An improved method for the determination of Vitamin D2 in baby food (fortified dried milk) was established by using two steps of high-performance liquid chromatography (HPLC). The sample was directly saponified and extracted with benzene. The extracted unsaponifiable matter was firstly subjected to preparative HPLC using a Nucleosil 5C18 column (reversed-phase type) with acetonitrile-methanol (3:2) as a mobile phase. This first step was for the purpose of clean-up, and a fraction containing Vitamin D2 was collected. The separate fraction was subsequently subjected to analytic HPLC with a Zorbax SIL column (straight-phase type) with isopropanol-hexane (0.8 : 99.2) as a mobile phase. The Vitamin D2 was separated from other contaminants and determined with ultraviolet spectrograph by the peak height estimated. The recovery rate was 84%, standard deviation 12.57 and coefficient of variation 4.57%. The proposed method was rapid, accurate, and suitable for the determination of baby food.

Liquid therapy is a vital method of perioperative treatment.Choosing correct kinds of transfusion and reasonable therapy strategies can significantly reduce the perioperative complications and shorten days in hospital and improve the critical patients prognosis.The historical development of perioperative liquid therapy is a forward process,which is about crystalloids vs.cilloid,dry vs.wet,and other controversial problems continuing to be summarized,explored and discussed.In this process,there are some specific perioperative treatment strategies with the physician having a deeper cognitive,such as goal-directed therapy,early goal directed therapy and fast track surgery which have significant clinical curative effect.This article summarizes the advance of perioperative liquid therapy.

This article reviewed the application of different kinds of imaging methods combined with the analysis of brain connectome in mild cognitive impairment. Previous studies demonstrated that the brain worked as the small-world network. In patients with Alzheimer's disease or mild cognitive impairment, the structure of small-world of network might be changed. According to the different methods, the trend of those changes might be different. This paper reviewed the current situation of the study in mild cognitive impairment through brain network analysis, and emphasized its importance and prospects.

Objective To detect serum levels of 25 ? hydroxyvitamin D (25 [OH] D) and matrix metalloproteinase 9(MMP?9)in patients with chronic spontaneous urticaria(CSU), and to explore their significance. Methods Totally, 56 patients with CSU and 25 healthy controls were enrolled into this study. High?performance liquid chromatography tandem?mass spectrometry(LC?MS/MS)and enzyme?linked immunosorbent assay(ELISA) were performed to measure serum levels of 25(OH)D and MMP?9 respectively in these subjects. Statistical analysis was carried out by two independent samples t?test or Wilcoxon rank sum test for comparisons of the above indexes between the two groups, and by Spearman rank correlation analysis for assessment of relationships between the serum levels of 25(OH)D and MMP?9 as well as between the two indexes and disease severity. Results Of the 56 patients, 19 were diagnosed with mild CSU, 26 with moderate CSU and 11 with severe CSU. Compared with the control group, the patient group showed significantly lower serum levels of 25(OH)D(21.74 ± 6.04 vs. 30.17 ± 2.21μg/L, P<0.05), but significantly higher serum levels of MMP?9(Median[P25-P75]:291.55[166.18-594.46]vs. 138.46[94.27-233.12]μg/L, P<0.05). In the patient group, the serum level of 25(OH)D was negatively correlated with that of MMP?9 (rs=-0.26, P<0.05), but uncorrelated with the severity of CSU(rs=-0.20, P>0.05);the serum level of MMP?9 was positively correlated with the severity of CSU(rs=0.27, P<0.05). Conclusion Vitamin D and MMP?9 may play a role in the occurrence of CSU.

