RESUMEN
ObjectiveThe law of fertilizer requirement serves as the basis for the fertilization of medicinal plants, development of special fertilizer, and high-quality medicinal materials. MethodThis study aims to explore the optimal potassium application rate for Panax ginseng to achieve high yield and quality of the medicinal material and targeted management of potassium fertilizer. To be specific, 6 concentration gradients (0, 2, 4, 8, 10, and 12 mmol·L-1) of potassium sulfate (potassium fertilizer) were designed and applied to the 4-year-old P. ginseng in CK, C1, C2, C3, C4, and C5 treatments, respectively. Thereby, the influence of potassium concentration on P. ginseng was observed. ResultWhen potassium sulfate was applied at 8 mmol·L-1, P. ginseng had the chlorophyll content of 32.13%, net photosynthetic rate of 2.548 8 µmol·m-2·s-1, and activities of superoxide dismutase (SOD), peroxidase (POD), and catalase (CAT) significantly higher than those in the CK, C1, C4, and C5 treatments (P<0.05). The average fresh weight of P. ginseng roots was 6.25 g, 134% up from the CK, and the content of ginsenoside Rg1 (5.24 mg·g-1) and Re (4.17 mg·g-1) and total saponins (12.33 mg·g-1) was significantly higher than that in CK and other treatments (P<0.05). Thus, 8 mmol·L-1 potassium sulfate was most favorable for the growth and effective component accumulation of four-year-old P. ginseng. ConclusionThis study expounds the effect of potassium fertilizer on the yield and quality of P. ginseng, which is expected to help guide the precise application of potassium fertilizer in P. ginseng production in the field and lay a theoretical basis for the development of special fertilizer for P. ginseng and the optimization of fertilization technology.
RESUMEN
The sustainable use of medicinal plants is the foundation of the inheritance of traditional Chinese medicine(TCM) and the acquisition of information on medicinal plants is the basis for the development of TCM. The traditional methods of investigating medicinal plant resources are disadvantageous in strong subjectivity and poor timeliness, making it difficult to real-time monitor medicinal plant resources. In recent years, remote sensing technology has become an important means of obtaining information on medicinal plants. The application of this technology has made up for the shortcomings of traditional methods. The open-access remote sensing data with medium spatial resolution satellites provide an opportunity for extracting information on medicinal plant resources. This study firstly introduced the principles of remote sensing technology, summarized the satellites and the parameters commonly used in the field of medicinal plant resources, and compared the survey methods of remote sensing technology with traditional methods. Secondly, it reviewed the applications of remote sensing technology in the extraction of information on the cultivation of medicinal plants and the common methods for extracting the planting structure information of medicinal plants based on remote sensing technology. Thirdly, the applications of remote sensing technology in the investigation and monitoring of medicinal plants were further analyzed with the research objects divided into wild and cultivated medicinal plants according to the characteristics of the habitats. Finally, it pointed out the key unsolved technical problems in the remote sensing monitoring of medicinal plant resources, and proposed solutions for the intelligent information processing of medicinal plants based on remote sensing big data, which is expected to provide references for the development of remote sensing technology in derivative application in medicinal plant resources.

Liver injury remains a significant global health problem and has a variety of causes, including oxidative stress (OS), inflammation, and apoptosis of liver cells. There is currently no curative therapy for this disorder. Sanwei Ganjiang Prescription (SWGJP), derived from traditional Chinese medicine (TCM), has shown its effectiveness in long-term liver damage therapy, although the underlying molecular mechanisms are still not fully understood. To explore the underlining mechanisms of action for SWGJP in liver injury from a holistic view, in the present study, a systems pharmacology approach was developed, which involved drug target identification and multilevel data integration analysis. Using a comprehensive systems approach, we identified 43 candidate compounds in SWGJP and 408 corresponding potential targets. We further deciphered the mechanisms of SWGJP in treating liver injury, including compound-target network analysis, target-function network analysis, and integrated pathways analysis. We deduced that SWGJP may protect hepatocytes through several functional modules involved in liver injury integrated-pathway, such as Nrf2-dependent anti-oxidative stress module. Notably, systems pharmacology provides an alternative way to investigate the complex action mode of TCM.

