Results showed that the infrared spectra of different broad bean diseased leaves were similar, which were mainly made up of the vibrational absorption bands of protein,lipid and polysaccharide.There were minor differences in-cluding the spectral peak position, peak shape and the absorption intensity in the range of 1 800-1 300 cm-1. There were obvious differences among their second derivative spectra in the range of 1 800-1 300 cm-1. After the procedure of the Fourier self-deconvolution and curve fitting of health bean leaves and broad bean diseased leaves in the range of 1 700-1 500 cm-1, three sub-peaks were obtained at 1 550 cm-1 （protein amide Ⅱ band）, 1 605 cm-1 （lignin） and 1 650 cm-1 （protein amide I band）.The ratios of relative areas of the bands of amide Ⅱ, lignin, and amide I were 38.86%, 28.68% and 32.47% in the spectra of healthy leaves, respec-tively. It was distinguished from the diseased leaves （chocolate spot leaf： 15.42%, 42.98% and 41.61%, ring spot leaf：32.39%, 35.63% and 31.98%, rust leaf： 13.97%, 46.40% and 39.65%, yel owing leaf curl disease leaf： 24.01%,36.55% and 39.44%）. For sub-peak area ratios （A1 563/A1 605, A1 650/A1 605 and A1 563/A1 654）, those of four kinds of diseased leaves were smal er than that of healthy leaves, and there were also differences among four kinds of diseased leaves. The results proved that FTIR combining with curve fitting might be a potential y useful tool for detecting different kinds of broad bean diseases.展开更多

In clinical practice, Neiguan (PC 6) is usually selected as one of the main acupoints to treat gastrointestinal reactions induced by ① nausea and vomiting, ② hiccup, ③ gastrointestinal dyskinesia, ④ gastritis, and ⑤ intra-gastric examination, cesarean section, etc. Concerning experimental studies, the effects of Neiguan (PC 6), etc. on ① gastric electrical activities, ② gastrointestinal motion, ③ gastrointestinal hormone secretion, and ④ gastric mucosal structure were observed. Results indicated that Neiguan (PC 6) is an important and effective acupoint for treatment of gastrointestinal disorders in clinic. Stimulation of Neiguan (PC 6) induced favorable regulation of both the peripheral nervous system and central nervous system, and changes of the gastrointestinal hormone secretion may contribute to its effects in treating various disorders.展开更多

The potentials of using Brassica juncea as green manure to kill the root lesion nematode Pratylenchus penetrans m soil and to decrease damages to subsequent crops were assessed in field and pot experiments. In the first trial, green manures containing B. juncea were grown and incorporated during spring to summer 2009. Japanese radish was then cultivated in each plot. In the second trial in spring 2010, green manure was grown and incorporated during summer to autumn 2009, and greater burdock was cultivated in pots containing soil sampled from each plot. Neither trial showed clear effects on nematode populations in the soil. However, in the first trial, Japanese radish grown following a B. juncea breeding line with a high content of sinigrin had a lower root lesion index and a higher number of marketable taproots than grown in the fallow soil. In the second trail, greater burdock cultivated in pots following incorporation ofB. juncea had a lower root lesion index with the incorporation of white mustard, which is widely used as a landscape plant. These findings suggest that B. juncea used as green manure can potentially decrease damage to subsequent crops caused by the root-lesion nematode, although it had no positive effect on decreasing populations of the root-lesion nematode in the soil.展开更多

Methods： A total of 74 patients were randomly divided into an EA group and a medication group based upon the random digital table, 37 cases in each group. EA at Zusanli（ST 36） and Fenglong（ST 40） was given in the EA group, once every day, for six treatments per week. Donepezil Hydrochloride Tablets were given to the medication group, 5 mg per time and once a day in the former four weeks, 10 mg per time and once a day after 4 weeks, oral administration before sleep at night. The courses of the treatment were 12 weeks in both groups. The scores of mini-mental state examination（MMSE） and Barthel index（BI） were observed before and after the treatment, for processing the comparative analysis of the clinical effects after the course of the treatment. Results： The total effective rate was 86.5% in the EA group and 70.3% in the medication group. The therapeutic effect was better in the EA group than that in the medication group, and the difference between the two groups was statistically significant（P〈0.05）. MMSE and BI scores after the treatment in the two groups were all elevated than those of the same groups before the treatment（P〈0.05, P〈0.01）. The improving situation was obviously better in the EA group than that in the medication group, and the difference between the two groups was statistically significant（P〈0.05）. Conclusion： EA at Zusanli（ST 36） and Fenglong（ST 40） is affirmative in the therapeutic effect for senile dementia and can also improve the cognitive function and enhance the patients＇ quality of life.展开更多

This herb has been consumed traditionally for the treatment of various diseases, including gastrointestinal disorders, respiratory disorders, infectious diseases, inflammatory diseases, as well as menstrual disorders. In the modern era, various pharmacological activities have been confirmed for M. longifolia, such as anti-parasitic, antimicrobial, anti-insect, antimutagenic, antinociceptive, anti-inflammatory, antioxidant, keratoprotective, hepatoprotective, anti-diarrhea, and spasmolytic effects. The plant showed therapeutic benefits in irritable bowel syndrome, amenorrhea and oligomenorrhea, and oxidative stress-associated diseases as well. A vast variety of natural components such as flavonoids, phenolic acids, cinnamates, ceramides, sesquiterpenes, terpenes, and terpenoids have been suggested to be responsible for the pharmacological action of M. longifolia. These natural products can be considered as novel medicinal sources for developing new drugs. Further investigations to explore therapeutic efficacy, tolerability,and pharmaceutical properties of M. longifolia phytochemical agents are recommended.展开更多

Multidrug resistance(MDR) is the main factor that leads to the failure of cancer chemotherapy. Thus, MDR diagnosis could facilitate the monitoring of the therapy process and realization of efficient treatment of tumors. In this study, we have tried to use a new tetrathiafulvalene(TTF) derivative(TTF-(COONBu4)2) to sensitively recognize the MDR through the multi-signal responsive strategy. The relevant electrochemical and spectroscopic studies demonstrate the specific binding behavior of TTF-(COONBu4)2 with P-glycoprotein(P-gp) as well as drug-resistant leukemia cells. Especially due to the over-expression of specific components of P-gp on the plasma membranes of drug resistant cells, the electrochemical and hydrophilic/hydrophobic features of drug resistant-leukemia cells are apparently different from those of other kinds of leukemia cells. Meanwhile, Fourier transform infrared spectroscopic study illustrates that the most intense vibration band of TTF moieties in the 1400–1600 cm-1 range is almost smeared out upon binding to P-gp, and the binding of TTF-(COONBu4)2 to P-gp may also lead to changes in protein secondary structure and backbone. This observation may advance the development of the new TTF agent for the promising clinical diagnosis and monitoring of MDR of tumors with the aim of successful chemotherapy for human cancer.展开更多
