Chinese herbal compounds containing scorpion in the treatment of epilepsy: A protocol for systematic review and meta-analysis

Background:Epilepsy is 1 of the common neurodevelopmental diseases. It can affect about 0.5% to 1.0% of the population regardless of their race and social class. Despite the development of a wide range of treatments, there remaining about one-third of patients still experience seizures. Chinese herbal compounds containing scorpion (CHCCS) have shown an outstanding curative effect on nerve protection and epilepsy. But there''s no study to assess its clinical efficacy and safety.Methods:Each data of CHCCS in treating epilepsy from related English and Chinese databases will be searched. The primary outcome is the efficacy of the CHCCS on epilepsy. And the secondary outcomes include recurrence rate and side effects. The risk of bias will be assessed, and RevMan5.3 and Stata14.0 will be performed for meta-analysis. Finally, we will assess the level of the resulting evidence.Results:The results of the study will be combined with current evidence and published in a peer-reviewed journal.Conclusions:This study will specifically investigate the effectiveness and safety of CHCCS in treating epilepsy.INPLASY registration number:INPLASY202120056.     

The meta-analysis of the effect of 68Ga-PSMA-PET/CT diagnosis of prostatic cancer compared with bone scan

Background:⁶⁸Ga-PSMA-PET/CT (positron emission tomography/computed tomography) is a promising method for prostate cancer (PC) detection. However, the ability of ⁶⁸Ga-PSMA-PET/CT to detect malignant bone lesions, and whether this method is superior to the existing bone imaging methods are still lack of systematic analysis.Purpose:To evaluate the value of ⁶⁸Ga-PSMA-PET/CT and bone scan in clinical diagnosis of prostatic cancer from the perspective of evidence-based medicine.Methods:PubMed, The Cochrane Library, EMBASE, Springer Link, Sinomed, CNKI, Wanfang database, and CQVIP database were searched to find the satisfactory studies that needed systematic review of trials and compared the value of 68Ga-PSMA-PET/CT and bone scan. All studies published from inception to March 31, 2020. According to the inclusion and exclusion criteria, 2 reviewers independently evaluated and extracted the literature. Review Manager 5.3 was applied to evaluate the included literature quality. The heterogeneity of the included literature was tested by Meta Disc 1.4, and the effect model was selected according to the heterogeneity test results, and the sensitivity (SEN), specificity (SPE), PLR, NLR and diagnostic odds ratio (DOR) were analyzed. After testing the heterogeneity results of literature by using the 95% confidence interval and the forest map.Results:A total of 4 studies were eligible for inclusion in the meta-analysis, which included 318 patients, 120 cases with bone metastasis and 198 cases without bone metastasis. The results of summary evaluation for ⁶⁸Ga-PSMA-PET/CT and bone scan in diagnosis of prostatic cancer as follow respectively: The SEN were 0.97 and 0.86; the SPE were 1.00 and 0.87; the DOR were 1468.33 and 36.23; PLR were 88.45 and 6.67; NLR were 0.05 and 0.19; and the area under curve (AUC) and 95% CI were 0.9973 (1.0000–0.9927) and 0.8838 (0.9584–0.8092).Conclusion:By comparing the diagnostic results of ⁶⁸Ga-PSMA-PET/CT and bone scan imaging diagnosis methods, the ⁶⁸Ga-PSMA-PET/CT has a higher SEN and SPE than bone scan, and it has a higher diagnostic efficiency for prostate cancer bone metastasis, which is worthy of clinical application.     

CHA2DS2-VASc score predicts the slow flow/no-reflow phenomenon in ST-segment elevation myocardial infarction patients with multivessel disease undergoing primary percutaneous coronary intervention

ST-segment elevation myocardial infarction (STEMI) patients with multivessel disease (MVD) have a higher incidence of slow-flow/no-reflow (SF-NR) phenomenon during primary percutaneous coronary intervention (PPCI) than those with single vessel disease. Currently, no effective tools exist to predict the risk of SF-NR in this population. The present study aimed to evaluate whether CHA₂DS₂-VASc score can be used as a simple tool to predict this risk.This study consecutively included STEMI patients hospitalized in Beijing Anzhen Hospital from January 2005 to January 2015. Among these patients, 1032 patients with MVD were finally enrolled. Patients were divided into SF-NR (+) group and SF-NR (–) group according to whether SF-NR occurred during PPCI. SF-NR was defined as the thrombolysis in myocardial infarction (TIMI) grade ≤2.There were 134 patients (13%) in the SF-NR (+) group. Compared with the SF-NR (–) group, patients in the SF-NR (+) group are elder, with lower left ventricular ejection fraction and higher CHA₂DS₂-VASc score. Multiple logistic regression analysis indicated that CHA₂DS₂-VASc score ≥3 (odds ratio [OR], 2.148; 95% confidence interval [CI], 1.389–3.320; P = .001), current smoking (OR, 1.814; 95% CI, 1.19–2.764; P = .006), atrial fibrillation (OR, 2.892; 95% CI, 1.138–7.350; P = .03), complete revascularization (OR, 2.307; 95% CI, 1.202–4.429; P = .01), and total length of stents ≥40 mm (OR, 1.482; 95% CI, 1.011–2.172; P = .04) were independent risk factors of SF-NR. The incidence of SF-NR in patients with CHA₂DS₂-VASc score ≥3 was 1.7 times higher than that in patients with CHA₂DS₂-VASc score <3. Additionally, patients with CHA₂DS₂-VASc score ≥3 plus ≥2 risk factors have 3 times higher incidence of SF-NR than those with CHA₂DS₂-VASc score ≥3 plus 0 to 1 risk factor.CHA₂DS₂-VASc score ≥3 can be used as a simple and sensitive indicator to predict SF-NR phenomenon and guide the PPCI strategy in STEMI patients with MVD.

