RESUMO

Objective@#To investigate the regulatory relationship of Protein Phosphatase 2 Regulatory Subunit B"Alpha ( PPP2R3A) and hexokinase 1 ( HK1) in glycolysis of hepatocellular carcinoma (HCC).@*Methods@#In HepG2 and Huh7 cells, PPP2R3A expression was silenced by small interfering RNA (siRNA) and overexpression by plasmid transfection. The PPP2R3A-related genes were searched by RNA sequencing. Glycolysis levels were measured by glucose uptake and lactate production. QRT-PCR, ELISA, western blot and immunofluorescence assay were performed to detect the changes of PPP2R3A and HK1. Cell proliferation, migration and invasion assay were used to study the roles of HK1 regulation by PPP2R3A.@*Results@#RNA sequencing data revealed that PPP2R3A siRNA significantly downregulated the expression of HK1. PPP2R3A gene overexpression promotes, while gene silencing suppresses, the level of HK1 and glycolysis in HCC cells. In HCC tissue samples, PPP2R3A and HK1 were colocalized in the cytoplasm, and their expression showed a positive correlation. HK1 inhibition abrogated the promotion of glycolysis, proliferation, migration and invasion by PPP2R3A overexpression in liver cancer cells.@*Conclusion@#Our findings showed the correlation of PPP2R3A and HK1 in the glycolysis of HCC, which reveals a new mechanism for the oncogenic roles of PPP2R3A in cancer.

RESUMO

Objective:To analyze rehabilitation of functioning of mobility for critically ill patients based on the framework of the World Health Organization Family International Classifications (WHO-FICs). Methods:A scoping review of rehabilitation of functioning of mobility for critically ill patients had been conducted. Literatures on early mobilization or rehabilitation in the field of critical illness from databases of Web of Science, PubMed, CNKI, and Wanfang up to February 28, 2021 were retrieved. The diseases, functioning, rehabilitation intervention, functioning evaluation and environment of patients in critical ward had been reviewed. Results:Based on WHO-FICs framework, this paper reviewed literatures in five dimensions: the type of diseases, functioning, rehabilitation intervention, functioning evaluation and environment factors. The diseases included respiratory system diseases (MD10-MD6Y), neurological system diseases (MB40-MB9Y), cardiovascular system diseases (MC80-MC9Y), post-surgical (MD80-ME4Y, ME60-ME6Y, ME80-MF1Y), and others (NA00-NF2Z, MA00-MA3Y, 1G40-1G41). The functioning included movement-related structures (s720-s760), neuromusculoskeletal and movement-related functions (b710-b740), mobility (d4), self-care (d5), and remunerative employment (d850). The rehabilitation interventions were divided into three categories based on the International Classification of Health Interventions (ICHI) β-3: therapeutic, preventive, and health promotion interventions. The evaluation of functioning mainly involved joint mobility, muscle strength, muscle tone, de Morton Mobility Index, Functional Status Score for Intensive Care Unit (FSS-ICU), 6-Minute Walking Test (6WMT), intensive care unit (ICU) length of stay and so on. The intensive care environment was also discussed using ICF environment factors. Conclusion:This paper proposed a framework of rehabilitation of mobility for critically ill patients based on the WHO-FICs. It focused on respiratory system disease, neurological system diseases, cardiovascular system diseases, post-surgical with mobility dysfunction. To implement interventions in therapeutic, preventive, and health promotion to optimize patients' function, and to prevent complications and secondary dysfunction, and improve their well-being.

RESUMO

Three compounds, including scolosprine C(1), uracil(2) and hypoxanthine(3), were isolated and purified from the ethyl acetate fraction of centipede by silica gel normal-phase column chromatography, reversed-phase medium pressure preparation chromatography, and high-pressure semi-preparative HPLC. The structure was elucidated through a combination of spectroscopic analyses [such as nuclear magnetic resonance(NMR) and mass spectrometry(MS)] and literature review. Among them, compound 1 was a new quinoline alkaloid. In previous reports, we have described the isolation and structure elucidation of one new and two known quinoline alkaloids. In this paper, we would report the isolation and structure elucidation of scolosprine C in detail.

