Abstract
Probiotics exert beneficial effects by regulating the intestinal microbiota, metabolism, immune function and other ways of their host. Patients with constipation, a common gastrointestinal disorder, experience disturbances in their intestinal microbiota. In the present study, we investigated the effectiveness of two microbial ecological agents (postbiotic extract PE0401 and a combination of postbiotic extract PE0401 and Lacticaseibacillus paracasei CCFM 2711) in regulating the makeup of the intestinal microbiota and alleviating loperamide hydrochloride-induced constipation in mice. We also preliminarily explored the mechanism underlying their effects. Both microbial ecological agents increased the abundance of the beneficial bacteria Lactobacilli and Bifidobacterium after administration and were able to relieve constipation. However, the degree of improvement in constipation symptoms varied depending on the makeup of the supplement. The postbiotic extract PE0401 increased peristalsis time and improved faecal properties throughout the intestinal tract of the host. PE0401 relieved constipation, possibly by modulating the levels of the constipation-related gastrointestinal regulatory transmitters mouse motilin, mouse vasoactive intestinal peptide, and 5-hydoxytryptamine in the intestinal tract of the host and by increasing the levels of the short-chain fatty acids (SCFAs) acetic acid, propionic acid, and isovaleric acid. It also increased the relative abundance of Lactobacillus and Bifidobacterium and reduced that of Faecalibaculum, Mucispirillum, Staphylococcus, and Lachnoclostridium, which are among the beneficial microbiota in the host intestine. Furthermore, PE0401 decreased the levels of constipation-induced host inflammatory factors. Therefore, the two microbial ecological agents can regulate the intestinal microbiota of constipation mice, and PE0401 has a stronger ability to relieve constipation.

Abstract
OBJECTIVE To investigate the microbiota composition and diversity between autogenous and anautogenous Culex pipiens pallens, so as to provide insights into unraveling the pathogenesis of autogeny in Cx. pipiens pallens. METHODS Autogenous and anautogenous adult Cx. pipiens pallens samples were collected at 25 ℃, and the hypervariable regions of the microbial 16S ribosomal RNA (16S rRNA) gene was sequenced on the Illumina NovaSeq 6000 sequencing platform. The microbiota abundance and diversity were evaluated using the alpha diversity index, and the difference in the microbiota structure was examined using the beta diversity index. The microbiota with significant differences in the abundance between autogenous and anautogenous adult Cx. pipiens pallens samples was identified using the linear discriminant analysis effect size (LEfSe). RESULTS The microbiota in autogenous and anautogenous Cx. pipiens pallens samples belonged to 18 phyla, 28 classes, 70 orders, 113 families, and 170 genera, and the dominant phyla included Proteobacteria, Bacteroidetes, and so on. At the genus level, Wolbachia was a common dominant genus, and the relative abundance was (77.6 ± 11.3)% in autogenous Cx. pipiens pallens samples and (47.5 ± 8.5)% in anautogenous mosquito samples, while Faecalibaculum (0.4% ± 0.1%), Dubosiella (0.5% ± 0.0%) and Massilia (0.5% ± 0.1%) were specific species in autogenous Cx. pipiens pallens samples. Alpha diversity analysis showed that higher Chao1 index and ACE index in autogenous Cx. pipiens pallens samples than in anautogenous samples (both P values > 0.05), and lower Shannon index (P > 0.05) and Simpson index (P < 0.05) in autogenous Cx. pipiens pallens samples than in anautogenous samples. LEfSe analysis showed a total of 48 significantly different taxa between autogenous and anautogenous Cx. pipiens pallens samples (all P values < 0.05). CONCLUSIONS There is a significant difference in the microbiota diversity between autogenous and anautogenous Cx. pipiens pallens.

Abstract
BACKGROUND Inguinal hernia is a relatively common condition. Most patients with inguinal hernia require surgery. At present, mesh repair is one of the most effective methods to treat inguinal hernia, but insertion of the mesh can cause inflammation. Dexamethasone (DEX) can treat inflammation, but the mechanism by which DEX alleviates inflammation caused by inguinal hernia mesh placement remains unclear. METHOD We randomly divided rats into groups: negative control (NC), inguinal hernia (IH), polypropylene mesh (PM), DEX treatment, and miR-155 treatment groups. RT-qPCR was performed to determine the expression of miR-155. ELISA was implemented to determine the secretion of IL-1β, IL-6, and IL-18. Western blotting was used to detect caspase-1, JAK1, p-JAK1, STAT3, and p-STAT3 expression. A dual-luciferase reporter gene array identified a connection between miR-155 and JAK1. RESULTS The results revealed that the expression of miR-155, IL-1β, IL-6, and IL-18 was upregulated in the PM group. After DEX treatment, the secretion of miR-155, caspase-1, IL-1β, IL-6, and IL-18 decreased. Dual luciferase results confirmed that miR-155 induced the targeted downregulation of JAK1, while a miR-155 mimic reversed the therapeutic effect of DEX, and the expression levels of p-JAK1 and p-STAT3 increased. CONCLUSION DEX regulates the JAK1/STAT3 signaling pathway through miR-155 to relieve inflammation caused by inguinal hernia meshes.

Abstract
BACKGROUND Hyaluronic acid (HA) is a widely used filler for face contouring and is generally believed to be safe and effective. However, there have been reports of HA-related bone erosion in the chin area without clear scientific data regarding its existence, incidence, and severity. This exploratory study was to evaluate HA-related mental bone resorption through a prospective, controlled, observer-blind, nonrandomized clinical trial and a retrospective cohort study. METHODS On the one hand, a prospective, controlled, nonrandomized, single-shot HA-injection clinical trial was conducted. Computed tomographic scans were collected at baseline and at 6-12 months of follow-up for both HA-injection and control groups. On the other hand, an updated retrospective cohort study compared the HA-injection with a blank control group. The primary outcomes composed of three quantitative parameters [bone resorption index (BRI M and BRI N ), bone resorption thickness ratio] and one subjective evaluation index (severity ranking). Information about demographics, complications, and injection volume were also recorded. RESULTS From June 2021 to March 2023, 78 patients were prospectively recruited for the study. There was a significant association between HA-injection and bone resorption [BRI M : pre (84.24±8.10%) vs post (79.21±8.70%), P <0.001; BRI N : pre 92.50% (73, 144%) vs 87.99% (63, 132%), P <0.001; bone thickness ratio: HA 24.08% (0, 48%) vs control 0 (0, 17%), P <0.001]. However, there was no difference in large-volume (>1 ml) and small-volume (≦1 ml) injection subgroups [bone resorption thickness ratio: (21.50±10.91%) vs (24.51±11.92%), P =0.350]. The imaging manifestation revealed discernible bone resorption in 35.90% of the patients, with an median bone resorption thickness ratio of 24.08%. Between October of 2019 and March 2023, 95 HA-injection patients (190 semimandibular cases), 95 normal controls were enrolled. The BRI M was significantly lower in the HA-injection group compared to the controls ( P <0.001). CONCLUSIONS HA may induce bone resorption in the mentum. Large-scale randomized controlled clinical trial is warranted for further confirmation. Patients should be informed of this potential complication.

