目的探讨区域性静脉灌注葡萄糖酸钙治疗手指氢氟酸烧伤的临床疗效和安全性。方法 2018年5月至2022年6月，浙江衢化医院烧伤与创面修复科收治符合纳入与排除标准的手指氢氟酸烧伤患者40例。收集患者一般临床资料，包括受伤手指分布、创面面积及深度、致伤氢氟酸质量分数、持续接触氢氟酸时间以及院前时间。患者均采用区域性静脉灌注葡萄糖酸钙治疗，灌注液为100 g/L葡萄糖酸钙溶液15 ml、生理盐水35 ml及肝素钠0.1 ml。创面彻底清创，拔除受累指甲，每天1次常规换药。记录患者入院时血清总钙、游离钙、血清钾、血清镁、血氟、尿氟和心电图情况。采用视觉模拟评分法(VAS)评估患者灌注前、灌注后即刻、灌注后4 h以及灌注后24 h疼痛程度。统计患者灌注后4、12及24 h血清总钙、游离钙、尿氟及灌注后24 h血氟水平。统计灌注过程中及灌注结束后24 h内发生的不良反应，以及烧伤创面愈合情况。结果 (1)本组患者中男32例，女8例，年龄主要集中在30～50岁(24例)，所在企业以非氟化工企业为主，单手烧伤35例，双手烧伤5例，共累及83指，烧伤总面积均<1%总体表面积(TBSA)，烧伤深度为Ⅱ～Ⅳ度，其中以Ⅱ度为主(30例)。仅有18例患者致伤氢氟酸质量分数已知，持续接触氢氟酸时间为30.0(14.3，48.8)min，院前时间为9.0(3.3，19.0)h。(2)患者均经单次区域性静脉灌注葡萄糖酸钙治疗后，疼痛明显缓解。灌注前、灌注后即刻、灌注后4 h、灌注后24 h之间比较，疼痛评分呈进行性下降(P<0.01)。(3)患者入院时，以游离钙为参考有11例低钙血症，另外有5例低钾血症。与入院时比较，灌注后4 h血清总钙水平明显升高(P<0.05)；与灌注后4 h比较，灌注后12、24 h血清总钙水平明显下降(P<0.01)。与入院时比较，灌注后4 h游离钙水平明显升高(P<0.01)；灌注后4、12、24 h之间比较，游离钙水平逐渐下降(P<0.01)。(4)患者入院时，有15例血氟高于正常值，尿氟均高于正常值。与入院时比较，灌注后24 h血氟水平明显下降(P<0.01)；入院时及灌注后4、12、24 h之间比较，尿氟水平逐渐下降(P<0.01)。(5)所有患者在灌注过程中及灌注结束后24 h内，未发生不良反应。创面愈合时间为4.0～30.0(11.1±5.9)d，35例经换药治疗创面愈合，5例通过手术治疗后愈合。结论即使手指氢氟酸烧伤总面积<1%TBSA，伤后患者血氟、尿氟水平仍可升高数十倍，并伴有电解质紊乱。采用区域性静脉灌注葡萄糖酸钙治疗手指氢氟酸烧伤，临床疗效显著，操作简单且安全性高，可以明显减轻疼痛，有效阻断氟离子进行性损害。

Water intake, hydration status and related hydration biomarkers among young male athletes in Beijing, China: a cross-sectional sur-vey

中国营养学会第十五届全国营养科学大会

作者： Na zhang jianfen zhang Yibin Li Xing Wang Guansheng Ma School of Public Health Peking University

The objective of this study was to determine the energy expenditure, sources, and loss of water among young adults. Methods n this cross-sectional study, 25 young adults aged 18-23 years were recruited. The method of double-labeled water was used to determine the energy expenditure of participants. Then, water loss through skin evaporation and respiration of the lungs and water sources from metabolic water were calculated using a corresponding formula, respectively. Water loss through excretion of urine was recorded and evaluated using the method of a "3-day, 24-hour, real-time urine excretion record". All the random urine samples were collected and weighed in the 3 days. Water loss through excretion of feces was evaluated using a "3-day, 24-hour, real-time fecal-excretion record". All fecal samples were collected and tested by the direct drying method in the 3 days. Water sources from fluid intake were recorded by a "7-day, 24-hour, real-time fluid intake record"(***7). Water intake from food was calculated and tested by the weighing method combined with the duplicate portion method and the direct drying method in the 3 days. Results The energy expenditure of male participants was 2187 kcal/d, and that of females was 1987 kcal/d. The median fluid intake, water intake from food, and metabolic water were 887 mL, 1173 mL, and 246 mL, respectively, which accounted for 38.8%, 50.3%, and 11.2% of total water sources. There was a gender difference in the percentage of metabolic water(Z=-2.135, P=0.033). The water loss through urine excretion, skin evaporation, respiration, and feces excretion was 1295 mL, 172 mL, 149 mL, and 64 mL, respectively, which accounted for 76.5%, 10.3%, 9.5%, and 3.6% of the total water losses. Gender differences in the amount of water loss through respiration and skin evaporation were found(Z=-4.125, P<0.001;Z=-3.723, P<0.001). Conclusion More studies should be carried out to determine the energy expenditure, sources, and loss of water among

