Objective To explore the best time point for the ipsilateral hepatocellular apoptosis and the contralateraI hepatic hypertrophy after selective portal vein embolization(SPVE)in rabbit.Methods In a randomized study design,forty rabbits were divided into 5 groups with 8 rabbits per-group,including one as the control and the other 4 were treated with SPVE during open surgery.The rabbits were killed postoperatively,in 3,7,14,21 days respectively after the embolization.The hepatic lobes volume,the ipsilateral hepatocellular necrosis rates and apoptosis index,and liver functions were determined as well. Results In the treatment groups,the average amount of the right liver volumes decreased from 46.4 cm~3 preoperatively to 46.0,44.4,42.0,39.7 cm~3 in groups of 3,7,14,21 days postoperatively;meanwhile,the left liver volumes increased from 54.0 cm~3 preoperatively to 54.5,56.3,61.7,63.9 cm~3 respectively during 3, 7,14,21 days after the procedures.The rates of future remaining live volumes(FRLV)increased from 53.8% preoperatively to 54.2%,55.9%,59.0%,61.0% at 3,7,14,21 days postoperatively.The apoptosis indexes of hepatocells from group A to E were 8.1%,12.2%,19.4%,20.1%,14.2% respectively.Conclusions SPVE leads to atrophy of the ipsilateral hepatic lobe and hypertrophy of contralateral lobe,indicating that hepatocytes undergone apoptosis,rather than necrosis.The time point is 7 to 14 days.

Objective To explore the clinicalpathological characteristics of Lynch syndrome associated ovarian cancer.Methods Totally 260 cases ovarian cancer patients were admitted to Tianjin Medical University General Hospital during Jan.2004 and Jan.2011,among which 10 patients( LS group) belonged to Lynch syndrome associated ovarian cancer according to Amsterdam Ⅱ criteria.One hundred ovarian cancer patients without any family cancer history were enrolled randomizely as control group (sporadic group).Results Lynch syndrome associated ovarian cancer accounted for 3.8％ ( 10/260),the incidence rate of ovarian cancer for female family members of Lynch syndrome was 8.7％ ( 10/115 ).Mean age at time of diagnosis in LS group was (46 ±7) years,significantly earlier than that in sporadic group [ (56 ±11 ) years,P ＜ 0.05 ].There was no statistical difference between two groups in histological type or International Federation of Gynecology and Obstetrics ( FIGO ) stage ( P ＞ 0.05 ).Most of the tissue differentiation in LS group were well or moderate differentiated,there was statistical difference between the two groups(9/10 vs.55％,P ＜0.05).The 3-year and 5-year survival rate in LS group were 87.5％ and 52.5％respectively,compared with 55.4％and 22.7％ in sporadic group(all P＜0.05).Conclusion Compared with sporadic ovarian cancer,Lynch syndrome associated ovarian cancer is more likely present as the clinicalpathological characteristics of early age of onset,serous adenocarcinoma,lower grade and better prognosis.

OBJECTIVETo investigate the effect of Xianxiong decoction on the mice with acute lung injury induced by lipopolysaccharide.

METHODEighty female ICR mice were randomly divided into 8 groups: model group, Xianxiong decoction group, Daxianxiong decoction group, Xianxiong decoction group without Kansui Radix group, Xianxiong decoction group without Glycyrrhizae Radix et Rhizoma group, Glycyrrhizae Radix et Rhizoma and Kansui Radix group, normal group and control group. Animals of each group, except normal group, were undertaken intraperitoneal injection and intranasal inhalation of lipopolysaccharide (LPS) on day 1, 2, 3 to establish acute lung injury (ALI) model. 30 min after modeling, 0.2 mL corresponding drugs were administrated to each mice, dexam ethasone and normal saline were given to the mice of control group and normal group respectively. White blood cell in blood, neutrophil percentage of blood and bronchoalveolar lavage fluid (BALF) supernatant, the ratio of wet and dry lung tissue ( W/D), histopathological changes of lung tissue were estimated. Sixty ICR mice were randomly divided into normal, model, control, high, middle and low dose Xianxiong decoction groups and were modeled in the same way. ELISA was applied to detect the level of NF-kappaB, TNF-alpha and IL-6 in BALF, PCR for NF-kappaB and TNF-alpha mRNA in lung tissue, and Western blot for NF-kappaB and TNF-alpha. Half of 20 ICR mice were administrated with Xianxiong decoction of its maximum tolerant normal saline.

