Objective To analyze CT characteristics of spherical pneumonia in order to differentiate it from other lesions especially lung cancer. Methods The CT and X-ray film of 25 cases diagnosed clinically as spherical pneumonia were analysed retrospectively.Results CT features of 25 patients were summarized as follow : ⑴Lesions were usually located in the posterior lung fields.(2)The central part of the lesions showed high density, while periphery part of lesion were low in density and blurred. (3)The bilateral margin of lesions were straight, and the lesions appeared square or triangular in shape. ⑷Margins of the lesions may be irregular and blurred. ⑸There were marked pleural reaction around the lesions and some times pleura diffusely thickening occurred. ⑹Vascular marking around the lesions were exaggerated increase and thickened, nevertheless they were not stiff. Conclusion CT is valuable in diagnosing and differential diagnosing spherical pneumonia.

Objective To explore the relationship between aggressive behavior with thyroid hormone or cortisol and in schizophrenic patients. Methods According to the past violence history and modified overt aggression scale( MOAS) weighted total scores,108 schizophrenic patients were divided into aggressive group ( n=69) and non-aggressive group( n=39) . Positive and Negative Syndrome Scale ( PANSS) total scores, serum thyroid hormone levels and cortisol concentration were compared between the two groups before and af-ter 2,4 weeks treatment. And correlations of PANSS and sub-scales scores,thyroid hormone levels and corti-sol concentration with MOAS weighted total scores and subscales scores were analyzed before these patients receiving treatment. Results Before treatment,total scores of PANSS,positive symptoms and general psy-chopathology scores in aggressive group((94.19±12.71),(23.77±4.94),(52.61±6.45))were higher than that in non-aggressive group ((83.26±11.21),(21.36±7.10),(45.49±6.84)) and these differences were significant(P<0.05). But the difference of PANSS total scores after 2,4 weeks treatment between the two groups was not significant (P>0. 05 ) . Free thyroxine ( FT4 ) level of aggressive group ( ( 14. 41 ± 3. 58 ) pmol/L) was higher than that of non-aggressive group ((12.95±2.66)pmol/L) before treatment and the difference was significant(P<0.05) . Meanwhile,there was no significant differences between the two groups in thyrotropic-stimulating hormone(TSH),free triiodothyronine(FT3),total triiodothyronine(TT3) and total thyroxine( TT4) levels( all P>0.05) . After 2 or 4 weeks treatment,the differences between the two groups in TSH,FT3,FT4,TT3,TT4 levels were not significant(P>0.05). The differences between the two groups of cortisol concentration were not significant before and after 2,4 weeks treatment(P>0.05) . MOAS weighted to-tal scores were positively correlated with PANSS total scores,negative symptoms scores,general psychopathol-ogy scores and level of FT4,and their r values were 0.471,0.204,0.531,0.239(all P<0.05). Verbal aggres-sion was positively correlated with PANSS total scores,positive symptoms scores and general psychopathology scores,and their r values were 0.213,0.215,0.292(P<0.05). Auto-aggression was positively correlated with PANSS total scores and general psychopathology scores,and their r values were 0.278,0.382(P<0.05) . Psy-chical aggression was positively correlated with PANSS total scores,negative symptoms scores,general psy-chopathology scores and level of FT4,and their r values were 0.361,0.193,0.338,0.276(P<0.05). Conclusion The total scores of PANSS,positive symptoms,general psychopathology scores,level of FT4 and their variances can reflect severity of aggression and predict aggressive behavior in schizophrenic patients. Concen-tration of cortisol is not associated with aggressive behavior and can not be used as a predictor of aggressive behavior in schizophrenic patients.

