Objective To evaluate the protective effect of radiation protection safety education (RPSE) on patients with differentiated thyroid carcinoma (DTC) undergoing iodine-131 (¹³¹I) treatment. Methods The DTC patients who undergo ¹³¹I treatment were divided into the control group and the RPSE group using the convenience sampling method, with 142 patients in each group. Patients in the control group received routine health education, while the RPSE group received routine health education combined with RPSE. Dose equivalent rate (DER) on pillows, bed sheets, quilt covers, and household waste of patients were compared between the two groups upon discharge. Results The median (M) DERs of patients' pillows, bed sheets, quilt covers and household waste were 3.86, 3.63, 3.91 and 56.59 times higher in the control group compared with the environmental background level, respectively. The M DERs of patients' pillows, bed sheets, quilt covers were 2.23, 2.18, and 2.55 times higher in the RPSE group compared with the environmental background level, while the M DER of household waste was equivalent to the environmental background level. The DERs of patients' pillows, bed sheets, quilt covers, and household waste in the RPSE group were significantly lower than those in the control group (all P<0.001). The DERs of the above four items were lower in both male and female patients in RPSE group compared with same-gender patients in the control group (all P<0.001). The patients' DERs of the above indicators had no significant difference among different gender in both control group and RPSE group (all P>0.05), except for higher DER of household waste in female patients than that of male patients in the control group (P<0.05). There were no significant differences in the DERs of pillows, bed sheets, quilt covers, and household waste across subgroups, where patients received different treatment doses, of both the control group and the RPSE group (all P>0.05). Conclusion RPSE for DTC patients treated with ¹³¹I, reduces the DERs of pillows, bed sheets, quilt covers, and particularly household waste.

OBJECTIVE: To investigate the effects of acupuncture on the neurotransmitter levels and gut microbiota in a mouse model of Tourette syndrome (TS). METHODS: Thirty-six male C57/BL6 mice were randomly divided into 4 groups using a random number table method: 3,3'-iminodipropionitrile (IDPN) group, control group, acupuncture group, and tiapride group, with 9 mice in each group. In the IDPN group, acupuncture group, and tiapride group, mice received daily intraperitoneal injections of IDPN (300 mg/kg body weight) for 7 consecutive days to induce stereotyped behaviors. Subsequently, in the acupuncture intervention group, standardized acupuncture treatment was administered for 14 consecutive days to IDPN-induced TS model mice. The selected acupoints included Baihui (DU 20), Yintang (DU 29), Waiguan (SJ 5), and Zulinqi (GB 41). In the tiapride group, mice were administered tiapride (50 mg/kg body weight) via oral gavage daily for 14 consecutive days. The control group, IDPN group, and acupuncture group received the same volume of saline orally for 14 consecutive days. Stereotypic behaviors were quantified through behavioral assessments. Neurotransmitter levels, including dopamine (DA), glutamate (Glu), and aspartate (ASP) in striatal tissue were measured using enzyme-linked immunosorbent assay. Dopamine transporter (DAT) expression levels were additionally quantified through quantitative polymerase chain reaction (qPCR). Gut microbial composition was analyzed through 16S ribosomal RNA gene sequencing, while metabolic profiling was conducted using liquid chromatography-mass spectrometry (LC-MS). RESULTS: Acupuncture administration significantly attenuated stereotypic behaviors, concurrently reducing striatal levels of DA, Glu and ASP concentrations while upregulating DAT expression compared with untreated TS controls (P<0.05 or P<0.01). Comparative analysis identified significant differences in Muribaculaceae (P=0.001), Oscillospiraceae (P=0.049), Desulfovibrionaceae (P=0.001), and Marinifilaceae (P=0.014) following acupuncture intervention. Metabolomic profiling revealed alterations in 7 metabolites and 18 metabolic pathways when compared to the TS mice, which involved various amino acid metabolisms associated with DA, Glu, and ASP. CONCLUSIONS Acupuncture demonstrates significant modulatory effects on both central neurotransmitter systems and gut microbial ecology, thereby highlighting its dual therapeutic potential for TS management through gut-brain axis regulation.

