Objective To evaluate the reliability and validity of the Chinese version of the Repeatable Battery for the Assessment of Neuropsychological Status(RBANS)in patients with maintenance hemodialysis(MHD).Methods The general information and medical history of 84 MHD patients were collected,and the Mini-Mental State Exam(MMSE),Montreal Cognitive Assessment Scale(MoCA),and RBANS were conducted.The reliability of the scale was assessed by Cronbach α and split-half reliability.The structure and convergent validity of the scale were assessed by confirmatory factor analysis,and the RBANS scores'correlation to MoCA and MMSE scores was analyzed by Spearman correlation analysis.The predictive value of the RBANS total score on cognitive impairment(CI)was analyzed by receiver operating characteristic(ROC)curve.Results The Cronbach's alpha coefficient of the RBANS total scale was 0.896,split-half reliability was 0.911,and reliability for the five dimensions of the RBANS ranged from 0.618 to 0.791.Confirmatory factor analysis indicated that the overall fit of the five-dimensional model of the RBANS scale was acceptable(χ2/df=1.587,root mean square error of approximation=0.084,comparative fit index=0.967,incremental fit index=0.968,Tucker-Lewis index=0.947,goodness of fit index=0.891).The average variance extracted(AVE)for the five dimensions of the RBANS ranged from 0.525 to 0.863,while the composite reliability(CR)ranged from 0.733 to 0.926,indicating good convergent validity of the scale.Furthermore,Spearman correlation analysis revealed that the total RBANS score was negatively correlated to the age of MHD patients and positively correlated to years of education,as well as the total scores of MMSE and MoCA(all P<0.01).The ROC curve analysis indicated that the area under the curve(AUC)for the total RBANS score in predicting CI was 0.891(P<0.01),suggesting a high predictive value.Conclusion The Chinese version of RBANS has good reliability and validity in MHD patients,and can be used as a measure of cognitive function in MHD patients.

Objective:To investigate the expression of mismatch repair protein 2(MSH2)in gastric cancer and its correlation with patient clinical characteristics,as well as its effects on malignant biological behaviors of gastric cancer cells and underlying mechanisms.Methods:Tumor tissues and matched adjacent tissues were collected from 40 gastric cancer patients admitted to Xingtai People's Hospital from May 2020 to July 2022,along with patient clinical data.Normal gastric mucosal epithelial cells(GES-1)and gastric cancer cell lines(AGS,MKN45,and BGC-823)were routinely cultured.The sh-NC(negative control),shMSH2-1,and shMSH2-2 lentiviral vectors were transfected into AGS and MKN45 cells,respectively,dividing the cells into sh-NC,shMSH2-1,and shMSH2-2 groups accordingly.The proliferation,migration,and invasion capabilities of AGS and MKN45 cells in each group were assessed using CCK-8 assay,colony formation assay,Edu staining,and Transwell chamber assay,respectively.A nude mouse MKN45 cell xenograft model was established to evaluate the effect of MSH2 knockdown on tumor growth.WB was performed to detect the expression of MSH2,PI3K/AKT/mTOR pathway-related proteins,and epithelial-mesenchymal transition(EMT)-related proteins in cells and xenograft tissues.Results:MSH2 was highly expressed in gastric cancer tissues and cell lines,and this elevated expression was associated with lymph node metastasis,advanced T stage,and poor histological differentiation(all P<0.001).Successful knockdown of MSH2 expression was achieved in AGS and MKN45 cells(P<0.001).MSH2 knockdown significantly inhibited cell viability,Edu-positive cell ratio,colony formation,migration,and invasion ability of AGS and MKN45 cells(all P<0.001),as well as xenograft tumor growth(P<0.001).It markedly suppressed the expression of MSH2 protein,PI3K/AKT/mTOR pathway-related proteins,and N-cadherin protein(all P<0.001),while promoting E-cadherin expression(P<0.001)in both AGS,MKN45 cells and MKN45 xenograft tissues.Conclusion:MSH2 is highly expressed in gastric cancer tissues and cell lines and is associated with lymph node metastasis,advanced T-stage progression,and poor histological differentiation.Knockdown of MSH2 expression suppresses the malignant biological behaviors of AGS and MKN45 cells by inhibiting the PI3K/AKT/mTOR pathway,positioning MSH2 as a potential therapeutic target for gastric cancer management.

