2.Progress in correlation of long non-coding RNA with breast cancer invasion and metastasis
Tianjin Medical Journal 2015;43(5):566-569
Long non-coding RNA(lncRNA) is a group of functional RNA molecules, which is more than 200 nucleotides in length and lacks ability of encoding protein. The current study indicates that the abnormal expression of lncRNA is closely related with breast cancer progression. Some lncRNA takes part in regulating the process of breast cancer invasion and metastasis. This article reviews the abnormal expression of lncRNA in breast cancer and the relevance with breast cancer invasion and metastasis, which is expected to provide new strategy for breast cancer diagnosis and treatment.
3.The research progress on cancer multidrug resistance mechanisms
Practical Oncology Journal 2015;(4):364-367
The multidrug resistance( MDR) has become one of the key factors in the success of chemo-therapy.Thus,overcoming multidrug resistance of tumor has become a pressing matter of the moment for tumor therapy.The mechanism of MDR is a very complicated process,influenced by many factors.Therefore,the tumor multidrug resistance mechanisms in depth study will help to select more appropriate anti-tumor drugs.In this re-view,we described about MDR mechanisms researching progress in recent years.

Using the experiences of domestic and other countries on rehabilitation nursing of patients with femoroacetabalar impingement for reference,a balanced rehabilitation procedure was designed and implemented on 16 patients underwent arthroscopic bone forming surgery in acetabulum and femoral head and neck junction.The patients could master the correct metheds of functional exercises.As a result,no postoperative complications occurred.The score of modified Harris hip rating was increased from 62.4 points before surgery to 92.5 points at six months after surgery.

Purpose To investigate the influence of single slow intravenous infusion of dexmedetomidine (Dex) on femoral artery color Doppler hemodynamics during the induction of general anesthesia. Materials and Methods Forty patients of elective abdominal surgery under general anesthesia were elected and randomly divided into Dex group and the control group, with 20 cases in each group. Dex (0.2 μg/kg) 20 ml was injected with intravenous infusion in Dex group, and 20 ml saline was infused in control group, the infusion time was 10 min;then intravenous injection of Sufentanil, Propofol and Rocuronium were performed in turn for the induction of general anesthesia and endotracheal intubation. Femoral artery peak systolic velocity (Vs), early diastolic reverse peak velocity (Vd), systolic diameter (Ds), diastolic diameter (Dd), systolic blood pressure (SBP), diastolic blood pressure (DBP), mean arterial pressure (MAP) and heart rate (HR) changes at each time point were observed and recorded. Results ① Compared with baseline, Vs increased and Vd decreased (P<0.05) 10 min after the infusion of Dex in Dex group;after induction, Vs and Vd in both of the two groups decreased, and the difference between the two groups was not statistically significant (P>0.05);Vs reduced significantly in both of the two groups at the intubation moment and 1, 3, 5 min after intubation, but the Dex group changed more smoothly (P<0.05), and Vd raised in both groups with the Dex group changing more smoothly (P>0.05);Ds and Dd of both groups did not change significantly at each time point (P>0.05). ② Compared with baseline, MAP and HR decreased (P<0.05) after the infusion of Dex in Dex group;after induction, MAP and HR of both groups decreased, and the difference between the two groups was not statistically significant (P>0.05); MAP and HR increased in both groups at intubation moment, but the Dex group changed more smoothly than the control group (P<0.05).③SBP, DBP and HR were negatively correlated with Vs (r=-0.507,-0.619,-0.750, P<0.05) in both groups; SBP, DBP and HR were positively correlated with Vd (r=0.821, 0.881, 0.883, P<0.05) in both groups;there was no significant correlation (r=0.419, P>0.05) between Vs and Vd. Conclusion Single slow intravenous infusion of Dex (0.2μg/kg) can accelerate the femoral artery Vs and slow down the Vd, resulting in more stable hemodynamics during the induction of general anesthesia.

AIM To study the effects of propafenone on Kv 4 2 and Kv4 3 potassium current. METHODS Whole cell patch clamp technique was used to record changes of Kv4 2 and Kv4 3 potassium currents. RESULTS ① Propafenone redu ced the amplitude of Kv4 2 and Kv4 3 currents, in a concentration-dependent, IC 50 was 10 3 and 71 ?mol?L -1 respectively. ② Propafenone inhibi ted Kv4 2 and Kv4 3 current inactivation, 10 ?mol?L -1 propafenone acce lerates Kv4 2 current inactivation constant from (38 9?2 1) ms to (9 9?1 8) ms; and shifted the steady state inactivation curves of Kv4 2 current to negative potentials. 100 ?mol?L -1 Propaf enone accelerates Kv4 3 current inactivation constant from (144 8?20 8) ms t o (18 5?2 8) ms; and shifted the steady state inactivation curves of Kv4 2 c urrent to negative potentials. ③ propafenone inhibited Kv4 2 and Kv4 3 curren t activation, 10 ?mol?L -1 propafenone shifted the steady state activati on curves of Kv4 2 current to negative potentials. 100 ?mol?L -1 propafe none shifted the steady state activation curves of Kv4 2 current to negative po tentials. CONCLUSION Propafenone, maybe, also exerts its effects via blocking Kv4 2 and Kv4 3 current to antiarrhythmia.

Objective To explore the effect of valasartan, an angiotensin Ⅱ type 1 (AT 1) receptor antagonist, on the plasma levels of calcitonin gene-related peptide (CGRP) in patients with essential hypertension. Methods 29 outpatients with essential hypertension were treated with valasartan 80mg/day for 6 weeks. 28 age-matched normal blood pressure people were taken as controls. The plasma levels of CGRP were measured in all patients before and after treatment and in controls. Results The plasma levels of CGRP in hypertensive patients were significantly lower than those in controls (minimal value: 0.00 vs 39.95pg/ml; maximal value: 24.07 vs 155.59pg/ml; P
