Objective: To explore the myocardial protection of induction and reperfusion with warm blood cardioplegia for hypoxic immature myocardium. Methods: A hypoxic model of neonatal rabbits was established in this study. Some indexes,such as myocardial energy metabolism, water content, SOD, MDA and myocardial ultrastucture, were observed after induction and reperfusion with warm blood cardioplegia, comparing to cold crystalloid cardioplegia. Results: Hypoxic neonatal rabbits in this study presented cyanotis, hypoxemia and higher ratio of RV/(LV+S) simulating the pathophysiological changes in cyanotic congenital heart disease. It could be built and repeated easily in experimental researches of immature myocardial protection. Myocardial ATP content was (13.09?1.50) ?mol/g in studying group versus (11.53?5.40)?mol/g in control group (P

Objective To assess the blood safety under the current sero-screening program and gain experience on how to implement NAT as a routine assay for blood screening in China. Methods Sera from 103,539 non-remunerated donors of Shanghai blood center were tested by Chiron's Procleix(TMA HIV-1/HCV Assay in 2 study stages with 8 and 24 sample-pool respectively. Results 5 NAT positive samples were found to be Anti-HCV EIA-2 test positive at the same time. No window period cases of HIV-1/HCV were found in this donor group. But 275 (0.27% ) anti-HCV and 107 (0. 10%) anti-HIV false positive samples were identified by the second sero-screening. Conclusion The blood quality of Shanghai city was high to be close to the level of developed countries and the window period risk of HIV-1 and HCV was less than 1:100,000. With its high sensitivity and specificity,Procleix( TMA HIV-1/HCV Assay can be used in routine blood screening in China.

Objective:To investigate the high risk factors of pelvic lymph node metastasis in patients with type Ⅰ endometrial carcinoma in order to provide the basis for making reasonable operation scope.Methods:Risk factors of pelvic lymph node metastasis were analyzed in 136 cases of type Ⅰ endometrial carcinoma.Univariate analysis was performed with Chi square test or Fisher's exact probability method,and multivariate analysis was performed with a logistic regression mode.Results:The positive rate of pelvic lymph nodes in 136 patients with type Ⅰ endometrial carcinoma was 9.56％ (13/136).Univariate analysis showed that histological grade,size of lesion,depth of myometrial invasion and vascular invasion were related to lymph node metastasis(P ＜0.05);Multivariate Logistic analysis showed that low differentiation,deep muscular invasion,tumor diameter≥2 cm and LVSI were independent risk factors of pelvic lymph node metastasis in patients with type Ⅰ endometrial carcinoma(P ＜0.05).Conclusions:The rate of pelvic lymph node metastasis is low in type Ⅰ endometrial carcinoma.Patients with low differentiation,deep muscular invasion,tumor diameter≥2 cm and LVSI are more likely to occur pelvic lymph node metastasis in type Ⅰ endometrial carcinoma.

Our previous study demonstrated that human KIAA0100 gene is a novel acute monocytic leukemia-associated antigen (MLAA) gene. But the functional characterization of human KIAA0100 gene has remained unknown to date. Here, firstly, bioinformatic prediction of human KIAA0100 gene was carried out using online software;Secondly, human KIAA0100 gene expression was downregulated by the clustered regularly interspaced short palindromic repeats (CRISPR)/CRISPR-associated (Cas) 9 system in U937 cells. Cell proliferation and apoptosis were next evaluated in KIAA0100-knockdown U937 cells. The bioinformatic prediction showed that human KIAA0100 gene was located on 17q11.2, and human KIAA0100 protein was located in the secretory pathway. Besides, human KIAA0100 protein contained a signal peptide, a transmembrane region, three types of secondary structures (alpha helix, extended strand, and random coil) , and four domains from mitochondrial protein 27 (FMP27). The observation on functional characterization of human KIAA0100 gene revealed that its downregulation inhibited cell proliferation, and promoted cell apoptosis in U937 cells. To summarize, these results suggest human KIAA0100 gene possibly comes within mitochondrial genome; moreover, it is a novel anti-apoptotic factor related to carcinogenesis or progression in acute monocytic leukemia, and may be a potential target for immunotherapy against acute monocytic leukemia.

