Background::Cerebrovascular disease (CVD) ranks among the foremost factors responsible for mortality on a global scale. The mortality patterns of CVDs and temporal trends in China need to be well-illustrated and updated.Methods::We collected mortality data on patients with CVD from Chinese Center for Disease Control and Prevention’s Disease Surveillance Points (CDC-DSP) system. The mortality of CVD in 2020 was described by age, sex, residence, and region. The temporal trend from 2013 to 2019 was evaluated using joinpoint regression, and estimated rates of decline were extrapolated until 2030 using time series models.Results::In 2019, the age-standardized mortality in China (ASMRC) per 100,000 individuals was 113.2. The ASMRC for males (137.7/10 5) and rural areas (123.0/10 5) were both higher when stratified by gender and urban/rural residence. The central region had the highest mortality (126.5/10 5), the western region had a slightly lower mortality (123.5/10 5), and the eastern region had the lowest mortality (97.3/10 5). The age-specific mortality showed an accelerated upward trend from aged 55-59 years, with maximum mortality observed in individuals over 85 years of age. The age-standardized mortality of CVD decreased by 2.43% (95% confidence interval, 1.02-3.81%) annually from 2013 to 2019. Notably, the age-specific mortality of CVD increased from 2013 to 2019 for the age group of over 85 years. In 2020, both the absolute number of CVD cases and the crude mortality of CVD have increased compared to their values in 2019. The estimated total deaths due to CVD were estimated to reach 2.3 million in 2025 and 2.4 million in 2030. Conclusion::The heightened focus on the burden of CVD among males, rural areas, the central and western of China, and individuals aged 75 years and above has emerged as a pivotal determinant in further decreasing mortalities, consequently presenting novel challenges to strategies for disease prevention and control.

Objective To explore the influence of processing depth of verb comprehension on the pro-cess of sensorimotor simulation of verbs and its automatization characteristics.Methods Thirty-six com-mon college students were selected,and required to complete verb semantic judgment tasks of Experi-ment 1 and non-semantic judgment tasks of Experiment 2.The changes in hand and foot action out-puts were also observed.Results In Experiment 1,in semantic judgment tasks,the reaction time of leg-related verbs was significantly shorter than for hand-related verbs(P=0.001),with no significant differences in true-false word judgment tasks.Moreover,in Experiment 2,no significant interaction ef-fect was found between verb types and action execution(P=0.199).Conclusion The sensorimotor simula-tion triggered by verb comprehension is modulated by processing of different depths,and individuals are more inclined to utilize sensorimotor simulation of verbs at higher levels of processing depth,non-automatically.

Objective:This study aims to explore the application value of the "liftoff" modular method in robot-assisted laparoscopic surgery for complex adrenal tumors.Methods:We retrospectively analyzed the clinical data of 15 patients with complex adrenal tumors treated at the General Hospital of Southern Theater Command from May 2022 to June 2023. The cohort comprised 5 males and 10 females with an average age of (47.6±7.8) years and a body mass index (BMI) of 26.5 (23.8-27.9) kg/m 2. Among the patients, 3 had a BMI ≥28 kg/m 2, 2 had diabetes, 6 had hypertension, and 1 had coronary heart disease. Preoperative endocrine hormone examination revealed abnormal blood catecholamines in 5 cases and abnormal blood cortisol in 2 cases. Ultrasound and CT scans indicated that 9 tumors were located on the left side and 6 on the right, with 4 cases showing tumor compression on adjacent large blood vessels or organs. The average tumor diameter was (7.61±2.79) cm, with 10 cases having a diameter ≥ 6 cm. All patients underwent laparoscopic adrenalectomy assisted by robots through the transperitoneal approach. The surgeries were performed in a lateral position under general anesthesia. The "liftoff" modular method was utilized to separate the treatment of adrenal tumors into lateral, medial, dorsal, cephalic, and adrenal renal plane sides. Tumors were appropriately manipulated during the operations to achieve a "liftoff" shape. Different modular dissociation steps were adopted based on the size and location of the left and right adrenal tumors. The left adrenal gland was dissected in the order of medial and dorsal, adrenal renal plane side, and lateral and cephalic sides, while the right adrenal gland was dissected in the order of lateral and dorsal, adrenal renal plane side, and medial and cephalic sides. Postoperative related indicators and follow-up status of patients were recorded and analyzed. Results:All 15 surgeries were successfully completed without any conversions to open adrenalectomy, with an average operation time of 118 (102-130) minutes and an average intraoperative blood loss of 102 (69-163) ml. The postoperative drainage time was 4 (3-5) days, and the postoperative hospital stay was 6 (4-7) days. The postoperative pathological diagnoses included 5 cases of pheochromocytoma, 3 cases of macronodular adrenal hyperplasia, 6 cases of adrenocortical adenoma, and 1 case of myelolipoma. Follow-up for 6-12 months after surgery showed good recovery and no recurrence.Conclusions:The application of the "liftoff" modular method in robot-assisted laparoscopic surgery for complex adrenal tumors is safe and feasible. It efficiently aids in tumor removal and holds significant clinical application value.

