After being treated with acupuncture, some patients with idiopathic tinnitus may experience a short-term aggravation of tinnitus symptoms on the original basis. These symptoms can be gradually relieved and the overall condition fluctuates towards recovery. This phenomenon has brought some difficulties to patients and clinicians. Based on the academic view of TCM, "destroying pathogens and re-building balance", and in association with the existing understanding of acupuncture in modern medicine for tinnitus, this paper briefly discusses the mechanism and influencing factors of symptom fluctuation in patients with idiopathic tinnitus after acupuncture treatment in terms of both TCM and modern medicine, and proposes the future direction in the research of symptom fluctuation, so as to promote the recognition of clinicians and patients on symptom fluctuation and make rational use of its positive effects. Besides, it is hoped that more researchers will pay attention to symptom fluctuation and advance the exploration of it in academic field.

SPSS 26.0 software was used for descriptive statistics and correlation analysis.AMOS 24.0 was used to construct an intermediation model, and Bootstrap method was used for mediating effect testing.Results:(1)The score of self-worth was 101.00 (92.00, 112.00), the score of aging attitude was 92.00 (83.00, 101.75), the score of anxiety was 2.00(0, 6.00), and the score of depression was 2.00 (0, 5.00). (2)Self-worth was positively correlated with aging attitude ( r=0.67, P<0.01), while negatively correlated with anxiety ( r=-0.45, P<0.01) and depression ( r=-0.48, P<0.01). The aging attitude was negatively correlated with anxiety ( r=-0.41, P<0.01) and depression ( r=-0.41, P<0.01). Anxiety was positively correlated with depression ( r=0.71, P<0.01). (3)The indirect effect of aging attitude between self-worth and depression in the elderly was -0.016, accounting for 19.75% (-0.016/-0.081)of the total indirect effect.The indirect effect of anxiety between self-worth and depression in the elderly was -0.045, accounting for 55.56%(-0.045/-0.081) of the total indirect effect.The chain mediating effect of aging attitude and anxiety between self-worth and depression in the elderly was -0.020, accounting for 24.69%(-0.020/-0.081) of the total indirect effect. Conclusion:Aging attitude and anxiety play a chain mediating role between self-worth and depression in the elderly.

Objective To evaluate the safety and efficacy of transcatheter arterial chemoembolization(TACE)combined with lenvatinib and camrelizumab in the treatment of advanced hepatocellular carcinoma(HCC).Methods The clinical data of a total of 63 patients with advanced HCC,who received TACE combined with lenvatinib and camrelizumab(triple therapy)or TACE combined with lenvatinib(dual therapy)at the Jingmen Municipal People's Hospital of China between April 2020 and December 2021,were retrospectively analyzed.Triple therapy group had 30 patients,and dual therapy group had 33 patients.The post-treatment tumor response,disease progression-free survival(PFS),overall survival(OS),and the incidence of adverse drug reactions were recorded.Results The median follow-up period of the two groups was 14 months(range of 4-26 months).Compared with the dual therapy group,in the triple therapy group the objective response rate(ORR)was remarkably higher(83.3%vs.57.6%,P=0.026),the disease control rate(DCR)was obviously higher(93.3%vs.69.7%,P=0.039),the median PFS was significantly longer(8.0 months vs.5.0 months,P＜0.01),and the median OS was strikingly longer(24.0 months vs.12.0 months,P=0.004).No statistically significant difference in the incidence of adverse drug reactions existed between the two groups(P＞0.05).Conclusion For the treatment of advanced HCC,TACE combined with lenvatinib and camrelizumab is clinically safe and effective.(J Intervent Radiol,2024,32:57-62)

The occurrence of benign prostate hyperplasia(BPH)was related to disrupted sex steroid hormones,and metformin(Met)had a clinical response to sex steroid hormone-related gynaecological disease.How-ever,whether Met exerts an antiproliferative effect on BPH via sex steroid hormones remains unclear.Here,our clinical study showed that along with prostatic epithelial cell(PEC)proliferation,sex steroid hormones were dysregulated in the serum and prostate of BPH patients.As the major contributor to dysregulated sex steroid hormones,elevated dihydrotestosterone(DHT)had a significant positive rela-tionship with the clinical characteristics of BPH patients.Activation of adenosine 5'-monophosphate(AMP)-activated protein kinase(AMPK)by Met restored dysregulated sex steroid hormone homeostasis and exerted antiproliferative effects against DHT-induced proliferation by inhibiting the formation of androgen receptor(AR)-mediated Yes-associated protein(YAP1)-TEA domain transcription factor(TEAD4)heterodimers.Met's anti-proliferative effects were blocked by AMPK inhibitor or YAP1 over-expression in DHT-cultured BPH-1 cells.Our findings indicated that Met would be a promising clinical therapeutic approach for BPH by inhibiting dysregulated steroid hormone-induced PEC proliferation.

