Osteoscarcopenia (OS) is a common degenerative syndrome in the elderly, which is caused by a decrease in both bone and muscle mass during the aging process, leading to osteoporosis and sarcopenia, a decrease in body balance, and a risk of falls and fractures, posing a serious threat to the quality of life and lifespan of the elderly. Osteoskeletal dystrophy increases with age, and its occurrence is higher in females than that in males. At present, there is no unified diagnostic standard, making it impossible to achieve early detection and intervention. The commonly used diagnostic methods include quantitative computed tomography (CT), magnetic resonance imaging (MRI), dual energy X-ray absorptiometry (DXA), muscle mass bioelectrical impedance analysis (BIA), as well as daily gait speed (UGS), short physical performance battery (SPPB), timed start test (TUG), and biochemical evaluation indicators to improve early diagnosis and screening. Due to the fact that both bones and muscles belong to the motor system, osteoporosis and sarcopenia share common pathogenic factors in genetics, endocrine, paracrine, and fat infiltration, which interact and regulate each other, inducing the occurrence of osteoscarcopenia. Osteoporosis and sarcopenia, two age-related diseases, share the same pathogenesis and regulatory pathways, as well as common drug targets. For example: somatostatin α‑actin-3, peroxisome proliferator activated receptor γ coactivation factor-1α (PGC-1α), myocyte enhancer factor-2 (MEF2C), sterol regulatory element binding transcription factor 1 (SREBF1), protoadhesion 7 (PCDH7) and methyltransferase like 21C (METTL21C), osteocalcin and bone derived bone factor gap junction connexin 43 (Cx43), growth hormone (GH), sex hormones, and diseases (such as tumors, diabetes, polycystic ovary syndrome, cardiovascular disease, anemia, disability, inflammatory disease), aging, nutrition, and poor living habits are closely related to osteosarcopenia. Osteoporosis is characterized by low bone mass and microstructural degeneration of bone tissue, while sarcopenia is characterized by loss of muscle mass, strength, and function, both of which often coexist in the elderly population. Exercise regulates muscle and skeletal cytokines such as myostatin (MSTN) and irisinβ‑aminoisobutyric acid (BAIBA), brain derived neutrophil factor (BDNF), interleukin, prostaglandin E2, Wnt, osteocalcin (OCN), and transforming growth factor‑β (TGF‑β) and receptor activator of NF-κB ligand (RANKL) interfere with each other to prevent and treat osteoscarcopenia. Wnt/β‑catenin signaling pathway can simultaneously regulate the growth and metabolism of bones and muscles, and promote osteoblast proliferation, maturation, and mineralization by increasing OPG/RANKL, which is beneficial for bone mass increase and induces proliferation of muscle satellite cells, stimulating and promoting increased muscle synthesis. NF‑κB pathway is the main regulatory factor for inflammation mediated muscle atrophy. Meanwhile, NF‑κB DNA can participate in RANKL inducing osteoclast differentiation in bone tissue, thereby reducing bone mass. Although exercise and nutrition can improve the symptoms of osteoporosis, they cannot be completely cured, and there are no specific drugs in clinical practice that can cure sarcopenia. Because osteoscarcopenia has a common crosstalk mechanism in the aging process, it is of great significance to prevent osteoscarcopenia by improving bone mass and muscle content through exercise, nutrition, and medication.

Objective To investigate the clinical efficacy and safety of single-port thoracoscopic surgery for elderly patients with non-small cell lung cancer(NSCLC).Methods The clinical data of 93 patients with NSCLC who underwent thoracoscopic lobectomy or segmentectomy was collected,the patients were divided into uniportal operation group(40 cases,received single-port thoracoscopic surgery)and single-operation port operation group(53 cases,received single-operation port thoracoscopic surgery)according to the operation methods.The operation time,the amount of blood loss,the number of lymph node dissection,chest drainage volume 3 days after surgery,duration of indwelling drainage tube,postoperative hospital stay,visual analogue scale(VAS)score of postoperative pain,and incidence of postoperative complications of patients between the two groups were compared.The cumulative survival rate between the two groups was compared.Results The operation were successfully completed in both groups.There was no statistically significant difference in terms of operation time,the amount of blood loss,the number of lymph node dissection,chest drainage volume 3 days after surgery,duration of indwelling drainage tube,or postoperative hospital stay of patients between the two groups(P>0.05).There was significant difference in VAS score of postoperative pain of patients between the two groups(P<0.05).There was no early death within 1 months after surgery in both groups.There was no significant difference in the incidence of complications between the two groups(P>0.05).After 4 to 30 months of follow-up,there was no significant difference in the cumulative survival rate between the two groups(P>0.05).Conclusion Single-port thoracoscopic lobectomy or segmentectomy for elderly patients with NSCLC has high safety and feasibility,with less trauma,faster recovery and less postoperative pain.

