Objective: Invasion and metastasis are the main causes of carcinoma mortality; hence, the timely blocking of the invasion and metastasis of carcinoma has become a research hotspot. The present study aims to investigate the expression levels of Tiam-1 mRNA and HPA-1 mRNA and their correlation with the invasion and metastasis of hepatocellular carcinoma. Methods: From May 2009 to Jan 2012, 65 hepatocellular carcinoma patients admitted consecutively in our hospital for surgical treatment were included in this study. Real-time fluorescent quantitative reverse transcriptase polymerase chain reaction (RT-PCR) was used to investigate the expression levels of Tiam-1 mRNA and HPA-1 mRNA in hepatocellular carcinoma, paired adjacent hepatocellular carcinoma (2 cm from the carcinoma), and surgical marginal normal hepato mucosa tissues (5 cm from the carcinoma). RT-PCR was also used to analyze their correlation with the clinicopathological characteristics of hepatocellular carcinoma. Results: The expression level of HPA-1 mRNA was significantly higher in hepatocellular carcinoma (43.83±11.62) than in paired adjacent hepatocellular carcinoma (14.82±8.16) and normal hepato mucosa tissues (6.02±5.36) (P<0.001). The expression level of HPA-1 mRNA was higher in paired adjacent hepatocellular carcinoma than in normal hepato mucosa tissues (P<0.05). The expression of Tiam-1 mRNA was higher in hepatocellular carcinoma (35.28±11.81) than in paired adjacent hepatocellular carcinoma (12.94±6.25) and normal hepato mucosa tissues (4.17±3.49) (P<0.05). The expression level of Tiam-1 mRNA was higher in paired adjacent hepatocellular carcinoma than in normal hepato mucosa tissues (P<0.05). The expression levels of Tiam-1 mRNA and HPA-1 mRNA were closely associated with the degree of differentiation, depth of infiltration, lymph node metastasis, vessel metastasis, and TNM (Tumor, Node, Metastasis)staging of gastric carcinoma (P<0.05). Spearman rank correlation analysis demonstrated a significant correlation between Tiam-1 and HPA-1 (OR=0.523, P<0.05). Conclusion: The expression levels of Tiam-1 mRNA and HPA-1 mRNA were high in hepatocellular carcinoma. Meanwhile, the increased ex-pression levels of Tiam-1 and HPA-1 can promote the invasion and metastasis of hepatocellular carcinoma. Moreover, the determination of Tiam-1 and HPA-1 may be valuable for the treatment and prognosis of hepatocellular carcinoma.

Objective:
To examine the retention rate and caries prevention effect of fit-and-fissure sealants after 3 years of children oral disease comprehensive intervention program in Henan province.
Methods:
For each of the five provincial regions attending the program in 2015, two classes from grade 2 in four primary schools were selected. Children in two schools were assigned into intervention group and the first permanent molars which were appriopriate for sealing were sealed with pit-and-fissure sealants. Children in other two schools were included in the control group and the first permanent molars were only examined for caries conditions. Three years later, retention rate of pit-and-fissure sealants and the dental caries prevalence was compared.
Results:
Complete retention rate of sealants in the first permanent molars was 65.55% and the whole retention rate was 94.78%. The caries incidence and mean value of the first permanent molars in the intervention group children was 9.71%, (0.12±0.40) respectively whereas those in control group was 21.90%, (0.39±0.78) respectively. The differences between two groups were statistically significant(χ2/t=27.76, 6.91, P<0.01). The relatively effective rate of sealing for caries reduction was 63.43% and the actural effective rate was 6.51% and the pure yield rate of sealing was 12.19%. Higher sealant retention rate was associated caries prevalence(χ2=153.28, P<0.01).
Conclusion
Childhood oral disease intervention project in Henan Province shows positive effects. Sealing of the first permanent molars effectively prevent dental pit and fissure caries.

OBJECTIVE:
To explore the genetic etiology for a Chinese pedigree affected with Alazami syndrome.
METHODS:
Genomic DNA was extracted for 2 patients and 2 unaffected members from the pedigree. Whole exome sequencing was carried out to detect potential variant in the proband, and the result was verified by Sanger sequencing.
RESULTS:
The proband and her sister were both found to harbor compound heterozygous variants of LARP7 gene, namely c.94A>T (p.Lys32*) and c.1141A>G (p.Lys381Glu), which were inherited from their father and mother, respectively. Both variants were predicted to be pathogenic based on bioinformatic analysis.
CONCLUSION
The two variants of the LARP7 gene, both were unreported previously, probably underlay the Alazami syndrome in this pedigree. Above finding has expanded the mutational spectrum of the LARP7 gene.
