The control network is an important developmental orientation in the remote control system. As the control network and information network are comparatively alike in the framework and technology, we can build a control network which is similar to the common information network. In the era when the information network is becoming increasingly mature, it is a royal road to construct or rebuild a control information network in the development of the control network by relying on the achievements made in the information network or current information resources. This paper expounds the construction idea of the control information network, gives the idiographic realization method and then researches into the real-time problem encountered in the control information network, and presents a three-closed-loop control system based on virtualized reality. The feasibility of the idea is validated via experiments and simulations separately.

Objective To evaluate the efficacy of radiofrequency thermocoagulation guided by three-dimensional computer tomography(3-D CT)for the treatment of severe recurrent glossopharyngeal neuralgia(GPN). Methods Twenty-nine patients of both sexes with recurrent intractable GPN, aged 42-75 yr, with recurrent course of 1-8 yr, of Barrow Neurological Institute(BNI)Pain Scale(BNI-P) class Ⅳ or Ⅴ, were enrolled in this study. Percutaneous radiofrequency thermocoagulation was applied to the middle and lower segment of the styloid process of the glossopharyngeal nerve under 3D CT guidance. Before operation and at 72 h, 6 months and 1 year after operation, BNI-P class and BNI Numbness Scale scores were recorded, and effective treatment and operation-related complications were also recorded. Re-sults Nineteen patients underwent one operation, 8 patients underwent two operations, and 2 patients un-derwent three operations. BNI-P class was significantly lower at each time point after operation than before operation(P<0.05). The rate of effective treatment was 100% at 72 h and 6 months after operation and 97% at 1 yr after operation. Different degrees of dysesthesias at the posterior part of the tongue on the affect-ed side occurred after operation and disappeared at 1 yr after operation. Operation-related nausea and vomi-ting, facial nerve damage, accessory nerve damage and fatality were not observed. Conclusion 3D CT-guided radiofrequency thermocoagulation of the glossopharyngeal nerve provides reliable efficacy and higher safety for the patients with severe recurrent GPN.

BACKGROUND:As tissue engineering brings new hope to the worldwide problem of articular cartilage repair,the construction of light-curing 3D printed hydrogel scaffolds with biomimetic composition is of great significance for cartilage tissue engineering. OBJECTIVE:To construct a biomimetic methacryloylated hyaluronic acid/acellular Wharton's jelly composite hydrogel scaffold by digital light processing 3D printing technology,and to evaluate its biocompatibility. METHODS:Wharton's jelly was isolated and extracted from human umbilical cord,then decellulated,freeze-dried,ground into powder,and dissolved in PBS to prepare 50 g/L acellular Wharton's jelly solution.Methylallylated hyaluronic acid was prepared,lyophilized and dissolved in PBS to prepare 50 g/L methylallylated hyaluronic acid solution.Acellular Wharton's jelly solution was mixed with methacrylyacylated hyaluronic acid solution at a volume ratio of 1:1,and was used as bio-ink after adding photoinitiator.Methylacrylylated hyaluronic acid hydrogel scaffolds(labeled as HAMA hydrogel scaffolds)and methylacrylylated hyaluronic acid/acellular Wharton's jelly gel scaffolds(labeled as HAMA/WJ hydrogel scaffolds)were prepared by digital light processing 3D printing technology,and the microstructure,swelling performance,biocompatibility,and cartilage differentiation performance of the scaffolds were characterized. RESULTS AND CONCLUSION:(1)Under scanning electron microscope,the two groups of scaffolds showed a three-dimensional network structure,and the fiber connection of HAMA/WJ hydrogel scaffold was more uniform.Both groups achieved swelling equilibrium within 10 hours,and the equilibrium swelling ratio of HAMA/WJ hydrogel scaffold was lower than that of HAMA hydrogel scaffold(P＜0.05).(2)CCK-8 assay showed that HAMA/WJ hydrogel scaffold could promote the proliferation of bone marrow mesenchymal stem cells compared with HAMA hydrogel scaffold.Dead/live staining showed that bone marrow mesenchymal stem cells grew well on the two groups of scaffolds,and the cells on the HAMA/WJ hydrogel scaffolds were evenly distributed and more cells were found.Phalloidine staining showed better adhesion and spread of bone marrow mesenchymal stem cells in HAMA/WJ hydrogel scaffold than in HAMA.(3)Bone marrow mesenchymal stem cells were inoculated into the two groups for chondrogenic induction culture.The results of qRT-PCR showed that the mRNA expressions of agglutinoglycan,SOX9 and type Ⅱ collagen in the HAMA/WJ hydrogel scaffold group were higher than those in the HAMA hydrogel scaffold group(P＜0.05,P＜0.01).(4)These findings indicate that the digital light processing 3D bioprinting HAMA/WJ hydrogel scaffold can promote the proliferation,adhesion,and chondrogenic differentiation of bone marrow mesenchymal stem cells.
