Bioinformatics analysis of PANoptosis regulators in the diagnosis and subtyping of steroid-induced osteonecrosis of the femoral head.

In this study, we aimed to investigate the involvement of PANoptosis, a form of regulated cell death, in the development of steroid-induced osteonecrosis of the femoral head (SONFH). The underlying pathogenesis of PANoptosis in SONFH remains unclear. To address this, we employed bioinformatics approaches to analyze the key genes associated with PANoptosis. Our analysis was based on the GSE123568 dataset, allowing us to investigate both the expression profiles of PANoptosis-related genes (PRGs) and the immune profiles in SONFHallowing us to investigate the expression profiles of PRGs as well as the immune profiles in SONFH. We conducted cluster classification based on PRGs and assessed immune cell infiltration. Additionally, we used the weighted gene co-expression network analysis (WGCNA) algorithm to identify cluster-specific hub genes. Furthermore, we developed an optimal machine learning model to identify the key predictive genes responsible for SONFH progression. We also constructed a nomogram model with high predictive accuracy for assessing risk factors in SONFH patients, and validated the model using external data (area under the curve; AUC = 1.000). Furthermore, we identified potential drug targets for SONFH through the Coremine medical database. Using the optimal machine learning model, we found that 2 PRGs, CASP1 and MLKL, were significantly correlated with the key predictive genes and exhibited higher expression levels in SONFH. Our analysis revealed the existence of 2 distinct PANoptosis molecular subtypes (C1 and C2) within SONFH. Importantly, we observed significant variations in the distribution of immune cells across these subtypes, with C2 displaying higher levels of immune cell infiltration. Gene set variation analysis indicated that C2 was closely associated with multiple immune responses. In conclusion, our study sheds light on the intricate relationship between PANoptosis and SONFH. We successfully developed a risk predictive model for SONFH patients and different SONFH subtypes. These findings enhance our understanding of the pathogenesis of SONFH and offer potential insights into therapeutic strategies.

Assessing recent recurrence after hepatectomy for hepatitis B-related hepatocellular carcinoma by a predictive model based on sarcopenia.

BACKGROUND: Sarcopenia may be associated with hepatocellular carcinoma (HCC) following hepatectomy. But traditional single clinical variables are still insufficient to predict recurrence. We still lack effective prediction models for recent recurrence (time to recurrence < 2 years) after hepatectomy for HCC. AIM: To establish an interventable prediction model to estimate recurrence-free survival (RFS) after hepatectomy for HCC based on sarcopenia. METHODS: We retrospectively analyzed 283 hepatitis B-related HCC patients who underwent curative hepatectomy for the first time, and the skeletal muscle index at the third lumbar spine was measured by preoperative computed tomography. 94 of these patients were enrolled for external validation. Cox multivariate analysis was per-formed to identify the risk factors of postoperative recurrence in training cohort. A nomogram model was developed to predict the RFS of HCC patients, and its predictive performance was validated. The predictive efficacy of this model was evaluated using the receiver operating characteristic curve. RESULTS: Multivariate analysis showed that sarcopenia [Hazard ratio(HR) = 1.767, 95%CI: 1.166-2.678, P < 0.05], alpha-fetoprotein ≥ 40 ng/mL (HR = 1.984, 95%CI: 1.307-3.011, P < 0.05), the maximum diameter of tumor > 5 cm (HR = 2.222, 95%CI: 1.285-3.842, P < 0.05), and hepatitis B virus DNA level ≥ 2000 IU/mL (HR = 2.1, 95%CI: 1.407-3.135, P < 0.05) were independent risk factors associated with postoperative recurrence of HCC. Based on the sarcopenia to assess the RFS model of hepatectomy with hepatitis B-related liver cancer disease (SAMD) was established combined with other the above risk factors. The area under the curve of the SAMD model was 0.782 (95%CI: 0.705-0.858) in the training cohort (sensitivity 81%, specificity 63%) and 0.773 (95%CI: 0.707-0.838) in the validation cohort. Besides, a SAMD score ≥ 110 was better to distinguish the high-risk group of postoperative recurrence of HCC. CONCLUSION: Sarcopenia is associated with recent recurrence after hepatectomy for hepatitis B-related HCC. A nutritional status-based prediction model is first established for postoperative recurrence of hepatitis B-related HCC, which is superior to other models and contributes to prognosis prediction.

Effects of priming glycosyltransferase genes cps 2E and cps 4E on the exopolysaccharide biosynthesis by Lactiplantibacillus plantarum YM-4-3 strain.

