This study was aimed to compare the function of dendritic cells (DCs) in patients of Y in-Huang syn-drome and Y ang-Huang syndrome from the peripheral blood of HBV related hepatic failure. Jaundice patients of HBV related hepatic failure were divided into two groups, which were the Y ang-Huang syndrome group and Y in-Huang syndrome group. And a healthy control group was also established. The DCs were separated and cultured in vitro from PBMCs in the peripheral blood. Surface molecules such as HLA-DR, CD80, CD86, CD83 and CD1αwere detected by the flow cytometry. And the level of IFN- α and IL-4 in the supernatant of DCs were also de-tected. The expression difference of inflammatory cytokines and immune cells between Y in-Huang and Y ang-Huang syndrome in patients of HBV related hepatic failure were compared. The results showed that compared with healthy people, the expression rate of DCs phenotype such as HLA-DR, CD1α, CD83, CD80, CD86 in patients of HBV related hepatic failure was significantly decreased (P < 0.01); the excreted factor IFN-α had a significant rising (P < 0.01). Compared to Y ang-Huang syndrome group, the expression rate of CD83 and CD86 in the Y in-Huang syndrome group of HBV related hepatic failure patients was significantly reduced (P < 0.01). And the ex-creted factor of IL-4 had a significant rising in Y in-Huang syndrome group (P < 0.01). Compared to the Y in-Huang syndrome group, the excreted factor IFN-α in the Yang-Huang syndrome group had a significant rising (P< 0.01). It was concluded that DCs function of patients with HBV related hepatic failure in both Y in-Huang syn-drome and Y ang-Huang syndrome group showed low immune function. And the immune function of the Y in-Huang syndrome group was lower. There was excessive releasing of inflammatory factors in the Y ang-Huang syn-drome group. And there was enhanced anti-inflammatory cytokine expression in the Y in-Huang group.

OBJECTIVETo study the different effect of needling at different meridian points (MP) on different cerebral functional regions by using positron emission tomography and cerebral function tracer 18F-fluorodeoxy glucose to observe the effect of electro-acupuncture (EA) stimulation at Yin MP or Yang MP on local cerebral glucose metabolism in 30 healthy volunteers.

METHODSThe thirty subjects were randomly divided into 2 groups, the 12 subjects in the Yang MP group treated by needling at Hegu (LI4), Quchi (LI11), Zusanli (St36) and Shangjuxu (St37), the 18 subjects in the Yin MP group treated by needling at Neiguan (Pc6), Chize (Lu5), Sanyinjiao (Sp6) and Yinlingquan (Sp9). All the needling was conducted at one side of body.

RESULTSAfter needling at Yang MP, the cerebral glucose metabolism was elevated in bilateral cross region of frontal lobe and temporal lobe, parietal lobe, thalamus and basal ganglia, and in contralateral cerebellum and hippocampus. After needling at Yin MP, the cerebral glucose metabolism was lowered in bilateral cross region of frontal and temporal lobe, contralateral temporal lobe, cerebellum and thalamus, and was elevated in homolateral hippocampus and caudate nucleus.

CONCLUSIONUnder physiological condition, the regulatory effects of acupuncture on central nervous system would be different when needling at different MP.

Objective To discuss the feasibility and application value of probe-based confocal laser endomicroscopy(pCLE)for differential diagnosis of maligant biliary stricture. Methods The pCLE images of 10 patients with definite biliary structure were retrospectively analyzed to establish pCLE classification of biliary lesions, and then the patients, who accepted pCLE examination and traditional brush cytology successively,were selected for further prospective research. Each patient was scored in terms of sign of malignant lesion to analyze diagnostic efficacy of combinations of different signs using classification standard of pCLE image. The results were compared with cell brushing test. The diagnostic consistency of observers using pCLE was also evaluated. Results A total of 25 patients completed the prospective research. When patients presented with any two or more malignant signs,diagnostic efficacy of pCLE was best with accuracy rate of 84.0%(95%CI:64.7%-94.2%),and sensitivity,specificity,positive predictive value and negative predictive value was 87.5%(95% CI: 62.7%-97.8%), 77.8%(95% CI: 44.3%-94.7%), 87.5% (95%CI: 62.7%-97.8%), and 77.8%(95% CI: 44.3%-94.7%), respectively. The corresponding indicators of brush cytology was 56.0%(95% CI: 37.1%-73.4%), 31.3%(95% CI: 13.9%-55.9%), 100.0%(95%CI:65.5%-100.0%),100.0%(95%CI:51.1%-100.0%),and 45.0%(95%CI:25.8%-65.8%),respectively,and the sensitivity(P=0.001)and accuracy(P=0.03)were significantly lower than that of pCLE. The κ value of interobserver agreement level was 0.73, which revealed a significant consistency. Conclusion pCLE provides a new approach for the differential diagnosis of biliary stricture, and shows a potential clinical application value.

