ABSTRACT

Objective:To explore the intervention effect of cognitive-walking dual-task training on executive and walking function in patients with cerebral apoplexy.Methods:A total of 70 stroke patients who were hospitalized in the Department of Rehabilitation Medicine of Baoding Taihe Rehabilitation Hospital from June 2020 to October 2020 were selected as the study subjects.All 70 hemiplegic patients with stroke were randomly divided into control group ( n=35) and test group ( n=35) by random number table method, and a prospective study was conducted.The control group was given routine walking training, and the test group was given cognitive-walking dual-task training at the same time and frequency as the control group.E-Prime software was used to evaluate the executive function of patients before and 4 weeks after intervention, including three sub-tests of Flanker, 1-back and More-odd shifting, and the reaction time of each test was recorded.The score changes of Mini-Mental Status Examination (MMSE) and Modified Rankin Scale (MRS) were recorded.The single-task walking time, dual-task walking time and dual-task walking time cost during 10 m Walk Test were calculated.Finally, 33 cases in the experimental group and 31 cases in the control group completed the study.Finally, 33 cases in the experimental group and 31 cases in the control group completed the study. Results:After 4 weeks of intervention, the MMSE scores of the experimental group and the control group were improved compared with those before intervention (the experimental group (26.39±1.90) and (24.42±2.69), t=10.824, P<0.001; the control group (25.45±1.77) and (24.61±2.16), t=7.325, P<0.001), and the experimental group was significantly better than the control group ( t=2.049, P=0.045)). The duration of three tests of executive function in the experimental group and the control group was significantly shorter than that before the intervention (Flanker task: the experimental group (752.38±178.28) ms and (939.42±260.11) ms, t=10.467, P<0.001; the control group (863.40±227.86) ms and (951.67±265.93) ms, t=8.140, P<0.001.1-back task: the experimental group (983.31±314.16) ms and (1 242.10±444.77) ms, t=10.386, P<0.001; the control group (1 186.89±293.80) ms and (1 238.27±305.95) ms, t=9.569, P<0.001.More odd shifting task: the experimental group (1 121.29±260.17) ms and (1 362.32±352.80) ms, t=13.084, P<0.001; the control group (1 255.81±269.41) ms and (1 351.37±287.46) ms, t=8.550, P<0.001), and the experimental group was significantly better than the control group (Flanker task: t=2.198, P=0.032; 1-back task: t=2.691, P=0.009; more odd shifting task: t=2.044, P=0.045). The results of 10 m walking test in the experimental group and the control group were improved compared with those before the intervention (single task walking time: the experimental group (20.71±9.61) s and (26.10±13.88) s, t=6.312, P<0.001; the control group (22.42±9.60) s and (25.62±10.97) s, t=13.009, P<0.001). The duration of dual task walking: the experimental group (22.73±10.28) s and (31.64±16.07) s, t=7.931, P<0.001; the control group (28.30±11.72) s and (31.89±13.65) s, t=9.348, P<0.001.The cost of dual task walking: the experimental group (10.32±6.87)% and (23.26±11.40)%, t=10.602, P<0.001; the control group (27.39±7.38)% and (24.94±7.48)%, t=2.719, P=0.011). The 10 m walking test time of the experimental group was shorter than that of the control group ( t=2.027, P=0.047), and the walking time cost of the experimental group was lower than that of the control group ( t=9.583, P<0.001). Conclusion:Cognitive walking dual task training can improve the walking function of patients, which is more conducive to the recovery of executive function than conventional walking training.

ABSTRACT

Nonalcoholic fatty liver disease (NAFLD) is regarded as the most common liver disease with no approved therapeutic drug currently. Silymarin, an extract from the seeds of Silybum marianum, has been used for centuries for the treatment of various liver diseases. Although the hepatoprotective effect of silybin against NAFLD is widely accepted, the underlying mechanism and therapeutic target remain unclear. In this study, NAFLD mice caused by methionine-choline deficient (MCD) diet were orally administrated with silybin to explore the possible mechanism and target. To clarify the contribution of peroxisome proliferator-activated receptor α (PPARα), PPARα antagonist GW6471 was co-administrated with silybin to NAFLD mice. Since silybin was proven as a PPARα partial agonist, the combined effect of silybin with PPARα agonist, fenofibrate, was then evaluated in NAFLD mice. Serum and liver samples were collected to analyze the pharmacological efficacy and expression of PPARα and its targets. As expected, silybin significantly protected mice from MCD-induced NAFLD. Furthermore, silybin reduced lipid accumulation via activating PPARα, inducing the expression of liver cytosolic fatty acid-binding protein, carnitine palmitoyltransferase (Cpt)-1a, Cpt-2, medium chain acyl-CoA dehydrogenase and stearoyl-CoA desaturase-1, and suppressing fatty acid synthase and acetyl-CoA carboxylase α. GW6471 abolished the effect of silybin on PPARα signal and hepatoprotective effect against NAFLD. Moreover, as a partial agonist for PPARα, silybin impaired the powerful lipid-lowering effect of fenofibrate when used together. Taken together, silybin protected mice against NAFLD via activating PPARα to diminish lipid accumulation and it is not suggested to simultaneously take silybin and classical PPARα agonists for NAFLD therapy.

