Objective To systematically evaluate the risk factors for postoperative delirium (POD) in patients undergoing pneumonectomy. Methods PubMed, Web of Science, Cochrane Library, CNKI, Wanfang, and VIP databases were searched from the inception to November 7, 2024 for cross-sectional studies, case-control studies, and cohort studies on POD in patients undergoing pneumonectomy. Two researchers independently screened the literature, extracted data, and evaluated the quality of the literature. RevMan 5.4.1 software was used for meta-analysis. The Newcastle-Ottawa Scale (NOS) was used to evaluate the quality of the literature. Results A total of 12 studies were included, with 5 574 patients. The NOS scores of the literature were all≥6 points. Meta-analysis results showed that age (≥60 years) [OR=2.43, 95%CI (2.01, 2.93), P<0.01], American Society of Anesthesiologists (ASA) classification (Ⅳ) [OR=8.74, 95%CI (5.23, 14.61), P<0.01], history of diabetes [OR=12.81, 95%CI (10.45, 15.71), P<0.01], history of cerebrovascular disease [OR=3.00, 95%CI (2.46, 3.67), P<0.01], depression [OR=7.27, 95%CI (5.46, 9.67), P<0.01], squamous cell carcinoma [OR=4.79, 95%CI (1.83, 12.51), P<0.01], malnutrition [OR=5.25, 95%CI (3.35, 8.25), P<0.01], sleep disorders [OR=2.79, 95%CI (2.28, 3.42), P<0.01], and duration of one-lung ventilation during surgery [OR=1.32, 95%CI (1.11, 1.57), P<0.01] were all risk factors for POD, while high body mass index (BMI) [OR=0.96, 95%CI (0.95, 0.97), P<0.01] was a protective factor for POD. Conclusion Age (≥60 years), ASA classification (Ⅳ), history of diabetes, history of cerebrovascular disease, depression, squamous cell carcinoma, malnutrition, sleep disorders, and duration of one-lung ventilation during surgery are independent risk factors for POD, while high BMI is a protective factor.

Objective To understand the epidemiological characteristics of severe congenital heart dis-ease in Chongqing City during 2007-2023 to provide a basis for its comprehensive prevention and control measures.Methods Based on hospital monitoring data,453 children patients with severe congenital heart dis-ease monitored by the birth defects monitoring institutions in Chongqing city from January 2007 to December 2023 were included in the study.They were grouped by year,perinatal infants gender,maternal permanent res-idence(urban/rural),maternal age,different regions and other categories.The χ2 test was used to analyze the difference in the incidence rate of different categories of severe congenital heart diseases,and the Joinpoint re-gression model was used to analyze the change trend.Results A total of 1 468 005 perinatal neonates were monitored in Chongqing City during 2007-2023 and 453 cases of severe congenital heart disease were found,with an incidence rate of 3.09/10 000,in which the incidence rate of atrioventricular septal defect was 2.16/10 000,the incidence rate of tetralogy of fallot was 0.66/10 000 and the incidence rate of transposition of great ar-teries was 0.27/10 000.The total incidence rate of cities and towns was higher than that in the countryside(χ2=64.08,P<0.001),the urban area was higher than the Chongqing southeast and Chongqing northeast towns cluster(χ2=49.34,P<0.001),the female was higher than the male(χ2=5.63,P=0.018).The inci-dence rates in different ages groups showed the U shape distribution(χ2=31.63,P<0.001).The incidence rate of the pregnant women<20 years old group and pregnant women≥35 years old group was higher,which of the 25-29 years old group was lower.The incidence rate of severe congenital heart disease in Chongqing City during 2007-2023 appeared the turning point,which during 2007-2016 was gradually increased(APC=-15.95),and which during 2016-2023 was gradually decreased(APC=-15.36).Conclusion The incidence rate of severe congenital heart disease in Chongqing city during 2007-2023 was increased first and then de-creased,moreover there were differences in time,region and population.

T-cell acute lymphoblastic leukemia (T-ALL) is a highly aggressive hematologic malignancy with a poor prognosis, despite advancements in treatment. Many patients struggle with relapse or refractory disease. Investigating the role of the super-enhancer (SE) regulated gene ubiquitin-specific protease 20 (USP20) in T-ALL could enhance targeted therapies and improve clinical outcomes. Analysis of histone H3 lysine 27 acetylation (H3K27ac) chromatin immunoprecipitation sequencing (ChIP-seq) data from six T-ALL cell lines and seven pediatric samples identified USP20 as an SE-regulated driver gene. Utilizing the Cancer Cell Line Encyclopedia (CCLE) and BloodSpot databases, it was found that USP20 is specifically highly expressed in T-ALL. Knocking down USP20 with short hairpin RNA (shRNA) increased apoptosis and inhibited proliferation in T-ALL cells. In vivo studies showed that USP20 knockdown reduced tumor growth and improved survival. The USP20 inhibitor GSK2643943A demonstrated similar anti-tumor effects. Mass spectrometry, RNA-Seq, and immunoprecipitation revealed that USP20 interacted with hypoxia-inducible factor 1 subunit alpha (HIF1A) and stabilized it by deubiquitination. Cleavage under targets and tagmentation (CUT&Tag) results indicated that USP20 co-localized with HIF1A, jointly modulating target genes in T-ALL. This study identifies USP20 as a therapeutic target in T-ALL and suggests GSK2643943A as a potential treatment strategy.