Abstract
Objective: In this study, we aimed to compare the short-term safety of two digestive tract reconstruction techniques, laparoscopic total abdominal overlap anastomosis and laparoscopic-assisted end-to-side anastomosis, following radical resection of Siewert Type II adenocarcinoma of the esophagogastric junction. Methods: In this retrospective cohort study, we analyzed relevant clinical data of 139 patients who had undergone radical surgery for Siewert Type II esophagogastric junction adenocarcinoma. These included 89 patients treated at the First Affiliated Hospital of Air Force Medical University from November 2021 to July 2023, 36 patients treated at the First Affiliated Hospital of Xi'an Jiaotong University from December 2020 to June 2021, and 14 patients treated at the Yuncheng Central Hospital in Shanxi Province from September 2021 to November 2022. The group consisted of 107 men (77.0%) and 32 women (23.0%) of mean age 62.5±9.3 years. Forty-eight patients underwent laparoscopic total abdominal overlap anastomosis (overlap group), and 91 laparoscopic-assisted end-to-side anastomosis (end-to-side group). Clinical data, surgical information, pathological findings, postoperative recovery, and related complications were compared between the two groups. Results: There were no significant differences in general clinical data between the overlap and end-to-side anastomosis groups (all P>0.05), indicating comparability. There was no significant difference in operation time (267.2±60.1 minutes vs. 262.8±70.6 minutes, t=0.370, P=0.712). However, the intraoperative blood loss in the overlap group (100 [50, 100] mL) was significantly lower compared to the end-to-side group (100[50, 175] mL, Z=2.776, P=0.005). Compared to the end-to-side group, longer distances between the tumor and distal resection margin proximal(1.7±1.0 cm vs. 1.3±0.9 cm, t=2.487, P=0.014) and the tumor and distal resection margin (9.5±2.9 cm vs. 7.9±3.5 cm, t=2.667, P=0.009) were achieved in the overlap group. Compared with the end-to-side group, the overlap group achieved significantly earlier postoperative ambulation (1.0 [1.0, 2.0] days vs. 2.0 [1.0, 3.0] days, Z=3.117, P=0.002), earlier time to first drink (4.7±2.6 days vs. 6.2±3.0 days, t=2.851, P=0.005), and earlier time to first meal (6.0±2.7 days vs. 7.1±3.0 days, t=2.170, P=0.032). However, the hospitalization costs were higher in the overlap group (113, 105.5±37, 766.3) yuan vs. (97, 250.2±27, 746.9) yuan; this difference is significant (t=2.818, P=0.006). There were no significant differences between the two groups in postoperative hospital stay, total number of lymph nodes cleared, or time to first postoperative flatus (all P>0.05). The incidence of surgery-related complications was 22.9%(11/48) in the overlap group and 19.8% (18/91) in the end-to-side group; this difference is not significant (χ²=0.187, P=0.831). Further comparison of complications using the Clavien-Dindo classification also showed no significant differences (Z=0.406, P=0.685). Conclusions: Both laparoscopic total abdominal overlap anastomosis and laparoscopic-assisted end-to-side anastomosis are feasible for radical surgery for Siewert Type II esophagogastric junction adenocarcinoma. Laparoscopic total abdominal overlap anastomosis achieves longer proximal and distal resection margins and better postoperative recovery; however, end-to-side anastomosis is more cost-effective.

Abstract
Objective: To understand the status of human papillomavirus (HPV) infection among young women without a history of vaccination in Shanghai, and analyze the related factors of HPV infection in this population. Methods: A total of 2 660 women aged 18-24 years old who had made an appointment for HPV vaccine at 36 community health service centers in Shanghai from July 2022 to February 2023 were selected as the study subjects. Basic information (including demographic characteristics, previous disease history, female menstrual and reproductive history, sexual life history, etc.) was collected by a self-filling electronic questionnaire. Cervical secretions were detected by HPV nucleic acid typing. The multivariate logistic regression model was used to analyze the factors related to high-risk HPV (HR-HPV) infection in the target population. Results: The age of the subjects was (23±1) years old, and the infection rate of HPV was 14.51% (386 cases), among which the infection rates of HR-HPV and low-risk HPV were 13.53% (360 cases) and 1.84% (49 cases), respectively. The main subtypes of HR-HPV infection were HPV52, 16, 58, 39 and 66. The multivariate logistic regression model analysis showed that compared with the control group, the OR (95%CI) values for HR-HPV infection in the group of married, earned less than 2 000 yuan/month, drank alcohol occasionally, gynecological disease history, had two or more sexual partners in the past year, and did not know whether the partners had other sexual partners were 0.41 (0.25-0.66), 0.39 (0.21-0.70), 1.45 (1.13-1.86), 1.29 (1.00-1.66), 2.18-5.18 (1.02-16.05), and 1.82 (1.31-2.54), respectively. Conclusion: The infection rate of HPV among women aged 18-24 years old in Shanghai remains at a high level. The main subtypes of HR-HPV infection are HPV52, 16, 58, 39 and 66. The marital status, economic income level, drinking status, gynecological disease history and sexual life history are related to HR-HPV infection.

Abstract
To explore the influence of extracellular vesicles secreted by dural cells (Dura-EVs) on osteoblasts. Our methodology involves assessing the effects of these EVs at concentrations of 50ug/ml, 100ug/ml, and 200ug/ml on osteoblasts proliferation, differentiation, migration, osteogenesis, and inhibition of apoptosis. We also treated a cranial defect model with injections of these Dura-EVs and monitored the healing rate of cranial defects. Tissue sections were analyzed using Hematoxylin and Eosin (H & E), Masson's trichrome, and immunofluorescence (IF) staining. Our results suggest that Dura-EVs can enhance osteoblasts proliferation, migration, differentiation, and osteogenesis in a dose-dependent manner in vitro. In vivo, Dura-EVs may promote the repair of skull defects. Dura-EVs have an important influence on osteoblasts, our findings shed light on a novel aspect of the dura mater's contribution to cranial osteogenesis.

Abstract
Objective: To investigate the clinicopathological features of perivascular epithelioid cell tumor (PEComa) of the lung. Methods: Eight PEComa cases of the lung diagnosed at the First Affiliated Hospital of Soochow University, Suzhou, China from July 2008 to December 2021 were collected and subject to immunohistochemical staining, fluorescence in situ hybridization and next generation sequencing. The relevant literature was reviewed and the clinicopathological features were analyzed. Results: There were 5 males and 3 females, aged from 18 to 70 years (mean 39 years). There were 3 cases of the right upper lung, 3 cases of the left lower lung, 1 case of the left upper lung and 1 case of the right middle lung. Seven cases were solitary and 1 case was multifocal (4 lesions). Seven cases were benign while one was malignant. The tumors were all located in the peripheral part of the lung, with a maximum diameter of 0.2-4.0 cm. Grossly, they were oval and well circumscribed. Microscopically, the tumor cells were oval, short spindle-shaped, arranged in solid nests, acinar or hemangiopericytoma-like patterns, with clear or eosinophilic cytoplasm. The stroma was rich in blood vessels with hyalinization. Coagulated necrosis and high-grade nuclei were seen in the malignant case, and calcification was seen in 2 cases. Immunohistochemically, the tumor cells were positive for Melan A (8/8), HMB45 (7/8), CD34 (6/8), TFE3 (4/7), and SMA (3/8). All cases were negative for CKpan and S-100. TFE3 (Xp11.2) gene fusion was examined using the TFE3 break-apart fluorescence in situ hybridization in 5 cases, in which only the malignant case was positive. The next generation sequencing revealed the SFPQ-TFE3 [t(X;1)(p11.2;p34)] fusion. Follow-up of the patients ranged from 12 to 173 months while one patient was lost to the follow-up. The malignant case had tumor metastasis to the brain 4 years after the operation and then received radiotherapy. Other 6 cases had no recurrence and metastasis, and all the 7 patients survived. Conclusions: Most of the PEComas of the lung are benign. When there are malignant morphological features such as necrosis, high-grade nuclei or SFPQ-TFE3 gene fusion, close follow-up seems necessary.

Abstract
OBJECTIVE This study aimed to assess the scanning time (ST) and accuracy of 10 repeated upper and lower dentition scans by four groups of operators with different professional backgrounds. METHODS There were a total of 32 participants, including dentists, nurses, postgraduates, and undergraduates (n=8). They received the same training about intraoral scanning and then performed 10 repeat scans on the plaster maxillary and mandibular dentition models in a manikin head, with the first five scans being the T1 phase and the last five scans being the T2 phase. Each ST was recorded. Trueness and precision were evaluated by root mean square (RMS) value gained from alignments of corresponding virtual models. For statistical analysis, the paired-sample t-tests, one-way ANOVA, and Pearson correlation tests were employed (α=0.05). RESULTS Limiting the comparison in scan phase and scan target the sequence of STs for the four groups was the same (p<0.05), by which undergraduates, postgraduates, nurses, and dentists were in descending order. Undergraduates gained the best precision, followed by postgraduates, dentists, and nurses, in both maxillary and mandibular scanning (p<0.05). Compared with corresponding items of the T1 phase, the trueness of the T2 phase was much higher (p<0.05), while the ST of the T2 phase was much shorter (p<0.05). CONCLUSIONS The operator's professional background affects the precision and scanning time but not the trueness. Most dental personnel have good access to the intraoral scanner. As the number of scans increased, the accuracy and scanning efficiency also improved.

