Objective To evaluate the application effect of bedside evaluation of deglutition function and predictive nursing intervention on patients with dysphagia in neurology department. Methods 320 Patients with dysphagia were divided into the observation group and control group with 160 cases in each group. The observation group was given admission nursing evaluation and bedside evaluation of deglutition function while the control group only received admission nursing evaluation. The incidence of complications in each group were assessed. Results The incidence of complications such as aspiration, pulmonary infection, asphyxia and metabolic disturbance in the observation group was lower than that of the control group(P＜0.01).Conclusion The bedside evaluation of deglutition function could accurately evaluate the degree of swallowing disorder and supply theoretical evidence for predictive nursing intervention by in structing clinical application of selective measures for patients with dysphagia. This could guarantee safe food intake and reductive incidence of complications of patients. So we advocated that bedside evaluation of deglutition function should be a routine admission nursing evaluation in neurology department.

Objective To observe the clinical effects of Shenqi Fuzheng Injection in treatment of sepsis in children and its effect on the serum levels of high mobility group protein-1 and tumor necrosis factor-α, lactic acid, C reactive protein, procalcitonin levels.Methods 140 patients with sepsis were chosen, and randomly divided into two groups, the observation group and the control group.Two groups were given treatment by the national standard of sepsis, while the control group only received basic treatment, the observation group on the basis of conventional treatment combined with Shenqi Fuzheng injection.Two groups of clinical curative effect and the levels of serum HMG-1, TNF-α, LA, CRP, PCT level were observed.

Objective To investigate the causes, diagnosis and treatment of infants with secondary methylmalonic aciduria due to maternal vitamin B 12 deficiency. Methods The clinical, laboratory data and treatment of 7 children with secondary methylmalonic aciduria and their mothers′ health and nutrition were retrospectively reviewed. Results All children were presented to the hospital with vomiting, seizures or mental retardation during 1 to 13 months after birth. Varied degrees of anemia was found in 6 infants and 5 with metabolic acidosis and liver dysfunction. Methylmalonic aciduria was found in all subjects. Four of the mothers had chronic gastritis, one with gallstones in liver and gallbladder and one was a vegetarian. Decreased serum level of vitamin B 12 and folic acid and elevated homocystine concentrations were found in all mothers. After vitamin B 12 and folic acid supplementation, significant improvement was observed in all patients. Six infants showed normal development and one had mild mental retardation. Conclusions Chronic gastritis, liver/gall bladder diseases or being a vegetarian might lead to maternal vitamin B 12 deficiency and then infantile secondary methylmalonic aciduria. Early diagnosis and vitamin B 12 and folic acid supplement are crucial in improving the prognosis.

Hyoscyamine 6 beta-hydroxylase (H6H) is the last rate-limiting enzyme directly catalyzing the formation of scopolamine in tropane alkaloids (TAs) biosynthesis pathway. It is the primary target gene in the genetic modification of TAs metabolic pathway. Full-length cDNA and gDNA sequences of a novel H6H gene were cloned from Datura arborea (DaH6H, GenBank accession numbers for cDNA and gDNA are KR006981 and KR006983, respectively). Nucleotide sequence analysis reveals an open reading frame of 1375 bp encoding 347 amino acids in the cDNA of DaH6H, while the gDNA of DaH6H contains four exons and three introns, with the highest similarity to the gDNA of H6H from D. stramonium. DaH6H also exhibited the most identity of 90.5% with DsH6H in amino acids and harbored conserved 2-oxoglutarate binding motif and two iron binding motifs. The expression level of DaH6H was highest in the mature leaf, followed by the secondary root, and with no expression in the primary root based on qPCR analysis. Its expression was inhibited by MeJA. DaH6H was expressed in E. coli and a 39 kD recombinant protein was detected in SDS-PAGE. Comparison of the contents of scopolamine and hyoscyamine in various TAs-producing plants revealed that D. arborea was one of the rare scopolamine predominant plants. Cloning of DaH6H gene will allow more research in the molecular regulatory mechanism of TAs biosynthesis in distinct plants and provide a new candidate gene for scopolamine metabolic engineering.

Objective:To investigate the curative effect of hysterectomy and lymph node dissection with laparoscope or laparotomy on elderly patients with cervical cancer.Methods:60 elderly patients with cervical cancer were enrolled in our hospital from January 2014 to January 2016 and randomly divided into two groups.Group A (n=30) accepted hysterectomy and lymph node dissection with laparotomy,and Group B (n=30) adopted same surgery with laparoscope,the operation condition and postoperative recovery were compared between two groups.The intraoperative and postoperative complications of all patients were recorded and analyzed,and the quality of life of patients was evaluated in the following-up period.Results:The number of lymph node dissection in Group B was significantly more than that of Group A (P＜0.05);the intraoperitive blood loss and the times of using postoperative analgesia pump in Group B were significantly fewer than those in Group A (P＜0.05).The time of postoperative exhaust,bladder function recovery,drainage tube retention and hospital stay in Group B were all shorter than those in Group A(P＜0.05).The incidence of massive hemorrhage during operation and postoperative urinary retention and lymphatic cyst in Group B were significantly lower than those patients in Group A (P＜0.05).After operation 3 and 6 month,the I-QOL and FACT-G scores of patients in Group B were significantly higher than those in Group A (P＜0.05).Conclusions:Hysterectomy and lymph node dissection under laparoscope had remarkable curative effect on the elderly patients with cervical cancer,which improved the postoperative recovery and the quality of life of patients.

