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.

Objective:To investigate the relationship between TGF-? 1mRNA and acute rejection of small intestinal allografts in rats.Methods:Rats were divided into two groups.Group Ⅰ:Wistar→SD Small intestinal transplantation,Group Ⅱ:Wistar→SD Small intestinal transplantation+CsA.The pathologic changes of allografts at 3 rdday,5 thday,7 thday after operation investigated and the transcription of IL-2,IFN- ?,and TGF-? 1mRNA was detected by semi-quantity RT-PCR.Results:Pathologic change:There was acute rejection at 3 rdday,and became severe at 7 thday in group Ⅰ,and there was only slight rejection at 7 thday in groupⅡ.TIFN-?、IL-2mRNA obviously increased after operation in groupⅠ.But they increased only a little in group Ⅱ.It had statistical significance between the two groups(P

Objective To study the biomechanical strength of calcium phoshphate cement (CPC) in fixating distal radial fractures. Methods A total of 18 human distal radius fracture models were made and randomly divided into three groups: fixed with Kirschner wire (Kirschner group), CPC (CPC group) or CPC combined with Kirschner wire (combination group). Compression test was performed to measure compression rigidity and rotational angle of distal fragment at 100 N and anticompression strength and maximum compression strength at 2 mm displacement. Results Compression rigidity, distal fragment rotation angle in coronal or sagittal plate had no significant statistical difference at 100 N of compression in three groups. Compression strength at 2 mm displacement in CPC group (average 375 N) and combination group (average 386 N) exceeded that in Kirschner group (average 116 N), with significantly statistical difference (P

Objective To compare the clinical efficacy and safety of transurethral plasmakinetic resection of prostate (PKRP) and transurethral resection of prostate (TURP) for benign prostatic hyperplasia (BPH). Methods Two groups of BPH patients (78 patients in each group) were treated by PKRP and TURP,respectively. The clinical efficacy and safety indices were reviewed and compared for both intra- and inter-groups. Results In PKRP group,the operative time,intraoperative bleeding, the rates of postoperative temporary urinary incontinence (within 2 months) ,secondary hemorrhage (within 4 weeks),and urethral stricture (within 3 months) were ( 64?21) min, ( 247?84) ml, 26. 9% ( 21/78 ) , 1. 3% ( 1/78 ) and 2.6% (2/78) ,respectively; while in TURP group, these parameters were (78?18) min, (432?132) ml, 48.7% (38/78) , 10. 3% (8/78) and 12. 8% ( 10/78 ), respectively; there were significant differences between the 2 groups (P 0. 05). Conclusions PKRP and TURP have similar efficacy in the treatment of BPH,but PKRP is safer than TURP. Thus,PKRP is a better treatment option for BPH.

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.

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.
