Objective:To compare the efficacy and safety of a domestic hair follicle extraction system versus traditional follicular unit excision (FUE) in extracting hair follicles for the treatment of androgenetic alopecia (AGA) .Methods:A multicenter, randomized, self-controlled clinical trial was conducted on AGA patients aged 18 - 59 years who were recruited from the Huashan Hospital, Fudan University, the Affiliated Hangzhou First People's Hospital, and the China-Japan Friendship Hospital between June 2023 and September 2024. Each patient's scalp was randomly divided into two sides (experimental side vs. control side) using an envelope method. The experimental side underwent robotic hair transplantation with a domestic hair follicle extraction system, and the control side underwent traditional FUE. Hair follicles were extracted from the safe donor area in the occipital region, and implanted into the ipsilateral hair loss area. The primary outcome was the hair transection rate which was calculated immediately after follicular extraction. The secondary outcomes included the hair follicle unit loss rate and the change in hair density at the recipient site on postoperative day 14. Safety was evaluated by assessing the incidence of folliculitis at the donor site on postoperative day 14 and the overall incidence of adverse events. Surgical outcomes were evaluated at 9 months after surgery. Comparisons of evaluation indicators among groups were performed by using a paired t test or Wilcoxon signed-rank test. Results:A total of 55 patients with AGA (51 males and 4 females, aged 32.71 ± 5.75 years) completed the hair follicle transplantation and postoperative follow-up. The hair transection rate ( M[ Q1, Q3]) was 6.65% (4.56%, 10.16%) in the experimental group and 5.28% (3.04%, 8.89%) in the control group (difference = 1.24%, 95% CI: -0.24%, 2.65%) . The hair follicle unit loss rate was 2.00% (1.00%, 3.50%) in the experimental group and 0.50% (0, 2.00%) in the control group, with a significant difference between the two groups ( P = 0.008) . On postoperative day 14, there was no significant difference in the hair density between the experimental group and control group (72.20 ± 25.95 per cm 2vs. 76.49 ± 30.84 per cm 2, P = 0.173) . At 9-month follow-up, both groups showed improvement in the investigator's overall score in the recipient areas. Seven adverse events occurred in 7 subjects (12.72%) in each group, and all were mild folliculitis. Conclusion:The domestic hair follicle extraction system demonstrated comparable efficacy and safety to the traditional FUE in hair transplantation.

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 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.

Objective:To investigate the safety and efficacy of submucosal tunnel docking endoscopic resection (SDER) for the treatment of giant submucosal tumors in the cardia.Methods:A retrospective analysis was performed on data of patients with giant submucosal tumors in the cardia who were treated with SDER at the endoscopy center of Zhongshan Hospital, Fudan University and Xuhui District Central Hospital from January 2021 to January 2022. The surgical records, postoperative pathology, complications, hospitalization, and follow-up were analyzed.Results:A total of 6 patients were included. The mean long diameter of the lesions was 4.0 cm, all of which were located in the cardia. All patients successfully underwent SDER treatment with a surgical time of 23-42 min. Postoperative pathology revealed that 4 cases were leiomyomas and 2 cases were gastrointestinal stromal tumors. All lesions were completely resected. The postoperative hospital stay was 3-5 d, and no serious complications occurred after surgery. All patients recovered on follow-up gastroscopy at 3 and 6 months postoperatively.Conclusion:The preliminary conclusion is that SDER for the treatment of giant submucosal tumors in the cardia is safe, effective.

Objective:To explore the applicability of the distance between facial marks classification in evaluating the severity of androgenic alopecia in men.Methods:From June to December 2019, the male Chinese with diagnosis of androgenic alopecia were evaluated in the specific clinic of alopecia of Hangzhou First People’s Hospital according to the distance between facial marks and BASP(basic and specific) classification. The classification based on the distance between facial marks measures the distance from the facial marks of the anterior hairline to the horizontal line of the eyebrow and the longest radius of hair loss in the hair rotation center, the hair recession of the patient’s forehead (F), temporal (M) and vertex (V) parts. The hair loss in each region is rated as 0-3 grade from light to heavy, and the final hair loss grading is expressed as FnMnVn, such as F1M2V0. The highest grade of hair loss in F, M and V is the overall grade of hair loss. SPSS 25.0 software was used to statistically analyze the general data of patients, and Kappa test was used to evaluate the consistency between the results of the distance classification and BASP classification. The repeatability of the distance classification was tested by the repetition rate of three hair loss specialists. When two or more specialists gave the same evaluation among the three hair loss specialists, the result was regarded as the standard result. The ease of use of the distance between facial marks classification was tested by the consistency rate between the grading results of two temporary trained general doctors and the standard results.Results:A total of 150 male patients, aged (32.8±7.9) years (19-58 years), were included, of which 99 patients were 24-35 years old, accounting for 66.00%. It can be observed that the onset age was earlier. As assessed in this classification, the patients who participated in the study were graded as mild in 65 cases(43.33%), severe in 58 cases(38.67%), and moderate, which was consistency with the results obtained by BASP classification ( κ=0.573, P<0.001). Three experienced alopecia specialists evaluated 150 patients through the distance between facial marks. The results showed that the repetition rates of frontal, temporal and parietal classification results were 98.00%(147/150), 97.33%(146/150) and 96.00%(144/150), respectively. The repetition rate of the final alopecia classification was 92.00%(138/150), and the repetition rate of the overall alopecia classification was 98.00%(147/150). The consistency rate between the overall alopecia classification results of two temporary trained general doctors and the standard results was 95.92%(141/147) and 96.60%(142/147), respectively, and the consistency rate of the other results was higher than 90.00% except for one general doctor who was 89.86%(124/138) in the final classification. Conclusion:The distance between facial marks classification is a comparatively accurate and easy-to-learn grading method designed for Chinese male androgenic hair loss patients based on objective measurement data.
