The recombinant human thyroid-stimulating hormone (rhTSH) can be used for differentiated thyroid cancer (DTC) preparation before ¹³¹I therapy, and follow-up. Since its approval by the American Food and Drug Administration (FDA) in 1998, rhTSH has been clinically used in European countries, the United States, and other countries for nearly 30 years. In April 2024, China’s first independently developed rhTSH agent was approved. Based on clinical experience and evidence from domestic and international studies, an expert consensus on the application of rhTSH has been developed following thorough consultations among experts. The consensus offers evidence-based recommendations to guide the appropriate use of rhTSH in clinical practice.

Objective To explore the relationship between systemic inflammatory response index(SIRI),Heidelberg pancreatic cancer prognosis(HELPP)score,controlled nutritional status(CONUT)score and the related clinicopathological characteristics and survival prognosis of patients after radical resection of pancreatic head cancer,and to build a survival prediction model and evaluate its efficacy.Methods A retrospective analy-sis was conducted on the clinical and pathological data of 169 patients diagnosed with pancreatic head cancer and undergoing radical pancreaticoduodenectomy at the Department of Hepatobiliary Pancreatic Spleen Sur-gery in Inner Mongolia Medical University Affiliated Hospital from January 1,2011 to June 30,2021.Multiva-riate COX regression analysis was used to conduct a proportional hazards model for univariate and multivariate analysis of prognostic factors affecting the overall survival of patients with pancreatic head cancer after surger-y.A prognostic column chart was constructed using R4.2.2.Results The median survival time of 169 pa-tients was 20.8 months,and the cumulative survival rates at 1,2,and 3 years after surgery were 71.6％,38.5％,and 15.4％,respectively.Patients with SIRI ≥1.74,HELPP score＞3,and CONUT score ≥3 had worse prognosis.Multivariate COX regression analysis revealed that TNM staging,tumor maximum diame-ter,carbohydrate antigen(CA)19-9,SIRI,HELPP score,and CONUT score were all independent risk factors affecting prognosis(P＜0.05).The prognostic column chart constructed based on this had good predictive performance.Conclusion SIRI,HELPP score and CONUT score are potential indicators for predicting the prognosis of patients after radical resection of pancreatic head cancer.TNM staging,maximum tumor diame-ter,CA19-9,SIRI,HELPP score,and CONUT score are independent risk factors affecting the prognosis of pancreatic head cancer.The established nomogram model can predict the long-term survival of patients with pancreatic head cancer.

Objective To explore the relationship between dynamic contrast-enhanced magnetic resonance imaging(DCE-MRI)and clinical pathological features of invasive breast cancer and lymphovascular invasion(LVI).Methods Imaging and clinical pathological data were retrospectively collected from 508 patients with invasive breast cancer who underwent breast DCE-MRI at the First Medical Center of Chinese PLA General Hospital from January 2019 to August 2021.Patients were divided into the LVI-positive(LVI+)group(n=79)and LVI-negative(LVI-)group(n=429)based on postoperative pathological results.Univariate and multivariate logistic regression analyses were used to identify risk factors for LVI.Results Compared with LVI-group,LVI+group had a higher proportion of patients aged<45 years(44.3%vs.27.0%,P=0.002),non-mass-like enhancement(NME)(31.7%vs.17.7%,P=0.004),Ki-67 expression rate(40.0%vs.30.0%,P<0.001),high Ki-67 expression(94.9%vs.78.1%,P=0.001),Luminal B subtype(76.0%vs.60.1%,P=0.008),and positive axillary lymph nodes rate(72.2%vs.31.5%,P<0.001),while the proportion of Luminal A subtype was lower(2.5%vs.21.5%,P<0.001).Univariate and multivariate logistic regression analyses showed that age≥45 years(OR=0.468,95%CI 0.280-0.783,P=0.004)was an independent protective factor for LVI,while NME(OR=1.987,95%CI 1.126-3.444,P=0.016)was an independent risk factor.Compared with Luminal A subtype,patients with Luminal B subtype(OR=10.482,95%CI 3.164-64.923,P=0.001),HER-2 overexpression subtype(OR=11.571,95%CI 2.755-79.341,P=0.003)and triple-negative subtypes(OR=8.433,95%CI 1.985-57.908,P=0.009)had a higher risk of LVI.Conclusions Age≥45 years is an independent protective factor for LVI,while NME is an independent risk factor.Among molecular subtypes,patients with Luminal B,HER-2 overexpression and triple-negative subtypes have a higher risk of LVI compared with the Luminal A subtype.

Objective To compare the clinical efficacy of pulmonary artery thrombus aspiration plus catheter-directed thrombolysis and pulmonary artery thrombus aspiration plus peripheral venous thrombolysis in treating acute intermediate-high-risk pulmonary embolism.Methods The clinical data of patients with acute intermediate-high-risk pulmonary embolism,who received pulmonary artery thrombosis aspiration combined with catheter-directed thrombolysis or peripheral venous thrombolysis at the Affiliated Hospital of Nantong University and the Qidong Municipal People's Hospital from January 2017 to May 2024,were retrospectively analyzed.Based on the propensity score matching(PSM)method,the clinical efficacy of the two treatments was compared.The observation indicators included technical success rate,clinical success rate,changes in cardiopulmonary function,and incidence of complications.Results After propensity score matching,the pulmonary artery thrombosis aspiration combined with catheter-directed thrombolysis group(group A)and the pulmonary artery thrombosis aspiration combined with peripheral venous thrombolysis group(group B)had 40 patients each.In group A and group B,the technical success rate was 100％and 100％respectively,the clinical success rate was 97.5％and 87.5％respectively,and the clinical success rate was 97.5％and 87.5％respectively(P=0.201);the postoperative one-week mean oxygen partial pressure was(98.4±16.4)mmHg and(95.5±14.7)mmHg respectively(P＜0.001);the postoperative one-week mean pulmonary artery pressure was(26.3±10.5)mmHg and(28.5±11.8)mmHg respectively(P=0.005);the mean reduction value of B-type natriuretic peptide(BNP)level was(767.2±1 005.5)ng/L and(831.0±1 371.8)ng/L respectively(P＜0.001).No statistically significant difference in the incidence of surgery-related complications existed between the two groups(P＞0.05).Conclusion In treating patients with acute intermediate-high-risk pulmonary embolism,pulmonary artery thrombosis aspiration combined with catheter-directed thrombolysis is superior to pulmonary artery thrombosis aspiration combined with peripheral venous thrombolysis in better short-term efficacy.

