OBJECTIVETo study the effect of nadroparin in the migration of breast cancer cells MDA-MB-231 and its action mechanism.

METHODThe MTT test was adopted to observe the effect of different concentrations of naringenin on the growth capacity of breast cancer cells MDA-MB-231. Wound healing and transwell experiment analysis were conducted to detect the effect of naringenin on the migration of breast cancer cells MDA-MB-231. Western blotting was adopted to investigate the effect of naringenin on protein expressions of MDA-MB-231 cell Integrin β3, β1 and matrix metalloproteinase MMP-2 and MMP-9. The computer virtual docking technique was used to evaluate the combining capacity of naringenin and Integrin β3 in vitro.

RESULTNaringenin inhibited the migration of MDA-MB-231 cells in a dose-dependent manner. In wound healing and transwell experiments, with the increase in the concentration of naringenin, the number of migrant MDA-MB-231 cells and the invasion capacity of breast cancer cells decreased. Naringenin could inhibit the protein expression of Integrin β3 in a dose-dependent manner, but with unobvious effect on expression of Integrin β1. Besides, naringenin could significantly inhibit the protein expressions of MMP-2 and MMP-9. The results of the computer virtual docking showed a negative value in the combining capacity between naringenin and Integrin β3, indicating the high affinity between them.

CONCLUSIONNaringenin can inhibit the growth capacity of breast cancer cells MDA-MB-231 and block the migration and invasion of breast cancer cells MDA-MB-231. Its mechanism is to down-regulate MMP-2 and MMP-9 expressions after combining with Integrin β3.

OBJECTIVE:To comparison the clinical efficacy and safety of sitagliptin and Repaglinide in the treatment of new-ly diagnosed patients with type 2 diabetes mellitus. METHODS:214 newly diagnosed patients with type 2 diabetes mellitus were randomly divided into study group and control group with 107 cases in each group according to random number table method. Both group received routine diabetes diet,health education and suitable exercise. Control group was treated with Repaglinide tablet 1.0 mg,tid;while study group was treat with Sitagliptin tablet 100 mg,qd. Lab indexes,FBG,PBG,HbA1c and BMI were observed in 2 groups before and after treatment. ADR were compared between 2 groups. RESULTS:There was no statistical significance in lab indexes between 2 groups before and after treatment (P>0.05). After treatment,FBG,PBG,HbA1c were significantly de-creased significantly in 2 groups,with statistical significance (P<0.05),there was no statistical significance between 2 groups (P>0.05). BMI of 2 groups were increased significantly,and the study group was higher than the contrd group,with statistical sighificance (P<0.05). Patients in the study group had no hypoglycemia,while 3 patients in the control group suffered from it, there was statistical significance (P>0.05). CONCLUSIONS:Sitagliptin is similar with repaglinide in therapeutic efficacy;both can effectively reduce blood glucose of elderly patients with newly diagnosed type 2 diabetes mellitus,and the incidence of hypo-glycemia was low,the saterty was good,but sitagliptin has a better control of BMI in patients.

AlM: To evaluate the clinical efficacy of canalicular intubation combined with external dacryocystorhinostomy ( ext-DCR ) for treatment of chronic dacryocystitis and upper lacrimal duct stenosis.
METHODS:Thirty-three patients (33 eyes) with chronic dacryocystitis and upper lacrimal duct stenosis who underwent canalicular intubation combined ext-DCR were retrospective analyzed. The silicon tube was indwelt for 6mo. All cases were re-examined 1wk;1, 3, 6, 9mo post-operation, flow of tears, pus excretion and lacrimal duct clearance were observed.
RESULTS: Clear lacrimal duct ratio was 100% in all cases during 1wk~6mo post-operation; Silicon tube was removed 6mo post-operation, 3mo after tube removal, rechecking reported 32 cases with clear lacrimal duct (97%) and 1 case with resistant duct (3%). Two cases ( 6%) with minor lacerations, no other complications were observed.
CONCLUSlON: Canalicular intubation combined ext-DCR is an effective treatment for chronic dacryocystitis and upper lacrimal duct stenosis.