ABSTRACT

Objective:To investigate the effects of estrogen receptor beta agonist diarylpropionitrile (DPN) on mesenteric artery (MA) responsiveness and on Rho-kinase signaling pathway in cirrhotic portal hypertension rats, and to elucidate the mechanism of ER beta agonist in visceral hyperdynamic circulation in cirrhotic portal hypertension rats.Methods:Female rats were treated with bilateral ovariectomy, and CCl 4 was injected to establish cirrhotic portal hypertension model. After intervention, hemodynamic parameters and vascular reactivity of MA in each group were measured, and the levelof ER beta, Rho-kinase signaling pathway-related proteins and receptor desensitization-related proteins in MA in each group were detected. Results:DPN could significantly improve the hemodynamic parameters of ovariectomized cirrhosis rats and the response of MA to norepinephrine. DPN could increase the level of inhibited ROCK protein and decrease the expression of beta-arrestin-2 and the phosphorylation of ERK1/2.Conclusions:DPN could improve the responsiveness of MA to vasoconstrictor substances, and significantly improve the hyperdynamic circulation in ovariectomized cirrhosis rats. This effect may be related to DPN improving the desensitization of MA to vasoconstrictor receptors and the Rho-kinase pathway activation.

ABSTRACT

Experimental Traditional Chinese Medicine is an emerging discipline that plays an important role in cultivating innovative talents of traditional Chinese medicine (TCM). In recent years, with the rapid development of TCM and the new requirements of positioning, and also combined with the college students' cognitive characteristics, we have revised and republished the "Experimental TCM" (Third Edition) textbook, which focuses on introducing knowledge by adopting relevant scientific research cases. This test book was used in the teaching of undergraduates of batch 2013 in the eight-year program in Shanghai University of Traditional Chinese Medicine. After-class questionnaires showed that this teaching mode, guided by scientific research case, is not only helpful for students to develop their quality and ability of adopting modern experimental methods initially in the study and development of TCM, but also able to spread the great achievements of TCM researches. The teaching mode is also conducive to enhancing students' sense of responsibility for the modernization of TCM. Therefore, it is suggested that the course of Experimental TCM should be promoted in the colleges and universities of TCM.

ABSTRACT

Objective:To evaluate the teaching effect of moral education materials implied in scientific research cases in the teaching of "Experimental Traditional Chinese Medicine (TCM)".Methods:The moral education materials implied in scientific research cases of "Experimental TCM" were extracted and skillfully integrated into the teaching of professional knowledge. A questionnaire survey was conducted with questions as "whether it is good to demonstrate the potential humanistic spirit by case teaching, whether this helps improve your interest in science and whether this teaching form affects your study, life and work attitude in the future" "Ten specific items from scientists' moving deeds that touch students and their recognitions" to assess the teaching effect.Results:95.8 percent of students affirmed this teaching form and thought it helped improve their interest in scientific exploration. 87.5 percent of students considered the humanistic spirit would affect their study, life and work in the future. 77.1-89.6 percent of students held a positive attitude to the ten items derived from the scientists' moving stories. Among these items, the percentages of the two items, "the spirit of being able to endure loneliness, work hard to make contributions selflessly without seeking for rewards or reputations" and "having respect forpeople and their scientific research achievements with courage to challenge the authorities of scientific research" are the lowest and highest, respectively.Conclusion:It is good to apply the moral education materials implied in the scientific research cases in the teaching of "Experimental TCM", which basically achieves the teaching goal, but there is still room for improvement.

