RESUMO
Objective To investigate the predictive value of new simplified insulin resistance(IR)assessment indexes in identifying subclinical left ventricular systolic function impairment in patients with type 2 diabetes mellitus(T2DM).Methods A total of 150 T2DM patients with preserved left ventricular ejection fraction(LVEF≥50%)who were admitted to Department of Endocrinology of the First Affiliated Hospital of Air Force Medical University from June 2021 to December 2021 were retrospectively analyzed.All patients underwent two-dimensional speckle tracking echocardiography to measure left ventricular global longitudinal strain(GLS).According to GLS value,the subjects were divided into the normal group(GLS≥18%group,n=80)and the impaired group(GLS<18%group,n=70).Some new simplified IR assessment indicators were calculated and compared between the two groups,including body mass index(BMI),TG/HDL-C ratio,triglyceride-glucose(TyG)index,TyG-BMI index,TyG-WHR and metabolic score for IR(METS-IR).Correlation between the GLS and the new simplified IR assessment indexes was analyzed.The receiver operating characteristic(ROC)curve was used to analyze the diagnostic efficacy of different simplified IR assessment indexes,with the area under the curve(AUC)calculated.Furthermore,according to whether the subjects were complicated with hypertension,binary logistics regression analysis was performed to explore the independent correlation between the simplified IR assessment index and GLS<18%.Results Total 150 were included with aged(54.5±13.7)years with 96(64.0%)men and 54(36.0%)women.Compared with the GLS≥18%group,the TG/HDL-C ratio,TyG index,TyG-BMI,and METS-IR of subjects in the GLS<18%group were significantly increased(P<0.05).Pearson correlation analysis showed that TG/HDL-C ratio,TyG index,TyG-BMI,TyG-WHR,and METS-IR were negatively correlated with GLS(P<0.05).ROC analysis showed that TyG index had a certain predictive value for the evaluation of GLS<18%(AUC=0.678,95%CI 0.591-0.765,P<0.001).Stratification based on hypertension and further adjusting for confounding factors,TyG index remains significantly associated with GLS<18%(OR=3.249,95%CI 1.045-10.103,P=0.042).Conclusions The novel simplified insulin resistance evaluation indexes are closely associated with left ventricular subclinical systolic dysfunction in T2DM patients with preserved ejection fraction.TyG index is an effective index to identify left ventricular subclinical dysfunction in these populations.
RESUMO
BACKGROUND:Knee osteoarthritis is a common disease in middle-aged and elderly people.It is a kind of disease that seriously affects the quality of life of patients and even has the risk of disability.Therefore,the pathogenesis and treatment of knee osteoarthritis have become the focus of research.In Chinese medicine,knee osteoarthritis is often treated as"biness,"which is closely related to"biness"caused by blood stasis and blood vessels blocking collaterals in the theory of"blood stasis"in traditional Chinese medicine.Iron overload is a kind of pathological state caused by iron metabolism disorder,which highly coincides with the pathogenic characteristics and clinical manifestations of the"blood stasis"theory of traditional Chinese medicine,and is a risk factor that promotes the development of knee osteoarthritis. OBJECTIVE:Based on the"blood stasis"theory,to summarize the effects of iron overload on cartilage metabolism and subchondral bone reconstruction,to lay a new theoretical foundation for the treatment of knee osteoarthritis with traditional Chinese medicine,and to explore the therapeutic effect of traditional Chinese medicine for promoting blood circulation after interfering with bone tissue. METHODS:CNKI,WanFang database,PubMed and Web of Science databases were searched for relevant literature.The Chinese search terms were"ferroptosis,iron,iron overload,osteoarthritis,blood stasis"and the English search terms were"ferroptosis,iron,iron overload,osteoarthritis,TCM."In the end,76 articles were included for further review. RESULTS AND CONCLUSION:First of all,we explored the potential of the"blood stasis"theory in treating knee osteoarthritis,and found that"blood stasis"is a crucial part in the progress of knee osteoarthritis,indicating that the"blood stasis"theory is the key to the treatment of knee osteoarthritis in traditional Chinese medicine.Secondly,"blood stasis"and iron overload have a high degree of similarity in pathogenic factors,clinical manifestations,and pathogenic characteristics,suggesting the possibility of"blood stasis"theory in treating iron overload.This finding reminds us that iron overload may be an important mechanistic basis for the"blood stasis"theory in the treatment of knee osteoarthritis.The extracts of blood-activating drugs can relieve iron overload and treat knee osteoarthritis,but the specific mechanism is still unclear.Therefore,we believe that the relationship between"blood stasis"theory and iron overload and related mechanisms are important research directions for knee osteoarthritis in the future.The related mechanism of"blood stasis"theory to alleviate iron overload and then treat knee osteoarthritis also provides a theoretical basis for the modernization of traditional Chinese medicine,such as the development of new drugs and innovative usage,and has certain guiding significance for clinical practice.