Objective:To explore the differential impact of the alignment between service capability and job satisfaction on job performance among primary general practitioner,and to provide a reference for enhancing their job performance.Methods:A survey was conducted with 620 primary general practitioner using questionnaires.The relationships among service capability,job satisfaction,and job performance were analyzed using polynomial regression and response surface analysis methods.Results:Under the condition of"service capability—job satisfaction alignment,"compared to the scenario of"low service capability—low job satisfaction,"primary general practitioner with"high service capability—high job satisfaction"demonstrated significantly higher job performance(a1=0.875,P＜0.001;a2=-0.068,P＞0.05).In the misalignment condition,compared to"low service capability—high job satisfaction,"those with"high service capability—low job satisfaction"also showed higher job performance(a3=0.265,P＜0.001;a4=-0.064,P＞0.05).Conclusion:Both service capability and job satisfaction significantly influence job performance among primary general practitioner,with service capability being a key factor for achieving high work performance.It is essential to enhance the service capability of primary general practitioner and adopt multiple strategies to improve job satisfaction,thereby effectively boosting work performance.

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.

Purpose: Gastric cancer (GC) is the second most lethal cancer globally and is associated with poor prognosis. Fatty acid-binding proteins (FABPs) can regulate biological properties of carcinoma cells. FABP5 is overexpressed in many types of cancers; however, the role and mechanisms of action of FABP5 in GC remain unclear. In this study, we aimed to evaluate the clinical and biological functions of FABP5 in GC. Materials and Methods: We assessed FABP5 expression using immunohistochemical analysis in 79 patients with GC and evaluated its biological functions following in vitro and in vivo ectopic expression. FABP5 targets relevant to GC progression were determined using RNA sequencing (RNA-seq). Results: Elevated FABP5 expression was closely associated with poor outcomes, and ectopic expression of FABP5 promoted proliferation, invasion, migration, and carcinogenicity of GC cells, thus suggesting its potential tumor-promoting role in GC. Additionally, RNA-seq analysis indicated that FABP5 activates immune-related pathways, including cytokinecytokine receptor interaction pathways, interleukin-17 signaling, and tumor necrosis factor signaling, suggesting an important rationale for the possible development of therapies that combine FABP5-targeted drugs with immunotherapeutics. Conclusions These findings highlight the biological mechanisms and clinical implications of FABP5 in GC and suggest its potential as an adverse prognostic factor and/or therapeutic target.

Objective:To evaluate the effect of botulinum toxin type A (BTXA) on flap surgery in animal models.Methods:Nine databases (PubMed, Cochrane Library, Ovid, Web of Science, Embase, Scopus, CBM, CNKI, and WANFANG database) were searched for published literature comparing the effects of BTXA (BTXA group) versus saline or no treatment (control group) on flap operation in animal models from January 1979 to March 2022. The literature was screened according to inclusion and exclusion criteria. Indicators included flap survival rate, blood flow and vascular endothelial growth factor (VEGF) expression level after surgery. The subjects were divided into pre-operation injection group and intraoperation injection group according to the intervention timing, and were divided into random flap group and axial flap group according to the type of flaps, and subgroup analysis was conducted respectively. Review Manager (RevMan) 5.3 software and Stata 15.1 software were used for all statistical analysis.Results:A total of 603 animals from 19 studies were included after rigorous inclusion and exclusion screening. Compared with control group, BTXA group revealed a significantly higher flap survival rate [mean difference ( MD)=15.65%, 95% CI: 13.11%-18.19%, Z=12.08, P<0.001], blood flow [standardized mean difference ( SMD)=1.96, 95% CI: 1.39-2.54, Z=6.71, P<0.001] and VEGF expression (at mRNA level: SMD=6.01, 95% CI: 0.89-11.13, Z=2.30, P=0.020; at protein level: SMD=3.44, 95% CI: 2.44-4.43, Z=6.73, P<0.001). Subgroup analysis showed that the flap survival rate of the pre-operation injection group ( MD=21.54%, 95% CI: 16.07%-27.01%, Z=7.71, P<0.001) was significantly higher than that of the intraoperative injection group ( MD=9.40%, 95% CI: 6.79%-12.00%, Z=7.07, P<0.001). The flap survival rate of the random flap group ( MD=20.87%, 95% CI: 16.67%-25.07%, Z=9.73, P<0.001) was significantly higher than that of the axial flap group ( MD=13.11%, 95% CI: 8.91%-17.31%, Z=6.12, P<0.001). Conclusion:BTXA assisted flap surgery may have positive effects on the survival rate, blood flow and VEGF expression in animal models. In addition, injection timing and flap type may also be important factors in the effect of BTXA on flap surgery.
