ObjectiveTo explore the clinical efficacy and mechanism of Bupi Qingfei prescription （BPQF） in treating stable bronchiectasis in the patients with syndromes of lung-spleen Qi deficiency and phlegm-heat accumulation in the lungs. MethodsA randomized， double-blind， placebo-controlled trial was conducted. Patients were randomized into BPQF and placebo control （PC） groups. On the basis of conventional Western medicine treatment， the BPQF granules and placebo were respectively administered at 10 g each time， twice a day， for a course of 24 weeks. The TCM symptom scores， Quality of Life Questionnaire for Bronchiectasis （QOL-B） scores， lung function indicators， T lymphocyte subsets， level of inflammatory factors in the sputum， level of neutrophil elastase （NE） in the sputum， and occurrence of adverse reactions were observed before and after treatment in the two groups. ResultsA total of 64 patients completed the study， encompassing 32 in the BPQF group and 32 in the PC group. After treatment， the BPQF group showed decreased TCM symptom scores （P<0.01）， increased QOL-B scores （P<0.01）， and declined levels of tumor necrosis factor （TNF）-α and NE （P<0.05， P<0.01）. The PC group showed decreased TCM symptom （except spleen deficiency） scores （P<0.01）， increased the QOL-B health cognition and respiratory symptom domain scores （P<0.05， P<0.01）， and a declined TNF-α level （P<0.01）. Moreover， the BPQF group had lower TCM symptom （except chest tightness） scores （P<0.05， P<0.01）， higher QOL-B （except treatment burden） scores （P<0.05， P<0.01）， and lower levels of interleukin-6 and TNF-α （P<0.05） than the PC group. Neither group showed serious adverse reactions during the treatment process. ConclusionBPQF can ameliorate the clinical symptoms of stable bronchiectasis patients who have lung-spleen Qi deficiency or phlegm-heat accumulation in the lungs by regulating the immune balance and inhibiting airway inflammatory responses.

The sixth edition of the Korean Medication Algorithm Project for Depressive Disorder (KMAP-DD) was published in 2025. This review compared KMAP-DD 2025 with four major international clinical practice guidelines: Canadian Network for Mood and Anxiety Treatments Clinical Guidelines for the Management of Major Depressive Disorders, National Institute for Health and Care Excellence Depression Guideline, Royal Australian and New Zealand College of Psychiatrists Clinical Practice Guidelines for Mood Disorders, and British Association for Psychopharmacology Guideline. While KMAP-DD is based on expert consensus, and others on evidence-based methods, overall treatment strategies for depressive episodes were fairly consistent. Especially, KMAP-DD 2025 offers more structured recommendations in areas lacking strong evidence, such as premenstrual dysphoric disorder, perinatal depression, and depression with medical comorbidities. KMAP-DD 2025 also reflected Korean clinical practice patterns emphasizing rapid symptom relief and early use of combination strategies. Despite limitations as a consensus-based guideline, KMAP-DD 2025 complements evidence-based approaches and provides practical, situation-specific guidance for real-world clinical decision-making in Korea.

