Journal of Chongqing Medical University 1986;0(03):-
Objective:To investigate the differential expression of VEGF165b in the renal cell carcinoma (RCC) and normal renal tissues and its role in the development of RCC. Methods: S-P immunohistochemistry was used to detect the expression of VEGF165b protein in 30 specimens of paraffin-embedded RCC tissues and 29 specimens of paraffin-embedded normal renal tissues. RT-PCR was performed to detect the expression of VEGF165b mRNA in 32 specimens of fresh RCC tissues and 30 specimens of fresh normal renal tissues. Results: Among 29 of normal renal tissues,28 specimens had positive expression of VEGF165b protein,with the positive rate of 96.55%(28/29) that was significantly higher than 20.00%(6/30)in RCC tissues(P

Objective:To investigate the differential expression of VEGF165b in the transitional cell carcinoma of the bladder (TCCB) and normal bladder tissues and its role in the development of TCCB. Methods: S-P immunohistochemistry was used to detect the expression of VEGF165b protein in 38 specimens of paraffin-embedded TCCB tissues and 36 specimens of paraffin-embedded normal bladder tissues. RT-PCR was performed to detect the expression of VEGF165b mRNA in 55 specimens of fresh TCCB tissues and 43 specimens of fresh normal bladder tissues. Results: Among 36 of normal bladder tissues, 35 specimens had positive expression of VEGF165b protein, with the positive rate of 97.22% (35/36) that was significantly higher than 21.05% (8/38) (P

Objective To investigate the characteristics of stem cells marked with bromode oxyuridine (Brdu) and telomerase reverse transcriptase (TERT) in lung tissue, as well as its effects on pulmonary development and injury-repair. Methods A model of hyperoxia in neonatal rats was established by exposed to 95% O2 for 7 days. Before executing rats, Brdu was injected peritoneally, then Brdu and TERT positive cells were detected by immunohistochemistry. Results (1)The positive staining cells of Brdu with large nuclear located in septa and submucose of series bronchia, scattering in epithelium of bronchia, and the number of positive cells were less. The positive staining cells of TERT located in the septa and alveolar walls of peripulmonary tissue and the number of which was less than that of Brdu. (2)The positive cells of SPC located in septa and alveolar walls. Staining with Brdu and TERT, small number of positive cells was observed. (3) In hyperoxia and normal oxygen group, integral of expression of Brdu, TRET and SPC had no differences. But integral of expression of Brdu in whatever hyperoxia (1. 61?0. 83) or normal oxygen group (1. 43?0. 85) were higher than TRET and SPC (P

Objective To study the effect of dexamethasone on KGF expression in lungs of neonatal rats after hyperoxic exposure. Methods A randomized controlled study was designed in 48 Sprague-Dawley neonatal rats of 3 days old and divided into hyperoxia group, hyperoxia + dexamethasone and control groups for 7days. Histologic examination of the lung tissues were studied and radical alveoli count (RAC) were determined after HE staining. KGF expression was detected by immunohistochemistry. Results (1)The lungs of the rats in the hyperoxia group showed thinner walls of alveoli, simple alveolar structure, fewer and larger alveoli, expanded and shrinked alveoli. While those rats in the dexamethasone group showed more severe changes and some destroyed septa and walls of alveoli which lead to structure turbulence of the pulmonary tissue. The RAC in the hyperoxia and dexamethasone group was siginificanly lower than that in the control group (9.50?1.05, 10.03?3.26 vs 13.00?1.79, P

Objective To investigate the relationship between abnormal bone mineral density (BMD) and subclinical thyroid dysfunction. Methods Thyroid function, biochemical indicators of bone metabolism and BMD were reviewed retrospectively in the subjects who received health checkups from July 1, 2009 to January 31, 2017 in the Health Check-up Department of Peking Union Medical College Hospital. People who had thyroid dysfunction, recognized risk factors for osteoporosis, and medication history were excluded. A cross-sectional analysis of thyroid status and biochemical indicators of bone metabolism was performed by the standard methods. BMD at the lumbar spine and femoral neck was measured using dual energy X-ray absorptiometry. Results A total of 6884 subjects (3726 women and 3158 men) were enrolled in the study, with an average age of (50.74 ± 10.41) years. They were divided into three groups:subclinical hyperthyroid, subclinical hypothyroid, and euthyroidism. The alkaline phosphatase in subclinical hyperthyroid group was higher than that in the euthyroidism group[ (67.95±20.64)U/L vs. (63.88±18.99)U/L]. Calcium and phosphorus in blood were higher in both subclinical hyperthyroid and subclinical hypothyroid groups. The rate of abnormal BMD in male euthyroidism, subclinical hyperthyroid and subclinical hypothyroid groups were 36.10%(1049/2906), 29.27%(12/41) and 27.01%(57/211), respectively. The rate of abnormal BMD showed no difference between subclinical hyperthyroid group and euthyroidism group (P>0.05). The rate of abnormal BMD was lower in subclinical hypothyroid group than in euthyroidism group (χ2=7.0901, P<0.01), especially in the males aged 40-49 years (χ2=10.4618, P<0.01). The rate of abnormal BMD in female euthyroidism, subclinical hyperthyroid and subclinical hypothyroid groups was 38.81%(1286/3314), 45.83% (33/72) and 40.88% (139/340), respectively. The rate of abnormal BMD showed no difference among the three groups (P>0.05). Conclusion There is no significant difference in the rate of abnormal BMD between subclinical thyroid dysfunction group and euthyroidism group, possibly because abnormal serum biochemical indicators preceded the presence of low BMD. More sensitive methods used to determine the status of bone metabolism await to be developed.

Objective To investigate the clinical features of anterior pituitary hypofunction.Methods A retrospective analysis was carried out on the data of 117 patients with anterior pituitary hypofunction during 1994-2010.Results There were 60.68% male and 39.32% female patients respectively.The onset age was from 13 to 79 years,with 79.12% of the patients more than 40 years old.There were 57 cases with sellar tumors ( 40.17% ),in which 55 cases( 96.49% )were operated and (or) treated with radiotherapy.35 cases were operated via the frontal approaches( 66.04% ) and 18 cases underwent transsphenoidal surgery ( 33.96% ).There were 108 cases with hyponatremia with the first symptoms of weakness,anorexia,nausea,and vomiting induced by ACTH deficiency (92.31% ).There were 23 cases accompanied with central diabetes insipidus( 19.66% )and 82 cases with coronary heart disease( 70.09% ).Conclusion Owing to the difference in etiological factors,the incidence,early symptoms,and the hormones involved are greatly different.The main cause is pituitary tumor,which occured more in aged person,more in males than females.

Thyroid B-ultrasound and urinary iodine content were examined in 4390 male workers aged 18-62 years-old,who participated annual physical checkups in 2009 and 2010.The results suggest that there is no obvious relationship between the urinary iodine which represents the iodine intake within 24 hours and prevalence of thyroidnodale.However,the prevalence of thyroid nodules shows an upward trend with the advance of age.
