Objective To evaluate the changes of left atrial(LA)function in peripartum cardiomyopathy(PPCM)patients using two?dimensional speckle tracking echocardiography(2DSTE). Methods Totally 35 PPCM patients and 35 healthy postpartum women(control group)were en?rolled in this study. Left ventricular end?diastolic diameter(LVEDd)and LA anteroposterior dimension(LAAD)were measured. The end?diastol?ic volume(EDV)and end?systolic volume(ESV)were obtained using biplane modified Simpson′s method. Cardiac output(CO)and left ventricu?lar ejection fraction(LVEF)were also calculated. E wave and A wave of mitral valve were measured,and correspondingly E/A ratio were obtained. LA longitudinal systolic strain(SS),systolic strain rate(s?SR),early diastolic strain rate(e?SR),and late diastolic strain rate(a?SR)were ob?tained by 2DSTE. Results There was no statistical difference of E wave between the two groups(P>0.05). Compared to the normal control group, LVEDd,EDV,ESV,LAAD,E/A were increased,while CO,LVEF,A,SS,s?SR,e?SR,a?SR were decreased in the PPCM group(P<0.05). a?SR was positively correlated with A wave in patients with PPCM(r=0.775,P=0.001). Conclusion LA reservoir,conduit and booster pump func?tion were decreased during PPCM. 2DSTE can easily and accurately assess these changes of LA function.

ObjectiveTo observe the effect of acupoints stimulation with silver spike point therapy on insomnia.Methods60 patients with insomnia were randomly divided into the trial group and control group with 30 cases in each group. Patients of the trial group were treated by acupoints stimulation with silver spike point therapy and patients of control group were treated only with Clonopin. All patients of two groups were tested with Self-Rating Scale of Sleep (SRSS) before and after treatment.ResultsThe curative effect rate of the trial group was 86.6%; that of the control group was 60%; the curative effect of the trial group was superior to the control group (P<0.05). SRSS difference of the trial group pre-and post-treatment was 12.79±3.20; that of the control group was 10.1±3.89. There was also a significant difference between two groups (P<0.01).ConclusionThe silver spike point therapy has the better curative effect on insomnia than Clonopin.

Objective To monitor the distribution of pathogenic bacteria causing wound infection in trauma patients and their susceptibility to antibiotics in an effort to offer evidence for the rational clinical use of antibiotics.Methods Pathogens were identified by expressive type,but a very few was determined by the molecular methods.Micro-dilution or Kirby-Bauer method for minimum inhibitory concentration (MIC) was adopted for drug susceptibility test.Results A total of 121 species of pathogens numbering 1,257 bacterial strains were isolated from 1,066 patients.Strain number of the top 10 species accounted for 70.09％.Gram-positive cocci accounted for 48.93％ and Gram-negative bacilli for 49.72％.Among Staphylococcus aureus and epidermidis,methicillin-resistant bacterial strains accounted for 34.76％ and 71.08％ respectively,but none were resistant to vancomycin or linezolid.Enterococcus faecalis contained 6.06％ vancomycin-resistant enterococcal (VRE) and remained ＞ 90％ sensitive to teicoplanin,ampicilin and vancomycin.Enterococcus faecium contained 10.53％ VRE and remained ＞90％ sensitive to teicoplanin and ＞ 80％ sensitive to vancomycin.Baumanii contained 12.77％ multidrug resistant strains and remained ＞ 70％ sensitive to imipenem and meropenem.Baumanii/calcoaceticus complex contained 29.72％ multi-drug resistant strains and remained ＞ 50％ sensitive to imipenem and meropenem.Pseudomonas aeruginosa contained 3.73％ multi-drug resistant strains and remained ＞90％ sensitive to amikacin,meropenem,imipenem and piperacillin/tazobactam.No E.coli,klebsiella pneumoniae and enterobacter cloacae resistant to imipenem or meropenem were found.E.coli contained 69.51％ extended-spectrum β-lactamases (ESBLs)-producing strains and remained ＞ 90％ sensitive to piperacillin/tazobactam and ＞ 80％ sensitive to amikacin.Klebsiella pneumoniae contained 53.13％ ESBLs-producing strains and remained ＞ 80％ sensitive to amikacin.Conclusions Common bacteria are the leading cause of posttraumatic infection.Enterococcus faecalis and enterococcus faecium demonstrate higher susceptibility to teicoplanin; two kinds of acinetobacter demonstrate higher susceptibility to imipenem.

