急性心肌梗死自溶现象及其影响因素分析

目的分析急性心肌梗死（AMI）梗死相关血管（IRA）的自溶（SR）现象,探讨SR现象的影响因素。方法连续观察205例未予静脉溶栓治疗,直接行急诊冠状动脉造影的AMI患者,根据TIMI血流分为自溶组（前向血流TIMI 2-3级）和非自溶组（前向血流TIMI 0-1级）,分析其临床和造影特点,并寻求发生SR的影响因素。结果自溶组共49例（23.9%）。与非自溶组比较,一般临床情况差异无统计学意义（P〉0.05）,但自溶组发生梗死前心绞痛的比例较高（38.8%比22.4%,P〈0.05）。而非自溶组多支病变和存在侧支循环的比例高于自溶组（P〈0.05）。Logistic回归分析则提示多支病变和侧支循环是发生SR现象的独立影响因素。结论SR是AMI患者较常见的现象,其独立影响因素是多支病变和侧支循环。     

军事训练伤致腕部尺骨撞击综合征的非手术治疗

目的探讨军事训练伤致尺骨撞击综合征的非手术治疗方法及效果。方法2001年12月—2005年12月,对因训练伤后确诊为腕部尺骨撞击综合征的43例患者给予腕部外固定、关节内注射、局部理疗及口服非甾体类抗炎药物治疗。结果非手术治疗后,19例(44.2%)患者腕部、手部症状出现显著改善,患者恢复伤前工作及训练;13例(30.2%)症状改善,但不能恢复原有工作及训练,仍有11例(25.6%)腕部症状无改善,总有效率为74.4%。结论对训练伤导致尺骨撞击综合征非手术治疗有效,早期诊断、早期治疗是保证疗效的关键。     

伊曲康唑治疗着色芽生菌病后出现暂时性增生性皮疹一例

患者,男,67岁。鼻部增生性斑块4个月,有外伤史。实验室检查：组织病理可见真菌孢子,真菌镜检可见硬壳小体,真菌培养与菌种鉴定为卡氏枝孢瓶霉。予伊曲康唑、热敷治疗,患者治疗第1个月后原皮损部位出现的增生性皮疹,继续原治疗方案3个月,增生性皮疹萎缩,基本痊愈。出现增生性皮疹的原因猜测为伊曲康唑治疗后,皮损部位的真菌细胞膜功能受损,大量异种蛋白被机体识别,加重了局部的炎症反应,具体原因还需要进一步研究。     

The altering in sensory sensitivity: a current issue of female breast surgery

Breast surgery is an important treatment for women with malignant breast diseases. In addition to breast appearance, the integrity of breast function is increasing in patients with breast diseases. As the basis of breast physiological function, breast skin sensitivity is important to the quality of life of patients after surgery. Breast skin sensitivity gives the patient a “real” breast feeling. The sensory recovery after breast surgery has also become one of the important goals of breast surgery. In this review, we aim to discuss the research progress on recovery of breast skin sensitivity after different treatment modalities for breast disease.     

Vitamin D Enhances Neutrophil Generation and Function in Zebrafish (Danio rerio)

Vitamin D (VD) is a major regulator of calcium metabolism in many living organisms. In addition, VD plays a key role in regulating innate and adaptive immunity in vertebrates. Neutrophils constitute an important part of the first line of defense against invading microbes; however, the potential effect of VD on neutrophils remains elusive. Thus, in this study zebrafish in different developmental stages were utilized to identify the potential role of VD in the basal homeostasis and functions of neutrophils. Our results showed that addition of exogenous VD₃ promoted granulopoiesis in zebrafish larvae. Reciprocally, neutrophil abundance in the intestine of adult zebrafish with a cyp2r1 mutant, lacking the capacity to 25-hydroxylate VD, was reduced. Moreover, VD-mediated granulopoiesis was still observed in gnotobiotic zebrafish larvae, indicating that VD regulates neutrophil generation independent of the microbiota during early development. In contrast, VD was incapable to influence granulopoiesis in adult zebrafish when the commensal bacteria were depleted by antibiotic treatment, suggesting that VD might modulate neutrophil activity via different mechanisms depending on the developmental stage. In addition, we found that VD₃ augmented the expression of il-8 and neutrophil recruitment to the site of caudal fin amputation. Finally, VD₃ treatment significantly decreased bacterial counts and mortality in zebrafish infected with Edwardsiella tarda (E. tarda) in a neutrophil-dependent manner. Combined, these findings demonstrate that VD regulates granulopoiesis and neutrophil function in zebrafish immunity.     

Proteomic analysis of the effects of caffeine in a neonatal rat model of hypoxic‐ischemic white matter damage

AimWhite matter damage (WMD) is the main cause of cerebral palsy and cognitive impairment in premature infants. Although caffeine has been shown to possess neuroprotective effects in neonatal rats with hypoxic‐ischemic WMD, the mechanisms underlying these protective effects are unclear. Herein, proteins modulated by caffeine in neonatal rats with hypoxic‐ischemic WMD were evaluated.MethodsWe identified differential proteins and performed functional enrichment analyses between the Sham, hypoxic‐ischemic WMD (HI), and HI+caffeine‐treated WMD (Caffeine) groups. Confirmed the changes and effect of proteins in animal models and determined cognitive impairment via water maze experiments.ResultsIn paraventricular tissue, 47 differential proteins were identified between the Sham, HI, and Caffeine groups. Functional enrichment analyses showed that these proteins were related to myelination and axon formation. In particular, the myelin basic protein (MBP), proteolipid protein, myelin‐associated glycoprotein precursor, and sirtiun 2 (SIRT2) levels were reduced in the hypoxic‐ischemic WMD group, and this effect could be prevented by caffeine. Caffeine alleviated the hypoxic‐ischemic WMD‐induced cognitive impairment and improved MBP, synaptophysin, and postsynaptic density protein 95 protein levels after hypoxic‐ischemic WMD by preventing the HI‐induced downregulation of SIRT2; these effects were subsequently attenuated by the SIRT2 inhibitor AK‐7.ConclusionCaffeine may have clinical applications in the management of prophylactic hypoxic‐ischemic WMD; its effects may be mediated by proteins related to myelin development and synapse formation through SIRT2.     

A Novel Herbal Extract Blend Product Prevents Particulate Matters-Induced Inflammation by Improving Gut Microbiota and Maintaining the Integrity of the Intestinal Barrier

Air pollutants of PM2.5 can alter the composition of gut microbiota and lead to inflammation in the lung and gastrointestinal tract. The aim of this study was to evaluate the protective effect of a novel herbal extract blend, FC, composed of Lonicera japonica extract, Momordica grosvenori extract, and broccoli seed extract, on PM2.5-induced inflammation in the respiratory and intestinal tract. A549 cells and THP-1 cells, as well as C57BL/6 mice, were stimulated with PM2.5 to establish in vitro and in vivo exposure models. The models were treated with or without FC. The expression of inflammatory cytokines and tight junction proteins were studied. Proteomic analysis was performed to elucidate mechanisms. Mouse feces were collected for gut microbiota analysis. FC was shown to modulate the upregulation of pro-inflammatory cytokines mRNA expression in A549 and THP-1 cells and downregulated tight junction proteins mRNA expression in A549 cells due to PM2.5 stimulation. In animal models, the decreased expression of the anti-inflammatory factor il-10, tight junction protein ZO-1, and the elevated expression of COX-2 induced by PM2.5 were improved by FC intervention, which may be associated with zo-1 and cox-2 signaling pathways. In addition, FC was shown to improve the gut microbiota by increasing the abundance of beneficial bacteria.
