Objective:To observe the high-frequency ultrasound characteristics of the median nerve（MN）in patients with acromegaly，and to investigate the clinical value of multiparameter quantitative ultrasound for noninvasive assessment of carpal tunnel syndrome（CTS）in acromegalic patients.Methods:A total of 132 acromegalic patients due to pituitary growth hormone tumors in Huashan Hospital during July 2023 to September 2024 including initial patients and postoperative revisions were prospectivly collected. The patients were divided into no neurological symptoms group（ n=51）and clinical CTS group（ n=81）based on the Boston Carpal Tunnel Questionnaire. All patients underwent bilateral MN ultrasonography，the ultrasound parameters included the cross-sectional area（CSA）of MN at the entrance of carpal tunnel，the maximum CSA of MN in carpal tunnel，the maximum and minimum thickness of MN in carpal tunnel，CSA of MN at forearm 1/3，soft tissue thickness at the wrist，CSA of MN at elbow transverse stripe，blood flow signals within the MN at the carpal tunnel，ratio of the CSA（CSA of MN at the entrance of carpal tunnel/ CSA of MN at forearm 1/3），ratio of thickness（maximum / minimum thickness of MN in carpal tunnel）. Differences in general information，clinical indicators and ultrasound parameters were analyzed between the two groups. The diagnostic model was established with ultrasound parameters and clinical indicators using univariate and multivariate logistic analyses in a training cohort of 106 patients，to predict CTS within acromegaly. And ROC curve was used to evaluate the efficacy of the model in a test cohort of 26 patients with neurophysiological examination data. Results:Patients in clinical CTS group were older，with longer disease duration，higher levels of growth hormone 25-hydroxyvitamin D 3 and insulin-like growth factor-1 and were more likely to have impaired glucose tolerance relative to the no neurologic symptoms group（all P < 0.05）. Comparison between the two groups revealed significant differences in all ultrasound parameters：the CSA at the entrance of the MN carpal tunnel，the 1/3 of the forearm and the elbow were larger than the no neurological symptoms group（all P < 0.001），and the MN thickness ratio was greater observably in the clinical CTS group（ P < 0.001）. Greater thickness of the soft tissue at wrist and more blood flow signals in MN in carpal tunnel were revealed in clinical CTS group patients（ P < 0.001）.Combining the results of multifactorial logistic analysis，the multiparametric ultrasound combined with clinical index diagnosing model based on the predicted disease duration，CSA of MN at the entrance of carpal tunnel，MN thickness ratio and soft tissue thickness at the carpal tunnel was established to diagnose CTS combined with acromegaly. The ROC curve was plotted in the test cohort and the area under the curve for this model was 0.894. Conclusions:High-frequency ultrasound is sensitive to observe MN changes in acromegalic patients and the combination of multiparametric ultrasound and clinical index is useful for the non-invasive diagnosis of acromegalic patients with CTS.

Objective:To conduct a scope review of relevant studies on the application of virtual reality (VR) technology in breast cancer patients, identifying the basic content of interventions, outcome indicators, and application effects, with the aim of providing a reference for clinical healthcare professionals applying this technology.Methods:Based on the research methodology for scope reviews, a computer search was conducted in Chinese and English databases, including China National Knowledge Infrastructure, Wanfang Database, VIP, China Biology Medicine disc, PubMed, Web of Science, Cochrane Library, and Embase, with the search period extending to August 31, 2023. A categorical analysis of the included literature was conducted.Results:A total of 15 articles were included, primarily discussing the effects of VR technology on breast cancer patients' physical health, psychological well-being, cognitive function, and quality of life. Intervention frequencies were mainly once or twice daily, or twice weekly, with intervention durations ranging from 10 to 90 minutes and intervention periods from 2 to 12 weeks. VR interventions were found to improve physical function, psychological health, and cognitive function to some extent, increase patient rehabilitation adherence and satisfaction, and improve quality of life.Conclusions:VR technology can be an effective tool to support the treatment of breast cancer patients. However, the design of intervention protocols needs improvement. Future large-sample, multi-center, long-term follow-up randomized controlled trials are needed to verify the application effects of VR technology for breast cancer patients and promote its clinical application.

Objective:To investigate the pathway of self-disclosure to posttraumatic growth in patients after cervical cancer surgery, and to provide reference for improving the level of posttraumatic growth in patients.Methods:A convenient sampling method was used to investigate 300 patients with cervical cancer after surgery in Shandong Provincial Hospital Affiliated to Shandong First Medical University from June to November 2022 by using general data questionnaire, Distress Disclosure Index (DDI), Connor-Davidson Resilience Scale (CD-RISC), the Shortened Chinese Version of the Family Resilience Assessment Scale (FRAS-C) and the Posttraumatic Growth Inventory (PTGI) in a cross-section study.Results:A total of 290 valid questionnaires were collected, with an effective recovery rate of 96.7%. The patients were aged 23-70(48.13 ± 10.39) years. The scores of self-disclosure, resilience, family resilience and posttraumatic growth were (46.41 ± 9.82), (67.06 ± 14.63), (108.18 ± 11.06) and (58.24 ± 17.86) respectively. The results of pathway analysis showed that self-disclosure could not only directly predict posttraumatic growth, but also indirectly predict posttraumatic growth through the mediating role of resilience and family resilience, and the chain mediating role of resilience and family resilience, respectively. The direct effect of self-disclosure on posttraumatic growth was 0.236(95% CI 0.138-0.335), and the chain mediating effect of family resilience and resilience between self-disclosure and posttraumatic growth was 0.036(95% CI 0.018-0.060). Conclusions:Medical staff should not only consider the direct influence of self-disclosure on posttraumatic growth, but also pay attention to improve the resilience and family flexibility of patients after cervical cancer surgery, so as to promote their posttraumatic growth.

