[Research progress on pneumoconiosis markers based on multi-omics analysis].

The etiology of pneumoconiosis is relatively clear, but the pathogenic mechanism is not fully understood, and there is no effective cure for pneumoconiosis. Clarifying the pathogenesis of pneumoconiosis and exploring relevant markers can help screen high-risk groups of dust exposure, and relevant markers can also be used as targets to intervene in the process of pulmonary fibrosis. The in-depth development of genomics, transcriptomics and proteomics has provided a new way to discover more potential markers of pneumoconiosis. In the future, the combination of multi-omics and multi-stage interactive analysis can systematically and comprehensively identify key genes (proteins) , metabolites and metabolic pathways in the occurrence and development of pneumoconiosis, build a core regulatory network, and then screen out sensitive markers related to early diagnosis and treatment of pneumoconiosis. This article summarizes the research progress of pneumoconiosis markers from the perspective of multi-omics, hoping to provide more basic data for the early prevention and diagnosis of pneumoconiosis, pathogenesis research, and therapeutic intervention.

A comprehensive prognostic analysis of cause-specific mortality in patients with ovarian serous cystadenocarcinoma using a competing-risks model: a case study of the SEER database.

OBJECTIVE: This retrospective study employed a competing-risks analysis utilizing the Surveillance, Epidemiology, and End Results (SEER) database to identify precise prognostic factors associated with ovarian serous cystadenocarcinoma (OSCC) in patients. PATIENTS AND METHODS: Patients with OSCC during 2004-2015 were identified in the SEER database, and their clinicopathological, demographic, and survival data were examined. Univariate analysis using Gray's test and the cumulative incidence function was used to evaluate the prognoses of events of interest. The multivariate analysis involved several models, including the Cox proportional hazards, Fine-Gray, and cause-specific (CS) hazard function models, to estimate the hazard functions of competing risks. Hazard ratios were analyzed to identify the reliability of the prognostic factors. RESULTS: Among the 10,400 individuals diagnosed with OSCC, 5,713 died from the illness, and 1,125 died from other causes. The cumulative incidence rate of events of interest was found to be significant for ethnicity, age at diagnosis, histological grade, American Joint Committee on Cancer (AJCC) stage, chemotherapy and surgery status, tumor size, marital status, and local lymph node metastases (p<0.05). The multivariate analysis revealed that ethnicity, histological grade, surgery and chemotherapy status, age at diagnosis, AJCC stage, marital status, and distant metastases were independent prognostic factors in the Cox model (p<0.05). Finally, the Fine-Gray and CS models demonstrated that ethnicity, histological grade, surgery and chemotherapy status, age at diagnosis, AJCC stage, tumor size, marital status, and combination summary stage were all identified as independent prognostic factors (p<0.05). CONCLUSIONS: This study determined the risk factors for OSCC using a competing risk analysis model established by the SEER database. The findings can help clinicians understand OSCC better and provide more accurate medical support to affected patients.

[Dilemma and breakthrough in the advancement of bariatric and metabolic surgery in China].

China currently has the largest population of overweight and obese individuals globally. Bariatric surgery is by far the most effective approach to address obesity and associated metabolic conditions. To manage the significant growth of obesity, China's bariatric and metabolic surgery has assumed a pivotal role. Despite a delayed start compared to other nations, China has made significant progress in bariatric metabolic surgery over the past two decades. Presently, the annual number of surgeries ranks ahead worldwide. However, the proportion of eligible obese patients undergoing bariatric surgery in China remains lower than global averages. Looking ahead, China's bariatric metabolic surgery field offers ample room for growth and improvement. This paper aims to highlight the achievements in bariatric and metabolic surgery within China while also addressing challenges, such as the high proportion of laparoscopic sleeve gastrectomy, adherence to operation standards and guidelines, postoperative management and loss of follow-up, and quality control of database. By analyzing the current landscape and challenges, it is anticipated that China's bariatric metabolic surgery will continue to make remarkable progress in the future, bolstered by the collective dedication of the medical community.

[Efficacy analysis of laparoscopic sleeve gastrectomy in morbidly obese patients aged 10-21 years].

