Based on a review of clinical trial assessment indices for metabolic dysfunction-associated fatty liver disease （MAFLD） and the current status of traditional Chinese medicine （TCM） research， this article proposes a multi-dimensional， stratified， and operable clinical efficacy evaluation framework for TCM with reference to the features of MAFLD and the therapeutic effect of TCM. This system encompasses eight dimensions of liver histology， radiology， biochemical indicators， metabolic markers， anthropometry， TCM syndromes， patient-reported outcomes， and safety indicators， which are stratified according to research objectives and disease stages. This study further explores the implementation pathways for the standardization of syndrome evaluation， research design norms， and quality control， in order to provide methodological support for conducting high-quality TCM clinical research and promote the transition of TCM efficacy evaluation from “single indicators” to “multi-dimensional composite indicators”.

Objective To explore the feasibility of magnetic compression technique (MCR) in the treatment of severe single mid-ureteral stricture in a rabbit model. Methods After 10 female New Zealand rabbits were selected, the distal end of the right ureter was ligated with silk thread. Two weeks after the operation, when the right ureter was dilated, the mid-ureter was ligated again with silk thread to create a severe single mid-ureteral stricture animal model. Longitudinal incisions were made at the upper and lower ends of the ligation site, and cylindrical NdFeB magnets with central holes (sub-magnets and main magnets) were placed to anastomose and recanalize the mid-ureteral stricture. The magnets were adjusted to the appropriate position to automatically align and attract each other. The longitudinal incision sites of the ureter were sutured with 6-0 Prolene thread, and the abdominal cavity was closed layer by layer. The operation time was recorded. X-ray films were taken every two days to confirm the position of the magnets and record the time of magnet detachment. Three weeks after the operation, the anastomotic specimens were obtained, and the formation of the anastomosis was evaluated with gross observation and histological staining. Results Two weeks after ligation, all experimental rabbits showed obvious dilation of the right ureter. The mid-ureteral ligation and placement of the male and female magnets were successfully completed in all 10 experimental rabbits, with an operation time of (24.00±5.15)minutes. The male and female magnets attracted each other well. X-ray examination showed that the magnets detached and entered the distal ureter (14.0±1.9) days after magnetic compression. The recanalization of the severe single mid-ureteral stricture was successfully achieved. The gross specimens and histological examination of the anastomosis showed that the anastomosis remained patent and the mucosal healing was good. All experimental rabbits survived well after the operation without serious complications. Conclusion MCT provides a new idea and novel method for the treatment of mid-ureteral stricture. This study confirmed the feasibility of this technique in treating severe single mid-ureteral stricture in a rabbit model. The operation is relatively simple and has potential for clinical application.

B lymphocytes (B cells) play a complex and paradoxical role in tumorigenesis. They can recognize tumor-associated antigens, present these antigens to T cells, and produce antibodies that directly target and eliminate tumor cells. This makes B cells a potentially powerful ally in combating cancer. However, B cells also exhibit immunosuppressive functions, secreting cytokines like IL-10 or generating tumor-promoting antibodies that dampen the anti-tumor immune response, and some tumor cells have even been shown to exploit B cells to promote their growth and metastasis. This dual nature of B cells presents both opportunities and challenges for tumor immunotherapy. In this review, we summarize the mechanisms underlying the multifaceted functions of B cells and their current applications in cancer immunotherapy. Furthermore, we also explore the key issues and future directions in this field, emphasizing the need for further research to fully harness the anti-tumor potential of B cells in the fight against cancer.

Objective To analyze the efficacy and adverse reactions of donepezil in the treatment of patients with a continuous disease spectrum of Alzheimer's disease(AD)with pharmacogenomics.Methods Seventy-two patients who took donepezil therapy at the time of initial molecular pa-thology diagnosis of AD continuous disease spectrum in Chinese PLA General Hospital from Jan-uary 2022 to January 2023 were recruited.Cells from the oral buccal mucosa were collected,and MassARRAY nucleic acid mass spectrometry was applied to detect the genotypes of CYP2D6,the gene encoding cytochrome P450 2D6 enzyme,and CHAT,the gene encoding acetylcholine trans-ferase.After 9 months of follow-up,drug efficacy was indirectly determined by neurological func-tion scales,caregiver evaluations,and drug prescribing behaviors,and thus,the 50 patients on donepezil alone were divide into effective group(n=28)and ineffective group(n=22).Seventy-two patients were divided into adverse reaction group(n=12)and no adverse reaction group(n=60).Multivariate logistic regression analysis was used to analyze the correlation between donepezil efficacy and pharmacogenomics.Results The frequencies of CHAT rs3793790 locus carrying G allele and rs2177370 locus carrying A allele were significantly higher in the effective group than the ineffective group(35.71％vs 9.09％,P=0.029;42.86％vs 9.09％,P=0.008).Multivariate lo-gistic regression analysis showed that donepezil was more effective in those who carrying rs3793790 G allele and/or rs2177370 A allele in the CHAT gene than those who carrying neither of the alleles(95％CI:1.20-34.47,P=0.030).There were no statistical differences in the CYP2D6 gene-adjusted activity score and whether or not carrying*10 between the patients with and without adverse reactions(P＞0.0 5).Conclusion In patients with a continuous spectrum of AD,donepezil efficacy is associated with CHAT gene polymorphisms,but there is no correlation between donepezil adverse reactions and CYP2D6 genotype.

