Abstract
BACKGROUND Due to several factors that affect photograph quality, bias is inevitably present in two-dimensional (2D) breast photography. The principal variables affecting image performance at a fixed focus length are the distance between the camera and the subjects and the photography angles. OBJECTIVE This study aimed to investigate the effects of camera-to-subject distances and camera height on breast measurement parameters to understand the trend of breast deformation and provide guidance for the accurate evaluation of planar follow-up. METHODS We enlisted 16 volunteers with various breast cup sizes (A-D). Frontal and lateral photos were obtained with a steady focus of 50 mm at distances between 1.10 m and 2.20 m and at heights between 30 cm above the nipple and 30 cm below the nipple at intervals of 10 cm. Two researchers independently evaluated each volunteer's breast aesthetic parameters, including 11 linear parameters, 3 area parameters, and 3 ratio parameters, using Vernier calipers and Photoshop. RESULTS The correlation coefficient of the two investigators ranged from 0.922 to 0.999. The results measured by Photoshop were 29.67 ± 5.23% greater than those of the Vernier caliper (p < 0.01). In contrast to ratio parameters, which showed no significant changes in each distance group (p = 1.00), linear parameters and area parameters significantly increased as object distance decreased (p < 0.05). The lower pole of the breast grew wider and flatter and occupied a larger proportion of the breast as height declined. CONCLUSION Camera-to-subject distances of 1.5-1.7 m are recommended for stabilized and uniform breast photography. Varying shooting height affects breast distortion. Quantifying the relationship between photographic conditions and breast morphology enables plastic surgeons to conduct more comprehensive and accurate assessments. LEVEL OF EVIDENCE IV This journal requires that authors assign a level of evidence to each article. For a full description of these Evidence-Based Medicine ratings, please refer to the Table of Contents or the online Instructions to Authors www.springer.com/00266. Bullet point list: 1. The breast morphology will get more distortion with a smaller camera-to-subject distance. 2. Camera-to-subject distances of 1.5~1.7m are recommended for stabilized and uniform breast photography. 3. Height rather than distance affects the breast proportion.

Abstract
AIM To investigate the feasibility of a radiomics nomogram model for predicting malignant transformation in sinonasal inverted papilloma (IP) based on radiomic signature and clinical risk factors. MATERIALS AND METHODS This single institutional retrospective review included a total of 143 patients with IP and 75 patients with IP with malignant transformation to squamous cell carcinoma (IP-SCC). All patients underwent surgical pathology and had preoperative magnetic resonance imaging (MRI) and computed tomography (CT) sinus studies between June 2014 and February 2022. Radiomics features were extracted from contrast-enhanced T1-weighted images (CE-T1WI), T2-weighted images (T2WI), and apparent diffusion coefficient (ADC) maps. The least absolute shrinkage and selection operator (LASSO) were performed to select the features extracted from the sequences mentioned above. Independent clinical risk factors were identified by multivariate logistic regression analysis. Radiomics nomogram was constructed by incorporating independent clinical risk factors and radiomics signature. Based on discrimination and calibration, the diagnostic performance of the nomogram was evaluated. RESULTS Twelve radiomics features were selected to develop the radiomics model with an area under the curve (AUC) of 0.987 and 0.989, respectively. Epistaxis (p=0.011), T2 equal signal (p=0.003), extranasal invasion (p<0.001), and loss of convoluted cerebriform pattern (p=0.002) were identified as independent clinical predictors. The radiomics nomogram model showed excellent calibration and discrimination (AUC: 0.993, 95% confidence interval [CI]: 0.985-1.00 and 0.990, 95% CI: 0.974-1.00) in the training and validation sets, respectively. CONCLUSION The nomogram that the combined radiomics signature and clinical risk factors showed a satisfactory ability to predict IP-SCC.

Abstract
MicroRNAs (miRNAs) play a crucial role in gene regulation and the development of keloid. This research aimed to identify and verify miRNAs associated with keloids by microarray analysis and in vitro experiments, shedding light on seeking for potential therapeutic molecular targets. In this study, the weighted gene co-expression network analysis was performed based on the GSE113620. The key miRNA module most relevant to the keloid was further screened to identify hub miRNAs, and then hub miRNAs was verified by the microarray analysis and qRT-PCR experiments. Additionally, targeted genes of hub miRNAs were predicted and verified. Gene ontology (GO) analysis and KEGG enrichment analysis were also conducted. Five miRNA modules were divided, and the blue module exhibited the highest correlation with keloids. Then, hsa-miR-127-3p, hsa-miR-214-3p, hsa-miR-155-5p, hsa-miR-409-5p, and hsa-miR-542-5p were identified as the hub miRNAs. Subsequently, the microarray analysis and qRT-PCR results demonstrated that the expression of five miRNAs were upregulated in keloid tissues. The GO analysis revealed that the target genes of these miRNAs were mainly enriched in biological processes including gene transcription, protein phosphorylation and the MAPK (mitogen-activated protein kinase) cascade, and the KEGG pathway enrichment analysis showed that the PI3K-AKT signaling pathway were significantly enriched. In conclusion, these five miRNAs (hsa-miR-127-3p, hsa-miR-155-5p, hsa-miR-214-3p, hsa-miR-409-5p, and hsa-miR-542-5p) play vital roles in the pathogenesis of keloid and might be potential therapeutic targets. These miRNAs might regulate genes enriched in gene transcription, protein phosphorylation, the MAPK cascade, and the PI3K-Akt signaling pathway.

Abstract
The chief aim of this paper is to response to the comment on "Is breast magnetic resonance imaging superior to sonography in gynecomastia evaluation and surgery planning" and reiterate the merit of breast MRI in gynecomastia treatment for its ability to improve our understanding of the anatomical structure of gynecomastia, which, in turn, aids in refining our surgical approach. All preliminary results shed light on the objective superiority of MRI over physical examination and sonography in evaluating the tissue components of gynecomastia. However, due to the inferiority of MRI over ultrasound in terms of cost, time consumption and accessibility, there is still a significant amount of progress to be made before MRI could be widely popularized.Level of Evidence IV This journal requires that authors assign a level of evidence to each article.

