BACKGROUND: Stroke is the leading cause of death and long-term disability worldwide, including China. This study aimed to provide timely updates on stroke burden and stroke-related risk factors to help improve population-based prevention and control strategies. METHODS: Based on the Global Burden of Disease study 2021, incidence rate, prevalence rate, mortality rate, and disability-adjusted life-year (DALY) rate were used to estimate stroke burden trend from 1990 to 2021. RESULTS: In 2021, China had 4.1 million incident stroke cases, 26.3 million prevalent stroke cases, 2.6 million stroke related deaths, and 53.2 million stroke related DALYs, compared to 11.9 million incident stroke cases, 93.8 million prevalent stroke cases, 7.3 million stroke related deaths, and 160.5 million stroke-related DALYs worldwide. In 2021, the top six risk factors contributing to stroke burden were high blood pressure, air pollution, tobacco consumption, dietary risk factors, high low-density lipoprotein cholesterol, and high fasting plasma glucose, both in China and worldwide. From 1990 to 2021, China had significant increases of incidence rate, prevalence rate, mortality rate, and DALY rate for stroke, with estimates of 100.6 (95% uncertainty intervals [UI]: 87.2, 114.1)%, 102.9 (95% UI: 95.5, 110.9)%, 40.0 (95% UI: 14.9, 72.3)% and 15.7 (95% UI: -4.6, 41.2)%, respectively, while global incidence rate, prevalence rate, mortality rate and DALY rate for total stroke showed relatively moderate increases or even decreases, with estimates of 15.0 (95% UI: 12.1,18.0)%, 25.8 (95% UI: 23.7, 28.0)%, -2.6 (95% UI: -10.6, 5.5)%, and -10.7 (95% UI: -17.7, -3.6)%, respectively. CONCLUSION Stroke remains a huge disease burden worldwide and in China, and compared to the worldwide China has a significantly higher burden of stroke.

OBJECTIVE: To compare the impact of different peroneus longus tendon (PLT) stump management techniques on ankle function following arthroscopic anterior cruciate ligament (ACL) reconstruction with autologous PLT grafts. METHODS: A retrospective analysis was conducted on 60 patients with ACL rupture who met the inclusion criteria between August 2020 and July 2024. All patients underwent arthroscopic ACL reconstruction using the autologous PLT grafts. Patients were assigned to group A [PLT stump sutured to peroneus brevis tendon (PBT), n=30] or group B (no stump intervention, n=30). The two groups showed no significant difference ( P>0.05) in baseline data, including gender, age, body mass index, injury mechanism, affected side, preoperative American Orthopaedic Foot and Ankle Society (AOFAS) score, ankle muscle strength, ankle range of motion, and arch-related angles. Postoperative outcomes were assessed using the AOFAS score, ankle muscle strength (eversion and first-ray plantar flexion), arch-related angles (medial/lateral longitudinal and anterior/posterior arch), ankle range of motion (eversion, inversion, dorsiflexion, plantarflexion), and limb symmetry index (LSI). Change values in muscle strength, arch-related angles, and range of motion from preoperative to 12 months postoperatively were calculated for intergroup comparison. RESULTS: Groups A and B had comparable PLT graft lengths and diameters ( P>0.05). All patients were followed up 13-16 months (mean, 14.5 months). Postoperative complications included 1 case of incision infection, 1 case of deep vein thrombosis, and 1 case of knee stiffness in group A, 1 case of knee stiffness in group B. There was no significant difference in the overall complication incidences between groups ( P>0.05). No significant difference was found in the AOFAS scores between different time points and between groups ( P>0.05). At 12 months after operation, neither group showed significant changes from preoperative baseline in ankle strength, range of motion, or arch-related angles, and there was no significant difference in these change values between groups ( P>0.05). There was no significant difference in LSI between the two groups at 6 or 12 months postoperatively ( P>0.05). CONCLUSION Both suturing and leaving the PLT stump untreated during arthroscopic ACL reconstruction provided comparable ankle outcomes and well-preserved foot and ankle function.