Objective:To investigate the consistency of trichoscopic fields in androgenetic alopecia (AGA) patients by using scalp medical pigmentation (SMP) ink as visual marker, as well as the safety and durability.Methods:A retrospective analysis was conducted on patients with AGA who visited the Medical Cosmetology Center, Hangzhou First People’s Hospital, Westlake University School of Medicine from April to August 2024. Trichoscopic images were captured immediately and three months after using SMP ink for visual marker. Each patient’s two trichoscopic images were imported into Photoshop CC 2019 software for processing to obtain the location information of the marker, the distance between the marker center and the image center, and pigments areas. Consistency of markers during repeated trichoscopy was evaluated by comparing distances between pigment center and image center. The difference in distance between the two time points (3-month distance minus immediate-post-marking distance) was defined as "distance difference". Patients were divided into the same-operator group and different-operator group based on whether the two trichoscopy examinations were performed by the same operator. The impact of operator changes on the consistency of markers during repeated trichoscopy was assessed by comparing the "distance difference" between the two groups. Additionally, patients were categorized into single-point, double-point, and triple-point groups according to the number of markers. The influence of marker quantity on consistency of the markers was evaluated by comparing the "distance difference" among these three groups. Pigment spread was assessed by comparing pigment actural area in repeated trichoscopic images. Adverse reactions and ink fading within three months were recorded. Statistical analysis was performed using SPSS 27.0 software.The normal distribution measurement data was expressed as Mean ± SD, and the non-normal distribution measurement data was expressed as M ( Q1, Q3). The Wilcoxon signed-rank test was applied for comparison of the distance between the marker center and the image center in the preceding and subsequent trichoscopic images. Mann-Whitney U test was applied for comparison between the same-operator group and the different-operator group, and the Kruskal-Wallis rank sum test was used for comparison among the single-point, double-point, and triple-point groups. The paired sample t-test was used for comparison of the pigment actural area during repeated measurements. P<0.05 indicated statistically significant differences. Results:A total of 22 male AGA patients (aged 24-43 years) were included, with 46 pigment points marked (8 single-point, 4 double-point, 10 triple-point). Same-operator and different-operator groups comprised of 13 and 9 patients, respectively. No significant difference was found in distances between marker center and image center immediately vs. 3 months post-marking [0.91 (0.62, 1.53) mm vs. 0.83 (0.62, 1.22) mm, Z=-0.83, P=0.408]. Comparisons of the "distance difference" between the same-operator and different-operator groups, and among the single-point, double-point, and triple-point groups, showed no statistically significant differences (all P> 0.05). Pigment areas increased by (0.11±0.12) mm 2 at 3 months ( t=-6.47, P<0.001). All pigments exhibited fading within 3 months but remained identifiable without touch-up. Adverse reactions were minimal: mild puncture-site bleeding was observed, with no pigment-related allergies, foreign-body reactions, or significant scarring. Conclusion:Single-point SMP pigment enables reliable and consistent visualization of trichoscopic measurement points in AGA patients, unaffected by operator changes. The method demonstrates clinical convenience, flexibility, high safety, and long-term durability.

