Objective:To study the expression of IQ motif containing GTPase activating protein 1 (IQGAP1 )in oral squamous cell cancer(OSCC)tissue,and to explore the effects of IQGAP1 on cell proliferation and invasion as well as its underlying mechanism. Methods:Expression levels of IQGAP1 in tumor and adjacent normal tissues were examined by western blot and RT-PCR.OSCC cell line SCC-4 cells was transfected with the recombinant plasmid-pcDNA3.1 -IQGAP1 by lipofectamine,and then treated with an Akt in-hibitor.The phosphorylation of Akt,cell proliferation and invasion were detected by western blot,MTT assay and Transwell invasion as-say respectively.Results:Protein and mRNA expression levels of IQGAP1 were higher in cancer tissue than in adjacent normal tissue (P <0.05).Transfection of pcDNA3.1 -IQGAP1 increased IQGAP1 expression,enhanced the capability of cell proliferation and inva-sion (P <0.05),increased p Akt level in the cells.Preconditioning with an Akt inhibitor reduced p Akt level.Furthermore,silencing Akt pathway blocked the increase of cell proliferation and invasion induced by IQGAP1 overexpression(P <0.05).Conclusion:IQ-GAP1 overexprission can mediate the ability of proliferation and invasion of OSCC cells by regulating the activation of Akt pathway.

Objective To investigate the clinical efficacy of acupuncture and massotherapy for cerebral palsy-salivation. Method Forty-eight patients with infantile cerebral palsy were randomly allocated to two groups. The control group of 24 patients received acupoint application of Chinese herbal medicine and did the tongue exercises. The observation group of 24 patients received acupuncture and massotherapy in addition. Result Of the control group, five patients were assessed as grade Ⅰ, four patients as grade Ⅱ, 10 patients as grade Ⅲ, two patients as grade Ⅳ and three patients as grade Ⅴ in the TDS grading after treatment. Of the observation group, 10 patients were assessed as grade Ⅰ, seven patients as grade Ⅱ, four patients as grade Ⅲ, two patients as gradeⅣ and one patients as grade Ⅴ in the TDS grading after treatment. The TDS grading assessment was better in the observation group of patients than in the control group. After treatment, middle cerebral artery blood flow velocity and vessel pulsation index were (135.64±13.72)cm/s and (1.05±0.17), respectively, in the control group and (144.78±16.45)cm/s and (0.90±0.18), respectively, in the observation group. There was no statistically significant difference in speech training between the two groups (P>0.05). The number of independent eating patients was significantly larger in the observation group than in the control group; there was a statistically significant difference (P<0.05). Fine action, adaptive behavior and personal social behavior development levels were significantly higher in the observation group than in the control group; there was a statistically significant difference (P<0.05). Both groups of patients could tolerate the therapeutic dosage and course and had no severe adverse reactions. There was no statistically significant difference in safety grade between the two groups (P>0.05). Conclusion Acupuncture and massotherapy is safe and of a fair effect in treating cerebral palsy-salivation. It can increase cerebral blood flow, promote the contraction of local muscles, control salivation and improve the quality of life in cerebral palsy patients.

Objective To investigate the relation between macrophage infiltration and degree of calcific aortic stenosis (CAVS)in elder patients.Methods The aortic valve specimens were collected from 2012 September to 2014 March in Depart‐ment of Cardiac Surgery of Hainan General Hospital ,for operation removal ,from 80 cases[40 males and 40 females ,age:(58 ± 6)years old];normal aortic valve specimens were collected from 7 patients undergoing surgical removal of the normal aortic valve because of aneurysm[4 males ,3 female patients ,aged(41 ± 8)years] ,and 80 healthy adults served as control group.The clinical data of patients were collected ,and CAVS valve and normal valve were observed by HE staining.Expression feature of macrophages was studied by immunohistochemical(IHC)staining.IPP(Image‐Pro Plus)software was used to measure the densi‐ty of macrophages ,and Pearson relation analysis was employed to study the correlation between the density of macrophages and the degree of valve stenosis.Results As compared with healthy adults ,cholesterol and C reactive protein in patients with CAVS were significantly elevated.There were infiltration of inflammatory cells ,new blood capillaries and calcification in the valves of CAVS lesions observed by HE staining.No positive expression of macrophage marker CD68 was found in normal aortic valves , but CD68 positive expression was observed in the valves of CAVS by IHC staining ,and mainly concentrated in the peripheral calcification and osteoid tissues.Simple linear regression analysis showed the density of macrophages was positively correlated with the large pressure gradient(r=0.75 ,P<0.05) ,the average differential pressure(r=0.75 ,P<0.05) ,and the maximum aortic jet velocity(r=0.72 ,P<0.05) ,however ,was negatively correlated(r= -0.71 ,P<0.05)with the valve orifice area .Con‐clusion Compared with healthy adult volunteers ,the concentration of cholesterol and C reactive protein were elevated in blood of the patients with CAVS.Compared with the normal valve ,the macrophages were infiltrated in CAVS valves ;the density of macrophage was positively correlated with the degree of CAVS.

Objective To explore the effects of the multidisciplinary cooperative continue nursing on the quality of life of patients with chronic obstructive pulmonary disease (COPD). Methods From December 2012 to December 2014, hospitalized COPD patients who were in the stable stage of disease and would soon be discharged and met the criteria standards were chosen. Convenient extraction of 64 patients were set as the experimental group in one ward and 50 patients as the control group in the other ward. The conventional discharge guidance was employed in the control group. While the continuation of care before discharge and 1, 3, 6 months after discharge was employed in the experimental group. The indexes such as the quality of life and 6 min walking test distance (6MWD) were observed and compared. Results The total scores and symptoms, activities, influence scores of the quality of life were 48.53±15.78, 35.38± 18.61, 57.95 ±23.69, 52.28 ±15.27 after 6 months intervention in the experimental group and 60.24 ±10.14, 52.76 ±12.36, 68.34 ±15.59, 58.55 ±11.79 in the control group, and there were significant differences (t=-5.69--2.38, P<0.05). 6MWD was (267.46 ±64.64) m after 6 months intervention in the experimental group,which was more than that before intervention (169.42±48.46) m, and there was significant difference (t=-9.71, P<0.01). 6MWD was (201.32±53.93) m after 6 months intervention in the control group, which was not significantly better than that in the experimental group (t=5.82, P<0.01). Conclusions The quality of life of patients with COPD can be significantly improved by the multidisciplinary cooperative continue nursing education after discharge.

Once umbilical cord ligation,neonatal kidney will be responsible for maintaining the whole-body homeostasis and the excretory requirements of the newborn. Meanwhile,there is a significant physiologic changes that occurs during the transition from intrauterine to extrauterine life. Neonatal renal reserve is less than adults,for the structure and function of the kidney still undergo a maturation process. Under the normal condi-tion,the adaptive changes of the renal function,with neonatal growth and development,can keep a delicate bal-ance of the internal environment. If they are exposed to a variety of external stressors,their immature kidney is especially vulnerable,which will not only cause fluid,electrolyte and acid-base imbalances and the adverse prog-nosis,but effect kidney structure and function further mature and increase the long-term risk of chronic kidney disease as well.
