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.

Clinicopathological parameters are important to predict the prognosis of esophageal squamous cell carcinoma (ESCC),they mainly include TNM stage related indexes of the tumor,tumor length,vessel and nerve invasion, tumor budding, peripheral blood cells, etc. To predict the prognosis of ESCC patients accurately is the prerequisite of precise treatment and the key to improve the patients survival rate and survival quality.

OBJECTIVETo detect the clinical value of the ECT bone scan in evaluating of the situation of infection control after hip knee arthroplasty.

METHODSThe clinical data were retrospectively analyzed in 62 patients, including 34 males and 28 females with an average age of 68.8 years old ranging from 65 to 74 years. The results of ECT bone scan, erythrocyte sedimentation rate, C-reactive protein were used to assess periprosthetic infection. The patients with positive ECT and ESR on CRP were considered to have periprosthetic infection; however, the patients with two or more negative, indexes were considered to have no infection.

RESULTSThe sensitivity, specificity, accurate rate of ECT were 75.0%, 88.9%, 87.1% respectively; ESR 50.0%, 72.2%, 69.4%; CRP 62.5%, 81.4%, 79.0%. The combination of the three methods were 87.5%, 96.3% and 95.2%,

CONCLUSIONCompared with ESR and CRP, ECT is a more effective way in the diagnosis of periprosthetic infection, which has great value and is worth popularizing.

Total hip arthroplasty (THA) is a vital therapeutic tool for hip terminal disease. Frequently, hidden blood loss exists in the postoperation, which seriously affect the postoperative rehabilitation of patients. It is urgent need to solve the problem that how to fundamentally prevent and reduce hidden blood loss after THA. Although THA has its own operational reason in blood loss, and also relates to a variety of risk factors, the mechanism of hidden blood loss is not clear. Tranexamic acid has a significant role in preventing perioperative blood loss, and the correlation of hidden blood loss and fibrinolytic mechanism would be confirm necessarily in the future,which will produce positive significance in completing the mechanism of hidden blood loss.

BACKGROUND:Studies have shown that intramuscular transplantation of xenogeneic umbilical cord mesenchymal stem cel s in a certain dose range is safe and reliable, and it also confirm that this approach is equal y safe and effective for heart failure in rats with dilated cardiomyopathy. OBJECTIVE:To explore the effect of human umbilical cord mesenchymal stem cel s through intramuscular injection on the cytokine expression in adriamycin-induced dilated cardiomyopathy (DCM) rats. METHODS:Total y 160 rats were randomly divided into control group (n=20) and DCM group (n=140). Rats in the DCM group were administered adriamycin intraperitoneal y to establish DCM model. The DCM rats were randomly subdivided into model control group (served as model group), cel supernatant group, the low-dose mesenchymal stem cel group (served as low-dose group), the middle-dose mesenchymal stem cel group (served as middle-dose group), and the high-dose mesenchymal stem cel s group (served as high-dose group). Secondary injection was performed at 4 weeks after first injection. RESULTS AND CONCLUSION:The ELISA test showed that the serum levels of vascular endothelial growth factor (VEGF), hepatocyte growth factor (HGF), leukemia inhibitor factor (LIF) and granulocyte macrophage colony stimulating factor (GM-CSF) were higher in the model group than the control group before and after intramuscular injection (P<0.05). After intramuscular injection, the levels of HGF, LIF, GM-CSF and VEGF in the low-dose group were increased significantly (P<0.05), which were significantly higher than those in the model group (P<0.05). The level of LIF in the middle-dose group was significantly elevated after injection (P<0.05), while there were no significant differences in HGF, VEGF and GM-CSF levels in the high-dose group before and after intramuscular injection (P>0.05). Both the immunohistochemical and RT-PCR results showed that the expressions of insulin-like growth factor-1, VEGF and HGF were increased in al the DCM rats as compared with the control group, which were increased most in the middle-dose group. These findings indicate that low-dose and middle-dose human umbilical cord mesenchymal stem cel s intramuscular injection can increase the serum levels of HGF, LIF, GM-CSF, VEGF and the expressions of IGF-1, HGF and VEGF in the myocardium of DCM rats.

AIM:To investigate the timing and efficacy of vitrectomy for patients with vitreous hemorrhage(VH) due to proliferative diabetic retinopathy(PDR).METHODS:Retrospective analysis.Patients who presented to our hospital between Feburary 2012 and May 2014 with VH secondary to PDR treated with vitrectomy were included.All patients were divided into three groups according to the duration of VH.A group was less than 1mo for 22 eyes, B group was 1-3mo for 23 eyes, C group was more than 3mo for 25 eyes.All patients underwent intravitreal injection of ranibizumab 1-2wk before vitrectomy, and supplemented or finished panretinal photocoagulation (PRP) intraoperatively or postoperatively.Patients with cataract accepted phacoemulsification and intraocular lens implantation.Eyes filling silicone oil were implanted intraocular lens in the second phase.All patients were followed up 24 to 42mo (mean:28.7mo).We assessed the intraoperative complications such as hemorrhage, iatrogenic retinal hole, and postoperative complications such as vitreous hemorrhage, neovascular glaucoma.Macular edema and best corrected visual acuity were observed at every follow-up.RESULTS:There was no significant difference for other baseline data (P>0.05) but DR stage between three groups (P=0.033).There was significant difference of last follow up visual acuity between three groups (P<0.001).The significant difference can be seen between group A and B (P=0.03).The same outcome showed between Group A and C(P<0.001).There was no significant difference between Group B and C (P>0.05).The percentage of visual acuity was 0.5 and above in the three groups were:41%, 23%, 0 respectively.The patients with visual acuity of less than 0.1 were 5%, 26% and 40% respectively.Silicone oil filling rate of three groups were:9%, 26%, 40% respectively and there was no significantly difference between three groups on postoperative complications (P>0.05).CONCLUSION:Patients with VH due to proliferative diabetic retinopathy undergoing early vitrectomy may get better visual acuity than who accepting delayed vitrectomy.
