Objective To investigate a new method using Image-Pro Plus (IPP) combined with Photoshop image analysis software to quantitatively measure the changes in microcirculation in hippocampus.Methods Twenty-two Japanese white rabbits that had received bilateral carotid artery ligation for 2 weeks without neurological dysfunction were divided into a subarachnoid hemorrhage (SAH) group and a control group, 11 rabbits in each group. The rabbit model of symptomatic cerebral vasospasm was established by the method of twice injecting blood into occipital cistern. On the 7th day after the first time of injecting blood, the rabbits were sacrificed, cerebral perfusion fixation was carried out, the hippocampus was harvested, and CD34 was determined by immunohistochemical determination. IPP 6.0 combined with Photoshop image analysis software was used to quantitatively measure the count of hippocampal microvessels density (MVD) and the field (for statistics)/microvascular capillary area ratio was calculated.Results CD34 could effectively identify microvascular endothelial cells, and using IPP 6.0 could automatically and accurately calculate MVD and field (for statistics)/micrevascular area ratio in hippocampus. Compared with the control group, in SAH group, the MVD and the area ratio in hippocampus were significantly reduced, the differences being statistically significant [MVD (count/area): 3.87±0.67 vs. 5.17±0.53, area ratio: (0.86±0.20)% vs. (1.40±0.17)%, bothP < 0.05].Conclusions CD34 can be used to identify microvessels, IPP 6.0 image analysis software co-Photoshop is a high efficient and accurate new method to measure the microvessels count and calculate the field/microvessel area ratio, not only it is easy to operate, but also the data can be automatically calculated and generated, reflecting precisely the changes in microcirculation in hippocampus after symptomatic cerebral vasospasm in rabbits.

Objective To study the effect and mechanism of dexmedetomidine combined with sufentanil on postoperative analgesia in elderly patients with abdominal surgery. Methods Ninety-six elderly patients having undergone abdominal surgery in the First Affiliated Hospital of Wenzhou Medical University from January 2016 to June 2017 were enrolled, and they were divided into a control group and an observation group by random number table method, 48 cases in each group. General anesthesia was performed in the operation, and after surgery venous analgesic pump was used for analgesia in both groups. Analgesic method: the control group was given sufentanil 2 μg/kg and tropisetron 5 mg; the observation group was given dexmedetomidine 2 μg/kg, sufentanil 2 μg/kg and tropisetron 5 mg. The changes of pain and sedation score, conventional indexes [systolic blood pressure (SBP), diastolic blood pressure (DBP), heart rate (HR), respiratory rate (RR), pulse blood oxygen saturation (SpO2)], oxidative damage indexes [lipid peroxide (LPO), glutathione peroxidase (GSH-Px), Cu-Zn superoxide dismutase (Cu-Zn SOD)], stress response indexes [cortisol (Cor), epinephrine, norepinephrine (NE)], platelet activation indexes granule membrane protein-140 (GMP-140), thromboxane A2(TXA2) and the incidence of adverse reactions were observed in both groups. Results ① After surgery the visual simulation score (VAS) and Ramsay score in both groups were higher than those before surgery, and showed a tendency firstly increased and then decreased, and reached to peak value 2 hours after operation [VAS score:the control group was 3.24±0.98 vs. 1.95±0.93, observation group was 3.19±1.03 vs. 1.98±0.95; Ramsay score:the control group was 3.26±0.51 vs. 1.90±0.45, observation group was 3.77±0.53 vs. 1.92±0.42], began to decline 6 hours after operation, reached to valley value 48 hours after operation, and there was no significant difference in VAS scores between the two groups (2.02±0.64 vs. 1.98±0.95), Ramsay score was significantly higher in observation group than that in control group (2.59±0.41 vs. 2.10±0.21). ② Since 2 hours after the operation, the SBP, DBP, HR and RR in the observation group began to be lower than those in control group, 12 hours after surgery their values reached their valleys [SBP (mmHg, 1 mm Hg = 0.133 kPa): 113.2±13.5 vs. 122.1±10.3, DBP (mmHg): 67.5±9.9 vs. 76.4±8.6, HR (bpm): 64.5±6.9 vs. 71.4±7.5, RR (bpm): 14.8±1.1 vs. 15.8±0.8, all P < 0.05]; while SpO2did not change a great deal. ③ LPO, Cor, epinephrine, NE, GMP-140, TXA2of two groups after operation were higher than those before operation, GSH-Px and Cu-Zn SOD were lower than those before operation. However, LPO, Cor, epinephrine, NE, GMP-140, TXA2in observation group were significantly lower than those in control group [LPO (μmol/L): 6.4±0.8 vs. 9.8±1.1, Cor (ng/L): 148.2±19.1 vs. 239.3±27.8, epinephrine (μg/L): 124.2±13.9 vs. 207.1±23.5, NE (μg/L): 109.2±14.8 vs. 183.3±21.6, GMP-140 (μg/L): 27.13±3.82 vs. 39.06±4.83, TXA2(ng/L): 422.30±53.74 vs. 610.43±73.21, all P < 0.05], GSH-Px and Cu-Zn SOD in observation group were significantly higher than those in the control group [GSH-Px (U/L): 426.7±58.7 vs. 307.9±51.2, Cu-ZnSOD (μg/L): 311.3±42.5 vs. 231.6±34.1, all P < 0.05].