The traditional theory of "the spleen governs the dispersion of essence" refers to the spleen's pivotal role in distributing refined nutrients throughout the body. In traditional Chinese medicine （TCM）， lipids are categorized under "gaozhi （膏脂）"， and their transportation and metabolism via apolipoproteins are believed to be closely related to the spleen's dispersing function. The liver， which synthesizes apolipoproteins， is functionally linked to the spleen system in TCM. Impaired dispersion of essence by the spleen and disrupted transportation of gaozhi constitute the pathological mechanism of dyslipidemia due to spleen deficiency. Strengthening the spleen and resolving dampness is the core therapeutic principle. From the perspective of modern medicine， this may involve promoting hepatic functional recovery related to lipid metabolism， thereby enhancing lipid processing and reducing the levels of abnormally accumulated lipids in the bloodstream.

OBJECTIVES: To investigate the role of PTEN-induced putative kinase 1 (PINK1) in regulating the viability, migration, and apoptosis of colorectal cancer (CRC) cells, and to explore its potential epigenetic mechanisms. METHODS: PINK1 was overex-pressed or knocked down in HCT116 and DLD1 CRC cell lines using lentiviral vectors, with efficiency verified by qRT-PCR and Western blotting. Cell proliferation, colony formation, migration, and apoptosis were assessed using CCK-8, colony formation, wound healing, Transwell, and Hoechst 33258 staining assays, respectively. Protein levels of apoptosis-related and histone modification-related markers were analyzed by Western blotting. Genome-wide chromatin accessibility was profiled using ATAC-seq. RESULTS: PINK1 expression was significantly downregulated at both mRNA and protein levels in CRC tissues compared to normal tissues. PINK1 overexpression inhibited cell prolifera-tion, colony formation, and migration in HCT116 and DLD1 cells (all P<0.05), whereas PINK1 knockdown promoted these malignant phenotypes (all P<0.05). PINK1 overex-pression induced apoptosis, associated with decreased levels of anti-apoptotic proteins (Mcl-1, Bcl-2, Bcl-xl) and increased pro-apoptotic Bax (all P<0.05), without altering p53 expression. Mechanistically, PINK1 overexpression reduced the expression of histone H3 lysine 9 trimethylation (H3K9me3) and histone H3 lysine 27 trimethylation (H3K27me3), and increased the expression of histone H3 lysine 9 acetylation (H3K9ac) and histone H3 lysine 27 acetylation (H3K27ac). It also downregulated key histone-modifying enzymes, including EZH2, EZH1, SUZ12, and histone deacetylase 3 (HDAC3) (all P<0.01). ATAC-seq revealed that PINK1 overexpression increased chromatin accessibility, particularly around transcription start sites. CONCLUSIONS PINK1 acts as a tumor suppressor in colorectal cancer by inhibiting proliferation and migration, promoting apoptosis, and remodeling the epigenetic landscape through altering histone modifications and enhancing chromatin accessibility.

Insufficient alveolar bone thickness increases the risk of periodontal dehiscence and fenestration, especially in orthodontic tooth movement. Abaloparatide (ABL), a synthetic analog of human PTHrP (1-34) and a clinical medication for treating osteoporosis, has recently demonstrated its potential in enhancing craniofacial bone formation. Herein, we show that intraoral submucosal injection of ABL, when combined with mechanical force, promotes in situ alveolar bone thickening. The newly formed bone is primarily located outside the original compact bone, implying its origin from the periosteum. RNA sequencing of the alveolar bone tissue revealed that the focal adhesion (FA) pathway potentially mediates this bioprocess. Local injection of ABL alone enhances cell proliferation, collagen synthesis, and phosphorylation of focal adhesion kinase (FAK) in the alveolar periosteum; when ABL is combined with mechanical force, the FAK expression is upregulated, in line with the accomplishment of the ossification. In vitro, ABL enhances proliferation, migration, and FAK phosphorylation in periosteal stem cells. Furthermore, the pro-osteogenic effects of ABL on alveolar bone are entirely blocked when FAK activity is inhibited by a specific inhibitor. In summary, abaloparatide combined with mechanical force promotes alveolar bone formation via FAK-mediated periosteal osteogenesis. Thus, we have introduced a promising therapeutic approach for drug-induced in situ alveolar bone augmentation, which may prevent or repair the detrimental periodontal dehiscence, holding significant potential in dentistry.

