Abstract: Objective To analyze a case of bloodstream infection caused by Ureaplasma urealyticum after abortion in Anxi County Hospital, so as to provide basis for the clinical diagnosis and treatment. Methods　The diagnosis of Ureaplasma urealyticum in this patient with bloodstream infection was retrospectively analyzed. The basic clinical data and laboratory diagnosis data were collected, including the characteristics of blood culture curve, Wright staining of culture medium, drug sensitivity of Mycoplasma liquid identification, colony characteristics of solid medium, and the conclusion of targeted DNA sequencing. Through the comprehensive analysis of the above data, the rapid diagnosis of this case can be realized by optimizing the detection and diagnosis process. Results　The clinical manifestations of this patient were fever of 38.5 ℃, CRP:14.85 mg/L, WBC:14.33×109/L, NET: 85.40%, PCT: 0.12 ng/mL, IL-6: 665.6 pg/mL, positive after 3 days of blood culture, no bacteria were found in Gram stain, and sand-like purple bacteria were observed after adding Wright's stain. After inoculation in blood agar, Mycoplasma solid and liquid medium, no colonies were grown in blood agar, after 48 h and 5 d. On Mycoplasma A7 agar, the edge of brown fried egg colony was striature, and it could be identified as Ureaplasma urealyticum with the Mycoplasma ID & AST panel, which was resistant to quinolones and spectinomycin, but sensitive to macrolides, tetracyclines and lincomycin. Subsequent targeted DNA sequencing results were also confirmed for Ureaplasma urealyticum. Before receiving the report, clinical experience treatment with ceftriaxone metronidazole was used to fight infection with negative bacilli and anaerobic bacteria. Mycoplasma was not treated with targeted treatment. After 3 days, the patient's body temperature returned to normal, inflammation index decreased, and the patient asked to be discharged. Conclusions　At present, there are few reports of bloodstream infection caused by Ureaplasma urealyticum, and the lack of clinical understanding can easily lead to misdiagnosis and missed diagnosis. In order to improve the detection rate of Mycoplasma in blood culture, it is necessary to optimize the detection procedure of blood culture and provide accurate diagnosis and treatment basis for clinical practice. However, it is clear from this case that Mycoplasma bloodstream infection cases are self-limited infection and can recover by themselves without targeted treatment in patients with normal immunity. Therefore, it is very important to protect the immunity of patients.

Objective To investigate the clinical and electroencephalogram (EEG) characteristics of children with electrical status cpilepticus during sleep (ESES), and the response to medication therapy. Methods AEEG and VEEG including an entire sleeping c-ycle were performed on 26 patients with ESES. The clinical and EEG changes, neuropsychological impairment and the response to medication therapy were followed up. Results Twenty five patients had seizures,21 cases had normal psychomotor development before ESES. After the onset of the disease,Fifteen cases developed language disorder, 16 cases developed psychological and behavior abnormalities, 13 cases had both of the problems Seventeen patients belonged to epileptic syndrome. Patients in this cohort had good response to clonazepam and valproate treatment. Cortical steroid could dispel the electrical discharge. Eighteen patients had been followed up. Seizures stopped in 15 cases after treatment ESES disappeared in 16 cases, 4 of them still had neuropsychological impairment ESES sustained in 2 cases Conclusions ESES is a specific EEG phenomenon. Continue epileptic form discharge during non - rapid cye movement sleep is the major cause of neuropsychological impairment in patients with ESES. To control the seizures and electrical state are very important for the prevention and treatment of neuropsychological impairment.

Objective To study the expression level of thyroid insulin-like growth factor-Ⅰ (IGF-Ⅰ) in iodine deficiency and excess mice and the effect of thyroid gland IGF-Ⅰ in the thyroid morphological change. Methods Forty-eight Balb/c mice were chosen as studied objects,weighing about 16 g. They were divided into three groups: low iodine(LI,iodine content of 50 μg/kg in feed,drinking deironized water) group,normoi(NI,iodine content of 300 μg/kg in feed,drinking deironized water) group and high(HI,iodine content of 300 μg/kg in feed,iodoine of content 14 700 μg/kg in drinking) group,16 mice in each group. Mice were put to death after 12 weeks and taken out of their thyroid gland. The body weight,absolute and relative weights of thyroid gland were measured and the morphological change of thyroid gland were observed under microscope. The expression levels of thyroid gland IGF-Ⅰ mRNA and protein were detected by RT-PCR and immunohistochemistry,respectively. Results There were statistical significances between groups of thyroid absolute and relative weights(F = 315.881,405.921,all P < 0.01). LI group [(10.71±4.03) mg,(44.98±15.39)mg/100 g body weight]and HI group [(3.42±1.17)mg,(13.50± 3.89)mg/100 g body weight]had heavier thyroid absolute and relative weights than NI group[(2.11±0.53)mg,(8.35±1.98)mg/100 g body weight,all P < 0.01]. Under microscopy,the thyroid follicle capacity grew down and the follicle quantity grew up in LI group,the epithelium was stylolitic,the colloid diminished or absence in follicular cavity,while HI group presented colloid accumulation without follicular hyperplasia. The expression level of thyroid gland IGF-Ⅰ mRNA in LI group(1.03±0.32) was more than that in NI(0.65±0.19) and HI(0.59± 0.20) groups(F= 7.518,P< 0.01). In contrast to NI,there was no difference in the expression level of thyroid gland IGF-Ⅰ mRNA in HI group(P > 0.05). The brownish particles of LI group were more than NI and HI groups in the thyroid follicle epithelium by immunohistochemistry,while HI group was less than NI group. Conclusions The mice of iodine deficiency presented follicular hyperplasia goiter,the mice of iodine excess presented colloid accumulative goiter. The change of IGF-Ⅰ mRNA and protein expression may participate morphologleal change,indicating autocrine IGF-Ⅰ of thyroid gland may play an important role in regulating goiter formation.

