Objective To noninvasively predict isocitrate dehydrogenase(IDH)status of glioma via combining imaging and clini-cal features before surgery,so as to provide basis for individualized clinical treatment decision.Methods A total of 47 patients with glioma confirmed by pathological and molecular genetic tests were included,including 20 with IDH mutant type and 27 with IDH wild type.After diffusion tensor imaging(DTI)scanning,fractional anisotropy(FA)and mean diffusivity(MD)values of tumor paren-chyma were calculated.Combining DTI parameters with MRI morphological features of tumor,blood neutrophil/lymphocyte ratio(NLR)and patient's age,binary logistic regression model was established to effectively predict IDH status of glioma patients before surgery.Results There were significant differences in FAmean/FANAWM,MDmin,NLR,tumor location and age between IDH mutant type and IDH wild type groups(P<0.05).The binary logistic regression model concluding,FAmean/FANAWM,MDmin,cystic degeneration,NLR and age,predicted IDH status of glioma with area under the curve(AUC)of 0.961 and 95%confidence interval(CI)of 0.914-1.00.Conclusion The regression model established via combining DTI,MRI morphological features and blood NLR has great performance in classifying IDH status of glioma,and can help predict IDH status noninvasively before surgery,so as to assist clinical individualized treatment.

OBJECTIVE To explore the mechanisms of the flavonoids from new "Zhe Eight Flavors" Quzhou Fructus Aurantii(PTFC) against hepatocellular carcinoma based on the prediction of network pharmacology and experimental verification. METHODS From TCMSP, TCMID, ETCM, BATMAN-TCM and SwissTargetPrediction databases, the potential target proteins of PTFC, including naringin, narirutin and neohesperidin were collected. Based on the GeneCards, CTD, Disgenet, and OMIM databases, a set of target proteins for hepatocellular carcinoma was constructed. Taking the intersection of potential target proteins of PTFC and target proteins of hepatocellular carcinoma, key target proteins were obtained and a protein-protein interaction network was established. Besides, GO function and KEGG pathway enrichment analysis on the core target proteins was performed and a Compounds-Targets-Pathways-Disease network was constructed. Through proliferation, cloning, wound healing, and migration experiments, the effects of PTFC on the viability of HepG2 liver cancer cells were analyzed. Using fluorescence probe staining the impacts of PTFC on the mitochondrial membrane potential and apoptosis of HepG2 were observed. Finally, the validation of the regulatory effect of PTFC on the key predicted target PRKCA were carried out through RT-qPCR. RESULTS Based on network pharmacology, a total of 217 potential target proteins for PTFC were screened, with 59 intersecting target proteins related to diseases, including ALB, ESR1, PRKCA, and others. GO functional and KEGG pathway enrichment analysis revealed that the PTFC target proteins were involved in 193 biological processes and 13 cancer-related signaling pathways. Experimental results demonstrated that PTFC could impact the proliferation, cloning, wound healing, and migration abilities of liver cancer cells, leading to a decrease in mitochondrial membrane potential and promoting cell apoptosis. The results of RT-qPCR confirmed a significant downregulation of PRKCA expression by PTFC, validating the predictions made by network pharmacology analysis. CONCLUSION This study has revealed the potential molecular mechanism of PTFC treating hepatocellular carcinoma via the PRKCA target, laying the foundation for clinical application of PTFC.

ObjectiveTo explore the mechanism of Shenqi Gualou Xiebai Banxia Decoction （参芪瓜蒌薤白半夏汤， SGXBD） in the treatment of atherosclerosis. MethodsThirty Apolipoprotein E gene knockout （ApoE^-/-） mice were randomly divided into five groups： model group， rosuvastatin group， low-， moderate-， and high-dose SGXBD， with six mice in each group. They were fed a high-fat diet to prepare for atherosclerosis model. Another six C57BL/6J wild-type mice were set as the blank group. After modeling， the low-， moderate-， and high-dose SGXBD groups were gavaged with 6.46， 12.92， and 25.84 g/（kg·d） of SGXBD， respectively. The rosuvastatin group was given 1.55 mg/（kg·d） of rosuvastatin tablets by gavage. The blank group and model group were given 0.5 ml saline by gavage. After four weeks， the total cholesterol （TC）， triglyceride （TG）， low-density lipoprotein cholesterol （LDL-C）， and high-density lipoprotein cholesterol （HDL-C） in the serum of each group were detected， as well as TC and TG in the liver. The serum bile acid level was detected by enzyme cycling colorimetry. The mRNA and protein expression of peroxisome proliferator-activated receptor γ （PPARγ）， sterol regulatory element-binding protein 2 （SREBP2）， 3-hydroxy-3-methylglutaryl-CoA reductase （HMGCR）， and cholesterol 7α-hydroxylase （CYP7A1） in the liver were detected by real-time RT-PCR and Western blot. ResultsCompared with the blank group， the model group showed significant increases in serum TG， TC， and LDL-C levels， and significant decreases in HDL-C and bile acid levels； the levels of TG and TC in the liver， as well as the expression of SREBP2 and HMGCR proteins and mRNA in the liver significantly increased， while the expression of PPARγ and CYP7A1 proteins and mRNA significantly decreased （all P＜0.01）. Compared with the model group， the rosuvastatin group and high-dose SGXBD group showed significant decreases in serum TG， TC， and LDL-C levels and liver TG and TC levels， and significant increases in bile acid levels； the expression of PPARγ and CYP7A1 proteins and mRNA increased， while the expression of SREBP2 and HMGCR proteins and mRNA decreased； the low-dose SGXBD group showed significant decreases in serum TC and LDL-C levels and liver TC level （P＜0.05 or P＜0.01）. Compared with the rosuvastatin group， the low-dose SGXBD group had a significantly higher liver TC level， while the high-dose SGXBD group had a significantly lower liver TC level， CYP7A1 mRNA level， and PPARγ protein expression level， and a significantly higher SREBP2 protein expression level （P＜0.05 or P＜0.01）. Compared with the low- and moderate-dose groups， the high-dose SGXBD group had significantly lower serum TG and liver TC levels （P＜0.05）. ConclusionSGXBD may improve blood lipid levels and exhibit anti-atherosclerotic effects by regulating the protein level of PPARγ and simultaneously affecting the synthesis of liver cholesterol and the conversion of cholesterol to bile acids.

