ObjectiveTo explore the current situation and influencing factors of humanistic care experience among patients visiting traditional Chinese medicine （TCM） outpatient clinics in China， and to provide a basis for optimizing TCM-characterized services in both TCM and Western medicine hospitals. MethodsA multi-center cross-sectional study was conducted using convenience sampling to select 35 hospitals across 13 provinces in China （including 3 TCM hospitals and 32 TCM outpatient clinics in general hospitals）. A total of 3，430 patients were surveyed using the general information questionnaire and the Outpatient Humanistic Care Experience Questionnaire， with data collected via Questionnaire Star. Univariate analysis and multiple linear regression were employed to examine the impacts of patient characteristics， visit characteristics， hospital type （TCM hospital/general hospital）， and geographic region （eastern/central/western） on humanistic care experience. ResultsThe total score of humanistic care experience was 194 （188， 233）. Univariate analysis showed that gender， educational level， current residence， per capita monthly household income， location attribute of medical institutions， number of previous visits to this hospital， payment method of medical expenses， previous hospitalization history in this hospital， frequency of outpatient visits within the past 12 months， self-rated disease severity， familiarity with the outpatient procedures， implementation of the follow-up service provided by the hospital， satisfaction with follow-up services， the grade of the hospital visited， geographical region of the hospital visited， and the department visited had an impact on the humanistic care experience during outpatient visits （P<0.05）. Multivariate analysis demonstrated that educational level （β=0.609， P=0.011）， self-rated disease severity （β=-0.646， P=0.047）， familiarity with outpatient procedures （β=4.784， P<0.001）， satisfaction with follow-up services （β=6.365， P<0.001）， and the grade of the hospital visited （β=-5.487， P<0.001） affected the humanistic care experience in outpatient medical treatment， explaining 24.4% of the total variation. ConclusionHumanistic care experience in TCM outpatient clinics is influenced by multiple factors. It is recommended to optimize the medical treatment process， strengthen doctor-patient communication training， and establish a precise follow-up mechanism， with a focus on improving care perceptions among patients with lower education levels and those attending primary-level hospitals， to refine the TCM-characterized service system.

Obesity is a significant risk factor for cancer and is associated with breast cancer metastasis. Nevertheless, the mechanism by which alterations in systemic metabolism affect tumor microenvironment (TME) and consequently influence tumor metastasis remains inadequately understood. Herein, we found that perturbations in circulating metabolites induced by obesity promote metastasis-like phenotypes in breast cancer. Oleoylcarnitine (OLCarn) concentrations were elevated in the serum of obese mice and humans. Administration of exogenous OLCarn induces metastasis-like characteristics in breast cancer cells. Mechanistically, OLCarn directly interacts with the Arg176 site of adenylate cyclase 10 (ADCY10), leading to the activation of ADCY10 and enhancement of cAMP production. Mutations at Arg176 prevent OLCarn from binding to ADCY10, disrupting the ADCY10-mediated activation of cyclic adenosine monophosphate (cAMP) signaling pathway. This activation promotes transcription factor 4 (TCF4)-dependent kinesin family member C1 (KIFC1) transcription, thereby driving breast cancer metastasis. Conversely, the neutralization of both ADCY10 and KIFC1 through knockdown or pharmacological inhibition abrogates the oncogenic effects mediated by OLCarn. Hence, obesity-induced systemic environmental changes lead to the aberrant accumulation of OLCarn within the TME, making it a potential therapeutic target and biomarker for breast cancer.

