Objective: To develop a sensitive and rapid liquid chromatography-electrospray ionization-tandem mass spectrometry (LC-ESI-MS/MS) method for the simultaneous determination of wogonin, coptisine, berberine, palmatine, jatrorrhizine, phellodendrine, magnoflorine, and wogonoside in rat plasma and to evaluate the pharmacokinetic characteristics of Huanglian Jiedu Decoction (HJD). Methods: LC separation was performed on an Acquity HSS T3 column (100 mm × 2.1 mm, 1.8 μm) using gradient elution with the mobile phase consisting of acetonitrile and 0.1% formic acid water. The detection was accomplished by using positive electrospray ionization in multiple-reaction monitoring mode. Plasma samples were pretreated by protein precipitation. Results: The method showed a good linearity over a wide concentration range (r2 > 0.99). The lower limits of quantification were 0.20 ng/mL for coptisine and phellodendrine, 0.48 ng/mL for berberine, 0.10 ng/mL for jatrorrhizine, 0.32 ng/mL for magnoflorine, 0.30 ng/mL for palmatine, and 4.80 ng/mL for wogonin and wogonoside, respectively. The intra- and inter-day precision of the analytes was less than 12.11%, while the accuracy was between -14.46% and 4.86%. The mean recovery of all the analytes ranged from 93.10% to 110.91%. Conclusion: This validated method offers the advantages of high sensitivity. It is successfully applied to evaluating the pharmacokinetic properties of HJD. © 2014 Tianjin Press of Chinese Herbal Medicines.

The nuclear transcription factor nuclear factor erythroid 2-related factor 2 (NRF2) plays a crucial role in maintaining cellular redox homeostasis. The aberrant NRF2 signaling confers enhanced antioxidant capacity, which is linked to tumor progression and therapeutic resistance. The current study investigates the biological effects and molecular mechanism of tribbles homolog 3 (TRIB3), a stress-induced protein, in regulating cell survival and apoptosis in lung cancer. This study first performed the RNA sequencing data analysis with 576 lung adenocarcinoma patients from the cancer genome atlas (TCGA) database. The NRF2- antioxidant response element (ARE) signature was enriched in patients with high TRIB3 expression. Dual-luciferase reporter assay and real-time quantitative polymerase chain reaction (PCR) were used to confirm the effect of TRIB3 on the kelch-like ECH-associated protein-1 (KEAP1)-NRF2 pathway. Abrogation of TRIB3 impaired NRF2 transcriptional activity and reduced the expression of its target genes. Moreover, TRIB3 enhanced NRF2 stability via blocking KEAP1-NRF2 interaction. TRIB3-depletion promoted reactive oxygen species (ROS) production, restrained cell proliferation, and enhanced carboplatin-induced apoptosis. In addition, NRF2 overexpression recovered the tumor inhibition effect of TRIB3-depletion. Consistently, TRIB3 failed to modulate apoptosis in NRF2 depletion cells. In summary, this study shows that TRIB3 inhibits the KEAP1-NRF2 interaction and upregulates the transcriptional activity of NRF2, thereby promoting lung cancer cell proliferation and reducing the sensitivity to chemotherapy. Targeting the TRIB3-NRF2 signal axis may become a new strategy for ROS homeostasis and lung cancer treatment.

Objective To evaluate the effect of isoflurane or sevoflurane inhalation before and after gestation on the offspring brain development. Methods Thirty female adult Sprague Dawley rats were randomly assigned into 5 groups(n=6 each):control group(group C),group that ex?posed to isoflurane with the concentration of 1.6%for 6 hours before gestation(group BI),group that exposed to isoflurane with the concentration of 1.6%at the 6th,10th,14th and 18th day for 6 hours(group PI),group that exposed to sevoflurane with the concentration of 2.4%for 6 hours before gestation(group BS),and group exposed to sevoflurane with the concentration of 2.4%at the 6th,10th,14th and 18th day for 6 hours after gestation (group PS). Twelve offspring rats from pregnant rats in each group were chosen on the day of birth(T1),and 7th,14th and 28th days after birth(T2, T3 and T4)and sacrificed,and the hippocampi were then isolated. Hematoxylin and eosin stain were adopted to observe the tissue pathological change. Electron microscope was used to observe the neuron ultrastructure change of hippocampus. Immolunohistochemistry was used to detect cas?pase?3,the expression of growth associated protein?43(GAP?43)and neuronal nitric oxide synthase(nNOS). Results Compared with group C, no significant change was found in caspase?3,GAP?43 and nNOS expression in offspring rat hippocampus in groups BI and BS(P>0.05),and no damage change in hippocampal was seen by HE staining and electron microscopy. In group PI and PB,the expression of caspase?3 was significantly up?regulated,the expression of GAP?43 and nNOS was down?regulated at T1 to T3(P<0.01),and structural changes in cell were seen by electron microscopy. In group PI,significant pathological changes in hippocampal were seen by HE staining at T1 to T3. Compared with group PI,the expres?sion of GAP?43 and nNOS was significantly up?regulated(P<0.01),and the expression of caspase?3 was down?regulated at T1 to T3(P<0.01). Conclusion Isoflurane or sevoflurane inhalation before gestation does not affect the offspring brain development,while isoflurane or sevoflurane in?halation after gestation can induce transient abnormal change of offspring brain development,and isoflurane′s toxicity was greater than sevoflurane.

One hundred and ten postmenopausal women,complaining vaginal discomfort,recurrent urinary tract infections or painful intercourse and visiting the hospital between March 2014 and February 2015 were enrolled in the study.Among them,58 patients received vaginal administration of estriol estriol ointment (group A) and 52 patients received conventional treatment (group B).There were no significant differences in mean age of menopause and mean menopause duration between two groups.The clinical symptoms,vaginal health scores,pelvic organ prolapse were observed after treatment.After 6-month treatment,the female vaginal health score was significantly improved in women group A,the rate of urinary orifice was reduced (78％ vs.7％),and the rate of pelvic organ prolapse was decreased (36％ vs.21％).The geritourinary syndrome of menopause is a new term for vulvovaginal atrophy with clinical characteristics of multi-system changes in postmenopausal women,including atrophic vaginitis,female urogenital diseases,and pelvic organ prolapse.The new diagnostic criteria are needed for evaluation and management of geritourinary syndrome.
