摘要
OBJECTIVE@#To explore the role of a new blood-based, multiomics and multidimensional method for evaluating the efficacy of patients with lymphoma.@*METHODS@#10 ml peripheral blood was extracted from each patient, and the genomic copy number aberrations (CNA) and fragment size (FS) were evaluated by low-depth whole genome sequencing of cfDNA, and the level of a group of plasma tumor marker (PTM) were detected at the same time. The cancer efficacy score (CES) was obtained by standardized transformation of the value of above three numerical indexes, and the changes of CES before and after treatment were compared to evaluate the patient's response to the treatment regimen.@*RESULTS@#A total of 35 patients' baseline data were collected, of which 23 cases (65.7%) had elevated CES values. 18 patients underwent the first time test. The results showed that the CES value of 9 patients with positive baseline CES decreased significantly at the first test, and the efficacy evaluation was PR, which was highly consistent with the imaging evaluation results of the same period. At the same time, the CNA variation spectrum of all patients were evaluated and it was found that 23 patients had partial amplification or deletion of chromosome fragments. The most common amplification site was 8q24.21, which contains important oncogenes such as MYC. The most common deletion sites were 1p36.32, 4q21.23, 6q21, 6q27, 14q32.33, and tumor suppressor-related genes such as PRDM1, ATG5, AIM1, FOXO3 and HACE1 were expressed in the above regions, so these deletions may be related to the occurrence and development of lymphoma.@*CONCLUSION@#With the advantages of more convenience, sensitivity and non-invasive, this multiomics and multidimensional efficacy detection method can evaluate the tumor load of patients with lymphoma at the molecular level, and make more accurate efficacy evaluation, which is expected to serve the clinic better.

Objective: To investigate the effect of nuclear factor erythroid 2-related factor 2 (Nrf2) in the alteration of tight junction protein expression in choroid plexus epithelial cells created by lanthanum-activated matrix metalloproteinase 9 (MMP9) . Methods: In October 2020, immortalized rat choroid plexus epithelial cell line (Z310) cells were used as the blood-cerebrospinal fluid barrier in vitro, and were divided into control group and 0.125, 0.25, 0.5 mmol/L lanthanum chloride (LaCl(3)) treatment group. After treating Z310 cells with different concentrations of LaCl(3) for 24 hours, the morphological changes of Z310 cells were observed under inverted microscope, the protein expression levels of MMP9, occludin and zonula occludens-1 (ZO-1) were observed by cellular immunofluorescence method, and the protein expression levels of MMP9, tissue inhibitors of metalloproteinase1 (TIMP1) , occludin, ZO-1 and Nrf2 were detected by Western blotting. The level of reactive oxygen species (ROS) in cells was detected by flow cytometry. Results: Compared with the control group, Z310 cells in the LaCl(3) treatment group were smaller in size, with fewer intercellular junctions, and more dead cells and cell fragments. The expression level of MMP9 protein in cells treated with 0.25 and 0.5 mmol/L LaCl(3) was significantly higher than that in the control group (P<0.05) , and the expression level of TIMP1 and tight junction proteins occudin and ZO-1 was significantly lower than that in the control group (P<0.05) . Compared with the control group, the ROS production level in the 0.25, 0.5 mmol/L LaCl(3) treatment group was significantly increased (P<0.05) , and the Nrf2 protein expression level in the 0.125, 0.25, 0.5 mmol/L LaCl(3) treatment group was significantly decreased (P<0.05) . Conclusion: Lanthanum may increase the level of ROS in cells by down regulating the expression of Nrf2, thus activating MMP9 to reduce the expression level of intercellular tight junction proteins occludin and ZO-1.