RESUMO
Objective To observe changes of thickness and elasticity of skeletal muscles in patients with type 2 diabetes mellitus(T2DM)and relative impact factors.Methods Totally 62 T2DM patients(T2DM group)and 60 healthy adults(HC group)were prospectively recruited.Shear wave elastography(SWE)technology was used to measure the maximum Young's modulus(Emax)of the rectus abdominis and gastrocnemius muscles under relaxed and contracted states in both groups.The thickness and elasticity modulus of the skeletal muscles under the two states were compared between groups.Multiple linear regression analysis was performed to screen impact factors of the elasticity modulus of the rectus abdominis and gastrocnemius muscles.Results No significant difference of muscle thicknesses of rectus abdominis,nor of gastrocnemius muscle was found between groups under relaxed and contracted states(all P＞0.05).Under both relaxed and contracted states,the Emax of the rectus abdominis and gastrocnemius muscle in T2DM group were all lower than those in HC group(all P＜0.05).Multiple linear regression analysis showed that in T2DM group,the elasticity modulus of the rectus abdominis and gastrocnemius muscle under both relaxed and contracted states decreased linearly with disease duration,fasting blood glucose(FBG)and glycosylated hemoglobin(HbA1c)(all P＜0.05).Conclusion The elasticity modulus of skeletal muscle decreased in T2DM patients,and the reducing scales linearly related to disease duration,FBG and HbA1c.
RESUMO
Chemotherapy is one of the major approaches for the treatment of metastatic lung cancer, although it is limited by the low tumor delivery efficacy of anticancer drugs. Bacterial therapy is emerging for cancer treatment due to its high immune stimulation effect; however, excessively generated immunogenicity will cause serious inflammatory response syndrome. Here, we prepared cancer cell membrane-coated liposomal paclitaxel-loaded bacterial ghosts (LP@BG@CCM) by layer-by-layer encapsulation for the treatment of metastatic lung cancer. The preparation processes were simple, only involving film formation, electroporation, and pore extrusion. LP@BG@CCM owned much higher 4T1 cancer cell toxicity than LP@BG due to its faster fusion with cancer cells. In the 4T1 breast cancer metastatic lung cancer mouse models, the remarkably higher lung targeting of intravenously injected LP@BG@CCM was observed with the almost normalized lung appearance, the reduced lung weight, the clear lung tissue structure, and the enhanced cancer cell apoptosis compared to its precursors. Moreover, several major immune factors were improved after administration of LP@BG@CCM, including the CD4+/CD8a+ T cells in the spleen and the TNF-α, IFN-γ, and IL-4 in the lung. LP@BG@CCM exhibits the optimal synergistic chemo-immunotherapy, which is a promising medication for the treatment of metastatic lung cancer.
