Objective To discuss the pathological morphological features of the macrofollicular variant of papillary thyroid carcinoma ( MFPTC ) .Methods Clinical data of 2 cases of MFPTC were reviewed .The his-topathological and immunohistochemical features were analyzed .Relevant literatures were reviewed .Results The histological characters of MFPTC mainly included its multiple macrofolliculus , plenty of colloid and atypical nuclear morphology.Immunohistochemistry stain showed cytokeratin-19, Galectin-3 and HBME-1 expressed simultaneously. Conclusions MFPTC is a thyroid papillary carcinoma with unique histological characters .It should be differen-tially diagnosed from some benign lesions such as nodular goiter and follicular adenoma .Immunohistochemical stain of cytokeratin-19, Galection-3 and HBME-1 may be very helpful in the diagnosis and differential diagnosis .

Objective To examine the expression of inhibitory chondroitin sulfate proteoglycans (CSPGs) and in-vestigate their potential effects on neural plasticity in the peri-infarct cortex and ipsilateral thalamus after focal cerebral infarction in hypertensive rats. Methods Twenty-four adult renovascular hypertensive Sprague-Dawley rats per group were subjected to permanent right middle cerebral artery occlusion(MCAO) or sham operation. Twelve rats which were se-lected randomly from per group at each time point were decapitated and their brains were removed and cut into coronal sections at 7 and 14 days post MCAO. The expression of CSPGs, NG2 and Neurocan was examined using immunostaining and western blot. Results All rats displayed neurological deficits to varying degrees and the expression of CSPGs, NG2 and full length Neurocan was increased in the peri-infarct cortex and ipsilateral thalamus at 7 and 14 days (P<0.05). However, there were no significant difference in either expression of CSPGs, NG2 and full-length Neurocan between 7 and 14 days or the expression of C-terminal fragment Neurocan at 7 and 14 days (all P>0.05). Conclusions CSPGs may play a negative role in neural plasticity through induction of inhibitory environment in the peri-infarct cortex and ipsilat-eral thalamus following focal cerebral infarction in hypertensive rats.

Objective To observe the effects of advanced glycated bovine serum albumin(AGE-BSA) on the tubule like structure(TLS) formation of endothelial cells.Methods There were three groups:AGE-BSA(25,50 and 100 ?g/ml) treated groups,BSA(25,50 and 100 ?g/ml) treated groups as BSA control groups,endothelial complete medium without AGE-BSA or BSA as blank control groups.After incubation of human umbilical vein endothelial cells(HUVECs) for 24,48 and 72 h,TLS formation assay and ELISA were used to detect the length of TLS formation on the surface of collagen Ⅰ and the vascular endothelial growth factor(VEGF) autocrine of HUVECs in presence of AGE-BSA.Results In 24 to 72 h,AGE-BSA(25,50,100 ?g/ml) increased the average length of TLS formation on the surface of collagen Ⅰ and the concentration of VEGF autocrine in supernatant of HUVECs(P

