Medical institutions, with their clinical practice foundation and abundant human use experience data, have become important carriers for the inheritance and innovation of traditional Chinese medicine(TCM) and the "cradles" of the preparation of new TCM. To effectively promote the transformation of new TCM originating from the TCM clinical practice in medical institutions and establish an effective evaluation index system for the transformation of new TCM conforming to the characteristics of TCM, consensus experts adopted the literature research, questionnaire survey, Delphi method, etc. By focusing on the policy and technical evaluation of new TCM originating from the TCM clinical practice in medical institutions, a comprehensive evaluation from the dimensions of drug safety, efficacy, feasibility, and characteristic advantages was conducted, thus forming a comprehensive evaluation system with four primary indicators and 37 secondary indicators. The expert consensus reached aims to encourage medical institutions at all levels to continuously improve the high-quality research and development and transformation of new TCM originating from the TCM clinical practice in medical institutions and targeted at clinical needs, so as to provide a decision-making basis for the preparation, selection, cultivation, and transformation of new TCM for medical institutions, improve the development efficiency of new TCM, and precisely respond to the public medication needs.

The guideline proposed 10 recommendations, aiming to provide a foundation for standardized diagnosis and treatment of postoperative infection in adults with closed lower limb fractures.

Paraplegia caused by spinal cord injury is a serious neurological complication, for which surgery is currently the main treatment method. Due to different surgical approaches, patients are usually expected to maintain a passive prone position for a long time or switch between the supine and prone positions. Affected by multiple factors such as neurogenic sensory disorders, pathological changes in muscle tone and operative duration, the risk of intraoperative acquired pressure injury (IAPI) is significantly increased. Current clinical prevention strategies for IAPI in these patients predominantly focus on localized pressure relief during positioning, lacking systematic, standardized comprehensive prevention protocols or evidence-based guidelines. To address it, Department of Nursing, Orthopedics Branch, China International Exchange and Promotive Association for Medical and Health Care, Spinal Trauma Professional Committee, Orthopedics Branch, Chinese Medical Doctor Association, Nursing Group of Spine and Spinal Cord Professional Committee of Chinese Association of Rehabilitation Medicine organized experts in relevant fields to formulate Guideline for the prevention of intraoperative acquired pressure injury in paraplegic patients with spinal cord injury ( version 2025), based on evidence-based medical evidence and latest research results and clinical practice at home and abroad. Eleven recommendations were put forward from the aspects of preoperative risk assessment, intraoperative prevention strategies, postoperative handover and monitoring, and supportive mechanisms for IAPI prevention, aiming to standardize the prevention measures and management strategies of IAPI in paraplegic patients with spinal cord injury and accelerate the recovery of patients and improve the therapeutic effect.

Body weight abnormalities, including overweight, obesity, and underweight, have become a dual public health challenge in Chinese adults: overweight and obesity lead to a variety of chronic complications, while underweight increases the risks of malnutrition, sarcopenia, and organ dysfunction. To systematically address these issues, multidisciplinary experts in endocrinology, sports science, nutrition, and psychiatry from various regions have held multiple weight management seminars. Based on the latest epidemiological data and clinical evidence, they expanded the guideline to include assessment and intervention strategies for underweight, in addition to the core content of obesity management. This guideline outlines the etiological mechanisms, evaluation methods, and multidimensional management strategies for overweight and obesity, covering key areas such as diagnosis and assessment, medical nutrition therapy, exercise prescription, pharmacological intervention, and psychological support. It is intended to provide a scientific and standardized approach to weight management across the adult population, aiming to curb the rising prevalence of obesity, mitigate complications associated with abnormal body weight, and improve nutritional status and overall quality of life.