<p><b>OBJECTIVE</b>To observe effects of treatment from the lung and treatment from the intestine on the level of vasoactive intestinal peptide (VIP) in the lung and intestine of ulcerative colitis (UC) rats.</p><p><b>METHODS</b>The UC rat model was established in 52 rats by using rabbit intestine mucosa tissue allergen combined TNBS-ethanol model (with the model successful rate of 78.0%). Eight rats randomly selected from 40 successfully modeled rats and 8 of 16 rats from the normal group were recruited as the model group and the normal control group before intervention (at week 0). The rest 32 successfully modeled rats were randomly divided into the model group, the Western medicine treatment group (salazosulfapyridine), the treatment from lung group (Huangqi Jiegeng Decoction), and the treatment from intestine group (Huangqi Huanglian Decoction), 8 in each group. Rats in each treatment group were administered with corresponding medication 8 times the dose of a 60 kg adult human. Another 8 normal rats were recruited as the normal group. Equal volume of pure water was given to rats in the model group and the normal group by gastrog avage, once per day. Contents of VIP in the lung tissue and the intestinal tissue were detected at week 0 and 4 after 4-week consecutive intervention. Pathomorphological changes of the lung tissue and the colon tissue were observed under light microscope.</p><p><b>RESULTS</b>Compared with the normal control group at week 0, evenly distributed diffuse inflammation could be seen in the pulmonary interstitial tissue; the bronchial wall was thickened; a huge amount of infiltration surrounded bronchi and blood vessels; a large area of necrosis of intestinal mucosa and inflammatory cell infiltration could also be seen in the model group. Pathological injuries of the lung and the colon were more alleviated in each treatment group than in the model group at the same time point. Compared with the normal control group at the same time point, VIP contents in the lung tissue significantly decreased in the model group at the end of week 4 (P<0.05); VIP contents in the colon tissue significantly increased in the model group at the end of week 0 and 4 (P <0.05). Compared with the model group, VIP contents in the lung tissue significantly increased in the Western medicine treatment group and the treatment from lung group at the end of week 4 (P<0.01); VIP contents in the colon tissue significantly decreased in the treatment from lung group and the treatment from intestine group (P<0.05, P<0.01).</p><p><b>CONCLUSION</b>Treatment from the lung and treatment from the intestine showed predominant advantage in improving local inflammation of the lung and the intestinal tract, alleviating pathological injuries, promoting repair of injuries through regulating VIP contents in the lung tissue and the colon tissue.</p>

<p><b>OBJECTIVE</b>To explore Chinese medical theory of Fei and Dachang being interior-exteriorly correlated by observing changes of inherent immune response and acquired immune response in the lung tissue and the intestinal tissue of ulcerative colitis (UC) model rats and the intervention of Chinese compounds (CM).</p><p><b>METHODS</b>Seventy rats were randomly divided into 5 groups, i.e., the normal control group (n = 10), the model group (n = 15), the treatment 1 group (n = 15, treated from Fei), the treatment 2 group (n = 15, treated from the intestine), and the Western medicine (WM) group [n = 15, treated with Sulfasalazine (SASP). Except those in the normal control group, the UC rat model was prepared by allergizing colon mucosa combined with TNBS-alcohol (50%) enema, and then intervened by medication (treated with CM complex prescription of treatment from lung, CM complex prescription of treatment from intestine, and SASP). After intragastric administration for 4 weeks, rats were sacrificed and samples taken. The expression of tumor necrosis factor α (TNF-α) and IL-8 contents in the lung tissue, the intestinal tissue, and the serum were detected by radioimmunoassay. Serum MedCAM-1 contents were detected using ELISA. Changes of the expression of Toll-like receptor 4 (TLR4), nuclear factor κB (NF-κB), neutrophil migration inhibition factor (MIF), mucosal addressin cell adhesion molecule-1 (MadCAM-1) mRNA in the lung tissue and the intestinal tissue were detected by real time PCR.</p><p><b>RESULTS</b>Compared with the normal control group, the expression levels of TNF-α, TLR4 mRNA, IL-8, MIF mR- NA, and MadCAM-1 mRNA obviously increased in the model group (P < 0.01). Compared with the model group, the expression levels of TNF-α, TLR4 mRNA, IL-8, MIF mRNA, and MadCAM-1 mRNA obviously decreased in the treatment 1 and 2 groups (P < 0.01). The expression of MadCAM-1 mRNA in the intestinal tissue was obviously higher in the model group than in the normal control group (P < 0.01), while the expressions of TNF-α and NF-κB mRNA was obviously lower in the model group than in the normal control group (P < 0.05, P < 0.01). Compared with the model group, the expression of MadCAM-1 mRNA all significantly deceased in each treatment group (P < 0.05, P < 0.01). Serum TNF-α contents were higher in the model group than in the normal control group (P < 0.05). Compared with the model group, serum TNF-α contents could be lowered in the treatment 1 and 2 groups (P < 0.05, P < 0.01).</p><p><b>CONCLUSIONS</b>The main mechanisms of the intestinal injury in this UC model might be related with activation of acquired immune response, accompanied with lowered functions of inherent immune response. The main mechanisms of the lung injury in this UC model might be related acquired immune response and inherent immune response. Treatment from Fei and treatment from Dachang both could obviously improve the immunodissonance of Fei and Dachang, indicating the special relation between the lung tissue and the intestinal tissue, thus providing experimental evidence for Chinese medical theory of Fei and Dachang being interior-exteriorly correlated.</p>

