Objective: This study aimed to compare outcomes and adverse events of patients with locally advanced cervical cancer (LACC) undergoing concurrent chemoradiotherapy (CCRT) with cisplatin single-agent chemotherapy vs. CCRT with cisplatin combined with paclitaxel dualagent therapy. The primary outcomes are overall survival (OS), progression-free survival (PFS), local recurrence (LR), distant metastasis (DM) and the occurrence of adverse events. Methods: This retrospective cohort study included patients with FIGO 2009 stage IB1-IVA cervical squamous cell carcinoma undergoing radical CCRT. Patients were divided into groups A and B, treatment outcomes were compared between the two groups after 1:1 proportional propensity score matching. Results: Medical records of 1,203 patients were reviewed and 572 patients were finally included for propensity score matching. After propensity score matching, 121 pairs of patients were selected for analysis. The OS, PFS, LR and DM rates were 78.5% and 83.5% (p=0.417), 73.3% and 78.5% (p=0.312), 6.6% and 2.5% (p=0.123), 19% and 15.7% (p=0.497) for groups A and B, respectively. Further subgroup analysis according to stage and lymph node metastatic status showed no difference in survival between the two groups. The incidence of grade 3–4 acute haematological toxicities was different between the two groups (p<0.05). Conclusion Cisplatin combined with paclitaxel CCRT couldn’t improve the survival rates of patients with LACC. However, the hematological toxicity of combination chemotherapy is more severe but controllable. Cisplatin single-agent therapy remains the first choice for CCRT. Further prospective studies are indicated to provide evidence for the efficacy of cisplatin plus paclitaxel in dual-agent concurrent therapy.

AIM:This study investigates the effect of fibroblast growth factor 21(FGF21)long-acting ana-logue PF-05231023 on promoting the"browning"of white adipose tissue(WAT)by inhibiting mitophagy in WAT and the molecular mechanisms involved.METHODS:Using a high-fat diet(HFD)to replicate an obesity model in mice,18 C57BL/6J mice were divided into three groups:normal control(NC)group,HFD group,and PF-05231023 intervention(PF+HFD)group,each consisting of 6 mice.After 12 weeks of feeding,the mice were anaesthetized,their eyeballs were removed to collect blood samples,and serum was separated to measure levels of total cholesterol(TC),triglycerides(TG),low-density lipoprotein cholesterol(LDL-C)、alanine aminotransferase(ALT),and aspartate aminotransferase(AST)in mouse serum.The inguinal WAT(iWAT),epididymal WAT(eWAT)and liver were collected.Part of the tis-sues were used for Western blot experiments to measure the protein levels of"browning"related markers uncoupling pro-tein-1(Ucp-1)and peroxisome proliferator-activated receptor γ coactivator-1α(PGC-1α),as well as mitophagy-related markers PTEN-induced kinase 1(Pink1),parkin,beclin-1 and microtubule-associated protein 1 light chain 3-Ⅱ(LC3-Ⅱ).Another part of the tissues was fixed in paraformaldehyde for subsequent HE and immunohistochemical staining.3T3-L1 cells were induced to mature adipocytes using the classic"cocktail"method.The CCK-8 assay was used to assess the impact of different concentrations of PF-05231023 intervention on cell viability.After 48 h of PF-05231023 intervention,the 3T3-L1 cell clumps were collected for Western blot experiments to measure the expression levels of"browning"related markers Ucp-1 and PGC-1α,as well as mitochondrial autophagy-related markers Pink1,parkin,beclin-1,and LC3-Ⅱ proteins.Oil red O staining was performed to detect cell accumulation,and immunofluorescence staining was used to mea-sure Ucp-1 protein