[ Objective ] The research aimed to discuss the occurrence regularity of apple early defoliation disease and control effects of fungicides in west Sichuan plateau. [ Method ] Apple early defoliation disease in west Sichuan plateau was systematically investigated during 2009 and 2011, and the control effects of different fungicides during different spraying periods were studied. [ Result] The species of pathogen mainly was Marssonina ma/i （ P. Henn）, accounting for 32.5%, Phyl-losticta Pirina Sa accounted for 29.9%, and Alternaria mali Roberts accounted for 25.7%. The field fluctuation regularity was as follows ： the disease generally be- gan in the mid-May and ended in early and middle October with only one damage peak during the whole year, the fluctuation had positive correlation with rainfall （ R2 =0.891 8 ＊ ＊ ）. Control test showed that 40% flusilazole had the best control effect （86.5%）, which was best to apply after anthesis. [ Conclusion ] The paper provided theoretical basis for the effective control against apple early defoliation disease.

Classification of Short Time Series in Early Parkinson’s Disease With Deep Learning of Fuzzy Recurrence Plots

There are many techniques using sensors and wearable devices for detecting and monitoring patients with Parkinson’s disease(PD).A recent development is the utilization of human interaction with computer keyboards for analyzing and identifying motor signs in the early stages of the disease.Current designs for classification of time series of computer-key hold durations recorded from healthy control and PD subjects require the time series of length to be considerably long.With an attempt to avoid discomfort to participants in performing long physical tasks for data recording,this paper introduces the use of fuzzy recurrence plots of very short time series as input data for the machine training and classification with long short-term memory(LSTM)neural networks.Being an original approach that is able to both significantly increase the feature dimensions and provides the property of deterministic dynamical systems of very short time series for information processing carried out by an LSTM layer architecture,fuzzy recurrence plots provide promising results and outperform the direct input of the time series for the classification of healthy control and early PD subjects.

Bioinformatics Analysis Raises Candidate Genes in Blood for Early Screening of Parkinson's Disease

Parkinson＇s disease （PD） is a typical degenerative disease, which is characterized by the most obvious symptoms of movement dysfunction, including shaking, rigidity, slowness of movement and difficulty in walking and gait. This disease can not be clearly identified through laboratory tests at present, thus application of high-throughput technique in studying the expression profiles of PD helps to find the genetic markers for its early diagnosis. Studies on expression profiles of neurodegenerative diseases have revealed the novel genes and pathways involved in the progress of illness. In this study, the expression profiles of PD in blood were compared, showing that 181 differentially expressed genes （DEG） exhibit a similar expression trend both in patients and in normal controls.

The enlightenment and application of“Laxative method used in early stage of Febrile Disease”in treating COVID-19

The theory of the TCM laxative method is rich in content.Doctors of past dynasties have used it to treat febrile diseases.And the theory of“Laxative method used in early stage of Febrile Disease”has been praised by later generations.It advocates chasing away evil influence early and paying attention to the laxative method to prevent the spread of disease.the Novel Coronavirus(COVID-19)Infectious Pneumonia belongs to the category of"epidemic"in traditional Chinese medicine.The reasonable application of the cathartic is an important way to provide a way out for evil.However,don’t be blind to use laxative method,you should get it at the right time.The treatment of COVID-19 has different solution at different stages.You should adapt to the changes of the disease to use cathartic.A case in here is attached for reference.

Lipocalin-2 as a biomarker for diabetic nephropathy

Diabetes is a major global public health issue.The prevalence of type 1 diabetes is comparatively static,as hereditary and genetic causes are involved,while type 2 diabetes(T2D)prevalence is increasing day by day.T2D is associated with chronic complications,including diabetic neuropathy(DN),nephropathy,retinopathy,and other complications like diabetic foot.DN is the main complication of both types of diabetes.DN can be diagnosed by routine laboratory tests,microalbuminuria>300 mg/24 h,and a gradual decrease in glomerular filtration rate.As the appearance of microalbuminuria is a late manifestation,an early marker for renal damage is needed.Lipocalin-2,also known as neutrophil gelatinaseassociated lipocalin(NGAL),is a small protein purified from neutrophil granules and a good marker for kidney disease.NGAL is a transporter protein responsible for many physiological processes,such as inflammation,generation of the immune response,and metabolic homeostasis.NGAL has been reported to depict the early changes in renal damage when urine microalbumin is still undetecable.Therefore,elucidating the role of NGAL in detecting DN and understanding its mechanism can help establish it as a potential early marker for DN.

