等離子雙極電切技術(shù)在前列腺增生患者中的應(yīng)用研究
[Abstract]:Part 1 a comparative study of the effects of domestic and imported plasma bipolar electrotangent rings on the histopathology of prostatic prostate in dogs. Objective: To compare the histopathological effects of domestic and imported plasma bipolar rings on the histopathology of the prostate in dogs. Methods: 18 adult male hybrid dogs were randomly divided into 2 groups: the imported electric cutting ring group (9), and the domestic electric cut ring group (9 0 after the operation (immediately after the operation), the animals were sacrificed at 1,6 weeks and the prostate specimens were obtained. The pathological changes of the prostate tissue were observed under the light microscope and the thickness of the solidified layer of the wound was measured. Results: the thickness of the coagulation layer of the prostate tissue in the imported electric cutting ring group and the domestic electric cutting ring group was (235.45 + 25.37) mu m respectively, (110.87 +). 20.23) mu m and (238.12 + 32.47) mu m, (112.64 + 18.76) mu m, there was no significant difference in the two groups after the operation (P0.05). 6 weeks after the operation, the coagulation layer of the wound surface of the prostate tissue in the imported electric cutting ring group and the domestic electrocut ring group was completely off, and the wound was covered with the regenerated urinary tract epithelium. After 0,1,6 weeks after the operation, the imported electric cutting ring group and the domestic electric cutting ring group were in the forefront. The adenoid tissues have different degrees of inflammation, the dilatation of the lumen and the destruction of the epithelium under the solidified layer. Conclusion: the pathological effects of the imported electrotangent ring and the domestic electrotangent ring on the wound of the prostate tissue are basically similar. The application of second parts of the prostatic plasma bipolar electrocutting technique in the treatment of large volume prostatic hyperplasia (80g) Objective: To study the application and clinical effect of transurethral prostatic plasma bipolar electrosurgical resection (PKRP) in patients with prostatic hyperplasia (prostate volume greater than 80g) and to compare the therapeutic effect of PKRP on patients with different prostate volumes. Methods: a retrospective analysis of the prostatic hyperplasia in the Department of Urology of our hospital in December January 2011 after the treatment of PRKP in the Department of urology. The basic information of the patients (prostate volume greater than 80g) was collected, including preoperative parameters (age, size of the prostate, Qmax, residual urine, IPSS, fPSA, fPSA blood Hb, blood Na+) and postoperative index (hospitalization days (H), operation time (min), catheterization time, reoperation, or blood transfusion) at the same time according to the volume of the prostate. Two groups: 80-100g and 100g. Through the above two groups of age, the size of the prostate, Qmax, residual urine, IPSS, fPSA, fPSA, blood Hb, blood Na+, the days of hospitalization (H), operation time (min), tube time and other results were carried out t test and statistical analysis, the difference between the two groups of the two groups was statistically significant. 40 patients were treated with PKRP, and the pathological report of.40 PKRP after operation was benign prostatic hyperplasia. The age of the patients treated with PKRP was (72.3 + 6.65) years old. The size of the prostate was (101.05 + 18.78) g, Qmax (7.25 + 2.62) ml/s, residual urine volume (131.09 + 139.63) ml, IPSS (19.97 + 7.12), Total PSA (13.11 + 12.31) ng/. L, f/t PSA (0.226 + 0.082), preoperative Hb (129.65 + 11.58) g/L, preoperative blood Na+ (141.34 + 2.62) mmol/L, total operation time (112 + 40.62) min, resection weight (60 + 17.02) g, hospitalization time (25.475 + 8.464) days, and catheterization time (166.05 + 91.09) H. after surgery for bleeding and reoperation. After transurethral resection of the prostate, the patients with adenosine hyperplasia showed that the 80-100g prostatic group (n=23) and the prostate group above 100g (n=1 7) were excised (51.52 + 11.02g vs.71.47 + 17.21g) after PKRP, and the number of hospitalized days (23.17 + 7.50d vs.28.59 +. 8.91d), and the number of reoperations (0 vs.1) and the number of blood transfusion (0) had significant statistical differences. P0.05).35 patients were followed up by telephone. The follow-up time was 5-17 months after the operation, and the IPSS score was 2.51 + 1.15. Only one case had a slightly worse erectile function than before the operation. No patients needed reoperation after discharge. No patients had urinary incontinence, 7 patients had retrograde ejaculation and 20 cases of urinary tract infection. Conclusion: PKRP was used to treat the large volume of prostate. The prostatic hyperplasia at 80g is safe and effective. By using saline as an intraoperative irrigation fluid, it clearly eliminates the risk of TUR syndrome and has no obvious effect on sexual function..PKRP is a promising form for the treatment of the large prostate. It should be more popularized and applied in the Department of urology. The third part of the Bcl-2 protein expression should be expressed. Meta analysis of the risk of prostate cancer risk in Chinese people: use the NETA analysis method to systematically evaluate the correlation between Bcl-2 protein expression and the different clinicopathological features of prostate cancer in Chinese population. Methods: PubMed, Embase, CBM, CNKI, VIP and WanFang Data databases were retrieved by computer to search for the expression of Bcl-2 protein. A case-control study on the correlation between prostate cancer and its different clinicopathological features in Chinese people, the retrieval time was from the establishment of the library to March 2016. 