METHODS： Five groups were allocated （n = 8） in the study. Group Ⅰ was taken as the control group, group Ⅱ as the hemorrhagic shock group, group Ⅲ as hemorrhagic shock ＋ laparotomy, group Ⅳ as hemorrhagic shock ＋ splenectomy and group V as splenectomy ＋ omentectomy ＋ hemorrhagic shock group. Hemorrhagic shock was induced by drawing blood and reducing mean arterial pressure （MAP） to 40 mmHg within 10 min. After a hypotensive period of 1 h, animals were resuscitated. Bronchoalveolar lavage （BAL） was performed to recover cells from the alveolar space with 40 mL of BAL fluid after resuscitation malondialdehyde （MDA） and L-γ-glutamyl-L-cysteinylglycine （GSH） levels were measured in serum, erythrocytes and lung tissue. RESULTS： Serum, erythrocyte, lung tissue MDA and GSH levels were significantly increased in hemorrhagic shock groups Ⅱ-Ⅴ （P 〈 0.05）. Lymphocyte, neutrophil and alveolar macrophage counts in BAL fluid indicated a significant difference between control and shock groups （P 〈 0.05）. CONCLUSION： The degree of trauma increases hemorrhagic shock-induced acute lung injury.展开更多

Methods: Forty-four patients complication with acute lung injury after abdominal operation were analyze with multiple clinical and laboratory parameters and were treated early with herbs activating blood circulation and dispersing stasis. Results: After 2 days of medication,arterial oxygen saturation (SaO2 ) and partial pressure of oxygen in artery (PaO2 ) markedly improved, with significant difference as compared with those before medication (P < 0. 01 ). After continous medication for 4 days, SaO2, PaO2 and chest X-ray as well as synthetic physiologic parameters obviously improved, prostaglandin F1a,thromboxane B2 (TXB2 ), C-reactive protein (CRP), erythrocyte C3b were very significantly different from those medication (P < 0. 01 ), the synthetic physiological parameters returned generally to normal. After 5 days of herbal medication, all parameters resumed normal with satisfactory physiologic criteria. Conclusions: Early application of herbs activating blood circulation and dispersing stasis could obviously improve hypoxemia and the lung lesions, and consequently the general condition of the patient.展开更多
