This study used the Appraisal of Guidelines Research & Evaluation-Health Systems （AGREE-HS） to demonstratively compare 34 global coronavirus disease-2019 （COVID-19） health systems guidance documents （HSGs） and 6 World Health Organization （WHO） standard HSGs. The comparison involved topic， participants， methods， recommendations， and implementability， with the aim of exploring the characteristics of emergency HSGs. The results showed that the emergency HSGs had an overall average score of 49%， with topic having the highest score， recommendations having the second highest score， and participants having the lowest score. The standard HSGs had an overall average score of 79%， with high scores in all items. The emergency HSGs had lower scores in participants， methods， recommendations， and implementability than the standard HSGs （P<0.001）， while the COVID-19 emergency HSGs developed by the WHO had higher score in topic than the standard HSGs （P<0.05）. Compared with those released by countries， the COVID-19 emergency HSG developed by the WHO showed superiority in all items and overall scores （P=0.000 2）. This indicates that emergency HSGs， represented by the COVID-19 emergency HSG， place equal emphasis on topic and recommendations as standard HSGs but have low requirements in terms of expert participation， evidence support， and comprehensive consideration in the time- and resource-limited context. They have the characteristics of prominent topics， clear purposes， orientation to demand， keeping up with the latest evidence， flexible adjustment， and timeliness， emphasizing immediate implementation effects， weakening long-term effects， and focusing on comprehensive benefits. Additionally， developers， types， and report completeness are important influencing factors.

Objective:To summarize the relevant evidence for the management of fixation in traumatic spinal cord injury patients, which provides a reference for the clinical care and care of patients.Methods:A systematic search was conducted for evidence related to spinal injuries from domestic and foreign databases, relevant guideline websites, etc. The types of literature were best practice, expert consensus, systematic review, evidence summary, clinical decision-making, etc. The search time was from the establishment of databases to January 31, 2022. Three researchers used the Multidimensional Systematic Review Tool to evaluate systematic review literature. Five researchers used the guideline research and evaluation tool AGREE Ⅱ to evaluate clinical practice guidelines, and used the Australian JBI Evidence-Based Health Care Center (2016) to evaluate expert consensus and expert opinion with the authenticity evaluation tool for expert opinions and professional consensus articles. And extracted and summarized evidence according to the subject.Results:Finally, 10 articles were included, including 4 clinical decision-making, 4 guidelines and 2 systematic evaluations. The 30 pieces of evidence include the assessment, prevention, cervical spinal fixation, and management after traumatic spinal cord injury.Conclusions:The evidence emphasizes the importance of standardized assessment of cervical risk factors in all emergency adult patients with traumatic spinal cord injury. In the emergency department, we need to improve the ability of spinal evaluation and fixation in patients with penetrating neck injury, optimize the timeliness process of emergency trauma, reduce the occurrence of potential complications, and improve patient outcomes.

