Objective To observe the inhibitory effect of matrine on K-ras gene mutation colon cancer, and to clarify the inhibitory mechanism. Methods SW480 cells were treated with different concentrations of matrine. MTS method was used to detect the proliferation of SW480 cell lines. The apoptosis of SW480 cells was measured by flow cytometry. The migration of SW480 cells was examined by the scratch test. The expression of MEK1/2 protein was detected by Western blotting method. Results Compared with the blank control group, matrine (0.125-1 mg/mL) could inhibit the growth and proliferation of human colorectal cancer SW480 cell lines, promote the apoptosis, restrain the migration of SW480 cells, and inhibit the expression of MEK1/2 protein(P < 0.05), the effect showing a dose-dependent trend. Conclusion Matrine can effectively inhibit the proliferation and migration of SW480 cells, and promote SW480 cell apoptosis through the down-regulation of MEK1/2 protein expression in MAPK signal pathway system.

OBJECTIVE:To observe the clinical efficacy and safety of flupirtine maleate combined with amitriptyline in the treatment of thalamic pain after stroke. METHODS:A total of 70 patients with thalamic pain after stroke in our hospital during Jan. 2016-Aug. 2017 were divided into control group(34 cases)and observation group(36 cases)according to random number table. Both groups received secondary prevention therapy of stroke. Based on it,control group was given Amitriptyline hydrochloride tablet 25 mg/time orally,tid. Observation group was additionally given Flupirtine maleate capsule 0.1 g/time orally,tid,on the basis of control group. Treatment course of 2 groups lasted for 4 weeks. VAS,HAMD17 and HAMA14 scores of 2 groups evaluated before treatment,after 1,2,3,4 weeks of treatment Clinical efficacies and the occurrence of ADR were observed in 2 groups. RESULTS:Before treatment,there was no statistical significance in the scores of VAS,HAMD17 or HAMA14 between 2 groups(P>0.05). VAS score and HAMD17 score of observation group after 1,2,3,4 weeks of treatment,those of control group after 2,3 and 4 weeks of treatment were significantly lower than before treatment;the observation group was significantly lower than the control group at different time periods(P<0.05 or P<0.01). HAMA14 score of 2 groups after 2,3,4 weeks of treatment were significantly lower than before treatment;the observation group was significantly lower than the control group at different time periods(P<0.05 or P<0.01). Total efficiency rate(91.67%)of observation group were significantly higher than that(67.65%)of control group(P<0.05). There was no statistical significance in the incidence of ADR between 2 groups (11.76% vs. 11.11%)(P>0.05). CONCLUSIONS:Flupirtine maleate combined with amitriptyline can effectively relieve thalamic pain after stroke,and improve post-stroke,anxiety depression,which are better than control group,and the incidence of ADR is familar to control group.

OBJECTIVETo investigate the safety and feasibility of laparoscopic radical right hemicolectomy using caudal-to-cranial approach (yellow-white borderline between right mesostenium and retroperitoneal is firstly cut as the entry to dissect the fusion fascial space between the visceral and parietal peritoneum, which is called caudal-to-cranial approach for right hemicolectomy).

METHODSFrom January 2014 to May 2015, 76 consecutive patients with right side colon cancer underwent laparoscopic radical right hemicolectomy using caudal-to-cranial approach. The baseline characteristics, intraoperative and postoperative outcomes were prospective collected and reviewed retrospectively.

RESULTSAll the 76 patients completed operations successfully, and one patient (1.3%) was converted to open surgery because of intraoperative bleeding due to unexpected injury of ileocolic artery. The mean operative time was (152.8±42.1) min with a mean estimated blood loss of (70.4±43.5) ml. The mean time of first flatus was (49.3±22.9) h and mean liquid oral intake was (58.5±17.6) h. The postoperative complications appeared in 7 patients (9.2%), including one (1.3%) of pulmonary infection, one(1.3%) of urinary system infection, two (2.6%) of wound infection, two (2.6%) of inflammatory bowel obstruction and one (1.3%) of lymphatic fistula, and they were all cured with conservative treatments. The postoperative hospital stay was (7.8±5.4) d. The mean number of harvested lymph node was 34.2±10.9, among which 4.1±2.8 was positive.

CONCLUSIONSLaparoscopic radical right hemicolectomy using caudal-to-cranial approach is safe and feasible.