ABSTRACT

BACKGROUND@#Despite the recent large number of studies comparing endoscopic and laparoscopic resection for small gastrointestinal stromal tumors (GISTs) (diameter ≤ 5 cm), the results remain conflicting. The objective of this work was to perform a cumulative meta-analysis to assess the advantages and disadvantages of endoscopic resection vs. laparoscopic resection.@*METHODS@#The meta-analysis followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement. We searched medical databases up to January 2020. Meta-analytical random or fixed effects models were used in pooled analyses. Meta-regression, cumulative meta-analyses, and subgroup analyses were performed to improve the accuracy of the conclusion. Sensitivity analyses were applied to assess the robustness of the results.@*RESULTS@#A total of 12 cohort studies with 1383 participants comparing endoscopic resection and laparoscopic resection were identified, while three cohort studies with 167 participants comparing endoscopic resection and laparoscopic and endoscopic cooperative surgery were found. We found that endoscopic resection had shorter operation times (weighted mean difference [WMD] = -27.1 min, 95% confidence interval [CI]: -40.8 min to -13.4 min) and lengths of hospital stay (WMD = -1.43 d, 95% CI: -2.31 d to -0.56 d) than did laparoscopic resection. The results were stable and reliable. There were no significant differences in terms of blood loss, hospitalization costs, incidence of complications or recurrence rates. For tumor sizes 2 - 5 cm, endoscopic resection increased the risk of positive margins (relative risk [RR] = 5.78, 95% CI: 1.31 - 25.46). Although operation times for endoscopic resection were shorter than those of laparoscopic and endoscopic cooperative surgery (WMD = -41.03 min, 95% CI: -59.53 min to -22.54 min), there was a higher incidence of complications (RR = 4.03, 95% CI: 1.57 - 10.34).@*CONCLUSIONS@#In general, endoscopic resection is an alternative method for gastric GISTs ≤ 5 cm. Laparoscopic and endoscopic cooperative surgery may work well in combination. Further randomized controlled trials are recommended to validate or update these results.

ABSTRACT

Objective To investigate the feasibility and technique of using the anterolateral thigh perforator flap pedicled with the lateral branch of the lateral circumflex femoral artery (LBLCFA) to repair soft tissue defect of extremities.Methods Eighty-six cases of anterolateral thigh perforator flap transplantation were performed from May,2014 to May,2018.A total of 37 cases of soft tissue defect of extremities were treated by anterolateral thigh perforator flap used the LBLCFA as vascular pedicle,of which there were 19 cases of upper limbs and 18 of lower limbs.There were 27 cases of defects caused by trauma,and 10 by soft tissue tumor resection.The flaps were designed centering around the point proximal to the midpoint of the iliac-patellar line.The dimensions of soft tissue defect were from 9.0 cm×6.0 cm to 26.0 cm×10.0 cm,and the flap were from 10.0 cm×7.0 cm to 27.0 cm×11.0 cm.The length of vascular pedicle ranged of 7.0-13.0 cm,with an average of 11.5 cm.The donor sites were directly sutured.All of the patients were followed-up regularly in the outpatient department.Results All the flaps survived and the donor sites were primarily healed.Of these 37 cases,2 trauma patients and 2 patients treated with local radiotherapy had poor wound healing,but still healed after multiple dressing changes.All the patients were followed-up for 3-26 months,with an average of 13 months.The texture,color and elasticity of the flap were similar to the surrounding tissue of the recipient sites,while only a linear scar remained at the donor sites.Ten tumor patients were treated with routine radiotherapy and chemotherapy after the repairation;there was no tumor recurrence during the follow-up period.Conclusion The LBLCFA gives off a relatively large and thick perforator proximal 5.0-7.0 cm of the iliacpatellar line,which locates in the upper lateral side,travels parallel to the vastus lateralis,and give off the skin and muscular perforators.The lateral branch can be used as pedicle to make into perforator flap or chimeric flap,which provides a novel selection of vascular pedicel for anterolateral thigh perforator flap.When the descending branch does not provide a thick and large perforator,the LBLCFA has important practical value and is worth utilizing in the clinic.

ABSTRACT

To analyze the frequency and spectrum of thalassemia mutations in amniotic fluid samples collected from Han and Li people in Hainan province of China. Methods: We carried out a retrospective analysis on prenatal diagnosis of amniotic fluid samples collected from pregnant women who may have next generation with high risks of medium or severe thalassemia between 2005 and 2016. Diverse fetal thalassemia genotypes and mutated alleles in Han and Li people were analyzed and cmpared. Results: We examined 536 amniotic fluid samples from Han people and 588 from Li people, among which 406 Han and 500 Li samples were found to carry at least one thalassemia gene mutation, with a detection rate of 75.75% and 85.03%, respectively. Among all - and β-thalassemia mutant alleles detected, the most frequently found mutations in Han and Li samples were SEA-type of -thalassemia and 41/42 (-CTTT) of β-thalassemia, respectively. A total of 75 severe thalassemia cases were identified in Han samples and 53 in Li samples. In most of these severe cases, parents chose to terminate pregnancy after being informed of thalassemia-related risks. Conclusions: The thalassemia mutations shows ethnic and area specificity, and that prenatal diagnosis for high-risk thalassemia carrier pregnant women is an efficient approach to prevent and control the occurrence of severe thalassemia in the high-prevalence areas.