Objective:To develop a short-term prognostic model of spontaneous cerebral hemorrhage based on eXtreme Gradient Boosting (XGBoost) machine learning, and to compare its predictive performance with a Logistic regression model.Methods:Patients with sICH admitted to Department of Neurology, Second People's Hospital of Hefei from January 2018 to March 2022 were chosen; their general demographic characteristics, medical history, laboratory indices and cranial imaging data were retrospectively collected. The prognoses of patients 90 d after discharge were evaluated according to modified Rankin Scale (mRS) scores (good prognosis: mRS scores<3; poor prognosis: mRS scores≥3). XGboost and multiple Logistic regression models were used to screen out the factors for prognoses of patients 90 d after discharge, and area under receiver operating characteristic (ROC) curves, sensitivity, specificity and prediction accuracy of the 2 models were analyzed and compared.Results:A total of 413 patients with sICH were included; 180 patients(43.6 %) had poor prognosis and 233 (56.4%) had good prognosis 90 d after discharge. Multivariate Logistic regression results showed that age≥65 years, hemorrhage into the ventricle, hematoma volume of 20-40 mL, hematoma volume>40 mL and National Institutes of Health Stroke Scale (NIHSS) scores were independent influencing factors for short-term prognoses of sICH ( P<0.05). The variables in the XGBoost model were ranked in order of importance: NIHSS scores, systolic blood pressure at admission, Glasgow coma scale (GCS) scores, age≥65 years, hemorrhage into the ventricle, hematoma volume of 20-40 mL, and hematoma volume>40 mL. AUC of XGBoost model in predicting the prognosis was 0.895 (95% CI: 0.820-0.947), enjoying sensitivity of 68.89%, specificity of 94.83%, and prediction accuracy of 83.5%. AUC of Logistic regression model in predicting the prognosis was 0.894 (95% CI: 0.818-0.946), enjoying sensitivity of 93.33%, specificity of 70.69%, and prediction accuracy of 80.58%. Conclusion:The short-term prognostic model based on XGboost for sICH patients has high predictive efficacy, whose predictive accuracy is better than traditional Logistic regression.

Malignant liver tumors have a high incidence and mortality rate. Therefore, it is of great significance to promptly learn about tumor advancement status through relevant examinations for patients' follow-up, diagnosis, and therapy as well as the improvement of the five-year survival rate. The primary lesions and intrahepatic metastases of malignant liver tumors have been better demonstrated in the clinical study with the use of various isotope-labeled fibroblast activating protein inhibitors because of their low uptake in liver tissues and high tumor/background ratio, which provides a new method for early diagnosis, precise staging, and radionuclide therapy. In light of this context, a review of the research progress of fibroblast-activating protein inhibitors for the diagnosis of liver malignant tumors is presented.

ObjectiveTo explore the role of transient receptor potential vanilloid 1 (TRPV1) channel in reducing cardiomyocyte toxicity of Aconiti Kusnezoffii Radix processed with Chebulae Fructus. MethodH9c2 cardiomyocytes cultured in vitro were used as a model to assess cell viability by methyl thiazolyl tetrazolium (MTT) assay, the expression of TRPV1 mRNA was detected by real-time fluorescence quantitative polymerase chain reaction (Real-time PCR), and the leakage rate of lactate dehydrogenase (LDH), the changes of nucleus, reactive oxygen species (ROS), mitochondrial membrane potential and Ca2+ contents were detected by enzyme linked immunosorbent assay (ELISA). ResultCompared with the blank group, when the concentration was ≥0.5 g·L-1, the cell viability was significantly decreased (P<0.01), the leakage rate of LDH, the release of ROS and Ca2+ were increased, the mitochondrial membrane potential was decreased, and the nucleus was pyknosis or even broken in raw Aconiti Kusnezoffii Radix and Aconiti Kusnezoffii Radix processed with Chebulae Fructus groups. When the concentration was ≥0.5 g·L-1, compared with the same mass concentration of raw Aconiti Kusnezoffii Radix group, the cell viability increased significantly (P<0.01), the leakage rate of LDH, the release of ROS and Ca2+ decreased, the mitochondrial membrane potential increased, and the nuclear morphology improved in Aconiti Kusnezoffii Radix processed with Chebulae Fructus group. Application of the same mass concentration of raw Aconiti Kusnezoffii Radix to H9c2 cardiomyocytes pretreated with the TRPV1 inhibitor BCTC significantly increased cell viability, decreased leakage rate of LDH, ROS and Ca2+ release, increased mitochondrial membrane potential and improved nuclear pyknosis compared with untreated H9c2 cardiomyocytes. Application of the same mass concentration of Aconiti Kusnezoffii Radix processed with Chebulae Fructus to H9c2 cardiomyocytes pretreated with BCTC decreased cell viability, increased LDH leakage rate, ROS and Ca2+ release, reduced mitochondrial membrane potential compared with untreated H9c2 cardiomyocytes. Real-time PCR results showed that both raw Aconiti Kusnezoffii Radix and Chebulae Fructus decoction could increase the expression of TRPV1 mRNA in cardiomyocytes in a concentration dependent manner. ConclusionRaw Aconiti Kusnezoffii Radix can induce cardiomyocyte apoptosis and cardiotoxicity by activating TRPV1 channel, while Aconiti Kusnezoffii Radix processed with Chebulae Fructus can attenuate the toxicity through TRPV1 channel, which may be related to the synergistic effect of acid components in Chebulae Fructus and alkaloids in Aconiti Kusnezoffii Radix on TRPV1 channel.
