Association of Mycoplasma pneumoniae coinfection with adenovirus pneumonia severity in children

Between the winter of 2018 and the end of 2019, there has been an epidemic of adenovirus infection in southern China, including Zhejiang Province. The number of children suffering from adenovirus pneumonia (AP) has significantly increased. AP can be accompanied by Mycoplasma pneumoniae in children. This study aimed to investigate the association of M. pneumoniae and identify the risk factors for coinfection on hospitalized patients with AP. The patients were classified into two groups by etiologic analysis (single AP and AP with M. pneumoniae coinfection groups). The clinical manifestations, clinical medication, and laboratory and imaging findings of the two groups were compared and analyzed. The coinfection group (n = 125) had a significantly longer duration of fever than the single AP group (n = 171; P = 0.03). Shortness of breath (P = 0.023) and pulmonary imaging findings, such as pulmonary consolidation, atelectasis, pleural effusion, and multilobe lesions (P < 0.05), were more common in the coinfection group. The patients with coinfection had more severe symptoms, significantly longer hospitalization time and an increased proportion of using glucocorticoids and/or immunoglobulin needing oxygen inhalation (P < 0.05). The incidence of AP with M. pneumoniae coinfection is high. The prolonged fever duration and pulmonary imaging findings could be used as prediction factors to predict M. pneumoniae coinfection in children with AP. Patients with AP coinfected with MP may easily develop severe illness. Hence, a reasonable change in the treatment is necessary (AU)

Correlation between cytokine gene polymorphism and aGVHD in allo-HSCT recipients / 中国免疫学杂志

Objective:To investigate the relationship between gene polymorphisms of disease-relevant multiple cytokines including TNF-α,IL-6,IL-10,TGF-β1,IFN-γand acute graft versus host disease(aGVHD) in allogeneic hematopoietic stem cell trans-plantation ( allo-HSCT ) . Methods:32 cases of recipients received allo-HSCT and 36 cases of normal groups in January 2014 to December 2015 were selected as objects of study. We detected genotypes on specific SNP of target genes by polymerase chain reation ( PCR) combined with gene sequencing and observed the occurrence of aGVHD in postoperative recipients. The influence of cytokine gene polymorphisms on prognosis of allo-HSCT patients was analyzed,and the potential relationship between specific SNP mutation of the disease-relevant cytokine genes and severity of aGVHD was discussed. Results:Distribution of cytokines gene polymorphism including TNF-α-308(G/A),IL-6-174(G/C),IL-10-1082(A/G),TGF-β1+915(G/C),IFN-γ(T/A) had no significant differences with incidence of severe aGVHD(P>0. 05). However,the occurrence of severe aGVHD in allo-HSCT recipients with C/T genotype was significantly higher than C/C and T/T in SNP of TGF-β1+869(P<0. 01). Conclusion:Gene polymorphism of TGF-β1+869(C/T) in allo-HSCT patients was closely related to the occurrence of severe aGVHD. The research show allo-HSCT patients with C/T genotype occurred severe aGVHD more frequently, which is an important potential risk factor to induce the incidence of severe aGVHD. Therefore,detecting gene polymorphism of TGF-β1+869 ( C/T ) in allo-HSCT recipients and developing the appropriate therapeutic regimen may be helpful to reduce the incidence of aGVHD.

Significance of Tacrolimus Blood Concentration Monitoring to the Therapy of Membranous Nephropathy / 中国药房

OBJECTIVE:To investigate the significance of tacrolimus blood concentration monitoring to the therapy of mem-branous nephropathy. METHODS:41 patients with membranous nephropathy received tacrolimus,and the blood concentration of ta-crolimus reached to steady state. The trough concentration of tacrolimus was determined by EMIT. The patients were followed up, and clinical therapeutic efficacies were recorded. The relationship of blood concentration of tacrolimus with clinical efficacy was evaluated by SPSS 16.0 software. RESULTS:The blood concentration of tacrolimus was(7.47±2.74)ng/ml in complete remission (CR)group,(5.72±1.19)ng/ml in partial response(PR)group,and(3.30±1.08)ng/ml in no response(NR)group,with total remission rate of 75.61%. The blood concentration of CR group was the highest,followed by PR group and NR group,there was statistical significance among 3 groups(P<0.05). CONCLUSIONS:The clinical efficacy of tacrolimus in the treatment of nephrot-ic syndrome is correlate to the blood concentration intimately. Trough concentration monitoring of tacrolimus has important signifi-cance to the treatment of membranous nephropathy.

