The authors studied the redistribution of the myocardial blood flow with radioactive biomicrospheres in dogs suffering from acute myocardial ischemia. After the left anterior descending coronary vessel was ligated, there was a great decrease in blood flow of the central ischemic zone. The blood flow of the zone near the border was greater than the central ischemic zone, and was less than the zone far from the border and the nonischemic zone. The endocardial blood flow of the central ischemic zone and the zone near the border became less than the epicardial blood flow (end./epi

Objective To evaluate the value of multiparametric MRI for prediction of prostate cancer pathology and tumor staging. Methods A total of 80 patients with prostate cancer admitted during the period from 2016 to 2021 were enrolled as the study subjects, and all patients underwent multiparametric MRI. The pathological examination of radical prostatectomy specimens was used as a gold standard to evaluate the predictive value of multiparametric MRI for significant prostate cancaer, extracapsular extension, index lesion location and lymph node metastasis. Results Multiparametric MRI showed a sensitive of 96%, specificity of 60%, positive predictive value of 97.3% and negative predictive value of 50% for prediction of significant prostate cancer, and the concordance between multiparametric MRI and pathology of radical prostatectomy specimens was 75% for prediction of index lesions. In addition, multiparametric MRI showed a 40% sensitivity, 91.4% specificity, 85.7% positive predictive value and 54.2% negative predictive value for identification of extracapsular extension and a 16.7% accuracy for detection of lymph node metastasis. Conclusion Multiparametric MRI is highly sensitive for predicting significant prostate cancer with a high positive predictive value and is highly accurate for identification of index lesions of prostate cancer, which is of great value to propose prostate cancer treatment schemes and evaluate the clinical prognosis among prostate cancer patients.

Objective To define the nuclear agrresome formation is determinated by which part of the UL76 of
HCMV. Full-length, conserved N terminal and unconserved C terminal of pUL76 were constructed to eukaryotic ex-pression plasmid pEGFP-N1 . Methods Primers were designed to amplify full-length and different part of pUL76 according to standard sequence of HCMV AD169 which had been submitted to GenBank(FJ527563. 1). These frag-ments were constructed to eukaryotic expression plasmid pEGFP-N1 . The recombinant plasmids were designated pEGFP-UL76,pEGFP-UL76N, pEGFP-UL76C respectively. Double digestion and sequencing were performed to verify the accuracy of recombinant plasmids construction. Empty vector and three recombinant plasmids were transi-ent transfected to HELF and HepG-2 cells respectively. Reverse transcriptation PCR and Western blot were per-formed to detect the RNA and protein expression level respectively. Different nuclear aggresome formations were visualized with an Olympus fluorescence microscopy. Results pEGFP-N1 and pEGFP-UL76N were unable to in-duce nuclear aggresome formation, whereas pEGFP-UL76 and pEGFP-UL76C were able to elicit nuclear aggresome formation. Conclusion The unconserved C terminal of pUL76 is sufficient to induce nuclear aggresome formation.

Objective To compare the effectiveness and safety of Foley catheter(FC)and vaginal prostaglandin E2 suppository(PGE2,Propess)for cervical ripening and labor induction in fullterm pregnant women with unfavorable cervix.Methods A prospective randomized controlled trial was conducted.Women with a term or post-term,live,singleton fetus in cephalic presentation,intact membranes,Bishop score＜6,not in labor,medically indicated for labor induction from June 2009 to December 2009 in Drum Tower Hospital of Nanjing University Medical School were randomly divided into two groups:FC group(n=64)and Propess group(n=62).In FC group,a 16-F Foley catheter was inserted into patient's cervical canal; once past the internal os,the balloon was inflated with 80 ml saline.Intravenous oxytocin was initiated after the balloon was spontaneously extruded from the cervix or after 24 hours.In Propess group,vaginal Propess was used.x2 or Fisher's exact test and t test were used to compare the outcomes,delivery mode and induction success rate between the two groups.Results There were no significant differences in gestational weeks,Bishop score,indication of induction,improvement of Bishop score,success rate of induction,rate of vaginal delivery,total duration of labor and volume of postpartum hemorrhage between the two groups(P ＞ 0.05,respectively).Propess group had a higher rate of vaginal birth within 24 hours[56.5％(35/62)vs 28.1％(18/64),t=10.37,P＜0.05],a higher risk for excessively frequent and hard uterine contraction[17.7％(11/62)vs 0.0％(0/64),P＜0.05]and lower incidence of oxytocin induction/augmentation during labor[21.0％(13/62)vs 87.5％(56/64),x2 =56.27,P＜0.05]than those of FC group.There were no differences in neonatal Apgar score,meconium staining and neonatal birth weight between the two groups.Puerperal infection occured in neither group.Conclusions Under strict control of indication and aseptic manipulation,Foley catheter was as effective and safe as Propess for cervical ripening with lower risk of excessive uterine activity.It is suggested that Foley catheter could be used for cervical ripening,especially in patients with economic difficulty.