Detection of HIV-1 antigen based on magnetic tunnel junction sensors

We report a p24(HIV disease biomarker)detection assay using an MgO-based magnetic tunnel junction(MTJ)sensor and 20-nm magnetic nanoparticles.The MTJ array sensor with sensing area of 890×890μ2 possessing a sensitivity of 1.39%/Oe was used to detect p24 antigens.It is demonstrated that the p24 antigens could be detected at a concentration of 0.01μg/ml.The development of bio-detection systems based on magnetic tunnel junction sensors with high-sensitivity will greatly benefit the early diagnosis of HIV.

Apolipoprotein E polymorphism in the early onset of coronary heart disease

Objective To assess the relationship between apolipoprotein E (apoE) polymorphism and the early onset of coronary heart disease (CHD) and the effect of apoE on lipids and lipoproteins in healthy Chinese subjects. Methods Sixty-eight patients with CHD younger than 55 years (CHD1), 136 patients with CHD older than 65 years (CHD2), and 136 healthy subjects were enrolled, and their plasma levels of triglyceride (TG), total cholesterol (TC) and high density lipoprotein cholesterol (HDL-C) were determined. The apoE genotypes were identified by polymerase chain reaction-restriction fragment length polymorphism. Results apoE 3/4 genotype and E4 allele frequency in the CHD1 group were higher than those in the CHD2 group and healthy subjects, while no differences were found between CHD2 and healthy subjects. Meanwhile, the plasma levels of TC and low density lipoprotein cholesterol (LDL-C) were higher in the CHD2 group than in both CHD1 group and healthy subjects.Each apoE isoprotein has variable TC and LDL-C levels that is E2 (E2/2+E2/3)＜E3(E3/3)<E4(E4/4+E3/4). Conclusion apoE is one of the genetic factors that affect TC and LDL-C levels, and apoE 4 has a very close relation to CHD, suggesting that apoE 4 is an independent genetic factor of the early onset of CHD.

Immunotherapy in triple-negative breast cancer:A literature review and new advances

Triple-negative breast cancer(TNBC)is a highly complex,heterogeneous disease and historically has limited treatment options.It has a high probability of disease recurrence and rapid disease progression despite adequate systemic treatment.Immunotherapy has emerged as an important alternative in the management of this malignancy,showing an impact on progression-free survival and overall survival in selected populations.In this review we focused on immunotherapy and its current relevance in the management of TNBC,including various scenarios(metastatic and early-neoadjuvant,adjuvant-),new advances in this subtype and the research of potential predictive biomarkers of response to treatment.

Increased Serum Cystatin C in Early Parkinson’s Disease with Objective Sleep Disturbances

