Objective To investigate the hemodynamics of increasing portal venous pressure(PVP) in hepatocellular carcinoma patients complicated with hepatic arterioportal vein fistulas (HAPVF)and the diagnosis and therapy of intractable upper gastrointestinal hemorrhage caused by HAPVF.Methods One hundred and fifteen cases of hepatocellular carcinoma with upper gastrointestinal hemorrhage were checked by hepatic arteriography and were treated through orifices embolization in cases with severe HAPCF by coils and/or ethanol. Results Twenty-six out of 31 patients suffering intractable upper gastrointestinal hemorrhage have severe HAPVF(the main stem of portal veins are visible).However,there are only 15 patients with light HAPVF among the 84 patients who have mild upper gastrointestinal hemorrhage (the main stem of portal veins are invisible).After the embolization,all of the 26 patients who have severe HAPVF stopped bleeding.Among them,the main stem of hepatic arteries are occluded in 2 patients. Conclusion The existence of severe HAPVF should be taken into consideration when intractable upper gastrointestinal hemorrhage occurs in hepatocellular carcinoma patients,and it can be diagnosed through hepatic artery DSA.Orifice embolization is the most effective method for such kind of hemorrhage.

OBJECTIVETo observe the impacts of acupoint catgut embedding therapy and acupuncture-moxibustion therapy on the long-term efficacy and patient's life quality in the treatment of allergic rhinitis.

METHODSSixty-nine patients were randomized into the combined acupuncture-moxibustion and acupoint catgut embedding therapy group (combined therapy group, 36 cases) and an acupuncture-moxibustion group (33 cases). In the acupuncture-moxibustion group, acupuncture was applied at Yingxiang (LI 20), Shangyingxiang (EX-HN 8), Yintang (GV 29), Shangxing (GV 23), Tongtian (BL 7) and Zusanli (ST 36). Moxibustion was applied at Zusanli (ST 36), Feishu (BL 13), Dazhui (GV 14) and Fengmen (BL 12). In the combined therapy group, on the basis of the treatment as acupuncture-moxibustion group, the catgut embedding therapy was applied at Feishu (BL 13), Fengmen (BL 12), Pishu (BL 20), Shenshu (BL 23), Zhongwan (CV 12) and Qihai (CV 6). The treatment duration was 4 weeks in the two groups. The clinical efficacy of allergic rhinitis and rhinoconjunctivitis quality of life questionnaire (RQLQ) score were observed before and after treatment as well as in the 4-weeks follow-up after the end of treatment respectively.

RESULTSThe markedly effective rate was 72.7% (24/33) in the combined therapy group and 48.4% (15/31) in the acupuncture-moxibustion group after treatment. The efficacy was similar between the two groups (P > 0.05). It was 57.6% (19/33) in the combined therapy group and was 22. 6% (7/31) in the 4-week follow-up after treatment, indicating the long-term efficacy in the combined therapy group was superior to that in the acupuncture-moxibustion group (P<0. 05). Scores of RQLO after treatment and in 4-week follow-up after treatment in both groups were improved as compared with those before treatment (all P < 0.05). In 4-week follow-up, the improvements in sleep and affection in the combined therapy group were superior to the acupuncture-moxibustion group (3.27 +/- 3.23 vs 4.61 +/- 3.56, 3.48 +/- 3.67 vs 5.81 +/- 4.15, both P < 0.05).

CONCLUSIONThe acupoint catgut embedding therapy combined with acupuncture-moxibustion therapy are safe and effective in the treatment of allergic rhinitis and display the more roles in the long-term efficacy.

Objective To investigate the expression of Foxp3~+ lymphocytes in breast carcinoma tissues and their correlation with other pathological factors,and to investigate the mechanism of action of Treg cells.Methods The expression of Foxp3~+ lymphocytes in the breast cancer tissue and non-cancerous tissue was detected by flow cytometry (FCM) in 30 breast carcinoma patients, and its correlation with other pathological factors was statistically analyzed by multiple linear regression analysis.The expression of TGF-β and IL-10 in the lymphocytes infiltrated in breast cancer tissue and non-cancerous tissue was measured by immunohistochemistry, and their correlation with the expression of Foxp3~+ lymphocytes was statistically analyzed by linear correlation dependability analysis. Results There was significant difference in the expression of Foxp3~+ lymphocytes between the malignant and non-cancerous breast tissues(P<0.05),and it was positively correlated with the clinical stage,blood vessel invasion and the matter of axillary lymph node metastasis(P<0.05). The expression of IL-10 in the tumor infiltrating lymphocytes was positively correlated with the expression of Foxp3~+ lymphocytes(P<0.05).Conclusion The expression level of Foxp3~+ lymphocytes is correlated with invasion and metastasis of breast carcinoma, and the IL-10 secreted by Foxp3~+ lymphocytes may be involved in this effect.Foxp3~+ lymphocytes can be used as an assistant marker for prediction and new therpeutic target of breast cancer.