Abstract
BACKGROUND Each breast augmentation technique has advantages and indications, and the quest for the perfect implant pocket plane is ongoing. An ideal dual plane should meet three requirements: adequate implant coverage, optimal control of breast shape, and maximal muscle preservation. This paper reports a modified procedure for breast augmentation named subfascial mini muscle-release dual plane technique. METHODS From an inframammary or periareolar approach, the implant pocket is dissected in a subfascial plane up to the pectoralis major. The muscle is split 3 cm above the lateral margin and then pocket dissection proceeds in the submuscular plane. A small portion of the costal origin is divided inferomedially creating a dual plane. RESULTS A total of 178 patients with hypoplasia or breast atrophy were included, among whom 34 had breast ptosis and 20 had tubular breast deformity. The median follow-up period was 20 months. With an average implant volume of 268.8 ml and a smooth implant type of 85.4%, there was 1 case of hematoma, 2 cases of wound healing issues, 2 cases of rippling sign, 2 cases of grade III/IV capsular contracture, 5 cases of implant malposition and 12 cases of mild muscle contraction-associated deformity. Revision surgeries were performed on 2 patients. CONCLUSION The subfascial mini muscle-release dual plane technique is an easy method for breast augmentation and is especially indicated for ptotic breasts and tubular breast deformities. This technique combines the advantages of traditional dual plane and muscle-splitting techniques, yielding a satisfactory aesthetic outcome.

Abstract
PURPOSE There is little information on factors that influence the glycemic variability (GV) during the nocturnal and diurnal periods. We aimed to examine the relationship between clinical factors and GV during these two periods. METHODS This cross-sectional study included 134 patients with type 2 diabetes. 24-h changes in blood glucose were recorded by a continuous glucose monitoring system. Nocturnal and diurnal GV were assessed by standard deviation of blood glucose (SDBG), coefficient of variation (CV), and mean amplitude of glycemic excursions (MAGE), respectively. Robust regression analyses were performed to identify the factors associated with GV. Restricted cubic splines were used to determine dose-response relationship. RESULTS During the nocturnal period, age and glycemic level at 12:00 A.M. were positively associated with GV, whereas alanine aminotransferase was negatively associated with GV. During the diurnal period, homeostatic model assessment 2-insulin sensitivity (HOMA2-S) was positively associated with GV, whereas insulin secretion-sensitivity index-2 (ISSI2) was negatively associated with GV. Additionally, we found a J-shape association between the glycemic level at 12:00 A.M. and MAGE, with 9.0 mmol/L blood glucose level as a cutoff point. Similar nonlinear associations were found between ISSI2 and SDBG, and between ISSI2 and MAGE, with ISSI2 value of 175 as a cutoff point. CONCLUSION Factors associated with GV were different between nocturnal and diurnal periods. The cutoff points we found in this study may provide the therapeutic targets for beta-cell function and pre-sleep glycemic level in clinical practice.

Abstract
BACKGROUND Enhanced recovery after surgery (ERAS) has been proven to decrease the amount of opioid use and reduce postoperative pain for a variety of surgeries, including breast reconstruction. However, data on ERAS in breast augmentation is lacking. OBJECTIVES This study aims to investigate the effectiveness and safety of ERAS for breast augmentation. METHODS A standardized ERAS protocol was established with full consideration of all aspects of perioperative care. Patients undergoing implant-based breast augmentation were prospectively recruited between December 2020 and January 2023, and assigned to either the ERAS or non-ERAS group randomly. The primary outcome was the activity of daily living after surgery. The secondary was postoperative pain and other outcomes included time to freely elevation, vomiting frequency, the use of analgesics, and complications. RESULTS A total of 122 patients were included, with 70 in the ERAS group and 52 in the non-ERAS group. Compared to non-ERAS patients, ERAS patients had a shorter time to freely elevation of upper limbs (2.3 d vs. 5.5 d, P < 0.001). For ERAS patients, the pain scores were significantly lower on postoperative days 1 to 3, the activity of daily living index was significantly higher on postoperative days 1 to 3 and the opioids consumption was decreased (7.1 mg vs. 46.2 mg, P = 0.018). No difference was observed in complication and hospital costs between the two groups. CONCLUSION The ERAS protocol significantly reduced postoperative pain and the use of opioids and promoted a return to daily activities without increasing complications in breast augmentation.

Abstract
BACKGROUND The ageing in the mid-face involves volume deficiency in multiple anatomical units, including the zygomatic arch, infraorbital region, medial and lateral cheek and nasolabial fold (NLF). Hyaluronic acid (HA) is extensively used in the minimally invasive procedures of mid-face rejuvenation. OBJECTIVES MD CodesTM is proposed to perform combined treatment of multiple sites to reduce treatment variability and increase clinician success rates. Although the detailed procedure of this technique, aesthetic effects and complications have been disclosed, its anatomical information has yet to be discussed. This paper elaborated on the static and dynamic anatomical characteristics of MD CodesTM through cadaveric dissection and ultrasound imaging. METHODS Anatomical dissection and ultrasound imaging help us look back on the injection methods and anatomical principles of MD CodesTM. RESULTS The treatment is threefold: (1) the bolus injections, for lifting purposes, are performed at the most depressing point along the zygomatic arch, zygomatic eminence, the prominent optimal point in the zygomatic region, the most depressed point of upper NLF with 0.2-0.3 ml HA. (2) The linear injections, featuring facial contouring refinement, are performed at the deep fat pad of the medial cheek and infraorbital region with 0.4 ml HA. (3) The linear injections, featuring volume replacement, are performed at the subcutaneous fat layer of lateral cheek and NLF with 0.8 and 0.4 ml HA. CONCLUSIONS MD CodeTM is led by the principle of "less dosage and better effect", and a special injection sequence is formulated based on the anatomical characteristics. Ultrasound is a useful tool to make for a dynamic anatomical understanding of MD CodeTM and visualize the anatomical information such as layers and thicknesses.

