Objective To investigate the effects of 13-hexyl-berbefine hydroehlofide (HB-13) and 13-hexyl-paimatine hydrochloride (HP-13) on the activation of nuclear factor-kappa B (NF-kB) and phosphorylation of p38 mitogen-activated protein kinase (MAPK) in a human keratinocyte cell line, HaCaT stimulated by tumor necrosis factor alpha (TNF-α). Methods HaCaT cells were cultured in the presence of various concentrations (0.39, 0.78, 1.56 μg/mL) of HB-13 or HP-13 for 120 minutes followed by the stimulation with recombinant human TNF-α for 120 minutes (in phosphorylatEd-IkB-α test) or 15 minutes (in phosphorylated-p38 test). Then, HaCaT cells were disrupted, total protein was extracted, and the expressions of phosphorylated I B-α and phosphorylated p38 were detected with Western blot. HaCaT cells receiving neither pretreatment nor stimulation served as blank control, untreated HaCaT cells stimulated by rhTNF-α as stimulator control, and HaCaT cells pretreated with turmeric root tuber and stimulated by rhTNF-α as positive control. Results From 0.39 to 1.56 μg/mL, both HB-13 and HP-13 significantly inhibited the expression of p-IkB-α in HaCaT cells stimulated by rhTNF-α, and a nonsignificant dose-dependent trend was observed for their inhibitory effect, with the ICo value being 0.441 μg/mL for I-IB-13 (r = -0.990, n = 3, P > 0.05) and 0.832 μg/mL for HP-13 (r = -0.992, n = 3, P > 0.05). In contrast, neither 1-113-13 nor HP-13 within the experiment concentration range had a significant effect on the expression of p-p38 in HaCaT cells stimulated by rhTNF-α (P > 0.05). Conclusions Within the experimental concentration range, both HB-13 and HP-13 can inhibit the activation of NF-kB in HaCaT cells induced by TNF-α signal, but neither of them suppress the phosphorylation of p38MAPK induced by TNF-α signal in HaCaT cells.

Objective To investigate the effects of triptolide on the expression of a series of proteins associated with interferon-γ (IFN-γ)signaling in HaCaT keratinocytes.Methods After pretreatment with difrerent dosages of triptolide(10-10-10-7 mol/L),HaCaT cells were stimulated by recombinant human IFN-γ(rhIFN-γ,500 U/mL)for various periods followed by the collection of cells.Then,total protein was extracted from these cells and subjected to Western blotting for the detection of expression of interferon-γ receptor α(IFN-γRα),phosphorylated Janus kinase 2(pJAK2)and suppressor of cytokine signaling (SOCS1).Results Triptolide at the concentrations of 10-8 mol/L and 10-7 mol/L significantly inhibited the IFN-γRα expression upregulated by rhIFN-γ(both P＜0.05).The expression of pJAK2 induced bv rhIFN-γ was also suppressed by triptolide at the concentrations of 10-9 moI/L and 10-8 mol/L(both P＜0.05).The inhibition of triptolide on IFN-γRα and pJAK2 expression was dose-dependent and the 50%inhibitory concentrations(IC50 value)were 1.37×10-8 mol/L and 2.83×10-9 mol/L,respectively.On the contrary,triptolide upregulated the expression of SOCS1 stimulated by rhIFN-γ at the concentrations of 10-10,10-9 and 10-8 mol/L(P＜0.05,0.05,0.01,respectively)with the 50%effective dosage(ED50 value)at 3.32 × 10-11 mol/L.Conclusions By inhibiting the expression of IFN-γRα as well as phosphorylation of JAK2 and upregulating the expression of SOCS1,triptolide inhibits the phosphorylation of STAT-1,resulting in the inhibition of genetic transcription of multiple inflammatory factors induced by IFN-γ signaling in HaCaT keratinocytes,and the inhibition probably contributes to the efficacy of triptolide in the treatment of IFN-γ-dependent inflammatory skin disorders,such as psoriasis.

METHODS: The model of hypoxic and hypercapnic 1, 2, 4-week group (HH 1 week, HH 2 weeks, HH 4 weeks) and control group was set up. NO content in plasma, CAT and SOD in rat lung were determined by spectrophotometry. The sGC activity in lung tissue was detected by enzyme kinetic analysis. cGMP content in lung tissue was examined with ~ 125 I-radioimmunoassay. RESULTS: The mean pulmonary artery pressure (mPAP) showed significantly higher in HH 1 week, HH 2 weeks and HH 4 weeks groups compared with control group (all P

Objective To investigate the expression of IFN-γ, IL-5, IL-17 and TGF-βby Th cells and Th17 cells in rats with allergic rhinitis upon the intervention of IL-10.Methods SD rats were ran-domly divided into three groups including allergic rhinitis ( AR ) group, IL-10 treated group and control group (n=10).Rats in AR group and IL-10 treated group were sensitized by injection of ovalbumin (OVA) and aluminum hydroxide on the 1st, the 7th and the 14th days.The rats treated with equal volume of saline were set up as the control.The corresponding interventions ( OVA, OVA and IL-10, saline) were respec-tively given to rats in each group on the 21th day for 7 consecutive days.The clinical manifestations in rats were observed within 30 minutes after each administration.Serum samples were collected at 48 hours after the last challenge for the detection of IgE and OVA-sIgE.ELISA and Western blot assay were performed to detect IFN-γ, IL-5, IL-17 and TGF-βin nasal mucosa samples.Results Some characteristic symptoms of AR were observed in rats from AR group and IL-10 treated group.Compared with IL-10 treated rats, rats in AR group showed severe clinical symptoms such as constant rubbing and tearing of the eyes (P<0.05).The levels of IgE and OVA-sIgE in serum samples and the levels of IFN-γ, IL-5, IL-17 and TGF-βin nasal tis-sues were significantly increased in rats with RA (P<0.05), but were reduced with IL-10 intervention (P<0.05).Conclusion Exogenous IL-10 could be used to treat AR by reducing the expression of IFN-γ, IL-5, IL-17 and TGF-βin nasal tissues.

