Objective To investigate the levels of cytokines in sera of patients with various types of psoriasis.Methods Six cytokines, sIL-2R、 IL-2、 -4、 -10、 -12 and IFN-γ , were detected by sandwich ELISA in the sera from 15 patients with guttate psoriasis, 23 plaque psoriasis, 9 pustular psoriasis, 9 arthropathic psoriasis and 9 erythrodermic psoriasis.Results Significantly higher levels of cytokines were observed in guttate psoriasis for sIL-2R (P<0.01), in plaque psoriasis for IL-4,-12 and sIL-2R (P< 0.05 or < 0.01), in pustular psoriasis for IL-4 and -10 (P< 0.05), in arthropathic psoriasis for IL-10 (P< 0.01), in comparison with the controls.The levels of the six cytokines were increased in erythrodermic psoriasis with no significant difference from the controls.The ratio of the average level of IL-4 to IFN-γ was 1.57 in pustular psoriasis, 0.61 in plaque psoriasis, 0.30 in gutatte psoriasis, 0.24 in erythrodermic psoriasis, and 0.02 in arthropathic psoriasis.Conclusion There is different expression of cytokines in sera of patients with various types of psoriasis.

OBJECTIVETo understand the infantile nocturnal sleep-wake pattern developmental trajectory with Actiwatch, which would benefit the clinical assessment of infantile sleep.
METHODThis study was a longitudinal study conducted between 7 Oct, 2009-30 Oct, 2011 in 10 hospitals of 9 cities of China ( Beijing, Xi'an, Qingdao, Wuhan, Changsha, Chongqing, Huzhou, Xiamen and Liuzhou). Actiwatch was used to track the sleep-wake pattern development trajectory of healthy infants in the first year of life in the home setting. Participating infants were followed up at 10th day and 28th day during the first month, and then monthly from the second to the sixth month after birth, and then at ninth and twelve months of age respectively. Meanwhile, infantile sleep was observed continuously for about 60 hours at each visit. According to the characteristics of repeated measurement data of this study, two-level random effect model was adopted to analyze the trend of infantile nocturnal sleep-wake parameters changing with age, and the gender difference.
RESULTA total of 473 healthy infants were included in this study, among whom 246 (52.0%) were boys, and 227 (48.0%) were girls; 355 (75.1%) infants completed the whole year follow-up survey. With infants' age increasing, the latency of infants' nighttime sleep onset decreased from 66.8 minutes on 10th day to 15.5-18.7 minutes at 6-12 months of age. The number of night wakes also decreased with age, while uninterrupted sleep periods lengthened with age. On the 10th day, there were 3.0 times of nightwaking on average, and the longest continuous sleeping interval lasted for 227.6 minutes on average. At 12-month of age, infants could sleep continuously for 350.9 minutes at most on average, while the number of nightwaking decreased to 1.6 times per night on average. Generally, nighttime sleep efficiency increased from 66.3% on the 10th day to 86.3% at 12-month of age. The differences of sleep-wake patterns between boys and girls presented as boys' nocturnal longest uninterrupted sleep period was 19 minutes shorter(266.6 vs. 285.6 min), and the average nighttime sleep efficiency was 2.2% lower (74.2% vs. 76.4%) compared with girls respectively. And the differences of sleep efficiency between boys and girls reduced gradually along with the growth.
CONCLUSIONDuring the first 6 months after birth, infantile sleep-wake pattern undergo obvious change. The capability of sleep-onset and uninterrupted sleep improved with age, and the sleep efficiency increased.

OBJECTIVE To provide a reference for medical staff to timely identify and treat perinatal anaphylactic shock. METHODS The clinical pharmacists participated in the rescue process of anaphylactic shock caused by esketamine during cesarean section anesthesia in a full-term pregnant patient at the Department of Obstetrics and Gynecology of Sichuan Provincial Maternity and Child Health Care Hospital. By consulting the relevant drug instructions and searching the relevant literature, clinical pharmacists assisted physicians in identifying anaphylactic shock and amniotic fluid embolism, analyzing the correlation between the drugs used and adverse reactions, and providing medication education. RESULTS The patient developed hypoxemia and hypotension after anesthesia, and there was no coagulation dysfunction. After symptomatic treatment with adrenaline, the condition rapidly improved, so it was diagnosed as anaphylactic shock. Based on the patient’s medication use and the characteristics of adverse reactions, combined with the National Adverse Drug Reaction Monitoring Center’s criteria for determining the association between drugs and adverse reactions and Naranjo’s evaluation scale, it was comprehensively determined that the suspected allergenic drug causing anaphylactic shock was esketamine. The clinical pharmacist informed the patient that she must inform the physician of the relevant medications for this severe allergic reaction during her later visits. The patient recovered and was discharged on the 6th day after cesarean section. CONCLUSIONS The clinical manifestations of anaphylactic shock and amniotic fluid embolism are similar, and careful differentiation is needed in clinical practice; if a patient experiences a systemic allergic reaction caused by drugs, the suspected drugs should be stopped promptly and effective symptomatic treatment should be taken immediately to delay or terminate disease progression and ensure the patient’s life safety.
