Chromosome 22qll deletion syndrome(22q11DS) is a common chromosomal microdeletion syndrome. Its clinical manifestation is complex, comprising congenital heart disease, dysmorphic facial, immunodeficiency, endocrine dysfunction and so on. The syndrome has a population prevalence of approximately 1/2500-1/4000. There have been many recent advances in understanding of the clinical manifestation, behavior and psychiatric problems and the mechanisms leading to the specific phenotypic features in chromosome 22q11 deletion syndrome. Asymmetric recombination of homologous low copy repetitives in the deletion region causes the deletion of 22q11. TBX1 is the dominant gene contributing to the phenotype.

Objective To assess the clinical effectiveness and safety of gatifloxacin gel to bacterial conjunctivitis. Methods Double-blind and random selection were designed for the study,with levofloxacin gel as the control medicine.Thirty-six eyes of the experimental group and 36 of the control group were eligible for evaluation.Each eye received the gel one drop a time and three times per day.The gels were applied to the conjunctiva sac for 7 d. Results The clinic effectiveness of experimental group and control group were 88.89% and 91.67%,which indicated no significant difference.Microbial eradication rates were 90.48% and 93.75%,no significant difference either.Safety composite scores were similar between groups. Conclusion Gatifloxacin ophthalmic gel is safe and effective for treatment of bacterial conjunctivitis,and contains certain clinical value.

Separations of neurotransmitters such as dopamine (DA), ser otonin (5-HA), norepinephrine (NE) and epinephrine (E) were performed successf ully using a homemade electric field modulated capillary electrophoretic system, which could offer both radial and axial electric fields with only one high volt age power supply. DA and 5-HT were eluted simulaneously and could not be resolv ed in 0.01 mol/L phosphate buffer at pH 2.5. Alcohol additives, such as methanol , ethanol or 1-propanol were added to the buffer to change the solvation shell of the solutes, which changed their effective sizes and electrophoretic mobiliti es of the solutes accordingly. The optimum composition was a buffer of 20% (V ／V） 1-propanol, with resulted resolutions 0.74 (DA/5-HT), 0.56(5-HT/NE) and 0.77 (NE/E). If a positive radial voltage of 6.6 kV was applied, the resolut ions were improved to 1.48, 0.71 and 1.32, respectively.

This paper introduces the perioperative nursing of 20 cases of branchial cysts in newborn with cyst extraction. The nursing care focused on body position,respiratory care,diet management and wound care,which alleviated the patients' dyspnea,prevented respiratory aspiration and promoted wound healing. All the 20 newborn recovered well without recurrence in the four years after the operation.

Objective　To investigate the effect of placental isoferritin in pathogenesis of preeclampsia and its predictive value. Methods　A prospective double-blinded study was performed. There were 120 initial normal pregnant women at earlier third trimester (from 24 to 34 weeks) in this study. Their plasma placental isoferritin and nitric oxide (NO) metabolites (nitrite/nitrate) (NO2-/NO3-) were examined by enzyme linked immunoabsorbent assay (ELISA) and Griess assay respectively. The outcomes of pregnancies were followed up. Results　In 120 initial normal pregnant women, 19 pregnant women occurred preeclampsia (preeclampsia group), and 101 cases were normal (normal group) at follow up. The levels of plasma placental isoferritin (PLF) were significantly decreased in preeclampsia group (285.31±53.73 mg/L) than that of normal group (699.05±203.03) mg/L, P＜0.01. The levels of plasma NO were significantly increased in preeclampsia group (54.57±32.71 μmol/L) than that of normal group (38.89±30.00) μmol/L, P＜0.05. The significant negative correlation between the plasma placental isoferritin and NO levels was observed（r=0.329，P<0.01）. At the cut point of 400 mg/L PLF level, the sensitivity, specificity, positive predictive value, negative predictive value and Kappa index of PLF level predicting on the outcomes of pregnancy with preeclampsia were 100%, 85.15%, 55.88%, 100%, 0.645. Conclusions　 The decrease of plasma placental isoferritin levels is associated with preeclampsia, and the endothelial cell damage may be one of its mechanism. The PLF may be an earlier predictor of preeclampsia at 24～34 gestational weeks.

BACKGROUND:Daclizumab can be special y combined with the inerleukin-2 receptor on the surface of activated T cells in human body, and this method can reflect the close of interleukin-2 receptor thus inferring the effect of induction therapy. At present, the daclizumab has been widely used in renal transplantation, but there is no consensus on its clinical application in liver transplantation. OBJECTIVE:To investigate the expression of serum CD25+T cells and soluble interleukin-2 receptor in the patients receiving daclizumab for liver transplantation during perioperative period. METHODS:A total of 58 patients received orthotopic liver transplant for the first time were included and then the patients were randomly divided into two groups:control group (n=28) and treatment group (n=30). The patients in the two groups were treated with tacrolimus, mycophenolate mofetil and corticosteroids triple immunosuppressive regimen. The patients in the treatment group received immune induction therapy with daclizumab, and the patients in the control group did not receive daclizumab. RESULTS AND CONCLUSION:Flow cytometry and enzyme-linked immunosorbent assay showed the expression levels of CD25+T cells in the treatment group were significantly lower than those in the control group at different time points after liver transplantation (P<0.01);and the expression levels of soluble interleukin-2 receptor in the treatment group were lower than those in the control group during transplantation and at the first day after transplantation (P<0.05, P<0.01). At 6 months after transplantation, the incidence of acute rejection was decreased in the treatment group (P<0.01). The results indicate that daclizumab can effectively suppress the expression level of CD25+T cells, as wel as the expression level of soluble interleukin-2 receptor in the peripheral blood in the early stage of liver transplantation, thus effectively reducing the rate of acute rejection.

Objective To observe the effectiveness of transferring human A20 gene into endothelial cells. Methods The shuttle plasmid pCAGGSEHA20 was constructed using gene cloning and recombined technique. Endothelial cells were transfected with pCAGGSEHA20 and pMAMneo by DOTAP. The postive cell clones were selected with G418. The stable transfection and expression of A20 in the endothelial cells were determined by in situ hybridization and immunohistochemical analysis. Results The two fragments digested from pCAGGSEHA20 by EcoRⅠ represented 4 6?kb and 2 3?kb by electrophoresis, which were confirmed to be the carrier and the A20 gene fragments inserted originally. The above results indicate that the construction of pCAGGSEHA20 was successful. Abundant A20 stable expression in endothelial cells transfected with pCAGGSEHA20 was confirmed by in situ hybridization and immunohistochemical analysis.Conclusion By means of the DOTAP, hA20 gene can be transferred and stably expressed in endothelial cells.

Objective:To supply the rescue and treatment to stroke patients in the first time by the building of green information network platform. Methods:Build green information network platform, which taking the UCC as the entrance, using the IP green alarm bell system as the start point, mixing the Hospital Information System, Picture Archiving and Communication Systems, Laboratory Information System, and office automation system together. The platform attains the features of systems interflowed, equipment connected, information shared and data sending at once. These features make the sharing of patient’s information accurate and faster, so that the emergency rescue process is optimized. Results:In the past, it might cost about 20 minutes between the patients’ arriving and the rescue’s starting. When the green information network platform was used, the time was reduced to about 3 minutes. Conclusion: The green information network platform can optimize the process of emergency rescue effectively.
