The trial group was treated with cognitive behavior therapy; the control group was treated with routine care. All cases in two groups were assessed with Zung's Self-rating Anxiety Scale (SAS) before and after treatment.Results After cognitive behavior therapy, the SAS scores of cases of the trial group were significantly lower than that before treatment and that of cases of the control group after treatment ( P<0.01).Conclusion Cognitive behavior therapy can improve anxiety symptom of patients with schizophrenia in recovery stage.

Objective To investigate the therapeutic value of Shuxuetong injection in patients with acute coronary syndrome(ACS).Methods 89 ACS patients were divided randomly into two groups: control group(n =44) and experimental group(n=45).The conventional therapy was used in the control group while Shuxuetong was added in the experimental group.The course of treatment was two weeks.Thromboxane B2(TXB2) and 6-keto-prosta-glandin F1a (6-K-PGF1a) were detected by radio-immunity before and after therapy.Homocysteine were tested by corpuscle enzyme linked immunosorbent assay.Results TXB2 was obviously lower in the experimental group [(554.2±303.2) ng/L] and the control group [(737.2±299.3 ) ng/L ] after treatment than that before treatment (P<0.05).Homocysteine was obviously lower in the experimental group [(10.42±2.99 )μmol/L ] and the control group [(16.39±2.29) μmol/L ] after treatment than that before treatment (P < 0.05 ).6-K-PGF1a was obviously higher in the experimental group[(328.4±99.6) ng/L] and the control group[ (234.5±96.2) ng/L] after treat-ment than that before treatment (P<0.05).TXB2 and homoeysteine in the experimental group were obviously lower than those in the control group after treatment(P<0.05). 6-K-PGF1 a in the experimental group was obviously high-er than those in the control group after treatment (P<0.05).Conclusion Shuxuetong injection could degrade the level of TXB2 and HCY, increase the level of PGF1 a and improve the balance of TXB2/PGF1a, so Shuxuetong is ef-fective in treating acute coronary syndrome.

Objective To study the influence of Nictinamide on the endotheline(ET-1)in patienta with pulmonary arterial hypertension(PAH).Methods 66 cases of PAH were divided randomly into two groups (n=33for each):the Nictinamide treatment group and the control group.The changes of endotheline were compared before and after treatment.Results After treatment serum endotheline was significantly lower in the treatment group(P＜0.01),but there was no difference in the control group before and aftertreatment(P＞0.05).The significant difference was observed between treatment group and control group(P＜0.01).Conclusion Nictinamide will reduce the level of endothellne and confers some degree therapeutic and preventive value for PAH.

10 mg?kg -1?d -1? 5 d. The inhibitory rate of ZD1694( 0.001- 1 000 mmol?L -1)on SGC-7901 cells were increased in concentration and time-dependent manner. The cell numbers in G_0-G_1 phase in SGC-7901 cells were raised by ZD1694 as well. CONCLUSION: ZD1694 can take obvious antitumor effects on S180-bearing mice. The antitumor rate of ZD1694 is in a dose-dependent manner, and it is higher when the total dosage is administered in one day than that the total dosage was divided into 5 consecutive days. ZD1694 can inhibit the growth of SGC-7901 cells and block the cells in G_1 phase in vitro.

Depression and insomnia are intimately related. Depressed patients usually manifest sleep discontinuity and early awakening, reduced or no slow wave sleep (SWS) and shortened latency of rapid eye movement (REM) sleep. These sleep abnormalities are very similar to those caused by over activated hypothalamic-pituitary-adrenal (HPA) axis with stress. Therefore, the animal models developed by post-traumatic stress disorder or chronic unpredictable mild stress could be used to evaluate drugs which have effects of both anti-depression and improvement of sleep quality, and to provide a more reliable platform for further studis on the mechanisms of depression and accompanied insomnia. This review mainly focuses on the typical features of sleep disturbance of depression, possible pathophysiological mechanisms, establishment of animal stress models and analysis of their abnormal sleep characteristics.

