Objective To evaluate the clinical effect of group cognitive behavioral therapy on blood glucose levels,anxiety and depression in patients with type2 diabetes mellitus.Methods Ninety three patients with type 2 diabetes mellitus were recruited and randomly divided into intervention group (n =48) and control group (n =45).Both groups received diabetes health education,patients in intervention group received additional group cognitive behavioral therapy.The glucose tolerance,glycosylated hemoglobin A1c were measured; the HAMA(Hamilton Anxiety Scale)scores,HAMD(Hamilton Depression Scale)scores and CSQ (Coping Styles Questionnaire) scores in patients were analyzed before and 6 months after treatment.Results After 6-month treatment the fasting blood glucose (6.33 mmol/L vs.5.94 mmol/L),1 h postprandial plasma glucose(12.40 mmol/L vs.11.46 rmool/L),2 h postprandial plasma glucose (10.24 mmol/L vs.9.13 mmol/L),A1 c (6.31％ vs.6.07％) in intervention group were decreased significantly,compared to baseline values (all P ＜ 0.05).The HAMA total score (9.98 vs.8.14),somatic anxiety (3.98 vs.3.48),psychic anxiety(6.00 vs.4.67),HAMD total score(10.74 vs.6.93),anxiety somatic(5.02 vs.3.26),block(2.24 vs.1.38)and sleep disorders(2.40 vs.1.40)in intervention group were all decreased significantly(P ＜ 0.01 or 0.05).There were significant differences in HAMA total score (8.14 vs.9.15),HAMD total score(6.93 vs.9.33),anxiety somatic(3.26 vs.4.38),block(1.38 vs.1.98)and sleep disorders(1.40 vs.2.03)between the intervention group and control group(P ＜ 0.01 or 0.05).And the negative coping style scores in intervention group was also lower than that of the baseline (26.74 vs..29.43).Conclusion The group cognitive behavioral therapy combined with diabetes health education for patients with type 2 diabetes mellitus may improve the glucose metabolism and depression and anxiety status of patients.

Objective To analyze the etiology of cerebral ischemic complications occurring in perioperative period of interventional therapy for intracranial aneurysms,and to discuss its prevention and treatment.Methods From January 2011 to March 2015,a total of 1106 patients with intracranial aneurysms underwent interventional therapy at the First Affiliated Hospital of Zhengzhou University,China.Among the 1106 patients,48 patients developed cerebral ischemic complications;their clinical data and the imaging materials were retrospectively analyzed.The factors associated with complications,the effective therapeutic scheme and the clinical preventive methods were discussed.Three months after the treatment,the recovery of neurological function was assessed with modified Rankin Scale (mRS).Results The causes of ischemic complications were,in order of decreasing frequency,cerebral vasospasm/unable elimination of microemboli (n=19),thrombus (n=16),impaired blood flow of adjacent perforating or distal vascular branches caused by embolization (n=6),intra-procedural hypotension (n=4) and cerebral edema (n=3).Combined treatments,including integrated anticoagulation,anti-platelet aggregation,anti-vasospasm,medication of elevating blood pressure,endovascular intervention,etc.were adopted.The patients were followed up for 3 months.Thirty-four patients (70.8％) obtained a mRS of ≤2 (no serious sequelae),and mRS＞2 (poor prognosis) was seen in 14 patients (29.2％).Conclusion The etiology of cerebral ischemia occurring during interventional treatment of intracranial aneurysms is complicated.It is necessary to take useful measures such as individualized anticoagulation,anti-platelet aggregation,anti-vasospasm,etc.during perioperative period of interventional therapy.The procedure-related complications can be effectively treated with interventional therapy and reliably prevented by careful and skilled surgical manipulation.