Osteoporosis(OP) is a senile bone disease characterized by an imbalance between bone remodeling and bone formation. Targeting pathogenesis of kidney deficiency, spleen deficiency, and blood stasis, Bushen Jianpi Huoxue Decoction has a significant effect on the treatment of OP by tonifying kidney, invigorating spleen, and activating blood circulation. MicroRNA(miRNA) and the anti-apoptotic protein B-cell lymphoma-2-like protein 1(BCL2L1) are closely related to bone cell metabolism. Therefore, in this study, the binding of miR-140-5p to BCL2L1 was detected by dual luciferase assay and polymerase chain reaction(PCR). After silencing or overexpressing miR-140-5p, the apoptosis, autophagy, and osteogenic function of human fetal osteoblast cell line 1.19(HFOB1.19) were observed by flow cytometry and Western blot. Bushen Jianpi Huoxue Decoction-containing serum was prepared by intragastric administration of Bushen Jianpi Huoxue Decoction in rats. Different concentrations of Bushen Jianpi Huoxue Decoction-containing serum were used to treat HFOB1.19 with or without miR-140-5p mimic. The expression of osteogenic proteins in each group was observed, and the role of miR-140-5p/BCL2L1 in apoptosis and autophagy of HFOB1.19 was studied, along with the effect of Bushen Jianpi Huoxue Decoction on these processes. As indicated by the dual luciferase assay, miR-140-5p bound to BCL2L1. Flow cytometry and Western blot showed that miR-140-5p promoted apoptosis and inhibited autophagy in HFOB1.19. After intervention with high, medium, and low doses of Bushen Jianpi Huoxue Decoction-medicated serum, compared with the miR-140-5p NC group, the expression of osteocalcin(OCN), osteopontin(OPN), Runt-related transcription factor 2(RUNX2), and transforming growth factor beta 1(TGF-β1) decreased in the miR-140-5p mimic group, while the expression of bone morphogenetic protein 2(BMP2) showed no significant difference under high-dose intervention. Therefore, miR-140-5p/BCL2L1 can promote apoptosis and inhibit autophagy in HFOB1.19. Bushen Jianpi Huoxue Decoction can affect the osteogenic effect of miR-140-5p through BMP2.

PURPOSE: To investigate the protective effect of sub-hypothermic mechanical perfusion combined with membrane lung oxygenation on ischemic hypoxic injury of yorkshire brain tissue caused by traumatic blood loss. METHODS: This article performed a random controlled trial. Brain tissue of 7 yorkshire was selected and divided into the sub-low temperature anterograde machine perfusion group (n = 4) and the blank control group (n = 3) using the random number table method. A yorkshire model of brain tissue injury induced by traumatic blood loss was established. Firstly, the perfusion temperature and blood oxygen saturation were monitored in real-time during the perfusion process. The number of red blood cells, hemoglobin content, NA⁺, K⁺, and Ca²⁺ ions concentrations and pH of the perfusate were detected. Following perfusion, we specifically examined the parietal lobe to assess its water content. The prefrontal cortex and hippocampus were then dissected for histological evaluation, allowing us to investigate potential regional differences in tissue injury. The blank control group was sampled directly before perfusion. All statistical analyses and graphs were performed using GraphPad Prism 8.0 Student t-test. All tests were two-sided, and p value of less than 0.05 was considered to indicate statistical significance. RESULTS: The contents of red blood cells and hemoglobin during perfusion were maintained at normal levels but more red blood cells were destroyed 3 h after the perfusion. The blood oxygen saturation of the perfusion group was maintained at 95% - 98%. NA⁺ and K⁺ concentrations were normal most of the time during perfusion but increased significantly at about 4 h. The Ca²⁺ concentration remained within the normal range at each period. Glucose levels were slightly higher than the baseline level. The pH of the perfusion solution was slightly lower at the beginning of perfusion, and then gradually increased to the normal level. The water content of brain tissue in the sub-low and docile perfusion group was 78.95% ± 0.39%, which was significantly higher than that in the control group (75.27% ± 0.55%, t = 10.49, p < 0.001), and the difference was statistically significant. Compared with the blank control group, the structure and morphology of pyramidal neurons in the prefrontal cortex and CA1 region of the hippocampal gyrus were similar, and their integrity was better. The structural integrity of granulosa neurons was destroyed and cell edema increased in the perfusion group compared with the blank control group. Immunofluorescence staining for glail fibrillary acidic protein and Iba1, markers of glial cells, revealed well-preserved cell structures in the perfusion group. While there were indications of abnormal cellular activity, the analysis showed no significant difference in axon thickness or integrity compared to the 1-h blank control group. CONCLUSIONS Mild hypothermic machine perfusion can improve ischemia and hypoxia injury of yorkshire brain tissue caused by traumatic blood loss and delay the necrosis and apoptosis of yorkshire brain tissue by continuous oxygen supply, maintaining ion homeostasis and reducing tissue metabolism level.

