Objective:To study the effects of intervention of Jiawei Tongmai Huazhi Decoction in the Wnt/β-catenin pathway on apoptosis of lesion cells in mice with adenomyosis (AM); To discuss its mechanism of action.Methods:The AM mouse model was established using tamoxifen. The mice were divided into model group, Jiawei Tongmai Huazhi Decoction group, and progesterone group according to random number table method, with 7 mice in each group. Additionally, a blank group of 7 female mice was set up. Jiawei Tongmai Huazhi Decoction group received oral administration of Jiawei Tongmai Huazhi Decoction at a dosage of 36.51 g/kg/day, once daily. The progesterone group received oral administration of progesterone at a dose of 0.32 mg/kg twice a week. The blank group and model group received oral administration of the same volume of physiological saline once daily. After 2 months of intervention, the morphology of uterine tissues was observed by HE staining. The levels of carbohydrate antigen 125 (CA125) and prolactin (PRL) in the serum were measured by ELISA. The mRNA levels of Wnt3a and β-catenin in uterine tissues were determined by PCR. The protein expressions of Wnt3a, β-catenin, Bax, and Bcl-2 in uterine tissues were detected by Western blot.Results:Compared with the model group, the levels of serum CA125 and PRL were reduced in the Jiawei Tongmai Huazhi Decoction group ( P<0.05). The protein expressions of Wnt3a, β-catenin, and Bcl-2 were also reduced ( P<0.05), the protein expressions of Wnt3a, β-catenin, and Bcl-2 decreased ( P<0.05), while the protein expressions of Bax increased ( P<0.05). Conclusion:Jiawei Tongmai Huazhi Decoction alleviates the progression of lesions by reducing serum CA125 and PRL levels in AM model mice, and can down-regulate Bcl-2 expression and up-regulate Bax expression, promoting apoptosis of ectopic lesion cells in mice. Its mechanism of action may be related to the inhibition of Wnt/β-catenin pathway related expression proteins.

Objective To investigate the effect of artesunate(ART)on neuroinflammation in depressed mice by regulating the cyclic guanosine monophosphate-adenosine monophosphate synthase(cGAS)-stimulator of interferon gene(STING)pathway.Methods Mice were divided into model group,control group,low-dose ART group,high-dose ART group,fluoxetine group,and high-dose ART+RocA(cGAS-STING pathway activator)group.Sugar solution consumption experiment and forced swimming experiment were applied to evaluate the depressive behavior of mice;HE staining microscopy was applied to detect pathological changes in hippocampal tissue;ELISA method was applied to detect the level of interleukin-6(IL-6),tumor necrosis factor-α(TNF-α),serotonin(5-HT)and dopa-mine(DA);TUNEL staining microscopy was applied to detect neuronal apoptosis;Western blot was applied to detect Bcl-2 associated X protein(Bax),p53,cGAS,and STING proteins.Results Compared to the control group,the mice in the model group exhibited neuronal pustule degeneration,the sugar water consumption rate,level of 5-HT and DA decreased,the rest time of forced swimming increased.The level of IL-6 and TNF-α,neuronal apoptosis rate,expression of Bax,p53,cGAS,and STING proteins all elevated(P＜0.05);Compared with model group,the damage to hippocampus neurons in the ART low-dose group,ART high-dose group and fluoxetine group neuronal pus-tular degeneration was alleviated,while sugar water consumption rate,5-HT,and DA levels increased,the rest time of forced swimming reduced,the level of IL-6 and TNF-α,neuronal apoptosis rate and the expression of Bax,p53,cGAS,and STING proteins reduced(P＜0.05);RocA reversed the improvement effect of high-dose ART on depression in mice.Conclusions ART inhibits neuroinflammation and neuronal apoptosis in depressed mice,and up-regulates amine neurotransmitters expression.The mechanism is potentially related to the blocking of cGAS-STING pathway.

Objective:The aim of this study is to establish the reference interval of refined immune cell subsets by multi-parameter flow cytometry.Methods:In this cross sectional study, a total of 326 healthy participants were included and divided into two groups based on age: 18-40 years old group and 41-60 years old group. Peripheral venous blood was collected in a fasting status. Flow cytometry tests were performed according to previous consensus article. The analysis of reference interval was conducted according to the documents of Clinical and Laboratory Standards Institute (CLSI) EP28-A3c and Health Industry Standards of the People′s Republic of China WS/T 402-2024.Results:The T,B,NK,DC and monocyte refined immune cell subsets applicable to the reference range of the general population mainly include: CD3 +(56.4%-83.3%),CD4 +TEMRRA (0.2%-11.6%), CD4 +TEM (14.9%-52.8%), CD4 +CD28 +(76.3%-99.9%), CD19 +CD5 +(9.7%-45.8%), CD19 +CD27 -(45.7%-90.0%), CD19 +CD27 +(9.8%-54.0%), CD3 +CD16 +CD56 +(1.3%-20.2%), CD3 -CD19 -CD20 -CD14 -CD56 -HLA-DR +(0.4%-2.0%), Monocyte Mo1 subset CD14 +CD16 -(46.3%-94.6%), monocyte Mo2 subset CD14 +CD16 +(2.8%-49.7%), etc. When the Z-value between different age groups was higher than Z* (3.50 cut-off value), the reference intervals of these subsets should be established independently according to age. Conclusions:In this study, the reference intervals of refined subsets of immune cells by multi-parameter flow cytometry has been preliminarily established. For those subgroups that meet the grouping criteria, age should be fully considered in clinical applications and laboratory validation.

OBJECTIVE To explore the clinical effect of tonsil temperature-controlled bipolar radiofrequency ablation technology in the treatment of snoring and mild-moderate-obstructive sleep apnea hyponea syndrome(OSAHS). METHODS Forty-six patients were selected,of which 17 were snoring and 29 were mild-moderate-obstructive sleep apnea-hyponea syndrome cases. Tonsil temperature-controlled bipolar radiofrequency with varying probes was used for all patients. RESULTS A follow-up of 6～18 months was carried out. 9 of 17 snoring cases resulted in recovery. The procedure was effective in 6 cases and not effective in 2 cases. 15 of 29 OSAHS cases resulted in recovery. The procedure was effective in 10 cases and not effective in 4 cases. Overall successful rate was 86.9 %(40/46). The size of tonsils, apnea hyponea index(AHI),snoring scale and Epworth sleepiness score(ESS)were significantly decrease dafter operation(P
