Objective To study the expression and significance of matriptase in different metastatic potential of human ovarian cancer cells.Methods High-metastatic human ovarian cancer cell HO8910PM and ovarian cancer cell HO8910 were collected.The ability of metastatic of the former was stronger than that of the latter.Compared the ability of invasion and migration in HO8910PM and HO8910 by scratch assay and by millicell chamber artificial reconstituted basement membrane invasion assay.Detected the matriptase mRNA and protein expression levels in HO8910PM and HO8910 through reverse transcription(RT)-PCR and immunocytochemistry methods.Results The 24 hours' migration distance(347 ± 8) μm of HO8910PM cells were significantly higher than that in HO8910 group (154 ± 10) μm (P ＜ 0.01) ;The number of HO8910PM cells that penetrated the matrigel after 24 hours' incubation were significantly higher than that in HO8910 group (90.7 ±2.1 vs 63.3 ± 1.5,P ＜0.01).The expression of matriptase mRNA in HO8910PM cells was higher than that in HO8910 group (0.72 ± 0.03 vs 0.38 ± 0.04,P ＜ 0.01).The migration was positively correlated with the matriptase mRNA expression levels (r =0.992,P ＜ 0.01); and the invasiveness was also positively correlated with the matriptase mRNA expression levels (r =0.973,P ＜0.01).As far protein level,the expression of matriptase protein in HO8910PM cells was higher than that in HO8910 group (15.6 ±0.8 vs 7.6 ± 1.3,P ＜0.01).The migration was positively correlated with matriptase protein expression levels (r =0.971,P ＜ 0.01) ;And the invasiveness was also positively correlated with the matriptase protein expression levels (r =0.958,P ＜ 0.01).Conclusions The relationship between the expression levels of matriptase and the metastatic of ovarian cancer cells may be correlative.The function of matriptase in ovarian cancer cells metastatic machanism still need to be confirmed.

OBJECTIVE:To observe the clinical efficacy and safety of Xiaozhen zhiyang spray in the treatment of EGFRI-asso-ciated rash. METHODS:A total of 60 malignant tumor patients suffering from rash induced by EGFRI were divided into trial group (40 cases)and control group(20 cases)according to the patient's willingness. Control group didn't received any therapy for rash. Trial group received Xiaozhen zhiyang spray for several times a day according to the degree of rash as 1-2 times/d for first degree, 2-3 times/d for second degree,3-5 times/d for third degree,and the treatment course lasted for 2 weeks. Rash degree and improve-ment,itching degree and improvement,daily life quality index(DLQI)score before and after treatment as well as the occurrence of ADR were compared between 2 groups. RESULTS:before treatment,there was no statistical significance in rash and itching de-gree,or DLQI score between 2 groups(P>0.05). After treatment,rash and itching degree of trial group were improved significant-ly compared to before treatment and control group,with statistical significance(P<0.05). The total response rates of rash and itch-ing therapy in trial group were significantly higher than control group(67.50% vs. 20.00%,70.00% vs. 15.00%),with statistical significance(P<0.05). DLQI score of trial group was significantly lower than before treatment and control group,with statistical significance(P<0.05). There was no statistical significance in DLQI score of control group before and after treatment(P>0.05). No obvious ADR was found in trial group. CONCLUSIONS:Xiaozhen zhiyang spray can effectively relieve EGFRI-associated rash and itching as well as improve the quality of life for patients.

Background and purpose:Antracycline combined with paclitaxel is more widely applied in breast cancer as neoadjuvant chemotherapy.There are differences in applications of different paclita~els.In this research,the efficacy and toxicity of neoadjuvant chemotherapy with ET,ED regimen were compared for the patients with stageⅢbreast cancer.Methods:64 cases of stageⅢbreast cancer patients were divided in two groups.Before surgery,one group had received ET(EPI ivgtt 60 mg/m~2 d_1?21,PTX ivgtt 175 mg/m~2 d_2?21),the other group had received ED(EPI ivgtt 60 mg/m~2 d_2?21,DOC ivgtt 75 mg/m~2 d_2?21)neoadjuvant chemotherapy for three weeks. Curative effect and side effects were evaluated after 2-4 cycles.Results:Total effective rate was 87.5%.Effective rate in ED group was 92.9%,and effective rate in ET group was 83.5%.There was no significant difference(P=0.253).In pCR cases,8 cases in ED group achieved pathologically complete response compared to 3 cases in ET group(P=0.033). The number of patients in ED group(24 cases)hadⅣ-Ⅴgrade pathology evaluation after chemotherapy,it was higher than that in ET patients(21 cases).There was a significant difference(P=0.017).In both groups side effects including hair loss,nausea and vomiting,liver dysfunction were similar.Incidence rate of peripheral neurotoxicity in ET group was higher than that in ED group(P=0.002).Incidence rates of leukopenia,skin rash and phlebitis in ED group were higher than that in ET group.There was a significant difference between two groups in the leukopenia(P=0.034). Conclusions:For the patients with stageⅢbreast cancer patients,both two regimens could achieve better curative effect.ET and ED regimen have similar effect.But in ED regimen,the number ofpCR cases was obviously higher than in ET group.In both groups side effects were similar.There were significant differences in terms of leukopenia and peripheral neurotoxicity,but the side effects could be tolerated.

OBJECTIVETo investigate the effect of siRNA silencing the role of C-Jun N-terminal Kinase (JNK) gene in excessive endoplasmic reticulum stress on lung ischemia/reperfusion injury.

METHODSMouse model of pulmonary ischemia reperfusion injury (PIRI) in situ was established with unilateral lung in vivo. Seventy experimental mice were randomly allocated into seven groups (n = 10): Sham group (Sham group), ischemia reperfusion group (I/R), PBS+ Lipofectamine2000TM transfection reagent group (I/R + PBS+ Lipo group), negative control group (I/R+ SCR group), JNK-siRNA group (I/R + siRNA(JNK1), siRNA(JNK2), siRNA(JNK3)). Mice were euthanized after experimental time out, and left lung tissue was extracted. Wet/dry lung weight ratio (W/D) and total lung water content (TLW) were tested. Light microscope, alveolar damage quantitative evaluation index (IQA) and electron microscope were observed. The expression levels of JNK and glucose regulatex protein(GRP78) were detected by RT-PCR and Western blot. Apoptosis of lung tissue was determined by TUNEL.

RESULTSCompared with Sham group, all indicators above of I/R + PBS + Lipo group and I/R + SCR group were significantly increased (P < 0.01), and compared with I/R group, those indicators of the three groups all had no notable difference; those indicators were not statistically different between I/R + PBS + Lipo group and I/R + SCR group, and compared to the three groups, the above indicators in JNK-siRNA group were lower (P < 0.05, P < 0.01) except that the expression levels of GRP78 was not statistically different.

CONCLUSIONI/R induces excessive ERS in lung tissue, in which JNK pathway participates in apoptosis, leading to lung tissue injury.
