Acupuncture-moxibustion therapy has been known to ameliorate the symptoms of functional gastrointestinal disorders (FGIDs), although its mechanism remains unclear. The paper reviews the articles on acupuncture-moxibustion therapy for FGIDs in recent 5 years, and it is revealed that acupuncture-moxibustion therapy can alleviate FGIDs symptoms through regulating gastrointestinal motility, modulating visceral hypersensitivity, improving the impaired gastric-duodenal mucosal barrier and inflammation, balancing intestinal microbiota, and adjusting the gut-brain axis. Currently, the molecular mechanism of acupuncture-moxibustion therapy remains unknown for FGIDs, the specific disease target is not identified, and the interaction among various molecules is not elucidated adequately. The researches in the future should employ advanced technologies and methodologies to comprehensively and deeply explore and clarify the mechanism of acupuncture- moxibustion therapy for FGIDs.

Objective To investigate the effect of field angle on the results of in vivo dose validation of electronic portal imaging device(EPID)in patients.Methods Design the mold test and analyze the influence of different mold thicknesses and different frame angles on the 2D γ pass rate.Twenty-three patients who un-derwent radiotherapy in the Department of Radiotherapy of Jinhua Municipal Central Hospital from January to June 2023 were selected as the research object.In vivo dose verification was carried out during treatment to obtain 2D γ pass rate using same-day sector beam CT(FBCT)of planned CT and executive image guided(IG-RT)as reference images,and the influence of field angle on pass rate was analyzed.Results When the frame angle was unchanged,the area of the shooting field was larger than 17 cm×17 cm,and the 2D γ passing rate decreased with the increase of the thickness.The frame angle had no effect on the 2D γ pass rate when the mold thickness was constant.In clinical treatment data,the passage rate of 2D γ near 0°/180° was higher than that near 90°/270°(P＜0.05),and the passage rate near 90°/270° in the FBCT group was higher than that in the IGRT group(P＜0.05).The median passing rate of 3 mm 2D γ was 97.97％in 3％of the 23 patients.The non-IGRT group was 96.81％,the IGRT group was 97.89％,the FBCT group was 98.94％.There was a statistically significant difference in 2D γ passing rate between the non-IGRT group and the IGRT group(Z=-5.083,P＜0.05),and there was a statistically significant difference in 2D γ passing rate between the IGRT group and the FBCT group(Z=-10.657,P＜0.05).Conclusion Clinically,the difference of pass rate in vi-vo dose verification at different rack angles is mainly due to the difference of images within and between ses-sions.Using same-day FBCT as the reference image for in-vivo dose verification can improve the accuracy of pass rate and eliminate the influence of image difference between sessions.

Coronary restenosis is an important cause of poor long-term prognosis in patients with coronary heart disease. Here, we show that lysine methyltransferase SMYD2 expression in the nucleus is significantly elevated in serum- and PDGF-BB-induced vascular smooth muscle cells (VSMCs), and in tissues of carotid artery injury-induced neointimal hyperplasia. Smyd2 overexpression in VSMCs (Smyd2-vTg) facilitates, but treatment with its specific inhibitor LLY-507 or SMYD2 knockdown significantly inhibits VSMC phenotypic switching and carotid artery injury-induced neointima formation in mice. Transcriptome sequencing revealed that SMYD2 knockdown represses the expression of serum response factor (SRF) target genes and that SRF overexpression largely reverses the inhibitory effect of SMYD2 knockdown on VSMC proliferation. HDAC3 directly interacts with and deacetylates SRF, which enhances SRF transcriptional activity in VSMCs. Moreover, SMYD2 promotes HDAC3 expression via tri-methylation of H3K36 at its promoter. RGFP966, a specific inhibitor of HDAC3, not only counteracts the pro-proliferation effect of SMYD2 overexpression on VSMCs, but also inhibits carotid artery injury-induced neointima formation in mice. HDAC3 partially abolishes the inhibitory effect of SMYD2 knockdown on VSMC proliferation in a deacetylase activity-dependent manner. Our results reveal that the SMYD2-HDAC3-SRF axis constitutes a novel and critical epigenetic mechanism that regulates VSMC phenotypic switching and neointimal hyperplasia.

