Objective To investigated the association between bone morphogenetic proteins-2 (BMP-2)gene mutation and coal-burning skeletal fluorosis of children in Zhijin Guizhou.Methods In 2010,121 cases of children with skeletal fluorosis were diagnosed based on the standard X-ray Diagnosis of Skeletal Fluorosis (WS192-1999) in coal-burning skeletal fluorosis areas in Zhijin Guizhou,and 50 cases of them were selected as skeletal fluorosis group.Thirty healthy children free of skeletal fluorosis,rickets and other bone related diseases excluded by X-ray were selected as a control group in the same area.Using polymcrase chain reaction combined with DNA sequencing technology,all three exons of BMP-2 gene were conducted sequence screening in skeletal fluorosis and the control groups to detect gene mutations.Results ①The T insertion mutation on exon 1 between 401-402 bp:the T insertion mutantion genotype frequencies of skeletal fluorosis group and the control group were 27.7％ (13/47)and 7.1％ (2/28),and the difference was statistically significant (x2 =4.600,P ＜ 0.05),adjusted OR value of 4.62(1.94-10.90).②)The 894 bp T→G mutation on exon 2:the TG genotype frequencies of skeletal fluorosis group and the control group were 14.0％ (7/50) and 16.7％(5/30),and the difference were not statistically significant (x2=0.103,P＞ 0.05).③The 1 046 bp A→G mutation on exon 2:the AA,AG,GG genotype frequencies of skeletal fluorosis group and the control group was 30.0％ (15/50),24.0％ (12/50),46.0％ (23/50) and 50.0％ (15/30),20.0％(6/30),30.0％ (9/30),and the differences were not statistically significant (x2 =3.099,P ＞ 0.05).Conclusion Exon 1at 401-402 bp,T insertion mutation and skeletal fluorosis are closely related.The relationship between A→Gmutation in exon 2 at 1 046 bp and skeletal fluorosis is not significant.

Objective To detect the expressions of chemokine CXCL5 and its receptor CXCR2 in hepatocellular carcinoma (HCC), investigate their relationships between CXCL5, CXCR2 and clinicopathologic features and probe into the significance in the evaluation of prognosis. Methods Immunohistochemical Envision method was utilized to detect the expressions of CXCL5 and CXCR2 in HCC , to explore their relationship between CXCL5, CXCR2 and clinicopathologic features and MVD in HCC. Results (1) The high expression rates of CXCL5 and CXCR2 protein was 64.7% and 68.6%, respectively, significantly higher than those in adjacent tissues of HCC(17.6%, 15.7%, P < 0.05). The overexpression of CXCL5 protein had correlation with tumor size, differentiation, TNM stage and vascular invasion (P < 0.05) and the overexpression of CXCR2 protein did with tumor grade and vascular invasion (P < 0.05). (2) The value of MVD was higher in HCC than that in the adjacent tissues of HCC (P < 0.05), and had positive correlation with the expressions of CXCL5, and CXCR2 proteins. (3) The higher rates of recurrence and metastasis were in the groups of higher expression of CXCL5 and CXCR2 proteins (P < 0.05). Conclusions The overexpressions of CXCL5 and CXCR2 may promote the occurrence and development of HCC as well as the neovasculation in HCC. Therefore, they can be used as markers to evaluate the prognosis of HCC.

As an important branch of systematic biology, metabonomics is an emerging discipline following genomics, proteomics and transcriptomics. It focuses on the quality and quantity changes of the small molecular metabolites in appointed physiological or pathological state, and provides important informa?tion for studies of diseases mechanism, clinical early diagnosis and prognosis prediction. Compared with tra?ditional clinical diagnostic method ( single index) , metabonomics method can more comprehensively analyze metabolites changes in the body. This review introduces the metabonomics and summarizes its application in thyroid diseases.