Objective To evaluate the feasibility, safety and effectiveness of interventional occlusion with thin waist occluder for perimembranous ventricular septal defect with pseudoaneurysm. Methods During the period from March 2008 to March 2013 at Shanghai Yodak Cardiothoracic Hospital , interventional occlusion with thin waist occluder was carried out in a total of 96 patients with perimembranous ventricular septal defect (VSD) complicated by pseudoaneurysm. The patient’s age varied from 2 years to 36 years. Before the procedure, routine left ventricular angiography and ascending aortic angiography were carried out. Left ventricular angiography and ascending aortic angiography as well as the transthoracic ultrasonography were performed immediately after the procedure to observe the therapeutic results. Follow-up checkups with transthoracic ultrasonography, EKG and chest X-ray film were conducted at one week as well as at one, 3, 6 and 9 months after the surgery were conducted. Results Successful occlusion of VSD was obtained in 93 patients, with a success rate of 96.8% (93/96). After the surgery, small amount of shunt flow was detected in 8 patients, which disappeared within 48 hours in 7 patients, and in the other one the shunt flow disappeared one month later which was confirmed by follow-up examination. After the treatment, complete right bundle branch block occurred in 4 patients, complete left bundle branch block in 5 patients, and transientⅢdegree atrioventricular block in one patient. The conduction block disappeared at the time of discharge in all patients. The left ventricular end-diastolic diameter (LVEDD) decreased from preoperative (47.5 ± 5.2) mm to postoperative (45.2 ± 5.1) mm, the difference was statistically significant (t = 18.33, P < 0.01). During the follow-up period lasting for 9 months, no delayed cardiac arrhythmia, valve damage or sudden death occurred. Conclusion For the treatment of perimembranous ventricular septal defect with pseudoaneurysm, interventional occlusion with thin waist occluder is safe and effective with excellent mid-term effect. Based on the imaging findings, including the location, shape, ruptured orifice, number of the perimembranous pseudoaneurysm as well as the distance between the pseudoaneurysm and the aortic valve, to select suitable occluder and proper occlusion site is the key to ensure a successful surgery.

Background and purpose: Solid papillary carcinoma (SPC) is an uncommon histological pattern accounting for <1% of breast carcinomas. It is a distinctive form of papillary carcinoma characterized by closely apposed expansile, cellar nodules. The present study aimed to investigate the clinicopathologic features, immunophenotype and prognosis of SPC of breast. Methods:We retrieved the data of 32 cases of SPC of the breast from pathology files, and determined the expressions of ER, PR, C-erbB-2, p63, Calponin, CK5/6, Ki-67, Syn and CgA by pathohistological observation and immunohistochemical examination. Results:All the patients were females with a mean age of 67.3 years. The clinical features were a palpable mass or bloody nipple discharge. The tumor was observed as a whitish-grey or yellowish-brown, lfeshy ifrm or soft, nodular circumscribed mass on gross examination. Microscopy showed solid and papillary area inside the capsule wall and that fine delicate fibrovascular septa were discovered amid the solid proliferation. The tumor cells were oval, polygonal, spindled or signet ring-like with abundant eosinophilic cytoplasm and contained mildly to moderately pleomorphic nuclei. Immunohistochemically, all tumor cells were strongly positive for ER and PR (++-+++), negative for C-erbB-2 and all cases were negative for CK5/6, p63 and Calponin in the cellular nodules. The positive expression rates of Syn and CgA were 68.8%and 78.2%, respectively. The average positive rate of Ki-67 in tumor cells was 7.5%(2%-20%). Twenty-seven patients were available for follow-up examination from 6 to 84 months and 25 patients were alive and disease free. One patient had tumor recurrence, and was alive after reoperation. Another patient died of the tumor metastasis. Conclusion:SPC is predominantly found in elderly females with distinctive pathological features and immunophenotype. SPC often carries an indolent clinical behavior, and even if accompanied by inifltration, very rare cases have recurrence and metastasis after resection, so its prognosis is better.