OBJECTIVE To investigate the intervention effect of Dabufei decoction on acute lung injury in rats with high altitude hypoxia by regulating the expression of the HIF-1α/NLRP3 signaling pathway and related molecules. METHODS Sixty SPF SD rats were randomly divided into blank group, model group, positive drug group, Dabufei decoction high-dose, medium-dose, and low-dose groups with 10 rats in each group. After 3 d of adaptation to feeding, the rats in the blank group and model group were given the same amount of normal saline by gavage, and the rats in Dabufei decoction high-dose, medium-dose, and low-dose groups were given gavage for 14 d, respectively. The positive drug group was given dexamethasone by intraperitoneal injection for three consecutive days before entering the chamber. Except for the blank group, the rats in each group were exposed to hypoxia in the experimental animal low-pressure simulation chamber from the 15th day for three consecutive days. At the end of the experiment, the wet to dry ratio(W/D) of the rat lung tissue was detected. The morphology of lung tissue was observed by HE staining. ELISA detected the levels of IL-1β and IL-18 in serum. Western blotting and RT-qPCR were used to detect the protein and mRNA expressions of HIF-1α, NLRP3, GSDMD, and caspase-1 in the lung tissue of rats. RESULTS The W/D value showed that compared with the blank group, the W/D of the model group was significantly increased(P<0.01). Compared with the model group, the W/D of rats in the positive drug group, Dabufei decoction high-dose group, medium-dose, and low-dose groups was significantly decreased(P<0.01 or P<0.05). HE results showed that compared with the blank group, alveolar septum thickening, pulmonary interstitial congestion, edema, inflammatory cell infiltration, and a small amount of exudation in the alveolar cavity were seen in the lung tissue of the model group. Compared with the model group, the thickening of alveolar walls in the positive drug group, Dabufei decoction high-dose group, medium-dose, and low-dose groups were reduced, and the pulmonary interstitial congestion, edema, and inflammatory cell infiltration were significantly reduced. ELISA results showed that IL-1β and IL-18 in rat serum were significantly higher in the model group than in the blank group(P<0.01). Compared with the model group, the levels of IL-1β and IL-18 in the serum of the rats in the positive drug group, Dabufei decoction high-dose group, medium-dose, and low-dose groups were significantly decreased(P<0.05 or P<0.01). Moreover, the results of Western blotting and RT-qPCR showed that compared with the blank group, the relative protein and mRNA expressions of HIF-1α, NLRP3, GSDMD, and caspase-1 in the lung tissue of the model group were significantly increased(P<0.01). Compared with the model group, the relative protein and mRNA of HIF-1α, NLRP3, caspase-1 and GSDMD in the positive drug group and Dabufei decoction high-dose group were significantly decreased(P<0.05 or P<0.01), the relative protein of HIF-1α, NLRP3, caspase-1 and GSDMD in Dabufei decoction medium-dose group were significantly decreased and HIF-1α, caspase-1 mRNA were significantly decreased(P<0.05), the relative protein of HIF-1α and GSDMD in the low-dose group was decreased(P<0.05). The positive drug group and Dabufei decoction high-dose group had the more significant effect. CONCLUSION Dabufei decoction can regulate the HIF-1α/NLRP3 signaling pathway, inhibit pyroptosis and reduce inflammation, and has a certain protective effect on acute lung injury in rats with high altitude hypoxia.

ObjectiveTo investigate the effects of licoflavone A on the proliferation and glycolysis of gastric cancer cells in the hypoxic environment. MethodHuman gastric cancer AGS cells were classified into five groups： Normoxia， hypoxia， and low-， medium-， and high-dose （25， 50， 100 μmol·L^-1， respectively） licoflavone A. The cells in other groups except the normoxia group were cultured in the environment with 5% O₂ for 48 h. The cell counting kit-8 （CCK-8） and colony formation assay were employed to examine the proliferation of AGS cells. Cell migration was detected by the scratch assay. The protein and mRNA levels of hypoxia-inducible factor 1-alpha （HIF-1α）， glucose transporter 1 （GLUT1）， lactate dehydrogenase A （LDHA）， pyruvate kinase M2 （PKM2）， and hexokinase Ⅱ （HK2） in AGS cells were measured by Western blotting and real-time quantitative polymerase chain reaction （Real-time PCR）， respectively. The corresponding kits were used to determine glucose uptake and HK activity. ResultThe CCK-8 results showed that compared with the hypoxia group， the high- and medium-dose licoflavone A groups showed decreased proliferation rate of AGS cells at the time point of 24 h （P<0.01） and all the licoflavone A groups demonstrated decreased proliferation rate at the time point of 48 h （P<0.01）. Compared with the normoxia group， the hypoxia group showed increased number of clone formation of AGS cells （P<0.01）， which was decreased after the treatment with licoflavone A at high， medium， and low doses （P<0.01）. Compared with the normoxia group， the hypoxia group showed increased migration of AGS cells （P<0.01）， which was attenuated by the high， medium， and low doses of licoflavone A （P<0.01）. Compared with the normoxia group， the hypoxia group showed up-regulated mRNA levels of GLUT1， LDHA， PKM2， and HK2 （P<0.05， P<0.01）. Compared with those in the hypoxia group， the mRNA levels of GLUT1， LDHA， PKM2， and HK2 in the high-dose licoflavone A group， GLUT1， LDHA， and HK2 in the medium-dose licoflavone A group， and HK2 in the low-dose licoflavone A group were down-regulated （P<0.05， P<0.01）. The protein levels of HIF-1α， GLUT1， LDHA， PKM2， and HK2 in the hypoxia group were higher than those in the normoxia group （P<0.05， P<0.01）. Compared with those in the hypoxia group， the protein levels of HIF-1α， GLUT1， LDHA， PKM2， and HK2 in the high-dose licoflavone A group and HK2 in the medium- and low-dose licoflavone A groups were down-regulated （P<0.05， P<0.01）. The glucose uptake and HK activity were elevated in the hypoxia group compared with those in the normoxia group （P<0.01）. Compared with the hypoxia group， high-dose licoflavone A decreased the glucose uptake and HK activity， and medium-dose licoflavone A decreased the HK activity （P<0.01）. ConclusionLicoflavone A inhibits the proliferation of AGS cells under hypoxic conditions by regulating glycolysis in gastric cancer.

To analyze the biological characteristics of Pasteurella multocida in bovine respiratory tract and its prevalence in large-scale cattle farms,bacterial isolation,culture,and morphological observation were conducted on the lungs and liver samples of dead cows suffering from respiratory diseases in Hohhot,Inner Mongolia.The isolated strains were studied through biochemical testing,16S rRNA gene sequencing,specific primer PCR identification,capsule serotyping,pathogenicity testing,virulence gene testing,drug sensitivity testing,and drug resistance gene detection methods.The results showed that six strains of Pasteurella multocida serotype A were isolated and identi-fied from the lungs of diseased and dead cows.After sequencing the 16S rRNA sequence of the bac-teria,it was found that the six strains of Pasteurella multocida had the closest genetic relationship with the Chongqing isolate CQ2(CP033599.1).The results of mouse pathogenicity test and viru-lence gene detection showed that all isolates were pathogenic and carried at least 16 or more related virulence genes such as exbB,nanB,sodC,oma 87,etc.,but no hsf1 and toxA were detected.The results of drug sensitivity tests and resistance gene detection showed that the isolated strains were sensitive to different degrees of antibiotics such as ciprofloxacin,ofloxacin,and cefotaxime.They were resistant to streptomycin,clindamycin,and lincomycin,and resistance genes of str A,strB,and tet(H)were detected.The results indicate that there is a certain correlation between the pathoge-nicity and virulence genes,drug resistance phenotype,and drug resistance genes of Pasteurellamultocida type A in cattle.It is recommended to use quinolones(such as ciprofloxacin)and cepha-losporins(such as cefotaxime)antibacterial drugs in clinical practice,which can provide scientific basis and prevention and control plans for the prevention and treatment of respiratory diseases caused by Pasteurella multocida in cattle farms,and lay a foundation for the epidemiological mo-nitoring of bovine respiratory multocida pasteurellosis.

Objective:This study aimed to develop a rapid and accurate integrated nucleic acid detection method tailored for the influenza virus.Methods:We designed primers and probes targeting the predominant influenza virus strains circulating in China in recent years. These were integrated with extraction and amplification reagents and a point of care testing (POCT) system to facilitate a seamless and expedited process involving nucleic acid extraction, reaction system preparation, amplification, and result interpretation for the influenza virus. The specificity of the POCT system was evaluated using cultured influenza viruses, while its cross-reactivity was assessed against common respiratory pathogens, including adenovirus and respiratory syncytial virus.Results:Our study successfully developed duplex amplification primers and probes for both influenza A and B viruses, achieving a detection threshold as low as 500 copies/ml. Specificity tests confirmed that the detection reagents did not show cross-reactivity with other respiratory pathogens such as adenovirus and respiratory syncytial virus. The POCT-based rapid nucleic acid detection method for influenza virus was established, it is capable of completing the entire process from nucleic acid extraction to amplification and result interpretation within 50 minutes, while enabling real-time data upload.Conclusions:The POCT-based rapid influenza virus detection kit developed in this study offers a " sample in, results out" convenience, making it suitable for rapid influenza virus detection in primary care settings. This innovation has significant potential for clinical application.

