OBJECTIVETo explore the therapeutic effect of auricular therapy combined with optimized Yinxieling Formula on psoriasis vulgaris.

METHODSA randomized controlled single-blind clinical trial on 84 outpatients with psoriasis vulgaris was conducted. The patients were randomized to a treatment group (43 cases treated by auricular therapy combined with optimized Yinxieling Formula) and a control group (41 cases treated by optimized Yinxieling Formula alone) according to a random number generated by SPSS 17.0 software. The treatment duration for both groups was 8 weeks. The therapeutic effect was comprehensively measured by the primary outcome measure [Psoriasis Area and Severity Index (PASI) reduction rate] and the secondary outcome measure [PASI, Visual Analogue Scale (VAS), Dermatology Life Quality Index (DLQI), Self-rating Depression Scale (SDS), and Self-rating Anxiety Scale (SAS)]. The outcomes of both groups were obtained and compared before and after the intervention.

RESULTSThe PASI reduction rate in the treatment group was 74.4% (32/43), which was higher than that in the control group (36.6%, 15/41, P<0.01). The PASI scores decreased in both groups after treatment and was lower in the treatment group compared with the control group P<0.01). With stratified analysis, there were significant differences between the PASI scores in the following subgroups: age 18-30, baseline PASI>10 and stable stage (P<0.05). DLQI decreased in both groups on some categories after treatment, but there were no significant differences between the two groups in SDS, SAS and VAS (P >0.05). No obvious adverse reactions were found in either group.

CONCLUSIONThe therapeutic effect of auricular therapy combined with Optimized Yinxieling Formula was superior to Optimized Yinxieling Formula alone with no obvious adverse reaction.

Objective: To explore whether the pro-inflammatory effect of endoplasmic reticulum stress in placental tissues involves in the genesis of gestational diabetes mellitus (GDM). Methods: Forty gravidas who underwent regular prenatal examinations and delivered at Tongji Hospital were recruited from January to December, 2016. Among them, 20 were GDM women (GDM group), and the remaining twenty were served as the control, which were selected from those without GDM and matched for age and gestational weeks to the GDM group. Placental tissues were collected from the two groups. The ultrastructure of endoplasmic reticulum in trophoblast cells was observed under transmission electron microscope. The expression of glucose-regulated protein-78 (GRP-78), a marker protein for endoplasmic reticulum stress, and C/EBP homologous protein (CHOP) were detected using Western blotting. Five placental tissue samples were collected from normal gravidas for explant culture. Three subgroups were set up according to different culturing methods including culturing with IL-1β (5 ng/ml) for 20 h (IL-1β model group), 30 μmol/L thapsigargin (TG, an endoplasmic reticulum stress agonist) for 2 h after treating with IL-1β (5 ng/ml) for 18 h (IL-1β+TG intervention group) or with no stimulation (blank control group). Western blotting was used to detect the expressions of GRP-78, CHOP and glucose transporter 4 (GLUT4) in placenta explants. The mRNA expressions of interleukin-6 (IL-6) and tumor necrosis factor-α (TNF-α) were determined by real-time fluorescence quantitative polymerase chain reaction (RT-PCR). Statistical analysis was performed using one-way analysis of variance, LSD and t test. Results: (1) In the GDM group, increased number and size of endoplasmic reticulum cisternae were observed in trophoblast cells. Moreover, obviously dilated endoplasmic reticulum and different size of fragments and vesicles were also seen under electron microscope. While the endoplasmic reticulum in the placental tissues of the control group showed no obvious swelling. (2) The expression of GRP-78 and CHOP protein in the GDM group were higher than those in the control group (0.90±0.17 vs 0.48±0.08, t=2.24; 0.85±0.13 vs 0.46±0.12, t=2.10; both P<0.05). (3) Compared with the blank control group, the expression of GRP-78 and CHOP protein in the IL-1β model group increased significantly (0.87±0.18 vs 0.36±0.07, t=2.67; 1.14±0.09 vs 0.78±0.06, t=3.20; both P<0.05); but the expression of GLUT4 protein significantly decreased (1.00±0.14 vs 2.21±0.49, t=2.40, P<0.05); the expressions of IL-6 and TNF-α mRNA significantly increased (0.89±0.23 vs 0.30±0.06, t=2.31; 0.62±0.16 vs 0.17±0.09, t=2.29; both P<0.05). Compared with the IL-1β model group, the expression of GRP-78 and CHOP protein significantly increased in IL-1β+TG group (2.02±0.32 vs 0.87±0.18, t=3.11; 2.18±0.31 vs 1.14±0.09, t=3.16; both P<0.05); the expression of GLUT4 protein significantly decreased (0.39±0.19 vs 1.00±0.14, t=2.66, P<0.05); the expression of IL-6 and TNF-α mRNA increased significantly (1.67±0.25 vs 0.89±0.23, t=2.26; 1.42±0.27 vs 0.62±0.16, t=2.51; both P<0.05). Conclusions Endoplasmic reticulum stress may be associated with increased release of pro-inflammatory cytokines in placental tissues of some GDM women and involved in the onset and development of GDM.

OBJECTIVETo clone the recombinant human islet neogenesis-associated protein (rhINGAP) gene for its secretory expression in Pichia pastoris.

METHODSINGAP gene was amplified with PCR and inserted between Xho I and EcoR I downstream sites of the alpha factor of the recombinant plasmid alpha/pUC18. The fusion gene of alpha factor and INGAP was subsequently inserted between BamH I and EcoR I sites of the plasmid pPIC9K of P. pastoris. After confirmation with restriction enzyme digestion and sequencing, the positive recombinant plasmid that integrated INGAP gene was linearized with Sal I digestion and transformed into the yeast host strain GS115 through electroporation. The yeast transformants that harbored the INGAP gene with high copies were selected with the auxotroph medium and G418, followed then by PCR verification of the positive transformants, from which the expression of recombinant human INGAP was induced with methanol as the only carbone source. The antigenic activity of the desired protein was then detected using Western blotting and enzyme-linked immunosorbent assay (ELISA).

RESULTS AND CONCLUSIONThe recombinant expression plasmid INGAP/pPIC9K was successfully constructed, and 3 positive transformants were obtained. The expressed protein showed good antigenic activity as confirmed by Western blotting and ELISA.
