Abstract
Objectives: To explore obesity prevalence and its association with dietary patterns among Tibetan pastoralists during the urbanization transition in Qinghai Province. Methods: Using an open cohort study design, 1 003 subjects were enrolled at baseline in 2018, 599 were followed up, and 1 012 were newly recruited in 2022. A total of 1 913 adults over 18 years were included in the study, and a questionnaire survey and health examination were conducted. Factor analysis was used to identify dietary patterns, and a mixed-effects model was used to analyze the association between dietary patterns and obesity. Results: From 2018 to 2022, the prevalence rates of overweight, obesity, and central obesity were 27.6%, 33.8%, and 54.6%, respectively. Age-sex-standardized prevalence of obesity and central obesity increased. Three dietary patterns were identified: the modern pattern was characterized by frequent consumption of pork, poultry, processed meat, fresh fruits, sugary drinks, salty snacks, etcetera; the urban pattern was characterized by frequent consumption of refined carbohydrates, beef and mutton, vegetables and eggs, etcetera; and pastoral pattern featured frequent consumption of tsamba, Tibetan cheese, buttered/milk tea, and whole-fat dairy products. After adjusting for demographic characteristics, socioeconomic status, and lifestyle factors, compared with the T1, subjects in the T3 of urban pattern scores were more likely to be overweight (OR=2.09, 95%CI: 1.10-3.95) and overweight/obese (OR=1.23, 95%CI: 1.00-1.51), whereas those in the T3 of pastoral pattern scores had a lower risk of overweight (OR=0.45, 95%CI: 0.24-0.84), obesity (OR=0.81, 95%CI: 0.69-0.95), overweight/obesity (OR=0.75, 95%CI: 0.61-0.91) and central obesity (OR=0.58, 95%CI: 0.38-0.89). Conclusions: Prevalence of obesity and central obesity was high among Tibetan pastoralists during the urbanization transition. Urban dietary pattern was a risk factor for overweight and overweight/obesity, whereas pastoral dietary pattern was a protective factor for overweight, obesity, overweight/obesity, and central obesity. Tailored interventions are needed to improve local people's health.

Abstract
Objective: To analyze the change trend of underground dust concentration, the incidence and survival status of pneumoconiosis patients, and provide reference for improving the working environment of dust-exposed workers and the prevention and treatment of pneumoconiosis patients in the future. Methods: In February 2020, a retrospective investigation was conducted on the dust data of underground mining operations in a steel enterprise in Jiangsu Province from 1991 to 2019, and the case data of patients diagnosed with pneumoconiosis from 1956 to 2019 were collected. The time trends of the number of pneumoconiosis patients and dust concentration, the stage of pneumoconiosis and survival status of patients were analyzed. Results: From 1956 to 2019, a total of 241 patients with pneumoconiosis were diagnosed in the steel enterprise. From 1991 to 2019, the annual average dust concentration in the mine showed a downward trend as a whole. Compared with the transportation platform (14.28%, 1447/10132) , the average dust concentration exceeding rate of the mining platform (43.68%, 8415/19263) was significantly higher (χ(2)=2674.84, P<0.01) . The average age of pneumoconiosis patients was (73.54±10.42) years old, and the average working age of dust exposure was (21.41±8.68) years, of which 85 cases (35.27%) survived and 156 cases (64.73%) died. The main type of pneumoconiosis was silicosis (90.46%, 218/241) , and the main stage of pneumoconiosis was the stage I (96.68%, 233/241) ; The higher the stage of pneumoconiosis, the younger the diagnosis age (P<0.01) . The average survival time of patients was (27.264±1.982) years, and the median survival time was 28 years. The cumulative survival rates of patients with pneumoconiosis in different diagnosis time periods were significantly different (χ(2)=35.57, P<0.01) . Conclusion: The improved dust-proof measures have a significant effect on reducing the concentration of underground dust. We need to focus on the dust control of underground mining platforms and the treatment of patients with stage Ⅲ pneumoconiosis.

Abstract
Objective: Bioinformatics methods were used to mine differentially expressed genes (DEGs) and enriched signal pathways induced by chronic pesticide exposure, and explore its potential pathogenic mechanisms and key genes. Methods: In July 2021, high-throughput gene expression profile data related to pesticide toxicity was downloaded from Gene Expression Omnibus (GEO) database to obtain DEGs. The samples were from American male farm workers who had been exposed to pesticides for a long time and other industry workers. The functional enrichment analysis of GO, KEGG and Geme Set Enrichment Analysis (GSEA) were performed by R package clusterProfiler. STRING, Cytoscape and other tools were applied to construct and visualize the protein interaction network. With the help of MCODE and Cytohubba plugins, gene function modules were obtained, and hub gene was screened out. Results: 189 DEGs were screened from GSE30335 dataset, including 101 up-regulated genes and 88 down-regulated genes. The results of GO, KEGG and GSEA were mainly enriched in biological functions such as regulation of neuron projection development, regulation of locomotion, ribosomal protein synthesis, and pathways related to complex nervous system diseases such as Parkinson's disease. And the comprehensive screening showed that KLF1 was the hub gene of pesticide exposure, with a fold change of 0.456 (t=-3.82, P=0.021) . Conclusion: Long term exposure to pesticides results in the differential expression of multiple genes in the exposed population, which may be involved in the pathological changes of nervous system by down regulating KLF1 and related biological pathways.

Abstract
Objective: To understand the incidence of pneumoconiosis in the non-coal mining industry in Jiangsu Province, and provide reference for the prevention and control of pneumoconiosis in the non-coal mining industry. Methods: The data of 7019 newly diagnosed pneumoconiosis patients in non-coal mining industry in Jiangsu Province from January 1956 to December 2019 were collected through the Jiangsu Province Pneumoconiosis Follow-up Network Report System, including the gender of the pneumoconiosis patients, the name of the employer and the location, the industry classification of the employer, the duration of dust exposure in dust exposure, the name of occupational pneumoconiosis disease, the date of diagnosis of pneumoconiosis, etc. The collected case data of patients with pneumoconiosis were entered into the statistical software, and the characteristics of the patients' diagnosis time, region and industry were analyzed. Results: The number of confirmed pneumoconiosis patients in the non-coal mining industry in Jiangsu Province was mostly in 2007 (395 cases) , concentrated in Wuxi City (40.96%, 2875/7019) and Suzhou City (27.72%, 1946/7019) . The industries to which the patients belonged were mainly non-metallic mining and dressing (60.95%, 4278/7019) , and the most common type of pneumoconiosis was silicosis (96.40%, 6766/7019) . The patients were mainly stageⅠpneumoconiosis (61.33%, 4305/7019) . There were statistically significant differences in the mean age of diagnosis and the average duration of dust exposure among patients with different pneumoconiosis stages (P<0.01) . The differences in the average diagnosis age and the average duration of dust exposure of patients with different types of pneumoconiosis were statistically significant (P<0.05) , the mean age of diagnosis and the average duration of dust exposure of electric welders were the smallest, which were (44.92±7.74) years old and (17.38±10.15) years, respectively. Conclusion: The regional and industry distribution characteristics of new pneumoconiosis patients in the non-coal mining industry in Jiangsu Province are obvious, and attention should be paid to the treatment of pneumoconiosis patients with young diagnosed age and short duration of dust exposure, as well as the personal protection and health protection of front-line workers such as electric welders who are exposed to productive dust in a short period of time.

