Key symptoms selection for two major syndromes diagnosis of Chinese medicine in chronic hepatitis B / 中国结合医学杂志

<p><b>OBJECTIVE</b>To identify key symptoms of two major syndromes in chronic hepatitis B (CHB), which can be the clinical evidence for Chinese medicine (CM) doctors to make decisions.</p><p><b>METHODS</b>Standardization scales on diagnosis for CHB in CM were designed including physical symptoms, tongue and pulse appearance. The total of 695 CHB cases with dampness-heat (DH) syndrome or Pi (Spleen) deficiency (SD) syndrome were collected for feature selection and modeling, another 275 CHB patients were collected in different locations for validation. Key symptoms were selected based on modified information gain (IG), and 5 classifiers were applied to assist with models training and validation. Classification accuracy and area under receiver operating characteristic curves (AUC) were evaluated.</p><p><b>RESULTS</b>(1) Thirteen DH syndrome key symptoms and 13 SD syndrome key symptoms were selected from original 125 symptoms; (2) The key symptoms could achieve similar or better diagnostic accuracy than the original total symptoms; (3) In the validation phase, the key symptoms could identify syndromes effectively, especially in DH syndrome, which average prediction accuracy on 5 classifiers could achieve 0.864 with the average AUC 0.772.</p><p><b>CONCLUSION</b>The selected key symptoms could be simple DH and SD syndromes diagnostic elements applied in clinical directly.

Anesthetic management for a patient with severe mento-sternal contracture: difficult airway and scarce venous access: A case report / 대한마취과학회지

There are many problems in the anesthetic management of patients with scar contracture. In this case, a 41-year-old male with severe scar contracture on his face, neck, anterior chest, and both shoulders underwent surgery for resurfacing with flaps. We tried to awake fiberoptic orotracheal intubation with GlideScope(R) Video laryngoscope guide after surgical release of contracture under local anesthesia. We report a successful management of a patient with severe burn contracture achieved by combined effort of surgeons and anesthesiologists.

Non-surgical management of temporomandibular joint disorder using specially designed dry needle: A report of 3 cases

Pains derived from the temporomandibular joint are not treated easily. Recently, an arthroscopic surgical management has been reported, but its efficacy has not been proven yet. In this case report, we introduce an effective non-surgical treatment technique for the temporomandibular joint using a specially designed dry needle under ultrasonography guidance. Since the patient has pain related to mouth movement, accompanying decreased mouth opening, clicking sound or crepitus on physical examination, this approach will be helpful for pain relief and for functional recovery of the temporomandibular joint.

Influence on mechanical properties and microstructure of nano-zirconia toughened alumina ceramics with nano-zirconia content / 华西口腔医学杂志

<p><b>OBJECTIVE</b>To investigate the mechanical properties and microstructure of nano -zirconia toughened alumina ceramics with variety of nano-zirconia content in centrifugal infiltrate casting processing of dental all-ceramic.</p><p><b>METHODS</b>Composite powder with different ethanol-water ratio, obtained serosity from ball milling and centrifugal infiltrate cast processing of green, then sintered at 1 450 degrees C for 8 h. The physical and mechanical properties of the sintered sample after milling and polishing were tested. Microstructures of the surface and fracture of the sintered sample were investigated by SEM.</p><p><b>RESULTS</b>The experimental results showed that there had statistical significience (P < 0.01) on static three-point flexure strength and Vickers Hardness in three kinds of different nano-zirconia content sintered sample. Fracture toughness of 20% group was different from other two groups, while 10% group had not difference from 30% group (P < 0.05). The mechanical properties of this ceramic with 20% nano-zirconia was the best of the three, the static three-point flexure strength was (433 +/- 19) MPa and fracture toughness was (7.50 +/- 0.56) MPa x min 1/2. The intra/inter structure, fracture of intragranular and intergranular on the surface and fracture of sintered sample in microstrucre was also found.</p><p><b>CONCLUSION</b>Intra/inter structure has strengthen toughness in ceramics. It has better toughness with 20% nano-zirconia, is suitable dental all-ceramic restoratives.</p>
