Electrical status epilepticus during sleep(ESES)is a special electroencephalography in children.It is involved in a variety of epileptic syndromes and can lead to different degrees of degradation of movement, cognition, behavior, language.At present, the cause of ESES is still unknown.According to literature reports, 8 pathogenic genes have been found to be related to ESES, namely GRIN2A, CNKSR2, SCN2A, KCNA2, KCNQ2, KCNB1, SLC6A1 and WAC genes.In this review, progress of ESES molecular genetics are discussed.

Objective To compare the clinical application of endoscope system and dimensional disc hole mirror, and its advantages of percutaneous transforaminal endoscopic discectomy TESSY technology. Methods Two hundred and eighty patients with lumbar disc herniation randomly divided into foraminal mirror group and endoscopic group(140 cases for each groups). Patients in foraminal mirror group were given TESSY removal of nucleus pulposus through lateral approach road,while in endoscopic group were given posterior approach discectomy. The operation time,bleeding volume,postoperative time,incision length,waist and leg waist pain and functional recovery were recorded. Results The operation incision length in foraminal mirror group was(0. 8 ± 0. 1)mm,significantly shorter in the endoscopic group((1. 7 ± 0. 2)mm),the amount of bleeding in foraminal mirror group was( 9. 8 ± 4. 3 )ml,significantly less than the endoscopic group(( 78. 6 ± 18. 8)ml). The above data were statistically significant difference( t =21. 753,19. 280;P ﹤0. 01 ). The getting out of bed time after operation was(0. 3 ± 0. 1)d,significantly earlier than that in the endoscopic group ((3. 5 ± 0. 8)d;t=21. 451;P﹤0. 01). VAS scores of patients in two group at postoperative were(7. 4 ± 1. 8) and(7. 3 ± 1. 6),significantly decreased than that of preoperative((2. 7 ± 1. 7)and(2. 5 ± 1. 6);t=10. 259, 11. 465;P﹤0. 01),But there were no significant differences between the two groups before and after treatment ( P﹥ 0. 05 ). After treatment,waist function recovery in the two groups were 97. 1%( 136/140 ),95. 7%(134/140),and the difference was significant(χ2 =0. 415,P﹥0. 05). Conclusion Foraminal mirror TESSY technique in the treatment of lumbar disc herniation with microendoscopy discectomy with small incision is proved a good approach with less bleeding,postoperative early rehabilitation.

BACKGROUND: Pioglitazone is a common hypoglycemic drug capable of improving proliferation and activation, and inhibiting apoptosis of endothelial progenitor cells (EPCs). We speculated that the combined use of pioglitazone and EPCs transplantation could have significant improving effects on hyperglycemia and kidney function after diabetes mellitus.OBJECTIVE: To investigate the improving effect of EPCs transplantation combined with pioglitazone treatment on the kidney function of diabetic rat models.METHODS: The 15 of 75 Wistar rats were randomly selected and served as normal control group (no treatment). Animal models of type 1 diabetes mellitus were made in the rest 60 rats through the intraperitoneal injection of 40 mg/kg streptozotocin for continuous 5 days. The human EPCs (labeled by CM-Dil) were recovered, cultured and preserved until transplantation. After 4 weeks of modeling, the 60 rat models were randomly divided into model group (PBS injection), pioglitazone group, EPCs transplantation group and combined treatment group, followed by tail vein injection of EPCs suspension and/or intragastric administration of 20 mg/kg pioglitazone for continuous 4 days. After 8 weeks of treatment, the levels of glucose, insulin and creatinine in serum, urea nitrogen and urine protein during 24 hours were determined. The number and distribution of EPCs labeled by CM-Dil were detected by fluorescence microscope, the apoptosis in kidney cells was tested by TUNEL method, and the kidney weight/body weight ratio in rats was calculated.RESULTS AND CONCLUSION: Compared with the model group, the blood glucose and serum creatinine levels and the urea nitrogen and urine protein concentrations during 24 hours were significantly decreased (P < 0.05), and the seruminsulin level was significantly increased (P < 0.05) in the pioglitazone and EPCs transplantation groups. These biochemical indexes in the combined treatment group were more significantly altered compared with the model group (P< 0.01). The kidney weight to the body weight ratio was lowest in the combined treatment group and lower in the pioglitazone and EPCs transplantation groups followed by the model group (P < 0.05). The order of apoptotic kidney cells labeled by TUNEL was as follows: model group > pioglitazone group > EPCs transplantation group > combined treatment group (P < 0.05). To conclude, the EPCs transplantation combined with pioglitazone treatment can decrease the blood glucose and serum creatinine levels and urea nitrogen and urine protein concentrations, improve the serum insulin level, reduce cell apoptosis in the kidney, and remit the kidney dysfunction of diabetic rats to a certain extent.

