ABSTRACT
To investigate the status and epidemiological characteristics of respiratory pathogens infections in children with influenza-like illnesses (ILI) in Beijing Children's Hospital from 2022 to 2023. A dual amplification technique was used to detect nucleic acids of seven common respiratory pathogens, including influenza A virus (Flu A), influenza B virus (Flu B), mycoplasma pneumoniae (MP), respiratory syncytial virus (RSV), parainfluenza virus (PIV), adenovirus (ADV), and Chlamydia pneumoniae (CP), in outpatient and inpatient children (aged 0-18 years) with influenza-like symptoms who sought medical care at Beijing Children's Hospital, from January 2022 to March 2023. A total of 43 663 children were included in the study, of which 27 903 tested positive for respiratory pathogens with a total detection rate of 63.91%. Flu A had the highest detection rate of 69.93% (27 332/39 084), followed by MP about 13.22% (380/2 875). The total detection rate of RSV, PIV and ADV was 7.69% (131/1 704). Flu B had a detection rate of 0.16% (64/39 084). No CP was detected in this study. A total of 7 cases of dual infections were detected, with a detection rate of 0.41% (7/1 704). The Chi-square test was used to analyze the differences in detection rates of pathogens among different genders, age groups, and different seasons. Among the seven pathogens, only Flu A had statistically significant differences in gender (χ2=16.712, P<0.001). The detection rates of Flu A and MP showed an increasing trend with age (both P trend<0.001), while the detection rates of RSV and PIV showed a decreasing trend with age (both P trend<0.001). Flu A had its epidemic peak in winter and spring, with detection rates of 61.30% (3 907/6 374) and 77.47% (23 207/29 958) respectively; MP and PIV had higher detection rates in autumn (25.14% and 7.64% respectively); RSV showed a relatively higher detection rate in winter (8.69%); Flu B and ADV had lower detection rates throughout the study period (0.16% and 1.17% respectively). In conclusion, children with ILI in 2022-2023 were mainly infected with a single respiratory pathogen, and occasionally dual pathogen infections were observed. Among them, the detection rate of Flu A was the highest, and only Flu A showed a gender difference in detection rate. As the age of the children patients increased, the detection rate of Flu A and MP showed an increasing trend, while RSV and PIV showed a decreasing trend. The prevalence of Flu A, Flu B, MP, PIV, and RSV were seasonal.

Since 1986, the WHO has held ten global health promotion conferences covering various health promotion issues and sustainable development worldwide. These sessions have formed a series of consensus and actions that guide promoting health globally. This study analyzed the declarations, reports, and news materials from the ten conferences that studied health promotion action areas, focal topics, actor networks, partnership relationships, and other significant outcomes. It also explored how these conferences contributed to the construction and advancement of global health promotion consensus and actions. The first Global Conference on Health Promotion identified the concept of health promotion and five key action areas, laying the foundation for subsequent conferences and health promotion actions. Over the years, the ten conferences continuously expanded the essence of health promotion, developed partnership relationships, formulated public health promotion policies, and called for health promotion actions. This process culminated in the formation of global consensus and collective actions. The latter conferences have gained significant attention and influence. The conferences offer valuable insights for future global health promotion endeavors and provide global perspectives and pathways for the development of Healthy China.

