Objective To compare the outcomes of giant hepatic hemangioma undergoing enucleation and hepatectomy and to summarize our experience of surgical management of liver hemangioma.Methods A retrospective study was conducted in patients undergoing giant hepatic hemangioma resection (lager than 10 cm in size) in General Hospital of PLA,during 2006 through 2014.Patients were divided into two groups according to the types of operation.Results Of 145 patients with giant liver hemangioma,81 underwent enucleation and 64 had hepatectomy.The differences of tumor size (12.0 cm vs.15.5 cm,u =3.68,P ＜0.01),time of operation (210 min vs.280 min,u =3.89,P ＜ 0.01) and the ratio of inflow control (81.5％ vs.56.3％,x2 =10.91,P ＜ 0.01) of enucleation and hepatectomy was significant.The difference of intraoperative blood loss (500 ml vs.800 ml,u =1.85,P =0.07) and the postoperative morbidity (8.6％ vs.7.8％,x2=0.03,P =0.86) was not statistically significant.There was no inhospital mortality in both groups.Conclusions Both of enucleation and hepatectomy are effective operative approaches for giant liver hemangioma,patients with liver hemangioma should be prudently chosen for surgery,and the operation type should be individualized with the guidance of precision liver surgery.

OBJECTIVETo observe the effect of Bushen Huoxue Recipe (BSHXR, a Chinese medicine recipe for Shen reinforcing and blood circulation activating) on the levels of urinary albumin, interleukin-6 (IL-6), transforming growth factor-beta1 (TGF-beta1), and monocyte chemotactic protein-1 (MCP-1) in chronic nephritis patients of Shen-deficiency blood-stasis syndrome.

METHODSForty-five patients were blocking assigned randomly to two groups, fifteen patients in the control group and thirty in the treatment group. All orally took Monopril 10 mg, once daily. But BSHXR was given additionally to patients in the treatment group after decocting,one dose per day (taken in two times). The treatment course for both groups was eight weeks. Besides, a normal control group consisting of six healthy subjects from health examination of Shuguang Hospital was set up. The 24-h urinary albumin and contents of TGF-beta1, IL-6 and MCP-1 in urine of all subjects were observed.

RESULTSCompared with before treatment the 24-h urinary albumin was obviously reduced in the treatment group, showing significant difference (P<0.01). The urinary 24-h albumin decreased in the control group, with statistical significance (P<0.05). Statistical difference existed between the treatment group and the control group after treatment (P<0.01). Compared with before treatment, urinary levels of IL-6, TGF-beta1, and MCP-1 were all down-regulated in the treatment group and the control group after treatment (P<0.01), and the decreasing of IL-6 and TGF-beta1, levels was more significant in the treatment group statistically (P<0.05).

CONCLUSIONSBSHXR could attenuate the albuminuria in patients of chronic nephritis. Its mechanism might be possibly correlated with its down-regulation of IL-6, TGF-beta1, and MCP-1 levels.

OBJECTIVETo explore clinical efficacy of Yiguanjian Decoction (YD) combined Adefovir Dipivoxil Tablet (ADT) in treating HBeAg negative chronic viral hepatitis B (CVHB) active compensated liver cirrhosis (LC) patients.

METHODSTotally 68 HBeAg negative CVHB active compensated LC patients initially treated were assigned to the treatment group and the control group using random digit table, 34 in each group. Patients in the control group took ADT alone, 10 mg each time, once per day. Those in the treatment group additionally took YD, one dose per day. The therapeutic course for all was 48 weeks. Levels of alanine aminotransferase (ALT), aspartate aminotransferase (AST), total bilirubin (TBil) were detected once in every two weeks. Hepatitis B virus (HBV)-DNA and four items of serum liver fibrosis [procollagen type I (PCN), hyaluronidase (HA), procollagen III peptide (PCIII), laminin (LN)] were detected once per every 4 weeks. Abdominal ultrasound B was performed before and after treatment. The inner diameter of the portal vein and the size of spleen were recorded. The fibrosis degree of liver was evaluated using Fibroscan. Efficacy of Chinese medicine (CM) was evaluated between the two groups before and after treatment using CM syndrome integrals. Efficacy of Western medicine (WM) was also evaluated between the two groups using Child-Pugh grading. Results Compared with before treatment in the same group, ALT and AST levels restored to normal levels, HBV-DNA turned negative (HBV-DNA < or = 1 x 10(2)) in the two groups after 48-week treatment. Besides, levels of TBil, ALB, PCIV, HA, PCIII, and LN obviously decreased (P < 0.05, P < 0.01). Results of ultrasound B showed the inner diameter of the portal vein and the size of spleen decreased. Fibroscan results showed that the elasticity value of the liver obviously decreased (P < 0.05). Besides, post-treatment levels of PCIV, HA, PCEJ, and LN, and the elasticity value of the liver decreased more obviously in the treatment group than in the control group (P < 0.01). There was no statistical difference in post-treatment levels of ALT, AST, TBil, ALB, inner diameter of the portal vein, or the size of spleen between the two groups (P > 0.05). Compared with before treatment in the same group, scores of Chinese medical syndrome and Child-Pugh scores decreased in the two groups after treatment (P < 0.05, P < 0.01). Besides, scores of Chinese medical syndrome decreased more obviously in the treatment group than in the control group (P < 0.05). The effective rate was 8824% (30/34) in the treatment group, higher than that of the control group [67.65% (23/34)] with statistical difference (P <0.05). Conclusion Combined treatment of YD and ADT could significantly improve symptoms of CM and fibrosis degree of liver of HBeAg negative CVHB active compensated LC patients.

