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 evaluate the clinical application of VAMTS in lung cancer patients.Meth- ods Between May 2004 and June 2005,30 patients with lung cancer applied VAMTS.The minimalthoracto- my from 8 to 10 cm was made at fourth or fifth intercostal space and lobectomy was undergone for convertion- al or dedicated endoscopic instruments.Some mediastinum lymphnode(MLN)resection were performed.Re- suits Operative time from 50 to 210 minutes and average 123 minutes.The intraoperative blood loss is less, and without blood transfusion.The average drawing duct time is 3.9 days.No death caused by operation and postoperative syndromes.Conclusion VAMTS wounds much less,operative scale lumination is better,opera- tive time shorter,blood loss less,and recover more quickly.The hospitalization time is shorter.The VAMTS with MLNR is regarded as an implement of lung cancer remedy,fits to stageⅠ-Ⅱ,diameter

Objective To investigate the effects of spine region of interest (ROI),tracking range,and real-time image contrast ratio on the positioning errors of cyberknife.Methods The LTT dynamic phantom was used to develop a spine tracking plan and perform treatment,and the target positioning system was used to preset the phantom and obtain real-time preset image and positioning error.Based on the realtime preset image,spine ROI,tracking range,and real-time image contrast ratio were changed to observe the changes in positioning error and related parameters.Pearson correlation analysis was performed.Results The change in tracking range did not change the positioning error in spine tracking,and tracking range was not correlated with positioning error (R =0,P =1).The changes in ROI and image contrast ratio did not affect the translation error,but affected the rotation error,especially the rotation error in left-right direction (r =0.533 and 0.693,P=0.002 and 0.026).The image contrast ratio had the most obvious effect,with an amplitude of variation up to 2.2°.Conclusions The change in tracking range does not affect the positioning errors in spinal tracking,but the changes in ROI and image contrast ratio can cause varying degrees of changes in positioning errors,which should be taken seriously in cyberknife treatment.

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.

Objective To detect the expression of Bmi-1 and p16 gene in transitional cell carcinoma of bladder(TCC) tissue and explore its clinical significance.Methods The expression of Bmi-1 and p16 gene were detected by real-time quantitative polymerase chain reaction in 61 cases of TCC tissue and 12 cases of normal bladder tissue.Results The expression of Bmi-1 gene in TCC tissue was significantly higher than that in normal bladder tissue (0.242 ± 0.129 vs.0.031 ± 0.011),and the expression of p16 gene was significantly lower than that in normal bladder tissue (0.059 ± 0.021 vs.0.165 ± 0.029),there was significant difference (P ＜ 0.05).The expression of Bmi-1 and p16 gene were highly correlated with pathological grades,clinical stages and tumor recurrence (P ＜ 0.05 or ＜ 0.01).But there were not correlated with age and gender (P ＞ 0.05).There was a negative correlation between the expression of Bmi-1 gene and p16 gene in TCC tissue(rs =-0.714,P＜ 0.05).Conclusions Bmi-1 gene high expression and p16 gene low expression may be involved in the occurrence and development process of TCC.Bmi-1 may decrease the expression of p 16 gene in some ways,and then lead to the occurrence and development of TCC.

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.

Human bocavirus (HBoV) 1-4 have been detected both in respiratory and stool samples since the first HBoV was discovered in 2005. HBoV-1 is mostly associated with respiratory infection, while HBoV 2-4 are usually associated with intestinal tract infection. A variety of signs and symptoms have been described in patients with HBoV infection, including cough, wheezing, pneumonia, and diarrhea, but the research on pathogenic mechanism of HBoV is limited because HBoV cannot be cultured in vitro due to the lack of appropriate host cells. Three-dimensional epithelial cell culture, reverse genetics, and viral metagenomics are identified as novel tools that may promote the research on pathogenic mechanism of HBoV and the discovery of new viruses. This review summaries currently available diagnostic approaches such as electron microscopy, cell culture, PCR, and immunoassay in order to provide a method reference for indepth research on HBoV.
