Objective:To examine the clinical features and genetic profiles of patients with thyroid peroxidase(TPO) gene mutations and provide diagnostic guidance for clinicians.Methods:A retrospective review of four patients with TPO mutations treated at Ruijin Hospital, Shanghai Jiao Tong University School of Medicine, from January 2014 to December 2023. Data on demographics, clinical manifestation, genotypes, treatment, and prognosis of these patients were analyzed.Results:Two males and two females, aged 13 to 27 years at diagnosis, presented with goiter as the initial symptom, with three cases menifesting during puberty. Laboratory findings showed mildly elevated or upper-limit-normal serum thyroid-stimulating hormone(TSH) levels, significantly increased free triiodothyronine/free thyroxine(FT 3/FT 4) ratios, and elevated thyroglobulin(TG) levels. Genetic testing revealed compound heterozygous pathogenic or likely pathogenic TPO mutations. Despite regular levothyroxine(L-T 4) therapy, goiter persisted. Three patients required thyroidectomy due to cosmetic or compressive symptoms, with pathology showing follicular hyperplasia. Conclusion:TPO mutations are characterized by adolescent-onset goiter, elevated FT 3/FT 4 ratios, and normal to high TSH. Genetic testing confirms the diagnosis. L-T 4 offers limited improvement, and surgery is often needed.

Objective:To systematically analyze the prevalence and influencing factors of psychiatric comorbidities in refractory epilepsy (RE) .Methods:The literature on the prevalence and/or influencing factors of psychiatric comorbidities in adults with RE was electronically searched in China National Knowledge Infrastructure, WanFang Data, VIP, China Biomedical Database, PubMed, Web of Science, Embase, CINAHL, OVID, UpToDate, and Cochrane Library. The search period was from the establishment of the database to July 31, 2024. Two researchers independently conducted literature screening, quality assessment and data extraction, and used RevMan 5.4 for Meta-analysis.Results:A total of 11 papers were included, with a total sample size of 1 953 cases, with a prevalence of 52.00% (cross sectional studies) and 53.00% (cohort studies) . Gender [ OR=4.76, 95% CI (3.69, 6.15) ] , epilepsy disease perception [ OR=1.10, 95% CI (1.01, 1.19) ] , seizure type [ OR=1.63, 95% CI (1.23, 2.15) ] , seizure frequency [ OR=1.54, 95% CI (1.04, 2.29) ] , epileptogenic foci location [ OR=2.72, 95% CI (1.69, 4.37) ] , disease duration [ OR=1.76, 95% CI (1.39, 2.24) ] , and medication [ OR=3.26, 95% CI (2.09, 5.08) ] were the influencing factors of psychiatric comorbidity in RE. Conclusions:The prevalence of psychiatric comorbidities in patients with RE is high, and studies of influencing factors lack specificity. Clinical monitoring of this population should be strengthened, and relevant influencing factors should be comprehensively analyzed to provide intervention targets for early preventive management and to safeguard the long-term management of patients with epilepsy.

Objective:To investigate the current status of peripherally inserted central catheter (PICC) -associated thrombosis prevention nursing practices among surgical nurses, and to provide a scientific basis for targeted future interventions.Methods:A convenience sampling method was used to select 3 151 surgical nurses from tertiary hospitals in 11 provinces and municipalities who attended the Surgical Nursing Academic Symposium of the Chinese Nursing Association between April and May 2023. The survey utilized a standardized questionnaire assessing current practices in PICC-associated thrombosis prevention among clinical nurses.Results:A total of 3 151 questionnaires were distributed, and 2 341 valid responses were collected, yielding a valid response rate of 74.29% (2 341/3 151) . Among the respondents, the training rate on PICC-associated thrombosis prevention was only 62.45% (1 462/2 341) , and just 1.28% (30/2 341) had received full-time (off-duty) training. The usage rate of standardized procedures for PICC-related thrombosis prevention was 92.40% (2 163/2 341) , and the risk assessment rate was 79.79% (1 868/2 341) . Compared to urology and cardiothoracic surgery departments, breast surgery departments had significantly higher rates of thrombosis risk assessment ( P<0.05) . Additionally, 56.69% (1 327/2 341) of surgical nurses used risk assessment tools specific to PICC-associated thrombosis. Among non-pharmacological prevention measures, the implementation rate of encouraging patients to perform grip strength exercises was only 68.26% (1 598/2 341) . Conclusions:The current level of PICC-associated thrombosis prevention nursing among surgical nurses needs further improvement. Efforts should be strengthened in professional training, implementation of standardized protocols, risk assessment, and non-pharmacological interventions.

