目的:探讨代谢综合征与IVF-ET/ICSI过程及结局的关系.方法:回顾性分析从2009年1月至2013年3月于我院行长方案IVF或ICSI-ET辅助助孕患者共145个周期,所有患者在进入助孕周期前均未对代谢综合征进行预处理,按照WHO制定的亚洲成人BMI标准[1]的不同分为三组:A组(正常组,18.5 kg/m2≤BMI <23 kg/m2)、B组(超重组,23 kg/m2≤BMI< 25 kg/m2)、C组(肥胖组,BMI≥25 kg/m2);又根据2005年国际糖尿病联盟(IDF,2005年)[3]制定的代谢综合征标准降B、C各分为两组:B1组(超重非代谢综合征组),B2组(超重代谢综合征组),C1组(肥胖非代谢综合征组),C2组(肥胖代谢综合征组);比较各组患者一般情况、治疗情况及妊娠结局.结果:(1)基础情况:BMI值及腹围A、B、C三组差异显著(P<0.01).(2)治疗情况:Gn用量C2组均稍高于其他各组(P<0.05);HCG日E2值及MII期卵细胞数:B2、C2组均显著低于A组(P<0.01);获卵数,胚胎数B2、C1、C2组均低于A组(P<0.05);优质胚胎数C2组显著少于A组(P<0.01).(3)妊娠结局:胚胎种植率、临床妊娠率A、B1、C1组均显著高于B2及C2组(P<0.01);不良妊娠率B2、C2组显著高于A组(P<0.01),B2、C2组的不良妊娠率高于B1、C1组,但无统计学意义(P>0.05).结论:代谢综合征可能通过降低卵巢反应及内膜容受性来对患者产生不良影响.接受ART治疗的代谢综合征超重及肥胖患者妊娠结局明显差于正常体重患者,但超重及肥胖未伴代谢综合征的患者和正常体重患者的妊娠结局并不明显.  相似文献

The expression of intercellular adhesion molecule-1 (ICAM-1) in mouse B16 and human melanoma cell lines was investigated by indirect immunofluorescence using a FACScan analyzer. Mouse B16 melanoma cell lines (B16-F1 and F10) did not express ICAM-1 under ordinary culture conditions. Neither in vitro hyperthermia at 41°C for 3 or 6 hr nor cytokines such as γ interferon (IFN-γ) or tumor necrosis factor α (TNF-α) induced ICAM-1 expression in B16 melanoma cell lines. A combination of IFN-γ with TNF-α caused slight induction of ICAM-1 expression in the B16-F10 melanoma cell line. Hyperthermia at 41°C for 3 hr in combination with the cytokines induced a slight expression of ICAM-1 in the B16-F1 melanoma cell line. Hyperthermia at 41°C for 3 hr or 6 hr did not induce de novo ICAM-1 expression but hyperthermia at 43°C for 6 hr caused rather suppression of the expression of ICAM-1 in the three human melanoma cell lines tested. In contrast, they showed a clear increase in the expression of ICAM-1 after treatment with either with IFN-γ or TNF-α, and the expression was further augmented by a combination of the two cytokines. Treatment with cytokines in combination with hyperthermia at 41°C or 43°C for 3 hr did not augment the expression of ICAM-1 over that in cytokine-treated human melanoma cell lines, at normal temperatures. Thus, it is concluded that mouse B16-F1 and F10 melanoma cell lines are different from human melanoma cell lines in terms of induction of ICAM-1 expression by cytokines and/or hyperthermia.  相似文献

Acquired C1 esterase inhibitor deficiency is a clinical syndrome closely resembling hereditary angioedema in which most patients have an associated malignancy of B cell lineage. Sera from 33 patients with B cell neoplasms were assayed for C1 esterase inhibitor level by rocket immunoelectrophoresis. The clinical summary of a patient who met the biochemical criteria for acquired C1 esterase inhibitor deficiency (low C1 esterase inhibitor, low C4) is presented. We hypothesize that this syndrome represents an autoimmune reaction involving tumor cell rejections and of potential benefit to the patient.  相似文献

