Objective To observe the therapeutic effect of the combination of traditional Chinese medicine and western medicine for pediatric mycoplasma pneumonia (accumulation of phlegm-heat syndrome).Methods Consecutive 116 children treated for mycoplasma pneumonia ( accumulation of phlegm-heat syndrome ) were randomly divided into the two groups by software:the treatment group(58 cases) and control group(58 cases).The control group accepted the sequential therapy of azithromycin ,and the treatment group accepted azithromycin sequential therapy ,in combina-tion with traditional Chinese decoction Wuhu Tingli Dazao Xiefei Tangand Chinese medicine iontophoresis thera-py.Clinical indicators were observed:antifebrile time,lung sound disappearing time,cough disappearing time,lung inflammation (X-ray) disappearing time.Results Antifebrile time[(2.4 ±0.5)d vs (4.2 ±0.6)d,t=3.221,P<0.05],lung sound disappearing time [(5.2 ±0.7)d vs (7.6 ±1.1)d,t=3.514,P<0.05],cough disappearing time [(9.4 ±1.6) d vs (11.7 ±2.1) d,t =3.661,P<0.05)] and lung inflammation ( X-ray) disappearing time [(13.2 ±2.3)d vs (15.5 ±2.5)d,t=3.101,P<0.05)] in the treatment group were shorter than those of the con-trol group;Hospital stays [(6.3 ±1.5)d vs (8.6 ±2.8)d,t=3.712,P<0.01] and hospitalization costs [(3 976.4 ± 473.5)yuan vs (5 468.1 ±726.6)yuan,t=3.804,P<0.01)] in the treatment group were significantly less than those of the control group .Conclusion The therapeutic effects of the combination of traditional Chinese medicine and western medicine for pediatric mycoplasma pneumonia ( accumulation of phlegm -heat syndrome ) is better than single western medicine treatment ,which can shorten hospital stays and reduce treatment costs ,deserves clinical promotion .

Objective To obtain better insights into transmission dynamics of macrolide resistance genes between human and animal Enterococcus strains.Methods The antimicrobial susceptibility to 8 anti-bioties of 52 Enterococci isolated from animal and 55 Enterococci isolated from human was determined.PCR was used to detect the macrolide resistance genes ermB and mefA,tetracycline resistance genes tetM,and the integrase gene int of Tnl545 of the total 107 strains.Forty-nine ermB positive strains were chosen to be se-quenced.Filter mating experiments were taken.Results The resistance rate to erythromycin were 89.09% and 80.77%for isolates from human and animal:and resistance rate to tetracycline were 80.00%and 67.3l%for isolates from human and animal.respectively.All isolated Enterococci strains were found sensi-tive to vancomycin ermB was detected in 61.82% human Enterococci and 53.85% porcine ones.Identical er-mB gene sequences were found in animal and human Enterococci.Transfer of the ermB gene from porcine E.faecalis to human E.feacalis was successful.and the transfer frequency is 1.2×10-5.Conclusion En-terococci have a high resistance rate to erythromycin and some other antibio tics,especially in pediatric iso-lates:but still very sensitive to glycopeptide.ermB was the predominant genes for macrolide and tetracy-cline.Identical ermB gene sequences were present in animal and human Enterococci and that transfer of the ermB gene from porcine E.faecalis to human E.faecalis and vice versa is possible.but probably occurs at a low frequency.

