Abstract
Objective: To explore the histopathological factors affecting the stiffness of papillary thyroid carcinoma (PTC). Methods: Ninety-six patients with PTC confirmed by surgery and pathology in Shanxi Bethune Hospital from January 2019 to December 2020 were selected, including 101 nodules. Two-dimensional ultrasound and shear-wave elastography (SWE) were performed before surgery and the average Young's modulus (Emean) of PTC nodules were measured. Histopathological examinations on the nodules were conducted after surgery to decide the lesion size, number of lesions, calcification type, presence or absence of capsular and extracapsular invasion, degree of fibrosis, microvessel density, and number of tumor cells. The correlations between the lesion size, degree of fibrosis, microvessel density, and number of tumor cells and the Emean were analyzed. The Emeans of nodules with different numbers of lesions, presence or absence of capsular and extracapsular invasion, and different pathological calcification types were compared. The multiple linear regression analysis was used to evaluate the histopathological factors influencing the Emean. Results: The ranges of the lesion sizes, degrees of fibrosis, microvascular density, numbers of tumor cells, and the Emeans of the 101 investigated PTC nodules were (1.29±0.95) cm, (30.64±18.37)%, (101.64±30.7) vessels per high power field, (373.52±149.87) cells per high power field, and (36.47±19.62) kPa, respectively. Correlation analysis showed that the lesion size of PTC and the degree of fibrosis were positively correlated with the Emean (r=0.660, P<0.001; r=0.789, P<0.001), while the microvessel density was negatively correlated with the Emean (r=-0.198, P=0.047). The Emean of the group with capsular and extracapsular invasion was higher than that of the group without (P=0.014). There were statistical differences in the Emeans among different types of pathological calcification (P<0.001). The multiple linear regression analysis showed that the lesion size (β=0.325, P<0.001), degree of fibrosis (β=0.563, P<0.001), psammoma bodies (β=0.177, P=0.001), stromal calcification (β=0.164, P=0.003), and mixed calcification of both psammoma bodies and stroma (β=0.163, P=0.003) were independent influencing factors for the Emean. The degree of fibrosis had the greatest impact on the Emean. Conclusions: The Emean of PTC lesions was correlated with the histopathological characteristics of PTC. The lesion size, degree of fibrosis, and calcification had significant impact on the Emean, among which the degree of fibrosis had the greatest impact.

Abstract
Objective: To monitor hemodynamic changes during serial balloon pulmonary angioplasty (BPA) for chronic thromboembolic pulmonary hypertension (CTEPH). Methods: General clinical data of CTEPH patients diagnosed from October 2017 to January 2022 in Beijing Chaoyang Hospital were collected, and 83 patients who underwent at least 1 BPA treatment were included to analyze their 6 min walking distance, WHO functional class, N-terminal B-type natriuretic peptide precursor (NT-proBNP), troponin I (cTnI) and haemodynamic indices. Baseline and follow-up after the final BPA clinical data and hemodynamics, functional status and serial hemodynamics before each series of BPA were collected to evaluate the efficacy of BPA for CTEPH patients. Complications and managements were documented to confirm the safety of BPA for CTEPH patients. Results: Three hundred and forty BPA procedures were performed in 83 CTEPH patients. The median number of BPA procedures was 4.0 and a total of 2104 vessels were dilated. In general, mPAP [from 50.0(42.0-55.25) mmHg(1 mmHg=0.133 kPa) to 32.0(27.0-42.0) mmHg, P<0.001], PVR[from (806.6±323.2) dyn·s·cm-5 to 420.0(295.0-613.5) dyn·s·cm-5, P<0.001] were significantly improved compared with baseline, but not CO and CI. Functional parameters including WHO functional class Ⅰ/Ⅱ/Ⅲ/Ⅳ (from 0/35/34/14 to 43/32/7/1, P<0.001), 6MWD [from 364.5(300.0-429.5)m to 461.0(409.0-501.0)m, P<0.001], NT-proBNP [from 1 357.0(232.0-2 715.0) ng/L to 141.0(57.0-627.8) ng/L,P<0.001] were significantly improved compared with baseline. A cumulative (compared to baseline) and serial (compared to preceding BPA session) analysis of the sequential BPA session confirmed that a major hemodynamic improvement in PVR and mPAP occurred in the first 3 serial BPA treatments. There was a dose-response relationship: the more segments that were treated, the greater were the subsequent reduction in PVR and mPAP. There were 32.0 complications (9.4%) associated with BPA procedures, and the most common complication was pulmonary hemorrhage caused by catheter-related vascular injury. Conclusions: BPA is an effective and safe alternative for technically non-operable CTEPH patients. The hemodynamic benefits of BPA in CTEPH patients were cumulative and correlated with the total number of vessels successfully dilated.

Abstract
Objective: To investigate the appropriate cut-off for diagnosis of primary aldosteronism (PA) by seated saline suppression test (SSST) based on liquid chromatography with tandem mass spectrometry (LC-MS/MS). Methods: In this cross-sectional study, patients who underwent SSST for suspected PA in the First Affiliated Hospital of Chongqing Medical University from January 2018 to March 2022 were evaluated. Briefly, 300 patients with PA and 119 with essential hypertension (EH) were included. Plasma aldosterone concentration (PAC) after SSST was determined by LC-MS/MS. Primary aldosteronism confirmatory testing (PACT) score was used as the reference standard for diagnosis of PA, and receiver operating characteristic (ROC) curve was used to explore the cut-off value. Results: The average age of the PA group was (50.8±10.5) years, and males accounted for 53.00% (n=159); the average age of the EH group was (49.4±11.2) years, and males accounted for 26.89% (n=32). The area under the ROC curve of PAC post-SSST was 0.819 (95%CI 0.775-0.862). When 40 pg/ml (110.8 pmol/L) was selected as the appropriate cut-off for diagnosis of PA, the sensitivity was 83.67% (95%CI 78.88%-87.56%) and specificity was 60.50% (95%CI 51.10%-69.21%). Thus, 95.09% (155/163) of patients with unilateral PA could be identified. Conclusion: PAC after SSST determined by LC-MS/MS has high efficacy for diagnosis of PA, and 40 pg/ml is recommended as the appropriate cut-off value.

Abstract
Background Ultrasonography of the uterine artery (UtA) in the first and second trimesters of pregnancy can assess uterine-placental blood perfusion and guide early clinical prevention. Establishing normal ranges of the UtA pulsatility index (UtA-PI) at 11-14 weeks of pregnancy is helpful for the early identification of high-risk pregnant women and improving the prognosis. This study aimed to establish a reference range of UtA-PI based on crown-rump length (CRL) for spontaneous and in vitro fertilization (IVF) singleton pregnancy during 11-14 weeks, respectively. Methods A prospective study was performed at Peking Union Medical College Hospital. Healthy, low-risk women with a singleton pregnancy at 11-14 gestational weeks were consecutively recruited for this study from December 2017 to December 2020. All participants underwent routine prenatal ultrasound examination. The CRL of the fetus and the UtA-PI were measured in both uterine arteries, and average values were calculated. The LMS method was used to fit the percentile (P)5, P10, P25, P50, P75, P90, and P95 curves of the UtA-PI value of spontaneous and IVF singleton pregnancy with CRL changes, respectively. Results A total of 1,962 pregnant women with normal fetuses were included in this study, including 1,792 pregnancies conceived naturally and 170 IVF fetuses. The UtA-PI reference range in the spontaneous pregnancy group was consistently higher than that in the IVF group during 11-14 weeks, and showed a statistically significant difference in UtA-PI for spontaneous and IVF pregnancies (P<0.001). According to the LMS method, each percentile curve of UtA-PI decreased with the increase of CRL in both the natural pregnancy group and the IVF group. The P95 range of UtA-PI for pregnant women with naturally conceived and IVF pregnancy was 2.74 to 2.11 and 2.50 to 1.94, respectively. The overall change of UtA-PI differentials of the two groups showed a downward trend and decreased slightly with the increase of CRL. Conclusions This study provided a single-center, large sample of data and constructed a CRL-based reference value of UtA-PI for spontaneous and IVF singleton pregnancy, which provides a reliable basis for early UtA evaluation and early clinical decision-making during 11-14 gestational weeks.

Abstract
Helvella is a widespread, frequently encountered fungal group appearing in forests, but the species diversity and molecular phylogeny of Helvella in China remains incompletely understood. In this work, we performed comprehensive phylogenetic analyses using multilocus sequence data. Six datasets were employed, including a five-locus concatenated dataset (ITS, nrLSU, tef1-α, rpb2, hsp), a two-locus concatenated dataset (ITS, nrLSU), and four single-locus datasets (ITS) that were divided based on the four different phylogenetic clades of Helvella recognized in this study. A total of I 946 sequences were used, of which 713 were newly generated, including 170 sequences of ITS, 174 sequences of nrLSU, 131 sequences of tef1-α, 107 sequences of rpb2 and 131 sequences of hsp. The phylogeny based on the five-locus concatenated dataset revealed that Helvellas. str. is monophyletic and four phylogenetic clades are clearly recognized, i.e., Acetabulum clade, Crispa clade, Elastica clade, and Lacunosa clade. A total of 24 lineages or subclades were recognized, II of which were new, the remaining 13 corresponding with previous studies. Chinese Helvella species are distributed in 22 lineages across four clades. Phylogenetic analyses based on the two-locus concatenated dataset and four single-locus datasets confirmed the presence of at least 93 phylogenetic species in China. Among them, 58 are identified as known species, including a species with a newly designated lectotype and epitype, 18 are newly described in this paper, and the remaining 17 taxa are putatively new to science but remain unnamed due to the paucity or absence of ascomatal materials. In addition, the Helvella species previously recorded in China are discussed. A list of 76 confirmed species, including newly proposed species, is provided. The occurrence of H. crispa and H. elastica are not confirmed although both are commonly recorded in China. Citation: Mao N, Xu YY, Zhang YX, Zhou H, Huang XB, Hou CL, Fan L (2023).

