The traditional Chinese medicine （TCM） myocardial infarction （MI） unit is a standardized， regulated， and continuous integrated care unit guided by TCM theory and built upon existing chest pain centers or emergency care units. This unit emphasizes multidisciplinary collaboration and forms a restructured clinical entity without altering current departmental settings， offering comprehensive diagnostic and therapeutic services with full participation of TCM in the treatment of MI. Its core medical model is patient-centered and disease-focused， providing horizontally integrated TCM-based care across multiple specialties and vertically constructing a full-cycle treatment unit for MI， delivering prevention， treatment， and rehabilitation during the acute， stable， and recovery phases. Additionally， the unit establishes a TCM-featured education and prevention mechanism for MI to guide patients in proactive health management， reduce the incidence of myocardial infarction， and improve quality of life.

Objective To observe the effect of combination of partial body weight support and functional electrical stimulation on lower limb motor function for stroke patients. Methods From January,2023 to February,2024,60 stroke patients from Rehabilitation Hospital of Chancheng District People's Hospital in Foshan City were randomly divided into control group(n=30)and observation group(n=30).The control group received routine rehabilitation,while the observation group received a combination of ce-lestial orbit system and functional electrical stimulation in addition,for three weeks.They were assessed with Balance assessment and training system,Berg Balance Scale(BBS),Fugl-Meyer Assessment-Lower Extremities(FMA-LE)and Holden Functional Ambulation Category(FAC)before and after treatment. Results X-axis trajectory length,average speed of swaying,total wobble trajectory,Y-axis trajectory length,trajectory length per unit area,BBS score,FMA-LE score and FAC score improved in both groups after treatment(|t|＞4.809,P＜0.001);and all the indexes improved more in the observation group than in the control group(|t|＞2.268,P＜0.05),except X-axis trajectory length and average speed of swaying. Conclusion Supplement of the combination of partial body weight support and functional electrical stimulation is more effective on lower limb motor function,balance and walking for stroke patients.

Objective　To analyze the drug resistance, genomic information, and genetic relationships of Extended-Spectrum β-Lactamases (ESBLs)-positive Acinetobacter strains colonized in the intestinal tract of children with and without diarrhea, and to explore the carrying status and distinguishing features of two group ESBLs-positive Acinetobacter strains. Methods　A total of 842 fresh fecal samples were collected from children with and without diarrhea from a hospital in Shanghai, 2017-2019. ESBLs-resistant Acinetobacter strains were isolated and identified, followed by a drug sensitivity test and whole genome sequencing. A phylogenetic tree was constructed to explore the genetic relationship between Acinetobacter baumannii strains in this study and those isolated in China during the same period. Results　A total of 13 ESBLs-positive Acinetobacter strains were isolated, including 11 strains in the diarrhea group and two strains in the non-diarrhea group, the positive rate of ESBLs strains in the diarrhea group was significantly higher than that in the non-diarrhea group (χ2=5.206, P=0.023). All strains showed a high resistance rate to the first-generation cephalosporins (100.0%) and the second-generation cephalosporins (100.0%), with a multidrug resistance rate of 53.8% (7/13). There was no significant difference in the rates of resistance to individual antibiotics and multidrug resistance between the two groups (P>0.05). The blaOXA resistance gene was carried by all strains on the chromosome, which encode enzymes that hydrolyze clinically important antibiotics such as third-generation cephalosporins and carbapenems. Adhesion-type virulence genes were carried by 92.3% (12/13) of the strains, and secretion-type virulence genes were present in 84.6% (11/13). Furthermore, 92.3% (12/13) of ESBLs-positive Acinetobacter strains carried plasmids, with one A. baumannii strain isolated from a non-diarrhea child carrying seven types of plasmids. The analysis of the phylogenetic relationship indicated that A. baumannii strains isolated in this study formed a clonal cluster, and also clustered with some strains from southern China during the same period. Conclusions　ESBLs-positive Acinetobacter strains isolated from children with and without diarrhea exhibited serious drug resistance, carrying multiple resistance and virulence genes, as well as multiple plasmids. Carrying multiple plasmids may facilitate the horizontal transmission risk of drug-resistance genes and virulence genes, indicating the need to pay attention to the characteristics of intestinal colonized ESBLs-positive Acinetobacter strains in children and strengthen the monitoring of drug-resistant bacteria colonized in the intestine in healthy children.