OBJECTIVES: To explore the expression profile of circular RNAs (circRNAs) and their potential roles in prognosis and progression of Wilms' tumor (WT). METHODS: Four pairs of WT and adjacent tissues were collected for high-throughput circRNA sequencing to identify the differentially expressed circular RNAs. RT-qPCR was used to verify the expression levels of the top 6 candidate circRNAs in the clinical samples. hsa_circ_0001900 was selected for analysis of its correlation with clinicopathological features and prognosis in 34 patients with WT. Sanger sequencing and RNase R digestion experiments were used to verify the cycling site and structural stability of hsa_circ_0001900 molecule. RESULTS: A total of 23 978 circular RNA molecules were identified in WT tissues by high-throughput circular RNA sequencing, and among them 614 were differentially expressed in WT. hsa_circ_0001900 showed the highest expression level among the differentially expressed circRNAs, which was consistent with the findings in clinical tumor samples and the sequencing results. Correlation analysis showed that hsa_circ_0001900 expression level was positively correlated with WT volume, and the children with high hsa_circ_0001900 expression had a lowered recurrence-free survival rate. The results of Sanger sequencing verified the circular splice site sequence of the molecule, and Rnase R digestion assay confirmed its stable covalent structure. CONCLUSIONS This study presents a comprehensive expression profile of circular RNAs in WT, and the expression level of hsa_circ_0001900 is related to the size of WT and the patients' prognosis, suggesting its possible role as a key driving gene in WT progression.

Stromal interaction molecules (STIM)s are Ca²⁺ sensors in internal Ca²⁺ stores of the endoplasmic reticulum. They activate the store-operated Ca²⁺ channels, which are the main source of Ca²⁺ entry in non-excitable cells. Moreover, STIM proteins interact with other Ca²⁺ channel subunits and active transporters, making STIMs an important intermediate molecule in orchestrating a wide variety of Ca²⁺ influxes into excitable cells. Nevertheless, little is known about the role of STIM proteins in brain functioning. Being involved in many signaling pathways, STIMs replenish internal Ca²⁺ stores in neurons and mediate synaptic transmission and neuronal excitability. Ca²⁺ dyshomeostasis is a signature of many pathological conditions of the brain, including neurodegenerative diseases, injuries, stroke, and epilepsy. STIMs play a role in these disturbances not only by supporting abnormal store-operated Ca²⁺ entry but also by regulating Ca²⁺ influx through other channels. Here, we review the present knowledge of STIMs in neurons and their involvement in brain pathology.

It is believed that the occurrence and development of squamous cell carcinoma （SCC） is closely associated with inflammatory responses. The theory of fire and heat， advocated by LIU Wansu， provides significant clinical guidance for understanding the pathogenesis and treatment of SCC. Based on this theory， the pathological mechanisms and clinical characteristics of SCC at different stages were analyzed. In the precancerous and early stages， the primary pathogenesis is qi stagnation leading to internal generation of constrained heat； in post-surgery， the condition shifts to qi deficiency with latent yin fire； during the treatment phase， the pathogenesis involves accumulation of pathogenic factors， excess toxins， and severe heat toxicity； in the late stage， the main pathology is yin deficiency with toxic heat， and phlegm-stasis obstruction of the internal organs. Corresponding stage-based treatment strategies are proposed. In the early stage， regulating qi movement to dissipate constrained heat； for post-surgery， tonifying qi and raising yang to dispel latent fire； during treatment stage， clearing heat and detoxifying to eliminate cancerous toxins； and in the late stage， nourishing yin and unblocking the bowels to clear deficiency heat.

