OBJECTIVETo summarize and analyze the experience in diagnosis and treatment of primary malignant tumors of the heart and pericardium.
METHODSThe clinical data of 24 patients with malignant tumors of the heart and pericardium treated in our hospital between Jun. 1980 and Mar. 2008 were retrospectively analyzed and the related literature was reviewed.
RESULTSAll 24 patients received surgical treatment. Radical resection in 10 cases and partial resection in 6 cases were performed, and the remaining 8 patients received only surgical exploration due to unresectable tumors. One patient died of cardiopulmonary failure in early postoperative stage and all the other patients died within 4 years after operation due to recurrence or metastases.
CONCLUSIONEchocardiography, CT, MRI, 3D-CT, CT of coronary artery and cardiac angiography are helpful for the diagnosis and selection of operation mode. Histological examination is necessary for the final diagnosis. Early diagnosis and surgical resection of the tumor as complete as possible, and combination with post-operative radiotherapy and/or chemotherapy may improve the survival of the patients.

OBJECTIVETo investigate the incidence and risk factors of acute kidney injury (AKI) within the first postoperative week after off-pump or on-pump coronary artery bypass (OPCAB or CCAB) surgery.
METHODSConsecutive patients underwent CABG between January 1990 and August 2006 in our institution and had normal serum creatinine (Scr) and estimated creatinine clearance (Ccr) values before operation were retrospectively analyzed. Multivariate logistic regression analysis was performed to identify risk factors for the development of AKI defined as Scr 130 - 199 micromol/L or Ccr 30 - 60 mlxmin(-1)x1.73 m(-2).
RESULTSIncidence of AKI was significantly higher in patients underwent CCAB compared to those underwent OPCAB (63/331 vs. 61/518, P < 0.01). Peak Scr value was seen at 12th hour post OPCAB and 24th hour post CCAB, respectively. The rapid recovering of Scr occurred between 24th hour to 48th hour in patients underwent OPCAB and 48th hour to 72th hour in patients underwent CCAB surgery. Multivariate forward stepwise logistic regression analysis showed that LVEF < 30%, pulse pressure >/= 60 mm Hg (1 mm Hg = 0.133 kPa), peripheral vascular disease, diabetes, emergent procedure, triple-vessel disease, higher body mass index (kg/m(2)), intraoperative and postoperative IABP, NYHA class III or IV and cardiopulmonary bypass were risk factors for the development of postoperative AKI following CABG, while LVEF > 50% and intraoperative and postoperative IABP were associated with lower incidence of AKI (OR < 1).
CONCLUSIONAKI is not a rare complication post OPCAB or CCAB surgery, especially in patients with reduced LVEF, increased pulse pressure, peripheral vascular disease, diabetes, emergent procedure, triple-vessel disease, higher body mass index, intraoperative and postoperative IABP.

OBJECTIVETo establish a standardized operation procedure for pulsed-field gel electrophoresis (PFGE) on Leptospira interrogans as well as a figure digital database to develop the Chinese representative reference strains.
METHODSUnder the characteristics of strains and referring to the other SOPs of PFGE on pathogens provided by CDC and PulseNet Asia Pacific, genomic chromosome DNA purification, restriction endonuclease digestion and the parameters for running PFGE were optimized.
RESULTSNot I digestion patterns of leptospiral genome for the Chinese representative strains were established and partial isolates of serogroup icterohaemorrhagiae from the leptospirosis surveillance in Sichuan and Anhui provinces were analyzed by PFGE. Results showed that each of all the 15 Chinese representative strains had a unique pattern. 91.67% (22/24) of the 24 isolates identified as serogroup icterohaemorrhagiae matched to the map of the reference strain 56601 (serogroup icterohaemorrhagiae serovar lai).
CONCLUSIONThe PFGE figures were clear with high resolution and the fragments were equally distributed by this standardized operating procedure so as to reveal the molecular-genetic characteristics of Leptospira interrogans. The patterns had high relativity with the serological identification and seemed to be very important for genetic analysis of strains in studying the outbreak of leptospirosis.