Abstract
Objective: To introduce the technique and clinical application of free lobed anteromedial thigh perforator pedicle flap. Methods: From September 2015 to September 2021, 72 patients with perforating buccal and oral cancer defects were treated at the Oncology Plastic Surgery Department of Hunan Cancer Hospital. There were 61 males and 11 females, with an average age of 36.7 years (31-56 years). According to Union for International Cancer Control (UICC) TNM staging, there were 20 cases of T3N1M0, 13 cases of T3N2M0, 24 cases of T4N0M0, and 15 cases of T4N1M0. All defects were planned to be repaired with free lobed anteromedial perforator flaps. When there was only one set of vascular pedicle, the perforating vascular pedicle artery was anastomosed with the superior thyroid artery, and the accompanying vein was anastomosed with the superior thyroid vein by end-to-end. Results: The areas of soft tissue defects after radical resection of oral and buccal cancers in 72 patients were between 5.0 cm × 4.0 cm and 11.0 cm×7.0 cm; the areas of the first anterior femoral skin islands were between 5.0 cm × 4.0 cm and 13.0 cm×7.0 cm; the areas of the second anterior femoral skin islands were between 5.0 cm × 3.0 cm and 10.0 cm × 7.0 cm; and all flap donor sites were directly closed. In 35 cases, the vascular pedicle was accompanied by a lateral femoral muscle flap for filling the gap defect at the base of the mouth. The average length of the vascular pedicles of the flaps was 7.2 cm (range: 6.8-8.2 cm). The average diameter of the vascular pedicle arteries was 1.6 mm (range: 1.4-2.2 mm). The blood flow reconstruction of flap was completed by anastomosing one accompanying vein. The average diameter of the accompanying veins was 2.1 mm (range: 1.6-2.8 mm). Postoperative hematoma occurred in 3 patients, with one having vascular crisis. After emergency exploration, 2 of them were successfully saved, and the other one had complete necrosis of skin flap, which was repaired by pedicled pectoralis major skin flap transplantation. With following up of 12-38 months, the appearances of the flaps were satisfactory without significant swelling. The mouth opening and language function were satisfactory in all cases, and only linear scars were left in the donor sites, with no significant impact on thigh functions. Five patients with local recurrence of tumor were treated with second radical resection and repair with pedicled pectoralis major myocutaneous flap. Six patients developed cervical lymph node metastasis (4 on the same side and 2 on the opposite side) and underwent neck dissection again. Conclusion: The anatomical basis of the branches of the anteromedial femoral perforating branches in the anterolateral region of the thigh can be helpful to prepare the anterolateral femoral lobed flap, which is suitable for repairing the perforating defects after the radical operation of oral and buccal cancers.

Abstract
Scars are problems that inevitably develop after deep dermal injury in the skin. Selecting appropriate photoelectric therapy for scars at different stages is an important part of scar management, which can shorten the acute inflammatory phase, accelerate scar maturation and regression, improve scar appearance and function, and reduce associated discomfort. Based on our team's practical experience and the current literature, this paper provides targeted photoelectric management protocols in the stages of wound healing, early scarring, hypertrophic scarring, and contracture scarring, with the aim of providing a reference for the development of standardized photoelectric therapy protocols for scars.

Abstract
Reactor neutrino experiments play a crucial role in advancing our knowledge of neutrinos. In this Letter, the evolution of the flux and spectrum as a function of the reactor isotopic content is reported in terms of the inverse-beta-decay yield at Daya Bay with 1958 days of data and improved systematic uncertainties. These measurements are compared with two signature model predictions: the Huber-Mueller model based on the conversion method and the SM2018 model based on the summation method. The measured average flux and spectrum, as well as the flux evolution with the ^{239}Pu isotopic fraction, are inconsistent with the predictions of the Huber-Mueller model. In contrast, the SM2018 model is shown to agree with the average flux and its evolution but fails to describe the energy spectrum. Altering the predicted inverse-beta-decay spectrum from ^{239}Pu fission does not improve the agreement with the measurement for either model. The models can be brought into better agreement with the measurements if either the predicted spectrum due to ^{235}U fission is changed or the predicted ^{235}U, ^{238}U, ^{239}Pu, and ^{241}Pu spectra are changed in equal measure.

Abstract
Although the treatment of patients with burns combined with inhalation injury has achieved great success, from the perspective of epidemiology, inhalation injury is still the most common cause of death in mass burns. Such patients often suffered burns of large total body surface area, which is difficult to treat, with airway management as one of the core links. Physical airway clearance technique (ACT) acts on a patient's respiratory system by physical means, to discharge secretions and foreign bodies in the airway, achieve airway clearance, and improve gas exchange. In addition, the technique can prevent or alleviate many complications, thereby improving the clinical outcome of patients with inhalation injury. This article reviews the application of physical ACT in the field of inhalation injury, and to provide decision-making basis for clinical medical staff to choose physical ACT corresponding to the patient's condition.

Abstract
Objective: To analyze the expression levels of differentiation cluster 47 (CD47), signal regulatory protein α (SIRP-α), proto-oncogene (MYC) and proliferating cell associated antigen (Ki67) proteins in peripheral blood circulating tumor cells (CTC) from patients with diffuse large B-cell lymphoma and their predictive efficiency for tumor recurrence. Methods: The data of 82 patients with diffuse large B-cell lymphoma who were confirmed by histopathology and were in remission after chemotherapy in the Hematology Department of Linyi People's Hospital from January 2018 to January 2021 were retrospectively analyzed. There were 44 males and 38 females, and aged from 50 to 75 (63.8±4.6) years. The patients were divided into recurrent group (n=36) and non-recurrent group (n=46) according to their recurrence within 1 year after remission. The fasting peripheral venous blood samples (4 ml) from patients in the morning were collected, and the CTC were isolated. The expression levels of CD47, SIRP-α, MYC and Ki67 proteins in CTC were detected by Western blotting. The correlations between CD47 expression level and SIRP-α, MYC and Ki67 expression levels were analyzed by Pearson correlation analysis. The predictive efficiency of CD47, SIRP-α, MYC and Ki67 expression levels on tumor recurrence was evaluated by receiver operating characteristic (ROC) curves, and the areas under the curve (AUC) were calculated. Results: The expression levels of CD47, SIRP-α, MYC and Ki67 in recurrent group were 2.24±0.23, 1.17±0.12, 1.98±0.20 and 2.63±0.27, while those in non-recurrent group were 2.04±0.21, 1.31±0.13, 1.53±0.16 and 2.24±0.25. The expression levels of CD47, MYC and Ki67 in the recurrent group were higher than those in the non-recurrent group, while the expression levels of SIRP-α were lower than those in the non-recurrent group (all P<0.001). In 82 patients, the expression levels of CD47, SIRP-α, MYC and Ki67 were 2.13±0.22, 1.25±0.13, 1.73±0.18 and 2.41±0.26, respectively. The expression level of CD47 was negatively correlated with the expression level of SIRP-α (r=-0.308, P=0.005), but positively correlated with the expression level of MYC and Ki67 (r=0.484 and 0.332, P=0.012 and 0.003). The sensitivity of CD47, SIRP-α, MYC and Ki67 expression levels in predicting recurrence of diffuse large B-cell lymphoma was 66.7%, 72.2%, 72.2% and 66.7%, with the specificity of 67.4%, 71.7%, 67.4% and 71.7%, and AUC (95%CI) of 0.694 (0.582-0.791), 0.693 (0582-0.790), 0.714 (0.603-0.808) and 0.709 (0.598-0.804), respectively. The sensitivity of the combined detection of the above four indicators was 83.3%, with the specificity of 78.3% and the AUC (95%CI) of 0.864 (0.771-0.930), which was higher than those of the individual detection of each indicator (all P<0.05). Conclusions: The expression level of CD47 was negatively correlated with the expression level of SIRP-α, but positively correlated with the expression level of MYC and Ki67. The expression levels of CD47, SIRP-α, MYC and Ki67 have certain predictive value for tumor recurrence in patients with diffuse large B-cell lymphoma, and the predictive efficiency of combined detection is higher than single indicator detection.

Abstract
Objective: The direction and intensity of population aging on the burden of non-communicable diseases (NCDs) in China from 1990 to 2019 were analyzed, and the burden of NCDs in 2050 was predicted. Methods: The disease-specific disability-adjusted life years (DALYs), years of life lost (YLLs), and years lived with disability (YLDs) in the Chinese population from 1990 to 2019 were obtained from the Global Burden of Disease Study.The differences in indicators from 1990 to 2019 were attributed to the contribution of age structure, population size, and all other causes. The Bayesian age-time-cohort models were used to predict DALYs from NCDs to 2050. Results: The absolute level of DALYs caused by NCDs increased by 7.460 million from 1990 to 2019, and the age structure contributed 186.0% (95% Uncertainty Intervals (UIs): 178.4%-193.6%), population size contributed 77.0% (95% UIs: 69.5%-80.8%), all other causes contributed -163.0% (95% UIs:-163.1%- -159.3%). DALYs caused by NCDs consist of 2.527 million YLLs and 4.934 million YLDs, in which the contribution of age structure to YLLs and YLDs was 414.6% (95% UIs: 396.2%-432.5%) and 69.1% (95% UIs: 66.7%-71.4%), respectively. From 2019 to 2050, the diseases with increased DALYs due to changes in age structure are cardiovascular diseases, neoplasms, chronic respiratory diseases, neurological disorders, sense organ diseases, diabetes and kidney diseases, musculoskeletal disorders, digestive diseases, mental disorders, and skin and subcutaneous diseases in descending order. Conclusions: From 1990 to 2019, except for skin and subcutaneous diseases, the burden of other NCDs attributable to population aging increased, mainly due to disability. By 2050, the burden of NCDsattributable to population aging will continue to rise.

