ObjectiveThis paper aims to explore the risk factors for chronic atrophic gastritis （CAG） with turbidity toxin accumulation syndrome and establish a prediction model. MethodsClinical data of 180 patients with CAG who participated in the "clinical study of Xianglian Huazhuo Particles blocking CAG cancer transformation" of Hebei Sheng Zhong Yi Yuan from July 2021 to March 2022 were collected. After confounding factors were controlled by propensity score matching， patients were divided into a training set （namely dev） and a validation set （namely vad） in a seven to three ratio. The risk factors for CAG with turbidity toxin accumulation syndrome in the training set were investigated by using univariate Logistic regression analysis and least absolute shrinkage and selection operator （namely Lasso） regression algorithms. Subsequently， a model， named model 1se， was developed by using the training set data to predict the risk factors for CAG with turbidity toxin accumulation syndrome. The accuracy of the prediction model was assessed by using various methods， including the receiver operating characteristic （ROC） curve， Hosmer-Lemeshow test （H-L）， calibration plot， and decision curve analysis （DCA）. ResultsAge， body mass index （BMI）， family history of cancer， job and life satisfaction， yellow and greasy fur with slippery pulse， and heavy body sensation were independent risk factors of the model. The prediction model showed excellent predictive value for both the training and validation sets. ConclusionThe established prediction model for CAG with turbidity toxin accumulation syndrome has high discrimination and excellent calibration， which could provide an excellent clinical basis for disease diagnosis and individualized treatment of patients.

Background: This study was performed to characterize the incidence, costs, and risk factors associated with renal and cardiovascular adverse outcomes following primary percutaneous coronary intervention (pPCI) in patients with ST-elevation myocardial infarction (STEMI). Methods: Patients with STEMI who underwent pPCI using iso-osmolar contrast were enrolled at 39 centers. The incidence of acute kidney injury (AKI) and major adverse renal and cardiovascular events (MARCE) was analyzed, as well as inpatient costs. Logistic regression analysis was performed to identify risk factors. Results: Among 2,293 patients, the incidence of AKI and MARCE within 72 hours post-pPCI was 4.14% (n = 95) and 4.40% (n = 101), respectively. AKI and/or MARCE were associated with systolic blood pressure (AKI: odds ratio [OR], 1.009; 95% confidence interval [CI], 1.000–1.018), hypertension (AKI: OR, 1.815; 95% CI, 1.133–2.906; MARCE: OR, 1.760;95% CI, 1.118–2.769), anterior wall infarction (AKI: OR, 1.895; 95% CI, 1.196–3.004; MARCE:OR, 1.939; 95% CI, 1.240–3.032), Killip class (AKI: OR, 1.465; 95% CI, 1.117–1.922; MARCE:OR, 1.467; 95% CI, 1.131–1.903), and serum creatinine (SCr; MARCE: OR, 1.006; 95% CI, 1.000–1.012). Hospitalization costs for patients with STEMI who developed AKI or MARCE were significantly higher than for those without AKI (9,595 ± 5,795 vs. 8,279 ± 3,872 USD, P = 0.003) or without MARCE (9,890 ± 5,616 vs. 8,255 ± 3,859 USD, P < 0.001). Conclusions In patients with STEMI undergoing pPCI with iso-osmolar contrast, the incidence of AKI and MARCE was associated with higher hospitalization costs. Systolic blood pressure, hypertension, anterior wall infarction, Killip class, and SCr were identified as risk factors for these outcomes.

