OBJECTIVE To explore the mechanism of Shenqi guben formula （SQGB） in improving cancer-related fatigue （CRF） based on network pharmacology and cellular experiments. METHODS Active components of SQGB and CRF-related targets were identified on the basis of databases such as the Traditional Chinese Medicine Systems Pharmacology platform. An in vitro CRF cell model was established by inducing A549 cells with interleukin-17 （IL-17）. Cells were treated with low （1.0 mg/mL） or high （1.5 mg/mL） concentrations of SQGB. The effects on cell viability， migration， apoptosis， inflammatory factors， mRNA expression， apoptosis-related proteins and key proteins 011） of IL-17 signaling pathway were evaluated using scratch assay， flow cytometry， ELISA， real-time fluorescent quantitative PCR and Western blot analysis. RESULTS SQGB contained 84 active components acting on 209 potential CRF targets. Among E-these， quercetin， kaempferol， and luteolin were identified as the core components of the compound. Core targets included tumor protein p53， AKT serine/threonine kinase 1， IL-6， and tumor necrosis factor （TNF）. IL-17， TNF and phosphatidylinositol-3- kinase-serine/threonine protein kinase （PI3K/Akt） signaling pathways were identified as crucial pathways. Compared with IL-17 intervention group， the cell migration rate， B-cell lymphoma 2 （Bcl-2） protein expression， the levels of IL-6 and TNF-α in the supernatant， mRNA expression of IL-17 receptor A （IL-17RA）， TNF-α， and IL-6， as well as the protein expression of IL-17RA and nuclear factor kappa-B p65 subunit （p65）， and phosphorylated （p）-p65/p65 ratio in IL-17+SQGB low- and high- quality concentration groups were all significantly decreased or down-regulation （P＜0.05）； the apoptosis rate， expression levels of Bcl-2 associated X protein （Bax） and cleaved caspase-3 protein， the ratio of Bax/Bcl-2， the expression level of p-p38 protein， and the p- p38/p38 ratio were all significantly increased or up-regulated （P＜0.05）. Moreover， the improvement effects of these indicators were mostly better in the high-quality concentration groups compared to the low-quality concentration groups （P＜0.05）. CONCLUSIONS SQGB ameliorates CRF by regulating the IL-17 signaling pathway， inhibiting the expression of inflammatory factors， and activating p38 MAPK-dependent apoptosis pathway.

Sepsis is one of the common severe diseases caused by the dysregulated host response to infection， which seriously threatens the life and health of human beings all over the world. The incidence and mortality of the disease are extremely high， and it has always been an urgent problem to be solved in the field of acute and critical diseases. At present， anti-infection， fluid resuscitation， mechanical ventilation and other programs are most used in clinic to treat sepsis， but their poor prognosis and high cost and other issues remain to be resolved. Therefore， it is necessary to explore a new， efficient， safe and inexpensive drug and treatment model at this stage. The treatment of traditional Chinese medicine （TCM） is based on syndrome differentiation and holistic concept. It can effectively regulate the progression of sepsis， maintain the homeostasis of the body， and has fewer adverse reactions. It has achieved good clinical results. In recent years， a large number of studies have shown that TCM can reduce the inflammatory response by regulating the Toll-like receptor 4（TLR4） signaling pathway， thereby reducing the severity and mortality of sepsis patients. However， there is still a lack of systematic exposition of TCM regulating TLR4 signaling pathway in the treatment of sepsis. Therefore， this article summarizes the relationship between TLR4 signaling pathway and sepsis and the mechanism of TCM in the disease by searching and consulting relevant literature in recent years. It is found that some Chinese medicine monomers and active ingredients， Chinese medicine compounds and Chinese medicine preparations can effectively reduce systemic inflammatory response， repair organ damage and improve the prognosis of sepsis by inhibiting the activation of TLR4 signaling pathway. However， due to various limitations， some studies have directly focused on the differential expression and function of TLR4， ignoring the downstream molecular expression and phenotypic effects of TLR4. The alternative mechanism， relationship and specific molecular mechanism of the pathway are still unclear. There are problems such as unclear pharmacokinetics and unclear mechanism in the pro- and anti-inflammatory balance， which need to be further studied and explored in order to provide new ideas for the potential treatment and drug development for sepsis.

