OBJECTIVE To investigate the therapeutic effect and mechanism of Qiwei dongqingye powder （QDP） on bronchial asthma in mice. METHODS The mice were divided into blank group （normal saline）， model group （normal saline）， dexamethasone group （2 mg/kg）， and QDP low-， medium-， and high-dose groups （200， 400， 800 mg/kg）， with 14 mice in each group. Except for the blank group， mice in all other groups were given ovalbumin via intraperitoneal injection followed by aerosol inhalation to induce a bronchial asthma model. During the modeling process， mice in each group were administered corresponding drug solutions or normal saline intragastrically/intraperitoneally. After the last medication， the number of cells in the bronchoalveolar lavage fluid （BALF） of the mice was observed and counted； the pathological changes of the bronchus and lung tissue were observed； the levels of malondialdehyde （MDA）， nitric oxide （NO）， total superoxide dismutase （T-SOD）， and glutathione peroxidase （GSH-Px） in the lung tissue of the mice were determined， and the level of interleukin-17 （IL-17） in the BALF and serum was determined. Transcriptomics was employed to predict and validate the mechanism of action of QDP against bronchial asthma. RESULTS Compared with the model group， the total cell count， neutrophil count， lymphocyte count， and macrophage counts in the BALF of the QDP high-dose group were all significantly reduced （ P ＜0.05）； the levels of MDA and NO in the lung tissue， and the levels of IL-17 in the BALF and serum were all decreased significantly （ P ＜0.05）； the levels of T-SOD and GSH-Px were significantly increased （ P ＜0.05）； the arrangement of lung tissue cells tended to normalize， with reduced infiltration of inflammatory cells and decreased exfoliation of bronchial simple columnar epithelial cells. The transcriptomic results revealed that the differentially expressed genes were B-cell receptor signaling pathway， nuclear factor κB （NF-κB） signaling pathway， ferroptosis signaling pathway， and others. Further validation revealed that， compared with the model group， the expression levels of NF-κB p65 and chemokine ligand 20， as well as the phosphorylation level of NF-κB inhibitor protein α， were significantly decreased in the lung tissues of the mice in all QDP groups （ P ＜0.05）. Conversely， the protein expression of nuclear factor erythroid 2-related factor 2 （Nrf2） and heme oxygenase 1 （HO-1） were significantly increased （ P ＜0.05）. CONCLUSIONS QDP can effectively alleviate bronchial asthma by inhibiting the NF-κB signaling pathway， activating the Nrf2/HO-1 signaling pathway， regulating oxidative stress， and reducing inflammatory responses.

ObjectiveThis paper aims to explore the in vitro anti-psoriasis activity and potential mechanism of Kangfuxin liquid （KFX liquid）， providing experimental evidence for the anti-psoriasis effect of KFX liquid. MethodsFirstly， the uninduced human immortalized keratinocyte cells （HaCaT cells） were divided into seven groups， namely the control group and KFX liquid groups with different doses （5， 10， 20， 40， 80， 160 g·L^-1）. After being treated with different concentrations of KFX liquid， the effect of KFX liquid on the normal cell proliferation was detected by using the cell counting kit-8 （CCK-8） method. Secondly， the uninduced HaCaT cells were divided into six groups， namely the control group and recombinant human interleukin-7A （rh-IL-7A） groups with different doses （5， 10， 50， 100， 120 g·L^-1）. After being treated with different concentrations of recombinant human interleukin-17A （rh IL-17A） liquid， the effect of rh IL-17A on cell proliferation was detected. The optimal induction concentration was screened. Then， normal