④ The incidence of adverse reaction nausea in the observation group was significantly lower than that in the control group [4.17% (2/48) vs. 37.5% (18/48)].

Objective:To investigate the application value of transcranial Doppler (TCD) in the prognosis assessment of nerve function in patients with acute cerebral infarction (ACI) after intracranial mechanical thrombectomy.Methods:A retrospective analysis was conducted. The clinical data of 43 patients with acute anterior circulation cerebral infarction who received intra-arterial mechanical thrombotomy for recanalization admitted to Taizhou Central Hospital from January 2018 to December 2019 were analyzed. The modified Rankin scale (mRS) score of patients were followed up by telephone at 3 months after surgery to evaluate the prognosis of neurologic outcome. Patients with mRS score 0-2 were enrolled in the good prognosis group, while those with a score of 3-6 were enrolled in the poor prognosis group. The gender, age, past history, underlying diseases, occluded arteries, atherosclerotic stenosis and bridging treatment, time from onset to reperfusion, blood flow dynamics under TCD at 1 day after thrombectomy, and National Institutes of Health stroke scale (NIHSS) scores before and 1, 7, and 14 days after thrombectomy were compared between the two groups. Multivariate Logistic regression analysis was used to screen the prognostic factors of nerve function at 3 months after mechanical thrombectomy in patients with ACI. The receiver operating characteristic (ROC) curve was drawn to evaluate the prognostic value for neurological function assessed by TCD.Results:Forty-three patients were enrolled in the final analysis, with 23 patients in the good prognosis group and 20 in the poor prognosis group. The recanalization was successfully achieved in both groups without complications. However, the hemodynamics of intracranial arteries evaluated by TCD 1 day after operation in both groups still showed partial or complete occlusion, and the hemodynamics of patients in the poor prognosis group was worse than that in the good prognosis group (poor blood flow: 40.0% vs. 0%, inadequate blood flow: 30.0% vs. 17.4%, good blood flow: 30.0% vs. 82.6%), and the differences were statistically significant (all P < 0.01). Before thrombotomy, there was no significant difference in NIHSS score between the two groups. After thrombotomy, the NIHSS score of the two groups gradually decreased with the extension of time, but the NIHSS score at 14 days after operation of the poor prognosis group was still significantly higher than that of the good prognosis group (10.55±2.93 vs. 4.65±1.70, P < 0.01). Univariate analysis showed that compared with the good prognosis group, the proportion of patients with diabetes and arteriosclerosis stenosis in the poor prognosis group were significantly increased (30.0% vs. 4.3%, 45.0% vs. 17.4%, both P < 0.05), and the time from onset to reperfusion was prolonged (minutes: 385.9±96.2 vs. 294.5±95.1, P < 0.01). Multivariable Logistic regression analysis showed that the therosclerosis stenosis [odds ratio ( OR) = 9.334, 95% confidence interval (95% CI) was 1.092-79.775, P = 0.041] and the reperfusion time ( OR = 1.016, 95% CI was 1.006-1.027, P = 0.002) were associated with prognosis of nerve function at 3 months after mechanical thrombectomy in patients with ACI. ROC curve analysis suggested that the evaluation of intracranial hemodynamics by TCD might be able to predict the prognosis of neurological function in patients with ACI after 3 months of intracranial mechanical thrombectomy, the area under ROC curve (AUC) was 0.768 (95% CI was 0.620-0.917), the sensitivity was 65.0%, the specificity was 87.0%, the positive predictive value was 82.6%, and the negative predictive value was 70.0%. Conclusion:The evaluation of intracranial hemodynamics assessed by TCD is helpful in early judging the prognosis of neurological function in patients with ACI after intracranial mechanical thrombectomy.