Microbial exopolysaccharides (EPS) have various physiological functions such as antioxidant, anti-tumor, cholesterol lowering, and immune regulation. However, improving traditional fermentation conditions to increase the production of EPS from Lactiplantibacillus plantarum (L. plantarum) is limited. In this study, we aimed to better improve EPS production and physiological functions of L. plantarum YM-4-3 strain by overexpressing and knocking out the priming glycosyltransferase genes cps 2E and cps 4E for the first time. As a result, the EPS production of the overexpression strain was 30.15 %, 26.84 % and 36.29 % higher than WT, respectively. The EPS production of the knockout strain was significantly lower than that of the WT. At the same time, transcriptome data showed that the gene expression levels of each experimental strain had changed. Kyoto Encyclopedia of Genes and Genomes (KEGG) pathways found that the glycolysis/gluconeogenesis pathway had the highest gene enrichment in the metabolic pathway. The monosaccharide components of the EPS of each experimental strain were different from those of the WT and the EPS of the experimental strain showed stronger activity against oxidation. In conclusion, this study contributes to the efficient production and application of L. plantarum EPS and helps to understand the mechanism of EPS regulation in L. plantarum.

Postmenopausal endometrial non-benign lesion risk classification through a clinical parameter-based machine learning model.

OBJECTIVE: This study aimed to develop and evaluate a machine learning model utilizing non-invasive clinical parameters for the classification of endometrial non-benign lesions, specifically atypical hyperplasia (AH) and endometrioid carcinoma (EC), in postmenopausal women. METHODS: Our study collected clinical parameters from a cohort of 999 patients with postmenopausal endometrial lesions and conducted preprocessing to identify 57 relevant characteristics from these irregular clinical data. To predict the presence of postmenopausal endometrial non-benign lesions, including atypical hyperplasia and endometrial cancer, we employed various models such as eXtreme Gradient Boosting (XGBoost), Random Forest (RF), Logistic Regression (LR), Support Vector Machine (SVM), Back Propagation Neural Network (BPNN), as well as two ensemble models. Additionally, a test set was performed on an independent dataset consisting of 152 patients. The performance evaluation of all models was based on metrics including the area under the receiver operating characteristic curve (AUC), sensitivity, specificity, precision, and F1 score. RESULTS: The RF model demonstrated superior recognition capabilities for patients with non-benign lesions compared to other models. In the test set, it attained a sensitivity of 88.1% and an AUC of 0.93, surpassing all alternative models evaluated in this study. Furthermore, we have integrated this model into our hospital's Clinical Decision Support System (CDSS) and implemented it within the outpatient electronic medical record system to continuously validate and optimize its performance. CONCLUSIONS: We have trained a model and deployed a system with high discriminatory power that may provide a novel approach to identify patients at higher risk of postmenopausal endometrial non-benign lesions who may benefit from more tailored screening and clinical intervention.

Protocol for a prospective longitudinal cohort study on the effects of non-surgical weight loss on pelvic floor dysfunction.

INTRODUCTION: Recent studies have recommended non-surgical weight loss and pelvic floor muscle training as first-line treatment for obese patients with urinary incontinence. However, limited studies are detecting the effect of weight loss on other types of pelvic floor dysfunctions (PFDs), as well as on the quality of life (QoL) and the related influencing factors. METHODS AND ANALYSIS: The "Weight Loss on Pelvic Floor Dysfunction"(WLPFD) observational study is a 6 months prospective, longitudinal real-world cohort study aiming to recruit 200 patients. Participants will be followed up three times during the study: at baseline, and at 2 and 6 months. The methodology involves recruitment and follow-up of participants, data collection through validated questionnaires, and statistical analysis to assess the impact of non-surgical weight loss on PFD and QoL. ETHICS AND DISSEMINATION: This study has been reviewed and given a favourable ethical opinion by the Peking Union Medical College Hospital ethics committee (K4278). All results from the study will be submitted to international journals and international conferences. TRIAL REGISTRATION NUMBER: NCT05987085.

Pelvic floor muscle strength and influencing factors based on vaginal manometry among healthy women at different life stages: A multicentre cross-sectional study.