Recombinant plasmids pHY-PA, pBBR-PA were constructed in which genes pdc and adhB were placed under the control of tac promoter, respectively, and had successfully expressed in Escherichia coli. Then these recombinant plasmids were electroporated into Lactobacillus strains for ethanol production. Preliminary ethanol fermentation using these Lactobacillus strains and their recombinants was carried out using 42℃ as fermentation temperature. The results indicated that introducing pdc and adhB, ethanologenic pathway was successfully constructed in L.plantanum CICIM B0080. 0.4% (V/V) ethanol was detected at the end of fermentation with 6.7% glucose, and that is 67-fold as the wild-type B0080. Two-fold of ethanol production was detected in L.amylovorus B0112 (pHY-PA) and L.acidophilus B0068 (pBBR-PA). Introducing both pdc and adhB, and meanwhile knock-outing the lactate dehydrogrnase gene may better convert carbon flux to ethanologenic direction.

Objective To investigate the healing mechanism of the rabbit's selerotomy sites undergoing the transconjunctival su- tureless vitrectomy(TSV),and to compare the wound healing effect of the different surgery procedures.Design Experimental study. Participants New Zealand white rabbits.Methods Thirty-two New Zealand white rabbits were divided into four groups:the core vitrec- tomy and fluid-air exchange (Group A),the core vitrectomy (Group B),the non-core vitrectomy and fluid-fir exchange (Group C) and the non-core vitrectomy(Group D).Intraocular pressure(IOP)was measured on the day preoperatively and the day 1,3,5,7,14 postopera- tively with Tonopen tonometers.Sclerotomy sites were investigated with the ultrasound biomicroscope(UBM)on the day 1,5 and 9 postoperatively,and the internal and the external diameter of the wound was estimated on the day 1 postoperatively.The pathological sections of the sclerotomy sites on the day 3,5 and 9 postoperatively were observed under the light microscope.Main Outcome Mea- sures IOP,the internal and external diameter of the wound.Results The IOP of Group A was obviously higher than the other groups on the day 1 postoperatively (P

Objective To investigate the regulation of parathyroid hormone(1-34) on mRNA expression of osteoclast inhibitory lectin (OCIL) gene in UMR106 osteoblastic-like cells and involved signaling pathway.Methods Rat UMR106 osteoblastic-like cells were cultured and treated with various concentration of PTH(1-34) and specific agonists or inhibitors of PKA,PKC,Ca2+/calmodulin-dependent protein kinase (CaMK) and mitogen-activated protein kinase (MAPK) signal pathways for indicated time intervals.Then the cells were gathered at indicated time points and total RNA were extracted.OCIL mRNA expression was analyzed using real-time PCR technique.Results PTH(1-34) stimulated OCIL mRNA expression in a time-and dose-dependentmanner.A dose of 10 nmol/L PTH(1-34) started to induce OCIL mRNA from 6 h,with a highest increase of about 2.8-fold vs.control group (without PTH treatment) at 24 h.The up-regulation of OCIL mRNA began and reached maximum later than RANKL induction and OPG suppression effected by PTH(1-34).Protein Kinase A (PKA) signaling activators forskolin(FSK) and dibutyryl cAMP (db-cAMP),as well as calcium ionophore A23187 all up-regulated OCIL mRNA with the maximal induction of about 4.2-fold,4.5-fold and 5.1-fold.Protein Kinase C (PKC) activator phorbol-12-myristate-13-acetate(PMA) reduced OCIL mRNA expression at the early stage(2-6 h),with the highest down-regulation of 50％ at 6 h.However,the inhibitory effect on OCIL mRNA turned into slightly stimulatory effect later (24 h).PKA inhibitor KT5720,calmodulin antagonist W-7,CaMK Ⅱ inhibitor KN-62 and mitogen-activated protein kinase (MAPK) inhibitor PD98059 all blocked PTH(1-34)-induced OCIL mRNA expression by the maximal reduction of 56％,61％,63％ and 50％ respectively.There also exist cross-talks between different signal pathways.MAPK inhibitor PD98059 blocked the expression of OCIL mRNA which was stimulated by PKA activators FSK or db-cAMP,with the reduction of 98％ and 63％ respectively,while the OCIL mRNA expression stimulated by A23187 remained unaffected.Conclusion PTH(1-34) increased OCIL mRNA expression in vitro through cAMP/PKA,Ca2+/CaMK and MAPK signaling pathways.