Natto extract could prevent effectively the fatty degeneration of liver cells observed by pathological sections. Conclution: Natto extract can efficiently prevent the formation of experimental hyperlipidemia.

Objective To investigate the effect of selenium on proliferation and apoptosis of chondrocytes of articular cartilage cultured in vitro in Kaschin-Beck disease(KBD) patients and normal person, to explore the role of selenium in control of KBD, and to provide evidence for selenium's effect on the growth of normal cartilage cells. Methods The articular cartilage samples of grade Ⅱ and Ⅲ KBD patients were selected according to the national "Clinical Diagnosis of KBD" (GB 16003-1995). Chondrocytes of 5 KBD and 5 non-endemic normal accidentswere separated and cultured in vitro. KBD group and control group were given different doses of selenium (0,0.0125,0.0250,0.0500,0.1000,0.2500,0.5000,1.0000 mg/L, respectively). Methyl thiazolyl tetrazolium (MTT),flow cytometric analysis, and immunocytochemical staining were used to observe the effect of selenium on cell growth and apoptosis in KBD and normal persons. Results MTT results showed that the cell proliferation rate in each dosage group of the control group at the 6th day(0.086 ± 0.025,0.077 ± 0.012,0.073 ± 0.027,0.071 ± 0.017,0.058 ± 0.028,0.052 ± 0.028 and 0.046 ± 0.037) was significantly lower than that of 0 mg/L group(0.138 ± 0.026,all P ＜ 0.05);the average cell proliferation rate was negative( - 0.001 ± 0.001, - 0.003 ± 0.000, - 0.003 ± 0.001and - 0.004 ± 0.001 ) in 0.1000 - 1.0000 mg/L dose group, which was significantly lower than that of the 0 mg/L group(0.025 ± 0.003, all P ＜ 0.05);compared with 0 mg/L group(0. 115 ± 0.011), the KBD 0.2500 mg/L dose group promoted cell proliferation(0.128 ± 0.037, P ＜ 0.05), the KBD 1.0000 mg/L dose group inhibited cell growth (0.071 ± 0.019, P ＜ 0.05). The apoptotic rate of 0.0500 - 1.0000 mg/L dose control group [ (18.88 ± 0.02)%,(17.58 ± 0.01)%, (17.09 ± 0.04)%, (56.00 ± 0.02)%, (57.85 ± 0.03)% ] were higher than that of the 0 mg/L group[(13.51 ± 0.01)%, all P ＜ 0.05];compared with 0 mg/L group[(25.84 ± 0.02)%], the apoptotic rate in KBD 0.0250 - 0.2500 mg/L dose group [ ( 13.69 ± 0.02) %, ( 15.96 ± 0.03 ) %, ( 16.68 ± 0.03 ) %, ( 16.67 ± 0.02) % ]were lower, and the apoptotic rate in 0.5000, 1.0000 mg/L dose group [ (59.58 ± 0.03)%, (73.48 ± 0.04)% ] were significantly higher(all P ＜ 0.05). The Fas expression in KBD 0.0500 - 0.2500 mg/L dose groups[ (41.2 ± 1.5)%,(40.3 ± 2.0)%, (50.2 ± 2.5)%] were lower than those of the same dose control group with selenium intervention [(52.4 ± 1.0)%, (67.2 ± 4.0)%, (75.1 ± 5.0)%, all P ＜ 0.05], the caspase-3 expression in KBD 0.0500,0.1000 mg/L dose groups[ (40.8 ± 1.1 )%, (45.1 ± 2.1 )%] were lower than those of the same dose control group with selenium intervention[ (68.0 ± 3.0)%, (70.6 ± 3.5)%, all P ＜ 0.05 ]. Conclusions Appropriate dose of selenium supplementation (0.1000 - 0.2500 mg/L) could promote the growth of KBD chondrocyte, decrease cell apoptosis,but have a damage when the dose of selenium ＞ 0.5000 mg/L;doses of selenium that could promote the growth of KBD chondrocyte does not mean to promote the growth of normal cartilage cells in vivo.

OBJECTIVETo investigate the effect and acting mechanism of Bushen Huoxue Recipe (BHR) on the state of extracellular matrix in glomerulosclerosis (GS) rats model.

METHODSGS rat model was established by unilateral nephrectomy and adriamycin injection. Model rats were randomly divided into 4 groups: the normal control group, the model group, the test group treated by BHR, and the positive control group treated with fosinopril sodium, with 11 rats in each group. The 24 h urinary protein and renal function of rats were observed, the contents of matrix metalloproteinase 1 (MMP-1), tissue inhibitor of metalloproteinase 1 (TIMP-1) in renal tissue and transforming growth factor-beta1 (TGF-beta1) in blood plasma, and renal tissue were detected.

RESULTSCompared with those in the normal control group, 24 h urinary protein was increased and renal function was deprived in the model group; TIMP-1 expression increased, MMP1 expression decreased in renal tissue of rats in the model group, showing statistical difference between groups (P < 0.05). As compared with the model group, the abnormal changes of TIMP-1 and MMP1 expressions were ameliorated in the two groups treated either by BHR or fosinopril (P < 0.05). The content of TGF-beta1 in the model group, either in blood or in renal tissue, was significantly higher than those in the normal control group respectively (P < 0.01), showing no significant change after BHR treatment.

CONCLUSIONThe protective effect of BHR on renal function in rats with GS is possibly by way of influencing expressions of TGF-beta1, TIMP-1 and MMP1 to regulate the state of extracellular matrix and lessen the matrix aggregation.
