With the completion of the "Human Genome Project" and the smooth progress of the "Herbal Genome Project", the research wave of RNAomics is gradually advancing, opening the research gateway for the modernization of traditional Chinese medicine (TCM) and initiating the post-genome era of medicinal plant RNA research. Therefore, this article proposes for the first time the concept of HerbRNomes, which involves constructing databases of medicinal plant, medicinal fungus, and medicinal animal RNA at different stages, from different origins, and in different organs. This research aims to explore the role of HerbRNA in self-genetic information transmission, functional regulation, as well as cross-species regulation functional mechanisms and key technologies. It also investigates application scenarios, providing a theoretical basis and research ideas for the resistance of TCM or medicinal plants to adversity and stress, molecular assistant breeding, and the development of small nucleic acid drugs. This article reviews recent research progress in elucidating the molecular mechanisms of the transmission and expression of genetic information, self-regulation and cross-species regulation of herbs at the RNA level, along with key technologies. It proposes a development strategy for small nucleic acid drugs based on HerbRNomes, providing theoretical support and guidance for the modernization of TCM based on HerbRNomes research.

ObjectiveSpatial working memory (SWM) is an important function in cognitive behavior, and working memory impairment can seriously affect the patient’s life and cause great stress to the patient. Intermittent theta burst stimulation (iTBS) has been shown to regulate working memory function by entrainment of neural oscillations in different frequencies of the brain, but its regulation of working memory-related neural oscillations and their synchronization is not clear. The purpose of this study was to study the effect of iTBS on neural oscillation and synchronization in local and transbrain regions of rats, and to explore the mechanism of iTBS in regulating working memory. MethodsTwenty-four rats were randomly divided into four groups according to their age and whether they received iTBS stimulation (AS: adult stimulation group, AC: adult control group, ES: elderly stimulation group, EC: elderly control group). Using the methods of time-frequency distribution, phase synchronization and phase-amplitude coupling analysis, the changes of local field potential signal neural oscillations in the prefrontal and hippocampal brain regions of theta and gamma bands in the process of spatial working memory behavioral tasks in each group of rats were compared and analyzed, and the relationship between the changes of neural oscillations in the two brain regions and the changes in spatial working memory ability of rats was judged based on the Pearson correlation coefficient. ResultsWith the increase of age, the time taken by the elderly rats to learn the spatial working memory task rules increased significantly (P=0.005 6), and the time taken by iTBS stimulation to learn the SWM task rules in adult rats (P=0.001 1) and elderly rats(P=0.009 0) was shortened. At the same time, compared with adult rats, the time-frequency energy of theta and gamma band neural oscillations in the prefrontal and hippocampal brain regions of elderly rats (theta: P<0.000 1; gamma: P<0.000 1) and phase-amplitude coupling across brain regions (PFC-HPC: P=0.000 2; HPC-PFC:P=0.027 7) decreased to a certain extent, and iTBS stimulation could increase the time-frequency energy of neural oscillations of adult rats (theta: P<0.000 1; gamma: P<0.000 1) and elderly rats (theta: P=0.014 4; gamma:P=0.000 6) and the phase-amplitude coupling effect across brain regions in elderly rats (PFC-HPC: P=0.018 0; HPC-PFC: P=0.022 1). In addition, the time-frequency energy and phase-amplitude coupling of signals in each frequency band of the two brain regions were positively correlated with the behavioral accuracy of rats, while the phase synchronization of theta band and gamma band neural oscillations in the two brain regions during working memory was not correlated with the behavioral accuracy. ConclusioniTBS can enhance SWM ability and cognitive function in elderly rats, and this improvement is associated with increased coupling of time-frequency energy and cross-brain phase amplitude of neural oscillations across theta and gamma bands during SWM tasks. Similarly, in adult rats, iTBS enhances SWM ability and cognitive function by increasing the time-frequency energy of theta and gamma band neural oscillations in both brain regions during SWM tasks. Furthermore, in addition to the main findings, this study provides evidence supporting the state-dependent effects of iTBS stimulation to some extent.

