Abstract Diabetic ketoacidosis (DKA) is a serious complication of diabetes in children. A small number of children with DKA can be complicated by cerebral edema, leading to acute brain dysfunction, which is the main cause of death in children with diabetes. Because of unclear pathogenesis and non-specific clinical manifestations, DKA complicated with brain edema is easy to be missed or misdiagnosed. The identification and management of risk factors of DKA complicated with brain edema and early identification of brain edema are of great importance for improving the prognosis. This article reviewed the literature about the pathogenesis, clinical manifestations, risk factors, treatment and prevention of DKA complicated with brain edema, so as to provide reference for its early clinical identification and intervention.

Objective To explore the clinical effect of two different connecting tubes in hemodialysis combined with hemoperfusion. Methods A total of 25 patients were selected and divided into observation group and control group by self- control method. In the observation group, the hemodialysis combined with hemoperfusion was used 8 times, and the control group was treated with hemodialysis combined with hemoperfusion 8 times using conventional connecting tube. The time of the unloading of the perfusate and the amount of physiological saline required were compared between the two groups. There was no blood spillover during the unloading of the perfusate, the number of cases of allergic reaction during the treatment, and the coagulation of the dialyzer and the pipeline after the treatment. Results There was no allergic reaction in both groups. There was no significant difference between the two groups in the amount of saline needed to return blood (t=46.412, P=0.307). In the control group, there was 15 cases of blood spillover, while the observation group did not show blood spillover. There was significant difference between the two groups in unloading perfusion time(4.43±0.14)min vs. (3.02±0.11) min (t=10.784, P=0.003). The level Ⅰ and Ⅱ blood coagulation of dialyzer and pipeline was 12, 2 cases in the control group after the treatment and 5, 0 case in the observation group, no level Ⅲ blood coagulation cases, and there was a significant difference between the two groups (χ2=10.667, P<0.01). Conclusion In the hemodialysis combined with hemoperfusion therapy, multi-function group of the application effect is superior to conventional piping, is worthy of clinical application.

BACKGROUND: Embryonic stem cells (ESCs), the seed cells of all mature cells in vivo, are useful tools for nerve transplantation and developmental gene function research. Notch1 signaling pathway is the key pathway to control the ordered neural development and differentiation of many kinds of neural cells, however, there is no report on the dynamic expression of Notch1 signal during the ESC differentiation to date. OBJECTIVE: To investigate the expression of Notch1 protein, transmembrane signal transduction molecule, during directional differentiation of embryonic stem cells into neural cells. DESIGN, TIME AND SETTING: Cell research was carried out between October 2003 and October 2004 at Zhongshan Ophthalmic Center, SUN Yat-sen University, Guangzhou, Guangdong Province, China. MATERIALS: BALB/C mouse embryonic stem cell line Ⅵ (passage 11)was obtained from experimental animal center of SUN Yat-sen University, provided by professor Huang Bing. ESC culture medium was high-glucose DMEM medium with 20% bovine serum and 106 IU/L mouse leukemia inhibitory factor. Induced differentiation medium was high-glucose DMEM medium with 20% fetal bovine.serum and 5×107 mol/L retinoid acid(RA). METHODS: Passage 11 ESCs were resuscitated and incubated by ESC culture medium in incubator at 37℃ with 5% CO2. Passage 11 ESCs were subcultured after 2 or 3 days and RA was added into medium to induce differentiation. Three time points for observation were established: induced for 1, 5 and 9 days. MAIN OUTCOME MEASURES: Morphological changes were observed under inverted phase contrast microscope, MAP-2 antigen expressed in differentiated cells was detected by immunofluorescence method. Immunocytochemistry, Western Blot, flow cytometry assay were used to investigate the Notch1 protein expression. RESULTS: ESCs presented clone-like growth. After induced by RA for 9 days, single neural network was achieved around most of the cell clusters. With the prolongation of induction, MAP-2 positive neural cells increased gradually. Almost all ESC clones expressed Notch1 protein strongly or positively, but Notehl protein expression decreased gradually after induced differentiation (P < 0.01). CONCLUSION: Notch1 signal shuts off progressively during induction of ESCs into neural cells, which suggests Notch1 may play an important role in the differentiation of ESCs into neural cells.

OBJECTIVE:To discuss the general regularity and characteristics of the drug-induced edema so as to provide reference for clinical safe medication.METHODS:173 drug-induced edema cases publicly reported in domestic journal from 2001 to 2006 were analyzed statistically.RESULTS:The drug-induced edema was more often seen in males than in females,but not linked to age.It was characterized by early onset,with 76(43.9%)showing edema within 1h.It was chiefly induced vial oral and intravenous routes.The drug-induced edema was caused by 17 drug categories(or 115 kinds),with antibacterials showing the highest percentage(31.2%,54 cases).Laryngeal edema,which occurred in 57 cases,was the chief type among all the edema cases.CONCLUSION:Drug-induced edema is a common adverse drug reaction,which should be given great attention in the clinic,much as in the case of acute laryngeal edema.Clinicians should give close monitoring on patients after medication to guard against possible events.

Objective:To investigate YKL-40-mediated inflammation in human bronchial epithelial cells and analyzed the soluble factors secreted by bronchial epithelial cells exposed to YKL-40 that were responsible for increasing proliferation and migration of primary normal human bronchial smooth muscle cells (BSMCs).Methods:YKL-40-induced inflammation was assayed in two human bronchial epithelial cells (BEAS-2B cell line and primary human bronchial epithelial cells ,namely HBECs).In addition,we treated BEAS-2B cells and HBECs with YKL-40,and added the conditioned culture media ( YKL-40-BEAS-2B-CM) and ( YKL-40-HBECs-CM) to BSMCs.The proliferation and migration of BSMCs were determined by premixed WST-1 cell proliferation reagent and QCM chemotaxis migration assay ,respectively.Results: Bronchial epithelial cells treated with YKL-40 resulted in a significant increase of IL-8 production,but have no effect about RANTES ,Eotaxin and TNF-α.YKL-40-BEAS-2B-CM and YKL-40-HBECs-CM induced IL-8 was found to further stimulate proliferation and migration of BSMCs ,and the effects were inhibited after neutralizing IL-8.Conclusion:Through investigating the interaction of airway epithelium and smooth muscle ,our findings implicate that YKL-40 may be involved in the inflammation of asthma by induction of IL-8 from epithelium,subsequently contributing to BSMCs proliferation and migration.Moreover, inhibition of IL-8 signaling is a potential therapeutic target for YKL-40-induced inflammation and remodeling of asthma.

In this study, sonography video urodynamic studies (SVUDS), which combined synchronically urodynamic studies with trans-perineal and trans-abdominal sonography, were used to detect female bladder outlet obstruction (FBOO). The dynamic changes of urethra and surrounding pelvic floor structure during storage and voiding phase were observed by SVUDS and the causes of FBOO were analyzed. And the findings were as follows: 13 patients showed organ prolapse, there was an urethral angulation deformity during urination; 5 cases had abnormal urination as the urethral opening was not good in the middle of urination period; 4 cases had urethral stricture, as the proximal end of the obstruction dilated during urination, and the obstruction site showed no relaxation; 1 case had primary bladder neck obstruction with an incomplete opening of the bladder neck during urination; 3 cases had idiopathic bladder outlet obstruction and the sphincter of bladder neck and urethra opened well during urination.
