Severe burns and trauma frequently lead to the skin barrier disruption and development of moist burn wound, which can trigger sepsis, septic shock, and even death. Immunodysfunction is closely associated with poor prognosis. In-depth research on the mechanisms of natural and adaptive immune dysfunction can help reveal the essence of the disease. Currently, elucidating the underlying mechanisms of immune dysfunction has become a critical research priority. Such investigations may provide fundamental insights into disease pathogenesis. Besides, accurate immune function assessment holds significant value for early detection of immune dysfunction, judgment of the severity of the condition, precise prediction of the prognosis, and guidance of clinical treatment. Implementing immunomodulatory treatment based on the pathophysiological mechanisms and evaluation results is a necessary approach to restoring the immune function, reducing mortality rate, and improving the prognosis of the patients with sepsis following severe burns and trauma. To this end, the authors systematically examined the characteristics and mechanisms of immune dysfunction, immune assessment as well as classification, and corresponding therapeutics in sepsis following severe burns and trauma, thereby providing a reference for the development of precise diagnosis and treatment strategies for immune dysfunction management.

Objective To evaluate the clinical efficacy of hip-knee-ankle active and passive exercise therapy in patients with early-to mid-stage knee osteoarthritis(KOA).Methods A total of 180 patients with early to mid-stage knee osteoarthritis(KOA)were recruited from the First Affiliated Hospital of Hebei University of Tradi-tional Chinese Medicine between March 2023 and March 2024.Patients were randomly assigned to one of four groups:active movement group,passive movement group,combined movement group,and control group,with 45 patients in each group.The active movement group received hip-knee-ankle active movement therapy daily until the end of follow-up.The passive movement group underwent hip-knee-ankle passive movement therapy three times per week for two weeks.The combined movement group received both active and passive therapies.The control group was administered oral celecoxib capsules(200 mg once daily for two weeks).Joint function was assessed in all four groups before treatment,at two weeks post-treatment,and at 14 weeks post-treatment.The primary outcome measure was the WOMAC joint function score,while secondary outcomes included the WOMAC pain score,stiffness score,and quality of life score(SF-12).Results A total of 160 patients completed the trial,with 39 in the active group,42 in the passive group,40 in the combined group,and 39 in the control group.There were no significant differences in baseline characteristics among the groups(P>0.05).Compared to baseline,the WOMAC scores for function,pain,and stiffness in the passive,combined,and control groups decreased significantly at both 2 and 14 weeks post-treatment(P<0.05),while the SF-12 scores increased significantly(P<0.05).Between 2 and 14 weeks post-treat-ment,the active and combined groups showed further significant decreases in WOMAC function,pain,and stiffness scores(P<0.05)and increases in SF-12 scores(P<0.05).At 2 weeks post-treatment,compared to the control group,the passive and combined groups exhibited significantly lower WOMAC function scores(P<0.05),with no significant difference between the passive and combined groups(P>0.05).By 14 weeks post-treatment,the active and combined groups demonstrated significantly lower WOMAC function scores(P<0.05),with the combined group showing a significantly lower score than the active group(P<0.05).Conclusion The four therapeutic approaches demonstrate a certain degree of efficacy in improving joint function for patients with early and mid-stage KOA.The passive therapy group exhibits superior short-term outcomes,while the active therapy group shows better long-term benefits.The combined therapy group presents notable advantages in both short-term and long-term effi-cacy,although its short-term effectiveness does not surpass that of the passive therapy group.It is recommended for patients with early and mid-stage KOA who have underlying gastrointestinal and cardiovascular conditions.

