Objective To identify long non-coding RNA (lncRNA) associated with rheumatoid arthritis-associated interstitial lung disease (RA-ILD) and investigate their mechanisms. Methods Peripheral blood samples were collected from RA-ILD patients (n=3), RA patients without lung involvement (n=3), and healthy controls (n=3). Next-generation sequencing was performed to screen differentially expressed lncRNA. A human fibrotic lung cell model was established by inducing the MRC-5 cell line with transforming growth factor-β (TGF-β). Following siRNA-mediated knockdown of target genes, changes in inflammatory and oxidative stress-related genes were analyzed via real-time quantitative reverse transcription polymerase chain reaction (qRT-PCR). Western blotting and dual-luciferase reporter (DLR) assays were used to validate protein expression, ubiquitination levels, and nuclear translocation of oxidative stress regulators, and antioxidant response element (ARE) transcriptional activity. Rescue experiments were conducted to confirm the role of target lncRNA in oxidative stress and inflammation in fibrotic lung cells. Results High-throughput sequencing revealed significant downregulation of LINC00638 in RA-ILD patients. Knockdown of LINC00638 markedly reduced transcriptional levels of interleukin (IL)-4, nuclear factor erythroid-2-related factor 2 (Nrf2), heme oxygenase-1 (HO-1), and superoxide dismutase 2 (SOD2), while increasing IL-6, IL-1β, interferon-γ (IFN-γ), and reactive oxygen species (ROS) levels. Furthermore, LINC00638 knockdown decreased Nrf2 protein expression, increased its ubiquitination, reduced nuclear translocation, and suppressed ARE transcriptional activity. In MRC-5 cells, LINC00638 knockdown combined with N-acetylcysteine treatment restored Nrf2 and HO-1 levels while reducing IL-6 expression. Conclusions LINC00638 suppresses inflammatory responses in RA-ILD by activating the Nrf2/ARE antioxidant signaling pathway, suggesting its potential as a therapeutic target for diagnosis and treatment.

ObjectiveTo assess the level of internal exposure to PCP in a community population in Shanghai, to investigate the factors affecting the level of PCP, and to analyze the correlation between the exposure and thyroid hormone levels. MethodsA total of 464 residents of a community in Shanghai were selected as the study subjects. A questionnaire survey was conducted to obtain the demographic information, dietary situation, lifestyle and behavioral habits, and disease history of the individuals, and blood samples were collected. Gas chromatography-electron trap was applied to determine the PCP levels in serum. Multicategorical logistic regression analysis was used to analyze the possible influencing factors of PCP exposure in humans. Thyroid hormone levels were used as the dependent variable and serum PCP as the independent variable. Multiple linear regression analysis was used to assess the association between PCP and thyroid hormones in the community population after controlling the confounding factors such as age, gender, literacy, annual personal income, and chronic diseases. ResultsThe detection rate of serum PCP in 464 subjects was 90.3%, and the median serum PCP level was 0.43 μg·L-1. The differences in PCP levels among different age groups were statistically significant. There were no significant differences in PCP levels among different gender and BMI groups. The study of PCP exposure factors showed that age, frequency of using plastic products, consumption of freshwater fish, type of occupation, annual income, and consumption of tea or coffee were the potential influencing factors for PCP exposure. Among them, age, frequency of using plastic products, consumption of tea or coffee, and consumption of freshwater fish were positively associated with PCP levels, and annual personal income was negatively associated with it. The results of multiple linear regression analysis showed that among men, PCP levels were positively correlated with TSH (b=0.105, 95%CI:0.017‒0.313) and negatively correlated with FT4 (b=-0.026, 95%CI:-0.057‒0.004), and among women, PCP levels were positively correlated with TSH (b=0.092, 95%CI:-0.211‒0.904) and FT3 (b=0.017, 95%CI:-0.058‒0.230) and negatively correlated with FT4 (b=-0.013, 95%CI:-0.011‒0.037). ConclusionSerum PCP detection is common among community residents in Shanghai. Different demographic characteristics or behavioral habits may increase or decrease PCP exposure. PCP exposure then affects human thyroid hormone levels.

