Objective To evaluate the efleet of continuous subcutaneous insulin infusion (CSII)combined with mefformin hydroehloride( Met H)on type 2 diabetic patients. Methods 240 patients with type 2 diabetes melli-tus (T2DM) were divided into 3 groups randomly: CSII combined with Met H ( A group: n=80) ; simple CSII ( B group:n=80) ; multiple deliver insulin (MDI) ( C group: n=80). The levels of blood glucose, HbA1 e, therapeutic time, a-mount of insulin, Fins ,C-P, HOMA-IR and IAI were compared among them before and after 10d of treatment. Results GroupA, B eornpared with group C, the levels of HbA1 e significantly deeroased in other two groups [ ( 8.0±3.2)%vs. (6.9±1.4)% and(7.0±1.2)% ] (aU P<0.05),so did the therapeutic time[(6.0±1.9)d vs. (3.0±1.4) and(3.5±1.5) d] and insulin dose[ (55.0±17.0) U/d vs. (38.0±15.0) U/d and(45.0±16) U/d] (all P<0.05). The insulin dose was much less in group A than in group B. Versus group B and C,the HOMA-IR of group A (0.8±0.3 vs. 1.5±0.4 and 1.6±0.4)decreased(P<0.05) ,and IAI(-2.0±4.3 vs. -3.6±4. 2 and -4.1±4.3) increased (all P<0.05), without the function impairments of heart, liver or kidney. Conclusion CSII in combi-nation with mefformin hydreehloride can significantly enhance the treatment effect of the patients with type 2 diabetes mellitns; reduce blood glucose and HbA1 e, improve insulin resistenee,lessen insulin need.

Cartilage injury has a very limited capacity of recovery by itself due to the lack of blood vessel in cartilage tissues. Current studies indicate that many kinds of cytokines have the function of promoting cartilage formation or repairing the injured cartilage with cartilage-like tissues. Cell-mediated transfer of the respective genes may ideally combine the supply of a chondrogenic cell population with the production of certain factors se-creted from the lesion and to promote the repairing of the lesion, which is considered the best treatment. Gene therapy based on this technology has developed rapidly in recent years. This review aims to summarize some of the development of the research in the field.

ObjectiveTo study the hemodynamic changes in combined portoazygous devascularization and mesocaval shunt for treating portal hypertension and the effect of this operation. Methods100 cases of portal hypertension who received this combined operation from 1980 to 1995 were analyzed retrospectively. ResultsFree portal pressure(FPP)after shunt decreased to 1.92 kPa,which decreased portal pressure and preserved with (2.46 ± 0.30)kPa to maintain a good inflow to the liver and the encephalopathy rate was lowered. There was no death, and the effect was satisfactory. 5～15 years follow-up of 89 cases showed no rebleeding,with only 5% of encephalopathy and 15% of total mortality. Among them, 13 cases of Child C died of late-stage hepatopathy, such as liver failure, liver cancer and hepatorenal syndrome,with 94.5% of 5-year survival rate and 68.5% of 10-year survival rate. ConclusionThis combined operation is characterized by complete devascularization of sustaining varices and distal partial shunt with logical diameter. A perfect combination of both shunt and devascularization, it's one of the best choices currently available for treating portal hypertension in China.

Objective The article introduces the present status of the application of comparative proteomics in study of tumor marker. Methods This essay review the present status and advances of the application of comparative proteomics in study of tumor marker through refer considerable literatures about proteome, proteomics and tumor marker. Results Follow the study of human genome deepening; the paradox between the finiteness of genes’ number and stability of genes’ structure and the variety of the life phenomena is more conspicuous. Then, the study of proteomics was pushed to the advancing front of life science research. The application of comparative proteomics to tumor research becomes a hot spot nowadays. Conclusion Screening tumor marker via comparative proteomics is an extremely promising research.

