ABSTRACT

Objective To investigate the effects of long noncoding RNA H19 on lipid accumulation of macrophages under high fat stress and its mechanism. Methods Human THP-1 cells-derived macrophages were incubated with ox-LDL, and the effects of H19 siRNA intervention on lipid accumulation was observed. The THP-1 cells were divided into control group (conventional culture), ox-LDL group, siRNA negative control (NC siRNA) combined with ox-LDL treatment group, and H19 siRNA combined with ox-LDL treatment group. Oil red O staining was used to determine the lipid accumulation in cells, and cholesterol concentration was analyzed by enzymatic method; ATP assay kit for detecting celluar ATP content; colorimetry was used to detect the levels of oxidative stress indicators and ELISA was used to detect the levels of monocyte chemoattractant protein-1 (MCP-1) in the cell supernatant. Western blot analysis was used to detect the protein expression of ATP binding cassette transporter A1 (ABCA1), peroxisome proliferator-activated receptor α (PPARα), peroxisome proliferator-activated receptor γ coactivator-1α (PGC-1α) and nuclear factor κB p-p65 (NF-κB p-p65). Results Knockdown H19 significantly inhibited intracellular lipid accumulation, decreased total cholesterol (TC) and cholesterol ester (CE) content, and decreased CE/TC ratio. Knockdown H19 significantly alleviated cell damage including an increase in ATP content, a decrease in oxidative stress levels and a decrease in MCP-1 levels, which caused by high-fat stress. H19 siRNA upregulated expression of ABCA1, PPARα and PGC-1α in THP-1 derived macrophages, downregulated NF-κB signal pathway. Conclusion Knockdown H19 upregulates PGC-1α expression in THP-1 cells and downregulates NF-κB pathway, which promotes cholesterol reverse transport, reduces inflammatory reaction and inhibits lipid accumulation.

ABSTRACT

Objective:To explore the therapeutic mechanism of Mongolian medicine Sendeng-4 decoction for rheumatoid arthritis by 99Tc m-hydrazinonicotinamide-(polyethylene glycol) 4-E[(polyethylene glycol) 4-c((Arg-Gly-Asp)fk)] 2 (3PRGD 2) imaging. Methods:A total of 200 female SD rats (age: 6-7 weeks) were divided into collagen-induced arthritis (CIA) group ( n=176) and blank control group ( n=24). Rats in the CIA group were divided into Sendeng-4 decoction treatment group ( n=24), etanercept treatment group ( n=24), and negative control group ( n=24) by simple random sampling method. 99Tc m-3PRGD 2 SPECT/CT imaging was performed before and after modeling and treatment. The differences of target/non-target (T/NT) ratio and serological, pathological, and immunohistochemical results among groups were compared by one-way analysis of variance or Kruskal-Wallis rank sum test. The correlation was analyzed by Pearson correlation or Spearman correlation analysis. Results:There were 95 (95/176) CIA models successfully established. The T/NT ratios of Sendeng-4 decoction treatment group and etanercept treatment group were lower than that of negative control group (0.260± 0.094, 0.238±0.099, 0.766±0.144 ; F=163.00, P<0.001), while there was no significant difference between the two drug treatment groups ( P>0.05). After drug treatment, serum levels of vascular endothelial growth factor (VEGF), tumor necrosis factor-α (TNF-α) and α vβ 3 were significantly lower than those of negative control group ( F values: 49.43-92.36, all P<0.001), pathological score was also lower than that of negative control group ( H=34.25, P<0.001), and levels of immunohistochemical makers (VEGF, TNF-α, α vβ 3, CD31, CD34) were also lower than those of negative control group ( H values: 13.51-26.84, all P<0.001), while there were no significant differences between the two drug treatment groups (all P>0.05). The T/NT ratios were positively correlated with above indictors in Sendeng-4 decoction treatment group ( r values: 0.56-0.59, rs values: 0.49-0.69), etanercept treatment group ( r values: 0.50-0.55, rs values: 0.46-0.70) and negative control group ( r values: 0.55-0.80, rs values: 0.58-0.86, P<0.001 or P<0.05). Conclusion:Verified by 99Tc m-3PRGD 2 SPECT/CT imaging and molecular pathology, Mongolian medicine Sendeng-4 decoction can inhibit neovascularization by down-regulating vascular factors such as VEGF, resulting in delaying the progression of the disease and improving clinical symptoms.