Abstract
SUMMARY As the most prominent feature of the lower face, the chin is crucial to human facial morphology and it plays a large role in contributing to facial attractiveness and harmony. Although an increasing number of genioplasty procedures are being introduced for chin augmentation, chin reduction procedures are rarely performed. Due to the inevitable cervicomental angle (CA) widening and relaxation of the floor-of-mouth muscles caused by chin shortening and the elevation of the lower edge of the mandible, chin reduction remains a challenging procedure. Our novel drawer-genioplasty approach involves a flexible chin-reducing procedure using subapical and mandibular contouring ostectomy. This technique can effectively shorten various long chins for improved facial proportions and maximize the floor-of-mouth muscle protection during surgery, thereby avoiding postoperative submental sagging. Several parameters, including the ratio between the lower (the subnasale to menton distance) and middle facial heights (the glabella to subnasale distance) (R1), the ratio between the anterior midline bone heights of the mandible (the stomion-to-menton distance) and maxilla (the subnasale-to-stomion distance) (R2), and the CA, were used to evaluate the outcome of the procedure. Comparing the preoperative and postoperative parameters revealed that there was a significant decrease in both R1 (1.25±0.15 versus 1.09±0.12) and R2 (1.94±0.24 versus 1.58±0.11). Although CA increased from 107.3±8.2° preoperatively to 112.4±7.0° postoperatively, this value was still within the normal range. In addition to providing effective and significant aesthetic improvements, the drawer-genioplasty is safe and involves no complications.

Abstract
Foreign language learners often encounter various emotional challenges within academic environments, which can hinder their progress in developing literacy skills. Effective language instruction should encompass teaching approaches that acknowledge the emotional requirements of students. To address this need, we propose a multimodal affective methodology designed to evaluate emotions in foreign language education scenarios. This methodology also holds the potential to elucidate the pedagogic contributions of various emotional variables to academic outcomes. Our study focuses on German as a foreign language (GFL) learning and utilizes it as an example to investigate ways to improve writing proficiency. The study explores the effects of integrating multimodal corrective feedback (MCF) into academic writing exercises. We delve into suitable modalities for analyzing emotions in academic writing practices. Furthermore, we investigate how the choice of corrective feedback mode intricately influences the nature of feedback itself and subsequently influences students' emotional responses. Through a comprehensive exploration of the interplay between distinct modes of delivering feedback and their impacts on learners' engagement, this investigation strives to decode the intricate dynamics of emotions that underlie language acquisition. With these insights, the study discusses how teachers can enhance their teaching strategies by combining changes in learners' emotional states and providing emotional support.

Abstract
PURPOSE/OBJECTIVE(S) Approximately half of patients with advanced HER2-positive breast cancer (BC) will develop brain metastases (BM) over time. Local therapy including stereotactic radiotherapy (SRT) and whole brain radiotherapy (WBRT) is the main initial treatment in malignant tumor patients with BM. However, more than 50% patients after radiotherapy in one year suffered intracranial recurrence. Pyrotinib, a small molecule, irreversible, pan-ErbB receptor tyrosine kinase inhibitor (TKI), has a high potency for controlling BM and reducing the occurrence of brain metastases in advanced HER2-positive BC patients. We hypothesized that SRT or WBRT combined with pyrotinib and capecitabine could decrease intracranial progression in HER2 positive BC with newly diagnosed BM. MATERIALS/METHODS In this prospective single-arm phase Ib/II trial (NCT04582968), eligible patients were assigned to either fractionated stereotactic radiotherapy (FSRT) or whole-brain radiation therapy (WBRT), combined with pyrotinib and capecitabine. The primary endpoint was one-year CNS progression-free survival (PFS) rate. Secondary endpoints included intracranial objective response rate (IC-ORR) according to RANO-BM criteria, progression-free survival (PFS), overall survival (OS) and evaluation of safety and neurocognitive function. RESULTS From January 2020 to August 2022, 40 patients were enrolled. Twenty-nine patients were treated with FSRT in 8 Gy per fraction with 3 to 5 fractions and 11 were treated with WBRT in 3 Gy per fraction with 10 fractions, and then received chemotherapy in a time frame starting from 0 to 7 days after radiotherapy. At a median follow-up of 17.3 months, 1-year CNS-PFS rate was 74.9% (95% CI 61.9-90.7%) and median CNS-PFS was 18 months (95% CI, 15.5 to NA months). One-year PFS rate was 66.9% (53.1-84.2%) and median PFS time was 17.6 months (95% CI 12.8-34.1 months). The best intracranial response rate (IC-ORR: complete response and partial response) was 92.5% (37/40). The most common grade 3 or worse toxicity was diarrhea (7.5%) and asymptomatic radiation necrosis was detected in 4 of 67(6.0%) lesions treated with FSRT. No differences of neurocognitive function evaluated by MMSE (Mini-Mental State Exam) were observed between different groups at any time point. CONCLUSION Radiotherapy combined with pyrotinib and capecitabine resulted in a promising efficacy that crossed the pre-specified boundary in patients with HER2-positive advanced breast cancer with brain metastases. This is the first prospective study showing the efficacy and safety of CNS radiotherapy concurrent with pyrotinib and capecitabine in patients with BM from HER2-positive breast cancer. Further investigation in a randomized controlled study is warranted.

Abstract
BACKGROUND Recent studies identified several risk factors of benign prostatic hyperplasia (BPH), including dyslipidemia, type 2 diabetes mellitus, hypertension, and obesity. But they were not so reliable and some studies contradicted with one another. Hence, a reliable method is urgently needed to explore exact factors that facilitated BPH development. METHODS The study was based on Mendelian randomization (MR) design. All participants were from the most recent genome-wide association studies (GWAS) with large sample size. The causal associations between nine phenotypes (total testosterone level, bioavailable testosterone level, sex hormone-binding globulin, high-density lipoprotein cholesterol, low-density lipoprotein cholesterol, triglycerides, type 2 diabetes mellitus, hyper-tension, and body mass index) and BPH outcome were estimated. Two sample MR, bidirectional MR, and multivariate MR (MVMR) were performed. RESULTS Increase in bioavailable testosterone level was able to induce BPH based on nearly all combination methods [beta (95% confidence interval (CI)): 0.20 (0.06-0.34) for inverse variance weighted (IVW)]. The other traits seemed to interact with testosterone level and did not cause BPH generally. Higher triglycerides level was likely to raise bioavailable testosterone level [beta (95% CI): 0.04 (0.01-0.06) for IVW]. In MVMR model, bioavailable testosterone level was still associated with BPH occurrence [beta (95% CI) 0.27 (0.03-0.50) for IVW]. CONCLUSIONS We for the first time validated the central role of bioavailable testosterone level in the pathogenesis of BPH. The complex associations between other traits and BPH should be further investigated.

Abstract
BACKGROUND This article aims to analyze the relationship between user characteristics on social networks and influenza. METHODS Three specific research questions are investigated: (1) we classify Weibo updates to recognize influenza-related information based on machine learning algorithms and propose a quantitative model for influenza susceptibility in social networks; (2) we adopt in-degree indicator from complex networks theory as social media status to verify its coefficient correlation with influenza susceptibility; (3) we also apply the LDA topic model to explore users' physical condition from Weibo to further calculate its coefficient correlation with influenza susceptibility. From the perspective of social networking status, we analyze and extract influenza-related information from social media, with many advantages including efficiency, low cost, and real time. RESULTS We find a moderate negative correlation between the susceptibility of users to influenza and social network status, while there is a significant positive correlation between physical condition and susceptibility to influenza. CONCLUSIONS Our findings reveal the laws behind the phenomenon of online disease transmission, and providing important evidence for analyzing, predicting, and preventing disease transmission. Also, this study provides theoretical and methodological underpinnings for further exploration and measurement of more factors associated with infection control and public health from social networks.

