Arsenic (organoarsenic) compound is one of the oldest drugs used by humans to treat various diseases. From its initial application in treating various skin diseases to the 1970s when arsenic trioxide (ATO) was proven to be able to significantly relieve acute promyelocytic leukemia (APL), arsenic (organoarsenic) compounds gradually occupied an important position in the history of medical development. This article reviews the pharmaceutical research progress of inorganic arsenic compounds and organic arsine compounds, covering anticancer, antiparasitic, antiviral and antibiotic aspects. It further explores the potential for developing new arsenic (organoarsenic) drugs with higher efficacy and lower toxicity, aiming to provide new research directions and ideas for the application of arsenic (organoarsenic) compounds in disease treatment.

Objective:To analyze the color Doppler flow imaging (CDFI) features of familial exudative vitreoretinopathy (FEVR) at different stages.Methods:A retrospective study. A total of 104 patients with 201 eyes from Department of Ophthalmology of Beijing Tongren Hospital who were hospitalized for fundus examination and diagnosed with FEVR from 2018 to 2022 were included. There were 69 male cases with 133 eyes and 35 female cases with 68 eyes. The age was ranged from 2 months to 11 years, with a mean age of 2.9 years. Fundus and CDFI examination were performed in both eyes. Fluorescein fundus angiography was performed in 72 cases (144 eyes). FEVR staging was conducted according to literature standards. The presence of avascular areas in the peripheral retina or abnormal retina neovascularization was stage 1; the presence of retinal neovascularization at the vitreoretinal interface in the avascular area was stage 2; partial retinal detachment without macula involvement was stage 3; partial retinal detachment involving the macula was stage 4; complete retinal detachment was stage 5. The CDFI ultrasound features of FEVR at different stages were analyzed. The CDFI image features of FEVR patients in different stages were observed.Results:Among the 104 patients, 97 (93.3%, 97/104) cases were binocular and 7 (6.7%, 7/104) cases were monocular. In 201 eyes, stages 1 to 5 of FEVR were 49 (24.4%, 49/201), 23 (11.4%, 23/201), 39 (19.4%, 39/201), 71 (35.3%, 71/201), and 19 (9.5%, 19/201) eyes, respectively. CDFI examination showed no abnormality or mild vitreous opacity in 49 eyes vitreous body at stage 1. Vitreous opacities were observed in all 23 eyes in stage 2, and the echo of the temporal ballwall was not smooth. In 39 eyes at stage 3, the anterior globular cluster echo in temporal peripheral eyes was observed in 17 eyes and partial retinal detachment was observed in 13 eyes. In 71 eyes at stage 4, 51 eyes had temporal or infratemporal retinal folds, and 20 eyes had temporal retinal detachment. All the 19 eyes in stage 5 had total retinal detachment, of which 15 eyes had closed "funnel-shaped" retinal detachment. Among the patients with retinal folds, 13 had bilateral folds, and the fellow eyes of the other 25 patients with unilateral folds all had vitreous opacity or clump echo in front of the temporal spherical wall. Blood flow signals could be detected on the retinal folds with Doppler imaging.Conclusions:The CDFI manifestations of FEVR patients at different stages have different characteristics. The possibility of FEVR should be considered when the temporal or infratemporal retinal folds of both eyes are present, as well as the retinal folds of one eye, the contralateral vitreous body opacity, or the anterior temporal peribulbar cluster echoes are present.

Based on whole genome data, the identification and expression pattern analysis of the Atropa belladonna WRKY transcription factor family were conducted to provide a theoretical foundation for studying the biological functions and mechanisms of these transcription factors. In this study, bioinformatics methods were employed to identify members of the A. belladonna WRKY gene family and to predict their physicochemical properties, conserved motifs, promoter cis-acting elements, and chromosomal localization. Additionally, the expression patterns of the A. belladonna WRKY gene family under the regulation of environmental factors such as light quality and temperature were analyzed. The results revealed a total of 28 AbWRKY transcription factors, randomly distributed across 16 chromosomes, encoding 324-707 amino acids. Most AbWRKY proteins were acidic, unstable, and hydrophilic. Based on multiple sequence alignment and phylogenetic analysis, the WRKY gene family members were classified into two subfamilies. Conserved motif and domain analysis indicated that WRKY transcription factors in the same subfamily possessed conserved structural features. Promoter analysis predicted that the A. belladonna WRKY family contained light-responsive elements, hormone-responsive elements, and stress-responsive elements. Collinearity analysis showed that AbWRKY24 plays a crucial role in the expansion of the AbWRKY gene family. Then qRT-PCR results indicated that AbWRKY6, AbWRKY8, AbWRKY14, and AbWRKY24 responded to red light stress, while AbWRKY8, AbWRKY14, and AbWRKY24 responded to yellow light/low-temperature combined stress. AbWRKY6 and AbWRKY8 were significantly expressed in leaves and stems, AbWRKY27 and AbWRKY28 were significantly expressed in fibrous roots, and AbWRKY25 was significantly expressed in flowers. This study is the first to identify and analyze the WRKY gene family in A. belladonna and to examine its expression patterns under light and temperature regulation, laying a foundation for in-depth analysis and functional validation of the molecular mechanisms of A. belladonna WRKY transcription factors in responding to light quality and temperature environmental factors.

