Objective To assess the clinical value of a novel surgical technique—Tubeless subxiphoid uniportal video-assisted thoracoscopic surgery with percutaneous suspension technique via balance-shaped sternal elevation device in the resection of anterior mediastinal masses. Methods Patients who underwent tubeless subxiphoid uniportal video-assisted thoracoscopic surgery via balance-shaped sternal elevation device in anterior mediastinal masses process at the Department of Thoracic Surgery, West China Hospital, Sichuan University from March to April 2025 were included, and their clinical data were analyzed. Results A total of 4 patients were included, with 2 males and 2 females, aged 58-75 years. The diameter of the tumor was 2.5-3.0 cm. The operation time was 60.0-150.0 min, intraoperative blood loss was 5-10 mL, pain score on the 3rd day after surgery was 0 points, and postoperative hospital stay was 2-3 days. All patients achieved complete resection of the masses and thymus without perioperative complications. Conclusion The tubeless subxiphoid uniportal video-assisted thoracoscopic surgery with percutaneous suspension technique via balance-shaped sternal elevation device technique optimizes surgical visualization and instrument maneuverability while avoiding complications related to conventional anesthesia and tubing, thereby markedly enhancing the minimally invasive profile of anterior mediastinal masses resections. In addition to maintaining procedural safety, this approach effectively reduces postoperative pain and accelerates patient recovery, highlighting its potential for widespread clinical adoption.

Autophagy is a cellular self-degradation process that maintains homeostasis and has been shown to promote tumor progression in advanced stages.Pancreatic cancer cells and the surrounding stromal cells exhibit high levels of autophagy.Therefore,targeting au-tophagy has emerged as a promising therapeutic strategy for pancreatic cancer.This review focuses on research targeting autophagy in pancreatic cancer treatment,elaborating on the roles and underlying mechanisms of autophagy in pancreatic cancer cell proliferation,metas-tasis,modulation of the tumor immune microenvironment,and drug resistance.Additional-ly,we summarize preclinical and clinical studies investigating autophagy-targeted therapies both as monotherapy and in combination with other treatments,aiming to provide new theo-retical rationale and therapeutic strategies for pancreatic cancer management.

Objective To establish atopic dermatitis(AD)-like models in BALB/c mice using three chemical inducers,calcipotriol(MC903),2,4-dinitrochlorobenzene(DNCB),and oxazolone(OXA),and to explore the occurrence of ferroptosis in the different models.Methods Healthy 7-week-old female BALB/c mice were divided randomly into eight groups(n=8 mice per group)based on the induction site(ear/dorsal skin)and inducer:ear/dorsal control groups,MC903 ear/dorsal model groups,DNCB ear/dorsal model groups,and OXA ear/dorsal model groups.Models were established by topical application of the respective agents at specified concentrations.Mice in the MC903 ear/dorsal groups underwent continuous induction for 14 d.Mice in the DNCB and OXA ear/dorsal groups were sensitized for 3 consecutive days,4 days after the sensitization was completedand then challenged 12 times on day 8 and every other day for up to day 30.Skin lesions were observed and skin thickness was measured.Plasma levels of reactive oxygen species(ROS),interleukin(IL)-4,interferon(IFN)-γ,and malondialdehyde(MDA)were detected,the skin was examined by histopathological staining and ultrastructural observation,and expression levels of ferroptosis-related proteins(glutathione peroxidase 4(GPX4),ferritin heavy chain 1(FTH1),long-chain-fatty-acid-CoA ligase 4(ACSL4),transferrin receptor 1(TfR1))were detected by Western Blot.Results Compared with each control mice,all model mice exhibited obvious redness,swelling,scratching,desquamation,and rough thickening of the skin,and skin thickness was significantly increased(P＜0.01).ROS,IFN-γ,IL-4,and MDA levels were elevated to varying extents(P＜0.05)and histopathological features,including epidermal hyperplasia,keratinocyte degeneration,dermal vascular congestion,and immune cell infiltration,were detected in model mice.Transmission electron microscopy also revealed mitochondrial membrane rupture,increased density,and cristae reduction.Expression levels of ferroptosis markers were dysregulated,including significantly decreased GPX4/FTH1(P＜0.05)and increased ACSL4/TfR1 expression(P＜0.05).Conclusions All three chemicals successfully induced AD-like phenotypes in BALB/c mice through site-specific applications.Ferroptosis is involved in the pathological process of AD,but heterogeneity exists among inducers and modeling sites.

