ABSTRACT

The co-occurrence of tumor and psycho-cardiological diseases, affecting both the physical and mental aspects of patients, is a common clinical condition that is closely related to tumor treatment and prognosis. Exploring its underlying mechanism and treatment methods can bring new ideas and strategies for clinical treatment. It is believed that heart-kidney yang deficiency is one of the common core mechanisms of psycho-cardiological diseases. Stagnation of heat and toxins is a core mechanism for tumor formation and metastasis. Additionally, cancer and drug toxicity contribute to the development of psycho-cardiological disease by impairing lung circulation. Cancerous toxins can damage the blood vessels, resulting in a diminished vitality in the heart of blood vessels. Simultaneously, lung qi failing in dispersing impairs the downward movement and causes stagnation in the heart of spirit . This process ultimately leads to the development or exacerbation of psycho-cardiological diseases. The author explores the diagnosis and treatment approach based on the “diagnosing and treating diseases according to syndroms” concept, focusing on related syndrom identification and treatment. The process begins with pattern identification, followed by comprehensive analysis of data gained by four diagnostic methods to clearly understand the core pathogenesis and basic treatment principles. After pattern identification, the focus shifts to recognizing the disease and providing additional evidence to support the diagnosis. Special attention is paid to adjusting the use of medication based on the disease's characteristics. This approach aims to achieve precise treatment for tumors and psycho-cardiological diseases, reducing the side effects of multiple medications, therefore to provide guidance for clinical application.

ABSTRACT

Objective:To investigate the application value of outcome-based education (OBE) combined with team-based learning (TBL) in the practice teaching of pediatric emergency and critical care nursing.Methods:A total of 84 nursing students who studied in the pediatric intensive care unit (PICU) of The First Affiliated Hospital of Air Force Medical University were selected and divided into control group and observation group. The 41 nursing students in the control group received traditional teaching, and the 43 nursing students in the observation group received OBE+TBL teaching. The two groups were assessed in terms of theoretical knowledge, practical operation ability, clinical thinking ability, and self-learning ability after teaching, and the degrees of satisfaction with teaching and participation in teaching were compared between the two groups. SPSS 22.0 was used for the t-test and the chi-square test. Results:After teaching, the observation group had significantly better theoretical knowledge, practical operation ability, and self-learning ability than the control group ( P<0.05). Compared with the control group, the observation group had significantly higher scores of learning engagement (recognition, behavior, emotion) ( P<0.05) and satisfaction with classroom effect, knowledge mastery, and learning interest ( P<0.05). Conclusion:The application of OBE+TBL teaching in PICU nursing students can effectively improve their self-learning ability and participation and help them to understand PICU nursing priorities and improve their practical operation ability.

ABSTRACT

Objective To study the wear condition of rotating hinge knee prosthesis (RHKP) during horizontal walking gait, and provide technical references for wear prediction and clinical application of this kind of prosthesis. Methods A finite element wear model of RHKP was established based on the standard ISO 14243, and the simulation results including the wear distribution and mass wear rate of tibiofemoral joint surface were compared with the results from in vitro experiments on the same type of prosthesis. Results The mass wear rate of the polyethylene insert was 26.01 mg/MC (million cycle)from finite element analysis (FEA) and (30.06±1.21) mg/MC from in vitro experiments, and the mass wear rate of the upper surface of polyethene insert from FEA was about 3.3 times that of the lower surface. The wear area obtained by FEA was basically consistent with that obtained by in vitro wear measurement. The main wear area was symmetrically distributed in the middle and back of the upper surface. Conclusions The mass wear rate of RHKP, as a semi-restrictive prosthesis, is obviously higher than that of primary total knee joint prosthesis. More attention should be paid to wear test and evaluation of RHKP.

ABSTRACT

In recent years, due to the wide use of pyrethroid insecticides, the impact of pyrethroid insecticides on human health cannot be ignored. Therefore, how to detect pyrethroid insecticide residues in human body accurately and efficiently has become a research hotspot. However, it is difficult to detect pyrethroid insecticides because of its low residues and fast metabolism. Our article reviewed research on the detection of pyrethroid pesticide residues in human biomaterials in recent years, listed various pretreatment methods and detection methods of different biomaterials in detail, as well as summarized reported limits of detection, limits of quantitation, and recoveries of different methods. Finally, we prospected further development in detection methods of pyrethroid pesticide residues in human biomaterials.