PURPOSE: To analyze risk factors for severe trauma and establish a nomogram for early risk prediction, to improve the early identification of severe trauma. METHODS: This study was conducted on the patients treated in 81 trauma treatment institutions in Gansu province from 2020 to 2022. Patients were grouped by year, with 5364 patients from 2020 to 2021 as the training set and 1094 newly admitted patients in 2020 as the external validation set. Based on the injury severity score (ISS), patients in the training set were classified into 2 subgroups of the severe trauma group (n = 478, ISS scores ≥25) and the non-severe trauma group (n = 4886, ISS scores <25). Univariate and binary logistic regression analyses were employed to identify independent risk factors for severe trauma. Subsequently, a predictive model was developed using the R software environment. Furthermore, the model was subjected to internal and external validation via the Hosmer-Lemeshow test and receiver operating characteristic curve analysis. RESULTS: In total, 6458 trauma patients were included in this study. Initially, this study identified several independent risk factors for severe trauma, including multiple traumatic injuries (polytrauma), external hemorrhage, elevated shock index, elevated respiratory rate, decreased peripheral oxygen saturation, and decreased Glasgow coma scale score (all p < 0.05). For internal validation, the area under the receiver operating characteristic curve was 0.914, with the sensitivity and specificity of 88.4% and 87.6%, respectively; while for external validation, the area under the receiver operating characteristic curve was 0.936, with the sensitivity and specificity of 84.6% and 93.7%, respectively. In addition, a good model fitting was observed through the Hosmer-Lemeshow test and calibration curve analysis (p > 0.05). CONCLUSION This study establishes a nomogram for early risk prediction of severe trauma, which is suitable for primary healthcare institutions in underdeveloped western China. It facilitates early triage and quantitative assessment of trauma severity by clinicians prior to clinical interventions.

OBJECTIVES: With the accelerating aging of the population and the rising prevalence of chronic diseases, the number of patients with pressure injuries (PIs) has increased markedly, prolonging the period of disease-related care. Informal caregivers play a critical role in the daily care of patients with pressure injuries, and their care burden has become increasingly prominent. This study aims to investigate the current status and influencing factors of care burden among informal caregivers of patients with PIs, providing evidence for targeted intervention strategies. METHODS: A total of 170 informal caregivers of patients with PIs were selected by convenience sampling from the Third Xiangya Hospital of Central South University. General demographic and clinical data of both patients and caregivers were collected. The Zarit Caregiver Burden Inventory (ZBI), Knowledge-Attitude-Practice Scale for Informal Caregivers of Patients with PIs, General Self-Efficacy Scale (GSES), and Family Caregiver Task Inventory (FCTI) were used to assess caregiving burden, knowledge-attitude-practice level, self-efficacy, and caregiving ability, respectively. Pearson correlation analysis was conducted to evaluate relationships among ZBI, Knowledge-Attitude-Practice Scale for Informal Caregivers of Patients with PIs, GSES, and FCTI scores. Stepwise multiple linear regression analysis was used to identify factors influencing caregiving. RESULTS: Among the 170 patients with pressure injuries, the age was (65.52±15.88) years; 118 (69.41%) were male and 52 (30.59%) were female. The duration of PIs was less than 1 month in 108 (63.53%) cases and 1 to 6 months in 40 cases (23.53%). Stage II injuries were predominant (135 cases, 79.41%). A total of 193 pressure injury sites were recorded, most commonly located at the sacrococcygeal region (127 sites, 65.80%), followed by the head (3 sites, 1.55%), shoulder and back (9 sites, 4.66%), feet (24 sites, 12.44%), and other regions (30 sites, 15.55%). Informal caregivers were 48.82% aged 46 to 59 years, 54.71% female, 41.77% primarily spouses and 47.06% children of the patients, and 77.06% lived with the patients. Caregivers who received assistance from others or had higher family per-capita monthly income reported significantly lower caregiver burden scores than those without assistance or with lower income (all P<0.001). The total ZBI score was 50.89±14.95, indicating a moderate burden. The total scores of the Knowledge-Attitude-Practice Scale for Informal Caregivers, GSES, and FCTI were 50.61±7.22, 26.03±7.11, and 