ABSTRACT

Objective To investigate the expressions of transforming growth factor β1 (TGF-β1) and brain natrium peptide (BNP) in patients with diastolic heart failure (DHF),and to explore the correlation between plasma levels of TGF-β1,BNP and TGF-β1/BNP with parameter of diastolic function,diastolic dysfunction and New York Heart Association (NYHA) classification of cardiac function.Methods Hospitalized patients with DHF from October 2016 to November 2017 in Beijing Chaoyang Hospital were selected as subjects.At the same time,the age-and gender-matched non-heart failure hospitalized patients were selected as the control.The diastolic function index (E/e') was measured using cardiac ultrasound spectral Doppler and tissue Doppler methods.The diastolic dysfunction classification was evaluated according to the American Society of Echocardiography guidelines.Cardiac function was evaluated with NYHA classification.The levels of plasma TGF-β1 and BNP were measured with method of enzyme linked immunosorbent assay (ELISA).The correlation between the indicators was analyzed and the receiver operating characteristic (ROC) curve was drawn.Results A total of 186 patients were enrolled,including 114 patients as DHF group [54 males and 60 females,mean age (70.75 ± 11.45) years old] and 72 cases as control group [41 males and 31 females,mean age (68.74 ± 10.86) years old].The levels of TGF-β1 [(77.68 ± 42.31) ng/L] and BNP [(1 153.84 ± 564.96) ng/L] in patients with DHF were significantly higher than those of the control group [(18.76 ± 13.70),(264.07 ± 179.43) ng/L,t =15.62,13.77,P < 0.01].Pearson correlation analysis showed that level of plasma TGF-β1 had a significant liner correlation with index E/e' (r =0.582,P < 0.01),level of plasma BNP had a low-degree liner correlation with index E/e' (r =0.261,P < 0.01),and TGF-β1/BNP had no correlation with index E/e' (r =0.081,P > 0.05).Spearman correlation analysis showed that the levels of TGF-β1 and BNP were significantly correlated with diastolic dysfunction grading (r =0.473,0.417,P < 0.01),while TGF-β1/BNP had no correlation with diastolic dysfunction grading (r =0.062,P > 0.05).Plasma TGF-β1 and BNP had low-degree correlation with NYHA classification of heart failure (r =0.309,0.326,P < 0.01),TGF-β1/BNP had no correlation with NYHA classification of heart failure (r =0.011,P > 0.05).Logistic analysis showed that both plasma TGF-β1 and BNP were independent predictors of DHF (OR =1.264,2.283,P < 0.05 or < 0.01).The area under ROC curve (AUC) of BNP for prediction of DHF was 0.937 ± 0.064,and TGF-β1 was 0.597 ± 0.042.AUC areas of BNP and TGF-β1 were significantly different (P < 0.01).Conclusions The expressions of plasma TGF-β1 and BNP in patients with DHF are higher than those without DHF.The levels of plasma TGF-β1 and BNP are significantly correlated with index E/e',diastolic dysfunction grading and NYHA classification.Both elevated BNP and TGF-β1 levels are independent predictors of DHF.Both plasma BNP and TGF-β1 have auxiliary diagnostic value on DHF and the diagnostic value of plasma BNP is greater than plasma TGF-β1.

ABSTRACT

Seven main components in eleutheroside were used as research objects, and the mechanism of action of total eleutheroside for treatment of diabetes mellitus type 2 was investigated by network pharmacology. The SwissTargetPrediction, GeneCard, and String platforms were used to predict the 35 potential targets of these 7 components that are related to diabetes mellitus type 2. Then we used cytoscape 3.6.1 to build a "component-target" network map and used the Networkanalyzer tool for topology analysis. Gene ontology (GO) enrichment analysis and KEGG pathway enrichment analysis were performed on the DAVID6.8 platform, and the "component-target-path" network map was constructed based on the enrichment results. Those components mainly used in diabetes mellitus type 2 were screened as core components, and the core components were docked with key disease target proteins to verify the potential mechanism of the total eleutheroside. After screening, 8 important pathways associated with diabetes mellitus type 2 were identified. This study showed that eleutheroside A, eleutheroside D, eleutheroside E and sesamin played key roles in insulin resistance, apoptosis and inflammation pathways. The total eleutheroside may ameliorate type 2 diabetes mainly through regulating signal transducer and activator of transcription factors (STATs), non-receptor protein tyrosine phosphatase (PTPN) 1, PTPN2, c-Jun N-terminal kinase (JNK), and p38 mitogen activate protein kinase. These components worked together through multiple signaling pathway. Based on our data, eleutheroside is proposed as a novel therapeutic strategy for treatment of type 2 diabetes.

