RESUMO

History records show that pandemics and threats have always given new directions to the thinking, working, and learning styles. This article attempts to thoroughly document the positive core of coronavirus 2019 (COVID-19) and its impact on global social psychology, ecological stability, and development. Structural equation modeling (SEM) is used to test the hypotheses and comprehend the objectives of the study. The findings of the study reveals that the path coefficients for the variables health consciousness, naturalism, financial impact and self-development, sustainability, compassion, gregariousness, sympathy, and cooperation demonstrate that the factors have a positive and significant effect on COVID-19 prevention. Moreover, the content analysis was conducted on recently published reports, blog content, newspapers, and social media. The pieces of evidence from history have been cited to justify the perspective. Furthermore, to appraise the opinions of professionals of different walks of life, an online survey was conducted, and results were discussed with expert medical professionals. Outcomes establish that the pandemics give birth to creativity, instigate innovations, prompt inventions, establish human ties, and foster altruistic elements of compassion and emotionalism.

RESUMO

The essential challenge of gene therapy is to develop safe and efficient vectors that escort genes to target sites. However, due to the cumbersome workflow of gene transfection into cells, successive gene loss occurs. This leads to considerable reductions in nuclear gene uptake, eventually causing low gene expression. Herein, we designed a gene vector named CA3S2 (C: N,N'-cystamine-bis-acrylamide [CBA], A: agmatine dihydrochloride [Agm], S: 4-(2-aminoethyl) benzenesulfonamide [ABS]) with excellent gene transfection ability. This vector can promote gene delivery to the nucleus via enhanced endoplasmic reticulum (ER) targeting through integrating and streamlining of the complex intracellular pathway. Briefly, ABS endowed CA3S2/DNA nanoparticles with not only a natural ER-targeting tendency attributed to the caveolae-mediated pathway but also direct receptor-binding capacity on the ER surface. Agm enabled CA3S2 to enhance lysosomal escape and nuclear uptake ability. The gene delivery efficiency of CA3S2 was significantly better than that of polyethyleneimine 25K (PEI 25K). Therefore, CA3S2 is a promising gene carrier, and the ER-targeting strategy involving intracellular pathway integration and streamlining has potential for gene therapy.

RESUMO

Background: Tai Chi that originated in China as a martial art is an aerobic exercise with low-to-moderate intensity and may play a role in cardiac rehabilitation. Aim: To systematically review the effect of Tai Chi on cardiorespiratory fitness for coronary disease rehabilitation. Methods: We performed a search for Chinese and English studies in the following databases: PubMed, EMBASE, Cochrane Central Register of Controlled Trials, Chinese Biomedical Literature Database, China Knowledge Resource Integrated Database, Wanfang Data, and China Science and Technology Journal Database. The search strategy included terms relating to or describing Tai Chi and coronary disease, and there were no exclusion criteria for other types of diseases or disorders. Further, bibliographies of the related published systematic reviews were also reviewed. The searches, data extraction, and risk of bias (ROB) assessments were conducted by two independent investigators. Differences were resolved by consensus. RevMan 5.3.0 was used to analyze the study results. We used quantitative synthesis if the included studies were sufficiently homogeneous and performed subgroup analyses for studies with different control groups. To minimize bias in our findings, we used GRADEpro to grade the available evidence. Results: Five studies were enrolled-two randomized controlled trials (RCTs) and three nonrandomized controlled trials (N-RCTs)-that included 291 patients. All patients had coronary disease. ROB assessments showed a relatively high selection and detection bias. Meta-analyses showed that compared to other types of low- or moderate-intensity exercise, Tai Chi could significantly improve VO2max [MD = 4.71, 95% CI (3.58, 5.84), P < 0.00001], but it seemed less effective at improving VO2max as compared to high-intensity exercise. This difference, however, was not statistically significant [MD = -1.10, 95% CI (-2.46, 0.26), P = 0.11]. The GRADEpro showed a low level of the available evidence. Conclusion: Compared to no exercise or other types of exercise with low-to-moderate intensity, Tai Chi seems a good choice for coronary disease rehabilitation in improving cardiorespiratory fitness. However, owing to the poor methodology quality, more clinical trials with large sample size, strict randomization, and clear description about detection and reporting processes are needed to further verify the evidence.

