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.

Objective To compare the impact of NaClO and EDTA pretreatment on the enamel surfaces pore exposure rate,resin in-filtration effectiveness and shear bond strength between the enamel white spot lesions(WSLs)and resin composite.Methods A total of 104 sound premolars were selected for the study.4 mm×4 mm×2 mm enamel blocks from 64 sound premolars were cut in the center of the buccal surfaces of the teeth.All blocks were randomly divided into five groups:group SE(sound enamels as negative control);group DE(enamel blocks demineralised as positive control);group RI(resin infiltration);group N/RI(5.25％NaClO pretreatment and resin infiltration)and group E/RI(17％EDTA pretreatment and resin infiltration).The pore exposure rate of enamel surfaces and resin penetration depths were observed by scanning electron microscopy(SEM)and confocallaser scanning microscopy(CLSM)in each group.The remaining 40 premolars were cut from the cervical roots and the residual crowns were embedded in self-condensing resin ma-terial(buccal surfaces of the enamel exposed only).According to the grouping information,the samples were given the corresponding pretreatments and resin infiltration respectively and were bonded with a cylindrical resin cylinder on the buccal enamel surface for shear bond test.The shear bond strength and fracture modes were recorded and analyzed in each group.Results Compared to group RI,the pore exposure rate of the enamel surface,resin penetration depths,and percentage of resin penetration area in the N/RI and E/RI groups were significantly increased(P＜0.05).The shear bond strength of the samples in group SE was the highest,and the lowest in group DE.Compared to group DE,the shear bond strength in groups RI,N/RI,and E/RI was significantly increased(P＜0.05).Con-clusion Enamel surface pretreatment with 5.25％NaClO or 17％EDTA has been demonstrated to effectively enhance the enamel pore exposure rate,resin penetration depth and the shear bond strength between WSLs and resin composite.

Objective This study aimed to investigate the antimicrobial resistance profiles of bacterial strains isolated from pediatric intensive care units(PICU)in China for better antimicrobial therapy.Methods Clinical isolates were collected from 17 institutions,including tertiary care children's hospitals and pediatric department of tertiary general hospitals in China from January 1,2020 to December 31,2022.Antimicrobial susceptibility testing was carried out according to a unified protocol using Kirby-Bauer method or automated systems.Results were interpreted according to the breakpoints released by the Clinical and Laboratory Standards Institute(CLSI)in 2020.Results A total of 10 688 isolates were collected,including gram-positive organisms(39.2％)and gram-negative organisms(60.8％).The top three organisms were S.aureus(13.6％,1 453/10 688),A.baumannii(10.0％,1 067/10 688),and coagulase-negative Staphylococcus(9.9％,1 058/10 688).Multi-drug resistant organisms(MDROs)were very common in children.The prevalence of methicillin-resistant Staphylococcus aureus(MRSA),carbapenem-resistant Enterobacterales(CRE),carbapenem-resistant E.coli,carbapenem-resistant K.pneumoniae(CRKP),carbapenem-resistant A.baumannii(CRAB),and carbapenem-resistant P.aeruginosa(CRPA)was 41.1％,19.4％,8.8％,30.9％,67.4％,and 28.8％,respectively.Overall,more than 50％of Enterobacteriales isolates were resistant to cephalosporins,while nearly 25％of Enterobacteriales isolates were resistant to carbapenems.MDROs were highly resistant to commonly used antibiotics.More than 80％of CRE and CRAB strains were resistant to all beta-lactam antibiotics.CRE and CRAB showed low resistance rates to tigecycline and polymyxin.CRPA showed lower resistance rates to piperacillin,beta-lactamase inhibitor combinations than the resistance rates to third and fourth generation cephalosporins.All of the Staphylococcus and Enterococcus isolates were susceptible to vancomycin and tigecycline.None of PRSP strains isolated from meningitis and nonmeningitis samples were resistant to rifampicin,vancomycin,or linezolid.The prevalence of β-lactamase-negative ampicillin-resistant(BLNAR)strains was 43.3％in Haemophilus influenzae.Conclusions MDROs were prevalent in PICU.It is necessary to establish an effective multidisciplinary team(MDT)to control the antimicrobial resistance.

