Objective:To investigate auricular lobule index difference in healthy young female of different height or weight, and to provide an additional reference for otoplasty of auricular lobule.Methods:Subjects were made up of 266 healthy young females of Henan residents. Their height, weight, physiognomic ear breadth, morphological ear breadth, physiognomic ear length, morphological ear length, auricular lobule length, auricular lobule breadth were measured and calculated. All the data were analyzed by SPSS 15.0 software.Results:We obtained the means, standard deviation of each items, and data were treated statistically. In the 266 subjects, average height was (162.9±4.1) cm, weight (55.3±6.5) kg, morphological ear breadth (4.9±0.6) cm, morphological ear length (2.9±0.3) cm, physiognomic ear breadth (6.2±0.4) cm, physiognomic ear length (3.3±0.3) cm, auricular lobule breadth (1.6±0.3) cm, auricular lobule length (1.8±0.2) cm, lobule physiognomic ear breadth index (25.6±4.9)%, lobule-physiognomic ear length index (53.69±7.69)%, and auricular lobule index (91.4±19.3)%. The differences among the indices mentioned above were of statistical significance ( P<0.05); the indices of subjects of different height were significantly different ( P<0.05); the indices of subjects of different weight were of no statistical difference. ( P>0.05). Conclusions:The subjects of different height or weight have no different morphological ear breadth, morphological ear length, physiognomic ear breadth, physiognomic ear length, auricular lobule length, lobule-physiognomic ear length index and auricular lobule index; hence, the indices are no related to body height and weight. However, the subjects of different height have different auricular lobule breadth and lobule-physiognomic ear breadth index.

Objective:To investigate the clinical characteristics and outcomes in patients with wake-up stroke.Methods:From January 2019 to December 2019, consecutive patients with acute ischemic stroke admitted to the Department of Neurology, Huizhou Municipal Central Hospital were enrolled retrospectively. The modified Rankin Scale was used to evaluate the outcome of patients at 90 d after the onset. 0 to 2 was defined as a good outcome, and >2 was defined as a poor outcome. Multivariate logistic regression analysis was used to determine the factors affecting the poor outcome of patients with wake-up stroke. Results:A total of 356 patients with acute ischemic stroke were enrolled, including 97 (27.2%) wake-up stroke, and 259 (72.8%) non-wake-up stroke. The National Institutes of Health Stroke Scale (NIHSS) score at admission and the proportion of patients with atrial fibrillation, moderate to severe stroke and cardiogenic embolism in the wake-up stroke group were significantly higher than those of the non-wake-up stroke group, and the proportion of patients with small artery occlusion was significantly lower than that in the non-wake-up stroke group (all P<0.05). Moreover, the proportion of patients with poor outcome in the wake-up stroke group was significantly higher than that in the non-wake-up stroke group (36.1% vs. 24.7%; χ2=4.546, P=0.033). In the wake-up stroke group, 62 patients (63.9%) had a good outcome, and 35 (36.1%) had a poor outcome. The NIHSS score at admission and the proportion of patients with atrial fibrillation and moderate to severe stroke in the subgroup with poor outcome were significantly higher than those in the subgroup with good outcome, and the proportion of patients receiving intravenous thrombolysis and mechanical thrombectomy was significantly lower than those in the good outcome subgroup (all P<0.05). Multivariate logistic regression analysis showed that moderate to severe stroke (odds ratio [ OR] 6.674, 95% confidence interval [ CI] 2.223-20.034; P=0.001) was independently associated with the poor outcome in patients with wake-up stroke, while intravenous thrombolysis ( OR 0.102, 95% CI 0.017-0.630; P=0.014) and endovascular mechanical thrombectomy ( OR 0.108, 95% CI 0.023-0.506; P=0.005) were independently associated with the good outcome of patients with wake-up stroke. Conclusions:In patients with wake-up stroke, the proportion of cardioembolism is higher, the clinical symptoms are more serious and the incidence of poor outcome is higher. The severity of stroke at admission is associated with poor short-term outcome, and intravenous thrombolysis and endovascular mechanical thrombectomy can improve the outcome in patients with wake-up stroke.

