Objective To investigate the significance and expression of PTEN, MLL in T lymphoblastic lymphoma/leukaemia(T-LBL/ALL). Methods Seventy-six cases of T-LBL/ALL were studied by using immunohistochemical EnVision method for PTEN. Fluorescence in-situ hybridization (FISH) for MLL gene (located on chromosome 11q23) was performed to detect its breakage and amplification. Results Among the 76 cases ofT- LBL/ALL, the positive rate of PTEN was 64.47 % (49/76), lower than that in reactivated lymphoid tissue (100 %, 20/20) (λ2= 19.220, P ＜0.05). PTEN expression was reversely correlated to theclinical stage, Ki-67 index and LDH level (P ＜0.05). Among the 76 cases, MLL gene with breakage of 11q23 was detected in 13 cases (17.11%), and amplification in 18 cases (23.68 %). Survival rate ot MLL gene breakage group was lower than that of non-breakage group (25.0 %, 43.6 %). Survival rate of MLL gene amplification group was lower than that of non-amplification group too (17.1%, 42.7 %). Both of breakage and amplification were related to prognosis ( λ 2 = 11.357, λ 2 = 4.533; P ＜0.05). Conclusion Anti-oncogene PTEN down-regulation may play an important role on the development and proceeding of T-LBL/ALL. MLL gene with breakage and amplification of 11q23 are helpful to predict prognosis of T-LBL/ALL. The case with MLL gene breakage and amplification of T-LBL/ALL may have a poor prognosis. It hints this group maybe a subtype of T-LBL/ALL.

ObjectiveTo evaluate the relationship between the proliferation of parathyroid cell in rabbit with primary hyperparathyroidism (PHPT) and the bone mineral density (BMD). MethodsEighty adult Chinese rabbits were randomly and equally divided into two groups. The contrast group was fed with normal diet ( Ca ∶ P, 1.0 ∶ 0. 7 ) and the experimental group was fed with high phosphate diet ( Ca ∶ P,1.0∶7.0) to establish the animal model of PHPT. At 3, 4, 5, and 6 months after the diet, bone mineral density of the rabbits was measured by the quantity CT (QCT). Then, the parathyroid and bone of the rabbits were removed for pathological examination. The number of parathyroid cell in PHPT was calculated.Proliferation was determined by immunohistochemistry of proliferation cell nuclear antigen ( PCNA ) and Bcl-2. The t test and Logistic regression was used to analyze the difference of data of two groups. ResultThe number of parathyroid cell in PHPT group was 1.61 times than that in the contrast group[ (673 ± 151 ) HP,(418 ± 25 ) HP,P ＜0. 01]. The rate of PCNA positive-cell was significantly increased in PHPT group than that in contrast group [(50.52 ± 11.62)％o, (26.70 ± 2. 78 )％, P ＜ 0.01], and so was Bcl-2[ (460. 37 ± 190. 05 )‰, (67. 02 ±:4. 38 )％‰,P ＜0. 05]. The value of BMD was significantly decreased in PHPT group than that in contrast group [ ( 152. 5 ± 34. 3 ), ( 188.6 ± 12. 2 ) g/cm3, P ＜ 0. 05]. There was a negative correlation between BMD and PCNA (r ＝ -0. 749, P ＜ 0. 05 ) and between BMD and Bcl-2 (r ＝-0.800, P ＜ 0. 05 ) in PHPT group. ConclusionThe BMD of PHPT is related to the parathyroid cells proliferation which provide a reliable method for early diagnosis of PHPT.

OBJECTIVE: To establish a multidrug-resistant cell line BEL-7402/5-FU of hepatocellular carcinoma (HCC). METHODS: BEL-7402/5-FU was induced by pulse therapy combined with continuous stepwise exposure to 5-fluorouracil in vitro. MTT assay was used to determine its multidrug resistance (MDR). Biological characteristics of the BEL-7402/5-FU cell line were observed including morphological changes, cell growth curve, population doubling time, plate cloning efficiency, adherence rate, cell cycle distribution, chromosome and tumorigenicity. Accumulation amount of adriamycin (ADM) in cytoplasm was measured by flow cytometry. The protein expression of thymidylate synthase (TS) was evaluated by immuno-cytochemical method. RESULTS: The acquired MDR cell line of BEL-7402/5-FU was established successfully. The BEL-7402/5-FU cells showed cross-resistance to ADM, vincristine (VCR), methotrexate (MTX) and oxaliplatin (OHP), whereas still sensitive to hydroxycamptothecin (HCPT). The BEL-7402/5-FU cells tended to grow in clusters in vitro. It was found that the population doubling time of BEL-7402/5-FU cells was longer than that of its parental cells. The plate cloning efficiency and the adherence rate of BEL-7402/5-FU cells at the 2nd and 3rd hour were both lower than those of the parental cells. The distributing proportion of BEL-7402/5-FU cells in G(0)/G(1) phase was less than that of the parental cells, whereas the distributing proportion of BEL-7402/5-FU cells in S phase was higher than that of the parental cells. The accumulation amount of ADM in cytoplasm of BEL-7402/5-FU cells was significantly lower while the expression level of TS protein of which was highly up-regulated as compared with those of the parental cells. CONCLUSION: Establishment of the human HCC cell line BEL-7402/5-FU might be beneficial to the studies of 5-Fluorouracil acquired MDR mechanisms and the selection of reversal modifiers.

Objective To observe change of T regulatory cells (Tregs) and its relation with in-jury severity and sepsis following severe muhiple injury. Methods A total of 60 patients were em-ployed in the study and divided into severe group (30 patients) and critical group (30 patients) based on ISS scores and into sepsis group (22 patients) and non-sepsis group (38 patients) based on complication of sepsis. The proportion of Tregs in peripheral blood in different groups was detected by flow cytometry at days 1,3,5 and 8 after injury. Results The proportion of Tregs was significantly increased at day 5 postinjury, with statistical difference compared with that at day 3 postinjury (P < 0.01). The proportion of Tregs remained increasing at day 8 pestinjury (P < 0.05). At day 8 postinjury, the proportion of Tregs in critical group was significantly higher than that in severe group (P < 0.01). At the same time, the proportion of Tregs in sepsis group was significantly higher than that in non-sepsis group (P < 0.05). Spearman correlation analysis showed a positive correlation of Tregs proportion with ISS score (rs =0.654, P < 0.01). Conclusions Tregs play an important role in suppression of T cell-mediated im-munity after severe injury. The variation of Tregs can help evaluate prognosis and predict the risk of com-plicating sepsis in patients with severe multiple injury.
