Objective:To investigate the effects and the possible mechanisms of Neiguan(PC6)and Gongsun(SP4)on the hypothalamic-pituitary-adrenal(HPA)axis in rats with functional dyspepsia(FD),thus to provide a theoretical basis for the clinical application of the Eight Confluent Points.Methods:Forty specific-pathogen-free Sprague-Dawley rats were divided into a blank group,a model group,an electroacupuncture(EA)group,and a Western medicine group by the random number table method,with 10 rats in each group.Rats in the blank group did not receive modeling or intervention.Rats in the other three groups were subjected to the FD with mood disorder model using the compound etiology modeling method.After the successful modeling,rats in the model group did not receive any interventions,rats in the Western medicine group received deanxit and mosaprid intervention,and those in the EA group received EA intervention on the ipsilateral Neiguan(PC6)and Gongsun(SP4)for 21 d.The sugar-water consumption rate was measured before the experiment and before and after interventions to assess the emotional status.The gastric emptying rate was measured after interventions to assess the gastrointestinal dynamics.The expression levels of hypothalamic corticotropin-releasing hormone(CRH),pituitary adrenocorticotropic hormone(ACTH),and adrenal corticosterone(CORT)were measured by enzyme-linked immunosorbent assay.Results:Compared with the blank group,the sugar-water consumption rate and the gastric emptying rate were decreased(P<0.01),and the hypothalamic CRH,pituitary ACTH,and adrenal CORT expression levels were increased(P<0.01)in the model group.Compared with the model group,the sugar-water consumption rate and the gastric emptying rate were significantly increased(P<0.01),while the expression levels of hypothalamic CRH,pituitary ACTH,and adrenal CORT were significantly decreased(P<0.01)in the EA group and the Western medicine group.The differences between the EA group and the Western medicine group were not statistically significant(P>0.05).Conclusion:The Eight Confluent Points Neiguan(PC6)and Gongsun(SP4)can improve the mood and gastrointestinal dynamics in FD rats,which may be achieved by down-regulating the hypothalamic CRH,pituitary ACTH,and adrenal CORT,as well as by correcting the HPA axis hyperfunction.

【Objective】 To explore the diagnostic value of platelet long non-coding RNA (lncRNA) as a biomarker for early screening of lung adenocarcinoma (LUAD). 【Methods】 The GSE183635 and GSE89843 datasets, which contained the platelet transcriptome of LUAD and healthy controls, were used for differential analysis, and the intersection of the differentially expressed lncRNA(DElncRNA) of the two datasets was taken. The expression levels of DElncRNA in LUAD tissues and normal control tissues were analyzed using GEPIA2. The expression levels of LINC01088 in platelets of 51 healthy controls and 54 LUAD patients were detected by quantitative Real-time PCR (qRT-PCR), and the diagnostic ability of each index was evaluated by ROC curve. 【Results】 8 DElncRNAs and 1 265 DElncRNAs were obtained from GSE183635 and GSE89843 datasets, respectively. The key DElncRNA LINC01088 was selected after intersection. GEPIA2 analysis showed that the expression level of LINC01088 in LUAD tissues was lower than that in normal lung tissues (P<0.05). Platelet LINC01088 was significantly downregulated in patients with LUAD and early-stage LUAD than in healthy controls(P<0.001). The area under the curve (AUC) of platelet LINC01088 in the diagnosis of LUAD was 0.755, the sensitivity was 81.1%, and the specificity was 67.9%. The AUC for early LUAD diagnosis was 0.727, the sensitivity was 80.0%, and the specificity was 67.9%. The AUC of the combined diagnostic model composed of platelet LINC01088 and carcinoembryonic antigen (CEA) for LUAD diagnosis was 0.807, the sensitivity was 89.2%, and the specificity was 71.4%. The AUC for early LUAD was 0.770, the sensitivity was 86.7%, and the specificity was 71.4%. The combined diagnostic model of platelet LINC01088 and CEA was superior to CEA in the diagnosis of LUAD and early LUAD (Z=-2.288, -2.34, both P<0.05). 【Conclusion】 LINC01088 is down-regulated in platelets of LUAD patients. Platelet LINC01088 may be a biomarker for early screening and diagnosis of LUAD.

