Objective To investigate the expression of YWHAQ protein in gastric adenocarcinoma tissues and its correlation with clinical pathological features and prognosis. Methods A total of 127 patients with gastric cancer who underwent radical surgery were enrolled. Clinical data and postoperative cancer tissue samples were collected from the patients. Immunohistochemistry was used to detect the protein expression of YWHAQ in gastric adenocarcinoma tissues. The relationship between YWHAQ expression and clinical pathological features and prognosis was analyzed. Bioinformatics prediction was performed to identify potential pathways regulated by YWHAQ in gastric adenocarcinoma. A protein-protein interaction network for YWHAQ was constructed using the STRING database. Results YWHAQ gene expression was significantly higher in gastric adenocarcinoma tissues than in normal tissues (P<0.05). The expression level of the YWHAQ protein was significantly correlated with age, tumor invasion depth, lymph node metastasis, and tumor stage (P<0.05). Kaplan-Meier survival analysis showed that patients with high YWHAQ expression had significantly poorer long-term survival than those with low expression (P<0.0001). Cox regression analysis revealed that high YWHAQ expression and distant metastasis were independent risk factors for gastric cancer (HR>1, P<0.05). Enrichment analysis indicated that YWHAQ positively regulated processes such as cell cycle, angiogenesis, and DNA damage repair. Conclusion YWHAQ is highly expressed in gastric adenocarcinoma tissues and may be associated with the occurrence, invasion, and metastasis of gastric adenocarcinoma. High YWHAQ expression and distant metastasis are independent risk factors for the prognosis of gastric adenocarcinoma patients.

BackgroundMigraine is a common chronic neurological disease， and patent foramen ovale （PFO） has been closely associated with migraine. Current research primarily focuses on the pathological mechanism and the therapeutic effects of interventional closure， with limited attention paid to the impact of PFO on sleep quality in migraine patients. ObjectiveTo compare the difference in sleep quality between PFO-positive and PFO-negative migraine patients， and to analyzes influencing factors of sleep quality in PFO-positive migraine patients， so as to provide references for clinical interventions to improve sleep quality in PFO-positive migraine patients. MethodsA total of 673 migraine patients who met the diagnostic criteria of migraine in the International Classification of Headache Disorders， third edition （ICHD-3）， and all patients underwent contrast-enhanced transcranial Doppler （c-TCD） and transthoracic echocardiographic right heart contrast echocardiography （cTTE） in the Third Hospital of Mianyang from January 2020 to October 2024. Basic demographic data were collected using a self-designed questionnaire， headache severity was assessed with the Visual Analogue Scale （VAS）， and sleep quality was invaluated using the Pittsburgh Sleep Quality Index （PSQI）. PFO patients was diagnosed through c-TCD combined with c-TTE. Binary logistic regression analysis was employed to examine the influencing factors of sleep quality in PFO-positive migraine patients. ResultsA total of 673 （100.00%） migraine patients were enrolled， including 223 PFO-positive cases （33.14%） and 450 PFO-negative cases（66.86%）. The PFO-positive group showed significantly more severe headache severity （χ²=15.799， P<0.01） and poorer sleep quality （χ²=14.377， P<0.01） compared with PFO-negative group. PFO-positive patients demonstrated significantly higher barrier factor scores of sleep quality， sleep latency， sleep efficiency， sleep disturbance， hypnotic medication use， and daytime dysfunction compared with PFO-negative counterparts （t=3.634， 3.269， 2.785， 3.428， 2.907， 3.637， Bonferroni adjust P<0.05/7=0.007）.By contrast， no significant difference was noted in sleep duration scores between the two groups（t=2.349， Bonferroni adjust P>0.05/7=0.007）.The Binary Logistic regression analysis revealed that age （OR=1.021， 95% CI： 1.001~1.041）， headache severity （OR=6.030， 95% CI： 4.085~8.901）， and PFO grade （OR=1.893，95% CI： 1.288~2.784）were significant influencing factors for sleep quality in migraine patients with PFO. ConclusionMigraine patients with PFO-positive exhibited poorer sleep quality compared wtih PFO-negative patients. Older age， higher headache servity， and more severe PFO grade are identified as risk factors for impaired sleep quality in PFO-positive migraine patients.

