ObjectiveTo investigate the effect of transplantation of bone marrow mesenchymal stem cells （BMSCs） co-cultured with bone marrow-derived M2 macrophages （M2-BMDMs）， named as BMSCM2， on a rat model of liver cirrhosis induced by carbon tetrachloride （CCl4）/2-acetaminofluorene （2-AAF）. MethodsRat BMDMs were isolated and polarized into M2 phenotype， and rat BMSCs were isolated and co-cultured with M2-BMDMs at the third generation to obtain BMSCM2. The rats were given subcutaneous injection of CCl4 for 6 weeks to establish a model of liver cirrhosis， and then they were randomly divided into model group （M group）， BMSC group， and BMSCM2 group， with 6 rats in each group. A normal group （N group） with 6 rats was also established. Since week 7， the model rats were given 2-AAF by gavage in addition to the subcutaneous injection of CCl4. Samples were collected at the end of week 10 to observe liver function， liver histopathology， and hydroxyproline （Hyp） content in liver tissue， as well as changes in the markers for hepatic stellate cells， hepatic progenitor cells， cholangiocytes， and hepatocytes. A one-way analysis of variance was used for comparison of continuous data between multiple groups， and the least significant difference t-test was used for further comparison between two groups. ResultsCompared with the N group， the M group had significant increases in the activities of serum alanine aminotransferase （ALT） and aspartate aminotransferase （AST） （P<0.01）； compared with the M group， the BMSC and BMSCM2 groups had significant reductions in ALT and AST （P<0.01）， and the BMSCM2 group had significantly better activities than the BMSC group （P<0.05）. Compared with the N group， the M group had significant increases in Hyp content and the mRNA and protein expression levels of alpha-smooth muscle actin （α-SMA） in the liver （P<0.01）； compared with the M group， the BMSC and BMSCM2 groups had significant reductions in Hyp content and the expression of α-SMA （P<0.05）， and the BMSCM2 group had a significantly lower level of α-SMA than the BMSC group （P<0.01）. Compared with the N group， the M group had significant increases in the mRNA expression levels of the hepatic progenitor cell markers EpCam and Sox9 and the cholangiocyte markers CK7 and CK19 （P<0.01） and significant reductions in the expression levels of the hepatocyte markers HNF-4α and Alb （P<0.01）； compared with the M group， the BMSC and BMSCM2 groups had significant reductions in the mRNA expression levels of EpCam， Sox9， CK7， and CK19 （P<0.05） and significant increases in the mRNA expression levels of HNF-4α and Alb （P<0.05）， and compared with the BMSC group， the BMSCM2 group had significant reductions in the mRNA expression levels of EpCam and CK19 （P<0.05） and significant increase in the expression level of HNF-4α （P<0.05）. ConclusionM2-BMDMs can enhance the therapeutic effect of BMSCs on CCl4/2-AAF-induced liver cirrhosis in rats， which provides new ideas for further improving the therapeutic effect of BMSCs on liver cirrhosis.

