Objective: The purpose is to explore the method and clinical effects of total nasal reconstruction with the assistance of three-dimensional (3D) scanning, 3D printing and monitoring the blood circulation after operation. Methods: 3D scanning: Artex Eva 3D scanner was used to record the nose data of 500 volunteers from Xuzhou Medical University and its affiliated hospital from September 2016 to February 2017. A nose database of normal individuals was established, of which male was 138 and female was 362. In addition, 3D facial scanning was performed in patients wish to total nasal reconstruction. 3D printing: The individualized nasal structure was designed, with the assistant of patients′facial characteristics, combined with the normal nose database and the opinion of the patients. Anactual nose model was used as guidance during the operation. Postoperative monitoring: The blood flow and the retraction rate of forehead flap after surgery were measured using Laser Doppler Flowmeter and Geomagic Qualify software. The blood flow values, the temperature and the surface area of the flap were recorded and analyzed. Results: The nasal database of normal people in the Huaihai region successfully established. Overall, the width of the nose takes up a quarter of the width of the faces, and the length is 1/3 of the distance from the hairline to the chin. From February 2017 to June 2018, 7 cases underwent total nasal reconstruction operations were performed by this procedure. The nasal models were all successfully printed out, as the guide of flap taken during the operation. The mean operation time of the cases was (2.45±0.75) h, and the follow-up time was 5-15 months, with an average of 12.5 months. After the operations, the retraction rate of the forehead flap were (21.8±2.72)% in one month, and (29.1±1.82)% in six months. All patients are satisfied with the nasal appearance. Conclusions Nasal reconstruction with forehead flap based on 3D scanning and 3D printing, provides objective targets for nasal fine-structure in a noninvasive way. The postoperative monitoring of the blood flow promotes the successful completion of the total nose reconstruction.

Objective To evaluate the application of Friedman family assessment model in home care patients with depression. Methods A total of 80 patients with depression were treated by their visit serial number, and the Single numbers were arranged into the intervention group, the even numbers were arranged into the control group, each of 40 cases. In the control group, patients were used conventional drug therapy and made an appointment in the outpatient. On this basis, patients in the intervention group were utilized the Friedman family assessment model as a guide for home care intervention. Before and after the intervention, patients were applied the Hamilton depression scale 17 ( HAMD 17) to evaluate the extent of the patients′depression. We used generic quality of life Inventory-74 ( GQOLI-74) assessed the depressed patients′ life quality. Results After 16 weeks the results showed the HAMD17 score of the intervention group point was (6. 82 ± 2. 49) lower than that of the control group (8. 26 ± 2. 01) (t = 2. 82,P < 0. 01). The total score of GQOLI-74 in the intervention group was (230. 00 ± 20. 65), and its three dimensional points were as follows:physical function (65. 73 ± 8. 26), psychological functioning (59. 87 ± 8. 92), social functioning (56. 13 ± 10. 26), which were significantly higher than that of the control group (213. 94 ± 19. 28) points, (60. 06 ± 9. 19) points, (53. 63 ± 8. 44) points, (49. 76 ± 9. 72 ), with the statistical difference (t = - 3. 65, - 2. 91,- 3. 22, - 2. 86, respectively;P < 0. 01). Conclusions Friedman family assessment model is a more effective rehabilitation methods, especially on reducing the extent of home care patients with depression, promoting the rehabilitation of the disease and improving the quality of life of patients.

Objective?To explore the effects of ideation and imitation behavior training on rehabilitation in patients with chronic schizophrenia. Methods?Totally 200 schizophrenia patients admitted and treated in 2016 from Fuzhou Neuro-Psychiatric Hospital were selected and equally randomized to treatment group (n=100) and control group (n=100) according to the random number table. Patients in the control group received conventional nursing, while patients in the treatment group received ideation and imitation behavior training for 8 weeks on this basis. Wisconsin Card Sorting Test (WCST), Nurses' Observation Scale for Inpatient Evaluation (NOISE) and Personal and Social Performance Scale (PSP) were used to compare the rehabilitation effects between the two groups. Results?After intervention for 8 weeks, the score for correct response in WCSI in patients in the treatment group was (24.78±7.39), higher than that of patients in the control group, and the score for continuous mistakes in WCSI in patients in the treatment group was (14.78±5.27), lower than that of patients in the control group (t=3.800, 3.640;P＜0.01). After intervention for 8 weeks, the scores for NOISE (200.06±26.09) and PSP (79.83±4.21) in patients in the treatment group were higher than those of patients in the control group (t=6.880, 19.040;P＜0.01). Conclusions?Ideation and imitation behavior training helps to improve the patients' cognitive performance, including attention, memory, linguistic competence and reasoning ability, as well as self-care ability of daily living and social function, and promotes chronic schizophrenia patients' rehabilitation.

Objective:To investigate the efficacy and safety of acute stent implantation during endovascular treatment for patients with emergent large vessel occlusion due to intracranial atherosclerotic stenosis.Methods:A retrospective analysis was carried out on 46 patients with emergent large vessel occlusion due to intracranial atherosclerotic stenosis who received endovascular treatment at the Strategic Support Force Medical Center from January 2015 to August 2022. Twenty-seven patients underwent balloon angioplasty alone and 19 patients underwent acute stent implantation. The baseline characteristics, modified thrombolysis in cerebral infarction (mTICI) score of the responsible vessels, modified Rankin scale (mRS) score 90 days after operation, incidence of symptomatic intracranial hemorrhage and mortality of the two groups were evaluated.Results:The proportion of effective recanalization of the offending vessels (mTICI≥2b) in the acute stenting group was slightly higher than that in the balloon angioplasty group (16/19 vs. 81.5%), but the difference was not statistically significant ( P>0.05). Besides, there was no significant difference in the median of mRS between the acute stenting group [3.0(0, 4.0)] and the balloon angioplasty group [4.0(1.0, 5.0)] 90 days after operation ( P>0.05). In terms of safety, the incidence of symptomatic intracranial hemorrhage and mortality were comparable between the two groups ( P>0.05). Conclusions:The effect of acute stent implantation during endovascular treatment for patients with emergent large vessel occlusion due to intracranial atherosclerotic stenosis is not inferior to that of balloon angioplasty, and it does not increase the risk of intracranial bleeding complications.

Objective:To evaluate the effects of adipose-derived stem cells (ADSCs) and ADM microparticle on diabetic wound healing.Methods:ADSCs was co-cultured with ADM microparticle in vitro. The models of diabetic nude mice were established by intraperitoneal injection of STZ and the full-thickness skin defects were designed on the back. All 24 diabetic mice were randomly divided into 4 group: experimental groups were transplanted with ADSCs and ADM microparticle and the other groups were transplanted with ADSCs, ADM microparticle and blank control group was set up. On the 7th and 14 th days, the wound healing rate of 3 mice randomly selected from each group was calculated, and the thickness between dermis and epidermis was measured by hematoxylin and eosin staining. The density of neovascularization was measured by immunohistochemical staining. The differences were compared between the groups.Results:Compared to the ADSCs groups, the mice of the experimental groups showed higher cell survival rate. The wound healing rate in the experimental groups was (86.0±2.7)% (7 days) and (98.5±1.1)% (14 days), thicker dermis-epidermis distance was (99.1±1.8) μm (7 days) and (124.3±4.3) μm (14 days) ( P<0.05), and higher density of neovascularization was noted. Conclusions:The transplantation with active ADM microparticle can significantly promote neovascularization and wound healing of diabetic wound.