content.Subsequently,3T3-L1 cells were divided into the normal group,PF-05231023 intervention group,Pink1 agonist MTK458 intervention group,and MTK458+PF-05231023 intervention group.Cell clumps were col-lected for Western blot experiments to measure the markers as mentioned above.RESULTS:The key findings of our study indicate that the PF-05231023 intervention did not affect energy intake in mice but significantly reduced the weight,liver weight,and fat weight of mice induced by a high-fat diet(P<0.05).The intervention also decreased lipid accumula-tion(TC,TG、LDL-C)and liver damage(ALT,AST)and alleviated hepatocyte vacuolization and adipocyte size(P<0.05).Compared with the HFD group,the PF-05231023 intervention increased the levels of Ucp-1 and PGC-1α protein expression in iWAT and eWAT(P<0.01).Immunohistochemical staining showed higher Ucp-1 protein content in the PF-05231023 intervention group than in the HFD group.The PF-05231023 intervention dose-dependently increased Ucp-1 and PGC-1α protein expression levels in mature 3T3-L1 cells(P<0.01),reduced cellular lipid accumulation,and immu-nofluorescence staining showed increased Ucp-1 protein content in mature 3T3-L1 cells after PF-05231023 intervention.The PF-05231023 intervention inhibited mitochondrial autophagy-related indicators Pink1,parkin,beclin-1,and LC3-Ⅱ protein expression levels in iWAT,eWAT,and induced mature 3T3-L1 cells(P<0.05).The MTK intervention increased Pink1,parkin,beclin-1,and LC3-Ⅱ protein expression levels,increased Ucp-1 protein expression level,compared with the MTK intervention group,after MTK and PF-05231023 co-intervention,partially decreased Pink1,parkin,beclin-1,and LC3-Ⅱ protein expression levels,and partially restored Ucp-1 protein expression level(P<0.01).CONCLUSION:(1)Intervention with PF-05231023 can improve obesity and related metabolic disorders induced by a high-fat diet in mice;(2)PF-05231023 intervention can inhibit white adipose tissue(WAT)and induce mature 3T3-L1 cell mitochondria autophagy,promoting"browning"by inhibiting mitochondrial autophagy;(3)Its mechanism may be related to the inhibi-tion of the Pink1-parkin signalling pathway.

AIM:To explore the correlation between trimethylamine-N-oxide(TMAO)and type 2 diabetic kidney disease(DKD),and to provide new ideas for the early clinical diagnosis of DKD.METHODS:A total 246 patients with type 2 diabetes mellitus(T2DM)ad-mitted to the Department of Endocrinology of the First Hospital of Lanzhou University from January 1,2020 to May 31,2020 were divided into diabetic kidney disease group(DKD group)and simple diabetes mellitus group(NDKD group).According to urinary albumin/creatinine ratio(UACR),the patients were divided into A1,A2 and A3 subgroups.According to the estimated glomerular filtration rate(eGFR),the patients were divided into G1,G2,G3 and G4-5 sub-groups.According to the Kidney Disease:Improving Global Outcomes(KDIGO)guidelines,the risk of progression of DKD was assessed(low,medium,high or very high risk).General clinical data and laboratory indicators were collected.TMAO level was measured by euzymelinked immunosorbent assay.SPSS 25.0 software was used for statistical analysis.RESULTS:In T2DM patients,TMAO level was positively correlated with UACR(r=0.515,P<0.01)and negatively correlated with eGFR(r=-0.409,P<0.01).TMAO is an indepen-dent risk factor for the onset and progression of DKD.In diagnostic model,the AUROC was 0.745 with op-timal cut-off value was 5.37μmol/L.CONCLUSION:TMAO is closely related to the occurrence and de-velopment of DKD,and it has certain clinical predictive value for DKD.Therefore,TMAO may become a po-tential target for the early diagnosis and treatment of DKD.

