Objective There is a significant increase of squamous cell carcinoma antigen ( SCCA) in patients with common skin diseases .The aim of this study was to investigate the difference expression of serum SCCA in patients with common skin diseases . Methods A total of 497 patients with 14 kinds of common skin diseases from the Department of Dermatology were recruited , and the serum SCCA was measured . Results The positive rates of SCCA in 116 patients with psoriasis and 37 patients with erythroderma were 90 .5% and 100%, respectively .The common skin diseases with positive rate of SCCA greater than 60% includes eczema (61.7%), generalized dermatitis (65.1%),pemphigus (61.1%), bullous pemphigoid (62.2%).The SCCA values in pustulosa (1.76 ±1.22 ng/mL) and arthropathica psoriasis (1.69 ±1.05 ng/mL) were decreased compared with pustular (2.86 ±1.46 ng/mL) and arthropathica psoriasis (3.56 ±1.84 ng/mL) (P<0.05). Conclusion The SCCA value may have a relationship with the increase of the performance of keratinization and desquamation in the skin diseases , and it could be used as a valuable indicator for the diagnosis and treatment in patients with cutaneous diseases .

Objective To investigate the efficacy of acupoint injection of Astragalus on contents of SOD,HYP and MDA in skin of aging mice in-duced by D-galactose. Methods The mice were randomly divided into normal group,model group,Astragalus group,and saline group(n=15). Except for the normal control group,the mice of other groups were treated with continuous subcutaneous injection of D-galactose to establish mice ag-ing model. The Astragalus group mice was injected with 0.01mL Astragalus in Sanzuli acupoint per day,The saline group mice received an injection of same amount of saline. SOD,HYP and MDA changes in the skin tissue and serum were evaluated after 21 days. Results All the index in the skin tissue and serum showed significant difference(P<0.01)between model group mice and normal control group. Compared with model group,SOD activity and MDA content in the skin tissue and serum of the Astragalus group mice were significantly raised,HYP content was significantly reduced (P<0.01). There also were significant differences of these index between the saline group mice and the model group(P<0.05),but the effect was not as good as the Astragalus group mice. Conclusion Acupoint Injection of Astragalus can prevent and protect against skin aging induced by D-galactose.

Objective To compared the condition of DSA and MRA for detection the lesion vessels in elder patients with recurrent ischemic cerebrovascular disease(ICVD).Methods 52 patients with ICVD,including 41 cases of cerebral infarction(CI) and 11 cases of transient ischemic attack(TIA) were detected by DSA,and the 44 cases of them were detected by MRA too.Results The vascular anomalies were detected in 43 cases(82.69%) of the 52 patients by DSA.Among them,39 cases(75%) had vascular stenosis,in which 31 cases(75.61%) were CI,and the other 8 cases(72.73%) were TIA.The aneurysm were founfd out in 2 cases,and vascular dysplasia and variation were also found in each 1 case by DSA.The vascular stenosis were found in 10 cases(22.73%) of 44 patients by MRA,in which 8 cases(18.18%) were CI,while 2 cases(4.55%) were TIA.The detection rate of lesion vessels in DSA was significantly higher than that in MRA(P

Objective The study was to investigate the value of deduction and application of anterior compression index in evaluation of atlantoaxial dislocation and restoration. Method Twenty-eight cases of the control group and 28 cases of atlantoaxial dislocation treated with posterior restoration and screw-rod internal fixation technique before and af?ter surgery were recruited in this study and their data was retrospectively analyzed. All of the people underwent sagittal computerized tomography scan films. The anterior compression index was measured in all cases. Results The mean value of anterior compression index of the control group was 87.86±24.98. The mean value of anterior compression index of the preoperative patients was 230.44 ± 97.60 and the mean value of the postoperative patients was 106.27 ± 73.53. There was significant difference in those two parameters between the preoperative patients and the controls(t=-7.50,P<0.0001). There was no significant difference between the postoperative patients and the control group (t=-1.26, P=0.2171). Anteri?or compression index were significantly lower after surgical operation (t=10.35, compared with before, P<0.0001). Con?clusion Anterior compression index can be an excellent measurement tool for the assessment of relationship of atlas and axis in atlantoaxial dislocation patients before and after posterior restoration operation.

