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.

The incidence of breast cancer remains high worldwide, which seriously threatens women's health. Many patients has benefited from the traditional way of surgery combined with drug therapy, but the drug resistance and side effects have made the treatment outcome unexpected, so new therapeutic targets for breast cancer need to be continuously discovered. In recent years, SLC7A5, as an amino acid transporter, plays a key role in metabolic reprogramming and immune microenvironment remodeling in breast cancer by regulating the uptake of glutamine and leucine. Although, the role of SLC7A5 in endocrine therapy resistance is still unclear, small molecule inhibitors targeting its function such as JPH203 have shown significant efficacies in preclinical models. This article reviews the structure and function of SLC7A5, its expression characteristics in breast cancer, and its molecular mechanism driving tumor progression, and discusses the therapeutic strategies targeting SLC7A5 and its potential for clinical translation.

Objective:To evaluate the long-term outcomes and predictors of coronary atherosclerotic lesions deemed functionally non-ischemic (quantitative flow ratio(QFR)>0.80) and deferred from intervention.Methods:This study is a post-hoc analysis of the FAVOR Ⅲ China trial, which enrolled 3 825 patients with stable or unstable angina pectoris or with myocardial infarction occurring at least 72 hours prior to screening, between December 5, 2018 and January 9, 2020 from 26 research centers in China. Coronary vessels with QFR>0.80 and without interventional treatment were analyzed in this study. The primary endpoint was 3-year target vessel revascularization. Vessels with revascularization (revascularized group) during follow-up were matched 1∶1 using propensity score matching to comparable vessels without revascularization (non-revascularized group). Multivariate Cox regression analysis was used to identify the risk factors for target vessel revascularization (TVR).Results:A total of 6 212 functionally negative vessels with deferred intervention were included in the final analysis, among which 153 vessels (2.5%) underwent TVR during a 3-year follow-up. Prior to propensity score matching, 6 059 vessels comprised the non-revascularized group. At the vessel level, compared to the non-revascularized group, the revascularized group exhibited a significantly higher proportion of males (79.1% (121/153) vs. 70.2% (4 253/6 059), P=0.018), higher body mass index ((25.6±4.0) kg/m2 vs. (24.3±5.2) kg/m2, P=0.003), and a higher prevalence of hypertension (73.9% (113/153) vs. 65.1% (3 944/6 059), P=0.025). And 152 pairs of vessels were successfully matched. Multivariate Cox regression analysis identified in-stent restenosis lesions ( HR=2.59, 95% CI 1.28-5.23, P=0.008) as an independent risk factor for target vessel revascularization. Conclusions:Coronary lesions classified as functionally non-ischemic at baseline are not entirely stable and may progress to lesions that requiring revascularization over time. In-stent restenosis emerges as a critical independent predictor of revascularization.

