ObjectiveTo evaluate the immediate effectiveness and safety of four intranasal acupuncture methods based on different intranasal localizations of Neiyingxiang （EX-HN 9） for improving nasal ventilation in patients with allergic rhinitis （AR）. MethodsA total of 120 patients with AR were randomly divided into four groups with 30 cases in each group， the agger nasi group， the inferior turbinate-alar junction group， the inferior turbinate top group， and the nasal septum group. All patients received one 20-minute session of intranasal acupuncture. The agger nasi group received acupuncture at the agger nasi site， the inferior turbinate-alar junction group at the junction of the inferior turbinate and alar cartilage， the inferior turbinate top group at the top of the inferior turbinate directly facing the nostril， and the nasal septum group at Little's area of the nasal septum. Before acupuncture and within 5 min after treatment， the assessments and measurements were performed including nasal obstruction symptom evaluation （NOSE） scale used to evaluate the severity of nasal obstruction before and after acupuncture， a nasal resistance/nasal flow analyzer applied to detect nasal airway resistance （NAR） and nasal respiration volume （NS）， the visual analogue scale （VAS） adopted to assess pain intensity. The incidence of nasal bleeding and other adverse events were recorded， and patients' willingness to receive repeat treatment was statistically analyzed. ResultsCompared with baseline within group， all four groups showed decreased NOSE scores and NAR as well as elevated NS after treatment （all P＜0.05）. Compared with the agger nasi group and the inferior turbinate-alar junction group， the inferior turbinate top group had higher NOSE scores and lower NS； the nasal septum group presented higher NOSE scores and NAR alongside lower NS （P＜0.05）. The nasal septum group yielded significantly higher VAS scores than the other three groups （P＜0.05）， with 11 cases （36.67%） of massive nasal bleeding observed， while no severe nasal hemorrhage occurred in the remaining groups. The proportions of patients willing to receive repeated intranasal acupuncture treatment were 70.00% （21/30） in the agger nasi group， 76.67% （23/30） in the inferior turbinate-alar junction group， 43.33% （13/30） in the inferior turbinate top group， and 3.33% （1/30） in the nasal septum group， respectively， with statistical significant difference among groups （χ² = 39.91， P＜0.001）. ConclusionAll four intranasal acupuncture methods can immediately improve nasal ventilation in patients with AR. The agger nasi group and inferior turbinate-alar cartilage junction group achieved superior therapeutic improvement compared with the inferior turbinate top group and nasal septum group， accompanied by better safety and higher patient acceptability.

Lung cancer constitutes the most prevalent and lethal malignant tumor in China. Approximately 85% of lung cancer diagnoses correspond to the non-small cell histological subtype [non-small cell lung cancer (NSCLC)]. Despite surgery being the mainstay for early-stage disease, postoperative recurrence remains high and adjuvant chemotherapy offers limited benefit. In recent years, targeted therapy has demonstrated substantial advantages in driver mutation-positive NSCLC. To this end, the Lung Cancer Medical Education Committee of the Chinese Medical Education Association developed guidelines based on a systematic review of evidence through November 2025, using the Grading of Recommendations, Assessment, Development and Evaluations (GRADE) approach and a modified Delphi method. Focusing on epidermal growth factor receptor (EGFR) and anaplastic lymphoma kinase (ALK), and addressing ROS proto-oncogene 1 (ROS1), B-Raf proto-oncogene serine/threonine kinase (BRAF) V600E mutation, and mesenchymal-epithelial transition factor (MET) exon 14 (METex14) skipping, the guideline covers molecular testing, neoadjuvant/adjuvant therapy, perioperative strategies, minimal residual disease monitoring, and postoperative surveillance. It defines testing requirements, specifies stage-directed and subtype-specific treatments, and standardizes minimal residual disease monitoring. These recommendations emphasize precision and feasibility to improve survival and quality of life.

Objective: Intrathyroid thymic carcinoma（ITTC） is a rare thyroid tumor that lacks typical clinical manifestations and imaging features, making preoperative diagnosis challenging.The primary treatment for ITTC is radical surgery; however, the effectiveness of adjuvant radiotherapy and chemotherapy post-surgery is not well-established. This paper presents a case of ITTC , analyzing the clinical data and correlating it with the literature to explore the clinical manifestations, diagnostic approach, treatment, and prognosis of ITTC.

