Objective: To analyze the differences between adults and children in the epidemic characteristics and clinical manifestations of chickenpox and provide a reference for the prevention strategy adjustment of chickenpox. Methods: The incidence data of chickenpox surveillance in Shandong Province from January 2019 to December 2021 were collected. Descriptive epidemiological methods were used to analyze the distribution of cases, and the chi-square test was used to compare the differences in epidemiological characteristics and clinical manifestations of varicella cases between adults and children. Results: A total of 66 182 cases of chickenpox were reported from 2019 to 2021, including 24 085 cases of adults chickenpox, the male to female sex ratio was 1∶1 (12 032∶12 053), basically the same for men and women, and 42 097 cases of children chickenpox, with a gender ratio of 1.4∶1, the male to female ratio was 1.4∶1 (24 699∶17 398). Fever in chickenpox cases was mainly low and moderate, but the proportion of moderate fever with temperature between 38.1 and 39.0 ℃ in children cases (35.0%,14 744/42 097) was significantly higher than that in adults (32.0%,7 696/24 085). The number of herpes in chickenpox cases was mainly less than 50, but the proportion of severe cases with 100-200 herpes in children was higher than that in adults. The incidence rate of complications was 1.4% (333/24 085) in adults chickenpox, the incidence rate of complications was 1.7% (731/42 097) in children chickenpox. The incidence of encephalitis and pneumonia in children was higher than in adults, and the difference was statistically significant (P<0.05). The proportion of chickenpox cases was mainly outpatient, but the hospitalization rate of children cases was 14.4% (6 049/42 097), higher than that of adults, which was 10.7% (2 585/24 085). Conclusions: There were differences between adult chickenpox and child chickenpox in terms of epidemic and clinical manifestations; the symptoms of child chickenpox were more serious than adult chickenpox. However, the adult chickenpox population is generally susceptible and lacks immune strategy protection, which calls for more attention.

Objective: To investigate and understand the medical security and quality of life of migrant workers with pneumoconiosis, so as to provide scientific basis for the prevention and control countermeasures of migrant workers with pneumoconiosis and targeted poverty alleviation. Methods: Using a stratified random sampling method, 200 migrant workers diagnosed with pneumoconiosis at the Shandong Academy of Occupational Health and Occupational Medicine from January 2016 to December 2021 were selected as the observation group, while 200 non migrant workers diagnosed with pneumoconiosis were selected as the control group. St. George's Respiratory Questionnaire (SGRQ) and Pneumoconiosis Questionnaire were used to collect and compare information on the age, working age of dust exposure, economic sources, employment status, income, medical security and quality of life of two groups of patients. Results: The age of migrant worker pneumoconiosis patients in the observation group was (58.1±8.1) years old, and the working age of dust exposure was (19.3±10.1) years. The main source of income was children support (85.5%, 171/200), employment status was mainly wait for employment or unemployed (69.0%, 138/200), personal monthly income was mainly non income (90.0%, 180/200), and family annual income was mainly less than 10000 yuan (48.0%, 96/200). The average personal annual medical expenditure of 5000-<10000 yuan accounted for 42.0% (84/200). The age of pneumoconiosis patients in the control group was (59.2±8.9) years old, and the working age of dust exposure was (20.2±10.5) years. The main source of income was retirement pension or salary (99.0%, 198/200), with retirement as the main employment status (66.0%, 132/200), the main personal monthly income was 2000-<4000 yuan (61.5%, 123/200), the main family annual income was 20000-<40000 yuan (44.0%, 88/200), and the average personal annual medical expenditure was mostly non-expenditure (92.0%, 184/200). There were statistically significant differences in the distribution of economic sources, employment status, personal monthly income, family annual income and average personal annual medical expenditure between the two groups (P<0.001). The main type of insurance for the observation group was rural cooperative medical care (68.5%, 137/200), and 87.0% (174/200) had no medical reimbursement and a proportion less than 50%. There were statistically significant differences in insurance type and medical reimbursement proportion between the two groups (P<0.001). The respiratory symptoms, activity ability, daily life influence and total quality of life scores of pneumoconiosis patients in the observation group were significantly higher than those in the control group, the differences were statistically significant (P<0.001) . Conclusion: Migrant workers with pneumoconiosis have low income, high medical expenditure, low medical reimbursement proportion and poor quality of life. Therefore, it is necessary to draw high attention from relevant departments and provide timely attention and assistance to improve the quality of life of migrant workers with pneumoconiosis.