Objective:To investigate the risk factors associated with 90-day mortality in critically ill patients receiving continuous renal replacement therapy (CRRT), with a particular focus on the association between hypotension within the first hour of CRRT initiation and 90-day mortality after hospital admission.Methods:This study was a post hoc analysis of a prospective cohort study investigating the impact of colloid versus crystalloid priming solutions on early hemodynamics in critically ill patients undergoing CRRT. The study enrolled intensive care unit patients who received CRRT at West China Hospital of Sichuan University from January 2024 to May 2024. The data were collected including demographic characteristics, laboratory tests, CRRT-related parameters, blood pressure, heart rate, sequential organ failure assessment scores, and vasoactive-inotropic score, etc. The 90-day survival outcome after hospital admission of critically ill patients aged 18-80 years who received continuous veno-venous hemodiafiltration was used as the primary outcome indicator. A Cox proportional hazards model analysis was conducted, and the predictive ability of the model was evaluated along with the test of the proportional hazards assumption. The risk factors associated with the 90-day mortality after hospital admission of critically ill patients receiving CRRT were explored, with a particular focus on whether hypotension occurring within the first hour of CRRT initiation was one of these risk factors.Results:A total of 208 patients were included in this study. Within 90 days after hospital admission, 141 patients (67.8%) died, among whom 102 were male (72.3%) and the median age was 61.0 (50.0, 71.5) years; 67 patients (32.2%) survived, among whom 53 were males (79.1%) and the median age was 56.0 (47.0, 68.0) years. The incidence of hypotension within the first hour of CRRT initiation was significantly higher in the death group than in the survival group [29.8% (42/141) vs. 16.4% (11/67), χ2=4.275, P=0.039]. Moreover, The mortality rate of the group with hypotension within the first hour of CRRT initiation was higher than that of the group without hypotension [79.2% (42/53) vs. 63.9% (99/155), χ2=4.275, P=0.039]. The Kaplan-Meier survival analysis showed that the median survival time of patients without hypotension within the first hour of CRRT initiation [39.0 d (95% CI 23.2-54.8)] was longer than that of patients with hypotension [26.0 d (95% CI 18.9-33.1)], and the 90-day cumulative survival rate after hospital admission of patients without hypotension was significantly higher than that of patients with hypotension (Log-rank test, χ2=5.100, P=0.024). Univariate and multivariate Cox proportional hazards analyses demonstrated that serum albumin ( HR=0.964, 95% CI 0.933-0.997, P=0.030), sequential organ failure assessment score ( HR=1.064, 95% CI 1.012-1.118, P=0.015), and the use of mechanical ventilation ( HR=8.272, 95% CI 1.145-59.743, P=0.036) were significantly associated with 90-day mortality in critically ill patients undergoing CRRT. In contrast, the vasoactive-inotropic score ( HR=1.004, 95% CI 0.999-1.008, P=0.079) and the presence of hypotension within the first hour of CRRT initiation ( HR=1.236, 95% CI 0.833-1.835, P=0.293) were not significantly associated with 90-day mortality in critically ill patients undergoing CRRT. The consistency index of this model was 0.654 (95% CI 0.617-0.691), the area under the receiver operating characteristic curve was 0.724 (95% CI 0.658-0.800), and the calibration curve showed that the predicted values of the model were well fitted to the actual observations, suggesting that the predictive effect of this model was relatively ideal. Conclusions:In critically ill patients undergoing CRRT, the occurrence of hypotension within the first hour of CRRT initiation was not significantly associated with 90-day mortality after hospital admission. Lower serum albumin levels, higher sequential organ failure assessment scores, and the use of mechanical ventilation may be the risk factors for 90-day mortality in this population.

