Objective:To evaluate the benefit of autologous stem cell transplantation (ASCT) as a consolidation therapy in the survival of multiple myeloma (MM) patients at different risks. Methods:A total of 67 MM patients who received ASCT as consolida-tion therapy between August 2006 and July 2011 were enrolled in the retrospective study. The cases were divided into three risk groups on the basis of the International Staging System and fluorescence in situ hybridization. Another 67 patients who accepted consolidation chemotherapy at the same period were selected as case-paired controls matched in terms of age, sex, optimal response after induction, and risk stratifications. All the patients received bortezomib-and/or thalidomide-based induction therapies. Results:No statistical differ-ences in non-complete remission (nCR)/complete remission (CR) rate were observed between the ASCT and chemotherapy groups (44.8%vs. 37.3%, P=0.380) after the induction therapy. The progression-free survival (PFS) was longer in the ASCT group than in the chemotherapy group (32.4 months vs. 15.1 months, P<0.001). The overall survival (OS) was longer in the ASCT group than in the che-motherapy group (58.8 months vs. 42.1 months, P=0.009). both the PFS (median:30.5 months vs. 11.2 months, P<0.001) and the OS (median:85.5 months vs. 34 months, P=0.015) rates were significantly prolonged in the high-risk subgroup after ASCT. In the interme-diate-risk subgroup, neither PFS nor OS showed any significance after ASCT (P>0.05). In the low-risk subgroup, only PFS was extend-ed (median: 34.8 months vs. 17.6 months, P=0.012) after ASCT, without significant improvements in the OS (P>0.05). Conclusion:The MM patients obtained cytogenetic high-risk benefits mostly from ASCT consolidation after inductions based on novel agents.

The paper is aimed to study the difference in yield and quality at different harvest time and determine the optimum harvest of planting Gentiana in Ludian traditional harvest period. The authors analyzed the variation in fresh weight, dry weight, dry discount rate, length, diameter, volume and the content of gentiopicroside, loganin acid, alcohol-soluble extract and total ash and made a comprehensive appraisal of yield, appearance quality and intrinsic quality by gray relational distance ideal Comprehensive Evaluation method. The results showed that there is a big difference in yield and quality both 2-year-old and 3-year-old Gentiana harvested in traditional harvest period and the comprehensive evaluation more better when harvested more later. It can be seen, Gentiana harvested the later had a better yield and quality in Ludian traditional harvest period. The harvest of Gentiana can be appropriate delayed depending on the particular circumstances of production.

[Objective] Based on the resting state functional magnetic resonance imaging to investigate the abnormal features of the functional connectivity of resting brain neural network in the patients with primary insomnia,by using voxel-wise whole-brain finctional networks analysis of degree centrality (DC) for imaging evidence of neural mechanisms underlying primary insomnia.[Methods] The resting state fMRI were performed in 59 PI patients and 47 age,education,and sex-matched normal healthy subjects.Analysis of DC map changes between the two patient groups and the control group were performed by two sample t test.(threshold at P ＜ 0.05).[Results] Compared with the control group,the patients with PI showed significantly reduced DC value in bilateral medial frontal gyrus (MFG),bilateral anterior cingulate gyrus (ACG),and right insula;and increased DC value in right middle temporal gyrus (MTG),and left cuneus,(CUN),P ＜ 0.05.[Conclusion]Changes of DC value occurred in some region of brain in the P[patient groups when compared with the control group.It was indicated that DC,as a novel resting-state fMRI parameter in the voxel-wise whole-brain functional networks,might be an appealing alternative approach for further study on pathologic and neuropsychological states of PI.

