Osteoporosis （OP） is a systemic metabolic bone disease characterized by bone microstructure degeneration and bone mass loss， which has a high prevalence and disability rate. Effective prevention and treatment of OP is a major difficulty in the medical community. The nature of OP is that multiple pathological factors lead to the imbalance of human bone homeostasis maintained by osteoblasts and osteoclasts. Ferroptosis is a non-apoptotic cell death pathway， and its fundamental cause is cell damage caused by iron accumulation and lipid peroxidation. Studies have shown that ferroptosis is involved in and affects the occurrence and development of OP， which leads to OP by mediating the imbalance of bone homeostasis. Ferroptosis is an adjustable form of programmed cell death. The intervention of ferroptosis can regulate the damage degree and death process of osteoblasts and osteoclasts， which is beneficial to maintain bone homeostasis， slow down the development process of OP， improve the clinical symptoms of patients， reduce the risk of disability， and improve their quality of life. However， there are few studies on ferroptosis in OP. Traditional Chinese medicine （TCM） is a medical treasure with unique characteristics and great application value in China. It has been widely used in China and has a long history. It has the multi-target and multi-pathway advantages in the treatment of OP， with high safety， few toxic and side effects， and low treatment cost， and has a significant effect in clinical application. The intervention of TCM in ferroptosis to regulate bone homeostasis may be a new direction for the prevention and treatment of OP in the future. This article summarized the regulatory mechanisms related to ferroptosis， discussed the role of ferroptosis in bone homeostasis， and reviewed the current status and progress of active ingredients in TCM compounds and monomers in the regulation of OP through ferroptosis， so as to provide a theoretical basis for the participation of TCM in the prevention and treatment of OP in the future.

ObjectiveTo clarify the therapeutic effect of Huashi Baidu prescription on pneumonia in mice caused by influenza A （H1N1） virus and explore its mechanism based on the transcriptome. MethodA mouse influenza viral pneumonia model was built by intranasal infection with influenza A virus， and mice were continuously administered the drug for five days， so as to investigate the general condition， lung index， viral load， pathological morphology of lung tissue， survival time， and prolongation rate of survival time of mice and clarify the therapeutic effect of Huashi Baidu prescription on influenza viral pneumonia. Transcriptome technology was used to detect the differentially expressed genes in the lung tissue of mice in the model group and the normal group， as well as the Huashi Baidu prescription group and the model group， and the potential core target of the Huashi Baidu prescription for the treatment of influenza viral pneumonia was screened. Real-time fluorescence quantitative polymerase chain reaction （Real-time PCR） was used to verify the effect of Huashi Baidu prescription on the mRNA expression level of core target genes. ResultCompared with the normal group， the lung index and viral load in the lung tissue of the model group were significantly increased （P<0.05， P<0.01）. Compared with the model group， the high-dose group of Huashi Baidu prescription significantly prolonged the survival time of mice infected with influenza A virus （P<0.05） and significantly reduced the lung index value of mice （P<0.05） and the viral load of lung tissue. The high-dose， medium-dose， and low-dose groups of Huashi Baidu prescription could significantly reduce lung tissue inflammation， blood stasis， swelling， and other pathological changes in mice （P<0.05， P<0.01）. Transcriptome analysis of lung tissue showed that core genes were mainly enriched in the nuclear transcription factor-κB （NF-κB） signaling pathway， interleukin-17 （IL-17） signaling pathway， cytokine-cytokine receptor interaction， and other pathways after the intervention of Huashi Baidu prescription. TRAF6， NFKBIA， CCL2， CCL7， and CXCL2 were the top five node genes with combined score values. Real-time PCR validation showed that Huashi Baidu prescription significantly downregulated the mRNA expression of key genes TRAF6 and NFKBIA in the NF-κB signaling pathway， as well as chemokines CCL2， CCL7， and CXCL2 （P<0.05， P<0.01）. ConclusionHuashi Baidu prescription has a therapeutic effect on influenza viral pneumonia， possibly by inhibiting the expression of key nodes TRAF6 and NFKBIA in the NF-κB signaling pathway and that of chemokines CCL2， CCL7， and CXCL2， reducing the recruitment of inflammatory cells and viral load， and exerting anti-influenza viral pneumonia effects.