Objective To investigate the clinical characteristics,treatment options and prognosis of duplex kidneys in children.Methods Data were retrospectively collected from all patients who were hospitalized at Shengjing Hospital Affiliated to China Medical University from January 2008 to May 201 5.The surgery to retain moie-ty nephron was performed in 30 cases:1 2 cases underwent non common sheath ureter reimplantation,4 cases of the patients had common sheath ureter reimplantation,1 2 patients underwent transurethral resection of the cyst,1 case of them had pyeloureterostomy,and the other patients underwent lower -pole pyeloplasty.Removal of renal moiety was performed in 52 cases:43 patients underwent upper -pole heminephrectomy,8 patients underwent upper pole hemi-nephrectomy and lower -pole ureter reimplantation,and 1 case of the patients had upper -pole heminephrectomy and lower -pole ureteroplasty.Results A total of 54 cases were followed up,the follow -up rate reached 65.9%,the follow -up time lasting 2 months to 4 years,with an average time of 9.53 months.All clinical symptoms disappeared after remove moiety operation.There were small ureteral cysts but compared with the preoperative condition,the symp-toms reduced significantly in 4 cases.All clinical symptoms disappeared in patients whose nephron was retained after operation,and hydronephrosis was alleviated.De novo 2 degree of vesicoureteral reflux was found in 3 out of 1 2 pa-tients who underwent transurethral puncture of the cyst.Conclusions The clinical manifestations of duplex kidney have some characteristics which include recurrent urinary tract infection,normal intermittent voiding urine dripping, abdominal pain,urethral orifice mass,abdominal mass and aggravation of hydronephrosis.Duplex kidney is often asso-ciated with cardiac malformation and cryptorchidism.The preoperative testicular examination and echocardiography should be performed.The choice of operation depends on the clinical manifestation,auxiliary examination results and comprehensive analysis.The prognosis of duplex kidney is well,but patients need to be further followed up af-ter operation.

Vaccination in children suffering neurological diseases is a troublesome issue that people es-pecially pediatricians are reluctant to mention. Due to worrying about the emergence of adverse reactions and concerning on the heat induced seizure,doctors and parents tend to cancel or do not recommend these children to be vaccinated. Additionally,the heat sensitive seizures,such as febrile seizure( FS) ,generalized epilepsy with fe-brile seizure plus(GEFS+),Dravet syndrome account for the largest proportion of the seizure related disease and epilepsy syndrome. Their pathogenesis has been proved relating to the mutation of SCN gene of the sodium channel. For children with FS,GEFS+,and Dravet syndrome,vaccination may lead to fever,which even may bring about convulsions,but it will not result in worse prognosis.

Objective To investigate the influence factors of cognitive impairment in epilepsy children with less than 6 years old. Methods Eighty-nine epilepsy children with less than 6 years old were selected. The neuropsychological detection was tested by Gesell developmental diagnostic scale (GDDS), and head imaging examination (CT or MRI) and ambulatory electroencephalogram (EGG) were checked. Results The scores of adaptive behavior, big sports behavior, fine motor behavior, language behavior and personal- social behavior were (82.98 ± 14.02), (85.86 ± 13.79), (83.14 ± 13.44), (84.75 ± 3.29) and (84.99 ± 14.37) scores, the average development quotient of the children with epilepsy were greater than 75 scores, and there were no statistical differences among them (P > 0.05). According to the test results of adaptive behavior, big sports behavior, fine motor behavior, language behavior and personal-social behavior, the rates of developmental delay children were 21.35% (19/89), 19.10% (17/89), 16.85% (15/89), 24.72% (22/89) and 22.47% (20/89), and the rates of moderate to severe developmental delay were 3.37% (3/89), 3.37% (3/89), 4.49% (4/89), 3.37% (3/89) and 3.37%(3/89). Multivariate analysis results showed that first onset age of epilepsy and head imaging performance were correlated with adaptive behavior, big sports behavior, fine motor behavior and personal-social behavior (P < 0.05). Conclusions The first onset age of epilepsy and head imaging performances are the major factors in cognitive performance in epilepsy children with less than 6 years old, so clinical attention should be paid to improve the prognosis of cognitive outcome of epilepsy children, and improve their life quality.
