Objective: To investigate estrogen receptor (ER) and progesterone receptor (PR) in the tumor derived from non-target organ (primary bronchogenic carcinoma), and correlation with the tumor. Methods: According to WHO histo-logical classification of lung tumors, 146 resected specimens of lung canrer were examined microscopically; ER and PR were detected on paraffin-embedded tissue sections using immunohistochemical staining. Results: 58.9% of the cases were positive for ER, 69. 1 % for PR,and 46.6% positive for both. There was a significant correlation between ER and PR positive percentage and degrees of histological differentiation in lung cancer, while ER and PR percentage appears to have no relationship with histological type, tumor size, age and sex of the patients. Conclusion: It is demonstrated that ER and PR are present in non-small cell lung cancer. These observation may provide a basis for adjuvant hormonal therapy in selected lung cancer patients.

Objective To analyze contrastly the effect of 89SrCl2 for bone metastasis in Uygur and Han patients with prostate cancer.Methods The curative effects in 75 Uygur and 82 Han patients with prostate cancer bone metastasis were investigated after intravenous injection with 89SrCl2,including palliation of pain.SPECT was used to detect the change of metastasis,level of prostate-specific antigen (PSA) and interleukin-6 (IL-6) were detected by electrochemiluminescence immunoassay.Results After treated with 89SrCl2,the palliation rate,the bone metastases and the level of IL-6 were higher in Uygur patients [82.67 ％ (62/75),75 ％ (56/75),(4.24±1.74) pg/ml] than those in Han patients [60.98 ％ (50/82),52.44 ％ (43/82),(2.81±2.38) pg/ml],and there were statistically significant (P ＜ 0.05).Conclusion 89SrCl2 is more effective for the Uygur patients with prostate cancer bone metastasis than the Han patients,clinical workers should pay more attention to this.

Objective To evaluate the diagnostic value of multi-slice computed tomography (MSCT)for incisional hernia of ab-dominal wall before operations.Methods Thirty patients with incisional hernia in abdominal wall confirmed by the pathology were enrolled in this study.All patients underwent MSCT examination with sagittal and coronal MPRs,and 21 cases underwent ultra-sound (US)examinations.The value of transverse scan and MPRs & MSCT and US on demonstrating the number,location,con-tents of incisional hernia,and accompanying intestinal obstruction or other complications were retrospectively evaluated and com-paired.Results Of 30 cases,there were 40 hernias,the rate of MSCT and US in detecting incisional hernias were 97.5% and 56.0%, respectively.MSCT performed better than US on demonstrating the incisional hernias (P =0.000).On MSCT,there was no signif-icant difference in the detection for isolated incisional hernia between the MPRs and axial scans (P = 1.000 ).However,MPR showed a more accurate rate for two or multiple incisional hernias diagnosis (P =0.006),and the sagittal reconstruction displayed more correct than coronal reconstruction on two or multiple incisional hernias (P =0.01 9).Furthermore,MSCT can exactly reveal the complications of incisional hernias (7 cases of intestinal obstruction,5 cases of intestinal ischemia and edema,and 1 case of me-tastasis in incisional hernia),which were not detected by US.Conclusion MSCT can correctly demonstrate the incisional hernia of abdominal wall and its complication,it can provide important imaging reference for clinical therapy.

Objective:To analyze the differentally expressed long non-coding RNA (lncRNA) among mice of different ages and explore the mechanism of kidney aging.Methods:Male C57BL/6 mice aged 3-month-old ( n=5), 12-month-old ( n=5) and 24-month-old ( n=5) (each weighting about 25 g) were randomly selected. PAS staining, Masson staining and senescence associated β-galactosidase (SA-β-gal) staining were used to detect the pathology and cell senescence of mice kidney. High throughput sequencing was performed to detect the differentially expressed lncRNA and their fragments per kilobase million. Real-time quantitative PCR was used to verify the differentially expressed lncRNA. Competitive endogenous RNA (ceRNA) network, which consisted of lncRNA, miRNA and mRNA was built. GO and KEGG enrichment analysis method were used to predict the biological function of differentially expressed lncRNA. Results:PAS staining and Masson staining showed the development of kidney fibrosis, and SA-β-gal staining positive region was increased significantly as age increased. There were 938 known lncRNA and 542 novel lncRNA differentially expressed among different ages' mouse kidney. Compared with 3-month-old mice, 33 lncRNA were up-regulated and 43 lncRNA were down-regulated in 12-month-old mice. Compared with 3-month-old mice, 130 lncRNA were up-regulated and 91 lncRNA were down-regulated in 24-month-old mice. Compared with 12-month-old mice, 36 lncRNA were up-regulated and 22 lncRNA were down-regulated in 24-month-old mice. The results of qRT-PCR about verified 10 lncRNAs with larger differential expression multiples and higer expression levels were consistent with the sequencing data. GO enrichment analysis showed that the target genes of lncRNA differentially expressed in the three groups were mostly located in the nucleus and cytoplasm, and might play a role by binding to proteins or participate in various protein phosphorylation, cell cycle, transcription, transcription regulation and other processes. KEGG enrichment analysis showed that the target genes of lncRNA differentially expressed in the three group were significantly enriched in Rap1 signaling pathway, FOXO signaling pathway and MAPK signaling pathway, which were closely related to kidney aging.Conclusion:There are significant differences in expression of lncRNA among the kidney of different ages mice, which are involved in the occurrence of renal senescence.

BACKGROUND: Recent study showed that osteocalcin may elevate Insulin secretion and sensitivity, prevent the fat accumulation, play a role in the metablism of glucose and lipid. Undercarboxylated osteocalcin works as the main role. OBJECTIVE: To investigate the effect of different concentrations of glucose on osteoblast undercarboxylated osteocalcin. METHODS: The rib trabeculae were resected and broken, trypsinizated and washed completely by PBS. Bone surface and non-adhesive floating cells in cleaning fluid were observed with inverted microscope. Rib trabeculae was washed by DMEM culture medium once, and cultured in culture bottle. The culture liquid was replaced by new one once a week. The osteoblast was moved from the scledte a week later. The cells were fused monolayer and could be subcultured 4 to 6 weeks later. The active second or third generation cells were inoculated to 6-pore plate forming 5 groups. Osteoblast were stimulated by 5.6 mmol/L., 7.6 mmol/L, 9.6 mmol/L, 12.6 mmol/L, 20.6 mmol/L glucose medium respectively after the 80% cells were fused, the vitamin K_2 was added into the culture liquid until the concentration of it to be 10~(-5) mol/L. Supernatant was collected after half hour culturing, the undercarboxylated osteocalcin level were detected with RIA test kit, and corrected it as the total the undercarboxylated osteccalcin, calculated the carboxylated incomplete osteocalcin rate. RESULTS AND CONCLUSION: The rate of ostecblast carboxylated incomplete osteocalcin was different under different concentration glucose. The rate of 7.6 mmol/L, 9.6 mmol/L, 20.6 mmol/L concentration glucose groups were higher than that of 5.6 mmol/L glucose group [(0.27±0.02)%, (0.29±0.04)%, (0.12±0.02)%, P < 0.05]. It is indicated that osteoblast could sense the change of glucose concentration by regulating the secretion of the undercarboxylated osteocalcin between the concentration of 5.6mmol/L to 9.6mmol/L, while the carboxylated incomplete osteocalcin decreased as the concentration of glucose increased.