Objective To investigate the effects and complications of mitral valve membrane replacement surgery with preservation of mitral valve subvalvular structure on cardiac and valve function.Methods A total of 84 patients receiving mitral valve membrane replacement surgery with preserved mitral valve subvalvular structure in the First Affiliated Hospital of Soochow University from August 2019 to July 2022 were selected as the observa-tion group,and 68 patients receiving mitral valve membrane replacement surgery without preservingmitral valve subvalvular structure were selected as the control group.The surgical indicators,comorbidities,preoperative and postoperative cardiac function,and mitral valve hemodynamic parameters were compared between the two groups.Results There was no statistically significant difference between the observation group and the control group in terms of surgical history,extracorporeal circulation time,aortic occlusion time,postoperative mechanical ventilation time,ICU retention time,and postoperative hospitalization time(P>0.05).At 1,3,and 6 months after surgery,the left ventricular end systolic diameter(LVESD)and left ventricular end diastolic diameter(LVEDD)in the observation group were significantly lower than those in the control group(P<0.05),while the left ventricular short axis shortening rate(LVFS)was significantly higher than that in the control group(P<0.05).There was no statistically significant difference in left ventricular ejection fraction(LVEF)between the observation group and the control group at 1,3,and 6 months after surgery(P>0.05).There was no statistically significant difference(P>0.05)in the peak mitral valve velocity(Vmax),maximum pressure gradient difference(PGmax),and mean pressure gradi-ent difference(PGmean)between the observation group and the control group at 1,3,and 6 months after surgery.There was no statistically significant difference in creatine kinase isoenzyme(CK-MB)and N-terminal precursor brain natriuretic peptide(NT-proBNP)between the observation group and the control group at 1,3,and 6 months after surgery(P>0.05).There was no statistically significant difference in the incidence of postoperative complica-tions between the observation group and the control group(P>0.05).Conclusion The preservation of the mitral valve subvalvular structure and mitral membrane replacement surgery improved patient cardiac function,while there was no significant difference in mitral valve orifice blood flow parameters and complications compared with surgery without preservation of the mitral valve subvalvular structure.

Due to the limitations of current anti-HBV therapies, the HBV core (HBc or HBcAg) protein assembly modulators (CpAMs) are believed to be potential anti-HBV agents. Therefore, discovering safe and efficient CpAMs is of great value. In this study, we established a HiBiT-based high-throughput screening system targeting HBc and screened novel CpAMs from an in-house marine chemicals library. A novel lead compound 8a, a derivative of the marine natural product naamidine J, has been successfully screened for potential anti-HBV activity. Bioactivity-driven synthesis was then conducted, and the structure‒activity relationship was analyzed, resulting in the discovery of the most effective compound 11a (IC₅₀ = 0.24 μmol/L). Furthermore, 11a was found to significantly inhibit HBV replication in multiple cell models and exhibit a synergistic effect with tenofovir disoproxil fumarate (TDF) and IFNa2 in vitro for anti-HBV activity. Treatment with 11a in a hydrodynamic-injection mouse model demonstrated significant anti-HBV activity without apparent hepatotoxicity. These findings suggest that the naamidine J derivative 11a could be used as the HBV core protein assembly modulator to develop safe and effective anti-HBV therapies.

Objective To observe the feasibility of Fourier ring correlation(FRC)for measuring the overall resolution of ultrasonic microvascular images.Methods Liver contrast-enhanced ultrasound(CEUS)images of 1 patient with suspected hepatic hemangioma(dataset 1)were processed with singular value decomposition(SVD)filter(dataset 2)and Frangi filter(dataset 3),respectively.Three ROI were selected on CEUS image in each dataset,and the signal-intensity curves were drawn,and local resolution of CEUS image in each dataset was measured using full width at half maxima(FWHM)method.Then the above datasets were divided into odd frame subset and even frame subset,respectively,which were converted into frequency domain using fast Fourier transform.FRC curves were generated to calculate the overall resolution of each kind images.Results The signal-to-noise ratio(SNR)of CEUS images in dataset 1,2,3 was(19.94±2.33),(30.36±0.78)and(69.52±16.38)dB,respectively,the local resolution was(4.07±9.82),(1.53±0.04)and(1.27±0.06)mm,both successively increased(all P＜0.05).The overall resolution of CEUS images in dataset 1,2,3 was 2.07,0.91 and 0.51 mm,respectively.Conclusion FRC was feasible for measuring the overall resolution of ultrasonic microvascular images.
