BACKGROUND:The molecular mechanism of traumatic deep vein thrombosis is complex.Numerous studies focus on clinical observation and epidemiology,but its molecular mechanism has not been a new breakthrough.OBJECTIVE:By use of gene array technology,this study was aimed to study the expression changes of matrix metalloproteinases in rat models of traumatic deep vein thrombosis,and to explore the roles of matrix metalloproteinases in traumatic deep venous thrombosis.METHODS:A total of 150 SD rats,SPF grade,of 8-12 weeks old,body weight of 250-300 g,were divided at random into normal control group (n=10) and model group (n=140).Rat traumatic deep venous thrombosis models were set up by clamping the femoral vein and fixing the bilateral hind limbs,and the fixation of hip spica with plaster bandage was conducted in each group.Then rats were divided into 7 subgroups:post-traumatic 0.5 hours,post-traumatic 2.5 hours (initial period of thrombosis),post-traumatic 25 hours (thrombogenesis at thrombotic crest-time),post-traumatic 25 hours non-thrombogenesis at the thrombotic crest-time),post-traumatic 72 hours (thrombus resolution),post-traumatic 72 hours thrombus insolution) and post-traumatic 168 hours (nonthrombosis).At the corresponding phasess,the femoral vein tissues were incised,and total RNA of femoral vein was extracted using Trizol one-step method.Applying Genechip Rat Genome 430 2.0 genechips,the gene expressions in femoral vein were detected in different groups.The rate of traumatic deep venous thrombogenesis and non-thrombogenesis,the rate of thrombi solution and insolution were observed;the expressions of matrix metalloproteinases and tissue inhibitor of metalloproteinases at different time phases was detected by gene array data analysis.RESULTS AND CONCLUSION:Three model rats died and the remaining 147 rats were involved in the final analysis.At the post-traumatic 25 hours,the rate of thrombogenesis was 50.5% and nonthrombogenesis was 49.5%.To the post-traumatic 168 hours,the rate of thrombus solution was 56.7% and thrombus insolution was 43.3%.Both matrix metalloproteinases and tissue inhibitor of metalloproteinases exhibited differential expressions in the course of traumatic deep venous thrombosis.Under the thrombus insolution state,matrix metalloproteinases continued to show a high expression,tissue inhibitor of metalloproteinase expression was down-regulated in the thrombus formation,was significantly inhibited in the thrombus insoluUon process.In the process of traumatic deep vein thrombosis and insolution,matrix metalloproteinase was closely related to traumatic deep vein thrombosis,the matrix metalloproteinase/tissue inhibitor of metalloproteinases are likely to affect the biological state of thrombosis.

BACKGROUND:There is lack of an effective measuring means to diagnose deep venous thrombosis (DVT) in clinic.KLF2 and KLF4 are down-expressed at prethrombotic state,which may be served as predictive molecular markers to diagnose DVT.OBJECTIVE:To explore the feasibility of KLF2 and KLF4 as molecular markers to prediagnose DVT in rats.METHODS:Totally 90 rats were obtained from 100 rats to establish traumatic DVT models and divided into the prethrombotic,thrombosis crest-time and non-thrombosis groups.The remained 10 rats served as control group.Rat blood was collected at each time point,and the expressions of KLF2 and KLF4 were detected by real-time PCR.RESULTS AND CONCLUSION:The KLF2 and KLF4 mRNA expressions in the prethrombotic group and thrombosis crest-time group were lower than that of the control group.However,the KLF2 and KLF4 mRNA expressions in the non-thrombosis group was higher than that of the control group.Therefore,KLF2 and KLF4 may be candidate molecular markers for prediagnosis of DVT in rats.

BACKGROUND: Deep venous thrombosis (DVT) always occurs after orthopedic surgery. At present, clinical diagnosis of DVT has been lack of an effective measuring means for a long time. Cathepsin may be an effective biological marker of DVT. OBJECTIVE: To study the expression change of cathepsin B and cathepsin C in the rat blood cells before and after DVT and to investigate the feasibility of cathepsin B and cathepsin C as candidate molecular markers for early diagnosis of DVT. METHODS: Totally 100 Sprague Dawley rats were randomly divided into normal control group (n=10) and model group (n=90). Rat traumatic deep vein thrombosis models were established by clamping the femoral vein and fixing the bilateral hind limbs. According to observation time points and the different situations of thrombosis, rat models were assigned to three subgroups: pre-thrombosis, intra-thrombosis, and non-thrombosis. Blood RNA of each group was extracted and reverse transcribed into cDNA. The expression of cathepsin B and cathepsin C in blood cells was detected using real-time fluorescence quantitative PCR. RESULTS AND CONCLUSUON: Expression of cathepsin B and cathepsin C in the blood cells was obviously expressed in the intra-thrombosis subgroup. There was no significant difference in cathepsin B and cathepsin C expression between pre-thrombosis, non-thrombosis groups and normal control group. These findings suggest that cathepsin B and cathepsin C are closely related to DVP and they can be used as the candidate molecular markers for early diagnosis of DVT.

