Objective To analyze the changes of the urine sodium and serum sodium in different types and different duration and different temperature in children with febrile seizures,to explore its clinical significance. Methods The children with febrile seizures(n =50)were selected as the group Ⅰ,and the children with fever but without seizure(n =50)were selected as the group Ⅱ,both of them were from pediatric ward.The control group(n =20)without fever or seizure was from Children's Health Section.All the children were checked serum sodium level and urine sodium and urine creatinine level.Results The sodium/creatinine ratio in the groupⅠ[(25.07 ±6.517)] was significantly higher than that in the group Ⅱ[(20.43 ±5.48)]and group Ⅲ[(14.88 ±5.11)](F =33.519, P <0.05),but there was no significant difference of the sodium/creatinine ratio in different ages and different types of the group Ⅰ,and there was negative relevance between the serum sodium and the sodium/creatinine ratio in the groupⅠ(r =-0.517,P <0.05).The mean serum sodium level in the groupⅠ[(133.50 ±3.14)mmol/L]was signifi-cantly lower than that in the group Ⅱ[(137.60 ±2.59)mmol/L]and group Ⅲ[(138.90 ±2.24)mmol/L](F =39.220,P <0.05),but there were no significant differences of the serum sodium in different types and different dura-tion and different temperature of seizure in the group Ⅰ.Conclusion The study shows that serum sodium is lower and the urine sodium is higher in children with febrile seizures,the changes of the urine sodium and serum sodium are not related to the types.The children with febrile seizures should be timely monitoring of serum sodium,urine sodium levels,and according to changes in the level of serum sodium,urine sodium,early appropriate supplement containing sodium liquid and maintaining the blood sodium to normal levels can reduce the recurrence of seizure.

Objective To study the character and clinical significance of electrolyte in the children suffered from different degree pneumonia on different periods. Methods The levels of sodium, calcium, magnesium, potassium, chlorine and phosphorus in the serum of children suffered from mild pneumonia group, severe pneumonia group and control group were tested respectively. The levels of sodium, calcium, magnesium in the serum of children suffered from pneumonia during their acute period and convalescence were tested respectively. The levels of potassium in the serum of children suffered from pneumonia caused by various pathogens were detected too. Those results were analysed. Results The levels of sodium, calcium, magnesium in the serum of children in mild pneumonia group were obviously higher than those in severe pneumonia group(P

This paper introduces an adaptive filter method for enhancing ventricular late potentials. The adaptive filter has only one signal electrode and does not need the reference electrode. The experiment results show that this adaptive filter method can effectively improve signal-to-noise ratio of ventricular late potentials.

OBJECTIVETo demonstrate the clinical applicability of three-dimensional CT angiography by evaluating the anatomic features and variation of inferior mesenteric artery(IMA) and left colic artery(LCA) in order to provide reference to vessel ligation strategy in laparoscopic rectal cancer surgery.

METHODSClinical and image data of 123 patients receiving abdominal multislice CT at The Sixth Affiliated Hospital from 2014 to 2015 were retrospectively analyzed. The images were 3D-reconstructed with computer 3D CT angiography and arterial enhancement phase images were chosen for analysis. Linear distances from IMA root to abdominal aortic bifurcation and from LCA at IMA root level to IMA root were measured. Branch types of IMA, coursing pattern of LCA, and association between LCA and inferior mesenteric vein (IMV) site were summarized.

RESULTSOf 123 cases, 80 were males and 43 were females, mean age was (46.8±16.6) years, body weight was (57.7±10.4) kg, and BMI was (21.3±3.6) kg/m. The average distance from IMA root to abdominal aortic bifurcation was (42.5±7.9) mm, and this distance was closely associated with body weight (OR=4.771, 95%CI: 1.398 to 16.283, P=0.013). Longer distance tended to appear in the heavier patients. LCA and sigmoid artery (SA) originating from same single IMA was found in 61(49.6%) cases; LCA and SA forking at same point in 35(28.5%) cases; LCA and SA coursing together and forking afterwards in 24(19.5%) cases, and LCA disappearing in 3(2.4%) cases. In 71(57.7%) patients, LCA ascended medial to the lateral border of left kidney, while in 16(13.0%) patients, LCA arranged below the inferior border of left kidney. When the LCA site was higher and the distance from LCA to IMA root was closer [distance from LCA to IMA root level was (24.2±9.9) mm, (30.0±15.2) mm and (66.6±12.3) mm, F=83.2, P<0.001]. At the level of IMA root, LCA located medial to IMV in 21(17.1%) cases, located just lateral to IMV in 54(43.9%) cases, and located lateral and ascended far away from IMV in 48(39.0%) cases.

CONCLUSION3D-CT angiography is non-invasive, efficient and accurate in evaluating coursing features and variation of IMA and its branches, which can provide important reference to the surgeons, promising laparoscopic surgery smooth and safe.

Obesity is increasingly prevalent globally, searching for therapeutic agents acting on adipose tissue is of great importance. Equisetin (EQST), a meroterpenoid isolated from a marine sponge-derived fungus, has been reported to display antibacterial and antiviral activities. Here, we revealed that EQST displayed anti-obesity effects acting on adipose tissue through inhibiting adipogenesis in vitro and attenuating HFD-induced obesity in mice, doing so without affecting food intake, blood pressure or heart rate. We demonstrated that EQST inhibited the enzyme activity of 11β-hydroxysteroid dehydrogenase type 1 (11β-HSD1), a therapeutic target of obesity in adipose tissue. Anti-obesity properties of EQST were all offset by applying excessive 11β-HSD1's substrates and 11β-HSD1 inhibition through knockdown in vitro or 11β-HSD1 knockout in vivo. In the 11β-HSD1 bypass model constructed by adding excess 11β-HSD1 products, EQST's anti-obesity effects disappeared. Furthermore, EQST directly bond to 11β-HSD1 protein and presented remarkable better intensity on 11β-HSD1 inhibition and better efficacy on anti-obesity than known 11β-HSD1 inhibitor. Therefore, EQST can be developed into anti-obesity candidate compound, and this study may provide more clues for developing higher effective 11β-HSD1 inhibitors.
