Objective To compare the treatment effect of laparoscopic appendectomy(LA) and open appendectomy (OA). Methods One hundred and forty-five cases of LA performed from May 2003 to May 2005, and 142 cases of OA performed from June 2001 to March 2003 were studied retrospectively. Results There was no difference in operative time between group LA and group OA. In the procedure of LA, some occult disease could be discovered and treated, while OA was not. The administration of analgesic, activity time, incidence of incision infection and hospital stay in group LA were better than those of OA group. While the cost of hospitalization in LA was higher than that of OA. Conclusion LA has significant advantages in treating appendicitis and it should be promoted.

Objective To study the anti-tumor effects of alcohol extraction of Coix stalk objects on H22 tumor-bearing mice. Methods The animal model of tumor bearing mice with H22 ascitic tumor cells was established. Eighty-four model mice were randomly and equally divided into Coix stalk extract groups 1-5 (10, 8, 6, 4 and 2 g/kg), model control group and cyclophosphamide group. Mice were treated orally with Coix stalk alcohol extraction solution (10, 8, 6, 4 and 2 g/kg), cyclophosphamide 0.02 g/kg and normal saline once a day for 8 days for Coix stalk extract group, cyclophosphamide group and model control group. The mouse activity, the size and the appearance of time of abdominal swelling, and changes of hair, feeding and drinking water quantity were observed in groups of mice. The solid tumor mass was measured in H22 tumor-bearing mice. The tumor inhibitory rate, liver index, spleen index and thymus index were calculated. Results The axillary tumor muster was found first in model control group with the fastest growth, reduced independent activity, decreased appetite and dim in hair color, followed by the Coix stalk extract group 1 and group 2. The last was Coix stalk extract group 5 and cyclophosphamide group. The solid tumor mass were (0.47±0.18), (0.37± 0.13), (0.34±0.10), (0.30±0.11) and (0.28±0.09) mg for Coix stalk alcohol extract groups 1-5, which were significantly lower than those of model control group (0.60 mg±0.21 mg, F=5.700,P<0.05). The tumor inhibition rates were 21.67%, 38.33%, 43.33%, 50.00%, 53.33%and 60.00%in Coix stalk extract groups 1-5 and cyclophosphamide group. The liver index, spleen index and thymus index were lower in cyclophosphamide group and Coix stalk alcohol extract groups than those of model control group (except for the spleen index of Coix stalk extract group 1). The liver index was lower in Coix stalk ethanol extract groups than that of cyclophosphamide group. There were no significant differences in the spleen index, thymus index between Coix stalk ethanol extract groups and cyclophosphamide group. Conclusion Coix stalk alcohol extract has inhibitory effects on the tumor and liver damage in H22 mice.

AIM:To explore the protective effect of ischemic preconditioning on myocardial capillary bed. METHODS: Anesthetized open-chest dogs in ischemic preconditioning (IP) group ( n =6) were subjected to 5 min ischemia and 5 min reperfusion for 4 times in left descending coronary artery (LDA) while the dogs in sham-operated (SO) group ( n =6) were observed for 40 min without any stimulating. Myocardial contrast echocardiography (MCE) was performed before the surgery, at the end of the first and the fourth ischemia and reperfusion period, respectively. Myocardial samples in ischemic area were obtained for capillaries ultrastructure examination and their quantitative analysis was conducted by corresponding imagine analyzing system, then compared within group and between control group. RESULTS: (1) Comparing fourth 5 min ischemia with first one, the percents of area defect in minimum (AD min%) by MCE decreased from 32.6%?5.7% to 21.8%?5.2%( P

Objective:To study the anti-inflammatory and analgesic effects of different solvent extracts of Folium Pyrrosiae. Meth-ods:Water extract and 75% alcohol extract of Folium Pyrrosiae were obtained. Mouse auricle swelling model induced by xylene was used to observe the anti-inflammation. The analgesic effect was tested by acetic acid writhing test and hot plate test. Results:The eth-anol extract of Folium Pyrrosiae could markedly inhibit the mouse auricle swelling induced by xylene (P<0. 01), and had the ability to inhibit the twisting induced by acetic acid in the mice (P <0. 05). The ethanol extract of Folium Pyrrosiae could increase the threshold of pain in the mice significantly after the 1-hour and 2-hour treatment (P<0. 05). The water extract of Folium Pyrrosiae could inhibit the mouse auricle swelling induced by xylene and the writhing reaction induced by acetic acid (P<0. 05). The water ex-tract of Folium Pyrrosiae could increase the threshold of pain in the mice significantly after the 1-hour treatment (P<0. 05). Conclu-sion:Folium Pyrrosiae has obvious analgesic and anti-inflammatory effects.

To establish a method for isolation, culture and identification of adipose-derived mesenchymal stem cells (ASCs) from the inbreed line miniature pig of Wuzhishan (ILMW).
Methods: A total of 100 g adipose tissues were obtained from subcutaneous tissues of neck in six-month old healthy ILMW (3 samples, male). ASCs from ILMW (ILMW-ASCs) were isolated from adipose tissues through 0.1% collagenase digestion. The cells at the 3rd, 5th, 8th, 13th passages were collected. Cell morphology, size, phenotype, cell cycle, and apoptosis were monitored. Cell differentiation was induced and cell proliferation curve was drawn.
Results: The ILMW-ASCs, fibroblast-like or whirlpool-like, began the adherence at 36 h and entered a logarithmic phase in the 5th day. Eighty percent of them were fused in the 7th day. The average diameter and volume of ILMW-ASCs were (17.00±0.54) µm and (2.58±0.24)×10-9 L, respectively. The expressions of CD29, CD44 and CD90 were positive, and there was no significant difference between the different passages (all P>0.05). The expressions of CD45, CD8a and HLA-DR were increased with the increase in passages after the 3th passage (all P<0.05). The adipogenic induction of ILMW-ASCs was observed by positive oil red O staining, and the osteogenic induction of ILMW-ASCs was determined by positive alizarin red staining. Apoptosis and senescence occurred in the 13 passage of ILMW-ASCs, and the proportion of S phase of cell cycle was lower than that in lower passages (all P<0.05).
Conclusion: ILMW-ASCs are one of the best choice for porcine ASCs, which might provide a source of candidate stem cells for therapy of large animal disease models and tissue or organ repairment.
