6. Progress on Drug-induced Pulmonary Arterial Hypertension
Chinese Pharmaceutical Journal 2019;54(3):170-174
Pulmonary arterial hypertension (PAH) is characterized hemo-dynamically by the presence of pre-capillary pulmonary hypertension, defined by a pulmonary artery wedge pressure (PAWP) ≤15 mmHg and a pulmonary vascular resistance(PVR)>3 wood units (WU). According to the current classification, PAH can be associated with exposure to certain drugs or toxins such as anorectic agents, amphetamines, or selective serotonin reuptake inhibitors. The improvement in awareness and recognition of drug-induced PAH (DIPAH) have allowed the identification of more drugs associated with an increased risk for induction of PAH. The supposed mechanism is the increase of the serotonin level or activation of serotonin receptors that have been demonstrated to promote the growth of pulmonary artery smooth muscle cells and cause progressive obliteration of pulmonary vascular. DIPAH remains a rare complication, which may be associated with individual susceptibility, and further studies are needed to identify patients at risk of DIPAH.

ObjectiveTo establish the reference value of inhibin-A in the serum of pregnant women with gestational age from 15 to 20+6 weeks in Guangdong province,and assess the efficiency of inhibin-A and quadruple test in Down syndrome screening.Methods A total of 2802 singleton pregnancies receiving triple test screening in Guangzhou Women and Children's Medical Center from March 2008 to December 2010 were included in this study.Inhibin-A was measured by automatic enzyme-linked immunosorbent chemiluminescence assay. The concentration of inhibin-A was expressed as multiples of the median (MoM),and adjusted with maternal weight and gestational age.Parameters of SURUSS were used to recalculate the risk of Down syndrome.The efficacy of single marker and combination were evaluated by receiver operating characteristic curve and the area under the curve. Results(1) In normal singleton pregnancies,the median concentration of inhibin-A was 286.60,267.10,249.10,243.40,242.30 and 256.60 pg/ml respectively for each week of gestational age from 15 to 20+6 weeks.The distribution of inhibin-A in each gestational week was relatively stable.The mean concentration [(852.83±370.04) pg/ml] and MoM (2.82) of inhibin-A in twelve pregnant mothers with Down syndrome fetuses were significantly higher than those without [(293.28±149.46) pg/ml (t=5.37,P<0.05) and 1,respectively].(2) The detection rate was 83.3% (10/12) by using the quadruple test including free human chorionic gonadotropin-β,alphafetoprotein,unconjugated estriol and inhibin-A at false positive rate of 5.8%; while when the detection rate of triple test including alpha-fetoprotein,free human chorionic gonadotropin-β and unconjugated estriol was 83.3%,the false positive rate was 7.7%.When the false positive rate was set to 5.0%,the area under the curve of inhibin-A,alpha-fetoprotein,free human chorionic gonadotropin-β and unconjugated estriol was 63.7%,20.5%,46.1% and 4.8%,respectively,and the relative area under the curve of routine triple test and quadruple test was 45.5% and 63.1%,respectively.ConclusionsInhibin-A is suggested to be the most effective marker used for secondtrimester screening,which could be used for second trimester Down syndrome screening in Chinese population combined with existing three markers.

Applications of network pharmacology are increasingly widespread and methods abound in the field of drug development and pharmacological research. In this study, we choose rosiglitazone compound as the object to predict the targets and to discuss the mechanism based on three kinds of prediction methods of network pharmacology. Comparison of the prediction result has identified that the three kinds of prediction methods had their own characteristics: targets and pathways predicted were not in accordance with each other. However, the calcium signaling pathway could be predicted in the three kinds of methods, which associated with diabetes and cognitive impairment caused by diabetes by bioinformatics analysis. The above conclusion indicates that the calcium signaling pathway is important in signal pathway regulation of rosiglitazone compound, which provides a clue to further explain the mechanism of the compound and also provides a reference for the selection and application of methods of network pharmacology in the actual research.

9.Studies on the cell growth, differentiation and terpene lactone accumulation in Ginkgo biloba cell suspension cultures.
Chinese Journal of Biotechnology 2004;20(3):445-449
To provide supports for Ginkgo biloba cell engineering for production of Terpene lactones (Ginkgolides and bilobalide), the cell suspension were established from calli induced from zygote embryos and stems of 30-day-old seedlings respectively. The relationship between cell growth, differentiation and the terpene lactone accumulation in these suspension cultures were investigated. HPLC determination indicated that, the ginkgolide B was found in the embryo derived cell suspension cultures at 0.044% of cell dry weight, and this result was the first time reported in this study. The accumulation of terpene lactone in the suspension cultures derived from both the embryo and seedling stems are effected by the level of the cell differentiation. The ginkgolide B was only found in small cell aggregates in the size smaller than 2mm, and the highest level of ginkgolide B was accumulated in cell aggregates in the size smaller than 1mm; however, the cell aggregates in the size bigger than 3mm could only produced bilobalide and ginkgolide A. In the same size aggregates of the suspension cultures the terpene lactone accumulation is strongly effected by the source of the explant. When the size of cell aggregates was in less than 1mm, the concentration of bilobalide, ginkgolide A and B in the cell suspension cultures derived from the embryos was 2, 1.4 and 0.56-fold, respectively, higher than that of cell cultures derived from seedling stems.

BACKGROUND: Methamphetamine (MA) has neurotoxic effects to central nervous system. However, as the 5-hydroxytryplamine reuptake enhancer, it is uncertain that if there are protective effects of tianeptine to the damages of 5-hydroxytryp-taminergic neurons caused by MA.OBJECTIVE: To investigate the neurotoxicity of MA and the neuroprotective effects of tianeptine as well as the acting mechanism.DESIGN: Randomized case control study based on animals.SETTING: Animal research room and pathology research room of a university.MATERIALS: The experiment was completed in the Experimental Animal Centre of Sichuan University and Molecular Pathology Laboratory of West China Hospital during June to August 2003. Totally 25 male Wistar rats were injected MA through abdominal cavity to build model. Methamphetamine was provided by National Institute for the Control of Pharmaceutical and Biological Products(NICPBP) while tianeptine was given by French Servier Company (Batch No. OE3086). The TUNEL testing kit was purchased from Boehringer Mannheim Company.INTERVENTIONS: There were one control group and four experimental groups(A, B, C, D). A group was used intraperitoneal injection of MA while B, C, D, groups were administered tianeptine 7 days, 4 days before and the same day of MA administration. Normal saline with same volume was injected into rats of control group. HE stain and silver stain were conducted after experiment to observe the morphologic changes of neurons. And TUNEL method was used to detect apoptotic cells.MAIN OUTCOME MEASURES: The HE stain and silver stain of brain tissue sections and counts of TUNEL positive neurons.RESULTS: MA could damage the axon and dendrite of neurons and the absorbance of silver positive cell was(50.74 ± 1.86) . It could also induce cell apoptosis while the apoptotic cell count every high power field was 29.26 ±4. 14. There were less apoptotic cells in the group with 7 days usage of tianeptine with the cell count of( 18.90 ± 1.60) per high power field.CONCLUSION: MA can cause neurotoxicity by inducing cell apoptosis.And giving tianeptine in advance can protect neurons.
