China Medical Equipment 2017;14(2):70-73
Objective:To compare the efficacy and complication in clinical application about the indwelling central venous transfusion port and peripheral venipuncture central vein indwelling catheter.Methods: 80 cases with indwelling central vein transfusion port were arranged to observation group and 80 cases with peripheral venipuncture central vein indwelling catheter were arranged to control group. All of patients were detected for blood routine, blood coagulation time and chest X-ray fluoroscopy routine examination before operation. And to take venipuncture by right subclavicle of patient skin under X-ray fluoroscopy guided, and then indwell catheter. To compare the clinical effect for the two kinds of indwelling catheter method.Results:In observation group, the successful rate was 97.5% (78/80), the average operation time was (51.23±10.21) min; while in control, the successful rate was 78.8% (63/80), the average operation time was (67.42±11.03)min, there were statistical significant difference in successful rate (x2=13.44,P<0.05) and average operation time (t=9.63,P<0.05) between observation and control group. In observation group, the rate of complications occurred was 13.75% (11/80), which was significant lower than 32.5% of control (26/80)(x2=7.91,P<0.05).Conclusion: It is safe and reliable to use the dwelling central venous transfusion port, and the complication of some patients mainly related with nursing skill of paramedic and the proficiency degree of pillbox puncture and using skill in this operation.
2.Polyhydroxyalkanoate polymer carrying chondrocytes for repair of allogeneic laryngeal cartilage defects
Chinese Journal of Tissue Engineering Research 2015;(38):6140-6144
BACKGROUND:Laryngeal cartilage defect has a higher incidence, mainly presenting with pain, sweling, and dysfunction after onset. Currently, surgical treatment is the most used in clinical treatment of laryngeal cartilage defect. Although conventional materials can effectively improve symptoms, there is a poor long-term efficacy. In recent years, there are many clinical studies on cartilage tissue engineering, but less about the actual use in the otorhinolaryngology department.
OBJECTIVE:To investigate the effect of polyhydroxyalkanoate polymer carrying chondrocytes on the repair of alogeneic laryngeal cartilage defects.
METHODS:Poly(3-hydroxybutyrate-co-3-hydroxyhexanoate) (PHBHH) served as the extracelular matrix. Tissue engineering technology was used to prepare cel-material composite. Primary tissue-engineered cartilage tissue was transplanted directly into rabbit thyroid cartilage defect (experimental group A), or implanted into a more mature tissue-engineered cartilage for the repair of thyroid cartilage defect (experimental group B). In the experiment, PHBHH group and simple chondrocyte group were set as controls. Repairing effects on thyroid cartilage defect were evaluated through gross and histological observation.
RESULTS AND CONCLUSION:Chondrocytes in the primary tissue-engineered cartilage tissues were beaded under scanning electron microscope, and after 4 weeks of culture, a large amount of jely-shaped substrates were visible. Findings from electron microscope observation showed that the cels were distributed on the surface of composite material and cavernous voids, displaying a plurality of smal round projections. Surgical treatment was successful in al the rabbits, and there was no dyspnea and eating difficulties after surgery. One rabbit appeared to have brief wheezing in the experimental group A, two rabbits died of diarrhea in the experimental B group at 2 weeks after surgery. PHBHH composite carrying chondrocytes had certain hardness. At 4 weeks after subcutaneous implantation, mature cels were shaped as white sheets, and the material had elasticity. After 4 and 8 weeks, the space between repair zone and original cartilage tissue was smooth and plain, but the repair zone was colored yelow. In the simple PHBHH and chondrocyte groups, the repair zones were both depressed, only the connective tissues could be seen. Rabbits in the two experimental groups showed less adverse reactions compared with the two control groups (P < 0.05). These findings indicate that PHBHH composite carrying chondrocytes has better effects to repair alogeneic laryngeal cartilage defects.
3.Establishment of in vitro and cell-based drug screening model for Notch signaling pathway.
Acta Pharmaceutica Sinica 2014;49(6):837-42
Notch signal pathway is closely related to the organism's development and a variety of cancers. Current models available for screening modulators of Notch signal pathway all use mouse Notch protein as substrates and those models which use human Notch protein have not been reported. To make the screen results much more reliable, the authors cloned a truncated form of human Notch1 called N100, and built the screening models for the use of it instead of mouse Notch protein. The models included an in vitro screening model based on the purified gamma-secretase enzyme and a cell model using luciferase reporter system. The screening models then have been verified by the known modulators of Notch signal pathway and the IC50 values have been obtained. The verified models can be used to screen modulators of human Notch signaling pathway effectively and it can lay the foundation for finding new modulators of this kind effectively.
4.Exploration of clinical value of colposcopy directed biopsy in diagnosis of vaginal intraepithelial neoplasia
Chinese Journal of Postgraduates of Medicine 2013;36(33):1-4
Objective To explore the clinical value of colposcopy directed biopsy in diagnosis of vaginal intraepitheal neoplasia (VaIN).Methods The clinical data of 106 VaIN patients diagnosed by colposcopy directed biopsy were reviewed and analyzed retrospectively.In the past medical history of 106 patients,46 patients had cervical cancer history,43 patients had cervical intraepithehal neoplasia history,13 patients had previous hysterectomy because of benign disease and 4 patients had uncertain past medical history.Results Among 106 patients,97 patients(91.51%,97/106) had abnormal pap smears of vagina,9 patients (8.49%,9/106) had abnormal pap smears of cervix.Histological analysis revealed that 69 patients were VaIN Ⅰ,24 patients were VaIN Ⅱ,13 patients were VaIN Ⅲ.The high-risk human papilloma virus (HPV) test at diagnosis were positive in 98 patients (92.45%,98/106),negative in 8 patients (7.55%,8/106).Eighty-seven patients VaIN were localized in the upper one third of the vagina,19 patients VaIN were localized in other parts of vaginal wall.Ninety-eight patients VaIN affected to the multifocal vaginal wall,8 patients VaIN affected to the focal vaginal wall.Conclusions It has highly therapeutic value of colposcopy directed biopsy in diagnosis of VaIN.But should closely correlated to past medical history,colposcopy should performed on the whole vagina wall and multiple punch biopsy to elevated positive rate.

Chinese Journal of Postgraduates of Medicine 2010;33(30):8-11
Objective To analyze the clinical characteristics and prognostic factors of endometrial carcinoma in senile women, explore the optimized therapeutic modality. Method The clinic pathological characteristics and survival outcome of 268 patients of endometrial carcinoma in senile women were reviewed retrospectively, and prognostic factors affected the survival of endometrial carcinoma were evaluated. Results According to univariate analysis, therapeutic modality, surgical-pathological classification and pathological grade were closely correlated with prognosis of endometrial carcinoma in senile women(P < 0.01 ). According to COX multivariate analysis,surgical-pathological and pathological grade were independent prognostic associated-factor (P = 0.002,0.000). Conclusions There are closely correlations between prognosis and surgical-pathological classification,therapeutic modality and pathological grade,surgical-pathological classification and pathological grade are independent prognostic associated-factor. The therapy on endometrial carcinoma in senile women should connect with high risk factors and adopt integrating and individual therapeutic modality.