Abstract
BACKGROUND Existing evaluation tools of tear trough deformity are based on subjective impression of clinicians. More accurate quantitative assessment methods are needed. This study aimed to propose a quantitative three-dimensional assessment method for the tear trough deformity in comparison with the Barton's grading system and apply it to the efficacy evaluation of orbital septum fat transposition. METHODS 117 healthy Chinese adults (234 eyes) were enrolled and divided into four groups according to the Barton's grading system. Three-dimensional facial images were captured using Vectra H1 handheld camera. 6 anthropometric landmarks were identified on each eye and 8 linear measurements were generated accordingly. Intra-observer reliability was determined and measurements were compared between groups. Pre- and post-operative three-dimensional measurements were compared in 19 patients who received lower blepharoplasty with orbital septum fat transposition. RESULTS The severity of tear trough was positively correlated with age (P < 0.001) but not BMI (P = 0.145) or gender (P = 0.280). Intra-rater reliability of the 8 linear measurements was excellent except for the vertical distance between the palpebrale inferioris margin and the tear trough below the pupillary center. Intergroup comparison showed that the horizontal distance between the lateral end of tear trough (P < 0.001) and medial canthus and the sagittal vector from tear trough point toward eyelid bag point (P = 0.009) increased with grade, while the vertical distance from mid-pupil to palpebrale inferioris margin decreased gradually (P = 0.001). Orbital septum fat transposition significantly improved the tear trough deformity as assessed by these three-dimensional measurements. CONCLUSIONS We demonstrated a novel quantitative evaluation method of the tear trough deformity using three-dimensional stereophotogrammetry and proved it to be valid and reliable. It showed good value of clinical application and might help with periorbital rejuvenation planning and outcome assessment.

Abstract
BACKGROUND Standardized photographic recording and anatomic evaluation are crucial to refined and comprehensive preoperative design and enhanced aesthetic effect of female genital cosmetic surgery. OBJECTIVES The authors aim to propose a standard photographic scheme and physical examination form for the anatomical assessment of patients undergoing female genital surgery. METHODS The scheme containing 2 positions (standing and lithotomy positions) and 11 views (1 frontal and 2 oblique views from standing position; 6 frontal views with labia minora open and closed, pulled to the opposite side, clitoral hood pushed up, posterior fourchette stretched; 2 oblique views from lithotomy position) (2P11V) is applied to record pre- and postoperative appearance of the vulva. The evaluation form is utilized to record characteristics of different anatomical subunits during photography. RESULTS Two hundred forty-five patients who underwent female genital surgery were enrolled in the research from October 2018 to October 2022. All the patients received preoperative and postoperative 2P11V photography with about 5-minutes' shooting time. Various anatomical variations containing hypertrophy and prolapse of mons pubis, redundant types of labia minora and clitoral hood, incremental exposure of clitoral glans, hypo- to hypertrophy of labia majora, disappearance of interlabial groove, hypertrophy of posterior fourchette, and relation of subunits were accurately documented. CONCLUSIONS 2P11V photographic scheme displays the isolated features of each organ and proportion relation among different parts of vulva. The standard photographic record and physical examination form offer detailed anatomical structure to surgeons and facilitate surgeons to carry out an accurate surgical design, which deserve to be promoted and applied.

Abstract
BACKGROUND Data on the value of magnetic resonance imaging (MRI) in the preoperative evaluation and surgery planning of gynecomastia are limited. The purpose of this study is to reveal MRI features and categories of gynecomastia and compare surgical outcomes following MRI and sonography as well as their diagnostic accuracy. METHODS The area of the gland and the whole breast on the transverse plane via nipple of MRI were measured to calculate the ratio between them. Areola, mass and branch patterns were categorized to represent three different gynecomastia type on MRI. 183 patients were included, with 38 in MRI group and 145 in sonography group. Diagnostic accuracy was assessed by the level of agreement between preoperative imaging findings and intraoperative observations. Surgical data, patients' satisfaction and complications were compared between the two groups. RESULTS MRI in 75 gynecomastic breasts demonstrated the average ratio of the gland to the whole breast was 10.6%±13.3%. The most common MRI categories were branch patterns (45.3%). The diagnostic concordance rate of MRI was higher than sonography (100% vs. 86.8%, p = 0.001). Among those junior surgeons, the length of surgery was reduced in MRI group (100 min vs. 115 min, p = 0.048). There was no difference in terms of patient's satisfaction and complication rate between MRI and sonography. CONCLUSION MRI was superior to sonography in diagnostic accuracy to assess the tissue components of gynecomastia and provided informative guidance especially for junior surgeons. Surgical outcomes were comparable regardless of the use of MRI or sonography for evaluation. LEVEL OF EVIDENCE IV IThis journal requires that authors assign a level of evidence to each article.

Abstract
BACKGROUND Although the efficacy of botulinum toxin type A (BoNT-A) has been shown to vary depending on injection layer, reconstitution volumes, and BoNT-A formulations, the impact of injection patterns has been rarely mentioned. This article compared the therapeutic effects in patients treated with BoNT-A with retrograde linear and traditional spot injection techniques. METHODS Twenty-eight participants were enrolled in a split-face, patient-blinded randomized clinical trial. Each patient received BoNT-A injected with linear injection technique on one side and with spot injection technique on the other side. Outcomes included the wrinkle improvement rates (WIR) of the two injection techniques determined by the wrinkle scores derived from Antera 3D camera, the muscle activity assessed via ultrasound, and patient-reported pain rating on a numeric pain rating scale (NRS). RESULTS All participants completed the study. For forehead wrinkles, WIR on the linear side was significantly larger than that on the spot side at 1 week and 1 month (p<0.02). For glabellar wrinkles, WIR on the linear injection side was significantly larger than that on the spot side at 1 week (p=0.04). However, for periorbital wrinkles, WIR on the spot side was significantly larger than that on the linear side at 1 week (p<0.03). No significant difference was observed between the injection patterns in terms of muscle contraction and NRS scores. CONCLUSIONS Compared with the traditional spot injection, the retrograde linear injection shows to be superior in reducing forehead lines and glabellar lines, but less effective in reducing periorbital lines when identical dosages were injected.

