ObjectiveTo develop a classification model based on complete blood count （CBC） parameters combined with clinical factors to predict severe respiratory infections caused by Human adenovirus （HAdV） in pediatric patients. MethodsFrom September 2023 to September 2024， the CBC parameters and related clinical data from pediatric patients diagnosed with HAdV infection were collected. Principal component analysis and random forest models were used to identify potential predictors of severe cases. ResultsA total of 668 pediatric patients were included， with 564 cases assigned to the training cohort and 104 cases to the validation cohort. Severe cases were defined as pneumonia and/or fever lasting ≥5 days （pneumonia or prolonged fever， PorPF）. Principal component analysis and feature importance analysis （Mean Decrease Gini value） identified the monocytosis ratio （PMono）， red blood cell count （RBC）， and platelet count （PLT） as the most critical CBC parameters. Logistic regression analysis revealed that oxygen therapy （OR = 4.367， 95% CI： 1.568–12.161） and increased work of breathing （OR = 3.904， 95% CI： 2.146–7.101） were relative risk factors for PorPF. Meanwhile， higher PMono （OR = 0.696， 95% CI： 0.640–0.757）， RBC （OR = 0.201， 95% CI： 0.124–0.325）， and PLT （OR = 0.990， 95% CI： 0.987–0.994） were protective factors. When PMono was used as a predictive marker for PorPF， the area under the receiver operating characteristic curve （AUC） was 0.648 and 0.705， respectively. A random forest model incorporating four risk factors ［PMono， RBC， PLT， and hematocrit （HCT）］ was constructed to classify PorPF and general cases， achieving AUCs of 0.688 and 0.768， respectively. ConclusionsPMono， RBC， and PLT may serve as characteristic CBC indicators for predicting pneumonia or prolonged fever in children with HAdV infection. A risk factor model built using PMono， RBC， PLT， and HCT offers a relatively simple and accurate approach to predicting severe cases in pediatric HAdV infections.

Tuberculosis (TB) has one of the highest mortality rates among infectious diseases worldwide. The immune response in the host after infection is proposed to contribute significantly to the progression of TB, but the specific mechanisms involved remain to be elucidated. Single-cell RNA sequencing (scRNA-seq) provides unbiased transcriptome sequencing of large quantities of individual cells, thereby defining biological comprehension of cellular heterogeneity and dynamic transcriptome state of cell populations in the field of immunology and is therefore increasingly applied to lung disease research. Here, we first briefly introduce the concept of scRNA-seq, followed by a summarization on the application of scRNA-seq to TB. Furthermore, we underscore the potential of scRNA-seq for clinical biomarker exploration, host-directed therapy, and precision therapy research in TB and discuss the bottlenecks that need to be overcome for the broad application of scRNA-seq to TB-related research.

OBJECTIVE: To investigate the effectiveness of free palmaris longus tendon graft reconstruction in the treatment of gouty tophus erosion lesions in flexor tendon of wrist and hand. METHODS: A retrospective analysis was conducted on 8 patients with gouty tophus erosion lesions in flexor tendon of wrist and hand who underwent free palmaris longus tendon graft reconstruction between June 2017 and December 2023. All patients were male, aged 22-65 years, with an average of 45.9 years. The duration of gout history ranged from 2 to 18 years, with an average of 8.8 years. The duration from the discovery of gouty tophus to operation ranged from 12 to 26 months, with an average of 17.6 months. The gouty tophus eroded the flexor pollicis longus tendon in 4 cases, with Verdan flexor tendon zones being Ⅰ-Ⅱ in 1 case and Ⅳ-Ⅴ in 3 cases. The flexor digitorum profundus tendons were affected in 2 cases for the index finger, 1 for the middle finger, and 1 for the ring finger, all located in zone Ⅳ-Ⅴ. The long axis of the gouty tophus ranged from 2.3 to 4.5 cm, with an average of 3.4 cm. All 8 patients presented with limited finger flexion and extension. Among them, 4 cases were accompanied by median nerve compression symptoms, and 1 case had associated bone and joint destruction in the hand. The total active motion (TAM) of the affected finger was (81.3±30.2)° before operation according to the hand function evaluation criteria for tendon repair by the Chinese Society of Hand Surgery of the Chinese Medical Association, and the functional evaluation was poor. The harvested palmaris longus tendon intraoperatively was 7-9 cm in length. RESULTS: Surgical incisions in all 8 patients healed by first intention, with no infections, graft non-union, or significant adhesion complications. All patients were followed up 8-25 months, with an average of 14.8 months. Numbness symptoms resolved in all 4 patients who presented with median nerve compression symptoms. Patients did not experience wrist pain or other discomfort, and function was not compromised. At last follow-up, according to the hand function evaluation criteria for tendon repair by the Chinese Society of Hand Surgery of the Chinese Medical Association, the TAM of 8 patients was (197.5±55.8)°, which significantly improved when compared with that before operation ( t=11.638, P<0.001); the hand function of 1 patient with gouty tophus in zone Ⅰ-Ⅱ flexor pollicis longus tendon was good, and the other 7 patients were excellent. CONCLUSION Free palmaris longus tendon graft reconstruction demonstrates good effectiveness in treating gouty tophus erosion lesions in flexor tendon of wrist and hand.