OBJECTIVETo investigate the role of NF-κB/survivin signal pathway in the intima hyperplasia of rat carotid balloon injury restenosis model.
METHODSNF-κB siRNA lentivirus vector (titer was 1 × 10⁸ TU/ml) was established. Carotid balloon injury restenosis model was made in 33 SD rats. The rats were divided into 4 groups according to different processing methods, including negative control (NC) group (n = 11), NF-κB siRNA group (n =11), NF-κB siRNA+YM155 (survivin inhibitor) (n = 11), the uninjured carotid artery served as the normal control group (n = 11). After 7 days, the carotid sample (n = 5 each group) were harvested to detect the NF-κB and survivin mRNA expression by RT-PCR.The carotid sample were harvested on 28 days (n = 6 each group) for HE staining and measuring intima hyperplasia. Immunohistochemical method was also used to detect the expression of intima proliferation cell nuclear antigen (PCNA) and media α-SM-actin.
RESULTS(1) After 7 days, NF-κB and survivin mRNA expression was significant higher in NC group than in normal control group (P<0.05), the NF-κB mRNA expression was significantly lower in NF-κB siRNA group than in NC group (P<0.05) and similar between NF-κB siRNA group and NF-κB siRNA+YM155 group. The survivin mRNA expression was significantly lower in NF-κB siRNA group compared to NC group (P<0.05) and significantly higher in NF-κB siRNA group than in NF-κB siRNA+YM155 group (P<0.05). (2) After 28 days, intima hyperplasia was observed in NC (0.13 ± 0.01), NF-κB siRNA (0.11 ± 0.01) and NF-κB siRNA+YM155 group (0.09 ± 0.01) mm² (P<0.05). Media area was similar among NC group, NF-κB siRNA group and NF-κB siRNA+YM155 group (P>0.05). I/M ratio was gradually reduced among NC group (1.55 ± 0.07), NF-κB siRNA group (0.92 ± 0.08), NF-κB siRNA+YM155 group (0.76 ± 0.06, all P<0.05). Similar results were found in the residual restenosis rate: NC group (58.71 ± 0.02) %, NF-κB siRNA group (32.13 ± 0.05) %, NF-κB siRNA+YM155 group (26.42 ± 0.03) % (all P<0.05) and expression of vascular smooth muscle cell PCNA: NC group (45.32 ± 7.21) %, NF-κB siRNA group (36.54 ± 6.42) %, NF-κB siRNA+YM155 group (28.57 ± 6.31) % (all P<0.05). On the contrary, the IOD of α-SM-actin in media increased gradually: NC group (0.055 ± 0.006), NF-κB siRNA group (0.072 ± 0.011), NF-κB siRNA+YM155 group (0.084 ± 0.008, all P<0.05).
CONCLUSIONInhibiting NF-κB expression can significant decrease intima hyperplasia in this model, and this effect may be mediated by inhibiting survivin and reducing the proliferation of vascular smooth muscle cells.

Spasticity is one of common manifestations of upper motor neuron injury, and often evaluated with semi-quantitative scales. Ultrasound elastography (UE) can provide elastic information for muscle tissue, and can be used for the evaluation of muscle tension after cerebral palsy and stroke, as well as the efficacy of treatment. It correlates well with clinical spasm rating scales. However, UE may also be used for assessment of spasticity after spinal cord injury and multiple sclerosis, etc.
