Research on the regulation of food therapy prescription of Traditional Chinese medicine in treating children′s stagnation based on data mining / 中国实用护理杂志

Objective:Data mining technology was used to analyze the regulation of food therapy prescriptions in treating children′s stagnation.Methods:Collect the therapy prescriptions used for regulating children's stagnation in the Dictionary of Traditional Chinese Medicine Prescriptions, the Complete Record of Dietary Therapy Prescriptions of Traditional Chinese Medicine and the Dictionary of Chinese Medicinal Diet, extract the information of prescription name, composition, etc, and use SPSS 22.0 for frequency analysis, and use Weka for correlation analysis. Results:A total of 99 dietary prescriptions for children with hysteria were included, involving a total of 62 foods, with a total use frequency of 224 times, among which the food with high use frequency were chicken gizzard, japonica rice, hawthorn, etc. The four characteristics of food were mainly concentrated in the flat, the five tastes were mainly concentrated in the sweet, the return channel was mainly concentrated in the spleen and stomach channel, and the effect was mainly concentrated in the absorption of food and tonic deficiency. The main symptoms of the therapeutic prescription for children's accumulation of stagnation were internal accumulation of milk and food and combination of spleen deficiency. The commonly used food combination for children's accumulation of stagnation of milk and food was "fructus amomi - chicken gizzard". The commonly used food combination of children with spleen deficiency and accumulation of stagnation was "lentil bean-yam-japonica rice" and "millet-yam".Conclusions:Traditional Chinese medicine diet prescription for the treatment of children's accumulation of stagnation pay attention to harmony and regulation, sweet and slow tonifying, emphasizing the adjustment of the spleen and stomach, taking into account the regulation of lung, following the "eliminating and supplementing both, according to the cause of treatment" rule, advocate syndrome differentiation of food.

Variant haplophasing by long-read sequencing: a new approach to preimplantation genetic testing workups.

OBJECTIVE: To apply long-read, third-generation sequencing as a part of a general workup strategy for performing structural rearrangement (PGT-SR) and monogenic disease (PGT-M) embryo testing. DESIGN: Prospective study. SETTING: In vitro fertilization unit. PATIENT(S): Couples presenting for PGT-SR (n = 15) and PGT-M (n = 2). INTERVENTION(S): Blastocyst biopsy with molecular testing for translocation breakpoints or mutations (targets). MAIN OUTCOME MEASURE(S): Detailed, parental-phased, single-nucleotide polymorphism (SNP) profiles around targets for selection of informative polymorphic markers to simplify and facilitate clinical preimplantation genetic testing (PGT) designs that enable discrimination between carrier and noncarrier embryos. RESULT(S): High definition of chromosome breakpoints together with closely phased polymorphic markers was achieved for all 15 couples presenting for PGT-SR. Similarly, for the two couples presenting for PGT-M, tightly linked informative markers around the mutations were also simply identified. Three couples with translocations t(1;17)(q21;p13), t(3;13)(p25;q21.2), and t(12;13)(q23;q22) proceeded with PGT-SR, requesting preferential identification of noncarrier embryos for transfer. Following selection of a set of informative SNPs linked to breakpoints, we successfully performed PGT-SR tests, resulting in ongoing pregnancies with a noncarrier fetus for all couples. Similarly, with the use of tests based on informative SNPs linked to the parental mutations, one couple proceeded with PGT-M for maple syrup urine disease, resulting in an ongoing pregnancy with a disease-free fetus. CONCLUSION(S): For couples contemplating clinical PGT, variant haplophasing around the target reduces the workup process by enabling rapid selection of closely linked informative markers for patient-specific test design.

Non-motor symptoms in amyotrophic lateral sclerosis / 西安交通大学学报(医学版)

Amyotrophic lateral sclerosis (ALS) is a degenerative disease of the nervous system caused by the loss of motor neurons in the brain and spinal cord. At present, ALS is considered as a multi-system disease, with both motor and non-motor features. Motor neuron involvement usually begins in a single functional region (medulla oblongata, cervical vertebra, lumbosacral and thoracic vertebra) and gradually spreads throughout the motor system. Non-motor features may be caused by pathological damage from the motor region to the adjacent non-motor region or by other unknown causes. There is no uniform definition of non-motor features of ALS. Sometimes they refer to symptoms caused by damage to the non-pyramidal system, and sometimes they also include ALS syndrome. They can be divided into neuropsychiatric, autonomic, vascular and gastrointestinal dysfunctions. More than 50% of patients with ALS have symptoms of neuropsychiatric disorder, which are extremely heterogeneous. Such clinical heterogeneity is based on neuroimaging, genetics and neuropathology, which has updated the concept of ALS, leading to the present recognition of the spectrum disorder of ALS and frontotemporal dementia. The core features of the ALS diagnosis model should also be multi-axis diagnosis, using three main "diagnostic axes", i.e., axis to define motor neuron symptom variations, axis Ⅱ to define cognitive and behavioral dysfunction, and axis III to define other non-motor symptoms. This paper introduces ALS cognitive and behavioral dysfunction, ALS plus syndrome and other non-motor features associated with ALS so as to improve clinicians' understanding of managing the overall health status of ALS patients, make rational scientific evidence-based decisions and contribute to improving the quality of life of ALS patients.

Improvement of acetic acid tolerance and fermentation performance of industrial Saccharomyces cerevisiae by overexpression of flocculent gene FLO1 and FLO1c / 生物工程学报

Flocculent gene FLO1 and its truncated form FLO1c with complete deletion of repeat unit C were expressed in a non-flocculent industrial strain Saccharomyces cerevisiae CE6 to generate recombinant flocculent strains 6-AF1 and 6-AF1c respectively. Both strains of 6-AF1 and 6-AF1c displayed strong flocculation and better cell growth than the control strain CE6-V carrying the empty vector under acetic acid stress. Moreover, the flocculent strains converted glucose to ethanol at much higher rates than the control strain CE6-V under acetic acid stress. In the presence of 0.6% (V/V) acetic acid, the average ethanol production rates of 6-AF1 and 6-AF1c were 1.56 and 1.62 times of that of strain CE6-V, while the ethanol production rates of 6-AF1 and 6-AF1c were 1.21 and 1.78 times of that of strain CE6-V under 1.0% acetic acid stress. Results in this study indicate that acetic acid tolerance and fermentation performance of industrial S. cerevisiae under acetic acid stress can be improved largely by flocculation endowed by expression of flocculent genes, especially FLO1c.
