AIMTo investigate the effect of fractalkine on cell proliferation of cultured rat pulmonary artery smooth muscle cells (PASMCs) in vitro.

METHODSRat PASMCs were cultured in vitro, and treated with different concentrations (10(-10), 10(-9), 10(-8) mol/L) of fractalkine for 12 h, 24 h and 48 h. The cell proliferation was quantified by MTT assay. The cell cycle of PASMCs was measured by flow cytometric(FCM) analysis.

RESULTSMTT assay showed that fractalkine promoted significantly the proliferation of PASMCs, and the effect was concentration-dependent. FCM analysis indicated that fractalkine increased the percentage of S phase and proliferative index (PI). The percentage of S phase and PI of PASMCs were increased after treated with fractalkine for 12 hours, which reached a maximal level at 24 hours.

CONCLUSIONFractalkine promotes rat PASMCs proliferation in a concentration-dependent manner.

Objective To evaluate the clinical application and significance of lengthen-stem bipolar-femur prosthetic replacement for the treatment of old-age patients with intertrochanteric fracture osteoporosis.Methods 28 cases of patients aging from 75 to 99 years old of intertrochanteric fracture osteoporosis treated with lengthen- stem cemented bipolar prosthesis were studicd from March 2000 to December 2006.After taking the blank margin, the bones of different sizes were replaced and the steel wire was fixed.After determining the depth of the front an- gle,the artificial bone was placed.Results After 28 examples attaining the following-up examination for 7 months to 3 years,with an average of 1.5 years,its function according to Harris standard was evaluated 3 months after the operation,8 examples were excellent,13 examples good,5 examples pass,2 examples inferior.The excellent or good rate reached 75% ,with no abnormal cases,no joint dislocation during the followed-up period.1 example had the phantom phenomenon 1 year after the operation.2 examples among the inferior had got more serious internal medicine disease which affected the restoring function.1 example died of the internal medicine disease 1 year after the operation.Conclusion By using the lengthen-stem bipolar-femur prosthetic replacement for the treatment of old patients with inrertrochanteric fracture osteoporosis,the patients will restore quickly after the operation and can carry a heavy load at an early time.The illness complication and the mortality rate will be redaced.But its related disease must be strictly dealt with and the surgery operating skill must be grasped.

OBJECTIVETo evaluate the prevalence of TET2 gene mutation in acute myeloid leukemia (AML) patients, and analyze their clinical characteristics and prognosis.

METHODSPolymerase chain reaction (PCR) and direct sequencing were used to sequence exon 3 to 11 of TET2 gene.

RESULTSAmong 96 AML patients, TET2 gene mutation was detected in 13 (13.54%) patients (95%CI 6.70% - 20.38%). The median age was 54 years in mutated group and 41 years in unmutated group (P = 0.010). Mutated and unmutated patients did not significantly differ in gender, white blood cells (WBC) count at diagnosis, platelet count, PB and BM blast percentage and chromosome karyotype, excepting for hemoglobin level 84 (70 - 108) g/L in mutated group versus 70 (55 - 87) g/L in unmutated group (P = 0.032). TET2 gene mutation had no significant correlation with C-KIT, FLT3, JAK2V617F mutations, but did with NPM1 mutation. TET2 mutated patients had lower CR1 rate and 2-year overall survival than unmutated in non-M(3) patients (P < 0.05).

CONCLUSIONSTET2 gene mutation is more prevalent in older AML patients and has a certain correlation with clinical characteristics and outcome. It may be a molecular marker for poor prognosis in AML.

OBJECTIVETo investigate the changes of thyroxin and monocyte human leukocyte antigen-DR expression in senior patients with sepsis and explore their clinical significance.

METHODSAccording to the 2001 SCCM/ESICM/ACCP/ATS/SIS international sepsis definitions, 125 senior patients with sepsis free of thyroid conditions were divided into non-severe sepsis group (n=86) and severe sepsis group (n=39), with another 30 healthy subjects as the control. Thyroid function was assayed by chemoluminescence method in these patients and monocyte HLA-DR expression was determined by flow cytometry.

