Chinese Journal of Practical Nursing 2017;33(7):508-512
Objective To describe self-care agency and its influence factors of the patients with temporary ileum stoma. Methods The descriptive statistics of non-experimental study was performed in the study. The convenience sample consisted of 144 patients from 3 hospitals in Shanghai. The self-care agency was measured by the Colostomy Self-care Agency Scale. Results 144 cases of colorectal cancer temporary ileum stoma patients′ self-care ability scored an average of 57.02 ± 7.00, including self- care willingness (37.19 ± 4.04) points, self-care knowledge 17 points, self-care skills 3 points. The multiple stepwise regression analysis showed that seven factors were statistically significant including age, gender, culture level, living area, postoperative months, presence of complications, whether to accept professional nursing training or education. Conclusions Temporary ileum stoma in patients of rectal cancer with medium self-care ability, but self-care skill level is relatively not high and should be strengthen attention in patients with rectal cancer undergoing ileum stoma. Targeted nursing intervention should be carried out to improve the self-care ability and improve the quality of life of patients with stoma.

OBJECTIVE:
To study the influence of PD173074 on proliferation and apoptosis of nasopharyngeal carcinoma.
METHOD:
With immunoblotting and RT-PCR, FGFR1 expression was detected in CNE, PONE1 and C666-1 cell lines. With MTT assay,the time-effect and dose-effect correlation between PD173074 and inhibition of CNE proliferation was evaluated. After PD173074 stimulation, the phosphorylation level of FGFR1 and AKT was detected with immunoblotting assay. Furthermore, influence of PD173074 on the activation of Caspase3 and Caspase9 was detected to study the underlying mechanism of why PD173074 could inhibit CNE proliferation.
RESULT:
FGFR1 has the highest expression in CNE cell line. Under incubation of 10 nmol/L PD173074 stimulation for 36 hours to 72 hours, the phosphorylation of FGFR1 and AKT was impaired significantly, which further reduced the proliferation of CNE. Moreover, PD173074 can activate the intrinsic apoptotic pathway by stimulating Caspase9,which activated Caspase3 and induced the apoptosis.
CONCLUSION
PD173074 could inhibit proliferation of nasopharyngeal carcinoma cell through reducing the phosphorylation of FGFR1 and AKT. Additionally, PD173074 can induce CNE apoptosis by activating intrinsic apoptotic pathway via cleaving Caspase9 and Caspase3.

Objective To study the effect of Gabapentin(GBP)on the transient receptor potential vanilloid l(TRPV1)in dorsal root ganglion (DRG)of rats with chronic constriction injury(CCI). Methods SD male rats were used to establish CCI model and randomly divided into 3 groups,the control group,the CCI group,and the CCI+GBP group. Mechanical allodynia and thermal hyperalgesia were measured to evaluate the es?tablishment of CCI model and the analgesic effect of GBP. At the postoperative 8 days,all rats were sacrificed and dorsal root ganglions were collect?ed for further RT?PCR and Western?blotting analysis to detect expression of TRVP1 in DRG. Results The mRNA and protein expression of TRPV1 were both significantly increased in DRG after CCI operation and GBP could decrease mRNA expression of TRPV1 gene in DRG after CCI. Conclusion The expression of TRPV1 was increased in DRG after CCI operation which was decreased after administration of GBP.

AIM To develop a sensitive and specific LC/MS/MS method for determination of amlodipine in human plasma. METHODS Amlodipine and internal standard 4′-hydroxypropafenone were extracted from plasma using liquid-liquid extraction, then separated on a Zorbax C8 column. The mobile phase consisted of acetonitrile-water-formic acid (75∶35∶1), at a flow-rate of 0.4 mL*min-1. A Finnigan TSQ tandem mass spectrometer equipped with electrospray ionization source was used as detector and was operated in the positive ion mode. Selected reaction monitoring (SRM) using the precursor → product ion combinations of m/z 409 → 238 and m/z 358 → 116 was used to quantify amlodipine and internal standard, respectively. RESULTS The linear calibration curves were obtained in the concentration range of 0.4-16.0 ng*mL-1. The limit of quantification was 0.4 ng*mL-1. Each plasma sample was chromatographed within 3.7 min. The method was successfully used in several pharmacokinetic studies for amlodipine. More than 1 500 plasma samples were assayed within two weeks. CONCLUSION The method is proved to be suitable for clinical investigation of amlodipine pharmacokinetics, which offers advantages of specificity, speed, and greater sensitivity over the previously reported methods.