BACKGROUND: Studies have shown that mild hypertension and hypothermia both offer cerebral protection against focal cerebral ischemia,and their possible synergistic effect may provide even better neuroprotective effects.OBJECTIVE: To investigate the mechanism of cerebral protection by induced hypertension combined with mild hypothermia against focal cerebral ischemia and reperfusion, through observation of the changes in the infarct volume and blood-brain barrier(BBB) in rats.DESIGN: A randomized controlled experimental study based on experimental animals.SETTING: The departments of neurology of two university hospitals and department of dermatology in a municipal hospital.MATERIALS: The study was carried out in the Laboratory of Department of Neurology, Union Hospital Affiliated to Tongji Medical College, Huazhong University of Science and Technology and Laboratory of Department of Neurology, People' s Hospital of Wuhan University from March to July 2001. Sixty-four Wistar rats weighing 180 to 230 g were purchased from the Experimental Animal Center of People' s Hospital of Wuhan University.INTERVENTIONS: Sixty-four rats were randomly divided into control group, hypertension group, mild hypothermia group, and combined therapy group, each group consisting of 16 rats. Reperfusion was initiated after a 3-hour focal cerebral ischemia of the 16 rats, and at 2 hour during the ischemia, the rats in the hypertension and mild hypothermia group were treated with hypertension for 3 hours and mild hypothermia, respectively, and those in the combined therapy group received both treatment. The rats in the control group received no treatments for ischemia and reperfusion. Twenty-four hours later, all rats were killed for examination.MAIN OUTCOME MEASURES: The scores of neurological deficits, infarct volume and degree of BBB damage.RESULTS: The scores for neurological deficits, infarct size and volume of Even' s blue staining were 2. 12 ±0. 54, (17.65 ±4.78)%, and(56.63± 10.70) mm3, respectively, in hypertension group, and 2. 14 ±0.69,(16. 21 ± 3.79)%, and(53.52 ± 8.44) mm3 in mild hypothermia group,and 1.78 ±0. 61, (11, 31 ±3.64)%, and 38.45 ±5.25 mm3 in combined therapy group, which were all decreased significantly as compared with the control group[2.70 ±0. 64, (28.34 ±4. 13)%, and(94.87 ± 15.34) mm3].The combined therapy group had the smallest infarct size and volume of Even's blue staining among the three treatment groups( P ＜ 0.05).CONCLUSION: Hypertension and mild hypothermia may reduce the infarct volume and alleviate BBB damage during focal cerebral ischemia and reperfusion in rats, and the effects of combined treatment are more obvious.

Objective To summarize the lung HRCT findings of lung Langerhans cell histiocytosis (LCH) in children. Methods A total of 54 children with lung LCH pathologically proved in our institute from September 2006 to December 2014 were retrospectively reviewed. Patients were subdivided into two subgroups, diffuse type (n=29) and localized type (n=25). In addition, 32 children with LCH but without pulmonary infiltration were selected as control group. HRCT findings of 54 LCH with lung involvement were reviewed and analyzed for distribution pattern. The age of onset, illness duration and pulmonary function were compared between the lung LCH group and the control group. The differences of HRCT findings in LCH patients between diffuse type and localized type were compared with χ2 test. The differences on the onset age, illness duration and pulmonary function between the LCH group with lung involvement and control group were compared with non-parametric test(Mann-Whitney U Test). The differences of pulmonary function between the LCH group with lung involvement and control group were compared with Fisher exact probability test. Results The signs of pulmonary LCH on HRCT included lobular hyperinflation (n=26), interlobular septa thickening (n=11), cystic lesions (n=11), ground?glass opacity (n=10), nodules (n=9), and centrilobular nodules (n=6). The signs presented in 21, 8, 7, 9, 4 and 6 cases in diffuse type group respectively and 5, 3, 4, 1, 5, 0 in localized type group. Among them, lobular hyperinflation, ground?glass opacity and centrilobular nodules were more prevalent in the diffuse group. The difference was statistically significant (χ2=14.77,2.01,0.55,4.84,0.06 and 3.91, P<0.05). The onset age of LCH group with lung involvement was younger than the other (Z=-2.40, P<0.05). However, there was no statistically significant difference in the illness duration (Z=-1.46, P>0.05) and pulmonary function between two groups (P>0.05). Conclusions Lobular hyperinflation, ground glass opacity and centrilobular nodules are the most common manifestations in LCH patients with lung involvement and the distribution is mostly diffuse. Nodules, cystic lesions and interlobular septa thickening may exist. Several signs may coexist simultaneously. Younger children with LCH are more vulnerable to lung involvement.

