Although symptomatic treatment is widely applied in clinical practice， it is often regarded as a relatively low-level therapeutic method. Based on Traditional Chinese Medicine （TCM） state theory， the macroscopic， mesoscopic， and microscopic characterization parameters of TCM symptomatology are horizontally integrated， the full life cycle of states （pre-disease， incipient disease， manifest disease， post-disease） is vertically covered， and the cognitive system of "symptoms" is reconstructed from multiple dimensions. Accordingly， the application approach of symptomatic treatment at different state stages is proposed： implementing preventive intervention in the pre-disease state， strengthening the interception of disease progression in the incipient disease state， regulating dynamic development and treatment in the manifest disease state， and formulating a staged diagnosis and treatment strategy which focuses on functional rehabilitation in the post-disease state.

BACKGROUND:It has been demonstrated that osteoclast activation plays an important role in skeletal system-related diseases.The mechanism of regulation of osteoclast activation by extracellular vesicles carrying non-coding RNA has not been fully elucidated. OBJECTIVE:To review and summarize relevant literature in and outside China,and to review the regulation of osteoclast activation by different non-coding RNAs in extracellular vesicles in different diseases,so as to provide a certain direction for subsequent research. METHODS:"Non-coding RNA,miRNA,lncRNA,circRNA,snoRNA,osteoclasts,extracellular vesicles,exosome,microparticle,apoptotic bodies"were used as search terms to search the databases of CNKI,WanFang,and VIP."Extracellular vesicles,exosome,microparticle,apoptotic bodies,non-coding RNA,miRNA,lncRNA,circRNA,snoRNA,osteoclast"were used as search terms to search PubMed.Finally,71 articles were included. RESULTS AND CONCLUSION:(1)The activation of osteoclasts is affected by many factors,among which the specific mechanism of non-coding RNA regulating osteoclast activation is not clear.(2)Extracellular vesicles can be secreted by osteoblasts,bone marrow mesenchymal stem cells,tumor cells and other cells.As a carrier of intercellular communication,extracellular vesicles can carry non-coding RNA to regulate osteoclast activation.(3)In the current studies on the regulation of osteoclast activation by extracellular vesicles carrying non-coding RNA,most of the diseases are osteoporosis,followed by tumor bone metastasis,and most types of non-coding RNA are miRNA.(4)There are relatively few studies on the regulation of extracellular vesicles carrying lncRNA and circRNA and snoRNA on osteoclast activation,and the regulatory mechanism is mainly ceRNA mechanism.(5)In conclusion,an in-depth study of the regulatory mechanism of extracellular vesicles carrying non-coding RNA on osteoclast activation is helpful to find key targets for the treatment of skeletal system-related diseases.

The correspondence between prescription and syndrome is the advantage and characteristic of traditional Chinese medicine(TCM)treatment.However,the pathogenesis of clinical diseases is complex and the condition is changeable,and the clinical application is difficult to achieve the maximum effect under the existing cognition of the correspondence between prescription and syndrome.In this paper,the five categories of physiological characteristics,pathological characteristics,constitution,syndrome,and disease of the longitudinal classification of"TCM state"are introduced into the correspondence of prescription and syndrome.Under the vertical perspective of"TCM state",the theoretical connotation of the correspondence between prescription and syndrome is interpreted as"correspondence between prescription and state",namely correspondence of"prescription-physiological characteristics",correspondence of"prescription-pathological characteristics",correspondence of"prescription-constitution",correspondence of"prescription-syndrome",and correspondence of"prescription-disease".It is hoped to accurately grasp the corresponding connotation of the correspondence between prescription and syndrome,in order to deepen the clinical thinking mode of TCM.

Based on the"You Gu Wu Yun"theory in traditional Chinese medicine(TCM),this paper believes that"Gu"in"You Gu Wu Yun"is extended to"state"from the perspective of"TCM state".In order to avoid the adverse reactions of TCM,the macro,meso,and micro three views should be used together,and macro,meso,and micro parameters should be integrated.We should also carefully identify the physiological characteristics,pathological characteristics,constitution,syndrome,and disease of human body by combining qualitative and quantitative method,highlighting the relationship between the prescription and the"state".The correspondence between prescription and the"state"will reduce the risk of adverse reactions of TCM.In this paper,we hope to focus on the guiding role of the"You Gu Wu Yun"theory in TCM research,to give full play to the characteristics and advantages of TCM,and to dialectically treat the role of TCM.

In the context of the complex and ever-changing spectrum of diseases, the traditional Chinese medicine compatibility of prescription and drugs is no longer able to fully meet the needs of clinical diagnosis and treatment. Therefore, this article is based on the diagnosis and treatment model of the combination of disease, syndrome, and symptom, combined with the development achievements of Western medicine, and explores the principles of formulating traditional prescriptions based on the combination of chief, deputy, assistant, and envoy. This article proposes a formulation principle of composing prescriptions with the diagnosis of syndrome as the chief, the diagnosis of disease as the deputy, the treatment of symptoms as the assistant, and the harmonization of medicine as the envoy. This forms a treatment plan with the core link of syndrome differentiation and treatment, disease differentiation and treatment, symptomatic treatment, detoxification, and efficacy enhancement. The purpose of this article is to address the current clinical challenges such as an increasing disease spectrum and the complexity of syndrome patterns and symptom clusters. It aims to provide new insights into traditional Chinese medicine clinical treatment plans and herbal formulation strategies, with the ultimate goal of improving the clinical effectiveness of traditional Chinese medicine.

