Patient one was a 19-year-old woman of periodic fever with urticaria during the first week of life.And there were typicalfacies,oligoarthritis and central nervous system involvement.She also exhibited a persistent elevation of acute phase reactants.The diagnosis of chronic infantile neurological cutaneous and articular syndrome was made.Short-term dosing of tumor necrosis factor-α receptor antagonist was administrated and was substituted by glucocorticoid and methotrexate.Another two males had an earlyonset of increased acute phase reactants during inflammation attacks.One of them had recurrent fever with urticaria-like rash,arthralgia and headache.Muckle-Wells syndrome was diagnosed on basis of NLRP3 gene mutation (c.92A ＞ T).And another had recurrent urticaria-like rash with conjunctivitis,oligoarthritis,hepatosplenomegaly and increased serum IgD.The clinical diagnosis was mevalonate-kinase deficiency.Autoinflammatory diseases should be suspected by physicians and diagnosed with a combination of phenotype and genotype.Biological agents,especially interleukin-1 antagonist,have broad prospects in the therapy of autoinflammatory diseases.

Objective To update the knowledge on the sensitizing drugs and clinical features of drug eruption. Methods The clinical data on 138 patients hospitalized for drug eruption in the Department of Dermatology, Institute of Dermatology, Chinese Academy of Medical Sciences, from January 2005 to June 2007, were collected and retrospectively analyzed. Results Totally, 178 episodes of drug eruption were observed in these patients during the tested period. The major sensitizing drugs included antibacterial agents (31.46%), non-steroidal anti-inflammatory drugs (28.09%), traditional Chinese medicines (15.73%). Amoxicillin triggered 20 episodes of drug eruption and was the most common causative drug. Oral administration was the predominant sensitizing route of administration (54.17%). Of all the drug eruptions, 33.71% manifested by erythema multiforme, 28.09% by fixed drug eruption, 22.47% by exanthematous drug eruption. Severe types of drug eruption were mainly caused by traditional Chinese medicines and anti-gout drugs. Conclusions Antibacterial agents and non-steroidal anti-inflammatory drugs have become the major sensitizing drugs of drug eruption, especially amoxicillin. The frequency of traditional Chinese medicine-induced eruptions are increasing. Furthermore, caution is warranted for the drug eruption caused by oral administration.

Double cannulation model of conscious rat allowing simultaneous collection of mesenteric lymph and jugular venous blood was established to investigate the intestinal lymphatic transport of breviscapine orally administered in rat. The concentrations of breviscapine in plasma and lymph were determined by HPLC. The pharmacokinetics of breviscapine after oral and intravenous administration was evaluated in the conscious rat model. It was observed that scutellarin distributed from blood circulation to lymphatic system after intravenous injection. The cumulative lymphatic transport amount within 12 h was (2.78 +/- 0.25) microg, equivalent to 0.0792% of intravenous dose. After oral administration of scutellarin to double-cannulation rats, the cumulative lymphatic transport amount within 12 h was (0.92 +/- 0.08) microg, equal to 0.0083% of oral dose. The absolute bioavailability of breviscapine orally administered to double-cannulation rats was 4.91%, indicating that scutellarin was mainly absorbed into the bloodstream through the portal vein. Lymphatic transport of scutellarin appears to reflect high affinity for the lymph lipoproteins to chylomicron. This study provided a biopharmaceutics basis for developing oral lipid delivery system for the promotion of intestinal lymphatic transport to improve oral bioavailability of breviscapine.

Objective To explore the relationship between the typing of MSCT and prognosis in infant with interstitial pneumonia (IP).Methods MSCT features of 44 infants with IP were analyzed retrospectively and classified according to the pathological pro-gress.The relationship between the MSCT typing and clinical prognosis was statistically analyzed.Results The result of the MSCT typing was as follows:the exudation in 22 cases,the proliferation in 18 cases and the ruin in 4 cases.There was significant difference for the clinical prognosis among the different MSCT groups (P＜0.01 ).And there was a significant correlation between the MSCT typing and clinical prognosis (r＝0.784,P＜0.01).The prognosis of the exudation type was better than the proliferation type,and both of them were better than the ruin type.Conclusion Based on the MSCT features,MSCT typing reveals the inflammatory patho-logical process of the infant IP,which plays an important role in treatment options decision and prognosis prediction.

