Objective To review the experience of OPCAB and plication of left ventricular aneurysm. Methods Without cardiopulmonary bypass, heparin was given at 1.0～1.5 mg/kg.The 2-0 Surgipro 843 sutures were placed across the base of aneurysm using a strip of teflon felt on either side. The suture line was oriented to reconstruct a relatively normal left ventricular contour. Concurrent CABG was performed. Results 46 cases were reviewed. Left internal mammary artery (LIMA) grafts to the LAD were performed in 39 cases, off-pump with cardiopulmonary bypass in 3, IABP were used in 2. One patient died of left ventricular dysfunction. The other patients had no new myocardial infarctions and were discharged 10 to 14 postoperative days. Conclusion OPCAB and plication of left ventricular aneurysm could obviously decrease the risk of cardiac rupture and avoid the complications of cardiopulmonary bypass.

Background Clinical researches showed that antimicrobial-resistance of bacterium is gradually serious.It is very important to master pathogen distribution and antimicrobial susceptibility after eye surgery.Objective This study was to investigate the distribution and drug sensitivity of pathogenic bacteria from ocular operative infection in 3-year duration to provide a reference for reasonable selection of antibiotics.Methods Sixtyfive positive specimens were obtained from 65 patients due to postoperative infection in Department of Ophthalmology of Shenzhou Hospital and Shengjing Hospital from 2009 January through 2011 December.The pathogenic bacteria were isolated and then the drug sensitivity test of conventional antibiotics was performed.Results Among the 65 ophthalmic specimens,35 strains of Gram-positive bacteria were isolated with the constituent ratio 53.8％,and 15 strains of Gram-negative bacteria accounted for 23.1％.Fungus was found in 15 cases with the constituent ratio 23.1％.Staphylococcus epidermidis accounted for 42.9％ in Gram-positive bacteria,and Pseudomonas aeruginosa accounted for 33.3％ in Gram-negative bacteria.Aspergillus was the main component of fungus,which accounted for 60.0％ of the proportion 3 strains of methicillin-resistant Staphylococcus aureus (MRSA) in 8 strains of Staphylococcus aureus,but no vancomycin-resistant Enterococcus (VRE) and vancomycin-resistant Staphylococcus (VRS) were seen.The in vitro drug sensitivity test showed that the main Gram-positive bacteria,Staphylococcus epidermidis and Staphylococcus aureus,were sensitive to linezolid,vancomycin,levofloxacin and ciprofloxacin with the sensitive rates ＞50.0％,and these bacteria were lowly sensitive to penicillin and erythromycin with the sensitive rates ≤30.0％.Pseudomonas aeruginosa appeared to be the main Gram-negative bacteria,showing a sensitive rate ≥ 80.0％ to tobramycin,amikacin,ceftazidime,cefepime,cefoperazone/sulbactam,piperacillin/tazobactam,imipenem and meropenem.Conclusions Staphylococcus epidermidis,Staphylococcus aureus,Pseudomonas aeruginosa and Aspergillus are primary pathogens in ocular infection after operation.Antibiotics such as penicillin,erythromycin,levofloxacin,cefotaxime seem to be relatively high resistant to eye infection.To choose sensitive antibiotics timely and reasonably is a key to the prevention and control of ocular infection after operation.

ObjectiveTo investigate the therapeutic effect of genciclovir on cytomegalovirus (CMV) infection of children with cerebral palsy (CP).Methods36 CP children with CMV infection were randomly divided into treatment group and control group with 18 cases in each group. Children of treatment group were treated by genciclovir with 5 mg/kg i.v. drip q l2 h for 14 days at inductive phase and 7.5 mg/kg i.v. drip qod for 6 weeks at maintain phase. Cases of control group were treated by acyclovir with 5 mg/kg i.v. drip q 8 h for 14 days at inductive phase and 7.5 mg/kg i.v. drip q l2 h for 6 weeks at maintain phase. CMV-DNA contents in urine of two groups were measured before and after treatment.ResultsCMV-DNA contents in urine of two groups were not different before treatment (P>0.05). For control group, CMV-DNA contents were also not different before and after treatment. For treatment group, CMV-DNA contents after treatment significantly decreased compared with pre-treatment and that of control group after treatment (P<0.05).ConclusionGenciclovir is effect and safety for CMV infection of CP children.

