In recent years， the incidence of pulmonary nodules has kept rising. To give full play to the advantages of traditional Chinese medicine （TCM） in the treatment of pulmonary nodules and identify the breakthrough points of integrating TCM with Western medicine， the China Association of Chinese Medicine organized medical experts in TCM and western medicine to carry out in-depth discussion regarding this disease. The discussion encompassed the modern medical advances， TCM theories of etiology and pathogenesis， the role and advantages of TCM in the whole course management of pulmonary nodules， contents and methods of research on pulmonary nodules， and science popularization work， aiming to provide a reference for clinical practice and scientific research. After discussion， the experts concluded that the occurrence of pulmonary nodules was rooted in the deficiency of the lung and spleen and triggered by phlegm dampness， blood stasis， and Qi stagnation. TCM can treat pulmonary nodules by controlling and reducing nodules， improving physical constitution， ameliorating multi-system nodular diseases， reducing anxiety and avoiding excessive diagnosis and treatment， and serving as an alternative for patients who are unwilling or unfit for surgical treatment. At present， the optimal diagnosis and treatment strategy for pulmonary nodules has not been formed， which needs to be further studied from multiple perspectives such as clinical epidemiology， biology， and evidence-based medicine. The primary task of current research is to find out the advantages， effective prescriptions， and target populations and determine the effective outcomes of TCM in the treatment of pulmonary nodules. At the same time， basic research should be carried out to explore the etiology and biological behaviors of pulmonary nodules. The expert consensus on the diagnosis and treatment of pulmonary nodules with integrated TCM and Western medicine needs to be continuously revised to guide clinicians to conduct standardized， scientific， and accurate effective diagnosis and treatment.

Objective: To explore the correlation between Diabetes Complication Severity Index(DCSI), C-reactive protein/albumin ratio(CAR) and death in patients with diabetic foot ulcer(DFU) and to clarify their predictive value for all-cause death in DFU patients. Methods: Retrospectively analyzed the clinical data of 354 DFU patients who were treated in the Endocrinology Department of the First Affiliated Hospital of Anhui Medical University from July 2019 to December 2022. Based on survival status during follow-up, patients were divided into a survival group(n=268) and a death group(n=86). Univariate and multivariate Cox regression analyses were used to identify risk factors for all-cause death in DFU patients. Receiver operating characteristic(ROC) curves were plotted to evaluate the predictive value of DCSI, CAR, and their combination for all-cause death in DFU patients. Kaplan-Meier curves were used to explore the impact of different DCSI and CAR levels on survival in DFU patients. Results: Univariate Cox regression analysis showed that older age, history of hypertension, higher Wagner classification levels, and elevated levels of CRP, Scr, FDP, DCSI score, and CAR were associated with a higher risk of death in DFU patients(P<0.05). Higher levels of HGB, HCT, ALB, or eGFR were associated with a lower risk of death. Patients receiving combined insulin and oral hypoglycemic medication had a lower risk of death compared to those receiving only insulin therapy(P<0.05). Multivariate Cox regression analysis indicated that older age, higher levels of Scr, DCSI, and CAR were independent risk factors for all-cause death in DFU patients, while higher levels of ALB and combined insulin and oral hypoglycemic therapy were protective factors. ROC curve analysis showed that the AUC values for DCSI, CAR, and their combination were 0.652, 0.633, and 0.686, respectively. Kaplan-Meier curve analysis revealed that patients with high DCSI scores(≥4.5) had a lower survival rate compared to those with lower DCSI scores(<4.5). Similarly, patients with high CAR levels(≥0.124) had a lower survival rate compared to those with lower CAR levels(<0.124). Conclusion High levels of DCSI and CAR are independent risk factors for all-cause death in DFU patients. DCSI, CAR, and their combination have predictive value for all-cause mortality in DFU patients.

In this report,we described a case of a clinical practice,in which the clinical pharmacists was involved in the treatment of a soft tissue sarcoma patient,who was diagnosed with mental disorders induced by regorafenib.The patient was complicated with hypoproteinemia,hepatic insufficiency,leukoencephalopathy and other diseases.Before the treatment,the patient's mental was normal.After continuous administration of regorafenib(40 mg,po,qd)for 5 days,the patient has a sudden loss of consciousness.Clinical pharmacists excluded the possibility of mental disorders caused by tumor brain metastases,exacerbation of leucoencephalopathy or hepatic encephalopathy and the drugs used together.They determined that mental disorders were likely to be related to the use of regorafenib through the association evaluation of adverse reactions.It was considered to be an adverse reaction induced by regorafenib.Therefore,regorafenib treatment was temporarily suspended and symptomatic treatment was given.After 5 days,the patient's mental state improved.In addition,clinical pharmacists monitored the patient for symptomatic treatment,and provided appropriate antitumor drug treatment recommendations based on evidence-based evidence.This case suggests that the clinical use of regorafenib should be vigilant against mental disorders adverse reactions,do a good job of pharmaceutical care,and timely drug analysis and symptomatic treatment after adverse reactions.