BACKGROUND:The expression efficiency of recombinant adeno-associated virus serotype 9(rAAV9)carrying the macrophage-specific promoter synthetic promoter 146-C1(SP146-C1)and the exogenous gene vascular endothelial growth factor C(VEGFC)in atherosclerosis is uncertain. OBJECTIVE:To investigate the expression efficiency of rAAV9-SP146-C1-VEGFC in atherosclerotic mice and its effect on lymphangiogenesis. METHODS:Thirty ApoE-/-mice were fed high-fat diet for 12 weeks to establish atherosclerosis models and were randomly divided into six groups,five in each group:7-,14-,21-,28-,and 35-day transfection groups and control group.The mice in the transfection groups were transfected with 5.0×1011 vg rAAV9-SP146-C1-VEGFC by caudal vein injection.In the control group,the mice were injected with the same amount of control virus rAAV9-SP146-C1-Scramble.Animals in the first five groups were killed under anesthesia at 7,14,21,28 and 35 days after transfection,respectively,and those in the control group were killed under anesthesia at 7 days.Serum,femur,tibia,heart and aorta tissue samples were collected and retained in each group.The femur and tibia of mice in each group were used to extract bone marrow-derived macrophages.The gene expression of vascular endothelial growth factor C(VEGFC),vascular endothelial growth factor receptor 3(VEGFR3),Podoplanin and lymphatic vessel endothelial hyaluronan receptor-1(LYVE-1)in bone marrow-derived macrophages and the aorta were detected by RT-qPCR.VEGFC protein expression levels in bone marrow-derived macrophages and the aorta were detected by western blot,serum level of VEGFC was detected by ELISA,and VEGFC expression in the aortic sinus and LYVE-1 expression around the aorta and in the myocardium was detected by immunofluorescence. RESULTS AND CONCLUSION:The serum level of VEGFC,the mRNA expression of VEGFC,VEGFR3,Podoplanin,and LYVE-1 in bone marrow-derived macrophages and the aorta,the protein expression of VEGFC in bone marrow-derived macrophages,and the fluorescence intensity of VEGFC in aortic sinus plaques were significantly increased in the 7-day transfection group compared with the control group(P＜0.05,P＜0.01).Serum VEGFC level of mice transfected with rAAV9-SP146-C1-VEGFC gradually increased with time and began to decrease at 28 days.mRNA levels of VEGFC,VEGFR3,Podoplanin and LYVE-1 in mouse aorta and bone marrow-derived macrophages,VEGFC protein level in bone marrow-derived macrophages,VEGFC fluorescence intensity in aortic sinus plaques,LYVE-1 fluorescence intensity around the aortic sinus and in the myocardium gradually increased with time(P＜0.05).In addition,the mRNA level of LYVE-1 in the aorta and the fluorescence intensity of LYVE-1 around the aortic sinus and in the myocardium were the highest at 28 days(P＜0.05),and gradually decreased(P＜0.05).The expression of the other indicators reached the peak at 21 days.To conclude,rAAV9-SP146-C1-VEGFC could effectively transfect bone marrow-derived macrophages and promote lymphatic hyperplasia in atherosclerotic mice.

Methods@#This study enrolled 51 patients with LDK out of 382 patients with adult degenerative spinal deformity. Baseline information was reviewed including demographic data and complications. Sagittal spinopelvic alignments and global imbalance parameters were assessed on full-length X-ray images of the spine. Muscularity and the fatty infiltration area of the ES and multifidus (MF) were measured at the L4/5 level on preoperative magnetic resonance image to evaluate the lumbar erector muscle atrophy. Stratification by sagittal vertical axis (SVA) was performed: group 1 with SVA 100 mm, and these groups were compared. Spearman correlation and multivariable logistic regression analyses were performed to analyze and define risk factors of postoperative proximal junctional kyphosis (PJK). @*Results@#Group 2 had lower ES and MF muscularity than group 1. ES muscularity correlated with SVA (r=−0.510, p<0.003), lumbar lordosis (r=−0.415, p<0.018), and postoperative PJK (r=−0.508, p<0.022). MF muscularity did not correlate with the above parameters. Multivariable logistic regression analysis verified ES muscularity (odds ratio [OR], 0.001; p<0.039) and SVA (OR, 1.034; p<0.048) as the risk factors for postoperative PJK. @*Conclusions@#ES atrophy, besides the MF, is an important predictor in distinguishing decompensated LDK from well-compensated ones. It plays an important role in compensatory mechanism, not only correlates with global sagittal imbalance but also ties to PJK after deformity corrective surgery.

Background/Aims@#Cholestatic liver diseases including primary biliary cholangitis (PBC) are associated with active hepatic fibrogenesis, which ultimately progresses to cirrhosis. Activated hepatic stellate cells (HSCs) are the main fibrogenic effectors in response to cholangiocyte damage. JCAD regulates cell proliferation and malignant transformation in nonalcoholic steatoheaptitis-associated hepatocellular carcinoma (NASH-HCC). However, its participation in cholestatic fibrosis has not been explored yet. @*Methods@#Serial sections of liver tissue of PBC patients were stained with immunofluorescence. Hepatic fibrosis was induced by bile duct ligation (BDL) in wild-type (WT), global JCAD knockout mice (JCAD-KO) and HSC-specific JCAD knockout mice (HSC-JCAD-KO), and evaluated by histopathology and biochemical tests. In situ-activated HSCs isolated from BDL mice were used to determine effects of JCAD on HSC activation. @*Results@#In consistence with staining of liver sections from PBC patients, immunofluorescent staining revealed that JCAD expression was identified in smooth muscle α-actin (α-SMA)-positive fibroblast-like cells and was significantly up-regulated in WT mice with BDL. JCAD deficiency remarkably ameliorated BDL-induced hepatic injury and fibrosis, as documented by liver hydroxyproline content, when compared to WT mice with BDL. Histopathologically, collagen deposition was dramatically reduced in both JCAD-KO and HSC-JCAD-KO mice compared to WT mice, as visualized by Trichrome staining and semi-quantitative scores. Moreover, JCAD deprivation significantly attenuated in situ HSC activation and reduced expression of fibrotic genes after BDL. @*Conclusions@#JCAD deficiency effectively suppressed hepatic fibrosis induced by BDL in mice, and the underlying mechanisms are largely through suppressed Hippo-YAP signaling activity in HSCs.

