Background: and Purpose Symptomatic intracranial hemorrhage (sICH) following endovascular thrombectomy (EVT) is a severe complication associated with adverse functional outcomes and increased mortality rates. Currently, a reliable predictive model for sICH risk after EVT is lacking. Methods: This study used data from patients aged ≥20 years who underwent EVT for anterior circulation stroke from the nationwide Taiwan Registry of Endovascular Thrombectomy for Acute Ischemic Stroke (TREAT-AIS). A predictive model including factors associated with an increased risk of sICH after EVT was developed to differentiate between patients with and without sICH. This model was compared existing predictive models using nationwide registry data to evaluate its relative performance. Results: Of the 2,507 identified patients, 158 developed sICH after EVT. Factors such as diastolic blood pressure, Alberta Stroke Program Early CT Score, platelet count, glucose level, collateral score, and successful reperfusion were associated with the risk of sICH after EVT. The TREAT-AIS score demonstrated acceptable predictive accuracy (area under the curve [AUC]=0.694), with higher scores being associated with an increased risk of sICH (odds ratio=2.01 per score increase, 95% confidence interval=1.64–2.45, P<0.001). The discriminatory capacity of the score was similar in patients with symptom onset beyond 6 hours (AUC=0.705). Compared to existing models, the TREAT-AIS score consistently exhibited superior predictive accuracy, although this difference was marginal. Conclusions The TREAT-AIS score outperformed existing models, and demonstrated an acceptable discriminatory capacity for distinguishing patients according to sICH risk levels. However, the differences between models were only marginal. Further research incorporating periprocedural and postprocedural factors is required to improve the predictive accuracy.

Objective To make an epidemiological investigation on traditional Chinese medicine(TCM)dampness syndrome manifestations in the population at risk of cerebrovascular diseases in Guangdong area.Methods A cross-sectional study was conducted to analyze the clinical data related to the risk of cerebrovascular diseases in 330 Guangdong permanent residents.The diagnosis of dampness syndrome,quantitative scoring of dampness syndrome and rating of the risk of stroke were performed for the investigation of the distribution pattern of dampness syndrome and its influencing factors.Results(1)A total of 306(92.73%)study subjects were diagnosed as dampness syndrome.The percentage of dampness syndrome in the risk group was 93.82%(258/275),which was slightly higher than that of the healthy group(48/55,87.27%),but the difference was not statistically significant(χ2 = 2.91,P = 0.112).The quantitative score of dampness syndrome in the risk group was higher than that of the healthy group,and the difference was statistically significance(Z =-2.24,P = 0.025).(2)Among the study subjects at risk of cerebrovascular disease,evaluation time(χ2 = 26.11,P = 0.001),stroke risk grading(χ2= 8.85,P = 0.031),and history of stroke or transient ischemic attack(TIA)(χ2 = 9.28,P = 0.015)were the factors influencing the grading of dampness syndrome in the population at risk of cerebrovascular disease.Conclusion Dampness syndrome is the common TCM syndrome in the population of Guangdong area.The manifestations of dampness syndrome are more obvious in the population with risk factors of cerebrovascular disease,especially in the population at high risk of stroke,and in the population with a history of stroke or TIA.The assessment and intervention of dampness syndrome should be taken into account for future project of stroke prevention in Guangdong.

Objective:To understand the problems existing in the curriculum design of food hygiene and nutrition for undergraduates, and put forward countermeasures to improve the quality of talents cultivation and promote professional development.Methods:Self-made questionnaires were distributed by convenience sampling method, through online and offline ways, and the graduates' opinions on the curriculum design of their school. Quantitative data were analyzed by SPSS 26.0, and qualitative data were analyzed by NVivo 11.0.Results:A total of 258 valid questionnaires were recovered, and the average score of graduates' satisfaction with teaching quality was 2.42±1.02. Graduates had different opinions on the importance of special courses, and 150 students (58.14%) were satisfied with major courses. Some graduates thought the time of special courses was unreasonable and there were few major courses. Besides, 141 graduates (54.65%) were satisfied with the clinical probation in their graduation colleges. Although graduates believed that innovation ability was important, innovative education courses were scarce at present.Conclusions:Graduates are less satisfied with the setting of undergraduate curriculum in food hygiene and nutrition. It is suggested to optimize professional courses setting, improve experimental facilities and equipment, strengthen the management of practice bases, and pay attention to the cultivation of students' innovation and entrepreneurship ability.