ObjectiveTo investigate whether the Toxoplasma infection is the risk factor of occurrence of children cerebral palsy.Methods236 children with cerebral palsy and 428 normal children were included. Children were laminated to 4 groups by age:-3 months,-6 months,-9 months,-12 months. Final diagnosis was made by one or more finding following: plasma Toxoplasma DNA(TOX-DNA), plasma Toxoplasma circulating antigen(TOX-CAG), plasma Toxoplasma IgM(TOX-IgM), exclusion other congenital infected diseases.ResultsThe OR and 95%CI were 10.13,3.74-27.42 in -3 months,7.71,2.45-24.28 in -6 months,8.84,1.85-42.31 in-9 months(P<0.01 respectively), and 4.30, 0.83-22.28(P>0.05)in -12 months. ConclusionThere is correlation between the Toxoplasma infection and the children cerebral palsy; the earlier Toxoplasma infection, the greater the risk of cerebral palsy. Congenital Toxoplasma infection may be one of important factors in children cerebral palsy.

BACKGROUND:In oral warm and moisture circumstance, al oy which contains Be is easily to be eroded to release Be2+. But there is stil no research focusing on beryl ium influence on genotype of Porphyromonas gingivalis fimbriae gene cluster. OBJECTIVE:To investigate Be 2+effect on genotype of Porphyromonas gingivalis fimbriae gene cluster. METHODS:The revived Porphyromonas gingivalis was resuscitated for 48 hours in the anaerobic culture medium with different concentration of Be 2+(10×10-6, 5×10-6, 1.25×10-6). Through PCR amplification and sequencing, we investigated the effects of Be2+RESULTS AND CONCLUSION:(1) When Be on genotypes of Porphyromonas gingivalis fimbriae gene cluster. 2+concentration was 5×10-6, we found the peak of 217 and 257 sites on DNA sequence expressing G/A overlap peak, different from G single peak of the other groups, suggesting the suspicious bases changes, part of the single base G mutated into A. (2) On al concentrations, we found a base group composed of seven A bases was inserted into the 101 site of DNA sequence. Up to now, there is no direct contacts of the mutations occurring to Be2+concentration. Changes of gene may lead to the shifting of the reading frame, the abnormal synthesis of proteins, the change of Porphyromonas gingivalis fimA gene toxicity, and lastly the unbalance of the micro-ecological environment.

AIM:To compare the efficiency of fibrin glue to suture technique in pterygium surgery performed with limbal autograft under different methods of anesthesia.
METHODS: A prospective randomised clinical trial was carried out in 60 eyes of 55 patients operated for primary nasal pterygium, which were divided into two groups randomly: experimental group ( 30 eyes in 27 patients ) was under surface anesthesia ( oxybuprocaine ) and control group ( 30 eyes in 28 patients ) was under local anesthesia ( 20g/L lidocaine ). Autologous limbal graft taken from the superotemporal limbus was used to cover the sclera by a fibrin tissue adhesive after pterygium excision. Patients were followed up at least for 6mo. Time of operation, matching degree of graft and VAS score were mainly observed and recorded.
RESULTS: In experimental group the average surgery time was shorter (P=0. 008) and matching degree of graft ( 93%) was better than control group ( 83%) , the differences had statistical significance(P<0.05).
CONCLUSION: The surface anesthesia is enough when using fibrin glue for graft fixation in pterygium surgery, which will shorten surgery time and get better matching degree of graft.

Background Small incision lenticule extraction (SMILE) is increasingly applied in the correction of myopia and astigmatism.However,the early clinical outcomes of SMILE for different refractive myopia and astigmatism is seldom reported.Objective This study was to investigate the safety,efficacy,predictability and early stability after SMILE in low,moderate and high myopia.Methods A series of cases-observational study was carried out.A total of 195 eyes of 108 myopic patients were enrolled in Tianjin Eye Hospital from May to December 2012 under the informed consent.The patients were divided into the low (≤-3.00 D),moderate (＞-3.00 to-6.00 D) and high myopia (＞-6.00 D) groups according to different diopters,with 57 eyes,76 eyes and 62 eyes,respectively.SMILE was performed on all the eyes.The uncorrected visual acuity (UCVA)(LogMAR),best corrected visual acuity (BCVA) (LogMAR),equivalent sphere (SE),intraocular pressure,anterior segment and corneal topography were examined before operation and 1 day,1 week,1 month and 3 months after operation to evaluate the effective index (postoperative UCVA/preoperative BCVA),safety index (postoperative BCVA/preoperative BCVA),predictability and early stability of SMILE.The linear regression analysis was used to analyze the relationships between the attempted refraction and the achieved refraction postoperative 3 months in three groups.Results The percentage of UCVA (LogMAR)＜0.1 was 100％,97.1％ and 92.8％ in the low,moderate and high myopia group,respectively in 3 months after SMILE.The postoperative BCVA of all the operated eyes reached preoperative one.The residual SE was (-0.07±0.16),(-0.05 ±0.20) and (-0.08±0.27)D in the low,moderate and high myopia group,respectively in 3 months after SMILE.The percentage of residual SE±0.5 D was 100％,98.7％ and 93.6％ in the low,moderate and high group,and that of SE±1.0 D was 100％ in all of the groups.The postoperative corrected SE was gradually increased with the raise of predicted SE in the low,moderate and high myopia groups (r=0.942,0.959,0.957,all at P＜0.001).Conclusions SMILE is safe,effective,predictable and stable for the correction of low,moderate and high myopia.The corneal wound healing was slightly slower in the low myopia group than that in the moderate and high group.A slight regression of myopic power appears in high myopia eyes 3 months after SMILE.