RESUMO

Objective To investigate the prevalence of Demodex infection among students in Kunming Medical University, and identify the factors affecting Demodex infections, so as to provide the evidence for the development of the strategy for the prevention of Demodex infections. Methods A total of 1 463 students from Grade 2014 who studied Medical Parasitology in Kunming Medical University were included in the survey. Demodex was examined in students’facial skin using the cellophane tape method, and the species was identified using microscopy. The students’gender, ethnicity, place of origin and skin type were captured using a questionnaire survey. Results The overall prevalence of Demodex infections was 19.07% (279/1 463) on the facial skin among the university students, and a higher prevalence was seen in girls (21.16%, 183/865) than in boys (16.05%, 96/598) (χ2 =5.965,P <0.05).TheprevalenceofDemodex infectionswas18.33%(66/360)amongminorethnicstudents,andnoethnicity-specific prevalence was seen (P > 0.05). Demodex folliculorum was the predominant species, with a prevalence of 50.54% (141/279), and mild infections were predominant among all infections (96.77%, 270/279), without severe infections seen. Multivariate nonconditional logistic regression analysis revealed that gender and roommates with Demodex infections were risk factors of Demodex infections, and the infection was not associated with ethnicity, place of origin or skin type. There were only 2.53% (37/1 463) of the subjects understanding the knowledge pertaining to the prevention and control of Demodex infection. Conclusions A relatively low prevalence of Demodex infection is detected in the facial skin of students from Kunming Medical University, and Demodex infection is associated with gender and roommates with Demodex infections. Health education pertaining to the prevention of Demodex infections is suggested to be intensified among university students.

RESUMO

Background:@#Visual-spatial neglect (VSN) is a neuropsychological syndrome, and right-hemisphere stroke is the most common cause. The pathogenetic mechanism of VSN remains unclear. This study aimed to investigate the behavioral and event-related potential (ERP) changes in patients with or without VSN after right-hemisphere stroke.@*Methods:@#Eleven patients with VSN with right-hemisphere stroke (VSN group) and 11 patients with non-VSN with righthemisphere stroke (non-VSN group) were recruited along with one control group of 11 age- and gender-matched healthy participants. The visual-spatial function was evaluated using behavioral tests, and ERP examinations were performed.@*Results:@#The response times in the VSN and non-VSN groups were both prolonged compared with those of normal controls (P < 0.001). In response to either valid or invalid cues in the left side, the accuracy in the VSN group was lower than that in the non-VSN group (P < 0.001), and the accuracy in the non-VSN group was lower than that in controls (P < 0.05). The P1 latency in the VSN group was significantly longer than that in the control group (F[2, 30] = 5.494, P = 0.009), and the N1 amplitude in the VSN group was significantly lower than that in the control group (F[2, 30] = 4.343, P = 0.022). When responding to right targets, the lefthemisphere P300 amplitude in the VSN group was significantly lower than that in the control group (F[2, 30] = 4.255, P = 0.025). With either left or right stimuli, the bilateral-hemisphere P300 latencies in the VSN and non-VSN groups were both significantly prolonged (all P < 0.05), while the P300 latency did not differ significantly between the VSN and non-VSN groups (all P > 0.05).@*Conclusions:@#Visual-spatial attention function is impaired after right-hemisphere stroke, and clinicians should be aware of the subclinical VSN. Our findings provide neuroelectrophysiological evidence for the lateralization of VSN.