Objective To investigate the associations of reproductive health indicators with lung function and chronic obstructive pulmonary disease(COPD)among women aged 40 years and above.Methods From Jul to Sep,2021,female subjects aged 40 years and above were randomly selected from the Shanghai Suburban Adult Cohort and Biobank for COPD screening.A questionnaire was used to obtain information on demographic characteristics and reproductive health indicators.Linear regression was used to analyze the effects of reproductive health indicators on forced vital capacity(FVC)and forced expiratory volume in the first second(FEV1).Logistic regression was also used to analyze the effects of reproductive health factors on FVC as a percentage of the predicted value(FVC%Pred)and FEV1%Pred as well as on COPD.Results A total of 1876 women aged 40 years and above were enrolled with mean age of(62.1±8.2)years old,among them,78.1%were menopausal,and 40.9%had been pregnant≥3 times.Multivariate analysis showed that FVC and FEV1 decreased in postmenopausal women,but menopause was not associated with a decrease in their percentage of predicted values.Pregnancies≥3 times was a risk factor for COPD(for 3 times,OR=4.92,95%CI:1.48-19.95,P<0.05;for≥4 times,OR=9.06,95%CI:2.32-41.57,P<0.01),while pregnancies of 2 times did not increase the risk of COPD.Conclusion In women aged 40 years and above,menopause is associated with poorer FVC and FEV1,and excessive pregnancy(≥3 times)is a risk factor for COPD.

In order to understand the infection and molecular genetic characteristics of goose astro-virus(GAstV)in Hotan,Xinjiang,visceral organs and swabs of dead goslings were collected asep-tically from three goose farms in Hotan,Yutian and Pashan counties,and GAstV was detected by RT-PCR.The positive samples were screened and identified in LMH cells,and the whole genome was sequenced,and the genetic characteristics of the isolates were analyzed.The results showed that the total positive rate of GAstV was 11.25％(65/578).Two strains of GAstV named as GAstV/XJHT-1 and GAstV/XJHT-2 were isolated and the lengths of their genome sequences were determined as 7 190 bp and 7 125 bp,respectively.Whole genome homology analysis showed that the homology of the two isolates with GAstV-1 and GAstV-2 was higher than 95％,and the homology with other sources(chicken,duck,and turkey)ranged from 54.1％to 61.5％.Genetic e-volution analysis showed that the genetic distance between GAstV isolates from Henan and Anhui was relatively close,suggesting that the isolated GAstV may be related to the introduction of gos-lings or goose eggs from these two places.The findings provide a basis for further development of vaccines or control products.

Klebsiella pneumoniae(KPn),as a conditioned pathogen that causes calf pneumonia,has caused serious harm to cattle industry,but the harm of Klebsiella pneumoniae to calves in Xin-jiang region is still unclear.In this study,to investigate the prevalence of KPn,its harm and some biological characteristics of pneumonia calves in Xinjiang,nasal swabs of pneumonia calves in some areas were collected aseptically,KPn isolation and identification were performed by routine meth-od,and 16S rDNA sequence evolutionary tree analysis was performed.The drug resistance was de-tected by K-B method,and a strain carrying multiple virulence was selected for mice median lethal dose test.The serotype,virulence gene and drug resistance gene of the strain were detected by PCR.The results showed that the detection rate of Klebsiella pneumoniae in nasal swabs of 218 pneumonia calves from Aksu,Changji and Yili regions of Xinjiang was as follows:14.68％(32/218),including 28.33％(17/60)in Aksu Prefecture,24.00％(6/25)in Changji Prefecture and 6.77％(9/133)in Yili Prefecture,they were divided into two serotypes,namely K1(7/32)and K5(5/32).A total of 13 KPn virulence genes were detected,mainly mrkD,ureA,wabG,uge and en-tB.LD50 was 2.38X 107cfu/mL.Drug susceptibility test and drug resistance gene detection showed that the isolated strain showed multiple drug resistance,and the resistance genes mainly carried blasHv and floR.16S rDNA sequence evolutionary tree results showed that the isolated strain had high homology with the isolates from Italy,Beijing and Shanghai of China.The detection rate of KPn in nasal swabs of pneumonia calves in Xinjiang region is high.The dominant serotypes are K1 and K5.The isolates carry a variety of virulence genes and have strong virulence.All of them are KPn strains producing ESBLs,suggesting that Klebsiella pneumoniae in Xinjiang region of China have a certain potential harm to calves.

