We present the results of determining Zn,Cu,Fe,Mn,Ca and Mg in the serum samples of 36 cases and hair samples of 42 cases.Comparing the patients of trophoblastic tumor with the local normal pregnant women in the same period,we found that in the patients' serum the amount of Zn decreased,and the amount of copper and the ratio of Cu/Zn increased evi- dently.They developed or went down along with the patients being worse or better.In the pa- tients' hair the amount of Zn decreased obviously and the ratio of Cu/Zn increased.The re- sults indicated that the determination of Zn in the seum and hair would be of great value in finding and diagnosing the disease early and the determination of Cu,Zn and the ratio of Cu/Zn with CP and HCG would provide a basis for the state of illness and it's prognosis.It was noted that the amount of manganese in the serum and hair of the patients was distinctly higher than those of the contrast.It provided an experimental basis for the prevention, diagnosis,treatment and prognosis of trophoblastic tumor.

Objective To investigate the effect of Interleukin(IL)-18,IL-12 and tumor necrosis factor-α(TNF-α)in hepatic injury in intrahepatic cholestasis of pregnancy(ICP).Methods Sixty-two cases of ICP patients(ICP group),30 cases of normal pregnant women(control group)and 30 cases of hepatitis B(HBV) women (hepatitis group) were recruited. Serum IL-18, IL-12 and TNF-α were examined by ELISA. Serum alanine aminotransferase (ALT) and aspartate aminotransferase (AST) were examined by automatic biochemical analysis instrument. Results ( 1 ) In hepatitis group, serum concentrations of IL-18,IL-12 and TNF-α were (256±51 ) ng/L, ( 122±96) ng/L and (207±3) ng/L; serum levels of ALT and AST were(363±174) U/L and (359 ±237) U/L, respectively. In ICP group, serum concentrations of IL18, IL-12 and TNF-α were (72±32) ng/L, (42 ±28) ng/L and (48±14) ng/L; serum levels of ALT and AST were (201 ±128) U/L and ( 132±87) U/L, respectively. While in control group, serum concentrations of IL-18, IL-12 and TNF-α were (43 ± 13) ng/L, ( 10±3) ng/L and (33±9) ng/L; serum levels of ALT and AST were (13 ~ 4) U/L and (15 ± 3) U/L, respectively. Serum IL-18, IL-12, TNF-α, ALT and AST levels in hepatitis group were significantly higher than those in ICP group and control group ( P ＜0. 05 ).Serum IL-18, IL-12, TNF-α, ALT and AST levels in ICP group were significantly higher than those in control group(P ＜ 0. 05 ). (2) In severe ICP subgroup, serum concentrations of IL-18, IL-12 and TNF-α were (81 ±32) ng/L, (50 ±25) ng/L and(50 ± 14) ng/L; serum levels of ALT and AST were (269 ± 111 ) U/L and (181±73) U/L In mild ICP subgroup, serum concentrations of IL-18, IL-12 and TNF-α were (48 ±18 ) ng/L, (17 ± 4 ) ng/L and (40 ± 10 ) ng/L; serum levels of ALT and AST were (87±46) U/L and (50 ±21 ) U/L, respectively. Serum IL-18, IL-12, TNF-α, ALT and AST levels in severe ICP subgroup were significantly higher than those in mild ICP subgroup and control group (P ＜ 0. 05). And serum ALT and AST levels in mild ICP subgroup were significantly higher than those in control group(P ＜0. 05). (3) There were 16 cases with preterm birth (50%, 16/32 ) and 10 cases with meconium-stained amniotic fluid( 31%, 10/32 ) in severe ICP subgroup, significantly higher than those in mild ICP subgroup ( P＜ 0. 05 ), which contained 2 preterm births ( 7%, 2/30) and 1 meconium-stained amniotic fluid (3%, 1/30). While in control group, the numbers were 1(3%, 1/30)and 1(3%, 1/30),respectively. As for the cases of neonates whose 1 minute Apgar score were not more than 7, there were 2 cases, 1 case and 1 case in severe ICP subgroup, mild ICP subgroup and control group, respectively,which showed no significant difference(P＞ 0. 05). Conclusion Serum IL-18, IL-12 and TNF-α may be involved in the process of hepatic injury of ICP.

Using Isopropyl amine (0.003 mol/L), p-methyl-phenol (0.03 mol/L) and methanol (1 mol/L) for simulating amino groups, phenol groups and hydroxyl groups in silk fibroin respectively, the reaction rate of different nucleophilic groups in silk with monochlorotriazine reactive dye was studied at various temperature and pH by high performance liquid chromatography. It was found that the overall reaction rate of dyes′ phenolysis was by far higher than that of ammonolysis and alcoholysis on the conditions of 70-95 ℃ and pH=8-10. The phenolysis overall reaction rates of C.I. reactive red 24 and C.I. reactive orange 2 were 8.5 and 12.5 times of their ammonolysis′, and 23 and 50 times of their alcoholysis′ in the term of pH 9 and 95 ℃. The phenolysis efficiencies of those two dyes were 47.4 and 96.3, the ammonolysis efficiencies were 4.6 and 6.9, and the isopropyl amine, p-methyl-phenol and methanol to simulate the silk fibroin, the reaction selectivity between the monochlorotriazine reactive dyes and nucleophilic groups in silk fibroin was investigated. It was deduced that monochlorotriazine reactive dyes are suitable for dyeing silk on the conditions of about 85 ℃ and pH=8-9, and under this condition, phenol groups are the major groups in silk dyeing with monochlorotriazine reactive dyes, amino groups are the minor groups, and the contributions of hydroxyl groups can be neglected.
