OBJECTIVETo explore the effect of Tanshinone II A on severe acute pancreatitis (SAP) lung injury (ALI) rats and its possible mechanism.

METHODSSD rats were injected with sodium taurocholate to induce SAP group, and then intervened with sodium tanshinone II A sulfonate ( STS group). Simultaneously a sham-operation group (SO group) was set up. There were 24 rats in each group. The survival state and wet-to-dry weight ratio of lung tissues were observed. Activities of myeloperoxidase (MPO) in lung were determined by MPO reagent kit. Pathologic changes of lung tissues were determined by Hofbuaer method. Expression levels of three cytokines, TNF-alpha, IL-1beta, and intercellular cell adhesion molecule-1 (ICAM-1) were detected by ELISA.

RESULTSThe survival state of rats in the SAP group was deteriorated. The wet-to-dry weight ratio, MPO activities, pathologic changes in lung tissues, and expression levels of TNF-alpha, IL-1beta, and ICAM-1 increased significantly more in the SAP group than in the SO group (P < 0.05). Compared with those in the SAP group, the survival state of rats in the STS group was improved; the wet-to-dry weight ratio, MPO activities, pathologic changes in lung tissues, and expression levels of TNF-alpha, IL-1beta, and ICAM-1 obviously decreased in the STS group (P < 0.05).

CONCLUSIONTanshinone II A had remarkable effect on SPA LI rats, which might be associated with changing cytokines levels and attenuating infiltration of lung inflammatory cells.

BACKGROUND:Skin and soft tissue defects of hands are easy to appear due to different factors, such as trauma. Flap transplantation is a clinical treatment for soft tissue defects of hands. Dorsal foot flap, which is thicker with constant vessel traveling, is very suitable for repair of hand soft tissue defects. OBJECTIVE: To explore the success rate and survival rate of dorsal foot flap transplantation in the repair of hand skin and soft tissue defects. METHODS: A retrospective analysis was performed on the clinical data of 86 patients with skin and soft tissue defect of hands. These patients were respectively given conventional skin wound skin grafting (control group) and dorsal foot flap transplantation (observational group). Hand appearance, infection rate, perception recovery and complications were observed during the postoperative folow-up. RESULTS AND CONCLUSION:Skin flaps al survived after grafting, and the texture of flaps was good. Patients were satisfied with hand shape and the recovery of hand function. After flap transplantation, one patient had local skin necrosis at the donor region, and the scar healed after dressing; another patient had venous crisis, and was given vascular re-anastomosis. In the observation group, the postoperative appearance was better than that of the control group, the infection rate was lower than that of the control group, the perception recovery was better, and there were fewer complications (P < 0.05). These findings suggest that the dorsal foot flap transplantation is better to repair skin and soft tissue defects in the hand.

BACKGROUND:Metabolic syndrome greatly harms the human body, and is affected by many factors. Through constructing diet-induced animal models, we can better analyze the relationship between nutritional factor and metabolic syndrome, and provide reliable references for the clinical treatment of this disorder. OBJECTIVE:To construct obese mouse models with high-fat diet feeding and discuss the relationship between nutritional factor and metabolic syndrome. METHODS:Thirty mice were selected and randomly divided into model group (n=20) and control group (n=10), and were fed with high-fat and normal animal feeds for 10 consecutive weeks. RESULTS AND CONCLUSION:Compared with the control group, after 1 week of feeding with high-fat animal feeds, body weight of mice in the model group raised, and differences gradualy increased with the feeding time increased. After 8 weeks of feeding, body mass index of mice in the model group significantly raised (P < 0.05). After 4 weeks of feeding, fasting venous blood glucose level of mice in the model group significantly raised, and showed a gradual rise trend with feeding time. After 5 weeks of feeding, fasting insulin level of mice in the model group also began to rise. The oral glucose tolerance test showed that mice in the model group showed a gradual downward trend of glucose tolerance with feeding time. After 8 weeks of feeding, serum levels of total cholesterol and high density lipoprotein cholesterol in the model group significantly raised (P < 0.05). After 10 weeks of feeding, serum levels of triacylglycerol, total cholesterol, low density lipoprotein cholesterol and high density lipoprotein cholesterol in the model group raised (P< 0.05). The results demonstrate that obese mouse models were successfuly constructed with high-fat diet feeding, which can simulate the natural progression of metabolic syndrome in human, moreover, the nutritional factor is closely related to metabolic syndrome.

Objective Pulmonary fibrosis ( PF) is a group of pulmonary interstitial pathological changes caused by various factors, and its pathogenesis is not yet fully elucidated .This article discussed the effect of lycium barbarum polysaccharide ( LBP) on ble-omycin-induced PF in mice and its action mechanisms . Methods The C57/BL6 mice were randomly divided into 6 groups:sham-opera-tion, PF model, dexamethasone ( DM), high-dose LBP, medium-dose LBP, and low-dose LBP.The mice in the sham-operation group were injected into the trachea with isotonic saline and those in the oth-er groups with 5 bleomycin at mg/kg for establishing the PF model . Two days after modeling , the mice in the DM and high-, medium-,and low-dose LBP groups were treated with DM at 5 mg/kg and LBP at 0.8, 0.4, and 0.2 g/kg, while those in the sham-operation and PF model groups with the same volume of isotonic saline , respectively , qd, for 4 consecutive weeks .Then, the pathological chan-ges of the lung tissue were observed and the hydroxyproline ( HYP) content in the lung tissue was detected for all the animals .RT-PCR was used to determine the relative expressions of the PF-related COL1A1 and α-SMA genes. Results Compared with the PF mod-els, the the high-, medium-, and low-dose LBP groups showed significant increased body weight after 4 weeks of medication ([14.29 ±0.38] vs [16.12 ±0.37], [15.58 ±0.25] and [15.07 ±0.21] g, P<0.01), the high-and medium-dose groups ex-hibited remarkably decreased lung indexes ([0.887 ±0.13] vs [0.847 ±0.22] and [0.859 ±0.18]%, P<0.05), and the high-dose group presented markedly reduced alveolitis score (3.40 ±0.23 vs 3.09 ±0.22, P<0.05), PF score (3.57 ±0.27 vs 3.07 ± 0.31, P<0.01) and HYP content ([0.831 ±0.05] vs [0.786 ±0.07] μg/mg wet weight, P<0.05).In comparison with the mod-el group, the DM, high-dose LBP and medium-dose LBP groups showed significantly decreased gene expressions of COL 1A1 (1.53 ± 0.13 vs 1.26 ±0.10 and 0.98 ±0.17, P<0.05) and α-SMA (5.67 ±0.47 vs 4.19 ±0.28 and 2.29 ±0.31, P<0.05). Conclusion LBP can suppress the progression of bleomycin-induced pulmonary fibrosis by inhibiting the gene expressions of COL 1A1 andα-SMA and decreasing the HYP content in the lung tissue .
