Objective To investigate the clinical and electroencephalogram (EEG) characteristics of children with electrical status cpilepticus during sleep (ESES), and the response to medication therapy. Methods AEEG and VEEG including an entire sleeping c-ycle were performed on 26 patients with ESES. The clinical and EEG changes, neuropsychological impairment and the response to medication therapy were followed up. Results Twenty five patients had seizures,21 cases had normal psychomotor development before ESES. After the onset of the disease,Fifteen cases developed language disorder, 16 cases developed psychological and behavior abnormalities, 13 cases had both of the problems Seventeen patients belonged to epileptic syndrome. Patients in this cohort had good response to clonazepam and valproate treatment. Cortical steroid could dispel the electrical discharge. Eighteen patients had been followed up. Seizures stopped in 15 cases after treatment ESES disappeared in 16 cases, 4 of them still had neuropsychological impairment ESES sustained in 2 cases Conclusions ESES is a specific EEG phenomenon. Continue epileptic form discharge during non - rapid cye movement sleep is the major cause of neuropsychological impairment in patients with ESES. To control the seizures and electrical state are very important for the prevention and treatment of neuropsychological impairment.

Objective:To investigate the efficacy of the combined application of fluconazole and sodium bicarbonate in treatment of oral fungal infections among elderly patients with acute exacerbation of chronic obstructive pulmonary disease (AECOPD).Methods:A total of 360 elderly patients with AECOPD treated in the Emergency Ward of our hospital during July 1, 2018 and December 31, 2019, were included for observation. After admission, the oral mucosal lesions were observed every day, and fungal smear and fungal culture were performed immediately once signs of fungal infection appeared. Meanwhile, fluconazole was given with 300 mg. oral. qd., followed by 150 mg. oral. qd., and 2.5% sodium bicarbonate was given three times a day as gargle.Results:The prevalence of oral fungal infection was 8.3% among which candida infection accounted for 83.2%. The mean treatment time was 5.0 ± 0.3 days. Daily observation of the oral cavity, early detection and application of fluconazole combined with sodium bicarbonate had significantly clinical effect in elderly AECOPD patients with oral fungal infection, with an effective rate of 16.7%, and a cure rate of 83.3%. No toxic side effects on liver and kidney function were found during the treatment. Obvious efficacy was found in relieving clinical symptoms, and there was no increase in hospitalization costs and time.Conclusion:Early combination of fluconazole and sodium bicarbonate has a significant clinical effect on control of oral fungal infection in elderly patients with AECOPD.

The poly(ethylene glycol)-lipid derivatives were synthesized for constructing pH-sensitive liposomes. The polyethylene glycol polymer MePEG2000-NH2 and phospholipids POPA were connected by phosphorus-amide linkage. The poly(ethylene glycol)-lipid derivatives acidic sensitive liposomes were prepared. Factor effects on polymer insertion into liposomes were evaluated and the pH-sensitivity of the polymer associated liposomes were studied by calcein release assay. The poly(ethylene glycol)-lipid derivatives acidic sensitive liposomes were prepared successfully by the extruding linkage device. The liposomes constructing by poly(ethylene glycol)-lipid derivatives was stable at pH 6.5-7.5, the stability was closely related to phospholipid types and cholesterol content of the preparation of liposomes. At pH 5.0 occurred when divulging fluorescence occurred obviously, the leakage rate and the strength was with a positive correlation between time of in the acidic environment and intensity of acid. The acidic sensitive liposomes prepared by poly(ethylene glycol)-lipid derivatives were developed as a potential pH sensitive delivery system.

Objective To study the expressions of foliate binding protein 1(Folbp1),Wnt and ?-catenin genes on the heart of offspring during the development of embryo,whose mother was deficient of folic acid.Methods Control group involving 18 rats and study group involving 18 rats were choosen from the total 36 adult female SD rats randomly copulate with the male normal rats after feeding different fodder for 2 weeks.The heart of the 13.5,17.5 days embryos and the newborns were obtained.The expressions of Folbp1,Wnt and ?-catenin genes mRNA at the 3 periods were evaluated by RT-PCR.Results The expressions of Folbp1,Wnt and ?-catenin genes mRNA of the study group were significantly weaker than those of the control group in heart of the 13.5,17.5 days embryos and the newborns(all P

Seven compounds were isolated from Onychium japonicum by macroporous resin, silica gel, ODS, Sephadex LH-20 column chromatography and semi-preparative HPLC. Their structures were identified by NMR, MS and other spectroscopic methods as onychone A (1), quercetin (2), quercetin-3-O-α-L-rhamnoside (3), kaempferol-7-O-β-D-glucopyranoside (4), kaempferol-3-O-α-L-rhamnopyranoside (5), (-)-prunin (6), and norathyriol (7). Compound 1 is a novel macrocyclic flavonoid, and all the others are reported from this plant for the first time. In vitro cytotoxic activities of compounds 1-7 were evaluated by MTS testing with five cancer cell lines. Compound 7 exhibited weak cytotoxicity against tumor cell lines A549, SMMC-7721, and SW480.

OBJECTIVETo explore the molecular mechanism of Qiangxin Fumai granule (QFG, an effective Chinese composite drug) in preventing and treating sick sinus syndrome (SSS).

METHODRabbit model of sinoatrial ischemia/reperfusion was established by occluding and loosening the root of right coronary artery. Effect of QFG on cell apoptosis was observed by TUNEL method, and its effect on apoptotic related gene Bax, Bcl-2 and Fas-L gene protein expression was observed by immunohistochemical method. Average light density values of the expression of Bax, Bcl-2 and Fas-L of SAN cells was determined by Imagepro Plus image analysis system.

RESULTSinoatrial injury induced by ischemia/reperfusion could cause evident sinoatrial cell apoptosis, enhance Fas-L gene protein expression and obviously enhance Bax gene protein expression, reduce Bcl-2/Bax ratio. QFG could significantly down-regulate Fas-L and Bax gene protein expression, up-regulate Bcl-2/Bax ratio, significantly inhibit and block the sinoatrial cell apoptosis.

CONCLUSIONTo inhibit and block the event of cell apoptosis through regulating Bax, Bcl-2 and Fas-L gene protein expression in sinoatrial node after ischemia/reperfusion might be one of the mechanisms of QFG in preventing and treating sinoatrial ischemia/reperfusion injury of SSS.
