RESUMO
OBJECTIVE:: This study evaluated the possible effect of the combined intervention of physical exercise and cognitive training on cognitive function in stroke survivals with vascular cognitive impairment. DESIGN:: A single-blind (investigator-blinded but not subject-blinded) randomized controlled trial. SETTING:: Medical Rehabilitation Center of Shanghai General Hospital, China. SUBJECTS:: A total of 225 patients (mean age 64.59 years, SD = 4.27) who exhibited vascular cognitive impairment were included in this study. INTERVENTIONS:: Patients were randomly allocated into one of the four groups: (1) physical exercise ( n = 56; 50-minute session), (2) cognitive training ( n = 57; 60-minute session), (3) combined intervention of physical exercise and cognitive training ( n = 55; 50-minute session + 60-minute session), or (4) control groups ( n = 57; 45-minute session). All participants received training for 36 sessions, three days per week, for 12 weeks. PRIMARY MEASURES:: Measures were recorded at baseline, after the intervention and at a six-month follow-up. Primary measurements included the Trail Making Part B, Stroop, forward digit span, and mental rotation tests. RESULTS:: A total of 179 participants (79.56% response rate) completed the study. Cognitive performances on all four tasks in the combined training group improved significantly after the intervention ( P < 0.01). Changes in cognitive performance were greater in the combined intervention group than those in the physical exercise group (e.g. forward digit span, 13.61% vs. 2.18%, P = 0.003), the cognitive training group (e.g. mental rotation, 17.36% vs. 0.87%, P = 0.002), and the control group (e.g. Stroop, -4.11% vs. -0.72%, P = 0.026). CONCLUSION:: The combined intervention produced greater benefits on cognitive function compared to either training alone in stroke survivors with vascular cognitive impairment.

OBJECTIVE: To conduct a Meta-analysis of studies on the effect of Aidi injection combined with chemotherapy versus chemotherapy alone in the treatment of gastric cancer (GC). METHODS: Nine electronic databases and six gray literature databases were comprehensively searched until April 20, 2013. Two reviewers independently selected and assessed included trials according to the inclusion and exclusion criteria. The risk of bias tool from the Cochrane Handbook version 5.1.0 was used to assess trial quality. All calculations were performed using Review Manager 5.0. RESULTS: Thirty-two studies including 1927 participants met the inclusion criteria, most of which were low quality. Compared with chemotherapy alone, Aidi injection plus the same chemotherapy significantly improved the effective rate [OR = 1.52, 95% CI (1.24, 1.86), P < 0.0001], clinical beneficial rate [OR = 1.77, 95% CI (1.33, 2.36), P < 0.0001], and quality of life [OR = 3.02, 95% CI (2.39, 3.82), P < 0.000 01]. There was a significant improvement in nausea and vomiting incidence [OR = 0.34, 95% CI (0.24, 0.47), P < 0.000 01], diarrhea [OR = 0.47, 95% CI (0.33, 0.69), P < 0.000 01], leukopenia (III-IV) [OR = 0.34, 95% CI (0.23, 0.51), P = 0.05], hemoglobin decrease (III-IV) [OR = 0.42, 95% CI (0.18-1.00), P = 0.05], thrombocytopenia (III-IV) [OR = 0.46, 95% CI (0.22, 0.96), P = 0.04], and damage to liver function [OR = 0.36, 95% CI (0.24, 0.54), P < 0.00001]. CONCLUSION: Aidi injection combined with chemotherapy significantly improved the clinical effect of chemotherapy, reducing the incidence of adverse events. Use of the CONSORT statement for randomized controlled trials is recommended for stricter reporting.