ObjectiveTo investigate the protective effect of Guiqi Baizhu prescription combined with oxaliplatin on the intestinal barrier of tumor-bearing mice with gastric cancer by regulating downstream aquaporin 3 （AQP3） and aquaporin 4 （AQP4） through the vasoactive intestinal peptide （VIP）/cyclic adenosine monophosphate （cAMP）/protein kinase A （PKA） signaling pathway. MethodThe gastric cancer cell lines MFC with a density of 1×10⁷/mL were prepared into cell suspension. The tumor-bearing mouse model of gastric cancer was established by inoculating 0.2 mL cell suspension under the right axilla of mice. After successful modeling， mice were randomly divided into 5 groups， namely， model group， oxaliplatin group （10 mg·kg^-1）， and high， medium， and low-dose oxaliplatin + Guiqi Baizhu prescription groups （17.68， 8.84， 4.42 g·kg^-1）， with 10 mice in each group， and the remaining 10 mice were set as a blank group. Mice in each group were treated with Chinese medicine， oxaliplatin， or normal saline by gavage or intraperitoneal injection for 14 d. The next day after the last dose， blood was taken from the eyeball to separate serum and take colonic samples. Hematoxylin-eosin （HE） staining was used to observe the changes in tissue morphology. The content of D-lactate acid （D-LA） and diamine oxidase （DAO） in the serum was determined by enzyme-linked immunosorbent assay （ELISA）. The mRNA and protein expressions of VIP， cAMP， PKA， AQP3， and AQP4 were detected by Real-time quantitative polymerase chain reaction （Real-time PCR） and Western blot， respectively. ResultCompared with the blank group， the model group showed edema in the colonic submucosa， disordered arrangement of intestinal glands in the mucosal layer， loss of goblet cells， infiltration of inflammatory cells， and villus shedding. However， there were different degrees of improvement in each administration group. As compared with the blank group， the serum levels of DAO and D-LA in the model group were significantly increased （P<0.01）. As compared with the model group， the levels of DAO and D-LA in the high-dose oxaliplatin + Guiqi Baizhu prescription group and the level of D-LA in the medium-dose oxaliplatin + Guiqi Baizhu prescription group were decreased （P<0.05， P<0.01）. As compared with the oxaliplatin group， the levels of D-LA in the high and medium-dose oxaliplatin + Guiqi Baizhu prescription groups were decreased （P<0.05）， and the levels of DAO and D-LA in other administration groups were decreased as well， but the difference had no statistical significance. As compared with the blank group， the mRNA and protein expression levels of VIP， cAMP， PKA， AQP3， and AQP4 in the model group were significantly decreased （P<0.05， P<0.01）. As compared with the model group， the mRNA and protein expression levels of VIP， cAMP， PKA， AQP3， and AQP4 in each administration group were increased， and those in the high-dose oxaliplatin + Guiqi Baizhu prescription group were significantly increased （P<0.05， P<0.01）， while the protein expression level of cAMP in the medium-dose oxaliplatin + Guiqi Baizhu prescription group were increased （P<0.05）. As compared with the oxaliplatin group， the protein expression levels of cAMP in the high-dose oxaliplatin + Guiqi Baizhu prescription group were increased （P<0.05）， and the mRNA and protein expressions of these indexes in the other groups were also increased but the differences were not statistically significant. ConclusionGuiqi Baizhu prescription combined with oxaliplatin can regulate AQP3 and AQP4 through the VIP/cAMP/PKA signaling pathway to protect the intestinal barrier of tumor-bearing mice with gastric cancer.