ObjectiveTo investigate the clinical efficacy of Huangqi injection combined with Buzhong Yiqi acupuncture in the treatment of chronic fatigue syndrome （CFS） with Qi deficiency and its effects on TCM syndromes， fatigue symptoms， serum superoxide dismutase （SOD）， malondialdehyde （MDA）， and oxidized low-density lipoprotein （ox-LDL） levels. MethodA total of 200 patients with CFS of Qi deficiency were randomly divided into a control group （100 cases） and an observation group （100 cases）. The control group was treated with vitamin B compounds， and the observation group was treated with Huangqi injection combined with Buzhong Yiqi acupuncture for two weeks. The scores of TCM syndromes， fatigue symptoms， levels of serum SOD， MDA， and ox-LDL and the incidence of adverse reactions were observed and compared before and after treatment in two groups. ResultAfter treatment， the total effective rate of the control group was 54.34% （50/92）， while that of the observation group was 88.54% （85/96）. The total effective rate of the observation group was higher than that of the control group （χ²=27.13，P<0.05）. Compared with those in the two groups before treatment， scores of fatigue self-assessment scale （FSAS）， physical fatigue and mental fatigue， and sleep/rest response scores of fatigue in the two groups after treatment were significantly decreased （P<0.05）. After treatment， scores of FSAS， physical fatigue and mental fatigue， and sleep/rest response scores of fatigue in the observation group were significantly decreased compared with those in the control group （P<0.05）. Compared with those in the two groups before treatment， TCM syndrome scores in the two groups after treatment were significantly decreased （P<0.05）. After treatment， TCM syndrome scores in the observation group were significantly decreased compared with those in the control group （P<0.05）. Compared with those in the two groups before treatment， MDA levels in the two groups were significantly decreased （P<0.05）， ox-LDL levels in the observation group were significantly decreased （P<0.05）， and SOD levels were significantly increased （P<0.05）. After treatment， compared with those in the control group， the serum MDA and ox-LDL levels in the observation group were significantly decreased （P<0.05）， and the serum SOD was significantly increased （P<0.05）. No serious adverse events or adverse reactions occurred during this clinical trial. ConclusionHuangqi injection combined with Buzhong Yiqi acupuncture has a good clinical curative effect in the treatment of CFS with Qi deficiency， which can effectively improve the fatigue symptoms of patients， increase the level of SOD， and reduce the level of serum MDA and ox-LDL. It is related to the production of antioxidants， inhibiting the production of lipid peroxides， and improving the body's ability to resist oxidative stress.

