Objective To explore the value of the diagnosis of middle cerebral artery (MCA) stenosis with transcranial Doppler ultrasound (TCD). Methods The clinical data in patients with ischemic cerebrovascular disease examined with digital subtract angiography (DSA)and TCD were analyzed retrospectively. DSA was used as a gold standard to analyze the sensitivity and specificity of the diagnosis of MCA stenosis with TCD. The normal and TCD blood flow velocity with different degrees of stenosis were compared. The best cut-off point of the TCD blood flow velocity of MCA at different degree of stenosis was calculated. Results DSA confirmed that 103 patients had MCA stenosis or occlusion, in which 12 were mild stenosis, 22 were moderate stenosis, 40 were severe stenosis, and 39 were occlusion. Compared to DSA, the sensitivity of TCD in detection of moderate and severe MCA stenosis or occlusion was 78. 8%, the specificity was 96. 0%, and the accuracy was 93. 0%, the missed diagnosis rate was 21. 2%, and the misdiagnosis rate was 4. 0%. As to the blood flow velocity, there was no significant difference between the mild stenosis and normal groups; while there was significant difference between the moderate stenosis and normal groups (P <0. 001). In addition, there was no significant difference in blood flow velocity between the moderate stenosis and severe stenosis groups. Determining the cut-off value of the best peak systolic velocity of the moderate stenosis was 163. 5 cm/s, while the best cut-off value of the mean velocity was 108. 5 cm/s. Conclusions TCD has certain advantages in the diagnosis of the MCA stenosis or occlusion, and it can be used as a safe and inexpensive screening means before DSA examination.

AIM: To explore the expressive role of lipoprotein-associated phospholipase A_2, high sensitive C-reactive protein and matrix metalloproteinase-9 in vulnerable atherosclerotic plaques in a rabbit model. METHODS: Forty eight New Zealand white male rabbits were randomly divided into 4 groups (12 rabbits each): control group, stable plaque group, p53 group, and p53+drug group. Rabbits in control group were fed with a regular diet and underwent sham operation. Rabbits in stable plaque group, p53 group and p53+drug group underwent balloon induced arterial wall injury and then were fed on a diet with 1% cholesterol. The animals were all fed for 3 months, then the rabbits in p53 group and p53+drug group underwent Ad5-CMV p53 transfection at 10th week. Before killed, the animals in p53+drug group underwent pharmacological triggering with Russell's viper venom (RVV) and histamine to induce the rupture of the atherosclerotic plaques. At the 1st day and before sacrifice, the serum was collected for measuring Lp-PLA_2, hs-CRP, MMP-9, HDL, LDL and VLDL. The expressions of Lp-PLA_2, hs-CRP and MMP-9 in tissues were determined by the methods of hybridization and immunohistochemistry. RESULTS: At the end of 12th week, the serum and tissue levels of Lp-PLA_2 and MMP-9 in stable plaque group, p53 group and p53+drug group were significant different from those in control group and in each group at the first day (P<0.05). The serum levels of Lp-PLA_2 and hs-CRP in p53 group and p53+drug group were significantly higher than those in control group and stable group (P<0.05). The serum levels of Lp-PLA_2, hs-CRP and MMP-9 were all significantly different between p53 group and p53+drug group (P<0.05). At the end of 12th week, pathological results showed that 4 groups were normal artery, stable plaque, vulnerable plaque and rupture plaque, respectively. The fabric cap was thicker in plaque groups than that in normal group (P<0.05). The rupture and formation of thrombus were more significant in p53+drug group than those in p53 group. The serum level of Lp-PLA_2 had negative interrelated relationship with fabric cap in plaque groups (r=-0.710, P<0.01), and hs-CRP, MMP-9 had no interrelated relationships with fabric cap in plaque groups. CONCLUSION: Base on the successful establishment of the atherosclerotic plaque animal model, serum Lp-PLA_2 shows better interrelated relationships to plaques stability. Combination with hs-CRP and MMP-9, we can exactly evaluate the nature of plaques.

Objective To explore the short-term hemodynamic change of fluid challenge (FC) with crystalloid or colloid and define fluid responsiveness at the optimal time in patients with septic shock. Methods A prospective observational study was conducted. Septic shock patients monitored with pulmonary catheters admitted to medical intensive care unit (ICU) of the Peking Union Medical College Hospital from July 2016 to December 2018 were enrolled. All included patients received FC and were divided into two groups according to the type of fluid used, i.e. crystalloid group (normal saline for 500 mL) and colloid group (4% succinyl gelatin for 500 mL). The choice of fluid type was decided by the attending physician. Hemodynamic variables were measured at baseline, and 0 (immediately), 10, 30, 45, 60, 90, 120 minutes after FC, included cardiac index (CI), heart rate (HR), mean artery pressure (MAP), central venous pressure (CVP) and pulmonary arterial wedge pressure (PAWP). Fluid responsiveness was defined as CI increased by more than 10% after FC. The data were analyzed by repeated measurements of variance between the two groups as well as responders and nonresponders. Results Forty patients were included, 20 cases each in colloid group and crystalloid group; of whom 26 were fluid responders with 12 of colloid group and 14 of crystalloid group. Of the 14 nonresponders, 8 were of colloid group and 6 of crystalloid group. ① Compared with before FC, CI (mL·s-1·m-2) was significantly increased in crystalloid and colloid groups after FC (71.7±16.7 vs. 65.0±16.7, 68.3±25.0 vs. 63.3±23.3, both P < 0.05). In the colloid group, volume expansion increased the CI to maximum (76.7±18.3) at 30 minutes after FC, at 120 minutes after FC, a significantly higher CI (70.0±16.7) was also observed (P < 0.05), an increased in CI≥10% was observed at 60 minutes after FC. In the crystalloid group, CI was increased to maximum at 10 minutes (73.3±28.3) and decreased to baseline at 60 minutes, an increased in CI≥10% was also observed at 10 minutes after FC. In addition, there was no significant difference in CI changes between colloidal group and crystalloid group at different time points after FC. ② CI did not change over time in nonresponders groups, whereas in responders CI increased parallelly to that in both crystalloid and colloid groups over time. However, an increased in CI≥10% was observed through the 120 minutes after FC in responders of colloid group compared with that of at 30 minutes after FC in crystalloid group. There was significant difference in CI changes between colloidal group and crystalloid group at 30, 45, 60, 90 minutes after FC (mL·s-1·m-2: 18.3±3.3 vs. 8.3±1.7, 18.3±3.3 vs. 5.0±1.7, 13.3±1.7 vs. 3.3±1.7, 11.7±3.3 vs. 3.3±1.7, all P <0.05). ③ The maximal values of CVP and PAWP were observed at the end of FC. In colloid group, both the two variables were notably higher than that before FC over 120 minutes compared with that of only at 10 minutes in crystalloid group. The MAP in colloid increased to maximum immediately at the end of FC and decreased to baseline at 45 minutes, however, the MAP in crystalloid group and HR of both groups showed no differences over 120 minutes. Conclusions Hemodynamic changes were significantly different between crystalloid and colloid after FC in patients with septic shock. Therefore, the timing of fluid responsiveness assessment should be different individually. The assessment time of colloid group may be prolonged to 30 minutes after FC while that of crystal group can be at 10 minute after FC.
