Colonoscopy insertion using water immersion increases the success rate of minimal sedation colonoscopy. Use of the technique leads to a decrease in discomfort, time to reach the cecum, and the amount of sedative and analgesic used, without compromising patient satisfaction.
The sedation outcomes associated with dexmedetomidine compared with those of propofol during drug-induced sleep endoscopy (DISE) remains unclear. Electronic databases (i.e., the Cochrane controlled trials register, Embase, Medline, and Scopus) were searched from inception to 25 December 2020 for randomized controlled trials (RCTs) that evaluated the sedation outcomes with dexmedetomidine or propofol in adult patients diagnosed with obstructive sleep apnea (OSA) receiving DISE. The primary outcome was the difference in minimum oxygen saturation (mSaO2). Five RCTs (270 participants) published between 2015 and 2020 were included for analysis. Compared with dexmedetomidine, propofol was associated with lower levels of mSaO2 (mean difference (MD) = −7.24, 95% confidence interval (CI) −12.04 to −2.44; 230 participants) and satisfaction among endoscopic performers (standardized MD = −2.43, 95% CI −3.61 to −1.26; 128 participants) as well as a higher risk of hypoxemia (relative ratios = 1.82, 95% CI 1.2 to 2.76; 82 participants). However, propofol provided a shorter time to fall asleep and a lower risk of failed sedation compared with dexmedetomidine. No significant difference was found in other outcomes. Compared with propofol, dexmedetomidine exhibited fewer adverse effects on respiratory function and provided a higher level of satisfaction among endoscopic performers but was associated with an elevated risk of failed sedation.
Background:
Systemic Lupus Erythematosus (SLE) is a diffuse connetive tissue disease, which is difficult to be conquered. However, the traditional Chinese medicine is significant in the treatment. And the Chinese medicine tripterygium and its plant extraction can help us to overcome this disease, to some extent.
Methods:
The deadline should be from inception to February 2020 by computer from the databases: the Cochrane Library, Pubmed, Embase, Web of Science in English and the Chinese National Knowledge Infrastructure, Wanfang Database, Chinese Biomedical Literature Database and Chinese Science, Chinese Traditional Medicine Database, Chinese Science and Technology Periodical Database in Chinese. Included criteria are randomized controlled trials. The primary outcomes are the clinical symptoms, systemic lupus erythematosus disease activity index and quality of life questionnaire (the top 10 frequency). We will use RevMan 5.0 statistical software for data synthesis, sensitivity analysis, meta regression, subgroup analysis, and risk of bias assessment. The publish bias will be assessed by a funnel plot and the funnel plot symmetries will be evaluated by Begg and Egger tests. We will use the Grading of Recommendations Assessment, Development and Evaluation system to assess the quality of evidence.
Results:
This article will give a protocol for meta analysis which can make sure the efficacy and side effect of the tripterygium and its plant extraction for SLE.
Conclusion:
The efficacy and side effect of the tripterygium and its plant extraction for SLE will be evaluated.
Ethics and dissemination:
Without personal information involved, ethical approval and informed consent form is no need. The review will be submitted to a peer-reviewed journal prospectively to spread our findings.

Prostate cancer is featured by its heterogeneous nature, which indicates a different prognosis. Castration-resistant prostate cancer (CRPC) is a hallmark of the treatment-refractory stage, and the median survival of patients is only within two years. Neuroendocrine prostate cancer (NEPC) is an aggressive variant that arises from de novo presentation of small cell carcinoma or treatment-related transformation with a median survival of 1–2 years from the time of diagnosis. The epigenetic regulators, such as long non-coding RNAs (lncRNAs) and microRNAs (miRNAs), have been proven involved in multiple pathologic mechanisms of CRPC and NEPC. LncRNAs can act as competing endogenous RNAs to sponge miRNAs that would inhibit the expression of their targets. After that, miRNAs interact with the 3’ untranslated region (UTR) of target mRNAs to repress the step of translation. These interactions may modulate gene expression and influence cancer development and progression. Otherwise, epigenetic regulators and genetic mutation also promote neuroendocrine differentiation and cancer stem-like cell formation. This step may induce neuroendocrine prostate cancer development. This review aims to provide an integrated, synthesized overview under current evidence to elucidate the crosstalk of lncRNAs with miRNAs and their influence on castration resistance or neuroendocrine differentiation of prostate cancer. Notably, we also discuss the mechanisms of lncRNA–miRNA interaction in androgen receptor-independent prostate cancer, such as growth factors, oncogenic signaling pathways, cell cycle dysregulation, and cytokines or other transmembrane proteins. Conclusively, we underscore the potential of these communications as potential therapeutic targets in the future.
Purpose: To investigate the association of prostate blood flow (PBF) with lower urinary tract symptoms (LUTS) in aged males using Doppler spectral waveform (DSW) analysis. Patients and Methods: We performed a prospective analysis involving 133 aged males with clinical diagnosis of LUTS. DSW parameters (peak-systolic velocity (PSV), end-diastolic velocity (EDV), and resistive index (RI)) were measured at bilateral neurovascular bundles (NVB), periurethral, and capsular branches by Doppler transrectal ultrasound with the patient in the right lateral decubitus position. The associations of PBF parameters and the International Prostate Symptom Score (IPSS) were analyzed. Results: Overall, total IPSS scores were significantly correlated with the RI of bilateral NVB vessels (r2 = 0.03, 0.04; p = 0.04, 0.02, respectively), and PSV of left NVB vessels. PSV of bilateral NVB vessels were associated with the storage score (p = 0.022 and p = 0.016), but not with the voiding score. The sum of the frequency and urgency score was also associated with EDV of both capsular and urethral branches (p = 0.043 and p = 0.009, respectively), and PSV of NVB vessels on both sides (p = 0.045 and p = 0.019, respectively). Conclusions: There is an association between PBF and LUTS, especially with storage symptoms. The findings may provide some insights in understanding the underlying pathophysiology of lower urinary tract dysfunction.
Purpose: Lymphovascular invasion (LVI) and systemic immune-inflammation index (SII) both have been proved to correlate with oncologic outcomes in upper tract urothelial carcinoma (UTUC). We hypothesize that integrating SII with LVI may be an aid for risk-stratification of prognosis. This study aimed to evaluate the prognostic significance of combined SII and LVI in patients with localized UTUC. Patients and Methods: A retrospective analysis of clinicopathological data of 554 UTUC patients who underwent radical nephroureterectomy (RNU) was conducted. The SII was calculated using the equation (preoperative serum neutrophil*platelet/ lymphocyte). Use of Kaplan-Meier analyses and Cox proportional hazards models were to evaluate associations of combining SII and LVI with overall survival (OS), cancer-specific survival (CSS), and progression-free survival (PFS). Furthermore, receiver operating characteristic (ROC) analysis was applied to estimate predictive ability of combining SII and LVI for oncological outcomes. Results: Positive LVI was significantly associated with advanced stage, high grade, necrosis, lymph node metastasis, and high-level SII. Positive LVI and high-level SII co-existence was significantly associated with unfavorable OS, CSS, and PFS in Kaplan-Meier analyses (all p < 0.001) and was an independent indicator of OS, CSS, and PFS (HR [95%
