The incidence of papillary thyroid microcarcinoma (PTMC) is steadily rising. Although conventional thyroid surgery techniques are well-established, they present challenges such as functional impairment and overtreatment. Cellular-level fluorescence-guided imaging technology (EndoSCell^®) enables precise intraoperative tumor localization and real-time identification of neurovascular structures via high-resolution imaging and targeted labeling. This technology significantly improves surgical precision, reduces the incidence of postoperative complications including recurrent laryngeal nerve injury and hypoparathyroidism, and strengthens standards for functional preservation. This article aimed to systematically explore recent advances in the application of EndoSCell^® for PTMC management, analyze its influence on the innovation of surgical approaches and the enhancement of functional preservation criteria, and discuss future directions, thereby providing a theoretical basis for clinical practice.

Objective To evaluate the short-term efficacy of transcatheter aortic valve replacement (TAVR) using Venus A-Plus valve delivery system in patients with severe aortic stenosis. Methods The clinical data of patients undergoing TAVR in our hospital from August 2018 to March 2022 were collected and they were divided into a Venus A-Plus and a Venus A group according to the type of valve delivery system used. The perioperative data of the two groups were compared. Results A total of 121 patients were included, including 70 patients in the Venus A-Plus group [45 males and 25 females with a mean age of (67.81±6.62) years], and 51 patients in the Venus A group [33 males and 18 females with a mean age of (68.25±7.01) years]. All patients underwent TAVR, and the postoperative hemodynamic features (left ventricular ejection fraction, mean cross-valve pressure difference, peak flow rate) were significantly improved (P<0.05). There was no statistical difference in surgical success rate, all-cause mortality, conversion to thorax opening, valve-in-valve placement, moderate or above perivalvular regurgitation, new left bundle branch block or new right bundle branch block between the two groups (P>0.05). Conclusion TAVR with Venus A-Plus valve delivery system in patients with severe aortic stenosis shows comparable efficacy to the first-generation Venus A system and is satisfactory, safe and reliable.

ObjectiveThis paper aims to investigate and evaluate the staged efficacy and safety of the representative empirical prescription of the “Zhu Ke Jiao” theory， Qijia Rougan prescription， combined with entecavir in the treatment of hepatic fibrosis in chronic hepatitis B. MethodsA multicenter randomized controlled clinical study was conducted， and 101 patients diagnosed with chronic hepatitis B-related hepatic fibrosis （CHB-HF） who met the diagnosis and inclusion criteria were randomly assigned to an observation group （Qijia Rougan prescription + entecavir） and a control group （entecavir）. The treatment duration was 24 weeks. Liver stiffness measurement （LSM）， fibrosis-4 index （FIB-4）， portal vein diameter， hepatitis B serology， biochemical indicators， hepatic fibrosis markers in serum ［hyaluronic acid （HA）， laminin （LN）， procollagen Ⅲ peptide （PⅢP）， and type Ⅳ collagen （Ⅳ-C）］， and traditional Chinese medicine syndrome scores were used as efficacy evaluation indicators. Efficacy assessments and explorations of different staged subgroups of Qijia Rougan prescription were conducted according to LSM values based on the Metavir pathological staging standard. ResultsA total of 98 cases were included for statistical analysis， with 49 cases in the observation group and 49 in the control group. The general data of the patients in both groups were comparable. Compared with the same group before treatment， the observation group showed a significant reduction in LSM and FIB-4 （P<0.01）， as well as notable improvements in LN， Ⅳ-C， and various TCM syndrome scores （P<0.05， P<0.01）. When compared to the control group after treatment， the observation group demonstrated significant improvements in LSM， FIB-4， and various TCM syndrome score indicators （P<0.05， P<0.01）， indicating that the observation group performed better than the control group. Subgroup analysis of the regression of hepatic fibrosis stages showed that compared to the same group before treatment， the observation group had better improvement in regression of stages F2 and F3 （P<0.05）. When compared to the control group after treatment， the observation group exhibited superior improvement in regression of stage F3 （P<0.05）. No adverse events occurred in either group during the treatment period. ConclusionCompared with entecavir alone， the combination of Qijia Rougan prescription and entecavir significantly improves the degree of hepatic fibrosis and clinical TCM symptoms in patients. The optimal intervention period is primarily during stage F3， which is a potential “interception” point of the “Zhu Ke Jiao” theory.

