Objective To explore the relationships between cholangiocarcinoma and clonorochiasis or hepatolithiasis,and to compare their MRI features.Methods The MRI features in 37 patients with cholangiocarcinoma confirmed by surgery and pathology were retrospectively analyzed,including clonorchiasis with cholangiocarcinoma in 21 (group A)and hepatolithiasis with this tumor in 16 (group B).The analyzed parameters included the location,size,shape,signal intensity and enhancement pattern of the tumor and the characteristics of bile duct dilatation.Results In group A,the tumors were located in the right lobe in 12 (57.2%),left lobe in 4 (19%),and porta hepatic in 5 (23.8%).In group B,those were located in the right lobe in 3 (18.7%),left lobe in 9 (56.3%),and porta hepatic in 4 (25%).There was a significant difference in the left/right lobe between two groups (P<0.05),however,no significant difference was found in porta hepatic (P>0.05).The MRI showed the tumors with low signal on T1 WI and high or heterogeneous signal on T2 WI,and with peripheral enhancement in early stage and delayed centric enhancement in 34 patients.Diffuse saccular dilatations of terminal intrahepatic bile ducts were showed in 1 6 (7 6 .2%)in group A and 1 (6 .2%)in group B,meanwhile the dilatations of bile ducts within tumors were showed in 2 (9.5%)in group A and 13 (81.3%)in group B,exhibiting significant differences between the two groups (P<0.05).Conclusion Clonorochiasis and hepatolithiasis are related with the cholangiocarcinoma.No differences in MRI features of cholangiocarcinoma are found between the two groups,however significant differences in location and the features of bile duct dilatation are observed.

Objective To detect the expression of promyelocytic leukemia(PML)gene in peripheral blood lymphocytes from patients with psoriasis vulgaris,and to investigate the relationship between PML gene and psoriasis.Methods This study included 50 patients with vulgaris psoriasis who were aged between 18 and 65 years and had never received systemic treatment,as well as 45 healthy controls.Peripheral blood samples were collected from these subjects,and lymphocytes were separated by density-gradient technique.Then,RNA was extracted from the lymphocytes by using RNAprep pure blood kit followed by real time fluorescence-based quantitative reverse transcription-PCR for the detection of PML mRNA expression.Flow cytometry was performed to quantify the expression of PML protein in the lymphocytes.Independent samples t test was carried out to compare the differences in PML expression between the patients and controls.Results The relative quantity (RQ)of PML mRNA was 14.98 ± 3.64 in peripheral blood lymphocytes from the patients,significantly higher than that in the healthy controls(5.50 ± 1.10,t =16.79,P < 0.05).Similarly,a significant increment was observed in the fluorescence intensity of PML protein in peripheral blood lymphocytes from the patients compared with the healthy controls(3.13 ± 0.27 vs.2.43 ± 0.21,t =6.93,P < 0.05).Conclusions PML is overexpressed at the protein and mRNA levels in peripheral blood lymphocytes from patients with psoriasis vulgaris,hinting that PML may play a certain role in the development of psoriasis.

In this paper, issues of acupuncture using target points and depth of needling were discussed based on the theory of traditional Chinese medicine acupoints and combined with anatomical and neurological research of Western medicine. The theoretical evidence of acupuncture on nerve foramen and ganglion and the reasons for being nonstandard operating on acupoints were analyzed. This study summarized the method of using acupuncture at Xiaguan (ST7), Cuanzhu (BL2), Sibai (ST2) and Jiachengjiang acupoints to align with the spheno-palatine ganglion and additional nerve foramen (supraorbital, infraorbital and mental foramina) to treat primary trigeminal neuralgia. This study adhered to the Standards for Reporting Interventions in Clinical Trials of Acupuncture and helped in development of study standardization for acupuncture processes. The authors hoped that should help in significantly diminishing risk and improving therapeutic efficacy in clinic.

Objective To investigate the relationship between cysteine-rich protein 61 ( Cyr61 ) and phosphatidylinositol 3-kinase ( PI3K ) signal pathway on cell proliferation and apoptotic in human ovarian carcinoma cells.Methods Recombinant human Cyr61 (rhCyr61) was pretreated with ovarian carcinoma cells.The expression of Cyr61 protein was detected by confocal spectral microscopy.Then treated the ovarian carcinoma cells with PI3K transduction inhibitors (LY294002) for 24 hours.Cell apoptosis was detected by flow cytometry (FCM).Cell viability was determined by methyl thiazolyl tetrazolium (MTT) method.The mRNA expressions of Cyr61,the protein levels of protein kinase B ( PKB),phospho-PKB and Cyr61 were assaved by real time-PCR and western blot analysis,respectively.Results The Cyr61 and phospho-PKB protein expression in two ovarian carcinoma cells (OV2008 and OVCAR-3 ) were increased in rhCyr61pretreated group.The decreasing of cell apoptosis [ ( 1.4 ±0.9)%,(2.1 ± 1.0)% ] and increasing of cell proliferation [ ( 124.0 ± 1.8)%,( 133.0 ±2.2)% ] was detected in the same time,compared with negative control group,there were significant difference ( P < 0.05 ).After exposed to LY294002 for 24 hours,the apoptosis rate of OV2008 and OVCAR-3 in pretreated with rhCyr61 group exposed to LY294002 were (21.1 ± 1.6)% and (26.4 ± 1.5 )%,respectively.Cells viability [ (59.0 ± 2.3 )%,(51.0 ± 2.0)% ]was also significantly decreased in OV2008 and OVCAR-3 pretreated with rhCyr61 cells.Meanwhile,the mRNA expressions of Cyr61 (3.2 ± 0.8,6.2 ± 1.1 ) and the protein levels of phospho-PKB and Cyr61 were greatly decreased.Compared with negative control group,there were significant difference in OV2008 and OVCAR-3 cells (all P < 0.0l ).Conclusions The activation of PI3K intracellular signaling pathways may lead to up-regulation of Cyr61 expression.Block PI3K signal pathway could significantly inhibit the expression of Cyr61,and may promote the apoptotic effects and inhibit the cell growth of ovarian carcinoma cells.
