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 investigate the effectiveness of TiRobot-assisted minimally invasive treatment for fragility fractures of the pelvis (FFP) in elderly patients. METHODS: A retrospective analysis was conducted on the clinical data of 176 patients with FFP who were admitted between July 2018 and July 2024 and met the selection criteria. Among them, 95 patients underwent TiRobot-assisted closed reduction and minimally invasive cannulated screw fixation (robot group), while 81 patients underwent traditional open reduction and plate screw fixation (control group). There was no significant difference in baseline data such as gender, age, fracture classification, disease duration, and preoperative visual analogue scale (VAS) pain scores between the two groups ( P>0.05). The following parameters were recorded and compared between the two groups, including operation time, intraoperative blood loss, intraoperative transfusion rate, volume of intraoperative blood transfusion, maximum incision length, hospital stay, maximum residual displacement, reduction quality, fracture healing time, incidence of complications, VAS scores, Majeed pelvic function scores, and functional grading. RESULTS: All surgeries in both groups successfully completed. The robot group exhibited significantly shorter operation time, reduced intraoperative blood loss, lower intraoperative transfusion rate, smaller volume of intraoperative blood transfusion, shorter maximum incision length, and shorter hospital stay compared to the control group ( P<0.05). In the robot group, a total of 14 INFIX internal fixation frames and 280 cannulated screws were implanted, among which 250 screws were rated as excellent, 17 as good, and 13 as poor, resulting in a screw placement excellent and good rate of 95.36%. Radiological review revealed that the excellent and good rate of reduction quality was in 91.58% (87/95) in the robot group and 81.48% (66/81) in the control group, with no significant difference in postoperative maximum residual fracture displacement or reduction quality between the two groups (P>0.05). All patients in both groups were followed up 12-66 months, with an average of 28.9 months, and there was no significant difference in follow-up time between the two groups ( P>0.05). The fracture healing time in the robot group was significantly shorter than that in the control group ( P<0.05). At last follow-up, both groups showed significant improvement in VAS scores compared to preoperative values ( P<0.05); the change values of VAS scores, Majeed scores, and the excellent and good rate of Majeed pelvic function were significantly higher in the robot group than in the control group ( P<0.05). Regarding postoperative complications, there was no significant difference between the two groups in terms of gait changes, secondary surgeries, heterotopic ossification, incision infections, walking difficulties, internal fixation failure, or mortality rates ( P>0.05); however, the incidence of delayed wound healing was significantly lower in the robot group than in the control group ( P<0.05). CONCLUSION TiRobot-assisted minimally invasive treatment of elderly FFP is superior to traditional open reduction and internal fixation in terms of surgical trauma control, postoperative rehabilitation speed, and functional recovery.

Objective To analyze the characteristics of time in range(TIR)and its relationship with oxidative stress(OS)and insulin resistance status(HOMA-IR)in patients with type 2 diabetes mellitus(T2DM)and sleep apnea-hypopnea syndrome(OSAHS).Methods According to apnea-hypopnea index(AHI),165 T2DM in patients were divided into simple T2DM group(AHI<5 times/h,n=43),T2DM combine OSAHS mild group(OSAHS-G,5≤AHI<15 times/h,n=51),T2DM combined OSAHS moderate group(OSAHS-M,15≤AHI≤30 times/h,n=40)and T2DM combine OSAHS severe group(OSAHS-S,AHI>30 times/h,n=31).TIR was calculated by dynamic blood glucose monitoring.Superoxide dismutase(SOD),glutathione peroxidase(GSH-Px)and other indexes were detected and analyzed.Results Compared with simple T2DM group,the levels of HOMA-IR,8-iso-PGF2a and Ox-LDL were higher in T2DM combined OSAHS-G,OSAHS-M or OSAHS-S group,while the levels of TIR,SOD and GSH-Px were lower(P<0.05).Pearson correlation analysis showed that TIR was positively correlated with the levels of SOD and GSH-Px(P<0.05 or P<0.01),and negatively correlated with the levels of 8-iso-PGF2a,Ox-LDL,HbA1c,HOMA-IR and the severity of OSAHS(P<0.01).Logistic regression analysis showed that TIR,SOD and GSH-Px were protective factors for severe OSAHS in T2DM patients,while 8-iso-PGE2a and Ox-LDL were the risk factors for severe OSAHS.Conclusions The glucose level fluctuates greatly in patients with T2DM and OSAHS.Insulin resistance and oxidative stress are factors that affect the normalization of TIR.

