ObjectiveTo investigate the inhibitory effect of Biejia Decoction Pill on the proliferation， migration， and aerobic glycolysis of hepatocellular carcinoma （HCC） using cell experiments， as well as related mechanisms. MethodsHuman liver cancer cell line Huh7 was selected， and Sprague-Dawley rats were randomly divided into blank serum group， inhibitor group， and high-， middle-， and low-dose Biejia Decoction Pill groups. Rat serum containing the drug was prepared for the incubation of Huh7 cells. CCK8 assay and scratch assay were used to explore the effect of Biejia Decoction Pill on the proliferation and migration of HCC cells； glycolytic rate-limiting enzymes and metabolites were measured to explore the effect of Biejia Decoction Pill on aerobic glycolysis of liver cancer cells； RT-qPCR and Western blot were used to explore the effect of Biejia Decoction Pill on the mRNA expression， related proteins， and phosphorylation of the protein kinase B （AKT）/mammalian target of rapamycin （mTOR） signaling pathway. A one-way analysis of variance was used for comparison between multiple groups， and the least significant difference t-test or the Dunnett’s T3 test were used for further comparison between two groups. ResultsCompared with the blank serum group， the Biejia Decoction Pill groups had significant reductions in OD value， migration rate during different periods of time， glycolytic rate-limiting enzymes （hexokinase， phosphofructokinase， pyruvate kinase）， and glycolytic metabolites （pyruvate， lactic acid， ATP） （all P<0.05）. RT-qPCR results showed that compared with the blank serum group， the high-， middle-， and low-dose Biejia Decoction Pill groups had a significant reduction in the mRNA expression level of mTOR， and the high- and low-dose Biejia Decoction Pill groups had a significant reduction in the mRNA expression level of AKT （all P<0.05）. Western blot results showed that compared with the blank serum group， the high-， middle-， and low-dose Biejia Decoction Pill groups had significant reductions in the expression levels of mTOR-related proteins and phosphorylated proteins， and the high- and middle-dose Biejia Decoction Pill groups had significant reductions in the expression levels of AKT-related proteins and phosphorylated proteins （all P<0.05）. ConclusionThis study preliminarily verifies that the serum containing Bijia Decoction Pill can inhibit the aerobic glycolysis of human hepatoma Huh7 cells， thereby inhibiting their proliferation and migration， possibly by inhibiting the expression of the proteins related to the AKT/mTOR signaling pathway.

Objective To analyze the application of flipped classroom in the practical teaching of rehabilitation assessment courses for rehabilitation therapy majors,and to explore a new teaching method for rehabilitation therapy.Methods Eighty students majoring in rehabilitation therapy from the Department of Rehabilitation Medicine of Guangzhou Xinhua University in grade 2020 were selected as the research objects.They were assigned into observation group or control group according to the random number table method,with 40 cases in each group.The observation group adopted the flip classroom teaching mode,and the rehabilitation assessment course teaching based on flipped classroom was carried out,while the control group adopted the traditional teaching mode.The students'theoretical and operational assessment results,teaching effect,and teaching model satisfaction were analyzed.Results No statistically significant differences were found in theoretical test scores between the two student groups(by gender/course).The students in the observation group had higher theoretical scores[(80.25±11.65 vs 72.50±14.28)score].The observation group showed significantly higher satisfaction scores than the control group across all three dimensions:classroom learning enthusiasm,teacher-student interaction,and overall teaching satisfaction.(P<0.05).Conclusion The application of flipped classroom in the rehabilitation therapy teaching is helpful to improve the professional theoretical level of students,and to a certain extent,it is beneficial to improve the professional level of teachers.

Natural herbs demonstrate significant therapeutic potential in managing chronic and complex diseases; however, their clinical application faces limitations due to low bioavailability, instability, toxicity, and herb-drug interactions. Furthermore, insufficient standardized evidence and global acceptance impede their widespread adoption. Liposomes, nanocarriers consisting of a phospholipid bilayer enclosing an aqueous core, present a promising approach for enhancing the pharmacokinetics and therapeutic efficacy of herbal compounds. These adaptable systems can encapsulate both hydrophilic and hydrophobic agents, enabling targeted drug delivery and enhanced stability. Moreover, liposomes can be modified to carry diagnostic and imaging agents, enabling precise disease detection and monitoring. While liposomes offer potential as an innovative delivery technology for herbal remedies, their application in Traditional Chinese Medicine (TCM) remains relatively unexplored. TCM, with its holistic, energy-based approach to health and organ function, presents distinct challenges regarding formulation and delivery. This review examines the therapeutic potential of herbal medicines, emphasizing how liposomes address delivery challenges within the TCM framework. It also investigates the integration of TCM with Western medical practices, demonstrating how liposomal systems may bridge these approaches. The review analyzes key formulation techniques for TCM-loaded liposomes, particularly the microfluidic method, which demonstrates superior control over particle size and encapsulation efficiency compared to conventional methods. The analysis addresses barriers to integrating liposomal delivery systems with TCM, including physicochemical properties, scalability issues, and regulatory challenges. Finally, this review provides strategic recommendations for overcoming these obstacles and identifies future research directions to maximize the potential of liposomal technology in enhancing TCM therapies.