In order to investigate the effects of Fuzi Lizhong Oral liquid on immune function and in-testinal health of chicks,185 1-day-old healthy chicks were randomly divided into 4 groups.The blank control group(CG group)was given normal tap water;the high,medium and low dose groups(FZH group,FZM group and FZL group)were given tap water containing 5.00,2.50 and 1.25 g/L of Fuzi Lizhong Oral liquid,respectively.Starting from the first day of age,the drug was administered continuously for 5 d,and the blood was collected from the subwing vein on the sixth day of the test.The results showed that compared with CG group,thymus index in FZH group was significantly increased(P＜0.05).Compared with CG group,serum IgM,IgG and sIgA in FZH group were significantly increased(P＜0.05),and serum IgG and sIgA in FZM group were signifi-cantly increased(P＜0.05).Compared with CG group,the relative expression of Occludin and Claudin-1 mRNA in FZH group was significantly increased(P＜0.05),and the relative expression of ZO-1 mRNA in FZM and FZH groups was significantly increased(P＜0.05).Compared with CG group,Shannon index of FZH group was significantly increased(P＜0.05),Simpson index of FZH group was significantly decreased(P＜0.05),and many beneficial bacteria such as Strepto-coccus spinosus,Eubacillus spinosus and Lactobacillus spinosus played a synergistic role.The results showed that adding 5.00 g/L Fuzi Lizhong Oral liquid in drinking water could improve the immunity of chicks,maintain the intestinal barrier function of chicks,increase the intestinal flora richness and promote the intestinal health of chicks.

Objective:To construct and validate a predictive model for postoperative recurrence in early non-small cell lung cancer patients.Methods:The clinical data of 252 patients with early non-small cell lung cancer admitted to the 926th Hospital of Joint Logistic Support Force of PLA from January 2016 to January 2018were retrospectively collected. All of the patients underwent surgical treatment and they were followed up for 5 years after surgery, according the recurrence after surgery, they were divided into the recurrence group (103 cases) and non- recurrence group (149 cases). The risk factors for postoperative recurrence in early non-small cell lung cancer patients were analyzed. A predictive model for postoperative recurrence in early non-small cell lung cancer patients was constructed and validated.Results:The results of Logistic regression analysis showed that tumor long diameter≥ 3 cm, lymph node metastasis, low differentiation, spicules and pleural traction were independent risk factors for postoperative recurrence in early non-small cell lung cancer patients ( P<0.05). Using R4.0.3 statistical software, the dataset was randomly divided into a training set and a validation set, with a sample size of 176 cases in the training set and 76 cases in the validation set. A prediction model was constructed, with thearea under the curve (AUC) of the receiver operating characteristic (ROC) curve of 0.754 (95% CI 0.679 - 0.828) in the training set and AUC of 0.749 (95% CI 0.634 - 0.864) in the validation set. The model was subjected to a Hosmer-Lemeshow Goodness-of-Fit Test in the validation set, χ2 = 11.31, P = 0.185. Conclusions:The predictive model base on tumor long diameter ≥ 3 cm, lymph node metastasis, low differentiation, spicules and pleural traction can identify patients at high risk of postoperative recurrence in early non-small cell lung cancer effectively.

A total of 300 1-day-old broilers were randomly divided into 5 groups with 5 replicates per group and 12 broilers per replicate.The control group was given free drinking water(CG),the astragalus polysaccharide control group(HPS)received 0.8 mL/L of astragalus polysaccharide o-ral liquid in drinking water,and the experimental groups(SBL,SBM,SBH)received 1.5,3.0,4.5 mL/,of Shenling Baizhu Oral Liquid in drinking water.The results showed as follows:com-pared to the CG group,SIgA content in HPS group,group SBM and group SBH was significantly increased(P＜0.05),IL-6 and IL-1β contents were significantly decreased(P＜0.05),Occludin,Mucin-2 and Bcl-2 contents were significantly increased(P＜0.05).The results of 16S rRNA test showed that the specific OUT number in groups HPS and SBM was significantly higher than that in group CG(P＜0.05),α diversity analysis showed that compared with group CG,Chao1 index and Simpson index of group HPS,group SBM and group SBH were significantly increased,and βdiversity analysis showed that there were significant differences in species composition between test group and blank control group(P＜0.05).The relative abundance analysis at the phylum level showed that the relative abundance of Firmicutes and Bacteroides in groups SBM and SBH was significantly higher than that in group CG(P＜0.05).The above results showed that Shenling Baizhu Oral Liquid could improve the intestinal health and enhance the resistance of broilers.