HaCaT cells were divided into a control group and KFX liquid groups with different doses （5， 10， 20， 40， 80， 160 g·L^-1）. Except for the control group， the other groups established psoriasis cell models with the optimal induction concentration of rh IL-17A. After being treated with different concentrations of KFX liquid， the effects of KFX liquid on the psoriasis-like HaCaT cell proliferation were investigated. Finally， the uninduced HaCaT cells were divided into six groups， namely the control group， rh IL-17A group， methotrexate （MTX） group， and KFX liquid groups with different doses （20， 40， 80 g·L^-1）. Except for the control group， the other groups used the optimal induction concentration of rh IL-17A to establish psoriasis cell models. After being treated with different drugs， the cell migration levels were detected through scratch assays， and real-time quantitative polymerase chain reaction （Real-time PCR） was used to detect the relative mRNA expression levels of Ki-67 antigen （Ki67）， S100 calcium-binding protein A7 （S100A7）， S100 calcium-binding protein A8 （S100A8）， and S100 calcium-binding protein A9 （S100A9）， thereby comprehensively evaluating the in vitro anti-psoriasis activity of KFX liquid. By detecting the relative mRNA expression levels of interleukin-1β （IL-1β）， interleukin-6 （IL-6）， and chemokine-20 （CXCL-20） inflammatory-related factors in psoriasis-like HaCaT cells and the protein expression levels of Janus kinase 3 （JAK3）， phosphorylated Janus kinase 3 （p-JAK3）， signal transducer and activator of transcription 3 （STAT3）， and phosphorylated signal transducer and activator of transcription 3 （p-STAT3）， the mechanism was explored. ResultsCompared with that of control group， when treated with 80 g·L^-1 KFX liquid for 72 h （P<0.05） and at different times with 160 g·L^-1 KFX liquid， the HaCaT cell proliferation activity was significantly affected （P<0.01）， while the other concentrations of KFX liquid had no significant differences in cell morphology and cell proliferation activity at different times， indicating that the KFX liquid is relatively safe for HaCaT cells and has no obvious toxic side effects. Compared with that of control group， when treated with different concentrations of rh IL-17A for 24 h， the HaCaT cell proliferation activity was significantly enhanced， and the cell activity was the strongest when the concentration was 100 μg·L^-1 （P<0.05）， with a density close to 100% and intact cell morphology， indicating that 100 μg·L^-1 is the optimal concentration for inducing HaCaT cell proliferation. The results of the KFX liquid treatment on rh IL-17A-induced psoriasis-like cells show that the KFX liquid not only effectively inhibits the rh IL-17A-induced psoriasis-like HaCaT cell proliferation activity （P<0.01）， but also significantly reduces the migration ability of rh IL-17A-induced psoriasis-like HaCaT cells （P<0.01）， and the relative mRNA expression levels of Ki67， S100A7， S100A8， and S100A9 （P<0.01）. Moreover， the KFX liquid can significantly reduce the relative mRNA expression levels of IL-1β， IL-6， and CXCL-20 in rh IL-17A-induced psoriasis-like cells （P<0.01）， and significantly inhibit the phosphorylation levels of JAK3 and STAT3 proteins （P<0.05， P<0.01）. ConclusionThe KFX liquid has no obvious toxicity to uninduced HaCaT cells. It can inhibit rh IL-17A-induced psoriasis-like HaCaT cell proliferation， reduce the cell migration ability， and has good in vitro anti-psoriasis activity. Its action mechanism may be related to downregulating the expression levels of inflammation-related cytokines in the JAK3/STAT3 signaling pathway and inhibiting the phosphorylation levels of JAK3 and STAT3 proteins.

