ABSTRACT

OBJECTIVE@#To identify phytochemical constituents present in the extract of flowers of Xanthoceras sorbifolia and evaluate their anti-oxidant and anti-hyperglycemic capacities.@*METHODS@#The AlCl3 colorimetric method and Prussian Blue assay were used to determine the contents of total flavonoids and total phenolic acids in extraction layers, and the bioactive layers was screened through anti - oxidative activity in vitro. The Waters ACQUITY UPLC system and a Waters ACQUITY UPLC BEH C18 column (2.0 mm × 150 mm, 5 μm) were used to identify the ingredients. And anti-oxidative ingredients were screened by off-line UPLC-QTOF-MS/MS-free radical scavenging. The ameliorative role of it was further evaluated in a high-fat, streptozotocin-induced type 2 diabetic rat model and the study was carried out on NADPH oxidase (PDB ID: 2CDU) by molecular docking.@*RESULTS@#Combined with the results of activity screening in vitro, the anti - oxidative part was identified as the ethyl acetate layer. A total of 24 chemical constituents were identified by liquid chromatography-mass spectrometry in the ethyl acetate layer and 13 main anti-oxidative active constituents were preliminarily screened out through off-line UPLC-QTOF-MS/MS-free radical scavenging. In vivo experiments showed that flowers of X. sorbifolia could significantly reduce the blood glucose level of diabetic mice and alleviate liver cell damage. Based on the results of docking analysis related to the identified phytocompounds and oxidase which involved in type 2 diabetes, quercetin 3-O-rutinoside, kaempferol-3-O-rhamnoside, isorhamnetin-3-O-glucoside, and isoquercitrin showed a better inhibitory profile.@*CONCLUSION@#The ethyl acetate layer was rich in flavonoids and phenolic acids and had significant anti-oxidant activity, which could prevent hyperglycemia. This observed activity profile suggested X. sorbifolia flowers as a promising new source of tea to develop alternative natural anti-diabetic products with a high safety margin.

ABSTRACT

The induction of hepatocyte-like cells (HLCs) in vitro is one of the effective ways to obtain a large number of useful hepatocyte, and these HLCs can be used in disease modeling, drug design, and toxicological evaluation. At present, the induction of HLCs in vitro is mainly achieved by introducing exogenous transcription factors, cytokines or small-molecule compounds. Since small-molecule compounds have the advantages of structural diversity, controllable time and dose, and convenient and safe operation, scientists are devoted to screening out the small-molecule compounds to replace exogenous transcription factors and cytokines, and such compounds have a promising application prospect in the field of regenerative medicine. This article reviews the studies on the in vitro induction of HLCs from pluripotent stem cells and other adult stem cells and summarizes the application of small-molecule compounds in the in vitro induction of HLCs, in order to provide ideas and references for the in vitro induction of HLCs.

ABSTRACT

Objective@#A growing body of research suggests the presence of alexithymia (a form of social cognitive impairment) in patients with schizophrenia (SCZ), which may be related to their psychopathological symptoms. Patients with SCZ exhibit high rates of obesity. Interestingly, studies of the general population have found that alexithymia acts a pivotal role in the development and maintenance of obesity. However, little is known regarding the relationship between obesity, alexithymia, and clinical symptoms in SCZ patients. The study was aim to explore the relationship between obesity, alexithymia, and clinical symptoms in SCZ patients. @*Methods@#Demographic and clinical data were collected from 507 patients with chronic SCZ. Their symptoms were assessed with the Positive and Negative Syndrome Scale (PANSS), and alexithymia was assessed with the Toronto Alexithymia Scale (TAS). @*Results@#Compare with nonobese SCZ patients, obese SCZ patients scored higher on PANSS positive symptoms, TAS total score, difficulty identifying feelings, and difficulty describing feelings (all p<0.05). Correlation analysis revealed a significant association between difficulty identifying feelings and positive symptoms in SCZ patients. Further correlation analysis showed that this association was only present in obese SCZ patients (p<0.05). @*Conclusion@#Obesity may moderate the association between alexithymia and positive symptoms in chronic SCZ patients.

ABSTRACT

Glioma remains the most common malignant tumor in the brain and is also the most difficult to treat. Immunotherapy achieving long-lasting tumor remission in multiple cancer types has received considerable attention due to its potential to improve the treatment outcomes of patients with glioma. However, clinical trials have not yet demonstrated major improvements in prognoses, which might be attributable to the extrinsic components and intrinsic mechanisms involved in the tumor microenvironment and immune system. It is particularly noteworthy that there is emerging evidence that current routine treatment modalities and the physical and psychological characteristics of patients have different impacts on the efficacy of glioma immunotherapy. This article addresses how these factors interact with the host immune system and tumor microenvironment, and highlights their potential roles in glioma immunotherapy, with the ultimate goal of developing better immunotherapybased personalized medicine strategies.

