The aim of this study was to determine the impact of nerve preservation confirmed by intraoperative electrical stimulation (IES) on subjective symptoms of urinary and sexual function in uterine cervical cancer patients who underwent radical hysterectomies. This study included 85 patients who underwent type C radical hysterectomy with IES. Pelvic splanchnic nerve preservation with IES after hysterectomy (nerve-stimulation positive group) was confirmed in 61 women and 24 women did not have nerve preservation (negative group). Urinary function was assessed with the Overactive Bladder Symptom Score (OABSS), International Prostate Symptom Score (IPSS), and International Consultation on Incontinence Questionnaire-Short Form (ICIQ-SF) questionnaires. Sexual function was surveyed using the Female Sexual Function Index (FSFI). Longitudinal changes in those scores according to response to nerve-stimulation were evaluated using a generalized estimating equation. IPSS quality of life (QOL) scores were significantly better in the nerve-stimulation positive group compared with the scores in the negative group until 12 months after surgery, whereas OABSS, IPSS total, IPSS voiding, and ICIQ-SF scores evaluating urinary symptoms were not significantly different between the two groups. FSFI scores were better in the nerve-stimulation positive group 36 months after surgery compared with the scores in the negative group. In this study, we assessed self-reported urinary and sexual symptoms after nerve-sparing radical hysterectomy (NSRH) with IES in the long term. We demonstrated that nerve-sparing significantly reduced distress associated with QOL until 1 year, improved urinary storage symptoms at 2 years, and sexual symptoms 3 years after surgery.

Non-islet cell tumor hypoglycemia (NICTH) is one of the paraneoplastic syndromes manifesting severe hypoglycemia caused by aberrant production of high-molecular-weight insulin-like growth factor 2 (big-IGF2). Two surgical cases of extremely large thoracic solitary fibrous tumors (SFT) with unusual history of NICTH are presented. One case manifested severe hypoglycemia after four years of the first complete surgical resection of the tumor with potential malignant transformation, and the other case showed severe hypoglycemia after ten years of the first detection of the tumor. Meticulous laboratory testing, including serum endocrinological tests and western immunoblotting before and after surgery was performed, and both cases were diagnosed as NICTH. Both patients underwent open thoracic surgery. The patients showed normal glucose and hormone levels immediately after the resection of responsible tumors with elevated blood insulin concentration. SFTs are generally considered benign; however, life-threatening hypoglycemia can happen regardless of treatment. Careful follow-up of the tumor growth is warranted.

MicroRNAs (miRNAs) are related to the regulation of bone metabolism. Delayed fracture healing (DFH) is a common complication after fracture surgery. The study attempted to examine the role of miR-98-5p and bone morphogenetic protein (BMP)-2 with the onset of DFH. A total of 140 patients with femoral neck fracture were recruited, including 80 cases with normal fracture healing (NFH) and 60 cases with DFH. MC3T3-E1 cells were induced cell differentiation for cell function experiments. Real-time quantitative polymerase chain reaction (RT-qPCR) was carried out to test mRNA levels. Cell proliferation and apoptosis were determined via CCK-8 and flow cytometry assay. Luciferase reporter assay was done to verify the targeted regulatory relationship of miR-98-5p with BMP-2. In comparison with NFH cases, DFH patients owned high levels of serum miR-98-5p and low concentration of BMP-2, and the levels of the two indexes are significantly negatively correlated. Both miR-98-5p and BMP-2 had the ability to predict DFH, while their combined diagnostic value is the highest. BMP-2 was demonstrated to be the target gene of miR-98-5p. Overexpression of BMP-2 reversed the role of miR-98-5p in MC3T3-E1 cell proliferation, apoptosis and differentiation. Increased miR-98-5p and decreased BMP-2 serve as potential biomarkers for the diagnosis of DFH. MiR-98-5p overexpression inhibits osteoblast proliferation and differentiation via targeting BMP-2.

This study aimed to investigate the effects of a Roy adaptation model (RAM)-based cognitive stimulation therapy (CST) intervention on elderly patients diagnosed with primary non-small cell lung cancer (NSCLC) undergoing curative resection. A total of 280 patients diagnosed with primary NSCLC were randomized into RAM-based CST group and control group. Outcomes were assessed at three intervals: pre-surgery, discharge, and one-month post-discharge. Cognitive function was evaluated using Mini-Cognitive test. Postoperative delirium prevalence was determined within 48 hours post-surgery using Nursing Delirium Screening Scale. The Hospital Anxiety and Depression Scale evaluated anxiety and depression symptoms, while Quality of Life (QoL) was assessed via Short Form-36 (SF36) Health Survey. The RAM-based CST group demonstrated significantly higher Mini-Cog test scores than the control group upon discharge and post-intervention. Patients with RAM-based CST exhibited a decrease in postoperative delirium compared to the control group. The RAM-based CST intervention yielded an improvement in anxiety and depression at discharge and 1-month post-discharge compared to preoperative levels. Additionally, the RAM-based CST group exhibited substantial enhancements in SF36 subcategory scores at 1-month post-discharge compared to pre-surgery. At post-intervention, the RAM-based CST group demonstrated significantly higher scores than the control group across various health-related domains, including role limitations due to emotional problems, mental health, general health perception, bodily pain, and role limitations due to physical problems. The RAM-based CST intervention in elderly NSCLC patients undergoing curative resection yielded significant enhancements in cognitive function, reduced delirium incidence, improved emotional well-being, and better QoL postoperatively.