Objective:To explore the design and application effect of a home-based pulmonary rehabilitation checklist for postoperative lung cancer patients and to analyze the feasibility of this innovative rehabilitation approach.Methods:A prospective non-concurrent controlled study was conducted. Eighty postoperative lung cancer patients from the Department of Thoracic Surgery, Henan Provincial People's Hospital, were conveniently selected. According to the time of admission, postoperative lung cancer patients from April to June 2024 ( n=40) were assigned to the control group, while those postoperative lung cancer patients from August to October 2024 ( n=40) were assigned to the experimental group. The control group was given routine home-based pulmonary rehabilitation knowledge education upon discharge, while the experimental group was provided with the application of a home-based pulmonary rehabilitation checklist in addition to the routine home-based pulmonary rehabilitation knowledge education. Assessments were performed on the day of discharge and 1-month post-discharge using the Chinese version-Strategies Used by People to Promote Health (C-SUPPH), the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire-C30 (EORTC-QLQ-C30), the six-minute walk test (6MWT) and the Brog score. Results:A total of 40 patients in each group completed this study. Among them, there were 26 males and 14 females in the control group, aged (51.25 ± 11.39) years, and 23 males and 17 females in the experimental group, aged (53.07 ± 12.21) years. One month after discharge, the scores of positive attitude, self-decision making and self-stress reduction on the C-SUPPH in the experimental group were (44.25 ± 10.29), (30.76 ± 8.31) and (9.51 ± 2.17) points, respectively. They were higher than those in the control group (37.02 ± 7.14), (26.61 ± 6.71) and (7.58 ± 1.09) points, and the differences were statistically significant ( t=-3.65, -2.46, -5.03, all P<0.05). The scores of somatic function, role function, cognitive function and emotional function on the EORTC-QLQ-C30 in the experimental group were (65.77 ± 6.41), (71.46 ± 7.21), (70.11 ± 5.61) and (69.59 ± 5.71) points, respectively. They were higher than those in the control group (57.71 ± 7.01), (64.27 ± 5.25), (62.79 ± 7.18), (61.11 ± 6.25) points, and the differences were statistically significant ( t values were -6.34 to -5.08, all P<0.05). The 6MWT distance in the experimental group was (411.31 ± 35.02) m, which was higher than (376.58 ± 30.26) m in the control group, and the difference was statistically significant ( t=-4.75, P<0.05). The Brog score in the experimental group was (2.12 ± 0.68) points, which was lower than (2.50 ± 0.65) points in the control group, and the difference was statistically significant ( t=2.56, P<0.05). Conclusions:The implementation of home pulmonary rehabilitation list can improve the self-management ability of patients after lung cancer surgery, improve the quality of life, and then enhance the exercise ability, which is worthy of clinical promotion.

This consensus was developed by the Orthodontic Society of the Chinese Stomatological Association to provide a systematic, scientific, and practical guideline for informed consent in orthodontic care. Orthodontic treatment is typically lengthy, highly individualized, and involves multiple factors such as growth and development, occlusal function, and facial esthetics. Rapid technological advances and diverse risk profiles make the traditional reliance on orthodontist experience or institutional templates insufficient to ensure patients′ full understanding and autonomous decision-making. To address this, the expert panel conducted extensive reviews of domestic and international guidelines, analyzed representative dispute cases, and performed multicenter patient-clinician surveys. Using a multi-round Delphi method, the group established a standardized informed consent framework covering the initial consultation, treatment, and retention phases. The consensus emphasizes that informed consent is not only a fundamental legal and ethical requirement but also a key step in building trust, improving patient compliance, and enhancing treatment satisfaction. Orthodontists should clearly and comprehensively explain treatment plans, potential risks, uncertainties, and associated costs, while respecting the autonomy of patients or guardians, and maintain continuous communication and dynamic evaluation throughout the treatment process. The release of this consensus provides unified and authoritative guidance for clinical orthodontics, helping to standardize informed consent, enhance its transparency, safeguard patient rights, reduce medical risks, and promote high-quality, sustainable development of orthodontic practice.

AIM:This study aims to investigate the effects of Jiedu-Shengji ointment(JDSJG)on wound healing in diabetic rats by modulating the protein kinase R-like endoplasmic reticulum kinase(PERK)/inositol-requiring enzyme 1(IRE1)/nucleotide-binding oligomerization domain-like receptor protein 3(NLRP3)pathway in the context of endoplasmic reticulum stress(ERS).METHODS:Male Sprague-Dawley rats were randomly assigned to four groups:control group,model group,detoxification muscle ointment group,and sulfadiazine silver cream group.All groups,except the control,were administered an intraperitoneal injection of 45 mg/kg streptozotocin to induce diabetes.The control and model groups received daily applications of normal saline,while the detoxification myogen ointment and sulfadiazine silver cream groups received their respective treatments daily.After dressing changes,wounds were bandaged with sterile gauze.Following 14 d of continuous treatment,wound healing was assessed and healing rates calculated.Histopathologi-cal changes in wound tissues were analyzed using HE staining.Transmission electron microscopy was utilized to observe the number,morphology,and swelling of endoplasmic reticulum in the wound tissues.The expression and distribution of PERK,IRE1 and thioredoxin interacting protein(TXNIP)was assessed by immunohistochemistry,while Western blot was used to measure the levels of apoptosis-associated speck-like protein containing a caspase recruitment domain(ASC),TXNIP and NLRP3.ELISA was conducted to quantify the inflammatory cytokines interleukin-18(IL-18)and IL-1β.RE-SULTS:After 14 d of intervention,significant differences were observed in wound tissue parameters across the groups.The model group exhibited a significantly lower wound healing rate compared to the control group(P<0.01),with in-creased wound exudation,poor granulation tissue growth,and elevated the protein levels of PERK,IRE1,TXNIP,CHOP,NLRP3 and ASC(P<0.01),as well as significantly higher levels of IL-1β and IL-18(P<0.01).In contrast,the detoxification muscle ointment group showed a marked improvement in wound healing rate(P<0.01),reduced inflamma-tory exudation,improved granulation tissue growth,and significant decreases in TXNIP expression(P<0.01),along with lower levels of PERK,IRE1,CHOP,ASC and NLRP3(P<0.01).Additionally,the IL-1β and IL-18 were significantly reduced(P<0.01).CONCLUSION:Jiedu Shengji ointment alleviates excessive ERS and mitigates chronic inflammato-ry responses,thereby promoting the healing of diabetic wounds.These effects may be attributed to the inhibition of exces-sive activation of the PERK/IRE1/NLRP3 pathway.
