Objective. To evaluate the beneficial and adverse effects of breviscapine injection in combination with antihypertensive drugs for treating hypertensive nephropathy in clinical practice. Methods. We searched PubMed, the Cochrane Library, Embase, CNKI, Sino Med, VIP, and Wanfang Data for relevant literature. The timeframe of retrieval was set from the founding date of each database to September 28, 2018. Results. Fourteen papers were included in this study. The quality of all the studies included was determined to be low. All studies were conducted with Chinese populations. Meta-analysis showed that, compared with single-use antihypertensive drugs, using breviscapine injection in combination with antihypertensive drugs to treat hypertensive nephropathy can reduce serum creatinine (Scr) [WMD = –35.16, 95% CI(–50.01, –20.31), P ≤ 0.001], blood urea nitrogen (BUN) [WMD = –2.00, 95% CI(–3.07, –0.94), P ≤ 0.001], 24-hour urinary total protein (24 h UTP) [WMD = –0.04, 95% CI(–0.05, –0.02), P ≤ 0.001], and the beta-2-microglobulin (B2M) [WMD = –0.09, 95% CI(–0.11, –0.07), P ≤ 0.001], improve creatinine clearance rate (Ccr) [WMD = 7.84, 95% CI(5.20, 10.49), P ≤ 0.001], and increase the clinical efficacy [RR = 1.27, 95% CI(1.05, 1.53), P = 0.014], but does not lower systolic blood pressure (SBP) [WMD = –1.02, 95% CI(–2.88, 0.84), P = 0.281]. There was no significant difference in adverse events between experimental groups and control groups. Conclusion. Breviscapine injection in combination with antihypertensive drugs can improve clinical efficacy and Ccr and reduce Scr, BUN, 24 h UTP, and B2M in patients with hypertensive nephropathy. The present meta-analysis indicated that breviscapine injection can serve as a renal protective effect to patients with hypertensive nephropathy. However, the evidence of methodological quality and sample sizes is weak, and thus, further standardized research is required.

Background. Changes in thyroid function in diabetes patients who developed diabetic ketoacidosis (DKA) still need to be fully elucidated. The aim of this study was to systematically review available data on the relationship between thyroid function and DKA in diabetes patients who developed DKA. Methods. Electronic databases (PubMed, EMBASE, Cochrane Library, and China Academic Journal Full-text Database (CNKI)) were searched systematically to search relevant literature before December 2020. The mean ± standard deviation and 95% confidence interval (95% CI) were used for evaluation, and sensitivity analysis was performed. Publication bias was estimated by funnel plot, Egger’s test, and Begger’s test. Results. 29 studies were included in the meta-analysis, and the indicators (T4, T3, FT3, FT4, TSH, T3RU, and rT3) of patients with DKA were compared and analyzed. The results of this study showed that the levels of T4, T3, FT3, FT4, and TSH were decreased and the level of rT3 was increased in patients with DKA. Compared with after treatment, the levels of T4, T3, FT3, and FT4 in patients with DKA were decreased before treatment, while the levels of rT3 were increased, and there was no significant difference in changes of TSH. With the aggravation of DKA, the levels of T4, T3, FT3, and FT4 will further decrease, while the changes of TSH have no statistical difference. Conclusion. Thyroid function changed in diabetic patients with DKA. It changed with the severity of DKA. This condition may be transient, preceding further recovery of DKA.