Objective To determine the drug-resistance rate of Enterococci isolated from patients of 5 padiatric hospitals located at different areas in China,and to investigate the distribution of resistance genes ermB,mefA,tetM and the integrase gene intTn of Tn1545 in Enterococci.Methods The antimicrobial susceptibility to 8 antibiotics of 2 216 Enteroeocei isolates was determined.PCR was used to detect the macrolide resistance genes ermB and mefA,tetracycline resistance genes tetM,and the integrase gene int-Tn of Tn1545.Results The resistance rates to erythromycin,ampicillin,gentamicin and teicoplanin were 86.5%,48.0%,60.5% and 0.7%,respectively.All isolated Enterococci straim were found sensitive to vancomycin.Of the detected 225 strains,70.7% of the 225 detected strains carried ermB gene while 75.1% of them carried tetracycline resistance gene tetM:only one strain had mefA.The presence of ermB gene in erythromycin MIC＞256 mg/L straim group(95.7%)strains was higher than those in erythromycin MIC＜256 mg/L group(2.5%).The int-Tn gene was detected in 40.9%(92/225)of the 225 test strains.The presence of ermB gene in int-Tn positive group strains was higher(84.8%)than those in int-Tn negative strains group(60.9%).So did the tetM in int-Tn positive group(83.7%)compared with those in int-Tn negative group(70.0%).Conclusions Enterococci sbowed a high resistance rate to the antibiotics we monitored,especially to erythromycin;but still very senstive to glycopeptide antibiotics. Resistance to macrolide in Enterococci collected from clinical in five Children's Hospital was generally mediated by methylation of 23S rRNA via ermB methylase. Enterococci resistance to tetracycline was predominantly due to ribosomal protection encoded by tetM. There was a strong relationship of the ermB and tetM genes with Tn1545-related elements.

OBJECTIVE: To explore the effects and mechanisms of the long-snake moxibustion on ankylosing spondylitis (AS) based on Th17/Treg/Th1 immune imbalance. METHODS: A total of 60 AS patients were randomized into an observation group and a control group, 30 cases in each one. In the observation group, the long-snake moxibustion therapy was used on the acupoints of the governor vessel from Dazhui (GV 14) to Yaoshu (GV 2) as well as the bilateral Jiaji (EX-B 2) alternatively. The moxibustion was given once a day, for 7 days continuously as one course. There were 3 days at the interval between the courses and 4 courses were required. In the control group, the routine western medication was provided, the salazosulfapyridine combined with non-steroidal anti-inflammatory drugs were used, for 7 days continuous as one course. A total of 4 courses of medication were required. The enzyme linked immunosorbent assay (ELISA) was adopted to determine the levels of interleukin-6 (IL-6), interleukin-17 (IL-17), interleukin-23 (IL-23) and tumor necrosis factor-α (TNF-α). The real-time quantification polymerase chain reaction (RT-PCR) was used to determine the mRNA expressions of the specific transcription factors, FoxP3 and T-bet of the helper 17 cells (Th17), regulatory T cells (Treg) and T helper 1 cells (Th1). The flow cytometry was applied to determine the rates of Treg, Th1 and Th17, as well as the changes of the inflammatory reaction index, C-reactive protein (CRP), and erythrocyte sedimentation rate (ESR). The therapeutic effects were compared between the two groups. RESULTS: After treatment, the total effective rate was 93.3% (28/30) in the observation group, which was better than 86.7% (26/30) in the control group (<0.05). After treatment, the levels of CRP, ESR, IL-6, IL-17, IL-23 and TNF-α, as well as the rate of Th17 were reduced significantly as compared with those before treatment in the observation group (all <0.05). The mRNA expressions of FoxP3 and T-bet and the rates of Treg and Th1 were increased as compared with those before treatment (all <0.05). The change degree in the observation group was significant as compared with the control group (all <0.05). In the control group, the levels of CRP, ESR, IL-6, IL-17, IL-23 and TNF-α, as well as the rate of Th17 were reduced, and the mRNA expressions of FoxP3 and T-bet and the rates of Treg and Th1 were increased after treatment. But the changes were not significant as compared with those before treatment (all >0.05). CONCLUSION The long-snake moxibustion effectively relieves the clinical symptoms in AS patients and regulates the Th17/Treg/Th1 immune imbalance. Its effect target is probably related to the modulation of the AS immune derangement and the inflammatory responses induced by immune derangement so as to achieve the dual-positive regulatory effect.

