OBJECTIVETo introduce different surgical treatment for gyncomastia at different grades.

METHODS37 cases with gynecomastia were divided into three grades as: grade I with fat as main tissue, grade II with proliferated fibro-gland as main tissue, grade III with big and ptosis breasts and sagging skin. Different surgical methods were chosen according to the different grades of gyncomastia. These include liposuction, subareolar fibroglandular tissue removing, combined technique of the two methods, and breasts resection with free transplantation of nipple-areola complex.

RESULTSAll patients were satisfied for the appearance of post-operative flat male chest. Complications, such as scar, numbness of nipple and areola were acceptable for them.

CONCLUSIONSDifferent surgical methods should be chosen for the gynecomastia at different grades. It can improve both the physical and psychological problems for patients.

OBJECTIVETo investigate the appearance and clinical value of MRI in the diagnosis of embryonal rhabdomyosarcoma in nasal cavity and paranasal sinuses.

METHODSThe clinical, pathological and MRI findings of five patients with pathology proved embryonal rhabdomyosarcoma in nasal cavity and paranasal sinuses were retrospectively analyzed.

RESULTSThe major clinical symptoms included nasal obstruction (4 cases), exophthalmus (4 cases), decreased eyesight (2 cases), epistaxis (1 case), decreased olfactory sensation (1 case) and restriction of eyeball movement (1 case). All 5 cases involved multi-location. Among them, 4 cases mainly located in the ethmoid sinus, one mainly located in the nasal septum. According to the IRS, 1 case was at stage II, the other 4 cases were at stage III. Compared to the grey matters, on T1 weighted image, the masses were homogenously isointensity in 2 cases, isointensity with patchy hyperintensity in 3 cases. On T2 weighted images, the masses were slightly hyperintensity with patchy hypointensity in 2 cases. Slightly hyperintensity with patchy hyperintensity in 3 cases. All 5 cases were markley heterogeneously enhanced after administration of contrast agents, with patchy of non-enhanced area. Of them, two were grape-like enhanced. Four cases presented with intratumor hemorrhage. Five with bony destruction. All of the 5 cases showed orbits and anterior cranial fossa meningeal involvement.

CONCLUSIONSThere are some special MRI findings in embryonal rhabdomyosarcoma located in nasal cavity and paranasal sinuses. MRI can depict the encroachment of the tumor accurately, and may play an important role in clinical staging and in curative effect evaluation.

OBJECTIVETo observe the occurrence and progression of liver fibrosis induced by pig serum exposure and bile duct ligation, and analyze the relationship between hepatic inflammation and liver fibrosis.

METHODSChronically immune-mediated liver fibrosis was induced in rats by weekly injection of pig serum (IPS) into the peritoneal cavity at 3 ml/kg for 12 weeks. Cholestatic fibrosis was induced by common bile duct ligation (BDL). The Knodell score was used to evaluate the histological changes in the liver, and immunohistochemistry was performed using anti-SMA, anti-ED1, anti-CK7, and anti-CD45 antibodies. Quantitative real time PCR (qPCR) analysis was employed to quantify the mRNA expression of the genes related to inflammation, including interleukin-1beta (IL-1beta), IL-6, monocyte chemotactic protein-1, tumor necrosis factor-alpha, regulated upon activation normal T cell expressed and secreted (RANTES), transforming growth factor-beta, platelet-derived growth factor A, as well as the genes associated with fibrogenesis, namely collagen 1, alphaSMA, MMP-9 and TIMP-1.

RESULTSKnodell scores for periportal necrosis, intralobular degeneration and focal necrosis, and portal inflammation were all significantly higher in the BDL group than in the IPS group (P<0.01), whereas the scores for fibrosis was higher in the IPS group (P<0.05). Immunohistochemistry showed obvious inflammation with numerous alphaSMA-positive cells in the liver of the rats in BDL group; the liver of the rats in IPS group showed numerous alphaSMA-positive myofibroblasts with limited inflammatory cell infiltration. qPCR demonstrated a significant up-regulation of the genes related to extracellular matrix remodeling such as collagen 1 (P<0.01), alphaSMA (P<0.01), MMP-9 (P<0.01) and TIMP-1 (P<0.01) in the rat liver in IPS group compared with those in the normal control group, and the mRNA expressions of the inflammation-related cytokines, except for RANTES, were comparable with those in the control. In contrast, the BDL group showed a significant up-regulation of all the pro-inflammatory genes examined with also increased expression of the fibrogenesis-related genes (P<0.05).