OBJECTIVE: To explore the sensitivity and specificity of Golgi protein 73 (GP73) monoclonal antibody in the diagnosis of hepatocellular carcinoma (HCC). METHODS: Self-prepared GP73 monoclonal antibody was used as the primary antibody for detecting the serum GP73 levels in healthy controls(n=31)and HCC patients (n=59). The baseline level of the healthy controls was determined by semiquantitative analysis. The results were compared with those from GP73 polyclonal antibody and alpha-fetoprotein (AFP). RESULTS: The GP73 level of healthy controls was 1.2 (0.9-1.7) relative unit (RU), which was significantly lower than that of HCC patients [5.7 (2.5-7.8) RU] (P<0.001) with monoclonal antibody. Using polyclonal antibody, the GP73 level of HCC patients was also significantly higher than healthy controls [7.8 (3.0-12.4) RU vs. 1.1 (1.0-2.0) RU, P<0.001]. The sensitivity and specificity of GP73 monoclonal antibody in diagnosis of HCC were 84.7% and 93.5%; on the contrary, those of GP73 polyclonal antibody were 78.0% and 93.5%, respectively. The sensitivity and specificity of AFP (67.8% and 74.2%, respectively) in the HCC patients were markedly lower than those of GP73. Logistic regression analysis showed that the odds ratio (OR) of GP73 monoclonal antibody was 7.18 and that of GP73 polyclonal antibody was 1.51. CONCLUSIONS: Our self-prepared monoclonal antibody can effectively detect GP73 serum level in HCC patients, and has higher sensitivity and specificity than AFP. It may be superior to the currently used GP73 polyclonal antibody. The results lay the foundation for the further development of ELISA methods by using this monoclonal antibody.

Space cooling and heating consume a large proportion of global energy, so passive thermal management materials (i.e., without energy input), especially dual-mode materials including cooling and heating bifunctions, are becoming more and more attractive in many areas. Herein, a function-switchable Janus membrane between cooling and heating consisting of a multilayer structure of polyvinylidene fluoride nanofiber/zinc oxide nanosheet/carbon nanotube/Ag nanowire/polydimethylsiloxane was fabricated for comprehensive thermal management applications. In the cooling mode, the high thermal radiation emissivity (89.2%) and sunlight reflectivity (90.6%) of the Janus membrane resulted in huge temperature drops of 8.2-12.6, 9.0-14.0, and 10.9 °C for a substrate, a closed space, and a semiclosed space, respectively. When switching to the heating mode, temperature rises of 3.8-4.6, 4.0-4.8, and 12.5 °C for the substrate, closed space, and semiclosed space, respectively, were achieved owing to the high thermal radiation reflectivity (89.5%) and sunlight absorptivity (74.1%) of the membrane. Besides, the Janus membrane has outstanding comprehensive properties of the membrane, including infrared camouflaging/disguising, electromagnetic shielding (53.1 dB), solvent tolerance, waterproof properties, and high flexibility, which endow the membrane with promising application prospects.

RESUMO
OBJECTIVES@#To study the factors influencing the short-term (28 days) efficacy of initial adrenocorticotropic hormone (ACTH) therapy for infantile epileptic spasms syndrome (IESS), as well as the factors influencing recurrence and prognosis.@*METHODS@#The clinical data were collected from the children with IESS who received ACTH therapy for the first time in the Department of Pediatric Neurology, Xiangya Hospital of Central South University, from April 2008 to January 2018 and were followed up for ≥2 years. The multivariate logistic regression analysis was used to evaluate the factors influencing the short-term efficacy of ACTH therapy, recurrence, and long-term prognosis.@*RESULTS@#ACTH therapy achieved a control rate of seizures of 55.5% (111/200) on day 28 of treatment. Of the 111 children, 75 (67.6%) had no recurrence of seizures within 12 months of follow-up. The possibility of seizure control on day 28 of ACTH therapy in the children without focal seizures was 2.463 times that in those with focal seizures (P<0.05). The possibility of seizure control on day 28 of ACTH therapy in the children without hypsarrhythmia on electroencephalography on day 14 of ACTH therapy was 2.415 times that in those with hypsarrhythmia (P<0.05). The possibility of recurrence within 12 months after treatment was increased by 11.8% for every 1-month increase in the course of the disease (P<0.05). The possibility of moderate or severe developmental retardation or death in the children without seizure control after 28 days of ACTH therapy was 8.314 times that in those with seizure control (P<0.05). The possibility of moderate or severe developmental retardation or death in the children with structural etiology was 14.448 times that in those with unknown etiology (P<0.05).@*CONCLUSIONS@#Presence or absence of focal seizures and whether hypsarrhythmia disappears after 14 days of treatment can be used as predictors for the short-term efficacy of ACTH therapy, while the course of disease before treatment can be used as the predictor for recurrence after seizure control by ACTH therapy. The prognosis of IESS children is associated with etiology, and early control of seizures after ACTH therapy can improve long-term prognosis.