RESUMO
This study aimed to evaluate the efficacy and safety of Biling Weitong Granules in the treatment of stomach ache disorder. Randomized controlled trial(RCT) of Biling Weitong Granules in the treatment of digestive diseases with stomach ache disorder as the primary symptom was retrieved from Chinese and English electronic databases and trial registration platforms from database inception to June 10, 2022. Two investigators conducted literature screening and data extraction according to the screening criteria. The Cochrane risk-of-bias tool(v 2.0) was used to assess the risk of bias in the included studies. Analyses were performed using RevMan 5.4 and R 4.2.2, with summary estimates measured using fixed or random effects models. The primary outcome indicators were the visual analogue scale(VAS) scores and stomach ache disorder symptom scores. The secondary outcome indicators were clinical recovery rate, Helicobacter pylori(Hp) eradication rate, and adverse reaction/events. Twenty-seven RCTs were included with a sample size of 2 902 cases. Meta-analysis showed that compared with conventional western medicine treatments or placebo, Biling Weitong Granules could improve VAS scores(SMD=-1.90, 95%CI[-2.18,-1.61], P<0.000 01), stomach ache disorder symptom scores(SMD=-1.26, 95%CI[-1.71,-0.82], P<0.000 01), the clinical recovery rate(RR=1.85, 95%CI[1.66, 2.08], P<0.000 01), and Hp eradication rate(RR=1.28, 95%CI[1.20, 1.37], P<0.000 01). Safety evaluation revealed that the main adverse events in the Biling Weitong Granules included nausea and vomiting, rash, diarrhea, loss of appetite, and bitter mouth, and no serious adverse events were reported. Egger's test showed no statistical significance, indicating no publication bias. The results showed that Biling Weitong Granules in the treatment of digestive system diseases with stomach ache disorder as the primary symptom could improve the VAS scores and stomach ache disorder symptom scores of patients, relieve stomach ache disorder, and improve the clinical recovery rate and Hp eradication rate, with good safety and no serious adverse reactions. However, the quality of the original studies was low with certain limitations. Future studies should use unified and standardized detection methods and evaluation criteria of outcome indicators, pay attention to the rigor of study design and implementation, and highlight the clinical safety of the medicine to provide more reliable clinical evidence support for clinical application.

This study systematically evaluated the clinical efficacy and safety of Fengliao Changweikang prescription for treating acute gastroenteritis(AGE). The databases of CNKI, Wanfang, VIP, SinoMed, Medline, Cochrane Library and two clinical trial registration platforms were retrieved from inception to August 30, 2022, to collect randomized controlled trial(RCT) on Fengliao Changweikang prescription treating AGE. Two researchers independently conducted literature screening, data extraction, and risk of bias assessment according to pre-established inclusion and exclusion criteria. RevMan 5.4.1 was used for data analysis. Finally, 18 RCTs were included, involving 3 489 patients. Meta-analysis showed that compared with conventional western medicine, Fengliao Changweikang prescription improved the relief rate of abdominal pain(RR=1.27, 95%CI[1.17, 1.38],P<0.000 01); Fengliao Changweikang prescription + conventional western medicine increased the cure rate(RR=1.43, 95%CI[1.12, 1.82], P=0.004), shortened the duration of diarrhoea(RR=-1.65, 95%CI[-2.44,-0.86], P<0.000 1), abdominal pain(RR=-1.46, 95%CI[-2.00,-0.92], P<0.000 01), vomiting(RR=-2.16, 95%CI[-2.51,-1.81], P<0.000 01) and fever(RR=-2.61, 95%CI[-4.00,-1.23], P=0.000 2), down-regulated the level of interleukin-8(IL-8)(RR=-1.07, 95%CI[-1.26,-0.88], P<0.000 01), IL-6(RR=-8.24, 95%CI[-8.99,-7.49], P<0.000 01) and hypersensitive C-reactive protein(hs-CRP)(RR=-3.04, 95%CI[-3.40,-2.69], P<0.000 01) and recurrence of AGE(RR=0.20, 95%CI[0.05, 0.90], P<0.04). In conclusion, Fengliao Changweikang prescription was safe in clinical application. It was beneficial to alleviate the clinical symptoms of diarrhea, abdominal pain, vomiting, and fever, and down-regulate the levels of some serum inflammatory factors in AGE patients. However, considering that few high-quality studies have evaluated the efficacy and safety of Fengliao Changweikang prescription in treatment of AGE, further evidence is needed in the future.