ABSTRACT

Objective:To investigate the effect of chemotherapy combined with sorafenib on the prognosis of FLT3 internal tandem duplication (FLT3-ITD)-positive acute myeloid leukemia and to find a more effective treatment.Methods:The clinical data of 60 patients who were newly diagnosed with acute myeloid leukemia and who received treatment in The Second Affiliated Hospital of Qiqihar Medical University from January 2015 to January 2017 were retrospectively analyzed. The patients were divided into three groups according to whether they were positive for FLT3-ITD and the treatment method they used. The observation group (FLT3-ITD-positive, n = 19) were treated with sorafenib based on routine chemotherapy. The control group 1 (FLT3-ITD-positive, n = 21) was treated only with routine chemotherapy. The control group 2 (FLT3-ITD-negative, n = 20) was treated only with routine chemotherapy. After the first and fourth courses of treatment, clinical efficacy was compared among the three groups. Results:After the first course of treatment, the complete remission rate in control group 2 was 50.0% (10/20), which was significantly higher than 15.8% (3/19) in the observation group and 4.8% (1/21) in the control group 1 ( H = 13.39, P < 0.05). After the fourth course of treatment, the complete remission rate in the observation group, control group 2, and control group 1 was 63.2% (12/19), 60.0% (12/20), and 4.8% (1/21), respectively, and the differences were statistically significant ( H = 19.21, P < 0.05). Four-year follow-up results showed that the median survival time in the observation group, control group 1, and control group 2 was 36.63, 24.15, and 45.00 months respectively. The event-free survival in the observation group, control group 1, and control group 2 was 18.00, 9.82, and 24.90 months, respectively. The median survival time and the event-free survival in the control group 2 were significantly longer than those in the observation group and control group 1 ( χ2 = 19.93, 23.04, both P < 0.001). Conclusion:Chemotherapy combined with sorafenib for treating newly-diagnosed FLT3-ITD-positive acute myeloid leukemia can provide comprehensive benefits and have advantages for survival over chemotherapy without sorafenib and chemotherapy alone.

ABSTRACT

The traditional SPECT has been considered unable to quantitatively analyze due to the limitations of device performance and reconstructing algorithm. Because of the development of SPECT devices, the emergence of SPECT/CT, and the improvement of reconstructive algorithms, SPECT can be used for quantitative analysis like PET. The current quantitative SPECT researches focus on the usefulness of quantitative SPECT technology in clinical diagnosis and the guidance and evaluation of radionuclide therapy. This review summarizes the development of SPECT quantification, the current status of quantitative SPECT researches in clinical diagnosis and radionuclide therapy, as well as the limitations and advantages of SPECT quantification.

ABSTRACT

It is well known that an unhealthy lifestyle is a major risk factor for metabolic diseases, while in recent years, accumulating evidence has demonstrated that the gut microbiome and its metabolites also play a crucial role in the onset and development of many metabolic diseases, including obesity, type 2 diabetes, nonalcoholic fatty liver disease, cardiovascular disease and so on. Numerous microorganisms dwell in the gastrointestinal tract, which is a key interface for energy acquisition and can metabolize dietary nutrients into many bioactive substances, thus acting as a link between the gut microbiome and its host. The gut microbiome is shaped by host genetics, immune responses and dietary factors. The metabolic and immune potential of the gut microbiome determines its significance in host health and diseases. Therefore, targeting the gut microbiome and relevant metabolic pathways would be effective therapeutic treatments for many metabolic diseases in the near future. This review will summarize information about the role of the gut microbiome in organism metabolism and the relationship between gut microbiome-derived metabolites and the pathogenesis of many metabolic diseases. Furthermore, recent advances in improving metabolic diseases by regulating the gut microbiome will be discussed.