BACKGROUND:Inherited heart disease has a high prevalence and mortality rate,but its pathogenesis has not yet been clarified.Although relevant animal models have been established to provide a foundation for the pathogenesis research of inherited heart disease,the value of these research results has been significantly reduced due to differences among species.Therefore,a new model is needed to explore its occurrence and development. OBJECTIVE:To review the current role of induced pluripotent stem cells in disease modeling and potential application prospects in various inherited heart diseases. METHODS:The first author searched the relevant articles published nearly 13 years in PubMed from January to March 2023.The search terms were"induced pluripotent stem cell,inherited heart disease,congenital heart disease".Finally,76 articles were included for analysis. RESULTS AND CONCLUSION:Since 2007,when induced pluripotent stem cells were induced from human somatic cells,many studies have been reported on disease-specific induced pluripotent stem cells.Due to the ability of disease-specific induced pluripotent stem cells to reproduce disease phenotypes,they are expected to become a new research tool for in vitro disease modeling,used to analyze pathogenesis and develop auxiliary drugs.In the research of cardiovascular genetic diseases,cardiomyocytes derived from patient-specific induced pluripotent stem cells contain gene mutations that are involved in cardiac dysplasia.Therefore,it can be used as a new tool to study the potential mechanisms of inherited heart disease.Up to now,induced pluripotent stem cells-derived cardiomyocytes have been widely used to study the molecular mechanisms of various genetic heart diseases,such as cardiac electrophysiological diseases,cardiomyopathy,and some syndromic inherited heart diseases.

Sepsis is a life-threatening Organ Dysfunction disease caused by the dysregulated response of the body to infection.It is characterized by fever,chills,shortness of breath,altered consciousness,and even severe complications such as Multiple Organ Dysfunction Syndrome(MODS).The morbidity and mortality of this disease are high year after year,and there are problems such as large consumption of medical resources and poor prognosis,which seriously affect the quality of life and economic burden of patients.Therefore,it is important to explore new treatments with high efficiency,safety and low cost.The disease pathogenesis is complex,including inflammation imbalance is the main pathogenesis of sepsis.Mitogen-Activated Protein Kinases(MAPK)signaling pathway is a signaling pathway activated by environmental factors or inflammatory factors,which mediates proliferation,differentiation,inflammatory response and apoptosis,and plays a key role in the occurrence and development of sepsis.At present,antibiotics,fluid resuscitation and mechanical ventilation are the main methods for clinical treatment of sepsis.Although they can curb the progress of some diseases,some treatment effects are not good.A large amount of literature has confirmed that Chinese medicine intervention in sepsis has significant advantages,its through many channels,regulation and control of multiple targets,MAPK signaling pathways,inhibit inflammation,strengthening immune defense and effective in the treatment of sepsis,sepsis is current research hotspot.However,there is still a lack of systematic reviews on the regulation of MAPK signaling pathway by traditional Chinese medicine in the treatment of sepsis.Therefore,based on the retrieval database sepsis related literature at home and abroad in recent years,a systemic summary of MAPK signal pathway and sepsis relations and the role of traditional Chinese medicine in them,will be new drugs for the treatment of sepsis and development provides new theoretical support.

Objective:To analyze the clinical phenotype, sperm morphological characteristics and assisted reproductive therapy efficiency in patients with total globozoospermia.Methods:Four male patients with total globozoospermia were collected during November 2019 to May 2022 from Reproductive Medical and Genetic Center, the People's Hospital of Guangxi Zhuang Autonomous Region. Peripheral blood samples were collected for genetic detection and the whole exome sequencing to explore the pathogenic genes. Semen characteristics, sperm morphology and ultrastructure were analyzed. Four patients were treated with intracytoplasmic sperm injection (ICSI) combined with artificial oocyte activation (AOA). Conventional ICSI cycles ( n=9) were selected as control group, and the development dynamic parameters were monitored by Time-lapse. The fertilization and embryo development parameters, developmental dynamic parameters and clinical outcomes were analyzed between the two groups. Results:Four patients were complicated with low sperm motility and increased sperm DNA fragmentation. Sperm morphology analysis and acrosome fluorescence staining represented that all the spermatozoas were with a small round head lacked of acrosome. By the transmission electron microscope, it was observed that round-headed spermatozoas were lacked of acrosome completely, loose chromatin structure, vacuolation and other abnormal changes in the head, mitochondrial sheath in neck were reduced arranged in disorder, and the structure of "9+2" of the flagellar axial filament was incomplete. Of the 4 patients, 1 was homozygous deletion of DPY19L2 gene and 1 was homozygous frameshift mutation of DPY19L2 gene. There were no significance differences in fertilization rate, two pronuclei fertilization rate, day 3 high-quality embryo rate, day 6 blastocyst formation rate and day 6 high-quality blastocyst formation rate between total globozoospermia group and control group (all P>0.05). The developmental dynamic parameters as the time at which the second polar body is extruded, the time when both (or the last) PN disappear, two to six discrete cells in the total globozoospermia group were significantly earlier than those in control group, and the difference was statistically significant (all P<0.05). There was no significant difference in the embryo cleavage patterns between the two groups ( P>0.05). Among the 4 patients with total globozoospermia, 2 live births with signal healthy male baby were achieved by fresh embryo transfer, and 2 live births with one signal healthy male baby and one healthy female baby were achieved by frozen-thawed embryo transfer respectively. Conclusion:Abnormal morphology characteristics of spermatozoas from patients with total globozoospermia are obvious, patients with total globozoospermia could have favorable clinical outcomes following ICSI combined with AOA.
