Objective To observe the curative effect of continuous gastrointestinal decompression after gastric lavage with edible oil on saving patients with oral aluminum phosphide poisoning.Methods Seventy-eight patients with oral aluminum phosphide admitted to the Department of Internal Emergency of the Second People's Hospital of Yunnan Province from October 2009 to October 2016 were divided into a mild poisoning group (39 cases), a moderate poisoning group (26 cases) and a severe poisoning group (13 cases) according to clinical manifestations and laboratory examinations, all the patients were treated with continuous gastrointestinal decompression after early gastric lavage with edible oil, including scavenging toxicant, correcting intracellular oxygen intake and metabolic disturbance, and inhibiting and eliminating inflammatory mediators. The difference of remission times of clinical symptoms, recovery times of abnormal indexes and hospitalization times were compared among patients with different disease severities. Results With the aggravation of disease, the remission times of clinical symptoms (hours: from mild to severe were 24±12, 54±18, 84±12), recovery times of abnormal indexes (hours: from mild to severe were 18±6, 72±0, 108±12) and hospitalization times (hours: from mild to severe 48±24, 120±24, 144±24) were all gradually extended. Of the 13 patients with severe poisoning, 2 patients died of multiple organ functional failure (MOF) after 28 hours of treatment because they were incapable of cooperating with continuous gastrointestinal decompression. There were 76 patients were clinically cured, the cure rate being 97.4%. In the follow-ups at 1 month and 6 months after the treatment, no abnormalities were seen.Conclusion Continuous gastrointestinal decompression after early gastric lavage with edible oil for saving patients with oral aluminum phosphide poisoning is an effective therapy worthwhile to be popularized.

Objective Recent studies have indicated that early brain injury is the leading cause of death in patients with subarachnoid hemorrhage ( SAH) .Our study investigated the role of aminoguanidine ( AG) in early brain injury after SAH . Methods Sixty-eight male SD rats were equally randomized into four groups of equal number :control, sham, SAH, and AG.The animals in the sham group were injected with isotonic saline solution , while those of the latter two groups with femoral artery blood ( FAB) and FAB+AG, respectively, into the pre-chiasmatic cistern to induce SAH. At 24 hours after modeling , all the rats were killed for HE staining , obtainment of behavioral neurological assessment ( BNA ) scores by Garcia, measurement of the apoptosis of neurons by TUNEL , and de-termination of the expressions of the iNOS and NSE proteins by West-ern blot. Results The results of HE staining showed the presence of more red blood cells in the subarachnoid cavity of the rats in the SAH group, with a significantly decreased BNA score ( 14.47 ± 0.62) as compared with those in the control (17.94 ±0.24), sham (17.59 ±0.51), and AG group (15.71 ±0.47) (P<0.05). The rate of positive cells was remarkably higher in the SAH group ([42.38 ±2.38]%) than in the control ([6.35 ±0.94]%), sham ([6.85 ±0.69]%), and AG group ([30.48 ±2.89]%) ( P<0.01), with significant differences among the latter three groups (P<0.05).The expressions of iNOS and NSE were markedly higher in the SAH group ([3.86 ±0.07] and [1.59 ±0.06]) than in the control (0 and[0.35 ±0.09]), sham ([2.96 ±0.34] and [0.38 ±0.08]), and AG group ([3.41 ±0.04] and [0.70 ±0.12]) ( P<0.05).Both the expression levels of iNOS and NSE were positively correlated with the rate of positive cells (r=0 .879 and 0.935, P<0.01). Conclusion AG can alleviate early brain injury after SAH in SD rats by improving the neuro-ethologic function , suppressing the apoptosis of neurons , and reducing the expressions of iNOS and NSE .

Objective To explore the mechanism underlying the protective effect of α2-macroglobulin (A2M) against glucocorticoid-induced femoral head necrosis. Methods In a human umbilical vein endothelial cell (HUVEC) model with injuries induced by gradient concentrations of dexamethasone (DEX;10-8-10-5 mol/L), the protective effects of A2M at 0.05 and 0.1 mg/mL were assessed by examining the changes in cell viability, migration, and capacity of angiogenesis using CCK-8 assay, Transwell and scratch healing assays and angiogenesis assay. The expressions of CD31 and VEGF-A proteins in the treated cells were detected using Western blotting. In BALB/c mouse models of avascular necrosis of the femoral head induced by intramuscular injections of methylprednisolone, the effects of intervention with A2M on femoral trabecular structure, histopathological characteristics, and CD31 expression were examined with Micro-CT, HE staining and immunohistochemical staining. Results In cultured HUVECs, DEX treatment significantly reduced cell viability, migration and angiogenic ability in a concentration- and time-dependent manner (P<0.05), and these changes were obviously reversed by treatment with A2M in positive correlation with A2M concentration (P<0.05). DEX significantly reduced the expression of CD31 and VEGF-A proteins in HUVECs, while treatment with A2M restored CD31 and VEGF-A expressions in the cells (P<0.05). The mouse models of femoral head necrosis showed obvious trabecular damages in the femoral head, where a large number of empty lacunae and hypertrophic fat cells could be seen and CD31 expression was significantly decreased (P<0.05). A2M treatment of the mouse models significantly improved trabecular damages, maintained normal bone tissue structures, and increased CD31 expression in the femoral head (P<0.05). Conclusion A2M promotes proliferation, migration, and angiogenesis of DEX-treated HUVECs and alleviates methylprednisolone-induced femoral head necrosis by improving microcirculation damages and maintaining microcirculation stability in the femoral head.