ObjectiveTo observe the effect of asiaticoside (AC) on the expression of T helper 17 (Th17) cells and regulatory T (Treg) cells in DBA/1 mice with collagen-induced arthritis (CIA). MethodMale SPF DBA/1 mice were randomized into six groups according to body weight: control group, CIA group, methotrexate group (MTX group, ip, 0.5 mg·kg-1), and AC low-, medium-, and high-dose groups (ig, 5, 15, 45 mg·kg-1, respectively). Modeling was performed in rats other than the control group. To be specific, they were immunized with bovine type Ⅱ collagen and complete Freund's adjuvant on the first day and with bovine type Ⅱ collagen and incomplete Freund's adjuvant on the 21st day. Administration began on the day of the second immunization, once a day for 28 days. On the 49th day, related tissues were collected. Then, hematoxylin-eosin (HE) staining was performed to observe the pathological changes of the joints. Immunohistochemical method was used to detect the expression of interleukin-17 (IL-17) and forkhead box protein-3 (FoxP3), the markers of Th17 and Treg cells, respectively, immunofluorescence double staining the expression of IL-17 and FoxP3 in CD4+T cells of mouse joint tissue, and flow cytometry the proportions of Th17 and Treg cells in mouse lymph nodes. ResultCompared with the control group, CIA group demonstrated joint disorder, damage of articular cartilage and bone, severe bone erosion (P<0.01), increase in stained CD4 and IL-17 and the integral absorbance (IA) (P<0.01), decrease in stained FoxP3 and the IA (P<0.01), rise of Th17/Treg ratio (P<0.01), elevation of Th17 expression in mouse lymph nodes (P<0.01), and reduction in Treg expression (P<0.01). Compared with CIA group, MTX group and three AC groups showed normal joints, alleviated bone erosion and damage, intact and smooth joint surface, and decrease in stained IL-17 and IA (P<0.05, P<0.01), and MTX group and AC medium-dose and high-dose groups registered decrease in stained CD4 and IA (P<0.01) and reduction in Th17/Treg ratio (P<0.05, P<0.01). Moreover, AC medium-dose and high-dose groups showed rise in stained FoxP3 and IA (P<0.05, P<0.01). In the lymph nodes of mice, decrease in expression of Th17 cells (P<0.05, P<0.01) and the increase in expression of Treg cells (P<0.05, P<0.01) were observed in all the three AC group. ConclusionAC can regulate Th17/Treg balance by inhibiting the expression of Th17 cells and promoting the expression of Treg cells in CIA mice.

Objective:To observe the effect of Fangji Huangqitang (FJHQT) on collagen induced arthritis (CIA) and synovial angiogenesis in DBA/1 mice. Method:DBA/1 mice were randomly divided into normal group, CIA group and FJHQT group. DBA/1 mice in CIA group and FJHQT group were immunized with bovine type Ⅱ collagen and complete Freund's adjuvant on the first day, and DBA/1 mice were immunized with bovine type Ⅱ collagen and incomplete Freund's adjuvant on the 21<sup>st</sup> day to establish CIA model. On the day of the second immunization, the drug was given by gavage once a day for 28 days. On the 22<sup>nd</sup> day, the arthritis score and other symptoms of CIA mice were observed. On the 49<sup>th</sup> day, Hematoxylin eosin (HE) staining was carried out to observe the angiogenesis in the synovium of CIA mice, the expression of vascular endothelial cell marker platelet endothelial cell adhesion molecule-1 (CD31) and vascular endothelial growth factor (VEGF) in the synovium of CIA mice were detected. Immunofluorescence double staining was used to detect the mature and immature vessels in the synovium of CIA mice. And the microvascular growth of the rat thoracic aortic ring was induced by VEGF (20 μg·L<sup>-1</sup>). The effects of FJHQT (0.25, 0.5, 1 g·L<sup>-1</sup>) at different concentrations were observed under microscope. Result:Compared with the normal group, the inflammation, joints, red and swelling of the inflammatory joints of the CIA group were significantly increased (<italic>P</italic><0.01). The scores of clinical arthritis, the incidence rate, synovial inflammation and angiogenesis were significantly increased (<italic>P</italic><0.01). The density of blood vessels, the positive expression of CD31 and VEGF, the number of immature vessels in synovial membrane were significantly increased (<italic>P</italic><0.01). And compared with the CIA group, the inflammation, joint swelling, and malformation of the FJHQT group were significantly improved, the clinical arthritis score, incidence rate, synovial inflammation and angiogenesis were significantly reduced (<italic>P</italic><0.01). The vascular density, the positive expression of CD31 and VEGF, and the number of immature blood vessels in synovial membrane were significantly increased (<italic>P</italic><0.01). Compared with blank group, VEGF could significantly induce the growth of microvasculature in rat thoracic aortic ring (<italic>P</italic><0.01). Compared with VEGF group, FJHQT(0.25, 0.5, 1 g·L<sup>-1</sup>) could significantly inhibit the formation of microvasculature in rat thoracic aortic ring (<italic>P</italic><0.01).