Objective:To investigate the effect of mild moxibustion on transient receptor potential vanilloid type 1(TRPV1)channel expression in primary dysmenorrhea(PD)rats and explore its mechanism in alleviating central pain sensitization.Methods:Thirty-two female non-pregnant Wistar rats were randomized into a blank group,a model group,a mild moxibustion group,and a capsazepine group,with 8 rats in each group.Except for the blank group,the other three groups used estradiol benzoate,ice-water bath,and oxytocin to establish the rat PD model of cold-dampness stagnation pattern.The interventions began on day 1 of modeling,once a day,and lasted 10 d.The mild moxibustion group received mild moxibustion at Shenque(CV8)and Guanyuan(CV4),20 min/time;in the capsazepine group,capsazepine was injected at a dose of 2 mg/(kg·bw).The abdominal pain threshold was measured 10-30 min after oxytocin injection on day 11;enzyme-linked immunosorbent assay was used to detect serum prostaglandin F2α(PGF2α)level;the expression of TRPV1,cluster of differentiation 11B(CD11B),and proto-oncogene c-Fos in the spinal dorsal horn and hypothalamus was detected by immunofluorescence and Western blotting.Results:Compared to the blank group,the model group showed a decreased pain threshold(P<0.05)and an increased serum PGF2α level with elevated TRPV1,CD11B,and c-Fos protein expression in the spinal dorsal horn and hypothalamus(P<0.05).Compared to the model group,both the mild moxibustion group and capsazepine group showed significantly increased pain thresholds(P<0.05),along with decreased serum PGF2α levels and reduced protein expression levels of TRPV1,CD11B,and c-Fos in the spinal dorsal horn and hypothalamus(P<0.05).Rat pain threshold in the capsazepine group was higher than that in the mild moxibustion group(P<0.05).Serum PGF2α level,the expression levels of CD11B and c-Fos proteins in the spinal dorsal horn,as well as TRPV1,CD11B,and c-Fos proteins in the hypothalamus of the capsazepine group were lower than those in the mild moxibustion group(P<0.05).Conclusion:Mild moxibustion at Shenque(CV8)and Guanyuan(CV4)may alleviate the central pain sensitization in PD rats by down-regulating TRPV1 channel expression in the spinal dorsal horn and hypothalamus,thus playing an analgesic effect.

