Objective To compare the quality of life at baseline and at 3 months after coronary artery bypass grafting(CABG) and investigate the related risk factors. Methods The prospective study included 121 consecutive patients reaching inclusion criteria and undergoing CABG between June 2009 and May 2016. Health status survey was measured with short form-36(SF-36)at baseline and at 3 months after CAGB. Change of quality of life and influencing factors and quality of life were analyzed. Results Eight domains including physical functioning ,role-physical ,bodily pain,general health,vitality,social functioning,role-emotional and mental health and two component summaries including physical component summary(PCS)and mental component summary (MCS)of SF-36 were significantly improved at 3 months following CAGB(all P<0.01). Moreover,advanced age, women,diabetes mellitus,assisted ventilation time,hospital stay and use of t-PA were relative to the PCS after CAGB. Conclusions The findings demonstrate quality of life is significantly improved at 3 months post CAGB. Advanced age,underlying disease,serious disease,women and lower PCS score prior to CAGB are linked with low PCS after CAGB.

Objective To detect the serum lipids levels in the subjects aged 40 years and over in the Guangxi Bai Ku Yao population. Methods A total of 485 subjects of Bai Ku Yao and 501 Han people aged 40 years and over were surveyed by cluster sampling methods. Informations on demography, diet and lifestyle were collected by standard questionnaires. Blood pressure, height,weight, waist circumference, serum lipids and apolipoproteins (apo) were measured, and body mass index (BMI) was calculated. Results Education level, height, weight, BMI, waist circumference,blood pressure levels, hypertensive prevalence, and the intakes of total energy, total fat, total protein, dietary cholesterol, and salt were higher in Han than in Bai Ku Yao (P<0.05 or P<0.01),whereas physical activity level, and the intakes of carbohydrate, vegetal protein, and total dietary fiber were higher in Bai Ku Yao than in Han (all P<0.001). The serum levels of total cholesterol,high-density lipoprotein cholesterol, low-density lipoprotein cholesterol, apo A1, and apo B were significantly lower in Bai Ku Yao than in Han [(4. 43±0. 90)vs. (4.96±1.04)mmol/L, P<0. 001;(1.73±0. 42) vs. (2.01±0. 49) mmol/L, P<0. 001;(2. 62±0. 75) vs. (2. 72±0. 78)mmol/L, P<0. 05;(1. 36±0. 33) vs. (1. 48±0. 24)g/L, P<0. 001;and (0. 86±0.23) vs. (0. 95±0. 22)g/L,P<0. 001 ;respectively]. There were no significant differences in serum triglyceride level and the ratio of apo Al over apo B between the two ethnic groups (P>0. 05). Conclusions There are significant differences in lipids levels and the risk factors between Bai Ku Yao and Han populations, which might result from different dietary habits, life styles, and physical activities.

The protein production system using a baculovirus Antheraea pernyi nucleopolyhedrovirus (AnpeNPV) as a gene expression vector and its host insect as a natural bioreactor was successful established and its excellent performance in the protein production has been demonstrated. In this paper, the system is used to produce recombinant human epidermal growth factor (rhEGF), which have been widely used in medical and cosmetic treatment. A recombinant AnpehEGF virus has been constructed by replacing the viral polyhedrin gene with the rhEGF gene, and then injected it to Samia cynthia ricini pupae. Amplification and expression of rhEGF gene in the pupae was clearly detected by PCR, Western blot and ELISA analyses. These analyses have also revealed that rhEGF in the pupae was significantly increased at 6 days post-infection, and reached maximum level at the 12th day. The concentrations of rhEGF were 19.77, 24.90, 618.59 and 1 952.46 ng/g pupae at 3, 6, 9 and 12 days post-infection, respectively. However, the rhEGF concentration reduced at later stage (days 15). The rhEGF in the pupae could be purified using ammonium sulfate precipitation and Ni-NTA agrose affinity chromatography. Results demonstrate that Samia cynthia ricini pupae can be used as a bioreactor to produce rhEGF and, if successfully improved, will be a novel method of rhEGF production with lower cost and more efficient.

Hepatocellular carcinoma (HCC) is the most common primary liver malignancy and is the fourth-leading cause of cancer-related deaths worldwide. HCC is refractory to many standard cancer treatments and the prognosis is often poor, highlighting a pressing need to identify biomarkers of aggressiveness and potential targets for future treatments. Kinesin family member 2C (KIF2C) is reported to be highly expressed in several human tumors. Nevertheless, the molecular mechanisms underlying the role of KIF2C in tumor development and progression have not been investigated. In this study, we found that KIF2C expression was significantly upregulated in HCC, and that KIF2C up-regulation was associated with a poor prognosis. Utilizing both gain and loss of function assays, we showed that KIF2C promoted HCC cell proliferation, migration, invasion, and metastasis both in vitro and in vivo. Mechanistically, we identified TBC1D7 as a binding partner of KIF2C, and this interaction disrupts the formation of the TSC complex, resulting in the enhancement of mammalian target of rapamycin complex1 (mTORC1) signal transduction. Additionally, we found that KIF2C is a direct target of the Wnt/β-catenin pathway, and acts as a key factor in mediating the crosstalk between Wnt/β-catenin and mTORC1 signaling. Thus, the results of our study establish a link between Wnt/β-catenin and mTORC1 signaling, which highlights the potential of KIF2C as a therapeutic target for the treatment of HCC.
