腹腔镜手术对不孕症患者的诊断及治疗价值研究

目的探讨腹腔镜手术对不孕症患者的诊断及治疗价值。方法回顾性分析新疆医科大学第一附属医院2010年9月-2014年5月收治的319例不孕症患者的临床资料,对所有患者行腹腔镜下诊断及相应的手术治疗(包括盆腔粘连分解、输卵管造口术、输卵管灼断术等)。结果 319例患者腹腔镜术中检查与术前子宫输卵管碘油造影结果的符合率为72.1%(230/319),其中有43例术中发现子宫肌瘤,56例术中发现输卵管系膜囊肿,8例患者术中发现子宫内膜异位症,有2例患者诊断为盆腔结核,1例术中发现结肠肌瘤(术前考虑卵巢囊肿),其余为不同程度的盆腔慢性炎症。轻度粘连69例,妊娠21例,宫外孕2例,妊娠率33.33%。中重度粘连250例,其中行灼断术34例,灼断术患者后行体外受精及胚胎移植(IVF-ET),妊娠13例,妊娠率38.23%(13/34)。其余216例,失访3例,妊娠31例,宫外孕3例、妊娠率15.9%。结论腹腔镜对诊断输卵管性不孕及盆腔疾病有重要价值,子宫输卵管造影仅能初级筛查,诊断价值有限。在治疗输卵管粘连梗阻中,腹腔镜的治疗价值有待进一步探讨,临床预后与盆腔炎症的程度有关,应个体化选择手术方案。     

Induction of proliferation of B prolymphocytic leukemia cells by phorbol ester and native or recombinant interferon-gamma

Phorbol ester phorbol myristate acetate (PMA) induces proliferation in nonmalignant human B cells and B cells from a patient with B prolymphocytic leukemia (B-PLL). Mitogen-free T cell-derived conditioned medium acts synergistically with PMA in inducing proliferation of B-PLL cells but does not enhance the PMA-stimulated outgrowth of nonmalignant B cells. Interleukin 2 (IL-2) has no effect on the outgrowth of B-PLL cells, and monoclonal antibodies against the IL-2 receptor do not influence the response to PMA and conditioned medium. Recombinant interferon-gamma (IFN-gamma), in contrast, is a potent enhancer of PMA-induced proliferation of B-PLL cells. With gel filtration techniques and with the use of anti-IFN-gamma antibodies, it is shown that IFN-gamma in the conditioned medium is responsible for the observed increase in B-PLL cell proliferation. Preincubation of B- PLL cells with IFN-gamma induces responsiveness to PMA, whereas IFN- gamma alone had no effect on these cells when pretreated with PMA. The combined data show that, in the presence of PMA, native and recombinant IFN-gamma are growth factors for B cells from a B-PLL patient and that IL-2 is not involved in this process.     

Intramembranous bone regeneration differs among common inbred mouse strains following marrow ablation

Various intact and post‐injury bone phenotypes are heritable traits. In this study, we sought to determine if intramembranous bone regeneration following marrow ablation differed among common inbred mouse strains and to identify how early the differences appear. We found a ～four‐fold difference in the regenerated bone volume 21 days after marrow ablation in females from four inbred mouse strains: FVB/N (15.7 ± 8.1%, mean and standard deviation), C3H/He (15.5 ± 4.2%), C57BL/6 (12.2 ± 5.2%), and BALB/c (4.0 ± 4.4%); with BALB/c different from FVB/N (p = 0.007) and C3H/He (p = 0.002). A second experiment showed that FVB/N compared to BALB/c mice had more regenerated bone 7 and 14 days after ablation (p < 0.001), while at 21 days FVB/N mice had a greater fraction of mineralizing surface (p = 0.008) without a difference in mineral apposition rate. Thus, differences among strains are evident early during intramembranous bone regeneration following marrow ablation and appear to be associated with differences in osteogenic cell recruitment, but not osteoblast activity. The amount of regenerating bone was not correlated with other heritable traits such as the intact bone phenotype or soft tissue wound healing, suggesting that there may be independent genetic pathways for these traits. © 2015 Orthopaedic Research Society.

A New Variant of Hereditary Hemolytic Anemia With Stomatocytosis and Erythrocyte Cation Abnormality

A new variant of congenital hemolyticanemia associated with stomatocytosis,reticulocytosis, decreased osmotic fragility, type I autohemolysis and shortened erythrocyte survival without specific splenic sequestration was discoveredin three siblings of Swiss-German ancestry. Increased intracellular sodium(two to three times normal) and slightlydecreased intracellular potassium weredetected. Total sodium efflux was eight-fold greater than normal but total potassium influx was normal and ouabain-sensitive potassium influx was decreased.The ouabain-sensitive sodium efflux:potassium influx ratio was 26:1 ratherthan the 3:2 ratio noted in normal cells.The consanguineous parents, four othersiblings, and 44 other family membershad mild stomatocytosis, reticulocytosis,and, when studied, decreased osmoticfragility, increased autohemolysis, intermediate abnormalities of cation content,cation flux, and moderate shortening oferythrocyte survival. Autosomal dominant inheritance was suggested. Noabnormalities of RBC enzymes, hemoglobin or lipids were observed. No abnormalities of membrane protein weredetected on acrylamide gel. Substratedepletion of these hypermetabolic cellsresulted in intracellular dehydrationwith potassium loss in excess of sodiumgain and decreased deformability. Although the exact nature of the defectresponsible for hemolysis is unknown,this syndrome differs from other hereditary hemolytic anemias associated withstomatocytosis.

Fear Assessment in Inflammatory Rheumatic diseases (FAIR) questionnaire: a cross-cultural adaptation and validation to the Turkish language

In chronic inflammatory rheumatic diseases (CIRD), it is important to understand patients’ fears towards their disease in order to improve patient-physician dialog, to raise the quality of care offered, and to optimize treatment adherence. In this study, we aimed to translate the Fear Assessment in Inflammatory Rheumatic diseases (FAIR) questionnaire into Turkish and evaluate its psychometric properties in patients with CIRD. One hundred fifteen patients filled the provided socio-demographic information form, FAIR-Tr questionnaire, Hospital Anxiety and Depression Scale (HADS), and Beck’s Hopelessness Scale (BHS). For the analysis of short-term reliability, 50 patients re-filled the FAIR-Tr questionnaire 1 week later. Internal consistency was evaluated with Cronbach’s α coefficient and test-retest reliability was evaluated with intraclass correlation coefficients (ICC). Construct validity analysis was investigated based on the correlation with HADS and BHS. All patients found FAIR-Tr easily understandable and acceptable. FAIR-Tr internal consistency (Cronbach’s α?=?0.93) and test-retest reliability (ICC?=?0.91) were excellent. Psychometric validation was proved upon observing high correlation with HADS (Anxiety, r?=?0.77; Depression, r?=?0.70) and moderate correlation with BHS (r?=?0.65). FAIR-Tr is a questionnaire that has excellent internal consistency and test-retest reliability. The successful correlation with HADS and BHS supported its psychometric validity in terms of evaluating the fear in CIRD cases. We think that FAIR-Tr is a specific scale that can help to evaluate the disease- and treatment-related fears of the Turkish patients with CIRD and may be useful in both routine practice and clinical studies.
