With the development of high gravity brewing, yeast cells are exposed to multiple brewing-associated stresses, such as increased osmotic pressure, enhanced alcohol concentration and nutritional imbalance. These will speed up yeast autolysis, which seriously influence beer flavor and quality. To increase yeast anti-autolytic ability, FKS1 overexpression strain was constructed by 18S rDNA. The concentration of β-1,3-glucan of overexpression strain was 62% higher than that of wild type strain. Meantime, FKS1 overexpression strain increased anti-stress ability at 8% ethanol, 0.4 mol/L NaCl and starvation stress. Under simulated autolysis, FKS1 showed good anti-autolytic ability by slower autolysis. These results confirms the potential of FKS1 overexpression to tackle yeast autolysis in high-gravity brewing.

AIM:To evaluate changes in tear film stability and meibomian gland function and the clinic efficacy of three different artificial tears in patients with preoperative dry eye after phacoemulsification.METHODS:All 90 cataract patients (90 eyes) with preoperative dry eye who underwent phacoemulsification randomly divided into three groups (Group A treated with protein-free calf blood extract ophthalmic gel;Group B treated with sodium hyaluronate eye drops;Group C treated with Vitamin A palmitate eye gel).Ocular Surface Disease Index (OSDI), Schimer's I test(SⅠt), tear film break time (BUT), corneal fluorescein staining (FL) and meibography were performed for all patients preoperatively and 7, 30 and 90d postoperatively.RESULTS:No statistical differences existed among the three preoperative groups (P>0.05).Except meibomian gland score, there was no statistical significance among preoperatively and 7, 30, 90d postoperatively of the three groups (P>0.05).At 7d postoperatively, SⅠt and BUT of every group were lower than those before treatment, FL scores and OSDI scores were higher than those preoperative (P<0.05);there were no statistical differences among the three groups(P>0.05).At 30d postoperatively, SIt, BUT, OSDI scores in group A and C were better than in group B, which displayed statistical differences (P<0.05);FL scores in group A were significantly better than in group B and C (P<0.05).At 30, 90d postoperatively, SIt, BUT, FL scores, OSDI scores were better than preoperative results, which displayed statistical differences (P<0.05).There were no statistical differences among the three groups at 90d postoperatively (P>0.05).CONCLUSION:Tear film stability and meibomian gland function were affected by phacoemulsification.Topical application of deproteinised calf blood extract eye gel, sodium hyaluronate eye drops and Vitamin A palmitate eye gel all hase a clearly beneficial effect on subjective symptoms.Deproteinised calf blood extract eye gel and Vitamin A Palmitate Eye Gel had more powerful effect on BUT than sodium hyaluronate, however deproteinised calf blood extract eye gel is more effective in superficial punctuate keratopathy.