Objective To compare the efficacy and safety of transurethral blue laser vaporization of the prostate, transurethral resection of the prostate (TURP) or plasmakinetic resection of the prostate in the treatment of benign prostatic hyperplasia (BPH). Methods The domestic and foreign clinical studies on transurethral blue laser vaporization of the prostate (observation group), TURP or plasmakinetic resection of the prostate (control group) in the treatment of BPH during Jan. 2015 and Mar. 2025 were retrieved. The data were extracted with Cochrane systematic review method. The operation time, decrease in hemoglobin, bladder irrigation time, catheter indwelling time, total complication rate, retrograde ejaculation rate and urinary incontinence rate of the two groups were compared with RevMan 5.3.0 statistical software. Results A total of 5 Chinese studies involving 491 patients (248 in the observation group and 243 in the control group) were included in the Meta-analysis. Compared with the control group, the observation group had shorter operation time [MD=-20.80, 95%CI:-26.88—-14.72, P＜0.00001], less decrease in hemoglobin [MD=-10.61, 95%CI: -20.21—-1.01, P=0.03], shorter bladder irrigation time [MD=-17.85, 95%CI: -32.62—-3.09, P=0.002], shorter catheter indwelling time [MD=-1.71, 95%CI: -2.81—- 0.62, P=0.002], lower total complication rate [OR=0.11, 95%CI: 0.06—0.21, P＜0.00001], lower retrograde ejaculation rate [OR=0.05, 95%CI: 0.02—0.16, P＜0.00001] and lower urinary incontinence rate [OR=0.24, 95%CI: 0.07—0.79, P=0.02]. There were no significant differences in other complications between the two groups (P＞0.05). The international erectile function score (IIEF-5) of the observation group was significantly higher than that of the control group [MD=1.87, 95%CI:1.16—2.57, P＜0.00001]. There were no significant differences in international prostate symptom score (IPSS), maximum urinary flow rate (Qmax) and post-voiding residual (PVR) between the two groups (P＞0.05). Conclusion All three surgical procedures can effectively improve the lower urinary tract symptoms of BPH patients. Compared with TURP or plasmakinetic resection of the prostate, transurethral blue laser vaporization of the prostate has obvious advantages in terms of perioperative recovery, reduction of total complications, urinary incontinence and retrograde ejaculation rates, and preservation of sexual function.

BackgroundBipolar disorder is a severe mental disorder characterized by alternating episodes of mania and depression. It has a high recurrence rate and a high rate of disability. Elderly patients often suffer from more severe cognitive impairment due to neurodegenerative changes. The clinical intervention for bipolar disorder mainly relies on drug treatment， but drugs have limited effects on improving cognitive function， and some drugs may even aggravate cognitive impairment. Aerobic exercise， as a non-drug intervention method， has shown positive effects in improving cognitive function in patients with mental disorders. However， there are still insufficient studies on elderly patients with bipolar disorder. ObjectiveTo explore the impact of aerobic exercise on the cognitive function of elderly patients with bipolar disorder， so as to provide references for the formulation of strategies to improve the cognitive function of this population. MethodsA randomized controlled trial was conducted. A total of 60 elderly patients who were hospitalized at the Third People's Hospital of Lanzhou from January 2024 to March 2025 and met the diagnostic criteria for bipolar disorder as defined in the International Classification of Diseases，tenth edition （ICD-10） were selected. They were divided into the study group and the control group， with 30 cases in each group， based on the random number table method. Both groups were given quetiapine fumarate tablets and magnesium valproate sustained-release tablets. The study group additionally received aerobic exercise （including slow walking， doing exercises， and running）， three times a week， for 30 minutes each time. At the baseline and at the end of the 3^rd， 6^th， 9^th， and 12^th week of the intervention， the Hamilton Depression Scale -24 item （HAMD-24）， the Young Manic Rating Scale （YMRS）， the Montreal Cognitive Assessment （MoCA）， and Wechsler Adult Intelligence Scale Revised in China （WMS-RC） were used for assessment. ResultsThe time effect of the HAMD-24 score was statistically significant （Wald χ²=124.564， P<0.01）. The time effect of the YMRS score was also statistically significant （Wald χ²=145.608， P<0.01）， and the interaction effect between time and group was statistically significant （Wald χ²=14.968， P<0.05）. At the 3^rd， 9^th， and 12^th week of the intervention， the YMRS score of the study group was lower than that of the control group in the same period， and the differences were statistically significant （P<0.05）. The time effect and group effect of the MoCA score were both statistically significant （F=99.347， 16.623， P<0.01）. The time effect， group effect， and interaction effect between time and group of the WMS-RC memory quotient were all statistically significant （F=64.678， 10.197， 12.472， P<0.01）. At the 6^th， 9^th， and 12^th weeks of the intervention， the MoCA score and WMS-RC memory quotient of the study group were higher than those of the control group， and the differences were statistically significant （P<0.05）. ConclusionAerobic exercise may help improve the manic symptoms and cognitive functions （especially memory ability） of elderly patients with bipolar disorder. ［Funded by Science and Technology Project of Gansu Province （number， 24JRRA775）； Science and Technology Project of Lanzhou City（number， 2022-5-155）］

