Enzyme-linked Immunosorbent Assay in Quality Control of Chinese Medicines： A Review / 中国实验方剂学杂志

In the quality control of Chinese medicine， the detection of active components and toxic and harmful components are two important links. Although conventional methods such as high performance liquid chromatography and liquid chromatography-mass spectrometry can accurately quantify the above substances， they have shortcomings such as complicated operation， high costs， inability of detection at any time， difficult detection of insoluble and macromolecular substances. Enzyme-linked immunosorbent assay （ELISA） can adsorb antigens or antibodies on the surface of solid carriers and realize qualitative or quantitative analysis of targets by using the specific reactions of antigens and antibodies. This method is praised for the simple operation， high sensitivity， strong specificity， simple requirements for experimental equipment， a wide application range， and low costs. In recent years， ELISA has been widely used in the quality control of Chinese medicine， especially in the content determination of mycotoxins represented by aflatoxin and the qualitative and quantitative analysis of active components. ELISA plays an increasingly important role with its unique advantages， providing new methods and ideas for the rapid quality examination of large quantities of Chinese medicines. This paper reviews the research progress in ELISA for the quality control of Chinese medicine in recent years and prospects its technical development and application prospects， aiming to provide reference and research ideas for further using this method to ensure the quality， safety， and controllability of Chinese medicine.

Progress on Prevention and Treatment of Cerebral Small Vascular Disease Using Integrative Medicine / 中国结合医学杂志

Cerebral small vessel disease (CSVD) is a senile brain lesion caused by the abnormal structure and function of arterioles, venules and capillaries in the aging brain. The etiology of CSVD is complex, and disease is often asymptomatic in its early stages. However, as CSVD develops, brain disorders may occur, such as stroke, cognitive dysfunction, dyskinesia and mood disorders, and heart, kidney, eye and systemic disorders. As the population continues to age, the burden of CSVD is increasing. Moreover, there is an urgent need for better screening methods and diagnostic markers for CSVD, in addition to preventive and asymptomatic- and mild-stage treatments. Integrative medicine (IM), which combines the holistic concepts and syndrome differentiations of Chinese medicine with modern medical perspectives, has unique advantages for the prevention and treatment of CSVD. In this review, we summarize the biological markers, ultrasound and imaging features, disease-related genes and risk factors relevant to CSVD diagnosis and screening. Furthermore, we discuss IM-based CSVD prevention and treatment strategies to stimulate further research in this field.

An N-shaped curve was found in the significant nonlinear associations between internet addiction and depression across sex, region and school stage.@*Conclusion@#Internet addiction and depression in students show significant linear and non-linear associations, which are consistent in different sexes, regions and school stages. Therefore, relevant measures should be made and implemented in each region, especially in suburb areas, so as to prevent the increasingly development of adolescents and children s Internet addiction and depression.

Research progresses on interventions of obesity in children and adolescents / 中华预防医学杂志

Childhood and adolescent obesity has become a global epidemic. The interventions mainly include lifestyle intervention, medication treatment and bariatric surgery. Among them, lifestyle intervention, especially intensive lifestyle intervention with participation of family members, is the first-line treatment for obesity in children and adolescents. Both medication and bariatric surgery are adjuvant treatments for severely obese children and adolescents. Currently, metformin is the most widely used drug for the treatment of obesity in children and adolescents in both China and other countries; orlistat and liraglutide are also the drugs that are safe and often used in other countries; other drugs are not recommended. As a tertiary prevention and treatment strategy for obesity, bariatric surgery should be carried out on the basis of good compliance from both the children and their family members, with the cooperation of multiple disciplines. Sleeve gastrectomy (SG) and Roux-en-Y gastric bypass (RYGB) are the most common types of procedure performed. Meanwhile, as a new treatment method, intra-gastric balloon procedure needs to be paid more attention to its efficacy and safety.

The collaboration of multiple departments is required to establish anenvironment to protect the spine, early detection and early intervention.

Conversion of traditional Chinese medicine (TCM) into nanomedicine:application of theory of unification of medicines and excipients / 中国中药杂志

In recent years, the use of active substances as excipients or as substitutes for other excipients in the design of modern drug delivery systems has received widespread attention, which has promoted the development of the theory of unification of medicines and excipients in the design of traditional Chinese medicine(TCM) preparations. Adopting the theory of unification of medicines and excipients to design drug delivery systems can reduce the use of excipients and thus the cost of preparations, reduce drug toxicity, increase drug solubility and biocompatibility, enhance synergistic effect, and realize targeted delivery and simultaneous delivery of multiple components. However, the research on the application of this theory in the modern drug delivery system of TCM preparations is still insufficient, with few relevant articles. In addition, the TCM active substances that can be used as the excipients remain to be catalogued. In this paper, we review the types and applications of the drug delivery systems with TCM active substances as excipients and describe their common construction methods and mechanisms, aiming to provide references for the in-depth research on the modern drug delivery systems for TCM preparations.