Gastrointestinal (GI) cancers are a leading cause of cancer morbidity and mortality worldwide. Despite advances in treatment, cancer relapse remains a significant challenge, necessitating novel therapeutic strategies. In this study, we engineered nanobody-based chimeric antigen receptor (CAR) natural killer (NK) cells targeting cadherin 17 (CDH17) for the treatment of GI tumors. In addition, to enhance the efficacy of CAR-NK cells, we also incorporated CV1, a CD47-SIRPα axis inhibitor, to evaluate the anti-tumor effect of this combination. We found that CDH17-CAR-NK cells effectively eliminated GI cancers cells in a CDH17-dependent manner. CDH17-CAR-NK cells also exhibit potent in vivo anti-tumor effects in cancer cell-derived xenograft and patient-derived xenograft mouse models. Additionally, the anti-tumor activity of CDH17-CAR-NK cells is synergistically enhanced by CD47-signal regulatory protein α (SIRPα) axis inhibitor CV1, likely through augmented macrophages activation and an increase in M1-phenotype macrophages in the tumor microenvironment. Collectively, our findings suggest that CDH17-targeting CAR-NK cells are a promising strategy for GI cancers. The combination of CDH17-CAR-NK cells with CV1 emerges as a potential combinatorial approach to overcome the limitations of CAR-NK therapy. Further investigations are warranted to speed up the clinical translation of these findings.

Objective To explore the clinical efficacy of Liuwei Dihuang Capsules for type 2 diabetes mellitus(T2DM)with yin deficiency syndrome and the effects on intestinal flora and inflammatory factors.Methods Totally 60 patients of T2DM with yin deficiency syndrome in Dongzhimen Hospital of Beijing University of Chinese Medicine from September 2022 to June 2023 were selected as the study objects,and were divided into control group and observation group according to the method of block randomization,with 30 cases in each group.Both groups received basic treatment.The control group was given a simulated agent of Liuwei Dihuang Capsules,while the observation group was given Liuwei Dihuang Capsules.The treatment course for both groups was 4 weeks.Clinical efficacy,blood glucose levels[fasting plasma glucose(FPG),2-hour postprandial plasma glucose(2 hPG),glycated albumin(GA)],serum insulin levels[fasting insulin(FINS)and insulin resistance index(HOMA-IR)],changes in gut microbiota,and serum inflammatory cytokine levels[interleukin(IL)-6,tumor necrosis factor(TNF)-α]of both groups were compared.Results The total effective rate of the observation group(76.67%)was better than that of the control group(50.00%)(P<0.05).Compared with before treatment,the FPG,2 hPG,GA,FINS and HOMA-IR decreased in the observation group,while the FPG,2 hPG and FINS decreased in the control group(P<0.05);after treatment,the Shannon index of the observation group increased after treatment(P<0.05),and the diversity of the microbiota increased;the abundance of the microbial communities such as Coprococcus 3,Cutibacterium,Pseudomonas,Faecalibaculum,Dubosiella and Mucispirillum significantly increased(P<0.05);the abundance of Sphingomonas,Corynebacterium 1,Ileibacterium,Ruminiclostridium and other microbiota communities significantly decreased(P<0.05).Compared with before treatment,the levels of IL-6 and TNF-α in both groups were significantly reduced after treatment(P<0.01,P<0.05).After treatment,the levels of IL-6 and TNF-α in the observation group were significantly lower than those in the control group(P<0.05).Conclusion Liuwei Dihuang Capsules can effectively reduce blood glucose levels in patients of T2DM with yin deficiency syndrome,improve insulin resistance,increase gut microbiota diversity,increase beneficial bacterial abundance,reduce harmful bacterial abundance,and alleviate inflammatory cytokine levels.

Objective:This multicenter retrospective study aimed to analyze the clinicopathological features of duodenal adenocarcinoma (DA) and identify prognostic factors for postoperative survival.Methods:Demographic characteristics, clinicopathological features, treatment outcomes and survival of DA patients undergoing surgical treatment at 18 Chinese medical centers from January 2012 to December 2023 were retrospectively analyzed.Results:Among the 2 056 DA patients included, 46.8% (963) had extra-ampullary DA (EA-DA), and 53.2% (1 093) had peri-ampullary DA (PA-DA). The 1-, 3-, and 5-year overall survival (OS) rates for patients who underwent radical surgery were 93.2%, 71.0%, and 57.2%, respectively. The median overall survival was 76 months, and the median progression-free survival (PFS) was 65 months. No differences in survival were observed between the laparotomy group and minimally invasive surgery (MIS) group either before or after propensity score matching (OS: 76 vs. 75 months before PSM, P=0.986; OS: 75 vs. 75 months after PSM, P=0.602). Furthermore, there were no significant differences between-group in operation time and postoperative complications ( P＞0.05). The MIS group experienced less intraoperative blood loss and shorter hospital stays. The multivariate Cox regression analysis revealed that advanced age ( HR=1.43,95% CI:1.18-1.73), elevated carbohydrate antigen 19-9 levels ( HR=1.24,95% CI:1.02-1.51), perineural invasion ( HR=1.44,95% CI:1.14-1.81), vascular invasion ( HR=1.35,95% CI:1.07-1.71), advanced T stage (T3-4 vs. T1-2: HR=1.86,95% CI:1.49-2.31), regional lymph node metastasis ( HR=1.93,95% CI:1.58-2.36), preoperative biliary drainage ( HR=1.26,95% CI:1.04-1.53), intraoperative blood loss ( HR=1.34,95% CI:1.11-1.62), clinically significant postoperative pancreatic fistulas ( HR=1.53,95% CI:1.12-2.09), and postoperative hemorrhage ( HR=1.62,95% CI:1.14-2.29) were independent risk factors for poor prognosis after surgery (all P＜0.05). Conclusions:Radical surgery is associated with favorable overall survival among DA patients, and no difference in survival is observed between EA-DA and PA-DA patients. MIS is a reliable alternative for DA treatment.

