Recently diverse magnetic resonance imaging technology is used in glioma grading,which based on the theory of Gaussian distribution.Diffusion kurtosis imaging emerges as an extension of DWI and DTI,which could reflect the real and actual hydron non-Gaussion distribution of tumor and peritumoral microenvironment.Displaying the correlation with immunohistochemical label Ki-67,DKI convinces more scholars inland and abroad with its practicability.

As an important nucleus of basal ganglia, globus pallidus was concerned to involve in the neural mechanism of Parkins's disease (PD). Previous studies of PD patients and animal model indicate that neurotransmitters and receptors are changed in globus pallidus neurons, the balance between inhibition and excitation is broken in the output nuclei of basal ganglia, and globus pallidus neurons display bursting and oscillatory discharge, the synchronous tendency of neighboring neurons enhances. These neurophysiological changes are associated with PD symptoms, such as bradykinesia, rigidity and tremor, which reflects that globus pallidus plays an important role in the process of PD. In the present paper, the recent advances in pathophysiology in globus pallidus, its clinical application in treatment of Parkinson's disease, and the study direction in the future are reviewed.

Objective To observe the clinical efficacy of acupuncture in treating Oxycodone hydrochloride-induced constipation in cancer pain patients.Method Sixty cancer pain patients with Oxycodone hydrochloride-induced constipation were randomized into a treatment group and a control group, 30 cases in each group. The treatment group was intervened by acupuncture, while the control group was by oral administration of lactulose oral solution. The therapeutic efficacies were compared after 2-week treatment, and the quality of life was evaluated before and after treatment.Result The total effective rate was 90.0% in the treatment group versus 73.3% in the control group, and the difference was statistically significant (P<0.05). The Karnofsky Performance Status (KPS) score was significantly changed in the treatment group after intervention (P<0.05). There was a significant difference in comparing the KPS score between the two groups after treatment (P<0.05).Conclusion Acupuncture can produce a significant efficacy in treating Oxycodone hydrochloride-induced constipation, and also improve the patients’ quality of life.

Objective To observe the influence of specific short hairpin siRNA targeting EGFR gene on apoptosis of human ovarian cancer Skov-3 cells in vitro. Methods A plasmid of a short hairpin siRNA targeting EGFR was constructed, and it was transfeeted into Skov-3 cell line by lipofectamine 2000. Human ovarian carcinoma cells of the line Skov-3 were cultured and divided into 3 groups: control group; non-specific group, transfected with non-specific plasmid vector; and specific group, transfected with specific small hairpin RNA expression vector. The expression of EGFR mRNA and protein were examined by RT-PCR and immunocytochemistry, Flow cytometry (FCM) was adopted to analyze quantitatively apoptotic cells in each group. Results After transfection of pshRNA-EGFR, mRNA and protein levels of EGFR gene in Skov-3 cells were obviously reduced. Flow cytometry analysis revealed that apoptosis could be induced in Skov-3 cells line transfected with pshRNA-EGFR in a time-dependent manner, no obvious apoptosis were detected in control group and non-specific group. Conclusion The plasmid expressive vector target at EGFR in our study is capable of suppressing EGFR expression of human ovarian cancer Skov-3 cells and inducing apoptosis, which provide a new way for the gene therapy of human ovarian cancer.

Objective To investigate the clinicopathologic characteristics and prognosis of triple negative breast cancer patients. Methods A retrospective analysis was performed for 1042 primary breast cancer patients admitted in the First Affiliated Hospital of Nanjing Medical University from January 2003 to December 2009.All breast cancer patients were categorized into three subgroups by immunohistochemistry:ERBB2 +,HR +/ERBB2 - and triple negative. Results Of 1042 breast cancer patients recruited,183 patients were in triple negative group.The rate of larger tumors ( greater than 2 cm in diameter) and grade Ⅲ in triple negative patients was higher than that in ERBB2 + and HR +/ERBB2 - patients (P ＜0.01 ).The positive rate of p53 status in ERBB2 + patients was higher than that in triple negative and HR +/ERBB2- patients (P ＜ 0.01 ).No significant differences were observed in other clinical variables.In survival analysis,more bone metastases were observed in HR +/ERBB2 - patients than in ERBB2 + and triple negative patients (P =0.006).However,no significant difference was observed in visceral metastases among the subgroups.There were significantly different recurrence-free survivals (RFS) among the three subgroups throughout the follow-up period ( P =0.029),the 5-year RFS of ERBB2 + was 80.3％,which was the worst in three groups. Conclusions Triple negative patients had higher rate of larger tumors (greater than 2 cm in diameter) and grade Ⅲ than that in ERBB2 + and HR +/ERBB2 - patients,while its 5-year RFS was higher than ERBB2 + patients.

Objective DryLab software was used to assist high performance liquid chromatography (HPLC) method to test and isolate six Cytochrome P450 (CYP450) probe substrates.Methods Six CYP450 probe substrates were selected and the right HPLC method was developed and validated with the assistance of DryLab software.Results The new HPLC method with the assistance of DryLab software could test and isolate six probe substrates with degrees of isolation more than 2.00. The correlation coefficients (R> 0.999 8) indicated high linear correlation between the concentrations and the peak areas among six probe substrates. Recovery studies showed good results for all the probe substrat from 86.38% to 110.29%. And therelative standard deviation (RSD) ranged from 1.69% to 3.80% with its intra-day and inter-day precision ranging from 0.42% to 2.01%, and 1.36% to 2.29%, respectively.Conclusions The developed HPLC method with the assistance of DryLab could test and isolate six probe substrates with shortertime than the HPLC method alone.

Objective To investigate the prevalence of anxiety and depression among the persons with disabilities in Shanghai and the factors related to them. Methods From November to December, 2014, 731 persons with disabilities were consecutively enrolled in this cross-sectional study. They were assessed with Self-rating Anxiety Scale (SAS) and the Self-rating Depression Scale (SDS). Binary Logistic regression analysis was employed to reveal potential related factors of anxiety and depression. Results The prevalence rates of anxiety and depression among the disabled in Shanghai were 9.58%and 8.48%, respectively. The duration (OR=0.967, P<0.05) and severity (OR<1, P<0.05) of disability were associated with depression, whereas retiral (OR=2.047, P<0.05), living alone or in care unit (OR=3.073, P<0.01) and duration of disability (OR=0.956, P<0.01) were associated with anxiety. Conclusion The frequency of anxiety and depression is mild among the persons with disabilities in Shanghai, and a special intervention is needed.

This study was aimed to find the fragmentation pathways of Schisandrin B using the Discovery Studio by electrospray ionization mass spectrometry (ESI-MSn). The first and multi-stage mass spectrum diagrams were obtained. The results showed that mass spectrometry fragments of Schisandrin B was analyzed under the positive mode, the cracking rings are mainly occurred, and free radicals such as H2O, -CH3 and -OCH3 were lost. It was concluded that this study enriched the mass spectral decomposition, and provided basis for the study on chemical constituents of lignan compounds.
