Objective To explore the causes of biliary complications related with liver donor fol- lowing liver transplantation.Methods Ninty-nine patients with improved liver donor treatment during liver transplantation from May 2005 to April 2006 were followed up and the clinical data were ana- lyzed.At the same time,the rate of biliary complications was compared with that occurring on 43 pa- tients with unimproved liver donor treatment.Results Only 4 in 99 patients with improved liver donor treatment had biliary leakage with the rate of biliary complications being 4% in comparison with 11% in those with unimproved liver donor treatment.Conclusion The improvement of liver donor treat- ment,including shortening heat-ischemia time,completely washing bile duct and remaining the whole blood supply of bile duct,can decline the occurrence of biliary complications.

AIM: To evaluate the anatomic and visual outcomes of 25-gauge vitrectomies combined with air tamponade for the treatment of idiopathic macular hole (IMH).METHODS: Thirty eyes of 27 patients with IMH were included in this prospective interventional study.All patients underwent 25-gauge pars plana vitrectomy (PPV) combined with phacoemulsification and air tamponade.Best corrected visual acuity (BCVA, logMAR), perimetry and multifocal electroretinography (mfERG) were conducted before and after the operation.Anatomical changes were evaluated with optical coherence tomography (OCT).RESULTS: The macular holes closed successfully in 28 eyes after the primary vitrectomy.The mean BCVA improved from 0.72±0.22 logMAR preoperatively to 0.29±0.18 logMAR postoperatively (P<0.001).In the visual field of central 10°, the average mean deviation (MD) decreased from-3.59±1.83 dB preoperatively to-2.51±1.36 dB postoperatively (P<0.001) and the average pattern standard deviation (PSD) decreased from 1.86±0.68 dB preoperatively to 1.33±0.32 dB postoperatively (P=0.001).The retinal response densities of mfERG in the foveal and perifoveal area increased significantly, and implicit times of rings 4-6 prolonged significantly (P<0.05).The symptom duration and baseline N1 amplitude densities at ring 1 had a significant impact on postoperative BCVA (P<0.001, P=0.001, respectively).CONCLUSION: The 25-gauge PPV and air tamponade with 1 day prone positioning produce favorable anatomic and functional outcomes.

Objective To observe the effects of standardized three stage rehabilitation treatment on the neu- rological deficit scores (NDS) and ADL performance of ischemic stroke patients.Methods A total of 164 ischemic stroke patients were recruited and randomly divided into a rehabilitation group and a control group.The neurological function and ADL performance of the patients were assessed by using NDS and Modified Barthcl Index (MBI) at the admission,at the end of 1st,3rd and 6th months post stroke.Results No significant differences were found be- tween the rehabilitative and the control groups with regard to NDS and MBI at admission.The NDS demonstrated a decreasing tendency,while the MBI score an increasing tendency in both groups.In the control group,significant difference of NDS was found between admission and the end of 1st month as well as between the end of the 1 st and the 3rd months.In rehabilitation group,significant difference was revealed between all the time points with regard to NDS and MBI scores.At the end of the 1st,3rd and 6th months,the MBI scores of the rehabilitation group were signifi- cantly higher than those of the control group,indicating that the ADL performance of those treated with standardized three-stage rehabilitation protocol was improved quicker than those without the protocol.Conclusion Standardized three-stage rehabilitation treatment could improve the neurological function and ADL performance of the ischemic stroke patients.

The clinical experiences and proven cases of distinguished doctor of TCM, professor WU Xu, on acupuncture for acute upper abdominal pain is introduced. Professor WU's manipulation characteristics of acupuncture for acute upper abdominal pain, including acute cholecystitis, kidney stone, acute stomach pain, are one-hand shape but both hands in nature, moving like Tai Chi, force on the tip of needle, movement of qi mainly. The main technique posture is one-hand holding needle with middle finger for pressing, the needle is hold by thumb and index finger, and is assisted by middle finger. The special acupuncture experience of emergency is treatment according to syndrome differentiation, combination of acupuncture and moxibustion, selecting acupoint based on experience, blood-letting acupuncture therapy and so on.

AIMTo investigate the protective effects of shark hepatic stimulator substance (sHSS) against acute hepatic injury induced by acetaminophen (AAP) in mice.

METHODSAcute hepatic injury model of Balb/c mice was induced by a single intraperitoneal injection of AAP (200 mg.kg-1, i.p.). Serum ALT and AST activities were analyzed. The changes of microstructure and ultrastructure of hepatocyte were observed under optical and electronic microscope. The hepatocyte apoptosis was analyzed by flow cytometer and the expression level of Fas mRNA was determined by RT-PCR.

RESULTSThe activities of serum ALT and AST were significantly decreased and both necrosis and inflammatory infiltration were improved in the mice treated with sHSS 3.0 and 1.5 mg.kg-1. sHSS (3.0 mg.kg-1) prevented the ultrastructural changes of hepatocytes caused by AAP, decreased the percentage of apoptotic cells, and downregulated the expression level of Fas mRNA.

