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).

AIM: To investigate the effects of stress on the opening of mitochondrial membrane permeability pore (PTP) in rat heart and explore the possible molecular mechanism underlying PTP opening. METHODS: Stress animal model was established. After strained for differnet time, all rats were killed and PTP opening degree were examined by spectrophotometer. Bcl-2, Bax expression levels were determined by Western blot. RESULTS: Stress induced PTP opning, Bcl-2 expression inhibition and Bax level elevation in myocardial mitochondria. CONCLUSION: PTP opening was the important mitochondrial mechanism of stress-induced heart injury. Decrease in Bcl-2 expression and increase of Bax level may be an important molecular basis for PTP opening.

BACKGROUND: Chronic obstructive pulmonary disease(COPD) is characterized of chronic inflammation in airway, pulmonary parenchyma and pulmonary vessels. The mechanism of the increment and activity changes of these inflammatory cells is unclear at present.OBJECTIVE: To study the apoptotic character of peripheral blood polymorphonuclear neutrophils(PMNs) and its relationship with COPD to provide a reference for early intervention and function surveillance for COPD patients.DESIGN: An observatory comparative study based on COPD patients and healthy population as controls.SETTING: Department of pulmonary medicine in a military medical university of Chinese PLA affiliated hospital.PARTICIPANTS: Totally 98 COPD patients were admitted by the Department of Pulmonary Medicine, Research Institute of Surgery, Daping Hospital, Third Military Medical University of Chinese PLA between February 2003 and December 2003 due to COPD acute attack. Eighteen patients including 12 males and 6 females aged between 48 and 70 years old [mean of(56 ± 7) years old]were randomly selected into COPD group according to random number table.Totally 14 healthy adults including 10 males and 4 females aged between 50 and 70 years old [mean of (59 ± 8) years old] who were individuals came for physical check up in our hospital were selected in control group.METHODS: PMNs were separated from peripheral blood by density gradient centrifugation. The dynamic changes of PMNs apoptosis in peripheral blood was observed by flow cytometer and TUNEL method.MAIN OUTCOME MEASURES: Comparison of PMNs apoptotic rate in peripheral blood among groupsRESULTS: As indicated by flow cytometric analysis, PMNs apoptotic rate at early apoptotic phase in COPD patients at paracmasis was(8.5 ± 1.3)%,which was significantly lower than(12.5 ± 1.8)% of normal control group( t=6.25, P < 0. 01); PMNs apoptotic rate was(5.1 ±0.6)% at acute aggravation stage, which was significantly lower than that of paracmasis group ( t =5.66, P <001). As indicated by TUNEL analysis, PMNs apoptotic rate at paracmasis was(12.42 ±2.7)% , which was significantly lower than (21.5±4.8)% of normal control group(t=5.76, P < 0.01); PMNs apoptotic rate was(4. 9 ±0.4)% at acute aggravation stage, which was significantly lower than that of paracmasis group( t = 6. 12, P < 0. 01 ) . PMNs changes at the late phase of apoptosis/necrosis had a contrary tendency, i. e.,PMNs rate at late apoptotic phase/necrosis was(2. 8 ± 0.5)% in COPD patients at paracmasis, which was significantly higher than(1. 3 ±0.4)% of normal control group ( t= 6. 37, P < 0. 01 ); PMNs rate was (3.7 ± 0. 3) % at acute aggravation stage, which was significantly higher than that of paracmasis group(t=5.81, P <0.01).CONCLUSION: PMNs abnormal apoptosis might be an important reason that induces PMNs aggregation in airway and lung tissues in COPD. This process might have an important significance in the generation and development of chronic airway inflammation, which provides an etiologic basis for the primary rehabilitative intervention of COPD.

Objective To study the protection mechanism of HO-1 with the gas-blood analysis and MAP of femoral artery in rats with hemorrhagic shock.Methods A model of hemorrhagic shock was established in 20 SD healthy clean male rats.The rats were randomly divided into the L.Lactis recombinant HO-1 gene group (HO group)and phosphate buffer solution group (PBS group).The gas-blood analysis and MAP of femoral artery in hemorrhagic shock were compared during the test.The mortality rate,MPO activity,bacterial translocation,the pathologic and content of HO-1,TNF-α and IL-10 in the low intestine were detected and compared 1h after resuscitation.Results Compared to PBS group,the mortality rate,Chiu's grade,bacterial translocation and MPO activity in HO group were significantly decreased[10% vs40%,(1.51 ±0.23) points vs(2.15 ±0.48) points,44.4% vs 100.0%,(0.16 ±0.05)U/g vs (0.99 ± 0.28)U/g,all P <0.05],PaO2 and MAP during the resuscitation,the content of HO-1 and the gray level of IL-10 were significantly increased.Conclusion L Lactis recombinant HO-1 gene has the virtue to maintain the higher level of PaO2 and MAP,which is beneficial to the intestine mucosa barrier and anti-inflammation response of low intestine significantly.

OBJECTIVE:To provide reference for the generalization of automatic unit-dose tablet sorting and counting machine (ATM) in hospital pharmacy. METHODS: The preparative work and the working procedure of the ATM were introduced, and the advantages, the causes of medication errors and the problems related to the application of the ATM were analyzed. RESULTS: ATM helped to enhance the dispensing efficiency, improve the sanitation of drugs, ensure drug safety to great extent and improve the drug control. However, sometimes it might bring about medication errors. 236 (0.48%) of the total 49 059 medical orders analyzed in our study were found to be of medication errors. CONCLUSIONS: ATM has great application value. The wide use of ATM is consistent with the tendency of pharmacy automation, yet its use remains to be further improved.

Aim To explore the mechanisms of lovastatin protecting EPCs.Methods EPCs were preincubated with lovastatin or LOX-1 mAb for 24 h and then exposed to oxLDL for 48 h.The abilities of migration,adhesion,and tube structure formation of EPCs were examined.To explore the mechanisms,the level of NO,the expression of eNOS and LOX-1 protein and mRNA were assayed.Results Incubation of EPCs with oxLDL resulted in the impairment of migration,adhesion and tube structure formation.Furthermore,oxLDL caused the decrease of NO generation,the down-regulation of eNOS mRNA and protein expression,the up-regulation of LOX-1 mRNA and protein expression.However,the detrimental effects of oxLDL on EPCs function were attenuated by lovastatin and LOX-1 mAb.Moreover,the effects of oxLDL on NO generation,eNOS and LOX-1 expression were reversed by lovastatin and LOX-1 mAb.Conclusion Lovastatin protects EPCs by the regulation of eNOS and LOX-1 expression.
