This study aims to explore the molecular mechanism of Ganoderma against gastric cancer based on network pharmacology, molecular docking, and cell experiment. The active components and targets of Ganoderma were retrieved from Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform(TCMSP), and gastric cancer-related targets from GeneCards and Online Mendelian Inheritance in Man(OMIM). The protein-protein interaction(PPI) network of the common targets was constructed with STRING, followed by Gene Ontology(GO) term enrichment and Kyoto Encyclopedia of Genes and Genomes(KEGG) pathway enrichment analysis of the common genes based on Bioconductor and R language. The medicinal-disease-component-target network and medicinal-disease-component-target-pathway network were established by Cytoscape. Molecular docking was performed between β-sitosterol(the key component in Ganoderma) and the top 15 targets in the PPI network. Cell experiment was performed to verify the findings. A total of 14 active components and 28 targets of Ganoderma were retrieved, and the medicinal and the disease shared 25 targets, including caspase-3(CASP3), caspase-8(CASP8), caspase-9(CASP9), and B-cell lymphoma-2(BCL2). The common targets involved 72 signaling pathways and apoptosis and p53 signaling pathway may play a crucial role in the effect of Ganoderma against gastric cancer. β-sitosterol had strong binding activity to the top 15 targets in the PPI network. The in vitro cell experiment demonstrated that β-sitosterol inhibited gastric cancer AGS cell proliferation by inducing cell apoptosis and cell cycle arrest in the S phase, which might be related to the regulation of the p53 pathway. This study shows the multi-component, multi-target, and multi-pathway characteristics of Ganoderma against gastric cancer, which lays a scientific basis for further research on the molecular mechanism.

OBJECTIVES:
To analyze the characteristics of sudden death associated with sexual activity to provide recommendations for forensic identification.
METHODS:
A retrospective analysis was conducted on autopsy cases accepted by Forensic Identification Center of Huazhong University of Science and Technology from 1998 to 2018, and a total of 15 cases of sudden death associated with sexual activity were screened out. The general information, case data and pathological changes of 15 cases were collected to find the relationship between sexual activity and sudden death.
RESULTS:
The ratio of male to female was 1.5∶1. The average age of males was 50.1 years and that of females was 35.0 years. Coronary artery diseases and brain diseases accounted for most of the cases (12/15). Sexual partners were associated with locations of deaths and body dumping behaviors.
CONCLUSIONS
Sudden death associated with sexual activity, although rare, may occur in people over 30 years old with pre-existing heart or brain diseases, which should be paid attention to in forensic practice.

OBJECTIVETo study the effect of BAM bone grafting combined with inactivated autologous porous bone flap in repairing skull defect in rats.
METHODSSeventy-two Wistar rats with skull defect were randomly divided into control group, inactivated autologous bone flap group (AB group), BAM bone-induced artificial bone material group (BAM group), and inactivated autologous bone flap with BAM bone-induced artificial bone group (BAM+AB group). The bone healing was evaluated with micro-CT and the new bone formation was assessed with histological staining at 1, 2, and 3 months after modeling.
RESULTSInactivated porous bone flap combined with BAM bone-induced artificial bone effectively induced vascular and fibrous tissue regeneration and osteogenesis in the cranial defects. With the inactivated porous bone flap as the scaffold, BAM bone-induced artificial bone obviously promoted the restoration of the skull appearance in the rats with cranial defects.
CONCLUSIONInactivated autologous bone flap group and BAM bone-induced artificial bone material can promote skull healing and restoration of the original skull appearance, and can be used for reconstruction of the local anatomy of the skull surface.

