Objective To investigate the useful parameters of transthoracic echocardiography (TTE) for the diagnosis of stroke subtypes in patients with acute cerebral infarction.Methods One hundred and one acute ischemic stroke patients met all of the following criteria including ≥50 years of age,normal sinus rhythm on admission,and transesophageal echocardiography (TEE) within 7 days from the onset.The clinical significance of the TEE parameters on admission was examined for identifying intracardiac thrombus formation as follows; left atrial dimension,left ventricular end-diastolic dimension,percentage fractional shortening,left ventricular mass index,ratio of the transmitral inflow velocities (E/A),and the deceleration time of the E wave.Results There were 28 patients with E/A ≥ 1.0 (70 ± 12) years old and 73 with E/A ＜ 1.0 (73 ± 10) years old.No patients showed pulmonary congestion on chest radiography.There were no significant differences in age,TTE parameters,and plasma levels of brain natriuretic peptide between the two groups.Patients with E/A≥ 1.0 had higher incidence of left atrial appendage (LAA)thrombus formation and/or spontaneous echograhic contrast than those with ＜ 1.0 (25.0％ vs 5.5％,x2 =7.95,P ＜0.01).A significant relationship was found between E/A and emptying flow velocity of the LAA (r =-0.569,P ＜0.01).Multivariate logistic regression analysis showed E/A was an independent predictor for LAA thrombus (risk ratio 1.531 per0.1 increase,95％ confidence interval 1.129-2.076,P =0.0002).Conclusions Increased level of E/A on admission was associated with the occurrence of left atrial appendage thrombus formation in patients with acute ischemic stroke.

"Prescription embodied in Preparation", Chinese medicine preparation, aims to study the specific form of Chinese medicine from raw materials to preparation for acting on patients directly. Its development has gone through three stages according to the characteristics of raw materials pretreatment, including "direct smash and initial extraction for Chinese materia medica", "Extensive extraction and preliminarily impurity for Chinese materia medica" and "Refining and purification for Chinese materia medica". With the development of new technologies and new theories, Chinese medicine preparation emerged in a new stage: structural components of Chinese medicine, with the characteristics of definited material basis, clear mechanisms, determined ADME/T properties, reasonable drug release system designs and scientific productions quality controls. This requires multidisciplinary to solve systemly the problems of Chinese medicine preparation. In this article, we reviewed the development of Chinese medicine preparation in different times, and analyzed the development and the characteristics of Chinese medicine preparation; and mainly focused on a fact that multidisciplinary promoted the study and development of Chinese medicine preparation, especially in structural components of Chinese medicine. It provides development direction and theoretical basis for Chinese medicine preparation.

To investigate the prevalence of Enterococcus faecalis in saliva and filled root canals of patients requiring endodontic retreatment for apical periodontitis. Patients with apical periodontitis who were referred for endodontic retreatment were examined. The type and quality of the restoration, symptoms, quality of obturation were recorded. During retreatment, an oral rinse sample and root canal sample were cultured using brain-heart infusion agar and bile esculinazide agar to select for E. faecalis. The 16S rRNA technique was used to identify E. faecalis. A total of 32 women and 22 men (mean age: 38 years; s.d.: 11 years) and 58 teeth were studied. The prevalence of E. faecalis was 19% in the saliva and 38% in the root canals. The odds that root canals harbored E. faecalis were increased if the saliva habored this bacterium (odds ratio=9.7; 95% confidence interval=1.8-51.6; P<0.05). Teeth with unsatisfactory root obturation had more cultivable bacterial species in root canals than teeth with satisfactory root obturation (P<0.05). E. faecalis is more common in root canals of teeth with apical periodontitis than in saliva. The prevalence of E. faecalis in root canals is associated with the presence of E. faecalis in saliva.

Objective To establish the in vivo models of adriamycin(ADR)-induced cardiotoxicity in rabbits, investigate the protective effect of oxymatrine (OMT) on ADR-induced cardiotoxicity, and explore the possible mechanism. Methods Twenty-six rabbits were randomly divided into ADR group (n=8, 2 mg/kg ADR), OMT group (n=5, 10 mg/kg OMT), ADR + OMT group (n=8, 10 mg/kg OMT was injected 30 min before ADR injection) and saline group (n=5, same quantity of normal saline), and rabbits in each group were infused with medicine or normal saline through ear marginal vein once a week for 8 weeks. The apoptosis of myocardial cells was detected by TUNEL methods, and the activity of superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px) was determined. Results After treatment, the body weight of ADR group was significantly lower than that of the other groups(P < 0.05), the activity of SOD and GSH-Px significantly decreased and the apoptosis index (AI) was significantly higher than that of the other groups(P <0.01). There were similar while minor changes in ADR + OMT group. There was no significant adverse effects in OMT group. Conclusion OMT protects heart from adriamycin-induced injury in rabbits, which may relate to the decrease in level of antioxidant and apoptosis of myocardial cells.