Aim To observe the effects of Wenfei Jiangzhuo formula(WFJZF)on rats with vascular de-mentia and investigate its possible mechanism of ac-tion.Methods Thirty-six healthy male SD rats were randomly divided into the sham group,model group,donepezil group,and low-dose,medium-dose and high-dose groups of Wenfei Jiangzhuo formula,with six rats per group.Except for the sham group,the other groups were prepared as VaD models,and each group was gavaged with the corresponding drugs after suc-cessful modeling,and tests were performed after three weeks of treatment.Behavioral,hippocampal CA1 area morphology,neural dendrites and mitochondrial chan-ges were observed in all groups of rats,and phospho-glycerate mutase 5(PGAM5),dynamics-related pro-teins1(Drp1),opticatrophyprotein-1(OPA1),and other proteins were detected in each group.Results Compared with the sham group,rats in the model group and each intervention group had prolonged es-cape latency(P＜0.05),a shorter number of travers-als across the platforms(P＜0.05),a sparse morphol-ogy of hippocampal neurons,a reduction in the number of secondary dendritic spines,and a rupture of the out-er membrane of the mitochondria;the expression of the PGAM5 and Drp1 proteins in hippocampal tissues was elevated(P＜0.05),and the expression of the OPA1 and Mfn1/2 protein expression decreased(P＜0.05);compared with the model group,donepezil group and Wenfei Jiangzhuo formula high-dose group of rats had shorter evasion latency(P＜0.05),increased number of times to traverse the platform(P＜0.05),increased number of hippocampal neurons,tightly packed,more secondary dendritic structures,and reduced mitochon-drial damage;the expression of PGAM5 and Drp1 pro-teins was reduced(P＜0.05),and the expression of OPA1 and Mfn1/2 proteins was elevated(P＜0.05).Conclusions Wenfei Jiangzhuo formula can regulate the PGAM5-Drp1 signaling axis to improve the balance of mitochondrial homeostasis,thus improving the cog-nitive condition of the brain and exerting cerebroprotec-tive effects.

Three novel sesquiterpenoid heterodimers,designated as auckcostusolides A-C(1-3),were isolated from Aucklandia costus leaves.The structures of compounds 1-3 were elucidated through comprehensive spectroscopic analysis,with their absolute configurations established using a combination of X-ray single-crystal diffraction and electronic circular dichroism(ECD)calculations.Notably,compounds 1 and 2,despite sharing identical planar structures derived from two identical sesquiterpenoids,exhibited oppos-ite configurations at C-11 and C-8'.This configurational difference can be attributed to distinct Diels-Alder cycloaddition processes between the sesquiterpenoid monomers.Additionally,the cytotoxic effects of compounds 1-3 were evaluated against colorectal can-cer HCT116 cells,fibrosarcoma HT1080 cells,and hepatocellular carcinoma HepG2 cells.Compounds 1-3 induced cell death was characterized by endoplasmic reticulum(ER)swelling and cytoplasmic vacuolization,typical morphological changes associated with paraptosis.Mechanistic studies revealed that compounds 1 and 3 triggered paraptosis-like cell death through the accumulation of react-ive oxygen species(ROS),activation of ER stress,and stimulation of the MAPK signaling pathway.