Abstract
Objective: To investigate the clinicopathological characteristics of esophageal carcinoma with gland duct differentiation. Methods: The clinical, morphologic and immunohistochemical (IHC) features of eight cases of esophageal carcinoma with gland duct differentiation diagnosed from 2012 to 2022 at the First Affiliated Hospital of Soochow University were summarized. Results: There were four males and four females, with a mean age of 68.5 (range 59-82) years. Two tumors were located in middle esophagus, five in the lower esophagus, and one in the cardia. The mean diameter was 2.4 cm (range 0.6-4.5 cm). The tumor had a bilayer epithelial structure, including the inner luminal epithelium and the outer basal epithelium. Immunohistochemistry showed that CK7 (8/8) and CK18 (8/8) were positive in the inner epithelium. p40 (8/8), p63 (8/8) and CK5/6 (8/8) were positive in the outer epithelium. SMA, calponin and CD117 were all negative. p53 mutants were found in all eight cases (strong and diffuse positivity in 6/8; complete loss of expression in 2/8). No columnar metaplasia, intestinal metaplasia and ectopic gastric mucosa were observed in the surface squamous epithelium in the cases. The mean follow-up time was 21.5 months (range 5-51 months). Seven patients survived and one patient died 31 months after surgery due to recurrence and liver metastasis. Conclusion: Esophageal carcinoma with esophageal gland duct differentiation is a rare tumor with unique histologic and IHC characteristics.

Abstract
Objective: To understand the incidence of delayed vaccination with the national immunization program vaccines among children aged 0-6 years in Xuhui District, Shanghai, and to evaluate the safety of delayed vaccination. Methods: A stratified random sampling was used to obtain six vaccination clinics in Xuhui District, Shanghai. The vaccination records of children 0-6 years from these six vaccination clinics were collected from the Shanghai Immunization Program Information Management System. Adverse events following immunization (AEFI) data were collected from the China Information System for Disease Control and Prevention. Descriptive epidemiology was used to analyze the data. Children were divided into the timely vaccination group and delayed vaccination group according whether they were delayed in vaccination (received one month or more after the recommended age among children aged ≤1 year; received three months or more after the recommended age among children aged >1 year). The safety of four vaccination methods-individual vaccination, simultaneous vaccination, routine vaccination and combined vaccination-were further compared. Differences between groups were compared using chi-square test. Results: From 2019 to 2021, six vaccination clinics in Xuhui District administered 124 031 doses of the national immunization program vaccines among children aged 0-6 years, and delayed vaccinations accounted for 25.99% (32 234/124 031) of these doses. In 2020, the delayed vaccination rate during the first-level COVID-19 public health emergency response period in Shanghai was significantly higher than that in the same period in 2019 (34.70% vs. 24.19%, χ2=136.23, P<0.05). The delayed vaccination rate during the COVID-19 vaccination campaign in 2021 was significantly higher than that in the same period in 2019 (25.27% vs. 22.55%, χ2=82.80, P<0.05). From 2019 to 2021, a total of 475 cases of AEFI were reported in six vaccination clinics, with a reported incidence of 382.97 per 100 000 doses, including 421 cases of common adverse reaction (88.63%, 339.43 per 100 000 doses), 51 cases of rare adverse reaction (10.74%, 41.12 per 100 000 doses) and 3 cases of coincidences (0.63%, 2.42 per 100 000 doses). The reported incidence of AEFI among delayed vaccinations was significantly lower than that among timely vaccinations (291.62 per 100 000 doses vs. 415.05 per 100 000 doses). The incidence of AEFI for the four delayed vaccination methods (individual vaccination, simultaneous vaccination, routine vaccination and combined vaccination) was lower than that for timely vaccination. There were significant differences between the groups except for the routine vaccination group (χ2=9.82, P<0.05; χ2=5.46, P<0.05; χ2=2.97, P>0.05; χ2=11.89, P<0.05). Conclusions: In Xuhui District of Shanghai, 25.99% of doses of the national immunization program vaccines administered to children 0-6 years were delayed. Delayed vaccination does not increase the risk of AEFI compared with timely vaccination.

Abstract
BACKGROUND Anterolateral thigh (ALT) adipofascial free flap transfer is a frequently used method to reconstruct the facial symmetry and restore facial soft-tissue contour in PRS patients. While its long-term prognosis and patient outcomes assessment are still lack of understanding. METHOD The authors report their treatment experience in 42 patients between 2001 and 2017 using microsurgical free anterolateral thigh adipofascial flap transfer. The long-term follow-up results and final reconstructive outcomes were evaluated. RESULTS A total of 42 patients were included. The follow-up ranged from 5 to 21 years. All patients were satisfied with the surgery. Photographic evaluation revealed significant enhancement of postoperative appearance. Numbness or hypesthesia of the local area was the most common symptom in the long-term follow up. CONCLUSION This study has evaluated the long-term treatment results of Parry-Romberg disease with microsurgery using ALT free flap in our department. Over 20 years' experience and the significant enhancement of the overall appearance indicate a long-lasting, excellent outcome.

Abstract
Objective: To analyze the direct economic burden caused by measles cases in Shanghai from 2017 to 2019 and its influencing factors. Methods: A total of 161 laboratory-confirmed measles cases reported from January 1, 2017, to December 31, 2019, in Shanghai were included in the study through the "Measles Surveillance Information Reporting and Management System" of the "China Disease Surveillance Information Reporting and Management System". Through telephone follow-up and consulting hospital data, the basic information of population, medical treatment situation, medical treatment costs and other information were collected, and the direct economic burden of cases was calculated, including registration fees, examination fees, hospitalization fees, medical fees and other disease treatment expenses, as well as transportation and other expenses of cases. The multiple linear regression model was used to analyze the main influencing factors of the direct economic burden. Results: The age of 161 measles cases M (Q1, Q3) was 28.21 (13.33, 37.00) years. Male cases (56.52%) were more than female cases (43.48%). The largest number of cases was≥18 years old (70.81%). The total direct economic burden of 161 measles cases was 540 851.14 yuan, and the per capita direct economic burden was 3 359.32 yuan. The direct economic burden M (Q1, Q3) was 873.00 (245.01, 4 014.79) yuan per person. The results of multiple linear regression model analysis showed that compared with other and unknown occupations, central areas and non-hospitalized cases, the direct economic burden of measles cases was higher in scattered children, childcare children, students, and cadre staff in the occupational distribution, suburban areas and hospitalized, with the coefficient of β (95%CI) values of 0.388 (0.150-0.627), 0.297 (0.025-0.569), 0.327 (0.148-0.506) and 1.031 (0.853-1.209), respectively (all P values<0.05). Conclusion: The direct economic burden of some measles cases in Shanghai is relatively high. Occupation, area of residence and hospitalization are the main factors influencing the direct economic burden of measles cases.