Monoclonal antibodies (MAbs) are important tools for the study of proteins′ function and structure. But there has been no report on the preparation of MAbs against human KIAA0100 protein up to date. Here, first, we generated the mouse MAb against human KIAA0100 protein using purified recombinant 6×Histidinc (6×His)- tagged human KIAA0100 protein segment (1557–2234) as an antigen; then, the mRNA expression of human KIAA0100 gene was detected in U937 cells using Northern blot analysis. The results showed that the mouse MAb against human KIAA0100 protein could sensitively recognize the human KIAA0100 protein using Western blot analysis and immunocytochemistry analysis. Besides, Western blot analysis revealed that human KIAA0100 gene possibly encoded two different protein products (254 kDa and < 250 kDa) in U937 cells. Moreover, Northern blot analysis confirmed that human KIAA0100 gene might produced two different mRNA products (6000–10000 bp and 5000–6000 bp) in U937 cells. The results provide a basis for large-scale production of the MAb against human KIAA0100 protein, which will be useful for the study of human KIAA0100 protein′s function/structure and MAb-targeted drugs in the future.

OBJECTIVETo investigate the effect and safety of extracorporeal shock wave (ESW) in the treatment of pain symptom of type III B prostatitis.

METHODSWe treated 50 cases of type III B prostatitis by ESW once a week for 4 weeks. Then we evaluated the clinical effect and safety of the therapy based on the NIH-CPSI scores, visual analogue scale (VAS) scores, IIEF-5 scores, prostate volume and morphous, state of urination, color of urine, results of routine semen analysis, and changes of cytokines (IL-6, TNF-α and IL-1β) in expressed prostatic secretion (EPS).

RESULTSAll the patients successfully accomplished the treatment. Compared with the baseline, decreases were observed after 4 weeks of cytokine treatment in the pain scores (14. 61 ± 1. 82 vs 9. 36 ± 1. 47, P <0. 01), urination symptom scores (4. 59 ± 1. 01 vs.4. 66 ± 0. 89, P >0. 05) , quality of life scores (6. 51 ± 1. 03 vs 4. 56 ± 1. 02, P <0. 01), NIH-CPSI (25. 43 ± 1. 72 vs 18. 28 ± 2. 32, P <0. 01 ), and VAS (6. 59 ± 1. 10 vs 3. 02 ± 1. 07, P < 0. 01). The concentration of IL-6 in the EPS was significantly increased ([55.82 ± 6. 28] vs [86.59 ± 4. 55] ng/ml, P <0. 01) , while the level of TNF-α ([3.89 ± 0. 12] vs [3. 19 ± 0.22] ng/ml, P<0.01) and that of IL-1β ([3.21 ± 1.01] vs [1.48 ± 0.95] ng/ml, P< 0. 01) remarkably reduced after treatment. However, there were no statistically significant differences in IIEF-5 scores (18. 58 ± 2. 03 vs 18. 51 1. 89, P >0. 05) or various sperm parameters before and after treatment (P >0. 05). And no significant changes were observed in the prostate volume, morphous or internal echoes.

CONCLUSIONThe ESW therapy is effective and safe for the pain symptom of type III B prostatitis.

Objective To investigate the effects of icariin, a major active component of traditional Chinese herb Epimedium on schizo-phrenia animal model. Methods MK-801, a N-methyl-D-aspartate (NMDA) receptor antagonist, was intraperitoneally injected into mice to establish a schizophrenia animal model. The open field behavior test infrared detection system was used to measure the mobility of mice in order to find the best optimal dose. 40 mice were randomly divided in to control group, model group, risperidone group and icariin group with 10 mice in each group. The risperidone group and the icariin group were given 0.1 mg/kg risperidone and 50 mg/kg icariin respectively. All groups were injected with 0.6 mg/kg MK-801 0.1 ml intraperitoneally, except the control group. The total distance and the central dis-tance within 210 minutes were tested. Results The total distance and the central distance were significantly longer in the model group than in the control group (P<0.001), and were shorter in the risperidone group than in the control group (P<0.05). The total distance was shorter in the icariin group than in the model group, but there was no significant difference (P=0.065); and the central distance was shorter (P=0.037). There was no significant difference in both total distance and the central distance between the risperidone group and the icariin group (P>0.05). Conclusion Icariin may improve the positive and negative symptoms of schizophrenia mice, which may be beneficial to schizo-phrenia therapy.
