目的 探讨四磨汤联合穴位按摩对早产儿喂养不耐受的影响。方法 将165例出现喂养不耐受的早产儿分组,82例于常规治疗基础上予四磨汤加穴位按摩为研究组,另83例予常规治疗为对照组,观察两组早产儿发生呕吐、胃潴留、腹胀等情况,并在喂养2周后作胃泌素和胰岛素的测定。结果 研究组早产儿发生呕吐、腹胀、胃潴留例数及所占比例分别为 12(14.6%) 、13(15.9%) 、18(22.0),发生率低于对照组(P<0.05);研究组早产儿喂养前和喂养后血清胃泌素分别是(250.41±73.76)ng/L 和(308.27±70.67)ng/L,血清胰岛素是(7.63±2.12)ng/L和(9.43±3.13)ng/L,与对照组相比,2周后的血清胃泌素和胰岛素水平增高(P<0.05)。结论 健脾导滞法可减少早产儿呕吐、腹胀、胃潴留等症状的发生,促进血清胃泌素和胰岛素的分泌,减少早产儿的喂养不耐受的发生。

目的 探究血清外泌体对小鼠烫伤伤口愈合的促进作用及机制。方法 选取我院60只NIH小鼠作为研究对象,对其血清中的外泌体进行提取和分离,建立起皮肤烫伤模型。采用血清外泌体进行治疗,评估治疗的效果,观察皮肤组织的病理变化,检测小鼠成纤维细胞增殖和表皮HaCat细胞迁移使用血清外泌体受到的影响。结果 空白对照组和血清外泌体小鼠烫伤创口愈合时间比较,差异有统计学意义(P＜0.05);血清外泌体作用24 h后,不同剂量OD值差异有统计学意义(P＜0.05);10 μL Exo组和PBS组内部不同时间点OD值差异均有统计学意义(P＜0.05);外泌体组和PBS组24 h的HaCat细胞迁移率相比较,差异有统计学意义(P＜0.05)。结论 血清外泌体可以促进小鼠烫伤伤口的愈合,对成纤维细胞的增殖和表皮HaCat细胞的迁移作用也比较显著,可能成为临床治疗烫伤的新手段。

目的 探讨一次不明原因流产与精子DNA损伤的关系。方法 收集有一次不明原因流产史的患者作为实验组,同时以有正常妊娠史的患者为对照组,分别比较两组男方年龄、精子密度、精子活力、精液量和精子DNA断裂指数有无差异。以SPSS 16.0为统计软件,进行独立样本的t检验。结果 两组的精液量、精子密度及活力均无差异,实验组男方年龄小于对照组(P<0.05),但实验组的DFI要高于对照组(P<0.01)。结论 本研究对照组年龄高于实验组,而DFI正好相反。这说明不明原因的自发流产与男方精子DFI密切相关,随着DFI的增加,流产风险增加。

Objective To investigate the relationship between unexplained abortion and sperm DNA damage. Methods Patients with a history of unexplained abortion were enrolled as an experimental group, and patients with a normal pregnancy history were used as a control group. The differences in age, sperm density, sperm motility, semen volume, and sperm DNA break index were compared between the two groups. The independent sample t test was performed using the statistical software of SPSS 16.0. Results There was no significant difference in semen volume, sperm density and motility between the two groups. The age of the male group in the experimental group was lower than that in the control group (P<0.05), but the DFI of the experimental group was higher than that of the control group, and the difference was statistical significance (P<0.01). Conclusion The age of the study control group was higher than that of the experimental group, while DNA fragmentation index DFI was the opposite, which indicated that unexplained spontaneous abortion was closely related to the male sperm DFI, and the risk of miscarriage may increase with the increase of DFI.

Objective To analyze the effects of different treatment methods on blood donors with haematoma(or bruise) after blood donation. Methods 147 blood donors with haematoma(or bruise) after blood donation in our blood station were randomly selected. According to the difference of treatment methods, they were divided into group A (n=66), group B (n=48) and group C (n=33), for the group A of blood donors to carry out cold and hot compress method, for the group B blood donors to implement the potato slice application method, for the group C blood donors to implement the hi-treatment ointment external application method. Results The total effective rate of group B blood donors was higher than that of group A blood donors. The difference was statistically significant (χ²=4.63,P＜0.05). The total clinical effective rate of group C blood donors was higher than that of group A blood donors. There is statistical significance (χ²=13.99,P＜0.05). The total effective rate of donors in group C was higher than that in group B. The difference between the two groups was statistically significant (χ²=3.99,P＜0.05). Conclusion The effect of external application of Hirudoid(Mucopolysaccharide Polysulfate Cream) on blood donors after blood donation is effective, which may improve their physical and mental health.

Objective To investigate the effect of microsurgery on the operation and symptom improvement of patients with para-sagittal sinus meningioma in functional area. Methods From May 2015 to May 2018, 40 patients with parasickle meningioma of sagittal sinus in our hospital were randomly divided into two groups: control group (n = 20) and study group (n = 20). The patients in the control group were treated with conventional operation, and the patients in the study group were treated with microscope. Results The volume of blood transfusion and the total resection rate of tumor in the study group were lower than those in the control group, and the duration of hospitalization and operation were shorter than those in the control group. Compared with the control group, the incidence of symptom improvement in the study group was higher (95.00% vs 60.00%), the incidence of symptom exacerbation was lower (0.00% vs 35.00%), the difference was statistically significant (P< 0. 05). Conclusion Microscopy may effectively reduce the amount of blood transfusion, shorten the operation time, improve clinical symptoms and promote postoperative recovery in patients with parasagittal sinus meningioma.
