Objective To evaluate the open-set auditory speech perception abilities, to characterize the auditory speech development of children with cochlear implants.Methods 27 congenitally deafened children with cochlear implants were evaluated with Mandarin monosyllable and disyllable lexical neighborhood test(M-LNT-Monosyllable & M-LNT-Disyllable) and Mandarin hearing in noise test for children(MHINT-C) according to the order from M-MLNT easy test,M-MLNT hard test, M-LNT easy test ,M-LNT hard test, MHINT-C quiet condition, MHINT-C noise front condition, MHINT-C noise non-implant side condition to MHINT-C noise implant side condition in sound field.Results 27 CI children have completed M-LNT/M-MLNT, 9 of them could be tested in quiet condition with MHINT, and 7 could be tested in noise with MHINT. There were significant differences between scores of easy and hard words lists of M-LNT and M-MLNT(P

Objective To explore the relationship between osteoporosis knowledge and activities and fear of falling of elderly in the community.Method 420 elders in community were investigated with osteoporosis knowledge assessment tool (OKAT) and the modified survey of activities and fear of falling in the elderly (MSAFFE).Result The overall average score of MSAFFE was (25.36±4.58),and exercise capacity dimension scored higher (13.89±2.41).The overall average score of OKAT was (9.11±3.81).The correlation coefficient of MSAFFE and OKAT was-0.11～ 0.58(P＜0.05).The level of knowledge osteoporosis could explain 24％,18％,16％ variation of activities and fear of falling in each dimension.Conclusion The level of knowledge osteoporosis in the elderly is closely related to activity and fear of falling.Health education should be strengthened to improve the life quality of older people.

OBJECTIVE To study the clinical characteristics of invasive pulmonary aspergillosis(IPA).METHODS Based on the clinical data from 14 IPA cases identified by pathologic examination in the 454th Hospital,the characteristics of IPA were discussed,including the underlying diseases,symptoms,X-ray,CT,the treatment methods and the curative effect.The related literatures were also reviewed.RESULTS All of the 14 patients had underlying diseases.From them 5 were with pulmonary cancer(35.7%),3 with chronic obstructive pulmonary disease(21.4%),2 with pulmonary abscess(14.3%),2 were after chemotherapy for leukemia(14.3%),1 with pulmonary tuberculosis(7.1%)and 1 with diabetes(7.1%).The common symptoms of the 14 cases were febricity,productive cough and hemoptysis.Some of them also suffered with short of breath,night sweat,fatigue,chest pain and losing weight.The air crescent sign showed on X-ray and CT.Soft tissue masses with halo-sign on the margin,dense shadow of small masses within the alveoli,and multi-nodular shadows were also observed.Among 10 patients treated by antifungal medications,only 4 treated otherwise with operation were cured,4 patients died,and 2 patients did not complete the treatment scheme.CONCLUSIONS The patients with immunodeficiency are susceptible to IPA.The clinical manifestations of IPA are non-specific.The final diagnosis depends on the pathologic examination.The only medication is not sufficient for IPA patients.Pulmonary resection should be considered if the prolonged illness or frequent hemoptysis exist.

OBJECTIVETo study clinical effects of the over-articular external fixator combined with limited internal fixation for the treatment of Pilon fractures caused by high energy.

METHODSFrom September 2003 to April 2011, 36 patients with Pilon fractures caused by high energy were treated with the over-articular external fixator combined with limited internal fixator. There were 25 males and 11 females, ranging in age from 16 to 72 years old,with an average of 38 years old. The diagnoses of all patients were determined by conventional X-ray examination or three-dimensional spiral CT examination. The AOFAS scoring criteria was used to evaluate the therapeutic effects. The patients with comminuted fractures were treated with screw or Kirschner wire fixation without uncovering periost so as to enhance stability between fracture end and bone blocks,followed by the fixation with over-articular external fixators.

RESULTSAll the patients were followed up, and the duration ranged from 4 to 27 months, with an average of 13 months. Thirty-two patients got wound healing at the first stage. And the bone union duration ranged from 2 to 6 months, with a mean of 3 months. According to the AOFAS ankle-hindfoot subjective scoring standard, 13 patients got an excellent result, 20 good and 3 fair, with an score of 88.2 +/- 3.6. Twelve patients had infections at pinhole, 5 patients had pinhole pain. One patient had the fixator broken induced by over loading, who was cured after treatment. There were no complications such as nerve or vascular injuries, or osteomyelitis.

