Atopic dermatitis is a complex chronic, relapsing inflammatory skin disease.Atopic dermatitis in children is usually less severe than in adults, but it is with a high incidence and is susceptible to relapse.Therefore, the physical and mental health of children and their family maybe seriously affected.In the past, the treatments of atopic dermatitis have been limited to glucocorticoids and immunosuppressants.It is unsafe for children because of their toxicities.With the in-depth understanding of pathogenesis, more and more new therapies that focus on intervening in the inflammatory pathway by targeting specific cytokines or their receptors have been found and applied.This article reviews the progress of treatment of the disease to provide new insights for the optimal treatment of atopic dermatitis.

0.05). However, incidences of VRS paining grade, nausea and vomiting in Z-type stainless steel stent group were significantly higher than Ni-Ti alloy mesh stent group (P 0.05). All patients in both groups did not have general toxicity and hypersensitivity reaction, and they had normal cell component, number and form of hematopoieticsystem. CONCLUSION: Both Z-type stainless steel stent and Ni-Ti alloy mesh stent are suitable for alleviative treatment of advanced esophageal cancer; however, side effects induced by Ni-Ti alloy mesh stent is less than by Z-type stainless steel stent in an early postoperative stage.

Objective:To observe the conditions of isolation,purification and culture of mesenchymal stem cells(MSCs) in vitro derived from human umbilical cord,and to observe the repairing effect on experimental hepatic fibrosis in rats by transplantation with MSCs only or MSCs with IL-10.Methods:The MSCs derived from human umbilical cord were isolated,purified and cultivated in vitro.The model of hepatic fibrosis induced by CCl4 was established.After the model of hepatic fibrosis was succeeded,the rats were divided into three groups:model group,MSCs transplantation group,MSCs transplantation with IL-10 group.MSCs transplantation group was given 1×106 MSCs by the tail vein injection at the first 1 weeks,2 weeks and 3 weeks.MSCs transplantation with IL-10 group not only was given MSCs the same with MSCs transplantation group, but also was injected of IL-10 ( 4 μg/kg ) in abdomen, 4 times a week.After 4 weeks,the rats were executed,rats blood was collected to observe the changes of liver function and the index of liver fibro-sis.The liver HE staining was carried out to observe the changes of liver pathology.Expression of MMP-2 mRNA was detected by RT-PCR method,expression of TGF-βprotein was detected by Western blot method.Results:The rat liver function and the index of liver fibrosis improved obviously with a significant difference between model group , MSCs transplantation group and MSCs transplantation with IL-10 group after transplanting,MSCs with IL-10 was better than MSCs only.Liver tissue of rats with hematoxylin eosin staining suggested,liver fibrosis was obviously improved,and the MSCs transplantation with IL-10 group was best.MMP-2 mRNA expression was significantly higher between normal group and model group,MSCs transplantation group with a significant difference (P<0.05),MMP-2 mRNA expression was higher with a no significant difference between model group and MSCs transplantation with IL-10 group ( P>0.05).TGF-βprotein expression of other groups was higher than normal group with a significant (P<0.05),and MSCs transplantation with IL-10 group was the largest decrease than normal group.Conclusion:MSCs only or MSCs with IL-10 transplantation can improve the biochemical characteristics of rat peripheral blood and liver histological structure,and with IL-10 wan better than MSCs only.MSCs and IL-10 play a role in the treatment of liver fibrosis through lowering the expression of MMP-2 and the expression of TGF-βprotein.

Objective To investigate the effects of a highly selective dopamine D4 receptor (ABT-724)on behaviors in Spontaneously hypertensive rats (SHR),a rat model of attention-deficit hyperactivity disorder (ADHD).Methods After intervention of methylphenidate(5mg/kg) and three different doses of ABT-724(0.04mg/kg,0.16mg/kg,0.64mg/kg),behaviors of SHR were verified by open-field test,Morris water maze and Làt maze.Results Number of square crossing after intervention of methylphenidate and ABT-724 in SHR( 70.67 ± 8.59,76.50 ± 10.75,79.17 ± 10.44,65.67 ± 20.62) was less than the saline control group( 130.33 ± 1 1.40) (P＜0.05).During Morris water maze,SHRs(52.50 ± 4.04,52.17 ± 2.99,61 ± 8.15,53.83 ± 9.87 ) after intervention of both had a better spatial memory ability than control group(38.83 ±7.17) (P＜0.05).In Làt maze,number of rearing after intervention of both in SHRs(57.17 ± 5.67,60.83 ± 8.28,55.17 ± 9.45,65.33 ± 9.50 ) was less than saline control group(78.00 ± 13.84) (P＜0.05).Conclusion ABT-724 could improve behaviors of spontaneous locomotor activity,cognitive ability,non-selective attention in SHR.