ABSTRACT

Objective To establish the method of predicting the vertical ground reaction force (vGRF) during treadmill running based on principal component analysis and wavelet neural network (PCA-WNN). Methods Nine rearfoot strikers were selected and participated in running experiment on an instrumented treadmill at the speed of 12, 14 and 16 km/h. The kinematics data and vGRF were collected using infrared motion capture system and dynamometer treadmill. A three-layer neural network framework was constructed, in which the activation function of the hidden layers was the Morlet function. Velocities of mass center of the thigh, shank and foot as well as joint angles of the hip, knee and ankle were input into the WNN model. The prediction accuracy of the model was evaluated by the coefficient of multiple correlation (CMC) and error. The consistencies between predicted and measured peak GRF were analyzed by Bland-Altman method. Results The CMC between the predicted and measured GRF at different speeds were all greater than 0.99; the root mean square error (RMSE) between the predicted and measured vGRF was 0.18-0.28 BW; and the normalized root mean square error (NRMSE) was 6.20%-8.42%; the NRMSE between the predicted and measured impact forces and propulsive forces were all smaller than 15%. Bland-Altman results showed that the predicted peak errors of propulsive force at 12 km/h and that of impact force and propulsive force at 14 km/h were within the 95% agreement interval. Conclusions The PCA-WNN model constructed in this study can accurately predict the vGRF during treadmill running. The results provide a new method to obtain kinetic data and perform real-time monitoring on a treadmill, which is of great significance for studying running injuries and rehabilitation treatment.

ABSTRACT

Objective:To investigate the effects and its mechanism of long non-coding RNA (LncRNA) small nucleolar RNA host gene 6 (SNHG6) on proliferation, apoptosis and chemosensitivity of prostate cancer stem cells.Methods:CD44 + CD24 - tumor stem cells and non-CD44 + CD24 - cells were selected from prostate cancer cell PC-3 by flow separation technology, and the expression level of SNHG6 and microRNA (miR) -26a were detected by real-time fluorescence quantitative PCR. Cell proliferation was detected by 5-bromodeoxyuridine (Br-dU) , the apoptosis was detected by flow cytometry, the chemosensitivity of cells to cisplatin was detected by methyl thiazolyl tetrazolium (MTT) , and Western blot was used to detect the protein expressions of proliferating cell nuclear antigen (Ki-67) , B-cell lymphoma-2 (Bcl-2) and Bcl-2 associated X protein (Bax) ; moreover, the target relationships of SNHG6, miR-26a and zeste enhancer of zeste homolog 2 (EZH2) were detected by double luciferase reporter gene assay, and Western blot was used to detect the effect of miR-26a analog on EZH2 protein expression. Results:Compared with non-CD44 + CD24 - cells, the expression level of SNHG6 in CD44 + CD24 - cells was significantly higher ( P<0.05) ; compared with NC-siRNA group [ (1.00±0.06) %, (96.85±6.48) %, (0.72±0.06) %, (0.43±0.03) %, (5.32±0.15) %, (0.35±0.03) %], SNHG6 expression level (0.25±0.03) , cell proliferation activity [ (75.36±5.1) %], Ki67 (0.38±0.03) and Bcl-2 protein (0.21±0.02) expression levels in SNHG6-siRNA group were significantly lower, while miR-26a expression level, apoptosis rate [ (13.83±2.36) %] and Bax protein (0.48±0.03) expression level were significantly higher, and the sensitivity of the cells to cisplatin was significantly higher ( P<0.05) ; in addition, miR-26a was the target gene of SNHG6, EZH2 was the target gene of miR-26a, and miR-26a analog could reduce the expression level of EZH2 protein. Conclusions:SNHG6 is up-regulated in prostate cancer stem cells. Interfering SNHG6 expression can inhibit the proliferation of cancer stem cells, promote apoptosis, and enhance the sensitivity of cancer stem cells to cisplatin. The mechanism may be related to the targeting regulation of miR-26a/EZH2 axis.

