OBJECTIVETo study the conditions and parameters of purifying 2,3,5,4'-tetrahydroxy-stilbene-2-O-beta-D-glycoside from Polygonum multiflori.

METHODAbsorption capacity of four resins for 2,3,5,4'-tetrahydroxy-stilbene-2-O-beta-D-glycoside was compared. With the adsorption ability as indexes, the process of absorbing and purifying 2,3,5,4'-tetrahydroxy-stilbene-2-O-beta-D-glycoside from P. multiflori with S-8 macroporous resin absorbent was selected by orthogonal design.

RESULTThe S-8 resin was the best of the four resins. The optimum process condition was 50% ethanol as eluting solvent, the flow rate at 1.5 mL x min(-1), pH at 7-8, and the solution concentration at 0.2 g x mL(-1). The absorption capacity by this process was 36.89 mg x g(-1).

CONCLUSIONThe process is simple and convenient and the regeneration of resin is easy, so this method of purification is advisable.

OBJECTIVETo evaluate the beneficial effects of application of a self-designed reciprocating gait orthosis (RGO) combined with comprehensive rehabilitation training on bladder and bowel function in paraplegic patients sustaining spinal cord injuries (SCI).

METHODSTwelve paraplegic patients with complete spinal cord injury at the levels between T(4) and L(1) received the RGO with a comprehensive rehabilitation exercise program carried out before and after fixing. Cold water and colon excretion tests were performed before and 3 months after application of the RGO, and the bladder volume, residue bladder volume, and bladder and bowel pressures were measured in these patients.

RESULTSThe 12 paraplegic patients all showed positive results in cold water test before and after RGO application. Before RGO application, 11 of these patients were positive for urine bacteria and only 1 patient was still positive 3 months after the application. The bladder volume and bowel pressure of the patients were significantly increased (P<0.05), while the residue volume and pressure of the bladder were significantly reduced 3 months after RGO application (P<0.05).

CONCLUSIONRGO combined with comprehensive rehabilitation training can effectively improve the bladder and bowel function and the quality of life of patients with complete spinal cord injury, suggesting much clinical value for its extensive application.

ObjectiveProteoglycan TPG-1 isolated from Trametes robiniophila（Huaier） has proved to have anti-hepatoma activity， and this paper aims to explore the molecular mechanism. MethodHuman hepatoma SK-HEP-1 cells were treated with TPG-1 （0， 0.05， 0.1， 0.25， 0.5， 1 g·L^-1）. Then cell survival was detected by methyl thiazolyl tetrazolium （MTT） and apoptosis by flow cytometry. In addition， expression of genes in SK-HEP-1 cells treated with or without TPG-1 was examined by DNA microarray to preliminarily explore the anti-hepatoma molecular mechanism of TPG-1. ResultTPG-1 inhibited the proliferation of SK-HEP-1 cells as compared with the blank group （P<0.01）. After treatment with 1 g·L^-1 TPG-1 for 48 h， the apoptosis rate of SK-HEP-1 cells increased （P<0.01）， and TPG-1 promoted the cleavage of cysteinyl aspartate specific proteinase （Caspase）-3 and Caspase-7， the key mediators of apoptosis （P<0.01）. Additionally， TPG-1 （1 g·L^-1） suppressed the migration of SK-HEP-1 cells （P<0.05）. A total of 971 differentially expressed genes （DEGs） were identified in SK-HEP-1 cells after treatment with TPG-1， with 486 up-regulated and 485 down-regulated. These DEGs were mainly involved in the Gene Ontology （GO） terms of interleukin-6 （IL-6） biosynthesis， antigen processing and presentation， superoxide dismutase activity， positive regulation of mitogen-activated protein kinase kinase kinase （MAPKKK） cascade， nature killer （NK） cell chemotaxis， and chemokine biosynthesis， and the Kyoto Encyclopedia of Genes and Genomes （KEGG） pathways of nucleotide-binding oligomerization domain （NOD）-like receptor signaling pathway， apoptosis， Toll-like receptor signaling pathway， retinoic acid-inducible gene-Ⅰ （RIG-Ⅰ）-like receptor signaling pathway， T-cell receptor signaling pathway， and chemokine signaling pathway. Western blot results showed that TPG-1 （1 g·L^-1） activated mitogen-activated protein kinase （MAPK） signaling pathway in SK-HEP-1 cells （P<0.01）. ConclusionProteoglycan TPG-1 inhibited the proliferation and migration， and induced apoptosis of human hepatoma SK-HEP-1 cells. Up-regulation of MAPK signaling pathway may be responsible for the growth inhibition of human hepatoma SK-HEP-1 cells by TPG-1.

OBJECTIVETo observe the efficacy of the combination of Qilin Pills and levofloxacin in the treatment of asthenospermia accompanied with accessory sex gland infection.

METHODSWe randomly assigned 80 asthenospermia patients with accessory sex gland infection to groups 1 and 2 of equal number, the former treated with Qilin Pills + levofloxacin, and the latter with levofloxacin only. Qilin Pills were administered at the dose of 6 g tid for 30 days, and levofloxacin at the dose of 0.5 g qd for 20 days. We obtained semen parameters, including the percentage of progressively motile sperm and peroxidase-positive white blood cell (WBC) count, before and after medication, and compared the clinical effects between the two groups.

RESULTSAll the patients accomplished the clinical trial. The therapeutic effectiveness rates in improving progressive sperm motility were 60% in group 1 and 17.5% in group 2, with statistically significant differences between the two groups (P < 0.05). As for the peroxidase-positive WBC count in semen, the effectiveness rates were 87.5% and 82.5%, respectively, with no significant differences between the two groups (P > 0.05).

CONCLUSIONFor the treatment of asthenospermia accompanied with accessory sex gland infection, Qilin Pills combined with levofloxacin is evidently better than levofloxacin alone in improving sperm motility, and it has no obvious adverse effects.