Objective To study the correlation of cognitive dysfunction with autonomic nerve function damage in patients with cerebral small vessel disease (CSVD). Methods A total of 310 patients with CSVD admitted from June 2022 to June 2025 were included. Montreal Cognitive Assessment Scale (MoCA) was applied for cognitive function assessment, and Scale for Outcomes in PD for Autonomic Symptoms (SCOPA-AUT) was used to evaluate autonomic nerve function damage. The incidence rate of autonomic nerve function damage, total score and dimensions scores of SCOPA-AUT were counted. According to the presence or absence of autonomic nerve function damage, the enrolled patients were categorized into damage group and non-damage group. The total score of MoCA and scores of dimensions were compared between both groups. Pearson correlation analysis model was utilized to analyze the correlation between total score of MoCA and scores of dimensions of SCOPA-AUT in patients with CSVD. Results Among the 310 patients, 63.87% cases (198 / 310) had autonomic nerve function damage. The SCOPA-AUT total score and scores of dimensions of gastrointestinal function, urinary system function, cardiovascular function, body temperature regulation, pupil movement and sexual function were (34.16 ± 10.41) points, (10.25 ± 3.31) points, (9.44 ± 2.89) points, (4.02 ± 1.66) points, (6.41 ± 2.35) points, (1.35 ± 0.49) points and (2.69 ± 0.81) points. The total score of MoCA and scores of language function, naming, delayed recall and attention in the damage group were lower than those in the non-damage group (P < 0.05). Pearson correlation analysis results revealed that the total score, urinary system score, cardiovascular function score and body temperature regulation score of SCOPA-AUT were negatively correlated with the total score of MoCA (r = -0.545, -0.598, -0.607, -0.615, P < 0.05), and the gastrointestinal function score, pupil movement score and sexual function score were not significantly associated with total score of MoCA (P > 0.05). Conclusion The risk of autonomic nerve function damage is high in patients with CSVD, and it involves multiple systems and is closely related to the cognitive function of patients.

ObjectiveTo investigate the association between albumin （Alb） and recompensation by comparing recompensation rate between hepatitis B/C virus-related decompensated liver cirrhosis patients with different Alb levels， and to provide guidance for the identification and management of high-risk patients in clinical practice. MethodsRelated clinical data were collected from 734 patients with hepatitis B/C virus-related decompensated liver cirrhosis who attended The Third People’s Hospital of Kunming from January 1， 2016 to December 31， 2022， and they were divided into three groups based on the level of Alb. The linear regression analysis and chi-square test were used for trend tests. The Kaplan-Meier curve was plotted for the cumulative incidence rate of recompensation in the three groups， and the log-rank test was used for comparison between groups. A Cox proportional-hazards regression model analysis was used to investigate the association between Alb and recompensation in patients with hepatitis B/C virus-related decompensated liver cirrhosis. ResultsAmong the 734 patients with hepatitis B/C virus-related decompensated liver cirrhosis， 270 achieved recompensation， with a recompensation rate of 36.8%. All patients had a median Alb level of 29.90 （25.90 — 34.80） g/L on admission， and according to the level of Alb， they were divided into <25.9 g/L group with 177 patients， 25.9 — 34.8 g/L group with 377 patients， and >34.8 g/L group with 180 patients； 36 patients （20.3%） in the <25.9 g/L group， 138 （36.6%） in the 25.9 — 34.8 g/L group， and 96 （53.3%） in the >34.8 g/L group achieved recompensation， and the recompensation rate increased with the increase in Alb level （χ²=41.730， P<0.001）. After adjustment for all confounding factors， compared with the <25.9 g/L group， there was a significant increase in the incidence rate of recompensation in the 25.9 — 34.8 g/L group （hazard ratio ［HR］=1.842， 95% confidence interval ［CI］： 1.274 — 2.663） and the >34.8 g/L group （HR=2.336， 95% CI： 1.575 — 3.463）. The Kaplan-Meier survival analysis showed that there was a significant difference in the cumulative incidence rate of recompensation between the three groups （χ²=41.632， P<0.001）. ConclusionAlb level is an influencing factor for recompensation in patients with hepatitis B/C virus-related decompensated liver cirrhosis， and the recompensation rate increases with the increase in Alb level.