With the increasing proportion of human papilloma virus(HPV)infection in the pathogenic factors of oro-pharyngeal cancer,a series of changes have occurred in the surgical treatment.While the treatment mode has been im-proved,there are still many problems,including the inconsistency between diagnosis and treatment modes,the lack of popularization of reconstruction technology,the imperfect post-treatment rehabilitation system,and the lack of effective preventive measures.Especially in terms of treatment mode for early oropharyngeal cancer,there is no unified conclu-sion whether it is surgery alone or radiotherapy alone,and whether robotic minimally invasive surgery has better func-tional protection than radiotherapy.For advanced oropharyngeal cancer,there is greater controversy over the treatment mode.It is still unclear whether to adopt a non-surgical treatment mode of synchronous chemoradiotherapy or induction chemotherapy combined with synchronous chemoradiotherapy,or a treatment mode of surgery combined with postopera-tive chemoradiotherapy.In order to standardize the surgical treatment of oropharyngeal cancer in China and clarify the indications for surgical treatment of oropharyngeal cancer,this expert consensus,based on the characteristics and treat-ment status of oropharyngeal cancer in China and combined with the international latest theories and practices,forms consensus opinions in multiple aspects of preoperative evaluation,surgical indication determination,primary tumor re-section,neck lymph node dissection,postoperative defect repair,postoperative complication management prognosis and follow-up of oropharyngeal cancer patients.The key points include:① Before the treatment of oropharyngeal cancer,the expression of P16 protein should be detected to clarify HPV status;② Perform enhanced magnetic resonance imaging of the maxillofacial region before surgery to evaluate the invasion of oropharyngeal cancer and guide precise surgical resec-tion of oropharyngeal cancer.Evaluating mouth opening and airway status is crucial for surgical approach decisions and postoperative risk prediction;③ For oropharyngeal cancer patients who have to undergo major surgery and cannot eat for one to two months,it is recommended to undergo percutaneous endoscopic gastrostomy before surgery to effectively improve their nutritional intake during treatment;④ Early-stage oropharyngeal cancer patients may opt for either sur-gery alone or radiation therapy alone.For intermediate and advanced stages,HPV-related oropharyngeal cancer general-ly prioritizes radiation therapy,with concurrent chemotherapy considered based on tumor staging.Surgical treatment is recommended as the first choice for HPV unrelated oropharyngeal squamous cell carcinoma(including primary and re-current)and recurrent HPV related oropharyngeal squamous cell carcinoma after radiotherapy and chemotherapy;⑤ For primary exogenous T1-2 oropharyngeal cancer,direct surgery through the oral approach or da Vinci robotic sur-gery is preferred.For T3-4 patients with advanced oropharyngeal cancer,it is recommended to use temporary mandibu-lectomy approach and lateral pharyngotomy approach for surgery as appropriate;⑥ For cT1-2N0 oropharyngeal cancer patients with tumor invasion depth＞3 mm and cT3-4N0 HPV unrelated oropharyngeal cancer patients,selective neck dissection of levels ⅠB to Ⅳ is recommended.For cN+HPV unrelated oropharyngeal cancer patients,therapeutic neck dissection in regions Ⅰ-Ⅴ is advised;⑦ If PET-CT scan at 12 or more weeks after completion of radiation shows intense FDG uptake in any node,or imaging suggests continuous enlargement of lymph nodes,the patient should undergo neck dissection;⑧ For patients with suspected extracapsular invasion preoperatively,lymph node dissection should include removal of surrounding muscle and adipose connective tissue;⑨ The reconstruction of oropharyngeal cancer defects should follow the principle of reconstruction steps,with priority given to adjacent flaps,followed by distal pedicled flaps,and finally free flaps.The anterolateral thigh flap with abundant tissue can be used as the preferred flap for large-scale postoperative defects.

