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.

Nonalcoholic steatohepatitis （NASH） is a chronic liver disease with the main pathological features of hepatic steatosis， inflammatory cell infiltration， and interstitial fibroplasia， and it is an important risk factor for liver fibrosis， liver cirrhosis， and hepatocellular carcinoma. NOD-like receptor protein 3 （NLRP3） inflammasome is the core of innate immunity， and the abnormal activation of NLRP3 inflammasome is closely associated with the development and progression of NASH， which involves multiple links such as inflammatory response and oxidative stress. A large number of studies have shown that the active ingredients of traditional Chinese medicine （TCM） and TCM compound prescriptions can improve oxidative stress， regulate lipid metabolism， and alleviate liver inflammation by regulating NLRP3 inflammasome. TCM treatment applied in clinical practice has achieved a good therapeutic effect， while inflammasome is one of the key pathways or targets for TCM in improving NASH. This article reviews the mechanism of action of NLRP3 inflammasome in NASH and the research advances in TCM intervention of NLRP3 inflammasome， in order to provide ideas for the clinical TCM treatment of NASH， as well as reference targets and research directions for the research and development of new TCM drugs.

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 study the intervention effects of Wenshen Tongluo Zhitong Recipe(WTZR)on macrophage senes-cence and senile osteoporosis.METHODS The senescent macrophage model was established using hydrogen peroxide(H2 O2)and subsequently divided into four groups:control,model,low-dose drug-treated serum,and high-dose drug-treated serum.β-galactosidase staining,Western blot and qPCR were employed to evaluate the mRNA expression of senescence markers p21 and p53.ROS staining and JC-1 staining were applied to assess mitochondrial function in macrophages.The mRNA levels of Interleukin(IL)-6,IL-10,CD206,and inducible nitric oxide synthase(iNOS)were determined by qPCR analysis.Immunofluorescence was used to evaluate argi-nase(ARG1)and iNOS protein expressions for assessing the impact of drug-containing serum on macrophage polarization.qPCR analy-sis was conducted to measure osteocalcin(OCN),collagen type Ⅰ alpha 1(Col1a1),runt-related transcription factor 2(Runx2)mRNA levels as osteoblast-related markers;ALP staining along with alizarin red staining were performed to evaluate the effect of macrophage conditioned medium treated with drug-containing serum on bone marrow mesenchymal stromal cell(BMSC)osteogenic differentiation.C57BL/6J mice were randomly allocated into four groups:control group,model group,WTZR low-dose group,and WTZR high-dose group.The senile osteoporosis(SOP)mouse model was established by D-galactose.Micro-CT scanning analyzed fe-mur microstructure while HE staining detected pathological changes in femur bone tissue samples collected from each experimental con-dition.Furthermore,Western blot was used to detect the senescence-related molecules p21 and p53 and the osteogenesis-related mark-ers OCN and Runx2,qPCR analysis measured tibial expression levels of senescence-related molecules(p21,p53)as well as macro-phage polarisation-related molecules(IL-6,iNOS,CD206,and IL-10)to assess the effect of this compound on a mouse model simula-ting SOP.RESULTS Following intervention with serum containing WTZR,there was a significant decrease in the number of senes-cent positive cells compared to the model group.Additionally,there was a notable decrease in p21 and p53 mRNA and proteins expres-sion(P＜0.05,P＜0.01,P＜0.001).Furthermore,drug-containing WTZR effectively inhibited ROS production induced by H2 O2 and mitigated mitochondrial membrane potential reduction in macrophages(P＜0.05,P＜0.001).Treatment with drug-containing WTZR re-sulted in down-regulated mRNA expression of M1-related gene iNOS(P＜0.05)while up-regulating mRNA expression of M2-related genes CD163 and CD206(P＜0.05).The drug-containing WTZR significantly reduced fluorescence intensity for iNOS(P＜0.01)while increasing ARG1(P＜0.05)fluorescence intensity.Moreover,conditioned medium from macrophages treated with drug-containing ser-um increased ALP positive cell count(P＜0.01,P＜0.001),alizarin red positive area(P＜0.05),as well as Col1a1,Runx2 and OCN mRNA expression levels(P＜0.05,P＜0.01).The Tb.N,BMD,and BV/TV were significantly higher in the WTZR group compared to the model group(P＜0.05,P＜0.01,P＜0.001);meanwhile,Tb.Sp was notably lower than that observed in the model group(P＜0.05,P＜0.01);bone trabeculae were significantly improved,increased in number and widened.Additionally,the compound could significantly inhibit the D-galactose induced up-regulation of tibial senescence-related genes and proteins p21 and p53(P＜0.05,P＜0.001,P＜0.0001),promote the expression of osteogenesis-related markers OCN and Runx2 protein(P＜0.01,P＜0.0001),promote the down-regulation of M1 related genes IL-6 and iNOS(P＜0.05),and promote the expression of M2 related genes IL-10 and CD206(P＜0.05,P＜0.01).CONCLUSION Wenshen Tongluo Zhitong Recipe may play an anti-osteoporosis effect by inhibiting macrophage senescence and promoting the osteogenic differentiation of BMSC.

