ACC oxidase (ACO) is one of the key enzymes that catalyze the synthesis of ethylene. Ethylene is involved in salt stress response in plants, and salt stress seriously affects the yield of peanut. In this study, AhACO genes were cloned and their functions were investigated with the aim to explore the biological function of AhACOs in salt stress response, and to provide genetic resources for the breeding of salt-tolerant varieties of peanut. AhACO1 and AhACO2 were amplified from the cDNA of salt-tolerant peanut mutant M29, respectively, and cloned into the plant expression vector pCAMBIA super1300. The recombinant plasmid was transformed into Huayu22 by pollen tube injection mediated by Agrobacterium tumefaciens. After harvest, the small slice cotyledon was separated from the kernel, and the positive seeds were screened by PCR. The expression of AhACO genes was analyzed by qRT-PCR, and the ethylene release was detected by capillary column gas chromatography. Transgenic seeds were sowed and then irrigated with NaCl solution, and the phenotypic changes of 21-day-seedings were recorded. The results showed that the growth of transgenic plants were better than that of the control group Huayu 22 upon salt stress, and the relative content of chlorophyll SPAD value and net photosynthetic rate (Pn) of transgenic peanuts were higher than those of the control group. In addition, the ethylene production of AhACO1 and AhACO2 transgenic plants were 2.79 and 1.87 times higher than that of control peanut, respectively. These results showed that AhACO1 and AhACO2 could significantly improve the salt stress tolerance of transgenic peanut.

Objective:To analyze the correlation between simple thyroid nodule and blood lipid and glucose metabolism and iodine nutrition level.Methods:A cross-sectional study was conducted by collecting data of the population undergoing epidemiological investigation in Jinshan District, Shanghai from July to December 2015, to calculate the prevalence of thyroid nodules and analyze relevant functional indicators.Results:Simple thyroid nodules were detected in 603 subjects, with a prevalence of 22.6% (603/2 669). There were 358 female patients with simple thyroid nodules, with a prevalence rate of 26.9%, and 245 male patients with simple thyroid nodules, with a prevalence rate of 18.3%. The prevalence of simple thyroid nodule in female was higher than that in male, and the difference was statistically significant (χ 2=27.686, P<0.001). In addition, the prevalence of simple thyroid nodules increased with age (13.1% (92/704) and 20.2% (104/514) and 25.1% (145/578) and 24.4% (107/439) and 36.3% (98/270) and 34.8% (57/164), χ 2=83.872,P<0.001). In the ≤30 years group (8.0% (30/704) vs. 18.8% (62/331), χ 2=35.716, P<0.001), >30 to ≤40 years old group (14.1% (37/263) vs. 26.7% (67/251), χ 2=12.683, P<0.001), >60 to ≤70 years old group (26.2% (33/126) vs. 45.1% (65/144), χ 2=10.435, P<0.001), and the 70-year-old group (24.4% (21/86) vs. 46.2% (36/78), χ 2=8.521, P<0.001). The prevalence of simple thyroid nodules in males was lower than that in females. In the simple positive thyroid nodule group, Fasting blood glucose (5.12 (4.80, 5.69) and 5.02 (4.72, 5.48)), total cholesterol (1.24 (0.85, 1.86) and 1.13 (0.77, 1.76)), triglyceride (4.77 (4.09, 5.48) and 4.49 (3.92, 5.16)), low density lipoprotein((2.79 (2.26, 3.36) and 2.63 (2.19, 3.16)), and high density lipoprotein cholesterol (1.41 (1.18, 1.66) and 1.35 (1.13, 1.61)) were higher than those in the negative group ( U values were 554 818, 578 468, 535 622, 556 067 and 567 960, respectively, all P<0.01). The BMI index grade distribution of thyroid nodule positive group was higher than that of negative group, and the difference was statistically significant (3.7% (77/2 066), 50.1% (1 034/2 066), 32.4% (669/2 066), 13.8% (286/2 066), 3.2% (19/603), 43.6% (263/603), 38.1% (230/603), 15.1% (91/603), χ2=9.5201, P=0.023). The prevalence of simple thyroid nodules was significantly lower in the iodized salt group than in the non-iodized salt group (20.7% (436/2 102) vs. 29.5% (167/567), χ 2=19.376, P<0.001). The urinary iodine level in the positive thyroid nodule group was significantly lower than that in the negative group (148.4(100.2, 213.7) vs. 169.5(115.4, 241.75), U=545 129.5, P<0.001). After Logistic regression screening, age ( OR=1.57, 95% CI: 1.292-1.908, P<0.001), gender ( OR=1.278, 95% CI: 1.193-1.368, P<0.001), BMI grade ( OR=1.166, 95% CI: 1.022-1.330, P=0.022), total cholesterol ( OR=1.105, 95% CI: 1.005-1.214, P=0.040), iodized salt ( OR=0.689, 95% CI: 0.556-0.854, P=0.001) were independent influencing factors of thyroid nodule. Conclusion:The prevalence of simple thyroid nodules in Shanghai is relatively low. Age, sex, BMI level, total cholesterol and iodized salt are independent factors causing thyroid nodules. In addition, blood glucose level may also be related to the prevalence of thyroid nodules.