Objective: To describe the current status and trends in the outcomes and care practices of extremely preterm infants at 22-25 weeks' gestation age from the Chinese Neonatal Network (CHNN) from 2019 to 2021. Methods: This cross-sectional study used data from the CHNN cohort of very preterm infants. All 963 extremely preterm infants with gestational age between 22-25 weeks who were admitted to neonatal intensive care units (NICU) of the CHNN from 2019 to 2021 were included. Infants admitted after 24 hours of life or transferred to non-CHNN hospitals were excluded. Perinatal care practices, survival rates, incidences of major morbidities, and NICU treatments were described according to different gestational age groups and admission years. Comparison among gestational age groups was conducted using χ2 and Kruskal-Wallis tests. Trends by year were evaluated by Cochran-Armitage and Jonckheere-Terpstra tests for trend. Results: Of the 963 extremely preterm infants enrolled, 588 extremely preterm infants (61.1%) were male. The gestational age was 25.0 (24.4, 25.6) weeks, with 29 extremely preterm infants (3.0%), 88 extremely preterm infants (9.1%), 264 extremely preterm infants (27.4%), and 582 extremely preterm infants (60.4%) at 22, 23, 24, and 25 weeks of gestation age, respectively. The birth weight was 770 (680, 840) g. From 2019 to 2021, the number of extremely preterm infants increased each year (285, 312, and 366 extremely preterm infants, respectively). Antenatal steroids and magnesium sulfate were administered to 67.7% (615/908) and 51.1% (453/886) mothers of extremely preterm infants. In the delivery room, 20.8% (200/963) and 69.5% (669/963) extremely preterm infants received noninvasive positive end-expiratory pressure support and endotracheal intubation. Delayed cord clamping and cord milking were performed in 19.0% (149/784) and 30.4% (241/794) extremely preterm infants. From 2019 to 2021, there were significant increases in the usage of antenatal steroids, antenatal magnesium sulfate, and delivery room noninvasive positive-end expiratory pressure support (all P<0.05). Overall, 349 extremely preterm infants (36.2%) did not receive complete care, 392 extremely preterm infants (40.7%) received complete care and survived to discharge, and 222 extremely preterm infants (23.1%) received complete care but died in hospital. The survival rates for extremely preterm infants at 22, 23, 24 and 25 weeks of gestation age were 10.3% (3/29), 23.9% (21/88), 33.0% (87/264) and 48.3% (281/582), respectively. From 2019 to 2021, there were no statistically significant trends in complete care, survival, and mortality rates (all P>0.05). Only 11.5% (45/392) extremely preterm infants survived without major morbidities. Moderate to severe bronchopulmonary dysplasia (67.3% (264/392)) and severe retinopathy of prematurity (61.5% (241/392)) were the most common morbidities among survivors. The incidences of severe intraventricular hemorrhage or periventricular leukomalacia, necrotizing enterocolitis, and sepsis were 15.3% (60/392), 5.9% (23/392) and 19.1% (75/392), respectively. Overall, 83.7% (328/392) survivors received invasive ventilation during hospitalization, with a duration of 22 (10, 42) days. The hospital stay for survivors was 97 (86, 116) days. Conclusions: With the increasing number of extremely preterm infants at 22-25 weeks' gestation admitted to CHNN NICU, the survival rate remained low, especially the rate of survival without major morbidities. Further quality improvement initiatives are needed to facilitate the implementation of evidence-based care practices.

Objective: To investigate a SARS-CoV-2 epidemic reported in Rongcheng City, Weihai, Shandong Province. Methods: The SARS-CoV-2 nucleic acid positive patients and their close contacts were investigated, and the whole genome sequencing and genetic evolution analysis of 9 variant viruses were carried out. An infection source investigation and analysis were carried out from two sources of home and abroad, and three aspects of human, material and environment. Results: A total of 15 asymptomatic infections were reported in this epidemic, including 13 cases as employees of workshop of aquatic products processing company, with an infection rate of 21.67% (13/60). Two cases were infected people's neighbors in the same village (conjugal relation). The first six positive persons were processing workers engaged in the first process of removing squid viscera in the workshop of the company. The nucleic acid Ct value of the first time were concentrated between 15 and 29, suggesting that the virus load was high, which was suspected to be caused by one-time homologous exposure. The whole genome sequence of 9 SARS-CoV-2 strains was highly homologous, belonging to VOC/Gamma (Lineage P.1.15). No highly homologous sequences were found from previous native and imported cases in China. It was highly homologous with the six virus sequences sampled from May 5 to 26, 2021 uploaded by Chile. The infection source investigation showed that the company had used the squid raw materials captured in the ocean near Chile and Argentina from May to June 2021 over the last 14 days. Many samples of raw materials, products and their outer packages in the inventory were tested positive for nucleic acid. Conclusion: This epidemic is the first local epidemic caused by the VOC/Gamma of SARS-CoV-2 in China. It is speculated that the VOC/Gamma, which was prevalent in South America from May to June 2021, could be imported into China through frozen squid.

