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 investigate a new automatic inverse optimal solution based on VMAT optimization model and verify its result.Methods A variant of the new automatic inverse optimal solution was proposed in this study,which provided a solution to calculate treatment plan with the minimized number of beams and the minimized levels of their intensities on the basis of VMAT optimization model by customized software tools.The verifications were evaluated on the simulated head-neck phantom by dosimetric parameters.Results Compared with conventional IMRT/VMAT treatment plans,the adaptive optimization program(AOP)plan showed that plan20/40(20 fields with totally 40 sub-fields,m=2)made the best achievement and it was clinicable.Conclusions The proposed new optimization technique provides an effective way to reach an inverse treatment plan with the best compromise and less sub-fields compared with IMRT/VMAT plans.

Objective To evaluate the relationship between ambulatory arterial stiffness index (AASI) and intracranial and extracranial arterial stenosis in 146 patients with ischemic cerebrovascular disease. Methods Degree of intracranial and extracranial arterial stenosis in 146 patients with ischemic cerebrovascular disease was assessed by CT angiography (CTA). Then all patients were divided into 4 groups according to the numbers of branches with stenosis: no stenosis group, 1 branch group, 2 branches group, and 3 and more than 3 branches group. Dynamic blood pressure was monitored to calculate the AASI. Results There was no significant difference of AASI among the extracranial arterial stenosis groups (P=0.614). AASI was positively correlated with the degree of intracranial artery stenosis (r=0.743, P<0.05), and with 3 and more intracranial artery branches stenosis (r=0.797, P<0.05). Conclusion AASI is closely correlated with the degree and numbers of branches of intracranial artery stenosis.

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.

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 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.

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.