ObjectiveTo understand the death status of major chronic diseases among the registered residents in Xuhui District, Shanghai from 2007 to 2021, and to analyze the probability and trend of premature death, so as to provide an evidence for the policy-making of disease control and prevention. MethodsBased on the data from the death registration system of the registered residents in Xuhui District, Shanghai from 2007 to 2021, the mortality rate of major chronic diseases, life expectancy without cause of death, potential years of life lost (PYLL), average years of life lost (AYLL), and premature death rate were calculated. Joinpoint 4.8 software was used to calculate the annual percentage change (APC) of premature death rate and its trend. ResultsIn 2021, the mortality rate and standardized mortality rate of four major chronic diseases, namely cardiovascular and cerebrovascular diseases, malignant tumors, diabetes mellitus and chronic lower respiratory diseases among the registered residents in Xuhui District, Shanghai was 767.75/100 000 and 234.69/100 000, respectively, accounting for 85.63% of the total causes of death among the residents in Xuhui District, Shanghai. The PYLL, AYLL and PYLL rate were 10 710.00 person-years, 1.49 years per person, and 11.43‰, respectively. Life expectancy increased by 14.91 years after removing the four major chronic diseases. From 2007 to 2021, the premature death rate of chronic diseases among the registered residents in Xuhui District decreased from 9.38% to 7.91% (APC=-1.09%,P<0.05). Malignant tumors had the highest rate in premature death, and the premature death rate was higher in males than that in females, with a slower rate of decline than in females. Cardiovascular and cerebrovascular diseases, malignant tumors and chronic lower respiratory diseases showed a significant decreasing trend in premature death rate (APC=-1.30%, -1.20%, -5.42%, P<0.05), while diabetes mellitus showed a significant increasing trend in premature death rate (APC=3.20%, P<0.05). There was a significant increasing trend in the rate of premature death from diabetes mellitus in males (APC=5.15%, P<0.05) and a decreasing trend in the rate of premature death from diabetes mellitus in females (APC=-0.76%, P<0.05). ConclusionCardiovascular and cerebrovascular diseases, malignant tumors, diabetes mellitus and chronic lower respiratory diseases are the main causes of death among the registered residents in Xuhui District. The probability of premature death of the residents in Xuhui District from major chronic diseases is at a low level, indicating that the prevention and control of chronic diseases in Xuhui District has achieved some success, but it is still difficult to realize the goals of the Outline of the "Healthy China 2030" Plan. Therefore, it is necessary to comprehensively carry out the control of risk factors such as tobacco use, harmful alcohol consumption, salt intake, hypertension, hyperglycemia and obesity, especially to strengthen the control of risk factors for male residents, as well as early diagnosis and treatment of malignant tumors, cardiovascular and cerebral vascular diseases and diabetes mellitus, and to implement the disease management mechanism to reduce premature death.

Allogeneic hematopoietic stem cell transplantation is an effective method for treating various hematological diseases. Membranous nephropathy is the second leading cause of novo glomerular disease after transplantation. Protocadherin FAT1 is a target antigen for diagnosing membranous nephropathy, primarily related to hematopoietic stem cell transplantation. Here we report a rare case of membranous nephropathy after hematopoietic stem cell transplantation. The target antigen of membranous nephropathy was confirmed to be FAT1 by pathology combined with mass spectrometry analysis. The nephrotic syndrome achieved partial remission after corticosteroid combined with cyclosporine treatment, and the patient's condition was stable during follow-up.