OBJECTIVE: To assess pelvic floor muscle (PFM) strength and influencing factors among healthy women at different life stages. DESIGN: Multicentre cross-sectional study. SETTING: Fourteen hospitals in China. POPULATION: A total of 5040 healthy women allocated to the following groups (with 1680 women per group): premenopausal nulliparous, premenopausal parous and postmenopausal. METHODS: The PFM strength was evaluated by vaginal manometry. Multivariate logistic regression was used to determine the influencing factors for low PFM strength. MAIN OUTCOME MEASURES: Maximum voluntary contraction pressure (MVCP). RESULTS: The median MVCP values were 36, 35 and 35 cmH2O in premenopausal nulliparous (aged 19-51 years), premenopausal parous (aged 22-61 years), and postmenopausal (aged 40-86 years) women, respectively. In the premenopausal nulliparous group, physical work (odds ratio, OR 2.05) was the risk factor for low PFM strength, which may be related to the chronic increased abdominal pressure caused by physical work. In the premenopausal parous group, the number of vaginal deliveries (OR 1.28) and diabetes (OR 2.70) were risk factors for low PFM strength, whereas sexual intercourse (<2 times per week vs. none, OR 0.55; ≥2 times per week vs. none, OR 0.56) and PFM exercise (OR 0.50) may have protective effects. In the postmenopausal group, the number of vaginal deliveries (OR 1.32) and family history of pelvic organ prolapse (POP) (OR 1.83) were risk factors for low PFM strength. CONCLUSIONS: Physical work, vaginal delivery, diabetes and a family history of POP are all risk factors for low PFM strength, whereas PFM exercises and sexual life can have a protective effect. The importance of these factors varies at different stages of a woman's life.

The difference in extracellular matrix metabolism in women with and without pelvic organ prolapse: A systematic review and meta-analysis.

BACKGROUND: Studies on the changes of extracellular matrix (ECM) in pelvic organ prolapse (POP) are still controversial. OBJECTIVE: To identify the changes in the ECM in POP patients. SEARCH STRATEGY: Comprehensive searching in Embase, PubMed, Web of Science and the Cochrane Library was carried out until 23 February 2023. SELECTION CRITERIA: Studies comparing the protein levels of ECM-related components between women with and without POP. DATA COLLECTION AND ANALYSIS: Quality and risk of bias were assessed using the Agency for Healthcare Research and Quality assessment. Indicators were pooled with random or fixed effect meta-analysis based on heterogeneity and sub-grouped analysed by the biopsy site. MAIN RESULTS: Thirty cross-sectional studies were included, comprising 840 POP cases and 755 controls. Overall results showed that the expression of type III collagen (COLIII) and several matrix metalloproteinases (MMP-1, -2 and -9) were increased, whereas those of type I collagen (COLI), and tissue inhibitor of matrix metalloproteinase-1 (TIMP-1) were decreased in patients with POP. Subgroup analysis showed that the expression of COLIII in the anterior vaginal wall (AVW) and COLIII, MMP-2 and -9 in the uterosacral ligament (USL) were consistent with the overall results. However, the expression of COLI and MMP-1 in the AVW showed no difference and the expression of COLI and MMP-1 in the USL is still controversial based on current studies. CONCLUSIONS: Patients with POP have lower expression of COLI and TIMP-1 and higher expression of COLIII and MMPs compared with non-POP cases, but further studies are required to investigate in specified anatomical sites.

Integration of Multiparameter MRI into Conventional Pretreatment Risk Factors to Predict Positive Surgical Margins After Radical Prostatectomy.

INTRODUCTION/BACKGROUND: Positive surgical margins (PSMs) after radical prostatectomy (RP) can increase the risk of biochemical recurrence in prostate cancer (PCa) patients. However, the prediction of the likelihood of PSMs in patients undergoing similar surgical procedures remains a challenge. We aim to develop a predictive model for PSMs in patients undergoing non-nerve-sparing RP. PATIENTS AND METHODS: In this retrospective study, we analyzed data from PCa patients who underwent minimally invasive non-nerve-sparing RP at our hospital between June 2017 and June 2021. We identified independent risk factors associated with PSMs using clinical and MRI-based parameters in univariate and multivariate logistic regression analyzes. These factors were then used to develop a nomogram for predicting the probability of PSMs. The predictive performance was validated using calibration and receiver operating characteristic curve, area under the curve ,and decision curve analysis. RESULTS: Multivariate analyzes revealed prostate-specific antigen density, tumor size, tumor location at the apex, tumor contact length, extracapsular extension (ECE) level, and apparent diffusion coefficient value as independent risk factors. A nomogram was developed and validated with high accuracy (C-index = 0.78). Furthermore, we found that 44.2% of patients diagnosed with organ-confined disease had ECE after surgery, and 29.1% of patients with Gleason scores ≤7 had higher pathological scores. Interestingly, the tumor burden calculated from PCa biopsy cores was overestimated when compared to postoperative PCa specimens. CONCLUSION: We developed a reliable nomogram for predicting the risk of PSMs in PCa patients undergoing non-nerve-sparing RP. The study highlights the importance of incorporating these parameters in personalized surgical management.

