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.

Objective:To investigate the clinicopathological features and differential diagnosis of male genital system lympho-ma(MGSL).Methods:We retrospectively analyzed the clinicopathological and immunophenotypic features and prognosis of 80 ca-ses of MGSL.Results:The onset age of the MGSL patients ranged from 4 to 85(median 62)years old.All the cases showed non-specificity of the imaging features and clinical manifestations.MGSL was located mainly in the testis(n=66),followed by the pros-tate(n=7),epididymis(n=3),scrotum(n=3)and penile glans(n=1).Diffused large B cell lymphoma(DLBCL)was the most common pathological type(n=62),next came extranodal marginal zone lymphoma of mucosa-associated lymphoid tissue(MALT)(n=7)and other rare types(n=12).During the 1-112-month follow-up of 10 of the 19 patients,1 died at 1 month af-ter diagnosed with prostatic B-lymphoblastic lymphoma(B-LBL)and another 1 died at 50 months after diagnosed with testicular DLBCL.Conclusion:MGSL is rare clinically,mainly of the DLBCL type pathologically,lacking specificity in clinical symptoms and imaging manifestation.The definite diagnosis of the malignancy depends on histopathology combined with related molecular exami-nation and immunohistochemical labeling,and R-CHOP chemotherapy is the first choice for its treatment.

Objective:To explore the effects three of anesthetics(tribromoethanol,isoflurane,and pentobarbital so-dium)on the outcome of mice with post-stroke dysphagia(PSD)induced by photothrombosis(PT)method,and to e-valuate which anesthetic is more suitable for the preparation of this model.Methods:Sixty-six male C57BL/6J mice were divided into Tribromoethanol group,Isoflurane group,Pentobarbital sodium group and Sham group.The post-stroke dysphagia model was established by PT.Before and 5 min after modeling,a laser speckle imager was used to measure the regional cerebral blood flow(rCBF)decrease rate of mice and record the wake-up time of mice.Forty-eight hours after modeling,the mortality rate of PSD mice in three groups was recorded and the rCBF decrease rate was meas-ured again.The neurological function of mice was evaluated using the neurological deficit score,the water intake of mice was recorded using the 4-min drinking test,the infarct volume ratio was measured using the TTC staining method,and the swallowing counts induced by water administration was recorded using the multichannel physiological recorder MP160 and the myoelectric area of the swallowing muscle was calculated.Results:There was no statistical difference in the percentage of decrease in rCBF,infarct volume ratio,neurological deficit score,water intake,swallowing counts,and myoelectric area of swallowing muscle among the three groups of PSD mice 48 h after modeling(P＞0.05).Com-pared with the Tribromoethanol group and the Pentobarbital sodium group,the rCBF of the mice in the Isoflurane group decreased rapidly within 5 min(P＜0.05),and the mortality rate of the mice was lower and the awakening time was shorter.(P＜0.05).Conclusion:The use of different anesthesia will affect the mortality rate,wake-up time and the downward trend of rCBF within 48 h after modeling of PSD mice.Among the three anesthetics,isoflurane is more suit-able as an anesthetic for the PSD mouse model.

