PURPOSE To sutdy the effects of dibutyl pathalate (DBP) on the proliferation and apoptosis of leukemic cells from patients suffering from acute leukemia. METHODS The cell culture in vitro was used to study the effect of DBP on the proliferation of leukemic cells, while agrose gel electrophoresis of DNA fragments was used to study the effect of DBP on apoptosis of leukemic cells. RESULTS DBP could inhibit the proliferation of leukemic cells got from patients suffering from acute leukemia in vitro. The percentage of inhibition were 24.24% and 36.33% respectively when leukemic cells were exposed to 50?g/ml and 200?g/ml DBP for 24 hours. Leukemic cells from acute myelogenous leukemia were more susceptive to DBP than those from acute lymphocytic leukemia. DBP also induced the leukemic cells from patients to die via apoptosis and showed typical "ladder" of DNA fragments for apoptotic cells in agrose gel electrophoresis. CONCLUSION DBP could clear the leukemic cells in bone marrows of patients suffering from acute leukemia by suppressing the growth of leukemic cells and inducing them to die via apoptosis.

Physical constitution theory is an important part of traditional Chinese medicine theory. Physical constitution is associated with the incidence, development and prognosis of diseases. Gene polymorphism is a result of the interaction between internal and external environments during the human evolution, and it is the reason for differences in biological characteristics and disease susceptibility of individuals. Current status of the research on physical constitution theory, lung cancer syndromes and gene polymorphism are summarized in this paper. Exploring lung cancer syndromes from the point of view of gene polymorphism may reveal the scientific connotation of lung cancer syndromes, and provide new evidence and method for diagnosis of lung cancer.

AlM: To observe the influence ofphacoemulsification on corneal endothelial cell in patients with the different level of HbA1c.METHODS:With case-control study, 164 eyes from 115 cataract patients were divided into four groups according to the preoperative HbA1c level. Control group A: 43 eyes from 30 cases without diabetes ( HbA1c≤6. 5%). Diabetes groups:group B was consisted of 38 eyes from 26 cases(HbA1c≤6. 5%), 40 eyes of 28 case was in group C (6. 5% 8. 0%). Corneal endothelial microscopy was used to detect the parameters like endothelial cell density ( CD ) , coefficient of variation ( CV ) , percentage of regular hexagonal cells (6A) between pre-operation and post-operation at 1d, 1, 2wk, 1mo. The results were analyzed.RESULTS: The endothelial cell density, CV and 6A cell had no significant difference in four groups before treatment (P>0. 05). The CD and 6A were decreased and CV was increased in all groups after operation of 1d, 1, 2wk and 1mo. The difference was statistically significant (P< 0. 05). There were statistical differences of 6A and CV in diabetes groups compared with control group ( P<0. 05). The decreasing of CD between group A and group B had no difference (P>0. 05). There were statistical differences of CD in group C and group D compared with group A (P<0. 05). There were statistical differences of CD, 6A and CV within diabetes groups (P<0. 05). CONCLUSlON: Cataract phacoemulsification had certain degree damage on corneal endothelial cell. Corneal endothelial appeared the minimal injury when the postoperative HbA1c≤6. 5%. For diabetic cataract patients, the higher HbA1c before, the heavier damaged after the surgery.

Objective To explore the effect of persistent stress on the ultrastructure of cancellous bone in the process of fracture healing.Method A transverse osteotomy on both sides of the femoral tuberositas was performed in 20 adult dogs. One side was fixed with a self-designed tuberositas memofy-pressure connector (TMC) which was made of NiTi shape memory alloy, and the other with compressive steel-wire (SW) cerclage.Five animals in each group were sacrificed at 2, 4, 8, 12 weeks after operation and observed under transmission electron microscope.Results The fracture healing was accelerated in the TMC group.The osteoblasts, chondroblasts and collagen fibers at the fracture sites showed significantly different morphology between the 2 groups at every observation time.Most cells and collagen fibers in the TMC group grew along the same direction as the stress, but those in the SW group grew in disorder.Both the number and functional activity of the osteoblasts and chondroblasts were higher in the TMC group than in the SW group.Conclusion Persistent stress can enhance healing and bone reconstruction following a cancellous bone fracture.