OBJECTIVE: To explore the impact factors and the clinical significance of the urination intermittences in benign prostatic hyperplasia (BPH) patients. METHODS: A retrospective study was performed in BPH patients who underwent urodynamic studies in Beijing Jishuitan Hospital form January 2016 to June 2021. The patients were aged 45 to 84 years with a median age of 63 years, and all the patients had no previous history of neurological disease and had no positive findings in neurological examinations. All the patients had free uroflometry followed by urethral catheterization and urodynamic tests. The voiding work of bladder was calculated using the detrusor power curve method, and the voiding power of bladder and the voiding energy consumption were also calculated. The frequency of urination intermittences generated in uroflometry was also recorded and the patients were divided into different groups according to it. The detrusor pressure at maximal flow rate (P_detQ_max), the maximal flow rate (Q_max), the bladder contractile index (BCI), the bladder outlet obstruction index (BOOI), the voiding work, the voiding power, and the voiding energy consumption were compared among the different groups. Multiva-riate analyses associated with presence of urination intermittences were performed using step-wise Logistic regressions. RESULTS: There were 272 patients included in this study, of whom, 179 had no urination intermittence (group A), 46 had urination intermittence for only one time (group B), 22 had urination intermittence for two times (group C), and 25 had urination intermittence for three times and more (group D). The BCI were 113.4±28.2, 101.0±30.2, 83.3±30.2, 81.0±30.5 in groups A, B, C, and D, respectively; The voiding power were (29.2±14.8) mW, (16.4±9.6) mW, (14.5±7.1) mW, (8.5±5.0) mW in groups A, B, C, and D, respectively, and the differences were significant (P < 0.05). The BOOI were 41.6±29.3, 46.4±31.0, 41.4±29.0, 42.7±22.8 in groups A, B, C, and D, respectively; The voiding energy consumption were (5.41±2.21) J/L, (4.83±2.31) J/L, (5.02±2.54) J/L, (4.39±2.03) J/L in groups A, B, C, and D, respectively, and the differences were insignificant (P>0.05). Among the patients, 179 cases were negative in presence of urination intermittences and 93 cases were positive. Step-wise Logistic regression analysis showed that bladder power (OR=0.814, 95%CI: 0.765-0.866, P < 0.001), BCI (OR=1.023, 95%CI: 1.008-1.038, P=0.003), and bladder work (OR=2.232, 95%CI: 1.191-4.184, P=0.012) were independent risk factors for urination intermittences in the BPH patients. CONCLUSION The presence of urination intermittences in the BPH patients was mainly influenced by bladder contractile functions, and was irrelevant to the degree of bladder outlet obstruction. The increase of frequency of urination intermittences seemed to be a sign of the decrease of the bladder contractile functions in the BPH patients.

Objective:To evaluate direct and indirect costs for schizophrenia,major depressive disorder(MDD)and bipolar disorder,and to compare their differences of cost composition,and to explore the drivers of the total costs.Methods:A total of 3 175 inpatients with schizophrenia,MDD,and bipolar disorder were recruited.In-patient's self-report total direct of medical costs outpatient and inpatient,out-of-pocket costs,and direct non-medical costs were regarded as direct costs.Productivity loss and other loss caused by damaging properties were defined as indirect costs.The perspectives of this study included individual and societal levels.Multivariate regression analysis was applied for detecting the factors influencing disease costs.Results:The total cost of schizophrenia was higher than those of MDD and bipolar disorder at individual and societal levels.The indirect costs of three mental disorders were higher than the direct costs,and the indirect cost ratio of bipolar disorder was higher than those of schizophre-nia and MDD.Age,gender,working condition and marital status(P＜0.05)were the important drivers of total costs.Conclusion:The economic burden of the three mental disorders is relatively heavy.Schizophrenia has heaviest disease burden,and the productivity loss due to mental disorders is the driving force of the soaring disease cost

BACKGROUND:Temporomandibular joint osteoarthritis is a common oral disease with a high incidence.However,temporomandibular joint osteoarthritis is not easy to be detected in the early stage,and it is difficult to obtain clinical pathological specimens,so it is difficult to carry out related research.The application of digital 3D printing technology to animal models of Temporomandibular joint osteoarthritis increases the consistency of the animal models,thus promoting the study of temporomandibular joint osteoarthritis. OBJECTIVE:To establish a standardized animal model of temporomandibular joint osteoarthritis using novel digital technology. METHODS:According to the different modeling methods of unilateral anterior crossbite,30 female Sprague-Dawley rats were randomly divided into traditional model group,digital model group,and control group(n=10 per group).Cartilage specimens of the condyles were collected at 4 and 8 weeks after modeling.The apparent morphology was observed by stereoscopic microscope.The pathological morphology was observed by hematoxylin-eosin staining and Safranin O/fast green staining.Changes in the expression of interleukin-1β and tumor necrosis factor-α were observed by ELISA,and changes in the expression of aggrecan,type Ⅱ collagen and matrix metalloproteinase-13 were observed by immunohistochemical staining. RESULTS AND CONCLUSION:Different degrees of degeneration were observed in the digital and traditional model groups.The body mass of rats in both the model groups decreased during the 1st week after intervention and subsequently demonstrated growth trend and were significantly lower than that in the control group.The results of stereoscopic microscope showed that at 4 and 8 weeks after modeling,the deformation and defect degree of the digital model group was significantly higher than that of the traditional model group.At these two time points,the Osteoarthritis Research Society International scores of the digital model group and the traditional model group were higher than those of the control group,and the Osteoarthritis Research Society International score of the digital model group was higher than that of the traditional model group(P＜0.05).Histopathological observation showed that the modified Mankin score and Osteoarthritis Research Society International score of the two model groups were significantly higher than those of the control group of the same age at 4 and 8 weeks after modeling(P＜0.05).Immunohistochemical staining results showed that at two time points,compared with the control group of the same age,the expression of aggrecan and type Ⅱ collagen decreased in the traditional model group and the digital model group,while the expression of matrix metalloproteinase 13 increased(P＜0.05).ELISA results showed that the expression levels of inflammatory factors interleukin-1β and tumor necrosis factor-α in the traditional and digital model groups were higher than those in the control group at 8 weeks,and the expression levels of interleukin-1β and tumor necrosis factor-α in the digital model group were higher than those in the traditional model group(P＜0.05).To conclude,the personalized metal tube designed and produced by 3D printing technology can quickly guide the osteoarthritis-like lesions of the temporomandibular joint without repeated trial and adjustment,which is reproducible and suitable for promotion and application.
