Endometriosis （EMT） is a common disease with frequent occurrence and difficult to be cured in modern clinical practice of obstetrics and gynaecology. It is characterized by progressively worsening dysmenorrhoea， pelvic mass， and infertility. The incidence of EMT is growing and increasingly younger patients are diagnosed with this disease， which poses a serious threat to the reproductive and psychological health of women of childbearing age and adolescent females. However， the pathogenesis of EMT is still not completely clear， and the disease has a long course. Therefore， developing new therapies is an urgent clinical problem to be solved. Great progress has been achieved in the treatment of EMT with traditional Chinese medicine （TCM）， while the underlying mechanism remains in exploration. Programmed cell death （PCD） is a cell death mode mediated by a variety of bio-molecules with specific signaling cascades. The known PCD processes include apoptosis， pyroptosis， autophagy， ferroptosis， and cuproptosis， which all play a pivotal role in the development of EMT. Researchers have made achievements in the treatment of EMT with TCM， which regulates PCD via multiple pathways， routes， targets， and mechanisms. However， the progress in the regulation of PCD in the treatment of EMT with TCM remains to be reviewed. This paper reviews the research progress in the treatment of EMT with TCM from five PCD processes （apoptosis， pyroptosis， autophagy， ferroptosis， and cuproptosis）， with the aim of providing a theoretical basis for the clinical prevention and treatment of EMT.

Artificial intelligence (AI) has been widely used in all walks of life, including healthcare, and has shown great application value in the auxiliary diagnosis of pulmonary nodules in the medical field. In the face of a large amount of lung imaging data, clinicians use AI tools to identify lesions more quickly and accurately, improving work efficiency, but there are still many problems in this field, such as the high false positive rate of recognition, and the difficulty in identifying special types of nodules. Researchers and clinicians are actively developing and using AI tools to promote their continuous evolution and make them better serve human health. This article reviews the clinical application and research progress of AI-assisted diagnosis of pulmonary nodules.

Objective: To investigate the association between ABO blood-group system and congenital microtia. Methods: Patients with congenital microtia treated in the Plastic Surgery Hospital of the Chinese Academy of Medical Sciences from January 1, 2017 to February 28, 2019 were collected as the case group. Non-malformed patients admitted to the same hospital from January 1, 2017 to February 28, 2019 were collected as the control group. ABO blood group was determined by tube agglutination test. The distribution of ABO blood group in both group was counted and Chi-square test was used for statistical analysis with a significance level α=0.05. Then spilt chi-square test was applied to compare the difference between blood groups using Bonferroni correction for multiple comparisons (significance level α′=0.008 3) if a statistically significant difference was found in chi-square test. Odds ratio (OR) and its 95% confidence intervals (CI) were calculated to compare the association between ABO blood group and risk of microtia by using Woolf’s method . All statistical analysis was performed with SPSS version 25.0. Results: 2 317 patients with congenital microtia (case group) and 5 411 patients without malformation (control group) were included in this study. The distribution of ABO blood types in congenital microtia group was 29.39% (681/2 317) for type A, 31.89% (739/2 317) for type B, 9.75% (226/2 317) for type AB, and 28.97% (671/2 317) for type O. The distribution of blood group was B>A>O>AB. While, the distribution of blood groups in the control group was O>B>A>AB, which was statistically different from the congenital microtia group (χ²=8.387, P=0.039). The incidence of congenital microtia differed significantly between A blood group and O blood group (χ²=7.448, P=0.006). The risk of congenital microtia was significantly lower in blood group O (OR=0.863, 95% CI: 0.776-0.960, P=0.007) and relatively higher in blood group A (OR=1.110, 95% CI: 0.997-1.236). Conclusions In the population managed in the Plastic Surgery Hospital of the Chinese Academy of Medical Sciences, ABO blood group is correlated with the occurrence of congenital microtia. O blood group is a potential protective factor. While A blood group is susceptible to congenital microtia.

Objective: To describe the general and histological features of the full-length superficial fascia of the circumferential upper limb. Methods: Fresh frozen arm specimens were dissected, and then MRI imaging in vivo, enhanced CT angiography and HE histological staining were used to describe the characteristics of the full-length superficial fascia of the circumferential arm and its relationship with important blood vessels. Results: The four typical structures of the superficial fascia of the arm were divided into subcutaneous superficial fat, membrane-like substance, deep fat and deep fascia from superficial to deep. The thickness and stratification, fusion degree and histological characteristics of the superficial fascia of these four layers were obviously different in different levels and regions of the arm. MRI confirmed that the total thickness of superficial fascia gradually decreased from shoulder to wrist. Venography showed that the cephalic vein ran below the second layer of superficial fascia and above the deep fascia. The basilic vein originated from the dorsal vein network of the hand and always lied below the second layer of membranous material until the basilic vein penetrates below the deep fascia of the upper arm. Conclusions The deep understanding of the circumferential full-length of superficial fascia structure of the upper limb provides an important theoretical basis for improving the surgical safety and fine operation for the Dynamic Arm Circumferential Liposuction.

