Objective:To evaluate the preventive effects of transcutaneous electrical acupoint stimulation (TEAS) on chronic pain after lumbar spine surgery.Methods:This was a secondary analysis conducted on the studies assessing the effect of TEAS on gastrointestinal function in patients undergoing lumbar spinal surgery. Fifty lumbar spinal stenosis patients of either sex, aged 50-75 yr, with a body mass index of 18.5-28.0 kg/m 2, of American Society of Anesthesiologists Physical Status cassification Ⅰ or Ⅱ, with expected operation time≥3 h, undergoing lumbar spinal surgery under general anesthesia, were enrolled and assigned into 2 groups ( n=25 each) using a random number table method: control group (C group) and TEAS group. In group C, stimulating electrodes were placed at the non-acupoint parts of the limbs, but no electrical stimulation was applied. In group TEAS, the bilateral Neiguan (PC6), Hegu (L14), Zusanli (ST36), Shangjuxu (ST37) and Xiajuxu (ST39) were stimulated with disperse-dense waves at a frequency of 2/100 Hz. The intensity of stimulation was the maximum current that patients could tolerate. The intervention was performed once a day for 30 min per session at 30 min prior to anesthesia induction and on postoperative days 1-7. Telephone follow-ups were conducted at 3, 6 and 12 months after surgery to record the occurrence of postoperative moderate-to-severe lower back pain and leg pain (Numerical Rating Scale score ≥4), and the Oswestry Disability Index (ODI) value and four-item neuropathic pain questionnaire scores. The pain-related medical visits and usage of nonsteroidal anti-inflammatory drugs were also recorded after surgery. Results:Three patients in each group were lost to follow-up. Compared with group C, the incidence of chronic low back pain was significantly decreased at 6-12 months after surgery, the ODI value and four-item neuropathic pain questionnaire scores were decreased at 12 months after surgery ( P<0.05), ODI value difference reached the minimal clinically important difference, the proportion of patients requiring medical visits due to postoperative pain and usage rate of nonsteroidal anti-inflammatory drugs were decreased at 6-12 months after surgery ( P<0.05), and no significant change in the incidence of chronic moderate-to-severe leg pain was found at each time period after surgery in group TEAS( P>0.05). Conclusions:TEAS can prevent the occurrence of chronic lower back pain and improve functional impairment in patients undergoing lumbar spine surgery.

This study explores whether the current external quality assessment (EQA) level and acceptable bias for basic semen analysis in China are clinically useful. We collected data of semen EQA from Andrology laboratories in the Hunan Province (China) in 2022 and searched for data in the published literature from January 2000 to December 2023 in China. On the basis of these data, we analyzed the coefficients of variation and acceptable biases of different quality control materials for basic semen analysis through robust statistics. We compared these findings with quality specifications based on biological variation from optimal, desirable, and minimum levels of bias to seek a unified and more suitable semen EQA bias evaluation standard for China's national conditions. Different sources of semen quality control material exhibited considerable variation in acceptable biases among laboratories, ranging from 8.2% to 56.9%. A total of 50.0% of the laboratories met the minimum quality specifications for progressive motility (PR), whereas 100.0% and 75.0% of laboratories met only the minimum quality specifications for sperm concentration and total motility (nonprogressive [NP] + PR), respectively. The Z value for sperm concentration and PR+NP was equivalent to the desirable performance specification, whereas the Z value for PR was equivalent only to the minimum performance specification. This study highlights the feasibility of operating external quality assessment schemes for basic semen analysis using quality specifications based on biological variation. These specifications should be unified among external quality control (EQC) centers based on biological variation.

Schizophrenia (SZ) stands as a severe psychiatric disorder. This study applied diffusion tensor imaging (DTI) data in conjunction with graph neural networks to distinguish SZ patients from normal controls (NCs) and showcases the superior performance of a graph neural network integrating combined fractional anisotropy and fiber number brain network features, achieving an accuracy of 73.79% in distinguishing SZ patients from NCs. Beyond mere discrimination, our study delved deeper into the advantages of utilizing white matter brain network features for identifying SZ patients through interpretable model analysis and gene expression analysis. These analyses uncovered intricate interrelationships between brain imaging markers and genetic biomarkers, providing novel insights into the neuropathological basis of SZ. In summary, our findings underscore the potential of graph neural networks applied to multimodal DTI data for enhancing SZ detection through an integrated analysis of neuroimaging and genetic features.

