Objective To discuss the application value of the treatment protocol of combining warm needling and atorvastatin in treating female cardiac syndrome X (CSX). Method Eighty female CSX patients were randomized into a control group and an observation group by the random number table, 40 cases in each group. The control group was intervened by atorvastatin in addition to the conventional treatment protocol, while the observation group was by warm needling plus atorvastatin in addition to the conventional treatment. The treatment efficacies and adverse events rates were compared between the two groups. Result There were no significant between-group differences in comparing the component and total scores of the Cardiac Anxiety Questionnaire (CAQ), NO, plasma endothelin (ET-1) and hypersensitive C-reactive protein (hs-CRP) levels before the intervention (P>0.05);after 8-week treatment, the component and total scores of CAQ, ET-1, and hs-CRP levels were significantly lower in the observation group than in the control group, and NO level was significantly higher in the observation group than in the control group (P<0.05). Meanwhile, at the end of the 8-week treatment, the total effective rate of the observation group was significantly higher than that of the control group (P<0.05). Besides, there was no significant difference in comparing the adverse events rate between the two groups during the 8-week treatment (P>0.05). Conclusion In the treatment of female CSX, warm needling plus atorvastatin can enhance the treatment efficacy.

Background Hypertension,ischemia and hypoxia induce the increase of glutamate level in eye tissue and furthermore produce excitatory damage and apoptosis of retinal ganglion cells(RGCs).At present,the study on the protection of traditional Chinese medicine on glutamate-induced retinal excitatory damage is lack.objective Present study was to explore the protective effects of Huoxue huayu decoction,a Chinese herbal recipe,on RGCs in acute ocular hypertension model. Methods Fony-five healthy clean Wistar rats were divided into three groups randomly.The acute ocular hypertension models were established in 40 Wistar rats by injecting the normal saline solution into the anterior chamber to elevate the intraocular pressure for 60 minutes.Huoxue huayu decoction of 4 ml was administered intragastrically once per day in 20 model rats.Other matched 5 normal Wistar rats served as normal control group.The rats were sacrificed on 1,3,7 and 14 days after modeling and the retinas were isolated for the histopathologieal and uhrastructure examination.Expression of glutamate transporter in the retina of acute ocular hypertension and normal rat retina were detected using quantitative real-time polymerase chain reaction.The utilization of animals followed the Association for Research in vision and Ophthalmology. Results After acute ocular hypertension.the retina thickness attenuated and the numbers of RGCs decreased under the light microscope in 1,3,7 and 14 days after modeling in comparison with normal control rats.The degradation of the organelle and edema as well as changes of cell nuclei were seen in model rats under the transmission electron microscopy.The expression of glutamate transporter mRNA in model group and glutamate transporter group was rapidly elevated in the first day (P<0.05),descended at the third days(P<0.01)and returned to the normal level 7 days later(P>0.05).Conclusion Huoxue huayu decoction can protect the retina against RGCs damage in the acute ocular hypertension by elevating the expression of glutamate transporters in retina.

