Ubiquitin plays a vital role in both protein degradation and many kinds of cellular functions, such as DNA damage repair, cell cycle regulation, cell growth and immune system function.Ubiquitin modiifed enzyme zinc ifnger protein A20 is considered to be an important gateway for the regulation of immune and inlfammatory responses, which is a key negative regulator in NF-κB signaling pathway. Dendritic cell (DC) is a full-time antigen presenting cell that identifies inflammatory response or pathogenic microorganism by multiple receptors, and is a key moderator for immunity homeostasis. Researches in recent years showed that A20 plays an important role in regulating the function of DC, which may take part in the occurrence and development of inlfammatory bowel disease. In this article, the regulation of A20 in the immunoregulation of DC and its function on the pathogenesis of inlfammatory bowel disease were reviewed.

Background and purpose:To study the expression of PTEN and P53 and analyse their roles in HGC oncogenesis,and to discover a good marker for diagnosis and prognosis of HGC.Methods:The expression of PTEN mRNA,PTEN protein and P53 protein were detected by in situ hybridization(DNA-RNA) and immunohistochemistry(SP method) in 64 cases of HGC.We took 22 cases of gallbladder adenoma and 10 cases of chronic cholecystitis as controls.Results:① The positive expression rates of PTEN mRNA and protein in HGC(56.3%,59.4%) were significantly lower than that in gallbladder adenoma(81.8%,90.8%) and chronic cholecystitis(100%,100%)(P

OBJECTIVETo compare the clinical effective differences between shallow needling and medication for the sleep disorder of schizophrenia.

METHODSNinety-six patients with the sleep disorder of schizophrenia were randomly divided into a shallow needling group and a medication group, 48 cases in each one (one case dropping in the shallow needling group and two cases dropping in the medication group). The same dose paliperidone tablets were adopted in the two groups. In the shallow needling group, the main acupoints were Baihui (GV 20), Shangenxue (Extra) and Ezhongxian (MS 1), and the acupoints based on syndrome differentiation were selected. The shallow needling manipulation was used once a day, 5 times a week. In the medication group, 3 mg eszopiclone tablets were prescribed orally before sleep once every night. The patients were treated for 6 weeks in the two groups. Sleep condition was evaluated by Pittsburgh sleep quality index (PSQI) before and after treatment, and the clinical efficacy and the adverse reaction were assessed by positive and negative symptoms scale (PANSS) and treatment emergent symptom scale (TESS) before and after 2-week, 4-week and 6-week treatment. The clinical effects between the two groups were compared.

RESULTSAfter treatment in the two groups, both the total scores and the each factor score of the PSQI and the PANSS were apparently decreased (P<0. 05, P<0. 01). As for the PSQI scale, after treatment the daytime dysfunctional score of the shallow needling group was reduced more obviously than that of the medication group (P<0. 05), and the falling asleep time in the medication group was declined more markedly compared with that in the shallow needling group (P<0. 05). Regarding the PANSS, the improvement of the pathological factor in the shallow needling group was better than that in the medication group after treatment (P<0. 05), and the improvement of the positive factor in the medication group was superior to that in the shallow needling group after treatment (P<0. 05). The total scores and each factor score of the PSQI and the PANSS were not statistically different between the two groups after treatment (P>0. 05). At the end of the 6th week, the curative and effective rate was 63. 9% (30/47) and the total effective rate was 95. 8% (45/47) in the shallow needling group;the curative and effective rate was 58. 7% (27/46) and the total effective rate was 91. 3% (42/46) in the medication group. The difference of the effect was not statistically significant between the two groups (P>0. 05). The scores of TESS in the shallow needling group were lower than those in the medication group (P<0. 01, P<0. 05).

CONCLUSIONThe effect of shallow needling for assisting the sleeping disorder of schizophrenia is reliable and it is similar with the efficacy of eszopiclone. Also, the shallow needling can improve the daytime dysfunction and the pathological factor apparently without adverse reaction and pain. Its safety is obviously better than that of eszopiclone.