Abstract
Objective: To investigate the occupational hazard factors and exposure levels of workers during the construction of power transmission and transformation projects. Methods: Analysis and identification of occupational hazard factors were carried out for typical construction process of 6 power transmission projects and 3 substation projects in September 2018. The on-site occupational health investigation was carried out to detect and analyze the exposure levels of workers to occupational hazard factors. Results: The time weighted average concentration (C(TWA)) of crushing workers exposed to silica dust and welders exposed to welding fume in substation projects were 2.72 and 14.03 mg/m(3), respectively. The 8 h equivalent sound level results of exposure noise of carpenters in power transmission projects and crushing workers, reinforcement workers, carpenters, scaffolders, road builders in substation projects were 87.9, 92.5, 87.1, 92.5, 93.0 and 90.2 dB (A) , respectively. The 4-hour time equal energy frequency weighted vibration acceleration of hand-transmitted vibration of bricklayer in power transmission projects, bricklayer, general worker 3, road builder 1 and road builder 2 of substation projects were 5.36, 5.21, 5.28, 10.71 and 5.22 m/s(2), respectively. The effective irradiance of electric welding arc light of welders' limbs in power transmission projects and substation projects were 401.19, 319.68 μW/cm(2), respectively. All of the above exceeded the requirements of occupational exposure limits. The occupational radiation levels and exposure limits of hazardous chemical factors met the requirements of each post. Conclusion: During the construction of power transmission and transformation projects, the exposure levels of occupational hazard factors in multiple posts exceed the standard. The main responsibility of employers for occupational disease prevention and control should be implemented, and targeted comprehensive measures should be taken to reduce the exposure levels of occupational hazard factors of workers.

Abstract
Models considering hepatocellular carcinoma (HCC) complexity cannot be accurately replicated in routine cell lines or animal models. We aimed to evaluate the practicality of tissue slice culture by combining it with a cryopreservation technique. We prepared 0.3-mm-thick tissue slices by a microtome and maintained their cell viability using a cryopreservation technique. Slices were cultured individually in the presence or absence of regorafenib (REG) for 72 h. Alterations in morphology and gene expression were assessed by histological and genetic analysis. Overall viability was also analyzed in tissue slices by CCK-8 quantification assay and fluorescent staining. Tissue morphology and cell viability were evaluated to quantify drug effects. Histological and genetic analyses showed that no significant alterations in morphology and gene expression were induced by the vitrification-based cryopreservation method. The viability of warmed HCC tissues was up to 90% of the fresh tissues. The viability and proliferation could be retained for at least four days in the filter culture system. The positive drug responses in precision-cut slice culture in vitro were evaluated by tissue morphology and cell viability. In summary, the successful application of precision-cut HCC slice culture combined with a cryopreservation technique in a systematic drug screening demonstrates the feasibility and utility of slice culture method for assessing drug response.

Abstract
Objective: To understand the distribution and characteristics of suspected occupational chronic lead poisoning reported online by Jiangsu Province, and to track the final diagnosis of suspected cases. Methods: The suspected occupational chronic lead poisoning cases in Jiangsu Province reported online from 2014 to 2018 were collected as the survey objects. Based on the reporting of the Occupational Disease Report Card from January 1, 2014 to November 5, 2019, the distribution characteristics and reporting institutions of suspected cases and final confirmed cases were analyzed. Results: From 2014 to 2018, 312 cases of suspected occupational chronic lead poisoning were reported online in Jiangsu Province. There were significant differences in the number of online reported cases of occupational chronic lead poisoning, online reported cases of suspected occupational chronic lead poisoning and confirmed cases of suspected occupational chronic lead poisoning in different years (P<0.05) , especially in 2015. Among the suspected occupational lead poisoning cases reported online, 236 cases (75.6%) were male, mainly distributed in the manufacturing industry, and 246 cases (79.1%) were operators. All the suspected occupational chronic lead poisoning cases reported online were concentrated in private enterprises, 229 cases (73.4%) in small and medium-sized enterprises. The top three cities were Suqian with 111 cases (35.6%) , Yangzhou with 79 cases (25.3%) and Huai'an with 50 cases (16.0%) . From 2014 to 2018, 19 suspected cases of occupational chronic lead poisoning were finally confirmed in Jiangsu Province, with a diagnosis rate of 6.1%. Conclusion: The majority of suspected occupational chronic lead poisoning cases reported online in Jiangsu Province are men, manufacturing and small and medium-sized enterprises, and the final diagnosis rate of suspected occupational chronic lead poisoning cases reported online is low.

Abstract
Background: In recent years, deep learning has been widely used in a variety of ophthalmic diseases. As a common ophthalmic disease, meibomian gland dysfunction (MGD) has a unique phenotype in in-vivo laser confocal microscope imaging (VLCMI). The purpose of our study was to investigate a deep learning algorithm to differentiate and classify obstructive MGD (OMGD), atrophic MGD (AMGD) and normal groups. Methods: In this study, a multi-layer deep convolution neural network (CNN) was trained using VLCMI from OMGD, AMGD and healthy subjects as verified by medical experts. The automatic differential diagnosis of OMGD, AMGD and healthy people was tested by comparing its image-based identification of each group with the medical expert diagnosis. The CNN was trained and validated with 4,985 and 1,663 VLCMI images, respectively. By using established enhancement techniques, 1,663 untrained VLCMI images were tested. Results: In this study, we included 2,766 healthy control VLCMIs, 2,744 from OMGD and 2,801 from AMGD. Of the three models, differential diagnostic accuracy of the DenseNet169 CNN was highest at over 97%. The sensitivity and specificity of the DenseNet169 model for OMGD were 88.8 and 95.4%, respectively; and for AMGD 89.4 and 98.4%, respectively. Conclusion: This study described a deep learning algorithm to automatically check and classify VLCMI images of MGD. By optimizing the algorithm, the classifier model displayed excellent accuracy. With further development, this model may become an effective tool for the differential diagnosis of MGD.

Abstract
Globally, about two million people die from liver diseases every year. Liver transplantation is the only reliable therapy for severe end-stage liver disease, however, the shortage of organ donors is a huge limitation. Human hepatocytes derived liver progenitor-like cells (HepLPCs) have been reported as a novel source of liver cells for development of in vitro models, cell therapies, and tissue-engineering applications, but their functionality as transplantation donors is unclear. Here, a 3-dimensional (3D) co-culture system using HepLPCs and human umbilical vein endothelial cells (HUVECs) was developed. These HepLPC spheroids mimicked the cellular interactions and architecture of mature hepatocytes, as confirmed through ultrastructure morphology, gene expression profile and functional assays. HepLPCs encapsulated in alginate beads are able to mitigate liver injury in mice treated with carbon tetrachloride (CCL4), while alginate coating protects the cells from immune attack. We confirmed these phenomena due to HUVECs producing glial cell line-derived neurotrophic factor (GDNF) to promote HepLPCs maturation and enhance HepLPCs tight junction through MET phosphorylation. Our results display the efficacy and safety of the alginate microencapsulated spheroids in animal model with acute liver injury (ALF), which may suggest a new strategy for cell therapy.

