[Objective]To investigate the effect of pantoprazole on skeletal muscle wasting in cancer cachexia and the possible mechanism.[Methods]24 male BALB/c mice were randomly divided into control group(NN),cancer cachexia group(CC),pantrop?razole treatment group(PPI). The mice in CC and PPI were inoculated subcutaneously with mouse colon adenocarcinoma C26 cells to establish a model of cancer cachexia. The mice in PPI group were gavaged with 75 mg/kg pantoprazole dissolving in physiological saline,while those in NN and CC group were gavaged with 0.1 mL/10 g physiological saline. The mice were killed 12d after treatment. The weight of gastrocnemius and tumour and the size of tumour were measured. The morphological change of skeletal muscle were evalu?ated by the method of stain with hematoxylin and eosin(H&E). The levels of IL-6 and TNF-αin serum were tested by ELISA. qRT-PCR was used to assess the expression of mRNA of Myod1 and myf5 in skeletal muscle. The protein expressions of MuRF1,MAFBx, Myod1 and myf5 were measured by Western blot.[Results]Compared with CC group ,pantoprazole can increase the weight of mice and gastrocnemius(39.8% and 24.2%,respectively),cross section area(25.4%),levels of mRNA and protein of Myod1 and myf5(P<0.05),while the levels of IL-6 and TNF-αdecreased(30.7%and 18.9%,respectively),as well as the levels of protein ex?pression of MuRF1 and MAFBx(P < 0.05).[Conclusion]Pantoprazole can attenuate the wasting of skeletal muscle,the potential mechanism may be related to the inhibition of inflammatory factors and UPS ,and up-regulation of Myod1 and myf5.

Objective: To observe the effects of follistatin (FST)on the skeletal muscle wasting of cancer cachexia mice and the expressions of Mstn, LncRNA-MALAT1 and Caspase-3, and to elucidate its associated molecular mechanisms.Methods:Thirty-two BALB/c mices were randomly assigned into:healthy control (HC) group,FST prevention (FP)group,FST treatment (FT)group and cancer cachexia (CC)group.The murine colon adenocarcinoma CT26 cells were inoculated subcutaneously into the mices in FP, FT and CC groups to establish the cancer cachexia models. The body weight, spontaneous activity and tumor growth were daily monitored.The mice in FP and FT groups were administrated with FST intraperitoneally on day 6 and 12 after inoculation.The samples were collected on day 20.The tumor and gastrocnemius weights of the mice were detected. The biochemical metabolism indexes and myofiber cross-sectional area of gastrocnemius tissue were detected.The mRNA expression levels of Mstn,Caspase-3 and LncRNA-MALAT1 were examined by Real-time PCR.The protein expression levels of Mstn and Caspase-3 were measured by Western blotting method. Results:Compared with CC group,the body weights,spontaneous activities,gastrocnemius weights and myofiber cross-sectional areas were increased (P <0.05);the serum levels of glucose,total protein and albumin of the mice in FP and FT groups were increased (P <0.05).The protein and mRNA expression levels of Mstn and Caspase-3 in gastrocnemius of the mice in CC group were significantly higher and the expression level of LncRNA-MALAT1 was significantly lower than those in HC group (P < 0.05).The mRNA and protein expression levels of Mstn and Caspase-3 in FP and FT groups were reduced and the expression level of LncRNA-MALAT1 was increased compared with CC group (P < 0.05).The prevention effect in FP group is better than FT group (P < 0.05). Conclusion:FST may alleviate the muscle wasting of the mice with cancer cachexia by inhibiting the expression of Mstn,thus upregulating the expression of LncRNA-MALAT1 which in turn to suppress the expression of Caspase-3.

