ObjectiveTo investigate the effects of Linggui Zhugantang on mitochondrial fission and fusion and silencing information regulator 3(Sirt3)/adenosine monophosphate dependent protein kinase (AMPK) signaling pathway in chronic heart failure (CHF) rats after myocardial infarction (MI). MethodSD rats randomly divide into sham operation group (normal saline ,thread only without ligature), model group (normal saline, ligation of the left anterior descending coronary artery proximal to the heart), Linggui Zhugantang group (4.8 g·kg-1) and Captopril group (0.002 57 g·kg-1), with 10 rats in each group. Administere drug continuously for 28 days. Echocardiography detected cardiac function parameters. Hematoxylin eosin (HE) staining observed the pathological changes of the heart. Immunofluorescence detected the levels of reactive oxygen species (ROS). JC-1 detect mitochondrial membrane potential. Colorimetry measure adenosine triphosphate (ATP), superoxide dismutase (SOD), malondialdehyde (MDA), mitochondrial respiratory chain complex activity (Ⅰ-Ⅳ). TdT-mediated dUTP nick end labeling (TUNEL) staining detected the apoptosis rate of myocardial tissue. Western blot detected protein expression levels of Sirt3, phosphorylated AMPK (p-AMPK), phosphorylated dynamic-related protein 1(p-Drp1), mitochondrial fission protein 1(Fis1), mitochondrial fission factor (MFF), optic atrophy protein 1(OPA1). ResultCompared to the sham group, the left ventricular end diastolic diameter (LVIDd) and left ventricular end systolic diameter (LVIDs) were significantly increased in model group (P<0.01), while the left ventricular short axis shortening rate (LVFS) and left ventricular ejection fraction (LVEF) were significantly decreased (P<0.01). There were inflammatory cell infiltration and obvious pathological injury in myocardial tissue. ROS, MDA levels and myocardial cell apoptosis rate were significantly increased (P<0.01), SOD level, ATP content, and membrane potential were significantly decreased (P<0.01). The activity of mitochondrial respiratory chain complexes (Ⅰ-Ⅳ) was significantly decreased (P<0.01). Levels of p-Drp1, Fis1, MFF proteins were significantly up-regulated (P<0.01), while Sirt3, p-AMPK, OPA1 proteins level were significantly down-regulated (P<0.01). Compared with model group, LVIDd and LVIDs were significantly decreased (P<0.01), LVEF and LVFS were significantly increased (P<0.01). Inflammatory cell infiltration and pathological damage of myocardial tissue were significantly relieved. ROS, MDA levels and myocardial cell apoptosis rate were significantly decreased in Linggui Zhugantang group and Captopril group (P<0.01), SOD level, ATP content, and membrane potential significantly increased (P<0.01). The activity of mitochondrial respiratory chain complexes (Ⅰ-Ⅳ) increased significantly (P<0.01),and p-Drp1, Fis1, MFF protein levels were significantly down-regulated (P<0.01), Sirt3, p-AMPK, OPA1 protein were significantly up-regulated (P<0.01). ConclusionLinggui Zhugantang can alleviate oxidative stress and apoptosis damage of myocardial cells, maintain mitochondrial function stability, and its effect may be related to mitochondrial mitosis fusion and Sirt3/AMPK signaling pathway.

Aim To clarify the differential proteins of mammary tissues in Xihuang pills(XHP)against hy-perplasia of mammary glands(HMG)based on quanti-tative proteomics technology and validate them,and to explore the mechanism of action.Methods SD rats were randomly divided into blank group,model group and XHP group,with 10 rats in each group.Except for the blank group,estrogen and progesterone were injec-ted intramuscularly to establish a rat model of mamma-ry hyperplasia for 30 d.After XHP was administered for 14 d,the rats in each group were observed to have morphological changes in the apparent morphology of the mammary tissues,and pathological changes in the mammary tissues were stained with hematoxylin-eosin staining(HE),and the differentially expressed pro-teins(DEPs)in the groups were screened by quantita-tive proteomics technology and subjected to bioinforma-tics analysis,and Western blot to verify the key DEPs.Results Compared with the model group,the appar-ent pathological morphology of the XHP group was sig-nificantly improved,the diameter of the nipple height of the rats was significantly reduced(P<0.01),and the degree of histopathology was significantly allevia-ted.Quantitative proteomics identified 4,299 DEPs in mammary tissue,and bioinformatics analysis of 14 DEPs with consistent changes between the XHP group and the blank group relative to the model group re-vealed that they were related to the regulation of mus-cular systemic processes,regulation of muscle contrac-tion,DNA replication,and pre-initiation of DNA repli-cation.Western blot results showed that,compared with the model group,rat mammary tissue of the XHP group showed significantly lower levels of ACLY and ALDOC protein expression levels were significantly re-duced and BIN1 protein expression levels were signifi-cantly increased(P<0.01).Conclusions XHP may exert its anti-mammary hyperplasia effect through the regulation of BIN1,ACLY and ALDOC protein lev-els,the regulation of DNA replication,the regulation of pre-initiation of DNA replication and muscular sys-temic processes,and the regulation of muscle contrac-tion.

