Objective To understand the current situation of human brain donation in Hebei Province by analyzing the basic information of Human Brain Bank samples of Hebei Medical University in order to provide basic data support for subsequent scientific research.Methods The samples collected from the Human Brain Bank of Hebei Medical University were analyzed(from December 2019 to February 2024),including gender,age,cause of death,as well as quality control data such as postmortem delay time,pH value of cerebrospinal fluid and and RNA integrity number and result of neuropathological diagnosis.Results Until February 2024,30 human brain samples were collected and stored in the Human Brain Bank of Hebei Medical University,with a male to female ratio of 9∶1.Donors over 70 years old accounted for 53％.Cardiovascular and cerebrovascular diseases(36.67％)and nervous system diseases(23.33％)accounted for a high proportion of the death causes.The location of brain tissue donors in Shijiazhuang accounted for 90％donations,and the others were from outside the city.The postmortem delay time was relatively short,90％within 12 hours and 10％more than 12 hours.69.23％of the brain samples had RNA integrity values greater than 6.Cerebrospinal fluid pH values ranged from 5.8 to 7.5,with an average value of 6.60±0.45.Brain weights ranged from 906-1496 g,with an average value of(1210.78±197.84)g.Three apolipoprotein E(APOE)alleles were detected including five genotypes(ε2/ε3,ε2/ε4,ε3/ε3,ε3/ε4,ε4/ε4).Eleven staining methods related to neuropathological diagnosis had been established and used.A total of 12 cases were diagnosed as neurodegenerative diseases(including Alzheimer's disease,Parkinson's disease,multiple system atrophy,corticobasal degeneration and progressive supranuclear palsy,etc.),accounting for 40％donated brains.The comorbidity rate of samples over 80 years old was 100％.Conclusion The summary and analyses of the data of brain donors in the Human Brain Bank of Hebei Medical University can reflect the current situation of the construction and operation of the brain bank in Hebei Province,and it can also be more targeted to understand and identify potential donors.Our information can provide reference for the construction of brain bank and provides more reliable materials and data support for scientific research.

With the population ageing, the number of elderly with noncommunicable diseases and functional disabilities is increasing. The assistive technology can improve the ability of older adults for daily living activities and reduce dependence on caregivers to facilitate home-based care for the elderly. However, the provision of assistive technology service in China is still in the early stage and lacks implementable model. This article introduces international experiences on the delivery of assistive technology service, and discusses the status quo and problems of assistive technology service in China, to provide insights for promoting assistive technology service in the primary health care.

