Background. XQLF (Xiaoqinglong formula) is the most commonly used prescription of traditional Chinese medicine in the treatment of asthma. XQLF combined with western medicine has been used to treat bronchial asthma in more and more cases, and good results have been achieved. Therefore, this meta‐analysis aimed to evaluate the adjuvant treatment of traditional Chinese medicine classic herbal formula XQLF with bronchial asthma in acute attack. Methods. The following electronic databases were systematically searched from inception to April 2019: PubMed, EMBASE database, Cochrane Library, China National Knowledge Infrastructure (CNKI), WanFang, VIP Database for Chinese Technical Periodicals, and China Biology Medicine (CBM). Two reviewers searched these databases and independently evaluated all the eligible articles for inclusion. Stata 14.0 was used for data synthesis and analysis. Results. A total of 33 RCTs (randomized controlled trials) including 2176 patients were enrolled. All of the patients in these studies were in the acute attack stage of asthma. We conducted subgroup analysis according to the duration of treatment, which was 14 days, 10 days, and 7 days, respectively. The overall results show that adjuvant treatment with XQLF significantly improve CER (clinical efficacy rate) (RR = 1.17; 95% CI, 1.14 to 1.21; P < 0.0001) and promote pulmonary function including FEV1 (WMD = 0.35; 95% CI, 0.27 to 0.43; P < 0.0001), PEF (SMD = 1.02; 95% CI, 0.49 to 1.55; P < 0.0001), and FVC (WMD = 0.51; 95% CI, 0.35 to 0.66; P < 0.0001). The adjuvant treatment of XQLF can also reduce serum IgE concentration (SMD = −1.39; 95% CI, 1.92 to −0.85; P < 0.0001) and serum EOS concentration at 14 days (WMD = −39.85; 95% CI, −56.20 to −23.49; P < 0.0001). Conclusion. This study finally showed that XQLF has the auxiliary effect of improving the efficiency, promoting the lung function, and reducing the serum IgE in the treatment of acute attack asthma. This trial is registered with CRD42019133549.

Background: Chronic hepatitis B is often complicated with different degrees of hepatic fibrosis, which affects the quality of life. Nucleoside analogs are recommended by almost all guidelines in the world for the treatment of chronic hepatitis B. At present, there is no specific and effective chemical and biological agents for hepatic fibrosis. In China, Chinese compound prescription combined with nucleoside analogs have been used to treat hepatic fibrosis of chronic hepatitis B patients in more and more cases, and good results have been achieved. Several Chinese compound prescriptions that have been made into proprietary Chinese medicine for the convenience of use. This article aims to systematically evaluate the efficacy and safety of Chinese medicine compounds assisting nucleoside analogs in the treatment of hepatic fibrosis in chronic hepatitis B patients. Method: The following databases will be searched from their inception to September 2019: PubMed, EMBASE, EBSCOhost, The Cochrane Library, China National Knowledge Infrastructure (CNKI), Chinese Biomedical literature Database (CBM), VIP Database, Wanfang Database. Languages are limited to Chinese and English. The study includes randomized controlled trials using Chinese compound prescription combined with entecavir and Chinese compound prescription combined with tenofovir disoproxil fumarate to treat hepatic fibrosis of chronic hepatitis B patients. The primary outcomes including effective rate and biochemical parameters (levels of hyaluronic acid, laminin, pre-type-III collagen and type IV collagen will be tested.

Hepatic pathological angiogenesis (HPA) is the key event of hepatic fibrosis (HF). Xueshisanjia powder (XSSJS), a Chinese herbal compound, is beneficial for alleviating pathological angiogenesis of hepatic tissue. The present study attempts to reveal the effect and mechanism of XSSJS via regulating miR-29b-3p/VEGFA axis against pathological angiogenesis in HF. In in vitro model, human embryonic kidney 293T cells were transfected with miR-29b-3p mimics, whereby the expression of miR-29b-3p was tested by real-time quantitative polymerase chain reaction (RT-qPCR), ensued by Luciferase assay determining the relationship between miR-29b-3p and vascular endothelial cell growth factor A (VEGFA). In addition, miR-29b-3p mimic transfected into the activated hepatic stellate cell T6 (HSC-T6). The Cell-Counting-Kit 8 (CCK8) and 5-Bromodeoxyuridine (BrdU) staining were first utilized to detect the antiproliferative efficiency of XSSJS following the XSSJS compound serum intervention, and then used to observe the expression of transforming growth factor-β (TGF-β), VEGFA, platelet-derived growth factor (PDGF) via RT-PCR, Western blot (WB), and Immunofluorescence (IF) methods. During the in vivo model, XSSJS with boil-free granules were fed to Wistar rats with liver fibrosis caused by intraperitoneal injection of pig serum followed by the transfection of miR-29b-3p adeno-associated virus (AAV). Hematoxylin–Eosin (HE) staining was used for histopathology assessment. The expression of miR-29b-3p, VEGFA, PDGF, TGF-β have been investigated in liver tissue using RT-PCR, WB, IF. The results verified that XSSJS could up-regulate miR-29b-3p and suppress the expression of VEGFA, PDGA, and TGF-β. In mechanism, miR-29b-3p primarily targeted the 3′UTR of VEGFA. In conclusion, XSSJS could modulate miR-29b-3p/VEGFA axis to inhibit the pathological angiogenesis of HF.

Myopathy encompasses a group of diseases characterized by abnormalities in both muscle function and structure. However, the underlying regulatory mechanisms of newly formed myofiber development remain poorly defined. No promising therapeutic approach has been developed, but numerous medication options are available to alleviate symptoms. Our previous studies demonstrated that adenosine kinase (ADK) is critical in regulating adenosine metabolism, pathological angiogenesis, pathological vascular remodeling, and vascular inflammatory diseases. Adenosine dynamically distributes between extracellular and intracellular, and adenosine concentration regulates ADK expression. However, the mechanism by which adenosine triggers an ADK-dependent intracellular signaling pathway to regulate skeletal muscle regeneration is not well defined. This study aimed to evaluate whether the adenosine-induced intracellular signaling pathway is involved in regulating myopathy, and how it regulates the development of newly formed myofibers. In this study, an intramuscular injection of cardiotoxin was used to induce a skeletal muscle injury model; satellite cells and C2C12 cells were employed. Whether adenosine regulates satellite cell activity, new myofiber formation and differentiation, as well as fusion of myofibers, were determined by H&E staining, BrdU incorporation assay, and spheroid sprouting assay. Interaction between ADK and PFKFB3 was evaluated by IF staining, PPI network analysis, molecular docking simulation, and CO-immunoprecipitation assay. The results demonstrated that adenosine dynamically distributes between extracellular and intracellular through concentrative nucleoside transports or equilibrative nucleoside transporters, and it rapidly induces an ADK-dependent intracellular signaling pathway, which interacts with PFKFB3-mediated glycolytic metabolism to promote satellite cell activity, new myofiber formation, differentiation, and fusion, and eventually enhances skeletal muscle regeneration after injury stress. The remarkable endogenous regeneration capacity of skeletal muscle, which is regulated by adenosine-triggered intracellular signaling, presents a promising therapeutic strategy for treating muscle trauma and muscular dystrophies.