Objective: To develop a suitable scale for assessing the public health safety literacy in residents in China. Methods: The initial scale of Chinese public health safety literacy was developed through theoretical conceptualization, item pooling, field verifying and item inclusion and exclusion. Then the initial scale was converted into an electronic questionnaire. A total of 2 809 residents from 4 provinces were randomly selected for field testing. Classical test theory (CTT) and item response theory (IRT) were used for item reduction. SPSS 23.0 was used for exploratory factor analysis (EFA) and unidimensional testing. Package R 4.1.1 ltm and mirt were used for the analysis of the psychometric properties of items and generate the ICC, IIC and TIF. Results: The initial scale had 30 items (B1-B30), and the test took 9.8 s to complete one item averagely. According to the CTT, B2 was deleted due to coefficient of total correlation (CITC) <0.3 and the item-dimension correlation coefficient (IDCC) <0.4. B23 was deleted due to CITC<0.3, IDCC<0.4 and difficulty index (W) <0.2. B30 was deleted due to CITC<0.3 and W<0.2. The total Cronbach's α of the scale was 0.923 after deletion. EFA indicated that 14 items should be deleted due to lower factor loadings <0.7. EFA was conducted for remaining 13 items and 2 common factors were extracted, the factor loadings of all items were >0.7, the accumulated variance contribution of the 2 common factors was 63.361%, and the total Cronbach's α was 0.891, showing unidimensionality, IRT was used to test the remaining items. B14 and B20 were deleted due to discrimination coefficient (a) <0.3, difficulty threshold coefficient (b) ∉[-3,3], the small amount of information and the flat, crowded, non-monotonic ICC, and IIC. Finally, the Cronbach's α of the 11-itemed scale was 0.936 with TLI=0.97, CFI=0.99, and RMSEA=0.03. Conclusion: The final scale has good reliability, validity, discrimination, difficulty level and feasibility, and can be applied for the rapid assessment of public health safety literacy in China.

Objective: To evaluate the clinical value of aspirin as a prophylactic for transplant renal artery stenosis (TRAS). Methods: From January 2017 to November 2019, clinical data of 307 patients who had undergone renal transplant in Zhengzhou University People's Hospital were collected. Patients were divided into two groups: the treatment group (124 recipients who had taken oral aspirin 100 mg/d after transplant) and the control group (183 recipients who had not taken aspirin after transplant). The general data, incidence of initially diagnosed and confirmed TRAS, type of renal artery anastomosis vessels, duration of stenosis, location of stenosis, and complications were compared between the two groups. The treatment group was further divided into two subgroups, the early group (92 recipients) and the delayed group (32 recipients), according to the time of starting aspirin after operation. Subgroup analysis was performed. Results: Among all 307 patients included, there were 241 males and 66 females, aged 19-64 years. There were no statistical difference between the treatment and control groups in terms of gender, age, comorbidities, number of arterial vessels, type of graft, and acute rejection all P>0.05. Among 46 initially diagnosed TRAS patients, 13 (10.5%) and 33 (18.0%) cases were in the treatment and control group respectively, with no statistically significant difference in stenosis rate (P>0.05). The number of confirmed TRAS patients was 1 (0.8%) and 24 (13.1%) in the treatment and control group respectively, with statistically significant difference in stenosis rate (P<0.001). The proportion of patients with bleeding disorders in the treatment group was slightly higher than that in the control group (13.7% vs 8.7%), and the proportion of infarct diseases was slightly lower than that in the control group (1.6% vs 4.9%). But there was no significant difference in aspirin-related complications between the two groups (P>0.05). Subgroup analysis showed that there was no significant difference in initially diagnosed and confirmed TRAS and aspirin-related complications between the early group and the delayed group (all P>0.05). Conclusions: Oral low-dose aspirin after kidney transplantation can effectively reduce the incidence of TRAS, without increasing the risk of aspirin-related complications.

