Objective To investigate the expression of p-MNK1 in non-small cell lung cancer and its relationship with clinic pathological features and prognosis.Methods The level of p-MNK1 in 115 cases of nonsmall cell lung cancer was detected by tissue microarray technique and immunohistochemistry technique.Results The level of p-MNK 1 in non-small cell lung cancer was correlated with cancer tissue type (P ＜ 0.05),clinical stage (P ＜ 0.05),lymph node metastasis (P ＜ 0.01) and prognosis (P ＜ 0.05).Cox multiple regression analysis showed that p-MNK1 expression was an independent prognostic factor for non-small cell lung cancer (P ＜ 0.01).Conclusion The level of p-MNK1 in non-small cell lung cancer is associated with poor prognosis.It can be used as an independent prognostic marker and a new therapeutic target.

In order to improve the interfacial bonding strength of hydroxyapatite/polyurethane implanted material and dispersion of hydroxyapatite in the polyurethane matrix, we in the present study synthesized nano-hydroxyapatite/polyurethane composites by in situ polymerization. We then characterized and analyzed the fracture morphology, thermal stability, glass transition temperature and mechanical properties. We seeded MG63 cells on composites to evaluate the cytocompatibility of the composites. In situ polymerization could improve the interfacial bonding strength, ameliorate dispersion of hydroxyapatite in the properties of the composites. After adding 20 wt% hydroxyapatite into the polyurethane, the thermal stability was improved and the glass transition temperatures were increased. The tensile strength and maximum elongation were 6.83 MPa and 861.17%, respectively. Compared with those of pure polyurethane the tensile strength and maximum elongation increased by 236.45% and 143.30%, respectively. The composites were helpful for cell adhesion and proliferation in cultivation.

Objective To test whether multiplex ligation-dependent probe amplification(MLPA)could be used for the prenatal detection of the most common aneuploidies of chromosomes 13,18,21,X,and Y.Methods 34 cases including 22 blood samples(12 with trisomy 21,1 with monosomy X,one male witll extra Y and 8 healthy persons),4 cord blood samples with Down syndrome and 8 amniotic fluid samples ( 1 with trisomy 21 and 7 normal fetuses)were recruited into this study.All samples were confirmed by karvotype analysis. DNA was extracted from blood and amniotic lysate was incubated with proteinase K.MLPA was used to determine the relative copy numbers.Results The resuhs were available within 48 h and were concordant with karyotype analysis in all but one case of amniotic fluid that was suggested to be triploid sample 69,XXY by MLPA or contaminated by maternal blood.This sample actually was found containing a number of red blood cells after centfifugation in test. In total,the concordance rate with clinical characteristics was 97.1%.The Ratio values of 13,18,21,X in normal samples were approaching 1.0 except chromosome Y having slightly higher variation in relative copy number.The difference of ratio means between the normal and trisomy 21 samples was statistically significant by one-way ANOVA(F=298.906.P=0.000).Conclusion Computer assisted MLPA with high sensitivity is a rapid,simple,automatic and reliable method for detection of common chromosomal aneuploidies.

Objective To observe the effect of different analgesic methods including patient controlled epidural analgesia (PCEA) and patient controlled intravenous analgesia (PCIA) on stress response and anxiety in surgical patients with lower limb fracture. Methods A total of 120 surgical patients with lower limb fractures were employed and divided randomly into Groups PCEA, PCIA and C (40per group). All patients were anaesthetized by using combined spinal-epidural anesthesia. After operation, PCEA and PCIA were applied in the patients of Groups PCEA and PCIA, respectively. No analgesic method was employed in the Group C. The dynamic indices including mean blood press (MAP) and heart rate (HR), blood serum cortisol (COR) and blood sugar (BS) were measured at different time points,ie, T0 ( pre-anesthesia), T1 ( the end of the operation), T2 (24 hours after operation) and T3 (48 hours after operation). The visual analogue pain score was conducted at time points of T1, T2 and T3. The measurement of anxiety score was done at pre-operation and at days 1 and 7 after operation. Results There were no significant changes in HR and MAP of Groups PCEA and PCIA (P＞0.05, compared with T0) at every time point after operation. Whereas, HR and MAP of Group C were increased at time points of T1 and T2 (P ＜ 0.05, compared with T0 ), with statistical difference compared with Groups PCEA and PCIA at the same time points (P ＜ 0.05 ). VAS in Group PCEA was lower than that in Group PCIA at time points of T2 and T3 ( P ＜ 0.05). Meanwhile, VAS in Groups PCEA and PCIA was lower than that in Group C (P＜0. 05). COR and BS in Group PCEA were significant lower than those in group PCIA at time points of T2 and T3 (P ＜ 0. 05 ). Meanwhile, COR and BS in Groups PCEA and PCIA was lower than that in Group C (P＜0.05 or ＜0.01 ). Moreover, the changes were more significant in Group PCIA than that in Group PCEA (P ＜ 0. 05 ). The anxiety score in Groups PCEA and PCIA was lower than that in Group C (P ＜ 0.05). Conclusions Two analgesic methods of PCEA and PCIA can provide safe and effective postoperative analgesia and attenuate the stress response and anxiety in surgical patients with lower limb fracture. Meanwhile, PCEA takes more advantages than PCIA.

