ABSTRACT
The human brain undergoes rapid development during childhood, with significant improvement in a wide spectrum of cognitive and affective functions. Mapping domain- and age-specific brain activity patterns has important implications for characterizing the development of children’s cognitive and affective functions. The current mainstay of brain templates is primarily derived from structural magnetic resonance imaging (MRI), and thus is not ideal for mapping children’s cognitive and affective brain development. By integrating task-dependent functional MRI data from a large sample of 250 children (aged 7 to 12) across multiple domains and the latest easy-to-use and transparent preprocessing workflow, we here created a set of age-specific brain functional activity maps across four domains: attention, executive function, emotion, and risky decision-making. Moreover, we developed a toolbox named Developmental Brain Functional Activity maps across multiple domains that enables researchers to visualize and download domain- and age-specific brain activity maps for various needs. This toolbox and maps have been released on the Neuroimaging Informatics Tools and Resources Clearinghouse website (http://www.nitrc.org/projects/dbfa). Our study provides domain- and age-specific brain activity maps for future developmental neuroimaging studies in both healthy and clinical populations.
ABSTRACT
Objective:To investigate the therapeutic effect of nourishing Yin, clearing heat and detoxifying method combined with hormone and methotrexate on systemic lupus erythematosus (SLE) patients and its immune function.Methods:Sixty-two patients with systemic lupus erythematosus admitted to Third People′s Hospital of Hangzhou from March 2017 to March 2019 were randomly divided into observation group (31 cases) and control group (31 cases) by random number table. The patients in the control group were treated with prednisone and methotrexate, while the patients in the observation group were treated with nourishing Yin, clearing heat and detoxifying method combined with hormone and methotrexate on the basis of the control group. Both groups were treated for 3 months. The therapeutic effects of the two groups were compared, and the changes of complement C3 and C4, immune function before and after treatment were compared.Results:The total effective rate of the observation group was higher than that of the control group [96.77%(30/31) vs.74.19%(23/31)], and there was significant difference ( χ2=6.369, P<0.05). The levels of complement C3 and C4 in two groups before treatment had no significant differences ( P>0.05); after treatment, the levels of complement C3 and C4 in two groups were significantly increased ( P<0.05), and the levels of complement C3 and C4 in observation group were significantly higher than those in control group [(1.08 ± 0.15) g/L vs. (0.81 ± 0.13) g/L, (0.24 ± 0.05)g/L vs. (0.18 ± 0.03) g/L], and there were significant differences ( t=7.574, 5.729, P<0.05). The levels of CD 3+, CD 4+ and CD 4+/CD 8+ in two groups before treatment had no significant differences ( P>0.05); after treatment, the levels of CD 3+, CD 4+ and CD 4+/CD 8+ in two groups were significantly increased ( P<0.05), and the levels of CD 3+, CD 4+ and CD 4+/CD 8+ in observation group were significantly higher than those in control group [(65.72 ± 5.62)% vs. (58.93 ± 4.25)%, (41.03 ± 1.75)% vs.(38.21 ± 1.43)%, 1.65 ± 0.09 vs.1.41 ± 0.12], and there were significant differences ( t=5.365, 6.948, 8.908, P<0.05). The levels of IgA, IgG and IgM in two groups before treatment had no significant differences ( P>0.05); after treatment, the levels of IgA, IgG in two groups were increased, the level of IgM in two groups was decreased, and there were significant differences ( P<0.05). The levels of IgA, IgG in observation group were significantly higher than those in control group [(1.85 ± 0.38) g/L vs. (2.54 ± 0.42) g/L, (12.19 ± 1.63) g/L vs. (14.53 ± 1.37) g/L], and there were significant differences ( t=6.783, 6.119, P<0.05). Conclusions:Nourishing Yin, clearing heat and detoxifying method combined with hormone and methotrexate in treating SLE is effective, which can effectively improve the levels of complement C3 and C4 and immune function.
ABSTRACT
Objective:To investigate the effect of etocoxib combined with colchicine on acute gouty arthritis and its influence on serum uric acid, renal function and inflammatory factors.Methods:From January 2018 to June 2019, 60 patients with acute gouty arthritis in the Third People's Hospital of Hangzhou were divided into treatment group (30 cases) and control group (30 cases) according to the random number table method.The patients in the control group were treated with colchicine, while the patients in the treatment group were treated with etocoxib on the basis of the control group.The course of treatment in both two groups was 7 days.The changes of joint swelling, joint tenderness score, blood uric acid, renal function and inflammatory factors were compared before and after treatment.Results:The total effective rate of the treatment group (90.00%) was higher than that of the control group (63.33%) (χ 2=5.963, P<0.05). The scores of joint swelling[(0.49±0.10)points] and joint tenderness[(0.38±0.09)points] in the treatment group were lower than those in the control group[(0.87±0.15)points and (0.91±0.18)points] ( t=11.545, 14.425, all P<0.05). There was no statistically significant difference in serum uric acid level between the two groups ( t=0.777, P>0.05). There were no statistically significant differences in SCR and BUN between the two groups ( t=0.248, 0.150, all P>0.05). The ESR [(15.21±3.04)mm/h], CRP [(7.06±1.04)mg/L] and IL-1β [(4.17±0.76)pg/mL] in the treatment group were lower than those in the control group [(21.98±3.64)mm/h, (10.94±1.26)mg/L and (6.28±1.08)pg/mL] ( t=7.819, 13.008 and 8.751, all P<0.05). Conclusion:The therapeutic effect of etocoxib combined with colchicine on acute gouty arthritis is obvious, but it has no significant effect on the blood uric acid and renal function, and it can reduce the inflammatory reaction.
ABSTRACT
Objective To investigate the expression of AIF, CYT C, PAF-1, caspase-3, and XIAP in Sprague-Dawley rats with spontaneous mammary neoplasms.Methods One-hundred and thirty 3-4-week old SPF Spargue-Dawley rats (♀∶♂=1∶1) were fed in a specific pathogen free (SPF) breeding barrier for 60 weeks.The occurrence of spontane-ous breast tumors was recorded and histopathology was performed to identify the types of tumors.The rats were divided into 3 groups:rats with normal breast tissue ( group I) , with benign tumors ( group II) and with malignant tumors ( group III) . The expression of AIF, CYT C, APAF-1, caspase-3 and XIAP proteins and mRNAs were detected by immunhistochemistry ( IHC) and RT-PCR assay.Results Among these 130 SD rats, 14 rats were observed having spontaneous mammary neo-plasms with the incidence rate of 10.77%(14/130).In these neoplasm cases, 7 cases were mammary fibroadenomas, 7 cases of breast carcinoma, both with an incidence rate of 5.38%.Immunohistochemistry showed that, compared with the group I, the positive expressions of AIF, APAF-1, caspase-3 were decreased significantly (P<0.01), and the CYT C and XIAP expressions were significantly increased in the group II.The positive expression of all genes except XIAP was de-creased in the group III(P<0.01).Compared with the group II, APAF-1 and XIAP were significantly higher in the group III (P<0.01), and the positive expression of AIF, Cyt C, and caspases-3 were significantly decreased (P<0.01).In the results of RT-PCR assay, except APAF-1 which showed significant correlation with the results of immunohistochemistry ( P<0.05 ) , all the others showed an extremely significant correlation with immunohistochemical results ( P <0.01 ) . Conclusions Mammary tumors are most common spontaneous neoplasms in SD rats.Abnormal expression of mitochondrial apoptotic pathway-related factors AIF, CytC, APAF-1, caspase-3, and XIAP are correlated with the carcinogenesis and de-velopment of breast tumors.
