Objective: To analyze the efficiency and differences of China Community Health Service, to analyze the shares of eastern-middle-western regional differences and the difference within each region in the total efficiency difference. Methods: The super efficiency DEA model and decomposition of Gini coefficient by Subgroups are used to analyze the provincial data in China from 2008 to 2011. Results: The eastern-central-western regional difference is the major cause of the efficiency differences in China Community Health Service. In the meantime, the shares of the difference within each region in the total efficiency difference are also non-negligible. Conclusion: To narrow the efficiency differences among eastern, central and western areas; improve the inter-regional flow of community health service resources; improve the support and supervision on the backward regions; make regional policies to coordinate the internal resources of community health services and strengthen the assessment mechanism using efficiency as the indicator.

Transcatheter closure as an alternative to medical surgery has become a preferred therapeutic method to atrial septal defect (ASD).However,thrombopoiesis after occluder implantation has been reported comprehensively and causes a series of serious complications such as cerebral embolism、myocardial infarction,pulmonary embolism and so on.Reasons of device thrombopoiesis are closely associated with atrial fibrillation,persistent atrial septal aneurysm,occluder type,activated coagulation system and occluder endothelialization process.This paper summarizes correlation factors of occluder thrombopoiesis and current related prevention proposal after transcatheter closure of ASD,and provides theoretical and experimental foundation for prevenition of device thrombopoiesis after occluder implantation of ASD.

Nco-adjuvant endocrine therapy has provided opened new alternatives for locally advanced breast cancer, especially for patient groups such as the elderly, those who are not suited for chemotherapy, and those whose response may not be optimal. The latest generation of endocrine therapy for breast cancer,aromatase inhibitors, has proved superior to tamoxifen in terms of toxicity and efficacy in the adjuvant setting.Compared with neo-adjuvant chemotherapy, the appropriate patients to receive nco-adjuvant endocrine therapy can achieve similar short-term benefit. However, because of fewer long-term follow up results, the overall prognosis is not clear.

New technologies and ideas are constantly emerging recently. With the arrival of the era of minimally invasive surgery, most of the colorectal cancer surgeries can be conducted through minimally invasive techniques. In this study, we discuss the status, characteristics, controversy, and consensus of minimally invasive techniques in colorectal cancer surgery.

Long-term failure in choice of materials for artificial esophagus (AE) and in treating incidence of postoperative com-plications of esophageal cancer has resulted in lack of ideal AE regeneration. As one of the innate elements forming the human body, carbon possesses high tissue affinity. Artificial esophagus as the induced stent of esophageal regeneration is the best choice for replac-ing esophageal defects and for reintroducing oral feeding after cancer radical resection.

Objective To observe the autofluorescence (AF) manifestation in related lesions of periphery retinopathy. Methods Sixty eyes of 42 patients with periphery retinopathy underwent the examination of Optomap fundus photograph (200°) and fundus fluorescein angiography (FFA). The HRA Ⅱ melanin-related near-infrared fundus autofluorescence (NIA, excitation 795 nm) and lipofuscin-related fundus autofluorescence (FAF, excitation 488 nm) were measured for all the patients. The AF was recorded with nine images per second, and then a final AF image with 55° view and 822 × 768 pixel was generated by the HRA. AF images can be valuable or valueless if there was or was not visible blood vessels and related retinal tissues on the image. AF from lesion regions can be normal or abnormal fluorescence comparing to the normal vascular and retinal tissue AF. The abnormal fluorescence was divided into no AF, weak AF and strong AF relative to the background grayscale. The grading consistency of abnormal fluorescence based on FAF and NIA examination was comparatively analyzed. Results Valuable AF images were captured in 53/60 eyes (88. 33%)and valueless AF images were captured in 7/60 eyes (11.67%). Among 53 eyes with valuable AF image, NIA showed normal fluorescence in 28 eyes (52. 83%), abnormal fluorescence with sheet-like, dot-shaped or stripped in 25 eyes (47.17%); FAF showed normal fluorescence in two eyes (3.77 % ), abnormal fluorescence with sheet-like, scattered along vessels or pigments in 51 eyes (96.23 % ).Twenty-five eyes with abnormal fluorescence were observed both in two examinations, including same grades in 18 eye (72.00%) and different grades in seven eyes (28.00%). Conclusion The AF manifestation with different levels exists in related lesions of periphery retinopathy.

Objective To investigate the significance of human cyomeg Movirus(HCMV)pp65 IgG antibody avidity index(AI)for the clinical diagnosis of HCMV primary infection through the experimental model of HCMV primaly infection in BALB/c mice.Methods 6～8 weeks,female,specific-pathogen-free BALB/c mice were divided into 5 groups.6 mice in each group. And he mice were injected with 2×106 PFU/m1,2×105 PFU/mi,2×104 PFU/ml,2×103 PFU/ml and 2×102 PFU/ml of HCMV intraperitoneally respectively. Another 6 mice were injected intraperitoneally with the maximum dose of HCMV kept at 56℃ for 30 min as inactivated virus group.And HF negative control group was established at same time. All the mice ere sacrificed to obtain brain and lung tissues for the following experiments after 1 montll.(1)Tissue samples obtained from mice were inoculated in human embryo fibroblasts(HF)monolayers after routine treatment for virus isolation.HCMV specific eytopathie effect(CPE) was observed bv inverted phase-contrast microscopy.HCMV UL83 DNA in the ultures as tested by PCR and pp65 antigen was detected by indirect immunofluorescence.(2)Extracted mRNA from tissue samples and HCMV pp67 mRNA were analyzed by reverse transcriptase PCR(RT-PcR).(3)Immunoglobulin M(IgM)antibody and immunoglobulin G(1gG)antibody avidity Was investigated for their usefulness in distinguishing primary genital HCMV infections rom nonprimary infections with ELISA kit using truncated pp65 protein.ResultsHCMV can be isolated in the tissues from the mice injected with 2×106 PFU/ml and 2×105 PFU/m1.RT- PCR and ELISA showed positive results in the same groups.The infective rates were 100%.The analysis of the low doses groups,inactivated group and HF negative ontrol group all showed negative results.Conclusions BALB/c mice can be infected with HCMV and appeared as primary infection after1 month.Determination of HCMV pp65 IgM and HCMV p065 IgG-AI by ELISA incorporated with virus isolation and RT-PCR are helpful for distinguishing primary infections from nonpfimary infections.The detection of HCMV p65 IgM and HCMV pp65 IgG-AI by ELISA utilizing recombinant protein pp5 as antigens can be used for preliminary screening.

Objective To study the association of apolipoprotein ( Apo) E gene polymorphism with difference in biochemical metabolism of diabetic nephropathy of Hui and Han populations. Methods ApoE genotype was determined by PCR-RFLP in diabetic patients with or without diabetic nephropathy (DN) and normal peoples in Hui and Han peoples, the related biochemical parameters were simultaneously detected. Results (1) Huis had 3 genotypes, i. e. E2/E3, E3/E3 and E3/E4, and their frequencies were 0. 043, 0. 894 and 0. 064, respectively. Hans had 5 genetypes, i. e. E2/E2, E2/E3 , E2/E4, E3/E3 and E3/E4, and their frequencies were 0.075,0.060, 0.164, 0.642 and 0.060, respectively. The frequencies of 3 alleles, E2, E3 and E4, in Huis and Hans were 0.021, 0.947, 0.032 and 0.187, 0. 702, 0.112, respectively. The results showed that difference in frequencies of genotypes and alleles of Huis and Hans was very significant (both P