Recent advancements in computed tomography (CT) scanning have improved the detection rates of peripheral pulmonary nodules, including those with ground-glass opacities (GGOs). This study focuses on part-solid pure ground-glass nodules (GGNs) and aims to identify imaging predictors that can reliably differentiate primary lung cancer from nodules with other diagnoses among part-solid GGNs on high-resolution CT (HRCT). A retrospective study was conducted on 609 patients who underwent surgical treatment or observation for lung nodules. Radiological findings from pre-operative HRCT scans were reviewed and several CT imaging features of part-solid GGNs were examined for their positive predictive value to identify primary lung cancer. The proportions of the nodules with a final diagnosis of primary lung cancer were significantly higher in part-solid GGNs (91.9%) compared with solid nodules (70.3%) or pure GGNs (66.7%). Among CT imaging features of part-solid GGNs that were evaluated, consolidation-to-tumor ratio (CTR) < 0.5 (98.1%), pleural indentation (96.4%), and clear tumor border (96.7%) had high positive predictive value to identify primary lung cancer. When two imaging features were combined, the combination of CTR < 0.5 and a clear tumor border was identified to have 100% positive predictive values with a sensitivity of 40.8%. Thus we conclude that part-solid GGNs with a CTR < 0.5 accompanied by a clear tumor border evaluated by HRCT are very likely to be primary lung cancers with an acceptable sensitivity. Preoperative diagnostic procedures to obtain a pathological diagnosis may potentially be omitted in patients harboring such part-solid GGNs.

Thickening of the ligamentum flavum is the main factor in the development of lumbar spinal canal stenosis (LSCS). Although previous studies have reported factors related to ligamentum flavum thickening, its etiology has not been clarified. Furthermore, it is often difficult to set proper controls to investigate the pathologies of thickening due to differences in patient characteristics, such as age, sex, obesity, and comorbidities. This study aimed to elucidate the pathologies of ligamentum flavum thickening by comparing the dural and dorsal sides of the thickened ligamentum flavum in patients with LSCS. Ligamentum flavum samples were collected from 19 patients with LSCS. The samples were divided into the dural and dorsal sides. The dural side was used as a control to assess the pathologies occurring on the dorsal side. Elastic Masson staining was used to assess the elastic fibres. Gene expression levels were comprehensively assessed using quantitative reverse transcription polymerase chain reaction and DNA microarray analyses. Gene ontology analysis was used to identify biological processes associated with differentially expressed genes. The elastic fibres were significantly decreased on the dorsal side of the thickened ligamentum flavum. Genes related to fibrosis, inflammation, tissue repair, remodeling, and chondrometaplasia, such as COL1A2, COL3A1, COL5A1, TGFB1, VEGFA, TNFA, MMP2, COL10A1, and ADAMTS4, were highly expressed on the dorsal side of the thickened ligamentum flavum. The biological processes occurring on the dorsal side of the thickened ligamentum flavum were extracellular matrix organization, cell adhesion, extracellular matrix disassembly, and proteolysis.These are considered important pathologies of ligamentum flavum thickening.

Indium lung is an occupational lung disease caused by exposure to indium-tin-oxide (ITO) dust. Compared to other occupational lung diseases, indium lung has a shorter latency period and the respiratory status continues to worsen even after exposure to the work environment improves. Paraseptal emphysema which affects mainly the subpleural area is seen on chest images obtained via computed tomography (CT), regardless of the smoking history. However, the pathogenesis of emphysema in indium lung is still unclear. Therefore, we re-evaluated the pathology of three previously reported cases of indium lung. Paraseptal emphysema was observed in both smokers and nonsmokers. Obstructive respiratory impairment worsened over time in the cases with paraseptal emphysema. Many alveolar walls were destroyed independent of the presence or absence of emphysetamous changes or fibrosis. Moreover, bronchiolitis was found to be less common in indium lung than in asbestosis (the most common occupational lung disease) or common cases of chronic obstructive pulmonary disease caused by smoking. It has been shown that ITO causes protease anti-protease imbalance, oxidant-antioxidant imbalance, and continuous, abnormal inflammation (the three major causes of emphysema). In addition, nano-sized ITO is less likely to be trapped in the upper airways and may easily reach the subpleural alveoli. Furthermore, ITO may continue to cause sustained tissue injury at the alveolar level potentially resulting in emphysema. Further studies are needed to elucidate the detailed pathogenesis of indium lung by comparing it with other occupational lung diseases.

