The accessibility of drugs is the fundamental condition for achieving the universal health care, and price is the important factor of accessibility.It is essential to have a national price negotiations mechanism for the patented drugs and for exclusive production of drugs.As for the regular works, the national price negotiations mechanism should be ruled by law, while rules and regulations should be formulated accordingly.This paper discusses the specific content and the clarification of the legislative principle of legal framework for the negotiations, main roles, and selection of objects, procedure, results and application of the negotiations.It also analyses the existing problems are analyzed, and put forward the future legislation and corresponding rules.

In critically ill patients,evoked potential(EP) testing is an important tool for measuring neurologic function,signal transmission,and secondary processing of sensory information in real time.EP potential measures conduction along the peripheral and central sensory pathways with longer-latency potentials representing more complex thalamocortical and intracortical processing.In critically ill patients with limited neurologic exams,EP provides a window into brain function and the potential for recovery of consciousness.Brainstem auditory EP and cortical event-related potentials are most commonly used in ICU.The primary indications for EP in critically ill patients are prognostication in anoxic-ischemic or traumatic coma,monitoring for neurologic improvement or decline,and confirmation of brain death.Historically,EP has been regarded as a negative prognostic test,that is,the absence of cortical potentials are associated with poor outcomes while the presence cortical potentials are prognostically indeterminate.In recent studies,the presence of middle-latency and long-latency potentials as well as the amplitude of cortical potentials is more specific for good outcomes.Event-related potentials,particularly mismatch negativity of complex auditory patterns,is emerging as an important positive prognostic test in patients under comatose.In infants,other than anoxic-ischemic or traumatic brain injury,brainstem auditory is also widely used in premature baby,bilirubin encephalopathy and detection of possible hearing loss.

To evaluate the value of detection of DNA aneuploidy in exfoliated airway epithelia cells of sputum specimens by the automated image cytometry for the identification of lung cancer, 100 patients were divided into patient group (50 patients with lung cancer) and control group (30 patients with tuberculosis and 20 healthy people). Sputum was obtained for the quantitative analysis of DNA content of exfoliated airway epithelial cells with the automated image cytometry, together with the examinations of brush cytology and conventional sputum cytology. Our results showed that DNA aneuploidy (DI>2.5 or 5c) was found in 20 out of 50 sputum samples of lung cancer, 1 out of 30 sputum samples from tuberculosis patients, and none of 20 sputum samples from healthy people. The positive rates of conventional sputum cytology and brush cytology were 16% and 32%, which was lower than that of DNA aneuploidy detection by the automated image cytometry (P<0.01, P>0.05). Our study showed-that automated image cytometry, which uses DNA aneuploidy as a marker for tumor, can detect the malignant cells in sputum samples of lung cancer and it is a sensitive and specific method serving as a complement for the diagnosis of lung cancer.

Traditional Chinese medicine emphasizes the overall state of health, pays attention to individual health condition, highlights maintaining health rather than diseases, shows the clinical effectiveness with flexible treatment. It is the unique resource of health service in our country. Currently, the qualification and certification of traditional Chinese medicinewere only applied in medical practitioners of traditional Chinese medicine and Gua sha.This led to the status quo of vacuum to the traditional Chinese medicine in the fields of access system and standardization. Thus, it is urgent to unify and standardize the access and qualification traditional Chinese medicine, in order to TCM inheritance and development. The establishment of the system should be based on clinical effect and difference among the clinical application. The system can be divided into easy, middle and senior level TCM therapist. TCM therapist with different levels can apply the qualification and certification based on their own levels.

Objective To explore the cause and epidemiologic characteristics of Keshan disease.Methods The cases observation method,epidemiologic methods,fungus-mycotoxin methods and the analytic chemistry methods were used in our studies.Results From the year 1973-1975,in serious endemic areas,fifteen families and one disease outbreak village were investigated,it was found that all patients and his family members had eaten a vast amount of mould millet or maize 4-12 months before onset of the disease; the millet samples collected from endemic areas were cultured and they werc found to be polluted mainly by fungus(20％ of all),the toxin was citreoviridin(CIT).The cause factor of Keshan disease entered into human body through grain but not drinking water,and the transmitting effect was not different with different grains,millet and maize transmit but wheat did not;according to data of endemic disease inspection,after 1990 no new cases of Keshan disease had been reported in the country,at the same time the CIT content in grain produced in endemic areas did not reduced so quickly.However,after 1983,the reform of agriculture promoted significantly the hygienic quality of grain which was considered to be a specific cause for the decreasing of Keshan disease threatening; Keshan disease was distributed on the narrow-long areas from Yunnan till Heilongjiang.These areas were the connection parts,between the cold west north high lands and the warm-moist east-south flatlands,a narrow-long region.The year mean temperature and humidity in endemic areas might be suitable for growing of fungus and production of its toxin ; of animal experiment,rats were feed with CIT contaminated grain every day 4 mg/kg(body weight) for 4-6 weeks,the necrosis of myocardium and cell mitochondria swelling,proliferation and damage were found,just like what had been seen in died cases of Keshan disease.Conclusions The cause of Keshan disease is CIT toxin,the endemic conditions are geographic climate suitable for growing of fungus and production of its toxin and bad hygienic situation of grain storage.Some discussion about the prevention mcthod was proceeding.
