The stimulate effects of synthetical endogenous peptides, tuftsin (Tuf) and thymopentin(TP5), on phagocytic function were studied. After subcutaneous administration (sc) of Tuf, thelysozyme content in both M? and sera, and the acid phosphatase activity in M?, were increasedin a dose-dependent manner. The peak time of serum lysozme level following a sigle sc injectionof Tuf was about on the 6th day. The elevation of lysozyme in sera was delayed and enhancedstrongly by Freund incomplete adjuvant (FIA). In cylcophosphamide (Cy) treated mice,TP5further increased both lysozyme content amd acid phosphatase activity in M?activated byCy, and recovered the lysozyme level in spleen inhibited by cy. The results suggested thatTP5could not only activate the funceion of M?, but recover the number of M?decreased by im-mumoimhibitant.

Objective:
To explore the effect and mechanism of omega 3-polyunsaturated fatty acid(ω3-PUFA) dietary intervention on mitochondrial function of white adipose tissue in adult rats with postnatal early overfeeding.
Methods:
An overfed animal model by adjusting litter size was developed for the study of neonatal overfeeding. The litter size was adjusted to 3 male rats per litter(small litter, SL group) and 10 pups per litter(normal litter, NL group). After weaning(week 3), the pups were fed standard chow or ω3-PUFA diet(SL-FO) until postnatal weeks 13. Food intake, body weight, and rectal temperature of rats were measured regularly, and energy metabolism of animals was monitored in week 13. During week 3 and 13, subcutaneous adipose tissue was collected. Inguinal preadipocytes of mice were isolated and induced to differentiate, and 50 μmol/L eicosapentaenoicacid(EPA) was administered for 48 h at the late stage of differentiation. The mRNA and protein expression levels of mitochondrial related genes, mitochondrial copy number, and oxygen consumption rate of adipocytes were detected in adipose tissue and adipocytes.
Results:
By the 3rd week, the body weight, food intake, and fat cell area in SL group were higher than those in NL group while the body temperature was lower until to 13 weeks. By the 13th week, the O2 consumption, CO2 output, and heat production of rats in SL group were lower than those in NL group. Meanwhile, the expressions of mitochondrial function related genes such as uncoupling protein 1(UCP1), carnitine palmitoyltransferase 1(CPT1), SIRT1, and mitochondrial biosynthesis regulatory gene peroxisome proliferator-activated receptor coativator-1 (PGC1α) in adipose tissue by the 3rd and 13th week were significantly reduced(

OBJECTIVE:
To construct a recombinant lentiviral expression vector pCDH-Daxx-EGFP to investigate the effect of Daxx on the proliferation of vascular smooth muscle cells (VSMCs).
METHODS:
The recombinant lentiviral expression vector pCDHDaxx-EGFP was constructed using PCR-based accurate synthesis method. After identification by sequencing and enzyme digestion, the recombinant lentiviral vector was contransfected into 293T cells with lentivirus packaging vector. The recombinant lentivirus particles were collected and purified to infect VSMCs, whose expression of Daxx was detected with Western boltting. The cells infected with the empty vector pCDH-EGFP or pCDH-Daxx-EGFP were incubated in serum-free medium or in the presence of angiotensin Ⅱ (AngⅡ). The cell viability was determined with MTT assay, and the cell cycle changes were analyzed with flow cytometry. The cell migration ability was assessed using a scratch wound healing assay. The expression of p-Akt protein in the cells was detected using Western blotting.
RESULTS:
Double enzyme digestion and sequencing confirmed successful construction of the recombinant plasmid. Compared with the cells infected with the empty vector, the cells infected with pCDH-Daxx-EGFP exhibited significantly increased expressions of Daxx protein ( < 0.05). AngⅡ treatment of the cells infected with the pCDH-Daxx-EGFP, as compared with the cells infected with the empty vector, significantly lowered the cell viability, S phase cell ratio and cell migration ability ( < 0.05), and significantly decreased the expression level of p-Akt protein ( < 0.05).
CONCLUSIONS
We successfully constructed the recombinant lentiviral vector pCDH-Daxx-EGFP and overexpressed Daxx in primary cultured VSMCs using this vector. Daxx overexpression can inhibit AngⅡ-induced proliferation and migration in VSMCs probably by regulating p-Akt protein.

