This study aimed to explore the mediating effect of perceived social support on the relationship between mindfulness and burnout in Chinese special education teachers. Three hundred and seven teachers completed the Five‐Facet Mindfulness Questionnaire, Multi‐dimensional Scale of Perceived Social Support Scale, and Teacher Burnout Inventory. The results showed that burnout was negatively correlated with mindfulness and perceived social support, while perceived social support was positively correlated with mindfulness. Moreover, perceived social support partially mediated the effect of mindfulness on special education teachers' burnout. These results suggest that the use of mindfulness combined with perceived social support may be beneficial for preventing and mitigating burnout among special education teachers.

The relationship of language style and online review has drawn increasing academic attention recently as it can provide customers with a guide to make the purchase. Extant research attaches importance to the language style that is presented in the use of function words, instead of product-related content words. This study aimed to examine the language style generated by customers’ comments relating to the product based on content words, that is, product-centered language style (PCLS). We built a corpus of Chinese women clothes online reviews to explore the general picture and distinct features of PCLS and the distinct feature of PCLS. A content-word-centered Linguistic Inquiry and Word Count (LIWC) in terms of product performance is established. PCLS is calculated based on the language style matching (LSM) algorithm. Our results show that the PCLS in women clothes online review is featured by diverse and polarized language styles among three groups of women clothes buyers, and the prioritized arrangement of words of importance contributes to the PCLS. The findings benefit the women clothes industry in which it can help companies quickly find the distinctive and the transition of PCLS and offer an approach for companies to indiscriminately look into the significance of the product category from the linguistic perspective, which can help with product sale strategy and product design.

<b><i>Aim:</i></b> This systematic and meta-analysis was conducted to evaluate the efficacy and safety of insulin, metformin, and glyburide on perinatal complications for gestational diabetes mellitus (GDM). <b><i>Methods:</i></b> Medline (PubMed), EMBASE, The Cochrane Library (Cochrane Database of Systematic Reviews, Cochrane Central Register of Controlled Trials [CENTRAL], and Cochrane Methodology Register), Web of Science (Science and Social Science Citation Index), and ClinicalTrials (Clinicaltrials.gov) were searched, as well as manual searching. We included randomized controlled trials comparing efficacy and safety of metformin versus glyburide, metformin versus insulin, and glyburide versus insulin in patients with GDM. <b><i>Results:</i></b> We included 32 articles including 5,964 patients published from inception to July 2020. Compared with insulin, metformin was more effective at lower incidence of macrosomia (RR: 0.66, 95% CI: 0.50–0.88, <i>p</i> = 0.005), lower incidence of neonatal intensive care unit admission (RR: 0.78, 95% CI: 0.67–0.91, <i>p</i> = 0.002), less neonatal hypoglycemia (RR: 0.67, 95% CI: 0.56–0.80, <i>p</i> &#x3c; 0.0001), decreased birth weight (BW) (SMD: −0.37, 95% CI: −0.62 to −0.12, <i>p</i> = 0.004), lower incidence of large for gestational age (RR: 0.76, 95% CI: 0.50–0.90, <i>p</i> = 0.002), shorter gestation age at delivery (MD: −0.22, 95% CI: −0.34 to −0.10, <i>p</i> = 0.0002), lower maternal weight gain (MD: −1.41, 95% CI: −2.28 to −0.55, <i>p</i> = 0.001), less incidence of caesarean section delivery (RR: 0.86, 95% CI: 0.78–0.95, <i>p</i> = 0.0004), lower maternal postprandial blood glucose (SMD: −0.41, 95% CI: −0.72 to −0.11, <i>p</i> = 0.008), and lower incidence of pregnancy-induced hypertension (RR: 0.47, 95% CI: 0.27–0.83, <i>p</i> = 0.01). However, glyburide, compared with insulin, was associated with higher BW (MD: 54.95, 95% CI: 3.87–106.03, <i>p</i> = 0.03) and increased the incidence of neonatal hypoglycemia (RR: 1.52, 95% CI: 1.12–2.07, <i>p</i> = 0.007). Meanwhile, compared to glyburide, metformin was associated with higher maternal fasting blood glucose (SMD: 0.20, 95% CI: 0.05–0.36, <i>p</i> = 0.01) and lower incidence of induction of labor (RR: 0.76, 95% CI: 0.59–0.97, <i>p</i> = 0.03). <b><i>Conclusions:</i></b> This review suggests that metformin can decrease the incidence of perinatal complications, and it should be considered as a generally safe alternative to insulin.
