ObjectiveThe difference of Cys-C ( serum cysteine proteinase inhibitor C) among sepsis group,systemic inflammatory response syndrome (SIRS) group,and non -SIRS group were explored in this study.The significance of mortality and the relationship between Cys-C and acute physiology and chronic health evaluation (APACHE)Ⅱ score were under discussed. Methods After excluding the individual whose survival less than 24 hours,two hundred and fifty patients sought medical care in the emergency department of Beijing Chaoyang Hospital of the Capital Medical University were selected as samples from October 2008 to October 2009.They were classified into three groups:SIRS group ( n =121 ),non-SIRS group (n =74) and sepsis group ( n =55 ).The serum Cys-C level and APACHE Ⅱ score were determined for each patient.The positive detection rate of Cys-C ( ＞ 830 ng/ml) was calculated and then a 28-day mortality was recorded according to this study result.The positive detection rate and 28-day mortality were also compared with chi-square test.The prognostic values of Cys-C,APACHE Ⅱ score for the 28-daymortality were evaluated by logistic regression analysis.Results There was significant change observed between sepsis group and non-SIRS group (41.38％ vs. 13.57％,P =0.007 ) for the positive detection rate of Cys-C,as well as that between SIRS group and non-SIRS group ( 32.79％ vs. 13.57％,P =0.005).However,a contrary result was obtained when compared sepsis group with SIRS group (41.38％ vs.32.79％,P =0.346) ).Significant difference was noticed in the 28-day mortality of the patients from sepsis group and SIRS group in comparison to those of non-SIRS group (41.6％ vs. 17.2％,P ＜ 0.01 ;36.91％ vs. 17.2％,P ＜ 0.05).Cys-C level in patient with sepsis indicated a positive correlation to APACHE Ⅱ score ( P ＜0.0001 ).ConclusionsThe positive rate of Cys-C in SIRS group and septic group were significantly higher than that of non-SIRS patients,and this is an index for poor prognosis in sepsis patients.

Objective To evaluate acoustic effects of laryngeal microsurgery on vocal polyp, vocal cyst and vocal leuko- plakia. Methods 300 cases in vocal fold diseases were measured acoustically pre - and post - microsurgery. Results After openation, jitter, shimmer and NNE decreased statistically in vocal polyp and vocal cyst patients, and did not improve in vocal leukoplakia patients. Whether or not the surgery was done, F0 of all patients did not change Conclusion Laryngeal microsurgery had definite effect on clearing benign focus. After surgery, vocal functioin improved in vocal polyp and cyst patients, and in vocal leukoplakia, there was no improvement in such a short time as one week.

ObjectiveTo assess the significance of serum cysteine proteinase inhibitor C (Cys-C) and β2 microglobulin (β2MG) concentrations in the diagnosis and prognosis of sepsis-induced acute kidney injury.Methods Two hundred and fifty patients presenting to the Emergency Department of Beijing Chaoyang Hospital from October 2008 to October 2009 with sepsis were assessed.Serum creatinine (SCr),β2MG and Cys-C concentrations and Acute Physiology and Chronic Health Evaluation Ⅱ ( APACHE Ⅱ ) scores were determined when the septic patients presented to the hospital. The 28-day mortality was recorded.The study patients were retrospectively divided into acute kidney injury ( n =63 ) and no acute kidney injury groups (n =187 ).The predictive accuracies of Cys-C and β2MG for acute kidney injury were analyzed by plotting a relative operating characteristic (ROC) curve.The Spearman interclass correlation method was used to analyze the correlation between Cys-C concentration and APACHE Ⅱ score in sepsisinduced acute kidney injury.ResultsCys-C and β2 MG concentrations were significantly greater in the acute than in the no acute kidney injury group [ ( 1189 ± 214) μg/L vs.(678 ± 118) μg/L,P =0.007 ; (3705 ±599)μg/L vs.(2365 ±446) μg/L,P =0.004,respectively].SCr concentrations and APACHE Ⅱ scores were significantly greater in the acute than in the no acute kidney injury group [ (145 ±49) vs.(73 ±25),P=0.013,(19 ±4) vs.(13 ±4),P=0.016].There was a significant correlation between Cys-C concentration and APACHEII score in the acute kidney injury group (P ＜0.01).The 28-day mortality was significantly greater in the acute than in the no acute kidney injury group.The areas under the ROC curve for Cys-C and β2MG concentrations were 0.909 ( OR =1.006,95％ CI =1.002 - 1.009) and 0.82 ( OR =1.001,95％ CI =1.000 -1.001),respectively.ConclusionsMonitoring of Cys-C and β2MG concentrations can effectively predict the occurrence of acute kidney injury in septic patients.Cys-C concentration is a more accurate predictor of this diagnosis than β2MG concentration.An increasing Cys-C concentration is an indicator of poor prognosis.

