ABSTRACT
@#Platinum antitumor drugs are widely used for clinical treatment because of their unique antitumor mechanisms, significant antitumor effects, and broad antitumor spectrum. Yet shortcomings such as toxic side effects, drug resistance and cross-resistance of platinum-based drugs have limited their further application. Platinum-intercalator conjugates possess different antitumor mechanisms from those of classic platinum drugs, and have unique advantages in overcoming the disadvantages of classic platinum antitumor drugs. The platinum-intercalator conjugates can be classified into six categories based on the different DNA-intercalator: platinum-acridine, platinum-quinoline, platinum-indole, platinum-naphthalimides, platinum-anthraquinone and platinum-based antitumor agents containing other types of intercalating groups. This article summarizes the research progress of platinum-based antitumor drugs containing DNA insertion groups in recent years.
ABSTRACT
Objective To investigate the application efficacy of oral acetaminophen stapler with compound lidocaine cream combined with lidocaine injection in local anesthesia cystoscopy.Methods From January 2016 to June 2017,180 male patients aged from 60 to 86 years old,whose average age was 71 years old and treated by local anesthesia cystoscopy were collected in this study in the department of Urology of Xuzhou Medical University Affiliated hospital.They were divided into two groups according to the time sequence of visiting doctor.The patients in the research group were treated with oral acetaminophen stapler with compound lidocaine cream and lidocaine injection urethral infusion anesthesia before the examination.The control group was using lidocaine injection urethral infusion anesthesia.To compare the successful rate of operation,operating time and the visual analogue score (VAS) before and after the operation,the patients'limb twist and the tension were observed and recorded.The software of SPSS 16.0 was used for statistical analysis.Results The successful rate of operation in research group and control group was 97.78％ and 91.11％.The VAS score before the operation was (3.2 ± 1.8) and (6.8 ± 2.2).The incidence of complications after treatment was 5.55％ (5/90) and 27.78％ (25/90).The PSS score of 1 h after treatment was (1.1 ± 1.7) and (3.1 ± 1.2).The satisfaction rate was 90.0％ (81/90) and 57.8％(52/90).The differences between the two groups were statistically significant(P ＜ 0.05).However,the opertion time between the two groups was (6.2 ± 1.7) and (6.9 ± 2.1) min.One hour after the opertion,the VAS score was (1.2±0.7) and (1.5±1.1).The score of PSS before the opertionwas (3.4±1.5) and (3.8±1.1).There were no significant differences between the two groups (P ＞ 0.05).Conclusions Taking oral acetaminophen stapler with compound lidocaine cream combined with lidocaine injection in local anesthesia cystoscopy could obviously reduce urethral pain and the anxiety in the opertion of local anesthesia cystoscopy,which obviously superior to use lidocaine injection urethral infusion anesthesia only.The efficacy and safety were definitely and had got better clinical outcomes.

ABSTRACT
Background and purpose:The previous research has found that the prostate stromal cells derived from different prostate zones have distinct effect on prostate epithelial cells. We also revealed that LMO2 protein was highly expressed in PZ stromal cells (PZSCs) and prostate cancer associated fibroblasts (CAFs) compared with TZ stromal cells. This study investigated the effect of LMO2 protein in prostate stromal cells on proliferation and invasion of prostate cancer PC-3 cells and its mechanisms. Methods:Lentivirus overexpression vectors were used to establish LMO2-overexpressed prostate WPMY-1 stromal cell line. shRNA plasmids were used to suppress LMO2 in CAFs. LMO2 mRNA and protein level of both WPMY-1 and CAFs were evaluated by real-time fluorescent quantitative polymerase chain reaction (RTFQ-PCR) and Western blot. Then, PC-3 cells were co-cultured with different prostate stromal cells and the in vitro proliferation and invasion of PC-3 were measured by CCK-8 and matrigel invasion assays respectively. Results:When co-cultured with LMO2-overexpressed prostate stromal cells, both proliferation and in-vasion of PC-3 were improved. However, when co-cultured with CAFs which have inhibited expression of LMO2, the proliferation and invasion of PC-3 were reduced. The protein array proifling found that both interleukin-11 (IL-11) and ifbroblast growth factor-9 (FGF-9) were enhanced extensively in the supernatant collected from LMO2-overexpressed WPMY-1 cells. Conclusion:The expression of LMO2 in prostate stromal cells could be responsible for development of prostate cancer. Paracrine of cytokines, such as IL-11 and FGF-9, from LMO2-overexpressed stromal cells had effects on the proliferation and invasion of prostate cancer cells.
ABSTRACT
Objective To investigate the effect of LMO2 gene,which is overexpressed in prostate peripheral zone than transitional zone,on proliferation and invasion of prostate cancer PC-3 cell line or normal prostate epithelial BPH-1 cell line.Methods Lentivirus overexpression system was used to establish the LMO2 protein overexpressed prostate WPMY-1 stromal cell line.The LMO2 mRNA and protein expression level of those cells was evaluated by qRT-PCR and western blot.The PC-3 or BPH-1 cells was cocultured with prostate stromal cells and the in vitro proliferation and invasion activity were detected by Cell Counting Kit-8 (CCK-8),EdU and Matrigel invasive assays.Results The stable LMO2 overexpressed prostate stromal cells WPMY-1-LMO2 was successfully established.The results of CCK-8,EdU experiments indicated the proliferation and invasion activity of PC-3 or BPH-1 cells were both enhanced through cocultured with WPMY-1-LMO2 cells.The proportion of EdU positive cells of PC-3 cultured in WPMY-1-LMO2 supernatant was (42.67 ± 6.03) ％,and the difference was significant compared with the control group (29.33 ± 3.51) ％ (P ＜ 0.05).The BPH-1 culturcd in the supernatant was (35.00 ± 2.52) ％,aud the difference was significant compared with the control group (23.33 ± 2.52) ％ (P ＜ 0.05).The number of invaded PC-3 or BPH-1 cells after co-cultured with WPMY-1-LMO2 cells was 38 ± 5 and 43 ± 3,respectively,which was significantly different compared with the control group (P ＜ 0.05).Conclusions Tbe LMO2 overexpressed prostate stromal cells could induce proliferation and invasion of PC-3 or BPH-1 cells.The propensity of benign prostatic hyperplasia and prostate cancer at different zones may probably be related to distinctive gene expression between peripheral zone and transitional zone derived stromal cells.