Enzyme separation, purification, immobilization, and catalytic performance improvement have been the research hotspots and frontiers as well as the challenges in the field of biocatalysis. Thus, the development of novel methods for enzyme purification, immobilization, and improvement of their catalytic performance and storage are of great significance. Herein, ferritin was fused with the lichenase gene to achieve the purpose. The results showed that the fused gene was highly expressed in the cells of host strains, and that the resulted fusion proteins could self-aggregate into carrier-free active immobilized enzymes in vivo. Through low-speed centrifugation, the purity of the enzymes was up to > 90%, and the activity recovery was 61.1%. The activity of the enzymes after storage for 608 h was higher than the initial activity. After being used for 10 cycles, it still maintained 50.0% of the original activity. The insoluble active lichenase aggregates could spontaneously dissolve back into the buffer and formed the soluble polymeric lichenases with the diameter of about 12 nm. The specific activity of them was 12.09 times that of the free lichenase, while the catalytic efficiency was 7.11 times and the half-life at 50 ℃ was improved 11.09 folds. The results prove that the ferritin can be a versatile tag to trigger target enzyme self-aggregation and oligomerization in vivo, which can simplify the preparation of the target enzymes, improve their catalysis performance, and facilitate their storage.

Objective: To explore the epidemiological characteristics and treatment outcomes of patients with hydrofluoric acid burns in hands. Methods: A retrospective observational study was conducted. The medical records of 229 patients with hydrofluoric acid burns in hands who were admitted to Zhejiang Quhua Hospital from January 2008 to December 2020 and met the inclusion criteria were collected. The following statistical data of patients were collected, including gender, age, type of affiliated enterprise, hydrofluoric acid mass fraction, injury site, total burn area, prehospital time, length of hospital stay, length of wound healing, whether hypocalcemia and hypomagnesemia occurred or not on admission, whether surgery intervention was performed or not, and whether scar sequelae occurred or not. Single factor and multivariate logistic regression analysis were used to screen out the risk factors impacting surgery intervention and scar sequelae of all the patients and patients whose hydrofluoric acid mass fraction was known. Single factor and multivariate linear regression analysis were used to screen out the risk factors impacting the length of wound healing of all the patients and patients whose hydrofluoric acid mass fraction was known. Results: The 229 patients included 206 males and 23 females, with the majority aged 30 to 50 years (139 patients). The type of affiliated enterprise of majority patients was non-fluorine chemical enterprise. The hydrofluoric acid mass fraction was known in only 91 patients, mainly medium. The majority injury site was in the middle and end of finger. The total burn area was below or equal to 1% total body surface area. The prehospital time was 19 (9, 29) h. The length of hospital stay was 2 (1, 7) d. The length of wound healing was 12 (8, 18) d. The proportions of hypocalcemia and hypomagnesemia were 0.9% (2/229) and 1.3% (3/229) on admission, respectively. Thirty-six patients had surgeries and 83 patients had scar sequelae. In 229 patients, single factor logistic regression analysis showed that both type of affiliated enterprise and prehospital time were the factors impacting surgery intervention (with odds ratio values of 7.86 and 51.35, respectively, 95% confidence intervals of 1.83-33.76 and 11.89-221.78, respectively, P<0.01) and scar sequelae of patients (with odds ratio values of 3.62 and 27.40, respectively, 95% confidence intervals of 1.76-7.43 and 13.25-56.68, respectively, P<0.01); multivariate logistic regression analysis showed that prehospital time was the independent risks factor impacting surgery intervention and scar sequelae of patients (with odds ratio values of 43.00 and 24.55, respectively, 95% confidence intervals of 9.89-187.03 and 11.78-51.16, respectively, P<0.01); single