ABSTRACT

ObjectiveTo investigate the value of two-dimensional shear wave elastography (2D-SWE) in the noninvasive evaluation of the presence or absence of esophageal varices (EV) in patients with hepatitis B cirrhosis by liver stiffness measurement (LSM) and spleen stiffness measurement (SSM). MethodsA total of 172 patients who were diagnosed with hepatitis B cirrhosis in Beijing Ditan Hospital, Capital Medical University, from April 2019 to February 2020 were enrolled in a prospective study, and according to the results of gastroscopy, they were divided into non-EV group and EV group. The two groups were compared in terms of spleen thickness (ST), spleen diameter (SD), LSM, and SSM. The independent samples t-test was used for comparison of normally distributed continuous data between two groups, and the Mann-Whitney U test was used for comparison of non-normally distributed continuous data between two groups; the chi-square test was used for comparison of categorical data. The receiver operating characteristic (ROC) curve was used to investigate the value of LSM and SSM in the diagnosis of EV, and the Z test was used to compare the diagnostic accuracy of LSM and SSM. ResultsThere were 121 patients in the EV group and 51 patients in the non-EV group. There were significant differences between the two groups in ST (t=8143, P<0.001), SD (t=7.363, P<0.001), LSM (Z=3.024, P=0.002), SSM (t=15.142, P<0.001), and presence or absence of ascites (χ2=22.101, P<0.001). LSM had an area under the ROC curve (AUC) of 0.646 (95% confidence interval [CI]: 0570-0.718) in the diagnosis of EV, with a sensitivity (Se) of 83.47%, a specificity (Sp) of 47.06%, a positive predictive value (PPV) of 78.9%, and a negative predictive value (NPV) of 54.5% at the optimal cut-off value of 13.16. SSM had an AUC of 0.951 (95% CI: 0.907-0.978) in the diagnosis of EV, with an Se of 80.99%, an Sp of 96.08%, a PPV of 98.0%, and an NPV of 68.1% at the optimal cut-off value of 38.08. SSM had a better diagnostic accuracy than LSM (Z=6.096, P<0.001). ConclusionLSM and SSM can be used to predict the presence or absence of EV in patients with hepatitis B cirrhosis. SSM has a higher accuracy than LSM and can provide accurate diagnostic information for clinical practice.