Objective:To explore the clinical efficacy of targeted interventional embolization therapy by a multidisciplinary team for the hemorrhagic shock caused by acute pelvic fracture or/and acetabular fracture.Methods:A retrospective study was conducted to analyze the data of 63 patients with hemorrhagic shock caused by pelvic fracture or/and acetabular fracture who had been admitted to Department of Orthopaedics, The Second Hospital of Shanxi Medical University from January 2015 to July 2022. There were 44 males and 19 females with an age of (39.6±15.6) years, and 23 pelvic fractures, 35 acetabular fractures, and 5 pelvic and acetabular fractures. The time from injury to targeted interventional embolization therapy was 2.67 (2.00, 3.33) hours. All the patients were treated with targeted interventional embolization therapy by a multidisciplinary team involving orthopedics, interventional medicine, general surgery, and urology. The shock index and lactate level within 12 hours after therapy, 24-hour urine output, and incidence of complications 3 weeks after therapy were recorded.Results:No bleeding was found again in the 63 patients after embolization. Within 12 hours after therapy, the shock index was ≤1.0, indicating the shock was corrected. Within 12 hours after targeted interventional embolization therapy, the shock index (0.70±0.46) and lactate value [(2.03±1.35) mmol/L] in the 63 patients were significantly lower than those before therapy [(1.76±0.56) and (4.53±1.74) mmol/L] ( P<0.05). The 24-hour urine output [(50.26±20.38) mL/h] was significantly higher than that before therapy [(21.56±1.27) mL/h] ( P<0.05). Two patients experienced poor blood circulation in the distal skin of the great toe, which was relieved after treatment with blood circulation promotion and anticoagulation. Three patients developed necrosis of the hip soft tissue, which was cured after multiple times of debridement and anti-infection treatments. One patient with severe injury died from multiple organ dysfunction. Conclusions:The targeted interventional embolization therapy can not only diagnose the bleeding location in patients with hemorrhagic shock caused by pelvic fracture or/and acetabular fracture, but also timely and accurately carry out hemostatic treatment to correct shock. Moreover, a multidisciplinary team can help patients avoid multiple surgeries and decrease their pain and financial loss.

Objective:To investigate the clinical and electrophysiological characteristics of patients with sudden unexpected death of epilepsy (SUDEP).Methods:Using "epilepsy" as the keyword, the relevant cases entered from October 2011 to March 2012 were searched in the database of the Electroencephalogram (EEG) Monitoring Center, Xijing Hospital, the Air Force Military Medical University. Telephone follow-up was conducted for all confirmed epilepsy patients, and for the death cases confirmed by telephone follow-up, the patients identified as consistent with SUDEP diagnosis were included in this study based on their past medical history, clinical data, death details, etc, and their clinical and neuroelectrophysiological characteristics were summarized and analyzed.Results:Among the 1 232 patients who underwent 24-hour video-EEG monitoring during the study period, 354 patients were successfully followed up by telephone interview, of whom 17 patients were died (4.8%), 12 individuals met the diagnosis of SUDEP (7 men, 5 women). The duration of the disease in 9 patients exceeded 10 years. Eight cases presented with focal-bilateral tonic clonic seizures. Nine patients were treated with anti-seizure drug monotherapy. All the 24-hour video EEG of 12 patients were abnormal. There were 8 occasions when the EEG occipital α background rhythm slowed down compared with the standard frequency of peers or was dominated by slow waves. Interictal epileptic discharge (IED) located in temporal lobe were found in 12 EEG records, of which 9 EEG records were found with frontal IED. One of the 12 cases received 24-hour video EEG twice within 6 years, and his EEG background rhythm was significantly slower and the IED region was expanded compared with the first EEG record. At the third year after reexamination of EEG, SUDEP developed in this patient.Conclusions:SUDEP patients have a long course of disease and bilateral tonic-clonic seizure. The interictal EEG shows occipital slow α activity and temporofrontal epileptiform discharges, which may increase the risk of SUDEP.

Objective:To investigate the relationship between central venous-arterial blood carbon dioxide partial pressure difference (Pcv-aCO 2) and left ventricular ejection fraction(LVEF) in acute myocardial infarction. Methods:Clinical data of patients with acute myocardial infarction admitted to the Intensive Care Unit of Fujian Provincial Hospital from November 2019 to October 2021 were retrospectively analyzed. LVEF was measured by bedside echocardiogram. The patients were divided into the normal LVEF group (LVEF ≥ 52%) and decreased LVEF group (LVEF < 52%) according to LVEF. The differences in general information and hemodynamic parameters between the two groups were compared. The normality of the above data was tested by the Jarque-Bera test. Correlation analysis of hemodynamic indices with LVEF was performed. Binary logistic regression was used to analyze the risk factors associated with the decrease in LVEF. The feasibility of diagnosing LVEF decline with Pcv-aCO 2 was assessed using receiver operating characteristic (ROC) curve. Results:Seventy-two patients with acute myocardial infarction were included for analysis, including 25 patients in the normal LVEF group and 47 patients in the decreased LVEF group. Pcv-aCO 2 was significantly higher in the decreased LVEF group than that in the normal LVEF group [(7.13±1.19) mmHg vs. (5.41±1.23) mmHg, P<0.01]. There was a negative correlation between LVEF and Pcv-aCO 2 ( rs= -0.740, P<0.01). The area under the ROC curve for Pcv-aCO 2 was 0.849 (95% CI: 0.758-0.939, P<0.01). The binary logistic regression analysis showed that Pcv-aCO 2 was an independent risk factor for decreased LVEF ( OR=2.251, 95% CI: 1.326-3.820). Conclusions:To a certain extent, the increase of Pcv-aCO 2 can predict the decrease of LVEF in acute myocardial infarction.

