BackgroundThe neutrophils infiltration and vascular endothelium damage are found in the patients with diabetic retinopathy (DR).Calprotectin existes in the cytosol outside lysoome.It is thought to be a marker of inflammation.The effect of calprotectin in the development of DR is still in the study. Objective This study was to investigate the contents of plasma calprotectin in different stages of DR in patients with type 2 diabetes mellitus. Methods This was a case-control study.Sixty consecutive patients with type 2 diabetes mellitus were enrolled in this study.The patients were assigned to non-DR (NDR) group,non-proliferative DR (NPDR) group and proliferative DR (PDR)group according to fundus appearance and fundus fluorescein angiography(FFA) manifestation and 20 patients for each group.Twenty healthy subjects matched in gender,age and blood biochemical indicators were collected as the normal control group.The periphery blood samples were collected from the subjects for the detection of plasma calprotectin by ELISA.The plasma calprotectin levels were compared among different stages of DR and normal subjects.All subjects had signed informed consents.Results The contents of plasma calprotectin were (57.70±12.29 ),( 72.07± 10.14 ),( 87.70 ± 10.37 ),( 94.36 ± 9.40 ) ng/L in the normal control group,NDR group,NPDR group,PDR group respectively,with a statistically significant difference among 4 groups (F =73.09,P＜0.001 ).The content of calprotectin in PDR group showed a highest value in comparison with normal control group,NDR group and PDR group(q =20.157,10.648,4.497,P＜0.01 ).The content of calprotectin in NPDR group was significantly higher than that in NDR group( q=6.216,P＜0.01 ). ConclusionsPlasma calprotectin may play a role during the development of DR in type 2 diabetes mellitus patient.

Jaundice can occur in most neonates.Most jaundice is benign,but beacuse of the potential toxicity of bilirubin,newborn infants with severe hyperbilirubinemia can develop acute bilirubin encephalopathy or kernicterus.In October 2004,American(academic) of pediatrics produced the latest guideline for newborn jaundice aim to reduce the incidence of acute bilirubin encephalopathy or kernicterus and avoid unnecessary costs or treatment.The latest guideline emphasizes the important of successful breastfeeding,time of jaundice developed,assessment for the risk of severe hyperbilirubinemia,close follow-up,and prompt intervention when indicated,provide a framework for the prevention and management of hyperbilirubinemia in newborn infants of 35 or more weeks of gestation.Some new view in the latest guideline may be helpful to us.

This article reported the treatment of 3 cases of frequent recurrent intractable nephrotic syndrome by XIE Chang-sen. On basis of the therapeutic method of invigorating the spleen and kidney, other methods should be used according to individual difference and special clinic signs and symptoms, such as other invigorating qi and consolidation of superficies, nourishing blood and dispersing stagnated liver qi, warming kidney qi to invigorate yang, replenishing essence and dispersing turbid and so on. And partner treatment is the key for cure.

Objective To analyze the clinical features and causes of benign paroxysmal positional vertigo(BPPV).Methods The clinical data of 521 patients with BPPV were collected.The percentage of patients with BPPV in all the outpatients with dizziness and vertigo,the clinical characteristics of BPPV,and the prevalence of comorbidity with migraine were analyzed.Results BPPV accounted for 35.7% of patients with vertigo and 12.1% of patients with dizziness.Among the 521 patients with BPPV,158(30.3%)were male and 363(69.7%)were female,with an average age of(57.5?12.8)years old(20 to 93 years old).Right semicircular canals were involved in 323 cases(62.0%),and left semicircular canals in 187 cases(35.9%).The latency period of nystagmus of vertical canals was(3.22?2.37)s,and time of persistence was(8.31?7.98)s.The latency period of nystagmus of horizontal canals was(2.33?1.50)s,and the time of persistence was(14.77?11.40)s.There were significant differences in the latency period of nystagmus and time of persistence between the vertical and horizontal canals(P=0.001 and P=0.000).Fifteen patients(2.9%)had a history of head trauma and 39(7.5%)were complicated with migraine.Conclusion BPPV is prevalent in patients with dizziness and vertigo,and misdiagnosis and missed diagnosis should be avoided.

Objective To evaluate the effects of ulinastatin on acute lung injury during ortho- topic liver transplantation(OLT).Methods Twenty ASAⅢ-Ⅳpatients with end-stage liver disea- ses.undergoing OLT were randomly divided into two groups.Ulinastatin group received intravenous infusion of ulinastatin(3?10~4 IU in 100 normal saline)after skin incision and every 4 h thereafter(n =10).Control group received same amount of normal saline instead of ulinastatin(n=10).Blood sam- pies were taken before skin incision,120 min after skin incision,30 min after liver was removed,5 min and 60 min after reperfusion of the graft and at the end of operation for determination of plasma IL-6, IL-8,TNF-?,MDA concentrations and SOD activity.Respiratory index(RI)[P_(A-a)DO_2/PaO_2]was cal- culated before skin incision,30 min after liver was removed,5 min and 60 min after reperfusion of the graft and at the end of operation.After anesthesia was induced,cardiac output,mixed venous oxygen saturation and central venous temperature were continuously monitored during operation.ECG,CVP, SpO_2,P_(ET)CO_2,radial artery and MPAP were also continuously monitored during operation.P_(ET)CO_2 was maintained at 35-40 mm Hg during operation.Blood temperature was maintained above 35.5℃during operation.Results In group C plasma IL-6 and IL-8 concentrations were significantly increased from 120 min after skin incision to the end of operation as compared with the baseline values(P0.05).RI was significantly lower at 60 min after reperfusion of the graft and at the end of operation in group U than in group C(P