BACKGROUND@#Autologous fat grafting has gained popularity in breast augmentation. Various methods can be used to estimate the volume retention rate. This systematic review aimed to establish whether the type of method used for measuring breast volume is a factor that influences the reported volume retention rate.@*METHODS@#Studies were identified using the electronic databases PubMed, Embase, Cochrane Central Register of Controlled Trials, and Web of Science from inception of the database up to February 2019. Articles describing autologous fat grafting for breast augmentation were selected based on pre-determined inclusion and exclusion criteria. The characteristics of the included studies were summarized, and the reported volume retention rate from the studies was compared. A quality assessment of all included articles was performed using the methodological index for non-randomized studies criteria.@*RESULTS@#A total of 618 articles were identified, of which 12 studies, with a total of 1337 cases, were eligible. The retention rate of injected adipose tissue varied when the method of fat grafting and volume analysis used were both the same, as well as when the method of fat grafting was the same but the method of volumetric evaluation used was different.@*CONCLUSIONS@#Currently, the tools available for estimating the volume retention rate come with limitations. In order to objectively evaluate the percentage of graft retention, a standard protocol that applies to the different methods should be established in the future.

Résumé
There still remains a great amount of details in many aspects of mammaplasty and breast reconstruction. To meet personal requirements of different individuals, it is necessary to continuously explore and master new techniques, while constantly refining aesthetic and technical standards. In recent years, great technical progress has been made in mammaplasty and breast reconstruction in China. Here we published several domestic representative frontier studies in current issue: (1)Through investigation and comparative study of breast reconstruction patients by using BREAST-Q scale, it was found that the indexes were significantly higher in patients who underwent breast reconstruction than those who did not, while the satisfaction with the abdominal function considerably decreased in patients of breast reconstruction with abdominal flaps. (2)As a remarkable supplement to domestic breast reconstruction technique, applying transverse upper gracilis flap(TUG) could be well-indicated for patients with less skin defects and smaller unaffected breast, and for bilateral simultaneous breasts reconstruction. (3)Breast reconstruction with simultaneous implant placement and autologous fat granules grafting after tissue expansion can solve the problem of insufficient coverage on implant resulted from tissue expansion, and therefore provide better palpability, appearance and symmetry of reconstructed breasts. (4) The new method of positioning the nipple in reduction mammaplasty for different degrees of breast hypertrophy is of great practical value to asymmetrical hypermastia and contralateral breast reduction operation following unilateral breast reconstruction.The academic literature on mammaplasty and breast reconstruction published in this issue highlights the domestic developments in this domain in recent years. It represents the trend in refining and individualizing breast reconstruction, indicating a new era of precise and personalized mammaplasty and breast reconstruction has arrived.