BACKGROUND:Percutaneous retrograde screws and minimally invasive percutaneous plates are extensively used in the treatment of unilateral pubic ramus fractures.However,the above internal fixations have the disadvantages of mistakenly penetrating the hip joint and damaging the medial pelvic trophoblastic artery.A new type of retrograde superior pubic ramus intramedullary nail offers advantages,such as fewer radiographic exposures and shorter surgery times,but the validation of the biomechanical properties of the three endoprostheses is lacking.OBJECTIVE:To compare the biomechanical differences post-treatment of upper and lower pubic ramus fractures using percutaneous retrograde screws,minimally invasive percutaneous plates,and retrograde superior pubic ramus intramedullary nail under various conditions through finite element analysis.METHODS:Pelvic CT data were collected from one volunteer and imported into Mimics 20,Geomagic Wrap 2021,and SolidWorks 2019 to create geometric models of three types of internal fixation for treating unilateral pubic ramus fractures:hollow screw group,plate group,and intramedullary nail group.Each model was imported into Ansys 2022 software,where it was set up in vertical,book-opening,and shear conditions for preprocessing and calculation to compare and analyze the mechanical stability of the implants.RESULTS AND CONCLUSION:(1)In vertical conditions,the biomechanical stability of the hollow screw treatment for unilateral pubic fractures was superior to that of the steel plate and intramedullary nail,with the smallest peak stress in the implant,which was four times lower compared to the other two groups.(2)In book-opening conditions,the steel plate treatment for unilateral pubic fractures showed better biomechanical stability,particularly in reducing stress at the fracture ends of the upper pubic branch,with stress values five times higher in the other two groups.(3)In shear conditions,the intramedullary nail treatment for unilateral pubic fractures exhibited good biomechanical stability,maintaining the best pelvic displacement,with a 25％greater displacement observed in the other two groups.(4)These findings reveal the biomechanical differences of different implants:the peak stress of implants is the smallest under vertical working conditions with percutaneous retrograde screws.Minimally invasive percutaneous plates reduce the stress at the broken end of superior pubic branch under open-book working condition.Retrograde superior pubic ramus intramedullary nail of superior pubic branch maintains pelvic displacement under shear working condition.The surgeon can combine the biomechanical differences of the implants with the actual situation of pubic injury in clinical practice to make the best implant treatment.

Objective:To analyze the epidemiological characteristics of cases involving monkey injuries at medical institutions surrounding Qianlingshan Park in Guiyang City, and to provide a reference basis for preventive measures to reduce monkey injuries and standardized post-exposure treatment.Methods:A retrospective cross-sectional study was conducted, collecting 1 900 cases of monkey-induced injuries in Qianlingshan Park treated at the outpatient clinic of Guizhou Provincial Center for Disease Control and Prevention and the Department of Surgery at Qianling Hospital, Guiyang City, from 2021 to 2024. Statistical analysis was performed using Pearson′s chi-square test.Results:Total of 1 900 cases of monkey-related injuries in Qianlingshan Park were collected from 2021 to 2024. The exposure time distribution exhibited significant seasonality, with 48.58% of cases occurring during July and August, totaling 923 cases, indicating a peak in the summer. There were 774 male patients and 1 126 female patients, with a ratio of 1∶1.45.and significant differences were observed between different age groups and genders (χ2=195.00, P<0.001), with the highest number of cases occurring in the 0-9 and 20-29 age groups, accounting for 22.05%(419 cases) and 21.79%(414 cases), respectively. The upper limbs were the most common injury site, accounting for 50.84% of the total cases(966 cases in total), with significant differences between gender and injury location (χ2=22.00, P<0.001), Among females, the proportion of injuries to the upper and lower limbs (30.11% and 16.47%, respectively) was higher than that among males (20.74% and 8.63%, respectively). The majority of injuries were classified as Grade Ⅲ, making up 57.38% of cases(1 069 cases in total). Self-treatment after exposure was the most common approach(60.44%), with significant differences observed between wound severity and treatment method (χ2=6.90, P=0.032), Patients with Grade Ⅱ and Grade Ⅲ wounds were more likely to choose self-management (26.84% and 33.23%, respectively) than outpatient management (15.14% and 24.15%). Approximately 98.05% (1 863 cases) of monkey-injured patients had received rabies vaccinations. Conclusions:This study analyzes monkey-related injuries in Qianlingshan Park from 2021 to 2024, clarifying the temporal distribution of injuries, demographic characteristics, injury sites, and treatment methods. The findings provide references for optimizing human-monkey conflict management and the prevention and control of zoonotic diseases in urban ecological parks.

