Abstract
Endometrial cancer (EC), the second most common malignancy in the female reproductive system, has garnered increasing attention for its genomic heterogeneity, but understanding of its metabolic characteristics is still poor. We explored metabolic dysfunctions in EC through a comprehensive multi-omics analysis (RNA-seq datasets from The Cancer Genome Atlas [TCGA], Cancer Cell Line Encyclopedia [CCLE], and GEO datasets; the Clinical Proteomic Tumor Analysis Consortium [CPTAC] proteomics; CCLE metabolomics) to develop useful molecular targets for precision therapy. Unsupervised consensus clustering was performed to categorize EC patients into three metabolism-pathway-based subgroups (MPSs). These MPS subgroups had distinct clinical prognoses, transcriptomic and genomic alterations, immune microenvironment landscape, and unique patterns of chemotherapy sensitivity. Moreover, the MPS2 subgroup had a better response to immunotherapy. Finally, three machine learning algorithms (LASSO, random forest, and stepwise multivariate Cox regression) were used for developing a prognostic metagene signature based on metabolic molecules. Thus, a 13-hub gene-based classifier was constructed to predict patients' MPS subtypes, offering a more accessible and practical approach. This metabolism-based classification system can enhance prognostic predictions and guide clinical strategies for immunotherapy and metabolism-targeted therapy in EC.

Abstract
OBJECTIVES To report the results of a mesh-less laparoscopic extraperitoneal linear suspension technique for the treatment of post-hysterectomy vaginal vault prolapse (PHVP). STUDY DESIGN A retrospective observational study was conducted collecting medical records of 41 patients with symptomatic PHVP treated between November 2017 to November 2019 in Gynecologic department of China-Japan Friendship Hospital. All patients had Pelvic Organ Prolapse Quantification (POP-Q) scores indicating stage 3-4 PHVP and underwent mesh-less laparoscopic extraperitoneal linear suspension.The primary outcome was the subjective satisfaction rate based on responses to validated questionnaires. The secondary outcomes were the objective anatomical cure rate based on POP-Q scores and complication rates. All listed parameters were determined before the surgery and at control examinations in 1 year and 3 years after the treatment. RESULTS The operation was completed successfully without serious complications in all patients. Mean operation time was 53.8 mins. Comparison of the scores by the questionnaires revealed a significant improvement in the quality of life in the postoperative period.The subjective satisfaction rates were 100 % (41/41) and 95 % (38/40) at 1 year and 3 years after surgery. The objective cure rates were 100 % (41/41) and 97.5 % (39/40) at 1 year and 3 years after surgery, respectively. During the follow-up, none of the patients experienced suture exposure, infection, chronic pelvic pain, or other related complications. CONCLUSION The mesh-less laparoscopic extraperitoneal linear suspension technique avoids the use of implantable synthetic mesh. It has been shown to lead to favorable postoperative outcomes, considerable patient contentment, and low complication rates. It offers a new, cost-effective treatment option for PHVP patients.

Abstract
BACKGROUND To evaluate the effect of esketamine combined with ropivacaine hydrochloride on the occurrence of postpartum depression (PPD) after labor analgesia under epidural analgesia pump and explore the possible mechanisms. METHODS A total of 120 women aged 24 to 36 years old who underwent labor analgesia by epidural analgesia pump, with American Society of Anesthesiologists (ASA) physical status II were enrolled. According to the formula of epidural analgesia pump, all participants were randomly divided into two groups: esketamine group (Group E) and control group (Group C). Epidural anaesthesia were operated in all women between L2 and L3 after cervical dilation up to 2 ~ 3 cm. After successful puncture, the epidural catheter was placed 3.5 cm toward the head and 1% lidocaine was injected for 3 ml. The epidural analgesia pump was connected. Esketamine (0.2 mg/kg) combined with 0.75% ropivacaine hydrochloride (20 ml) were diluted by normal saline up to 100 ml in Group E, when only the equal dose of ropivacaine hydrochloride was used in Group C. The visual analogue scale (VAS) before analgesia (T1), 5 (T2), 10 (T3) and 20 (T4) minutes after analgesia were measured. The duration of the first and second stage of labor, the Apgar score of fetus at delivery, postpartum hemorrhage, consumption of esketamine and ropivacaine were recorded. The incidence of PPD was recorded at 1 week and 6 weeks after delivering. The occurrence of side effects such as nausea and vomiting, dizziness, and nightmares were also recorded for 48 h after delivering. The levels of leptin, norepinephrine(NE), and epinephrine(E) in the peripheral venous blood were measured before labor analgesia and at 24 h, 1 week, and 6 weeks after delivering. RESULTS Compared with Group C, the VAS score at T2, T3 and T4 were significantly lower in Group E (P < 0.01). Compared with Group C, the incidence of PPD was significantly lower at 1 week and 6 weeks after delivering in Group E (P < 0.01). Compared with Group C, the levels of leptin were significantly higher at 24 h and 1 week after delivering in Group E (P < 0.01), while NE and E (P < 0.01) were lower at the same time (P < 0.01). There were no significant difference of the duration of the first and second stage of labor, the Apgar score of fetus at delivery, postpartum hemorrhage, consumption of ropivacaine and the side effects for 48 h after delivering between the two groups. CONCLUSION Esketamine combined with ropivacaine hydrochloride used in labor analgesia can significantly reduce the incidence of postpartum depression after delivering without increasing related side effects, which may be related to the regulation of leptin, norepinephrine, and epinephrine in the serum.

Abstract
BACKGROUND The study was designed to investigate effects of single intravenous injection of esketamine on the incidence of postpartum depression (PPD) after labor analgesia and explore the potential mechanisms. METHODS A total of 120 women who underwent labor analgesia by epidural analgesia pump were enrolled and divided into two groups randomly. Esketamine at a dose of 0.2 mg/kg was intravenously injected after fetal disengagement in the test group and placebo was administered in the control group. The occurrence of PPD and side effects after delivery were recorded. Some indicators related to stress and inflammation were measured before labor analgesia and at 24 h, 1 week, and 6 weeks after delivery in this study. Data were analyzed by independent t-test, repeated measures analysis of variance and Chi-square test in SPSS software (version 25.0). It was considered statistically significant since a p value less than 0.05. RESULTS The incidence of PPD was significantly decreased both for one week and six weeks after delivery by using of esketamine (3.4% vs. 15.3%, p = 0.004 and 5.2% vs. 18.6%, p = 0.006, respectively). There were also significant differences between the stress and inflammation-related indicators in different time points in this study, while the side effects for 48 h after delivery were similar between the two groups. CONCLUSIONS Single intravenous injection of esketamine after delivery in participants underwent labor analgesia can decrease the occurrence of postpartum depression for one week and six weeks after delivery, while the side effects were not increased. The antidepressant effects of esketamine may be related to the reduction of stress response and inflammation.

Abstract
BACKGROUND Window-of-opportunity (WOO) studies provide insights into the clinical activity of new drugs in breast cancer. METHODS AMEERA-4 (NCT04191382) was a WOO study undertaken to compare the pharmacodynamic effects of amcenestrant, a selective estrogen receptor degrader, with those of letrozole in postmenopausal women with newly diagnosed, operable estrogen receptor-positive, human epidermal growth factor receptor 2-negative (ER+/HER2-) breast cancer. Women were randomized (1:1:1) to receive amcenestrant 400 mg, amcenestrant 200 mg, or letrozole 2.5 mg once daily for 14 days before breast surgery. The primary endpoint was change in Ki67 between baseline and Day 15 (i.e., day of surgery). RESULTS Enrollment was stopped early because of slow recruitment, in the context of the COVID-19 pandemic. The modified intent-to-treat population consisted of 95 study participants with baseline and post-treatment Ki67 values, whereas the safety population included 104 participants who had received at least one dose of study medication. Relative change from baseline in Ki67 was - 75.9% (95% confidence interval [CI] - 81.9 to - 67.9) for amcenestrant 400 mg, - 68.2% (- 75.7 to - 58.4) for amcenestrant 200 mg, and - 77.7% (- 83.4 to - 70.0) for letrozole (geometric least-squares mean [LSM] estimates). Absolute change in ER H-score from baseline (LSM estimate) was - 176.7 in the amcenestrant 400 mg arm, - 202.9 in the amcenestrant 200 mg arm, and - 32.5 in the letrozole arm. There were no Grade ≥ 3 treatment-related adverse events. CONCLUSIONS Both amcenestrant and letrozole demonstrated antiproliferative activity in postmenopausal women with previously untreated, operable ER+/HER2- breast cancer and had good overall tolerability.

