Object To study the feasibility of suspension culture of protocorm in Dendrobium candidum Wall ex Lindl and effect of inoculum and medium volume on the growth of protocorm Methods Effect of four basic media MS, 1/2 MS, 67 V, and B 5, inoculum and medium volume on the growth of protocorm were studied by completely random experimental design and orthogonal test design Results The growth of D candidum protocorms in liquid medium was markedly better than that in solid medium (P0 05), B 5 was much better than 1/2 MS (P

The pediatric risk of mortality Ⅲ(PRISM Ⅲ) score and pediatric critical illness score(PCIS) are physiology-based scores for assessing the severity of illness and mortality risk in pediatric patients.The PRISM Ⅲscore was revised version of the PRISM and was first developed in 1996.It includes 17 physiologic variables subdivided into 26 ranges.It had been validated by numerous studies worldwide and is the most widely known and used at pediatrics intensive care unit(PICU).The PCIS was first developed in 1995 in China,which included 10 physiologic variables.It had been validated by numerous studies nationwide and was simple,effective and suitable to Chinese situations.The scoring systems also can be used for quality assessments,grading the severity of illness in clinical study,and(stu)-dies of ICU resource utilization and management.There were no such study for validating the PRISM Ⅲ at present,comparing the performance of the PRISM Ⅲ score and the PCIS in China.

Cystatin Cystatin(CST)is a class of proteins that inhibit cysteine proteases and are widely distributed in human body fluid and secretion.The present study shows that the CST superfamily is closely related to the tumor,in which the cysteine protease inhibitor SN is the product expressed by the CST1 gene and is abnormal expression in various tumors.However,its occurrence and development of tumor as well as effects of invasion and metastasis on the specific mechanism is not yet clear.In this paper,we retrospectively analyze the related studies in recent years and review the progress of CST1 gene in tumor.

Objective To study the hemoprotective effects of a rotary magnetic field(RMF)with radiation- injured mice.Methods C57 BL6/J mice were randomly divided into a control group and a magnetic treatment group.The mice received total body irradiation with 7.0 Gy and 6.5 Gy ~(137)Cs?rays.The treatment group was trea- ted with a RMF for one hour at a time,twice a day.The intensity of the RMF was 0.6T.The survival rate was ob- served for 30 days.On day 7,10,14,21,28 after irradiation,the subjects' peripheral blood cells were counted.On day 12 and 16,the number of bone marrow mononuelear cells(BMNCs)was measured and their ability to form granu- locyte-macruphage colony-forming unit(CFU-GM)was assessed.The pathological sectioning of the femur was per- formed and the expression level of bone morphogenetic proteins(BMPs)in the bone marrow were evaluated.Re- sults The RMF treatment increased the survival rate and duration among the irradiated mice and the number of blood cells in their peripheral blood.Also,RMF treatment could increase the number of BMNCs and improve their ability to form CFU-GM on days 12-16.Furthermore,RMF could improve angiogenesis and the expression level of BMPs. Conclusion The RMF treatment had an obvious protective effect against the effects of irradiation,and it accelerated the recovery of hematopoiesis and the hematopoietic microenviroment in mouse bone marrow.

Teaching purpose, teaching content, experiment and examination forms etc. were discussed, and how to practice the teaching of the public selective course Nutriology of Traditional Chinese Medicine was pointed out. All these are invaluable experience for the development and progress of this course.

Objective In order to offer a noninvasive and objective examination method for assessing the clinical diagnosis and eurative criterion of concussion patients, the patients color three - dimensional transcranial doppler( 3D - TCD) characteristic at deferent phases, parameter and clincal manifestation were studied Method Parameter of Median Cerebral Artery(MCA), Base Artery(BA), the average peak forwand velocity of cerebral blood flow, train figure were tested by 3D - TCD within 24 hours, 3 - 6 days and at the end of treatment, respectively. The results were compared with clinical diagnoses and curative criterion. Result Among 135 patients who had clinically diagnosed concussion, agreeable diagnoses 101 cases, basically agreeable diagnooses 12 cases, disagreeable diagnosis 22 cases(16. 2%) .At the end of treatment, according to clinical determination 96 cases(71.1%) were cured, 39 cases(28.9%) were improved. Wave train character, figure and diagnoses prameter of cerebral spasm caused by concussion were suggested Conclusion To be one of the diagnostic bases and curative criterion, 3D- TC D technology is performable. Meanwhile, it is a new testing objective technique for assessing curative and determining prognosis.

Objective To evaluate the effect on treatment of multiple myeloma complicating femoral neck fracture by surgical intervention combined with drugs.Methods Twelve patients with multiple myeloma complicating femoral neck fracture were treated by cemented total hip arthroplasty femoral head shank.All of patients were received zoledronic acid treatment,at the same time,7 cases of them treated by MPT regimen (melphalan,methylprednisolone and thalidomide),3 by bortezomib combined with dexamethasone,and 1 by autologous peripheral blood stem cell transplantation.Results Twelve patients could tolerate surgery,postoperative pain was significantly reduced.Assessed by using Harris hip function score after 6 months operation,2 cases were excellent,7 cases were good,3 cases were common,excellent and good rate was 75％ (9/12).All patients were followed up for 8 months to 3 years,1 case of local recurrence after 13 months.1-year overall survival rate was 100％,2-year overall survival rate was 83％,and 3-year overall survival rate was 67％.Conclusions Multiple myeloma complicating femoral neck fracture,using bone cement in total hip arthroplasty femoral head shank to clear the local tumor lesions,receive reconstruction capability,rapid postoperative recovery,pain relief,and opportunities for further comprehensive treatments.The bisphosphonate can promote new bone formation and prevent further fractures.The surgical intervention combined with chemotherapy could relieve the symptoms,reduce tumor cell burden,improve quality of life and prolong survival time.
