Objective To investigate the expression of cellular chemokine CCL22 and its receptor CCR4, as well as its clinical significance in systemic lupus erythematosus (SLE), along with its roles in the pathogenesis of this disease. Methods Forty-eight patients with SLE and 26 normal human controls were recruited into this study. The patient cohort included 2 males and 46 females with an average age of 33.98± 12.73 years and disease course of 1 month to 20 years. Blood samples were collected from the subjects. ELISA and flow cytometry were used to examine the plasma concentration of CCL22 together with the CCR4 expression on peripheral blood cells. SLEDAI was applied to evaluate the severity of SLE patients. Results The plasma concentration of CCL22 was 227.03±122.84 ng/L in SLE group, 369.53±79.10 ng/L in the control group, 168.09±61.83 ng/L in patients with lupus nephritis and 292.77±163.45 ng/L in patients without lupus nephritis; there was a significant difference between the SLE patients and normal con-trols (P < 0.05) as well as between patients with lupus nephritis and those without (P < 0.05). Increased percentage of CCR4-expressing cells were observed in the peripheral blood of patients with SLE compared with the controls (20.24%±13.86% vs 10.44%±3.07%, P < 0.01), and the percentage of CD3+CCR4+ cells was significantly higher than that of CD3-CCR4+ cells. Moreover, a decrease was noted in the plasma con-centration of CCL22 in severe patients (P < 0.05). In SLE patients, the percentage of CCR4 increased with the rise in SLEDAI score, whereas the plasma concentration of CCL22 negatively correlated with SLEDAI score (r = -0.308, P < 0.05). Conclusion CCL22/CCR4 may play a certain role in the development, pro-gression and organ involvement in SLE.

Objective To observe the clinical effect and safety of polymorphous light eruption(PLE) and those of chronic actinic dermatitis(CAD) treated with Artemtherin.To further study better treatment methods for photodermatitis.Methods 105 patients with CAD and 63 patients with PLE were divided into the treatment group and the control group randomly.In the treatment group,63 cases of CAD and 32 cases of PLE were treated with Artemtherin.In the control group,42 cases of CAD and 31 cases of PLE treated with Hydroxychlorquine.The dosages of both groups were 40 mg and 200 mg at each time,twice a day respectively.Both groups were topically treated with 10% ointment zinc oxide,twice a day,for one month.Results The effective rate of treatment group and control group with PLE patients were 84.4%(27/32) and 80.6%(25/31),respectively.There was no significant difference between both groups in terms of the effective rate of PLE.The effective rate of treatment group and control group with CAD patients were 85.7%(54/63) and 81%(34/4),respectively.There was not any side-effect reported among these patients treated with Artemtherin.Conclusions It is effective,safe,economic,and convenient to treat PLE and CAD with Artemtherin.

Objective To analyze the clinical and laboratory characteristics of systemic lupus erythematosus (SLE) in children. Methods Fifty-three inpatients, 5 boys and 48 girls with SLE, who aged from 7 to 14 years with a median age at 12 years, were enrolled into this study. A retrospective study was carried out to assess the clinical and laboratory features of these pediatric patients. Results The ratio of male to female patients was 1:9.6. Skin eruption was the most common initial manifestation (41.51%), followed by fever (20.75%) and arthralgia (20.75%). Systemic involvement was common, and 84.90% of these patients had hematological abnormalities, 60.38% renal involvement, 18.87% nervous involvement. The most common manifestation of hematological, renal and nervous involvement was anemia, proteinuria and seizures, respectively. Among the immunologic parameters tested, anti-nuclear antibody showed the highest positivity rate of 90.57%, followed by anti-dsDNA with a positivity rate of 67.92%. There was no significant difference between the male and female patients in the age of onset, SLEDAI score at admission and discharge, duration of hospitalization or the dose of corticosteroid used initially and at the discharge. Conclusion The manifestations of pediatric SLE are various, and multisystem involvement is common in these patients. Early diagnosis and active treatment might benefit the prognosis of pediatric SLE.

First, simply expounded the purpose and meaning of detecting tungsten extracted from prefi lable syringes: And then, designed simulation experiment for extracting tungsten from prefi lable glass syringes. and established determination methods of tungsten content by ICP-MSL Finaly, evaluated the limit of content of tungsten ?extracting from simulation experiment.

Objective To explore the effect of cognitive thinking rehabilitation nursing on the delayed encephalopathy after acute CO intoxication .Methods From October 2012 to May 2013 , totals of 37 cases with delayed encephalopathy after acute CO intoxication were selected as study group , and others 33 cases during November 2013 and May 2014 were recruited as control group .Study group received the rehabilitation nursing of cognitive thinking on the basis of routine nursing , while control group received the routine nursing only .Then, the clinical effect of two groups were observed .Results After the intervention , the scores of MMSE , HDS and ADL in study group were (16.87 ±3.95),(18.90 ±3.65) and (42.12 ±10.21),that respectively higher than before the intervention (25.04 ±2.00),(26.04 ±1.71) and (86.12 ±8.93),and the differences were statistically significant (P<0.05).In control group, scores of MMSE [(21.05 ±1.75) vs (16.86 ±3.92)], HDS[(20.97 ±1.65) vs (18.06 ±3.70)] and ADL[(65.52 ±10.38) vs (43.01 ±11.23)] after the intervention were higher than that before , and the differences were statistically significant (P<0.05).After the intervention , the scores of MMSE , HDS and ADL in study group were significantly higher than that in control group (t=3.449,6.747,4.758,respectively;P<0.05),and the nursing satisfaction of patients in study group was significantly higher than that in control group (97.30% vs 87.88%;χ2 =2.333, P <0.05). Conclusions Strengthen the rehabilitation nursing intervention of cognitive thinking can improve cognitive and self-care abilities of patients with delayed encephalopathy after acute CO intoxication , and improve patients ’ satisfaction,which is worthy of clinical popularization and application .

OBJECTIVE To explore the role of clinical pharmacists in the treatment of critical patients with acute heart failure after percutaneous coronary intervention （PCI）， and to provide reference for drug treatment and monitoring of such patients. METHODS Clinical pharmacists participated in the treatment of a critical patient with acute heart failure after PCI， and assisted physicians to jointly develop individualized medication plans based on domestic and foreign literature： it was suggested to give imipenem and cilastatin for anti-infective therapy， adjust drug dose according to renal function， and timely descend step therapy； Levetiracetam tablets were selected to prevent epilepsy； the differential diagnosis and treatment of rhabdomyolysis possibly caused by Atorvastatin calcium tablets were performed； the whole process of pharmaceutical care was conducted. RESULTS Physicians adopted the suggestions of clinical pharmacists. The acute heart failure of the patient was controlled， the pulmonary infection was improved， the adverse reaction symptoms were relieved， and the patient was successfully transferred out of the ICU. CONCLUSIONS For severe patients， when giving imipenem and cilastatin for anti-infection treatment，the clinical pharmacist should adjust the dose according to the patient’s renal function and be alert to the possible neurotoxicity. During the treatment with Atorvastatin calcium tablets，the clinical pharmacist should comprehensively analyze the risk of rhabdomyolysis. For the adverse reactions that have occurred， clinical pharmacist should promptly address symptomatic issues to ensure the safety and effectiveness of medication for patients.
