Objective To explore the effect of in utero exposure to inlfammation on innate immune response in preterm infants. Methods Forty-seven premature infants with gestational age<35 weeks were recruited in this study. According to his-tological evidence of placental infection, all neonates were divided into intrauterine inlfammation positive group and negative group. Mononuclear cells and monocytes were isolated from umbilical cord blood, and were cultured in vitro in the presence or absence of LPS (100 ng/ml). The levels of interleukin 1β(IL-1β), interleukin 6 (IL-6), tumor necrosis factor alpha (TNF-α) and interleukin 10 (IL-10) in cord blood plasma and monocyte cultural supernatants were measured by ELISA respectively. The level of IL-1β, TNF-α, IL-6 and IL-10 mRNA were detected by Real-time PCR. Expression of HLA-DR on surface of CD14+monocytes and ratio of CD3+CD4+/CD3+CD8+T was analyzed by lfow cytometry. Results (1) The level of cord plasma IL-6 in intrauterine inlfammation positive group was signiifcantly higher than in negative group. (P=0.02). (2) After stimulation of LPS, levels of IL-1β, IL-6, TNF-α, IL-10 in supernatants were increased signiifcantly, in consistence with their mRNA expression (P<0.05) in both groups. (3) Expression of HLA-DR on surface of monocytes was signiifcantly decreased after stimulation with LPS in intrauterine inlfammation positive group (P=0.012), but was signiifcantly increased in negative group (P=0.0305). Con-clusions In utero exposure to inlfammation does not suppress the response of monocytes to LPS in preterm neonates, but impairs the antigen presenting function in monocytes.

Objective: To observe the clinical efficacy of heat-sensitive moxibustion plus Western medicine in treating patients with diabetic peripheral neuropathy (DPN). Methods: A total of 70 patients with DPN were divided into an observation group and a control group by sealed envelope method combined with the random number table method, with 35 cases in each group. The control group was treated with routine medicine, and the observation group was treated with heat-sensitive moxibustion on the basis of the treatment in the control group. After 2 courses of treatment, the scores of Toronto clinical scoring system (TCSS) and vibration perception threshold (VPT) in both groups were observed, and the clinical efficacy was compared. Results: During treatment, 3 cases dropped out in the control group and 4 cases in the observation group. After treatment, the total effective rate in the observation group was higher than that in the control group (P<0.05). The scores of TCSS and VPT in both groups decreased after treatment, and the intra-group comparison showed statistical significance (both P<0.05). The scores of TCSS and VPT in the observation group were lower than those in the control group, and the differences were statistically significant (both P<0.05). Conclusion: Heat-sensitive moxibustion plus Western medicine can improve the symptoms in patients with DPN, and has a better curative effect than the Western medicine alone.

OBJECTIVETo observe the effectiveness and safety of external applying Compound Tripterygium wilfordii Hook F. (TwHF) in relieving joint pain in rheumatoid arthritis (RA) patients.

METHODSIn this double-blinded, randomized multicenter trial, a total of 174 moderately active RA patients were enrolled and randomly assigned to the treatment group (treated with Compound TwHF, 87 cases) and the placebo control group (87 cases). Compound TwHF or placebo was externally applied in painful joints, 20 g each time, once per day for 8 weeks. Self-reported joint pain relief was taken as a primary effective indicator. Visual analogue scale for pain (VAS), disease activity score of 28 joints (DAS28), VAS for general health (GH) were evaluated before treatment, at week 4 and after treatment. Erythrocyte sedimentation rate (ESR) and hypersensitive C reactive protein (hs-CRP) were tested before and after treatment. Menstrual changes in females were observed during treatment. Skin irritation occurred during the recording process was assessed using skin irritation strength. Intention to treat (ITT) was statistically analyzed.

RESULTSThe joint pain relief rate in the treatment group was 90.8% (79/87 cases), higher than that in the placebo control group (69.0%, 60/87 cases; P = 0.001). VAS pain score, DAS28, VAS for GH score were significantly improved in the two groups at week 4 of treatment and after treatment, as compared with before treatment (P < 0.01). ESR and hs-CRP levels significantly decreased in the treatment group after treatment (P < 0.05, P < 0.01). No difference was found in post-treatment VAS pain score, DAS28, VAS for GH score, ESR, or hs-CRP between the two groups (P > 0.05). Eight adverse events occurred in the treatment group (5 skin allergy, 1 intolerance of medical odor, and 2 mild liver injury), while 3 adverse events occurred in the placebo control group (2 skin allergy, 1 mild liver injury). There was no statistical difference in adverse event between the two groups (P > 0.05). No menstrual change occurred in the treatment group.

CONCLUSIONExternal applying Compound TwHF was an effective and safe way to relieve-joint pain of RA patients, which could be taken as an adjuvant therapy.

Estrogen receptors (ERs) are members of nuclear receptors and related to several diseases such as cancer, inflammation and osteoporosis. ERs have two forms, ERα and ERβ, which have different functions and organism distributions. Compounds selectively targeting ERβ can regulate important physiological functions and avoid the side effects caused by targeting ERα. Therefore, selective ERβ ligands have received considerable research interest in recent years. In this article, different kinds of selective ERβ ligands were summarized and their structure-activity relationships were also analyzed.

Transcriptions are regulated by transcription factors. Natural transcription factors usually consist of at least two functional domains: a DNA-binding domain and an effector domain. According to this, novel artificial transcription factors are designed to up or down regulate transcription and expression of a target gene. The Cys2-His2 zinc finger domain is a DNA-binding module that has been widely used as the DNA-binding domain in artificial transcription factors. Each zinc finger domain, which comprises about 30 amino acids that adopt a compact structure by chelating a zinc ion, typically functions by binding 3 base pairs of DNA sequence. Several zinc fingers linked together would bind proportionally longer DNA sequences. According to the "bipartite complementary" library strategy, a pair of zinc finger phage display libraries were constructed. After construction of the libraries, a 9bp sequence (5'-GCAGAGGCC-3') on the promoter of SV40 was chosen as a target for next step. After parallel selection, PCR amplification, desired fragments recovery, re-ligation, and additional rounds of selection, phage enzyme-linked ELISA experiments were performed to identify specific binding clones displaying the zinc fingers with predetermined sequence-specificity to our target sequence. Then two clones with strong ELISA signals were chosen to be tested for binding both to its full target site (5'-GCAGAGGCC-3') and to sites containing single transition mutations. The binding specificity of one of the two clones (clone 3) was shown to be fairly good. The three-finger DNA-binding domain targeted to SV40 promoter, that is, zinc finger sequences on clone 3, was fused to KOX1 suppression domain KRAB and cloned into pcDNA3.1 (+) (which expression product was artificial transcription factor). The zinc fingers (which expression product was the DNA-binding domain of artificial transcription factor) and KRAB domain only (which expression product was effector domain of artificial transcription factor) were also cloned separately into the same expression vector. All constructs contained an N-terminal nuclear localization signal. Every of the vectors (including pcDNA3.1 (+) without inserting sequences) were cotransfected with pGL3-Control and pRL-TK and the activity of luciferase was used to indicate the function of product from transfected expression vectors. Our artificial transcription factor was proved to repress the expression of reporter gene efficiently,while with only DNA-binding domain or effector domain the repression was not remarkable. By adding different effector domains and changing the DNA-binding domain, artificial transcription factor would have a wide range of potential applications.
