[摘 要] 目的：探讨lncRNA DLEU2通过EZH2/H3K27me3途径调控IKKα介导甲状腺癌（TC）放射性碘抵抗的作用机制。方法：利用TCGA数据库分析TC中DLEU2的表达及其与EZH2的相关性。构建放射性碘抵抗的TPC-1细胞（RR-TPC-1细胞）模型及裸鼠移植瘤模型，通过敲低或过表达DLEU2（si-DLEU2/OE-DLEU2）、抑制EZH2（UNC1999）、过表达IKKα（OE-IKKα）进行干预，采用qPCR、WB、RIP、ChIP、CCK-8、流式细胞术、TUNEL染色及体内成瘤实验检测基因与蛋白表达、表观修饰、细胞增殖、凋亡及肿瘤生长。结果：TCGA分析显示，DLEU2在TC组织中显著上调（P < 0.001），与患者不良预后相关（P = 0.008 4），且与EZH2表达呈正相关（r = 0.390, P < 0.001）；RIP证实EZH2与DLEU2存在相互作用/结合（P < 0.05）。体外实验表明，敲低DLEU2可显著下调RR-TPC-1细胞中EZH2、IKKα表达及H3K27me3修饰水平，抑制NF-κB通路活化（P < 0.05或P < 0.01），抑制细胞增殖、促进凋亡（均P < 0.05）。联合敲低DLEU2与抑制EZH2进一步增强上述效应，而过表达IKKα则可部分逆转上述效应（P < 0.05或P < 0.01）。体内实验进一步证实，敲低DLEU2联合抑制EZH2可显著抑制移植瘤生长，增加肿瘤细胞凋亡（均P < 0.01）；IKKα过表达则部分逆转上述抗肿瘤效应（P < 0.05或P < 0.01）。结论：lncRNA DLEU2通过招募EZH2催化H3K27me3修饰，间接激活IKKα/NF-κB信号并形成正反馈环路，介导TPC-1细胞131I抵抗。

OBJECTIVE To investigate the effects of alirocumab combined with atorvastatin on clinical efficacy and safety of patients with acute coronary syndrome （ACS） who underwent percutaneous coronary intervention （PCI）. METHODS A total of 207 patients with ACS who underwent PCI in our hospital from January 2021 to December 2023 were randomly divided into alirocumab group， ezetimibe group and control group， with 69 cases in each group. All patients received routine thrombosis prevention and antihypertensive treatment after PCI. On this basis， patients in the control group were treated with atorvastatin （20 mg/time， once a day）； patients in the ezetimibe group were treated with ezetimibe （10 mg/time， once a day） + atorvastatin （20 mg/time， once a day）； patients in the alirocumab group were treated with alirocumab （75 mg/time， once every 2 weeks） + atorvastatin （20 mg/time， once a day）. All patients in the three groups were treated for 8 weeks and followed up for another 6 months after treatment. The levels of cardiac function and lipid metabolism indices before and after treatment， as well as the occurrence of major adverse cardiovascular event （MACE） and other adverse drug reaction （ADR） during the follow-up period were compared among the three groups. RESULTS After treatment for 8 weeks， the levels of cardiac function and lipid metabolism indices in the three groups were significantly improved compared with those before treatment （P＜0.05）. Compared with the control group and ezetimibe group， the left ventricular ejection fraction in the alirocumab group was significantly increased， and the left ventricular end-diastolic diameter （LVEDD） was significantly shortened （P＜0.05）. Compared with control group， LVEDD of ezetimibe group was significantly shortened （P＜0.05）， the levels of total cholesterol， triglyceride and low-density lipoprotein cholesterol in the alirocumab group and ezetimibe group were significantly decreased （P＜0.05）. During the follow-up period， there was no significant difference in the total incidence of MACE and the total incidence of other ADR such as headache and abdominal pain among the three groups （P＞0.05）. CONCLUSIONS Alirocumab combined with atorvastatin can significantly improve cardiac function and regulate lipid metabolism indices in patients with ACS after PCI without increasing the risk of MACE or other ADR.

