Objective To explore the relationship between calcium-sensing receptor's expression and papillary thyroid carcinoma.Methods Seventy cases of postoperative papillary thyroid carcinoma were selected.Immunohistochemical technique was used to detect expression of calcium-sensing receptor in papillary thyroid carcinoma,thyroid benign lesions,and normal thyroid tissue,respectively.SPSS 17.0 statistical analysis was used with non parametric test,P＜0.05 indicated significant difference.Results The expression of calcium-sensing receptor in papillary thyroid carcinoma,benign thyroid,and normal thyroid were significantly different (90％,40％,0％,respectively; P ＜ 0.05).The expression of the calcium-sensing receptor in the group of papillary thyroid carcinoma with calcification was significantly higher than that in thyroid cancer without calcification (P ＜ 0.05).Conclusions This study suggests that the calcium-sensing receptor may be associated with papillary thyroid carcinoma and may play a key role in the calcification of the carcinoma.

Objective To explore the relationship between intestinal fatty acid binding protein(FABP2) gene G54A polymorphism and obesity,the effect of mutant 54A FABP2 gene on serum lipids metabolism.Methods The total of 84 subjects with obesity and 60 subjects with normal weight were involved in this study.The G54A FABP2 gene allele and genotype frequencies were detected by polymerase chain reaction (PCR)-restriction fragment length polymorphism(RFLP) technology.The automatic biochemical Analyzer was used to detect triglyceride(TG),high-density lipoprotein cholesterol(HDL-C) and low-density lipoprotein cholesterol(LDL-C) levels.Results The results of study on FABP2 gene polymorphism revealed as followed:in obese groups,the frequencies of GG,GA,A/A genotypes was 19.0%(16/84),73.8%(62/84) and 7.2%(6/84),respectively;in control group,the frequencies of G/G,G/A,A/A genotypes was 38.3%(23/60),58.3%(35/60),3.3%(2/60),respectively;the differences between two groups was statistically significant(χ2=6.97,P<0.05).In obesity group,the frequencies of alleles were 56.0%(94/168) for 54G and 44.0%(74/168) for 54A;in the control group,the frequencies of alleles were 67.5%(81/120) for 54G and 32.5%(39/120) for 54A;the differences between two groups was statistically significant(χ2=3.92,P<0.05).The plasma biochemical variables results showed as followed:in obesity group,the carriers of A/A homozygous genotypes and G/A heterozyous genotypes both had significantly higher plasma TG((2.36±0.82) mmol/L,(2.06±0.59) mmol/L,respectively)and LDL-C((3.94±0.96) mmol/L,(3.29±0.55) mmol/L,respectively)level than those with GG wild genotype(t=2.206,2.575,2.632,2.278;P<0.05).The level of HDL-C in the carriers of A/A homozygous genotypes((1.23±0.34) mmol/L)and in the carriers of G/A heterozyous genotypes((1.21±0.26) mmol/L) were not significantly different than those with GG wild genotype((1.29±0.31) mmol/L,P>0.05).The carriers of A/A homozygous genotypes had significantly higher plasma LDL-C((3.94±0.96) mmol/L)level than thosewith G/A wild genotype((3.94±0.96) mmol/L vs.(3.29±0.55) mmol/L,t=2.476,P<0.05),but the plasma TG((2.36±0.82) mmol/L vs.(2.06±0.59) mmol/L;P>0.05) and HDL-C((1.23±0.34) mmol/L vs.(1.21±0.26) mmol/L;P>0.05) level had not difference.Conclusion The FABP2 gene G54A polymorphism is related to obesity and lipid metabolism abnormality.The allele encoding in FABP2 gene may be a potential factor contributing to promoting lipid metabolism abnormality.

Objective To observe effect of aerobic exercise combined with inhalation of tiotropium on patients with stable chronic obstructive pulmonary disease (COPD) complicated with pulmonary hypertension.Methods A total of 98 patients with stable COPD and grade Ⅱ or Ⅲ pulmonary function complicated with pulmonary hypertension were recruited.They were divided into an observation group (n =31) and two control groups (n =30 and 37).Patients in control group 1 inhaled shahmette and fluticasone powder,and antibiotics as well as apophlegmatisant were also used in accordance with the demands of the patient's condition.Patients of in control group 2 inhaled tiotropium dry powder and accepted other therapeutic measures equivalent to those of control group1.The patients in the observation group were given aerobic exercise in addition to other therapeutic measures equivalent to those of control group 2.Six-minute walk test distances,pulmonary arterial systolic pressure and chronic obstructive pulmonary disease assessment test scores were compared after 6 months of treatment,among the groups and against the baseline values before treatment.Results After 6 months of treatment the average 6-minute walk distance,chronic obstructive pulmonary disease assessment score and pulmonary arterial systolic pressure of the observation group were all significantly better than for either of the control groups.Conclusions Inhaling tiotropium dry powder combined with aerobic exercise can reduce pulmonary artery systolic pressure and improve the symptoms as well as the quality of life for patients with stable COPD complicated by pulmonary hypertension.

Apoptosis of neutrophils controls the duration and the intensity of an inflammatory response and therefore the extent of neutrophil- mediated tissue damage, disturbance of neutrophil apoptosis has been associated with many diseases, underlying mechanism is not elucidated. C5a is a complement fragment that has multifunctional properties, which induces neutrophil chemoattraction, an oxidative burst, enhancement of phagocytosis, release of granule enzymes, and suppress neutrophil apoptosis. Several studies have reported calpain is involved in both neutrophil functions and apoptosis and it might play a more specific role in the regulation of neutrophil apoptosis. Diffenrent isoform of calpains is activted by diffenrent stimuli through different transduction pathway. It was reported previously that calpain is required for neutrophil migration and chemotaxis induced by C5a. In addition, autophagy is a ubiquitous physiological process that occurs in all eukaryotic cells and is considered to be a survival mechanism. Atg5 promotes autophagy and is indispensable to autophagosome formation. Upon calpain activation, Atg5 is cleaved and the resulting 24 ku Atg5 mediates apoptosis while losting the property of autophagy. Therefore, Atg5 represents a molecular switch between autophagy and apoptosis. The interaction among the C5a, calpain and Atg5 was introduced and new direction for further research was provided.
