Facial rhytidectomy is one of the most complex and unpredictable procedures in the field of cosmetic and plastic surgery, aiming to rejuvenate the face. The facial rejuvenation surgery began in the early 20th century. The purpose of the surgery is to alleviate the aging characteristics of the skin, fascia, fat and other tissues of the face and neck by surgical means. In China, due to historical development and other factors, it started late. From the late 1980s to the early 1990s, Song Yeguang and other pioneers took the lead in venturing into this field. With the significant growth of the economy and the increasing attention from both medical professionals and marketing to cosmetic surgery, surgeons in this era have made substantial contributions to the systematic and standardized advancement of rhytidectomy surgery. However, with the understanding of the aging process of the face and the in-depth study of the changes in the anatomy and tissue structure of the face and neck, surgical techniques have evolved from simple to complex, and gradually improving over time. Through long-term observation of the surgical outcomes, the surgical technique has evolved from complex to simple. The purpose of this paper is to summarize the evolution of rhytidectomy in China by reviewing the literature from previous years.

Objective:To investigate the clinical outcome of biplanar botulinum toxin type A injection in alleviating platysmal bands.Methods:From November 2022 to May 2023, the clinical data of patients with platysmal bands treated by botulinum toxin type A injection in Department of Face and Neck Plastic Surgery, Plastic Surgery Hospital, Chinese Academy of Medical Sciences, and Department of Plastic Surgery, Chengdu Badachu Cosmetic Hospital were retrospectively analyzed. The platysmal bands were marked, while patients were grinning, before injection. Using a 13 mm 30 G needle, 20 U/ml botulinum toxin was injected into the muscle layer along the bands from the clavicle direction. The dose was 1 U at a single point every 1.5 cm. Using a 3 mm 30 G needle, 10 U/ml botulinum toxin was injected into the deep surface of dermis along the bands with a single point dose of 0.5 U. Effects were evaluated by overall subjective satisfaction of patients, which were categorized into 4 grades: very satisfied, satisfied, dissatisfied, very dissatisfied. In addition, accessment by a third-party physician with global aesthetic improvement scale (GAIS) (1-5 points, the lower the score, the more significant the improvement is) and Geister platysmal band scale (0-4 points, the higher the score, the more severe the platysmal band is). Normal distribution data was represented by Mean±SD.Results:A total of 19 patients were included, including 3 males and 16 females, with the average age of 36.1 years. After a mean follow-up of 1.3 months (1-5 months), the overall subjective satisfaction was 100%(19/19). The GAIS score of third-party physicians was 1.12±0.33. 100%(19/19) of patients received a rating over moderate improvement(significant improvement in 17 cases and moderate improvement in 2 cases). The Geister platysmal band score decreased from preoperative 3.65 ± 0.33 to postoperative 0.76 ± 0.44. No serious complications were found except 5 cases of local congestion and 2 cases of injection pain, which were relieved in 1 week and 3 hours respectively. 2 cases felt mild neck weakness, but neck activity was not affected. The adverse symptoms all completely resolved spontaneously within 4 weeks. All patients have no mouth deviation, difficulty speaking, facial paralysis, allergies, or other noticeable complications.Conclusion:The injection of botulinum toxin type A in dual-plane of platysmal intramuscular layer and deep intradermal layer can effectively alleviate platysmal bands and achieve neck rejuvenation.

Objective:To evaluate the clinical effect of microbotox injection of botulinum toxin type A in improving the fine lines of lower eyelid skin and achieving the rejuvenation of the eye area.Methods:The clinical data of patients with mildly sagging lower eyelid skin and fine wrinkles admitted to Facial and Neck Plastic Surgery, Plastic Surgery Hospital, Chinese Academy of Medical Sciences and Peking Union Medical College; Deparment of Plastic and Cosmetic Surgery, Guangyuan Central Hospital; Department of Dermatology, People’s Hospital of Qingshen County; Department of Plastic and Cosmetic Surgery, Dujiangyan People’s Hospital; Devision of Women’s Healthcare, Panzhihua Maternal and Child Hospital; Chengdu Badachu Cosmetic Hospital from August 2022 to January 2023 were analyzed retrospectively. Using the microbotox injection method, the botulinum toxin type A with a diluted concentration of 8 U/ml was micro-injected into the dermis layer or between the dermis and the superficial muscle layer at an interval of 0.6 cm, and a single point injection of 0.2 U. The injection range was the anatomical distribution range of the orbicularis oculi muscle. After treatment, patients were followed up to investigate patient satisfaction, which was divided into very satisfied, satisfied, dissatisfied and very dissatisfied, and to calculate subjective satisfaction (percentage of the number of very satisfied and satisfied cases in the total number of cases). At the same time, a independent physician used the global aesthetic improvement scale (GAIS) to evaluate the effect based on the patient’s photos before treatment and during follow-up. 5 indicates as worse than before, 4 as no improvement, 3 as were slight improvement, 2 as moderate improvement, and 1 as significant improvement. SPSS 24.0 software was used for descriptive analysis of the data.Results:A total of 23 patients were enrolled, including 1 male and 22 females, aged (36.4±2.5) years old. The follow-up was 1-6 months, with an average of 1.4 months, and the subjective satisfaction of patients was 100% (23/23). The result of the independent physician evaluation were as follows: the overall cosmetic improvement score of the observers was 1.26±0.54, 100% (23/23) of the patients reached the standard of obvious or moderate improvement. In terms of complications, 2 patients presented local epidermis bruises after injection, who recovered within 1 week; 1 patient complained of pain after injection, which was significantly relieved 12 hours later. No ectropion, symblepharon, facial palsy, dry eyes, or other complications were observed.Conclusion:Application of botulinum toxin type A microbotox injection can improve periorbital wrinkles and improve skin texture at the same time, and the therapeutic effect is definite.

