Colonic neoplasms is the third most commonly diagnosed cancer in men and second most commonlv diagnosed cancer in women worldwide.The morbidity of Colonic neoplasms is increasing year by year.Despite the fact that surgery is still the main treatment for patients with colon cancer,surgery alone hasn't improved the treatment effectiveness.The current management of colon cancer has come to multidisciplinary team (MDT) modality.MDT modality could offer the optimal treatment option and the internal communication.Under the pattern of MDT which integrates the surgery,chemotherapy,radiotherapy,interventional therapy,targeted therapy and immune therapy,there has been a big progress in the diagnosis and treatment of colon cancer.Patients with metastatic colon cancer should undergo a discussion by a multidisciplinary team before the initial treatment.

Objective To summarize our experiences in the long-term continuous maintenance of the peripherally inserted central catheter (PICC) in a patient with intestinal fistula.Method The systematic holistic nursing care has been provided according to the nursing practices to a patient with intestinal fistula since 2006,during which eitht PICCs were used successively.Results The eight PICCs were placed for 3-14 months.The 1 st,3rd,5th,and 7th cathers were retained for 12,13,11,and 14 months.The second catheter was retained for 6 months,and then removed due to increased body temperature (38.7℃).The 4th cather was retained for 3 months,then catheter-related bloodstream infection was suspected due to high body temperature (39℃) ; culture for fungi at the tip showed positive results.The 6th catheter was retained for 7 months,inserting from jugular vein to the superior vena cava; however,it was removed due to puncture point local purulent changes at the puncture site.The 8th catheter was applied for 8 months,but was rmoved due to tube occlusion,which responded poorly to urokinase.Conclusion The application of PICC in patients with fistula can relieve the pain and improve the quality of life.

Objective To understand the actual psychological conditions of pregnant patients with gynecologic malignancies during chemotherapy so as to instruct the nurses to provide individualized psychological care to the patients and their relatives. Method The in-depth interviews were conducted to 7 patients by implementing the phenomenological approach of qualitative study. The acquired data were analyzed. Result The patients experienced four psychological conditions: pessimism about prognosis, anxiety to know more about the chemotherapy and guilty to their family and hope for treatment effect. Conclusion Nurses should pay attention to the psychological conditions of pregnant patients with gynecologic malignancies and help them successfully live through the treatment.

OBJECTIVE:To establish a method of determining the plasma concentration of capecitabine/polyethylene glycol 1000/montmorillonite (CAP/PEG1000/MMT) in rats’plasma for the study on pharmacokinetics of CAP compound in rats in vivo. METHODS:HPLC was adopted. The determination was performed on Kromasil C18 with mobile phase consisted of 0.1% glacial acetic acid-acetonitrile(73∶27),at the flow rate of 1.0 ml/min. The detection wavelength was 250 nm and column temperature was 40 ℃. The sample size was 10 μl. 18 Wistar rats were randomly divided into CAP group,CAP/MMT group(MMT as carrier)and CAP/PEG1000/MMT group(PEG1000/MMT as carrier)and ig given corresponding drugs,that equal to 200 mg/kg of CAP. Blood sample was respectively taken 15,30,60,90,120,180,240,300 and 360 min after the administration of drugs,and plasma was isolated and added with internal standard ferulic acid. The concentration of the drug in the plasma was determined by HPLC fol-lowing protein precipitation with methanol,based on which the pharmacokinetic parameters were calculated by 3p97 software. RE-SULTS:The linear range of CAP was 0.054 9-4.390 0 μg/ml (r=0.998 2) with the method recovery of 98.2%-102.1%(RSD=1.50%-3.29%, n=5) and absolute recovery of 76.2%-78.9%(RSD=2.29%-2.99%, n=5). In the above-mentioned three groups,t1/2 were(1.11±0.32),(1.57±0.32)and(1.62±0.10)h;cmax were(2.91±0.36),(0.91±0.23)and(0.91±0.14)μg/ml;AUC0-6 h were (8.70 ± 1.79),(3.76 ± 0.27) and (3.73 ± 0.25)μg·h/ml;and tmax were (0.97 ± 0.20),(1.55 ± 0.47) and (1.50 ± 0.07) h,respectively. There was no significant difference in the pharmacokinetic parameters between the CAP/MMT group and CAP/PEG1000/MMT group(P>0.05). CONCLUSIONS:The method is reliable and simple,and can be used for pharmacokinetic study of CAP/PEG1000/MMT in rats. MMT and PEG1000/MMT compound can prolong CAP acting time in the body.

