ABSTRACT
ObjectiveTo explore the possible mechanism of Yupingfeng Granules （玉屏风散） in preventing and treating chronic obstructive pulmonary disease （COPD） from the perspective of “lung-gut axis”. MethodsThirty-two male Wistar rats were randomly divided into normal group，model group， roxithromycin group and Yupingfeng Granules group， with 8 rats in each group. Except for the normal group， the rat model of COPD was prepared by intratracheal instillation of lipopolysaccharide （LPS） combined with smoking for 12 weeks. Since the fifth week of modeling，the roxithromycin group and the Yupingfeng Granules group were given 31.5 mg/（kg·d） and 1.575 g/（kg·d） of corresponding drugs respectively by gavage，and normal group and model group were given 10 ml/（kg·d） physiolo-gical saline. Sample was collected 24 hours after the last administration. The pathological changes of lung tissue were observed using HE staining； Ultrahigh performance liquid chromatography quadrupole time of flight mass spectrometry （UHPLC-QTOFMS） was used to detect the differential metabolites in alveolar lavage fluid （BALF） in all groups but roxithromycin group；16S rDNA sequencing technology was used to detect the changes of intestinal flora， and the association analysis was conducted between the differential metabolites and the differential flora. ResultsCompared with the normal group， the model group showed an increase in goblet cells in the small bronchial wall， disappearance of the smooth muscle layer of the bronchial wall， and infiltration of inflammatory cells； compared with the model group， roxithromycin group showed slight alveolar interstital edema， and obviously reduced inflammatory cell， while no obvious alveolar interstital edema was observed in the Yupingfeng Granules group， showing a small amout of inflammatory cell infiltration. The results of the BALF differential metabolite screening showed that compared with the normal group， 12 substances were upregulated and 19 substances were downregulated in the model group； compared with the model group， 37 substances in the Yupingfeng Granules group were upregulated and 43 substances were downregulated KEGG analysis yielded a total of 2 metabolic pathways， glycerophospholipid metabolism， and unsaturated fatty acid biosynthetic metabolism； compared with the model group， choline， acetylcholine， glycerol-3-phosphate， glycerophosphate choline， palmitic acid， and arachidonic acid showed an upward trend， while stearic acid and docosahexaenoic acid showed a downward trend in Yupingfeng Granules group （P＜0.05）. The results of the intestinal flora showed that， there are 80 different species between the normal group and the model group， and 65 different species between the model group and Yupingfeng Granules group. Among the top 5 species with relative abundance levels，compared with the model group， the level of Prevotella_9，Ruminococcaceae_UCG-005，Ruminiclostridium_6 increase，and Lactobacillus，Bacteroides decrease（P＜0.05）.The results of the correlation analysis showed that， in the normal and model groups， arachidonic acid was negatively correlated with Oribacterium（r=-0.753，P＜0.01）； in the Yupingfeng Granules group and model group， stearic acid and Bacteroides（r=0.788）， Mycobacterium（r=0.826），［Eubacterium］_Ruminantium_Group（r=0.770） was positively correlated（P＜0.01）， Arachidic acid was negatively correlated with Roseiarcus（r=-0.779）， glycerol-3-phosphate was negatively correlated with Desulfovibrio（r=-0.758）， Arachidonic acid was negatively correlated with Oribacterium（r=-0.753）， and Palmitic acid was negatively correlated with Pseudolabs（r=-0.750，P＜0.01）. ConclusionYupingfeng Granules can affect the metabolism of BALF and the flora structure of intestinal microorganisms， and regulating the balance of “lung-gut axis” may be one of the mechanisms of Yupingfeng Granules in treatment of COPD.
ABSTRACT
Objective:To establish an optimized automatic synthesis method of 18F-fallypride, and evaluate its biodistribution and microPET/CT characteristics. Methods:18F-fallypride was automatically prepared by AIO synthesis module and disposable cassette & reagents kit. The crude product was purified by a dedicated coupled column (HLB+ Alumin-N) to obtain the final product. Radiochemical purity and radiolabeling yield were determined. Parkinson′s disease (PD) model mice and rats were established. The radioactive distribution of different organs of PD model mice ( n=24) were monitored. The distribution process of the agent in the SD rat brain (PD model, n=6; normal rat, n=6) were evaluated by microPET/CT imaging. Results:The radiochemical yield of 18F-fallypride synthesized by automatic synthesis module was stable at (10±1)% ( n=5, no decay corrected). The total synthesis time was about 40 min. The radiochemical purity of 18F-fallypride was more than 95%, and the radiochemical purities were also over 95% after being stored in saline and serum for 120 min at room temperature. 18F-fallypride was mainly excreted by the kidneys, and it was less radioactive intake in the liver and spleen in PD mice. MicroPET/CT imaging showed that higher accumulation of 18F-fallypride was noted in corpus striatum and the SUV ratio of PD group was lower than that of control group (5.00±0.93 vs 6.53±1.96). Conclusion:18F-fallypride can be successfully prepared automatically by improved multifunctional module, with the advantages of convenient preparation, stable radiochemical yield, satisfying purity and quality control, so it can be used in the follow-up standardized production of Good Manufacture Practice (GMP) system.