Effect of follicle-stimulating hormone and luteinizing hormone on apoptosis, autophagy, and the release and reception of some steroid hormones in yak granulosa cells through miR-23a/ASK1 axis.

Follicle-stimulating hormone (FSH), luteinizing hormone (LH), miR-23a, apoptosis signal-regulating kinase 1(ASK1)/c-Jun N-terminal kinase (JNK), autophagy and apoptosis play crucial roles in follicular development. However, their role in yak granulosa cells (GCs) remains unknown. Therefore, we examined the effect of miR-23a, ASK1, FSH, and LH on apoptosis, autophagy, and the release and reception of some steroid hormones in these cells. Our results showed that miR-23a overexpression significantly increased the abundance of Beclin1, the LC3II/I ratio, and the number of Ad-mRFP-GFP-LC3-labeled autophagosomes, and decreased p62 abundance. Additionally, Bax abundance and the number of terminal deoxynucleotidyl transferase deoxynucleotide triphosphate nick end labeling-positive cells were reduced, while Bcl2 expression was increased. Overexpression of miR-23a also significantly increased the abundance of estradiol receptor α (ER-α) and ß (ER-ß) and the concentrations of estradiol (E2), progesterone (P4) in yak GCs. Here, treating yak GCs with miR-23a decreased ASK1 expression, which regulates ASK1/JNK-mediated apoptosis, autophagy, E2 and P4 levels, and ER-α/ß abundance. In contrast, treatment of yak GCs with FSH (10 µg/mL) and LH (100 µg/mL) increased miR-23a abundance, regulating the subsequent effect on ASK1/JNK-mediated apoptosis, autophagy, ER-α/ß abundance, and E2 and P4 concentrations. In conclusion, miR-23a enhances autophagy in yak GCs, attenuates apoptosis, and increases ER-α/ß abundance and E2 and P4 concentrations by downregulating ASK1. Additionally, FSH and LH can regulate these effects of miR-23a by altering its expression. These results provide important insights that can inform the development of strategies to reduce abnormal follicular atresia and improve the reproductive rate of yaks.

Effect of Surgically Induced Weight Loss on Pelvic Organ Prolapse: A Meta-analysis.

INTRODUCTION: Bariatric surgery alleviates certain aspects of pelvic floor disorder, but the effect on pelvic organ prolapse (POP) is unclear. To assess the effect of bariatric surgery on POP we conducted the present meta-analysis and firstly performed a subgroup analysis based on the duration of follow-up. METHODS: Four databases including PubMed, The Cochrane Library, Web of Science, and Embase were searched to identify relevant studies published before February 24, 2023. The main outcome was the prevalence and severity of POP symptoms before and after bariatric surgery. Then we assessed the heterogeneity, publication bias and performed subgroup analyses based on follow-up time, study quality and region. RESULTS: Eleven studies with a total of 696 participants met the inclusion criteria. The results showed that the prevalence of POP decreased after bariatric surgery (odds ratio[OR] = 2.29, 95% confidence interval[CI]: 1.05, 5.01; P = 0.04, I2 = 78%), with significant differences observed both at 3-6 months (OR = 2.24, 95% CI: 1.25, 4.01; P = 0.007, I2 = 59%) and 12 months (OR = 4.64, 95% CI: 2.83, 7.58; P < 0.0001, I2 = 0%) of follow-up compared with pre-surgery. Pelvic Organ Prolapse Distress Inventory scores 6-item also decreased after bariatric surgery (mean difference [MD] = 2.11, 95% CI: 0.32, 3.89; P = 0.02, I2 = 55%) with significant differences observed both at 3-6 months (MD = 3.72; 95% CI: [0.10, 7.34], P = 0.04, I2 = 70%) and ≥ 12 months (MD = 3.24; 95% CI: [0.56, 5.91], P = 0.02, I2 = 56%) of follow-up. CONCLUSION: Bariatric surgery alleviated POP symptoms in women with obesity both during short-term (3-6 months) and long-term (≥ 12 months) follow-up.

Impact of female stress urinary incontinence and related treatments on the sexual function of male partners: a systematic review and meta-analysis.

