This article summarizes and analysis the rules of acupoint selection in the treatment of dysmenorrhea.Method:Computer retrieval and manual search were combined to look for domestic literature on dysmenorrhea treated by acupuncture and moxibustion in year 2003 to 2011.There were altogether 20 qualified articles,concerning 28 acupoints.The above results showed that in the treatment of dysmenorrhea,the commonly used points are distributed in Ren,spleen meridian of foot-Taiyin,foot Yangming meridian and foot Taiyang meridian.Specific acupoints was the main type for selecting points.

Coordinated care delivery is faced with various challenges to carry out in China,which are major decisions to make for decision makers,including how to push forward,how to deliver resources, services and patients to primary institutions,and how to ease the difficulties and affordability of seeing doctors.Based on analysis of roadblocks in coordinated care delivery in China,the authors provided near-term and long-term policy recommendations on the system,including how to build a scientific and reasonable healthcare delivery system,coordinated care delivery by stages,building incentives and constraint mechanisms,and enhancing public awareness and patient-doctor education.

Concept of coordinated care delivery is clearly defined,before a comparative analysis is made between such a concept and the integrated care delivery concept which is popular overseas and similar.On such basis,a theory framework is established for building and implementing such care delivery in line with the integrated theory of care delivery systems.Coordinated care delivery system now in place in China aims at rationally delivering medical resources,services and patients to primary institutions,by means of efficiently distributing resources and service systems and integrating care delivery flows,thus offering patients with cost effective and appropriate services and optimizing the care delivery system.

Objective: To explore the effect of resveratrol on the chemosensitivity of cervical cancer cells and its regulatory mechanism. Methods: Hela/DDP cells were divided into four groups: Hela/DDP group, resveratrol group, CDDP group, and resveratrol+CDDP group. Cell viability and proliferation were detected by CCK-8. Cell cycle and apoptosis were tested by flow cytometry. The expressions of p21, CDK2, cyclinD1, caspase-9, caspase-3, Bcl 2 and Bax were measured by Western blot. Results: The sensitivity of Hela/DDP cells to cisplatin was lower than that of Hela cells (P<0.01). Resveratrol significantly enhanced Hela/DDP cells' sensitivity to cisplatin (P<0.01). The inhibition of CDDP on the proliferation of Hela/DDP cells was increased by resveratrol (P<0.01). The G1 phase arrest of CDDP on Hela/DDP cells was enhanced by resveratrol (P<0.01). The expression of p21 was higher in resveratrol group and CDDP group than in Hela/DDP group, and the expressions of CDK2 and CyclinD1 were lower than in Hela/DDP group (P<0.01). Compared with CDDP group, the expression of p21 in resveratrol+CDDP group was elevated with the decrease in CDK2 and cyclinD1 expressions (P<0.01). The induction of CDDP on the apoptosis of Hela/DDP cells was elevated by resveratrol (P<0.01). The expressions of caspase-3, caspase-9 and Bax were higher in resveratrol group and CDDP group than in Hela/DDP group, and the expression of Bcl-2 was lower than in Hela/DDP group (P<0.01). Compared with CDDP group, apoptosis in resveratrol+CDDP group was increased with the reduced expression of Bcl-2 (P<0.01). Conclusion: Resveratrol enhances the chemosensitivity of cervical cancer cells by inducing cell cycle arrest and apoptosis.

BACKGROUND:Anterior cruciate ligament is the important anatomic structure to maintain the knee joint stability. The tendon bone healing and clinical functional recovery after anterior cruciate ligament have attracted more attention. OBJECTIVE:To observe the healing of graft tendon and surrounding bone with histological method through the same diameter grafts matching with the bone tunnel of different sizes in the anterior cruciate ligament reconstruction surgery, and to detect the functional recovery with biomechanics. METHODS:Middle 1/3 of canine autologous tendon was selected as the anterior cruciate ligament graft, and then trimmed into the same diameter of 4 mm. Sixteen adult mongrel canine were randomly divided into four groups. The anterior cruciate ligament was resected completely, and the tibial and femoral tunnels were prepared on the end sites of tibia and femur with the diameters of 5, 4.5, 4 and 3.5 mm, then implanted into the tendon in prepared and linked into the bone tunnel. At 6 weeks after reconstruction, the experimental canine were sacrificed under general anesthesia to col ect the tissue and organs in the surgical area. Then the hematoxylin-eosin staining, biomechanical testing and statistical analysis were performed. RESULTS AND CONCLUSION:At 6 weeks after anterior cruciate ligament reconstruction, anatomical observation showed that there were no significant differences in growth of grafts and bone tunnels between groups;hematoxylin-eosin staining showed sharpey-like fibronectin could be seen in the tendon bone healing surface, and the col agen fibers in the 3.5 mm bone tunnel group were more compact and regular than those in the other groups;the biomechanical testing results in the 3.5 mm bone tunnel group were better than those in the other groups. The results indicate that during anterior cruciate ligament reconstruction, decreasing the diameter of bone tunnel that matched with grafts in order to make the tendon and the bone tunnel closely matched can provide a more stable cel biological and mechanical environment, accelerate the formation and transformation of tendon-bone healing interface, and can improve the quality of tendon-bone healing.

BACKGROUND:There are numerous studies about mechanical changes of recast cobalt-chromium ceramic al oys. However, little is reported on the mechanical properties of cobalt-chromium ceramic al oys containing once-used al oys after recasts.
OBJECTIVE:To study the effects of different proportion of once-used al oys to recasting cobalt-chromium al oys on their mechanical properties, including tensile strength, yield strength, elongation and hardness.
METHODS:Cobalt-chromium al oys cast samples were prepared and recast for three times (40%once-used al oys were added per time). The tensile strength, 0.2%yield strength, percentage of elongation, flexural strength and Vickers hardness of each specimen were measured. In addition, microscopic metal ographic observation was done.
RESULTS AND CONCLUSION:Being recast for three times, cobalt-chromiun al oys showed no significant differences on their tensile strength, 0.2%yield strength, percentage of elongation, flexural strength and Vickers hardness. GenerationⅠal oy samples had uniform size, smal diameter and smal carbide size distributing along the grain boundary, mainly exhibiting spherical and irregular wormlike forms. Generations Ⅱ and Ⅲ samples were uniform in shape, but crystal grains were coarsened a little. Carbide from Generation IV samples began to be coarsened, irregular wormlike carbides were increased in amount, and a few of non-metal ic inclusions could be found in grains. Cobalt-chromium al oys can be recast after addition of 40%once-used al oys for three times at least in air environment, without decrease of the mechanical properties.