Abstract
OBJECTIVE This study was performed to evaluate the efficacy of immediate cytoreductive nephrectomy (CRN) followed by programmed cell death factor-1 (PD-1) inhibitors vs. deferred CRN after the administration of 4 cycles of neoadjuvant therapy using nivolumab preceding the debulking and postoperative chemotherapy in metastatic renal cell carcinoma (mRCC). PATIENTS AND METHODS We recruited 84 patients with primary mRCC admitted to our Oncology Department from 2018 to 2020 and randomized them 1:1 to receive either CRN followed by nivolumab (control group) or 4 cycles of neoadjuvant therapy using nivolumab before CRN and postoperative chemotherapy (study group), with 42 patients in each group. The primary clinical endpoints were the clinical efficacy and safety of the PD-1 antibody. Clinical outcomes were assessed 3 months after treatment. RESULTS Patients were followed-up for 10-52 months, with a median follow-up period of 40.50 months. The control group reported 2 cases of complete remission and 10 cases of partial remission, with an objective response rate (ORR) of 28.57% (12/42). The study group reported 4 cases of complete remission and 14 cases of partial remission with an ORR of 42.86% (18/42). No significant differences in the ORR were identified between the two groups (p > 0.05). Progression-free survival of the patients was significantly extended from 30 months (19-51) to 43 months (38-76) after administrating the PD-1 inhibitors before the debulking (HR = 0.501, 95% CI: 0.266 to 0.942). There were no significant differences in the median survival of patients between the two groups [44 months (38-79) vs. 44 months (32-81)] (HR = 0.814, 95% CI: 0.412 to 1.612). The two protocols had a similar safety profile. CONCLUSIONS Nivolumab administration preceding delayed CRN provides significant progression-free survival benefits for patients with mRCC, but its impact on overall survival requires further investigations.

Abstract
We disclose herein an efficient photochemical formal [3+2+1] annulation strategy for the transformation of diazocarbonyl compounds into various fluorinated nitrogen-containing heterocycles. This transformation is characterized by reacting fluoroalkyl radicals with α-diazoketones, which are used as infrequent denitrogenated synthons under visible light. Moreover, a wide range of N-heterocycles containing precious CF3 and perfluoroalkylated groups are constructed in moderate to good yields. Notably, this photochemical strategy may provide a fruitful path for the synthesis of complex organofluorides via diazo/fluorine/radical chemistry.

Abstract
In the Multi beam source (MBS) of our Multi Beam Scanning Electron Microscope (MBSEM), an aperture lens array (ALA) splits the emission cone of the Schottky field emitter into multiple beamlets. When the apertures in the ALA are close to each other, the ALA can introduce aberrations to these beamlets through the electrostatic interaction of neighbouring apertures with each aperture's lens field. When the apertures are arranged in a square grid pattern, the aberration causes fourfold astigmatism. The effect on the beam spot is analyzed through a combination of 3D simulations and experimental validation. To counterbalance the fourfold astigmatism, a correction scheme is proposed in which a slightly non-round profile is applied to the aperture lenses.

Abstract
Objective This research aim was to evaluates the role of the pre-ablation neutrophil-to-lymphocyte ratio (NLR) and lymphocyte-to-monocyte ratio (LMR) as predictors of distant metastases in patients with differentiated thyroid cancer (DTC). Methods A retrospective analysis was given to 140 patients with DTC who received 131I remnant ablation after surgery. The patients were divided into two groups based on the existence of distant metastasis. Results The two groups showed no significant difference in age, gender, WBCs, neutrophils, monocytes, eosinophils, basophils and whether the tumor was multifocal. In the univariate analysis, significant differences were found in tumor size (p=0.021), lymphocyte (p=0.012), NLR (p=0.027), and LMR (p=0.007). According to the ROC curves, NLR had an AUC of 0.612 ± 0.097 with a cut-off value of 1.845, sensitivity of 60.0%, and specificity of 66.2% (p=0.027). LMR had an AUC of 0.638 ± 0.095 with a cut-off value of 4.630, sensitivity of 84.6%, and specificity of 35.4% (p=0.007). In the multivariate analysis, larger tumor size (OR=5.246, 95% CI 1.269-10.907, p=0.009) and higher NLR (OR=2.087, 95% CI 0.977-4.459, p=0.034) were statistically significant for distant metastases. Conclusion This research reveals that pre-ablation NLR and tumor size are significantly statistically correlated with distant metastases in patients with DTC.

Abstract
Orthokeratology (Ortho-K) is one of the effective methods to control the development of myopia in children and adolescents. The mechanical pressure of eyelids on the Ortho-K lens and the hydraulic effect of tears under the Ortho-K lens can alter the curvature or shape of the cornea, which can correct refractive error and control myopia development progress. The tear film is a thin layer of liquids evenly distributing in the conjunctival sac. Wearing an Ortho-K lens can decrease the tear film stability, which will influence the Ortho-K. In this article, the relevant domestic and overseas research results are summarized and analyzed, aiming to sort out and discuss the effection of tear film stability on the fitting, shaping, safety, and visual quality of the Ortho-K, as well as to provide suggestions for clinicians and researchers.

Abstract
Combined crown and post-and-core treatment often requires multiple intermittent appointments and takes a long time. This article describes a novel method for simultaneously fabricating a custom glass fiber post-and-core and the corresponding crown. The critical step, defined as a post-and-core virtual try-in, is to construct a virtual crown abutment that mimics the profile of a real one gained after post-cementation and tooth preparation. The fully digital workflow optimizes the treatment and saves time by accomplishing restorations on the first visit.

Abstract
PURPOSE Low-intensity pulsed ultrasound (LIPUS) has been used to stimulate the healing of the fresh fracture, delayed union, and non-union in both animal and clinical studies. Besides, biphasic calcium phosphate ceramic (BCP) is a promising biomaterial for bone repair as it shows favorable biocompatibility, osteoinduction, and osteoconduction. However, scarcity is known about the combined effect of LIPUS and BCP on bone formation. METHODS The combined effect of LIPUS and BCP was studied in a beagle model. Twelve dogs were used. BCP granules without any additions were implanted into bilateral erector spinae muscles. One side is the BCP group, while the counterlateral side is LIPUS + BCP group. Histological and histomorphometric analyses, and quantitative real-time polymerase chain reaction were evaluated. RESULTS Compared with BCP alone, the LIPUS + BCP showed no advantages in early bone formation. Furthermore, the Notch signaling pathway-related mRNA has no significant difference between the two groups. CONCLUSIONS The preliminary results showed that the BCP, which has intrinsic osteoinduction nature, was an effective and promising material. However, LIPUS has no enhanced effect in BCP induced ectopic bone formation. Furthermore, LIPUS has no effect on the Notch signaling pathway. Whether costly LIPUS could be used in combination with BCP should be a rethink.

Abstract
PURPOSE Non-alcoholic fatty liver disease (NAFLD) is a common chronic liver disease. This study examined sex-specific associations between NAFLD and metabolic factors and investigated the trajectory of risk factors. METHODS We retrospectively investigated 16,140 individuals from Beijing Health Management Cohort. Univariate and multivariate time-dependent Cox regression analyses were performed to identify independent risk factors for new-onset NAFLD. The trajectory of risk factors was investigated using the latent growth curve model and growth mixture model. RESULTS Over a median follow-up of 3.15 years, 2,450 (15.18%) participants developed NAFLD. The risk factors for NAFLD in men were increased body mass index (BMI); waist circumference (WC); triglyceride (TG), low-density lipoprotein cholesterol (LDL-C), haemoglobin (Hb), and serum uric acid (SUA) levels; and platelet (PLT) count and decreased serum creatinine-to-body weight (sCr/bw) and high-density lipoprotein cholesterol (HDL-C) levels. In women, the risk factors were increased BMI, WC, and fasting plasma glucose (FPG), TG, LDL-C, SUA, white blood cell (WBC), and PLT and decreased sCr/bw and HDL-C levels. In addition, BMI, LDL-C, sCr/bw and PLT changing trajectories were associated with NAFLD in men; BMI, WC, TG, LDL-C, SUA and sCr/bw trends was associated with NAFLD risk in women. CONCLUSIONS Development of NAFLD is associated with BMI, LDL-C, sCr/bw and PLT changing trajectories in men; BMI, WC, TG, LDL-C, SUA and sCr/bw trends are associated an increased risk of NAFLD in women. Deterioration of metabolic risk factors status can be a predictor of NAFLD many years before its occurrence.

