Development of sensory integration therapy in Mainland China: A comprehensive study with bibliometrics and visualization techniques.

Sensory integration therapy (SIT) is an intervention to improve the developmental and learning problems in children. It was introduced in China from late 1980 s to early 1990 s and has received considerable attention from scholars. However, due to its late development in China and its specialised nature, it is worth exploring in depth whether it is recognized by the general public and how it is researched by academics. Therefore, we used Internet survey approach to explore the actual feedback of users towards SIT through the Internet. At the same time, bibliometric method and visualization techniques were used to study 892 journal articles on SIT in CNKI, Wanfang Database and VIP Database to analyze the spatial and temporal distribution, subject distribution, keyword co-occurrence, and keyword clustering of SIT research in mainland China since it came to China mainland. We found that the research on SIT in mainland China has been fruitful. However, the public is less aware of its basic function, therapeutic effects, and necessity. Our findings point to the need to raise awareness of sensory integration disorder and sensory integration therapy among the general public, and to strengthen academic research on sensory integration therapy.

The efficacy and safety of omega-3 fatty acids on depressive symptoms in perinatal women: a meta-analysis of randomized placebo-controlled trials.

Omega-3 fatty acids (FA), as a nutrient, has been proven effective in major depressive disorder (MDD), however, the results of monotherapy in perinatal depression (PND) remain unclear. To examine the efficacy and safety of omega-3 fatty acids (FA) monotherapy for perinatal depression (PND) compared with placebo. PubMed, Embase, PsycINFO, MEDLINE, Cochrane Library, and CINAHL were searched from inception up to November 2019. The reference lists of relevant review articles and included studies were also reviewed. Randomized placebo-controlled trials examining the efficacy and safety of omega-3 FA monotherapy in perinatal women with depressive symptoms were included. Pooled standard mean differences (SMD) were calculated and random-effects models were adopted for all analyses. Subgroups analyses and meta-regression were performed to quantify characteristics of the subjects and trials influencing the omega-3 response. In addition, meta-regression was conducted to identify the source of heterogeneity. The study protocol was registered at PROSPERO, CRD42020159542. Eight eligible randomized placebo-controlled trials were included involving 638 participants. There was a significant effect of omega-3 FA on perinatal depression. Omega-3 with higher ratio of EPA/DHA (≥1.5) had significant efficacy both in mild-to-moderate pregnant and postpartum depression with low incidence of side effects. Among the included trials reporting adverse effects, there was no significant difference in incidence of gastrointestinal and neurologic events between the omega-3 and placebo groups. There was no evidence of publication bias. Our findings suggested that omega-3 FA significantly improved depressive symptoms in perinatal women regardless of pregnant or postpartum and well-tolerated. Furthermore, the omega-3 response was linked to higher EPA proportion in omega-3 formula and mild- to-moderate depression.

Effects of the selective sigma receptor ligand, 1-(2-phenethyl)piperidine oxalate (AC927), on the behavioral and toxic effects of cocaine.

BACKGROUND: Sigma receptors represent a unique structural class of proteins and they have become increasingly studied as viable medication development targets for neurological and psychiatric disorders, including drug abuse. Earlier studies have shown that cocaine and many other abused substances interact with sigma receptors and that antagonism of these proteins can mitigate their actions. METHODS: In the present study, AC927 (1-(2-phenethyl)piperidine oxalate), a selective sigma receptor ligand, was tested against the behavioral and toxic effects of cocaine in laboratory animals. RESULTS: Acute administration of AC927 in male, Swiss Webster mice significantly attenuated cocaine-induced convulsions, lethality, and locomotor activity, at doses that alone had no significant effects on behavior. Subchronic administration of AC927 also attenuated cocaine-induced conditioned place preference in mice, at doses that alone had no effects on place conditioning. In drug discrimination studies in male, Sprague-Dawley rats, AC927 partially substituted for the discriminative stimulus effects of cocaine. When it was administered with cocaine, AC927 shifted the cocaine dose-response curve to the left, suggesting an enhancement of the discriminative stimulus effects of cocaine. In non-human primates, AC927 was self-administered, maintaining responding that was intermediate between contingent saline and a maintenance dose of cocaine. CONCLUSION: The ability of AC927 to elicit some cocaine-like appetitive properties and to also reduce many cocaine-induced behaviors suggests that it is a promising lead for the development of a medication to treat cocaine abuse.

[Effects of Astragalus injection on renal tubular function in patients with IgA nephropathy].

OBJECTIVE: To investigate the relationship between the renal tubular function and the severity of tubulo interstitial lesion and the effects of Astragalus Injection (AI) on renal tubular function in patients with IgA nephropathy (IgAN). METHODS: Sixty-seven patients with IgAN were randomly divided into the control group and the astragalus group, both received dipyridamole and benazepril orally, while the astragalus group treated with AI by intravenous dripping additionally. The indices for renal tubular function, including protein in blood and urine, urinary retinol binding protein (RBP) and N-acetyl-beta-D-glucosaminidase (UNAG), were detected. Area of glomerular Bowman capsule, renal tubules, and capillary were measured with color magic image analysis system type CMIAS2000. RESULTS: Urinary RBP and UNAG were correlated with tubulointerstitial lesion. Urine protein concentration decreased, blood albumin increased remarkably and renal tubular function improved after treatment in the astragalus group, with the improvement significantly different to those in the control group respectively. CONCLUSION: The severity of tubulointerstitial lesion was positively related to urinary RBP concentration, and astragalus injection has obvious effect on IgAN.

Inhibitory effects of alpha-zearalenol on angiotensin II-induced integrin beta3 mRNA via suppression of nuclear factor-kappaB.

OBJECTIVE: To investigate the effect of alpha-zearalenol on angiotensin II-induced beta3 integrin mRNA expression in human umbilical vein endothelial cells (HUVECs). METHODS: The mRNA level in integrin beta3 was determined by reverse transcription-polymerase chain reaction. Endothelial NF-kappaB activity was determined by the luciferase activity assay of plasmid NF-kappaB-LUC. RESULTS: The angiotensin II-induced beta3 integrin mRNA expression was inhibited by alpha-zearalenol and 17beta-estradiol (10 nmol/L -1 micromol/L), but not influenced by ICI 182, 780, a pure competitive antagonist for estrogen receptor or a nitric oxide inhibitor Nomega-Nitro-L-arginine methyl ester hydrochloride. Alpha-zearalenol and 17beta-estradiol suppressed the angiotensin II-induced activation of NF-kappaB in endothelial cells. CONCLUSION: Alpha-zearalenol inhibits angiotensin II-induced integrin beta3 mRNA expression by suppressing NF-kappaB activation in endothelial cells.