Objective:To explore the relationship between hematocrit, early fluid therapy, and clinical outcomes in patients with septic shock, and to provide evidence for fluid resuscitation therapy and prognosis assessment in these patients.Methods:The clinical information of patients with septic shock who were diagnosed and treated in the Emergency Intensive Care Unit (EICU) of the First Affiliated Hospital of Wenzhou Medical University from January 1, 2018 to December 31, 2020 were collected. Taking the survival or death of patients 28 days after admission as the end point of clinical research, the patients were divided into the survival and death groups. After analyzing the basic data of the two groups, the univariate and multivariate COX regression analyses were used to analyze the evaluation value of Δ Hematocrit (HCT) d2-d1 and ΔHCT d3-d1 on the prognosis of patients with septic shock. At the same time, the Kaplan-Meier survival curve was used to analyze the overall survival rate of patients with septic shock, and the smooth curve fitting graph was used to verify its relationship with net fluid intake and death. Results:There were 241 cases in the survival group and 67 cases in the death group. Univariate COX analysis showed statistically significant differences between the survival and death groups in acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ) ( P=0.0006), red cell volume distribution width (RDW) ( P=0.0043), age ( P=0.0184), ΔHCT d2-d1 ( P=0.0136), ΔHCT d3-d1 ( P=0.0204), and white blood cell (WBC) ( P=0.0444). Multivariate COX analysis showed that ΔHCT d2-d1 ( P=0.0115) and ΔHCT d3-d1 ( P=0.0029) were independent risk factors for death in EICU patients with septic shock. ΔHCT d2-d1 and ΔHCT d3-d1 were divided into three groups according to the three-digit method. The Kaplan-Meier survival curve showed no significant difference among the three groups in the overall survival rate related to ΔHCT d2-d1 ( P=0.16), but there was a statistically significant difference in the overall survival rate among the three groups related to ΔHCT d3-d1 ( P=0.025). The smooth fitting curve of ΔHCT d3-d1, net fluid intake, and prognosis showed that ΔHCT d3-d1 was negatively correlated with net fluid intake, and the middle ΔHCT d3-d1 group had the best prognosis. Conclusions:The value of ΔHCT d3-d1 is related to the net fluid intake of patients with septic shock. An appropriate decrease in HCT on the third day can improve the prognosis of patients with septic shock. The dynamic changes of hematocrit can provide a certain basis for fluid resuscitation and prognosis evaluation in patients with septic shock.

Objective To investigate the iodine intake level and the prevalence of thyroid nodules in Harbin City,and to study the correlation between the concentration of urinary iodine and the prevalence of thyroid nodules.Methods In Harbin,18 communities were randomly selected and specimens were collected from fasting morning urine from 2015 to 2017.The urine iodine concentration (UIC) was detected by arsenic cerium catalytic spectrophotometry,and the thyroid nodule was examined by B ultrasound.Results A total of 2 552 residents aged (45.79 ± 12.06) years old agreed to participate in the study,including 371 males and 2 181 females.The median UIC in all participants was 159.8 μg/L,there was a significant difference in urine iodine frequency distribution among age groups (x2 =40.097,P ＜ 0.01).Furthermore,the median UIC in male was 166.6 μg/L,and in female was 156.2 μg/L.There was a significant difference in UICs between male and female (U =2.122,P ＜ 0.05).The prevalence of total thyroid nodules in all participants was 48.75％ (1 244/2 552),and the standardized rate was 40.55％.Significant difference in the detection rate of thyroid nodules was observed among age groups (x2 =114.922,P ＜ 0.01),and there was a positive and significant correlation between the detection rate of thyroid nodules and increasing age (xtrand =111.746,P ＜ 0.01).Furthermore,in male,41.24％ (153/371) had thyroid nodules,with standardized prevalence rate of 41.13％,and in female,50.02％ (1 091/2 181) had thyroid nodules,with standardized prevalence rate of 49.20％.Likewise,there was a significant difference in the detection rate of thyroid nodules between male and female(x2 =9.790,P ＜ 0.01).The detection rate of thyroid nodules in the iodine deficient population (urinary iodine was 0-＜ 100 μg/L) was 55.58％ (244/439),and the incidence of thyroid nodules in the iodine adequate or optimal population (urinary iodine was 100-＜ 200 μg/L) was 46.68％ (591/1 266).Conclusions The total iodine level of the population in Harbin City of Heilongjiang Province is at adequate level.The detection rate of thyroid nodules is high and it is increased with age.The detection rate of thyroid nodules is higher in female than male.Regular detection of urine iodine and adjusting iodine nutrition will help prevent thyroid nodules.
