Purpose To detect the expressions of stress induced phosphoprotein 1 (STIP1) and estrogen receptor-α(ER-α) in papil-lary thyroid carcinoma and to analyse the relationship between STIP1 and ER-α. Methods 54 cases of paraffin-embedded tissues of papillary thyroid carcinoma, 18 cases of papillary thyroid carcinoma with lymph node metastasis, 15 cases of Hashimoto’ s thyroiditis, 10 cases of adjacent normal thyroid tissue were collected. The expressions of STIP1 and ER-αwere detected by immunohistochemistry, and the relationship between the expressions and clinicopathological features of papillary thyroid carcinoma was analyzed. Results The expression of STIP1 and ER-α in papillary thyroid cancer group ( 55. 6% and 44. 4%) were higher than that of normal thyroid group (10% and 0) and Hashimoto’s thyroiditis group (8. 3% and 0, all P<0. 05). STIP1 expressions was related to lymph node metastasis ( P<0. 05 ) , while ER-α expression was related to gender, TG-Ab and the merger of nodular goiter, but not related to lymph node metastasis (P>0. 05). The expressions of STIP1 and ER-α in papillary thyroid carcinoma were not related to patients’ age , tumor location, number of tumors, tumer size, invasion of capsule, the concomitant Hashimoto’ s thyroiditis and TPO-Ab ( all P>0. 05). And the expressions of STIP1 was not related to gender, TG-Ab and the merger of nodular goiter (all P>0. 05). A positive correlation was found between the expressions of STIP1 and ER-αin thyroid papillary carcinoma (P<0. 05). Conclusion STIP1 and ER-α in papillary thyroid carcinoma may be related with lymph node metastasis.

Objective To investigate the pathogenetic mechanism of ubiquitin-proteasome dysfunction in a model of Parkinson's disease(PD),which can provide the theoretical basis for PD.Methods After establishment of PD model induced by PSI in PC12 cells,proteins of untreated(DMSO) and PSI-treated PC12 cells were extracted 36 h after incubation,and then the maps of the extracted proteins were established by DIGE system.The altered protein spots were identified with MALDI-TOF Pro MS and database searching.Results Thirty-six treatment of PC12 cells with PSI induced the appearance of cytoplasmic Lewy body-like eosinophilic inclusions and apoptosis.The percentage of apoptotic cells was 25.53%.ERp29 were identified by MALDITOF Pro MS.The expression of ERp29 decreased in treatment group,compared with normal group(P

Positron emission tomography (PET) and PET/CT are playing increasingly important roles in the clinical evaluation and treatment of tumors. As neuroendocrine tissues, the hypothalamus and pituitary gland have their unique features, and PET can be valuable in evaluating hypothalamic-pituitary diseases lesions. This article reviews the application of PET in the clinical evaluation and treatment of hypothalamic-pituitary diseases.

8.Clinical features of endogenous bronchial foreign bodies and application of bronchoscopy in children.
Chinese Journal of Contemporary Pediatrics 2010;12(9):712-714
OBJECTIVETo study the clinical features of endogenous bronchial foreign bodies and the value of bronchoscopy in children.
METHODSOne hundred and six children who presented lobe or lung segment atelectasis by the chest X-ray and bronchial foreign body inhalation was excluded by bronchoscopy were enrolled. The original diseases included Mycoplasma pneumonia (n=62), endobronchial tuberculosis (n=24), bronchial pneumonia (n=16), nephrotic syndrome (n=2), laryngotracheal bronchitis (n=1) and bronchiolitis (n=1). On the basis of conventional treatment of the original diseases, bronchoscopy was performed in the children. Eighty children with bronchial foreign body inhalation severed as the control group.
RESULTSBronchoscopy showed the properties of endogenous foreign bodies: mucus emboli in 77 cases, cheese substances in 24 cases, dendritic white membrane in 4 cases, thrombosis in 1 case, and flaky pseudomembrane in 1 case. Hyperplasia of granulation tissue was seen in 25 cases. Of the 25 cases, endobronchial tuberculosis as the original disease was found in 22 cases. Mediastinal emphysema and pneumothorax occurred in 4 cases in the control group, but none in the endogenous foreign bodies group. The number of bronchoalveolar lavage by bronchoscopy in the endogenous foreign bodies group was significantly higher than that in the control group.
CONCLUSIONSBronchoscopy is valuable in the diagnosis and treatment of endogenous bronchial foreign bodies.

Objective To summarize the clinical characteristics,diagnosis and treatment of pulmonary sequestration(PS) in children.Methods The clinical data of 19 children with PS confirmed by operation and(or) imaging examination from Mar.2003 to May.2008 were analyzed retrospectively.Thirteen cases were male,and 6 cases were female.One case was newborn infant.Seventeen cases received operation.Intralober type had a pulmonary lobectomy and extralobar type had a sequestrectomy.Chest X-ray and CT scan examinations were performed on the patients before operation.Results Seventeen cases got complete cure by operation,and the mean age at operation was 5.2 years.Chest enhanced CT indicated abnormal feeding arteries.Lobectomy was performed in 13 cases of intralobar PS,4 cases of extralobar PS were resected in the separated lung tissue,and all patients had unilateral lesions.No late deaths occurred in this group except 1 case who was complicated with malformation,and the postoperative follow-up showed an excellent recovery.Conclusions The main diagnostic methods of PS are CT and angiography.The diagnosis of PS can be confirmed when systemic feeding arteries are indicated on enhanced CT scans.Surgical resection is the main choice of treatment in all cases of PS in order to prevent recurrent infection and hemoptysis.The excellent results can be obtained by surgery.

Background Hyaluronic acid is a mucopolysaccharide existing in extracellular matrix and having good biocompatibility.Using chemical crosslinking method can improve the physical properties of the material,so cross-linked hyaluronic has potential clinical application value.Objective The present study was to evaluate the histocompatibility and biological security of cross-linked hyaluronic acid as ophthalmic implant material.Methods Cross-linked hyaluronic acid implant material was prepared according to the criteria of Biological Evaluation of Medical Devices (GB/T16886.5-2003).Eighteen 8-week-old male New Zealand white rabbits were randomized into the experimental group and the control group.Cross-linked hyaluronic acid material with 5.0 mm diameter was implanted into corneal stroma interlaminationally in the experimental group,and only corneal stromal interlaminational pocket was made without any implanting material in the control group.Biological response of cornea was assessed in vivo from 1 week through 3 months after operation by slit lamp microscope.The corneas were obtained 2 weeks,1 month and 3 months respectively for histopathological examination.Mouse embryonic fibroblasts were cultured in cross-linked hyaluronic acid film plate,medical silicone material culture plate and regular culture plate respectively for 24 hours,and the cell growth state and morphology were observed under the inverted microscope and scan electron microscope.MTT assay was used to test the relative growth rate of the cultured cells 48 hours after cultured using extracted liquid of hyaluronic acid implant material.Results Cross-linked hyaluronic acid implant material showed a well healing to the corneas of rabbits during the observation duration,without obvious inflammatory response and neovascularization.The arrangement of stromal fibers was uniform in order,and no infiltration of inflammatory cells was seen under the light microscope.The cells grew well after cultured with cross-linked hyaluronic acid film and regular medium for 24 hours,but in the silicone culture group,fewer of adherent cells and more floating cells were found.The relative growth rate of the cells was 87.50% 48 hours after cultured with extracted liquid of hyaluronic acid implant material.Conclusions The cross-linked hyaluronic acid material has good histocompatibility and biological security in rabbit cornea tissue.
