Methods: Thirty-eight patients scheduled for lower extremity surgery were randomized into three groups using the closed envelop method: Shenmai Injection was administered 30 min before tourniquet inflation by nebulization [0.6 mL/kg in 10 mL normal saline (NS)] in the nebulization group or by intravenous drip (0.6 mL/kg dissolved in 250 mL of 10% glucose) in the intravenous drip group, and equal volume of NS was given intravenously in the NS group; 15 in each group. Arterial blood gases were analyzed, serum levels of malonaldehyde (MDA) and interleukine-6 (IL-6) and interleukine-8 (IL-8) were determined using the method of thiobarbituric acid reaction and enzyme-linked immuno sorbent assay respectively just before tourniquet inflation (TO), and at 0.5 h (T1), 2 h (TZ), 6 h (T3) after tourniquet deflation. Results: Compared with baselines at TO, MDA levels significantly increased at TZ, T3 in the NS group and at T3 in the nebulization group, and IL-6 and IL-8 levels were significantly increased at TZ, T3 in NS, the intravenous drip and the nebulization groups (P〈0.05). Arterial pressure of oxygen (PaO2) at T3 was decreased, while alveolar- arterial oxygen tension showed difference (PA-aDO2) at T3 in the NS group; RI at T3 in both intravenous drip and the nebulization groups were enhanced (P〈0.05). Compared with the NS group, MDA and IL-8 levels at TZ, T3, 11-6 at T3 in the intravenous drip group, and IL-8 at T3 in the nebulization group were all remarkably increased (P〈0.05). Additionally, MDA level at T3 in the nebulization group was higher than that in the intravenous drip group (P〈0.05). Conclusions: Intravenous administration of Shenmai Injection provided a better protective effect than nebulization in m展开更多

Our study aimed to explore the dynamic changes of AQP1 in pulmonary water metabolism in rats following traumatic brain injury (TBI) and the protective effect provided by shenmai injection.Methods Sixty male Sprague Dawley rats weighting 280-300 g were randomly divided into three groups: the normal control group, the model group and the shenrnai injection (SMI) group. One piece skull was taken away without injuring cerebral tissue in normal control group, while rats in model group and SMI group were subject to free fall injury in the cerebral hemisphere. Rats in model group received intraperitoneal normal sodium (15 mi/kg) at one hour post-injury and the same dose of shenmai injection instead in SMI group, respectively. The expression of AQP1 was detected by immunohistochemical analysis and semi-quantitative RT-PCR at 0 hour, 10 hours, 72 hours and 120 hours after TBI.Arterial blood gas analysis and lung wet to dry were also measured.Results AQP1 was mainly presented in the capillary endothelium and slightly alveolar epithelial cells in three groups, but the expression of AQP1 in the normal control group was positive and tenuous, weakly positive in the model and SMI groups,respectively. Compared with normal control group, AQP1 mRNA levels were down regulated in the model and SMI groups at 10 hours, 72 hours and 120 hours (P £1/40.05). While AQP1 mRNA levels in the SMI group was up-regulated than that in the model group (P£1/40.05). Lung wet to dry weight ratio (W/D) in the model and SMI groups at 10 hours were higher than that in normal control group (P £1/40.05). Compared with normal control group, PaO2 was markedly lower in the model and SMI groups (P £1/40.05), but there were no statistically significant differences between model and SMI groups (P £3/40.05).Conclusions The decreased AQP1 expression may be involved in the increased lung water content and dysfuncti展开更多

Methods: The HASMCs cultured in vitro were divided into three groups: (1) control group; (2) sensitized group: containing 10% asthmatic serum; (3) SMI group: further divided into three different concentration subgroups interferred with 10 μL/mL, 50 μL/mL, and 100 μL/mL SMI, respectively. The proliferation of HASMCs was detected using MTT method, the expression of proliferating cell nucleus antigen (PCNA) in HASMCs was detected using immunocytochemical staining, and the expression of phosphoration-ERK1/2 (p-ERK1/2) protein was detected using Western-blot. Results: After passive sensitization, the optical density value (A49o value) of HASMCs was significantly increased from 0.366± 0.086 to 0.839 ± 0.168 (P〈0.05). In addition, the expression of PCNA was significantly increased from 28.7% ± 5.9% in the control group to 69.8% ±7.5% in the sensitized group (P〈0.05). At the same time, the expression of p-ERK1/2 in passively sensitized HASMCs was significantly increased compared with the control group (all P〈0.05). Affer application of 10 μL/mL, 50 μL/mL, and 100 μL/mL SMI to the cultured media of passively sensitized group, the A570 value was significantly decreased from 0.839 ±0.168 to 0.612 ±0.100, 0.412 ± 0.092, and 0.339 ± 0.077, respectively (P〈0.05). Moreover, the expression of PCNA was significantly decreased from 69.8% ±7.5% to 57.8% ± 6.2%, 40.7%±5.4%, and 26.1% ± 5.2%, respectively. At the same time, the expression of p-ERK1/2 in each SMI group was significantly decreased compared with the sensitized group (all ,P〈0.05). Conclusion: ERK signal transduction pathway may be involved in the airway remodeling in asthma. The expression of ERK can be inhibited by S展开更多
