Objective To sdudy the expression of p53 and nm23-H1 proteins and their clinical significance in nasopharyngeal carcinoma.Methods The expression of p53 and nm23-H1 proteins were detected by immunohistochemistry method in 40 cases with nasopharyngeal carcinoma and 22 cases with chronic inflammation of nasopharyngeal mucosa tissues.Results Positive rates of p53 and nm23-H1 in chronic nasopharyngitis group were 1.0 ％,27.2 ％,and in the NPC group were 92.5 ％,55.0 ％.There were 9 cases with the positive expression of p53 in 22 cases of nasopharyngeal carcinoma tissues with the positive expression of nm23-H1 (40.9 ％).There were 17 cases with the positive expression of p53 in 18 cases with the negative expression of nm23-H1 (94.4 ％).The expression of p53 and nm23-H1 proteins in nasopharyngeal carcinoma were much higher than that in chronic inflammation of nasopharyngeal mucosa tissues.The expression of p53 protein in nasopharyngeal carcinoma with metastatic lymph node was higher than that in nasopharyngeal carcinoma without metastatic lymph node,but nm23-H1 protein lower.The expression of p53 protein was positively correlated with the metastasis,clinnical staging and pathological classification but not correlated with T classification of nasopharyngeal carcinoma.The expression of nm23-H1 protein was negative correlation with the metastasis and clinical staging of nasopharyngeal carcinoma.Conclusion p53 and nm23-H1 play important coordinated regulation roles in the carcinogenesis,development and metastasis of nasopharyngeal carcinoma and will probably become the key biological marks in the judging and evaluating prognosis of nasopharyngeal carcinoma.

Objective To evaluate the clinical value of small doses of solifenacin to treat children of primary nocturnal enuresis. Methods Children (n=78) of primary nocturnal enuresis were randomly divided into treatment group(39 cases) and control group(39 cases). All children received behavioral intervention therapy, while children in the treatment group were given Solifenacin(5 mg/tablet, 1/3 tablet, 1 times a day for 3 months) orally besides behavioral therapy. Children were followed up for 3 months after the end of the treatment, and the curative effect and recurrence rate were compared between two groups. Results Compared with that of children in control group, cure rate of children in treatment group is higher at the end of treatment (89.7%vs 69.2%, P<0.05) as well as by 3 month of follow-up time (82.1%vs 46.2%, P<0.05). The re?currence rate of children in treatment group, by three months follow-up time, was lower than that of children in control group (8.6%vs 33.3%,P<0.05). Conclusion Small dose of Solifenacin in addition to behavioral intervention is safe and effec?tive in treatment of children with enuresis, which enhance cure rate and reduce recurrence.

Objective To determine the effects of Hyperoside ( Hyp) on the memory impairment induced by hypobaric hypoxia. Meth-ods SD rats were exposed in hypobaric hypoxia chamber which simulated 6 100 m high altitude for 7 days to induce memory impairment. Morris maze was applied to determine the effects of Hyp on memory in hypobaric chamber. The activities of SOD and CAT and levels of GSH and MDA in rat hippocampus were measured by assay kit ( Nanjing Jiancheng Bioengineering Institute) . Results In target quadrant,the time and path and the frequency to cross platform were reduced under hypobaric hypoxia as compared with normoxia group ( P < 0. 05 or P<0. 01). Administration of Hyp significantly attenuated the hypoxia-induced the memory impairment responses(P<0. 05 or P<0. 01). The activities of SOD and CAT in rats hippocampus exposed to hypobaric hypoxia were significantly improved in the presence of Hyp as com-pared with the absence of Hyp(P<0. 05 or P<0. 01),so did GSH level (P<0. 05 or P<0. 01). Significant decrease of MDA levels was observed in the hippocampus on exposure to hypobaric hypoxia with Hyp as compared without Hyp. Conclusion Hyp reduces hypoxia-in-duced oxidative stress injury by upregulating activity of antioxidant proteins such as SOD,CAT in hippocampus of rats, which contribute to at-tenuate memory impairment induced by hypobaric hypoxia.

Objective To develop a method for the determination of trace mercury in waste water by atomic fluorescence spectrometry. Methods The mercury vapor was generated with the hydride generation agent potassium tetrahydroborate (KBH4) in hydrochloric acid. The optimum working conditions of the instrument were studied, including flow rate of carrier gas, concentration of potassium tetrahydroborate solution and acidity of sample solution. Results Under the optimum condition, the linear range of determination was 0-20 ng/ml, the detection limit was 0.04 ng/ml, the relative standard deviation was 1.9% (n=11) for 5 ng/ml Hg, the recovery rate was in the range of 96%-104%. Conclusion This method is applicable to the determination of mercury in the waste water.