Objective To investigate the effects of sufentanil on myocardial cells and renal function in rat models of non-stopping coronary artery bypass grafting.Methods SD rats were randomly divided into sham group(only thoracectomy without coronary artery ligation),model group(ischemia perfusion model was constructed),experimental-L group(ischemia perfusion model+0.5 μg·kg-1 sufentanil)and experimental-H group(ischemia perfusion model+1μg·kg-1 sufentanil).The mice were sacrificed 6 h after operation.The expressions of tumor necrosis factor-α(TNF-α),interleukin-1 β(IL-1 β)and interleukin-6(IL-6)in cardiomyocytes and renal cells were detected by enzyme-linked immunosorbent assay(ELISA).The expressions of apoptosis-related proteins in cardiomyocytes and renal cells were detected by Western blot.Serum renal function was detected with serum renal function kit.Results The expression levels of TNF-α in myocardial cells were(50.41±6.03),(136.61±21.73),(102.36±12.84)and(74.21±16.32)pg·mg-1 in sham group,model group,experimental-L group and experimental-H group,respectively;the expression levels of cysteinyl aspartate specific proteinase-3(Caspase-3)were 0.31±0.02,1.26±0.18,0.83±0.12 and 0.67±0.08,respectively;blood urea nitrogen(BUN)levels were(5.94±1.12),(20.04±5.36),(16.84±4.19)and(10.96±3.64)μmol·L-1,respectively;the expression levels of TNF-α in renal cells were(146.49±16.13),(1 023.82±34.69),(841.65±49.66)and(324.84±48.93)pg·mg-1,respectively;the expression levels of Caspase-3 in renal cells were 0.48±0.06,1.15±0.17,0.96±0.06 and 0.74±0.07,respectively.The difference between experimental-H group and sham group,model group and experimental-L group were statistically significant(all P＜0.05).Conclusion Sufentanil can significantly reduce the production of inflammatory factors and the expression of apoptotic proteins in rat cardiomyocytes,significantly improve the renal function of rats,and significantly reduce the production of inflammatory factors and the expression of apoptotic proteins in rat renal cells.

Objective: To investigate the epidemiology and hospitalization costs of pediatric community-acquired pneumonia (CAP) in Shanghai. Methods: A retrospective case summary was conducted on 63 614 hospitalized children with CAP in 59 public hospitals in Shanghai from January 2018 to December 2020. These children's medical records, including their basic information, diagnosis, procedures, and costs, were extracted. According to the medical institutions they were admitted, the patients were divided into the children's hospital group, the tertiary general hospital group and the secondary hospital group; according to the age, they were divided into <1 year old group, 1-<3 years old group, 3-<6 years old group, 6-<12 years old group and 12-18 years old group; according to the CAP severity, they were divided into severe pneumonia group and non-severe pneumonia group; according to whether an operation was conducted, the patients were divided into the operation group and the non-operation group. The epidemiological characteristics and hospitalization costs were compared among the groups. The χ² test or Wilcoxon rank sum test was used for the comparisons between two groups as appropriate, and the Kruskal-Wallis H test was conducted for comparisons among multiple groups. Results: A total of 63 614 hospitalized children with CAP were enrolled, including 34 243 males and 29 371 females. Their visiting age was 4 (2, 6) years. The length of stay was 6 (5, 8) days. There were 17 974 cases(28.3%) in the secondary hospital group, 35 331 cases (55.5%) in the tertiary general hospital group and 10 309 cases (16.2%) in the children's hospital group. Compared with the hospitalizations cases in 2018 (27 943), the cases in 2019 (29 009) increased by 3.8% (1 066/27 943), while sharply declined by 76.2% (21 281/27 943) in 2020 (6 662). There were significant differences in the proportion of patients from other provinces and severe pneumonia cases, and the hospitalization costs among the children's hospital, secondary hospital and tertiary general hospital (7 146 cases(69.3%) vs. 2 202 cases (12.3%) vs. 9 598 cases (27.2%), 6 929 cases (67.2%) vs. 2 270 cases (12.6%) vs. 9 397 cases (26.6%), 8 304 (6 261, 11 219) vs. 1 882 (1 304, 2 796) vs. 3 195 (2 364, 4 352) CNY, χ²=10 462.50, 9 702.26, 28 037.23, all P<0.001). The annual total hospitalization costs of pediatric CAP from 2018 to 2020 were 110 million CNY, 130 million CNY and 40 million CNY, respectively. And the cost for each hospitalization increased year by year, which was 2 940 (1 939, 4 438), 3 215 (2 126, 5 011) and 3 673 (2 274, 6 975) CNY, respectively. There were also significant differences in the hospitalization expenses in the different age groups of <1 year old, 1-<3 years old, 3-<6 years old, 6-<12 years old and 12-18 years old (5 941 (2 787, 9 247) vs. 2 793 (1 803, 4 336) vs. 3 013 (2 070, 4 329) vs. 3 473 (2 400, 5 097) vs. 4 290 (2 837, 7 314) CNY, χ²=3 462.39, P<0.001). The hospitalization cost of severe pneumonia was significantly higher than that of non-severe cases (5 076 (3 250, 8 364) vs. 2 685 (1 780, 3 843) CNY, Z=109.77, P<0.001). The cost of patients who received operation was significantly higher than that of whom did not (10 040 (4 583, 14 308) vs. 3 083 (2 025, 4 747) CNY, Z=44.46, P<0.001). Conclusions: The number of children hospitalized with CAP in Shanghai decreased significantly in 2020 was significantly lower than that in 2018 and 2019.The proportion of patients from other provinces and with severe pneumonia are mainly admitted in children's hospitals. Hospitalization costs are higher in children's hospitals, and also for children younger than 1 year old, severe cases and patients undergoing operations.
