Objective To observe the recent clinical effects and toxicity in advanced gastric carcinoma by neo-adjuvant chemo-therapy FOLFOX and XELOX .Methods A total of 81 patients with Ⅱ ~ Ⅲ level of gastric cancer underwent neo-adjuvant chemo-therapy before curative resection were collected ,and divided into two groups ,as XELOX group(n=26) and FOLFOX group(n=25) .30 patients who just underwent surgical treatment did not received neo-adjuvant chemotherapy were taken into control group(n=30) .The curative resection rate and complications were compared in three groups .Results There were no obvious differences be-tween XELOX group and FOLFOX group in recent clinical effect (P>0 .05) ,but FOLFOX group had higher toxic reaction rate (P<0 .05) .The curative resection rates of XELOX group and FOLFOX group were higher than that of control group (P<0 .05) . The complication rates in three groups showed no significant difference (P>0 .05) .Conclusion Neo-adjuvant chemotherapy could increase the curative resection rate of advanced gastric cancer ,which does not increase the complications ,and the program XELOX had less toxic reaction .

Objective To explore the positive distribution characteristics and analyse the correlation of common food allergen-specific immunoglobulin E (sIgE) with suspected food allergy in the First Affiliated Hospital of Guangzhou Medical University.Methods Using fluorescence enzyme-linked immunosorbent assay to detect the serum sIgE antibody of 854 patients,including 7 kinds of food allergens (milk,egg white,egg yolk,shrimp,crab,peanut and soybean) from July 2006 to January 2013.Data were processed by statistical software SPSS19.0.Results The positive rates of the 7 kinds of food allergen were 39.3％ (283/720),36.3％ (216/595),9.8％ (28/285),21.2％ (36/170),24.3％ (17/70),14.8％ (9/61) and 10.0％ (5/50).Two hundred and eighty-two patients were detected egg white and egg yolk sIgE,the positive rate of egg white sIgE 59.6％ (168/282) was much higher than the egg yolk sIgE 9.2％ (26/282).The positive rate of the milk and egg white sIgE were different between the age groups and decreased with the age(milk:x2 =792.88;egg white:x2 =658.21,P ＜ 0.01).The degree in level 4 or above of milk and egg white sIgE were 1.08％ (2/186) and 1.12％ (2/178) in positive patients.Five hundred and twenty-eight patients were detected milk and egg white sIgE,26.9％ (142/528) were both positive,sIgE levels in serum of them was moderately correlated (rs =0.758,P ＜ 0.01).Serum sIgE of shrimp and crab was detected in 64 patients,16 cases was positive of the shrimp,17 cases of the crab was positive,both positive in 16 cases,sIgE levels in serum of them were highly correlated (rs =0.973,P ＜0.01).In the simultaneous detection of 34 patients' serum sIgE of peanut and soybean,peanut was positive in 4 cases,soybean was positive in 3 cases,both positive in 2 cases,sIgE levels in serum of them were highly correlated (rs =0.879,P ＜ 0.01).Conclusions Egg white is the major allergen of egg allergy.The correlations of shrimp and crab,peanut and soybean are extremely high,probably because of their homology; egg white and milk are not homologous food,but the levels of sIgE between them display a moderately correlation,indicating the existing of synergistic reaction.

Tumor genesis and development often result from deregulation of important biological pathways at the gene expression level. Although there has been much work focused on searching gene sets using gene expression data or other prior information, proper statistical testing of the gene sets is still an open question. Most studies have expanded the testing method of a single gene into the gene sets. Parametric statistical analysis of gene sets ( p-SAGE ) was presented for determining the significant gene sets or pathways associated with a phenotype of interest. The method was applied to brain tumor experiments to identify many gene sets. Some of the newly discovered gene sets were related to signal transduction and immunity. This simple and effective method gives useful biologically meaningful results.

【Objective】Finding the relative factors that influence the effect of electronic burn therapy in chronic cervicitis.【Methods】Some pathogens have been detected in 176 cases of patients with chronic cervicitis who have underwent electronic burn therapy.Some possible relative factors that influence the effect of electronic therapy in chronic cervicitis have been analysed.【Results】The relative factors include the degree of cervical erosion,character of cervical grume,degree of vaginal cleanness;puriform cervical grume,poor vaginal cleanness have higher positive rate of all kinds of pathogens.【Conclusion】Some relative pathogens should be detected and eliminated before electronic burn therapy in patients with chronic cervicitis.At least,those patients who present higher degree of cervical erosion,puriform cervical grume,poor vaginal cleanness should be treated with drug until these indexes improve before electronic burn therapy.

Objective To investigate the types and distributions of allergens, and the responsiveness to these allergens SIgE and tIgE as related to allergic disorders in patients with allergies in Guangdong. Methods Serum samples were obtained from patients with allergic disorders (n = 7 144) who visited our hospital between 2009 and 2014. The sera were subjected to analysis of 15 common allergens. Results The positive rates of sIgE and tIgE were 62.4%and 54.6%, respectively. Dermatophagoides pteronyssinus(Der p) had the highest prevalence of aeroallergen-specific IgE and milk the highest prevalence of food allergen-specific IgE. Other aeroallergens and food allergens produced mild responses except Der p and Der f. The sensitization peak of Der p and Der f appeared at the age of 10 to 12 years. The sensitization peak of milk appeared at the age of less than 3 years and that of eggs did at the aged of 4 to 6 years. The averaged tIgE positive rate went up with the increase in the number of allergen sensitization. Conclusion Der p, Der f, milk and eggs are major sensitizers responsible for common allergic disorders in Guangdong. Knowledge concerning allergen characteristics at various age groups may be helpful for early diagnosis and intervention for allergies.

