2.The significance of electron microscopy in the etiological diagnosis of respiratory tract infection
International Journal of Pediatrics 2021;48(1):6-8
At present, electron microscopy has played a more and more important role in the field of medicine.It is often used in the ultrastructure observation of various systems, mechanism research and clinical diagnosis of diseases.The role of electron microscopy in the etiological diagnosis of respiratory tract infection cannot be ignored, but its related review is less.By using electron microscopy, the morphological characteristics of respiratory tract pathogens can be accurately observed and the new respiratory tract infection pathogens can be classified and screened.In addition, through the combination of samples with patients′ serum and observation of immuno-electron microscopy, the host response to pathogens can also be understood.However, due to the high equipment requirements, technical difficulties, complex operation and other factors, electron microscopy is rarely used in conventional etiological diagnosis, and more used in laboratory basic research.In this paper, the advantages, disadvantages and significance of electron microscopy in the etiological diagnosis of respiratory tract are reviewed.

In order to identify host factors which interact with the movement protein (MP) of Apple chlorotic leaf spot virus (ACLSV), ACLSV MP was cloned into the bait vector pGBKT7 and used to screen a cDNA library of Malus sylvestris cv. R12740-7A, which had previously been constructed by yeast two-hybrid sequencing transformation. The protein functions of the identified host factors were determined according to their gene annotations in GenBank. The result showed that the bait plasmid pGBKT7-MP showed no virulence or self-activating effect on yeast strain Y2H Gold. Sixty-nine interactor proteins were identified, which were divided into the following 10 classes according to their described functions: hydrolases; pathogenesis-related proteins; DNA binding proteins; phosphatases; ligases; proteins with catalytic activity; phenylalanine ammonialyases; peroxidases; NAD binding proteins; and proteins of unknown function. Bioinformatic analysis of gene homology suggested that phosphatases, pathogenesis-related proteins and glyceraldehyde-3-phosphate dehydrogenase A may play an important role in the interaction between virus and host. This study may provide a theoretical basis for the further study of viral pathogenesis and virus-host interaction mechanisms.

Objective:A study was conducted to investigate the effect of Prunella vulgaris sulfated polysaccharide (PVSP) on the expression of angiogenic growth factors (bFGF, VEGF, and IL-8) and angiogenesis in hepatocellular carcinoma. Methods:ELISA as-say was used to observe the effects of PVSP and the negative control drug Lentinan (LNT, non-sulfate radical drug) on secretions of the angiogenic growth factors, namely, bFGF, VEGF, and IL-8, in HepG2 cells in vitro. In an in vivo experiment, the microvessel density in hepatocellular carcinoma tissue sections treated with PVSP and LNT was calculated, analyzed, and compared with the microvessel den-sity in the phosphate-buffered saline (PBS) control. Results:Compared with the PBS control group, PVSP at 200μg/mL inhibited bF-GF secretion (P<0.01), whereas LNT failed to affect bFGF secretion. Neither PVSP nor LNT affected the secretions of VEGF and IL-8. In vivo results showed that PVSP at 200 mg/kg reduced the microvessel density in tumor tissue sections (P=0.03), whereas LNT at 10 mg/kg failed to affect microvessel density. Conclusion:Inhibition of bFGF secretion is a probable mechanism underlying the preven-tive effect of PVSP on hepatocellular carcinoma angiogenesis.

Objective To analyze and assess the major functions of medical APP by investigating its application in self management of chronic diseases. Methods The 3 major functions of APP were analyzed, including data record and condition assessment, medical consultation, and life therapy. Results The medical APP possesses its basic functions for chronic diseases management. However, it lacks of practicality and convenience and its homogenization is severe. Conclusion The APP +hardware +cloud medical management model should be promoted by making use of the Internet + medical technology, the supervision of mobile medical APP should be strengthened, the mobile information management mechanisms of chronic diseases should be perfected, and the self management efficiency of patients with chronic diseases should be improved.

Objective To explore the expression changes of C/EBP homologous binding protein (CHOP)in intermittent hypoxic rats with cognitive function decline and clinical significance.Methods We randomly divided 75 adult male Wistar rats into normal group (NC group),5% intermittent hypoxia group (5% CIH group)and 10%intermittent hypoxia group (10% CIH group),with 25 rats in each.Then the three groups were further divided into 3 d,7 d,14 d,21 d and 28 d subgroups,and each time a subgroup had 5 rats.The control group was exposed to the air while 10% CIH group and 5% CIH group were exposed to CIH for eight hours from 8:00 to 1 6:00 each day. After exposure for 3 d,7 d,14 d,21 d and 28 d,the cognitive function of rats was assessed with Morris water maze, the expression of CHOP in the hippocampus was assayed qualitatively by immunohistochemical technique,and the apoptosis of neurons was detected by TUNEL method.Results ① With prolonged hypoxia,the time of escape latency obviously prolonged,the time spent crossing the target quadrant shortened (P < 0.05 ),and the apoptosis index of hippocampal neurons in the CIH groups was increased gradually compared with those in control group (P <0.05).The above-mentioned indexes changed more significantly in 5% CIH group than in 10% CIH group (P <0.05).②.The expression of CHOP protein at each time point was increased (P <0.05 ).In 10% CIH group it reached the peak at 28 d while in 5% CIH group it decreased after it peaked at 21 d.③ The expression of CHOP in the two CIH groups was positively correlated with apoptosis index and animal escape latency time,but negatively correlated with the target quadrant time.Conclusion Intermittent hypoxia,which is likely to induce the high expression of CHOP and activation of neural CHOP mediated apoptosis,causes cognitive impairment of various degrees.