OBJECTIVE: This study aimed to explore the association between body mass index (BMI) and mortality based on the 10-year population-based multicenter prospective study. METHODS: A general population-based multicenter prospective study was conducted at four sites in rural China between 2013 and 2023. Multivariate Cox proportional hazards models and restricted cubic spline analyses were used to assess the association between BMI and mortality. Stratified analyses were performed based on the individual characteristics of the participants. RESULTS: Overall, 19,107 participants with a sum of 163,095 person-years were included and 1,910 participants died. The underweight (< 18.5 kg/m ²) presented an increase in all-cause mortality (adjusted hazards ratio [ aHR] = 2.00, 95% confidence interval [ CI]: 1.66-2.41), while overweight (≥ 24.0 to < 28.0 kg/m ²) and obesity (≥ 28.0 kg/m ²) presented a decrease with an aHR of 0.61 (95% CI: 0.52-0.73) and 0.51 (95% CI: 0.37-0.70), respectively. Overweight ( aHR = 0.76, 95% CI: 0.67-0.86) and mild obesity ( aHR = 0.72, 95% CI: 0.59-0.87) had a positive impact on mortality in people older than 60 years. All-cause mortality decreased rapidly until reaching a BMI of 25.7 kg/m ² ( aHR = 0.95, 95% CI: 0.92-0.98) and increased slightly above that value, indicating a U-shaped association. The beneficial impact of being overweight on mortality was robust in most subgroups and sensitivity analyses. CONCLUSION This study provides additional evidence that overweight and mild obesity may be inversely related to the risk of death in individuals older than 60 years. Therefore, it is essential to consider age differences when formulating health and weight management strategies.

ObjectiveTo explore the protective effects of Dahuang Tangluo pills on early diabetic kidkdey disease （DKD） in db/db mice. MethodEight db/m mice were selected as the control group. Forty male db/db mice were selected and blood samples were collected via tail vein to measure fasting blood glucose （FBG）. Mice with FBG ≥ 16.7 mmol·L^-1， increased urine output， and persistent albuminuria were considered successful in model establishment. After successful modeling， they were randomly divided into a model group， a dapagliflozin group （1.5 mg·kg^-1·d^-1）， and high， medium， and low dose groups of Dahuang Tangluo pills （3.6， 1.8， 0.9 g·kg^-1·d^-1， respectively）， with eight mice in each group. All medication groups were administered orally， while the control and model groups were given an equal amount of distilled water by gavage daily. After continuous administration for 10 weeks， the survival status of the mice was observed， and their body weight， FBG， and kidney function-related indicators were measured. Inflammatory indicators in renal tissues were determined by enzyme-linked immunosorbent assay （ELISA）. Hematoxylin-eosin （HE） staining， Masson staining， and electron microscopy were used to observe the pathological changes in renal tissues in each group. Immunofluorescence was employed to examine the expression of advanced glycation end products （AGEs） and receptors for advanced glycation end products （RAGE） proteins. Real-time quantitative polymerase chain reaction （Real-time PCR） and Western blot were utilized to detect the gene and protein expression levels of AGEs， RAGE， inhibitor of nuclear factor-κB （NF-κB） kinase （IKK）， and NF-κB in the renal tissues of mice in each group. ResultCompared with control group， the model group showed a significant increase in body weight， FBG， serum creatinine （SCr）， urinary microalbumin/urine creatinine ratio （ACR）， total cholesterol （TC）， and triglycerides （TG） （P<0.05）. The levels of intercellular adhesion molecule-1 （ICAM-1）， interleukin-6 （IL-6）， and tumor necrosis factor-alpha （TNF-α） in renal tissues were significantly elevated （P<0.05）. Renal histopathological staining and electron microscopy revealed loose arrangement， gaps， structural disarray， mesangial proliferation， and significant fibrosis in renal tissues. Real-time PCR results showed a significant increase in the expression of RAGE， IKK， and NF-κB genes in renal tissues （P<0.05）. Immunofluorescence results demonstrated a significant increase in the expression of AGEs and RAGE proteins in renal tissues （P<0.05）. Western blot results showed a significant increase in the expression of AGEs， RAGE， IKK， and NF-κB proteins in renal tissues （P<0.05）. After drug intervention， compared with model group， the dapagliflozin group and the high-dose Dahuang Tangluo pills group showed significant reductions in body weight， FBG， SCr， and ACR （P<0.05）， and a significant decrease in TC in mouse serum （P<0.05）， while the high-dose Dahuang Tangluo pills group showed a significant decrease in TG in mouse serum （P<0.05）. All treatment groups showed a significant reduction in ICAM-1， IL-6， and TNF-α in renal tissues （P<0.05）. Renal histopathological staining and electron microscopy showed improved kidney injury， decreased collagen fiber deposition， and reduced mesangial proliferation in all treatment groups. Real-time PCR results showed a significant decrease in the expression of RAGE， IKK， and NF-κB genes in the dapagliflozin group and the high- and medium-dose Dahuang Tangluo pills groups （P<0.05）. Immunofluorescence results demonstrated a significant decrease in the expression of AGEs and RAGE proteins in the dapagliflozin group and the high- and medium-dose Dahuang Tangluo pills groups （P<0.05）. Western blot results showed a significant decrease in the expression of AGEs， RAGE， IKK， and NF-κB proteins in the dapagliflozin group and the high- and medium-dose Dahuang Tangluo pills groups （P<0.05）. ConclusionDahuang Tangluo pills can improve the pathological structure of the kidneys and reduce renal inflammation in DKD mice， possibly through inhibiting the AGEs/RAGE/IKK/NF-κB pathway.