METHODS: Twenty-four rats were randomly divided into three groups: control group(A),hypoxic hypercapnic group(B), hypoxic hypercapnia+ diltiazem group (C), constitutive endothelial NOS(ceNOS) were observed in arterioles of rats using the technique of immunohistochemistry,ceNOS mRNA were observed by the technique of in situ hybridization . RESULTS: (1)mPAP was significantly higher in rats of B group than that of A and C group( P 0 05),but mCAP was lower in rats of C group than that in B group.(2)Light microscopy showed WA/TA (vessel wall area/total area) was significantly lower in rats of C group than that of B group ( P

Objective To investigate the association between the minisatellite polymorphism in the first exon of PLA2G4C gene and schizophrenia, and to reveal the important role of DNA sequence polymorphism in the pathogenesis of schizophrenia.Methods The minisatellite polymorphisms in the first exon of PLA2G4C gene in 91 patients with schizophrenia (case group)and 81 healthy persons (control group)were detected with PCR-sequencing analysis.The chi-square (χ2 )goodness-of-fit test was used to analyze the distribution of the PLA2G4C minisatellite polymorphism in various groups and to explore the association between the minisatellite polymorphism in the first exon of PLA2G4C gene and schizophrenia. Results There were minisatellite polymorphisms in PLA2G4C gene.Three kinds of polymorphisms 1×27 bp,2×27 bp and 3×27 bp were found by sequencing.The distribution of allelic frequencies at PLA2G4C polymorphism showed no statistical significance between case group and control group (P>0.05 ). No statistically significant difference was found in 3-homozygous haplotypes in PLA2G4C gene between case group and control group (P>0.05).At the same time,there was no statistically significant difference between 3-heterozygous haplotypes in PLA2G4C gene between case group and control group (P>0.05).Conclusion The minisatellite polymorphisms in the first exon of PLA2G4C gene are found,but the minisatellite polymorphism in the first exon of PLA2G4C gene may be not associated with the occurrence of schizophrenia.

OBJECTIVE: To analyze the clinical significance of combined newborn hearing and deafness gene screening in Yuncheng area of Shanxi Province. METHODS: Results of audiological examinations, including transient evoked otoacoustic emission and automatic discriminative auditory brainstem evoked potentials, for 6 723 newborns born in Yuncheng area from January 1, 2021 to December 31, 2021, were retrospectively analyzed. Those who failed one of the tests were considered to have failed the examination. A deafness-related gene testing kit was used to detect 15 hot spot variants of common deafness-associated genes in China including GJB2, SLC26A4, GJB3, and mtDNA12S rRNA. Neonates who had passed the audiological examinations and those who had not were compared using a chi-square test. RESULTS: Among the 6 723 neonates, 363 (5.40%) were found to carry variants. These have included 166 cases (2.47%) with GJB2 gene variants, 136 cases (2.03%) with SLC26A4 gene variants, 26 cases (0.39%) with mitochondrial 12S rRNA gene variants, and 33 cases (0.49%) with GJB3 gene variants. Among the 6 723 neonates, 267 had failed initial hearing screening, among which 244 had accepted a re-examination, for which 14 cases (5.73%) had failed again. This has yielded an approximate prevalence of hearing disorder of 0.21% (14/6 723). Among 230 newborns who had passed the re-examination, 10 (4.34%) were found to have carried a variant. By contrast, 4 out of the 14 neonates (28.57%) who had failed the re-examination had carried a variant, and there was a significant difference between the two groups (P < 0.05). CONCLUSION Genetic screening can provide an effective supplement to newborn hearing screening, and the combined screening can provide a best model for the prevention of hearing loss, which can enable early detection of deafness risks, targeted prevention measures, and genetic counseling to provide accurate prognosis for the newborns.

Objective To investigate the effect of BOPPPSmodel in the clinical teaching of ward inspection in the standardized training of residents in the department of obstetrics and gynecology. Methods Residents who participated in the standardized training in the department of obstetrics and gynecology in our hospital (January to December 2016) were randomly divided into two groups: teaching experimental group(n=30) and control group(n=35). BOPPPSteaching and traditional teaching methods were applied respectively. The comprehensive assessment scores of the theory test, skill operation test and questionnaire survey were evaluated in both groups. Results The comprehensive assessment scores of the fundamental knowledge test, clinical skill operation test and questionnaire survey in the teaching group were significantly higher than those in the control group(P＜0. 05). Most students in BOPPPSteaching group held the opinions that BOPPPSteaching could help to improve learning initiative, cultivate communication skills of doctors to patients, stimulate clinical thinking, and improve learning efficiency. At the same time, students also mentioned that the BOPPPSmodel had a greater pressure on them, which consumed a great number of time and energy. There were significant differences in the scores between the two groups(P＜0. 05). Conclusion Application of BOPPPSmodel teaching of ward inspection in the standardized training of residents in the department of obstetrics and gynecology can contribute to the improvement of teaching quality and comprehensive ability of the trainees.
