Objective:To investigate the long-term efficacy and influencing factors of transcatheter adrenal ablation in patients with primary aldosteronism (PA).Methods:This cohort study retrospectively enrolled PA patients who underwent transcatheter adrenal ablation at Daping Hospital, Army Medical University between January 2021 and December 2024. According to PASO criteria, patients were categorized into groups based on clinical outcomes (complete, partial, or no remission), biochemical outcomes (complete, partial, or no remission), and composite outcomes (complete or incomplete remission). All participants underwent 1-year follow-up, with intergroup comparisons of clinical characteristics and surgical approaches. Multivariate logistic regression models were used to identify factors influencing long-term efficacy post-transcatheter adrenal ablation in PA patients.Results:A total of 122 PA patients were enrolled, aged (47.7±11.1) years, including 55 males (45.1%). Baseline aldosterone-to-renin ratio was 0.43(0.19,0.86)(pmol·L -1)/(μU·L -1). Bilateral adrenal lesions were present in 33 cases (27.1%), while 70 (57.4%) had nodules or adenomas. Adrenal venous sampling confirmed lateralized hypersecretion in 107 patients (87.7%, left or right dominance). According to PASO criteria, 93.4% (114/122) and 95.1% (116/122) of patients achieved complete or partial remission in biochemical and clinical parameters at 1-year post-ablation, respectively. For biochemical outcomes: 40 complete, 74 partial, and 8 no remission. Patients in the partial-remission group were older than those in the no-remission group ((49.4±11.2) vs. (39.6±9.8) years), while complete-remission group had higher bilateral non-lateralized secretion rates than partial remission group (27.5% vs. 4.1%, both P<0.05). For clinical outcomes: 26 complete, 90 partial, 6 no remission. Compared to complete-remission group, partial-remission group had higher male proportion (51.1% vs. 26.9%), longer hypertension duration (4.0 (0.7, 10.0) years vs. 1.5 (0.1, 5.0) years), but lower office diastolic blood pressure ((88±11) mmHg vs. (94±12 mmHg), 1 mmHg=0.133 kPa, all P<0.05). For composite outcomes: 56 complete and 66 incomplete remission. Compared with incomplete remission group, complete remission group had lower prevalence of diabetes (8.9% vs. 22.7%) and higher proportion of bilateral non-lateralized secretion (21.4% vs. 4.6%, both P<0.05). Multivariate logistic regression identified diabetes ( OR=3.635, 95% CI 1.029-12.834, P=0.045) and lateralized secretion ( OR=9.056, 95% CI 2.039-40.212, P=0.004) as independent risk factors for poor composite outcomes after transcatheter adrenal ablation in PA patients, whereas higher office diastolic blood pressure acts as a protective factor ( OR=0.957, 95% CI 0.925-0.992, P=0.015). Conclusion:One year after transcatheter adrenal ablation, the majority of patients achieved complete or partial remission in biochemical and clinical parameters.Patients with non-lateralized adrenal hypersecretion demonstrated a higher likelihood of sustained biochemical remission and superior composite outcomes compared to those with lateralized hypersecretion.

Objective To explore the application value of adaptive window width and level algorithm in 3D vascular reconstruction from head and neck CT angiography for achieving consistent reconstruction results at different contrast agent dosages.Methods Both direct vascular reconstruction and reconstruction after applying adaptive window width and level algorithm were conducted in 100 cases undergoing head and neck CT angiography;and the reconstruction results were compared.Results In the cases with excessive or insufficient contrast agent,the overall effect of reconstructions using adaptive window width and level algorithm was superior to that of direct reconstruction,particularly in displaying intracranial small vessels and plaques.Conclusion The adaptive window width and level algorithm has high application potential in vascular reconstruction from head and neck CT angiography,and demonstrates superior generalization in highlighting plaques,adapting to different contrast agent dosages,and displaying intracranial small vessels.