<b><i>Introduction:</i></b> This meta-analysis aimed to explore the preventive effects of combined statin and antihypertensive therapy on major cardiovascular outcomes in patients with hypertension. <b><i>Methods:</i></b> PubMed, Embase, and the Cochrane Library databases and reference lists of published studies were systematically searched throughout October 9, 2019. Studies designed as randomized controlled trials and investigating the effects of combined statin and antihypertensive therapy versus antihypertensive therapy alone were included. Data abstraction and quality of included studies were assessed by 2 independent authors. The summary results were calculated using relative risks (RRs) with 95% CIs employing a random-effects model. <b><i>Results:</i></b> A total of 8 randomized controlled trials including 38,618 patients were finally enrolled. The summary RRs indicated that the combined therapy significantly reduced the risk of major adverse cardiovascular events compared with antihypertensive therapy alone (RR 0.79; 95% CI 0.71–0.88; <i>p</i> &#x3c; 0.001). Furthermore, the patients in the combined therapy group also experienced less myocardial infarction (RR 0.67; 95% CI 0.53–0.84; <i>p</i> = 0.001) and stroke risks (RR 0.82; 95% CI 0.72–0.94; <i>p</i> = 0.005), while no significant difference was observed between combined therapy and antihypertensive therapy alone regarding cardiac death (RR 0.96; 95% CI 0.84–1.08; <i>p</i> = 0.465) and all-cause mortality (RR 0.95; 95% CI 0.86–1.04; <i>p</i> = 0.277). <b><i>Conclusion:</i></b> These findings suggested that combined statin and antihypertensive therapy was associated with more cardiovascular benefits compared with antihypertensive therapy alone.

Abstract Background: Acromegaly is a rare, chronic and severe disease. Drug therapy including somatostatin analogues, dopamine receptor agonists and growth hormone receptor antagonists are commonly used to treat patients who do not respond to surgery. The use of combination therapy with PEG and SAs has become more common over the last decade. We performed this study to accurately evaluate the effect of combination therapy of somatostatin analogues (SAs) with pegvisomant (PEG) on acromegalic patients. Methods: PubMed, EMBASE, The Cochrane Library, ClinicalTrials.gov, Scopus, Web of Science, Chinese Biomedical Literature Database and Trip database were searched for relevant studies. Prospective clinical trials treating acromegaly with the co-administration of SAs and PEG were included. We performed a meta-analysis by using Stata 12.1 . Sensitivity analysis was conducted to explore heterogeneity. Results : Eight studies were included in this meta-analysis. The overall rate of serum insulin-like growth factor 1 (IGF-1) normalization was 66% (95% CI: 52%–78%; I 2 =62.59%). The combination therapy did not significantly change patients’ fasting plasma glucose (ES: 0.011 mmol*L -1 ; 95% CI: −0.374 to 0.397 mmol*L -1 ; P=0.954) or glycosylated haemoglobin (ES: -0.074%; 95% CI: −0.166% to 0.315%; P=0.544) while decreasing the fasting plasma insulin (ES: −21.487 pmol*L-1; 95% CI: −35.713 to -7.260 pmol*L-1; P=0.003). Elevation of liver enzyme levels was found in 14% (95% CI: 8% to 21%) of the patients. There was no significant difference for serious adverse events and treatment discontinuation due to adverse event between SAs monotherapy group and combination therapy group. Conclusions: Combined therapy of SAs and PEG effectively normalized IGF-1 levels in most of the patients whose IGF-1 level was greater than the upper limit of normal after high dose SAs monotherapy. The therapy also decreased significantly FPI levels with a neutral effect on glucose parameters in acromegaly patients. Moreover, elevated liver enzyme levels were observed in a small number of patients, which suggests a need for liver function monitoring. Trial registration We have our protocol registered in PROSPERO. (Registration number: CRD42019115549)

Study Design: Systematic review and meta-analysis. Objective: To systematically review the available articles on topical vancomycin powder (TVP) use in pediatric spine surgeries exploring the usefulness and safety of such practice. Methods: We conducted an independent and duplicate electronic database search in PubMed, EMBASE, and Cochrane Library till March 2020 to identify all relevant literature on the use of TVP for pediatric spine surgeries. Surgical site infection (SSI) rate, specific reported complications, reoperation rate, microbial flora pattern in reported SSIs, and safety profile were the outcomes analyzed. Analysis was performed with the R platform using OpenMeta[Analyst] software. Results: No prospective studies were available to evaluate the use of TVP in pediatric spine surgeries for the prevention of SSIs. Neither standardized protocol, nor drug dosage, nor safety profile was established for pediatric use. Three retrospective cohort studies including 824 patients (TVP/control: 400/424) were included in the meta-analysis. There was low-quality evidence suggesting no significant difference between the 2 groups in SSI rate (RR = 0.474; 95% CI = [0.106,2.112]; P = .327) with significant heterogeneity ( I 2 = 70.14; P = .035). The TVP group showed a significant benefit on cost analysis in one of the included studies. However, TVP did not prevent gram-negative coinfection on SSI in the TVP group. Conclusion: From the literature available at present, TVP does not qualify to be recommended as a safe and useful option to prevent SSI following pediatric spine surgeries. High-quality prospective interventional studies are needed to arrive at a consensus on its use along with appropriate dosage and method of application.