Objective: Cognitive impairment is common in patients with Parkinson’s disease (PD), and few pharmacological options are available for treating this condition. We evaluated the effects of a digital cognitive training program (SUPERBRAIN), which was previously shown to be effective in populations at risk of Alzheimer’s disease, on cognitive function in individuals with PD. Methods: Twenty-three individuals with PD and mild cognitive impairment (PD-MCI) from four clinics were randomized to the intervention (n=16) or control (n=7) groups. The intervention group completed a 12-week, home-based, tablet-based cognitive training program (25–30 min/day, 7 days/week). Cognitive outcomes were assessed using the Seoul Neuropsychological Screening Battery pre- and post-intervention. Results: The adherence rate was 79.36%. The intervention group showed significant improvements in the Seoul Verbal Learning Test (SVLT) delayed recall and the Controlled Oral Word Association Test, while no changes were observed in the control group. Analysis of covariance confirmed greater SVLT improvement in the intervention group (F statistic=7.15, p=0.015, partial η2=0.28). Conclusion SUPERBRAIN is feasible and can improve cognitive function in individuals with PD-MCI.

Background and aims The mechanism of cholestatic liver injury (CLI) is unclear, and effective therapies are lacking. While peroxisome proliferator-activated receptor alpha (PPARα) agonists show potential hepatoprotective effect and pyroptosis is implicated in hepatocellular damage, how PPARα activation mitigates lithocholic acid (LCA)-induced pyroptosis remains unknown. Methods The hepatoprotective effect of PPARα agonists was evaluated in a mouse model of intrahepatic cholestasis induced by LCA. Liver injury was assessed via serum biochemistry, hematoxylin and eosin and TUNEL staining, and electron microscopy. Pyroptosis pathways were analyzed using real-time quantitative polymerase chain reaction, Western blot, and co-immunoprecipitation. Results Combined morphological, histopathological, and biochemical analyses confirmed that PPARα activation protects against CLI. Compared with LCA treatment alone, PPARα activation significantly attenuated the elevation of serum lactate dehydrogenase (LDH), the increased TUNEL-positive cells, and the formation of hepatocyte membrane pores. Mechanistically, PPARα activation suppressed both NOD-like receptor protein 3 (NLRP3) inflammasome-mediated pyroptosis and apoptosis protease-activating factor-1 (APAF-1)/CASPASE-3/GSDME-mediated pyroptosis. Furthermore, PPARα agonist pretreatment inhibited activation of the nuclear factor-kappa B (NF-κB) and forkhead box O1 (FOXO1) signaling pathways. Conclusions PPARα protects against LCA-induced CLI by inhibiting both NLRP3 inflammasome-mediated pyroptosis associated with NF-κB and APAF-1/CASPASE-3/GSDME-mediated pyroptosis associated with the FOXO1 signaling pathway.