Objective:To investigate the effects of thoracolumbar vertebral fracture with incomplete spinal cord injury on male sexual function and postoperative prognosis.Methods:A retrospective review was conducted on data from 144 male patients with thoracolumbar vertebral fractures and incomplete spinal cord injuries treated between May 2009 and May 2021 in the Department of Traumatology and Orthopedics at Peking University Third Hospital. Patients ranged in age from 19 to 55 years (mean: 38.6±10.6 years) and underwent posterior incision and reduction internal fixation. The International Index of Erectile Function-5 (IIEF-5), the Premature Ejaculation Diagnostic Tool (PEDT), and the International Spinal Cord Injury Male Sexual Function Basic Data Set were used for sexual function evaluation. Based on the American Spinal Injury Association (ASIA) Spinal Cord Injury classification, changes in neurological and sexual function were assessed at the pre-injury stage, 3 months post-injury, 2 years postoperatively, and at the final follow-up. Factors influencing sexual dysfunction and recovery were analyzed. Spearman correlation analysis was used to identify factors affecting sexual function injury and recovery.Results:A total of 117 patients were included in the final analysis. Follow-up duration ranged from 26.2 to 161.7 months (mean: 74.6±40.5 months). After injury, ASIA grades were distributed as follows: 43 patients with grade B, 41 with grade C, and 33 with grade D. At the 2-year follow-up, 30 patients were grade E, 63 grade D, 19 grade C, and 5 grade B. Improvement in ASIA classification was observed in 90.6% (106/117) of patients: 79 improved by one grade, 27 by two grades, 8 remained unchanged, 1 worsened by one grade, and 2 worsened by two grades. Mean IIEF-5 scores were 19.5±6.4 pre-injury, 8.7±8.0 at 3 months post-injury, and 17.5±7.1 at 2 years postoperatively, with statistically significant differences ( F=123.247, P<0.001). Differences between 3 months post-injury vs. pre-injury and 2 years postoperatively vs. 3 months post-injury were statistically significant ( P<0.05). Mean PEDT scores were 5.3±3.1 pre-injury, 6.9±5.2 at 3 months post-injury, and 6.4±5.1 at 2 years postoperatively, with statistically significant differences ( F=17.014, P<0.001). The difference between 3 months post-injury and pre-injury was statistically significant ( P<0.05), but not between 2 years postoperatively and 3 months post-injury ( P>0.05). At the 2-year follow-up, 96 patients had their IIEF-5 classification restored to pre-injury levels, 85 restored PEDT classifications, and 83 restored both. Post-injury ASIA classification was positively correlated with a decrease in IIEF-5 score and an increase in PEDT score at 3 months post-injury ( P<0.05). Injury segment was positively correlated with the decrease in IIEF-5 score ( P<0.05). Time from injury to surgery showed a positive correlation with increased PEDT score at 3 months ( P<0.05). Post-injury ASIA grade, injury segment, time to surgery, age, intraoperative decompression, and spinal cord function recovery all showed significant correlations with changes in IIEF-5 and (or) PEDT scores at 2 years postoperatively ( P<0.05). According to the International Spinal Cord Injury Male Sexual Function Basic Data Set, the proportion of patients willing to discuss sexual issues increased from 29.9% at 3 months post-injury to 47.9% at 2 years postoperatively ( P<0.05). The proportion of patients with absent or diminished psychogenic erections remained stable (48.7% vs. 48.9%, P>0.05), while those with normal reflexive erections increased from 34.2% to 65.0% ( P<0.05). Conclusion:Thoracolumbar fractures with incomplete spinal cord injury result in reduced erectile function and increased incidence of premature ejaculation. The degree of spinal cord injury and the level of the injured segment are strongly correlated with the extent of sexual dysfunction. At the 2-year postoperative follow-up, 70.9% of patients had recovered sexual function to pre-injury levels.

Conclusions:In critically ill patients undergoing CRRT, the occurrence of hypotension within the first hour of CRRT initiation was not significantly associated with 90-day mortality after hospital admission. Lower serum albumin levels, higher sequential organ failure assessment scores, and the use of mechanical ventilation may be the risk factors for 90-day mortality in this population.

Objective To investigate the therapeutic effects and mechanisms of Huangqi Jianzhong Decoction(HJD)on gastric mucosal injury induced by Helicobacter pylori(Hp)infection.Methods A Wistar rat model of Hp-induced gastric mucosal injury was established.Successfully modeled rats were randomly divided into five groups:model group,low-,medium-and high-dose HJD groups,and quadruple therapy group(Omeprazole+Amoxicillin+Clarithromycin+Colloidal Bismuth pectin),8 rats per group,with an additional normal group.After 4 weeks of treatment,gastric mucosal pathological changes were assessed by hematoxylin-eosin(HE)staining.Serum levels of interleukin 1β(IL-1β),interleukin 18(IL-18),tumor necrosis factor α(TNF-α),chemokine(C-X-C motif)ligand 1(CXCL1),chemokine(C-X-C motif)ligand 9(CXCL9),and gastrin-17(G-17)were measured by enzyme-linked immunosorbent assay(ELISA).Protein expression levels of IRF8,IFN-γ,interferon-induced tetratricopeptide repeat protein 3(Ifit3)and uridine phosphorylase 1(Upp1)in gastric mucosal tissues were detected by Western Blot.Results Compared with the normal group,the model group exhibited significant gastric mucosal damage,serum levels of IL-1β,IL-18,TNF-α,CXCL1 and CXCL9 were significantly increased,G-17 was drcreased,and protein expression levels of IRF8,IFN-γ,Ifit3 and Upp1 in gastric mucosa were significantly increased,the differences being statistically significant(P＜0.05).Compared with the model group,the gastric mucosal tissue injury of rats in the medium-and high-dose of HJD groups and the quadruple therapy group was significantly improved,the levels of IL-1β,IL-18,TNF-α,CXCL1 and CXCL9 in serum were significantly decreased,G-17 was significantly increased,and the protein expression levels of IRF8,IFN-γ,Ifit3 and Upp1 in gastric mucosa were significantly decreased,the differences being statistically significant(P＜0.05).The effect in above indexes in high-does HJD groups was superior to the low-and mediun-groups.Conclusion HJD alleviates Hp-induced gastric mucosal injury by inhibiting the IRF8/IFN-γ signaling pathway and subsequent inflammatory responses.