Effect of amlodipine combined with atorvastatin on blood vessels function of hypertension patients with dys-lipidemia / 中国基层医药

Objective To explore the degree of the improvement for hypertension patients with dyslipidemia by amlodipine combination atorvastatin treatment, and analyze the influence on vascular function.Methods 186 hypertension patients with dyslipidemia were selected.According to random number table,they were divided into the control group (91 cases) and the treatment group (95 cases),the control group was given amlodipine treatment,the treatment group was given Atorvastatin Calcium Tablets on the basis of the control group.The main indexes were the difference of systolic and diastolic blood pressure before and after the treatment,and high resolution detection of carot-id artery intima media thickness ( IMT) and carotid plaque area by color Doppler ultrasoundand.Serum total choles-terol ( TC) ,triglyceride ( TG) ,low density lipoprotein cholesterol ( LDL-C) and blood viscosity,hematocrit,erythro-cyte aggregation index were compared the change degree before and after treatment.Results The differences of pre and post-treatment on the systolic and diastolic blood pressure of the treatment group were (25.76 ±4.81)mmHg and (12.40 ±3.66)mmHg,higher than those of the control group,the difference was statistically significant (t=9.48, 8.76,all P<0.05).The differences of pre and post-treatment on IMT and plaque area of the treatment group were (0.10 ±0.11) mm and (0.33 ±0.14) mm2,higher than those of the control group,there was statistical significant differences (t=5.40,5.93,all P<0.05).The differences of pre and post-treatment on TC,TG and LDL-C of the treatment group were(1.06 ±0.38)mmol/L,(0.76 ±0.31)mmol/L and (0.58 ±0.20)mmol/L,higher than those of the control group,the difference was statistically significant (t=6.85,6.13,7.02,all P<0.05).The differences of pre and post-treatment on plasma viscosity,whole blood viscosity,hematocrit and erythrocyte of the treatment group were (0.36 ±0.08)Pa· s,(0.51 ±0.14)Pa· s,(0.41 ±0.12) and (0.31 ±0.12),higher than those of the con-trol group,the difference was statistically significant (t=5.81,4.97,5.11,6.86,all P<0.05).Conclusion The combination of amlodipine and atorvastatin on hypertension patients with dyslipidemia could reduce blood pressure and blood fat significantly,improve blood rheology,which has a good protective effect on vascular function.

The differential expression of vascular endothelial growth factor and its receptor subtypes in myocardial infarction rats / 中国医师杂志

Objective To investigate expressions of the vascular endothelial growth factor (VEGF) family and their receptors in cardiac repair/remodeling after myocardial infarction (MI).Methods The infarcted rat heart model were constructed,real time PCR (RT-PCR) and Western blots (WB) were used.Results Compared to the normal myocardium,VEGF-A was significantly decreased in MI group during the 42 days observation period but decreased at day 1,which was 0.89 ±0.04 of control group in D1,0.25 ±0.03 of control in D14; VEGF-B was significantly suppressed in the infarcted heart,which level was 0.09 ± 0.04 of control; However,VEGF-C and VEGF-D were markedly increased in the infarcted heart in MI group,which was 5.31 ± 0.21 and 9.24 ± 0.47 times of control.Meanwhile,VEGFR-1 and 2 were 0.11 ± 0.02 and 0.14 ± 0.04 of control in the infarcted heart,but VEGFR-3 was significantly increased in blood vessels,6.81 ± 0.42 times of control group.Conclusions VEGF isoforms and VEGFR subtypes were differentially expressed in the infarcted heart.It suggests that these isoforms may regulate multiple responses during cardiac repair/remodeling.
