Objective:To introduce a surgical technique of " short distances and multi-segment" buried-guiding suture method and its effects in the surgery of early descent of prosthesis after augmentation mammaplasty.Methods:From August 2019 to January 2022, 15 cases of early descent of prosthesis after augmentation mammaplasty due to axillary approach breast augmentation for micromastia were admitted to the Plastic Surgery Department of Sichuan Provincial People′s Hospital, aged 23-35 years (27.3±3.6) and duration of dislocation from 16 to 35 days (23.8±5.8). There were 12 patients showed unilateral prosthesis drops and 3 patients showed bilateral prosthesis drops. " Short distances and multi-segment" buried-guiding suture method was used to solve the problem, i. e., 2-0 non-absorbable sutures were used to eliminate the lower pole of prosthetic cavity with " short distances and multi-segment" sutures. The distance from the nipple to the midline of the sternum, the distance from the sternotomy to the nipple, the distance from the nipple to the inframammary fold and the distance from the midclavicular point to the inframammary fold were measured bilaterally before and after surgery, and statistical analysis was performed to evaluate the efficacy of the " short distances and multi-segment" buried-guiding suture method for early descent of prosthesis after breast augmentation.Results:All incisions healed by first intention without complications such as hematoma, infection, or scar hyperplasia. 15 patients were followed up for 6-12 months (8.0±1.9). 14 patients were satisfied with the results after surgery, and 1 patient received satisfactory results after secondary surgery. The distance from nipple to inframammary fold was shortened by 0.8-1.4 cm after surgery (1.2±0.2), and the distance from mid-clavicle to inframammary fold was shortened by 1.0-1.6 cm (1.3±0.4), and the differences were statistically significant as compared with the values before surgery ( t=31.17, P<0.05; t=33.78, P<0.05). After surgery, the change in the distance from nipple to sternal was 0.1-0.3 cm (0.16±0.10), and the change in the distance from sternal notch to nipple was 0-0.2 cm (0.12±0.10), and the differences were not statistically significant ( P>0.05). Conclusions:With the advantages of simple operation, little trauma and no additional incision, the " short distance and multi-stage" buried-guiding suture method in the surgery of early descent of prosthesis after augmentation mammaplasty is worthy of clinical application.

Abstract: Objective To understand the mental health literacy level of residents in Hainan Province, and to provide evidence for promoting mental health promotion and improving the mental health literacy level of residents. Methods Multi-stage random sampling method was used to investigate The National Mental Health Literacy Questionnaire among 6 895 residents in 12 districts including Changjiang, Chengmai, Dongfang, Ledong, Lingshui, Haikou Longhua District, Haikou Meilan District, Qionghai, Sanya, Tunchang, Wenchang and Wuzhishan. Results　In the survey 6 895 residents in 12 counties, cities, districts of Hainan Province, 365 of them reached the standard of mental health with the standard rate of 5.3%. The mental health knowledge score was (54.00±17.02) with the standard rate of 7.7%; the self-assessment score was (26.11±3.99) with the standard rate of 75.9%; the score of mental health skill was (26.22±7.25) with the standard rate of 44.8%. The mental health literacy level of medical workers was the highest, with the standard rate of 13.5% (112/830), and the mental health literacy level of farmers was the lowest, with the standard rate of 0.8% (13/1 647). The results of unconditional Logistic regression showed that the factors entering the regression model included educational background (OR=2.268), personal monthly income (OR=1.129), gender (OR=1.302), household registration (OR=0.776), and whether they had participated in mental health related courses OR training (OR=0.511). The higher the educational background and personal monthly income, the higher the psychological quality. The mental health of women was higher than that of men, and that of urban was higher than that of rural, and those who had participated in mental health related courses were higher than those who had not. Conclusions The mental health literacy level of Hainan residents is at a low level, and the influencing factors are multifaceted. It is suggested to strengthen the mental health monitoring comprehensively and carry out rich health education service mode for different groups.

This study aims to provide evidence for clinical practice by systematically reviewing the efficacy and safety of Gusongbao preparation in the treatment of primary osteoporosis(POP). The relevant papers were retrieved from four Chinese academic journal databases and four English academic journal databases(from inception to May 31, 2022). The randomized controlled trial(RCT) of Gusongbao preparation in the treatment of POP was included after screening according to the inclusion and exclusion criteria. The quality of articles was evaluated using risk assessment tools, and the extracted data were subjected to Meta-analysis in RevMan 5.3. A total of 657 articles were retrieved, in which 15 articles were included in this study, which involved 16 RCTs. A total of 3 292 patients(1 071 in the observation group and 2 221 in the control group) were included in this study. In the treatment of POP, Gusongbao preparation+conventional treatment was superior to conventional treatment alone in terms of increasing lumbar spine(L2-L4) bone mineral density(MD=0.03, 95%CI[0.02, 0.04], P<0.000 01) and femoral neck bone mineral density, reducing low back pain(MD=-1.69, 95%CI[-2.46,-0.92], P<0.000 1) and improving clinical efficacy(RR=1.36, 95%CI[1.21, 1.53], P<0.000 01). Gusongbao preparation was comparable to similar Chinese patent medicines in terms of improving clinical efficacy(RR=0.95, 95%CI[0.86, 1.04], P=0.23). Gusongbao preparation was inferior to similar Chinese patent medicines in reducing traditional Chinese medicine syndrome scores(MD=1.08, 95%CI[0.44, 1.71], P=0.000 9) and improving Chinese medicine syndrome efficacy(RR=0.89, 95%CI[0.83, 0.95], P=0.000 4). The incidence of adverse reactions of Gusongbao preparation alone or combined with conventio-nal treatment was comparable to that of similar Chinese patent medicines(RR=0.98, 95%CI[0.57, 1.69], P=0.94) or conventio-nal treatment(RR=0.73, 95%CI[0.38, 1.42], P=0.35), and the adverse reactions were mainly gastrointestinal discomforts. According to the available data, Gusongbao preparation combined with conventional treatment is more effective than conventional treatment alone in increasing lumbar spine(L2-L4) bone mineral density and femoral neck bone mineral density, reducing low back pain, and improving clinical efficacy. The adverse reactions of Gusongbao preparation were mainly gastrointestinal discomforts, which were mild.

