Objective To investigate the copy number changes on chromosome 3q26. 1 in urothelial carcinoma of the bladder, and to explore its potential clinical significance. Methods The microarray-based comparative genomic hybridization (Array-CGH) approach was used to analyze the genome-wide copy number changes of 35 tumor tissue samples of bladder cancer. To confirm the loss of a small fragment in 3q26. 1 detected by Array-CGH, real-time fluorescent quantitative polymerase chain reaction (real-time PCR) was performed with 57 frozen tumor tissue samples and 34 formalinfixed paraffin-embedded (FFPE) tumor tissue samples. The urine sediment cells collected from 15 healthy volunteers and 29 bladder cancer patients were checked as above. Results The Array-CGH data showed that the copy number loss of a small fragment in 3q26. 1 was detected in 77.1% (27/35)of the tumor tissue samples investigated. Real-time PCR analysis validated this loss of a small fragment of 3q26.1 with high frequencies in both 57 frozen tumor samples and 34 FFPE tumor samples.The percentage of samples exhibiting loss was 78.9% (45/57) and 100. 0% (34/34) respectively.Furthermore, the relative copy number of the 3q26.1 small fragment was significantly lower in the urinary sediment cells of the patients (median=0. 0020), comparing with that of healthy controls (median=0. 0030) (P＜0.01). Conclusions Loss of the small fragment in 3q26.1 could be a characteristic genetic change of urothelial carcinoma of the bladder. It may serve as a potential molecular marker for bladder cancer.

OBJECTIVETo investigate the prevalence of hyperuricemia with hyperlipaemia, high blood sugar and hypertension among elderly people.

METHODSSerum uric acid (SUA), cholesterol, triglycerides, blood sugar and blood pressure were detected in 1320 elderly people and 6107 people at young and middle age.

RESULTSThe mean SUAs in elderly male and female groups were significantly higher than that in young and middle aged male groups respectively (P < 0.05). The prevalence rates of hyperuricemia in elderly male and female groups were significantly higher than in young and middle aged male groups respectively (P < 0.05). The prevalence rates of hyperlipaemia, high blood sugar and hypertension in the elderly people of hyperuricemia were significantly higher than that in the elderly people of normal serum uric acid (P < 0.05). The prevalence rates of hyperuricemia in the elderly people were complicated by hyperlipaemia, high blood sugar and hypertension which was significantly higher than that in young and middle aged people of hyperuricemia (P < 0.05).

CONCLUSIONHyperuricemia is a common disease in elderly people and more attention should be paid to the closer relations among hyperuricemia with hyperlipaemia, high blood sugar and hypertension among the elderly.

Objective To explore the characteristics of human plague using a sero-epidemiologic method in the source of the three rivers area in Qinghai for possible plague control strategies. Methods Investigate human plague sero-epidemiologically in the source of 4 counties in the three rivers area in Qinghai. The human serum would be tested to confirm the sew-positive rate for plague F1 antibody using indirect hemagglutination assay(IHA). Results A total of 2508 local participants were tested in 4 counties, the overall plague sero-positive rate was 2.31%(58/2508). This represents a statistically significant difference with 4 counties(X2=19.30,P<0.01). The sew-positive rate for males and females were 2.54% (32/1261) and 2.09% (26/1247), respectively. There were no statistically significant differences between males and females(X2= 0.65,P 0.05). The sero-positive rate in herdsman, cadre, Tibetan, Hart nationalities were 3.54% (44/1243), 6.47% (11 / 170), 2.40% (56/2335) and 1.47% (2/136), respectively. The sero- positive rate increased with age. The highest titre for human plague serum antibody was 1 : 640. Conclusion There were occult infections of plague in the population on source of three rivers area in Qinghai. Sero-epidemiologic data revealed that the human plague sero-positive rate was closely correlated with the local animal plague.

OBJECTIVETo explore an ideal method for repairing the skin-soft tissue defects according to the different anatomical units of cheek, and find reasonable design principles to transfer the expanded flaps.

METHODSAccording to the location of the defect, we placed 1-3 appropriate expanders nearby, when the flap expanded enough we adopted advanced skin flaps, rotation-advanced skin flaps or transposition skin flaps to repair the defect. In this group of 269 cases, the defects were secondary to hemangioma, various scars, nevus or nevus excision.

RESULTSIn all 269 cheek defects, 305 expanded flaps were developed which included 145 rotation-advanced flaps, 121 advanced skin flaps and 39 transposition skin flaps. 52 of them generated complications, including blood circulation disorder of the distal part of flaps, hematoma, infection, injection, lower eyelid ectropion, expander extrusion and capsule contracture. Mostly, these complications didn't affect the final results.

CONCLUSIONSThe principles presented in this article are the guidelines to treat the skin-soft tissue defect of check with tissue expansion. The satisfied results come from the reasonable flap designs.

The borneol was included with β-CD and prepared Fufang Danshen intestinal adhesion pellets. GC method for determination of borneol in Fufang Danshen intestinal adhesion pellets was established to study its in vitro dissolution and make a comparison with the Fufang Danshen tablet, in this way, the rationality of dosage form was evaluated. The first method of dissolution determination was used for determining the in vitro dissolution of borneol in Fufang Danshen intestinal adhesion pellets in artificial intestinal juice, and Fufang Danshen tablet in artificial gastric juice and intestinal juice, respectively. Result shows: the concentration of borneol in Fufang Danshen intestinal adhesion pellets and Fufang Danshen tablet was 0.79% and 0.80%, respectively. Its in vitro dissolution was nearly 70% within 12 h in Fufang Danshen intestinal adhesion pellets, and in Fufang Danshen tablet, the dissolution was about 60% within 20 min and more than 90% within 40 min, and in artificial gastric juice, was less than 20% within 40 min but more than 80% till 150 min. Research suggests that in comparison with Fufang Danshen tablet, in vitro dissolution of borneol in the Fufang Danshen intestinal adhesion pellets showed an obvious sustained release behavior. The borneol in Fufang Danshen intestinal adhesion pellets was included with β-CD and prepared enteric preparations. To some extent, the stimulation on stomach and intestinal mucosa can be reduced and safety can be improved.

OBJECTIVETo investigate the association of microsurgical anatomy and growth of pituitary tumors with the recovery of visual pathway, and describe the intraoperative protection of the pituitary stalk and visual pathway.

METHODSA total of 113 patients undergoing pituitary tumor surgery were retrospectively analyzed, including 102 with visual disorder and 106 with pituitary dysfunction with the tumor size ranging from 1.9 to 6.8 cm. All the operations were performed via a transpterygoid approach or transfrontal approach.

RESULTSRadical resection of the tumors was performed in 86 cases, subtotal resection in 21 cases, and partial resection in 5 cases. After operation, 133 eyes showed vision improvement (77.8%), 29 showed no vision changes (17%) and 9 had deteriorated vision. Two patients died due to hypothalamic disorder and multiple organ failure.

CONCLUSIONThe arachnoid barrier between the pituitary tumor and visual pathway is an important structure for visual pathway protection during operation. Total separation of the tumor from the visual pathway allows total removal of the tumor. The preoperative localization and intraoperative identification of the pituitary stalk are critical for pituitary stalk protection.