Abstract
Occupational disease diagnosis standards are an important basis for occupational disease diagnosis, occupational health surveillance, occupational health supervision, occupational disease treatment, occupational disease disability assessment, and handling of occupational disease diagnosis disputes in conjunction with the "Occupational Disease Prevention and Control Law of the People's Republic of China". With the successive promulgation of the "Standardization Law of the People's Republic of China" and the "Administrative Measures on Health Standards", the establishment of a mandatory standard implementation evaluation mechanism has gradually been paid attention to. However, there is still a lack of systematic research on the evaluation of diagnostic criteria for occupational diseases. Therefore, this article combines the current status of the diagnostic standards for occupational diseases in China, and proposes reasonable suggestions on how to carry out the evaluation of the implementation of this type of standard in terms of evaluation methods and content.

Abstract
Objective: To analyze the protective effect of dust masks worn by super absorbent polymer (SAP) dust-exposed workers and the influence of each test exercise on the protective effect of mask. Methods: In March 2017, forty nine SAP dust-exposed workers in a large chemical enterprise were selected as subjects. The respirator fitness tester was used to test the protective effect of dust mask before and after training, and the influence of each test exercise on the protective effect of dust mask was analyzed. Results: After training, the qualified rate of dust mask protective effect of SAP dust-exposed workers was 95.92% (47/49) , which was significantly higher than that before training [63.31% (32/49) ], and the difference was statistically significant (χ2=14.69, P<0.01) . When the total protective effect was qualified, the fit factor (FF) decreased significantly when speaking aloud and bending down (Z=-2.59, -4.20, P<0.01) . The qualified rates of protective effect of each exercise were significantly different (χ2=42.70, P<0.01) , among which the qualified rates of deep breath was the highest (100.00%) , and the qualified rate of bending down was the lowest (70.21%) . Conclusion: Strengthening the training of workers to wear masks correctly is helpful to improve their respiratory protection efficiency. Under the condition that the total protective effect of dust masks is qualified, workers should try to avoid unnecessary actions, especially speaking aloud and bending down frequently.

Abstract
Abstract
Background
A variety of supraventricular arrhythmias (SVAs) may occur in patients with hypertrophic cardiomyopathy (HCM). The characteristics and long-term ablation outcomes of different types of SVAs in HCM have not been comprehensively investigated.
Methods
We retrospectively enrolled 101 consecutive symptomatic HCM patients with suspected arrhythmia from May 2010 to October 2020. The clinical features and ablation outcomes of patients with SVAs were further analyzed.
Results
Seventy-eight patients had SVAs, consisting of 50 (64.1%) atrial fibrillation (AF), 16 (20.5%) atrial flutter (AFL), 15 (19.2%) atrioventricular reentrant tachycardia (AVRT), 11 (14.1%) atrial arrhythmia (AT), and 3 (3.8%) atrioventricular nodal reentrant tachycardia (AVNRT). Thirty-four patients underwent catheter ablation including 14 for AF, 9 for AVRT, 6 for AFL, 3 for AVNRT, 1 for both AF and AFL, and 1 for both AF and AVRT. They were followed up for a median (interquartile range) of 58.5 (82.9) months. There were no recurrences for patients with non-AF SVAs. For patients with AF, the 1- and 7-year AF-free survival were 87.5% and 49.5%, respectively. A ROC analysis revealed that a greater left ventricular end-diastolic dimension (LVEDD) was associated with higher recurrence of AF with an optimum cutoff value of 47mm (c-statistic = 0.91, p=0.011, sensitivity = 1.00, specificity = 0.82). In Kaplan-Meier analysis, patients with LVEDD ≥47mm had worse AF-free survival (log-rank p=0.014).
Conclusions
AF is the most common SVA in HCM, with AFL, AVRT, AT, and AVNRT ranking the second to the last according to the prevalence. The long-term catheter ablation outcome for non-AF SVAs in HCM is satisfying. A greater LVEDD predicts AF recurrence after catheter ablation in patients with HCM.

Abstract
Clinical advancement of the bioartificial liver is hampered by the lack of expandable human hepatocytes and appropriate bioreactors and carriers to encourage hepatic cells to function during extracorporeal circulation. We have recently developed an efficient approach for derivation of expandable liver progenitor-like cells from human primary hepatocytes (HepLPCs). Here, we generated immortalized and functionally enhanced HepLPCs by introducing FOXA3, a hepatocyte nuclear factor that enables potentially complete hepatic function. When cultured on macroporous carriers in an air-liquid interactive bioartificial liver (Ali-BAL) support device, the integrated cells were alternately exposed to aeration and nutrition and grew to form high-density three-dimensional constructs. This led to highly efficient mass transfer and supported liver functions such as albumin biosynthesis and ammonia detoxification via ureagenesis. In a porcine model of drug overdose-induced acute liver failure (ALF), extracorporeal Ali-BAL treatment for 3 hours prevented hepatic encephalopathy and led to markedly improved survival (83%, n = 6) compared to ALF control (17%, n = 6, P = 0.02) and device-only (no-cell) therapy (0%, n = 6, P = 0.003). The blood ammonia concentrations, as well as the biochemical and coagulation indices, were reduced in Ali-BAL-treated pigs. Ali-BAL treatment attenuated liver damage, ameliorated inflammation, and enhanced liver regeneration in the ALF porcine model and could be considered as a potential therapeutic avenue for patients with ALF.

Abstract
Objective: To investigate the clinical features and effect of prognostic factors in patients with different pathological types of non-Hodgkin lymphoma-associated hemophagocytic lymphohistiocytosis. Methods: We collected and analyzed the clinical data of 89 patients with non-Hodgkin lymphoma-associated hemophagocytic lymphohistiocytosis who were treated at Huadong Hospital from March 2013 to May 2020. The data were analyzed via log-rank and Cox multivariate analyses. Results: The median overall survival time of the 89 cases was 10.2 months. Patients with B-cell lymphoma-associated hemophagocytic lymphohistiocytosis did not reach the median overall survival time. The median overall survival times of T-cell lymphoma-associated hemophagocytic lymphohistiocytosis and NK-cell lymphoma-associated hemophagocytic lymphohistiocytosis were 10.2 and 3.0 months, respectively. The pathological type of non-Hodgkin lymphoma (OS: P=0041, PFS: P=0.015) , ECOG score ≥ 3 (OS: P=0.031, PFS: P=0.030) , hematopoietic stem cell transplantation (OS: P=0.005, PFS: P=0.040) , lymphadenopathy (OS: P=0.007, PFS: P=0.012) , and splenomegaly (OS: P=0.276, PFS: P=0.324) were related to the overall survival and progression-free survival of patients with non-Hodgkin lymphoma-associated hemophagocytic lymphohistiocytosis. Splenectomy could improve the prognosis of patients with lymphoma-associated hemophagocytic lymphohistiocytosis, especially T-cell lymphoma-associated hemophagocytic lymphohistiocytosis. Conclusion: The clinical characteristics of patients with different pathological types of non-Hodgkin lymphoma-associated hemophagocytic lymphohistiocytosis were similar but were different in the overall survival rate and the effect of prognostic factors. We suggested that patients with non-Hodgkin lymphoma-associated hemophagocytic lymphohistiocytosis should receive more than combined chemotherapy. To improve the prognosis and survival rate of patients, those with B-cell lymphoma-associated hemophagocytic lymphohistiocytosis and NK-cell lymphoma-associated hemophagocytic lymphohistiocytosis promptly require hematopoietic stem cell transplantation. Moreover, patients with T-cell lymphoma-associated hemophagocytic lymphohistiocytosis should consider splenectomy.