Objective:To explore the impact of early and late antibody-mediated rejection (AMR) on treatment options and allograft outcomes after kidney transplantation (KT).Methods:From January 2013 to December 2022, the study retrospectively enrolled 141 KT allograft recipients receiving allograft biopsy and diagnosed as AMR according to the Banff 2019 criteria. Recipients with a diagnosis of AMR within 30 days post-KT were classified into early AMR group (n=19) while the remainders assigned as late AMR group (n=122). The outcome endpoints included recipient survival rate, death-censored graft survival rate, follow-up estimated glomerular filtration rate (eGFR) and immunodominant donor-specific antibody (DSA) intensity. Wilcoxon's test was utilized for assessing the differences in eGFR and DSA intensity while Kaplan-Meier curve and Log-rank test were employed for evaluating graft survival impact. Treatment regimens for AMR were collected and categorized.Results:The median follow-up duration was 2.6(1.2, 5.2) year. No graft failure was noted in early AMR group while 44 recipients in late AMR group experienced graft failure, with 34 cases (77.2%) due to AMR progression. The 5-year death-censored graft survival rate was significantly better in early AMR group than that in late AMR group [100% vs 60.1%(50.5%, 71.6%), P=0.002]. The one-year change in eGFR for early AMR group was significantly superior to that of late AMR group [19.3(-2.6, 38.1) vs -3.3(-14.0, 5.4), P=0.001]. One-year mean fluorescent intensity (MFI) of early AMR group was 1 158(401.5, 3 126.5). It was significantly lower than that when diagnosed with early AMR [3 120.5(2 392.8, 9 340.0)] and one-year MFI of late AMR group [8 094(2 251.5, 13 560.5)] ( P=0.005, P<0.001). Early AMR group primarily received standard treatment (3/19, 15.8%) and regimens centered on rituximab and/or bortezomib (7/19, 43.8%). Late AMR group mainly received standard (16/122, 13.1%) or intensified regimens (9/122, 7.4%) and regimens focused upon rituximab and/or bortezomib (32/122, 26.2%) and MP monotherapy (21/122, 17.2%). Conclusion:The outcome for early AMR is significantly better than that for late AMR. For early AMR, early and robust immunosuppression is recommended. For late AMR, early detection and timely treatment are crucial and individualized strategies should be implemented.

Objective To establish an ultra-performance liquid chromatography-tandem mass spectrometry(UPLC-MS/MS)method for the detection of 34 prohibited and restricted pesticide residues in Atractylodes,and 21 batches of commercially available Atractylodes were detected to preliminarily investigate the pesticide residues in commercial Atractylodes.Methods The samples were extracted with pure acetonitrile,the extracts were purified by Waters-HLB 3cc(60 mg)solid phase extraction column,separated by Waters-C18 column,0.1%formic acid water(containing 10 mmol/L ammonium formate)and acetonitrile were used as mobile phases(gradient elution),and quantitatively analyzed by external standard method in multi-reaction monitoring positive ion mode according to the retention time.Results The linear relationship of each component was good in their respective concentration ranges,the correlation coefficients were all greater than 0.998 0.The limits of detection were within 0.8-4.0 μg/kg,and the limits of quantification were within 2.0-10.0 μg/kg.The average recovery rate was 74.1%-97.4%,and RSD was 0.6%-6.4%(n=9).Seven pesticide residues were found in 13 batches of 21 Atractylodes macrocephalus samples.Conclusion This method is simple to operate,accurate in quantification,has high recovery rate and good repeatability,and is suitable for the detection of multiple residues of prohibited and restricted pesticides in Atractylodes.

