Objective To identify the risk factors for the development of hypotension during craniotomy in patients with severe traumatic brain injury (TBI).Methods One hundred and seventy-five patients,aged ≥ 18 yr,undergoing emergency craniotomy for TBI,were selected.According to the occurrence of intraoperative hypotension (systolic pressure ＜ 90 mm Hg or the decreased amplitude ＞ 30％ of the baseline),all the patients were divided into 2 groups:hypotension group and non-hypotension group.The data including gender,age,preoperative Glasgow Coma Scale (GCS) score,pupils,preoperative systolic pressure,application of mannitol,hyperventilation,methods for induction of anesthesia,and decrease in intracranial pressure were recorded.The risk factors of which P values were less than 0.05 would enter the multi-factor logistic regression analysis to stratify the independent risk factors for intraoperative hypotension.Results Fifty patients developed intraoperative hypotension,and the incidence was 28.57％.There was significant difference in preoperative systolic pressure,GCS score and changes in pupils between hypotension group and non-hypotension group (P ＜ 0.05).Logistic regression analysis showed that preoperative systolic pressure was the independent risk factor for hypotension during craniotomy in patients with severe TBI (P ＜ 0.05),and OR value (95％ confidence interval) was 1.019 (1.005-1.033),and regression coefficient was 0.019.Conclusion Preoperative systolic pressure is the independent risk factor for hypotension during craniotomy in patients with severe TBI.

Objective To investigate the concentration change of indoxyl sulfate (IS) in blood and the renal expression of renal fibrosis-related factors (transforming growth factor-beta 1, TGF-β1;fibronectin, FN) after administration of mutagenic lactobacilli by oral.Methods A total of 60 male Sprague-Dawley (SD) rats aged 6 weeks was divided randomly into 3 groups.The normal control group (Sham group, n =20) received Sham operation of just incision of skin without kidney removed.The other two groups of rats were renal failure models selected from survivals of the other 40 rats who received real operation with 5/6 of kidney removed.Finally, 35 survived renal-failure rats were divided randomly into 2 groups : pathological control group(Model group, n =17) who were administrated of 2ml sterile saline solution once a day by gavage, and experimental group (lactobacillus bulgaricus (LB) group, n =18) who were administrated of 2 ml mutagenic lactobacilli (1.5 × 108 cfu/ml) once a day by gavage.Eight weeks later, blood specimens were taken to test the concentration of IS with high performance liquid chromatography-fluorescence detection (HPLC-FLU), and urea and creatinine by automatic biochemical analyzer;moreover, the rats were killed to get kidney tissues for pathological examination.Results The levels of serum IS, urea, and creatinine were statistically significantly different between two groups (P ＜ 0.05).Both the levels of renal tubular damage and renal interstitial fibrosis were both lessen in the experimental group compared to the model group (P ＜0.05).TGF-β1 and FN expressions in renal tissues were significantly decreased (P ＜0.05).Conclusions Mutagenic lactobacilli not only reduces serum concentration of IS, urea and creatinine in renal failure rats but lowers the expressions of TGF-β1 and FN in renal tissues.

Objective:To evaluate the clinical efficacy of tendon-regulating manipulation plus kinesiotherapy in treating low back pain. Methods:Sixty patients were randomized into a treatment group and a control group by using the random number table, 30 cases in each group. The treatment group was intervened by tendon-regulating manipulation plus kinesiotherapy, while the control group was by the tendon-regulating manipulation alone. The lumbar lordosis was measured by X-ray (side view), the pain was evaluated by analgesy meter, the lumbar range of motion was by using goniometer, and the function was judged by Oswestry disability index (ODI) before and after treatment, and the therapeutic efficacy was also observed. Results:After treatment, the pain level was significantly reduced, lumbar lordosis was significantly increased, the lumbar range of motion was markedly improved, and the ODI score significantly dropped (allP<0.05) in both groups; the improvement of each item in the treatment group was more significant than that in the control group (allP<0.05). The total effective rate was 90.0% in the treatment group versus 63.3% in the control group, and the difference was statistically significant (P<0.05). Conclusion:In the treatment of low back pain, tendon-regulating manipulation plus kinesiotherapy can mitigate topical pain, improve the motion of low back, enhance the quality of life, and produce a more significant therapeutic efficacy compared to tendon-regulating manipulation alone.

