ObjectiveTo assess the therapeutic effectiveness and safety of the traditional Chinese medicine compound Shenlong decoction in addressing the symptoms of pulmonary deficiency and stasis in patients with idiopathic pulmonary fibrosis （IPF）. MethodsSixty eligible patients with lung deficiency and collateral stasis syndrome of IPF were randomly assigned to the observation （30 patients） and control groups （30 patients）. All patients underwent standard Western medical therapy. Additionally，the observation group received Shenlong decoction granules，while the control group received a placebo. Both treatments were packaged in four doses of 10.5 g each，taken twice daily for three months. The indexes of the patients during the treatment cycle were observed，and the main indexes include traditional Chinese medicine （TCM） syndrome scores and 6 min walk test （6MWT）. The secondary indexes include pulmonary function test ［actual value/expected value of total lung volume （TLC%），actual value/expected value of vital capacity（FVC%），actual/predicted diffusing capacity of the lung for carbon monoxide（DLCO%），actual/predicted forced expiratory volume in one second （FEV₁%），and FEV₁/ forced vital capacity （FVC）］，blood gas analysis ［arterial blood diathesis partial pressure of oxygen （PaO₂），partial pressure of carbon dioxide （PaCO₂），and arterial oxygen saturation （SaO₂）］，serum inflammatory factors ［transforming growth factor-β₁ （TGF-β₁），interleukin-4 （IL-4），interleukin-13 （IL-13），interleukin-12 （IL-12），and gamma-interferon （IFN-γ）］，and quality of survival evaluation ［St George's Respiratory Questionnaire （SGRQ） score］. The patients' clinical manifestations were determined at the end of the treatment， and the occurrence of adverse events was recorded. ResultsA total of 53 patients completed the study，comprising 27 in the control group and 26 in the observation group. Upon completion of the treatment period，the control group achieved a total effective rate of 33.33% （9/27），whereas the observation group demonstrated a total effective rate of 53.85% （14/26），which was statistically superior to the control group （χ²=4.034，P<0.05）. After the treatment，the TCM syndrome scores，6MWT，DLCO%，FEV₁%，PaO₂，PaCO₂，TGF-β₁，IL-4，IL-13，IL-12，and IFN-γ in the two groups were all significantly improved （P<0.01）. Compared with those in the control group after treatment at the same period，the TCM syndrome scores，6MWT，PaO₂，and PaCO₂ were significantly improved in the observation group after 60 days and 90 days of medication （P<0.01）. Three months after the end of medication，the SGRQ score in the observation group showed significant improvement when compared to that in the control group （P<0.05），and no severe adverse events were reported during the follow-up period. ConclusionCompound Shenlong decoction can alleviate clinical symptoms such as shortness of breath and wheezing in patients with lung deficiency and collateral stasis syndrome of IPF，enhance exercise tolerance，improve the quality of life，and have certain potential advantages in improving pulmonary function.

In order to establish the isolation,culture and identification method of cow bone marrow-derived macrophages,three different media(RPMI-1640,DMEM,DMEM/F12)were added with 20％fetal bovine serum(FBS),2.4％chlorine-streptomycin,1.2％glutamine(Gln),and M-CSF(20 ng/mL),respectively,to induce the monocytes extracted from the bone marrow of dairy cows to become macrophages.The induced M0 macrophages were polarized into M1-type macrophages by adding lipopolysaccharide(LPS).The morphology of macrophages was observed by optical mi-croscope at day 1,4 and 7,and the differences of differentiated macrophages between the three media were compared.The effects of prostaglandin D2(PGD2)-DP2 receptor pathway on the secre-tion of cytokines(IL-6,TNF-α)induced by Escherichia coli and phagocytosis of macrophages were also investigated.The results showed that the morphological changes of cells cultured in the medium of RPMI-1640 were the most obvious and the number was large.A large number of char-acteristic markers of mononuclear macrophages were detected(M0 markers:CD1 1b,CD14;M1 markers:CD11b,CD80)expression,M0 and M1 macrophage purity were 79.9％and 93.5％,re-spectively.COX-2 and H-PGDS gene expressions were significantly increased in E.coli group com-pared with the blank control group.The secretion of PGD2also increased significantly(P＜0.000 1).DP2 receptor inhibitors(CAY10471,CAY10595)could significantly inhibit the secretion of E.coli in-duced pro-inflammatory cytokines(IL-6,TNF-α)and significantly enhance the killing effect of macrophages on E.coli.The above results showed that the induced cells had the characteristic mor-phology and immunophenotype of macrophages.E.coli can induce the production of PGD2 in mac-rophages,and the PGD2-DP2 pathway regulates the secretion of cytokines in E.coli infected macro-phages.

