肝细胞生长因子对视网膜色素上皮细胞增生及损伤愈合的影响

目的 研究肝细胞生长因子(hepatocyte growth factor，HGF)对培养的人视网膜色素上皮(retinal pigmental epithelial，RPE)细胞增生和损伤愈合的影响。方法 MTT比色法检测细胞增生情况，相差显微和细胞计数法观察RPE细胞损伤后的愈合情况。结果 中等浓度HGF(10ng／ml)刺激RPE细胞的增生较低浓度组(0．01～1ng／m1)明显增多(P＜0．05)，而与高浓度(100ng／ml)组比较无统计学差异(P＞0．05)。随着HGF刺激时间的延长，迁移的细胞数量增多，同一时间点，HGF处理组明显比对照组细胞数量多(P＜0．05)。结论 中等浓度的HGF可促进细胞增生，对损伤后的RPE细胞有迁移作用。

Japanese-Style Diet and Cardiovascular Disease Mortality: A Systematic Review and Meta-Analysis of Prospective Cohort Studies

This systematic review and meta-analysis elucidate the effects of the Japanese-style diet and characteristic Japanese foods on the mortality risk of cardiovascular disease (CVD), cerebrovascular disease (stroke), and heart disease (HD). This review article followed the PRISMA guidelines. A systematic search in PubMed, The Cochrane Library, JDreamIII, and ICHUSHI Web identified prospective cohort studies on Japanese people published till July 2020. The meta-analysis used a random-effects model, and heterogeneity and publication bias were evaluated with I² statistic and Egger’s test, respectively. Based on inclusion criteria, we extracted 58 articles, including 9 on the Japanese-style diet (n = 469,190) and 49 (n = 2,668,238) on characteristic Japanese foods. With higher adherence to the Japanese-style diet, the pooled risk ratios (RRs) for CVD, stroke, heart disease/ischemic heart disease combined (HD/IHD) mortality were 0.83 (95% CI, 0.77–0.89, I² = 58%, Egger’s test: p = 0.625, n = 9 studies), 0.80 (95% CI, 0.69–0.93, I² = 66%, Egger’s test: p = 0.602, n = 6 studies), and 0.81 (95% CI, 0.75–0.88, I² = 0%, Egger’s test: p = 0.544, n = 6 studies), respectively. Increased consumption of vegetables, fruits, fish, green tea, and milk and dairy products decreased the RR for CVD, stroke, or HD mortality. Increased salt consumption elevated the RR for CVD and stroke mortality. Increased consumption of dietary fiber and plant-derived protein decreased the RR for CVD, stroke, and HD/IHD mortality. The Japanese-style diet and characteristic Japanese foods may reduce CVD mortality. Most studies conducted diet surveys between 1980 and the 1990s. This meta-analysis used articles that evaluated the same cohort study by a different method. A new large-scale cohort study matching the current Japanese dietary habits is needed to confirm these findings.     

中医综合疗法治疗脾胃湿热型雄激素源性脱发的临床研究

目的观察中医综合疗法治疗脾胃湿热型雄激素源性脱发的临床疗效。方法将65例脾胃湿热型雄激素源性脱发患者随机分为治疗组(33例)与对照组(32例)。对照组予中药内服及针刺疗法,治疗组同时加用七星针叩刺。两组疗程均为3个月,观察临床疗效,并比较治疗前后临床症状总积分及各分项积分的变化情况。结果 1治疗组、对照组总有效率分别为90.91%、84.38%;组间临床疗效比较,差异有统计学意义(P0.05)。2治疗前后组内比较,两组掉发情况、头皮情况、新发再生情况积分及总积分差异均有统计学意义(P0.05);组间治疗后比较,掉发情况、头皮情况、新发再生情况积分、总积分及其变化差值的差异有统计学意义,治疗组优于对照组(P0.05)。结论中医综合疗法治疗脾胃湿热型雄激素源性脱发的疗效满意,可显著改善患者的临床症状,促进毛发新生。     

Neonatal outcome in discordant eutrophic twins: twin growth.

OBJECTIVE: To compare maternal characteristics and neonatal outcome in discordant twin gestations (DT) and concordant twin gestation (CT). METHOD: Maternal and neonatal data base of live twins >25 weeks' gestation (N=351 pairs) were reviewed for antepartum complications, labor beginning, mode of delivery, neonatal complications, malformations and perinatal mortality. The chi-squared analysis and Student t-tests were used to analyze the differences between discordant and concordant premature and term twin pairs, and appropriate for gestational age (AGA) twins, separately. RESULTS: DT occurred in 15.1% of all twin pregnancies. In preterm and term DT there were significantly more elective cesareans. Growth discordance among preterm and term eutrophic twins was not connected with increased neonatal death or other complications, except higher incidence of early neurological signs in term DT. CONCLUSION: We strongly believed that prematurity and not discordant growth of eutrophic twins has important influence on neonatal outcome.     

Healthy Taiwanese Eating Approach (TEA) toward Total Wellbeing and Healthy Longevity

A healthy dietary pattern review for Asian countries is scarce, which is crucial for guiding healthy eating. We reviewed Taiwanese dietary pattern discovery studies. Included were 19 studies, the majority of which employed dimension reduction methods to find dietary patterns associated with various health conditions. To show what is a high or low intake of foods in Taiwan, we also report the average dietary content and the 25th and 75th percentile values of the adult population for six food groups gathered by the Nutrition and Health Survey in Taiwan, 2017–2020. The healthy Taiwanese dietary approach is cohesive across multiple health outcomes occurring at different ages. It is featured with higher intakes of plant-based foods, aquatic foods, and some beneficial ethnic foods (soy products), drinks (tea), and cooking methods (boiling and steaming); lower intakes of fast foods, fatty and processed meats, sugar, salt rich foods/drinks, and fried foods; but with mixed findings for dairy and egg. Yet, the average Taiwanese person consumed many refined staple foods and livestock, but not sufficient vegetables, fruits, whole grains and roots, beans, and nuts. Dairy consumption remains low. In conclusion, Taiwanese discovery studies point to a mortality-lowering total wellbeing dietary pattern consistent with the current knowledge, which discloses potential benefits of soy product, tea, and boiling and steaming.

强化DHA奶粉对大鼠生长发育的影响

喂给刚断乳的Wistar雄性大鼠含与不含DHA（二十二碳六烯酸，50mg／100g）的奶粉（占80％）组成的饲料共28天。检测了实验期大鼠净增重、食物利用率、净增重与饲料蛋白质比值，血红蛋白、红细胞、白细胞计数，血液中谷丙转氨酶（SGPT）和超氧化物歧化酶（SOD）的活性以及脏体比值。结果表明，强化DHA组的大鼠净增重在第20天时就显著高于未强化组[（111．8±16．9）g与（92．9±17．3）g]，食物利用率和净增重与饲料蛋白质比值也较高，两组间无显著差异。其它指标也无显著差异，但是，强化DHA组大鼠脑与体重比值较高。这些结果表明，强化DHA奶粉能促进大鼠的生长发育。