An LC-MS method was established for the identification of the related substances in rivaroxaban. HPLC separation was carried out on an Inert Sustain C18 column(250 mm×4. 6 mm, 5 μm)with linear gradient elution using a mobile phase consisting of 0. 2% formic acid acetonitrile and 0. 2% formic acid aqueous solution. Rivaroxaban and its related substances could be completely separated under the established HPLC conditions. The structures of the related substances were identified by electrospray positive ESI high resolution TOF/MS and MS/MS spectra determination and elucidation, and further verified through reference substances. Fifteen related substances were detected and identified to be three related substances of starting materials, four synthetic by-products and ten degradation products. The established method is useful for the identification of the related substances in rivaroxaban. The results obtained are valuable for its manufacturing control and quality assurance.

Granulomatous lobular mastitis (GLM) is a rare form of chronic inflammatory breast disease which may be sometimes difficult to distinguish from breast cancer. The cause of GLM is unknown, but may be associated with autoimmunity, abnormal hormone levels and infection. While GLM has no specific clinical manifestations, the diagnosis is principally established by histopathology. Therapeutic options for GLM range from observation to various medical treatments, such as steroids, immunosuppressants, and antibiotics, to surgical intervention. However, there are still many difficulties in the clinical diagnosis and treatment of GLM, and there is still no unified diagnosis and treatment consensus. So, we accomplished the present review through reviewing GLM-related domestic and foreign literature, aiming to provide the basis for rational clinical diagnosis and treatment.

ObjectiveTo observe the effect of Shengxiantang （SXT） on cell senescence mediated by wingless/integrated （Wnt）3a/β-catenin pathway in rats with idiopathic pulmonary fibrosis （IPF） and reveal the possible mechanism in improving lung function of IPF rats. MethodA total of 32 SPF level SD rats were randomly divided into sham group， model group， pirfenidone group， and SXT group. The IPF rat model was established by intratracheal instillation of bleomycin （0.005 g·kg^-1）. The following day after surgery， rats in the SXT group were given the aqueous solution of SXT granules （0.78 g·kg^-1）， and the pirfenidone group was given pirfenidone suspension （0.05 g·kg^-1）. The other groups were given deionized water （10 mL·kg^-1） for 28 consecutive days. Lung tissue was collected after the lung function was measured. The pathological changes of the lung tissue were observed by hematoxylin-eosin （HE） and Masson staining， and then the Szapiel score and Ashcroft score were performed. Real-time fluorescence quantitative polymerase chain reaction （Real-time PCR） was used to detect telomere length. Western blot was applied to detect the expressions of epithelial-mesenchymal transformation （EMT） markers ［α-smooth muscle actin （α-SMA） and E-cadherin］， telomere reverse transcriptase （TRET）， aging-related proteins （p53 and p21）， senescence-associated secretory phenotype ［interleukin-6 （IL-6） and matrix metalloproteinase-1 （MMP-1）］， and key proteins of Wnt signaling pathway ［Wnt3a， glycogen synthase kinase-3β （GSK-3β）， β-catenin， Cyclin D₁， and c-Myc］. ResultCompared with those in the Sham group， peak expiratory flow （PEF） and minute ventilation volume （MV） in the model group were significantly decreased （P<0.01）， and the frequency of respiratory （f） was significantly increased （P<0.01）. The Szapiel score， Ashcroft score， and protein expression of α-SMA， p53， p21， IL-6， MMP-1， Wnt3a， GSK3β， β-catenin， Cyclin D₁， and c-Myc were increased （P<0.01）. The expressions of E-cadherin and TERT， as well as telomere length were significantly decreased （P<0.01）. Compared with those in the model group， PEF and MV in the SXT group were significantly increased （P<0.01）， while f was significantly decreased （P<0.01）. The Szapiel score， Ashcroft score， and protein expression of α-SMA， p53， p21， IL-6， MMP-1， Wnt3a， GSK3β， β-catenin， Cyclin D₁， and c-Myc were significantly decreased （P<0.05， P<0.01）. Nevertheless， the expression of E-cadherin and TERT， as well as telomere length were significantly increased （P<0.01）. ConclusionSXT presents a significant protective effect on lung function in IPF rats， and the prescription may act on the Wnt3a/β-catenin signaling pathway to regulate cell senescence induced by TERT to inhibit EMT.
