Objective To investigate the effects of socioeconomic factors on the prognosis of multiple myeloma (MM) patients and construct a prediction model for evaluating myeloma-specific survival (MSS) rates. Methods A total of 32625 patients diagnosed with MM between January 2007 and December 2016 were included through the SEER database. Cox regression model was used to analyze the predictive indicators of MSS. The results of the multivariate subgroup analysis were presented as forest plots. The significant factors identified in the multivariate Cox analysis were used to construct a nomogram. The predictive performance of the nomogram was assessed using the AUC and calibration plots. A nomogram score-based risk stratification system was constructed using a restricted cubic spline. Results Patients were divided into five groups according to their socioeconomic status (SES). Groups with higher SES had relatively higher proportions of those part of the White, insured, married, and urban populations. Age, gender, race, marital status, insurance status, and SES were independent prognostic factors of MSS (all

Objective: To investigate the effect of C-phycocyanin (C-PC) on the epithelial-mesenchymal transition (EMT) of cervical cancer Caski cells induced by transforming growth factor beta1 (TGF-β1). Methods: According to different treatment methods, Caski cells were divided into three groups: 10 ng/ml TGF-β1 treatment group, 10 ng/ml TGF-β1+300 μg/ml C-PC co-treatment group and control group (untreated). After 24 h of treatment, the morphological changes of Caski cells were observed, and the effects of TGF-β1 and C-PC on the migration and invasion of Caski cells were detected by Scratch test and Transwell test, respectively. Western blotting was used to detect the effect of C-PC on the expression of epithelial phenotypic marker protein E-cadherin and stromal phenotypic marker protein N-cadherin in TGF-β1-induced Caski cells, and qPCR was used to detect the mRNA expressions of EMT related factors Snail, Zeb1 and Twist. Results: Caski cells in the TGF-β1 treatment group lost the characteristics of the original epithelial phenotype, while the cells in the TGF-β1+C-PC co-treatment group maintained the characteristics of normal epithelial phenotype; the migration rate ([60.0±1.4]% vs [33.5±2.2]%, [40.0±2.8]%, both P<0.05) and the number of invasive transmembrane cells ([108.2±6.2] vs [25.2±3.1], [39.8±5.4], both P<0.01]) of Caski cells in the TGF- β1 treatment group were significantly higher than those in the co-treatment group and the control group. Compared with the control group, the expression of E-cadherin in Caski cells treated with TGF-β1 decreased significantly (P<0.05), while the mRNA expressions of Twist, Snail and Zeb1 increased significantly (all P<0.05); However, co-treatment with C-PC reversed above changes (P<0.05 or P<0.01), and significantly decreased the protein expression level of N-cadherin (P< 0.05). Conclusion: C-PC treatment can inhibit the invasion and metastasis ability of Caski cells induced by TGF-β1 and further affects the EMT process. The mechanism may be related to the decrease of mRNAexpressions of Twist, Snail and Zeb1 by C-PC treatment. ·

AIM:Bone morphogenetic protein 7(BMP7)reduces the expression of Yes-related protein 1(YAP1)by down-regulating Ajuba level and decreasing extracellular matrix(ECM)deposition.This study aimed to inves-tigate the influence of these factors on modifying the degree of renal fibrosis in rats with diabetic nephropathy.METH-ODS:Eighteen Sprague-Dawley(SD)rats were randomly divided into three groups:the normal control(NC)group,the diabetes mellitus(DM)group,and the DM group treated with BMP7 overexpressing adeno-associated virus(DM+rAAV-BMP7).Each group consisted of six rats.Diabetic kidney disease(DKD)was established in the DM and DM+rAAV-BMP7 groups by injecting 55 mg/kg streptozotocin(STZ)via the tail vein.NRK-52E cells were divided into three groups:the normal glucose(NG)group,the high glucose(HG)group,and the high glucose group treated with recombinant hu-man BMP7(HG+rhBMP7)group.Pathological changes in renal tissues were observed using hematoxylin and eosin(HE)and Sirius red staining.Immunohistochemical staining was performed to examine the expression sites of Ajuba and YAP1 in the renal cortex.Western blot analysis was conducted to determine the expression levels of BMP7,Ajuba,YAP1,colla-gen type Ⅲ(Col-Ⅲ),and fibronectin(FN)in the rat renal cortex and NRK-52E cells.RT-qPCR was used to measure the mRNA levels of Ajuba and YAP1 in the rat renal cortex.RESULTS:Biochemical indices revealed significantly ele-vated levels of blood glucose,serum creatinine,triglycerides,total cholesterol,and 24-hour urinary protein in the DM group compared to the NC group(P<0.05).In the DM+rAAV-BMP7 group,the levels of serum creatinine,24-hour uri-nary protein,triglycerides,and total cholesterol were lower than those in the DM group(P<0.05).Pathological staining demonstrated that the renal interstitium of the DM group exhibited inflammatory cell infiltration,fibrous tissue,collagen fi-ber deposition,disordered renal tubule arrangement,atrophy,and vacuolar degeneration,which were ameliorated in the DM+rAAV-BMP7 group.Immunohistochemistry revealed that Ajuba and YAP1 were mainly expressed in the cytoplasm and nucleus,with high expression in the cytoplasm of the DM group,which was significantly decreased in the DM+rAAV-BMP7 group.Western blot results indicated that the protein levels of FN,Col-Ⅲ,Ajuba,and YAP1 were up-regulated in the DM and the HG groups(P<0.05),but significantly down-regulated in the DM+rAAV-BMP7 group(P<0.05).RT-qP-CR results demonstrated that the mRNA levels of Ajuba and YAP1 were higher in the DM group and significantly lower in the DM+rAAV-BMP7 group(P<0.05).CONCLUSION:The overexpression of BMP7 can ameliorate renal fibrosis in rats with DKD.This effect is likely mediated by the down-regulation of Ajuba,reduction of YAP1 expression,and subse-quent inhibition of ECM deposition.