A retrospective analysis was conducted on a case of recurrence during pregnancy of early-stage endometrial cancer (EEC) after fertility-preserving treatment, and literature review was conducted. The patient underwent two cycles of controlled ovarian stimulation and three cycles of frozen-thawed embryo transfer after fertility-preserving treatment, early abortion after the third transfer and meanwhile the recurrence of endometrial cancer was found. Fertility-preserving retreatment was given after multidisciplinary discussion based on the patient's fertility intention, ultrasound, pelvic magnetic resonance imaging and other examinations. After complete remission, the remaining cryopreserved embryos of the patient were tested for euploidy by preimplantation genetic testing, and the euploid embryo was transferred and delivered at term successfully. Fertility-preserving treatment for patients with EEC need comprehensive management to reduce the recurrence rate. Recurrent patients can choose fertility-preserving retreatment under a comprehensive evaluation.

Objective To explore the effect of exercise under cold exposure on hepatic protein ki-nase B(AKT)/forkhead box O1(FoxO1)expression in obese rats.Methods Among rats successfully induced nutritional obesity by high-fat diet,forty were selected and randomly divided into a normal-temperature control group(NC,n=10),a normal-temperature exercise group(NE,n=10),a sus-tained-cold control group(SC,n=10),and a sustained-cold exercise group(SE,n=10).The normal temperature was kept at 25°C±1°C,while the low temperature remained at 4°C±1°C,with 50%to 60%relative humidity.The exercise protocol was every other day at a speed of 25 m/min for 2 sets of 30 min each,with an interval of 10 minutes.After 5 weeks,glucose and insulin tolerance were tested by oral glucose tolerance test(OGTT)and insulin tolerance test insulin tolerance test(ITT).Then,all rats were weighed and sacrificed,then taken blood from the abdominal aorta to sepa-rate serum,followed by detection of serum alanine aminotransferase(ALT)and aspartate aminotransfer-ase(AST)levels using fully automatic biochemical analyzer.Moreover,livers were weighed to calcu-late the liver index.Meanwhile,the mRNA expressions of hepatic AKT,FoxO1 and PEPCK were de-tected using RT-qPCR,while the protein expressions of AKT,phosphorylated protein kinase B(p-AKT),and FoxO1 in the liver were measured using Western blotting.Results(1)The average body weights of the NE,SC and SE groups were significantly lower than the NC group(P<0.01),with that of the SC and SE groups significantly lower than the NE group(P<0.01).(2)Compared with the NC group,the area under the OGTT curve of the SC group decreased(P<0.01).Moreover,the area under the ITT curve of the SE group was significantly lower than the other 3 groups(P<0.01,P<0.01,P<0.05),with that of the NE and SC groups significantly lower than the NC group(P<0.05,P<0.01).(3)The liver indices of the NE,SC and SE groups were all significantly lower than the NC group(P<0.01),while the serum ALT level of the NE group was significantly lower than the NC and SE groups(P<0.05),with that of the SC group significantly lower than the NC group(P<0.01).(4)Compared with the NC group,hepatic AKT mRNA expression increased significantly in the SE group(P<0.05),while the hepatic FoxO1 and PEPCK mRNA expression decreased significantly in the other three groups(P<0.01).(5)Compared with the NC group,the liver AKT protein phosphorylation levels were significantly higher in the other three groups(P<0.05,P<0.05,P<0.01),while the FoxO1 protein expression decreased significantly(P<0.05,P<0.01,P<0.01).(6)Body mass,liver FoxO1,PEPCK mRNA expression,AKT protein phosphorylation level and FoxO1 protein expression level of obese rats were affected by cold exposure,exercise and cold exposure+exercise,and the liver index and serum ALT level were done by exercise and cold exposure+exercise.However,the area un-der the ITT curve and liver AKT mRNA content were impacted by cold exposure and exercise,while that under the OGTT curve was influenced by cold exposure and cold exposure+exercise.Conclu-sion Exercise under cold exposure can activate hepatic AKT/FoxO1 signaling pathway,protect liver function,increase insulin sensitivity,and effectively improve glucose metabolism in obese rats.

