OBJECTIVEThe inverted "T" operation is a typical and classic method for breast hypertrophy. Although having good results, it leaves significant scar and tends to have bottom-out deformity with time. The purpose of this study is to introduce our experience in vertical mammaplasty.

METHODSThe typical Lejour's design was used. The lower part of the breast was excised. The nipple-alveolar complex was elevated to a proper position with the superior dermal-glandular pedicle. Only vertical scar was left after the skin was closed.

RESULTS24 patients were treated using this method. The results were satisfactory except unilateral nipple-alveolar complex necrosis occurred in one patient. Another patient had a minor revision for the dog-ear 6 months after breast reduction.

CONCLUSIONSVertical reduction mammaplasty is effective with reduced scar and highly satisfactory results. It deserves recommendation.

BACKGROUNDMore patients receive organ transplantation surgeries due to the advancement in immunosuppressive agents and surgical techniques. Some of those patients may need to undergo plastic or reconstructive surgery. Long-term use of immunosuppressive agents raises some serious problems. Therefore, this study aimed to introduce our experience about the safety and effectiveness of plastic surgeries after solid organ allograft transplantation.

METHODSA retrospective review of 17 transplant recipients who underwent different reconstructive or cosmetic operations was carried out. The subjects included 1 heart transplant, 1 liver transplant and 15 kidney transplant recipients.

RESULTSAll patients tolerated the plastic surgery procedures well. Flaps and skin grafts were the main constructive methods. There were no postoperative infections and wound dehiscence. Transferred flaps survived completely. Skin grafts took well. Three of the cosmetic surgery patients were satisfied with the results.

CONCLUSIONSImmunosuppressed organ transplant recipients can successfully undergo major reconstructive and cosmetic surgery when given special attention.

OBJECTIVETo report the reduction mammaplasty with vertical incision and superior wide pedicle.

METHODSTypical Lejour mosque-dome design was performed. The inferior part of glandular tissue and skin were excised. The nipple-and-areola complex (NAC) was elevated to normal position with superior wide pedicle. The breast morphology was modified with vertical scar left.

RESULTS46 patients were treated. 4 patients had unilateral breast reduction. 14 breasts had wound dehiscence. 3 breasts received debridement, others were treated conservatively with dressings. No complete NAC necrosis occurred.

CONCLUSIONSThe reduction mammaplasty with vertical incision and superior wide pedicle is a safe and effective method with a low risk of NAC necrosis.

BALB/c mice were immunized with purified White spot syndrome virus (WSSV).Six monoclonal antibody cell lines were selected by ELISA with VP28 protein expressed in E.coll in vitro neutralization experiments showed that 4 of them could inhibit the virus infection in crayfish.Westernblot suggested that all these monoclonal antibodies were against the conformational structure of VP28.The monoclonal antibody 7B4 was labeled with colloidal gold particles and used to locate the VP28 on virus envelope by immunogold labeling.These monoclonal antibodies could be used to develop immunological diagnosis methods for WSSV infection.

Serum levels of soluble MHC class I-related chain A (sMICA) are related with the prognosis of various types of cancer; however, few studies on the prognostic value of sMICA in hepatocellular carcinoma (HCC) have been reported. In this study, we retrospectively investigated the relationship between sMICA levels and clinical features of advanced HCC, and we assessed the prognostic value of sMICA in advanced HCC. Furthermore, the relationship of serum sMICA levels and natural killer group 2, member D (NKG2D) expression on natural killer (NK) cells was also evaluated. We detected sMICA levels in the serum of 60 advanced HCC patients using enzyme-linked immunosorbent assay (ELISA) and measured expression levels of NKG2D on NK cells using flow cytometry. We found that serum sMICA levels in HCC patients were in the range of 0.10-6.21 ng/mL. Chi-square analyses showed that sMICA level was significantly related with only tumor size. Survival analysis showed that a high sMICA level was significantly related with poor prognosis among HCC patients. Multivariate analyses indicated that sMICA was an independent prognostic factor. In addition, the levels of CD56+NKG2D+ NK cells were within the range of 11.2%-55.4%, and correlation analyses indicated that sMICA level was negatively correlated with the level of NKG2D+ NK cells. Our results suggest that serum sMICA levels may be an independent prognostic factor for advanced HCC.

OBJECTIVEThe aim of this study was to analyze the clinical characteristics and prognostic factors in patients with cancer of unknown primary site (CUP).

METHODSThe clinical and follow-up data of 68 CUP patients (46 adenocarcinoma patients, 22 squamous cell carcinoma patients), were retrospectively analyzed. Univariate and multivariate analysis were conducted to determine the correlation of survival with clinical features, tumor markers, blood test, liver function and so on.

RESULTSThe median survival time of the 68 CUP patients was 123 days. The results from univariate Cox regression analysis showed that the prognostic factors were related to a performance status, presence or absence of liver metastases, the number of metastatic sites, carcinoembryonic antigen (CEA), lactate dehydrogenase (LDH), hypoalbuminemia, hypohemoglobinemia and lymphocyte count. Multivariate Cox regression analysis of the clinical factors identified that a performance status (PS) ≥ 2, liver metastasis, elevated serum carcinoembryonic antigen (CEA) and lactate dehydrogenase (LDH) levels, hypoalbuminemia (< 35 g/L) and lymphopenia (≤ 0.7 × 10(9)/L) were significant independent unfavorable predictive factors. Based on the number of the unfavorable predictive factors, we divided all the patients into three subgroups: subgroup involving 0-1 unfavorable factor, subgroup involving 2 - 3 unfavorable factors and subgroup involving 4 - 6 unfavorable factors. The median survival time was 390 days, 138 days and 77 days, respectively, in the 3 subgroups. Compared with the other two groups, the survival of the subgroup involving 0 - 1 unfavorable factor was significantly longer (P < 0.05), the survival between the subgroup involving 2 - 3 unfavorable factors and subgroup involving 4 - 6 unfavorable factors was not significantly different (P > 0.05).

CONCLUSIONSA performance status ≥ 2, liver metastasis, elevated serum carcinoembryonic antigen and lactate dehydrogenase levels, hypoalbuminemia and lymphopenia are independent unfavorable prognostic factors in patients with cancer of unknown primary site. The patients who had more than 2 unfavorable prognostic factors have a worse prognosis.