IgA vasculitis is a common childhood vasculitis disorder.Its primary clinical manifestation is cutaneous purpura,which is often accompanied by gastrointestinal and joint symptoms.Renal involvement can present as hematuria or proteinuria.This condition is recurrent and protracted,significantly affecting the health of children.The pathogenic factors in pediatric IgA vasculitis are diverse."Wind-toxin damaging collaterals"is presented as the core pathogenesis based on clinical practice and theoretical exploration.This concept essentially entails the latent attack of wind-toxin,collateral damage leading to blood extravasation,and healthy qi deficiency and lingering toxins,with the disease primarily located in the collateral vessels.The disease course is divided into three stages:acute,lingering,and recovery.Clinical practice should adhere to the pathogenesis principles and apply stage-based pattern differentiation and treatment.The acute stage involves wind-toxin attacking collaterals with dampness-heat accumulation.Treatment focuses on dispersing wind,clearing heat,and eliminating dampness to expel wind-toxin from the muscular exterior.The self-prescribed Qufeng Xiaodian Formula is a frequently selected modified formula.The lingering stage features latent wind-toxin in the collaterals and congealed accumulations in the kidney collaterals.Treatment aims to resolve wind-toxin,disperse stasis,and eliminate accumulation to remove densely accumulated wind-toxin.A modified Taohong Siwu Decoction is selected.The recovery stage involves deficient healthy qi with persistent wind assault and lingering toxins.Emphasis should be placed on cultivating the fundamental,strengthening the root,and nourishing yin,as well as supporting the healthy qi to dispel wind and expel toxins,while conditioning the body to prevent recurrence.A modified Guomin Decoction is selected.Clinical application emphasizes the combination of characteristic medicines,such as wind medicines to expel pathogens,insect medicines to identify collaterals,and vine medicines to unblock the meridians,to enhance the effects of identifying wind,resolving toxins,unblocking collaterals,and dispersing congealed accumulations.This study aims to systematically elaborate on the stage-based treatment strategy from the perspective of"wind-toxin damaging collaterals,"providing a theoretical basis and clinical practice reference for the traditional Chinese medicine diagnosis and treatment of pediatric IgA vasculitis.

Objective To investigate the relationship between C-reactive protein(C-RP)/albumin ratio(CAR)and peripheral artery disease(PAD)in elderly patients with type 2 diabetes mellitus(T2DM).Methods A total of 150 elderly patients with T2DM hospitalized in the Department of Endocrinology of our hospital were enrolled in this study from December 2022 to December 2023 and divided into PAD group with ankle brachial index(ABI)≤0.9(n=78)and T2DM group with ABI>0.9(n=72).The general data,biochemical indicators and CAR were compared between the two groups.Pearson correlation analysis was used to analyze the correlation between CAR and each biochemical index.Logistic regression analysis was used to explore the influencing factors for PAD in T2DM patients.Receiver operator characteristic(ROC)curve was used to evaluate the predictive value of CAR for PAD.Results Age,DM duration,body mass index,systolic blood pressure,diastolic blood pressure,C-RP,white blood cell count,fasting plasma glucose(FPG),total cholesterol(TC),triglycerides(TG),blood uric acid,low density lipoprotein cholesterol(LDL-C),and blood urea nitrogen(BUN),CAR was higher(P<0.05),while albumin,high density lipoprotein cholesterol(HDL-C),and ABI were lower in the PAD group than in the T2DM group(P<0.05).Pearson correlation analysis showed that CAR was positively correlated with FPG,TG,and BUN(P<0.05),and negatively correlated with HDL-C and ABI(P<0.05).Logistic regression analysis showed that CAR(OR 1.594,95%CI 1.236～2.062),TC(OR 1.070,95%CI 1.017～1.130),TG(OR 1.101,95%CI 1.021～1.184),HDL-C(OR 0.883,95%CI 0.813～0.965),LDL-C(OR 1.090,95%CI 1.012～1.186),FPG(OR 1.065,95%CI 1.020～1.104)were influencing factors for the occurrence of PAD in elderly patients with T2DM.ROC curve analysis showed that the area under the curve of CAR was 0.82 for predicting PAD in elderly patients with T2DM,the cut-off value was 0.35,the sensitivity was 78%,and the specificity was 85%.Conclusions CAR is correlated with ABI in elderly patients with T2DM.Given CAR is an influencing factor for the occurrence of PAD,it may serve as a potential predictor for PAD development in this population.

