The advent of nanoscience and nanotechnology offers unprecedented opportunities in nanomedicine, such as increas-ing therapeutic efficiency and decreasing undesired side effects in cancer treatment. Photodynamic therapy (PDT) is a non-invasive pho-totherapy-based method that is applied in the treatment of cancer and other diseases and has important clinical value. PDT can be com-bined with other therapies to realize the synergistic treatment. The emergence of up-conversion nanomaterials provides a fundamental method to solve the problem of photodynamic therapy of deep tumors. Moreover, the versatile preparation and surface modification methods facilitate the fine-tuning of the emission spectrum of up-conversion nanomaterials and the improvement of the photosensitiz-er's loading capacity. This study reviews the development in design and application of up-conversion nanomaterials for PDT of cancer.

Objective The clinical significance of serum cytokine in kidney transplanted patients have been evaluated by observing the variation of cytokines and biochemical parameters. Methods The serum IL-1?、IL-1?、IL-2、IL-4、IL-6、IL-8、IL-10、VEGF、IFN-?、TNF-?、MCP-1、EGF and 22 items of biochemistry parameters have been followed in 10 patients during 90 days around operation time. Cytokine had been measured by biochips methods in evidence 180 automatic biochips analyzer. The serum biochemical parameters had been measured by Roche diagnostic company reagents kits in HITACHI 7600DDP analyzer.Results Serum IL-6 and IL-8 had reached the highest level [(42.5?42.8) ng/L and (343.5?493.1) ng/L] at 7 days after kidney transplantation,whereas IL-2 and IL-10 were reached the highest level [(16.3 ? 5.7) ng/L and (16.6 ? 24.2) ng/L] respectively at 14 days. Then they decreased gradually, but IL-6 and IL-8 were still higher than normal control. The decreased VEGF, EGF and MCP-1 in kidney failure patient had increased gradually after transplantation. But EGF was still lower than normal control at 90 days after operation. Urea、Cr、Ua and Glu had been restored to normal level after two month of operation and the significant relationship between IL-8 and serum LDH activity have been found( r=0.93,P

Objective The study was to provide evidence for the development of local community health services through the analysis of patiems' expectations for community health services. Methods The expectations were indirectly evaluated by investigating the patients in the willingness-to-pay. Results The patients had a generally high expectation for health community services and they would be highly disappointed once their expectations fall short. Conclusions Those expectations that could be realized with short-term efforts ought to attract high attention of community health service providers and made important goals to achieve in the near future.

OBJECTIVE: To observe whether injection of medicine into low hydraulic resistance point along meridian brings about higher medicinal effect and to explore the efficacy of the theory that meridians are made up of channels featuring low hydraulic resistance by observing the diuretic effect of injecting furosemide or saline into the low hydraulic resistance point Shuifen (CV 9), vein and Zusanli (St 36) respectively. METHODS: Acute edema was induced in pigs by rapid intravenous injection of 2 000 ml normal saline. The pigs were divided into four groups: Shuifen (CV 9) injection of half dose furosemide group (SFF group), intravenous injection of full dose furosemide group (VF group), Zusanli (St 36) injection of full dose furosemide group (ZSLF group), and Shuifen (CV 9) injection of half dose normal saline group (SFS group). The accumulated urine quantity and the urine quantity generated in every 15-minute period were measured in each group respectively, every 15 minutes after injection, and the measurement lasted for two hours at one experiment. Each group involved eight times of experiments with one pig used for one experiment, which means the whole observation involved 32 times of experiments. RESULTS: The accumulated urine quantities observed in both SFF group and VF group were higher than those in the ZSLF group and the SFS group all through the measurement, showing significant differences during the period from the 15th minute to the 45th minute (P<0.05). But no significant difference was observed between the SFF group and the VF group during the whole 2-hour measurement (P>0.05). Analysis of urine quantity generated in every 15-minute period showed that diuretic effect climaxed during the 15th minute to the 30th minute in both SFF group and VF group. By contrast, ZSLF group reached diuresis climax during the 45th minute to 60th minute and no diuresis climax was observed in the SFS group all through the measurement. CONCLUSION: Injection of medicine into low hydraulic resistance point along meridian generates faster and more powerful medicinal potency, and this is likely to be applied to clinical practice. The theory that meridians are channels featuring low hydraulic resistance is important to the elucidation of meridians.