  Objective  This study aimed to investigate Chinese anesthesiologists' comprehension of palliative care and their experiences with palliative sedation for patients in the end-stage of life.  Methods  From October to December 2021, a national cross-sectional survey was conducted among anesthesiologists in China distributed by the Chinese Society of Anesthesiology, Chinese Medical Association with convenient sampling. The survey questionnaire encompassed general information, professional experience, familiarity with palliative care, emotional responses to end-stage cases, experience with sedation for critically ill or end-stage patients, and preferences for sedation medication.  Results  A total of 2536 anesthesiologists from 29 provinces in China completed valid questionnaires. Among them, 572 anesthesiologists(22.6%, 572/2536) reported familiarity with palliative medicine. Male anesthesiologists, as well as those with prior experience in caring for critically ill or end-stage patients, involved in pain management and practicing in hospitals with established institutional palliative care teams, demonstrated greater familiarity with palliative care concepts(all P<0.05). Over 40% of respondents felt powerless, helpless, and indecisive when confronted with end-stage patients. Anesthesiologists knowledgeable about palliative care exhibited greater confidence in managing critically ill or end-stage patients(9.8% vs. 4.4%, P=0.001). Among the anesthesiologists surveyed, 734 had administered sedation to end-stage patients, with 151 of them(20.6%, 151/734) inappropriately relying solely on opioids for sedation.  Conclusions  The understanding of palliative care and palliative sedation medication choice among anesthesiologists in China is still very limited. The establishment of palliative care teams, provision of education and training in palliative care, and enhancement of familiarity with palliative principles may bolster anesthesiologists' confidence when encountering critically ill or end-stage patients and subsequently enhance the quality of care for patients in the terminal stages of life.

Objective To investigate clinicians'practice and opinions on sedation therapy in end-stage patients at Peking Union Medical College Hospital.Methods From August,2022 to April,2023,an online questionnaire survey was conducted among clinicians involved in end-stage patient management.Results A total of 205 questionnaires were distributed,with an effective response rate of 56.1% .Among the clinicians,55.7% of them had experience of applying sedation therapy in end-stage patients;85.2% of clinicians believed that se-dation could relieve the suffering of terminal patients from physical refractory symptoms;75.7% of clinicians considered that sedation therapy could be used to relieve agony from psycho-existential distress.Most clinicians had concerns about sedation therapy due to the lack of legal support(86.1% )and the lack of understanding of patients or families(59.1% ).The majority(90.4% )of clinicians were willing to receive training on palliative sedation.Conclusions A majority of clinicians agree that sedation therapy could relieve the physical distress and psycho-existential distress in end-stage patients.However,most clinicians have concerns about the application of sedation therapy due to the lack of legal support.It is necessary to enhance the training on palliative sedation.

Objective To explore the mechanism of Yangxue Qingnao Granules(Siwu Decoction modified)in the treatment of hypertension based on network pharmacology and molecular docking.Methods The chemical composition analysis results of Yangxue Qingnao Granules in the early stage of the research group were used as the basis for the screening of active compounds.The oral bioavailability≥30%and drug-likeness≥0.18 were used as the screening conditions,and the blood components were supplemented in combination with the literature.TCMSP,chemical professional database and SWISS database were used to predict the targets of potential active compounds of Yangxue Qingnao Granules.Hypertension-related targets were obtained through GeneCards and DiGSeE databases.The intersection of the targets related to hypertension disease and the targets of the potential active compounds of Yangxue Qingnao Granules(common targets)is the potential target of Yangxue Qingnao Granules for the treatment of hypertension.The potential targets were matched with the potential active compounds of Yangxue Qingnao Granules to obtain the antihypertensive active compounds of Yangxue Qingnao Granules.PPI analysis was performed on the potential targets of serum brain granules in the treatment of hypertension through the STRING database,and the core targets were screened according to the degree value.The David database was used to analyze the GO function and KEGG pathway enrichment of the core targets.The core targets with the top six degrees were selected as the docking target proteins,and molecular docking verification was performed with the antihypertensive active compounds.Results A total of 32 potential active compounds,161 active compound targets and 1 539 hypertension-related targets were obtained.After intersection,88 potential targets(common targets)of Yangxue Qingnao Granules in the treatment of hypertension were obtained,involving 29 antihypertensive active compounds.PPI analysis screened 14 core targets:PPARG,ACHE,IL4,CCL2,JUN,NOS3,APP,IL1B,CAT,PTGS2,CASP3,TP53,TNF,IL6,involving 158 GO entries and 13 signaling pathways.Five key active ingredients,chlorogenic acid,rosmarinic acid,paeoniflorin catechinic acid and aloe emodin,were obtained by molecular docking,which were combined with PTGS2,CASP3,TNF,CAT,TP53 and IL6,respectively.Conclusion Yangxue Qingnao Granules may act on core targets such as PTGS2 and CASP3 through key active components such as chlorogenic acid and rosmarinic acid,regulate key pathways such as TNF signaling pathway,MAPK signaling pathway and Toll-like receptor signaling pathway,and play a role in the treatment of hypertension through anti-inflammatory effects.