Immune checkpoint inhibitors (ICIs) have been widely used in the treatment of non-small cell lung cancer (NSCLC) . However, ICIs related pneumonia, myocarditis, rash, colitis, nervous system immune-related adverse events (irAEs) , as well as hypothyroidism, ocular irAEs, liver irAEs, etc., can be generated in the process of use, and some irAEs are even fatal. Systemic inflammatory biomarkers as well as chemotherapy, higher body mass index, epidermal growth factor receptor mutation are risk factors for its occurrence. The common irAEs and risk factors are analyzed in order to improve the clinician's understanding of ICIs.
RESUMO
Objective This study aims to explore the formation of the dilemma of"giving care"for disabled elderly people in nursing homes from the perspective of active health.Methods Purposive sampling was used to select caregivers and disabled elderly people from a nursing home in Chongqing as research subjects from July 2022 to December 2022.One-on-one in-depth interviews were conducted and Colaizzi's 7-step thematic analysis method was employed to collect and analyze the interview data.Results 4 themes were identified:①the dominance of the"giving"care concept,including the cultural thoughts of filial piety,passive acceptance of care characteristics and consumer psychology regarding paid services;②insufficient"participation"care ability,including lack of knowledge regarding active health and a weakening of skills to promote participation;③the hindrance to"transformation"of care models,including objective limitations in terms of human resources and delays in adapting aging environments;and ④the decline in"utilization"of internal abilities,including excessive avoidance of potential risks,a heavy workload of care and poor quality of individual care.Conclusion The formation of the dilemma of"giving care"for disabled elderly people in nursing homes is affected by multiple factors such as social background,service system,supply resources,and management mode.Transforming disabled elderly individuals from a state of"passive giving care"to"active participation in their health"is an important measure to realize the concept of positive aging and healthy aging.

RESUMO
Objective:To investigate the effects of intravascular hypothermia combined with early post-pyloric feeding on the neurological function and prognosis in patients with severe ischemic stroke, and to provide a theoretical basis for clinical decision-making on the optimal nutritional support strategy for patients with severe ischemic stroke during intravascular hypothermia treatment.Methods:This was a retrospective, non-randomized, controlled study. A total of 78 patients with first severe ischemic stroke who were admitted to the ICU of Neurology Department, Xuanwu Hospital, Capital Medical University from January 2018 to December 2021 were selected. General information and clinical data of the patients were collected and grouped according to intrvascular hypothermia combined with nutritional support. Patients were divided into early post-pyloric feeding group of 52 cases and early parenteral nutrition group of 26 cases. The neurological prognosis, disease prognosis, nutritional status and complications related to nutritional support of the two groups were retrospectively analyzed.Results:The Glasgow score at 30th day after intravascular hypothermia in the early postpyloric feeding group was (11.25 ± 4.92) points, which was higher than that in the early parenteral nutrition group (8.40 ± 5.53), and the difference was statistically significant ( t=-2.45, P<0.05). After treatment, the serum total protein and hemoglobin of early postpyloric feeding group were (59.56 ± 5.09) g/L and (131.06 ± 19.58) g/L, respectively, which were higher than those of early parenteral nutrition group (56.52 ± 7.94) g/L and (122.07 ± 17.72) g/L. The difference was statistically significant ( t=-2.03, -1.91, P<0.05). The clinical pulmonary infection score of the early postpyloric feeding group was (7.33 ± 0.96) points, which was lower than that of the early parenteral nutrition group (9.42 ± 2.11). The mechanical ventilation time and ICU stay time were (17.46 ± 10.47) days and (28.89 ± 12.59) days, respectively. Compared with the early parenteral nutrition group (25.77 ± 15.20) days and (37.07 ± 17.15) days, the differences were statistically significant ( t=3.28, 2.83, 2.52, all P<0.05). There were no significant differences in catheter-associated bloodstream infection and ICU hospitalization mortality between the two groups (both P>0.05). Conclusions:Intravascular hypothermia combined with early post-pyloric feeding can improve the nutritional status of patients with severe ischemic stroke, effectively control pulmonary infection, shorten mechanical ventilation and hospital stay, and promote neurological repair.