Abstract
IMPORTANCE Venous thromboembolism (VTE) is closely relevant to head and neck cancer (HNC) prognosis, but little data exist on the risk prediction of VTE in patients with HNC. OBJECTIVE To study the risk factors regarding VTE in HNC patients and construct a nomogram model for its prediction. DESIGN, SETTING, AND PARTICIPANTS A cross-sectional retrospective study was implemented to comparatively analyze 220 HNC patients from January 2018 to December 2021. The Lasso algorithm was used to optimize the selection of variables. A nomogram model for predicting HNC-associated VTE was established using multivariate logistic regression analysis. Internal validation of the model was performed by bootstrap resampling (1000 times). Calibration plot and decision curve analysis (DCA) were applied to evaluate the calibration capability of the prediction model. MAIN OUTCOME AND MEASURE The demographics, medical history, blood biochemical indicators, and modalities of treatment were included for analysis. RESULTS The incidence of HNC-associated VTE was 2.8% (55/1967) in authors' affiliation. Five variables of risk factors, including surgery, radiochemotherapy, D-dimer, aspartate transaminase, and globulin, were screened and selected as predictors by Lasso algorithm. A prediction model that incorporated these independent predictors was developed and presented as the nomogram. The model showed good discrimination with a C-index of 0.972 (95% CI: 0.934-0.997), and had an area under the receiver operating characteristic curve value of 0.981 (p < 0.001, 95% CI: 0.964-0.998). The calibration curve displayed good agreement of the predicted probability with the actual observed probability for HNC-associated VTE. The DCA plot showed that the application of this nomogram was associated with net benefit gains in clinical practice. CONCLUSIONS AND RELEVANCE The high-performance nomogram model developed in this study may help early diagnose the risk of VTE in HNC patients and to guide individualized decision-making on thromboprophylaxis.

Abstract
Osteoarthritis (OA) is a degenerative joint disease involving cartilage. Exosomes derived from Mesenchymal stem cells (MSCs) therapy improves articular cartilage repair, but subcutaneous fat (SC) stromal cells derived exosomes (MSCsSC-Exos), especially engineering MSCsSC-Exos for drug delivery have been rarely reported in OA therapy. This objective of this study was to clarify the underlying mechanism of MSCsSC-Exos on cartilage repair and therapy of engineering MSCsSC-Exos for drug delivery in OA. MSCsSC-Exos could ameliorate the pathological severity degree of cartilage via miR-199a-3p, a novel molecular highly enriched in MSCsSC-Exos, which could mediate the mTOR-autophagy pathway in OA rat model. Intra-articular injection of antagomiR-199a-3p dramatically attenuated the protective effect of MSCsSC-Exos-mediated on articular cartilage in vivo. Furthermore, to achieve the superior therapeutic effects of MSCsSC-Exos on injured cartilage, engineering exosomes derived from MSCsSC as the chondrocyte-targeting miR-199a-3p delivery vehicles were investigated in vitro and in vivo. The chondrocyte-binding peptide (CAP) binding MSCsSC-Exos could particularly deliver miR-199a-3p into the chondrocytes in vitro and into deep articular tissues in vivo, then exert the excellent protective effect on injured cartilage in DMM-induced OA mice. As it is feasible to obtain human subcutaneous fat from healthy donors by liposuction operation in clinic, meanwhile engineering MSCsSC-Exos to realize targeted delivery of miR-199a-3p into chondrocytes exerted excellent therapeutic effects in OA animal model in vivo. Through combining MSCsSC-Exos therapy and miRNA therapy via an engineering approach, we develop an efficient MSCsSC-Exos-based strategy for OA therapy and promote the application of targeted-MSCsSC-Exos for drug delivery in the future.

Abstract
BACKGROUND Laparoscopic surgery has been a milestone for minimally invasive surgeries. But safe removal of large uterine tissue is a challenge for minimally invasive procedures, and there still exists concern about the dissemination of benign or occult malignant uterine tissue during the use of the morcellator. Different tissue containment systems have been used in laparoscopic power morcellation. However, a risk of leakage still exists in clinical practice. In this study, we aimed to evaluate leakage and tissue dissemination associated with a new detachable multi-hard-port containment system for tissue removal during laparoscopic myomectomy morcellation. METHODS Beef tongue specimens were stained with methylene blue solution and morcellated in a plastic trainer box under laparoscopic guidance. The morcellation test in vitro conditions comprised two different containment systems to simulate laparoscopic power morcellation, specifically a polyurethane bag with two pipes (control group) and a detachable multi-hard-port containment system (experimental group). Insufflation pressure was set at 14 mmHg. Three methods are used to detect the leakage The procedure times were recorded. Thirty trials were performed using a multi-port approach and the two tissue containment systems. RESULTS The leakage rate was 0.03% (n = 30) for the experimental group and 26.6% (n = 30) for the control group (p < 0.005). Morcellation time was significantly shorter in the experimental group than in the control group (p < 0.001). Median bag introduction time was shorter in the experimental group than in the control group; however, removal time differences were not significant. CONCLUSIONS This study quantified the low leakage rate during morcellation and the improved convenience of operation provided by a new tissue containment system.

Abstract
BACKGROUNDS To observe the effect of using mild intraoperative hyperventilation on the incidence of postlaparoscopic shoulder pain (PLSP) in patients undergoing laparoscopic sleeve gastrectomy. METHODS Eighty patients undergoing laparoscopic sleeve gastrectomy, aged 22 to 36 years, with American Society of Anesthesiologists grade I or II, were divided into 2 groups according to method of random number table. A mild hyperventilation was used in group A with controlling pressure of end-tidal carbon dioxide (PETCO2) of 30 to 33 mm Hg, while conventional ventilation was used in group B with PETCO2 35 to 40 mm Hg during the operation. The incidence and severity of PLSP, dosage of remedial analgesia and adverse reactions such as nausea and vomiting at 12, 24, 48, 72 hours and 1 week after surgery were recorded. Arterial blood gas was recorded before anesthesia induction, 20 minutes after pneumoperitoneum, during suture skin, and 24 hours after surgery. RESULTS Compared with 12, 24, 48, and 72 hours after operation, the incidence of PLSP at 1 week decreased significantly (P < .01). Compared with group B, the incidence of PLSP, pain score, and dosage of remedial analgesic at 12, 24,48, 72 hours, and 1 week after surgery were significantly decreased (P < .01). There was no significant difference between the 2 groups in arterial blood gas analysis before anesthesia induction, 20 minutes after pneumoperitoneum, during suture skin, and 24 hours after surgery (P > .05). There were no significant difference of the occurrence of adverse reactions such as nausea and vomiting between the 2 groups within 1 week after surgery (P > .05). CONCLUSION Mild hyperventilation can reduce the incidence and severity of PLSP after laparoscopic sleeve gastrectomy without increasing the associated adverse effects.

Abstract
Although most endometrial cancer (EC) patients have a favorable prognosis, the overall survival (OS) of metastatic and recurrent EC could hardly be improved by the current chemoradiotherapy. We aimed to reveal the tumor microenvironment immune infiltration characteristics to elucidate the underlying mechanism of EC progression and guide clinical decisions. In the Cancer Genome Atlas (TCGA) cohort, Kaplan-Meier survival curves confirmed Tregs and CD8 T cells were prognosis-protective factors in OS of EC ( P <0.05). Weighted gene coexpression network analysis identified 2 gene modules closely correlated with Tregs and CD8 T-cell infiltration. We randomly split the TCGA EC cohort into the training and testing cohorts at a ratio of 7:3. An immune-related prognosis risk index (IRPRI), including NR3C1, E2F1, OTOG, TTK, PPP1R16B, and FOXP3, was established by univariate, Least Absolute Shrinkage and Selection Operator, and multivariate Cox regression with area under the curve >0.67. Distinct clinical, immune, and mutation characteristics existed between IRPRI groups by multiomics analysis. Cell proliferation and DNA damage repair-related pathways were activated, and immune-related pathways were inactivated in the IRPRI-high group. Furthermore, patients in the IRPRI-high group had lower tumor mutation burden, programmed death-ligand 1 expression, and Tumor Immune Dysfunction and Exclusion scores, indicating a poor response to immune checkpoint inhibitors therapy ( P <0.05), which was also validated in the TCGA testing cohort and independent cohorts, GSE78200, GSE115821, and GSE168204. Also, the higher mutation frequencies of BRCA1, BRCA2, and genes enrolled in homologous recombination repair in the IRPRI-low group predicted a good response to PARP inhibitors. Finally, a nomogram integrating the IRPRI group and prognosis significant clinicopathological factors for EC OS prediction was developed and validated with good discrimination and calibration.