Clinical Relevance The use of laser light during bleaching will not reduce the incidence or severity of sensitivity and will not increase the degree of color change compared with nonlaser light sources. SUMMARY Objective: To evaluate whether the use of laser during in-office bleaching promotes a reduction in dental sensitivity after bleaching compared with other light sources. Methods: The present review was conducted following the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) and is registered with PROSPERO (CDR42018096591). Searches were conducted in the PubMed/Medline, Web of Science, and Cochrane Library databases for relevant articles published up to August 2018. Only randomized clinical trials among adults that compared the use of laser during in-office whitening and other light sources were considered eligible. Results: After analysis of the texts retrieved during the database search, six articles met the eligibility criteria and were selected for the present review. For the outcome dental sensitivity, no significant difference was found favoring any type of light either for intensity (mean difference [MD]: −1.60; confidence interval [CI]: −3.42 to 0.22; p=0.09) or incidence (MD: 1.00; CI: 0.755 to 1.33; p=1.00). Regarding change in tooth color, no significant differences were found between the use of the laser and other light sources (MD: −2.22; CI: −6.36 to 1.93; p=0.29). Conclusions: Within the limitations of the present study, laser exerts no influence on tooth sensitivity compared with other light sources when used during in-office bleaching. The included studies demonstrated that laser use during in-office bleaching may have no influence on tooth color change.

Background: It has been found that there is a link between hypertension and elevated risk of Alzheimer’s disease (AD). Herein, a meta-analysis based on randomized clinical trials (RCTs) was used to assess the effect of antihypertensive drugs on cognition and behavioral symptoms of AD patients. Method: The three databases – PubMed/Medline, Scopus, and Cochrane Library- were searched up to March 2020. The quality of the studies included in the meta-analysis was evaluated by the Jadad score. Clinical Global Impression of Change (CGIC) included in two studies, Mini-Mental State Examination (MMSE) included in three studies, and Neuropsychiatric Inventory (NPI) in three studies were the main outcomes in this systematic review. Results: Out of 1506 studies retrieved in the databases, 5 RCTs included and analyzed in the meta-analysis. The pooled mean differences of CGIC, MMSE, and NPI in patients with AD receiving antihypertensive drugs compared to placebo was -1.76 with (95% CI = -2.66 to -0.86; P=0.0001), 0.74 (95% CI = 0.20 to 1.28; P= 0.007), and -9.49 (95% CI = -19.76 to 0.79; P = 0.07), respectively. Conclusion: The findings of the present meta-analysis show that antihypertensive drugs may improve cognition and behavioral symptoms of patients with AD. However, more well-designed RCTs with similar drugs are needed to achieve more conclusive results.

Background: β-amyloid (Aβ) accumulates abnormally to senile plaque which is the initiator of Alzheimer's disease (AD). As one of the Aβ-degrading enzymes, Insulin-degrading enzyme (IDE) remains controversial for its protein level and activity in Alzheimer's brain. Methods: The electronic databases PubMed, EMBASE, The Cochrane Library, OVID and Sinomed were systemically searched up to Sep. 20th, 2017. And the published case-control or cohort studies were retrieved to perform the meta-analysis. Results: Seven studies for IDE protein level (AD cases = 293; controls = 126), three for mRNA level (AD cases = 138; controls = 81), and three for enzyme activity (AD cases = 123; controls = 75) were pooling together. The IDE protein level was significantly lower in AD cases than in controls (SMD = - 0.47, 95% CI [-0.69, -0.24], p < 0.001), but IDE mRNA and enzyme activity had no significant difference (SMD = 0.02, 95% CI [-0.40, 0.43] and SMD = 0.06, 95% CI [-0.41, 0.53] respectively). Subgroup analyses found that IDE protein level was decreased in both cortex and hippocampus of AD cases (SMD = -0.43, 95% CI [-0.71, -0.16], p = 0.002 and SMD = -0.53, 95% CI [-0.91, -0.15], p = 0.006 respectively). However, IDE mRNA was higher in cortex of AD cases (SMD = 0.71, 95% CI [0.14, 1.29], p = 0.01), not in hippocampus (SMD = -0.26, 95% CI [-0.58, 0.06]). Conclusions: Our results indicate that AD patients may have lower IDE protease level. Further relevant studies are still needed to verify whether IDE is one of the factors affecting Aβ abnormal accumulation and throw new insights for AD detection or therapy.

