The results showed that contents of organic residues and heavy metals of styrene type macroporous resin with the preferred method of pretreatment are in line with relevant regulations. It was concluded that this pretreatment method was simple and feasible, which is suitable to be applied in the industrial production.

This paper was aimed to study the genetic diversity and genetic relationship of germplasm resource of Lonicerae Japonicae Flos in order to provide references for its breeding. A total of 36 samples from 18 farm varieties and wild species, as well as related species of Lonicera japonica Thunb. from the main production areas were studied by ISSR-PCR markers. The Jaccard coefficient was worked out by NTSYS-pc software. And a cluster dendrogram of different samples was established based on unweighted pair-group method with arithmetic mean (UPGMA). The re-sults showed that 12 ISSR primers generated 129 loci of which 114 loci were polymorphic. The average percentage of polymorphic bands (PPB) is 88.37%. In the cluster dendrogram, different samples of Lonicera japonica are in the same group, which showed that it is a natural species; the wild sample is separated from the cultivated samples; the traditional type-Maohua is relative stable, but the type of Jizhuahua includes complicated varieties, and it has obvi-ous genetic variation; the new variety Jiufeng 1 has already distinct into one stable type. It was concluded that the ISSR method was suitable for germplasm identification, genetic diversity analysis of Lonicerae Japonicae Flos, thus providing a theoretical foundation for its cultivation and breeding.

This article was aimed to study the chemical constituents in groups of effective components extracted from Xiaoxuming Decoction. Twelve compounds were isolated and purified by dynamic axial compression column chromatography. Their chemical structures were identified by spectral analysis. The results showed that twelve compounds were isolated and identified as octacosanoic acid(1), cetanol(2), oroxylin A(3), wogonin(4), baicalein(5), tetrandrine(6), fangchinoline(7), wogonoside(8), baicalin(9), paeoniflorin(10), amygdalin(11), manntol(12). It was concluded that all compounds were isolated from this compound prescription for the first time.

This study was aimed to evaluate the quality ofYuan-Hu Zhi-Tong (YHZT) tablet from different manufacturers by high performance liquid chromatography (HPLC) fingerprint. An HPLC method was developed to establish the fingerprint of 12 batches of YHZT from 10 manufacturers. The common peaks were confirmed by mass spectrometric analysis. Similarity analysis (SA), hierarchical cluster analysis (HCA) and principal component analysis (PCA) were applied to analyze the fingerprint chromatography. The results showed that there were 15 common peaks in which 12 components were from Corydalis Rhizoma and 3 from Radix Angelicae Dahuricae. The similar degrees of 12 batches of YHZT tablet were between 0.498 and 0.999. Based on the values, they could fall into three groups. The result of HCA showed that 12 batches of samples could be divided into 3 classes. The results of PCA indicated that the first three principal components (PCs) could represent the 15 common peaks. According to the scores of 3 PCs, 12 batches of samples could be divided into three categories. The classification result was mainly affected by the components of Corydalis Rhizoma. The classification results of three methods were basically the same. Based on the combination of three methods, 12 samples can be divided into three grades in the aspect of quality. It was concluded that the quality differences of YHZT tablet from different manufacturers were obvious. The combining application of three methods can be used in the evaluation on fingerprint of samples from different sources and influence factor analysis. It can be used as an effective method for quality evaluation.

This study was aimed to explore effects of Jinzhen Koufuye (JZKFY) on acute lung injury (ALI) induced by lipopolysaccharide (LPS) in rats. Rats were randomly divided into the normal group, model group, positive control group, and three JZKFY groups with the drug dosage of 4.4, 2.2, 1.1 g·kg-1, respectively. Intragastric administration was given to animals for 7 consecutive days. One hour after the last administration, ALI model was induced by the injection of LPS (6 mg·kg-1), and then rats were killed at 16 h after saline (control) or LPS injection. Histological examinations were performed on the lungs. At the same time, the lung permeability index, activities of MPO, MDA and SOD in lung tissues, contents of TNF-α, IL-6 and IL-1β in serum were measured, respectively. The results showed that JZKFY of high-, medium-, or low-dosage can significantly reduce JZKFY lung permeability index. JZKFY of high- and medium-dosage can obviously regulate activities of MPO, MDA and SOD in lung tissues, re-duce contents of TNF-α, IL-6 and IL-1β in serum, as well as significantly improve lung tissue lesions in ALI. It was concluded that JZKFY might improve ALI induced by LPS through inhibiting lung vascular permeability, reduc-ing the lung neutrophil aggregation, improving the ability of antioxidative stress and lowering inflammatory response.

This study was aimed to develop the method for determination of mannitol and meglumine in diterpene lactones of Ginkgo Injection. The HPLC-ELSD was used to determine mannitol and meglumine in diterpene lactones of Ginkgo Injection. The analysis was carried out on Waters XBridge Amide (4.6 mm í 150 mm, 3.5 μm) column. The mobile phase was the mixture of acetonitrile, and 50 mmol·mL-1 ammonium acetate with a linear gradient elu-tion at a flow rate of 1.0 mL·min-1. The column temperature wad maintained at 30℃. The operating conditions of the ELSD were a nebulizer nitrogen with the flow rate of 2.0 L·min-1 and an evaporator tube at the temperature of 90℃. The results showed that mannitol had a good linear relationship in a range of 1.9665 μg - 19.665 μg. The average recovery rate was 100.57% (RSD = 0.92%, n = 9). The meglumine showed a good linear relationship in a range of 0.4838 μg - 4.638 μg. The average recovery rate was 100.67% (RSD = 0.72%, n = 9). It was concluded that this method was simple and accurate with good reproducibility. It met with the requirement of the determination of the contents of mannitol and meglumine in diterpene lactones of Ginkgo Injection.

ObjectiveTo evaluate the efficacy of stereotactic body radiotherapy combined with coinstan taneous gemcitabine,and gemcitabine alone for advanced pancreatic cancer.Methods56 advanced pancreatic cancer patients were assigned into observation group,which accepted stereotactic body radiotherapy combined with coinstantaneous gemcitabine 500 mg/m2,d1,d8.Other 50 patients were assigned into the control group which only accepted gemcitabine 1 000 mg/m2,d1,d8,d15.Stereotactic body radiotherapy was delivered with a total dose of 4 000-4 500 cGy in 10 fractions.ResultsCT examinations were carried out 2 months after treatment.The response rate of the observation group and control group was 82％ and 16％ respectively,and the pain relief rate was 67％ and 17％ respectively.The time to progression of the observation group was 14 months,and was better than that of the control group(7.5 months,x2 =7.31,P =0.032).The median survival time of the observation group and control group was 15.8 months and 13.2 months,and the difference had no statistical significance(x2 =3.28,P =0.082).ConcolusionStereotactic body radiotherapy combined with gemcitabine has a better overall response rate and a pain relief rate.It can prolong the time to progression,but can't improve the overall survival.
