Six new 4＂-benzyloxyimino-4＂-deoxyavermectin B la derivatives were synthesized from avermectin Bla by the selective protection of C-5-hydroxy group, oxidation of C-4＂-hydroxy group, and deprotection followed by reaction with O-substituted hydroxylamine hydrochlorides. Their structures were confirmed by IR, 1H NMR, 13. NMR and MS. Insecticidal activities of the derivatives against Phopalosiphum pseudobrassicae, Spodoptera exigua and Pluteua xylosteua were evaluated.

Background： Fetal insulin hypothesis was proposed that the association between low birth weight and type 2.diabetes is principally genetically mediated. The aim of this study was to investigate whether common variants in genes CDKALI, HHEX, ADCY5, SRR, PTPRD that predisposed to type 2.diabetes were also associated with reduced birthweight in Chinese Han population.Methods： Twelve single nucleotide polymorphisms （rs7756992.rs109463.8 in CDKAL1, rsl 111875 in HHEA; rs3.13.0 in SRR, rs17584499 in PTPRD. rs1170806/rs9883.1}4/rs4678017/rs9881942.rs76413.4/rs67773.7/rs62.62.3.in ADCY5） were genotyped in 1174 unrelated individuals born in Peking Union Medical College Hospital from 192. to 1954 by TaqMan allelic discrimination assays, of which 645 had normal glucose tolerance, 181 had developed type 2.diabetes and 3.8 impaired glucose regulation. Associations of these 12.genetic variants with birthweight and glucose metabolism in later life were analyzed.Results： Birthweight was inversely associated with CDKAL 1-rs 109463.8 （β = -41 g [95% confidence interval [ci]： -80, 3., P= 0.03.）, common variants both associated with increased risk of impaired glucose metabolism and decreased insulin secretion index later in life. After adjusting for sex, gestational weeks, parity and maternal age, the risk allele of CDKAL1-rs7756992.was associated with reduced birthweight （β = 3. g [95% ci： -72. -0.2., P = 0.048）. The risk allele in SRR showed a trend toward a reduction ofbirthweight （P =0.085）. Conclusions： This study identified the association between type 2.diabetes risk variants in CDKAL 1 and birthweight in Chinese Hart individuals, and the carrier of risk allele within SRR had the trend of reduced birthweight. This demonstrates that there is a clear overlap between the genetics of type 2.diabetes and fetal growth, which proposes that lower birth weight and type 2.diabetes may be two phenotypes of one genotype.

BACKGROUND The efficacy and safety of proprotein convertase subtilisin/kexin type 9(PCSK-9) inhibitors were confirmed by several clinical trials, but its effectiveness in routine clinical practice in China has not been evaluated. This study aims to describe the real world effectiveness of PCSK-9 inhibitors combined with statins compared with statins-based therapy among patients with very high risk of atherosclerotic cardiovascular disease(ASCVD).METHODS This is a multi-center observational study, enrolled patients from 3.0}hospitals who underwent percutaneous coronary intervention(Pci) from January to June in 2.19. There are 453.patients treated with PCSK-9 inhibitors combined with statins in PCSK-9 inhibitor group and 2.610 patients treated with statins-based lipid lowering therapies in statins-based group.