Objective:To investigate the risk factor of hepatocellular carcinoma (HCC) with vessels encapsulating tumor clusters (VETC) and the application value of its risk scoring model.Methods:The retrospective cross-sectional study was conducted. The clinicopathological data of 149 patients with HCC who were admitted to two medical centers, including 97 cases in the Jiangnan University Medical Center and 52 cases in the Affiliated Xingtai People′s Hospital of Hebei Medical University, from January 2017 to April 2020 were collected. There were 116 males and 33 females, aged (58±12)years. There were 74 cases with VETC and 75 cases without VETC. Observation indica-tors: (1) clinical characteristics of patients with and without VETC; (2) imaging features of patients with and without VETC; (3) multivariable analysis of HCC patients with VETC; (4) construction of VETC related risk scoring model and its performance evaluation; (5) postoperative early tumor recurrence of patients with and without VETC who were confirmed by risk scoring model and histopathological examination. Measurement data with normal distribution were represented as Mean± SD, and comparison between groups was conducted using the t test. Count data were described as absolutes, and comparison between groups was conducted using the chi-square test and continuous correction chi-square test. Variables of clinical and imaging characteristics with statistically signifi-cant were included in the multivariate analysis. Multivariate analysis was conducted using the Logistic regression model of backward stepwise selection. VETC related risk scoring model was constructed based on the results of Logistic regression model. The receiver operating characteristic (ROC) curve was drawn, and the area under curve (AUC), the sensitivity, specificity, accuracy and their 95% confidence interval ( CI) were calculated. The maximizing Youden index was the optimal cutoff value for VETC prediction. The Hosmer Lemeshow goodness of fit test was used to assess the consistency between VETC risk scoring model predicted VTEC status and the true VETC status. The Kaplan-Meier method was used to calculate survival rates and draw survival curves. The Log-rank test was used for survival analysis. Results:(1) Clinical characteristics of patients with and without VETC. Cases with postoperative albumin <36 g/L were 57 in patients with VETC, versus 68 in patients without VETC, respectively, showing a significant difference between them ( χ2=5.13, P<0.05). (2) Imaging features of patients with and without VETC. Cases with lesion imaging presence as nonperipheral washout, cases with lesion imaging presence as mosaic architecture, cases with lesion imaging presence as intratumoral hemorrhage, cases with lesion imaging presence as corona enhancement, cases with lesion imaging presence as non-smooth tumor margin, cases with lesion imaging presence as peritumoral enhancement in arterial phase, cases with lesion imaging presence as intratumoral arteries, cases with lesion imaging presence as peritumoral hypointensity in hepatobiliary phase, cases with lesion imaging enhancement type as uniform low enhancement, uniform high enhance-ment, heterogeneous enhancement with septations and heterogeneous enhancement with irregular ring-like structures, cases with intratumoral necrosis or ischemic, cases with tumor diameter >5 cm were 73, 35, 33, 15, 39, 28, 42, 27, 4, 5, 27, 38, 45, 46 in patients with VETC, versus 64, 16, 13, 3, 19, 15, 9, 13, 9, 35, 5, 26, 10, 10 in patients without VETC, respectively, showing significant differences in the above indicators between them ( χ2=8.92, 11.15, 12.97, 9.28, 11.74, 5.77, 33.14, 6.96, 41.79, 36.05, 37.86, P<0.05). (3) Multivariable analysis of patients with VETC. Results of multivariable analysis showed that lesion imaging enhancement as heterogeneous enhancement with septations, lesion imaging enhancement as heterogeneous enhancement with irregular ring-like structures, intratumoral necrosis or ischemia and tumor diameter >5 cm were independent risk factors influen-cing patients with VETC ( odds ratio=4.18, 7.62, 4.23, 4.08, 95% CI as 1.60?11.60, 2.00?31.70, 1.71?10.90, 1.60?10.80), P<0.05). (4) Construction of VETC related risk scoring model and its performance evaluation. The VETC related risk scoring model was constructed as (heterogeneous enhancement with septations, presence: 1.0, absence: 0)+(heterogeneous enhancement with irregular ring-like structures, presence: 1.5, absence: 0)+(intratumoral necrosis or ischemia, presence: 1.0, absence: 0)+(main tumor diameter >5 cm, presence: 1.0, absence: 0). The AUC, sensitivity, specificity, and accuracy of VETC related risk scoring model were 0.86 (95% CI as 0.80?0.92), 79.7% (95% CI as 69.2%?87.3%), 80.0% (95% CI as 69.6%?87.5%) and 79.9% (95% CI as 72.7%?85.5%), respectively. Results of Hosmer-Lemeshow goodness of fit test showed a good consistency between VETC risk scoring model predicted VETC status and true VETC status ( P>0.05). (5) Postoperative early tumor recurrence of patients with and without VETC who were confirmed by risk scoring model and histopathological examination. All 149 patients were followed up for 29(range, 26?35)months. The time to tumor recurrence and 2-year cumulative tumor recurrence rate of 149 patients were 29(range, 24?33)months and 43.0%, respectively. The 2-year tumor cumulative recurrence rate of patients with and without VETC predicted by risk scoring model was 47.8% and 37.9%, respectively, showing a significant difference between ( χ2=3.90, P<0.05). The 2-year cumulative tumor recurrence rate of patients with and without VETC confirmed by postoperative histopathological examination was 47.4% and 38.1%, respectively, showing a significant difference between ( χ2=4.20, P<0.05). Conclusions:Lesion imaging enhancement as heterogeneous enhancement with septations or irregular ring-like structures, intratumoral necrosis or ischemia and tumor diameter >5 cm are independent risk factors influen-cing HCC patients with VETC. The proposed risk scoring model based on those three risk factors achieves an optimal preoperative diagnostic performance.

