The doctor-patient relationship is a set of social relationships based on shared interests， mutual trust， and emotional bonds， to relieve illnesses and promote health. However， the doctor-patient relationship often falls into tensions and conflicts. How to build a trusting and harmonious doctor-patient destiny community has become one of the most important issues of concern to the whole society. Based on the biopsychosocial concept of disease， the emotion management technique （EMT） emphasizes that doctors take the patient’s emotion as a clue in clinical diagnosis and treatment， regard emotions as one of the important indicators for disease diagnosis， understand the emotional events behind the disease， and provide patients with appropriate empathy and emotional management， so as to provide clinical methods for managing diseases and building a trusting and harmonious doctor-patient relationship.

BACKGROUND:Bone relies on the close connection between blood vessels and bone cells to maintain its integrity.Bones are in a physiologically hypoxic environment.Therefore,the study of angiogenesis and osteogenesis in hypoxic environment is closer to the microenvironment in vivo. OBJECTIVE:To explore the influence of Wenshen Tongluo Zhitong(WSTLZT)formula on H-type bone microvascular endothelial cell/bone marrow mesenchymal stem cell co-culture system in hypoxia environment and its related mechanism. METHODS:Enzyme digestion method and flow sorting technique were used to isolate and identify H-type bone microvascular endothelial cells.Mouse bone marrow mesenchymal stem cells were isolated and obtained by bone marrow adhesion method.H-type bone microvascular endothelial cell/bone marrow mesenchymal stem cell hypoxic co-culture system was established using Transwell chamber and anoxic culture workstation.WSTLZT formula powder was used to intervene in each group at a mass concentration of 50 and 100 μg/mL.The angiogenic function of H-type bone microvascular endothelial cells in the co-culture system was evaluated by scratch migration test and tube formation test.The osteogenic differentiation ability of bone marrow mesenchymal stem cells in the co-cultured system was evaluated by alkaline phosphatase staining and alizarin red staining.The protein and mRNA expression changes of PDGF/PI3K/AKT signal axis related molecules in H-type bone microvascular endothelial cells in the co-cultured system were detected by Western Blotting and q-PCR,respectively. RESULTS AND CONCLUSION:(1)Compared with the normal oxygen group,the scratch mobility and new blood vessel length of H-type bone microvascular endothelial cells were significantly higher(P<0.05);the osteogenic differentiation capacity of bone marrow mesenchymal stem cells was higher(P<0.05);the expression of PDGF/PI3K/AKT axis-related molecular protein and mRNA increased(P<0.05)in the hypoxia group.(2)Compared with the hypoxia group,scratch mobility and new blood vessel length were significantly increased in the H-type bone microvascular endothelial cells(P<0.05);bone marrow mesenchymal stem cells had stronger osteogenic function(P<0.05);the expression of PDGF/PI3K/AKT axis-related molecular proteins and mRNA further increased(P<0.05)after treatment with different dose concentrations of WSTLZT formula.These findings conclude that H-type angiogenesis and osteogenesis under hypoxia may be related to the PDGF/PI3K/AKT signaling axis,and WSTLZT formula may promote H-type vasculo-dependent bone formation by activating the PDGF/PI3K/AKT signaling axis,thereby preventing and treating osteoporosis.

Objective To compare the differences in the levels of lactate dehydrogenase(LDH),creatine kinase(CK),and neuron-specific enolase(NSE)in the cerebrospinal fluid(CSF)between the patients with purulent meningitis(PM)and those with tuberculous meningitis(TBM)and evaluate the utility of the three biomarkers in the differentiation of PM and TBM.Methods Thirty-five PM patients and 45 TBM patients who attended the Department of Neurology from December 2019 to December 2021 were enrolled in this study.The CSF samples were collected from the patients before treatment.The levels of LDH,CK,NSE,and glucose,protein,and chloride in CSF were measured and compared between PM and TBM patients.The correlation between the biomarkers in CSF was analyzed by Pearson correlation coefficient.Linear regression analysis was performed to analyze the risk factors for the occurrence of TBM.Receiver operating characteristic(ROC)curves were plotted to evaluate the discriminative value of CSF LDH,CK,NSE alone or in combination in differential diagnosis of PM and TBM.Results Patient age,gender,clinical features such as fever,pathological signs,vomiting,limb twitching,and CSF levels of glucose and protein did not show significant difference between TBM patients and PM patients(P＞0.05).TBM was associated with significantly higher LDH and NSE levels in CSF and significantly lower CK level and chloride in CSF compared to PM(P＜0.05).Pearson correlation analysis showed that LDH level in CSF was negatively correlated with CK and chloride(r＜0,P＜0.05),and positively correlated with NSE(r＞0,P＜0.05).CK was negatively correlated with NSE(r＜0,P＜0.05),and positively correlated with chloride(r＞0,P＜0.05).NSE was negatively correlated with chloride(r＜0,P＜0.05).Linear regression analysis showed that LDH,CK,NSE,and chloride levels in CSF were all associated with the occurrence of TBM(P＜0.05).ROC curves demonstrated that the AUCs of CSF levels of LDH,CK,NSE alone and in combination for differentiation between PM and TBM were 0.849(95％CI:0.768-0.930),0.858(95％CI:0.779-0.937),0.851(95％CI:0.771-0.931),and 0.954(95％CI:0.911-0.996),respectively.Conclusions The clinical features are similar for PM and TBM patients.However,the levels of LDH,CK,and NSE in CSF are different between PM and TBM.LDH,CK,NSE in combination may improve the differential diagnosis between PM and TBM.

