Objective To investigate the clinical value of serum LDH levels in tsutsugamushi patients. Methods We selected 60 patients with tsutsugamushi disease who were enrolled in our hospital from September 2016 to February 2018,including 25 males and 35 females. We recorded the patients' basic conditions,blood tests,liver and kidney function and other laboratory testing indicators;and we detected serum lactate dehydrogenase levels in patients. The correlations in lactate dehydrogenase and platelet number,alanine aminotransferase,and aspartate aminotransferase were analyzed. Results Most patients developed fever,headache,abdominal pain,cough,sputum,and other symptoms. A small number of patients suffered low back pain,disturbance of consciousness,skin mucosal bleeding,and other symptoms;among the 60 patients with tsutsugamushi disease,the contents of serum amblytic dehydrogenase were higher than normal in 52 patients,and the numbers of platelets in 15 patients were lower than normal. The value of alanine aminotransferase was higher than normal in 55 patients,and the value of aspartate aminotransferase was higher than normal in 53 patients;serum LDH and platelet counts （r=-0.929,P<0.01）,alanine aminotransferase （r=0.957,P<0.01） and aspartate aminotransferase （r=0.947,P<0.01） showed positive correlation. Conclusion Lactate dehydrogenase level may be used as an early diagnostic marker for patients with tsutsugamushi disease.

目的 应用NRS2002、MNA-SF两种营养筛查方法评估住院老年冠心病患者营养风险,观察营养风险与营养指标及心功能的关系。方法 选取2017年8月-2018年6月在我院全科医学科住院的老年冠心病患者129例,使用两种方法分别进行营养筛查,分成存在营养风险组和不存在营养风险组,完善血常规、生化、心功能检查,统计两组各项指标之间的关系,及两种营养筛查方法与各项指标的相关性。结果 NRS2002筛查出营养风险发生率为38.76%,MNA-SF筛查出营养风险发生率75.97%。与不存在营养风险组比较,存在营养风险组的BMI、HB、ALB下降,且NRS-2002评分中存在营养风险组pro-BNP较不存在营养风险组明显升高。两种营养筛查方法与HB、PA、ALB、pro-BNP均有相关性。结论 运用两种营养筛查方法,结合各项指标能更好对老年冠心病患者进行营养风险评估。

Objective To analyze the preoperative nutritional screening results of the nutritional risk screening 2002（NRS2002） and the Mini Nutritional Assessment Short Form（MNA-SF） in 129 elderly patients with coronary heart disease and their relationships with some nutritional indicators and heart function. Methods NRS2002 and MNA-SF were used to evaluate the nutritional risk of 129 elderly patients with coronary heart disease. We divided the patients into nutritional risk group and non- nutritional risk group. The relationships between two groups with the nutritional indicators and the heart function were analyzed,and the value of the two nutritional screening tools was compared. Results The incidence rate of malnutrition by using NRS2002 was 38.76% and that of MNA-SF was 75.97% among 129 CHD patients. The nutritional risk group had lower BMI,HB and ALB. Nutritional risk group that was screened by NRS2002 had higher pro-BNP. And the two nutritional risk texts were related to HB,PA,ALB and pro-BNP. Conclusion It would be better to use two methods and some indicators to analyze the nutritional risk in elderly CHD patients in the hospital.

目的 探讨新生儿高促甲状腺素血症转归与先天性甲状腺功能减低的相关性。方法 选择2014年4月—2015年4月在本院新生儿疾病筛查中心筛查并诊断为高促甲状腺激素血症的患儿120例,期间密切监测甲状腺功能指标变化。结果 将非治疗组所有患儿按照入组该实验后首次抽取静脉血TSH检测水平分为3组:5.5~10.0 mU/L(20例)、10.1~15.0 mU/L(10例)、＞15.0 mU/L (8例)。非治疗组患儿第2次随访结果显示5.5~10.0 mU/L组所有患儿TSH水平<10.0 mU/L;10.1~15.0 mU/L组有1例患儿TSH水平＞10.0 mU/L,FT4水平在正常值上限;＞15.0 mU/L组有3例患儿 TSH水平＞10.0 mU/L,差异有统计学意义(P< 0.05),FT4水平在正常均值左右,差异没有统计学意义(P＞ 0.05),＞15.0 mU/L组3例患儿给予左旋甲状素钠治疗。治疗组有2例患儿分别在治疗15天和23天后出现医源性甲状腺功能亢进,停药和酌减药量后TSH、FT4水平均恢复正常。两组患者随访结束后TSH、TF4均恢复至正常水平。结论 大多数新生儿高促甲状腺素血症会随着年龄的增长恢复正常,而仅仅有少部分患儿会持续出现甲状腺功能异常,应积极随访;新生儿只有当TSH 基础值＞15.00 mU/L时才需要采用左旋甲状素钠替代治疗,并且严格随访甲状腺功能,避免过度治疗。

