To screening out Chinese vaccine candidate against HIV-1, Chinese vaccine strain 282E4 of fowlpox virus was used as the vector to construct the recombinant fowlpox virus (rFPV) coexpressing gp120 of Chinese HIV-1 strain and IL-18, and the recombinant virus was indentified by PCR and Western blot. The specific DNA fragment could be amplified by PCR from the genome of rFPV. Western blot analysis showed that gp120 and IL-18 could be expressed not only in chicken embryo fibroblast (CEF) cells infected by rFPV, but also in mammalian cells infected by rFPV. After the recombinant fowlpox virus was inoculated into BALB/c mice, the spleen specific CTL activities and serum antibodies in the immunized mice were detected, which demonstrated that the rFPV had good immunogenicity and could induce BALB/c mice to produce specific humoral and cellular immunity. IL-18 palyed the role of immunoadjuvant. The study lays the basis on the preparation of genetic engineering live vector vaccine against HIV-1.

An enzyme-displaying yeast as a whole-cell biocatalyst is an alternative to immobilized enzyme, due to its low-cost preparation and simple recycle course. Here, lipase-displaying Pichia pastoris whole-cell was used as a biocatalyst to synthesize diisooctyl adipate in the non-aqueous system. The maximum productivity of diisooctyl adipate was obtained as 85.0% in a 10 mL reaction system. The yield could be reached as high as 97.8% when the reaction system was scaled up to 200 mL. The purity obtained is 98.2% after vacuum distillation. Thus, the lipase-displaying P. pastoris whole-cell biocatalyst was promising in commercial application for diisooctyl adipate synthesis in non-aqueous phase.

Abstract?AlM:To investigate the influence of lOL refractive index ( Rl ) on measurement of straylight following cataract surgery.?METHODS:ln this case-control study, 77 eyes of 77 age-related cataract patients who underwent cataract phacoemulsification with posterior chamber aspherical arylic lOL implantation surgery in the Eye Hospital of China Medical University from Aug 2013 to Mar 2014, with a best corrected visual acuity ( BCVA) of 0. 5 or better, were classified into 3 groups randomly using 3 types of lOL: Tecnis ZCB00 Group ( Rl = 1. 47, 22 eyes of 22 subjects); Hoya PY60AD Group ( Rl=1. 52, 24 eyes of 24 subjects);Alcon SN60WF or lQ Group ( Rl=1. 55, 31 eyes of 31 subjects ) . BCVA, pupil size, astigmatism, axial length, intraocular straylight were measured respectively.? RESULTS: Age, axial length, BCVA, pupil size, astigmatism of the three groups were not significant difference (P>0. 05). The straylight of Tecnis, Hoya, lQ group were 1.04±0. 15, 1. 19±0. 14, 1. 14±0. 18. Straylight levels had significant differences among three groups ( F=5. 352, P = 0. 007 < 0. 05 ). There was no significant correlation between BCVA and straylight value (r=-0. 133,P=0. 124>0. 05).?CONCLUSlON:Patients chosen the higher Rl lOL may have a higher straylight level after the surgery.

A fermentation system composed of four airlift suspended-bed bioreactors in series and with a total working volume of 4800 mL was established. Continuous ethanol fermentation using self-flocculating yeast SPSC01, a fusant from Saccharomyces cerevisiae and Schizosaccharomyces pombe, and two-stage enzymatic hydrolyte of dry milling corn powder, was continuously run for 120 days. All of the backset distillage collected after distilling the final beer was used to mix the corn powder and no any other wastes except the solid residue of corn powder was discharged from the fermentation system, which guaranteed the distillage to be recycled at its maximum. The experimental results revealed that both ethanol and residual sugar in the final beer could be maintained relatively stable with their average levels of 93.6 and 7.9 g/L, respectively when the fermentation system was operated at the dilution rate of 0.05 h(-1). Parameter oscillations reported previously were also observed for the first and second bioreactors, but were effectively attenuated thereafter, which indicated that high yeast cell concentrations resulted from the self-immobilization of this special self-flocculating strain contributed to damp these oscillations. The monitoring of residual nitrogen and phosphor indicated that the accumulations of these nutritional elements occurred and the amount of these inorganic salts supplemented in the substrate should be decreased properly.

Objective The study aims to investigate the prevalence of gestational diabetes mellitus (GDM) among pregnant women in Tongzhou district of Beijing and its related risk factors. Methods Information of 34 637 singleton pregnancies delivered in a maternal and child health care hospital in Tongzhou district of Beijing were collected from January 1, 2013 to December 31, 2017. GDM prevalence of pregnant women were calculated. Multivariable logistic regression analysis was used to analyze the association between GDM and its related factors. Results The prevalence of GDM in 34 637 singleton pregnant women in Tongzhou district of Beijing was 23.2% (8 034/34 637). Multivariate analysis showed that advanced maternal age(aOR=1.87, 95% CI: 1.71-2.05), high level of education(aOR=1.19-1.23), delivering during 2016-2017(aOR=1.46, 95% CI: 1.38-1.55), macrosomia(aOR=1.27, 95% CI: 1.02-1.59), history of cesarean section(aOR=1.18, 95% CI: 1.08-1.30), history of spontaneous abortion(aOR=1.23, 95% CI:1.10-1.37), history of induced abortion(aOR=1.08, 95% CI:1.01-1.14), family history of diabetes(aOR=1.51, 95% CI:1.26-1.83), multipara(aOR=1.24, 95% CI:1.15-1.34), pre-pregnancy overweight(aOR=2.02, 95% CI:1.89-2.15), pre-pregnancy obesity(aOR=3.11, 95% CI:2.81-3.43)and conceived by assisted reproductive technology(aOR=1.47, 95% CI:1.03-2.10)were the independent risk factors for GDM. Conclusions Prevalence of GDM is high in pregnant women in Tongzhou district of Beijing. Health education before and during pregnancy should be carried out to monitor and prevent the occurrence of GDM in time to ensure maternal and child health.

