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.

ObjectiveMagnetoencephalography (MEG), a non-invasive neuroimaging technique, meticulously captures the magnetic fields emanating from brain electrical activity. Compared with MEG based on superconducting quantum interference devices (SQUID), MEG based on optically pump magnetometer (OPM) has the advantages of higher sensitivity, better spatial resolution and lower cost. However, most of the current studies are clinical studies, and there is a lack of animal studies on MEG based on OPM technology. Pain, a multifaceted sensory and emotional phenomenon, induces intricate alterations in brain activity, exhibiting notable sex differences. Despite clinical revelations of pain-related neuronal activity through MEG, specific properties remain elusive, and comprehensive laboratory studies on pain-associated brain activity alterations are lacking. The aim of this study was to investigate the effects of inflammatory pain (induced by Complete Freund’s Adjuvant (CFA)) on brain activity in a rat model using the MEG technique, to analysis changes in brain activity during pain perception, and to explore sex differences in pain-related MEG signaling. MethodsThis study utilized adult male and female Sprague-Dawley rats. Inflammatory pain was induced via intraplantar injection of CFA (100 μl, 50% in saline) in the left hind paw, with control groups receiving saline. Pain behavior was assessed using von Frey filaments at baseline and 1 h post-injection. For MEG recording, anesthetized rats had an OPM positioned on their head within a magnetic shield, undergoing two 15-minute sessions: a 5-minute baseline followed by a 10-minute mechanical stimulation phase. Data analysis included artifact removal and time-frequency analysis of spontaneous brain activity using accumulated spectrograms, generating spectrograms focused on the 4-30 Hz frequency range. ResultsMEG recordings in anesthetized rats during resting states and hind paw mechanical stimulation were compared, before and after saline/CFA injections. Mechanical stimulation elevated alpha activity in both male and female rats pre- and post-saline/CFA injections. Saline/CFA injections augmented average power in both sexes compared to pre-injection states. Remarkably, female rats exhibited higher average spectral power 1 h after CFA injection than after saline injection during resting states. Furthermore, despite comparable pain thresholds measured by classical pain behavioral tests post-CFA treatment, female rats displayed higher average power than males in the resting state after CFA injection. ConclusionThese results imply an enhanced perception of inflammatory pain in female rats compared to their male counterparts. Our study exhibits sex differences in alpha activities following CFA injection, highlighting heightened brain alpha activity in female rats during acute inflammatory pain in the resting state. Our study provides a method for OPM-based MEG recordings to be used to study brain activity in anaesthetized animals. In addition, the findings of this study contribute to a deeper understanding of pain-related neural activity and pain sex differences.

Objective To investigate the mechanism of modified Guizhi Fuling Pills in treating diabetic kidney disease(DKD)through autophagy regulation based on network pharmacology and experimental validation.Methods Active components and action targets of modified Guizhi Fuling Pills were screened via the TCMSP database.DKD-related autophagy targets were obtained from GeneCards,TTD,DrugBank and PharmGKB.A protein-protein interaction network was constructed using STRING,followed by GO functional and KEGG pathway enrichment analyses via DAVID.Molecular docking of key components and core targets was performed using AutoDock Tools 1.5.7.DKD model rats were prepared.The rats were randomly divided into normal group,model group,valsartan group(50 mg/kg),and modified Guizhi Fuling Pills low-,medium-and high-dosage group(9.9,19.8 and 39.6 g/kg).After 8-week interventions,body mass and water intake were recorded;fasting blood glucose,24 h urinary total protein(24 hUTP),urinary albumin-to-creatinine ratio(UACR)were monitored.Renal histopathology was evaluated via HE and Masson staining.Western blot was used to detect protein expressions of AMPK/FOXO1 pathway(p-AMPK,AMPK,FOXO1)and autophagy markers(Beclin-1,p62),while quantitative real-time PCR was used to assess AMPK and FOXO1 mRNA expressions.Results A total of 146 active components of Guizhi Fuling Pills and 33 main targets for treating DKD were screened,with the core targets including FOXO1,BCL2,TP53 and PTEN.KEGG pathway enrichment analysis suggested that AMPK/FOXO1 signaling pathway,AGE-RAGE and insulin signaling pathways may play a core regulatory role.Guizhi Fuling Pills could significantly reduce the body mass of DKD rats,reduce water intake,decrease renal index,decrease fasting blood glucose,24 hUTP and UACR(P<0.05,P<0.01),improve renal tissue pathology,increase AMPK,FOXO1,Beclin-1 protein expressions and AMPK,FOXO1 mRNA expressions(P<0.05),and reduce p62 protein expression(P<0.05).Conclusion Modified Guizhi Fuling Pills may exert therapeutic effects on DKD by regulating the AMPK-FOXO1-autophagy axis.

