Objective To investigate the feasibility and safety of reoperation of laparoscopic common bile duct exploration in the management of choledocholithiasis in patients with biliary surgical history. Methods Thirty-one patients with choledocholithiasis and biliary surgical history were performed by reoperation of laparoscopic common bile duct exploration between January 2012 and January 2014 in our hospital.The adhesion was disconnected under the laparoscopy, and then the common bile duct was opened to introduce an endoscope for stone removal.A T-tube was placed for drainage. Results The operations were successfully completed in all the 31 cases, without conversion to open surgery.The vital signs of those patients were smooth during the operation.The operation time was 65-125 min, with a mean of (118 ±21) min.The volume of blood loss was 10-75 ml during operations, with a mean of (39 ±19) ml.The patients could take food normally 24-48 h after operation, with a mean of (27 ±13) h.The drainage tubes were pulled out 48 -72 hours after operation.No severe complications, such as residual stones, bleeding, gastrointestinal leakage, or pancreatitis happened during hospitalization, except for 1 case of biliary leakage and 1 case of incision infection.The patients stayed in hospital for 6-9 days after operation, with a mean of (7.0 ±1.5) days.No biliary stricture or recurrence was found during a 3-24 months of follow-up (mean, 15.6 months) in 31 cases. Conclusion Reoperation of laparoscopic common bile duct exploration by experienced laparoscopic specialists for choledocholithiasis in patients with biliary surgical history is relatively safe and effective.

Objective To investigate the effect of matrix metalloproteinase(MMP-2) in the attack of exprimental autoimmune myositis(EAM) rats, and the effects of methylprednisolone on expressions of gene mRNA and protein of MMP-2. Methods The expression levels of MMP-2 in the peripheral blood, spleen lymphocytes and muscles were detected by using RT-PCR and immunohistochemistry techniques and was compared among EAM group,EAM with methylprednisolone treatment group (EAMM) and control group. Results ⑴ The degree of episode in EAMM group was lower than that of EAM group , and the infiltration of the inflammatory cells and the necrosis of the muscles were also mild in EAMM group. ⑵There was significant upregulation of the expression of the MMP-2 gene mRNA in the lymphocytes of peripheral bood and spleen of EAM rats as compared with that of the control,Elevation of the expression of MMP-2 protein in rats muscles tissues of EAMM group was observed obviously. However, the expression of the mRNA and the protein of MMP-2 was suppressed significantly in EAM group compared with control group. Conclusions The upregulation of the expression of MMP-2 may be correlated with the onset of EAM. Methylprednisolone may relieve the degree of the pathology of EAM by the downregulation of MMP-2 .

OBJECTIVE: To observe the effect of electroacupuncture (EA) of "Jiaji" (EX-B 2) on limb locomotor function and expression of Ras homolog gene family member A (RhoA), Rho-associated kinase Ⅱ (ROCK Ⅱ) and myosin light chain (MLC) proteins in the anterior horn of spinal cord in acute spinal cord injury (ASCI) rats, so as to explore its mechanisms under-lying improvement of SCI-induced limb locomotor dysfunction. METHODS: Forty-eight female Wistar rats were randomly divided into sham operation (sham), ASCI model (model), EA EX-B 2 (EA) and ROCK inhibitor (Fasudil) groups which were further divided into 14 d and 28 d subgroups (n=6 in each). The ASCI model was made by using weight drop striking method. Three hours after modeling, EA (100 Hz, 0.4, 0.6 mA) was applied to EX-B 2 (T 9, T 11) for 30 min, once daily for 14 d and 28 d, respectively. The ROCK inhibitor (hydrochloride Fasudil, 10 mg/kg) was administrated by intraperitoneal injection immediately after modeling, once a day, continuously for 14 d or 28 d. The expression of RhoA, ROCK Ⅱ and MLC proteins in the spinal cord anterior horn tissue (T 10) was detected by immunohistochemistry. The rats' hindlimb locomotor function was assessed according to Basso, Beattie and Bresnahan (BBB) locomotor rating scale (21-points). RESULTS: After ASCI, the BBB scores were significantly lower in the model group than in the sham group on day 14 and 28 (P<0.05), and obviously higher in the EA and inhibitor groups than in the model group (P<0.05), suggesting an improvement of the hindlimb locomotor function after EA intervention or suppression of ROCK. Immunohistochemical results indicated that the numbers of RhoA, ROCK Ⅱ and MLC immune-reaction positive cells in the anterior horn of spinal cord were significantly more in the model group than in the sham group (P<0.05), and remarkably decreased in both EA and inhibitor groups on day 14 and 28 relevant to the model group (P<0.05). The therapeutic effects of EA were markedly weaker than those of inhibitor Fasudil in up-regulating BBB score and down-regulating the number of RhoA, ROCK Ⅱ and MLC positive cells (P<0.05). CONCLUSION: EA of EX-B 2 can improve the hindlimb locomotor function in ASCI rats, which may be associated with its effect in down-regulating the expression of RhoA, ROCK Ⅱ and MLC proteins (i.e., inhibiting the RhoA/ROCK signaling pathway) in the anterior horn of spinal cord.
