At present, there are the pheuomena of asking sor maney fram patients, writing out unnecessary prescription,and getting medicaine without payment among physicians. It is mot accord with the humanitarianism for patients imim China As everyone knows, the medical moraiith of health adimin'strative cadre involve that whether of not the quality of health services correspond to need of patients so, in this paper, the author discusses that how to strengthen the medical morality for health adimin's trative cadres.

Objective: To prepare injectable interferon α-2b(IFN-α-2b) loaded microsphere and develop a long-acting dosage form. Methods: IFN-α-2b loaded microspheres were prepared with poly(lactic-co-glycolic acid) (PLGA) as carrier material by double emulsion(w/o/w) method and solid in oil in oil(s/o/o) method separately. Physical and chemical characteristics of microspheres (mean diameter, morphology and drug entrapment efficiency) were evaluated; the in vitro release behavior and influencing factors of the microspheres were determined by micro-BCA(bicinchoninic acid) method; and IFN-α-2b stability during encapsulation and in vitro release was evaluated by sodium dodecyl sulfate polyacrylamide gel electropheresis. Results: The 2 types of microspheres produced had good shape and dispersive quality and a drug entrapment efficiency of more than 80%. IFN-α-2b bulk ultrafitration can significantly influence the mean diameter and in vitro release behavior of microspheres prepared by w/o/w method. The accumulated release(within 1 month) of the microspheres prepared by both methods was significantly improved when using PLGA with lower inherent viscosity. SDS-PAGE test showed aggregation of IFN-α-2b with s/o/o method, while there was no difference between the electrophoretic behavior of bulk IFN-α-2b and IFN-α-2b in microspheres prepared by w/o/w method. Conclusion: IFN-α-2b can be encapsulated into injectable microspheres to yield a one-month continuous release by both w/o/w method and s/o/o method.

Objective To investigate the clinical effect of Sodium Hyaluronate Injection and psychological intervention in the treatment of knee osteoarthritis. Methods The control group of patients with knee osteoarthritis treated treatment group in the conventional research on Sodium Hyaluronate Injection, Sodium Hyaluronate Injection treatment combined with psychological intervention, record the two groups before and after treatment of knee joint function changes. Results There was no significant difference between the two groups in the knee function before treatment. After the corresponding treatment, the Lysholm scores of the two groups were significantly higher than before, and the knee joint function improvement in the study group was better (P<0.05). Conclusion The application of sodium hyaluronate and psychological intervention in the treatment of osteoarthritis of knee joint can significantly improve the efficacy of patients, and is conducive to the protection of their physical and mental health, quality of life.

AIM: To establish a method of determining the content of total saponin of Radix et Rhizoma Notoginseng in buccal tablets by HPLC. METHODS: Chromatographic conditions are as follows:Hypersil NH_2 column(4.6 mm?200 mm,5 ?m) as the stationary phase,acetonitrile-1% phosphate buffer solution(0-10 min,20:80;10-20 min,25:75;20-25 min,45:55;25-30 min,50:50) as the mobile phase,the velocity of flow is 1.0 mL/min,the temperature of coloum is 35(?C) and the detection wavelength is 203 nm. RESULTS: The HPLC method has good linearity in determining the total saponin of Radix et Rhizoma Notoginseng content,and we can detect four saponins at the same time,linear range,ginsenoside Rg1 0.093 75-6 ?g,ginsenoside Re 0.011 72-0.75 ?g,notoginsenoside R1 0.023 44-1.5 ?g and ginsenoside Rb1 0.140 6-9 ?g,the correlation coefficient r=0.999 9. CONCLUSION: The established method in this article is simple and convenient,with good reproductivity.We can detect four saponins in the total saponin of Radix et Rhizoma Notoginseng Buccal Tablets at the same time by this method.It can be used for quality control of the total saponin of Radix et Rhizoma Notoginseng Buccal Tablets.

Interventional diagnostic and therapeutic techniques have developed rapidly in recent years with more and more practically and widely utilization as time goes by. The diagnostic procedures consist of percutaneous biopsy, CT discography, pressure measurement of intervertebral disc; and the therapeutic measures include percutaneous periradicular and joint therapy, decompression of sacral cyst, vertebroplasty, kyphoplasty, decompression of intervertebral disc, transarterial chemotherapy and embolization in spinal tumor, and newly developed percutaneous posterior lumbar intervertebral fusion. All above mentioned interventional techniques for spinal column diseases are developing day by day with a promising future and will play an important role in the field of interventional radiologist research.

To elucidate the academic thought of Professor ZHOU Zhong-ying about cancerous toxin. Professor Zhou holds that the cancerous toxin,a toxic pathogen occurring during the occurrence and development of malignant tumor,is the key for occurrence of malignant tumor. The compound pathogeneses of malignant tumor are the coexistence,reciprocal causation,combination and transformation between the cancerous toxin and the pathological factors of phlegm,blood stasis and dampness. Based on the theory of cancerous toxin,the therapeutic rules of malignant tumor should be removing carcinoma and eliminating toxin,supporting vital qi to eliminate pathogens,and combined the resolving phlegm,removing blood stasis,eliminating dampness or clearing away heat according to the different pathological factor accompanying,such as phlegm,blood stasis or dampness,etc.

OBJECTIVE To discuss effective methods of nosocomial infection management in disinfection supply division to control the nosocomial infection and improve quality of medical care.METHODS We established the overall arrangement of disinfection supply to strenthen the cleaning,packing and sterilization management for the recycled medical instruments,storage and distribution of the aseptic products,as well as the occupational exposure and protection among the staff in there,to establish the effective nosocomial infection management organization in whole hospital,particularly in disinfection supply division,to study technology of hospital infection,and to enhance the consciousness in control of nosocomial infection.RESULTS The medical safety was improved and nosocomial infection was controlled effectively.CONCLUSIONS The scientific management in disinfection supply division,is the main path way to control nosocomial infection.

Objective:To study the impact of clinical pharmacy information management system on antimicrobial stewardship in a general teaching hospital. Methods:The main function, deficiencies and aspects needing improvement of clinical pharmacy information management system, and its influence on antimicrobial stewardship were introduced. Results:The information system had such functions as antimicrobial usage statistics, evaluation of antimicrobial prescription, and the use intensity calculation of antimicrobials. By using the information system, manpower of antimicrobial stewardship was saved, antimicrobial statistics became more comprehensive and objective, and dynamic real-time monitoring of antimicrobial drugs management was realized. However, the system still had some shortcomings needing improvement. Conclusion:Clinical pharmacy information system can promote the implementation and efficiency of antimicrobial stewardship.

The chief cause of cancerous pain include six climate exopathogens,internal damage by excess of seven emotions,improper diet and deficiency of vital qi.Accumulation of cancerous toxin,intermingled phlegm and blood stasis and obstruction of meridians are the basic pathogenesis of cancerous pain,among which the accumulation of cancerous toxin is the key point of the pathogenesis,and phlegm and blood stasis are main pathological factors,the both are cause and effect for each other.The deficiency of vital qi is the internal factor of the disease.The location of disease concerns the relative viscera and meridians.The nature of disease is deficiency in the "root" and excess in the "branch" and excess in the "branch" is the main aspect.The therapeutic rules of the disease are removing toxic substance and removing stasis,resolving phlegm to dredge collaterals.And removing cancerous toxin is the crux of the therapy,and resolving phlegm to removing stasis should be applied from the beginning to the end.