RESULTCompared with model group, the number of WBC in blood of Xianxiong decoction group mice decreased (P < 0.01), percentage of neutrophils in both blood and BALF decreased as well (P < 0.01, P < 0.05); it also significantly reduced the ratio of W/D (P < 0.01); and found the alveolar wall, the number of inflammatory cells infiltrating improved, compared with model group. Xianxiong decoction reduced the level of NF-kappaB, TNF-alpha and IL-6 in BALF (P < 0.01, P < 0.01, P < 0.05); its high and low dose groups only found TNF-alpha level declined. Five mice died 24 h after administration of Xianxiong decoction which indicated its toxicity when other influential factors were considered.

CONCLUSIONXianxiong decoction is effective on the ALI mice induced by LPS, but it is of toxicity at 3 g x mL(-1).

To optimize indices of molecular identification for authentication of Ginseng Radix et Rhizoma and Panacis Quinquefolii Radix, four indices, including sequence similarity, specific positions, genetic distance and phylogenetic tree, were compared based on trnL-trnF sequences. Total DNA was extracted from Ginseng Radix et Rhizoma and Panacis Quinquefolii Radix, and trL-trnF sequences were amplified and sequenced. Sequence similarity was calculated by BLAST analysis. Specific positions were compared by DNAman software. Genetic distance and phylogenetic tree were analyzed by Mega software. The results showed that the inter-specific and intra-specific similarity of P. ginseng and P. quinquefolius respectively was 100% and 99. 6%. There were four specific positions at G153A, T463A, C732G and T818C. The inter-specific genetic distance (0) of trL-trnF sequences was lower than intra-specific genetic distance (0. 004). P. ginseng can be distinguished from P. quinquefolius based on the phylogenetic tree. It is concluded that Ginseng Radix et Rhizoma and Panacis Quinquefolii Radix can be authenticated by identification indices of sequence similarity, specific positions, genetic distance and phylogenetic tree. Index of specific positions based on trnL-trnF sequences is the most efficient index to authenticate Ginseng Radix et Rhizoma and Panacis Quinquefolii Radix.

OBJECTIVETo discuss the effect of Taohong Siwu Decoction (TSD) in regulating functions of endothelial cells and treating arteriosclerosis obliterans (ASO).

METHODSThe ASO model was prepared by using high-fat diet plus intimal injury. They were randomly divided into the model group (n = 10), the normal control group (n = 9), the low dose TSD group (group A, n = 12), the middle dose TSD group (group B, n = 10), and the high dose TSD group (group C, n = 9). Eight weeks after modeling, the limb blood perfusion was observed using laser Doppler flowmetry. The arterial morphology was observed using light microscope and transmission electron microscope. The number of circulating endothelial cells (CECs) was determined using Percoll density gradient centrifugation method. Serum levels of TNF-alpha, IL-1, ET-1, and NO were detected using double antibody sandwich assay of enzyme linked immunosorbent assay (ELISA).

RESULTSThe ASO rat model was successfully established. Blood lipids levels significantly increased, the blood perfusion of left hind limbs significantly decreased, the number of CECs in the peripheral blood significantly increased, the arterial lumen was irregularly narrowed, the ultra-structure of vessel walls was damaged, serum levels of TNF-alpha, IL-1, and ET-1 significantly increased, and the serum level of NO significantly decreased in the model group, showing statistical difference when compared with the normal control group (P < 0.01). Compared with the model group, significant improvement in the aforesaid indices was shown in group B and C (P < 0.05, P < 0.01).

CONCLUSIONSThe injury and abnormal functions of endothelial cells is an important pathological process of ASO. As an effective recipe for treating ASO, TSD could protect vascular endothelial cells and improve the secretion function of vascular endothelial cells.