CONCLUSIONLiver fibrosis induced by IPS is characterized by active ECM remodeling in the absence of obvious inflammation, indicating that chronic development of liver fibrosis can be independent of active hepatic inflammation. BDL-induced liver fibrosis highlights obvious inflammation and fibrous proliferation in the liver.

OBJECTIVEIt is revealed that circulating fibrocytes are elevated in patients/animals with cardiac fibrosis, and this review aims to provide an introduction to circulating fibrocytes and their role in cardiac fibrosis.

DATA SOURCESThis review is based on the data from 1994 to present obtained from PubMed. The search terms were "circulating fibrocytes " and "cardiac fibrosis ".

STUDY SELECTIONArticles and critical reviews, which are related to circulating fibrocytes and cardiac fibrosis, were selected.

RESULTSCirculating fibrocytes, which are derived from hematopoietic stem cells, represent a subset of peripheral blood mononuclear cells exhibiting mixed morphological and molecular characteristics of hematopoietic and mesenchymal cells (CD34+/CD45+/collagen I+). They can produce extracellular matrix and many cytokines. It is shown that circulating fibrocytes participate in many fibrotic diseases, including cardiac fibrosis. Evidence accumulated in recent years shows that aging individuals and patients with hypertension, heart failure, coronary heart disease, and atrial fibrillation have more circulating fibrocytes in peripheral blood and/or heart tissue, and this elevation of circulating fibrocytes is correlated with the degree of fibrosis in the hearts.

CONCLUSIONSCirculating fibrocytes are effector cells in cardiac fibrosis.

OBJECTIVETo discuss the resection of tumors, reconstruction of defects and the postoperative complications.

METHODSThirty-one patients with tumors around acetabular were treated surgically in People's Hospital between July 1997 and July 2003. The series comprised 19 males and 12 females. Twelve patients were diagnosed with chondrosarcoma, 1 with Ewing sarcoma, 3 with osteosarcoma, 1 with lymphoma, 1 with carcinosarcoma, 1 with malignant fibrohistiocytoma (MFH), 2 with myeloma, 9 with giant cell tumor (GCT), 1 with aneurysmal bone cyst. Among 31 patients with peri-acetabular tumors, 8 were reconstructed with hemi-pelvic prosthesis, 7 with saddle prosthesis, 6 with cauterized tumor bone and total hip arthroplasty, 10 with total hip replacement after curettage of lesion and cemented.

RESULTSAmong 21 patients who underwent tumor resection and reconstruction in region II, 6 had local relapse. Two of 3 patients with osteosarcoma were dead. Five of 12 patients with chondrosarcoma were free of disease. Twenty-one patients with acetabular reconstruction after resection of lesions in region II could sit and stand normally and walked with a cane, several of which even had normal gait.

CONCLUSIONAllograft or pelvic prosthesis can be used to reconstruct the acetabulum after resection of tumors. We must pay more attention on the following points in the surgical treatment of periacetabular tumors: (1) Extensively resect tumors as far as possible; (2) Be acquainted with advantages and disadvantages of different reconstructive methods of acetabulum to prevent the complications; (3) The reconstructed acetabulum is unstable, so the patients must stand with a cane to protect the reconstructed hip joint; (4) Prevent wound necrosis and infection; (5) Surgical treatment of pelvic tumors would easily result in poor wound healing especially in the patients receiving chemotherapy or radiotherapy because of extensive soft tissue stripping. The destroyed soft tissue caused by chemotherapy or radiotherapy may increase the great tissue tension after implantation of allograft. And the factors of poor blood supply and hematoma in the wound theoretically increase the chance of infection.