Objective: To investigate the molecular typing and drug resistance of Salmonella in market-sold raw livestock meats in Shaoxing City, Zhejiang Province, so as to provide the basis for the prevention and control of drug-resistant Salmonella. Methods: Salmonella isolates were detected and serotyped from raw livestock meat samples collected from supermarkets, agricultural markets and restaurants in Shaoxing City between March and November 2023. Molecular typing was performed using pulsed-field gel electrophoresis (PFGE) and multilocus sequence typing (MLST). Antibiotic resistance phenotypes and resistance gene analyses were conducted using broth microdilution method and whole genome sequencing. Results: A total of 34 Salmonella isolates were detected from 329 samples and the positive rate was 10.33%. There were 14 serotypes, with S. Rissen (9 isolates, 26.47%) and S. London (8 isolates, 23.53%) being dominant. PFGE typing revealed 31 band patterns and 23 banding pattern clusters of Salmonella, and the similarity ranged from 30.80% to 100.00%, without dominant band patterns. MLST identified 15 sequence typing (ST) types, and S. Rissen were all ST469 and S. London were all ST155. Salmonella strains exhibited high levels of resistance to tetracycline (44.12%) and ampicillin (35.29%). Thirteen resistance patterns were identified, with 8 multidrug resistant patterns (29.41%). There were 8 classes of 14 resistance genes, with aminoglycoside resistance gene aac(6' )-Iaa found in 100.00% of the strains. The highest concordance rate between the resistance phenotype and gene was observed for phenicol antibiotics (97.06%), while there was no concordance between the quinolone resistance phenotype and genes. Conclusions S. Rissen and S. London are the predominant serotypes in market-sold raw livestock meats in Shaoxing City. The PFGE band types of the Salmonella isolates show polymorphism distribution, and MLST are mainly ST469 and ST155. The isolates have high levels of resistance to tetracycline and ampicillin, manifesting multidrug resistance.

Scars are classified into 5 types:Superficial scars,hypertrophic scars,atrophic scars,depressed scars,and keloid.These types are primarily characterized by abnormal production of fibroblasts and collagen,as well as the disorderly arrangement of connective tissue.Laser treatment for scars involves the coordinated activation of various signaling pathways and cytokines.However,the exact pathological mechanism for scar formation remains unclear,leading to a lack of radical treatment.Recently,laser treatment has gained popularity as a new minimally invasive approach for scar treatment.The emergence of new theories such as fractional,picosecond laser,and laser-assisted drug delivery has led to continuous advance in laser treatment.Up to now,it has been developed numerous novel treatments,including combined with drug,physical,and other treatments,which have shown superior therapeutic effects.In order to optimize laser treatment in the future,it is crucial to combine new materials with postoperative care.This will help clinicians develop more comprehensive treatment strategies.Therefore,it is important to explore treatment options that have broader applicability.

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.

Objective: To explore the preventive effect of nicotinamide (NAM) on cleft palate induced by all-trans retinoic acid (RA), to provide research evidence for the prevention of cleft palate. Methods : The mouse cleft palate model was induced by intragastric administration of 70 mg/kg all-trans retinoic acid at embryonic day 10.5 (E10.5) in the control group. The mouse cleft palate model was treated by caudal vein injection of 20 mg/kg NAM at E8.5 to E13.5 in the experimental group (1). The cleft palate model was treated by caudal vein injection of 40 mg/kg NAM at E8.5-E13.5 in the experimental group (2). The cleft palate of fetal rats was observed by laparotomy on E16.5 and statistically analyzed. Annexin V-FITC/PI double staining was used to detect the apoptosis of mouse embryonic palatal mesenchyme (MEPM) cells treated with RA 1 μmol/L (RA 1 group), NAM 200 μmol/L (NAM 200 group), and both NAM 200 μmol/L and RA 1 μmol/L (NAM 200+RA 1 group) for 24 hours by flow cytometry and the apoptosis rate in groups were compared. Culture without RA or NAM was used as a control. Results : The cleft palate rate in the control group was 98%. The cleft palate rate in experimental group (1) was 87%. There was no significant difference between groups (P>0.05). The cleft palate rate in the experimental group (2) was 63%, compared with the control group, there was a significant difference (P<0.01). The cell apoptosis rate was 16.53%±2.89% in the CONTROL group. The cell apoptosis rate was 22.9%±1.85% in the RA 1 group, which was a significant increase compared with the CONTROL group (P<0.01). The apoptotic rate of the NAM 200 group was 9.23%±1.39%, which was a significant decrease compared with NA 1 group (P<0.01). The apoptosis rate of the NAM 200+RA 1 group was 14.9%±7.67%, which was a significant decrease compared with the RA 1 group (P<0.01). Conclusion NAM can prevent cleft palate. 40 mg/kg nicotinamide during pregnancy is an effective concentration for the prevention of RA-induced cleft palate. The mechanism by which NAM prevents cleft palate may be that NAM inhibits RA-induced apoptosis of MEPM cells.

OBJECTIVE: To summarize the regulatory effect of non-coding RNA (ncRNA) on type H vessels angiogenesis of bone. METHODS: Recent domestic and foreign related literature about the regulation of ncRNA in type H vessels angiogenesis was widely reviewed and summarized. RESULTS: Type H vessels is a special subtype of bone vessels with the ability to couple bone formation. At present, the research on ncRNA regulating type H vessels angiogenesis in bone diseases mainly focuses on microRNA, long ncRNA, and small interfering RNA, which can affect the expressions of hypoxia inducible factor 1α, platelet derived growth factor BB, slit guidance ligand 3, and other factors through their own unique ways of action, thus regulating type H vessels angiogenesis and participating in the occurrence and development of bone diseases. CONCLUSION At present, the mechanism of ncRNA regulating bone type H vessels angiogenesis has been preliminarily explored. With the deepening of research, ncRNA is expected to be a new target for the diagnosis and treatment of vascular related bone diseases.