Objective: To develop a measurement scale for the public health and safety literacy of university freshmen. Methods: Item pooling was conducted through literature review and in-depth interview with public health experts, and a nominal group was organized to develop the initial items to form the questionnaire. A total of 250 freshmen were randomly selected to complete the questionnaire, and the assessment of psychometric properties were performed to carry out item reduction by using classical test theory and item response theory. Exploratory factor analysis method (EFA) was employed to calculate the item-factor loadings. The data collected from another 318 freshmen were analyzed using confirmatory factor analysis method (CFA). Results: The scale contained 3 dimensions and 9 items with all content validity index ≥0.8. The difficulty coefficient of 9 items was 1.18-2.43. The discriminative validity analysis showed that the difficulty index was 0.41-0.78, and the discrimination index was 0.38-0.64. Each of the remaining items had a statistically significant difference in the score value between the top 27% and lowest 27% of respondents (t>3, P<0.05). The item's Cronbach's α was 0.72-0.77, corrected item-total correlation was 0.33-0.60 and the overall α of the scale was 0.77. EFA indicated all item-factor loading were higher than 0.680, and the accumulated variance contribution of the 3 factors was 62.484%. Results of CFA showed that the overall fitness index of the model reached the fitness standard except for the χ2 value. There was no statistical significance in the total score of the scale and the scores of each item among groups with different demographic characteristics (P>0.05). Conclusions: The newly developed public health safety literacy scale had a good reliability,validity,stability and item constancy.It can be used in measurement of the public health and safety literacy of university freshmen.

ABSTRACT
Objective: To explore the feasibility and safety of minimally invasive surfactant administration (MISA) in preterm neonates with respiratory distress syndrome (NRDS). Methods: In this multicenter prospective randomized controlled trial, 92 preterm infants with gestation age ≤30 weeks and diagnosed with NRDS were enrolled in 8 level â ¢ neonatal intensive care units (NICU) in Beijing-Tianjin-Hebei Region from 1(st) July 2017 to 31(st) December 2018. They were randomly assigned to minimally invasive surfactant administration (MISA) group or endotracheal intubation surfactant administration (EISA) group according to random number generated by computer. Infants in both groups received calf pulmonary surfactant preparation at a dose of 70-100 mg/kg. The data of demography, perinatal situation, medication administration, complications, clinical outcomes in the two groups were compared with Chi-square test, Student's t-test, Mann-Whitney U test or Fisher's exact test. Results: Among the 92 preterm infants, 53 were males, 39 were females; 47 were in the MISA group (25 males), and 45 were in the EISA group (28 males). The gestational age and birth weight were (29.5±1.2) weeks and (1 271±242) g in all patients, (29.5±1.4) weeks and (1 285±256) g in the MISA group, and (29.6±0.9) weeks and (1 255±227) g in the EISA group. The duration of surfactant infusion and the length of whole procedure in the MISA group were significantly longer than that in the EISA group (60 (18, 270) s vs. 50 (30, 60) s, Z=3.009, P=0.003; 90 (60, 300) s vs. 60 (44, 270) s, Z=3.365, P=0.001). For the outcomes, the incidence of hemodynamically significant patent ductus arteriosus (hsPDA) and bronchopulmonary dysplasia (BPD) were lower in the MISA group than in the EISA group (36% (17/47) vs. 67% (30/45), χ(2)=8.556, P=0.003; 26% (12/47) vs. 47% (21/45), χ(2)=4.464, P=0.035). Conclusions: Minimally invasive surfactant administration is applicable in preterm infants ≤30 weeks gestational age with NRDS. Although the length of whole procedure is longer than route endotracheal administration, the benefit of decreasing the incidences of hsPDA and BPD outweighs this demerit.

