Objective To investigate the clinical and pathological features of primary hepaticepithelioid hemangio endothelioma (EHE) and try to improve the understanding and diagnosis of this disease.Methods From January 2007 to January 2013,the data of 17 patients with hepatic EHE were retrospectively analyzed,which included clinical,pathological and radiological characteristics,treatment and survival condition of these patients.Results Among 17 cases of hepatic EHE,there were 11 female and six male with the mean age of 46.2 years.Seven patients had right upper quadrant pain of dull pain in liver and the left 10 cases were without any symptoms.The liver function of most patients (15 cases) was normal.The admission diagnosis was mostly misdiagnosed as hepatocellular carcinoma (metastatic liver carcinoma six cases,primary liver carcinoma four cases).Extrahepatic metastasis was found in three patients before operation.The major lesion of the tumor was multiple nodules (10 cases) and most of which were under liver capsule.Retraction of the liver capsule was found in the imaging examination.The features of pathology were intracellular lumen and vacuoles formed in small cells,in which single or couple red blood cells could be found.Nuclear deviation was found in single tumor cell which looked like signet ring cells.The results of immunohistochemistry indicated the positive rate of factor vimentin (4/5) antigen and CD34 (15/17) was high.Surgical resection (14 cases) was the main treatment of hepatic EHE.Fourteen patients were still alive followed up for two to 72 months after operation.Conclusions The incidence of hepatic EHE is low,and it was susceptible to middle aged women and without obvious symptom.No obvious abnormality is found in laboratory examination.Surgical resection is the main treatment which enabled a good prognosis.

Objective To investigate the effect of exogenous murine interleukin-18 (IL-18) on early mouse collagen Ⅱ -induced arthritis (CIA). Methods Mice were injected intraperitoneallg IL-18 (0.2 μg/d) combination with IL-10 (0.1 μg/d), IL-4 (0.1 μg/d) and IL-12 (0.1 μg/d) daily for five days before the onset of CIA. The arthritis response was monitored visually by macroscopic scoring. Reverse transcription -polymerase chain reaction (RT-PCR) was employed to determine the mRNA expression of cytokine in patella with adjacent synovium in CIA mouse. Histology of knee was examined to assess the occurrence of cartilage destruction and bone erosion. Wilcoxon rank test was selected. Results IL-18/IL-4 treatment could slightly suppress the macroscopic score of arthritis, but a more pronounced amelioration was found in mice treated with the combination of IL-18 and IL-10 during early treatment. On 38 days after immunizatian macroscopic score in treated group (0.12±0.20) was significantly improves than in the control group (0.29±0.19, P<0.05). This resulted in both the suppression of macroscopic signs of inflammation and the reduction of cellular infiltrates in the synovial tissue, which provided the protection against cartilage destruction. Moreover, the expression of Thl cytokines [IL-18 (0.22±0.06), IL-12 (0.14±0.05)] and inflammatory cytokine [IL-6 (0.22±0.11)] was greatly inhibited both in the synovial tissue and in the articular cartilage in the treatment groups compared with those in the control groups (P<0.05). However, the mRNA levels of Th2 cytokines [IL-10 (6.35±0.12), IL-4 (3.57±0.13)] were up-regulated after IL-18/IL-10 treatment (P<0.05). Moreover, IL-18R (0.40±0.15) levels were down-regulated compared with those in the control group (P<0.05). T-bet mRNA levels were decreased in IL-18/IL-10 compared with the control group, and GATA-3 mRNA (5.71±0.11) levels were significantly higher than those in the control group (P<0.05). Conclusion Low dose IL-18/IL-10 treatment can inhibit Th1 cytokines expression and induce Th2 cytokines expression, which may be mediated not only by inhibiting Th1 responses through IL-18/IL-18R mechanism, but also by inducing anti-inflammatory mediators such as IL-10 and IL-4 through a GATA-3-dependent mechanism.

Objective To investigate the effect of exogenous murine interlukin-18 (mIL-18) on early and established murine coUagen-induced arthritis (CIA). Methods Mice were injected intraperitoneally with IL-18 (0.2 μg/mouse) daily for 5 days before or after the onset of CIA. The response was monitored visually by macroscopic scoring. Reverse transcription-polymerase chain reaction (RT-PCR) was employed to determine the mRNA expression of cytokines in patella with adjacent synovium in CIA mouse. Histolpgy of knee synovium was used to assess the occurrence of cartilage destruction and bone erosions. Results IL-18 alone had no effect on macroscopic score, occurrence of arthritis, advancement of histology on early stage of CIA. Moreover, expression of Th 1 cytokines and Th2 cytokines in the synovial tissue and" articular cartilage remained unchanged compared with the control group, however, a pronounced progression of histology was found in mice treated with IL-18 in estabhshed CIA. Forty-three days after immunization, the macroscopic score in the treated group (0.33±0.11 ) was significantly improved than in the control group (0.25±0.09) (P<0.05). Moreover, the mRNA levels of IL-10 and IL-18BP both in the synovial tissue and in the articular cartilage in the treated groups decreased significantly than those in the control groups (P<0.05). Conclusion Low dose mIL-18 alone has no effect on early stage CIA. But pronounced exacerbation is found in mice treated with IL-18 on established arthritis, which supports that IL-18 initiates this effect by inhibiting IL-10 and IL-18 BP.

Objective To understand the epidemiological characteristics of HIV infection in voluntary blood donors in Liuzhou city to provide the basis for the blood donation recruit launched by the blood collection and tranfusion service agencies and reduce the risk of transfusion transmitted HIV.Methods The epidemiological investigation on the voluntary unpaid blood donors infected with HIV during 2008-2012 was performed for analyzing the infection characteristics.Results HIV infection in blood donors in Liuzhou city had no statistical difference between different years (P >0.05);the differences in different sexes,age groups,married and unmarried persons had statistically significant differences (P <0.01 );the education background less than middle school ac-counted for 52.94%;56.21% of the infectors were the sexual transmission.Conclusion HIV infection in voluntary unpaid blood donors in Liuzhou city is dominated by young adult men and the persons with the education level less than junior high school,and the heterosexual transmission is predominant.The donor recruitment work should pertinently exclude the persons of high-risk be-havior and collect blood in low risk population as far as possible.

0. 05, respectively). Conclusion The results suggest that the combination measurement of serum levels of IV C, LN and sVCAM-1 in DR patients might better evaluate the development process of diabetic mi-croangiopathy, and be of help for early diagnosis and therapy of diabetic microangiopathy. Serum levels of IVC, LN and sVCAM-1 in DR patients may be reliable clinical markers for assessing the severity and prognosis of diabetic retinopathy.
