A SIX-CENTRE INTERNATIONAL STUDY OF THE OUTCOME OF TREATMENT IN PATIENTS WITH CLEFTS OF THE LIP AND PALATE: THE RESULTS OF A CROSS-LINGUISTIC INVESTIGATION OF CLEFT PALATE SPEECH

During the period 1964–73, 286 patients were treated for mandibular fractures. 229 patients (80%) attended the follow-up examination. The length of observation was from 1 to 9 years. The treatment and the follow-up evaluations in the 229 patients are described. Early fracture treatment has been the objective, also in patients who have undergone severe cerebral traumas. Antibiotic prophylaxis was implemented in cases of compound fractures. Preservation of teeth and tooth buds in the line of fracture was attempted. Clinical infection occurred in 0.4% of the patients. At the follow-up examination 1 patient presented with a fracture displacement outside the condylar process. Neither malocclusion nor pseudarthrosis following fracture or after treatment were seen. Permanent sensory disturbances in the innervation area of the mental nerve following fracture occurred in 8%. Radiological examination of the teeth in the line of fracture revealed unnoticed apical bone lesions in 17% of 118 patients. In a further 23% there was a negative response to the vitality test. Follow-up control of mandibular fractures is advised at 12 to 18 months after treatment.     

胃癌组织中Ki-67、P53、EGFR的表达及其与TNM分期的相关性研究

【摘要】目的：探究分析胃癌组织中Ki-67、P53、EGFR的表达及其与TNM分期的相关性。方法：随机选取我院2014年1月～2016年1月收治的120例胃癌患者及其手术切除的病理标本,收集患者的临床治疗资料,同时电话随访相关病例。运用免疫组化MaxVisionTM2/HRP染色法对胃癌组织中Ki-67、P53、EGFR抗原相关基因蛋白产物进行检测,对其表达水平与临床TNM分期的相关性及其临床意义进行分析,最后统计分析所有结果。结果：胃癌中P53、Ki-67、EGFR蛋白阳性表达率分别为26.67%（32/120）、40.00%（48/120）、12.50%（15/120）;高分化腺癌、有局部淋巴结转移、TNMⅡ期+Ⅲ期+Ⅳ期患者的P53、Ki-67联合检测阳性表达率均显著高于中低分化腺癌、粘液腺癌及印戒细胞癌、无局部淋巴结转移、TNMⅠ期患者（P＜0.05）。结论：胃癌患者血清P53、Ki-67、EGFR水平表达与TNM分期具有密切关系,三者联合检测在患者预后判断及评估中具有显著的指导价值,为临床上分子靶向治疗的研究提供了借鉴依据。     

Occult bone marrow involvement in patients with diffuse large B-cell lymphoma: results of a pilot study

AIMS: It is known that advanced stage disease in diffuse large B-cell lymphoma (DLBCL) confers a poor prognosis, and staging investigations are routinely performed at diagnosis, including a bone marrow (BM) biopsy. However, examination of the BM is usually limited to routine light microscopy, with the role of ancillary investigations remaining unestablished. The aim of this pilot study was to estimate the incidence of occult marrow involvement using flow cytometry, immunohistochemistry and immunoglobulin heavy chain (IgH) gene rearrangements, and to determine the impact on survival. METHODS: Clinical and pathological data were obtained on 36 patients diagnosed with DLBCL. Immunohistochemistry using CD3, CD45RO, CD20 and CD79a, and polymerase chain reaction (PCR) to look for IgH gene rearrangements were performed on formalin fixed BM trephines. RESULTS: Nine patients had morphologically apparent BM involvement. Occult marrow involvement was found in seven of 36 (19.4%) patients using the additional diagnostic modalities. When these cases were included with morphologically apparent cases in a proposed new definition of marrow involvement, the median survival of patients with BM involvement was statistically worse (p=0.02) than those without involvement. CONCLUSIONS: The results indicate that use of additional tests on BM at diagnosis can upstage disease for a proportion of patients, which appears to correlate adversely with survival.     

Determining a continuous marker for sleep depth

Detection and quantification of sleep arousals is an important issue, as the frequent arousals are known to reduce the quality of sleep and cause daytime sleepiness. In typical sleep staging, electroencephalograph (EEG) is the core signal and based on the visual inspection of the frequency content of EEG, non-rapid eye movement sleep is staged into four somewhat rough categories. In this study, we aimed at developing a continuous marker based on a more rigorous spectral analysis of EEG to measure or quantify the depth of sleep. In order to develop such a marker, we obtained the time-frequency map of two EEG channels around sleep arousals and identified the frequency bands that show the most change during arousals. We then evaluated classification performance of the potential signals for representing the depth of sleep, using receiver operating characteristic analysis. Our comparisons based on the area under the curve values revealed that the sum of absolute powers in alpha and beta bands is a good continuous marker to represent the depth of sleep. Higher values of this marker indicate low-quality sleep and vice versa. We believe that use of this marker will lead to a better quantification of sleep quality.     

肛周化脓性汗腺炎的核磁共振表现分析*

目的: 探讨磁共振成像(magnetic resonance imaging,MRI)对肛周化脓性汗腺炎( hidradenitis suppurativa,HS)诊断分期及治疗的临床应用价值。方法: 回顾性分析2018年1月至2020年12月就诊于包头医学院第二附属医院皮肤科及肛肠科的肛周HS患者的临床及MRI资料,结合临床Herley 分期,观察MRI显示的HS病灶分布与严重程度。结果: 10例患者中Herley Ⅰ期6例,Ⅱ期 4例,Ⅰ期患者MRI表现为局灶性炎症及脓肿,未见窦道。脓肿见于肛周(83 %),之后依次为臀区(50 %)、前会阴区(33 %)。Ⅱ期患者MRI表现为皮下组织炎症、脓肿及窦道,窦道未侵犯肌肉、肛管,未见窦道相互连接。4例患者中窦道见于肛周(100 %),前会阴区(25 %),臀区(25 %),坐骨直肠窝(25 %),臀沟(25 %)。脓肿见于肛周(100 %),前会阴区(50 %),臀区(50 %),坐骨直肠窝(25 %),臀沟(25 %)。本组患者MRI表现与临床分期一致。结论: MRI检查可明确肛周HS病变范围及深度,确定Herley 分期,为肛周HS的诊断、治疗及疗效判定提供客观的影像学依据。
