Objectives The purpose of this study was to analyze the Chuna manual therapy usage status after the application of Chuna manual therapy health insurance. Methods This study analyzed the health insurance data (2019-2021). From April 2019 to December 2021, monthly data were collected by simple Chuna, complex Chuna (own expense 50%), complex Chuna (own expense 80%), and special (dislocation) Chuna. Results The major results are as follows. First, in hospital-level medical institutions, simple Chuna and complex Chuna (own expense 50%) occupied a similar proportion. In clinic-level medical institutions, simple Chuna occupies the largest proportion. Second, the amount of use decreased in all medical institutions after September, which is thought to be the result of restrictions on Chuna manual therapy health insurance. Conclusions Therefore, it is necessary to conduct research by receiving more detailed data onr Chuna manual therapy health insurance. Through this, an improved policy of Chuna manual therapy health insurance should be discussed.

Transanastomotic pancreatic duct stent placement during reconstruction following pancreaticoduodenectomy is widely performed to prevent postoperative pancreatic fistulas and duct stenosis. However, stent-related complications, such as stent occlusion and migration, may occur. Here, we report a rare case of a migrated pancreatic duct plastic stent. After pylorus-preserving pancreaticoduodenectomy, the stent migrated to the jejunum and served as a nidus of the stent-stone complex, which developed jejunal obstruction. The stent-stone complex was removed by explorative laparotomy.

Background: Red-skin root of Asian ginseng (Panax ginseng) significantly reduces the quality and limits the production of ginseng in China. The disease has long been thought to be a noninfectious physiological disease, except one report that proved it was an infectious disease. However, the causal agents have not been successfully determined. In the present study, we were to reveal the pathogens that cause red-skin disease. Methods: Ginseng roots with red-skin root symptoms were collected from commercial fields in Northeast China. Fungi were isolated from the lesion and identified based on morphological characters along with multilocus sequence analyses on internal transcription spacer, β-tubulin (tub2), histone H3 (his3), and translation elongation factor 1α (tef-1α). Pathogens were confirmed by inoculating the isolates in ginseng roots. Results: A total of 230 isolates were obtained from 209 disease samples. These isolates were classified into 12 species, including Dactylonectria sp., D. hordeicola, Fusarium acuminatum, F. avenaceum, F. solani, F. torulosum, Ilyonectria mors-panacis, I. robusta, Rhexocercosporidium panacis, and three novel species I. changbaiensis, I. communis, and I. qitaiheensis. Among them, I. communis, I. robusta, and F. solani had the highest isolation frequencies, being 36.1%, 20.9%, and 23.9%, respectively. All these species isolated were pathogenic to ginseng roots and caused red-skin root disease under appropriate condition. Conclusion: Fungal complex is the causal agent of red-skin root in P. ginseng.

A new medical materials scheduling system and its modeling method for the complex rescue are presented. Different from other similar system, first both the BeiDou Satellite Communication System (BSCS) and the Special Fiber-optic Communication Network (SFCN) are used to collect the rescue requirements and the location information of disaster areas. Then all these messages will be displayed in a special medical software terminal. After that the bipartite graph models are utilized to compute the optimal scheduling of medical materials. Finally, all these results will be transmitted back by the BSCS and the SFCN again to implement a fast guidance of medical rescue. The sole drug scheduling issue, the multiple drugs scheduling issue, and the backup-scheme selection issue are all utilized: the Kuhn-Munkres algorithm is used to realize the optimal matching of sole drug scheduling issue, the spectral clustering-based method is employed to calculate the optimal distribution of multiple drugs scheduling issue, and the similarity metric of neighboring matrix is utilized to realize the estimation of backup-scheme selection issue of medical materials. Many simulation analysis experiments and applications have proved the correctness of proposed technique and system.

The purpose of this article was to provide basic knowledge and treatment principles of patient with lymphedema, which was usually not treated at all, or the treatment given didn't work efficiently. Lmphedema is defined as an abnormal accumulation of protein-rich fluid, edema, and chronic inflammation within an extremity. Lmphedema may be classified as either primary results from defects with aplasia, hypoplasia, and hyperplasia in the lymphatic system at birth or secondary is caused by known precipitating factors such as cancer, infection, inflammation, radiation, surgery, or trauma etc. There are essentially several conservative treatment methods which has been utilized successfully to treat lymphedema in Samsung Medical Center. We used following procedures: CPT (Complex Physical therapy) or CDP (Complex Decongesitive Physical therapy) such as skin care, MLD (Manual Lymph Drainage), compression with short-stretch bandage, exercise, elevation, elastic stocking, and pneumatic compression. Our experiences shows that conservative treatments can significantly reduce lymphedema and prevent different complications.