ABSTRACT
Objective: To observe the effects of electroacupuncture (EA) with three frequencies (100 Hz, 2 Hz, and 2 Hz/100 Hz) on the apoptosis of neurons and c-Jun N-terminal kinase (JNK) signaling pathway in the hippocampus of rats with vascular dementia (VD), and explore the mechanism of EA intervention for VD. Methods: Fifty male Sprague-Dawley rats were randomly divided into a model group, a sham operation group, a 100 Hz EA group, a 2 Hz EA group, and a 2 Hz/100 Hz EA group, with ten rats in each group. The VD model rats were established by repeated ischemia-reperfusion of bilateral common carotid arteries. The rats in the EA groups received EA intervention at Baihui (GV20), Dazhui (GV14), Geshu (BL17) and Zusanli (ST36), once a day for 14 d. Afterward, Morris water maze was used to examine the learning and memory performances of the rats in each group, hematoxylin-eosin staining to observe the histomorphological changes in the hippocampal CA1 region, terminal deoxynucleotidyl transferase-mediated dUTP nick end labeling to test the apoptosis of neurons in the hippocampal CA1 region, and Western blot to detect the protein expression levels of JNK, phosphorylated JNK (p-JNK), Caspase-8, and Caspase-3 in the hippocampus tissue. Results: Compared with the sham operation group, the escape latency of the model group in water maze test was prolonged; the number of crossing the original platform was decreased (P<0.01); the hippocampal neurons were severely damaged and the number of surviving neurons was decreased (P<0.01), whereas the number of apoptotic neurons was increased (P<0.01); the protein expression levels of JNK, p-JNK, Caspase-8, and Caspase-3 in the hippocampus were significantly increased (P<0.01). Compared with the model group, the escape latency of each EA group was significantly shortened; the number of crossing the original platform was significantly increased (P<0.01); the damage of hippocampal neurons was alleviated, the number of surviving neurons was increased (P<0.01), and the number of apoptotic neurons was decreased (P<0.01); the protein expression levels of JNK, p-JNK, Caspase-8, and Caspase-3 in the hippocampus were decreased (P<0.01). The results in the 2 Hz EA group and the 2 Hz/100 Hz EA group were superior to those in the 100 Hz EA group. Conclusion: EA with the three frequencies (100 Hz, 2 Hz, and 2 Hz/100 Hz) can improve the learning and memory performances in VD rats subjected to ischemia-reperfusion, its mechanism may be related to the inhibition of neuronal apoptosis and the regulation of the related protein expression of JNK signaling pathway, and the intervention effects of EA with 2 Hz and 2 Hz/100 Hz are more significant.
ABSTRACT
Autophagy is a process of degrading the damaged organelles and macromolecules by lysosomes in cells, which belongs to the programmed cell death. Cerebral ischemia is one of the important reasons for activation of autophagy. Studies have showed that autophagy plays a protective role in neuronal death induced by ischemia. However, it has also been found that excessive activation of autophagy could aggravate cerebral ischemia injury. In recent years, more and more Chinese medicine has been proved to regulate the autophagy level of brain neurons and reduce cerebral ischemia injury. In this paper, the main molecular mechanism of autophagy in the process of cerebral ischemic injury and the intervention effects of Chinese herbs on autophagy arereviewed in order to explore the basic principle of regulating autophagy by Chinese herbs and to play a better role in the clinical treatment of cerebral ischemic diseases.

ABSTRACT
Objective@#To analyze the average systolic blood pressure (SBP) and diastolic blood pressure (DBP) among adults aged 18 years old and above in China between 2010 and 2012; and to compare the difference in the results measured by mercury sphygmomanometer and converted electronic sphygmomanometer.@*Methods@#The data was collected from Chinese Nutrition and Health Surveillance in 2010-2012. 120 428 adults aged 18 years old and above were selected from 150 survey counties (districts) of 31 provinces in China Mainland, by multi-stage stratified and probability proportion to size (PPS) cluster randomization sampling method. The average blood pressure value was calculated from three systolic and diastolic blood pressure readings measured by mercury sphygmomanometer. The value of Electronic Sphygmomanometer was converted by regression formula. Age-standardized results were calculated incorporating a complex sample weighting using the population data from the National Bureau of Statistics in 2009.@*Results@#The overall adjusted mean of SBP based on the value of mercury sphygmomanometer among Chinese adults aged 18 years old and above was 122 mmHg (1 mmHg=0.133 kPa), 124 mmHg in men and 120 mmHg in women. The average SBP value was separately 115, 127, and 137 mmHg in groups of adults aging 18-44, 45-59 and ≥60 years old. The average SBP was 122 mmHg in urban and 122 mmHg in rural areas. Mean DBP was 78 mmHg, 79 mmHg in men and 76 mmHg in women. The average DBP was separately 75, 81, and 81 mmHg in groups of adults aging 18-44, 45-59 and ≥60 years old. The average DBP was 78 mmHg in urban and 77 mmHg in rural areas. The overall adjusted mean of SBP based on converted electronic device was 129 mmHg,130 mmHg in men and 127 mmHg in women, respectively. The mean of SBP was separately122, 134, and 143 mmHg in groups of adults aging 18-44, 45-59 and ≥60 years old. Mean SBP was both 129 mmHg in urban and in rural areas. Mean DBP was 76 mmHg, 78 mmHg in men and 75 mmHg in women, respectively. The average DBP was separately 74, 79, and 79 mmHg in groups of adults aging 18-44, 45-59 and ≥60 years old. The average DBP was both 76 mmHg in urban and rural areas.@*Conclusion@#The average SBP and DBP was different between the mercury sphygmomanometer and converted electronic device. However, the results from both measures showed that the blood pressure was higher in men than in women, the blood pressure increased with the increase of age, and there was no difference between urban and rural areas.

