China Tropical Medicine 2023;23(6):672-
Abstract: Objective To report the clinical characteristics and genetic test results of two children with neurofibromatosis type 1 (NF1), and to provide reference for the comprehensive diagnosis-treatment and follow-up plans of NF1 patients based on the existing diagnosis and treatment progress of NF1. Methods Two children with NF1 admitted to the Department of Children's Medicine, Haikou people's Hospital in May and June 2022 were selected to analyze the clinical data of their clinical manifestations, laboratory examination, genetic test results, diagnosis and treatment and follow-up retrospectively. Results Two children had typical clinical manifestations, such as café-au-lait spots, axillary freckles, intraocular iris hamartoma. Venous blood was collected from case 1 and his parents for NF gene test, and a new mutation of c.4084C>T in the NF1 gene was found, and their parents did not have the pathogenic gene; the venous blood of the children in case 2 was tested for whole-exome gene analysis, and a heterozygous nonsense variant c.910C>T:p.R304 on the NF1 gene was found, , which was verified by Sanger sequencing to be inherited from his mother, his mother has café-au-lait spots and brain glioma, and has undergone surgery to remove the brain glioma, but has not undergone chemoradiotherapy or targeted therapy. No neurological malignancies were detected in either of the two children at follow-up until July 2022. Conclusions The clinical manifestations of NF1 are relatively typical, genetic testing is conducive to determine its classification, and regular follow-up review can help to detect and treat malignant tumors early, thus improving the patient's quality of life.

Objective: To construct attenuated salmonella typhimurium haboring an eukaryotic co-expression plasmid encoding TIP30 and human IFN-? gene and observing its effect on the growth of adenoid cystic carcinoma. Methods: The TIP30 and human IFN-? genes were amplified by PCR and inserted into eukaryotic expression vector pCI-neofor the construction of expression plasmids pCI-TIP30 and pCI-IFN, respectively. A co-expression plasmid pCI-TIP30/IFN was constructed by linking TIP30 and human IFN-? gene using the sequence of internal ribosome binding sequence (IRES). Three recombinant expression plasmids were transformed into an attenuated AroA'autotrophic mutant of salmonella typhimurium SL7207, the resultant bacteria were used to infected murine macrophage in vitro and the expressed products were detected by Western blot and ELISA, respectively. Tumor growth was observed by oral administration of the recombinant salmonella typhimuriums to the nude mouse with adenoid cystic carcinoma. Results: Murine macrophage infected with recombinant salmonella transformed with both plasmids pCI-TIP30 and pCI-TIP30/IFN could express TIP30 protein, and murine macrophage infected with recombinant salmonella transformed with pCI-IFN or pCI-TIP30/IFN could secret human IFN-? in the culture supernatant. Attenuated salmonella typhimurium and three constructed recombinant salmonella typhimuriums all had evident inhibition onthe tumor growth in nude mouse with adenoid cystic carcinoma. Conclusion: The recombinant attenuated salmonella typhimuriums haboring plasmid pCI-TIP30, plasmidpCI-IFN and co-expressing plasmidp-CI-TIP30/IFN were successfully constructed, which could inhibit the growth of adenoid cystic carcinoma in nude mouse.

Sirtuin 1 (SIRT1),the Ⅲ class deacetylation enzyme,is a kind of NAD + dependent histone deacetylation enzyme.The role of SIRT1 in tumor has the duality.It can inhibit inflammation,tumor angiogenesis and interact with tumor related gene to inhibit tumor development.However,it can also regulate tumor related genes,and epithelial-mesenchymal transition,promote tumor cell proliferation and tolerance of radiotherapy and chemotherapy,and maintain the stemness of cancer stem cells to promote tumor proliferation,invasion and metastasis.