Cognitive impairment is the most common non-motor symptom with the highest disability rate in patients with Parkinson disease(PD).PD patients often experience cognitive impairment and frailty with the increase in age and the progression of the disease,which can seriously affect their quality of life.However,the research on the association be-tween PD cognitive impairment(PD-CI)and frailty is still in the exploratory stage.This study reviews the association be-tween PD-CI and frailty,in order to enhance the understanding of clinical healthcare workers,provide early intervention opportunities for PD-CI patients,delay their progression to PD dementia,and improve their quality of life.

Objective:To explore the effect of feedback health education combined with positive psychological suggestion on the rehabilitation of patients undergoing artificial total knee arthroplasty.Methods:From August 2020 to July 2021, the convenient sampling method was used to select 126 patients with artificial total knee arthroplasty admitted to the Orthopedic Department of Henan Provincial People's Hospital. They were randomly divided into the control group and the observation group in a 1∶1 ratio using a random number table method. The control group received routine health education combined with positive psychological suggestion, while the observation group received feedback based health education combined with positive psychological suggestion intervention. The level of knowledge, attitude and practice, scores on the Self-Rating Anxiety Scale (SAS), Self-Rating Depression Scale (SDS), Visual Analogue Scale (VAS), American Knee Society (AKS) score, knee swelling rate and nursing satisfaction were compared between two groups of patients.Results:The knowledge, attitude and practice scores of the two groups at discharge were higher than those at admission ( P<0.05), and the knowledge, attitude and practice scores of the observation group were higher than those of the control group at discharge ( P<0.05). The SAS and SDS scores of the observation group were lower than those of the control group before and on the third day after surgery ( P<0.05). The VAS of the observation group on the first day and 2 weeks after surgery were lower than those of the control group ( P<0.05), while AKS was higher than that of the control group ( P<0.05). The postoperative swelling rates in the observation group were lower than those in the control group at 1 week and 3 months after surgery ( P<0.05). The nursing satisfaction scores of the observation group in terms of health education, service attitude, department environment, psychological intervention, and nursing outcomes were higher than those of the control group ( P<0.05) . Conclusions:Feedback health education combined with positive psychological cues can improve the knowledge, attitude and practice levels of patients undergoing artificial total knee arthroplasty, reduce anxiety and depression, and improve rehabilitation effectiveness and nursing satisfaction.

Group A Streptococcus (GAS) is a very important pathogen, especially for children.On a global scale, GAS is an important cause of morbidity and mortality.But the burden of disease caused by GAS is still unknown in China and also has not obtained enough attention.For this purpose, the expert consensus is comprehensively described in diagnosis, treatment and prevention of GAS diseases in children, covering related aspects of pneumology, infectiology, immunology, microbiology, cardiology, nephrology, critical care medicine and preventive medicine.Accordingly, the consensus document was intended to improve management strategies of GAS disease in Chinese children.

BACKGROUND:In consideration of the food safety and ecological safety of transgenic plants,the retention of marker genes is the primary safety issue affecting transgenic plants. OBJECTIVE:Based on the principle of immune caries prevention,our research team successfully constructed the plant anti-caries vaccine fusion gene expression vector pCAMBIA-E8-APB-DOCK8 for these two caries causing virulence factors surface protein and glucosyltransferase,which provides a basis for the research and development of transgenic plant vaccine. METHODS:In this study,the selective marker genes Km and GUS in the plant caries vaccine fusion gene expression vector pCAMBIA-E8-APB-DOCK8 were removed by DNA recombination technology through a series of steps such as DNA fragment separation,connection,transformation,clone detection,and sequencing. RESULTS AND CONCLUSION:The efficiency of marker gene removal was 99%.This study has laid a good experimental foundation for the safe production of transgenic plant vaccine against dental caries,and also provided ideas for the construction of other plant vaccine vectors.