OBJECTIVE To study the pharmacological basis of Schisandra chinensis in the treatment of allergic asthma. METHODS The common components of 10 batches of S. chinensis from different habitats were analyzed by UPLC-Q-TOF-MS/MS. Furthermore, the allergic asthma model was established by intraperitoneal injection of ovalbumin (OVA) and aluminum hydroxide for stimulation combined with atomization exitation; general behavioral observation and the contents of interferon γ (IFN-γ), interleukin-4 (IL-4) and immunoglobulin E (IgE) in serum were taken as criteria for evaluating the therapeutic effect of S. chinensis from different habitats in the treatment of allergic asthma. Correlation coefficients between common peak area and efficacy evaluation index of each batch of medicinal material were analyzed through grey correlation degree and Pearson correlation analysis. RESULTS A total of 21 common components were identified in 10 batches of S. chinensis from different habitats. After administration of S. chinensis, symptoms such as shortness of breath, sneezing and curling of rats were alleviated. In addition, the content of IFN-γ was significantly increased while the contents of IL-4 and IgE in serum were distinctly decreased (P<0.01). Grey correlation analysis showed that 11 common components had high correlation coefficients with IFN-γ, IL-4 and IgE (rˉ>0.8). Pearson correlation analysis showed that 8 components were significantly positively correlated with the content of IFN-γ (P< 0.05), and 9, 8 components were significantly negatively correlated with the content of IL-4 and IgE (P<0.05). Based on the results of grey correlation degree and Pearson correlation analysis, 7 components such as peak 3, 4, 6, 7, 9, 19 and 20, were highly related to S. chinensis in the treatment of allergic asthma. CONCLUSIONS Schisandrol A, schisandrin B, schisandrin C, gomisin M2, gomisin J, pregomisin and angeloylgomisin H are the potential pharmacodynamic substance basis of S. chinensis in the treatment of allergic asthma.

The current document is based on a consensus reached by a panel of experts from the Chinese Society of Allergy and the Chinese Society of Otorhinolaryngology-Head and Neck Surgery, Rhinology Group. Chronic rhinosinusitis (CRS) affects approximately 8% of Chinese adults. The inflammatory and remodeling mechanisms of CRS in the Chinese population differ from those observed in the populations of European descent. Recently, precision medicine has been used to treat inflammation by targeting key biomarkers that are involved in the process. However, there are no CRS guidelines or a consensus available from China that can be shared with the international academia. The guidelines presented in this paper cover the epidemiology, economic burden, genetics and epigenetics, mechanisms, phenotypes and endotypes, diagnosis and differential diagnosis, management, and the current status of CRS in China. These guidelines—with a focus on China—will improve the abilities of clinical and medical staff during the treatment of CRS. Additionally, they will help international agencies in improving the verification of CRS endotypes, mapping of eosinophilic shifts, the identification of suitable biomarkers for endotyping, and predicting responses to therapies. In conclusion, these guidelines will help select therapies, such as pharmacotherapy, surgical approaches and innovative biotherapeutics, which are tailored to each of the individual CRS endotypes.