Objective Take alkaline ashing method as golden standard to explore the accuracy of chloric acid digestion method in determination of human milk iodine. Methods Sixty one breast milk samples collected in Hexi district of Tianjin was measured by the method for determination of iodine in foodstuff by As3+-Ce4+ catalytic spectrophotometry (referred to as the alkaline ashing method) published in 2008 and the method for determination of iodine in urine by As3+-Ce4+ catalytic spectrophotometry(referred to as acid digestion) published in 1999, respectively. were highly correlated(r = 0.960, t = 26.3, P < 0.01), and the regression equation was (Y) = - 28.1 + 0.808X, in which X was independent variable, that is the results of alkaline ashing method; (Y) was dependent variable, that is the estimated data of chloric acid digestion method. The average difference of the results measured by the two methods was 68.3 μg/L, and the results from chloric acid digestion was 38.9% which lower than that of alkaline samples were diluted by 3,4 and 5-fold and then digested by chloric acid, the liquid clarification rates were 80.3% ashing and chloric acid digestion method were, respectively, 165.4, 110.0 μg/L. Conclusions Compared with alkaline ashing method, the results determined by chloric acid digestion method are significantly lower. It is suggested that there are systemic errors in chloric acid digestion method, which means that alkaline ashing method can not be replaced by the chloric acid digestion method.

OBJECTIVETo investigate the role of fascin, an actin bundling protein, in the development and progression of human esophageal squamous cell carcinoma (ESCC), and explore its association with the clinicopathologic characteristics and 5-year survival of the patients.

METHODSUsing tissue array and immunohistochemistry, the expression of fascin was determined in 241 ESCC tissues and the corresponding normal esophageal mucosal tissues.

RESULTSESCC tissues showed a significantly higher overexpression rate of fascin than the corresponding normal esophageal mucosal tissues (68.9% vs 15.5%, P<0.05). The overexpression of fascin was correlated to lymph node metastasis and TMN stage, but not to the patients' age, gender, tumor differentiation and general classification. Survival analysis showed that abnormal expression of fascin was associated with the 5-year survival rate of patients with ESCC.

CONCLUSIONSThe abnormal expression of fascin may play an important role in the progression of ESCC, and detection of fascin expression may have important prognostic values.

OBJECTIVEX-linked adrenoleukodystrophy (ALD) is a genetically determined disorder that involves the nervous system white matter, axons, adrenal cortex and testes. The typical clinical manifestations are progressive psychomotor regression, vision and/or auditory impairment and adrenal insufficiency. The clinical manifestation, biochemical change and genetic counseling work of X-linked ALD were analyzed.

METHODSThe clinical features of 29 cases with ALD were summarized and analyzed, including symptoms and signs, measurement of blood very long chain fatty acids (VLCFA), adrenal function, cranial magnetic resonance imaging (MRI) and pedigree investigation.

RESULTSAmong these 29 cases, the clinical phenotype could be classified into childhood cerebral (22 cases), adolescent cerebral (4 cases), adrenomyeloneuropathic (1 case), Addison's disease (1 case) and asymptomatic or presymptomatic (1 case) types. Nine of them had positive family history. Pedigree investigation was consistent with typical sex-linked recessive inheritance. There were 45 ALD patients in these 29 pedigrees. The neurological manifestations varied among members of the same family. Nine cases died during follow up. The causes of death were central respiratory failure or other complications of ALD and so on. Laboratory tests demonstrated abnormally high plasma levels of VLCFA in ALD patients; MRI demonstrated symmetric butterfly-like low T(1) and high T(2) signals in the parieto-occipital white matter. The impairment in the splenium of corpus callosum made the bilateral lesion region converge into one. It could progress anteriorly and injure the bilateral posterior limb of internal capsule and the temporal lobe, and could injure the brainstem inferiorly. Following intravenous injection of contrast material, thin stripe of lacelike enhancement could be observed.

CONCLUSIONSThe atypical initial symptom of ALD was seizures. The MRI showed abnormal signal in the cerebellar white matter. This disease can influence the normal development of children, this was more pronounced in the childhood cerebral ALD type. It tended to progress rapidly with dementia, vegetative state or death. Since antenatal diagnostic method is available now, emphasis should be made on the antenatal examination in order to make an early diagnosis and abort pregnancy if necessary.
