BACKGROUNDThe most appropriate surgical approach for patients with post-infarction left ventricular (LV) aneurysm remains undetermined. We compared the efficacy of the linear versus patch repair techniques, and investigated the mid-term changes of LV geometry and cardiac function, for repair of LV aneurysms.
METHODSWe reviewed the records of 194 patients who had surgery for a post-infarction LV aneurysm between 1998 and 2010. Short-term and mid-term outcomes, including complications, cardiac function and mortality, were assessed. LV end-diastolic and systolic dimensions (LVEDD and LVESD), LV end-diastolic and end-systolic volume indexes (LVEDVI and LVESVI) and LV ejection fraction (LVEF) were measured on pre-operative and follow-up echocardiography.
RESULTSOverall in-hospital mortality was 4.12%, and major morbidity showed no significant differences between the two groups. Multivariate analysis identified preoperative left ventricular end diastolic pressure > 20 mmHg, low cardiac output and aortic clamping time > 2 hours as risk factors for early mortality. Follow-up revealed that LVEF improved from 37% pre-operation to 45% 12 months post-operation in the patch group (P = 0.008), and from 44% pre-operation to 40% 12 months postoperation in the linear group (P = 0.032). In contrast, the LVEDVI and LVESVI in the linear group were significantly reduced immediately after the operation, and increased again at follow-up. However, in the patch group, the LVEDVI and LVESVI were significantly reduced at follow-up. And there were significant differences in the correct value changes of LVEF and left ventricular remodeling between linear repair and patch groups.
CONCLUSIONSPersistent reduction of LV dimensions after the patch repair procedure seems to be a procedure-related problem. The choice of the technique should be tailored on an individual basis and surgeon's preference. The patch remodeling technique results in a better LVEF improvement, further significant reductions in LV dimensions and volumes than does the linear repair technique. The results suggest that LV patch remodeling is a better surgical choice for patients with post-infarction LV aneurysm.

In this paper is advanced a new type of collimator-dual sieve-mesh collimator.Its principle is to use scanned electronic beam to attack 400 matrix-arranged wolfram targets of the square holes on the upper side of the main collimator and created 400 small X-ray fields sized by 10mm×10mm.These X-ray fields will leave on its center 400 smaller X-ray fields sized by 5mm×5mm after being further collimated by a sub-collimator. What's more,16 different groups of such X-ray fields can be left on the center of the same field by controlling the all-round movement of the main collimator and sub-collimator in proper order and by scanning it round by round and mesh by mesh with electronic beams.It is these ting fields groups that make up various treatment fields with different energy (Dosage).This type of collimator can replace and simplify all other present collimators on accelerators and conformal-intensity modulation radiotherapy equipments. It has advantage of reducing the costs of radio-therapy equipment and making conformal and intensity modulation radiotherapy easier to perforn.

Causes analysis of death is the most common work in forensic pathology practice. When designing problem-based learning (PBL) teaching objectives, we should take cause analysis of death as the main line and give consideration to other related issues. The selected cases should be typical ones that solve the target problems, which can fully reflect the basic theoretical knowledge of forensic pathology, and have moderate difficulty, delights and clear conclusions. The PBL course is divided into three steps. The first step focuses on providing students with case information to guide them to find out the problems that need to be solved. The second step focuses on discussing the problems and making pathological diagnoses. The third step focuses on answering the question raised at the beginning of the course. Each lesson can also be divided into several sections by which the lesson plans should be prepared. In the teaching process, performing active interaction with students, controlling the direction of classroom development, balancing student opportunities should be done well in order to make the curriculum smoothly and achieve the purpose of teaching.

OBJECTIVETo localize susceptibility loci in Chinese systemic lupus erythematosus (SLE) cohort by linkage disequilibrium mapping the genomic interval in human chromosome 16 so as to understand whether the pathogenesis of human SLE is related to chromosome 16.
METHODSFive microsatellite markers in chromosome 16 spanning from 57.79 cM to 65.1 cM were used for fluorescence based genotyping in 157 SLE families. Evidence for linkage disequilibrium was assessed using the extended transmission disequilibrium test (ETDT) program and Genehunter software. Susceptibility gene was searched in the positive locus, and real-time PCR method was used to detect gene expression.
RESULTSWith the ETDT, evidence for linkage disequilibrium of the marker D16S409 (P=0.0278) and D16S517 (P<0.0001) with SLE were found. It was observed that 271 bp allele of D16S517 was much in evidence for preferential transmission, while 277 bp allele was found to be transmitted less often than expected. Genehunter analysis is concordant with ETDT. By real-time PCR, OAZ(OLF1/ EBF-associated zinc finger protein) gene which is located in the positive locus showed higher expression in SLE patients than in normal controls.
CONCLUSIONResults reveal that 16q12 (58.46 cM) is associated with Chinese SLE. OAZ is a likely susceptibility gene in this locus for SLE.

OBJECTIVETo investigate the effect of Changtong oral liquid (CTOL) on the proliferation of cultured fibroblasts derived from normal peritoneum (NFs) and adhesive peritoneum (AFs) of rats.
METHODSTwenty male SD rats were randomized into 4 groups, including a normal serum group and 3 CTOL groups with CTOL treatment at low, medium or high doses. Serum samples were obtained from the abdominal arteries of the rats after oral treatment with CTOL for 7 days. The fibroblasts were isolated from the peritoneum by means of tissue culture, and the passage 3-8 cells were cultured with the sera of the normal control and CTOL groups for 24, 48, 72 and 96 h. MTT assay was used to observe the proliferation of the fibroblasts.
RESULTSThe dose of CTOL was inversely correlated to the absorbance but positively to the growth inhibition rates. Compared with the NFs cultured in normal control rat serum, the NFs in serum from CTOL groups showed no obviously changes in the absorbance at 24 and 48 h, but displayed significant reduction at 72 and 96 h (P<0.01). Compared with the AFs in normal rat serum, the AFs in the 3 CTOL groups all showed significantly decreased absorbance at 24, 48, 72 and 96 h (P<0.05). At the same time point, the inhibition rate of AFs in low-dose CTOL group showed no significant difference from that in the normal control group, but CTOL at a medium dose resulted in a significantly higher inhibition rate of AFs at 72 h (P<0.05). High-dose CTOL produced significant differences in the inhibition rates of AFs and NFs (P<0.05).
CONCLUSIONCTOL can inhibit the proliferation of AFs and NFs in vitro. AFs appear to be more sensitive to CTOL, which has a dose-dependent inhibitory effect of AF proliferation.