Abstract
BACKGROUND Adolescence is a unique group in labia minora hypertrophy patients. As a result, the necessity and the benefit of labiaplasty in adolescents are still controversial. OBJECTIVES The purpose of this study is to summarize the surgical indications, the particularity of the treatment procedure, postoperative complications, and therapeutic outcomes of labiaplasty in the adolescent population. METHODS A retrospective chart review was performed of teenage patients (<18 years old) who underwent labiaplasty between January 2016 and May 2022. Patient characteristics, surgical method, concomitant procedures, procedure side, operative time, complications and follow-up data were recorded. RESULTS A total of 12 patients aged less than 18 years were included in this study. All procedures were performed for functional reasons. The average operation time was 61.75 ± 20.77 (38-114) min. Unilateral labia minora hematoma within 24 hours occurred in 2 (16.7%) patients and surgical evacuations were performed immediately. All patients were followed up electronically in 42.33 ± 16.88 (14-67) months. Notably, 83.33% (10/12) patients reported being very satisfied, and 16.67% (2/12) patients were satisfied. There was no patient dissatisfaction. Preoperative discomfort was completely resolved in 9 (75.00%) patients and significantly improved in 3 (25.00%) patients. Furthermore, no patients indicated that symptoms were not improved or worse. CONCLUSIONS In the adolescent population, severe hypertrophy of the labia minora and the clitoral hood will cause discomfort, affecting the quality of life and mental health. Therefore, labiaplasty is a safe and effective procedure in adolescents to improve the patient's genital appearance and quality of life.

Abstract
BACKGROUND Multiple muscles contribute to the formation of dorsal nasal lines (DNL) and affect nasal aesthetics. Few attempts have been made to explore the distribution difference of DNL in relation to injection planning. OBJECTIVES The authors aim to classify the distribution types of DNL and propose a refined injection technique validated by clinical study and cadaver dissection. METHODS Patients were classified into four types according to the distribution types of DNL. Botulinum toxin type A injections were administrated at six regular points and two optional points. The effect on wrinkle reduction was assessed. Patient satisfaction was recorded. Cadaver dissection was conducted to explore the anatomical evidence of the variations of DNL. RESULTS The study included 349 treatments in 320 patients (269 females and 51 males), whose DNL were classified into complex type, horizontal type, oblique type, and vertical type. The severity of DNL was significantly reduced after treatment. Most patients were satisfied. From the cadaver study, connecting muscular fibers were clearly observed among the muscles involved in the formation of DNL, and these muscles were collectively named as dorsal nasal complex (DNC) by the authors. Four anatomical variations of DNC were discovered, corroborating the classification system of DNL. CONCLUSIONS A novel anatomical concept "Dorsal Nasal Complex" and a classification system of DNL were proposed. Each of the four distribution types of DNL corresponds to a specific anatomical variation of DNC. A refined injection technique for DNL was developed, and its efficacy and safety were demonstrated.

Abstract
BACKGROUND The inframammary approach is one of the most commonly used incisions in breast augmentation. There are many suture methods for inframammary incisions; however, no one method has proven optimal. We modified the traditional three-layer suture method according to the inframammary fold (IMF) cadaver dissection results. This study aims to investigate whether using a modified suture method can improve postoperative outcomes. METHODS Cadaver dissections were performed in order to clarify the anatomy of the IMF. From June 2013 to December 2017, a retrospective study of primary breast augmentation patients subjected to the inframammary approach was conducted. Patients were divided into two cohorts: the traditional suture method and the modified suture method. The patient's demographics, specifics of breast augmentation procedures, complications, and scar assessment were analyzed. Univariate and multivariable analyses were used to determine differences between the two cohorts. RESULTS One hundred eighty-four patients were included: 75 patients were subjected to the traditional suture method, and 109 patients were subjected to the modified suture method. Wound-related adverse events (p = 0.026) and IMF-indented scarring (p = 0.014) were significantly different between the two groups. Multivariable analysis showed that the suture method was the most influential factor related to IMF-indented scarring (OR = 16.9), followed by BMI (OR = 2.9). CONCLUSIONS We defined a new suture method for the inframammary incision in primary breast augmentation. This modified suture method reduces the occurrence of wound-related adverse events and IMF-indented scarring.

Abstract
BACKGROUND Botulinum toxin type A (BoNT-A) injection is a popular cosmetic procedure in East Asian countries, and there are multiple types of toxins on the market. Whether different toxin types induce different changes in the masseter has not been studied. OBJECTIVE We aimed to investigate and compare the changes induced by injection of different types of BoNT-A in the masseter. METHODS Upon retrospective review of clinical records and routine ultrasound examination results of patients who underwent BoNT-A injection, four groups were set for comparison: unapproved toxin, OnabotulinumtoxinA, LanbotulinumtoxinA, and non-injected. Clinical records and ultrasound images were collected. Ultrasound images were taken in both horizontal and coronal planes. Elasticity of the masseter muscle was also investigated by measuring the surface wave speed. RESULTS A total of 24 patients were included (six patients per group). All patients were young females. For the non-injected group, the deep inferior tendon was clear and the muscle bundles were arranged, with little fibrous content. Patients who received unapproved toxin injection showed highly disarranged muscle and fiber bundles, with much fiber content present. The changes in OnabotulinumtoxinA and LanbotulinumtoxinA groups were in between those in the non-injected and unapproved toxin groups. Muscle rigidity was the highest in the unapproved toxin group, and generally higher in injected groups compared with the non-injected group. CONCLUSION Different types of BoNT-A may induce different changes in the masseter.

