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.

Objective: Our aim was to study the relationship between nitric oxide and ovarian neoplasm. The concentrationg of nitrite /nitrate (NO-2/NO-3),glutathione(GSH), and the activity of superoxide dismutase(SOD) were detected in ovarian tissues.Methods:A modified copper-coated cadium reduction method was used to detect NO-2/NO-3. Dithio-bis-nitrobenzoic acid (DTNB) method was used to detect the GSH concentration. The activity of SOD was measured by an ultramicroanalytic and rapid assay. All the data were obtained from 21 patients with ovarian neoplasm(10 with benign ovarian neoplasms,and 11 with ovarian carcinomas). This paper is concerned with the analysis of matched case-control studies. The carcinoma tissues and normal ovarian tissues were obtained from the same patient. We performed Paired-Samples t test to determine whether the NO-2/NO-3,GSH and the activity of SOD in carcinomas and normal ovarian tissues have significantly difference. Results:No significant difference for the concentration of NO-2/NO-3,GSH and activity of SOD was shown in the normal ovarian tissues and neoplasm tissues of benign neoplasm . The concentrations of GSH and activity of SOD in normal ovarian tissues were significantly higher than ovarian carcinomas(P<0.05). No significant difference of concentration of NO-2/NO-3 was shown in normal ovary and ovarian carcinomas. In the normal tissues of all patients, NO-2/NO-3 was positively correlated with GSH and SOD. Glutathione was positively correlated with SOD. In the ovarian neoplasms, there was no significant correlation between NO-2/NO-3 and GSH, NO-2/NO-3 and SOD,GSH and SOD.Conclusion: Nitric oxide and the other matters which attend the course of its metastasis may closely related to ovary neoplasms.

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 compare the renal function after neurosurgery performed under closed-circuit anesthesia with sevoflurane and desflurane and determine the safety of the closed-circuit sevoflurane anesthesia. Methods 36 ASA Ⅰ or Ⅱ patients aged 18-60 years were randomly divided into 2 groups to receive either sevoflurane (group S, n = 18) or desflurane (group D, n = 18) . The duration of surgery was expected to be ≥90 min. The patients were premedicated with intramuscular midazolam 0.07 mg?kg-1 . Anesthesia was induced with midazolam 0.1 mg?kg-1, fentanyl 1.5-2.0 ?g?kg-1 , propofol 1-2 mg?kg-1 and vecuronium 0.1-0.15 mg? kg-1. The patients were mechanically ventilated (VT = 8-12 ml?kg-1) after tracheal intubation. PET CO2 was maintained a 35-45 mm Hg. Fresh gas flow (FGF) was first set at 1-5 L?min-1 for 2-3 min, then reduced to 0.18-0.3 L?min-1. In group D end-tidal desflurane concentration was maintained at 6%-10% ; whereas in group S the end-tidal sevoflurane concentration was maintained at 2.7%-4.0% . BP, HR, ECG, SpO2 PET CO2, inspiratory and expiratory O2 , desflurane and sevoflurane concentrations and the temperature in the center of soda-lime canister were continuously monitored during the operation. Gases were collected from breathing circuit for determination of compound A concentration (by gas chromatography) before anesthesia, at the end of 2-3 min wash-in, every 30 min during maintenance of anesthesia and at the end of anesthesia. Venous blood samples were taken before anesthesia (baseline) , at the end of surgery (T1) and at 2, 24 and 72 h after operation (T2-4) for determination of serum F-, creatinine (Cr) and blood urea nitrogen (BUN) concentrations. Urine specimens were taken for determination of total protein (TP), ?2-microglobulin (?2-MG) and ?-N-acetyl-glucuronidase (NAG) levels, before operation (baseline) at the end of operation and at 24, 48 and 72 h after operation. TP/Cr, ?2-MG/ Grand NAG/Cr were calculated to eliminate the influence of the volume of urine.Results There were no significant differences between the two groups with respect to age, sex, body weight, height, duration of anesthesia and temperature in the center of soda-lime canister. The inspiratory O2 concentration was ≥ 75% during anesthesia. There was no significant difference in serum Cr and BUN concentrations and NAG/Cr in urine before and after operation as well as between the two groups. TP/Cr and ?2-MG/Cr in urine were significantly increased after operation compared to the baseline values but there was no significant difference between the two groups. There was no significant correlation between postoperative TP/Cr, ?-MG/Cr and compound A. Conclusion Closed-circuit sevoflurane ansthesia does not affect postoperative renal function.