This research investigated the impact of Ganoderma lucidum polysaccharides(GLP) on hepatoblastoma HepG2 and Huh6 cell models, as well as KM mouse model with in situ transplanted tumors, so as to provide a theoretical basis for the clinical application of GLP. Cell viability was assessed through the CCK-8 assay, whereas cell proliferation was evaluated by using the BeyoClick~(TM)EdU-488 test. Cell apoptosis was visualized via Hochest 33258 staining, and autophagy was detected through Mrfp-GFP-LC3 dual fluorescence staining. An in situ tumor transplantation model was created by using HepG2 cells in mice, and mice were treated with normal saline and GLP of 100, 200, and 300 mg·kg~(-1) for tumor count calculation and size assessment. Hematoxylin-eosin(HE) staining was used to observe pathological changes in tumor tissue and vital organs(liver, kidney, lung, spleen, and heart). Western blot analysis was conducted to measure the protein expressions of tumor protein P53(P53), B-cell lymphoma-2(Bcl-2), Bcl-2-associated X protein(Bax), cleaved-caspase-3, Beclin-1, autophagy related protein-5(Atg-5), microtubule-associated protein-light chain-3Ⅰ(LC3Ⅰ)/LC3Ⅱ, autophagy adapter protein 62(P62), protein kinase B(Akt), p-Akt, mammalian target of rapamycin(mTOR), and p-mTOR. The in vitro experiment revealed that compared with the control group, after GLP treatment, tumor cell viability decreased significantly; apoptosis rate increased in a dose-dependent manner, and autophagic flux was inhibited. The in vivo experiments showed that compared with the model group, mice treated with GLP exhibited significantly fewer and smaller tumors. Western blot results showed that compared with the control group or model group, levels of P53, Bax, cleaved-caspase-3, Beclin-1, Atg-5, and LC3-Ⅱ/LC3-Ⅰ were significantly increased after GLP treatment, and the levels of Bcl-2, P62, p-Akt/Akt, and p-mTOR/mTOR were significantly decreased. These outcomes suggest that GLP promotes apoptosis and autophagy in hepatoblastoma cells by regulating the Akt/mTOR pathway.

This study investigates the mechanism by which Xintong Granules improve myocardial ischemia-reperfusion injury(MIRI) through the regulation of gut microbiota and their metabolites, specifically short-chain fatty acids(SCFAs). Rats were randomly divided based on body weight into the sham operation group, model group, low-dose Xintong Granules group(1.43 g·kg~(-1)·d~(-1)), medium-dose Xintong Granules group(2.86 g·kg~(-1)·d~(-1)), high-dose Xintong Granules group(5.72 g·kg~(-1)·d~(-1)), and metoprolol group(10 mg·kg~(-1)·d~(-1)). After 14 days of pre-administration, the MIRI rat model was established by ligating the left anterior descending coronary artery. The myocardial infarction area was assessed using the 2,3,5-triphenyltetrazolium chloride(TTC) staining method. Apoptosis in tissue cells was detected by the terminal deoxynucleotidyl transferase-mediated dUTP nick-end labeling(TUNEL) assay. Pathological changes in myocardial cells and colonic tissue were observed using hematoxylin-eosin(HE) staining. The levels of tumor necrosis factor-α(TNF-α), interleukin-1β(IL-1β), interleukin-6(IL-6), creatine kinase MB isoenzyme(CK-MB), and cardiac troponin T(cTnT) in rat serum were quantitatively measured using enzyme-linked immunosorbent assay(ELISA) kits. The activities of lactate dehydrogenase(LDH), creatine kinase(CK), and superoxide dismutase(SOD) in myocardial tissue, as well as the level of malondialdehyde(MDA), were determined using colorimetric assays. Gut microbiota composition was analyzed by 16S rDNA sequencing, and fecal SCFAs were quantified using gas chromatography-mass spectrometry(GC-MS). The results show that Xintong Granules significantly reduced the myocardial infarction area, suppressed cardiomyocyte apoptosis, and decreased serum levels of pro-inflammatory cytokines(TNF-α, IL-1β, and IL-6), myocardial injury markers(CK-MB, cTnT, LDH, and CK), and oxidative stress marker MDA. Additionally, Xintong Granules significantly improved intestinal inflammation in MIRI rats, regulated gut microbiota composition and diversity, and increased the levels of SCFAs(acetate, propionate, isobutyrate, etc.). In summary, Xintong Granules effectively alleviate MIRI symptoms. This study preliminarily confirms that Xintong Granules exert their inhibitory effects on MIRI by regulating gut microbiota imbalance and increasing SCFA levels.