Objective To compare the efficacy and tolerability of the novel bowel-cleansing agent TCIC-001 and the traditional polyethylene glycol (PEG) regimen for bowel preparation prior to colonoscopy. Methods Prospective inclusion of 62 patients who were scheduled to undergo colonoscopy at Zhongshan Hospital, Fudan University from July 2021 to July 2022. They were randomly divided into TCIC-001 group (n=31) and PEG group (n=31) using a random number table method. The TCIC-001 group took TCIC-001 orally, drinking water in stages, with a total liquid intake of 1 500 mL; the PEG group took PEG orally, taking it in 4 doses, with a total liquid intake of 3 000 mL. The primary endpoint indicator is the quality of intestinal hygiene evaluated by the Boston Bowel Preparation Scale (BBPS), the secondary endpoint indicators were medication adherence, medication duration, frequency of bowel movements, duration of bowel movements, and incidence of adverse events between two groups. Results No significant differences were observed in sex, age, or defecation frequency between the two groups. For efficacy, both groups achieved equivalent bowel cleanliness, with a “good preparation” rate of 93.55% and comparable BBPS score of each intestinal segment and total scores. For tolerability, the TCIC-001 group had a shorter medication duration compared to the PEG group ([48.8±25.9] min vs [82.8±28.4] min, P<0.001), a longer defecation duration ([288.6±74.0] min vs [236.5±74.3] min, P<0.001), and a lower incidence of first defecation before medication completion (9.68% vs 41.94%, P=0.004). Regarding safety, no significant differences were observed between the TCIC-001 group and the PEG group in incidences of chloride disturbances (0% vs 9.68%) and calcium disturbances (3.23% vs 6.45%), and no other adverse events. Conclusions TCIC-001 demonstrated comparable bowel-cleansing efficacy to PEG while significantly improving tolerability (reduced medication time and lower risk of premature defecation) and maintaining favorable safety.

Objective To investigate the effect of gender on prognosis after transcatheter patent foramen ovale(PFO)closure in patients with cerebral infarction or transient ischemic attack.Methods A retrospective cohort study was conducted involving patients with cerebral infarction or transient ischemic attack(TIA)who underwent PFO closure at our hospital between January 2013 and December 2023.The patients were grouped by gender,and related data were collected,including age,comorbidities,Risk of Paradoxical Embolism(RoPE)score,laboratory results,findings of transthoracic/transesophageal echocardiography(TTE/TEE),and post-procedural complications,such as device-related thrombosis(DRT),recurrent stroke,bleeding,and atrial fibrillation(AF).Results A total of 112 patients were enrolled,including 59 males and 53 females,at a mean age of 42.47±12.35 years.The females had significantly higher preoperative RoPE score than the males(6.6±1.4 vs 6.0±1.5,P=0.046),and a statistical difference was observed in the distribution of infarction sites between them(Chi-square=10.25,P=0.006),indicating that the males were prone to posterior circulation infarction.Intraoperative transthoracic echocardiography revealed a greater distance from the PFO to the aortic root in the females(9.3±2.4 mm vs 7.6±2.0 mm,P<0.001).During a median follow-up of 4 years,the male group had 1 case of myocardial infarction,1 cerebral hemorrhage,1 paroxysmal AF,2 gingival bleeding episodes,and 1 skin ecchymosis.In the female group,1 case experienced pulmonary embolism,1 paroxysmal atrial fibrillation,3 gingival bleeding episodes,2 skin ecchymoses,2 recurrent cerebral infarctions,and 2 recurrent TIAs.There was no statistical difference in overall adverse events between gender(P=0.291).Although the females had higher rates of recurrent cerebral infarction and TIA,this difference lacked statistical significance(P=0.222).Multivariate Cox regression analysis indicated that after adjusting for various potential confounding factors,such as RoPE score,age,hypertension,coronary heart disease,and other factors,gender was not an independent predictor of composite endpoint events after surgery.Conclusion Gender does not significantly affect overall prognosis after PFO closure in patients with cerebral infarction or TIA.However,females showed a trend toward higher rates of recurrent cerebral infarction and TIA.