Objective: To describe an extended whole upper limb liposuction technique and evaluate its clinical effect. Methods: 34 patients who underwent upper limb liposuction from February 2018 to February 2019 were selected and the clinical data were retrospectively summarized. Patients were treated with upper arm ring/upper arm ring + forearm 1/3 rings/whole arm ring aspiration combined with accessory mammary gland, armpit, scapula and other adjacent aesthetic parts of extended liposuction. The preoperative and postoperative maximum circumference, thickness of the anterior and posterior subcutaneous tissue and skin laxity were measured and compared. analysis of complications, and evaluation of patients′ satisfaction through satisfaction questionnaire. Results: The arm shape of all patients was significantly improved, the maximum circumference of the arm was reduced (16.2±4.0)%, the distance of the upper arm was reduced (29.5±8.9)%, the thickness of the posterior subcutaneous tissue was reduced (56.6 ±6.2)%, and the thickness of the anterior subcutaneous tissue was reduced (44.7±9.6)%. There were three cases of mild anemia after operation, and no other serious complications occurred. Patient satisfaction was very high. Conclusions This is an innovative arm liposuction technique with hidden incision. The effect of improvement is remarkable. The patient′s satisfaction is high.

Objective: To investigate the clinical efficacy and safety profile of hyaluronic acid dermal filler(Restylane®) in treating nasolabial folds in Chinese population. Methods: 103 subjects in this study were recruited from five Chinese clinical trial centers between July 2014 and December 2015. Subjects were treated with hyaluronic acid dermal filler in correcting nasolabial folds and an optional re-treatment was performed after 12 months according to the subjects′wishes. The improved of nasolabial folds was evaluated by the change of severity (wrinkle severity rating scale, WSRS) and aesthetic improvement (global aesthetic improvement scale, GAIS). Satisfaction of subjects on treatment was evaluated using subject satisfaction questionnaires (SSQ). Safety indicators such as pain, skin and soft tissue presentation at the injection site were continuously evaluated throughout the whole treatment process. Results: Significant improvement in scores of WSRS and GAIS of all subjects was observed after treatment. Nine months after treatment, the scores of WSRS in 80 subjects (77.7%) and GAIS in 96 subjects (93.2%) were still improved. The 68 subjects (95.8%) received re-treatment after 12 months gained further improvement in nasolabial folds. Most adverse events were mild or moderate (transient/reversible local manifestations) and all resolved before study end, no severe adverse event related to products observed. Conclusions Hyaluronic acid dermal filler is effective and safe in treatment of nasolabial folds in Chinese population and the effect can last up to 12 months.

Objective: To explore the application of the 3D precise digital technology in restoring structural defects of the orbital region. Methods: Structural defects of the orbital region concerning on osseous structure and soft tissue were restored in one stage or stages using EH composite artificial bone prosthesis with complex three-dimensional structure. The fabrication of EH composite artificial bone prosthesis was based on CT scanning and 3D reconstruction of the skull with computer aided data analysis and design. The appearance, degree of satisfaction and the complications were evaluated in postoperative regular follow-up. Results: Five cases of structural defects in the orbital regions presenting bone defect and soft tissue abnormality, received treatments in the department from January 2016 to September 2017. The cases consist of one patient with dysplasia following surgical treatment, three with post-traumatic and one with Treacher-Collins syndrome. With the application of individualized EH composite artificial bone fabricated by aforementioned method, all the repair materials presented the ideal three-dimensional structure and coincided well with the defects, and soft tissue restoration of 2 cases was performed in one stage or by stages. Appearance and symmetry of the 5 cases was significantly improved, without complications of infection, rejection, exposure or graft tissue necrosis. All the patients were satisfied with the results. Conclusions In consideration of the capacity to fabricate accurate individualized repair materials, the three-dimensional digital technology plays an important role in the treatment of structural defects in the orbital region, especially the reconstruction of the bony contour. The simple orbital deformities can be treated with the repair materials and correction of soft tissue. For special orbital deformities, attention should be paid to bone structure repair, eye socket reconstruction and filling of orbital contents sequentially.