OBJECTIVE: Glucocorticoid-induced osteoporosis (GIOP) is a common complication of prolonged glucocorticoid therapy. Chlorogenic acid (CGA), a polyphenol with antioxidant properties that is extracted from traditional Chinese medicines such as Eucommiae Cortex, has potential anti-osteoporotic activity. This study aimed to investigate the possible effects of CGA on GIOP in mice and murine long bone osteocyte Y4 (MLO-Y4) cells and explore the underlying molecular mechanisms. METHODS: The protective effects of CGA were initially evaluated in the GIOP mouse model induced by dexamethasone (Dex). The micro-computed tomography, hematoxylin-eosin staining, silver nitrate staining, and serum detection were used to assess the efficacy of CGA for improving bone formation in vivo. Then, network pharmacology analysis was used to predict the potential targets and molecular mechanisms underlying the therapeutic efficacy of CGA against GIOP. After that, 2',7'-dichlorofluorescein diacetate staining, flow cytometry, real-time quantitative reverse transcription polymerase chain reaction, and Western blotting were used to verify the mechanisms of CGA against GIOP in vitro. RESULTS: Animal experiments showed that CGA treatment effectively attenuated Dex-induced decreases in bone mass and strength and improved disrupted osteocyte morphology in mice. The protein-protein interaction analysis highlighted erb-b2 receptor tyrosine kinase (ERBB2), which is also known as human epidermal growth factor receptor 2 (HER2), caspase-3, kinase insert domain receptor, matrix metallopeptidase 9, matrix metallopeptidase 2, proto-oncogene tyrosine-protein kinase Src, and epidermal growth factor receptor as core targets. The Kyoto Encyclopedia of Genes and Genomes analysis revealed several significantly enriched pathways (P < 0.05), including the ERBB, phosphoinositide 3 kinase-AKT serine/threonine kinase 1 (AKT), and mechanistic target of rapamycin kinase (mTOR) pathways. Cellular experiments verified that CGA enhanced bone formation and promoted autophagy while inhibiting apoptosis in MLO-Y4 cells exposed to Dex, which was associated with the upregulated expression of HER2 and activation of the HER2/AKT/mTOR signaling pathway. CONCLUSION CGA exerted anti-osteoporotic effects against GIOP, partially through targeting osteocytes and modulating the HER2/AKT/mTOR signaling pathway.

OBJECTIVE: To explore and quantify the association of hot night exposure during the sperm development period (0-90 lag days) with semen quality. METHODS: A total of 6,640 male sperm donors from 6 human sperm banks in China during 2014-2020 were recruited in this multicenter study. Two indices (i.e., hot night excess [HNE] and hot night duration [HND]) were used to estimate the heat intensity and duration during nighttime. Linear mixed models were used to examine the association between hot nights and semen quality parameters. RESULTS: The exposure-response relationship revealed that HNE and HND during 0-90 days before semen collection had a significantly inverse association with sperm motility. Specifically, a 1 °C increase in HNE was associated with decreased sperm progressive motility of 0.0090 (95% confidence interval [ CI]: -0.0147, -0.0033) and decreased total motility of 0.0094 (95% CI: -0.0160, -0.0029). HND was significantly associated with reduced sperm progressive motility and total motility of 0.0021 (95% CI: -0.0040, -0.0003) and 0.0023 (95% CI: -0.0043, -0.0002), respectively. Consistent results were observed at different temperature thresholds on hot nights. CONCLUSION Our findings highlight the need to mitigate nocturnal heat exposure during spermatogenesis to maintain optimal semen quality.

OBJECTIVE: Emerging evidence suggests that exposure to ultrafine particulate matter (UPM, aerodynamic diameter < 0.1 µm) is associated with adverse cardiovascular events. Previous studies have found that Shenlian (SL) extract possesses anti-inflammatory and antiapoptotic properties and has a promising protective effect at all stages of the atherosclerotic disease process. In this study, we aimed to investigated whether SL improves UPM-aggravated myocardial ischemic injury by inhibiting inflammation and cell apoptosis. METHODS: We established a mouse model of MI+UPM. Echocardiographic measurement, measurement of myocardialinfarct size, biochemical analysis, enzyme-linked immunosorbent assay (ELISA), histopathological analysis, Transferase dUTP Nick End Labeling (TUNEL), Western blotting (WB), Polymerase Chain Reaction (PCR) and so on were used to explore the anti-inflammatory and anti-apoptotic effects of SL in vivo and in vitro. RESULTS: SL treatment can attenuate UPM-induced cardiac dysfunction by improving left ventricular ejection fraction, fractional shortening, and decreasing cardiac infarction area. SL significantly reduced the levels of myocardial enzymes and attenuated UPM-induced morphological alterations. Moreover, SL significantly reduced expression levels of the inflammatory cytokines IL-6, TNF-α, and MCP-1. UPM further increased the infiltration of macrophages in myocardial tissue, whereas SL intervention reversed this phenomenon. UPM also triggered myocardial apoptosis, which was markedly attenuated by SL treatment. The results of in vitro experiments revealed that SL prevented cell damage caused by exposure to UPM combined with hypoxia by reducing the expression of the inflammatory factor NF-κB and inhibiting apoptosis in H9c2 cells. CONCLUSION Overall, both in vivo and in vitro experiments demonstrated that SL attenuated UPM-aggravated myocardial ischemic injury by inhibiting inflammation and cell apoptosis. The mechanisms were related to the downregulation of macrophages infiltrating heart tissues.