Objective:The SF-36 Scale was utilized to compare the differences in the dimensions of survival quality between subway microwave contact personnel and administrative personnel to provide a scientific basis for improving the quality of life of microwave contact personnel.Methods:In October 2023, 264 occupational personnel exposed to microwaves were selected as the microwave exposure group, and 104 administrative personnel not exposed to microwaves in a railroad enterprise were selected as the administrative control group. The self-administered basic data questionnaire and SF-36 Scale were applied to investigate the basic conditions, daily behaviors and survival quality of the research objects. And the microwave exposure doses of each post were measured. The differences in basic conditions, daily behaviors and survival quality of the microwave exposure group and the administrative control group were analyzed. And logistic regression was used to analyze the influencing factors of survival quality in the microwave exposure group.Results:There were significant differences in gender, age, marital status, smoking status and sleep status between the microwave exposure group and the administrative control group ( P<0.05) . The microwave exposure group had lower scores than the administrative control group in the six dimensions of role physical, body pain, general health, vitality, social function, mental health and SF-36 average total score, and had higher score in reported health transition ( P<0.05) . The logistic regression analysis showed that the probability of low total SF-36 score in microwave exposure group with bachelor's degree or above was 0.46 times that of junior college degree (95% CI: 0.24-0.90, P=0.023) . The probability of low total SF-36 score in microwave exposure group with exercised 4 or more times per week was 4.27 times that of those who never or occasionally exercised (95% CI: 1.41-13.00, P=0.010) . The probabilities of low total SF-36 score in microwave exposure group with sleep light and dream, wake up in the middle night and hard to fall asleep were 11.04 and 7.38 times higher than those without sleep disturbance (95% CI: 3.35-36.32, P<0.001; 95% CI: 1.42-38.50, P=0.018) . The probability of low total SF-36 score in microwave exposure group with daily dose of 1.74 μW·h/cm 2 was 1.75 times that of the daily dose of 1.02 μW·h/cm 2 (95% CI: 1.08-3.82, P=0.008) . Conclusion:The education level, physical exercise, sleep status and microwave exposure dose are important factors affecting the survival quality of microwave exposed personnel. Occupational health education and behavioral life intervention should be strengthened to improve their survival quality.

Objective To observe the correlations of pontine biological indicators on fetal brain median sagittal MRI with gestational week.Methods Data of head MRI of 226 normal fetuses without obvious abnormalities of central nervous system(normal group)and 17 fetuses with abnormalities(abnormal group)at gestational age of 23 to 38 weeks were retrospectively analyzed.Pontine biological indicators based on median sagittal MRI were obtained,including pons anteroposterior diameter(PAD),total pons area(TPA),pontine basal anteroposterior length(AP),pontine basal cranio-caudal length(CC),basis pontis area(BPA)and pontine angle of midbrain(MAP).According to the gestational week,the fetuses of normal group were divided into 8 subgroups.The distributing ranges of pontine biological indicators at different gestational weeks were analyzed,and the correlations of pontine biological indicators with gestational week in normal group were explored,and the developmental status of fetal pons in abnormal group were assessed.Results In normal group,PAD,TPA,AP,CC and BPA all showed linear positive correlation(r=0.887,0.914,0.787,0.866,0.865,all P＜0.001),while MAP was not significantly correlated with gestational week(P＞0.05).Among 17 fetuses in abnormal group,abnormal PAD or TPA was found each in 8 fetuses,abnormal AP was observed in 14,abnormal CC was noticed in 3 and abnormal BPA was found in 11 fetuses.Conclusion Fetal pontine biological indicators such as PAD,TPA,AP,CC and BPA on median sagittal MRI were positively correlated with gestational week,hence being able to be used for evaluating fetal pontine development.

BACKGROUND:In recent years,with the improvement of living standards,non-alcoholic fatty liver disease has a gradually increasing trend.miRNA-122 is one of the most abundant microRNAs in the liver,which plays an important role in maintaining the environmental stability and differentiation of the liver.Exercise training is a non-drug treatment for non-alcoholic fatty liver disease,which may improve liver lipid metabolism by regulating the expression of miRNA-122. OBJECTIVE:To review the effects of miRNA-122 on the pathological factors related to non-alcoholic fatty liver disease as well as the effects of exercise on the expression of miRNA-122 and the occurrence and development of nonalcoholic fatty liver disease. METHODS:The first author searched the databases of CNKI,WanFang,VIP,PubMed,Geenmedical,EBSCO,Medline,Web of Science,and Elsevier using"non-alcoholic fatty liver disease,microRNA,microRNA-122,lipid metabolism,inflammatory response,insulin resistance,exercise,physical exercise,exercise training"as the English and Chinese search terms for all relevant literature published before June 5,2022.All included documents were screened,summarized,and analyzed.Finally,68 documents were included for review. RESULTS AND CONCLUSION:Compared with the healthy control group,the expression of circulating miRNA-122 is increased in patients with non-alcoholic fatty liver disease.The level of miRNA-122 may show different expression levels at different stages of non-alcoholic fatty liver disease.miRNA-122 can regulate the expression of downstream-related proteins,influence lipid metabolism,inflammatory response,insulin resistance and other pathogenic factors in non-alcoholic fatty liver disease by targeting base complementary pairing sites on mRNA or directly acting as physiological ligands of some RNA receptors.Different exercise modes can improve non-alcoholic fatty liver disease.Therefore,patients with non-alcoholic fatty liver disease need to complete at least 120 minutes of moderate-intensity exercise every week to have a positive effect.For patients who can tolerate various exercises,priority should be given to the combination of aerobic and resistance exercises 4-5 times a week.The exercise intensity should be 50%-70%of the maximum heart rate and the exercise should last for>3 months.For patients with poor tolerance,resistance exercise may be more feasible than aerobic exercise.In addition,patients with non-alcoholic fatty liver disease can also choose proper exercise modes according to their own disease conditions(such as liver enzymes and lipid levels).Exercise can be used as a feasible strategy to prevent non-alcoholic fatty liver disease,reduce liver steatosis,and alleviate liver inflammatory response and insulin resistance.Exercise training can regulate the expression of miRNA-122,but in patients with non-alcoholic fatty liver disease,the effect of exercise on miRNA-122 and its related signal pathways remains to be studied.