Abstract
BACKGROUND Perianal fistulas, characterised as granulomatous inflammation of fistulas around the anal canal, are associated with significant morbidity resulting in a negative impact on quality of life and a tremendous burden to the healthcare system. Treatment of anal fistulas usually consists of anal surgery; however, results of closure rates are not satisfactory especially with complex perianal fistulas, after which many patients may suffer from anal incontinence. Recently, the administration of mesenchymal stem cells (MSCs) has shown promising efficacy. Herein, we aim to explore whether MSCs are effective for complex perianal fistulas and if they have either short-term, medium-term, long-term or over-long-term efficacy. Additionally, we want to elucidate whether factors such as drug dosage, MSC source, cell type, and disease aetiology influence treatment efficacy. We searched four online databases and analysed data based on information within the clinical trials registry. The outcomes of eligible trials were analysed with Review Manager 5.4.1. Relative risk and related 95% confidence interval were calculated to compare the effect between the MSCs and control groups. In addition, the Cochrane risk of bias tool was applied to evaluate the bias risk of eligible studies. Meta-analyses showed that therapy with MSCs was superior to conventional treatment for complex perianal fistulas in short-, long- and over-long-term follow-up phases. However, there was no statistical difference in treatment efficacy in the medium term between the two methods. Subgroup meta-analyses showed factors including cell type, cell source and cell dosage were superior compared to the control, but there was no significant difference between different experimental groups of those factors. Besides, local MSCs therapy has shown more promising results for fistulas as a result of Crohn's Disease (CD). Although we tend to maintain that MSCs therapy is effective for cryptoglandular fistulas equally, more studies are needed to confirm this conclusion in the future. SHORT CONCLUSION MSCs Transplantation could be a new therapeutic method for complex perianal fistulas of both cryptoglandular and CD origin showing high efficacy in the short-term to over-long-term phases, as well as high efficacy in sustained healing. The difference in cell types, cell sources and cell dosages did not influence MSCs' efficacy.

Abstract
Objective: To investigate the treatment and maternal and fetal outcomes of pregnant women with aortic dissection (AD). Methods: The clinical data of 11 pregnant women with AD treated at the First Affiliated Hospital of Air Force Military Medical University from January 1st, 2011 to August 1st, 2022 were collected, and their clinical characteristics, treatment plans and maternal and fetal outcomes were analyzed retrospectively. Results: (1) Clinical characteristics: the age of onset of 11 pregnant women with AD was (30±5) years old, and the week of pregnancy of onset was (31.4±8.0) weeks. Clinical manifestations: the main symptoms were sudden onset of chest and back pain or low back pain. Type of AD: 8 cases of Stanford type A, and 3 cases of type B. The aortic width was (42±11) mm. Diagnostic methods: the diagnosis of AD was confirmed by transthoracic echocardiography (TTE), computed tomography angiography (CTA) or enhanced CT examination, among which 4 cases were confirmed by CTA examination, 4 cases by TTE examination, and 3 cases by enhanced CT examination. Laboratory results: white blood cell count was (15.4±8.7) ×109/L, neutrophil count was (13.5±8.5) ×109/L, the median D-dimer level was 2.7 mg/L (2.1-9.2 mg/L), and the median fibrin degradation products level was 12.0 mg/L (5.4-36.1 mg/L). (2) Treatments: all 11 patients were admitted to hospital in emergency. Before operation, the departments of cardiac surgery, obstetrics, pediatrics and anesthesiology cooperated to develop individualized treatment plan. Aortic surgery was performed in 11 pregnant women with AD. In 6 of them, pregnancy termination was performed at the same time as aortic surgery, and aortic surgery was performed after cesarean section. Four cases of pregnancy termination and aortic operation were performed by stages, including aortic operation after cesarean section in 2 cases, and cesarean section after aortic operation in 2 cases. One case (12+6 weeks of gestation) had spontaneous abortion on the day after aortic surgery. The gestational age of the 11 patients on pregnancy termination was (32.9±7.4) weeks. Aorta surgical methods: 7 patients received under extracorporeal circulation ascending aorta replacement ± aortic valve replacement ± coronary artery transplantation (or coronary artery bypass transplantation)± left and right coronary Cabrol + total arch replacement (or aortic arch replacement)± stent implantation, 1 patient received under extracorporeal circulation aortic root replacement, and 3 patients underwent aortic endoluminal isolation. (3) Maternal and fetal outcomes: among the 11 pregnant women with AD, 9 (9/11) survived, 2 (2/11) died with lower limb ischemia before the onset of the disease. A total of 10 newborns were born in 9 pregnant women after delivery (1 of them was twins), and the 2 cases were spontaneous abortion after aortic surgery in the first trimester (12+6 weeks) and fetal death after hysterotomy in the second trimester (26+3 weeks), respectively. Among the 10 surviving neonates, 3 were full-term infants and 7 were premature infants. The birth weight of newborn was (2 651±784) g. Respiratory distress syndrome was found in 6 cases. The newborns were followed up for (5.6±3.6) years after birth, and the infants developed well during the follow-up period. Conclusions: Pregnancy complicated with AD is dangerous, and chest and back pain is the main clinical manifestation of this disease. With early identification and selection of appropriate diagnostic methods, multidisciplinary diagnosis and treatment, mother and children could obtain good outcomes.

Abstract
We present a new determination of the smallest neutrino mixing angle θ_{13} and the mass-squared difference Δm_{32}^{2} using a final sample of 5.55×10^{6} inverse beta-decay (IBD) candidates with the final-state neutron captured on gadolinium. This sample is selected from the complete dataset obtained by the Daya Bay reactor neutrino experiment in 3158 days of operation. Compared to the previous Daya Bay results, selection of IBD candidates has been optimized, energy calibration refined, and treatment of backgrounds further improved. The resulting oscillation parameters are sin^{2}2θ_{13}=0.0851±0.0024, Δm_{32}^{2}=(2.466±0.060)×10^{-3} eV^{2} for the normal mass ordering or Δm_{32}^{2}=-(2.571±0.060)×10^{-3} eV^{2} for the inverted mass ordering.

Abstract
Objective: To understand the current situation of long working hours exposure of couriers in Zhejiang Province, and to analyze the influence of long working hours exposure levels on their occupational stress and depression symptoms, and provide a basis for promoting the physical and mental health of couriers. Methods: From September to December 2021 , 1159 couriers from Zhejiang Express Transport Companies were selected as respondents by cluster sampling, and their basic information were collected. The occupational stress and depression symptoms of the couriers were assessed using the Core Occupational Stress Scale (COSS) and the Patient Health Questionnaire-9 (PHQ-9). The effects of long work hours (>48 h per week) on the occupational stress and depression symptoms of the couriers were analyzed. Results: The average age of 1159 courier in Zhejiang Province was (33.24±8.42) years, the average weekly working hours were (63.21±18.77) h, and 75.15% (871/1159) were long-term workers. The detection rates of occupational stress and depression symptoms in courier were 32.44% (376/1159) and 32.53% (377/1159), respectively. There were significant differences in the detection rates of occupational stress and depression symptoms among couriers with different ages, educational background, marital status, monthly average income, length of service, position or post, shift status, drinking status, and average weekly working hours (P <0.05). The adjusted logistic regression analysis showed that, after adjusting for the influence of confounding factors such as age, educational background, marital status, monthly average income, length of service, position or post, shift status and drinking status, compared with the weekly working hours ≤48 h, weekly working hours of 63-77 h, 78-92 h, ≥93 h were the risk factors for occupational stress (OR=1.547, 95%CI: 1.019-2.350; OR=1.886, 95%CI: 1.184-3.006; OR=2.338, 95%CI: 1.188-4.062) and depression symptoms (OR=1.897, 95%CI: 1.258-2.860; OR=2.041, 95%CI: 1.290-3.230; OR=4.978, 95%CI: 2.551-9.715) of couriers (P<0.05) . Conclusion: Long working hours could increase the risk of occupational stress and depression symptoms among couriers. It is necessary to arrange working hours reasonably to reduce the occurrence of occupational stress and depression symptoms of couriers.

Abstract
Polycystic ovary syndrome (PCOS) is a common endocrine disease in women of childbearing age, which seriously affects women's reproductive health. In recent years, more and more studies have found that serum anti-Müllerian hormone (AMH) has certain significance in the diagnosis and treatment evaluation of PCOS. In addition, with the improvement of detection methods, more attention has been paid to the significance of female androgens and AMH in the evaluation of PCOS. This article reviews the recent research progress of serum AMH and androgens in the evaluation of PCOS.

Abstract
Objective: To analyze the effect of selective bronchial occlusion (SBO) in the treatment of intractable pneumothorax. Methods: A total of 86 patients with refractory pneumothorax treated with SBO in the Department of Respiratory and Critical Care Medicine, the Second Affiliated Hospital of Fujian Medical University from January 1, 2019 to December 31, 2021 were included in this study. The basic information, diagnosis and treatment of the patients were collected and analyzed based on their inpatient records. Results: The age of the subjects was (62±11) years old, and 83 cases (96.5%) were male. The first time SBO cure rate was 30.2% (26/86). The effective rate of the first time SBO treatment was 38.4% (33/86), and the final cure rate of SBO was 59.3% (51/86). The total cure rate of SBO combined with other therapies was 73.3% (63/86). The median time [M (Q1, Q3)] from the first plugging to the complete cessation of air leakage in SBO cured patients was 6.5 (3, 7) days, which was shorter than that in the final extubation patients after SBO [11 (7, 19) days] (H=30.24, P<0.001). The median [M (Q1, Q3)] length of hospital stay of the first SBO cured patients was 19 (14, 25) days, which was shorter than that of all patients [28 (19, 37) days] (H=12.89, P=0.002). The median [M (Q1, Q3)] hospitalization expenses of patients with first SBO cure, effective SBO treatment and ineffective SBO treatment were 23 187 (18 906, 27 798), 41 580 (29 388, 50 762) and 38 462 (27 542, 51 720) yuan, respectively, and the difference was statistically significant (H=18.58, P<0.001). The incidence of complications after SBO was 7.59% (11/145). Conclusion: SBO has good efficacy and relative high safety in the treatment of intractable pneumothorax.