CONCLUSIONThe over-articular external fixation combined with limited internal fixation for the treatment of Pilon fractures caused by high energy is an ideal method, which has such advantages as reliable fixation, simple operation, coincidence with principles of biomechanical fixation, and benefit for fracture healing.

Objective To explore the karyotype distribution in elderly patients with acute leukemia (AL) and compare the prognostic characteristics of karyotype by age grouping.Methods Chromosomal karyotypes were analyzed in 215 cases with AL using the short-term culture of bone marrow cells and G-banding technique.Results There were 202 cases with enough mitosis for analysis and 149 cases(73.8％)with abnormal clone in 215 patients with AL.The rates of abnormal clone were 73.0％ (27/37),74.4％(64/86) and 73.4％ (58/79) in patients aged ≤30,31-59 and ≥60 years,respectively,and no difference were found among age groups (P=0.982).Among 171 patients with acute myeloid leukemia (AML) with detected mitosis,there were 41 better-risk cases (24.0 ％) with most frequent aberration of t(15;17) accounting for 65.9 ％,80 intermediate-risk cases (46.8 ％ ) with principal of normal karyotype accounting for 53.8 ％,and 50 poor-risk cases (29.2 ％)with complex karyotype occupied by 84.0％.The karyotype percentage of better-risk,intermediaterisk and poor-risk were 50.0％,36.4％ and 13.6％ in patients aged ≤30 years,24.3％,48.7％ and 27.0％ in aged 31-59 years,and 16.0％,48.0％ and 36.0％ in aged ≥ 60 years,respectively.The rate of better-risk karyotype was higher in patients aged ≤30 years than the other two groups (P=0.021and P=0.001) and the ratio of poor-risk karyotype higher in patients aged ≥ 60 years than in patients aged ≤30 years (P=0.046).Among 29 patients with acute lymphoblastic leukemia (ALL),10 cases had poor-risk and 19 cases had intermediate-risk karyotype.Conclusions Karyotype analysis provides an important basis for risk assessment and the rate of poor-risk karyotype may increase with the ageing in patients with AML.

Objective To explore the cytogenetic characteristics of acute myeloid leukemia(AML) patients.Methods The karyotype analysis was performed in 178 AML using the short-term culture of bone marrow cell and G-banding technique.Results Among the 178 patients,171 had enough metaphases for analysis and 128(74.9%)had clonal karyotypic abnormalities.Twenty-seven patients were secondary to myelodysplastic syndrome (MDS-AML),with 25 (92.6%) patients carrying clonal karyotypic abnormalities.Among the remaining 144 patients of de novo AML,103(71.5%)had clonal karyotypic abnormalities.The rate of abnormal clonal karyotype was higher in MDS-AML than that of de novo AML (P=0.021).Among the 171 patients,41(24.0%)were in favorable risk group,80(46.8%)in intermediate risk group and 50(29.2%)in adverse risk group.t(15;17)was the most common chromosomal aberration.The maiority intermediate risk chromosomal aberration was;normal karyotype.The most common cytogenetic abnormality among adverse group was a complex karyotype.Adverse cytogenetic aberrations,such as -5/5q-,-7/7q-,frequently occurred in conjunction with one another as part of a complex karyotype.Totally 75 patients were 60 years or older,among them,16.0%were in favorable risk group,48.0%in intermediate risk group and 36.0%in adverse risk group.Among 96 younger patients,30.2%were in favorable risk group.45.8%in intermediate risk group and 24.0%in adverse risk group.The rate of favorable risk chromosomal aberration was lower in elder patients than in younger(P=0.03 1).The rate of adverse risk chromosomal aberration and the rate of monosomal karyotype were higher in MDSAML than in de novo AML patients(P<0.001).Conclusions The most common favorable,intermediate and adverse chromosomal aberrations were t(15;17),normal karyotype and complex karyotype respectively.The karyotype was poor in MDS-AML and elder AML patients.