14.76±8.70, respectively. Pearson correlation analysis revealed that ZBI scores were correlated with scores on the Knowledge-Attitude-Practice Scale for Informal Caregivers of Patients with PIs (r=-0.543, P<0.001), GSES scores (r=-0.545, P<0.001), and FCTI scores (r=0.800, P<0.001). The scores on Knowledge-Attitude-Practice Scale for Informal Caregivers of patients with PIs were correlated with GSES scores (r=0.500, P<0.001) and FCTI scores (r=-0.461, P<0.001); GSES scores was negatively correlated with FCTI scores (r=-0.415, P<0.001). Stepwise multiple linear regression analysis showed that assistance availability, family per-capita monthly income, total scores on the Knowledge-Attitude-Practice Scale for Informal Caregivers of Patients with PIs, total GSES score, and total FCTI score were the main influencing factors of caregiver burden, jointly explaining 79.38% of its variance. CONCLUSIONS The main factors influencing the caregiving burden of informal caregivers of patients with PIs include the availability of assistance, family per-capita monthly income, total score on the Knowledge-Attitude-Practice Scale for Informal Caregivers of PI patients, total score on the GSES, and total score on the FCTI. Developing targeted intervention strategies addressing these factors may help alleviate the caregiving burden among informal caregivers of patients with PIs.

This study aims to establish BHK-21 stable cell lines expressing APN from four species(human,pig,dog,and cat),the APN fragments were amplified from pEGFP-C1-APN plasmids of the four species stored in the laboratory to generate the recombinant plasmids pcDNA4.0-APN.Af-ter the recombinant plasmids were transfected into BHK-21 cells,the stable BHK-21 cell lines ex-pressing the APNs were selected by two rounds of limited dilution.The constructed BHK-21 cell lines were identified by indirect immunofluorescence assay(IFA),and their susceptibility to PD-CoV and TGEV was tested for these four cell lines.Virus infection experiments revealed that PD-CoV infected cells expressing human,pig,and dog APNs,while it did not infect cells expressing cat APN.Simultaneously,TGEV infected cells expressing pig,dog,and cat APNs,but did not infect cells expressing human APN.The results suggest that the risk of cross-species infection for different coronaviruses and the established cell line can be used effectively to evaluate the virus in-fection.The findings also revealed that PDCoV has the potential risk of cross-species infection of human and dog,and TGEV has the potential risk of cross-species infection of dog and cat.These results provide a basis for the prevention and control strategy of coronaviruses.

Objective To investigate the clinical efficacy and safety of facilitated percutaneous coronary intervention(PCI)with half-dose recombinant staphylokinase(r-SAK)in patients with ST-segment elevation myocardial infarction(STEMI)who are expected to undergo PCI within 120 minutes.Methods From October 2021 to August 2022,a total of 200 STEMI patients in eight centers were included and randomly assigned in a 1﹕1 ratio to either r-SAK group or control group.Patients received loading doses of aspirin and ticagrelor and intravenous heparin and were randomized to receive an intravenous bolus of either 5 mg r-SAK or normal saline prior to PCI.The outcomes were set as ST-segment resolution(STR)at 60-90 minutes after PCI,the proportion and transition of pathological Q waves on the 5th day after PCI,and the proportion of high-sensitivity cardiac troponin T(hs-cTnT)peaking within 12 hours of onset.The safety outcome was major bleeding events defined as Bleeding Academic Research Consortium(BARC)≥type 3 bleeding during hospitalization.Results Compared with the control group,the r-SAK group had a higher proportion of STR≥70%within 60-90 minutes after PCI(58.3%vs.40.3%,P=0.009);a lower proportion of pathological Q waves(59.1%vs.74.1%,P=0.040);a lower rate of Q wave progression(14.8%vs.43.2%,P＜0.001);a higher rate of Q wave disappearance(12.5%vs.3.7%,P=0.027);and a higher proportion of hs-cTnT peaking within 12 hours of symptom onset[31/40(77.5%)vs.17/33(51.5%),P=0.027].Regarding the safety outcome,no significant difference in BARC≥type 3 bleeding was found between the two groups during hospitalization(P＞0.05).Conclusions For STEMI patients who were expected to undergo primary PCI within 120 minutes of symptom onset,the facilitated PCI with half-dose r-SAK significantly increased the proportion of STR≥70%at 60-90 minutes after PCI,reduced the formation of pathological Q waves,and shortened the time to peak hs-cTnT,without increasing the risk of bleeding,which should be an alternative reperfusion strategy worthy of further study.