Objective To investigate the effect of diosmine on semen quality and sex hormone concentra-tion in patients with spermatovenous ligation.Methods Clinical data were retrospectively collected from January 2019 to January 2022 on patients with varicocele admitted to Department of Urology,General Hospital of Southern Theater Command,divided into a control group and a study group based on whether they had a history of Diosmine use after surgery.Clinical data from both groups were matched using propensity score matching.Sperm quality and sex hormone tests were then compared before surgery,three months after surgery and six months after surgery.Results There were 73 in the control group and 73 in the study group.Both groups were balanced in terms of age,BMI,seminal fluid volume and testosterone(P＞0.05).Sperm motility,forward motility and testosterone were all increased 3 and 6 months after surgery,and sperm malformations,sperm DNA fragment index,follicle stimulating hormone and luteinizing hormone were all reduced significantly(P＜0.05).The results were also better than those in the control group for total sperm motility,forward motility,testosterone,sperm DNA fragment index,follicle stimulating hormone and luteinizing hormone(P＜0.05).Conclusions Diosmine can help to restore semen quality and improve sex hormone concentration in patients with varicocele after Laparoscopic varicocelectomy.

Objective:To investigate the relationship between the cerebral small vascular disease (CSVD) total burden and the imaging markers and the degree of unilateral middle cerebral artery (MCA) stenosis.Methods:The study was a cross-sectional study. Clinical and imaging data of patients with chronic unilateral MCA stenosis who underwent multimodal MRI from October 2015 to January 2019 in the First Medical Center of PLA General Hospital were retrospectively analyzed. A total of 261 patients were included, 187 males and 74 females. According to the degree of MCA stenosis, the patients were divided into 102 cases in severe stenosis-occlusion group (stenosis degree ≥70%) and 159 cases in mild-moderate stenosis group (stenosis degree <70%). CSVD imaging marker scores (including white matter hyperintensity, perivascular space, cerebral microbleed, and lacune of presumed vascular origin) were assessed according to the ?standards for reporting vascular changes on neuroimaging 1 in the 2 groups, and the CSVD total burden score was calculated. Mann-Whitney U test was used to compare the indicators between the two groups, and the CSVD total burden score and imaging marker scores were ultimately included in a multifactorial binary logistic regression to assess the association of CSVD imaging markers with severe stenosis-occlusion of the MCA after adjusting for vascular risk factors (age, gender, drinking, smoking, hypertension, hyperlipidemia, atrial fibrillation and coronary heart disease). Results:There were significant differences in the CSVD total burden, centrum semiovale perivascular space and lacune of presumed vascular origin score between the mild-to-moderate stenosis group and the severe stenosis-occlusion group (all P<0.05), and none of the differences in the remaining imaging marker scores were statistically significant (all P>0.05). Multivariate binary logistics regression analysis showed CSVD total burden score ( OR=1.300, 95% CI 1.047-1.613, P=0.017), centrum semiovale perivascular space score ( OR=2.099, 95% CI 1.540-2.860, P<0.001) and lacune of presumed vascular origin score ( OR=2.609, 95% CI 1.294-5.261, P=0.007) were independent associated with severe stenosis-occlusion of MCA. Conclusion:The higher CSVD total burden score, centrum semiovale perivascular space score and lacune of presumed vascular origin score are associated with severe stenosis-occlusion of MCA.

