Objective:To analyze the etiological composition and clinical characteristics of infant hypertension，and provide reference for its diagnosis and treatment.Methods:This is a retrospective case-control study.Retrospective investigation and analysis were conducted on the clinical data of infants discharged from Beijing Children's Hospital Affiliated to Capital Medical University with a diagnosis of "hypertension" from June 1，2016 to September 30，2021，including clinical manifestations，auxiliary examinations，treatment plans，and prognosis.Results:A total of 74 eligible children were collected，including 42 male infants（56.8%）and 32 female infants（43.2%）.A total of 67 cases（90.5%）had clear secondary factors，including 35 cases of kidney disease（47.3%），12 cases of connective tissue disease（16.2%），and 9 cases of hematological tumor disease（12.2%）.At the beginning of the disease，cardiac ultrasound showed that 54 cases（73.0%）had ventricular wall thickening，including mild thickening in 31 cases（57.4%），moderate thickening in 11 cases（20.3%），and severe thickening in 12 cases（22.2%）.After grouping by etiology，the incidence of proteinuria and severe hypertension in the renal hypertension group，as well as those receiving multiple antihypertensive drugs，was significantly higher than that in the non-renal hypertension group（ χ 2=28.493， P<0.001； χ 2=17.283， P<0.001； χ 2=17.358， P<0.001）；Renal disease was risk factor for severe hypertension in infants according to univariate and multivariate logistic regression analysis respectively（ OR=11.176，95% CI：2.882~43.339， P<0.001； OR=11.669，95% CI：2.921~46.624， P<0.001）.Thirty-one children had follow-up records for 6 months or more，and 13（41.9%）still required antihypertensive treatment，of whom 26（83.9%）were no longer recorded as having elevated blood pressure. Conclusion:Infant hypertension is mainly secondary，with a high proportion of renal factors and predisposition to severe hypertension，which requires multiple antihypertensive drugs for control.Active antihypertensive treatment and removal of secondary factors during the acute phase are helpful for controlling hypertension in infants，but further research is needed on treatment options and long-term prognosis.

Paraplegia caused by spinal cord injury is a serious neurological complication, for which surgery is currently the main treatment method. Due to different surgical approaches, patients are usually expected to maintain a passive prone position for a long time or switch between the supine and prone positions. Affected by multiple factors such as neurogenic sensory disorders, pathological changes in muscle tone and operative duration, the risk of intraoperative acquired pressure injury (IAPI) is significantly increased. Current clinical prevention strategies for IAPI in these patients predominantly focus on localized pressure relief during positioning, lacking systematic, standardized comprehensive prevention protocols or evidence-based guidelines. To address it, Department of Nursing, Orthopedics Branch, China International Exchange and Promotive Association for Medical and Health Care, Spinal Trauma Professional Committee, Orthopedics Branch, Chinese Medical Doctor Association, Nursing Group of Spine and Spinal Cord Professional Committee of Chinese Association of Rehabilitation Medicine organized experts in relevant fields to formulate Guideline for the prevention of intraoperative acquired pressure injury in paraplegic patients with spinal cord injury ( version 2025), based on evidence-based medical evidence and latest research results and clinical practice at home and abroad. Eleven recommendations were put forward from the aspects of preoperative risk assessment, intraoperative prevention strategies, postoperative handover and monitoring, and supportive mechanisms for IAPI prevention, aiming to standardize the prevention measures and management strategies of IAPI in paraplegic patients with spinal cord injury and accelerate the recovery of patients and improve the therapeutic effect.

