0.05), but hospitalization duration was shorter in the invasive group than in the conservative group (10.3?5.6 days vs 14.6?10.7 days, P

50% and was classified as in-stent if inside stent or in-segment if located within the stented segment plus the 5 mm segments distal or proximal to the stent margins. Results Among the 8 patients included in this analysis, 5 had in-segment restenosis and 3 had in-stent restenosis (2 were not real in-stent restenosis and were just due to underexpansion). IVUS showed all restenosis occurred as localized lesion. Conclusion Restenosis after drug-eluting stents implantation is frequently associated with local trauma outside the stented segment and incomplete lesion coverage by the drug-eluting stent. Restenosis usually occurs proximal to the stent and presents as a localized lesion.

OBJECTIVE:To investigate the clinical efficacy of levodopa combined with comprehensive therapy for ametropic amblyopia children and teenagers and its effeets on pattern visual evoked potential(P-VEP)and visual function. METHODS:70 pa-tients(80 eyes)with ametropic amblyopia were randomly divided into observation group(35 cases,40 eyes)and control group(35 cases,38 eyes). Control group received comprehensive therapy as wearing correctional glasses,occlusion therapy and visual stimu-lation training;observation group additionally received levodopa 0.125(d1-3)-0.25 g/time,bid,on the basis of control group for 6 months. Therapeutic efficacy,P-VEP,Visual sensitivity and visual function were compared between two groups,and the occur-rence of ADR was recorded. RESULTS:The effective rate of observation group(92.50%)was significantly higher than that of con-trol group(76.32%),with statistical significance(P<0.05);the wave amplitude of P-VEP P100 in observation group were signifi-cantly greater than in control group,and the incubation period was significantly shorter than control group,with statistical signifi-cance(P<0.05);visual acuity under different spatial frequency contrast were significantly higher than control group,and correc-tion convergence range and correction separation range of observation group were significantly greater than those of control group, while corrected near stereo vision was significantly less than control group,with statistical significance (P<0.05). There was no statistical significance in ADR incidence between 2 groups (P>0.05). CONCLUSIONS:Levodopa combined with comprehensive therapy can improve the function of visual central neurons,and improve visual acuity and binocular stereo vision functions so as to improve therapy efficacy.

Objective To explore the effects of residual renal function (RRF) on quality of life (QOL) in patients with continuous ambulatory peritoneal dialysis (CAPD),and analyze the factors influencing QOL.Methods One hundred and eighteen patients treated with CAPD for at least 3 months in No.455 Hospital of People's Liberation Army were enrolled.All patients were divided into two groups according to residual glomerular filtration rate (rGFR):the group with RRF [rGFR≥ 1 ml·min-1 · (1.73 m2)-1],and the group without RRF [rGFR ＜ 1ml · min-1 · (1.73 m2)-1].The demographic characteristics,laboratory data,cardiothoracic ratio,dialysis adequacy parameters,rGFR,blood pressure,urine volume,ultrafiltration volume and dialysis prescription were investigated.Patient's QOL was evaluated by Medical Outcomes Study 36-Item Short-Form Health Survey (SF-36).Results There was no significant differences between the groups with and without RRF in the age,gender,causes of disease,complication,body mass index (BMI),systolic blood pressure (SBP),diastolic blood pressure (DBP),haemoglobin (Hb),cholesterol,triglyceride,high-density lipoprotein,low-density lipoprotein,normalized protein catabolic rate (nPCR) and cardiothoracic ratio (all P ＞ 0.05).Compared with the patients with RRF,PD duration,ultrafiltration volume,serum creatinine (Scr),calcium,phosphorus,C-reactive protein (CRP),parathyroid hormone (PTH) and peritoneal dialysis dose in the patients without RRF were significantly higher,and urine volume,serum albumin (Alb),potassium,and urea total Kt/V were significantly lower (all P ＜ 0.05).The patients without RRF had a significantly lower score in physical function and physical component summary as compared to the patients with RRF (all P ＜ 0.05).There was no significant differences in role physical,bodily pain,general health,vitality,social function,role emotional,mental health,mental component summary and SF-36 scores (all P ＞ 0.05).Simple linear regression showed that there was no correlation between rGFR and SF-36 scores (β=1.330,P=0.070).Multiple linear regression revealed that SF-36 scores were correlated with CRP (β=-0.477,P ＜ 0.001),Scr (β=0.020,P ＜ 0.001),cardiothoracic ratio (β=-57.823,P=0.004),Alb (β=0.772,P=0.016) and ultrafiltration volume (β=-0.006,P=0.031),but not correlated with rGFR (β=0.099,P=0.302).Conclusions PD patients without and with RRF perceived different scores in physical health,but their scores were similar in mental health and QOL.RRF was no related to QOL in PD patients.Chronic inflammation,fluid overload and malnutrition were the main factors that affect QOL.

Objective To observe the changes of CD4+CD25+ regulatory T cells, Foxp3 mRNA and soluble interlukin 2 receptor (sIL-2R) in the peripheral blood of kidney transplantation recipients and to evaluate their effect on the diagnosis of acute rejection. Methods Forty-two renal transplant recipients and 30 healthy controls were enrolled in this study. CD4+CD25+ regulatory T cells proportion, Foxp3 mRNA and sIL-2R of pre-transplantation and those of day 7,14, 28, 56 of post-transplantation were measured by flow cytometer, fluorescent quantization PCR and enzyme-linked immunosorbent assay (ELISA), respectively. Biochemistry appliance was used to detect serum creatinine. The diagnosis of acute rejection in transplanted kidney was based on the clinical symptoms, the laboratory examinations, Doppler ultrasound and biopsy. Results (1)At day 7, 14, 28, 56 of post-transplantation, CD4+CD25+ regulatory T ceils proportion, Foxp3 mRNA level in acute rejection group were significantly decreased compared with those in non-acute rejection group. (2) There were significant differences of peripheral blood CD4+CD25+ regulatory Tcells[(9.22±3.53)% vs (6.09±1.99)%, P<0.01], Foxp3 mRNA[(0.82±0.36)×10-3 vs (0.50±0.28)×10-3, P<0.01] and sIL-2R levels [(856.30±108,24) U/ml vs (247.35±11.24) U/ml, P<0.01]between patients of pre-transplantation and healthy control group. (3)Plasma CD4+CD25+ regulatory T cells [(16.53±4.14)%] and the expression of Foxp3 mRNA [(4.97±1.94)×10-3] was significantly increased, but sIL-2R level [(463.72±31.23) U/ml] was significantly decreased as the transplanted renal function was restored (all P<0.01). (4) Plasma CD4+CD25+regulatory T cells [(12.18~2.86)%] and the expression of Foxp3 mRNA [(3.15±1.22)×10-3] was significantly decreased (P<0.01), and sIL-2R level [(748.36±115.41) U/ml] was significantly increased (P<0.01) when acute rejection occurred. The above changes had an earlier onset than the change of Scr. (5)The percentage of CD4+CD25+ regulatory T cells was positively correlated with the Foxp3 mRNA level (P<0.01), but was not correlated with sIL-2R level in all the patients. Conclusion The measurement of these markers in peripheral blood may be an important guideline to the diagnosis and prognosis of acute rejection in renal transplant recipients.