Purpose::Vibrio vulnificus ( V. Vulnificus) infection is characterized by rapid onset, aggressive progression, and challenging treatment. Bacterial resistance poses a significant challenge for clinical anti-infection treatment and is thus the subject of research. Enhancing host infection tolerance represents a novel infection prevention strategy to improve patient survival. Our team initially identified cytochrome P4501A1 (CYP1A1) as an important target owing to its negative modulation of the body's infection tolerance. This study explored the superior effects of the CYP1A1 inhibitor bergamottin compared to antibiotic combination therapy on the survival of mice infected with multidrug-resistant V. Vulnificus and the protection of their vital organs. Methods::An increasing concentration gradient method was used to induce multidrug-resistant V. Vulnificus development. We established a lethal infection model in C57BL/6J male mice and evaluated the effect of bergamottin on mouse survival. A mild infection model was established in C57BL/6J male mice, and the serum levels of creatinine, urea nitrogen, aspartate aminotransferase, and alanine aminotransferase were determined using enzyme-linked immunosorbent assay to evaluate the effect of bergamottin on liver and kidney function. The morphological changes induced in the presence of bergamottin in mouse organs were evaluated by hematoxylin and eosin staining of liver and kidney tissues. The bacterial growth curve and organ load determination were used to evaluate whether bergamottin has a direct antibacterial effect on multidrug-resistant V. Vulnificus. Quantification of inflammatory factors in serum by enzyme-linked immunosorbent assay and the expression levels of inflammatory factors in liver and kidney tissues by real-time quantitative polymerase chain reaction were performed to evaluate the effect of bergamottin on inflammatory factor levels. Western blot analysis of IκBα, phosphorylated IκBα, p65, and phosphorylated p65 protein expression in liver and kidney tissues and in human hepatocellular carcinomas-2 and human kidney-2 cell lines was used to evaluate the effect of bergamottin on the nuclear factor kappa-B signaling pathway. One-way ANOVA and Kaplan-Meier analysis were used for statistical analysis. Results::In mice infected with multidrug-resistant V. Vulnificus, bergamottin prolonged survival ( p = 0.014), reduced the serum creatinine ( p = 0.002), urea nitrogen ( p = 0.030), aspartate aminotransferase ( p = 0.029), and alanine aminotransferase ( p = 0.003) levels, and protected the cellular morphology of liver and kidney tissues. Bergamottin inhibited interleukin (IL)-1β, IL-6, and tumor necrosis factor (TNF)-α expression in serum (IL-1β: p = 0.010, IL-6: p = 0.029, TNF-α: p = 0.025) and inhibited the protein expression of the inflammatory factors IL-1β, IL-6, TNF-α in liver (IL-1β: p = 0.010, IL-6: p = 0.011, TNF-α: p = 0.037) and kidney (IL-1β: p = 0.016, IL-6: p = 0.011, TNF-α: p = 0.008) tissues. Bergamottin did not affect the proliferation of multidrug-resistant V. Vulnificus or the bacterial load in the mouse peritoneal lavage fluid ( p = 0.225), liver ( p = 0.186), or kidney ( p = 0.637). Conclusion::Bergamottin enhances the tolerance of mice to multidrug-resistant V. Vulnificus infection. This study can serve as a reference and guide the development of novel clinical treatment strategies for V. Vulnificus.

