Objective To explore a new surgical procedure for phallic reconstruction. Methods Since Dec 2003 to Nov 2006,4 patients with penile loss were reconstructed by transferring a deep in-ferior epigastric perforator(DIEP)flap with implanting the 12th costal cartilage. Results All of the flaDs survived successfully.With the follow-up from 5 months to 3 years,the appearance oi the neope-nis and donor-site scar was satisfactory. No one developed fistula or urethral stenosls, All patients were reported the return of erogenous sensibility of the neopenis leading to orgasm and achmving Pene-tration during sexual intercourse. Conclusions This new procedure may provide an esthetlcaIlY ac-ceDtable and functional neophallus.It might be a new alternative in penile reconstruction.

Objective:To investigate the prognostic significance of high sensitivity-C reactive protein (Hs-CRP) in patients with peripher-al T-cell lymphoma (PTCL). Methods:A total of 234 newly diagnosed PTCL patients with a median age of 48 years were analyzed retro-spectively. Serum Hs-CRP levels and other factors, including tumor stage and international prognostic index (IPI), were determined. Af-ter a median follow-up of 23 months, the relationship between Hs-CRP and overall survival (OS) was observed. Results:Serum Hs-CRP level positively correlated with IPI score (r=0.132, P<0.001), tumor stage (r=0.183, P=0.005), B symptoms (r=0.225, P=0.001), and lactic dehydrogenase (r=0.169, P=0.009), but negatively correlated with plasma albumin levels (r=?0.343, P<0.001), hemoglobin concentra-tion (r=?0.239, P<0.001), and platelet count (r=0.131, P=0.045), and is uncorrelated with age (P>0.05), gender (P>0.05), fitness score (P>0.05), and leukocyte count (P>0.05). Patients with serum Hs-CRP levels≤10 mg/L had better OS than patients with serum Hs-CRP levels>10 mg/L. Univariate and multivariate Cox regression models showed that platelet count, Hs-CRP, albumin levels, and IPI score were independent adverse prognostic factors. Conclusion:The baseline Hs-CRP level can serve as a major indicator of prognosis in PT-CL patients.

OBJECTIVETo observe the short- term effects of hemogram in donors after peripheral blood stem cell（PBSC）collection and donors' tolerance.

METHODSA total of 166 related allogeneic donors were selected from The First Affiliated Hospital of Medical School of Zhejiang University between January 2013 and December 2014, including 86 male and 80 female. All donors accepted granulocytecolony- stimulating factor（G-CSF）5-10 μg·kg⁻¹·d⁻¹ until collection finished and were measured by blood cells count before and after PBSC collection.

RESULTSAfter PBSC collection, the hemoglobin level decreased from 145（94-181）g/L to 138（93-167）g/L, and the platelet counts decreased in all donors from 231（105- 490）× 10⁹/L to 95（39- 210）× 10⁹/L. The amount of hemoglobin contamination in collection products was weak correlated with the decreased hemoglobin in peripheral blood（r=0.297, P=0.017）, and the platelet contamination was high correlated with that decreased in peripheral blood（r=0.719, P<0.001）. The decline of hemoglobin level after twice PBSC collection was of no significant difference between four groups in different ages（P≥0.05）. The decline of platelet counts was out of a significant difference（P> 0.05）. In addition, the decline of hemoglobin level after once and twice PBSC collection was of a significant difference between four groups in different body mass index（BMI）（P=0.003 and P<0.001）, especially in thinner group with obvious decrease. But the decline of platelet counts was out of a significant difference （P>0.05）.

CONCLUSIONThe hemoglobin level decreased mildly in healthy allogeneic hematopoietic stem cell donors after PBSC collection and it is better to adjust parameters every time to ensure their safety for thinner donors. However, it will increase the risk of platelet decline, which is unrelated with ages and BMI and can be tolerated.

Objective: To analyze the prognostic value of CD7 expression in newly diagnosed acute myeloid leukemia (AML) patients, and to further explore the correlation between CD7 expression and CEBPA mutation, and to clarify the prognostic value of CD7⁺ in AML patients with wild-type (WT) or mutant-type (MT) CEBPA. Methods: The clinical data of 298 newly diagnosed non-M₃ AML patients between January 2010 and December 2016 were analyzed retrospectively. The clinical characteristics and prognosis of CD7⁺ and CD7^- patients were respectively compared in all patients, and in patients with WT and MT CEBPA. The relationship between CD7 expression and CEBPA mutation was determined by chi-square, and the effects of CEBPA mutation on survival and prognosis in CD7⁺ group by Kaplan-Meier method. Results: In CD7⁺ group, the frequencies of CEBPA mutation were 10.1% (single site) and 33.9% (double site) , significantly higher than those of the CD7^- group (5.3% and 4.2%) (P=0.000) . Subgroup prognostic analysis showed a lower CR rate (P=0.001) and a higher RR (P=0.023) in CD7⁺ group comparing to those of CD7^- group in AML patients with wild type CEBPA. There were no statistical difference between CD7⁺ group and CD7^- group in overall survival (OS) and disease free survival (P>0.05) , while in the CEBPA mutant group the CD7⁺ group has higher OS (P=0.019) and DFS (P=0.010) . Based on the CD7 expression and CEBPA mutation, 298 cases were divided into 3 subgroups, named as CD7⁺-CEBPA MT group, CD7^- and CD7⁺-CEBPA WT group. The 3-year OS of the 3 groups were 80.2%, 48.0% and 30.6%, respectively (P<0.001) , and the 3-year DFS were 74.1%, 37.4% and 22.2%, respectively (P<0.001) . Conclusion The CEBPA mutation rate was higher in CD7⁺ AML patients then that of CD7^- patients. CD7 expression has opposite prognostic significance in AML patients carrying the wild-type or mutant-type CEBPA. Based on CD7 expression and CEBPA mutation, a new risk stratification model can be established, which is helpful to guide the clinical individualized treatment for AML patients.