ObjectiveTo construct a traditional Chinese medicine （TCM） syndrome diagnosis and prescription model for coronary heart disease with the improved Transformer algorithm. MethodTaking the syndrome elements of coronary heart disease as key links， the model was constructed based on the clinical diagnosis and treatment principle of "symptoms-syndrome elements-syndrome-treatment method-prescription-medicine （dose）". The basic logic of improved Transformer algorithm was constructed with multi-head attention mechanism， compound term vector and dropout， in order to form the model with functions of TCM syndrome elements judgment， syndrome diagnosis， prescription recommendation. After the model was constructed， it was trained by 8 030 cases. And 100 cases with TCM prescriptions were randomly selected for testing， and the model output prescriptions were compared with those of clinicians for qualitative evaluation of the model. ResultThe improved Transformer with multi-head attention improved the accuracy of the model. The model was consistent with clinicians in the judgment of main syndromes and the selection of prescriptions. Whereas there was a certain room for improvement in the addition and subtraction of medicines. ConclusionThe improved Transformer model can improve the accuracy and stability of output， which is an embodiment of the intelligent development of TCM.

ObjectiveTo construct the syndrome differentiation and treatment process in the diagnosis and treatment guideline into a visual knowledge graph using knowledge graph technology， and visualize the process from the input of clinical manifestations to the output of corresponding traditional Chinese medicine （TCM） diagnosis and prescriptions through programs， to visually display the diagnosis and treatment process as well as the data relationship for TCM practitioners. This paper facilitated the standardized and normalized TCM diagnosis and treatment of coronary heart disease， and provided technical support for the inheritance and promotion of TCM diagnosis and treatment. MethodNeo4j and py2neo were used to construct a knowledge graph based on the Guideline for Diagnosis and Treatment of Coronary Heart Disease with Stable Angina Pectoris published by China Association of Chinese Medicine Cardiovascular Disease Branch. A knowledge graph regarding the input of clinical manifestations was built through programs， visually displaying the standardized TCM diagnosis and treatment process of coronary heart disease with stable angina pectoris. ResultThe structured data were extracted from the guideline by py2neo connecting to Neo4j and imported into Neo4j to construct the knowledge graph of TCM diagnosis and treatment of coronary heart disease with stable angina pectoris， which had graph database query function. ConclusionAiming at the problems existing in the inheritance of TCM diagnosis and treatment， this paper proposed a diagnosis and treatment guideline integrating the experience of TCM experts and evidence-based evidence for coronary heart disease with stable angina pectoris， and realized the visualization process of knowledge graph based on TCM diagnosis and treatment guideline and the experience of TCM experts. It is helpful to intuitively display the whole TCM diagnosis and treatment process from symptom input to prescriptions and inherit TCM experience， providing a new paradigm for standardized and normalized TCM diagnosis and treatment.

