Predictors of acute intracranial hemorrhage and recurrence of chronic subdural hematoma following burr hole drainage.

BACKGROUND: To investigate predictors of postoperative acute intracranial hemorrhage (AIH) and recurrence of chronic subdural hematoma (CSDH) after burr hole drainage. METHODS: A multicenter retrospective study of patients who underwent burr hole drainage for CSDH between January 2013 and March 2019. RESULTS: A total of 448 CSDH patients were enrolled in the study. CSDH recurrence occurred in 60 patients, with a recurrence rate of 13.4%. The mean time interval between initial burr hole drainage and recurrence was 40.8 ± 28.3 days. Postoperative AIH developed in 23 patients, with an incidence of 5.1%. The mean time interval between initial burr hole drainage and postoperative AIH was 4.7 ± 2.9 days. Bilateral hematoma, hyperdense hematoma and anticoagulant drug use were independent predictors of recurrence in the multiple logistic regression analyses. Preoperative headache was an independent risk factor of postoperative AIH in the multiple logistic regression analyses, however, intraoperative irrigation reduced the incidence of postoperative AIH. CONCLUSIONS: This study found that bilateral hematoma, hyperdense hematoma and anticoagulant drug use were independently associated with CSDH recurrence. Clinical presentation of headache was the strongest predictor of postoperative AIH, and intraoperative irrigation decreased the incidence of postoperative AIH.

Role of BCL2L10 in regulating buffalo (Bubalus bubalis) oocyte maturation.

It has been reported that BCL2L10 is abundantly and specifically expressed in adult human and mouse oocytes and played a very important role in oocytes maturation and early embryonic development. This study is to investigate the expression pattern of BCL2L10 in buffalo ovaries and its effect on the in vitro maturation of buffalo oocytes, so as to dissect mechanism of oocytes maturation and provide theoretical guidance for improvement of the in vitro maturation of buffalo oocytes. The results showed that BCL2L10 gene was enriched in ovary and the expression of BCL2L10 was oocyte specific and up-regulated during oocyte maturation. BCL2L10 protein and mRNA were detectable in buffalo early embryos, upregulated at 2-cell to 8-cell stages and down-regulated in the later stages. Knockdown of BCL2L10 by RNA interference resulted in a significant decrease in the maturation rate (33.5%) and cleavage rate (37.52%) of buffalo oocytes coupled with up-regulation of apoptosis-related gene Caspase-9. We concluded that BCL2L10 is a candidate associated with buffalo oocyte maturation.

Spermatogenesis-associated proteins at different developmental stages of buffalo testicular seminiferous tubules identified by comparative proteomic analysis.

The testicular seminiferous tubules contain Sertoli cells and different types of spermatogenic cells. They provide the microenvironment for spermatogenesis, but the precise molecular mechanism of spermatogenesis is still not well known. Here, we have employed tandem mass tag coupled to LC-MS/MS with the high-throughput quantitative proteomics technology to explore the protein expression from buffalo testicular seminiferous tubules at three different developmental stages (prepuberty, puberty, and postpuberty). The results show 304 differentially expressed proteins with a ≥2-fold change, and bioinformatics analysis indicates that 27 of these may be associated with spermatogenesis. Expression patterns of seven selected proteins were verified via Western blot and quantitative RT-PCR analysis, and further cellular localizations of these proteins by immunohistochemical or immunofluorescence analysis. Taken together, the results provide potential molecular markers of spermatogenesis and provide a rich resource for further studies on male reproduction regulation.

Analysis of α-lactalbumin-, ß-lactoglobulin-, and casein-specific IgE among children with atopic diseases in a tertiary medical center in Northern Taiwan.

BACKGROUND: Cow's milk allergy is the first manifestation of the allergic march, because cow's milk proteins are the first foreign proteins consumed in large quantities by infants. The aim of this study was to determine which of these proteins causes the greatest sensitization in Taiwanese individuals, and its correlation with atopic patients. METHODS: We retrospectively reviewed the medical records of atopic patients who were treated at the National Taiwan University Hospital from January 2009 to March 2011. A total of 190 patients were enrolled and tested for isolated cow's milk protein (α-lactalbumin, ß-lactoglobulin, and casein) sensitization. These patients were further divided into atopic dermatitis and non-atopic dermatitis subgroups, and also grouped by age. Differences in sensitization to cow's milk proteins between groups were analyzed using the non-parametric Mann-Whitney U-test. RESULTS: The sensitization rate to α-lactalbumin-specific IgE was 60%, followed by ß-lactoglobulin (46.84%) and casein (40.53%). The levels of specific IgE antibodies against α-lactalbumin, ß-lactoglobulin, and casein were higher in patients with atopic dermatitis (1.8, 1.19, 0.95 vs. 0.77, 0.55, 0.40 kUA/L). The younger age group had higher mean specific IgE antibodies against cow's milk proteins than the older age groups. CONCLUSION: There was a different distribution of cow's milk protein sensitization in Taiwanese patients in our study, with α-lactalbumin being most common as compared to casein in Western countries. Among the patients with cow's milk sensitization, the atopic dermatitis group had significantly higher cow's milk protein-specific IgE antibodies as compared to the non-atopic dermatitis group.

Measuring behavioral regulation in four societies.

The present study examined the psychometric properties of scores from a direct measure of behavioral regulation, the Head-Toes-Knees-Shoulders task (HTKS) with 3- to 6-year-old children in the United States, Taiwan, South Korea, and China. Specifically, we investigated (a) the nature and variability of HTKS scores, including relations to teacher-rated classroom behavioral regulation; and (b) relations between the HTKS and early mathematics, vocabulary, and literacy skills. Higher HTKS scores were significantly related to higher teacher ratings of classroom behavioral regulation in the United States and South Korea but not in Taiwan and China. Also, higher HTKS scores were significantly related to higher early mathematics, vocabulary, and literacy skills beyond the influence of demographic variables and teacher-rated classroom behavioral regulation. These initial findings suggest that HTKS scores may be interpreted as reflecting early behavioral regulation in these 4 societies and that behavioral regulation is important for early academic success in the United States and in Asian countries.

Marital enqing: an examination of its relationship to spousal contributions, sacrifices, and family stress in Chinese marriages.

The purpose of this study was to extend understanding of Chinese couples' enqing, a culturally specific component of marital affection that involves the expression of feelings of gratitude and admiration toward one's spouse. In this study, the authors examined family stress, spousal contributions, and sacrifices to study their possible effects on enqing in Chinese marriages. Participants were 455 married people living in northern Taiwan. Overall, the results highlighted the importance of spousal contributions and sacrifices in the development of marital enqing. Additionally, the results indicated that family stress moderated the spousal economic contribution--enqing relationship and the spousal sacrifices--enqing relationship for wives, but not for husbands.
