Objective To investigate the application of neuronavigator in the resection of neurospongioma and management of brain shift.Methods Operation protocol was made according to three dimensional structure of neumspongioma under neuronavigation.The focus was sought by using viewing wand for the resection.Results All focus were removed under neuronavigator.The size and operation time was associated with brain shift along the operation pathway.Operative approach and depth of lesion was related to brain shift.Loss of large volume of cerebrospinal fluid exerted influences on the shift of codex along the operative pathway and plane side.Conclusion Neuronavigator can effectively protect nerve function when used in the resection of neurospongioma.As for brain shift,strict navigation and operative procedure would be useful for reducing loss of cerebrospinal fluid,removed volume of brain tissue and avoiding early release of tumor hydatid flui.

Objective To study the relationship between insulin resistance and renin-angiotensin-aldosterone system (RASS) in newly diagnosed type 2 diabetes mellitus, and to provide the best treatment for type 2 diabetes mellitus with hypertension . Methods Ninety cases of newly diagnosed type 2 diabetes mellitus were included. After stratified by gender, all the patients were divided into hypertension group and non-hypertension group. According to whether taking hypotensor, the patients with hypertension were further divided into non-medication group, calcium channel blockers (CCB) group, and angiotensin receptor blockers (ARB) group respectively. Results In female patients with hypertension, the IAI, levels of rennin and angiotensin II were higher than those in non-hypertension group and the systolic pressure of female patients taking ARB was lower than those taking CCB. Pearson′s correlation analysis showed that angiotensin II and aldosterone was positively correlated with HOMA-IR but negatively correlated with IAI in females. Conclusions In female newly diagnosed type 2 diabetes mellitus , RASS is related to the development of insulin resistance , so RASS antagonists are the first choice to achieve better blood glucose control in female patients.

Objective To investigate the metabolites of serum samples from liver cirrhotic patients with or without minimal hepatic encephalopathy,and even overt hepatic encephalopathy,then to find out diagnostic markers for minimal hepatic encephalopathy.Methods High performance liquid chromatography-orbit trap mass spectrometry (UPLC/LTQ-Orbit trap MS) technology was applied to analyze the serum metabolites from 38 patients of liver cirrhosiswith hepatitis B and 33 healthy volunteers.Results The serum metabolites of patients with simple liver cirrhosis were different from those of patients with minimal or overt hepatic encephalopathy.The serum metabolites of patients with minimal hepatic encephalopathy was mostly similar with those of overt hepatic encephalopathy patients.Arginase,L-tyrosine,glutamic acid,two L-phenylalanine peptide,homovanillic acid,omithine,L-serine were increased in patients with minimal or overt hepatic encephalopathy,and hypoxanthine decreased in patients with minimal or overt hepatic encephalopathy patients.Conclusions The serum metabolites of patients with minimal hepatic encephalopathy are mostly similar to those of patients with overt hepatic encephalopathy.Arginase,L-tyrosine,glutamic acid,two L-phenylalanine peptide,homovanillic acid,ornithine,L-serine maybe the early metabolites biomarkers to diagnose minimal hepatic encephalopathy.Hypoxanthine is likely to be an effective complement to treat patients with hepatic encephalopathy.

Objective:To confirm the correlations between the soma ofthe traditional Chinese Medicine and the objective index about Homeostasis model assessment-Insulin Resistance index(HOMA-IR)and the function about beta Cell ofislet(HOMA-?)with Impaired glucose regulation(IGR),to explore the basis for the syndrome ofthe traditional Chinese Medicine and insulin function.Methods:According from the epidemiological investigation,we had a Oral Glucose Tolerance Test and insulin releasing test to the 1 500 persons who came from downtown area、county、small towns、village,in accordance with the soma ofTCM,then investigate and analysis the correlations who meet the diagnosis ofIGR.Results:①In all 322 cases,each ratio ofthe group about signal soma、twice soma、three soma is 74.8%、19.5%、8.1%,Ahead somas are mild, deficiency ofQi, deficiency ofYang, deficiency ofQi and Yang,phlegmatic hygrosis.②The BMI ofmild group is higher than the deficiency ofQi,deficiency ofYang,deficiency ofQi and Yang group(P

Adult male rats were divided at random into two groups and trained on the treadmill running schedules, 60 min/day and 10min/day for group A and B separately. Four weeks later the ultrastructure of the left ventricular myocardium was examined and the specific surface of mitochondria wasmeasured. Comparing to the corresponding control group, the specific surface of mitochondria in the two groups of trained rats was decreased significantly. (5.883+0.12 um and 6.050?0.12 um to 6.564?0.17 um). This means myocardium mitochondria in trained rats were swelling. The reason might be that the myocardium injury was induced by exercise training.

ObjectiveTo investigate the relationship of blood glucose,blood lipids,serum uric acid,fibrinogen level and prognosis of patients with acute lacunar cerebral infarction.MethodsClirical data of 127 cases with acute lacunar cerebral infarction were retrospectively analyed.Patients with normal blood glucose,blood lipid,uric acid and fibrinogen level were enrolled into A group of 64 cases,63 cases with abnormal levels were selected as group B,an average of 2 years of follow-up,observing the two groups of neurologic,re-infarction incidence and prevalence of vascular dementia were obsenved in two groups.ResultsAfter 4 weeks of treatment,A group of neural function defect score(9.6 ±7.3) was significantly lower than group B( 14.3 ±7.4) (t =3.8696,P ＜0.05) ;95.4％ total effective rate in A group was significantly higher than B group of 82.0％ ( x2 =5.8623,P ＜ 0.05 ).After an average follow-up of 2 years,A group of recurrent cerebral infarction rate( 18.8％ ),vascular dementia rates(7.8％ ),were significantly lower than group B(28.6％),17.5％(11/63)(x2 =6.5421,5.9623,P＜0.05).ConclusionA number of abnormal serum biochemical indexes had a significant impact on short and long-term prognosis of acute lacunar cerebral infarction.

Objective To study the effect of myocardial infarction induced by distal left ascending artery occlusion on left ventrieular(LV) synchronism. Methods Routine echocardiography and vector velocity imaging were performed within 2 hours before and 7-14 days after myocardial infarction by occluding distal left ascending coronary arteries in experimental pigs. Routine eehocardiographie parameters of LV, including end diastolic and systolic diameters, volumes, and spherical indexes were measured or calculated. Six segmental peak systolic velocity, strain and strain rate were compared between pre- and post-myocardial infarction. Results After myocardial infarction, LV end diastolic, end systolic long diameter and end systolic volume increased with decreased ejection fraction. With the 6 segmental systolic velocity, strain and strain rate significantly reduced,the mean 6-segmental time to peak strain rate delayed significantly. Conclusions Abnormal synchronism after myocardial infarction may aggravate LV systolic dysfunction.

Objective To evaluate transport efficiency and safety by process management during the handover of patients with tracheal intubation post-operation. Methods Prospective studies were performed between patients with or without process management during the handover. The time of handover were recorded and compared. The difference between systolic and diastolic blood pressure, heart rate, and arterial oxygen saturation were also recorded and compared. The adverse events during the handover were also investigated. Results It costed less time in the handover of patients under process management with significant difference[(4.75±0.54) min vs. (7.05±0.88) min, t=-17.21, P<0.01]. The incidence rate of harmful cases in the handover of patients under process management was significantly declined than that without process management[ 1.67%(1/60) vs. 13.33%(8/60),Χ2=4.324 3,P<0.05 ]. Conclusions Process management may facilitate the handover of patients with tracheal intubation post-operation and improve its safety.