Objective: The purpose of this study was to explore the surgery-first approach in sequential combined orthodontic-orthognathic treatment to shorten total treatment duration and improve the clinical outcome. Methods: This study included 185 patients with Angle classⅢ malocclusion. The patients were divided into 3 different types according to cephalometry analyses and facial features. ①Type Ⅰ: mandibular prognathism or asymmetry mandibular prognathism; ②Type Ⅱ: mandibular prognathism and maxillary retrusion; ③ Type Ⅲ: mild Angle′s Class Ⅲ malocclusion, cross bite in anterior teeth, or normal overlap and overbite relation with midfacial hypoplasia. All of patients received surgery first approach therapy. The surgical procedures were chosen according to different malformation types. Type Ⅰ was treated with the sagittal split ramus osteotomy (SSRO). Type Ⅱ was treated by Le Fort Ⅰmaxillary osteotomy combined with SSRO. Type Ⅲ underwent anterior subapical osteotomy combined pyriform aperture augmentation with biomaterials as well as maxillary anterior orthodontics. All patients received postoperative rapid orthodontic treatment for 6-12 month after 2 weeks of operation. Using the straight arch wire techniques and the class Ⅲ intermaxillary traction, we removed the overcrowding upper and lower teeth, the compensatory axial tilt of teeth, and the deviation of the dental arch and maintained the neutral relationship of the molar. The mandible Hawley retaining devices were used during the maintaining stage. Results: The cases in study acquired satisfactory clinical outcome, which included the shortened overall treatment duration, the significantly improved facial features, the corrected occlusion relationship, and the restored function of mastication and temporomandibular joint. There were some complications as follows: intraoperative fracture (6 cases, 3.24%), the inferior alveolar nerve bundle injury (2 cases, 1.1%), and temporary open-bite that diminished by inter-maxillary elastic distraction one month after operation (19 cases, 10%). All cases in this study accepted postoperative orthodontic treatment. Follow-up time ranged from 6 months to 5 years. The cephalometric analysis results of 126 cases who had complete image data and over 6 months of follow-up showed that hard and soft tissue indexes were restored to normal range after combined orthognathic-orthodontic treatment. The stability of the maxillary and occlusive relationship of SFA(surgery-first approach) was similar to that of the COS(conventional orthodontics-first system) [relapse ratio=(T2-T1)/(T1-T0)×100%]. Over six months of follow-up , SNB and ANB showed that the average relapse ratio were 22% and 19.8%, whereas the relapse angle are less than 2°. Conclusions The Surgery-first approach could be used to treat most patients with Angle skeletal Class Ⅲ malocclusion, but the indications and the surgical procedures should be noticed and chosen.

Objective To analyze the median urinary iodine(MUI)level in normal pregnant women based on World HeMth Organization(WHO) recommended criterion,and to provide the MUI reference values for monitoring and evaluating iodine nutrition during pregnancy and related studies.Methods Total 604 normal pregnant and 192 non-pregnant women(as a comparison)were selected from a cross-sectional survey.These women were all healthy,iodine sufficient,with normal thyroid function,and negative anti-thyroid antibodies.The iodine content in drinking water,edible salt,and urine was determined by standard methods,and serum TSH,FT4,FT3,thyroid peroxidaseantibody(TPOAb),and thyroglobulin antibody(TgAb)were measured using chemiluminescent immunoassay.Resuits (1)The iodine in drinking water was 3.0μg/L indicating such small amount of iodine could be neglected for daily iodine intake.(2)All women consumed iodized salt with the median iodine in salt of 31.7 mg/kg.The daily iodine intake of at least 240 μg could be roughly estimated if an average of 10 g salt was taken per person per day and further subtracted by 20%iodine lost during cooking,which could meet the iodine needs during pregnancy.(3)The MUI of 173.1μg/L was calculated from 604 pregnant women having 174.5,167.0,and 180.7 μg/L during the first,second,and third trimesters,respectively,reaching the optimal level of 150-249 μg/L recommended by WHO for pregnant women.However,our data showed relatively lower levels,not reaching 200μg/L.The MUI of 240.2μg/L was calculated from 192 non-pregnant women,reaching the level of"above requirement"(200-299μg/L) recommended by WHO for adults.(4)All women were euthyroid and antibody-negative,but the TSH level in pregnant women was lower than that in non-pregnant women,in particular during the first trimester,while FT4 and FT3 were considerably decreased compared with the non-pregnant(with an exception of FT4 in the first trimester),and both gradually declined with the gestational age.Conclusions The optimal MUI level of 150-249 μg/,L recommended by WHO can be applied to pregnant Chinese women,but our data provided a relatively low range of 150-200μ/L throughout pregnancy.The higher MUI of 240.2μg/L in non-pregnant women indicated that iodized salt with different contents should be supplied on market to meet the requirement of different groups of population.

Objective:To observe the effect of different iodine intake on the thyroid function in euthyroid adult persons.Methods:One hundred and sixty-one euthyroid healthy volunteers aged 18-24 years were randomly divided into 7 groups.Each group was assigned to receive 500 μg,750 μg,1 000 μg,1 250 μg,1 500 μg,and 2 000 μg iodide/day for four weeks.Serum concentrations of free triiodothyronine(FT3),free thyroxin(FT4)and sensitive thyroid-stimulating hormone(sTSH)were measured by chemolumineseenee assays.Results:Serum FT3 concentration was found a small decline within the normal range in all the iodide supplemented groups(P ＜ 0.05).The level of FT4 was significantly lower,when the dose was up to 1 500 μg (P ＜ 0.05).The level of serum sTSH was increased after 2 weeks iodide supplement in all groups,and after 4 weeks in 500 μg and 750 μg groups(P ＜ 0.05).No significant changes were observed in FT3,FT4 and sTSH between groups(P＞ 0.05).Conclusion:The thyroid function of normal people showed a rise in serum sTSH at a short time and a high-dose of iodine intake.
