To investigate the effect of OGT expression inhibited by RNAi on the alteration of tau phosphorylation and glycosylation level in HEK293T cells.The siRNAs targeting OGTgene(OGT-siRNA1~3) were designed and chemically synthesized.The OGT-siRNA1~3 were transfected into HEK293T cells via lipofectamine2000.The efficacy of RNA interference was detected by RT-PCR.The fluorescence of GFP/OGT was counted by fluorescence microscopy after pEGFP/OGT and OGT-siRNA1~3 cotransfected to HEK293T cells for 24 h.The level of tau phosphorylation and glycosylation were detected by Western blot after Plasmid pCI/tau441 and the siRNA cotransfected HEK293T cells for 48 h.OGT-siRNA3(100 nmol/L) could effectively downregulate the expression of OGT gene compared with Mock group(80.0% at mRNA level and 51.3% at protein level).The level of phosphorylation at various sites of the tau was significantly upregulated and the glycosylation was downregulated following the inhibition of OGT gene expression.There is an apparent negative correlation between the modification of phosphorylation and glycosylation of tau protein, the deficient in glucose uptaken/metabolism may be an important pathogenesis of AD.

OBJECTIVE:To investigate the protective effects of insulin-glucose on myocardium in patients receiving cardiac valve replacement under cardiopulmonary bypass. METHODS:Totally 120 patients receiving combined cardiac valve replacement under cardiopulmonary bypass were divided into control group and observation group according to random number table,with 60 cases in each group. All patients were given routine operation. Control group was given Thomas cardioplegia and oxygenated blood with a ratio of 1:4(V:V)to protect myocardium at 4 ℃. Besides that,the observation group was additionally given Insulin injec-tion 10 IU/L and Glucose injection 10 g/L added into Thomas cardioplegia at 4 ℃ to protect myocardium. The levels of plasma brain natriuretic peptide(BNP)and cardiac troponinⅠ(cTnⅠ)before anesthesia induction(T0),at the end of cardiopulmonary by-pass(T1),12 h(T2),24 h(T3),48 h(T4),and 72 h(T5)after surgery,the rate of recovery of automatic heartbeat after opening aor-ta,the application of vasoactive agent(dopamine)at T1 and the occurrence of postoperative complications were observed and com-pared between 2 groups. RESULTS:At T0,there was no statistical significance in the levels of plasma BNP and cTnⅠ between 2 groups(P>0.05). The levels of plasma BNP and cTnⅠin 2 groups at T1-5 were significantly higher than T0,with statistical signifi-cance(P<0.05);the levels of cTnⅠ began to decrease at T4 and cTnⅠbegan to decrease at T5. However,the levels of BNP and cTnⅠwere significantly lower in observation group than in control group at T1-5,with statistical significance(P<0.05). After open-ing aorta,there was no statistical significance in the rate of recovery of automatic heartbeat between 2 groups(P>0.05). The dos-age of dopamine (at T1) and the incidence of complications in observation group were statistically lower than control group,with statistical significance(P<0.05). No severe ADR was found in 2 groups during or after surgery. CONCLUSIONS:Insulin-glucose can alleviate myocardial damage, reduce the dosage of vasoactive agent and the incidence of postoperative complications in pa-tients receiving combined cardiac valve replacement under cardiopulmonary bypass with significant protective effect on myocardium with good safety.