Aim To investigate the neuroprotective effect of dioscin(DIO)on hippocampal neurons(HT22)after oxygen glucose deprivation/reoxygen-ation(OGD/R)and its possible mechanism.Methods HT22 cells were treated with 0,2.5,5,10,20,40,80,160,and 320 mg·L-1DIO for 24 h,and the cell proliferation rate was detected by CCK-8 method.The concentration that was non-toxic to HT 2 2 cells was se-lected for subsequent experiments.After OGD for 2 h,HT22 cells were randomly divided into the OGD/R group,1.25,2.5,and 5 mg·L-1DIO group,and posi-tive control group.HT22 cells were taken as the con-trol group.After drug intervention for 24 h,the cell proliferation rate was detected by CCK-8 method;the LDH release was detected by colorimetry;the cell ap-optosis rate was detected by TUNEL method;the ex-pression of proteins related to PARP-1/AIF pathway and caspase pathway was detected by Western blot.Results DIO intervention significantly upregulated the expression of AIF protein in mitochondria and PAR protein in nucleus of HT22 cells after OGD/R,and sig-nificantly downregulated the release of LDH,neuronal apoptosis rate,total protein expression of AIF and PAR,PARP-1,AIF in nucleus and protein expression of PAR protein in mitochondria,while the expression of Bax and caspase-3 proteins was not significantly differ-ent from that in the OGD/R group.Conclusion DIO can alleviate the apoptosis of HT22 cells induced by OGD/R by regulating the expression and translocation of proteins related to the PARP-1/AIF pathway,thus playing a neuroprotective role.

Hepatitis E is the liver inflammation caused by a hepatitis E virus infection.Immunocompetent patients with acute hepatitis E can spontaneously clear the infection,whereas immunosuppressed patients may not be able to clear the hepatitis E virus infection and develop chronic hepatitis.Most patients with hepatitis E are asymptomatic and present only with mild and persistent liver function abnormalities.This article reports a case of hepatitis E in an immunocompetent adult with elevated aminotransferases as the main manifestation.Hepatic fibrosis was detected by hepatic puncture biopsy.This report aims to remind other physicians to evaluate liver fibrosis when encountering acute hepatitis E,especially in patients with chronic liver disease.

Objective To develop a composite nutritional preparation that can effectively improve exercise performance under calorie restriction(CR)condition.Methods A total of 24 male C57BL/6J mice(weighing 23～26 g,8 weeks old)were randomly divided into control group(CON),CR,CR+basal nutrient group(CRN1),and CR+compound nutrient group(CRN2).All groups underwent moderate-intensity running training 5 d per week,for totally 3 weeks.The grip strength of the forelimbs were measured weekly,and in 3 weeks after training,exhaustion and post-exhaustion distance tests were conducted to evaluate exercise performance.Blood biochemical indicators,levels of skeletal muscle and liver redox biomarkers,and histopathological conditions were measured and observed.Results After 21 d of intervention,the CR group and CRN1 group had the post-exhaustion running distance prolonged by 278%and 289%,respectively,reduced blood glucose level,and decreased muscle mass,subcutaneous fat and epididymal fat mass when compared with the CON group(P<0.05).Compared with the CON group,the CRN1 and CRN2 groups demonstrated significantly higher gastrocnemius glycogen content.The CRN2 group obtained even longer post-exhaustion distance(increased by 52%and 36%respectively,compared with the CON group and CRN1 group,P<0.05),enhanced grip strength of the forelimbs(raised by 9%,17%and 15%,respectively than the CON,CR and CRN1 groups,P<0.05),elevated brown fat mass(compared to the CON group and CRN1 group,P<0.05),increased blood glucose level(compared to the CRN1 group,P<0.05),decreased blood low-density lipoprotein cholesterol level(compared to the CON and CR groups,P<0.05),and increased glutathione peroxidase content in the gastrocnemius muscle(compared to the CON group,P<0.05).Conclusion Supplementing with compound nutritional supplements in mice under CR can promote exercise performance,including improving fatigue recovery after exhaustive exercise and enhancing forelimb grip strength.