Severe acute pancreatitis(SAP)is a critical condition in general surgery settings,characterized by high mortality and poor prognosis.On February 28,2024,the Department of Hepatobiliary Surgery at the First Affiliated Hospital of Harbin Medical University admitted a 36-year-old male patient.The patient presented with"upper abdominal pain accompanied by fever for three months and jaundice of the skin and sclera for one week."Physical examination revealed 11 puncture tubes,and a palpable mass measuring 3 cm × 5 cm in the upper abdomen.Enhanced CT and magnetic resonance cholangiopancreatography indicated acute pancreatitis.The patient was diagnosed with"SAP,infectious pancreatic necrosis,and biliary stenosis."He had severe abdominal infection and complex postoperative complications,making treatment challenging.Consequently,a multidisciplinary team(MDT)consultation was initiated.After three rounds of MDT consulfation and freating,the patient ultimately recovered successfully and was discharged.This article reviews the MDT treatment process for this patient and summarizes the characteristics of this condition based on relevant literature to provide insights and experience for clinical practice.

Objective To explore the application value of transperineal three-dimensional ultrasound combined with SWE in evalu-ating the effect of delivery mode on the morphology and function of levator ANI muscle in primipara,and to provide a new method for early diagnosis of pelvic floor dysfunction(PFD).Methods A total of 92 primiparas who were re-examined 6-8 weeks after delivery in our hospital were selected as postpartum group,and divided into vaginal delivery group(n=45)and cesarean section group(n=47)accord-ing to their delivery mode,and healthy women without childbirth at the same period were selected as control group(n=43).Transperineal three-dimensional ultrasound combined with SWE was used to examine the differences in the morphological parameters and elastic param-eters of levator anal hiatus in different states among all groups.Results The hiatus area of levator anal muscle(LHA)at rest,maximum anal retraction and maximum Valsalva in the vaginal delivery group was greater than that in the cesarean section group and control group,and the cesarean section group was greater than the control group,the differences were statistically significant(P＜0.01).Compared with control group and cesarean section group,the elastic parameters of vaginal delivery group at rest and maximum anal retraction were de-creased,the difference was statistically significant(P＜0.01).There was no significant difference in elastic parameters between the cesar-ean section group and the control group(P＞0.05).The difference between maximum Valsalva state and resting state LHA(Δ A')was negatively correlated with the difference before and after contraction of bilateral PR Young's modulus(ΔE)(left r=-0.444,P=0.008;Right r=0.488,P=0.002).Conclusion Three-dimensional perineal ultrasonography combined with SWE can quantitatively evaluate the morphology and function of levator ANI muscle,and provide evidence for the early diagnosis of PFD.

Objective:To investigate the effects of mild hypothermia on microglia polarization and janus kinase 2/signal transduction and transcriptional activation factor 3 (JAK2/STAT3) signaling pathway during cerebral ischemia-reperfusion (I/R) in rats.Methods:Forty-five clean-grade healthy male Sprague-Dawley rats, aged 8 weeks, weighing 260-280 g, were divided into 3 groups ( n=15 each) by the random number table method: sham operation group (S group), cerebral I/R group (I/R) and mild hypothermia group (H group). In I/R group and H group, cerebral I/R was induced by middle cerebral artery occlusion using a nylon thread in anesthetized animals, the nylon thread was removed to restore the perfusion after 2 h of occlusion, and the rectal temperature was maintained at 36-37 ℃ during the period. Group H was wiped with 75% alcohol for 3 h starting from the time point immediately after reperfusion, and the rectal temperature was maintained at 32-33℃. Modified neurological severity score (mNSS) was evaluated at 24 h of reperfusion. Animals were then sacrificed for determination of the cerebral infarct size (using TTC staining), expression of M1 marker inducible nitric oxide synthase (iNOS), M2 marker arginase 1(Arg-1), phosphorylated JAK2(p-JAK2)and phosphorylated STAT3(p-STAT3)(by Western blot), expression of iNOS mRNA and Arg-1 mRNA (by quantitative polymerase chain reaction), and contents of interleukin-6 (IL-6) and IL-10 (by enzyme-linked immunosorbent assay). Results:Compared with group S, mNSS and cerebral infarct size were significantly increased, the expression of iNOS, Arg-1 protein and mRNA in cerebral ischemic penumbral zone was up-regulated, and the p-JAK2/JAK2 ratio, p-STAT3/STAT3 ratio, and contents of IL-6 and IL-10 were increased in the other two groups ( P<0.05). Compared with I/R group, mNSS and cerebral infarct size were significantly decreased, the expression of iNOS protein and mRNA in cerebral ischemic penumbral zone was down-regulated, the expression of Arg-1 and mRNA was up-regulated, and the p-JAK2/JAK2 ratio, p-STAT3/STAT3 ratio and IL-6 content were decreased, and the IL-10 content was increased in group H ( P<0.05). Conclusions:Mild hypothermia can promote the polarization shift of microglia from M1 to M2 phenotype during cerebral I/R and inhibit the central inflammatory responses, and the mechanism may be related to inhibition of JAK2/STAT3 signaling pathway in rats.