The DNA fragment RM07 was isolated from halophilic archaea Halobacterium halobium, which can function as promoter not only in halophilic archaea, but also in Escherichia coli as eubacterial promoter. Sequencing analysis indicated that it possessed the typical consensus sequences (-35 and -10) of bacterial gene promoter, which was confirmed by further deletion analysis: With its -35 sequence deleted and -10 sequence left,DNA fragment RM07a nearly cannot initiate transcription;With its both -35 and -10 sequences,RM07b DNA fragment could be active as promoter at a level even higher than RM07. Our research also showed that the promoter function of RM07 fragment in Escherichia coli was under the control of environmental factors,especially its positive correlation with the increasing concentration of sodium chloride. Therefore, RM07 DNA fragment may be potential1 novel promoter source for constructing double-function vectors. It also has special significance in elucidating the issues of the fusing characteristics of archaea and lateral gene transfer between archaea and bacteria.

Characteristics and measurement principles of reference methods in clinical biochemistry were described.Implementation of reference systems is one of the most effective approaches to improve the accuracy and comparability of clinical laboratory test results.Reference methods are the key components of reference systems.Reference methods should have measurement uncertainties that meet the requirements of the intended use,and thus should be based on reliable measurement principles.For the well-defined biochemistry analytes,reference methods have been almost all based on instrumental analysis.Isotope dilution mass spectrometry (ID/MS) is considered most reliable and has been the major analytical principle of the reference methods.ID/MS analysis is accurate but expensive.Use of other validated instrumental analyses as reference measurement principles would be justified.

The ideal treatment and recovery of osteoarticular injury remain to be resolved. Small intestinal submucosa (SIS), a naturally-occurring decellularized extracellular matrix, has been recognized as an ideal scaffold for tissue engineering and widely used in repairing various tissues and organs. Nowadays its application has also been gradually increased in the field of orthopedics. We reviewed laboratorial studies and clinical trails about the application of SIS in bone and joint repair, aiming to evaluate its effects on the repair of bone, cartilage, meniscus, ligament and tendon. SIS has showed promising results in repairing bone, meniscus, ligament or tendon. However, additional studies will be required to further evaluate its effects on articular cartilage and tendon-bone healing. How to optimize SIS material,is also a focused problem concerned with making SIS a potential therapeutic option with high value for orthopedic tissue repair.

Objective To observe the apoptosis of human large cell lung cancer NCI-H661 cells induced by crotoxin,and to explore its mechanism. Methods The growth suppression of crotoxin on the NCI-H661 cells was detected by CCK-8 colorimetry,and the formation of NCI-H661 cells was observed by the plat colony experiment. This experiment included 4 groups:negative control group,crotoxin group(60 μg/ ml cro-toxin acted for 24 h),crotoxin + SB203580 group(pretreated cells using 5 μmol/ L SB203580 for 1 h,then 60 μg/ ml crotoxin acted for 24 h),SB203580 group(pretreated cells using 5 μmol/ L SB203580 for 1 h,then cultivated cells using complete culture solution). They were detected that the cell cycle and apoptosis rate of NCI-H661 cells treated with crotoxin by the flow cytometry. Additionally,they were tested that the change of the cell cycle and apoptosis rate after the NCI-H661 cells were treated with crotoxin and the activity of p38MAPK was inhibited by SB203580. Results When the concentration of crotoxin was greater than or equal to 30 μg/ ml,the inhibitory effect of crotoxin on the activity of NCI-H661 cells and colony formation,and inhibi-tion rate rose with increasing function of time and drug concentration. Flow cytometry showed that the apoptosis rate of crotoxin group and crotoxin + SB203580 group were(16. 70 ± 1. 38)% and(2. 15 ± 0. 54)% ,com-pared to the control group(1. 47 ± 0. 29)% ,and the former difference was statistically significant and the latter was not statistically significant(t = - 18. 763,P = 0. 000;t = - 1. 935,P = 0. 125). The G1 period cells of crotoxin group and crotoxin + SB203580 group were(57. 25 ± 1. 09)% and(48. 04 ± 1. 03)% ,compared to the control group(47. 46 ± 0. 69)% ,and the former difference was statistically significant and the latter was not statistically significant(t = - 13. 124,P = 0. 000;t = - 0. 809,P = 0. 464). Conclusion Crotoxin can promote the apoptosis of human large cell lung cancer NCI-H661 cells,and this effect may be related to the excitation of p38MAPK signal pathway.