RESUMO

PURPOSE: Surgery is regarded as a common treatment option for patients with mesial temporal lobe epilepsy (MTLE) as a result of hippocampal sclerosis (HS). However, approximately one-third of patients with intractable epilepsy did not become seizure-free after tailored resection strategies. It would be compelling to identify predictive factors of postoperative seizure outcomes. Our aim was to assess the correlation between HS classification and long-term postoperative seizure outcome in patients with MTLE due to HS. METHODS: To investigate HS classification, semi-quantitative analysis and immunohistochemical staining of neuronal nuclei (NeuN) were performed on 100 postoperative hippocampal specimens. All patients had a 1-7 year postoperative follow-up. The postoperative seizure outcome was evaluated using International League Against Epilepsy (ILAE) outcome classification. RESULTS: Three types of HS were recognized. The highest incidence of initial precipitating injury (IPI) was noted in the HS ILAE type 1 group (53.1%). The most favorable long-term seizure outcome was also noted in the HS ILAE type 1 group. The shortest epilepsy duration was recorded in the HS ILAE type 2 group (mean epilepsy duration=6.64 ± 5.83 years). The completely seizure free rate of patients in all groups declined with an increase in time. CONCLUSIONS: Our study for the first time demonstrated a significant correlation between HS ILAE types and long-term postoperative seizure outcome in patients with MTLE due to HS. Therefore, HS ILAE types have predictive value in long-term seizure outcome following epilepsy surgery.

RESUMO

OBJECTIVES: To investigate the function of cytokines, chemokines, and regulatory T cells (Tregs) in the pathogenesis of type 1 diabetes mellitus (T1DM) in children. METHODS: A total of 35 children with T1DM and 30 healthy controls were enrolled in this study. Levels of serum cytokines (IL-1α, IL-6, IL-10, IL-12, and TNF-α) and chemokines (MIP-1α, MIP-1α and MCP-1) were detected by enzyme-linked immunosorbent assay. Peripheral blood mononuclear cells (PBMCs) were isolated and culture supernatant of phytohaemagglutinin (PHA)-stimulated PBMCs was subjected to ELISA for levels of cytokines (IL-1α, IL-6, IL-10, IL-12 and TNF-α) in T1DM and control group. Furthermore, flow cytometry was used to determine the percentage of Tregs in PBMCs of two groups. RESULTS: Levels of serum cytokines including IL-1α, IL-6, IL-10 and TNF-α as well as chemokines, such as MIP-1α and MIP-1α in children with T1DM children were significantly higher than those in healthy controls (P<0.05, respectively). PBMCs with PHA stimulation in T1DM group secreted more IL-1α and TNF-α (P<0.05, respectively), but less IL-10 (P<0.05), as compared with control group. Furthermore, the proportion of CD4(+), CD25(+), Foxp3(+), Tregs in PBMCs isolated from children with T1DM was obviously lower than those in healthy controls (P<0.05). CONCLUSIONS: Immune dysfunction, with upregulation of inflammatory factors such as IL-1α, IL-6, TNF-α and MIP-1α, downregulation of IL-10 and Tregs, plays an important role in the pathogenesis of T1DM in children.