Objective To investigate the role of molecular allergen diagnosis in respiratory allergic diseases, and measure the prevalence and the allergen molecular mapping of the asthma and allergic rhinitic patients.Methods Totally 80 cases of asthma or allergic rhinitis patients with two or more inhaled allergens from First Affiliated Hospital of Guangzhou Medical University during 2013 January to 2014 December were tested for serum specific immunoglobulin E ( sIgE ) against 112 allergen components by ImmunoCAP ISAC.Results About 78.8% ( 63/80 ) patients is three or more allergen components sensitization, the most prevalence allergen components were house dust mites′Der f 1 67.5%(54/80), Der f 2 66.2%(53/80), Der p 1 and Der p 2 were 63.8%(51/80) and 61.2%(49/80), Der p 10 was only 12.5%(10/80), follewed by Fel d 1 22.5%(18/80), Cyn d 1 16.2%(13/80), Phl p 4 15.0%(12/80), Pen m 1,Pla a 2,Jug r 2 and Can f 1were all 11.2%(9/80), Lep d 2, Blo t 5, Bla g 7 and Ani s 3 10.0%(8/80).Other allergen components positive rates were low.Conclusions Molecular allergen diagnosis can provide more comprehensive diagnostic information for allergic patients, by providing allergen map.Allergen microarray can discover the neglected allergens such as bermuda grass, timothy grass and plane tree pollen allergens in southen China.

Objective To systematically evaluate the effectiveness and safety of glucoside tripterygium total (GTT) combined with antihistamine medicine for chronic idiopathic urticaria (CIU). Methods All randomized or semi-randomized controlled trials (RCTs or semi-RCTs) of GTT in treating CIU were collected from CNKI, VIP, WanFang Data, CBM, Embase, PubMed and Cochrane Library clinical controlled trials database. After two researchers conducted screening and data extraction independently, the quality of the included literature research was evaluated according to the risk of bias tool described in the Cochrane Handbook version 5.1.0, and then RevMan 5.3 was used to undertake Meta analysis. Results A total of 21 articles about RCTs and semi-RCTs were obtained, including 2194 patients. Meta analysis indicated that GTT combined with antihistamine medicine treatment showed higher effective rates compared with the control group [RR=1.33, 95%CI (1.26, 1.40), P<0.000 01], with obviously lower recurrence rate [RR=0.45, 95%CI (0.33, 0.62), P<0.000 01]. There was no statistical significance in adverse reactions. Conclusion GTT combined with antihistamine medicine for CIU has definite efficacy, and is relatively safe. Whether apply GTT combined with antihistamine medicine for CIU should be verified through randomized controlled trial with large-scale samples, multiple centers and high quality.

Objective To retrospectively compare CT and MR features of hepatocellular adenoma with pathologic findings.Methods Twelve patients with histopathologically proved hepatocellular adenoma were classified on the basis of pathologic and genotype phenotype findings into four groups:steatotic type,cytological abnormality type,telangiectatic adenoma with inflammatory infiltrates type and atypical adenoma type.The CT and MR features of each type were reviewed retrospectively compared with the pathological results.Results In this retrospective study,12 patients were examined with CT (8 patients) and MR (8 patients).Among 12 patients,4 patients showed a steatotic type.One patient showed hypo-density on the non-enhanced CT and 3 patients demonstrated hypo-density on all phases of the post-contrast scans.Two lesions showed iso-intense signal on the in-phase T1 WI with signal dropout on the out-of-phase T1WI,and hypo-intense signal on the T2 WI with fat suppression sequences.One lesion demonstrated moderate hypointense signal on all phases of the post-contrast MRI scans.Two patients with the telangiectatic adenoma irflammatory infiltrates type were found.One patient showed hypo-density on the non-enhanced CT scans and hyper-density on all phases of the post-contrast CT scans.One patient demonstrated iso-intense signal and the other hypo-intense signal on the T1 WI,and both displayed moderate hyper-intense signal on the T2WI with fat suppression sequences and hyper-intense signal with gradual enhancement on all phases of post-contrast MR scans.There were 3 patients with a cytological abnormality type.One patient appeared hypodensity and 1 patient showed uniform iso-density on non-enhanced CT scans.All patients who had undergone contrast-enhanced CT scans were found to have hyper-density on the hepatic arterial-dominant phase and became slightly lower on the portal venous phase.On the delay phase the density reduced further.One mass showed iso-intense signal on the T1WI and hyper-intense signal on the T2WI with fat suppression sequences.There were 3 patients with an atypical adenoma type.One patient appeared uniform hypo-density on the nonenhanced CT and hyper-density on the hepatic arterial-dominant phase and became iso-dense on the portal venous phase.On the delay phase,it was slightly hyper-dense.Two out of the three lesions showed isointense and one hypo-intense signal on the in-phase T1 WI,and hypo-intense,hyper-intense,and iso-intense signal on the T2WI with fat suppression sequences,respectively.Two patients examined on all phases of post-contrast MRI scans.The result was similar to the CT findings.Conclusion The imaging features of hepatocellular adenoma are closely associated with pathological characteristics.