Abstract
Objective: To analyze the changes in self-efficacy and its influencing factors in type 2 diabetic patients after community-based self-management group intervention. Methods: From August to November 2014, a 3-month community-based self-management intervention study of type 2 diabetes patients was implemented in Fangshan District, Beijing. 510 patients were recruited through posters, household inquiries and telephone notification and then were randomly divided into intervention group (260 patients) and control group (250 patients). Finally, 500 patients completed the study, including 259 in the intervention group and 241 in the control group. Self-efficacy score was measured through face-to-face interview at different time points, including pre-intervention, post-intervention, 2 years after the intervention and 5 years after the intervention, respectively. A two-level random coefficient model was fitted to analyze the long-term trend of self-efficacy and its relationship with group intervention. Results: Individual-level educational attainment, disease duration as well as their treatment plans had a positive correlation with self-efficacy of type 2 diabetic patients while gender and age did not affect their self-efficacy. Patients with junior middle school education, senior high school education and university and above education had 4.66 (P<0.05), 6.40 (P<0.05) and 11.02 (P<0.05) points higher than those with primary education, respectively. The self-efficacy of diabetic patients increased by 0.23 (P<0.05) for each additional course year. The effect of treatment plan on self-efficacy was mainly reflected in the self-efficacy of taking medication or insulin injection as prescribed and blood glucose monitoring. After controlling for the confounding factors, i.e., gender, age, disease duration, educational attainment, and treatment plan, self-efficacy scores at the post-intervention increased in both groups compared to those at the pre-intervention. The intervention group had 7.95 points higher than the control group (P<0.05). After the intervention, the self-efficacy scores of both groups decreased year by year while the intervention group declined faster, with 5.41 points (P<0.05) at 2 years after the intervention and 8.94 points (P<0.05) at 5 years after the intervention. Conclusion: Community-based self-management group intervention could improve the self-efficacy of type 2 diabetic patients while the self-efficacy decreases year by year in the absence of follow-up intervention.

Abstract
BACKGROUND Vaginal laxity, usually accompanied with prolapse symptoms, affects women's sexual satisfaction and quality of life. Vaginal tightening surgery aims to reinforce the peri-vaginal muscle strength and restore the normal vaginal anatomy. OBJECTIVES The objective of this study was to introduce a new surgical approach with vaginal tightening using acellular dermal matrix (ADM). METHODS In this retrospective study, we analyzed data from 80 patients with vaginal laxity who underwent surgery from April 2017 to April 2021. Three-dimensional transvaginal ultrasound (3D-TVS) and the Female Sexual Function Index (FSFI) were evaluated among the patients. RESULTS The mean age of the patients was 44.6 years. The mean patient follow-up was 13.2 months. No infection, rectovaginal fistula, or implant explantation occurred. 3D-TVS demonstrated a significant reduction of introital diameter on a maximum Valsalva maneuver (2.3 cm vs. 4.1 cm; p<0.05) and the reconstruction of acute vaginal angulation. FSFI orgasm subscore increased significantly. CONCLUSIONS Vaginal tightening with ADM is a minimally invasive surgery with safety and efficacy for patients with vaginal laxity.

Abstract
BACKGROUND Existing classification neglected integrity of the clitoral hood-labia minora complex (CLC) and various anatomic variations, resulting in the failure to optimize a tailored approach to individuals. OBJECTIVES In this study, we presented a new classification system for comprehensive evaluation of the CLC variations and introduced a simple surgical approach for the fused type. METHODS We classified the anatomic variations of the CLC as three types. Type 1 was the isolated labia minora or lateral clitoral hood hypertrophy. Type 2 was the conventional combined hypertrophy. Type 3 was the fused lateral clitoral hood and labia minora. The modified procedure for the fused type was performed in four steps: the anterior border of labia minora was defined first, then the hypertrophic lateral clitoral hood and labia minora were removed separately, and finally the junction region was trimmed. Satisfaction questionnaires were conducted during follow-ups. RESULTS Among all 301 patients (602 sides), type 2 was the most common variation (285 sides, 47.3%). Type 3 variations in 67 patients (105 sides, 17.5%) were identified, and 77.6% of the patients answered the questionnaires 3 months after surgery. The satisfaction rate in the four-step excision group was 91.7%, which was significantly higher than that in the wedge excision group (56.3%) (P =0.01). The complication rate of the four-step excision was 2.5%. CONCLUSIONS Preoperative evaluation based on the new classification facilitated recognition of the variations of CLC, especially of the fused type. The four-step excision is a simple, effective and safe approach to treat the fused variation with high satisfaction.

Abstract
OBJECTIVE To estimate the incidence of urinary incontinence (UI), including its subtypes stress UI (SUI), urgency UI (UUI) and mixed UI (MUI), and to examine risk factors for de novo SUI and UUI in Chinese women. DESIGN Nationwide longitudinal study. SETTING Six geographic regions of China. PARTICIPANTS Women aged ≥20 years old were included using a multistage, stratified, cluster sampling method. METHODS This study was conducted between May 2014 and March 2016, with follow up in 2018. Data on demographics, medical history, lifestyle and physiological and anthropometric information were collected. MAIN OUTCOME MEASUREMENTS Incidence, rate ratio (RR). RESULTS Analyses included 24 985 women (mean age 41.9 years).The follow-up response rate was 55.5%, median follow-up time was 3.7 years. The standardised incidences of UI, SUI, UUI and MUI were 21.2, 13.1, 3.0 and 5.1 per 1000 person-years, respectively. Risk factors for de novo SUI included delivery pattern (vaginal spontaneous delivery RR 2.12, 95% CI 1.62-2.78 and instrumental delivery RR 3.30, 95% CI 1.99-5.45), high body mass index (BMI) (overweight RR 1.52, 95% CI 1.33-1.74 and obesity RR 1.67, 95% CI 1.32-2.11), cigarette smoking (RR 1.54, 95% CI 1.12-2.12), chronic cough (RR 1.44, 95% CI 1.17-1.76), diabetes (RR 1.33, 95% CI 1.10-1.60) and older age (50-59 years RR 1.49, 95% CI 1.16-1.90 and 60-69 years RR 1.61, 95% CI 1.22-2.13).The risk factors significantly associated with de novo UUI were age (RR increased from 1.21, 95% CI 0.74-1.99, at 30-39 years to 6.3, 95% CI 3.85-10.30, at >70 years) and diabetes (RR 1.48, 95% CI 1.05-2.09). CONCLUSIONS The incidence of female UI is 21.2 per 1000 person-years in China. Delivery (vaginal spontaneous delivery, instrumental delivery), high BMI, cigarette smoking, chronic cough, diabetes and older age were risk factors. TWEETABLE ABSTRACT The incidence of female urinary incontinence was 21.2 per 1000 person-years in China. Delivery, BMI, diabetes and old age are risk factors.