The classifications and treatments of tear trough deformity are plenty. Such diverse systems are difficult for patients and plastic surgeons to apprehend. Identificatioins of tear trough are important for accurate diagnosis and direct selection of treatment.The classification of deformity is mostly based on appearance, but barely etiology. It is our belief that the tear trough should be divided into congenital, acquired and aging. The congenital type can be further divided into non age-related type in adolescence and age-related type occurring after 30 years old. And we proposed the treatment strategies based on the classification at the same time. The patients with acquired and severe congenital tear trough should consider surgery. For the rest patients, especially young patients, minimally invasive treatment such as hyaluronic acid and autologous fat filling should be the first choice. With the increase of young people seeking facila rejuvenation, minimally invasive treatment should be addressed, and its complications need to be further investigated and apprehended.

Objective:Our study aims to determine histological regression and clinical improvement after long-term antiviral therapy in hepatitis B virus-related cirrhosis patients.Methods:Treatment-na?ve chronic hepatitis B patients with histologically or clinically diagnosed liver cirrhosis were enrolled. Liver biopsies were performed after 5 years entecavir-based antiviral treatment. Patients were followed up every 6 months. Cirrhosis regression was evaluated based on Metavir system and P-I-R score. Clinical improvement was evaluated before and after the long-term treatment. Kruskal Wallis test and Wilcoxon signed-rank test were used for continuous variables, Fisher's exact test was used for categorical variables and multivariate analysis was performed using logistic regression analysis.Results:Totals of 73 patients with HBV-related liver cirrhosis were enrolled. Among them, 30 (41.1%) patients were biopsy proved liver cirrhosis and the remaining 43 (58.9%) cirrhotic patients were diagnosed by clinical features. Based on Metavir system and P-I-R score, 72.6% (53/73) patients attained histological regression. Furthermore, 30.1% (22/73) were defined as significant regression (Metavir decrease ≥2 stage), 42.5% (31/73) were mild regression (Metavir decrease 1 stage or predominantly regressive by P-I-R system if still cirrhosis after treatment) and 27.4% (20/73) were the non-regression. Compared to levels of clinical characteristics at baseline, HBV DNA, ALT, AST, liver stiffness(decreased from 12.7 to 6.4 kPa in significant regression, from 18.1 to 7.3 kPa in mild regression and from 21.4 to 11.2 kPa in non-regression)and Ishak-HAI score significantly decreased after 5 years of anti-HBV treatment, while serum levels of platelets and albumin improved remarkably ( P<0.05). In multivariate analysis, only the pre-treatment liver stiffness level was associated with significant regression ( OR=0.887, 95% CI: 0.802-0.981, P=0.020). Conclusions:After long-term antiviral therapy, patients with HBV-related cirrhosis are easily to attain improvements in clinical parameters, while a certain percentage of these patients still cannot achieve histological reversal.

Objective:Hepatic amyloidosis is a metabolic disease with a low incidence rate. However, because of its insidious onset, the rate of misdiagnosis is high, and it usually progresses to a late stage when it is diagnosed. This article analyzes the clinical features of hepatic amyloidosis by combining clinical pathology in order to improve the clinical diagnosis rate.Methods:Clinical and pathological data of 11 cases of hepatic amyloidosis diagnosed at the China-Japan Friendship Hospital from 2003 to 2017 were summarized and analyzed retrospectively.Results:The clinical manifestations of 11 cases mainly included abdominal discomfort (4/11), hepatomegaly (7/11), splenomegaly (5/11), fatigue (6/11), etc. Biochemical test results showed that most patients' alanine aminotransferase, aspartate aminotransferase, alkaline phosphatase, γ-glutamyl transferase, total bilirubin, direct bilirubin, and total bile acids, accompanied by hypoalbuminemia were elevated, while some patients' 24-h urinary protein, creatinine, and blood urea nitrogen were elevated.Conclusion:All patients had slightly elevated aspartate transaminase levels (within 5 times the upper limit of normal), and 72% had slightly elevated alanine transaminase. Alkaline phosphatase and γ-glutamyl transferase levels were significantly raised in all cases, with the highest result for γ-glutamyl transferase being 51 times the upper limit of normal. Damage to the hepatocytes has an effect on the biliary system as well, leading to symptoms such as portal hypertension and hypoalbuminemia [(0.54~0.63) × upper limit of normal value, 9/11]. Amyloid deposits within the artery wall (54.5% of patients) and portal vein (36.4% of patients) were also indicative of vascular injury. A liver biopsy should be recommended for patients with unexplained elevated transaminases, bile duct enzymes, and portal hypertension in order to establish a definitive diagnosis.

A liver biopsy has an important suggestive role in the diagnosis of inherited metabolic liver disease (IMLD). This article introduces the IMLD pathological diagnosis considerations, five types of classification of liver biopsy based on the morphological characteristics (basic normal liver tissue morphology, steatosis, cholestatic disease, storage/deposition, and hepatitis), and a summary of the pathological characteristics of different injury patterns and common diseases in order to provide clues for the correct diagnosis.