Background The relationship between corneal central thickness (CCT) and corneal biomechanical property does not reflect the effective amount of ablated tissue because CCT measures only the change in a single point.Corneal volume (CV) is a representative parameter of corneal morphology,and it can fully reflect corneal thickness and tissue distribution.Objective This study was to investigate the correlation between volumetric corneal changes and corneal biomechanical properties after small incision lenticule extraction (SMILE).Methods A prospective series cases-observational study was carried out.This study protocol was approved by Ethic Committee of Tianjin Eye Hospital,and written informed consent was obtained from each patient prior to entering the cohort.Sixty-seven right eyes of 67 myopia or myopic astigmatism patients who received SMILE in Tianjin Eye Hospital from June 2014 to July 2015 were included in this study.Before and 3 months after surgery,the CV at 3,3-5,5-7 and 7-10 mm (CV3,CV3-5,CV5-7,CV7-10) was measured by Pentacam anterior segment analysis system,and corneal hysteresis (CH) and corneal resistance factor (CRF) were obtained by ocular response analyzer (ORA).The changes of CV (ACV),CH (ACH) and CRF (ACRF) were calculated,and the correlations between ACV and ACH or ACRF were analyzed.Results CV3,CV3-5 and CV5-7 values after SMILE were significantly lower than those before SMILE (t =36.24,20.38,16.17,all at P＜ 0.001).The CH values before and after SMILE were (10.06± 1.11) mmHg and (8.10± 1.05) mmHg (1 mmHg =0.133 kPa),and the CRF values before and after SMILE were (10.40 ± 1.38) mmHg and (6.91 ± 1.19) mmHg,respectively,showing significant reduces after SMILE than before SMILE (t =16.71,27.41,both at P＜0.001).Positive correlations were seen between the CV values at different corneal areas and CH value or CRF value.Moderate positive correlations were found between CV3 and CH or CRF (r =0.571,0.569;both at P＜0.001) before surgery,and 3 months after surgery,a weak positive correlation was seen between ACV3 and ACH (r =0.394,P ＜ 0.001) or a moderate positive correlation between ACV3 and ACRF (r=0.501,P＜0.001).Conclusions The CV value is gradually increased from the central cornea to periphery cornea.The CV change is associated with CH and CRF changes after SMILE,and CV3 probably is a useful parameter for the evaluation of corneal biomechanics after refractive surgery.

Objective To explore the regional homogeneity (ReHo) feature of the spontaneous neural activity within young male depressed patients,and conduct correlation analysis of the abnormal regions with the severity of depressive symptoms.Methods 19 male depressed patients and 19 educated age-matched male healthy controls were undergone resting-state functional magnetic resonance imaging scanning at 3.0 Tesla.The whole brain' s regional homogeneity was calculated.The ReHo values of abnormal brain regions after alphasim correction were conducted correlation analysis with the total score of Hamilton Rating Scale for Depression.Results As compared with the controls,the depressed patients exhibited significantly increased ReHo in the bilateral parahippocampal (-30,-42,-9:K=43:27,-33,-12:K=18) and the right posterior cingulate gyrus(3,15,33:K=54),while decreased ReHo in the right postcentral gyms (27,-36,54,K =21) (P＜0.05,Alphasim).The correlation analysis showed that the ReHo of the right parahippocampal gyrus was positively correlated with the HAMD17 total scores (r=0.535,P=0.018).Conclusions The male depressed patients exhibit abnormities in the limbicrelated brain regions during rest,and the extent of damage is correlated with the severity of depression.
