Langerhans cell histiocytosis is an uncommon disease, involvement of the thyroid by langerhans cell histiocytosis is rare. Two cases of Langerhans cell histiocytosis of the thyroid confirmed by pathology were reported in this paper. The main clinical feature was enlargement of the thyroids. One patient had hypothyroidism. Meanwhile, the lungs and pituitaries of the two patients were affected. Langerhans cell histiocytosis of the thyroid had no typical symptoms and specific laboratory examination, and might be clinically diagnosed as chronic lymphocytic thyroiditis, benign or malignant thyroid tumors. Thyroid fine needle aspiration cytology might be useful in confirming the diagnosis. The effective treatments include systemic chemotherapy, local radiation therapy and surgical excision. The chemotherapy is still the major technological approach. Most patients can relieve partially after receiving the systemic chemotherapy.

Objective To establish a method of primary culture of human preadipocyte in a serum-free medium. Methods Collangenase digestion was used to dispart preadipocyte.The cells were identified by microscopy stained by oil red O and determination of the activity of Glycerol-3-phosphate dehydronase(G-3-PDH). Results The primary cultured human preadipocyte proliferated in the aserum-free medium successfully.In the differential serum-free medium the cells turned to be round on the 4 th day.The adipose drops began to cumulate in the cells,and to the most quantity until the 21 st day.Conclusion The human preadipocyte can be primarily cultured and induced to differentiate in serum-free medium,which is the base for researching the effects of hormones and factors to the proliferation and differentiation of preadipocyte.

AIM: To investigate the differentiation of human bone marrow mesenchymal stem cells (MSC) into chondrocytes in vitro and determine factors involving in the differentiation process. METHODS: MSC were separated from iliac bone marrow with lymphocyte separating medium using density centrifugation. Cells were cultured and expanded in medium until reaching required number. MSC was induced to differentiate into chondrocytes by adopting high cell density, supplying growth factor and using micromass culture. Cells were observed by HE staining. Matrix of cartilage was detected by alcian blue and toludine blue and cartilage specific collagen II was detected by immunohistochemistry. RESULTS: The structure of the micromass assumed that of cellular cartilage, alcian blue staining were uniformly positive and toludine blue detected diffuse metachromasia substance, cells uniformly expressed collagen Ⅱ. CONCLUSION: High cell density, growth factor and appropriate culture conditions are critical to induce differentiation of MSC into chondrocytes. [

OBJECTIVE:To consolidate the results of special antibacterial drug rectification so as to improve the rational medi-cation of antibacterial drugs. METHODS:By using the method of retrospective analysis,the antibacterial drug application data in 2011(before rectification and initial stage of rectification),2012(middle stage thereof)and 2013(later stage thereof)were sum-marized,compared and analyzed. RESULTS:After special rectification(Jan. 2011 vs. Dec. 2013),the utilization rate of antibacte-rial drugs in perioperative period for class I incision decreased from 80.42% to 24.49%. That of antibacterial drugs in emergency treatment decreased from 53.79% to 36.23%. The examination rate of microbial samples in inpatients who would use special-grade antibacterial drugs increased from 16.12% to 94.17%. The use intensity of antibacterial drugs by inpatients decreased from 70.28 DDDs/(100 persons·d) to 27.44 DDDs/(100 persons·d). The utilization rate of antibacterial drugs by inpatients decreased from 65.99% to 46.45%. CONCLUSIONS:Special rectification has remarkable effects on rational clinical application of antibacterial drugs. Regulation and evaluation should be strengthened to maintain the effects and continuously improvement should be made.

