Chinese Journal of Biochemical Pharmaceutics 2017;37(9):393-394
Objective To investigate the pregnancy and operation of uterine fibroids during pregnancy. Methods The clinical data of 70 cases of pregnancy complicated with uterine fibroids undergoing cesarean section were analyzed retrospectively. The patients without uterine myoma underwent cesarean section were selected as the control group. The complications of pregnancy (abortion rate, premature delivery rate, myoma degeneration and abnormal fetal position) were compared; and the cesarean section bleeding volume, operation time, postoperative exhaust time and hospitalization time were compared. Results The two groups of pregnancy threatened abortion rate, preterm labor rate was statistically significant (P<0.05); the two groups the incidence of fetal abnormalities was not statistically significant. There was no significant difference between the two groups in the average intraoperative blood loss, operation time, postoperative exhaust time and hospital stay. Conclusion Pregnancy associated with uterine fibroids increases the incidence of pregnancy complications, but cesarean myomectomy is safe and feasible.

A method was developed for the simultaneous determination of 17 characteristic ingredients of plant extracts, including paeoniflorin, hydroxysafflor yellow A, calycosin_7_glucoside ferulic acid, etc. , in hair growth cosmetics using ultra high performance liquid chromatography ( UPLC ) . Different cosmetic samples were extracted by ultrasonic_assisted extraction with the solvent of methanol/water (4∶1, V/V) solution. After demulsified by the addition of appropriate amount of NaCl and high speed centrifugation, the supernatant was transferred and analyzed with UPLC. The separation was conducted on a Waters reversed phase column of ACQUITY UPLC CSH C18(50 mm×2. 1 mm, 1. 7μm), and the mobile phases were methanol and the solution of 0. 05% phosphate in water. The detection was performed with a photodiode_array ( PDA) detector. The linear range was 0 . 2-25 mg/L with correlation coefficients higher than 0 . 999 . The limits of detection were within 0. 3-1. 5 mg/kg, and the limits of quantification were from 1. 0 to 4. 0 mg/kg. The average recoveries of 17 characteristic ingredients were within 93 . 5%-105 . 0%, with the intra_and inter_day precision ( n=6 ) less than 4. 6%. This method was simple, rapid, with good_repeatability, and had been applied to the analysis of real samples.

In this study, metabolism of nobiletin in rats was studied using ultra-performance liquid chromatography coupled with tandem mass spectrometry (UPLC-MS/MS). As a result, seven major metabolites were found in bile, urine and serum of rats. Three phase I products were assigned to be demethyl and di-demethyl products, and other four phase II products were assigned to be glucuronic and sulfonic conjugates. The four phase II metabolites were reported for the first time. Among the metabolites found in the present study, the glucuronic conjugates of demethyl-nobiletin played a predominant role in the metabolic pathway, indicating that its potential role for glucuronidation-related factors, such as gene polymorphism, drug-drug interaction, etc., in changing the active and toxic effect of nobiletin and that it should be paid more attention in further development.

Objective To explore the value of DWI ADC in the diagnosis of hepatic ischemia reperfusion injury (IRI) at 3.0 T and investigate the mechanism by comparison with liver enzyme and pathological findings. MethodsForty-two New Zealand white rabbits were divided randomly into ( n = 6,each) six IRI groups by rank sum test. The IRI animals underwent left lobar ischemia for 60 min and were reperfused 0. 5 h, 2. 0 h, 6. 0 h, 12. 0 h, 24. 0 h and 48. 0 h later. One Sham operative group underwent laparotomy without liver ischemia. T2 WI, T1 WI, DWI and contrast-enhanced T, WI were performed with 3.0 T magnetic resonance imaging scanner in each group respectively. For DWI, b-values of 20, 50, 100,200,300,400,500 and 600 s/mm2 were used respectively. Blood samples were taken to detect the levels of serum alanine aminotransferase (ALT) and aspartate aminotransferase (AST) at different time points. Liver samples were examined histologically after MRI scanning. One-way analysis of variance (ANOVA) was used to determine differences, followed by LSD-t test for multiple comparisons. ResultsOverall, ADC decreased markedly at the early IRI phase ( 0. 5 h), drastically increased in the 2.0 h group, and then ascended slightly from 6. 0 h to 48.0 h after reperfusion, except for a transient decrease at the time point of 24. 0 h. When b values were 20, 50, 100,200 and 300 s/mm2, the ADC values in the Sham group were (3.47 ±0.53) × 10-3, (3.11 ±0.39) ×10-3, (2.87 ±0.19) ×10-3, (2.56 ±0.37) × 10-3 and (1.95 ±0.33) ×10-3mm2/s, (2.63±0.31)±10-3, (2.47±0.32) ×10-3, (2.12±0.38) ×10-3, (2.01±0.51) ×10-3and (1.61 ±0.17) ×10-3mm2/s in the 0.5 h group, (2.72 ±0.09) ×10-3, (2.51±0. 11) ×10-3, (2.28 ±0.30) ± 10-3, (1.96 ±0. 14) × 10-3 and (1.58 ±0. 17) × 10-3mm2/s in the 24.0 h group, respectively. ADC of 0. 5 h and 24. 0 h groups were significantly lower than that of Sham group (P<0.05) when b value was under 300 mm2/s.In the Sham, 0.5 h, 2.0 h, 6.0 h, 12.0 h,24.0 h and 48. 0 h IRI groups, they were (80±8), (181 ±34), (413 ±62), (474 ±83), (424 ±41 ),(332 ±41 )and(302 ±39) U/L for the levels of ALT,and (79 ± 10), (454 ±55), (547 ±72), (607±31 ), (649 ±79), (785 ±49) and ( 1526 ± 167) U/L for the AST respectively. The levels of AST and ALT in IRI groups were significantly higher than those in the Sham group ( P < 0. 01 ).Histological findings showed diffuse hepatocytes swelling and erythrocytes depositing in the hepatic sinusoids, portal area, central venous and arterials at the initial phase.With the injury aggravated, inflammatory cell infiltration,hepatocyte nuclear condensation of apoptosis, sinusoidal dissociation and coagulation necrosis developed eventually. Conclusion 3.0 T DWI can monitor the pathological process of rabbit liver ischemia reperfusion injury dynamically, and provides a feasible imaging modality for clinical diagnosis and treatment.
