Objective To explore the relationship between the levels of plasma coagulation factors (F) and acute myocardial infarction (AMI) in low age period (<60 years old) and their diagnostic value in diagnosing AMI in low age period.Methods One hundred and sixty inpatients with low age AMI in the cardiology department of the Heze Municipal Hospital were selected as the case group,and contemporaneous 160 cases of low age non-AMI served as the control group.F Ⅱ,FⅦ,FⅧ,fibrinogen (Fg) and von willebrand (vWF) were measured with enzyme-linked immunoabsorbent anti-sandwich assay.The relationship between coagulation factors and low age AMI was analyzed with univariate and multivariate analysis,and their value for diagnosing low age AMI was evaluated with diagnostic test and receiver operating characteristics (ROC) curve.Results The univariate analysis showed that FⅡ,FⅦ,FⅧ and Fg levels had significantly statistical difference between the case group and control group(P<0.05),and the vWF level had no statistically difference(P>0.05).The multivariate analysis indicated that the FⅡ level≥ 14.27 μg/L and FⅦ level ≥22.99 μg/L were the independent risk factors for low age AMI.The value of FⅡ for diagnosing low age AMI was lower,and the optimal cut off value of Fg for diagnosing low age AMI was 22.99 μg/L,its area under ROC curve was 0.709 with a moderate diagnostic value,and the sensitivity (91.88%) and negative predictive value (86.02%) were higher,the false negative rate (13.98%) was lower,and the accuracy (70.94%) was moderate.Conclusion The FⅡ level ≥14.27 μg/L and Fg level ≥22.99 μg/L are the independent risk factors for low age AMI,and detecting the Fg level could have hint significance in diagnosing low age AMI.

BACKGROUND: There are disputes concerning limb salvage and reconstruction in treating pelvis malignant tumor.OBJECTIVE: To study the surgical treatment following resection of tumor at acetabular region in order to restore pelvic stability with less damage or recurrence.METHODS: Thirty-three patients diagnosed with pelvic tumor at Department of Orthopaedics, First Affiliated Hospital of Second Military Medical University from April 2002 to June 2008 were selected. All patients were received tumor resection and computer-aided prosthetic replacement, 18 patients (8 cases with chondrosarcoma, 2 cases with Ewing sarcoma, 2 cases with osteosarcoma, and 6 cases with malignant fibrous histiocytoma) were combined with antitumor drug treatment. Functional assessment of therapeutic efficacy was divided into 4 levels: excellent, good, moderate, and inferior.RESULTS AND CONCLUSION: Two patients died at months 4 and 6 after prosthetic replacement; 31 cases were followed-up for 8-32 months, mean 12.5 months. Seven cases were recurred chondrosarcoma, the recovery of other patients were as follow: 18 cases were excellent, 4 cases were good, 2 cases were moderate and no case was inferior. Most of limb function and pelvic stability was preserved. The results suggested that malignant fibrous histiocytoma and Ewing sarcoma can receive a high rate of limb preservation if treated by effective chemotherapy with low recurrence; the recurrence of chondrosarcoma was high. Tumor resection combined with computer-aided prosthetic replacement can maximatily reserve limb function and raise life quality.

Objective To investigate the expression and clinicopathological significance of CXCR4 and HIF-1α protein in esophageal squamous cell carcinoma tissue and explore their correlation.Methods The expression of CXCR4 and HIF-1α protein were assessed by immunohistochemistry SP method in 56 cases with esophageal squamous cell carcinoma and in 20 cases with surrounded normal tissue.Results The expressions of CXCR4 and HIF-lα in esophageal squamous cell carcinoma were significantly higher than those in normal tissues[62.50 ％ (35/56) vs 10.00 ％ (2/20); 57.14 ％ (32/56) vs 0(0/20)](x2=16.259,19.740,P ＜0.01).The expression of CXCR4 and HIF-1α were both correlated with invasion depth (x2 =4.736,7.665,P ＜0.05) and lymph node metastasis ( x2 =7.207,6.389,P ＜0.05),and had no correlation with cancer cell differentiation.The expressions of CXCR4 and HIF-lα in esophageal squamous cell carcinoma were positively correlated (r =0.298,P ＜0.05).Conclusion CXCR4 and HIF-1α are highly expressed in esophageal squamous cell carcinoma.The two have a close relation to esophageal squamous cell carcinoma growth,invasion and metastasis.

OBJECTIVETo evaluate effectiveness therapeutic regimens for obstructive sleep apnea hypopnea syndrome (OSAHS) children at an acceptable cost.