Irinotecan (CPT11) chemotherapy-induced diarrhea affects a substantial cancer population due to β-glucuronidase (Gus) converting 10-O-glucuronyl-7-ethyl-10-hydroxycamptothecin (SN38G) to toxic 7-ethyl-10-hydroxycamptothecin (SN38). Existing interventions primarily address inflammation and Gus enzyme inhibition, neglecting epithelial repair and Gus-expressing bacteria. Herein, we discovered that dehydrodiisoeugenol (DDIE), isolated from nutmeg, alleviates CPT11-induced intestinal mucositis alongside a synergistic antitumor effect with CPT11 by improving weight loss, colon shortening, epithelial barrier dysfunction, goblet cells and intestinal stem cells (ISCs) loss, and wound-healing. The anti-mucositis effect of DDIE is gut microbiota-dependent. Analysis of microbiome profiling data from clinical patients and CPT11-induced mucositis mice reveals a strong correlation between CPT11 chemotoxicity and Gus-expressing bacteria, particularly Enterococcus faecalis (E. faecalis). DDIE counters CPT11-induced augmentation of E. faecalis, leading to decreased intestinal Gus and SN38 levels. The Partial Least Squares Path Model (PLS-PM) algorithm initially links E. faecalis to dysregulated epithelial renovation. This is further validated in a 3D intestinal organoid model, in which both SN38 and E. faecalis hinder the formation and differentiation of organoids. Interestingly, colonization of E. faecalis exacerbates CPT11-induced mucositis and disturbs epithelial differentiation. Our study unveils a microbiota-driven, epithelial reconstruction-mediated action of DDIE against mucositis, proposing the 'Gus bacteria-host-irinotecan axis' as a promising target for mitigating CPT11 chemotoxicity.

Lung cancer is a major cause of cancer-related mortality worldwide. Among patients with non-small cell lung cancer (NSCLC), approximately 3%-7% harbor anaplastic lymphoma kinase (ALK) gene fusions. In recent years, multiple tyrosine kinase inhibitors (TKIs) have significantly improved the survival of patients with metastatic ALK-positive NSCLC. However, disease progression due to resistance remains a challenge. This article retrospectively analyzes a case of advanced lung adenocarcinoma with the echinoderm microtubule associated protein like 4 (EML4)-ALK fusion variant 3 (V3). The patient developed resistance to Lorlatinib treatment accompanied by mesenchymal-epithelial transition factor (MET) amplification. Effective tumor control was achieved with the combined use of Crizotinib and Lorlatinib, providing a valuable reference for further exploration of treatment strategies following resistance to ALK-TKIs in clinical practice.

OBJECTIVE: To observe the clinical effect of electroacupuncture at acupoints of yangming meridians for sarcopenia. METHODS: A total of 60 patients with sarcopenia were randomized into an observation group and a control group, 30 cases in each group. In the control group, conventional nutrition intervention for sarcopenia was adopted. In the observation group, on the basis of the treatment in the control group, acupuncture was applied at bilateral Binao (LI 14), Quchi (LI 11), Zusanli (ST 36), Yanglingquan (GB 34), etc.,ipsilateral Quchi (LI 11) and Zusanli (ST 36) were connected to electroacupuncture, with discontinuous wave, 2 Hz in frequency, 1-10 mA in intensity, 2 times a week, with a interval of 3 days. A total of 12-week treatment was required in the two groups. Before and after treatment, the appendicular skeletal muscle mass index (ASMI), grip strength, 6 m-walking time, body fat percentage and body moisture percentage were observed in the two groups. RESULTS: Compared with those before treatment, after treatment, ASMI and grip strength were increased while 6 m-walking time was shortened in the two groups (P<0.05); body fat percentage was decreased while body moisture percentage was increased in the observation group (P<0.05). After treatment, in the observation group, ASMI, grip strength and body moisture percentage were increased (P<0.05), 6 m-walking time was shortened and body fat percentage was decreased (P<0.05) compared with those in the control group. CONCLUSION Electroacupuncture at acupoints of yangming meridians can effectively improve the skeletal muscle mass, muscle function, body fat percentage and body moisture percentage in patients with sarcopenia, and make the distribution of muscle and fat more reasonable.