RESUMO

We evaluated the long-term outcome of epilepsy surgery in drug-resistant epilepsy patients, and investigated preoperative factors associated with postoperative long-term surgical outcome. We performed a retrospective study of 379 patients who received epilepsy surgeries from 2000 to 2010. Patients had completed a minimum of 2-year and up to 12-year follow-up. Preoperative evaluations, surgical outcomes and clinical data of patients were collected and analyzed. We found that the epilepsy surgery was effective in drug-resistant patients and the long-term outcome of epilepsy surgery was satisfactory. The bipolar electro-coagulation could improve the surgical outcome when the epileptogenic focus was on the functional cortex. Results of the 2-year follow-up showed that preoperative seizure characteristics including the history of febrile seizure, seizure frequency, and location, quantity and range of seizure foci were significantly associated with the surgical outcome. The surgery procedure including the surgery type and the extent of resection also affected outcome. Abnormal head or hippocampus MRI, inconsistent results of preoperative investigations, seizure types, and pathology type might also be predictors of long-term surgical outcome.

RESUMO

Previous research has consistently shown that the left parietal cortex is critical for numerical processing, but the role of the right parietal lobe has been much less clear. This study used the intraoperative cortical electrical stimulation approach to investigate neural dissociation in the right parietal cortex for subtraction and multiplication. Results showed that multiplication (as well as picture naming) was not affected by the cortical electrical stimulation on all the targeted sites of the right parietal cortex as well as those of the right temporal cortex. In contrast, stimulation at three right parietal sites (two sites in the right inferior parietal lobule and one in the right angular gyrus) impaired performance on simple subtraction problems. This study provided the first evidence from an intraoperative cortical electrical stimulation study to show the dissociation of arithmetic operations in the right parietal cortex. This dissociation between subtraction and multiplication suggests that the right parietal cortex plays a more significant role in quantity processing (subtraction) than in verbal processing (multiplication) in numerical processing.

RESUMO

BACKGROUND: Numerical processing is important in our everyday lives. However, very few attempts have been made to map the numerical processing function areas during lesion surgery. OBJECTIVE: To identify and protect the cortical areas involved in numerical processing, the authors used the intraoperative brain mapping approach to study numerical processing areas in patients with parietal lobe tumors. METHODS: During resection in patients with parietal lobe tumors, local anesthesia was administered and numerical processing mapping was performed. Our mapping procedures were conducted before glioma removal and included somatosensory, language and numerical processing tasks. We focused on the numerical processing task. RESULTS: Different brain sites within the parietal lobe were detected to be specifically related to multiplication or subtraction processing. They displayed precise spatial distribution and overlapped with each other. No brain sites were found to be specifically related to numerical processing in the right hemisphere. CONCLUSIONS: To improve the quality of resection while minimizing the neurological deficits, functional boundaries of numerical processing areas should be considered during the removal of a parietal low-grade glioma. Moreover, only the left intraparietal sulcus is necessary for numerical processing, whereas the right intraparietal sulcus does not appear to be critically involved in numerical processing.

RESUMO

BACKGROUND: Recent advances on functional mapping have enabled us to conduct surgery on gliomas within the eloquent area. The objective of the article is to discuss the feasibility of a planned fractionated strategy of resection on low-grade gliomas (LGGs) involving Broca's area. We report the first surgical series of planned fractionated resections on LGGs within Broca's area, focusing on language functional reshaping. METHODS: Four patients were treated with fractionated operations for LGGs involving Broca's area. All cases underwent conventional magnetic resonance (MR) scanning, language functional MR and diffusion tensor imaging (DTI) before operation. The resections were then performed on patients under awake anesthesia using intraoperative electrical stimulation (IES) for functional mapping. Pre- and post-operative neuro-psychological examinations were evaluated. RESULTS: Total resections were achieved in all cases as confirmed by the postoperative control MR. After transient language worsening, all patients recovered to normal 3-6 months later. Language functional MR scannings have shown language functional cortical and subcortical pathway reorganization (in the perilesion or contra-lateral hemisphere) after the operation. All patients returned to a normal socioprofessional life. CONCLUSIONS: By utilizing the dynamic interaction between brain plasticity and fractionated resections, we can totally remove the tumor involving Broca's structure without inducing permanent postoperative deficits and even improve the quality of life.