Objective:To explore the effect of tumor plastic surgery in breast conserving surgery for early breast cancer.Methods:From March 2015 to March 2021, 80 female patients with breast cancer, aged 31 to 55 (43±12) years, who were admitted to the Department of Breast and Thyroid Surgery, the First People′s Hospital of Chenzhou City, Hunan Province, were divided into plastic breast conserving group and conventional breast conserving group, with 40 cases in each group. The plastic surgery breast conserving group used plastic surgery techniques to repair local breast defects after surgery, while the conventional breast conserving group used fascial fat flaps around the cutting edge to repair local defects; the differences in surgical related indicators and postoperative complications were compared between two groups of patients, and the postoperative cosmetic effect was evaluated.Results:Both groups successfully completed the conservative surgery. The operation time, blood loss, and drainage tube retention time in the oncoplastic conservative surgery group were longer than those in the conventional conservative surgery group, and the differences were statistically significant (all P<0.001). The 2nd cut margin expansion rate was 2.5% (1/40) in the oncoplastic conservative surgery group, which was lower than that in the conventional conservative surgery group (20%, 8/40), and the difference was statistically significant ( P=0.034). There were 3 cases of partial necrosis and 2 cases of subcutaneous fat embolism in the oncoplastic conservative surgery group after surgery, and 1 case of partial necrosis and 1 case of subcutaneous fat embolism in the conventional conservative surgery group. All of them healed after drainage and dressing changes. The postoperative aesthetic effect evaluation showed that the excellent rate in the oncoplastic conservative surgery group was 95% (38/40), and the excellent rate in the conventional conservative surgery group was 70% (28/40). The difference was statistically significant ( P=0.003). After a follow-up of 36 to 96 months, no local recurrence or distant metastasis was found in either group. Conclusions:Breast-conserving surgery can enable early breast cancer patients to achieve wider tumor margins and better aesthetic effects, with good safety and is worth clinical application.

Objective:To summarize the clinical characteristics of 4 cases of mixed pituitary adenomas involving growth hormone(GH), prolactin(PRL), and thyroid stimulating hormone(TSH), and explore the standardized management approaches.Methods:The clinical data of four GH/PRL/TSH mixed pituitary adenoma patients diagnosed by Peking Union Medical College Hospital were retrospectively analyzed, including clinical manifestations, biochemical parameters, radiographic characteristics, as well as treatment and prognosis. Then literature review was conducted.Results:Among the 4 patients, 3 were male, with onset ages ranging from 15 to 38 years. All patients presented with coarse facial features as initial symptom. Three patients had visual impairment or visual field defects. All 4 patients had significantly elevated levels of GH and insulin-like growth factor-Ⅰ(IGF-Ⅰ). GH was not inhibited by oral glucose tolerance test. PRL concentration was over 100 ng/mL. Triiodothyronine(T 3)and thyroxine(T 4)were also elevated, while TSH was not inhibited. All pituitary adenomas in four cases were macroadenomas or giant adenomas, all of which were invasive growth, and one case developed pituitary stroke. Except for one patient who did not receive treatment in our hospital due to medical expenses, the remaining three patients underwent a combined treatment of medication and transnasal transsphenoidal pituitary adenoma resection. Among them, one patient had relief of central hyperthyroidism and hyperprolactinemia, but GH/IGF-Ⅰ did not meet the remission criteria. The other two patients had persistent non-resolution of at least 2 hormone axes. Conclusions:Patients with GH/PRL/TSH mixed pituitary adenoma were mainly characterized by coarse facial features, GH/PRL/TSH hyperfunction, large adenoma volume, low biochemical remission after surgery combined with drug treatment, and poor clinical prognosis.