ABSTRACT

@#Objective    To summarize the results of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) IgG antibody, total antibody and cellular immune function of COVID-19 convalescent patients one year after discharge, and to analyze the correlation between the SARS-CoV-2 antibody and the indexes of immune function. Methods    A total of 41 confirmed COVID-19 patients discharged from Chengdu Public Health Clinical Medical Center from January to April 2020 and followed up one year after discharge were included in the study as the research group, including 18 males and 23 females with an average age of 47.83±12.95 years. The results of SARS-CoV-2 IgG, total antibody and immune function indexes one year after discharge were collected in order to discuss the correlation of SARS-CoV-2 and cellular immune function. A total of 40 healthy employees of the hospital vaccinated against COVID-19 were randomly selected as the vaccine group, including 10 males and 30 females with an average age of 43.90±6.86 years. The SARS-CoV-2 antibodies between the two groups were compared. Results    CD8+T cell count was higher and CD4+T/CD8+T was lower in male patients than those in female patients (all P<0.05). The IgG and total antibodies in patients with re-detectable positive RNA test were both higher than those in patients without re-detectable positive RNA test, but the differences were not statistically significant (P=0.158, 0.060). The positive rate of SARS-CoV-2 IgG in the research group was 80.5% (33/41). SARS-CoV-2 IgG was positively correlated with total antibody (P<0.001). There was a positive correlation between CD4+T cell count and SARS-CoV-2 IgG (r=0.455, P=0.003). The positive rate of SARS-CoV-2 IgG, SARS-CoV-2 IgG amount and total antibody amount in the research group were significantly higher than those in the vaccine group (all P<0.001). Conclusion    SARS-CoV-2 IgG of most COVID-19 patients one year after discharge is positive, and their SARS-CoV-2 total antibody is significantly higher than people vaccinated against COVID-19, which suggests that patients infected with SARS-CoV-2 can obtain lasting protection, but the protection may be gradually weaken over time. The degree of antibody attenuation in patients with re-detectable positive RNA test may be weaker. In the convalescence stage, the dynamics of SARS-CoV-2 IgG may be closely related to cellular immune function.

ABSTRACT

Objective To investigate the iodine nutritional status and thyroid function of women in early pregnancy after the implementation of a new standard of iodized salt in Chengde. Methods A total of 136 early pregnancy women who had lived in Chengde were randomly selected in this study from January 2018 to March 2020. A questionnaire survey was conducted. The iodized salt, urine and blood samples of the pregnant women were collected to analyze the salt iodine concentration, serum iodine, urinary iodine, serum thyroid stimulating hormone (TSH), free triiodothyronine (FT3), and free thyroxine (FT4). Results In 2018 and 2019, the iodized salt coverage rates were 96.97% and 98.57%, the non-iodized salt rates were 3.03% and 1.43%, the iodized salt qualification rates were 95.45% and 97.14%, and the qualified iodized salt consumption rates were 93.94% and 92.86%, respectively. In addition, the median of iodized salt consumption was 22.20 mg/kg and 25.51 mg/kg, in 2018 and 2019, respectively. There was a statistically significant difference in the median urine iodine from 2018 to 2019 among women in early pregnancy (P0.05). Conclusion After the implementation of a new standard of iodized salt in Chengde, the iodine nutritional status of early pregnant women in 2019 was significantly improved, but there was still a small amount of insufficient iodine intake. The incidence of thyroid diseases in early pregnant women with abnormal iodine intake was higher than that in early pregnant women with appropriate iodine intake.

ABSTRACT

OBJECTIVE@#To assess the clinical value of non-invasive prenatal testing (NIPT) for the screening of trisomy and copy number variations (CNVs) of chromosomes 21, 18 and 13.@*METHODS@#From January 2015 to December 2019, 40 628 pregnant women underwent NIPT testing using high-throughput sequencing and bioinformatics analysis to test the cell-free fetal DNA in maternal plasma. High-risk pregnant women underwent invasive prenatal diagnosis, while low-risk ones were followed up by telephone.@*RESULTS@#The three most common indications included intermediate risk of serological screening, high risk of serological screening and advanced maternal age. Among all pregnant women, 257 cases were detected as trisomy 21, 18 and 13 (170, 49 and 38 cases, respectively). 227 cases chose invasive prenatal diagnosis, with respectively 122, 28 and 10 cases confirmed. The positive predictive value (PPV) was 81.33% (122/150), 65.12% (28/43), 29.41% (10/34), respectively. Two false negative cases of trisomy 18 were found during follow-up. Meanwhile, NIPT has detected 46 cases (15, 16 and 15 cases, respectively) CNVs on chromosomes 21, 18 and 13, among which 37 cases underwent invasive prenatal diagnosis. There were 5, 3 and 5 positive cases, which yielded a PPV of 41.67% (5/12), 25%(3/12) and 33.33%(5/15), respectively. Two other chromosome CNVs were accidentally discovered among the false positive samples.@*CONCLUSION@#The incidence of chromosomal abnormalities in the serological screening high-risk group was 52.02%, which was significantly higher than other groups. NIPT has a high sensitivity and specificity for the screening of trisomies 21, 18 and 13, while its accuracy for detecting CNVs of chromosomes 21, 18 and 13 needs to be improved. As a screening method, NIPT has a great clinical value, though there are still limitations of false positive and false negative results.Comprehensive pre- and post-test genetic counseling should be provided to the patients.