Objective:To investigate the intention to stay on among primary health care workers (PHWs) during the COVID-19 epidemics and its influencing factors.Methods:An online questionnaire survey was conducted among PHWs from 62 primary health institutions in 31 provinces, autonomous regions and municipalities across China selected by multi-stage whole cluster random sampling method between May and October 2022. According to the job position, the PHWs were divided into 5 categories: general practitioners (GPs), nurses, public health doctors, managers and support staff. Intention to stay was measured using the Chinese version of the Intention to Stay Questionnaire. Multiple linear regression model was used to analyze the influencing factors of the intention to stay in PHWs of different occupational categories, including personal factors, work factors, factors related to the COVID-19 and psychological reactions.Results:A total of 3 769 PHWs from 44 community health service centers, 18 township hospitals of 27 provinces/autonomous regions and 4 municipalities participated in this survey. The mean age of participants was (37.4±9.2) years, including 2 971(78.8%) women. The mean score of intention to stay of participants was 21.7±4.1. Compared with GPs, managers had lower intention to stay ( P=0.004). Age, female, in marriage, monthly income, years of primary care service, self-evaluation of unit support function, MSQ-SF score, and PA score were positively correlated with the score of intention to stay (all P<0.05), while PHQ-9 score, EE score, and DP score were negatively correlated with the score of intention to stay (all P<0.05). The MSQ-SF scores of all occupational categories were positively correlated with the scores of intention to stay (all P<0.01). In addition, among GPs, monthly income, years of service in primary care, self-evaluation of unit support function, and PA scores were positively correlated with the score of intention to stay (all P<0.05), while PHQ-9 scores and EE scores were negatively correlated with the score of intention to stay (all P<0.05). Among nurses, age, female gender, monthly income, self-evaluation of unit support function, and PA score were positively correlated with the score of intention to stay (all P<0.05), while EE scores and retention will score were negatively associated with ( P<0.001). Among public health doctors, in marriage was positively correlated with the score of intention to stay ( P=0.018). Among managers, DP score was negatively correlated with the score of intention to stay ( P=0.001). Among support staff, female gender, monthly income, years of primary care service, self-evaluation of unit support function, and PA scores were positively correlated with the score of intention to stay (all P<0.05), while EE score and DP score were negatively correlated with intention to stay (all P<0.05). Conclusions:The intention to stay of PHWs in China during the COVID-19 was at an intermediate level, which was affected by many factors. Among them, job satisfaction was positively correlated with the intention to stay of all occupational categories, and the influencing factors of different occupational categories have some variations.

Matrix metalloproteinase-28(MMP-28)is widely expressed in vertebrates and plays diverse biological roles,participating in the regulation of various pathophysiological processes in the body.Increased expression of MMP-28 has been observed in chronic obstructive pulmonary disease,pulmonary fibrosis,and other lung diseases.Studies have demonstrated that MMP-28 promotes chronic inflammation and tissue remodeling by regulating macrophage recruitment and M2 polarization,and is involved in the pathogenesis of lung diseases by promoting cell proliferation and epithelial-mesenchymal transition.This article provides a review of the relationship between the basic characteristics of MMP-28 and pulmonary diseases.

Neuropathic pain(NPP)is a recurrent and intractable pain syndrome,and microglial polarization is closely related to it.Recent studies have shown that after cell polarization,M1 pro-inflammatory and M2 anti-inflammatory types could be formed,and M1 and M2 microglial cells are involved in NPP through the modulation of inflammatory responses.The two types of microglial cells have different roles in NPP,just like a double-edged sword.M1 pro-inflammatory type plays an injurious role in NPP through the release of pro-inflammatory factors and noxious substances,whereas M2 anti-inflammatory type plays a protective role by secreting anti-inflammatory factors.In this article,the role of microglia polarization on NPP are reviewed.

Objective:To study the distribution of species type, biotype and genotype of human Brucella isolated and identified in Nanjing. Methods:A total of 89 strains of human Brucella were collected from microbiology laboratories of three sentinel hospitals in Nanjing from 2017 to 2022. The species type was identified using biological methods and Brucella nucleic acid detection (BCSP31-PCR and AMOS-PCR). Further biotyping of Brucella melitensis isolates was conducted by serological results of A and M factors. Meanwhile, genotype analysis was performed using multiple-locus variable number tandem repeat analysis (MLVA), multilocus sequence typing (MLST) and single nucleotide polymorphism (SNP). Results:From 2017 to 2022, 89 strains of Brucella isolated and identified in Nanjing were all Brucella melitensis. Among them, Brucella melitensis biotype 3 accounted for 82.02% (73/89), and biotype 1 accounted for 17.98% (16/89). MLVA typing showed that 89 strains of Brucella melitensis belong to the "Eastern Mediterranean" cluster and could be divided into 50 MLVA genotypes; among which panel 1 had 3 genotypes, namely Type 42 (84.27%, 75/89), Type 63 (8.99%, 8/89) and Type 43 (6.74%, 6/89). The results of MLST-9 and MLST-21 were both ST8, and the core genome multilocus sequence typing (cgMLST) classified 89 strains into 11 genotypes. SNP analysis revealed a total of 4 013 SNP loci, with SNPs ranging from 0 to 409 across different strains, involving 59 SNP genotypes. Conclusions:The human Brucella strains isolated and identified in Nanjing are all Brucella melitensis, mainly biotype 3. The MLVA cluster is the "Eastern Mediterranean" cluster. The traditional MLST-9 and MLST-21 typing results are all ST8 type, while cgMLST divides all the strains into 11 genotypes with higher resolution.