Abstract
BACKGROUND Osteoarthritis (OA) is a highly degenerative joint disease, mainly companying with progressive destruction of articular cartilage. Adipose-derived stromal cells (ADSCs) therapy enhances articular cartilage repair, extracellular matrix (ECM) synthesis and attenuates joints inflammation, but specific mechanisms of therapeutic benefit remain poorly understood. This study aimed to clarify the therapeutic effects and mechanisms of ADSCs on cartilage damage in the keen joint of OA rat model. METHODS Destabilization of the medial meniscus (DMM) and anterior cruciate ligament transection (ACLT) surgery-induced OA rats were treated with allogeneic ADSCs by intra-articular injections for 6 weeks. The protective effect of ADSCs in vivo was measured using Safranin O and fast green staining, immunofluorescence and western blot analysis. Meanwhile, the miRNA-7-5p (miR-7-5p) expression was assessed by quantitative reverse transcription-polymerase chain reaction (qRT-PCR). The mechanism of increased autophagy with ADSCs addition through decreasing miR-7-5p was revealed using oligonucleotides, and adenovirus in rat chondrocytes. The luciferase reporter assay revealed the molecular role of miR-7-5p and autophagy related 4A (ATG4A). The substrate of mTORC1 pathway: (p-)p70S6 and (p-)S6 in OA models with ADSCs addition were detected by western blotting. RESULTS The ADSCs treatment repaired the articular cartilage and maintained chondrocytes ECM homeostasis through modulating chondrocytes autophagy in the OA model, indicators of the change of autophagic proteins expression and autophagic flux. Meanwhile, the increased autophagy induced by ADSCs treatment was closely related to the decreased expression of host-derived miR-7-5p, a negative modulator of OA progression. Functional genomics (overexpression of genes) in vitro studies demonstrate the inhibition of host-derived miR-7-5p in mediating the benefit of ADSCs administration in OA model. Then ATG4A was defined as a target gene of miR-7-5p, and the negative relation between miR-7-5p and ATG4A was investigated in the OA model treated with ADSCs. Furthermore, miR-7-5p mediated chondrocyte autophagy by targeting ATG4A in the OA model treated with ADSCs was confirmed with the rescue trial of ATG4A/miR-7-5p overexpression on rat chondrocyte. Finally, the mTORC1 signaling pathways mediated by host-derived miR-7-5p with ADSCs treatment were decreased in OA rats. CONCLUSIONS ADSCs promote the chondrocytes autophagy by decreasing miR-7-5p in articular cartilage by targeting ATG4A and a potential role for ADSCs based therapeutics for preventing of articular cartilage destruction and extracellular matrix (ECM) degradation in OA.

Abstract
BACKGROUND To compare the oncological outcomes of patients with FIGO 2018 stage IIIC cervical cancer (CC) involving different local tumor factors who underwent abdominal radical hysterectomy (ARH), neoadjuvant chemotherapy and radical surgery (NACT), or radical chemoradiotherapy (R-CT). METHODS Based on tumor staging, patients with stage IIIC were divided into T1, T2a, T2b, and T3 groups. Kaplan-Meier and Cox proportional hazards regression analysis were used to compare their overall survival (OS) and disease-free survival (DFS) of 5 years. RESULTS We included 4,086 patients (1,117, 1,019, 869, and 1,081 in the T1, T2a, T2b, and T3 groups, respectively). In the T1 group, NACT was correlated with a decrease in OS (hazard ratio [HR] = 1.631, 95% confidence interval [CI]: 1.150-2.315, P = 0.006) and DFS (HR = 1.665, 95% CI: 1.255-2.182, P < 0.001) than ARH. ARH and NACT were not correlated with OS (P = 0.226 and P = 0.921) or DFS (P = 0.343 and P = 0.535) than R-CT. In the T2a group, NACT was correlated with a decrease in OS (HR = 1.454, 95% CI: 1.057-2.000, P = 0.021) and DFS (HR = 1.529, 95% CI: 1.185-1.974, P = 0.001) than ARH. ARH and NACT were not correlated with OS (P = 0.736 and P = 0.267) or DFS (P = 0.714 and P = 0.087) than R-CT. In the T2b group, NACT was correlated with a decrease in DFS (HR = 1.847, 95% CI: 1.347-2.532, P < 0.001) than R-CT nevertheless was not correlated with OS (P = 0.146); ARH was not correlated with OS (P = 0.056) and DFS (P = 0.676). In the T3 group, the OS rates of ARH (n = 10), NACT (n = 18), and R-CT (n = 1053) were 67.5%, 53.1%, and 64.7% (P = 0.941), and the DFS rates were 68.6%, 45.5%, and 61.1%, respectively (P = 0.761). CONCLUSION R-CT oncological outcomes were not entirely superior to those of NACT or ARH under different local tumor factors with stage IIIC. NACT is not suitable for stage T1, T2a, and T2b. Nevertheless ARH is potentially applicable to stage T1, T2a, T2b and T3. The results of stage T3 require confirmation through further research due to disparity in case numbers in each subgroup.

Abstract
Career adaptability is a psychological resource for individuals to deal with career events, and it is a system of human-environment interaction. The components of the career adaptability concept are not independent of each other but rather an interactive network. The present study aims to shed light on the nomological network of career adaptability and the starting salary by investigating their indicators using network analysis to reveal their structural networks and interrelationships. In addition, we compared the similarities and differences between the networks of different gender groups. Results indicate that career adaptability directly connects to starting salary for graduates, and some indicators are the core factors that influence starting salary. Besides, the global structure of gender-specific networks is very similar. However, some differences have been detected, such as becoming curious about new opportunities is the male network's core, while the core of the female network is doing the right thing.

Abstract
OBJECTIVE We aimed to compare the 5-year oncological outcomes of laparoscopic/abdominal radical hysterectomy (LRH/ARH) in patients with cervical adenosquamous carcinoma at stage IA2 to IIA2 based on the 2009 or 2018 International Federation of Gynecology and Obstetrics (FIGO) staging criteria. METHODS Based on the clinical diagnosis and treatment of cervical cancer in China (Four C) database, Cox risk regression models were applied to analyze tumor prognosis treated with ARH/LRH in FIGO 2009 and 2018 IA2-IIA2 patients and stratified findings according to tumor diameter (≤4 and >4 cm subgroups). And to avoid bias, propensity score matching (PSM) was also used for the cohort study. RESULTS Based on FIGO 2009 staging criteria (n = 474), there was no significant difference between the ARH and LRH groups in 5-year disease-free survival (DFS) or overall survival (OS). Lymph node metastasis was a risk factor for 5-year DFS in this stage. After PSM, lymphovascular space invasion (LVSI) was an independent risk factor for 5-year OS in the tumors ≤4 cm subgroup. Based on FIGO2018 staging criteria (n = 322), cervical interstitial infiltration depth was an independent risk factor for 5-year OS in the total population and the tumor diameter ≤4 cm subgroup. CONCLUSIONS Laparoscopic surgery was not a risk factor affecting the oncologic prognosis of adenosquamous carcinoma of the cervix based on either FIGO 2009 or 2018 staging of stage IA2-IIA2. In addition, LRH may be considered for patients with early-stage cervical adenosquamous carcinoma.

Abstract
BACKGROUND To evaluate the effect of pre-administration of esketamine intraoperatively on the occurrence of postpartum depression after cesarean section under combined spinal-epidural anesthesia. METHODS A total of 120 women aged 24 to 36 years undergoing cesarean section by spinal-epidural anesthesia with American Society of Anesthesiologists physical status II were enrolled. According to the intraoperative use of esketamine, all participants were randomly divided into 2 groups: test group (group E) and control group (group C). Esketamine was administered intravenously at a dose of 0.2 mg/kg after the infant was delivered in group E and equal volume of normal saline was given in group C. The incidence of postpartum depression was recorded at 1 week and 6 weeks after the operation. The occurrence of adverse reactions such as postpartum bleeding, nausea and vomiting, drowsiness, and nightmares were also recorded at 48 hours after surgery. RESULTS Compared with group C, the incidence of postpartum depression was significantly lower at 1 week and 6 weeks after surgery in group E (P < .01). There was no significant difference of the adverse effects at 48 hours after the operation between the 2 groups. CONCLUSION Intravenous infusion of 0.2 mg/kg esketamine in women during cesarean section can significantly reduce the incidence of postpartum depression at 1 week and 6 weeks after surgery without increasing related adverse effects.

Role of hyperbaric oxygen therapy in PDGF-BB-mediated astrogliosis in traumatic brain injury rats associated with ERK1/2 signaling pathway inhibition. Eur J Med Res 2023; 28:99.

Abstract
BACKGROUND Hyperbaric oxygen (HBO) plays positive roles in the therapy of traumatic brain injury (TBI); however, the mechanism underlying its effects on TBI is largely unknown. The study aims to elucidate the molecular mechanism implicated with the interaction between platelet-derived growth factor-BB (PDGF-BB) and extracellular signal-regulated kinase 1/2 (ERK1/2) signaling pathway, which may play critical roles during HBO treatment both in the astrocyte scratching model in vitro and rat TBI model in vivo. METHODS Changes in neurological function and wound healing were evaluated using the neurological severity scores (NSS) scale, immunohistochemistry, western blotting, and qRT-PCR, respectively. RESULTS The results showed that PDGF-BBi (PDGB interfered with small RNA) dramatically improves neuronal viability in vitro when transfected into the scratched astrocytes derived from the cerebral cortex of neonatal rats. Moreover, in vivo experiments revealed that HBO therapy substantially elevated the NSS scores and simultaneously reduced the mortality in TBI rats, as indicated by the NSS scales. Notably, HBO therapy was found to possess the ability to inhibit glial cell proliferation, promote the regeneration of neurons and synapses, and ultimately facilitate the wound healing, as revealed by immunohistochemistry and glial scar formation found in TBI rats. Importantly, HBO markedly decreased the expression levels of PDGF-BB and ERK1/2. It can clearly be seen that downregulated PDGF-BB and ERK1/2 levels were corresponding with the status of significant amelioration of the therapeutic effect of HBO. Conversely, the upregulation of PDGF-BB and ERK1/2 levels was in line with the opposite effect. CONCLUSION It has been concluded that HBO therapy may play its active role in TBI treatment dependent on astrogliosis inhibition, which may be achieved by downregulating the ERK1/2 signaling pathway mediated by PDGF-BB.

