ObjectiveTo establish a subcutaneous xenograft model of gastric cancer in nude mice and to identify differentially expressed genes （DEGs） affected by Jianpi Yangzheng Xiaozheng formula （JPYZXZ） in diffuse gastric cancer （DGC） using transcriptome sequencing. The study aims to identify potential key prognostic factors and preliminarily elucidate the therapeutic mechanism of JPYZXZ. MethodsSubcutaneous tumor tissues were collected from nude mice treated with JPYZXZ （6 g·kg^-1）and from the untreated traditional Chinese medicine control group. High-throughput RNA sequencing was performed to extract and analyze total RNA and identify DEGs， followed by functional enrichment analysis. DEGs were intersected with cancer-associated fibroblast （CAF）-related genes identified from single-cell RNA sequencing （scRNA-seq） data. A Cox proportional hazards regression model （Cox model） was constructed to identify potential key targets， among which DAZ interacting protein 1 （DZIP1） was selected. The role of DZIP1 in DGC progression was further verified through in vitro and in vivo experiments. ResultsTranscriptome sequencing revealed that DEGs regulated by JPYZXZ were significantly enriched in biological processes such as focal adhesion， phosphatidylinositol 3-kinase/protein kinase B （PI3K/Akt） signaling pathway， and vascular development （P<0.05）. Intersection analysis with CAF marker genes identified ten potential common target genes. Cox regression analysis combined with the Cancer Genome Atlas （TCGA） dataset for stomach adenocarcinoma （STAD） confirmed that DZIP1 is an independent prognostic factor significantly associated with poor outcomes. Transcriptome and immunohistochemical analyses showed that DZIP1 expression was significantly higher in gastric cancer tissues than in adjacent tissues， while JPYZXZ treatment downregulated DZIP1 expression in a dose-dependent manner. Clinical data further demonstrated that serum DZIP1 levels in patients treated with JPYZXZ were significantly lower than those in the control group. ConclusionJPYZXZ may inhibit the malignant progression of DGC by downregulating DZIP1 expression， thereby suppressing CAF activation and epithelial-mesenchymal transition （EMT）. These findings provide experimental evidence and identify DZIP1 as a potential therapeutic target in DGC treatment.

Objective:To explore the rehabilitation effect of multi-factor intervention based on the Finnish model of prevention of cognitive impairment in the elderly on patients with cognitive impairment after first-episode stroke, and to provide reference for rehabilitation nursing of cognitive impairment after stroke.Methods:The quasi-experiment research scheme was adopted and convenience sampling method was used to select participants with first-episode stroke cognitive impairment hospitalized in the General Hospital of Tianjin Medical University Airport Site. The 50 patients admitted from January to June 2022 were selected as the control group, and 50 patients admitted from July to December 2022 were selected as the intervention group. The control group received routine rehabilitation nursing and health education, and the intervention group received the Finnish model of prevention of cognitive impairment in the elderly on patients before discharge on the basis of the control group. The Mini-Mental State Examination (MMSE) and Health Education Compliance Assessment Scale for Stroke Patients were used to evaluate the changes of overall cognitive function and rehabilitation compliance before intervention, 3 and 6 months after intervention.Results:The final control group included 49 cases, including 35 males and 14 females, aged (64.67 ± 7.47) years old; the intervention group included 50 cases, 32 males and 18 females, aged (66.68 ± 8.75) years old. Before intervention, there were no significant differences in overall cognitive function and compliance of rehabilitation score ( P>0.05). At 3 and 6 months after intervention, the overall cognitive function score, the total score on compliance of rehabilitation, dimension scores of diet compliance, exercise rehabilitation compliance and health behavior compliance of the intervention group were (26.36±2.36) , (125.96 ± 13.80) , (23.30 ± 5.26) , (27.72 ± 4.46) , (43.66 ± 6.80) and (27.26 ± 3.71) , (152.44 ± 9.06) , (30.12 ± 6.42) , (33.32 ± 3.02) , (52.36 ± 4.70) , respectively. They were higher than the control group (24.04 ± 4.50) , (116.67 ± 10.26) , (19.31 ± 3.95) , (25.29 ± 3.45) , (40.59 ± 4.33) and (24.27 ± 4.33) , (138.92 ± 16.71) , (24.20 ± 4.48) , (30.00 ± 5.53) , (47.65 ± 8.03) , and the differences had statistical significance ( t values were -5.31- -2.67, all P<0.05). According to the variance analysis of repeated measurement, intergroup and time factor, the interaction between groups and time had significant impact on general cognitive function score, the total score of rehabilitation compliance, the dimension scores of diet, exercise rehabilitation and health behavior compliance ( Fgroup values were 8.33-18.08, Ftime values were 135.71-944.69, Finteraction values were 5.46-27.30, all P<0.05) . Time factor had significant impact on patient medication adherence score ( Ftime=206.23, P<0.05) . Conclusions:Multi-factor intervention based on the Finnish model of prevention of cognitive impairment in the elderly can improve the overall cognitive function and rehabilitation compliance of patients with cognitive impairment after first-episode stroke.