Ulcerative colitis (UC), a kind of chronic nonspecific intestinal inflammation with unknown etiology, is very difficult to cure. It recurs often and even is accompanied with parenteral lesion. It has been rated as one of contemporary refractory diseases by World Health Organization. The author combines the pathological mechanisms of UC with the poison-evil theory and the collateral disease theory, and puts forward that "toxin impairing intestine collateral" pathogenesis theory. We believe that longer accumulation of damp-heat stasis toxin that damages the intestine collateral is the key cause for recurrence and relapses of UC. We explained its theory foundation in terms of pathogenesis of UC from Chinese medicine and modern medicine. The "toxin impairing intestine collateral" theory might perfect the syndrome typing system for UC, and provide a new way of thinking for treating UC.

<p><b>OBJECTIVE</b>To observe the features of bronchopulmonary lesions in ulcerative colitis (UC) rats and the specificity with Fei and Dachang, thus providing reliance for the theory of "intestinal diseases involved Fei".</p><p><b>METHODS</b>The UC rat model was duplicated by using rabbit intestine mucosa tissue allergenic model and TNBS-ethanol model. A normal rat group was set up as the control. The pulmonary functions [including inspiratory resistance (Ri), expiratory resistance (Re), forced vital capacity (FVC); FEV. 2/FVC, maximal voluntary ventilation (MVV), forced expiratory flow rate (FEF25% - 75%)], and indicators of liver and kidney functions [serum alanine aminotransferase (ALT), aspartate amino transferase (AST), blood urea nitrogen (BUN), and creatinine (Cr)] were detected in the two groups. The pathological changes of colon, lung, liver, and kidney were observed in the two groups.</p><p><b>RESULTS</b>Rats in the model group in both acute and chronic stages had weight loss, mucus and loose stool. Partial rats had such symptoms as dyspnea, shortness of breath, and wheezing. Compared with the normal group, the MW, FVC, FEV0.2 and FEF25% -75% in the acute stage; Ri, Re, MVV, FVC, and FEF25% - 75% in the chronic stage all significantly decreased (P <0.05, P <0.01), and FEV0.2/FVC significantly increased in the model group (P <0.05). The pathological results showed interstitial pneumonia and pulmonary interstitial fibrosis in the model group. But the indicators of liver and kidney functions were all in the normal range. No obvious pathological change was seen in the renal and liver tissues in the two groups.</p><p><b>CONCLUSIONS</b>UC could specifically induce bronchopulmonary lesions. Lung injury was one of UC's intestinal manifestations. The theory of "Fei and Dachang being interior-exteriorly correlated" was demonstrated from the theory of "intestinal diseases involved Fei".</p>

<p><b>OBJECTIVE</b>To observe the effects of Huangqi Jiegeng Decoction (HJD) and Huangqi Huanglian Decoction (HHD) on the intercellular adhesion molecule-I (ICAM-1) content in the lung and colon of rats with Crohn's disease (CD).</p><p><b>METHODS</b>Totally 56 rats were used to establish the CD rat model using TNBS water solution/absolute alcohol enema (with the model successful rate of 63.0%). Seven rats randomly selected from 35 successfully modeled rats and from the normal group were recruited as the model group and the normal group before intervention. The rest 28 successfully modeled rats were randomly divided into the model group, the Western medicine group (treated with salazosulfapyridine at 0.4 g/kg), the HJD group (20.5 g/kg), and the HHD group (20.8 g/kg), 7 in each group. Another 7 normal rats were recruited as the normal group. Equal volume of pure water was given to rats in the normal group and the model group by gastrogavage, twice daily, for 3 successive weeks. The protein and mRNA expressions of ICAM-1 in the lung and colon tissues were determined before and after intervention using Western blot and RT-PCR.</p><p><b>RESULTS</b>Compared with the normal control group, the protein and mRNA levels of ICAM-1 in the colon tissue, and the mRNA level of ICAM-1 in the lung tissue increased (P< 0.01, P<0.05). After intervention the protein and mRNA levels of ICAM-1 in the colon tissue and the lung tissue increased (P<0.01) in the model group. Compared with the model group at the same time point, the protein and mRNA levels of ICAM-1 in the colon tissue and the lung tissue decreased in each medication group after intervention (P<0.01, P<0.05). Compared with the Western medicine group, the protein level of ICAM-1 in the lung tissue decreased more significantly in the HJD group (P<0.05). The protein level of ICAM-1 in the colon tissue also decreased in the HHD group (P<0.05).</p><p><b>CONCLUSIONS</b>HHD and HJD both could down-regulate the over-expressed ICAM-1 in the lung and colon tissues of CD rats. HHD was prominent in inhibiting the adherence of colonic inflammatory cells and attenuating local immunopathological injury. HJD was prominent in attenuating inflammation and injury in the lung, and preventing pulmonary fibrosis.</p>

