The Research on the Paths of Popular Science Education about Myopia Prevention and Control among College Students in the Context of Shifting the Focus Forward

Currently, the number of myopic people in China has reached as high as 600 million, and it shows a trend of “early onset, high incidence, and a high degree of severity”. The issue of myopia among children and adolescents has attracted widespread attention from all sectors of society. Comprehensive myopia prevention and control efforts have been launched nationwide. Popular science education, vision screening, and improving visual environments are effective measures for preventing myopia. However, among the target audience for comprehensive myopia prevention and control, the preschool children group has been neglected, and the work of myopia prevention and control for this group has been significantly weakened and marginalized. Due to insufficient awareness of prevention and control, the hyperopia reserve in the preschool children group is being continuously depleted, leading to the early onset of myopia. In light of this situation, the focus of myopia prevention and control needs to shift forward, and it is worth exploring and pondering how college students with a background in optometry can develop entertaining and engaging popular science education materials and methods.

Early warning prevention and control strategies to reduce perioperative venous thromboembolism in patients with gastrointestinal cancer

BACKGROUND Venous thromboembolism(VTE)is a major cause of unexpected and perioperative in-hospital deaths.It is characterized by high morbidity,high mortality,high misdiagnosis rate,and high missed diagnosis rates.VTE is a common postoperative complication in cancer patients.VTE is preventable,and early identification of risk factors leading to VTE and appropriate early preventive actions can reduce its occurrence and mortality.Presently,there is no uniform standard for the prevention and control of VTE in clinical practice,and hospitals in China lack mature and effective protocols for the assessment,prevention,and treatment of VTE.AIM To explore whether an early warning program could influence the occurrence of deep vein thrombosis(DVT)postoperatively.METHODS This is a comparative retrospective cohort study,which enrolled patients who underwent laparotomic or laparoscopic gastrointestinal tumor resection for gastrointestinal cancer between January 2016 and December 2019.Patients were divided into a control group and an early warning group depending on whether or not the early warning program was implemented.A venous thromboembolism prevention and control team was established.The outcomes included the occurrence of DVT,the correct rate of VTE assessment,the coagulation indicators,and the mastery of VTE knowledge by the nurses.RESULTS A total of 264 patients were included in this study,with 128 patients in the control group and 136 patients in the early warning group.The occurrence rate of DVT in the early warning group was 6.6%(9/136),compared with 14.1%(18/128)in the control group(P<0.05).The correct rates of VTE risk assessment by the nurses and standard implementation rate of VTE preventive measures were 86.8%vs 65.6%and 80.2%vs 57.8%in early warning and control groups,respectively(all P<0.001).The independent factors associated with postoperative DVT occurrence were age(OR=1.083,95%CI:1.070-3.265,P=0.032),Hyperlipidemia(OR=1.127,95%CI:1.139-2.564,P=0.042),preoperative high VTE risk(OR=2.131,95%CI:1.085-5.178,P=0.001),time of operation(OR=2.268,95%CI:2.005-5.546,P=0.026)and not adoption of early warning prevention(OR=3.747,95%CI:1.523-6.956,P=0.017).CONCLUSION The early warning strategy was independently associated with the decreasing occurrence of VTE,and it might be suitable for protection from VTE in patients undergoing gastrointestinal cancer surgery.

Identification of Early Warning Signals of Infectious Diseases in Hospitals by Integrating Clinical Treatment and Disease Prevention

The global incidence of infectious diseases has increased in recent years,posing a significant threat to human health.Hospitals typically serve as frontline institutions for detecting infectious diseases.However,accurately identifying warning signals of infectious diseases in a timely manner,especially emerging infectious diseases,can be challenging.Consequently,there is a pressing need to integrate treatment and disease prevention data to conduct comprehensive analyses aimed at preventing and controlling infectious diseases within hospitals.This paper examines the role of medical data in the early identification of infectious diseases,explores early warning technologies for infectious disease recognition,and assesses monitoring and early warning mechanisms for infectious diseases.We propose that hospitals adopt novel multidimensional early warning technologies to mine and analyze medical data from various systems,in compliance with national strategies to integrate clinical treatment and disease prevention.Furthermore,hospitals should establish institution-specific,clinical-based early warning models for infectious diseases to actively monitor early signals and enhance preparedness for infectious disease prevention and control.