Objective To observe the efficacy and safety of radiotherapy combined with programmed death receptor-1(PD-1)inhibitors and tyrosine kinase inhibitors(TKIs)for the treatment of microsatellite-stabilized(MSS)-type or mismatch-matched repair-normal(pMMR)-type colorectal cancer with liver metastases(CCLM).Methods Case data of 25 patients with MSS-type CCLM admitted to Jiangsu Provincial Cancer Hospital from April 2021 to August 2023 were retrospectively analyzed.They were divided into observation group(n = 12)and control group(n = 13).The observation group was given radiotherapy combined with PD-1 inhibitor and TKI treatment,and the control group was given TKI monotherapy.The baseline data,treatment effect,progression-free survival,and treatment-related adverse reactions of patients in the two groups were compared.Results The difference in baseline data between the two groups was not statistically significant(P＞0.05),the disease control rate(DCR)of the observation group was higher than that of the control group(P＜0.05),the progression-free survival(PFS)of the patients in the observation group was longer than that of the control group,but the difference was not statistically sig-nificant(P＞0.05),and the difference in the incidence of treatment-related adverse events(TRAE)between the two groups was not statistically significant(P＞0.05).Conclusion The treatment regimen of radiotherapy com-bined with PD-1 inhibitors and TKI drugs improved clinical efficacy and did not increase the incidence of adverse events when compared with TKI alone,which is a treatment regimen worthy of further validation.

Objective To investigate the effects of nuclear respiratory factor 1(NRF1)on mitochondrial and cog-nitive dysfunction in Alzheimer's disease(AD)model mice.Methods The 5 × FAD mice were utilized as a mod-el for Alzheimer's disease,and the sparsely labeled AAV virus overexpressing NRF1(AAV-NRF1)was adminis-tered via stereotaxic injection into the brain.The expression of NRF1 in hippocampus was determined by Western blot,the morphology of mitochondria in hippocampus was observed by transmission electron microscope,the den-dritic spines of sparsely labeled neurons in the CA1 region were visualized and quantified using confocal laser mi-croscopy,cognitive and memory functions of mice were evaluated using the Morris water maze test,while electro-physiological methods were employed to detect long-term potentiation(LTP)of synaptic efficacy.Results The ex-pression of NRF1 in the hippocampus was significantly upregulated following stereotactic injection of AAV-NRF1(P＜0.001).This intervention led to notable improvements in mitochondrial morphology within hippocampal neurons,as well as enhanced cognitive and memory functions in mice(P＜0.01).Moreover,there was a significant in-crease in dendritic spine density among neurons located in the CA1 region of the hippocampus(P＜0.001),ac-companied by long-lasting and stable long-term potentiation(LTP)and a substantial elevation in fEPSP slope(P＜0.01).Conclusion The overexpression of NRF1 in a 5 × FAD mouse model of Alzheimer's disease(AD)initia-ted the restoration of mitochondrial dysfunction and enhanced synaptic plasticity,indicating that these alterations may contribute to the therapeutic efficacy of NRF1 overexpression in ameliorating cognitive dysfunction associated with AD.

