Methods Sixty-six (29 male, 37 female, 34.0±9.5 years old) patients with major depression were recruited before the treatment. Dysfunctional Beliefs and Attitudes about Sleep (DBAS) questionnaire, Pittsburgh Sleep Quality Index (PSQI), Hamilton Depression Rating Scale (HDRS), and Hamilton Anxiety Scale (HAMA) were assessed before and after a 4-week antidepressant treatment. Results After the 4-week antidepressant treatment, depressive and anxiety symptoms were alleviated significantly, whereas sleep disturbance still persisted. And sleep quality was closely related with problematic sleep beliefs after the treatment.Conclusion Some evidences are provided for cognitive behavioral therapy during antidepressant therapy, and the therapy should be matched with problematic beliefs and attitudes.

Aim Telomerase is highly expression in most tumor cells, and it is an ideal target for cancer molecular targeting therapy. It has been proved that wogonin effectively inhibits telomerase activity and tumor cell growth in vitro. The study was to explore the inhibitory effect of wogonin on the growth of tumor and telomerase activity of implanted human ovarian cancer cell line SKOV3 in nude mice. Methods Nude mice with implanted human ovarian cancer cells SKOV3 were randomly divided into five groups, viz. the high dose group of Wogonin(600 mg?kg-1),low dose group of Wogonin(300 mg?kg-1),normal control group, cisplatin therapy group(3 mg?kg-1), and combined therapy group(cisplatin plus wogonin).The weight of nude mice and the volume of tumor were regularly measured. DNA、RNA and protein were extracted from the tumor tissue. The length of telomere was examined by Southern blot. The expression of telomerase hTERT gene was detected by RT-PCR. The telomerase activity was examined by TRAP-PCR-silver staining. Results The wogonin significantly inhibit the growth of tumor when compared with controlled group.The inhibitory rate of high dose group and low dose group were 56.67% (P=0.002) and 38.10%(P=0.019), respectively. The inhibition rate of cisplatin therapy group was 50.83%(P=0.004). The suppress rate of combined group reached 66.9% and higher than any single therapy(P=0.002). The length of telomere in different concentration groups of wogonin was the same as that in the control group.Wogonin inhibited the expression of telomerase gene hTERT and telomerase activity. The inhibition is related to the dose of wogonin. Conclusion Wogonin suppresses the growth and telomerase activity of tumor. The inhibitory effect is related to the dose of wogonin. Combination of wogonin and cisplatin increase the inhibitory rate in nude mice tumor.

BACKGROUND: At present, international classification of diseases by WHO, cerebrovascular disease classification used in China and TOAST classification used abroad are all based on patho-physiology. There is no report about human cerebral infarction by magnetic imaging types in Beijing and other areas.OBJECTIVE: To analyze retrospectively the subtype distribution of acute cerebral infarction of patients in Beijing by magnetic resonance imaging in order to make Beijing patients with acute ischemic stroke receive more exact and individualized treatment.DESIGN: Retrospective case study.SETTING: Department of Neurology, General Hospital of Beijing Military Area Command of Chinese PLA.PARTICIPANTS: The study was carried out in General Hospital of Beijing Military Area Command of Chinese PLA, Beijing Sino-Japan Friendship Hospital, Beijing Chaoyang Hospital, Beijing Naval General Hospital and Beijing Jishuitan Hospital between January and December 2004. Totally 602 inpatients with ischemic stroke who received treatment in each hospital were recruited. They were 352 male and 250 female with average age of (65.6±10.2) years.METHODS: The 602 patients with acute ischemic cerebral stroke who received the treatment in the 5 hospitals from Dongcheng, Xicheng,Chaoyang and Haidian districts in Beijing were recruited in the study. According to results of magnetic resonance imaging of brain, the maximal infarction area were determined. The patients were classified as: large infarction: over 1 lobe of brain, ＞ 5.0 cm in diameter; moderate infarction: less than 1 lobe of brain, 3.1-5.0 cm; small infarction: 1.6-3.0 cm; lacunar infarction, ＜ 1.5 cm.MAIN OUTCOME MEASURES: Constitution ratio of MRI classification of patients in each groupRESULTS: Totally 602 patients with ischemic stroke participanted in final result analysis. Among the patients with acute cerebral infarction of 5 hospitals in Beijing, 280 (46.5%) suffered from lacunar infarction, 299(38.1%) from small infarction, 57 (9.4%) from moderate infarction, and 36 (6%) from large infarction. There were significant differences between lacunar infarction and other types (P ＜ 0.01).CONCLUSION: Acute cerebral infarction of patients of Beijing mostly occurs in the type of lacunar infarction. It suggests that small arterial diseases are the major disease type of ischemic stroke in Beijing. This MRI classfication can be used for early classification, treatment guidance, evaluation and prognosis of acute ischemic cerebral stroke.

Objective To find the clinical and histopathological predictive factors for lateral lymph node ( LN ) metastasis in thyroid papillary microcarcinoma( PTMC ).Methods From January 2007 to December 2010,141 patients with PTMC underwent central and lateral LN dissections were enrolled in the study.The data from the cases were analyzed retrospectively to determine the predictive factors for lateral LN metastasis.Results Among the aforementioned cases,37 cases ( 26.2％ ) were PTMC with the presence of multifocality,24 ( 16.9％ ) Hashimoto thyroiditis,84 ( 59.6％ ) central LN metastasis,56 ( 39.7％ ) lateral LN metastasis.Multifocality,central LN metastasis,underlying Hashimoto thyroiditis,and upper pole location were significantly related to lateral LN metastasis in univariate analysis( P＜0.05 ).These four factors were also found to be independent predictive factors for lateral LN metastasis in multivariate analysis( P＜0.05 ).9(6.4％ ) of there patients were found to show skip metastasis in which there was lateral LN metastasis but no central LN metastasis.The upper pole location was statistically significantly associated with skip metastasis.Conclusions Patients with multifocality,central LN metastasis,underlying Hashimoto thyroiditis,and upper pole location should be paid more attention to the status of lateral LN.Skip metastasis occurs in a minority of patients with PTMC.Even if there is no central LN metastasis,patients with upper pole lesion should be searched carefully for the lateral cervical LN metastasis.
