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 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.

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 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.

Aim To explore the antidepressant effect and the mechanism of self-made prescription of strengthening spleen and replenishing Qi ( SMP-SS-RQ) . Methods The depression model of chronic un-predictable mild stress ( CUMS ) was established in mice. The animals were randomly divided into control group, model group, SMP-SSRQ low, middle and high dose groups (8, 16, 32 mg·kg-1), with 12 mice for each group. The control group and the model group were given the same volume of saline, and other groups were given corresponding dose of SMP-SSRQ. Animals of each group were administered by gavage twice a day for two weeks. Behavioral indexes of mice were deter-mined by open field experiment, sugar consumption test, forced swimming test and tail suspension test. Quantitative real-time PCR (qPCR) and Western blot were respectively performed to detect mRNA and pro-tein expression levels of Igsf11 , Pdia2 and Sec14 l2 inprefrontal cortex and hippocampus. Results Com-pared with model group, depressed mice' s horizontal mobile score, upright number and the sugar water pref-erence index increased and FST as well as TST de-creased in all SMP-SSRQ groups(P<0.05). The de-pression symptoms in mice were obviously improved by SMP-SSRQ therapy. Low and high doses of SMP-SSRQ significantly reduced mRNA and protein expression lev-el of Igsf11 , Pdia2 and Sec14 l2 in the prefrontal cortex and hippocampus of the depressed mice, presenting significant statistical difference compared with model group ( P<0.05 ) . Conclusions SMP-SSRQ can ef-fectively improve mouse depressive behavior, and its mechanism may be related to the down-regulation of Igsf11 , Pdia2 and Sec14 l2 in mouse prefrontal cortex and hippocampus.

Thyroid-associated ophthalmopathy (TAO) belongs to autoimmun diseases, which is particularly closely related to the liver, spleen and kidney. Using these three organs as the theoretical foundation, the root of the disease can be grasped. Using syndrome differentiation, deficiency is the basic pattern and excess is the syndrome. The main reason for TAO is liver, spleen and kidney deficiency, while dampness, phlegm-blood stagnation in the eyes are pathogen. The rules of treatments are nourishing yin and clearing liver, supplementing and nourishing liver and kidney, removing dampness and phlegm, eliminating blood stasis and promoting circulation. By combining overall symptoms with ocular region changes, together with dynamic differentiation and flexible treatment, satisfactory results have been obtained in clinical practice.
