ABSTRACT
Borneol is a major component of many medicinal plant essential oils, as well as a popular traditional Chinese medicine. This essay collects the results of the latest domestic and foreign studies, and summarizes and analyzes its activity and reaction mechanism on analgesia, putridity elimination and flesh regeneration, and repair of damaged cells. Moreover, it proposes problems concerning borneol during medical studies, providing support for the in-depth study and exploration of efficacies of precious traditional Chinese medicines as well as the effective utilization and development of innovative medicines.

<p><b>OBJECTIVE</b>Recent studies have found that the variation of G894T on the region of T786C and 7th exon promoted by endothelial nitric oxide synthase (eNOS) gene is associated with cardiovascular disease. This research explored possible correlations between eNOS gene polymorphisms and orthostatic intolerance (OI) in children through linkage disequilibrium analysis between eNOS genes T786C and G894T and OI.</p><p><b>METHODS</b>PCR, Macrorestriction Map and other molecular biotechnology were used to determine the genotypes of eNOS/T786C and G894T in 60 OI probands and their parents. Correlation analysis and transmission disequilibrium test (TDT) between T786C, G894T and OI were performed.</p><p><b>RESULTS</b>There was linkage disequilibrium of eNOS/T786C and G894T gene polymorphisms in the occurrence of childhood OI (P<0.05).</p><p><b>CONCLUSIONS</b>eNOS genes T786C and G894T may be associated with the pathogenesis of OI.</p>

Objective To establish a rat model of pulmonary hypertension induced by left-to-right shunt and explore the influence of high pulmonary blood flow on pulmonary vascular collagen remodeling.Methods Abdominal aorta and inferior vena cava shunting was produced in rats. Pulmonary artery meanpressure (PAMP) of each rat was measured by using a right cardiac catheterization.Pulmonary artery collagen Ⅰ and Ⅲ were detected using immunohistochemisty.Results After 11 weeks of shunting the Qp/Qs was 3.3∶1.0,indicating a large shunt. Pulmonary artery mean pressure was increased as compared with controls[(23.0?0.9) mm Hg vs (15.7? 1.1) mm Hg,P
ABSTRACT
Objective To explore the gene expression of human telomerase reverse transcriptase (hTERT)in childhood acute non- lymphocytic leukemia (ANLL) and its clinical implication. Methods Expression of hTERT mRNA was detected in HL - 60 leukemia cell line, 14 ANLL children and 11 healthy children by reverse transcriptase- polymerase chain reaction (RT- PCR). Results hTERT gene was expressed in HL-60 cell line, ANLL children (11/14) and healthy children (2/11). The expression of hTERT gene was observed in all subtypes of ANLL. Furthermore, there were statistically significant differences in expression levels of hTERT gene between children with ANLL and healthy children (t = 5.034 P = 0). Conclusions The up - regulation of gene expression of hTERT may play a very important role in the progression of children ANLL. The detection of hTERT expression may be a useful additional method for monitoring the state of illness.