Objective: To investigate the genetic and genomic profiling of juvenile myelomonocytic leukemia (JMML) and factors affecting its survival rate. Methods: Clinical characteristics, cytogenetics, molecular biology results and survival status of children with 27 JMML cases admitted to the Hematology Department of Children's Hospital, Capital Institute of Pediatrics from December 2012 to December 2021 were analyzed retrospectively, and the outcomes of the children were followed up. Kaplan-Meier method was used for survival analysis. Univariate analysis was used for analyzing factors affecting the overall survival (OS) rates of patients who received hematopoietic stem cell transplantation (HSCT). Log-Rank test was used for comparison of survival curves. Results: Among 27 JMML cases, there were 11 males and 16 females. The age of disease onset was 28 (11,52) months. There are 20 cases of normal karyotype, 4 cases of monosomy 7, 1 case of trisomy 8,1 case of 11q23 rearrangement and 1 case of complex karyotype. A total of 39 somatic mutations were detected.Those involved in RAS signal pathway were the highest (64%(25/39)), among which PTPN11 mutation was the most frequent (44% (11/25)). A total of 17 cases (63%) received HSCT, 8 cases (30%) did not receive HSCT, and 2 cases (7%) lost follow-up. For children receiving transplantation, the follow-up time after transplantation was 47 (11,57) months. The 1-year OS rate of high-risk transplantation group (17 cases) and high-risk non transplantation group (6 cases) was (88±8)% and (50±20)% respectively, with a statistically significant difference (χ2=5.01, P=0.025). The 5-year OS rate of the high-risk transplantation group was (75±11)%. The survival time of those who relapsed or progressed to acute myeloid leukemia after transplantation was significantly shorter than that of those who did not relapse (χ2=6.80, P=0.009). The OS rate of patients with or without PTPN11 mutation was (81±12) % and (67±19)% respectively (χ2=0.85, P=0.356). Conclusions: The main pathogenesis involved in JMML is gene mutation related to RAS signaling pathway, and the most common driver gene of mutation is PTPN11. Allogeneic HSCT can significantly improve the survival rate of high-risk JMML patients. The recurrence or progression after transplantation was related to poor prognosis.

Sintilimab is an anti-programmed cell death receptor-1 antibody. The phase III clinical trial ORIENT-12 confirmed the safety of sintilimab combined with pemetrexed/platinum in the treatment of advanced squamous non-small cell lung cancer. Skin reactions are the most commonly reported adverse events of immune checkpoint inhibitors and are rarely severe.We describe a case of toxic epidermal necrolysis related to sintilimab in an elderly oncologic patient. 3 weeks after immunotherapy, the patient developed an extensive rash and diffuse itching, rapidly evolving into macules, blisters, bullae and erosions. Causal evaluation was performed based on the algorithm of drug causality for epidermal necrolysis and national Food and Drug Administration qualitative analysis. The patient responded to high-dose glucocorticosteroid and supportive therapy, alongside with local wound care. If immune checkpoint inhibitors need to be extrapolated clinically, strictly following evidence-based research, promptly detecting and treating adverse reactions is crucial.

To date, there is little information about the demography of vasectomy reversal (VR) patients or the factors currently influencing VR effectiveness in China, especially after the universal two-child policy was released in 2015. In this research, demographic data and perioperative medical records of VR patients were extracted from seven major hospitals in different provinces or municipalities of China. Meanwhile, a telephone survey of the patients was conducted to collect follow-up information. Eventually, 448 VR cases from the past 13 years were included. The results were analyzed by stratified comparison to investigate factors that can influence postoperative vas deferens patency and pregnancy rate. Appropriately statistical methods were used, and all of the protocols were approved by the Ethics Committees of the institutes in this research. The results showed that the annual operation volume of VR quadrupled after the two-child policy was implemented. Nonmicrosurgery and a long duration of vasectomy were significantly associated with a lower patency rate. A follow-up survey showed that the general postoperative pregnancy rate was 27.2%. For female partners over the age of 35 years, the postoperative pregnancy rate showed a more severe decline, but only 35.5% of them had been given a fertility examination before their husbands' VR surgery. Our work revealed that more patients in China have been demanding VR in recent years. High-quality microsurgery and a short duration of vasectomy are crucial for restoring patency by VR. Clinical andrologists should perform a preoperative fertility evaluation of the patients' female partners.