Objective To establish reference interval of thyroid hormones in pregnant women in Urumqi,standardize the diagnostic criteria of thyroid diseases in pregnancy,assess the iodine nutrition and thyroid function at different stages of pregnancy,and provide evidence to guide iodine supplementation.Methods A cross-sectional survey was performed in 3 731 pregnant women in Urumqi from May 2015 to June 2016.1 206 of them were in the first trimester,1 125 in the second and 1 400 in the third.500 non-pregnant women were recruited as controls.Levels of serum thyrotrophin (TSH),free triiodothyrunine (FT3),free thyroxine (FT4),anti-thyroid peroxidase (anti-TPO) and antithyroglobulin (anti-TG) were measured,and urinary iodine levels were detected by arsenic-cerium catalytic spectrophotometry.Results There were statistically significant differences between the pregnant groups and the control group in FT3,FT4,and TSH levels (P＜0.05).The serum thyroid concentrations in each group were FT3 values:(4.64±1.15),(4.36±0.89),(3.89±0.92),(5.24±0.65) pmol/L;FT4:(16.49±2.78),(15.06±3.76),(12.38± 1.65),(17.56± 1.12) pmol/L;TSH:(1.98±0.65),(2.43 ±0.83),(3.15± 1.25),(2.13 ± 0.75) mU/L.The reference intervals of thyroid hormones in early,middle and late pregnancy (P2.5 to P97.5) were:FT3:3.24-7.58,3.16-5.47,3.05-4.28 pmol/L;FT4:13.36-22.58,12.04-19.77,12.78-20.03 pmoL/L;TSH:0.24-3.78,0.51-3.91,0.55-4.55 mU/L.The medians of anti-TG and anti-TPO at different stages of pregnancy were significantly different,with the first trimester being the lowest and the third trimester being the highest (P=0.07,0.04).The medians of urinary iodine in all four groups were 235.78 μg/L (controls),198.25 μg/L (first trimester),175.36 pg,/L (second trimester) and 141.24 μg/L (third trimester),showing a significant gestational age-dependent decrease (P =0.036).Changes in serum levels of TSH,FT3,FT4,anti-TG and anti-TPO seemed to be in accordance with changes of urinary iodine levels;yet the correlations were not statistically significant (P＞0.05).Conclusions Iodine nutritional status was closely related to gestational age.Abnormal TSH levels were mainly observed in the second and third trimesters,abnormal serum levels of FT3,FT4,anti-TG and anti-TPO in the first trimester,and iodine deficiency in the third trimester.Thyroid function and urinary iodine should be monitored at each trimester during pregnancy.

Objective: To investigate the role of microRNA-96-5p in the proliferation and invasion of gastric cancer cells and its molecular mechanism. Methods: From June 2015 to January 2017, 53 resected specimens were collected. The transcriptional levels of microRNA-96-5p and forkhead box Q1 (FoxQ1) in gastric cancer tissues and the matched para-cancerous tissues were quantified by quantitative real-time PCR (qRT-PCR). The expression of FoxQ1 protein was also detected by immunohistochemistry (IHC). The relationship between microRNA-96-5p expression and the clinicopathological features of gastric cancer and its correlation with FoxQ1 expression were analyzed. The expressions of miRNA-96-5p in gastric cancer tissue and adjacent normal tissue were detected by qRT-PCR. miRNA-96-5p mimics was transfected to BGC-823 gastric cancer cells. The effects of miRNA-96-5p on cell proliferation and invasion were detected by cell counting kit-8 (CCK-8) assay and Transwell assay, respectively. The protein expressions of FoxQ1, E-cadherin and vimentin were determined by western blot. The relationship between FoxQ1 and miRNA-96-5p expressed in BGC-823 cells was detected by dual-luciferase reporter assay. Results: The median expression of miRNA-96-5p in gastric cancer tissue was 1.05, significantly lower than 3.23 of para-cancerous tissues (P<0.05). The positive rate of FoxQ1 expression in gastric cancer tissue was 71.7%, significantly higher than 28.3% of para-cancerous tissues (P<0.05). The expression of FoxQ1 was negatively corelated with the level of miRNA-96-5p (r=-0.613, P=0.006). The expression of miRNA-96-5p in gastric cancer cell BGC-823 was significantly decreased compared with normal gastric epithelial cell (0.96±0.08 vs 2.84±0.15, P<0.05). The results of CCK-8 assay and Transwell assay showed that overexpression of miRNA-96-5p significantly reduced the proliferation and invasion abilities of gastric cancer cells (P<0.05). Overexpression of miRNA-96-5p decreased the protein level of FoxQ1. Moreover, it upregulated the expression of E-cadherin and downregulated the expression of vimentin. The result of dual-luciferase-3′-UTR reporter assay confirmed that miRNA-96-5p binds to the 3′UTR of FoxQ1. Conclusion miRNA-96-5p may suppress the proliferation, migration and epithelial-mesenchymal transition (EMT) of gastric cancer cell by down-regulation of FoxQ1.