Objective To study the effects of oxymatrine as inhibitor of hemorrhagic fever with renal syndrome virus (HFRSV) infection in vitro and in vivo.Methods In vitro studies,a dose of oxymatrine without cytotoxicity and 76-118 strain of HFRSV was taken to treat Vero cells in three ways:①After treated with oxymatrine for 48 h,Vero cells were attacked by HFRSV at dilution of 10-1 ～ 10-6,respectively for 24 h before changing to maintenance medium; ②Vero cells were first attacked by HFRSV of 10-1 ～ 10-6 dilution respectively,then oxymatrine was used for 48 h before changing to maintenance medium; ③Vero cells were attacked by HFRSV at dilution of 10-1 ～ 10-6 respectively,and meanwhile treated with oxymatrine for 48 h before changing to maintenance mcdium.Each dilution handled four porocytes,and four positive controls were set up at the same time.Indirect immunofluorescence assay (IFA) was performed to determine the inhibitory effect of oxymatrine in experimental group and positive control.In vivo studies,thirty 2-week-old hamsters,weighing about 30-40 g,were divided into experimental and control groups according to body weight,n =15.These aninals were inoculated intraperitoneally with HFRSV in 100TCID50(0.1 ml each); on days 4-13,0.1 ml of oxymatrine 1:100 were given to each hamster in experimental group daily by intraperitoneal injection,while the same amount of saline was given to the control ones.Lung tissue of hamsters was then dissected out to slice to be identified by immunofluorcscence stain.Results It was demonstrated that oxymatrine with the diluted fractions of 1:8 was safe in vitro.When the virus dilution of HFRSV was l0-4,compared with control groups,the differences were statistically significant in method 2 and 3 (z =-2.53,-2.53,all P ＜ 0.05),while no statistical significance in method 1 (z＝5.36,P＞ 0.05).When the virus dilution of HFRSV was 10-1 ～ 10-3,10-5,10-6,the differences were not statistically significant (z--0.00,-0.32,-0.19,4.21,4.21,all P ＞ 0.05).In vivo studies,compared with control group,the differences were statistically significant in experimental group (z =-3.85,P ＜ 0.05).Conclusion Oxymatrine significantly inhibites HFRSV.

OBJECTIVESulfur dioxide was considered to be toxic and detrimental to human health. However, this review highlights recent advances that suggest sulfur dioxide might be a novel endogenous gaseous signaling molecule involved in the regulation of cardiovascular functions.

DATA SOURCESThe data used in this review were mainly from the studies reported in Medline and PubMed published from 1986 to 2010.

STUDY SELECTIONOriginal articles and critical reviews selected were relevant to exogenous and endogenous sulfur dioxide.

RESULTSThe sulfur dioxide/aspartate amino transferase pathway is endogenously generated in the cardiovascular system, and sulfur dioxide shows broad bioactive effects, such as antihypertension, vasodilation, and amelioration of vascular remodeling. A disturbed sulfur dioxide/aspartate amino transferase pathway is known to be involved in the pathogenesis of many cardiovascular diseases, such as ischemia-reperfusion injury, monocrotaline-induced pulmonary hypertension, athrosclerosis, spontaneous hypertension and hypoxic pulmonary hypertension. Furthermore, in experimental studies the prognosis of these cardiovascular diseases can be improved by targeting endogenous sulfur dioxide.

CONCLUSIONThe findings suggest that sulfur dioxide is a novel endogenous gaseous signaling molecule involved in the regulation of cardiovascular functions.

OBJECTIVEJianyate Hao (JYTH) , a traditional Chinese medicine formula, which has been used effectively to treat depression in the past ten years. The purpose of this study was to explore the antidepressant effect of acute administration with JYTH and its possible mechanism.

METHODthe animals behavioral despair models of depression, the tail suspension and forced swimming tests, were used to explore the antidepressant effects of JYTH. In addition, the locomotor activity test was used to detect the change of locomotor activity. The monoamine oxidase activity in the mouse brain was also determined by using fluorospectrophotometry.

RESULTJYTH (17.5, 35, 70 g x kg(-1), ig) could decrease the duration of immobility in both tail suspension and forced swimming tests, and the effect of JYTH (35 g x kg(-1) ig) was resembling imipramine (10 mg x kg(-1), ip) in relieving depression. And the effective doses (17.5, 35, 70 g x kg(-1), ig) did not alter locomotion activity. Moreover, JYTH (35 g x kg(-1), ig) was found to inhibit monoamine oxidase activity in the mouse brain.

CONCLUSIONThese findings suggest that JYTH exerts antidepressant effect in animals behavioral despair tests and the underlying mechamism may involve the inhibition monoamine oxidase activity in the mouse brain.