BACKGROUND: No conclusions have been reached on whether female stress urinary incontinence (SUI) and related treatments affect male partners' sexual function. AIM: To assess the effects of female SUI and related treatments on male partners' sexual function. METHODS: A comprehensive search of the PubMed, Embase, Web of Science, Cochrane, and Scopus databases was performed up to September 6, 2022. Studies were included that investigated the effect of female SUI and related treatments on male partners' sexual function. OUTCOME: Male partners' sexual function. RESULTS: Of the 2294 citations identified, 18 studies with 1350 participants were included. Two studies assessed the effect of female SUI without treatment on male partners' sexual function, finding that partners had more erectile dysfunction, more sexual dissatisfaction, and less sexual frequency than partners of women without urinary incontinence. Seven studies directly assessed the effect of female SUI treatments on male partners' sexual function by surveying the male partners. Among these, 4 assessed transobturator suburethral tape (TOT) surgery; 1 assessed TOT and tension-free vaginal tape obturator surgery; and the remaining 2 assessed pulsed magnetic stimulation and laser treatment. Among the 4 TOT studies, 3 used the International Index of Erectile Function (IIEF). TOT surgery significantly improved the total IIEF score (mean difference [MD] = 9.74, P < .00001), along with erectile function (MD = 1.49, P < .00001), orgasmic function (MD = 0.35, P = .001), sexual desire (MD = 2.08, P < .00001), intercourse satisfaction (MD = 2.36, P < .00001), and overall satisfaction (MD = 3.46, P < .00001). However, the improvements in IIEF items may be of unclear clinical significance, as 4 points in the erectile function domain of the IIEF are typically defined as the minimal clinically important difference. In addition, 9 studies indirectly assessed the effect of female SUI surgery on male partners' sexual function by surveying patients with the Pelvic Organ Prolapse/Urinary Incontinence Sexual Questionnaire. The results demonstrated no significant differences in erectile function (MD = 0.08, P = .40) or premature ejaculation (MD = 0.07, P = .54). CLINICAL IMPLICATIONS: The effects of female SUI and related treatments on male partners' sexual function were summarized for the first time, providing a reference for future clinical practice and scientific research. STRENGTHS AND LIMITATIONS: A limited number of studies that used various scales met the standardized eligibility criteria. CONCLUSION: Female SUI may affect male partners' sexual function, and female patients' anti-incontinence surgery does not appear to have a clinically significant improvement on the sexual function of their partners.

Multi-user multi-objective computation offloading for medical image diagnosis.

Computation offloading has effectively solved the problem of terminal devices computing resources limitation in hospitals by shifting the medical image diagnosis task to the edge servers for execution. Appropriate offloading strategies for diagnostic tasks are essential. However, the risk awareness of each user and the multiple expenses associated with processing tasks have been ignored in prior works. In this article, a multi-user multi-objective computation offloading for medical image diagnosis is proposed. First, the prospect theoretic utility function of each user is designed considering the delay, energy consumption, payment, and risk awareness. Second, the computation offloading problem including the above factors is defined as a distributed optimization problem, which with the goal of maximizing the utility of each user. The distributed optimization problem is then transformed into a non-cooperative game among the users. The exact potential game proves that the non-cooperative game has Nash equilibrium points. A low-complexity computation offloading algorithm based on best response dynamics finally is proposed. Detailed numerical experiments demonstrate the impact of different parameters and convergence in the algorithm on the utility function. The result shows that, compare with four benchmarks and four heuristic algorithms, the proposed algorithm in this article ensures a faster convergence speed and achieves only a 1.14% decrease in the utility value as the number of users increases.

[Post-stroke dysphagia treated with four-step acupuncture therapy for opening orifices and benefiting throat combined with neuromuscular electrical stimulation: a randomized controlled trial].

OBJECTIVE: To observe the clinical efficacy on post-stroke dysphagia treated with four-step acupuncture therapy for opening orifices and benefiting throat combined with neuromuscular electrical stimulation. METHODS: Sixty patients with post-stroke dysphagia were randomly divided into an observation group and a control group, with 30 cases in each group. The neuromuscular electrical stimulation was adopted in the control group. Besides the treatment as the control group, in the observation group, the four-step acupuncture therapy for opening orifices and benefiting throat was supplemented. Step 1: the three areas of scalp acupuncture on the affected side were stimulated. Step 2: pricking method was operated on the posterior pharyngeal wall. Step 3: bleeding technique was operated at Jinjin (EX-HN 12) and Yuye (EX-HN 13). Step 4: deep insertion of needle was operated at three-pharynx points. The needles were retained for 30 min at the three areas of scalp acupuncture and the three-pharynx points. The intervention of each group was delivered once daily, 6 times a week, at the interval of 1 day. One course of treatment was 1 week and 4 successive courses were required. The rating of Kubota water swallow test, the score of standardized swallowing assessment (SSA) and the rating of Rosenbek penetration- aspiration scale (PAS) were observed before and after treatment in patients of the two groups. The incidence of clinical complications and clinical efficacy were compared between the two groups. RESULTS: Compared with those before treatment, the rating of Kubota water swallow test, the scores of SSA and the rating of PAS of patients in the two groups were decreased after treatment (P<0.01), and the values of the observation group were lower than those of the control group after treatment (P<0.05). The incidence of clinical complications in the observation group was 13.3% (4/30), lower than 36.7% (11/30) in the control group (P<0.05). The total effective rate in the observation group was 93.3% (28/30), which was better than 70.0% (21/30) in the control group (P<0.05). CONCLUSION: The four-step acupuncture therapy for opening orifices and benefiting throat combined with neuromuscular electrical stimulation can improve the swallowing function of patients with post-stroke dysphagia and reduce the incidence of clinical complications.

