Objective To discuss the value of emergency bedside ultrasound in diagnose of blunt abdominal injury. Methods Portable ultrasound was used in 184 patients with blunt abdominal trauma in emergency department. The abnormal changes of the sound and image of the abdomen were observed,paying equal attention to free intraperitoneal fluid and gas. Results The emergency bedside ultrasound identified 169 (91.8%) patients with blunt abdominal injury, of whom 149 patients (95.5%) with single-organ injury and 20 patients (71.4%) with multi-organ injury. There were 21 patients missed diagnosis and three misdiagnosed, with rate of missed diagnosis and misdiagnosis of 13%. Surgical treatment was performed in 119 patients and conservative treatment in 65, which were proved by CT/MRI examination or clinic conservative treatment. Conclusion Emergency bedside ultrasound can provide fast and credible diagnostic information for blunt abdominal trauma, with high diagnosis accordance rate.

p53 gene mutation (exon4 , 5 , 6 . 7 . 8 and intron6) in gastric cancer and precancerous le- sions and p53 gene (exon4 and intron6) .APC gene deletion in gastric carcinomas were studied by PCR/ SSCP and PCR/RFLP. Results showed: mutation rate of p53 in intestinal metaplasia ,dysplasia and gas- tric carcinoma was 37. 5% (3/8) ,42. 1 % (8/19) , 53. 3% (16/30) ,respectively. There was significant dif- ference between groups of metaplasia、dysplasia、cancer and that of normal control. We found there were no exon8 mutation in metaplasia and dysplasia , but 4 cases in cancer group. lt is suggestted that exon8 mutation occurs at the late stage of gastric cancer , but exon 5 , 6 , 7 mutation occur in the course of pre- cancerous lesions to cancer. Loss of heterozygosity (LOH) of exon4 . intron6 . APC was 47. 4 % ( 9/19) . 8. 7%C2/23).16. 7%(3/18) ,respectively. There are some relationship between LOH of exon4 and poor- ly differentiation , lymph node metastas , depth of invasion. LOH of exon4 may be one of prognostic marker of gastric cancer. We concluded that p53 gene mutation is an early event and perhaps has syner- gism with ras oncogene in gastric carcinogenesis

ObjectiveTo evaluate the clinical efficacy and safety of astragalus injection on the immune function in patients with senile sepsis.Methods Sixty patients with old age sepsis in Critical Care Medicine Department of Guangdong Provincial Traditional Chinese Medicine Hospital were enrolled and randomly assigned into control and treatment groups according to the table of random numbers, 30 cases in each group. According to 2012 sepsis guidelines for treatment, including antibacterial drug, mechanical ventilation, visceral function support, etc., the therapy was given to the control group; besides the treatment in the control group, intravenous drip of 60 mL astragalus injection(10 mL per ampoule) in 250 mL 0.9% normal saline was additionally given in the treatment group, once a day for 7 days. Before and after treatment, the immunological indexes, acute physiology and chronic health evaluationⅡ(APACHEⅡ) score, sequential organ failure assessment(SOFA) score, duration of mechanical ventilation and time of stay in intensive care unit(ICU), 28-day mortality and adverse drug reactions were compared between the two groups.Results Before treatment, there were no statistically significant differences in CD3+, CD3+CD4+, CD3+CD8+ and T helper cells /T suppressor cells(Th/Ts)levels between the two groups(allP>0.05), while CD3-NK+ of the control group was significantly higher than that in the treatment group〔(10.47±6.22)% vs. (6.26±4.13)%,P<0.05〕. After treatment in treatment group, CD3+, CD3+CD4+ and CD3-NK+ were increased, CD3+CD8+,Th/Ts were decreased compared with those before treatment; in the control group after treatment, CD3+,CD3+CD8+ and CD3-NK+ were decreased and CD3+CD4+ and Th/Ts increased compared with those before treatment. In the comparisons between the treatment group and control group after treatment, the differences in CD3+, CD3+CD4+ and CD3+CD8+ had statistical significance〔CD3+:(30.30±17.17)% vs.(41.91±22.29)%, CD3+CD4+:(31.54±13.24)% vs.(40.08±15.28)%, CD3+CD8+:(14.25±8.10)% vs.(9.52±9.33)%,allP<0.05〕; while the differences in Th/Ts and CD3-NK+ had no statistical significance(bothP>0.05). After treatment in the treatment group, IgG was increased compared with that in the control group〔IgG(g/L): 13.07±5.43 vs. 10.10±3.96,P<
0.05〕. The differences in IgA, IgM, complement(C3,C4) and total serum complement activity(CH50) in the comparisons between the two groups had no statistical significance after treatment(allP>0.05). The differences in APACHEⅡ score(13.83±6.18 vs. 15.90±7.48), SOFA score(7.38±4.66 vs. 6.89±4.19), time of stay in ICU(day: 11.63±5.13 vs. 13.62±8.08), invasive ventilation time(hour: 155.44±119.68 vs. 224.08±174.15) and noninvasive ventilation time(hour: 55.55±42.24 vs. 98.57±43.17) had no statistical significance in comparisons between the treatment group and control group after treatment(allP>0.05). The difference in 28-day mortality had no statistical significance in comparison between the treatment group and control group〔16.7%(5/30) vs. 20.0%(6/30),P>0.05〕. In 60 cases, there were 2 patients with adverse drug reaction, one diarrhea and another little rashes, the rest of the patients did not appear any drug side effect.ConclusionAstragalus injection combined with conventional western medicine therapy possibly has certain effect on adjustment of disturbance of immunologic functions in old patients with sepsis, and its therapeutic safety is well.