Objective To evaluate the diagnostic accuracy and integrity of two-dimension ultrasound (2DUS)assisted with spatio-temporal image correlation (STIC)for cardiac and vascular abnormalities in fetal heterotaxy syndrome (HS).Methods The retrospective study was conducted from Nov 2007 to Feb 2013.Forty-five fetuses with suspected heterotaxy syndrome on routine prenatal ultrasonic screening underwent STIC volume sweep.The diagnosis was confirmed by pathological or echocardiographic examination.STIC volume data sets of fetal hearts were off-line analyzed blindly by one doctor who had practiced fetal echocardiography for more than five years.The concordance and integrity levels of diagnosis with 2DUS or assisted with STIC were compared according with pathological results.Results There were 397 cardiac and vascular defects in 37 cases of right isomerism.The overall concordance of various defects in right isomerism diagnosed assisted with STIC (96.5%)was significantly higher than that of 2DUS (60.2%) (P <0.05).The concordance rates of right atria and ventricle isomerism,anomalies of ventriculo-arterial junction,arterial arch,systematic and pulmonary veins diagnosed assisted with STIC (78.9%,96.7%, 100%,100%,100%)were higher(P <0.05)than those of 2DUS (49.1 %,60%,34.7%,23.2%,62.2%). Percentages of diagnostic integrity levels (0 ~3)on 2DUS+STIC (8% on level 2,92% on level 3 )were significantly different(P <0.05)with those on 2DUS (1 1 % on level 0,21 % on level 1 ,57% on level 2, 1 1 % on level 3).There were 59 cardiac and vascular defects in 8 cases of left isomerism with the overall concordance of defects diagnosed assisted with STIC (89.8%)and 2DUS (81 .4%)being no difference (P >0.05).There was no significant difference in concordance rates of various defects of left isomerism diagnosed between two methods,except that the concordance rate of left atria isomerism diagnosed assisted with STIC was higher(P <0.05).There was no difference in percentages of diagnostic integrity levels (0-3)in left isomerism between two methods.Conclusions STIC technology may provide considerable diagnostic information for ultrasonic diagnosis of fetal heterotaxy syndrome,especially in abnormalities of atria and ventricle isomerism,ventriculo-arterial junction,arterial arches,systematic and pulmonary veins in right isomerism.

Objective To detect Ureaplasma urealyticum (Uu) and Mycoplasma hominis (Mh) in urogenital tract of healthy elementary and high school students,and to determine the biovars and serotypes of Uu isolates.Methods Urine specimens were collected from 957 healthy school children,including 404 elementary school students,260 junior high school students and 293 senior high school students,and submitted for Uu and Mh culture in selective liquid medium.Thc specimens positive for Uu and (or) Mh culture were subsequently subjected to PCR.The biovars and serotypes of Uu were determined.Results Uu was detected in 4.81％ (46/957) of the school children.Among the 46 Uu positive specimens,32 (69.57％) harbored Ureaplasma Parvum (biovar 1 ),14 (30.43％) Ureaplasma urealytieum (biovar 2); 12 (2.97％) were from elementary school students,including 9(75.00％) cases of Ureaplasma Parvum and 3(25.00％) Ureaplasma urealytieum,8(3.08％) were from junior high school students,including 5 cases of Ureaplasma Parvum and 3 Ureaplasma urealytieum,26 (8.87％) were from senior high school students,including 18 (69.23％) cases of Ureaplasma Parvum and 8 (30.77％)Ureaplasma urealytieum.Mh was positive in 9 (0.94％) school students,including 1 elementary school student,1 junior school student and 7 senior high school students.The detection rate of Uu was significantly higher in females than in males in all the 3 groups (elementary school,junior and senior high school) of students.Conclusions Mh and Uu are commensals in urogenital tract of elementary and high school students without symptoms.Ureaplasma Parvum is the predominant biovar in this population,though Ureaplasma urealytieum accounts for a significant proportion,which implies that Uu is commensal in healthy elementary and high school students,and females are more liable to be colonized than males.

Objective To investigate the levels of mieropartieles originated from platelet (PMP),endothelium (EMP),and tissue factor-bearing microparticles (TF+ MP) in diabetes mellitus and to analyze its relationship with diabetic angiopathy.Methods PMP,EMP or TF+ MP were measured in 106 cases of diabetes mellitus and 50 controls by flow eytometry.The differences of EMP between groups of diabetic macrovascular disease and diabetic microvascular disease were determined.Results The levels of EMP in diabetic patients were higher than that in the control(164.20±128.88 vs 63.81±40.84,P<0.05).Diabetic cases with complication showed higher expression level of EMP than those without complications(184.12±152.77,188.21±149.55 vs 138.53±99.87,both P<0.05).However,no distinct increase was observed in PMP and TF+ MP level in diabetes groups compared with control group.Conclusions Endothelial dysfunction,may contribute to the increased level of EMP in patients with diabetes,especially those complicated with vascular diseases.EMP level may be used to evaluate the status of endothelial function and the development of diabetic angiopathy.