Leaves of Chrysanthemum morifolium were potential medicinal resource. The present study aims to estimate the main bioactive components: total flavonoids (TF), galuteolin (GA), quercitrin (QU), chlorogenic acid (CA) and 3 ,5-O-caffeoylquinic acid ( CQ), which were considered to be the main effective components, in leaves of C. morfolium cultivars in China. The TF content was estimated hy UV-VIS spectrophotometry, while GA, QU, CA, and CQ were quantitatively determined by HPLC. The highest TF content (7. 13% w/w) was found in cultivar Wan Cong (Shexian county). Cultivar Da Bo ( Bozhou county) had the highest GA content (33. 45 mg - g-1); Cultivar Hong Xin (Sheyang county) contained the highest QU content (29.25 mg · g(-1)); Cultivar Chang Ban (Sheyang county) had the highest CA content (13.14 mg ·(-1)). The maximum CQ content (7.35 mg · g(-1)) was observed in culti- r Da Yang ( Tongxiang county). Different cultivars of C. morfolium had significant difference in components, but the leaf and capitulum of C. morifolium. were found to possess similar chemical compositions. The high content of bioactive components in several cultivars suggested the potential utilization of C. morifolium leaves.

Paracetamol was used as a model drug in this study to investigate the synergetic effects of lipid coating and beta-cyclodextrin (beta-CD) inclusion for masking the bitter taste of poorly soluble drugs. To control the concentration as low as possible of the free drug which produced a bitter taste, a kinetic model was established to calculate the drug distribution theoretically among the free drug in medium, lipid coated particles and molecular inclusion on the basis of the preparation and characterization of the lipid microspheres, so as to select the proper amount of beta-CD. Finally, the synergetic drug delivery systems were prepared and characterized by 1H nuclear magnetic resonance (1H NMR), molecular simulation and the electronic tongue. As a result, the drug release rate constant (k) of the lipid microspheres coated with octadecanol was determined as 0.001 270 s(-1). Then, the synergetic drug delivery systems were prepared with the ratio of 6.74 : 1 (w/w) for beta-CD and paracetamol. The chemical shift values for the fingerprint peaks of paracetamol all increased and hydrogen bonds were formed between the oxygen on the phenolic hydroxyl group, the nitrogen on the imino in paracetamol and the hydrogens on the hydroxyl groups in beta-CD. The results tested by the electronic tongue indicated that the paracetamol, lipid microspheres, beta-CD inclusion and their mixture showed different taste characteristics, with the bitterness order of the synergetic drug delivery systems approximately lipid microspheres < beta-CD inclusion < paracetamol, which confirmed the synergetic taste masking effects of lipid coating and beta-CD molecular inclusion. In summary, the synergetic taste masking was jointly achieved through the retard of the drug release by the lipid coating and the inclusion of the free paracetamol by beta-CD through hydrogen bonds.

OBJECTIVETo investigate the value of computer-assisted slide-screening system (ThinPrep imaging system, TIS) in the diagnosis of cervical Thinprep smears.

METHODSA total of 19 600 ThinPrep smears were collected, including 9800 slides by TIS-assisted screening from September 2011 to March 2012 and 9800 slides by manual screening from September 2010 to April 2011 as control. The detection rates of abnormal cells and common microbial infection by the different screening methods were compared. With histopathological diagnosis of colposcopic biopsy as the gold standard, the screening efficiency and correlation of cytologic diagnosis among different screening methods were analyzed.

RESULTSCompared with manual screening, the detection rate of abnormal cells in 9800 cases by TIS-assisted screen was increased from 5.4% (525/9800) to 6.8% (665/9800), mainly in the categories of ASCUS and LSIL (P < 0.05). TIS had a higher accordance rate between cytologic diagnosis and histopathological diagnosis in the NILM and ASCUS than that by manual screening. False-negative rate of finding abnormal cells by TIS decreased from 8.5% (17/200) to 0.7% (2/289, P < 0.01) with an increased sensitivity compared to manual screening, although the specificity was similar. Both TIS and manual screening had advantages and disadvantages respectively in the detection of microbial organisms. TIS improved screening efficiency by 50%.

CONCLUSIONTIS improves not only the screening efficiency but also the detection of abnormal cells with a reduced false negativity, and it therefore has a broad application prospect.