Objectives:To examine the functional outcomes of robot-assisted radical prostatectomy (RARP) with preservation of pelvic floor stabilized structure and early elevated retrograde liberation of the neurovascular bundle (PEEL).Methods:This study was a retrospective cohort study. Between June 1, 2022, and March 20, 2023, 27 cases of RARP with PEEL and 153 cases of RARP with preservation of pelvic floor stabilized structure (PPSS) were included in this study. All patients were males, aged (62.5±5.2) years (range: 50 to 73 years). There were 18 cases of ≤T2b stage and 9 cases of T2c stage. After 1∶1 propensity score matching, the postoperative functional outcomes of 27 cases of RARP with PEEL and 27 cases of RARP with PPSS were compared. All surgeries were performed by a single surgeon and included patients were clinically staged as cT1-2N0M0 without preoperative urinary incontinence or erectile dysfunction. In RARP with PEEL, the prostate was cut near the midline at the front when dissecting the neurovascular bundle, dissection was performed between the visceral layer of the pelvic fascia and the prostatic fascia, preserving the parietal layer and the visceral layer of the pelvic fascia, and the neurovascular bundle was retrogradely released from the apex. The cumulative probability curve was plotted using the Kaplan-Meier method and the Log-rank test was used to compare the differences in functional outcomes between the two groups. Univariate and multivariate analysis with the Cox proportional hazards model was used to compare postoperative urinary continence and sexual function.Results:The recovery time of continence and potency was significantly longer in the PPSS group than in the PEEL group (all P<0.05). The continence rate of the PEEL group was significantly higher than that of the PPSS group (92.59% vs. 68.10%, P=0.026) at 3 months after surgery. The potency rate of the PEEL group was also significantly higher than that of the PPSS group (40.70% vs. 15.10%, P=0.037) at 3 months after surgery. In the univariate analysis, compared to the PPSS technique, the PEEL technique was associated with a shorter recovery time of continence ( HR=1.94, 95% CI: 1.08 to 3.48, P=0.027) and a shorter recovery time of potency ( HR=2.06, 95% CI: 1.03 to 4.13, P=0.042). In the multivariate analysis, the PEEL technique was an independent prognosis factor for postoperative recovery of continence ( HR=2.05, 95% CI: 1.01 to 4.17, P=0.047) and potency ( HR=3.57, 95% CI: 1.43 to 8.92, P=0.007). All the cases of the PPSS group and the PEEL group were performed successfully with negative surgical margins. Conclusion:Compared with PPSS, PEEL may be more conducive to the recovery of urinary continence and sexual function after RARP.

【Objective】 To investigate the possibility of using voiding diary (VD) to predict desmopressin diacetate arginine vasopressin (DDAVP) and enuresis alarm (EA) in the treatment of primary monosymptomatic nocturnal enuresis (PMNE). 【Methods】 A total of 100 children (aged 6 to 14 years) with PMNE treated during Jan.2018 and Oct.2022 were involved. Bladder type was classified with two-week VD. Pseudo-randomization was performed using the Danish REDCap system to group patients into the randomized group and VD group. All patients were treated for 8 weeks. 【Results】 A total of 82 cases met the inclusive criteria. The effective rate was 82.50% (33/40) and 59.52% (25/42) in the VD and randomized groups, respectively, with significant difference (χ²=5.224, P=0.022). In the randomized group, if VD was not considered, the effective rate in the DDAVP and EA subgroups was 81.82% (18/22) and 25.00% (5/20), respectively, with significant difference (χ²=13.625, P=0.000). 【Conclusion】 VD can predict the therapeutic effects of PMNE. It is necessary to record VD for two weeks before selecting appropriate treatment methods. For patients who choose treatment without reference to VD, DDAVP shows better response than EA, but the recurrence rate after discontinuation of treatment requires further follow-up.

Pediatric urinary incontinence (PUI) is common in clinical practice and seriously affects the quality of life as well as physical and mental health of patients. PUI is a multi-factorial related abnormality, very complex in etiology and types. The occurrence of PUI is mostly associated with abnormal vesicourethral function. Urodynamic examination (UDS) is the golden standard to assess voiding function and diagnose the type of bladder and urethral function in children with PUI. UDS of PUI is of great clinical value in determining the cause, making treatment protocol as well as evaluating the therapeutic response. However, UDS in children has not been popularized in China, which seriously affects the diagnosis and treatment of PUI. This article reviews the research progress in the clinical application of UDS in the evaluation of PUI, in order to provide reference for improving the diagnosis and treatment of this disease.
