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: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.

[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.
5.CT diagnosis and differential diagnosis of traumatic subdural effusion in elderly patients: a report of 52 cases
Chinese Journal of Neuromedicine 2010;09(11):1154-1157
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.

OBJECTIVETo investigate the dynamic changes of neurofilament contents in rat's spinal cord induced by 2, 5-hexanedione (2, 5-HD), and explore the molecular mechanism of n-hexane neuropathy.
METHODSMale Wistar rats were administered at a dosage of 400 mg/kg/day 2, 5-HD for 2, 4 and 8 weeks respectively. HD-induced neurological defects were detected and quantified using gait score, and the relative lev-els of NF-H, NF-M, and NF-L in spinal cords of rats were determined by Western Blotting.
RESULTSExposure to 2, 5-HD produced progressive gait abnormalities, which suggested that the rat model of 2, 5-HD-induced neurotoxicity was established successfully. Western-Blotting results showed that NFs content in spinal cord demonstrated a progressive decline as the intoxication continued. In the supernatant fraction, compared to the controls, NF-H con-tent decreased by 15.7%, 57.0%, and 58.0% respectively after 2, 4, and 8-week treatment with 2, 5-HD (P < 0.01); accordingly, NF-M decreased by 36.0%, 61.3%, and 65.2% respectively (P < 0.01); NF-L decreased by 20.8%, 43.9%, and 44.3% respectively (P < 0.01). In the pellet fraction, the contents of NF-H in groups of 4 and 8 weeks' exposure to HD decreased by 35.6% and 43.2%, respectively (P < 0.01), and those of NF-L decreased by 26.4% and 42.1%, respectively (P < 0.01) when compared to the control. Further-more, NF-M contents in groups of 2, 4 and 8 weeks' exposure decreased by 23.3%, 33.9%, and 63.7% respectively (P < 0.01). The NFs level in spinal cords was highly correlated with gait abnormality of treated rats as the intoxication went on. Multiple correlation coefficients of NF-H, NF-M, and NF-L content with gait score of HD-treated rat were 0.8912, 0.9282 and 0.8981 (P < 0.01) respectively.
CONCLUSIONThe declines of NFs are high-ly related to neurobehavioral abnormality of 2, 5-HD-treated animals, and involved in the development of n-hexane neuropathy.
