Objective To investigate the expression of CK19mRNA and CD44mRNA in peripheral blood of patients with breast cancer for forecasting micrometastasis. Methods Expression of CK19 and CD44 were detected in 107 patients by RT-PCR method. Results CK19 and CD44 were positive in 31.8%(34/107) and 32.7%(35/107) of patients with breast cancer 24 hours before surgery respectively,which were statistically different from that of 12 days postoperatively and that of normal controls (all P

The morbidity of diabetes has been increasing rapidly in recent years. Delayed wound healing has become a common complication in diabetes, which seriously affects the orthobiosis of patients. Exploring and finding the molecular mechanisms of diabetic wound healing and the effective therapies to promote wound healing have important clinical significances. Stem cells transplant has become a research hotspot in accelerating diabetic wound healing. This article reviewed the present approaches concerning stem cells transplant in diabetic wound healing both at domestic and abroad, and looked forward the clinical therapy of stem cells on diabetic wound healing.

Objective To explore status quo of Shanghai community health services based on the investigation of rural community doctors in Shanghai suburb,and to propose measures on training rural doctors. Methods Retrospective investigation was carried out in 114 rural community health service centers and 1 563 clinics.Primary investigation included the registration,distribution,age,academic titles and education background. Results The results showed insufficient number of human resources and inadequate investment in human capitals in the primary medical services of Shanghai suburbs,and there was a serious shortage of general practitioners.The other problems included older age,insufficient academic qualifications,and without professional titles. Conclusion We should improve the status and treatment of rural doctors.Job training and well-trained professional students should be encouraged for the primary health services.More and more doctors should be attracted to work in community health service centers.General practitioners' personnal information network and general medical training network should be established,and the general medical education system gets improvement.

Objective To explore the relationship between structure and function in the diseases of posterior visual pathways as well as the anatomic mechanism of the abnormal visual responses.Methods Eleven cases of diseases of posterior visual pathways(3 gliomas,4 meningiomas,3 metastasis,1 stroke) involving either cortical or subcortical visual pathways were investigated by combining fMRI and DTI.fMRI was performed by using flashing checkerboard at 8 Hz.For imaging processing,fMRI analysis was performed with SPM99,and DTI and tractography with DTVⅡ.Fractional anisotropy(FA) of optic radiations and activated volume(VOXELs) of primary visual cortices(V1 and V2) were measured and analyzed at the affected side and the contralateral side.Relative FA(rFA) and relative activated volume(rVOXELs) were also calculated.3D tractography of optic radiations was performed successfully in 11 patients.Results In the patients with brain tumors,FA values in the affected side of optic radiations were significantly different with the contralateral side(P

OBJECTIVETo explore the effect of Jiawei Yupingfeng Powder (JYP) on T-lymphocyte subsets in patients with senile chronic bronchitis in acute onset stage (SCB-AOS).

METHODSPatients were divided, according to the randomized controlled principle, into two groups, the 44 patients in the treated group and the 40 in the control group. The conventional western medicinal therapy was given to both groups, but to the treated group, JYP was administered additionally. The therapeutic course to them was 14 days. Changes of CD3, CD4, CD8 and the ratio of them were observed.

RESULTSIncrease of CD3, CD4 and CD4/CD8 (P < 0.05) and decrease of CD8 (P < 0.01) were significantly shown in the treated group after treatment, but no change in the control group. Besides, comparison of the total effective rate in the two groups also showed significant difference (P < 0.05).

CONCLUSIONCellular immune function disturbance exists in patients with SCB-AOS, JYP could enhance the efficacy by way of modulating cellular immune function.

Objective To investigate the effect of isoflurane on the levels of protein kinase A (PKA) and protein kinase C (PKC) in hippocampus in rats. Methods Thirty-six 3-month-old male SD rats weighing 180-220 g were randomly divided into 3 groups ( n = 12 each): group Ⅰ underwent the cognitive function test without being pretreated with isoflurane inhalation (group C); group Ⅱ and Ⅲ inhaled 1.2% isoflurane for 4 h and underwent the cognitive function test 2 days and 2 weeks later respectively (group Ⅰso1,Iso2). Morris water maze was used to assess the cognitive function and the escape latency was recorded. The animals were killed immediately after the test.The hippocampus was isolated for determination of the expression and activities of PKA and PKC.Results The escape latency was significantly longer in group Ⅲ than in group Ⅰ.The expression of PKA and PKC was significantly down-regulated and the activities of PKA and PKC were significantly decreased in group Ⅱand Ⅲ as compared with group Ⅰ . There was no significant difference in the expression and activities of PKA and PKC between group Ⅱ and Ⅲ . Conclusion Four hour 1.2% isoflurane inhalation can decrease cognitive function by inhibiting the levels of PKA and PKC in hippocampus.

Objective To examine the suscepribility of the single nucleotide polymorphisms(SNPs)in IL-1 gene in Chinese Han population to ankylosing spondylitis (AS). Methods An correlation analysis was performed in a case-control cohort of 162 AS cases, 58 patients with other autoimmune diseases and 162 controls. Four SNPs located in the IL-1 gene (rs16944, rs3811058, rs419598, rs315952) were examined by polymerase chain reaction restriction fragment length polymorphism(PCR-RFLP). Results The frequencies of allele C at position rs16944, rs3811058, rs419598 significantly increased in AS cases VS controls, so did their genotype frequencies (50% vs 36.3%, 57.9% vs 52.8%, 45.7% vs 12.3%, P＜0.05). The SNPs of these sites significantly influenced the prevalence of AS. Conclusion We discover that SNPs of IL-1 gene Rs16944, Rs419598, Rs3811058 is closely related to the occurrence of AS.

ObjectiveTo observe the effects of D-limonene on lymphangiogenesis and lymph node metastasis in breast cancer. Methods Human breast cancer cell lines MDA-MB-435 were implanted into the mammary fat pad of 24 female nude mice to establish breast cancer model. The tumor volume and the incidences of lymph node metastasis were detected. Immunohistochemical staining was used to detect the lymphatic microvessel density and VEGF-C expression of the breast cancer tissues. Results In D-limonene group, tumor volume(0.824?0.31) and incidences of lymph node metastasis(25.0%) were significantly inhibited compared with control group (2.178?0.35,87.5%)(all P
