TRAIL与羟基喜树碱联用协同杀伤人肺腺癌A549细胞

目的：探讨羟基喜树碱与肿瘤坏死因子相关凋亡诱导配体（tumor necrosis factor-related apoptosis inducing ligand，TRAIL）联用对肺腺癌A549细胞是否具有协同杀伤作用，并对其机制进行初步研究。方法：MTT法检测细胞毒性作用，流式细胞仪检测细胞凋亡和线粒体膜电位，Western blot分析bcl-2和bcl-xl蛋白水平变化。结果：单用100ng／mL TRAIL，4、40和400μg／mL羟基喜树碱对A549细胞杀伤率分别为13．9％、3．0％、23．4％和76．7％，联合用药的抑制率分别为43．6％、52．5％和83．1%。100ng／mL TRAIL和4μg/mL羟基喜树碱有协同作用，可使细胞线粒体膜电住降低，但不影响bcl-2和bcl-xl蛋白表达。结论：TRAIL与羟基喜树碱联用对肺腺癌A549细胞有明显的协同杀伤作用，其机制可能与羟基喜树碱降低A549细胞线粒体膜电位有关。     

Impact of EGFR expression on colorectal cancer patient prognosis and survival.

BACKGROUND: Epidermal growth factor receptor (EGFR) is overexpressed in many types of cancers, especially colorectal cancer (CRC), and seems to reflect more aggressive histological and clinical behaviors. The aim of this study was to evaluate EGFR immunohistochemical reactivity in CRC biopsies, and to analyze its relationship with various histological and clinical characteristics and survival. PATIENTS AND METHODS: A composite EGFR score, obtained by multiplying the grade (% positive cells) by the intensity of labeling (0-9) was used to define patients with low or high EGFR expression whose clinicopathological features were then compared. Univariate tests and multivariate Cox proportional hazards model were applied for data analysis. RESULTS: Tissue sections from 150 CRC patients with a median follow-up of 40 months were examined. Median patient age at diagnosis was 70 years (range 38-89 years). EGFR reactivity was positive for 143 patients (97%) and high for 118 (80%). According to multivariate analysis, EGFR overexpression was significantly associated with tumor stage, with a higher percentage of EGFR overexpression in T3 than T4 (P=0.003) and not with overall survival. CONCLUSIONS: EGFR was overexpressed in this CRC patient population and was significantly associated with TNM (tumor-node-metastasis) stage T3. In the context of a new therapeutic strategy using EGFR-targeted therapies, although EGFR remains a controversial prognostic factor, this expression-stage association may play a crucial role in a decision to initiate an adjuvant treatment.

脑AVM血管内栓塞治疗术后的护理

脑动静脉畸形(AVM)是脑实质内的血管在胚胎发育成型过程中受到阻碍,动静脉之间直接交通而形成的先天性疾病.以往传统的方法采用手术切除病灶,近年来,随着介入放射学的兴起,血管内栓塞已成为一种治疗脑AVM新的、独特的首选方法[1],栓塞治疗后的护理是保证栓塞治疗成功的关键,我科2003年1月～2006年5月行脑AVM血管内栓塞治疗共36例,取得较好的治疗效果,现将护理体会总结如下.     

口服红藤汤治疗炎性肠梗阻的效果观察

炎性肠梗阻多因腹部手术、炎症、损伤、出血、异物等所致,临床以腹部手术后多见,约占各类肠梗阻的20%～40%[1]。术后疼痛、不愿活动,依赖心理加重,均能引起肠蠕动减慢,肠粘连加重导致肠功能延迟恢复,继而引起炎性肠梗阻。2005年1月～2006年6月我科应用红藤汤口服,缓解炎性肠梗阻的肠功能恢复效果良好。现报告如下。对象和方法研究对象选择2005年1月～2006年6月我科住院急性阑尾炎伴穿孔,胃切除,结、直肠癌手术,胆道术后出现炎性肠梗阻病人40例,其中男22例,女18例,年龄18～39岁,平均28±4.8岁,随机分为实验组和对照组,每组20例。方法实验组及…     

Effectiveness of Scapular Stabilization Versus Non-Stabilization Stretching on Shoulder Range of Motion,a Randomized Clinical Trial

BackgroundPrevious research has demonstrated the benefits of both stabilization and non-stabilization of the scapula during stretching in individuals with posterior shoulder tightness, but limited evidence exists in patients with shoulder pain.Hypothesis/PurposeThe aim of this study was to determine the effect of stabilized scapular stretching on patients with shoulder pain. The primary hypothesis of this study is that stabilized scapular stretching will improve glenohumeral motion and pain compared to non-stabilized stretch program. A secondary hypothesis of this study is that stabilized scapular stretching will produce greater improvement in function compared to the non-stabilized stretching program.Study DesignRandomized Clinical TrialMethodsSixteen patients with sub-acromial pain associated with tendinopathy and associated pathologies presenting to physical therapy were randomized into two groups (stabilized or non-stabilized scapular stretching). Baseline pain and range of motion were measured prior to and following each treatment session for three visits that occurred over the course five to seventeen days depending on the patients availability. The dependent measurements were stabilized horizontal adduction, stabilized internal rotation, stabilized shoulder flexion, non-stabilized shoulder flexion, and current pain level.ResultsPatients in the scapular stabilization stretching group increased horizontal adduction 40° (CI₉₅ 31, 48°) compared to the non-stabilization stretching group increase of 8° (CI₉₅ 0, 17°) over the course of the three treatments (p<0.001). Similarly, the stabilized stretching group increased internal rotation 48° (CI₉₅ 26, 69°) compared to the non-stabilized stretching group increase of 26° (CI₉₅ 4, 48°) (p=0.001). Pain decreased in the stabilized stretching group by 1.4 points (CI₉₅ -0.4, 3.2) but increased slightly in non-stabilized group by -0.5 points (CI₉₅ -2.3, 1.3) which was not a clinically meaningful change. (p=0.03)ConclusionStabilized scapular stretching was more effective than non-stabilized stretching at gaining shoulder mobility in patients with shoulder pain. Benefits were immediate and sustained between treatment sessions. Stretching interventions improved range of motion but had limited effect on shoulder pain.Level of Evidence2     

Probenecid Inhibits Respiratory Syncytial Virus (RSV) Replication

RNA viruses like SARS-CoV-2, influenza virus, and respiratory syncytial virus (RSV) are dependent on host genes for replication. We investigated if probenecid, an FDA-approved and safe urate-lowering drug that inhibits organic anion transporters (OATs) has prophylactic or therapeutic efficacy to inhibit RSV replication in three epithelial cell lines used in RSV studies, i.e., Vero E6 cells, HEp-2 cells, and in primary normal human bronchoepithelial (NHBE) cells, and in BALB/c mice. The studies showed that nanomolar concentrations of all probenecid regimens prevent RSV strain A and B replication in vitro and RSV strain A in vivo, representing a potential prophylactic and chemotherapeutic for RSV.