The combined induction of liver progenitor cells and the suppression of stellate cells by small molecules reverts chronic hepatic dysfunction. Am J Cancer Res 2021; 11:5539-5552.

Abstract
Rationale: We developed a cocktail of soluble molecules mimicking the in vivo milieu supporting liver regeneration that could convert mature hepatocytes to expandable liver progenitor-like cells in vitro. This study aimed to induce endogenous liver progenitor cells by the administration of the soluble molecules to provide an alternative approach for the resolution of liver fibrosis. Methods: In vitro cultured hepatocyte-derived liver progenitor-like cells (HepLPCs) were transplanted into CCL4-treated mice to investigate the therapeutic effect against liver fibrosis. Next, we used HGF in combination with a cocktail of small molecules (Y-27632, A-83-01, and CHIR99021 (HACY)) to induce endogenous CD24+ liver progenitor cells and to inhibit the activation of hepatic stellate cells (HSCs) during CCL4-induced hepatic injury. RNA sequencing was performed to further clarify the features of HACY-induced CD24+ cells compared with CCL4-induced CD24+ cells and in vitro derived HepLPCs. Finally, we evaluated the expansion of HACY-induced CD24+ cells in human hepatocyte-spheroids from fibrotic liver tissues. Results: HepLPCs exhibited the capacity to alleviate liver fibrosis after transplantation into CCL4-treated mice. The in vivo administration of HACY not only induced the conversion of mature hepatocytes (MHs) to CD24+ progenitor cells but prevented the activation of HSCs, thus leading to enhanced improvement of liver fibrosis in CCL4-treated mice. Compared to CD24+ cells induced by CCL4 alone, HACY-induced CD24+ cells retained an enhanced level of hepatic function and could promote the restoration of liver function that exhibited comparable gene expression profiles with HepLPCs. CD24+ cells were also observed in human liver fibrotic tissues and were expanded in three-dimensional (3D) hepatic spheroids in the presence of HACY in vitro. Conclusions: Hepatocyte-derived liver progenitor-like cells are crucial for liver regeneration during chronic hepatic injuries. The administration of HACY, which allowed the induction of endogenous CD24+ progenitor cells and the inactivation of HSCs, exerts beneficial effects in the treatment of liver fibrosis by re-establishing a balance favoring liver regeneration while preventing fibrotic responses.

Abstract
Importance The role of locoregional radiotherapy in patients with de novo metastatic nasopharyngeal carcinoma (mNPC) is unclear. Objective To investigate the efficacy and safety of locoregional radiotherapy in de novo mNPC. Design, Setting, and Participants Patients with biopsy-proven mNPC, who demonstrated complete or partial response (RECIST v1.1) following 3 cycles of cisplatin and fluorouracil chemotherapy, were enrolled. Eligible patients were randomly assigned (1:1) to receive either chemotherapy plus radiotherapy or chemotherapy alone. Overall, 126 of 173 patients screened were eligible to the study, and randomized to chemotherapy plus radiotherapy (n = 63) or chemotherapy alone (n = 63). Median (IQR) follow-up duration was 26.7 (17.2-33.5) months. Interventions The chemotherapy regimens were fluorouracil continuous intravenous infusion at 5 g/m2 over 120 hours and 100 mg/m2 intravenous cisplatin on day 1, administered every 3 weeks for 6 cycles. Patients assigned to the chemotherapy plus radiotherapy group received intensity-modulated radiotherapy (IMRT) after chemotherapy. Main Outcomes and Measures The primary end point of the study was overall survival (OS). The secondary end point was progression-free survival (PFS) and safety. Results Overall, 126 patients were enrolled (105 men [83.3%] and 21 women [16.7%]; median [IQR] age, 46 [39-52] years). The 24-month OS was 76.4% (95% CI, 64.4%-88.4%) in the chemotherapy plus radiotherapy group, compared with 54.5% (95% CI, 41.0%-68.0%) in the chemotherapy-alone group. The study met its primary end point of improved OS (stratified hazard ratio [HR], 0.42; 95% CI, 0.23-0.77; P = .004) in favor of chemotherapy plus radiotherapy. Progression-free survival was also improved in the chemotherapy plus radiotherapy group compared with the chemotherapy-alone group (stratified HR, 0.36; 95% CI, 0.23-0.57). No significant differences in acute hematological or gastrointestinal toxic effects were observed between the treatment arms. The frequency of acute grade 3 or higher dermatitis, mucositis, and xerostomia was 8.1%, 33.9%, and 6.5%, respectively, in the chemotherapy plus radiotherapy group. The frequency of late severe grade 3 or higher hearing loss and trismus was 5.2% and 3.4%, respectively, in the chemotherapy plus radiotherapy group. Conclusions and Relevance In this randomized clinical trial, radiotherapy added to chemotherapy significantly improved OS in chemotherapy-sensitive patients with mNPC. Trial Registration ClinicalTrials.gov Identifier: NCT02111460.

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.