Abstract
This Letter reports the first measurement of high-energy reactor antineutrinos at Daya Bay, with nearly 9000 inverse beta decay candidates in the prompt energy region of 8-12 MeV observed over 1958 days of data collection. A multivariate analysis is used to separate 2500 signal events from background statistically. The hypothesis of no reactor antineutrinos with neutrino energy above 10 MeV is rejected with a significance of 6.2 standard deviations. A 29% antineutrino flux deficit in the prompt energy region of 8-11 MeV is observed compared to a recent model prediction. We provide the unfolded antineutrino spectrum above 7 MeV as a data-based reference for other experiments. This result provides the first direct observation of the production of antineutrinos from several high-Q_{β} isotopes in commercial reactors.

Abstract
OBJECTIVE To investigate the pharmacist's knowledge about rational use of antimicrobials in Shanxi of China, so as to find out the problems and provide support for the management of antimicrobials. METHODS A questionnaire survey was conducted, which included the basic information of the respondents, the basic knowledge about antimicrobial management and the related knowledge about antimicrobial drugs. SPSS 25.0 was used for statistical analysis. RESULTS A total of 462 pharmacists were investigated. The average score of the knowledge related to rational use of antimicrobials was 10.49 ± 4.05. It showed that the hospital type, grade, pharmacist's education, professional title and years of experience had effect on the pharmacist's knowledge level about antimicrobial drugs (P < 0.05). Multivariable logistic regression analysis showed that hospital grade and pharmacist's education were the main influencing factors (P < 0.05). CONCLUSION Pharmacists have insufficient knowledge about the rational use of antibacterial drugs. It is essential to strengthen the training in management regulations and application of antibacterial drugs.

Abstract
A joint determination of the reactor antineutrino spectra resulting from the fission of ^{235}U and ^{239}Pu has been carried out by the Daya Bay and PROSPECT Collaborations. This Letter reports the level of consistency of ^{235}U spectrum measurements from the two experiments and presents new results from a joint analysis of both data sets. The measurements are found to be consistent. The combined analysis reduces the degeneracy between the dominant ^{235}U and ^{239}Pu isotopes and improves the uncertainty of the ^{235}U spectral shape to about 3%. The ^{235}U and ^{239}Pu antineutrino energy spectra are unfolded from the jointly deconvolved reactor spectra using the Wiener-SVD unfolding method, providing a data-based reference for other reactor antineutrino experiments and other applications. This is the first measurement of the ^{235}U and ^{239}Pu spectra based on the combination of experiments at low- and highly enriched uranium reactors.

Abstract
Objective: To explore the clinical effects of transplantation of turbocharged bipedicle deep inferior epigastric perforator (DIEP) flap in breast reconstruction. Methods: A retrospective observational study was used. From December 2008 to December 2016, 24 patients who met the inclusion criteria were treated in the Department of Plastic Surgery of Hunan Cancer Hospital, all patients were female, aged 28-51 (36.5±1.6) years. All cases received turbocharged bipedicle DIEP flap for two-staged breast reconstruction. According to the patterns of turbocharged vessels anastomosis, the turbocharged bipedicle DIEP flaps with length of (27.5±0.3) cm and width of (12.8±1.4) cm, were divided into three types: distal end of pedicle anastomosis type, main branch of pedicle anastomosis type, and muscular branch of pedicle anastomosis type. After complete hemostasis in the donor region, the anterior sheath was repaired with intermittent suture, and umbilical reconstruction was completed. Two negative pressure drainage tubes were indwelled, and subcutaneous tissue and skin were sutured layer by layer. The specific ways of vascular anastomosis of the flap pedicle with the internal thoracic vessels of recipient site included anastomosing the proximal end of one artery and one vein, anastomosing the proximal and distal end of one artery and one vein, and anastomosing the proximal end of one artery and two veins. Postoperatively, the survival and blood supply of flaps were observed. The patients were followed up to observe the reconstructed breast shape satisfaction, donor site complications, abdominal wall function, and scar hyperplasia. Results: All turbocharged bipedicle DIEP flaps for two-staged breast reconstruction survived well, with good blood supply. During follow-up for 14 to 56 (20±6) months, the shape of reconstructed breasts was satisfied. Only linear scar was left in the donor sites of abdomen with no complications, and the function of abdominal wall was not affected. Conclusions: For patients with clear indications, transplantation of free turbocharged bipedicle DIEP flap is a safe, reliable, and satisfactory choice for breast reconstruction with autologous tissue.

Abstract
Objective: To establish a dental fluorosis model of SD rats with various degrees, to observe the microstructures of enamel samples under scanning electron microscope and to clarify the changes of enamel microstructures with various degrees of dental fluorosis, so as to provide clinical reference for the treatment of patients with moderate and severe dental fluorosis. Methods: Thirty male SD rats (6 weeks of age) were randomly divided into 3 groups with 10 rats in each group. The control group was fed with deionized water without fluoride, the low fluoride group was fed with 50 mg/L NaF deionized water and the high fluoride group was fed with 100 mg/L NaF deionized water in order to establish the dental fluorosis model of rats. After feeding for 6 weeks, the rats were sacrificed and the mandibular incisor teeth were collected and recorded. The surface and sagittal plane of each tooth were observed by scanning electron microscopy and the enamel thickness was measured. Results: In the control group, the enamel color was brown yellow. Enamel color discoloration occurred both in low-fluoride group and high-fluoride group. The enamel color in low-fluoride group was mostly yellow and white striped while in high-fluoride group was mostly chalky white. Under electronic microscope, the enamel rods were alternately arranged and their structure was clear and plump in the control group. The enamel rods of moderate fluorosis were arranged in a straight orientation like tips of bamboo shoots. The enamel rods of severe fluorosis, however, became thinner and the tips of rods were broken. In the control group, sagittal images of enamel turned out to be a dense outer structure with clear boundaries among the inner. The structure of the middle layer was reticulated showing a clear boundary with middle and outer layers. The structure of enamel rods in the inner layers was arranged vertically and horizontally. In the moderate fluorosis group, the outer layer of the enamel became thinner and the middle layer disappeared although the boundary between the outer and middle layers was still clear. In the inner layer, the vertically arranged enamel rods seemed still clear, however the horizontal enamel rods disappeared. In the severe fluorosis group, the outer layer could not be traced. The middle layer was exposed to the air and the inner enamel rods contracted. The inner layers of the enamel had gradually become thinner with the development of the dental fluorosis. The thicknesses of inner layers in control, moderate and the severe groups were (180.71±7.01), (157.10±11.04) and (121.10±12.56) μm respectively. As for the thicknesses of the full layers in the above mentioned three groups, the same trend was observed. The thicknesses, in order of the severity of dental fluorosis, were (241.54±7.76), (207.42±14.36) and (143.79±14.60) μm. Conclusions: With the development of dental fluorosis, the outer enamel layers became thinner or disappeared and the inner enamel layers became thinner or lost its normal structure as well. It is highly recommended that the resin penetration could be used for the proper treatment of moderate and severe dental fluorosis and the strong bleaching and the micro-grinding should be used cautiously.

Abstract
Objective: To compare clinical characteristics of sporadic gastrinoma and multiple endocrine neoplasia type 1 (MEN1)-related gastrinoma. Methods: A retrospective cohort study was conducted. Patients with clinical manifestations of Zollinger-Ellison syndrome, pathological diagnosis as neuroendocrine neoplasm (NEN) and complete clinical and follow-up data were enrolled. Patients with only high gastric acid secretion but without evidence of NEN, or with other concurrent non-NEN tumors were excluded. According to the above criteria, the clinicopathological data of 52 cases of gastrinoma diagnosed from April 2003 to December 2020 in the First Affiliated Hospital, Sun Yat-sen University, were collected. Patients who met the diagnostic criteria of gastrinoma and met one of the following conditions were diagnosed as MEN1-related gastrinoma: (1) the presence of pathogenic mutations in the MEN1 gene confirmed by genetic testing; (2) NENs involving two or more endocrine glands, namely, pituitary, parathyroid, thymic, pancreatic, and adrenal NENs; (3) NEN and at least one first-degree relatives diagnosed as MEN1. The remaining gastrinomas were defined as sporadic gastrinoma. Student's t test and chi-square test were used for statistical analysis. Clinicopathological characteristics, endoscopic findings, imaging characteristics, treatment, and prognosis of sporadic and MEN1-related gastrinoma were compared. Results: Among 52 patients with gastrinoma, 33 were sporadic gastrinoma and 19 were MEN1-related gastrinoma. The common symptoms of both sporadic and MEN1-related gastrinomas were diarrhea (24/33, 72.7%; 17/19, 89.5%) and abdominal pain (19/33, 57.6%; 9/19, 47.4%). Compared with sporadic gastrinoma, MEN1-related gastrinoma needed longer time for diagnosis [(7.4±4.9) years vs. (3.9±5.2) years, t=-2.355, P=0.022), were more likely multiple tumors [47.4% (9/19) vs. 15.2% (5/33), χ(2)=6.361, P=0.012], had smaller diameter [(1.7±1.0) cm vs. (3.1±1.8) cm, t=2.942, P=0.005), presented the lower tumor grade [G1: 83.3% (15/18) vs. 39.4% (13/33); G2: 11.1% (2/18) vs. 54.5% (18/33); G3: 5.6% (1/18) vs. 6.1% (2/33), Z=-2.766, P=0.006], were less likely to have serum gastrin which was 10 times higher than normal [11.8% (2/17) vs. 56.0% (14/33), χ(2)=8.396, P=0.004], had higher probability of complication with type 2 gastric neuroendocrine tumors (g-NET) [31.6% (6/19) vs. 3.0%(1/33), χ(2)=6.163, P=0.013], and had lower rate of liver metastasis [21.1% (4/19) vs. 51.5% (17/33), χ(2)=4.648, P=0.031). There was no obvious difference between sporadic gastrinomas and MEN1-related gastrinomas in endoscopic findings. Both types presented enlarged and swollen gastric mucosa under the stimulation of high gastric acid, and multiple ulcers in the stomach and duodenum could be seen. Gastrinoma with type 2 g-NET presented multiple polypoid raised lesions in the fundus and body of the stomach. (68)Ga-SSR-PET/CT scan had a 100% detection rate for both types while (18)F-FDG-PET/CT scan had a higher detection rate for sporadic gastrinoma compared with MEN1-related gastrinoma [57.9% (11/19) vs. 20.0% (3/15), χ(2)=4.970, P=0.026]. Among the patients with sporadic gastrinoma, 19 received surgical treatment, 1 underwent endoscopic submucosal dissection, 8 underwent transcatheter arterial embolization (TAE), and 5 underwent surgery combined with TAE. Among patients with MEN1-related gastrinoma, 13 received surgical treatment, and the other 6 received conservative treatment. The median follow-up of all the patients was 21.5 (1-129) months, and the 5-year survival rate was 88.4%. The 5-year survival rate of patients with sporadic and MEN1-related gastrinomas was 89.5% and 80.0% respectively (P=0.949). The 5-year survival rate of patients with and without liver metastasis was 76.2% vs. 100%, respectively (P=0.061). Conclusions: Compared with sporadic gastrinoma, MEN1-related gastrinoma has longer diagnosis delay, smaller tumor diameter, lower tumor grading, lower risk of liver metastasis, and is more likely to complicate with type 2 g-NET, while there is no difference in survival between the two tumor types.