Objective:To preliminarily observe the clinical efficacy of microwave hyperthermia combined with intensity-modulated radiotherapy (IMRT) and chemotherapy for patients with locally advanced gastric cancer.Methods:Forty patients who could not been operated or refused operation were enrolled in this clinical trial, who were confirmed as locally advanced proximal or distal gastric cancer by gastroscopy pathology and imaging. Radiotherapy was delivered by IMRT technology for 5 times per week with a total dose of 46 to 56 Gy (median dose of 50 Gy) in 25 to 28 fractions. Synchronous hyperthermia was given at 42 to 44℃ twice a week, 45 min/time. S-1 or capecitabine-based synchronous chemotherapy was performed, d1-14/3 weeks. The symptom remission rate, adverse reactions, objective remission rate (complete and partial remission) and survival were observed.Results:A total of 40 patients, aged between 56 and 83 years (median age of 71 years), were enrolled in this study. The male-to-female ratio was 7: 1. Among them, 38 cases (95%) showed symptom remission. The most common adverse reactions were grade 1-2 gastrointestinal reactions and leukopenia. The objective remission rate was 87.5%, the 2-year progression-free survival and overall survival rates were 68.6% and 70.5%, respectively.Conclusion:Preliminary findings demonstrate that microwave hyperthermia combined with chemoradiotherapy achieve satisfactory outcomes and yield tolerable toxicity in patients with locally advanced gastric cancer.

Objective:To analyze the clinical manifestations and laboratory features in patients with myeloid neoplasms complicated with clonal T large granular lymphocyte (T-LGL) proliferation.Methods:The clinical data of 5 patients with myeloid neoplasms complicated with clonal T-LGL proliferation from November 2017 to November 2018 in Institute of Hematology & Blood Diseases Hospital, Chinese Academy of Medical Sciences & Peking Union Medical College were analyzed retrospectively.Results:The median age was 60 years old. All patients had a history of abnormal peripheral blood cell counts for over 6 months. The absolute lymphocyte count in peripheral blood was less than 1.0×10 9/L. In addition to the typical T-LGL phenotype, the immunophenotype was heterogenous including CD4 +CD8 - in 2 patients, the other 3 CD4 -CD8 +. Four patients were αβ type T cells, the other one was γδ type. STAT3 mutation was detected in 1 patient by next-generation sequencing, the other 4 cases were negative. Conclusions:Clonal T-LGL proliferation with myeloid neoplasm develops in an indolent manner, mainly in elderly patients. Hemocytopenia is the most common manifestation. The diagnosis of T-LGL proliferation does not have specific criteria, that it should be differentiated from other T cell proliferative disorders, such as T-cell clones of undetermined significance. STAT3 or STAT5b mutation may help distinguish.

Objective To explore the effect of invasion and migration of hepatocellular carcinoma (HCC) endothelial cells (TECs) affected by overexpression of microRNA-3178 (miR-3178) through the transfection of miR-3178 mimic.Methods Real-time polymerase chain reaction (Real-time PCR) was used to identify differential expression of miR-3178 in normal hepatic sinusoidal endothelial cells (HSECs) and HCC TECs.Furthermore,HCC TECs were divided into 3 groups:control (CON) group,miRNA-3178 upregulation (Mimics,up-regulation of miR-3178 expression was achieved using miR-3178 mimics transfected into HCC TECs) group and negative control (NC,negative control sequence was transfected into HCC TECs) group.RT-PCR was used to detect expression of miR-3178 in HCC TECs before and after transfection.Transfection efficiency was observed by using an inverted fluorescence microscope.HCC TECs invasionand migration were measured by matrigel invasion and transwell migration assay.EGR3 protein expression of HCC TECs were identified by Western blotting analysis.EGR3 mRNA expression of HCC TECs were identified by RT-PCR analysis.Results The results of RT-PCR showed that miR-3178 was significantly down-regulated in HCC TECs compared to HSECs (P ＜0.05),and expression of miR-3178 was significantly increased after the transcienttransfection (P ＜ 0.05).The transfection efficiency in HCC TECs was morethan 90％.Number of migrated and invaded cells and in miR-3178 group was significantly less than those in other groups.Target gene prediction software showed EGR3 was a possible candidate target.Transfection of miR-3178 mimic significantly decreased the mRNA and protein expression levels of EGR3.Conclusion MiR-3178 was downregulated in HCC TECs and overexpression of miR-3178 can specifically inhibit migration and invasion of HCC TECsin vitro through inhibiting EGR3 expression,thus,miR-3178 might be a critical targeted therapy strategv for HCC.