RESUMO
Objective:To identify two pathogenic gene mutations in two families with Alstr?m syndrome (ALMS).Methods:A retrospective clinical study. Two patients and five family members from two Han families of ALMS diagnosed at Henan Eye Hospital from August 2020 to December 2021 were enrolled in this study. All participants underwent comprehensive ophthalmic examinations including best corrected visual acuity (BCVA), color test, slit-lamp, fundus biomicroscopy with slit lamp, fundus color photography, optical coherence tomography (OCT) and full-field electroretinography (ff-ERG) after the detailed history of the patient was taken. Five millilitres peripheral venous blood of each subject was collected, and the whole genome DNA was extracted. The pathogenic genes and mutation sites were identified using whole exome sequencing and the identified mutations were verified by Sanger sequencing. Mutation sites were analyzed via bioinformatics softwares.Results:Family one included one victim and two members and family two included one victim and three members. Proband in the first family was a four-year old boy whose chief complaint was poor vision along with photophobia since born, while proband in the second family was a 12-year old girl whose chief complaint was the same. The boy proband could not distinguish color, and both the anterior segment and fundus were normal. Ellipsoid zone of the boy was unclear in both eyes in OCT, and though rod system function decreased mildly-moderately in both eyes, the cone system function decreased severely in ff-ERG. The girl could not distinguish color as well, and the anterior segment was normal, though obvious pigmentary change could be seen in both retinas. The integrity of outer retinal bands was unclear in both eyes in OCT, and both cone and rod systems function decreased severely in both eyes in ff-ERG. Gene tests and bioinformatics analyze showed c.468dupT and c.10819C>T of ALMS1 gene in family one were novel mutations and c.10819C>T in family one and c.10831_10832del in family two were pathogenic mutations. Conclusions:M1, M2 and M3, M4 may be pathogenic gene variants in family 1 and family 2, respectively. The compound heterozygous mutation, c.468dupT and c.10819C>T of ALMS1 gene was a novel mutation.
RESUMO
Vocal fatigue（VF） is the common clinical symptom of voice diseases. It can also be a separate symptom and is considered to be a signal for the body to rest and to avoid pathological damage to the vocal cords. Therefore, the early identification and evaluation of vocal fatigue is of great value to the early prevention and treatment of vocal diseases. In recent years, there are many researches on the evaluation methods of vocalization fatigue. We searched the relevant literature and summarized the application status of vocal fatigue assessment methods, in order to provide reference for the selection and development of vocal fatigue assessment tools in clinical practice.

RESUMO
Airway remodeling is one of the main pathological features of bronchial asthma.Airway remodeling may lead to increased airway hyperresponsiveness and pulmonary function decline in asthmatic patients.Some studies suggest that airway epithelial cells may play an important role in the development of airway remodeling in asthma, and they can differentiate into mesenchymal cells through epithelial-mesenchymal transition.This article reviews the signaling pathways involved in epithelial-mesenchymal transition, such as TGF-β 1 signaling pathways, Wnt/β-catanin signaling pathway and sonic hedgehog signaling pathway, to further elucidate the molecular mechanisms in airway remodeling in asthma.It provides a new perspective for the study of the pathogenesis of asthma and the development of new, effective and safe targeted therapy.
