Objective To explore the clinical and electroencephalography features of children's frontal lobe epilepsy(FLE)and improve the diagnosis and therapy.Methods Medical records were reviewed and neuropsychological evaluations of patients with FLE diagnosed from 2000 to 2006.Children were examined by 24 h EEG and imaging examinations.Their charts for family medical history,seizure,aura,simultaneous phenomenon and anti-epilepic drug therapeutic effects were reviewed.Results Seizures were clonus in 24 cases,tonic in 4 cases,adversive,atonic,vomit in 2 cases,respectively,paresthesia,cephalic,visul,sensory in 1 case,Imaging finding were in 9 of 40.All the 40 cases were bought into 1 to 6 years' follow-up.Long-term control was achieved in 35 of 40.Partial control was achieved in 3 of 40.The left 2 cases had no response to the anti-epileptic drugs.Conclusions The common features of FLE included high seizure frequency,short duration and nocturnal preponderance.There is high positive rate of active EEG in detecting epileptic discharges,and active EEG shoud be necessary.Carbamazepine is recommended to be the first choice to FLE.

OBJECTIVE: To analyze the causes of the esophagogastric junction outlet obstruction (EGJOO) patients, to discuss the differences of the clinical manifestation and esophageal motility characteristics between the anatomic EGJOO (A-EGJOO) and functional EGJOO (F-EGJOO) subgroups, and to search the diagnostic values of the specific metrics for differentiating the subgroups of EGJOO patients. METHODS: For the current retrospective study, all the patients who underwent the esophageal high resonance manometry test were retrospectively analyzed from Jan 2012 to Oct 2018 in Peking University Third Hospital. The EGJOO patients were enrolled in the following research. The clinical characteristics, such as symptoms and causes of the patients were studied. Then the patients were divided into two subgroups as A-EGJOO subgroup and F-EGJOO subgroup. The clinical symptoms and the main manometry metrics were compared between these two subgroups. The significant different metrics between the two groups were selected to draw receiver operating characteristic (ROC) curves and the diagnostic values were analyzed in differentiating the A-EGJOO and F-EGJOO subgroups. RESULTS: The most common symptom of EGJOO was chest pain or chest discomfort (30.63%), then the dysphagia (29.73%), and acid regurgitation/heartburn (27.03%). Non-erosive reflux disease (36.04%) was the most popular cause for EGJOO, then the reflux esophagitis (17.12%). Besides the intra-EGJOO and extra-EGJOO lesions, the connective tissue disease (6.31%) and central nervous diseases (2.70%) were found to be the etiology of EGJOO. The causes of the rest 19 EGJOO were unknown. A-EGJOO patients presented significantly higher intra bolus pressure (IBP) than that of F-EGJOO [6.80 (5.20, 9.20) mmHg vs. 5.10 (3.10, 7.60) mmHg, P=0.016]. The area under curve of IBP was 0.637. When IBP≥5.15 mmHg, the sensitivity was 78.60% and specificity 50.70% to differentiate A- or F-EGJOO. CONCLUSION Chest pain or chest discomfort was the most common symptom in EGJOO patients. Besides the intraluminal structural disorders, the extra-luminal causes were found in EGJOO patients. A-EGJOO presented higher IBP than that of F-EGJOO patients. The cutoff value of IBP to differentiate A-EGJOO from EGJOO was 5.15 mmHg with sensitivity 78.06% and specificity 50.70%. However for the low area under curve, the diagnostic value of IBP was limited.

Suspension cultures cell of Sorbus aucuparia (SASC) was used as materials, the changes of physiological and biochemical indexes of SASC after treatment with yeast extract (YE) were detected, and the synthetic mechanism of secondary metabolites in SASC treated with YE was preliminarily explored. The results were as follows: under the assay conditions, SASC was induced to synthesize five biphenyl compounds, and these compounds content changed differently with induction time prolonging; YE treatment inhibited cell growth, the culture medium pH was gradually reduced after treatment; water-soluble protein content showed a trend of slow decline, which was significantly increased in YE treatment group (YE group) compared with the control group (CK group), the maximum relative content was 147.76% in contrast with CK group; both YE group and CK group were extracellular Ca2+ flow influx, but the YE group flow was significantly slow than CK group. The results indicate that YE induced the cells in a stress state, which was not conducive to the growth of cells and forced the cells to synthesize biphenyl compounds against external stress; water-soluble protein may serve as intracellular enzymes involved in the synthesis of compounds regulation; Ca2+ may as signal molecule mediate cell signal transduction respond to YE stress.