ABSTRACT

Objective To analyze the epidemiological characteristics and risk factors of bronchial asthma (BA) complicated with recurrent respiratory tract infection (RRTI) in children in Hebei District, Tianjin City, and to provide a reference for the prevention and treatment of children with BA complicated with RRTI. Methods The stratified cluster sampling method was adopted to randomly select 428 children with BA hospitalized in Hebei District of Tianjin as the study subjects. The routine deep sputum culture and etiological examination were carried out. The children with RRTI were included in the experimental group (n=84), and the children without RRTI (n=344) were included in the control group. A self-designed questionnaire was used to investigate gender, age, smoking proportion of family members, use of antibiotics 3 times or more a year, and family history of allergy. The risk factors of BA combined with RRTI were analyzed by logistic regression. Results RRTI occurred in 84 of 428 children with BA, and the incidence rate was 19.63% (84/428). The proportion of BA complicated with RRTI in children aged 6 months to 2 years was higher than that in other age groups (χ2=6.213, P0.05). The proportion of family smoking, the use of antibiotics 3 times or more a year, and the proportion of family allergy history in the experimental group were significantly higher than those in the control group (P<0.05). Logistic regression analysis showed that family smoking, antibiotic use 3 times or more a year and family history of allergy were independent risk factors for BA complicated with RRTI (P<0.05). Conclusion The incidence of BA complicated with RRTI in children in Hebei District, Tianjin City is high, and the age of high incidence is 6 months to 2 years old. The proportion of family smoking, the use of antibiotics three times or more a year, and the proportion of family allergy history are the high-risk factors for the occurrence of BA complicated with RRTI in children in Hebei District, Tianjin City.

The dominant virus strains with different types appeared dynamically in different years. EV-A71 was the predominant serotype in severe and aggregated cases. Laboratory confirmed cases were mainly children under 5 years old (96.25%).@*Conclusions@#From 2010 to 2018, the pathogen of HFMD in Dezhou city showed a dynamic change, with obvious seasonal distribution of cases and high incidence of specific population. Etiological surveillance should be strengthened to focus on prevention and control of high-risk population in high-risk season.

ABSTRACT

Objective To investigate the efficacy and adverse reaction of three-dimensional conforml radiotherapy (3DCRT) combined with thalidomide and GEMOX regimen (gemcitabine + oxaliplatin) in patients with advanced intrahepatic cholangiocarcinoma.Methods A total of 100 patients with advanced intrahepatic cholangiocarcinoma in 901 Hospital of Joint Logistics Support Force of Chinese People's Liberation Army from March 2015 to June 2018 were divided into chemotherapy group (n =50) and combination group (n =50) by random number table method.The chemotherapy group was treated with thalidomide and GEMOX regimen,and the combined group was treated with 3DCRT on the basis of the chemotherapy regimen.The levels of serum tumor markers,clinical efficacy and adverse reactions of patients in the two groups were compared before and after treatment.Results The levels of serum carcinoembryonic antigen (CEA),carbohydrate antigen 125 (CA125) and carhohydrate antigen 19-9 (CA19-9) in the combined group were (8.76 ± 2.69) μg/L,(76.17 ± 10.12) × 103 U/L and (169.85 ± 78.97) × 103 U/L respectively,which were significantly lower than those of (12.46 ± 3.47) μg/L,(104.56 ± 14.38) × 103 U/L,(312.45 ± 71.36) × 103 U/L in the chemotherapy group,with statistically significant differences (t =5.959,P < 0.001;t =11.416,P < 0.001;t =9.474,P < 0.001).The clinical benefit rate and the total effective rate of the combined group were respectively 64.0% (32/50) and 88.0% (44/50),which were higher than those of 42.0% (21/50) and 72.0% (36/50) in the chemotherapy group,with statistically significant differences (x2 =4.857,P =0.028;x2 =4.000,P =0.046).The incidences of leukopenia,nausea and vomiting,constipation and alopecia of patients in the combined group were 20.0% (10/50),24.0% (12/50),30.0% (15/50) and 12.0% (6/50) respectively,which were 14.0% (7/50),16.0% (8/50),24.0% (12/50) and 8.0% (4/50) respectively in the chemotherapy group,with no statistically significant differences (x2 =0.638,P =0.424;x2 =1.000,P =0.317;x2 =0.457,P =0.499;x2 =0.444,P =0.505).Conclusion 3DCRT combined with thalidomide and GEMOX regimen can significantly reduce the levels of serum tumor markers in patients with advanced intrahepatic cholangiocarcinoma,enhance the short-term efficacy without significantly increasing and aggravating adverse reactions.