In order to standardize the quality control of traditional Chinese medicine(TCM) dispensing granules, the Chinese Pharmacopoeia Commission has promulgated and implemented 200 national drug standards for TCM dispensing granules, but there are still varieties of TCM dispensing granules without unified standards. Many provinces have actively invested in the formulation of provincial standards for TCM dispensing granules to make up for the gaps in standards for varieties of traditional Chinese medicine dispensing granules other than the national standards. By the end of July 2022, 29 provincial-level administrative regions have successively promulgated and implemented a total of 5 602 provincial standards for TCM dispensing granules, involving more than 400 varieties. In order to better understand the formulation and characteristics of provincial standards, this study took 105 provincial standards that have been promulgated and implemented in Henan province as an example, and comprehensively analyzed the formulation and characteristics through quality control indicators such as dry extract rate of raw materials, contents of index components and their transfer rates, specifications and so on. The formulation and characteristics of the same TCM dispensing granules in the provincial standards of different provinces were further analyzed, in order to provide reference for the formulation of provincial standards of TCM dispensing granules and the implementation of national standards.

Starting with the relationship between mulberry leaves and silkworm droppings as food and metabolites, this study systematically compared the chemical components, screened out differential components, and quantitatively analyzed the main differential components based on ultra-high performance liquid chromatography with quadrupole time-of-flight mass spectrometry(UPLC-Q-TOF-MS) and UPLC-Q-TRAP-MS combined with principal component analysis(PCA) and orthogonal partial least squares-discriminant analysis(OPLS-DA). Moreover, the in vitro enzymatic transformation of the representative differential components was studied. The results showed that(1) 95 components were identified from mulberry leaves and silkworm droppings, among which 27 components only exist in mulberry leaves and 8 components in silkworm droppings. The main differential components were flavonoid glycosides and chlorogenic acids.(2) Nineteen components with significant difference were quantitatively analyzed, and the components with significant differences and high content were neochlorogenic acid, chlorogenic acid, and rutin.(3) The crude protease in the mid-gut of silkworm significantly metabolized neochlorogenic acid and chlorogenic acid, which may be an important reason for the efficacy change in mulberry leaves and silkworm droppings. This study lays a scientific foundation for the development, utilization, and quality control of mulberry leaves and silkworm droppings. It provides references for clarifying the possible material basis and mechanism of the pungent-cool and dispersing nature of mulberry leaves transforming into the pungent-warm and dampness-resolving nature of silkworm droppings, and offers a new idea for the study of nature-effect transformation mechanism of traditional Chinese medicine.

OBJECTIVE:
To evaluate the protective effect of excretory-secretory proteins from Trichinella spiralis muscle larvae (Ts-MES) on sepsis-induced myocardial injury in mice.
METHODS:
Eighty male BALB/C mice were randomized equally into sham-operated group, myocardial injury group, Ts-MES treatment group and dexamethasone treatment group. In the latter 3 groups, sepsis-induced myocardial injury models were established by cecal ligation and perforation; the sham operation was performed by exposure of the cecum without ligation or perforation. Forty minutes after the operation, the mice were given intraperitoneal injections 150 μL PBS, 20 μg TS-MES or 0.3 mg/kg dexamethasone as indicated. At 12 h after the operation, 6 mice were randomly selected from each group for echocardiography, and 8 mice were used for observing the survival rate within 72 h. The remaining 6 mice were examined for myocardial pathologies with HE staining and serum levels of NTPro-BNP and cTnI with ELISA; the expressions of TNF-α, IL-6, IL-10 and TGF-β in the serum and myocardial tissue were detected using ELISA and qRT-PCR.
RESULTS:
Compared with the sham-operated mice, the septic mice showed significantly decreased cardiac function indexes (LVEF, LVFS, and E/A) with lowered survival rate within 72 h (P < 0.001) and significantly higher myocardial injury scores and serum levels of NTPro-BNP and cTnI (P < 0.01). Treatment with TS-MES significantly improved the cardiac function and 72-h survival rate (P < 0.05) and lowered the myocardial injury scores and serum levels of NTPro-BNP and cTnI (P < 0.05) in the septic mice. Compared with the sham-operated mice, the septic mice had obviously increased TNF-α and IL-6 levels in the serum and myocardial tissue (P < 0.001), which were significantly lowered by treatment with TS-MES (P < 0.05). TS-MES and dexamethasone both increased the levels of IL-10 and TGF-β in the septic mice, but the changes were significant only in TS-MES-treated mice (P < 0.05).
CONCLUSION
Ts-MES are capable of protecting against myocardial injury in septic mice by reducing the production of pro-inflammatory cytokines and enhancing the levels of regulatory cytokines.