factor linear regression analysis showed that both type of affiliated enterprise and prehospital time were the factors impacting the length of wound healing of patients (with β values of 6.16 and 12.83, respectively, 95% confidence intervals of 3.38-8.93 and 10.72-14.93, respectively, P<0.01); multivariate linear regression analysis showed that both type of affiliated enterprise and prehospital time were the independent risk factors impacting the length of wound healing of patients (with β values of 2.81 and 12.16, respectively, 95% confidence intervals of 0.50-5.13 and 10.00-14.31, respectively, P<0.05 or P<0.01). In 91 patients whose hydrofluoric acid mass fraction was known, single factor logistic regression analysis showed that type of affiliated enterprise, hydrofluoric acid mass fraction (low and high), and prehospital time were all the factors impacting surgery intervention of patients (with odds ratio values of 9.10, 11.25, 10.69, and 0.04, respectively, 95% confidence intervals of 1.15-72.25, 1.39-90.93, 1.32-86.59, and 0.01-0.19, respectively, P<0.05 or P<0.01), type of affiliated enterprise, hydrofluoric acid mass fraction, and prehospital time were all the factors impacting scar sequelae of patients (with odds ratio values of 0.32, 0.21, and 36.80, respectively, 95% confidence intervals of 0.11-0.92, 0.06-0.73, and 11.03-122.79, respectively, P<0.05 or P<0.01); multivariate logistic regression analysis showed that both hydrofluoric acid mass fraction and prehospital time were the independent risk factors impacting surgery intervention of patients (with odds ratio values of 11.51 and 0.04, respectively, 95% confidence intervals of 1.22-108.26 and 0.01-0.25, respectively, P<0.05 or P<0.01), prehospital time was the independent risk factor impacting scar sequelae of patients (odds ratio=37.71, with 95% confidence interval of 9.97-142.69, P<0.01); single factor linear regression analysis showed that type of affiliated enterprise, hydrofluoric acid mass fraction (low and high), and prehospital time were all the factors impacting the length of wound healing of patients (with β values of 7.12, -5.63, -9.74, and 13.50, respectively, 95% confidence intervals of 2.43-11.81, -10.59--0.68, -14.78--4.70, and 10.14-16.86, respectively, P<0.05 or P<0.01); multivariate linear regression analysis showed that both hydrofluoric acid mass fraction and prehospital time were the independent risk factors impacting the length of wound healing of patients (with β values of -5.84 and 0.09, respectively, 95% confidence intervals of -10.59--1.08 and 0.05-0.12, respectively, P<0.05 or P<0.01). Conclusions: The majority of patients with hydrofluoric acid burns in hands are young and middle-aged males. Type of affiliated enterprise, hydrofluoric acid mass fraction and prehospital time are the risk factors that affect the treatment outcomes of patients with hydrofluoric acid burns in hands.

Background Ultrasound-guided continuous thoracic paravertebral block can provide pain-relieving and opioid-sparing effects in patients receiving open hepatectomy. We hypothesize that these effects may improve the quality of recovery (QoR) after open hepatectomy. Methods Seventy-six patients undergoing open hepatectomy were randomized to receive a continuous thoracic paravertebral block with ropivacaine (CTPVB group) or normal saline (control group). All patients received patient-controlled intravenous analgesia with morphine postoperatively for 48 hours. The primary outcome was the global Chinese 15-item Quality of Recovery score on postoperative day 7, which was statistically analyzed using Student's t-test. Results Thirty-six patients in the CTPVB group and 37 in the control group completed the study. Compared to the control group, the CTPVB group had significantly increased global Chinese 15-item Quality of Recovery scores (133.14 ± 12.97 vs. 122.62 ± 14.89, P = 0.002) on postoperative day 7. Postoperative pain scores and cumulative morphine consumption were significantly lower for up to 8 and 48 hours (P < 0.05; P = 0.002), respectively, in the CTPVB group. Conclusion Perioperative CTPVB markably promotes patient's QoR after open hepatectomy with a profound analgesic effect in the early postoperative period.