Objective To investigate the role of spinal glucocorticoid receptors (GR) in phosphoinositide 3-kinase/protein kinase B (PI3K/Akt) signal pathway in rats with morphine tolerance.Methods Forty healthy male SD rats aged 8-10 weeks weighing 300-350 g in which intrathecal (IT) catheters were successfully implanted without complication were randomly divided into 4 groups (n =10 each):control group(group C) received IT injection of normal saline 10 μl twice a day for 7 consecutive days; morphine tolerance group(group M) received IT injection of morphine 10 μg twice a day for 7 consecutive days; dexamethasone (a GR agonist) group( group DEX)received IT injection of dexamethasone 4 μg 30 min before IT injection of morphine,twice a day for 7 consecutive days;RU38486(a GR blocker)group (group R) received IT injection of RU38486 2 μg 30 min before IT injection of morphine,twice a day for 7 consecutive days.Tail-flick test was measured once a day after first IT administration and 1 d after the end of IT administration,and the percentage of maximum possible antinociceptive effect (MPAE)was caculated.After the last measurem of tail-flick test,the spinal dorsal horns were removed for determination of PI3K,Caspase-3 expression and Akt activity.Results Morphine tolerance developed in groups M,DEX and R,but did not develop in group C.Compared with group C,Akt activity was decreased,PI3K expression was downregulated and Caspase-3 expression was up-regulated in group M (P ＜ 0.05).Compared with group M,MPAE and Akt activity were decreased,PI3K expression was down-regulated and Caspase-3 expression was up-regulated in group DEX,and MPAE and Akt activity were inecreased,PI3K expression was up-regulated and Caspase-3 expression was down-regulated in group R (P ＜ 0.05).Conclusion Spinal cord GR is involved in morphine tolerance by inhibiting PI3K/Akt signal pathway.

Objective To compare the efficiency and safety of dezocine and morphine combined with flurbiprofen for gynecologic postoperative analgesia.Methods Ninty patients for elective hysterectomy,ASA (American Society of Anesthesiologists) Ⅰ - Ⅱ,were randomly divided into three groups,given postoperative intravenous analgesic pump:dezocine 50 mg + flurbiprofen 100 mg( Group D) ;morphine 50 mg + flurbiprofen 100 mg ( Group M) ;dezocine 25 mg + morphine 25 mg + flurbiprofen 100 mg ( Group DM ).Anesthesia were induced by midazolam,etomidate,fentanyl and cisatracurium,maintained with propofol and remifentanil.At 15 -30 min before the end of surgery,flurbiprofen 50 mg was given,if pain was not relieved statsifically,morphine 5mg/per time was given additionally.VAS Pain relief scores,Ramsay sedation Score,usage of morphine and side effects such as nausea,vomiting and itch of skin were recorded at 4,8,24,48 h after surgery.Results At 4,8,24 and 48 h after surgery,VAS score at sedation was ( 2.27 ± 0.64 ),( 2.17 ± 0.65 ),( 1.97 ± 0.67 ),and ( 1.60 ± 0.56) in Group D,and ( 2.50 ± 0.63 ),( 2.40 ± 0.62),( 2.20 ± 0.61 ) and ( 1.87 ± 0.57 ) in Group DM at sedation,which were all significantly low than those of ( 3.10 ± 0.76),( 3.00 ± 0.74 ),( 2.80 ± 0.71 )and (2.40 ±0.72)in Group M.At 4,8,24 and 48 h after surgery,VAS score at active was (3.10 ±0.76),(2.97 ±0.76),(2.70 ±0.84) and (2.17 ±0.70)in Group D,(3.43 ±0.63),(3.30 ±0.65),(3.03 ±0.76)and (2.43 ± 0.68 )in Group DM,which were all significantly lower than those of (4.13 ± 0.94),(3.93 ±1.05),(3.60 ± 1.05 ) and ( 3.03 ± 0.96 ) in Group M ( Ps ＜ 0.05).And the VAS scores of Group DM was significantly higher than those of Group D.Sedation score at 48 h after surgery in group D was better than that in Group M ( x2 =4.812,P ＜ 0.05 ),The side effects at 48 h after surgery was 26.7％ in Group D,46.7％ in Group DM and 80％ in Group M,and there significant difference among these 3 groups (P ＜ 0.05 ).Conclusion Compared to Morphine and or Morphine combined with Dezocine,Dezocine 50 mg + flumazenil 100 mg group is better to release the postoperative pain,and withless adverse effects.

