Ezrin is an important membrane-cytoskeleton linker protein.It is highly related with tumor invasion and metastasis and indicates poor prognosis.It is reported that aberrant Ezrin expressed in many carcinomas,such as osteosarcoma and breast carcinoma.However,the complex mechanisms of Ezrin in tumor invasion and metastasis remain unclear.It is involved in several different tumor associated signal pathway based on different tumor types,including adhesion molecule signal transduction,Rho and Akt signal transduction.Therefore,research on the signal transduction of Ezrin has great significance for the understanding of cancer progression and Ezrin is probable to be a new treatment target.

OBJECTIVE: To explore the effects of Scrophulariae of cold nature and Aconite of hot nature on myocardial hypertrophy and neuroendocrine factors in rats and mice. METHODS: A mouse model of myocardial hypertrophy was established by hypodermic injection of isoproterenol. Sixty myocardial hypertrophy mice were randomly divided into five groups: normal control group, untreated group, metoprolol-treated group, Scrophulariae-treated group and Aconite-treated group. A rat model of myocardial hypertrophy was established by peritoneal injection of L-thyroxin. Fifty rats were randomly divided into five groups: normal control group, untreated group, captopril-treated group, Scrophulariae-treated group and Aconite-treated group. After 7-9 days of treatment with intragastric administration of the corresponding drugs, the effects of Scrophulariae and Aconite on left ventricular weight index (LVWI) and heart weight index (HWI) were determined. The concentrations of cyclic adenosine monophosphate (cAMP) in plasma and angiotensin II (Ang II) in myocardium were detected through radio-immunity method. Cardiocyte cross-section area was determined by using HE staining. RESULTS: Scrophulariae of cold nature could significantly reduce the LVWI, HWI and cardiocyte cross-section area, and could decrease the content of cAMP and Ang II. However, Aconite had no such effects. CONCLUSION: Scrophulariae of cold nature can inhibit myocardial hypertrophy through restraining the activity of sympathetic nervous system and decreasing the level of Ang II. The inhibition of Aconite of hot nature on cardiac hypertrophy is not significant.

Objective To investigate the early predictive indexes of curative effect of acute respiratory failure(AFR) treated with noninvasive bilevel positive airway pressure(BiPAP) ventilation.Methods Sixty-eight patients with AFR were treated with BiPAP ventilation.According to the therapeutic outcome,patients were divided into success group and failure group,and the distributions of ages,acute physiology and chronic health evaluation(APACHEⅡ) score,consciousness level as well as arterial blood gas(ABG) measurement before and after the treatment with BiPAP ventilation were compared between the two groups.Results There was statistical difference in the ABG levels of pH and PaCO_2 after 1 hour's treatment with BiPAP ventilation(P0.05).Conclusion The levels of pH and PaCO_2 after 1 hour's treatment with BiPAP ventilation are valuable markers for curative effects in early stadge.If the levels of pH and PaCO_2 fail to improve,the treatment with intubation may be necessary.

PURPOSE To investigate the indications for surgical treatment of peripheral neurofibroma and the cause of postoperative recurrence.METHODS Analysis of the clinical data of 15 cases of limb neurofibroma in different locations,whichhave been operated 16 times.RESULTS Neurofibroma normally grows in two ways:along nerve cord and in plexiform.The former can be excised along tumor edge and the latter should be removed extensively.Pathological studies were performed postoperatively,and confirmed that it was neurofibroma.13 of 15 cases have been followed up on average 3.4 years.No cases had recurrence except 1 case after a half year which was reoperated and has not recurred for 8 months up to now.CONCLUSION If the patients have pain or discomfort,limb malfunction or disfigurement,operation should be done in the early stage.Different operative methods were chosen due to different types of neurofibroma.Rccurrence is related to the extent of operation

Objective To study changes of serum IL-17 and IL-35 levels in patients with heart failure. Methods 60 patients with heart failure (observation group)were selected as research subjects.60 patients accord-ing to different severity were divided into acute period heart failure (34 cases)and stable stage heart failure (26 ca-ses);60 patients graded according to the NYHA standards were divided into 24 cases of heart failure with grade Ⅱ, 20 cases of grade Ⅲ ,16 cases of grade Ⅳ.According to the different primary diseases :expansion cardiomyopathy group (20 cases in group A),the coronary heart disease group (group B,24 cases),hypertensive heart disease group (group C,16 cases).During the same period,42 healthy elderly people in our hospital were selected as control group. The serum IL-17,IL-35 levels were tested,and the serum IL-17,IL-35 levels in patients with heart failure were ana-lyzed.Results Serum level of IL-17 in the observation group was higher than the control group,and the difference was significant [(15.61 ±4.02)pg/mL vs (9.49 ±3.96)pg/mL,t =9.018,P <0.01].Serum level of IL-35 in the observation group was significantly lower than that of the control group,and the difference was significant[(52.78 ± 4.29)pg/mL vs (61.49 ±4.81)pg/mL,t =11.963,P <0.01].The level of serum IL-17 in acute stage of patients with heart failure was higher than that of stable heart failure,and the difference was significant (t =6.278,P <0.01);IL-35 level in serum of patients with heart failure in acute phase was lower than that of stable heart failure,the difference was significant (t =9.529,P <0.01).With the increase in heart failure grade,serum IL-17 level showed a rising trend,and the differences among three groups had statistical differences (F =6.098,P <0.01);serum IL-35 level decreased,and the differences among three groups had statistical differences(F =8.978,P <0.01).The serum IL-17 level of A group was higher than that in B group and C group,there were significant differences (F =6.096, P <0.01),the serum IL-17 level between B group and C group had no statistical difference (t =0.172,P >0.05). The serum IL-35 level of A group was lower than that of B group and C group,there were significant differences (F =8.978,P <0.01),the serum IL-35 level between B group and C group had no statistical difference (t =0.208,P >0.05).Serum IL-17 and serum IL-35 level was negatively correlated (r =-0.429,P =0.009).Conclusion High expression of IL-17 in elderly patients with heart failure,while IL-35 decreased in elderly patients with heart failure, IL-17,IL-35 are closely related to the senile congestive heart failure and the severity of illness.Serum IL-17 is nega-tively correlated with the level of serum IL-35.