Results:Compared with DU145 group, the number of cells in Schisandrin A L, M, H groups and Simvastatin group decreased, and the cells gradually shrunk and the spacing became larger, the cell survival rate [(100.00±0.00)%, (88.41±9.36)%, (62.34±7.31)%, (42.57±5.01)%, (45.47±5.65)%], migration [(90.11±13.43)%, (74.16±8.08)%, (57.53±7.34)%, (41.34±6.79)%, (43.44±5.26)%] and invasion [(89.01±10.31)%, (73.11±9.23)%, (55.62±7.67)%, (41.13±6.35)%, (40.36±5.68)%], and the expression of p-YAP/YAP protein (0.98±0.08, 0.83±0.11, 0.69±0.07, 0.55±0.07, 0.53±0.05) were significantly decreased, the apoptosis rate [(2.88±0.34)%, (5.20±0.57)%, (8.37±0.94)%, (12.71±1.58)%, (12.03±2.21)%] and the expression of p-MST1/MST1 (0.41±0.04, 0.53±0.07, 0.75±0.07, 0.89±0.08, 0.88±0.07] and p-LATS1/LATS1 protein (0.40±0.04, 0.52±0.06, 0.64±0.06, 0.77±0.08, 0.79±0.08) were significantly increased, and the differences were statistically significant ( P<0.05). Conclusion:Schisandrin A may inhibit the proliferation of prostate cancer cell and promote cell apoptosis by inhibiting Hippo-YAP signaling pathway.

Purpose To explore the value of contrast-enhanced ultrasound(CEUS)in the differential diagnosis of gallbladder polypoid lesions(GPLs)(diameter≥10 mm).Materials and Methods A prospective enrollment of 229 patients with GPLs who underwent cholecystectomy in 17 hospitals from December 1 2021 to June 30 2024 was conducted to analyze the relationship between general data,conventional ultrasound,CEUS characteristics and the nature of GPLs.Multivariate Logistic regression was employed to identify independent risk factors for neoplastic polyps,the differential diagnostic value of different indicators was compared.Results Among 229 patients with GPLs,there were 108 cases of cholesterol polyps,102 cases of adenoma and 19 cases of gallbladder cancer.Age(Z=-4.476,P<0.001),polyp number(χ2=15.561,P<0.001),diameter(Z=-8.149,P<0.001),echogenicity(χ2=9.241,P=0.010),vascularity(χ2=23.107,P<0.001),enhancement intensity(χ2=47.610,P<0.001),enhancement pattern(χ2=6.468,P=0.011),vascular type(χ2=84.470,P<0.001),integrity of gallbladder wall(χ2=7.662,P=0.006)and stalk width(Z=-9.831,P<0.001)between cholesterol polyps and neoplastic polyps were statistically significant.Age,location,diameter,echogenicity,enhancement pattern,vascular type and stalk width between adenoma and gallbladder cancer were statistically significant(Z=-4.333,-3.902,-5.042,all P<0.05).Multivariate Logistic regression analysis showed that hyper-enhancement,branched vascular type and stalk width were independent risk factors for neoplastic polyps(OR=4.563,5.770,3.075,all P<0.001).The combination of independent risk factors was better than single factor and diameter in the differential diagnosis of cholesterol polyps and neoplastic polyps(all P<0.01).Conclusion CEUS can effectively identify the nature of GPLs and provide a valuable imaging reference for the selection of treatment methods.

OBJECTIVE: In this study, the results of forward and reverse blood typing of a male patient diagnosed as bronchiectasis were inconsistent, which were type O and type A respectively. Multiple experiments including genotyping and sequencing and family investigation were carried out to determine the subtype of ABO blood group and explore the serological characteristics of this subtype. METHODS: Standard serological techniques were used to conduct forward and reverse typing, reverse blood typing enhancement test, H antigen identification, absorption-elution test, salivary blood group substances test, and PCR-SSP method for ABO genotyping and exon 6 and 7 sequencing. RESULTS: The proband's blood group was type O by forward typing, but antigen A could be detected by absorption-elution test, anti-A1 could be detected by reverse blood typing enhancement test, it was found that there was substance H but no substance A in saliva, and the serological characteristics were consistent with Ael subtype. Gene sequencing analysis showed that there was a c.625T>G base substitution on the basis of A102, which had never been reported before. Family survey showed that c.625T>G base substitution appeared in three generations of the family. CONCLUSION In this study, a new subtype A with Ael serological characteristics caused by c.625T>G mutation was identified. c.625T>G base substitution results in the weakening of A antigen, and this mutation can be stably passed down to future generations.
