2.Research on Registration Algorithm for Three-dimension Cardiac Electrical Maps
Space Medicine & Medical Engineering 2006;0(06):-
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.
3.Clinical Observation of Therapy of Nourishing Kidney and Liver for Hypomenorrhea with Syndrome of Kidney Deficiency and Liver Stagnation
Journal of Guangzhou University of Traditional Chinese Medicine 2017;34(5):654-658
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.
4.Recent Development of Eslicarbazepine Acetate, a New Drug against Epilepsy
China Pharmacist 2015;(3):471-473
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.
5.Effect and Safety of Raltegravir in the Treatment of AIDs
China Pharmacist 2015;(1):139-141
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.

Exosomes are extracellular nanovesicles secreted by a variety of cell types such as cardiomyocyte, hepatocytes, and stem cells. They carry specific sets of mRNA, microRNA, and proteins, which play a role in intercellular communication in almost each physiological and pathological process. Exosomes, which are released after tissue cell injury, can initiate repair/regeneration responses by triggering inflammation and active fibroblast, and finally lead to tissue fibrosis. However, exosomes released by stem cells can retard tissue fibrosis by enhancing cell survival and reducing apoptosis. In this paper, we reviewed the research progress in the relationship between exosomes and tissue fibrosis.

OBJECTIVE:To observe the efficacy of the reduced glutathione against hepatic lesion induced by antituberculotic agents.METHODS:A total of 226 patients with pulmonary tuberculosis undergoing short- course chemotherapy were randomly assigned to receive antituberculotic agents plus reduced glutathione throughout the course(treatment group,n = 114 cases) or to receive Inosine plus Glucurolactone(control group,n = 112).The patients were followed for 3~6 months with the incidence of hepatic lesion compared between the two groups.RESULTS:There were significant differences between the treatment group and the control group in the incidence of hepatic lesion,6 cases(5.3%) in treatment group vs.29 cases (25.9%) in the control group(P

Objective To determine blood/gas and tissue/gas partition coefficients of sevoflurane, isoflurane and halothane and evaluate the effects of pregnancy on them. Methods Ten 18-22 day pregnant and 10 non-pregnant SD rats were killed under pentobarbital anesthesia. The tissue specimens of heart, liver, kidney and brain were obtained and made into homogenates respectively. The blood/gas and tissue/gas partition coefficients of sevoflurane, isoflurane and halothane were determined using a method of 2-stage headspace equilibration by gas chromatography. Results Blood/gas and brain/gas partition coefficients were lower in pregnant group than in non-pregnant group (P

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 study the clinical efficacy of treatment of atrophic scars of facial hemangioma after isotopes radiotherapy with micro-plasma.Methods A total of 52 patients with atrophic scars were selected under micro-plasma treatment for 4 times,one time every six weeks.And their efficacies were evaluated by compared with single standard of that before and after the treatment.Results By means of rate of clinical index,the total effective rate of atrophic scars was 82.7%.The degree of improvement was as follows:cured in 53.8%,marked effective in 28.9%,effective in 17.3% and no case ineffective.The total effective rate of hyperpigmentation was 90.3%,including cured in 59.6%,marked effective in 30.8%,effective in 9.6% and no ineffective cases.Conclusions Micro-plasma is an effective therapy for atrophic scars of facial hemangioma after isotopes radiotherapy,which can significantly improve the depression degree of scars,eliminate the hyperpigmentation and improve the color of scars,but it only has adverse reactions of wound pain and postoperative wound erythema.