Objective To study the influence of fluoride on the expression of osteoprotegerin(OPG) mRNA and protein in suckling rat osteoblasts. Methods Osteoblasts obtained from calvarial of suckling Wistar rats were cultured in vitro in the media supplemented with NaF at a series of doses[O(control), 1,2 and 4 mg/L groups], and OPG mRNA expression and protein were evaluated by RT-PCR and ELISA methods, respectively. Results OPG mRNA expression in suckling rat osteoblasts cultured in vitro significantly increased after exposure to NaF for 48 h and 72 h(F=333.48,808.34,P<0.05). OPG mRNA expression in suckling rat osteoblasts cultured in vitro after exposure to NaF for 48 h at different doses(0.810±0.003, 0.819±0.031 and 0.870±0.044 for 1,2 and 4 mg/L groups, respectively) compared with that of control (0.800±0.040, all P<0.05). OPG mRNA expression further increased for 72 h exposure to NaF(0.933±0.047,1.031±0.051,1.240±0.062 for 1,2 and 4 mg/L, respectively), significantly higher than that of the control (0.805±0.020,all P<0.05) and corresponding groups at 48 h. NaF doses and time exposure exhibited a significant synergistic effect on OPG mRNA expression(F=2004.16, P<0.05). NaF also enhanced OPG protein expression in suckling rat osteoblasts cultured in vitro. Significant differences were observed only in 4 mg/L group(0.228±0.014,0.277±0.048) and control(0.205±0.012,0.229±0.010) at 48 h and 72 h (P<0.05). In addition, OPG protein expression at 72 h post-exposure was higher than that at 48 h,but there was no synergistic effect between concentration and time(F=1.21,P>0.05). Conclusions The results suggested that NaF could increase OPG mRNA and protein expression in suckling rat osteoblasts with a synergistic effect between the doses and exposure time.

Objective To study the characteristics of brain electrical signals in mild cognitive impairment (MCI) patients and healthy elderly volunteers in rest and task loading state.Methods Twenty MCI patients served as a MIC group and 22 sex-,age-and education-matched healthy volunteers served as a control group in this study.The patients were scored according to the MoCA,HADS,MMSE and CMS,their brain electrical signals in a different state were recorded with a digital EEG recording device,and their Lemple-Zie complexity (LZC) was computed on the MATLAB 7.04 platform and comparatively analyzed.Results The MQ value and MoCA,HADS,MMSE,CMS scores were significantly higher in control group than in MCI group (P＜0.01).The LZC value in left frontal region and left temporal region was significantly higher in control group than in MCI group in rest state (0.577±0.059 vs 0.545±0.067,0.576±0.061 vs 0.548±0.059,P＜0.05).The LZC value in right frontal region and right hemisphere was significantly lower in MCI group than in control group in brain electrical activity state (0.535±0.065 vs 0.559±0.033,0.541±0.064 vs 0.551±0.047,P＜0.05).The LZC value in left frontal region,left temporal region,left hemisphere was lower in control group than in MCI group (0.523±0.040 vs 0.547±0.070,0.547±0.048 vs 0.561±0.092,0.542±0.044 vs 0.557±0.067,P＜0.05).Conclusion The LZC value is lost in the left hemisphere but its functional compensation is present in the right and Left parietal lobe,left frontal lobe and right brain areas in MCI patients in a non-linear manner.

In order to investigate the effect of antisense oligonucleotide (ASODN) of vascular endothelial growth factor C (VEGF-C) on lymphangiogenesis and angiogenesis of pancreatic cancer, antisense and scamble-sense oligonucleotide of VEGF-C were constructed, and the model of nude mice with orthotopically xenografted human pancreatic cancer cells (Panc-1) was established. Thirty nude mice were randomly divided into 3 groups: PBS control group (group A), scramble-sense control group (group B) and antisense group (group C). All nude mice were treated once every 2 days as 3 times per week, for 3 weeks (oligonucleotide 10 mg/kg every time). After treatments were completed, ELISA method was used to examine the concentration of VEGF-C in plasma and immunohistochemical method to examine microvessel density (MVD), lymphtic vessel density (LVD) of pancreatic cancer. The results showed that the expression of VEGF-C was inhibited significantly in group C. The concentrations were 237.5±41.5, 221.5±52.3 and 108.6±14.9 pg/mL in groups A, B and C respectively (P＜0.01). LVD in groups A, B and C was 13.8±2.1, 12.4±1.9 and 4.2±1.6 respectively (P＜0.01). MVD in groups A, B and C was 27.5±8.7, 25.9±4.2 and 19.4±5.6 respectively with no significant difference among the groups (P＞0.05). It was suggested that VEGF-C ASODN decreased the expression levels of VEGF-C in nude mice with orthotopically xenografted human pancreatic cancer, and it could inhibit lymphangiogenesis, but had no significant effect on angiogenesis.
