OBJECTIVE:To raise the price fixing of drugs to a scientific and reasonable level.METHODS:From the view of the whole society,the economic efficiency of newly-developed drugs and original drugs was compared with cost-effec?tiveness analysis.RESULTS&CONCLUSION:Through comparison,the price ranges with economic efficiency of newly-de?veloped drugs would be obtained,which could guide the price fixing.

OBJECTIVE:Using the result of pharmacoeconomic evaluation to instruct the management of drug prices.ME_ THODS:Establishing a reference price and combining economic benefit to decide the price of a drug.RESULTS&CONCLU_ SION:According to the rational value scope,the prices of new drugs can be fixed.A reasonable and timely adjustment of the price can be made.

Objective:To analyze the influencing factors of investment management of hospital intangible assets,so as to provide countermeasures for establishing and optimizing the investment management system of hospital intangible assets.Methods: Taking hospital reputation as an example,we analyzed its role in the investment management of hospital intangible assets and the maintenance of hospital reputation in an economic perspective using Shapiro model and game theory.Results: The factors,such as the blueprint of hospital,efficiency of medical quality information transmission,and cost variance,all influenced the reputation of hospital.Conclusion: In the health care field,stable property right system should be established and market information agents should be cultivated.The administrative actions of involved departments should abide by the related regulation and the running system of hospitals should be optimized.

Objective To study the reconstruction and secretory function of the grafts after adrenal transplantation using fetal rats as donors.Methods Thirty adult SD rats randomly received sham operation(group A),excision of bilateral adrenals(groups B,C,D and E),and additionally adrenal transplantation in groups C,D and E using fetal rats aged 16,18 and 20 days respectively as donors.Results The weight of group A got down to the lowest at the 3rd week,and restored to the preoperation level at the 4th week after sham operation.The weight of group B gradually rose up within 4 weeks.The weight of groups C and D rose up in the first 2 weeks,then down.The weight of group E rose slowly within the first 3 weeks,then down.The serum level of corticosterone decreased sharply in group B after operation,while that of groups C,D and E went down obviously in the first 2 weeks,then up,but that in group C was significantly lower than that in groups D and E.Microscopically,we found the capsule of allografts thicken and underneath many proliferative cells and well-constructed glomerular and fascicular zone 4 weeks after operation.Conclusion After transplantation,the fetal adrenal could survive and reconstruct well,and its secretory function gets better gradually.The graft from the elder donor is better than that from the younger in reconstruction and secretory function,but shows no obvious difference in immunological rejection.

Objectives:To observe the effect of intrahepatic cholestasis on the development and growth of fetus in pregnant rats. Methods: The animal models of intrahepatic cholestasis were made by injecting benzogynestryl (5 mg/kg body weight) or cholate (2.4 mg/kg body weight) for 5 days starting from 16th day of pregnancy. Biochemical parameters of fetal plasma and amniocent were determined at the 21st day of pregnancy. The pathological lesion of placenta in rats was also observed. Results: Cholic acid group showed lower body weight and high level of estrodiol in fetal plasma with high metaphase mortality of fetus. The level of TBA in amniocent was high in estrodiol group compared with normal control group. Pathologically, placenta edema and chorion denaturalization and necrosis with infiltration of neutrocyte were observed in both groups. Conclusions: Intrahepatic cholestasis is detrimental to the development and growth of fetal rats in pregnancy rats.

We proposed a multi-resolution-wavelet-transform based method to extract brainstem auditory evoked potential (BAEP) from the background noise and then to identify its characteristics correctly. Firstly we discussed the mother wavelet and wavelet transform algorithm and proved that bi-orthogonal wavelet bior5. 5 and stationary discrete wavelet transform (SWT) were more suitable for BAEP signals. The correlation analysis of D6 scale wavelet coefficients between single trails and the ensemble average of all trails showed that the trails with good correlation (> 0. 4) had higher signal-to-noise ratio, so that we could get a clear BAEP from a few trails by an average and wavelet filter method. Finally, we used this method to select desirable trails, extracted BAEP from every 10 trails and calculated the I-V inter-waves' latency. The results showed that this strategy of trail selection was efficient. This method can not only achieve better de-noising effect, but also greatly reduce the stimulation time needed as well.

Objective The study was designed to investigate the effect of atomization inhalation of Qingjin-Huatandecoction on prevention of elderly patients’ postoperative pulmonary complications after thoracotomy.MethodsA total of 60 elderly patients with thoracotomy were randomized into 2 groups. Both groups of patients were treated with oxygen uptake, anti-infection, antispasmodic, analgesic, and nutritional support. Based on the conventional treatment, the control group was added with atomization inhalation of mucosolvan and dexamethasone, while the treatment group with atomization inhalation ofQingjin-Huatan decoction. The volume of phlegm, serum CRP, TNF-α level and absolute neutrophil count (ANC), arterial blood gasanalysis, and records of the pulmonary complications were meausred.Results The pH value at Day 3 (7.39 ± 0.06vs. 7.36 ± 0.05,t=2.120), the PaO2at Day 3 (86.51 ± 3.96 mmHgvs. 84.07 ± 3.51 mmHg,t=2.520) and Day 5 (92.27 ± 2.94 mmHgvs. 90.40 ± 3.08 mmHg,t=2.400) of treatment group were significantly higher than those of the control group; the PaCO2at Day 3 (44.57 ± 2.53 mmHgvs. 46.39 ± 3.35 mmHg,t=2.390) and  Day 5 (40.77 ± 2.48 mmHgvs. 42.42 ± 3.33 mmHg,t=2.130) of treatment group were significantly lower than those of the control group. The serum CRP at Day 3(8.26 ± 2.38 mg/Lvs. 9.76 ± 2.37 mg/L,t=2.440) and Day 5 (6.94 ± 1.76 mg/Lvs. 8.15 ± 2.38 mg/L,t=2.250), the ANC at Day 3 (8.54 ± 1.85)×109/Lvs. (9.58 ± 1.94)×109/L, t=2.140) and Day 5 (6.54 ± 1.85)×109/Lvs. (7.58 ± 1.95)×109/L,t=2.160), the serum TNF-a at Day 5 (7.54 ± 1.38 mg/Lvs. 8.43 ± 1.36 mg/L,t=2.540) of treatment group were significantly lower than those of the control group. The sputum volume at Day 3 (50.74 ± 18.46 ml/dvs. 59.92 ± 15.25 ml/d,t=2.099) and Day 5 (39.64 ± 18.21 ml/dvs. 48.99 ± 13.55 ml/d,t=2.256) of treatment group was lower than that of the control group. At Day 5, the pneumonia (3.33%vs. 20.00%,t=4.043) and the atelectasis (6.67%vs. 26.77%,t=4.320) of treatment group were significantly lower than those of the control group(P<0.05).ConclusionAtomization inhalation ofQingjin-Huatandecoction can improve pulmonary function of postoperative pulmonary complications of elderly patients after thoracotomy, take control of inflammation and the occurrence of postoperative pulmonary complications.

The core problem of current rural health services is a governance problem, that is, how the basic rural health resources can be used more effectively. Based on the study of history and reality, this paper suggests that in the existing “government-market” framework, the village is the third perspective worthy of consideration. Inside the village community, the trust, network and cooperation between people which were based on the traditional rural acquaintances society capital and the institutional resources in the organizations at the primary level will be able to in-crease the degree of organization, thereby reducing the transaction costs between the government or the market and rural residents. The village power will be able to better take advantage of government and market mechanisms, and thus solve the problem of rural health resource utilization more effectively.