OBJECTIVE:To explore the method for promoting drug circulation management of online pharmacies. METH-ODS:Hazard analysis and critical control point (HACCP) was applied to identify the critical control points (CCPs) and explore the effective method for drug circulation management of online pharmacies. RESULTS & CONCLUSIONS:According to the HAC-CP principle,four CCPs of drug circulation management of online pharmacies are supplier qualification,acceptance method,main-tenance and storage scheme and distribution system. It is suggested to adopt correct measures of drug circulation quality manage-ment of online pharmacy. Firstly,the supplier’s legal qualification should be determined and the quality of the drug should be regu-larly checked;secondly,drug retailers should improve the acceptance method of drugs and improve the sampling rate of drug;then,the three three four scientific conservation which required the medicine to be divided into three parts according to the pro-portion of 30%,30%,40% and checked monthly should be implemented to improve the storage and maintenance program;finally, the independent distribution system should be established to ensure the full process of the appearance inspection.

Background and purpose:Inhibitor of apoptosis-stimulating protein of p53 (iASPP) is one of the ASPP family. It binds to p53 to inhibit the transcriptional activity of p53-target genes and cell apoptosis, which is asso-ciated with tumor formation. Previously, we found a new subtype of iASPP, iASPP splice variant (iASPP-SV), which is a nuclear protein containing 407 amino acid residues and can bind to p53, inhibiting p53 transcriptional activity. However, the relationship of iASPP-SV and breast cancer is still obscure. Therefore, the purpose of this research was to study the role of iASPP-SV on breast cancer tumorigenesis and progression.Methods:5’-rapid ampliifcation of cDNA ends (RACE) was used to identify the 5’-end of iASPP-SV mRNA in MCF-7 cells. HEK 293 cells were transfected with pFLAG-iASPP-SV and pFLAG-iASPP (828). Then Western blot was used to identify whether endogenous iASPP-SV was expressed in HEK 293 cells and 8 types of human tumor cell lines. This study established the stable clones of NIH 3T3 expressing FLAG-iASPP-SV and FLAG-iASPP (828). Cell proliferation assay, colony formation and soft agar colony formation assay were used to identify whether iASPP-SV and iASPP (828) can promote cell proliferation and iASPP-SV is an oncogene. Real-time lfuorescent quantitative polymerase chain reactive (RTFQ-PCR) was used to de-tect the levels of iASPP-SV and iASPP (828) mRNA in primary breast cancers. Luciferase assays were used to identify the relationships between iASPP-SV, iASPP (828), p53 and NF-κB p65.Results:The study identiifed that iASPP-SV was encoded by previously reported NF-κB p65 subunit (RelA)-associated inhibitor (RAI), and endogenously expressed in many human cancer cell lines. Analysis of cell proliferation, colony formation assay and soft agar assay for colony formation identiifed that similarly to iASPP (828), iASPP-SV promoted tumor cell proliferation and acted as an onco-gene. RTFQ-PCR result showed that the median values of iASPP-SV and iASPP (828) in breast cancers with wild-type p53 were more signiifcantly over-expressed than those of mutant p53. Luciferase assays showed that iASPP-SV and iASPP (828) could suppress NF-κB p65 transcriptional activity. Thus iASPP family may participate in the regulation of p53 and NF-κB activity, which imply that iASPP perhaps shows pro- or anti-survival activities when it interacts with different proteins.Conclusion:These ifndings indicate that iASPP-SV may be a potential target for breast cancer thera-py.

Objective To evaluate the effects of dexmedetomidine on action potential in isolated rabbit sinoatrial node cells.Methods Twenty-four healthy New Zealand rabbits of both sexes,weighing 1.5-2.5 kg,were sacrificed.Their hearts were removed and sinoatrial nodes were dissected and placed in Tyrode solution.Sixty isolated sinoatrial nodes were randomly divided into 6 groups (n =10 each):control group (group C),0.5 ng/ml dexmedetomedine group (group D1),5.0 ng/ml dexmedetomedine group (group D2),dexmedetomidine 5.0 ng/ml + yohimbine 1 μmol/L (alpha 2-adrenoreceptor antagonist) group (group D2 + Y),dexmedetomidine 5.0 ng/ml + 2 mmol/L CsCl (blocker of pacemaker current) group (group D2 + C),and dexmedetomidine 50.0 ng/ml group (group D3).After perfusion with the Tyrode' s solution for 60 min,C group was perfused with Tyrode' s solution for another 40 min,D1-3 groups were perfused with Tyrode's solution cont(a)ining dexmedetomedine 0.5,5.0 and 50.0 ng/ml,respectively,for40 min,and D2 + Y and D2 + C groups were perfused with Tyrode' s solution containing 1 μmol/L yohimbine and 2 mmol/L CsCl,respectively,for 20 min,and then 5.0 ng/ml dexmedetomedine was added and sinoatrial nodes were perfused for 20 min.Maximal rate of depolarization (Vmax),amplitude of action potential (APA),action potential duration at 50％ and 90％ repolarization (APDso and APD90),velocity of diastolic (phase 4) depolarization (VDD),and rate of pacemaker firing (RPF) were recorded at 60 min of perfusion with Tyrode' s solution (T1),20 min of perfusion with yohimbine or CsCl (T2) and termination of perfusion with dexmedetomedine (T3).Results Compared with group C,APA,VDD and RPF were gradually decreased at T2,3 in groups D1-3 (P ＜ 0.05),and there was no significant difference in Vmax,APD50 and APD9o among C and D1-3 groups (P ＞ 0.05).VDD and RPF at T2 in group D2 + C and APA,VDD and RPF at T3 in groups D2 + Y and D2 + C were significantly lower than those at T1 (P ＜ 0.05).APA,VDD and RPF in group D2 + Y and APA in group D2 + C were significantly lower at T3 than at T2 (P ＜ 0.05).Conclusion Dexmedetomidine can decrease the sinoatrial node autorhythmicity in a concentration-dependent manner in rabbits,and the mechanism may be related to the inhibition of pacemaker current,but not alpha 2-adrenoreceptor.

