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.

OBJECTIVETo explore the effect of combination of Epimedii Folium and Ligustri Lucidi Fructus on osteoporosis rats induced by retinoic acid.
METHODSixty three-month-old male Wistar rats were randomly divided into the normal control group, the model group, the Epimedii Folium group, the Ligustri Lucidi Fructus group, the combination group of Epimedii Folium and Ligustri Lucidi Fructus and the raloxifene group. The osteoporosis model was established through oral administration with retinoic acid for two weeks. Meanwhile, all of treatment groups were administered with corresponding drugs for three weeks. The contents of serum calcium (Ca), phosphorus (P), alkaline phosphatase (AKP) and tartrate-resistant acid phosphatase (StrACP) were detected, and the pathomorphological changes of femurs were observed.
RESULTThe model control group showed much lower contents of serum Ca and P than the normal control group, but with significantly higher AKP and StrACP activity than the normal control group. The femoral head area showed reduced, narrow and sparse trabecular bones, with typical osteoporosis-like changes. Compared with the model control group, all of treated groups showed significant increase in Ca and P contents in serum, and down-regulate AKP and StrACP levels, while trabecular bones became more and wider, and densely interweaved as a reticular formation. Among them, the combination group showed the most significant effect.
CONCLUSIONEpimedii Folium and Ligustri Lucidi Fructus could effectively correct the abnormal bone metabolism and improve pathological conditions of bone tissues, so as to show the anti-osteoporosis effect. The combined application of the two drugs showed a better efficacy.

OBJECTIVEThis study aims to examine the expression of nuclear factor κB (NF-κB)/B cell lymphoma-2 (Bcl-2) signal pathway and glycogen synthase kinase 3β (GSK-3β) in oral squamous cell carcinoma (OSCC) and provide references for the early diagnosis and prognosis evaluation of OSCC.
METHODSA total of 55 cases of OSCC and 10 cases of paracan- cerous mucosa were examined in this study. Their expressions of GSK-3β, NF-κB and Bcl-2 were detected using the SP me- thod immunohistochemistry. The correlation between their expression in OSCC and the clinical and pathological peculiarity of OSCC was analyzed.
RESULTSThe positive expression of GSK-3β, NF-κB, and Bcl-2 in OSCC were significantly higher than that in paracancerous mucosa (P < 0.01). The expression of GSK-3β, NF-κB, and Bcl-2 had no obvious relationship with patient's age, sex, and clinical stages of the disease (P > 0.05). The expression of Bcl-2 was significantly correlated with the degree of tumor differentiation (P < 0.05), whereas the expression of GSK-3β and NF-κB in OSCC had no obvious relation- ship with the degree of tumor differentiation (P > 0.05). Strong positive correlations were observed among the expressions of GSK-3β, NF-κB, and Bcl-2 (P < 0.05).
CONCLUSIONThe positive expression of GSK-3β, NF-κB, and Bcl-2 in OSCC are sig- nificantly higher than that in paracancerous mucosa. Detecting GSK-3β, NF-κB, and Bcl-2 in OSCC may have implications in the early diagnosis and prognosis evaluation of OSCC.
