Journal of Peking University(Health Sciences) 2015;47(6):910-913
Objective:To study the metabolism of high density lipoprotein cholesterol ( HDL-C ) and apolipoprotein A-Ⅰ( ApoA-Ⅰ) in different thyroid function status during pregnancy. Methods:This study re-cruited thirty cases of euthyroid, with nineteen cases of subclinical hypothyroid and eight cases of subclini-cal hyperthyroid pregnancy. The concentrations of fasting serum HDL-C and ApoA-Ⅰwere detected and ana-lyzed from 9-12, 14-17, 23-26, and 37-40 gestational weeks. Friedman repeated measures ANOVA on ranks was adopted to analyze the changes of serum HDL-C and ApoA-Ⅰat different stages. General line-ar model ( GLM) was adopted to analyze the differences of serum HDL-C and ApoA-Ⅰin different thyroid function status during pregnancy. Results:There were no significant differences of maternal serum HDL-C among different stages (χ2 =5. 428,P=0. 143,χ2 =2. 027,P=0. 567,χ2 =2. 885,P=0. 410). There were significant differences of serum ApoA-Ⅰduring euthyroid and subclinical hypothyroid pregnancies (χ2 =46. 343, P<0. 001,χ2 =35. 984, P<0. 001), and no significant difference during subclinical hyperthy-roid pregnancy (χ2 =6. 750, P=0. 080). There were significant differences of serum HDL-C and ApoA-Ⅰbetween euthyroid and subclinical hyperthyroid pregnancies (P=0. 025,P=0. 027), and no significant differences between euthyroid and subclinical hypothyroid pregnancies (P=0. 378,P=0. 549). Conclu-sion:Subclinical hyperthyroidism affected the metabolism of maternal serum HDL-C and ApoA-Ⅰ, which could affect the fetal growth and development. Subclinical hypothyroidism ( after treatment with drugs) had no obvious effect on the metabolism of maternal serum HDL-C and ApoA-Ⅰ.

Journal of Experimental Hematology 2013;21(3):657-661
This study was purpose to investigate the diagnostic value of hematopoietic cell dysplasia in myelodysplastic syndrome (MDS). Sixty-four cases of WHO-MDS were detected by cytomorphology, cytohistochemical staining and bone marrow biopsy. The characteristics of hematopoietic cell dysplasia were analyzed, and its sensitivity and specificity were evaluated for WHO-MDS diagnosis. The results showed that though myeloblast, megakaryocytes presented in peripheral blood and granular Auer body, abnormal granular pseudo Pelger-Huër, vacuole of erythroid, micro-megakaryocytes appeared in bone marrow for diagnosis sensitivity were not very high, and respectively were 34.4%, 3.1%, 3.1%, 75.0%, 6.3%, 42.4%, the specificity of these characteristics was 100%. Moreover, erythroid odd nucleus, nuclear deformity, fragmentation, nuclear budding, ring sideroblasts, single and more round nuclear megakaryocyte had better reference value for WHO-MDS diagnosis. By bone marrow biopsy, the dysplasia and abnormal localization of immature precursor (ALIP) also were found in patients with WHO-MDS. More than half patients with WHO-MDS had mild to moderate increase in reticulin fibres. It is concluded that the cytomorphology assay is the base and key for the diagnosis of WHO-MDS. Diagnostic accuracy can be improved by combinative use of a variety of detection methods.

Objective To observe the effect of autophagy inhibitor on the activation of alcohol induced hepatic stel-late cells, and the mechanisms thereof. Methods HSC-T6 cells were cultured in vitro and divided into four groups, includ-ing blank control group, alcohol group, 5 mmol/L 3-MA+alcohol group (low alcohol group) and 10 mmol/L 3-MA+alcohol group (high alcohol group). RT-PCR was used to detect the expression levels ofα-smooth muscle actin (α-SMA) and typeⅠcollagen. The levels of LC3Ⅱ,α-SMA and typeⅠcollagen were detected by Western blot assay. The cell viability of HSC-T6 was detected by MTT assay. Results The mRNA expressions ofα-SMA, typeⅠcollagen and the protein of expressionsα-SMA, typeⅠcollagen and LC3Ⅱwere significantly up-regulated in alcohol group compared with those of control group (P<0.05), while the expressions of those parameters were significantly down-regulated in 10 mmol/L 3-MA+alcohol group (P<0.01). The mRNA and protein levels ofα-SMA and typeⅠcollagen were significantly decreased in two 3-MA-treated groups compared with those in alcohol group (P<0.05). Meanwhile, compared with the 5 mmol/L 3-MA+alcohol group,the protein expressions ofα-SMA, typeⅠcollagen and LC3Ⅱwere significantly decreased in10 mmol/L 3-MA+alcohol group (P < 0.05 ). Compared with the alcohol group,there was significantly lower proliferation activity in all two 3-MA-treated groups (P<0.05). Conclusion 3-MA can inhibit the protein expression of LC3Ⅱ,α-SMA and typeⅠcollagen induced by alcohol in HSC-T6 cells, and inhibit the proliferation of HSC cells.

Objective To analyze the ultrasonographic appearance of thyroglossal duct cysts and thyroglossal duct ifstula, and disicuss the value of ultrasonography in the diagnosis of thyroglossal duct cysts and thyroglossal duct ifstula. Methods Totally 142 cases of surgically and pathologically conifrmed thyroglossal duct cysts and thyroglossal duct ifstula cases in Beijing Children′s Hospital Afifliated to Capital Medical University from 2005 to 2012 were retrospectively reviewed and the ultrasonographic characteristics were analyzed. Results Among 142 cases, 128 cases of thyroglossal duct cyst were diagnosed by ultrasound. The ultrasonographic manifestation generally presented as anechoic and uneven medium echo cystic masses, with posteria wall echo enhancement. Most of the cyst walls were thin, and close to the thyoid, with or without deep ifstula. If the cysts were associated with infection, the wall would be thickening and echo enhancement of the surrounding soft tissue could be seen. Cysts ranged from the root of tongue to the suprasternal fossa, mostly in midline level of the neck. Of all the 128 cases, 95 cases were single cyst, round in shape; 33 cases had irregular shape with a fistula extended deeply, 13 cysts extended to the hyoid trailing edge, 20 cases extended to the mouth lfoor. Ultrasound examination revealed ifstulas in 10 cases, which presented as a hypoechoic thin strip-like echo inside the neck soft tissue, 6 cases extended to the hyoid bone direction, 2 cases extended to the mouthlfoor, 2 cases extended to the front thyroid. The other 4 cases showed anterior hypoechoic area, without cyst or ifstula structure. Conclusions Ultrasound is valuable in detcting the size, position, internal echo of the cyst and sinus, as well as showing their relationship with the hyoid. It is an optimal choice for the diagnosis of thyroglossal cyst and thyroglossal ifstula.