ObjectiveTo investigate the influence of histone deacetylase 3 (HDAC3) on the occurrence, development of psoriasis-like inflammation in mice, and the relative immune mechanisms. MethodsHealthy C57BL/6 mice aged 6-8 weeks were selected and randomly divided into 3 groups: control group (Control), psoriasis model group (IMQ), and HDAC3 inhibitor RGFP966-treated psoriasis model group (IMQ+RGFP966). One day prior to the experiment, the back hair of the mice was shaved. After a one-day stabilization period, the mice in Control group was treated with an equal amount of vaseline, while the mice in IMQ group was treated with imiquimod (62.5 mg/d) applied topically on the back to establish a psoriasis-like inflammation model. The mice in IMQ+RGFP966 group received intervention with a high dose of the HDAC3-selective inhibitor RGFP966 (30 mg/kg) based on the psoriasis-like model. All groups were treated continuously for 5 d, during which psoriasis-like inflammation symptoms (scaling, erythema, skin thickness), body weight, and mental status were observed and recorded, with photographs taken for documentation. After euthanasia, hematoxylin-eosin (HE) staining was used to assess the effect of RGFP966 on the skin tissue structure of the mice, and skin thickness was measured. The mRNA and protein expression levels of HDAC3 in skin tissues were detected using reverse transcription real-time quantitative polymerase chain reaction (RT-qPCR) and Western blot (WB), respectively. Flow cytometry was employed to analyze neutrophils in peripheral blood and lymph nodes, CD4⁺ T lymphocytes, CD8⁺ T lymphocytes in peripheral blood, and IL-17A secretion by peripheral blood CD4⁺ T lymphocytes. Additionally, spleen CD4⁺ T lymphocyte expression of HDAC3, CCR6, CCR8, and IL-17A secretion levels were analyzed. Immunohistochemistry was used to detect the localization and expression levels of HDAC3, IL-17A, and IL-10 in skin tissues. ResultsCompared with the Control group, the IMQ group exhibited significant psoriasis-like inflammation, characterized by erythema, scaling, and skin wrinkling. Compared with the IMQ group, RGFP966 exacerbated psoriasis-like inflammatory symptoms, leading to increased hyperkeratosis. The psoriasis area and severity index (PASI) skin symptom scores were higher in the IMQ group than those in the Control group, and the scores were further elevated in the IMQ+RGFP966 group compared to the IMQ group. Skin thickness measurements showed a trend of IMQ+RGFP966>IMQ>Control. The numbers of neutrophils in the blood and lymph nodes increased sequentially in the Control, IMQ, and IMQ+RGFP966 groups, with a similar trend observed for CD4⁺ and CD8⁺ T lymphocytes in the blood. In skin tissues, compared with the Control group, the mRNA and protein levels of HDAC3 decreased in the IMQ group, but RGFP966 did not further reduce these expressions. HDAC3 was primarily located in the nucleus. Compared with the Control group, the nuclear HDAC3 content decreased in the skin tissues of the IMQ group, and RGFP966 further reduced nuclear HDAC3. Compared with the Control and IMQ groups, RGFP966 treatment decreased HDAC3 expression in splenic CD4⁺ and CD8⁺ T cells. RGFP966 treatment increased the expression of CCR6 and CCR8 in splenic CD4⁺ T cells and enhanced IL-17A secretion by peripheral blood and splenic CD4⁺ T lymphocytes. Additionally, compared with the IMQ group, RGFP966 reduced IL-10 protein levels and upregulated IL-17A expression in skin tissues. ConclusionRGFP966 exacerbates psoriatic-like inflammatory responses by inhibiting HDAC3, increasing the secretion of the cytokine IL-17A, and upregulating the expression of chemokines CCR8 and CCR6.

