Objective To explore the clinical value of 99Tcm-MIBI G-MPI in patients diagnosed with myocardial bridging(MB) by CTA. Methods Forty-five patients with MB and 17 normal controls diagnosed by CTA(64 slices CT) were included. All patients underwent rest 99Tcm-MIBI G-MPI and 17 MB patients and 9 normal controls also underwent stress 99Tcm-MIBI G-MPI. Myocardial ischemia, function and wall motion were assessed. G-MPI results were compared with CTA results by χ2 test, Fisher exact test and t test. Results In patients with MB, the positive rate of abnormal perfusion by gated stress 99Tcm-MIBI G-MPI was 64.7% (11/17) and 41.2% (7/17) using quantitative analysis and visual evaluation respectively; while the data were 42.2% (19/45) and 22.2% (10/45) by rest G-MPI (P=0.035). The positive rate by rest G-MPI in MB patients was significant different among mural coronary arteries of different depths and different locations. By quantitative analysis of the stress G-MPI, the reversible, fixed, and mixed ischemia patients were 4 (35.3%), 6 (23.5%) and 1 (5.9%) respectively; the reversed, reversible and fixed abnormity of wall motion was found in 4 (23.5%), 4 (23.5%) and 2 (11.8%) patients respectively; the reversed, reversible and fixed wall thickening were found in 6 (35.3%), 5 (29.4%) and 1 (5.9%) patients respectively. There was no significant difference in left ventricular ejection fraction and peak filling rate between MB patients and normal controls in both rest and stress studies (t: from -0.564 to 1.292, all P>0.05). Conclusion The G-MPI may be useful for the evaluation of myocardial ischemia and myocardial function simultaneously in patients with MB.

OBJECTIVETo explore the clinical and pathological features of liver injury in adults with acquired rubella.

METHODSThirty-six adult patients with acquired rubella (AAR) were enrolled in this study, the liver functions were dynamically analyzed, liver biopsy was done in two patients.

RESULTSLiver injury was found in 77.8% of the 36 patients, with slight elevation of ALT and/or AST. The highest incidence and the most serious liver injury occurred in the period of 6-10d after vanishing of the rashes. Viral inclusion bodies were found in the liver specimen, with complete histological architecture but slight inflammation. The mean hospitalization days of AAR accompanied with liver injury and without liver injury were 18.2 days, 7.8 days, respectively (u=3.596>1.96, P<0.05).

CONCLUSIONHigh incidence of liver injury is observed in the adult patients with acquired rubella occurred in recent years, usually exhibited by mild liver injury with slight elevation of ALT. The elevation of AST or jaundice may indicate more serious liver injury, and these patients should be given active treatment to prevent acute liver failure. Liver injury may prolong the course of rubella patients.

OBJECTIVEThe expanded programme on immunization (EPI) is an important part of the social commonwealth projects providing health care service by the government, which benefits communities. Government has the responsibility for EPI's financing which should be covered by the national budget. It is essential that the cost of EPI service be scientifically estimated to provide propriety information for policy makers.

METHODSThis study, using the cost accounting theory of health economics, to calculate EPI service cost at different levels. 3 provinces, 3 prefectures, 9 counties, 18 towns and 12 villages were selected from three provinces Guizhou, Heilongjiang and Zhejiang from the western, central and eastern regions of the country.

RESULTSThe average costs for one EPI-targeted child in Guizhou, Heilongjiang and Zhejiang, were 15.68 Yuan, 29.00 Yuan and 31.09 Yuan, and the costs for one dose were 10.99 Yuan, 18.64 Yuan and 16.51 Yuan, respectively. The costs for complete immunization program for one child were 131.88 Yuan, 242.32 Yuan and 280.67 Yuan, respectively. The main factors affecting the cost would include the average personnel cost (salary and benefit cost) by different economic levels of areas, the number of EPI items developed, and the number of total doses for one child.

CONCLUSION(1) Obvious differences were found between different areas. (2) The proportion of the cost was not reasonably set because of the shortage of input. (3) Guideline for different areas to compensate the working item cost according to the number of the items should be formulated.

OBJECTIVETo summarize experiences of operative treatment for Essex-Lopresti injury, and analyze the effect of the compare repair of interosseous membrane of forearm(IOM)on the forearm function.

