Comparison on Rat Models of Acute Cerebral Infarction Due to Stasis Combined with Toxin Complicated with Cerebral-cardiac Syndrome / 中国实验方剂学杂志

ObjectiveTo observe and compare the electrocardiogram index， myocardial morphology， and connexin 43 （Cx43） expression of two rat models of acute cerebral infarction （ACI） due to stasis combined with toxin complicated with cerebral-cardiac syndrome （CCS）， and to provide experimental evidence for the research on the occurrence mechanism of cardiac diseases induced by ACI and the clinical diagnosis and treatment of CCS. MethodSixty SPF-grade male SD rats were randomized into six groups （n=10）： normal ， syndrome of stasis combined with toxin induced by carrageenin combined with dry yeast （CA/Y）， multi-infarct induced by micro-embolism （ME）， middle cerebral artery occlusion （MCAO）， CA/Y+ME， and CA/Y+MCAO groups. The model of syndrome of stasis combined with toxin was established by intraperitoneal injection with carrageenan （CA） at 10 mg·kg-1 on the first day and subcutaneous injection with dry yeast （Y） suspension （2 mg·kg-1） on the second day of modeling. Twenty-four hours after the modeling of ACI， the electrocardiograms （ECGs） of rats in each group were collected and the number/percentage （%） of abnormal ECG was calculated. The infarct area of the brain was evaluated by 2，3，5-triphenyltetrazolium chloride （TTC） staining， and myocardial injury was assessed by hematoxylin-eosin （HE） staining. Immumohistochemical staining and Western blot were employed to determine the expression of Cx43 in the myocardium. ResultA certain number of rats in each model group presented abnormal ECG. Compared with the normal group and CA/Y group， CA/Y+MCAO group had the highest rate of abnormal ECG （P<0.01）. Compared with the normal， CA/Y， ME， and CA/Y+ME groups， the CA/Y+ME and CA/Y+MCAO groups showed decreased amplitudes of P-wave and T-wave， shortened P-R interval， and extended Q-T interval， which were particularly obvious in the CA/Y+MCAO group （P<0.05， P<0.01） and in accordance with the cerebral infarction area and pathological changes. The expression of Cx43 was up-regulated in both CA/Y+ME and CA/Y+MCAO groups， especially in the CA/Y+MCAO group （P<0.01）. ConclusionThe two rat models of ACI due to stasis combined with toxin complicated with CCS can be used to study the mechanism of heart diseases caused by cerebrovascular diseases and the therapeutic effects of Chinese medicines with the functions of resolving stasis and detoxifying. Moreover， the CA/Y+MCAO method has higher abnormal electrocardiogram rate， severer myocardial pathological injury， and higher expression of Cx43 protein. The models can be chosen according to specific experimental purpose.

Establishment and Evaluation of Animal Models of Combined Stasis and Toxin Syndrome / 中国实验方剂学杂志

