Objective: To explore the learning curve of transurethral 450 nm blue light vaporization of the prostate (TUBVP) in a district hospital,in order to provide reference for clinicians who plan to perform TUBVP. Methods: The clinical data of 56 patients with benign prostatic hyperplasia (BPH) who received TUBVP performed by the same group of surgeons in Chang'an District Hospital during Jun. and Dec. 2023 were retrospectively analyzed. Cumulative sum (CUSUM) was used to fit the learning curve of ratio of volume to operating time (RVOT) of prostate volume /450 nm blue light. The learning curve was divided into different stages according to the inflection points,and the clinical data of patients operated at different stages were analyzed and compared. Results: The learning curve of TUBVP was 21 cases,including 1-21 cases in the learning stage,22-38 cases in the improvement stage and 39-56 cases in the maturity stage. With the increase of cases,the postoperative bladder irrigation time reduced \[40.00 (26.00,44.50) h vs. 23.00(20.50,34.00) h vs. 23.50(14.75,40.75) h\],with statistical difference (P<0.05). The surgical efficiency increased \[(0.51±0.14) vs. (0.55±0.17) vs. (0.63±0.23)\],while the reduction of hemoglobin \[(6.43±7.35) g/L vs. (5.65±10.91) g/L vs. (2.61±7.36) g/L\],catheter indwelling time \[70.0 (66.0,106.0) h vs. 71.0 (66.0,89.0) h vs. 66.0 (58.5,78.5) h\],and incidence of complications (9.5% vs. 5.9% vs. 0) in the three stages showed a gradually decreasing trend,but with no statistical significance (P>0.05). Conclusion: The learning curve of TUBVP is 21 cases. For clinicians in district hospitals,TUBVP is a worthy choice.

ObjectiveTo investigate the alleviating effect of calcium cyanamide (CaCN2) soil fumigation on replanting problems of Rehmannia glutinosa. MethodsNewly soil (NP) was used as the control group, while three treatment groups were established: replanted soil (RP), newly soil treated with CaCN2 (120 g·m², tillage depth 25 cm) (NPCC), and replanted soil treated with CaCN2 (RPCC). R. glutinosa was cultivated in all groups. At harvest, the tuber agronomic traits (number of enlarged roots, maximum root diameter, fresh weight, dry weight) were measured. The content of catalpol and rehmannioside D was quantified by ultra-high-performance liquid chromatography (UPLC) to evaluate medicinal quality. Rhizosphere soil available nutrients and enzyme activities were analyzed by assay kits. The community structure and composition of fungi and bacteria in rhizosphere soil were assessed via internal transcribed spacer 2 (ITS2) sequencing and 16S rDNA sequencing, respectively. ResultsCompared with NP, the RP group showed obviously reduced in tuber agronomic traits and quality indicators (P0.05). However, the RPCC group showed significant improvement in agronomic traits and a notable increase in rehmannioside D content compared to RP (P0.05). The contents of available phosphorus and potassium in RPCC and NP groups were obviously lower than those in RP (P0.05). The polyphenol oxidase soil (S-PPO) activity in RP was obviously lower than in NP (P0.05), while sucrose soil (S-SC), acid phosphatase soil (S-ACP), and S-PPO activities in RPCC were obviously higher than in RP (P0.05). Microbial richness and diversity in RP were obviously higher than in NP (P0.05), whereas no significant differences were observed between the RPCC and NP. The relative abundances of fungal genera Nectria, Myrothecium, Tomentella, and bacterial genus Skermanella were obviousl lower in RPCC and NP than in RP (P0.05). Correlation analysis that S-ACP activity was positively correlated with the content of rehmannioside D (P0.05). Fungal genera Engyodontium and Alternaria, and bacterial genera Pir4 lineage, Pirellula, Methyloversatilis, Brevundimonas, Ralstonia, and Acidibacter were obviously positively correlated with tuber dry weight (P0.05). Conversely, fungal genera Pseudaleuria, Nectria, Haematonectria, Ceratobasidium, and bacterial genera Streptomyces, Skermanella, RB41, Gemmatimonas, and Bacillus were obviously negatively correlated with dry weight (P0.05). The fungal genus Alternaria and bacterial genera Brevundimonas, Ralstonia, Acidibacter, and Dongia showed positive correlations with medicinal quality of R.glutinosa tuber, while fungal genera Pseudaleuria, Nectria, Stachybotrys, Fusarium, Gibberella, Ceratobasidium, and bacterial genera Sphingomonas, Skermanella, RB41, Gemmatimonas, and Bacillus were obviously negatively correlated (P0.05). ConclusionCaCN2 soil fumigation can significantly improve enzyme activities in replanted Rehmannia rhizosphere soil, enhance the utilization of available nutrients, reshape microbial community structure of replanted R.glutinosa at the family and genus level, and notably improve tuber agronomic traits and medicinal quality. This study provides a novel approach to alleviating replanting problems and offers insights for the integrated development of standardized cultivation techniques, including soil disinfection, nutrient-targeted regulation, and microbial inoculant application.

