OBJECTIVETo investigate the influence of the rate of morphologically normal sperm (MNS) on the clinical outcomes of conventional in vitro fertilization (IVF) in patients with one retrieved oocyte.

METHODSFrom January 2013 to January 2015, a total of 256 couples with one retrieved oocyte underwent conventional IVF in our center. According to the rate of MNS, the patients were divided into two groups: MNS < 4% (134 cycles) and MNS ≥ 4% (122 cycles). We compared the rates of no transferrable embryo cycles, fertilization, cleavage, normal fertilization, abnormal fertilization, high-quality embryo and transferrable embryo between the two groups. A total of 75 fresh embryo transfer cycles were performed, 43 in the MNS < 4% group and the other 32 in the MNS ≥ 4% group. We also compared the rates of implantation, clinical pregnancy and abortion between the two groups.

RESULTSThere were no statistically significant differences between the two groups in the rates of no transferrable embryo cycles, fertilization, cleavage, normal fertilization, abnormal fertilization, high-quality embryo and transferrable embryo (P > 0.05). The rates of implantation, clinical pregnancy and abortion exhibited no remarkable differences either in the fresh embryo transfer cycles between the two groups (P > 0.05).

CONCLUSIONThe rate of MNS does not affect the clinical outcomes of conventional IVF in patients with one retrieved oocyte.

Objective To report 6 cases of hydroa vacciniforme-like cutaneous lymphoma,and to inves- tigate the relationship between this disorder and Epstein-Barr virus(EBV)infection.Methods Pathological and immunohistochemical examinations were performed in the biopsy specimens obtained from all 6 patients. Skin lesions were subjected to EBV encoded RNA(EBER)detection by in situ hybridization.Serological assay and quantification of EBV DNA were performed.Results All the 6 patients had recurrent papules, papulovesicles,necrosis and variola-like scar with chronic intermittent fever;four of the patients also presented with edema of the face,hands and feet.Pathologically,there were multilocular vesicles in the epidermis,and large numbers of infiltrating lymphocytes through the dermis.The cells were atypical with mitotic figures. Immunohistochemical staining of the lesions of 4 patients showed large quantities of cells expressing CD56, scattered cells expressing CD3 and CD45RO,and cells expressing grazyme B and T cell intracellular antigen-1 (TIA-1);a diagnosis of hydroa vacciniforme-like cutaneous NK/T lymphoma was made in these 4 cases. In the lesions of another 2 patients,the cells expressing CD3 and CD45RO,but not CD56,were observed; the diagnosis of hydroa vacciniforme-like cutaneous T-cell lymphoma was made in them.EBER was detected in the tumor cells of all the 6 patients.The IgG titers of anti-Epstein-Barr viral capsid antigen increased in all patients(1:5120 in 2 cases,1:2560 in 2 cases,1:1280 in 2 cases).The copies of EBV DNA were increased in the peripheral blood of both the two detected cases.A chronic active EBV infection was confirmed in all patients.Conclusions Hydroa vacciniforme-like cutaneous lymphoma is clinically characterized by edema of face,hands and feet,vesicular eruptions and variola like scars;histologically,it is characterized by infiltrates of atypical cells consistent with lymphoma,and necrosis in the center of vessels.NK/T is the primary immunophenotype of this disease.There is a close association between chronic active EBV infection and hydroa vacciniforme-like cutaneous lymphoma.

Objective To review the surgical managements of patients with traumatic false aneu- rysms in the extremities.Methods From January 1990 to April 2006,17 patients with traumatic false aneurysms in the extremities were admitted into our hospital.Fourteen patients were treated by vascular repair including vascular repair in seven cases,end to end anastomosis in one,synthetic grafting in one, autogenous vein grafting in one,and direct ligation in four.Three patients were treated nonoperatively, but with local compressive dressing.Results There were no deaths or gangrenes in all cases.The clinical manifestations vanished after the treatment.The mean follow-up period was 13.2 months.The function of the injured extremities recovered satisfactorily.Conclusion Different types of traumatic false aneurysms should be managed by different therapeutic procedures after the diagnoses is made.