Objective: To investigate the efficacy of laparoscopic sleeve gastrectomy (LSG) in morbidly obese patients aged 10 to 21 years. Methods: We conducted a retrospective analysis of clinical data from 89 out of 200 patients who underwent LSG at the Gastrointestinal Surgery/Weight Loss Center of the First Affiliated Hospital of Jinan University between January 2015 and December 2020. The primary outcome measures were the completion rate of LSG, the incidence of perioperative complications, and weight-related indicators 3, 6, 12, and ≥24 months postoperatively. Additionally, we compared glucose metabolism, lipid metabolism, vitamin levels, liver function, and other relevant biochemical variables before and after surgery. Normally distributed continuous data are presented as x±s. Because the numbers of patients at each follow-up time point were not identical with the number of patients in the study cohort preoperatively, independent sample t-tests were used for intergroup comparisons. Non-normally distributed continuous data are presented as M(Q1, Q3), and Mann-Whitney U tests were used for intergroup comparisons. Results: Among the 89 patients, 35 were male (39.3%), the mean age was (18±2) years, and mean body mass index (BMI) 38.5±4.8 kg/m²; 37 of the patients having a BMI greater than 40 kg/m². Additionally, 63 patients (70.8%) had fatty livers, 34 (38.2%) hyperuricemia, 31(34.8%) sleep apnea syndrome, 20 (22.4%) gastroesophageal reflux, eight (8.9%) type 2 diabetes, and two (2.2%) hypertension. All 89 patients underwent LSG surgery successfully, with no conversions to open surgery. During the perioperative period, there were no cases of major bleeding, gastric leakage, or infections. Notable postoperative symptoms included nausea, vomiting, and pain, most of which improved by the second postoperative day. BMI values 3, 6, and 12 months postoperatively had decreased to 31.5±5.8 kg/m², 28.6±4.3 kg/m², and 26.3±4.4 kg/m², respectively. All of these BMI values differed significantly from preoperative values (all P<0.05). At 12 and ≥24 months postoperatively, the percentages of total weight loss were (31.3±9.3)% and (33.1±10.5)%, respectively, both differing significantly from 3 months postoperatively (20.5±5.1)% (all P<0.05). The percentages of excess weight loss at 12 and ≥24 months postoperatively were 91% (70%, 113%) and 95% (74%, 118%) , respectively, both differing significantly from the percentage of total weight loss 3 months postoperatively (56% [45%, 72%]) (both P<0.05). Alanine transaminase and aspartate transaminase serum concentrations decreased from preoperative values of 44.4 (25.5, 100.5) U/L and 29.0 (9.5, 48.0) U/L to 14.0 (10.8, 18.3) U/L and 13.0 (10.5, 17.3) U/L, respectively, ≥24 months postoperatively. Hemoglobin A1c decreased from 5.6 (5.3, 5.8)% preoperatively to ≥24 months postoperatively 5.3 (5.0, 5.4)%. High-density lipoprotein increased from 1.0 (0.9, 1.2) mmol/L preoperatively to 1.4 (1.1, 1.6) mmol/L ≥24 months postoperatively. Vitamin B12 decreased from 350.0 (256.8, 441.3) µg/L preoperative to 230.3(195.4, 263.9) µg/L ≥24 months postoperatively. All differed significantly from preoperative values (all P<0.05). Conclusion: LSG has favorable efficacy in morbidly obese patients aged 10 to 21 years. However, further confirmation is required through long-term, multicenter, randomized, controlled trials.

[Advances in endoscopic sleeve gastroplasty for the treatment of obesity and metabolic disease].

Obesity poses a serious threat to human health, and although bariatric surgery has been proven effective treatment for morbidly obese patients, its surgical risks and high medical costs limit its clinical application and popularity. Endoscopic sleeve gastroplasty (ESG), as a relatively new endoscopic surgery technique for weight loss, has satisfactory weight loss effects compared to laparoscopic sleeve gastrectomy and lifestyle interventions, while preserving the normal structure of the stomach. Its weight loss effects and safety have been validated in multicenter studies abroad. Although, ESG has not yet been widely performed in China, with the gradual maturity of this technique, its prospects are worth attention in the field of weight loss. In the future, large-scale, long-term, multi-center studies are urgently needed in China to clarify the long-term effects, remission of comorbidities, and occurrence of complications of ESG surgery in obese and metabolic disease patients.

[Progress in research of deaths and disease burden of major chronic diseases caused by indoor and outdoor air pollution in China].