<p><b>OBJECTIVE</b>To study the correlation between the pulmonary injury and the ET-1 serum level in ulcerative colitis (UC) patients, and to study the mechanism for UC induced pulmonary injury.</p><p><b>METHODS</b>Recruited were 90 UC outpatients from the clinics of Gastroenterology Department, Dongzhimen Hospital Affiliated to Beijing University of Chinese Medicine from Nov. 2009 to Mar. 2011. The course of disease, disease range, serum ET-1 level of UC patients were observed and compared. The correlation between the serum ET-1 level and each pulmonary function index were studied [including vital capacity (VC), forced vital capacity (FVC), forced expiratory volume in one second (FEV1), FEV1/FVC, peak expiratory flow (PEF), maximal mid expiratory flow (MMEF), maximal expiratory flow in 25%, 50%, 75% vital capacity (FEF25%, 50%, 75%), diffusion capacity for carbon monoxide of lung (DLCO), diffusion constant (KCO), total lung capacity (TLC), alveolar ventilation (VA), residual volume (RV), function residual volume (FRV), and RV/TLC]. Besides, another 30 healthy volunteers were enrolled as the control group. The pulmonary symptoms, chest X-ray, the lung function, the serum ET-1 level, and liver and kidney functions [including alanine aminotransferase (ALT), aspartate aminotransferase (AST), blood urea nitrogen (BUN), serum creatinine (SCr) were compared between the UC group and the control group.</p><p><b>RESULTS</b>Ten UC patients were accompanied with cough and chest distress (accounting for 11.1%), 25 with abnormal chest films (accounting for 27.8%), and 54 with pulmonary function abnormality (accounting for 60.0%). In the UC group ALT increased in 2 cases (2.2%) and AST increased in 2. They were normal in the control group. The BUN and SCr were normal in the two groups. Compared with the control group, the serum ET-1 level in the UC group was significantly higher than that in the control group (P < 0.05). There was no statistical difference in the serum ET-1 level (P > 0.05). There was statistical difference in the serum ET-1 level in the UC group between those with the disease course > or = 5 years and those with the disease course <5 years, showing statistical difference (P < 0.05). There was negative correlation between the serum ET-1 level and FEF25% and between the serum ET-1 level and KCO (P < 0.05).</p><p><b>CONCLUSIONS</b>Serum ET-1 level could reflect the pulmonary injury of UC patients earlier. Serum ET-1 level might be a sensitive indicator reflecting the pulmonary injury of UC. The pulmonary injury of UC patients might be correlated with small airway obstruction, reduced lung elasticity, and injured lung diffusion.</p>

An in vitro detection method of the gastrointestinal absorption of Pilose Antler protein was established for mixed protein activity. Five bands of protein with molecular weight of 17.8-160 kD derived from the Pilose Antler were extracted and sufficiently labeled with FITC (FITC-PE). The stability and variation of FITC-PE in gastrointestinal circumstances were detected by native polyacrylamide gel electrophoresis and confocal laser scanning microscope. Results showed that the main component of FITC-PE kept invariant after being reacted with artificial gastric fluid and artificial intestinal fluid. The fluorescence signal was detected 20 min after administration in the valgus intestinal purse experiment, and three kinds of protein, with molecular weight of 45, 25, and 17.8 kD, were detected in the mixture of absorbent protein. The research laid the foundation for the further in vivo study of Pilose Antler protein. Meanwhile, it would be an in vitro screening method for the absorption, distribution and metabolism of mixed protein from traditional Chinese medicine.
