ABSTRACT
Objective To explore the related factors of anemia during pregnancy and provide scientific evidence for the primary prevention of anemia during pregnancy.Methods The pregnant women (≤ 12 pregnant weeks) who received the first pregnancy care in a local medical institution in Hunan province from June 2013 to November 2014 were included in this cohort study,and for them anemia had been excluded by physical examination.Baseline survey and follow up till childbirth were conducted for them.A queue-based nested case-control study (1 ∶ 2) was conducted (380 pregnant women with anemia detected in this study as case group,760 pregnant women without anemia randomly selected and matched by age,habitual residence during pregnancy as control group.And t test,x2 test and logistic regression analysis were conducted to identify related factors of anemia during pregnancy.Results Multivariate logistic regression analysis indicated that low family annual income level (net income) (OR=2.08,95％CI:1.22-3.59),low educational level (OR=2.09,95％CI:1.22-3.59),pre-pregnancy perm/hair dye (OR=2.23,95％ CI:1.63-3.05),early pregnancy vomiting (OR=2.51,95％ CI:1.56-4.03) were the risk factors for anemia during pregnancy.Intake of vitamin and trace element supplements (OR=0.69,95％ CI:0.50-0.94),frequent meat,fish,shrimp,egg intakes (OR=0.68,95％CI:0.49-0.92),frequent soy milk,milk intakes (OR=0.51,95％CI:0.27-0.95) were the protective factors for anemia during pregnancy.Conclusion A number of factors,such as family annual income level,education level,poisonous and harmful material contact,pregnancy reaction,nutrition,are related to the incidence of anemia during pregnancy,it is necessary to take preventive measures to reduce the incidence of anemia during pregnancy.

ABSTRACT
OBJECTIVE: To study the protective efffects of Chailing Guiqi Decoction (CLGQD) combined with lumbrukinase on renal function in rats with adriamycin nephropathy. METHODS: Thirty-six SD rats were randomly divided into four groups: normal control group, untreated group, simvastatin-treated group and CLGQD -treated group. Adriamycin nephropathy was induced by intravenous injection with 5 mg/kg adriamycin. After seven-day treatment, quantitative measurement of 24-h urine protein was determined with trichloroacetic acid, and serum total protein (TP), albumin (Alb), total cholesterol (TC), triglycerides (TG), high-density lipoprotein (HDL), low-density lipoprotein (LDL), creatinine (Cr) and blood urea nitrogen (BUN) were assessed using automatic biochemistry analyzer. The pathomorphological changes of renal tissues were observed with light and electron microscopes. RESULTS: In the untreated group, the 24-h urine protein excretion, serum TC, TG, LDL, Cr and BUN were significantly higher than those in the normal control group (P<0.05 or P<0.01), while the serum TP, Alb, HDL were significantly lower than those in the normal control group (P<0.01). In the CLGQD-treated group, the 24-h urine protein excretion, serum TC, TG, LDL, Cr and BUN were significantly lower as compared with those in the untreated group (P<0.05 or P<0.01), while the serum TP, Alb and HDL were significantly higher as compared with those in the untreated group (P<0.05 or P<0.01). The pathomorphological findings of the renal tissues under the light microscope in the untreated group showed focal segmental glomerulosclerosis in a few of glomerulus, degenerated and swelled proximal tubular epithelial cells, proteins in cast formation in some renal tubules and scattered fibrosis in interstitial tissues of the kidney, while the electron microscope images showed the fusion of foot processes in glomerular epithelial cells. The pathomorphological changes in the CLGQD-treated group were slighter than those in the untreated group. CONCLUSION: CLGQD combined with lumbrukinase can reduce proteinuria, regulate lipid metabolism, protect renal function, and delay progressive renal damage in rats.