ABSTRACT

China ranks the first in the morbidity and mortality of malignant tumors in the world. Traditional Chinese medicine (TCM) has played a crucial part in preventing recurrence of malignant tumors after surgery, enhancing efficacy and reducing toxicity of radiotherapy and chemotherapy, and promoting the survival of patients with advanced tumors. According to the whole process of tumor occurrence and development and via the long-term clinical practice, we proposed the "deficiency-cold-toxin-blocking-failure evolution theory" of malignant tumors, with depression in the whole process and cancer toxin as the core. The theory is a summary of pathophysiological status at different stages of tumor development based on the disease and syndrome. This paper analyzes the biological basis of the theory. To be specific, we believe that the ''deficiency'' is mainly caused by the tumor immunoediting abnormality and thus the escape of clearance. In addition, the ''cold'' is in line with the metabolic reprogramming of the tumor microenvironment. ''Toxin'' is manifested as the stemness of cancer cells induced by the tumor microenvironment. ''Blocking'' is closely related to the enhanced permeability and retention (EPR) effect of tumor neovasculature. ''Failure'' is exactly the cachexia caused by change of dominant metabolism. ''Depression'' is essentially stress-the accelerated progress of the neuroendocrine system. In combination with clinical practice, we conclude that method of reinforcing healthy Qi and adjusting the balance can help recover tumor immunoediting and restore the immunity to regulate the "deficiency". Moreover, replenishing Qi and warming Yang can correct the tumor metabolic programming to avoid "cold". Removing toxin and reinforcing healthy Qi can reverse tumor cell stemness and thus suppress the ''toxin''. Eliminating the ''blocking'' source can suppress tumor angiogenesis and help regulate the EPR. Regulating Yin and Yang will help relieve the change of dominant metabolism and futile cycle to avoid ''failure''. The method of relieving depression and regulating Qi can relieve neuroendocrine stress and prevent tumor progression, thus alleviating the "depression". Moreover, effect of these methods was tested with effective formulas. This study is expected to lay a foundation for the establishment of a new system for the clinical prevention and treatment of malignant tumors.

ABSTRACT

Pyroptosis is an atypical mode of cell programmed death, which is mainly manifested by pore formation, cell expansion, cell fluid outflow, secretion of inflammatory factors causing inflammatory response, and ultimately leading to cell disintegration after various external stimuli. Pyroptosis was first found in infectious diseases, but later found in the nervous system and cardiovascular system. Recent studies have also found that pyroptosis exists in tumors. It has become one of the hot research topics to explore its role in tumors. At present, studies have proposed that anti-cancer drugs, Chinese medicine monomers and so on can induce the pyroptosis of cancer cells. Therefore, this paper explores the impact molecules related to tumor cell pyroptosis, and summarizes its effect, then proposes two possible new strategies of preventing chemoresistance and regulating metabolic molecules.

ABSTRACT

Tocilizumab has been reported to attenuate the "cytokine storm" in COVID-19 patients. We attempted to verify the effectiveness and safety of tocilizumab therapy in COVID-19 and identify patients most likely to benefit from this treatment. We conducted a randomized, controlled, open-label multicenter trial among COVID-19 patients. The patients were randomly assigned in a 1:1 ratio to receive either tocilizumab in addition to standard care or standard care alone. The cure rate, changes of oxygen saturation and interference, and inflammation biomarkers were observed. Thirty-three patients were randomized to the tocilizumab group, and 32 patients to the control group. The cure rate in the tocilizumab group was higher than that in the control group, but the difference was not statistically significant (94.12% vs. 87.10%, rate difference 95% CI-7.19%-21.23%, P = 0.4133). The improvement in hypoxia for the tocilizumab group was higher from day 4 onward and statistically significant from day 12 (P = 0.0359). In moderate disease patients with bilateral pulmonary lesions, the hypoxia ameliorated earlier after tocilizumab treatment, and less patients (1/12, 8.33%) needed an increase of inhaled oxygen concentration compared with the controls (4/6, 66.67%; rate difference 95% CI-99.17% to-17.50%, P = 0.0217). No severe adverse events occurred. More mild temporary adverse events were recorded in tocilizumab recipients (20/34, 58.82%) than the controls (4/31, 12.90%). Tocilizumab can improve hypoxia without unacceptable side effect profile and significant influences on the time virus load becomes negative. For patients with bilateral pulmonary lesions and elevated IL-6 levels, tocilizumab could be recommended to improve outcome.