Objective: To investigate the effect of interleukin-8 (IL-8) on survival and apoptosis of hypoxic human umbilical vein endothelial cells (HUVECs) with its mechanisms.
Methods: Hypoxic HUVECs were induced by CoCl2. HUVECs were cultured with different concentrations of CoCl2 or IL-8 and the survival rates of HUVECs were examined. Normal or hypoxic HUVECs were incubated with IL-8 or simultaneously incubated with anti-IL-8 or Akt inhibitor LY294002 for 48h. The HUVECs survival rate was detected by MTT method, apoptosis rate was measured by Annexin V-FITC/PI method, the protein expressions of Caspase-3, phosphorylated Akt (pAkt) and GSK-3βser9 (pGSK-3βser9) were evaluated by Western blot analysis.
Results: By 12 h incubation with low concentration of CoCl2 (50, 100 μmol/L), HUVECs proliferation were improved, P<0.01; while by 24h and 48 h incubation with high concentration of CoCl2 (200, 400 μmol/L) HUVECs survival were decreased. By 48h and 72h incubation with IL-8 at (10, 50, 100 ng/ml), the hypoxia induced cell apoptosis was decreased and the survival was increased,P<0.01. IL-8 at 10 ng/ml may obviously inhibit the normal and hypoxic HUVECs apoptosis, down-regulate caspase-3 and up-regulate pAkt and pGSK-3βser9 expressions in HUVECs,P<0.01, while the above effects could be reversed by LY294002 and anti-IL-8,P<0.01.
Conclusion: IL-8 could down-regulate caspase-3 and up-regulate pAkt and pGSK-3βser9 expressions in HUVECs and therefore, inhibit the apoptosis and improve the survival of hypoxic HUVECs.

Objective To observe the clinical efficacy and safety of close-loop muscle relaxant injcction system (CLMRIS) combined with auditory evoked potentials index for monitoring in elderly patients during general anesthesia.Methods A total of 100 patients undergong abdominal operation with ASA Ⅰ-Ⅱ anesthesia in our hospital from February 2012 to October 2012 were selected.Patients were randomly divided into 2 groups:the traditional group (n=50) and the CLMRIS group (n=50).The traditional group was anaesthetized according to clinical experience,and the CLMRIS group was used with the muscle relaxant guided by the close-loop muscle relaxant injection system.The auditory evoked potential (AEP) index and the life index were observed,and the dose of muscle relaxant,the time of consciousness recovery,dynamic response rate during operation and the adverse reaction were recorded at the time points at entering the operating room,induction of anesthesia,tracheal intubation,incision,into the abdominal,exploration,closing abdomen,skin suture,consciousness recovery,tracheal extubation,out of room (T0-T10).Results The vital signs in all patients were stable.The dynamic response rate during operation was lower in the CLMRIS group than in the traditional group at each time points of T8-T10 (all P＜0.05).There was no increase in mean artery pressure (MAP) and heart rate in groups at the time points of T0-T1,T8-T10 (all P＞0.05).The time of tracheal intubation,tracheal extubation and consciousness recovery were shorter in the CLMRIS group than in the traditional group [(268±30.4) min vs.(172±23.7) min,(14±6.4) min us.(18±7.9) min,(8.8±2.9) min vs.(12.2±4.6) min,respectively,t=3.277,6.341,3.346,all P＜0.05].There were no significant differences in AEP index between groups at the time of T0 (P＞0.05),but at the time of T1,the AEP index was lower in CLMRIS group than in the traditional group (P＜0.05).Conclusions The application of close loop muscle relaxant injection system can improve the safety of general anesthesia in the elderly and reduce the incidence of postoperative residual paralysis.The CLMRIS combined with the auditory evoked potential for monitoring depth of anesthesia can prevent and reduce the incidence of intraoperative awareness,has a strong controllability in general anesthesia with smooth induction,and can reduce the dose of anesthetic drugs to achieve the best anesthetic effect.