Although somatic cells can be reprogrammed to pluripotent stem cells (PSCs) with pure chemicals, authentic pluripotency of chemically induced pluripotent stem cells (CiPSCs) has never been achieved through tetraploid complementation assay. Spontaneous reprogramming of spermatogonial stem cells (SSCs) was another non-transgenic way to obtain PSCs, but this process lacks mechanistic explanation. Here, we reconstructed the trajectory of mouse SSC reprogramming and developed a five-chemical combination, boosting the reprogramming efficiency by nearly 80- to 100-folds. More importantly, chemical induced germline-derived PSCs (5C-gPSCs), but not gPSCs and chemical induced pluripotent stem cells, had authentic pluripotency, as determined by tetraploid complementation. Mechanistically, SSCs traversed through an inverted pathway of in vivo germ cell development, exhibiting the expression signatures and DNA methylation dynamics from spermatogonia to primordial germ cells and further to epiblasts. Besides, SSC-specific imprinting control regions switched from biallelic methylated states to monoallelic methylated states by imprinting demethylation and then re-methylation on one of the two alleles in 5C-gPSCs, which was apparently distinct with the imprinting reprogramming in vivo as DNA methylation simultaneously occurred on both alleles. Our work sheds light on the unique regulatory network underpinning SSC reprogramming, providing insights to understand generic mechanisms for cell-fate decision and epigenetic-related disorders in regenerative medicine.

Idiopathic pulmonary fibrosis (IPF) is a progressive disease with unknown etiology and limited therapeutic options. Activation of fibroblasts is a prominent feature of pulmonary fibrosis. Here we report that lncRNA DACH1 (dachshund homolog 1) is downregulated in the lungs of IPF patients and in an experimental mouse model of lung fibrosis. LncDACH1 knockout mice develop spontaneous pulmonary fibrosis, whereas overexpression of LncDACH1 attenuated TGF-β1-induced aberrant activation, collagen deposition and differentiation of mouse lung fibroblasts. Similarly, forced expression of LncDACH1 not only prevented bleomycin (BLM)-induced lung fibrosis, but also reversed established lung fibrosis in a BLM model. Mechanistically, LncDACH1 binding to the serine/arginine-rich splicing factor 1 (SRSF1) protein decreases its activity and inhibits the accumulation of Ctnnb1. Enhanced expression of SRSF1 blocked the anti-fibrotic effect of LncDACH1 in lung fibroblasts. Furthermore, loss of LncDACH1 promoted proliferation, differentiation, and extracellular matrix (ECM) deposition in mouse lung fibroblasts, whereas such effects were abolished by silencing of Ctnnb1. In addition, a conserved fragment of LncDACH1 alleviated hyperproliferation, ECM deposition and differentiation of MRC-5 cells driven by TGF-β1. Collectively, LncDACH1 inhibits lung fibrosis by interacting with SRSF1 to suppress CTNNB1 accumulation, suggesting that LncDACH1 might be a potential therapeutic target for pulmonary fibrosis.

Objective:To investigate the clinicopathological features, treatment programs and prognosis of patients with primary diffuse large B-cell lymphoma (DLBCL) in cavernous sinus.Methods:The clinical data of a patient with primary DLBCL in cavernous sinus who were admitted to Wuhan No.1 Hospital in December 2020 were retrospectively analyzed, and the relevant literature was reviewed.Results:The patient was a 63-year-old female who underwent resection of the cavernous sinus lesion, and the pathological diagnosis was DLBCL. The patient received 6 courses of R-CHOP regimen chemotherapy, lumbar puncture + intrathecal injection of chemotherapy drugs, and twice additional rituximab immunochemotherapy, and no tumor cells were found in the results of liquid-based thin layer cytology for cerebrospinal fluid exfoliated cells; twice magnetic resonance imaging (MRI) re-examination after the operation showed no recurrence and adjacent metastasis of the tumor. The patient's symptoms were significantly improved without residual neurological sequelae.Conclusions:Primary DLBCL in cavernous sinus is rare in clinical practice, early diagnosis is crucial for the prognosis of patients, and different protein expression may indicate the prognosis. Biopsy, complete resection of the tumor under the premise of preserving important anatomical structures and functions, and standardized chemotherapy combined with intrathecal injection local chemotherapy can effectively prolong the survival time of patients and improve the quality of life.