Objective To evaluate the effect of electroacupuncture at Chize and Shangjuxu on the prognosis and respiratory dynamics in patients with acute respiratory distress syndrome(ARDS).Methods A prospective randomized controlled study was conducted to collect patients with ARDS admitted to the Department of Emergency Medicine of Tongde Hospital of Zhejiang Province from December 2020 to September 2022.A total of 142 patients with ARDS from the Department of Emergency Medicine of Tongde Hospital of Zhejiang Province were selected for this study.Seven patients were excluded due to rapid deterioration,3 patients withdrew the informed consent,and finally 132 patients were enrolled.According to the order of enrollment,they were randomly divided into the electroacupuncture group and the conventional treatment group based on the random number table.The conventional treatment group received conventional treatment for ARDS,while the electroacupuncture group combined with electroacupuncture at Chize and Shangjuxu,the treatment lasted for 30 minutes.The mortality at day 60 and secondary efficacy indicators such as hospital stay,ventilator-free days at 28 day,and mechanical ventilation time of two groups were compared,and the indicators of respiratory mechanics and oxygenation such as inhalation oxygen concentration(FiO2),tidal volume(VT),positive end-expiratory pressure(PEEP),plateau pressure(Pplat),lung static compliance(Cst),oxygenation index(PaO2/FiO2)were also compared.Then the Kaplan-Meier survival curves were drawn to compare the differences in cumulative survival rates within 60 days between the two groups.Results The mortality at day 60 in the electroacupuncture group was lower than that in the conventional treatment group[33.33％(22/66)vs.40.91％(27/66)],but the difference was not statistically significant(P>0.05),and the hospital stay in the electroacupuncture group was significantly shorter than that in the conventional treatment group(days:25.09±11.57 vs.30.21±15.94,P<0.05).The ventilator-free days at 28 days in the electroacupuncture group were significantly higher than those in the conventional treatment group(days:10.06±7.35 vs.7.67±5.72,P<0.05).There was no statistically significant difference in mechanical ventilation time between the two groups(days:15.70±9.05 vs.18.39±9.55,P>0.05).After 72 hours of treatment,the FiO2,VT,and PaCO2 levels in the electroacupuncture group were significantly lower than those in the conventional treatment group[FiO2:0.39±0.07 vs.0.44±0.09,VT(mL/kg):6.27±0.74 vs.6.62±0.74,PaCO2(mmHg,1 mmHg≈0.133 kPa):39.94±4.52 vs.41.95±4.19,all P<0.05].Conclusion Electroacupuncture at Chize and Shangjuxu can effectively shorten the course of ARDS and improve prognosis,which may be related to the improvement of respiratory dynamics by electroacupuncture treatment.

ABO incompatible(ABO-I) liver grafts will affect the prognosis of liver transplantation. With the improvement of perioperative treatment,including plasma exchange,rituximab,splenectomy,etc.,the prognosis of ABO-I liver transplantation has been greatly improved. Because children's immune systems are not fully developed,the perioperative management of ABO-I pediatric liver transplantation is significantly different from that of adults. Reducing the perioperative anti-donor ABO antibody titer is the key to the perioperative management of ABO-I liver transplantation. This article summarizes literatures on the perioperative management of ABO-I pediatric liver transplantation, including the perioperative anti-rejection regimen in pediatric recipients of different ages, splenectomy, postoperative monitoring and postoperative complications, etc.

Management and treatment of terminal metastatic castration-resistant prostate cancer (mCRPC) remains heavily debated. We sought to investigate the efficacy of programmed cell death 1 (PD-1) inhibitor plus anlotinib as a potential solution for terminal mCRPC and further evaluate the association of genomic characteristics with efficacy outcomes. We conducted a retrospective real-world study of 25 mCRPC patients who received PD-1 inhibitor plus anlotinib after the progression to standard treatments. The clinical information was extracted from the electronic medical records and 22 patients had targeted circulating tumor DNA (ctDNA) next-generation sequencing. Statistical analysis showed that 6 (24.0%) patients experienced prostate-specific antigen (PSA) response and 11 (44.0%) patients experienced PSA reduction. The relationship between ctDNA findings and outcomes was also analyzed. DNA-damage repair (DDR) pathways and homologous recombination repair (HRR) pathway defects indicated a comparatively longer PSA-progression-free survival (PSA-PFS; 2.5 months vs 1.2 months, P = 0.027; 3.3 months vs 1.2 months, P = 0.017; respectively). This study introduces the PD-1 inhibitor plus anlotinib as a late-line therapeutic strategy for terminal mCRPC. PD-1 inhibitor plus anlotinib may be a new treatment choice for terminal mCRPC patients with DDR or HRR pathway defects and requires further investigation.