Purpose: Gastric cancer (GC) has high morbidity and mortality and is a serious threat to public health. The flavonoid compound vitexin is known to exhibit anti-tumor activity. In this study, we explored the therapeutic potential of vitexin in GC and its underlying mechanism. Materials and Methods: The viability, migration, and invasion of GC cells were determined using MTT, scratch wound healing, and transwell assays, respectively. Target molecule expression was determined by western blotting. Tumor growth and liver metastasis were evaluated in vivo using nude mice. Protein expression in the tumor tissues was examined by immunohistochemistry. Results: Vitexin inhibited GC cell viability, migration, invasion, and epithelial-mesenchymal transition (EMT) in a dose-dependent manner. Vitexin treatment led to the inactivation of phosphatidylinositol-3-kinase (PI3K)/AKT/hypoxia-inducible factor-1α (HIF-1α) pathway by repressing HMGB1 expression. Vitexin-mediated inhibition in proliferation, migration, invasion and EMT of GC cells were counteracted by hyper-activation of PI3K/AKT/HIF-1α pathway or HMGB1 overexpression. Finally, vitexin inhibited the xenograft tumor growth and liver metastasis in vivo by suppressing HMGB1 expression. Conclusions Vitexin inhibited the malignant progression of GC in vitro and in vivo by suppressing HMGB1-mediated activation of PI3K/Akt/HIF-1α signaling pathway. Thus, vitexin may serve as a promising therapeutic agent for the treatment of GC.

OBJECTIVETo explore the effect of CMV gB genotypes on viral load and treatment time in patients with CMV infection after hematopoietic stem cell transplantation (HSCT).

METHODSViral load was detected by real-time (RT) quantitative polymerase chain reaction (PCR) (Q-PCR), CMV gB genotypes by PCR restriction fragment length polymorphism (RFLP) (PCR-RFLP) in 115 patients with CMV infection (CMV-DNA positive) after HSCT during July 2004 and May 2010.

RESULTS(1) The distribution of CMV gB genotypes in HSCT recipients were as following: gB1, 42/115 (36.52%); gB2, 3/115 (2.61%); gB3, 43/115 (37.39%); gB4, 2/115 (1.74%). 20 patients (17.39%) had a combination of 2 different CMV genotypes and 5 patients (4.35%) had a CMV variant that lacked an RsaI digestion site, herein named gB5. (2) The median viral load were 2.7×10(3)(1.81×10(3) ∼ 6.03×10(4)) in gB1, 4.0×10(3) (1.32×10(3) ∼ 6.39×10(4)) in gB3 and 1.2×10(4)(2.28×10(3) ∼ 6.50×10(5)) in mixed gB. There was no statistical difference in viral load between gB1 and gB3 (P > 0.050). There was significantly statistical difference in viral load between single-gB (gB1 or gB3) and mixed-gB (P < 0.05). (3) The median treatment time was 17 days in mixed-gB and 14 days in single-gB. There was significantly statistical difference between two groups (P < 0.05). Conclusion gB genotype may have an impact on CMV DNA load and treatment time in HSCT recipients with CMV infection.

OBJECTIVETo investigate the clinical features, differential diagnosis and management of congenital stenosis of external auditory canal (CSEAC) with cholesteatoma.

METHODSThe clinical information for 10 cases of CSEAC with cholesteatoma was retrospectively reviewed.

RESULTSThe patients' ages ranged from 4.75 to 22 years (average 12 years). The diameter of the external auditory canal (EAC) was < 2 mm. All 10 ears had a history of postural fistulae or sinuses. Bone erosion of EAC was distinctly shown in high-resolution computed tomography (HRCT) of all cases, as well as soft tissue masses, which led to enlargement of the bony canals. All patients underwent canaloplasty; eight ears received hearing reconstructions at the same time. Cholesteatoma in EACs was confirmed during the operations, accompanied by compression and destruction of the post-superior and/or inferior bony wall. Postoperative pathologic examinations proved the diagnosis of cholesteatoma, and excluded any tissue of bronchial cleft cyst or fistula. After a follow-up 1 to 3 years, no recurrent cholesteatoma was found in any of the 10 cases. All reconstructed EACs were clean and smooth. The hearing levels in the eight ears that received hearing reconstructions improved 20 - 35 dBHL.

CONCLUSIONSIn CSEAC with cholesteatoma, the bony wall of EAC is most commonly involved. This involvement will lead to bone erosion of the EAC and may subsequently lead to the formation of postural or cervical sinuses. HRCT of temporal bone can show characteristic signs of soft tissue mass in EAC, with adjacent bone erosion.