Objective To evaluate the effect of a modified culture method on the karyotype anomalies detection rate in elderly patients with multiple myeloma (MM),and to explore the relationship between clinical characteristics and chromosome anomalies in multiple myeloma.Methods Two culture methods were applied on the bone marrow samples which obtained from 28 MM patients.One method was used to culture cells for 24 hours with interleukin 6 (IL-6) 10 μg/L and granulocyte-macrophage colony-stimulating factor (GM-CSF) 40 μg/L,and the other for 6 days.Karyotype was analyzed by G-banding technique.Results In the 24-hour culture group,no metaphases cell was found in 4 cases (14.3 ％),karyotype anomalies were found in 6 cases in the other 24 cases,and the detection rate was 25.0％ (6/24).In the 6-day culture group,no metaphases cell was found in 1 patient (3.6％),karyotype anomalies were found in 15 cases in the other 27 patients,and the detection rate was 55.6％ (15/27).There was a significant difference in the detection rate of karyotype anomalies between the two groups (x2 =4.89,P ＜ 0.05).In 27 cases with enough metaphases in the 6-day culture group,20 cases were newly diagnosed or in progression,among whom karyotype anomalies were found in 14 cases (70.0％,14/20),and 7 cases were in stable phase,among whom karyotype anomalies were found in 1 case (14.3％,1/7).The detection rate of abnormal karyotype was higher in newly diagnosed or in progressive patients than in stable patients (P ＜0.05).Conclusions 6-day culture method can improve the detection rate of karyotype anomalies in elderly patients with multiple myeloma,which is better than 24-hour culture method.The detection rate of karyotype anomalies is higher in newly diagnosed or in progressive patients than in stable patients.

The growth changes of glutathione (GSH) and ergosterol in Saccharomyces cerevisiae (CICC1447 and CICC1339) were detected under 0.5Mpa pressure with compressed high-pure air (O-2∶N-2=21∶79). The results showed that logarithmic phases of the two strains were delayed; their biomass and special growth rate were lower than those of control sample (0.1MPa) and the double time were prolonged under 0.5MPa. High-pressure could increase the content of GSH obviously, compared to ambient atmosphere control samples. When the holding time was 3h, the content of GSH and ergosterol in CICC1447 increased 42.6% and 20.1%, respectively. However, the content of GSH in CICC1339 increased 58.7% when the holding time was 6h, while ergosterol content reduced. The results indicated that different yeast strains have different stress-response mechanism to copy with high-pressure shock.

[Summary] A case of primary hyperparathyroidism ( PHPT ) complicated with Graves′disease was reported.The parathyroid lesion( s) could not be identified by repeated MIBI and ultrasonography tests.With the control of hyperthyroidism, medical therapies of hypercalcemia were still not effective, the serum calcium levels continued to be high.Thus, the decision to operate was made.The pathological findings confirmed the diagnosis of parathyroid adenoma.For PHPT patients with clear surgical indications, even though the pre-operative localizing tests are negative, operation is still worth to try.

Objective To assess the early prognosis of 117 patients after carduopulmonary resuscitation (CPR) in ICU by using the markers of inflammation,Glasgow Coma Scale (GCS) and Acute Physiology and Chronic Health Evaluation Ⅱ (APACHE Ⅱ) scores.Methods A total of 117 CPR patients admitted between 2010 January to 2012 December were enrolled for study.Within 24 h after admission,inflammatory markers,blood routine items,hepatorenal function,electrolytes of blood were measured.The GCS and APACHE Ⅱ scores were recorded.Arterial blood gas analyses were performed at 0,12,and 24 h after hospitalization,and the 12-h and 24-h lactate clearance rates were calculated.Seven days after treatment,according to the outcomes,the patients were divided into survival group and death group,and the clinical data of two groups were analyzed.Results (1) Of them,73 patients died and 44 survived.Factor analysis showed that age,time elapsed from resuscitation to ICU admission,D-dimer,arterial oxygenation index (FiO2),arterial blood pH,arterial blood lactate concentration upon ICU admission,GCS score and APACHE Ⅱ score were significantly different between the two groups (P ＜ 0.05or P ＜ 0.01); (2) Two classification logistic regression analysis showed that D-Dimer,GCS score and APACHE Ⅱ score significantly correlated with the mortality risk of the patients in the wake of CPR with relative odds ratios of 1.000,2.091,and 0.531,respectively (P ＜ 0.05 or P ＜ 0.01) ; (3) Receiver operating characteristic curve analysis indicated that the area under the curve of GCS (0.821) and APACHE Ⅱ (0.869) had higher predictive value than D-dimer (0.655).The highest accuracy (84.6％) in predicting patient survival was achieved when the GCS score was 6.5.Meanwhile,the highest accuracy (82.1％) in predicting patient death was achieved when the APACHE Ⅱ score was 17.5.Conclusions Both GCS score and APACHE Ⅱ score has obvious correlation with the prognosis of the critically ill patients after CPR and could be used to predict prognosis at early stage.
