[Objective] To investigate the relationship between the body constitution and the syndromes of the bronchiectasis patients and provide the basis for the clinical treatment.[Methods] Col ected 80 out-patients and in-patients of bronchiectasis in the first affiliated hospital of Zhejiang Chinese Medical University from May 2011 to March 2012. Al patients met with the inclusion criteria, adopted the standardization of physical scale for physical identifica-tion and dialectical type and analyzed the relationship between constitution and syndrome.[Results] ①The gentleness type, qi-deficiency type and yin-defi-ciency type were more popular in the bronchiectasis, fol owed by the phlegm-wet type, wetness-heat type, yang-deficiency type and qi-depression type. The special inherited type and blood-stasis type were very rare. ②The syndrome of phlegm heat obstructing lung was the top one in the Chinese tradi-tional medical syndromes(48.75%).The frequency of liver-fire attacking lung syndrome, hyperactivity of fire due to yin deficiency syndrome and qi-yin de-ficiency syndrome were 21.25%, 18.75% and 11.25% respectively. ③From different body constitution distribution of TCM syndromes in patients with bronchiectasis, it could be found:gentleness type, qi-deficiency type, yang-deficiency type, phlegm-wet type and wetness-heat type were most presented as phlegm-heat stasis lung syndrome. Patients with qi-deficiency type were most presented as qi-yin deficiency syndrome .Patients with Yin deficiency type were always performed as hyperactivity of fire due to yin-deficiency syndrome. Patients with lung qi-stasis type were liver-fire invading lung syn-drome.[Conclusion] Phlegm-heat stasis syndrome was the main syndrome in patients with bronchiectasis. It conformed to the pathological characteristics of deficiency essence with virtual reality. Different body constitutions decided the different traditional Chinese medical syndromes after the disease onset.

Objective To explore the effect of resveratrol on the expression of matrix metalloproteinases-9 (MMP-9) in soluble CD40 ligand (sCD40L)-activated macrophages. Methods Human monocytic cell line THP-1 cells under an inducing of phorbol ester differentiated into macrophages. Then the macrophages were sitimulated by sCD40L independently and after a preincubation with resveratrol. The mRNA expression of MMP-9 and tissue-inhibitor of metalloproteinase-1 (TIMP-1) in macrophages were investigated by semiquantitative RT-PCR. The secretions of MMP-9 and TIMP-1 protein were measured by Western blot. The MMP-9 activity was analyzed by gelatin zymography technique. Results The expressions of MMP-9 gene(1.53±0.04 vs. 0.75±0.01,P＜0.05) and protein(244 930.8±31 268.6 vs. 192 976.8±20 223.1,P＜0.05)were higher in macrophages when stimulated by sCD40L. Resveratrol (10 μmol/L and 50 μmol/L)can inhibit the CD40L-induced gene expression and the protein secretion of MMP-9 (P＜0.01). The activity of MMP-9 was degraded by resveratrol (P＜0.05). Meanwhile resveratrol could increase the gene expression and protein secretion of TIMP-1 (P＜0.05). Conclusions Resveratrol can inhibit the CD40L-activated macrophage expression of MMP-9. It may be one of its mechanisms on antiatherosclerosis and stabilization of atheromatous plaques.

ObjectiveTo investigate the effect of resveratrol on the expressions of E-selectin and monocyte chemoattractant protein-1 (MCP-1) in activated endothelial cells.Methods After being pretreated with resveratrol followed by tumor necrosis factor-α (TNF-α) stimulation, human umbilical vein endothelial cells (HUVEC) were randomly divided into three groups: TNF group,resveratrol+TNF-α group and control group. The expression of E-selectin molecule on the surface of HUVEC was detected by flow cytometric analysis and the mRNA expressions of E-selectin and MCP -1 were determined by semiquantitative RT-PCR. ResultsTNF-α induced the expression of E-selectin and MCP-I of HUVEC.Resveratrol (10 μmol/L) inhibited E-selectin expression.The positive cells of E-selectin in TNF group, resveratrol + TNF-α group and control group were(47.84±3.2)%, (15.3±1.7)% and (3.74±1.6)%, respectively, and the differences among the three groups were statistically significant (P<0.05). Conclusions Resveratrol may contribute to the anti-atherosclerotic effect by inhibiting the expression of E-seleetin and MCP-1 of HUVEC.