Objective To investigate the effect of staphylococcal nuclease and tudor domain containing 1(SND1)on the biological function of osteosarcoma cells and decipher the mechanism of SND1 in regulating fer-roptosis in osteosarcoma cells via SLC7A11.Methods Human osteoblasts hFOB1.19 and osteosarcoma cell lines Saos-2,U2OS,HOS,and 143B were cultured,in which the expression level of SND1 was determined.Small in-terfering RNA was employed to knock down the expression of SND1(si-SND1)in the osteosarcoma cell line HOS and 143B.The CCK8 assay kit,colony formation assay,and Transwell assay were employed to examine the effect of SND1 expression on the biological function of osteosarcoma cells.Furthermore,we altered the expression of SND1 and SLC7A11 in osteosarcoma cells to investigate the effect of SND1 on osteosarcoma ferroptosis via SLC7A11.Results The mRNA and protein levels of SND1 in Saos-2,U2OS,HOS,and 143B cells were higher than those in hFOB1.19 cells(all P<0.01).Compared with the control group,transfection with si-SND1 down-regulated the expression level of SND1 in HOS and 143B cells(all P<0.01),decreased the viability of HOS and 143B cells,reduced the number of colony formation,and inhibited cell invasion and migration(all P<0.001).The ferroptosis inducer Erastin promoted the apoptosis of HOS and 143B cells,while the ferroptosis inhibitor Fer-rostatin-1 improved the viability of HOS and 143B cells(all P<0.001).After SND-1 knockdown,Erastin reduced the viability of HOS and 143B cells,while Ferrostatin-1 restored the cell viability(all P<0.001).After treatment with Erastin in the si-SND1 group,the levels of iron and malondialdehyde were elevated,and the level of glutathione was lowered(all P<0.001).The results of in vivo experiments showed that SND1 knockdown inhibited the mass of the transplanted tumor in 143B tumor-bearing nude mice(P<0.001).Knocking down the expression of SND1 resul-ted in down-regulated SLC7A11 expression(all P<0.001)and increased ferroptosis in HOS and 143B cells(P<0.001,P=0.020).Conclusions SND1 presents up-regulated expression in osteosarcoma cells.It may inhibit ferrop-tosis by up-regulating the expression of SLC7A11,thereby improving the viability of osteosarcoma cells.

Objective To investigate the effect of hairy and enhancer of split 5(HES5)on transdifferentiation and apoptosis of renal tubular epithelial cells induced by TGF-β1 and its potential mechanism.Methods The differentially expressed genes in GSE66494 data were analyzed and screened.The mouse model of unilateral uretera obstruction(UUO)was established,and the expression level of HES5 was detected in the renal tissue.HK-2 cells were treated with 10 ng/mL TGF-β1 for 24 h to establish a tubular epithelial-mesenchymal transition(EMT)model,and then qRT-PCR and Western blotting were performed to detect the expression of HES5 at mRNA and protein levels.After HK-2 cells were transfected with the plasmid overexpressing HES5,the protein levels of fibronectin,collagen Ⅰ,vimentin,apoptosis markers Bax and Bcl2 were detected in 24 h later.Then,HK-2 cells were divided into Control group,siHES5 group,TGF-β 1 group,and siHES5+TGF-β1 group.The protein level of fibrosis and apoptosis markers were measured in above groups with Western blotting.TUNEL staining and flow cytometry were employed to detect cell apoptosis.Western blotting was applied to determine the protein levels of AKT,p-AKT,PI3K and p-PI3K.HK-2 cells overexpressing HES5 were treated with PI3K inhibitor LY294002,and the expression of vimentin was detected.Results The expression of HES5 was significantly up-regulated in both chronic kidney disease(CKD)and fibrotic kidneys of mice.Overexpression of HES5 promoted the synthesis of fibronectin,collagen Ⅰ,vimentin and Bax in HK-2 cells,and inhibited the expression of Bcl2(P＜0.05).HES5 knockdown not only down-regulated the expression of fibrosis markers,but also inhibited the apoptosis of HK-2 cells.Furthermore,HES5 knockdown inhibited the activation of PI3K/AKT signaling pathway induced by TGF-β1 in HK-2 cells(P＜0.05).Inhibitors of the PI3K/AKT signaling pathway inhibitor attenuated the induction of HES5 on vimentin.Conclusion HES5 knockdown inhibits the transdifferentiation and apoptosis in TGF-β1-induced renal tubular epithelial cells,which may be related to the decreased activity of the PI3K/AKT signaling pathway.