CONCLUSIONsHSS protected hepatocytes from AAP-induced injury, which might be associated with its protection of the mitochondria and inhibition of apoptosis and expression of Fas mRNA in hepatocytes.

OBJECTIVETo identify possible reasons of rotational mismatch between tibial component and femoral component in total knee arthroplasty and choose a right reference axis for placing the components in the operation and to decrease the complications.

METHODSForty normal Chinese knees were studied. There were 20 men and 20 women, and average age was 34 years (range, 18 - 42 years). The images of cross sections of the distal femur were obtained by spiral CT scanning (0.5 mm thickness). Scan direction was aligned to be in the plane perpendicular to the mechanical axis of the tibia. On the images of the distal femur and the proximal tibia, three baselines for the anteroposterior axis of the femoral component were drawn based on the clinical epicondylar axis and the surgical epicondylar axis and 3 degrees lateral rotated to the posterior condylar surfaces of the femur separately, and a baseline for the anteroposterior axis of the tibial component was drawn based on the medial 1/3 of the tibial tuberosity. The rotational mismatch angles were measured between each component by using the Autocad software.

RESULTSThe mean rotational mismatch angle between tibial component and femoral component is 2.94 degrees for the clinical epicondylar axis, 6.50 degrees for the surgical epicondylar axis and 6.83 degrees for 3 degrees lateral rotation of the femoral component referenced to the posterior condylar axis separately.

CONCLUSIONSLandmarks of each bone were the intrinsic cause of the rotational mismatch in total knee arthroplasty. The clinical epicondylar axis can be chosen for the ideal reference to rotational alignment of the femoral component because of its minimal rotational mismatch between each component.

?AlM: To investigate repeatability and accuracy of a latest Keratograph for evaluating the tear film stability and to compare its measurements with that of traditional examination methods.
?METHODS: The results of noninvasive tear film break-up time ( Nl-BUT ) including the first tear film break-up time ( BUT-f ) and the average tear film break-up time ( BUT - ave ) were measured by Keratograph. The repeatability of the measurements was evaluated by coefficient of variation ( CV ) and intraclass correlation coefficient ( lCC) . Wilcoxon Signed-Rank test was used to compare Nl-BUT with fluorescein tear film break-up time ( FBUT) to confirm the correlation between Nl-BUT and FBUT, Schirmer l test values. Bland-Altman analysis was used to evaluate consistency.
?RESULTS: The study recruited 48 subjects ( 48 eyes ) (mean age 38. 7±15. 2 years). The CV and lCC of BUT-f were respectively 12. 6% and 0. 95, those of BUT-ave were 9. 8% and 0. 96. The value of BUT-f was lower than that of FBUT. The difference had statistical significance ( 6. 16±2. 46s vs 7. 46±1. 92s, P<0. 01). There was significant positive correlation between Nl-BUT and FBUT, Schirmer l test values ( P< 0. 01 ). The scope of 95% limits of agreement (LoA) was 4. 46s in BUT-f and FBUT, while the scope of LoA was 3. 64s in BUT-ave and FBUT.
?CONCLUSlON: Keratograph can provide Nl-BUT data that has a better repeatability and reliability, which has great application prospects in diagnosis and treatment of dry eye and refractive corneal surgery.

To establish a fingerprint spectrum for Atractylodis Macrocephalae Rhizoma stir-fried with wheat bran based on UFLC/Q-TOF-MS, and make a principal component analysis (PCA) with Markview software, in order to compare the changes of components between raw and processed Atractylodis Macrocephalae Rhizoma with raw wheat bran as the blank. The results showed that the changed in components raw Atractylodis Macrocephalae Rhizoma and Atractylodis Macrocephalae Rhizoma stir-fried with wheat bran were apparently observed by PCA. Six compounds were identified to have significant changes in mass fraction before and after being stir-fried, namely atractylenolide-I, atractylenolide-II, atractylenolide-III, atractylentrid, atractylon and an unknown compound. Among them, atractylenolide-I and atractylenolide-II generated from dehydration and dehydrogenation of atractylenolide-III may be the material base of Atractylodis Macrocephalae Rhizoma stir-fried with wheat bran for strengthening spleen.

Endothelin (ET) is a peptide released by vascular endothelial cells. Except for the potent vasoconstrictor function it plays an important physiological role in tissue differentiation and development, cell proliferation and hormone production. Investigation of the role of ET axis in a variety of tumors such as prostatic, cervical, breast carcinoma has provided evidences of its importance in cancer, recently. Data suggest that multiple functions of the ET axis have associations with mitogenesis, apoptosis inhibition, angiogenesis, and activation of proto-oncogene. The ET axis relates to invasiveness, osteoblast function, and metastatic cancer pain in advanced prostate cancer.
