ABSTRACT
Objective To establish a scientific and reasonable evaluation index system of nursing quality for cystoscopy. Methods After 2 rounds of Delphi survey technique, get the consensus of the evaluation indicators of the initial evaluation of the 18 experts,and ultimately build a system for nursing quality evaluation index during cystoscopy. Results After 2 rounds of expert consultation, the evaluation index system based on the three level structure of the medical quality framework includes:3 first-level indicators,8 second-level indicators,33 third-level indicators. Conclusions The evaluation index system established in this study is helpful to standardize the nursing behaviors of nurses in the examination process,improve the quality of nursing service in the process of cystoscopy, and improve the accuracy and reliability of inspection.
ABSTRACT
Objective To establish a quality indicator system of nursing services for patients with urodynamics. Methods Delphi method was used in the study, and the quality indicator system of nursing services for patients was based on two rounds of consultation among 16 experts. Results The quality indicator system of nursing services for patients with urodynamics consisted of 3 first-level indicators, 8 second-level indicators and 29 third-level indicators. Experts had the same opinions on the indicators. Conclusions Nursing behavior for patients with urodynamics could be standardized based on the quality indicator system, and therefore guide nursing work and improve nursing quality. Further theoretical and empirical study is needed to verify the quality indicator system.
ABSTRACT
To investigate the clinical applications of robot-assisted radical cystectomy with orthotopic ileal neobladder [RARC-INB] and make a preliminary summary. Retrospective analysis the clinical data of 12 patients underwent robotic bladder cancer [da vinci surgical system] assisted laparoscopic cystectomy with ileal orthotopic neobladder from March 2015 to April 2015. 12 cases were successful, with no surgical intervention, and organ damage occurred. The operation time was 330470 min, which average [390.0 +/- 61.5] min; blood loss was 90870 ml, which average [185.0 +/- 88.3] ml. One case of intraoperative blood transfusion was 400 ml. The enjoin eating time of postoperative intestinal ventilation was 36 d, and the average time was [4.0 +/- 1.5] d. Removal of ureteral stents time was 1428 d and the average time was [21 +/- 7] d. Removal of the catheter time was 1828 d and the average time was [23 +/- 5] d. Postoperative hospital stay 1929 d and the average time was [24 +/- 5] dRARC-INB make the surgical tends to simplify, which was conducive to surgeon intraoperative control and assurance. RARC-INB make the surgical tends to use less trauma, less bleeding, complete lymphadenectomy, quick recovery, etc. It is a safe, effective and reliablethe method in the treatment of invasive bladder cancer. So the method should be widely applied

<p><b>OBJECTIVE</b>The non-specific antitumor immunity effect of 4-1BBL-B7-H3 gene was investigated by establishing an oral squamous cell carcinoma human peripheral blood lymphocyte-severe combined immunodeficient (SCID) mice chimeric model.</p><p><b>METHODS</b>Forty mice were randomly divided into five groups. All groups, except the non-immune reconstitution group (group D), had reconstructed human partial immune system. The control group (group A) was injected with Tca8113 cells. The Ad4-1BBL-B7-H3 group (group B) was injected with Tca8113 cells transfected by adenovirus containing 4-1BBL-B7-H3 gene. The empty vector group (group C) was injected with Tca8113 cells transfected by adenovirus containing an empty vector. The non-immune reconstitution group (group D) was injected with Tca8113 cells. The non-tumor group (group E) was injected with PBS. The tumor volumes in each group were measured weekly. Human IgG in blood was obtained through the tail vein and was determined by enzyme-linked immunosorbent assay. Human CD3+ and D56 lymphocytes were assessed by flow cytometry. Model animals were killed on the ninth week. Differences in the expression of the natural killer group 2 member D (NKG2D) and toll-like receptor 2 (TLR2) in tumor tissues of each group were observed by immunohistochemical method. 4-1BBL-B7-H3 gene expression in mice tumor tissues was detected by reverse transcription polymerase chain reaction (PCR) and the expressions of major histocompatibility complex 1 class related molecule (M1C) A, M1CB, and TLR2 were detected by real-time quantitative PCR.</p><p><b>RESULTS</b>The tumor volumes of group B were remarkably lower than those in the other groups (P < 0.05). Human IgG and CD3+ and CD56+ lymphocytes were detected in the peripheral blood of immune-reconstituted mice. These lymphocytes were remarkably higher in group B than those in groups A, C, and E (P < 0.05). Higher NKG2D and TLR2 expression were observed in group B tumor than those in the other groups. The stable expression of 4-1BBL-B7-H3 gene in group B was proven. The expression of M1CA, M1CB, and TLR2 were significantly higher in the group B tumor than those in groups A, C, and D (P < 0.05).</p><p><b>CONCLUSION</b>The high 4-1BBL-B7-H3 gene expression in tumor tissues could successfully induce the proliferation of CD3+ and CD56+ lymphocytes. This expression can also directly or indirectly activate TLR2 and up-regulate the expression of NKG2D and its ligands (M1CA and M1CB), which result in an effective antitumor immune response.</p>

Objective:To explore the effects of NOD2 gene on the proliferation and apoptosis of tongue squamous cell carcinoma Tca8113 cells.Methods:NOD2 expression vector(NOD2-pEZ-M29)and NOD2-shRNA vector were established,then were trans-fected into Tca8113 cells respectively.Expressions of HBD-2 and NOD2 in the cells was detected by RT-PCR and Western blot.Cell proliferation was examined by MTT assay and apoptosis by flow cytometry at 48h post transfection.Results:Compared with the control group,the expression of NOD2 and HBD-2 in NOD2-pEZ-M29 transfection group was significantly higher and markedly lower in NOD2-shRNA group.The proliferation rate of Tca8113 cells was markedly lower in NOD2-pEZ-M29 transfection group and signifi-cantly higher in NOD2-shRNA group while the apoptosis rate was significantly higher in NOD2-pEZ-M29 transfection group and sig-nificantly lower in NOD2-shRNA group.Conclusion:In Tca8113 cells NOD2 expression was positively correlated with HBD-2 ex-pression.NOD2 gene may promote the apoptosis,inhibit the proliferation of Tca8113 cells.
ABSTRACT
A new method was established for the direct, rapid and quantitative analysis of pesticide residues, dimethoate chlorothalonil and malathion by low temperature plasma ( LTP) ionization miniature ion trap mass spectrometer. The LTP ionization probe and sample inlet of ion trap mass spectrometry were enclosed in a metal cavity. With non-contact heating, the samples placed on the sample platform were desorbed into gaseous phase and ionized by LTP ionization probe. The results showed that closed ionization had an edge over the opened ionization. The quantitative analysis of 3 pesticides within the range of 0. 5-10 mg/L was realized by optimizing heating time and flow rate of air, and the relative standard deviations of signal intensity is less than 11%. LODs of pesticide, which were obtained within 5 s, were as low as several hundred pictograms. The results showed that the method could be used for the analysis of pesticide residue on green and organic fruits or vegetables.