ABSTRACT
Objective To investigate the changes and significances of peripheral blood CD34,KDR/CD34,CD133/CD34,and CD117/CD34 positive cell levels in patients with hemorrhagic stroke at the acute phase. Methods Thirty patients with acute hemorrhagic stroke admitted to the Department of Neurosurgery, Jiangsu Haimen People’s Hospital from September 2013 to April 2014 were enrolled retrospectively. At the same time,20 healthy subjects were selected as a control group. CD34 +,KDR+ /CD34 +,CD133 + /CD34 +, and CD117 + /CD34 +cell levels in peripheral blood were detected in patients with hemorrhagic stroke at day 1 to day 7 after cerebral hemorrhage and the day of physical examination of the control group using FACSCalibur flow cytometry. The data were obtained and analyzed using CELLQuest software. Results Peripheral blood CD34 + cells and KDR+ /CD34 +, CD133 + /CD34 +, CD117 + /CD34 + cells at day 1 to day 7 after ischemic stroke were all lower than control group (all P<0. 05). CD34 + and CD117 + /CD34 + cells decreased firstly at day 1 and 2, then increased gradually;KDR+ /CD34 + and CD133 + /CD34 + cells increased gradually at day 1 to day 5,they were all reached the peak at day 5,which were (14. 8±3. 5) í105 and (16. 7±3. 3) í105 respectively. Compared with that at day 1,CD34 + cells at day 5 and 6 were (27. 4 ±6. 3) í105 and (25. 4 ±5. 7) í105 respectively;KDR+ /CD34 + and CD133 + /CD34 + cells at day 4,5,and 6 were (10. 2±3. 1) í105,(14. 8±3. 5) í105,(12. 1±3. 4) í105 and (14. 3±3. 6) í105,(16. 7±3. 3) í105,and (13. 1±4. 0) í105,respectively;CD117 + /CD34 + cells at day 5 was (21. 3 ±4. 2) í105,which were all higher than the first day after cerebral hemorrhage (P<0.05). In the CD34 + cells,the proportion of KDR+ /CD34 + cells at day 1 to day 7 all decreased compared with the control group (all P<0. 05);the proportion of CD133 + /CD34 + cells at day 4 was (65±4)%,it was higher than the control group (P<0. 05);the proportion of KDR+ /CD34 + cells at day 5 was (55±6)% compared with day 1;the proportion of CD133 + /CD34 + at day 4 was (65 ±4)%;the proportions of CD117 + /CD34 + cells at day 4 and day 5 were (69 ±6)% and (72 ±6)% respectively,and they all increased (all P <0. 05). Conclusion Peripheral blood CD34 + cells and their cell subsets are change in patients with hemorrhagic stroke in acute phase. Speculating the different cell subsets may have different functions and potential. KDR+ /CD34 + and CD133 + /CD34 + may be the early sensitive indicators of acute hemorrhagic stroke,and CD117 + /CD34 + is largely mobilized in early stage.
ABSTRACT
<p><b>OBJECTIVE</b>To assess the effects of warm ischaemia time (WIT) on renalfunction after laparoscopic partial nephrectomy (LPN) for renal masses in patients.</p><p><b>METHODS</b>From January 2010 to December 2012, 39 patients treated with LPN for a single T1 renal tumor were enrolled in this prospective study. There were 24 male and 15 female patients. Their age was (58 ± 10) years old, and their body mass index was (27 ± 3) kg/m(2). The mean operation time was (132 ± 12) minutes, and the mean WIT was (29 ± 8) minutes. Clinical parameters, the single glomerular filtration rates (sGFR) were compared before the operation and after 3 and 12 months in order to observer the effects on renal function and find the factors predicting the renal function impairment.</p><p><b>RESULTS</b>There were significant differences between 3, 12 months after the operation ((26.8 ± 5.6) ml/min and (28.6 ± 5.6) ml/min, respectively) and preoperation ((31.9 ± 6.3) ml/min) in sGFR (F = 4.882 and 5.511, both P < 0.05). And there were significant negative correlations between the sGFR in 3 and 12 months after the operation and WIT (r = -0.569, P = 0.000 and r = -0.448, P = 0.004) . The preoperative sGFR (β = 0.260, 95%CI:0.089-0.431) and WIT (β = 0.369, 95%CI:0.189-0.555) were independent predictors for function decline of the operated kidney (both P < 0.05). The analysis showed that the effects of WIT within 30 minutes on renal function is relatively small. Longer WIT was associated with lower postoperative sGFR values (F = 22.128 and 20.552, both P = 0.000) .</p><p><b>CONCLUSIONS</b>For the LPN operation, the longer of the WIT, the more serious of renal function damage. sGFR is an accurate measurement to assess the renal damage. Every effort should be made to minimise WIT during LPN, and the limit of 30 minutes should be not exceeded.</p>