OBJECTIVE:
Depression and metabolic disorders have overlapping psychosocial and pathophysiological causes. Current research is focused on the possible role of adiponectin in regulating common biological mechanisms. Xiaoyao San (XYS), a classic Chinese medicine compound, has been widely used in the treatment of depression and can alleviate metabolic disorders such as lipid or glucose metabolism disorders. However, the ability of XYS to ameliorate depression-like behavior as well as metabolic dysfunction in mice and the underlying mechanisms are unclear.
METHODS:
An in vivo animal model of depression was established by chronic social defeat stress (CSDS). XYS and fluoxetine were administered by gavage to the drug intervention group. Depression-like behaviors were analyzed by the social interaction test, open field test, forced swim test, and elevated plus maze test. Glucose levels were measured using the oral glucose tolerance test. The involvement of certain molecules was validated by immunofluorescence, histopathology, and Western blotting. In vitro, hypothalamic primary neurons were exposed to high glucose to induce neuronal damage, and the neuroprotective effect of XYS was evaluated by cell counting kit-8 assay. Immunofluorescence and Western blotting were used to evaluate the influences of XYS on adiponectin receptor 1 (AdipoR1), adenosine 5'-monophosphate-activated protein kinase (AMPK), acetyl-coenzyme A carboxylase (ACC) and other related proteins.
RESULTS:
XYS ameliorated CSDS-induced depression-like behaviors and glucose tolerance impairment in mice and increased the level of serum adiponectin. XYS also restored Nissl bodies in hypothalamic neurons in mice that exhibited depression-like behaviors and decreased the degree of neuronal morphological damage. In vivo and in vitro studies indicated that XYS increased the expression of AdipoR1 in hypothalamic neurons.
CONCLUSION
Adiponectin may be a key regulator linking depression and metabolic disorders; regulation of the hypothalamic AdipoR1/AMPK/ACC pathway plays an important role in treatment of depression by XYS.

ObjectiveTo observe the effect of Xianlian Jiedu prescription (XLJDP) on the proliferation, apoptosis, and migration of cancer-relative endothelial (CRE) cells, and to decipher the mechanism of XLJDP in regulating angiopoietin2 (Ang2) to maintain CRE cell homeostasis and inhibit tumor neovascularization. MethodHuman umbilical vein endothelial cell line (HUVEC-c) was induced into CRE cells in the human colorectal cancer HCT-116 cell-conditioned medium. The CRE cells were assigned into the blank group, conditioned medium group, and XLJDP groups (1, 2, 3 g·L-1) and treated for 48 h. The proliferation of CRE cells was detected by methyl thiazolyl tetrazolium (MTT) colorimetry. The morphological changes of CRE cells were observed via an inverted microscope. The apoptosis rate was detected by flow cytometry. Wound healing test and Transwell migration assay were employed to detect the 2D/3D migration ability of CRE cells. The protein levels of vimentin, N-cadherin, matrix metalloproteinase-9 (MMP-9), and Ang2 in CRE cells were measured by Western blot. ResultThe MTT results showed that the cell viability was higher in the conditioned medium group than in the blank group (P<0.05). Compared with the conditioned medium group, XLJDP decreased the cell proliferation rate (P<0.01) and changed the cell morphology. The total apoptosis rates of all the XLJDP groups were higher than that of the conditioned medium group (P<0.01). The 2D and 3D migration abilities of the conditioned medium group were higher than those of the blank group (P<0.05, P<0.01). Compared with the conditioned medium group, XLJDP at all the concentrations weakened the 2D migration ability (P<0.01) and medium- and high-concentration XLJDP weakened the 3D migration ability (P<0.01). The protein levels of N-cadherin, Vimentin, MMP-9, and Ang2 were up-regulated in the conditioned medium group compared with those in the blank group (P<0.05, P<0.01). Compared with the conditioned medium group, XLJDP at all the concentrations down-regulated the protein level of Ang2 (P<0.05, P<0.01), and medium- and high-concentration XLJDP down-regulated those of N-cadherin, vimentin, and MMP-9 protein (P<0.01). ConclusionXLJDP may inhibit the proliferation, migration, differentiation, and apoptosis of CRE cells by down-regulating the expression of Ang2, inhibiting tumor neovascularization, and maintaining the cell homeostasis.