OBJECTIVE: To observe change in serum growth differentiation factor 11 (GDF11) and killer cell lectin-like receptor B1 (KLRB1), to construct a nomogram model for 28-day death in patients with septic shock, and to explore its predictive value. METHODS: A prospective observational study was conducted. The patients with septic shock admitted to the emergency intensive care unit (ICU) of Cangzhou Central Hospital from September 2023 to March 2025 were selected as the septic shock group, the patients with sepsis admitted to the emergency general ward during the same period were selected as the sepsis group, and healthy individuals undergoing physical examination during the same period were selected as the control group. On the day of hospital admission or physical examination for the research subjects, the levels of serum GDF11 and KLRB1 were detected by enzyme-linked immunosorbent assay (ELISA). The patients with septic shock were divided into survival and death groups based on their 28-day survival status. The patients' gender, age, past medical history, infection site, severity of illness, mechanical ventilation, blood purification, infection indicators, biochemical indicators, coagulation function indicators, and blood lactic acid (Lac) were collected. The clinical data of the patients with septic shock between the two groups with different prognoses were compared. Multivariate Logistic regression analysis was used to screen the risk factors for 28-day death in patients with septic shock, and bivariate Pearson correlation analysis was conducted. A nomogram model was constructed based on the risk factors for 28-day death in patients with septic shock. The discrimination and calibration of the nomogram model were evaluated using the receiver operator characteristic curve (ROC curve), Hosmer-Lemeshow goodness-of-fit test, and calibration curve. The clinical utility of the model was evaluated using clinical decision curve analysis (DCA). RESULTS: A total of 168 patients in the emergency ICU were enrolled in the septic shock group, 40 patients in the emergency general ward were enrolled in the sepsis group, and 40 healthy individuals were enrolled in the control group. Compared with the healthy control group, the serum GDF11 levels in the sepsis and septic shock groups were significantly increased (μg/L: 13.09±3.51, 19.28±5.36 vs. 4.17±0.92, both P < 0.05), and the serum KLRB1 levels were significantly decreased (ng/L: 57.36±11.28, 45.52±9.07 vs. 84.19±17.16, both P < 0.05), with more significant changes in the septic shock group (both P < 0.05). Among the 168 patients with septic shock, 96 survived and 72 died within 28 days. Compared with the survival group, the serum GDF11 level in the death group was significantly increased (μg/L: 24.24±4.81 vs. 15.56±4.62, P < 0.05), and the serum KLRB1 level was significantly decreased (ng/L: 28.53±8.69 vs. 58.26±9.45, P < 0.05). There were also statistically significant differences in sequential organ failure assessment (SOFA) score, acute physiology and chronic health evaluation II (APACHEII) score, procalcitonin (PCT), activated partial thromboplastin time (APTT), D-dimer, and Lac between the two groups. Multivariate Logistic regression analysis showed that SOFA score [odds ratio (OR) = 1.96, 95% confidence interval (95%CI) was 1.38-3.65), Lac (OR = 1.38, 95%CI was 1.09-2.01), GDF11 (OR = 1.54, 95%CI was 1.21-2.33) and KLRB1 (OR = 0.64, 95%CI was 0.41-0.78) were independent risk factors for 28-day death in patients with septic shock (all P < 0.05). Bivariate Pearson correlation analysis showed that SOFA score was significantly positively correlated with Lac and GDF11 (r value was 0.37 and 0.58, respectively, both P < 0.05), and significantly negatively correlated with KLRB1 (r = -0.72, P < 0.05). A nomogram model was constructed based on the risk factors for 28-day death in patients with septic shock. ROC curve analysis showed that the area under the ROC curve (AUC) of the nomogram model for predicting 28-day death in patients with septic shock was 0.963 (95%CI was 0.929-0.990), indicating that the model had good discrimination and predictive ability. The Hosmer-Lemeshow goodness-of-fit test (χ ² = 9.578, P = 0.295) and calibration curve indicated that the predicted values of the model were in good agreement with the actual values. DCA indicated that the model provided a high net benefit for clinical decision-making. CONCLUSIONS The serum GDF11 level was significantly increased and the KLRB1 level was significantly decreased in patients with septic shock. The nomogram model based on GDF11 and KLRB1 could more accurately evaluate the 28-day death of patients with septic shock.