Coronary vessels with QFR>0.80 and without interventional treatment were analyzed in this study. The primary endpoint was 3-year target vessel revascularization. Vessels with revascularization (revascularized group) during follow-up were matched 1∶1 using propensity score matching to comparable vessels without revascularization (non-revascularized group). Multivariate Cox regression analysis was used to identify the risk factors for target vessel revascularization (TVR).Results:A total of 6 212 functionally negative vessels with deferred intervention were included in the final analysis, among which 153 vessels (2.5%) underwent TVR during a 3-year follow-up. Prior to propensity score matching, 6 059 vessels comprised the non-revascularized group. At the vessel level, compared to the non-revascularized group, the revascularized group exhibited a significantly higher proportion of males (79.1% (121/153) vs. 70.2% (4 253/6 059), P=0.018), higher body mass index ((25.6±4.0) kg/m2 vs. (24.3±5.2) kg/m2, P=0.003), and a higher prevalence of hypertension (73.9% (113/153) vs. 65.1% (3 944/6 059), P=0.025). And 152 pairs of vessels were successfully matched. Multivariate Cox regression analysis identified in-stent restenosis lesions ( HR=2.59, 95% CI 1.28-5.23, P=0.008) as an independent risk factor for target vessel revascularization. Conclusions:Coronary lesions classified as functionally non-ischemic at baseline are not entirely stable and may progress to lesions that requiring revascularization over time. In-stent restenosis emerges as a critical independent predictor of revascularization.

Objective To investigate the association between neutrophil-lymphocyte ratio(NLR)and diabetic kidney disease(DKD)in patients with type 2 diabetes mellitus(T2DM).Methods 548 T2DM patients hospitalized in The Second People's Hospital of Liaocheng from January 2022 to March 2023 were divided into control(Con,UACR≤30 mg/g,n=393)group,microalbuminuria(Mic,UACR 30～300 mg/g,n=103)group and macroalbuminuria(Mac,UACR＞300 mg/g,n=52)group according to the levels of UACR.Results In the Con,Mic and Mac groups,blood urea nitrogen(BUN),serum creatinine(Scr),serum uric acid(SUA),cystatin C(CysC)and total cholesterol(TC)increased successively(P＜0.05),and estimated glomerular filtration rate(eGFR)decreased successively(P＜0.05).The systolic blood pressure(SBP),NLR,neutrophil count and lymphocyte count(Lym)in the Mic and Mac groups were higher than those in the Con group(P＜0.05).The age,DM duration and hypertension duration in the Mic group were higher than those in the Con group(P＜0.05),and the hemoglobin(Hb)in the Mac group was lower than that in the Con group(P＜0.05).Logistic regression analysis showed that Hb,Lym,age,SBP,NLR,BUN,Scr,eGFR,SUA,CysC,DM duration,hypertension,hypertension duration,and the use of antihypertensive drugs were all influencing factors for the occurrence of DKD.After adjusting for multiple confounding factors,it was shown that NLR(OR 1.223,95%CI 1.082～1.382),SBP(OR 1.018,95%CI 1.005～1.031),and eGFR(OR 0.973,95%CI 0.954～0.991)remained the influencing factors of DKD.In male DKD patients across different age groups,with BMI＜29.9 kg/m2,non-smoking,non-drinking and without comorbid diabetic retinopathy and hypertension,the NLR was significantly higher compared to the Con group(P＜0.05).However,no interaction effects were observed between these variables and NLR in relation to DKD(P＞0.05).Conclusions NLR is closely related to the occurrence and development of DKD.