摘要
Natural product bufotenine (5) which could be isolated from Venenum Bufonis, has been widely used as a tool in central nervous system (CNS) studies. We present here its quaternary ammonium salt (6) which was synthesized with high yields using 5-benzyloxyindole as raw materials, and we firstly discover its analgesic effects in vivo. The analgesic evaluation showed that compounds 5 and 6 had stronger effects on the behavior of formalin induced pain in mice. Moreover, the combination of compound 6 and morphine has a synergistic effect. We intended to explain the molecular mechanism of this effect. Therefore, 36 analgesic-related targets (including 15 G protein-coupled receptors, 6 enzymes, 13 ion channels, and 2 others) were systemically evaluated using reverse docking. The results indicate that bufotenine and its derivatives are closely related to acetyl cholinesterase (AChE) or α

Objective:To explore the effect of Huangjingwan (HW) on the expressions of Wnt/β-catenin signal pathway-associated proteins in the hippocampus of mice with Alzheimer's disease (AD) induced by D-galactose and okadaic acid with learning and memory disorders, as well as its mechanism. Method:After subcutaneous injection with 1.0% D-galactose (0.14 g·kg-1·d-1) into the back and neck of mice for 4 weeks, the right ventricle of mice was injected with 2 μL(75 ng) of okadaic acid for one time to make AD model, and the successfully modeled AD mice were selected by Morris water maze. Then, the selected AD mice were randomly divided into AD model group, memantine group (1.3×10-3 g·kg-1·d-1) and HW group (2.5 g·kg-1·d-1). In addition, the sham model control group and the normal control group were set up. At the same time, 2 μL normal saline was injected into the right ventricle of mouse in the sham model control group as the modeling control. Two weeks after molding, the mice in the two experimental drug groups were given the corresponding dose of the experimental drug by gavage for 4 weeks. In addition, after 2 weeks of AD modeling, mice in sham model control group and AD model group were intragastrically administrated with the same amount of normal saline daily for 4 weeks. There was no special treatment in the normal control group. At the end of gavage, the shuttle experiment was performed to detect the differences in learning and memory levels of mice in each group. The changes of β-catenin and GSK-3β positive neurons in CA1 area of hippocampus in each group were tested by immunohistochemistry. Quantitative real-time polymerase chain reaction (Real-time PCR) was used to measure the mRNA expressions of GSK-3β, β-catenin and CyclinD1 in hippocampus of mice in each group. The Western blot was used to detect the expressions of total GSK-3β (t-GSK-3β), phosphorylation of GSK-3β at Ser9 (p-Ser9-GSK-3β), phosphorylation of GSK-3β at Tyr216 (p-Tyr216-GSK-3β), total β-catenin (t-β-catenin), phosphorylation of β-catenin (p-β-catenin) and CyclinD1 proteins in hippocampus of mice in each group. Result:Compared with the normal control group, mice in AD model group showed an obvious dementia state, which was characterized by significant declines in learning and memory ability, the number of β-catenin immunoreactive neurons in hippocampal CA1 area, the mRNA and protein expressions of t-β-catenin and CyclinD1, the protein expressions of p-Ser9-GSK-3β, and the ratio of p-Ser9-GSK-3β/t-GSK-3β and p-Tyr216-GSK-3β/t-GSK-3β in hippocampal region (P<0.01), and significant increases in the number of GSK-3β immunoreactive neurons in hippocampal CA1 area, the mRNA and protein expressions of t-GSK-3β, the protein expressions of p-Tyr216-GSK-3β and p-β-catenin, the ratio of p-β-catenin/t-β-catenin in hippocampal region (P<0.01 respectively). Compared with the AD model group, the dementia symptoms of mice in HW group were significantly alleviated, and the number of β-catenin immunoreactive neurons in hippocampal CA1 area, the mRNA and protein expressions of t-β-catenin and CyclinD1, the protein level of p-Ser9-GSK-3β, the ratio of p-Ser9-GSK-3β/t-GSK-3β in hippocampal region were all significantly increased (P<0.01 respectively), whereas the number of GSK-3β immunoreactive neurons in hippocampal