Abstract
AIM The aim of this study was to identify the biological characteristics and potential roles of endometrial progenitor cells in the pathogenesis of endometriosis. BACKGROUND It is generally believed that progenitor cells in human endometrium are responsible for rapid endometrial regeneration. However, the biological characteristics and potential roles of the paired eutopic and ectopic endometrial progenitor cells in endometriosis remain unclear. OBJECTIVE This study intends to isolate the epithelial progenitor (EP) cells and endometrial mesenchymal stem cells (eMSCs) from the eutopic and ectopic endometria from endometriosis patients, further to reveal their features and functions respectively. METHODS The distributions of EP cells and eMSCs and the expression of steroid hormone receptors in the endometrium and endometriotic tissues were assessed by immunohistochemistry. EP cells and eMSCs were sorted from paired eutopic and ectopic endometria with epithelial cell adhesion molecule (EpCAM) magnetic beads. The clonogenicity, cell viability after being treated with estradiol and progesterone, and cell markers expression were evaluated with colony forming on Matrigel, CCK-8 and immunofluorescence staining, respectively. The differentially expressed genes (DEGs) were further identified with RNA sequencing. RESULTS SSEA-1- and PDGFRβ-positive cells were distributed in the epithelial and stromal layers. The ERβ staining was much more intense in endometriotic tissues, but PR expression was almost absent. The ectopic EP cells exhibit strong clonogenicity and ERβ expression but weak PR expression, leading to progesterone resistance. There are 12604 and 13242 DEGs revealed by RNA sequencing between eutopic and ectopic EP cells or eMSCs. GO and KEGG analyses revealed that the functions and pathways of DEGs enriched in cellular energy metabolism and regulation of the immune response, respectively. Additionally, ERβ targets were mainly enriched in ectopic EP cells. CONCLUSION Both EP cells and eMSCs may engage in ectopic lesion formation in endometriosis by modifying the metabolic mode and immune tolerance. These data not only help to understand the molecular mechanism of endometriosis but also could potentially contribute to the discovery of therapeutic targets for endometriosis.

Abstract
OBJECTIVE To present a novel totally enclosed protective device for tumor isolation in laparoscopic ovarian cystectomy. METHODS A retrospective study was conducted of 16 patients with unilateral ovarian teratoma in the Department of Obstetrics and Gynecology of the China-Japan Friendship Hospital. Laparoscopic surgery was performed with a totally enclosed protective device for tumor isolation, followed by a case series retrospective study. The indexes measured included size of cyst, rate of intraoperative rupture, duration of operation, amount of intraoperative blood loss, and postoperative length of stay in the hospital. An intact cyst resected in the device with no spillage seen indicated a successful surgery. RESULTS A total of 16 operations were performed successfully. The mean diameter of the cysts was 7.2 ± 1.4 cm. Of them, 12 (75%) had an intraoperative cyst rupture without spillage. The mean duration of surgery was 1.3 ± 0.1 h and the mean amount of intraoperative blood loss was 12.5 ± 3.2 ml. All postoperative histology tests showed benign cysts. The mean length of stay after surgery was 2.4 ± 0.5 days. No peritonitis-related symptoms or complaints were reported. CONCLUSION Laparoscopically assisted ovarian cystectomy with a totally enclosed protective device for tumor isolation was confirmed safe and feasible.

Abstract
BACKGROUND Oromaxillofacial carcinomas frequently result in serious tissue defect due to enlarged resection for treating their extensive invasion, which require challenging reconstruction. Three-dimensional (3D) printing is an advanced technology which has greatly promoted the progress of craniomaxillofacial reconstructive surgery. This present study aimed to investigate the advantages of anterolateral thigh (ALT) perforator flap manufactured by 3D printing fixed positioning guide template in curing oromaxillofacial defect. MATERIAL AND METHODS Twenty patients with oromaxillofacial defects resulted from severe primary malignant tumors were divided into experimental group assisted by digital technique (n=8) and controlled group conventionally aided by ultrasound (n=12). The therapeutic effectiveness, flap preparation time, amount of bleeding, deviation of perforator vessel location, aesthetic satisfaction of donor site, postoperative complications, adverse symptom of flap, and LEFS scores were compared. RESULTS For experimental group, flap preparation time was significantly shorter; and it has obviously less bleeding, minor deviation of perforator vessel location, and better aesthetic satisfaction of donor site (P<.001). There was no statistical difference in postoperative complications and LEFS scores between two groups (P>.05). CONCLUSIONS The study suggests 3D printing template of fixed positioning guide provides a brand-new method for orienting perforated vessels of ALT flap, which is more accurate in clinical application. It can improve the operative efficacy, and increase the successful rate of operation as well.

Abstract
Bone marrow stromal cells (BMSCs) have emerged as a potential therapy for sepsis, yet the underlying mechanisms remain unclear. In this study, we investigated the effects of BMSCs on serum inflammatory cytokines in a rat model of lipopolysaccharide (LPS)-induced sepsis. Sepsis was induced by intravenous injection of LPS, followed by transplantation of BMSCs. We monitored survival rates for 72 h and evaluated organ functions, histopathological changes, and cytokines expression. Sepsis rats showed decreased levels of white blood cells, platelets, lymphocyte ratio, and oxygen partial pressure, along with increased levels of neutrophil ratio, carbon dioxide partial pressure, lactic acid, alanine aminotransferase, and aspartate aminotransferase. Histologically, lung, intestine, and liver tissues exhibited congestion, edema, and infiltration of inflammatory cells. However, after BMSCs treatment, there was improvement in organ functions, histopathological injuries, and survival rates. Protein microarray analysis revealed significant changes in the expression of 12 out of 34 inflammatory cytokines. These findings were confirmed by enzyme-linked immunosorbent assay. Pro-inflammatory factors, such as interleukin-1β (IL-1β), IL-1α, tumor necrosis factor-α (TNF-α), tissue inhibitor of metal protease 1 (TIMP-1), matrix metalloproteinase 8 (MMP-8), Leptin, and L-selectin were upregulated in sepsis, whereas anti-inflammatory and growth factors, including IL-4, β-nerve growth factor (β-NGF), ciliary neurotrophic factor (CNTF), interferon γ (IFN-γ), and Activin A were downregulated. BMSCs transplantation led to a decrease in pro-inflammatory cytokines and an increase in anti-inflammatory and growth factors. We summarized relevant molecular signaling pathways that resulted from cytokines in BMSCs for treating sepsis. Our results illustrated that BMSCs could promote tissue repair and improve organ functions and survival rates in sepsis through modulating cytokine networks.

Abstract
Gastrointestinal colonization with carbapenem-resistant Enterobacteriaceae (CRE) is always a prerequisite for the development of translocated infections. Here, we sought to screen for fecal carriage of CRE and identify the risk factors for CRE colonization as well as subsequent translocated pneumonia in critically ill patients admitted to the intensive care unit (ICU) of a university hospital in China. We further focused on the intestinal flora composition and fecal metabolic profiles in CRE rectal colonization and translocated infection patients. Animal models of gastrointestinal colonization with a carbapenemase-producing Klebsiella pneumoniae (carbapenem-resistant K. pneumoniae [CRKP]) clinical isolate expressing green fluorescent protein (GFP) were established, and systemic infection was subsequently traced using an in vivo imaging system (IVIS). The intestinal barrier, inflammatory factors, and infiltrating immune cells were further investigated. In this study, we screened 54 patients hospitalized in the ICU with CRE rectal colonization, and 50% of the colonized patients developed CRE-associated pneumonia, in line with the significantly high mortality rate. Upon multivariate analysis, risk factors associated with subsequent pneumonia caused by CRE in patients with fecal colonization included enteral feeding and carbapenem exposure. Furthermore, CRKP colonization and translocated infection influenced the diversity and community composition of the intestinal microbiome. Downregulated propionate and butyrate probably play important and multiangle roles in regulating immune cell infiltration, inflammatory factor expression, and mucus and intestinal epithelial barrier integrity. Although the risk factors and intestinal biomarkers for subsequent infections among CRE-colonized patients were explored, further work is needed to elucidate the complicated mechanisms. IMPORTANCE Carbapenem-resistant Enterobacteriaceae have emerged as a major threat to modern medicine, and the spread of carbapenem-resistant Enterobacteriaceae is a clinical and public health problem. Gastrointestinal colonization by potential pathogens is always a prerequisite for the development of translocated infections, and there is a growing need to assess clinical risk factors and microbiological and intestinal characteristics to prevent the development of clinical infection by carbapenem-resistant Enterobacteriaceae.

