Objective To investigate the life quality of children with intractable epilepsy and observe the effect of psychological intervention on them.Methods Thirty-nine children with intractable epilepsy,42 children with drug respond epilepsy and 40 healthy children were employed and tested by using of the child self-report scale of quality of life for children with epilepsy.Scores of quality of life were compared among 3 groups.Children with intractable epilepsy were divided randomly into 2 groups:psychological intervention group(19 cases)and non psychological intervention group(20 cases).Only drug treatment was given in non psychological intervention group,drug treatment and psychological intervention were given in psychological intervention group,quality of life was valuated before and 1 month after psychological intervention,then scores of quality of life were compared after and before psychological intervention in psychological intervention group,total scores of quality of life were compared between psychological intervention group after and before psychological intervention and non psychological intervention group.Results Compared with children with drug respond epilepsy and healthy children,the children with intractable epilepsy had lower scores of quality of life(Pa

Tumor cells can metabolize glucose through glycolysis to intermediates for biomacromolecule synthesis by inhibiting the activity of the pyruvate dehydrogenase complex (PDC) in mitochondria. In this process, pyruvate dehydrogenase kinases (PDKs) play a key role. The inhibition of the activity of PDKs can effectively block this metabolic pathway, activate mitochondrial oxidative metabolism, and induce tumor cell apoptosis. PDK inhibitors have become a research hotspot in medicinal chemistry, and novel structures targeting classical binding sites have been synthesized. In this paper, recent research progress on PDK inhibitors is reviewed to provide information on these latest entities and to explore their clinical applicability.

OBJECTIVETo investigate the role of endogenous hydrogen sulfide (H2S) in erectile dysfunction (ED) induced by androgen deficiency.

METHODSWe randomly divided 30 eight-week-old healthy male SD rats into six groups: 2-week control (A), 4-week control (B), 2-week castration (C), 4-week castration (D), 2-week castration + androgen replacement (E), and 4-week castration + androgen replacement (F), those in groups E and F subcutaneously injected with testosterone propionate (TP) at the physiological dose of 3 mg/kg per day after castration, while those in the other groups with isodose oil instead. At 2 and 4 weeks after operation, we determined the level of serum testosterone (T) , intracavernous pressure (ICP) , mean carotid arterial pressure (MAP) of the rats, measured the concentration of H2S in the plasma and corpus cavernosum tissue, and detected the expressions of cystathionine-P3-synthase (CBS) and cystathionine-gamma-lyase (CSE) by immunohistochemistry and Western blot.

RESULTSThe serum T level was significantly lower in group C ([0.63 +/- 0.15] nmol/L) than in A ( [ 16.55 +/- 4.17] nmol/L) and E ( [ 18.99 +/- 4.62] nmol/L) (P <0.05), as well as in group D ([0.70 +/-0.22] nmol/L) than in B ([15.44 +/-5.18] nmol/L) and F ([20.99 +/-6.41] nmol/L) (P <0. 05) , and so were ICP/MAP after 5 and 7 V electrical stimulation of the pelvic ganglia (P <0. 05) , H2 S concentration (P <0.05), and the expressions of CBS and CSE (P <0.05). The expressions of CBS and CSE proteins were also significantly decreased in group C as compared with D (P <0.05).

CONCLUSIONThe reduced expressions of CBS and CSE may inhibit the H2 S signaling pathway, which might be one of the mechanisms underlying androgen deficiency-induced ED in rats.

Objective To explore the changes of high-sensitivity C reactive protein(hs-CRP) and platelet parameter levels in newborns with hypoxic-ischemic encephalopathy(HIE)and its clinical significance.Methods Thirty-five infants with HIE and 16 healthy newborns were selected as study cases and controls respectively by automantc biochemistry analyzer.Serum hs-CRP content was measured by reaction rate method;Platelet parameter levels were detected by collecting blood samples from peripheral vascular of heel,and the activity of creatine kinase(CK),creatine phosphokinase isoenzyme(CK-MB),lactate dehydrogenase(LDH),alpha-hydroxybntyric dehydrogenase(?-HBDH),alanine transaminase(ALT),aspartate aminotransferase(AST) were assayed as well.Results 1.The hs-CRP levels in newborns with HIE increased obviously in acute stage,and significant difference were observed compared with controls(P0.05).2.PLT in newborns with HIE decreased significantly in acute stage compared with that of controls(P0.05).3.The values of CK,CK-MB,LDH,?-HBDH,AST,ALT in newborns with HIE were significantly higher than those in controls in acute stage(P

Objective To evaluate the role of gliocytes in the spinal cord in the development of inflammatory pain (IP) in rats. Methods Adult male SD rats weighing 180-220 g were used in this experiment. A catheter was implanted in the subarachnoid space according to the method described by Yang. Animals with abnormal motor function of the hindlimb after intrathecal (IT) catheter implantation were excluded. IP was induced by subcutaneous (sc) injection of complete Freund's adjuvant (CFA) 50 μl at the lateral side of the ankle joint of the right hindpaw. Sixty-five rats were randomly divided into 5 groups ( n = 13 each): group I IP control normal saline (NS) 50μl was injected sc instead of CFA; group II IP; group IE PC (IT) + IP control fluorinated citric acid (FC, a gliocyte metabolism inhibitor) 1 nmol/10μl was injected IT at 15 min before NS 50 μl sc injection; group IV NS (IT) + IP and group V FC (IT) + IP. The mechanical paw withdrawal threshold (MWT) and thermal paw withdrawal latency (TWL) were measured 2 d before induction of IP (T_0, baseline) .before and at 2, 4, 6, 8, 10, 12, 24 and 26 h (T_(1-9)) after sc NS or CFA injection. Five enimals in each group were killed at T_5 (8 h after sc NS/CFA injection) and the lumbar segment (L_(4,5)) was removed for determination of glial fibrillary acidic protein ( CFAP) and OX-42 expression by immuno-histochemistry. Results In group Ⅱ and Ⅳ sc CFA significantly decreased MWT and TWL. Mechanical and thermal hyperalgegia induced by sc CFA was significantly suppressed by intrathecal FC in group V . IP significantly increased GFAP and OX-42 expression in the spinal cord. Intrathecal FC significantly attenuated IP-induced up-regulation of GFAP and OX-42 expression in the spinal cord. Conclusion The activation of gliocytes in the spinal cord is involved in the development of CFA-induced hyperalgesia in rats.