AIM:To investigate the effects of cannabinoid receptor agonist WIN55212-2(WIN)on acute lung injury(ALI)in septic mice,and to explore its potential mechanisms through glycolysis.METHODS:A mouse model of septic ALI was established by intraperitoneal injections of lipopolysaccharide(LPS).Male C57BL/6J mice were randomly divided into 4 groups(n=6):(1)control group;(2)LPS group,receiving intraperitoneal injections of LPS at 10 mg/kg;(3)LPS+WIN group,receiving 1 mg/kg WIN intraperitoneally 30 min prior to LPS injection;(4)LPS+WIN+MHY1485[mammalian target of rapamycin(mTOR)activator]group,receiving 10 mg/kg MHY1485 intraperitoneally 1 d before LPS injection and 1 mg/kg WIN plus 10 mg/kg MHY1485 30 min before LPS injection.Tissues were collected 24 h after modeling for analysis.Lung indexes were calculated,and histopathological changes of lung tissues were observed via he-matoxylin-eosin(HE)staining.Inflammatory cytokines interleukin-1β(IL-1β)and IL-10 in lung tissues,and lactic acid and lactate dehydrogenase A(LDHA)in serum were quantified using ELISA.The levels of mTOR/hypoxia-inducible fac-tor-1α(HIF-1α)/6-phosphofructo-2-kinase/fructose-2,6-biphosphatase 3(PFKFB3)signaling pathway-related proteins were assessed by Western blot.RESULTS:Compared with control group,the LPS group exhibited an increased lung in-dex,significant lung tissue damage,an increase in IL-1β levels(P＜0.05),a decrease in IL-10 levels(P＜0.05),and el-evated expressions of lactate and LDHA(P＜0.05),along with increased levels of phosphorylated mTOR(p-mTOR),HIF-1α and PFKFB3 proteins(P＜0.05).The LPS+WIN group showed improvements with a reduced lung index(P＜0.05),lessened lung injury,decreased IL-1β levels(P＜0.05),increased IL-10 levels(P＜0.05),and lower levels of lactic acid,LDHA,p-mTOR,HIF-1α,and PFKFB3(P＜0.05).Conversely,the LPS+WIN+MHY1485 group displayed increased lung indexes and lung tissue damage,elevated IL-1β levels(P＜0.05),reduced IL-10 levels(P＜0.05),and higher expressions of lactic acid,LDHA,p-mTOR,HIF-1α and PFKFB3(P＜0.05)compared to the LPS+WIN group.CONCLUSION:WIN55212-2 mitigates sepsis-induced ALI,potentially by modulating the mTOR/HIF-1α/PFKFB3 sig-naling pathway,thereby inhibiting glycolysis and alleviating inflammatory responses.

As one of the pathogenic mechanisms contained in The Inner Canon of Yellow Emperor （《黄帝内经》）， “disease with latent pathogen induced by a new pathogen” means that the induced new pathogen resulted to a combination of the latent previous pathogen and the new pathogen， which caused the disease. Based on this， it is believed that the change of “nodule-cancer transformation” of pulmonary nodules is actually based on the deficiency of original qi， and the new pathogen induces the latent pathogens like phlegm coagulation， qi stagnation， blood stasis， toxicity， so healthy qi can not drive the pathogens out， and the long-time detention generated into cancerous turbidity， and deve-loped into cancerous tumour at the end. Therefore， based on the three-stage treatment of unformed cancer， dense cancerous toxin， and developed cancer， the clinical practice applied six methods of clearing， expelling， dissipating， tonifying， harmonizing， and transforming， taking into account both the manifestation and root cause， moving the treatment window of pulmonary nodules forward， attacking the pathogens when the toxin was not yet overbearing， supporting the healthy qi before declining， delaying the process of nodules-cancer transformation， and providing ideas for the prevention and treatment of pulmonary nodules “nodule-cancer transformation” in traditional Chinese medicine.