The cardiovascular circulation feedback control treatment instrument (CFCTI) is an automatic feedback control treatment system, which has the function of monitoring, alarming, trouble self-diagnosis and testing on the line in the closed loop. The instrument is designed based on the successful clinical experiences and the data are inputted into the computer in real-time through a pressure sensor and A/D card. User interface window is set up for the doctor's choosing different medicine. The orders are outputted to control the dose of medicine through the transfusion system. The response to medicine is updated continually. CFCTI can avoid the man-made errors and the long interval of sampling. Its reliability and accuracy in rescuing the critical patients are much higher than the traditional methods.

OBJECTIVETo evaluate the sperm quality of college students in Chengdu area.

METHODSA computer assisted sperm analysis (CASA) was made of the sperm concentration, grade A sperm, grade B sperm, sperm viability rate and movement parameters (VCL, VAP, VSL, LIN, STR) of 549 volunteers from 14 colleges in Chengdu area. The volunteers were divided into normal and abnormal groups according to the criteria (sperm concentration > or = 20 x 10(6)/ml, grade A and B sperm > or = 50% or grade A sperm > or = 25%). The results were compared with the data reported in China.

RESULTSAmong the 549 volunteers, the sperm concentration was (50.90 +/- 27.31) x 10(6)/ml, grade A and B sperm was (42.21 +/- 15.38)%, grade A sperm was (29.48 +/- 13.71)%, and the sperm viability rate was (56.40 +/- 14.77)%. The volunteers with normal sperm accounted for 62.84% (345/549) in contrast with abnormal (37.16%, 204/549). Among the 204 volunteers with abnormal sperms, there were 187 (90.67%) with abnormal motility, 39 (19.21%) with abnormal concentration, 22 (10.78%) with both abnormal concentration and abnormal motility. There were no volunteers without sperm. Among the 345 volunteers with normal sperm, the VCL, VAP and VSL were above 25 microns/s, and the VCL, VAP, VSL, LIN and STR were significantly higher than those of the abnormal group (P < 0.01). Moreover, the sperm concentration and the sperm viability rate in 549 volunteers, including 345 volunteers with normal sperm, were lower than the data reported in China.

CONCLUSIONSDue attention should be paid to the sperm quality of the college students in Chengdu area, whose sperm concentration and sperm viability rate have a tendency to decrease.

Introduction:The 2010 targets of the China Hepatitis B Prevention Programme were a prevalence of hepatitis B surface antigen (HBsAg) less than 1.0% for children less than five years old and less than 6.0% for the total population. This survey assessed the prevalence of Hepatitis B infection in Lianyungang, Jiangsu province, China in 2009–2010.Methods:Multistage sampling was used with 2372 subjects among 17 selected villages. Blood specimen collection and testing by enzyme-linked immunosorbnet assay (ELISA) were completed using the following markers for hepatitis infection: HBsAg and antibody to HBsAg (anti-HBs); hepatitis B e antigen (HBeAg) and antibody to HBeAg (anti-HBe); and hepatitis B core antibody (total anti-HBc). The data were analysed with Epi Info, version 3.3.2.Results:The prevalence of HBsAg was 2.4% (95% Confidence Interval [CI]: 1.8–3.0; Adjusted Prevalence [AP] 2.9%); anti-HBs prevalence was 51.1% (95% CI: 49.1–53.1; AP 49.2%) and total anti-HBc prevalence was 41.7% (95% CI: 39.8–43.7; AP 45.5%). The prevalence of HBsAg and total anti-HBc positivity increased from young to older age groups, yet the prevalence of anti-HBs positivity decreased from young to older age groups (P< 0.001 for all). There was no difference in the prevalences of HBsAg and anti-HBs among females and males (P= 0.108 and 0.089), but females had a higher prevalence than males for total anti-HBc positivity (P< 0.001). Discussion: This survey showed that in 2010 the prevalence of HBsAg among children aged less than five years was lower than the national target of 1.0% and that the prevalence of HBsAg for the total population was lower than the national target of 6.0%.
