Secondary metabolites of medicinal plants are extremely important to human health because of their special pharmacological activities or efficacy. They are the main source of drugs, health care products, and cosmetics. As human beings continue to pursue health and longevity, the demand in the pharmaceutical market continues to grow. It becomes especially important to improve the production and quality of secondary metabolites of medicinal plants. Plant secondary metabolites are a kind of adaptation of plants to their environment and are the result of the interaction between plants and biotic and abiotic factors during the long-term evolution process. The production and accumulation of secondary metabolites in medicinal plants are mainly affected by plant genetic factors and environmental factors. Among them, light environment is extremely important for their synthesis. Therefore, light regulation has long been a research focus for many scholars in China and abroad. In this article, we the recent research progress on the effects of light regulation on the secondary metabolites of medicinal plants were reviewed, mainly focusing on the effects of light quality, light intensity and photoperiod, in order to provide theoretical basis and practical guidance for the efficient production of secondary metabolites with important pharmacological activities.

Objective To explore the anti-tumor mechanism of saffron (Crocus sativus L.) by network pharmacology and reverse molecular docking techniques. Methods The main chemical components of saffron were obtained by searching published literature and TCMSP database. The potential targets of these components were predicted using PharmMapper server. The corresponding target genes were identified from UniProt database. The underlying anti-tumor targets of saffron were obtained by mapping the disease genes of cancer or tumor with GeneCards, OMIM and TTD databases. Cytoscape software was used to construct the action target network of saffron active components. The protein-protein interaction analysis was performed by String database, and the GO function and KEGG pathway enrichment analysis were performed by Metascape platform. Finally, molecular docking was performed to evaluate the binding of main components with their potential targets. Results A total of 9 active ingredients in saffron including quercetin, kaempferol, isorhamnetin, picrocrocin and crocin I, were identified, which might act on 37 key targets including AKT1, CCND1, MMP9, EGFR, TP53, involved in P53, TNF and other signaling pathways. Molecular docking indicated modest binding potency through hydrogen bonding, and hydrophobic interactions. Conclusion The anti-tumor effect of saffron was evaluated via the network of components-targets-pathways, which might provide a foundation for further research.

Objective To explore the efficacy of the resolving depression and tranquilizing herbal sachets in alleviating sleep disorders of soldiers in naval vessels. Methods Fifty-nine soldiers with sleep disorders (PSQI scale score ≥8 and SAS scale score ≥50) were selected before training at sea, and were randomly divided into sachet treatment group, mindfulness meditation group and control group. During the training period, the sachet treatment group was given traditional Chinese medicine sachet treatment, the mindfulness meditation group was trained in mindfulness meditation, and the control group was not given any intervention. Results Compared with the control group, the PSQI and SAS scores of soldiers in both the experimental sachet treatment group and the positive meditation group were significantly improved; compared with the pre-intervention data, the PSQI and SAS scores of both the positive meditation group and the sachet treatment group were significantly decreased, and the degree of decrease was comparable. Conclusion The homemade improving depression and tranquilizing TCM sachets have the effect of alleviating the sleep disorders of naval troops served on vessels, which is equivalent to mindfulness meditation. It is easy to use and operate, which is suitable for promotion in the military.

Acute hematogenous osteomyelitis (AHO) is the type of its kind diagnosed most frequently in pediatric patients. In the past decade, the incidence of methicillin-resistant Staphylococcus aureus infections has increased in children. The more complex situation of infections may lead additionally to deep vein thrombosis (DVT), septic pulmonary embolism, pneumonia, empyema, endocarditis, bacteremia and septic shock. Hence, hospital stays are often lengthy and patients often critically ill. Since delayed appropriate therapy can lead to chronic osteomyelitis, as well as impairments in bone growth and development, early accurate diagnosis and prompt initiation of appropriate treatment remain central principles in the evaluation and treatment of AHO. Therefore, care of children with AHO inevitably requires an organized and interdisciplinary approach to reach timely, comprehensive and accurate diagnoses so that effective treatment may be carefully planned and enacted with subsequent monitoring of the child until clinical resolution is achieved. This review is devoted exclusively to the management of AHO in children, providing an update on the current understanding of existing evidence and future directions to improve care for pediatric AHO.

Objective:To compare the clinical effects on new bone formation and foot-ankle function between proximal tibial bone transport and distal tibial bone transport in the treatment of massive bone defects after tibial osteomyelitis debridement.Methods:From July 2012 to July 2017, 42 patients with chronic tibial osteomyelitis received bone transport surgery at Department of Orthopaedics, Nanfang Hospital.According to the Cierny-Mader classification for chronic osteomyelitis, all of them belonged to diffusive tibial osteomyelitis (type IV).Of them, 32 were treated by proximal tibial bone transport after tibial osteomyelitis debridement.In the proximal group, there were 27 males and 5 females, aged from 17 to 65 years and involving 20 left and 12 right sides. The other 10 cases received distal tibial bone transport. In the distal group, all of them were male, aged from 25 to 63 years and involving 6 left and 4 right sides. The 2 groups were compared in terms of external fixation index (EFI) and American Orthopaedic Foot & Ankle Society(AOFAS) Ankle and Hindfoot Scale.Results:There were no significant differences between the 2 groups in the preoperative general data such as gender, age or osteomyelitis site, indicating the 2 groups were comparable ( P>0.05). Both groups obtained complete follow-up. The proximal group was followed up for 590.1 d ± 287.3 d and the distal group for 615.6 d ± 130.6 d, showing no significant difference between groups ( P>0.05). In the proximal group 2 cases developed talipes equinovalgus after bone transport while in the distal group 3 cases did, and surgical intervention was needed for them. Surgical intervention was also carried out for16 cases of non-union at the docking site in the proximal group and for 2 ones in the distal group. The EFI was 76.2 d/cm±50.0 d/cm for the proximal group and 84.3 d/cm ± 59.9 d/cm for the distal group, showing no significant difference between groups ( P>0.05). The AOFAS scores were 81.4±10.1 for the proximal group and 60.0±5.9 for the distal group, showing a significant difference ( P<0.05). Conclusion:In the treatment of massive bone defects after tibial osteomyelitis debridement, no significant difference has been observed in the effect on bone formation between proximal tibial bone transport and distal tibial bone transport, but the former transport may have a less adverse effect on foot-ankle function.