ObjectiveTo compare the incidence of respiratory and allergic diseases in children in Xuhui District, Shanghai in 2013 and 2020, and to determine the influencing factors. MethodsAnnual average levels of air pollutants including PM2.5, PM10, O3, SO2, and NO2 were collected and described in Shanghai from 2013 to 2020. A cross-sectional survey was conducted by using a questionnaire among grade 3 to 5 students in a school in Xuhui District, Shanghai, in September 2013 and 2020, respectively. The questionnaire collected variables including living environment, daily habits, family history of respiratory and allergic diseases, and incidence of these diseases in children. Chi-square test was used to determine the difference across respiratory and allergic diseases. Logistic regression was conducted to determine the influencing factors. ResultsA total of 1 398 valid questionnaires were collected (705 in 2013 and 693 in 2020). Compared with 2013, annual average concentrations of PM2.5, PM10, O3, SO2, and NO2 in 2020 significantly decreased. The prevalence of bronchial asthma, bronchitis, persistent cough and persistent expectoration in 2013 were significantly higher than those in 2020 (P<0.05) in Xuhui District. Multivariate analysis showed that severe air pollution, boys, parents with asthma or allergy, parents with higher educational levels, and more allergens in household were the risk factors associated with the incidence of bronchial asthma, bronchitis, allergic rhinitis and atopic eczema (P<0.05). Parents with allergy history, high smoking frequency of family member, and more allergens in household were the risk factors associated with the incidence of persistent cough and persistent expectoration (P<0.05). ConclusionTo 2013,2020 air pollution in Shanghai has been mitigated and prevalence of bronchial asthma and bronchitis of children has decreased. Childhood respiratory and allergic diseases are associated with indoor and outdoor environment, family medical history, and family daily habits.

BACKGROUND:
LY01005 (Goserelin acetate sustained-release microsphere injection) is a modified gonadotropin-releasing hormone (GnRH) agonist injected monthly. This phase III trial study aimed to evaluated the efficacy and safety of LY01005 in Chinese patients with prostate cancer.
METHODS:
We conducted a randomized controlled, open-label, non-inferiority trial across 49 sites in China. This study included 290 patients with prostate cancer who received either LY01005 or goserelin implants every 28 days for three injections. The primary efficacy endpoints were the percentage of patients with testosterone suppression ≤50 ng/dL at day 29 and the cumulative probability of testosterone ≤50 ng/dL from day 29 to 85. Non-inferiority was prespecified at a margin of -10%. Secondary endpoints included significant castration (≤20 ng/dL), testosterone surge within 72 h following repeated dosing, and changes in luteinizing hormone, follicle-stimulating hormone, and prostate specific antigen levels.
RESULTS:
On day 29, in the LY01005 and goserelin implant groups, testosterone concentrations fell below medical-castration levels in 99.3% (142/143) and 100% (140/140) of patients, respectively, with a difference of -0.7% (95% confidence interval [CI], -3.9% to 2.0%) between the two groups. The cumulative probabilities of maintaining castration from days 29 to 85 were 99.3% and 97.8%, respectively, with a between-group difference of 1.5% (95% CI, -1.3% to 4.4%). Both results met the criterion for non-inferiority. Secondary endpoints were similar between groups. Both treatments were well-tolerated. LY01005 was associated with fewer injection-site reactions than the goserelin implant (0% vs . 1.4% [2/145]).
CONCLUSION:
LY01005 is as effective as goserelin implants in reducing testosterone to castration levels, with a similar safety profile.