METHODSTwenty-four patients of Essex-Lopresti injury were treated from January 2005 to December 2013, 16 patients(group A) with radius and/or ulna fractures were treated with open reduction and internal fixation of radius or ulna and repair of forearm bone membrane at the same time, and then treated with open reduction and internal fixation of head of radius, as well as lower ulnar joint fixation or repair of wrist triangle fiber complex. Another 8 patients without radius and or ulna fractures(group B) were treated with open reduction and internal fixation of head of radius, as well as lower ulnar joint fixation or repair of wrist triangle fiber complex. The wrist joint function was evaluated using Cooney wrist functional rating index, and the elbow joint function was evaluated using Mayo elbow-performance score 2 weeks and 2 years after operation.

RESULTSAccording to Cooney wrist functional rating index, 4 patients in group A got a fair result and 12 poor, 2 patients in group B got a fair result and 6 poor 2 weeks after operation; 8 patients in group A got a good result, 6 fair and 2 poor, 5 patients in group B got a good result, 2 fair and 1 poor 2 years after operation. According to Mayo elbow-performance score, 2 patients in group A got a good result, fair and 6 poor, 1 patient in group B got a good result, 5 fair and 2 poor 2 weeks after operation; 8 patients in group A got a good result, 6 fair and 2 poor, 4 patients in group B got a good result, 3 fair and 1 poor. There were no statistically differences between two groups 2 weeks and 2 years after operation.

CONCLUSIONSIt is important to restore the length of radius and/or ulna and maintain the dynamic stabilization of elbow and wrist for treat Essex-Lopresti injury. The repair of IOM has no effect on the forearm function.

OBJECTIVEAllogeneic bone marrow transplantation has been established as a standard method for the treatment of a range of malignant and non-malignant hematologic diseases in children. Unfortunately, fewer than 30% of patients have a human leukocyte antigen (HLA)-matched sibling. Advances in our understanding of the HLA system and the development of large international donor registries encourage the increasing use of unrelated donors as an alternative source of stem cells. The purpose of this study was to evaluate the clinical efficacy and safety of unrelated donor allogeneic bone marrow transplantation (URD-BMT) for the treatment of childhood leukemia.

METHODSSix patients with leukemia received URD-BMT. Two of them suffered from chronic myeloid leukemia (CML), 3 suffered from acute lymphocytic leukemia (ALL) and 1 suffered from acute promyelocytic leukemia (APL) (CR2). All cases were facilitated by Tzu Chi Marrow Donor Registry (TCTMDR). The high resolution DNA test for classIand II was carried out in HLA typing of all donor-receiver pairs. HLA allele matched in three cases, mismatched with one locus in two cases and with two loci in one case. All patients were prepared with cyclophosphamide (CY) 60 mg/kg/day for 2 days (total dose 120 mg/kg) and busulfan (Bu) 1 mg/kg x 4/day for 4 days (total dose 16 mg/kg). Mycophenolate mofetil (MMF), CsA and MTX were given to prevent acute graft-versus-host-disease (aGVHD). CsA of 3 mg/kg/d was continuously given by i.v. infusion, and then 6mg/kg/d by oral. The blood CsA concentration was 200 - 300 ng/ml. MTX was given at the dosage of 15 mg/m(2) on d 1 and 10 mg/m(2) on d 3, 6,9 or 11. MMF was given at the dosage of 0.25 - 0.5 g/d from day 0 to day 120. Prostaglandin E1 was given to prevent the hepatic veno-occlusive disease (VOD), Ganciclovir was used to prevent CMV infection until the CMV antigenemia became negative.

RESULTSAnalysis of DNA short tandem repeats showed total engraftment of donor marrow after transplantation in all cases. The median time when granulocyte exceeded 0.5 x 10(9)/L was 14.5 (13 - 18) days, platelets exceeded 20 x 10(9)/L was 16 (14 - 23) days. The acute GVHD grade II-IV occurred in 2 of 6 (33.3%) patients. There were 3 cases with chronic GVHD and none of them developed with the extensive chronic GVHD. All patients were alive in disease-free situation now with median follow-up 412 (187 - 1338) days.

CONCLUSIONURD-BMT is an effective method for the treatment of childhood leukemia.

BACKGROUNDOocyte vitrification is widely used throughout the world, but its clinical efficacy is inconsistent and depends on the vitrification media. This study compared the developmental potential and clinical results of in vivo matured oocytes cryopreserved with different vitrification media.