Objective:To investigate the effect of prison police's job burnout on their life satisfaction and the role of psychological detachment between them.Methods:Questionnaire survey was conducted among 253 prison policemen in Henan Province with the Maslach Burnout Inventory-General Survey (MBI-GS,including emotional exhaustion,cynicism,and reduced personal accomplishment),Satisfaction with Life Scale (SWLS) and Psychological Detachment Questionnaire (PDQ).Results:The MBI-GS total scores and the scores of its three dimensions were negatively correlated with SWLS scores (r ＝-0.41,-0.38,-0.36,-0.21,Ps ＜0.001),PDQ scores were negatively correlated with MBI-GS total scores and emotional exhaustion scores (r ＝-0.21,-0.31,Ps ＜ 0.001),but positively correlated with SWLS scores (r ＝ 0.22,P ＜ 0.001).Psychological detachment played a moderating role between job burnout and life satisfaction (β ＝ 0.58,P ＜ 0.001).Conclusion:It suggests that prison police's job burnout may reduce their life satisfaction,and psychological detachment can moderate the influence of job burnout on life satisfaction.

Aim To detect the effects of cetuximab combined with adriamycin on the proliferation and ap-optosis of triple-negative breast cancer cells.Methods Cell viability was evaluated by MTT assay.The cell apoptosis was analyzed by flow cytometry with propidi-um iodide staining.JC-1 staining was used to deter-mine mitochondrial membrane potential.The expres-sions of glucose regulated protein78 (GRP-78),Bcl-2 and Caspase-3 were measured with Western blot.Re-sults MTT assay showed that cetuximab had inhibi-tion effect on the breast cancer cell MDA-MB-231 growth,and the effect was related to concentration of drug.The inhibition effect of adriamycin on MDA-MB-231 had remarkabe relationship with time and concen-tration.When combined with each other,they could re-markably increase inhibition effect.The viability of cells in combination group for 1 2 h,24 h,48 h,sig-nificantly lower than that in cetuximab or adriamycin group (P <0.05 or P <0.01 ).Apoptosis results showed that cell apoptosis was significantly increased when cetuximab combined with adriamycin,reached (43.93 ±3.59)% for 24 h,had remarkably statistical significance compared to cetuximab or adriamycin
group (P <0.01 ).JC-1 staining indicated that cetux-imab or adriamycin could reduce the mitochondrial membrane potential,but the reduction effect was more remarkable in the combination group.Western blot re-vealed that cetuximab could reduce the expression of GRP-78 and Bcl-2,and increased the expression of Caspase-3 and its activity.The expressions of Bcl-2, Caspase-3 had no significant change in adriamycin group,but GRP-78 was increased.In combination group,the expression of GRP-78 and Bcl-2 was signifi-cantly decreased,but Caspase-3 was increased nota-blely compared to adriamycin group.Conclusions The combination of cetuximab and adriamycin enhances the inhibition effect on the triple-negative breast cancer MDA-MB-231 cells,and increases cell apoptosis.The mechanism may be that cetuximab reduces the endo-plasmic reticulum stress level,then activates the mito-chondrial pathways by decreasing the expression of Bcl-2,reducing the mitochondrial membrane potential,and promoting cell apoptosis.