Objective:To investigate the clinicopathological features and differential diagnosis of eosinophilic vacuolated tumor (EVT).Methods:Seven cases of EVT with characteristic morphology and unequivocal diagnosis from the Affiliated Hospital of Qingdao University (6 cases), Qingdao, China and the 971 Hospital of PLA Navy (1 case), Qingdao, China between January 2010 and December 2021 were subject to morphological and immunohistochemical analyses. Additionally, whole exome sequencing (WES) was performed in two cases. Twenty-two cases of renal oncocytoma (RO) and 17 cases of eosinophilic chromophobe renal cell carcinoma (eChRCC) diagnosed at the same time were used as controls.Results:Four males and three females with a mean age of 42 years (range: 29-61 years) were included in the study. The tumors were nodular and well-circumscribed, with sizes ranging from 1.5 to 4.5 cm. On cross-section, they appeared gray-red or gray-white, solid, and soft. Tumor cells were arranged in nests, solid sheets, and acinar or small vesicular structures. These cells exhibited eosinophilic cytoplasm with large, prominent clear vacuoles and round nuclei with prominent nucleoli. Perinuclear halos were focally present in four cases, while small tumor cells with sparse cytoplasm and hyperchromatic nuclei were seen in one case. No necrosis or mitosis was noted. Edematous stroma was detected in three cases. All tumors were positive for CD117 and Cathepsin K, but negative for vimentin and CK7. CK20 was positive in scattered individual cells, and Ki-67 positivity ranged from 1% to 4%. Point mutations in MTOR were identified in both patients who were subject to the molecular analysis. Statistical differences in the expression of Cathepsin K, CD10, S-100A1, and Cyclin D1 between EVT and RO ( P<0.05) were significant, so were the differences in the expression of Cathepsin K, CD10, CK7 and claudin 7 between EVT and eChRCC ( P<0.001). Seven patients were followed up for 4 to 96 months (mean, 50 months), with no recurrences or metastases. Conclusions:EVT is a rare renal tumor that shares morphological and immunophenotypic features with RO and eChRCC, and it is closely linked to the TSC/MTOR pathway. The presence of large prominent transparent vacuoles in eosinophilic cytoplasm along with conspicuous nucleoli is its key morphological characteristics. The use of combined immunohistochemical stains greatly aids in its diagnosis. Typically, the tumor exhibits indolent biological behaviors with a favorable prognosis.