CA1 area, the mRNA and protein expressions of t-GSK-3β, the proteins expressions of p-Tyr216-GSK-3β and p-β-catenin, the ratio of p-β-catenin/t-β-catenin in hippocampal region were all significantly decreased (P<0.01 respectively), but the ratio of p-Tyr216-GSK-3β/t-GSK-3β has no significant statistical difference. Conclusion:HW shows the role of AD treatment, which can down-regulate the expression of GSK-3β in the hippocampus of AD mice and reduce its protein activity, and up-regulate the expression of β-catenin as well as increase its protein activity, so as to enhance the expression of downstream CyclinD1 and promote the transcription of the target genes. Its mechanism may be related to the activation of Wnt/β-catenin signal pathway.

Objective:To investigate the effect of Huangjingwan (HW) on the activities of glycogen synthase kinase-3β (GSK-3β), protein phosphatase 2A (PP2A) and the mechanism in inhibiting tau protein hyperphosphorylation in the hippocampal neurons of mice with Alzheimer's disease. Method:After subcutaneous injection with 1.0% D-galactose (0.14 g·kg-1·d-1) into the back and neck of mice for 4 weeks, the right ventricle of mice was injected with 2 μL (75 ng) of okadaic acid for one time to make AD model, and the successfully modeled AD mice were selected by Morris water maze. Then, the selected AD mice were randomly divided into AD model group, memantine group (1.3×10-3 g·kg-1·d-1) and HW group (2.5 g·kg-1·d-1). In addition, the sham model control group and the normal control group were set up. At the same time, 2 μL normal saline was injected into the right ventricle of mouse in the sham model control group for modeling control. Two weeks after modeling, the mice in the two experimental drug groups were given the corresponding dose of the experimental drug by gavage for 4 weeks. In addition, after 2 weeks of AD modeling, mice in control group and AD model group were intragastrically administrated with the same amount of normal saline daily for 4 weeks. The mice in normal control group were only given daily feed. At the end of gavage, all the mice were tested by the open field experiment and jumping platform experiment to evaluate the differences in exploratory activity ability, anxiety level and learning and memory ability. The number of neurons in CA1 and CA3 areas of hippocampus in all the mice was detected by Nissl staining. Quantitative real-time polymerase chain reaction (Real-time PCR) was used to detect mRNA expressions of GSK-3β and PP2A in hippocampus of mice in each group. Protein expressions of GSK-3β, PP2A, phosphorylated tau (p-tau) and total tau protein (t-tau) in hippocampus of mice in each group were detected by Western blot. Result:Compared with the normal control group, mice in AD model group showed an obvious dementia state, which was characterized by a lower spontaneous activity, lower exploration behavior ability, higher anxiety level, less movement and easier to stay and hide, longer learning response time, significantly increased number of learning and memory errors, and decreased numbers of hippocampal neuron in CA1 and CA3 areas, and reduced mRNA and protein expressions of PP2A, mRNA and protein expressions of GSK-3β, p-tau protein and the ratio of p-tau/t-tau were all increased significantly (P<0.01), while expression of t-tau protein was decreased, with no significant difference. Compared with the AD model group, mice in the HW group showed a higher spontaneous activity, higher exploration ability, lower anxiety level, higher learning and memory performance, and the numbers of hippocampal neuron in CA1 and CA3 areas increased, while mRNA and protein expressions of PP2A increased, and the mRNA and protein expressions of GSK-3β, the expression of p-tau protein and the ratio of p-tau/t-tau were all decreased significantly (P<0.01), but with no significant difference in the protein expression of t-tau. Conclusion:HW can inhibit tau hyperphosphorylation in hippocampal neurons of AD mice, restore tau protein function, protect hippocampal neurons, and exert an anti-AD effect, which may be related to the regulatory mechanism in the activity balance between GSK-3β and PP2A in hippocampal neurons.