Résumé
Objective@#To investigate the satisfaction and well-being of Chinese women with breast deficiency, and to analyze the relevant influencing factors.@*Methods@#A cross-sectional study was conducted using a self-designed questionnaire to investigate the women with breast deficiency, visiting the Plastic Surgery Hospital of Chinese Academy of Medical Sciences from November 2013 to August 2018. The BREAST-Q BR (breast reconstruction) pre-operation and post-operation modules were used to assess the quality of life.@*Results@#A total of 139 effective questionnaires were collected, including 83 patients before BR surgery and 56 post. There was no difference in quality of life in different ages, marital status, education levels, working status, and causes of breast deficiency. Mean scores of satisfaction with breasts, psychosocial well-being and sexual well-being of patients after breast reconstruction were significantly higher than those of patients without reconstruction (P=0.000), but there was no statistical difference in physical well-being-chest score. The physical well-being abdomen scores of patients with abdominal flap reconstruction was lower than that of the patients without reconstruction (P=0.007). With regard to analysis of specific items, compared with preoperative patients, patients with abdominal flap reconstruction reported lower scores in the items related to abdominal muscle weakness (P<0.05).@*Conclusions@#The breast deficiency resulting from Poland syndrome, breast cancer and other causes, can lead to a significant decrease in quality of life. Breast reconstruction can improve satisfaction with breast, psychosocial and sexual well-being in women with breast deficiency. The abdomen well-being of patients with abdominal flap reconstruction is decreased. Therefore, more attention should be paid to retain abdominal muscles to maintain abdominal shape and motor function during operation.
Résumé
Objective@#This is a study to evaluate complication rate, satisfaction and quality of life after breast reconstruction under different classifications. The classification criteria are the timing of operation, surgical procedures, and patients′age.@*Methods@#By reviewing the surgical cases from August 2004 to June 2018, the authors summarized the data of 102 patients with breast reconstruction of the same surgeon in Peking University People′s Hospital and Plastic Surgery Hospital (Institute) CAMS PUMC. Fifty-four patients who met the inclusion criteria and completed the BREAST-Q breast reconstruction module scale, were divided into immediate group or delayed group, according to the timing of operation; divided into abdomen group or other procedures group, according to the surgical procedure; and divided into the young patients′group or senior patients′group according to age. The index were (1) postoperative complication rate, (2)satisfaction with breasts, psychosocial well-being, physical well-being of chest and abdomen, sexual well-being, satisfaction with outcome, satisfaction with information, satisfaction with care (based on the BREAST-Q scale).@*Results@#Complication rate was 9.1%(1/11) in the immediate group, 16.3%(7/43) in the delayed group, 14.7%(5/34) in the abdomen group, 15.0%(3/20) in other procedures group, 13.6%(3/22) in the young patients′group, and 15.6%(5/32) in the senior patients′group. There was no significant difference in the incidence of complications (P>0.05). The postoperative scores of satisfaction with breasts, psychological well-being and sexual well-being were significantly higher in the immediate group than in the delayed group(P=0.026, P<0.001 and P=0.001, respectively). The score of postoperative physical well-being of chest was significantly higher in the abdomen group than other procedures group(P=0.020). The score physical well-being of abdomen was lower compared with the preoperative in the abdomen group (P<0.001). The score of physical well-being of abdomen was lower in the senior patients′group than that of the young patients′group (P=0.010).@*Conclusions@#The complication incidence of breast reconstruction patients was similar among different groups. The breast reconstruction surgery can significantly improve satisfaction and quality of life of patients. To some extent, immediate breast reconstruction can reduce the psychological and physiological effects of breast loss on patients, leading to higher postoperative satisfaction. Breast reconstruction with abdominal flaps can provide patients with better chest health but poor abdomen health. Although elderly patients undergoing breast reconstruction will have poor physical well-being of abdomen, they can still achieve higher satisfaction of operation.
Résumé
Fat regeneration plays an important role in maintaining fat volume after transplantation, and preadipocyte is the primary source of fat regeneration. Inflammatory microenvironment plays an important role in regulating fat regeneration. As a key role in this process, the effect of macrophages on preadipocytes is a research hotspot. In this paper, we summarized the previous studies in related fields at home and abroad, and made a briefly review of the effects of macrophages on adipogenesis, proliferation and survival of preadipocytes.

Résumé
Due to the limited surgical variety, laggard surgical approaches and the unpopularity of breast reconstruction, domestic techniques on breast reconstructive and plastic surgery was relatively backward internationally. Recently, it has made enormous progress generally on the following six aspects: ①The awareness on breast reconstruction has been fully advocated and popularized; ②Breast reconstructive techniques have been creatively applied; ③Breakthrough has been made on simplex fat grafting based breast reconstruction; ④The improvement on surgical accuracy and security has been acquired via the application of imaging technologies, such as CTA and ICG; ⑤Three dimensional (3D) technique has been applied on the whole breast plastic surgical process from the pre-operative design to the post-operative follow-ups; ⑥Distinctive and advanced system of implant-based breast augmentation has formed in China. Articles in this column could be regarded as the epitome of recent developments on breast reconstructive and plastic surgery. Looking forward to more relevant innovative achievements and findings with Chinese characteristics in the future.
