Objective To investigate the clinical application value of serum gastric function detection in early gastric cancer screening.Methods Forty-two cases of gastric cancer,75 cases of benign gastric diseases and 44 individuals undergoing normal physical examination in our hospital from December 2015 to December 2015 were selected as the research subjects,performed the gastroscopic examiantion,simultaneously conducted the microscopic biopsy,and extracted blood for conducting the related indexes detection of gastric function,including pepsinogen Ⅰ (PG Ⅰ),pepsinogen Ⅱ (PG Ⅱ),PG Ⅰ/PG Ⅱ,gastrin 17 (G17) and helicobactor pylori(HP).Serum gastric function situation in the research subjects of 4 groups was studied.Results PG Ⅰ and PG Ⅰ/PG Ⅱ expressions from low to high were gastric cancer group,atrophic gastritis group,gastric ulcer group,superficial gastritis group and normal group respectively,the pairwise comparison had statistical difference (P<0.05);G17 in the normal group was lower that that in gastric ulcer group,atrophic gastritis group and gastric cancer group G17 in the gastric ulcer group was lower than that in the gastric cancer group,the differences were statistically significant (P<0.05).The HP positive rate in the normal group was lower than that in the superficial gastritis group,the superficial gastritis group was lower than the gastric ulcer group,the gastric ulcer group was lower than the atrophic gastritis group,and the atrophic gastritis group was lower the gastric cancer group,the differences had statistical significance (P<0.05).Conclusion Serum gastric function detection can better distinguish gastric benign lesions from malignant lesions,and can serve as an important indicator of early screening,which is easy to accept with low cost,for the patients with positive results,the gastroscopic examination should be conducted in order to improve the early diagnostic rate.

Objective Discuss the treatment mechanism of Xiaofeng Xuanqiao Decoction on guinea pig with al ergic rhinitis. [Methods]Sixty guinea pigs were randomized into 6 groups: normal control group, al ergic rhinitis(AR) group, high-dosage, equivalent-dosage, low-dosage Xiaofeng Xuanqiao decoction group, and loratadine group. AR guinea pig model was successful y established by ovalbumin(OVA) chal enge method. Xiaofeng Xuanqiao decoction and loratadine were applied to intervene AR guinea pig. The serum levels of IgE and IL-4, IFN-γ, histamine were determined by ELISA methods. [Results]The expression levels of IgE and IL-4, histamine significantly increased,meanwhile the level of IFN-γsignificantly lower compared with the normal group(P<0.01). Compared with that in AR model group, the serum level of IgE and IL-4, histamine in high-dosage Xiaofeng Xuanqiao decoction group significantly decreased,but the level of IFN-γ increased(P<0.01); the levels of IgE and IL-4, histamine decreased in other medication groups, meanwhile the level of IFN-γ increased compared with the model group(P<0.05).[Conclusion]Xiaofeng Xuanqiao can promote the produce of IFN-γ, inhibit the formation of IL-4, promote the secretion of Th1/Th2 cytokines to restore balance, to relieve eosinophil activation, reduce the synthet-ic of IgE, reduce the release of histamine, in many ways to prevent al ergic rhinitis inflammation, to achieve therapeutic effect.

Objective To investigate the association between preoperative serum TSH level and differentiated thyroid cancer (DTC).Methods The relationship between TSH concentration and differentiated thyroid cancer in 400 qualified patients with thyroid nodules was retrospectively analyzed from January 2009 to December2011 in our hospital.Based on the TSH values,the patients were divided into five groups.Results Preoperative serum TSH level in DTC group was higher than that in benign thyroid nodales group [(2.94 ± 1.74 vs1.92 ± 1.45) μ IU/ml,P＜0.01].The risk of DTC increased as serum level of TSH rose in the patients with thyroid nodule.The incidences of DTC were 27.8％,34.0％,40.0％,63.4％,and 70.2％ respectively in groups with TSH＜0.27,0.27-1.44,1.45-2.19,2.20-4.20,and ＞4.20 μIU/ml groups.TSH level in the group with cervical lymph node metastasis was higher than that without metastasis (P＜0.01).Conclusions The likelihood of thyroid cancer increases with increased serum TSH concentration.High TSH level seems to be associated with lymph node metastasis.Preoperative serum TSH level might be a risk predictor for DTC.

Objective To determine the relation between enlarged perihepatic lymph node (PLN) and viraemia,and to find out whether there is a difference in PLN size between the healthy individuals and patients with hepatitis C virus (HCV) infection. Methods Seventy-four patients with HCV infection and 283 healthy individuals were examined by two-dimensional ultrasound. The length and thickness of lymph node were measured. The lymph-node area index(LN area index) was calculated. The LN area index was evaluated by the ROC curve and compared with serum HCV core antigen (HCV-Ag) levels by correlation analysis. Results Detection rate, the length and thickness, LN area index of group with HCV infection were significantly different by compared with the normal control group ( P < 0. 001 ). The ROC curve showed that the LN area index as a diagnostic indicator had high sensitivity and specificity. The LN area index showed a significant correlation with HCV-Ag level (r = 0.436, P <0.05), but no significant differences were found between LN area index and HCV-Ag grade. Conclusions Perihepatic lymphadenopathy indicates viraemia,and LN area index of 100 mm2 is a reference index in estimating whether patients have HCV infection.

The effect of iodinated contrast on thyroid function and auto-antibodies after a single percutaneous coronary intervention (PCI) was explored.In 96 patients with randomly selected PCI,serum TSH,T3,T4,thyroid peroxidase antibody (TPOAb),thyroglobulin antibody (TgAb) were determined preoperatively as well as by 3-6 months postoperatively.After PCI,the level of TSH,T3,T4,showed no significant changes; TgAb,TPOAb which were positive preoperatively,after 3-6 months were statistically increased(P＜0.05).Iodinated contrast in PCI has no significant influence on thyroid function and auto-antibodies after 3-6 months.