OBJECTIVE@#This study aimed to investigate the effect and underlying mechanism of Fructus lycii in improving exercise fatigue.@*METHODS@#A network pharmacological approach was used to explore potential mechanisms of action of Fructus lycii. Skeletal muscle C2C12 cells and immunofluorescence were employed to verify the effect and mechanism of the representative components in Fructus lycii predicted by network pharmacological analysis.@*RESULTS@#Six potential active components, namely quercetin, β-sitosterol, stigmasterol, 7-O-methylluteolin-6-C-beta-glucoside_qt, atropine, and glycitein, were identified to have potency in improving exercise fatigue via multiple pathways, such as the PI3K-Akt, neuroactive ligand-receptor interaction, IL-17, TNF, and MAPK signaling pathways. The immunofluorescence results indicated that quercetin, a significant active component in Fructus lycii, increased the mean staining area of 2-NBDG, TMRM, and MitoTracker, and decreased the area of CellRox compared to the control. Furthermore, the protein expression levels of p-38 MAPK, p-MAPK, p-JNK, p-PI3K, and p-AKT markedly increased after quercetin treatment.@*CONCLUSION@#Fructus lycii might alleviate exercise fatigue through multiple components and pathways. Among these, quercetin appears to improve exercise fatigue by enhancing energy metabolism and reducing oxidative stress. The PI3K-AKT and MAPK signaling pathways also appear to play a role in this process.

ObjectiveTo explore the clinical effect of Tiaoxin formula in the treatment of patients with coronary heart disease and anxiety/depression and its impact on serum levels of 5-hydroxytryptamine （5-HT）， β- thromboglobulin （β-TG） and myeloperoxidase （MPO）. MethodA total of 66 patients with coronary heart disease and anxiety/depression were randomly divided into the Tiaoxin formula group and Deanxit group， 33 cases in each group. Both groups were given fundamental western treatment for coronary heart disease. Additionally， the Deanxit group was treated with flupentixol and melitracen tablets and the Tiaoxin formula group was treated with Tiaoxin Formula. The treatment lasted 8 weeks. Before and after treatment， the changes of clinical efficacy， Patient Health Questionnaire （PHQ-9）， Generalized Anxiety Disorder （GAD-7） scale， Seattle Angina Questionnaire （SAQ）， heart rate variability， and serum 5-HT， β-TG and MPO levels， and incidence of adverse reactions in the two groups were observed. ResultThere was no significant difference in the baseline indexes of patients in the two groups， and thus the two groups were comparable. After treatment for 8 weeks， the total effective rate for traditional Chinese medicine （TCM） syndromes in the Tiaoxin Formula group was 87.88% （29/33） higher than 63.64% （21/33） in the Deanxit group （Z=-2.653， P<0.05）. Compared with those before treatment， the PHQ-9 and GAD-7 scores of the two groups were decreased at week 4 and 8 of treatment （P<0.05）， and there was no statistical difference between two groups. And the SAQ dimension scores of the two groups were increased at week 4 and 8 of treatment （P<0.05）. Compared with the Deanxit group， the Tiaoxin Formula group had elevation in two dimension scores： Physical limitation and angina stability （P<0.05）. Compared with the conditions before treatment， the serum 5-HT level in the two groups were increased， while the β-TG and MPO levels were lowered （P<0.05）， and there was no distinct difference between two groups. In addition， the standard deviation of normal-to-normal intervals （SDNN） and standard deviation of average normal-to-normal intervals （SDANN） of the heart rate variability in the Tiaoxin formula group were elevated after treatment （P<0.05）， which were more significant than those of the Deanxit group （P<0.05）. During the treatment period， the incidence of adverse drug reactions in the Tiaoxin formula group was lower than that in the Deanxit group （P<0.05）， and no adverse events were observed in the two groups. ConclusionTiaoxin formula was effective for the treatment of patients with coronary heart disease accompanied by anxiety and depression， which improved the clinical symptoms， increased serum 5-HT levels， and decreased serum β-TG and MPO levels， and had few adverse reactions and high safety for patients， showing a high clinical value.

