Objective To investigate the expression of NEK2(NIMA-related kinase 2)in prostate cancer as well as benign prostatic hyperplasia,and the involvement of NEK2 in the prognosis of prostate caner(PCa). Methods The different expression of NEK2 in the tissue of prostate cancer and the adjacent benign tissues of prostate were measured by real-time quantitative reverse transcriptase-polymerase chain reaction (QRT-PCR) analysis and immunohositochemistry analysis,and then bioinformatically analyzed using the Taylor dataset. Results QRT-PCR showed that NEK2 was highly expressed in PCa than in the adjacent benign tissues (6.93±0.15 vs 5.38±0.4,t=6.25,P=0.003). Immunohositochemistry analysis showed the expression of NEK2 was higher in PCa than in the adjacent benign tissues(5.84±0.56 vs 4.27±0.49,t=5.38, P<0.001). Furthermore, the biochemical recurrence-free time of PCa patients in high NEK2 expression groups significantly reduced( χ²=4.33,P=0.037). The overall survival time of PCa patients was not correlated to NEK2 expression levels( χ²=0.27,P=0.605). Conclusion The above findings suggest that NEK2 is associated with production and development of PCa, and also critically connected with the process of PCa,which indicate that we can predict the probability of the biochemical recurrence-free time by detecting the expression of NEK2 in PCa patients,and NEK2 can also become a potential biomarker for PCa prognosis.

Objective To explore the diagnosis and treatment of primary carnitine deficiency. To identify potential mutation of SLC22A5 gene in two children affected with primary carnitine deficiency and provide genetic counseling. Methods We measured the free camitine(Co)and acylcamitine levels in a suspected clinical inherited metabolic diseases by tandem mass spectrometry. The SLC22A5 gene mutations were tested to the children with low Co level and the diagnosis was made. Then, We measured the free camitine(Co)and acylcamitine levels and SLC22A5 gene mutations in her sister. The children with PCD were treated with carnitine and followed up for 11 months. The SLC22A5 gene was detected in their family. Results In two children affected with PCD, 1 case was clinical children, another case of their sister was no obvious clinical manifestations. Mutations were found in all of them.The average C0 level in patients was lower than the reference value,along with decreased level of different acylcamitines. Two cases were treated with earnitine. Their clinical symptoms reduced 2 months later. Another case had not been sick. The CO level and different acylcamitines level in the blood rose to normal. A homozygous mutation C. 760C>T (P. Arg254X)of the SLC22A5 gene was detected in the two cases.Heterozygous mutation C. 760C>T (P.Arg254X) was also found in other family members. Conclusion Two patients were diagnosed with PCD by the test levels of free carnitine and acylcarnitines in blood with tandem mass spectrometry,and gene mutation test. L-carnitine supplement had a good effect in treatment of the PCD patients.C.760C> T (P.Arg254X) mutations of the SLC22A5 gene is the deleterious mutations for PCD families, The analysis method of the wrong mutagenesis and shear changes which is used to directly sequence the exons codes of the SLC22A5 gene can provide genetic counseling for PCD families.

目的 观察芳香烃受体(AhR)及Th17相关细胞因子在类风湿关节炎中的表达水平及其对疾病的预测价值。方法 选择2014年1月—2015年12月于我院就诊的RA患者60例作为观察组,选取同期于我院进行健康体检的正常人60例作为对照组,采用酶联免疫吸附法检测血清中 IL-17、IL-23及AhR的表达水平,并分析其与疾病活动度的关系。结果 RA患者血清IL-17、IL-23及AhR水平高于对照组(P＜0.05)。而根据病情严重程度,RA 非早期组IL-17、IL-23及AhR水平较早期组增高(P＜0.05)。血清 IL-17 水平与除CRP以外的病情活动度指标均呈正相关关系(P＜0.05)。IL-23 水平与SJC、TJC、HAQ 、DAS28 评分呈正相关关系(P＜0.05),但其他指标无明显相关性(P>0.05)。RA患者PBMC中AhR的表达水平与各项临床指标无相关性(P>0.05)。IL-17和IL-23水平与Sharp评分呈正相关关系(r=0.895,P＜0.01;r=0.708,P＜0.01)。AhR的表达与血清IL-17和IL-23水平呈正相关(r=0.415,P＜0.01)。经荧光定量PCR检测结果显示,RA患者AhR及其下游因子CYP1A1、IL-17、FOXP3 mRNA的表达水平高于对照组(P＜0.05)。且RA 非早期组AhR及其下游因子CYP1A1、IL-17、FOXP3 mRNA的表达水平较早期组增高(P＜0.05)。经相关关系检测,RA患者AhR及其下游因子CYP1A1、IL-17、FOXP3 mRNA的表达水平与Sharp评分呈正相关关系(r=0.715,P＜0.01;r=0.734,P＜0.01;r=0.812,P＜0.01;r=0.755,P＜0.01)。结论 Th17相关细胞因子IL-17和IL-23在RA病理生理过程中发挥重要作用,其表达增高,提示关节炎症处于活跃状态,骨质破坏较重,可作为评估RA病情的重要指标。RA患者体内AhR蛋白及其相关下游信号通路均呈高表达状态,AhR通路在RA患者的发病过程中可能发挥关键作用。

