OBJECTIVETo observe the effect of low molecular weight heparin calcium (LMWHC) combined Compound Danshen Injection (DI) on nephrotic syndrome patients with early onset severe preeclampsia.

METHODSTotally 80 nephrotic syndrome patients with early onset severe pre-eclampsia were randomly assigned to four groups voluntarily, i.e., Group A (22 cases, treated by magnesium sulfate), B (19 cases, treated by magnesium sulfate plus LMWHC), C (21 cases, magnesium sulfate plus DI), D (18 cases, magnesium sulfate plus LMWHC and DI). Umbilical arterial S/D ratios, amniotic fluid index (AFI), prolonged gestational age, placenta weight, neonatal weight, and Apgar score were compared among the four groups.

RESULTSCompared with before treatment in the same group, umbilical arterial S/D ratios decreased in the four groups (P <0. 05). AFI decreased in Group A, while it increased in Group B, C, and D (P<0. 05). Compared with Group A at the same time point, umbilical arterial S/D ratios decreased, and AFI increased in Group B, C, and D (P <0. 01 , P <0. 05). Prolonged gestational age and neonatal weight were increased in Group B, C, and D (P <0. 01, P <0. 05). Placenta weight were increased in Group B and D (P <0. 05). Apgar scores at 1 and 5 min were improved in Group D (P <0. 05). Compared with Group B and C at the same time point, umbilical arterial S/D ratios decreased, and AFI increased in Group D (P<0. 05). Compared with Group B, prolonged gestational age and placenta weight were decreased in Group C, but prolonged gestational age and placenta weight were increased in Group D (P <0.05). Compared with Group C, prolonged gestational age, placenta weight, and neonatal weight were increased in Group D (P <0. 05).

CONCLUSIONTreatment of nephrotic syndrome patients with early onset severe pre-eclampsia by LMWHC combined DI could prolong gestational ages, obviously improve prenatal outcomes, with better effect obtained than using any of them alone.

Objective: To investigate the mechanism of fructose-induced monocyte chemoattratant protein-1(MCP-1) production in HK-2 cells. Methods: The HK-2 cells were divided into fructose incubated (1, 5 and 10 mmol/L) group, fructose and ketohexo-kinase inhibitor (KHK-IN) coincubation (fructose 5 mmol/L, KHK-IN was 12, 100 and 1000 nmol/L, respectively) group, uric acid incubation (5, 15 and 50 mg/dL) group, fructose and allopurinol co-incubation (fructose 5 mmol/L, allopurinol were 0.01, 0.1 and 0.5 mmol/L) group, uric acid and allopurinol co-incubation (uric acid 50 mg/dL, allopurinol respectively 0.01, 0.1and 0.5 mmol/L) group, H2O2 incubation (0.1 and 0.3 mmol/L) group, fructose and N-acetylcysteine (NAC) coincubation (fructose 5 mmol/L, NAC respectively 5, 10 and 50 mmol/L) group, and uric acid and NAC co-incubation (uric acid 50 mg/dL, NAC was 5, 10 and 50 mmol/L, respectively) group. The quantitative PCR method and Western blotting method were used to observe the expression of MCP-1 mRNA and protein. The effects of fructose and uric acid on the production of ROS in HK-2 cells were observed by using a fluorescent probe. Results: Fructose doseand time-dependently induced MCP-1 gene transcription and protein production in HK-2 cells, which could be blocked by the ketohexo-kinase blockers. Exogenous uric acid induced MCP-1 production in HK-2 cells. Allopurinol inhibited fructose, but not exogenous uric acid-induced MCP-1 expression. Both fructose and uric acid induced ROS generation. Incubation with H2O2 promoted MCP-1 production in HK-2 cells. NAC completely inhibited MCP-1 production induced by fructose and H2O2. Conclusion: Catalyzed by the ketohexo-kinase, fructose resultes the production of MCP-1 through uric acid and reactive oxygen species.

In order to explore the dormancy physiological and biochemical mechanism of Paris seeds, the seed embryo growth courses, and the dynamic change of 5 enzymes, include SOD, POD, CAT, MDH, G-6-PDH were measured during variable temperature stratification. The results indicated that Paris seeds embryo grew quickly after 40 d in warm-stratification (18 ± 1) °C, at the meantime the metabolic activity was significantly strengthened. These facts showed that Paris seeds turned into physiological after-ripening process. After 60-80 d, the morphological embryo after-ripping process basically completed, and the following cold-stratification (4 ± 1) °C furthered Paris seed to finish physiological after-ripening. After 40 d, the activity of MDH decreased while G-6-PDH increased significantly. This showed that the main respiratory pathway of seed changed from TCA to PPP, which benifited breaking seed dormancy. In the whole period of stratification process, the activity variation of SOD and CAT was insignificantly and the activity of POD was enhanced significantly after shifting the seed in cold stratification process. This showed that SOD, CAT had no direct effects on breaking Paris seed dormancy but keeping the seed vigor, while the POD might involve in the process of Paris seed dormancy breaking.