BACKGROUND: Patients with amnestic mild cognitive impairment (MCI)were considered to be going to develop into Alzheimer disease, and were the high-risk group of Alzheimer disease.OBJECTIVE: To study the implicit and explicit memory in the patient with amnestic MCI. DESIGN: Homochronous and controlled observation.SETTING: Neurological Department of the Southern Building of General Hospital of Chinese PLA.PARTICIPANTS: The research was carried out at Neurological Department of the Southern Building of General Hospital of Chinese PLA from January to June 2003. Totally 20 male patients with amnestic mild MCI,with the average age of (78.7±4.9) years and the average educational time of (8.2±1.0) years, selected from neurological out-patient clinic and ward of southern building of General Hospital of Chinese PLA, Complaint memory losing and confirmed by the relatives and close friends of the patients, Mini-mental state examination (MMSE) ≥24, activity of daily living (ADL)＜26, and clinical dementia rating equal to 0.5, Objective memory examination score reduced compared to the examiners' educational background,the memory quotient recorded by clinical memory sheet to be 63-77 (lower than the normal value with 1.5-2.5 standard deviation), were accepted, and determined as experiment group.Totally 20 healthy male veterans selected from Beijing area, with the average age of(77.9±4.7) years and the average educational time (8.1±1.1) years were selected as control group. All subjects volunteered to take part in_the examination.METHODS: Explicit memory included word free recall and re-recognition task. The Chinese characters were selected from the 1000 most commonly used ones in the books of primary and middle schools. The 30 double characters-words were chosen and randomly divided into two tasks. Recall task included 10 double character words that were target words. Re-recognition task included 20 double character words, of which one half were target words, and the other half were interfering words. Implicit memory included word free recall and character-root-complementary task. The Chinese characters were from the same source as mentioned before. Thirty Chinese characters were chosen in free recall task at beginning. These Chinese characters at least had possibility of composing over 4 commonly used double character-words in primary and middle school books. One double-Chinese character-word in four possibilities was randomly selected and the total was 30 words. Then these 30 words were divided into two groups, one was target group and the other was interfering word. All selected Chinese characters were composed either up-down structure or right-left structure. Taking a part of the Chinese character would leave a characterroot. There were 30 character-roots and they were never the same each other.There were at least four possibilities to form a Chinese character for each root as properly matching among 1000 commonly used Chinese characters.At first, the subjects were asked to read the target words loudly for 3 times in 4 tasks and tried to remember all the target words (characters) and were told to test their memorization later on. The target words (or characters)would appear in one-minute interval. The subjects were asked to repeat the words (or characters) appeared before as many as possible based on their memory in free recall task and they did not have to remember the words (or characters) in order. The correct recall rate for 10 target words was calculated. In re-recognition task, the target words and interfering words were mixed up and appeared one by one in random order and the subjects were asked to tell if the words appeared before. The correct rate of 20-word rerecognition was calculated. In free recall task, the first character in target words was mixed with the first character in interfering words and they appeared one by one in random order. The subjects were asked to form any two-character-word with appeared Chinese characters and wrote down the first word thought of in test sheet. The hitting rate of target words and interfering words were calculated. t-test for independent samples was carried 9ut respectively between the two groups.MAIN OUTCOME MEASURES: ① Semantic priming effect (the hitting rate of target words in word free recall task and the hitting rate of interfering words) and apperception priming effect (the hitting rate of target words in character-root-complementary task and the hitting rate of interfering words) in the two groups. ② Difference of explicit memory (correct rate of free recall and correct rate of re-recognition) and difference of semantic and apperception priming effect in the two groups.RESULTS: All subjects in the two groups completed the test and entered the final analysis. ① Results of inner-group analysis: In the group of MCI,the hitting rate (0.41±0.15) of target words in word free recall task was significantly higher than that of interfering words (0.31±0.12, P ＜ 0.01),suggesting that there existed semantic priming effect in the patients with amnestic MCI as completing this task. In the character-root-complementary task, the hitting rate of target words (0.17±0.10) was significantly higher than that of the hitting rate of interfering words (0.10±0.07, P ＜ 0.05), suggesting that there existed perceptional priming effect in the patients with amnestic MCI as completing this task. In the control group, the hitting rate of target words (0.45±0.11) was significantly higher than that of the interfering words (0.33±0.10, P ＜ 0.01), suggesting that there existed semantic priming effect in the elderly with normal perception as completing this task as well. In the character-root-complementary task, the hitting rate of target characters (0.18±0.08) was higher than that of interfering characters (0.13±0.07, P ＜ 0.05), suggesting that there existed perceptional priming effect in the elderly with normal perception as completing this task as well. ② Results of inter-groups analysis: Correct rates of free recall and re-recognition in the MCI group was decreased (0.10±0.09, 0.45±0.13,t=9.858, P=0.000; 0.69±0.14, 0.83±0.08, t=3.685, P=0.000). There was not significantly different in Sementic priming effect and perceptional priming effect both in the MCI group and the control group.CONCLUSION: Sementic priming effect and perceptional priming effect were existed both in the MCI experiment group and the control group, but the implicit memory was not significantly different in the two groups. However, the patients with forgetful style MCI were exhibited a decline in explicit memory. Memory function of mild MCI patients was shown double characteristics, i.e. damage of explicit memory and preservation of implicit memory. The double character in memorial function provided theoretical basis for the rehabilitative training of MCI patients.
