Chinese herbal medicines for treating ulcerative colitis via regulating gut microbiota-intestinal immunity axis / 中草药·英文版

Ulcerative colitis (UC) is one of types of inflammatory bowel disease with high recurrence. Recent studies have highlighted that microbial dysbiosis as well as abnormal gut immunity are crucial factors that initiate a series of inflammatory responses in the UC. Modulating the gut microbiota-intestinal immunity loop has been suggested as one of key strategies for relieving UC. Many Chinese herbal medicines including some of single herb, herbal formulas and the derived constituents have been reported with protective effect against UC through modulating gut microbiome and intestinal immunity. Some clinical trials have shown promising results. This review thus focused on the current knowledge on using Chinese herbal medicines for treating UC from the mechanism aspects of regulating intestinal homeostasis involving microbiota and gut immunity. The existing clinical trials are also summarized.

Effects and evaluation of different processing and drying methods on components in Paeoniae Radix Alba / 中国中药杂志

The present study evaluates different processing and drying methods and investigates their effects on the chemical components in Paeoniae Radix Alba via content determination. The fresh medicinal materials of Paeoniae Radix Alba collected from Bozhou of Anhui province were processed(boiled and peeled) and dried(hot air-dried, infrared-dried, and microwave-dried) at different temperatures(40, 50, 60 and 70 ℃), and the 11 components(monoterpene glycosides, polyphenols, tannin, and benzoic acid) in Paeoniae Radix Alba were determined by ultra-performance liquid chromatography coupled to triple quadrupole with electrospray tandem mass spectrometry(UPLC-TQ-MS). Then the compounds in processed and dried samples were analyzed by partial least squares discriminant analysis(PLS-DA) and orthogonal partial least squares discriminant analysis(OPLS-DA), and the contribution rates of differential components were evaluated by variable important in projection(VIP). The results indicated that the samples obtained by different processing and drying methods could be distinguished. Albiflorin, gallic acid, 1,2,3,4,6-pentakis-O-galloyl-β-D-glucose, and benzoic acid were the common differential components in boiled Paeoniae Radix Alba. Benzoic acid was the common differential component in peeled Paeoniae Radix Alba. Gallic acid was the common differential component in Paeoniae Radix Alba dried by different methods. The samples could not be distinguished after drying at different temperatures due to the lack of common differential components. This study is expected to provide a reference for the selection of processing and drying methods and the optimization of processing parameters.

Research progress on mechanism of active components of Chinese materia medica in treatment of osteoporosis based on signaling pathway / 中草药

Osteoporosis is a systemic skeletal disease that causes a huge medical burden on patients and society. Drug treatment is the main intervention for anti-osteoporosis, but objectively existing adverse reactions reduce the patient's compliance and affect the effect of medication. Traditional Chinese medicine has good curative effect and safety in the prevention and treatment of osteoporosis, but its mechanism of action needs to be further studied. The pathway regulates the progress of osteoporosis and is one of the main targets for osteoporosis pathological mechanism and pharmacological research. In recent years, an increasing number of studies have been made on the regulatory mechanism of osteoporosis signaling pathways by active ingredients of Chinese materia medica. Recent research results on the active components of Chinese materia medica interfering with biological signaling pathways was reviewed in this article, in order to provide ideas for new drug development, basic research, and clinical applications for osteoporosis.

Comparative study on differences of Paeonia lactiflora from different habitats based on fingerprint and chemometrics / 中国中药杂志

This study aims to compare the differences of Paeonia lactiflora from different habitats by establishing fingerprint. The fingerprint of P. lactiflora was established by UPLC. The samples collected from Sichuan,Hebei,Henan,Shanxi and Anhui were analyzed. The common peaks were identified by UPLC-Q-TOF/MS. The relative peak area of the common peaks was analyzed through similarity evaluation system( 2012 edition) for chromatographic fingerprint of traditional Chinese medicine developed by the National Pharmacopoeia Commission. Twelve common peaks were obtained and ten components were identified by reference substance and literature comparison. The similarity of each sample to the reference fingerprint is greater than 0. 900. However,all samples were clearly divided into 5 groups according to habitats after PLS-DA analysis. The peaks 2,6( ethyl gallate),10( galloypaeoniflorin) and 12( benzoyl paeoniflorin) were found to be the main difference components between the samples from five different habitats through the VIP value map. The study found that the variety of ingredients in the different areas are basically similar. But there are some differences in the content of the four components. The results of this study can provide reference at choosing and utilizing P. lactiflora from different places comprehensively.