Chinese materia medica resource (CMM resource) is the foundation of the development of traditional Chinese medicine. In the study of sustainable utilization of CMM resource, adopting innovative theory and method to find new CMM resource is one of hotspots and always highlighted. Pharmacophylogeny interrogates the phylogenetic relationship of medicinal organisms (especially medicinal plants), as well as the intrinsic correlation of morphological taxonomy, molecular phylogeny, chemical constituents, and therapeutic efficacy (ethnopharmacology and pharmacological activity). This new discipline may have the power to change the way we utilize medicinal plant resources and develop plant-based drugs. Phylogenomics is the crossing of evolutionary biology and genomics, in which genome data are utilized for evolutionary reconstructions. Phylogenomics can be integrated into the flow chart of drug discovery and development, and extends the field of pharmacophylogeny at the omic level, thus the concept of pharmacophylogenomics could be redefined in the context of plant pharmaceutical resources. This contribution gives a brief discourse of knowledge pedigree of pharmacophylogeny, epistemology and paradigm shift, highlighting the theoretical and practical values of pharmacophylogenomics. Many medicinally important tribes and genera, such as Clematis, Pulsatilla, Anemone, Cimicifugeae, Nigella, Delphinieae, Adonideae, Aquilegia, Thalictrum, and Coptis, belong to Ranunculaceae family. Compared to other plant families, Ranunculaceae has the most species that are recorded in China Pharmacopoeia (CP) 2010. However, many Ranunculaceae species, e. g., those that are closely related to CP species, as well as those endemic to China, have not been investigated in depth, and their phylogenetic relationship and potential in medicinal use remain elusive. As such, it is proposed to select Ranunculaceae to exemplify the utility of pharmacophylogenomics and to elaborate the new concept empirically. It is argued that phylogenetic and evolutionary relationship of medicinally important tribes and genera within Ranunculaceae could be elucidated at the genomic, transcriptomic, and metabolomic levels, from which the intrinsic correlation between medicinal plant genotype and metabolic phenotype, and between genetic diversity and chemodivesity of closely related taxa, could be revealed. This proof-of-concept study regards pharmacophylogenomics as the updated version of pharmacophylogeny and would enrich the intension and spread the extension of pharmacophylogeny. The interdisciplinary knowledge and techniques will be integrated in the proposed study to promote development of CMM resource discipline and to boost sustainable development of Chinese medicinal plant resources.

OBJECTIVEImprovement in lung function was reported after acupuncture treatment of chronic obstructive pulmonary disease (COPD), but little is known about the underlying mechanisms. Because an immune response imbalance could be seen in COPD, we hypothesize that electroacupuncture (EA) may play a role in regulating inflammatory cytokines and contribute to lung protection in a rat model of smoke-induced COPD.
METHODSA COPD model using male Sprague-Dawley rats exposed to cigarette smoke was established. The rats were randomly divided into four groups (control, sham, COPD, and COPD plus EA), and COPD model was evaluated by measuring pulmonary pathological changes and lung function. EA was applied to the acupuncture point Zusanli (ST36) for 30 min/d for 14 d in sham and COPD rats. Bronchoalveolar lavage fluid (BALF) was used to measure levels of tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β), and malonaldehyde (MDA).
RESULTSCompared with the control rats, COPD rats had significant changes in lung resistance (RL) and lung compliance (CL) (both P<0.01), bronchi and bronchiole airway obstruction (P<0.01), and levels of MDA, TNF-α, and IL-1β (P<0.01). There were no significant differences between the control and the sham groups. Compared with the COPD rats, the COPD plus EA rats had decreased RL and increased CL (both P<0.05), and reduced bronchi and bronchiole airway obstruction (P<0.05, P<0.01, respectively), while levels of TNF-α, IL-1β, and MDA in BALF were lowered (P<0.05 and P<0.01, respectively). However, TNF-α and IL-1β levels of the EA group rats remained higher than those of the control group (P<0.05).
CONCLUSIONEA at ST36 can reduce lung injury in a COPD rat model, and beneficial effects may be related to down-regulation of inflammatory cytokines. The anti-inflammatory and antioxidant effects may prolong the clinical benefit of EA.