Abstract
BACKGROUND The aim of this randomized double-blind placebo controlled clinical trial was to investigate the effects of different doses of esketamine combined with sufentanil for postoperative intravenous controlled analgesia after cesarean section and the incidence of postpartum depression. METHODS One hundred and sixty patients undergoing elective cesarean section, with a singleton term pregnancy and American Society of Anesthesiologists physical status II were selected. All patients were treated by a combined epidural with spinal anesthesia. They were randomly divided into 4 groups according to patient controlled intravenous analgesia formula. The consumption of sufentanil, times of effective press and remediate analgesia at 48 hours after cesarean section, incidence of postpartum depression (PPD) at 1 week and 6 weeks after the operation were recorded. RESULTS Comparison of cumulated dosage of sufentanil, times of effective press and rescue analgesia at 48 hours after operation: Group H was significantly lower than Group M, Group L, and Group C (P < .05), Group M significantly lower than group L and Group C (P < .05), and Group L significantly lower than Group C (P < .05). Comparison of the incidence of PPD at 1 week and 6 weeks later: Group H was significantly lower than Group M, Group L, and Group C (P < .01), Group M significantly lower than Group L and Group C (P < .01) and Group L significantly lower than Group C (P < .01). Compared with Group C, the incidence of nausea and vomiting was significantly reduced in Group H, Group M, and Group L (P < .05). CONCLUSION Esketamine combined with sufentanil used for patient controlled intravenous analgesia after elective cesarean section can reduce the consumption of sufentanil, improve postoperative analgesia, decrease the incidence of PPD at 1 week and 6 weeks and postoperative nausea and vomiting.

Abstract
Osteoarthritis (OA) is characterised by cartilage destruction; however, there are no specific drugs available for its treatment. Cartilage-derived stem/progenitor cells (CSPCs) are multipotent cells that play an essential role in cartilage renewal and may provide critical insights into the medical needs for OA treatment. However, alterations in cell function and fate of CSPCs during OA progression have seldom been analysed, especially at the single-cell level. Additionally, it has been reported that CSPCs can migrate to the cartilage injury area, although the mechanism of migration remains elusive. Thus, understanding the changing patterns of CSPCs in the pathological process of OA is important in the effort to develop stem cell therapy for OA. Here, we downloaded single-cell transcriptomic data of patients with OA from the Gene Expression Omnibus (GEO) database and performed unbiased clustering of the cells based on gene expression patterns using the Seurat package. Using common stem cell markers and chondrogenic transcription factors, we traced CSPCs throughout all stages of OA. We further explored the dynamics of CSPCs in OA progression and validated the single-cell RNA sequencing data in vitro using qPCR, immunofluorescence, and western blotting. Specifically, we primarily explored the heterogeneity of CSPCs at the single-cell level and found that it was closely associated with OA progression. Our results indicate significantly reduced chondrogenic differentiation capacity in CSPCs during the late stage of OA, while their proliferation capacity tended to increase. We also found that genes implicated in fibrosis, cell motility, and extracellular matrix remodelling were upregulated in CSPCs during the progression of OA. Our study revealed the dynamics of stem cells in OA progression and may inform the development of stem cell therapy for OA.

Abstract
BACKGROUND The linkage between IDO2 expression and cancer progression is still unclear, particularly in medullary thyroid carcinoma (MTC). Our purpose is to unveil the potential correlations between IDO2 status, clinical-pathological parameters, patients' prognosis, and the possible immunomodulatory functions in MTC. METHODS Immunohistochemical expression levels of IDO2 were evaluated in the resected MTC surgical specimens and corresponding lymph nodes. CD4 + T cell infiltration was also evaluated by immunohistochemical analysis in the MTC tissues. The association of the IDO2 expression level with clinicopathologic characteristics, overall survival (OS)/recurrence-free survival (RFS), and CD4 + T cell infiltration were retrospectively investigated. RESULTS High expression of IDO2 is closely associated with more aggressive clinicopathological features, such as multifocality, ETE, a higher pT stage and especially a higher pN stage. Moreover, a significant difference in RFS was observed between the IDO2-high and IDO2-low groups. IDO2 expression of lymph node tissues was significantly related to the metastasis status. Furthermore, we found that IDO2 expression is negatively correlated with CD4 + T cell infiltrations in MTC tissues. CONCLUSION The expression level of IDO2 is associated with aggressive characteristics and is predictive of poor prognosis in patients with MTC. Also, an interesting observation is that IDO2 involvement in MTC showed a moderate sexual dimorphism, of which female patients tend to be more affected by IDO2 status. Moreover, our results showed the potential immunomodulatory functions of IDO2. The close relationship between IDO2 and CD4 + T cell infiltration in the MTC microenvironment, together with its potential prognostic implications, makes it possible for IDO2 to serve as an alternative drug target in cancer immunotherapy and as a new prognostic tool.

Abstract
Background Hepatic fibrosis is a common pathologic stage in chronic liver disease development, which might ultimately lead to liver cirrhosis. Accumulating evidence suggests that adipose-derived stromal cells (ADSCs)-based therapies show excellent therapeutic potential in liver injury disease owing to its superior properties, including tissue repair ability and immunomodulation effect. However, cell-based therapy still limits to several problems, such as engraftment efficiency and immunoreaction, which impede the ADSCs-based therapeutics development. So, ADSCs-derived extracellular vesicles (EVs), especially for exosomes (ADSC-EXO), emerge as a promise cell-free therapeutics to ameliorate liver fibrosis. The effect and underlying mechanisms of ADSC-EXO in liver fibrosis remains blurred. Methods Hepatic fibrosis murine model was established by intraperitoneal sequential injecting the diethylnitrosamine (DEN) for two weeks and then carbon tetrachloride (CCl4) for six weeks. Subsequently, hepatic fibrosis mice were administrated with ADSC-EXO (10 μg/g) or PBS through tail vein infusion for three times in two weeks. To evaluate the anti-fibrotic capacity of ADSC-EXO, we detected liver morphology by histopathological examination, ECM deposition by serology test and Sirius Red staining, profibrogenic markers by qRT-PCR assay. LX-2 cells treated with TGF-β (10 ng/ml) for 12 h were conducted for evaluating ADSC-EXO effect on activated hepatic stellate cells (HSCs). RNA-seq was performed for further analysis of the underlying regulatory mechanisms of ADSC-EXO in liver fibrosis. Results In this study, we obtained isolated ADSCs, collected and separated ADSCs-derived exosomes. We found that ADSC-EXO treatment could efficiently ameliorate DEN/CCl4-induced hepatic fibrosis by improving mice liver function and lessening hepatic ECM deposition. Moreover, ADSC-EXO intervention could reverse profibrogenic phenotypes both in vivo and in vitro, including HSCs activation depressed and profibrogenic markers inhibition. Additionally, RNA-seq analysis further determined that decreased glutamine synthetase (Glul) of perivenous hepatocytes in hepatic fibrosis mice could be dramatically up-regulated by ADSC-EXO treatment; meanwhile, glutamine and ammonia metabolism-associated key enzyme OAT was up-regulated and GLS2 was down-regulated by ADSC-EXO treatment in mice liver. In addition, glutamine synthetase inhibitor would erase ADSC-EXO therapeutic effect on hepatic fibrosis. Conclusions These findings demonstrated that ADSC-derived exosomes could efficiently alleviate hepatic fibrosis by suppressing HSCs activation and remodeling glutamine and ammonia metabolism mediated by hepatocellular glutamine synthetase, which might be a novel and promising anti-fibrotic therapeutics for hepatic fibrosis disease.

Abstract
INTRODUCTION It is clinically challenging to differentiate the pathophysiological types of shock in emergency situations. Here, we evaluated the ability of a novel bedside ultrasound protocol (Tamponade/tension pneumothorax, Heart, Inferior vena cava, Respiratory system, Deep venous thrombosis/aorta dissection [THIRD]) to predict types of shock in the emergency department. METHODS An emergency physician performed the THIRD protocol on all patients with shock who were admitted to the emergency department. All patients were closely followed to determine their final clinical diagnoses. The kappa index, sensitivity, specificity, positive predictive value, and negative predictive value were calculated for the initial diagnostic impression provided by the THIRD protocol, compared with each patient's final diagnosis. RESULTS In total, 112 patients were enrolled in this study. The kappa index between initial impression and final diagnosis was 0.81 (95% confidence interval=0.73-0.89; P<0.001). For hypovolaemic, cardiogenic, distributive, and obstructive types of shock, the sensitivities of the THIRD protocol were 100%, 100%, 93%, and 100%, respectively; the sensitivity for a 'mixed' shock aetiology was 86%. The negative predictive value of the THIRD protocol for all five types of shock was ≥96%. CONCLUSION Initial diagnostic judgements determined using the THIRD protocol showed favourable agreement with the final diagnosis in patients who presented with undifferentiated shock. The THIRD protocol has great potential for use as a bedside approach that can guide the rapid management of undifferentiated shock in emergency settings, particularly for patients with obstructive, hypovolaemic, or cardiogenic shock.