Objective:To compare the efficacy of conventional open ankle fusion and three dimensional(3D) printed guide plate assisted arthroscopic ankle fusion.Methods:A retrospective cohort study was performed on 256 patients with advanced traumatic ankle arthritis, who were admitted to the Department of Orthopaedics, Shanghai Sixth People′s Hospital Affiliated to Shanghai Jiao Tong University School of Medicine from May 2018 to February 2023 and underwent ankle fusion procedures. The study cohort comprised 119 males and 137 females, with an age of (59.6±9.5) years (range: 37 to 83 years). Among them, 175 cases underwent internal fixation with plates and screws (58 cases through the combined medial and lateral approach, and 117 cases through the simple lateral approach), 48 cases underwent internal fixation with screws through the anterior approach (conventional open group), and 33 cases underwent minimally invasive arthroscopic ankle fusion assisted by 3D printed guide plate (3D printed guide plate arthroscopy group). Propensity score matching was employed to achieve a 1∶1 match(caliper value=0.02) between the baseline characteristics of patients in the 3D printed guide plate arthroscopy group and the conventional open group. Perioperative and follow-up data between the two groups were compared using the t-test, Mann-Whitney U test, Wilcoxon signed rank test, χ2 test or corrected χ2 test as appropriate. Results:Matching was successfully achieved with 20 cases in both the 3D printed guide plate arthroscopy group and the conventional open group, and there were no statistically significant differences in baseline characteristics between the two groups (all P>0.05). The operation time in the 3D printed guide plate arthroscopy group was significantly longer than that in the conventional open group ((88.9±5.6) minutes vs. (77.9±11.7) minutes; t=-2.392, P=0.022), while the frequency of intraoperative fluoroscopies ((1.7±0.8) times vs. (5.2±1.2) times; t=10.604, P<0.01) and length of hospitalization ((5.5±0.9) days vs. (6.4±1.5) days; t=2.480, P=0.018) were significantly lower in the 3D printed guide plate arthroscopy group compared to the conventional open group. The fusion rate was 95.0% (19/20) in the 3D printed guide plate arthroscopy group and 85.0% (17/20) in the conventional open group, with no statistically significant difference between the two groups ( χ2=0.278, P=0.598). The fusion time was (12.1±2.0) weeks in the conventional open group and (11.1±1.7) weeks in the 3D printed guide plate arthroscopy group, with no statistically significant difference between the two groups ( t=1.607, P=0.116). At the final follow-up, the American Orthopedic Foot and Ankle Society ankle hindfoot scale was (72.6±5.5)points in the 3D printed guide plate arthroscopy group and (70.5±5.8)points in the conventional open group, with no statistically significant difference between the two groups ( t=-1.003, P=0.322). The pain visual analogue score of the 3D printed guide plate arthroscopy group was ( M(IQR)) 1.50 (1.00) points, lower than that of the conventional open group by 3.00 (1.00) points, with statistically significant differences ( Z=-3.937, P<0.01). There was no significant difference in complication rate between the conventional open group and the 3D printed guide plate arthroscopy group (25.0%(5/20) vs. 5.0%(1/20), χ2=1.765， P=0.184). Conclusion:3D printed guide plate assisted arthroscopic ankle fusion exhibited several advantages, including reduced frequency of fluoroscopies, alleviation of postoperative pain, and decreased complications and length of hospitalization.

Objective To explore the role of sulodexide(SDX)in neointimal hyperplasia of arteriovenous fistulas(AVFs)in chronic kidney disease(CKD)rats and its possible mechanism.Methods A total of 18 male rats(weighing 300±50 g)were randomly and equally divided into AVF group,CKD+AVF group(CKD induction followed by AVF surgery and then gavaged with normal saline for 2 months),and CKD+AVF+SDX group[treated as in the CKD+AVF group but with 8 mg/(kg·d)SDX gavage].HE staining was used to observe the degree of neointimal hyperplasia.The expression of Hippo pathway related molecules,Yes-associated protein(YAP),pYAP and connective tissue growth factor(CTGF,YAP downstream target protein,one of mesenchymal marker)was detected by immunofluorescence assay.After human umbilical vein cell fusion EAHy926 cells were treated with 0,2.5,5,10,20 or 40 μg/mL SDX for 24 h,and with 2.5 μg/mL SDXfor24,48 or 72 h,respectively,CCK-8 assay was used to measure cell survival rate.Moreover,the serum sample from CKD rat was used to treat EAHy926 cells,and then the cells were treated with SDX or YAP inhibitor verteporfin.The expression levels of YAP,pYAP,CTGF and endothelial cell marker CD31 were detected by Western blotting.Results HE staining and immunofluorescence assay showed that CKD rats had serious neointimal hyperplasia in AVFs(P＜0.05),and slightly lower expression of pYAP and enhanced expression of CTGF(P＜0.05)when compared with the rats of the AVF group.While,SDX treatment alleviated the neointimal hyperplasia of AVFs,enhanced the expression of pYAP and reduced the expression of CTGF(P＜0.05).CCK-8 assay showed that cell survival rate was decreased significantly in a dose-and time-dependent manner after SDX treatment(P＜0.05).Western blotting revealed that SDX increased the expression of pYAP and CD31 while inhibited the expression of CTGF in EAHy926 cells(P＜0.05),which was consistent with the effect of verteporfin treatment.Conclusion SDX can block YAP activation caused by CKD and attenuate neointimal hyperplasia in AVFs.
