OBJECTIVE: To study the effects of Anxin Granules on dyslipidemia in rabbits caused by high fat plus high cholesterol diet. METHODS: Thirty-two healthy New Zealand male white rabbits were randomly divided into 4 groups: normal control group, untreated group, Zhibituo Tablet-treated group and Anxin Granule-treated group. Rabbits in the normal control group were fed with regular chow, while rabbits in the other three groups were fed with high fat plus high cholesterol diet. Zhibituo Tablets and Anxin Granules were administered to the rabbits in Zhibituo Tablet-treated group and Anxin Granule-treated group at a daily oral dose respectively. At the end of the 10th week, the levels of serum total cholesterol (TC), triglycerides (TG), high density lipoprotein cholesterol (HDL-C), low density lipoprotein cholesterol (LDL-C), apolipoprotein A(1) (ApoA1) and apolipoprotein B (ApoB) were tested in each group, and the ultrastructures of the aorta were also observed by an electron microscope. RESULTS: Anxin Granules could reduce the levels of TC, TG, LDL-C and ApoB. The results observed by electron microscope showed that, as compared with the untreated group and the Zhibituo Tablet-treated group, the atherosclerosis of aorta in the Anxin Granule-treated group was lighter. And it was found that there were few lipid droplet vacuoles in cytoplasm of the endothelial cells, and various cell organs and elastic membrane were existed, but no lipid droplet vacuoles in cytoplasm of the medial smooth muscle cells. CONCLUSION: Anxin Granules can regulate the metabolism of blood lipid and inhibit the formation of atherosclerosis caused by hyperlipidemia in rabbits.

Objective To explore whether obese adolescents had neurochemical abnormalities in frontal lobe and hippocampus.Methods Anthropometric indicators were measured in all participants.Proton magnetic resonance spectroscopy(1H-MRS)were performed in 9 obese adolescents and 9 non-obese children as controls.Spectral peaks of N-acetylaspartate(NAA),creatine(Cr),choline(Cho)of 2 cortexes were measured and their ratios were computed and compared.Results Values of NAA and Cho in frontal lobe in obese group were significantly lo-wer than those of controls.There was no significant difference of Cr,NAA/Cr,Cho/Cr in frontal lobe and hippocampus between 2 groups.Conclusion The reduced NAA and Cho on 1H-MRS suggests that amount of neural nerve and myelination of white matter may be harmed in frontal lobe of obese adolescents.

Electronic case report forms (eCRFs) instead of the traditional paper case report forms (pCRFs) are increasingly used by investigators and sponsors of clinical research. We include a total of 14 phase III studies (8 pCRF, 6 eCRF) to compare paper and electronic data documentation both quantitatively and qualitatively in clinical studies. The result suggests that adaptions of electronic data capture (EDC) in clinical trials have the advantages in optimization of data capture process, improvement of data quality and earlier clinical decision compared to paper-based methods. Furthermore, the successful implementation of EDC requires accouplements with corresponding data management processes and reallocation of resources.

Objective To investigate the effect of Case Based Learning (CBL) method in clinical practice of internal medicine. Methods 88 clinical medicine students were divided into CBL teaching group and traditional teaching group. Traditional teaching method was introduced to traditional teaching group while CBL teaching method was carried out in the other. The test papers and questionnaires were analyzed in both groups. Result The students in CBL teaching group mastered internal medicine knowledge better than the other group. Conclusion CBL teaching mode helps improve the overall teaching quality of internal medical in clinical practice,and the interns' interest in learning and their clinical practice ability can be greatly enhanced.

Objective To investigate the effects of low frequency repetitive transcranial magnetic stimulation (rTMS) on non-fluent aphasia in patients after stroke.Methods Forty stroke patients displaying non-fluent aphasia were randomly assigned to an rTMS group and a control group using a random number table.Both groups were treated with conventional language therapy,while the rTMS group was additionally given 0.5 Hz rTMS over the Broca's homologues of the unaffected hemisphere 5 days a week for 3 weeks.The patients were stimulated at 90％ of the motor threshold (MT),with 16 second trains and intervals of 3 seconds 48 times (384 pulses) in a session.Before and after the 3 weeks of treatment,the Western Aphasia Battery (WAB) and the Communicative Abilities in Daily Living (CADL) test were conducted in both groups to evaluate their language function and communication ability.Results Only spontaneous speech improved significantly (P＜0.05) in the control group after 3 weeks of treatment.In the rTMS group,the spontaneous speech,auditory comprehension,repetition,naming and aphasia quotient (AQ) had all improved significantly (P＜0.05).Moreover,after the treatment,the average score of the auditory comprehension (153.90± 31.79),repetition (82.65± 15.14),naming(81.28±22.12) and AQ (63.66± 13.64) of the rTMS group were significantly higher than those of the control group (P＜0.05).Conclusion rTMS applied to the Broca's homologues of the unaffected hemisphere can significantly improve language function in those exhibiting non-fluent aphasia after stroke.