RESUMO

OBJECTIVE@#To assess the feasibility and efficacy of simvastatin-collagen composite sponge as a novel, direct pulp capping material.@*METHODS@#A total of 120 Sprague-Dawley rats were randomly divided into three groups: the simvastatin-collagen composite sponge group (SIM group), the collagen sponge group (CS group), and the Ca(OH)2 group (CH group). An endodontic entry cavity was prepared on the occlusion of the first molar on the left maxillary of each rat. The contralateral teeth were utilized as the normal control group. The rats were experimented after 1, 3, 7, 14, and 28 days. X-ray observations were conducted and the specimens underwent hematoxylin-eosin (HE) and Masson's Thichrome staining. Dentin bridge formations and pulpal biology reactions were evaluated histopathologically.@*RESULTS@#X-ray results: high-density images could be observed on the pulp exposure sites in the CH group on the 28th day. In the SIM group, high-density images could be observed after 14 and 28 days, whereas in the CS group, high-density images were not observable in the exposed area. HE and Masson's Thichrome staining results: different degrees of inflammation under the cavity were detected in the three groups at different time points. The inflammatory reaction of the CS group was the most serious. The degree of the inflammatory reaction varied significantly between the SIM and the CS groups on the 14th and 28th days (P<0.01). The inflammatory reaction in the SIM group was lighter than in the CH group. There was a statistical difference between the SIM and the CH groups on the 14th day (P<0.05). During the observation period, the SIM group induced the best and fastest formation of reparative dentin. As for dentin bridge formation, a significantly higher complete bridge rate was observed in the SIM group than in the CH and in the CS groups on the 14th day (P<0.05) and for the SIM and the CH groups compared with the CS group on the 28th day (P<0.05).@*CONCLUSIONS@#The simvastatin-collagen composite sponge exhibited satisfactory biocompatibility with the pulp tissue and promoted the formation of reparative dentin. The application of simvastatin-collagen composite sponge as a pulp-capping material has satisfactory potential.

RESUMO

<p><b>OBJECTIVE</b>To explore the long-term prognosis and health-related quality of life of patients surviving hepatitis B virus-related acute-on-chronic liver failure (HBV-ACLF).</p><p><b>METHODS</b>The clinical data were collected from patients with HBV-ACLF, who were hospitalized in our department between November, 2011 and October, 2016 and survived for more than 90 days. The patients were followed for occurrence of newly diagnosed cirrhosis, decompensation events, hepatocellular carcinoma and death. The quality of life of the patients was evaluated using SF-36 score, and the patients with chronic hepatitis B (CHB) and cirrhosis treated during the same period served as controls.</p><p><b>RESULTS</b>A total of 223 ACLF survivors were included in this study. According to the presence of cirrhosis on admission, the enrolled patients were divided into chronic hepatitis B-related ACLF (CHB-ACLF) group (n=130) and liver cirrhosis ACLF (CIR-ACLF) group (n=93). The 12-, 24- and 50-month survival rates in CHB-ACLF group were 97%, 95.7% and 93.9%, respectively, significantly higher than the rates in CIR-ACLF group (91%, 86% and 74%, respectively; P=0.007). In patients with CHB-ACLF, the 12-, 24- and 36-month progression rates of cirrhosis were 37.9%, 58.4% and 68.7% respectively. Multivariate Cox regression identified the peak value of serum creatinine (HR=1.015, P=0.026) and INR (HR=2.032, P=0.006) within 28 days as independent risk factors and serum sodium at baseline (HR=0.84, P=0.035) as an independent protective factor of occurrence of cirrhosis. The score of mental health on SF-36 in ACLF group was significantly lower than the national norms, and the scores for general health and body pain of ACLF patients were significantly higher than those in patients with CHB or cirrhosis.</p><p><b>CONCLUSION</b>The long-term prognosis of ACLF survivors with and without cirrhosis can be different. Acute attacks are associated with an increased rate of cirrhosis progression in CHB patients who recovered from ACLF, possibly in relation with the severity of extra-hepatic organ injuries. The physical and social functions of long-term survivors of ACLF do not significantly decline, but their psychological status can be affected.</p>

RESUMO

<p><b>Objective</b>To investigate the correlation between the premature ejaculation diagnostic tool (PEDT) and International Index of Erectile Function-15 (IIEF-15) in different types of premature ejaculation (PE).</p><p><b>METHODS</b>We performed a cross-section survey among 352 PE patients received in the andrology clinic from December 2014 to December 2015 and 104 healthy men from the health examination center using basic demographic information (as on age, height, weight, education status, occupation, income, etc.), PEDT results, and IIEF-15 scores of the subjects.</p><p><b>RESULTS</b>The PE patients had remarkably higher PEDT and lower IIEF-15 scores than the healthy men (P<0.01). The PEDT score of the PE patients was negatively correlated with their total IIEF-15 score as well as with the scores in the domains of erectile function, sexual intercourse satisfaction, and overall satisfaction after adjusted for age (P<0.01). The patients with acquired PE (APE) showed a lower IIEF-15 score than those with lifelong PE (LPE) (P<0.01). The PEDT score of the APE patients was correlated negatively with the total IIEF-15 score (r=-0.391, P<0.01) and the scores in the domains of erectile function (r=-0.362, P<0.01) and overall satisfaction (r=-0.621, P<0.01), but not correlated with intercourse satisfaction, sexual orgasm, or sexual desire. The PEDT score of the LPE group was correlated negatively with intercourse satisfaction (r=-0.286, P<0.05) but not correlated with either the total IIEF-15 score or the scores in the domains of erectile function, overall satisfaction, sexual orgasm, or sexual desire.</p><p><b>CONCLUSIONS</b>PE patients have a higher PEDT score and a lower IIEF-15 score than normal males. The PEDT score of APE patients is significantly correlated with the total IIEF-15 score, while that of LPE patients is correlated not with the total IIEF-15 score but with intercourse satisfaction.</p>

