Objective To explore the impact of factors such as economic level,regional differences,and healthcare policies on the medical costs and the clinical treatment behaviors for benign prostatic hyperplasia(BPH)using big data technology.Methods A combination of qualitative and quantitative approaches was employed,including descriptive statistical analysis,central tendency analysis,comparative analysis,and structural analysis to explore regional differences in the treatment of BPH and the underlying causes.Results The mean medical cost per case in the provincial capital city(19 502 yuan)was significantly higher than that in the prefecture-level city(16 526 yuan),with a difference of 2 976 yuan(+18%).Moreover,the cost distribution was more dispersed in the provincial capital([8 370 yuan-26 344 yuan]vs.[9 687 yuan-21 974 yuan]in the prefecture-level city).However,the provincial capital demonstrated better hospitalization efficiency,with a significantly shorter mean length of stay(9.24 days vs 10.21 days,-10.5%).All these differences were statistically significant(P<0.01).Payment methods influenced surgical choices.In the provincial capital,43.99%of patients underwent transurethral resection of the prostate(TURP),with no cases of holmium laser enucleation of the prostate(HOLEP).In contrast,the prefecture-level city reported 22.71%of patients receiving plasmakinetic resection of the prostate(PKRP)and 19.19%undergoing HoLEP.Significant differences were observed in antibiotic utilization patterns.The most commonly used antibiotic in the provincial capital was piperacillin-tazobactam(19.96%),while cefotaxime dominated in the prefecture-level city(21.11%).Notably,ertapenem was frequently used in the provincial capital but rarely in the prefecture-level city,potentially due to cost considerations(P<0.05).Regional preferences were evident in antispasmodic medication;phloroglucinol injection was used in 80%of cases in the prefecture-level city,while anisodamine hydrobromide injection predominated in the provincial capital(P<0.05).For BPH-specific medications,although tamsulosin hydrochloride sustained-release capsules were the primary choice in both regions,the prefecture-level city showed significantly higher usage(80.11%vs 49.17%).Finasteride tablets were more commonly prescribed in the provincial capital(39.03%vs.14.14%,P<0.05).Conclusion Economic levels,healthcare policies,and different hospitals significantly influence clinical decision-making and medical expenses.Hospitals should enhance refined management,while healthcare policy reforms need to advance from multiple perspectives and levels to improve the efficiency and equity of healthcare services.

Objective:This study aims to explore the clinical features and electrophysiological mechanism of depression through event-related potential analysis.Method:Temporal Experience of Pleasure Scale (TEPS) was used to evaluate anticipatory (TEPS-A) and consummatory (TEPS-C) pleasurable experience among 53 participants (20 patients with major depressive disorder (MDD), 14 patients with bipolar depression Ⅱ (BD) and 19 health controls (HC)). Hamilton Depression Scale (HAMD) and Brief Screening Scale for Dementia (BSSD) were used to evaluate patients’ clinical characteristics. All subjects completed gambling task according to the instructions. Meanwhile, continuous electroencephalogram （EEG) was recorded, and feedback negativity in event-related potential was analyzed.Results:Firstly, compared with HC group, the scores of TEPS, TEPs-A and TEPs-C in MDD and BD groups were decreased ( P<0.01). Secondly, the FN amplitude wave decreased significantly in MDD group ((-0.138±2.562) μV), compared with HC ((-2.569±2.598) μV) and BD group ((-2.251±0.954) μV), P<0.05. Thirdly, in contrast to HC ((10.778±6.967) μV) and BD ((10.284±5.540) μV), the MDD group ((6.069±4.353) μV) displayed blunted responses to gain feedback; For the loss feedback, no significant difference was shown among the three groups. Moreover, correlation analysis showed that, for the MDD group, consummatory anhedonia measured by TEPS-C were associated with reduction in response to gain feedback ( r=-0.501 ，P=0.024). Conclusions:Patients with depressive episode FN in MDD was negatively correlated with the score of consummatory pleasurable experience by having a lack of pleasure, which was manifested as the decrease of both anticipatory pleasurable experience and consummatory pleasurable experience. Patients with MDD showed decreased reward sensitivity and decreased FN amplitude, while patients with BD Ⅱ showed no similar trend. The changes in EEG indicated underpinning mechanism of anhedonia in depression.

OBJECTIVE: To explore the better management of the stoma in endoscopic dacryocystorhinostomy. METHOD: To review the 102 chronic dacryocystitis patients (109 eyes), who underwent the endoscopic dacryocystorhinostomy surgery with silver clips used to maintain the stoma. They were given combined therapy after the surgery, and were followed up for a period range from 3-73 months. RESULT: 99/109 eyes (91%) were cured, 5/109 eyes (4.5%) were improved, and the total effective rate reached to 104/109 (95.5%). CONCLUSION The application of silver clip in endoscopy dacryocystorhinostomy surgery and combined therapy after the surgery can effectively prevent the stoma stenosis or atresia.