Objective:To investigate the effect of eccentric exercise training on knee function and neuromuscular control in patients with patellofemoral pain syndrome. Methods:From September, 2016 to September, 2019, 39 outpatients with patellofemoral pain syndrome visiting our hospital were randomly divided into control group (n = 19) and experimental group (n = 20). Both groups received routine rehabilitation, while the experimental group received eccentric training of quadriceps femoris in addition, for eight weeks. They were assessed with Visual Analogue Scale (VAS) of pain, Lysholm score, while the acceleration time was measured with Isokinetic Testing and Training System, and stability index with Dynamic Balance Tester. Results:The VAS score, acceleration time of all the muscles, and overall, anterior-posterior and medial-lateral stability indexes decreased (t > 2.521, P < 0.05), and the Lysholm score increased (|t| > 13.628, P < 0.001) in both groups after treatment, while the VAS score, acceleration time of all the muscles, overall and anterior-posterior stability indexes were less (|t| > 2.174, P < 0.05), and the Lysholm score was more (t = 11.947, P < 0.001) in the experimental group than in the control group. Conclusion:Eccentric exercise training of quadriceps femoris is effective on pain, knee function and neuromuscular control for patients with patellofemoral pain syndrome.
摘要
This study aims at the critical role of P-glycoprotein (P-gp) in tumor drug resistance, taking advantage of the adenosine triphosphate (ATP) dependence of P-gp mediated drug transport and efflux across the cell membrane. Mitochondrial targeted calcium arsenite/doxorubicin (DOX) lipid nanoparticles were constructed via hydrothermal method and thin-film dispersion method for reversing tumor drug resistance. The results showed that the lipid nanoparticles were uniform in size and well dispersed with a mean particle size of (261 ± 7) nm, zeta potential of (-9.6 ± 1.3) mV. The DOX loading efficiency and encapsulation efficiency were 22.6% and 84.0%. The in vitro drug release profile was pH-dependent; the drug accumulation at mitochondria was significantly increased, which then caused overload of calcium and inhibition of P-gp and ATP, thereby reversing tumor drug resistance. The simultaneously released arsenite ion and DOX could synergistically kill the tumor cells. In summary, the lipid nanoparticles prepared in this study have uniform particle size, high drug loading efficiency and encapsulation efficiency, excellent colloidal stability, pH responsiveness, and impressive ability to reverse tumor drug resistance, which may hold great potential in further clinical applications.