Objective This study aimed to provide an effective scientific basis for prevention and control of cockroaches on aircrafts by identifying cockroach-carried pathogens,and assess the insecticidal efficacy of gel bait mediated cockroach control on aircrafts,to provide technical guidance for aircraft disinsection.Methods Cassette-trapping was used to trap cockroaches,and the carried pathogens were detected using bacterial cultivation techniques.The gel bait mediated killing rate was calculated after 1,7,and 30 d by field application of gel bait.Results A total of 411 cockroaches were captured,and all were identified as Blattella germanica.26 strains of pathogenic bacteria were isolated from the trapped cockroaches.The killing rates of cockroaches were 58.8％-96.3％with 1-30 day application of gel bait.Statistically significant differences were observed in cockroach killing rates on different days(χ2=58.95,P<0.01).Conclusions B.germanica carry a large variety of pathogenic bacteria and opportunistic pathogens and are thus important infectious disease carriers.Gel bait agents have proven to be very effective against cockroaches on aircrafts.

Microplastics are widely present in various environments such as water bodies,land,and atmosphere,which pose threats to the ecological environment and human health through transmission and accumulation in the food chain.The existing detection techniques for microplastics face challenges such as complex preparation procedure of samples,low efficiency in processing large batches of samples,and difficulties in handling complex samples.Therefore,there is an urgent need for rapid and efficient detection techniques suitable for complex microplastics samples in the field of environmental monitoring.Raman spectroscopy,known for its advantages such as rapidity,accuracy,high sensitivity,non-destructiveness,and non-contact,demonstrates great application potential in detection of microplastics.Deep learning,an artificial intelligence method known for its large-scale data processing,nonlinear modeling and automatic feature extraction capabilities,is receiving increasing attention in the analysis of Raman spectroscopy signals.The application of deep learning-based Raman spectroscopy has significantly improved performance indicators such as detection efficiency and accuracy.This article introduced the existing Raman enhancement techniques,summarized the deep learning methods applied in Raman spectroscopy signal analysis,reviewed the recent research and application progress of deep learning-based Raman spectroscopy in detection of microplastics,and finally discussed the challenges and future prospects of deep learning-based Raman spectroscopy in detection of microplastics.

PURPOSE: Lateral patellar compression syndrome (LPCS) is characterized by a persistent abnormally high stress exerted on the lateral articular surface of the patella due to lateral patellar tilt without dislocation and lateral retinaculum contracture, leading to anterior knee pain. The purpose of this study is to evaluate the efficacy and prognosis of lateral retinaculum release (LRR) combined with chondroplasty in the treatment of LPCS. METHODS: This retrospective study evaluated 40 patients who underwent LRR combined with chondroplasty for LPCS between 2020 and 2021. The assessment included improvement in postoperative tenderness and knee joint function. Patients were evaluated using the Lysholm, Tegner, and International Knee Documentation Committee 2000 scoring systems, as well as the visual analog scale, both preoperatively and postoperatively, with the paired comparisons analyzed using a t-test. Additionally, intraoperative observations were made regarding knee joint lesions, including cartilage damage and osteophyte formation, with analysis by the Chi-square test. RESULTS: The visual analog scale score for tenderness showed a significant decrease after surgery (p < 0.001). Evaluation of knee joint function also indicated significant improvements, as demonstrated by increased Lysholm, Tegner, and International Knee Documentation Committee 2000 scores postoperatively (p < 0.001, p = 0.011, p < 0.001, respectively). Furthermore, all LPCS patients included in the study presented with cartilage injuries and osteophyte formation. Significant differences were noted in the incidence of cartilage damage and osteophyte formation at different locations within the knee among patients with LPCS. CONCLUSION LRR combined with chondroplasty is an effective surgical approach for treating patients with LPCS, with satisfactory recovery observed at the 1-year follow-up. Additionally, the incidence of cartilage damage and osteophyte formation in LPCS patients varies significantly depending on the specific location within the knee joint.

The circadian clock is an important internal time regulatory system for a range of physiological and behavioral rhythms within living organisms. Testosterone, as one of the most critical sex hormones, is essential for the development of the reproductive system, maintenance of reproductive function, and the overall health of males. The secretion of testosterone in mammals is characterized by distinct circadian rhythms and is closely associated with the regulation of circadian clock genes. Here we review the central and peripheral regulatory mechanisms underlying the influence of circadian clock genes upon testosterone synthesis. We also examined the specific effects of these genes on the occurrence, development, and treatment of common male diseases, including late-onset hypogonadism, erectile dysfunction, male infertility, and prostate cancer.