ABSTRACT

Objective:To explore the differences of immune reconstitution between peripheral blood stem cell transplantation and umbilical cord blood transplantation.Methods:A total of 300 patients (aged 18 (8, 33), 163 males and 137 females) with malignant hematological diseases who received allogeneic hematopoietic stem cell transplantation in the First Affiliated Hospital of University of Science and Technology of China from January 2018 to March 2020 were enrolled in this study, including 255 cases of umbilical cord blood transplantation and 45 cases of peripheral blood stem cell transplantation. Multicolor flow cytometry was applied to analyze lymphocyte subsets of the percentages and absolute counts in the two donor types and peripheral blood of patients after receiving hematopoietic stem cell transplantation. The differences between the two grafts were compared, and the lymphocyte subsets results were evaluated at 1, 2, 3, 4, 6, 9, 12, and 18 months after transplantation. 18-month disease-free survival (DFS) within the 300 patients under the two transplantation types were retrospectively analyzed.Results:1. The proportion of NKT cells in peripheral blood group was significantly higher than that in cord blood group (2.79% vs 0.24%, P<0.001). 2. The proportion of helper T cells in the UCBT group was higher than that in the PBSCT group, as well as the counts 6 months after transplantation ( P<0.05). 3. The proportion of NK1 cells (3 rd to 9 th month) and count (4 th to 12 th month) in UCBT group were significantly higher than those in PBSCT group ( P<0.05). 4. NKT cells in the UCBT group were lower than those in the PBSCT group (proportion and count) throughout the monitoring process ( P≤0.001). 5. The proportion of DNT cells (within 1 year) and count (within 6 months) in the UCBT group were significantly lower than those in the PBSCT group ( P<0.05). Conclusions:Compared with the peripheral blood stem cell transplantation group, the umbilical cord blood transplantation patients had a faster rate of lymphocyte reconstitution, and patients received umbilical cord blood transplantation had a stronger ability of immune reconstitution and could achieve long-term hematopoiesis.

ABSTRACT

Objective:To explore the feasibility and efficacy of umbilical cord blood transplantation (UCBT) in the treatment of paroxysmal nocturnal hemoglobinuria (PNH).Methods:From May 2014 to December 2019, clinical data were retrospectively reviewed for 7 PNH patients undergoing UCBT. The grades were severe ( n=6) and extremely severe ( n=1). The causes were primary PNH ( n=4) and PNH-aplastic anemia (AA) syndrome ( n=3). There were 5 males and 2 females with a median age of 29 (20-47) years, a median weight of 60(50-71) kg and a median time from diagnosis to transplantation of 62.5(7.7-171) months. All of them were accompanied by transfusion dependence. Myeloablative ( n=6) and reduced-intensity ( n=1) pretreatment was offered. The regimen of preventing GVHD was cyclosporine A plus short-term mycophenolate mofetil without ATG. The median number of input nucleated cells was 2.4(1.71-4.28)×10 7/kg and the median number of CD34+ cells 1.58(0.88-3.02)×10 5/kg. Results:Neutrophil and erythroid engraftment was obtained with a median neutrophil engraftment time of 17(15-21) days and a median erythroid engraftment time of 27. Engraftment time of 37(25-101) days for platelets >20×10 9/L and 62(27-157) days for platelets >50×10 9/L. The incidence of 100-day acute GVHD was 28.6%(95%CI 0-55.3%). The severity of GVHD was grade Ⅱ° acute ( n=2) and mild ( n=1). The median follow-up period was 13.5(3-71.4) months. Six patients survived while another with PNH-AA syndrome with iron overload died of gastrointestinal hemorrhage. The 2-year overall survival rate was 83.3%(95%CI 27.3-97.5%). Conclusions:With excellent engraftment and survival in the treatment of PNH, UCBT is indicated for patients without HLA full-match donor. PNH-AA syndrome with iron overload may be one of the important prognostic factors.