Abstract
Objective: To systematically summarize and assess risk prediction models for occurrence of cervical cancer and to provide evidence for selecting the most reliable model for practice, and guide cervical cancer screening. Methods: Two groups of keywords related to cervical cancer and risk prediction model were searched on Chinese databases (CNKI, and Wanfang) and English databases (PubMed, Embase, and Cochrane Library). Original articles that developed or validated risk prediction models and published before November 21, 2019, were selected. Information form was created based on the CHARMS checklist. The PROBAST was used to assess the risk of bias. Results: 12 eligible articles were identified, describing 15 prediction models, of which five were established in China. The predicted outcomes included multiple stages from cervical precancerous lesions to cancer occurrence, i.e., abnormal Pap smear (1), occurrence or recurrence of CIN (9), and occurrence of cervical cancer (5), etc. The most frequently used predictors were HPV infection (12), age (7), smoking (5), and education (5). There were two models using machine learning to develop models. In terms of model performance, the discrimination ranged from 0.53 to 0.87, while only two models assessed the calibration correctly. Only two models were externally validated in Taiwan of China, using people in different periods. All of the models were at high risk of bias, especially in the analysis domain. The problems were concentrated in the improper handling of missing data (13), preliminary evaluation of model performance (13), improper use of internal validation (12), and insufficient sample size (11). In addition, the problems of inconsistency measurements of predictors and outcomes (8) and the flawed report of the use of blindness for outcome measures (8) were also severe. Compared with the other models, the Rothberg (2018) model had relatively high quality. Conclusions: There are a certain number of cervical cancer risk prediction models, but the quality is poor. It is urgent to improve the measurement of predictors and outcomes, the statistical analysis details such as handling missing data and evaluation of model performance and externally validate existing models to better guide screening.

Abstract
Objective: To analyze the clinical characteristics and factors associated with human respiratory syncytial virus (HRSV) infection in preterm infants within the first 2 years of life. Methods: Children with respiratory tract infections admitted to Shenzhen Children's Hospital during the 3-year period from January 2016 to December 2018 who were <2 years old and whose gestational age at birth was <37 weeks were selected, and those who met the diagnostic criteria for RSV infection were categorized as the positive case group, and those who had no detectable influenza virus, parainfluenza virus and adenovirus antigens were categorized as the negative group. The clinical characteristics of the case group were retrospectively analyzed. A multivariable logistic regression model was used to analyze the associated factors. Results: A total of 1, 483 children were included, of whom 149 (10.1%) were HRSV positive (case group) and 447 (30.1%) were in the negative group (control group). In the case group, there were 88 (59.1%) male and 61 (40.1%) female children; 127 children (85.2%) in the mild-to-moderate disease group and 22 children (14.8%) in the severe disease group. The number of cases in the severe disease group was greater than that in the mild-to-moderate disease group [(17 cases, 77.3%) than (59 cases, 46.5%)], with statistical significance (P=0.010). A total of 117 cases (78.5%) had onset from February to July. Multivariable analysis showed that males [OR (95%CI) of 0.105 (0.013-0.112)], age at month [0.045 (0.036-0.112)], congenital heart disease [0.388 (0.206-0.940)] and bronchopulmonary dysplasia [0.622 (0.484-0.927)] were positively associated with HRSV infection in preterm infants. Conclusion: The high prevalence of HRSV infection in preterm infants in Shenzhen is from February to July each year, and male children are more common. Young age, congenital heart disease and bronchopulmonary dysplasia are all independent risk factors for HRSV infection in preterm infants.

Abstract
Objective: To explore the clinical effect of the fractional carbon dioxide laser in the treatment of contracture scars. Methods: A retrospective before-after self-control study was conducted. From December 2016 to April 2021, 16 patients (7 males and 9 females, aged 3-49 years) with contracture scars causing impaired function of the adjacent joint were admitted to Shanghai Ninth People's Hospital Affiliated to Shanghai Jiao Tong University School of Medicine. Eighteen joint scars of 16 patients were treated with fractional carbon dioxide laser every 2-3 months until the joint retained its normal range of motion or the effect plateaued. The treatment times of each patient were recorded. Before the first treatment and 6 months after the last treatment, the ranges of motion of the affected joint were measured in each patient, and the difference was calculated, meanwhile, the Vancouver Scar Scale (VSS) was used to evaluate the scar of each patient. In the treatment of 1 joint scar in each of 6 patients (totally 6 times of treatments), the ranges of motion of the affected joint before the current treatment, immediately after the treatment, and at the first follow-up after the treatment were documented, and the differences between the ranges before and immediately after the treatment as well as between the ranges before and at the first follow-up after the treatment were calculated. Adverse effects after the treatment in the treatment area were documented. At the last follow-up, a self-made questionnaire was used to collect the implementation status of the physical therapy and other scar management modalities during the treatment interval and follow-up period. Data were statistically analyzed with Wilcoxon rank sum test. Results: Eighteen joint scars in 16 patients received 2 (1, 3) times of fractional carbon dioxide laser treatment. The range of motion of the affected joint of 16 patients 6 months after the last treatment was 56.5 (39.0, 128.8)°, notably higher than 38.4 (22.9, 116.3)° before the first treatment (Z=-3.724, P<0.01), showing a remarkable improvement by 17.4 (8.0, 24.1)°. The vascular distribution, softness, and thickness scores, and total score in VSS scoring of scars of 16 patients 6 months after the last treatment were significantly lower than those before the first treatment (Z=-2.989, -3.762, -2.814, -3.739, P<0.01), with the most obvious improvement in softness. In 6 times of treatments, the range of motion of the affected joint immediately after treatment and at the first follow-up of (2.5±0.6) months after treatment were 156.2 (148.0, 164.2)° and 160.2 (156.7, 166.4)°, both notably higher than 151.4 (145.7, 155.3)° before treatment (Z=-2.201, -2.201, P<0.05), showing a remarkable improvement by 9.1 (4.4, 13.0)° and 13.1 (8.0, 15.7)°, respectively. No adverse effects such as blisters, infection, or hypertrophic scar formation were observed in the treatment area of 16 patients after treatment. Most patients adopted physical therapy, compression, silicone gel or sheets, and braces during the treatment interval and follow-up period. Conclusions: The fractional carbon dioxide laser can soften the scar and increase the range of motion of the affected joint, which is suitable for the clinical treatment of mild contracture scars.

Abstract
Pathological scars cause both local physical discomforts and mental disorders for patients. With the development of research, botulinum toxin type A (BTX-A) has been gradually used in the clinical treatment of scars. This article summarizes three potential mechanisms of BTX-A, including early tension reduction, inhibition of connective tissue hyperplasia, and alleviation of skin inflammation, as well as the clinical application of BTX-A in treating different types of scars. However, at present there is no uniform standard for the time, method, and proportioning of BTX-A injection for scar treatment, and there is also a lack of long-term follow-up results. Further researches are needed in future to clarify the mechanism of BTX-A in inhibiting scars, establish a uniform protocol of BTX-A injection, and provide a more effective treatment plan for scars.

