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.

Objective To study the risky factors related to postoperative mortality after surgical intervention for intra-ventricular hemorrhage (IVH).Methods The clinical data of 142 IVH patients aged from 19 to 86 years with 77 male and 65 female were collected from 2007 to 2010 for retrospective analysis with SPSS version 13.0 package.Multi-factorial Logistic regression analysis and mono-factorial x2 analysis were used to find out the risk factors related to post-operative death. Results Of 142 patients,48 (33.8％) died.Mono-factorial analysis demonstrated that the risk factors of death after surgical intervention to IVH were elderly age ( ＞ 65 years),history of hypertension,low GGS score,intra-ventricular diffuse bleeding,preoperative obstructive hydrocephalus and coagulation abnormality,postoperative central high pyrexia and central diabetes insipidus,postoperative hemorrhage of alimentary tract,pulmonary infection,and drainage after operation ≥7 days ( P ＜ 0.05 or P ＜ 0.01 ).Multi-factorial Logistic regression analysis,on the other hand,revealed the independent factors associated with postoperative IVH mortality were postoperative central high fever,preoperative obstructive hydrocephalus (P ＜ 0.01 ); drainage after operation ≥7 days,postoperative pulmonary infection,elderly age,low GCS score,intra-ventricular diffuse bleeding and history of hypertension ( P ＜ 0.05 ). Conclusions General condition of patients with IVH and CT findings are likely related to mortality,and active prevention against various complications is the crucial approach to lowering postoperative mortality and improving prognosis.

Objective To study the action of puerarin on Caspase-3 and Bcl-2 expression of hippocampal CA1 neurons in ovariectomized rats, and explore its mechanism. Methods SD female rats were randomly assigned into sham operation group, model group, premarin group and puerarin groups (120, 60, 30 mg/kg). The model group and sham operation group were injected NS intraperitoneally, other groups were treated with corresping drugs for 30 d. Immunohistochemistry and RT-PCR were used to determine Caspase-3 and Bcl-2 expression of hippocampal CA1 neurons. Results Caspase-3 expression of hippocampal CA1 neurons was significantly decreased in high-dose puerarin group (P <0.05). Bcl-2 expression of hippocampal CA1 neurons was significantly increased in high- and medium-dose puerarin groups (P<0.05, P<0.01). Bcl-2 mRNA level of hippocampal CA1 neurons in high-dose puerarin group was significantly increased (P<0.05). Conclusion Puerarin can decrease Caspase-3expression and increase Bcl-2 expression of hippocampal CA1 neurons in ovariectomized rats, and has protective effect on neuronal structure.

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.

Objective To investigate the in-stent restenosis after vertebral artery ostium stenting (VAOS),and to determine the risk factors for in-stent restenosis. Methods Respective analysis of clinical data of 775 cases received VAOS in Xuan Wu Hospital of Capital Medical University from Jan. 2006 to Dec. 2012. Severe stenosis of vertebral artery ostium were diagnosed by DSA,and followed-up by ultrasound. The risk factors were assessed by COX analysis for in-stent restenosis ≥50%. Results This study included 775 patients. Surgical success rate was 99. 87%(n=774),technique success rate was 99. 48%(n=771 ). Two patients had cerebral hemorrhage after operation,one of them was dead. Four patients had cerebral infarction. The mean follow-up period was 12 months. The restenosis rate was 35. 89%(234/652 ). 79. 91% of restenosis occurred within 12 months after operation. COX analysis showed the vessels diameter after stenting was the independent predictors of in-stent restenosis (P<0. 01). The in-stent restenosis rate of drug-eluting stents was lower than metal-bare stents (HR 0. 532,95%CI 0. 397-0. 713,P<0. 01). Conclusion The in-stent restenosis was peculiarly prone to the smaller vessels diameter after VAOS. Drug-eluting stents were superior to metal-bare stents in preventing in-stent restenosis.

Methods: A total of 120 patients with gastrointestinal cancer treated in our department from January 2017 to January 2018 were randomly divided into 2 groups: the fire moxibustion group and the conventional group. The conventional group and the fire therapy group were treated with basic treatments such as anti-cancer and nutritional support. The conventional group added Sini-Moxibustion to the basic treatment, and the fire therapy group added"Sini-Moxibustion"therapy for a period of 1 month. Tthe indicators of the 2 groups of patients with Piper fatigue scale and grade, quality of life, symptoms of yang deficiency symptoms, clinical efficacy and blood tests of patients with chemotherapy were evaluated. Results: After the treatment, the degrees of fatigue in the fire moxibustion group was lower than that in the conventional group with statistically significant difference ( χ2 =4.24, P =0.037 ＜ 0.05). The scores of improvement in the quality of life scale and five subscales in the fire moxibustion were higher than those in the conventional group with statistically significant difference (P ＜ 0.01), and the improvement score of the body yang deficiency in the fire moxibustion group was greater than that of the conventional group (P ＜ 0.01). The scores of fatigue, nausea and vomiting, insomnia, anorexia, and diarrhea in the fire moxibustion group were higher than those in the conventional group with statistically significant difference (P ＜ 0.05 or P ＜ 0.01). After treatment, the total effective rate was 76.67％ in the fire moxibustion treatment group, which was higher than the conventional group 91.53％ with statistically significant difference ( χ2 =5.64, P =0.012 ＜ 0.01). Hemoglobin improvement value of 3.92 ± 1.18 in the fire moxibustion group was higher than that of the conventional group 1.02 ± 0.52 with statistically significant difference (t =7.212, P =0.003 ＜ 0.01). Conclusion: Sini-moxibustion can improve the CRF of patients with yangdeficiency gastrointestinal cancer, reduce the symptoms of yang deficiency, improve the quality of life, and increase the hemoglobin content in patients with chemotherapy.

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.