Objective:To investigate the relationship between the level of Apelin-13 and coronary artery lesion (CAL) in patients with Kawasaki disease (KD), and assess the predictive value of Apelin-13 for CAL in acute phase of KD.Methods:A total of 240 children with KD treated in Chengdu Women and Children′s Central Hospital from September 2017 to October 2019 were recruited, and were divided into KD with CAL (KD-CAL) group and KD without CAL (KD-NCAL) group.Thirty children with acute upper respiratory infection and 30 healthy children were recruited into the febrile control group and the healthy control group, respectively.Blood routine and serum levels of albumin, C-reactive protein (CRP), N-terminal pro-brain natriuretic peptide (NT-proBNP) and Apelin-13 were mea-sured in KD children prior to intravenous gamma globulin injection and after the diagnosis of children in the febrile control group and physical examination of children in the healthy control group.The clinical data of children in each group were compared, and the risk factors of KD complicated with CAL and the predictive value of Apelin-13 were determined by using receiver operating characteristic (ROC) curve and multiple Logistic regression analysis. Results:Apelin-13 and hemoglobin in children with KD were significantly decreased compared with those in the healthy control group and fever control group (all P<0.001). However, white blood cell(WBC) count, platelet count, CRP and NT-proBNP in KD group were significantly increased compared with those in the healthy control group and fever control group (all P<0.001). Serum albumin in KD children was significantly lower than that in the healthy control group ( P=0.004), and there was no difference when compared with the fever control group ( P=0.485). Apelin-13 and hemoglobin were significantly decreased in KD-CAL group compared with KD-NCAL group ( t=10.102, P<0.001; t=2.034, P=0.043), while NT-proBNP and CRP were significantly increased ( t=5.982, 3.728, all P<0.001). Multiple logistic regression analysis showed that Apelin-13 and NT-proBNP were independent predictors of CAL in KD.The ROC curve analysis showed that the cut-off value of Apelin-13 for predicting CAL was 2.99 μg/L, with an area under the curve (AUC) of 0.869 (95% CI: 0.820-0.909), sensitivity of 77.78% and specificity of 88.67%.While NT-proBNP cutoff value of 822 ng/L yielded sensitivity of 57.78% and specificity of 84.62% for predicting CAL with an AUC of 0.718(95% CI: 0.656-0.774). Conclusions:Apelin-13 plays a protective role in KD complicated with CAL, and could be used to predict CAL in the acute phase of KD.

Objective:To explore the relation of the radiochemical purity and in vivo imaging effect of 68Ga-1, 4, 7, 10-tetraazacyclododecane-1, 4, 7, 10-tetraacetic acid (DOTA)- D-phe1-Tyr3-Thr8-octreotide (TATE) injection. Methods:High performance liquid chromatography (HPLC) and thin-layer chromatography (TLC) methods were established to determine 68Ga-DOTATATE, 68Ga 3+ , 68Ga in colloidal form and 68Ga-DOTA- D-Phe1-Tyr3-Thr8-dethreonine-octreotide (heptapeptide) and to study the influence of precursor purity on radiochemical purity of labelled products. The uptake of 68Ga-DOTATATE injection with different radiochemical purities was investigated in nude mice bearing AR42J cells by microPET imaging and the tumor target/non-target (T/NT) value was calculated. One-way analysis of variance and Pearson correlation analysis were used to analyze the data. Results:The contents of 68Ga 3+ and 68Ga in colloidal form were not related with precursor purity ( r values: 0.385, 0.497, P values: 0.306, 0.137), while the content of 68Ga-DOTA-heptapeptide was positively related with the purity of DOTA-heptapeptide ( r=0.957, P<0.001). The radiochemical purities of 68Ga-DOTATATE injection were (87.0±2.3)%, (86.8±0.8)% and (94.0±3.1)% when the DOTATATE purities were 90.9%, 91.6% and 99.2%, respectively. The results of microPET imaging showed that the tumor uptake was positively related with the radiochemical purity of 68Ga-DOTATATE injection ( r=0.828, P<0.001), and the T/NT values of 68Ga-DOTATATE injection with radiochemical purities of 95.7%, 85.8%, 84.5% and 79.9% were 21.25±8.84, 8.50±1.51, 11.38±1.65 and 6.01±0.99, respectively ( F=11.48, P=0.001). Conclusion:The radiochemical purity of 68Ga-DOTATATE injection is impacted by the purity of labelled precursor and manufacturing processes and is related with the imaging effect in vivo.