Objective:To compare the efficacy and safety of a domestic hair follicle extraction system versus traditional follicular unit excision (FUE) in extracting hair follicles for the treatment of androgenetic alopecia (AGA) .Methods:A multicenter, randomized, self-controlled clinical trial was conducted on AGA patients aged 18 - 59 years who were recruited from the Huashan Hospital, Fudan University, the Affiliated Hangzhou First People's Hospital, and the China-Japan Friendship Hospital between June 2023 and September 2024. Each patient's scalp was randomly divided into two sides (experimental side vs. control side) using an envelope method. The experimental side underwent robotic hair transplantation with a domestic hair follicle extraction system, and the control side underwent traditional FUE. Hair follicles were extracted from the safe donor area in the occipital region, and implanted into the ipsilateral hair loss area. The primary outcome was the hair transection rate which was calculated immediately after follicular extraction. The secondary outcomes included the hair follicle unit loss rate and the change in hair density at the recipient site on postoperative day 14. Safety was evaluated by assessing the incidence of folliculitis at the donor site on postoperative day 14 and the overall incidence of adverse events. Surgical outcomes were evaluated at 9 months after surgery. Comparisons of evaluation indicators among groups were performed by using a paired t test or Wilcoxon signed-rank test. Results:A total of 55 patients with AGA (51 males and 4 females, aged 32.71 ± 5.75 years) completed the hair follicle transplantation and postoperative follow-up. The hair transection rate ( M[ Q1, Q3]) was 6.65% (4.56%, 10.16%) in the experimental group and 5.28% (3.04%, 8.89%) in the control group (difference = 1.24%, 95% CI: -0.24%, 2.65%) . The hair follicle unit loss rate was 2.00% (1.00%, 3.50%) in the experimental group and 0.50% (0, 2.00%) in the control group, with a significant difference between the two groups ( P = 0.008) . On postoperative day 14, there was no significant difference in the hair density between the experimental group and control group (72.20 ± 25.95 per cm 2vs. 76.49 ± 30.84 per cm 2, P = 0.173) . At 9-month follow-up, both groups showed improvement in the investigator's overall score in the recipient areas. Seven adverse events occurred in 7 subjects (12.72%) in each group, and all were mild folliculitis. Conclusion:The domestic hair follicle extraction system demonstrated comparable efficacy and safety to the traditional FUE in hair transplantation.

Objective To determine the effect of rapamycin(Rapa) on JAK2, ABCA3, and the immune checkpoint PD-1/PD-L1 in exosomes derived from JAK2 V617F positive HEL cells. Methods Human erythroleukemia HEL cells (JAK2 V617F mutation-positive) were cultured in vitro, and rapamycin was added at concentrations of 10, 50, and 100 nmol/L. The control group was established and cell proliferation inhibition rate was detected by CCK-8. Based on the inhibition rate of cell proliferation, cells intervened with 10 and 50 nmol/L Rapa were selected. Exosomes were extracted using a kit and identified by Western blot and flow cytometry. JAK2, ABCA3, and PD-1/PD-L1 mRNA changes in exosomes were detected by fluorescent quantitative PCR. The expression of exosome PD-1/PD-L1 protein was determined by flow cytometry. Results The exosomes extracted with the exosome kit all expressed characteristic CD9, CD63, and CD81 proteins, which were consistent with the general characteristics of exosomes. JAK2 mRNA can be detected in exosomes from HEL cells; Rapa reduced exosome production by HEL cells, and dose-dependently decreased gene expression of JAK2, ABCA3, and PD-L1 in exosomes. In addition, Rapa inhibited exosomal PD-L1 protein expression and had no significant effect on PD-1 protein expression. Conclusion HEL cells may transmit JAK2 mutant gene signals via exosomes. Rapa can reduce the production of exosomes and inhibits JAK2 mutated signals delivered by exosomes and suppresses PD-L1 protein expression.

Objective:To discuss the emergency nursing management procedure in Department of Microsurgery during novel coronavirus pneumonia(COVID-19) and evaluate the effect of the prevention and control procedures.Methods:From January, 20- February 20, 2020, in order to prevent the medical staff and patients from infection of COVID-19, prevention and control measures were put in place which included screening and diagnosis of emergency pa- tients at the Department of Emergency through check body temperature and lung CT scan, monitoring body temperature and finger blood oxygen saturation on all inpatients and their accompanies, confirming the diagnosis and quarantine the patients who were in high temperature with abnormal lung CT scans, disinfecting and summary disinfection of the quaran- tine wards where suspected patients stayed, training medical staff for personal protections, standardizing the use and man- agement of personal protection equipment (PPE), managing medical staff in wards, educating patient about the COVID-19 to relive their nervousness, etc.Results:Of the 4 patients with persistent fever, 2 were diagnosed as new coronavirus infection. Of the 2 COVID-19 patients, 1 had confirmed diagnosis and transferred, the other who with highly suspected COVID-19 was quarantined at home. All medical staffs were trained with COVID-19 prevention and control proce- dures, with a qualification rate at 100%. Fourty-eight medical staffs were put on front-line duty and the rest of 17 were put on standby. Apart from one medical staff had been infected at the early phase of COVID-19, no one was in- fected after the emergency management and protective measures were implemented. All medical devices were used strictly to follow the controlled procedures. All patient wore masks.Conclusion:During the COVID-19 epidemic, emergency management measures were taken to avoid cross infection in hospital, which ensured the safety of medical staff and patients. The COVID-19 prevention and control measures were practical, in time and effective.