Objective To explore the clinical value of serum interleukin(IL)-33 and its soluble receptor ST2(sST2) level in patients with chronic hepatitis B.Methods A total of 65 cases with chronic hepatitis B were recruited into study group,meanwhile 60 healthy persons were enrolled in the control group from January 2014 to October 2016 in our hospital.IL-33,sST2 and alanine aminotransferase(ALT) were detected and compared in the two groups.Results The level of IL-33,sST2 and ALT were significant higher than those of the control group(t=6.542,7.218,6.324;P<0.05).IL-33 and sST2 levels in chronic hepatitis B patients with abnormal ALT level were significant higher than those with normal ALT(t=16.328,9.874,P<0.05).Conclusion The detection of IL-33 and sST2 in patients with chronic hepatitis B could help to understand the immune status of patients,and provide a theoretical basis for the treatment of chronic hepatitis B.

AIM: To explore the characteristics of T cell activation and regulatory T cells derived from murine Peyer's patches through comparative studies on Peyer's patches, mesenteric lymph nodes and inguinal lymph nodes. METHODS: Signal cell suspendsions were prepared from murine mesenteric lymph nodes (MLNs), the Peyer's patches (PPs) and inguinal lymph nodes (ILNs), respectively. The percentage of cell subpopulations such as CD3+ T cells, CD3+CD4+ helper T cells and regulatory T cells (Treg, CD4+CD25+) were analyzed. Lymphocytes were activated by polyclonal stimulators such as concanavalin (Con A), phorbol 12, 13-dibutyrate (PDB) only, and PDB plus ionomycin (Ion). The expression of CD69 (the early marker of CD3+ T cell activation) was measured by FACS. RESULTS: A lower ratio of CD3+ T cells was seen in PPs than those in MLNs and ILNs. The ratios of CD3+ CD4+ T cells to CD3+ T cells in PPs, MLNs and ILNs were almost the same. A higher rate of Treg was seen in CD4+ T cells from the PPs as compared with those from MLNs and ILNs. A higher percentage of activated CD3+ T cells derived from the PPs cultured without polyclonal stimulators were detected as compared to MLNs and ILNs, while lower responsiveness of CD3+ T cells from the PPs stimulated by Con A was seen as compared with those from MLNs and ILNs. CONCLUSIONS: The lower rate of CD3+ T cells as well as higher rate of Treg in PPs was due to its desensitization. The higher rate of basic activated state in CD3+ T cells from the PPs indicated that the T cells were activated by enteric antigens in physiological conditions. The lower responsiveness of activation to some polyclonal stimulators probably reveals that the T cells are in a state of anergy. All the characteristics mentioned above contribute to prevent pathological inflammations and maintain tolerance to enteric antigens such as food proteins and commensal bacteria but simultaneously retain proper immune responses to pathogenic microbes.

Objective To determine the degree of damage to hairs by Geotrichum, and to compare the difference in infection duration and intensity by Geotrichum silvicola isolates from skin lesions and blood and Geotrichum candidumn isolates between hairs from different age groups. Methods In vitro hair perforation test was carried out on the hairs from healthy individuals of different age groups. Scanning electron microscopy was performed to observe hairs perforated by Geotrichum silvicola isolates from skin lesions and blood as well as Geotrichum candidumn isolates. Results Both Geotrichum silvicola and Geotrichum candidumn isolates could perforate hairs. The time taken to perorate hairs was significantly different between isolates of Geotrichum silvicola from skin lesions, blood and Geotrichum candidumn in every age groups (all P ＜ 0.05).The Geotrichum silvicola isolates from blood perforated hairs in the shortest time (range: 53 - 64 days, mean:58.07 ± 3.15 days), followed by those from skin lesions (range: 57 - 66 days, mean: 61.05 ± 2.55 days), and Geotrichum candidumn (range: 61 - 74 days, mean: 67.11 ± 3.78 days). The time taken to perforate hairs by Geotrichum significantly increased with age, and significant difference was observed between hairs from the four age groups, i.e., ＜ 2 years, 2 - 13 years, 14 - 19 yeas, ＞ 19 years, but not between the age group of ＜ 2 years and that of 2 - 13 years (P ＞ 0.05 ). As scanning electron microscopy showed, both Geotrichum silvicola and Geotrichum candidumn could damage hairs, and the degree of damage by Geotrichum silvicola was more severe than that by Geotrichum candidumn. Conclusions The damage to hairs by Geotrichum silvicola is earlier and more severe than that by Geotrichum candidumn. The younger the age, the more liable the hairs to be damaged by Geotrichum.