ILF3 antisense RNA 1 (ILF3-AS1), the antisense RNA of interleukin enhancer binding factor 3 (ILF3), is a lncRNA located on chromosome 19p13. 2. ILF3-AS1 played a key role in the occurrence and development of a variety of tumors, but its role in cervical cancer had not been explored yet. Therefore, we first used TCGA and GTEx database to conduct bioinformatics analysis. The results suggested that ILF3-AS1 was down-regulated in cervical cancer tissues (P < 0. 001) and was associated with a good prognosis (P = 0. 045). The qRT-PCR experiment showed that expression of ILF3-AS1 in cervical cancer tissues and SiHa, HeLa, CaSki cervical cancer cell lines was lower than that in control groups. Subsequently, overexpressing of ILF3-AS1 can significantly inhibit the cancer cell viability and stimulate apoptosis (P<0. 001). Analysis using the Star Base v3. 0 database suggested that ILF3-AS1 can target miR-130a-3p; while miR-130a-3p may target PTEN. The qRT-PCR test showed that the expression of miR-130a-3p in cervical cancer was significantly higher than that in normal cervical tissues (P < 0. 01). The results of the luciferase reporter assay showed that ILF3-AS1 can specifically bind to miR-130a-3p (P<0. 01). After overexpression of ILF3-AS1 in HeLa cells, the expression of miR-130a-3p was significantly down-regulated (P < 0. 01). Co-transfection with pcDNA3. 1-ILF3-AS1 and miR-130a-3p mimics, the inhibitory effect of LF3-AS1 on cell proliferation can partially be reversed (P<0. 001). After HeLa cells overexpressed ILF3-AS1, the expression of phosphatase and tensin homolog deleted on chromosome ten (PTEN) mRNA (P < 0. 001) and proteins (P < 0. 001) significantly increased; when miR-130a-3p mimics was simultaneously used in HeLa cell, the increased expression of PTEN mRNA (P <0. 001) and proteins (P < 0. 001) was notably inhibited. In summary, ILF3-AS1 inhibited the proliferation of cervical cancer cells by sponging miR-130a-3p to regulate the expression of PTEN.
RESUMO
OBJECTIVE@#To study the clinical features and recurrence factors of myelin oligodendrocyte glycoprotein (MOG) antibody disease in children and the effect of recurrence prevention regimens.@*METHODS@#A retrospective analysis was performed on the medical data of 41 children with MOG antibody disease who were hospitalized in the Department of Pediatric Neurology, Xiangya Hospital of Central South University, from December 2014 to September 2020. According to the presence or absence of recurrence, they were divided into a monophasic course group (@*RESULTS@#For these 41 children, acute disseminated encephalomyelitis was the most common initial manifestation and was observed in 23 children (56%). Of the 41 children, 22 (54%) experienced recurrence, with 57 recurrence events in total, among which optic neuritis was the most common event (17/57, 30%). The proportion of children in the recurrence group who were treated with corticosteroids for less than 3 months in the acute phase was higher than that in the monophasic course group (64% @*CONCLUSIONS@#More than half of the children with MOG antibody disease may experience recurrence. Most children with recurrence are treated with corticosteroids for less than 3 months in the acute phase. Rituximab and azathioprine may reduce the risk of recurrence.

Objective:To systematically evaluate the clinical efficacy of laparoscopic common bile duct exploration (LCBDE) combined with endoscopic nasobiliary drainage (ENBD) versus T-tube drainage in the treatment of choledocholithiasis.Methods:Databases including PubMed(Medline), Embase, the Cochrane Library, Web of Science, Wanfang, CNKI and CBM were searched for literatures from January 1960 to May 2019 with the key words including "胆总管结石病,胆总管结石; T管引流, T管;鼻胆管引流,经内镜鼻胆管引流术, ENBD管, ENBD引流; cholelithiasis, common bile duct stone, jaundice, obstructive, Jaundice, gallstone; T-tube drainage, T-tube, t-tube, biliary tract drainge, drainge tube; endoscopic nasobiliary drainage, nasobiliary drainage, nasobiliary tube, endoscopic drainage tubes, endoscopic drainage tube, endoscopic retrograde biliary drainage" . The randomized controlled trials (RCTs) and high quality non-randomized controlled trials (NRCTs) on comparing ENBD and T-tube drainage during laparoscopic choledocholithotomy were included.Patients who received LCBDE combined with preoperative or intraoperative ENBD were allocated into ENBD group, and patients who received LCBDE combined with postoperative T-tube