Health damage including chronic disease caused by air pollution have attracted increasing attention. With the acceleration of industrialization and urbanization, the emission of air pollutants has increased, and its association with chronic diseases has become a research trending topic. Cardiovascular disease, cancer, diabetes, and chronic respiratory disease are the major chronic diseases, causing about 86.6% of the total deaths in China. The prevention and control of chronic diseases, especially the etiologic prevention, is a major public health issue related to national health. This article summarizes the recent progress in research of association of indoor and outdoor air pollution with all-cause mortality, the deaths and disease burden of four major chronic diseases, i.e. cardiovascular disease, cancer, diabetes, and chronic respiratory disease, and puts forward suggestions for the reduction of the burden caused by chronic diseases due to air pollution to provide a theoretical foundation to revise air quality standards in China.

[Progress in research of relationship between metal or metalloid and persistent organic pollutants exposures and cardiovascular disease].

Cardiovascular disease (CVD) is the leading cause of mortality and healthy life expectancy loss, ranking first in causing the global burden of disease. In addition to the traditional CVD risk factors, such as hypertension and diabetes, environmental chemical pollutants may also play a role in the development of CVD. This paper summarizes the evidence regarding the relation of exposures to metal or metalloid and persistent organic pollutants with risk for CVD and introduces the research progress in the relation between the exposures to two environmental chemical pollutants and CVD risk. The study aims to provide scientific evidence for the effective prevention of CVD through the management of chemical pollutants in environment.

[Application of transbronchial cryobiopsy in the diagnosis of postoperative complications after lung transplantation: a report of 6 cases].

Objective: To investigate the efficacy and safety of transbronchial cryobiopsy (TBCB) after lung transplantation. Methods: The clinical characteristics, TBCB procedure, diagnosis and treatment, and outcomes of lung transplant recipients of 6 patients (all male, aged 33-67 years) with TBCB in China-Japan Friendship Hospital from May to November 2021 were retrospectively analyzed. Results: Among the 6 patients diagnosed by TBCB, there were 2 cases of organizing pneumonia, 1 acute cellular rejection, 1 antibody-mediated rejection, and 1 bronchiolitis obliterans, and 1 diffuse alveolar damage. After the clinical diagnosis was confirmed, the condition improved after adjustment of the treatments followed. There were no serious complications related to the TBCB procedure. Conclusion: TBCB is valuable and relatively safe in the diagnosis of complications after lung transplantation, but the indications need to be strictly controlled.

Technological advances in the production of carotenoids and their applications- A critical review.

Carotenoids are naturally occurring pigments that are widely distributed in algae, fungi, bacteria, and plants. Carotenoids play a significant role in the food, feed, cosmetic, nutraceutical, and pharmaceutical industries. These pigments are effectively considered as a health-promoting compounds, which are widely used in our daily diet to reduce the risk of chronic diseases such as cardiovascular diseases, cancer, acute lung injury, cataracts, neural disorders, etc. In this context, this review paper demonstrates the synthesis of carotenoids and their potential application in the food and pharmaceutical industries. However, the demand for carotenoid production is increasing overtime, and the extraction and production are expensive and technically challenging. The recent developments in carotenoid biosynthesis, and key challenges, bottlenecks, and future perspectives were also discussed to enhance the circular bioeconomy.

Orquialgia aguda aislada como síntoma inicial del trastorno de la médula torácica: informe de 2 casos y revisión de la literatura / Acute isolated orchalgia as the initial symptom in thoracic cord disorder: 2 case report and literature review

Introducción: La orquialgia es un trastorno andrológico frecuente y suele darse como resultado de un cambio patognomónico en los testículos y las estructuras adyacentes. Sin embargo, su causa sigue siendo desconocida en más de una cuarta parte de los pacientes.MétodosInformamos de 2varones que presentaron inicialmente una orquialgia aguda y aislada, que se complicó conduciendo posteriormente a una paraparesia. Los 2tenían antecedentes de cáncer de próstata y mielitis cervical. El examen urológico fue negativo en ambos. Finalmente, se identificó metástasis del cáncer de próstata y mielitis recurrente a nivel de T2 y T3, respectivamente. Aunque la orquialgia cedió progresivamente, las disfunciones urológicas, sexuales y neurológicas persistieron en los 2pacientes.ConclusionesSegún la literatura existente, la enfermedad responsable de la orquialgia espinal se hallaba exclusivamente por debajo del nivel T10, lo que solía demorar el diagnóstico confirmatorio. Por lo tanto, en el caso de la orquialgia idiopática con una historia preexistente o riesgo de trastorno de la médula espinal y un estudio urológico negativo, se debe recomendar la evaluación exhaustiva de la médula espinal por encima del nivel T10.

