Downregulation of alpha-fetoprotein siRNA inhibits proliferation of SMMC-7721 cells

AIM: To study the function of α-fetoprotein (AFP) in SMMC-7721 hepatoma cells.METHODS: A hairpin siRNA expressing plasmid pSilencer3.0-H1-afp was constructed and transfected into SMMC-7721 cells with Lipofectamine 2000. The expression of AFP was monitored by real-time RT-PCR and immunoassays, its effect on SMMC-7721 cell proliferation and cell death was detected by MTT and fluorescenceactivated cell sorter (FACS).RESULTS: The AFP-siRNA expressing plasmid downregulated the expression of AFP obviously (about 34%), and inhibited SMMC-7721 cell proliferation, but did not induce apoptosis.CONCLUSION: Downregulation of AFP siRNA inhibits proliferation of SMMC-7721 cells, but cannot cause apoptosis.

Research progress in the treatment of perimenopausal abnormal uterine bleeding with traditional Chinese and western medicine

In order to fully understand the research progress of Chinese and Western medicine in the treatment of perimenopausal abnormal uterine bleeding,this paper reviews all kinds of research by referring to related literature reports at home and abroad.The results showed that western medicine mainly used hormone drugs,supplemented by surgery,but the clinical adverse reactions were more and the recurrence rate was higher;traditional Chinese medicine often obtained satisfactory results through the treatment of traditional Chinese medicine,syndrome differentiation,stage treatment,acupuncture and other treatment methods,with fewer adverse reactions and low recurrence rate,but the effect of sudden collapse and hemostasis was slower;the combination of Chinese and Western medicine can learn from each other and become The research focus in recent years is worthy of further discussion.

Interactions of thymic stromal lymphopoietin with interleukin-4 in adaptive immunity during Aspergillus fumigatus keratitis

AIM:To investigate the potential interactions of thymic stromal lymphopoietin(TSLP)with interleukin-4(IL-4)in adaptive immunity during fungal keratitis(FK).METHODS:An FK mouse model was induced with Aspergillus fumigatus(AF)hyphal infection.Mice were divided into several groups:untreated,phosphate buffer saline(PBS),infected with AF,and pretreated with a scrambled siRNA,a TSLP-specific siRNA(TSLP siRNA),murine recombinant TSLP(rTSLP),immunoglobulin G(IgG),murine recombinant IFN(rIFN-γ),murine recombinant IL-4(rI L-4),rIL-13,murine recombinant IL-17A(rIL-17A),and murine recombinant IL-17F(rIL-17F)groups.Quantitative realtime reverse transcription-polymerase chain reaction(qRTPCR)and enzyme-linked immunosorbent assay(ELISA)or Western blot were performed to determine mRNA and protein levels in the inflamed cornea.Cytokine locations were observed by immunofluoresence staining after AF hyphal infection.RESULTS:Compared to those in the untreated group,TSLP and T helper type 1(Th1)cytokine levels in the AF group were upregulated at 24 h post infection(hpi),and those of T helper type 2(Th2)and T helper type 17(Th17)cytokines were increased at 5 d post infection(dpi).Th2 cytokine levels were decreased in the TSLP siRNA-pretreated group and increased in the rTSLP-pretreated group compared with the AF group.The TSLP level was increased in the rIL-4-pretreated group,but there were no significant changes among the other groups.Immunofluorescence staining showed cytokine locations after AF hyphal infection.CONCLUSION:TSLP induces a Th2 immune response and promots Th2 T cell differentiation in vivo.IL-4 promotes TSLP secretion.Therefore,TSLP with IL-4 regulates adaptive immunity in FK.

Professor Zhao Quan-lin's experience in the diagnosis and treatment of type 2 diabetes mellitus with acute gout

Type 2 diabetes mellitus(T2DM)is a common clinical endocrine and metabolic disease characterized by elevated blood sugar and insulin resistance.The onset of T2DM will affect the metabolic balance of the body,and uric acid metabolism is one of them.Hyperuricemia(HUA)is very common in type 2 diabetes.Based on HUA,gout is a crystal-related disease caused by urate deposition,and its clinical manifestations are complex and varied.Professor zhao quanlin has rich experience in clinical experience,and he has made good use of traditional Chinese medicine system to treat type 2 diabetes mellitus with gout in the acute phase of clinical effect.

Effects of marine omega-3 PUFA on adiponectin and leptin in overweight and obese patients: A meta-analysis of randomized controlled trials

Objective:To systematically evaluate the effect of marine Omega-3 polyunsaturated fatty acids(Omega-3 PUFA)on adiponectin and leptin levels in overweight and obese patients.Methods:The computer searched PubMed,Embase,Cochrane Library and CNKI electronic databases for randomized controlled experiments on the levels of marine Omega-3 PUFA and adiponectin and leptin in overweight and obese patients.The two researchers independently screened,evaluated and included the literatures and extracted the data.Meta analysis was carried out with Revman 5.3 software.Results:A total of 8 articles and 607 subjects were included.The results showed that Omega-3 PUFA from marine sources did not increase in adiponectin levels[SMD=0.32,95%CI=(-0.13,0.76)],while there was no significant did not reduce the leptin level of patients[SMD=-0.22,95%CI=(-0.53,0.09)].Conclusion:Marinederived Omega-3 PUFA can improve circulating leptin and adiponectin levels in overweight and obese patients,increase serum adiponectin levels and reduce leptin levels,but the difference is not obvious.Further research is still needed to determine the effect of Omega-3 PUFA on Adipokine in overweight and obese people.

Analysis of the relationship between liver-qi stagnation and premature ovarian failure based on exosomes

The incidence of premature ovarian failure,which is related to women’s excessive pressure and mental tension,has increased in recent years.Premature ovarian failure has become one of the diseases that seriously disturb women’s physical and mental health,and its incidence can be regarded as liver depression and qi stagnation.Patients have an increasing demand for treatment,not only for fertility with the improvement of social living standards and the development of healthcare technology.Exosomes,as small membrane vesicles containing complex RNA and proteins,have the function of mediating cell communication and transmitting information in the pathological state caused by liver-qi stagnation.Exosomes in the hypoxic microenvironment can protect cells from damage and promote the pathological process.Moreover,exosomes in an inflammatory environment can play an active anti-inflammatory role.Exosomes can reduce the apoptosis of granulosa cells by expressing miRNA and so on to restore ovarian function.The purpose of treating premature ovarian failure can be achieved in this way.This paper introduced the relationship between the three,discussed the guiding significance of Chinese medicine theories in the treatment of exosomes and premature ovarian failure,and provided new research ideas for the treatment of integrated traditional Chinese medicine and western medicine.

K63-linked polyubiquitination of IRF1： an essential step in the IL-1 signaling cascade

Interleukin 1 （IL-1） is a pleiotropic cytokine that regulates immune and inflammatory responses by inducing the expression of a variety of pro-inflamma- tory cytokines and chemokines. IL-1 exerts its pro-inflammatory effects primarily by activating nuclear factor KB （NF-rB） and mitogen-activated protein kinases （MAPKs）. After binding to its receptor