ABSTRACT

OBJECTIVE@#To explore the effect of HNF1A-AS1 on the proliferation, migration and invasion of IL-6-induced hemangioendothelial cells (HemEC) and possible mechanism.@*METHODS@#RT-qPCR was used to detect the expression level of HNF1A-AS1 and miR-363-3p in the tumor tissue and adjacent normal skin tissue from 35 patients with hemangioma. Pearson correlation was used to analyze the correlation between the expression of HNF1A-AS1 and miR-363-3p in tumor tissues. HemEC were isolated and cultured in vitro.Dual luciferase reporter gene experiment was used to study the regulatory effect between HNF1A-AS1 and miR-363-3p. IL-6 was added to HemEC transfected with si-NC, si-HNF1A-AS1, si-HNF1A-AS1 and anti-miR-NC, or si-HNF1A-AS1 and anti-miR-363-3p, respectively. CCK-8 method and clone formation experiment were used to detect cell proliferation in each group. Transwell method was used to detect cell migration and invasion in each group. Western blotting was used to detect the expression of Ki67, MMP-2 and MMP-9 proteins in each group.@*RESULTS@#Compared with normal skin tissues, the expression of IL-6 mRNA in hemangioma tissues was increased (P<0.05), and the expression of IL-6 mRNA in the proliferative phase was lower than that in the degenerative phase (P<0.05). Expression of HNF1A-AS1 in hemangioma tissue was increased (P<0.05), while that of miR-363-3p was decreased (P<0.05), and the two were negatively correlated (r=-0.758, P<0.05). HNF1A-AS1 down-regulated the expression of miR-363-3p in HemEC.IL-6 promoted the expression of HNF1A-AS1, OD value, number of colonies, number of migration and invasion of HemEC cells, and the expression of Ki67, MMP-2 and MMP-9proteins (P<0.05), while reduced the expression of miR-363-3p (P<0.05). Down-regulating si-HNF1A-AS1 reduced the IL-6-induced HemEC cell OD value, colony numbers, migration and invasion and the expression of Ki67, MMP-2 and MMP-9 proteins (P<0.05). Down-regulating miR-363-3p attenuated the inhibitory effect of down-regulating si-HNF1A-AS1 on the proliferation, migration and invasion of HemEC cells induced by IL-6 (P<0.05).@*CONCLUSION@#Expression of HNF1A-AS1 is increased in hemangioma tissues. Down-regulating HNF1A-AS1 may inhibit proliferation, migration and invasion of IL-6-induced hemangioma endothelial cells by targeted up-regulation of miR-363-3p.

ABSTRACT

OBJECTIVE@#To explore the mechanism of @*METHODS@#Healthy male DBA/1 mice were used for CIA modeling. Twenty-five CIA mice with successful modeling and similar arthritis index (AI) scores were randomized equally into model group (CIA), methotrexate (MTX) group, and low-, medium-, and high-dose XWGD groups (0.975, 1.95, and 3.9 g/mL, respectively), with another 5 normal mice as the normal control group. The mice in normal control and CIA groups were given saline once a day, those in MTX group were given 0.1 mg/mL MTX once a week, and those in XWGD groups were treated daily via garage of XWGD containing crude drugs of different doses for 28 consecutive days. The AI score and HE staining were used to evaluate the changes in the joints of the CIA mice. The effect of XWGD on Th1, Th17, MDSC, G-MDSC and M-MDSC cells were evaluated with flow cytometry.@*RESULTS@#Treatment with MTX and different doses of XWGD significantly decreased the AI score of the mice and relieved joint inflammation as compared with the model group (@*CONCLUSIONS@#XWGD can improve joint inflammation in CIA mice by increasing the percentages of G-MDSC cells and decreasing the percentages of M-MDSC, Th1 and Th17 cells, and a high dose of XWGD can produce an equivalent therapeutic effect to methotrexate but with better safety.

