Hedysari polysaccharide (HPS) is the main component of hedysarum polybotrys. HPS can inhibit tumor cell proliferation, block the cell cycle in the G2-M period, modulate apoptosis via the mitochon drial pathway, and improve the red blood cell innate immunity and T lymphocyte immune function. HPS can relieve low immunity caused by chemotherapeutics.HPS plays anti-tumor effects by these ways mentioned above.

Objective To analyze the data of concentric (c) and eccentric (e) peak torque of hamstring (H) and quadricep (Q) in differ-ent gender and angle after 4-week concentric and eccentric isokinetic exercise training on knee, in order to provide suggestions for the knee extensor and flexor in rehabilitation exercise prescription. Methods 28 healthy college students from May to June 2014 in our college partic-ipated in maximum concentric (n=14) or eccentric (n=14) resistance training of the right knee extensors and flexors 3 times per week for 4 weeks. The concentric strength was measured with BIODEX isokinetic dynamometer assessment system 4 at 30 °/s, 60 °/s, 90 °/s, and ec-centric strength was measured at 60 °/s, 120 °/s, 180 °/s. PT, H/Q (He/Qc, Hc/Qc) ratio and H/H (He/Hc) or Q/Q(Qe/Qc) ratio were ana-lyzed. Results Concentric isokinetic training could improve the Hc and He at 60 °/s and 90 °/s (P<0.05), and the Qe and Qc increased at 30 °/s, 60 °/s, 90 °/s respectively (P<0.01). There was no significant improvement after eccentric training (P>0.05). After concentric isokinet-ic training, the He/Qc ratio decreased at 90 °/s (P<0.05), the Hc/Qc ratio decreased at 30 °/s (P<0.05). However, there was no difference in He/Qc and Hc/Qc after eccentric contraction (P>0.05). The Qc/Qe ratio increased at 60 °/s and 90 °/s (P<0.05), and the Hc/He ratio de-creased at 90 °/s (P<0.05) after concentric training. There was no difference in Hc/He and Qc/Qe after eccentric contraction (P>0.05). There were significant differences in Hc, He, Qc, Qe and He/Qc ratio between different genders (P<0.05). Conclusion Concentric training and ec-centric training have different influences on the muscle strength after 4 weeks training. Eccentric training only can reduce the knee stability. Hc/He ratio and Qc/Qe ratio can be used to evaluate the knee muscle function. Gender should be considered into training.

The strain Streptomyces sp.,nominated IMB-14,was isolated from the soil sample of WuDang Mountain by the method of cellulose ester membrane filter.The studies on antibiotic activities,morphological characteristics,cultural characteristics,physiological characteristics,16S rDNA sequence analysis and the metabolite of strain IMB-14 showed that the strain IMB-14 was accordance with Streptomyces xanthoci-dicus.The study on the isolation and identification of strain Streptomyces xanthocidicus establishes a foundation on screening of novel antibacterial and antitumor agents.

The apoptosis of cardiac muscle cells refers to an initiative cell death process that is controlled by a series of genes, and in fact it is a kind of physiological cell death. The authors of this article reviewed and analyzed the biology characteristics and development mechanisms of the apoptosis of cardiac muscle cells, summarized the research progress of the apoptosis of cardiac muscle cells and exercise, so as to offer theoretical reference for exercise training and heart protecting.

Objective To develop a holding mechanism for the drainage bag to reduce the accident rate of tube falling off during CT examination.Methods The mechanism was composed of a bed body,a mobile bed board,a connecting board,a rod and kink section.CT bed board had a sandwich structure with carbon fibre composite and foam material,and the connecting board,kink section,rod and its hinge joint were made of polycarbonate material.Results The mechanism decreased the risk for tube falling off during CT examination and increased the patient comfort.Conclusion The mechanism gains advantages in stability,mobility,convenience and practicability,and thus is worthy promoting practically.

The ?-radioactive seed brachytherapy source has been widely employed in the implantation therapy for the prostatic carcinoma and the ophthalmic lesions.In this study the dosimetric parameters for characterization of a low-energy interstitial brachytherapy source 125I were calculated according to dose calculation formalism recommended by AAPM TG-43U1.For data processing,a 0.28 cm active length was used for the geometry function.The dosimetry parameter air-Kerma strength,dose rate constant,radial dose function and anisotropy function were estimated by means of the EGS5 Monte Carlo code.The results obtained from this study are in good agreement with the corresponding values recommended by TG-43U1 and with the data reported by Dolan,et al.

Objective To investigate infection situation and knowledge of high‐risk human papilloma virus(HPV)among women working in entertainment places in Gaoqiao area ,and provide theory evidences for making health education measures related to high‐risk HPV .Methods According to the systematic random sampling method ,entertainment female in Gaoqiao area were extracted , and normal women who participated in community gynecology census were extracted as control group .Then questionnaire investiga‐tion and laboratory testing were carried out .Results The infection rate of high‐risk HPV in entertainment female was 35 .18% , while in normal woman was 15 .84% ,there was significant differences of infection rate between the two groups (P<0 .05) .There were were only 16 women(14 .81% )and 17 women(16 .83% )had heard of information about HPV in two groups respectively ,and there was no statistically significant difference(P>0 .05) .The cognitive situation of whether a person with family history of cervi‐cal cancer should be regularly attend screening among the two groups of women was different ,and had significant difference(P<0 .05) .Conclusion Women who worked in entertainment places had higher infection rate of high‐risk HPV ,both of the two groups had poor knowledge of HPV .So the propaganda and screening of HPV should be strengthen in order to raise consciousness in pre‐venting cervical cancer .