Introduction: Orchalgia is a common andrological disorder and usually results from pathognomonic change of testes and regional structures. However, responsible cause is still unknown in more than one-fourth of patients.MethodsWe report 2men who initially suffered an acute, isolated orchalgia and posteriorly complicated with paraparesis. They had previous history of prostate cancer and cervical myelitis. The urological examination was negative in both of them. Finally, prostate cancer metastasis and recurrent myelitis at T2/3 level was identified, respectively. Although their orchalgia progressively subsided, their urological, sexual and neurological dysfunction persisted.ConclusionsIn the literature, the responsible pathology of spinal orchalgia was exclusively found below T10 level, frequently delaying affirmative diagnosis. Therefore, a thorough evaluation of spinal cord above T10 level should be alerted for idiopathic orchalgia with a pre-existing history or risk of spinal cord disorder and a negative urological examination.

[Application of the concept of precision obesity metabolic surgery in laparoscopic Roux-en-Y gastric bypass].

Due to the complexity and heterogeneity of obesity, the diagnosis and treatment of obesity vary greatly. Five to 10 percent of body weight can be lost through lifestyle modifications, nutritional and behavioral counseling, and the use of approved weight reduction medicines for obesity and diabetes; however, these non-surgical treatments are not effective for all patients. Compared to medical therapy, bariatric surgery is associated with higher rates of type 2 diabetes remission, lower mortality from vascular complications, and long-term, sustained weight loss. With the advent of precision medicine in surgical therapy, bariatric surgeons' fundamental understanding of laparoscopic Roux-en-Y gastric bypass surgery has evolved in recent years. The objective of surgery has shifted from short-term weight loss to the safe and successful long-term management of patient weight and comorbidities. In laparoscopic Roux-en-Y gastric bypass surgery, the concept of precision bariatric and metabolic surgery is mainly reflected in three aspects: accurate preoperative assessment, precise intraoperative operation, and comprehensive postoperative management. A new direction for the future development of precision laparoscopic Roux-en-Y gastric bypass surgery and obesity metabolic surgery is to formulate precise and individualized surgical treatment plans for patients and to use artificial intelligence and big data technology to improve the standardization of specialist data.

[Three cases of hemodiafiltration for the treatment of CAR-T related grade 3 - 4 cytokine release syndrome after ineffective treatment with IL-6 receptor inhibitors].

Objective: To investigate the efficacy and safety of hemodiafiltration (HDF) in treating CAR-T related grade 3-4 cytokine release syndrome after ineffective treatment with IL-6 receptor inhibitors. Methods: Between July 2015 and July 2021, retrospective analysis of hemodiafiltration for the treatment of 3 patients, including 2 cases of acute B-lymphoblastic leukemia and 1 case of diffuse large B-cell lymphoma, with grade 3-4 CRS after CAR-T cell therapy and ineffective treatment with IL-6 receptor inhibitor was carried out. Results: The patient's clinical symptoms, including body temperature, blood pressure, and blood oxygen, were relieved within 12 hours of all treatments, and the cytokines (IL-6, IL-10, TNF-α, INF-γ) and C-reactive protein (CRP) levels decreased significantly. No adverse side effects were observed during the follow-up period of 3 months. Conclusion: HDF can be a safe and feasible method to treat CAR-T related grade 3- 4 CRS after ineffective treatment with IL-6 receptor inhibitors.

[Progress in the epidemiological studies on coal mine dust exposure with workers' health damage].

Coal is one of the major fuels, which brings huge energy and economic benefits to global industry and daily life. large amounts of coal dust produced in the process of coal mining and transportation, which seriously threatens the health of related workers. Productive coal dust exposure not only directly leads to respiratory diseases, but also may cause health damage to various systems throughout the body. Numerous studies have shown that coal dust exposure is closely associated with decreased lung function, coal worker's pneumoconiosis, chronic obstructive pulmonary disease, lung cancer, and cardiovascular diseases, and the severity of diseases is affected by coal rank, coal dust concentration, cumulative dust exposure, coal dust composition, and individual lifestyle, etc. The article comprehensively summarized the progress of the epidemiological studies on the health hazards of coal miners from coal dust exposure, in order to provide clues for further researches on health damage and protect the health of the occupational population.

[Pneumatosis cystoides intestinalis in lung transplant recipients: three cases report and literature review].

