Cytology in China developed from nothing and underwent a long journey from gynecologic cytology to that of all organs, laying a solid foundation for new developments in the 21st century. Thyroid fine-needle aspiration (FNA) was primarily developed in an endocrinology department and then in the clinical laboratory department or pathology department in the 1970–80s. Wrights staining is popular in endocrine and clinical laboratory departments, while hematoxylin and eosin staining is common in pathology. Liquid based cytology is not common in thyroid FNA cytology, while BRAFV600E mutation analysis has been the most popular molecular test. The history and practice of thyroid FNA practice in China were reviewed based on retrospective study of the practice in Qilu Hospital of Shandong University.

We displayed four types of Solanum nigrum metallothionein (SMT) for the first time on the surface of Saccharomyces cerevisiae using an α-agglutinin-based display system. The SMT genes were amplified by RT-PCR. The plasmid pYES2 was used to construct the expression vector. Transformed yeast strains were confirmed by PCR amplification and custom sequencing. Surface-expressed metallothioneins were indirectly indicated by the enhanced cadmium sorption capacity. Flame atomic absorption spectrophotometry was used to examine the concentration of Cd2+ in this study. The transformed yeast strains showed much higher resistance ability to Cd2+ compared with the control. Strikingly, their Cd2+ accumulation was almost twice as much as that of the wild-type yeast cells. Furthermore, surface-engineered yeast strains could effectively adsorb ultra-trace cadmium and accumulate Cd2+ under a wide range of pH levels, from 3 to 7, without disturbing the Cu2+ and Hg2+. Four types of surfaceengineered Saccharomyces cerevisiae strains were constructed and they could be used to purify Cd2+-contaminated water and adsorb ultra-trace cadmium effectively. The surface-engineered Saccharomyces cerevisiae strains would be useful tools for the bioremediation and biosorption of environmental cadmium contaminants.

In this paper, the undercut structures were fabricated by microtransfer printing of metal films on the surface of photoresist combined with UV exposure and photoresist film developing. The patterned metal films were used as mask to realize the selective UV exposure of photoresist firstly. The undercut structures, which consist of the top metal films and the patterned bottom photoresist, formed in the subsequent developing process because of the lateral dissolving of photoresist at the edge of the unexposed regions. The method proposed in this paper has wider tolerance to the changing of the patterning parameters, but without effect on the patterning resolution since the metal film was used as the top layer. The undercut structures were used as separators to pattern passive-matrix display of organic light-emitting diodes (OLEDs). No visible difference of the device performance was observed compared with the OLEDs patterned by the shadow mask.

In this paper, distillers’ grains biochar (DGBC) was facilely gained by processing the distillers’ grains producedin Chinese Baijiu brewing, and the DGBC was used to modify BiOCl. The prepared DGBC/BiOCl compositephotocatalysts show elevated visible light-driven catalytic performance. X-ray diffraction (XRD)and scanning electron microscope (SEM) suggest the presence of DGBC affects the crystal growth andmicroscopic morphology of BiOCl. The low-temperature electron paramagnetic resonance (EPR) testaffirms more oxygen vacancies (OVs) exist in the DGBC/BiOCl composite photocatalysts. The 0.75-DGBC/BOC photocatalyst holds the highest efficiency for removal of rhodamine B (RhB), tetracycline(TC) and Cr (VI) compared with BiOCl, commercial TiO2 (P25) and other DGBC/BiOCl composites. Giventhe experimental results, the enhanced visible light responsive performance originates from the richOVs introduced by the modification of BiOCl with DGBC and the higher separation rate of photoexcitedcarriers.
