Purpose This study aims to investigate the clinicopathological features of diffuse pulmonary menin-gotheliomatosis(DPM).Methods The clinical data of 10 patients with DPM undergoing video-assisted thoracic sur-gery(VATS)were collected,and their clinical and pathological characteristics were analyzed using immunohistochem-istry.Results The detection rate of DPM was 1.19‰,with 90％of the patients being female.DPM predominantly occurred in the age range of 40-60 years,with an average age at diagnosis of 50.7 years.Most patients had no smok-ing history.Pathological diagnosis combined with imaging findings was the main method for diagnosing DPM.80％of the patients were prone to concurrent early-stage invasive pulmonary adenocarcinoma.Laboratory indicators,including pulmonary function,were generally normal.Chest CT showed diffuse multiple ground-glass opacity or cystic nodules in both lungs,with the number of nodules in both lungs ranging from dozens to hundreds,and the maximum diameter of the nodules was 2-6 mm.The median volume and CT value of the pulmonary nodules were 35.32 mm3 and-566 HU,respectively.Pathological features mainly included multiple meningothelial-like nodules observed under the micro-scope.Immunophenotypically,CD56,EMA,PR,and vimentin were often positive.Conclusion DPM is a rare lung disease with no obvious clinical symptoms,and is more common in middle-aged and elderly women.Diffuse multiple nodules in both lungs are its main imaging features.Most DPM patients are complicated with lung adenocarcinoma,and regular follow-up is recommended.

Objective To investigate the influence of preoperative blood lipid levels on postoperative recovery in patients with acute Achilles tendon rupture(AATR).Methods The clinical data of 353 AATR patients treated in Department of Orthopaedics Trauma of our hospital from Jan.2021 to Jan.2024 were retrospectively analyzed,including general clinical information and preoperative fasting blood biochemistry indices.Patients'Achilles tendon total rupture score(ATRS)and American Orthopaedic Foot and Ankle Society(AOFAS)ankle-hindfoot score were recorded 6 months postoperatively.Postoperative recovery was categorized as favorable if ATRS≥80 and poor if ATRS＜80;similarly,recovery was considered favorable if AOFAS score≥90 and poor if AOFAS score＜90.Univariate and multivariate logistic regression analyses were done to investigate the influencing factors of patients'postoperative recovery.Results When categorized by ATRS,patients in the favorable postoperative recovery group exhibited significantly lower serum levels of triglyceride(TG),total cholesterol(TC),and low-density lipoprotein(LDL)compared to the poor postoperative recovery group(all P＜0.05).Similarly,when categorized by AOFAS score,the favorable postoperative recovery group had lower serum TG and TC levels than the poor postoperative recovery group(both P＜0.05).Univariate logistic regression analysis demonstrated that in the ATRS grouping,elevated serum levels of TG,TC and LDL were significantly associated with an increased risk of poor postoperative recovery in AATR patients(all P＜0.05).Similarly,in the AOFAS score grouping,elevated serum levels of TG and TC were significantly correlated with an increased risk of poor postoperative recovery in AATR patients(both P＜0.05).Multivariate logistic regression analysis further identified that high serum LDL level was an independent predictor of poor postoperative recovery in AATR patients(P＜0.05).Conclusion High preoperative serum LDL level is associated with an increased risk of poor postoperative recovery in AATR patients.Therefore,preoperative blood lipid management in AATR patients may have positive effects on postoperative functional recovery.

The comparison between traditional Chinese medicine Jinzhen oral liquid (JZOL) and Western medicine in treating children with acute bronchitis (AB) showed encouraging outcomes. This trial evaluated the efficacy and safety of the JZOL for improving cough and expectoration in children with AB. 480 children were randomly assigned to take JZOL or ambroxol hydrochloride and clenbuterol hydrochloride oral solution for 7 days. The primary outcome was time-to-cough resolution. The median time-to-cough resolution in both groups was 5.0 days and the antitussive onset median time was only 1 day. This randomized controlled trial showed that JZOL was not inferior to cough suppressant and phlegm resolving western medicine in treating cough and sputum and could comprehensively treat respiratory and systemic discomfort symptoms. Combined with clinical trials, the mechanism of JZOL against AB was uncovered by network target analysis, it was found that the pathways in TRP channels like IL-1β/IL1R/TRPV1/TRPA1, NGF/TrkA/TRPV1/TRPA1, and PGE2/EP/PKA/TRPV1/TRPA1 might play important roles. Animal experiments further confirmed that inflammation and the immune regulatory effect of JZOL in the treatment of AB were of vital importance and TRP channels were the key mechanism of action.