METHODThis study was performed at Yuying Children's Hospital of Wenzhou Medical University from Mar. 2008 to Dec. 2010. Prospective random number table method was used for the analysis; 60 children with mild OSAHS were divided into Mild OSAHS Montelukast Treatment (MM) group and Mild OSAHS Adenotonsillectomy Treatment (MAT) group. 32 children in MM group were treated with leukotriene receptor antagonists (LTRAs), while 28 children in MAT group were treated with adenotonsillectomy. Also, 58 children with moderate and severe OSAHS were divided into severe OSAHS Montelukast Treatment (SM) group and severe OSAHS Adenotonsillectomy Treatmen (SAT) group. Twenty-two children in SM group were treated with LTRAs, while 36 children in SAT group were treated with adenotonsillectomy. All selected children were evaluated by polysomnography (PSG) and Obstructive Sleep Apnea-18 (OSA-18) items before and after a six-month treatment. Both records were taken and analyzed, surgical complications and the reason for non-remission after operation were also analyzed. Two therapies were compared based on economic consideration and therapeutic effect. Result (1) PSG: A significant change of a significant change of Apnea Hypopnea Index (AHI) was observed in MM group after the treatment (before receiving the treatment 4.56 ± 1. 26, and after receiving the treatment 3. 48 ± 1. 52, t =3. 50, P <0. 05). But for oxygen desaturation Index (ODI) (MM group 2. 18 ± 2. 19, and MAT group 1. 80 ± 2. 34) and Lowest Oxygen satuation (LSaO2) (MM group 91. 66 ± 2. 34, and MAT group 92. 79 ± 2. 18), there was no significant difference in MM group and MAT group after the treatment (ODI, t =0. 65, and LSaO2 t = - 1. 93, P >0. 05). (2) OSA-18 scores: Significant differences were found in sleeping disorder (before 14. 81 ± 6. 28, and after 10. 56 ± 3. 57), the degree of familial stress (before 13. 56 ± 3. 54, and after 8. 97 ± 2. 96), and OSA-18 total scores (before 52. 66 ± 1. 11, and after 42. 56 6. 48) in MM group after the treatment (sleeping disorder Z - 3. 14, the degree of familial stress Z = -4. 50, and OSA-18 total scores Z= -4. 01, P <0. 05). (3) In addition to the cost of drugs, groups with surgical treatment had a larger economic burden than those with LTRAs treatment. (4) Treatment was totally effective for 28 children (88%) in MM group, and 28 children (100%) in MAT group. Meanwhile, treatment also achieved an obvious effect on 2 children (9%) in SM group, and in 35 children (97%) in SAT group. In MAT group, 3 children improved (11%). And in SAT group, 7 children improved (19%), but treatment was found to be ineffective in 1 case (3%). Among those effective and ineffective cases in groups with surgical treatment, there were 9 children with nasal diseases.

CONCLUSION(1) Surgical treatment is recommended as the first choice for children with moderate and severe OSAHS. And for those who also suffer from nasal diseases, treatment combining drugs with surgery is necessary. (2) LTRAs therapy has a good effect for mild OSAHS. Surgery is also recommended when drugs could not achieve any obvious improvement in clinical symptoms of children with mild OSAHS.

Objective To investigate the effects of family allergic history and dermatophagoides farina on the expressions of Th1/Th2 cytokine of cord blood and allergic disorders in infancy.Methods Ten mil cord blood were obtained from 34 neonates which 17 cases had family allergic history and 17 cases didn′t have.Cord blood mononuclear cells(CBMC) were isolated by gradient centrifugation with Ficoll and were cultured with phytohemagglutinin(PHA) or dermatophagoides farina for 48 hours in vitro.The expressions of interleukin(IL-4) and interferon(IFN-?) of the culture supernatant were detected by enzyme-linked immunosorbent assay(ELISA).Two groups were visited with telephone or clinical service every 1 or 2 months in 1 year follow-up survey.Results In no stimulation,the expressions of IL-4 of family allergic history and no family allergic history were(11.35?1.80) ng/L and(11.0?1.50) ng/L,respectively,there was no significant difference.The expressions of IFN-? were(9.55?1.47) ng/L and(10.19?1.37) ng/L,respectively,there was no significant difference also.In PHA stimulation,the expressions of IL-4 were(43.45?4.57) ng/L and(37.58?3.41) ng/L,respectively,there was significant difference.The expressions of IFN-? were(72.61?25.40) ng/L and(65.84?29.96) ng/L,respectively,there was no significant diffe-rence.In low density dermatophagoides farina stimulation,the expressions of IL-4 were(40.54?3.64) ng/L and(37.17?2.60) ng/L,respectively,which had significant difference.The expressions of IFN-? were(35.30?2.73) ng/L and(40.55?1.85) ng/L,respectively,which had significant difference.In high density dermatophagoides farina stimulation,the expressions of IL-4 were(43.50?3.19) ng/L and(39.55?4.13) ng/L,respectively,which had significant difference.The expressions of IFN-? were(39.40 ?5.21) ng/L and(40.94?2.96) ng/L respectively,which had no significant difference.Allergic diseases were happened in 7 cases of 13 cases with family allergic history and in 2 cases of 15 cases without family allergic history in 1 year follow-up except lost follow-up cases.There were significant difference in 2 groups.Conclusions Th2 cells of cord blood are relative dominant in neonates having family allergic history.Th2 cells relative dominant are more obvious in dermatophagoides farina stimulation.The neonates having family allergic history have a tendency to get allergic diseases in childhood.

Objective To explore a method for isolation and culture of human epidermal stem cells. Methods Epidermis was obtained by digesting human foreskin with Dispase Ⅱ and Trypsin-EDTA.After suspension on the epidermal stem cell medium (ESCM), these single epidermis cells were inoculated onto human collagen Ⅳ-coated flasks and cultured at 37 ℃ in a humidified atmosphere containing 5% CO_2 for 10 min. The nonadherent cells were rinsed off 10 min after inoculation, and the adherent cells continued to be cultured after enriching and abstraction by type Ⅳ collagen. The cell growth was observed through inverted microscope, and the cell cloning efficiency and time of clone sustain were also detected. Immunocytochemistry was used to observe the expression of ?_1-integrin and keratin 19(K19). Keratinocytes were served as controls. Results It was revealed by histological observation that colonies were formed 24 hours after inoculation. The isolated and cultured cell cloning efficiency was higher and the time of clone sustain was longer than that of the control group. Positive expression of ?_1-integrin and K19 of cultured cells was detected by immunocytochemistry. Conclusion Adult epidermal stem cells could be successfully isolated and cultured by adhension with type Ⅳ collagen and culture with ESCM.
