血清肝细胞生长因子测定对急性冠脉综合征患者的临床意义

目的探讨急性冠脉综合征(ACS)患者血清肝细胞生长因子(HGF)水平变化的临床意义。方法入选59例ACS患者(急性心肌梗死组n=36,发病12h以内;不稳定型心绞痛组n=23)于入院时肝素注射前取静脉血,通过酶联免疫法测定血清HGF浓度。同时对与之性别及年龄相匹配的27例正常人测定相同指标。结果血清HGF浓度在AMI组[(1572.9±229.0)pg/ml]、UAP组[(899.2±63.9)pg/ml]较正常对照组[(619.5±31.1)pg/ml]明显增高;AMI发病3h内血清HGF水平也比正常对照组增高[(893.2±61.6)pg/mlvs(619.5±31.1)pg/ml];A-MI组血清HGF浓度与入院时cTnI、CK-MB及CK-MB峰值均无相关性;ACS患者血清HGF浓度与入院时CRP呈显著相关性。结论ACS患者血清HGF浓度增高,且与疾病的严重性呈正比;HGF的产生可能与ACS的炎症反应有关;血清HGF有可能成为临床上诊断早期AMI的一个新指标。

VEGF is causative for pulmonary hypertension in a patient with Crow-Fukase (POEMS) syndrome

We report a case of Crow-Fukase (POEMS) syndrome associated with pulmonary hypertension (PH). In this case, the concentration of vascular endothelial growth factor (VEGF) was extremely high in the serum, and the levels of IL-1beta, IL-6, TNF-alpha, and thiamine, which were thought in past reports to be mediators of PH in Crow-Fukase syndrome, were normal. After prednisolone therapy, PH disappeared with a dramatic decrease in serum VEGF. Our results suggest that VEGF is closely correlated with PH in Crow-Fukase syndrome.     

血清白介素15水平与冠心病冠状动脉病变严重程度的相关性

目的 分析血清白介素15(interleukin15,IL-15)水平与冠心病冠状动脉病变严重程度的相关性。方法 选取我院心内科行冠脉造影检查的患者270例,采用 Gensini评分评估冠脉狭窄严重程度,将患者按冠脉狭窄程度分为:正常组、轻度狭窄组、中度狭窄组和重度狭窄组（正常组Gensini=0;轻度组:041）。所有受试者接受问卷调查、体格测量、生化指标、收集各受试者临床资料及采用ELISA测定血清IL-15的浓度。运用多种统计分析方法,采用回归模型校正年龄,体质量指数,血脂,C反应蛋白,高血压病以及糖尿病等混杂因素,分析IL-15水平与冠心病冠脉病变严重程度的相关性。结果 与冠脉造影正常组相比,冠脉狭窄患者血液中IL-15水平显著高于冠脉正常人群,并随冠状动脉狭窄的严重程度增加有逐渐增高的趋势〔正常:(6.7±2.0)ng/L,轻度狭窄:(11.9±3.1) ng/L,中度狭窄:(18.3±3.2) ng/L,重度狭窄:(24.4±4.0) ng/L;P<0.01〕。IL-15与Gensini评分呈正相关（r=0.572,P<0.01）,这种关系在校正年龄,体质量指数,C反应蛋白,血脂,高血压病以及糖尿病等混杂因素后依然存在,是独立的相关因素。结论 血清IL-15水平与冠脉狭窄程度呈正相关,血清IL-15水平是冠心病冠脉病变严重程度的独立相关因素。     

Vascular endothelial growth factor in patients with psoriatic arthritis

OBJECTIVE: To determine the levels of vascular endothelial growth factor (VEGF) in patients with active psoriatic arthritis, patients with inactive psoriatic arthritis, and healthy controls. Serum VEGF levels were correlated with clinical and laboratory features in patients with active psoriasis arthritis. METHODS: Serum samples from 14 patients with active psoriatic arthritis, 14 patients with inactive psoriatic arthritis, and 9 healthy controls were investigated. VEGF levels in the serum were measured using a sensitive sandwich ELISA. RESULTS: The mean serum VEGF concentration in patients with active PA was 394.4 pg/ml (394 +/- 171.8), in patients with inactive PA 200.4 pg/ml (200.4 +/- 115.7), and in healthy subjects 214.3 pg/ml (214.3 +/- 162.1). Patients with active psoriasis arthritis had significantly higher levels of VEGF compared to patients with inactive psoriasis arthritis and healthy individuals (p > 0.001). In contrast, VEGF levels were comparable in patients with inactive psoriatic arthritis and controls (p =0.659). Furthermore, in patients with psoriatic arthritis, VEGF levels were positively correlated with ESR, HAQ, PASI and VAS. CONCLUSION: VEGF levels may be regarded as a good indicator of active psoriasis arthritis.