ABSTRACT

The past few years have witnessed enormous progresses in the development of antibody-drug conju-gates (ADCs). Consequently, comprehensive analysis of ADCs in biological systems is critical in sup-porting discovery, development and evaluation of these agents. Liquid chromatography-mass spectrometry (LC-MS) has emerged as a promising and versatile tool for ADC analysis across a wide range of scenarios, owing to its multiplexing ability, rapid method development, as well as the capability of analyzing a variety of targets ranging from small-molecule payloads to the intact protein with a high, molecular resolution. However, despite this tremendous potential, challenges persist due to the high complexity in both the ADC molecules and the related biological systems. This review summarizes the up-to-date LC-MS-based strategies in ADC analysis and discusses the challenges and opportunities in this rapidly-evolving field.

ABSTRACT

Objective To evaluate the effect of pretransplant iron overload on the clinical efficacy of allogeneic hematopoietic stem cell transplantation (allo-HSCT) in patients with severe aplastic anemia (SAA). Methods Clinical data of 80 SAA recipients who underwent allo-HSCT for the first time were retrospectively analyzed. According to the incidence of iron overload, all recipients were divided into the iron overload group (n=20) and non-iron overload group (n=60). The engraftment rate, incidence of postoperative complications and clinical prognosis of the recipients afterallo-HSCT were statistically compared between two groups. The influencing factors of 2-year overall survival (OS) and 180 d transplantation related mortality (TRM) were analyzed by Cox proportional hazards regression model. Results The engraftment rate of neutrophils in the non-iron overload group was 98% (59/60), significantly higher than 75% (15/20) in the iron overload group (P < 0.05). The engraftment rate of platelet in the non-iron overload group was 90% (54/60), significantly higher than 65% (13/20) in the iron overload group (P < 0.05). The incidence rate of bloodstream infection in the non-iron overload group was 23% (14/60), remarkably lower than 40% (8/20) in the iron overload group (P < 0.05). The 180 d TRM of the recipients in the non-iron overload group was 17%, significantly lower than 45% in the iron overload group (P < 0.05). The 1- and 2-year OS of the recipients in the non-iron overload group were 82% and 80%, significantly higher than 50% and 44% in the iron overload group (both P < 0.05). Iron overload or not was an independent risk factor of the OS and TRM of the recipients (both P < 0.05). Conclusions Iron overload can affect the OS and TRM of SAA patients after allo-HSCT.

ABSTRACT

Objective To investigate the impact of various distribution of bone cement on the early clinical outcomes in osteoporotic vertebral compression fracture (OVCF) patients treated with percutaneous kyphoplasty (PKP).Methods A total of 312 patients (54 males and 258 females,mean age 69.37 years) who diagnosed as OVCF and received PKP treatment from January 2015 to July 2017 were enrolled in the present study.All subjects were divided into two groups according to different distribution of bone cement:the shaped "O" distribution (group O,113 cases),in which bone cement in the vertebral body presented whole crumb,no separation or loss of bone cement,and the shaped "H" distribution (group H,199 cases),in which bone cement in the vertebral body presented two briquettes,connected with or without a small amount of bone cement.Demographic data,surgical details,radiographic data,and clinical outcomes (at preoperatively,two-days and one-year follow-up) were compared between the two groups.Results There was no significant difference in bone mineral density (BMD),operation duration,blood loss,and occurrence of leakage of bone cement between two groups.In comparison with group O,group H was accompanied with higher volume of injected bone cement and higher proportion of bilateral approach (P<0.05).Both groups achieved significant improvement of VAS scores after surgery,while the group H had a dramatical reduction of VAS scores at one-year follow-up compared with two-days follow-up (P<0.05).In addition,group H had a better restoration of VAS scores at one-year follow-up than group O (P<0.05),though no significant difference was observed at preoperative and two-days follow-up.Both groups achieved significant improvement of radiographic data after surgery (P<0.05) with similar effects of correction.Conclusion Either shaped "H" or shaped"O" distribution of bone cement can obtain satisfied early clinical effects of PKP for the treatment of OVCF.Compared with shaped "O" distribution,shaped "H" distribution can achieve better pain relief at early follow-up.