Studies on the water intake behaviors of athletes in daily life are insufficient. The objectives of this study were to determine the water intake and hydration status among athletes and to analyze their relationships between water intake and related biomarkers. Methods In this cross-sectional study, 111 young male adult athletes aged 18-23 years were recruited in one university in Beijing, China. The amount and type of daily total drinking fluid intake among participants was recorded and evaluated in real time over 7 days using the "7-day 24-hour fluid intake questionnaire"(liq. In7). The daily water intake from food was calculated using the weighing method, duplicate portion method and direct-drying method over 3 days. All the urine samples over 3 days were also collected, and the related urine biomarkers were determined. According to 24-h urine osmolality, the participants were divided into three groups with optimal hydration, middle hydration and hypohydration statuses. Results Finally, 109 participants completed the study. The median daily total water intake, total drinking fluid intake and water intake from food were 2701 mL, 1789 mL and 955 mL, respectively. Among participants, 17 participants(16%) were in optimal hydration, 47 participants(43%) were in hypohydration, and 45 participants(41%) were in middle hydration. There were statistical significances in the 24-h urine volume, osmolality, urine specific gravity, and concentrations of K, Na and Cl in different hydration statuses(c2=28.212, P<0.01;c2=91.341, P<0.01;c2=47.721, P<0.01;c2=41.548, P<0.01;c2=46.863, P<0.01;c2=40.839, P<0.01). Moderate-intensity correlations were found between the total drinking fluid intake and 24-h urine volume, 24-h urine osmolality, 24-h urine Na concentration, morning urine osmolality, and morning urine Na concentration(r=0.408, P<0.01;r=-0.378, P<0.01;r=-0.325, P<0.01;r=-0.344, P<0.01;r=-0.329, P<0.01).

水是人类生存和发展所必需的物质,参与多种生理功能。水的3个来源和4个去路维持着身体水的动态平衡。饮水是身体获取水分的最主要来源,通过肾脏排出的尿液是身体排出水分的最主要去路。饮水行为包括水摄入量和饮水类型的选择。笔者从饮水行为、排尿行为对水合状态和健康的影响进行了分析,发现中国关于饮水和排尿行为的研究尚未引起足够重视,有必要开展更多饮水和排尿行为调查,研究其与健康的关系,可为修订中国居民水适宜摄入量提供科学数据,促进中国居民形成健康饮水和排尿行为,维持适宜水合状态,最终促进身体健康。

为缓解桑椹难以储藏的问题,丰富红茶菌功能饮料种类,以新鲜桑椹、茶糖水为主要原料,通过红茶菌发酵研制桑椹红茶菌功能饮料。发酵饮料兼具浓郁果香和清新茶香,口感酸甜适宜,色泽鲜亮,感官评分为90.2分。25℃发酵12 d,制备的桑椹红茶菌发酵饮料菌体浓度低,还原糖质量浓度为3.04 mg/mL,pH为2.65,总酸质量浓度为22.8 mg/L。发酵12 d时总多酚、总黄酮和花色苷含量趋于稳定。抗氧化活性研究表明,桑椹红茶菌饮料对DPPH自由基、ABTS自由基和·OH自由基的清除活性较好,且具有一定的还原力。抑菌活性试验表明,发酵12 d时其对金黄色葡萄球菌、枯草芽孢杆菌的抑菌圈直径分别达到(1.34±0.05)cm和(1.35±0.14)cm。体外酶抑制试验表明,发酵12 d时其对α-葡萄糖苷酶抑制活性达到60.6%,对脂肪酶抑制活性达到82.2%。该结果可为桑椹红茶菌发酵功能饮料的开发提供理论依据。

目的探讨重复经颅磁刺激对产后抑郁患者泌乳量的影响。方法选取2016年1～12月在我院分娩的68例患有产后抑郁的产妇作为研究对象,随机分为观察组(n=34)和对照组(n=34)。在常规抗抑郁药治疗基础上观察组使用重复高频经颅磁刺激,对照组使用不引起大脑皮层神经细胞去极化的伪线圈进行刺激。刺激部位:左侧前额叶背外侧区。比较两组治疗后的疗效及泌乳量。结果观察组患者治疗后总有效率(97.1%)显著高于对照组(73.5%),差异有统计学意义(χ~2=5.7448,P=0.0165);观察组较对照组能够显著改善兴趣缺乏及睡眠情况,而对消极情绪、负罪感、焦虑没有明显的改善作用。治疗后观察组患者泌乳量显著多于对照组,差异有统计学意义(P<0.05)。结论重复经颅磁刺激治疗产后抑郁症疗效确切,显著增加患者泌乳量,有利于母婴身心健康。
