To conduct a meta-analysis of the effectiveness and safety of (TwHF) extracts for the treatment of rheumatoid arthritis (RA). A systematic literature search was conducted in PubMed, EMBASE, Cochrane, Medline, CNKI, SinoMed and WanFang Library till 12 July 2017. All included studies were analyzed with the use of the Review Manager 5.2 software according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) Statement protocol. Fourteen randomized controlled trials (RCTs) were identified. TwHF extracts provided a statistically significant improvement in grip strength (GS), swelling joint count (SJC) and morning stiffness (MS) compared with placebo ( < 0.001). The meta-analysis showed significant differences between TwHF extract-treated group and the DMARDs group in GS, MS, C-reactive protein (CRP), and tender joint count (TJC) ( < 0.05), aside from ESR and SJC ( > 0.05). The pooled results also displayed significant differences between the combination of TwHF extracts with DMARDs and the DMARDs alone group in ESR, CRP, SJC, and TJC ( ≤ 0.05). For the safety analysis, two trials favored TwHF extract-treatment and one trial favored non-TWHF extract-treatment in AEs ( < 0.05). Eleven trials showed no statistically significant differences between TwHF extract-treated group and the DMARDs group ( > 0.05). The findings of this systematic review with meta-analysis indicate that TwHF extracts provides statistically significant and clinically important improvement in RA symptoms and has an acceptable safety profile.

Mifepristone (Mif), an effective synthetic steroidal antiprogesterone drug, is widely used for medical abortion and pregnancy prevention. Due to its anti-glucocorticoid effect, high-dose Mif is also used to treat Cushing’s syndrome. Mif was reported to active pregnane X receptor (PXR) in vitro and PXR can induce hepatomegaly via activation and interaction with yes-associated protein (YAP) pathway. High-dose Mif was reported to induce hepatomegaly in rats and mice, but the underlying mechanism remains unclear. Here, the role of PXR was studied in Mif-induced hepatomegaly in C57BL/6 mice and Pxr -knockout mice. The results demonstrated that high-dose Mif (100 mg · kg −1  · d −1 , i.p .) treatment for 5 days significantly induced hepatomegaly with enlarged hepatocytes and promoted proliferation, but low dose of Mif (5 mg · kg −1  · d −1 , i.p .) cannot induce hepatomegaly. The dual-luciferase reporter gene assays showed that Mif can activate human PXR in a concentration-dependent manner. In addition, Mif could promote nuclear translocation of PXR and YAP, and significantly induced the expression of PXR, YAP, and their target proteins such as CYP3A11, CYP2B10, UGT1A1, ANKRD, and CTGF. However, Mif (100 mg · kg −1  · d −1 , i.p .) failed to induce hepatomegaly in Pxr -knockout mice, as well as hepatocyte enlargement and proliferation, further indicating that Mif-induced hepatomegaly is PXR-dependent. In summary, this study demonstrated that PXR-mediated Mif-induced hepatomegaly in mice probably via activation of YAP pathway. This study provides new insights in Mif-induced hepatomegaly, and provides novel evidence on the crucial function of PXR in liver enlargement and regeneration.

Vacuolar protein sorting 33B (VPS33B) is important for intracellular vesicular trafficking process and protein interactions, which is closely associated with the arthrogryposis, renal dysfunction, and cholestasis syndrome. Our previous study has shown a crucial role of Vps33b in regulating metabolisms of bile acids and lipids in hepatic Vps33b deficiency mice with normal chow, but it remains unknown whether VPS33B could contribute to cholestatic liver injury. In this study we investigated the effects of hepatic Vps33b deficiency on bile acid metabolism and liver function in intrahepatic cholestatic mice. Cholestasis was induced in Vps33b hepatic knockout and wild-type male mice by feeding 1% CA chow diet for 5 consecutive days. We showed that compared with the wild-type mice, hepatic Vps33b deficiency greatly exacerbated CA-induced cholestatic liver injury as shown in markedly increased serum ALT, AST, and ALP activities, serum levels of total bilirubin, and total bile acid, as well as severe hepatocytes necrosis and inflammatory infiltration. Target metabolomics analysis revealed that hepatic Vps33b deficiency caused abnormal profiles of bile acids in cholestasis mice, evidenced by the upregulation of conjugated bile acids in serum, liver, and bile. We further demonstrated that the metabolomics alternation was accompanied by gene expression changes in bile acid metabolizing enzymes and transporters including Cyp3a11 , Ugt1a1 , Ntcp , Oatp1b1 , Bsep , and Mrp2 . Overall, these results suggest a crucial role of hepatic Vps33b deficiency in exacerbating cholestasis and liver injury, which is associated with the altered metabolism of bile acids.