BACKGROUND:Reducing the rate of abnormal fertilization is an effective approach to improving the efficacy of in vitro fertilization and reducing patients'financial strain.However,the current research on abnormal fertilization has focused on exploring the types of prokaryotic nuclei and their generation mechanisms,as well as analyzing embryos formed by abnormal fertilization,chromosomal ploidy and utilization value.There is a lack of clinical prediction models for abnormal fertilization based on retrospective studies. OBJECTIVE:To construct a nomogram model to predict abnormal female factors in in vitro fertilization. METHODS:A total of 5 075 patients undergoing treatment for conventional in vitro fertilization at Nanxishan Hospital of Guangxi Zhuang Autonomous Region from March 2017 to March 2022 were retrospectively analyzed.The male confounders were calibrated on a 1:1 propensity score with a match tolerance of 0.02,and 1 672 cases were successfully matched.According to the Vienna Consensus,patients with≥60%normal fertilization capacity were included in the normal fertilization group(n=836)and those with<60%normal fertilization capacity were included in the abnormal fertilization group(n=836).The model and validation groups were obtained by random sampling at a ratio of 7:3.Factors related to the occurrence of abnormal fertilization following conventional in vitro fertilization in the model group were screened using univariate analysis and the best matching factors were selected using the Least Absolute Shrinkage and Selection Operator(LASSO)and included in a multifactorial forward stepwise Logistic regression to identify their independent influencing factors and plot a nomogram.Finally,the prediction model was validated for discrimination,accuracy and clinical application efficacy using receiver operating characteristic curves,calibration curves,clinical decision curves and clinical impact curves. RESULTS AND CONCLUSION:The univariate analysis indicated the factors influencing the occurrence of abnormal fertilization were age,controlled ovarian hyperstimulation protocol,number of assisted pregnancies,years of infertility,infertility factors,anti-mullerian hormone,sinus follicle count,basal luteinizing hormone,luteinizing hormone concentration on the human chorionic gonadotropin day,and estradiol level on human chorionic gonadotropin injection day(P<0.05).LASSO regression further identified the best matching factors,including age,microstimulation protocol,number of assisted pregnancies,years of infertility,anti-mullerian hormone,luteinizing hormone level on human chorionic gonadotropin injection day,and estradiol level on human chorionic gonadotropin injection day(P<0.05).Multifactorial forward stepwise Logistic regression results showed that age,microstimulation protocol,number of assisted conceptions,years of infertility,anti-mullerian hormone,and estradiol level on human chorionic gonadotropin injection day were independent influencing factors for the occurrence of abnormal fertilization following conventional in vitro fertilization.The receiver operating characteristic curves showed an area under the curve of 0.761(0.746,0.777)for the model group and 0.767(0.733,0.801)for the validation group,indicating that the model has good discrimination.The mean absolute error of the calibration curve was 0.044,and the Hosmer-Lemeshow test indicated that there was no significant difference between the predicted probability of abnormal fertilization and the actual probability of abnormal fertilization(P>0.05),indicating the prediction model has good consistency and accuracy.The clinical decision curves and clinical impact curves showed that the model and validation groups had the maximum net clinical benefit at valve probability values of 0.00-0.52 and 0.00-0.48,respectively,and there was a good clinical application efficacy in this valve probability range.To conclude,the nomogram model has good discrimination and accuracy as well as clinical application efficacy for predicting the occurrence of abnormal fertilization in women undergoing conventional in vitro fertilization based on age,microstimulation protocol,number of assisted conceptions,years of infertility,anti-mullerian hormone,and estradiol level on human chorionic gonadotropin injection day.

