Objective To explore the relationship between long chain non-coding RNA metastasis-associated lung adenocarcinoma transcript 1 (MALAT1) and prognosis of hepatocellular carcinoma, and to provide evidence for perioperative treatment. Methods One hundred and twenty five samples from patients with hepatocellular carcinoma treated in Tianjin Unite Medicine Center Hospital during June 2008 to June 2014 were collected in this study. The expression of MALAT1 was detected by using real-time quantitative PCR (RT-qPCR). The relationship between MALAT1 expression level and prognosis of patients with hepatectomy was analyzed. The risk factors affecting the prognosis of patients were determined. Results The expression level of MALAT1 was significantly higher in hepatocellular carcinoma samples (P<0.05). There was no relationship between the expression of MALAT1 with age, hepatitis B history, cirrhosis history, tumor size, tumor number, tumor TNM stage, vascular invasion, pathological differentiation and preoperative alpha-fetoprotein (AFP) level (P>0.05). The survival rate was calculated with Kaplan-Meier method. The overall 1-, 3-and 5-year survival rates in low level MALAT1 group were 85.9%, 55.2% and 33.8%. The overall 1-, 3- and 5-year survival rates in high level MALAT1 group were 66.0%, 34.6%and 3.9%, respectively. There was significant difference in survival rate between the two groups (P<0.01). The multivariate COX regression model analysis showed that the independent risk factors for postoperative survival rate in patients with hepatocellular carcinoma included tumor vascular invasion (RR=3.055, 95%CI:1.986-4.053, P<0.01) and over expression of MALAT1 (RR=2.918, 95%CI:1.736-3.672, P<0.01). Conclusion Long chain non-coding RNA MALAT1 is a novel tumor marker for prognosis of hepatectomy in patients with hepatocellular carcinoma, which can be used for preoperative and postoperative evaluation in patients with hepatocellular carcinoma.

Objective To investigate the effect of TanshinoneⅡA on nerve conduction of oxaliplatin induced peripheral neuropathy in rats. Methods Fifty Wistar rats were randomly divided into normal control group, model group, treatment group, prevention group, prevention and treatment group. Except for those in model group, Wistar rats were injected i.p. with oxaliplatin (20 mg/kg). The electrophysiological instrument were employed to detect the sciatic nerve conduction velocity, latency, amplitude 6 h, 24 h, 72 h and 7 d after modeling. Results In the model group, velocity of sciatic nerve conduction slowed, and latency prolonged 24 h after modeling (P<0.05) which continued to slow and prolong until 7 d after modeling (P<0.05). After the application of Tanshinone ⅡA, nerve conduction velocity became faster and latency shorter significantly (P <0.05), especially in the prevention and treatment group, in which no significant difference was found when compared with those in the normal control group (P > 0.05). Conclusions During the chemotherapy with oxaliplatin , TanshinoneⅡA can increase the conduction velocity of sciatic nerve , shorten the disease duration and play a protective role for peripheral nerve.

A comparison was made between the research group and control group.Results①Dr and Ds in research group were both lower than those in control group (P<0.05), butθr,θs andθ were all higher than those in control group (P<0.05).②Dr and Ds showed a gradual increase (P<0.05) whilstθr presented a gradual decrease before the treatment, after the fifth treatment and after the tenth treatment (P<0.05).Conclusion Natural childbirth may damage the function of pelvicfloor; electrical stimulation of pelvic therapy is effective on postpartum pelvicfloor rehabilitation; and transperineal sonography can objectively assess the effect of this therapy.

BACKGROUND:It has been an urgent problem of how to promote cartilage repair of the knee and shorten the total course through a tissue engineering approach. Fortunately, microfracture plus stem cel transplantation may open up a new path for this issue. OBJECTIVE:To investigate the clinic feasibility of arthroscopic microfracture technique plus stem cel transplantation for repair of articular cartilage injury of the knee. METHODS:From October 2010 to March 2012, a total of 16 patients with articular cartilage injury of the knee were enrol ed, including 12 males and 4 females, with the average age of 38.6 years (16-52). Al cases of cartilage injury were confirmed by arthroscopy. Autologous bone marrow was extracted from patients at 2 weeks before treatment to isolate, culture and amplify bone marrow mesenchymal stem cel s in vitro. The cel culture solution of 3-5 mL (about 107 cel s) was harvested. The articular cavity was clean by arthroscopy and microfracture technique was performed at the area of cartilage injury that was then covered with hemostatic gauze through a minimal y invasive incision and the prepared bone marrow mesenchymal stem cel s were injected. The knee was bandaged with the elastic bandage after aspirating the joint cavity effusion by vacuum suction. Functional exercises were performed early by CPM.RESULTS AND CONCLUSION:After fol ow-up of 4-18 months, there were 13 cases of excel ent, 2 cases of valid and 1 case of ineffective. According to Lysholm knee scores, the average scores were improved from 42 points (33-67 points) to 89 points (75-99 points) at 4 weeks after treatment. The function was satisfied and al patients were fol owed up without recurrence or worse. Under the arthroscopy, the combination of microfracture technique and autologous bone marrow mesenchymal stem cel transplantation is proved to be effective for articular cartilage injury of the knee and it can notably improve the clinic symptoms and recover the function of the knee.

Objectives To compare the safety and efficacy of radial artery access versus femoral artery access for percutaneous coronary intervention in acute myocardial infarction population. Methods From June 2004 to December 2006, 446 patients with acute myocardial infarction treated with percutaneous stenting were reviewed retrospectively. The radial artery approach was used in 242 patients, and the femoral artery approach in 204 patients. The success of the procedure, procedure duration, X-ray exposition, volume of contrast, incidence of major adverse cardiac events and complications were compared between the radial artery and femoral artery approach. Results Total procedure duration, X-ray exposition, the immediate success of the procedure and the proportion of patients with reperfusion time above 60min are higher in patients with radial artery acess than that with femoral artery access [(62. 1 ± 23. 4) min vs(56. 8 ± 16. 7)min,(2829. 4 ± 1365.2) mGY vs (2352. 3 ± 903.1) mGY, 4% vs 0.9% and 7.44% vs 2.94%respectively, all P ＜ 0. 05]. Conclusions In non-selected patients with acute myocardial infarction treated with primary stent implantation, the success rate of the radial artery approach is lower than the femoral artery approach and could prolong the reperfusion time. It is suitable to change artery access immediately if abnormality is found via radial artery access.