Objective:To systematically observe the location and severity of perineal lacerations during childbirth and explore the relationship between the length/depth and the degrees of perineal lacerations.Methods:This prospective study recruited full-term singleton cephalic pregnant women planning vaginal delivery at the Fourth Hospital of Shijiazhuang from March 2023 to July 2023. Before the second stage of labor, the perineal body length (PBL) was measured. After delivery, the locations of all birth canal lacerations, the perineal skin lacerations length (PSLL), and the perineal lacerations depth (PLD) were measured and recorded. A magnifying glass was used to identify the layers of the skin and photographs were taken if necessary. Statistical methods such as t-test, rank-sum test, and Chi-square test (or Fisher's exact test) were used to compare the basic conditions and birth canal lacerations between primiparous and multiparous women. The receiver operating characteristic (ROC) curve was used to analyze the sensitivity and specificity of PSLL, PLD, and the PSLL/PBL ratio. Results:During the study period, 200 women were included, of which 189 had vaginal deliveries (173 primiparous and 16 multiparous) and 11 had emergency cesarean sections (10 primiparous and one multiparous). Among the 173 primiparous women with vaginal deliveries, 33 (19.1%) underwent episiotomy, and the other 140 (80.9%) had perineal lacerations. Among these cases of perineal lacerations, nine were complicated by vaginal wall lacerations, 20 by labial lacerations, and four by clitoral and urethral lacerations. There were 32 (22.9%) primiparous women with first-degree perineal lacerations and 108 (77.1%) with second-degree perineal lacerations. Among the 16 multiparous women who delivered vaginally, two had intact birth canals without lacerations, and 14 had perineal lacerations (eight with first-degree and six with second-degree perineal lacerations). Besides, none of them underwent episiotomy or assisted vaginal delivery. The rates of episiotomy and second-degree perineal lacerations were higher in primiparous women than in multiparous women [19.1% (33/173) vs. 0/16, 77.1% (108/173) vs. 6/14, Fisher's exact test, both P<0.05). The PSLL, PLD, and PSLL/PBL ratio were significantly lower in the primiparous women with first-degree perineal lacerations than in the primiparous women with second-degree perineal lacerations [0.0 mm (0.0-10.0 mm) vs. 30.0 mm (25.5-40.0 mm), 5.0 mm (1.5-10.0 mm) vs. 14.0 mm (10.0-15.0 mm), 0.0 mm (0.0-21.1 mm) vs. 63.6 mm (50.0-77.3 mm); Z values were－8.04,－6.46, and－7.75, respectively, all P<0.05]. The optimal cut-off values of PSLL, PLD, and PSLL/PBL ratio for differentiating between first-degree and second-degree perineal lacerations were 15 mm, 9 mm, and 33.33%, with the area under the ROC curve (AUC) of 0.965, 0.869, and 0.951 and the sensitivity of 91.67%, 91.67%, and 89.81%, respectively. The AUC of PSLL was significantly greater than that of PLD ( Z=2.55, P=0.011), but the AUC of PSLL/PBL ratio showed no significant difference with that of PSLL or PLD ( Z=1.18 and 1.89, both P>0.05). Conclusions:It is difficult for full-term primiparas to maintain perineal integrity during vaginal delivery. Measuring the PSLL, PLD, and PSLL/PBL ratio of primiparous women will be useful for distinction between first- and second-degree perineal lacerations.

Objective: To investigate the timing of pericardial drainage catheter removal and restart of the anticoagulation in patients with atrial fibrillation (AF) suffered from perioperative pericardial tamponade during atrial fibrillation catheter ablation and uninterrupted dabigatran. Methods: A total of 20 patients with pericardial tamponade, who underwent AF catheter ablation with uninterrupted dabigatran in Beijing Anzhen Hospital from January 2019 to August 2021, were included in this retrospective analysis. The clinical characteristics of enrolled patients, information of catheter ablation procedures, pericardial tamponade management, perioperative complications, the timing of pericardial drainage catheter removal and restart of anticoagulation were analyzed. Results: All patients underwent pericardiocentesis and pericardial effusion drainage was successful in all patients. The average drainage volume was (427.8±527.4) ml. Seven cases were treated with idarucizumab, of which 1 patient received surgical repair. The average timing of pericardial drainage catheter removal and restart of anticoagulation in 19 patients without surgical repair was (1.4±0.7) and (0.8±0.4) days, respectively. No new bleeding, embolism and death were reported during hospitalization and within 30 days following hospital discharge. Time of removal of pericardial drainage catheter, restart of anticoagulation and hospital stay were similar between patients treated with idarucizumab or not. Conclusion: It is safe and reasonable to remove pericardial drainage catheter and restart anticoagulation as soon as possible during catheter ablation of atrial fibrillation with uninterrupted dabigatran independent of the idarucizumab use or not in case of confirmed hemostasis.

