ABSTRACT
Depression is a severe mental disorder among public health issues. Researchers in the field of mental health and clinical psychiatrists have long been faced with difficulties in slow treatment cycles, high recurrence rates, and lagging efficacy. These obstacles have forced us to seek more advanced and effective treatments. Research has shown that novel drug delivery strategies for natural medicinal plants can effectively improve the utilization efficiency of the active molecules in these plants and therefore improve their efficacy. Currently, with the development of treatment technologies and the constant updating of novel drug delivery strategies, the addition of natural medicinal antidepressant therapy has given new significance to the study of depression treatment against the background of novel drug delivery systems. Based on this, this review comprehensively evaluates and analyses the research progress in novel drug delivery systems, including nanodrug delivery technology, in intervention research strategies for neurological diseases from the perspective of natural medicines for depression treatment. This provided a new theoretical foundation for the development and application of novel drug delivery strategies and drug delivery technologies in basic and clinical drug research fields.

Traditional Chinese medicines (TCMs) have been regularly prescribed to treat and prevent diseases for thousands of years in the eastern part of the Asian continent. Thus, when the coronavirus disease 2019 (COVID-19) epidemic started, TCM was officially incorporated as a strategy by the National Health Commission (NHC) for the treatment of COVID-19 infection. TCMs were used to treat COVID-19 and had a significant effect on alleviating symptoms, delaying disease progression, improving the cure rate, and reducing the mortality rate in China. Therefore, China's National Health Commission officially approved Qingfei Paidu decoction, Xuanfei Baidu decoction, Huashi Baidu decoction, Lianhua Qingwen capsules, Jinhua Qinggan granules, and Xuebijing for COVID-19 treatment. This review evaluates and summarizes the use of TCMs against infectious diseases and the composition, clinical efficacy, and mechanisms of the NHC-approved "three Chinese medicines and three Chinese recipes" for COVID-19 treatment. The three Chinese medicines and three Chinese recipes have been demonstrated to be highly effective against COVID-19, but there is a lack of in vivo or in vitro evidence. Most of the available data related to the potential mechanism of the three Chinese medicines and three Chinese recipes is based on virtual simulation or prediction, which is acquired via molecular docking and network pharmacology analysis. These predictions have not yet been proven. Therefore, there is a need for high-quality in vivo and in vitro and clinical studies by employing new strategies and technologies such as genomics, metabolomics, and proteomics to verify the predicted mechanisms of these drug's effects on COVID-19.
ABSTRACT
PURPOSE: The aim of this study is to explore the possible benefits of traditional Chinese medicine on the pathogenesis of psychological and mental health of COVID-19 survivors. METHODS: A literature search was conducted to confirm the effects of COVID-19 on psychological and mental health of survivors. In addition to this, on the basis of signs and symptoms, TCM were used on treat mental disorder as per suggested clinical and animal experimental data plus relevant records in classical Chinese medicine books written by Zhang Zhongiing during Han Dynasty. A series of treatment plans were prescribed for COVID-19 survivors with psychological and mental disorders. RESULTS: According to previous extensive studies focusing on effects on mental health of survivors, high incidence was observed in severe acute respiratory syndrome (SARS) and Middle East respiratory syndrome (MERS) survivors. During investigations of mental health of COVID-19 patients and survivors, it is observed that they also had symptoms of mental disorders and immune dysfunction. Furthermore, it was also proposed that depression, anxiety and post-traumatic stress disorder (PTSD) were most common mental disorders requiring special attention after the recovery from COVID-19. The symptoms of COVID-19 were analyzed, and the TCM syndrome of the depression, anxiety and PTSD after recovered from COVID19 was interpreted as internal heat and Yin deficiency. These three mental disorders pertains the category of "Lily disease", "hysteria" and "deficient dysphoria" in TCM. CONCLUSION: Lily Bulb, Rhizoma Anemarrhena Decoction and Ganmai Dazao Decoction were used to treat depression. Suanzaoren Decoction, Huanglian Ejiao Decoction and Zhizi Chi Decoction were suggested for anxiety. Moreover, Lily Bulb, Rehmannia Decoction and Guilu Erxian Decoction were the formula for PTSD.

The aim of this study was to investigate the effect of ultrasound-assisted osmotic dehydration on texture, retention of bioactive compounds, nutritional quality and metabolites of plum. The osmotic dehydration was performed using 50% glucose and sucrose in ultrasound (25â¯kHz) for 30 and 60â¯min. After osmotic treatment samples were dried at 55⯰C using hot air oven. In this study, the texture of the sample was determined by 20% compression of texture profile analysis and solute diffusion coefficient was calculated by Fick's law of diffusion. Further, the volatile compound and nutritional quality were determined. Furthermore, treatment difference of osmo-dehydrated plum on metabolites was measured by 1H NMR. The results showed that the ultrasound-assisted osmotic dehydration increased water loss and solid gain. It also increases the reduction of moisture content from the plum. Textural result of osmo-dehydrated plum in glucose increases the softness of plum and decreases hardness. Moreover, the increased antioxidant and phenolics were obtained in plum treated in 50% sucrose for 30 and 60â¯min and also at 30â¯min of glucose. Color of ultrasound-assisted osmotic dehydrated plum was also affected by treatment time and the osmotic solution used. Ultrasound-assisted osmotic dehydration reveals that water loss, solid gain, texture and bioactive compounds affected by treatment time and osmotic solution.

Depression pertains to the category of "Emotional Diseases" in traditional Chinese medicine (TCM). Its clinical symptoms are similar to the manifestations of "lily disease" from the TCM classics Synopsis of the Golden Chamber written by Zhang Zhongjing in the Han Dynasty. Also in this book, Lily Bulb and Rehmannia Decoction (LBRD) is the formula for the treatment of "lily disease". The classical herbal formula LBRD is composed of two herbs lily bulb and fresh rehmannia juice, with the function of nourishing yin and replenishing heart and lung. It has been clinically applied to treat "lily disease" for two thousand years. In this review, we focused on recent evidence linking LBRD and depression extracting data from animal and clinical studies, summarizing the primitive dosage and producing area of genuine medicinal materials of LBRD, clinical application, pharmacological mechanism and the effective substance basis for the treatment of depression. In conclusion, we discussed existing problems and future perspective. This systematic review will seek to enhance our understanding about pharmacology mechanism, herb-prescribing and recipe-constructing, and the development of novel formula for depression treatments.

BACKGROUND: Previous studies have shown beneficial effects of dietary approaches for iron deficiency anemia (IDA) control. This study was design to investigate the effect of dietary intervention treatment on children with iron deficiency anemia. METHODS: We performed a systematic review of published dietary interventions effect on IDA treatment through meta-analysis. CBM, CNKI, Wanfang database, EMBASE, VIP, PubMed and Web of science database were searched to identify studies published between January, 1980 and December, 2016. Statistical analysis was performed by Revmen5.2 software. RESULTS: Initially we retrieved for 373 studies, and then 6 studies with a total of 676 individuals were included in the analysis according to the inclusion and exclusion criteria for meta-analysis. The overall pooled estimate of odds ratio [(OR), 95% confidence intervals (95% CI)] in the dietary intervention on children with iron deficiency anemia was 6.54 (95% CI: 3.48-12.31, Z = 5.82, p<0.001) and funnel plot is symmetric. CONCLUSIONS: Our meta-analysis suggested that dietary interventions are effective in improving the iron deficiency in children with iron deficiency anemia (IDA) and should be considered in the overall strategy of IDA management.
