Chronic mucocutaneous candidiasis (CMC) is an infectious phenotype characterized by recurrent or persistent infections caused by Candida species that affect the skin, nails, oral, and genital mucosae for a duration exceeding six months. Current research suggests that CMC is an immunodeficiency disease with a complex pathogenesis. Patients with CMC have various defects in nonspecific and/or specific immunity against Candida infection, resulting in the inability of patients to defend themselves against Candida infection. CMC can be stratified into primary CMC and secondary CMC based on etiology. Primary CMC is often associated with genetic mutations leading to immunodeficiencies in T helper cell 17 and interleukin-17, whereas secondary CMC is frequently linked to factors such as human immunodeficiency virus infection, diabetes mellitus, and immunosuppressive therapy. Primary CMC typically manifests as Candida infections, with distinct genetic mutations often correlating to varied concomitant symptoms. Secondary CMC may present with not only superficial mucosal Candida infections and manifestations of the underlying primary disease but also with invasive fungal infections. Diagnosing CMC requires an integration of medical history and clinical presentation, supplemented by the outcomes of auxiliary diagnostic procedures, including microscopic examination of fungal smear, fungal culture, immunological testing, and genetic sequencing and analysis. Furthermore, confirming primary CMC requires exclusion of the aforementioned secondary factors. At present, antifungal drugs such as triazoles, echinocandins, and polyenes are the main treatment for CMC. Moreover, immunotherapy with biologics such as Janus kinase (JAK) inhibitors provides more options for the clinical treatment of patients with CMC. Gene therapy also has potential clinical application value. In this review, we discuss the etiologies, pathogenesis, clinical manifestations, diagnosis, and treatments of CMC, aiming to provide a reference for the clinical diagnosis and treatment of CMC.

Background Depressive symptoms have become a significant factor affecting the physical and mental health of the occupational population, and workers in petroleum refining enterprises face multiple stressors in their work environment. Objective To explore the impact of occupational noise exposure on depressive symptoms among workers in a petroleum refining enterprise. Methods This cross-sectional study was conducted in July 2024 using a questionnaire survey among workers of a petroleum refining enterprise in Hainan Province. Basic information of the subjects was collected. The Center for Epidemiologic Studies Depression Scale (CES-D) was used to measure depressive symptoms, the Chinese version of the Pittsburgh Sleep Quality Index (PSQI) scale was used to assess sleep quality, and the Chinese version of the Effort-Reward Imbalance (ERI) scale was used to evaluate occupational stress. Chi-square test was employed to compare the differences in reporting depressive symptoms among populations with different characteristics. Binary logistic regression models were used to analyze the impact of occupational noise exposure and other factors on depressive symptoms. Results The overall positive rate of depressive symptoms in the study population was 42.7%. The results of the multifactor analysis indicated that compared with the control group, employees in both the low-exposure and high-exposure groups had elevated odds of depressive symptoms, with OR (95%CI) of 2.244 (1.131, 4.454) and 1.970 (1.009, 3.850), respectively. This association remained robust after adjusting for potential confounders, including gender, age, work tenure, and other occupational exposures. Additionally, female [OR (95%CI)=1.483 (1.039, 2.118)], exposure to benzene, toluene, or xylene [OR (95%CI)=1.621 (1.208, 2.174)], sleep disturbance [OR (95%CI)=3.772 (2.942, 4.838)], and occupational stress [OR (95%CI)=2.018 (1.575, 2.585)] were also significantly associated with higher odds of depressive symptoms. Conclusion The positive rate of depressive symptoms is relatively high among employees in this petrochemical enterprise, and occupational noise exposure may be a risk factor for depressive symptoms.

