There is immense interest in the long-chain polyunsaturated fatty acids(LC-PUFAs) on account of their health-beneficial properties.There has been considerable interest in the production of LC-PUFAs in transgenic plants to provide a cheap,sustainable and clean source of these fatty acids.Several main LC-PUFAs,their roles and metabolic pathway in plant are introducedbriefly,progresses on biosynthesis of LC-PUFAs in transgenic plant are reviewed,and strategies for improving the yields of LC-PUFAs in plant are also discussed.

To evaluate the efficacy and safety of limbal relaxing incision ( LRl) for correcting corneal astigmatism during implantable collamer lens ( lCL) surgery.METHODS:A total of 185 eyes of 105 patients with high myopia and corneal keratometric astigmatism were included in the study. lCL surgery with concomitant relaxing incision was performed in 105 eyes of 60 patients in LRls group ( Group A) . Eighty eyes of 45 patients only underwent lCL surgery were in control group ( Group B) . All patients undergone ophthalmic examination that included uncorrected visual acuity ( UCVA ) , best -corrected visual acuity ( BCVA ) , Pentacam analysis system to observe the changes of corneal astigmatism before and 1wk, 1 and 3mo after surgery.RESULTS: Respectively comparing UCVA between two groups in 1 and 3mo postoperatively, the P values were considered statistically significant ( P < 0. 05 ). But, respectively comparing BCVA between two groups in 1wk, 1 and 3mo postoperatively, the P values were considered no statistically significant ( P > 0. 05 ). Preoperative corneal astigmatism was 1. 52 ± 0. 55D in group A and 1. 48 ± 0. 57D in group B, there was no statistically significant difference (P>0. 05). One week postoperatively, the astigmatism was 0. 55 ± 0. 41D in group A and 1. 20 ± 0. 48D in group B. One month postoperatively, the astigmatism was 0. 60 ± 0. 38D in group A and 0. 93 ± 0. 47D. Three months postoperatively, the astigmatism was 0. 51 ± 0. 32D in group A and 0. 96 ± 0. 40D in group B. The difference between the two groups were statistically significant ( P<0. 05 ). The difference value of corned astigmatism before surgery and 1wk, 1 and 3mo after surgery had statistical significance ( P<0. 05). ln LRls group, at preoperative and postoperative time points, the average corneal astigmatism changes were also considered statistically significant difference (P<0. 05). CONCLUSlON: LRls performed during lCL surgery appeared to be an effective and safer procedure to reduce pre-existing corneal astigmatism and improve UCVA as well as the visual quality.

Many unusual fatty acids present in the seed oils of non-food plants are modified at the ?12 position either by the addition of epoxy or hydroxy groups or by the formation of triple (acetylenic) bonds or conjugated double bonds. The introduction of these functionalities into C18 fatty acids is catalyzed by a family of divergent forms of the fatty-acid ?12-desaturase (FAD2) enzyme. Genes encoding these enzymes have now been cloned from a variety of organisms and expressed in transgenic oilseeds. However,the accumulation of the intended fatty acids in transgenic plants has been relatively disappointing,and the mechanisms of these unusual fatty acids biosynthesis and transferring from phosphatidylcholine into storage triacylglycerols still need to be elucidated.

Objective:To study the change of immunological response and cell proliferation in breast tissues augmented by polyacrylamide hydrogel injection(PHI).Methods:The expression of CD68,CD25 and PCNA in 20 breast tissues with indurations,12 without indurations after breast augmentation by PHI,and 10 normal breast tissues was examined by immunohistochemistry P-V6000; analysis was also done by H-E staining.Results:Hyperplasia of fibrous tissue and infiltration of inflammatory cells and macrophages were found in the breast and adjacent tissues 3-8 years after PHI.Positive cells of CD68,CD25 and PCNA hardly existed in the normal tissues,but the breast tissues around the polyacrylamide hydrogel had many positive cells of CD68 and PCNA,especially in cases with indurations;there were significant differences between the 3 groups(P

Neuronal α4β2 nicotinic acetylcholine receptors (nAChRs) are the most widespread subtypes in central nervous system, α4β2 nAChRs mainly exist in procerebrum, parietal lobe cortex, temporal lobe cortex, hippocampus, basal ganglion and cerebellum. Researches on gene knock-out mice have demonstrated that α4β2 receptors participate in the development, aging, neuron survival, pain, and learning and memory, and are also involved in gamma-aminobutyric acid release and dopaminergic function. Studies have disclosed that α4β2 nAChRs relate to the development of variety of neurological diseases, including pain, Alzheimer's disease and Parkinson's disease.