4.Research Advances in the Application of Adipose-Derived Stem Cells Derived Exosomes in Cutaneous Wound Healing
Annals of Dermatology 2021;33(4):309-317
Cutaneous wound healing has always been an intractable medical problem for both clinicians and researchers, with an urgent need for more efficacious methods to achieve optimal outcomes morphologically and functionally. Stem cells, the body’s rapid response ‘road repair crew,’ being on standby to combat tissue injuries, are an essential part of regenerative medicine. Currently, the use of adipose-derived stem cells (ADSCs), a kind of mesenchymal stem cells with multipotent differentiation and self-renewal capacity, is surging in the field of cutaneous wound healing. ADSCs may exert influences either by releasing paracrine signalling factors or differentiating into mature adipose cells to provide the ‘building blocks’ for engineered tissue. As an important paracrine substance released from ADSCs, exosomes are a kind of extracellular vesicles and carrying various bioactive molecules mediating adjacent or distant intercellular communication.Previous studies have indicated that ADSCs derived exosomes (ADSCs-Exos) promoted skin wound healing by affecting all stages of wound healing, including regulating inflammatory response, promoting proliferation and migration of fibroblasts or keratinocytes, facilitating angiogenesis, and regulating remodeling of extracellular matrix, which have provided new opportunities for understanding how ADSCsExos mediate intercellular communication in pathological processes of the skin and therapeutic strategies for cutaneous wound repair. In this review, we focus on elucidating the role of ADSCs-Exos at various stages of cutaneous wound healing, detailing the latest developments, and presenting some challenges necessary to be addressed in this field, with the expectation of providing a new perspective on how to best utilize this powerful cell-free therapy in the future.

Objective:To explore the resistance of common clinical isolates to chlorhexidine gluconate (CHG) and the clinical characteristics of patients with the infections.Methods:A total of 1 000 isolates from the First Affiliated Hospital of Wenzhou Medical University in 2018 (from January to May) were collected, which included 200 strains each of Escherichia coli ( E. coli), Acinetobacter baumanii ( A. baumanii), Pseudomonas aeruginosa ( P. aeruginosa), Staphylococcus aureus ( S. aureus), and Enterococcus spp.. Minimum inhibitory concentration (MIC) of CHG against 1 000 isolates were determined by the agar dilution method. The correlation between the resistance of isolates and clinical characteristics of infected patients was analyzed. Chi-square test or Fisher exact probability test were used for statistical analysis. Results:A total of 57 CHG resistant strains were detected in 1 000 clinical isolates. These CHG-resistant strains were mainly isolated from sputum and intensive care unit ward, accounting for 49.1%(28/57)and 38.6%(22/57), respectively. The resistance rates of P. aeruginosa, A. baumanii, Enterococcus spp., S. aureus, and E. coli to CHG were 16.0%(32/200), 7.0%(14/200), 3.0%(6/200), 1.5%(3/200) and 1.0%(2/200), respectively. The CHG-resistant rates of P. aeruginosa to ceftazidime, ciprofloxacin, levofloxacin and gentamicin were 53.1%(17/32), 78.1%(25/32), 65.6%(21/32) and 50.0%(16/32), respectively, which were all higher than those of CHG-sensitive P. aeruginosa (25.0%(8/32), 25.0%(8/32), 21.9%(7/32) and 15.6%(5/32), respectively), with statistical significance ( χ2=5.317, 18.080, 12.444 and 8.576, respectively, all P<0.05). The hospital mortality was 22.8%(13/57) in patients infected with CHG-resistant bacteria, which was higher than that in patients infected with CHG-sensitive bacteria ((7.0%(4/57); Fisher exact probability test, P=0.018)). CHG-resistant group had a higher history of CHG exposure and antimicrobial treatment (61.4%(35/57) and 70.2%(40/57), respectively), which were both higher than those with CHG-susceptible isolates (17.5%(10/57) and 47.4%(27/57), respectively), the differences were both statistically significant ( χ2=22.947 and 6.118, respectively, both P<0.05). In addition, the multi-drug resistance rate of CHG-resistant strains was 54.4%(31/57), which was higher than that of CHG-susceptible strains (35.1%(20/57)), the difference was statistically significant ( χ2=4.293, P=0.039). Conclusions:CHG resistant strains have higher antimicrobial resistance. Hospital mortality in patients infected with CHG-resistant bacteria is higher than patients infected with CHG-sensitive bacteria. The important risk factors are CHG exposure and antimicrobial therapy.