The information technology intensive society rapidly moves from manufacturing industry to information technology industry. This paradigm of Robot is depending on intelligent Robot instead of labor. The conventional Robot worked through environmental variation and shift of job. This Robot is unactively response to men's mandate. And, this Robot have had iterative jobs through manipulation of men. But, this intelligent Robot have new technology through society paradigm shift. The outstanding feature of this Robot is perception function and cognition, mobility and manipulation. The definition of original Robot means forceful and tedious, slavery job. This is from robota, robotnick of the Czech Republic. Karel Capek, a playwriter of the Czech Republic use of this letter at 'Rossum's Universal Robots. The service of U-Health is the fusion of Information Technology and Medical Service. The U-Health provides for doing about household's medical behavior. Conclusionally, the Chungbuk has merit on establishment of national consilience complex such as Medical Robot and U-Health.

Complex diseases such as stroke and cancer have two or more genetic loci and are affected by environmental factors that contribute to the diseases. Due to the complex characteristics of these diseases, identifying candidate genes requires a system-level analysis of the following: gene ontology, pathway, and interactions. A database and user interface, termed StrokeBase, was developed; StrokeBase provides queries that search for pathways, candidate genes, candidate SNPs, and gene networks. The database was developed by using in silico data mining of HGNC, ENSEMBL, STRING, RefSeq, UCSC, GO, HPRD, KEGG, GAD, and OMIM. Forty candidate genes that are associated with cerebrovascular disease were selected by human experts and public databases. The networked cerebrovascular disease gene maps also were developed; these maps describe genegene interactions and biological pathways. We identified 1127 genes, related indirectly to cerebrovascular disease but directly to the etiology of cerebrovascular disease. We found that a protein-protein interaction (PPI) network that was associated with cerebrovascular disease follows the power-law degree distribution that is evident in other biological networks. Not only was in silico data mining utilized, but also 250K Affymetrix SNP chips were utilized in the 320 control/disease association study to generate associated markers that were pertinent to the cerebrovascular disease as a genome-wide search. The associated genes and the genes that were retrieved from the in silico data mining system were compared and analyzed. We developed a well-curated cerebrovascular disease-associated gene network and provided bioinformatic resources to cerebrovascular disease researchers. This cerebrovascular disease network can be used as a frame of systematic genomic research, applicable to other complex diseases. Therefore, the ongoing database efficiently supports medical and genetic research in order to overcome cerebrovascular disease.

Objectives: This study aimed to evaluate the ability of lithium disilicate ceramics to reproduce the A2 shade and to mask A4 substrates. Materials and Methods: Twenty-four discs (8 mm in diameter, shade A2) of high translucency (groups 1-3) and low translucency (groups 4-6) of IPS e.max ceramic with different thicknesses (0.5, 0.75, and 1 mm) were fabricated as monolithic structures. In addition, discs of medium opacity (group 7-8) with different core/veneer combinations (0.3 mm/0.7 mm and 0.5 mm/0.5 mm) were fabricated as bilayer structures. Specimens were superimposed on an A4 substrate (complex). The color changes of the complex were measured using a spectrophotometer on a black background, and the ΔE values of the complex were compared with either the A4 substrate or the A2 shade tab. One-way analysis of variance, the Tukey honest significant difference test, and the Fisher test were used to analyze the data (p < 0.05). Results: Significant between-group differences were found for comparisons to both the A4 substrate and the A2 shade (p < 0.05). When compared with the A4 substrate, the ΔE values in all groups were in the non-acceptable range. When compared with the A2 shade, the ΔE values in all groups, except groups 2 and 3, were in the clinically acceptable range. Conclusions: All translucencies and thicknesses masked the underlying dark substrate. However, the low-translucency IPS e.max Press better reproduced the A2 shade.

Ultrasound sonication along with microbubble (MB) could enhance drug delivery to promote the absorption of anticancer drugs into cancers in a noninvasive and targeted manners. In this study, we verify the acute drug delivery enhancement (within an hour) of two representative focused ultrasound driven drug delivery enhancement methods (MB and Doxorubicin-coated Nanoparticle complex (MB-NP) based). Experiments were conducted using in vivo mouse model with MDA-MB-231 breast cancer cell line. Ultrasound generated by single-element 1 MHz focused ultrasound transducer was delivered in pulsed sonication consisted of 0.125 msec bursts at a pulse repetition frequency of 2 Hz for 20 seconds without a significant increase in local temperature (less than $0.1^{\circ}C$) or hemorrhage. Doxorubicin concentrations in tumors were improved by 1.97 times in the case of MB-NP, and 1.98 times by using Doxorubicin and MB separately. These results indicate anticancer drug delivery based on MB and MB-NP can significantly improve the effect of anticancer drugs delivered to tumors in a short time period by using low-intensity focused ultrasound.