The 1.23 kb DNA fragment encoding the early protein EP0 of pseudorabies virus (PRV) Ea strain was amplified by PCR technique and cloned into pBluescriptII sk+.Three sequencing plasmids containing the partial fragment of the EP0 gene were constructed and the sequences were obtained by Sanger's sequencing technique. Compared with PRV InFh strain, there were multipile site-mutations and a deleted-mutation in the EP0 gene of PRV strain Ea，and the diversity of amino acid residues also existed.Then, the EP0 gene was inserted into an expression vector, pET-28a, fused into the downstream of the 6ΧHis-Tag in frame, to yield the expression plasmid pETEP0. After induction by IPTG, a high expression of fusion protein was obtained, SDS-PAGE analysis and Western blotting showed that the fusion protein was 62kD and the protein was specific to antisera against PRV Ea strain. This indicated that the EP0 gene be expressed in BL21(DE3) and the expression products have immuno-genicity.

Objective To evaluate the effects of regular follow-up and systematic management in premature infants on early discovering of cerebral palsy and intervention efficacy in early phase. Methods Fifty premature infants with cerebral palsy recruited from early children development outpatient service, were classified as treatment group; 40 premature infants with cerebral palsy recruited from general outpatient service, were classified as control group. The infants of treatment group received systematic follow-up and intervention. while the infants of control group received no systematic management. Age and therapeutic efficacy were compared between the two groups. ResultsThe average age in the treatment group ( [4. 0 ± 1.2] months) was significantly younger than that of the control group ( [7.0 ± 1.4] months) ( P ＜ 0. 05 ). The mental development index ( MDI )and physical development index (PDI) in the treatment group was 91.8 ± 10. 2 and 90. 2 ± 11.2,respectively,which were significantly higher than that of the control group(80. 2 ± 11.7 for MDI and 79. 3 ± 10. 2 for PDI)( P ＜ 0. 05 ) . Conclusion Systematic management could help discover cerebral palsy in premature infants in time and could improve physical and mental development of these infants.

AIM: To investigate the clinical effect for treating bullous keratopathy ( BK ) by anterior corneal stromal acupuncture combined with amniotic membrane transplantation.
METHODS: Totally 35 patients ( 35 eyes ) with bullous keratopathy were treated by corneal stromal acupuncture combined with amniotic membrane transplantation. All patients preoperative and postoperative underwent anterior segment OCT, corneal topography, corneal sensitivity and confocal microscopy. To observe postoperative ocular symptoms in patients with BK, recurrence of bulla, changes in corneal thickness, corneal sensitivity and changes in the organizational structure of the layers of the cornea.
RESULTS: Thirty-five were followed up for 6-18mo. The symptom of pain disappeared in 32 cases ( 91%) in the first day after operation and did not recur during follow-up. The symptom of pain relieved in 3 cases (9%) in the first day after operation and disappeared in 3 days. Corneal epithelium of 9 cases ( 26%) were all healed within 1wk, 21 cases (60%) were all healed within 2wk, and 5 cases (14%) were all healed within 3wk. Following up for 6-18mo, there was no recurrence of symptoms or bulla. A small amount of tiny bubbles in the surrounding area appeared in 2 cases after 3 and 4wk. All patients had no neovascularization, and had smooth corneal surface. The amnions of 30 cases (86%) were thinning after 2mo, partially dissolved and absorped, not seen with the naked eye after 3mo. Thirty-four cases (97%) had no changes in vision, one case (3%) was from the light to front of the manual. After 2mo, corneal sensation decreased in 30 cases ( 86%) , corneal thickness increased from preoperative 788±35μm to 940±43μm. After 12mo, corneal thickness increased to 1060±27μm. Results of confocal microscopy: after 3mo, the number density of the trigeminal nerve fibers under corneal basement membrane reduced, shallow stromal cells became into fibrotic stroma, deep stroma was more loose, and cells swelled significantly. The number of endothelial cells reduced and form swelled more obviously compared with preoperatively.
CONCLUSION: Corneal acupuncture combined with amniotic membrane transplantation can effectively control the symptoms of BK, prevent the recurrence of BK, and especially it is a simple, safe and practical way for patients with poor visual function.
