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 To explore the prophylaxis and treatment strategies for psychic syndrome in patients after piggyback liver transplantation.Methods The data on the etiology,treatment outcome and prognosis of psychic syndrome occurring in 45 of 235 patients who had piggyback liver transplantation were retrospectively analyzed.Results The incidence of psychic syndrome complication was 19.1%(45/235),22 cases presented as mania(48.9%),5 cases as tristimania(11.1%),3 cases as hallucinosis(6.7%),1 case as suicidal tendency(2.2%),1 case as metamorphopsia(2.2%),8 cases as angst insomnia(17.8%),2 cases as maladjusted disturbance(4.4%),3 cases as affective disturbance(6.7%),and the majority presented as delirious alienation.All the cases were cured,except 1 case of coma,who was confirmed by CT to have intracranial hemorrage,died after failure of resuscitation.Conclusions The incidence of psychic syndrome in patients after piggyback liver transplantation is relatively high.However,most cases have mild symptoms and the prognosis is fine.When the patients have psychogenic symptoms,the prognosis of patients can be improved by some symptomatic treatment strategies directed to their different clinical manifestations.

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 develop a novel screening reagent for -D- phenotype preliminary screening based on the difference in RhD antigen expression level of -D- phenotype and normal RhD phenotype. 【Methods】 RhD antigen expression of -D-phenotype and Rh D-- gene carrier were detected by flow cytometry. By adjusting the concentration of polybrene in the screening system, the red blood cells with high RhD antigen expression level agglutinated, and the preliminary screening of the -D-phenotype and its gene carriers was realized. 【Results】 According to the quantitative results of immunofluorescence intensity (MFI) analysis by flow cytometry, the expression level of RhD antigen in -D- phenotype cells (284 360±16 698, n=3) was about 3 times normal RhD positive cells (98 642±35 908, n=9)(P<0.01), while RhD antigen expression level of RhD-- gene carrier (181 109±39 455, n=4) was about 2 times normal RhD positive cells(P<0.01). RhD antigen expression (144 538±227 445, n=7) of the positive cells screened by 15 μL 3% fresh red blood cell suspension and screening system 35 μL (1 μL IgG anti-D, 29 μL polybrene polybrene, and 5 μL low ionic strength solution) was about 1.5 times normal RhD positive cells. 【Conclusion】 The polybrene preliminary screening system, which can be used for high-throughput screening of -D- phenotype, is a reliable technical method for frequency study of this phenotype.