Objective:To explore the regulation and mechanism of human placental extract(HPE)on lipopolysaccharide(LPS)-induced BV2 microglial cell inflammation.Methods:Microglia cell lines(BV2)were cultured in vitro and divided into PBS group,HPE group,LPS group and LPS+HPE group.BV2 cell viability was measured by CCK-8 analysis.A fluorescent probe targeting reactive oxygen species(ROS)was to detect the level of intracellular ROS.The mRNA levels of TNF-α,IL-1β and IL-6 were detected by RT-qPCR.The supernatants of different treatment groups were collected.The content of nitric oxide(NO)was detected by the Griess method,and the secretion levels of TNF-α,IL-1β and IL-6 were detected by the flow magnetic bead microarray(CBA)method.The indirect contact co-culture system between BV2 and mouse hippocampal neurons cell line HT22 cells was established to evaluate the neurotoxicity of HPE by the assessment of the cell viability and apoptosis of HT22 cells using CCK-8 or flow cytometry.The potential signaling molecules of NF-κB signaling pathway was detected by flow cytometry.Results:Compared with the PBS group,1.2 μg/ml LPS and 50 ng/ml HPE significantly inhibited the activity of BV2 cells.Compared with the PBS group,the mRNA levels of TNF-α,IL-1β and IL-6 in BV2 cells of the LPS group were significantly increased(P<0.05),and the secretion levels of NO,TNF-α,IL-1βand IL-6 in the supernatant were also significantly upregulated(P<0.05).The expressions of related signaling pathway molecules Toll-like receptor 4(TLR4),pIκBα and pNF-κB p65 were significantly increased(P<0.05).Compared with the LPS group,the mRNA levels of TNF-α,IL-1β and IL-6 in BV2 cells,the secretion levels of NO,TNF-α,IL-1β and IL-6,the neurotoxicity and neuronal apoptosis induced by microglial conditional medium,and the expressions of TLR4,pIκBα and pNF-κB p65 in the LPS+HPE group were significantly downregulate(P<0.05).Conclusion:HPE may alleviate the microglial inflammation,possibly through the TLR4/NF-κB signaling pathway.

Background and purpose:Thyroid cancer is the most common malignant endocrine tumor,particularly prevalent among the Asian population.The overall survival for thyroid cancer patients is relatively high,but there are significant survival differences among patients.Based on long-term hospital-based cancer registry database,this study analyzed the 10-year observed overall survival(OS)rate of thyroid cancer cases and the distribution of causes of death,providing real-world evidences to further survival management of thyroid cancer in China.Methods:A total of 55343 thyroid cancer patients who underwent treatment at Fudan University Shanghai Cancer center from 2005 to 2021 were included in this study.Clinical information and the follow-up endpoint data were collected through medical records review,telephone visits and death registry data linkage.The last follow-up date was October 31,2024.Kaplan-Meier method was applied in evaluating the OS rate,and survival data were described by different subgroups as age group,gender,treatment period,tumor staging and pathological characteristics.The standardized mortality ratio(SMR)and absolute excess risk(AER)were calculated using general Shanghai population as the reference,and the mortality risk was described by gender,age at diagnosis and histological subtype.Results:With a median follow-up time of 63.01 months,the overall 1-,3-,5-and 10-year OS rates of thyroid cancer patients were 99.67%(95%CI:99.62%-99.72%),99.11%(95%CI:99.03%-99.19%),98.48%(95%CI:98.36%-98.60%)and 95.81%(95%CI:95.50%-96.11%),respectively.The 10-year OS rates of stage Ⅰ,Ⅱ,Ⅲ and Ⅳ were 97.99%(95%CI:97.70%-98.28%),89.80%(95%CI:87.24%-92.37%),77.84%(95%CI:70.76%-84.92%)and 62.95%(95%CI:55.37%-70.54%),respectively.The differences in OS among patients with different age,gender and histological classification were significant.1256(2.27%)deaths occurred,of which 18.63%,50.88%and 7.32%were attributable to thyroid cancer,other cancers and cardiovascular disease(CVD),respectively.Compared with the general population,patients with different subtypes of thyroid cancer had higher all-cause mortality rates,progressively increasing with papillary,follicular,medullary and anaplastic thyroid carcinoma/poorly differentiated carcinoma.Compared with general population,the death risk was 2.24 times higher in papillary thyroid cancer patients(95%CI:2.06-2.44),9.94 times higher in follicular thyroid cancer patients(95%CI:6.79-14.09),12.16 times higher in medullary thyroid cancer patients(95%CI:8.05-17.69),and the highest risk was observed in patients with anaplastic thyroid carcinoma/poorly differentiated carcinoma[SMR=79.67(95%CI:58.38-106.31),AER=766.01/1 000 person-years].Conclusion:The 10-year long survival data and cause of death for thyroid cancer patients with different histological types were reported in China based on a large single institution hospital-based cancer registry database.Staging and histological characteristics were the most important factors directly affected the survival.Early diagnosis and individualized treatment are crucial for improving prognosis.