摘要
Chansu has demonstrated adverse reactions in clinical settings, which is associated with its toxicity and limits its clinical applications. But there are methodological limitations for drug safety evaluation. In the current study, ultra-high performance liquid chromatography, lipidomic profiling, and molecular docking were used to systemically assess Chansu-induced acute inflammatory irritation and further identify the underlying drug targets. Compared with the EtOAc extract, Chansu water fraction containing indolealkylamines caused acute inflammatory irritation in rats, including acute pain (spontaneous raising foot reaction), and inflammation (paw edema). At the molecular level, lipids analysis revealed significantly higher levels of pro-inflammatory mediators of the COX and LOX pathways. However, anti-inflammatory mediators from the CYP 450, ALA, and DHA pathways markedly decreased after exposure to Chansu water fraction. Moreover, four indolealkylamines from Chansu showed a high theoretical affinity to a known irritation target, 5-HT

Objective: To analyze the cardiac magnetic resonance (CMR) imaging feature of clinically diagnosed myocarditis patients with negative endocardial biopsy (EMB) results, and to further demonstrate the diagnostic value of CMR in these patients. Methods: This was a retrospective case series study. Fourteen patients, who were clinically diagnosed as myocarditis according to 2013 European Society of Cardiology (ESC) clinical diagnostic criteria for myocarditis, but with negative EMB results, were enrolled. All patients underwent CMR examinations. The morphological, functional and histological changes of the heart were assessed based on black blood sequence, cine sequence, T2W-STIR sequence and contrast agent late gadolinium enhancement,(LGE). Results: There were 10 males and 4 females in this cohort, the age was (25.6±13.2) years. The interval between symptom onset and CMR was 21 (13, 60) days, and the interval between symptom onset and EMB was 19 (9, 40) days. There were 13 patients with abnormal CMR results including myocardial oedema, fibrosis, decreased ejection fraction, pericardial effusion or increased cardiac chamber dimension. Nine out of 14 patients had CMR morphological and/or functional abnormalities, including 1 case of left atrium enlargement, 1 case of left ventricle enlargement, 3 cases of right ventricle enlargement, 4 cases of increased left ventricular end diastolic volume index. Left ventricular ejection fraction was<50% in three cases, right ventricular ejection fraction was<40% in 5 cases, and pericardial effusion depth>3 mm was detected in 3 cases. Of the 14 patients, 11 had histological changes, of which 6 had T2 ratio≥2. Among the 10 patients (10/14) with positive LGE, the most common patterns were subepicardial LGE of the lateral wall and/or midwall LGE of the septum (n=9); 2 cases showed extensively subendocardial LGE of the left ventricular wall. No LGE involved in the right ventricular wall in the whole cohort. Conclusion: CMR plays a complementary role in the diagnosis of myocarditis in clinically diagnosed myocarditis patients with negative EMB findings.

PKH67-labeled hCC-MSCs-Exo was co-cultured with HCT-116 and HT-29. The effects of hCC-MSCs-Exo on the biological function of colon cancer cell lines were investigated by CCK8 assay, wound healing assay and Transwell invasion assay. RESULTS: The hCC-MSCs showed monolayer adherent growth, fibrocyte-like with positive expression of CD29, CD90, CD105 and negative expression of CD34, CD45, HLA-DR, which have the abilities of osteoblasts and adipocytes. hCC-MSCs-Exo has an average diameter of 135 nanometers and positive expression of Alix, CD63 and CD81. After co-culture with colon cancer cell lines, hCC-MSCs-Exo was uptaken into the colon cancer cells. CCK8, wound healing and Transwell assays showed that the proliferation, migration and invasion ability of co-culture group were significantly enhanced compared with control group (P<0.05). CONCLUSION: hCC-MSCs-Exo can promote the proliferation, migration and invasion of colon cancer cells. It is expected to be a new target for colon cancer treatment.
摘要
Objective To study the intervention effect of systematic nutrition combined with rhythmic exercise on patients with abnormal liver metabolism. Methods According to the theory of system nutrition and health rhythm kinematics, selected 56 subjects with abnormal liver metabolism were selected, and the combined intervention of system nutrition and rhythm movement was conducted regularly every day for 3 consecutive months using the techniques such as liver transient elastography (FibroScan) and bioelectric whole body health scanning system (DDFAO). Results Compared with the pre-intervention period, the liver fat attenuation, liver hardness and liver functional activity of the subjects were significantly improved after intervention. Conclusion The systematic nutrition combined with rhythmic exercise significantly reduced the risk of abnormal liver metabolism in subjects, which may play an important role in preventing liver diseases and promoting the recovery of liver function.