Background：Sleep disturbance is one of the major non-motor symptoms which cause the disability of Parkinson’s disease （PD） patients. Cystatin C （CysC） is a more sensitive biomarker than serum creatinine or estimated glomerular filtration rate. Previous studies have reported altered CysC levels in neurodegenerative disorders and sleep disorders. This study aimed to explore the correlations of serum CysC levels and objective sleep disturbances in early PD.Methods：We recruited 106 early PD patients and 146 age- and sex-matched controls. All participants underwent clinical investigation and video-polysomnography. Sleep parameters and serum levels of CysC were measured. Then, we investigated the relationships between CysC and clinical variables and objective sleep disturbances in early PD patients.Results：The mean serum level of CysC was significantly higher in patients with early PD （1.03 ± 0.19 mg/L） compared to controls （0.96 ± 0.15 mg/L, P = 0.009）. There were significantly positive correlations between serum CysC levels and age （r = 0.334, P 〈 0.001）, gender （r = 0.264, P = 0.013）, and creatinine levels （r = 0.302, P = 0.018） in early PD patients. Increased serum CysC levels in early PD patients were significantly associated with higher apnea and hypopnea index （AHI） （r = 0.231, P = 0.017）, especially hypopnea index （r = 0.333, P 〈 0.001）. In early PD patients, elevated serum CysC levels were positively correlated with oxygen desaturation index （r = 0.223, P = 0.021）, percentage of time spent at oxygen saturation （SaO2） 〈90% （r = 0.644, P 〈 0.001）, arousal with respiratory event during sleep （r = 0.247, P = 0.013）. On the contrary, the elevated serum CysC levels were negatively correlated with mean and minimal SaO2 （r = ？0.323, ？0.315, both P = 0.001） in PD patients.Conclusions：The level of serum CysC was higher in early PD patients. PD patients with elevated serum CysC levels had more respiratory events and more severe oxygen desaturation. Therefore, the serum CysC levels may predict the severities of sleep-disordered breathing problems in early PD patients.

Genetics on early onset inflammatory bowel disease:An update

Inflammatory bowel disease(IBD)is more common in adults than in children.Onset of IBD before 17 years of age is referred as pediatric onset IBD and is further categorized as very early onset IBD(VEO-IBD)for children who are diagnosed before 6 years of age,infantile IBD who had the disease before 2 years of age and neonatal onset IBD for children less than 28 days of life.Children presenting with early onset disease may have a monogenic basis.Knowledge and awareness of the clinical manifestations facilitates early evaluation and diagnosis.Next generation sequencing is helpful in making the genetic diagnosis.Treatment of childhood IBD is difficult;targeted therapies and hematopoietic stem cell transplantation form the mainstay.In this review we aim to summarize the genetic defects associated with IBD phenotype.We describe genetic location and functions of various genetic defect associated with VEO-IBD with their key clinical manifestations.We also provide clinical clues to suspect these conditions and approaches to the diagnosis of these disorders and suitable treatment options.

Hyperlipidemia in early adulthood increases long-term risk of coronary heart disease

Background Many young adults with moderate hyperlipidemia do not meet statin treatment criteria under the new American Heart Association/American College of Cardiology cholesterol guidelines because they focus on 10-year cardiovascular risk. We evaluated the association between years of exposure to hypercholesterolemia in early adulthood and future coronary heart disease （CHD） risk.

Effect of nursing-based on early rehabilitation on quality of life in elderly patients with cardiovascular disease:A randomized controlled trial

Background Patients with cardiovascular disease（CVD） have a reduced quality of life（QOL） partly due to their limited range of physical activity and independence. The objective of this study was to investigate whether the nurse based early cardiac rehabilitation will be improved QOL in elderly patients with CVD after8-week treatment from baseline and post intervention, compared with conventional care. Methods Sixty-six elderly patients with CVD were randomly assigned（using the coin tossing method） to either the ‘early cardiac rehabilitation＇ group（i.e. the experimental group）, and the control group（i.e. routine care group） for 8weeks between June 2013 and June 2014, with 33 participants in each group. The control group received routine CVD care, and the experiment group received early rehabilitation care in addition to routine CVD care.The outcome measures included the Short Form-36 Health Survey（SF-36）, and Self-rating Anxiety Scale（SAS）. Results There were non-significant differences between the groups at baseline in age, sex, duration of the disease, length of hospitalization, total number of comorbid conditions, and total number of medications（P 〉 0.05）. Following 8-week treatment, all groups improved their QOL scores and SAS anxiety scores（P 〈 0.05）. In addition, the nursing based on early cardiac rehabilitation group was significantly improved in QOL and SAS anxiety scores（P 〈 0.05）, when compared with the control group. Conclusions This study has demonstrated that the nurse based early cardiac rehabilitation is effective in increasing selected aspects of a general QOL and improved the anxiety situation in elderly patients with CVD. It is worthwhile to be widely used in clinical practice.
