Objective To explore the clinical value of echocardiographic evaluation of myocardial injury caused by pulmonary hypertension (PAH) and the correlation of oxidative stress injury. Methods Forty-eight 12-week-old SD rats were collected. They were randomly divided into 4 groups: blank control group, NaCl control group, PAH 2-week group and PAH 4-week group. After modeling, ultrasound was used to detect relevant parameters. HE and Masson staining were used to observe the distribution of myocardial cells and collagen fibers in the right ventricle. Superoxide dismutase (SOD) activity, reduced glutathione (GSH) and malondialdehyde (MDA) levels were measured, and their correlations with ultrasound parameters were evaluated. Results The ultrasound-related parameters of rats in the PAH group changed significantly and gradually increased.HE and Masson staining showed that cardiac myocytes were enlarged and collagen fibers in myocardial interstices were increased, and it was more obvious in the 4-week group.In the PAH group, the SOD activity and GSH levels were lower, while the MDA levels were higher, and there was a trend of change, and there was a significant correlation with ultrasound parameters. The difference was statistically significant (P<0.05). Conclusion PAH causes changes in the myocardial tissue structure of the rat right ventricle, as well as changes in oxidative stress-related indicators.

Method A total of 136 postmenopausal Han women, who were related in the outpatient department, community, and hospital after hospitalization in Shihezi district of Xinjiang province from October 2016 to October 2017, were selected as the study subjects by the inclusion criteria and exclusion criteria.According to the patient's medicalhistory, glucosetolerance test results and bone mineral density (BMD), they were divided into 4 groups: normal glucose tolerance and normal bone mass (group A), normal glucose tolerance and abnormal bone mass (group B), type 2 diabetes and normal bone mass (group C), and type 2 diabetes mellitus and abnormal bone mass (group D). Baseline data such as patient's age, menopause years were measured and recorded, and body mass index (BMI)was calculated. Simultaneously, glucose metabolism indicators including fasting blood glucose (FBG, etc), bone metabolism indicators (blood Ca, etc), lipid metabolism indicators(triglycerides, etc)were detected. The polymorphisms of rs3736228 and rs3781586 of LRP5 gene were determined by Maldi-Tof-Ms and those data were analyzed statistically. Results ①Glucose metabolism index: compared with group A: FPG and HbAlc in group C, group D were all higher than group A (P<0.01). Lipid metabolism index: compared with group A, TG in group B and group D was lower than that in group A (P<0.05). Bone metabolism index: compared with group A, BMD (L1- 4)and BMD (femoral neck)in group B and group D were lower than those in group A (P<0.01). ②The distribution of SNP genotypes at rs3736228, rs3781586 of LRP5 conformsed to the Hardy-Weinberg genetic equilibrium law (P>0.05). The distribution frequency and allele frequency of LRP5 genotypes rs3736228, rs3781586 were compared among the groups. Pearson chi-square test showed no significant difference (P>0.05). ③Rs 3736228 locus of LRP5 gene:in group A, compared with CC (wild type), CT/TT (mutated type)triglyceride (TG)decreased (P<0.05), BMD (L1- 4)decreased (P<0.05). In group C, compared with CC (wild type), CT/TT (mutated type)high-density lipoprotein (HDL-C)increased (P<0.05), phosphorus increased (P<0.05). Rs 3781586 locus of LRP5 gene: in group B, compared with GG (wild type), GT/TT (mutated type)high-density lipoprotein (HDL-C)increased (P<0.05).Conclusion In the Xinjiang Shihezi district among postmenopausal women with type 2 diabetes, rs3736228, rs3781586 loci of LRP5 gene polymorphism may be irrelevant to glucose metabolism, but the mutation of rs3736228 of LRP5 gene locus may be related to lipid metabolism and bone metabolism (TG, HDL-C, BMD, P), and the mutation of rs3781586 may be related to lipid metabolism (HDL-C).