Objective To investigate the effects of indirect moxibustion on the expressions of DNA methyltransferases(DNMT)and methylation of the brain-derived neurotrophic factor(BDNF)promoter region in uterine tissues of rats with primary dysmenorrhea(PD);To explore the mechanism of epigenetic regulation of indirect moxibustion on PD model rats.Methods A total of 32 female SD rats were randomly divided into blank group,model group,indirect moxibustion group and Western medicine group,with 8 rats in each group.The PD model with cold dampness stagnation syndrome was established using ice-water baths combined with estradiol benzoate and oxytocin.Starting from the first day of modeling,the indirect moxibustion group received salt-partitioned moxibustion at"Shenque"and ginger-partitioned moxibustion at"Guanyuan"for 20 min,while the Western medicine group was gavaged ibuprofen solution.Both interventions were given once a day for 10 days.On day 11,writhing responses were observed and scored after oxytocin injection,Western blot and RT-qPCR were used to detect protein and mRNA expression of BDNF,DNMT3A and DNMT3B in uterine tissue,immunohistochemical staining was used to detect the positive expressions of DNMT3A and DNMT3B in uterine tissue.The DNA methylation of BDNF promoter region in uterine tissue was detected by sulfite sequencing.Results Compared with the blank group,the writhing latency was shortened and the writhing score increased in the model group(P<0.01);the protein and mRNA expressions of BDNF,DNMT3A and DNMT3B in uterine tissue increased(P<0.01),the positive expressions of DNMT3A and DNMT3B increased(P<0.01),and the DNA methylation rate in BDNF promoter region decreased(P<0.01).Compared with the model group,the writhing latency was lengthened and the writhing score decreased in the indirect moxibustion group and Western medicine group(P<0.05,P<0.01);the protein and mRNA expressions of BDNF,DNMT3A and DNMT3B in uterine tissue decreased(P<0.05,P<0.01),the positive expressions of DNMT3A and DNMT3B decreased(P<0.01),and the DNA methylation rate in BDNF promoter region increased(P<0.01).Conclusion Indirect moxibustion at"Shenque"and"Guanyuan"may inhibit the transcription of BDNF by increasing the DNA methylation level of BDNF promoter region,and reduce the expression of BDNF,so as to relieve the pain of PD rats.

Acute respiratory distress syndrome(ARDS)is a common clinical syndrome in intensive care unit(ICU)with high morbidity and mortality.Recently,the new global definition of ARDS has redefined the diagnosis of ARDS,which is divided into non-intubated ARDS,intubated ARDS and ARDS with limited resources.Hypoxia is the main clinical manifestation of ARDS,and respiratory support therapy is the first-line treatment for ARDS.With respect to non-intubated ARDS,current guidelines do not provide a clear preference between high flow nasal cannula(HFNC)and non-invasive mechanical ventilation(NIV).In order to improve clinical managmet of non-intubated ARDS,we review the role of HFNC and NIV in non-intubated ARDS in this paper.

Objective:To evaluate the efficacy of cyclophosphamide in patients with T-cell large granular lymphocytic leukemia (T-LGLL) and the maintenance of treatment-free remission (TFR) following drug discontinuation.Methods:Clinical data were collected from 37 patients with T-LGLL who received oral cyclophosphamide at the Regenerative Medicine Clinic of the Institute of Hematology and Blood Diseases Hospital between June 2019 and March 2024. Patient clinical characteristics, treatment efficacy, and long-term TFR were analyzed.Results:The median age of the 37 patients was 60 years (range: 37-86), and 22 (59.5%) were male. Anemia was observed in 30 patients (81.1%), and 28 (75.7%) met the diagnostic criteria for secondary pure red cell aplasia. Neutropenia occurred in 15 patients (40.5%), lymphocytosis in 11 (29.7%), and thrombocytopenia in three (8.1%). Sixteen patients (43.2%) had not received prior immunosuppressive therapy (treatment-naive group), while 21 patients (56.8%) were refractory to or had relapsed after immunosuppressive treatment (refractory/relapsed group). All patients met the treatment criteria and received oral cyclophosphamide at doses of 50-100 mg/day. Among the 36 evaluable patients, hematologic remission was achieved in 25 (69.4%), with a median time of 2.0 months (range: 0.7-7.0). There was no statistically significant difference in remission rates between the treatment-naive and refractory/relapsed groups (68.5% vs. 66.7%, P=0.589). Among the 25 patients who achieved hematologic remission, 24 discontinued cyclophosphamide. With a median follow-up of 39.0 months (range: 8.0-56.0), the median TFR duration was not reached. The estimated TFR rates were (90.87± 6.16) % at 12 months and (75.72±11.04) % at 36 months. No significant difference in TFR was observed between the treatment-naive and refractory/relapsed groups ( P=0.451) . Conclusion:Oral cyclophosphamide is effective in the treatment of T-LGLL, and patients may maintain long-term TFR following drug discontinuation.