BACKGROUND:Recently, the effects of human umbilical cord mesenchymal stem cel s (hUCMSCs) and placenta-derived mesenchymal stem cel s (PDMSCs) on treatment of acute graft versus host disease (aGVHD) have been confirmed in some in vitro studies or animal models. But there are stil no reports comparing the therapeutic effects of these two cel types. OBJECTIVE:To compare the immunosuppressive function of hUCMSCs and PDMSCs in vitro or in a mouse aGVHD model. METHODS:(1) In vitro experiment. Human peripheral blood mononuclear cel s (PBMCs) were isolated and divided into four groups:PBMCs cultured alone, PBMCs stimulated with phytohaemagglutinin (PHA), PHA stimulated-PBMCs cocultured with hUCMSCs, PHA stimulated-PBMCs cocultured with PDMSCs. After 5 days, PBMCs proliferation and interferon-γlevel in cel supernatant were measured. (2) In vivo experiment. Fifty-seven BABL/C(H-2d) mice exposed to 8.5 Gy irradiation were randomly divided into five groups:only saline injection group, syngeneic bone marrow transplantation group, al ogeneic bone marrow transplantation group, aGVHD group, hUCMSCs treatment group, PDMSCs treatment group. The clinical aGVHD score, histopathology of skin, liver, and smal intestine, and survival time were analyzed at days 11, 14, 21 after transplantation. RESULTS AND CONCLUSION:(1) In vitro test:compared with the hUCMSCs, PDMSCs had stronger anti-inflammatory function. (2) In vivo test:The clinical scores on acute graft versus host disease were significantly lower in the hUCMSCs and PDMSCs treatment groups than that in the aGVHD group (P<0.05). The survival rates of mice were significantly increased in the hUCMSCs and PDMSCs treatment groups compared to the aGVHD group (P<0.05). Evident skin lesions were not found in al groups. Although smal intestine mucosal lesions were found in al groups, the damage level seemed similar. Notably, significant difference was found in the liver that multifocal necrosis and a large number of inflammatory cel s were seen in the aGVHD group, but less necrosis and inflammatory cel s in the hUCMSC and PDMSC treatment groups. In conclusion, hUCMSC and PDMSC are comparably effective in the treatment of aGVHD in mice.

UNLABELLEDObjective To explore the effects of sperm DNA integrity rate, acrosome integrity rate and acrosome reaction rate on the outcomes of rescue intracytoplasmic sperm injection (ICSI).

METHODSThis retrospective analysis was conducted among 97 infertile couples receiving rescue ICSI due to failure of in vitro fertilization procedures in our Reproductive Medicine Center. Of these 97 women, 41 had clinical pregnancy and 56 did not, and the effects of sperm DNA integrity rate (estimated by DNA fragmentation index, DFI), acrosome integrity rate and acrosome reaction rate on rescue ICSI outcomes were analyzed.

RESULTSNo significant difference was found in paternal age, testosterone value, testicular volume, FSH, female patient' age or the number of eggs retrieved between the two groups (P>0.05), but the infertility years was significantly shorter in the pregnancy group than in the non-pregnancy group (P<0.05). The fertilization rate and cleavage rate were similar between the two groups (P>0.05), but the good embryo rate was significantly higher in the pregnancy group (P<0.05). The sperm DNA integrity or acrosome reaction rate did not differ significantly between the two groups (P>0.05), but the acrosome integrity rate was significantly higher in the pregnancy group (P<0.05). The sperm DNA integrity rate, acrosome integrity or acrosome reaction rate were not correlated with the fertilization rate, cleavage rate or good embryo rate (P>0.05). The pregnancy rate, twin and single fetus rates were 42.3%, 10.3% and 32.0% in this cohort after recue ICSI, respectively.

CONCLUSIONRescue ICSI is an effective treatment after failed in vitro fertilization procedure, and sperm acrosome integrity rate is associated with the outcome of rescue ICSI.