Objective Multimeric cyclic RGD (Arg-Gly-Asp) peptides are capable of improving the integrin αvβ3-binding affinity due to the polyvalence effect.In this study,the authors prepare 99Tcm-la-bearing cyclic RGD tetramer E{E[c(RGDfK)]2}2,and evaluate its biodistribution and imaging in nude mice beating U87 MG human glioma xenografts with integrinαvβ3-positive.Methods 99Tcm-hydrazino-nictinamide (HYNIC)-E{E[c(RGDfK)]2}2 was prepared by two-step method,while HYNIC wag chosen as bifunctional chelator,and tricine and trisodium triphenylphosphine-3,3,3-trisuifonate (TPPTS) as coligands.The af-finity of c (RGDyK) monomer,HYNIC-E[c(RGDfK)]2 dimer and HYNIC-E{E[c(RGDfK)]2}2 tetramer to integrin αvβ3 was compared by in vitro competitive assay against binding of 125I-c(RGDyK)to integrin αvβ3.positive U87 MG human glioma cells.The biodistribution [the percentage of injection dose per gram of tissue(%ID/g)] and imaging were performed in nude mice bearing UB7MG human glioma xenografts.Re-suits The labeling yield of 99Tcm-HYNIC-E{E[c(RGDfK)2}2 was over 95%,and the radiochemical purity was more than 99%after purification with Sop-Pak C18 cartridge.The 50%inhibiting concentration (IC30) val-ues of c(RGDyk),HYNIC-E[c(RGDfK)]2 and HYNIC-E{E[c(RGDfK)]2}2 were 85.9,9.5 and 4.5 nmol/L, respectively.The result indicated that RGD tetramer possessed a significantly higher affinity to in-tegrinαvβ3.The biodistribution data showed that 99Tcm-HYNIC-E{E[c(RGDfK)]2}2 was excreted mainly through kidneys.The tumor uptake of 99Tcm-HYNIC-E{E[c(RGDfK)]2}2 was two times higher than 99Tcm- HYNIC-E[c(RGDfK)]2,at 1h postinjection,with the uptake of(10.32±0.07)%ID/g and(5.15±0.52)%ID/g,respectively,which was consistent with the in vitro competitive binding data.The tumor up-tale of 99Tcm-HYNIC.E{E[c(RGDfK)]2}2 was still as higher as(9.35±1.35)%ID/g at 4 h postinjec-tion, which demonstrated that the retention time of radiotracer in tumor was long enough.The imaging showed that tumor was clearly visualized at 1h postinjection,and the image at 4 h postinjection Was better.Conclusion The higher tumor uptake and longer retention time in tumor make 99Tem-HYNIC-E{E[c(RG-DfK)J 2}2 a promising radiotracer for integrinαvβ3-positive tumors imaging,furthermore,suggest that radi-onuelides(such as 90Y).1abeled RGD tetramer is more suitable for the therapy of integrin αvβ3-positive tumors.

BACKGROUNDIt is well accepted that the minimally invasive surgery (MIS) for total hip arthroplasty (THA) should combine with less or no muscle damage and is different from mini-incision technique and MIS should have better outcomes than mini-incision surgery. The aim of current analysis was to apply an explicitly defined sub-group analysis to confirm whether this hypothesis is true.

METHODSA computerized literature search was applied to find any data concerning MIS or mini-incision THAs. A multistage screening was then performed to identify randomized studies fulfilling the inclusive criteria for the analysis. The data were extracted, and sub-group analyses of MIS or mini-incision surgery for different kinds of outcomes were carried out. The P(sub) value for difference between MIS sub-group and mini-incision sub-group was also calculated.

