BACKGROUND: The low survival rate of neuron cells is one of the main mechanisms of stem cell allograft, which might lead to the failure of allograft. Nuclear factor-KB (NF-kB) is one of main transcription factors for cell signaling transduction and participates in call proliferation and differentiation.OBJECTIVE: To study the differentiation of muscle-derived stem cells (MDSCs) into neuron-like cells induced by ciliary neurotrophic factor (CNTF) and Compound Salvia Miltiorrhiza Injection in vitro, and the expression of NF- kB.DESIGN, TIME AND SETTING: The experiment at cell molecular level was performed at the Oral Science Laboratory of the Second Affiliated Hospital of Liaoning Medical College from March to May 2008.MATERIALS: A total of 10 Sprague Dawley neonatal rats aged 7 days were supplied by Experimental Animal Center, Liaoning Medical University. CNTF (Sigma, USA) and Compound Salvia Miltiorrhiza Injection (Chiatai Qingchunbao Pharmacantical Co.,Ltd., China) were used in this study.METHODS: Rat MDSCs were harvested in vitro, pudfied by differential adherence and enzyme digestion, and incubated in 6-well plate. Samples in the induction group were incubated in DMEM containing CNTF for 24 hours. The medium was changed.Subsequently, samples were dnsed three times, and then incubated in serum-free DMEM supplemented with Compound Salvia Miltiorrhiza Injection for 5 hours. Samples in the control group were treated with serum-free DMEM.MAIN OUTCOME MEASURES: Neurofilament protein and NF-KB inhibitor protein expression were detected using reverse transcription-polymerase chain reaction (RT-PCR) and Westem blotting.RESULTS: No neurofilament protein expression was found in MDSCs before induction, and neurofilament protein-positive MDSCs were detected following induction. Results of gel electrophoresis and Westam blot showed that no significant differences in NF-kB inhibitor protein expression were determined in the control group, and NF-kB inhibitor protein expression was significantly decreased in the induction group after induction.CONCLUSION: CNTF and Compound Salvia Miltiorrhiza Injection could inhibit the activation of NF-kB and induce the differentiation of MDSCs into neuron-like cells.Zeng XY, Wang W, Sun L, Zhang L, Zeng LD.Differentiation of muscle-derived stem cells into neuron-like cells induced by ciliary neurotrophic factor and Compound Salvia Miltiorrhiza Injection in vitro.Zhongguo Zuzhi Gongcheng Yanjiu yu Linchuang Kangfu.2009;13(27): 5336-5340.

Objective To discuss the feasibility of stone removal in laparoscopic choledocholithotomy by routine laparotomic instruments. Methods A total of 73 patients with common bile duct stones were divided randomly into 2 groups: the Experimental Group received laparoscopic stone removal by routine laparotomic instruments; the Control Group received stone removal by choledochoscopic net-basket. The stone-free rate, operative time, total hospitalization costs and postoperative complications between the two groups were compared. Results There were no statistical significances in stone-free rate between the Experimental Group ( 94.4% , 34/36) and the Control Group (94.6%, 35/37) ( ? 2=0.000, P =1.000). The operative time in the Experimental Group (150.9 min?26.8 min) was shorter than that in the Control Group (172.3 min?28.6 min) ( t=3.297, P =0.002), whereas the total hospitalization costs in the Experimental Group (4400 yuan?1100 yuan) was lower than that in the Control Group (5000 yuan?1300 yuan) ( t=2.126, P= 0.037). No severe operation-related complications were observed in both of the groups. Conclusions Laparoscopic choledocholithotomy by either routine laparotomic instruments or choledochoscopy is safe and effective. Stone removal by routine laparotomic instruments has the advantages of low costs and short operative time.

Objective To discuss the effective surgical treatment of intrahepatic lithiasis combined with high hepa-t ic duct strictures. Methods Two hundreds and sixteen cases of intra hepatic lithiasis and high hepatic duct strictures treated in this hospital fr om January 1993 to October 2002 were analysed retrospectively.Results One hundred and eighty- three cases underwent different selective operation by selected time; 33 case s complicated with acute obstructive suppurative cholangitis underwent emergency were performed single biliary drainage, in which 30 cases were re-operated. Th e operative procedure were: hepatic lobectomy,high cholangiotomy and plastic repair,exposure of hepatic duct of the 2nd and the 3rd order,and plastic re pair with own patch and choledochojejunostomy.Two hundreds and six cases w ere cured,the curative rate was 95.4%; 8 cases improved (3.7 %), and 2 cases died (0.9%).Conclusion The best effective surgical treat ment of intrahpatic lithiasis is hepatic lobectomy. Exposure of hepatic duct of the 2nd and the 3rd order is a satisfactory to release the hepatic duct str ictures and to clear the intrahepatic lithiasis. For patients with normal extr ahepatic bile duct and Oddi's function, plastic repair of bile duct with own patch is possible to keep the normal form and function. Cholang ioscopy may play an important role in the treatment of intrahepatic tr act lithiasis during operation.