Depression disorder has become a major mental disease and has attracted special attention globally. Identifying specific biomarkers for the diagnosis and severity of depression disorder would benefit its clinical management. This study focused on the significance of lncRNA SNHG14 in depression disorder and investigated its effect on depression-like behaviors, aiming to explore a potential biomarker for depression disorder occurrence and development. This study included 147 patients with depression disorder and 98 healthy individuals. The serum SNHG14 in all participants was analyzed by PCR, and its diagnostic value was evaluated by receiver operatorating characteristic curve (ROC) analysis. The depression-like behaviors were induced via chronic social defeat stress (CSDS) and evaluated by sucrose preference, forced swimming, and open field tests. SNHG14 was significantly upregulated in depression disorder patients relative to healthy individuals, which discriminated depression disorder patients with a relatively high efficiency. Depression disorder patients with severe conditions showed higher serum SNHG14 levels, and a significantly positive correlation of SNHG14 with PHQ9 score was demonstrated. In CSDS mice, increasing SNHG14 and decreasing miR-200a-3p were observed. Silencing SNHG14 and overexpressing miR-200a-3p could alleviate reduced sucrose preference, increased swimming immobility time, decreased standing times, and decreased traveling distance induced by CSDS. The knockdown of SNHG14 promoted the expression of miR-200a-3p, and silencing miR-200a-3p could reverse the protective effect of SNHG14 silencing on depression-like behaviors. SNHG14 served as a biomarker for the occurrence and severity of depression disorder. Silencing SNHG14could alleviate depression-like behaviors via modulating miR-200a-3p.

Early childhood caries (ECC) is common in children. Little is known about the genetic association of the methionine synthesis reductase (MTRR) gene rs1801394 and methionine synthetase (MTR) gene rs1805087 polymorphisms with ECC, which was examined in the Chinese Han population. Genotyping was performed using the buccal mucosa from 150 normal and 150 ECC children. For genotype and allele distribution comparison, Chi-square test and multiple logistic regression analysis were performed. The odd ratio (OR) and 95% confidence interval (CI) were calculated. MTR gene rs1805087 AG genotype distribution in the ECC group was clearly different from the control group (P = 0.029), and the ECC risk in cases with AG genotype was 0.525 times lower than those carrying AA genotype (95% CI = 0.292-0.942). Logistic regression analysis after adjustment for other clinical indicators determined that the MTR gene rs1805087 AG genotype was still strongly associated with susceptibility to ECC (OR = 0.499, 95% CI = 0.273-0.913, P = 0.024). Significant association was also seen for sugary food intakes (OR = 1.965, 95% CI = 1.162-3.321, P = 0.012), tooth brushing (OR = 0.569, 95% CI = 0.356-0.924, P = 0.023) and sex (OR = 0.562, 95% CI = 0.349-0.907, P = 0.018) with ECC risk. No notable genetic association was found between MTRR gene rs1801394 polymorphism and ECC risk. MTR gene rs1805087 polymorphism may aggrandize the susceptibility to ECC, and AA genotype appeared to be a dangerous element for the development of ECC.

Septic acute kidney injury (AKI) is a common complication in critically ill patients with high morbidity and mortality. This study intends to clarify the clinical value and molecular mechanism of microR-380-3p in septic AKI by recruiting patients with septic AKI and establishing septic AKI cell models. Patients with septic AKI were included and human kidney-2 (HK-2) cells were induced by lipopolysaccharide (LPS) to construct the AKI cell model of sepsis. The expression of microR-380-3p was detected by quantitative real-time RT-PCR (qRT-PCR). The expression of Bax, cleaved caspase 3, Bcl-2, p65, and p-p65 was detected by Western blot. The contents of inflammation and oxidation were determined by commercial kits. Bioinformatics predicted the binding target of microR-380-3p and a dual luciferase reporting system was used to verify the regulatory relationship between microR-380-3p and RAP1B. The concentration of microR-380-3p was elevated in patients with septic AKI and appeared to be a biomarker for these patients. Silenced microR-380-3p reversed the damage of LPS on HK-2 cells via promoting viability, inhibiting apoptosis, inflammation, and oxidation. RAP1B was a target of microR-380-3p and microR-380-3p exerted targeted inhibition of RAP1B expression level. Down-regulation of RAP1B reversed the influence of silenced microR-380-3p on HK-2 cells. MicroR-380-3p/RAP1B participated in activating the NF-κB pathway. MicroR-380-3p down-regulated RAP1B to exacerbate septic AKI, providing a potential therapeutic biomarker for septic AKI.