Objective:To evaluate the clinical efficacy of infraorbital rim drilling midface lift combined with composite lower blepharoplasty.Methods:Retrospective analysis of clinical data from the patients who underwent combined midface lift and lower blepharoplasty at Department of Medical Cosmetic Center, Affiliated Hangzhou First People’s Hospital, Westlake University School of Medical, between January 2022 and February 2024.The infraorbital rim drilling midface lift combined with lower blepharoplasty was performed via a subciliary incision approach. Through a subciliary incision, the herniated orbital fat was excised, followed by fixation of the orbital septum to the infraorbital rim periosteum. Drill holes were created at the medial and lateral infraorbital rim, and arcuate suspension of the midface was performed using 2-0 absorbable sutures (SXPP1A405). Postoperative follow-up assessed midface lifting outcomes and complication rates. The wrinkle severity rating scale (WSRS) was used to grade nasolabial folds pre- and postoperatively (5-point scale: higher scores indicating more pronounced folds). Patient-reported outcomes were assessed using the Face-Q questionnaire, evaluating: (1) overall facial satisfaction, (2) satisfaction with surgical results, and (3) satisfaction with decision (scale 0-100; higher scores indicating greater satisfaction/less decisional regret). Descriptive statistical methods were employed for data analysis.Results:A total of 43 patients were enrolled, comprising 7 males and 36 females, with a mean age of (50.6±12.2) years (range: 32-73 years). Postoperative follow-up averaged (11.9±4.6)months. All patients demonstrated significant improvement in lower eyelid bags, tear trough deformity, midface elevation, and nasolabial folds. Surgical complications included: residual lower eyelid fat ( n=5), intermittent fixation point pain persisting >1 month ( n=4), mild residual tear trough deformity ( n=4), and hematoma ( n=1). Nasolabial fold WSRS scores decreased from ( 3.7±0.9 ) points to(2.9±0.6)points following surgery. In 38 patients, Face-Q scores demonstrated high satisfaction levels: appearance-related satisfaction scored (80.9 ± 10.3)points and satisfaction with decision scored (82.4 ± 8.9)points, indicating favorable patient-reported outcomes. Conclusion:The infraorbital rim drilling-assisted midface lift combined with comprehensive lower blepharoplasty effectively corrects midface ptosis while addressing lower eyelid bags. This technique provides reliable fixation points through drilling, resulting in stable and long-lasting lifting outcomes with high patient satisfaction.

Objective:To investigate the clinical efficacy of hair follicle-bearing microskin transplantation as a novel therapeutic approach for subacute wounds.Methods:A prospective randomized controlled trial was conducted from June to October 2024, involving patients with subacute wounds treated in the Department of Plastic and Reconstructive Surgery, Hand Microsurgery at Ningbo No.6 Hospital, and the Medical Aesthetics Center at Hangzhou First People’s Hospital. Participants were randomly assigned via a random number table into two groups: the observation group received hair follicle-bearing microskin transplantation, while the control group received conventional treatment including debridement, dressing changes, antimicrobial therapy, and local pressure relief. The observation endpoint was set at 6 weeks post-treatment. Outcome measures included time to complete wound healing, wound healing score (comprising five items: wound area, appearance, exudate, signs of infection, and condition of surrounding skin; total score 0-15, with a higher score indicating poorer healing), donor site recovery, adverse reactions, and patient satisfaction [rated on a 4-level scale: very satisfied, satisfied, basically satisfied, dissatisfied; satisfaction rate was calculated as (very satisfied + satisfied) cases/total cases×100%]. Data were analyzed using SPSS 25.0 software, with continuous variables expressed as Mean±SD and compared via t-test; enumeration data were expressed as cases (relative numbers) and analyzed using Fisher’s exact test. P<0.05 was considered statistically significant. Results:Sixteen patients were enrolled (8 per group), including 12 males and 4 females, with a mean age of 46 years (range: 41-71). No significant differences in baseline characteristics (gender, age, wound duration, and wound area) were observed between the two groups (all P>0.05). All procedures in the observation group were completed successfully without intraoperative or short-term postoperative complications. The donor site area was (28.2±11.8) cm 2 (9.0-50.0 cm 2). All wounds in the observation group healed completely within 2-5 weeks post-treatment, with a mean healing time of (26.2±5.0) d. The donor sites healed within two weeks, leaving only pinpoint scars. In contrast, only 4 cases in the control group achieved complete healing within the observation period (6 weeks post-treatment), with a mean healing time of (33.2±5.7) d. The other 4 patients showed no tendency to heal at 6 weeks and progressed to chronic wounds. Before treatment, no significant difference in wound healing scores was found between the two groups (9.6±2.6 vs. 9.1±2.0, t=0.43, P=0.676). At 6 weeks post-treatment, the observation group showed significantly lower wound healing scores than the control group (1.2±1.5 vs. 7.9±3.9, t=-4.48, P=0.001). At 6 weeks post-treatment, patient satisfaction in the observation group was significantly higher than that in the control group (8/8 vs. 4/8, P=0.006). Conclusion:Hair follicle-bearing microskin transplantation demonstrates significant clinical advantages in treating subacute wounds, including accelerated healing, improved aesthetic outcomes, minimal donor site morbidity, and rapid recovery.