Objective To explore the value of 3D printing technology in transcatheter aortic valve replacement(TAVR)for bicuspid aortic stenosis.Methods We retrospectively analyzed the clinical data of patients who underwent TAVR for bicuspid aortic stenosis at the Department of Cardiac Surgery of the Second Hospital of Hebei Medical University between January 2020 and January 2023.Seven-ty patients were divided into 3D printing and non-3D printing groups of 35 each,based on whether or not 3D printing technology was applied,and the perioperative clinical data of the two groups were compared.Results The patients' postoperative symptoms signifi-cantly improved compared with those before the operation,and the left ventricular ejection fraction increased to varying degrees.Compared with the non-3D printing group,the operation time,X-ray irradiation time.and transvalvular time in the 3D printing group were signifi-cantly shortened,and the probabilities of the occurrence of postoperative"flap-to-flap"implantation and conduction block were signifi-cantly reduced,with statistically significant differences(P＜0.05).There was no statistically significant difference(P＞0.05)in the inci-dence of moderate and above perivalvular leakage,valve displacement,or conversion to thoracotomy between the two groups after surgery.Conclusion 3D printing technology can effectively guide the TAVR treatment of bicuspid aortic stenosis.While significantly shortening the operation time,it can effectively increase the success rate of TAVR and reduce the risk of adverse events,providing a new approach for the transcatheter treatment of bicuspid aortic stenosis.

Objective To identify potential quality risks of Xiaoer Huatan Zhike Granules(Pediatric Phlegm-Resolving and Cough-Relieving Granules)through National Drug Sampling and Inspection,evaluate their overall quality,and propose improvements to the quality standards.Methods Samples from 34 manufacturers were tested using official standards.Exploratory methods were developed to enhance risk analysis,including thin-layer chromatography(TLC)identification,content uniformity testing,quantitative assays,and screening for unauthorized additives(e.g.,colorants).Results All batches met the official standards(100.0%compliance rate).However,deficiencies were observed:most manufacturers lacked controls for ephedrine hydrochloride content uniformity and quantification,omitted key ingredient identifications(e.g.,herbal components),and exhibited insufficient TLC specificity(e.g.,TLC of Ipecac tincture showed only one spot instead of multiple alkaloid-specific spots).Exploratory studies revealed risks in total emetine/cephaeline content,morroniside A/platycodin D content,ephedrine hydrochloride uniformity,and unauthorized colorant addition.Conclusions The overall quality of this variety is good,but the enterprise should improve the quality control measures throughout the entire process and establish stricter internal control standards;The official standards,unchanged for approximately 30 years,fail to address current regulatory requirements.The statutory quality standards need to be revised and improved.Qualitative or quantitative indicators for all drug flavors in the prescription should be added,and the content uniformity inspection of ephedrine hydrochloride should be increased.

Objective To explore the clinical effect of applying an improved"outside-in"technique in hip arthroscopic surgery.Methods Totally 136 patients undergoing hip arthroscopic surgery between June 2021 and July 2023 were selected and studied retrospectively.According to their different surgi-cal approach,they were divided into a modified approach group(n=75,including 30 males and 45 fe-males,with an average age of 36±14)and a classic approach group(n=61,including 33 males and 28 females,with an average age of 31±11).Before as well as 4 weeks,3 months and 6 months after the surgery,both groups were evaluated using the visual analog scale(VAS)and Harris hip score,and observed their surgical complications.Moreover,the surgical outcomes and time of sur-gical approach establishment were compared between the two groups.Results There was no significant difference between the two groups in general information,preoperative VAS and Harris scores.More-over,no significant difference was found between the two groups in the Harris score after surgery.Compared with the classic approach group,the improved group had significantly less surgical time(49.0±16.9 min vs.66.0±13.3 min,P<0.05),without using the C-arm fluoroscopy during surgery.Moreover,in the modified approach group,the time for establishing the mid-anteriorapproach was sig-nificantly shortened(10.4±5.9 min vs.25.9±15.1 min,P<0.05),along with the traction time during surgery(66.0±13.3 min vs.49.0±16.9 min,P<0.05).Conclusion The modified"outside-in"hip ar-throscopy technique is a safe and effective surgical method,easier to operate,with shorter surgical time.