Objective:To investigate long-term auditory changes and characteristics of Alport syndrome（AS） patients with different degrees of renal injury. Methods:Retrospectively analyzing clinical data of patients diagnosed AS from January 2007 to September 2022, including renal pathology, genetic detection and hearing examination. A long-term follow-up focusing on hearing and renal function was conducted. Results:This study included 70 AS patients, of which 33（25 males, 8 females, aged 3.4-27.8 years） were followed up, resulting in a loss rate of 52.9%.The follow-up period ranged from 1.1to 15.8 years, with 16 patients followed-up for over 10 years. During the follow-up, 10 patients presenting with hearing abnormalities at the time of diagnosis of AS had progressive hearing loss, and 3 patients with new hearing abnormalities were followed up, which appeared at 5-6 years of disease course. All of which were sensorineural deafness. While only 3 patients with hearing abnormalities among 13 patients received hearing aid intervention. Of these patients,7 developed end-stage renal disease（ESRD）, predominantly males （6/7）. The rate of long-term hearing loss was significantly different between ESRD group and non-ESRD group（P=0.013）. There was no correlation between the progression of renal disease and long-term hearing level（P>0.05）. kidney biopsies from 28 patients revealed varying degrees of podocyte lesion and uneven thickness of basement membrane. The severity of podocyte lesion was correlated with the rate of long-term hearing loss（P=0.048）, and there was no correlation with the severity of hearing loss（P>0.05）. Among 11 cases, theCOL4A5mutationwas most common （8 out of 11）, but there was no significant correlation between the mutation type and hearing phenotype（P>0.05）. Conclusion:AS patients exhibit progressive hearing loss with significant heterogeneity over the long-term.. THearing loss is more likely to occur 5-6 years into the disease course. Hearing abnormalities are closely related to renal disease status, kidney tissue pathology, and gene mutations, emphasizing the need for vigilant long-term hearing follow-up and early intervention.

Objective To investigate the imaging features of papillary tumor of the pineal region(PTPR).Methods The ima-ging data of 10 patients with PTPR confirmed by operation and pathology were analyzed retrospectively.Results All lesions were located in the posterior commissure area of the posterior inferior wall of the third ventricle.All lesions were heterogeneously hyper-intensity on T1WI and hyperintensity on T2WI.Multiple small cysts or microcapsules signal intensity were observed within the tumor.Of all 10 lesions,there were 9 lesions with high signal intensity within or at the edge of the lesion on T1WI.All lesions showed restricted diffusion.All 10 cases showed uneven and obvious enhancement patterns.Midbrain tectum was compressed and moved backward in 5 cases,moved downward in 2 cases,moved forward and downward in 1 case,and was not clearly displayed in other 2 cases.One case was disseminated and 1 case was hyperperfusion.There were all 10 cases with obstructive hydrocephalus and equal or slightly high density on CT imaging,and 4 cases with calcification.Conclusion Imaging characteristics of PTPR included the lesions centered on the posterior commissure,compressed tectum with backward and downward,multiple small cysts or micro-capsules components within the tumor,hyperintensity on T1WI,and uneven and obvious enhancement patterns.

Objective:This study aimed to compare the audiological characteristics between children with unilateral auditory neuropathy (UAN) and single-sided deafness (SSD) to establish a valid basis for the differential diagnosis of children with UAN.Methods:A retrospective analysis was conducted on audiological and imaging evaluations of children with UAN and SSD who were treated at Beijing Children′s Hospital of Capital Medical University between May 2015 and June 2023. There were 17 children with UAN, comprising 10 males and 7 females, with an average age of 4.7 years. Additionally, there were 43 children with SSD, consisting of 27 males and 16 females, with an average age of 6.5 years. Audiological assessments included Auditory brainstem response (ABR), Steady-state auditory evoked potential (ASSR), Behavioural audiometry, Cochlear microphonic potential (CM), Distortino-product otoacoustic emission (DPOAE), and acoustic immittance test. The results of the audiological assessment and imaging phenotypic between the two groups of children were compared and analyzed by applying SPSS 27.0 statistical software.Results:(1) The UAN group (77.8%) had a significantly higher rate of ABR wave III L than the SSD group (20.9%) ( P<0.01). The PA thresholds at 500 Hz and 1 000 Hz of children with SSD were higher than those of children with UAN, while the ASSR thresholds at 500 Hz, 1000 Hz, 2 000 Hz, and 4 000 Hz of children with SSD were significantly higher than those of children with UAN ( P<0.05). (2) The degree of hearing loss in both UAN and SSD children was predominantly complete hearing loss. The percentage of complete hearing loss was significantly higher (χ2=4.353, P=0.037) in the SSD group (93.0%, 40/43) than in the UAN group (63.6%, 7/11). However, the percentage of profound hearing loss was significantly higher in the UAN group (27.3%, 3/11) than in the SSD group (2.3%, 1/43) ( Fisher′s exact test, P=0.023). In terms of hearing curve configuration, the percentage of flat type was significantly higher in the SSD group (76.7%, 33/43) than in the UAN group (36.4%, 4/11). The proportion of the UAN group (27.3%, 3/11) was significantly higher than that in the SSD group (2.3%, 1/43) in ascending type ( P<0.05). There were no statistically significant differences in the hearing curves of the declining type and other types between the two groups ( P>0.05). (3) The proportion of imaging assessment without abnormality was significantly more common in the UAN group (81.8%) than in the SSD group (37.1%) (χ2=6.695, P=0.015). Conclusions:Compared to children with SSD, the occurrence of wave III L on the ABR test was significantly more common in children with UAN. The percentage of ascending hearing curves was significantly higher in children with UAN than in children with SSD. ASSR thresholds were significantly lower in children with UAN. The normal imaging phenotype was significantly more common in children with UAN than in children with SSD.