ABSTRACT

Objective@#To explore the mediating effect of self-efficacy between mindfulness and self-esteem.@*Methods@#In this study, 400 junior school students from a middle school in Jiangxi Province was recruited and complete mindful self scale, general self-efficacy scale and self-esteem scale.@*Results@#The scores of mindfulness, self-efficacy, self-esteem were (63.89±9.12), (22.82±4.83) and (26.14±4.43), respectively. Mindfulness and its four dimensions (self-insight, self-acceptance, self-compassion and non-persistence) were significantly positively correlated with self-esteem (r=0.18-0.53, all P<0.01). Mindfulness and its three dimensions (self-insight, self-compassion and non-persistence) were significantly positively correlated with self-efficacy (r=0.22-0.39, all P<0.01). Self-efficacy and self-esteem were significantly positively correlated (r=0.82, P<0.01). Mindfulness positively predicted self-efficacy (β=0.38, P<0.01), self-efficacy positively predicted self-esteem (β=0.74, P<0.01), and mindfulness positively predicted self-esteem (β=0.25, P<0.01). That was, self-efficacy partially mediated the relationship between mindfulness and self-esteem. The mediating effect value was 0.28, accounting for 52.83% of the total effect.@*Conclusion@#Mindfulness not only directly affects adolescents' self-esteem, but also influences adolescents' self-esteem through self-efficacy.

ABSTRACT

Objective@#To compare the clinical efficacy of umbilical cord blood transplantation (UCBT) and hematopoietic stem cell transplantation from HLA-matched sibling donors (MSD-HSCT) in the treatment of myelodysplastic syndrome-EB (MDS-EB) or acute myeloid leukemia with myelodysplasia-related changes (AML-MRC) .@*Methods@#A cohort of 64 patients (including 38 cases of MDS-EB and 26 cases of AML-MRC) who received UCBT/MSD-HSCT from February 2011 to December 2017 were retrospectively analyzed.@*Results@#①Compared with MSD-HSCT group, UCBT group had a higher proportion of AML-MRC patients [52.8% (19/36) vs 25.0% (7/28) , P=0.025], and a lower median age [13 (1.5-52) years vs 32 (10-57) years, P=0.001]. ②The engraftment of neutrophils both in UCBT and MSD-HSCT groups on +42 d was 100%, and the median engraftment time was 17.5 (11-31) d and 11.5 (10-20) d, respectively. The engraftment of platelet at +100 d in UCBT group was 91.4%, the median engraftment time was 40 (15-96) d; The engraftment of platelet at +100 d in MSD-HSCT group was 100%, and the median engraftment time was 15 (11-43) d. ③There were no statistically significant differences in terms of the cumulative incidence of Ⅱ-Ⅳ and Ⅲ/Ⅳ aGVHD of 100 d and transplant related mortality (TRM) of 180 d, relapse rate, overall survival (OS) , disease-free survival (DFS) between UCBT and MSD-HSCT groups (P>0.05) . ④The 3-year cumulative incidence of chronic GVHD (cGVHD) and severe chronic GVHD in UCBT group were lower than of MSD-HSCT group [28.3% (95%CI 13.4%-45.3%) vs 67.9% (95%CI 46.1%-82.4%) , P=0.002; 10.3% (95%CI 2.5%-24.8%) vs 50.0% (95%CI 30.0%-67.1%) , respectively, P<0.001]. The cumulative 3-year incidence of GVHD-free and relapse-free survival (GRFS) of UCBT group was significantly higher than of MSD-HSCT group [55.0% (95%CI 36.0%-70.6%) vs 28.6% (95%CI 13.5%-45.6%) , P=0.038].@*Conclusion@#UCBT could obtain better quality of life after transplantation than MSD-HSCT in treatment of MDS-EB/AML-MRC.
