G protein coupled receptors (GPCRs) are transmembrane receptor proteins, which allow signals to transfer across membrane. GPCRs include a large number of receptors, different receptors mediated different signaling pathways of GPCRs- adenylyl cyclase (AC)- cyclic adenosine 3' ,5'-monophosphate (cAMP), including β2 adrenergic receptors (β2- ARs)- AC- cAMP signaling pathways, E-prostanoid2/4 (EP2/4)-AC-cAMP signaling pathways. Regulatory proteins, such as G protein coupled receptor kinases (GRKs) and β-arrestins, play important modulatory roles in GPCRs signaling pathway. GPCRs signaling pathway and regulatory proteins implicate the pathogenesis process of inflammatory and immune response. Rheumatoid arthritis (RA) is an autoimmune disease characterized by synovitis and accompanied with inflammatory and abnormal immune response. This article review the advances on GPCRs signaling pathway implicating in the inflammatory and immune response of RA.

The modern literatures on the diseases treated with acupuncture at Shenmen (HT 7) were collected. Using literature statistical analysis in bibliometrics, the common compatibility of Shenmen (HT 7) and the disease spectrum were analyzed so as to provide the references of the diseases that can be treated with acupuncture at Shenmen (HT 7). It was found that 39 kinds of diseases and symptoms, mainly nerve system disedses, could be treated with acupuncture at Shenmen (HT 7), including insomnia, depression, anxiety and dementia. Shenmen (HT 7) was seldom used alone. Instead, it was commonly used along with Baihui (GV 20), Sanyinjiao (SP 6), Neiguan (PC 6), Sishencong (EX-HN 1) and Taicong (LR 3).

OBJECTIVETo observe the effect of xiaomi granules (XMG) for treatment of HIV/AIDS oral candidiasis.

METHODSForty patients in the treated group were treated by XMG and 40 patients in the control group were treated with anticandine. The therapeutic course for both groups was two weeks. Changes of clinical symptoms, oral candida microscopic examination and cultured before and after treatment as well as the safety of treatment were observed, and a follow-up study was implemented two weeks after ending medication to compare the relapse rate between groups.

RESULTSSymptoms as oral greasy-sticky, thirsty, asthenia, abdominal distension and anorexia were improved after treatment in both groups (P < 0.05). The improvements of oral greasy-sticky and thirsty in the treated group were better than those in the control group (P < 0.05). The effective rate and relapse rate in the treated group was 90.0% (36/40) and 11.1% (4/36) respectively, while in the control group, 72. 5% (29/40) and 31.0% (9/29) respectively.

CONCLUSIONXMG could improve the clinical symptoms with high efficacy and low relapse rate, shows a better effect than that of anticandine in treating HIV/AIDS oral candidiasis.

The evolution of hepatocellular carcinoma (HCC) is a compound process which involves many kinds of genes and transductional pathways. The expression of the peptidyl-proplyl-isomerase PIN1 gene, the mutation in exon 3 of beta-catenin and its correspondent abnormal expression and their roles in the hepatocellular carcinogeneisis were investigated. Among 29 pair cases of HCC and non-carcinoma tissues, the expression of PIN1 gene was detected by immunochemical staining. Mutations in exon 3 of beta-catenin gene and differential expression of beta-catenin gene were investigated by the methods of PCR-SSCP, direct sequencing and immunohistochemical technique as well. The results indicated: (1) 44.8% (13/29) cases of HCC presented higher level of PIN1 gene expression than non-cancerous tissues (chi2=32.63, P<0.05), especially in cytoplasm and nucleus, while there was lower level of PIN1 expression in non-cancerous tissues; (2) 58.6% (17/29) HCC tissues showed beta-catenin protein accumulation in cytoplasm and nucleus. 46.2% (6/13) HCC tissues indicated beta-catenin protein accumulation with higher level of PIN1 expression, while 53.8% (7/13) HCC tissues indicated beta-catenin protein accumulation with lower level or trace of PIN1 expression (chi2=0.00, P>0.05); (3) 24.1% (7/29) of primary tumor lesions carried gene mutations in exon 3 of beta-catenin, and accompanied by beta-catenin protein accumulation. There was no mutation in non-cancerous tissues. All the mutation presented in tissues with low level of PIN1 expression. There was no mutation of beta-catenin gene in tissues with high PIN1 expression level (chi2=58.12, P<0.05). So it was postulated that the increase of PIN1 gene expression could promote hepatocellular carcinogenesis via a way different from beta-catenin gene mutation.

Objective To observe dopamine transporter (DAT) binding capacity using 99Tcm-TRODAT-1 in drug-naive patients with Tourette's syndrome (TS) on SPECT imaging, and explore possible correlations between 99Tcm-TRODAT-1 uptake ratio and TS patient's age, disease duration, and tic severity.Methods Eighteen drug-naive TS patients, male 14, female 4, as well as 8 age- and gender-matched healthy subjects were recruited. Brain SPECT imaging was performed 2. 5 h after intravenous injection of 11.1 - 14.8 MBq/kg 99Tcm-TRODAT-1. ROI was drawn on the striatum including its sub-regions of caudate and putamen, with cerebellum as the background. Striatum/cerebellum ratio was calculated. Comparisons of the ratios between TS patients and controls were carried out by independent-sample t-test. Pearson correlation analysis was performed between DAT uptake ratios of striatum and patients' age, disease duration, tic severity. Results Compared with the control, higher symmetrically striatum uptake of 99Tcm-TRODAT-1 in TS patients was observed (2.17±0.23 vs 1.87±0.24, t =2.957, P＜0.05). Age (r= -0.320, P＞0.05)and tic severity(r = 0. 345, P ＞ 0.05) scores were not significantly correlated with specific uptake ratios measured in the striatum. But there was significant negative correlation between disease duration and the specific uptake ratios (r = - 0. 483, P ＜ 0. 05). Conclusions 99 Tcm-TRODAT-1 SPECT imaging may play an adjuvant role for initial evaluation of untreated TS.

OBJECTIVETo observe the pinching action to the nerve root by the lumbar disc herniation and facet or lamina (ligamentum flavum) and evaluate its clinical meaning.

METHODSSeventy-one patients were divided into 3 groups according to the size of distance between protrusion of nuclear and facet or lamina (ligamentum flavum). The degree of the straight leg raising of the affected side (SLR) and the sagittal index (SI) of lumbar disk herniation were measured and analyzed among them.

RESULTSThere was no corelation between the affected degree of SLR and sex, age and SI of patient (P > 0.05). The coefficient between distance group and the affected degree of SLR is-0.878 7 (P < 0.01).

CONCLUSIONThe degree of the surrounding compression by the protrusion of nuclear and facet or lamina (ligamentum flavum) reflects the injuried severity of the nerve root.