RESUMO
Objective:To investigate the risk factors for wheezing in the children with HAdV pneumonia.Methods:Ninety-seven cases of children aged 2 to 5 years with HAdV pneumonia were selected from Pediatric Department of Shengjing Hospital of China Medical University from January 2019 to December 2019.Meanwhile, 100 children of the same age without adenovirus pneumonia were recruited as the control group.According to whether wheezing or not, the children with HAdV pneumonia were divided into wheezing group and non-wheezing group.The general characteristics, clinical characteristics and laboratory examination data of HAdV pneumonia group and non-HAdV pneumonia group were statistically analyzed, and the risk factors of wheezing after HAdV pneumonia were analyzed by multivariate logistic regression.Results:Compared with the non-HAdV group, fever duration, serious cases, cases of wheezing in HAdV group were significant different( P<0.05). In laboratory examination, the white blood cell(WBC)count in HAdV group was significantly higher than those in control group( P<0.05). Whereas, hospitalization time, C-reactive protein(CRP), alanine aminotransferase(ALT), creatinine(Cr), creatine kinase(CK), CKMB, and lactic dehydrogenase(LDH)levels in HAdV group were not statistically significant compared with those of the children in non-HAdV pneumonia group( P>0.05). Wheezing occurred in 52.6%(51/97)of children with HAdV pneumonia.Compared with the non-wheezing group, history of wheezing, cases with atopy, serious cases, eosinophils(EO)count, and cases with small airway changes in wheezing group were significantly different( P<0.05). Whereas, atopic family history, hospitalization time, fever duration, lymphocyte(LY)count, WBC count, CRP level, the cases with co-infection and consolidation in lung images in wheezing group were not statistically significant compared with those of the children in non-wheezing group( P>0.05). Multivariate logistic regression analysis showed that the risk of wheezing in children with severe HAdV pneumonia was 2.949 times as much as those without severe HAdV pneumonia.The risk of wheezing in children with HAdV pneumonia with atopic constitution was 3.930 times as much as those without atopiy. Conclusion:The incidence of wheezing in children with HAdV pneumonia is higher than those in children of non-HAdV pneumonia.Severe cases and atopy are the independent risk factors for wheezing in the children with HAdV pneumonia.
RESUMO
Objective:Summarizing the clinical characteristics of extraneural metastasis in childhood medulloblastoma.Methods:A total of 616 cases with medulloblastoma treated in Beijing Shijitan Hospital from April 2010 to April 2019 were analyzed retrospectively, among which 11 cases developed extraneural metastasis.The age of onset, location and time of extraneural metastasis, pathological and molecular typing, treatment and prognosis were descriptively analyzed.The differences of blood biochemical indexes between medulloblastoma cases with and without extraneural metastasis were statistically analyzed by t test. Results:As of February 2020, the median follow-up period was 16 months (ranging from 3 to 69 months). Eleven cases, including 8 males and 3 females, were diagnosed with extraneural metastasis, with the incidence being about 1.8%.The median age of medulloblastoma was 6 years (2-10 years), and the median age at presentation of extraneural metastasis was 7 years (2-12 years). Extraneural metastasis occurred from 0.5 months to 38.0 months after the operation, and the affected location includes bone (6 cases), bone marrow (3 cases), lung (3 cases), pelvis (2 cases) and abdominal cavity (1 case). In these patients, the range of lactic dehydrogenase (LDH) was (2 298.00±1 570.70) U/L and neuron-specific enolase (NSE) was (201.00±68.34) μg/L, which were significantly higher than those in patients without extraneural metastasis [(249.50±46.28) U/L and (22.80±7.12) μg/L, all P<0.05]. Partial patients were treated with chemotherapy, while the majority of them were treated with palliative treatment in the terminal stage, with the survival period mostly less than 10 months. Conclusions:Although there is a low incidence of extraneural metastasis in medulloblastoma pediatric patients, the prognosis of these patients with extraneural metastasis is poor and most of them would die within one year.The most common sites include bone, followed by bone marrow and lungs, which may be related to the spread of cerebrospinal fluid and the increased levels of LDH and NSE.