Objective To determine the contributions of main chemical compositions of extracts of Eucalyptus camaldulensis represented by GC/MS elute peaks to the molluscicidal activities,and explore a shortcut of looking for the effective components from natural products. Methods E. camaldulensis leaves were collected consecutively in 12 months at the same place,extracted with dichloromethane,analyzed by GC/MS,and their LC50(s)of molluscicidal activities were tested according to the method rec-ommended by WHO. The correlation of the main components in 12 extracts and their molluscicidal activities were analyzed by the grey relative correlation analysis model with software GTMS 3.0. Result All the dichloromethane extracts of eucalyptus leaves showed excellent molluscicidal activities with the highest LC50 of 0.257mg/L and 0.242mg/L for the samples in June and July and the lowest LC50 of 6.802 mg/L and 5.406 mg/L in December and January respectively. The structures of 16 main chemical compo-nents were elucidated by GC/MS and NIST Mass Spectral Library,most of which were monoterpenes and sesquiterpenoids. The gray correlation coefficients with activity were all over 0.5,the first five over 0.9 were 4,4,8-Trimethyltricyclo[6.3.1.0(1,5)]do-decane-2,9-diol,(-)-Spathulenol,a structural isomer of(-)-Spathulenol,Eucalyptol and Ledol. Conclusion The most main in-gredients in the dichloromethane extracts of E. camaldulensis leaves show good correlations with the molluscicidal activity,which suggests that the molluscicidal role is synergistically played by the multiple components together.

Objective To evaluate the role of nuclear factor kappa B (NF-κB) in sevofluraneinduced release of inflammatory factors in mouse microglias.Methods Microglial cells obtained from newborn C57BL/6 mice (aged 2-3 days) were seeded in 24-well plates (density 1 × 105 cells/ml, 1 ml/well) , a total of 80 wells.The cells were randomly divided into 4 groups using a random number table (n =20 each) : control group (group C);sevoflurane group (group S);NF-κB selective inhibitor pyrrolidine dithiocarbamate (PDTC) group (group P);PDTC + sevoflurane group (group P +S).In S and P+S groups, 4.1％ sevoflurane was inhaled for 6 h.In P+S group, 10 μmol/L PDTC was added at 1 h before sevoflurane inhalation.At 6 h of incubation with sevoflurane, NF-κB activity and expression and levels of interleukin-6 (IL-6) and tumor necrosis factor-alpha (TNF-α) were determined.Results Compared with group C, the NF-κB activity and levels of IL-6 and TNF-α were significantly increased in group S, and no significant change in the above parameters was found in the other two groups.Compared with group S, the NF-κB activity and levels of IL-6 and TNF-α were significantly decreased in group P+S.There was no significant difference in NF-κB expression between the four groups.Conclusion NF-κB mediates sevoflurane-induced release of inflammatory factors in mouse microglias.
