Objective To summarize the research progress of gastrointestinal stem cells and its role in gastric neoplasms. Methods The literatures related effect of gastrointestinal stem cells niche， gastrointestinal stem cells markers，and the cancer stem cell theory in the gastric neoplasms were retrieved through PubMed， the research progress of gastrointestinal stem cells and cancer stem cells in the gastric neoplasms was explored. Results The cancer stem cell theory arose a decade ago. Gastrointestinal stem cells played a very important role in the gastric neoplasms， which had specific markers and their niches included many kinds of tissue factors. Inflammation could induce gastrointestinal stem cells dysplasia and become cancer stem cells， which promoted the growth， invasion， and metastasis of the gastric neoplasms. Conclusions Gastric cancer stem cells could be one of an effective target in treatment for gastric neoplasms， and it may be provide a new breakthrough in treatment for gastric neoplasms.
ObjectivesTo systematically review the prophylactic efficacy of lidocaine administrated intravenously in advance on rocuronium associated injection pain/withdrawal movement in patients under general anesthesia.MethodsPubMed, The Cochrane Library, Web of Science, EMbase, CNKI, WanFang Data and VIP databases were electronically searched to collect relevant randomized controlled trials (RCTs) on pretreatment with lidocaine intravenously to prevent injection pain /withdraw movement from rocuronium from inception to September 30th, 2018. Two reviewers independently screened literature, extracted data and assessed risk of bias of included studies; then, meta-analysis was performed by using RevMan 5.3 software.ResultsA total of 30 RCTs involving 2 518 patients were included. The results of meta-analysis showed that, compared to the control group, pretreating with intravenous lidocaine could significantly reduced the occurrence of total pain/withdrawal movement associated with rocuronium injection (RR=0.43, 95%CI 0.36 to 0.51, P<0.000 01), and whether with (RR=0.39, 95%CI 0.29 to 0.52, P<0.000 01) or without (RR=0.45, 95%CI 0.36 to 0.57, P<0.000 01) occluding the vein, intravenous lidocaine could prevent pain/withdrawal movement associated with rocuronium injection. In addition, the incidence of lidocaine group igniting moderate (RR=0.38, 95%CI 0.31 to 0.46, P<0.000 01) or severe (RR=0.23, 95%CI 0.18 to 0.30, P<0.000 01) pain/ withdrawal movement were less likely to occur. However, there was no difference between the lidocaine and control group in the incidence of mild injection pain/withdrawal movement induced by rocuronium (RR=0.89, 95%CI 0.75 to 1.06, P=0.19).ConclusionsCurrent evidence shows that pre-intravenous lidocaine can reduce the occurrence of injection pain/withdrawal movement associated with rocuronium injection patients, especially in the prevention of moderate and severe injection pain/withdrawal movement.
Objective To assess the efficacy and safety of the tubeless approach with a ureteral stent versus nephrostomy tube for postoperative drainage following percutaneous nephrolithotomy, and to provide guidance for clinical practice. Methods Randomized controlled trials (RCTs) were identified from PubMed (1966 to August 2008), Ovid (1966 to August 2008), Embase (1966 to August 2008), The Cochrane Library (Issue 3, 2008) and CBM (1978 to 2008). We also handsearched for relevant published and unpublished reports and check their references. The quality of the included trials was evaluated by two reviewers. We used The Cochrane Collaboration’s RevMan 5.0.16 software for meta-analysis. Results Eight studies involving 507 patients were included. We divided the patients into three groups: small (8~9 Fr), medium (16~18 Fr) and large (20~24 Fr) according to the diameter of nephrostomy tube for the analysis. Our meta-analyses showed: ①Hospital stay (hours): There was no statistically significant difference between tubeless and small bore tubes, but a difference was found in the comparison of tubeless versus medium and large bore tubes [WMD (95%CI) –32.4 (–33.64, –31.16) and –39.07 (–67.75, –10.39), respectively]; ② Puncture site urinary leakage: No statistically significant difference was found between tubeless and small bore tubes, of between tubeless versus medium tubes [RR= 0.07, 95%CI (0.00, 1.15), P=0.06]; ③ Visual analogue scale scores for postoperative pain on Day 1: There was no statistically significant difference between tubeless and small bore tubes, but there was a difference in tubeless versus medium and large bore tubes [MD (95%CI) –2.80 (–2.94, –2.66) and –2.04 (–2.29, –1.79), respectively];④No statistically significant difference was found in transfusion, fever or infection and operating time between tubeless and any size of nephrostomy tube. Conclusion No statistically significant difference between tubeless versus small bore tubes is found for any of the outcome measurements we analysed. Compared with medium and large bore tubes, tubeless PCNL of ureteral stent could reduce hospital stay, urine leakage and postoperative pain without an increase in complications. There is a moderate possibility of selection bias, performance bias and publication bias in this review, because of the small number of the included studies, which weakens the strength of the evidence of our results. Better evidence from more high-quality randomized controlled trials is needed.