Abstract
BACKGROUND The EmboTrap Recanalization Device is a novel stent retriever for thrombectomy in the setting of acute ischemic stroke due to large-vessel occlusion. PURPOSE Our aim was to summarize the safety and efficacy of the EmboTrap Recanalization Device in acute ischemic stroke-large-vessel occlusion through a systematic review and meta-analysis. DATA SOURCES Medline, EMBASE, the Cochrane Library, Web of Science, and Google Scholar were searched up to April 2022. STUDY SELECTION Nine observational studies using the EmboTrap Recanalization Device were selected. DATA ANALYSIS We adapted effect size with 95% CIs for dichotomous data. P value <.05 was statistically significant. DATA SYNTHESIS The estimated rate of successful recanalization (modified TICI 2b-3) was 90% (95% CI, 86%-95%; I 2 = 82.4%); 90-day favorable outcome (mRS 0-2), 53% (95% CI, 42%-63%; I 2 = 88.6%); modified first-pass effect, 43% (95% CI, 35%-51%; I 2 = 63.7%); and first-pass effect, 36% (95% CI, 29%-46%; I 2 = 10.7%). The rate of any intracerebral hemorrhage was 19% (95% CI, 16%-22%; I 2 = 0.0%); symptomatic intracerebral hemorrhage, 5% (95% CI, 1%-8%; I 2 = 84.6%); and 90-day mortality, 14% (95% CI, 9%-19%; I 2 = 79.3%). Subgroup analysis showed higher rates of complete recanalization for EmboTrap II than for the EmboTrap System. LIMITATIONS The included studies are single-arm without direct comparison with other stent retrievers. Some of the studies recruited had a small sample size and were limited by the retrospective study design. In addition, the uncertain heterogeneity among studies was high. CONCLUSIONS The EmboTrap Recanalization Device is safe and efficient in treating acute ischemic stroke due to large-vessel occlusion.

Abstract
Objective: To evaluate the efficacy of the Hodgkin lymphoma (HL)-2013 regimen in the treatment of children with HL, and to investigate the prognostic factors of childhood HL. Methods: Clinical data of 145 children (aged ≤18 years) with newly diagnosed HL, treated with HL-2013 regimen in 8 tertiary referral centers for childhood cancer from August 2011 to April 2021 were analyzed retrospectively. All the diagnosis were confirmed by histopathological morphology and immunohistochemical examination. The clinical characteristics and treatment outcomes were summarized, and the patients were divided into different groups according to clinical characteristics. Kaplan-Meier method was used for survival analysis, and the comparison of survival rates between groups was performed with Log-rank test. Results: Of the 145 cases, there were 115 males and 30 females, the age at diagnosis was 7.9 (5.8, 10.6) years. Cervical lymph node enlargement (114 cases, 78.6%) was the common symptom of the disease, and 57 patients (39.3%) were accompanied by large masses. The most common pathological classification was mixed cell type (93 cases, 64.1%). According to the Ann Arbor staging system, there were 9 cases of stage Ⅰ, 62 cases of stage Ⅱ, 45 cases of stage Ⅲ, 29 cases of stage Ⅳ. According to the risk stratification: there were 14 cases of low-risk group, 76 cases of medium-risk group and 55 cases of high-risk group. Of all patients, 68 cases (46.9%) achieved an early complete remission (CR) after 2 courses of chemotherapy, and the CR rate was 93.8% (136/145) after first-line treatment. Disease recurrence or progression occurred in 22 cases (15.2%). Of all patients, 125 cases survived, 6 cases died and 14 cases were lost to follow-up. Among the survived cases, 123 cases were continuously at CR state,and the follow-up time was 55 (40, 76) months. The 5-year overall survival (OS) and event free survival (EFS) rates were (95.3±1.9)% and (84.2±3.0)% for the entire group, respectively. 5-year OS and EFS rates for patients with stage Ⅲ-Ⅳ were both lower than those for patients with stage Ⅰ-Ⅱ (χ2=6.28 and 7.58, both P<0.05), the 5-year OS and EFS rates for patients in high-risk group were both lower than those for patients in low-risk and medium-risk group (χ2=10.93, 7.79, both P<0.05). The 5-year OS rates for the patient with early CR and without early CR were 100.0% and (90.9±3.6)% (χ2=5.77, P=0.016). EFS rates for the patient with early CR (68 cases) and without early CR (77 cases) were (93.8±3.0)% and (75.8±5.0)% (χ2=8.78, P=0.003). Conclusions: HL-2013 regimen is significantly effective in the treatment of pediatric HL. However, the patients in high-risk group and those without early CR are prone to disease recurrence or progression. Stage Ⅲ-Ⅳ and without early CR were associated with worse prognosis.

Abstract
BACKGROUND Our study aimed to investigate the prevalence and demographic characteristics of immune checkpoint inhibitor-associated primary adrenal insufficiency (ICI-PAI) and to explore the risk factors of its clinical outcome using data from the US FDA Adverse Event Reporting System (FAERS). METHODS This was a retrospective study. All cases of new-onset or newly diagnosed primary adrenal insufficiency associated with FDA-approved ICIs from 1 January 2007 to 31 December 2020 were identified and collected using FAERS. Data on age, sex category, body weight of the participating individuals, the reporting year and the prognosis of cases, and other accompanying endocrinopathies related to ICIs, were analysed. RESULTS The incidence of ICI-PAI was 1.03% (1180/114121). Of the 1180 cases of PAI, 46 were "confirmed PAI", and 1134 were "suspected PAI". Combination therapy with anti-CTLA-4 and anti-PD-1 was related to a higher risk of PAI compared with the anti-PD-1-only group (χ2 = 92.88, p < 0.001). Male and elderly individuals showed a higher risk of ICI-PAI (male vs. female, 1.17% vs. 0.94%, χ2 = 12.55, p < 0.001; age < 65 vs. ≥ 65, 1.20 vs. 1.41%, χ2 = 6.89, p = 0.009). The co-occurrence rate of endocrinopathies other than PAI was 24.3%, which showed a higher trend in patients on nivolumab-ipilimumab treatment than in those on PD-1 inhibitors (χ2 = 3.227, p = 0.072). Body weight was negatively associated with the risk of death in the study population [p = 0.033 for the regression model; B = - 0.017, OR 0.984, 95% CI (0.969-0.998), p = 0.029]. CONCLUSION ICI-associated PAI is a rare but important irAE. Male and elderly patients have a higher risk of ICI-PAI. Awareness among clinicians is critical when patients with a lower body weight develop PAI, which indicates a higher risk of a poor clinical outcome.

Abstract
In recent years, biochar, a porous carbon-based material, has gained attention for its application prospects in contaminated soil remediation and soil improvement. Biochar-derived organic matter has a key role in influencing the migration and transformation of soil elements and pollutants. However, existing research concerning the molecular characteristics of biochar-derived organic matter is limited. Here, we used four polar solvents - dichloromethane (CH2Cl2), acetone (CH3COCH3), methanol (CH3OH), and distilled water (H2O) - to extract organic matter from soybean straw biochar and wheat straw biochar by accelerated solvent extraction (ASE). We characterized the extracts using Fourier-transform ion cyclotron resonance mass spectrometry (FT-ICR-MS). We found considerable differences in organic matter according to the extraction solvents; such differences were related to the polarity of the solvent, as well as intermolecular forces between the solvent and organic matter. CH3OH extracted the most biochar-extractable organic matter components because CH3OH can weaken or destroy oxygen bridge bonds in biochar and form hydrogen bonds with small-molecule organic compounds. CH3OH and H2O have strong extraction capacity for compounds containing heteroatoms. CH2Cl2-extractable organic matter is relatively labile and bioavailable, while CH3OH- and H2O-extractable organic matters are relatively stable. In addition, the binding capacity of biochar-derived organic matter for minerals and pollutants differed among fractions, in part because of differences in molecular weight, atomic O/C and H/C ratios, heteroatom distribution, and biomolecular compounds present in biochar-derived organic matter. The findings in this study help to select appropriate extractants to analyze biochar-derived organic matter for various research purposes, and provides a theoretical basis for biochar-based remediation of contaminated soil.