Abstract
Objective: To investigate the features, changing trend, and rules of pneumoconiosis in Jiangsu Province, China, as well as the health status of patients with pneumoconiosis. Methods: From July to October 2019, the patients with pneumoconiosis, reported up to the end of 2018 in Jiangsu Province, were enrolled as respondents, and follow-up and retrospective investigation were performed. A total of 24405 patients with pneumoconiosis were investigated, and related data were collected from the monitoring system of cause of death for residents, pneumoconiosis network reporting system, occupational disease diagnosis institution, management institutions for the reporting of occupational diseases, and related residents' committee or village committee. The patients with pneumoconiosis, who had been reported, were followed up by telephone or on-site visit to obtain the information on their conditions. A descriptive analysis was performed for age of onset, working years, sex, category of industry, type of pneumoconiosis, annual disease onset, geographic distribution, and medical security. Results: Among the 24405 patients, a male/female ratio was 16.81∶1. Of all 24405 patients, 15948 (65.35%) had stage 1 pneumoconiosis, 5289 (21.67%) had stage 2 pneumoconiosis, and 1637 (6.71%) had stage 3 pneumoconiosis. The mean working years for dust exposure was 16.25±9.95 years for all patients, and the mean working years for dust exposure was 15.80±9.95 years for patients with stage 1 pneumoconiosis, 17.82±9.80 years for patients with stage 2 pneumoconiosis, and 16.31±9.90 years for patients with stage 3 pneumoconiosis. The highest number of cases of pneumoconiosis was reported in Wuxi (5744 cases, accounting for 23.54%) , followed by Zhenjiang (4160 cases, accounting for 17.05%) , Xuzhou (3851 cases, accounting for 15.78%) , Yancheng (3340 cases, accounting for 13.69%) , and Suzhou (2948 cases, accounting for 12.08%) . Major types of pneumoconiosis included silicosis (15392 cases, accounting for 63.07%) and coal workers' pneumoconiosis (5253 cases, accounting for 21.52%) . In this survey, 21115 completed follow-up, among whom 15924 survived and 5191 died, 15924 patients with pneumoconiosis survived, among whom 7461 (46.85%) had an age of ≥70 years and 2515 (15.79%) were exposed to dust for 5-9 years. The industries involved were mainly coal mining and washing industry (5687 cases, accounting for 35.71%) and public management, social security, and social organization (3349 cases, accounting for 21.03%) ; in terms of security, 7999 patients (50.23%) were covered by occupational injury insurance, 946 (5.94%) were compensated by employers, 4537 (28.49%) were covered by basic medical insurance for urban and rural residents, 1590 (9.98%) were covered by critical illness insurance, and 5458 (34.28%) were covered by other types of social security, such as medical assistance and poverty relief.

Abstract
Living tumors are of great scientific value for clinical medicine and basic research, especially for drug testing. An increasing number of drug tests fail due to the use of imperfect models. The aim of the present study was to develop a novel method combining vitrification-based cryopreservation of tumor biopsies and precision-cut slice cultivation for the assessment of anticancer drug responses. Biological characteristics of rectal cancer liver metastasis biopsies could be retained by vitrification-based cryopreservation. The patient-derived xenograft models were successfully established using both fresh and warmed biopsy tissues. Precision-cut slicing provided a similar three-dimensional architecture and heterogeneity to the original tumor. The positive drug responses in the xenograft model were consistent with those in precision-cut slice cultures in vitro. The present study demonstrated that live tumor biopsies could be preserved using vitrification-based cryopreservation. The warmed tissues developed xenograft tumors, which were also useful for either in vivo or in vitro anticancer drug testing. Precision-cut slices derived from the warmed tissues provided an efficient tool to assess anticancer drug response in vitro.

Abstract
Objective: To analyze the prevalence of pneumoconiosis and civil aid and medical care among Xiangyang-Chongqing railway construction workers in Chongqing from 2011 to 2018, so as to provide scientific basis for prevention and control of pneumoconiosis. Methods: The Chongqing database of Xiangyang-Chongqing railway construction workers cases from 2011 to 2018 were subjected to systematic collected. SPSS 18.0 was adopted for statistical description and analysis. Results: From 2011 to 2018, a total of 7031 silicosis cases were diagnosed, and 5827 cases were existed, including 4056 cases of stage I, 1491 cases of stage II, and 280 cases of stage III. The cases were concentrated in the area along the southwest to northeast of Chongqing. The diagnosis age of silicosis patients was mainly 60~64 years old (69.73%) . Most silicosis cases were the drill workers and the stone workers. The exposure time of silicosis patients was short and concentrated in 3 years. The 5827 cases of pneumoconiosis in the Xiangyang-Chongqing railway were all treated with special civil aid and medical care for pneumoconiosis in the Xiangyang-Chongqing railway. Conclusion: The prevalence of silicosis among workers who participated in Xiangyang-Chongqing railway construction remained serious. Civil aid and medical care covers all silicosis patients. Occupational health surveillance for silicosis and assistance should be carried out in these workers.

Abstract
Objective: To investigate the living conditions, insurance coverage, and assistance of pneumoconiosis patients diagnosed in Chongqing from May 2006 to May 2018. Methods: A cross-sectional survey was conducted in July 2018, and 40 890 pneumoconiosis patients from occupational diseases report management agency were obtained. 34 625 cases meeting the inclusion criteria were investigated, and descriptive statistical analysis was performed on the data. Results: There were 34 625 cases of pneumoconiosis patients alive in Chongqing, and 22730 (65.6%) had participated in work-related injury insurance, 6 308 (18.2%) had participated in basic medical insurance for urban employees which were still effective. 27 056 (78.1%) had participated in cooperative insurance for urban and rural residents which were still effective. 4 393 (12.7%) received assistance for the residents in need in urban and rural areas. 5827 (16.8%) benefited the policy of "Xiangyu Railway". There were 7 961 cases (2.4%) whose work-related injury insurance had expired did not get one-off compensation, and did not receive any assistance. Conclusion: Most of the patients with pneumoconiosis in Chongqing obtained protection in terms of work-related injury insurance, medical insurance, civil assistance and poverty alleviation to a certain extent, but the strength of the guarantee is not enough. Patients with pneumoconiosis might suffer from poverty caused by illness. It is recommended to improve the system of work-related injury insurance benefits, establish special funds for pneumoconiosis patients, strengthen health education and health promotion for pneumoconiosis patients, and strengthen the management of pneumoconiosis patients.

Abstract
Objective: To analyze the characteristics and patterns of occupational pneumoconiosis in Jiangsu Province, China, from 2006 to 2017, and to provide a scientific basis for government departments to develop effective interventions and preventive strategies against occupational pneumoconiosis. Methods: The data of 9327 patients with occupational pneumoconiosis were retrieved from the online report of occupational pneumoconiosis in Jiangsu Province from 2006 to 2017. Excel worksheet and SPSS 20.0 software were used to organize and analyze the data, respectively. An epidemiological statistical analysis was performed on age of onset, length of dust exposure, type of work, industry category, type of pneumoconiosis, annual incidence of pneumoconiosis, regional distribution, enterprise scale, and economic category in those patients. Results: A total of 9 327 patients with occupational pneumoconiosis were reported in Jiangsu Province from 2006 to 2017. In those patients, 8 559 were newly diagnosed and 768 had advanced disease. The male-female ratio was 16.34:1.Patients with stage I pneumoconiosis(6 994, 74.99%) were dominant in all the patients. The mean age of onset and length of dust exposure were 58.5±10.7 and 15.3±10.9 years, respectively. Most of the patients (6 012, 64.46%) had an age of onset between 50 and 69 years. For the length of dust exposure, the highest percentage was observed in patients exposed for no more than 5 years (2 231, 23.92%).The largest number of patients diagnosed with pneumoconiosis(1 200, 12.87%) was reported in 2010. Most of the patients(7 012, 75.18%) were from four cities, i.e, Wuxi (2 090, 22.41%), Yancheng (1 987, 21.30%), Suzhou (1 552, 16.64%), and Xuzhou (1 383, 14.83%). In all the patients, the incidence of silicosis (6791, 72.81%) was highest, followed by coal worker pneumoconiosis (1 364, 14.62%) and electric welder pneumoconiosis (563, 6.04%).Pneumoconiosis complicated by tuberculosis was found in 28 (0.3%) patients.A total of 1616 (17.33%) patients were reported in health, social security, and social welfare industries, while 1474 (15.80%) patients worked for coal mining and washing. Rock drillers (2 818, 30.21%) were dominant in those patients.State-owned economic enterprises reported the largest number of patients(5 441, 58.34%).Patients from small enterprises (4 323, 46.35%) had the highest percentage. Conclusion: Pneumoconiosis is an occupational disease with a high incidence in Jiangsu Province. Pneumoconiosis patients show an industry- and job-centered distribution. The length of dust exposure is decreasing.