Objective:To investigate the depersonalization status and to analyze the effect of workplace incivility perception, intrusive rumination and fear of negative evaluation on depersonalization in clinical nurses.Methods:In May 2019, 10 cities were selected as sampling cities by the method of grabbing random ball in Henan Province and Fujian Province. Using the stratified sampling, clinical nurses were selected as the research objects for a questionnaire survey in 22 tertiary hospitals and 23 secondary hospitals, included 1200 nurses. A total of 1200 questionnaires were issued and collected, and 1159 valid questionnaires were collected with effective recovery of 96.6%. Clinical nurses were investigated by Workplace Incivility Scale, Event Related Rumination Inventory, Fear of Negative Evaluation Scale, Maslach Burnout Inventory-General Survey. The demographic characteristics of nurses' depersonalization were compared and analyzed with t test and single factor analysis of variance. The influence mechanism of workplace incivility perception, intrusive rumination and fear of negative evaluation on depersonalization was analyzed with Bootstrap. Results:Depersonalization scores were (9.3±2.6) points, 467 of those had depersonalization symptoms in clinical nurses (40.3%). The scores of depersonalization of those with <3 years of service [ (10.5±2.9) points] was higher than those with 3-10 years [ (9.1±2.8) points] and 11-31 years [ (9.0±2.9) points]. The scores of depersonalization of those with monthly earning of <3000 yuan [ (10.1±2.8) points] was higher than those with 3000-7999 yuan [ (8.4±2.7) points] and 8000-12000 yuan [ (8.0±2.9) points]. The scores of depersonalization of clinical nurses in surgical departments [ (10.0±2.9) points] was higher than those in non-surgical departments [ (8.7±2.6) points]. The scores of depersonalization of clinical nurses in tertiary hospitals [ (10.0±2.7) points] was higher than those in secondary hospitals [ (8.6±2.8) points]. The differences were statistically significant ( P<0.05). Workplace incivility perception affected depersonalization through the single mediating role of intrusive rumination, fear of negative evaluation and the chain mediating role of intrusive rumination and fear of negative evaluation ( β=0.16, 0.17, 0.07, 95% CI: 0.15-0.20, 0.15-0.21, 0.03-0.09, P<0.05) . Conclusion:Workplace incivility perception directly or through the independent mediating effects of intrusive rumination or fear of negative evaluation, and the chain mediating effects of intrusive rumination and fear of negative evaluation influences the depersonalization of clinical nurses.

Objective: To study the relationship between compassion fatigue and workplace psychological violence, alexithymia, and empathy in clinical nurses. Methods: A total of 1 159 clinical nurses from 10 cities in Henan and Fujian Provinces were enrolled using the method of grabbing random balls. Questionnaires including Workplace Psychologically Violent Behaviors Instrument, the Toronto Alexithymia Scale, Jefferson Scale of Empathy Health Professionals, Professional Quality of Life Scale were used to investigate the status of workplace psychological violence, alexithymia, empathy, and compassion fatigue in participants. Bootstrap analysis was used to analyze the relationship between workplace psychological violence, alexithymia, empathy, and compassion fatigue scores. Results: The average score for workplace psychological violence among clinical nurses was (26.2±6.5), with 405 nurses (34.9%) having experienced workplace psychological violence. The scores for alexithymia, empathy and compassion fatigue were (58.3±12.3), (104.3±18.6) and (48.5±6.7) respectively. Mild compassion fatigue was detected in 34.9% of participants, while moderate to severe compassion fatigue accounted for 48.8%. Bootstrap test result showed that workplace psychological violence had a positive impact on compassion fatigue ［standardized effect value (β)=0.40, 95% confidence interval(CI)： 0.35-0.44］. Workplace psychological violence had separate mediating effects through alexithymia (β=0.15, 95%CI： 0.10-0.19), empathy (β=0.16, 95%CI： 0.10-0.21) , and a chain mediating effect through alexithymia and empathy on compassion fatigue (β=0.06, 95%CI： 0.03-0.09). Conclusion: Compassion fatigue symptoms are relatively common among clinical nurses. Experiencing workplace psychological violence directly affects compassion fatigue and can indirectly affect it through the mediating effects of alexithymia and empathy.

Objective To explore the current status of emotional exhaustion among clinical nurses and its relationship with work stress, thought suppression, difficulties in emotion regulation. Methods A totally of 1 159 clinical nurses from 10 cities in Henan Province and Fujian Province were enrolled as the research subjects using grabbing random balls method. And their status of work stress, thought suppression, difficulties in emotion regulation and emotional exhaustion were investigated by Depression-Anxiety-Stress Scale, White Bear Suppression Inventory, Brief Version of the Difficulties in Emotion Regulation Scale and Emotional Exhaustion Scale. Results The scores for work stress, thought suppression, difficulties in emotion regulation, emotional exhaustion were (23.5±3.8), (47.4±6.5), (54.1±7.2), (11.7±4.2), respectively.