Abstract
Objective: To investigate the epidemiological characteristics and etiological distribution of infection on 3 067 hospitalized pediatric patients with burns, and explore the prevention and treatment strategy of pediatric burns. Methods: A cross-sectional survey was conducted. An analysis was performed on the data of 3 067 hospitalized pediatric patients with burns who met the inclusion criteria and were admitted to the First Affiliated Hospital of Army Medical University (the Third Military Medical University) from January 2012 to December 2020, including gender, age, causative factors, locations and severities of burns, seasons of accidents, and the type, source of tissue or body fluid, and drug resistance of pathogenic bacteria. API bacterial identification batten and automatic microbial identification system were applied for pathogen identification. Drug sensitivities of top 3 consistent ratio pathogen identifed were tested with minimum inhibitory concentration and disk diffusion method. WHONET 5.6 software was applied to analyze the data. Results: There were 3 067 hospitalized pediatric patients with burns, including 1 768 boys and 1 299 girls. The majority of pediatric burn patients were >1 and ≤4 years, accounting for 72.9% (2 236/3 067), and the minority of pediatric burn patients were >8 and ≤12 years, accounting for 4.9% (150/3 067). Moderate burns and severe burns of pediatric burn patients accounted for the majority parts, and the proportions of the two were close. The top cause of pediatric burns was scald, accounting for 81.6% (2504/3 067). Extremities were the most common burn sites in that of entire 3 254. The most pediatric burns occurred in winter, accounting for 29.4% (903/3 067). A total of 1 018 strains of pathogenic bacteria were collected from pediatric burn patients, all of which were non-repeated isolates. The pathogens with top five consistent ratio were Staphylococcus aureus, Pseudomonas aeruginosa, Acinetobacter baumannii, Enterobacter cloacae, and Escherichia coli, among which Staphylococcus aureus ranked the first every year. The pathogens were mainly isolated from the wound exudate, accounting for 81.34% (828/1 018). Staphylococcus aureus from 2012 to 2020 showed no resistance to vancomycin, linezolid or teicoplanin while Staphylococcus aureus isolated in 2019 was 100% resistant to macrolides, penicillin, aminoglycosides, and quinolones. Pseudomonas aeruginosa was not resistant to polymyxin B. Acinetobacter baumannii showed a high rate of drug resistance to most antibiotics. Conclusions: Among the pediatric burn patients admitted to the First Affiliated Hospital of Army Medical University (the Third Military Medical University) from 2012 to 2020, the majority are male children aged >1 and ≤4 years with moderate burns. Scalds are the leading cause; and extremities are the common burn sites; and the most pediatric burns occurre in winter. Staphylococcus aureus from wound exudate is the primary pathogen of burn wound infections in pediatric patients.

Abstract
Chronic obstructive pulmonary disease (COPD) represents a chronic inflammatory disorder of the airways induced mainly by cigarette smoking. In the current study, cigarette smoke extract (CSE) was used to develop an in vitro COPD model using human bronchial epithelium (HBE) cells to expound the possible role of microRNA-29b (miR-29b) in COPD. Firstly, miR-29b and interleukin (IL)-22 expression was assessed in serum of 20 healthy non-smokers, 20 healthy smokers and 20 COPD patients as well as CSE-treated HBE cells. Then, miR-29b and IL-22 expression was altered to evaluate their functions in Th17/Treg ratio. miR-29b inhibited Th17/Treg ratio and levels of IL-22; whereas overexpression of IL-22 reversed these trends. Moreover, rescue experiments found that IL-22 neutralized the repressive effects of miR-29b on Th17/Treg ratio and inflammatory response. Finally, we found that miR-29b blocked the JAK/STAT3 pathway in CSE-treated HBE cells. These data highlighted that miR-29bs modulated Th17/Treg imbalance in CSE-induced experimental COPD through inhibition of IL-22-dependent JAK/STAT3 pathway.

Abstract
Objective: To analyze the clinical characteristics of HBV-related liver cirrhotic patients with low viral load. Methods: A retrospective analysis on 481 inpatients with HBV-related cirrhosis with low viral load [HBV DNA≤2 000 IU/ml (10(4) copies/ml)] general condition, virological indicators, liver function-related indicators, complications, and incidence of complications were analyzed. The t-test was used to compare the average measurement data, and the χ (2) test was used to compare the count data. Results: 481 cases were mainly male (male/female: 324/157), aged 20-83 (53.31 ± 11.67) years old. Han nationality accounted for 71.518%. 386 cases were HBsAg positive. 391 cases were HBeAg positive, and 140 cases were HBV DNA positive. The average value of bilirubin, albumin, alanine aminotransferase, aspartate aminotransferase, platelets, and prothrombin were 50.59 ± 91.25 (μmol/L), 33.68 ± 7.5 (g/L), and 60.66 ± 106.95(U/L), 63.37 ± 86.19(U/L), 106.65 ± 83.22(×10(9)/L), 68.82% ± 25.33%, respectively. CTP class A/B/C had 220/150/111 cases. The average values of CTP, MELD, APRI and FIB-4 were 7.61 ± 2.58, 10.98 ± 5.79, 2.34 ± 3.56, 6.91 ± 8.04, respectively. The overall incidence of complications in HBV-related cirrhotic patients with low viral load, HBV DNA negative, HBV DNA positive, HBsAg negative, and HBsAg positive were 80.0%, 82.7%, 73.6%, 85.3%, and 78.8%, respectively. Among them, 283 cases (58.84%), 197 cases (55.77%), 86 cases (61.43%), 52 cases (54.74%) and 231 cases (59.84%) were of hypersplenism, and 267 cases (55.51%), 197 cases (55.77%), 70 cases (50.00%), 56 cases (58.95%), and 211 cases (54.66%) were of esophagogastric varices. There were 59 cases (12.27%), 48 cases (14.08%), 11 cases (7.86%), 12 cases (12.63%), and 47 cases (12.18%) of rupture of esophageal and gastric varices, respectively. 202 cases (42.00%), 147 cases (43.11%), 55 cases (39.29%), 42 cases (44.21%), and 160 cases (41.45%) were of ascites, respectively. 17 cases (3.53%), 12 cases (3.52%), 5 cases (3.5%), 2 cases (2.11%), 15 (3.89%) cases were of hepatic encephalopathy, respectively. There were 6 cases (1.25%), 3 cases (0.88%), 3 cases (2.14%), 0 cases (0%), 6 cases (1.55%) of liver cancer. 29 cases (6.03%), 21 cases (6.16%), 8 cases (5.71%), 9 cases (9.47%) and 20 cases (5.18%) were of portal vein thrombosis. Compared with the overall incidence of complications, 341 HBV DNA-negative patients and 95 HBsAg-negative patients still had higher incidence of complications. The patients were grouped by age, and in < 40 years old, 40-50 years old, and > 50 years old, the overall complications were 80.8% in 42 cases, 76.8% in 116 cases and 81.7% in 227 cases, and the difference was not statistically significant. Conclusion: HBV infection patients with low viral load, and those whose HBsAg has disappeared, are still at risk of developing liver cirrhosis and even serious complications, and whether such population need antiviral therapy and benefit from it deserves further research.

Abstract
Objective: To study the thickness of cervical squamous epithelia and its correlation with cervical precancerous lesions. Methods: We selected 495 HE slides of 209 cervical biopsies from January 2020 to June 2020 in the Department of Pathology, the First and Seventh Medical Center of the PLA General Hospital, including 173 slides with low grade squamous intraepithelial lesion (LSIL) and 214 slides with high grade squamous intraepithelial lesion (HSIL). Artificial intelligence labeling software was used to assist in measuring the epithelial thickness of normal cervical squamous epithelium, LSIL and HSIL of each slide. The thickest, thinnest, and middle widths of epithelial thickness were measured, respectively. Average epithelial thickness was defined as the sum of the above three widths divided by 3. The correlation statistical analysis was performed by combining the data of age and pathological diagnosis. Results: The average thickness of normal cervical squamous mucosa was (245.83±91.40) μm, which was (222.42±81.22) μm and was (195.95±66.59) μm in LSIL and HISL epithelial respectively (F=27.09, P<0.01). The average cell layers of normal cervical squamous epithelium was (15.5±4.2) layers, which of LSIL was (14.8±4.8) layers, and that of HSIL was (15.8±4.8) layers. The differences among normal, LSIL and HSIL were not statistically significant (P>0.05). Further statistical analysis was stratified by age (≤30 years, 31-40 years, 41-50 years, 51-60 years, and >60 years), the results of Pearson correlation analysis showed that the thickness of normal cervical squamous epithelial gradually thinned with age (correlation coefficient r=-0.141 9, P<0.05), while LSIL and HSIL epithelial thickness had significant correlation with age (P>0.05). In the subgroup of ≤50 years old, the epithelial thickness of normal squamous epithelium was the thickest, followed by LSIL, and HSIL epithelial thickness was the thinnest. The differences were statistically significant (P<0.05). While in the subgroup of >50 years, the differences were not statistically significant (P>0.05). Conclusions: The cervical squamous epithelium gradually becomes thinner with the degree of precancerous lesions increasing among patients of ≤50 years old. However, after age of 50 years, with the onset of menopause, the normal mucosal epithelium is becoming atrophy, so that mucosal thickness is no longer correlated with the extent of the lesion. In addition, it is suggested that the cervical vinegar white test performance during colposcopy is related to the protein changes in the mucosal epithelial cells, but not directly related to the thickness of the epithelial layer.

Abstract
BACKGROUND AND PURPOSE Small intracranial aneurysms are being increasingly detected while the rupture risk is not well-understood. We aimed to develop rupture-risk models of small aneurysms by combining clinical, morphologic, and hemodynamic information based on machine learning techniques and to test the models in external validation datasets. MATERIALS AND METHODS From January 2010 to December 2016, five hundred four consecutive patients with only small aneurysms (<5 mm) detected by CTA and invasive cerebral angiography (or surgery) were retrospectively enrolled and randomly split into training (81%) and internal validation (19%) sets to derive and validate the proposed machine learning models (support vector machine, random forest, logistic regression, and multilayer perceptron). Hemodynamic parameters were obtained using computational fluid dynamics simulation. External validation was performed in other hospitals to test the models. RESULTS The support vector machine performed the best with areas under the curve of 0.88 (95% CI, 0.85-0.92) and 0.91 (95% CI, 0.74-0.98) in the training and internal validation datasets, respectively. Feature ranks suggested hemodynamic parameters, including stable flow pattern, concentrated inflow streams, and a small (<50%) flow-impingement zone, and the oscillatory shear index coefficient of variation, were the best predictors of aneurysm rupture. The support vector machine showed an area under the curve of 0.82 (95% CI, 0.69-0.94) in the external validation dataset, and no significant difference was found for the areas under the curve between internal and external validation datasets (P = .21). CONCLUSIONS This study revealed that machine learning had a good performance in predicting the rupture status of small aneurysms in both internal and external datasets. Aneurysm hemodynamic parameters were regarded as the most important predictors.