BackgroundNon-suicidal self-injury （NSSI） behavior is highly prevalent during adolescence. Previous studies have mainly focused on the relationship between NSSI behavior and emotional regulation， pain perception， reward mechanisms， and impulsivity. However， the cognitive mechanisms underlying the occurrence and maintenance of NSSI behavior have not been sufficiently explored. Adolescence is a critical period for the development of cognitive control. However， it remains unclear whether adolescents with depressive disorder accompanied by NSSI behavior have abnormal cognitive control. ObjectiveTo reveal the potential deficits in cognitive control among adolescents with depressive disorder accompanied by NSSI behavior. MethodsThis study was a case-control study including 166 adolescent patients who visited the Third People's Hospital of Lanzhou from November 2024 to May 2025 and met the diagnostic criteria for depressive disorder in the Diagnostic and Statistical Manual of Mental Disorders， fifth edition （DSM-5）. According to whether they had NSSI behavior or not， patients were divided into the NSSI group （n=86） and the non-NSSI group （n=80）. At the same time， healthy adolescents who passed mental health screenings in five public middle schools in the northwest region were selected as the control group （n=71）. All participants completed the color-word Stroop task， and the accuracy rates and reaction time in congruent and incongruent conditions of each group were recorded， and the interference effect based on accuracy rates and reaction time was calculated. ResultsIn terms of accuracy rate， the main effect of trial type was statistically significant （F=46.900， P<0.01， ηp²=0.160）， and the interaction effect between group and trial type was also statistically significant （F=3.390， P=0.035， ηp²=0.028）. In terms of reaction time， the main effect of trial type was statistically significant （F=72.020， P<0.01， ηp²=0.240）， and the interaction effect between group and trial type was also statistically significant （F=6.400， P=0.002， ηp²=0.050）. Simple effect analysis revealed that under both congruent and incongruent conditions， the reaction time of the NSSI group was longer than those of the non-NSSI group and the control group， and the reaction time of the non-NSSI group was also longer than that of the control group （P<0.01）. There were statistically significant differences in the interference effects among three groups based on reaction time （H=10.231， P=0.006）. The interference effect in the NSSI group was higher than that in the control group （Z=3.012， P_adj=0.008） and the non-NSSI group （Z=2.453， P_adj=0.043）. There was no statistically significant difference in the interference effect among the three groups based on accuracy rate （H=5.666， P=0.059）. ConclusionAdolescents with depressive disorder accompanied by NSSI behavior exhibit cognitive control deficits beyond depressive symptoms， particularly showing impaired conflict suppression ability. ［Funded by Lanzhou Municipal Health Industry Scientific Research Project （number，A2026019）］

OBJECTIVE To systematically evaluate the methodological quality of the postoperative chemotherapy guidelines/ consensuses for ovarian epithelial tumor. METHODS A search was conducted across databases including PubMed， Embase， Web of Science， CBM， VIP， Chinese Medical Journal Data， Wanfang Data， and CNKI， as well as the official websites of GIN， NICE， Medlive， AHRQ， CSCO， ASCO， and NCCN. The search period was from the establishment of the databases/websites to March 10， 2025. The quality of the included guidelines/consensus was evaluated by using the AGREE-Ⅱ tool. RESULTS A total of 16 guidelines/consensuses were included. The domain scores of AGREE-Ⅱ evaluation were as follows： scope and purpose of 85.07%， participants of 47.92%， rigor of development of 57.49%， clarity of presentation of 88.02%， applicability of 8.20%， and independence of 53.39%. Among them， 14 were recommended at grade B and 2 were recommended at grade C. The subgroup analysis by different countries/regions and different types of studies showed that the scores for participants， rigor of development， and independence of the guidelines/consensuses in China were significantly lower than foreign countries （P＜0.05）； the scores for participants and rigor of development of the guidelines were significantly higher than consensuses （P＜0.05）. The guideline/ consensus recommendation results indicated that grade B guidelines/consensus recommend platinum-based combination chemotherapy as the preferred adjuvant chemotherapy regimen for stage Ⅰ high-grade serous carcinoma patients；platinum-based combination chemotherapy±bevacizumab was recommended as the preferred adjuvant chemotherapy regimen for stage Ⅱ-Ⅳ high- grade serous carcinoma patients and for platinum-sensitive recurrent high-grade serous carcinoma patients； non-platinum single- agent chemotherapy±bevacizumab was recommended as the preferred chemotherapy regimen for platinum-resistant recurrent high- grade serous carcinoma patients. CONCLUSIONS The overall quality of postoperative chemotherapy guidelines/consensuses for ovarian epithelial tumor is not high. The methodological quality of guidelines/consensuses in China is still lagging behind that of foreign countries. The recommendations differ from those in foreign countries. It is recommended to improve the aspects of participants， rigor of development， and independence， to recommend treatment plans based on the different stages of ovarian cancer， and develop guidelines/consensuses that align with China’s national conditions.

