Abstract We present here the three-dimensional (3D) visualization fused with ultrasound and to evaluate its clinical application effect preliminarily. One hundred and eighteen patients with renal calculi in our hospital from September 2017 to December 2019 were prospectively randomized into two groups. The experimental group was treated with percutaneous renal puncture guided by the 3D visualization fused with ultrasound. The control group was treated with percutaneous renal puncture guided by B-ultrasonography (B-US). The puncture time, operation time, and the loss of hemoglobin in the experimental group were lower than those in the control group, and the success rate of establishing the channel at one time, and the coincidence rate between the channel and the longitudinal axis of the target renal calyx were higher. The stone clearance rate in the experimental group was higher, while the postoperative blood transfusion rate and interventional embolization rate in the experimental group were significantly lower. The difference was statistically significant (P < 0.05). 3D visualization assisted ultrasound could preliminarily guide precise navigation to puncture tissues, reduced operation time and bleeding, improved stone clearance rate and operation safety.

Abstract Calcitonin gene-related peptide (CGRP) has been confirmed with induction osteoblastic differentiation, but if it can make the three-dimensional culture of adipose-derived stem cells (ADSCs) to the osteoblastic differentiation, thus constructing tissue-engineered bone rare reports. To investigate the feasibility of exogenous CGRP-induced calcium alginate gel combined with ADSCs from rabbits in three-dimensional condition to construct tissue-engineered bone. ADSCs were obtained by collagenase I digestion of the subcutaneous adipose tissue of inguinal region of New Zealand rabbits. At the third passage, cells were mixed with sodium alginate to prepare calcium alginate gel, and the cells were assigned into two-group cultivates in 24 orifice plates. ADSCs in the control group were treated with DMEM/F-12 medium supplemented with 10−2 mol/L β-glycerophosphate sodium, 10−7mol/L dexamethasone, 50 mg/L ascorbic acid, 0.1 % volume fraction of fetal bovine serum. ADSCs in the experimental group were incubated with the same medium as above, and in addition 1.5 µg/L CGRP was added. The cells proliferation and the mRNA expressions of collagen I and osteocalcin were detected by MTT and RT-PCR assays, respectively and alkaline phosphatase(ALP)and calcium concentration at different induction time were detected. The cell proliferation curves were S shaped. The OD values of experimental group were higher than those of control group at 1, 3, 5, 7, 14, and 21 days after osteogenic induction (P < 0.05). ALP and alizarin red stains of ADSCs were all positive, but golden round nodes became bigger and more in the experimental group compared with the control group after 2 weeks. At 7 and 14 days, collagen I and osteocalcin mRNA expression were greater in the experimental group than the control group. ALP and calcium concentration of experimental group were higher than that of control group at 1, 2, 3, 4 weeks after osteogenic induction (P < 0.05). Thus, these results show that the CGRP-induced ADSCs combined with calcium alginate gel to osteoblasts differentiation.

Background: Three-dimensional printer technology can produce the personalized orthosis in various forms. Objective: To develop a personalized wrist orthosis using a three-dimensional scanner and three-dimensional printer for patients with wrist pain. Study design: A preliminary, prospective, randomized, open-label study. Methods: A total of 22 patients with wrist pain were randomly assigned to the control and experimental groups. The control group wore a cock-up orthosis and the experimental group wore a three-dimensional-printed wrist orthosis for 1 week. The Patient-Rated Wrist Evaluation, Jebsen Hand Function Test, and Orthotics and Prosthetics Users’ Survey were checked before and 1 week after the application. Results: The Patient-Rated Wrist Evaluation showed significant pain relief in both groups. Two items of the 28 Orthotics and Prosthetics Users’ Survey questions, “Put toothpaste on brush and brush teeth” and “Dial a touch tone phone,” showed high satisfaction scores, with statistically significant difference in the experimental group ( p = 0.036 and 0.004). Conclusion: The three-dimensional-printed wrist orthosis was superior to the cock-up orthosis for two items of the Orthotics and Prosthetics Users’ Survey. Wrist pain was reduced in the group wearing the three-dimensional-printed wrist orthosis as well as the group wearing the cock-up orthosis, so the three-dimensional-printed wrist orthosis could possibly play the same role as the cock-up orthosis. Clinical relevance A three-dimensional-printed wrist orthosis can be a substitute for a conventional ready-made wrist orthosis for patients with wrist pain with more satisfaction.

