不是一句话的事儿

小张的同事A常搭小张的车回家，每次，小张总是先把A送到家才回自己家。返程时，一接到小张的电话，A就说：“哥，我在家等你，你来接我吧。”他们两家之间有一段不太长的路程，小张总是到楼下接A。     

综合心理干预对“120”急救人员生活质量的影响

[目的]探讨综合心理干预对"120"急救人员生活质量的影响。[方法]选择韶关市"120"急救人员120名作为研究对象,随机分为干预组和对照组,对干预组成员实施综合心理干预措施,对照组成员不予干预。采用症状自评量表(SCL-90)、特质应对方式问卷(TCSQ)、社会支持评定量表(SSRS)和急救人员工作生活质量调查表评估两组"120"急救人员的心理健康状况水平、应对方式、社会支持及生活质量情况。比较两组抑郁和焦虑发生情况。[结果]干预组症状自评分、社会支持评分、生活质量评分优于对照组,抑郁、焦虑程度轻于对照组(P0.05)。[结论]综合管理措施的实施有利于促进身心健康,提高"120"急救人员的生活质量。     

卵巢囊性畸胎瘤并T细胞源性淋巴瘤一例临床病理分析

目的 分析罕见病例卵巢囊性畸胎瘤（MCT）并T细胞源性淋巴瘤的病理学特点及临床治疗现状.方法 用影像学、组织病理学、免疫组织化学方法,结合文献对1例MCT并T细胞源性淋巴瘤进行观察分析.结果 患者,女,63岁.左侧卵巢肿瘤12 cm＆#215;12 cm＆#215;8 cm,多房,多为实性灰白色,囊内有脂质、毛发.镜下见囊壁有大小一致的肿瘤细胞弥散分布,细胞体积小,胞质少,核深染;另见鳞状上皮、毛囊、皮脂腺和软骨;鳞状上皮及软骨间瘤细胞浸润.免疫组织化学瘤细胞：Vim＋＋＋、Ki-67＋（＞75％）、LCA＋＋＋、CD43＋＋＋、CD3＋＋,其余标志物为阴性.结论 该例MCT上皮、软骨成分为良性,小细胞肿瘤成分组织学和免疫组织化学证实为T细胞淋巴瘤,多系MCT恶变,尚属罕见.该肿瘤的早期诊断、及时手术切除、术后酌情追加化疗、放疗对患者的预后至关重要.     

miR-221/miR-222与肿瘤

肿瘤的发生是一个多因素参与的阶段性演进过程,研究发现mi R-221/mi R-222在多数肿瘤中的表达失调,通过负调控抑癌基因或癌基因的表达,促进或抑制肿瘤的发生、发展。现就mi R-221/mi R-222在肿瘤中的表达、作用及其临床意义作一综述,并探讨mi R-221/mi R-222在肿瘤治疗中的潜在价值。     

良性前列腺增生合并2型糖尿病患者治疗选择的临床研究

目的:探讨比较经尿道前列腺电切术和口服药物治疗良性前列腺增生合并2型糖尿病患者的有效性和安全性。方法:86例良性前列腺增生合并2型糖尿病患者,随机分成经尿道前列腺电切手术组(A组,n=46)和口服药物组(B组,n=40)。分别观察两组治疗1年后疗效与并发症,分别测定1年前后各患者最大尿流率(Qmax)、膀胱残余尿量(postvoid residualurine volume,PRV)及国际前列腺症状评分(International Prostate Symptom Score,IPSS)、生活质量评分(Quality of life score,QOL)。结果:两组患者年龄及治疗前Qmax、PRV、IPSS、QOL比较均无统计学差异(P>0.05)。1年后两组比较,A组疗效及并发症,最大尿流率、IPSS及QOL明显优于B组,差异有统计学意义(P<0.01);但两组膀胱残余尿量差异无统计学意义(P>0.05)。结论:经尿道前列腺电切术较口服药物能够明显改善患者膀胱梗阻,降低尿路感染及尿潴留风险,延缓膀胱收缩功能障碍。     

生肌玉红膏对增生性瘢痕的抑制作用

BACKGROUND: Shengjiyuhong ointment has been reported to inhibit hypertrophic scarring. OBJECTIVE: To verify the effects of Shengjiyuhong ointment on hypertrophic scarring of in a rabbit ear model. METHODS: Each ear of thirty-six Japanese rabbits was used to make four 1-cm-diameter circular full-thickness skin wounds with the entire perichondrium removed. Finally, 288 wounds were made and randomly divided into 6 groups: model, negative control (no drugs were administered), low-, moderate-, high-crude herbal dose drugs (Shengjiyuhong ointment was administered topically at concentrations of 8.39%, 25.18%, and 75.54%), and positive control (recombinant bovine basic fibroblast growth factor was administered topically). Shengjiyuhong ointment was administered twice daily till wound healing. The wounds were evaluated by the Vancouver scar scale (VSS). Scar elevation index (SEI) of scar specimens was calculated under a microscope at 40× magnification. mRNA expression levels of type I and III collagen, connective tissue growth factor, fibronectin, and α-smooth muscle actin (α-SMA) were determined by fluorescent quantitative PCR. Protein expression levels of type I and III collagen and α-SMA were detected by western blot assay. α-SMA immunoreactivity was determined by immunofluorescent staining. RESULTS AND CONCLUSION: VSS scores and SEI were significantly increased in each group at 30 days (P < 0.05). VSS scores and SEI were significantly decreased in the moderate- and high-crude herbal dose drug groups and positive control groups compared with the model, negative control, and low-crude herbal dose drug groups (P < 0.05 or P < 0.01). mRNA expression levels of type I and III collagen, connective tissue growth factor and fibronectin, and protein expression levels of type I and III collagen and α-SMA were significantly inhibited after moderate-crude herbal dose Shengjiyuhong ointment and positive drug treatment (P < 0.01). These findings suggest that Shengjiyuhong ointment can reduce hypertrophic scars by inhibiting fibroblast proliferation and collagen deposition. 中国组织工程研究杂志出版内容重点：组织构建;骨细胞;软骨细胞;细胞培养;成纤维细胞;血管内皮细胞;骨质疏松;组织工程     

STAT3与P-STAT3在转基因AD小鼠脑组织中的表达及意义