Objective To assess stromal fibrosis in epidermal growth factor receptor(EGFR)mutant lung adenocarcinoma and its association with resistance to targeted therapy and patient prognosis.Methods Medical records of 207 patients diagnosed with EGFR-mutant advanced lung adenocarcinoma who received treatment at a hospital between January 2021 and December 2022 were reviewed.A total of 86 patients were ultimately included based on their prognosis and survival duration.These patients were categorized into a resistance group(32 cases)and a non-resistance group(54 cases),depending on whether they developed resistance to targeted therapy within one year.Additionally,patients were classified into mild,moderate,and severe fibrosis groups according to the extent of fibrosis observed.Clinical and pathological characteristics,as well as fibrosis levels,were compared between the two groups.Factors influencing the development of resistance to targeted therapy in patients with EGFR-mutant lung adenocarcinoma were analyzed,and the survival outcomes of patients with varying degrees of fibrosis were evaluated during follow-up.Results In the resistance group,the prevalence of EGFR exon 20 insertion mutations,elevated CA125 levels,and the presence of moderate-to-severe fibrosis were significantly higher compared to the non-resistance group(P<0.05).Multivariate logistic regression analysis revealed that EGFR exon 20 inser-tion mutation(OR=3.691,95%CI:1.043～13.057),elevated CA125 levels(OR=4.104,95%CI:1.160～14.517),and moderate-to-severe fibrosis(OR=3.959,95%CI:1.410～11.115)were independent risk factors associated with resistance to targeted therapy among patients with EGFR-mutant lung adenocarcinoma(P<0.05).The Cox proportional hazards model demonstrated a C-index of 0.72(95%CI:0.65～0.79),with area under the curve(AUC)values for 1-year and 2-year survival predictions of 0.781 and 0.734,respectively.EGFR exon 20 insertion mutation(HR=3.691),moderate-to-severe fibrosis(HR=3.959),and elevated CA125 levels(HR=4.104)were identified as independent prognostic factors for overall survival in these patients following targeted therapy.The median progression-free survival(PFS)for patients with mild,moderate,and severe fibrosis was 10.5 months,7.2 months,and 3.9 months,respectively,while the median overall survival(OS)was 21.4 months,16.1 months,and 11.5 months,respectively.Statistically significant differences in both PFS and OS were observed across the three fibrosis severity groups.(P<0.05).Conclusion The extent of stromal fibrosis in EGFR-mutant lung adenocarcinoma influences resistance to targeted therapy,and the progression of fibrosis is correlated with an unfavorable prognosis.

Microbial-derived metabolites are important mediators of host-microbial interactions. In recent years, the role of intestinal microbial metabolites in colorectal cancer has attracted considerable attention. These metabolites, which can be derived from bacterial metabolism of dietary substrates, modification of host molecules such as bile acids, or directly from bacteria, strongly influence the progression of colitis-associated cancer (CAC) by regulating inflammation and immune response. Here, we review how microbiome metabolites short-chain fatty acids (SCFAs), secondary bile acids, polyamines, microbial tryptophan metabolites, and polyphenols are involved in the tumorigenesis and development of CAC through inflammation and immunity. Given the heated debate on the metabolites of microbiota in maintaining gut homeostasis, serving as tumor molecular markers, and affecting the efficacy of immune checkpoint inhibitors in recent years, strategies for the prevention and treatment of CAC by targeting intestinal microbial metabolites are also discussed in this review.

Objective: To analyze the disease burden of chronic obstructive pulmonary disease (COPD) and changes in its risk factors among residents in Zhejiang Province from 1990 to 2021, so as to identify key priorities for COPD prevention and control. Methods: Data on COPD mortality and disability-adjusted life years (DALY) for residents in Zhejiang Province from 1990 to 2021 were collected from the Global Burden of Disease (GBD) 2021 database. Standardized mortality and standardized DALY rate were calculated using the GBD 2021 world population standard structure. Premature mortality was computed via the life table method. The average annual percent change (AAPC) was applied to analyze trends in COPD mortality, DALY rate, and premature mortality. Changes in deaths of COPD risk factors were evaluated using population attributable fraction (PAF). Results: From 1990 to 2021, the standardized COPD mortality in Zhejiang Province decreased from 272.40/100 000 to 70.56/100 000 (AAPC=-4.395%), and the standardized DALY rate declined from 4 167.37/100 000 to 1 071.89/100 000 (AAPC=-4.396%). Similar downward trends were observed in both males (AAPC=-3.933%, -4.173%) and females (AAPC=-4.785%, -4.480%), all P<0.05. Crude mortality and DALY rates increased with age, and the crude mortality and DALY rates of various age groups in Zhejiang Province showed decreasing trends from 1990 to 2021 (all P<0.05). The premature mortality declined from 4.37% to 0.60% from 1990 to 2021 (AAPC=- 6.206%), with consistent trends across males and females (AAPC=- 6.144%, - 6.379%, all P<0.05). From 1990 to 2021, particulate matter pollution showed the largest reduction in PAF (- 56.76%), while ambient ozone pollution had the largest increase (103.07%) in Zhejiang Province. By 2021, smoking became the leading risk factor for deaths of COPD (PAF=43.32%). Conclusions The standardized mortality, standardized DALY rate, and premature mortality for COPD show consistent declining trends in Zhejiang Province from 1990 to 2021. However, risk factors such as smoking and ambient ozone pollution require intensified focus to further reduce disease burden of COPD.