RESUMO

<p><b>OBJECTIVE</b>To study the effects of oxaliplatin combined with low-molecular-weight citrus pectin (LCP) on cell proliferation and apoptosis in human colon carcinoma cell line HT29 in vitro.</p><p><b>METHODS</b>Effects of oxaliplatin alone and oxaliplatin combined with LCP on HT29 cells proliferation were determined by MTT. Coefficient of drug interaction (CDI) was calculated. Influence of oxaliplatin alone and oxaliplatin combined with LCP on HT29 cell apoptosis was determined by fluorescence activated cell sorting (FACS). Protein expression change of procaspase-3, 8, 9, PARP was examined by Western blotting.</p><p><b>RESULTS</b>Both oxaliplatin alone and oxaliplatin combined with LCP could suppress HT29 cell proliferation in both dose- and time-dependent manner. The inhibitory effect of oxaliplatin combined with LCP on HT29 cell proliferation was more significant (P<0.01) with a CDI less than 1. FACS analysis showed that oxaliplatin alone and combination therapy could increase the apoptosis proportion of HT29 cells. After the drug treatment for 6, 24, and 48 hours, the apoptosis rate of oxaliplatin alone group was (9.76±0.47)%, (20.45±0.74)%, (28.70±3.29)%, and apoptotic rate of the combination group was (20.63±0.69)%, (34.35±1.02)%, (49.47±3.04)%, respectively, which was significantly higher as compared to oxaliplatin alone (P<0.01). Both oxaliplatin alone and combination therapy down-regulated expressions of procaspase-3, 9, and PARP protein. Procaspase-3, 9, PARP protein expression in combination group decreased more significantly, while procaspase-8 expression was not significantly different between the two groups.</p><p><b>CONCLUSION</b>LCP can enhance the ability of oxaliplatin to inhibit cell proliferation and induce apoptosis, which may be associated with the activation of mitochondrial apoptosis pathway.</p>

RESUMO

OBJECTIVES: The aim of this study was to evaluate the diagnostic performance of serum HA and LN as serum markers for predicting significant fibrosis in CHB patients. METHODS: Serum HA and LN levels of 87 patients with chronic hepatitis B and 19 blood donors were assayed by RIA. Liver fibrosis stages were determined according to the Metavir scoring-system. The diagnostic performances of all indexes were evaluated by the receiver operating characteristic (ROC) curves. RESULTS: Serum HA and LN concentrations increased significantly with the stage of hepatic fibrosis, which showed positive correlation with the stages of liver fibrosis (HA: r = 0.875, p < 0.001; LN: r = 0.610, p < 0.001). There were significant differences of serum HA and LN levels between F2-4 group in comparison with those in F0-F1 group (p < 0.001) and controls (p < 0.001), respectively. From ROC curves, 185.3 ng/mL as the optimal cut-off value of serum HA for diagnosis of significant fibrosis, giving its sensitivity, specificity, PPV, NPV, LR+, LR- and AC of 84.2 percent, 83.3 percent, 90.6 percent, 73.5 percent, 5.04, 0.19 and 83.9, respectively. While 132.7 ng/mL was the optimal cut-off value of serum LN, the sensitivity, specificity, PPV, NPV, LR+, LR- and AC were 71.9 percent, 80.0 percent, 87.2 percent, 60.0 percent, 3.59 percent, 0.35 percent and 74.7, respectively. Combinations of HA and LN by serial tests showed a perfect specificity and PPV of 100 percent, at the same time sensitivity declined to 63.2 percent and LR+ increased to 18.9, while parallel tests revealed a good sensitivity of 94.7 percent, NPV to 86.4 percent, and LR- declined to 0.08. CONCLUSIONS: Serum HA and LN concentrations showed positive correlation with the stages of liver fibrosis. Detection of serum HA and LN in predicting significant fibrosis showed good diagnostic performance, which would be further optimized by combination of the two indices. HA and LN would be clinically useful serum markers for predicting significant fibrosis in patients with chronic hepatitis B, when liver biopsy is contraindicated.