Objective To explore the effects of different nerve blocks under ultrasound guidance on the expression of inflammatory factors after total hip replacement in the elderly,and its correlation with postoperative cognitive dysfunction(POCD).Methods A total of 100 elderly patients who underwent total hip replacement in our hospital from February to November 2023 were selected as the research objects,and they were divided into the femoral nerve block(FNB)group and the pericapsule nerve group block(PNGB)group according to different nerve block methods during the operation.The expression of inflammatory factors such as serum interleukin-1β(IL-1β),interleukin-6(IL-6),interleukin-10(IL-10),tumor necrosis factor-α(TNF-α)and tumor necrosis factor-β(TNF-β)1 day before surgery,6 hours after anesthesia,1 day after surgery,and 3 days after surgery of patients in the two groups were compared.The cognitive function of patients was evaluated by the mini-mental state examination(MMSE)score,and the pain of patients was evaluated by visual analogue scale(VAS)score.GEE model was used to evaluate the effects of two kinds of nerve block on the expression of inflammatory factors.Logistic regression was used to analyzed the correlation between postoperative inflammatory factors and POCD in patients.Results The levels of IL-1β,IL-6,IL-10,TNF-α and TNF-β 1 day after operation in the PNGB group were higher than those in the FNB group,and the differences were statistically significant(P<0.05).The MMSE score 1 day after surgery in the PNGB group was significantly higher than that in the FNB group(P<0.05),and the VAS score 3 days after surgery was significantly lower than that in the FNB group(P<0.05).GEE model showed that PNGB has a greater impact on IL-1β,IL-6,IL-10,TNF-α,and TNF-β.IL-1β,IL-6,IL-10,TNF-α,and TNF-β were all independently related to POCD induced by two different nerve blocks(P<0.05).Conclusion PNGB can effectively inhibit pro-inflammatory factors,reduce inflammatory stress responses,and maintain the balance of inflammatory factors.Inflammatory factors are independently related to POCD induced by different nerve blocks.With the occurrence of inflammatory stress response,the risk of POCD in patients increases.

Streptococcus equinus is a zoonotic disease that can cause illness in various animals under specific environmental condi-tions.No reports have described isolation of this bacterium from the liver in affected sheep.This study successfully isolated and identi-fied a strain of Streptococcus equinus through bacterial isolation and culture,Gram staining,drug sensitivity testing,mouse sensitivity testing,bacterial biochemical testing,and whole genome sequencing.The strain was found to have pathogenicity toward Kunming white mice,and to be sensitive to four antibiotics(penicillin,ampicillin,ceftiofur sodium,and ceftriaxone sodium)but resistant to four antibiotics(streptomycin,amoxicillin,tetracycline,and gentamicin).On the basis of drug sensitivity testing,targeted treatment of the affected sheep flock with ceftiofur sodium effectively controlled the disease within 2 days,and no new cases occurred.This study provides a reference for biological characterization of ovine Streptococcus equinus;public health;and the investigation of disease pre-vention,control,and epidemiology.
