1.Advancement in bladder cancer markers in urine
China Oncology 2009;19(7):557-561
Bladder cancer is a common type of tumor in the urinary system. Its incidence has been increasing and the disease has a high rate of recurrence. Cystoscopy and cytology are the main methods for the diagnosis and the early detection of recurrence for bladder transitional cell carcinoma. Since cystoscopy is expensive and invasive, and although cytology is non-invasive but it is not very sensitive, many tumor makers have recently been studied in the diagnosis of the disease. So how to choose tumor makers with high sensitivity and specificity for the diagnosis of the disease so that the patients with bladder cancer could be treated at the earliest stages is important, the biomarkers may play a very important role in clinical application. In this review we discussed the development of biomarkers for bladder cancer.

China Oncology 2010;20(2):156-160
The high mobility group A2 (HMGA2), one ofnon-histone chromatin proteins, may alter chromatin structure and thereby regulate the transcription of several genes by either enhancing or suppressing transcription factors, and leading to malignant neoplasm formation. This paper focuses on the role of the HMGA proteins in human neoplastic diseases, and discusses the mechanisms by which they contribute to carcinogenesis, and diagnosis strategies based on targeting HMGA proteins.

Objective o observe the therapeutic effects of suspension-assisted functional rehabilitation training of motor function for patients with cerebral infarction. Methods Ninety-six patients with cerebral infarction were divided randomly into a treatment group and a control group. All patients were given routine medical treatment and routine limb movement therapy. Those in the treatment group also used an electrically-driven suspension device to aid in their functional rehabilitation training. The patients were assessed with a simplified Fugl-Meyer Motor Functional Assessment (S-FMMFA), and using the Postural Assessment Scale for stroke patients ( PASS), the Barthel Index (BI) and the 6-minute walking distance test before and after treatment and at a 6-month foliowup. Results The average S-FMMFA, PASS, BI and the 6-minute walk results in the treatment group were all significantly better than those in the control group. Conclusions Suspension-assisted training can significantly help improve limb movement function and ADL performance in cerebral infarction patients.

Objective To investigate the expressions of advanced glycosylation end products (AGE) in skin of mice with diabetes mellitus (DM) for different durations,and to evaluate their influence on collagen fibers.Methods Forty healthy 8-week-old male C57BL/6J mice were divided into DM group (n =20) and control group (n =20) to receive multiple intraperitoneal injections of low dose streptozotocin (50 mg/kg) and citric acid buffer (0.1 mol/L),respectively,for 5 consecutive days.Ten mice were sacrificed in each group on week 4 and 12 respectively after the last intraperitoneal injection,and full-thickness skin tissue samples were harvested from the middorsal region of each mouse.Then,hematoxylin-eosin (HE) staining was performed to observe histological changes,and total collagen content was estimated according to hydroxyproline content measured by an alkalinehydrolysis method.The cross-linking degree of collagen was determined by Edman degradation method using pepsin,the mRNA expression level of collagen type Ⅰ and Ⅲ by real-time quantitative PCR,the content of AGE by fluorospectrophotometry and Western blotting,and the level of malondialdehyde (MDA) by using a thiobarbituric acid method.Statistical analysis was carried out by t test.Results As light microscopy showed,the skin became obviously thinner in the diabetic mice with a progressive decrease in the number of collagen fibers in comparison with the control mice.On week 4 and 12 after the last injection,the diabetic mice exhibited a significant reduction in the content of hydroxyproline ((684.5 ± 76.7) vs.(787.7 ± 87.7) rg/g,(558.1 ± 73.1) vs.(757.8 ± 75.3) mg/g,both P < 0.01) and in the levels of cross-linked collagen as well as mRNA expressions of collagen Ⅰ and Ⅲ (P < 0.01 or 0.05),but a significant increase in the content of AGE ((37.47 ± 10.65) vs.(26.39 ± 3.74) AUF/mg hydroxyproline,(47.70 ± 5.66) vs.(29.91 ± 6.50) AUF/mg hydroxyproline,both P < 0.01) and MDA ((6.62 ± 0.47) vs.(4.82 ± 0.56) μmol/L,(8.63 ± 0.36) vs.(5.15 ± 0.46) μmol/L,both P< 0.01) in skin tissue,compared with the control mice.The level of non-cross-linked collagen in skin tissue was also lower in the diabetic mice than in the control mice on week 12 (P < 0.05).Moreover,the contents of hydroxyproline and the expression levels of collagen I in skin were significantly lower (P < 0.05),but the levels of AGE and MDA were significantly higher (P < 0.01) in the diabetic mice on week 12 than in those on week 4.Conclusions The characteristics of collagen fibers in skin are altered in diabetic mice when compared with normal control mice,which may be associated with increased AGE content and oxidative injury in skin.
