Cardiac cephalalgia is a rare disease caused by underlying coronary artery disease that presents as headache with or without chest symptoms.Headache symptoms are often caused by referred pain,increased intracranial pressure and release of large amounts of pain-causing neurochemicals due to myocardial ischemia,and cortical hypoperfusion.Due to the low overall prevalence of the disease,the lack of chest pain typical of coronary heart disease,and the fact that it may be difficult to distinguish from headaches caused by neurological diseases,accurate diagnosis and treatment of the disease are often delayed.We report a case of acute coronary syndrome with headache only.Revascularization was achieved through percutaneous coronary intervention therapy,followed by standard secondary prevention pharmacotherapy.Follow-up six months postoperatively showed a significant improvement in exercise tolerance,with no further headache episodes.The purpose is to improve the understanding of patients with cardiac cephalalgia,with a view to early identification and timely intervention,and ultimately improve the symptoms and prognosis.

Objective:To analyze the effects of highdose methotrexate(HD-MTX)and lenalidomide as central nervous system(CNS)prophylaxis strategies in patients with diffuse large B-cell lymphoma(DLBCL).Methods:The data of DLBCL patients with high risk of CNS recurrence who were initially treated in Fujian Provincial Hospital and Fujian Cancer Hospital from January 2012 to June 2022 were analyzed retrospectively.The patients were divided into HD-MTX group and lenalidomide group according to different prophylaxis strategies.Each group was further divided into high-risk group and medium-risk group based on CNS-IPI score and/or testicular involvement.The CNS relapse-free survival(CRFS)rate,adverse effects,and the effects of different prophylaxis strategies on overall survival(OS)rate and progression-free survival(PFS)rate were evaluated in different groups and subgroups.Results:There were 200 patients enrolled in this study,80 cases in lenalidomide group and 120 cases in HD-MTX group.According to the delivery timing of prophylactic HD-MTX,the patients in HD-MTX group were further divided into two groups:80 cases at the end of induction chemotherapy and 40 cases during chemotherapy interval.At a median follow-up of 48(14-133)months,the 4-year CRFS rate,4-year PFS rate,and 4-year OS rate of the HD-MTX group was 93.6％,57.2％,and 68.8％,respectively,while that of the lenalidomide group was 90.4％,69.4％and 75.6％.There were no significant differences in 4-year CRFS rate,4-year PFS rate,and 4-year OS rate between HD-MTX group and lenalidomide group(all P＞0.05),but lenalidomide group showed a trend of improvement in PFS.Further subgroup analysis showed that there was no significant difference in 4-year CRFS rate between high-risk patients of the two groups(91.7％vs 83.4％,P＞0.05),while 4-year PFS rate showed difference(49.5％vs 64.2％,P＜0.05).A total of 248 cycles were collected for adverse reaction analysis in the HD-MTX group,and 25 cycles occurred neutropenia accompanied with infection(10.1％),while in lenalidomide group 240 cycles were collected in which 20 cycles occurred neutropenia accompanied with infection(8.3％).Both the two groups had no treatment-related deaths.Conclusion:Compared with HD-MTX,lenalidomide combined with immunochemotherapy can prevent CNS relapse,at the same time,improve prognosis,which is a safe and well tolerated central prophylaxis strategy.

Rutin is extracted from Ruta graveolens L. with many pharmacological activities such as anti-inflammation, anti-oxidation , protecting cardiovascular system and analgesia. As a natural product, rutin has the advantages of low side effects and difficult tolerance, but its instability and low bioavailability still limit its clinical application. This paper summarizes the analgesic mechnism of rutin, and looks forward to the clinical applica¬tion of rutin based on its derivative and dosage forms. It is expected to provide ideas for further analgesic research and drug development and application of rutin in the future.

The year 2020 is an extremely unusual year. The world lost more than one million lives due to the attack of COVID-19. Economic production has been greatly reduced, and daily activities are largely restricted. Luckily the work of Chinese Journal of Traumatology (CJTEE) has not been adversely affected. 2020 is a harvest year for the journal, which (1) was included in the high-quality academic journals by China Association for Science and Technology; (2) cover of each issue is newly designed; (3) submission increased by about 60% with more countries and regions covered; (4) usage in the ScienceDirect database exceeded a million; (5) the CiteScore rises to more than 2.0 the first time. This study reviewed the articles published in the year 2020 by CJTEE.

Throughout the past 2020, the pandemic COVID-19 has caused a big global shock, meanwhile it brought a great impact on the public health network. Trauma emergency system faced a giant challenge and how to manage trauma under the pandemic of COVID-19 was widely discussed. However, the trauma treatment of special population (geriatric patients and patients taking anticoagulant drugs) has received inadequate attention. Due to the high mortality following severe traumatic hemorrhage, hemostasis and trauma-induced coagulopathy are the important concerns in trauma treatment. Sepsis is another topic should not be ignored when we talking about trauma. COVID-19 itself is a special kind of sepsis, and it may even be called as serious systemic infection syndrome. Sepsis has been become a serious problem waiting to be solved urgently no matter in the fields of trauma, or in intensive care and infection, etc. This article reviewed the research progress in areas including trauma emergency care, trauma bleeding and coagulation, geriatric trauma and basic research of trauma within 2020.

