Objective To understand the level of neonatal pain knowledge and attitudes of neonatal and obstetric department nurses, in order to supply the clinical basis for neonatal pain management. Methods Self-designed questionnaires to fill out on-site were distributed to 107 neonatal and obstetric department nurses (of which 40 were from neonatal department, 67 from obstetric department) for neonatal pain knowledge and attitudes. Results About question of neonatal pain, the average percentage of correct answers in the neonatal group was 75.5%, higher than 66.3% of the obstetric group, in the neonatal group, correct rate of seven questions was more than 80%,while in the obstetric group the correct rate of only one question was more than 80%, and 5 questions correct response rate was significantly lower than that of the neonatal group, the difference was significant. All nursing staff considered it essential or necessary to carry out the nursing knowledge of pain-related training. 95.0%(38/40) of neonatal nurses believed that they could properly assess the extent of neonatal pain, but only 83.6% (56/67) for the obstetric group, the difference between the two groups was significant. 97.5% (39/40) of neonatal nurses believed that they could make the right judgments on neonatal crying, and only 85.1%( 57/67) in the obstetric nurses, the difference between the two groups was significant.Conclusions Neonatal pain has gradually been recognized and paid attention to by the clinical front-line medical staff, they believe that it is necessary to receive training on neonatal pain, knowledge of neonatal pain of neonatal nurses is better than obstetric nurses.

Objective To determine the relative and independent risk factors of survival in patients with non-hepatitis B and non-hepatitis C hepatocellular carcinoma (NBNC-HCC).Methods The clinical records of 109 patients who underwent surgical resection for NBNC-HCC at Tianjin Medical University Cancer Institute & Hospital between January 2010 and January 2013 were retrospectively analyzed.The risk factors influencing disease-free survival (DFS) and overall survival (OS) were used as primary outcome measures.Univariate analysis was conducted to determine the relative risk factor predicting prognosis of NBNC-HCC,and the Cox proportional hazards model was used to determine independent risk factors of DFS and OS.Results For the 109 NBNC-HCC patients,the 1-,2-,3-year overall survival rates were 90.8％,78.0％ and 65.1％,respectively.The compounding disease-free survival rates were 74.0％,63.3％ and 55.8％,respectively.Univariate analysis showed the AFP level,ascites,and TNM staging were the risk factors of OS (all P ＜ O.05).The AFP level,ascites,BCLC stage,TNM staging were related with DFS (all P ＜ 0.05).Multivariate analysis demonstrated AFP and ascites to be the independent risk factors of OS and DFS.Conclusions AFP and ascites were independent risk factors of OS and DFS.For the NBNC-HCC patients,a strong positive AFP with ascites indicated poor prognosis.

ObjectiveTo analyze the association of human urate transporter 1 ( hURAT1 ) gene promoter single-nucleotide polymorphisms(SNPs) with primary hyperuricemia ( HUA ) in Chinese Han people.MethodsA total of 215 patients with HUA and 323 healthy subjects were chosen to be investigated of SNP of hURAT1 promoter by PCR and sequencing.ResultsFive SNPs were identified,including-454A/T,-434T/C,-382C/T,-87C/T,and + 118G/A.Pairwise linkage disequilibrium analysis displayed a high linkage disequilibrium between the five SNPs ( r2 =0.99).In HUA group,the heterozygous genotypos ( AT,CT,CT,CT,AG ) frequencies were significantly lower than those in control group ( P＜0.05 ).Logistic regression analysis showed that the heterozygosis genotypes ( AT,CT,CT,CT,AG) were protective factors of HUA ( OR 0.68-0.75 ).The minor allele ( T,C,T,T,A ) frequencies for both SNPs were significantly different between two groups ( P =0.022,P =0.038 ).ConclusionThese findings indicate that -454A/T,-434T/C,-382C/T,-87C/T,and + 118G/A SNPs of hURAT1 gene promoter area are associated with HUA in Chinese Han population.

ObjectiveTo detect the expressions of orotate phosphoribosyl transferase (OPRT) and dihydropyrimidine dchydrogenase (DPD) mRNA in gastric cancer tissues,and investigate their relationship with the clinicopathological factors.MethodsThe gastric cancer tissues and adjacent normal tissues were collected from 53 patients with gastric cancer at the Affiliated Hospital of Inner Mongolia Medical College from June 2007 to November 2008.The mRNA expressions of OPRT and DPD were detected by reverse transcriptional-polymerase chain reaction,and the correlation between the mRNA expressions of OPRT and DPD and the clinicopathological factors was analyzed.All data were analyzed by using the t test and the one-way analysis of variance.Results The mRNA expression of OPRT in the gastric cancer tissue was 1.15 ± 0.56,which was significantly higher than 0.88 ± 0.31 in the adjacent normal tissues ( t =3.66,P ＜ 0.05 ).The mRNA expressions of DPD in gastric cancer tissues and the adjacent normal tissues were 0.95 ± 0.50 and 0.90 ± 0.41,respectively,with no significant difference between the 2 groups (t =0.68,P ＞ 0.05 ).The mRNA cxprcssions of OPRT in the gastric cancer tissues with no lymph node metastasis was 1.42 ± 0.54,which was significantly higher than 1.00 ± 0.52 in the gastric cancer tissues with lymph node metastasis (t =7.94,P ＜ 0.05 ).Poorly differentiated adenocarcinoma (0.93 ± 0.24) and mucinous adenocarcinoma (1.58 ± 0.38) showed a significantly higher DPD mRNA expression than moderately differentiated or well differentiated adenocarcinoma ( 0.67 ± 0.36 ) ( F =27.71,P ＜ 0.05 ).Conclusions The mRNA expre ssion of OPRT in gastric cancer tissue is higher than that in the adjacent normal tissues,and its expression in patients with lvmph node metastasis is lower than that in patients without lymph node metastasis.Poorly differentiated adenocarcinoma showed higher DPD mRNA expression than moderately or well differentiated adenocarcinoma,and its expression is highest in mucinous adenocarcinoma.