Objective:To analyze the association between continuity of consultation and the management of glycosylated hemoglobin (HbA1c) in diabetes patients contracted by family doctors.Methods:This study was a cross-sectional study. From May 2022 to October 2022, three community health service centers in the urban area of Beijing were selected by convenient sampling. A total of 360 diabetes patients were selected by simple random sampling from the selected centers. Extraction of data from electronic health records were conducted to collect patient characteristics, information on the continuity evaluation indicators for patient visits (usual provider of care, UPC) in 2021 and information of monitoring and control indicators for HbA1c in 2021. The monitoring and control of HbA1c in patients with different continuity of consultations were compared. Chi-square test and logistic regression analysis were used to determine the association between continuity of consultation and HbA1c management (i.e., HbA1c monitoring and control).Results:Of the 360 patients, 167 (46.4%) were male; the age was 68.0 (60.0, 74.0) years and the number of years since diagnosis was 11.0 (7.0, 17.0) years. One hundred and fifty-nine patients (44.1%) had UPC scores below 30%, 101 patients (28.1%) had UPC scores between 30% and 50%, and 100 patients (27.8%) had UPC scores above 50%. The compliance rate for HbA1c monitoring was 66.4% (239/360), and the compliance rate for HbA1c control was 45.8% (165/360). When the UPC score was less than 30%, between 30%-50%, and greater than 50%, the HbA1c monitoring compliance rates were 53.5% (85/159), 73.3% (74/101), and 80.0% (80/100), respectively, and the HbA1c control compliance rates were 37.7% (60/159), 51.5% (52/101), and 53.0% (53/100), respectively, and the differences were statistically significant ( χ2=22.36, 7.57, P<0.05). As the UPC score increased, the likelihood of achieving HbA1c monitoring ( OR=1.020, 95% CI:1.009-1.030 , P<0.001) and control ( OR=1.012, 95% CI:1.003-1.021 ,P=0.008) targets increased. Conclusion:There is an association between the continuity of consultation and the management of HbA1c.

BACKGROUND:Traditional Chinese medicine has been proved to have a significant role in anti-osteoporosis,and the effectiveness and mechanism of Ligustri Lucidi Fructus and its the active ingredients against osteoporosis have gradually gained the attention of scholars.OBJECTIVE:To analyze and summarize the research progress of Ligustri Lucidi Fructus and its active ingredients against osteoporosis in vitro and in vivo.METHODS:We searched the relevant literature included in CNKI and PubMed databases using the search terms of"Osteoporosis,Bone marrow mesenchymal stem cells,Osteoblast,Osteoclast,Ligustri Lucidi Fructus,Signal path"in Chinese and English,respectively.According to the needs of the research,we established the corresponding criteria and screened the literature.A total of 82 papers were included in the final review.RESULTS AND CONCLUSION:(1)The active ingredients of Ligustri Lucidi Fructus that exert anti-osteoporotic effects in vitro and in vivo mainly involve the following:Salidroside activates the Wnt/β-catenin signaling pathway by inhibiting the expression of Sclerostin and Dickkopf-related protein 1.This activation process enhances the expression of phosphorylated low-density lipoprotein receptor-related protein 6 in ovariectomized rats and primary osteoblasts,while decreasing the expression of glycogen synthase kinase 3β.Further,it promotes the expression of β-catenin,runt-related transcription factor 2 and cellular myelocytomatosis oncogene in the nucleus,thereby promoting the bone formation capacity of osteoblasts.The advantage is that it acts directly on osteoblasts to promote bone formation,which provides a new strategy for the treatment of osteoporosis.(2)Olive bittersweet significantly increases bone mineral density and regulates bone metabolism by decreasing terminal interleukin-6 and alkaline phosphatase concentrations in Sprague-Dawley rats.In vitro experiments showed that olive bittersweet promotes the proliferation of osteoblasts and up-regulates the protein and mRNA expression of osteoprotegerin,while inhibiting the protein and mRNA expression of receptor activator of nuclear factor-κB ligand.This mechanism of action is closely related to the regulation of the balance of the osteoprotegerin/receptor activator of nuclear factor-κB ligand system,demonstrating the advantage of increasing bone mineral density and maintaining bone health by regulating factors related to bone metabolism,but there is no significant effect on Ca2+concentration,which may limit its use in some specific types of osteoporosis.(3)By decreasing the expression of phosphatidylinositol 3 kinase,reducing the phosphorylation of protein kinase B and the expression of osteoclast-specific marker protein c-Fos,pineconiferin effectively inhibits the activation of phosphatidylinositol 3 kinase/protein kinase B/c-Fos pathway in osteoclasts.This inhibition reduces the proliferation and maturation of osteoclasts,which can help to reduce bone resorption.The advantage of this inhibition is that it can directly target osteoclasts,which provides a new target for osteoporosis treatment.However,the specific regulatory mechanism of osteoclasts needs to be studied in depth,and its long-term effect and safety need to be further evaluated.(4)The active ingredients of Ligustri Lucidi Fructus have shown good therapeutic effects on osteoporosis,but their mechanism of action is complex,involving the interaction of multiple genes,proteins and signaling pathways.In the future,large-scale clinical trials need to be carried out to verify its effectiveness and safety,and the strategy of combining the active ingredients of Ligustri Lucidi Fructus with other drugs needs to be further explored in order to obtain better therapeutic effects.