Epilepsy is a clinical syndrome caused by the highly synchronized abnormal discharge of brain neurons. It has the characteristics of paroxysmal, transient, repetitive, and stereotyped. Circular RNAs (circRNAs) are a recently discovered type of noncoding RNA with diverse cellular functions related to their excellent stability; additionally, some circRNAs can bind and regulate microRNAs (miRNAs). The present study was designed to screen the differentially expressed circRNA in an acute seizure model of epilepsy in mice, analyze the related miRNA and mRNA, and study their participating functions and enrichment pathways. In order to obtain the differential expression of circRNA in epilepsy and infer their function, we used next‐generation sequencing and found significantly different transcripts. CIRI (circRNA identifier) software was used to predict circRNA from the hippocampus cDNA, EdgeR was applied for the differential circRNA analysis between samples, and Cytoscape 3.7.2 software was used to draw the network diagram. A total of 10,388 differentially expressed circRNAs were identified, of which 34 were upregulated and 66 were downregulated. Among them, mm9_circ_008777 and mm9_circ_004424 were the key upregulated genes, and their expression in the epilepsy group was verified using Quantitative real‐time PCR (QPCR). The analysis indicated that the extracted gene ontology terms and Kyoto Encyclopedia of Genes and Genomes pathways were closely related to several epilepsy‐associated processes. This study determined that mm9_circ_008777 and mm9_circ_004424 are potential biomarkers of epilepsy, which play important roles in epilepsy‐related pathways. These results could help improve the understanding of the biological mechanisms of circRNAs and epilepsy treatments.

O. elatus Nakai is a traditional medicine that has been confirmed to exert effective antioxidant and anti-inflammatory functions, and is used for the treatment of different disorders. However, its potential beneficial effects on drug induced hepatotoxicity and relevant molecular mechanisms remain unclear. This study investigated the protective effect and further elucidated the mechanisms of action of O. elatus on liver protection. O. elatus chlorogenic acids-enriched fraction (OEB), which included chlorogenic acid and isochlorogenic acid A, were identified by HPLC-MS/MS. OEB was administrated orally daily for seven consecutive days, followed by a single intraperitoneal injection of an overdose of APAP after the final OEB administration. The effects of OEB on immune cells in mice liver were analyzed using flow cytometry. APAP metabolite content in serum was detected using HPLC-MS/MS in order to investigate whether OEB affects CYP450 activities. The intestinal content samples were processed for 16 s microbiota sequencing. Results demonstrated that OEB decreased alanine aminotransferase, aspartate aminotransferase contents, affected the metabolism of APAP, and decreased the concentrates of APAP, APAP-CYS and APAP-NAC by inhibiting CYP2E1 and CYP3A11 activity. Furthermore, OEB pretreatment regulated lipid metabolism by affecting the peroxisome proliferator-activated receptors (PPAR) signaling pathway in mice and also increased the abundance of Akkermansia and Parabacteroides . This study indicated that OEB is a potential drug candidate for treating hepatotoxicity because of its ability to affect drug metabolism and regulate lipid metabolism.