Objective:To investigate the association between the polymorphism in a disintegrin and metalloprotease 33 (ADAM 33) gene and keloid in the Chinese Han population from Henan Province. It may provide a new theoretical basis for the prevention and treatment of keloids at the genetic level.Methods:There were 84 patients with keloid and 78 patients with hypertrophic scar in this group.We selected 3 SNPs in ADAM33 gene and detected the sample genotypes by Mass ARRAY system to compare genotype and allele frequency differences at each locus.Results:There were no significant differences in gender and age of two groups ( P>0.05). The genotypes of 3918394 (L1) and rs574174 (ST+ 7) locus in the two groups of ADAM33 gene were consistent with the Hardy-Weinberg genetic equilibrium law ( P>0.05), while the genotypes of rs597980 (ST+ 5) locus in the two groups of ADAM33 gene were not consistent with the Hardy-Weinberg genetic equilibrium law. There was a significant difference of genotypes or alleles in L1 locus between keloid and hypertrophic scar groups ( P<0.05). No significant differences were detected of genotypes or alleles in ST+ 7 locus between two groups ( P>0.05). In addition, there was a significantly difference of GG genotype and G allele between keloid and hypertrophic scar groups ( χ2=6.387、6.117, all P<0.05). There was no significantly difference of all genotypes and alleles in ST+ 7 locus between two groups ( P>0.05). There was weak linkage disequilibrium between ST+ 7 and L1 locus in ADAM33 gene. Haplotype analysis showed that haplotype Hap2 (CA) in keloid group was much lower than hypertrophic scar group ( χ2=6.752, P<0.05). Conclusions:The polymorphism of the L1 locus in the ADAM33 gene may have significant associations with keloid in the Chinese Han population from Henan Province, while the ST+ 7 locus may have no significant associations with that. The GG genotype and G allele of L1 locus is a risk factor for keloids and increases the risk of keloids. The susceptible and protective haplotypes of keloid may exist in Chinese Han population from Henan Province.

Objective:To evaluate the effectiveness of surgical methods for correcting pollybeak deformity in Chinese rhinoplasty.Methods:A retrospective chart review was conducted for patients who underwent pollybeak correction between January 2021 and December 2022 at the Department of Plastic and Aesthetic (Burn) Surgery, the Second Xiangya Hospital of Central South University. Individualized correction was tailored based on the etiology and severity of the nasal deformity of each patient, involving techniques such as resection of the anterior part of the nasal septum, reconstruction of nasal tip support, reconstruction of the middle part of the nasal vault, and excision of skin in the upper region of the nasal tip. A modified classification system for pollybeak deformity, the supratip fullness rating scale (SFRS), was developed to evaluate supratip fullness (0-3 points, with higher scores indicating more apparent deformity). The patients aesthetic outcomes were assessed by surgeons using the visual analogue scale (VAS) (0-10 points, with higher scores indicating more apparent deformity), and patient self-assessed using the rhinoplasty outcome evaluation (ROE) questionnaire (0-100 points, with higher scores indicating higher satisfaction). The measurement data of normal distribution was expressed as Mean±SD and analyzed by paired t-test; the measurement data of non-normal distribution was expressed as M( Q1, Q3) and analyzed by Wilcoxon signed rank test. Results:In a cohort study of 53 rhinoplasty patients (7 male, 46 female; age range 19-45 years, mean 29 years), comprising 15 primary and 38 secondary surgeries, nasal tip deformities were evaluated. Deformities were classified as mild (5 cases), moderate (25 cases), and severe (23 cases). Over a follow-up period of 6-17 months (mean 9.5 months), significant aesthetic improvements in the nasal tip region were observed. The SFRS scores decreased from 2(2, 3) preoperatively to 0(0, 0) postoperatively ( Z = -6.58, P < 0.001), and VAS scores decreased from 7.47±1.73 to 1.79±1.67 ( t = -25.61, P < 0.001). High patient satisfaction was indicated by a mean ROE score of 82.45±11.55. No significant complications, such as nasal tip ptosis, skin necrosis, or scar hyperplasia, were reported. Conclusion:Selecting an appropriate surgical method based on the severity and cause of pollybeak deformity can achieve satisfactory outcomes. Post-operative patients exhibit significant aesthetic improvement in the upper nasal tip area, resulting in high patient satisfaction.

