Objective To explore the titre of serum anti-phospholipase A2 receptor antibodies (anti-PLA2 R antibodies) detected by the enzyme-linked immunosorbent assay (ELISA) to provide a more specific serological index for clinical diagnosis and disease judgment of membranous nephropathy (MN).Methods Thirty-four cases of MN confirmed by kidney biopsy ,32 inpatients with autoimmune diseases ,nephrotic syndrome and renal insufficiency in the nephrology department of our hospital and 12 persons un-dergoing physical examination were selected.The serum was collected for detecting anti-PLA2 R antibodies level.Then its diagnostic performance for diagnosing MM was analyzed by combining with serum TP ,ALB ,IgG ,IgA ,IgM ,C3 and C4 indicators.Results The medians of anti-PLA2 R antibodies titres in the MN group ,disease control group and healthy control group were 22.1 ,2.0 ,2.0 RU/mL respectively ,which had statistical difference between the MN group and other two groups (P<0.05).Seventeen cases of anti-PLA2R antibodies positive were in the MN group(positive rate50% )and 17 cases were negative,the disease control group and healthy control group all were negative.Its specificity and positive predictive value were 100% ,TP ,ALB and IgG had statistical difference between the MN group with the disease control group and healthy control group (P<0.05);the relative coefficients of anti-PLA2 R antibodies with TP ,ALB and IgG ,IgA ,IgM ,C3 and C4 were in turn -0.382 ,-0.344 ,-0.502 ,-0.295 ,0.062 , 0.005 and 0.241 respectively ,anti-PLA2R antibodies were negatively correlated with TP ,ALB ,IgG and IgA(P<0.01) ,positively correlated with C4(P<0.05) and had no relation with IgM and C3(P>0.05).Conclusion Anti-PLA2 R antibodies have higher specificity for the diagnosis of MN and can serve as the necessary and specific serologic detection indicator in the patients unable to conduct renal biopsy.Quantitative detection helps to condition judgment.

Background Retinal hemorrhage in newborns is a common clinical finding,and serious retinal henorrhage resulting in poor prognosis.The factors affecting retinal henorrhage in newborns are unelucidated now.Identifying these factors is helpful for the early prevention and treatment.Objective This study was to explore the underlying maternal,obstetric,and neonatal clinical factors for degree of retinal hemorrhages in healthy full-term newborns.Methods A cross-sectional study was performed in the approval of Ethic Committee of Zhongshan City People's Hospital.A total of 1 311 full-term infants,with gestational age more than 37 weeks and Apgar ≥9 scores were included in this study.Infants with severe systemic diseases or any other eye diseases were excluded.Ocular fundus of the infants were examined with Ret Cam Ⅲ within 4 days of birth and were independently identified by 2 eye doctors.The newborns of retinal hemorrhage were divided into grade Ⅰ,Ⅱ and Ⅲ groups based on Egge criteria,and the infants without retinal hemarrhage served as the normal control group.Maternal,obstetric,neonatal parameters and general factors were analyzed and compared among different groups,and the risk factors that affected the newborns retinal hemorrhage were analyzed by logistic regression analysis.Results Retinal hemorrhage was seen in 28.30％ infants (371/1 311),and 152,116 and 103 infants were identified as grade Ⅰ,Ⅱ and Ⅲ,with the percentage of 11.59％,8.85％ and 7.86％,respectively.Among the factors that examined in the study,cord around fetal neck was the risk factor of aggravation of degree of retinal hemorrhage in newborns (OR =1.308,95％ CI:1.011-1.693,P =0.041).In the mode of delivery,spontaneous vaginal delivery appeared to be the positive factor of the incidence of retinal hemorrhage (OR=0.134,95％ CI:0.132-0.137,P＜0.001),but cesarean section was not a main risk factor.Conclusions Spontaneous vaginal delivery and cord around fetal neck are the potential risk factors for the aggravation of degree of retinal hemorrhage in full-term infants.Accordingly,infants with these risk factors should be paid more attention to prevent the progression of retinal hemorrhage.

Objective To discuss the clinical aesthetic effect of vermilion repair on cleft lips after using double-line reconstruction.Methods 68 children with cleft lip were repaired according to the principle of double-line reconstruction,and two contents including 7 projects,such as shapes of upper lips,vermilion borders of lips,vermilion shapes and lips,etc,were evaluated comprehensively within one month after operation for assessing the postoperative effect.Results 68 cases were followed up,with the follow-up rate of 100％,and 62 cases (91.2％) were satisfied with the vermilion repair.Six cases (8.8％) had a common effect of vermilion shapes after repair.In the 7 contents evaluated,satisfactory results were achieved in the projects except the relatively poor symmetry vermilion borders of lips.Conclusions The double-line reconstruction helps to improve the aesthetic effect of vermilion repair on cleft lips.

Objective To investigate the effects and the mechanisms of tissue factor pathway inhibitor（TFPI）on no-reflow（NR）after acute myocardial infarction（AMI）and reperfusion in rabbits.Methods Rabbits were randomly divided into sham operation group,saline control group and TFPI group.The model of NR after AMI and reperfusion was induced by ligating coronary artery for 60 minutes and reperfusion for 90 minutes.The expressions of interleukin-6（IL-6）,tumor necrosis factor alpha（TNF-α）and tissue factor（TF）were determined by immunohistochemistry.No-reflow area（NRA）was evaluated by thioflavine S staining.The ligation area（LA）and necrosis area（NA） were evaluated by Evans blue and triphenyltetra zolium chloride（TTC）staining.Results After 90 minutes of reperfusion,the levels of IL6 and TF in saline control group were all singnificantly higher than those of TFPI and sham operation group（P 0.05）.There was no statistical difference in the expression of TNF-α（P 0.05）.There was no statistical difference of LA between saline control group and TFPI group（P 0.05）,while NRA and NA were markedly reduced in TFPI group compared with saline control group（P 0.05,P 0.01）.Conclusion No-reflow happened after ligating coronary artery for 60 minutes and reperfusion for 90 minutes in rabbits.TFPI could reduce NRA and NA,and the thrombosis and inflammation might be involved in the mechanisms.

This paper explored the joint teaching model between universities and hospitals.Clinical practice teaching based on medical ethics was carried out,choosing academic leader of teaching and research section of medical ethics as the core and relying on ethic committee of affiliated hospital as the support.Three teaching methods were integrated:theoretical introduction-case analysis-multi-role discussion(doctor,patient's organization,medical ethic specialist),which rendered ethical teaching more practical and operational.Facing the dilemma of present hospital environment,introducing medical ethic and other human sciences into clinical practices and other medical organization was evidently a better choice than strengthening police forces in hospital.