The validity of HbA1C and fasting plasma glucose(FPG)for screening of diabetes in community population was investigated.A total of 1 794 subjects from two sub-districts of Yangpu District,Shanghai,underwent a 75 goral glucose tolerance test(OGTT)and HbA1C determination.Based on 1999 World Health Organization criteria,there were 1 411 subjects with normal glucose tolerance(NGT),111 impaired fasting glucose(IFG),73 impaired glucose tolerance(IGT),33 IFG+IGT,and 166 diabetes.According to the receiver operating characteristic curve,the optimal cut-point of FPG for diagnosing diabetes was 6.15 mmol/L with sensitivity of 89.0%,specificity of 92.8%,and area under the curve of 0.959.The cut-point of HbA1C for diagnosing diabetes was 6.5% with a sensitivity and specificity of 71.1% and 80.2%.The area under the curve was 0.822.The screening model using FPG ≥6.1mmol/L and HbA1C≥6.5% had sensitivity of 66.9% and specificity of 97.0%.When the model was FPG ≥6.1 mmol/L or HbA1C ≥6.5%,the sensitivity and specificity was 96.3% and 76.7% respectively.The results suggest that both FPG and HbA1C have good value for screening diabetes in community,and FPG combined with HbA1C may further promote diagnostic efficacy.

Objective To observe the correlation between cardiac two-dimension global strain-speckle tracking imaging (2D-STI) and coronary artery disease index (CADi) scores in patients with acute myocardial infarction(AMI). Methods Eighty patients with AMI were chosen and given myocardial motion analysis using 2D-STI. The global longitudinal strain (GLS), global radial strain (GRS) and global circumferential strain (GCS) was calculated. All patients were given scoring according to CADi scores standard by coronary angiography. The correlations between 2D-STI indexes and CADi scores were analyzed. The area under curve(AUC) of the receiver operating characteristic curve (ROC) of critical coronary stenosis was calculated. Results GLS, GRS and GCS was all correlated to CADi scores (r=0.670, -0.621, 0.525, all P < 0.01). The sensitivity, specificity and AUC of GLS for critical coronary stenosis was 82.35%, 80.43% and 0.831. The sensitivity, specificity and AUC of GCS for critical coronary stenosis was 76.47%, 76.09% and 0.797. The sensitivity, specificity and AUC of GRS for critical coronary stenosis was 97.06%, 78.26% and 0.880. The AUC of GLS and GRS was larger than that of GCS, and the sensitivity, specificity for critical coronary stenosis was larger. Conclusions 2D-STI indexes have correlation with CADi scores. GLS and GRS has correlation with coronary artery stenosis.

AIM:To be one of the primary cause injury to multiple sites of ocular of glaucoma which affects over 70 million people worldwide. We applied data mining techniques, linear and the matrix operations, efficiently calculated the network and estimated the possible function of the“node” genes of the retina and optic of glaucoma, in order to provide new thought and method on the pathogenesis of glaucoma.
METHODS: The data in this study is from Gene Expression Omnibus ( GEO ) which belong to Nation Center for Biotechnology Information ( NCBI) , the quality of the raw data CEL files was processed and analyzed by the Expression software which belong to Affymetrix Inc. , Santa Clare, CA, USA. Significant analysis method ( SAM) which base on the T test was used to identified the significant genes. Based on GRNInfer and Gvedit soft we set up gene networks of optic and retina of mice and further more enriched analysis which based on DAVID and MAS3. 0 online software were processed.
RESULTS:The analysis between the group of the optic nerve heads and retinas in different stage of glaucoma showed that the amount of significant different expressed genes in the optic never head group increased significantly comparing with the group of retina in the early stage of glaucoma, the analysis of the genes network construction show that:the node genes of optic nerve heads included Unc13c、Kif5a、TRPM1、PANX; and the node genes of retina include POU4F1, NEFL, BC03870, CALB2. Metabolic pathways enrichment analysis which based on MAS3. 0 online platform show that there was mainly the amyotrophic lateral sclerosis, tyrosine metabolism, melanogenesis, Nitrogen metabolism, Gap junction, Leukocyte transendothelial migration metabolism pathway enriched out in optic nerve head; and there was mainly amyotrophic lateral sclerosis, neurodegenerative disorders, prostate cancer, leukocyte transendothelial migration metabolism pathway enriched out in retina.
CONCLUSION:By understanding bioinformatics result, it seems optic were more sensitive than the retina to high intraocular pressure, and weather high expression of TYrp1 gene can be as a sensitive diagnostic item require more evidence back up. Functional enrich analysis of node gene showed that cytoskeleton reconstructed, molecular motor and nutrients transport function improve in optic; and in retina, the most prominent finding in retina was enrichment function modules were focus on regeneration, repairing and differentiation of cells, which remind that we should reinforce research on reparation of retina of primary glaucoma. Metabolic pathways enrichment analysis show that inflammatory response plays prominent place in optic and retina of primary glaucoma, because of the optic narrow and crowed anatomic shape, nutrient metabolism and substances transfer enrichment modules play an important role in optics of primary glaucoma.