Abstract
BACKGROUND Nipple-areola complex is a naturally hyperpigmented skin area which can be involved in vitiligo. But limited study focused on the treatment of nipple-areola complex vitiligo, and few methods were proven to be effective. In this study, we aimed to explore the feasibility and efficacy of ReCell® on vitiligo in the nipple-areola complex area. METHODS Medical records of patients with vitiligo involving nipple-areola complex and underwent ReCell® treatment from October 2016 to April 2020 were retrospectively reviewed. The repigmentation rate of the nipple-areola complex and other breast area were calculated under the Wood's light at each follow-up. The grade of repigmentation and patient-reported satisfaction rate were also evaluated to prove the effect of ReCell® on vitiligo of breast and especially in the nipple-areola complex area. RESULTS A total of 18 patients were included in this study. No surgical complications were reported. The mean postoperative repigmentation rate in the nipple-areola complex area (3rd-month, 78.7 ± 5.8%; 6th-month, 87.6 ± 5.1%; and 12th-month, 96.1 ± 3.5%) was significantly higher than that in the other breast treatment area (3rd-month, 70.4 ± 6.9%; 6th-month, 84.2 ± 5.7%, and 12th-month, 93.2 ± 3.6%). All patients showed good or excellent grades at the last follow-up, and 94.4% of them considered the overall treatment results satisfactory. CONCLUSIONS ReCell® is a feasible and efficient treatment strategy in the nipple-areola complex vitiligo.

Abstract
Objective: To evaluate the quality of the National Demonstration Area for Comprehensive Prevention and Control of NCDs (referred to as "the Demonstration Area"). Methods: Based on the evaluation scores of the Demonstration Area field survey from 2017 to 2019, we counted the scores of each indicator, comparing the scores among indicators and regions. x±s was used to describe the scores. The 95%CI of the score was used to test the statistical difference among regions. Each score was converted into a hundred-mark system to compare the scores among indicators. Results: Of 236 Demonstration Areas, the total score was 83.5. The scores of the first-level indicator listed from high to low appeared as Integrating System of NCD Prevention and Control (92.8), Policy Perfection (90.3), Building Supportive Environment for NCD Prevention and Control (88.4), Implementation of Health Education and Health Promotion (87.4), Whole-course Management of NCDs (78.1), Innovation and Guidance (76.5), Surveillance and Evaluation (75.1). Total scores were higher in the east (259.2±18.8) comparing to the middle (243.2±15.2) or the west (245.4±19.7) regions. Conclusions: Substantial variations on the quality in the Demonstration Area existed across different regions in China. These disparities are important to the government when developing health policies and allocating resources. Whole-course Management of NCDs, Surveillance and Evaluation, and Innovation and Guidance in the Demonstration Area also needs to be improved.

Abstract
BACKGROUND Progressive pseudorheumatoid dysplasia (PPD) is a rare disease that causes musculoskeletal deformities. There has been no detailed report on the outcome of PPD patients who undergo total hip arthroplasty (THA). The aim of this study was to investigate the clinical and radiological outcome of PPD patients undergoing THA after middle-term follow-up. METHODS This was a medical records review study. Patients with the diagnosis of PPD who underwent THA were enrolled. The PPD diagnosis was confirmed by genetic sequencing. Baseline clinical data were retrieved. The patients were followed for the Harris Hip Score, visual analogue score, range of hip motion, and postoperative complication. Life quality was evaluated with the Short Form 36. Plain x-ray films were used for radiographic evaluation. RESULTS Four cases were identified from the patient database in our institute. All the patients presented arthropathy of both hips and underwent 1-stage bilateral THA. All the patients had WISP3 mutation after genetic sequencing. The cases were followed at average 47.9 months (range, 18-93 months). Harris Hip Score increased from 39.67 ± 9.73 points preoperatively to 91.67 ± 4.32 points postoperatively (p < 0.05); Short Form 36 increased from 19.67 ± 1.53 points preoperatively to 71.33 ± 3.06 postoperatively (p < 0.05). The hip range of hip motion was significantly improved after operation. X-ray films showed no obvious radiolucent lines or aseptic loosening at the latest follow-up. CONCLUSIONS This study indicated that THA was effective to treat the PPD patients complicated with hip arthropathy with satisfactory clinical and radiological outcome after mid-term follow-up.

Abstract
Electrons in moiré flat band systems can spontaneously break time-reversal symmetry, giving rise to a quantized anomalous Hall effect. In this study, we use a superconducting quantum interference device to image stray magnetic fields in twisted bilayer graphene aligned to hexagonal boron nitride. We find a magnetization of several Bohr magnetons per charge carrier, demonstrating that the magnetism is primarily orbital in nature. Our measurements reveal a large change in the magnetization as the chemical potential is swept across the quantum anomalous Hall gap, consistent with the expected contribution of chiral edge states to the magnetization of an orbital Chern insulator. Mapping the spatial evolution of field-driven magnetic reversal, we find a series of reproducible micrometer-scale domains pinned to structural disorder.

Abstract
Objective To determine the prevalence, risk factors and burden of symptomatic pelvic organ prolapse (POP) in adult Chinese women. Design A nationwide cross‐sectional study. Setting Six geographic regions of mainland China. Participants Women aged ≥20 years old were included using a multistage, stratified, cluster sampling method from February 2014 through March 2016. Methods We conducted a nationwide epidemiological survey. ‘Symptomatic POP’ was determined by a screening questionnaire and physical examination. Main outcome measurements Prevalence, odds ratio (OR). Results A total of 55 477 women (response rate, 92.5%; mean age, 45.1 years old) were included. The prevalence of symptomatic POP was 9.6% (95% CI 9.3–9.8%) and it increased with age in each stage (P < 0.05). Symptomatic POP‐Q stage II, which mainly involved anterior compartment prolapse, was the most common (7.52%). Minor/moderate burden of symptomatic POP was the most common, with a prevalence of 9.7% (95% CI 9.5–10.0%). The odds for each type of symptomatic POP increased with age (>50 vs 20‐29 years old in symptomatic POP‐Q stage II or higher, OR increased from 1.34 [95% CI 1.32–1.45] to 7.34 [95% CI 4.34–12.41]) and multiple vaginal deliveries (multiparous [≥3] vs nulliparous in symptomatic POP‐Q stage II or higher, OR increased from 1.91 [1.71–2.13] to 2.78 [2.13–3.64]). Conclusions We found a lower prevalence of symptomatic POP than that found in other surveys. The main type of symptomatic POP was anterior compartment prolapse, indicating that it should be considered first. Older age and multiple vaginal deliveries increased the odds of each type of symptomatic POP. Tweetable abstract The prevalence of female symptomatic pelvic organ prolapse (POP) was 9.6% in China. It is related to old age and multiple vaginal deliveries. The prevalence of female symptomatic pelvic organ prolapse (POP) was 9.6% in China. It is related to old age and multiple vaginal deliveries.