BACKGROUNDThioredoxin is one of the most important redox regulating proteins. Although thioredoxin has been shown to protect cells against different kinds of oxidative stress, the role of thioredoxin in myocardial ischemia and reperfusion injury has not been fully understood. This study was conducted to explore the protective role of human thioredoxin on myocardial ischemia and reperfusion injury and its potential mechanisms.
METHODSPurified human thioredoxin was injected into adult Wistar rats, which were subjected to 30 minutes of myocardial ischemia followed by 2 or 24 hours of reperfusion. We detected 1) the infarct size; 2) the level of malondisldehyde (MDA) in serum; 3) the expression of caspase-9, and cytochrome c in/out of mitochondria by Western blotting; 4) apoptosis by terminal-deoxynucleotidyl transferase mediated nick end labeling (TUNEL) assay and caspase-3 and its protein by reverse transcriptase polymerase chain reaction (RT-PCR) and Western blotting; 5) the expression of bcl-2 and bax in cardium by immunohistochemical (IHC) assay.
RESULTSHuman thioredoxin reduced myocardial ischemia/reperfusion injury as evidenced by significant decrease of myocardial infarct size (P < 0.01), notable reduction of myocyte apoptosis (P < 0.01), lower systemic oxidative stress level (P < 0.01) after reperfusion for 2 hours, and few inflammatory cell infiltration after reperfusion for 24 hours in rats. Furthermore, treatment with human thioredoxin significantly reduced the release of mitochondrial cytochrome C (P < 0.05), and inhibited the activity of caspase-9 (P < 0.05) and caspase-3 (P < 0.01 in mRNA and P < 0.05 at protein level). Meanwhile, human thioredoxin markedly increased bcl-2 expression (P < 0.05).
CONCLUSIONSThese results strongly suggest that human thioredoxin has cardioprotective effects on myocardial ischemia/reperfusion and its anti-apoptotic role may be mediated by modulating bcl-2 and the mitochondria-dependent apoptotic signaling pathway.

OBJECTIVETo explore the influence of dermal defect and fat dome structure destruction in burn wounds on the formation of hyperplastic scar.
METHODSFifty two wounds in 24 burn patients with deep partial thickness burn indicating tangential excision in the extremities were enrolled in the study, and they were divided into three groups according to the extent of exposure of dermal fat granules, i.e. A (without fat exposure), B (with little fat exposure) and C (with much fat exposure) groups. These three groups were subdivided into A1 (without grafting), A2 (grafting with razor thin skin), B1 (without grafting), B2 (with razor thin skin grafting), C1 (without grafting) and C2 (with split-thickness skin grafting) groups, with 9 wounds in each group. The dermal depth and exposure rate of the fat granules in each group were measured and analyzed by KS400 photography analysis apparatus. The follow-up conditions of the scars 6 months after operation were evaluated with Vancouver remark system by Vancouver score assessment.
RESULTSThere was obvious difference in the dermal depth and exposure rate of the fat granules among all the groups (P < 0.05 or 0.01). The fat exposure rate was positively correlated with the extent of the dermal defect (gamma = 0.554, P < 0.05). The Vancouver score in group A was lower than that in B and C groups (P < 0.05), while that in B1 group (3.714 +/- 2.498) was evidently higher than that in other groups (P < 0.01). The scar score was lowered when the wounds were grafted with the dermis with its thickness similar to the depth of the defect, The scar score was increased along with the elevation of fat exposure rate (P < 0.05).
CONCLUSIONThere was a positive correlation between the degree of dermal defect and that of hyperplastic scar after burns. The disruption of fat dome structure might also be an important factor in the scar development.

OBJECTIVE:
To retrospectively analyze the efficacy and safety of ruxolitinib therapy for children with thalassemia after unrelated or haploidentical stem cell transplantation.
METHODS:
From March 2020 to March 2021, 22 patients received successfully allogeneic hematopoietic stem cell transplantation in the Zhongshan Hospital of Xiamen University, from +30 to 100 days,those patients received ruxolitinib therapy (2.5 mg, twice daily) and all adverse reactions were observed, include aGVHD, cGVHD, CMV and EBV infection.
RESULTS:
22 patients underwent allogeneic stem cell transplantation, 5 patients were diagnosed as aGVHD, 3 patients had grade I-II skin GVHD and 2 patients had grade II intestinal GVHD, those patients were cured. All patients were followed up for more than 21 weeks, 4 cases developed cGVHD, including 3 cases of localized liver GVHD and 1 case of pulmonary GVHD, those were relieved after active treatment. 8 patients had elevated EBV copies (>3×103/ml), and 3 patients had increased CMV copies, the patients recovered after immunosuppressant and antiviral treatment. There was no CMV infection and EBV related post-transplantant lymphoproliferative disorders(PTLD), and no transplant related deaths.
CONCLUSION
Ruxolitinib can effectively reduce the incidence and severity of GVHD without affecting the hematopoietic recovery, and improve the survival status of thalassemia children after transplantation.