[Treatment of degenerative lumbar lateral recess stenosis with full endoscopic lamina fenestration discectomy].

OBJECTIVE: To compare the clinical efficacy of full endoscopic lamina fenestration discectomy (Endo-LOVE) with full endoscopic transforaminal approach discectomy in the treatment of degenerative lumbar lateral recess stenosis. METHODS: A retrospective analysis of 48 patients with degenerative lumbar lateral recess stenosis between March 2018 and March 2019 was performed. There were 32 males and 16 females, aged from 60 to 83 years old with an average of (72.9±6.5) years, course of disease ranged from 5 to 16 years with an average of (8.0±2.8) years. The patients were divided into observation group and control group according to surgical approaches. There were 28 cases in observation group, underwent Endo-LOVE surgery;and 20 cases in control group, underwent full endoscopic foraminal approach discectomy. The operation time, intraoperative blood loss, hospitalization day and complications were observed between two groups. Visual analgue scale (VAS), Japanese Orthopaedic Association(JOA), Oswestry Disability Index(ODI), lateral crypt angle were compared between two groups. And clinical effects were evaluated by modified Macnab standard. RESULTS: There was no significant difference in follow-up and operation time between two groups (P>0.05). Intraoperative blood loss was from 5 to 15 ml with an average of (8.4±3.6) ml in observation group and 5 to 25 ml with an average of (11.5±5.4) ml in control group. The hospitalization day was from 5 to 8 days with an average of (6.0±1.0) days in observation group and 6 to 9 days with an average (7.2±1.1) days in control group. Intraoperative blood loss and hospitalization day were significantly lower in observation group(P<0.05). There were no serious complications in both groups. The VAS, JOA scores, and ODI at 3-month and final follow-up were significantly improved in both groups (P<0.05), and observation group was significantly better than control group (P<0.05). The skeletal lateral crypt angle and soft lateral crypt angle were significantly greater than the preoperative angle at 3 days postoperatively(P<0.05), and observation group was significantly better than control group(P<0.05). At the final follow-up, the modified Macnab criteria was used to assess clinical efficacy, in observation group, 22 patients obtained excellent results, 5 good and 1 fair;while 11 excellent, 4 good and 5 fair in control group;the clinical efficacy of observation group was significantly better than that of control group(P<0.05). CONCLUSION: Both surgical methods are performed under direct vision, with high safety and good clinical efficacy. However, Endo-LOVE enlarged the lateral crypt more fully.

Impaired Cognitive Function in Patients With Autonomous Cortisol Secretion in Adrenal Incidentalomas.

CONTEXT: Glucocorticoids have potent effects on the central nervous system. However, while patients with Cushing syndrome frequently report impairments in cognitive function, studies investigating cognitive function in patients with autonomous cortisol secretion (ACS) in adrenal incidentalomas (AIs) are scarce. OBJECTIVE: The aim of the present study was to evaluate neurocognitive function in patients with ACS. METHODS: We prospectively recruited 63 patients with AI, 36 patients with nonfunctional adrenal adenoma (NFA) (46.5 ± 10.5 years), and 27 patients with ACS (48.6 ± 9.1 years); these patients underwent a battery of validated neuropsychological tests. ACS was diagnosed when serum cortisol levels after a 1-mg dexamethasone suppression test (cortisol1 mg DST) ≥ 50 nmol/L. RESULTS: Patients with ACS had higher frequency of subjective memory complaints (40.7% vs 13.9%, P < 0.05) and higher proportion of mild cognitive impairment (22.2% vs 2.8%, P < 0.05) than patients with NFA. Furthermore, patients with ACS had worse performance on working memory and the visuospatial/constructional domain than patients with NFA (all P < 0.05). Serum cortisol1 mg DST was negatively correlated with working memory and visuospatial/constructional domains (r = -0.307 and -0.306, respectively, all P < 0.05). Performance on working memory and visuospatial/constructional domains gradually deteriorated with increases in serum cortisol1 mg DST (all P values for trend < 0.05). Multivariate linear regression analysis showed that serum cortisol1 mg DST was a significant risk factor for impairment of working memory and visuospatial/constructional domains (B = -0.006 and -0.043, respectively, all P < 0.05). CONCLUSION: This study is the first to report that ACS is accompanied by impaired cognitive function. Consequently, cognitive function assessment should be incorporated into the clinical evaluation of patients with ACS. CLINICAL TRIAL REGISTRATION NUMBER: NCT05357456.