ObjectiveTo screen and establish animal models of combined stasis and toxin syndrome based on the comparison of three modeling methods， i.e.， carrageenan （Ca）， Ca combined with dried yeast （Ca+Yeast）， and Ca combined with lipopolysaccharide （Ca+LPS）. MethodForty SPF male SD rats were randomly divided into normal group， Ca group， Ca+Yeast group， and Ca+LPS group， with 10 rats in each group. The Ca group， Ca+Yeast group， and Ca+LPS group received an intraperitoneal injection of Ca （10 mg·kg-1） on the first day. The Ca+LPS group received an intraperitoneal injection of LPS （50 μg·kg-1） on the second day， and the Ca+Yeast group received a subcutaneous injection of dry yeast suspension （2 mg·kg-1） on the back on the second day. The rectal temperature of each group was dynamically observed after modeling. After 24 hours of modeling， the macroscopic evaluation indexes， including tongue manifestation， pulse， and black tail length in each group were observed. The PeriCam PSI imaging system was used to detect the blood flow perfusion of the rat tail. The automatic hemorheology analyzer was used to measure the whole blood viscosity and plasma viscosity of each group. The PL platelet function analyzer was used to detect the platelet aggregation rate of the rats. The enzyme-linked immunosorbent assay （ELISA） was used to detect the interleukin-6 （IL-6） level in the rat plasma. The myocardial tissue， brain tissue， and lung tissue of each group of rats were observed by hematoxylin-eosin （HE） staining. ResultCompared with the normal group， all three model groups showed varying degrees of black tail （P<0.05， P<0.01）， reduced blood flow perfusion at the tail end （P<0.05， P<0.01）， decreased R， G， and B values of tongue manifestation （P<0.05， P<0.01）， and increased maximum platelet aggregation rate （P<0.05， P<0.01）. The pulse amplitudes of the Ca+Yeast group and the Ca+LPS group were lower than that of the normal group （P<0.05， P<0.01）. In addition， the average rectal temperature of the Ca+Yeast group increased after 24 hours of modeling （P<0.01）， and the low-， medium-， and high-shear whole blood viscosity and plasma viscosity increased （P<0.05， P<0.01） as compared with those in the normal group. Additionally， the expression level of the plasma inflammatory factor IL-6 was significantly up-regulated （P<0.05）. Pathological morphology results showed that the Ca+Yeast group had the most severe pathological changes， with small foci of myocardial fiber dissolution， inflammatory cell infiltration， and fibroblast proliferation observed. In the hippocampal area， the neurons were sparse and had undergone red degeneration. In the small focus of the lung interstitium， lymphocytes and neutrophils were infiltrated. ConclusionThe animal model of combined stasis and toxin syndrome was properly established using Ca+Yeast. The systematic evaluation system of the model， which includes traditional Chinese medicine four diagnostic information， western medicine microscopic indicators， and tissue pathological morphology， is worthy of consideration and reference by researchers.

Diagnosis and Treatment of Traditional Chinese Medicine for Encephalopathy Based on the Theory of “Identificating the Onset of Diseases” / 中医杂志

Brain diseases in traditional Chinese medicine were complex and difficult to diagnosis and treatment， and new diagnostic and therapeutic ideas are urgently needed. The onset of the disease was the result of the struggle between healthy qi and pathogenic qi. Common types of the onset of diseases included sudden onset， slow onset， latent onset， secondary onset， and recurrent onset， reflecting the strength of the healthy qi and pathogenic qi， the pathogenic qi that reduced diseases， the site of onset， and other informatin. “Identificating the onset of diseases” was simple and easy to operate， and helped to clarify the complex development of encephalopathy. When applying it， we should first identify urgency and importance， focus on the characteristics； grasp the tendency of diseases， and know the overall situation of the disease； compare similarities and differences horizontally； and carefully observe and dynamically understand the disease. “Identificating the onset of diseases” has the characteristics of comprehensiveness and prognosis， and can lay the foundation for pattern identification and treatment and “treating disease before its onset”.

Development of Traditional Chinese Medicine in Serbia / 国际中医中药杂志

Serbia is a parliamentary republic country in Southeast Europe. It implements a health security system with social insurance as the mainstay and social assistance as a supplement. Ischemic heart disease, stroke and Alzheimer’s disease are the major causes of death, and the mortality rates of cardiomyopathy and chronic kidney disease are increasing. Serbia has relevant legislation on traditional medicine. Acupuncture, as the main form of Traditional Chinese Medicine (TCM), has been introduced to Serbia in an early stage. Acupuncture was recognized as a legal medical method in 2005, and then the corresponding educational institutions of TCM were established soon. However, the limitation of acupuncture treatment application, difficulty in access to Chinese medicine, and undeveloped of TCM education system, all of them restrict the development of TCM in Serbia. It is recommended to improve the development and dissemination of Chinese medicine in Serbia, like to increase the promotion of acupuncture, pay attention to the Chinese medicine for preventive health care, and strengthen TCM education.