ObjectiveTo compare the outcomes in controlled ovarian stimulation （COH） and fresh embryo transfer between women with and those without a high basal luteinizing hormone （bLH） level in polycystic ovary syndrome （PCOS）. MethodsThe clinical data of PCOS patients at the Reproductive Medicine Center of the Sixth Hospital of Sun Yat-sen University from January 2015 to December 2021 were retrospectively analyzed. They were divided into the high group （LH≥10 U/L） and normal group （LH<10 U/L） according to the bLH levels. The results of COH and pregnancy outcomes after fresh transfer were compared， including gonadotropin （Gn） initiation dose， Gn duration， total Gn dose， number of oocytes obtained， two pronuclei （2PN） rate， available embryos rate， high-quality embryos rate， blastocyst formation rate， human chorionic gonadotrophin （HCG） positive rate， clinical pregnancy rate （CPR）， spontaneous abortion rate （SAR）， ongoing pregnancy rate （OPR） and live birth rate （LBR）. The differences in hormonal trends during COH were also analyzed. ResultsThere were no statistically significant differences in age， body mass index， anti-Mullerian hormone， and type of infertility between the two groups. Compared with the normal group， the Gn initiation dose and Gn duration were not statistically significant （P>0.05）， while the total Gn dose was significantly lower （P<0.001） in the high group. The number of oocytes retrieved， 2PN rate， available embryos rate， high-quality embryos rate， and blastocyst formation rate were comparable between the two groups （all P>0.05）. After fresh embryo transfer， they had similar pregnancy outcomes in the HCG positive rate， CPR， SAR， OPR and LBR （all P > 0.05）. ConclusionsIn patients with PCOS， high bLH levels do not affect COH or pregnancy outcomes in fresh transfer cycles. Further studies are needed to determine whether LH levels need to be lowered prior to COH and whether frozen-all strategy is required in patients with elevated bLH levels.

Abstract@#Allergic diseases can occur in all systems of the body, covering the whole life cycle, from children to adults and to old age, can be lifelong onset and even fatal in severe cases. Children account for the largest proportion of the victims of allergic disease, Children s allergies start from scratch, ranging from mild to severe, from less to more, from single to multiple systems and systemic performance, so the prevention and treatment of allergic diseases in children is of great importance, which can not only prevent high risk allergic conditions from developing into allergic diseases, but also further block the process of allergy. At present, there is no consensus on the management system of allergic children in kindergartens and primary schools. The "Consensus on Allergy Management and Prevention in Kindergartens and Primary Schools", which includes the organizational structure, system construction and management of allergic children, provides evidence informed recommendations for the long term comprehensive management of allergic children in kindergartens and primary schools, and provides a basis for the establishment of the prevention system for allergic children.

【Objective】 To explore the relationship between the storage time of leukodepleted red blood cells and transfusion adverse reactions by analyzing the occurrence of transfusion adverse reactions of patients after leukodepleted red blood cells transfusion from four hospitals. 【Methods】 By using the electronic medical record management system, the collection and transfusion dates of leukodepleted red blood cells from four hospitals in Enshi Prefecture from 2018 to 2022, as well as the information on transfusion adverse reactions, were retrieved. 【Results】 From 2018 to 2022, a total of 697 61 bags of leukodepleted red blood cells were transfused in four hospitals, resulting in 166 cases of transfusion adverse reactions, among which 93 were allergic reactions, 63 were non hemolytic febrile reactions, and 10 were others, with a total incidence rate of transfusion adverse reactions at 0.24%. The average storage time of leukodepleted red blood cells with and without transfusion adverse reactions was (20.25±6.31) and (19.88±5.50) days, respectively. With a storage time of 7 days as the threshold, the incidence of transfusion adverse reactions was the lowest for a storage time of 15~21 days. The incidence of transfusion adverse reactions of leukodepleted red blood cells in two groups (with storage days ≤21 days and >21 days) was not statistically significant(P>0.05). 【Conclusion】 Allergic reactions were the main type of transfusion adverse reaction caused by leukodepleted red blood cells, and the incidence of transfusion adverse reactions decreased and then increased with the prolongation of the storage time of leukodepleted red blood cells. There was no significant difference in the incidence of transfusion adverse reactions with leukodepleted red blood cells stored for ≤ 21 days and >21 days.