RESUMO

<p><b>OBJECTIVE</b>To establish a transgenic cell line with stable expression of CD14.</p><p><b>METHODS</b>Total RNA extracted from peripheral blood mononuclear cells was treated with RNAase-free DNAase, the human CD14 gene was cloned and sequenced through the RT-PCR, T-A clone techniques and ABI PRISM377 machine. Eukaryotic expression vector pcDNA3.1(+)/CD14 was constructed by cleaving with double restriction endonucleases EcoR I/Xba I and ligating with T4 ligase. The human cervical cancer cell line Hela was transfected with the positive recombinant plasmid pcDNA3.1(+)/CD14 using superfect transfection reagent. Positive clones were selected by G418 at a concentration of 0.5 μg/μl and the expression of human CD14 on the transfected Hela cells was confirmed by quantitative PCR and immunofluorescent assay.</p><p><b>RESULTS</b>There was significantly difference om expression of CD14 mRNA between the blank pcDNA3.1(+) transfected cells and pcDNA3.1(+)/CD14 transfected cells (P<0.01). The fluorescence was significantly stronger on the stable cell line Hela-CD14 than that on the transiently transfected Hela cells,and no visible fluorescence was observed in blank vector transfected cells.</p><p><b>CONCLUSION</b>The transfectant cell line Hela-CD14 with stable expression of human CD14 has been successfully established, which can be used to study human CD14 molecular and CD14-associated monocyte/macrophage cell diseases.</p>

RESUMO

<p><b>OBJECTIVE</b>To explore the cytotoxic responses of spleen T lymphocytes (CTL) in BALB/c mice induced by recombinant HSP110-HER2/neu ICD complex.</p><p><b>METHODS</b>Tumor-bearing mouse model was immunized by HSP110-HER2/neu ICD complex. The IFN-γ level secreted by activated spleen T lymphocytes was detected by enzyme linked immunospot assay (ELISPOT). The corresponding CTL activity was measured by granzyme release assay.</p><p><b>RESULTS</b>The BALB/c mouse model of human mammary tumor highly expressing HER2/neu was established. HSP110-HER2/neu ICD complex immunization led to a significantly higher level of INF-γ than that in HSP110-P(789-797) immunized and HER2/neu ICD immunized mice. HSP110-HER2/neu ICD complex immunized animals also show significant CTL activity. The results of immunohistochemical staining showed that the number of blue spots in the PBS group was 4.57 ± 1.33, HSP110 group 6.83 ± 2.08, HER2/neu ICD group 16.17 ± 2.86, HSP110-P(789-797) group 43.67 ± 4.78, and SP110-HER2/neu ICD group 76.51 ± 8.17. The number of IFN-γ-secreting spleen lymphocytes in the HSP110-HER2/neu ICD group was significantly higher than that in the HSP110-P(789-797) group, and that of HSP110-P(789-797) group was significantly higher than that of HER2/neu ICD group (P < 0.01). The target cell-killing rate of the PBS group was (8.15 ± 1.27)%, HSP110 group (9.51 ± 1.51)%, HER2/neu ICD group (14.03 ± 2.45)%, HSP110-P(789-797) group (25.99 ± 3.04)% and HSP110-HER2/neu ICD group (38.15 ± 3.95)% (all P < 0.01).</p><p><b>CONCLUSIONS</b>HSP110-HER2/neu ICD complex can promote the proliferation and maturation of T lymphocytes into CTLs, and might be used as anti-tumor vaccine to induce potent cytotoxic T lymophocyte immunoresponse against specific tumor cells.</p>