Background Resveratrol has been unanimously recognized as an cardiovascular protective substance in red wine. It has been speculated that the anti-atherosclerosis effect of resveratrol is ascribed to its powerful anti-inflammatory effect. Objective To investigate the effects of resveratrol on injured human umbilical veno-endothelial cells (HUVEC) and the reactive oxygen species(ROS) production induced by TNF-? or soluble CD40L (sCD40L). Methods Cultured HUVEC were pre-incubated with resveratrol(1-50 ?mol/L) for 2 hours and then treated with TNF-?(10 ?g/L) or sCD40L?(10 ?g/L) for another 4 hours. MTT assay was used to detect proliterative activity of HUVEC. Immunofluorescence microscopy was used for determination of ROS expression. Results Both TNF-? and sCD40L impaired HUVEC proliferation (-32.7% and -26% vs control,P

Objective: To investigate the proportion of achieving the blood lipid control target and its influencing factors among residents at a high risk of atherosclerotic cardiovascular disease (ASCVD), so as to provide insights into management of blood lipid among residents at a high risk of ASCVD. Methods: Residents at a high risk of ASCVD and at ages of 35 to 70 years were sampled using a multi-stage cluster sampling method from 6 counties (districts) in Shaoxing City from May to July 2021. The residents' demographics, smoking, alcohol consumption and medical history of chronic diseases were collected using questionnaires, the height, weight, waist circumference (WC) and blood pressure were measured, and the total cholesterol (TC), triacylglycerol (TG), low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C) and fasting blood glucose were detected. The proportion of blood lipids achieving the control target was analyzed, and factors affecting the proportion of blood lipids achieving the control target were identified using a multivariable logistic regression model. Results: A total of 1 695 individuals at a high risk of ASCVD were enrolled, including 940 men (55.46%) and 755 women (44.54%), with a mean age of (62.56±6.08) years. There were 285 participants that achieved the target of blood lipid control (16.81%). Multivariable logistic regression analysis identified gender (male, OR=1.962, 95%CI: 1.396-2.758), age (OR=1.037, 95%CI: 1.013-1.061), WC (OR=0.979, 95%CI: 0.964-0.995), diastolic blood pressure (OR=0.981, 95%CI: 0.967-0.994), smoking (OR=1.485, 95%CI: 1.034-2.133), alcohol consumption (OR=0.684, 95%CI: 0.498-0.941), hypertension (OR=1.428, 95%CI: 1.006-2.207), administration of hypoglycemic drugs (OR=2.326, 95%CI: 1.720-3.144) as factors affecting the achievement of the target for blood lipid control among residents at a high risk of ASCVD. Conclusions Individuals at a high risk of ASCVD with higher WC, higher diastolic blood pressure and alcohol consumption are less likely to achieve the target for blood lipid control, while male individuals with older age, hypertension and administration of hypogcemic drugs are more likely to achieve the target for blood lipid control.

Intracranial atherosclerotic disease is one of the main causes of ischemic stroke. Imaging evaluation plays an important role in the formulation of treatment strategies. More and more studies have shown that the changes in hemodynamics after stenosis may have higher predictive value for stroke onset/recurrence compared to the degree of stenosis. This article reviews the evaluation of cerebral hemodynamics in intracranial atherosclerotic diseases.

