Objective To study the role of the expression levels of 5 type Ⅰ interferon (IFN)-inducible genes (LY6E, OAS1, OASL, MX1, and ISG15) in the diagnosis and disease activity evaluation of systemic lupus erythematosus (SLE). Methods Peripheral blood was obtained from 68 SLE patients, 50 patients with other connective tissue diseases and 26 normal controls, and total RNA was extracted and reverse transcribed into complementary DNA. Real-time PCR technique was used to determine gene expressions at transcription level. An IFN score for each individual was calculated according to the expression of 5 1FN genes. Comparisons of gene expression and IFN score were made among groups. The genes expression levels in patients with SLE were analyzed using receiver operative characteristic curve. The association between IFN scores and disease activity, as assessed by the SLEDAI scores and 24 h proteinuria, was analyzed using Spearman correlation analyses. Results ① The expression levels of MX1, OASL, OAS1, ISG15 and LY6E mRNA in SLE patients were significantly increased as compared with normal controls and disease controls (P all<0.01 ).② IFN scores in SLE patients (17.9±29.1) were significantly increased as compared with normal controls (0±3.3)and disease controls (3.0±8.1) (P all<0.01 ). ③ IFN scores area under the ROC curve (AUCROC) was 0.846. When The IFN scores reached 2.56, its sensitivity and specificity for the diagnosis of SLE were 93.1%and 78.3%, respectively. ④ Levels of IFN score was positively correlated with SLEDAI scores (r=0.256,P<0.05) and 24 h proteinuria (r=0.337, P<0.05). Conclusion The 5 IFN-inducible genes are highly expressed in SLE patients. IFN score level is valuable for the diagnosis of SLE and a high IFN score is usually associated with an elevated disease activity.

The bioactive materials, such as biological glass, hydroxyl apatite, glass ceramics which contains the hydroxyl apatite and wollastonite, are possible to unify with the bone tissue together. However, many questions like whether the materials contact and unify directly with the bone, whether the speeds of unification have the differences, and whether materials themselves simultaneously have abilities to promote the bone formation are not clear and wait for the exposition. The researches have been made to observe the contact surface between biological material and bone, as well as the relationship among the apatite level and the bioactivity of materials through the transmission electron microscopy. In addition, in vivo hybridization has been used to discuss the mRNA expression and its influence in the cell around materials. The conclusion is that the bioactivity of glass ceramics is higher than that of hydroxyl apatite, with the easy unification with bone tissue.

Objective To explore the role of clinical pharmacists in rational drug use through the pharmacy care of an elderly pneumonia patient with Chlamydia psittaci infection and drug-induced liver injury. Methods The clinical pharmacists participated in the treatment of one patient with Chlamydia psittaci pneumonia and drug-induced liver injury. Based on the results of second-generation gene sequencing, the characteristics of the pathogen were learned by literature search. The clinical pharmacists monitored the patient’s liver and kidney function, provided a new medication treatment plan to Doctors, and performed patient education during the treatment. Results The initial empirical anti-infective treatment with teicoplanin and imipenem-cilastatin was not effective. After the diagnosis of Chlamydia psittaci and Candida albicans infection, the combination of doxycycline with azithromycin and fluconazole was administered. Drug-induced liver injury was found with this treatment. The clinical pharmacist proposed to switch to doxycycline and clarithromycin with co-administration of magnesium isoglycyrrhizinate and polyene phosphatidylcholine to protect the liver. With this new regime, patient's liver function was improved and the infection was under control. Conclusion Individualized pharmaceutical cares provided by clinical pharmacists helped the safe, rational and effective use of medications.

Objective The sirolimus-eluting stent (SES) has dramatically reduced the rate ofrestenosis in comparison to that with the bare-metal stent (BMS).This study aimed to evaluate the short-term efficacy and safety of Firebird stent implantation for patients with coronary heart disease (CHD). Methods From Apri12006 through July 2007, 155 patients (mean age 58.93~10.27 years) with CHD were implanted with Firebird stent or Cypher select stent at Daxing Hospital. Patients were followed up for one year. All-cause mortality, major adverse cardiac events (MACE, including cardiac death, myocardial infarction, recurrence of angina pectoris, heart failure, revascularization, and adverse arrhythmia) and stent thrombosis were compared between the 2 groups. Results Of the 155 consecutive patients, 147 patients were revascularized completely. Of these patients, 48 (with 59 lesions) were treated with Firebird stent, 59 patients (with 75 lesions) with Cypher select stent. The demographic characteristics were similar in the 2 groups. All the angiographic and procedural results were not significantly different between the 2 groups. All-cause mortality, myocardial infarction, recurrence of angina pectoris, MACE and stent thrombosis were almost identical between the 2 groups before discharge, at 6 months and at one year .Conclusion The short-term efficacy and safety of Firebird stent are similar to that of the cypher select stent for the treatment of patients with CHD.

OBJECTIVETo investigate the clinical characteristics, renal pathology, treatment and prognosis of children with atypical hemolytic uremic syndrome associated with H factor antibody.
METHODFour children less than 18 yr of age admitted from Nov. 2010 to May 2011 in Peking University First Hospital were included. They all met the criteria for atypical hemolytic uremic syndrome and with positive serum anti factor H antibody. They aged from 5 to 11 yr. Data on clinical manifestations, renal pathology, treatment and prognosis were analyzed.
RESULTAll of the 4 cases had gastrointestinal symptoms such as vomiting, abdominal pain, or abdominal distension. None of them had diarrhea. Two children had hypertension. One child had episodes of convulsion. One child had history of atypical hemolytic uremic syndrome. All of them had low serum complement C3. Three of them had low serum factor H (38.0, 88.4, 209.4 mg/L). All of them had serum antibody to factor H (1: 7 068, 1: 1 110, 1: 174, and 1: 869). Three of them received renal biopsy, all of them showed thrombotic microangiopathy. All of them were treated with steroid combined with mycophenolate mofetil. Two children received plasma exchange. They were followed up for 8 to 29 months. The renal function became normal and proteinuria relieved in all of them. The serum factor H concentration increased to 405.8, 155.8 and 438.4 mg/L, respectively. The titer of anti factor H antibody decreased to 1: 119, 1: 170, 1: 123, and 1: 674, respectively.
CONCLUSIONGastrointestinal symptom is common in children with atypical hemolytic uremic syndrome associated with H factor antibody. Hypocomplementemia was observed in all of them. Steroid combined with mycophenolate mofetil seemed to be effective for them. The monitoring of serum factor H and antibody to factor H may help diagnosis and treatment.