ObjectiveTo investigate the effect and mechanism of polysaccharide in water extract of Cyclocarya paliurus (CPWP) in inhibiting benign prostatic hyperplasia (BPH). MethodsCPWP was obtained by heating reflux, aqueous extraction, alcohol precipitation, and freeze drying. The chemical composition and structural properties of CPWP were analyzed by high performance liquid chromatography with 1-pheny-3-methyl-5-pyrazolone pre-column derivatization and infrared spectroscopy. Male SD rats were randomly assigned into control, model, finasteride (ig 5 mg·kg-1), and low-, medium-, and high-dose (ig 50, 75, 100 mg·kg-1) CPWP groups, with 8 rats in each group. The BPH model was established by subcutaneously injecting propionate testosterone in castrated rats. The rats in the drug intervention groups were administrated with corresponding drugs, and those in the control group were administrated with an equal volume of normal saline each day. After 30 consecutive days, the rats were sacrificed, and the prostate tissue was separated and weighed. The effects of drug interventions on the body weight, prostate wet weight, and prostate index of rats were examined. The prostate tissue was stained with hematoxylin-eosin (HE) for observation of pathological changes. Enzyme-linked immunosorbent assay was employed to measure the level of dihydrotestosterone (DHT), and immunohistochemical staining was used to detect the expression of steroid 5 alpha-reductase 2 (SRD5A2) and Ki67 in the prostate tissue. ResultsCPWP was identified as a saccharide, with characteristic absorption peaks of saccharides. CPWP showed the total sugar content of 44.15% and molecular weight within the range of 5.5-78.8 kDa, being composed of mannose, rhamnose, galacturonic acid, glucose, galactose, xylose, and arabinose. Compared with the control group, the model group had significantly increased prostate wet weight and prostate index (P<0.01), thick and tall prostate epithelial cells, increased internal wrinkles, papillary expansion into the cavity, an elevation in DHT level in the serum, and up-regulated expression of SRD5A2 and Ki67 in the prostate tissue (P<0.05, P<0.01). Compared with the model group, both the finasteride and CPWP groups showed decreases in prostate wet weight and prostate index (P<0.05, P<0.01), thinned prostate epithelial cells, with only a small portion of internal wrinkles and papillary expansion into the cavity, shortened papillary protrusions, lowered DHT level in the serum, and down-regulated expression of SRD5A2 and Ki67 in the prostate tissue (P<0.01). Moreover, CPWP exerted effects in a dose-dependent manner. ConclusionCPWP inhibits BPH by regulating the expression of SRD5A2.

Inflammation is involved in the development of various acute and chronic diseases in the body. Sustained inflammatory responses are key driving factors for diseases such as cancer, neurodegenerative diseases, cardiovascular diseases, metabolic syndrome, inflammatory bowel disease, and arthritis. Therefore, finding anti-inflammatory drugs is crucial for the prevention and treatment of various diseases. In recent years, there has been increasing attention to finding natural drugs with minimal toxic side effects. Lonicerae Japonicae Flos and Lonicerae Flos, as traditional Chinese medicines potent in clearing heat and removing toxins, have strong biological activity and multiple pharmacological effects. They are widely distributed in the plant world and have significant medicinal value. With the continuous advancement of the research on Lonicerae Japonicae Flos and Lonicerae Flos, they have been widely used in the medical field and possess great development potential. Currently, research mainly focuses on the anti-inflammatory mechanisms of Lonicerae Japonicae Flos and Lonicerae Flos, while systematic summaries of their anti-inflammatory active ingredients are rare. Therefore, this paper focuses on the differential analysis of the anti-inflammatory active components of Lonicerae Japonicae Flos and Lonicerae Flos. In addition, it reviewed the possible mechanisms by which extracts and active ingredients of Lonicerae Japonicae Flos and Lonicerae Flos may exert anti-inflammatory effects through various pathways, such as influencing the release of cellular inflammatory factors, regulating inflammatory signaling pathways such as nuclear factor-κB (NF-κB), mitogen-activated protein kinase (MAPK), signal transducer and activator of transcription 3 (STAT3), MAPK/extracellular signal-regulated kinase (ERK)/c-Jun N-terminal kinase (JNK), phosphatidylinositol 3-kinase (PI3K)/protein kinase B (Akt)/NF-κB, and Janus kinase (JAK)/signal transducer and activator of transcription (STAT) signaling pathways, increasing antioxidant stress capacity, enhancing immune defense capabilities, and improving intestinal microbiota, aiming to provide a theoretical basis for the rational clinical application of Lonicerae Japonicae Flos and Lonicerae Flos.