Abstract
OBJECTIVE To investigate the relationship between the meniscal defect area and OA progression and explore the effect and mechanism of SMSCs cell therapy in knee osteoarthritis (OA) rat model. MATERIALS AND METHODS For animal experiments, knee osteoarthritis (OA) model was constructed in Sprague Dawley (SD) rats by removing the medial meniscus of the right knee. Synovial mesenchymal stem cells (SMSCs) were engrafted by injecting into the right knee cavity. For in vitro experiments, CCK-8 assay was performed to evaluate the proliferation and differentiation of BMSCs and ATDC5 cells after co-cultured with SMSCs. qRT-PCR analysis was performed to detect the expressions of chondrogenic genes in BMSCs and ATDC5 cells after co-cultured with SMSCs. Western blot analysis was conducted to detect the phosphorylations of c-Jun N-terminal kinase (JNK) and extracellular regulated protein kinases (ERK) in MAPK signaling of BMSCs and ATDC5 cells. Enzyme-linked immunosorbent assay (ELISA) was performed to detect the serum levels of interleukin (IL)-1β, IL-1β, IL-6, IL-18 and C-reactive protein (CRP). RESULTS Results showed that meniscus damaged area is positively correlated to serum inflammatory factor levels. In vitro study showed that the proliferation and differentiation of BMSCs and ATDC5 cells were promoted after co-cultured with SMSCs. By co-culturing with SMSCs, the MAPK signaling pathway was activated and the expression of chondrogenic markers such as aggrecan (acan), SRY-related high mobility group-box gene 9 (sox9) and Type II collagen a1 (col2a1), was up-regulated both in BMSCs and ATDC5 cells. In vivo study showed SMSCs cell therapy significantly decreased serum inflammatory factor levels and protected cartilage by upregulating the expression of chondrogenic genes of meniscus chondrocytes derived from OA rats. CONCLUSIONS For the first time, we found the positive correlation between meniscal defect area and OA progression and demonstrated the effect and mechanism of SMSCs cell therapy in knee osteoarthritis (OA) treatment.

Abstract
BACKGROUND Due to adipose-derived stem cells (ASCs) being easy to obtain, their rapid proliferation rate, and their multidirectional differentiation capabilities, they have been widely used in the field of regenerative medicine. With the progress of decellularized adipose tissue (DAT) and adipose tissue engineering research, the role of DAT in promoting angiogenesis has gradually been emphasized. METHODS We examined the biological characteristics and biosafety of DAT and evaluated the stem cell maintenance ability and promotion of growth factor secretion through conducting in vitro and in vivo studies. RESULTS The tested ASCs showed high rat:es of proliferation and adhered well to DAT. The expression levels of essential genes for cell stem maintenance, including OCT4, SOX2, and Nanog were low at 2-24 h and much higher at 48 and 96 h. The Adipogenic expression level of markers for ASCs proliferation including PPARγ, C/EPBα, and LPL increased from 2 to 96 h. Co-culture of ASCs and DAT increased the secretion of local growth factors, such as VEGF, PDGF-bb, bFGF, HGF, EGF, and FDGF-bb, and secretion gradually increased from 0 to 48 h. A model of full-thickness skin defects on the back of nude mice was established, and the co-culture of ASCs and DAT showed the best in vivo treatment effect. CONCLUSION The application of DAT promotes wound healing, and DAT combined with ASCs may be a promising material in adipose tissue engineering and regenerative medicine.

Abstract
The positive influence of animal-based protein supplementation during muscle-damaging exercise has been widely studied. However, the effects of plant-based proteins remain unclear and require further clarification. This study investigated the protective role of oat protein against exercise induced muscle damage (EIMD), subsequent inflammation, and loss of performance induced by downhill running. Subjects consumed either oat protein (25 g protein) or a placebo for 14 days prior to a downhill running test and then for 4 days thereafter. Treatments with oat protein for 19 days markedly alleviated eccentric exercise induced skeletal muscle soreness, and reduced the elevation of plasma IL-6 concentrations and serum creatine kinase, myoglobin and C reactive protein contents. In addition, oat protein supplementation significantly inhibited limb edema following damaging exercise, and the adverse effects on muscle strength, knee-joint range of motion, and vertical jump performance were lessened. Furthermore, the administration of oat protein facilitated recovery from exhaustive downhill running in this study. These findings demonstrated that oat protein supplementation has the potential to alleviate the negative effects of eccentric exercise in untrained young males.

Abstract
OBJECTIVE This study aimed to assess the prevalence and factors associated with symptomatic pelvic organ prolapse (POP) in a representative sample of postmenopausal Chinese women. METHODS A total of 20,008 postmenopausal Chinese women were recruited to this cross-sectional study between February 2014 and March 2016. The prevalence of symptomatic POP, defined as any stage II or higher POP resulting in symptoms, was assessed using questionnaires and physical examinations. Multivariable logistic regression was used to assess factors associated with symptomatic POP. RESULTS Among all women with natural menopause included in the study (mean age =61.98 ± 10.62 years), 2962 of 20,008 women (14.80%, 95% confidence interval [CI] 14.3-15.3%) had symptomatic POP. In the multivariate analysis, women were more likely to have symptomatic POP if aged 50-59 years (adjusted odds ratio [AOR] 1.322, 95% CI 1.123-1.560), 60-69 years (AOR 1.603, 95% CI 1.352-1.907), or above 70 years (AOR 1.824, 95% CI 1.158-2.197), compared with women aged 40-49 years. Having delivered two times (AOR 1.145, 95% CI 1.105-1.292) or three or more times (AOR 1.384, 95% CI 1.214-1.578) was significantly associated with symptomatic POP. Compared with normal weight women, overweight women (AOR 1.365, 95% CI 1.247-1.494) and obese women (AOR 1.548, 95% CI 1.344-1.780) were more likely to have POP. Living in an urban area, smoking, alcohol consumption, cough, constipation, mental labor, physical disease, and gynecological diseases were also associated with symptomatic POP. CONCLUSIONS Symptomatic POP affects nearly 15% of postmenopausal women in China. The prevalence of symptomatic POP increases significantly with age, body mass index, and parity.