This study explored the effect of the Mycobacterium tuberculosis(Mtb)PE/PPE family protein PE_PGRS37 on the growth of Mycobacterium smegmatis(Ms)and macrophage autophagy during Mtb infection.The pe_pgrs37 gene was amplified from Mtb genome through PCR,and the recombinant vector pAIN-PE_PGRS37 was successfully constructed through homologous recombi-nation.pAIN-PE_PGRS37 and pAIN were integrated into Ms through electroshock to construct pAIN-PGRS37/Ms and pAIN/Ms re-combinant bacteria.Western blotting indicated that the PE_PGRS37 protein was correctly expressed in pAIN-PE_PGRS37/Ms.The re-combinant bacteria were inoculated in 7H9/7H10 medium,and their colony morphology and growth curves were observed.No signifi-cant difference in colony morphology was observed between pAIN-PE_PGRS37/Ms and pAIN/Ms.The growth rate significantly in-creased between 10 and 16 h,and a plateau was reached at 26 h.After infection of U937 cells with pAIN-PE_PGRS37/Ms and pAIN/Ms,macrophage autophagy flow was detected with western blotting and immunofluorescence.In the pAIN-PE_PGRS37/Ms-infected group,compared with the pAIN/Ms-infected group,macrophage LC3-II and p62 protein expression was significantly up-regulated(P<0.001)and inhibited autophagosome and lysosome fusion.The intracellular survival of the recombinant bacteria was detected through colony counting,and pAIN-PE_PGRS37/Ms showed significantly greater survival in macrophages at 12 h,24 h,and 48 h than pAIN/Ms(P<0.05).Our results suggested that PE_PGRS37 protein promotes Mycobacterium survival in macrophages by blocking macro-phage autophagy flow,thus inhibiting macrophage autophagy.

Objective:This study aimed to evaluate the effects of hypertensive disorders of pregnancy (HDP), including their clinical subtypes, on neonatal heel blood methionine levels and explore potential dose-effect relationships.Methods:A retrospective cohort study was conducted among 11 007 singleton pregnancies and their neonates delivered at Beijing Obstetrics and Gynecology Hospital, Capital Medical University, from July 2021 to October 2022. Participants were stratified into an HDP group [ n=992; 480 with gestational hypertension, 512 with preeclampsia (including 229 severe cases)] and a non-HDP control group ( n=10 015). Methionine concentrations were measured using tandem mass spectrometry from heel blood dried filter paper samples collected within 72 hours post-delivery. Statistical analyses included non-parametric tests to compare intergroup differences, multiple linear regression to evaluate the effects of HDP on methionine levels, and multivariate logistic regression to identify risk factors for hypermethioninemia (>50 μmol/L). Results:(1) Baseline data: Maternal age was higher in the HDP group compared to controls [33 (30-36) vs. 33 (30-35) years, Z=－2.29, P=0.022], with elevated pre-pregnancy body mass index (BMI) [23 (21-26) vs. 21 (20-23) kg/m2, Z=－17.15, P<0.001] and increased gestational hyperglycemia prevalence [26.5% (263/992) vs. 19.8% (1 986/10 015), χ2=27.95, P<0.001]. (2) Methionine level: Neonates in the HDP group exhibited higher methionine levels [25.96 (21.58-30.89) vs. 24.77 (20.45-29.53) μmol/L, Z=－5.26, P<0.001], with a severity-dependent gradient: gestational hypertension [25.83 (21.77-30.61)], preeclampsia [26.05 (21.23-31.11)], and severe preeclampsia [26.15 (21.25-32.13)] ( Z=2.97, 3.92, 2.26; all P<0.05). Trend analysis confirmed a dose-effect relationship between HDP and neonatal methionine ( χ2=7.82, P=0.005). (3) Multivariate analysis: After adjusting for confounding factors such as maternal age and BMI, HDP remained independently associated with elevated methionine levels ( β=0.93, 95% CI: 0.47-1.40, t=3.92, P<0.001) and increased hypermethioninemia risk ( OR=2.75, 95% CI: 1.13-6.68). Subgroup analysis revealed ORs of 3.20 (95% CI: 1.07-9.57) for gestational hypertension, 3.25 (95% CI: 1.09-9.72) for preeclampsia, and 5.23 (95% CI: 1.54-17.82) for severe preeclampsia (all P<0.05). (4) Neonatal outcomes: Neonates in the HDP group had lower birth weights [3 230 (2 910-3 560) vs. 3 335 (3 070-3 600) g, Z=－7.43, P<0.001] and higher fetal growth restriction rates [10.3% (102/992) vs. 3.1% (306/10 015), χ2=136.47, P<0.001]. Conclusions:HDP demonstrates an elevation of neonatal methionine levels, correlating with disease severity, particularly in severe preeclampsia. These findings underscore the necessity for enhanced metabolic monitoring and long-term follow-up in offspring of mothers with HDP, especially those with severe preeclampsia.