Hypoxia and aberrant activation of epidermal growth factor receptor (EGFR) are considered important features of various malignancies. However, whether hypoxia can directly trigger EGFR activation and its clinical implications remain unclear. In this study, we demonstrated that in oral cancer, a typical hypoxic tumor, hypoxia can induce chronic but constitutive phosphorylation of wild-type EGFR in the absence of ligands. Oral cancer cell lines exhibit different EGFR phosphorylation responses to hypoxia. In hypoxic HN4 and HN6 cells, ubiquitination-mediated endocytosis, lysosomal sorting, and degradation lead to low levels of EGFR phosphorylation. However, in CAL-27 and HN30 cells, a novel HIF-1α-induced long noncoding RNA (lncRNA), EUDAL, can compete with the E3 ligase/adaptor complex c-Cbl/Grb2 for binding to EGFR, stabilizing phosphorylated EGFR (pEGFR) and resulting in sustained activation of EGFR and its downstream STAT3/BNIP3 signaling. STAT3/BNIP3-mediated autophagy leads to antitumor drug resistance. A high EUDAL/EGFR/STAT3/autophagy pathway activation predicts poor response to chemotherapy in oral cancer patients. Collectively, hypoxia can induce noncanonical ligand-independent EGFR phosphorylation. High EUDAL expression facilitates sustained EGFR phosphorylation in hypoxic tumor cells and leads to autophagy-related drug resistance.

Acupuncture is an ancient treatment method used in traditional Chinese medicine and has been popularized worldwide. Over the past decade, there has been an increase in the amount of acupuncture research, mostly comprised of randomized controlled trials (RCTs) that aimed to answer the question on the efficacy of acupuncture. However, poor methodology and low replicability in these acupuncture RCTs have resulted in uncertainty about the efficacy of acupuncture. In this review, current advancements and challenges in acupuncture RCTs, regarding the methodological aspects of randomization, blinding, sham acupuncture and quality of reporting, were discussed. While there have been advancements in various aspects, current acupuncture RCTs still face pressing issues such as inadequate randomization and blinding, unviable sham acupuncture controls, and poor reporting quality. Given these limitations, this review seeks to identify the methodological problems that are responsible for these problems and to suggest solutions that could help to overcome them so as to improve the quality of future studies evaluating the efficacy of acupuncture.

Objective:To investigate the staging criteria of renal tuberculosis，and to analyze the diagnostic and therapeutic characteristics as well as prognostic outcomes at different stages.Methods:A retrospective analysis was conducted on the clinical data of 134 patients with renal tuberculosis who were admitted to the Second Hospital of Lanzhou University between January 2019 and December 2023.The study cohort included 62 males and 72 females，with a mean age of（46.63 ± 13.52）years and a mean body mass index（BMI）of（22.85 ± 3.73）kg/m 2. A total of 107 patients resided in rural areas. Sixty patients had a history of pulmonary tuberculosis. Tuberculous lesions were located in the left kidney in 72 cases and in the right kidney in 62 cases. The main presenting complaints included irritative lower urinary tract symptoms in 85 patients and systemic symptoms in 92 patients. Ureteral involvement was observed in 97 patients，bladder involvement in 32 patients，and genital involvement in 9 patients. Based on computed tomography（CT）findings，the number，extent，and degree of renal destruction caused by tuberculous lesions were comprehensively evaluated in axial，coronal，and sagittal planes. The primary staging criteria included lesion diameter（2 cm）and the proportion of renal volume involved by the lesion（one-third，one-half，and two-thirds）. Renal tuberculosis was classified into three stages and six subtypes：Stage Ⅰa，a solitary lesion with a diameter ≤ 2 cm；Stage Ⅰb，a solitary lesion >2 cm or multiple lesions confined within one-third of the renal volume；Stage Ⅱa，lesions