Objective:To analyze clinical characteristics of drug-induced hypersensitivity syndrome (DIHS) , and to compare the European, Japanese and Chinese diagnostic criteria.Methods:A total of 45 patients confirmedly diagnosed with DIHS according to the DIHS criteria originally proposed by Bocquet, were collected from the First Affiliated Hospital (Southwest Hospital) of Army Medical University between January 2009 and January 2019. Clinical data on the 45 patients were retrospectively analyzed, clinical characteristics were summarized and re-evaluated according to the European, Japanese and Chinese diagnostic criteria separately, and differences were analyzed in terms of the latency period, time to rash regression, eosinophil count, liver function indices, etc. One-way analysis of variance was used to compare means among multiple groups, and t test to compare means between two groups. Results:Of the 45 patients, 38 presented with eruptive drug eruptions, and 44 were accompanied by liver damage, 40 by elevated counts of peripheral white blood cells, 38 by eosinophilia, 21 by lymphadenectasis, and 4 by mucosal damage. Common culprit drugs included allopurinol (10 cases) , anti-tuberculosis drugs (7 cases) , cephalosporins (7 cases) , and Chinese medicine (4 cases) . Forty patients were treated with glucocorticoids, and 17 with glucocorticoids and intravenous gamma globulin. After treatment, 44 patients received improvement and 1 died. According to the European diagnostic criteria, there were 29 patients with suspected DIHS and 16 with confirmed DIHS; according to the Japanese diagnostic criteria, 37 patients could be confirmedly diagnosed with DIHS, but 8 could not be confirmedly diagnosed; according to the Chinese diagnostic criteria, 17 patients could be confirmedly diagnosed, but 28 could not be confirmedly diagnosed. According to the Japanese diagnostic criteria, the latency period was significantly longer in the patients with a confirmed diagnosis (36.91 ± 21.73 d) than in those without (20.00 ± 20.82 d, P = 0.04) . Conclusions:Common culprit drugs for DIHS include allopurinol, anti-tuberculosis drugs and cephalosporins. Most patients with DIHS are accompanied by liver damage, and the European diagnostic criteria are preferentially recommended for DIHS.

Objective To investigate the feasibility of double low scanning technique using the gem spectrum CT coronary artery angiography among the patients at low heart rate≤ 65 beats per minute.Methods This prospective study was approved by the institutional re-view board with patient informed consent.Ninty patients (heart rate≤65 beats per minute)were randomly devided into 3 groups.Group A un-derwent spectral CCTA with iodixanol (Visipaque,270mg/mL)and low scanning technique,Group B conventional CCTA with iohexol (Omnipaque,370 mg/mL)and Group C conventional CCTA with iodixanol (Visipaque,270 mg/mL),Routine scan mode was used in Group B and Group C.Prospective ECG gating mode was used in all groups.120kVp polychromatic images with FBP algorithm (Group B and Group C)were reconstructed for conventional CCTA,60 keV monochromatic images with FBP algorithm (Group A) or with a fixed blending level (40%)of ASiR (Group A1 )were reconstructed for spectral CCTA.Compared the image quality of four groups and ED in three groups.Results The difference was ststistically significant between four groups with the CT value,im-age noise,SNR and CNR of coronary (each P<0.001.Group A1 has the highest SNR and CNR.Group C has the lowest image noise.There were no significant difference of coronary score between group A1 and group B(χ2=0.01,P=1.000)).There was significant difference of coronary score between group A and group B (χ2=22.428,P<0.001),group B and group C (χ2=39.005,P<0.001), group A1 and group A (χ2=21.854,P<0.001).Effective radiation dose in the group A(ED2.60±0.26 mSv)was lower than that of group B (ED3.02±0.36 mSv)(t=3.738,P=0.001)and group C (ED3.11±0.23)(t=3.725,P=0.001).Conclusion Double low scan-ning technique using the gem spectrum CT coronary artery angiography with 40% blending level of ASiR is able to provide better im-age quality than using conventional CCTA and to reduce the effective radiation dose and contrast dose.

Objective To investigate the relationships between the expressions of cidA and lrgA and the biofilm formation of Staphylococcus epidermidis clinical isolates. Methods Thirty-nine S. epidermidis clinical isolates were divided into biofilm formation group and non-biofilm formation group according to adhesion assays and icaA amplification, 20 strains for biofilm formation group and 19 strains for another group respectively. Amplify cidA and lrgA fragment with PCR, detect mRNA levels of cidA and lrgA with RT-PCR and then calculate the ratios of cid/lrg mRNA. Results All of the 39 isolates of S. epidermidis existed cidA and lrgA gene.Select 2 strains of S. epidermidis, Y36 and Y26, at random for detecting the cidA and lrgA mRNA levels of different phases, the highest level of cidA mRNA shows on 4 h's culture while lrgA shows on6 h. The relative expression levels of cidA of 39 isolates of S. epidermidis were 0.340 + 0.250 in biofilm formation group and 0. 406 +0. 408( P =0. 541 ) in non-biofilm formation group for 4 h culture, while the relative expression levels of lrgA were 0.325 ± 0.218 and 0.253 ± 0.211 respectively ( P = 0. 299). There were no significant differences between these two groups. The ratios of cid/lrg mRNA were 1.067 ±0.529 and 1.958 ±1.877 respectively, the difference of population distribution was significant( P = 0.001 ). Conclusion The expressions of cidA and lrgA of S. epidermidis clinical isolates may be time-limited. There were no significant differeces of expressions of cidA and lrgA between biofilm formation group and non-biofilm formation group. The ratios of cid/lrg mRNA maybe have some biological significance.

The radioactive iodine uptake(RAIU) has great value in determining the 131I treatment dosage of patients suffered from hyperthyroidism and judging thyroid function. Many factors which could interfere the results of RAIU were as follows: instrumental factors, thyroid radioactivity counts measurement, counts of a calibrated standard in a neck phantom and counts of room background, iodinated drugs and food, anti-thyroid medication, among other causes, have shown to induce varying degrees of errors in RAIU measurements. Irregular measurements which may interfere with radioactive iodine uptake are commonly seen in clinical practice, yet its actual influence has not been reported. Optimization, regularization and quality control of the radioiodine uptake measurement are essentials for clinical routine practice to guarantee appropriate values for clinical hyperthyroidism diagnosis and treatment. All the above factors affecting the measurement of thyroid function instrument for radioactive iodine uptake are analyzed and then put forward the corresponding solutions.
