Emergency treatment of ocular trauma is a systematic and complicated work. Rapid and correct diagnosis and treatment are needed to maximize the recovery of ocular structure and function. In recent years, China has made remarkable progress in the emergency treatment of ocular trauma, including the development of Expert consensus on the norms of emergency treatment of ocular trauma in China (2019), the establishment of a national ocular trauma database, and the development of VisionGo Artificial Intelligence prediction system for ocular trauma. These measures improve the treatment level of ocular trauma and provide support for the prediction of postoperative visual acuity in severe traumatic eyes. However, with the development of economy and society, the characteristics of ocular trauma in our country have changed. For example, the majority of hospitalized patients were open ocular injuries, farmers and workers were the main occupational groups, and the proportion of eye injuries caused by traffic injuries increased year by year, and the proportion of women and minors increased. Although the annual loss of life of ocular trauma disability in China has decreased faster than the world average, the emergency treatment of ocular trauma still faces many challenges, such as regional differences, insufficient primary medical resources, lack of standardized training, and insufficient promotion of emergency treatment standards. In order to cope with these challenges, it is necessary to further strengthen the popularization of science and technology for the prevention and treatment of ocular trauma, standardize the emergency treatment process, strengthen the training of grass-roots medical personnel, strengthen the safety of emergency surgery, and pay special attention to the particularity of children's ocular trauma. In addition, relevant research has been actively carried out to establish a complete database of emergency patients with ocular trauma to promote the accurate prevention and treatment of ocular trauma.
Objective To retrospectively analyze and classify 23 open fractures that resulted in severe infection, in order to provide evidence that can be used in future disaster scenarios. Methods Based on medical records of 23 cases of open fracture and subsequent bacterial infection, we analyzed the clinical diagnosis, treatment, laboratory tests, bacterial smear of wound secretion, and the bacterial culture of the wound secretion. We then analyzed which antimicrobial agents were used and how they were applied, and the subsequent effect on controlling the serious infection.? Results All cases were related to seismic injury and belonged to class VI open fracture. Eight cases were male and 15 were female. All cases had similar symptoms such as chills, fever, large scale muscle necrosis, and severe infection. A direct smear of the wound showed that the number of cases with one bacterial infection was 6 (26.09%), the number that had double bacterial infections was 12 (52.18%), and the number with multiple bacterial infections was 5 (21.74%).There were 18 strains of 11 types of bacteria recovered from wound samples. Conclusion Early treatment with the joint application of multiple antibacterial agents, early debridement, and adequate drainage all helped to control the infection and avoid nosocomial infection. Employing these strategies in the future will control infection in disaster situations.
ObjectiveTo systematically review the efficacy and safety of probiotics-containing rescue regimen for the eradication of Helicobacter pylori (Hp) infection. MethodsWe electronically searched PubMed, EMbase, Cochrane Central Register of Controlled Trials (CENTRAL), CBM, CNKI, WanFang Data and VIP databases, and Chinese Clinical Trial Register (ChiCTR) and ClinicalTrial.gov from inception to December 2015, to collect randomized controlled trials (RCTs) about probiotics-containing rescue regimen for the eradication of Hp infection. Two reviewers independently screened literature, extracted data, and assessed the risk of bias of included studies. Then, meta-analysis was performed by using RevMan 5.3 software. ResultsEleven RCTs involving 1888 patients were finally included. The results of meta-analysis showed that: Compared with the control group, probiotics-containing rescue regimen could significantly increase the eradication rate (ITT analysis: 80.3% vs. 69.3%, RR =1.15, 95%CI 1.10 to 1.22, P<0.00001; PP analysis: 86.5% vs. 74.3%, RR=1.16, 95%CI 1.11 to 1.22, P<0.00001), and decrease the incidence of total adverse reaction (ITT analysis: 19% vs. 29.2%, RR=0.60, 95%CI 0.40 to 0.91, P=0.02). Sensitivity analysis showed that the result was relatively stable. Publication bias test showed no evidence of substantial publication bias. ConclusionCurrent evidence indicates that probiotics-containing rescue regimen may contribute to improve eradication rate of Hp infection patients, and may reduce the occurrence of major gastrointestinal associated adverse reaction. Due to the limited quality and quantity of included studies, more high-quality RCTs are needed to verify the above conclusion.
ObjectiveTo analyze the efficacy and safety of various treatment strategies for patients with refractory/recurrent diffuse large B-cell lymphoma (r/r-DLBCL) by network meta-analysis. MethodsThe PubMed, EMbase and Cochrane Library databases were searched to collect randomized controlled trials (RCTs) and clinical controlled trials related to the objectives of the study from inception to November 16th, 2022. After two investigators independently screened the literature, extracted data and evaluated the risk of bias of the included studies, a network meta-analysis was performed using R 4.2.2 software. ResultsA total of 8 RCTs and 11 non-randomized controlled trials were included, involving 2 559 cases. The treatment regimen included chemotherapy, immunochemotherapy, chemotherapy combined with ADC, immunochemotherapy combined with ADC, ASCT based regimen, CAR-T based regimen, ASCT combined with CAR-T, immunomodulators, small molecule inhibitors, and rituximab combined with small molecule inhibitors. The ranking probability results showed that the top three complete remission (CR) rates among all schemes were ASCT combined with CAR-T, chemotherapy combined with ADC, and immune modulators; The top three overall response rates (ORR) were chemotherapy combined with ADC, ASCT combined with CAR-T, and ASCT. The CAR-T regimen had a higher rate of severe neutropenia; The severe thrombocytopenia rate of ASCT regimen was relatively high; There was no significant difference in the incidence of SAEs among the other options. ConclusionASCT combined with CAR-T and chemotherapy combined with ADC have the best therapeutic effects on r/r-DLBCL. However, the specific protocol to be adopted requires clinical doctors to combine actual conditions, comprehensively consider the efficacy and side effects, and develop personalized treatment strategies for r/r-DLBCL patients.

Ocular trauma is the most common cause of monocular vision loss in children. Among the patients with eye trauma in China, 15%-20% are children. The complexity of diagnosis and treatment and the uncertainty of prognosis are high because the ocular tissue of children is not fully developed and the history collection and examination are difficult. In order to further standardize the treatment of children's eye trauma and improve the treatment level, China Ocular Trauma Society has formulated Expert consensus of the treatment of pediatric ocular trauma in China by combining domestic and foreign literature and the actual medical situation in China. This consensus provides detailed recommendations on the classification, cause of injury, history collection, examination methods, diagnosis and treatment principles of pediatric eye trauma. This consensus applies to Chinese ophthalmologists and medical personnel engaged in the treatment of children's eye trauma, aiming to provide scientific guidance for the diagnosis and treatment of children's eye trauma, assist clinical decision-making, and further improve the treatment level of children's eye trauma in China.
Through reviewing the regulations on the right of emergency treatment of hospitals, we analyzed reasons of emergency treatment of hospitals, including uninformed patients and informed patients without consent in emergency situations, as well as the risk of emergency rescue of hospitals. We put forward how to consider the judgment of emergency situations, justification of emergency treatment of hospitals, and risk attribution. We suggested improving the related legislation and regulations, developing compulsory medical insurance and a medical rescue system on emergency treatment.