involving more than one-third but confined within one-half of the renal volume；Stage Ⅱb，lesions involving more than one-half but confined within two-thirds of the renal volume；Stage Ⅲa，lesions involving more than two-thirds of the renal volume with a glomerular filtration rate（GFR）of the affected kidney <10 ml/min；and Stage Ⅲb，complete renal calcification，presenting as an “autonephrectomy”. Among the 134 patients included in this study，7 were classified as Stage Ⅰa，17 as Stage Ⅰb，20 as Stage Ⅱa，19 as Stage Ⅱb，62 as Stage Ⅲa，and 9 as Stage Ⅲb. The severity of hydronephrosis was graded as follows：mild，renal pelvic separation <2 cm；moderate，2-3 cm；and severe，>3 cm. Prior to treatment，the mean renal pelvic separation was（1.76 ± 0.92）cm in Stage Ⅰa，（1.69 ± 0.81）cm in Stage Ⅰb，and（1.10 ± 0.82）cm in Stage Ⅱa，corresponding to mild to moderate hydronephrosis. All 7 patients in Stage Ⅰa underwent ureteroscopic examination and double-J stent placement，combined with a 6-month short-course anti-tuberculosis regimen consisting of isoniazid，rifampicin，pyrazinamide，and ethambutol for 2 months（intensive phase），followed by isoniazid and rifampicin for 4 months（continuation phase）. Among the 17 patients in Stage Ⅰb，13 presented with hydronephrosis and underwent ureteroscopic examination and double-J stent placement in combination with 6 months of anti-tuberculosis therapy，while 4 patients with isolated renal tuberculosis received anti-tuberculosis therapy alone for 6 months.Of the 20 patients in Stage Ⅱa，4 with hydronephrosis underwent ureteroscopic examination and double-J stent placement plus 6 months of anti-tuberculosis therapy，whereas 16 underwent nephroureterectomy. All 19 patients in Stage Ⅱb underwent nephroureterectomy. Among the 62 patients in Stage Ⅲa，60 underwent nephroureterectomy，while 2 refused surgery and were treated with the 6-month short-course anti-tuberculosis regimen. Of the 9 patients in Stage Ⅲb，8 underwent nephroureterectomy；in 1 patient，surgery was not performed due to severe adhesions in the operative field，and the patient received the 6-month short-course anti-tuberculosis regimen instead. Follow-up assessments included clinical symptoms，erythrocyte sedimentation rate（ESR），serum creatinine，degree of renal pelvic separation，and imaging findings from urinary tract CT. Efficacy was evaluated according to the following criteria：Cure was defined as clinical stability with all of the following conditions：① improvement of systemic symptoms，including absence of flank pain，fever，and lower urinary tract irritative symptoms，with normalization of erythrocyte sedimentation rate（ESR）；② negative urine culture for Mycobacterium tuberculosis；and ③ complete calcification of renal lesions and/or no evidence of tuberculous lesions at other sites. Stable disease was defined as no change in the size or extent of renal tuberculosis lesions. Progressive disease was defined as enlargement or increase in the number of tuberculous lesions or involvement of additional sites. Results:Among the 7 patients in Stage Ⅰa，follow-up imaging after treatment showed a mean renal pelvic separation of（0.44 ± 0.56）cm，which was significantly reduced compared with baseline（ t = 3.909， P = 0.008）. Five patients achieved cure，1 remained stable，and 1 showed disease progression and subsequently underwent nephroureterectomy，resulting in postoperative cure. In Stage Ⅰb，among 13 patients with hydronephrosis，post-treatment imaging showed a mean renal pelvic separation of（0.8 ± 0.75）cm，a statistically significant improvement from baseline（ t = 5.633， P < 0.01）. Six patients were cured，4 remained stable，and 3 experienced disease progression and underwent nephroureterectomy. Of the 4 patients with isolated renal tuberculosis，2 were controlled，and 2 progressed and underwent nephroureterectomy. In Stage Ⅱa，among 4 patients with tuberculous hydronephrosis，post-treatment renal pelvic separation was（1.20±0.98）cm，with no significant difference from baseline（ t = -1.675， P = 0.193）；these patients underwent nephroureterectomy 1-2 years later. The remaining 16 patients