Abstract Background Mitochondria are essential organelles that provide energy for cellular functions, participate in cellular signaling and growth, and facilitate cell death. Based on their multifactorial roles, mitochondria are also critical in the progression of critical illnesses. Transplantation of mitochondria has been reported as a potential promising approach to treat critical illnesses, particularly ischemia reperfusion injury (IRI). However, a systematic review of the relevant literature has not been conducted to date. Here, we systematically reviewed the animal and human studies relevant to IRI to summarize the evidence for mitochondrial transplantation. Methods We searched MEDLINE, the Cochrane library, and Embase and performed a systematic review of mitochondrial transplantation for IRI in both preclinical and clinical studies. We developed a search strategy using a combination of keywords and Medical Subject Heading/Emtree terms. Studies including cell-mediated transfer of mitochondria as a transfer method were excluded. Data were extracted to a tailored template, and data synthesis was descriptive because the data were not suitable for meta-analysis. Results Overall, we identified 20 animal studies and two human studies. Among animal studies, 14 (70%) studies focused on either brain or heart IRI. Both autograft and allograft mitochondrial transplantation were used in 17 (85%) animal studies. The designs of the animal studies were heterogeneous in terms of the route of administration, timing of transplantation, and dosage used. Twelve (60%) studies were performed in a blinded manner. All animal studies reported that mitochondrial transplantation markedly mitigated IRI in the target tissues, but there was variation in biological biomarkers and pathological changes. The human studies were conducted with a single-arm, unblinded design, in which autologous mitochondrial transplantation was applied to pediatric patients who required extracorporeal membrane oxygenation (ECMO) for IRI–associated myocardial dysfunction after cardiac surgery. Conclusion The evidence gathered from our systematic review supports the potential beneficial effects of mitochondrial transplantation after IRI, but its clinical translation remains limited. Further investigations are thus required to explore the mechanisms of action and patient outcomes in critical settings after mitochondrial transplantation. Systematic review registration The study was registered at UMIN under the registration number UMIN000043347.

Objective To compare the clinical efficacy and safety of dexmedetomidine and propofol in patients who underwent gastrointestinal endoscopy. Methods Relevant studies comparing dexmedetomidine and propofol among patients who underwent gastrointestinal endoscopy were retrieved from databases such as PubMed, Embase, and Cochrane Library. Results Seven relevant studies (dexmedetomidine group, n = 238; propofol group, n = 239) met the inclusion criteria. There were no significant differences in the induction time (weighted mean difference [WMD] = 3.46, 95% confidence interval [CI] = −0.95–7.88, I2 = 99%) and recovery time (WMD = 2.74, 95% CI = −2.72–8.19, I2 = 98%). Subgroup analysis revealed no significant differences in the risks of hypotension (risk ratio [RR] = 0.56, 95% CI = 0.25–1.22) and nausea and vomiting (RR = 1.00, 95% CI = 0.46–2.22) between the drugs, whereas dexmedetomidine carried a lower risk of hypoxia (RR = 0.26, 95% CI = 0.11–0.63) and higher risk of bradycardia (RR = 3.01, 95% CI = 1.38–6.54). Conclusions Dexmedetomidine had similar efficacy and safety profiles as propofol in patients undergoing gastrointestinal endoscopy.
