1.Management of viral encephalitis in children
Chinese Journal of Applied Clinical Pediatrics 2015;30(23):1838-1840
Viral encephalitis is a common pediatric infectious disease of the nervous system,the correct diagnosis, treatment and quality control has always been a challenge;America, British, European, Australia had issued guidelines for the diagnosis and treatment of encephalitis in 2008-2015 ,which had important reference value for guiding clinicians dealing with viral encephalitis, this article integrated above guides and introduced the definition, classification, etiology, accessory examination, handling procedures and treatment of viral encephalitis in children, and the quality control program in the diagnosis and treatment of viral encephalitis in children was preliminarily discussed.

Chinese Journal of Medical Imaging 2009;(6):409-411
Purpose:Occult carcinoma of thyroid ( OCT) is difficult to differentiate from benign thyroid nodules because it is small ( < 1 cm),often asymptomatic,shares similar ultrasonographic characteristics.The aim of this study was to retrospectively review the ultrasound diagnosis and pitfalls of ultrasound in OCT.Materials and Methods: The ultrasonography in 37 cases suspected of OCT were reviewed,analyzed and compared with histopathology.Results: 30/37 (81.1% ) cases (38 nodules) confirmed of OCT were found solid,hypoechogenic nodules in 97.4%,with irregular margins ( 33/38,86.8% ),longitudinal-to-transverse ratio = 1 ( 17/38,44.4% ),minute calcification (19/38,50.0%),decreased flow (36/38,94.7%),and resistance index < 0.7( 30/37,81.1%).7/37 (19.0%) cases of misdiag-nosis included 3 chronic lymphocytic thyroiditis with nodules,2 nodular goiter and 2 collagen nodules.They all had overlapping ultrasonographic features.Conclusion: Those ultrasonographic features were of certain value in OCT.

Neovascular glaucoma ( NVG ) is a series of blinding and intractable eye diseases, which caused by various intraocular or extraocular diseases. The iris and angle neovascularization and vascular membrane fiber contraction may eventually lead to progressive elevation of intraocular pressure and angle closure. Because of complex etiology, the treatment of NVG is intractable and inefficient. Based on the articles published in recent years, we reviewed the progressions of the relevant cytokines and animal models.

We used retrovial vector LXSN to construct recombinant retroviral vector with mutant membrane bound TNF - ? gene. The vectors were introduced into packaging cell line, CRIP cells. The G418-resistant colonies were selected and the supernatants of the colonies were used to determine the virus titers. The titer of virus was 1? 104CFU/ml and the retroviral vectors were used to tranduced the human gastric cancer cell line, MGC-803 cells. The results of southern blot assay showed thai the targel gene had integrated into the genomic DNA of MGC-803T. MGC - 803Tcells were ablc to kill L929 cell line, but the parent cell line showed no cytotoxicily to the cells at all. There was no any variance in the morphological appearance and growlh rate in vilro of MGC-803N and MGC-803T cells. The results of inoculation in nude mice with these cells indicated that MGC-803T cells showed a considerable decrease in size of tumor. These results suggested that the retroviral vectors expressing mulant TNF -? gene were successfully construed. MGC - 803T cells showed cytotoxicily slrongly lo L929 cell line in vilro and lumorigenicity .

Objective:
To investigate the epidemiological characteristics of measles in Jiaxing City of Zhejiang Province in different immunization program periods, so as to provide the evidence for improving prevention and control strategies of measles.
Methods:
Data of measles cases in Jiaxing City from 2005 to 2023 was collected through the Chinese Disease Prevention and Control Information System. Population, temporal, and regional distribution of measles during the periods of pre-expanded immunization program (from 2005 to 2007), expanded immunization program (from 2008 to 2010), and enhanced immunization program (from 2011 to 2023) were descriptively analyzed.
Results:
There were 3 997 measles cases reported in Jiaxing City from 2005 to 2023, with an average annual reported incidence of 4.66/105, showing a decreasing trend (P<0.05). The average annual reported incidence of measles during the periods of pre-expanded immunization program, expanded immunization program, and enhanced immunization program were 22.88/105, 7.24/105 and 0.83/105, respectively. The incidence of measles during different stages of immunization strategies all peaked from March to May. The highest reported incidence was 5.94/105 in Pinghu City and the lowest was 3.92/105 in Tongxiang City. The districts with the highest average annual reported incidence in the periods of pre-expanded immunization program, expanded immunization program, and enhanced immunization program were Nanhu District (31.10/105), Pinghu City (11.10/105) and Jiashan County (1.55/105), respectively. There was spatial clustering of measles in Jiaxing City during the period of pre-expanded immunization program (Moran's I=0.787, P<0.05), with a high-high cluster in Nanhu District.
Conclusions
The reported incidence of measles in Jiaxing City showed a decreasing trend from 2005 to 2023. There was a spatial cluster of measles incidence during the period of pre-expanded immunization program, but no significant clusters during the periods of expanded immunization program and enhanced immunization program.

The cytolytic effect of perforin is a mechanism of anti-virus,killing microbial-infected cells and tumor cells.Perforin is a very important non-specific immune factors in fish.In order to understand the function of perforin,the cDNA of grass carp perforin C-terminal peptide was amplified from grass carp liver and kidney cDNA library.It contains a protein kinase C conserved region 2(C2).The cDNA was connected with pET32a,and transformed to expression bacteria DE3.PFP-C was expressed by a prokaryotic expression system and then purified by affinity chromatography.It showed a significant haemolytic activity when tested with rabbit red cells,the optimal pH for haemolytic activity was 7.5,and its haemolytic function dependents on Ca2+ apparently.