OBJECTIVE: To observe the effects of moxibustion at "Baihui" (GV 20) and "Dazhui" (GV 14) at different time points on the serum level of β-endorphin (β-EP), substance P (SP) and expression of interleukin-1β (IL-1β) and cyclooxygenase-2 (COX-2) protein in brainstem in rats with migraine, and to explore the effect and mechanism of moxibustion in preventing and treating migraine. METHODS: Forty male SD rats were randomly divided into a blank group, a model group, a prevention+treatment (PT) group and a treatment group, 10 rats in each group. Except the blank group, the rats in the remaining groups were injected with nitroglycerin subcutaneously to prepare migraine model. The rats in the PT group were treated with moxibustion 7 days before modeling (once a day) and 30 min after modeling, while the rats in the treatment group were treated with moxibustion 30 min after modeling. The "Baihui" (GV 20) and "Dazhui" (GV 14) were taken for 30 minutes each time. The behavioral scores in each group were observed before and after modeling. After intervention, ELISA method was used to detect the serum level of β-EP and SP; the immunohistochemistry method was used to detect the number of positive cells of IL-1β in brainstem; the Western blot method was used to detect the expression of COX-2 protein in brainstem. RESULTS: Compared with the blank group, the behavioral scores in the model group were increased 0-30 min, 60-90 min and 90-120 min after modeling (P<0.01); compared with the model group, in the treatment group and the PT group, the behavioral scores were decreased 60-90 min and 90-120 min after modeling (P<0.01). Compared with the blank group, in the model group, the serum level of β-EP was decreased (P<0.01), while the serum level of SP, the number of positive cells of IL-1β in brainstem and the expression of COX-2 protein were increased (P<0.01). Compared with the model group, in the PT group and and the treatment group, the serum level of β-EP was increased (P<0.01), while the serum level of SP, the number of positive cells of IL-1β and the expression of COX-2 protein in brainstem were decreased (P<0.01, P<0.05). Compared with the treatment group, in the PT group, the serum level of β-EP was increased and COX-2 protein expression was decreased (P<0.05). CONCLUSION Moxibustion could effectively relieve migraine. The mechanism may be related to reduce the serum level of SP, IL-1β and COX-2 protein expression in brainstem, and increase the serum level of β-EP, and the optimal effect is observed in the PT group.

Objective To investigate the clinical features of hypopituitarism with nonalcoholic fatty liver disease (NAFLD) in children after sellar tumor surgery and the association between hypopitarism and NAFLD in children. Methods A retrospective analysis was performed for the clinical data of children with hypopituitarism and NAFLD after sellar tumor surgery who were followed up regularly in Wuhan Children's Hospital, Tongji Medical College, Huazhong University of Science and Technology, from January 2017 to December 2021, and their clinical features were analyzed. Results There were 32 children with regular follow-up and complete clinical data after sellar tumor surgery, and 10 children (31.25%) developed NAFLD, among whom there were 5 boys and 5 girls. Among these 10 children, 9 had craniopharyngioma and underwent surgical treatment, and 1 had germinoma and underwent local radiotherapy. The 10 children had a median age of 8.4(6.29.8) years at the diagnosis of hypopituitarism and a median age of 11.9(8.7-12.6) years at the diagnosis of NAFLD. The median number of years from the diagnosis of hypopituitarism to the diagnosis of NAFLD was 2.0(1.4-4.0) years. At the diagnosis of NAFLD, all 10 children had obesity, and body mass index (BMI) was increased by 7.26±4.25 kg/m 2 on average since the diagnosis of hypopituitarism; the 10 children had a mean fasting blood glucose level of 4.67±0.55 mmol/L, a mean fasting insulin level of 25.40±5.93 μIU/ml, and a mean HOMA-IR index of 5.26±1.29. Among these 10 children, 9 had hypertriglyceridemia, and 1 had elevated triglyceride, with a mean level of 3.08±1.09 mmol/L; 6 children had hypercholesterolemia, with a mean level of 5.67±1.25 mmol/L; 8 children had high-density lipoprotein cholesterolemia, with a mean level of 3.97±1.27 mmol/L. After the diagnosis of NAFLD, 2 children were treated with recombinant human growth hormone and metformin and achieved reductions in BMI, HOMA-IR, and triglyceride after treatment, and total cholesterol and low-density lipoprotein cholesterol were reduced to the normal range. Conclusion Children may experience weight gain, hypopituitarism, insulin resistance, and dyslipidemia after sellar tumor surgery, which may lead to the onset of NAFLD. Weight management and active pituitary hormone replacement therapy are recommended for such children, as well as routine screening and management of fatty liver disease.