METHODSThis retrospective study involved vitrified-warmed oocytes at one in vitro fertilization laboratory. Vitrification media kits comprised the MC kit (ethylene glycol [EG] plus 1,2-propanediol [PROH]), the KT kit (EG plus dimethyl sulphoxide [DMSO]), and the Modified kit (EG plus DMSO and PROH kit). Rates of oocyte survival and subsequent developmental potential were recorded and analyzed. The t-test and the Chi-square test were used to evaluate each method's efficacy.

RESULTSOocyte survival rate was significantly higher for the Modified kit (92.0%) than for the MC kit (88.2%) (P < 0.05) and the KT kit (77.3%) (P < 0.001). The rate of high-quality embryo development in the Modified kit group (35.8%) was significantly higher than in the MC kit group (29.0%) and the KT kit group (28.3%) (P < 0.001). No significant differences were observed in the clinical pregnancy and implantation rates among the MC, KT, and Modified kit groups (37.2% vs. 30.2% vs. 39.6%; 21.9% vs. 18.8% vs. 27.4%, respectively) (P > 0.05). The high-quality embryo rate per warmed oocyte was significantly higher (23.4%) in the Modified kit group than in the other groups (P < 0.001). The embryo utilization and live birth rates per warmed oocyte were the highest in the Modified kit group, but not significantly (P > 0.05).

CONCLUSIONSModified vitrification media are efficient for oocyte vitrification and, with further verification, may be able to replace commercially available media in future clinical applications.

OBJECTIVETo compare the clinical outcomes between HLA allele matched (HLA-M) and 1 approximately 2 alleles disparity mismatched (HLA-mis) unrelated allogeneic bone marrow transplantation (URD-BMT).

METHODSThirty-nine patients received HLA-M and 21 received HLA-mis URD-BMT for the treatment of acute leukemia, chronic myeloid leukemia in chronic phase (CP) and myelodysplastic syndromes (MDS) in our hospital between November 1998 and December 2002. Conditioning regimen was Bu 16 mg/kg plus CTX 120 mg/kg, and mycophenolate mofetil (MMF), CsA and MTX were given to prevent aGVHD.

RESULTSThirty-eight of the HLA-M group and 18 of the HLA-mis group were engrafted successfully. The median follow-up duration was 11 (2.5 - 52.0) months for HLA-M group and 9 (2 - 46) months for HLA-mis group. The 3-year probabilities of disease-free survival (DFS) for HLA-M and HLA-mis group were (79.2 +/- 7.1)% and (45.8 +/- 15.5)%, respectively (P < 0.05). Grade II - IV aGVHD occurred in 10 (26.3%) patients in HLA-M group and 6 (33.3%) in HLA-mis group, respectively (P > 0.05).

CONCLUSIONURD-BMT is an effective modality for the treatment of leukemia and MDS. The outcome after URD-BMT can be optimized by matching the HLA-A, B and DR alleles between the donor and recipient.

OBJECTIVETo study the clinicopathologic features of peripheral T-cell lymphoma, unspecified (PTL-U) with follicular pattern.

METHODSThe clinical data, hematoxylin and eosin-stained sections of lymph node biopsies and follow-up data of 18 cases of PTL-U associated with follicular growth pattern were reviewed and studied. Eight cases of reactive lymphoid hyperplasia were used as controls. Semi-quantitative observation by retiform micrometer rule was carried out. Immunohistochemical study was also performed in all cases. T-cell receptor and immunoglobulin heavy chain gene rearrangement studies were conducted by polymerase chain reaction-based method.

RESULTSThe median age of the patients was 53 years. The male-to-female ratio was 1.57:1 in lymphoma group. All of the lymphoma patients presented with superficial lymphadenopathy, with (8/18) or without B symptoms. Histologically, the lymphoma was characterized by follicles of various sizes and shapes. The T zones were expanded by medium-sized lymphoma cells which contained clear cytoplasm and irregular nuclei. Mitotic figures were commonly identified. Immunohistochemical study confirmed that the lymphoma cells were of T-lineage. The proliferative index, as highlighted by Ki-67, was higher [average = (38.24 +/- 13.42)%/mm2] than that in the control group. T-cell receptor gene rearrangement was demonstrated in 71.4% (10/14) of the lymphoma cases.

CONCLUSIONSA definitive diagnosis of PTL-U with follicular pattern can be made on the basis of morphologic examination, immunohistochemical assessment and clinical features. Cases with atypical features can further be delineated by molecular analysis. Long-term follow up of these patients is prudent.