drainage were allocated into T-tube drainage group. Reported outcomes: operation time, volume of intraoperative blood loss, duration of postoperative hospital stay, time to drainage tube removal, time to postoperative gastrointestinal function recovery, treatment expenses, rate of surgical failure, incidence of postoperative biliary fistula, incidence of postoperative incisional infection, incidence of postoperative residual stones, incidence of postoperative pancreatitis, incidence of postoperative hyperamylasemia, incidence of postoperative bile peritonitis. Count data were represented as odds ratio ( OR) and 95% confidence interval (95% CI). Measurement data were represented as mean difference ( MD) and 95% CI. The I2 and Q tests were used to analyze literature heterogeneity. I2≤50% or P>0.10 indicated no significant heterogeneity, so fixed effects model was used for Meta analysis. I2>50% and P≤0.10 indicated a significant heterogeneity, so random effects model was used for Meta analysis. When analyzing the measurement data, subgroup analysis of individual indicators was performed if there were more than 4 RCTs included, and NRCTs were analyzed for supplement if there were no more than 4 RCTs included. When analyzing the count data, RCTs and NRCTs were combined for analysis. Funnel plots were used to test potential publication bias if there were more than or equal to 10 studies included, while no test was needed if there were less than 10 studies included. Results:(1) Document retrival: 26 literatures meeting the standards were included, including 9 RCTs and 17 NRCTs (4 semi-randomized studies and 13 case-control studies). There were 2 098 patients, including 1 114 patients in the ENBD group and 984 patients in the T-tube drainage group. (2) Results of Meta analysis. ① Duration of postoperative hospital stay: there was a significant difference in the duration of postoperative hospital stay between the ENBD group and T-tube drainage group ( MD=-6.53, 95% CI: -8.64 to -4.43, P<0.05). Further analysis of 9 RCTs showed significant differences in the duration of postoperative hospital stay between patients without acute complications of choledocholithiasis in the ENBD group and those in the T-tube drainage group, between patients with acute complications of choledocholithiasis in the ENBD group and T-tube drainage group, respectively ( MD=-5.88, -8.77, 95% CI: -8.32 to -3.45, -12.39 to -5.15, P<0.05). ② Time to drainage tube removal: for the RCTs, there was a significant difference in the time to drainage tube removal between the ENBD group and T-tube drainage group ( MD=-46.01, 95% CI: -83.64 to -8.37, P<0.05). For the NRCTs, there was a significant difference in the time to drainage tube removal between the ENBD group and T-tube drainage group ( MD=-24.05, 95% CI: -32.93 to -15.18, P<0.05). ③ Time to postoperative gastrointestinal function recovery: for the RCTs, there was a significant difference in the time to postoperative gastrointestinal function recovery between the ENBD group and T-tube drainage group ( MD=17.80, 95% CI: -31.11 to -4.48, P<0.05). For the NRCTs, there was a significant difference in the time to drainage tube removal between the ENBD group and T-tube drainage group ( MD=-5.64, 95% CI: -10.16 to -1.12, P<0.05). ④ Incidence of postoperative biliary fistula: there was a significant difference in the incidence of postoperative biliary fistula between the ENBD group and T-tube drainage group ( OR=0.50, 95% CI: 0.28-0.89, P<0.05). ⑤ Incidence of postoperative incisional infection: there was a significant difference in the incidence of postoperative incisional infection between the ENBD group and T-tube drainage group ( OR=0.35, 95% CI: 0.17-0.73, P<0.05). (3) Analysis of publication bias. The incidence of postoperative biliary fistula in the two groups was analyzed by funnel plot based on the 15 studies. The bilateral symmetry was presented in the funnel plot for incidence of postoperative biliary fistula, suggesting that publication bias had little influence on results of Meta analysis. Conclusion:For patients with choledocholithiasis that endoscopic lithotomy is not feasible, LCBDE combined with ENBD can significantly shorten duration of postoperative hospital stay, time to drainage tube removal, postoperative gastrointestinal function recovery time, reduce the incidence of postoperative biliary fistula and incisional infection compared with LCBDE combined with T-tube drainage.
