Objective To explore syndrome and treatment law of TCM in treating pediatric pneumonia convalescence;To provide references for clinical syndrome differentiation and treatment.Methods The relevant literature about TCM in treating pediatric pneumonia convalescence was retrieved from CNKI,SinoMed,VIP,Wanfang Data and PubMed from the establishment of the databases to December 31,2024.Diagnostic basis,syndrome elements and TCM prescription information were extracted.Excel 2021 was used for frequency statistics,SPSS Modeler 18.0 was used for association rule analysis,Gephi 0.10.1 was used to complete complex network analysis,and Origin 2025 was used for data visualization.Results A total of 171 articles were included.Diagnosis basis predominantly involved symptoms,signs and course of the disease.TCM syndrome element distribution predominantly involved the lung,spleen,qi deficiency,yin deficiency,phlegm,dampness,blood stasis and heat,often presenting as a mixture of deficiency and excess patterns.A total of 98 prescriptions were collected,with high-frequency herbs primarily including tonifying and deficiency-replenishing herbs,and phlegm-resolving and antitussive herbs.The herbal properties and tastes were mainly warm,neutral,slightly cold,and sweet,bitter,pungent,primarily associated with the lung and spleen meridians.Complex network analysis identified three core patterns of syndrome-herb interactions.Conclusion The diagnosis of pediatric pneumonia convalescence relies on symptoms,signs and course of the disease as key criteria.The syndrome is often characterized by a deficiency-excess complex.Treatment should integrate the dynamic interactions among syndrome elements and adjust the balance between reinforcing healthy qi and eliminating pathogens based on the proportional weight of deficiency and excess.For deficiency patterns,it is necessary to focus on tonifying qi and nourishing yin.For concurrent syndromes or pathological factors,additional methods such as resolving phlegm,clearing heat,regulating qi,drying dampness,promoting digestion,cooling blood,and activating blood circulation may be incorporated.

Otitis media is an infection of the middle ear mainly caused by bacteria, and current treatments rely heavily on antibiotics. However, the emergence of antibiotic-resistant bacterial strains seriously affects their efficacy. In our study, we found that extracellular vesicles (EVs) derived from human natural killer cells (NKs) inhibit the proliferation of both standard and levofloxacin (LVX)-resistant strains of Staphylococcus aureus in a dose-dependent manner. Moreover, compared to LVX, EVs were more effective at reducing effusion and rescuing hearing thresholds in animal models. For LVX-sensitive strains, EVs were significantly more effective in terms of curative time but not curative rate. For LVX-resistant strains, EVs were significantly more effective in terms of both curative rate and curative time when applied alone or applied jointly with LVX. In summary, we found that NK EVs are highly effective in treating otitis media, providing an alternative approach for treating this common disease.

Objective:To investigate the composition of immune cells and fibroblastic reticular cells (FRCs) in the lymph nodes (LNs) follicles of human immunodeficiency virus (HIV)-infected individuals with varying immune statuses, and their association with HIV replication.Methods:Neck LNs samples were collected from 4 treatment-naive, newly diagnosed HIV-infected individuals with diverse immune statuses. RNA in situ sequencing was employed, with imaging achieved via rolling circle amplification and fluorescence labeling. By integrating cell segmentation and nuclear staining, single-cell data from up to one hundred thousand cells were generated per paraffin tissue section. Using lymphoid follicles as the unit of analysis, compositional changes in immune cells and FRCs were characterized, and their correlations with viral replication were evaluated. Results:The peripheral blood CD4 + T cell counts of samples LN_1, LN_2, LN_3, and LN_4 exhibited a sequential decrease. A total of 31, 15, 16, and 18 structurally intact follicles were identified in each sample, respectively. In the follicles of LN_1, the proportion of HIV-replicating cells positively correlated with cDCs abundance ( R2=0.2, P=0.011), and HIV RNA signals were spatially colocalized with cDCs and FRCs. In the follicles of LN_2, HIV RNA molecules showed preferential enrichment within FRCs. In sample LN_3, HIV RNA enrichment was observed in both cDCs and CD4 + T cells. In sample LN_4, the proportion of cells with HIV replication was positively correlated with the proportions of the following cells: cDCs ( R2=0.38, P=0.006 4), CD4 + T cells ( R2=0.28, P=0.025), and FRCs ( R2=0.26, P=0.029), and HIV RNA molecules were detected in cDCs, CD4 + T cells, and FRCs. LN_1 and LN_2 samples showed a trend toward negative correlation between HIV-replicating cell proportion and CD8 + T cells proportion. LN_4 sample demonstrated a significant positive correlation between HIV-replicating cell proportion and CD8 + T cells proportion ( R2=0.23, P=0.046). Conclusions:RNA in situ sequencing technology reveals unique distribution patterns of immune cells and viral replication in LNs follicles of HIV-infected individuals. The follicular immune microenvironment exhibits distinct characteristics associated with peripheral blood CD4 + T cell counts, providing novel insights into the spatial dynamics of HIV persistence and immune cell interactions during infection.