Abstract
Abstract Objective To study the expressions of transforming growth factor-β1 (TGF-β1) and EⅢA-fibronectin (EⅢA-FN) at different time points of antemortem injury, antemortem injury postmortem expression and postmortem injury and to explore their application value in wound age estimation. Methods A model of rat skeletal muscle contusion was established. The rats were randomly divided into normal control group (n=5), antemortem contusion group (n=40), antemortem contusion postmortem expression group (n=110) and postmortem injury group (n=25). The expressions of TGF-β1 and EⅢA-FN after rat skeletal muscles antemortem contusion were detected with immunohistochemical staining. Expression changes of TGF-β1 and EⅢA-FN mRNA in each group were analyzed with real-time fluorescence quantitative PCR. Results Immunohistochemical staining results showed that a large number of polymorphonuclear leukocyte, mononuclear cells and fibroblastic cells showed a strong expression of TGF-β1 in wounded zones 12 h-14 d after antemortem contusion. EⅢA-FN was mainly distributed in the extracellular matrix, 3 to 7 d post-traumatic. Real-time fluorescence quantitative PCR results showed that TGF-β1 and EⅢA-FN mRNA in antemortem injury group reached the peak at 3 and 5 d post-traumatic respectively. The expressions of TGF-β1 and EⅢA-FN mRNA in antemortem contusion postmortem expression group peaked at 6 h and 12 h postmortem. The expression of TGF-β1 and EⅢA-FN mRNA in postmortem injury group 0.5-12 h postmortem was significantly lower than those of the normal control group and the antemortem contusion group. Conclusion TGF-β1 and EⅢA-FN might become a reference index for skeletal muscle wound age estimation.

Abstract
The most essential tools for studying drug hepatotoxicity, liver diseases, and bioartificial livers have always been models that can recapitulate liver physiology in vitro. The liver progenitor cell line HepaRG represents an effective surrogate of the primary hepatocyte. However, the differentiation of HepaRG relies on long-term induction using a high concentration of dimethyl sulfoxide (DMSO), which may compromise the research of drug metabolism and restrict the applicability of this hepatic model. Here, we present a novel hepatic maturation medium (HMM) for the differentiation of HepaRG, which is based on a cocktail of soluble molecules that mimick the in vivo environment. We showed that HMM could rapidly (about nine days) induce HepaRG differentiation into polarized hepatocytes with maturely metabolic functions. In addition, under three-dimensional culture conditions, the hepatic spheroids showed multiple liver functions and toxicity profiles close to those of primary human hepatocytes (PHH). Our work demonstrates the utility of HMM as an alternative to the DMSO-dependent differentiation protocol for HepaRG; moreover, these results facilitate the application of HepaRG.

Abstract
Objective: To analyze the epidemiological characteristics and the harmfulness situation of pneumoconiosis notified in Chongqing from 2011 to 2015, so as to provide scientific basis for prevention and control of pneumoconiosis. Methods: The Chongqing database of new cases of pneumoconiosis reported from 2011 to 2015 was subjected to systematic arrangement. SPSS 18.0 was adopted for statistical description and trend test. Results: From 2011 to 2015 a total of 24903 new cases of pneumoconiosis were diagnosed, including I (16 294 cases, 65.43%), II (6 520 cases, 26.18%), III (2 089 cases, 8.39%). Of all patients, 98.93% were cases of coal-workers' pneumoconiosis and silicosis. 13 383 (53.74%) were coal-workers' pneumoconiosis cases, and 11 253 (45.19%) were silicosis cases. The pneumoconiosis cases were distributed mainly in Fengjie County (3 329 cases, 13.37%), Yongchuan District (2 849 cases, 11.44%), and Chengkou County (2 584 cases, 10.38%). Most cases were centered in mining industry (17 575 cases, 70.57%) and construction industry (6 613 cases, 26.56%). The median lengths of service at the onsets of new cases of pneumoconiosis, silicosis, coal-workers' pneumoconiosis were 7.0, 3.0, and 16.0 years, respectively. The median age at the onset of pneumoconiosis was shortened from 2011 to 2015. The median ages at the onsets of new cases of pneumoconiosis, silicosis, coal-workers' pneumoconiosis were 53.0, 62.0, and 49.0 years, respectively. Conclusion: The research results showed obvious diseases, regions and industries distribution. The median length of service at the onset of pneumoconiosis was on the low side, and a shortening trend showed in age at the onset of pneumoconiosis. Based on the epidemiological characteristics of pneumoconiosis, the prevention and control of pneumoconiosis should be enhanced in key industries such as mining industry and construction industry.

Abstract
Objective: To investigate the reproductive health status of female workers in petrochemical industry, and to provide a reference for improving reproductive health status and developing preventive and control measures for female workers in petrochemical industry. Methods: A face-to-face questionnaire survey was performed from January to October, 2016. The Questionnaire on Women's Reproductive Health was used to investigate the reproductive health of female workers in petrochemical industry. The multivariate logistic regression model was used to identify the influencing factors for reproductive health of female workers in petrochemical industry. Results: Among the 7485 female workers, 1 268 (40.9%) had abnormal menstrual period, 1 437 (46.4%) had abnormal menstrual volume, 177 (28.5%) had hyperplasia of mammary glands, and 1 807 (24.6%) had gynecological inflammation. The reproductive system diseases in female workers in petrochemical industry were associated with the factors including age, marital status, education level, unhealthy living habits, abortion, overtime work, work shift, workload, video operation, occupational exposure, positive events, and negative events, and among these factors, negative events (odds ratio[OR]= 1.856) , unhealthy living habits (OR=1.542) , and positive events (OR=1.516) had greater impact on reproductive system diseases. Conclusion: Many chemical substances in the occupational environment of petrochemical industry can cause damage to the reproductive system, which not only affects the health of the female workers, but also poses potential threats to the health of their offspring. Occupational exposure, unhealthy living habits, overtime work, and work shift have great influence on reproductive system diseases in female workers.