The COVID-19 pandemic is still raging across the world. Everyday thousands of infected people lost their lives. What is worse, there is no specific medicine and we do not know when the end of the pandemic will come. The nearest global pandemic is the 1918 influenza, which caused about 50 million deaths and partly terminate the World War Ⅰ. We believe that no matter the virus H1N1 for the 1918 influenza or 2019-nCoV for COVID-19, they are essentially the same and the final cause of death is sepsis. The definition and diagnostic/management criteria of sepsis have been modified several times but the mortality rate has not been improved until date. Over decades, researchers focus either on the immunosuppression or on the excessive inflammatory response following trauma or body exposure to harmful stimuli. But the immune response is very complex with various regulating factors involved in, such as neurotransmitter, endocrine hormone, etc. Sepsis is not a kind of disease, instead a misbalance of the body following infection, trauma or other harmful stimulation. Therefore we should re-think sepsis comprehensively with the concept of systemic biology, i.e. inflammationomics.

BACKGROUND: Some porous materials have been developed to enhance biologic fusion of the implants to bone in spine fusion surgeries. However, there are several inherent limitations. In this study, a novel biomedical porous tantalum was applied to in vitro and in vivo experiments to test its biocompatibility and osteocompatibility. METHODS: Bone marrow-derived mesenchymal stem cells (BMSCs) were cultured on porous tantalum implant. Scanning electron microscope (SEM) and Cell Counting Kit-8 assay were used to evaluate the cell toxicity and biocompatibility. Twenty-four rabbits were performed discectomy only (control group), discectomy with autologous bone implanted (autograft group), and discectomy with porous tantalum implanted (tantalum group) at 3 levels: L3-L4, L4-L5, and L5-L6 in random order. All the 24 rabbits were randomly sacrificed at the different post-operative times (2, 4, 6, and 12 months; n = 6 at each time point). Histologic examination and micro-computed tomography scans were done to evaluate the fusion process. Comparison of fusion index scores between groups was analyzed using one-way analysis of variance. Other comparisons of numerical variables between groups were made by Student t test. RESULTS: All rabbits survived and recovered without any symptoms of nerve injury. Radiographic fusion index scores at 12 months post-operatively between autograft and tantalum groups showed no significant difference (2.89 ± 0.32 vs. 2.83 ± 0.38, F = 244.60, P = 0.709). Cell Counting Kit-8 assay showed no significant difference of absorbance values between the leaching liquor group and control group (1.25 ± 0.06 vs. 1.23 ± 0.04, t = -0.644, P = 0.545), which indicated the BMSC proliferation without toxicity. SEM images showed that these cells had irregular shapes with long spindles adhered to the surface of tantalum implant. No implant degradation, wear debris, or osteolysis was observed. Histologic results showed solid fusion in the porous tantalum and autologous bone implanted intervertebral spaces. CONCLUSION This novel porous tantalum implant showed a good biocompatibility and osteocompatibility, which could be a valid biomaterial for interbody fusion cages.

OBJECTIVE: Previous studies have indicated that the plasticizer di (2-ethylhexyl) phthalate (DEHP) affects lipid accumulation; however, its underlying mechanism remains unclear. We aim to clarify the effect of DEHP on lipid metabolism and the role of TYK2/STAT1 and autophagy. METHODS: In total, 160 Wistar rats were exposed to DEHP [0, 5, 50, 500 mg/(kg•d)] for 8 weeks. Lipid levels, as well as mRNA and protein levels of TYK2, STAT1, PPARγ, AOX, FAS, LPL, and LC3 were detected. RESULTS: The results indicate that DEHP exposure may lead to increased weight gain and altered serum lipids. We observed that DEHP exposure affected liver parenchyma and increased the volume or number of fat cells. In adipose tissue, decreased TYK2 and STAT1 promoted the expression of PPARγ and FAS. The mRNA and protein expression of LC3 in 50 and 500 mg/(kg•d) groups was increased significantly. In the liver, TYK2 and STAT1 increased compensatorily; however, the expression of FAS and AOX increased, while LPL expression decreased. Joint exposure to both a high-fat diet and DEHP led to complete disorder of lipid metabolism. CONCLUSION It is suggested that DEHP induces lipid metabolism disorder by regulating TYK2/STAT1. Autophagy may play a potential role in this process as well. High-fat diet, in combination with DEHP exposure, may jointly have an effect on lipid metabolism disorder.