Objective To study the effects of Guizhi Shaoyao Zhimu Decoction on factors related to bone destruction and bone protection in rats with collagen-induced arthritis(CIA)based on osteopro-tegerin(OPG)/receptor activator of NF-κB ligand(RANKL)/receptor activator of NF-κB(RANK)signaling pathway.Methods According to the body weight,60 female Wistar rats were randomly di-vided into the following six groups:the normal group,the model group,the Triperygium wilfordii mul-tiglucoside group(0.01 g/kg),the Guizhi Shaoyao Zhimu Decoction low-dose group(8.6 g/kg),the Guizhi Shaoyao Zhimu Decoction medium-dose group(17.2 g/kg),and the Guizhi Shaoyao Zhimu Decoction high-dose group(34.4 g/kg)(n=10 rats per group).The rats in all groups except for the normal group were given 100 μg bovine type Ⅱ collagen on the 1st and 8th days to establish the CIA model,and was injected into the left foot sole and tail root of the rats.After the successful modeling,the rats were treated by gavage for 4 weeks.The general state,body weight,and arthritis index(AI)score of rats were recorded,and the contents of RANKL and OPG in rat serum were determined by enzyme-linked immunosorbent assay.The mRNA and protein expressions of RANKL,RANK,and OPG in the ankle joint were determined through real-time PCR and Western blotting,respectively.Results Com-pared with the normal group,the general state of the model group was poor,the toe swelling was obvious,the AI score was increased,the serum RANKL content was increased,the serum OPG content was de-creased,and the mRNA and protein expressions of RANKL and RANK in the ankle joint were increased(P＜0.05).Compared with the model group,the degree of toe swelling and the AI score of rats in the Guizhi Shaoyao Zhimu Decoction low-,medium-,and high-dose groups were decreased,the serum RANKL content was decreased,the serum OPG content was increased,the mRNA and protein expres-sions of RANKL and RANK in the ankle joint were decreased,the mRNA and protein expressions of OPG were increased,and the RANKL/OPG ratio of the ankle joint was decreased(P＜0.05).Conclusion Guizhi Shaoyao Zhimu Decoction can improve the destruction of joint bone in CIA rats,and its mecha-nism of action may be related to reducing RANKL level,reducing RANKL/OPG ratio,and regulating bone balance.

From the perspectives of traditional Chinese medicine （TCM） information knowledge base and assisted decision-making knowledge base， the construction status， quality evaluation status and existing problems of current TCM knowledge bases have been sorted out. And based on the quality evaluation strategies and dimensions of know-ledge bases in other disciplines， the evaluation indexes for TCM knowledge base is discussed， and the evaluation framework is initially formed， providing ideas for the improvement of the TCM knowledge base evaluation system. In terms of the evaluation indexes， there are basic evaluation dimensions which include data sources， data collection， and data application. The specific evaluation dimension of the information-based knowledge base is data quality， while that of the assisted decision-making knowledge base is data matching. Except for the data application dimension which counts the valid data items in the database for calculation， other indexes are scored based on the qualitative evaluation of "yes"， "no" or "unknown". The basic evaluation score and the specific evaluation score are added to obtain the total score. The knowledge base is graded according to the score， and the results are presented in the form of grade plus number.

Objective To observe the clinical effect of traditional Chinese medicine bone-setting technique using spinal,pelvi-lower extremity line to treat patients with knee osteoarthritis(KOA).Methods 426 patients with KOA were all from the First Affiliated Hospital of Hebei University of Traditional Chinese Medicine.They were randomly divided into experimental group(384 cases,57 cases of elimination,shedding and termination)by computer generated sequence.Traditional Chinese bone setting techniques were applied with spinal-pelvic-lower limb force line(divided into three parts:lumbar fixed point reduction method,hip joint push-pull and extension method and knee peripheral tendon recovery method every 3 days.2 weeks)treatment;The control group was the waiting treatment group(48 cases,6 cases were eliminated,abscission,termination),which was only used for clinical observation for 2 weeks.The main outcome index was WOMAC pain score.Secondary outcome measures were WOMAC stiffness score,functional score,standardized score and quality of life score(SF-12).The test time points were baseline,2 weeks after enrollment,and follow-up(14 weeks after enrollment).The control group was at baseline and 2 weeks after enrollment.Results Compared with baseline,WOMAC pain score,stiffness score,functional score and standardized score were all decreased in 2 groups 2 weeks after enrollment(P<0.05),but the experimental group was significantly decreased compared with the control group(P<0.001).SF-12 quality of life scores were all higher than before(P<0.001),but the experimental group was significantly higher than the control group(P<0.001).At follow-up,compared with 2 weeks after enrollment,WOMAC pain scores were increased(P<0.001),WOMAC stiffness,joint function and standardized scores were decreased(P<0.001),and SF-12 scores were increased(P<0.001).Conclusion The use of spinal-pelvi-lower extremity line of traditional Chinese medicine bone-setting technique in the treatment of KOA is effective in improving the knee joint function and improving the quality of life of patients,but the short-term effect of pain relief is good,and the long-term effect is not good.Its safety is good,and it can be considered in clinical application for KOA patients with joint dysfunction as the main manifestation.