Application of CT pulmonary angiography in acute pulmonary embolism and right heart function / 中国康复理论与实践

ObjectiveTo explore the application value of CT pulmonary angiography (CTPA) in assessing the severity of acute pulmonary embolism (APE) and right heart function in rehabilitation patients. MethodsFrom January, 2013 to January, 2020, 133 inpatients (94 positive and 39 negative) who underwent CTPA examination in Beijing Bo'ai Hospital were involved. Positive patients were further divided into mild, moderate and severe groups based on the pulmonary artery obstruction index (PAOI). The clinical parameters and right heart function indicators were compared. Spearman correlation analysis was used to analyze the correlation between PAOI, and clinical parameters and right heart function indicators, and Logistic regression analysis was used to predict the risk factors of APE. ResultsThere was significant difference in lower extremity venous thrombosis, D-dimer, oxygen partial pressure, PAOI and left process of interventricular septum among four groups (H ≥ 12.350, P < 0.01). PAOI was moderately positively correlated with D-dimer (r = 0.443, P < 0.001) and left process of interventricular septum (r = 0.520, P < 0.001), and was weakly positively correlated with lower extremity venous thrombosis (r = 0.399, P < 0.001), left pulmonary artery diameter (r = 0.213, P = 0.014) and inferior vena cava regurgitation (r = 0.229, P = 0.008). Lower extremity venous thrombosis (OR = 7.708, P < 0.001) and left process of interventricular septum (OR = 3.641, P = 0.008) were independent risk factors for the onset of APE. The combination of the two indicators was effective for diagnosis of APE, and AUC was 0.795 (95% CI 0.715 to 0.874). ConclusionCTPA may be applied to evaluate the severity of APE and right heart function in rehabilitation patients.

The time limit was from the establishment of the database to December 1, 2020. RevMan 5.3 was used for Meta-analysis of binary variables. Random effect model was selected according to the results of heterogeneity, and odds ratio ( OR) was used as the effect index. Characteristic changes were found by subgroup analysis. Bias was published by funnel plot. Results:Nine articles were included in this Meta-analysis, with 6 articles in Chinese and 3 articles in English, respectively. The abnormal ECG changes included QTc prolongation, ST-T segment change, left axis deviation and arrhythmia. Finally, 1 975 cases were included in the exposure group, including 575 cases of abnormal ECG; 750 cases of control group, including 145 cases of abnormal ECG. Meta-analysis showed that the combined OR value [95% confidence interval ( CI)] of abnormal ECG changes was 4.41 (2.83 - 6.87), with statistical significance between the two groups ( Z = 6.56, P < 0.05); the results of subgroup analysis showed that the combined OR values (95% CI) of QTc prolongation, ST-T segment change, left axis deviation and arrhythmia were 12.30 (5.91 - 25.59), 2.74 (1.39 - 5.41), 2.93 (0.89 - 9.62) and 4.13 (2.38 - 7.17), respectively. Conclusions:Endemic arsenic poisoning may cause abnormal ECG. Prolongation of QTc caused by arsenic exposure may be the characteristic change of abnormal ECG.

Bioresponsive immune-booster-based prodrug nanogel for cancer immunotherapy

The combination of chemotherapy and immunotherapy motivates a potent immune system by triggering immunogenic cell death (ICD), showing great potential in inhibiting tumor growth and improving the immunosuppressive tumor microenvironment (ITM). However, the therapeutic effectiveness has been restricted by inferior drug bioavailability. Herein, we reported a universal bioresponsive doxorubicin (DOX)-based nanogel to achieve tumor-specific co-delivery of drugs. DOX-based mannose nanogels (DM NGs) was designed and choosed as an example to elucidate the mechanism of combined chemo-immunotherapy. As expected, the DM NGs exhibited prominent micellar stability, selective drug release and prolonged survival time, benefited from the enhanced tumor permeability and prolonged blood circulation. We discovered that the DOX delivered by DM NGs could induce powerful anti-tumor immune response facilitated by promoting ICD. Meanwhile, the released mannose from DM NGs was proved as a powerful and synergetic treatment for breast cancer in vitro and in vivo, via damaging the glucose metabolism in glycolysis and the tricarboxylic acid cycle. Overall, the regulation of tumor microenvironment with DOX-based nanogel is expected to be an effectual candidate strategy to overcome the current limitations of ICD-based immunotherapy, offering a paradigm for the exploitation of immunomodulatory nanomedicines.