Abstract
AbstractThe existence of Lactobacillus-led colonized bacteria in the endometrium of a healthy human has been reported in recent studies. Unlike the composition of the microbiome in the lower genital tract, that in the endometrium is different and closely associated with the physiological and pathological processes of gynecological diseases. For example, changing the immune microenvironment affects the receptivity of the endometrium, thereby leading to abnormal reproductive outcomes, such as embryo implantation failure and recurrent spontaneous abortion. However, the concrete functions and mechanisms of the endometrial microbiome have not been studied thoroughly. This review elaborates the research progress on the mechanisms by which the endometrial microbiome affects endometrial receptivity from the perspective of endometrial immune microenvironment regulation. Considering the lack of a unified evaluation method for the endometrial microbiome, as well as the lack of an optimal treatment protocol against recurrent spontaneous abortion, we also discussed the application of combining antibiotics with probiotics/prebiotics as precautionary measures.

Abstract
OBJECTIVES Morphological study is a common approach in the field of anterior disc displacement (ADD) pathology; however, analysis based on three-dimensional reconstructive imaging has not been investigated. This study investigated the association between ADD and the status of the mandibular condyle and articular fossa. METHODS Thirty-four patients were divided into three groups: normal articular disc position (NADP), anterior disc displacement with reduction (ADDwR), and anterior disc displacement without reduction (ADDwoR). Multiple grouped comparisons of three different disc statuses were performed by Kruskal-Wallis H test and variance analysis respectively. Receiver-operating characteristic curve was plotted to assess the diagnostic efficacy of the morphological parameters. Multivariate logistic regression analysis was used to investigate the interfering factors of ADD. RESULTS The condylar volume (CV) and condylar superficial area (CSA) in the NADP, ADDwR, and ADDwoR groups exhibited obvious changes (P < 0.05). Both CV and superior joint space (SJS) presented a good diagnostic accuracy for NADP-ADDwoR [area under the curve (AUC)CV = 0.813; AUCSJS = 0.855)], and ADDwR-ADDwoR (AUCCV = 0.858; AUCSJS = 0.801). CSA presented a good diagnostic accuracy for ADDwR-ADDwoR (AUC = 0.813). A multivariate logistic ordinal regression model showed that the CV [odds ratio (OR) = 1.011; regression coefficient (RC) = 0.011, P = 0.018], SJS (OR, 8.817; RC = 2.177; P < 0.001), and medial joint space (MJS) (OR, 1.492; RC = 0.400; P = 0.047) had a significantly impact on the groups. CONCLUSION CV, CSA, SJS, and MJS were significantly associated with the different disc status, and the condyle in ADD exhibited 3-dimensionally altered dimensions. They could be considered as promising biometric markers to assess the ADD.

Abstract
BACKGROUND Head and neck cancer (HNC) is a very popular cancer, with many primary sites and pathological types, at the top of the list of tumors. Chemokines are a class of small molecular basic proteins, whose N-terminal cysteine residues can be divided into four subunits by location and number, which significantly enhances the expression level in all kinds of cancers. However, in HNC, especially in head and neck squamous cell carcinoma, the chemokine CXCL8/9/10/11/13 has not been clearly explored for its diagnosis and prognosis. METHODS The ONCOMINE database was used to analyze the expression of chemokine family in various cancers. After CXCL8/9/10/11/13 was screened out, the expression of CXCL 8/9/11/13 in patients with HNC/normal people were analyzed by UALCAN database. The expression and pathological stages of CXCL 8/9/10/13 in HNC tissues were analyzed by the GEPIA database, and the relationship between its mRNA expression and the overall survival (OS) time of patients with HNC was analyzed by Kaplan-Meier plotter database. In addition, 171 co-expressed genes significantly related to CXCL8/9/10/11/13 mutation were screened by online tool cBioPortal, and the protein interaction network of these genes was constructed by STRING database. Finally, the potential functions of CXCL8/9/10/11/13 and its 171 co-expressed genes were explored by the enrichment and analysis function of David database. RESULTS Transcriptional expression of chemokine 8/9/10/11/13 was significantly increased in patients with HNC. Clinical stage of patients with HNC was significantly correlated with overexpression of CXCL9/10/11. In addition, the chemokine CXCL8/9/10/13 was significantly correlated with over-survival of patients with HNC, so it could be distinguished between short-term and long-term survival of patients with HNC. In conclusion, CXCL8/9/10/11/13 closely connected with the expression and prognosis of HNC. CONCLUSION In this study, our results suggest that chemokine CXCL8/9/10/11/13 may play a critical role in the development of HNC, and, according to relevant data, it may affect the survival and prognosis of patients with HNC.

Abstract
Abstract
DNA damage is assumed to accumulate in stem cells over time and their ability to withstand this damage and maintain tissue homeostasis is a key determinant of aging. Nonetheless, relatively few studies have investigated whether DNA damage does indeed accumulate in stem cells and whether this contributes to stem cell aging and functional decline. Here, we found that, compared with young mice, DNA double strand breaks (DSBs) are reduced in subventricular zone (SVZ)-derived neural stem cells (NSCs) of aged mice, which was achieved partly through the adaptive upregulation of Sirt1 expression and non-homologous end joining (NHEJ)-mediated DNA repair. Sirt1 deficiency abolished this effect, leading to stem cell exhaustion, olfactory memory decline, and accelerated aging. The reduced DSBs and the upregulation of Sirt1 expression in SVZ-derived NSCs with age may represent a compensatory mechanism that evolved to protect stem cells from excessive DNA damage, as well as mitigate memory loss and other stresses during aging.

Abstract
Objective To report a novel multi-port containment (NMC) system for laparoscopic power morcellation to prevent tumoral spread and to evaluate its safety, validity, and feasibility. Methods This retrospective study included women who underwent laparoscopic myomectomy (LM) between January 2014 and August 2020 at a single academic institution. The NMC system was used in the study group (n = 193); the control group underwent unprotected LM (n = 1753). Results After 1:1 propensity score matching, no significant differences in the baseline characteristics were observed between 193 matched pairs. Bag damages were detected in two cases in the study group before morcellation, and the NMC systems were replaced. There were no significant differences between the two groups in terms of the complications, total operative time, estimated blood loss, or postoperative hospitalization duration. In the study group, all operations were completed and no system rupture or leakage was observed. The median follow-up times were 21 and 54 months in the study and control groups, respectively. There was no peritoneal tissue spread in the study group. However, three (3/5, 0.6%) and six (6/1,753, 0.3%) patients in the control group experienced malignant and benign peritoneal tissue spread, respectively. Conclusion The NMC system for laparoscopic power morcellation is valid, safe, and feasible for preventing a tumor spread.

Abstract
BACKGROUND Beta-blockers have gradually become an attractive option for the treatment of infantile hemangiomas. Topical application is preferred to oral administration because of their potential systemic adverse effects. The aim of this study is to investigate the effect of betaxolol in treating superficial infantile hemangioma. METHODS Seventy-four infants admitted to the First Affiliated Hospital of Xinjiang Medical University from 2018 to 2019 were observed and recorded. Variables such as color, size, tension, and thickness were recorded monthly and evaluated using visual analog scales. Multi-factor analysis of variance with repeated measurements and the non-parametric Kruskal-Wallis H test were used to compare clinical effectiveness across the different groups. RESULTS After 6 months of treatment, 33.78% (25/74) showed excellent results, 55.41% (41/74) had good responses, 8.11% (6/74) had moderate responses, and 2.70% (2/74) had poor responses. Local discomfort and systemic complications were not found. There was no significant difference in gender and location of occurrence among groups (p > 0.05), and the effect of topical application of betaxolol was optimum in the children aged 0-3 months (p = 0.002). None of three age groups had statistically significant difference in heart rate and blood pressure after accepting treatment (1 month, p = 0.618; 4 months, p = 0.138; 6 months, p = 0.757). CONCLUSIONS Our study showed that topical administration of betaxolol was effective and well tolerated for superficial infantile hemangiomas, particularly in the early proliferative stage. However, its safety and efficacy need further research.

