Objective To explore the perioperative experiences of congenital heart disease in infants.Methods From Jan.2000 to Aug.2006,109 patients with congenital heart disease were operated in our department,their clinical data were retrospectively collected and analyzed.The patients′ age ranged from 31 days to 3 years old (13.6 months).The body weight ranged from 2.1 to 16 kg (8.6 kg).Ninety-three patients were operated under hypothermic anaesthesia with cardiopulmonary bypass(CPB).Sixteen patients underwent deep thermal and low flow CPB.Ultrafiltration was used in 62 patients.Results There were 8 deaths and the operative mortality was 7.3%,4 cases caused by low output syndromeclos(LOS),3 cases caused by pulmonary hypertension and 1 case caused by lung intection.The morbidity was in 25 cases(22.9%),the main complications were LOS in 6 patients and respiratory complications in 18 patients,hydropericardium in 1 case,respectively.Conclusion To improve the operative and CPB technique,and to improve the skills of the postoperative managements of LOS and respiratory complications are the main points in the success of the cardiac operation in infants.

OBJECTIVE: To assess the patterns of linkage disequilibrium (LD) of 16 STR loci on X chromo- some and investigate the genetic stability. METHODS: Genomic DNA samples extracted from blood stains from 500 unrelated individuals and 885 lineage members from Eastern Chinese Han population were genotyped through multiplex amplification using IDtyperX-16 kit by our independent research followed by capillary electrophoresis. LD was assessed by PowerMarker v3.25 software and mutation rate of every locus was analyzed. RESULTS: LD were not found at the 16 X-STR loci. Allele mutations were observed at 10 loci. Among them, mutation rates of DXS6809 and DXS7132 were both up to 0.0048. CONCLUSION When the 16 X-STR loci included in IDtyperX-16 kit were used for parentage testing, product princi- ples can be applied to calculate the likelihood, but mutation should be taken into consideration in the case that the genotypes do not meet the genetic law (especially at DXS6809 and DXS7132).

Objective Matrix-assisted laser desorption ionization-time of might-mass spectrometry (MALDI-TOF-MS) was utilized to analyze the protein fingerprint in brain-gut interaction of irritable bowel syndrome (IBS) model rats' colon, so as to find the clues for IBS. Methods Fourteen healthy male adult Wistar rats were selected and divided into a control and a chronic and acute stress ( CAS) group. Colon motility, visceral sensation and behavior changes of rats were detected to evaluate the model. MALDI-TOF-MS was used to observe the overall view of protein in colon so as to study whether there are abnormalities of protein levels in IBS. Results As compared with those in the control group, the number of fecal pellets [ (6. 00 ± 1. 69 ) pellets/1 h vs ( 1. 14 ± 0. 69 ) pellets/1 h, P < 0. 01 ] and frequency of abdominal contraction induced by colorectal distention (CRD) increased, while the amount of weight gain [ (298. 88 ± 18.61)gvs (348. 00±12. 44)g, P<0.01] and consumption of sucrose solutions [ (13. 63 ± 1. 69) ml/1 h vs (19.00±3.06) ml/1 h, P<0.05] decreased in the CAS group (P <0. 05). As far as protein/peptide quality different peak was concerned, CAS rats had 12 different peaks compared with the control rats. The different proteins could be divided into 4 types, which were related to iron secretion, protein synthesis, G protein system and immunity. The protein levels of the model group were higher than those in the control group (P < 0. 05). Conclusions The CAS rats integrate the major characteristics of IBS such as altered colon motility, higher visceral hypersensitivity and psychiatric disorder and can mimic the brain-gut interaction of IBS partly. The detection of differential proteins provides reference for the pathogenesis and treatment of IBS.

OBJECTIVE To survey the antibiotic susceptibility of Pseudomonas aeruginosa and medical treatment among the aged patients suffering from underlying disease.METHODS A total of 326 strains of P.aeruginosa were isolated among the aged patients with underlying disease by sputum culture.Drug susceptibility was performed and effective antibiotic treatment was given.RESULTS Amikacin(8.0%),imipenem(12.0%) and piperacillin/tazobactam(16.0%) could be chosen.The symptom of 326 patients was alleviated after clinical treatment,while some sputum samples were found still positive.CONCLUSIONS Combined use of two kinds of medicines may produce better effects in the patients with underlying disease,who infected with P.aeruginosa,but sputum should not be emphasized to converse negative in this case.

Objective To explore the early diagnosis of Alport′s syndrome(AS).Methods Renal and skin biopsy was carried out in 5 patients who manifested with isolated hematuria and nephritic syndrome(NS).By using indirect immunofluorescence method,the expression of type Ⅳ collagen ? chains was detected on epidermal basement membrane(EBM) and glomerular basement membrane(GBM).Results ?_1 chains on EBM and GBM were expression in all patients,but ?_5 chains on EBM and ?_3,?_5 chains on GBM form 2 female patients were segmental expression.Thus the goal for early diagnosis was achieved.Conclusions ? chains for EBM type Ⅳ collagen and GBM type Ⅳ collegan should be investigated if condition permits for those patients with isolated hematuria,NS(steroid-resistant) and thinned GBM in electron microscopy.It can be useful for diagnosis and differenial diagnosis of AS.

Background and purpose:Neoadjuvant chemotherapy is one of the hot studied area in breast cancer research.Our aim was to explore the relationship between the clinical effect,pathological changes and the neoadjuvant chemotherapy containing THP and docetaxel on breast cancer.Methods:The expression of ER, PR and CerbB-2 in breast cancer tissue of patients who had received neoadjuvant chemotherapy were detected by immunohistochemistry method.The relationship of age,ER,PR,CerbB-2,pathological stage and axillary lymph node metastasis with pathological complete response(pCR) was analysed.Results:For the patients after neoadjuvant chemotherapy,the pCR of the positive ER(0%),PR(9.38%) was lower than that of negative ER(20.27),PR(90.63%) respectively.The pCR of the positive CerbB-2(33.33%) was higher than that of negative CerbB-2(9.74%,P