Early chest tube removal following single-direction versus conventional uniportal video-assisted thoracoscopic lobectomy: A retrospective cohort study / 中国胸心血管外科临床杂志

@#Objective    To explore the feasibility of early chest tube removal following single-direction uniportal video-assisted thoracoscopic surgery (S-UVATS) anatomical lobectomy. Methods    The clinical data of consecutive VATS lobectomy by different surgeons in Xuzhou Central Hospital between May 2019 and February 2022 were retrospectively reviewed. Finally, the data of 1 084 patients were selected for analysis, including 538 males and 546 females, with a mean age of 61.0±10.1 years. These patients were divided into a S-UVATS group with 558 patients and a conventional group (C-UVATS) with 526 patients according to the surgical procedures. The perioperative parameters such as operation time, blood loss were recorded. In addition, we assessed the amount of residual pleural effusion and the probability of secondary thoracentesis when taking 300 mL/d and 450 mL/d as the threshold of chest tube removal. Results    Tumor-negative   surgical margin was achieved without mortality in this cohort. As compared with the C-UVATS group, patients in the S-UVATS group demonstrated significantly shorter operation time (P<0.001), less blood loss (P=0.002), lower rate of conversion to multiple-port VATS or thoracotomy (P=0.003), but more stations and numbers of dissected lymph nodes as well as less suture staplers (P<0.001). Moreover, patients in the S-UVATS demonstrated shorter chest tube duration, less total volume of thoracic drainage and shorter postoperative hospital stay, with statistical differences (P<0.001). After excluding patients of chylothorax and prolonged air leaks>7 d, subgroup analysis was performed. First, assuming that 300 mL/d was the threshold for chest tube removal, as compared with the C-UVATS group, patients in the S-UVATS group would report less residual pleural effusion and less necessitating second thoracentesis with residual pleural effusion>500 mL (P<0.05). Second, assuming that 450 mL/d was the threshold for chest tube removal, as compared with the C-UVATS group, the S-UVATS group would also report less residual pleural effusion and less necessitating second thoracentesis with residual pleural effusion>500 mL (P<0.05). Further multivariable logistic regression analysis indicated that S-UVATS was significantly negatively related to drainage volume>1 000 mL (P<0.05); whereas combined lobectomy, longer operation time, more blood loss and air leakage were independent risk factors correlated with drainage volume>1 000 mL following UVATS lobectomy (P<0.05). Conclusion    The short-term efficacy of S-UVATS lobectomy is significantly better than that of the conventional group, indicating shorter operation time and less chest drainage. However, early chest tube removal with a high threshold of thoracic drainage volume probably increases the risk of secondary thoracentesis due to residual pleural effusion.

Status of scoliosis and the related factors among 12yearold school students from Inner Mongolia Autonomous Region in 2021 / 中国学校卫生

Objective@#To understand the current situation and influencing factors of scoliosis in 12-year-old students from Inner Mongolia Autonomous Region, so as to provide scientific basis for accurate prevention and control of abnormal spinal curvature.@*Methods@#From October to November 2021, a total of 18 399 students aged 12 were selected by region and school level by stratified random cluster sampling method, and spinal curvature screening and questionnaire survey of common diseases and health influencing factors among students were carried out. Chi squared test was used for single factor analysis, and binary Logistic regression model was used for multi factor analysis.@*Results@#A total of 397 students (2.2%) were detected with abnormal curvature of the spine, including 368 students (2.0%) with scoliosis. Among them, 205 cases were in the lumbar thoracic segment with a detection rate of 1.1%, 173 cases were in the thoracic segment with a detection rate of 0.9%, and 141 cases were in lumbar thoracic segment with a detection rate of 0.8%. Binary Logistic regression analysis showed that urban area, economic area(moderate), attending tutorial classes before primary school and class seats never changed regularly were positively correlated with the occurrence of scoliosis among 12 year old students ( OR =1.95,1.67,1.76,1.71, P <0.05). Obesity, attending an average of 3 or 4 physical education classes per week, attending physical fitness and beauty classes before primary school were negatively correlated with the occurrence of scoliosis among 12 year old students ( OR =0.69,0.31,0.36,0.71, P <0.05).@*Conclusion@#The prevalence of scoliosis among 12-year-old students in Inner Mongolia Autonomous Region is not optimistic. It should pay attention to the prevention and control of scoliosis in students before the age of 12, actively prevent the occurrence and progress of scoliosis.