Abstract Wide variations in susceptibility to skin tumor development by chronic ultraviolet light (UV) exposure and antigenicity of induced tumors which is estimated by tumor rejection in syngeneic recipients have been recognized among various murine strains. To examine the effect of parent genetic background on latency and antigenicity of UV-induced tumors originating in F1 hybrids, we induced skin tumors in three mouse strains: BALB/c, C57BL/6, (B6), and C3H/HeMs (C3H/He), and their F1, hybrids: (BALB/c×C3H/He)F1, (CC3F1), (BALB/c×B6)F1, (CB6F1) and (C3H/He×B6)F1, (C3B6F1) by exposing mice to UV radiation (0.44 mW/ cm2 for 1 h) three times a week, and analyzed whether the UV-induccd tumors originating in F1 hybrids possess the similar property in latency or antigenicity as seen in the UV-induced tumors derived from the parent strains. The latency of tumor induction by chronic UV exposure in C3H/He, BALB/c and their F1, hybrid CC3F1, was relatively short whereas that of B6 was relatively long, and that of F1, hybrids with B6 (CB6F, and C3B6F1) was intermediate. On the other hand, the low antigenicity as progressive growth behavior of UV-induced tumors in syngeneic recipients was observed not only in tumors derived from C3H/He but also in those from F, hybrids with C3H/He (C3B6F1, and CC3F1) whereas most tumors derived from B6, BALB/c and their F1 hybrid CC3F1 were highly antigenic as to be rejected in syngeneic recipients. These findings suggest that the parent genetic quality regulating the susceptibility to tumor induction by chronic UV exposure is co-dominantly inherited into F1 hybrids. On the other hand, that providing the progressive growth behavior of induced tumors appears to be a dominant effect.  相似文献

The therapeutic efficacy of a preparation containing 2.5% bifonazole was investigated by comparing three different treatment modalities—A, B, and C. Group A used bifonazole only on Day 1, Group B applied the cream on Days 1, 2 and 3, and the Group C on Days 1, 3 and 5. Of the patients in Group A 56% had a negative mycological examination at the end of the study. The results obtained in Groups B and C were not significantly different: 92% of the patients had a negative mycological examination at the end of the study. Electron microscope (EM) studies showed morphological alterations such as loss of cytoplasmic organization with shrinkage and folding of the cell membranes after 1 week of treatment only in Groups B and C. We conclude that 2.5% bifonazole is a highly effective treatment for Pityrosporum ovale infection when applied using a 3-day schedule.  相似文献

A single exposure of recipient (C57BL6 X C3H-) F1 (B6C3F1) mice to UVB radiation suppressed the graft-versus-host (GVH) reaction to injected C3H- lymphoid cells, as measured by the popliteal lymph node weight gain assay. Several observations provided evidence to suggest that this effect of UVB radiation is nonspecific and involves an alteration of the host lymphoid cell component of the reaction. First, the nonspecific trauma of mild thermal injury also suppressed the GVH reaction. Second, although treatment of mice with rose bengal and visible radiation suppresses contact hypersensitivity while treatment with eosin and visible radiation does not, both types of phototoxic treatment suppressed the GVH reaction. Third, implantation of spleens from normal B6C3F1 mice into UVB-treated or thermally injured recipient mice at the time of injection of graft cells overcame the suppression of the GVH reaction. Finally, treatment of donor B6C3F1 mice with UVB radiation did not suppress the host-versus-graft reaction in recipient C3H- mice, which suggests that radiation does not alter the stimulatory function of B6C3F1 cells. These findings are all consistent with a hypothesis that UVB radiation suppresses GVH reactivity by reducing the host component of this immune response through diversion of cells from the site of the reaction. Thus an alteration of cell trafficking appears to be an additional pathway by which UVB radiation can produce immunosuppression.  相似文献

In view of evidence suggesting vitiligo is an autoimmune disease, we investigated whether vitiligo is associated with inherited deficiencies of the fourth (C4) and second (C2) component of complement and with certain human leukocyte antigens (HLA). Analysis of functional activities of C4 and C2 in sera of patients with vitiligo (n = 42) showed that 17% of them had a heterozygous C4 deficiency and 5% had a heterozygous C2 deficiency. In the normal control group (n = 30), 3% had a heterozygous C4 deficiency and none had a C2 deficiency. C4 typing by Western blot analysis showed the frequency of the C4A*Q0 allele in the vitiligo patient group to be close to normal. However, the frequency of one C4B*Q0 allele was three times higher, and that of two C4B*Q0 alleles five times higher in the vitiligo patient group than the reported frequencies in normal control groups. Southern blot analysis of Taq1 digests of DNA using C4 and 21-hydroxylase probes showed that two patients with two C4B*Q0 alleles had a deletion of a 21-OHA-C4B segment. In the other patients, having one or two C4B*Q0 alleles, these null alleles probably occurred due to a loss of C4 gene expression. HLA analysis did not show any allelic association of C4A*Q0 or C4B*Q0 with any HLA antigen in vitiligo, but confirmed the previous findings of a negative association with HLA-DR3 and a positive association with HLA-DR4. These results suggest that abnormalities of the C4B gene and the above-mentioned associations with HLA antigens may be some of the risk factors in vitiligo.  相似文献