Objective To investigate how to diagnosis traumatic subdural effusion (TSE) and differentiate it with senile encephalatrophy in aged people by CT scan. Methods Fifty-two aged patients with TSE and 40 aged patients with encephalatrophy, admitted to our hospital from March 2008 to March 2010, were chosen in the study. Their clinical data and CT manifestations were retrospectively analyzed and compared. Results Fifty-two patients with TSE had 91 sites of the lesion, including 31 lesions located in temporal-frontal lobe and 30 lesions in frontal lobe. Among the 52 patients, 34 were also noted as having encephalatrophy. First-time CT demonstrated 32 patients with TSE, and the second-time CT on the left patients showed 20 having TSE too. Among the 52 patients, increasing amount of fluid in a short term was noted in 32 patients; local widened gyri with a flattened surface and narrowed sulci was presented in 30; "compressed arachnoid sign" was found in 9. CT results demonstrated that no above-mentioned manifestations were presented in patients with encephalatrophy.Conclusion For aged person, TSE is usually located in the temporal and frontal lobe, and should be differentiated with senile encephalatrophy. The key-points for differentiation include the location and the extent of changes of extra-cerebral space, the space-occupying signs as local flattened gyri and narrowed sulci, the appearing of "compressed arachnoid sign" and the changes of effusion in a short-term review.

OBJECTIVETo explore the mechanism of miR-124 inhibiting the proliferative activity of prostate cancer PC3 cells.

METHODSLuciferase reporter gene assay was used to examine the specific binding ability of miR-124 to PKM2 mRNA 3'-UTR. After miR-124 was transfected mimic to PC3 cells, the expression levels of PKM2 mRNA and protein were detected by real-time fluorescence quantitative PCR (qRT-PCR) and Western blot, respectively. The effects of miR-124 mimic and PKM2 siRNA on the proliferative activity of the PC3 cells were determined by MTT assay.

RESULTSThe expressions of PKM2 mRNA and protein were upregulated (5.12 +/- 0.35) times and (4.05 +/- 0.20) times respectively in the PC3 cells as compared with those in the RWPE-1 cells (P < 0.05). Luciferase reporter gene assay demonstrated that miR-124 targeted PKM2 3'-UTR. At 24 hours after transfection with miR-124 mimic, the PKM2 protein expression in the PC3 cells was downregulated (0.16 +/- 0.04) times (P < 0.05), while the PKM2 mRNA level was not changed significantly (P > 0.05), as compared with the control group. MTT assay showed that both miRNA-124 mimic and PKM2 siRNA could inhibit the proliferation of the PC3 cells, but the former exhibited a greater inhibitory effect than the latter. After transfection with miR-124 mimic and PKM2 siRNA, the cell growth rates were (66.20 +/- 5.10)% vs (82.10 +/- 6.35)% at 24 hours (P < 0.05) and (49.34 +/- 2.37)% vs (70.10 +/- 5.80)% at 48 hours (P < 0.05).

CONCLUSIONmiR-124 can suppress the proliferation of PC3 cells by regulating the PKM2 gene.

OBJECTIVETo explore the early rehabilitation effect of acupuncture on brain arousal in severe craniocerebral injury.

METHODSOne hundred and two cases of severe craniocerebral injury were randomly divided into an observation group and a control group, 51 cases in each one. Based on the conventional nursing care in neurological external medicine, in observation group, acupuncture was applied at Shuigou (GV 26), Neiguan (PC 6) and Sanyinjiao (SP 6) mainly. In control group, functional electric stimulation was applied at stimulate the affected muscles of the upper limbs. Thirty days later, the lucid rate from coma, lucid interval and clinical efficacy were compared between two groups. RESULTS; The lucid rate from coma was 82.4% (42/51) in observation group, which was higher than 56.9% (29/51) in control group (P < 0.01). The lucid interval in observation group was shortened remarkably as compared with control group (P < 0.01), and the clinical efficacy was superior apparently to that in control group (P < 0.01).

CONCLUSIONOn the basis of conventional treatment, acupuncture intervention at early stage can accelerate the recovery of brain arousal function in patients with severe craniocerebral injury.