Context • Ankylosing spondylitis (AS) is a refractory rheumatic disease, characterized by sacroiliitis and structural damage, and over decades, it can lead to joint fusion, frequently followed by significant spinal deformity and disability. However, to date, no method has been found to be effective in relieving or blocking structural damage to joints. Objective • The study intended to show that a decoction of Bushen-Qiangdu-Zhilv (BQZ), a therapy used in traditional Chinese medicine (TCM), can provide an alternative treatment for AS patients. Design • The research team performed a case study. Setting • The study was conducted at Guangdong Provincial Hospital of TCM in Guangzhou, China. Participant • The case study involved a 33-y-old male patient with active AS who visited the research team's clinic. Intervention • The patient took the BQZ orally 2 ×/d at 30 min after breakfast and 30 min after dinner. The patient returned to the clinic for consultation monthly. The patient took 2 servings/d for 10 mo and then received continuous BQZ treatment of the maintenance dosage for a period of approximately 3 y until December 2013. The maintenance dosage of BQZ was 3 or 4 decoctions per wk. Outcome Measures • The study used a number of measurements to evaluate the outcomes of treatment: (1) disease activity-the Bath Ankylosing Spondylitis Disease Activity Index (BASDAI); (2) functional condition-the Bath Ankylosing Spondylitis Functional Index (BASFI); (3) inflammation-ratings of morning stiffness and night pain, serum C-reactive protein (CRP) concentration measured by means of particle-enhanced immunonephelometry, and erythrocyte sedimentation rate (ESR) value as detected using the Westergren method; (4) spinal mobility-the Bath Ankylosing Spondylitis Metrology Index (BASMI); and (5) global assessments by patient and physician. Results • The participant showed improvements in inflammatory symptoms and recovery from structural damage after receiving the TCM therapy for 3 y. Conclusions • The study has shown that the long-term use of BQZ not only can lead to an improvement in inflammatory symptoms and quality of life but also can help to restore function after structural damage in AS patients.

In early mammalian embryos, the genome is transcriptionally quiescent until the zygotic genome activation （ZGA） which occurs 2-3 days after fertilization. Despite a long-standing effort, maternal transcription factors regulating this crucial developmental event remain largely elusive. Here, using maternal and paternal mouse models of Yapl deletion, we show that maternally accumulated yes-associated protein （YAP） in oocyte is essential for ZGA. Maternal Yapl-knoekout embryos exhibit a prolonged two-cell stage and develop into the four-cell stage at a much slower pace than the wild-type controls. Transcriptome analyses identify YAP target genes in early blastomeres; two of which, Rp113 and Rrm2, are required to mediate maternal YAP＇s effect in conferring developmental competence on preim- plantation embryos. Furthermore, the physiological YAP activator, lysophosphatidic acid, can substantially improve early development of wild-type, but not maternal Yapl-knockout embryos in both oviduct and culture. These obser- vations provide insights into the mechanisms of ZGA, and suggest potentials of YAP activators in improving the de- velopmental competence of cultured embryos in assisted human reproduction and animal biotechnology.

Bushen-Qiangdu-Zhilv (BQZ) decoction is a traditional Chinese medicinal compound widely used for treating ankylosing spondylitis (AS). However, the mechanisms underlying effects of BQZ remain largely unknown. Osteoblast differentiation of fibroblasts plays an important role in heterotopic ossification (HO) of AS, and connexin 43 (Cx43) is crucially involved in the osteoblast differentiation of fibroblasts. The aim of the present study was to evaluate the effects of BQZ on the osteogenic differentiation of fibroblasts by regulating Cx43. Rat fibroblasts were treated with freeze-dried powder of BQZ, in the presence or absence of recombinant human bone morphogenetic protein-2 (rhBMP-2). MTS assays were performed to examine the inhibitory effects of BQZ on fibroblast proliferation. Western blot assays were conducted to detect the protein expression of core-binding factor alpha 1 (Cbfα1), Cx43 and phosphorylated Cx43 (pCx43). BQZ appeared to inhibit fibroblast proliferation in a dose-dependent manner. Furthermore, the expression of Cbfα1 and Cx43/pCx43 was significantly suppressed by BQZ, with or without rhBMP-2 stimulation. Therefore, the present results indicate that BQZ may exert an anti-AS effect by suppressing the osteogenic differentiation of fibroblasts via Cx43 regulation.
