The staining of F-actin in the ischemia reperfusion group was decreased significantly （P.05） compared with the normal control group. There was a marked loss of canalicular microvilli and distension of canalicular lumen in the ischemia reperfusion group. The staining of F-actin in the LA group was significantly increased than those in the I/R group （P.05）. Conclusions: Ischemia reperfusion induces an disruption of bile canalicular F-actin microfilaments and a loss of microvilli. Alpha-lipoic acid can protect bile canalicular F-actin microfilaments against IRI.

肝脏I/R可造成胆小管F-actin微丝破坏、微绒毛丧失，导致胆小管收缩减弱，胆汁排泄功能受损，这可能是大鼠肝脏I/ R后缺血型胆道病变发生的主要机制；α-硫辛酸通过清除氧自由基，降低脂质过氧化反应，调节细胞内氧化剂-抗氧化剂的含量，保护胆小管F-actin微丝结构免遭缺血再灌注损伤破坏，进而预防和治疗缺血型胆道病变。

Raman spectra of boron carbonitride nanotubes made by thermal decomposition under different temperatures and with different catalysts were analysized. The intensity ratio of D to G band, I D/I G, increases and then decreases with the increase of the temperature.

引 言 理论计算和实验研究都表明硼碳氮纳米管不但具有比碳纳米管更优异的机械、电学性能和更高的抗氧化能力[1，2 ] ，而且BCN纳米管的机械和电学性能不受其直径的影响，只与其组成有关[3 ] 。

Morphologic features ranged from single straight or branching tubules to complex cavitary networks, usually overlying areas of pigment epithelial alteration or subretinal fibrosis.

形态特征既有单个直形管、分支管、也有具有复杂空腔的管状结构，通常覆盖于发生改变的色素上皮或视网膜下纤维化区域。

Cases were undergone choledocholithotomy with T-tube drainage , 39 cases cholangiojejunostomy with T-tube drainage , 28 cases lobectomy of liver, 16 cases plastic repair of hepatic portle duct with cholangiojejunostomy.

Results 114 cases were follow-up surveyed from 6 months to 10 years, After operation,the superior rate and residual stone rate were respectively: it was 67.57%、54.05% in the group of choledocholithotomy with T-tube drainage ,78.38%、32.43% in cholangiojejunostomy with T-tube drainage , 96.15%、7.69% in lobectomy of liver, 85.71%、14.29% in plastic repair of hepatic portle duct with cholangiojejunostomy. The total superior rate was 79.82% and total residual stone rate was 31.58%.

To prevent cholelith in residual gallbladder, it is important to choose the proper timing and mode of cholecystectomy, to anatomize cystic duct, common hepatic duct, common duct clearly and cut cystic duct 0.3~0.5cm apart from common duct.

合理掌握胆囊切除术的手术时机、和术式，在术中解剖清楚胆囊管、肝总管、胆总管三管关系，然后距胆总管0.3~0.5cm切断结扎胆囊管，是预防残余胆囊结石的关键。

The split between the two groups can hardly be papered over.

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