Objective:To compare the therapeutic effect of polysaccharide iron complex capsule and Shengxuening tablet on renal anemia in maintenance hemodialysis (MHD) patients.Methods:Patients who received MHD treatment from April to June 2016 in our dialysis center and met the criteria for iron deficiency anemia were block-randomly divided into two groups: the polysaccharide-iron complex group and the Shengxuening group. Blood routine, iron metabolism biomarkers and biochemical exams were measured before treatment and at the 1st, 2nd and 3rd months after treatment, and the incidence of adverse reactions were recorded. The compliance rate of the two groups was observed and compared, and the block-randomized-statistical methods were used to compare the clinical data of the two groups before and after treatment, and cost-benefit analysis was also conducted.Results:Thirty patients in each group completed follow-up. After three months of treatment, the blood routine and iron metabolism indicators of the two groups were improved. Compared with the Shengxuening group, the polysaccharide iron complex group had higher therapeutic efficiency, and the levels of hemoglobin, transferrin saturation and serum ferritin were higher, and lower use of recombinant human erythropoietin ( P<0.05). The other indexes such as red blood cell (RBC), hematocrit (HCT) levels and the effective rate of anemia correction, the effective rate of iron therapy, the effective rate of iron therapy between the two groups were similar. Cost-benefit analysis suggested that the use of polysaccharide iron complexes to treat anemia has lower costs and higher benefits ( P<0.05). Conclusions:Polysaccharide iron complex capsule can better correct anemia and improve iron metabolism, and has low cost-effectiveness, which can effectively reduce medical insurance expenditure. It is a good iron supplementing method in addition to intravenous iron supplement.

Objective To produce a plastic ampoule with an opening that fits syringe adapters to allow solutions to be drawn up without needles (to avoid needle stick and sharps injuries) and to test the effectiveness of the new design in terms of residual fluid volume and risk of microorganism contamination. Methods Evaluation study based on laboratory research was adopted. For the experimental group, 30 ampoules based on the new design were produced by 3D printing. The ampoules were sterilized and filled with 2 ml sterile water. The sterile water was drawn up without the use of needles, and the wastage fluid (i.e., 2 ml minus the quantity drawn up) was calculated. A 1 ml aliquot of sterile water from each ampoule was dropped onto a nutrient agar plate, and the number of colony-forming units was assessed after 48 h. For each ampoule, the experiment was performed twice. Sixty 2 ml glass-packaged sterile water injections constituted the control group. The fluid was drawn up with a needle, and the superfluous fluid and number of colony-forming units were assessed, as in the experimental group. Results The mean wastage fluid was 0.06 ml, 95% CI was 0.05-0.07 ml in the experimental group and the superfluous fluid was 0.06 ml, 95% CI was 0.06-0.07 ml in the control group, there was no significant difference between the two groups (Z=-1.194, P=0.233). The number of colony-forming units was 8 in the experimental group and 4 in the control group, there was no significant difference between the two groups (P=0.224). Conclusions The newly designed plastic ampoule opening could help health workers to avoid needle stick and sharps injuries when drawing up solution. The wastage fluid and microorganism contamination levels met the required standards, indicating that the new design is suitable for clinical application.