RESULTSEleven studies that fulfilling the inclusion criteria were included, with 472 cases in the study group (MIS or mini-incision) and 492 cases in the conventional group. The overall analysis showed the study group would achieve less surgical duration (P = 0.037), intraoperative blood (P < 0.001) and incision length (P < 0.001) than conventional group. The difference between sub-groups showed, the MIS would achieve shorter incision length (P(sub) < 0.05) and bigger cup abduction angle (P(sub) < 0.05), and cause more blood loss (P (sub) < 0.05) than mini-incision technique. Other indexes were comparable between the two sub-groups.

CONCLUSIONSThough further high quality studies are still needed, the result of current analysis offered an initial conclusion that MIS THA failed to achieve a better clinical outcome than mini-incision technique. The exact definition of MIS still needs to be improved.

OBJECTIVEThe aim of the study was to review the cases of Kawasaki Disease (KD) and analyze the clinical features especially their cardiac complications.

METHODSTotally 283 patients with KD were hospitalized from 1992 to 2002. Their clinical features and factors associated with increased risk of coronary artery aneurysms were reviewed.

RESULTS(1) Among the 283 KD patients, 186 were male and 97 were female. The male-female ratio was 1.9:1. Most of them (71%) were younger than 3 years old. Seasonal peak was in spring and summer (from May to Aug). Depending on the criteria of KD, 228 (81%) were diagnosed as typical KD and 55 (19.4%) were atypical KD. All patients had fever, lasting for 6.1 days. The most common clinical features were oral mucosal changes (97.5%) and cervical lymphadenopathy (95.4%), conjunctivitis (91.2%). And changes in the extremities (89.8%) and rash (81.5%) were also noted. (2) Before the treatment, coronary artery abnormalities were seen in 103/279 (36.9%), which occurred within 4 - 30 days of fever onset. Two weeks after intravenous gamma globulin (IVIG) treatment, the new cases of coronary artery abnormalities were 28/211 (13.3%). The prevalence of coronary artery aneurysms (CAA) with KD was 4.7%. The risk factors of CAA were male cases (P < 0.05) and fever lasting longer than 9 days (P < 0.05). Other cardiac abnormalities in acute phase included left atrial and ventricular enlargement (40/279, 14.3%) and changes in ECG (57/274, 20.8%). The pericardial effusions were found in 11 cases (3.9%).

CONCLUSIONSCardiac complications of KD occurred in the early period of KD. The new cases of coronary artery abnormalities were 13.3% after IVIG treatment. The risk factors of CAA included male cases and fever lasting for longer time.

OBJECTIVETo continuously observe the long-term effects of synovectomy for improving joint damage and quality-of-life in patients with the rheumatoid knee.

METHODSTwenty-one consecutive patients with rheumatoid arthritis (RA) involving 24 knees underwent open synovectomy from November 1988 to January 1997 between November 1988 and January 1997. The changes in radiographic damage were assessed with Larsen score on plain films before and 6 months after surgery with subsequent annual assessment for 8 years, and the functional recovery of the patients was also evaluated with Health Assessment Questionnaire (HAQ) at the same time.

RESULTSThe radiographic joint damage and juxta-articular osteoporosis or bone erosion was ameliorated after surgery in all the patients. Larsen score began to decrease 6 months after the operation, and the best effects were achieved at one year and maintained for at least 5 years after the operation, but then followed by recurrence of joint lesions. HAQ scores were improved after the surgery with the best effects observed 6 months after the operation lasting for over 2 years. HAQ score gradually decreased 4 years after the operation till reaching the preoperative scores.

CONCLUSIONSynovectomy in the patients with rheumatoid knee not only reverses progressive joint damage, but also improves juxta-articular bone erosions and the patients' quality of life. However, radiographic joint damage and functional deterioration may recur due to hyperplasia of the inflammatory synovium in the long term after operation, suggesting that the inflammatory synovium participates in local joint damage with bone erosions and systemic pathologic process of RA.
