Objective To investigate the safety and effectiveness of using low-profile visualized intraluminal support (LVIS) stents for the treatment of aneurysms in the small intracranial vessels (diameter <2.5 mm).Methods Between October 2014 and April 2016,the clinical data of all 30 patients with intracranial saccular aneurysm treated with LVIS stents with the small parent arteries <2.5 mm in diameter in Changhai Hospital,the Second Military Medical University were analyzed retrospectively,including 7 ruptured aneurysms and 23 unruptured aneurysms.The anterior circulation aneurysm accounted for 93.3% (n=28),and the diameters of the parent arteries were 1.6-2.4 mm.The complications associated with surgery,angiography,clinical outcomes,and mid-term follow-up data were analyzed.Results The success rate of stent implantation was 100%.Immediate embolization results:Raymond grade Ⅰ in 12 cases (40.0%),Raymond grade Ⅱ in 11 cases (36.7%),and Raymond grade Ⅲ in 7 cases (23.3%).Complications occurred in 2 cases,including one perforating artery occlusion and one intraoperative rupture.Twenty-five patients accepted the angiographic follow-up (Raymond grade Ⅰ in 21 cases,grade Ⅱ in 3 cases,and grade Ⅲ in 1 case).The follow-up time ranged from 4 to 14 months,with an average of 8.1± 2.6 months.One patient had asymptomatic intracranial artery stenosis in the distal end of the stent.No new neurological dysfunction or death occurred.Conclusion The deployment of LVIS stents in small vessels is safe and feasible,the effect of mid-term follow-up is better.However,a larger sample study and long-term follow-up results are needed.

Objective: To observe the immediate effect of small-angle Tui-Pushing and An-Pressing anti-rotation bone-setting manipulation in improving the correction of braces for adolescent idiopathic scoliosis. Methods: A total of 50 cases of adolescent idiopathic scoliosis were selected and given brace correction first. The whole spine anteroposterior and lateral radiographs were taken, the Cobb angle was measured, and the visual analog scale (VAS) score of pain caused by brace wearing was recorded. After removal of the brace, small-angle Tui-Pushing and An-Pressing anti-rotation bone-setting manipulation was performed once. After treatment, the same brace was put on again to take a whole spine anteroposterior radiograph, the Cobb angle was measured, and the VAS score was recorded. The changes in Cobb angle and VAS score after manipulation were compared, and the immediate efficacy was evaluated. Results: After the manipulation, the Cobb angle was significantly smaller than that before treatment (P<0.01) and the VAS score was significantly lower than that before treatment (P<0.01). Conclusion: Small-angle Tui-Pushing and An-Pressing anti-rotation bone-setting manipulation can improve the immediate efficacy of brace in treating adolescent idiopathic scoliosis and relieve the pain caused by brace wearing at the same time.

Objective:
To explore the effectiveness of spinal guidance exercise on adolescents of mild idiopathic scoliosis, so as to provide an experimental reference and method for promoting adolescents spinal health.
Methods:
From the scoliosis screening, 96 children who met the diagnostic criteria were selected in June 2021, and were divided into the experimental group and the control group, with 48 cases in each group. The experimental group received a 12 week Longji Daoyin exercise training, and the control group received health education, observation and monitoring. Before and after the experiment, the axial trunk rotation (ATR) and scoliosis Cobb angle of the two groups were tested respectively, and the subjective sensation of the patients was measured by Scoliosis Research Society-22(SRS-22) questionnaire.
Results:
After 12 weeks, the ATR and Cobb angles of the experimental group decreased [( 5.02± 2.85,7.59±3.94)°],compared to (7.08±2.84)° and (15.84±2.00)° before intervention( t =14.02, 17.09, P < 0.01 ). Scores of functional activity, self image and mental health in the SRS-22 score increased from (4.65±0.14)(3.49±0.21) and (3.99±0.17) to(4.77±0.14)(4.62±0.13)(4.42±0.13)( t =-4.86,-39.12,-13.92, P <0.01 ). The ATR and Cobb angles of the control group increased from (6.94±2.15)° and (15.82±1.76)° to (8.25±2.49)° and (18.63±3.12)°( t =7.44,8.99, P <0.01), and the scores of self image and mental health in the SRS-22 score decreased from (3.49±0.19) and (4.00±0.15) to (3.44±0.18) and (3.94±0.14)( t =-3.74,-4.39, P <0.05).
Conclusion
Early adolescent idiopathic scoliosis is easy to aggravate during the observation period. Longji Daoyin exercise is of preventive and therapeutic significance.