A possible association between the polymorphism of glucose transporter 9 (GLUT9) rs1 3137343 and hyperuricemia was investigated in Chinese male population and the calculated genotype frequencies and allelic frequencies by PCR method and direct sequencing were reported.Data showed that there was statistical difference in GLUT9 rs13137343 genotype frequencies between hyperuricemia cases and controls(x2 =7.024,P =0.030).

Objective To investigate the effects of high-fat diet on fatty acid metabolism in liver and insulin sensitivity in aged rats and to explore the mechanisms of insulin resistance associated with aging. Methods Male Wistar rats aged 22-24 months were randomly divided into old control (OC) group and high-fat diet (HF) group. Male Wistar rats aged 4-5 months were selected as young control (YC) group. The rats in OC and YC were fed with basic diet, and the rats in HF group received high fat diet. Insulin sensitivity was evaluated by hyperinsulinemic-euglycemic clamp technique. Extracted liver triglyceride was measured by an automated biochemistry analyzer. Results (1) Compared with YC group, fasting blood glucose(FBG), fasting insulin(FINS) and free fatty acid were increased in OC group and were increased significantly in HF group. Triglyceride(TG) and total cholesterol(TC) levels were also elevated in HF group. (2) Compared with YC group, glucose infusion rate (GIR) was reduced in OC group and was decreased significantly in HF group. GIR was lower at the end of the 8th week than that at the end of the 4th week in HF group. (3) Compared with YC group, liver triglyceride was increased in OC group and was increased significantly in HF group. Liver triglyceride was negatively correlated with GIR, and positively correlated with FBG. Conclusions Compared with young rats, abnormal fatty acid metabolism and insulin resistance always exist in aged rats. High-fat feeding results in a significant increase in lipid content in liver and more serious insulin resistance in aged rats. Lipid accumulation in liver may contribute to insulin resistance associated with aging and high-fat diet.

Objective This study was to investigate the value of CT guided 125iodine implantation combining transcatheter arterial chemoembolization(TACE) to prevent digestive tract bleeding in patients with portal vein tumor thrombus in primary hepatocellular carcinoma. Methods Forty patients with portal vein tumor thrombus which were diagnosed to have primary hepatocellular carcinomas by diagnostic criteria of Chinese Anti-Cancer Association were collected prospectively. They were divided into the treatment group and the control group, with 20 patients in each group. The treatment group was treated by TACE for hepatic tumor and 125iodine seed implantation for portal vein tumor thrombus, while the control group was treated by TACE for hepatic tumor and only given β-blockers medicines after treatment. Intraoperative and postoperative surgery-related complications were observed. Three months after surgery, enhanced abdominal CT scanning was performed to evaluate treatment effects which were divided into complete response (CR), partial response (PR), and progressive disease (PD) and stable of disease (SD), and the local tumor control rates were calculated. The bleeding rates and mortality after 3 months, 6 months, 12 months were recorded. Treatment effects of the two groups were compared with continuously correction Chi-square test, bleeding rates were compared with Fisher test, and survival rates were analyzed with Kaplan-Meier survival curve and compared with Log-rank test. Results Overall the 40 patients were treated successfully without serious surgery-related complications. In the treatment group, there were 8 patients with PR, 6 with SD and 6 with PD, and the local control rates were 40% (8/20). In the control group, there were 1 patient with PR, 6 patients with SD and 13 with PD. The difference of the local control rates was statistically significant (χ2=5.161, P=0.023).The bleeding rates at 3, 6 and 12 months were 2, 2 and 3 cases in the treatment group, for control group they were 2, 6 and 10 cases respectively. There was no statistical difference between the 3 months and 6 months bleeding rates (P values were 1.000 and 0.235), but for 12 months bleeding rates, the difference was statistically significant (P=0.041).The 1 year cumulative survival rates of the treatment group and control group were 70% (14/20) and 40% (8/20), and the difference was statistically significant (χ2=4.675, P=0.031). Conclusion The treatment of 125iodine implantation combining transcatheter arterial chemoembolization in patients with portal vein tumor thrombus in primary hepatocellular carcinoma can reduce variceal bleeding rate and improve survival rate.

OBJECTIVETo investigate brazilein's role in energy metabolism of cerebral ischemia-reperfusion in mice.

METHODFourty mice were randomly divided into the sham group, ischemia group, brazilein 5 mg x kg(-1) group and brazilein 10 mg x kg(-1) group, each with ten cases. Cerebral ischemia model was the built. Mice were injected with brazilein three days before the operation, then they were killed. Cerebrum homogenate was prepared for the detecting of ATP, ADP, AMP and lactic acid by HPLC, expressions of MCT1 and MCT2 in mRNA level by RT-PCR.

RESULTThe lactic acid in cerebrum increased sharply 20 minutes after cerebral ischemia and decreased 1 hour after reperfusion, then returned to the normal level 24 hours after reperfusion. The charge of energy decreased significantly at the beginning of the ischemia-reperfusion, and the charge restored 1 hour after reperfusion though it was still much lower than the normal level at the time point of 24 hours. Moreover, MCT1 and MCT2 upregulated accompanied with the increase of lactate, MCT2 mRNA enhanced in brazilein 5 mg x kg(-1) group (P < 0.05) while both the two factors increased in brazilein 10 mg x kg(-1) group (P < 0.01).

CONCLUSIONBrazilein might protect neurons by changing the charge of energy.