BACKGROUND: There are many drawbacks with hormone replacement therapy for menopausal syndrome. The blood levels of 5-HT and norepinephrine are lower. Fluoxetine hydrochlorde(ProzacR) is a selective serotonin reuptake inhibitor which is widely used in treating anxiety and depression,OBJECTIVE: To evaluate the effect of combined antidepressant and estrogen therapy compared to estrogen alone in the treatment of perimenopausal syndrome in this prospective open study.DESIGN: Randomized comparative study.SETTING: Department of Obstetrics and Gynecology of the First Affiliated Hospital of Chongqing Medical University PARTICIPANTS: From November 2003 to December 2004, 60 female patients with diagnosed menopausal syndrome of 3-12 month duration, aged (46±3) years, from Department of Obstetrics and Gynecology of the First Affiliated Hospital of Chongqing Medical University were enrolled into the study after giving their informed consents. The patients were randomly divided into two equal groups with Group 1 (n=30) receiving a combination of antidepressant + estrogen and Group 2 (n=30) receiving estrogen only.METHODS: Patients in Grgup 1 received fluoxetine hydrochloride (ProzacR) 20 mg orally every morning plus oral estradiol 1 mg once every two weeks for 2 months. Patients in Group 2 received only oral estradiol 1 mg once every two weeks for two months. Patients were not taking any other drug during the treatment period. At the end of two month treatment all patients were evaluated with the following 3 assessment tools: ①female menopausal symptom evaluation with the following 4 categories: Complete symptom relief, markedly improved, improved and no effect. Overall efficacy was defined as 50% symptom improvement. ② Hamilton Depression Scale which reflects energy level and psychosomatic factor of sleep and anxiety. ③Menopause index: Which are description of clinical evaluation and adverse effects; this would help to assess the safety of using both drugs in treating the menopausal syndrome.MAIN OUTCOME MEASURES: female menopausal symptom assessment, hamilton depression scale, and menopause index.RESULTS: ① In female menopausal symptom assessment group 1 showed better results in the complete relief and markedly improved scores. ②Hamilton Depression Scale group 1 also showed better scores than Group2(In Groupl, the scores at week 1 to 8 were 25,18,15,10,8,5,5,4 respectively ,in Group 2, the scores at week 1 to 8 were 25,17,15,14,13,12,13,13 respectively). ③ Group 3 showed a significant better score in the menopausal index with improvement in sleep disorder, anxiety and depression than Group 2 (In Group 1 the scores at week 1-8 were 32,22.5,15,15,14,15,15,14 respectively,In group 2, the scores at week 1 to 8were 33,21,16,14,13,12,13,13 respectively) ,there was no significant difference of incidence of adverse events as compared with Group 3 .CONCLUSION: Combined therapy of fluoxetire hydrochlarde(PROZAC)plus estrogen showed better efficacy in the treatment of menopausal syndrome than estrogen alone.

AIM: We sought to evaluate the expression of apoptosis related genes, p53 and bcl-2, in cultured vascular smooth muscle cells (VSMCs) in which apoptosis was induced by the ligands of PPAR?-ox-LDL,ciglitazone and 15-deoxy-△ 12,14-PGJ 2,and then influenced by PGF 2?,an antagonist of PPAR?. To clarify whether PPAR? is involved in the regulations of p53 and bcl-2.METHODS: Rat aorta smooth muscle cells were isolated and cultured in DMEM containing 10%FBS. ox-LDL,ciglitazone and 15 d-PGJ 2 were added into the medium for 24 h, respectively. Using PGF 2? to inhibit PPAR? activation via activation of MAP kinase. We employed the flow cytometry analysis to quantitatively analyze the apoptosis of VSMCs. Also, we measured and analyzed the discrepancies of the expression of p53 and bcl-2 between every groups. RESULTS: During the process of apoptosis induced by PPAR?,the expression of P53 protein increased (P

Objective: Based on supramolecular imprinting template self-recognition theory, to lay the foundation for the in vitro channel tropism research methods of Chinese materia medica (CMM). Using alizarin as imprinting template feature monomer, in vitro affinity chromatography of different pig organs was performed to test the mechanism of alizarin belonging to the liver meridian. Methods: The liver, lungs, tongue, abdominal muscle, leg muscle groups, and other tissues of pigs, as stationary phases, were made into column chromatography. Using PBS as the mobile phase, in vitro affinity chromatography experiments with alizarin belonging to the liver meridian and white sugar belonging to the spleen meridian were conducted, the content of eluent alizarin was measured by HPLC and the content of sugar was measured by UV. By using the analysis of total statistical moment, the various chromatographic parameters and chromatography equations were obtained. Results: The chromatographic parameters for the alizarin in liver, lungs, tongue, abdominal muscles, leg muscles were as following: C0: 0.2509-4.813 mg/mL; AUC: 2.509-48.13 mg; VR: 20.42-30.77 mL; σ2: 282.6-532.7 mL2; H: 14.13-26.63 mL; n: 1.212-1.777; S: 0.759 0-1.000. In the positive control group, the adsorption capacity of liver for alizarin was the strongest, and abdominal, leg, lungs, and tongue were weakened in turn. While in the negative control group, the adsorption capacity of liver for glucose (white sugar) was not the strongest. Conclusion: The adsorption capacity of liver for alizarin is the strongest, and liver has an affinity for alizarin by the super molecular imprinting templates, and it matches the theory of meridian belonging to the liver, which would establish the in vitro channel tropism preliminary research methods of CMM.