Development of Traditional Chinese Medicine in Iraq / 国际中医中药杂志

Iraq is a multi-ethnic, multi-religious federal country located in southwest Asia and northeast of the Arabian Peninsula. Medical insurance is based on the primary health care model, supplemented by private medical care. Traditional medicine in Iraq is dominated by Islamic medicine. With the support of the Chinese government, the first Traditional Chinese Medicine (TCM) center was established in 2000. However, due to safety issues, the management of the center had problems such as insufficient staff, limited medical experience, and non-persistentsupport. At present, TCM has not been included in the Iraqi medical insurance system, which has affected the people’s medical choice and hindered the development of TCM. It is recommended to strengthen the construction of existing TCM centers, improve the accessibility of TCM education, and strengthen the cooperation and exchanges of traditional medicine between the two countries to promote the spread and development of TCM in Iraq.

Puerarin effects on the mRNA expression of osteoblast differentiation-related proteins / 中国组织工程研究

BACKGROUND:Experimental studies have showed that puerarin has an obvious protective effect on osteoporosis in ovariectomized and orchiectomized mice. But the influence of puerarin in the molecular level in the process of osteoblast differentiation is seldom reported. OBJECTIVE:To observe the effect of puerarin on the mRNA expression of alkaline phosphatase, bone sialoprotein, osteopontin and osteocalcin in osteoblasts. METHODS:The MC3T3-E1 cells from mice cultured in vitro were randomly divided into control group, puerarin group (10-6 mol/L puerarin) and estradiol group (10-7 mol/L estradiol) to observe the effects of puerarin on the differentiation of osteoblasts. mRNA expression of alkaline phosphatase, bone sialoprotein, osteopontin and osteocalcin in MC3T3-E1 cells was determined using RT-PCR method. RESULTS AND CONCLUSION:Puerarin and estradiol both could prolong the expression of alkaline phosphatase that reached the peak at 12 days. Puerarin and estradiol strengthened the mRNA expression of bone sialoprotein at 10 and 12 days, reduced expression of osteopontin at 5 and 12 days, and increased expression of osteocalcin at 10 and 12 days. These results reveal that puerarin can induce the differentiation of cultured osteoblasts by influencing osteoblast differentiation-related protein mRNA expressions, which may be one of the important molecular mechanisms of puerarin for prevention of osteoporosis.

Latent Structure Analysis and Syndrome Differentiation for Integration of Traditional Chinese Medicine and Western Medicine (III)：Establishment of Classification Rules / 世界科学技术-中医药现代化

Objective: In China, doctors at TCM hospitals and clinics often divide patients with a Western medicine (WM) disease into several syndrome classes from the TCM perspective and treat patients in different classes using different principles. A key problem is how to carry out the classification properly. We propose an evidence-based ap-proach for solving the problem where evidence is obtained by analyzing unlabeled symptom data using latent tree models.Method: In previous work, we have shown how latent tree analysis of symptom data can be used to identify TCM syndrome classes among patients with a WM disease. In the paper, we investigate how to establish classification rules for distinguishing between the classes.Results: We have applied the method to a data set about Vascular Mild Cognitive Impairment that involves 93 symptoms and 803 patients. Nine syndrome types are identified, along with the corresponding classification rules. Conclusions: An evidence-based approach to the TCM patient classification prob-lem has been developed. The approach can be used to answer the following questions about a WM disease: What TCM syndrome classes are there? What are the sizes of the classes? What are the statistical characteristics of each class? How can one differentiate between the different classes?

