慢性肝病和原发性肝癌患者血清白细胞介素-8水平及其意义

目的 探讨IL-8在慢性肝病和原发性肝癌发病机理中的作用及与临床变化的关系。方法 对住院治疗的80例各型肝病患者和14例健康人抽取静脉血5ml,分离血清并置于-40℃之中,采用ELISA法对血清进行IL-8检测。结果 不同类型肝病患者血清中IL-8水平差异均有显著性。慢性病毒性肝炎重型IL-8水平为(75.80±33.39)μg/L,原发性肝癌IL-8水平为(89.54±13.24)μg/L,与对照组比较t值分别为10.48、4.01,P<0.01。结论 血清IL-8水平的升高与各类肝病患者病情轻重及预后有密切的关系。在慢性病毒性肝炎和原发性肝癌患者血清中,IL-8水平越高,病情越重,预后越差,病死率越高。

Primary hepatic sarcomatoid carcinoma: clinical features and prognosis of 28 resected cases

Purpose

Primary hepatic sarcomatoid carcinoma (SC) is an extremely rare malignancy composed of both carcinomatous and spindle cell sarcomatous components. Our aim was to clarify the clinical features and prognosis of patients with this disease.

Methods

Between January 1996 and August 2012, 28 patients were histologically diagnosed as primary hepatic SC after surgical resection. Their demographic, clinicopathological, and survival data were retrospectively reviewed.

Results

There were 22 men (78.6 %) and 6 women (21.4 %), with a median age of 53 years (range 29–73 years). The median overall survival was 11.5 months, and the 1-, 2-, and 3-year overall survival rates were 50, 21.4, 14.3 %, respectively. The patients who received radical resection had obviously better survival compared with those underwent palliative resection (15.6 vs. 7.6 months, P = 0.001). Multivariate analysis revealed that TNM stage [HR 8.737, 95 % CI 1.263–60.430, P = 0.042] and local invasion [HR 4.734, 95 % CI 1.382–16.220, P = 0.013] were independent risk factors for overall survival.

Conclusions

Primary hepatic SC is highly aggressive malignancy with extremely poor prognosis. Radical resection at an early stage may contribute to a relatively favorable prognosis for this uncommon disease.     

Fatigue in rheumatoid arthritis and its relation to interleukin-6 serum level

Patients and methodsThe study included 30 patients with RA diagnosed according to the 2010 ACR-EULAR classification criteria for RA and 15 healthy controls. Patients were included if they were above 18 years and fulfilled a score ?6 over 10 of the 2010 ACR-EULAR classification criteria for RA. Disease activity was assessed using 28 joint disease activity score (DAS28), erythrocytes sedimentation rate (ESR), C-reactive protein (CRP). Fatigue was assessed with the Bristol Rheumatoid Arthritis Fatigue Multidimensional Questionnaire (BRAF-MDQ) and serum IL-6 level was measured in patients and controls.ResultsThe BRAF-MDQ was significantly higher among patients (mean = 50.6 ± 15.2) than controls (mean = 7.8 ± 3.7) (p < 0.001). Patients’ mean IL-6 serum level was 35.05 ± 21.23 pg/ml and 4.72 ± 3.09 pg/ml among control subjects (p < 0.001). DAS 28 ranged between 4.33 and 7.67, mean 1st hour ESR was 43.57 mm and CRP was positive in 76.7% of patients. Significant correlations were found between BRAF-MDQ score and serum IL-6 level (r = 0.947, p < 0.001), ESR (r = 0.509, p < 0.001) as well as CRP positivity (r = 0.411, p = 0.005) in RA patients. Serum IL-6 level correlated with ESR (r = 0.463, p < 0.001) and CRP (r = 0.376, p = 0.01) among patients.ConclusionFatigue is a common symptom and scores higher among RA patients than healthy controls and should be measured in all RA patients with simple fatigue questionnaires matching with different cultures. Fatigue becomes more prominent as serum IL-6 level increases independently of the disease duration and activity.     

Achalasia secondary to carcinoma: manometric and clinical features

The clinical and diagnostic features of a secondary type of achalasia of the esophagus are described in seven patients with various types of malignancies. Patients with secondary achalasia presented with dysphagia of short duration and marked weight loss; mean age was 64 years. Esophageal manometry showed features identical to those of idiopathic primary achalasia: aperistalsis, poor lower esophageal sphincter relaxation, and elevated sphincter pressure. Endoscopy and barium swallow showed evidence of a tumor in only two cases. Various types of malignancies may produce a secondary form of achalasia that has diagnostic features identical to those of primary achalasia and is best identified by its clinical presentation.

Fecal egg output in relation to worm burden and clinical features in human opisthorchiasis

A study of the relation of fecal egg excretion to worm burden and clinical features was carried out in 45 opisthorchiasis patients who had no signs of biliary obstruction. The fecal egg excretion was consistent and correlated with the worm burden. Although there was no definite association between clinical signs and intensity of infection, mild hepatomegaly and thickened wall or dilatation of the gallbladder were found more commonly in heavily infected patients. Eosinophilia was observed more often than previous reports. Concomitant parasitic infections were found in 82% of the patients. After praziquantel treatment, egg counts increased greatly during the first few days then decreased to very low levels in 7 days.     

尿中白细胞介素─6测定与系膜增殖性肾炎病理改变相关分析

原发性肝癌临床特点分析

目的了解原发性肝癌(PHC)临床特点,为PHC的防治提供依据。方法采用回顾性调查方法,对310例PHC住院患者的临床资料进行分析。结果80%以上的患者以非特异性症状与体征就诊,12.26%因并发症、合并症或转移症状就诊,3.55%因体检异常就诊;在有病理诊断的病例中,肝细胞癌占70.7%(29/41);HBV感染率为81.61%,男性高于女性(P<0.01);AFP阳性率为70.5%,HBV感染者AFP阳性率明显高于非HBV感染者(P<0.01);2.9%具有血吸虫病史,33.23%有嗜烟、酒史;4.52%具有PHC家族史。结论HBV感染是PHC的主要病原学因素,嗜酒、吸烟及血吸虫病等也可能是肝癌的风险因素。积极预防和控制HBV感染流行,是减少PHC发生的关键所在;定期对健康人群尤其是高危人群进行B超、AFP等检测,早发现、早治疗是提高原发性肝癌生存率的关键。     

Location and type of gastric carcinoma in relation to pepsinogen I level in blood.

Serum pepsinogen I (PGI) levels were measured in 192 gastric carcinoma (GC) patients and 70 controls. Among GC patients serum PGI levels were not influenced by the following variables: age, sex, smoking, Borrmann's or Lauren's classification, tumor size, cellular differentiation, and layer of invasion. The mean serum PGI levels of tumors restricted to the body, antrum, or involving both areas were 64.8 +/- 37.6 ng/ml, 76.0 +/- 47.0 ng/ml, and 51.1 +/- 25.5 ng/ml, respectively (P < 0.005). Odds ratios of GC patients from the quartile of 262 serum PGI levels in the limits > or = 100 ng/ml, 70-99.9 ng/ml, 45-69.9 ng/ml, and < 45 ng/ml were 1.00, 0.76, 3.44, and 37.1, respectively (P < 0.001). The lower serum PGI levels of Chinese GC patients seem to be related to disease location rather than other characters of the tumor.