2 evaluators were selected independently, the data extraction and the methodological quality evaluation, and then the RevMan 5.3 software for Meta analysis. Results: the final inclusion of 24 case control studies, Among the 1081 cases of prostate cancer and 178 cases of normal prostate control, the results of.Meta analysis showed that the expression of Bcl-2 protein in prostate cancer patients was higher than that of [OR=3.27,95%CI (1.68,6.38), P=0.0005], and [OR=3.77,95%CI (1.81,7.88) and P=0.0004], and the difference was statistically significant higher than that of normal prostate control; in prostate cancer, the prostate cancer was statistically significant. The expression of Bcl-2 protein in low differentiation group was higher than that of high group [OR=3.60,95%CI (2.51,5.16), P0.00001]. The expression of Bcl-2 protein in J-W-P stage group C+D group was higher than that of A+B stage group [OR=2.17,95%CI (1.23,3.84), P=0.008], and the expression of Bcl-2 protein in prostate cancer group was higher than that of non metastasis group. Conclusion: there is a significant correlation between the expression of Bcl-2 protein and the prostatic cancer and its clinicopathological features in Chinese population. The above conclusions need to be further developed and verified by high quality research. The fourth part of E-cadherin expression is related to the risk of prostate cancer in Chinese population. Meta analysis objective: to systematically evaluate the correlation between E-cadherin expression and the different clinicopathological features of prostate cancer in Chinese population by NETA analysis. Methods: the database of PubMed, Embase, CBM, CNKI, VIP and WanFang Data was retrieved by computer to collect the expression of prostate cancer and its different clinical diseases in Chinese population. The clinical study of the correlation of physical characteristics was from the establishment of the library to December 2015. The 2 evaluators were selected and extracted independently according to the exclusion criteria. Then the Meta analysis was carried out by RevMan5.3 software. Results: the results were included in 21 studies, including 920 cases of prostate cancer, 415 cases of prostatic hyperplasia and normal prostate. The results of.Meta analysis in 48 cases of tissue group showed that the expression of E-cadherin in prostate cancer group was significantly lower than that of [OR=0.07,95%CI (0.05,0.11), P0.01] and normal prostate tissue [OR=0.04, 95%CI (0.01,0.18), P0.01], and the expression of E-cadherin in prostate cancer tissue was increased with the pathological grading and clinical stage of prostate cancer. Conclusion: there is a significant correlation between the low expression of E-cadherin and the clinicopathological characteristics of prostate cancer in Chinese population and its clinicopathological features. The conclusion needs further high quality research to be verified. The fifth part of the expression of Survivin protein and the expression of Survivin protein in the Chinese population Meta analysis of the risk related prostate cancer risk in Chinese people: Meta analysis was used to evaluate the correlation between the expression of Survivin protein and the different clinicopathological features of prostate cancer in Chinese population. Methods: the database of PubMed, Embase, CBM, CNKI, VIP and WanFang Data was retrieved by computer to search for the expression of Survivin protein and China A case control study of the correlation between prostate cancer and its different clinicopathological features was studied. The retrieval time was from the establishment of the library to November 2015. 2 authors were screened independently by the inclusion criteria, the data extraction and the quality evaluation were evaluated, and the RevMan 5.3 software was used for the Meta analysis. The results were included in the final 32 cases. In the control study, 1613 cases of prostate cancer, 708 cases of prostatic hyperplasia and 93 cases of normal prostate tissue group.Meta analysis showed that the expression of Survivin protein in prostate cancer group and prostatic hyperplasia group [OR=32.95,95%CI (19.88,54.63), P0.01], prostate cancer group and normal prostatic gland group [OR=75.78,95%CI (26.97212.98), P0.01] expression. The differences were statistically significant, Survivin protein in the low differentiation group and the high group [OR=4.45,95%CI (3.13,6.32), P0.01], J-W-P stage C+D group and A+B stage [OR=5.42,95%CI (2.91,10.10), P0.01], lymph node metastasis group and no lymph node metastasis group [OR=4.07,95%CI (2.91,10.10), differences in expression. Conclusion: there is a significant correlation between the expression of Survivin protein and the prostatic cancer and its clinicopathological features in Chinese population.