To reveal the innate immunity of mast cells against recombinant VP1-VP4 protein of foot-and-mouth disease virus (FMDV), mouse peritoneal mast cells (PMCs) were pulsed with recombinant VP1-VP4 protein. The supernatants harvested from PMCs cultures were applied to the high throughput ELISA array. Our results show that the expression levels of CCL19, L-selectin, CCL17, and TNF alpha released from PMCs pulsed with recombinant VP1-VP4 were significantly down-regulated compared with PMCs alone (P<0.001). Surprisingly, in comparison with PMCs alone, the expression levels of CCL19, IL-15, IL-9, G-CSF, and Galectin-1 in PMCs with the mannose receptor (MR) inhibitor were significantly up-regulated (Plt;0.01), and the expression level of IL-10 was also remarkably up-regulated (Plt;0.05). Importantly, the protein expression levels in PMCs treated with MR inhibitor were higher than PMCs pulsed with VP1-VP4, including IL-10, IL-17, CCL20, IL-15, IL-9, L-selectin, CCL17, TNF alpha, and CCL19 (Plt;0.01) as well as CCL21, and G-CSF (Plt;0.05). Differential expression analysis in bioinformatics shows that both L-selectin and CCL17 were recognized as differentially expressed protein molecules (Log2(ratio)≤-1) when compared with PMCs alone. Furthermore, the up-regulation of the expression levels of CCL20, CCL19, L-selectin, and IL-15 in PMCs treated with MR inhibitor was defined as differential expression (Log2(ratio)≥1). These data indicate that PMCs are capable of secreting CCL19, L-selectin, CCL17, and TNF alpha spontaneously and the recombinant VP1-VP4 has an inhibitive potential to PMCs during their performance of innate immune response. Given the protein expression levels from PMCs pre-treated with MR inhibitor were significantly increased, it can be deduced that immunosuppression of FMDV is presumably initiated by the VP1 recognition of MR on mast cells.

Objective: Positron emission tomography-computed tomography (PET-CT) has been used to quantify inflammatory response in the body. The aim of the present study was to explore the possibility of using this method to evaluate the stability of atherosclerotic plaques and the efficacy of atorvastatin in stabilizing atherosclerotic plaques. Methods: Twenty New Zealand male white rabbits were included and divided into the atorvastatin intervention group and the control group, with 10 rabbits in each group. Rabbits in both groups were fed with a high fat diet for 20 weeks, and treated with thoracoabdominal aortic balloon-pulling to establish atherosclerosis model at the end of the 2nd week. Rabbits in atorvastatin intervention group was given atorvastatin intragastrically once a day. At the 8th week, thoracoabdominal aortic ultrasound was used to detect plaques in all rabbits. Blood was drawn at the 3rd and the 20th week, respectively, to measure blood lipids, high-sensitive C-reactive protein (hs-CRP) and matrix metalloproteinase-9 (MMP-9). At the end of experiment, survival animals were scanned by ¹⁸F-FDG PET-CT, and the average and maximum standard uptake values (SUVmean, SUVmax) of aortic segments were measured. Thereafter, the animals were sacrificed and aortic specimens of rabbits were taken and examined by immunohistochemistry. The pathological indexes were measured and compared. Results: At the end of experiment, the total cholesterol (TC), triglyceride (TG), low-density lipoprotein cholesterol (LDL-C), hs-CRP [ (4.58±0.51) ng/ml vs.(5.87±0.66) ng/ml, P<0.01], MMP-9[ (43.93±2.16) ng/ml vs. (50.77±2.32) ng/ml, P<0.01], SUVmean (0.59±0.15 vs. 0.68±0.20, P<0.05) , SUVmax (0.68±0.20 vs. 0.81±0.27, P<0.05) , plaque area [ (0.36±0.24) mm² vs. (0.50±0.34) mm², P<0.05) ] and density of macrophage[ (4.34±1.54) % vs. (5.65±1.89) %, P<0.01] in the atorvastatin intervention group were significantly lower than those in the control group. In contrast, fiber cap thickness of the plaque[ (4.12±0.66) μm vs. (2.96±0.37) μm, P<0.01] in the atorvastatin intervention group was higher than that of the control group, and the difference was statistically significant. The arterial plaque areas were positively correlated with SUVmean (r=0.27, P<0.05) and SUVmax (r=0.43, P<0.01) . Fiber cap thickness was negatively correlated with SUVmean (r=-0.38, P<0.05) and SUVmax (r=-0.47, P<0.01) . The density of macrophage were positively correlated with SUVmean (r=0.52, P<0.01) and SUVmax (r=0.51, P<0.01) . Conclusion ¹⁸F-FDG PET/CT can be used to evaluate the efficacy of atorvastatin by the stability of atherosclerotic plaques.