BACKGROUND: At present, bone remodeling biological model study usually applys finite element method combing with computer technique to simulate and predict bone quantity or bone structure. In this study the author integrate inversion method with animal experiment to establish a quantification bone remodeling biological model of in vivo bone tissue in real stress environment.OBJECTIVE: To set up a quantification biological model of bone growth and remodeling adaptation, which integrates animal experiments, parameter inversion identification of mathematical functions, and technique of computer simulation. DESIGN, TIME AND SETTING: The experiment was accomplished in Animal Experiment Center of Dalian Medical University in October 2002.MATERIALS: 60 female Sprague Dawley mice of 6-week old were used in this study. Challenger double-energy X ray bone density device was provided from DMS Company, France. Sensation l6 CT machine was provided from Germany Siemens Company.METHODS: 60 mice were randomly divided into two groups: i 5 animals were in normal control groups. 45 in experiment groups. By designing a new animal experiment, we investigate the effects of stress environments on bone growth and remodeling of rapid growing rats and gather the bone mineral density (BMD) of proximal femur in the same interval for the unknown parameters (B and K) inversion of bone growth and remodeling equation to create the femur three-dimension geometrical model based on CT images. MAIN OUTCOMING MEASURES: Body weight of animal, bone density and CT imagine of proximal femur. RESULTS: Body mass in the experiment group and control group was increased with the rat growing; BMD in the control group and overloading group was also increased with the rat growing; but BMD in the unloading group was decreased in the fifth week. Inversion and experimental data showed that parameter B was rapidly decreased as compared to time, and it was closed to zero in the 10th week. Parameter K was rapidly increased as compared to time. and it was gradually increased from the 5th to the 10th weeks, moreover, it was closed to the horizontal line after 10 weeks. This predicted that rapid growth was over, and bone reconstitution and absorption came into another balance cycle. CONCLUSION: The thought and method used in the model creating in.this paper provide clue and reference to establish human model of bone growth and remodeling.

Objective To determine whether the supplementation of thyroid hormone(TH)improves β-adrenoceptors(β-AR)density and expression of peripheral blood lymphocyte in elderly patients with chronic heart failure(CHF). Methods A total of 42 elderly patients with advanced CHF(NYHA classⅢorⅣ)due to dilated cardiomyopathy(DCM)or ischemic cardiomyopathy (ICM)were randomly divided into a treatment group and a control group.Low-dose L-thyroxine(LT50)was added to the treatment group,both groups had routine anti-heart-failure treatment.Before and after 1 month of treatment,125I-Pindolol radioligand binding assay was used to measure β-AR in peripheral lymphocytes.Reverse-transcriptase polymerase chain reaction(RT-PCR)was used to measure β1-AR expression in peripheral lymphocytes. Results The density and expression of β-AR of lymphocytes in patients with CHF due to ICM or DCM were lower than those in normal health people.and the serum TH level in patients with CHF was lower than that in normal health people.The L-T4 administration induced an up-regulation of β-AR density and expression in peripheral lymphocytes. Conclusions Thyroxine administration induces an up-regulation of β-AR density and expression in peripharal lymphocytes.

Objective To investigate the correlation between the clinical pathological factors and the expression of EGFR, HER2 and HER3 in non-small cell lung cancer tissues. Methods The expression of EGFR, HER2 and HER3 in non-small cell lung cancer tissues was detected by MaxVision immunohistochemical. The relationship between the protein expression and the clinical pathologic characteristics was studied. The correlation between the protein expression and the survival was also retrospectively analyzed. Results Increased expression of EGFR, HER2 and HER3 was detected in the NSCLC tissues and their rates were 45.9 % (73/156), 30.8 % (49/156) and 21.4 % (37/156), respectively. There were significant associations between the expression of these proteins and lymph node metastasis, tumor differentiation degree and TNM staging. Conclusions Overexpression of EGFR, HER2, HER3 or all three proteins is a predictor of poor prognosis. Moreover, combined detection of all 3 markers may work better than the individual detection in the prediction of the prognosis to guide the clinical treatment.