Physicochemical properties of peanut oil-based diacylglycerol and their derived oil-in-water emulsions stabilized by sodium caseinate.

High purity peanut oil-based diacylglycerol (PO-DAG) (94.95 wt%) was prepared via enzymatic glycerolysis from peanut oil (PO). The resulting dominance of DAGs was proven to greatly influence the properties of corresponding fresh or frozen-thawed emulsions. Stable fresh oil-in-water emulsions were produced using either PO-DAG or PO, with stability enhanced by increased concentrations of Na-CN. The lower equilibrium interfacial tension along with greater negative ζ-potential of PO revealed that Na-CN was preferentially adsorbed to the PO interface. Adding 0.05 mol/L NaCl to the PO emulsions minimized depletion flocculation caused by the unadsorbed Na-CN, but further NaCl addition increased oil droplet size and concomitant coalescence. For the PO-DAG emulsions, adding 0.2 mol/L NaCl did not significantly (p>0.05) affect their ζ-potential but adding 0.05 or 0.1 mol/L NaCl lowered ζ-potential, although NaCl at these concentrations increased oil droplet size and coalescence. Freezing-thawing process considerably weakened the stability of PO-DAG emulsions.

Influence of hyperbaric oxygen treatment on blood pressure and the rebleeding in patients with hypertensive intracranial hemorrhage / 中国综合临床

Objective To investigate the influence of hyperbaric oxygen treatment (HBOT) on blood pressure (BP) and the incidence of rebleeding in patients with hypertensive intracranial hemorrhage (HICH)Methods One hundred and twenty patients with HICH were treated for 60 min with 100% oxygen at 2.0 absolute atmospheres (ATA) daily when the condition was stable and BP was controlled ideally. Blood pressure was measured before the patients were sent into the HBO chamber and remeasured following completion of each HBOT session and 1 hour later. Rebleeding was monitored during and after each HBO session . Results HBOT caused a significant elevation of systolic BP in 25.83% (31/120) patients and a significant decrease in 16.67% (20/120) patients (P ＜0. 05 ),whereas the rest 57.5% (69/120) patients had no significant changes,when the BP was measured right after the HBOT session. The mean diastolic BP increased in 69 (57. 50% ) patients and decreased in 4. 17%(5/120) patients (P ＜ 0. 05 ), whereas we found no significant changes in the rest 46 (38. 33% ) patients. No differences were found in the comparison of BP before and 1 hour after the HBOT session and no one suffered from rebleeding during and after HBOT session. Conclusions HBOT may cause temporal blood pressure changes in most patients with HICH, however, it will not cause an increasing incidence of rebleeding if the patient's condition is stable and the blood pressure has been well controlled.

Hydroxysafflor yellow A up-regulates HIF-1alpha via inhibition of VHL and p53 in Eahy 926 cell line exposed to hypoxia / 药学学报

In present study, we investigated the mechanism of regulating HIF-1alpha expression by hydroxysafflor yellow A (HSYA) in Eahy 926 cell line under 1% O2 hypoxia. Eahy 926 cells were incubated with HSYA (100, 10 and 1 micromol x L(-1)) under hypoxia for the indicated time after treatment. Cell proliferation rate was detected using MTT assays. VHL and p53 location and protein expression were analyzed by immunocytochemical stain. HIF-1alpha, VHL and p53 mRNA expression were detected by RT-PCR. Protein expression of HIF-1alpha, VHL and p53 were assayed by Western blotting method. HSYA at 100 micromol x L(-1) increased Eahy 926 cells proliferation rate under hypoxia. HIF-1alpha mRNA and protein expression were up-regulated in the presence of HSYA. VHL, p53 mRNA and protein expression decreased significantly after 8 hours of treatment under hypoxia. HSYA protected Eahy 926 cells from hypoxia, and up-regulated HIF-1alpha expression partially via its inhibition of VHL and p53 expression.