Objective To report the clinical outcomes of open reduction and internal fixation for capitellum fractures in adolescents.Methods From January 2010 to January 2015,14 adolescents with capitellum fracture were admitted to our department.They were 12 males and 2 females,aged from 12 to 16 years (13.7 years).By the Dubberley classification,we had 2 cases of type ⅠA,8 cases of type ⅡA,3 cases of type Ⅲ A and one of type Ⅲ B.We summarized their clinical characteristics and injury mechanisms.At the last follow-up,the therapeutic efficacy was assessed by the Mayo elbow function scores,and the ranges of motion of the elbow and forearm on the affected side were recorded.Results The 14 patients obtained an average follow-up of 12 months (from 6 to 18 months).All the cases achieved fracture union within 3 months,but malunion appeared in one.At the last follow-up,the ranges of flexion and extension of the affected elbow averaged 120.6° (from 110° to 135°),and the ranges of lateral rotation of the affected forearm averaged 160.3° (from 150° to 175°).According to the Mayo scores at the last follow-up,the elbow function was rated as excellent in 12 and as good in one.Mild traumatic arthritis occurred in 3 cases.Conclusions Capitellum fractures in adolescents are often Dubberley type A ones without a complicated fracture of the posterior condyle.Usually,the capitellum is impacted by the radial head in the process of elbow extension with valgus stress.After definite diagnosis,open anatomical reduction and reasonable and reliable internal fixation can result in good clinical results.

OBJECTIVETo screen fatty acid oxidation disorders (FAOD) in newborns in Zhejiang province.

METHODSA total of 1 861 262 newborns were screened for FAOD in Neonatal Screening Center of Zhejiang Province during January 2009 and December 2016. The blood samples from newborns were screened by tandem mass spectrometry, and diagnosis of FAOD was confirmed by urine organic acid measurement combined with genetic analysis. The prognosis and follow-up of patients with FAOD were also evaluated.

RESULTSOf 1 861 262 newborns screened, 121 cases of FAOD were diagnosed. Among 121 cases of FAOD, primary carnitine deficiency (PCD) was the most common type (=78, 64.5%), which was followed by short-chain acyl-CoA dehydrogenase deficiency (SCADD,=27, 22.3%), medium-chain acyl-CoA dehydrogenase deficiency (=5, 4.1%), multiple acyl-CoA dehydrogenase deficiency (MADD,=4, 3.3%), very long-chain acyl-CoA dehydrogenase deficiency (=3, 2.5%), carnitine palmitoyltransferase Ⅰ deficiency(=2, 1.7%)and carnitine palmitoyltransferase Ⅱ deficiency (CPTⅡD,=2, 1.7%). During 2-82 month follow-up, 15 patients were lost, 4 were dead (1 PCD, 1 MADD, and 2 CPTⅡD), and the remaining 102 subjects had normal intelligence and physical development without any clinical symptoms.

CONCLUSIONSPCD and SCADD are the most common FAODs in newborns in Zhejiang province. Most of FAOD patients are asymptomatic, and have normal growth and development after early intervention and management.

OBJECTIVETo analyze the results and follow up data of screening for newborn organic aciduria in Zhejiang province.

METHODSThe results and follow-up data of 1 861 262 newborns from Zhejiang province undergoing screening for organic aciduria during January 2009 and December 2016 were retrospectively analyzed. The acylcarnitine spectrum in urine samples was detected by tandem mass spectrum (MS/MS) and the positive patients were confirmed by urine gas chromatography mass spectrometry and/or gene analysis.

RESULTSNinety two cases of organic aciduria were confirmed with a prevalence of 1:20 200. Among 40 cases of methylmalonic academia (MMA), 13 (32.5%) were of MMA simple type and 27 (67.5%) were combined type. Genetic analysis showed 6 cases of MUT type and 1 case of CblB type out of 7 patients with MMA simple type, 10 cases of CblC and 1 case of CblF out of 11 patients with combined type, respectively. Six patients had propionic academia with a prevalence of 1:310 200, 7 had isovaleric academia (1:265 900), 6 had glutaric academia type 1 (1:310 200), 27 had 3-methylcrotonyl-CoA carboxylase deficiency (MCC, 1:68 900), 1 had 3-hydroxy-3-methylglutaric aciduria (1:1 861 300), 2 had β-ketothiolase deficiency (1:960 600), and 3 had biotinidase deficiency/holocarboxylase synthetase deficiency (1:620 400). Thirty-one patients had a disease onset at neonatal period, and 15 at post-neonatal period. Thirty-three patients had brain involvements or cranial imaging disorders. Three patients with MMA had kidney diseases or heomlytic uremic syndrome, and 3 had myocardial impairments. Twenty patients died during the follow-up.

CONCLUSIONSMMA is the most common newborn organic aciduria in Zhejiang province. Except MCC, most organic aciduria may lead to metabolism decompensation, complications or even death.
