Objective To discuss the influence of nursing intervention on sleep quality and postoperative comfort of patients with percutaneous coronary intervention(PCI). Methods We divided 96 patients who were to receive PCI into the test group and control group with 48 patients in each group.The control group received routine nursing while the test group were given systemic nursing intervention based on routine nursing intervention.The sleep quality and incidence rate of complications were compared. Results The sleep quality in the test group was better than that of the control group (P ＜ 0.01 ).The ineidience of waist-back pain,dysuria,induced emiction,eatheter emietion,anaesthesia of lower limbs,fidget in the test group also decreased compared with the control group(P ＜ 0.05). Conclusions Systemic nursing intervention could improve the sleep quality and postoperative comfort for PCI patients

Conclusion The implementation of nursing safety management for indwelling catheters can ensure medical and nursing safety,and promote the continuous improvement of quality of nursing.

Objective To establish the HPLC fingerprint of amino acids compounds from Buzhong Yiqi Pill.Methods A pre-column derivatization HPLC method was adopted with praline as a reference.Separation was performed on a AccQ? TagTM C18(3.9? 150 mm)analytical column with mobile phase consisting of 0.15 mol/L sodium acetate buffer solution and 60 % acetonitrile,gradient elution with the flow rate of 1.0 mL/min.The column temperature was at 37 ℃.The Fluorescence detecting wavelength was set at 250 nm(excitation wavelength)and 395 nm(emission wavelength),the analysis time was 35 min.Results Twelve common peaks on the HPLC fingerprints of Buzhong Yiqi Pill were presented.The similarity was determined by the correlation coefficient,included angle cosine coefficient and evaluation software of chromatogram fingerprint similarity.The results showed the similarity for 10 bathes of samples was in 0.97～ 1.00.Conclusion Good fingerprints were obtained,which can be used for the quality control of Buzhong Yiqi Pill.

Objective To establish the fingerprint chromatogram of Buzhong Yiqi Decoction(BYD) by multiple wavelength method,and to analyze the substance of formulas as a whole.Methods HPLC-PDA method was adopted.The chromatographic conditions were as follows:Hypersil ODS2 analytical column,the mobile phase consisting of 0.05 %phosphate acid and acetonitrile with gradient elution,detecting wavelength at 254 and 280 nm,the flow rate being 1.0 mL/min and the temperature of the column at 30 ℃.Results The methodological results were good.The results of dual-wavelength fingerprint chromatogram showed the all-around information of the fingerprints at 254 and 280 nm.The similarity of 10 batches of BuzhongYiqi Decoction was over 0.98.Conclusion Dual-wavelength fingerprint chromatogram can realize the analysis of a formulas as a whole,which supplies references for improving the quality control of BuzhongYiqi Decoction.

Objective To study the change of matrix metalloproteinase-2 (MMP-2) in the development of renal fibrosis and evaluate the diagnostic value of blood MMP-2 level in renal fibrosis.Methods Thirty three patients with chronic glomerulonephritis were divided into proliferation group(n=18) and fibrosis group(n=15) according to renal fibrosis degree in renal pathology.Another 8 healthy subjects were used as control group.The levels of pro-MMP-2 and MMP-2 in serum were measured with the method of SDS-PAGE enzymography.Then the levels of pro-MMP-2 and MMP-2 in serum were compared between various groups.Results The serum MMP-2 level in proliferation group was much higher than that in control group(P0.05).Conclusion There is a significant difference of serum MMP-2 between suffering group and normal control group.Therefore the detection of serum MMP-2 level can be conducive to understand the development of disease and estimate prognosis.