OBJECTIVE: This study investigates the sleep-modulating effects of ginsenoside Rg1 (Rg1, C₄₂H₇₂O₁₄), a key bioactive component of ginseng, and elucidates its underlying mechanisms. METHODS: C57BL/6J mice were intraperitoneally administered doses of Rg1 ranging from 12.5 to 100 mg/kg. Sleep parameters were assessed to determine the average duration of each sleep stage by monitoring the electrical activity of the brain and muscles. Further, orexin neurons in the lateral hypothalamus (LH) and corticotropin-releasing hormone (CRH) neurons in the paraventricular hypothalamic nucleus (PVH) were ablated using viral vector surgery and electrode embedding. The excitability of LH^orexin and PVH^CRH neurons was evaluated through the measurement of cellular Finkel-Biskis-Jinkins murine osteosarcoma viral oncogene homolog (c-Fos) expression. RESULTS: Rg1 (12.5-100 mg/kg) augmented the duration of non-rapid eye movement (NREM) sleep phases, while reducing the duration of wakefulness, in a dose dependent manner. The reduced latency from wakefulness to NREM sleep indicates an accelerated sleep initiation time. We found that these sleep-promoting effects were weakened in the LH^orexin and PVH^CRH neuron ablation groups, and disappeared in the orexin and CRH double-ablation group. Decreased c-Fos protein expression in the LH and PVH confirmed that Rg1 promoted NREM sleep by inhibiting orexin and CRH neurons. CONCLUSION Rg1 increases the duration of NREM sleep, underscoring the essential roles of LH^orexin and PVH^CRH neurons in facilitating the sleep-promoting effects of Rg1.

Chronic mountain sickness (CMS) or Monge syndrome is a disease that is prevalent at altitude above 2 500 meters. High altitude polycythemia (HAPC) is one subtype of CMS. EPAS1 and EGNL1 are the most critical high-altitude adaptation genes in the genome of the Tibetan population. The HIF-PHD-VHL system plays an important role in the pathogenesis of HAPC. The protease encoded by the SENP1 gene regulates hypoxia related transcription factors such as HIF and GATA to affect the expression of EPO or EPOR involved in red blood cell generation. With the development of genetic testing and omics technology, new progress in the fields of metabolomics, proteomics and metabolomics has been made in the pathogenesis of HAPC. The above new research results provide a preliminary basis for bone marrow hematoecology and hematopoietic regulation of HAPC. The diagnostic criteria for CMS have certain limitations, especially in patients with excessive erythrocytosis who should undergo genetic testing recommended for congenital and polycythemia vera. This article provides a review of the latest research on HAPC in various omics techniques, hematopoietic regulation and diagnostic processes which is more conducive to understand the pathogenesis. The clinical diagnosis of excessive erythrocytosis emphasizes the importance of genetic testing.

Objective:To investigate the laboratory detection methods for immune hemolytic transfusion reactions caused by anti-tigecycline antibody and the clinical diagnosis and treatment of one patient.Methods:The correlation between hemolysis-related laboratory indexes of the patient and the duration of medication was analyzed. Blood samples of the patient were tested using direct anti-human globulin test, free antibody test, and release test. Erythrocyte sensitization method and immune complexome analysis were used to detect the antibody against tigecycline in the serum of the patient. The properties and the titers of anti-tigecycline antibody were analyzed.Results:Anti-tigecycline antibody was found in the patient through the erythrocyte sensitization method and the immune complexome analysis, and the result of the direct anti-human globulin test was positive. The clinical symptoms and physical signs of the patient improved rapidly after withdrawal of tigecycline and blood transfusion. The patient was discharged after 14-day treatment with immunoglobulin and hormone.Conclusions:Tigecycline can cause hemolytic transfusion reactions. Serological tests are essential for the diagnosis of drug-induced hemolytic anemia. Withdrawal of medications and symptomatic treatment should be conduceted immediately when patients develop drug-related hemolytic anemia.

Objective:To explore the effects and mechanism of Bushen Tongluo Prescription in mechanical injury of rat endometrium.Method:A total of 60 female SD rats were divided into the blank group, model group, estradiol valerate group, and Bushen Tongluo Prescription group according to the random number table method, with 15 rats in each group.