OBJECTIVETo understand the laws and characteristics of silicosis incidence of the workers exposed to the uranium dust from 1956 to 2002.

METHODSThe length of employment, age of occurrence of silicosis, and its duration and death age were compared between the uranium miners and uranium geological prospecting teams, and also between the miners exposed to uranium dust and those exposed to mixed uranium dust by single factor analysis method.

RESULTSWith time going on, the length of employment, age of occurrence of disease and its duration and death age were prolonged respectively in the workers exposed to uranium dust. The length of employment and age of occurrence of disease in uranium geological prospecting teams [(10.15 +/- 5.95) and (40.60 +/- 9.86) years respectively] were shorter than those in uranium miners [(14.23 +/- 8.12) and (41.38 +/- 10.98) years], but the duration (P(50)) and death age were longer [(14.29 years vs 12.52 years), (53.69 +/- 10.04) years vs (51.45 +/- 10.85) years respectively]. The length of employment and age of occurrence of disease in those exposed to uranium dust only [(11.78 +/- 8.06) and (38.04 +/- 9.89) years] were shorter than those exposed to mixed uranium dust [(12.74 +/- 6.29) years, (41.40 +/- 10.67) years], but the duration (P(50)) and death age were longer than the mixed uranium dust ones [(14.59 years vs 13.20 years), (53.93 +/- 10.60) years vs (51.82 +/- 10.20) years].

CONCLUSIONThe difference in the occurrence of silicosis in the workers exposed to uranium dust may be attributed to the physical and chemical character of the uranium dust and the different working circumstance.

To observe BAG-1, EGFR, and PARP-1 expressions in invasive breast cancer and its correlation with clini-cal pathological indicators, as well as to evaluate their clinical significance. Methods:The BAG-l, EGFR, and PARP-1 expressions in a tissue microarray of invasive breast cancer and peritumoral tissues were detected through immunohistochemical staining. The clinical and pathological significance of BAG-1, EGFR, and PARP-1 were evaluated. Results:The BAG-1, EGFR, and PARP-1 expression lev-els are higher in invasive breast cancer tissues than in peritumoral tissues (P<0.05). BAG-1 expression in invasive cancer tissues is not related to age, tumor site, lymph node metastases, and clinical TNM staging of patients, but is related to size, grade, ER, PR, and HER-2 expressions and molecular subtype (P<0.05). EGFR expression is related to size, clinical TNM staging, and molecular subtype (P<0.05). PARP-1 expression is related to grade, lymph node metastases, ER, and molecular subtype (P<0.05). BAG-1 expression is not significantly correlated with EGFR and PARP-1 in all cases, but BAG-1 and PARP-1 expressions are positively correlated in tri-ple-negative breast cancer tissues (P<0.05). Results of the univariate analysis revealed that the BAG-1 and PARP-1 expressions and the molecular subtypes are associated with the prognoses of breast cancer patients. Multivariate analysis revealed that BAG-1 and PARP-1 expressions are factors that are independent of the prognosis. Conclusion: BAG-1, EGFR, and PARP-1 overexpressions in human breast tissues suggest that BAG-1, EGFR, and PARP-1 are related to breast cancer development. BAG-1, EGFR, and PARP-1 are poten-tial biomarkers of breast cancer diagnosis and prognosis.