ABSTRACT

Background The increasing threats of air pollution and extreme weather have been widely recognized in recent years in China, but their individual and joint effects on cardio-cerebrovascular mortality are unclear. Objective This study aims to investigate the individual effects of and potential interactions between oxidant pollutants and ambient temperature on cardio-cerebrovascular mortality risks. Methods We collected daily data on death counts of cardio-cerebrovascular diseases, concentrations of ambient air pollutants, and meteorological parameters in Guangzhou, Chinabetween 1 January 2006 and 31 December 2016. A generalized additive model with a Poisson distribution was conducted to assess the associations of oxidant pollutants and ambient temperature with cardio-cerebrovascular mortality risks. Bivariate response surface models and stratified analyses were further adopted to qualitatively and quantitatively examine the potential interactions between oxidant pollutants and ambient temperature on cardio-cerebrovascular mortality risks. Results During the study period, the daily averages were 60.3 μg·m−3 for ozone (O3), 50.9 μg·m−3 for combined atmospheric oxidant capacity (Ox), 32.5 μg·m−3 for nitrogen dioxide (NO2), and 22.3℃ for ambient temperature. The average daily death counts of coronary and stroke diseases were 20 and 15, respectively. Per 10 μg·m−3 increment in O3, Ox, and NO2 were associated with increased coronary mortality risks (excess risk, ER) of 1.26% (95%CI: 0.79%-1.74%), 1.61% (95%CI: 0.99%-2.23%), and 1.33% (95%CI: 0.59%-2.07%), and with increased stroke mortality risks of 1.56% (95%CI: 1.04%-2.09%), 2.30% (95%CI: 1.60%-3.01%), and 2.93% (95%CI: 2.07%-3.79%) over cumulative lags of 2-5 days, respectively. The exposure-response relationships between ambient temperature and coronary and stroke mortality risks exhibited an inverse "J" shape, with the minimum mortality at temperatures of 25.7℃ for coronary disease and 27.3℃ for stroke. Our results further showed potentially synergic effects of higher temperatures and higher levels of O3 and Ox exposures on coronary mortality risks, and the relative ER due to interactions was 0.103 (95%CI: 0.028-0.178) for O3 and 0.079 (95%CI: 0.004-0.154) for Ox. We didn't find evidence of an interaction between oxidant pollutants and low temperature. Conclusion Short-term exposures to oxidant pollutants are associated with increased cardio-cerebrovascular mortality risks, and the interactive effects of high temperature and oxidant pollutants are synergistic in relation to cardio-cerebrovascular mortality risks.

ABSTRACT

【Objective】 To estimate the application value of washed red blood cells (RBC) in perioperative patients with liver cancer. 【Methods】 86 perioperative patients with liver cancer who met the inclusion/exclusion criteria were divided into observation group (n=42) and control group (n=44). In the observation group, 22 patients were transfused with RBC and 20 with washed RBC. Patients without RBC transfusion worked as the controls. The name of disease, tumor stage, tumor size, Hb before and after blood transfusion, transfusion volume and blood components, adverse reaction to blood transfusion, operation time and blood loss during surgery, systemic infection, tumor recurrence and metastasis, and survival time were recorded. Blood transfusion efficacy, survival time, adverse reaction to blood transfusion, tumor recurrence and metastasis among these groups were compared. 【Results】 Among the non-transfusion group, washed RBC group and RBC group, the Hb(g/L)were 93.9±16.5 vs 80.4±24.5 vs 74.7±26.1, operative time (h) 2.8±0.7 vs 4.3±1.6 vs 3.9±2.0, operative blood loss(mL) 291.0±0.3 vs 388.0±165.8 vs 466.3±198.4 respectively before blood transfusion (all P0.05). There were significant differences in tumor metastasis (50% vs 43%) and recurrence (50% vs 43.1%) between blood transfusion group and non-blood transfusion group (P0.05). The nosocomial infection rate in washed RBC group (36%) was significantly lower that that in RBC group (88.6%) and non-transfusion group (50%) (P<0.05). 【Conclusion】 Blood transfusion caused by hypoxia may increase tumor metastasis and recurrence in perioperative patients with liver cancer. Transfusion of washed RBC can achieve the curative effect and reduce adverse reactions to blood transfusion, but has no significant impact on the survival time.