Objective To research the therapeutic effect of vitamin E in prevention and treatment of anemia in premature children.Methods We investigated 90 cases of premature children admitted to the neonatal ward of our hospital from December 2010 to December 2011.According to hospital successively order these premature were randomly divided into control group (Group A),high-dose group (Group B),low-dose group (Group A).Group A including 30 cases,subcutaneous injection of erythropoietin(EPO) from the 7th days after admission,750IU/kg weekly for 3 times,for 4 weeks.At the same time,plus iron 6mg/(kg·d).On the basis of the above-mentioned control treatment,oral administration of different doses of vitamin E was in the treatment group,for 4 weeks.Group B including 30 cases was given vitamin E 15mg/(kg·d).Group C including 30 cases was given vitamin E 2.5mg/(kg· d).The changes of each group during the treatment in hematocrit (Hct),hemoglobin(Hb),red blood cell(RBC),reticulocyte(Ret) and the changes of serum concentrations of vitamin E before and after treatment were observed.Results Hct,Hb,RBC,Ret in group B,group C patients were both improved.The improvement of the indicators was better than that of group A (P ＜ 0.05).There was no significant difference between the improvement of each index of Group B and Group C(P ＞ 0.05).Serum concentrations of vitamin E after treatment in group B and group C patients were significantly higher and the difference was statistically significant(P ＜ 0.05).Serum concentration of vitamin E in group A didn't increase obviously.Conclusion Additional small doses of VitE should be given during EPO prevention of anemia in premature children.

Stydy on the changes of intraocular pressure in obstructive sleep apnea syndrome / 中国综合临床

Objective To compare the changes of intraocular pressure (IOP) in 24 hours between obstructive sleep apnea syndrome(OSAS) and the non-obstructive sleep apnea syndrome(non-OSAS).Methods Sixty patients with OSAS were divided into two groups:OSAS group(n =30) and non-OSAS group (n =30).The following indicators were detected:(1) Awake oxygen saturation ((HSaO2) ％),(2) The lowest oxygen saturation (LSaO2) ％) ; (3) Mean oxygen saturation ((MSaO2 ％)) ; (4) Oxygen desaturation index ((DI4),time/h:number of times that the hourly oxygen desaturation ≥ 4％) ; (5) The percentage of the time that oxygen saturation ≤ 90％ accounts the total time ((SIT90)％) and 24-hour IOP.IOP was measured from early morning 5:00 and measured once every four hours.The measurement results were compared between two groups.Results There was no significant difference on age ((62.60 ± 12.44) years old vs (65.20 ± 10.66)years old,t =1.48),Course of disease ((22.40 ± 6.88) month vs (25.49 ± 7.22) month,t =1.97),gender (The ratio of male to female is(20/10)vs (17/13),x2 =0.007) between the OSAS and the non-OSAS(P ＞0.05).Value of AHI(h-1) ((27.9 ±6.0) vs (2.5 ±1.1),t =8.78),LSaO2 ((74.7 ±11.7)％ vs (91.8 ±5.9)％,t=3.44),SIT90((13.2±12.4)％ vs(0.2±1.1)％,t=9.92) and ODI4(h-1) ((28.9 ±13.9)vs (6.1 ±4.1),t =8.09) of OSAS was significantly higher than that of non-OSAS(P ＜0.05 or P ＜0.01).Value of IOP of 21:00 o'clock((20.61±4.15)mm Hg vs(19.60 ± 4.03)mm Hg,t =2.18),1:00 o'clock((23.12 ±3.11)mm Hg vs (20.60 ± 3.29) mm Hg,t =4.64) and 5:00 o' clock ((22.82 ± 2.99)mm Hg vs (17.21 ±3.55) mm Hg,t =4.23) of OSAS was significantly higher than that of non-OSAS (P ＜ 0.05 or P ＜ 0.01).The wave ((10.40 ± 2.85)mm Hg vs (8.40 ± 2.55) mm Hg,t =4.15) and maximal ((23.60 ± 3.29) mm Hg vs (21.23 ±3.43)mm-Hg,t =2.60) value of IOP of OSAS was significantly higher than that of non-OSAS(P ＜0.05 or P ＜0.01).There was no significant difference on minimum of IOP between the OSAS and the non-OSAS ((13.20 ± 4.08)mm Hg vs (12.70 ± 4.22) mm Hg,t =0.54,P ＞ 0.05).Conclusion There are higher wave and maximal value of IOP in the patients of OSAS during the night.It is important to pay attention to IOP in order to protect those patients' visual function.