Objective To investigate the effects of cannabinoid receptor agonist,WIN55212-2(WIN),on acute kidney injury(AKI)in mice with sepsis and its underlying mechanism.Methods Twenty-four healthy male mice were divided into(n=6):Control group,sepsis group(LPS group),sepsis+WIN55212-2 group(LPS+WIN group)and sepsis+WIN55212-2+mTOR activator MHY1485 group(LPS+WIN+MHY group).The sepsis model was constructed by intraperitoneal injection of LPS.After the tissue and blood samples were harvested in 24 h after modeling,ELISA was used to determine the contents of IL-1β,IL-18 and lactate dehydrogenase A(LDHA)in the renal tissues,as well as Scr,kidney injury molecule-1(KIM-1)and lactic acid(LA)in the serum.HE staining was employed to observe the pathological changes of kidney tissue and Paller score was calculated.The expression of p-AKT,p-Mtor and 6-phosphofructokinase-2/fructose-2,6-biphosphatase 3(PFKFB3)in the renal tissues was detected by Western blotting.Results Compared with the Control group,the LPS group had obvious kidney tissue damage,increased Paller score(P＜0.05),increased serum contents of lactic acid,Scr and KIM-1(P＜0.05),up-regulated contents of LDHA,IL-1β and IL-18 in the renal tissues(P＜0.05),and elevated expression levels of p-AKT,p-Mtor and PFKFB3 in the renal tissues(P＜0.05).Milder pathological injury in kidney tissue,decreased Paller score(P＜0.05),reduced contents of lactic acid,Scr and KIM-1(P＜0.05),decreased contents of LDHA,IL-1β and IL-18(P＜0.05),and lower expression of p-AKT,p-Mtor and PFKFB3 were observed in the LPS+WIN group than the LPS group(P＜0.05).The LPS+WIN+MHY group had notably higher Paller score(P＜0.05),raised contents of lactic acid,Scr and KIM-1(P＜0.05),increased contents of LDHA,IL-1β and IL-18(P＜0.05),and up-regulated expression of p-AKT,p-Mtor and PFKFB3(P＜0.05)when compared with the LPS+WIN group.Conclusion WIN can alleviate AKI in sepsis,and it may reduce the level of glycolysis in renal tissue,and alleviate inflammation through inhibiting AKT/Mtor/PFKFB3 signaling pathway.

Objective:To investigate the quantification assessment of segmental volume after thigh liposuction utilizing three-dimensional(3D) scanning technology.Methods:This retrospective study was performed with the analysis of 3D scanning images of patients who had undergone bilateral thigh liposuction in Body Contouring & Fat Grafting Center, Plastic Surgery Hospital, Chinese Academy of Medical Sciences from January 2018 to September 2022. Preoperative and postoperative 3D scanning were performed to build visual 3D models of bilateral thighs. From top to the bottom, bilateral thighs were segmented into seven sections with a space of 5 cm in acquired 3D model. Certain measurements and calculation of preoperative and postoperative volume and volume change rate of the overall thigh and each segment were conducted, to validate the efficiency of liposuction (EOL). Additionally, EOL of each thigh segment was computed and the symmetry of bilateral thighs was analyzed before and after surgery. The volume differences were computed using the paired Wilcoxon rank-sum test, and intraclass correlation coefficient (ICC) was exerted to assess the symmetry of bilateral thighs before and after surgery.Results:A total of 36 female patients were included in the study, with an age range of 18 to 49 years and a mean age of (28.6±7.6) years. Follow-up duration ranged from 23 to 1 133 days postoperatively, with a mean follow-up period of 274.7 days. The results of 3D scanning measurements indicated significant changes ( P<0.01) in both the overall volume of the thigh and the volumes of each segment before and after surgery. The highest volume change rate and EOL were observed in the uppermost segment, and the volumetric change rate and EOL exhibited a descending trend across the segments of the thigh from the uppermost to the lowermost segments. The ICC of the volume of each segment consistently surpassed 0.950 whether preoperatively or postoperatively, indicating a high level of symmetry between the bilateral thighs, and the ICC of overall volume showed a notable increase from 0.992 preoperatively to 0.997 postoperatively. Conclusion:3D scanning technology can be exerted to quantify the volume changes before and after thigh liposuction. This study provided quantitative and objective evidence to confirm the efficacy of thigh liposuction procedure, elucidating that the most significant liposuction effects observed in the uppermost segment of the thigh. Moreover, postoperative assessments reveal a further enhancement in bilateral thigh symmetry.

Obesity and related metabolic syndromes have been recognized as important disease risks,in which the role of adipokines cannot be ignored.Adiponectin(ADP)is one of the key adipokines with various beneficial effects,including improving glucose and lipid metabolism,enhancing insulin sensitivity,reducing oxidative stress and inflammation,promoting ceramides degradation,and stimulating adipose tissue vascularity.Based on those,it can serve as a positive regulator in many metabolic syndromes,such as type 2 diabetes(T2D),cardiovascular diseases,non-alcoholic fatty liver disease(NAFLD),sarcopenia,neurodegenerative diseases,and certain cancers.Therefore,a promising therapeutic approach for treating various metabolic diseases may involve elevating ADP levels or activating ADP receptors.The modulation of ADP genes,multimerization,and secretion covers the main processes of ADP generation,providing a comprehensive orientation for the development of more appropriate therapeutic strategies.In order to have a deeper understanding of ADP,this paper will provide an all-encompassing review of ADP.
