Objective To investigate the application value of intraoperative ultrasound (IOUS) in living donor liver transplantation(LDLT). Methods In LDLT, IOUS techniques (gray scale ultrasound and color Doppler flow imaging) were adopted in 26 donors and recipients for parenchymal and vascular examinations. The abnormal sonograms were observed, and the anatomic findings of hepatic veins were recorded. All the reanastomosed blood vessels were examined by gray scale ultrasound and color Doppler flow imaging before the operations were completed. Results A hepatic parenchymatous tumor was revealed by IOUS in one donor. Besides, middle hepatic veins in 13 donors and secondary hepatic veins with diameter﹥0.5 cm in 5 donors were confirmed by IOUS. Furthermore, one operation procedure was changed and one hepatic artery stenosis was established according to IOUS findings. Conclusion IOUS is a very useful means in evaluation of parenchymal and vascular conditions of donors and recipients in LDLT, which helps to select the best cross section and provides evidence for the change of surgical procedures.

Chinese Journal of Primary Medicine and Pharmacy 2008;15(5):718-719
Objective To understand the influence of operation to quality of life by evaluating the QoL of the patients with rectal cancer, before and after the Miles' operation. Methods To select 57 patients received Miles operation. To evaluate the quality of life of the 57 sample patients that before Miles' operation and the first, the sixth, the twelfth month after the operation by using the QoL evaluation sheet.

BACKGROUND:Adipose-derived stem cel s are totipotent stem cel s in the adipose tissue, and have the function of self-renewal and multi-directional differentiation. Human adipose-derived stem cel s are ideal seed cel s with stable genetic milieu and few rejections.
OBJECTIVE:To extract human adipose-derived stem cel s from human omental adipose tissue and to identify the cel s by adipogenic and osteogenic induction.
METHODS:Omental adipose tissues were col ected from surgical patients to isolate and culture adipose-derived stem cel s using type I col agenase digestion, filtration and centrifugation. Cel growth was observed and proliferative curve of human adipose-derived stem cel s were drawn by cel counting method to calculate the doubling time at logarithmic growth phase. After adipogenic and osteogenic induction, induced cel s were identified using oil red O and alizarin red staining, respectively.
RESULTS AND CONCLUSION:Human adipose-derived stem cel s were successful y isolated from the omentum tissues of surgical patients. Adherent cel s were fusiform-shaped and like fibroblasts. The growth curve of passage 3 cel s was in S shape, and the doubling time was 45.90 hours. After adipogenic and osteogenic induction for 2 and 3 hours, respectively, oil red O staining showed unequal-sized orange fat droplets, and alizarin red staining showed typical calcified nodules that were in orange. These findings indicate that adipose-derived stem cel s have the adipogenic and osteogenic capacity.

Objective To explore whether 5 to -7-day of folic acid supplementation prior to pemetrexed therapy is needed. Methods We retrospectively evaluate the outcomes of non-small cell lung cancer patients received less than the advised folic acid premedication. Seventy patients with Ⅲ-Ⅳ NSCLC were randomly divided into two groups: patients who initiated vitamin supplementation on 7 days before the first dose of pemetrexed (group A) and patients who initiated vitamin supplementation on the day of the first dose of pemetrexed (group B). Results In group A and group B, CR 0 and 0, PR 10 and 8, the response rates of 28.6% and 22.9% were observed, respectively. There was no statistically significant differences between these two groups. No significant differences were observed in the incidence of hematologic and non-hematologic toxicities. Conclusions The initiation of pemetrexed-based chemotherapy does not need to accommodate a vitamin supplementation schedule.

BACKGROUND:It is unclear whether serial cel passage in vitro influences the differentiation of bone marrow mesenchymal stem cel s into neural stem cel s.
OBJECTIVE:To investigate the effect of cel passage on the differentiation of bone marrow mesenchymal stem cel s into neural stem cel s.
METHODS:Rat bone marrow mesenchymal stem cel s were isolated and cultured by the whole bone marrow adherence method. Bone marrow mesenchymal stem cel s at passages 3, 6, 9, 12 were incubated in serum-free medium. After culture for 7 and 14 days, cel biological characterization was observed and differenitaiton ability into neural stem cel s was observed by detecting Nestin expression in cel s using flow cytometry. Then, the cel s were further induced to differentiate and cel multipotential differentiation capacity was detected by measurement of nerve enolase and glial acidic protein expression.
RESULTS AND CONCLUSION:Under induction, bone marrow mesenchymal stem cel s at different passages were al differentiated into Nestin-positive neural stem cel s. However, there was a significant difference in differentiation proportion of cel s at different passages (P<0.05). Strongest differentiation ability was found in the passage 6 cel s, with the Nestin expression up to (93.7±2.3)%at 7 days of induction and (96.2±1.8)%at 14 days of induction. The proportion of differentiated cel s at passages 6 and 9 was signfi cantly higher than that at passages 3 and 12. Moreover, adherent cel s were positive for nerve enolase and glial acidic protein. Al these findings indicate that the differentiation of bone marrow mesenchymal stem cel s into neural stem cel s is correlated with cel passage. Cel s at lower or higher passages are both detrimental to cel differentiation.
