Objective To observe effects of Kangshuai Yizhi Capsule on ATP in brain tissue and IL-6, TNF-α in serum of aging model rats, and explore the protective effects of the capsule on brain tissue.Methods Totally 72 rats were randomly divided into a normal group and a model group. The subacutely aging model rats were made by injectingD-gal, then aging rats were numbered and grouped by random number table into the model group, Kangshuai Yizhi high-dose group, Kangshuai Yizhi Capsule low-dose group and Naofukang group. All dose groups were received gavage by giving corresponding doses, while normal group and model group were given the same amount of saline everyday. After treated for 60 days, the activity of Na+-K+-ATP and Ca2+-Mg2+-ATP in brain tissue, and IL-6, TNF-α in serum were detected.Results Compared with normal group, Na+-K+-ATP and Ca2+-Mg2+-ATP were less active (P<0.05), but levels of IL-6 and TNF-α in model group were significantly higher, with statistical significance (P<0.05). Compared with model group, after treated with Kangshuai Yizhi Capsule, Na+-K+-ATP and Ca2+-Mg2+-ATP were more active, and IL-6 and TNF-α levels were down-regulated significantly in dose groups, with statistical significance (P<0.05). Meanwhile, Kangshuai Yizhi Capsule high-dose group showed the most obvious effect among dose groups.ConclusionKangshuai Yizhi Capsule has effects of enhancing activity of ATP in brain tissue and reducing level of proinflammatory factors.

Objective To investigate the clinicopathological significances of LDHA/mutant p53 co-expres-sion in gliomas. Methods According to the 2016 WHO CNS,archived 68 gliomas were collected and analyzed retrospectively. The co-expression of LDHA/mutant p53 was detected by immunohistochemical staining. Results High expression of LDHA alone was always found in high grade gliomas(48.5%). Mutant p53 high expression was usually observed in glioblastomas (26.5%). There was a close relationship between co-expression of LDHA/mutant p53 in glioblastoma(27.9%,P = 0.005),or gliomas with high histological grading(27.9%,P = 0.002). Conclusions Co-expression of LDHA/mutant p53 in tumor cells might be a specific immunohistochemical pheno-type of gliomas,and may help for distinguishing glioblastoma and other high grade gliomas from low grade gliomas.

Objective To analyze the clinical characteristics of 110 cases of infectious mononucleosis in children. Methods The clinical data of 110 children with infectious mononucleosis in the period from January 2015 to January 2018 were analyzed retrospectively. Results The 110 patients included 74 males(67.3%)and 36 females(32.7%). The male to female ratio was 2.1:1.The age distribution: 2~<3 years old, 29 cases(26.4%); 3-6 years old, 67 cases(60.9%);>6-13 years old, 14 cases(12.7%).The main symptoms and signs included fever in 101 cases(91.8%), pharyngitis in 100 cases(90.9%), lymphadenomegaly in 95 cases(86.4%), eyelid edema in 79 cases(71.8%), splenomegaly in 55 cases(50.0%), and liver enlargement in 37 cases(33.6%).The complications were pneumonia in 61 cases(55.5%), myocardial damage in 53 cases(48.2%), neutropenia in 35 cases(31.8%), and thrombocytopenic purpura in 4 cases(3.6%). The prevalence of IgM antibody against Epstein-Barr virus capsid antigen was43.6%. The prevalence of IgM antibody against Epstein-Barr virus early antigen was 31.8%. The positive rate of IgG antibody against Epstein-Barr virus nuclear antigen was 56.4%. The prevalence of atypical lymphocytes in peripheral blood was 46.4%.Conclusions Infectious mononucleosis in children is more common in males and during the period from 3 to 6 years of age. The clinical symptoms include pneumonia and myocardial damage. Epstein-Barr virus detection and serological assay are helpful for diagnosis.

To explore the mechanism for the role of autophagy in endometriosis, and to provide a theoretical basis for prevention and treatment of endometriosis.
Methods: The endometrial CRL-7566 cells were treated with ATG5 siRNA, autophagic activator rapamycin and autophagic inhibitor 3-MA, respectively. The cell proliferation and invasion were detected by clonal formation, cell growth curve and MTT assay. The clinical specimens of endometriosis were collected from 20 cases. The expression of autophagy marker LC3II and autophagy substrate protein P62 were detected.
Results: Rapamycin inhibited the proliferation and clonal formation of CRL-7566 cells, while autophagy inhibitor 3-MA and ATG5 siRNA showed opposite effect. Moreover, rapamycin inhibited filopodia growth in endometriosis, whereas overexpression of filopodia-relevant protein fascin-1 inhibited the decrease in invasiveness caused by rapamycin. In clinical samples, we also found a significant decrease of LC3II while an increase in P62 compared with the control group.
Conclusion: Autophagy inhibition may contribute to an increase in endometrial cell proliferation and invasiveness. Autophagy activation could be a potential strategy for endometriosis therapy.