ObjectivesThe present network meta-analysis was conducted to evaluate the potential efficacy and safety of various surgical approaches in the treatment of benign prostatic hyperplasia with enlarged prostate.MethodsPubMed, EMbase, The Cochrane Library, Clinicaltrials.gov and CNKI databases were electronically searched to identify eligible studies. Two reviewers independently screened literature, extracted data and evaluated risk of bias and the ADDIS 1.16.8 software was used to conduct meta-analysis.ResultsA total of 23 studies involving 2 849 patients with 5 approaches including open prostatectomy (OP), holmium laser enucleation of the prostate (HoLEP), plasmakinetic/bipolar plasmakinetic enucleation of the prostate (PK/BPEP), transurethral vaporization of the prostate (TUVP), and laparoscopic prostatectomy (LSP) were included. HoLEP, PK/BPEP and OP were superior to the other methods in improving the objective indicators and subjective feelings of patients during both short and medium-term follow-up. However, compared with OP, HoLEP and PK/BPEP were observed to result in a significantly lower hemoglobin level (MD=1.65, 95%CI 0.35 to 4.41; MD=2.62, 95%CI 0.64 to 2.90), longer postoperative irrigation time (MD=4.67, 95%CI 1.29 to 10.66; MD=2.67, 95%CI 1.32 to 6.63), as well as indwelling catheter after operation (MD=1.64, 95%CI 0.48 to 4.15; MD=2.52, 95%CI 0.60 to 3.78). In terms of short-term complications, PK/BPEP (RR=0.45, 95%CI 0.13 to 1.29) was found to be significantly lower than that of OP.ConclusionsHoLEP and PK/BPEP can be probably used as a superior treatment option for large volume benign prostatic hyperplasia because of its better curative effect, higher safety and quick postoperative recovery.
ObjectiveTo explore the impact of different tracts on the effectiveness and safety of percutaneous nephrolithotomy (PCNL) on complete staghorn calculus.MethodsPatients with complete staghorn calculus who underwent single channel PCNL by the same surgeon in West China Hospital of Sichuan University from October 2009 to August 2019 were included. The removing time, the rate of immediate stone removal, the average extubating time, and the incidences of postoperate complications such as fever and bleeding were analyzed statistically.ResultsA total of 379 patients were included. There were 146 cases in the upper tract group, 170 cases in the lower tract group and 63 cases in the middle tract group. Compared with the upper and middle tract groups, the lower tract group had shorter stone removing time [(50.34±18.52) vs. (53.41±22.75) vs. (41.79±17.45) min, P<0.001], shorter average extubating time [(5.53±1.83) vs. (6.17±1.44) vs. (4.96±1.91) d, P=0.007]. The rate of immediate stone removal was higher in the the upper tract group (40.56% vs. 32.79% vs. 34.71% ), but there was no statistical difference among the three groups (P=0.447). There was no significant difference among the three groups in the fever incidence (25.44% vs. 24.24% vs. 26.85%, P=0.938) or bleeding incidence (3.54% vs. 3.03% vs. 4.03%, P=1.000). In addition, there were 8 cases of pleural injury in the upper tract group.ConclusionsCompared with the lower and middle tract, PCNL with upper tract has a higher rate of removing stones for complete staghorn calculus, but there was no significant difference among the three groups. The incidences of bleeding and fever after surgery are similar in the three groups, but the risk of pleural injury may be increased in the upper tract group.
Objective To study the effect of hypoxia on the prol iferation of hBMSCs and human placental decidua basal is-MSCs (hPDB-MSCs), and to provide the theoretical basis for discovering the new seed cells source for tissue engineering. Methods Density gradient centrifugation method was adopted to isolate and culture hBMSCs and hPDB-MSCs,flow cytometry (FCM) was appl ied to detect cell surface marker. After establ ishing the experimental model of CoC12 chemical hypoxia, MTT method was appl ied to evaluate the prol iferation of hBMSCs and hPDB-MSCs at different time points (6, 12, 24, 48, 72, 96 hours) with various CoC12 concentration (0, 50, 75, 100, 125, 150, 175, 200 μmol/L). Results FCM analysis revealed that hPDB-MSCs and hBMSCs expressed CD9, CD29, CD44, CD105, CD106 and human leucocyte antigen ABC (HLA-ABC), but both were absent for CD34, CD40L and HLA-DR. Compared with hBMSCs, hPDB-MSCs expressed stage-specific embryonic antigen 1 (SSEA-1), SSEA-3, SSEA-4, TRA-1-60 and TRA-1-81 better. The prol iferations of hPDB-MSCs and hBMSCs were inhibited within the first 12 hours under hypoxia condition, but promoted after 12 hours of hypoxia. Compared with the control group, the hBMSCs were remarkably prol iferated 24 hours after hypoxia with CoC12 concentration of 150 µmol/L (P lt; 0.05), while hPDB-MSCs were significantly prol iferated 12 hours after hypoxia with CoC12 concentration of 75 µmol/L (P lt; 0.05). Conclusion Compared with hBMSCs, hPDB-MSCs express more specific surface antigens of embryonic stem cells and are more sensitive to the prol iferation effects of chemical hypoxia, indicating it may be a new seed cells source for tissue engineering.