Standardized nursing and clinical efficacy of OxyContin in reducing oral mucosal pain in patients with nasopharyngeal carcinoma: A randomized,double-blind,placebo-controlled study protocol

Background:Pain caused by oral mucositis (OM) is the main problem in the process of concurrent chemoradiotherapy for the nasopharyngeal carcinoma (NPC). This protocol aims to explore the standardized nursing and therapeutic effect of OxyContin on OM pain in the patients with NPC undergoing the concurrent chemoradiotherapy.Methods:The experiment is a randomized clinical research, which was granted through the Research Ethics Committee of Shandong Provincial Third Hospital (No.20200802097). In this research, 90 NPC patients with OM induced by chemotherapy are enrolled, and the score of visual analogue >5 and the grade of OM >1 are evaluated. Patients with known allergy to OxyContin, the opioid abuse history, or major organ dysfunction, for instance, hepatic insufficiency, renal failure, and respiratory and heart failure, as well as a series of severe mental illness are excluded from our research. Patients in study groups receive standardized nursing and oral OxyContin. Patients in control groups only receive oral OxyContin. The analgesic effect could be assessed with the comparison of the visual analogue scale after and before the treatment. Safety evaluations contain the assessment of the vital signs, laboratory tests, as well as adverse events. The Karnofsky performance status standards of the International Cancer Control Union is utilized to evaluate the quality of life.Results:The comparison of outcomes after taking OxyContin in both groups will be shown in Table ​Table1Table1 .Table 1The comparison of outcomes after taking OxyContin in both groups.

Deciphering principles of morphogenesis from temporal and spatial patterns on the integument

Background : How tissue patterns form in development and regeneration is a fundamental issue remaining to be fully understood. The integument often forms repetitive units in space (periodic patterning) and time (cyclic renewal), such as feathers and hairs. Integument patterns are visible and experimentally manipulatable, helping us reveal pattern formative processes. Variability is seen in regional phenotypic specificities and temporal cycling at different physiological stages. Results: Here we show some cellular/molecular bases revealed by analyzing integument patterns. (1) Localized cellular activity (proliferation, rearrangement, apoptosis, differentiation) transforms prototypic organ primordia into specific shapes. Combinatorial positioning of different localized activity zones generates diverse and complex organ forms. (2) Competitive equilibrium between activators and inhibitors regulates stem cells through cyclic quiescence and activation. Conclusions: Dynamic interactions between stem cells and their adjacent niche regulate regenerative behavior, modulated by multi‐layers of macro‐environmental factors (dermis, body hormone status, and external environment). Genomics studies may reveal how positional information of localized cellular activity is stored. In vivo skin imaging and lineage tracing unveils new insights into stem cell plasticity. Principles of self‐assembly obtained from the integumentary organ model can be applied to help restore damaged patterns during regenerative wound healing and for tissue engineering to rebuild tissues.

A synthesis and performance evaluation of a highly efficient ecological dust depressor based on the sodium lignosulfonate–acrylic acid graft copolymer

In this paper, a highly efficient and environmentally-friendly dust depressor was developed based on the sodium lignosulfonate–acrylic acid graft copolymer. Using the grafting ratio as an index, a three-factor and four-level orthogonal experiment was conducted to optimize the fabrication conditions of the graft copolymer. At a reaction temperature of 60 °C, feed ratio m_SLS–AA of 1 : 3, and FeSO₄·7H₂O content of 2.5%, the prototype produced the highest grafting ratio. The microstructure of the graft copolymer was measured using Fourier transform infrared spectrometry (FTIR) and nuclear magnetic resonance (¹H-NMR). Furthermore, the influence of glycerol and the JFC penetrant on the contact angle between the compound solution and coal powder was investigated. Finally, four formulas of dust depressor were selected based on the experimental results. The dust-control performance of the four dust depressors was then tested on a large-scale spray dust suppression simulation platform. The results show that after applying formula 1 at various distances from the spray field, the average dust reduction rates of the total dust (respirable dust) at each point increased. Compared to the water-spraying dust suppression technique, the dust concentration is significantly reduced after the graft copolymer dust depressor is applied.

In this paper, a highly efficient and environmentally-friendly dust depressor was developed based on the sodium lignosulfonate–acrylic acid graft copolymer.
