenoids, 2 polyphenols, 1 fatty acid and 1 triterpenoid. Peaks No.18 and No.21 were tentatively identified as new compounds. Conclusion::The petroleum ether fraction showed a potential anti-tumor activity. The structure-activity relationships were discussed. UPLC-Q-TOF-MS technology can be used to quickly and accurately identify the structures, so as to provide a reference for its quality evaluation and active ingredient research.

ABSTRACT
Cerebellar malfunction can lead to sleep disturbance such as excessive daytime sleepiness, suggesting that the cerebellum may be involved in regulating sleep and/or wakefulness. However, understanding the features of cerebellar regulation in sleep and wakefulness states requires a detailed characterization of neuronal activity within this area. By performing multiple-unit recordings in mice, we showed that Purkinje cells (PCs) in the cerebellar cortex exhibited increased firing activity prior to the transition from sleep to wakefulness. Notably, the increased PC activity resulted from the inputs of low-frequency non-PC units in the cerebellar cortex. Moreover, the increased PC activity was accompanied by decreased activity in neurons of the deep cerebellar nuclei at the non-rapid eye-movement sleep-wakefulness transition. Our results provide in vivo electrophysiological evidence that the cerebellum has the potential to actively regulate the sleep-wakefulness transition.
ABSTRACT
OBJECTIVE:To s tudy the intestinal absorption differences of 6 kinds of active constituents of Polygonum orientale (kaempferol,isokaempferol,vitexin,protocatechuic acid ,kaempferol-3-O-β-D-glucoside and quercetin )in normal and myocardial ischemia(MI)model rats. METHODS :UPLC-MS/MS method was adopted to determine the contents of 6 active components in the intestinal circulatory perfusion fluid. Totally male SD 80 rats were divided into normal group and model group ,with 40 rats in each group. Model group was given isoproterenol hydrochloride (50 mg/kg) subcutaneously to induce MI model;normal group was given constant volume of normalsaline, once a day , for consecutive 2 days. 24 h after successful molding ,normal group and model group received in-situ intestinal circulatory perfusion experiment. The effects of different concentration s of P. orientale extract(5.0,10.0, 20.0 mg/mL),different intestinal segments (duodenum,jejunum,ileum,colon),P-glycoprotein(P-gp)inhibitors(verapamil) and bile on the intestinal absorption of each constituent were explored. RESULTS :The linear ranges of concentrations of kaempferol, isokaempferol, vitexin, protocatechuic acid , kaempferol-3-O-β-D-glucoside and quercetin were 3.15-50.40, 3.21-51.31,1.63-52.43,1.60-50.94,1.31-20.97,8.07-129.25 µg/mL(r>0.999). The lower limits of quantification were 7.86, 8.45,6.52,4.00,3.28,16.14 ng/mL,respectively. RSDs of precision ,matrix effect and stability tests were all lower than 11%; the accuracy were 85.64%-107.65%,which were in line with the requirements of biological sample quantification analysis. Except for there was no statistical significance in the absorption of kaempferol absorption in duodenum of model group at different concentrations,absorption of other five constituents in duodenum of normal and model rats increased with the increase of the concentration of active constituents ,and absorption of medium- and/or high- concentration active constituents (except quercetin )in model group was significantly lower than normal group (P<0.05). In normal group ,the absorption of kaempferol was more in jejunum,ileum and colon ,isokaempferol was more in ileum ,vitexin and protocatechuic acid were more in jejunum and ileum , kaempferin-3-O- β-D-glucoside was more in duodenum ,jejunum and colon ,quercetin was more in colon ;in the model group ,the absorption of Polygonum orientale in jejunum and colon was more ,the absorption of isokaempferol in 4 intestinal segments was little different ,vitexin was mainly absorbed in ileum ,protocatechuic acid and kaempferol- 3-O-β-D-glucoside was mainly absorbed in jejunum ,quercetin was mainly absorbed in duodenum and ileum ;in the same intestine ,the absorption of constituents in the model group was less than normal group. After adding verapamil ,absorption of all constituents in the normal group increased ,but the difference was not statistically significant (P>0.05);absorption of kaempferol ,isokaempferol,vitexin,protocatechuic acid and kaempferol- 3-O-β-D-glucoside were all increased significantly in model group (P<0.05),while there was no statistical significance in the increase of quercetin (P>0.05). After the bile flowed into the duodenum ,absorption of protocatechuic acid was increased significantly in normal group (P<0.05);absorption of other active constituents were increased significantly in model group,except for isokaempferol and quercetin (P<0.05). CONCLUSIONS :Six active constituents of P. orientale were absorbed in the whole intestine of normal and MI model rats ,and the absorption of above constituents may be enhanced more significantly by P-gp inhibitor and bile under pathological condition.
