目的 分析人类疱疹病毒(EBV)致传染性单核细胞增多症(IM)患儿病毒量与临床特征的关系。方法 选取我院2016年1月—2021年1月收治的EBV定量阳性的IM患儿128例,按照患儿EBV含量分为低病毒量组(n=64)和高病毒量组(n=64)。比较不同病毒含量组患儿的症状体征、实验室检查及临床特征,并分析具有统计学差异的指标与病毒量之间的相关性。结果 高EBV含量组患儿丙氨酸氨基转移酶、乳酸脱氢酶、血沉、外周血白细胞计数指标水平均高于低EBV含量组(P<0.05)。患儿的退热时间、淋巴结缩小时间、肝脾肿大消退时间及住院时间均随着EBV含量的增加而延长(P<0.05)。EBV含量与退热时间、淋巴结缩小时间、肝脾肿大消退时间及住院时间成正相关(r=0.453,0.458,0.402,0.415,P<0.05)。结论 EBV含量越高,IM患儿住院时间及临床指标恢复时间越长,因此临床治疗IM患儿时可以根据EBV含量的高低进行病情评估。

Objective To analyze the relationship between viral load and clinical characteristics in children with infectious mononucleosis (IM) caused by Epstein-Barr virus (EBV). Methods A total of 128 children with IM who tested positive for EBV and admitted to our hospital from January 2016 to January 2021 were selected and divided into low virus group (n=64) and high virus group (n=64) according to their EBV level. The symptoms and signs, laboratory examinations and clinical characteristics of two groups were compared, and the correlation between the statistically different indicators and the amount of virus were analyzed. Results In children with high EBV level, the levels of alanine aminotransferase, lactate dehydrogenase, erythrocyte sedimentation rate, and peripheral blood white blood cell count were higher than low EBV level group (P<0.05). The time of fever, lymph node shrinkage, hepatosplenomegaly to subside, and hospitalization time of the children were all prolonged with the increase of EBV level (P<0.05). The level of EBV was positively correlated with the time to allay fever, the time to shrink the lymph nodes, the time to improve hepatosplenomegaly, and the length of hospital stay (r=0.453, 0.458, 0.402, 0.415,P<0.05). Conclusions The higher EBV level, the longer hospitalization time and recovery time of clinical indicators in children with IM. Therefore, the disease assessment of children with IM can be based on EBV level.

目的 探讨急性脑出血并发高钠血症的原因及预后情况。方法 选择2017年1月—2018年8月就诊于我院的急性脑出血并发高钠血症60例为观察组[根据血清钠离子浓度分为重度组37例（血清钠离子浓度>170 mmol/L）,中度组12例（钠离子浓度161~170 mmol/L）,轻度组11例（钠离子浓度145~160 mmol/L）],选择同期就诊于我院不伴高钠血症的脑出血患者60例为对照组。比较两组意识障碍程度、出血部位、死亡率,并分析急性脑出血并发高钠血症患者中不同血清钠离子浓度患者预后情况。结果 观察组GCS评分≤8分比例、丘脑出血比例、死亡率高于对照组,差异有统计学意义（P<0.05）;观察组基底节区、脑干小脑、脑叶出血比例与对照组比较,差异无统计学意义（P>0.05）;血清钠离子浓度越高则患者的预后越差,差异有统计学意义（P<0.05）。结论 与急性脑出血患者相比,急性脑出血患者并发高钠血症患者的死亡率较高,且预后情况与血清钠离子浓度密切相关;丘脑部出血与急性脑出血患者并发高钠血症密切相关,临床应加以重视。

目的 探讨二甲双胍和胰高糖素样多肽-1对2型糖尿病患者并发骨折恢复的影响。方法 选取2016年5月—2017年4月我院骨科收治的2型糖尿病并发骨折患者120例,按随机原则分为5组,每组24例,单药低剂量二甲双胍组(A1)、单药高剂量二甲双胍组(A2)、单药GLP-1组(B)、低剂量二甲双胍联合GLP-1组(C1)和高剂量二甲双胍联合GLP-1组(C2)。二甲双胍低剂量用药量为0.5 g/次,每日2次口服,高剂量用药量为0.5 g/次,每日4次口服。皮下注射利拉鲁肽每日1次,起始量为每日0.6 mg,1周增加为每日1.2 mg,再1周后增加为每日1.8 mg。血糖控制在理想水平后按照标准的手术方法和规程行相应的手术治疗。同时给予饮食控制及其它对症治疗。分别在1、3、6个月时检测其股骨颈骨密度值(BMD)和Harris系统评分。结果 随着治疗时间延长,A1组、C1组、C2组BMD值和Harris系统评分均增高, 在术后3月和6月时,C1组骨密度值和Harris评分高于A1组(P<0.05), C1组骨密度值和Harris评分高于C2组(P<0.05)。结论 胰高糖素样多肽-1可促进2型糖尿病患者骨折愈合、功能恢复,且与低剂量二甲双胍联用促进骨折愈合效果优于与高剂量二甲双胍联用。

Objective To investigate the effects of metformin and glucagon like polypeptide -1 on fracture recovery in patients with type 2 diabetes mellitus(DM). Methods We selected 120 patients with type 2 diabetes mellitus from May 2016 to April 2017 in department of orthopedicsin in our hospital and randomly divided them into 5 groups, 24 cases in each group,includingthe low dose of metformin monotherapy group (A1), the high dose of metformin monotherapy group (A2), single drug GLP-1 group (B), and GLP-1 group low dose of metformin combination (C1) and high dose of metformin combination with GLP-1 group (C2). The low dose of metformin was 0.5 g / time, 2 times a day for oral administration. The high dose was 0.5 g / time, 4 times a day. Subcutaneous injection of liraglutide was once daily, starting at a daily dose of 0.6 mg, 1.2 mg daily after 1 week and 1.8 mg daily after another week. After an ideal level of blood glucose control, corresponding surgical procedures should be performed according to standard surgical methods and procedures. Diet control and other symptomatic treatments were also given. The femoral neck bone mineral density (BMD) and the Harris system score were examined at the first, third, and sixth month respectively. Results With the prolongation of treatment time, the BMD value and Harris system score in the A1 group, C1 group, C2 group were increased. After surgery in March and June, the BMD and Harris score of C1 group were higher than that of A1 group (P<0.05). The bone mineral density and Harris score of C1 group was significantly higher than that of group C2 (P<0.05). Conclusion Glucagon like peptide -1 may promote the fracture recovery and functional recovery in patients with type 2 diabetes mellitus, and with combination of low dose metformin is more effective than that with high dose metformin.