As China is implementing the policy of "Announcement on Ending the Pilot Work of Chinese medicine formula gra-nules", the standard of Chinese medicine formula granules has gradually become the focus of industry development. Up to now, 196 national drug standards for Chinese medicine formula granules have been published by China, which guaranteed the production quality of Chinese medicine formula granules. However, there are still several challenges such as the rational application of national drug standards and the enrichment and improvement of varieties. The basic content of the issued national drug standards for Chinese medicine formula granules was analyzed and compared with the quality standard provisions of the corresponding decoction pieces in the Chinese Pharmacopoeia(2020 edition) in this paper. This paper discussed the main characteristics of paste-forming rate of each medicinal raw materials, "quantity-quality" transformation, equivalent ratio, and so on, and clarified the characteristics of the national standard for Chinese medicine formula granules. This paper provided references for achieving the unified quality control and meeting the overall quality requirements of Chinese medicine formula granules.

OBJECTIVE:
Through showing the full picture of double-arm controlled clinical research and systematic review evidence in the field of orally administrated Chinese herbal medicine (CHM) for treatment of lung cancer, to provide a reference for future clinical research and to indicate a direction for future systematic reviews.
METHODS:
A comprehensive search of clinical controlled studies was performed regarding orally administered CHM treatment for lung cancer published from January 1970 to September 2020. The language was restricted to Chinese and English. Relevant data were extracted, the quality of systematic reviews was evaluated, and the research evidence was visually displayed.
RESULTS:
Randomized controlled trials were the most common type of research design. The research sample sizes were typically small. Oral CHM showed certain curative advantages in treating lung cancer. The key stages in oral CHM intervention for lung cancer are chemotherapy, radiotherapy, and late palliative treatment. The advantageous outcomes of oral CHM treatment of lung cancer are the short-term efficacy, quality of life, and adverse reactions. The perioperative stage, overall survival, pharmacoeconomic evaluation, and Chinese medicine decoctions are weak research areas.
CONCLUSIONS
CHM has staged and therapeutic advantages in treating lung cancer. The overall methodological quality is poor, and the level of evidence requires improvement. It is necessary to carry out large-scale, standardized, and higher-quality research in the superior and weak areas of CHM treatment of lung cancer.

Objective:To investigate the epidemic trend and risk change of acquired immunodeficiency syndrome (AIDS) complicated with malignant tumors after combination antiretroviral therapy (cART).Methods:The types of malignant tumors in patients with AIDS at different stages of cART were analyzed among anti-human immunodeficiency virus (HIV)-positive population in Hubei Province screened in National AIDS/HIV prevention and control information system from 1st January, 2004 to 31st December, 2018. The standardized incidence ratios(SIR) of malignant tumors in AIDS patients was analyzed based on the incidence of malignant tumors in the general population in Hubei Province or China in 2013. The changes in risks for development of malignant tumors in AIDS patients at different cART stages from 2004 to 2013 and 2014 to 2018 were compared.Chi-square test was used for statistical analysis.Results:Three hundred and twenty-three out of 22 994 AIDS patients were diagnosed with malignant tumors. Non-Hodgkin lymphoma(NHL) and cervical cancer were most common types in acquired immunodeficiency syndrome-defining cancers (ADC), while liver cancers and lung cancers were the most common types in non-acquired immunodeficiency syndrome-defining cancers (NADC). The overall risk of malignancy in AIDS patients was similar to that in the general population (SIR=1.06, χ2=0.62, P=0.426). However, the risks of Kaposi sarcoma, NHL, Hodgkin lymphoma, cervical cancer, and head and face cancers (excepting nasopharyngeal cancer) in AIDS patients were significantly higher than those in the general population (SIR=834.09, 9.65, 13.33, 5.22 and 2.94, respectively, χ2=11 747.27, 625.54, 56.65, 184.21 and 13.66, respectively, all P<0.01). The risks of lung cancer, colorectal anal cancer, stomach cancer and breast cancer in AIDS patients were significantly lower than those in the general population (SIR=0.33, 0.36, 0.43 and 0.45, respectively, χ2=33.43, 12.84, 9.01 and 7.21, respectively, all P<0.05). The SIR of cervical cancer, liver cancer and colorectal anal cancer from 2014 to 2018 were 4.06, 0.43 and 0.10, respectively, which were significantly lower than those from 2004 to 2013 (7.42, 1.96 and 0.84, respectively). The differences were all statistically significant ( χ2=5.39, 19.52 and 10.86, respectively, all P<0.05). Conclusions:At present, there are no significant differences of the incidences of malignant tumors between AIDS patients and general population, but the tumor types are different. The most common malignant tumors in this region are NHL and cervical cancer, which should be noted that HIV screening among patients with such tumors is conducive to comprehensive treatment to improve the efficacy.