BACKGROUND: Patients with mass-forming pancreatitis (MFP) or pancreatic ductal adenocarcinoma (PDAC) presented similar clinical symptoms, but required different treatment approaches and had different survival outcomes. This meta-analysis aimed to compare the diagnostic performance of contrast-enhanced ultrasound (CEUS) and contrast-enhanced computed tomography (CECT) in differentiating MFP from PDAC. METHODS: A literature search was performed in the PubMed, EMBASE (Ovid), Cochrane Library (CENTRAL), China National Knowledge Infrastructure (CNKI), Weipu (VIP), and WanFang databases to identify original studies published from inception to August 20, 2021. Studies reporting the diagnostic performances of CEUS and CECT for differentiating MFP from PDAC were included. The meta-analysis was performed with Stata 15.0 software. The outcomes included the pooled sensitivity, specificity, positive likelihood ratio (+LR), negative likelihood ratio (-LR), diagnostic odds ratio (DOR), and summary receiver operating characteristic (SROC) curves of CEUS and CECT. Meta-regression was conducted to investigate heterogeneity. Bayesian network meta-analysis was conducted to indirectly compare the overall diagnostic performance. RESULTS: Twenty-six studies with 2115 pancreatic masses were included. The pooled sensitivity and specificity of CEUS for MFP were 82% (95% confidence interval [CI], 73%-88%; I2  = 0.00%) and 95% (95% CI, 90%-97%; I2  = 63.44%), respectively; the overall +LR, -LR, and DOR values were 15.12 (95% CI, 7.61-30.01), 0.19 (95% CI, 0.13-0.29), and 78.91 (95% CI, 30.94-201.27), respectively; and the area under the SROC curve (AUC) was 0.90 (95% CI, 0.87-92). However, the overall sensitivity and specificity of CECT were 81% (95% CI, 75-85%; I2  = 66.37%) and 94% (95% CI, 90-96%; I2  = 74.87%); the overall +LR, -LR, and DOR values were 12.91 (95% CI, 7.86-21.20), 0.21 (95% CI, 0.16-0.27), and 62.53 (95% CI, 34.45-113.51), respectively; and, the SROC AUC was 0.92 (95% CI, 0.90-0.94). The overall diagnostic accuracy of CEUS was comparable to that of CECT for the differential diagnosis of MFP and PDAC (relative DOR 1.26, 95% CI [0.42-3.83], P  > 0.05). CONCLUSIONS CEUS and CECT have comparable diagnostic performance for differentiating MFP from PDAC, and should be considered as mutually complementary diagnostic tools for suspected focal pancreatic lesions.

BACKGROUND: Clinical trial evidence is limited to identify better topical non-steroidal anti-inflammatory drugs (NSAIDs) for treating knee osteoarthritis (OA). We aimed to compare the clinical efficacy and safety of flurbiprofen cataplasms (FPC) with loxoprofen sodium cataplasms (LSC) in treating patients with knee OA. METHODS: This is an open-label, non-inferiority randomized controlled trial conducted at Peking University Shougang Hospital. Overall, 250 patients with knee OA admitted from October 2021 to April 2022 were randomly assigned to FPC and LSC treatment groups in a 1:1 ratio. Both medications were administered to patients for 28 days. The primary outcome was the change of pain measured by visual analog scale (VAS) score from baseline to day 28 (range, 0-10 points; higher score indicates worse pain; non-inferiority margin: 1 point; superiority margin: 0 point). There were four secondary outcomes, including the extent of pain relief, the change trends of VAS scores, joint function scores measured by the Western Ontario and McMaster University Osteoarthritis Index (WOMAC), and adverse events. RESULTS: Among 250 randomized patients (One patient without complete baseline record in the flurbiprofen cataplasms was excluded; age, 62.8 ± 10.5 years; 61.4% [153/249] women), 234 (93.6%) finally completed the trial. In the intention-to-treat analysis, the decline of the VAS score for the 24-h most intense pain in the FPC group was non-inferior, and also superior to that in the LSC group (differences and 95% confidence interval, 0.414 (0.147-0.681); P <0.001 for non-inferiority; P = 0.001 for superiority). Similar results were observed of the VAS scores for the current pain and pain during exercise. WOMAC scores were also lower in the FPC group at week 4 (12.50 [8.00-22.50] vs . 16.00 [11.00-27.00], P = 0.010), mainly driven by the dimension of daily activity difficulty. In addition, the FPC group experienced a significantly lower incidence of adverse events (5.6% [7/124] vs . 33.6% [42/125], P <0.001), including irritation, rash and pain of the skin, and sticky hair uncovering pain. CONCLUSIONS This study suggested that FPC is superior to LSC for treating patients with knee OA in pain relief, joint function improvement, and safety profile.

Human hair, a kind of natural fiber mainly composed of keratin and keratin-associated proteins, is a good biological sample that can be used to characterize the status of the body in a certain period of time. It is of highly importance in the detection of drugs, alcohol and stimulants because of the advantages of low cost, easy collection, easy transportation and storage. Proteomics is an emerging technology widely used in the field of life sciences to study protein expression and regulation at the holistic level. Investigating the composition and dynamic changes of hair proteins in different populations would have great potential in finding disease markers and distinguishing personal traits. In this paper, the structure and composition of hair, the changes of hair composition under psychological stress, and the research progress of hair proteomics were comprehensively reviewed. This will help using hair proteomics to identify body characteristics.