The average consumption of vegetables or fruits after weight adjustment for complex sampling was reported to analyze the consumption of fruits and vegetables of Chinese adults (x ± Sx).</p><p><b>RESULTS</b>The average daily consumptions of vegetables and fruits for Chinese residents were (255 ± 6) and (36 ± 3)g/d, respectively. The total consumptions of fruits and vegetables were (291 ± 7)g/d, (295 ± 8)g/d for male, (286 ± 7)g/d for female. Rates on intake of vegetables in Chinese adults during the three survey days were 99.0%-99.8%.Rates on intake of fruits of urban and rural residents were 36.9%-51.5% and 21.3%-30.3%,respectively.The proportion of people whose total amount of vegetables and fruits intake reached 400 g/d were 24%-28% and 13%-23% in urban and rural areas, respectively. In urban and rural areas, the proportion of adults whose consumption reached Chinese dietary guidelines recommended level were 22%-26% and 14%-19% in vegetables, 2%-5% and 1%-2% in fruit, respectively.</p><p><b>CONCLUSION</b>The consumptions of vegetables and fruits were inadequate in Chinese adults.</p>

Objective To observe effect of Kechuanning on the expression of IL-5mRNA in lung tissue of bronchial asthmatic rats.Methods Forty rats were randomly divided into 5 groups:the normal group,the model group,Kechuanning high-dose group (27 g/kg),Kechuanning low-dose group (13.5 g/kg),Guilong Kechuanning control group (0.45 g/kg),8 rats in each group.The bronchial asthmatic model was established by egg protein sensibilization and inhalation provocation.The rats of each treatment group were lavage administration each day from the first time of provocation to execution.After 4 weeks of treatment,the rats were killed and lung tissue were taken to dying of HE to be observed.The expression of IL-5mRNA in lung tissue were determined by RT-PCR.Result Compared with the normal group,the thickness of bronchus wall and bronchus smooth muscle,the numbers of eosinophile granulocyte and leukomonocyte,and expression of IL-5mRNA in lung tissue were increased (P
ABSTRACT
Objective: To observe effect of Kechuanning on expression of nuclear factor kB(NF-?B) in lung tissue of bronchial asthmatic rats.Methods: 40 rats were randomly divided into 5 groups: the normal group,the model group,Kechuanning high-dose group(27g/kg),Kechuanning low-dose group(13.5g/kg),GuilongKechuanning control group(0.45g/kg),8 rats in each group.The bronchial asthmatic model was established by egg protein sensibilization and long-term inhalation provocation.The rats of each treatment groups were lavage administration each day from the first time of provocation to execution.After 4 weeks of treatment,the rats were killed and lung tissue were taken to dyeing of HE to be observed.The expression of NF-?B in lung tissue were determined by immunohistochemistry.Result: Compared with the normal group,the thickness of bronchus wall and bronchus smooth muscle,the numbers of eosinophile granulocyte and leukomonocyte,and expression of NF-?B in lung tissue were increased in the model group(P
ABSTRACT
Objective: To observe the effect of traditional Chinese medicine Jiusuyu(酒速愈) on activities of superoxide dismutase(SOD) and catalase(CAT),as well as the content of malondialdehyde(MDA) in liver tissues of mice with acute alcoholism.Methods: The models of acute alcoholism mice were established by drinking 56% Hongxing Erguotou(红星二锅头) drink.Eighty healthy Kunming mice were randomly divided(into) normal group,model group,high Jiusuyu dosage group,low Jiusuyiu dosage group and Gehua Jiecheng decoction(葛花解酲汤) group,with 16 animals in each group.The SOD,CAT activities and the content of MDA in(liver) tissues of each group were detected 6 hours after treatment.Results: The content of MDA in(liver) tissues of the model group was increased(P