Abstract Background: Torsional malalignment has been considered as a risk factor for patella dislocation. But the influence of patella dislocation for torsional alignment development remains unknown. The present study aims to investigate whether the torsion alteration of the hindlimb occur after patella dislocation in growing rabbits. Methods: In the present study, 30 one-month old rabbits were included. The experimental group consists of 30 left knees of rabbits and were underwent patella lateral dislocation. And the control group consists of 30 right knees and no surgical procedure was performed. A CT scan was performed on each knee when the surgery was finished and at the time the rabbits were skeletal mature (5 months post-surgery). The angles of femoral version and tibial torsion were measured using a three-dimensional method and analyzed between the experimental group and control group. Results: The femoral version and tibia torsion in the experimental and control group immediately after surgery were not different significantly. However, 5 months after surgery, the femoral version angle of the experimental group (-5.50±6.13°) was significantly different with that of the experimental group (-10.90±4.74°)(P < 0.05). But the tibia torsion angle in the experimental group (7.17±7.25°) and control group (4.47±6.34°) were not significantly different (P = 0.144). Conclusion: From this study, patella dislocation can lead to alteration of femoral version in growing rabbits. This may indicate the early treatment for patella dislocation in children is particularly important to avoid torsional malalignment in the future. These findings may develop pathology and etiology of patella dislocation.

Objective: In this paper, a lattice algorithm is used to explore the effect of MRI on anesthesia when used in neurosurgery. Methods: Sixty patients with glioma were randomly divided into two groups. Thirty patients underwent intracranial glioma resection (iMRI group) under the guidance of intraoperative magnetic resonance imaging (iMRI) and functional neuronavigational, and 30 patients underwent functional neuronavigational. Guide the traditional resection of traditional craniotomy gliomas (group N), and record the general situation, anesthesia time, operation preparation time, operation time, intraoperative blood loss, infusion volume, blood transfusion rate, preoperative and postoperative hemoglobin concentrations, Postoperative body temperature, dosage of muscle relaxant, perioperative accidents related to iMRI and anesthesia. Results: Compared with the N group, the general conditions, anesthesia time, intraoperative blood loss, infusion volume, blood transfusion rate, hemoglobin concentration, and postoperative body temperature of the patients in the iMRI group were not significantly different (P > 0.05), but the time for preparation and operation. It was significantly prolonged, and the amount of muscle relaxant was significantly increased (P < 0.05). There were no accidents related to iMRI and anesthesia in both groups. Conclusion: The use of iMRI in neurosurgical surgery improves the accuracy of surgery and makes tumor resection more complete, but the operation time is significantly longer, and other perioperative characteristics are not different from traditional neurosurgery. iMRI is used for anesthesia in neurosurgery. In addition to following the general principles of neurosurgery anesthesia, attention should also be paid to the regulation of anesthesia for long-term surgery.

Abstract Objective This study aimed to evaluate the clinical outcomes for patients with stage IB2/IIA2 cervical squamous cell carcinoma treated with neoadjuvant chemotherapy combined with radical surgery. Methods A total of 68 patients with cervical squamous cell carcinoma were randomly divided into the experimental group (n = 35) and the control group (n = 33). The patients in the experimental group received paclitaxel plus cisplatin neoadjuvant chemotherapy for two cycles, then underwent radical hysterectomy and bilateral adnexectomy at 2 weeks post-chemotherapy. The control group only underwent radical hysterectomy and bilateral adnexectomy after the diagnosis of cervical squamous cell carcinoma. The toxic and side effects of chemotherapy in the experimental group were observed. Also, the operation method, operation time, blood loss, grade of wound healing, complications, and postoperative pathology were noted in the two groups. Primary foci and pelvic lymph node recurrence and distant metastasis were observed, and 3-year and 5-year survival rates were calculated. Results Only one patient in the experiment had grade III bone marrow suppression; no other grade III and IV chemotherapy toxic reactions were observed. The operation was successfully completed in all patients. The operation time, intraoperative blood loss, placement of the ureteral catheter, bladder injury, ureteric injury, postoperative urinary tub, pelvic drainage tube indwelling time, anal exhaust time, postoperative complications, and metastatic ratio of lymph nodes were not significantly different between the two groups (P > 0.05). The number of dissected lymph nodes, deep myometrial invasion, and vascular tumor emboli showed a significant difference in the experimental group compared with the control group (P < 0.05). The 3-year disease-free survival (82.9% vs 81.9%), 5-year disease-free survival (71.4% vs 60.6%), 3-year overall survival (91.4% vs 87.8%), and 5-year overall survival (82.9% vs 75.6%) were not statistically significantly different between the experimental group and the control group (P > 0.05). Conclusions Neoadjuvant chemotherapy in IB2/IIA2 stage cervical squamous cell carcinoma showed low toxic side effects. Radical surgery after chemotherapy is safe and feasible. It plays a coordinating role in reducing the tumor infiltration depth of the deep muscle layer and the incidence of vascular tumor emboli, reducing the use of postoperative adjuvant therapy, and improving the quality of life of patients, but does not improve the 3-year/5-year survival rate.