Background The efficacy of conventional isotretinoin treatment (0·5–1·0 mg kg?1 daily for 16–32 weeks, reaching a cumulative dose of 120 mg kg?1) for acne has been well established. To date, there are many reports regarding the efficacy of low‐dose and intermittent isotretinoin treatment in patients with acne. Data comparing these three therapeutic regimens simultaneously, however, are unavailable. Objectives To evaluate the clinical efficacy and tolerability of low‐dose and intermittent isotretinoin regimens and to compare them directly with conventional isotretinoin treatment. Methods In this study, 60 patients with moderate acne were enrolled and randomized to receive either isotretinoin at 0·5–0·7 mg kg?1 daily (group A), isotretinoin at 0·25–0·4 mg kg?1 daily (group B) or isotretinoin at 0·5–0·7 mg kg?1 daily for 1 week out of every 4 weeks (group C). The total period of drug administration was 6 weeks in group C, and 24 weeks in groups A and B. Evaluations included global acne grading system (GAGS) scores, lesion counts (inflammatory and noninflammatory), patient satisfaction and side‐effects. A 1‐year follow‐up evaluation after the end of treatment was also performed. Results Differences in GAGS scores were statistically significant between groups A and C (P < 0·001) and groups B and C (P = 0·044). There was no significant difference between groups A and B. For the number of inflammatory lesions, there were statistically significant differences between groups B and C (P = 0·048) and groups C and A (P = 0·005). There was no significant difference between groups A and B. For the number of noninflammatory lesions, there were statistically significant differences between groups B and C (P = 0·046) and groups C and A (P = 0·006). There was no significant difference between groups A and B. These results suggest that the conventional and low‐dose regimens have similar efficacy. Intermittent treatment had less effect than either conventional or low‐dose treatments. Patient satisfaction was highest in group B (3·76), followed by group C (3·31), then A (3·06), with statistically significant differences between groups A and B (P = 0·003) and groups B and C (P = 0·019) but no significant difference between groups A and C. This result suggests that the low‐dose regimen is superior to other regimens (conventional or intermittent) in terms of patient satisfaction. Side‐effects were more frequent with conventional treatment compared with low‐dose and intermittent treatments. One year after the end of treatment, two of 16 patients relapsed in group A, three of 17 patients relapsed in group B, and nine of 16 patients relapsed in group C. Conclusions Our study suggests that, when considering tolerability, efficacy and patient satisfaction, low‐dose treatment is most suitable for patients with moderate acne.  相似文献

Abstract We have recently established a mouse model for scleroderma by repeated local bleomycin treatment. In this study, we compared the susceptibility to bleomycin in the development of dermal sclerosis among Balb/c, C3H/He, C57BL/6J, A/J, DBA/2, B10.BR, B10.A, and B10.D2 mouse strains. After either bleomycin or PBS treatment, skin from the injection site was histologically examined. Dermal sclerosis was induced by bleomycin treatment for 4 weeks in all of the strains examined. In particular, C3H/He, DBA/2, B10.D2 and B10.A mice developed intense dermal sclerosis characterized by deposition of homogeneous material in the dermis and thickened collagen bundles. Dermal thickness showed a more than twofold increase following bleomycin treatment, as compared with PBS treatment, except in C57BL/6J and DBA/2 mice. In A/J, C3H/He, B10.A, and B10.D2 mice, dermal thickness showed a more than 2.5-fold increase. Mast cell numbers in sclerotic skin were significantly greater than in PBS-treated skin in Balb/c and B10.A mice after 4 weeks of treatment. We also examined whether bleomycin treatment for 3 weeks could induce dermal sclerosis in C3H mice. Histological examination revealed that epidermal thickness as well as dermal sclerosis was increased in C3H mice following bleomycin treatment for 3 weeks. Increased hydroxyproline content as well as mRNA expression of α1(I) collagen, as determined by Northern blot analysis, were observed following bleomycin treatment. Taken together, we conclude that C3H/He and B10.A mouse strains are bleomycin-’susceptible’, and these strains are considered to be a suitable experimental model of bleomycin-induced scleroderma.