OBJECTIVE: Recently, long non-coding RNAs (lncRNAs) have been extensively studied for their role in tumor progression. This work explored the role of lncRNA DLX6-AS1 in mediating the development of ovarian cancer (OC). PATIENTS AND METHODS: DLX6-AS1 expression was detected by Real Time-quantitative Polymerase Chain Reaction (RT-qPCR) in OC tissues. Moreover, wound healing assay and transwell assay were performed to detect the effect of DLX6-AS1 on the metastasis of OC. Furthermore, the underlying mechanism of DLX6-AS1 in mediating the progression of OC was explored through the Dual-Luciferase reporter gene assay and RNA immunoprecipitation assay (RIP). RESULTS: DLX6-AS1 expression was higher in OC samples than that in the adjacent ones. Moreover, cell migration and invasion were suppressed after DLX6-AS1 knockdown in vitro. Conversely, cell migration and invasion were promoted by overexpressed DLX6-AS1. Moreover, the expression of microRNA-613 (miR-613) was upregulated via knockdown of DLX6-AS1, but was downregulated after overexpression of DLX6-AS1. Furthermore, the Luciferase reporter gene assay and RIP assay showed that miR-613 was a direct target of MIAT in DLX6-AS1 in OC tissues. CONCLUSIONS: DLX6-AS1 could enhance migration and invasion of OC cells via targeting miR-613, which might serve as a potential therapeutic target in OC.
ABSTRACT
Objective: To investigate the role of piperine on the transformation of endothelial cells into fibroblasts. Methods: Cultured human umbilical vein endothelial cells (HUVECs, 4-6 passage) were used for the main experiments. The transformation models of endothelial cells into fibroblasts were induced by transforming growth factor ß (TGF-ß) stimulation. HUVECs were divided into 6 groups: control group, TGF-ß group and 4 groups treated with various concentrations of piperine (1, 5, 10, 20 µmol/L). CKK-8 was used to detect cell proliferation. The CD31/α-smooth muscle actin (α-SMA) expression level was detected by fluorescent staining. The vascular endothelial cadherin (VE-cadherin)/vimentin expression was detected by immunofluorescence staining. RT-PCR was used detect the mRNA expressions of transformation markers. Western blot was used to detect the protein expression of snail and twist. Results: TGF-ß increased HUVECs proliferation (P<0.05), which could be significantly inhibited by 10 and 20 µmol/L of piperine, but not by 1 and 5 µmol/L of piperine. Immunofluorescence results demonstrated that TGF-ß increased HUVECs transformation to fibroblasts as shown by downregulated expression of endothelial markers CD31, VE-cadherin, and upregulated expression of α-SMA and vimentin, again, these effects could be attenuated by 10 and 20 µmol/L piperine. The expression levels of collagen type â and type â ¢ were significantly higher in TGF-ß group than in control group (P<0.05), significantly lower in TGF-ß+10 µmol/L piperine group and TGF-ß+20 µmol/L piperine group than in TGF-ß group (P<0.05).In addition, RT-PCR results showed that TGF-ß increased mRNA expression of transformation markers (snail1, snail2, twist1, twist2), while 10 and 20 µmol/L of piperine could significantly downregulated the mRNA expressions of these markers. The protein expression levels of snail and twist were significantly higher in TGF-ß group than in control group (both P<0.05), which was significantly lower in TGF-ß+20 µmol/L piperine group than in TGF-ß group (both P<0.05). Conclusions: Piperine can inhibit the transformation of endothelial cells into fibroblasts. This effect might be viewed as one of the potential mechanisms of reduced myocardial fibrosis post piperine treatment.

