Given the significant improvement in terms of its coverage and compensation depth,China's basic medical insurance system has inherent setbacks in its structure as held by the authors.They hold that the medical insurance as the most important source of compensation for medical institutions,should further reform its structure of financing and reasonably raise the percentage of compensation; adjust the time reference and space reference for prepayment estimation such as the total prepaid amount; deepen supportive reforms for the payment manner.All these measures aim at minimizing impact of the payment control mechanism on routine medical activities and exploring diversified payment manners that are feasible.

Objective To explore the impacts of different nutrition support methods on short-term outcome in critically ill adult patients. Methods We retrospectively reviewed the clinical data of 1503 critically ill adult patients who needed nutrition support in an mixed intensive care unit (ICU) of a tertiary care university hospital from January 1994 to December 2009. The complication of nutrition support, length of stay (LOS) in ICU, morbidity of infection and multiple organ dysfunction syndrome (MODS), and mortality among different nutrition support methods were compared. Results The Nutritional Risk Screening (NRS) scores of the enrolled patients were no less than 3. LOS in early enteral nutrition (EN) patients were significantly shorter than those in not-early EN patients (P < 0. 001) and parenteral nutrition (PN) patients (both P < 0. 001). Infection rate (P < 0. 001),morbidity of MODS (P < 0. 001) and mortality (P < 0. 001) were significantly lower than those in not-early EN and PN patients. LOS of patients receiving PN rich in glutamine (Gln) was significantly shorter than that in conventional formula (P = 0. 0000). Morbidity of infection (P= 0. 0252) and MODS (P = 0. 0030), mortality (P =0. 0305) were significantly lower than that of conventional patients. LOS of patients receiving intensive insulin therapy (IIT) was significantly shorter than that of controlled group (P = 0. 0000). Morbidity of infection (P =0. 0001) and MODS (P = 0. 0237) and mortality (P =0. 0427) were significandy lower than those of controlled group. Conclusions Nutritional risk is prevalent among critically ill adult patients. Early EN, PN of rich in Gln,and receiving IIT can shorten LOS, decrease morbidity of infection and MODS, and improve prognosis among these patients.

Objective To prepare lipid-coated ultrasound microbubbles containing 10-HCPT(HLM) and explore the antitumor effects on mice xenografed H22 solid tumor using the technique of ultrasound-mediated HLM destruction. Methods Sixty-four tumor-bearing mice were radomly divided into A and B groups. Each group was divided into four groups again and administered respectively by tail vein with HI.M, non-drug-loaded microbubbles,10-HCPT and saline once a day. Ultrasound irradiation was applied on the tumor sites immediately after injection. After 7 days of consecutive treatment, all mice in group A were sacrificed and the tumors were harvested to measure weights. The tumor inhibition rate was calculated by weights. The tumor microvessel density (MVD) was detected by immunohistochemical staining. The tumor growth curve was depicted according to volumes. The survival time of mice in group B was recorded. Results The tumor inhibition rate was the highest in HLM group while this group's MVD was the lowest. Survival time in HLM group and 10-HCPT group were obviously longer compared with the control group,while no statistic difference was observed between the two groups. There was no statistic difference between the group of non-drug-loaded microbubbles and the control group. Conclusions Ultrasound irradiation mediates HLM destruction so that the drug is released from the vihicles at the same time, which can significantly enhance the tumor inhibition effect of 10-HCPT on the H22 tumor. This technique is expected to be adopted as a novel tool for liver cancer chemotherapy.

We established a rapid detection method of New Delhi Metallo-beta-Lactamase Gene (NDM-1) based on Loop-mediated Isothermal Amplification (LAMP). With the application of LAMP, we designed four sets of LAMP premiers, using NDM-1 gene as the target sequence, and selected the set of optimal primers. Meanwhile, we established optimal reaction systems and conditions to carry out the sensitivity and specificity experiments. The experiment results showed that the whole detection process took only one hour and could be observed visually. In the experiment of sensitivity, NDM-1 gene had a detection limit of 6 copies in each reaction. In the experiment of specificity, we detected NDM-1 gene in 4 pathogen strains (Klebsiella pneumoniae, Escherichia coli, Staphylococcus aureus, Streptococcus pneumoniae), and the total DNA from intestinal microbes and the total DNA from soil microbes. We had not detected the amplification reactions. The detection method established could rapidly detect NDM-1 gene and visualize the experiment result. The method is easy to operate and has high sensitivity and specificity and thus has great application value in basic research laboratories, emergent detection and spot detection.

From the perspective of the government′s positioning of public hospitals, the basic problems of functional positioning of public hospitals are clarified. According to different positioning subjects, the positioning of public hospitals is divided into three categories: government positioning, social positioning and self-positioning. By analyzing the connotation of the positioning mechanism of public hospitals, the outstanding performance of the insufficient realization of the government′s positioning of public hospitals, and the influencing factors of the government′s positioning of public hospitals, this paper tries to provide a theoretical basis for formulating a scientific and comprehensive reform plan of public hospitals.

Objective To investigate the effects of camel milk on immune cells in lamina propria (LP) of intestinal mucosa in mice. Methods Six male C57BL/6 mice(6-8 weeks) were randomly divided into two groups as follows: camel milk treatment group and double distilled water (DDW) control group. Samples of cells in LP of intestinal mucosa were collected. Cell counts and percentages of immune cells in LP were analyzed by flow cytometry. Levels of IL-4,IL-10,IL-17 and IFN-γ in the supernatants of cell cul-ture were measured by ELISA. Results Compared with the DDW control group, the camel milk treatment group showed increased percentage and absolute number of CD4+T cells as well as IFN-γ-secreting CD4+T cells in LP of intestinal mucosa(P<0.05). Moreover,significantly enhanced expression of IFN-γ and sup-pressed secretion of IL-4 were found in the camel milk treatment group (P<0.05). Conclusion Camel milk can promote the proliferation of CD4+T cells and enhance the secretion of IFN-γ,indicating that camel milk regulates the proliferation and cytokine secretion of immune cells in LP of intestinal mucosa in healthy mice.