The anterior cruciate ligament (ACL) injury is a common sports injury that has a significant impact on knee function and patients′ mobility. With the popularity of national fitness campaign in China, the incidence of ACL injury is increasing year by year. Currently, there still lacks clinical standards or guidelines on how to choose appropriate treatment methods, surgical plans and rehabilitation protocols for ACL injury. In order to timely reflect the new treatment concept of ACL injury, standardize its diagnosis and treatment and improve the curative effect, the Sports Medicine Society of Chinese Research Hospital Association and the Editorial Board of Chinese Journal of Trauma organized domestic orthopedic and sports medicine experts to formulate the "clinical evidence-based guideline for the diagnosis and treatment of anterior cruciate ligament injury (2022 version)" based on the level of evidence-based medicine and in compliance with the principle of scientificity, practicability and advancement. The present guideline includes 12 recommendations for the diagnosis, treatment and rehabilitation of ACL injury in order to provide guidance and assistance for the clinical diagnosis and treatment of ACL injury in China.

Objective:To evaluate the efficacy and safety of docetaxel plus hormone therapy in metastatic prostate cancer.Methods:From April 2016 to April 2019, 204 cases with bone metastatic prostate cancer in the Second Hospital of Tianjin Medical University were analyzed retrospectively. There were 97 patients responded to hormone therapy including 92 cases with high-burden metastasis (more than 4 bone metastases with one or more beyond the axial skeleton) and 5 cases with low-burden metastasis, with average age of 70 years (range 42-87 years) and median prostate specific antigen (PSA) of 74.1 ng/ml (range 11.0-145.0 ng/ml). Among them, there were 35 patients (36.1%) with a Gleason score of 7 or lower, and 62 patients (63.9%) with a Gleason score of 8 or higher. There were 26 patients suffering from bone pain, with average numerical rating scales(NRS) score of 3.7. In addition, there were 107 patients being resistant to hormone therapy, with average age of 73 years (range 56-83 years), and median PSA of 84.5 ng/ml (range 12.4-490.2 ng/ml), including 32 patients (29.9%) with a Gleason score of 7 or lower, and 75 patients (70.1%) with a Gleason score of 8 or higher. Among them, there were 75 patients suffering from bone pain, with average NRS score of 5.4. All patients received continuous hormone therapy combined with docetaxel (at a dose of 75 mg per square meter of body-surface area every 3w, plus prednisone 5 mg twice a day), and PSA progression-free survival (PSA-PFS), NRS score, pain relief, and adverse events were analyzed. Additional analysis of the correlation between PSA-PFS and subgroups with age, PSA level and Gleason score were performed.Results:For patients with metastatic hormone sensitive prostate cancer (mHSPC), 6 (6.2%) cases only received 1-2 cycles of chemotherapy due to different reasons, and the others received 3-6 cycles(average 4.7)with the median follow-up of 15 months. Of patients who received ≥3 cycles, there were 36 cases presenting PSA progression, with the median PSA-PFS of 22 months, average NRS score decline from 3.9 to 3.0, and pain relief rate of 72.0%(18/25). For patients with metastatic castration-resistant prostate cancer (mCRPC), 9 (8.4%)cases only received 1-2 cycles of chemotherapy, and the others received 3-14 cycles (average 5.6). Of patients who received≥3 cycles, there were 51 cases with PSA progression, with the median PSA-PFS of 11 months, average NRS score decline from 5.6 to 4.4, and pain relief rate of 48.6%(35/72). Subgroup analysis showed a significant correlation between PSA level and PSA-PFS for patients with mCRPC( P=0.026). Age or Gleason score was not significantly correlated to PSA-PFS in mHSPC or mCRPC( P>0.05). For patients with mHSPC, grade 3 or 4 neutropenia occurred in 17 cases(17.5%), nausea and vomiting in 27 cases(27.8%), and fatigue in 25 cases(25.8%). For patients with mCRPC, grade 3 or 4 neutropenia occurred in 24 cases (22.4%), nausea and vomiting in 34 cases(31.8%), and fatigue in 26 cases(24.3%). Allergic reaction and sensory neuropathy toxicity were occasional. Conclusion:Efficacy of docetaxel plus hormone therapy was confirmed in metastatic prostate cancer and adverse events were tolerable.