RESUMO
Objective:To investigate the clinical value of serum miR-208a in early differential diagnosis of acute coronary syndrome(ACS).Methods:One hundred ACS patients admitted to our department from January 2016 to January 2018 were randomly divided into the non-ST elevation myocardial infarction(NSTEMI)group(n=50)and the unstable angina(UA)group(n=50). Fifty healthy people during the same period were included as the control group(control). Serum levels of miR-208a, cardiac troponin-T(cTnT)and creatine kinase MB isoenzyme(CK-MB)were detected immediately, 4 h, 12 h and 24 h after admission and compared among the three groups of NSTEMI, UA and control.Receiver operating characteristic(ROC)curve was used to analyze the early diagnostic value of above serum indexes in NSTEMI and UA group, and the correlations of miR-208a level with cTnT and CK-MB were analyzed.Results:Serum miR-208a and cTnT levels had significant differences( P<0.05), while serum CK-MB level had no significant difference( P>0.05)among the NSTEMI and UA groups immediately after admission and the control group in the fasting state.There were significant differences in serum miR-208a, cTnT and CK-MB levels between NSTEMI group and UA group at different time points( P<0.05). After further multiple comparisons, the results showed that serum miR-208a and cTnT levels had statistical differences( P<0.05)and serum CK-MB level had no difference( P>0.05)between the NSTEMI group and the UA group immediately after admission.The above three biochemical indexes showed statistically significant differences between the NSTEMI group and the UA group at 4 h, 12 h and 24 h after admission( P<0.05). ROC curve analysis showed that miR-208a had a high diagnostic value in ACS(AUC>0.9, P=0.004), and the best diagnostic cut-off point was 9.278.The cTnT had a medium diagnostic value in ACS(0.7<AUC<0.9, P=0.013), and the diagnostic cut-off point was 5.147 μg/L.CK-MB had a low diagnostic value in ACS(0.5<AUC<0.7, P=0.031), and the diagnostic cut-off point was 82.716 u/l.Serum miR-208a level was positively correlated with cTnT level in ACS patients( P<0.05), and there was no correlation between serum miR-208a level and CK-MB level( P>0.05). Conclusions:Serum miR-208a has a higher value in early diagnosis of ACS than cTnT and CK-MB, and it has a better differentiation ability of NSTEMI than UA.
RESUMO
Objective:To identify objective markers between the Parkinson variant of multiple system atrophy (MSA-P) and Parkinson′s disease (PD).Methods:Retrospective analysis was performed on 10 patients with MSA-P, 15 patients with PD, and 15 healthy control group during the period from August 2016 to February 2019 in Baoshan Branch of Shanghai First People′s Hospital.We combined the novel tract based spatial statistics (TBSS) and region of interest (ROI) analyses for the first time to investigate three groups with diffusion tensor imaging. By TBSS, we performed pairwise comparisons of mean diffusivity and fractional anisotropy (FA) maps. The clusters with significant differences between MSA-P and PD were used as ROIs for further analyses.Results:FA values in the left anterior thalamic radiation(ATR) (ROI values were 0.371(0.287-0.535), 0.472(0.390-0.594), 0.473(0.388-0.555); P values were 0.008, 0.008) and left superior longitudinal fasciculus (SLF)(ROI values were 0.397(0.291-0.469), 0.456(0.338-0.560), 0.473(0.427-0.530); P values were 0.013,<0.001) were significantly decreased in MSA-P compared with PD or controls, and significantly correlated with clinical data(( r =-0.807, P =0.005),( r =-0.455, P =0.022)). Conclusion:Our findings indicate the abnormalities of left ATR and left SLF as specific biomarkers for differential diagnosis.

RESUMO
OBJECTIVE: To study the apoptosis and chemosensitive effect of As(2)O(3) on human lung adenocarcinoma cell line A549. METHODS: MTT colorimetric assay, immunohistochemical method, flow cytometry and RT-PCR were applied to observe the different effects induced by As(2)O(3) with different concentrations on A549 cells. RESULTS: 1, 2 micro mol/L As(2)O(3) increased Fas expression and inhibited the expression of bcl-2, MRP and LRP; G(1) arrest was observed and the cells were more sensitive to cisplatin. A549 cells in the presence of 5 micro mol/L As(2)O(3) showed growth inhibition and up-regulation of bcl-2, MRP and LRP expressions; but their chemosensitivity to cisplatin did not change. CONCLUSION: As(2)O(3) in low concentrations can increase the chemosensitivity of A549 cells by regulating the expression of apoptosis genes, anti-apoptosis genes and drug-resistant genes and affecting the cell cycle progress.

