Objective To observe and compare the efficacy and safety of chloroprocaine and ropivacaine for epidural labor analgesia.Methods 86 cases of voluntary acceptance of maternal painless natural childbirth were selected in the study.43 cases were given chloroprocaine epidural analgesia (chloroprocaine group),and the other 43 cases were given ropivacaine epidural analgesia (ropivacaine group).The pain (VAS score),lower limb motor block degree(MBS score),fetal heart rate(FHR) and contractions duration of maternal prenatal and medication immediately after 10min,20min,40min,80min were compared between two groups.The first,second and third stage of labor and fetal output after 1 min,5min,10min Apgar score were compared.The incidence of adverse events were observed.Results In the chloroprocaine group,the 10min VAS score was (2.10 ± 1.02),which was significantly lower than (4.31 ± 1.13) in the ropivacaine group (t =4.565,P ＜ 0.05).In the chloroprocaine group,analgesia 20min MBS score was (0.24 ± 0.03),which was significantly higher than (0.11 ± 0.04) in the ropivacaine group (t =4.126,P ＜ 0.05).In the chloroprocaine group,4 cases occurred nerve injury,which was more than the ropivacaine group (1 case),the difference was statistically significant (x2 =4.263,P ＜ 0.05).Conclusion Chloroprocaine and ropivacaine for epidural labor analgesia have superior efficacy and the clinical efficacy is similar.Chloroprocaine has the advantage of quick results,but the medication about 20min time period that the drug might lead to a greater degree of lower limb motor block,and has the risk of nerve injury,pregnant women can choose according to their medication.

Objective To explore the effect of Fuke Qianjin Tablets on quality of life and clinical efficacy in patients with endometriosis uterina post-operation.Methods 76 cases with endometriosis were collected and divided into the control group and the treatment group, 38 cases in each group.The two groups were based on the location of endometriosis lesions to the implementation of surgical resection, the control group was given the Gestrinone Capsules 2.5 mg orally post-operation, twice weekly, the treatment group was given Fuke Qianjin Tablets 6 tablets, 3 times per day at the first day after first menstruation, 21 days for a course, a total of two treatment cycles.Clinical curative effect, postoperative quality of life and adverse reactions were compared after treatment.Results Compared with the control group, treatment group, the clinical total efficiency of the treatment group was higher (P<0.05),the sexual desire, sexual arousal, orgasm, sexual psychology, abnormal sexual behavior, and BISF weighted scores were increased in 2 groups ( P <0.05 ) , compared with the control group, sexual desire, sexual arousal, orgasm, sexual psychology, abnormal sexual behavior, and BISF weighted scores of the treatment group were higher (P<0.05).there was no statistically significant difference in adverse reactions between two groups.Conclusion Fuke Qianjin Tablets have significant therapeutic effect in the treatment of endometriosis uterina, can also improve the quality of life after surgery.

Objective To determine the effects of endogenous testosterone on early atherosclerosis of coronary artery in castrated rabbits fed with high fat diet.Methods 30 adult male New Zealand white rabbits were randomly allocated to three groups:castrated group,physiological level group [6mg/kg intramuscular injection of testosterone undecanoate(TU)after cas tration,once every two weeks] and sham operation group.All animals were fed with high fat diet,but only the animals in both castrated group and physiological level group were castrated(bilateral castration)reproduce models with different testosterone levels.Serum total testosterone and estradiol,serum lipids and lipoproteins were determined 12 weeks after model establishment.The intimal thickness of coronary and kidney artery were measured and analyzed.Results The average level of serum TC,TG,LDL-C,ApoB,LDL-C/HDL-C and ApoB/ApoA1 were higher in castrated group than in sham operation group and physiological level group(P0.05).Conclusion The decrease in endogenous testosterone provokes early atherosclerosis of coronary artery in male rabbits fed with high fat eiet.

Objective To investigate the effect of castration on heart function in male rabbits postinfarction congestive heart failure model. Methods 32 male 4-5 months old New Zealand rabbits were randomly assigned to ligation of first branch of left coronary artery or sham operation (sham group, n=8). 3 weeks later 20 survived MI model rabbits were randomly subjected to castration (castration group, n=10) or sham operation (MI group, n=10). Serum FT, DHEAS levels and LVEF were checked at week 0, 3 and 15. Heart diameter and left ventricular wall thickness were measured at week 15. Results The serum FT and DHEAS levels decreased significantly at week 3. In MI group and castration group serum androgen level was lower and heart weight, ventricular diameters, ventricular wall thickness corrected by body weight were higher than that in sham group at week 15. The androgen level and body weight of castration group were lower than that in MI group. But LVEF in castration group was not higher than MI group. Conclusion There was no benefit effect of castration on heart function in male rabbits postinfarction congestive heart failure model.

OBJECTIVE:To analyze the medico-ethical problems of epilepsy from Medi-ethics and its effect on improving the quality of life of the persons with epilepsy.DATA SOURCES:Articles were computer-searched from Chinese Journal of Medico-ethics, Chinese Journal of Clinical Neurology, Chinese Medical Journal, Chinese Journal of NeuroMed, Chinese Journal of Nerval Mental Disorder from January 1989 to December 2004 with the key words of "epilepsy, medico-ethics and social discrimination". And the language was restricted to Chinese. And we also selected two books, which were Bioethics written by Shen Ming-xian, and The Prevention and Therapy of Epilepsy written by Zhou Zheng-xin for reference.STUDY SELECTION: From all the preliminarily screened papers, 98 papers were obtained related to epidemiology, sociology and ethics.DATA EXTRACTION: Repeated and similar papers were excluded. 10 papers and books were selected from the 98 papers, which touched upon the problems of the epileptics and their life quality. The 10 papers have involved many cross discipline subjects, such as Bioethics, Medico-ethics,and Socio-ethics, which provided more concern about the epileptics from multiple directions.DATA SYNTHESIS: Ethics indicate the principles and guidelines for relationships between people. The ethics explored here refer to normative ethics. Generally, the basic ethical principles are: respect, beneficialness,balance and justice. Since some epileptic patients lack in the knowledge of epilepsy and proper treatment and suffer from discrimination in the health care, more untreated and non-proper treatment, doctors and nursing persons should take the attitude of being beneficial to the patients. Medication for the epileptics, especially the female patients at the first period of pregnancy, the incidence of the deformed children was high. Should the principle of beneficence be applied to mothers or children? The number of the operative treatment was more and more in patients with epilepsy, while surgery itself is a risk behavior .If there is no better method to choose, and all the available choices have their advantage and disadvantages. Physicians can only choose the better one from the two kinds of harm, trying to make the patientssuffer the least harm with the largest effect. Aggressive behaviors can be observed during seizure or unconsciousness state. Controlling the moving range of the patients with epilepsy consciously is in accord with the general ethical behavior, on the contrary, confinement disobeys the morals and the curative effect is not good. The extreme behavior of the patients with epilepsy is suicide and occurred more in unemployed, unmarried and living alone, male, and patients with mental disorders in epilepsy. The direct reasons of suicide are unemployment, low social status, and little understanding and care from their communities, families and friends.The sensible ethical principle for epileptics is to treat the patients as normal people in the society.CONCLUSION: Epileptic crowd need care from the society, family and other factors. Proper considering ethical principle in treating the population is the humane solicitude and to help the patients regain health and improve the life quality.
