ObjectiveTo obtain high-quality chloroplast genome information on Stemona tuberosa and clarify its structure， sequence features， and phylogenetic status. MethodThe Illumina NovaSeq 6000 and PacBio RS Ⅱ platforms were used for library construction and sequencing of S. tuberosa， respectively. The data from both sequencing platforms were combined and subjected to bioinformatics analysis for genome assembly and base correction， resulting in a high-quality chloroplast genome. Subsequently， sequence features， repetitive sequences， gene diversity， and phylogeny were analyzed. ResultThe chloroplast genome size of S. tuberosa was determined to be 154 379 bp. The structure of the chloroplast genome followed the typical quadripartite circular form， consisting of a pair of inverted repeat regions （IRs） with a length of 27 074 bp， a small single-copy region （SSC） of 17 924 bp， and a large single-copy region （LSC） of 82 307 bp. The average GC content was 37.86%. A total of 121 genes were annotated， including 30 tRNA genes， four rRNA genes， and 87 protein-coding genes. Among them， six tRNA genes and 12 protein-coding genes contained introns. In the chloroplast genome of S. tuberosa， 49 long repetitive sequences and 59 single-nucleotide simple sequence repeats （SSRs） were identified. Comparative analysis of chloroplast genomes among four Stemona species revealed high diversity in the ycf1 and ndhF genes. The phylogenetic tree constructed based on the chloroplast genome showed consistent classification with the current taxonomic status of S. tuberosa. ConclusionThe high-quality chloroplast genome of S. tuberosa was successfully assembled， providing valuable information on the structure and sequence features of chloroplast genomes in four Stemona species， including S. tuberosa. These findings lay a foundation for the identification， evolution， and phylogenetic studies of medicinal plants in the genus Stemona.

Discussion on the mechanism of Yanghe Decoction in treating chronic osteomyelitis based on network pharmacology and molecular docking / 国际中医中药杂志

Objective:To study the active components and their potential mechanism of Yanghe Decoction for the treatment of chronic osteomyelitis (CO) via the methods of network pharmacology and molecular docking.Methods:Active components and action targets of Yanghe Decoction were screened from TCMSP, BATMAN-TCM and relevant literature. GeneCards, OMIM, DisGeNET, and PharmGKB databases were used to predict the targets for the CO. Cytoscape 3.8.0 software and STRING database were used to build the networks of "Chinese materia medica-active components-potential targets" and "protein-protein interaction", and according to topological parameters in the network, the core active components as well as Hub genes were screened. MCODE plug was used to accomplish clustering analysis of protein modules in PPI network. Then, intersection targets were enriched and analyzed by GO and KEGG in KOBAS database. Finally, molecular docking was carried out with the help of Autodock tool platform to predict the binding ability between the main active components and key targets.Results:A total of 120 active components of Yanghe Decoction and 402 targets were obtained; 1 464 CO-related targets were screened, and there were 103 intersection target genes of Yanghe Decoction-CO, 110 active components related to intersection targets, which mainly contained some flavonoids and Phytosterols, such as quercetin, Kaempferol, and Beta-Sitosterol. There were 9 Hub genes, including TNF, IL6, AKT1, etc., and 4 protein modules which involved the regulation of immune inflammatory response, vascular microcirculation, bone development, and formation, material synthesis and metabolism and other physiological processes. 193 signaling pathways and 1 552 GO results were acquired in KOBAS database. Molecular docking results showed that the active compounds had good binding activity with key targets based on the minimum binding energy of less than - 5 kcal/mol.Conclusion:The mechanism in the treatment of CO with Yanghe Decoction is a complex process of multiple components, multiple targets, and multiple pathways. It mainly regulates targets such as TNF, IL-6, CXCL8, VEGFA, and AKT1 through pathways such as TNF signaling pathway, IL-17 signaling pathway, and Toll-like receptors, participating in local inflammatory reactions, microcirculation, and bone cell metabolism in chronic osteomyelitis, and interfering with the immune escape mechanism of pathogenic bacteria.

Anthraquinones,dianthrones and tannins are the main active ingredients of Rheum tanguticum. In this study the three components were determined by HPLC,and the results were analyzed by multiple comparisons,principal components analysis(PCA)and correspondence analysis(CA). The results showed that the contents of components in different growing areas and types(wild and cultivated) reached a significant level(P<0. 05). Baiyu county,Xiaojin county and Ruoergai county had obvious advantages in the accumulation of catechin hydrate,rhien and sensenoside A respectively. The principal component was different in two growing type and the wild environment was conducive to combined anthraquinones accumulation. For active components,normalized planting was better than retail cultivating. Therefore,the effect on the accumulation of chemical components in Rh. tangusticum,should be taken into full account in the selection of the cultural base of Rh. tanguticum. The standardized cultivating is superior to retail cultivating in terms of the accumulation of active ingredients,and standardized planting is inferior to the wild.