Objective:To observe the clinical efficacy and safety of Tongren Niuhuang Qingxin Pills combined with telmisartan tablets in the treatment of hypertensive vertigo syndrome of phlegm-heat disturbance.Methods:Randomized controlled trial was conducted. Totally 80 patients with hypertension vertigo and phlegm-heat disturbance syndrome were selected from March 2021 to August 2022 at Beijing Tongrentang Hospital of Traditional Chinese Medicine as the observation objects. They were randomly divided into two groups using a random number table method, with 40 cases in each group. The control group received oral telmisartan tablets, while the experimental group received Tongren Niuhuang Qingxin Pills in addition to the control group. Both groups were treated for 28 days and followed up for 1 month. The patients' room blood pressure before and after treatment was measured, and TCM syndrome scores were evaluated. The dizziness assessment rating scale (DARS) was used to evaluate the severity of dizziness, adverse reactions during treatment were recorded, drug safety was observed, and clinical efficacy was evaluated.Results:The total effective rate of the experimental group was 85.0% (34/40), and that of the control group was 7.5% (3/40), with statistical significance between the two groups ( χ2=48.32, P<0.001). Compared with before treatment, the experimental group had SBP [(136.63 ± 6.01) mmHg vs. (159.30 ± 9.01) mmHg, t=-21.00] and DBP [(84.48 ± 4.36) mmHg vs. (95.30 ± 3.75) mmHg, t=-13.80] after treatment; after treatment, SBP [(137.34 ± 6.39) mmHg vs. (158.00 ± 10.06) mmHg, t=-5.28] and DBP [(86.08 ± 4.43) mmHg vs. (95.18 ± 6.61) mmHg, t=-8.09] decreased in the control group ( P<0.01), but there was no statistical significance between the two groups after treatment ( P>0.05). After treatment, the TCM syndrome scores in the experimental group (8.68 ± 3.39 vs. 15.12 ± 3.03, Z=-6.61) were lower than those in the control group ( P<0.001), and DARS score [(8.53 ± 3.93) vs. (12.20 ± 3.95), Z=-3.63] was lower than that in the control group ( P<0.001). After treatment, the therapeutic effect index of TCM syndromes in the experimental group improved compared to before treatment in the same group. The therapeutic effect index of each symptom, from high to low, was as follows: rotation of oneself or visual objects>numbness of limbs>dry stool>dizziness and dizziness>liking cold drinks>bitter and dry mouth>red urine>red tongue, yellow coating, and greasy tongue>vomiting sticky and turbid phlegm>tinnitus>smooth pulse. There were no significant adverse reactions during the treatment of the two groups. Conclusion:Tongren Niuhuang Qingxin Pills combined with telmisartan can reduce the blood pressure of patients with hypertensive vertigo syndrome of phlegm-heat disturbance, improve the vertigo symptoms and TCM syndromes of patients, and the efficacy evaluation is superior to that of telmisartan alone.

Objective:To explore the value of adenosine loaded 99Tc m-MIBI single photon emission computed tomography (SPECT) in evaluating the therapeutic effect of nicorandil on coronary microvascular angina (CMVA). Methods:Sixty eight patients diagnosed with CMVA in the Second Affiliated Hospital of Xuzhou Medical University from January 2021 to March 2022 were selected and randomly divided into a control group and a nicorandil group, with 34 patients in each group, using a random number table method. The control group received isosorbide mononitrate in addition to conventional treatment, while the nicorandil group received nicorandil in addition to conventional treatment. Both groups were treated continuously for 3 months. All patients underwent adenosine loading 99Tc m-MIBI SPECT before and after treatment to measure the degree of myocardial perfusion defect (SDS), myocardial perfusion defect area (SRS), and degree of improvement of myocardial perfusion defect (SIS). Clinical symptoms, electrocardiogram changes, myocardial enzyme indicators [cardiac troponin I (cTnI), creatine kinase-MB (CK-MB), lactate dehydrogenase (LDH)], hemodynamic parameters [systolic blood pressure (SBP), diastolic blood pressure (DBP), heart rate (HR), stroke volume (SV), cardiac output (CO), peripheral resistance (TPR), left ventricular work index (LVWI), and myocardial oxygen consumption (MVO 2)] were evaluated. Results:After treatment, the SDS and SRS of the nicorandil group were significantly lower than those of the control group ( P<0.01), and the SIS was significantly higher than that of the control group (all P<0.01); The improvement of abnormal myocardial perfusion imaging was significantly better than that of the control group (χ 2=4.976, P<0.05); the frequency, duration, and severity of angina attacks, Canadian Heart Association (CCS) grading, and incidence of ischemic changes on electrocardiogram were all lower than those of the control group ( P<0.01); The levels of serum cTnI, CK-MB, and LDH were significantly lower than those in the control group (all P<0.01); SBP, DBP, HR, LVWI, and MVO 2 were significantly lower than those in the control group (all P<0.01), while SV and CO were significantly higher than those in the control group (all P<0.01). Conclusions:Adenosine loaded 99Tc m-MIBI SPECT can effectively evaluate the therapeutic effect of nicorandil on CMVA, and nicorandil can improve myocardial perfusion defects and clinical manifestations in CMVA patients.
