Objective To align the mapping points from the locations of catheter electrodes with CT/MR image three-dimension data of the cardiac chamber. Methods Most of existing algorithms assumed that two spaces spanned respectively by mapping points and by CT/MR data were orthogonal, and thus modulated only 9 free-degrees of three-dimension translations, rotations and scaling for registration. However, our research showed that the above two spaces might be not always orthogonal. So we introduced affine transformation model based on 12 free-degrees and the corresponding iterative closest point algorithm to realize the registration and further incorporate the registration algorithm with the clinical operations. Combining with OpenGL, we realized the proposed algorithm via Visual C]+]+ 6.0 software. Results Simulation results showed that the residual registration errors on average were decreased from 40 pixels before registration to 1.5 pixels after registration. This algorithm was further validated in animal experiments. Conclusion This proposed three-dimension mapping registration algorithm well realizes the registration in three-dimension cardiac mapping and has practical application values.

The latest literatures on eslicarbazepine acetate in the treatment of epilepsy from home and abroad were referred. The results showed that the oral absorption of eslicarbazepine acetate is quick with long half life, linear pharmacokinetics and low potential of drug-drug interactions. Compared with carbamazepine and oxcarbazepine, eslicarbazepine acetate is more effective against epilepsy.

Referred to the latest literatures on raltegravir from home and abroad, the effect and safety of raltegravir in the treat-ment of AIDs were reviewed. The results showed that raltegravir was a necessary component for the initial treatment and repeated treat-ment of AIDs. Up till now, there was no report on its serious adverse reactions and drug interactions.

Objective To observe the clinical efficacy of therapy of nourishing kidney and liver for the treatment of hypomenorrhea with the syndrome of kidney deficiency and liver stagnation. Methods Fifty-one hypomenorrhea patients with the syndrome of kidney deficiency and liver stagnation were randomized into treatment group(N =25) and control group (N = 26). The treatment group was treated with oral use of Yangyin Shugan Capsules (mainly composed of Radix Bupleuri, Radix Paeoniae Alba, Radix Rehmanniae Preparata, and Fructus Ligustri Lucidi). The control group was given placebo capsules orally. After treatment for 8 weeks , the overall efficiency and therapeutic effect on menstruation of the two groups were evaluated according the changes of traditional Chinese medicine(TCM) symptom scores. Results(1) The total effective rate of the treatment group was 84.0％, and that of the control group was 15.4％, the difference being significant between the two groups (P < 0.01). (2) The effective rate on the menstrual volume and menstrual color and texture of the treatment group was 64.0％, 68.0％, and that of the control group was 7.7％, 15.4％ respectively, the difference being significant(P < 0.01). However, the difference of effect on improving menstrual period was insignificant between the two groups (P > 0.05). Conclusion Therapy of nourishing kidney and liver is effective for the treatment of hypomenorrhea with the syndrome of kidney deficiency and liver stagnation, and has obvious effect on improving menstrual volume and TCM symptoms.

Discussed in the paper are case-based payment practice in China,and outcomes of this practice for the past ten years.The authors pointed out that compared with DRGs,such a practice is exposed to such risks as low coverage of diseases,incompatible policies,defective pricing method,and lack of comprehensive evaluation.It indicates that China is on the initial stage of case-based payment reform which should be promoted with reference to international experiences.

Objective To investigate clinical efficacy of different ventilator parameters on acute left heart failure.Methods One hundred and nineteen patients with acute left heart failure were randomly divided into A,B,C,D group.Patients in A,B,C,D groups were treated separately with higher air pressure,high pressure,medium pressure or low pressure respectively.In each group,clinical efficacy,heart rate (HR),arterial partial pressure of oxygen (PaO2),pulse oxygen saturation (SpO2),partial pressure of carbon dioxide (PaCO2) and pH were measured.Results There were significant differences among the four groups in terms of HR,PaO2,SpO2,PaCO2 and pH (F =32.21,29.46,12.34,36.47,18.38 ; P ＜ 0.05).Compared with that in A,C and D group,the levels of HR,PaO2,SpO2,PaCO2 and pH in B group were significant difference (P ＜ 0.05).Meanwhile those indices in B group were difference among before and after treatment (t =12.25,13.46,8.75,9.83,2.58 ;P ＜ 0.05).The efficacy rates of four groups were significant different (x2 =0.97,P =0.012),and in B group was 93.1％,higher than that of other 3 groups(71.0％,65.6％,51.8％ ;P ＜0.05).Condusion The ventilator parameters(10-15 cmH2O,55％-75％ FiO2 at beginning and later revised the FiO2 to 30％-40％) was proved to be worthy in treating acute left heart failure.

Through the improvement on determination of rhTNF-? bioassay, we established the formal procedure . Methods; We choose L929 cell for rhTNF-? bioassay determination. To identify the influence of rhTNF-? on the growth of HL-60 cells, various concentration and effecting time were studied. Results: The results showed that the inhibition of rhTNF-? on HL-60 cells based on dose and time. Northern Dot Blot and DNA electrophoresis showed c-myc gene was surpressed, and DNA was damaged by rhTNF-?. Conclusion: Autometic calculation is responsible for bioassay of rhTNF-?. rhTNF-? could inhibit the proliferation of HL-60 cells and its mechanism is different from doxirubicin.

Objective: To establish National Standard of rhTNF-? complying with the requirements of research and quality control. Methods: National Standard of rhTNF-? were assayed against international standard (NIBSC) of rhTNF-? by cytotoxicity bioassay (L929 ) in vitro. The collaborative study has been carried out among four laboratories. Results: Based on the statistical analysis the results show that mean pf 95 % confidence interval is 3 289 ~ 4 266 IU per ampoule; the 95 % reference range is 1 735 ~ 8 087 IU per ampoule. Based on this study, the potency of rhTNF-? standard is defined as 3500 IU per ampoule. Stability tests indicate that the bioactivity has not been changed significandy under the storage of four different temperautres for 27 monthes. Conclusion: The preparation of rhTNF-? met the requirement of quality and could be used as a National Standard.

By using of combined HRP retrograde tracing and immunocytoche mistry methods, the projection from the caudal part of the ventrolateral medulla (VLM) to the nucleus accumbens (Acb) was examined. When HRP was injected into the ventral and medial area of the caudal part of Acb, the labeled cell bodies were mostly found in the bilateral (predominantly ipsilateral) caudal part of the VLM. When HRP technique (HRP injected into the Acb)was combined with immunocytochemical method, many HRP-TH, HRP-NT and HRP-CCK double labeled cell bodies were found in the VLM. The number of the HRP-TH double labeled cell bodies were numerous, while HRP-NT and HRP-CCK doublelabeled cells were less. HRP-TH double labeled neurons were also found in the reticular formation between the solitary tract nucleus and VLM.
