There are many progresses in the therapy of MM with ASCT. ASCT improves the ratio of CR,EFS and OS,compared with conventional chemotherapy.Myeloma patients with renal failure or old age also can be candidate for ASCT.Tandem autologous transplantation improves the ratio of CR. Its impact to long-term EFS and OS still need to be judged.To improve conditional project,to choose suitable time,and- toselect consolidation schedule can boost therapeutic effect.

?Optic neuritis ( ON) is one of the most common causes of vision loss by neural eye diseases in youth and middle-aged. In the past, the diagnosis simply according to the risk position, which did not distinguish from the pathogenesis and clinical characteristics, can not meet the current clinical diagnosis and treatment needs. Combining with the etiology, clinical characteristics and prognosis, the latest classification of the current international diagnosis of ON are typical and atypical ON. Typical ON relates to multiple sclerosis ( MS ) or demyelinating disease of the central nervous system, it has a relatively good therapeutic effect and prognosis. Rather than, atypical ON has complex etiology, clinical manifestation, and the treatment and prognosis are also different. At present there are many international ON treatment guidelines with level I evidence-based medical evidence, but with different genetic background, geographical environment and ethnic groups, they are not been determined. China lacks of such a multicenter large sample, a wide range of research evidence. In this paper, we will summarize the progress of the diagnosis and treatment about ON, especially about the atypical ON, in order to provide some suggestions to further improve the standardization and individualization for clinical diagnosis and treatment on ON.

To reveals the effects of tree species on polysaccharides content of epiphytic Dendrobium officinale. The polysaccharides content of D. officinale attached to living tress in wild or stumps in bionic-facility was determined by phenol-sulfuric acid method. There were extremely significant differences of polysaccharides content of D. officinale attached to different tree species, but the differences had no relationship with the form and nutrition of barks. The polysaccharides content of D. officinale mainly affected by the light intensity of environment, so reasonable illumination favored the accumulation of polysaccharides. Various polysaccharides content of D. officinal from different attached trees is due to the difference of light regulation, but not the form and nutrition of barks.

Objective To analyze the correlation factors between CT imaging features of pulmonary embolism(PE)and clinical severity stratification,to explore the value of CT pulmonary angiography (CTPA)in acute PE severity stratification.Methods According to the clinical severity,48 patients with acute PE proved by CTPA were classified into two groups,including 21 critical and 27 non-critical patients. Embolism index,ratio of central pulmonary involvement,ratio of right ventricle maximum minor axis (RVMMA)to left ventricle maximum minor axis(LVMMA),namely RV:LV,dilation of main pulmonary and/or right pulmonary trunk,and dilation of bronchial arteries in both groups were analyzed comparatively. The correlation factors between CT imaging features and PE clinical severity stratification were explored.The correlation between RV:LV and embolism index of 48 patients was analyzed.Results Pulmonary embolism index(22.0%—85.0%,median 38.0%),ratio of central pulmonary involvement(42.5%),RV:LV (0.90—1.90,median 1.30),dilation of pulmonary artery(14 cases),and dilation of bronchial artery (8 cases)in critical group(21 cases)were higher than those corresponding factors(5%—48%,median 21.5%,31.25%,0.80—1.40,median 1.00,5 eases,and 3 eases)in non-critical group(27 cases) (Z=4.27,X~2=5.40,Z=2.58,X~2=11.45,X~2=4.87,P

AIM: To observe the surgical effects of the taumatic lens subluxation and cataract after manual fragmentation and emulsification of nucleus and foldable intraocular lens implantation.
METHODS: A 3. 0mm tunnel limbus incision was operated through the predicted bulbar conjunctiva and sclera on 26 cases ( 26 eyes ) with taumatic lens subluxation ( suspensory ligament rupture range less than 120 ) and cataract (Ⅰ ~ Ⅲ) . And after the manual fragmentation and emulsification of nucleus, foldable intraocular lens was implantated. Intraocular lens loop was imbedded in the middle of the lens zonular ligament breakup to reset the pouch. The surgical complications and postoperative vision changes were observed.
RESULTS:Three month after operation, 22 eyes had a intraocular lens centric position taking up 85% of the whole. Four eyes had a slightly eccentric position ( 1 ~2mm), taking up 15% of the whole. 21 eyes had their visual acuity 0. 5~0. 8, taking up 81% of the whole. Five eyes of visual acuity was 0. 2~0. 8. Within 24h intraocular pressure of 12 eyes (46%) after operation were elevated, and returned to normal after 2~7d. There was no severe complication during operation and postoperation.
CONCLUSION: The manual fragmentation and emulsification of nucleus and foldable intraocular lens implantation of the traumatic lens subluxation and the cataract through the 3. 0mm corneal sclera limbus tunnel incision is a simple and effective surgery.

OBJECTIVETo study the mechanism of stem cell factor (SCF) in bone marrow stem cells heart transplantation (BMT) and the influence of bone marrow mobilization on the transplantation efficacy.

METHODSRats with acute myocardial infarction (AMI) accepted BMT. The SCF expression in the bone marrow was measured by RT-PCR after the operation. Then bone marrow stem cells with different SCF levels for the transplantation were used and the cardiac function was compared by using echocardiography. The SCF protein expression in the heart, plasma and bone marrow was detected by ELISA.

RESULTSSCF expression level decreased significantly 1 week after AMI (P < 0.01), but it didn't decrease in those accepting BMT. Though the rats accepted BMT with bone marrow stem cells from different sources, the cardiac function showed no difference (P > 0.05). After BMT, the SCF protein level in the plasma decreased significantly (P < 0.05).

CONCLUSIONSBMT may make mobilization through SCF. Bone marrow stem cells from rats with AMI and also those with myocardial infarction plus BMT therapy can also be used for the transplantation into heart, and have no influence on cardiac function improvement.

A method of comprehensive chemical pattern recognition of Atractylodis Rhizoma was established by GC-MS fingerprint, principal component analysis, cluster analysis and discriminant analysis. A DB-wax column (0.25 mm x 60 m, 0.25 microm) with El ion source and 70 V electron multiplier were used for GC-MS analysis. Using principal component analysis, cluster analysis, and discriminant analysis, 15 common peaks of sample fingerprints for chemical pattern recognition research were analysed. The same results were obtained from the fingerprint, principal component analysis and cluster analysis, which could use to distinguish genuine Atractylodes lancea, ungenuine A. lancea and A. chinensis. Thus, this method could be used for the quality control and comprehensive evaluation of Atractylodis Rhizoma.

A hydroponic experiment carried out to study the effect of five Cd levels on growth and photosynthesis of two tomato cultivars showed that the addition of 0.1 micromol/L Cd induced a slight increase in plant height of Hezuo 903 and the SPAD (the Soil-Plant Analyses Development) value of the 2 cultivars. However, at higher Cd levels, i.e., 1 and 10 micromol/L, root length and volume, plant height, and SPAD value were all significantly reduced. On an average of the 2 cultivars, exposure to 1 and 10 micromol/L Cd for 33 d reduced plant height by 18.9% and 46.4% and SPAD value by 11.2% and 31.6%, compared with control, respectively. Similarly, root length was reduced by 41.1% and 25.8% and root volume by 45.2% and 63.7%, respectively. The addition of Cd in the growth medium also had significant deleterious effect on net photosynthetic rate (Pn) and intracellular CO(2) concentration (Ci), with Pn being reduced by 27.2% and 62.1% at 1 micromol/L and 10 micromol/L Cd treatments compared to the control, respectively, while Ci increased correspondingly by 28.4% and 39.3%.
