Objective To screen microRNA (miRNA) that inhibit expression of the metastasisrelated gene ezrin in ovarian cancer cells and explore their correlation to the invasion and metastasis of ovarian cancer. Methods The differential expression of ezrin in two paired high-metastatic and lowmetastatic cell lines were examined by real time reverse transcription (RT)-PCR and western blot. A functional screen with microarray was employed to identify miRNA that were differentially expressed between SKOV3 and SKOV3ip cell lines. Three programs, TARGETSCAN ( http://www. targetscan. org ),MICROCOSM ( http ://www. ebi. ac. uk/enright-srv/microcosm/htdocs/targets/v5/) and PICTAR (http://www. pictar. mdc-berlin. de), were employed to identify all miRNA, which may inhibit the expression of ezrin and were differentially expressed between SKOV3 and SKOV3ip cells. To test the repressive potential of these miRNA, synthetic mimetics were transfected individually into SKOV3ip cells and endogenous ezrin expression levels monitored by western blot and real-time RT-PCR. Results ( 1 ) The mRNA average level of ezrin were (81.74 ± 5.34) -fold higher expression level in SKOV3ip versus SKOV3 cells ( P ＜ 0. 01 ), while (2. 61 ±0. 14)-fold in HO-8910PM versus HO-8910 cells (P ＜0. 01 ). Elevated protein level of ezrin were observed in SKOV3ip cells compared with that in SKOV3 cells, and the same that in HO-8910PM cells compared with HO-8910 cells. Paired SKOV3 and SKOV3ip cells were employed to study the more significant difference in ezrin expression between them. (2) By a functional screen using miRNA microarray combined with bioinformatics analysis,the miR-183 and miR-22 were indentified as two candidate miRNA,which may have the potential regulatory role in ezrin expression. Real time RT-PCR assays revealed that miR-183 and miR-22 were, respectively, an average of (5.84 ± 0.66)-fold and(6.67 ± 0.67)-fold higher expression level in SKOV3ip versus SKOV3 cells (P ＜0. 01 ), which were in agreement with the microarray data. A subsequent validation by western blot and real time RT-PCR revealed that over-expression of miR-183 and miR-22 could both lead to an obvious decrease in ezrin protein level,while there were not signicant difference in the level of ezrin mRNA( P ＞0. 05 ). Conclusion Increased expression of miR-183 and miR-22 may both repress the protein level of ezrin,indicating that miR-183 and miR-22 may bear a potential role in inhibiting ovarian cancer metastasis in a ezrin-mediated way.

Objective To explore the application of single-person operated mammotome minimally inva-sive surgery in treatment of benign breast lesions. Methods Clinical information of 403 patients were collected and retrospectively analyzed. 262 patients receiving ultrasound guided single-person operated mammotome mini-mally invasive surgery for benign breast masses were selected as the treatment group,141 patients undergoing open surgery for treatment of benign breast masses were selected as the control group.Operative time, introopera-tive blood loss,length of stay,postoperative healing time, as well as the occurrence of complications were com-pared between the two groups. Result Compared with the control group, the operative time was shorter, the in traoperative blood loss was less, the scar size and the postoperative healing time were shorter for the treatment group. The difference had statistical significance (P<0.05).The rate of postoperative pain, local ecchymosis, local infection and breast deformity for the treatment group was significantly lower than those of the control group (P<0.05). The difference had statistical significance (P<0.05). The recurrence rate between the two groups had no sta-tistical significance (P>0.05). Conclusions Single-person operated Mammotome minimally invasive surgery has the advantages of good operative time,good cosmetic effects, small surgical trauma, less blood loss, fast postoper-ative healing and few complications, which is worthy of clinical application.