Aim To study preparation of lutein from the extraction Marigold flowers by biotransformation.Methods Screen bacterium for lutein esters biotransforming by studying on the biotransformation of lutein esters by Penicillium on tabulate revulsive culture medium.Porule of and Aspergillus niger Penicillium could transform lutein esters into lutein,but biotransformation of Penicillium was better than Aspergillus niger.Porule of Pleurotus ostreatus could not grow on revulsive culture medium,but Pleurotus ostreatus could grow on the culture medium and transformed lutein esters into lutein.Research of shaking flash fermentation of Penicillium for trans-forming lutein esters.When pH is 6.0,quantity of incubation is 2 bacteria plugs and fermentation time is 12～24 hours,the transformation is completed and the content of lutein is 91.6%(HPLC)。Result Prolonging the transformation time will improve the percent of lutein but the content of lutein decreased.Conclusion Biological transrormation can be used from calendula officinacis extract preparation.

IL-17,as a pro-inflammatory cytokine,is one of the early initiation factors of the inflammato-ry response induced by T cells.It can induce and regulate multiple immune responses.Recent studies have re-vealed that myeloid neutrophils,macrophage,mast cell and other innate immune cells all can secrete large a-mount of early responding IL-17 in organs suffering ischemia/hypoxia,and in turn can activate,amplify and re-cruit neutrophils to the reperfusion-damaged tissue to release large amount of free radicals and lysozyme that cause IRI.Researchers have also provided evidence that appropriate administration of anti-IL-17 mono-antibody to neutralize IL-17 during early reperfusion stage would reduce the tissue damage.The purpose of this review is to summarize the research progress of the effects of IL-17 produced by innate immunocyte on organ reperfusion injury.

Objective:To study the radiation dose rate around patients underwent renal dynamic imaging of SPECT with 99Tcm-DTPA, so as to provide the basis for ensuring the radiation safety of the surrounding environment and the general public.Methods: 109 patients who underwent renal dynamic imaging were enrolled in this study, and the radiation dose rates of different time and different distance after 99Tcm-DTPA was injected patients were measured. And then, the changes of dose rate following time and distance were analyzed. Results: At the 0.5h, 1h, 2h, 3h, 6h, and 7h after radiopharmaceuticals were injected patients underwent renal dynamic imaging, the radiation dose rates were 0.76-8.86 μSv/h, 0.68-7.27 μSv/h, 0.57-4.52 μSv/h, 0.56-3.90 μSv/h, 0.23-2.07 μSv/h and 0.21-1.05 μSv/h, respectively, between 0.5 m and 4 m away from patients. At 24h after radiopharmaceuticals were injected, all of radiation dose rates at different distances around patients were same with background values.Conclusion: The radiation dose rates around patients underwent renal dynamic imaging will rapidly decrease with the increasing of time and distance. At 24h after radiopharmaceuticals were injected, all of radiation dose rates at different distances away from patients were same with background values.

Objective To investigate infection statue and antibiotic susceptibility of Mycoplasma urealyticum and Mycoplasma hominis in the genitourinary tract in our area, so as to instruct the rational use of antibiotics. Methods Genitourinary secretions were collected with swabs. They were cultured with the diagnostic kit of Mycoplasma (Biomerieux Company) to detect M. urealyticum and M. hominis. Meanwhile the susceptibility of Mycoplasma against 9 antimicrobial agents was tested with the same kit. According to the manual of the kit,the results were read. The data were statistically analyzed. Results A total of 2 410 samples were collected, and the positive rate was 58. 1%. Among 1410 positive cases of Mycoplasma, 901 cases were M. urealyticum (37.4%), 85 were M. hominis (3.5%), and 415 were M. urealyticum combined with M. hominis (17.2%).The susceptibility rate of M. urealyticum to josamycin, pristinamycin, ciprofloxacin was 98. 8%, 98. 8% and 6. 4% respectively, while the susceptibility rate of M. urealyticum combined with M. horninis was 86.9%,86. 8% and 2.6% respectively. Conclusion M. urealyticum is the major cause of Mycoplasma infection in genitourinary system. Josamycin and pfistinamycin are more effective than other antimicrobial agents to treat Mycoplasma irffection. Ciprofloxacin is more resistant than other antimicrobial agents. Sensitive antibiotics should be selected based on the results of bacterial culture and drug sensitivity tests so as to raise the clinical curative effects.