Objective To explore the correlations between disease activity of inflammatory bowel disease(IBD) and lipid profiles levels by compare the levels of plasma lipids in patients with IBD. Methods A total of 159 IBD patients admitted to Nanhai Hospital of Southern Medical University from January 2013 to May 2018 were included in the study and the clinical data were collected. There were 159 healthy people recruited in the control group. The differences of plasma levels of triglycerides(TG), total cholesterol(TC), low-density lipoprotein cholesterol(LDL-C), high-density lipoprotein cholesterol(HDL-C), lipoprotein(a), albumin and high-sensitivity C-reactive protein(hCRP) between these two groups were analyzed respectively. The relationships between lipids levels and the severity of IBD were analyzed. Results Plasma levels of TG,TC,LDL-C,HDL-C and albumin were lower in IBD group than those in control group,but lipoprotein(a) was higher than control group(P＜0.05). The levels of TC,LDL-C,HDL-C and albumin were lower in CD patients compared to those of UC(P＜0.05). Plasma levels of TC,LDL-C,HDL-C gradually decreased with the severity of IBD. TC,LDL-C,HDL-C values were negatively correlated with hCRP levels in IBD patients. And lipoprotein(a) values was positively correlated with hCRP levels in IBD patient. However, there was no association between TG levels and the severity of IBD. Conclusion TG、TC、LDL-C、HDL-C levels are decreased and lipoprotein(a) is increased in IBD patients, especially CD patients, compared with healthy controls. Moreover, the cholesterol levels are negatively associated with more severe disease activity.

Methods A total of 90 children with allergic purpura who were treated in our hospital from December 2016 to Feb 2018 were randomly selected as observation group. 90 healthy children who were admitted to our hospital for physical examination during the same period were selected as the control group, and the Hp infection in the two groups was compared. According to Hp infection and treatment, the observation group was divided into three groups: A, B and C, among which group A (29 cases) was Hp (-) group, and routine treatment was performed.Group B (31 cases) were Hp (+) group, and routine treatment was performed. group C (30 cases) were Hp (+) group, and conventional treatment combined with anti-hp treatment were performed. We compared three groups of .curative effects. Results The positive rate of Hp infection in the observation group was higher than that in the control group, and the difference was statistically significant (P<0.05).The positive rate of Hp infection in HSP patients with abdominal symptoms was higher than that in HSP patients without abdominal symptoms, and the difference was statistically significant (P<0.05). The effective rate of treatment in group B was significantly lower than that in group A, and the effective rate of treatment in group C was higher than that in group B, and the difference was statistically significant (P<0.05). Conclusion Hp infection may be one of the causes of HSP, and its abdominal symptoms are closely related to Hp, and the eradication of Hp treatment would improve the prognosis of HSP patients.

目的 探讨急性心肌梗死患者入院首次中心粒细胞/淋巴细胞比值(neutrophil/lymphocyte ratio,NLR)与院内主要不良心血管事件(MACE)发生的相关性。方法 回顾分析2016年1月—2016年12月入住我院的急性心肌梗死患者179例,分为发生院内不良事件组(n=46)和未发生组(n=133)。采用单因素及多因素Logistics回归分析评估NLR与MACE风险的相关性。结果 179例患者中,46例患者发生院内MACE。发生院内MACE组患者的淋巴细胞计数低于未发生组(P<0.05),NLR高于未发生组(P<0.05),发生院内MACE组患者入院时的心、肾功能较未发生组差(P<0.05)。单因素回归分析显示,NLR水平与院内MACE发病率相关(OR=1.079,95%CI:1.014～1.147, P＜0.05)。多因素logistic回归分析校正性别、年龄、高血压病史、糖尿病史、Killip II级以上、收缩压、入院首次白细胞、eGFR、超敏C反应蛋白、左室射血分数及多支病变后显示,NLR是院内MACE的独立危险因素(OR=1.182,95%CI:1.034～1.352,P＜0.05);此外,超敏C反应蛋白及LVEF<50也是院内MACE的独立危险因素(P＜0.05)。结论 入院首次高NLR与急性心肌梗死患者发生院内MACE相关,是患者发生院内MACE的独立危险因素。

Objective To explore the correlation between first neutrophil/lymphocyte ratio(NLR) and in-hospital major adverse cardiac events (MACE) in patients with in patients with acute myocardial infarction. Methods Total of 179 patients with acute myocardial infarction in Guangzhou First People's Hospital from Jan 2016 to Dec 2016 were enrolled. MACE was defined as malignant arrhythmia, recurrence of myocardial infarction, target vascular reconstruction, acute left heart failure, stroke, cardiac shock and death.Baseline data and in-hospital clinical adverse events were compared among two groups. All patients were divided into two groups:MACE(+) group and MACE(-) group. Univariate and multivariate logistic regression was used to assess the correlation between NLR and in-hospital MACE. Results In-hospital MACE occurred in 46(25.7%)patients. Univariate logistic analysis showed that NLR was strongly related with MACE incidence(OR=1.079,95%CI:1.014～1.147, P＜0.05). Multivariate logistic regression analysis found that after adjusting other traditional risk factors including female gender, age, hypertension,diabetes, overKillip II grade, systolic blood pressure,first white blood cells after admitted,basic renal dysfunction,Hs-CRP,LVEF and multivessel lesions. NLR was still a significant independent predictor of in-hospital MACE in patients with acute myocardial infarction. Additionally, hs-CRP and LVEF<50% were also associated with in-hospital MACE(P＜0.05). Conclusion NLR is the independent risk factor for in-hospital MACE occurrence in acute myocardial infarction at the early admission.