The immunofluorescent patterns of uninvolved and involved skin biopsies from eight patients with atopic dermatitis were studied, using direct immunofluorescence techniques to identify deposits of the immunoglobulins G, A and M as well as the complement factors C1q, C3, C4, C5, factor B and properdin. Immunoglobulin deposits (mainly IgG) were found in five patients, complement deposits in three patients in the basement membrane zone. In three patients the immunofluorescence was positive for C3, in two patients for C1q, C4 and C5. Regarding the factors of the alternative pathway of the complement system, two patients showed deposits of properdin, one of factor B. The changes were not confined to the eczematous lesions, but were found in uninvolved skin too. The most prominent changes were observed in patients with severe disease.  相似文献

Background:  Interleukin (IL)-1α and its receptor antagonist IL-1ra play a role in skin inflammation. Several polymorphisms in the IL1 gene cluster, coding for IL-1α, IL-1ra, and IL-1β, influence their protein expression. Within this cluster, strong linkage disequilibrium has been shown.
Objective:  We studied the association between the polymorphisms IL1A -889 (C→T) and IL1B -31 (T→C) and the concentration of IL-1α and IL-1ra in the stratum corneum (SC).
Method:  In 124 patients with chronic irritant contact dermatitis, we genotyped the IL1A -889 and IL1B -31 polymorphisms and determined the amount of IL-1α and IL-1ra on tape strips obtained from uninvolved skin of the volar forearm.
Results:  The SC IL-1α concentration was 23% and 47% lower in subjects with IL1A -889 C/T genotype and T/T genotype, respectively, compared with wild-type genotype. In subjects with IL1B -31 C/C genotype, the IL-1α concentration was 51% lower compared with C/T and T/T genotypes. The ratio IL-1ra/IL-1α increased twofold in IL1A -889 C/T genotype and threefold in T/T genotype compared with wild type.
Conclusions:  We have shown a clear effect of IL1 genotype on protein expression in the SC. This altered expression may be responsible for the interindividual differences in the inflammatory response of the skin.  相似文献

Summary Genetic polymorphisms of HLA antigens and HLA-linked serum complement components (C2, C4A, C4B and BF) were investigated in 79 Japanese patients suffering from psoriasis. HLA typing revealed increased frequencies of HLA-A1, A2, B39, Bw46, Cw6, Cw7 and Cw11. Among complement components, positive associations were obtained with C4A4 and C4B2 and a negative association with BFF. The major histocompatibility complex haplotype (supratype), HLA-A2-Cw11-Bw46-C2C-BFS-C4A4-C4B2-DRw8 is purported to be a new high-risk haplotype in Japanese patients with psoriasis. Analysis of patients with this supratype via pulsed field gel electrophoresis showed the existence of specific, extensive DNA deletions near HLA-DR genes, but no disease-specific patterns could be observed by means of this technique. The newly-found high-risk haplotype indicates racial and ethnic differences among psoriatic patients.  相似文献

Background Insect repellents and sunscreens are over‐the‐counter products extensively used by the general public. Concurrent application of these products has become widespread in many regions across North America, because of concerns about West Nile virus and skin cancers. Objectives We investigated whether formulation type, application amount, and sequence would affect the percutaneous absorption profiles of the active repellent and sunscreen ingredients. Methods In vitro percutaneous permeation of the repellent N,N‐diethyl‐m‐toluamide (DEET) and the sunscreen oxybenzone from concurrent application of five commercially available products (A, repellent spray; B, repellent lotion; C, sunscreen lotion; D and E, combined repellent/sunscreen lotions) was measured and compared using Franz‐style diffusion cells with piglet skin at 37 °C. Results Penetration of DEET in A and B increased by 1640% and 282%, respectively, when C was applied concurrently. Penetration of DEET in D and E was 53% and 79% higher than that in B. Permeation of DEET from A + C (2 : 1) and A + C (1 : 2) increased by 530% and 278%, respectively. Permeation of oxybenzone was 189% and 280% higher in A + C and B + C than in C. Permeation of oxybenzone in D and E was also 221% and 296% higher than that in C. Permeation of oxybenzone was 196% greater when A was applied on top of C than when C was applied on top of A, while oxybenzone in A + C (1 : 2) permeated 171% more than that in A + C (2 : 1). Conclusions Concurrent application of commercially available repellent and sunscreen products resulted in significant synergistic percutaneous permeation of the repellent DEET and the sunscreen oxybenzone in vitro. The percutaneous penetration profiles were dependent upon the type of formulation, application sequence and application proportion.  相似文献