Effects of NLRP3-mediated pyroptosis on olfaction dysfunction in allergic rhinitis / 中华耳鼻咽喉头颈外科杂志

Objective: To explore the relationship between NLRP3-mediated pyroptosis and olfactory dysfunction (OD) in allergic rhinitis (AR), and to evaluate the therapeutic potential of CY-09, a selective NLRP3 inhibitor for OD. Methods: An AR mouse model was established with ovalbumin, and the olfactory function of AR mice was detected by the buried food pellet test. Mice with OD were intraperitoneally injected with CY-09 or saline. The activation of microglia and astrocytes in olfactory bulb was detected by immunohistochemistry. The expression level of pyroptosis associated protein was detected by Western blot. The level of pyroptosis associated proinflammatory factor mRNA was determined by real-time PCR. SPSS 24.0 software was used for statistical analysis. Results: After the test, ovalbumin successfully established AR mice model, in which 52.5% (21/40) of them showed OD. The number of activated microglia and astroglia in olfactory bulb tissue in OD group were more than those in non-OD group (all P<0.05). Compared with the control group, the expression of NLRP3, caspase-1 and gasdermin D (GSDMD) was significantly increased in the olfactory bulb of the OD group (all P<0.05). CY-09 could significantly reduce the level of NLRP3, caspase-1, GSDMD, IL-1β and IL-18 expression, and inhibite the activation of microglia and astrocytes in the olfactory bulb tissues (all P<0.05). Conclusion: NLRP3-mediated pyroptosis is closely related to the OD associated with AR. CY-09 could improve the olfactory function in AR mice, which may be related to blocking the NLRP3-mediated pyroptosis.

Engineering prodrug nanomicelles as pyroptosis inducer for codelivery of PI3K/mTOR and CDK inhibitors to enhance antitumor immunity

Aberrant activation of oncogenic signaling pathways in tumors can promote resistance to the antitumor immune response. However, single blockade of these pathways is usually ineffective because of the complex crosstalk and feedback among oncogenic signaling pathways. The enhanced toxicity of free small molecule inhibitor combinations is considered an insurmountable barrier to their clinical applications. To circumvent this issue, we rationally designed an effective tumor microenvironment-activatable prodrug nanomicelle (PNM) for cancer therapy. PNM was engineered by integrating the PI3K/mTOR inhibitor PF-04691502 (PF) and the broad spectrum CDK inhibitor flavopiridol (Flav) into a single nanoplatform, which showed tumor-specific accumulation, activation and deep penetration in response to the high glutathione (GSH) tumoral microenvironment. The codelivery of PF and Flav could trigger gasdermin E (GSDME)-based immunogenic pyroptosis of tumor cells to elicit a robust antitumor immune response. Furthermore, the combination of PNM-induced immunogenic pyroptosis with anti-programmed cell death-1 (αPD-1) immunotherapy further boosted the antitumor effect and prolonged the survival time of mice. Collectively, these results indicated that the pyroptosis-induced nanoplatform codelivery of PI3K/mTOR and CDK inhibitors can reprogram the immunosuppressive tumor microenvironment and efficiently improve checkpoint blockade cancer immunotherapy.

Succus Bambusae， regarded as the holy medicine for the treatment of phlegm by traditional Chinese medicine experts， has the functions of clearing heat and resolving phlegm， resuscitating and relieving convulsions. In clinical practice， it is mainly used to treat phlegm-heat cough， phlegm yellow and shortness of breath， stroke with exuberant phlegm and other syndromes. The research of its processing procedure and quality standard is the key issue to realize the process modernization and quality standardization of this traditional medicine resource. On the basis of literature research， this paper conducted the herbal textual research on Succus Bambusae， sorted out its medicinal history， and compared the advantages and disadvantages of its traditional and modern preparation procedure. Based on the historical records， it is pointed out that there are still many problems in the traditional and modern processing procedure of Succus Bambusae， such as low-yield processing procedure and extensive production technology that cannot meet the requirements of large-scale green manufacturing. At present， there are a lot of literature on the comparative study of the origin， variety and processing procedure of Succus Bambusae， but most of them are limited to the chemical components， and lack of in-depth study on its pharmacodynamic substance basis and mechanism. Meanwhile， the pharmacological effects of Succus Bambusae are mostly limited to antitussive and expectorant， and few other pharmacological effects have been reported. Based on the above analysis， it is suggested that the follow-up research work can be carried out from these five aspects：①Clarifying the original source， enriching and perfecting the medicinal resources. ②Standardizing the processing procedure， establishing relevant quality standards. ③Clarifying the pharmacological mechanism， strengthening the basic research on the pharmacological effect and clinical application. ④Inheriting ancient processing， researching and developing special preparation equipment and standardizing production operation rules. ⑤Comprehensive utilization of the by-products in preparation process.