Objective:To investigate the surgical effect of pedicled upper lip mucosal flap in repairing nasal septal mucosal defects after rhinoplasty.Methods:A retrospective analysis was performed from January 2016 to October 2022, the clinical data of patients with nasal septal mucosal defects after rhinoplasty were collected in the Department of Plastic and Aesthetic (Burn) Surgery at the Second Xiangya Hospital of Central South University. The pedicled upper lip mucosal flap was utilized for repair based on the patient’s medical history and wound condition. The pedicle of the flap was designed 1 cm adjacent to the frenulum of the upper lip, and an appropriate flap was incised based on the size of the wound, with dissection performed up to the superficial layer of the orbicularis oris muscle. The dissection establishes an upper lip tunnel that connects the gingival-buccal groove to the nasal cavity. The pedicled upper lip mucosal flap was elevated and transposed into the nasal cavity via the upper lip tunnel. The position of the flap was adjusted to ensure complete coverage and fixation of the nasal septal defect wound using 5-0 absorbable suture. The visual analogue scale (VAS) and the nasal obstruction symptom evaluation (NOSE) scale were utilized to facilitate patients’ satisfaction evaluation and assessment of nasal obstruction symptoms before surgery and at 6 months post-surgery. The VAS total score was 10 points, with higher scores indicating greater levels of patient satisfaction. The NOSE scale comprises of 5 items, each assigned a score ranging from 0 to 4, denoting absence of symptoms, very mild presence, moderate intensity, relatively severe manifestation, and highly severe indication respectively. The measurement data of VAS and NOSE scores before surgery and at 6 months post-surgery was expressed by Mean±SD, using paired t-test. The score distribution of the NOSE scale was represented by the number of cases, using Mann-Whitney U test. Results:The study included a total of 15 female patients, with an average age of (27.6±2.9) years (ranging from 23 to 33 years). Eleven cases presented with preoperative cartilage exposure, and the size of tissue defect ranged from 0.9 cm×0.5 cm to 1.5 cm×0.7 cm. Nine patients had a history of smoking. Skin grafting was performed in 9 patients, while nasal mucosal metastasis was observed in 8 patients. The dimensions of the flap varied from 4.0 cm×1.2 cm to 7.0 cm×1.5 cm. The postoperative recovery was satisfactory, with successful survival of the skin flaps and no occurrences of infection, hematoma, wound dehiscence, or flap necrosis. The average duration of follow-up was (8.2±2.1) months (ranging from 6 to 12 months). The postoperative VAS score (7.73±0.88) was significantly higher compared to the preoperative score (1.86±0.74) ( P<0.01). Additionally, the postoperative NOSE score (4.66±1.71) showed a significant decrease from the preoperative score (10.73±2.68), with a statistically significant difference ( P<0.01). Among them, after surgery items of stuffy or unbreathable nose (2 cases vs. 15 cases), nasal obstruction (1 case vs. 14 cases), and feeling that the nose was not enough to breathe during exercise or exertion (4 cases vs. 14 cases) scored≥2 points were significantly less than those before operation (all P<0.01). Conclusion:The utilization of pedicled upper lip mucosal flap in the reconstruction of severe nasal septal mucosal defects following rhinoplasty has proven to be highly effective. The postoperative satisfaction of patients is remarkably high, the ventilation function exhibits significant improvement, and no severe complications are observed.