AIM:To analyze the compliance rate and possible influencing factors for blood concen-tration of meropenem in patients with central ner-vous system(CNS)infections,and to provide basis for optimizing the administration of meropenem in the patients.METHODS:A retrospective analysis was performed in patients who were treated with meropenem and monitored the concentration(Cmin)from January 2021 to December 2022.The basic clinical data of the patients were recorded,and the achievement of meropenem blood concentration was counted.Univariate and binary logistic regres-sion analysis were used to analyze the influencing factors for the e substandard steady-state blood trough concentration of meropenem.The ROC curve was drawn to predict the clinical characteris-tics.RESULTS:Forty-five cases were included.The median Cmin of meropenem was 4.14(0.82,16.29)mg/L,and 51.11％reached the target range with 4 mg/L.Binary logistic regression analysis showed that serum creatinine value and using mannitol were risk factors for the substandard steady-state blood trough concentration of meropenem(P＜0.05).When serum creatinine value was less than 84 μmol/L,the area under the ROC curve was the largest(0.916),the sensitivity was 0.783,the speci-ficity was 0.955,and the Youden index was 0.738.CONCLUSION:The Cmin compliance rate of merope-nem blood concentration in patients with CNS in-fection is low,especially in patients with hyperfunc-tion of kidney and those who using mannitol.It is necessary to conduct drug concentration monitor-ing to optimize the administration of meropenem in patients with CNS infection.

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.

Malignant tumors are one of the main causes of human death worldwide and pose a serious threat to human health. The current treatment methods are mainly the combination of chemotherapeutics， surgery， radiotherapy， or hormone therapy. The treatment process has limitations such as multidrug resistance， non-selective targeting of cancer cells， and drug toxicity. With the development and application of traditional Chinese medicine （TCM）， Chinese medicine has the characteristics of multi-angle and multi-mechanism coordination and slight toxic and side effects. It can effectively inhibit tumor proliferation， differentiation， and metastasis， and avoid drug resistance， serving as the focus of current tumor treatment research. Hedysari Radix， one of the genuine medicinal materials in Gansu province， is a tonic Chinese medicine with a wide range of pharmacological effects such as anti-inflammation， immune regulation， anti-oxidation， prevention and treatment of diabetic complications. In the majority of the ancient works on herbs of the past dynasties， Hedysari Radix was included under the item of Astragali Radix and used as Astragali Radix. Hedysari Radix is superior to Astragali Radix in enhancing immunity， scavenging free radicals， and resisting liver fibrosis. Studies have found that the effective components of Hedysari Radix have a prominent anti-tumor effect and a significant inhibitory effect on various malignant tumors such as liver cancer， bladder cancer， gastric cancer， breast cancer， and colorectal cancer. They can also combine with clinical anti-cancer drugs to reduce the toxic and side effects of chemotherapy drugs and improve the tolerance of patients during chemotherapy. On the basis of current research， this study summarized the mechanism of Hedysari Radix active components in inducing cell apoptosis， blocking cell cycle， inhibiting tumor cell proliferation， migration， and invasion， regulating micro mRNA （miRNA）， inducing cell autophagy， enhancing immune regulation， as well as reducing toxicity and enhancing efficiency and sensitization with clinical chemotherapeutics， and systematically explained the anti-tumor mechanism of Hedysari Radix active components， aiming to provide a basic reference for the further exploration of the anti-tumor mechanism of Hedysari Radix and the further development and utilization of its effective components.

Most hospitalized patients infected with coronavirus disease 2019 (COVID-19) are in severe or critical condition, and malnutrition is a key factor contributing to adverse outcomes. The basic principles of medical nutrition therapy have been determined in the recently released tenth edition of the National Diagnosis and Treatment Protocol. The principles have promoted nutritional risk assessment, emphasized the preferred method of enteral nutrition, and recommended the daily intake of calories at 25 to 30 kcal/kg and protein at > 1.2g/kg. Parenteral nutrition should be also added when necessary. Based on the above principles, Beijing Hospital has refined the medical nutrition therapy measures to facilitate the implementation in clinical practice, in order to improve healthcare quality and decrease the mortality in COVID-19 patients.