Transient Stability Preventive Control of Wind Farm Connected Power System Considering the Uncertainty

To address uncertainty as well as transient stability constraints simultaneously in the preventive control of windfarm systems, a novel three-stage optimization strategy is established in this paper. In the first stage, the probabilisticmulti-objective particle swarm optimization based on the point estimate method is employed to cope with thestochastic factors. The transient security region of the system is accurately ensured by the interior point methodin the second stage. Finally, the verification of the final optimal objectives and satisfied constraints are enforcedin the last stage. Furthermore, the proposed strategy is a general framework that can combine other optimizationalgorithms. The proposed methodology is tested on the modified WSCC 9-bus system and the New England 39-bussystem. The results verify the feasibility of the method.

Traditional Chinese medicine for acute mountain sickness prevention: A systematic review and meta-analysis of randomized controlled trials

Objective: To evaluate the efficacy of traditional Chinese medicine(TCM) for preventing acute mountain sickness(AMS).Methods: We included randomized controlled trials(RCTs) which evalueded the effect of TCM for preventing AMS, compared with a placebo, no treatment or acetazolamide. The literature was searched in 6major databases. RevMan 5.4 software was used for the meta-analysis. The relative risk for discrete variables and the mean difference for continuous variables with 95% confidence intervals(CIs) were applied to express the effect size. The risk of bias in the included studies was evaluated using the Cochrane risk assessment tool 2.0(RoB 2.0), and the evidence certainty was assessed using the Grading of Recommendations Assessment and the Development and Evaluation(GRADE) approach.Results: Twenty RCTs involving 3015 participants and 16 TCM patent drugs were included. The overall risk of bias in the majority of studies(15/20) was of some concerns. In terms of the AMS incidence,Rhodiola rosea(R. rosea, Hong Jing Tian) and Ginkgo biloba(G. biloba, Yin Xing Ye) were equivalent to the placebo/no treatment [RR(95% CI): 0.66(0.43-1.01), 0.82(0.63-1.06), respectively]. The AMS incidence in the G. biloba group was higher than that in the acetazolamide group [RR(95% CI): 2.92(1.69-5.06)]. In terms of improving the AMS symptom score on days 1 and 3 in the plateau, R. rosea and G. biloba were superior to the placebo or no treatment [MD(95% CI):-0.98(-1.71,-0.25),-2.05(-3.14,-0.95), respectively]. The other 14 Chinese patent medicines were evaluated in a single trial, and the majority of the results were negative. The subgroup analysis showed that the effect of R. rosea was related to the intervention time, way of ascending, and altitude.Conclusion: R. rosea and G. biloba were effective in improving AMS symptoms but had no effect in reducing the AMS incidence. There was insufficient evidence to support the use of other TCM patent drugs to prevent AMS. More randomized double-blind placebo-controlled trials are warranted to evaluate and screen effective Chinese patent medicines for AMS prevention.

Effects of ulinastatin therapy in deep vein thrombosis prevention after brain tumor surgery:A single-center randomized controlled trial

BACKGROUND Venous thromboembolism(VTE)is a common neurosurgical complication after brain tumor resection,and its prophylaxis has been widely studied.There are no effective drugs in the clinical management of venous thromboembolism,and there is an absence of evidence-based medicine concerning the treatment of severe multiple traumas.AIM To explore whether ulinastatin(UTI)can prevent VTE after brain tumor resection.METHODS The present research included patients who underwent brain tumor resection.Patients received UTIs(400,000 IU)or placebos utilizing computer-based random sequencing(in a 1:1 ratio).The primary outcome measures were the incidence of VTE,coagulation function,pulmonary emboli,liver function,renal function,and drug-related adverse effects.RESULTS A total of 405 patients were evaluated between January 2019 and December 2021,and 361 of these were initially enrolled in the study to form intention-to-treat,which was given UTI(n=180)or placebo(n=181)treatment in a random manner.There were no statistically significant differences in baseline clinical data between the two groups.The incidence of VTE in the UTI group was remarkably improved compared with that in the placebo group.UTI can improve coagulation dysfunction,pulmonary emboli,liver function,and renal function.No significant difference was identified between the two groups in the side effects of UTI-induced diarrhea,vomiting,hospital stays,or hospitalization costs.The incidence of allergies was higher in the UTI group than in the placebo group.CONCLUSION The findings from the present research indicated that UTI can decrease the incidence of VTE and clinical outcomes of patients after brain tumor resection and has fewer adverse reactions.