Objective To explore the MRI findings of ovarian cancer peritoneal carcinomatosis (PC).Methods MRI findings of 34 cases with advanced ovarian cancer and PC confirmed by operation and pathology were reviewed retrospectively.MRI protocols included T1 WI,T2 WI,MRH,DWIBS,and gadolinium-enhanced 3D THRIVE sequences.The type of ovarian tumor and MRI manifestations of PC were analyzed.Results All of the ovarian tumors and PC lesions were high signal intensity in DWIBS.All of the ovarian tumors were shown as mixed cystic solid masses,including type Ⅱa in 12 cases,type Ⅱb in 7 cases,and type Ⅱc in 1 5 cases.The MR manifestations of PC were described as follow:linear thickening of the peritoneum (n=2),irregular linear thickening of the peritoneum (n=27);smudged thickening of the omentum (n=1 9),cake-like thickening of the omentum (n=1 1);fouling-appearance of the mesentery (n=4);plaque,nodule and mass in the abdominal cavity (n= 34),cystic mass (n=8).PC lesions were detected in the Douglas’space in 31 cases,paravesical interspace in 24 cases,omentum in 20 cases,paracolic gutter in 9 cases, right subdiaphragmatic / parahepatic space in 1 1 cases,and left subdiaphragmatic / parasplenic space in 10 cases.The primary and PC tumors invaded the rectum in 26 cases,sigmoid in 22 cases,and uterus in 1 6 cases.Ascites and lymphadenectasis in abdomen were seen in 33 and 7 cases,respectively.Conclusion Ovarian cancer PC can be diagnosed accurately by combing DWIBS and con-ventional MRI.

Symptomatology and medical history taking are the focuses of diagnostics study. With the improvement of teaching and learning, students can basically master the standard process of clinical inquiry of chief complaints to family history efficiently. However, due to the lack of systematic learning of clinical diseases, it's difficult for most students to form a targeted, logical and speculative inquiry thinking pattern, so they are unlikely to write a medical history of present illness that reflects their thinking on disease inclusion and exclusion. In this study, we come up with the characteristics and defects of symptomatology teaching at present, and put forward a new idea of symptomatology teaching by introducing clinical manifestations of diseases and examples of inquiry.

Purpose To explore the clinical value of ultrasound in charactering brain anomalies in open spina bifida at 11-13+6 weeks of gestation.Materials and Methods Abdominal and transvaginal ultrasound was performed in 125 cases of normal fetus and 4 cases of confirmed open spina bifida at 11-13+6 weeks of gestation to compare the morphology of intracranial translucency (IT), diencephalon and midbrain.Results Fetal IT was readily recognized in all 125 normal cases, with diencephalons and midbrain showing number 8 shape. In 4 cases of open spina bifida, fetal IT cannot be identified, and the expected 8 shape of diencephalon and midbrain was distorted.Conclusion Fetal brain characteristics including intracranial translucency and the shape of diencephalon and midbrain in 11-13+6 weeks gestation are valuable ultrasound screening indicators for open spina bifida.

Objective To observe the effect of electroacupuncture on onset time and effectiveness of Paroxetine for mild or moderate depression patients and on the scores of Hamilton depression rating scale for depression(HAMD) and self-rating depression scale(SDS). Methods Fifty-five patients with mild or moderate depression were randomly divided into A group( Paroxetine group,29 patients) and B group (Electroacupuncture combining with Paroxetine group,26 patients). Therapeutic periods for the two groups were 6 weeks. HAMD and SDS were used to evaluate the efficacy before the research and after treatment on 1 week,2 weeks,4 weeks,6 weeks.Results HAMD scores and SDS scores for A group were significant difference after 2 weeks treatment compared with the beginning of the research (P＜ 0.05 ) ;HAMD scores and SDS scores for B group were significant difference after 1 week treatment compared with the beginning of the research(P＜0. 05 ). Total effective rate of HAMD for A group was 71.4% ,total effective rate of SDS for A group was 75% ,total effective rate of HAMD for B group was 88% ,total effective rate of SDS for B group was 84%. The total effective rate between the two groups ordered by the individual chi-square test was significant difference( X2 = 4. 1790, P= 0. 0408). Conclusion Electroacupuncture can shorten the onset time and increase the effectiveness of paroxetine for mild or moderate depression patients.