Sleep deprivation (SD) has emerged as a significant modifiable risk factor for Alzheimer’s disease (AD), with mounting evidence demonstrating its multifaceted role in accelerating AD pathogenesis through diverse molecular, cellular, and systemic mechanisms. SD is refined within the broader spectrum of sleep-wake and circadian disruption, emphasizing that both acute total sleep loss and chronic sleep restriction destabilize the homeostatic and circadian processes governing glymphatic clearance of neurotoxic proteins. During normal sleep, concentrations of interstitial Aβ and tau fall as cerebrospinal fluid oscillations flush extracellular waste; SD abolishes this rhythm, causing overnight rises in soluble Aβ and tau species in rodent hippocampus and human CSF. Orexinergic neurons sustain arousal, and become hyperactive under SD, further delaying sleep onset and amplifying Aβ production. At the molecular level, SD disrupts Aβ homeostasis through multiple converging pathways, including enhanced production via beta-site APP cleaving enzyme 1 (BACE1) upregulation, coupled with impaired clearance mechanisms involving the glymphatic system dysfunction and reduced Aβ-degrading enzymes (neprilysin and insulin-degrading enzyme). Cellular and histological analyses revealed that these proteinopathies are significantly exacerbated by SD-induced neuroinflammatory cascades characterized by microglial overactivation, astrocyte reactivity, and sustained elevation of pro-inflammatory cytokines (IL-1β, TNF-α, IL-6) through NF‑κB signaling and NLRP3 inflammasome activation, creating a self-perpetuating cycle of neurotoxicity. The synaptic and neuronal consequences of chronic SD are particularly profound and potentially irreversible, featuring reduced expression of critical synaptic markers (PSD95, synaptophysin), impaired long-term potentiation (LTP), dendritic spine loss, and diminished neurotrophic support, especially brain-derived neurotrophic factor (BDNF) depletion, which collectively contribute to progressive cognitive decline and memory deficits. Mechanistic investigations identify three core pathways through which SD exerts its neurodegenerative effects: circadian rhythm disruption via BMAL1 suppression, orexin system hyperactivity leading to sustained wakefulness and metabolic stress, and oxidative stress accumulation through mitochondrial dysfunction and reactive oxygen species overproduction. The review critically evaluates promising therapeutic interventions including pharmacological approaches (melatonin, dual orexin receptor antagonists), metabolic strategies (ketogenic diets, and Mediterranean diets rich in omega-3 fatty acids), lifestyle modifications (targeted exercise regimens, cognitive behavioral therapy for insomnia), and emerging technologies (non-invasive photobiomodulation, transcranial magnetic stimulation). Current research limitations include insufficient understanding of dose-response relationships between SD duration/intensity and AD pathology progression, lack of long-term longitudinal clinical data in genetically vulnerable populations (particularly APOE ε4 carriers and those with familial AD mutations), the absence of standardized SD protocols across experimental models that accurately mimic human chronic sleep restriction patterns, and limited investigation of sex differences in SD-induced AD risk. The accumulated evidence underscores the importance of addressing sleep disturbances as part of multimodal AD prevention strategies and highlights the urgent need for clinical trials evaluating sleep-focused interventions in at-risk populations. The review proposes future directions focused on translating mechanistic insights into precision medicine approaches, emphasizing the need for biomarkers to identify SD-vulnerable individuals, chronotherapeutic strategies aligned with circadian biology, and multi-omics integration across sleep, proteostasis and immune profiles may delineate precision-medicine strategies for at-risk populations. By systematically examining these critical connections, this analysis positions sleep quality optimization as a viable strategy for AD prevention and early intervention while providing a comprehensive roadmap for future mechanistic and interventional research in this rapidly evolving field.
