Objective To construct several human proinsulin mutants plasmid related to diabetes and to express in INS-1 (Insulin secreting beta cell derived line) cell. Methods Human mild proinsulin gene was used as template , and site-directed mutagenesis PCR was employed to generate four human proinsulin plasmid mutants. Each mutant plasmid was sequenced then transfected with empty plasmid and mild plasmid into INS-1 cell by liposome 2000. Insulin value in each cell solution was determined by radioimmunoassay. Results Proinsulin mutants plasmid were confirmed by sequencing. In-sulin values in culture solution of H-C(B19)G、H-L(B11)P、H-R(S6)C mutants are less than those in wild type and H-F (B25)L(P＜0.05). Comparison of insulin values between H-C(B19)G、H-L(B11)P、H-R(S6)C groups were not statistically significant(P>0.05), and all these three groups showed no significant differences with empty plasmid group statistically (P>0.05).Insulin value of H-F(B25)L was of no significant differences statistically with empty plasmid(P>0.05). Conclu-sion Four human proinsulin mutants plasmid were constructed and expressed successfully in INS-1 cell, and different mu-tants plasmid result in diabetes through different mechanism.

Objective To explore the correlative factors of phlebitis caused by iron sucrose injection through intravenous drip in Department of Orthopedics so as to provide a basis for take pertinently preventive steps. Methods A total of 588 inpatients with iron sucrose injection through intravenous drip in Department of Orthopedics of West China Hospital, Sichuan University were selected, by convenient sampling from December 2016 to May 2017. This research recorded the ages, sexes, whether they were with hypertension, body mess index (BMI), vascular condition, retaining time and models of detaining needle, concentrations of iron saccharate, daily infusion quantity, days using iron saccharate, seniority of puncture nurses, whether there were with phlebitis through the correlative factors of phlebitis caused by iron sucrose injection through intravenous drip record sheet. Single factor and multiple factors Logistic stepwise regression was used to analyze the influencing factors of phlebitis. Results There were 69 cases (11.73%) with phlebitis in patients with ron sucrose injection treatment. Single factor analysis showed that there were statistically significant differences in the incidence of phlebitis among different sexes, daily infusion quantity, vascular condition, retaining time of detaining needle, type of detaining needle concentrations of iron saccharate of patients (χ2=8.654,32.587,68.313,136.206, 10.662,10.191; P<0.05). Logistic regression analysis revealed that the independent risk factors of phlebitis caused by iron sucrose injection through intravenous drip included daily infusion quantity, retaining time of detaining needle, concentrations of iron saccharate, and the protective factors of that involved the vascular condition and the type of detaining needle. Conclusions Take pertinently preventive steps actively when patients in Department of Orthopedics are with iron sucrose injection through intravenous drip so as to lessen the suffering of the patients.

ObjectiveTo investigate the expression levels of the type Ⅰ IFN system in muscle and lung of experimental autoimmune myositis (EAM) model and to evaluate whether the type Ⅰ IFN system associates with the pathogenesis of the EAM model in rats.MethodsThe EAM model was established to determine creatine kinase (CK) in blood serum.The pathology of muscle and lung tissue was examined by hematoxylin-eosin staining.The concentration of type Ⅰ IFN system mRNA in muscle and lung tissue was detected by real-time PCR.ResultsThe concentration of CK in model group [(209.17 ±91.95) IU/L]was significantly higher than that of two control groups(P ＜0.05).The scores of muscle and lung in EAM model were significantly higher than that of control groups (all P ＜ 0.05).The expression levels of the type Ⅰ IFN system in muscle of EAM model were significantly higher than that of control groups(all P ＜0.05).The expression levels of the type Ⅰ IFN system in muscle with EAM model were positively correlated with CK and the scores of muscle (all P ＜ 0.05).The expression levels of IFNα, IFNβ, IFNαR1, signal transducer and activator of transcription 1 (STAT1), myxovirus resistance protein 1 (MX1) in lung of EAM model were significantly higher than those of control groups(P ＜ 0.05), but not seen in INF-induced protein with tetratricopetide repeats 1 (IFIT1) and IFN-stimulated gene 15 (ISG15).The expression levels of IFNα, IFNβ, IFNαR1, STAT1 and MX1 in lung with EAM model were positively correlated with the scores of lung pathology (all P ＜ 0.05).ConclusionThe type Ⅰ IFN system probably played a crucial role in the pathogenesis and the pathology of muscle and lung of EAM modeL

Objective To investigate the effect of intensive lipid-lowering therapy on the imbalance between inflammatory and anti-inflammatory responses in patients with acute coronary syndrome (ACS).Methods Observed serum levels of hs-CRP and IL-IO in 82 patients with ACS, 17 patients with stable angina, and 22 controls. Forty-one patients with ACS were randomized to take either atorvastatin 10 mg/d (standard lipid-lowering therapy) or atorvastatin 40 mg/d (intensive lipid-lowering therapy) for one month in addition to their routine anti-anginal treatment. Serum levels of hs-CRP, blood lipids, IL-10 were investigat-ed.IL-10 was measured by ELISA. Results The level of hs-CRP in patients with ACS [(11.10 ± 14.30)mg/L] was higher than that in patients with stable angina [(2.47 ± 2.72) mg/L]and controls [(2.34 ± 4.22)mg/L] (P all < 0.05 ). The level of IL- 10 was lower in ACS patients [( 3.94 ± 1.91 ) ng/L] compared with those who had stable angina [(6.31 ± 4.26) ng/L] and controls [(7.76 ± 2.82) ng/L], Pan <0.05. The level of hs-CRP in patients with ACS was decreased and IL-10 was increased after one month treatment with atorvastatin (P < 0.05).The effect of atorvastatin 40 mg/d was more effective than that of atorvastatin 10 mg/d.Conclusions Patients with ACS have higher level of hs-CRP and lower level of IL-10 than those with sta-ble angina. This finding suggests that imbalance of inflammatory and anti-inflammatory responses is related with aggravation of atherosclerotic disease. Intensive lipid-lowering therapy is more effective than standard lipid-lowering therapy on ameliorating the imbalance.

[Summary] A case of primary hyperparathyroidism ( PHPT ) complicated with Graves′disease was reported.The parathyroid lesion( s) could not be identified by repeated MIBI and ultrasonography tests.With the control of hyperthyroidism, medical therapies of hypercalcemia were still not effective, the serum calcium levels continued to be high.Thus, the decision to operate was made.The pathological findings confirmed the diagnosis of parathyroid adenoma.For PHPT patients with clear surgical indications, even though the pre-operative localizing tests are negative, operation is still worth to try.