Objective:To collect data on urinary flow rate in the elderly female population across the country and to analyze the range of reference values.Methods:This study enrolled 333 subjects from July 2020 to June 2022.The study implementation process was divided into two steps.In the first step, subjects completed an electronic questionnaire, which included basic information about the subject, a short form for urinary incontinence, and a scoring form for the symptoms of overactive bladder syndrome.In the second step, the staff introduced the use of a mobile uroflowmetric device and distributed the instrument and materials.Uroflow rate data were automatically uploaded to a cloud database via the mobile phone.Subsequently, two or more physicians specializing in urinary control performed Uroflow rate-qualifying screenings and conducted statistical analyses.Results:A total of 333 subjects were enrolled in the study, and the researchers collected 1375 qualified urine flow rate records using a mobile urine flow rate instrument.The age of the subjects ranged from 60 to 84 years, with a mean age of 69 years.The reference ranges for urinary flow rate were found to be 24.8-26.2 s, with a mean urinary flow rate of 12.2-12.9 ml/s, a maximum urinary flow rate of 22.2-23.4 ml/s, and a time to peak of 8.5-9.7 s. The study observed a tendency for both maximal and mean urinary flow rates to decrease in older women as their age increased(Pearson correlation coefficient: -0.1, P<0.001). Conclusions:The uroflow rate of older women decreases with aging.Specifically, the average uroflow rate of women over 80 years old is lower than that of other age groups.This study aims to establish normal uroflow parameters for uroflowmetry in healthy older women in China.

【Objective】 To analyze the risk factors of unplanned reintubation after the surgery of acute type A aortic dissection （ATAAD） and assess its predictive value. 【Methods】 The clinical data of 69 ATAAD patients， who underwent surgery in our department from January 2021 to June 2021， were retrospectively collected and analyzed. The operation procedure was performed based on the extent of dissection involved and the characteristics of aortic root lesions. The patients were divided into three groups based on whether weaning off ventilator and whether reintubation after weaning off. Perioperative and operative factors were compared among the three groups. 【Results】 The duration of surgery and circulatory arrest time were much longer in subjects of reintubation and those who did not wean off ventilator （P=0.005 and 0.036， respectively）. Compared to the group in which patients successfully weaned off ventilator， the first intubation time after surgery was longer ［（27.8（13.2， 71.1） h vs. 88.4（34.3， 114.9） h， P=0.013）］ and the use rate of non-invasive ventilator （NIV） was higher in reintubation group （P<0.001）. After adjusting for age， gender， BMI， hypertension， diabetes mellitus， chronic kidney diseases stage 5， and smoking， surgery time （OR=6.913， 95% CI：1.099， 43.484， P=0.039） and the use of NIV （OR=92.790， 95% CI： 4.932， 1 745.797， P=0.002） were independent risk factors for unplanned reintubation for ATAAD patients after surgery. Surgery duration > 7 h and the use of NIV could well predict the occurrence of unplanned reintubation. The area under ROC curve was 0.838 （95% CI： 0.729， 0.916）， the sensitivity and specificity were 83.3% and 84.2%， respectively. 【Conclusion】 Surgery duration and the need of NIV support were risk factors for unplanned reintubation after ATAAD.