Seasonal dynamics of total phenolics (TP), extractable condensed tannins (ECT), protein-bound condensed tannins (PBCT), fiber-bound condensed tannins (FBCT), total condensed tannins (TCT), and protein precipitation capacity (PPC) in young, mature and senescent branchlets of Casuarina equisetifolia were studied at Chishan Forestry Center of Dongshan County, Fujian Province, China. In addition, nitrogen contents of branchlets at the different developmental stages were also determined. The contents of TP and ECT, and PPC in young branchlets were significantly higher than those in mature and senescent branchlets through the season. However, PBCT contents were significantly higher in senescent branchlets than those in young and mature branchlets; FBCT fluctuated with season. Young branchlets had the highest N content, which decreased during branch maturity and senescence. The highest contents of TP and the lowest contents of TCT and N in young and mature branchlets were observed in summer. There was a significant negative correlation between TP and N contents. In contrast, TCT contents were positively correlated to N contents. Nutrient resorption during senescence and high TCT:N ratios in senescent branchlets are the important nutrient conservation strategies for C. equisetifolia.

BACKGROUNDPrevious studies showed that the prognostic factors for superficial transitional cell carcinoma of the bladder varied with the findings of different cohorts. Few multivariate analyses of prognostic factors for superficial bladder tumors have been reported in China and bladder preservation as a prognostic index of superficial bladder tumors is limited and scarce in Chinese patients. This study was conducted to analyze a group of risk factors for prognostic outcomes for patients with primary superficial transitional cell carcinoma of the bladder.

METHODSBetween January 1980 to December 2000, 198 patients [172 men and 26 women; mean age (52.98 +/- 11.28) years] with primary superficial transitional cell carcinoma who were pathologically classified as Ta or T1 in Hunan Provincial Tumor Hospital (Changsha, China) were enrolled in this study. Surgical methods included local resection and electric coagulation of bladder tumors, transurethral resection of bladder tumors and partial cystectomy. After initial surgical treatment, patients were followed through a cystoscopy every three months during the first two years and every six months thereafter in the design of retrospective cohort. Survival analysis was performed to analyze risk factors of the prognostic outcomes for transitional cell carcinoma of the bladder. Canonical correlation analysis was conducted to present and interpret synthetically the multi-correlation between all kinds of prognostic outcomes and risk factor in multiply dimensions.

RESULTSThe average follow-up period was (6.65 +/- 4.74) years. Assessments at three, five, and 10 years showed recurrence rates, respectively, of (28.32 +/- 3.45)%, (35.31 +/- 3.83)%, and (42.48 +/- 4.40)%; progression rates of (8.89 +/- 2.14)%, (15.16 +/- 2.94)%, and (23.88 +/- 4.19)%; bladder-preservation rates of (94.68 +/- 1.74)%, (93.87 +/- 1.91)%, and (91.51 +/- 2.49)%; metastasis rates of (8.25 +/- 2.05)%, (11.24 +/- 2.47)%, and (28.94 +/- 4.93)%; and cancer-related survival rates of (95.02 +/- 1.62)%, (90.70 +/- 2.45)%, and (77.14 +/- 4.88)%. The main risk factors for recurrence were histological grade, blood transfusion during surgery and the duration of symptoms. Progression was affected by blood transfusion during surgery, histological grade, the number of re-examinations, and the length of the recurrence-free period. Metastasis was associated with tumor multifocality, hydronephrosis, microscopic growth pattern, and the recurrence-free period. Cancer-related survival was influenced by microscopic growth pattern and the recurrence-free period. Bladder preservation involved only the recurrence-free period. The comprehensive results from canonical correlation analysis showed that the main prognostic outcomes were cancer-related survival, metastasis and progression respectively, while the dominate risk factors were histological grade, tumor multifocality and blood transfusion.

CONCLUSIONSThe risk factors were different for each prognostic outcome of transitional cell carcinoma of the bladder. This is helpful for predicting the prognosis of transitional cell carcinoma of the bladder and designing therapeutic and follow-up strategies for this cancer.