Streptococcus is a major mastitis-causing pathogen in dairy cows. To investigate the prevalence, antimicrobial resistance and virulence gene of Streptococcus in mastitic milk, a total of 735 mastitic raw milk samples from dairy cows in 11 provinces of China were collected and tested. Antimicrobial resistance of Streptococcus isolates was determined by disc diffusion against 8 classes 29 antimicrobial agents, and Streptococcus resistant genes and virulence genes were determined by PCR and agarose gel electrophoresis. A total of 64 (8.71%) isolates of Streptococcus were isolated and identified using biochemical profiling, including 22 isolates of Streptococcus agalactiae, 13 isolates of Streptococcus dysgalactiae, and 29 isolates of Streptococcus uberis. Out of 64 resistant Streptococcus isolates, all isolates (100%) were resistant to 3 or more antimicrobials. The most frequency (nâ¯=â¯18, 28.12%) of the isolates were multi-resistant to 5-7 antimicrobials and the highest multi-resistant number was 29 (nâ¯=â¯1, 1.56%). Streptococcus isolates had the highest resistance rate to tetracycline (98.44%) and oxacillin (98.44%), followed by penicillin G (96.88%) and doxycycline (96.88%), and the lowest resistance was observed with respect to ciprofloxacin (1.56%). A total of 16 antimicrobials resistance genes with 25 combination patterns were detected in the isolates. The gene combination of Sul1/Sul2/Sul3 + gyrA/parC + cat1/cat2 was the most common pattern (12.5%). The correlation between resistant phenotypes and resistance genes in Streptococcs was 35.87%. A total of 7 virulence genes were detected and 59 (92.19%) isolates harbored at least one gene. Twenty-four classes of gene patterns were found in the isolates and the patterns of bca (9.38%) and cfb (9.38%) were the most prevalent form. In conclusion, the issue of drug resistance of Streptococcus is still a great concern in cattle health in China.

OBJECTIVE: To explore the role of LINC00963 in the pathogenesis of hepatocellular carcinoma and its underlying mechanisms. PATIENTS AND METHODS: The expression level of LINC00963 in 48 cases of hepatocellular carcinoma (HCC) tissues and paracancerous tissues were detected by quantitative Real-time (qRT-PCR). Survival analysis was carried out based on the expression level of LINC00963. The association between the expression level of LINC00963 and clinical characteristics of these subjects was analyzed by x2-test. The proliferation and cell cycle of HCC cells after transfection of LINC00963 overexpression plasmids were evaluated by cell counting kit-8 (CCK-8) assay and flow cytometry, respectively. RESULTS: The expression level of LINC00963 in HCC tissues was remarkably higher than that in paracancerous tissues, indicating a potential diagnostic significance of LINC00963. The progression-free -with the tumor size and TNM stage, but not with age, gender, histological type and lymph node metastasis. Overexpression of LINC00963 significantly enhanced the proliferation ability of HepG2 and HCC cells and prolonged their G0/G1 phase. Furthermore, the PI3K/AKT expression was increased after overexpression of LINC00963, while AKT siRNA effectively reversed the prolonged G0/G1 phase caused by LINC00963 overexpression. CONCLUSIONS: Our data revealed that LINC00963 was upregulated in HCC, which significantly extended the G0/G1 phase of HCC cells by activating PI3K/AKT pathway and promoting the proliferative ability of HCC cells. LINC00963 may be involved in the HCC development.

OBJECTIVE: Isolated systolic hypertension (ISH) is the most important risk factor for ischemic stroke. Genetic variants influencing hypertension can also be risk factors for ischemic stroke. Here, we examined the how single nucleotide polymorphisms (SNPs) associated with blood pressure impact the risk for ischemic stroke. PATIENTS AND METHODS: We selected 300 ischemic stroke patients and 300 controls. Then, we genotyped three single nucleotide polymorphisms associated with systolic hypertension in both groups. RESULTS: Logistic regression analysis showed that the rs11099098 genotype was associated with a significantly decreased risk of IS (Dominant model: OR = 0.55, 95% CI = 0.37-0.82, p = 0.003). Two other SNPs, rs880315 and rs11072518, showed a trend towards association with stroke risk, but did not reach statistical significance. CONCLUSIONS: Our study suggests that genetic variants in systolic pressure-related genotypes may contribute to the etiology of ischemic stroke.