Abstract
Objective: To study the clinical significance of autoantibodies against different ubiquitin carboxyl hydrolase L1 (UCH-L1) epitopes in Sjogren syndrome (SS). Methods: The serum levels of different UCH-L1 epitope autoantibodies in 98 SS patients [SS group, 17 males and 81 females, aged (49.1±12.3) years] in the Fifth Affiliated Hospital of Zhengzhou University and Peking University People's Hospital from January 2017 to January 2020 and 37 healthy controls [control group, 6 males and 31 females, aged (46.3±5.8) years] were determined by enzyme-linked immunosorbent assay (ELISA). Three potential epitopes of UCH-L1 protein were analyzed and synthesized and anti-UCH-L1203-214 and anti-UCH-L158-69 antibodies were studied between the two groups. The levels of the two anti-UCH-L1 antibodies in the two groups were compared. The correlation between the levels of UCH-L1 antibodies and clinical data of SS patients were analyzed by Pearson correlation analysis. Results: The serum levels of anti-UCH-L1203-214 and anti-UCH-L158-69 antibody in SS patients were significantly higher than those in healthy controls (HCs) (anti-UCH-L1203-214: 108.2±54.3 vs 78.9±25.8, P<0.001, anti-UCH-L158-69: 86.8±33.3 vs 60.4±21.5, P<0.001). The positive rates of anti-UCH-L1203-214 and anti-UCH-L158-69 antibodies in serums of SS patients were 27.6 % (27/98) and 25.5% (25/98), and those in HCs were 2.7%(1/37) and 5.4 %(2/37), respectively. In SS patients with positive serum anti-UCH-L158-69 antibody, the levels of IgG, γ globulin and rheumatoid factor (RF) and anti-SS-related antigen B (anti-SSB) antibody positive rate were all significantly higher than those in patients with negative antibody (all P<0.05). In SS patients with negative antinuclear antibody (ANA), anti-RNA binding protein (anti-RNP) antibody, anti-SS-related antigen A (anti-SSA) antibody and anti-SSB antibody, the positive rates of anti-UCH-L1203-214 antibody was 32.1%(9/28), 27.2%(25/92), 36.4%(12/33), 28.6%(18/63), respectively; and the positive rates of anti-UCH-L158-69 antibody was 21.4%(6/28), 30.4%(28/92), 30.3%(10/33), 20.6%(13/63), respectively. The level of serum anti-UCH-L1203-214 antibody in SS patients was positively correlated with the IgA level (r=0.21, P=0.024). The level of anti-UCH-L158-69 antibody in SS patients was positively correlated with the levels of γ-globulin, IgG and RF (r=0.35, 0.33, 0.32, all P<0.01). Conclusion: Autoantibodies against UCH-L1 epitopes are correlated with some clinical parameters of SS patients, which is of promising significance in the screening and diagnosis of SS.

Abstract
Abstract
Background
Radiotherapy and surgery are the standard treatments for lung cancer brain metastases (BMs). However, limitted studies focused on the treatments for patients with lung cancer BMs with poor prognosis factors. The purpose of this study was to investigate the effects of radiotherapy and surgery in patients with lung cancer BMs with poor prognosis factors, providing reference for clinical strategies.
Material and Methods
We analyzed retrospectively 714 patients with lung cancer BMs. A 1:1 propensity score matching (PSM) was performed to balance potential confounders. Analyses of overall survival (OS) and risk factors for OS were assessed by log-rank test and Cox proportional hazard model.
Results
Age ≥65 years, Karnofsky Performance Scale (KPS) score ≤70, anaplastic large-cell lymphoma kinase (ALK)/epidermal growth factor receptor (EGFR) wild type, extracranial metastases, non-surgery and non-radiotherapy led to poor prognosis. Patients were stratified according to these factors. Radiotherapy and surgery showed no survival benefit in patients with aged ≥65 years or pretreatment KPS score ≤70 before and after PSM. Before PSM, whole brain radiotherapy (WBRT) improved the OS and predicted good prognosis in patients with ALK/EGFR wild type or extracranial metastases. WBRT also predicted good prognosis in patients with non-surgery. Stereotactic radiosurgery (SRS) improved the OS and predicted good prognosis in patients with ALK/EGFR wild type or non-surgery. WBRT plus SRS improved the OS and predicted good prognosis in patients with extracranial metastases or non-surgery. WBRT plus SRS also predicted good prognosis in patients with ALK/EGFR wild type. Surgery improved the OS and predicted good prognosis in patients with non-radiotherapy. After PSM, SRS improved the OS and predicted good prognosis in patients with non-surgery. WBRT plus SRS improved the OS and predicted good prognosis in patients with non-surgery or extracranial metastases. WBRT plus SRS also predicted good prognosis in patients with ALK/EGFR wild type. Surgery improved the OS of patients with non-radiotherapy. We defined that the treatment would provide significant survival benefit if it both prolonged the OS and predicted good prognosis. Meanwhile, the results after PSM were more convincing than the results before PSM.
Conclusion
Radiotherapy has significant survival benefit in patients with lung cancer BMs with poor prognosis factors, including patients with ALK/EGFR wild type or extracranial metastases or non-surgery. Surgery only has significant survival benefit in patients with non-radiotherapy.

Abstract
AIM To improve the accuracy of diagnosis of Rosai-Dorfman disease (RDD) by summarising the computed tomography (CT) and magnetic resonance imaging (MRI) characteristics. MATERIALS AND METHODS The clinical manifestations, imaging findings, and pathological characteristics of 14 patients with histopathologically confirmed RDD were analysed retrospectively and a literature review was undertaken. RESULTS Of the 14 patients, nine had multiple lesions and five had single lesions. Eight patients had extranodal lesions, while six had mixed-type lesions. In patients with head and neck lesions, plain CT/MRI revealed irregularly shaped, well-defined, homogeneous, and mainly progressive lesions, with marked homogeneous enhancement on multiphasic contrast-enhanced imaging. One patient had dural lesions, one of which iso-intense to grey matter, with patchy hypo-intensity on T2-weighted imaging, meningeal tail signs, and characteristic crabfoot-like enhancement. Three patients with skeletal system involvement exhibited osteolytic bone destruction without sclerosis at the edges, associated soft-tissue masses, or periosteal reactions. Two patients had well-defined subcutaneous lesions, inhomogeneous density, and progressive parenchymal enhancement on contrast-enhanced CT. One patient had multiple intestinal lesions with inhomogeneous nodular thickening of the blind ascending colon and ileum, with marked and progressive enhancement. CONCLUSION RDD involvement is mainly multifocal, primarily in the head and neck regions. Plain CT/MRI revealed well-defined, irregularly shaped lesions with homogeneous density/signal, with marked and progressive enhancement on multiphasic contrast-enhanced imaging; however, histopathology is still required to confirm the diagnosis of RDD.

Abstract
Objective: To investigate the efficacy and safety of the combination therapy with chemotherapy, programmed death-1 (PD-1) inhibitor and anlotinib in the treatment of advanced dedifferentiated liposarcoma (DDLPS). Methods: The clinical data of patients with dedifferentiated liposarcoma who received chemotherapy combined with PD-1 inhibitor and anlotinib in the Department of Medical Oncology, Zhongshan Hospital Affiliated to Fudan University from January 1, 2020 to November 30, 2021 were retrospectively analyzed. A total of 24 patients were included in this study, including 12 males and 12 females, with a median age of onset of 56 years (range, 31-69 years). Efficacy and safety in those patients were assessed. Results: All patients had unresectable or metastatic dedifferentiated liposarcoma with G2 (moderate differentiation) or G3 (differential differentiation) in a concise three-grade grading scheme of tumor pathology. Twelve patients received the regimen as the first-line treatment, while the other 7 taken the regimen as second-line treatment and 5 as third-line or above. The median follow-up time for overall survival (OS) was 7.7 months. The overall response rate (ORR) was 20.8% (5/24) and disease control rate (DCR) was 83.3% (20/24) with 5 partial response (PR), 15 stable disease (SD) and 4 progressive disease (PD). Overall, the median progression-free survival (PFS) was 4.9 months (95%CI: 3.4-16.2 months). The ORR of anthracycline-based, eribulin-based or gemcitabine-based regimens was 1/12, 2/6 and 2/6, respectively; and the median PFS was 7.7, 7.3 and 4.4 months, respectively. Waterfall plots showed notable tumor shrinkage of any degree in eribulin and gemcitabine-based regimens(3/6 and 2/6, respectively), while there were more patients presented with SD in anthracycline-based group(9/12). Common adverse reactions included myelosuppression, fatigue, anorexia, rash, pruritus, palpitate, hypothyroidism and hypertension. Conclusions: The combination regimen with chemotherapy, PD-1 inhibitor and anlotinib in the treatment of advanced DDLPS is effective and well tolerable. There are more responders in eribulin or gemcitabine-based regimens.

