Objective To explore the clinical value of prenatal screening by detecting α-fetoprotein(AFP),β-human chorionic gonadotrophin(β-HCG)and free estriol(u-E3)levels in the second trimester of pregnancy.Methods AFP,β-HCG and u-E3 were de-tected in 3 595 second trimester pregnant women by chemiluminescence.The risk value was calculated by combining with the factors of age,pregnant weeks,body weight,etc.Then the high-risk pregnant women were carried out the amniotic fluid cells chromosome karyotype analysis and B-ultrasonic examination.Results Among 3 595 pregnant women,the screening positive rates of Down′s syndrome(DS),Edward′s syndrome(ES)and neural tube defects(NTD)were 3.70%(133/3 595),0.11%(4/3 595)and 1.44%(52/3 595)respectively.In the prenatal screening,there were 189 cases of high risk pregnant women,among them 87 cases were per-formed the prenatal diagnosis of amniotic fluid cells chromosome karyotype analysis and B-ultrasonic examination,6 cases were defi-nitely diagnosed,in which 3 cases were DS,2 cases were NTD and 1 case was ES.Conclusion Prenatal screening is a non-invasive detection method and has the important clinical application value for avoiding the birth of DS,ES and NTD neonates.

Objective To study the effect of hydroxychloroquine (HCQ) on the suppressors of cytokine signaling (SOCS) in the kidney of MRL/lpr mice and evaluate the protection of HCQ on lupus nephritis.Methods Twenty-six rats were randomly divided into 3 groups:the control group which was consisted of 6 mice; the MRL/lpr group which was consisted of 10 mice; and the HCQ group which was consisted of 10.24-hour urinary protein level and anti dsDNA levels were tested.The expressions of SOCS-1 and SOCS-3 protein were determined by western blot.Analysis of variance was used to determine statistically significant differences between the two groups.A P value less than 0.05 was considered to be statistically significant.Results Compared with the control group,the levels of 24-hour urinary protein [(2 356.6±509.3) mg vs (440.3±90.1)mg] and anti ds-DNA (128.7±32.3 vs 14.9±1.4) were significantly increased in the MRL/lpr group,the expression levels of SOCS-1 and SOCS-3 protein were increased.After treated with HCQ,the levels of 24-hour urinary protein [(70.8±11.1) mg vs (2 356.6±509.3) mg] and anti-dsDNA (111.8±330.1 vs 128.7±32.3)were significantly decreased,the expression level of SOCS-1 and SOCS-3 protein decreased significantly (P＜ 0.05).Conclusion HCQ can inhibit SOCS expression in the kidney of lupus mice,reduce proteinuria and delay progression of immune disorders and lupus nephritis.

It has been reported that the level of antioxidants is lower in obese patients compared with that in normal weight subjects. Important antioxidants, vitamin E and ?-carotene, are lowered in obese adults and children, which may cause lipid super oxidation and are associated with atherosclerosis, coronary heart disease and myocardial infarction. Copper and zinc are trace elements that compose parts of enzymes such as CuZn-superoxide dismutase (CuZn-SOD) which can scavenge free radicals. Plasma copper and zinc levels are lowered in obese individuals, which may lead to abnormality in glucose metabolism.

A Review Many studies indicate that apoptosis is involved in the progression of congestive heart failure. At present, mechanisms that mitochondria regulates cell apoptosis is widely accepted.Cardiac myocytes have abundant mitochondria,which plays an important role in maintenance of cell physiological function. Recent studies find that cardiac energy metabolic shifts occur as a normal response to diverse physiologic and dietary conditions and as a component of the pathophysiologic processes which accompany cardiac hypertrophy, heart failure, and myocardial ischemia.Both clinical and experimental studies show that cardiac function can be improved and apoptosis is inhibited by intervention in energetic metabolism of myocytes.
