Objective To observe the effects of different posture on hemodynamics and plasma atrial natriuretic polypeptide(ANP) during laparoscopic surgery. Methods Forty patients who scheduled for elective laparoscopic surgery under general anesthesia were allocated into two groups according to their posture during laparoscopic surgery,20 cases for each group. In group A, the patients were arranged in a head-down tilt position, in group B, the patients were arranged in a head-up tilt position systolic blood pressure (SBP),diastolic blood pressure (DBP),central venous pressure (CVP) and electro cardio gram (ECC) were monitored continuously. Blood samples were taken from central venous at four time points of prepneumoperitoneum(T1), 10 minutes after that(T2) and 20 mintues(T3) when the patients were arranged at the different operation-needed position with a stable pneumoperitoneum pressure of 14 mm Hg (1 mm Hg = 0.133 kPa),and at 5 minutes (T4) after deflation of pneumoperitoneum when the patients returned to supine position. The plasma ANP was assessed by radioimmunoassay. Results In group A,the CVP at T2 and T3 [(14.45 ±2.72),(14.20 ±2.46) mm Hg] was significantly higher than that at T1 [(6.05 ±1.76) mm Hg] (P<0.01), in group B,the CVP at T2 and T3 [(8.90±1.27),(9.02 ±0.47) mm Hg] was significantly higher than that at T1[(6.30 ±1.34) mm Hg](P< 0.01) ,with a higher level in group A than those in group B at the same time point during pneumoperitoneum(P< 0.01). The ANP level in group A was higher at T2 than that at T1, and there was significantly higher at T3 than that at T1 (P < 0.05). But the ANP level was significantly higher in group A than that in group B at the same time points of T2 and T3 (P < 0.05). Conclusion The posture may have obvious effect on CVP and plasma ANP level during laparoscopic surgery.

Objective To evaluate the clinical value of the regional wall motion in patients with suspected coronary artery disease by real-time three-dimensional echocardiography (RT-3DE) and two-dimensional speckle tracking imaging (2D-STI). Methods A total of 143 hospitaized patients with suspected coronary artery disease and normal wall motion de?tected by two-dimensional echocardiography (2DE) were enrolled and devided into group A (coronary stenosis ≥75%) 73 cases and group B (coronary stenosis<75%) that include 70 cases according to coronary angiography results. Left ventricu?lar segmental ejection fraction (sEF) was measured by RT-3DE and peak systolic longitudial strain (SL) was measured by 2D-STI. ROC curves of the two measurements were generated and compared. Differences in sEF and SL between group A and group B were respectively analyzed. Results (1)Both sEF of RT-3DE and SL of 2D-STI in group A were significantly low?er than those in group B (P<0.05);(2)sEF was positively correlated with SL(r=0.689,P<0.05);(3)Compared with SL, sEF had larger area under ROC curve in some segments of left ventricle where both parameters are abnormal for the diagnosis of the coronary stenosis ≥75% (0.922 vs 0.874). Conclusion Regional wall motion of left ventricular can be measured by both RT-3DE and 2D-STI which can be both used to estimate the extend of stenosis of coronary artery. And RT-3DE is su?perior over 2D-STI.

OBJECTIVE: To observe the effects of Feiji Formula, a compound traditional Chinese herbal medicine, on lung cancer metastasis in mice. METHODS: The lung cancer metastasis model of mice was established in this experiment study. Twenty-four mice were randomly divided into three groups: untreated group, cisplatin group and Feiji Formula group. Mice in the Feiji Formula group were treated with Feiji Formula decoction; in cisplatin group, with cisplatin by intraperitoneal injection; and in the untreated group, with normal saline (NS). After twenty-day treatment, the body and tumor weights as well as the number of metastatic tumors in both lungs of each mouse were measured. RESULTS: The body weight of mice in cisplatin group was significantly less than that of Feiji Formula group and untreated group (P<0.01); the tumor weight of mice in cisplatin group and Feiji Formula group was markedly lower than that of untreated group (P<0.01); and the number of metastatic tumors in cisplatin group and Feiji Formula group was markedly lower than that of the untreated group (P<0.01), no significant difference between the Feiji Formula group and cisplatin group in terms of the weights and the numbers of metastatic tumors in bilateral lungs. CONCLUSION: Feiji Formula can suppress tumor growth and decrease the number of lung metastatic tumors in the mice, and maintain the body weight of the mice.

Objective: To study the relationship between Framingham risk score for coronary artery disease (CAD) and cognitive function in healthy community elders.
Methods: A total of 276 healthy community elders were evaluated by Framingham score to predict the risk for suffering from CAD in 10 years. The subjects were divided into 3 groups. High risk group (the risk > 20%), n=46, Mid risk group (the risk at 10%-20%), n=76 and Low risk group (the risk < 10%), n=154. The cognitive function was measured by mini-mental state examination (MMSE) and China adult intelligence scale (CISA). The differences of cognitive function levels to 3 CAD risk groups were studied.
Results: With the increased CAD incidence from Low risk, Mid risk to High risk groups, the MMSE score reduced accordingly (26.9 ± 1.45) vs (24.3 ± 1.53) vs (22.2 ± 1.43), P=0.014. Pearson analysis presented that MMSE score was negatively related to Framingham risk score (r=-0.213, P<0.001). There were several elements of cognitive function related to Framingham risk score including MMSE score, question answering, grid filling, oral arithmetic and word distinguishing (r=-0.247), (r=-0.167), (r=-0.132), (r=-0.152) and (r-0.256), all P<0.05.
Conclusion: CAD risk level was negatively related to cognitive function, the higher Framingham risk score resulted in the lower cognitive function in healthy community elder subjects.

BACKGROUND: The formation of long-term memory includes acquisition, consolidation and reconsolidation. Reconsolidation is very important for the new memory transforming into stable memory. Stress is an important environmental factor in the process of learning and memory. Corticosterone is very important for stress response. At present, research about the impact of corticosterone on reconsolidation of novel object recognition memory is less. Thus, it is very important to test the impact of corticosterone on reconsolidation of novel object recognition memory in rats.
OBJECTIVE: To analyze the effects of corticosterone on the reconsolidation of novel object recognition memory in rats.
METHODS: (1) The rats were intraperitoneal y injected with corticosterone (0.1, 1 and 3 mg/kg) immediately after reactivation. The discrimination index was used to assess memory performance and calculated as the difference in time exploring the novel and familiar objects. (2) The rats were intraperitoneal y injected with corticosterone (3 mg/kg) 6 hours after reactivation. The discrimination index was used to assess memory performance and calculated as the difference in time exploring the novel and familiar objects. (3) The rats were intraperitoneal y injected with corticosterone 3 mg/kg without reactivation. The discrimination index was used to assess memory performance and calculated as the difference in time exploring the novel and familiar objects.
RESULTS AND CONCLUSION: Immediate injection of corticosterone 3 mg/kg after reactivation significantly decreased the discrimination index. At 6 hours after reactivation or without reactivation, corticosterone administration did not impact the discrimination index. These results confirmed that corticosterone administration immediately after reactivation impairs the reconsolidation of novel object recognition memory. The damage effect depends on the reactivation experience and the specific time window after reactivation.
