2.The Impact of Universal Coverage Policy on Catastrophic Health Payments in Thailand
Chinese Health Economics 2013;(10):95-97
Before 2002, the three existing basic medical security systems of Thailand covered 30% of the population, and the surplus population participated in the universal coverage(UC)policy of medical security system which promulgated in 2002. Since the implement of UC policy, it has improved the equity of medical service application and health financing, reduced Catastrophic Health Payments and low-income groups have obtained more benefits. The incidence rate of Catastrophic Health Payments decreased and the spending burden of catastrophic health expenditure in low-income groups decreased from 6.11%(2000)to 4.65%(2002).
3.Factors influencing health insurance patients hospitalization expenses for three disease entities
Chinese Journal of Hospital Administration 1998;0(11):-
Objective To identify the chief factors influencing health insurance patients' hospitali-zation expenses so as to provide basis for the control of irrational increase in medical expenses and reform in the mode of medical insurance payment. Methods All the medical insurance cases involving the three disease entities in two hospitals of a certain city for the past three years, which totaled 647, were collected and a statistical analysis was made of the possible influencing factors using multi-stepwise regression analysis. Results The factors influencing the health insurance patients' hospitalization expenses included choice of hospitals, length of stay, performance of operations, proportion of drug fees, and province- wide readjustment of medical service prices. Reducing length of stay and lowering proportion of drug fees were the key to controlling expenses. Conclusion It is imperative to formulate scientific diagnostic and treatment routines and expense standards for single disease entities, speed up and deepen reform in the medical insurance system, and, on the basis of trying out payment based on certain single disease entities, implement payment based on disease entities.
4.Analysis on the occurance rate of pneumothorax after percutaneous pneumocentesis
Journal of Interventional Radiology 2001;10(2):103-104
Objective To analyze the influence of multiple variable factors on the occurance rate of pneumothorax associated with transthoracic needle aspiration biopsy of the lung. Methods Fluoroscopically guided lung biopsies were performed in 46 patients. Variable factors were analyzed including lesion size, location, number of puncture, presence of emphysema and patients position after needle biopsy of the lung. Results Pneumothorax occurred at 9 (19.6%) of 46 patients and that occurred at 4 (44.4%) of 9 emphysematous patients. Among them 2 necessitated chest drainage tube placement. The pneumothorax occurance rate was 30% (3/10) for lesions of diameter 3cm or less in size. In the dependent group, pneumothorax occurred in 4 of 20 patients (20%). In the nondependent group, pneumothorax occurred in 5 of 26 patients (19.2%). Conclusion The correlation showed that increasing frequency of pneumothorax with decreasing size of lesions. An increased rate of pneumothorax was correlated with presence of emphysema. Patients with emphysema are more likely to have a symptomatic pneumothorax. No significant differences were found in the incidence of pneumothorax between patients placed with the puncture site dependent after biopsy and those placed with the puncture site nondependent.

Salteffectinhigh-voltageassistedlaserdesorptionionizationmassspectrometry(HALDI-MS)has been studied under both positive and negative ion modes using L-tyrosine, β-cyclodextrin, α-lipoic acid, as well as the complex formed between α-lipoic acid and β-cyclodextrin as the test analytes. Compared the mass spectra obtained with and without the addition of salt, it is found that HALDI-MS can tolerate a higher amount of salt than electro spray ionization mass spectrometry ( ESI-MS) . Also, the addition of salt can enhance the HALDI-MS signal intensity of the complex ion of α-lipoic acid and β-cyclodextrin, and we suggest that such signal-enhancement effect is due to the formation of the three component complex consisting of α-lipoic acid,β-cyclodextrin and the positive ion of the salt.

Objective To investigate the effects of ult rasonic cavitation on cell membrane cultured in vitro. Methods The rat pulmonary artery vascular smooth muscle cells were divided into three groups, control group, simple ultrasound radiation group and contrast plus ultrasound radiation group.The latter two groups were exposed to ultrasound(665 kHz, 0.5- W/cm 2) for 20 s but the last group with contrast agent. Immediately after the experiment or 24 hours after treatments, electron microscopic scanning was used to observe the membrane change. Results Compared with control group, the cell structure and cell surface had no apparent changes in the second group treated with ultrasound alone. In the third group, nearly 20% cells exhibited small holes with diameter mostly about 1-2 ?m in the cell surface and returned to normal appearance after 24 hours later. Conclusions Ultrasonic cavitation can cause small transient holes in cell surface and hence increase permeability of the cell membrane. It might be the main mechanism for gene delivery with ultrasound contrast agents.
10. Investigation of Drug Zero Bonus Present Situation in a County -level Public Hospital in Henan Province
Chinese Pharmaceutical Journal 2017;52(15):1367-1372
OBJECTIVE: To study the effect of "cancel drug addition" policy in county public hospitals, and to provide reference for further improvement of relevant policies. METHODS: This paper compares the data of medical expenses control, hospital income and expenditure, compensation and so on before and after the policy of "canceling the drug addition" of a county public hospital to study the actual effect of policy implementation. RESULTS: The proportion of drugs after the implementation of the decline, from the policy before the implementation of 43.6% to the policy objectives (30%). The total cost of drug growth rate is lower than before the implementation of the policy, the slowdown in growth; outpatient average medical expenses, inpatient per capita reduction in drug costs, the difference was statistically significant. The average cost of medical care was increasing, and the growth rate dropped first and then rose, which was close to the level before the implementation of the policy. At the same time, the income structure of the county-level hospitals tends to be reasonable, but the balance of payments has dropped significantly. The increase in hospital investment and adjust the price of medical services increased hospital income is not enough to make up for the "cancellation of drug additions" brought about by the loss. CONCLUSION: "Cancellation of drug addition" policy in the county-level public hospitals since the implementation of the control of medical expenses have a certain role in the control of drug costs growth effect is obvious. Patient medical expenses are falling. In order to consolidate the effectiveness, but also the establishment of multi-share long-term compensation mechanism, while paying attention to the increase in medical staff income.