The acute combination fractures of the atlas and axis in adults have a higher rate of neurological injury and early death compared with atlas or axial fractures alone. Currently, the diagnosis and treatment choices of acute combination fractures of the atlas and axis in adults are controversial because of the lack of standards for implementation. Non-operative treatments have a high incidence of bone nonunion and complications, while surgeries may easily lead to the injury of the vertebral artery, spinal cord and nerve root. At present, there are no evidence-based Chinese guidelines for the diagnosis and treatment of acute combination fractures of the atlas and axis in adults. To provide orthopedic surgeons with the most up-to-date and effective information in treating acute combination fractures of the atlas and axis in adults, the Spinal Trauma Group of Orthopedic Branch of Chinese Medical Doctor Association organized experts in the field of spinal trauma to develop the Evidence-based guideline for clinical diagnosis and treatment of acute combination fractures of the atlas and axis in adults ( version 2023) by referring to the "Management of acute combination fractures of the atlas and axis in adults" published by American Association of Neurological Surgeons (AANS)/Congress of Neurological Surgeons (CNS) in 2013 and the relevant Chinese and English literatures. Ten recommendations were made concerning the radiological diagnosis, stability judgment, treatment rules, treatment options and complications based on medical evidence, aiming to provide a reference for the diagnosis and treatment of acute combination fractures of the atlas and axis in adults.

Objective:To investigate the efficacy and related influencing factors of autologous hematopoietic stem cell transplantation(auto-HSCT)as first-line consolidation therapy for newly diagnosed elderly patients with diffuse large B cell lymphoma(DLBCL).Methods:Retrospective study of clinical characteristics, therapeutic effect, and prognostic factors of newly diagnosed DLBCL elderly patients with an International Prognostic Index(IPI)score≥3 who underwent auto-HSCT in the Affiliated People's Hospital of Ningbo University from January 2015 to August 2020.Results:Among the 31 patients, 18 were males and 13 were females, with a median age of 65(60-75)years.The 13 cases(41.9%)were involved in 2 sites outside lymph nodes, and 13 cases(41.9%)were involved in bone marrow.IPI medium and high risk(IPI=3 points)was found in 21 cases(67.7%), high risk(≥4 points)in 10 cases(32.2%). Before transplantation, 21(67.7%)patients achieved complete remission(CR), and the other 10(32.3%)patients were in the partial remission(PR). All patients after transplantation achieved hematopoietic reconstitution.The median time for neutrophil and platelet engraftment were 10(9-16)days and 12(8-58)days respectively.During a median follow-up of 20.9(3.1 to 73.0)months after transplantation, transplant-related mortality within 100 days was 3.2%(1/31). The 2-year overall survival(OS)and progression-free survival(PFS)were(77.2±8.4)% and(72.7±8.3)%, respectively.Multivariate Cox analysis showed that the achieved partial remission status before auto-hematopoietic stem cell transplantation[OS( HR=30.064, 95% CI: 2.231-405.209, P=0.010), PFS( HR=9.165, 95% CI: 1.926-43.606, P=0.005)], and CD34 + cell count in graft <3×10 6/kg[OS( HR=12.004, 95% CI: 1.234-116.807, P=0.032), PFS( HR=6.115, 95% CI: 1.325-28.221, P=0.020)]were the independent poor prognostic factor affecting both OS and PFS in elderly lymphoma patients. Conclusions:Auto-HSCT may improve the survival rate of carefully selected elderly patients with DLBCL.Pretransplant disease status and the number of CD34 + cells in the graft are important factors to predict the efficiency of auto-HSCT of the patients.

Biliary malignant tumors have an insidious onset and rapid development, and most patients have lost the opportunity for radical surgery at initial diagnosis and often have poor prognosis. Gemcitabine-based chemotherapy is the first-line treatment for biliary malignant tumors, but with a limited clinical effect. The improvement in next-generation sequencing technology provides the possibility for the precise treatment of biliary malignant tumors, but the application and development of the precise treatment of biliary malignant tumors are limited by the low positive rate of targets and the poor accessibility of therapeutic drugs. The advent of the era of immunotherapy represented by the immune checkpoint inhibitor PD1/PD-L1 monoclonal antibody brings a promising future for the treatment of malignant tumors, including biliary malignant tumors. Combined chemotherapy and/or targeted therapy based on immune checkpoint inhibitors has shown a good effect in the treatment of biliary malignant tumors, which is the direction of the treatment of advanced biliary malignant tumors in the future.