OBJECTIVE:To study the improvement effects of total ginsenosides on the senescence of PC 12 cells induced by D-galactose and its mechanism. METHODS :Rat pheochromocytoma (PC12)cells were treated with D-galactose to establish cell senescence model. CCK- 8 method was used to screen the D-galactose modeling concentration and total ginsenosides concentration. Normal control group ,model group ,total ginsenosides low and high concentration groups were set up. Cell senescence ,cell apoptosis rate ,apoptotic cycle and mitochondrial membrane potential (MMP),cell adenosine triphosphate (ATP)and reactive oxygen species (ROS)levels in each group were detected. The expression of apoptosis related proteins [B lymphoma 2(Bcl-2)and its related egg X protein (Bax),cytochrome C (Cyt-C)] and oxidative damage related proteins [nuclear factor 2 related factor 2 (Nrf2),heme oxygenase 1(HO-1)] were detected. In addition ,positive drug group [ 5 mmol/L N-acetyl-L-cysteine(NAC)] and positive control group [ D-galactose+5 mmol/L NAC] were set up to compare the levels of oxidative damage related proteins. RESULTS:D-galactose could significantly inhibit the survival rate of PC 12 cells,with a critical concentration of 20 mg/mL. The total ginsenosides could significantly increase the survival rate of D-galactose induced senescent cells with a median effective concentration(EC50)of 65 μg/mL,and then the low and high concentrations of total ginsenosides were set at 55 and 65 μg/mL. Compared with normal control group ,the number of aging cells increased ,the apoptotic rate and percentage of G 1 phase were significantly increased i n model group. the percentage of S phase ,MMP and ATP contents ,the protein expression of Bcl- 2 and Cyt-C in mitochondria were decreased significantly ,whileROS content ,the protein expression of Bax ,Nrf2 and Cyt-C protein in endochylema were increased significantly (P<0.05 or P<0.01). Compared with model group ,the number of E-mail:sunqiao150509@163.com aging cells reduced ,the apoptosis rates and percentage of G 1 phase were significantly decreased in total ginsenosides low and high concentration groups ,the percentage of S phase ,the contents of MMP and ATP (except for low concentration group ),protein expression of Bcl- 2,Nrf2 and HO- 1 as well as protein expression of Cyt-C in mitochondria were increased significantly ;ROS level (except for low concentration group )and Bax protein as well as protein expression of Cyt-C were decreased significantly. The protein expression of Nrf 2 and HO- 1 were increased significantly in positive control group (P<0.05 or P<0.01), but it was lower than that of total ginsenosides groups . CONCLUSIONS:Total ginsenosides can improve D-galactose induced senescence of P 12 cells,the mechanism of which may be related to activating Nrf 2 antioxidant signal pathway to antagonize D-galactose induced oxidative stress and alleviating mitochondrial dysfunction.

OBJECTIVE To systematically evaluate the efficacy and safety of transcatheter arterial chemoembolization (TACE) combined with anti-angiogenic drugs for the treatment of unresectable primary liver cancer (PLC). METHODS Retrieved from Chinese and English databases such as CNKI, the Cochrane Library, Google, and Baidu Academic, randomized controlled trial (RCT) about TACE combined with anti-angiogenic drugs for the treatment of unresectable PLC were collected from the inception to May 27, 2024. After screening the literature, extracting data, and evaluating the quality of the literature, network meta-analysis was performed using R 4.2.2 and Stata 17.0. RESULTS A total of 44 RCT were included, involving 5 607 patients and 8 interventions. The network meta-analysis results showed that for prolonging median overall survival (mOS) and median progression- free survival (mPFS), TACE+apatinib had the best efficacy, with TACE+apatinib and TACE+sorafenib ranking as the top two. For improving objective response rate (ORR) and disease control rate (DCR), TACE+donafenib had the best efficacy, with TACE+ donafenib and TACE+ lenvatinib ranking as the top two. In terms of safety, TACE+donafenib was the best, with TACE+donafenib and TACE+apatinib ranking as the top two. CONCLUSIONS TACE+apatinib and TACE+donafenib have good efficacy for patients with unresectable PLC, and TACE+donafenib has the best safety profile.