目的：研究先天性心脏病（CHD）患者血清氨基末端脑钠肽前体（NT-proBNP）浓度与肺动脉平均压（mPAP）的相关性.方法：62例行导管封堵治疗的CHD患者根据mPAP水平被分为四组：CHD不合并肺动脉高压（PAH）组（26例）、CHD合并轻度PAH组（17例）、CHD合并中度PAH组（12例）、CHD合并重度PAH组（7例）,同期选择20例健康体检者作为健康对照组.比较各组介入封堵术前后24h及3个月时的血清NT-proBNP浓度的变化并分析介入封堵术前NT-proBNP浓度与mPAP的关系.结果：与健康对照组相比,术前各CHD组血清NT-proBNP水平明显升高,且随着mPAP升高而显著升高[健康对照组（34.0±16.8）pg/ml比CHD无PAH组（68.0±20.2）pg/ml比轻度PAH组（116.7±43.5） pg/ml比中度PAH组（273.1±64.2）pg/ml比重度PAH组（326.5±50.2） pg/ml,P均＜0.01];直线相关分析显示：62例CHD患者术前血清NT-proBNP浓度与mPAP呈正相关（r=0.604,P=0.002）.各组术后24hNT-proBNP浓度较术前升高,但只有CHD不合并PAH组有统计学差异[（98.9±22.1） pg/ml比（68.0±20.2） pg/ml,P＜0.05],4组术后3个月NT-proBNP浓度较术前均有显著降低（P均＜0.01）.结论：先天性心脏病患者血清NT-proBNP浓度随肺动脉压力升高而逐渐升高,可作为先心病患者肺动脉高压程度以及预后判断的一个指标.     

Vascular endothelial growth factor levels in the serum and synovial fluid of patients with rheumatoid arthritis.

OBJECTIVE: To determine the vascular endothelial growth factor (VEGF) concentrations in serum and synovial fluid (SF) from patients with rheumatoid arthritis (RA) and to search for relationships between VEGF levels and clinical and laboratory variables. METHODS: We measured VEGF levels using an enzyme-linked immunosorbent assay. Serum samples were obtained from 99 RA patients, 49 osteoarthritis (OA) patients, and 80 normal controls. Paired samples of serum and SF were collected from 32 patients with RA and 15 with OA. RESULTS: The mean serum VEGF concentration was 590.1 pg/ml for RA patients, 286.7 pg/ml for OA patients, and 265.8 pg/ml in controls. The serum VEGF concentration was significantly higher in the RA patients than in the OA patients or the controls (both p < 0.001). Furthermore, the VEGF levels in SF from RA patients were significantly higher than in SF from OA patients (p = 0.017). However, there was no correlation between VEGF levels in serum and SF from the same RA patients. The serum VEGF concentration was correlated with the ESR, serum CRP concentration, serum rheumatoid factor, number of tender and swollen joints, Modified Health Assessment Questionnaire, and patient and physician global assessments of disease activity in RA patients. CONCLUSION: These results suggest that VEGF level is related to RA disease activity, suggesting that VEGF may play some role in the pathogenesis of RA.     

POEMS syndrome diagnosed by detection of M-protein on immunofixation and increased level of vascular endothelial growth factor

A 48-year-old male with Castleman disease developed symptoms typical of POEMS syndrome (polyneuropathy, organomegaly, endocrinopathy, monoclonal-protein and skin changes) but M-protein was not detected by immunoelec-trophoresis. He was diagnosed as having POEMS syndrome based on IgA-λ detected by immunofixation electrophoresis and an increased level (3,170 pg/ml) of vascular endothelial growth factor (VEGF). After diagnosis, the patient underwent autologous peripheral blood stem cell transplantation safely and remained relapse-free and in good condition for 15 months. This case suggests that immunofixation electrophoresis and detection of elevated serum VEGF level are useful methods for earlier diagnosis of POEMS syndrome.     

血清VEGF水平与冠状动脉病变程度的临床研究

冠心病严重威胁着人类的健康,国内外研究证实血管内皮细胞生长因子（vascular endothelial growth factor,VEGF）及碱性成纤维细胞生长因子（basic fibroblast growth factor,bFGF）有强烈的促血管新生作用,能促进缺血心肌侧枝血管明显增加,在冠心病的治疗方面有广阔的临床应用前景。     

A prospective phase II study of low dose lenalidomide plus dexamethasone in patients with newly diagnosed polyneuropathy,organomegaly, endocrinopathy,monoclonal gammopathy,and skin changes (POEMS) syndrome

Polyneuropathy, organomegaly, endocrinopathy, monoclonal gammopathy, and skin changes (POEMS) syndrome is a rare plasma dyscrasia without standard treatment. This phase II prospective trial evaluates the safety and response of 12 cycles of low dose lenalidomide (10 mg) plus dexamethasone (Rdex) in patients with newly diagnosed POEMS syndrome. Forty‐one patients (28 men) were enrolled and the median age at diagnosis was 49 years (range, 21‐70 years). Twenty‐one patients (46%) achieved complete hematologic response and the neurologic response rate was 95%. The median serum vascular endothelial growth factor (VEGF) declined from 5155 pg/mL (range, 534‐14 328 pg/mL) to 832 pg/mL (95‐6254 pg/mL) after therapy. The overall VEGF response rate was 83%, and the median time to response was 2 months, with a mean VEGF reduction of 43% at the first month. In terms of clinical response, Rdex substantially relieved extravascular volume overload, organomegaly, and pulmonary hypertension. No treatment‐related deaths occurred and no patients suffered from lenalidomide‐related grade 3 or above adverse events. After a median follow‐up of 34 months, median overall survival (OS) and progression‐free survival (PFS) were not reached, with an estimated 3‐year OS and PFS of 90% and 75%, respectively. In conclusion, Rdex was active with high hematologic, VEGF and organ response rate and well tolerated for patients with newly diagnosed POEMS syndrome. This trial was registered at www.clinicaltrials.gov as #NCT01816620.