Objective To evaluate the effects of real-time continuous glucose monitoring (RT-CGM) system on oxidative stress and mortality in critically ill patients and to explore the correlation between glucose index,oxidative stress and mortality.Methods Selected 123 cases of critically ill patients were enrolled in this prospective randomized controlled study.They were randomly divided into the RT-CGM group(n =61) and blood glucose meter group (GM group,n =62).The following parameters were compared between the two groups:mean amplitude of glucose excursions (MAGE),hypoglycemia incidence,low blood glucose index (LBGI),high blood glucose index (HBGI),28-day mortality and plasma level of 8-iso-PGF2α (8-iso) at 48 hours (R2),72 hours (R3) and 96 hours(R4) after admission to ICU.The correlation between glucose index and plasma level of 8-iso-PGF2α were analyzed.The correlation between glucose index,plasma 8-iso level and 28-day death were analyzed.Results The parameters of MAGE,hypoglycemia incidence,LBGI and HBG1 in the RT-CGM group and the GM group were (3.73 ±1.09) mmol/Land (4.19±1.11)mmol/L(P=0.02),3.28％ and 14.52％(P=0.03),0.0011 and 0.0119 (P ＜ 0.01) and 0.2258 and 0.3697 (P ＜ 0.01),respectively.The plasma levels of 8-iso at R2,R3,R4 in the RT-CGM group and the GM group were (111.44 ± 16.99) ng/L and (114.03 ± 14.64) ng/L(P=0.37),(94.53 ±14.92)ng/L and (110.31 ±13.42) ng/L(P＜0.01) and (57.84±12.22) ng/L and (84.41 ± 14.16)ng/L(P ＜0.01),respectively.The r values between MAGE,LBGI,HBGI and the plasma level of 8-iso were 0.69,0.71 and 0.67,respectively (all P values ＜ 0.01).Multivariate stepwise regression analysis showed MAGE,LBGI,HBGI entered final models (corrected R2 =0.61,P ＜ 0.01) with β values of 0.64,0.65 and 0.6 respectively(all P values ＜0.01).The 28-day mortality in the RT-CGM group and the GM group was 9.84％ and 30.65％ (P ＜0.01).The OR values of MAGE,hypoglycemia incidence,LBGI,HBGI and the plasma level of 8-iso for 28-day death were 2.14 (0.98-4.35),3.43 (1.12-5.82),2.67 (1.01-5.14),1.32 (0.24-2.96) and 1.89 (0.67-3.44),respectively.Conclusion RT-CGM can optimize the care in critically ill patients by improving hypoglycemia,hyperglycemia,glucose variability and oxidative stress and bring more detailed concern in the process,and to reduce the mortality.

Objective:This study aimed to investigate the associations between single-nucleotide polymorphism (SNP) of IGF-1 and IGFBP-3 gene and risk of non-smoking female lung cancer in Chinese population. Methods:Genotyping was performed using the TaqMan method in 287 histologically confirmed non-smoking female lung cancer cases and 281 healthy controls. Results:The geno-type distributions of IGF-1 polymorphisms were significantly different between cases and controls (P<0.001). Analysis of multivariate logistic regression showed that the carriers of the CC genotype exhibited a significantly decreased risk of lung cancer in non-smoking female (adjusted OR=0.28, 95%CI:0.15-0.54). IGF-1 rs1520220 GG genotype may reduce the risk of advanced lung cancer incidence in nonsmoking female (adjusted OR=0.30, 95%CI:0.09-0.96). Log-rank test and Cox regression analyses revealed that variant geno-types of IGF-1 rs2946834 CT/TT had a significantly decreased lung cancer mortality risk compared with the homozygote CC in≥60 age group or patients with a lung tumor>3 cm. Conclusion:The IGF-1 polymorphism was associated with the risk of lung cancer and prognosis among non-smoking female. More rigorous laboratory studies of large sample population and functional studies are warrant-ed to confirm our findings.
