Chinese Journal of Medical Genetics 2019;36(2):168-170
OBJECTIVE:
To identify a rare large off ladder (OL) allele at the Penta E locus.
METHODS:
Chelex-100 was used to extract DNAs from the blood samples. The PCR fragments were purified, extracted, and subjected to TA cloning and sequencing.
RESULTS:
An OL allele was identified by the PowerPlex™ 21 at the Penta E locus, which was postulated as allele 26 based on assigned size. The OL allele was verified as a novel fragment containing 26 full AAAGA repeats.
CONCLUSION
OL alleles and microvariants should be verified by direct sequencing. Typing of OL alleles has significance for both daily work and forensic genetics.

In a continuing study of the fermented noni (Morinda citrifolia) juice exudates, five compounds, heptanyl 2-O-β-D-xylofuranosyl-(1 → 6)-β-D-glucopyranoside (1), n-butyl β-D-glucopyranoside (2), (1S)-(3-ethenyl-phenyl)-1,2-ethanediol (3), (2S)-2-hydroxybutanedioic acid (4), and daucosterol (5) were isolated from the buthanol partition of the extract. The structures of the isolates were identified by 1D and 2D NMR, and MS experiments, as well as by comparison of their data with the published values. Among the isolates, compounds 1 – 3 were isolated for the first time from the plant species. The isolated compounds were evaluated for their cancer chemopreventive potential based on their ability to inhibit nitric oxide (NO) production and tumor necrosis factor alpha (TNF-α)-induced NF-κB activity, and quinonone reductase-1 (QR1)-inducing effect.

The study is to develop a method to determine 3 batches leaves of Nauclea officinalis and stems of N. officinalis by HPLC. The differences between strictosamide contents and fingerprints was compared, then chromatographic peak of fingerprints was validated with the assistance of LC-MS. The strictosamide contents in stems of N. officinalis were higher than leaves of N. officinalis. The main chemical composition in leaves of N. officinalis and stems of N. officinalis were alkaloid which revealed by LC-MS. There are 7 chemical compositions were same between them, but the chemical composition in leaves of N. officinalis is more than stems of N. officinalis. This provides a scientific basis for the development of the potential medicinal value of leaves of N. officinalis and the sustainable utilization of N. officinalis.

A rapid and validated UPLC-MS method was developed for investigating the absorbed components of Paederia scandens (Lour.) Merrill (P. scandensy) in rat plasma. The bioactive constituents in plasma samples from rats administrated orally with P. scandens extract were analyzed by Ultra-performance liquid chromatography quadrupole time-of-flight mass spectrometry (UPLC-Q-TOF-MS). Four prototype compounds were identified in rat serum as potential bioactive components of P. scandens by comparing their retention times and mass spectrometry data or by mass spectrometry analysis and retrieving the reference literatures. Glucuronidation after deglycosylation was the major metabolic pathway for the iridoid glycosides in P. scandens. These results showed that the methods had high sensitivity and resolution and were suitable for identifying the bioactive constituents in plasma after oral administration of P. scandens. providing helpful chemical information for further pharmacological and mechanistic researched on the P. scandens.

Hemiplegia cruciata (HC) manifests as paralysis of the ipsilateral arm and contralateral leg. Herein, we report a 64-year-old man with weakness of the right leg and of the left arm after multiple sclerosis (MS). His brain and spine magnetic resonance imaging show a lower medulla lesion, which is extended to posterior part of C1 spine through cervicomedullary junction. HC usually results from stroke or trauma, but it is rare as presenting symptom of MS.

OBJECTIVETo define the effect of Curculiginis Rhizoma and its active ingredient orcinol glucoside on PXR-CYP3A of L02 cells in normal and deficiency-cold states, in order to lay a foundation for studies on the mechanism of efficacy expression differentiation of Curculiginis Rhizoma in different states.
METHODSerums of normal and deficiency-cold rats were adopted to culture L02 cells and induce cells in normal and deficiency-cold states. After aqueous extracts from Curculiginis Rhizoma and its active ingredient orcinol glucoside were used in cells in different states, PXR protain expression and CYP3A activity of L02 cells in normal and deficiency-cold states were observed.
RESULTMTT results showed that aqueous extracts from Curculiginis Rhizoma and orcinol glucoside could significantly enhance viability of L02 cells. Aqueous extracts from Curculiginis Rhizoma could significantly reduce PXR protein expression of L02 cells in normal state, while orcinol glucoside could significantly reduce CYP3A activity and PXR protein expression of L02 cells in normal state. Meanwhile, aqueous extracts from Curculiginis Rhizoma could significantly increase CYP3A activity and PXR protein expression of L02 cells in deficiency-cold state, while orcinol glucoside could significantly reduce CYP3A activity and increase PXR protein expression of L02 cells in deficiency-cold state.
CONCLUSIONCurculiginis Rhizoma can activate PXR and induce CYP3A activity of L02 cells in deficiency-cold state, but with no effect or even counteraction on PXR and its induced CYP3A of L02 cells in normal state.