OBJECTIVE To explore the role of Yes-associated protein(YAP)in epidermal stem cell(EPSC)differentiation after ionizing radiation(IR).METHODS ① A punch was used to induce skin injuries on the back of mice.The IR group received localized irradiation with 60 Co γ-rays,while the normal control group did not.Samples were collected at 0,1,3,6,9,and 12 d for RNA and protein extraction.Western blotting was used to detect changes in YAP protein expressions during wound healing.Real-time quantitative polymerase chain reaction(RT-qPCR)was performed to assess the mRNA levels of Yap and its downstream target genes,connective tissue growth factor(Ctgf),and cysteine-rich protein 61(Cyr61).② EPSCs were exposed to 60 Co γ at a dose of 4 or 8 Gy,while the control group was not irradiated.Cells were collected to detect the levels of YAP protein via Western blotting.Cells were collected at 4,12,24,and 36 h post-IR to assess the levels of YAP mRNA by RT-qPCR.③ Short hairpin RNA(shRNA)was used to establish stable YAP knockdown cell lines,and the knockdown efficiency of sh YAP was verified by Western blotting.RT-qPCR was then performed to detect the impact of YAP knockdown on mRNA levels of K1 and K10 after IR.RESULTS① Compared with the control group,the YAP protein level in the IR group during wound healing was significantly reduced(P<0.05,P<0.01),so were the mRNA levels of Yap and its downstream target genes Ctgf and Cyr61(P<0.05,P<0.01).② Compared to the cell control group,the mRNA and protein levels of YAP in the IR group cells were significantly reduced(P<0.01).③ In the sh YAP cells,the YAP protein level was significantly reduced(P<0.01).Furthermore,the mRNA levels of K1 and K10 were significantly decreased after IR in sh YAP cells(P<0.01).CONCLUSION YAP can regulate EPSC differentiation in wound healing after IR.

Chronic atrophic gastritis (CAG), a common disease of digestive system, is an extremely important cause of gastric cancer (GC). The occurrence and development of CAG involves the abnormality of multiple signaling pathways. Traditional Chinese medicines (TCMs) has the advantages of mild action, multi-target and small adverse reaction, etc., which broadens the way for the treatment of the disease, and TCMs can play a therapeutic role by regulating multiple signaling pathways. In this review, based on the related experiments of TCMs and Chinese herbal compounds in recent years, the related literatures were searched and 10 kinds of signaling pathways involved were summarized, in order to provide a reference for further research on reversing or delaying the progress of CAG and preventing gastric cancer.

The ticks feed large amount of blood from their hosts and transmit pathogens to the victims. The salivary gland plays an important role in the blood feeding. When the female ticks are near engorgement, the salivary gland gradually loses its functions and begins to rapidly degenerate. In this study, data-independent acquisition quantitative proteomics was used to study changes in the phosphorylation modification of proteins during salivary gland degeneration in Haemaphysalis longicornis. In this quantitative study, 400 phosphorylated proteins and 850 phosphorylation modification sites were identified. Trough RNA interference experiments, we found that among the proteins with changes in phosphorylation, apoptosis-promoting Hippo protein played a role in salivary gland degeneration.
