OBJECTIVE:To observe the clinical efficacy and ADR of Mirabilite combined with intrapetitoneal in the treatment of elderly colorectal malignant ascites. METHODS:77 cases of patients with elderly colorectal malignant ascites were randomly di-vided into treatment group (n=40) and control group (n=37). The control group received the treatment of intraperitoneal alone, while the treatment group was based on the control group additionally received Mirabilite combined with intrapetitoneal. The clini-cal efficacy,quality of life (QOL),and ADR in 2 groups were compared and statistically analyzed. RESULTS:Compared with control group,the effective rate in treatment group was 77.5% and the disease control rate was 87.5%,with significant difference (P<0.05);the QOL score in treatment group was better than control group,with significant difference(P<0.05);the incidence of local ADR in Mirabilite for external use was low. CONCLUSIONS:Mirabilite combined with intraperitoneal has better efficacy in the elderly colorectal malignant ascites and better QOL.

Objective To investigate the expression pattern of skeletal muscle specific miR-206,myogenesis related myoD which change with time in dcnervated muscle atrophy rats.Methods From June,2015 to January,2016,40 SPF sprague-dawley rats were equally classified into 5 groups randomly according to standard settled before,5 groups were separately defined as denervated 0d group,denervated 1d group,denervated 7d group,denervated 14d group,and denervated 28d group.Each group contained 8 rats.The rats atrophy models were established by cutting sciatic never on left side.According to the different denervated time,the gastrocnemii on both sides were obtained under anesthesia,respectively.The wet weight ratio of two compared gastrocnemii were measured,and the gastrocnemii transection was observed by HE stain,measured the expression of myoD protein by western blot,obtained the expression of miR-206,myoD mRNA by qPCR.Results According to our study on rats denervated atrophy models,the wet ratio of compared gastrocnemius would decrease rapidly,by HE stain,decease of cross sectional area in muscle fiber was observed as well as degeneration.Collagen fibers hyperplasia appeared and increased with time change.Wet ratio and transaction aera ratio of group Od,1d,7d,14d,28d were 0.99±0.04,0.92±0.07,0.68±0.11,0.39±0.06,0.27±0.07 and 0.99±0.02,0.96±0.04,0.51±0.09,0.34±0.08,0.23±０.03 respectively,difference between experimental groups and control group were statistically significant (P＜ 0.05),the differences between each experimental groups were also statistically significant (P＜ 0.05).After qPCR test of miR-206,myoD mRNA expression,it was found that their expression patterns were similar,miR-206,myoD mRNA increased at first and would reach the expression peak at the 7 th day,after that their contents decreased but still higher at the 14th day when compared with that at the 1 st day.Their expression of group 0d,1 d,7d,14d,28d were 0.24±0.06,0.34±0.04,0.68±0.04,0.49± 0.07,0.25±0.03 and 0.41 ±0.06,0.49±0.09,0.93±0.06,0.66±0.03,0.39±0.04,respectively.All experimental groups were statistically significant different when compared with 0d group except 1d group (P＜ 0.05),the differences between each experimental groups were also statistically significant(P＜ 0.05).The protein expression of myoD was also measured by western blot test,which showed nearly the same expression pattern as the mRNA expression pattern.After injury,the protein expression increased and reached the expression peak at the 7th day.The relative expression of myoD of group 0d,1d,7d,14d,28d measured by grey ratio were 1.03±0.05,1.06±0.06,1.42±0.10,0.66±0.13,0.24±0.07,respectively.The difference between experimental groups and control group were statistically significant (P ＜ 0.05),the differences between each experimental groups were statistically significant (P ＜ 0.05) as well.Conclusion The degree of muscle denervation atrophy was related to the denervated duration in rats.The expression regulation of miR-206 and myoD in gastrocnemius was similar during the muscle denervation atrophy,which suggesting having internal relationship between miR-206 and myoD.

Objective To explore the changes of left atrial systolic function in patients with coronary heart disease after coronary artery bypass grafting (CABG). Methods Strain rate imaging (SRI) was performed on 23 patients with coronary heart disease before CABG, 1 week, 1 and 3 months after CABG to evaluate left atrial systolic function quantitatively. Results No significant change of left atrial systolic function was detected 1 week after CABG (P＞0.05 ). E/A and LVEF increased, LAFS, AEF and SRa decreased 1 month after CABG compared with those before CABG (P＜0.05). Three months after CABG, changes turned more significantly (P＜0.01). Left ventricular ejection fraction (LVEF) increased 1 and 3 months after CABG, and its changing rate negatively correlated with those of Sra (r=-0.751,-0.783; all P＜0.01). Conclusion Left atrial systolic function is affected by CABG, presenting as decrease of pump function. SRI can be used to evaluate the atrial systolic function quantitatively and monitor the changing of left atrial systolic function dynamically after CABG.