Objective: To examine the correlation between paliperidone plasma concentration and clinical efficacy in the patients with schizophrenia. Methods:Totally 50 schizophrenia patients were treated by paliperidone. The plasma concentration of paliperidone was monitored by RP-HPLC at the weekend of the 2 nd, 4 th and 6 th week, the clinical efficacy was evaluated using the positive and negative syndrome scale ( PANSS) , and the correlation between paliperidone plasma concentration and clinical efficacy was analyzed. Results:The mean plasma concentration of paliperidone was (31. 89 ± 17. 36) ng·ml-1 at the weekend of the 6th week, and no cor-relation was found between paliperidone plasma concentration and the clinical efficacy (r=0. 146,P=0. 074). Paliperidone plasma concentration in 12 patients with adverse drug reactions (ADR) was higher than that in the patients without ADR [(45. 87 ± 19. 21)ng ·ml-1 vs (27. 06 ± 11. 13) ng·ml-1, P <0. 01]. Conclusion: Paliperidone plasma concentration shows significant individual differences. With the increase of paliperidone plasma concentration, clinical efficacy isn't necessarily improved, while the incidence of ADR may be increased. Therefore, the monitoring of paliperidone plasma concentration is recommended to optimize the therapeutic reg-imen.

Objective To investigate the role of adiponectin in the cell growth,apoptosis and cell cycle of the T47D breast cancer cell line and to find out the pathogenesis of breast cancer.Methods The cell cycle of the T47D cell line was examined by flow cytometry and apoptosis was detected by Annexin Ⅴ-FITC/PI stain method.Results T47D cell line adhered to the cell wall by single layer culture,irregular shape,and cell amounts increased over time.(1) Though different concentrations of adiponectin had a certain action on restraining the cell in different times,there were no significance(P＞0.05).(2)After treated with 500 ng/ml and 2000 ng/ml adiponectin on T47D cells for 48 h,the proportion of G0/G1 phase was (91.07±0.63)％,(91.60±0.98)％,respectively.Compared with the control group (85.31±1.07)％,the difference was statistically significant(F=29.277,P=0.011).But the difference of S and G2/M phase was not statistically significant(P＞0.05).(3) The difference of early apoptosis rate among control group,500 ng/ml and 2000 ng/ml adiponectin was not statistically significant(P＞0.05).The same concentration of adiponectin could not induce the early apoptosis and total apoptosis of T47D cells(P＞0.05,respectively).Conclusion The low adiponectin level may be the risk factor of breast cancer.The adiponectin may regulate the distribution of cell cycle.It may induce G0/G1 phase arrest of T47D cells and reduce the DNA synthesis.It suggested that adiponectin may serve as a protective factor of breast cancer development.

Objective To study the clinical values and relativity of serum levels of NSE and ProGRP (P31-98) in patients with small-cell lung cancer. Methods Serum levels of NSE and ProGRP (31-98) was measured by ELISA in 159 patients with small cell lung cancer(SCLC), 99 patients with benign lung diseases, and 100 healthy subjects, 141 SCLC patients before and after treatment were also measured. Results The medians of NSE and ProGRP (31-98) was 21.33 μg/L and 323.70 pg/ml in patients with SCLC, 4.24 μg/L and 11.94 pg/ml in patients with benign lung diseases, 5.82 μg/L and 8.54 pg/ml in healthy subjects respectively,significantly increased in patients with SCLC as compared to that of the other two groups (P ＜0.01).Given the cut-off levels of 10.35 pg/L for NSE and 47.98 pg/ml for ProGRP(31-98), the sensitivity of diagnosis in SCLC was 71.1% and 88.7 %, respectively.The combination sensitivity and specificity of NSE and ProGRP(31-98)was 95.6 % and 96.8 %. The medians of NSE in SCLC patients with extensive and limited disease was 14.75 μg/L and 34.10 μg/L, the sensitivity was 51.14 % and 93.44 %, respectively; ProGRP (31-98) in the two groups was 143.14 pg/ml and 1061.14 pg/ml, 80.61% and 98.61%, respectively.In SCLC patients with remission after treatment the levels of NSE and ProGRP31-98 was significantly lower than that before treatment, but the levels without remission had no significantly change. There was significant relationship between NSE and ProGRP(31-98) in serum levels of patients with SCLC (r =0.379, P ＜0.01).Conclusion The serum levels of NSE and ProGRP (31-98) in patients are both increased, there are a significant relationship.But ProGRP(31-98) is a more specific and sensitive marker than NSE for the diagnosis of SCLC.The combination of the two markers can improve positive rate and validity.