[Objective]To explore the result of total hip arthroplasty(THA) performed in patients with osteoarthritis secondary to developmental dysplasia of the hip(DDH) and the degree of hip dysplasia on the treatment result. [Method]Forty-seven cases(55 hips) with osteoarthritis secondary to DDH were treated with THA.According to the classification of Crowe,23 hips were in classⅠ,19 in classⅡand 13 in class Ⅲ/Ⅳ.Before operation,the morphological changes of acetabula and femurs were evaluated with helical CT.During the operation,the acetabula were reconstructed at the level of real acetabula,the femoral canal was carefully enlarged and the small and straight femoral protheses were employed.The Harris hip score was conducted in each patients preoperatively and postoperatively.[Result]The Harris hip score in class Ⅰ,Ⅱand Ⅲ/Ⅳ were from 50.7?7.6,44.9?6.2 and 41.1?8.2 preoperative to 90.6?3.7,87.3?4.5 and 82.7?7.3 postoperative,respectively.There was significant difference between them(P

Objective To investigate the impacts of long cold ischemic preservation time on the ultrastructural changes of donor heart and to provide the data for expanding the heart donor pool. Methods Heart was obtained from brain dead donor and preserved in the the University of Wisconsin (UW) solution at 4℃. Cardiac tissues were harvested at different time points of cold ischemic preservation (6, 8, 10, 12, 14 h) and observed under electron miscroscope. Results Donor heart did not have significant pathologied and ultrastructural changes when cold ischemic preservation time was 6 h. After that, time related impairment of myocardia and endothelium of coronary artery was seen.When ischemic time was longer than 12 h, focal myocardial necrosis and complete loss of the endothelium were detected. Conclusions Myocardial ultrastructure is an important index to evaluate the donor heart quality. Heart, which underwent 10 h of cold ischemia preservation time, causes no significant irreversible and pathological ultrastructural changes, and could be used for heart transplantation. When ischemia time was over 10 h, the donor heart presented with irreversible change and was nolonger unsuitable for transplantation.

BACKGROUND: Compared with the bone marrow mesenchymal stem cells, umbilical cord blood mesenchymal stem cells (UCB-MSCs) is an ideal source of tissue engineered seed cells, but the culture success rate is low.OBJECTIVE: To explore establish a stable reliable method to isolate and culture UCB-MSCs by optimizing medium choice,centrifugation speed and time, incubation density, choice of growth factor, first time of medium change.DESIGN, TIME AND SETTING: The cytological in vitro study was performed at the Department of Blood Transfusion, Bethune International Peace Hospital of Chinese PLA from January to October 2008.MATERIALS: A total of 20 samples of neonatal UCB by full-term uterine-incision delivery were supplied by Stem Cell Center,Bethune International Peace Hospital of Chinese PLA. Parturient and their family member signed the informed consent.METHODS: Under sterile conditions, UCB-MSCs were isolated by combination of density gradient centrifugation (1 500 r/min, totally 15 minutes) and different adherent time method. UCB-MSCs were incubated in DMEM/F12 medium, supplemented with 10% human UCB serum, 5 μg/L granulocyte-macrophage colony-stimulating factor (GM-CSF), 15 pg/L interleukin-3. MSCs at 1 ×1010/L were incubated in plastic flask coated with human UCB serum at 37℃ and 5% CO2 saturated humidity. The medium was changed following 3 days of culture. Non-adhered cells were removed. Subsequently, the medium was changed once every other 24 hours. When 80% confluence, UCB-MSCs were digested by the mixture of pancreatin-athylenediamine tetraacatic acid.MAIN OUTCOME MEASURES: Morphological changes of UCB-MSCs were observed by inverted phase contrast microscopy. Cell immunophenotypes were determined by flow cytometry.RESULTS: A small quantity of adherent round cells were determined after 24 hours, and adherent cells became more at 48 hours,with a few monopole spindle cells. Cell colonies were detected at day 7. Fibroblast-like cells arranged parallelly, presented whirlpool-shape and unclear boundary, with 80% 80% confluence 2-3 weeks following culture. At the second passage, these calls adhered at hour 12, and reached 80% 90% confluence at day 10. Flow cytometry showed that these calls were positive for CD29 and CD44, but negative for hematopoietic lineage marker CD34.CONCLUSION: MSCs can be successfully isolated from human UCB by using this modified method in vitro, with short culture cycle and high cell purification. Adherent cells have the same immunophenotype as bone marrow mesenchymal stem cells.

Objective To investigate the changes of serum inflammatory factors and blood glucose in patients with systemic inflammatory response syndrome (SIRS) . Methods Seventy eight SIRS patients were divided into survival subgroup (n =37) and fatal subgroup ( n = 41), 35 non-SIRS patients were designated as control group. Thirty eight out 76 patients whose blood glucose was higher than 6. 1 mmol/L were randomly selected for intensive insulin therapy. Serum IL-6, IL-10, IL-13, TNF-α and blood glucose were measured; HLA-DR expression on monocytes was detected. Results Serum IL-6, TNF-αand blood glucose levels were (80±8) vs. (42±7)×10~3μg/L, (52±20) vs. (17±6) ×10~3μg/L and (11.9±1.1)vs.(6.5±1.5)mmoL/L in SIRS vs.non-SIRS group respectively(all P＜0.05);those were(108±21)vs.(66±22)×10~3μg/L,(28±8)vs.(16±9)×10~3μg/L,(14.4±2.1)vs.(7.0±1.0)mmol/L in fatal vs.survival group,respectively(all P＜0.05).The changes of IL-10,IL-13 and HLA-DR expression intensity of monocyte showed a reverse trend.The intensive insulin therapy reversed the above tendency and reduced the fatality rate.Conclusions Blood glucose levels are corrected with serum cytokines in SIRS patients and reflex the immune status and disease prognosis.Intensive insulin therapy can improve the prognosis of SIRS patients.