MethodsA total of 302 adolescents with major depressive disorder in Department of Psychosomatic Medicine of Deyang People's Hospital from January to December 2020 and met the Diagnostic and Statistical Manual of Mental Disorders， fifth edition （DSM-5） clinical significance criterion for depressive disorder were enrolled. All individuals were assessed using Insomnia Severity Index （ISI）， Ruminative Response Scale （RRS） and Positive and Negative Suicide Ideation （PANSI）. Then the mediating effect of rumination in the relation between insomnia and suicidal ideation in adolescents with major depression disorder was analyzed using Process v3.2 model 4， and testified with the bias-corrected non-parametric percentile Bootstrap method. ResultsISI scores in adolescents with major depression disorder were positively correlated with PANSI score （r=0.400， P<0.01）， and were positively correlated with RRS total score， obsessive thinking and introspection factor score （r=0.378， 0.360， 0.333， P<0.01）. RRS score was also positively correlated with PANSI score （r=0.292， P<0.01）. Rumination exerted a partial mediating effect on the relationship between insomnia and suicidal ideation （β=0.174， 95% CI： 0.098~0.261）. ConclusionThe relationship between insomnia and suicidal ideation in adolescents with depressive disorder is partially mediated by rumination， additionally， insomnia can affect suicidal ideation in adolescents with depressive disorder both directly and indirectly through rumination.
RÉSUMÉ
OBJECTIVE@#To investigate the value of using MDM2 amplification probe and DDIT3 dual-color, break-apart rearrangement probe fluorescence in situ hybridization (FISH) technique in the diagnosis of liposarcoma.@*METHODS@#In the study, 62 cases of liposarcoma diagnosed in Peking University First Hospital from January 2015 to December 2019 were analysed for clinicopathological information. Of these 62 cases of liposarcoma, all were analysed for MDM2 amplification and 48 cases were analysed for DDIT3 rearrangement using a FISH technique. Our study aimed to evaluate the status of MDM2 and DDIT3 by FISH in liposarcoma and correlate it with diagnosis of different subtypes of liposarcoma. The subtypes of liposarcoma were classified according to the FISH results, combined with the relevant clinicopathological features.@*RESULTS@#The patients aged 31-89 years (mean: 59 years) with a 1.75:1 male to female ratio. Histologically, there were 20 cases of atypical lipomatous tumour/well-differentiated liposarcoma (ALT/WDLPS), 26 cases of dedifferentiated liposarcoma (DDLPS), 13 myxoid liposarcoma (MLPS) and 3 pleomorphic liposarcoma (PLPS). Tumors with DDLPS (23/26) and WDLPS (8/20) were localized retroperitoneally, while both tumours of MLPS and PLPS were localized extra-retroperitoneally, and the difference of sites among the four subtypes of liposarcoma was statistically significant (P < 0.05). Histologically, varied mucoid matrix could be observed in the four subtypes of liposarcoma, and the difference was statistically significant (P < 0.05). MDM2 gene amplification was demonstrated in all cases of ALT/WDLPS and DDLPS (100%, 20/20 and 26/26 respectively); DDIT3 gene rearrangement was noted only in MLPS (100%, 13/13); most cases of DDLPS (96.2%, 25/26) and ALT/WDLPS (83.3%, 5/6, 6 cases selected for detection) demonstrated the picture of amplification of the DDIT3 telomeric tag. According to the instructions of DDIT3 break-apart rearrangement probe, the 5' telomere probe and 3' centromere probe spanned but did not cover the DDIT3 gene itself, on the contrary, the 5' telomere probe covered the CDK4 gene, while the DDIT3 and CDK4 gene were located adjacent to each other on chromosome, therefore, when the amplification signal appeared on the telomeric tag of the DDIT3 rearrangement probe, it indeed indicated the CDK4 gene amplification rather than the DDIT3 gene rearrangement. Then the 10 cases with DDIT3 telomeric tag amplification were selected for CDK4 and DDIT3 gene amplification probe FISH tests, and all the cases showed CDK4 gene amplification (100%, 10/10) and two of the 10 cases demonstrated co-amplification of CDK4 and DDIT3 (20%, 2/10); DDIT3 polysomy detected by DDIT3 gene rearrangement probe was found in 1 case of DDLPS and 2 cases of PLPS (66.7%, 2/3) with morphology of high-grade malignant tumour and poor prognosis.@*CONCLUSION@#Our results indicate that a diagnosis of different subtype liposarcoma could be confirmed based on the application of MDM2 and DDIT3 FISH, combined with clinicopathological findings. It is also noteworthy that atypical signals should be correctly interpreted to guide correct treatment of liposarcomas.
