The United Kingdom is the longest-serving community in the welfare states, and has been serving for more than sixty years so far. The construction of community care service supply model in the United Kingdom is deeply influenced by the neo-liberalism and neo-managerialism, which dominated the reform and development of pur-chasing community care services. Presently, China is actively promoting the government to purchase pension services of public health care combined with the long-term care, especially policy and determination of community-based de-velopment of an elders' service model. Based on the purchased services experience of the United Kingdom combined with the situation in China, this paper puts forward some suggestions such as the repositioning the role of the govern-ment, actively supporting the development of civil service organizations and perfecting the legal system of care serv-ices to be purchased, supporting the development of proposals to reduce the burden on the government and enhance the efficiency of care services through improving their quality.

There has been emergence of evidence suggesting that specific variants of the vascular endothelia growth factor (VEGF) family, based on their ability to regulate angiogenesis, would be pivotal in the pathogenesis of endometriosis. This study was aimed at determining whether high levels of VEGF-A could be found in the serum and peritoneal fluid (PF) of patients with endometriosis. VEGF-A levels were measured by enzyme-linked immunosorbent assay (ELISA) in serum and PF from 46 patients with surgically confirmed endometriosis, and 40 controls with no clinical evidence of the disease or detectable endometriotic lesions at the time of surgical examination. The results showed the mean VEGF-A levels were significantly higher in the serum and PF of patients with endometriosis than in the controls. The VEGF-A levels in the serum and PF of patients with severe endometriosis (stages III-IV) were significantly higher than in those with minimal endometriosis (P<0.001). It was concluded that endometriosis was associated with significant modulation in the levels of circulating VEGF-A.

Objective To investigate the expression of specific marker molecules in hair-inducing activity of long-term cultured human dermal papilla cells (HDPCs) in vitro.Methods After dissected and cultured the HDPCs in vitro,the cells of passages 1 to 8 were used for experiments.The growth appearances of HDPCs in different passages were observed under inverted microscope.To detect the expression of specific marker molecules of long-term cultured HDPCs,the alkaline phosphatase (ALP) activity of the HDPCs was examined,and the specific genes ALP and insulin-like growth factor-1 (IGF-1) expression levels of HDPCs were determined by real-time quantitative PCR.Results After long-term cultured in vitro,the ALP and IGF-1 expression levels of HDPCs gradually decreased in different passages,as well as the display of the aggregated and cartouche growth.The ALP and IGF-1 expression levels of HDPCs in passage 1 was the highest,they were almost about 6.8-fold and 3.5-fold higher than the HDPCs in passage 8.The ALP staining of the HDPCs in passage 1 and passage 2 were evident,but the cells' ALP staining gradually became much weaker than the cells in the previous passages after the long-term cultured in vitro.Conclusions The expression levels of specific marker molecules ALP and IGF-1 of the HDPCs decrease gradually after long-term cultured in vitro,and the higher passage HDPCs lost the special aggregated and cartouche growth appearance,and hence lead to the loss of hair-inducing activity of HDPCs.

Bone defects caused by different causes such as trauma, severe bone infection and other factors are common in clinic and difficult to treat. Usually, bone substitutes are required for repair. Current bone grafting materials used clinically include autologous bones, allogeneic bones, xenografts, and synthetic materials, etc. Other than autologous bones, the major hurdles of rest bone grafts have various degrees of poor biological activity and lack of active ingredients to provide osteogenic impetus. Bone marrow contains various components such as stem cells and bioactive factors, which are contributive to osteogenesis. In response, the technique of bone marrow enrichment, based on the efficient utilization of components within bone marrow, has been risen, aiming to extract osteogenic cells and factors from bone marrow of patients and incorporate them into 3D scaffolds for fabricating bone grafts with high osteoinductivity. However, the scientific guidance and application specification are lacked with regard to the clinical scope, approach, safety and effectiveness. In this context, under the organization of Chinese Orthopedic Association, the Expert consensus for the clinical application of autologous bone marrow enrichment technique for bone repair ( version 2023) is formulated based on the evidence-based medicine. The consensus covers the topics of the characteristics, range of application, safety and application notes of the technique of autologous bone marrow enrichment and proposes corresponding recommendations, hoping to provide better guidance for clinical practice of the technique.

Objective: To study the expression of Wnt2b protein and the epithelial-mesenchymal transition related markers in tissues of carcinoma of bile duct and normal bile duct to determine the clinical significance. The relationships between the expression levels and clinicopathological characteristics were analyzed, and the correlation between Wnt2b and epithelial interstitial transformation (EMT), tumor invasion and metastasis were studied. Methods: A total of 60 patients with cholangiocarcinoma and 30 patients with normal bile duct tissues admitted to the Affiliated Hospital of Qingdao University from December 2008 to December 2013 were studied. The expressions of Wnt2b, E-cadherin and Vimentin protein were detected by SP immunohistochemical staining. The patients were classified according to the expressions of these proteins. Analyses were conducted on the relationships of these proteins with clinical characteristics of the patients with cholangiocarcinoma. Results: The positive expression rate of Wnt2b protein in carcinoma of bile duct tissues was 90.0%, which was significantly higher than that in normal bile duct tissues (χ²=38.1, P<0.05). The positive expression rate of Wnt2b in T₃ + T₄ was significantly higher than that in T₁ + T₂ (P<0.05). There were no correlations of the expression with patients’ age, gender, tumor location and degree of tumor differentiation (P>0.05). Patients with lymph node metastasis had a significantly higher positive expression of Vimentin than patients with no lymph node metastasis, and the loss of E-cadherin expression was increased (all P<0.05). There were no relationship of the expressions of these proteins with patients’ age, gender, tumor location and degree of tumor differentiation (P>0.05). The increased expression of Wnt2b in bile duct cancer cells was related to increase in EMT marker of the positive expression of vimentin and the loss of E-cadherin expression (both P<0.05). Conclusions Wnt2b protein overexpression in cholangiocarcinoma correlated with epithelial-mesenchymal transition related markers. The Wnt2b protein was correlated with cholangiocarcinoma occurrence, development, invasion and metastasis. Wnt2b has the potential to develop into a new therapeutic target for carcinoma of bile duct.

MicroRNAs (miRNAs) are a type of small non-coding RNAs that are often play important roles in carcinogenesis, but the carcinogenic mechanism of miRNAs is still unclear. This study will investigate the function and the mechanism of miR-638 in carcinoma (GC). The expression of miR-638 in GC and the DNA copy number of miR-638 were detected by real-time PCR. The effect of miR-638 on cell proliferation was measured by counting kit-8 assay. Different assays, including bioinformatics algorithms (TargetScan and miRanda), luciferase report assay and Western blotting, were used to identify the target gene of miR-638 in GC. The expression of miR-638 target gene in clinical CRC tissues was also validated by immunohistochemical assay. From this research, we found that miR-638 was downregulated in GC tissues compared with corresponding noncancerous tissues (NCTs), and the DNA copy number of miR-638 was lower in GC than NCTs, which may induce the corresponding downregulation of miR-638 in GC. Ectopic expression of miR-638 inhibited GC cell growth in vitro. Subsequently, we identified that PLD1 is the target gene of miR-638 in GC, and silencing PLD1 expression phenocopied the inhibitory effect of miR-638 on GC cell proliferation. Furthermore, we observed that PLD1 was overexpressed in GC tissues, and high expression of PLD1 in GC predicted poor overall survival. In summary, we revealed that miR-638 functions as a tumor suppressor in GC through inhibiting PLD1.