Objective? To design a satisfaction scale on nutrition support nursing service for inpatients, and establish a structural equation model of inpatient satisfaction with nutrition support nursing service in central city area to test the scale, so as to construct a tool for evaluating the satisfaction with nutrition support nursing service. Methods? This study selected 18 indicators affecting the satisfaction with nutrition support nursing services of inpatients based on the European Customer Satisfaction Index (ECSI), the American Customer Satisfaction Index (ACSI) Model, and the China Customer Satisfaction Index Model. From September to December of 2017, a convenience sampling investigation was carried out among the inpatients receiving nutritional support in a Class?Ⅲ Grade A medical institution. Through factor analysis, the 18 impact indicators were categorized into 6 dimensions, namely, perception of nutrition support nursing quality, nursing expectations, nutrient support nursing brands, nutrient support nursing service satisfaction, patient nutrient support nursing loyalty, patient nutrient support nursing complaints. Results? A structural equation model for satisfaction of nursing support services for inpatients was constructed, and the rationality of the 6 dimensions was verified. The Cronbach's α indexes of the 6 dimensions were all equal or greater than 0.80. KMO test coefficient was 0.745. Bartlett spherical test results showed χ2=3 402.132 (P＜0.01). The reasonableness of the six dimensions was verified, and the fitting effect of the model was good (χ2/df=1.416, RMS of residual=0.030, goodness of fit index=0.945, adjusting goodness of fit index=0.927, standard fitting index=0.947, value-added fitting index=0.984, comparing fitting index=0.984, root mean square of approximate error=0.035). Conclusions? With this model, nurse managers can identify the factors affecting the satisfaction of patients receiving nutritional support, and propose continuous improvement strategies that will help improve the effectiveness of nursing services, and improve patient satisfaction with inpatient nutritional support, so as to provide reference for the research of satisfaction model for inpatients.

Objective To investigate the status quo of nutritional risks, malnutrition and nutritional support of inpatients with neoplasms and to provide a theoretical basis for making targeted clinic nutritional support standards and training programs.Methods Totally 421 patients with neoplasms who were admitted in Wuhan Union Hospital Affiliated to Tongji Medical College, Huazhong University of Science and Technology between October 2015 and April 2016 were selected as respondents by cross-sectional survey and convenience sampling, and investigated with self-made nutritional support questionnaires based on Nutritional Risk Screening 2002 (NRS 2002) and China's real nursing practice.Results The incidence of malnutrition of the 421 patients was 44.2%, and the incidence of nutritional risks was 68.6%. The incidence of nutritional risks of patients with gastrointestinal neoplasms was higher than that of those patients with other neoplasms (χ2=24.541, 4.405;P<0.05); 92.6% of patients received nutritional support, 76.2% of which received parenteral nutrition and 14.5% received enteral nutrition; the incidence of gastrointestinal complications among those patients who received enteral nutrition was up to 30.2%, and the incidence of mechanical complications among those patients who received parenteral nutrition was up to 13.4%; the nursing achievement rates of the patients who received enteral nutrition and parenteral nutrition were 41.8% and 61.6%, respectively.Conclusions Inpatients with neoplasms show high incidence of nutritional risks and malnutrition. Therefore, healthcare workers should standardize the nutritional risk management for inpatients with neoplasms and strengthen the nutrition nursing training and quality control for nurses so as to reduce nutritional support-related complications among inpatients with neoplasms and accelerate their recovery.

AIM:To explore the expression and possible function of histamine H3 receptor (H3R) in striated myogenesis and the differentiated C2C12 cells.METHODS: H3R and myogenesis late marker myosin heavy chain (MHC) were detected at mRNA and protein levels during C2C12 myogenesis.H3R antagonist ciproxifan was added and the expression of the myogenesis early marker desmin, intermediate markers myogenin and MHC was detected.Differentia-ted myoblasts were loaded with Fluo-4 calcium indicator dye and the effect of R-( a)-methylhistamine ( RMeHA) on the cy-toplasmic calcium concentration was determined under the 200 mA electrical stimulation.RESULTS: The expression of H3R and MHC was increased during myogenesis.Ciproxifan incubation had no influence on the 3 striated myogenesis mar-kers (P>0.05).In C2C12 myoblasts, RMeHA (10 nmol/L~100 μmol/L) effectively diminished cytoplasmic calcium peak when the cells were electrically paced (P<0.05).The best inhibitory effect of RMeHA was observed at dose of 100 nM for 10 min and 20 min, which was higher than that for 5 min (P<0.05).CONCLUSION: H3R might have little effect on the myogenic differentiation, but diminishes cytoplasmic calcium peak of the differentiated myoblasts under electri-cal stimulation.