ABSTRACT

Objective:To compare the quantitative parameters of myocardial blood flow based on SPECT imaging and those determined by PET imaging in coronary microvascular disease (CMVD) animal models, in order to clarify the accuracy and feasibility of SPECT quantitative analysis in CMVD.Methods:Seven Saanen milk goats (either male or female; (20±5) kg), were selected for establishing CMVD animal models by microsphere embolization. Dynamic myocardial perfusion imaging (DMPI) with one-day method of resting + ATP stress 99Tc m-methoxyisobutylisonitrile (MIBI) SPECT was performed before and after the modeling, respectively. One-day method of resting + ATP stress 13N-ammonia PET DMPI was performed after the modeling. The quantitative parameters determined by SPECT and PET after the modeling, including stress myocardial blood flow (SMBF), resting myocardial blood flow (RMBF) and myocardial flow reserve (MFR), were compared by paired t test. Parameters based on SPECT after modeling were compared with those of baseline levels. Bland-Altman analysis was applied to access the agreement between SPECT and PET. Results:Four of the seven experimental goats were fully imaged. The RMBF(ml·g -1·min -1; 1.52±0.27 vs 1.29±0.20), SMBF(ml·g -1·min -1; 0.74±0.19 vs 0.99±0.26), and MFR (0.53±0.16 vs 0.76±0.10) of the left ventricle (global) obtained by SPECT and PET in CMVD models were not significantly different ( t values: 3.121, 1.195, 1.930, all P>0.05). Among left anterior descending branch (LAD), left circumflex (LCX) and right coronary artery (RCA), the RMBF, SMBF and MFR values quantified by SPECT and PET were neither statistically significant ( t values: 0.182-2.734, all P>0.05). Bland-Altman analysis showed the quantitative parameters measured by SPECT and PET DMPI in left ventricle, LAD, LCX, RCA had a good consistency. The difference between the two methods for determining RMBF was up to 0.63 ml·g -1·min -1, and that of SMBF was up to 0.66 ml·g -1·min -1. All points are within the 95% confidence limit; MFR differs at most by 0.56, and 14/16 points were within 95% confidence limit. The RMBF (ml·g -1·min -1) of left ventricle measured by SPECT after modeling was not significantly different from that before modeling (1.52±0.27 vs 1.57±0.36; t=0.166, P>0.05); the SMBF (ml·g -1·min -1) and MFR after modeling were significantly lower than those before modeling (0.74±0.19 vs 2.34±0.89, 0.53±0.16 vs 1.39±0.31, t values: 3.836, 6.309, both P<0.05). Similar results were found when comparing the parameters of LAD/LCX/RCA after modeling with those before modeling (RMBF t values: 0.191, 0.235, 0.195, all P>0.05; SMBF/MFR t values: 0.411-19.911, all P<0.05). Conclusion:The blood flow quantitative parameters measured by SPECT imaging have a good consistency with those based on PET imaging, and the myocardial blood flow quantitative analysis of SPECT can evaluate the blood flow perfusion of CMVD.

ABSTRACT

Objective:To study the effect of spleen and marrow strengthening method combined with CAG regimen on the quality of life(QOL) of elderly patients with acute myeloid leukemia with spleen-kidney Yang deficiency syndrome.Methods:From June 2017 to October 2018, 50 elderly patients with acute myeloid leukemia with spleen-kidney Yang deficiency were randomly divided into treatment group and control group by random number table method, with 25 patients in each group.The patients in the control group were treated with CAG regimen(Ara-C+ Acla+ G-CSF), while the patients in the treatment group were treated with CAG regimen and leukemia prescription I, which was the empirical prescription for spleen and kidney Yang deficiency syndrome in elderly patients with acute myeloid leukemia.The patients were treated for two courses.The traditional Chinese medicine (TCM) syndromes and QOL scores of patients in two groups were compared and observed.Results:Before treatment, there was no statistically significant difference in the score of TCM syndromes between the two groups ( P>0.05). After treatment, the improvement of TCM syndromes in the treatment group had statistically significant difference compared with before treatment[before treatment (9.29±4.22)points, after treatment (5.04±3.83)points, t=3.656, P=0.001], but that in the control group had no statistically significant difference ( P>0.05). The treatment group was better than the control group ( t=-2.081, P=0.044). The total effective rate of the treatment group was 58.33% (14/24), which was significantly higher than that of the control group[26.32% (5/19)], and the difference was statistically significant (χ 2=5.831, P<0.05). Before treatment, there was no statistically significant difference in the total score of QOL between the two groups ( P>0.05). After treatment, the scores of QOL in both two groups were improved, the differences were statistically significant[the control group: (40.37±2.93)points vs.(38.21±2.76)points, t=2.337, P=0.025; the treatment group: (41.46±2.57)points vs.(36.54±2.34)points, t=6.929, P=0.000], and the QOL score of the treatment group was better than that of the control group ( t=-2.145, P=0.038). Conclusion:The improvement of TCM syndromes and QOL of elderly patients with acute myeloid leukemia with spleen-kidney Yang deficiency syndrome treated by spleen and marrow strengthening method combined with CAG regimen is better than that treated by CAG chemotherapy alone.