Objective To investigate the reliability and validity of the assessment tools of Brief ICF Core Sets for Arthroplasty of Knee Osteoarthritis in Perioperative Period(ICSAKOPP). Methods From May,2022 to April,2023,320 patients undergoing knee arthroplasty were selected in Peking University Third Hospital,China-Japan Friendship Hospital,Peking University First Hospital and Chinese PLA General Hospital.Trained assessors used Brief ICSAKOPP to evaluate all enrolled patients before arthroplasty,three days(±one day)after arthroplasty,three weeks(±one week)after arthroplasty,and three months(±one month)after ar-throplasty.Western Ontario and McMaster Universities Osteoarthritis Index(WOMAC)scores were recorded at the same time.Five professionals were asked to score all the items of Brief ICSAKOPP,and the content validity index(CVI)was caculated. Results A total of 64 cases were dropped down.CVI of all the items of the Brief ICSAKOPP were above 0.8,with a av-erage CVI of the scale of 0.938.The Cronbach's α coefficient of the Brief ICSAKOPP was 0.813.There was a moderate correlation(r=0.681,P<0.001)between the overall Brief ICSAKOPP and WOMAC scores,as well as body functional dimension score(r=0.668,P<0.001)and activities and participation dimension score(r=0.657,P<0.001). Conclusion Brief ICSAKOPP is good in content validity,internal consistency reliability and criterion validity.

Objective To investigate the value of serum angiotensin-converting enzyme 2(ACE2),tumor necrosis factor-like weak inducer of apoptosis(TWEAK)and CC motif chemokine ligand 5(CCL5)levels in the diagnosis and severity assessment of attention deficit hyperactivity disorder(ADHD)in children.Methods From October 2022 to October 2023,125 children with ADHD in Hebei Children's Hospital were selected as ADHD group,and 105 healthy children in Hebei Maternal and Child Health Center were selected as control group.According to the Clinical Global Impressions-Severity(CGI-S),the children were separated into a mild to moderate group(n=83)and a severe group(n=42).ELISA was applied to detect levels of ACE2,TWEAK,CCL5,luteinizing hormone(LH),and prolactin(PRL).The combined raven test(CRT)and conners parental symptom questionnaire(PSQ)were applied to score the cognitive and behavioral status of children with disabilities.Spearman correlation was used to analyze the correlation among serum ACE2,TWEAK,and CCL5 with CGI-S,CRT,and PSQ scores in the severe group.Receiver operating characteristic(ROC)curve was applied to analyze the diagnostic value of ACE2,TWEAK,and CCL5 for ADHD and severity.Results The serum ACE2(284.35±92.34 pg/ml)and TWEAK(2.56±0.76 pg/ml)levels in children with ADHD were lower than those in the control group(379.23±106.28 pg/ml,3.52±1.12 pg/ml),while CCL5(7.36±2.37 ng/ml)level was higher than that in the control group(5.24±1.63 ng/ml),and the differences were statistically significant(t=7.244,7.703,7.753,all P＜0.05).The levels of CRT,serum ACE2 and TWEAK in the severe group were lower than those in the mild to moderate group(t=5.318,6.686,6.490),while the levels of PSQ and CCL5 were higher than those in the mild to moderate group(t=5.220,6.134),and the differences were statistically significant(all P＜0.05).Spearman correlation analysis results showed that the serum ACE2 and TWEAK levels in the severe group were negatively correlated with CGI-S and PSQ scores(r=-0.432,-0.453;-0.421,-0.426,all P＜0.001),but positively correlated with CRT scores(r=0.427,0.418,all P＜0.000 1).CCL5 was positively correlated with CGI-S and PSQ scores(r=0.421,0.433,all P＜0.001),but negatively correlated with CRT scores(r=-0.446,P＜0.001).The AUCs for diagnosing ADHD by serum ACE2,TWEAK and CCL5 were 0.814,0.803 and 0.807,respectively,and the AUC of the combined diagnosis of the three was 0.945,which was better than individual diagnosis(Z=5.439,4.258,5.576,all P＜0.001).The AUCs for diagnosing severe ADHD by serum ACE2,TWEAK and CCL5 were 0.853,0.796 and 0.805,respectively,and the AUC of the combined diagnosis of the three was 0.930,which was better than the individual diagnosis(Z=2.604,3.851,3.567,all P＜0.001).Conclusion Serum ACE2 and TWEAK are low expressed in the serum of children with ADHD,while CCL5 is highly expressed.The expression levels of the three are correlated and have high diagnostic value for the occurrence and severity of ADHD.