Abstract
BACKGROUND In east Asia, lower face contouring surgeries including reduction mandibuloplasty and genioplasty are the most popular aesthetic craniofacial surgeries. Conventional selection of surgical strategies mainly relied on the visual judgment of the mandibular angle, without overall assessment of the mandibular sub-units. Furthermore, only a few studies offered quantitative assessment of the mandibular shape. METHODS From 2010 to 2021, 1241 patients diagnosed with square faces and received customized lower face contouring surgeries by the senior author were reviewed and analyzed to propose an "ABC" classification system for facilitating surgical planning. RESULTS Among them, 998 (80.42%) received bilateral mandible reshaping, 155 (12.49%) underwent bilateral mandible reshaping combined with genioplasty, and 88 (7.09%) received asymmetric mandible reshaping. A modified classification system composed of three critical parameters (height, morphology/thickness, divergence) in three aesthetic zones (mandibular angle, mandibular body, chin) was proposed based on quantitative summarization of the CT database and the senior author's 12-year experience. The way to facilitate surgical planning with this classification was demonstrated. CONCLUSIONS This modified classification system ushered a decision-making process that prioritized several critical measurements and proposed an operative planning form. Meanwhile, it can also be cooperated into the three-dimensional virtual surgical plan. LEVEL OF EVIDENCE IV This journal requires that authors assign a level of evidence to each article.

Abstract
Objective: To study the safety and efficacy of transjugular intrahepatic portosystemic shunt (TIPS) combined with iodine-125 (125Ⅰ) seed strands implantation in patients with hepatocellular carcinoma combined with portal vein tumor thrombosis. Methods: 25 cases with diffuse intrahepatic tumor combined with tumor thrombus type Ⅲ/Ⅳ requiring TIPS were simultaneously implanted with 125Ⅰseed strand. Tumor thrombus was controlled with 125I seed implantation brachytherapy to keep the TIPS pathway unobstructed, reduce the portal vein pressure, and observe the changes in the cause of death of the patients. During the same period, 30 cases without TIPS and seed strand implantation were used as controls. Data between groups were compared using t-test, Chi-Squared test or Fisher's exact test. Results: TIPS combined with 125Ⅰ seed strand implantation was safe in patients with diffuse hepatocellular carcinoma combined with type III/IV portal vein tumor thrombus, and 92.0% (23/25) of the patients maintained unobstructed TIPS pathway. Compared with the control group, patients in the treatment group died of fewer lead-related complications, and most died from chronic liver failure (84.0% vs. 56.7%, χ2 = 4.771, P=0.029). The incidence of upper gastrointestinal bleeding was significantly decreased (12.0% vs. 46.7%, χ2 =7.674, P=0.006) and ascites severity was significantly improved (mild 40.0% vs. 16.7%, moderate 52.0% vs. 20.0%, severe 8.0% vs. 46.7%, χ2 =13.246 , P=0.001). Conclusions: TIPS combined with 125Ⅰ seed strand implantation is safe and feasible in patients with diffuse intrahepatic tumor combined with tumor thrombus type Ⅲ/Ⅳ. Moreover, it can effectively keep the shunt patency and reduce portal vein pressure, thereby reducing the incidence of upper gastrointestinal bleeding and improving the degree of ascites. TIPS combined with 125Ⅰ seed strand implantation may be used as a standard treatment modality for patients requiring TIPS therapy combined with tumor thrombus type Ⅲ/Ⅳ.

Abstract
Abstract
Introduction
Epidemiological studies suggested that exposure to transportation noise and long-term community noise was associated with a higher incidence of dementia, especially Alzheimer’s disease (ad). However, since subjects with low education and low income were also more likely to live or work in noisy environments, the association observed between noise exposure and ad may be distorted by education level, income level, and hearing impairment. Thus, whether noise exposure was causally associated with ad risk remained to be further clarified.
Method
A bidirectional Mendelian randomization (BMR) analysis was performed leveraging genome-wide association studies (GWAS) summary statistics of noise exposure (N = 456,380, UK Biobank) and ad (N = 54,162, IGAP) from the OpenGWAS database. Those single nucleotide polymorphisms (SNPs) with a P value less than 1E-05 were selected as instrumental variables (IVs). The TwoSampleMR package (version 0.5.6) was used to do BMR analysis using the inverse variance weighted (IVW) method with default parameters.
Results
The IVW results howed that exposure to noise at different times of day was causally associated with increased risk of ad (daytime: odds ratio [OR] = 2.2113, P = 0.0326; evening: OR = 2.2127, P = 0.0324; nighttime: OR = 2.2110, P = 0.0326; 16-hour: OR = 2.2114, P = 0.0325; 24-hour: OR = 2.2128, P = 0.0324). No obvious pleiotropic effects and heterogeneity were found in the BMR analysis, suggesting good reliability of the causal effect of noise exposure on ad. Moreover, the BMR results remained significant despite removing IVs associated with an education degree, average income, and hearing impairment. There was no reverse causal effect of ad on noise exposure in BMR analysis, which has been deposited in FigShare (https://figshare.com/s/09e30a1a0ccff450246b).
Conclusion
The results BMR analysis demonstrate that noise exposure is causally associated with an elevated risk of ad, independently of education degree, average income, and hearing impairment. Further studies are needed to confirm the underlying mechanism of this effect.

Abstract
Abstract
Background
Frailty is common in people with COPD. This systematic review assesses prevalence and trajectory of frailty and associations with adverse health outcomes in people with COPD.
Method
Three databases searched (Medline, Embase and Web of Science) from 2001 to September 2021, supplemented by forward citation searching and hand-searching reference lists. Eligibility criteria were observational studies of frailty (using any measure) in adults (>18 years) with COPD, any setting (community, outpatient, inpatient, rehabilitation, residential care) assessing frailty prevalence, trajectories, or association with health-related outcomes. Study quality was assessed using Newcastle-Ottawa scale. Screening, quality assessment and data extraction performed independently by two reviewers. We synthesized results using narrative synthesis and, where heterogeneity allowed, random-effects meta-analyses.
Results
We identified 53 eligible studies using 11 frailty measures. Most common were frailty phenotype (32/53), frailty index (5/53) and Kihon checklist (4/53). Prevalence varied between frailty definitions, setting, and age of study population. Using the frailty phenotype, median prevalence was 12.5% in community studies. Prevalence was higher using other measures, and in inpatients, pulmonary rehabilitation and residential care settings. Frailty in COPD is dynamic, with airflow limitation, dyspnoea, and exacerbation frequency associated with worsening. Improvements in frailty status were observed following pulmonary rehabilitation. Frailty was associated with mortality (5/7 studies), COPD exacerbation (7/11), and hospital admission (3/4). Using frailty phenotype, pooled hazard ratio for mortality was 1.80 (95% CI 1.24–2.63) and pooled incident rate ratios were 1.42 (0.94–2.17) for COPD exacerbation and 1.46 (1.10–1.92) for hospitalization. Frailty was cross-sectionally associated with airflow limitation (11/14), dyspnoea (15/16), COPD severity scores (10/12), poorer QOL (3/4) and disability (1/1).
Conclusion
Frailty is a common and dynamic state in COPD, associated with adverse outcomes. However, frailty also appears responsive to intervention. A nuanced understanding of frailty identification, prognosis, and reversibility is required to allow appropriate individualization of COPD care.