OBJECTIVE:To compare the clinical efficacy and safety of Kangshuling gel,mupirocin and lactate ethacridine in the treatment of diabetic foot. METHODS:90 patients with diabetic foot were randomly divided into Kangshuling group,mupiro-cin group and lactate ethacridine group. All the patients were treated by lowing blood glucose,nutritional support,improving micro-circulation and anti-infection,etc. On this basis,3 groups were given Kangshuling gel,Mupirocin ointment and Lactate ethacridine solution for wet compress by gauze. The course was 180 d. The clinic data was observed,including clinical efficacy,and wound ar-ea,healed patients’granulation,epithelial tissue,healing time and incidence of adverse reactions before and after treatment. RE-SULTS:The total effective rate in Kangshuling group was significantly higher than mupirocin group and lactate ethacridine group;healed patients’granulation,epithelial tissue and healing time were significantly shorter than mupirocin group and lactate ethacri-dine group,with significant differences(P<0.05). After treatment,wound area in each group were significantly smaller than be-fore,and Kangshuling group was smaller than mupirocin group and lactate ethacridine group,with significant differences(P<0.05);there were no significant differences between mupirocin group and lactate ethacridine group(P>0.05). There were no obvi-ous adverse reactions during treatment. CONCLUSIONS:Based on the conventional treatment,Kangshuling gel has better efficacy than mupirocin and lactate ethacridine in the treatment of diabetic foot,with good safety.

OBJECTIVE:To explore the clinical features and regularity of drug-induced liver injury (DILI),and to provide reference for clinical rational drug use. METHODS:104 DILI cases in our hospital from 2005 to 2014 were selected and analyzed retrospectively in respects of patient’s gender,age,allergic history,medication history,drug type and clinical manifestations. RE-SULTS:DILI hospitalized cases increased year by year. There were 47 males and 57 females,and average age was(8.71±13.90). The clinical symptoms appeared within 12 weeks after using the drug. The symptoms were no specific,including weak,anorexia, jaundice,yellow urine,etc. and 10.57% of patients were asymptomatic. Most of the DILI cases were hepatocyte type(80.77%), followed by cholestasis type(12.50%)and hybrid type(6.73%). The most common cause of drug-induced liver injury were TCM, antimicrobial drugs and the nervous system drugs. CONCLUSIONS:The incidence of DILI in females is slightly higher than males. DILI often occurs after 40 years old. The clinical symptoms have no specificity and are similar to viral hepatitis. The hepatic lesions can be caused by most of drugs. DILI by TCM should concerned. Clinical physicians should pay more attention to DILI.

Objective To investigate the changes and clinical significances of the chemokines of interferon-?-inducible protein-10(IP-10),monocyte chemoattractant protein-1(MCP-1) and growth-related oncogene-?(Gro-?) involved in pathagenesis of Kawasaki disease(KD) and HenochSchonlein purpura(HSP).Methods The chemokines production of IP-10,MCP-1 and Gro-? were assayed by ELISA in 15 patients with KD,12 patients with HSP and 10 healthy children.Results The plasma levels of IP-10 and MCP-1 were markedly elevated in KD group [(394.2?176.4)and(420.5?163.4)ng?L-1]compared with HSP group[(94.8?66.4)and(109.2?76.6)ng?L-1] and the control group [(76.4?46.5)and(87.7?47.8)ng?L-1](all P0.05),as well as Gro-? between the three groups.Conclusion Monocyte may enhance the immune damage in KD pathogenesis,and the levels of IP-10,MCP-1 may be important indexes for KD.Neutrophil may be not involved in pathogenesis of HSP and KD.

This article reports one hepatic echinococcosis patient complicated with systemic sclerosis. His clinical manifesta?tions were the progressive fibrosis of the skin,sour regurgitation,and belching. The blood examination showed that eosinophils was reduced,and antinuclear antibody(ANA)was positive at 1∶100 in cytoplasm particle type. He was given prednisone ace?tate 25 mg,q. d.,aspirin 100 mg,q. d.,centella triterpenes cream 12 mg t. i. d.,esomeprazole 40 mg q. d.,and domperidone 10 mg t. i. d. After one week,the Rodnan skin score reduced from 27 to 17. The liver hydatid cyst resection was performed,and the follow?up showed that his clinical manifestations improved and the Rodnan skin score reduced further.