OBJECTIVETo research the bacteriostatic effects of Qingkailing Injection Extract (QKLIE) and combination therapy of Qingkailing Injection (QKLI) and antibiotics on bacteria carrying New Delhi metallo-3-lactamase 1 (NDM-1) blaNDM-1 resistance gene, and to determine their minimal inhibitory concentrations (MIC).
METHODSThe antimicrobial experiments of QKLIE (Radix Isatidis, baicalin, gardenia, honeysuckle) and combination therapy of QKLI and antibiotics were performed by using the agar dilution method and K-B method. The MIC was determined from each extract.
RESULTSThere were different degrees of inhibitory effects on resistant bacteria carrying blaNDM-1 by extracts from main components of QKLI. Of them, the inhibitory effect of baicalin was the best and the MIC of the resistant bacteria was 0.015 g/mL to WD, 0.020 g/mL to WX, 0. 005 g/mL to WJ, and more than 0.020 g/mL to pGEX-4T-NDM-1/DH5alpha (GST-NDM-1), respectively. The MIC value of each extract was sequenced from high to low as baicalin, honeysuckle, gardenia, and Radix Isatidis. Furthermore, combination therapy of QKLI and antibiotics greatly enhanced the antimicrobial activity of each antibiotics when used alone, showing very obvious antibacterial effects on multidrug resistant bacteria carrying blaNDM-1 gene. Of them, the optimal effects were obtained when combined with penicillins (penicillin G, mezlocillin, piperacillin/ tazobactam, ampicillin/sulbactam), with the antibacterial effects improved by 10 folds. The antibacterial effects of other kinds of antibiotics were improved to some extent. Conclusions QKLIE and combination therapy of QKLI and antibiotics showed better bacteriostatic effects on resistant bacteria carrying blaNDM-1 gene. This study provided theoretical bases for drug development, medication and treatment for super-resistant bacteria carrying blaNDM-1.

BACKGROUNDPolyunsaturated omega-3 fatty acids may beneficially influence healing processes and patient outcomes. The aim of this research was to study the clinical efficacy of fish oil enriched total parenteral nutrition in elderly patients after colorectal cancer surgery.
METHODSFifty-seven elderly patients with colorectal cancer were enrolled in this prospective, randomized, double-blind, controlled clinical trial. All patients received isocaloric and isonitrogenous total parenteral nutrition by continuous infusion (20 - 24 hours per day) for seven days after surgery. The control group (n = 28) received 1.2 g/kg soybean oil per day, whereas the treatment group (n = 29) received 0.2 g/kg fish oil and 1.0 g/kg soybean oil per day. Blood samples were taken pre-operatively, and at days one and eight after the operation. The plasma levels of CD4, CD8, CD4/CD8, interleukin 6 (IL-6) and tumor necrosis factor α (TNF-α) were measured. Clinical outcomes were then analysed.
RESULTSPatient characteristics were comparable between the two groups. At day eight post-surgery, IL-6, TNF-α and CD8 titres were lower in the treatment group when compared to the control group; these results reached statistical significance. In the treatment group, there were fewer infectious complications and incidences of systemic inflammatory response syndrome (SIRS), and shorter lengths of hospital stay were observed. The total cost of medical care was comparable for the two groups. No serious adverse events occurred in either group.
CONCLUSIONSFish oil 0.2 g/kg per day administrated to elderly patients after colorectal surgery was safe and may shorten the length of hospital stay and improve clinical outcomes.

OBJECTIVETo investigate whether Candida albicans-native phospholipomannan (PLM) induce an inflammation response through Toll-like receptor(TLRé2 in human acute monocytic leukemia cell line (THP-1) cells.
METHODSHuman THP-1 monocytes were challenged with PLM in vitro. The mRNA expressions of TLR2, TLR4, proinflammatory cytokine [interleukin(IL)-6], and chemokine (IL-8) were assayed by real time reverse transcription polymerase chain reaction. The secretions of IL-6 and IL-8 were measured by enzyme-linked immunosorbent assay. The expression of TLR2 was analyzed with Western blot.
RESULTSPLM increased the mRNA expressions and secretions of proinflammatory cytokines (IL-6) and chemokines (IL-8) in THP-1 cells (all P=0.0000). PLM up-regulated the mRNA and protein levels of TLR2 (P=0.0000), whereas the mRNA level of TLR4 was not altered. PLM hydrolyzed with β-D-mannoside manno hydrolase failed to induce gene and protein expressions of TLR2, IL-6, and IL-8. Anti-TLRS-neutralizing antibody blocked the PLM-induced secretions of IL-6 and IL-8 in THP-1 cells (P = 0.0003, P = 0.0010).
CONCLUSIONCanidada albicans-native PLM may contribute to the inflammatory responses during Candida infection in a TLR2-dependent manner.