RESULTSCompared with the control group and non-severe sepsis cases, the levels of free T3 (FT3), free T4 (FT4), T3, T4 and monocyte HLA-DR expression were significantly lower in severe sepsis cases (P<0.05), but the levels of thyroid stimulating hormone (TSH) were comparable between the 3 groups (P>0.05). The non-severe sepsis cases showed significantly lower levels of FT3, FT4, T3, T4, TSH and monocyte HLA-DR expression than the control group (P<0.05). In severe sepsis group, the levels of FT3, FT4, T3, T4 and monocyte HLA-DR expression showed significant differences between the fatal cases and surviving cases (P<0.05).

CONCLUSIONThe levels of thyroxin and monocyte human leukocyte antigen-DR expression are obviously lower in senior patients with severe sepsis, and their detection may well indicate the severity of the condition and help make prognostic judgment.

OBJECTIVETo evaluate the prevalence and distribution of C-kit, NPM1 and FLT3 gene mutations in patients with acute myeloid leukemia (AML), and to analyze the relationship between the gene mutations and their prognosis.

METHODSMutations in exon 8 and 17 of C-kit gene, exon 12 of NPM1 gene, exon 20 of FLT3-TKD gene, and exon 14/15 of FLT3-ITD gene were detected by direct sequencing. Clinical data was collected and followed up if the patient had accepted treatment in our hospital.

RESULTSAmong the 656 AML patients, mutations in C-kit exon 8 were found in 6 patients (0.9%), C-kit exon 17 in 33 (5.0%), NPM1 in 169 (25.8%), FLT3-TKD in 46 (7.1%), and FLT3-ITD in 178 (27.1%). Six subtypes of mutations were detected in C-kit exon 8, 8 in C-kit exon 17, 11 in FLT3-TKD, 15 in NPM1, of which 5 were not reported before. C-kit exon 17 mutations were more frequently detected in patients with t(8;21) and exon 8 in patients with inv(16) cytogenetic abnormality. No other gene mutations except FLT3 were detected in M(3) patients. NPM1 and ITD mutations were often detected in individuals with normal cytogenetics or M(5) and M(1) of FAB classification, and accompanied with high white blood cell counts in peripheral blood, high blast counts in bone marrow and low CD34 expression. The older the patients were when diagnosed, the more gene mutations and the higher white blood cell count were detected. More mutations were found in individuals with normal karyotype than that with other karyotypes. It appeared that FLT3-ITD was significantly associated with shorter overall survival (OS) (P = 0.004), NPM1 was not significantly associated with OS, but NPM1(+)/ITD(-) patients had the longest OS.

CONCLUSIONSOur results showed that the mutation types and amounts had particular distribution in MICM subtypes, and were associated with white blood cell counts in peripheral blood, blast counts in bone marrow and prognosis. Especially for patients with normal karyotype, the genetic mutations could be new molecule marker.

OBJECTIVETo investigate the value of serum globulin levels before treatment in predicting the prognosis of patients with nasopharyngeal carcinoma (NPC).

METHODSA total of 127 patients with non-disseminated NPC were recruited between January, 2009 and December, 2013 at Nanfang Hospital. The pretreatment serum globulin levels were analyzed with the receiver-operating characteristic (ROC) curve analysis to select the cut-off point for low and high pretreatment serum globulin levels. Kaplan-Meier and multivariable analyses were used to evaluate the predictive value of serum globulin levels.

RESULTSThe ROC curve analysis determined 30.05 g/L as the optimal cut-off value for pretreatment serum globulin level, which was significantly associated with gender (P=0.024) and N stage (P=0.016). Kaplan-Meier analysis showed that a high pretreatment serum globulin level (>30.05 g/L) significantly predicted poor progression-free survival (P=0.019), overall survival (P=0.034) and distant metastasis-free survival (P=0.049); multivariate analysis identified pretreatment serum globulin level as an independent prognostic factor for progression-free survival (HR=2.344, P=0.031).

CONCLUSIONPretreatment serum globulin level may serve as a valuable marker to predict the prognosis of patients with NPC.