Objective To study relationships between myocardial injury and the levels of serum complement C3, C4 and C5b-9 in patients with acute coronary syndrome (ACS). Methods A retrospectively analysis was conducted. 170 ACS patients [including 110 cases of ST-segment elevation myocardial infarction (STEMI) and 60 cases of non-ST-segment elevation acute coronary syndrome (NSTE-ACS)] with ischemic chest pain or chest discomfort onset within the prior 12 hours admitted to the cardiology department of Tianjin Union Medicine Center from January 2014 to July 2016 were enrolled. Thirty-six healthy cases were enrolled as control during the same time. The levels of serum complement C3, C4 and C5b-9 on 1, 3 and 7 days after admission and myocardial function indicators were analyzed. Major adverse cardiovascular events (MACE) and readmission rate were analyzed after 1 year follow-up. The correlation between serum complement levels and myocardial function indicators was analyzed by Pearson correlation analysis. Results ① The levels of serum C3, C4 and C5b-9 on the first day in NSTE-ACS group and STEMI group were significantly higher than control group [C3 (g/L): 1.04±0.33, 1.26±0.35 vs. 0.39±0.21, C4 (g/L): 0.31±0.14, 0.33±0.10 vs. 0.19±0.07, C5b-9 (g/L): 575.46±197.26, 659.26±160.77 vs. 501.40±141.51, all P < 0.05]. There were no changes of serum C3, C4 in NSTE-ACS group, but C5b-9 decreased after a peak (g/L: 700.63±218.42) at 3 days. Serum complements in STEMI group reached peak on the third day [C3 (g/L): 1.37±0.33, C4 (g/L): 0.42±0.12, C5b-9 (g/L): 754.72±136.22]. The levels of serum C4 and C5b-9 in STEMI group were higher than NSTE-ACS group on the third and seventh day. ② The levels of troponin T (TnT), creatine kinase-MB (CK-MB), solution intercellular adhesion molecule-1 (sICAM-1), global registry of acute coronary events (GRACE) scores and percutaneous coronary intervention (PCI) numbers in STEMI group were significantly higher than those in the NSTE-ACS group, which were as opposite as left ventricular ejection fraction (LVEF). However, there were no significant differences in levels of serum N-terminal pro-brain nitric peptide (NT-proBNP), Fibrinogen (Fib), readmission rate and incidence of MACE between STEMI and NSTE-ACS groups. ③ According to GRACE, patients with ACS were divided into low risk group (≤ 108 scores, 26 cases), intermediate risk group (109-140 scores, 61 cases) and highest group (> 140 scores, 83 cases). TnT and sICAM-1 in intermediate risk group were significantly increased as compared with low risk group. Levels of TnT, sICAM-1, C3, C4 and C5b-9 in the highest group were significantly higher than the low and intermediate risk groups, however the lowest LVEF was found in the highest group. ④ It was shown by Pearson correlation analyses that levels of serum C3, C4, C5b-9 were positively correlated with TnT (r value was 0.481, 0.367, 0.292, respectively, all P <0.01), sICAM-1 (r value was 0.298, 0.249, 0.365, respectively, all P < 0.01), but negatively correlated with LVEF (r value was -0.384, -0.260, -0.200, respectively, all P < 0.01). In addition sICAM-1 positively correlated with TnT (r = 0.536, P = 0.000), but negatively correlated with LVEF (r = -0.341, P = 0.001). Conclusions Serum complements activation was found in the acute phase of ACS patients. Serum complement C3, C4 and C5b-9 are involved in the process of myocardial injury, and may reflect severity of myocardial injury and cardiac dysfunction.

OBJECTIVETo dynamically assess drug targeting of Yougui Pill (YP) and Zuogui Pill (ZP) using infrared thermography.

METHODSIn this self-control experiment, five healthy volunteers were recruited. By using infrared thermography 10 to 11 thermal images of different body locations were taken from each participant after they took warm water, YP, ZP, and their dissembled prescriptions at 30, 70, 100, 130, and 160 min, respectively. The heat values in the lower quadrant abdomen, uterus, Du channel, and Shenque (CV8) were statistically analyzed after scanning for 125 times.

RESULTSAdministration of YP and its disassembled prescriptions enhanced the heat value of the locations of the Du channel and Shenque (CV8), but did no enhance the heat value of the lower quadrant abdomen at 30 min. Administration of ZP and its disassembled prescriptions reduced the heat value in the locations of the lower quadrant abdomen, uterus, Du channel, and Shenque (CV8) at each time point.

CONCLUSIONThe drug targeting of ZP and YP focused on the locations of the Du channel and Shenque (CV8), not on the locations of the lower quadrant abdomen or uterus.

Coding region instability determinant (CRD) is one of the influence factors of oncogene c-myc.Coding region instability determinant-binding protein (CRD-BP) can connect with CRD in order to protect CRD from nuclease attack,prevent rapid degradation of c-myc mRNA,and increase c-myc protein content.Beta-transducin repeats-containing protein (β-TrCP) can affect cell growth,differentiation,apoptosis and oncogenesis by regulating multiple signaling pathways and cell cycle.The overexpression of CRD-BP can upregulate the expression of β-TrCP and both of them play important roles in the tumorigenesis,progression,metastasis and invasion of colorectal cancer.

Psoriasis is a chronic,refractory,inflammatory skin disease that occurs in young adults.The traditional animal model cannot simulate the skin characteristics of patients with psoriasis effectively, so it is difficult to be used for in-depth study of psoriasis mechanism. Immortalized human epidermal cells (HaCaT)is a non-tumor,immortalized human epidermal cell which is widely used in the study of dermatosis.HaCaT cells are the best choice for the study of psoriasis mechanism because their immu-nological characteristics and reproductive ability are coincide with the pathological features of psoriasis. This article reviews the specific methods such as establishment of cell method, cytokine and chemo-kine analysisin the pathogenesis study of psoriasis based on HaCaT cells, hoping to provide some thoughts for drug′s pharmacological activity research.