Objective To explore the effect of mangiferin(MF)on pyroptosis in an amyotrophic lateral sclerosis(ALS)cell model by regulating the nuclear factor erythroid 2-related factor 2/heme oxygenase-1(Nrf2/HO-1)signaling pathway.Methods(1)Mouse NSC-34 cell lines transfected with hSOD1WT and hSOD1G93A plasmids were randomly divided into blank group,model group,MF(100 μmol/L)group,MF(200 μmol/L)group.MF was added into the culture plate for 24 hours.Cell viability was assessed using CCK-8 kit.Lactate dehydrogenase(LDH)release was measured using LDH cytotoxicity detection kit.Levels of inflammatory factors interleukin(IL)-1β and IL-18 in cell supernatant were determined by enzyme-linked immunosorbent assay(ELISA).The expression of Nrf2,HO-1,NADPH quinone oxidoreductase-1(NQO-1),NOD-like receptor protein 3(NLRP3),gasdermin D(GSDMD)-N and caspase-1 was detected by Western blotting.(2)Mouse hSOD1G93A NSC-34 cells were randomly divided into model group,MF(200 μmol/L)group,Nrf2-siRNA group and Nrf2-siRNA+MF(200 μmol/L)group.The cells were transiently transfected with Nrf2-siRNA using LipofectamineTM 3000.Western blotting was used to detect the protein expression levels of Nrf2,HO-1,NQO-1,NLRP3,caspase-1 and GSDMD-N.Results(1)The results of the CCK-8 assay showed that after the hSOD1G93A NSC-34 cells were treated with MF at concentrations of 300 μmol/L and below for 24 hours,the changes in cell viability were not significant(P>0.05).Compared with blank group,the release of LDH,the contents of IL-1β and IL-18 in the cell culture supernatant of model group were increased(P<0.001);the protein expression levels of Nrf2,HO-1,and NQO-1 were decreased(P<0.05 or P<0.01);the protein expression levels of NLRP3,caspase-1,and GSDMD-N were increased(P<0.05 or P<0.01 or P<0.001).Compared with model group,the release of LDH,the contents of IL-18 and IL-1β in the culture supernatant in MF(100 μmol/L)and MF(200 μmol/L)groups were decreased(P<0.001);the protein expression levels of NLRP3,caspase-1 and GSDMD-N were decreased(P<0.05 or P<0.001),and the expression levels of Nrf2,HO-1 and NQO-1 were increased(P<0.05 or P<0.01).(2)Compared with model group,the protein expession levels of Nrf2,NO-1 and NQO-1 were increased(P<0.05 or P<0.001)in MF(200 μmol/L)group,while the protein expression levels of NLRP3,caspase-1 and GSDMD-N were decreased(P<0.001);the protein expression levels of Nrf2 and HO-1 were decreased in Nrf2-siRNA group(P<0.01 or P<0.001),while the protein expression levels of NLRP3,caspase-1 and GSDMD-N were increased(P<0.001).Compared with Nrf2-siRNA group,the protein expression levels of Nrf2,HO-1 and NQO-1 in Nrf2-siRNA+MF(200 μmol/L)group were increased(P<0.01 or P<0.001),and the protein expression levels of NLRP3,caspase-1 and GSDMD-N were decreased(P<0.001).Conclusion MF can inhibit pyroptosis in the ALS cell model through Nrf2/HO-1 signaling pathway,playing a protective role.