without hydronephrosis underwent nephroureterectomy and were cured. All 19 patients in Stage Ⅱb underwent nephroureterectomy；17 were cured，and 2 developed ipsilateral perirenal fluid collections 3 months postoperatively，which resolved spontaneously with the standard 6-month anti-tuberculosis regimen. Among 62 patients in Stage Ⅲa，60 underwent nephroureterectomy. Of these，54 were cured；1 developed a urinary tract infection within 2 weeks postoperatively；3 showed contralateral renal disease progression at 3 months；and 1 developed ipsilateral perirenal fluid at 3 months，which resolved spontaneously with standard anti-tuberculosis therapy. One patient developed solitary kidney failure 7 months postoperatively and underwent ureteral stent placement，with disease remaining stable thereafter. Two patients refused surgery and received only anti-tuberculosis therapy；during follow-up，1 patient experienced disease progression and died of disseminated tuberculosis after 1 year，while the other developed contralateral renal involvement at 3 months and received standard 6-month therapy，with disease remaining stable. Among 9 patients in Stage Ⅲb，8 underwent nephroureterectomy and were cured. One patient，with severe adhesions precluding surgery，received anti-tuberculosis therapy alone，and disease remained stable over a 2-year follow-up. Conclusions:The CT-based staging system for renal tuberculosis proposed in this study（three stages and six subtypes）effectively reflects the severity of renal lesions and clearly delineates the clinical characteristics and prognostic outcomes at each stage. Stage Ⅰ patients treated with anti-tuberculosis drugs combined with double-J stent placement demonstrated favorable outcomes and high renal preservation rates. In contrast，Stages Ⅱ and Ⅲ patients showed poor responses to anti-tuberculosis therapy combined with drainage，with a higher risk of disease progression and relatively worse prognosis，highlighting the recommendation for early nephroureterectomy of the affected kidney.

Objective To explore strategies for further subdivision of DRG in gastrointestinal surgery cases,providing references to enhance the differentiation of DRG subgroups.Methods A total of 5 108 gastrointestinal surgery cases were selected from a tertiary grade A hospital and a tertiary hospital in Hubei Province,spanning from January 2019 to June 30,2023,and another secondary hospital's data from 2020 and 2021.It employs single factor analysis and multiple linear regression analysis to identify factors influencing case costs.Additionally,the opinions of nine clinicans were gathered regarding factors affecting resource consumption in gastrointestinal surgery cases.The four selected case groups were further subdivided considers the peak characteristics of disease costs.It compares subdivided groups with the DRG Payment Subgroups Scheme(Version 2.0).Results Groups GB1,GB2,GC1,and GC2 were subdivided into 7,4,7,and 6 DRG groups,respectively.The coefficient of variation of each subdivided DRG were reduced,homogeneity was increased,and inter-group differentiation was increased.The results were consistent with the DRG Payment Subgroups Scheme(Version 2.0).Conclusion Based on DRG grouping,the DRG groups can be further subdivided according to the peak characteristics presented by case costs.This subdivision strategy is helpful to provide new ideas for case grouping of Medicare payment.

Cytotoxic CD4⁺ T cells (CD4⁺ CTLs) represent a novel subset of T cells with cytotoxic effects. They recognize target cells in an antigen-specific manner, relying on class II major histocompatibility complex (MHC-II) interactions. CD4⁺ CTLs exert cytotoxic effects on target cells by secreting cytotoxic molecules such as granzymes, perforin, and granulysin. Recent studies have revealed their significant roles in various autoimmune diseases. This review focuses on the differentiation, phenotypic characteristics, and roles of CD4⁺ CTLs in different types of autoimmune disorders, aiming to provide new insights for the prevention and treatment of these diseases.