ABSTRACT

Multiple system atrophy (MSA) is a sporadic neurodegenerative disease with insidious onset, and relatively rapid progress in adult. MSA patients may be admitted to different departments of hospital several years before the full manifestation of motor symptoms, because of various non-motor symptoms such as urinary disorders, sexual dysfunction, orthostatic hypotension, psychic symptoms and sleep disorders. This may delay the diagnosis and treatment of MSA. The review is to improve the understanding of the non-motor symptoms of MSA, which may help to reach more accurate diagnosis and better treatment, and improve the quality of life of patients with MSA.

Methods:Sixty female Wistar rats were divided into control group ( n=10; injected with saline of 0.3 ml/piece) and collagen-induced arthritis (CIA) group ( n=50; injected with type Ⅱ collagen emulsion of 0.3 ml/piece). Rats in 2 groups were subjected to 99Tc m-3PRGD 2 planar imaging before modeling, 25 and 45 d after modeling. The changes of the target/non-target ratio (T/NT) of the lesion joint and mediastinum before and after modeling were measured and analyzed in CIA rats, and compared with rats in control group. Pathological examination was conducted. Repeated measures analysis of variance and independent-sample t test were used to analyze the data. Results:Thirty-two rats in CIA group were successfully established, and obvious synovitis and synovial thickening, neovascularization were observed in the images. The T/NT of diseased joints in CIA group before modeling, 25 and 45 d after modeling were 0.158±0.023, 0.402±0.144, and 0.705±0.163 ( F=286.924, P<0.01). The T/NT of diseased joints at 25 and 45 d after modeling were significantly different from those of control group (0.160±0.028 and 0.158±0.032; t values: -10.484 and -20.917, both P<0.01). Immunohistochemistry results showed positive expressions of vascular endothelial growth factor, α vβ 3 and tumor necrosis factor-α in the synovial tissue in of diseased joints in rats of CIA group. Conclusion:99Tc m-3PRGD 2 has high sensitivity for joint synovial neovascularization in rat rheumatoid arthritis models and is expected to be used for early diagnosis of RA.

ABSTRACT

Since metabolic process differs between humans and mice, studies were performed in hamsters, which are generally considered to be a more appropriate animal model for studies of obesity-related metabolic disorders. The modulation of gut microbiota, bile acids and the farnesoid X receptor (FXR) axis is correlated with obesity-induced insulin resistance and hepatic steatosis in mice. However, the interactions among the gut microbiota, bile acids and FXR in metabolic disorders remained largely unexplored in hamsters. In the current study, hamsters fed a 60% high-fat diet (HFD) were administered vehicle or an antibiotic cocktail by gavage twice a week for four weeks. Antibiotic treatment alleviated HFD-induced glucose intolerance, hepatic steatosis and inflammation accompanied with decreased hepatic lipogenesis and elevated thermogenesis in subcutaneous white adipose tissue (sWAT). In the livers of antibiotic-treated hamsters, cytochrome P450 family 7 subfamily B member 1 (CYP7B1) in the alternative bile acid synthesis pathway was upregulated, contributing to a more hydrophilic bile acid profile with increased tauro--muricholic acid (TMCA). The intestinal FXR signaling was suppressed but remained unchanged in the liver. This study is of potential translational significance in determining the role of gut microbiota-mediated bile acid metabolism in modulating diet-induced glucose intolerance and hepatic steatosis in the hamster.