OBJECTIVETo discuss the effect and complication of spinal operation combined with vertebroplasty in treating for multiple spinal neoplasm.

METHODSDuring the last two years, 20 patients (13 male and 7 female) with multiple spinal neoplasm including metastases, multiple myeloma and lymphoma were treated by operation combined with vertebroplasty, 2 vertebral body segments were involved in 5 cases, 3 to 4 vertebral body segments were involved in 11 cases, more than 5 segments were involved in other 4 cases. Neurological function deficit and severe pain were seen in all the cases. Patients were evaluated by Tomita prognostic scoring system before the operation; The average point was 7.2 (from 3 to 9 points).

RESULTSThe pain relief rate was 85% (17/20), and neurological recovery was found in 10 out of 12 patients who had neurological deficit. According to the system of Frankel and neurological function, 1 patient recovered from grade B to grade C after the operation, and there was no change in another patients who was evaluated as grade A before the operation. The main complication of vertebroplasty was leakage of PMMA. Six patients had leakage of PMMA into adjacent structures in this series.

CONCLUSIONSBetter results of pain relief and neurological function recovery and living quality can be achieved by surgical palliation of operation combined with vertebroplasty for multiple spinal neoplasm.

To explore the efficacy of the different combinations of stem cell factor (SCF), FLT3 ligand (FL) and interleukin (IL) 2, 7, 15 on the induction and expansion of cord blood (CB) derived CIK/ NK cells in vitro, according to the different combinations of cytokines, combinations of cytokines were divided into 3 groups: group A (SCF + IL2 + IL7 + IL15), group B (SCF + FL + IL2 + IL7 + IL15) and group C (IL2 + IL7 + IL15 as control group). At 21 days of culture, the proportion and the expansion rate of CD3(+)CD56(+) CIK cells and CD3(-)CD56(+) NK cells were measured. The results showed that at 21 days in culture, the percentages of CD3(+)CD56(+) CIK cells derived from CB-MNC in group A, B and C were (19.84 +/- 2.93)%, (26.20 +/- 4.05)%, (24.03 +/- 4.99%) and that of NK cells were (49.60 +/- 1.40)%, (51.16 +/- 6.45)% and (30.85 +/- 8.12)%, respectively. The proliferation of CD3(+)CD56(+) CIK cells and CD3(-)CD56(+) NK cells was the most effective in group B (SCF + FL + IL2 + IL7 + IL15). Expansion multiple of CIK cell number increased from 575.81 +/- 221.72 (control) to 796.09 +/- 278.47 with peak value of 1 313, and that of NK cells increased from 30.39 +/- 14.47 (control) to 65.85 +/- 30.83 with peak value of 121.06. In conclusion, a proper cytokines (SCF + FL + IL2 + IL7 + IL15) culture system can effectively induce and expand CB CD3(+)CD56(+) CIK cells and CD3(-)CD56(+) NK cells simultaneously.

OBJECTIVETo compare efficacy of different adjuvant chemotherapy regimens for stage II-III gastric cancer after D2 gastrectomy in Asian patients.

METHODSAssociated literatures were searched through electronic databases and hand-searching. Prospective randomized clinical trials (RCTs) comparing adjuvant chemotherapy after D2 gastrectomy with surgery alone were included in the study. Overall survival and disease-free survival were chosen as the endpoints. Relative hazard was analyzed by Bucher adjusted indirect comparison.

RESULTSTwo RCTs were selected, including comparison between S-1 versus surgery alone and comparison between XELOX versus surgery alone. There was no statistical difference in overall survival between the two regimens (HR=0.94, 95%CI:0.62-1.44, P=0.79). The recurrence risk of S-1 was slightly higher as compared to XELOX, but no statistical difference was found (HR=1.11, 95%CI:0.80-1.53, P=0.54).

CONCLUSIONThe adjuvant chemotherapy with S-1 is similar to XELOX for stage II-III gastric cancer after D2 gastrectomy in Asian patients.