Co-occurrence trend of school bullying and depression and its correlation with dietary patterns among middle school students from Inner Mongolia Autonomous Region in 2021 / 中国学校卫生

Objective@#To investigate the correlation between school bullying and depressive symptoms comorbidity and dietary patterns among middle school students in Inner Mongolia Autonomous Region from 2021, so as to provide reference for the prevention of school bullying and depressive symptoms.@*Methods@#In September 2021, stratified random cluster sampling was used to select 87 414 middle school students in 12 leagues in Inner Mongolia Autonomous Region. The Center for Epidemiologic Studies Depression Scale (CES-D) was used to assess depression, and the bullying was determined according to the items related to bullying in the program of Chinese National Surveillance on Students Common Diseases and Risk Factors.@*Results@#In 2021, the detection rate of depressive symptoms among middle school students in Inner Mongolia Autonomous Region was 15.24%, school bullying was 3.02%, and the co-occurrence of school bullying and depression was 1.64%. Binary Logistic regression analysis showed that junior high school students ( OR =1.52) and girls ( OR =1.10) were more likely to suffer from comorbidity of school bullying and depression ( P < 0.05). Eating fried food less than one and more than once a day, smoking and drinking were positively correlated with school bullying and depression comorbidity ( OR =2.15,2.11,2.14,1.70, P <0.05).@*Conclusion@#The combination of bullying and depression among middle school students in Inner Mongolia Autonomous Region is affected by various dietary methods. In terms of diet, reducing the intake of fried food, no smoking, no drinking can effectively reduce the incidence of co-occurrence school bullying and depression.

Prevalence of myopia among children and adolescents in Inner Mongolia Autonomous Region from 2019 to 2021 / 中国学校卫生

Objective@#To analyze the prevalence and trend of myopia among children and adolescents in Inner Mongolia from 2019 to 2021，so as to provide a reference for making scientific and effective prevention and controlling measures of myopia.@*Methods@#By using the stratified random cluster sampling method, 555 093 children and adolescents were selected from 12 professional institutions in league cities of the whole region for remote vision examination and refractive examination. The refraction test was carried out under the condition of non-Ciliary muscle paralysis using a desktop automatic computer optometer. Chi-squared test and multivariate Logistic regression were used to analyze the myopia status of children and adolescents and its influencing factors.@*Results@#From 2019 to 2021, the myopia rate of children and adolescents was 53.30%, 58.65% and 54.82%, respectively, the difference was statistically significant ( χ 2=991.70, P <0.01). The overall female myopia rate(58.82%) was higher than that of male (51.52%), and the differece was statistical significant ( χ 2=3 295.66, P <0.05). The myopia rates of boys and girls by year were 49.44% and 57.30%, 54.76% and 62.60%, 51.23% and 57.62%, respectively, and the differences were statistically significant ( χ 2=1 197.02, 922.31, 1 172.09, P <0.01). The overall myopia rate of urban students (59.42%) was higher than that of suburban counties (53.61%), and the difference was statistically significant ( χ 2=1 565.03, P <0.05). The myopia rates of children and adolescentss in urban and suburban counties were 59.20% and 50.79%, 60.26% and 57.88%, 58.95% and 53.36%, and the differences were statistically significant ( χ 2=1 150.80, 74.10, 529.25, P <0.01). The children and adolescents of learning stages were of statistical significance ( χ 2=92 402.39, P <0.05), and the overall myopia rate of senior school students was the highest, accounting for 83.57%. The difference of overall myopia rates of different age groups was of statistical significance ( χ 2=121 881.67, P <0.05), and the students in age group of 17 ranked the first (83.32%), those in age group of 5 ranked the last(15.52%).@*Conclusion@#From 2019 to 2021, the myopia rate of children and adolescents in the Inner Mongolia Autonomous Region increase first and then decrease, and the myopia rate in 2020 and 2021 is higher than that in 2019. The high incidence and low age of myopia are intensifying. The prevention and controlling of myopia among children and adolescents should be strengthened, so as to reduce the occurance of myopia.