Abstract
Objective: To investigate the incidence of occupational diseases in a province of China during the period of "Twelfth Five-Year Plan" , and to analyze the features of disease spectrum, the characteristics of regional and industrial distribution, and incidence trend. Methods: Data (2011-2015) were collected from the Information System of Occupational Diseases and Occupational Health to analyze the reported cases of occupational diseases during the period of "Twelfth Five-Year Plan". A statistical analysis was performed to identify the characteristics of the disease distribution in terms of sex, age, working years, enterprise type, enterprise scale, and region, as well as the incidence trend. Results: The overall incidence of occupational diseases in this province fluctuated and decreased gradually. There were a total of 5036 new cases of occupational diseases during the period of "Twelfth Five-Year Plan" ; 89.45% of them were male, and 69.78% of them were aged 40-69 years; the most frequently seen occupational diseases were pneumoconiosis (72.48%) and ear, nose, throat, and oral diseases (7.23%). Most cases of pneumoconiosis occurred after 5-10 years of exposure, and other occupational diseases usually developed within 10 years of exposure. New cases of occupational diseases were often seen in small and micro enterprises, as well as Wuxi, Suzhou, and Yancheng. Conclusion: During the period of "Twelfth Five-Year Plan" , the incidence of occupational diseases in this province decreased gradually, indicating improved control of occupational diseases, but we still need to pay attention to the high-risk population (male, aged over 40 years) , as well as the prevention of occupational noise-induced hearing loss, and to strengthen the supervision of small and micro enterprises.

Abstract
OBJECTIVE To evaluate the survival rate and peri-implant clinical parameters of Locking-Taper implants in patients having lost their teeth due to non-periodontitis (NP) reasons, chronic periodontitis (CP) and aggressive periodontitis (AgP). METHODS In the study, 145 subjects were installed with 315 Bicon Locking-Taper implants and followed up for 1-5 years. The subjects and implants were classified into three groups, tooth loss by NP, CP and AgP. NP included 44 subjects with 100 implants, CP 70 subjects with 132 implants and AgP 31 subjects with 83 implants. Periodontal parameters before subgingival scaling and root planning (T0), at the end of active periodontal therapy (T1) and at the time of last recall (T2) were recorded. Right after the installation of final restoration and at the time of last recall (T2), peri-implant probing parameters were recorded. RESULTS After active periodontal therapy, mean probing depth (PD) in CP and AgP were reduced from 4.05 mm, 5.20 mm at T0 to 3.07 mm, 2.96 mm at T1 (P<0.001, P<0.001), (PD≥6 mm)% were reduced from 33.2%, 58.5% at T0 to 14.4%, 10.5% at T1 (P<0.001, P<0.001). The periodontal parameters remained stable at T2 compared with T1 (P>0.05). Cumulative survival rates of implants in NP, CP and AgP were 100%, 97.6% and 100% for 1-5 years' follow-ups with no statistical significance found. At T2, mean implant PD was 2.78 mm, 2.96 mm and 2.97 mm in NP, CP and AgP, with NP significantly lower than the other two groups (P=0.006, P=0.01). The percentage of implant sites with PD≥6 mm was 3.7% in CP and 4.8% in AgP, both significantly higher than NP (P=0.003, P<0.001). 8.4% implant sites showed at least 2 mm deeper than those at prosthesis installation were found in CP group, significantly higher than NP (4.3%, P=0.003). CONCLUSION Periodontal conditions of patients having lost their teeth for chronic and aggressive periodontitis were significantly improved after active periodontal therapy and remained stable during 1-5 years. Short-term survival rates of Locking-Taper implants in patients treated for CP and AgP was no less than those who lost their teeth for non-periodontitis reasons. More sites with increasing peri-implant probing depth were found in CP and AgP patients, compared with NP.

Abstract
Sr4Ru3O10, the n = 3 member of the Ruddlesden-Popper type ruthenate Srn+1RunO3n+1, is known to exhibit a peculiar metamagnetic transition in an in-plane magnetic field. However, the nature of both the temperature- and field-dependent phase transitions remains as a topic of debate. Here, we have investigated the magnetic transitions of Sr4Ru3O10 via single-crystal neutron diffraction measurements. At zero field, we find that the system undergoes a ferromagnetic transition with both in-plane and out-of-plane magnetic components at Tc ≈ 100 K. Below T * = 50 K, the magnetic moments incline continuously toward the out-of-plane direction. At T = 1.5 K, where the spins are nearly aligned along the c axis, a spin reorientation occurs above a critical field Bc, giving rise to a spin component perpendicular to the plane defined by the field direction and the c axis. We suggest that both the temperature- and field-driven spin reorientations are associated with a change in the magnetocrystalline anisotropy, which is strongly coupled to the lattice degrees of freedom. This study elucidates the long-standing puzzles on the zero-field magnetic orders of Sr4Ru3O10 and provides new insights into the nature of the field-induced metamagnetic transition.

Abstract
Objective: To investigate the significance of circulating tumor cells (CTC) in squamous cell carcinoma of the head and neck (HNSCC). Methods: Twenty-four patients with HNSCC treated between October 2016 and July 2017 in our department were selected (experimental group), including 23 males and 1 females, aged 47-81 years. There were 14 cases of squamous cell carcinoma of larynx and 10 cases of hypopharynx, including I-Ⅱ stage (5 cases) and Ⅲ- Ⅳ stage (19 cases). All patients were primary and/or relapsed after treatment. Nine healthy volunteers were selected as control group. A novel in vivo capture technique (CellCellector system) was used to detect CTC. SPSS23.0 was used for statistical analysis. Results: The total capture rate of CTC in patients with HNSCC before treatment was 70.8% (17/24), with 40% (2/5) for patients at I-Ⅱ stage, and 78.9% (15/19) for patients at Ⅲ- Ⅳ stage, and was 0 in patients of control group. The total capture rate of CTC in patients with HNSCC after treatment was 50% (8/16). There was no significant correlation between CTC and age, sex, location of tumor or lymph node metastasis (P>0.05). CTC was related to tumor staging and tumor differentiation (P<0.05). The positive rate of EGFRVⅢ in CTC was 26.3% (5/19). Conclusions: The CellCollector system is a very efficient way of detecting CTC, and CTC plays an important role in the occurrence, progression and metastasis of HNSCC.

Abstract
Tumor tissue has great clinical and scientific value which relies highly on the proper preservation of primary materials. Conventional tumor tissue cryopreservation using slow-freezing method has yielded limited success, leading to significant cell loss and morphological damage. Here we report a standardized vitrification-based cryopreservation method, by which we have successfully vitrified and warmed 35 intrahepatic cholangiocarcinoma (ICC) tissues with up to 80% viability of the fresh tumor tissues. Cryopreserved ICC tissue could generate patient-derived xenografts (PDXs) with take rates of 68.2% compared to 72.7% using fresh tumor tissues. Histological and genetic analyses showed that no significant alterations in morphology and gene expression were introduced by this cryopreservation method. Our procedure may facilitate collection, long-time storage and propagation of cholangiocarcinoma or other tumor specimens for (pre)clinical studies of novel therapies or for basic research.