Metabolic associated fatty liver disease(MAFLD)has become the most common liver disease in the world,including simple hepatic steatosis,steatohepatitis,liver fibrosis/cirrhosis,and liver cancer,and it is often associated with metabolic syndrome.MAFLD has complex pathological manifestations,and there are still no new drugs on the market in China.In the past,traditional Chinese medicine often treated this disease from the perspective of food,phlegm-dampness,damp-heat,or liver depression and spleen deficiency,but a detailed analysis showed that the pathological process of the disease was consistent with the theory of"six stagnation diseases"in traditional Chinese medicine.This article briefly introduces the origin of the pathogenic theory of"six stagnation diseases",the pathological features of the"six stagnation diseases"leading to fatty liver disease,the key points of syndrome differentiation and treatment,and clinical practice,so as to promote clinical treatment through an in-depth understanding of the traditional Chinese medicine pathogenesis of MAFLD.

Objective To explore the mediating role of eating disorders in the relationship between body image satisfaction and anxiety symptoms among college students,and further examine the moderating effect of mindfulness on this mediating pathway.Methods By using convenience sampling,we conducted baseline and follow-up surveys among freshmen and sophomores at two universities in Xizang Autonomous Region from September to December 2021.Measurements included the Generalized Anxiety Disorder Scale,the body image satisfaction subscale of the Multidimensional Body-Self Relations Questionnaire,the Eating Attitudes Test,and the Mindful Attention Awareness Scale.Data analyses performed using SPSS 23.0 included Pearson correlation analysis,mediation(model 4),and moderation(model 58)effect analysis.Results A total of 2 993 students participated in both the baseline and follow-up surveys,including 1 007 males(34.3％)and 1,666 Tibetan and other ethnic minorities(56.8％),with an average age of 19.8(SD=1.3)years.Body image satisfaction significantly predicted anxiety symptoms,and this relationship was partially mediated by disordered eating.The presence of mindfulness moderated the impact of body image satisfaction on disordered eating and the influence of disordered eating on anxiety symptoms,indicating varying strengths of these relationships at different levels of mindfulness.Conclusion This study demonstrates that body image satisfaction can significantly predict anxiety symptoms,with disordered eating playing a mediating role in this relationship.The moderating effect of mindfulness further reveals that students with high levels of mindfulness are less likely to experience eating disorders influenced by body image dissatisfaction.Interventions for college students'mental health should consider including management of body image and eating behaviors,as well as mindfulness training.

Objective:To investigate the feasibility of conducting active surveillance (AS) for low risk papillary thyroid microcarcinoma (PTMC) in China and to examine the factors in association with disease progression during AS.Methods:This study was a prospective observational research conducted from Jun. 2018 to Aug. 2022 at Ruijin Hospital affiliated to Shanghai Jiao Tong University School of Medicine. Seventy-three patients with cytologically confirmed low-risk PTMC were enrolled in this study. They were followed up by ultrasonography, and the observed nodules were re-assessed whether or not to have disease progression. Disease progression was defined as having nodule enlarged more than 3 mm in any of diameters measured on ultrasound, or/and presence of suspicious lymph node metastasis.Results:The median follow-up time was 33 months. At the time of last follow-up, 16 cases (21.9%) exhibited disease progression, including 9 cases (12.3%) with suspicious lymph nodes detected by ultrasound, and 8 cases (11.0%) with lesion enlargement; one case (1.3%) exhibited both situations. The univariate chi-square analysis revealed that young patients (≤45 years old, P=0.041), presence of microcalcifications ( P=0.032), initial larger nodule (diameter greater than 7 mm, P=0.003), and elevated thyroid autoantibody levels ( P=0.008) were associated with disease progression. Multiple regression analysis showed elevated thyroid autoantibodies ( OR=4.311, P=0.030) and initial larger nodule ( OR=6.196, P=0.034) were independent risk factors for PTMC progression,respectively. Conclusions:AS for low-risk PTMC is a feasible and effective. During the observation, ultrasound can reveal suspicious lymph nodes and nodule enlargement, which are crucial indicators for assessing disease progression. Patients with initially larger nodule size and elevated thyroid autoantibody level are more likely to exhibit disease progression and should receive closer attention.

Cytopharmaceutical based on macrophages is a breakthrough in the field of targeted drug delivery. However, it remains a challenge to localize and control drug release while retaining macrophage activity and exerting its immunotherapeutic effect. Herein, a localized light-triggered release macrophage cytopharmaceutical (USIP@M) was proposed, which could utilize the tumor targeting and immunotherapy effects of macrophages to reverse the immune suppression of tumor microenvironment (TME). Amphiphilic block copolymers with ultraviolet (UV)-responsive o-nitrobenzyl groups were synthesized and co-loaded with sorafenib (SF), IMD-0354 (IMD), and upconverting nanoparticles (UCNPs), which were then taken up by macrophages, and the targeted delivery of drugs was realized by using the tumor tropism of macrophages. UCNPs converted near-infrared light with strong penetrability and high safety into UV light, which promoted the photoresponsive depolymerization of block copolymers and production of exosomes from USIP@M, accelerated drug efflux and maintained the activity of macrophages. IMD simultaneously polarized carrier macrophages and tumor-associated macrophages to exert the antitumor effect of macrophages, enhance T cell immunity, and alleviate the immunosuppressive state of TME. Synergistically with the chemotherapeutic effect of SF, it could effectively kill tumors. In conclusion, based on the localized light-triggered release strategy, this study constructed a novel macrophage cytopharmaceutical that could localize and control drug release while retaining the activity of macrophages and exerting its immunotherapeutic effect, which could effectively treat solid tumors.
