48 h) in the IABP Group (14/19) was significantly higher than that in the Control Group (19/45) ( ? 2=4 110, P =0 043). Conclusions In the absence of prophylactic IABP, OPCAB can be safely operated on in patients with low ejection fraction.

Objective To evaluate the effects of combined induction therapy of interferon(IFN) and chemotherapy on survival of the patients with small cell lung cancer(SCLC)by meta-analysis.Methods Search all of clinical trials for addition of IFN to initial chemotherapy and single chemotherapy for induction therapy in SCLC patients in MEDLINE、EMBASE and COCHRANE Library.The references of related studies and education books of ASCO and ESMO meeting were handsearched.The quality of included trials was evaluated.Data were extracted by two reviewers independently with a designed extraction form.Revman 4.2.7 software was used for data analysis.Results The addition of IFN increased 1-year survival and response rate,but both of the results had no significant statistical difference.Conclusion IFN-chemotherapy induction treatment might not influence survival and response rate of patients with NSCLC.To resolve the problem,a series of controlled,prospective,randomized,double-blind,well-designed,multi-center trials should be performed.

Objective To investigate the learning curve of minimally invasive direct coronary artery bypass ( MIDCAB) via left anterior small thoracotomy. Methods We retrospectively reviewed results of a consecutive series of 80 patients underwent MIDCAB via left anterior small thoracotomy performed by a single surgeon.The patients were divided into 4 groups ( group A, B, C, D, n=20 in each group) according to the sequence of the operation.The left internal mammary artery ( LIMA) harvesting time, anastomosis time, total operative time, the drainage volume of the first day postoperation, mechanical ventilation time, hospital stays postoperation, in-hospital morbidity and mortality were compared.The learning curve was assessed by means of regression analysis with logarithmic curve fitting. Results The basic clinical characters were similar in all groups before the operation.The operations were accomplished successfully in all the 80 cases.No intraoperative conversion to sternotomy, death, or perioperative myocardial infarction happened.The LIMA-harvesting time in the group B, C, and D was significantly shorter than that in the group A [(53.7 ±19.2) min, (50.2 ±17.7) min, and (43.2 ±10.3) min vs.(77.0 ±30.0) min, P =0.001, 0.000, and 0.000].There was no difference between group B and C, B and D, C and D in the LIMA-harvesting time (P>0.05).The total operative time in the group B, C, and D was significantly shorter than in the group A [ (128.7 ±21.7) min, (129.0 ±33.3) min, and (112.2 ±14.5) min vs. (165.2 ±41.8) min, all P=0.000], without difference between the group B and C, B and D, C and D (P>0.05).The learning curve models were obtained: LIMA-harvesting time ( min) =113.77 -16.869 × ln ( operation number); total operative time (min)=220.281 -25.276 ×ln (operation number). Conclusion MIDCAB via left anterior small thoracotomy is safe and effective, with a learning curve of approximately 20 cases.

Objective: To investigate the relationship between blood lipid proifles and intraocular pressure (IOP) in adult subjects. Methods: A total of 1660 adult subjects received regular physical examination in our hospital from 2015-01 to 2015-09 were enrolled. The subjects were divided into 2 groups: Hyperlipidemia group,n=356 and Non-hyperlipidemia group,n=1304. Systolic, diastolic blood pressure (SBP), (DBP), IOP and serum levels of total cholesterol (TC), triglyceride (TG), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), apolipoprotein A1(ApoA1) and apolipoprotein B (ApoB) levels were measured in all subjects. SPSS19.0 software was used to study the relationship between blood lipid proifles and IOP by univariate and multivariate liner regression analysis respectively. Results: Univariate regression analysis revealed that IOP was positively related to SBP, DBP, TC, TG, LDL-C and ApoB, all P<0.05, while negatively related to HDL-C,P=0.028. Multivariate regression analysis indicated that with adjusted age, SBP and DBP, IOP was positively related to TC, TG, LDL-C, ApoA1 and ApoB, while negatively related to HDL-C, allP<0.05. ApoB level in either Hyperlipidemia group or Non-hyperlipidemia group was signiifcantly related to IOP in both male and female genders,P<0.05. Conclusion: ApoB level was most obviously related to IOP and it might be used as a predictor for IOP elevation in clinical research, while its validity should be further studied.

Objective To observe the changes of subfoveal choroidal thickness (SFCT) in diabetic patients with non-proliferative diabetic retinopathy (NPDR) and clinically significant macular edema(CSME),and then investigate diabetic SFCT and the relationship of diabetic CT with diabetic retinopathy (DR).Methods The patients were divided into 2 groups according to clinical guidelines of DR in China in 2014,including NPDR CSME + group(21 eyes) and NPDR CSME-group(36 eyes).All patients were underwent best corrected visual acuity (BCVA),intraocular pressure,axial length,slit lamp microscope,indirect ophthalmoscope,EDI-OCT examination,and mean arterial blood pressure measurement.The differences of BCVA,central retinal thickness (CRT) and SFCT between NPDR CSME + group and NPDR CSME-group were studied as well by means of using SPSS 18.0 for data statistics.Results There was no significant difference in gender,age,eye axis and intraocular pressure between NPDR CSME + group and NPDR CSME-group (all P ＞ 0.05).There was significant difference in BCVA between the two groups (P =0.001).The mean SFCT were (328.24 ± 101.92) μm in the NPDR CSME + group and (235.31 ± 66.98) μm in the NPDR CSME-group,and the difference was statistically significant (t =4.156,P=0.000).And plotting changes in CRT against changes in SFCT in patients with CSME revealed a positive correlation(r =0.473,P =0.000).Conclusion SFCT in NPDR CSME + patient is thicker than that in NPDR CSME-patient.And plotting changes in CRT against changes in SFCT in patients with CSME reveals a positive correlation.

Objective To study a improved technique by releasing the orbicularis retaining ligament in orbicularis oculi muscle supension blepharoplasty. Release of the orbicularis retaining ligament could cut off the contact between orbitomalar skin and periosteum at inferior orbital rim, and carry the point of tightening orbitomalar skin in orbicularis oculi muscle supension blepharoplasty. Methods There were 409 patients with apparent orbitmalar fold. The methods of releasing orbicularis retaining ligament and orbital septum fixation were added to improve the orbicularis oculi muscle supension blepharoplasty. Results 409 cases were treated using this method over the past 3 years. All results were satisfactory. No complications were observed. Conclusion This improved method of orbicularis oculi muscle supension blepharoplasty is useful for orbitomalar skin rolling, especially for orbitmalar fold. The release allows effective redraping and upward mobilization of the orbicularis of the lower lid and the premalar soft tissues. This method is a simple, safe and effective procedure for the correction of tear trough deformity and well-demarcated lid/cheek junction in lower eyelid belpharoplasty. It is one of the best choices for lower eyelid blepharoplasty.