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 explore the recovery of abdominal function and and satisfaction rate in patients who received lower abdominal skin flap repair of extensive soft tissue defects in the limbs based on three-dimensional computed tomography angiography(3D-CTA) technology.Methods:A retrospective study was performed to analyze clinical data from patients with extensive skin and soft tissue defects in the limbs, who were admitted to Shandong Provincial Third Hospital between March 2017 and February 2022. Patients were categorized into two groups: the superficial inferior epigastric artery (SIEA) group and the deep inferior epigastric perforator (DIEP) group, with SIEA flaps and DIEP flaps utilized respectively for tissue defect repair. Based on 3D-CTA imaging, the distribution range and vessel diameters of bilateral SIEA, superficial inferior epigastric veins (SIEV), and DIEP were delineated, facilitating the design and harvest of SIEA and DIEP flaps. Comparisons were drawn between preoperative 3D-CTA findings on the course and distribution of SIEA and SIEV, and intraoperative anatomical observations. In addition, the concordance between vessel diameters and pedicle lengths determined via preoperative 3D-CTA and intraoperative measurements was assessed. The flap survival, wound healing and surveyed patients’ satisfaction with wound repair were analyzed. A customized evaluation scale was utilized to assess abdominal contour one year post-surgery, scoring from 5 to 25, with higher scores indicating better outcomes. The abdominal health module of the BREAST-Q scale evaluated patients’ satisfaction with abdominal function preoperatively, three months postoperatively, and one year postoperatively, scoring from 20 to 100, with increasing scores indicating greater satisfaction. The measurement data that conform to the normal distribution were expressed as Mean±SD, and the comparison between the two groups was performed using independent samples t-test. The comparison were conducted at multiple time points, repeated measures analysis of variance was performed, and for the comparison of scores within the group, paired t-test was applied. Results:A total of 21 patients were included, 3 males and 18 females, with an age range of 21 to 60 years and a mean age of 41 years. The range of skin and soft tissue defects was from 10.0 cm × 5.0 cm to 22.0 cm × 14.0 cm, and the range of skin flap harvesting was from 11.0 cm × 6.0 cm to 23.0 cm × 15.0 cm. There were 11 cases in the SIEA group and 10 cases in the DIEP group. Preoperative 3D-CTA examination showed that the course and distribution of SIEA and SIEV were consistent with intraoperative anatomical observations. There was no statistically significant difference in the comparison of vessel diameters, pedicle lengths, and actual measurements between preoperative 3D-CTA examination and intraoperative measurements (all P > 0.05). No flap necrosis occurred postoperatively, wound healing was uneventful in all cases. At 1 year postoperatively, there was no statistically significant difference in abdominal contour scores between the SIEA and DIEP groups [(21.96±3.51) points vs. (21.62±3.17) points, P > 0.05]. Comparison of preoperative abdominal function satisfaction scores between the SIEA and DIEP groups showed no statistically significant difference [(87.56 ± 5.70) points vs. (85.79 ± 6.33) points, P > 0.05]. However, at 3 months and 1 year postoperatively, the SIEA group had higher scores than the DIEP group [at 3 months postoperatively, (77.62 ± 7.68) points vs. (65.21 ± 8.27) points; at 1 year postoperatively, (86.93 ± 5.65) points vs. (77.59 ± 5.92) points; both P < 0.01], indicating higher abdominal function satisfaction of the SIEA group postoperatively. The scores of both the SIEA and DIEP groups decreased at 3 months postoperatively compared to preoperative scores (both P < 0.01). At 1 year postoperatively, the score of the SIEA group was similar to preoperative levels, with no statistically significant difference ( P > 0.05), while the score of the DIEP group remained lower than preoperative levels ( P < 0.01). Conclusion:Reconstruction of extensive skin and soft tissue defects in the limbs using SIEA flaps, without injury to the deep tissues of the abdominal wall, allows for near-complete restoration of abdominal function and appearance to preoperative levels, with minimal impact on the donor site. Preoperative 3D-CTA reveals the anatomical variations in the vascular supply of SIEA flaps among individuals, achieving comparable wound repair outcomes to other lower abdominal flaps.