Abstract
BACKGROUND The identification of implant wear particles and non-implant related particles and the characterization of the inflammatory responses in the periprosthetic neo-synovial membrane, bone, and the synovial-like interface membrane (SLIM) play an important role for the evaluation of clinical outcome, correlation with radiological and implant retrieval studies, and understanding of the biological pathways contributing to implant failures in joint arthroplasty. The purpose of this study is to present a comprehensive histological particle algorithm (HPA) as a practical guide to particle identification at routine light microscopy examination. METHODS The cases used for particle analysis were selected retrospectively from the archives of two institutions and were representative of the implant wear and non-implant related particle spectrum. All particle categories were described according to their size, shape, colour and properties observed at light microscopy, under polarized light, and after histochemical stains when necessary. A unified range of particle size, defined as a measure of length only, is proposed for the wear particles with five classes for polyethylene (PE) particles and four classes for conventional and corrosion metallic particles and ceramic particles. RESULTS All implant wear and non-implant related particles were described and illustrated in detail by category. A particle scoring system for the periprosthetic tissue/SLIM is proposed as follows: 1) Wear particle identification at light microscopy with a two-step analysis at low (× 25, × 40, and × 100) and high magnification (× 200 and × 400); 2) Identification of the predominant wear particle type with size determination; 3) The presence of non-implant related endogenous and/or foreign particles. A guide for a comprehensive pathology report is also provided with sections for macroscopic and microscopic description, and diagnosis. CONCLUSIONS The HPA should be considered a standard for the histological analysis of periprosthetic neo-synovial membrane, bone, and SLIM. It provides a basic, standardized tool for the identification of implant wear and non-implant related particles at routine light microscopy examination and aims at reducing intra-observer and inter-observer variability to provide a common platform for multicentric implant retrieval/radiological/histological studies and valuable data for the risk assessment of implant performance for regional and national implant registries and government agencies.

Abstract
Mild hypothermia reduces the damage caused by hypoxia and oxidative stress, but how this happens is not very clear. Mice were anesthetized and their core body temperature was maintained at 38 ± 0.5°C and 32 ± 0.5°C. The renal artery and renal veins were blocked for 35 minutes and reperfusion was performed. Twenty-four hours later, serum was obtained to detect the concentrations of creatinine. The expression of CIRP, TRX, Bcl-2, and Bax were detected in tissue samples using Western blot. Apoptosis was measured using terminal deoxynucleotidyl transferase-mediated dUTP nick-end labeling and the apoptosis rates were calculated. SOD and MDA were detected to determine the extent of oxidative damage in different groups. The concentration of creatinine in the NC group was 2.11 ± 0.39 mg/dL. Compared to the IR group, the concentration of creatinine decreased in MH+IR group and showed a significant statistical difference (8.74 ± 1.38 mg/dL vs 15.36 ± 2.13 mg/dL, P < .01); the apoptosis rate also decreased with statistical significance (15.02 ± 1.45% vs 37.02 ± 5.70%, P < .01). Compared to the IR group, the expression of CIRP, TRX, and the Bcl-2/Bax ratio significantly increased in the MH+IR group. The SOD activity in the MH+IR group increased (26.90 ± 4.41 U/mgprot vs 16.85 ± 2.41 U/mgprot, P < .05) and the MDA level decreased (0.76 ± 0.18 nmol/mgprot vs 1.37 ± 0.32 nmol/mgprot, P < .05) compared to those of the IR group. Mild hypothermia protects mice kidneys from ischemia-reperfusion damage by reducing oxidative stress injury and apoptosis.

Abstract
Myocardial ischaemia reperfusion injury is the leading cause of death in patients with cardiovascular disease. Interventions such as ischaemic pre and postconditioning protect against myocardial ischaemia reperfusion injury. Certain anaesthesia drugs and opioids can produce the same effects, which led to an initial flurry of excitement given the extensive use of these drugs in surgery. The underlying mechanisms have since been extensively studied in experimental animal models but attempts to translate these findings to clinical settings have resulted in contradictory results. There are a number of reasons for this such as dose response, the intensity of the ischaemic stimulus applied, the duration of ischaemia and lost or diminished cardioprotection in common co-morbidities such as diabetes and senescence. This review focuses on current knowledge regarding myocardial ischaemia reperfusion injury and cardioprotective interventions both in experimental animal studies and in clinical trials.

Abstract
RATIONALE Hemophilic arthropathy (HA) is a crucial morbidity and a major cause of joint pain and disability in patients with hemophilia A. Surgical methods, such as total joint arthroplasty, are of vital importance for end-stage HA treatment, but the feasibility and effects of multi-joint replacement surgery remain debatable. PATIENT CONCERNS A 24-year-old patient with advanced HA presented multiple joint pain. Physical examination revealed joint tenderness, swelling, and limited activity. Radiographs revealed bilateral knee joints and left elbow joint damage with joint space narrowing, articular facet erosion, and bone deformation. DIAGNOSES The patient was diagnosed with hemophilic arthropathy with multi-joint lesions. INTERVENTIONS The key points of this case include arthropathy in multiple joints and the management of simultaneous total multi-joint arthroplasty. We performed bilateral total knee arthroplasty and total left elbow arthroplasty simultaneously after adequate preparations. Special attention was paid to factor VIII infusion, hemorrhage control, and other safety precautions perioperatively. OUTCOMES After the surgery, no complications, such as infection or aseptic loosening, occurred, and the joints functioned well at follow-up. LESSONS The surgical outcome and safety of multi-joint replacement for HA are attested. Simultaneous multi-joint arthroplasty can ameliorate the quality of life for patients with hemophilia A.