目的 探讨健康儿童的个体因素对超声测量下腔静脉内径的影响。方法 使用超声测量210例健康儿童的下腔静脉呼气末内径及腹主动脉内径,并记录他们的个体特征,包括性别、年龄、身高、体质量、腰围、体表面积等,进行相关与回归分析。结果 年龄、身高、体质量、腰围、体表面积与下腔静脉和腹主动脉内径呈正相关。年龄是女性儿童下腔静脉内径唯一的独立影响因素,身高是男性儿童下腔静脉内径唯一的独立影响因素。无论男性或女性,年龄是儿童腹主动脉内径的独立影响因素,而下腔静脉和腹主动脉内径的比值不受这些个体因素的影响。结论 下腔静脉和腹主动脉内径易受个体因素影响,而它们的比值不易受个体因素影响,可以更好的用于预测儿童的容量特征。

Objective To explore the impact of individual characteristics on inferior vena cava diameter ( IVC ) in healthy children. Methods IVC_max and abdominal aorta (AO) diameters were measured by ultrasound in 210 healthy children. The individual characteristics including gender, age,height,weight, waist circumference of each child were recorded. Then the surface area(BSA) and IVC_max/AO were calculated to discuss the relationship between them with multivariate analysis. Results Age, height, weight,waist circumference, and BSA were positively correlated with IVC_max and AO. Multivariate linear regression showed that age was the only independent variable for IVC_max in female children, height was the only independent variable for IVC_max in male children, and age was the only independent variable for AO in both females and males. IVC_max/AO was not significantly influenced by the subjects' characteristics. Conclusion IVC_max and AO were more susceptible to subjects' characteristics than IVC_max/AO. IVC_max/AO could be a reliable and practical parameter in children as it was independent of age, height, and weight.

Objective To investigate the feasibility of Mycoplasma pneumoniae-simultaneous amplification and testing (MP-SAT)as a monitoring index for children with Mycoplasma pneumoniae pneumonia (MPP). Methods 178 hospitalized children with community-acquired pneumonia (CAP)in our hospital from October 2017 to October 2018 were selected and divided into two groups, namely MPP group (n=80)and non-MPP group (n=98). Serum MP antibody (MP-Ab)and throat swab MP-RNA were detected separately. The MP-Ab test was used as a reference for the analysis of accuracy of MP-SAT for MPP diagnosis. The MPP patients with positive MP-SAT and positive MP-Ab were observed dynamically. The detection rates of MP-SAT and MP-Ab in different treatment time points were compared. The correlation of MP-SAT negative time with clinical recovery time, clinical symptoms, laboratory parameters and chest X-ray was analyzed. Results The ratio of inconsistent MP-SAT and MP-Ab results was 60.00% (48/80)and 19.39% (19/98)in the MPP group and the non-MPP group, respectively. The MP-SAT and MP-Ab were statistically different in terms of specificity and positive predictive value (P<0.05), while no difference was found in the sensitivity and negative predictive value (P>0.05). Both MP-SAT and MP-Ab were positive in 28 cases (35.00%). The positive rate of MP-SAT was decreased with the prolongation of treatment time (P<0.05), meanwhile the positive rate of MP-Ab was increased with the treatment time (P<0.05); the clinical recovery time of 28 cases was (3.11±0.88)weeks, and the MP-SAT negative time was (3.25±0.74)weeks, with no statistical difference (P>0.05). The long-term duration of MP-SAT was characterized by long duration of fever, high consolidation rate of X-ray chest radiograph, high CRP level, high LDH level, high percentage of neutrophils, and low percentage of lymphocytes (P<0.05).

Objective To report a case of herpes simplex virus central nervous system infection in a neonate and to review literatures about this disease, and to improve clinical understanding of this rare disease and reduce misdiagnosis and missed diagnosis. Methods The clinical manifestation,diagnosis and treatment of the patient with herpes simplex virus central nervous system infection were analyzed.The epidemiology,clinical manifestation and key points of diagnosis were summarized from literature review. Results Literature review showed that: neonatal herpes simplex virus central nervous system infection is very rare. The mortality rate is high, and most of the survivors have adverse neurological outcomes. This case is a fourteen days newborn who was admitted to the hospital due to fever for unknown reasons. He was given acyclovir antiviral therapy immediately after admission and achieved good results. Follow-up of 3 months showed no neurological abnormalities. It suggested that early and effective antiviral therapy is a key factor affecting the prognosis. Conclusion Neonatal herpes simplex virus central nervous system infection has no specific clinical manifestations, and this disease is rare.