Objective:To compare the difference of serum levels of M-phospholipaseA2 receptor ( PLA2R) antibodies in patients with idiopathic membranous nephropathy(IMN) detected by two different methods and evaluate the diagnostic value of two methods. Methods:Patients diagnosed as membranous nephropathy and other diseases with biopsy-proven from december 2014 to october 2015 in Shengjing Hospital of China Medical University were enrolled and devided into IMN group and non-IMN group. The serum levels of anti-PLA2R antibody were detected by both indirect immunofluorescence assay(IFA) and enzyme linked immunosorbent assay(ELISA). Results:The sensitivity of IFA and ELISA in IMN were 71. 3% and 68. 5%,and the specificities of two methods were the same as 100%. The area under ROC curves of anti-PLA2R antibody for IMN diagnosis were 0. 860 and 0. 839. The diagnostic value of IFA and ELISA was no statistically significant differences in IMN ( P>0. 05 ) , and the consistency of two methods was better (κ=0. 876). The IMN patients of positive anti-PLA2R antibody be susceptible to the low level of serum albumin (P<0. 05). The higher levels of PLA2R antibody were linked with the worse hypoproteinemia and the higher rate of nephrotic-range proteinuria in IMN patients. Conclusion:Two methods of detecting sera PLA2R antibody have higher sensitivity and specificity,so the sera anti-PLA2R antibody was a better biomarker in the diagnosis of idiopathic membranous nephropathy.

The true meanings of the terms of traditional Chinese medicine (TCM) need to be analyzed on a logical basis. It is not suitable to use a new term to interpret an old term of TCM, or arbitrarily specify the special term of TCM corresponding to some substances of modern medicine. In philosophy of language, language has a logical structure, which reflects the structure of the world, that is to say, language is the picture of the world in a logical sense. Using this idea, the authors collected the ancient literature on "kidney essence", and extracted each necessary condition for "kidney essence". All necessary conditions formed a sufficient condition to define the term "kidney essence". It is expected that this example can show the effectiveness of philosophy of language in analysis of the terms of TCM.

Objectives To analyze the clinical characteristics and signiflcance of Mycoplasma pneumoniae pneumonia (MPP) combined with secondary thrombocytosis in infants and young children. Methods Clinical features, laboratory and imaging data of the infants and young children with MPP were collected, and compared between the two groups of children with and without secondary thrombocytosis. Results Sixty-seven (67) infants and young children with secondary thrombocytosis (28 males and 39 females, with onset at 2 years and 2 months after birth in average) and 269 infants and young children with normal platelet counts (138 males and 131 females, at 2 years and 3 months after birth in average) were included. Signiflcant longer durations of hospitalization(P =0.018) and fever(P =0.000), higher temperature peak(P =0.000), as well as higher morbidity of refractory MPP(P =0.001) and more complications(P =0.000)were observed in the group of MPP with secondary thrombocytosis. Moreover, the laboratory data of white blood cell count(P =0.000), C-reactive protein(P =0.000),procalcitonin (P =0.000), erythrocyte sedimentation rate(P =0.000)and higher morbidity of multiple pathogen infection(P =0.033) were observed between the two groups.Conclusions More severe clinical manifestations and higher complication morbidity could be observed in the group of MPP combined with secondary thrombocytosis, implicating the value of platelet count in clinical assessment of MPP in infants and young children at early stage.

Objective To observe the serum VEGF/ES ratios before and after operation and at clinical relapse in patients with breast cancer, and to discuss the potential effect of tumor surgery and postoperative relapse on the angiogenesis balance. Methods The serum VEGF and ES levels of 59 cases of breast cancer before and after operation and at clinical relapse were determined using competitive enzyme immunoassays and ELISA, (respectively), and compared with the results of 30 cases of benign breast tumors and 59 cases of normal (controls). Results (1) Preoperatively, the serum ES and VEGF levels of breast cancer patients were (significantly) elevated, as compared to the other 2 groups, and the VEGF/ES ratio was 9.1. Postoperatively, at 3 weeks, VEGF level decreased significantly and ES remained at a high level. The VEGF/ES ratio was (3.3). (2)At the time of clinical relapse, serum VEGF level was followed by marked elevation, and the VEGF/ES ratio increased up to 14.2. Multivariate analyses showed that the postoperative VEGF/ES ratio was an independent factor related to the postoperative recurrence of breast cancer. Conclusions Breast cancer surgery may affect the balance between serum VEGF and ES, and the determination of VEGF/ES ratio can have auxiliary value in the assessment of prognosis of breast cancer patients.