RESUMO

<p><b>OBJECTIVE</b>To observe the effects of Fuzheng Huayu Capsule (FHC) on the liver function, HBV DNA quantization, the ratio of transforming growth factor-beta1/bone morphogenetic protein-7 (TGF-beta1/ BMP-7) of peripheral blood mononuclear cells (PBMCs), HBV DNA YMDD variation, and the liver tissue pathology of chronic viral hepatitis B fibrosis patients of Gan-Shen insufficiency blood-stasis obstruction syndrome (GSIBSOS) on the basis of antiviral treatment by lamivudine.</p><p><b>METHODS</b>Eighty chronic viral hepatitis B fibrosis patients of GSBSOS were randomly assigned to two groups. Patients in the control group (43 cases) were treated with lamivudine alone, while those in the treatment group (37 cases) were treated with lamivudine + FHC. The treatment period lasted for 6 months. By the end of treatment lamivudine was continually given to all patients, and patients were followed up for 6 months. Before and after treatment, liver tissue pathology was examined by liver biopsy. The serum HBV DNA quantization, the ratio of TGF-beta1/BMP-7 were determined by fluorescence quantitative polymerase chain reaction (PCR). HBV DNA YMDD variation was tested by the end of follow-ups.</p><p><b>RESULTS</b>Better effects were obtained in decreasing the levels of ALT, AST, and HBV DNA after 6 months of treatment in the two groups, with statistical difference when compared with before treatment in the same group, but with no statistical difference between the two groups. At the end of the 6th month follow-up, YMDD variation occurred in 9 cases of the control group and in 5 cases of the treatment group, with statistical difference between the two groups (P < 0.05). FHC could significantly reduce the ratio of TGF-beta1/BMP-7, significantly lower in the treatment group (0.09 vs 0.25, P < 0.05). In the aspect of liver tissue pathological changes, the rates of inflammatory activity over G3 and fibrosis degree S3 in the treatment group were significantly lower than those in the control group (P < 0.05).</p><p><b>CONCLUSIONS</b>On the basis antiviral treatment of lamivudine for chronic viral hepatitis B fibrosis patients of BSOS, additional application of FHC could lower the HBV DNA YMDD variation, improve the hepatic inflammation and fibrosis, and exert anti-fibrosis by decreasing the ratio of TGF-beta1/BMP-7.</p>

RESUMO

<p><b>OBJECTIVE</b>To study the clinical significance of sequentially monitoring minimal residual disease (MRD) in childhood B-cell acute lymphoblastic leukemia (B-ALL).</p><p><b>METHOD</b>Eighty one B-ALL cases were enrolled in the study from January 2004 to December 2009. Leukemia cell markers were detected by flow cytometry at diagnosis, then regularly followed-up.</p><p><b>RESULTS</b>Of 81 cases, 80 achieved complete remission (CR) after induction therapy, 5-year event-free survival (EFS) was (76.80 ± 5.70)%. Among them, the EFS was (89.40 ± 5.90)% in standard risk group and (66.99 ± 13.60)% in intermediate risk group. Eight cases were screened for leukemia markers for MRD monitoring and identified in 68; and 5-year EFS was (79.10 ± 6.20)% and (62.50 ± 15.10)% (P > 0.05, respectively). MRD detection at day 35 in induction therapy showed that 52 of 68 cases were MRD negative (leukemia cells < 0.01%), the 5-year EFS being (88.50 ± 4.90)%, and 16 were MRD positive (leukemia cells ≥ 0.01%), the 5-year EFS being (42.10 ± 20.10)% (P > 0.05). Univariate analysis confirmed that there was a correlation between MRD monitoring and risk stratification. MRD detection at day 55 showed that among the 52 day 35 MRD negative cases, 51 were still negative, 1 positive, among 16 day 35 MRD positive cases, 14 (87.50%) turned negative, 2 still positive. Of the 68 cases, 9 were MRD positive within one year after CR (3 relapsed), 4 MRD positive after one year (2 relapsed) and 55 MRD negative (4 relapsed) (P > 0.05).</p><p><b>CONCLUSIONS</b>Sequential monitoring MRD can find out treatment outcome and adjust therapy in time.</p>