Objective To screen for proteins interacting with novel gene AngRem104 and to identify the putative interaction of novel gene AngRem104 and Bardet-Bied1 syndrome 2 (BBS2) protein in mammalian cells. Methods The yeast strain AH109 was transformed with AngRem104pGBKT7/c-myc and yeast-mating was utilized to screen for interacting proteins with AngRem104 in pretransformed human kidney cDNA library.

Mouse anti-human V5 monoclonal antibody and mouse anti-human c-myc monoclonal antibody were used in immunoprecipitation and immunoblot analysis, respectively. Results Seven proteins that interact with AngRem104, including BBS2 were identified. The AngRem104-V5 and the BBS2-c-myc fusion protein were detected respectively in the immunoprecipitation by anti-c-myc and anti-V5 antibody. Conclusion The novel gene AngRem104 may interact with BBS2 protein in mammalian cells,which provides insights as to the function exploration of novel gene AngRem104 and the pathogenesis investigation of Bardet-Biedl syndrome.

Objective To explore the relationship between the polymophisms of interleukin?17 (IL?17)?197A/G and the outcomes of hepatitis B virus (HBV) infections. Methods The polymorphism of genotypes and al?leles of IL?17?197A/G in 222 chronic HBV infected patients and 88 HBV infected ones as controls. The contains of serum HBV DNA were detected using PCR combined with DNA amplification in vitro, serum IL?17 expression was detected with ELISA and genotype and allele frequency of IL?17?197A/G locus was detected by Beckman SNP kit. Results There was a significant difference in the serum IL?17 expression (F=158.1, r2=0.61, P<0.000 1) among all the groups. For IL?17?197A/G, there were significant differences for the comparison between the two groups, and the frequency of AA genotype was 47.72%in liver cirrhosis group. Moreover, the highest frequency of GG was in HBV clear?ance group (74.81%);and the lowest group was in chronic HBV liver cirrohosis group (19.05%). Conclusion IL?17?197A/G AA genotype and allele might be associated with susceptibility of HBV infection in Han population in Hei?bei Province.

ObjectiveTo analyze the characteristics of neonatal hyperammonemia and citrullinemia caused by argininosuccinate lyase (ASL) gene mutations, and to have a better understanding of this disease. MethodsA neonatal patient with the onset of hyperammonemia and citrullinemia admitted to the Department of Pediatrics of Peking University First Hospital on April 2, 2014, was retrospectively studied. Peripheral blood leukocyte DNA of the patient and his parents was collected to detectASS1,ASL andSLC25A13 gene mutations. The literature related to neonatal hyperammonemia, citrullinemia and argininosuccinic aciduria was reviewed. ResultsThe baby in this case appeared lethargic, had weaker crying and food refusal since three days after birth, and analysis of blood amino acid found a marked increase in blood ammonia (1 332μmol/L) and a significant rise in citrulline (759.12μmol/L). Sanger sequencing detection revealed compound heterozygous mutations in theASL gene (c.434 A>G, c.857A>C) and this c.857A>C mutation was the first reported case in China. This case of hyperammonemia and citrullinemia was confirmed as argininosuccinic aciduria caused by ASL gene mutations. A protein-limited diet and the treatment of arginine and L-carnitine were given. His blood ammonia decreased to normal level and there was a significant improvement in physical and intellectual progress at five months old. Unfortunately, he had an intestinal infection when he was over five months old and the blood ammonia level tested in the local hospital was 480μmol/L. Gradually there was a disturbance of consciousness, then coma, and he finally died after active rescue in the local hospital.ConclusionsHyperammonemia and citrullinemia in neonates are likely to be argininosuccinic aciduria and a gene mutation test may be helpful for diagnosis.

Objective To investigate the role of Notch signaling pathway in cerebral ischemic tolenmce induced by clectroacupuncture (EA) preconditioning.Methods Fifty-two adult male SD rats weighing 280-320 g were randomly divided into 2 groups(n=each):control group(group C)and electroacupuncture preconditionig group(group EA).Group C received no treatment.Group EA received EA at the Baihui acupoint (GV20) for 30 min a day for 5 days.Twenty-four hours after the last preconditionig,focal cerebral ischemia was induced by middle cerebral artery occlusion (MCAO) for 120 min,followed by 72 h of reperfusion.Notch intracellular domain(NICD)expression was determined by Western blot and expression of Notch1,Notch4,Jag1,and Hes1 mRNA by real-time PCR immediately before iachemia and 24 and 72 h of reperfusion.The neurological deficit was scored at 72 h of reperfusion.The infarct volumes were then determined after evaluation of the neurological deficit score .Results There was no significant difference in Hesl mRNA and NICD expression immediately before ischemia between group EA and C(P>O.05).NICD expression was up-regulated at 24 and 72 h of reperfusion in both groups, and Hesl mRNA expression at 72 h of reperfusion in group C and at 24 h of reperfusion in group EA was up-regulated compared with those immediately before ischemia (P < 0.05). Hes1 mRNA and NICD expression was up-regulated in group C, while down-regulated in group EA at 72 h of reperfusion compared with those at 24 h of reperfusion ( P < 0.05 ). Compared with group C, the expression of Notchl,Notch4 and Jag1 mRNA was up-regulated immediately before ischemia, and Hes1 mRNA and NICD expression was up-regulated at 24 h of reperfusion while down-regulated at 72 h of reperfusion in group EA( P < 0.05). EA preconditioning significantly reduced infarct volumes and increased neurological deficit scores at 72 h of reperfusion (P < 0.05 ). Conclusion Notch signaling pathway may participate in cerebral ischemic tolerance induced by EA preconditioning.