Objective:To explore an optimal surgical approach for different types of labia minora hypertrophy and to design a better personalized surgical treatment plan for patients.Methods:From October 2017 to October 2020, 71 patients with labia minora hypertrophy were treated in the plastic surgery department of Sichuan Provincial People＇s Hospital, aged 18-38 years, with an average of 26 years. According to the type and degree of hypertrophy, the appropriate surgical method was selected. The wound healing and complications were observed after operation, and the shape of labia minora was followed up.Results:Among the 71 patients, 1 patient had postoperative hematoma and no flap necrosis after active treatment. 1 patient had poor healing of distal labia minora incision and improved after dressing change. The other patients had good blood supply of labia minora, no necrosis, no postoperative infection, hematoma and other complications. The patients were followed up for 1-6 months. The appearance of labia minora was natural, bilateral symmetry, and the incision scar was hidden. The improvement was significant compared with that before operation. The patients were satisfied with the shape and function.Conclusions:According to the degree of hypertrophy of the labia minora, the specific shape and the psychological expectation of patients, we can choose the appropriate operation method, which can achieve the aesthetic standard of symmetry and beautiful shape of the labia minora, and meet the normal physiological function and aesthetic requirements of patients.

Objective:To discuss the application of free double-layered auriclar composite tissue flap (auriclar cartilage and the skin) in repairing the full-thickness nasal alar defects.Methods:The clinical data of the patients with unilateral full-thickness nasal alar defects who were admitted to the Department of Plastic Surgery of Sichuan Provincial People’s Hospital from June 2016 to December 2019 were analyzed. The free double-layered auricular composite grafts were harvested from the unilateral nasal cavity as the nasal lining and covered with pedicled skin flap. The survival of free double-layered auricular composite grafts and pedicled skin flap as well as the appearance of the reconstructed nasal alar were observed.Results:A total of 12 patients with unilateral full-thickness alar defect were included, including 4 females and 8 males, aged from 6 to 53 years old, with an average of 35.3 years old. The areas of the defects were 0.7 cm × 1.0 cm-2.0 cm × 2.6 cm, and the areas of double-layered auricular composite grafts(skin) were 0.8 cm × 1.0 cm-2.1 cm × 2.7 cm. All the 12 patients healed primarily. No necrosis or infection occurred in the double auricle composite tissue flap and pedicled skin flap. After the completion of the whole treatment, the reconstructed nasal alar with similar shape and function to the normal nasal alar was obtained. After the last operation, the patients were followed up for 3 months to 32 months, with an average of 15 months.Conclusions:The free double-layered auricular composite grafts breaks the area limitation of free transplantation of full-layer auricle composite tissue flap. The combined grafting with pedicled flap shortens the treatment duration with skin flap alone, and it is easier to obtain vivid nasal alar.

The aim of this study was to investigate the effects of polarization program on the ability of macrophages to regulate iron metabolism. M1 and M2 macrophages were propagated in vitro from porcine alveolar macrophages 3D4/2 and polarized by cytokines. The 3D4/2 macrophages were treated with 20 ng/mL interferon gamma (IFN-γ) and 10 ng/mL interleukin-4 (IL-4) combined with 10 ng/mL macrophage colony-stimulating factor (M-CSF) to induce polarization to M1 and M2, respectively. After incubation for 24 h, the expression levels of inflammatory factors and iron-metabolism genes were determined using real-time qPCR, Western bot and immunofluorescence. The M1/M2 macrophages culture media supernatant was collected and used to treat porcine intestinal epithelial cells IPEC-J2. The proliferation ability of IPEC-J2 was detected using CCK-8 assay kit. Following exogenous addition of ammonium ferric citrate (FAC) to M1/M2 macrophages, the phagocytic function of macrophages was detected using fluorescein isothiocyanate-dextran (FITC-dextran) and flow cytometry. The results showed that, compared with control, M1 macrophages had higher mRNA levels of iron storage proteins (ferritin heavy and light polypeptide, i.e. FtH and FtL), hepcidin and lipocalin-2, as well as iron content. Moreover, iron enhanced the ability of M1 macrophages to phagocytize FITC-dextran. There was no significant change in these mRNA expression levels in M2 macrophages, but the mRNA expression levels of ferroportin and transferrin receptor were up-regulated. In addition, the conditioned media supernatant from M2 macrophages promoted cell proliferation of IPEC-J2. These findings indicate that M1 macrophages tend to lock iron in the cell and reduce extracellular iron content, thereby inhibiting the proliferation of extracellular bacteria. While M2 macrophages tend to excrete iron, which contributes to the proliferation of surrounding cells and thus promotes tissue repair.