Given the increasing concern regarding antibacterial resistance, the antimicrobial properties of naphthoquinones have recently attracted significant attention. While 1,4-naphthoquinone and its derivatives have been extensively studied, the antibacterial properties of 5,8-dihydroxy-1,4-naphthoquinone derivatives remain relatively unexplored. This study presents a comprehensive in vitro and in vivo analysis of the antibacterial activity of 35 naturally sourced and chemically synthesized derivatives of 5,8-dihydroxy-1,4-naphthoquinone. Kirby-Bauer antibiotic testing identified three compounds with activity against methicillin-resistant Staphylococcus aureus (MRSA), with one compound (PNP-02) demonstrating activity comparable to vancomycin in minimum inhibitory concentration, minimum bactericidal concentration (MBC), and time-kill assays. Microscopic and biochemical analyses revealed that PNP-02 adversely affects the cell wall and cell membrane of MRSA. Mechanistic investigations, including proteomic sequencing analyses, Western blotting, and RT-qPCR assays, indicated that PNP-02 compromises cell membrane integrity by inhibiting arginine biosynthesis and pyrimidine metabolism pathways, thereby increasing membrane permeability and inducing bacterial death. In an in vivo mouse model of skin wound healing, PNP-02 exhibited antibacterial efficacy similar to vancomycin. The compound demonstrated low toxicity to cultured human cells and in hemolysis assays and remained stable during serum incubation. These findings suggest that PNP-02 possesses promising bioactivity against MRSA and represents a potential novel antibacterial agent.

Acquired dermal macular hyperpigmentation (ADMH) is a group of diseases clinically characterized by grayish-black macules and patches, with pigment predominantly deposited in the dermis. ADMH includes Riehl's melanosis, lichen planus pigmentosus, and erythema dyschromicum perstans/ashy dermatosis. In light of the remarkable similarities in both morphological and histopathological characteristics among this group of diseases, the academic community has recently proposed the new nosological term "acquired dermal macular hyperpigmentation" to achieve integration and unified classification of these related disorders. This review comprehensively elaborates on advances in the diagnosis and treatment of ADMH, including clinical manifestations, dermoscopic findings, pathological characteristics, and treatment progress.

Objective:
To evaluate the efficacy of a self-developed mobile augmented reality navigation system (MARNS) in guiding spinal level positioning during intraspinal tumor surgery based on a dual-error theory.
Methods:
This retrospective study enrolled patients diagnosed with intraspinal tumors admitted to Fujian Provincial Hospital between May and November 2023. The participants were divided into conventional x-rays and self-developed MARNS groups according to the localization methods they received. Position time, length of intraoperative incision variation, and location accuracy were systematically compared.
Results:
A total of 41 patients (19 males) with intraspinal tumors were included, and MARNS was applied to 21 patients. MARNS achieved successful lesion localization in all patients with an error of 0.38±0.12 cm. Compared to x-rays, MARNS significantly reduced positioning time (129.00±13.03 seconds vs. 365.00±60.43 seconds, p<0.001) and length of intraoperative incision variation (0.14 cm vs. 0.67 cm, p=0.009).
Conclusion
The self-developed MARNS, based on augmented reality technology for lesion visualization and perpendicular projection, offers a radiation-free complement to conventional x-rays.