Objective To explore the effect of coronary artery bypass grafting(CABG) on left atrial (LA) function by strain rate imaging(SRI). Methods Twenty-three patients with coronary heart disease who underwent coronary artery bypass grafting were involved. SRI was performed on those patients to evaluate LA function quantitatively at baseline (before CABG),and at 1 week, 1 month and 3 months after CABG. Peak strain rate(SR) was measured at each segment (septal, lateral, posterior, anterior, and inferior walls) and mean peak systolic SR (SRs),peak early diastolic SR (SRe) and peak atrial systolic SR (SRa) were calculated by averaging data in each segment. Results Compared with the baseline,LV pre-systolic volume(LAVp), maximal volume (LAVmax), minimal volume (LAVmin), LV active emptying fraction (LAAEF) and passive empting fraction(LAPEF) had on significant differences at 1 week (P >0.05). LAVp,LAVmin,LAVmax and LAAEF decreased gradually after CABG, LAPEF increased gradually after CABG (P <0.05). Compared with the baseline, the peaks of SR curve showed no significant differences at 1 week (P >0.05). Nevertheless,the peaks of SR were increased at systole and early diastole,decreased at atrial contraction at 1 month (P <0.05). Those changes were turned more significantly at 3 months (P 0.01). Left ventricular ejection fraction (LVEF) both increased at 1 month and 3 months,and its changing rate correlated inversely with the changing rate of SRa respectively (r = -0.751, -0.783,all P<0.01).Conclusions LA function is affected by CABG, presented as reservoir and pump functions decreased and conduit function increased. SRI can evaluate the atrial function quantitatively and monitor the changing of LA function dynamically after CABG.

Aurora-B as an important kinase to adjust the cell normal mitosis is a potent target for cancer treatment. Aurora-B is overexpressed in a broad range of tumor and tumor cells are more sensitive while Aurora-B is inhibited. Due to the key role of the Aurora-B in cell mitosis, the development of its inhibitors is becoming more and more important. Several small molecules inhibit with a similar efficacy both Aurora-A and Aurora-B, however, in most cases the effects resemble Aurora-B disruption by genetic methods, indicating that Aurora-B represents an effective therapeutic target. There were several Aurora-B kinase inhibitors which had entered the clinics and displayed good antitumor activity. In this review, we will outline the functions of Aurora kinase B in normal cell division and in malignancy. We will focus on recent preclinical and clinical studies that have explored the mechanism of action and clinical effect of Aurora-B inhibitors in cancer treatment.

Objective To observe the application effect of the risk of ovarian malignancy algorithm(ROMA)in screening ovarian cancer among high risk population.Methods The human epididymis protein 4(HE4)and carbohydrate antigen 125 (CA125 )were detected in 1 753 cases of high risk for overian cancer,56 cases of ovarian cancer(positive control)and 60 healthy people,patients. Then the ROMA value was calculated in combination with the subject′s menstruation status.The detection results were analyzed and compared among groups.The high risk group for ovarian cancer devided according to the ROMA value was further performed the confirmatory test and the low risk group was monitored by follow up.The detection rates of ovarian cancer were compared be-tween the two subgroups.Results In the high risk population,the diagnostic performance of the ROMA value for ovarian cancer was superior to that of the single HE4 or CA125;the ROMA value had statistically significant difference between the high risk sub-group in the high-risk population with ovarian cancer or the healthy control group(P <0.05);in 1 753 cases of high risk popula-tion,37 cases were included in the high risk subgroup,in which 3 cases of ovarian cancer were screened out and in clinical early stage.The detection rate of ovarian cancer in the high risk subgroup was 8.1%.No case of ovarian cancer was detected out in the low risk subgroup.Conclusion The ROMA value is conducive to early screening for ovarian cancer in the high risk population, which can save the medical cost and increase the detection rate.

AIM: To explore the neuroprotective action of progesterone(PROG), which has been proved to be a "neuroactive steroid". METHODS: The model of focal cerebral ischemia was established in rats by reverserble inserting a nylon thread with a diameter of 0.2 mm into the anterior cerebral artery through the internal carotid artery. The effect of PROG was assessed by determining water,sodium, potassium, and calcium contents in striatum of rats subjected to 2 h ischemia followed by 22 h reperfusion. RESULTS: The water,sodium,and calcium contents of middle cerebral artery occlusion(MCAO) striatum were obviously higher,the potassium content was obviously lower than those of non-MCAO striatum in I/R and DMSO groups,but there was no significant difference between these two groups.Compared with the result in I/R and DMSO groups , water, sodium and calcium contents significantly decreased, but potassium(P0.05). CONCLUSION: Treatment with PROG can significantly reduce the striatal injury of rats with cerebral ischmia-reperfusion.

AIM: To explore the role of NO in the induction of brain ischemic tolerance (BIT) by observing changes of NOS activity and NO_2-/NO_3- content following a transient cerebral ischemia. METHODS: The rat 4-vessel occluding brain ischemic model was used. 140 male Wistar rats were divided into sham, cerebral ischemic preconditioning (CIP), ischemic insult and CIP+ischemic insult groups. An occlusion of the 4 vessels for 3 min was normally used as CIP, and a relative long one for 10 min was used as ischemic insult. When CIP was followed by ischemic insult, the interval between them was 3 d. The CA1 region of the hippocampus of rats was dissected out at 0 h, 2 h, 16 h, 24 h, 36 h, 72 h and 7 d after the last time of ischemia to assay its NOS activity and NO_2-/NO_3- content. RESULTS: The NOS activity and NO_2-/NO_3- content began to increase at 16 h, peaked at 24 h and decreased to basal level at 36 h of reperfusion after CIP. The duration of the up-regulation of NOS activity and NO_2-/NO_3- content was much shorter than that of BIT, which usually takes place 1-7 d after CIP. The pattern of upregulation of the NOS activity and NO_2-/NO_3- content was similar to the CIP group, but the maximum (24 h) was much more than that in CIP group (P
