Studies of pickled vegetables and cause of esophageal cancer in Linxian. II. Determination of nitrosamines and their precursors]

Pickled vegetables are daily food consumed in the high-risk areas for esophageal cancer in China. We analyzed the nitrosamine content of Linxian pickles by GC/TEA and found that trace amounts of six nitrosamines (NDMA, NDEA, NMBA, NMAMBA, NDPA, NPYR) were present, with the highest concentrations being NDMA and NDEA (1.7 and 1.9 micrograms/kg wet weight respectively). The average level of nitrosamine precursors, such as nitrate (111.22 mg/L), nitrite (0.152 mg/L) and secondary amines (4.223 mg/L), in pickled vegetables were determined, and their pH values ranged from 3 to 5.

Nonspecific mitochondrial disease with epilepsy in children: diagnostic approaches and epileptic phenotypes

OBJECTIVES: This study sought to characterize epileptic phenotypes in children with nonspecific mitochondrial disease (MD) and to evaluate MD diagnostic approaches. METHODS: A retrospective analysis of the medical, electroencephalogram, and laboratory records of 142 patients with epilepsy was performed. The patients were evaluated for MD, and 124 patients were included in the final cohort. The MD criteria used included an oral glucose lactate stimulation test (OGLST) and urine organic acid/plasma amino acid (UOA/PAA) assays as metabolic indicators of modified Walker criteria, as suggested by Bernier et al. (Neurology 59:1406-1411, 2002). RESULTS: Twenty-two patients were classified as having definite MD (9), probable MD (5), possible MD (6), or pyruvate dehydrogenase (PDH) deficiency (3), including one patient which showed a respiratory chain (RC) defect and PDH deficiency. Seven out of eight patients in whom significant RC defects were observed showed complex I defects. In 14 patients, epileptic seizures start at infantile ages. Of 17 patients who substantially presented generalized seizures, 4 patients started with partial seizures. Five patients consistently presented only partial seizures. The OGLST and UOA/PAA assays were useful for a more precise diagnosis of MD, although low positive predictive value of the OGLST was regrettable. No patient was classified as definite MD by Walker's original criteria, but the use of our revised MD criteria resulted in the classification of nine additional patients as definite MD. CONCLUSIONS: MD manifested considerable diverse epileptic phenotypes and should be considered in the differential diagnosis of epilepsy in children with unexplained encephalomyopathy and progressive and fluctuating clinical courses.     

宫腔镜在辅助生殖技术中的应用

目的：探讨宫腔镜检查术在辅助生殖技术中应用的重要性。方法：对150例拟行辅助生殖技术的不育妇女行常规宫腔镜检查。结果：宫腔镜150例中47例（31％）有镜下异常，其中：子宫内膜息肉或息肉样增生18例（12％），子宫内膜单纯性增生17例（11％），子宫畸形7例（5％），宫腔粘连狭窄3例（2％），子宫内膜结核1例（0．7％），子宫黏膜下肌瘤或腺肌瘤1例（0．7％）。以宫腔镜诊断为标准，阴道超声诊断敏感性、特异性、阳性预测值、阴性预测值、准确率分别为66％（31／47）、98％（101／103）、94％（31／33）、86％（101／117）、88％（132／150），子宫造影分别为26％（12／47）、100％（95／95）、100％（12／12）、73％（95／130）、75％（107／142）。结论：宫腔镜检查术具有良好的可接受性和准确性，应作为辅助生殖技术前的常规检查。

Analysis of the Surface Ozone During Summer and Autumn at a Coastal Site in East China

The levels and temporal variations of surface ozone at a coastal site in East China during summer and autumn were analyzed and the influences of meteorological parameters on ozone were investigated. An inland city was chosen as a comparison site. The main results and conclusions of this study are: (1) ozone pollution, with a maximum 1 h concentration of 150.98 ppbv, was severe during summer and autumn at the coastal site; (2) the ozone level was obviously higher at the coastal site than that at the inland site in September; (3) besides temperature and solar radiation, sea-land breeze circulation is an important factor influencing the ozone level at the coastal site, and sea breeze often induce high ozone levels (the average ozone concentration for sea breeze was about 13 ppbv higher than that for land breeze).     

CT在外伤性胃肠道穿孔急诊中的价值

目的:探讨急诊外伤性胃肠穿孔的CT征象及诊断价值。方法:收集18例经手术证实的外伤性胃肠道穿孔的临床资料及CT征象,分析与总结胃肠道破裂穿孔CT扫描的各种有价值的表现。结果:18例外伤急诊患者中,胃、十二指肠、空回肠与结肠穿孔各1,2,12,3例,其中空回肠为多处破裂,CT主要征象为腹腔散在积液征、游离气腹征、肠系膜与肠壁增厚模糊征、造影剂外溢征。结论:CT扫描在外伤性胃肠道穿孔急诊患者的检查中有定性诊断价值,综合分析各种征象,会明显提高CT的诊断正确率。     

Two-stage treatment of skeletal Class III malocclusion during the early permanent dentition.

A patient with skeletal Class III malocclusion was treated in 2 phases during the early permanent dentition. In phase 1, maxillary protraction was combined with rapid palatal expansion; in phase 2, fixed appliances were placed. The results were good posttreatment, and, 1 year later, a favorable growth tendency could be observed. This report shows that treatment for a patient with skeletal Class III malocclusion can be started in the early permanent dentition, with very good final results.
