Abstract: Objective　To explore the correlation between levels of hypersensitive C-reactive protein (hs-CRP) and procalcitonin (PCT) in serum and alveolar fluid and severity of disease in children with lobar pneumonia. Methods　A total of 112 children diagnosed with lobar pneumonia from September 2020 to September 2021 were selected as the research subjects. The levels of hs-CRP and PCT in serum and alveolar fluid were detected by double antibody sandwich enzyme-linked immunosorbent assay (ELISA). The children were divided into severe group (clinical pulmonary infection score, CPIS≥6 points) and mild group (CPIS<6 points) according to the severity of disease, and further classified into good prognosis group (cured, improved) and poor prognosis group (uncured) according to their treatment outcomes. The correlation of levels of hs-CRP and PCT in serum and alveolar fluid with disease severity in children and their predictive value on prognosis were analyzed. Results　The levels of serum hs-CRP and PCT in severe group were (17.73±3.26) μg/L and (8.59±1.84) μg/L, which were significantly higher than corresponding (12.58±3.09) μg/L, and (5.62±1.59) μg/L in mild group (P<0.05); the levels of hs-CRP and PCT in alveolar fluid in severe group were (21.25±4.18) μg/L and (8.71±1.54) μg/L, which were significantly higher than corresponding (13.79±2.76) μg/L and (5.38±1.69) μg/L in mild group (P<0.05). The levels of hs-CRP and PCT in serum and alveolar fluid were positively correlated with CPIS scores (r=0.398, 0.441; 0.475, 0.586, P<0.05). The levels of hs-CRP and PCT in serum in poor prognosis group were (20.09±4.20) μg/L and (13.35±2.91) μg/L, which were significantly higher corresponding (8.75±2.19) μg/L and (6.28±1.31) μg/L in good prognosis group (P<0.05). The levels of hs-CRP and PCT in alveolar fluid were (23.70±4.29) μg/L and (10.73±2.04) μg/L, which were higher than corresponding (15.08±3.56) μg/L and (5.79±1.10) μg/L in poor prognosis group (P<0.05). There was no significant difference in AUC between combined detection of serum indicators and combined detection of alveolar perfusion fluid indicators in predicting the prognosis of children with lobar pneumonia (P>0.05). Conclusions　The levels of hs-CRP and PCT in serum and alveolar fluid of children with lobar pneumonia are significantly increased and positively correlated with the severity of disease. However, the predictive value of the combined detection of serum indicators and combined detection of alveolar perfusion fluid indicators for the prognosis of children with lobar pneumonia is comparable.

Objective To investigate the effects of pollution on nonspecific immune function of the children living nearby a municipal solid waste landfill.Methods The concentration of lysozyme and SIgA of saliva came from 951 children who were selected from 3 schools nearby the landfill were analyzed by cluster sampling while the outside air pollutants were detected in 2006.The high-exposure group included 360 students living in a radius of less than 2 km from the landfill,the low exposure group was consist of 361 students living in a radius of 2-5 km,the others 230 students living in more than 5 km were taken as the control group.Results The results showed that the pollutants levels were concerned with the location of the landfill,the nearer to the landfill,the higher concentration of CH4,NO2,SO2,NH3,H2S and PM10 except CO.The level of saliva lysozyme ranked as high exposure group,low exposure group and the control group were 61.40,71.37 and 76.10 ?g/ml and the same rank for SIgA were 204.11,224.28,248.44 ?g/ml,with significant differences (P

Background and purpose:HIF-1?、HER-2 and survivin are all considered as important prognostic factors of breast cancer,but the relationships among them are poorly understood.We investigated the expression of HIF-1?、HER-2 and survivin in Breast Carcinoma,and explored the relationship among the three prognostic factors.Methods:The expressions of HIF-1?、HER-2 and survivin were detected by immunohistochemistry in 51 human Breast Carcinoma samples.Results:① 28(54.88%),11(21.69%) and 35(68.62%) were positive for HIF-1?、HER-2 and survivin,respectively.② A significant difference was found in terms of the overexpression of HER-2 between the samples with HIF-1? either positive or negatiwe(P0.05).Conclusions:The positive expression of HIF-1? was strongly correlated with the overexpression of HER-2,but not survivin in breast carcinoma.

The phenomenon of recessive absence was initiated by many malpractices in current medical educational system.In this article we try to analyze this phenomenon,speculate the subjective and objective reasons,propose countermeasures such as improving teachers quality,reforming traditional teaching mode,strengthening medical ethics education,enriching teaching means and addressing student-centered lectures.

Oncology is extensive in contents,covering a wide range of organs,systems and clinical specialties.Here,we discuss the feasibility and necessity of flipping the classroom teaching through the introduction of Oncology and through the implementation of flip classroom teaching for oncology graduate students,this paper analyzes the evaluation of the classroom teaching by the teachers and students,and compares the assessment results of students under different teaching methods.The results show that the flipped class can promote students' initiative learning,promote students' classroom participation,and help students to internalize and consolidate their knowledge of oncology in the theoretical teaching of graduate oncology.

In order to further improve the curative effect of the herb-participated moxibustion on umbilicus, we collected a wide range of literature on herb-participated moxibustion on umbilicus and then systematically arranged them to analyze and summarize the technology and operating methods of herb-participated moxibustion on umbilicus. We also briefly discussed issues on application of medicine, locust tree skin and ginger, the method of kneading dough for medical uses, and the appropriate size of moxa cone and its using frequency in order to form clear concepts and standardized operations to provide theories and operational basis for the clinical application of modern herb-participated moxibustion on umbilicus.

Methyl valerate (MVA) pathway is one of the important ways for synthesis of terpenoids. This study was based on data of the transcriptome sequencing of Magnolia officinalis, the associated genes MoACOT, MoHMGS, MoHMGR, MoMK in methyl valerate (MVA) pathway, were completed in detail by using bioinformatics methods. The results of analysis showed that MoACOT and MoMK were stable hydrophobic proteins, MoHMGS and MoHMGR were unstable hydrophobic protein. The secondary structures of all proteins were hybrid architecture,and alpha helical were the major motifs. There were no clear transmembrane domains in MoACOT, MoHMGS and MoMK, but two transmembrane domains were founded in MoHMGR which were from 39-61 aa and 82-104 aa resepectively. The results of evolutionary relationship analysis showed that MoACOT, MoHMGS, MoHMGR and MoMK had relative close relationship to angiosperm or dicotyledonous plants, and accorded with genetic evolution rule. From transcriptome data, transcripted level of MoACOT, MoHMGS, MoHMGR, MoMK in M. officinalis and M. officinalis var. biloba was not significantly different. The result provided theoretical reference for study on Methyl valerate (MVA) pathway of terpenoid of M. officinalis.

To obtain the key genes for chlorogenic acid biosynthesis of Lonicera hypoglauca, four new genes ware obtained from the our dataset of L. hypoglauca. And we also predicted the structure and function of LHPAL4, LHHCT1 , LHHCT2 and LHHCT3 proteins. The phylogenetic tree showed that LHPAL4 was closely related with LHPAL1, LHHCT1 was closely related with LHHCT3, LHHCT2 clustered into a single group. By Real-time PCR to detect the gene expressed level in different organs of L. hypoglauca, we found that the transcripted level of LHPAL4, LHHCT1 and LHHCT3 was the highest in defeat flowers, and the transcripted level of LHHCT2 was the highest in leaves. These result provided a basis to further analysis the mechanism of active ingredients in different organs, as well as the element for in vitro biosynthesis of active ingredients.
