AIM:To analyze the effect of non-exchange transfusion therapy, including simple phototherapy or phototherapy combined with albumin therapy, on severe jaundice in full-term neonates.METHODS: The full-term neo-nates (n=110) with serum total bilirubin (TBIL) level over 342 μmol/L recewed simple phototherapy or phototherapy combined with albumin therapy.The changes of serum bilirubin levels and neurological signs of these neonates were ob-served.RESULTS:Serum TBIL and indirect bilirubin ( IBIL) levels in the 2 groups of hospitalized cases significantly re-duced after the first day of treatment and at discharged (P<0.01).The reduced degrees of TBIL and IBIL levels in the neonates given phototherapy combined with albumin therapy were higher than those in the neonates given simple photothera-py.All these neonates did not have bilirubin encephalopathy on admission or at discharged.CONCLUSION:Both simple phototherapy and phototherapy combined with albumin therapy treat severe jaundice effectively and prevent acute bilirubin encephalopathy in full-term neonates.

Oral cancer is a common cancer of head and neck. Regional recurrence and metastasis are the main course of the poor prognosis. But the exact molecular mechanism is still unknown. Studies have showed that microRNA plays an important role in the tumorigenesis, invasion and metastasis of oral cancer. And it is expected to become a valuable diagnostic marker and therapeutic target. This paper makes a review about the microRNA related to oral cancer.

This paper introduces the basic concept of man-machine interaction technique and the pathological and physiology basis of its application in guiding equipment. Based on the analysis of demands of blind people, the design for novel intelligent guiding equipment based on man-machine interaction technique was proposed. This method used multiple sense information mainly by infrared technique to detect obstruction and control the advancing direction of whole guiding equipment through the intellectualized judgment and processing by microprocessor to guide the blind. In addition, the principle and process of detecting method, control function, command definition, program design and debugging improvement of the guiding equipment were introduced, and its application and prospect were discussed.

The levels of ?_2-m、IgG and Alb in CSF of 13 patients with cerebral haemorrhage and 20 patients with cerebral thrombosis and the levels of ?_2-m in CSF of control group consisting of 14 eases were measured. It Was showed that the levels of ?_2-m in CSF of the two groups of the patients with cecrebrovascular disease were obviously higher than that of the control group and the levcls of ?_2-m in CSF of the two groups of the patients with cerebrovascular discase also had rclation to the levels of ?_2-m in serum of the groups of the patients themselves, the valucs of ?_2-m did not corre- lated with the valucs of IgG or Alb in CSF of the paticnts with cerebral hacmorrhage, but there existed a strong correlation between IgG and Alb in CSF of these patients. The values of ?_2-m, IgG and Alb in CSF of patients with cerebral thrombosis were exactly inversdy correlated with that of patients with cerebral haemorrhage. Reviewing some other data about ?_2-m the authors suggest that the clevated ?_2-m in CSf may indicate an increased cell-mediated immune phenomenon of central nervous system in teh pathological process of cerebral haemorrhage, but this phenomenon in the pathological process of cerebral thrombosis is not obviuos.

Objective: To investigate the relationship between the expression of Raf-1 and tumor angiogenesis,and to discuss its clinical significance.Methods: Tissue microarray technique was used to detect the expression of Raf-1 in 87 specimens of human colon carcinoma,their corresponding adjacent tissues,and incision margins.The patients were from the Department of Pathology of Xijing Hospital between 2005 and 2006.Microvessel density(MVD) was detected using immunohistochemistry with CD34 labeling.The correlation between Raf-1 expression and MVD with the tumor size,metastasis,and differentiation was analyzed.Results: The positive rates of Raf-1 in colon carcinoma tissues,adjacent tissues and incision margins were 86.47%,37.34% and 11.03%,respectively;there were significant difference among the 3 values(P

AIM To study the influence of four extracts of traditional Chinese medicinal materials(sodium cantharidinate, matrine, cinobufotain and sodium ferlate) on the proliferation of human lung cancer A549 cell line and breast cancer MCF7 cell line;the possible mechanism of sodium ferlate on the inhibition of A549 cells. METHODS The inhibition of cell proliferation was determined by MTT assay and cell cycle was determined by flow cytometry. RESULTS All four extracts of traditional Chinese medicinal materials showed growth inhibition to breast cancer MCF7 cells while only sodium ferlate showed inhibition to lung cancer A549 cells. Synergistic inhibition was found when sodium ferlate was combined with each of the three commonly-used chemotheraputic drugs. Sodium ferlate could induce A549 cell apoptosis. CONCULSION The inhibition of cell proliferation induced is by sodium cantharidinate, matrine, and cinobufotain is quite different between different cancer cell lines. Sodium ferlate can inhibit cancer cell proliferation and show synergistic action while combined with chemotheraputic drugs. The mechanism of sodium ferlate on A549 cell proliferation seem to be related to the cell apoptosis.
