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.

Objective: To observe the effect of phlegm and blood stasis on the expressions of sirtuin 3(SIRT3)protein and urate transporter 1(URAT1) mRNA in skeletal muscle of diabetic rats with gout. Method: The 40 healthy rats, excepting the normal group, the remaining groups were fed with high-fat diet combined with low-dose streptozotocin solution (40 mg·kg-1) once a day, with blood glucose "16.7 mmol·L-1" as the criterion for the diabetes model. After 4 days, the 5% sodium urate solution was injected into the joint cavity once to induce the gout model. After the successful modeling, the Biling group (10 g·kg-1), the indomethacin group (5 mg·kg-1) and the pioglitazone group (10 mg·kg-1) continued to be administered for 21 days. The normal group and the model group were given the same amount of normal saline. The expression of SIRT3 protein in skeletal muscle tissue was determined by Western blot, URAT1 mRNA expression in bone tissue was detected by quantitative real-time fluorescence polymerase chain reaction(Real-time PCR),and blood was collected to measure blood glucose (GLU), blood uric acid (UA) and C-reactive protein (CRP). Result: Compared with the normal group, GLU, UA and CRP in the model group were significantly increased (P<0.01). Compared with the model group, GLU in the Biling group and the pioglitazone group were decreased, and UA and CRP in the medicine group were significantly decreased (P<0.05,P<0.01). Compared with the normal group, the expression of SIRT3 protein in the skeletal muscle of the model group was significantly decreased (P<0.01), while the expression of SIRT3 protein in the skeletal muscle of the Biling group was significantly increased after administration (P<0.01). Compared with the model group, the expression of SIRT3 protein in the skeletal muscle of the sputum group was significantly increased (P<0.01), with no significant difference from the western medicine group. The results of the strip chart also showed that compared with the model group, the expression brightness of the model group was significantly weakened, while the expression brightness of the drug group was significantly enhanced. Compared with the normal group, the relative expression of joint URAT1 mRNA in the model group was significantly increased (P<0.01). Compared with the model group, the relative expression of URAT1 mRNA in each drug group was significantly down-regulated (P<0.01). The results of the strip chart also showed that expression brightness of the normal group was the weakest, while that of the model group was the highest, and the expression brightness of the Biling group and the western medicine group was significantly weakened. Joint pathology suggested that compared with the normal group, the pathological damage of the joints in the model group was severe, with a large number of inflammatory cell infiltration and fibrosis, synovial cell degeneration and necrosis. Compared with the model group, the degree of joint disease was significantly reduced after treatment with Biling Qutong prescription, with only a small amount of inflammatory cell infiltration and mild hyperplasia in synovial epithelium. Conclusion: Biling Qutong prescription with effects in purging turbidity, detoxifying and dredging collaterals can significantly reduce the content of serum inflammatory factor CRP, significantly increase the protein expression of SIRT3 in skeletal muscle tissue of model rats, lower the content of URAT1 mRNA, reduce the blood glucose and blood uric acid levels in diabetic gout rats, and protect joints.

OBJECTIVE:
To study the effects of astragaloside-IV (As-IV) on the expression of inflammatory factor and proliferation of glomerular mesangial cells (GMCs) induced by angiotensin Ⅱ(AngⅡ).
METHODS:
The model of diabetic nephropathy(DN) was mimic by angiotensin Ⅱ (10mol/L)inducing GMCs injury. Then the GMCs were treated with As-IV at different concentrations(25,50,100 μmol/L)for 48 hours. The proliferation of GMCs was detected by MTT. The level of reactive oxidative species (ROS) was measured by flow cytometry. The expression of monocyte chemoattractant protein-1(MCP-1) protein in supernatant was detected by enzyme- linked immunosorbent assay (ELISA). The expression of transforming growth factor-β1(TGF-β1) in GMCs was measured by Western blot.
RESULTS:
Compared with model group, the proliferation of GMCs was inhibited in As-IV group. As-IV decreased the level of intercellular ROS, down-regulated the secretion of MCP-1 and the expression of TGF-β1 proteins.
CONCLUSIONS
As-IV could inhibit cell proliferation and inflammatory factors expression on GMCs induced by AngⅡ.

Objective: To explore age-related clinical characteristics, early responses and outcomes in non-senile adults with de novo acute myeloid leukemia (AML). Methods: Data of consecutive cases of 18-65 years adults with de novo AML (non-acute promyelocytic leukemia) were reviewed retrospectively. Clinical characteristics at diagnosis, early responses and outcomes across different age groups of patients were analyzed. Results: 1 097 patients were enrolled. 591 (53.9%) were male. Median age was 42 years. Increasing age was significantly associated with decreasing WBC count (P=0.003), increasing PLT count (P=0.034), lower blast proportions in bone marrow (P=0.021). The incidence of NPM1(+)/FLT3-ITD(-) increased with age (P<0.001). Multivariate analyses showed that increasing age was associated with low probabilities of achieving morphologic leukemia free state (MLFS) (P=0.053) and complete remission (CR) (P=0.004) and poor overall survival (OS) (P=0.070) in the whole patients population. However, increasing age was not associated with low MLFS rate and poor OS, except low CR rate (P=0.075) in those receiving standard induction regimen instead of low-intensity regimen. Conclusions: There were significant differences on clinical characteristics, cytogenetics and molecular genetics across different age groups in non-senile adults with de novo AML. In the patients receiving standard induction regimen, age was not associated with MLFS rate and OS.

6.Advance and prospect in studies on anaphylactoid reaction of traditional Chinese medicine injections.
China Journal of Chinese Materia Medica 2015;40(14):2765-2773
Because of the rapid action and high bioavailability, traditional Chinese medicine injections (TCMIs) had been widely used in clinical critical field. In recent years, with the increasing reports of clinical adverse reaction, more and more attention was paid to them, and acute allergic reaction was the main adverse reaction. Acute allergic reaction included type-I anaphylaxis reaction and anaphylactoid reaction, the latter had been found in a variety of TCMIs and accounted for 77% of adverse reaction. But the mechanism of anaphylactoid reaction was not completely understood, the standard animal model for TCMIs was not established, and the technical guidance for anaphylactoid reaction was not formulated. Thus the three aspects included mechanism, evaluation index and evaluation methods of TCMIs for anaphylactoid were reviewed. Five ways including direct stimulating pathway, complement pathway, coagulation pathway, kallikrein-kinin pathway and acute allergic pathway were the main mechanism of anaphylactoid reaction; whole animal model and cell model were the main evaluation methods; the occurrence index and effect index were reviewed for the evaluation index analysis.

With the combined applications of steam distillation, water extraction and alcohol precipitation, liquid-liquid extraction and column chromatography over macroporous resin, a splitted-fractions method of the chemical constituents of Poria cocos was established. The unoverlapping property of the fractions of P. cocos was qualitatively analysed by using principal component analysis and cluster analysis. With angle cosine, squared euclidean distance and the overlapping analysis of peak area of crude herbs, the unoverlapping property of the fractions of P. cocos was half-quantitatively analysed. The chemical components of P. cocos was divided into the fractions of polysaccharide, petroleum ether, ethyl acetate, alcohol eluate from macroporous resin and water eluate from macroporous resin. Non similarity degree among each chemical fraction was above 80% and main chemical components were identified. The established method for splitting fractions of P. cocos has good stability and repeatability and all chemical components in P. cocos could be completely divided into six fractions. It is the first time that the author half-quantitatively analyse the unoverlapping property of the chemical fractions of P. cocos.