Abstract
Ataxia telangiectasia mutated (ATM) plays an essential role in DNA damage response and the maintenance of genomic stability. However, the role of ATM in regulating the function of adult neural stem cells (NSCs) remains unclear. Here we report that ATM deficiency led to accumulated DNA damage and decreased DNA damage repair capacity in neural progenitor cells. Moreover, we observed ATM ablation lead to the short-term increase of proliferation of neural progenitor cells, resulting in the depletion of the NSC pool over time, and this loss of NSC quiescence resulted in accelerated cell senescence. We further apply RNA sequencing to unravel that ATM knockout significantly affected Notch signaling pathway, furthermore, notch activation inhibit the abnormal increased proliferation of ATM-/- NSCs. Taken together, these findings indicate that ATM can serve as a key regulator for the normal function of adult NSCs by maintaining their stemness and preventing cellular senescence primarily through Notch signaling pathway.

Abstract
Sepsis is a life-threatening multiple organ dysfunction disease with high mortality and has become leading causes of death affecting intensive care unit (ICU) patients. Both long non-coding RNA (lncRNA) and microRNA (miRNA) are involved in the pathophysiological process of sepsis and can regulate the inflammatory response, both of which could be used as important diagnostic indicators and therapeutic targets of sepsis. The interaction among lncRNA, miRNA and mRNA plays an important role in sepsis and multiple organ dysfunction. This paper reviewed the regulatory relationship of lncRNA, miRNA and mRNA, as well as the regulatory role of lncRNA-miRNA-mRNA axis in inflammatory immune response and multiple organ dysfunction syndrome in sepsis, to provide new targets and strategies for the treatment of sepsis and organ dysfunction.

Abstract
Objective: Osteoarthritis (OA) is a common degenerative joint disease, and animal models have proven pivotal in investigating this disease. This study aimed to develop a primate model of OA that may be more relevant to research studies on OA in humans. Method: Twelve female rhesus macaques were randomly divided into three groups. Four animals were untreated (Control group); four were subjected to the modified Hulth method, involving cutting of the anterior and posterior cruciate ligaments, and transecting the meniscus (Hulth group); and four were subjected to the modified Hulth method combined with cartilage defect (MHCD group). Each primate was subjected to motor ability tests, and underwent arthroscopic, radiographic, morphological, and pathological observation of the knee joints at various times for up to 180 days. Results: Motor ability on Day 180 was significantly lower in the MHCD group than in the Control (p<0.01) and Hulth (p<0.05) groups. Radiographic and morphological examination showed that the severity of knee joint deformity and articular cartilage injury were greater in the MHCD group than in the other groups. Pathological examination showed that cartilage thickness was significantly lower in the MHCD group than in the other groups at the same time points. The Mankin score on Day 180 was markedly higher in the MHCD group than in the Hulth (p<0.05) and Control (p<0.001) groups. Conclusion: The MHCD model of OA closely resembles the pathophysiological processes of spontaneous knee OA in humans. The time required to develop knee OA is shorter using the MHCD model than using the Hulth method.

Abstract
Background: Low-dose methylenetetrahydrofolate (LD-MTX) has been widely used for the treatment of the ectopic pregnancy (EP) for many decades, and related severe adverse toxic effects are rare. Current studies have shown that the polymorphisms of methylenetetrahydrofolate reductase (MTHFR) gene can decrease the MTX clearance, leading to the metabolite accumulation. However, there is a lack of literature report on an MTHFR gene polymorphism associated with adverse toxic effects resulting from the use of LD-MTX in an EP. Case Presentation: We report a rare case of a 38-year-old female who developed persistent fever, grade IV myelosuppression, skin lesions, mucositis, and liver injury after single dose of LDMTX to treat EP. The personalized genetic testing showed that MTHFR TT (677C>T) and MTHFR AA (1298A>C) were detected. Gradually, the symptoms improved after calcium leucovorin (CF) rescue, continuous renal replacement therapy (CRRT), promoting blood system regeneration, and multiple supportive treatments. Conclusion: This is the first report on the serious adverse toxic effects of LD-MTX on an EP patient with MTHFR mutations. We aim to alert obstetricians and gynecologists to this rare condition. The unexpected life-threatening toxicity with LD-MTX should be highly considered and recognized early. In particular, some easily overlooked gastrointestinal, skin, and mucosal symptoms occur earlier than severe myelosuppression. When toxic effects are suspected, detecting the polymorphisms of an MTHFR gene and monitoring MTX concentration in blood could assist us to formulate individualized and active treatments.

Abstract
Purpose The purpose of our study is to explore the antecedents and consequences of team flexibility in an organizational change context. In this regard, we considered team flexibility as an important theoretical mechanism under which the insiders would adapt to organizational change. Participants and Methods A sample of 602 individual data that was nested in 108 teams and 43 organizations was used in this study, collecting from 43 enterprises located in mainland China through questionnaires. We adopted HLM 6.08 to testify all the hypothesized relationships and used the Monte Carlo method to create the confidence intervals for all the indirect effects. Results The empirical results show that 1) balance dimension of ambidexterity and change leadership have a significant positive effect on team flexibility; 2) balance dimension of ambidexterity only has marginal significant effects on employee change-specific adaptive behavior, change-specific proactive behavior, and change fairness. And change leadership has significant positive effects on the three outcomes; 3) team flexibility has a positive influence on the three outcomes. 4) Team flexibility plays a significant mediating role in the links between the balance dimension of ambidexterity and the three outcomes. In addition, team flexibility only has a significant indirect effect on the relationship between change leadership and change-specific adaptive behavior and proactive behavior. Conclusion The current study reveals how team flexibility is established and how such flexibility is associated with employee-level change-specific behavior and perception under an organizational change context. The study indicates that team flexibility is contingent on two factors across two levels: change leadership at team level and balanced ambidexterity at organizational level, which also contributes to individual outcomes of organizational change.

Abstract
Mesenchymal stem cell derived (MSC) exosomes are extracellular vesicles with a diameter of about 50-200 nm. Exosomes contain a large number of biologically active substances including mRNAs, miRNAs, cytokines, chemokines, proteins, lipids, etc. MSC exosomes exert biological effects through paracrine and endocrine pathways in vivo. Uncontrolled inflammation and multiple organ dysfunction are the key roles in the progression of sepsis, moreover, heart, lungs, kidneys and brain are the general target organs to be damaged. MSC exosomes regulate the expression of cytokines, the production of inflammatory cell, the levels of inflammatory response and the recovery of damaged tissues or organ function. Therefore, studying the application of MSC exosomes is significant for the clinical treatment of sepsis. This article reviews the systemic inflammation regulation by MSC exosomes and its protective function on targeted organs such as heart, lungs, kidneys, brain, liver, etc. to provide evidences for the treatment of sepsis.

Abstract
Mesenchymal stem cells (MSCs) are thought to have great potential in the therapy of acute liver injury. It is possible that these cells may be regulated by the stromal cell-derived factor-1 (SDF-1)/CXC chemokine receptor-4 (CXCR4) signaling axis, which has been shown to promote stem cells migration in the inflammation-associated diseases. However, the effects of SDF-1/CXCR4 axis on the MSCs-transplantation-based treatment for acute liver injury and the underlying mechanisms are largely unknown. In this study, we sought to determine whether SDF-1/CXCR4 would augment the therapeutic effect of bone marrow mesenchymal stem cells (BMSCs) by promoting their migration, which may result from activating the phosphoinositide 3-kinase (PI3K)/Akt signaling pathway, in a rat acute liver injury model induced by lipopolysaccharide (LPS). We found that BMSCs transplantation markedly attenuated liver injury and improved the survival of LPS-treated rats. Of interest, overexpression of CXCR4 in BMSCs could substantially promote their migration both in vitro and in vivo, and result in even better therapeutic effects. This might be attributed to the activation of PI3K/Akt signaling pathway in BMSCs that is downstream of CXCR4, as demonstrated by the use of the CXCR4 antagonist AMD3100 and PI3K pathway inhibitor LY294002 assays in vitro and in vivo. Together, our results unraveled a novel molecular mechanism for the therapeutic effect of BMSCs for the treatment of acute liver injury, which may shed a new light on the clinical application of BMSCs for acute liver failure.

Abstract
Background: Leukaemia stem cells (LSCs) are responsible for the initiation, maintenance, and recurrence of acute myeloid leukaemia (AML), an aggressive haematological malignancy associated with drug resistance and relapse. Identifying therapeutic LSC targets is critical to curing AML. Methods Bioinformatics databases were used to identify therapeutic LSC targets. The conditional knockout mice were used to analyse the role of HCK in leukaemogenesis or normal haematopoiesis. Colony-forming assays, cell counting, and flow cytometry were used to detect the viability and function of leukaemia cells. RT-PCR, western blotting, and RNA sequencing were used to detect mRNA and protein expression. Result HCK is expressed at higher levels in LSCs than in haematopoietic stem cells (HSCs), and high HCK levels are correlated with reduced survival time in AML patients. Knockdown of HCK leads to cell cycle arrest, which results in a dramatic decrease in the proliferation and colony formation in human AML cell lines. Moreover, HCK is required for leukemogenesis and leukaemia maintenance in vivo and in vitro. HCK is necessary for the self-renewal of LSCs during serial transplantation and limiting dilution assay. The phenotypes resulting from HCK deficiency can be rescued by CDK6 overexpression in the human cell line. RNA sequencing and gene expression have demonstrated that HCK may sustain cell cycle entry and maintain the self-renewal ability of LSCs through activating the ERK1/2-c-Myc-CDK6 signalling axis. In contrast, HCK deletion does not affect normal haematopoiesis or haematopoietic reconstruction in mice. Conclusions HCK maintains the self-renewal of leukaemia stem cells via CDK6 in AML and may be an ideal therapeutic target for eradicating LSCs without influencing normal haematopoiesis.