Anhedonia is one of the core features of major depressive disorder (MDD) and is associated with poor functional outcomes in MDD patients. Psychosocial functional recovery is an important goal for achieving MDD remission. Although longitudinal studies have found association between anhedonia and impaired psychosocial function, there is still a lack of neurobiological biomarkers that can indicate this relationship. In this review, brain structural and functional changes associated with anhedonia and impaired psychosocial function in MDD patients are reviewed from the perspective of magnetic resonance imaging. It finds that anhedonia and psychosocial dysfunction in MDD may share common neuroimaging changes, manifested in abnormal brain regions such as the nucleus accumbens, caudate nucleus, putamen nucleus, orbitofrontal cortex, insula, amygdala, anterior cingulate cortex, dorsolateral prefrontal cortex, superior parietal lobe, inferior frontal gyrus and temporal lobe. These findings help to better understand the pathophysiology of the disease and offer potential insights for developing new treatment strategies.

Objective:To investigate the occurrence of work-related musculoskeletal disorders (WMSDs) in bus drivers in Zhuhai City, analyze the ergonomic factors, and explore the prevention and control measures of WMSDs.Methods:From March to May 2023, 1675 active bus drivers from 5 branches of a bus group in Zhuhai were selected by stratified sampling method. The incidence of WMSDs among bus drivers in the past 12 months was investigated by using the modified Chinese Version of Musculoskeletal Disorders Questionnaire. The influencing factors of WMSDs were analyzed by χ2 test and generalized linear model. Results:The total incidence of WMSDs in bus drivers in the past 12 months was 47.2% (790/1675) , and the incidence of WMSDs in neck and shoulder and lower back was 36.9% (618/1675) and 31.7% (531/1675) , respectively. The χ2 test showed that there were statistically significant differences in the incidence of WMSDs among bus drivers with different individual factors such as body mass index (BMI) , physical exercise and looking down at mobile phones ( P<0.05) . There were significant differences in the incidence of WMSDs in the neck and shoulder of bus drivers with different years of service and number of stops on their routes ( P<0.05) . There were statistically significant differences in the incidence of WMSDs in the lower back of bus drivers with different one-way driving time, shift patterns, and rest breaks during work ( P<0.05) . Abnormal BMI, professional working years >12 years, uncomfortable working posture, frequent turning, slightly forward neck posture, large forward neck posture and long shoulder posture were the risk factors for WMSDs of bus drivers ( P<0.05) , and comfortable seat was the protective factor ( P<0.05) . One-way driving time >70 min, shift work schedules, uncomfortable working posture, slightly forward back posture, and frequent turning were the risk factors leading to lower back WMSDs ( P<0.05) , and physical exercise, comfortable driving cabin space, and seat comfort were the protective factors ( P<0.05) . Conclusion:The total incidence of WMSDs in bus drivers is higher, and ergonomic factors are related to the occurrence of WMSDs. In the implementation of bus driving space comfort, human-computer interaction interface friendliness and seat comfort, employers should be reasonable allocation of fitness facilities, regular training, reasonable shift organization and other measures to prevent and control the occurrence of bus drivers WMSDs.

Photoacoustic imaging (PAI), an emerging hybrid imaging modality, integrates the high spatial resolution of optical imaging with the deep-tissue imaging capability of ultrasound. Emerging evidence from recent studies in dental medicine has demonstrated the unique potential of PAI in screening, diagnosis, and therapeutic monitoring of oral pathologies, including periodontal diseases, oral cancers, and pulpal disorders. However, its clinical translation remains contingent upon addressing multiple technical barriers, particularly signal attenuation induced by optical scattering in biological tissues and limitations in real-time imaging efficiency. Therefore, investigating the advancements and challenges of PAI technology in the diagnosis of oral diseases will contribute to advancing further research and clinical applications, thereby providing practical support for improving the accuracy of early diagnosis and the efficacy of treatment for oral diseases.