Objective To assess the efficacy of medical expulsive therapy for ureteral calculi with tamsulosin. Methods We searched PubMed, MEDLINE, EMBASE, BIOSIS, International Pharmaceutical Abstracts (IPA) Database, The Cochrane Library and Chinese Journal Full-text Database from 1995 to September 2006, as well as the proceedings of urological scientific conferences from 2000 to 2006. Randomized controlled trials(RCTs) comparing tamsulosin and other therapies for ureteral calculi among adults were included. Data were extracted by two reviewers independently and synthesized by STATA 9.0 software. Results A total of 16 studies involving 1521 patients with distal or juxtavesical ureteral calculi were included. Compared with conservative therapy, tamsulosin showed higher expulsion rate [RR 1.50, 95%CI (1.20 to 1.87), Plt;0.0001], shorter expulsion time [SMD –1.29, 95%CI (–2.27, –0.31)] and fewer patients requiring ESWL or ureteroscopy [RR 0.40, 95%CI (0.27, 0.59), Plt;0.05]. Compared with conservative therapy, the combination of tamsulosin plus deflazacort also showed higher expulsion rate [RR 1.59, 95%CI (1.31, 1.93)], shorter expulsion time [SMD –0.8, 95%CI (–1.18, –0.42)] and fewer patients requiring ESWL or ureteroscopy [RR 0.13, 95%CI (0.06, 0.31), Plt;0.05]. Compared with deflazacort alone, the combination of tamsulosin plus deflazacort demonstrated similar expulsion rate [RR 1.31, 95%CI (0.78, 2.23), P=0.31], but significantly reduced the dosage of analgesics [SMD 15.20, 95%CI (14.98, 15.52)] and decreased the proportion of patients requiring ESWL or ureteroscopy [RR 0.09,, 95%CI (0.02, 0.47), Plt;0.05]. Compared with deflazacort plus nifedipine, the combination of tamsulosin plus deflazacort showed higher expulsion rate [RR 1.20, 95%CI (1.07, 1.35), P=0.002], but similar expulsion time [SMD –1.34, 95%CI (–3.47, 0.79)] and proportion of patients requiring ESWL or ureteroscopy [RR 0.34, 95%CI (0.05, 2.22), Pgt;0.05]. As for side effects, tamsulosin-based treatment and conservative therapy were comparable (Pgt;0.05). Conclusions Tamsulosin has a beneficial effect on the expulsion of ureteral calculi, especially for distal and juxtavesical ureteral calculi. Tamsulosin-based medical expulsive therapy at the dosage of 0.4mg daily is effective and safe for patients with distal ureteral calculi. More large-scale studies are required to define the efficacy of combination therapy of tamsulosin plus deflazacort.
Objective To investigate the feasibil ity of inducing canine BMSCs to differentiate into epithel ial cells in vitro with epithel ial cell conditioned medium (ECCM). Methods Five mL BMSCs were obtained from il iac spine of a healthy adult male canine with weighing 10 kg, and then isolated and cultured. The oral mucosa was harvested and cut into 4 mm × 4 mm after the submucosa tissue was el iminated; ECCM was prepared. BMSCs of the 2nd passage were cultured and divided into two groups, cultured in ECCM as experimental group and in L-DMEM as control group. The cell morphological characteristics were observed and the cell growth curves of two groups were drawn by the continual cell counting. The cells were identified by immunohistochemical staining through detecting cytokeratin 19 (CK-19) and anti-cytokeratin AE1/AE3 on the21st day of induction. The ultra-structure characteristics were observed under transmission electron microscope. Results The cells of two groups showed long-fusiform in shape and distributed uniformly under inverted phase contrast microscope. The cell growth curves of two groups presented S type. The cell growth curve of the experimental group was right shifted, showing cell prol iferation inhibition in ECCM. The result of immunohistochemical staining for CK-19 and anti-cytokeratin AE1/AE3 was positive in the experimental group, confirming the epithel ial phenotype of the cells; while the result was negative in the control group. The cells were characterized by tight junction under transmission electron microscope. Conclusion The canine ECCM can induce allogenic BMSCs to differentiate into epithel ial cells in vitro.