Abstract
The objective of this study was to evaluate the real-world application, efficacy, and safety data of olaparib for maintenance therapy and active treatment in patients with ovarian cancer in China. Patients with ovarian cancer from 17 institutions in China treated with olaparib as maintenance or active therapy from January 2018 to March 2020 were included in this study. The medical records were reviewed, and follow-up information was collected for analysis of the patients' clinicopathologic characteristics as well as the effectiveness and safety of olaparib. A total of 251 patients receiving olaparib were included, with 84 as maintenance therapy after first-line chemotherapy (FL-M), 97 as maintenance therapy after platinum-sensitive recurrence (PSR-M), and 70 as active treatment (AT). The probability of progression-free survival (PFS) at 12 months was 87.6% in the FL-M group and 63.8% in the PSR-M group. According to the multivariate analysis, complete response (CR) to chemotherapy for the PSR-M patients was the only factor affecting the PFS (HR = 0.414, P = 0.014), and platinum sensitivity was the only factor affecting PFS improvement in the AT group (HR = 0.317, P = 0.009). In the AT group, the objective response rate was 37.1%, the CR rate was 7.1%, and 30% of the patients had stable disease. Eight (3.2%) patients discontinued olaparib due to toxicity. Anemia was the most common adverse event. In conclusion, olaparib is effective and well tolerated in the real-world setting of ovarian cancer treatment. Platinum sensitivity is positively correlated to the effectiveness of olaparib in both maintenance and active treatment.

Abstract
B cell receptor associated protein 31 (BAP31) is a member of the B cell receptor that functions as a transporter for numerous types of newly formed proteins from the endoplasmic reticulum to the Golgi apparatus. Previous studies found that that BAP31 serves an important role in the pathogenesis of malignancy but its specific effect on ovarian cancer is not clear. The present study aimed to investigate whether BAP31 affects ovarian cancer and its underlying mechanism. In the present study, ovarian cancer tissue, human ovarian normal epithelial cell line IOSE80 and five ovarian cancer cell lines (A2780, Hey-T30, COC1, SKOV3 and OVCAR3) underwent reverse transcription-quantitative PCR, western blotting, Cell Counting Kit-8, Transwell and co-immunoprecipitation (Co-IP) assay and transcriptome sequencing. Previous studies showed that compared with healthy tissues, the expression level of BAP31 protein was found to be significantly higher in various types of cancer tissues, implying that BAP31 may serve an important role in the pathogenesis of cancer. The present study found that BAP31 expression was upregulated in five ovarian cancer cell lines and ovarian cancer tissue, such that BAP31 knockdown [performed using two short hairpin (sh)RNA plasmids] decreased proliferation, invasion and migration. In addition, BAP31 knockdown was found to downregulate the expression of N-cadherin and upregulate the expression of E-cadherin on transcriptional level by controlling the nuclear aggregation of TWIST1, a transcriptional regulator of N-cadherin and E-cadherin. There was no interaction between BAP31 and E-cadherin or N-cadherin using Co-IP detection, while BAP31, E-cadherin and N-cadherin interacted with TWIST1 protein. E-cadherin and N-cadherin expression levels recovered when TWIST1 was overexpressed in the shBCAP31 cells. These results suggest that BAP31 can regulate the migration and invasion of ovarian cancer cells through the epithelial-mesenchymal transition pathway at the transcriptional level, which may be beneficial for the identification of potentially novel targets for ovarian cancer therapy.

Abstract
Piwil2 reprograms HPV-infected reserve cells in the cervix into tumor-initiated cells (TICs) and upregulates Wnt3a expression sequentially, which leads to cervical intraepithelial neoplasia (CIN) and ultimately squamous cell carcinoma (SCC). However, little is known regarding Wnt signaling in the maintenance of TIC stemness during the progression of cervical lesions. We herein investigated the expression of canonical Wnt3a signaling and related genes by microarray data set analysis and immunohistochemical (IHC) staining of samples obtained by biopsy of normal cervix, low- and high-grade CIN, and invasive SCC tissue. Array data analyzed by GEO2R showed higher expression levels of Wnt signaling and their target genes, significant upregulation of stemness-associated markers, and notably downregulated cell differentiation markers in CIN and SCC tissues compared with those in the normal cervix tissue. Further, Gene Set Enrichment Analysis (GSEA) revealed that Wnt pathway-related genes significantly enriched in SCC. IHC staining showed gradually increased immunoreactivity score of Wnt3a and CBP and notable translocation of β-catenin from the membrane to the cytoplasm and nucleus during the lesion progression. The intensity and proportion of P16, Ki67 and CK17 staining also increased with the progression of cervical lesions, whereas minimal to negative Involucrin expression was observed in CIN2/3 and SCC. Therefore, canonical Wnt signaling may contribute to the progression of CIN to SCC and may be a potential therapeutic target.

Abstract
The aim of this paper was to investigate the clinical and magnetic resonance imaging (MRI) features of synovial chondromatosis (SC) of the temporomandibular joint (TMJ). Fourteen patients with SC of the TMJ were included in the study. Clinical and MRI features were analysed and divided into three types based on MRI classification: type I with loose bodies, type II with homogeneous masses, and type III with a mixture of loose bodies and homogeneous masses. All SCs occurred in the superior compartment of the TMJ. There were two patients (14%) categorised as type I, five (36%) as type II and seven (50%) as type III. Four patients (29%) had disc perforation, and nine had bone erosion; among those nine, seven (78%) had type III and two (22%) type II. Histological examination showed inflammation and calcification in the synovial membrane and, and cartilage of the hyaline type in all cases. MRI has advantages in the diagnosis of SC.

Abstract
OBJECTIVE Drug-resistance and metastasis are major reasons for the high mortality of ovarian cancer (OC) patients. Cyclooxygenase-2 (COX-2) plays a critical role in OC development. This study was designed to evaluate the effects of COX-2 on migration and cisplatin (cis-dichloro diammine platinum, CDDP) resistance of OC cells and explore its related mechanisms. METHODS Cell counting kit-8 (CCK-8) assay was used to detect the cytotoxicity effects of celecoxib (CXB) and CDDP on SKOV3 and ES2 cells. The effect of COX-2 on migration was evaluated via the healing test. Western blot and real-time quantitative polymerase chain reaction (qPCR) were used to analyze E-cadherin, vimentin, Snail, and Slug levels. RESULTS COX-2 promoted drug-resistance and cell migration. CXB inhibited these effects. The combination of CDDP and CXB increased tumor cell sensitivity, reduced the amount of CDDP required, and shortened treatment administration time. COX-2 upregulation increased the expression of Snail and Slug, resulting in E-cadherin expression downregulation and vimentin upregulation. CONCLUSIONS COX-2 promotes cancer cell migration and CDDP resistance and may serve as a potential target for curing OC.

Abstract
OBJECTIVE Vitamin D deficiency plays an important role in chronic obstructive pulmonary disease (COPD). However, the effects of vitamin D supplementation on lung function decline in COPD were inconsistently reported and a meta-analysis is thus needed. MATERIALS AND METHODS Eligible cohort and randomized controlled trials (RCTs) were searched from databases including PubMed, Embase, and Web of Science. Pooled standardized mean difference (SMD) with 95% confidence interval (CI) was calculated in a random or fixed effects model. RESULTS Eight studies reaching the inclusion criteria and involving 687 COPD patients were included. Pooled effect size showed vitamin D treatment resulted in no significant improvements in FEV1 (SMD: 0.38, 95% CI: -0.13 to 0.88, p= 0.144), FVC (SMD: 0.55, 95% CI: -0.49 to 1.58, p=0.299), and FEV1/FVC (SMD: 0.00, 95% CI: -0.27-0.27, p=0.995) in COPD patients. Subgroup analysis revealed neither short-term (<6 months) (SMD: 0.10, 95% CI: -0.17 to 0.37, p=0.479) nor long-term (≥6 months) (SMD: 0.52, 95% CI: -0.23 to 1.27, p=0.172) vitamin D exposure could significantly benefit lung function decline in COPD. CONCLUSIONS This meta-analysis shows neither short-term nor long-term additional supplementation of vitamin D can benefit the lung function decline in COPD. Moreover, large scale RCTs focusing on COPD smokers with low level of vitamin D should be considered.