Mitochondrial respiratory chain deficiency is a common cause of mitochondrial disease in children. This study aimed to review the clinical, enzymatic and genetic characteristics of a Chinese boy with progressive intrahepatic cholestasis due to mitochondrial respiratory chain complex I deficiency. The boy developed diarrhea from the age of 13 months, followed by progressive body weight loss, jaundice and weakness. His urine organic acids, blood amino acids and acylcarnitines profiles were normal. Mitochondrial respiratory chain complexes I to V activities in peripheral leukocytes were measured using spectrophotometric assay. Complex I activity was reduced. 5821G>A mutation was indentified by gene sequencing on tRNA-cys of mitochondrial gene in the patient and his mother. Vitamin supplements, liver protection, antibiotics and plasma infusion were not effective in the patient. Unfortunately, the boy died at the age of 17 months. Mitochondrial respiratory chain complex I deficiency is the most common mitochondrial respiratory chain disorder. This was the first case of intrahepatic cholestasis due to complex I deficiency confirmed by mitochondrial respiratory chain enzyme activity assay and gene analysis in China. It was concluded that mitochondrial hepatopathy is one of major causes of metabolic hepatopathy. Biochemical assay, mitochondrial respiratory chain complex activities assay and genetic analysis are crucial for the etiological diagnosis of metabolic hepatopathy.

This study was amid to construct the pharmacophore model of L-type calcium channel antagonist in the application of screening Drugbank and TCMD. This paper repositions the approved drugs resulting from virtual screening and discusses the relocation-based drug discovery methods, screening antihypertensive drugs with L-type calcium channel function from TCMD. Qualitative hypotheses wre generated by HipHop separately on the basis of 12 compounds with antagonistic action on L-type calcium channel expressed in rabbit cardiac muscle. Datebase searching method was used to evaluate the generated hypotheses. The optimum hypothesis was used to search Drugbank and TCMD. This paper repositions the approved drugs and evaluates the antihypertensive effect of the chemical constituent of traditional Chinese medicine resulting from virtual screening by the matching score and literature. The results showed that optimum qualitative hypothesis is with six features, which were two hydrogen-bond acceptors, four hydrophobic groups, and the CAI value of 2.78. Screening Drugbank achieves 93 approved drugs. Screening TCMD achieves 285 chemical constituents of traditional Chinese medicine. It was concluded that the hypothesis is reliable and can be used to screen datebase. The approved drugs resulting from virtual screening, such as pravastatin, are potentially L-type calcium channels inhibitors. The chemical constituents of traditional Chinese medicine, such as Arctigenin III and Arctigenin are potentially antihypertensive drugs. It indicates that Drug Repositioning based on hypothesis is possible.

OBJECTIVETo explore the effect and mechanism of vitamin D supplementation in early life on rat asthma model.

METHODThirty two sex-mature, female Wistar rats were randomly divided into a control group (n = 8), a low dose group (n = 8), a medium dose group (n = 8) and a high dose group (n = 8). From the seventh day of pregnancy on, the rats in each group were given different doses of vitamin D by intragastric administration, until the offspring rats were 21 days old. The rats in the control group were fed with DMSO-PBS. After the offsprings were weaned, 8 rats were randomly selected from each group. The number of male and female rats was equal. The rats were sensitized to ovalbumin (OVA) and challenged with aerosol OVA to establish the asthma model. The lung tissues were examined for pathologic changes after HE staining. ELISA was used to determine the concentrations of IL-10 in serum and BALF. Immunohistochemical staining methods were used to measure the expression of intercellular adhesion molecule-1 (ICAM-1) in lung tissues.

RESULT(1) Pathologic changes of lung tissues: compared with the control group, light microscope (LM) showed that eosinophil cells infiltration and the airway inflammation decreased in the low dose and medium dose groups, but increased in the high dose group. (2) The concentrations of IL-10 in serum and BALF: In serum, compared with the control group [(18.7 +/- 4.7) pg/ml], the concentrations of IL-10 in the low dose group [(30.2 +/- 2.8) pg/ml, P < 0.05] and the medium dose group [(51.5 +/- 6.6) pg/ml, P < 0.05] were significantly increased. And the IL-10 level of medium dose group was higher than that of the low dose group (P < 0.05). In BALF, compared with the control group [(59.1 +/- 14.4) pg/ml], the concentrations of IL-10 in the medium dose group [(90.0 +/- 14.3) pg/ml, P < 0.05] was significantly increased. There were no significant changes in the low dose group [(58.1 +/- 3.4) pg/ml, P > 0.05], whereas in the high dose group [(45.3 +/- 6.5) pg/ml, P < 0.05] the level significantly decreased. (2) The expression of ICAM-1 in lung tissues: compared with the control group, there were no significant changes in the low dose group (P > 0.05). The expression of ICAM-1 was significantly decreased in the medium dose group (P < 0.05). In the high dose group, the expression of ICAM-1 was significantly increased (P > 0.05).

CONCLUSIONAdequate intervention with 1,25(OH)2D3 in the early life could alleviate the inflammation in the lung tissues, reduces eosinophil cell infiltration in rat asthma model. However, overdose might play a detrimental role. Its mechanism may be associated with the effect of 1,25(OH)2D3 on IL-10 secretion and the expression of ICAM-1.