Objective To observe the expression level of aroma receptor (AhR) and Th17 related cytokines in rheumatoid arthritis and its predictive value to disease. Methods Sixty patients with RA who were treated in our hospital from January 2014 to December 2015 were selected as the observation group. Sixty healthy subjects were randomly selected as the control group. IL-17, IL-23 and AhR levels in serum were detected by enzyme-linked immunosorbent and the relationship between IL-17, IL-23 and disease activity were analyzed. Results IL-17, IL-23 and AhR levels in serum of RA patients were significantly higher than those in controls (P<0.05). However, the levels of IL-17, IL-23 and AhR levels were significantly higher in the non- early RA group than in the early group (P<0.05), depending on the severity of the disease. There was a positive correlation between serum IL-17 level and disease activity index except CRP (P<0.05). IL-23 level was positively correlated with SJC, TJC, HAQ and DAS28 scores (P<0.05), but no significant correlation was found between other indexes (P>0.05). The expression level of AhR in PBMC of RA patients was not correlated with clinical indexes (P>0.05). IL-17 and IL-23 levels were positively correlated with Sharp score (r=0.895, P<0.01; r=0.708, P<0.01). The expression of AhR was positively correlated with serum IL-17 and IL-23 levels (r=0.415, P<0.01). The expression of AhR and its downstream factors CYP1A1, IL-17 and FOXP3 mRNA in RA patients were significantly higher than those in the control group (P<0.05) by fluorescence quantitative PCR. The expression of AhR and its downstream factors CYP1A1, IL-17 and FOXP3 mRNA in RA group were significantly higher than those in early group (P<0.05). The expression level of AhR and its downstream factors CYP1A1, IL-17 and FOXP3 mRNA in RA patients were positively correlated with Sharp scores (r=0.715, P<0.01; r=0.734, P<0.01; r=0.812, P<0.01; r=0.755, P<0.01). Conclusion The Th17-related cytokines IL-17 and IL-23 play an important role in the pathophysiology of RA, and the expression of Th17-associated cytokines is increased, suggesting that arthritis is active and bone destruction is serious. The AhR protein and its associated downstream signaling pathways are highly expressed in RA patients, and the AhR pathway may play a key role in the pathogenesis of RA patients.

Objective To investigate the therapeutic effects and mechanisms of tetramethylpyrazine (TMP) on streptozocin(STZ)-induced-nephropathy in type 2 diabetic rats. Methods 50 SD rats were randomly divided into normal group(n=10) and model group(n=40). The model rats were fed on high fat and sugar diets for 4 weeks, then given STZ(40 mg/kg,ip). After 72 hours, the fasting blood glucose (FBG) was measured. Rats with high FBG above 16.67mmol/L were randomly divided into four groups: model, metformin(Met, 250 mg/kg)and TMP (80 mg/kg, 160 mg/kg) groups for treating 8 weeks, and both the control and model groups were given equals distilled water by intragastric administration. At the end of the experiment, blood glucose, urine protein, blood urea nitrogen and creatinine were measured. The expression of TLR4 and caspase3 protein in kidney tissue of rats was determined by immunohistochemistry. Pathological changes of kidney were observed under light microscope. Results Compared with the model group, metformin and high dose of TMP administered after 8 weeks, rats can significantly reduce the dynamic fasting blood glucose(P<0.05). Urinary protein excretion of total dynamic decreased significantly (P<0.01, P<0.05); the protein expression of TLR4 and caspase3 in the metformin group and high dose group was significantly lower than that in the model group (P<0.05); kidney tissue pathological damage was significantly reduced. Conclusion TMP has a protective effect on STZ induced nephropathy in type 2 diabetic rats, and its mechanism may be related to the down-regulation of TLR4 expression.