Abstract
Objective:This paper discusses the expression and significance of CD4⁺CD25⁺ Tregs and Foxp3 in peripheral blood of patients with head and neck squamous cell carcinoma. Method:We have collected 40 cases of head and neck squamous cell carcinoma patients with newly diagnosed or relapse after treatment, all of them underwent surgery, 39 males and 1 females, aged 41-79 years, in our department from January 2014 to December 2015. At the same time, 10 healthy volunteers are enrolled as control group. 2 ml peripheral blood has been detected by flow cytometry, and the ratio of CD4⁺CD25⁺/CD4⁺ and CD4⁺CD25⁺Fxop3⁺/CD4⁺ are calculated, respectively. SPSS 23.0 is used for statistical analysis. Result:CD4⁺CD25⁺ Tregs is highly expressed in head and neck tumors, compared with that in the healthy control, and the difference is statistically significant (P<0.01). There is significant difference between the early and late stage (P<0.05). The positive rate of Foxp3+ is higher in CD4⁺CD25⁺ Tregs positive cells than in control group (P<0.01). The difference of positive rate between late stage and early stage head and neck tumors is statistically significant (P<0.05). There is a significant positive correlation between CD4⁺CD25⁺ Tregs and Foxp3 (r=0.95). Conclusion:CD4⁺CD25⁺ Tregs and Foxp3 are highly expressed in the peripheral blood of patients with head and neck squamous cell carcinoma. Through the inhibition of the immune system in patients with head and neck squamous cell carcinoma, the development of carcinoma were promoted.

Abstract
Objective:The aim of this study is to detect the expression of EGFRvⅢ and CXCR4 in HNSCC and to explore its possible mechanism. Method:We selected 60 cases of HNSCC from May 2013 to November 2016 in our hospital for surgical treatment, including 44 cases of laryngeal squamous cell carcinoma, 14 cases of hypopharyngeal squamous cell carcinoma, and 2 cases of nasal squamous cell carcinoma. pTNM staging according to AJCC 2010, Ⅲ stage 17 cases, Ⅳa stage 40 cases, and Ⅳb stage 3 cases; according to tumor differentiation degree: 13 cases of high differentiation, moderately differentiation in 31 cases, and 16 cases of low differentiated; primary tumor, positive lymph node metastasis as the experimental group, and 10 cases of adjacent tissues are taken as control (control group). The expression of EGFRvⅢ and CXCR4 in primary tumor, metastasis and control group was observed by immunohistochemistry. The immunohistochemical results are semi quantitatively analyzed by Image-Pro Plus. All analyses were conducted using the SPSS 23.0 and Graphpad-Prism 5.0. Result:The expression of EGFRvⅢ and CXCR4 in HNSCC is higher than control, which was not correlated with age, gender, location, degree of differentiation, T grading, and TNM stage (P>0.05). But there was a significant correlation with N grading (P<0.05). The pathology result shows lymph node metastasis in cancer tissues were high expression, but the difference in expression between primary and metastatic tumors are not statistically significant. There is no significant positive correlation between EGFRvⅢ and CXCR4 (r=0.144, P>0.05). Conclusion: Both EGFRvⅢ and CXCR4 promote the invasion and metastasis of advanced HNSCC, however, there may be some synergistic effect between them.

Abstract
Objective: To investigate the prevalence of metabolic syndrome (MS) among adults in rural areas of Ningxia Hui autonomous region. Methods: A cross-sectional study was conducted in 10 639 adults enrolled with a multistage method from Jingyuan County. The MS was identified according to Chinese type 2 diabetes prevention guide (2013). Results: Among all the subjects, 17.4% of them met the MS definition with the standardized prevalence of 14.7% after adjustment of sex and age. The prevalence and standardized rate of MS in men were 19.9% and 17.3%, and in women were 15.3% and 13.5%.The prevalence of MS in men was higher than that in women(P<0.001) and increased with aging in both genders. The prevalence and standardized rate of abdominal obesity, hyperglycemia, hypertension, high triglycerides, and low HDL-C were 19.5% and 16.7%, 15.0% and 12.9%, 42.0% and 37.1%, 25.8% and 23.1%, 28.5% and 27.7%, respectively. The rate of abdominal obesity was higher in women than in men (20.5% vs 18.2%, P=0.004), whereas the rate of hypertension, high triglycerides, and low HDL-C were higher in men than in women (all P<0.01). The prevalence of having one parameter of the MS was 68.4%. Conclusion: The prevalence of MS is higher in rural areas of Ningxia Hui autonomous region, suggesting that a series of comprehensive prevention measures should be carried out to prevent and control the MS so as to improve the public health conditions in rural areas.

Abstract
OBJECTIVES To explore the differences in the repair process of skin and skeletal muscle after contusion caused by blunt force attack with different heights. METHODS Three degrees of contusion were performed on SD rats' right hind limbs by a designed free-dropping device falling from 15, 30 and 50 cm heights, which as a main consideration factor for degree of injury. The repair process of skin and skeletal muscle at 6 h, 24 h, 3 d, 7 d and 13 d after contusion were observed using routine histological methods. RESULTS Hematoma within skin and/or muscle was found in the rats' hind limbs after contusion with three different heights. The repair processes were similar at 24 h after contusion. However, with the increase of height, the display degree was more obvious. At 3 d after contusion, the RBC of the hemorrhagic region would be decomposed and elapsed in 15 cm contusion group, but for 30 cm contusion group, it delayed to 7 d. At 13 d after contusion, the similar result was found in 15 cm and 30 cm contusion groups, in contrast, the 50 cm contusion group was still in the proliferative phase. CONCLUSIONS With the increase of height, the occurring rate of hematoma within skin and muscle at the same time increases, and the more serious histological appearance after contusion, including inflammation and proliferation, the longer healing process are observed. According to the results of present study and considering forensic application, the contusion model with 50 cm height (2.58 J/cm²) is recommended as the experimental animal model for the future study of wound age estimation on contusion.

Abstract
Objective:To introduce and discuss a surgical technique, i.e. lateral and posterior semicircular canal plugging with endolymphatic sac decompression, to treat intractable Meniere's disease.Method:Thirty-three cases of intractable Meniere's disease were enrolled. All cases were performed under general anesthesia. The endolymphatic sac was decompressed and the bone of lateral and posterior canal were drilled to create a fenestra followed by soft tissue plugging into the canal.Result:All cases had no facial palsy, no total defness, no vertical after surgery. In the period of following up, the attack of Meniere's disease was completely controlled and the hearing loss happened for 6 case one week after operation. One case had sudden hearing loss with vertical and result of defness.Conclusion:The design of this surgical procedure was based on relieving endolymphatic press and controlling the nerve pulse transmission. The surgical technique was reliable for lateral and posterior semicircular canal plugging with endolymphatic sac decompression.

Abstract
The side effects or toxicity of cyanoacrylate used in vivo have been argued since its first application in wound closure. We propose an airflow-assisted in situ precision electrospinning apparatus as an applicator and make a detailed comparison with traditional spraying via in vitro and in vivo experiments. This novel method can not only improve operational performance and safety by precisely depositing cyanoacrylate fibers onto a wound, but significantly reduce the dosage of cyanoacrylate by almost 80%. A white blood cell count, liver function test and histological analysis prove that the in situ precision electrospinning applicator produces a better postoperative outcome, e.g., minor hepatocyte injury, moderate inflammation and the significant ability for liver regeneration. This in situ precision electrospinning method may thus dramatically broaden both civilian and military applications of cyanoacrylates.