Objective: To report the clinical characteristics and treatment courses of pneumatosis cystoides intestinalis(PCI) after lung transplantation(LT). Methods: We included all cases of PCI after LT from March 2017 to June 2021 in China-Japan Friendship Hospital. In addition to our cases, we searched literatures published in Chinese and English languages using China National Knowledge Infrastructure (CNKI), Wanfang Data and PubMed/MEDLINE with the search terms"pneumatosis intestinalis"and"lung transplantation". The clinical characteristics and treatment courses of all cases were summarized and analyzed. Results: Three cases of PCI occurred after LT in this study, with an incidence of 0.804% (3/373). Thirteen related literatures were retrieved, with 51 cases enrolled. The median age of the 54 patients was 55.4 years (22-79 years), with 33 males and 21 females. 64.81% (35/54) of the 54 patients underwent LT for interstitial lung disease and 90.74% (49/54) underwent bilateral LT. Twenty-two cases(40.7%) were asymptomatic when PCI occurred. Thirty-eight cases (38/54,70.37%)had involvement of ascending colon, and 35 cases(35/54,64.81%)had involvement of transverse colon. Forty-three cases(43/54, 79.63%) were treated conservatively. The average interval between transplantation and PCI was 210 (5-2 495) days. Conclusion: PCI is a rare complication after lung transplantation, most often occurring in the colon. Most patients were asymptomatic and could improve by conservative treatments.

[Association between occupational noise exposure and the risk of cardiovascular diseases].

Objective: To explore the association between occupational noise exposure and cardiovascular disease (CVD) risk in a large Chinese population. Methods: In December 2019, the study included 21412 retired participants from the Dongfeng-Tongji Cohort Study at baseline from September 2008 to June 2010, occupational noise exposure was evaluated through workplace noise level and/or the job titles. In a subsample of 8931 subjects, bilateral hearing loss was defined as a pure-tone mean of 25 dB or higher at 0.5, 1 , 2, and 4 kHz in both ears. Logistic regression models were used to explore the association of occupational noise exposure, bilateral hearing loss with 10-year CVD risk. Results: Compared with participants without occupational noise exposure, the 10-year CVD risk was significantly higher for noise exposure duration ≥20 years (OR=1.20, 95%CI:1.01-1.41 , P=0.001) after adjusting for potential confounders. In the sex-specific analysis, the association was only statistically significant in males (OR=2.34, 95%CI: 1.18-4.66, P<0.001) , but not in females (OR=1.15, 95%CI:0.97-1.37, P=0.153). In the subsample analyses, bilateral hearing loss, which was an indicator for exposure to loud noise, was also associated with a higher risk of 10-year CVD (OR= 1.17, 95% CI:1.05-1.44, P <0.001) , especially for participants who were males (OR =1.24, 95% CI:1.07-2.30, P<0.001) , aged equal and over 60 years old (OR=2.30, 95%CI: 1.84-2.88, P<0.001) , and exposed to occupational noise (OR=1.66, 95%CI: 1.02-2.70, P=0.001). Conclusion: Occupational noise exposure may be a risk factor for CVD.

[Early onset Epstein-Barr virus-negative diffuse large B cell lymphoma after bilateral lung transplantation: a case report].

Lymphoma after solid organ transplantation is one of the manifestations of post-transplant lymphoproliferative disorders(PTLD). Here we reported a 39-year-old male patient presented with intermittent fever, markedly elevated level of peripheral blood lymphocytes and lactate dehydrogenase(LDH), rapid decrease in hemoglobin and platelet count ten months after bilateral lung transplantation. After systematic evaluation, the patient excluded infectious diseases. Positron emission tomography-computed tomography (PET/CT) revealed diffuse increasing of standard uptake value in bones throughout the body. The bone marrow aspiration, flow cytometric analysis and histopathology confirmed the diagnosis of diffuse large B-cell lymphoma (DLBCL) with negative Epstein-Barr virus-encoded small RNA (EBER) hybridization in situ. Meanwhile, complicated hemophagocytic lymphohistiocytosis was also diagnosed in the patient based on hypertriglyceridemia, abnormally elevated level of serum ferritin and solvable CD25 (sCD25). Treatment regimen included reduction of immunosuppression, anti-CD20 antibody (CD20+ B cell inhibitor, rituximab) and etoposide. Repeated PET/CT and bone marrow biopsy showed complete remission of lymphoma after 4 months of therapy.