OBJECTIVETo determine if double bundle hamstring autograft posterior cruciate ligament (PCL) reconstruction could bring better outcomes than single bundle.

METHODSFrom June 2007 to June 2009, there were 22 subjects, including 16 male and 6 female patients with an average (37 ± 13) years old (16-54 years old) were reconstructed with single bundle PCL reconstruction (single bundle group), 24 subjects, including 18 male and 6 female patients with an average (37 ± 10) years old (17 - 52 years old) were reconstructed with double bundle PCL reconstruction (double bundle group). There were no differences between the two groups on patients' demographics and the duration from the injury to the operation (P > 0.05). Clinical outcomes, KT2000 and tunnel placements of all the patients were measured and analyzed.

RESULTSThe two groups were retrospectively studied and compared with a (29 ± 9) months (24 - 55 months) follow-up. Operation duration of double bundle group was (92 ± 8) minutes which was significantly longer than the single bundle group (78 ± 13) minutes (t = 2.474, P < 0.05). IKDC, Lysholm and Tegner scores were all significantly improved at the last follow-up of both groups (single bundle group: t = 9.578, 13.115 and 8.165, P < 0.01; double bundle group: t = 4.390, 5.522 and 4.313, P < 0.05). Post operative KT2000 side-to-side difference of the double bundle group was significantly smaller than that of the single bundle group under maximum posterior force with the knee in 90° flexion ((1.5 ± 1.5) mm vs. (4.0 ± 2.9) mm, t = 2.538, P = 0.019). There were 66.7% of the patients of double bundle group were normal which was significantly higher than 31.8% of the single bundle group on the IKDC knee examination form (χ² = 5.576, P = 0.018).

CONCLUSIONSSingle or double bundle PCL reconstruction could restore the knee's stability and function satisfied. There are no differences between two groups in clinical scores, but double group manifestes a better anterior-posterior stability.

Objective To explore the generalization and application of R-W1 through the phase analysis of Wave intensity technique.Methods The phases of R-W1 of 66 healthy adults were detected by Aloka Prosound α10 color Doppler uhrasound.Results There were all statistical significances in the time difference of R-W1 in left and right common carotid arteries and right brachial artery(P＜0.01),in the pressure wave conductive time in left and right common carotid arteries(P＜0.05),in right brachial artery and both sides of common carotid arteries(P＜0.01).There were no statistical significances in the time from the starting point to the culminate point of W1 in left and right common carotid arteries.There were statistical significances in the time from the starting point to the culminate point of W1 in right brachial artery and both sides of common carotid arteries(P＜0.05).Conclusions"R-W1 almost equals to pre-ejection period"as reported by literatures actually involves three phases which respectively are isovolumetric contraction time of left ventricle,pressure wave conductive time and time from the starting point to the culminate point of W1.The factor of pressure wave conductive time should be considered when evaluating diseases in clinic.The pre-ejection time should be the time from the culminate point of R wave in ECG to the starting point of W1 and the time from the starting point to the culminate point of W1 should not be involved in.

Infestation, moldy and other phenomenon in the processing and storage of Chinese herbal medicines is a problem that faced in the production of Chinese traditional medicine. The low productivity of traditional processing methods can not guarantee the quality of Chinese herbal medicines. Sulfur fumigation is the first choice of grassroots to process the Chinese herbal medicine with its low cost and easy operation. Sulfur fumigation can solve some problems in the processing and storage of Chinese herbal medicines, but modern pharmacological studies show that long-term use of Chinese traditional medicine which is fumigated by sulfur can cause some serious harm to human liver, kidney and other organs. This paper conducts a review about the application history of sulfur fumigation, its influence to the quality of Chinese herbal medicines as well as domestic and foreign limits to sulfur quantity, and a brief introduction of the status of modern processing technologies in the processing of food and some Chinese herbal medicines, the problems ex- isting in the Chinese herbal medicines processing, which can provide a reference basis for the further research, development and application of investigating alternative technologies of sulfur fumigation.