Résumé
Objective@#To investigate the application and therapeutic effect of external tissue expansion-assisted autologous fat grafting for delayed breast reconstruction.@*Methods@#Patients began wearing the BRAVA negative pressure system 8 hours a day for recipient tissue expansion for one month before the fat grafting procedure. After fat grafting, BRAVA was recommended to be worn 8 hours a day from postoperative 48 hours to one month. The interval of each fat grafting procedure was 2.5 to 3.0 months. The procedures were repeated until the completion of breast reconstruction. Water-jet assisted liposuction and subcutaneous release of scars were also performed during surgery.@*Results@#From January 2013 to November 2016, 29 patients were followed up for 12 to 58 months, with average of 31.6 months. 28 patients completed the external tissue expansion-assisted autologous fat grafting breast reconstruction. Completion required 1 to 6 procedures, with average of 3.4 procedures. The total initial fat fill volume for each breast was ranged from 200 to 1 000 ml, with average of 583.7 ml. The initial fat fill volume for each breast was ranged from 92.5 to 243.7 ml per operation, with average of 173.8 ml. One patient underwent latissimus dorsi myocutaneous flap breast reconstruction after 3 fat grafting procedures. 8 patients completed the inframammary fold reconstruction, 3 patients underwent breast lift, 1 patient underwent lipofilling augmentation for the contralateral side. Postoperative satisfaction rate was 82.8% in patients and 75.9% in surgeon. Complication statistics: 5 cases of palpable nodules which recognized as fat necrosis (17.2%), one case of nontuberculous mycobacterial infection (3.4%) and one case of locoregional cancer recurrence (3.4%).@*Conclusions@#External tissue expansion-assisted autologous fat grafting is a minimally invasive procedure for breast reconstruction. Satisfactory results could be obtained for most of the patients who would like to choose fat grafting and have enough fat deposit in other parts of the body.

Objective@#To compare the scar condition after breast implantation with axillary, periareolar and inframammary fold (IMF) incisions.@*Methods@#The consecutive patients who were diagnosed as breast hypoplasia and underwent breast implantation surgeries between May 2012 to December 2014 were included in the research. The scars were assessed at 1, 6 and 12 months after surgery with VSS and patient satisfaction scoring. The results were analyzed with Variance and Kruskal-Wallis test based on the data type.@*Results@#The scars of 173 patients were assessed 3 times with the follow-up rate being 82.4%. The VSS scores of every incision declined with time, and the patient satisfaction scores increased gradually. At one month after surgery, the media VSS scores were 6 in axillary group and 4 in periareolar and IMF groups, the differences had statistical significance (P<0.05). The media scores of patients satisfaction were 8 in periareolar group and 7 in axillary and IMF groups. The scores of periareola group were higher than those of axillary with statistical significance(P<0.05). When 6 months after surgery, the media VSS scores were 4 in axillary group and 3 in periareolar and IMF groups. The scores of axillary group were higher than those of IMF with statistical significance(P<0.05). The media scores of patients satisfaction were 8 in 3 groups. When 12 months after surgery, the media VSS scores were 0.5 and 1 in periareolar group (left and right respectively), and 2 in axillary and IMF groups. The media scores of patients satisfaction were 9 in 3 groups. No differences were found in VSS and patients satisfaction scores among three kinds of incisions (P>0.05).@*Conclusions@#The scars of three incisions achieved similar cosmetic effects and patient satisfaction at long-time follow-up.
Résumé
In recent years, breast implant-associated anaplastic large cell lymphoma (BIA-ALCL) has become the research focus of many specialists in the field. This study introduces the epidemiological features of BIA-ALCL, reviewing the characteristics of prosthesis implantation and prosthesis and briefly describing its clinical manifestations, diagnosis, and treatment. Additionally, the research progress of its disease mechanism was summarized. Altogether, BIA-ALCL not only requires plastic surgeons to be vigilant and to regulate the collection and reporting of cases, but also requires them to use a multidisciplinary approach for conducting thorough research.