OBJECTIVE To compare the effect of four 5-hydroxytryptamine type 4 (5-HT4) receptor agonists:cisapride,zacopride,macopride and 2-[1-(4-piperonyl) piperazinyl]-benzothiazole (BZTZ),on rat cardiac inward rectifier potassium channel (IK1)and heart rhythm.METHODS The whole-cell configuration of patch-clamp technique was used to record effects of 5-HT4 receptor agonists onIk1 in enzymatic dissociated rat ventricular myocytes or Kir2.1 transfected HEK 293 cells.Western blotting was used to observe the expression of Kir2.1 channel exposed 24 h to agents in ventricular myocytes.Langendorff-perfused hearts were perfused with four agents respectively for 30 min.The electrocardiogram was recorded simultaneously.RESULTS BZTZ,cisapride and mosapride 0.1-10 μmol· L-1 decreasedIk1 in a concentrationdependent manner.At the same concentration (1 μmol· L-1),BZTZ showed the most potent inhibition onIκ1 (P＜0.01),followed by cisapride.Mosapride showed slight inhibition efficiency.However,zacopride enhanced Iκ1 (P＜0.01).In Kir2.1 heterologous expression systems,zacopride activated Kir2.1 current (P＜0.01) while mosapride had no effect.In ex vivo Langendorff-perfused hearts,BZTZ and cisapride 1μmol· L-1 elicited singnificant rhythm disturbances,and the total of premature ventricular beats (PVB) were 159±28 and 61±13.50％ (4/8) (P＜0.05) and 25％ (1/8) of the hearts exhibited ventricular tachycardia (VT),while 37.5％ (3/8) and 12.5％ (1/8) of the hearts exhibited ventricular fibrillation (VF),respectively.Mosapride and zacopride had no side effects on heart rhythm.Zacopride also suppressed BZTZ-or cisapride-induced arrhythmias.BZFZ had the strongest proarryhthmic potency among the 5-HT4 agonists,followed by cisapride,mosapride and zacopride.CONCLUSION Iκ1 might be an independent risk factor for arrhythmogenesis and a new target for screening safe 5-HT4 receptor agonists and gastrointestinal prokinetic agents.

OBJECTIVETo explore the impacts on the cognitive level of the children with mental retardation (MR) treated with JIN's three scalp needling therapy and the training for cognitive and perceptual disturbance so as to seek the more effective therapeutic method for the treatment of MR in children. Methods Sixty-six MR children were randomized into a head-point needle-retaining therapy + training group (group A) and a training after acupuncture group (group B). Seven cases and 12 cases were dropped in the two groups respectively. Twenty-six cases accomplished the treatment in the group A and 21 cases in the group B. In the group A, the points on the head were stimulated and the needles were retained (30 min after the general acupuncture, the needles on the body points were removed; and those on the head points were retained for 1 h, including Sishenzhen, Naosanzhen, Zhisanzhen and Niesanzhen). Simultaneously, the training for the cognitive perceptual disturbance was combined. In the group B, 1 h after needle retaining at the body points and head points, all the needles were removed; the training for the cognitive perceptual disturbance was followed. The treatment was given once a day, and the treatment for 3 months was required. Before and after treatment, the Wechsler intelligence scale for children (WISC) was used for evaluation and observation of verbal intelligence quotient (VIQ) , performance intelligence quotient (PIQ) and full-scale intelligence quotient (TFIQ) and score changes of 11 items such as information, picture vocabu; lary, arithmetic, picture generalization, comprehension, etc.

RESULTSAfter treatment, FIQ, VIQ and PIQ scores were different significantly as compared with those before treatment (all P<0. 01). In the group A, the results of picture vocabulary, animal egg laying, maze, block design and geometric figure were all improved significantly (all P<0. 05). In the group B, the results of information, comprehension, block design and geometric figure were all improved significantly (all P<0. 05). After treatment, concerning the value difference in FIQ and PIQ of the two groups; the changes in the group A were more significant (both P<0. 01). After treatment, the results of picture vocabulary and maze were improved significantly in the group A as compared with the group B (both P<. 01). The IQ categories changed apparently after treatment in the two groups, toward the higher level in tendency generally, but without significant difference (both P>0. 05).

CONCLUSIONThe simultaneous treatment with head point retaining of JIN's three needling therapy and the training for cognitive and perceptual disturbance obviously improves children patients' verbal comprehension, expression ability, hand-eye coordination ability, attention, logical reasoning ability and visual perception. The efficacy is better than that in the treatment of the training after acupuncture.

Objective To explore the relationship between serum uric acid and fasting blood glucose ( FBG) in newly-diagnosed type 2 diabetes in regard to different genders. Methods In 282 patients of newly diagnosed type 2 diabetes(208 males and 74 females), detection of serum FBG, uric acid, creatinine, transaminases, blood lipids, etc were determined. FBG<7. 0 mmol/L was found in 118 cases (89 males and 29 females);7. 0 mmol/L≤FBG≤9. 0 mmol/L in 114 cases ( 88 males and 26 females ); FBG>9. 0 mmol/L in 50 cases ( 31 males and 19 females). Results (1)Serum uric acid showed statistically significant difference in regard to sex[Male:(325. 82±92. 26)μmol/L, Female:(292. 26±76. 19)μmol/L, P<0. 01]. (2) FBG and serum uric acid were negatively related(r=-0. 316, P<0. 01). (3) FBG and serum uric acid were negatively related both in male(r=-0. 320, P<0.01)andinfemale(r=-0.291,P<0.05). (4)Multiplestepwiseregressionanalysisshowedthatthethreegroups of FBG and serum uric acid showed regression relationship in male and female patients(P<0. 01). Conclusion With the increased FBG, serum uric acid was decreased in both males and females. Therefore, serum uric acid might serve as a potential biomarker of glucose metabolism.