Abstract
Objective: To evaluate the feasibility and safety of right ventricular endomyocardial biopsy (EMB) via the right internal jugular vein approach. Methods: It was a retrospective and descriptive study. A total of 272 patients, who underwent right ventricular EMB from December 2014 to June 2020 in Fuwai Hospital and Peking Union Medical College Hospital were enrolled. The preliminary diagnosis included suspected myocarditis, myocardiopathy, unexplained heart failure etc after exclusion of coronary heart disease. Clinical characteristics including age, sex, height, weight, NYHA functional class, NT-proBNP, chest radiography, echocardiography, and hemodynamics parameters were collected at baseline. EMB was performed via right internal jugular vein approach under the biplane fluoroscopic guidance. Success rate was calculated in this study. Complications related to operation were recorded according the following definitions. Major complications included death, urgent cardiac surgery, advanced cardiac life support, pericardiocentesis in cardiac tamponade, permanent complete atrioventricular block requiring permanent pacing etc. Minor complications included pericardial effusion without pericardiocentesis, temporary (lasting less than 24 hours) or permanent right bundle-branch block, temporary Mobitz type Ⅱ atrioventricular block (AV block) with AV conduction 2∶1 requiring medical treatment with atropine, or additive temporary pacing, non-sustained ventricular tachycardia with long runs of more than 10 ventricular complexes, and an episode of atrial fibrillation lasting less than 12 hours or cardioversion of atrial fibrillation. Other complications included tricuspid anterior chorda rupture and new onset tricuspid regurgitation after EMB. Results: In this study, right ventricular EMB were performed successfully in 270 patients, the total success rate was 99.3% (270/272), and EMB were failed in 2 (0.7%) patients. Age of the enrolled patients was (42.7±16.9) years, and there were 164 (60.3%) males. Major complication including cardiac tamponade requiring pericardiocentesis occurred in 2 (0.7%) patients. Minor complications such as small amount pericardial effusion occurred in 18 (6.6%) patients, tricuspid anterior chorda rupture occurred in 1 (0.4%) patient. No patient died, or requiring permanent pacing, or requiring emergency cardiac surgery. The complication rate was 9.3% (13/140), 7.8% (7/90), and 2.4% (1/42) in operators with 1, 2, and 3 years' experience. Conclusions: EMB via the right jugular vein approach under fluoroscopic guidance is a simple, safe and feasible procedure. The complication rates decrease significantly with increasing operator experience.

Abstract
Objective: To analysis the clinical characteristics of"recurrence"RNA positive patients with Coronavirus disease 2019 (COVID-19) and compared with those without"recurrence". Methods: 98 patients with COVID-19 in Wuhan Jinyintan Hospital and designated treatment hospitals in Quanzhou were included in this study from February 2020 to April 2020. There were 55 males and 43 females, aged from15 to 83 years, with a median age of 57.5 years, in which 20 cases were complicated with basic diseases. 15 of these patients had been diagnosed and hospitalized had been found as"recurrence"2019-nCoV RNA positive after discharge while the other 83 cases were all negative. The clinical classification of all patients was common type. Clinical data of the COVID-19 RNA"recurrence"patients were collected, and general situations, symptoms, laboratory examinations and CT images were also observed and analyzed. The patients were divided into 2019-nCoV"recurrent"group and 2019-nCoV"non-recurrent"group. There are 10 males and 5 females in 2019-nCoV"recurrent"group while 45 males and 38 females in"non-recurrent"group (χ²=0.800,P=0.371). The age of 2019-nCoV"recurrent"group (57±21) was higher than that of"non-recurrent"group(53±17). 8 of 15 the COVID-19"recurrent"group patients and 12 of 83"non-recurrent"patients have basic diseases. IgG and IgM of 2019-nCoV, IL-6, procalcitonin, ESR, CRP, BNP and other serum biochemical index levels were measured and compared between groups. Results: (1) The proportion of patients with common type of COVID-19 was 15.3% during 2-week medical observation after discharge. (2) All of the 2019-nCoV"recurrent"patients were hospitalized due to COVID-19 RNA positive, when they were quarantined after discharged from hospital. All the patients with mild symptoms which were clarified as common type, including 5 cases of fever, 6 cases of cough, 5 cases of expectoration, and 2 cases of slight shortness of breath. The time of symptoms appeared on (5.73±2.82) days after discharge. (3) The serum procalcitonin of all 2019-nCoV"recurrent"group patients were normal(all<0.05 ng/ml). The BNP of"recurrent"group (151±171) ng/L, was higher than that of"non-recurrent"group (63±78) ng/L (t = 3.207, P = 0.000). There was no significant difference in laboratory tests like leukocyte [(6.17±2.4) and (6.04±2.41)×109/L], lymphocyte[(1.59±0.52) and (1.32±0.64)×109/L], CRP [(12.54±28.20) and (21.74±25.63)mg/L], ESR [(31.07±28.72) and (34.10±22.16)mm/1 h], AST [(24.73±9.15) and (30.24±23.20)U/L], ALT [(22.60±12.82) and (36.47±34.12)U/L), LDH [(268±208) and (270±164)U/L], D-dimer [(0.60±0.50) and (0.84±0.98)μg/L], ferritin [(294±195) and (395±319)μg/L], IL-6 [(9.17±6.42) and (14.28±17.74)ng/L] and BUN (5.77±2.66) and (4.74±2.81)U/L] between"recurrent"and"non-recurrent"groups (all P>0.05). (4) In"recurrent"group, ground glass, exudative or solid lesions could be found in most of the chest CT performed on re-admission. Meanwhile, fibrosis lesion was relatively rare. (5) There were no secondary transmissions were found to be caused by the 2019-nCoV"recurrent"group patients. Conclusions: Most of the 2019-nCoV patients had underlying diseases and active lesions were still found in CT images, so the possibility of virus replication may still exist. All"recurrent"patients had mild illness which may suggest that they were in recovery stage, and no evidence of transmission is found.

Abstract
On April 11, 2019, a 36-year-old female patient was admitted to Hunan Cancer Hospital. Five years after the modified radical mastectomy for right breast cancer, she planned to undergo scar releasing and reconstruction of right chest wall and free deep inferior epigastric artery perforator (DIEP) flap transfer, right breast reconstruction, and left breast mastopexy. The defect of right chest wall after scar resection was 18 cm×10 cm. During the operation, the vascular pedicle of DIEP flap was accidentally injured, then the profunda artery perforator flap in left inner thigh was designed for salvage. The size of the flap was 20 cm×11 cm, the thickness was 4.5 cm, the length of perforator vessel pedicle was 7.6 cm, and the weight of the flap was 360 g. The right breast defect was repaired with the transferred flap and the deep cavity was filled. The vascular pedicle of profunda artery was anastomosed with the proximal end of the right internal mammary artery. The blood supply of the flap was good during surgery. The left breast mastopexy was completed at the same time, and the donor site of thigh and abdomen was closed directly. The flap survived well and the donor site healed well after surgery. During the follow-up of 7 months post surgery, the appearance and function of thigh donor site were good, no obvious complications were found, and the reconstructed breast was smaller than the contralateral side. This case suggests that the profunda artery perforator flap could be a valuable option as an alternative for DIEP harvesting failure for autologous breast reconstruction.

Abstract
Hallux valgus is a common foot deformity disease caused by various extrinsic and intrinsic factors, and systemic conditions, but the etiopathogenesis and pathogenesis of this deformity are still unknown. Hallux valgus affects 10-20% of Chinese adults. Although considered highly heritable, the candidate gene is unclear. We conducted the first candidate gene study of hallux valgus to identify the biological mechanism. Between June 2015 and July 2018, the records and radiographs of 80 patients diagnosed with hallux valgus and 80 controls who were treated were analyzed. In order to compare the differences in severity associated with this deformity, the charts of 80 patients were divided into 3 groups from the angle of hallux valgus. Clinical and basic studies were also statistically compared by PCR and data analysis. Patients and controls had significant differences in age and gender, however, there were no significant differences in age and gender among the light, moderate and severe groups. Post-operative groups resulted in significant improvements in all of the measured radiographic parameters compared with pre-operative groups. BsmI seemed to show a specific variation, and may serve as a useful bio-marker for the disease (OR = 5.88, 95% CI 1.54-22.35, P <0.001). In this paper, the article which proved the VDR polymorphisms (BsmI) playing an important role in hallux valgus were studied to understand and manage the hallux valgus more scientifically.

Abstract
Searches for electron antineutrino, muon neutrino, and muon antineutrino disappearance driven by sterile neutrino mixing have been carried out by the Daya Bay and MINOS+ collaborations. This Letter presents the combined results of these searches, along with exclusion results from the Bugey-3 reactor experiment, framed in a minimally extended four-neutrino scenario. Significantly improved constraints on the θ_{μe} mixing angle are derived that constitute the most constraining limits to date over five orders of magnitude in the mass-squared splitting Δm_{41}^{2}, excluding the 90% C.L. sterile-neutrino parameter space allowed by the LSND and MiniBooNE observations at 90% CL_{s} for Δm_{41}^{2}<13 eV^{2}. Furthermore, the LSND and MiniBooNE 99% C.L. allowed regions are excluded at 99% CL_{s} for Δm_{41}^{2}<1.6 eV^{2}.