RESUMO
Objective:To explore the effect of neutrophil-lymphocyte ratio (NLR) at the initial visit on the survival of children with newly diagnosed medulloblastoma (MB).Methods:This was a case-control study involving 61 children with newly diagnosed MB at the Department of Pediatrics, Beijing Shijitan Hospital, Capital Medical University from August 2018 to January 2020 .The blood cell counts, lymphocyte subsets and immunoglobulin in the periphe-ral blood were measured to calculate NLR at the initial visit.Based on the cut-off value determined by receiver opera-ting characteristic (ROC) curve, patients were divided into high NLR group (≥ 2.07, n=21) and low NLR group (<2.07, n=40). The progression-free survival (PFS) and overall survival (OS) between 2 groups were analyzed by the Kaplan-Meier method, followed by Log- rank test.The correlation between NLR at the initial visit with clinical characteristics, lymphocyte subsets and immunoglobulin of children with newly diagnosed MB was analyzed.Differences between groups were compared by the Chi- square test, Mann- Whitney U test and independent sample t test. Results:The survival analysis showed that the relapse rate (38.1% vs.10.0%, χ2=6.879, P=0.016) and mortality rate (19.0% vs.0, χ2=8.154, P=0.011) were significantly higher in high NLR group than those of low NLR group.PFS (12 months vs.19 months, χ2=9.775, P=0.002) and OS (19 months vs.20 months, χ2=8.432, P=0.004) were significantly shorter in high NLR group than those of low NLR group.No significant differences in clinical characteristics were detected between groups (all P>0.05). Compared with low NLR group, the percentage of T lymphocyte[(67.93±6.37)% vs.(73.38±8.08)%, t=2.886, df=48.865, P=0.006], T helper cells (Th)[(30.86±5.53)% vs.(34.29±7.44)%, t=2.037, df=51.981, P=0.047], and T suppressor cells (Ts)[(27.39±5.50)% vs.(30.84±6.58)%, t=2.164, df=47.581, P=0.035] were significantly lower in high NLR group.Spearman correlation analysis showed a negative correlation between NLR and T lymphocyte count ( r=-0.303, P=0.018), and Ts lymphocyte count ( r=-0.260, P=0.043). Conclusions:Children with newly diagnosed MB expressing a high level of NLR had a poor prognosis, which may be associated with T lymphocyte and Ts lymphocyte.
RESUMO
Both subclinical hypothyroidism(SCH)and cognitive dysfunction are common comorbidities in the elderly.SCH is often accompanied by elevated levels of uric acid and blood lipids.It remains controversial whether SCH and cognitive dysfunction are related, and whether elevated blood uric acid and blood lipids become risk factors for cognitive impairment.This paper aims at analyzing these risk factors to explore the association of SCH with cognitive impairment, and to explore the role of high uric acid and high blood lipid levels on cognitive impairment.
RESUMO
The incidence rate of chronic airway inflammatory diseases caused by airway mucus hypersecretion caused by mycoplasma pneumoniae(MP) infection is increasing year by year.In this paper, the damage of MP on airway mucosa through its adhesion, migration, community acquired respiratory distress syndrome toxin(CARDS Tx)and other virulence factors is described, which directly damages the structure and function of airway epithelium and affects the metabolism of ciated cells.It can also cause the increase of airway pro-inflammatory cytokines and the up regulation of toll-like receptor, resulting in the increase of airway mucus secretion.In addition, when MP infects airway epithelial cells, it will increase mucin(MUC)production through signal transduction pathway, which will increase the secretion of MUC5AC and lead to airway mucus hypersecretion.Controling airway mucus hypersecretion caused by MP infection can reduce the occurrence of chronic airway inflammation and helpful to the treatment of refractory MP infection.