Objective:To analyze the ultrasonographic features of adenoma of the nonpigmented ciliary epithelium (ANPCE).Methods:A retrospective series of case studies. From January 2014 to October 2021, 31 patients (31 eyes) with ANPCE (ANPCE group) were diagnosed in the eye center of Beijing Tongren Eye Center of Beijing Tongren Hospital, Capital Medical University, and 17 patients (17 eyes) with ciliary body melanoma (control group) diagnosed at the same time were selected as the control group. There was no significant difference in age ( t=-0.564) and sex composition ratio ( χ 2=0.182) between the two groups ( P=0.576, 0.670). All patients underwent ultrasound biomicroscopy to obtain the measurement parameters: tumor height, maximum basal diameter, maximum diameter, ratio of maximum diameter to basal diameter and ratio of maximum diameter to height; tumor location, shape, internal echogenicity intensity, echogenicity uniformity, degree of sound attenuation, invasion of iris, anterior displacement of the iris, lens subluxation were observed. The measurement parameters and observation indexes of the two groups were compared by independent sample t-test and χ 2 test. Receiver operating characteristic (ROC) curve was drawn, area under the ROC curve (AUC) was determined, and parameter indicators with differential diagnosis value were screened. Results:The maximum diameter, height, maximum basal diameter, ratio of the maximum diameter to the maximum basal diameter, and the ratio of the maximum diameter to the height of the tumors in the ANPCE group and the control group were 5.64±0.98 mm, 4.24±0.59 mm, 3.66±0.71 mm, 1.58±0.34, 1.34±0.19 and 7.82±2.03 mm, 4.47±2.44 mm, 7.02±1.96 mm, 1.13±0.16, 2.09±1.06. The maximum diameter, the maximum basal diameter, and the ratio of the maximum diameter to the height of the tumor in the ANPCE group were all smaller than those of the control group, and the ratio of the maximum diameter to the maximum basal diameter was greater than that of the control group, and the differences were statistically significant ( t=-4.159,-6.808, -2.924, 6.257; P<0.05). The tumors in the ANPCE group were mainly spherical (87.1%, 27/31), with no significant acoustic attenuation (77.4%, 24/31), less invading the root iris (77.4%, 24/31), and the tumors were mostly located in the ciliary body coronal (74.2%, 23/31); tumors in the control group were mainly hemispherical (47.1%, 8/17) or spherical (47.1%, 8/17), with significant sound attenuation (76.5%, 13/17), most of the tumors invaded the iris (70.6%, 12/17), and the tumors were mostly located from the pars plana to the coronal (76.5%, 13/17). There were statistically significant differences in the position, shape, sound attenuation degree, and whether it invaded the iris between the two groups of eyes ( χ 2=15.132, 19.767, 13.118, 10.581; P<0.05). The results of ROC curve analysis showed that the ratio of the largest diameter to the largest base diameter, the degree of sound attenuation and the AUC of whether the iris was violated were higher, which were 0.881, 0.769, and 0.740, respectively. Conclusions:Ultrasound biomicroscopy is helpful in the diagnosis and differential diagnosis of ANPCE and ciliary body melanoma. The ratio of maximum diameter to maximum basal diameter, the degree of sound attenuation and whether it invades the root iris are important parameters to distinguish the two tumors.