Objective:To investigate the protective effect of hypothermic antegrade machine perfusion against canine ischemic brain injury.Methods:Thirteen beagle dogs were divided into the mild hypothermia with perfusion group ( n=6) and normothermia with perfusion group ( n=7) according to the random number table. The model of ischemic brain injury was established by neck transection. After 1 hour of ischemic circulatory arrest, the perfusion fluid based on autologous blood was continuously perfused through bilateral common carotid artery for 6 hours. The temperature of the perfusion fluid was set at 33 ℃ in the mild hypothermia with perfusion group and 37℃ in the normothermia with perfusion group, respectively. Blood oxygen saturation was recorded at 0, 1, 2, 3, 4, 5 and 6 hours after the beginning of perfusion to evaluate the perfusate oxygen level. The perfusate was collected, and the levels of Na +, K +, Ca 2+ and glucose as well as the pH value of the perfusate were detected in the two groups. At the end of perfusion, the parietal brain tissues of 1 dog from each group were collected to evaluate the water contents of brain tissues. Nissl staining was used to evaluate the morphological integrity of the pyramidal neurons in the frontal cortex and hippocampus. Neuronal nuclei antigen (NeuN) was used to evaluate the structural and morphological integrity of pyramidal neurons. Immunofluorescence glial fibrillary acidic protein (GFAP) and ionic calcium binding adaptor molecule 1 (Iba1) were used to evaluate the integrity and activity of astrocytes and microglia fragments. Results:At 0, 1, 2, 3, 4, 5 and 6 hours of perfusion, there was no significant difference in the blood oxygen saturation or Na + concentrations between the two groups (all P>0.05); the K + concentrations in the mild hypothermia with perfusion group were (4.57±0.12)mmol/L, (4.67±0.14)mmol/L, (4.27±0.12)mmol/L, (4.45±0.10)mmol/L, (6.60±0.15)mmol/L, (7.37±0.18)mmol/L and (9.03±0.16)mmol/L, respectively, which were significantly lower than those in the normothermia with perfusion group [(4.84±0.10)mmol/L, (5.31±0.13)mmol/L, (5.44±0.24)mmol/L, (5.70±0.18)mmol/L, (7.79±0.18)mmol/L, (10.44±0.40)mmol/L, (10.40±0.41)mmol/L] (all P<0.01). At 0, 1, 2 and 3 hours of perfusion, the Ca 2+ concentrations in the mild hypothermia with perfusion group were (0.72±0.15)mmol/L, (1.55±0.16)mmol/L, (1.62±0.15)mmol/L and (1.88±0.15)mmol/L, respectively, being significantly higher than those in the normothermia with perfusion group [(0.41±0.13)mmol/L, (0.99±0.12)mmol/L, (1.29±0.13)mmol/L, (1.57±0.11)mmol/L] (all P<0.01), and no significant differences were found at other time points (all P>0.05). At 0, 1 and 2 hours of perfusion, the glucose concentrations in the mild hypothermia with perfusion group were (5.75±0.19)mmol/L, (5.17±0.15)mmol/L and (4.72±0.15)mmol/L, respectively, being significantly higher than those in the normothermia with perfusion group [(5.30±0.22)mmol/L, (4.89±0.20)mmol/L, (4.30±0.17)mmol/L] (all P<0.01), with no significant differences found at other time points (all P>0.05). At 2, 3, 4, 5 and 6 hours of perfusion, the pH values of the mild hypothermia with perfusion group were 7.32±0.06, 7.25±0.02, 7.23±0.02, 7.24±0.02 and 7.24±0.02, respectively, being significantly higher than those in the normothermia with perfusion group (7.26±0.01, 7.21±0.01, 7.17±0.02, 7.15±0.02, 7.08±0.02) ( P<0.05 or 0.01), with no significant differences at other time points (all P>0.05). The water content of brain tissues in the mild hypothermia with perfusion group was (74.9±0.4)%, which was significantly lower than (79.9±0.9)% in the normothermia with perfusion group ( P<0.01). Nissl staining showed that the pyramidal neurons in prefrontal cortex and dentate gyrus had good integrity in the mild hypothermia with perfusion group. NeuN immunofluorescence staining showed that the morphology and structure of pyramidal neuron cells in the mild hypothermia with perfusion group were better with clearly visible axons than those in the normothermia with perfusion group, whereas the cytosol was full and swollen with scarce axons in the normothermia with perfusion group. GFAP and Iba1 immunofluorescence staining showed that more structurally intact glial cells, more abnormally active cells, thickener axons and better axon integrity in all directions were found in the mild hypothermia with perfusion group than those in the normothermia with perfusion group. Conclusion:Compared with normal temperature antegrade mechanical perfusion, the mild hypothermia antegrade mechanical perfusion can protect canine brain tissue and alleviate ischemic brain injury by maintaining stable energy and oxygen supply, balancing ion homeostasis and perfusion fluid pH value, reducing tissue edema, and maintaining low metabolism of pyramidal neurons, astrocytes and microglia.