Objective To discuss the prenatal MRI features and the fetal outcomes of meconium peritonitis (MP).Methods The clinical data of 23 cases with MP were collected.The prenatal MRI features and fetal outcomes were analyzed retrospectively.Results Prenatal MRI features included meconium peritonitis pseudo-cyst (9/23,39.1%),fetal ascites (23/23,100.0%),bowel dilatation (9/23,39.1%), meconium leakage (3/23,13.0%),scrotal effusion (2/23,8.7%)and polyhydramnios (2/23,8.7%).Of the 23 fetuses,2 were induced and 2 1 were delivered.In 2 1 neonates,7 cases received surgical treatment,1 3 cases received conservative treatment and 1 case was dead due to treatment refusal of the family.Neonates with bowel dilatation and meconium leakage all underwent surgery,neonates with meconium peritonitis pseudo-cyst and fetal ascites underwent conservative treatment,and the rate of operation was 100%,100%,22.2% and 35.0%,respectively. Conclusion Prenatal MRI findings of MP are characteristic.Bowel dilatation,meconium leakage,growing meconium peritonitis pseudo-cyst and meconium peritonitis pseudo-cyst connectted with adjacent intestine are highly suggestive of early surgical intervention in neonate.

OBJECTIVETo investigate the association of the polymorphisms of rs4961 in alpha-adducin (ADD1) and rs28933400 in Na+/K+ -ATPase a2 (ATP1A2) genes, the products of which are important for sodium transport, with essential hypertension.

METHODSMutagenically separated PCR (MS-PCR) was used to detect the genotypes of the two loci. The subjects were recruited randomly including 196 patients of essential hypertension and 192 healthy controls.

RESULTSThe frequencies of genotypes and alleles of in the ADD1 gene were significantly different between the patients and controls respectively (P=0.03, P=0.04). There was significant relationship between the genotypes of rs4961 and systolic blood pressure and blood sodium concentration. However, there was no significant relationship between the rs4961 genotypes and diastolic blood pressure, body mass index, blood kalium and chlorine concentrations. There was no polymorphism at the rs28933400 locus in the subjects analyzed.

CONCLUSIONThe rs4961 polymorphism of the ADD1 gene is associated with essential hypertension, but the rs28933400 locus in the ATP1A2 gene may have no association with essential hypertension in the studied population.

OBJECTIVETo investigate the effectiveness of preoperative plateletpheresis combined with intraoperative autotransfusion on the blood coagulation of orthopaedic patients.

METHODSSixty patients (ASA I-II) undergoing selective orthopaedic surgery were randomized into three groups (n = 20), that is, preoperative plateletpheresis combined with intraoperative autotransfusion for group I, intraoperative autotransfusion for group II, and group III without any managements of blood conservation. Coagulation parameters (prothrombin time, partial thromboplastin time, fibrinogen), hemoglobin and hematocrit values, platelet counts and aggregability were evaluated before the anaesthesia, 10 minutes after plateletpheresis, 10 minutes before the infusion of platelet rich plasma or autologous blood, 10 minutes after infusion, 24 and 48 hours postoperation. Intra- and postoperation blood loss and homologous blood transfusion requirements were also recorded.

RESULTSAmong three groups, there were no differences in intraoperative blood loss, perioperative haemoglobin level (Hb and Hct). As compared with group I, significant lower level of platelet counts and aggregability were observed in group II and III at the time of 24 and 48 hours after operation (P < 0.05), while postoperation blood loss and homologous blood-transfusion requirements increased at the same period (P < 0.01).

CONCLUSIONSPreoperative plateletpheresis combined with intraoperative autotransfusion can ameliorate the blood coagulation in orthopaedic patients, and it is an effective way to decrease blood loss and homologous blood-transfusions requirements.