Cholangiocarcinoma is a malignant tumor with biliary epithelial features.The early diagnosis of cholangiocarcinoma is currently difficult and the treatment outcomes are poor.Its microenvironment includes abundant fibrotic mesenchyme and a variety of cell types,which promote the development and metastasis of cholangiocarcinoma by interacting with tumor cells through mechanisms such as facilitating migration,suppressing the immune response,and inducing angiogenesis and lymphangiogenesis.Immunotherapy is an important tumor treatment approach,and immunotherapy for cholangiocarcinoma has made some progress.This article reviews the characteristics of the immune microenvironment of cholangiocarcinoma,its relationship with immunotherapy,and cutting-edge therapeutic strategies.

Objective: To explore the effectiveness of spinal guidance exercise on adolescents of mild idiopathic scoliosis, so as to provide an experimental reference and method for promoting adolescents spinal health. Methods: From the scoliosis screening, 96 children who met the diagnostic criteria were selected in June 2021, and were divided into the experimental group and the control group, with 48 cases in each group. The experimental group received a 12 week Longji Daoyin exercise training, and the control group received health education, observation and monitoring. Before and after the experiment, the axial trunk rotation (ATR) and scoliosis Cobb angle of the two groups were tested respectively, and the subjective sensation of the patients was measured by Scoliosis Research Society-22(SRS-22) questionnaire. Results: After 12 weeks, the ATR and Cobb angles of the experimental group decreased [( 5.02± 2.85，7.59±3.94)°]，compared to (7.08±2.84)° and (15.84±2.00)° before intervention( t =14.02, 17.09, P < 0.01 ). Scores of functional activity, self image and mental health in the SRS-22 score increased from (4.65±0.14)(3.49±0.21) and (3.99±0.17) to(4.77±0.14)(4.62±0.13)(4.42±0.13)( t =-4.86,-39.12,-13.92, P <0.01 ). The ATR and Cobb angles of the control group increased from (6.94±2.15)° and (15.82±1.76)° to (8.25±2.49)° and (18.63±3.12)°( t =7.44,8.99, P <0.01), and the scores of self image and mental health in the SRS-22 score decreased from (3.49±0.19) and (4.00±0.15) to (3.44±0.18) and (3.94±0.14)( t =-3.74,-4.39, P <0.05). Conclusion Early adolescent idiopathic scoliosis is easy to aggravate during the observation period. Longji Daoyin exercise is of preventive and therapeutic significance.

Electrocardiogram (ECG) signal is an important basis for the diagnosis of arrhythmia and myocardial infarction. In order to further improve the classification effect of arrhythmia and myocardial infarction, an ECG classification algorithm based on Convolutional vision Transformer (CvT) and multimodal image fusion was proposed. Through Gramian summation angular field (GASF), Gramian difference angular field (GADF) and recurrence plot (RP), the one-dimensional ECG signal was converted into three different modes of two-dimensional images, and fused into a multimodal fusion image containing more features. The CvT-13 model could take into account local and global information when processing the fused image, thus effectively improving the classification performance. On the MIT-BIH arrhythmia dataset and the PTB myocardial infarction dataset, the algorithm achieved a combined accuracy of 99.9% for the classification of five arrhythmias and 99.8% for the classification of myocardial infarction. The experiments show that the high-precision computer-assisted intelligent classification method is superior and can effectively improve the diagnostic efficiency of arrhythmia as well as myocardial infarction and other cardiac diseases.
