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

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 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

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.

8.Therapeutic effects of cannulated compression screws for treating femoral neck fractures.
China Journal of Orthopaedics and Traumatology 2012;25(12):1040-1044
OBJECTIVETo explore the relevant factor of cannulated compression screws in treating femoral neck fractures.
METHODSFrom January 2004 to January 2011, 190 patients with femoral neck fractures treated by cannulated compression screws were analyzed retrospectively. In all of the 190 cases, there were 104 males and 86 females with an average of 65 years (ranged, 21 to 83 years). According to Garden classification system, 25 cases were type I, 51 cases were type II, 58 cases were type II and 56 cases were type IV. The time from injury to operation was 15 h to 10 d (mean 3.5 d). The gender,age, trauma type, fracture type, osteoporosis, emergency operation, fracture reduction, relation between open reduction and nonunion were observed and analyzed.
RESULTSAll patients were followed-up for 12 to 84 months, with a mean of 38 months. All incisions obtained stage I healing. There were 23 patients with bone nonunion. The rate of nonunion was 12.1%. Single factor analysis showed that there were significant differences in age, trauma type, fracture type, fracture reduction and osteoporosis (P<0.05), but no meaning in gender, emergency operation, relation between open reduction and nonunion (P>0.05).
CONCLUSIONCannulated compression screws for femoral neck fractures can obtain good outcomes, and age, trauma type, fracture type, fracture reduction and osteoporosis are main factors.

OBJCETIVETo investigate the method of separation of culture of bone microvascular endothelial cells (BMECs) of human femoral head in vitro.
METHODSFrom October 2013 to January 2014,15 femoral heads without pathologic change from patients resected during hip replacement were selected involving 2 males and 13 females with a mean age of 71.2 years old ranging from 38 to 92. Cancellous bone in femoral head was bited into broken bone grain and transfered into medium in aseptic contidion. Cells were isolated by the methods of enzymic digestion and density gradient centrifugation,purified by differiential attachment. The characteristics of cells was observed by inverted microscope. vWF and CD31 immunofluorescence analysis was applied for identification of cells.
RESULTSThe number of cells was positively correlated with patients' age after 24 hours in primary culture. The older patients had the less cells numbered. After 4 to 5 days' culture, primary cells appeared short spindle,polygon shaped and cobblestone-like morphology. After 7 to 10 days' culture, primary cells proliferated densely, became fusion, arranged in swirl, and contact inhibition appeared significantly. Immunofluorescence staining revealed the cells were 100% positive for vWF and CD31, and it showed that the cultured cells were BMECs.
CONCLUSIONIt was a simple, steady, effective method with good reproducibility, by which highly purified human BMECs can be obtained.

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.