Abstract
AIMS To obtain the high-yield strain of fusidic acid, which is produced from fungus Fusidium coccineum and is the only fusidane-type antibiotic that has been used clinically, and confirm the changes in the transcription levels involved in increasing its production. METHODS AND RESULTS By using the atmospheric and room temperature plasma mutagenesis technology, a high-yield mutant strain of fusidic acid-producing fungus F. coccineum was obtained. Using the genomic analysis of the original strain based on biosynthetic pathways of ergosterol and helvolic acid, we demonstrate that the pathway involved in the biosynthesis of 2,3-oxidosqualene from acetyl coenzyme A was shared by fusidic acid and ergosterol, and fusidic acid was finally synthesized by the catalysis of multiple cytochrome P450s and short-chain dehydrogenase/reductase from 2,3-oxidosqualene. Then, through the transcriptomic analysis of the original and mutagenized strain, it revealed that the proposed pathway from sucrose to fusidic acid was the most significantly up-regulated in the transcription levels of the mutant strain. CONCLUSIONS The changes in the transcription levels of fusidic acid during its biosynthesis might result in high-yield of fusidic acid in the mutant strain. This is the first report on the whole biosynthetic pathway of fusidic acid in F. coccineum. SIGNIFICANCE AND IMPACT OF THE STUDY This study obtain the genetic basis for the biosynthesis of fusidic acid which could be beneficial for the molecular modifications of F. coccineum to further increase its yield by fermentation in future, and established the foundation to reveal the mechanism of the high-yield of the mutant strain.

Abstract
Objective To establish a rapid diagnosis method for the biological toxicity of soil, accurately and rapidly evaluate the toxicity of contaminated sites and identify the dominant pollutants. Methods Take the soil pollution of a galvanized factory as an example, while the metal concentration level was analyzed and detected, a rapid biological toxicity detection method based on the acute toxicity test of luminescent bacteria (Vibrio qinghaiensis sp.-Q67) was established, and the dominant pollutants were identified by stepwise multiple regression. Results The pollutants came from wastewater and metal plating fragments directly discharged from the manufacturing line of the factory. The concentration of those pollutants was correlated with the acute toxicity of Vibrio qinghaiensis sp.-Q67. The dominant pollutants in the study were zinc (Zn), aluminum (Al) and copper (Cu). Conclusion The luminescent bacteria toxicity test method based on Vibrio qinghaiensis sp.-Q67 can conveniently and rapidly assess the degree of toxic damage of polluted soil and identify the dominant pollutants and can be applied to the acute toxicity evaluation of polluted soil.

Abstract
Objective: To explore the clinical effect of free transplantation of thoracodorsal artery perforator flap in reconstructing large scar on the facial subunit. Methods: From April 2014 to March 2018, 7 patients with large facial scar were admitted to Ningbo NO.6 Hospital, including 3 males and 4 females, aged from 31 to 49 years, 4 with frontal involvement and 3 with chin and neck. Color Doppler ultrasound was used for the positioning of the thoracodorsal artery perforating vessel, and scar resection was performed according to the principle of facial subunit repair. The wound area was 8 cm×6 cm-21 cm×8 cm, and the wound was repaired with the free thoracodorsal artery perforator flap in the area of 9 cm×7 cm-22 cm×9 cm. The donor site was closed directly by suturing. The consistency of the location of the perforating vessel explored during the operation with its preoperative positioning and the flap survival were recorded. The color, texture, and appearance of the flap and the healing condition, scar formation, and function of the donor area were observed during follow-up. Results: The locations of the perforating vessels of 7 patients explored during the operation were consistent with those positioned by color Doppler ultrasound before the operation. All the flaps of the 7 cases survived successfully after operation. Postoperative follow-up of 12-18 months showed that the flap color was similar to the surrounding skin of the recipient area, with soft texture and no obvious contracture. Slight bloated appearance was observed in the flaps of 4 cases. All the 7 patients had postoperative healing of the flap donor site without obvious scar hyperplasia or influence on shoulder joint function. Conclusions: The anatomy of the perforating vessel of the thoracodorsal artery perforator flap is relatively constant and the flap can be cut in large area with soft texture, good appearance, and concealed donor area, which is a good choice for reconstructing large scar on the facial subunit.

Abstract
Objective: To explore the selection and effects of flap/myocutaneous flap repair methods for the defect after perineum tumor resection. Methods: From January 2011 to February 2017, 31 patients with vulvar tumor who were admitted to Hunan Cancer Hospital underwent repair of wound after tumor resection with various flaps/myocutaneous flaps. The patients were composed of 5 males and 26 females, aged 39-76 years, with 27 vulvar cancer and 4 Paget's disease in primary diseases. The size of defects after vulvar tumor radical resection ranged from 8.0 cm×4.5 cm to 27.5 cm×24.0 cm. According to the theory of perforasome, the defects were repaired by the external pudendal artery perforator flap, deep inferior epigastric artery perforator flap, rectus abdominis myocutaneous flap, anterolateral thigh flap, internal pudendal artery perforator flap, gracilis myocutaneous flap, and profunda artery perforator flap based on the specific size and location of perineum and groin where the defect was located. According to the blood supply zone of flap, totally 17 local translocation flaps, 18 axial flaps/myocutaneous flaps, and 7 V-Y advancement flaps were resected, with an area of 7.0 cm×4.0 cm to 21.0 cm×13.0 cm. All the flaps/myocutaneous flaps were transferred in pedicled fashion, and the donor sites were closed without tension. The number of flaps/myocutaneous flaps, wound closure, flaps/myocutaneous flaps survival, and follow-up were observed and recorded. Results: Altogether 42 flaps/myocutaneous flaps were harvested in 31 patients. Two flaps/myocutaneous flaps were used in 11 cases for large circular defect repair. All the defects achieved tension-free primary closure. The blood supply of 32 flaps/myocutaneous flaps was good, while insufficient blood supply was noted in the other 10 flaps/myocutaneous flaps. Seventeen flaps/myocutaneous flaps survived smoothly. Wound dehiscence occurred in 5 flaps/myocutaneous flaps 8 to 14 days postoperatively, which was healed with dressing change. Temporary congestion was noted in 7 flaps/myocutaneous flaps 2 to 5 days postoperatively, which recovered without special treatment. Three flaps/myocutaneous flaps had infection 7 to 15 days postoperatively, two of which recovered after dressing change, while the other one had partial necrosis and received debridement and direct closure. Two flaps/myocutaneous flaps were totally necrotic 8 to 15 days postoperatively, which were repaired with pedicled rectus abdominis myocutaneous flap after debridement. Seven flaps/myocutaneous flaps had partial necrosis 7 to 20 days postoperatively and were healed after dressing change. Twenty-four patients were followed up for 9-38 months. The color of flaps/myocutaneous flaps was similar to that of the surrounding skin, the shape of vulva was natural, the movement of hip joint was not limited, the function of micturition and defecation was not affected, and tumor recurrence was noted in 3 patients. Conclusions: For the complicated large defect after perineum tumor resection, the flexible application of different forms of flaps/myocutaneous flaps to repair according to different areas regains the appearance and function. However, there are many complications, so it is necessary to further strengthen the postoperative care.

Abstract
Objective: To investigate the clinical effect of Zhang's super tension-relieving suture applied in high-tension wound closure. Methods: From January to August 2019, 19 eligible patients with scar or black hairy nevus were treated with Zhang's super tension-relieving suture for outpatient operation in the Department of Plastic and Reconstructive Surgery of Shanghai Ninth People's Hospital Affiliated to Shanghai Jiao Tong University School of Medicine. The patients were composed of 6 males and 13 females, aged 10-68 years, with 8 keloids, 3 hypertrophic scars, 5 atrophic scars, and 3 black hairy nevus. The operation sites included lower jaw in 2 cases, neck in 3 cases, chest in 4 cases, abdomen in 2 cases, and limbs in 8 cases. The size of scars and black hairy nevus before surgery ranged from 1.4 cm×1.1 cm to 10.0 cm×4.0 cm. All the lesions underwent excision alone with both sides of the incision undermined for 1 to 2 cm, and the wound size ranged from 2.6 cm×2.6 cm to 12.6 cm×6.8 cm. Zhang's super tension-relieving suture was applied with barbed suture, and the wound edges were naturally jointed with relaxation and low tension by pushing normal skin on both sides to the middle. Two patients with keloids underwent superficial radiotherapy within 24-hour interval after the surgery, with a total of 20 Gy delivered in 4 times, once a day. All the patients were followed up at outpatient clinics, with tension-relieving duration and adverse effects recorded. Six months after operation, the Vancouver Scar Scale (VSS) was used to evaluate scar appearance, while scar width and recurrence were recorded. Results: All the wounds of 19 patients healed completely after surgeries. Two patients experienced transient hyperpigmentation at puncture points and recovered without intervention, and one of them had hypertrophic scar at the puncture point, which was relieved after intralesional injections of corticosteroids. One patient underwent transient erythema, dry desquamation, and hyperpigmentation after radiotherapy, which recovered without intervention. Follow-up time ranged from 7.1 to 13.6 months, with an average of 9.6 months. Tension-relieving duration ranged from 4 to 26 weeks, with an average of 11.2 weeks. Two patients underwent Zhang's super tension-relieving suture again 8 weeks after operation due to their short tension-relieving duration which lasted for only 4 weeks after the first suture. Six months after operation, liner scars were achieved in all the patients with an average width of 2.2 mm (0.8 to 7.0 mm) and an average VSS score of 2.1 points (1.0 to 4.3 points). Three keloid patients had local recurrence 3 months after surgery for not receiving radiotherapy, which was obviously relieved following laser treatment in combination with intralesional injections of corticosteroids and 5-fluorouracil, etc. Conclusions: Zhang's super tension-relieving suture technique with barbed suture is able to effectively relieve the tension on wound edges, extend the tension-relieving duration, and reduce the hypertrophic scar risk when applied in high-tension wound.
