ABSTRACT
Objective@#To observe the clinical efficacy of Ningmitai capsules, a traditional Chinese medicine using for clearing heat and dampness, in the treatment of residual fragments and postoperative complications following lithotripsy for upper urinary stones.@*Methods@#During October 2016 and March 2018, patients from Wuhan 1st Hospital, Wuhan 2nd Hospital, Wuhan 3rd Hospital, and Wuhan Puai Hospital having upper urinary residual fragments following minimally-invasive stone treatment were randomly assigned to control group and Ningmitai group with a proportion of 1∶3. The patients in control group were treated with antibiotics or sodium diclofenac suppository on demand, while patients in Ningmitai group took additional Ningmitai capsule orally (4 capsules per time, 3 times per day). The observation was started when a patient was enrolled in this study and continued for a maximum of 12 weeks or until stone-free status. During the observation, the stone expulsion time, stone-free time, stone-free rate were observed, and the difference in curative effect between the two groups on postoperative complications such as pain and infection were compared. Statistical analysis was done using t-test or χ2 test by GraphPad Prism 5 software.@*Results@#Totally 269 cases enrolled in this study. Eighty-six patients were from Wuhan 1st Hospital, 69 patients from Wuhan 2nd Hospital, 58 patients from Wuhan 3rd Hospital, 56 patients from Wuhan Puai Hospital, respectively. There were 66 cases in control group and 203 cases in Ningmitai group. The residual fragments expulsion time in Ningmitai group was significantly earlier than that in control group ((4.5±0.4) days vs. (7.5±1.3) days, t=2.877, P=0.004), the residual fragments clearance time in Ningmitai group was significantly shorter than that in control group ((13.6±1.0) days vs.(25.6±3.8) days, t=4.252, P=0.000), and the stone-free rate within 4 weeks post operation in Ningmitai group was significantly higher than control group (91.6% vs. 68.2%, χ2=22.57, P=0.000). After 12 weeks of treatment, the total effective rate of control group was 89.4%, and the total effective rate of Ningmitai group was 99.5%, with statistically significant difference (χ2=17.65, P=0.000). The proportion of caregivers that offered analgesia in Ningmitai group was significantly lower than that in control group (16.3% vs. 30.3%, χ2=6.212, P=0.013), the recovery rate of routine urinalysis following 4 weeks′ treatment was significantly higher in Ningmitai group than that in control group (88.2% vs.71.2%, χ2=10.67, P=0.001). No obvious adverse effects were observed in both groups.@*Conclusions@#Ningmitai capsule can facilitate the stone passage and increase the stone-free rate in the treatment of residual fragments and postoperative complications of upper urinary stones. It is also helpful for the prevention and treatment of postoperative pain, infection and other complications.
ABSTRACT
Objective To investigate the effect of microRNA-1180 transfection on the growth of renal cell carcinoma lines 786-O and ACHN.Methods The renal carcinoma cells were divided into the two groups:control group (transfecting dsControl) and experimental group (transfecting miR-1180).The expression change of p21 mRNA was detected by qRT-PCR.Western blot was conducted to analyze the expression changes of p21,CDK4,CDK6 and CyclinD1 proteins.Flow cytometry (FCM) was used to detect the cell cycle change.The MTS assay was conducted to detect the cell viability and the colony forming assay was performed to examine the cell proliferation ability.Results The qRT-PCR results showed that compared with the negative control dsControl group,after miR-1180 transfection,the expression level of·p21 mRNA in 786-O and ACHN cells was up-regulated to 2.54-fold and 2.49-fold respectively(P＜0.01).The expression trend of p21 protein was consistent with qRT-PCR results.The expression of CDK4,CDK6 and CyclinD1 proteins were significantly down-regulated.The FCM results showed that the proportion of cells in G0/ G1 phase was significantly increased after transfection of miR-1180,but the proportion of cells in S phase and G2/M phase was decreased significantly,indicating that the cell cycle was arrested in G0/G1 phase.The MTS assay results showed that compared with the dsControl group,the viability of the two kinds of renal carcinoma cells was significantly decreased.The colony formation assay showed that the number of colonies formed in the miR-1180 group was smaller,indicating the proliferation ability of miR-1180 transfected cells was decreased.Conclusion miR-1180 can significantly activate the p21 protein expression and inhibit the growth of renal carcinoma cell lines 786-O and ACHN.
ABSTRACT
Objective To investigate the effect of exogenous small RNA (dsP21-397) transfection on growth of human renal clear cell carcinoma cell lines A-498 and Caki-1. Methods The dsControl(control group) and dsP21-397(experimental group)were transfected into A-498 and Caki-1,respectively. The expression of p21 mRNA was analyzed by qRT-PCR. The expression of p21 protein,CDK4 and Cyclin D1 proteins were detected by Western blot. The cell cycle distribution was examined by flow cytometry(FCM). MTS assay and colony formation assay were used to analyze cell viability and proliferation ability. Results Compared with dsControl,p21 mRNA levels in A-498 and Caki-1 cells increased to 2.55-fold(P<0.01)and 2.18-fold(P<0.01),respectively,after transfection with dsP21-397. The expression of p21 protein was up-regulated while the expression of CDK4 and CyclinD1 were down-regulated. The percentage of cells in G0/G1 phase significantly increased after transfection of dsP21-397,and the proportion of cells in S phase and G2/M phase significantly decreased. The activity of A-498 and Caki-1 cells significantly decreased and the number of colonies in the dsP21-397 group was significantly lower. Conclusions dsP21-397 can significantly activate p21 protein expression,down-regulate the cell cycle-associated proteins,and inhibit the growth of renal clear cell carcinoma cells.