Objective:Bone marrow-derived dendritic cells ( DCs) were extracted and gave tanshinone ⅡA to intervene ,and we observed the change of DCs function ,which investigate the effects of tanshinone ⅡA in immune system.Methods:Extract bone mar-row-derived DCs,and cells were cultured in complete medium with 10 ng/ml GM-CSF and IL-4.On day 5,magnetic cell sorting was used to purify DCs,and the purify must be up to 90%.Then,a certain concentration of tanshinone ⅡA or LPS was gave to the cell cul-ture,and cells and supernatant were collected for following experiments .We used flow cytometry to detect phenotype , and enzyme-linked immunosorbent assay(ELISA) was used to detect cytokine production of TNF-αand IL-12.Also,allogeneic mixed lymphocyte reaction was used to detect the ability of DCs to induce T cell proliferation and polarization .Results:When the concentration of tanshi-none ⅡA was 500 ng/ml,the inhibition of secretion of TNF-αwas maximal.So we chose that concentration .Compared with the control group,DCs in experimental group had reduced expression of CD 80,CD86 and MHCⅡ(P<0.05).Compared with the control group ,DCs in experimental group displayed the reduced level of IL-12 and TNF-α(P<0.05).Compared with the control group,DCs in experimen-tal group had reduced ability to induce T cell proliferation (P<0.05).Compared with the control group ,DCs in experimental group in-duced T cell to secret increased level of IL-4,and reduced level of IFN-γ(P<0.05).Conclusion:TanshinoneⅡA can inhibit the den-dritic cells maturation induced by LPS ,which takes part in immune system and autoimmune diseases .

The rate of complete surgical resection is still low in hilar cholangiocarcinoma,which greatly affects the curative effect.Radiotherapy,one kind of treatment for tumors,has not been widely adopted in the past years.In recent years,with the development of radiotherapy technology,research of treating hilar cholangiocarcinoma through radiotherapy has become a spot.Many studies have shown that radiotherapy,as an adjuvant therapy for surgery and non-surgical treatment,can be the major means for treatment,and it could bring benefit for patients' survival extension and improvement of life quality.

Hyoscyamine 6 beta-hydroxylase (H6H) is the last rate-limiting enzyme directly catalyzing the formation of scopolamine in tropane alkaloids (TAs) biosynthesis pathway. It is the primary target gene in the genetic modification of TAs metabolic pathway. Full-length cDNA and gDNA sequences of a novel H6H gene were cloned from Datura arborea (DaH6H, GenBank accession numbers for cDNA and gDNA are KR006981 and KR006983, respectively). Nucleotide sequence analysis reveals an open reading frame of 1375 bp encoding 347 amino acids in the cDNA of DaH6H, while the gDNA of DaH6H contains four exons and three introns, with the highest similarity to the gDNA of H6H from D. stramonium. DaH6H also exhibited the most identity of 90.5% with DsH6H in amino acids and harbored conserved 2-oxoglutarate binding motif and two iron binding motifs. The expression level of DaH6H was highest in the mature leaf, followed by the secondary root, and with no expression in the primary root based on qPCR analysis. Its expression was inhibited by MeJA. DaH6H was expressed in E. coli and a 39 kD recombinant protein was detected in SDS-PAGE. Comparison of the contents of scopolamine and hyoscyamine in various TAs-producing plants revealed that D. arborea was one of the rare scopolamine predominant plants. Cloning of DaH6H gene will allow more research in the molecular regulatory mechanism of TAs biosynthesis in distinct plants and provide a new candidate gene for scopolamine metabolic engineering.