Objective:To investigate the risk factors of diabetic kidney disease (DKD) in type 2 diabetes mellitus (T2DM) patients in plain-sand areas and loess hilly areas of Gansu province.Methods:A total of 1 599 T2DM patients who participated in chronic disease and risk factors monitoring and basic public health service management were selected by multi-stage stratified random sampling method in the sandy plain areas and loess hilly areas of Gansu province. Questionnaire survey, physical measurement and laboratory tests were performed. Multivariate binary logistic model was used to analyze the influencing factors.Results:The prevalence of DKD was 22.1% (174/787) among T2DM patients in the sandy plain areas and 19.1%(155/812) in the loess hilly area, respectively. Hypertension ( OR=3.022), hyperuricemia ( OR=2.114) and HbA1c≥7%( OR=2.231) were the risk factors for DKD in the plain-sand areas, and the risk of DKD increased with age. In the loess hilly areas, female sex ( OR=0.379) was the protective factor for DKD; while duration of disease≥10 years ( OR=2.476), hyperuricemia ( OR=1.907), HbA1c≥7% ( OR=1.927) were the risk factors for DKD; and the risk of DKD increased with the increase of age, and decreased with the increase of per capita monthly income. Conclusions:The prevalence of DKD and its influencing factors are different between sandy plain areas and loess hilly areas in Gansu province. The prevention and treatment of hypertension should be given more attention in sandy plain areas. In addition, the screening of DKD should be conducted among T2DM patients, particularly for those with old age, hyperuricemia and HbA1c≥7% in both areas of the province.

Objective:To investigate the risk factors for postoperative delirium in the elderly patients with hip fracture and to construct an online nomogram of the risk factors.Methods:Retrospectively analyzed were the data of 483 elderly patients with hip fracture who had been treated with artificial joint replacement from May 2020 to August 2021 at Department of Orthopaedics (Department of Joint Surgery), Jinling Hospital Affiliated to Medical College of Nanjing University. There were 166 males and 317 females, aged from 61 to 99 years (average, 82.1 years). Fracture types: 333 femoral neck fractures and 150 intertrochanteric fractures. The patients were divided into a delirium group ( n=149) and a delirium-free group ( n=334) according to whether postoperative delirium occurred after surgery. The 2 groups were compared in terms of general data like age, gender, body mass index, and concomitant diseases, as well as in terms of indexes like pre-operative albumin, preoperative hemoglobin, and postoperative C-reactive protein (CRP). Factors with P < 0.05 were included in the multi-factor logistic regression analysis to screen out the risk factors for postoperative delirium. The "rms" package of R software was used to draw the nomogram; the Bootstrap method was used to repeat the sampling 1,000 times for evaluation, calculation of the consistency index ( CI), and drawing of the ROC curve and correction curve; the decision curve was plotted using the "rmda" package. Results:There were significant differences between the delirium group and the delirium-free group in age, preoperative anxiety, Alzheimer＇s disease, history of cerebrovascular disease, preoperative albumin, intraoperative hypotension and postoperative CRP ( P < 0.05). The multifactorial logistic regression analysis showed that high age, preoperative anxiety, Alzheimer＇s disease, preoperative albumin < 35 g/L, and postoperative CRP ≥90 mg/L were the risk factors for postoperative delirium in the elderly patients with hip fracture after artificial joint replacement ( P < 0.05). The area under the ROC curve of the nomogram constructed by incorporating the risk factors for postoperative delirium was 0.894 (95% CI: 0.865 to 0.923) with a CI of 0.889; the calibration curve showed that the calibration curve of this nomogram model tended to be close to the ideal curve. The decision curve analysis showed that the threshold value was 0.01 to 1.00, showing the net benefit rate of this nomogram model > 0 when used to predict the postoperative delirium in the elderly patients with hip fracture. Conclusions:High age, preoperative anxiety, Alzheimer's disease, preoperative albumin < 35 g/L, and postoperative CRP ≥90 mg/L may be the risk factors for postoperative delirium in the elderly patients with hip fracture after artificial joint replacement. The online nomogram based on these factors demonstrates a good value in prediction of postoperative delirium.