Objectives: To investigate the therapeutic effects of intravenous thrombolysis, intra-artery thrombolysis, mechanical thrombectomy on patients with acute vertebrobasilar occlusion. Methods: Retrospective analysis of clinical data of patients with acute vertebrobasilar occlusion, admitted to Huai'an First People's Hospital and Bingtuan Qishi Hospital from January 2014 to January 2016, was performed. According to different vascular recanalization, these patients were divided into intravenous thrombolysis group, intra-artery thrombolysis group and mechanical thrombectomy group. Clinical outcomes were compared among the three groups such as recanalization rates( modified thrombolysis in cerebral infarction[mTICI]≥2b), changes of NIHSS scores after 24 hours(scores decreased at least 4 points or complete resolution of symptoms), symptomatic cerebral hemorrhage rate(European Cooperative Acute Stroke Study â ¡ standard) and modified Rankin scale(mRS) score improvement 3 months after treatment. Results: Among patients from mechanical thrombectomy group, the recanalization rate was 87.5%(28/32), 22 patients(68.8%)got good outcome according to the significant decrease of NIHSS scores, symptomatic intracranial hemorrhage occurred in 3 patient (9.4%), the rate of good prognosis(mRS≤2) at 3 months was 50.0% (16/32). In patients from intravenous thrombolysis group, the rate of recanalization was 34.8% (16/46), 12 patients(26.1%)got apparent decrease of NIHSS scores, symptomatic cerebral hemorrhage occurred in 14 patients(30.4%), the rate of good clinical outcome(mRS ≤2) at 3 months was 17.4%(8/46). Among patients from intra-arterial thrombolysis group, the recanalization rate was 53.3%(16/30), 12 patients(40.0%) got good outcome according to the significant decrease in NIHSS score, symptomatic intracranial hemorrhage occurred in 6 patients(20.0%), the rate of good prognosis(mRS≤2) at 3 months was 26.7%(8/30). The rate of complete recanalization and NIHSS score improvement at 24 hours were significantly higher in the mechanical thrombectomy group than the intravenous or intra-arterial thrombolysis group(χ(2)=21.324, P<0.001; χ(2)=14.162, P=0.001). The good outcome(mRS≤2) at 3 months was more frequent in the mechanical thrombectomy group than the intravenous or intra-arterial thrombolysis group (χ(2)=9.799, P=0.007). The differences of symptomatic intracranial hemorrhage rate among the three treatment groups were not statistically significant(χ(2)=5.035, P=0.081). Conclusion: As compared with the intravenous or intra-arterial thrombolysis, the mechanical thrombectomy has better efficiency and safety in the treatment of acute vertebrobasilar occlusion.

OBJECTIVE: A long history of inconsistencies in the definitions of the outcome measures for chronic subdural hematomas (CSDHs) has contributed to the controversy over the optimal surgical strategy for CSDH treatment. Clarifying these definitions, reassess the available data, and systematically review the prior literature may provide better insight into the differences in treatment efficacy for CSDH. MATERIALS AND METHODS: The clinical course of CSDH was described with a series of strictly defined outcome measures. PubMed, Cochrane Library, and ScienceDirect databases were searched for comparative studies of two main surgical techniques for CSDH, including burr hole craniotomy (BHC) and twist drill craniotomy (TDC). Data were collected with uniform criteria and analyzed using a random-effects model to estimate the mortality, recurrence, operative failure, and cure rates of each treatment. RESULTS: Twelve comparative studies that examined 2,027 CSDH patients were included. The analysis results indicated that TDC and BHC treatments were similar in the mortality rates (RR, 1.25; 95% CI, 0.83-1.87; I2 = 0%; p = 0.28) and the recurrence rates (RR, 1.29; 95% CI, 0.87-1.92; I2 = 13%; p = 0.21) for CSDH patients. However, TDC had a significantly higher operative failure rate compared with BHC (RR, 0.35; 95% CI, 0.15-0.83; I2 = 0%; p = 0.02), whereas patients treated by a TDC approach tended to achieve higher cure rates compared with BHC (RR, 0.92; 95% CI, 0.86-0.99; I2 = 55%; p = 0.02). CONCLUSIONS: The clarification of the definitions related to CSDH outcome facilitates the interpretation of differences in treatment efficacy. The TDC approach manifested a significantly higher operative failure rate compared with the BHC approach; however, TDC showed a tendency in achieving a long-term neurologic cure.