Objective To investigate the relationship between serum markers β amyloid (Aβ), tau and thyroid hormone levels and post-stroke cognitive impairment (PSCI) in the acute phase of cerebral infarction. Methods A total of 214 patients with acute cerebral infarction were enrolled. The baseline data and serological indicators were collected and the cognitive function of patients was evaluated. All patients were divided into cognitive impairment group and normal group based on follow-up results. The differences of Aβ1-42, tau protein and thyroxine levels between the two groups and their relationship with disease progression were analyzed. The Cox regression analysis and ROC curve were used to compare the above parameters to predict the development of PSCI. Results The total protein level of Tau (210.6 ±98.9 pg/mL) was higher and Aβ1-42 (426.1 ±123.5 pg/mL) and triiodothyronine (T3) (1.43 ±0.57 nmol/L), free thyroxine (FT4) (13.15±2.23 pmol/L) was significantly lower in the cognitive impairment group than in the normal group (P<0.05). Tau protein (r=-0.457), Aβ1-42 (r=0.348), T3 (r=0.211), and FT4 (r=0.306) were all associated with disease progression (P<0.05). Cox regression analysis showed that Aβ1-42 and T3 were important influencing factors in the occurrence of PSCI. The area under the curve of Aβ1-42 combined with T3 was 0.841. The specificity and the sensitivity were 74.8% and 85.3%, respectively, with a diagnostic cutoff value of 0.572. Conclusion Aβ1-42 and T3 levels in the acute phase of cerebral infarction may predict the progression of PSCI.
RESUMO
Objective To investigate the correlation between myeloperoxidase(MPO)levels and adverse cardiac events in patients undergoing coronary stent implantation.Methods A total of 76 patients undergoing coronary stent implantation from January 2015 to June 2016 in the cardiac surgery department of our hospital were enrolled in this study.Serum levels of MPO,high sensitivity C-reactive protein(hs-CRP),and interleukin 6 (IL-6)were detected by enzyme-linked immunosorbent assays(ELISA).After a one-year follow-up,the receiver operating characteristic(ROC)curve was used to determine the predictive value of the difference in MPO before and after the operation(△MPO)on the long-term prognosis of patients after coronary stent implantation.The correlations of △MPO with the traditional risk factors for coronary heart disease and adverse cardiac events were analyzed using multi factor Logistic regression analysis.Results Serum levels of MPO,hs-CRP and IL 6 increased in patients after coronary stent implantation,compared with those before treatment (P < 0.05).The results of ROC curve analysis showed that the area under the curve(AUC)value of serum △MPO was 0.786,the 95 % confidence interval was 0.471~ 1.000 and the predictive value of serum △MPO for adverse cardiac events was significant(P <0.05).There was a significant correlation between △MPO and age,and the incidence of adverse cardiac events increased with increased △MPO levels.Logistic regression analysis showed that serum △MPO levels could preliminarily diagnose the cardiovascular risk after coronary stent implantation and independently predict the occurrence of adverse cardiac events.Conclusions MPO levels in peripheral blood are notably elevated in patients after coronary stent implantation when compared with pre-treatment levels.Serum △MPO levels can preliminarily diagnose adverse cardiac events after coronary stent implantation and can be used as a marker to predict adverse cardiac events.
RESUMO
Objective To compare metabolic syndrome(MS)with Framingham risk score as predictors of cardiovascular disease( CVD) among Kazakhs. Methods The participants were the residents who had been followed up for more than 5 years in representative areas of Kazakhs in Xinjiang. We assigned MS a continuous risk score for predicting the development of CVD based on the weights of MS components. MS and Framingham risk score were compared in terms of their ability in predicting years in representative areas of Kazakhs in Xinjiang. We assigned MS a continuous risk score for predicting the development of CVD based on the weights of MS components. MS and Framingham risk score were compared in terms of their ability in predicting development of CVD using Cox regression and receiver operating characteristic curve. Results The incidence of CVD was 13.87%. The incidence of CVD was higher in the MS group than it in the non-MS group(21.59% vs 11.10%, P<0.001). The area under the receiver operating characteristic(ROC)curve of MS risk score was significantly larger than that of MS classification(0.727 vs 0.585, P<0.001);the area under the curve of MS risk score was close to that of Framingham risk score ( 0. 732 vs 0.727, P=0.673). The association between CVD and each quintile of MS risk score was more significant than that between Framingham risk score and CVD under the same exposed condition(4.61、9.33、14.15、22.29对3.69、6.36、8.47、16.99) . Conclusion MS risk score that included age may be a better predictor of CVD among Kazakhs.