ABSTRACT

UDP-glycosyltransferase PgUGT74AE2 from Panax ginseng can transfer a glucose moiety to the free C-3 hydroxyl of protopanaxadiol (PPD) to produce ginsenoside Rh2. However, no report demonstrates that PgUGT74AE2 can transfer a glucose moiety to the free C-3 hydroxyl of protopanaxatriol (PPT) to produce a PPT-type ginsenoside. In this study, the expression plasmid pET-32a-PgUGT74AE2 was constructed for expression of the recombinant protein and transferred into Escherichia coli Transetta (DE3) to generate the recombinant strain Transetta-PgUGT74AE2. The recombinant enzyme PgUGT74AE2 was expressed by induction of isopropyl-β-D-thiogalactoside (IPTG). An in vitro enzymatic reaction system was established with the recombinant enzyme PgUGT74AE2 and the substrate PPT. PgUGT74AE2 catalyzed the glycosylation of the free C-3 hydroxyl of PPT to produce 3-O-β-D-glucopyranosyl-dammar-24-ene-3β,6α,12β,20S-tetraol, a new PPT-type ginsenoside. This study provides an efficient approach for the biosynthesis of a new PPT-type ginsenoside through in vitro enzymatic reaction, which may pave a way to produce promising lead in drug discovery.

ABSTRACT

Objective To understand the clinical distribution characteristics and antimicrobial resistance of pathogens causing healthcare-associated infection(HAI) in a comprehensive hospital.Methods Clinical data of patients with HAI in this hospital between May 2012 and May 2015 were collected,the distribution and antimicrobial resistance of pathogens isolated from patients were analyzed.Results A total of 6 563 cases of HAI occurred among 183 850 patients,incidence of HAI was 3.57%,445 patients were isolated at least two kinds of pathogens,375 (84.27%) patients were isolated two kinds of pathogens,132 of whom were infected with both gram negative bacilli.4 478 specimens were sent for pathogenic detection,2 503 (55.90%) of which were isolated pathogens;a total of 2 755 pathogens were isolated,including 1 713(62.18%) strains of gram-negative bacilli,732(26.57%) gram positive cocci,304(11.03%) yeast-like fungi,and 6(0.22%) anaerobic bacteria.524(19.02%)strains were mainly from patients in department of neurology.The main specimen was sputum (n =1 340,48.64%).The isolation rates of carbapenem-resistant Escherichia coli (CREC),Klebsiella pneumoniae (CRKP),Acinetobacter baumnannii (CRAB),and Pseudomonas aeruginosa (CRPA) were 0.39% (2/510),1.66% (3/181),59.14% (207/ 350),and 5.29 % (11/208) respectively;isolation rate of methicillin-resistant Staphylococcus aureus (MRSA) was 21.55%(25/116).Conclusion Multidrug-resistant organisms causing HAl are various,it is necessary to understand distribution characteristics and prevalence of pathogens,monitor multidrug-resistant organisms,and implement contact isolation measures,so as to prevent the outbreak of HAI.

ABSTRACT

Thiochromanones and 1,3,4-thiadazoles as heterocyclic compounds have broad biological activities. In order to find novel compounds with antifungal bioactivity, substituted thiophenol and maleic anhydride were used to synthesize the intermediate 4-oxothiochromane-2-carboxylic acid. It was reacted with 2-amino-1,3,4-thiadiazol to get fourteen target compounds containing 1,3,4-thiadazole moiety. The structures of the obtained compounds were confirmed by 1H NMR, 13C NMR and HR-MS. All compounds were investigated for antifungal activity via microdilution broth method. The results showed that the target compounds 3a and 3c to Epidermophyton floccosum and Mucor racemosus exhibited better antifungal activity than the positive control fluconazole, in which the minimum inhibition concentration can reach 8 μg·mL-1 and 16 μg·mL-1. Compound 3e showed significant inhibitory activity to Helminthosporium maydis, Sclerotinia sclerotiorum and Botrytis cinerea compared with that of the positive control carbendazim. Compound 3b exhibited inhibitory activity to Helminthosporium maydis better than the positive control carbendazim.