Objective:To investigate the effects of psychological state on the setup errors of radiotherapy for breast cancer patients.Methods:A prospective cohort study was conducted. A total of 193 breast cancer patients in Cancer Hospital, Chinese Academy of Medical Sciences and Peking Union Medical College from October 2022 to May 2023 were selected. Radiotherapy was performed after fixation with an integrated multi-functional device for the head, chest and abdomen. Psychological status of patients was assessed by using 9-item health questionnaire (PHQ-9) and generalized anxiety disorder 7 self-rating scale (GAD-7) before first radiotherapy, the 10th radiotherapy and the last radiotherapy. Based on the results of the questionnaires, patients were divided into psychological problem (anxiety or depression) group and non-psychological problem group. The general data and setup errors of radiotherapy in both groups were compared.Results:All the 193 patients were female, with a median age of 47 years. There were 53 patients in psychological problem group and they underwent a total of 507 image-guided procedures, with setup errors [ M ( Q1, Q3)] of 0.18 (0.07, 0.33), 0.20 (0.10, 0.33) and 0.19 (0.09, 0.30) in the left-right (X), superior-inferior (Y), and anterior-posterior (Z) directions, respectively; the remaining 140 patients in non-psychological problem group underwent 1 240 image-guided procedures, with setup errors [ M ( Q1, Q3)]of 0.17 (0.08, 0.30), 0.20 (0.10, 0.30) and 0.18 (0.09, 0.28) in the X, Y, and Z directions, respectively, and the differences were statistically significant ( Z values were -3.78, -2.00; P < 0.001, P = 0.046). Conclusions:Anxiety and depression have an influence on the setup errors of radiotherapy in patients with breast cancer. In the processs of radiotherapy for breast cancer, it is important to pay attention to the psychological status of patients.

Objective To explore the correlation between the expression level of serum fibrinogen-like protein 1(FGL1)and the indexes of metabolism and renal function in patients with diabetic nephropathy(DN)and diabetes mellitus(DM),and provide reference for clinical diagnosis and treatment.Methods From January 2017 to April 2023,30 patients with DM and treated in Jiangsu Province Hospital of Chinese Medicine were selected as the DM group,68 patients with DN were selected as the DN group,and 36 healthy subjects were selected as the control group.The DN group was further divided into the early DN(DN-E)group(n=38)and the late DN(DN-A)group(n=30)according to whether there was a large amount of proteinuria and the severity.Clinical data such as serum albumin(ALB),estimated glomerular filtration rate(eGFR)and albumin-to-creatinine ratio(ACR)were collected.Serum FGL1 level was detected by enzyme-linked immunosorbent assay(ELISA).Pearson linear correlation was used for correlation,the diagnostic value was analyzed by ROC curve.Results Compared with the control group,the levels of ACR,FGL1 in patients with DM group increased,the levels of eGFR decreased,and the differences were statistically significant(t=5.686,4.336,-4.683,all P<0.05).Compated with the DM group,the levels of ACR,FGL1 in patients with DN-E group was increased,and the level of eGFR was decreased,and the differences were statistically significant(t=5.275,3.454,-4.969,all P<0.05).Compared with the DN-E group,the levels of ACR,FGL1 in the DN-A group were increased,the levels of eGFR were decreased,and the differences were statistically significant(t=7.881,7.051,-5.596,all P<0.05).Serum FGL1 level was negatively correlated with ALB and eGFR(r=-0.638,-0.547,all P<0.05),and positively correlated with ACR(r=0.691,P<0.05).The AUC(95%CI),specificity and sensitivity of serum FGL1 level in the diagnosis of DN were 0.947(0.908～0.987),100%and 82.4%,respectively.Conclusion The level of serum FGL1 in DN and DM patients is high,and the level of serum FGL1 is closely related to the common metabolic indexes such as ALB,eGFR and ACR in the diagnosis of DN,which may have certain clinical diagnostic value.