Heart Rate Variability Biofeedback Increased Autonomic Activation and Improved Symptoms of Depression and Insomnia among Patients with Major Depression Disorder

OBJECTIVE: Autonomic imbalance is considered a psychopathological mechanism underlying major depressive disorder (MDD). Heart rate variability (HRV) is an index for autonomic activation. Poor sleep quality is common among patients with MDD. HRV biofeedback (BF) has been used for regulating autonomic balance among patients with physical illness and mental disorders. The purpose of present study was to examine the effects of HRV-BF on depressive symptoms, sleep quality, pre-sleep arousal, and HRV indices, in patients with MDD and insomnia. METHODS: In this case-controlled study, patients with MDD and Pittsburgh Sleep Quality Index (PSQI) score higher than 6 were recruited. The HRV-BF group received weekly 60-minute protocol for 6 weeks, and the control group who have matched the age and sex received medical care only. All participants were assessed on Beck Depression Inventory-II, Back Anxiety Inventory, PSQI, and Pre-Sleep Arousal Scale. Breathing rates and electrocardiography were also performed under resting state at pre-testing, and post-testing conditions and for the HRV-BF group, also at 1-month follow-up. RESULTS: In the HRV-BF group, symptoms of depression and anxiety, sleep quality, and pre-sleep arousal were significantly improved, and increased HRV indices, compared with the control group. Moreover, in the HRV-BF group, significantly improved symptoms of depression and anxiety, decreased breathing rates, and increased HRV indices were detected at post-testing and at 1-month follow-up, compared with pre-testing values. CONCLUSION: This study confirmed that HRV-BF is a useful psychosocial intervention for improving autonomic balance, baroreflex, and symptoms of depression and insomnia in MDD patients.

Objective@#To explore the effects of Xialiqi Capsules(XLQ) on the expressions of the proliferating cell nuclear antigen (PCNA) and caspase-3 in the prostate tissue of the BPH rat model.@*METHODS@#Fifty male SD ratswereequally randomized into groups A (sham operation control), B (BPH model control), C (high-dose XLQ), D (low-dose XLQ), and E (finasteridecontrol) andthe BPH modelswere established by subcutaneous injection of testosterone propionate at 0.5 mg per kilogram of the body weight per day for 30 days after castration. After modeling, the animals in groups A and B were treated intragastricallywith normal saline, while those in C, D, and E with XLQ at 1.20 and 0.61 g per kilogram of the body weight per day or finasterideat 0.8 mg per kilogram of the body weight per day, respectively, all for 30 days. Then,the bilateral prostates were harvestedfrom the rats for calculation of the prostatic index (prostate wet weight/ body weight) and determination of the expressions of PCNA and caspase-3 in the prostate tissue by immunohistochemistry and immunofluorescence staining, respectively.@*RESULTS@#The prostate wet weight and prostate index were significantly increased in group B as compared with group A, (［1326±60］ vs［471±17］ g, P<0.01; ［2.89±0.18］ vs ［1.06±0.06］ mg/g, P<0.01), but decreased in groups C (［914±36］ g;［2.02±0.08］ mg/g), D (［1 099±46］g;［2.39±0.11］ mg/g), and E (［817±53］ g;［1.83±0.10］ mg/g)in comparison with B (P<0.01), with statistically significant differences among groups C, D, and E(P<0.01) and most significantly in E.The PCNA level in the prostate tissue wasremarkably higher in group B than in A, but lower in groups C, D and E than in B. The expression of caspase-3 was down-regulatedin group B as compared with A, but up-regulated in groups C, D and E in comparison with B, most significantly in E.@*CONCLUSIONS@#Xialiqi Capsules can effectively reduce the prostate wet weight and prostatic index of in rats with BPH by inhibiting the level of PCNA and promoting the expression of caspase-3.

Two new steroidal saponins isolated from Anemarrhena asphodeloides / 中国天然药物

Two new steroidal saponins, named timosaponin P (1) and timosaponin Q (2), were isolated from the rhizome parts of Anemarrhena asphodeloides Bunge using various chromatographic methods. Their structures and absolute configurations were elucidated by a combination of spectroscopic and spectrometric data, including 1D, 2D NMR, HR-ESI-MS and ECD calculations, and this is the first time the absolute configuration of C-23 of steroidal saponin was confirmed by ECD calculations.