Objective:To investigate the protocol and clinical efficacy of hair follicle-bearing microskin (HF-MS) transplantation in the treatment of hypertrophic scars.Methods:Prospective randomized controlled trial. From January to November 2024, patients with hypertrophic scars were recruited from the Medical Cosmetic Center of Affiliated Hangzhou First People’s Hospital with Westlake University School of Medicine and the Department of Plastic and Reconstructive Surgery of Ningbo Sixth Hospital. Patients were randomly divided into the observation group and the control group using a random number table. In the observation group, 1.0 mm punch decompression was performed on the hypertrophic scar area, followed by implantation of HF-MS extracted from the scalp donor site using follicular unit excision (FUE) into the decompression pores. The control group underwent only 1.0 mm punch decompression. Vancouver scar scale (VSS) scores (total score 0-15, higher scores indicating more severe scarring) were assessed preoperatively and at 1, 3, and 6 months postoperatively. Efficacy at 6 months, improvement in hypertrophic scar area, hair survival rate (observation group), adverse reactions, and patients’ satisfaction rates were evaluated. Categorical data were expressed as frequency (%) and analyzed using chi-square tests; normally distributed measurement data were expressed as Mean ± SD and analyzed using independent samples t-tests. Results:A total of 50 patients were included (25 per group), with 22 males and 28 females, aged 18-60 years (mean age: 33 years). The effective rate was 92% (23/25) in the observation group and 68% (17/25) in the control group, showing a statistically significant difference ( P<0.05). Preoperative VSS scores did not differ significantly between the observation and control groups [(6.67±3.19) vs. (7.12±2.89), P>0.05]. At 1, 3, and 6 months postoperatively, the observation group had VSS scores of (5.48±2.60), (4.64±2.39), and (3.80±2.10), respectively, compared to (6.36±2.53), (5.84±2.28), and (5.32±2.09) in the control group. The 6-month postoperative VSS scores differed significantly between groups ( P<0.05). Preoperative hypertrophic scar areas showed no significant difference [(5.75±2.83) cm 2 vs. (6.91±3.31) cm 2,P>0.05]. At 6 months postoperatively, the observation group had significantly smaller scar areas than the control group [(3.15±1.55) cm 2 vs. (5.37±2.93) cm 2,P<0.01]. The average hair survival rate in the observation group was 41% at 6 months. Adverse reactions occurred in 3 cases in the observation group (2 skin indurations, 1 hyperpigmentation) and 7 cases in the control group (4 hyperpigmentation, 2 skin atrophy, 1 skin induration). The observation group had a significantly lower adverse reaction rate [12% (3/25) vs. 28% (7/25), P<0.05]. Patient satisfaction rates were 88% (22/25) in the observation group and 64% (16/25) in the control group ( P<0.05). Conclusion:HF-MS transplantation demonstrates definitive clinical efficacy in treating hypertrophic scars, effectively improving scar morphology, clinical symptoms, and patient quality of life.