Objective:To evaluate the design methodology and efficacy of skin excision in sitting and supine positions of blepharoplasty.Methods:A retrospective study was performed on 31 female patients who received double eyelid surgery at the Department of Plastic and Aesthetic Surgery, Affiliated Hospital of Qingdao University, from January to June 2021. The patients ′ ages varied from 18 to 37 years, with a mean age of (26.5±5.2) years. Of the patients, 27 exhibited single eyelids, while 4 presented with shallow double eyelids. All patients demonstrated laxity of the upper eyelid skin. The method of utilizing the sitting and supine positions was employed to determine the extent of skin excision, subsequently leading to full-incision double eyelid surgery. Follow-up was performed through clinic visits and WeChat to monitor double eyelid morphology, complications, and evaluate patient satisfaction. Results:All 31 patients successfully underwent the surgical procedure. Postoperative follow-up duration varied from 3 to 12 months. The double eyelid lines manifested as natural and seamless, with suitable width. All patients exhibited satisfactory eyelid closure, with no instances of ectropion or incomplete eyelid closure. Skin laxity of the upper eyelid was significantly ameliorated in all instances. The patient satisfaction rate was 100% (31/31).Conclusions:The sitting and supine position for executing skin excision in double eyelid surgery is straight forward to implement. Postoperative outcomes demonstrate natural and seamless double eyelid contours, with adequate rectification of upper eyelid skin laxity.

PURPOSE: This study aims to identify the prevalence and risk factors of military training-related abdominal injuries and help plan and conduct training properly. METHODS: This questionnaire survey study was conducted from October 2021 to May 2022 among military personnel from 6 military units and 8 military medical centers and participants' medical records were consulted to identify the training-related abdominal injuries. All the military personnel who ever participated in military training were included. Those who refused to participate in this study or provided an incomplete questionnaire were excluded. The questionnaire collected demographic information, type of abdominal injury, frequency, training subjects, triggers, treatment, and training disturbance. Chi-square test and t-test were used to compare baseline information. Univariate and multivariate regression analyses were used to explore the risk factors associated with military training-related abdominal injuries. RESULTS: A total of 3058 participants were involved in this study, among which 1797 (58.8%) had suffered training-related abdominal injuries (the mean age was 24.3 years and the service time was 5.6 years), while 1261 (41.2%) had no training-related abdominal injuries (the mean age was 23.1 years and the service time was 4.3 years). There were 546 injured patients (30.4%) suspended the training and 84 (4.6%) needed to be referred to higher-level hospitals. The most common triggers included inadequate warm-up, fatigue, and intense training. The training subjects with the most abdominal injuries were long-distance running (589, 32.8%). Civil servants had the highest rate of abdominal trauma (17.1%). Age ≥ 25 years, military service ≥ 3 years, poor sleep status, and previous abdominal history were independent risk factors for training-related abdominal injury. CONCLUSION More than half of the military personnel have suffered military training-related abdominal injuries. Inadequate warm-up, fatigue, and high training intensity are the most common inducing factors. Scientific and proper training should be conducted according to the factors causing abdominal injuries.