Objective To investigat the safe time of SVC interruption in New Zealand rabbits, and help to find the safe time ofSVC interruption in chnical operation. Methods 25 New-Zealand rabbits were separated into 3 groups randomly. Bi-SVC was cross-clamped for one hour, two hours in animal models. The femoral artery or SVC pressures were monitored. The control group (sham op-eration group, 5) were opened chest both sides and monitored femoral artery pressure and SVC pressure for 2 hours. Samples of cere-brum, cerebellum and medulla of rabbits immediately post-operation were studied for water content, light and electric microscopies.The tiny change of brain cells in brain mantle, hippocampus and thalamencephal were observed under electron microscope. Results(1) The SVC pressure of rabbits varied regularly in occlusion groups, which displayed as "upgrade-degression- upgrade again-retain".(2) There was no obvious difference in water content of brain between the one hour group and the control group, both of which weremuch lower than two hours group. (3) The brain tissues were almost in normal construction in one hour group, but encephaledema wasobserved in two hours group. The pathological change of cony brain cells was light and reversible in one hour group. However, in twohours group, necrosis of neuron ceils in brain could be observed, which was irreversible. Concerto The animal model of acuteSVC obstruction was built successfully. Interruption of the SVC for 1 hour was proved safe, with longer interruption of SVC 2 hours,obvious encephaledema and necrosis of neuron cells can be observed.

Objective To study the effect of high frequency stimulation (HFS) in pedunculopontine nucleus (PPN) on the neuronal activities of globus pallidus internus (Gpi) in Parkinson’s disease (PD) model rats, and the mechanisms there-of. Methods Seventy male Sprague-Dawley rats were divided into two groups, control group (n=30) and PD model group (n=40). PD rat model was established by the injection of 6-OHDA into substantia nigra pars compacta (SNc) on the right side of the brain with stereotactic technique. Electrophysiological recordings were made in anaesthetized rats to investigate the ef-fects of HFS-PPN on the firing rate of the GPi neurons. Brain microdialysis combined with high-performance liquid chroma-tography was applied to detect glutamate (Glu) andγ-aminobutyric acid (GABA) levels in GPi. Results HFS-PPN caused an excitatory reaction of the majority of neurons recorded in the GPi in PD model group and control group. The mean firing rate of GPi excited neurons was significantly increased (P﹤0.01). The levels of Glu were reduced under HFS-PPN and the levels of GABA were not affected (P>0.05).Conclusion HFS-PPN heightened the electrical activity of GPi neurons and re-duced the level of Glu. These excitatory effects were probably realized by PPN-GPi direct path or other indirect path.

Objective To investigate the effect of plasma homocysteine (Hcy) levels and cognitive dysfunction on patients with type 2 diabetes and explore the other factors that affect cognitive function.Methods 80 patients with type 2 diabetes were selected as our subjects and they were divided into cognitive impairment group (38 cases),cognitive normal group (42 cases) according to a simple mental state scale(MMSE) score.The plasma Hcy,glycosylated hemoglobin,blood lipid,uric acid,24 h urine trace albumin were measured.Results Plasma Hcy concentration in diabetic cognitive dysfunction,non cognitive impairment group and normal control group respectively were(19.56 ± 5.23),(16.21 ± 3.27),(14.67 ± 4.27) tmol/L,and there was statistically significant difference(F =3.76,P ＜0.05).The plasma Hcy levels in diabetic cognitive impairment group was higher than that non-cognitive impairment group(P ＜ 0.05) and normal control group (P ＜ 0.01),The factors impaired cognitive function in patients with other factors included age,glycosylated hemoglobin,body mass index,diabetes duration and plasma Hcy levels,and there were negative correlation with MMSE score (r =-0.336,-0.285,-0.226,-0.392,-0.312 ; all P values were less than 0.05).Conclusion Patient's age,duration of diabetes,glycosylated hemoglobin and BMI can affect cognitive function in patients.Higher Hcy levels in patients with type 2 diabetes is a risk factor for cognitive impairment.

Objective To evaluate the effect of the empowerment theory-based health education on anxiety, depression and self-efficacy in the major caregivers for patient with leukemia. Methods Eighty patients with leukemia and their caregivers were enrolled during November 2013 to November 2014 and were divided into the intervention group (n=40) and the control group (n=40). The caregivers of the intervention group received empowerment theory-based education , while those of the control group received general health education. The two groups were compared in terms of anxiety, depression and self-efficacy. Results Before intervention, there were no significant differences in the three items between the groups (P>0.05). After intervention, the level of self efficacy in the intervention group was better than that in the control group (P<0.05) and the scores in the intervention group were significantly lower than those of the control group. Conclusion The empowerment theory-based education can relieve anxiety and depression and improve the self efficacy of the caregivers of patients with leukemia.
