Objective To observe the changes in the pathological diagnosis rate of Graves'disease(GD) and Hashimoto's thyroiditis(HT)in the past 28 years and to probe its relationship to the environmental factors. Methods Statistic analysis was performed on data of thyroid disease,GD,HT and the complications of HT in Department of Pathology(1978-2005)in General Hospital of Tianjin Medical University with Run test,Cox-stuart test,ANOVA,t or t'test and Chi-square test.Results In 28 years there were 243 403 biopsies(average 8 693/ year)including 6 771 cases of thyroid disease(27.8‰),216 cases of GD(0.89‰),352 cases of HT (1.45‰).The biopsy rate of thyroid disease and GD showed a descending tendency since 1982 but an ascending tendency from 1995,furthermore,with GD it showed a descending tendency from 2001 to 2005 once more.While the biopsy rate of HT and GD+HT showed a descending tendency from 1986 and an ascending tendency after 1996,being 1-4 years later than thyroid disease and GD.The biopsy rate of GD+HT and the proportion of HT showed a descending tendency in 2002-2005 and 2003-2005 respecitvely.The average age of total and female patients with GD showed a descending tendency from 1997.The average age of GD was 13.7 years younger than HT,the patients of GDⅠ-type andⅡ-type being younger thanⅢ-type.The average age of lymphoid type(L), oxyphilie epithelium type(O),pronounced epithelium destruction type(P)in HT increased sequentially.In 28 years,there were more female patients with GD and HT,especially with HT.There existed 7.95% hyperthyroidism,6.25% nodular goiter,2.27% carcinoma in HT(more in L-type)and 2.56% hypothyroidism in HT(more in P-type).Conclusion Within 28 years,according to the pathological diagnosis rate,GD,HT,and GD+HT showed phasic tendencies related to drinking low iodine water and the implement of universal salt iodization policies in 1994 and 2000.Therefore,on the levels of genetics and environment,the factors that influence autoimmunity of thyroid gland could not exclude the variations of iodine intake,infection,affection or emotional stress.The mechanism of the changes in the pathological diagnosis rate needs further study.

Objective To investigate the effects of Panax notoginseng saponins(PNS,三七总皂苷) on extra-vascular lung water(EVLW) and respiratory dynamics in dog with oleic acid induced acute lung injury(ALI).Methods Eighteen Beagle dogs,intubated and mechanically ventilated with intermittent positive pressure ventilation(IPPV) mode(tidal volume(VT) 10 ml/kg, positive end-expiratory pressure(PEEP) 0,inspiratory oxygen concentration(FiO2) 1.00),were randomly assigned into three groups(each n=6): normal control group,ALI model group(induced by intravenous injection of oleic acid) and PNS group(received PNS after the ALI model was constructed).PNS 10 mg/kg being dissolved in 100 ml 5% glucose solution(GS) was pumped into central vein (2.5 ml/min) after ALI model was formed in the PNS group.Similar amount of glucose solution was given to the normal control and model groups.Respiratory dynamics and arterial blood gas(ABG) were monitored every hour.Four hours after the establishment of ALI,the dogs were sacrificed and extra-vascular lung water index(EVLWI) was quantified by a gravimetric measurement.Results In ALI dogs,PNS significantly decreased the index of EVLWI((14.10?1.45) ml/kg vs.(17.97?0.85) ml/kg,P0.05).Conclusion PNS has certain protective effect on dog with oleic acid induced ALI,it may lower EVLW and elevate the Cst total,that is beneficial to the improvement of hypoxemia.

Objective To analyze the curative effect of oxaliplatin combined with S-1 in the treatment of advanced colorectal cancer.Methods Totally 90 cases of patients with advanced colorectal cancer in Shangluo No.2 Provincial People's Hospital from January 2013 to August 2015 were divided into observation group and control group,45 cases in each group.Patients in control group were treated with oxaliplatin combined with fluorouracil,4 weeks for one cycle of treatment,and patients in observation group were treated with oxaliplatin combined with S-l,21 d for one cycle.The curative effects,adverse reactions,life quality,and one year survival rate were compared between two groups.Results After treatment,the total remission rate of observation group was higher than that of control group,and the disease control rate was lower than that of the control group,but there was no significant difference between the two groups.During the treatment,there were no significant differences in Ⅰ degree and Ⅱ degree adverse reactions between two groups;But the adverse reactions of level Ⅲ and level Ⅳ of gastrointestinal reaction,liver function damage,reduce the incidence of white blood cells in observation group were significantly lower than that of control group (P ＜ 0.05).There was no significant difference between the two groups in the SF-36 scale scores.The one year survival rate of observation group was (21/45),and the survival rate of the control group after treatment was 42.22％ (19/45) in the control group,and there was no significant difference between the two groups in the one year survival rate.Conclusion Compared with oxaliplatin combined with fluorouracil,oxaliplatin combined with S-1 has equivalent efficacy and life quality,but the adverse reactions in gastrointestinal tract,liver,and marrow were better.
