Berberine belongs to the quaternary ammonium type isoquinoline alkaloid known as berberinum. In traditional Chinese medicine, it has long been used to treat infections of the gastrointestinal tract disease caused by bacteria. Recent studies found that berberine has a good anti-tumor effect,but it is difficult pass through the cell membrane due to its poor fat-soluble, which limit its clinical application. By modifing chemical structure, some researchers have investigated the relationship between activity effects and structures of berberine and its derivatives, and have found a series of anti-tumor activity enhanced berberine derivatives. In this review, the recent research progress of the anti-tumor effects and their mechanisms of berberine and its derivatives are focused, which may provide reference for the design and development of anticancer drugs based on the structure of berberine

Study the infect of child anorexia granule on serum ghrelin and leptin of anorexia children and its clinical efficacy. Selected 81 cases of anorexia children aged 1-6 years old into treatment group (42 cases) and control group (39 cases), in addition, 30 case healthy children as healthy control group. The control group children were treated with domperidone suspension 0.3 mg x kg(-1) x d(-1), tid, orally 30 minutes before meals. Treatment group were treated with child anorexia granule, 1-3 years 1 package, bid; 4-6 years 1 package, tid; po, 4 weeks as a course of treatment. Study the change of serum ghrelin and leptin before and after therapy. The study demonstrates that before treatment, the serum ghrelin level of disease group was lower than healthy group (P < 0.01), and the serum leptin level was higher than healthy group (P < 0.01). After treatment, the serum ghrelin level both increase, and the serum leptin decline. And the change of treatment group was significantly different with control group (P < 0.01). And the clinical effective rate are 95.23% and 74.35% (P < 0.01). After 6 months of follow-up visit, the children weight significantly increase in treatment group (P < 0.01). Results indicate that child anorexia granule can facilitate secretion of ghrelin, and inhibit secretion of leptin, so as to work up an appetite. And the molecular mechanism is its infect on serum ghrelin, leptin.

There is no radical cure for essential thrombocythemia currently. Professor SUN Xue-mei has extensive clinical experience in treating it by combined therapy of Chinese and Western medicine. In this paper, authors tried to summarize her experience from guiding ideology and therapeutic points. Authors insisted on the direction of integrative medicine on the basis of syndrome differentiation, paying attention to psychological counseling,and applied individual treatment in clinics.

In the treatment of hypertensive crisis, the novel Rho kinase inhibitor DL0805-2 can rapidly lower systematic blood pressure, reduce pulmonary artery pressure, and has a significant protective effect on lung injury. This experiment intends to evaluate the efficacy of DL0805-2 against pulmonary arterial hypertension (PAH) and preliminarily reveals its underlying mechanism. Animal welfare and experimental procedures are in accordance with the provision of the Animal Ethics Committee of the Institute of Materia Medica, Chinese Academy of Medical Sciences. Sprague Dawley (SD) rats were randomly divided into DL0805-2 low, medium, and high dose groups (1, 3, and 10 mg·kg^-1), bosentan positive control group, model group, and blank control group. The drug was administered daily on the 7th day after model establishment by monocrotaline injection. On the 25th day of the experiment, relevant indicators were examined to observe the therapeutic effect of DL0805-2 on pulmonary hypertension. DL0805-2 significantly relieved the abnormal changes in the physiological parameters related to PAH induced by monocrotaline, including reducing right ventricular systolic pressure, alleviating cardiac damage caused by pressure overload, and reducing the levels of endothelin-1 and inflammatory factors in lung tissues. DL0805-2 also attenuated pulmonary arteries remodeling. It was preliminarily discovered that DL0805-2 exerts preventive and therapeutic effect on PAH through Rho-kinase pathway. Our results suggested that DL0805-2 had good therapeutic effects on monocrotaline-induced PAH rat model. It intervened early in the disease process, effectively prevented the development of the disease, and reduced the mortality of the diseased animals. The mechanism is related to Rho-kinase pathway.

Objective To investigate the effects of cognitive interventions (CIs) in the context of communi- ty based rehabilitation (CBR) on cognitive deficits (CDs) in stroke patients.Methods Ninety-two stoke patients with CDs were randomly divided into a CI group and a control group.All patients were treated with conventional CBR.In addition,the patients in the CI group were also treated with special intervention therapy.The patients in both groups were assessed with the neurological and cognitive status examination (NCSE) for cognitive functioning, the FCA for motor function and the BI for their ability in the activities of daily living.Results The NCSE,FCA and BI scores in the cognitive intervention group after treatment were significantly higher than those before treatment and also significantly higher than those in the control group after treatment.Conclusion CIs can not only improve CDs,but also enhance recovery of motor function and ADL.

OBJECTIVETo analyze the data of angle variation on traction based on a finite element model of complete cervical spine with straight physiological curvature, and try to give experimental reference and suggestion in treating cervical spondylosis.

METHODSA 43-year-old female patient with straight cervical spine was chosen and the CT scan data were collected. By using specially designed modeling system, a high quality finite element model of complete cervical spine with straight physiological curvature is generated,which included ligament and muscle according to anatomy. After the model was confirmed, traction was loaded with angle 0 degree, anterior 5 degrees, 10 degrees, 15 degrees, 20 degrees, 25 degrees, to observe the data of distance change on between adjacent intervertebral foramen, processus articularis, uncovertedral joint, intervertebral discs, and stress of anulus fibrosus and nucleus pulposus.

RESULTSWhen the angle was 0 degrees-15 degrees, the distance between intervertebral foramen, Luschka joint and processus articularis posterioris was enlarged, the tensile stress was adequate and compressive stress was small. It met the clinical requests.

CONCLUSION0 degree-15 degrees anterior position is suggested for the treatment of cervical spondylosis.
