Objective To study the alexithymia and personality characteristics in patients with somatoform disorders.Methods Totally 60 patients with somatoform disorders and 60 normal controls were tested with Toronto alexithymia scale (TAS) and Minnesota Multiphasic Personality Inventory (MMPI).Results The patients with somatization disorders showed alexithymia and personality base.The total and factor scores of TAS of study group((86.20 ± 11.15),(21.12 ± 3.28),(26.08 ± 3.86),(18.21 ± 4.69),(23.44 ±5.60)) were higher than controlled group((65.00 ± 10.12),(12.43 ±5.18),(15.64 ±5.57),(15.56 ±3.16),(18.71 ±4.30)) with significant difference (t =2.11-6.22,P =0.000-0.042).The MMPI scale scores of Hs (hypochondriasis),D (depression),Hy(hysteria),Men-Nancy(Mf),paranoid(Pa),psychotic(Pt) were higher in patients with somatoform disorders ((72.79 ± 10.50),(68.46 ± 13.63),(79.03 ± 12.12),(51.72 ± 7.74),(57.98 ± 10.60),(54.98 ±8.83)) than those in normal controls ((51.66 ± 10.11),(47.96 ±9.42),(51.47± 11.90),(43.66 ±8.77),(47.67 ± 6.69),(47.48 ±8.67)) with significant difference (t =2.56-6.86,P =0.000-0.015),especially the scale scores of Hy and Hs were the most significantly among those (T ＞ 70).There was close correlation between personality traits and alexithymia.Factor Ⅰ was positively related to depression,paranoid and psychotic,the relevancy was 0.454(P =0.023),0.405 (P=0.044),0.477 (P=0.016) respectively,besides Factor Ⅱ was also positively related to depression,and the relevancy was 0.437(P=0.029).Conclusion Patients with somatoform disorders have the alexithymia and the personality characteristics,and there are close relationship between them.

Objective To study the correlation of personality characteristics and plasma cortisol levels in the patients with generalized anxiety disorder.Methods According to Diagnostic and Statistical Manual of Mental Disorders (DSM-Ⅳ), 38 patients with generalized anxiety disorder and 39 normal controls were assessed with Hamilton anxiety scale (HAMA) , generalized anxiety disorder scale (GAD-7) , penn state worry questionnaire (PSWQ) , symptom checklist-90(SCL-90) and eysenck personality questionnaire (EPQ).Electrochemiluminescence was used to test plasma cortisol concentration.Results The EPQ-N score in the patients was significantly higher than that in normal controls(t=14.307, P＜0.01).Furthermore,N score in the patients showed a significantly positive correlation with HAMA total score, SCL-90 total score, somatization score, interpersonal sensitivity score, depression score and anxiety score (r=0.492-0.977, P＜0.01).Plasma cortisol levels in patients with generalized anxiety disorder((668.50±60.22) nmol/L) were significantly higher than those ((345.35±58.91) nmol/L) in normal controls (t=23.802, P＜0.01).Plasma cortisol concentrations displayed a significantly positive correlation with N score, GAD-7, PSWQ, HAMA total score, SCL-90 total score, somatization score, interpersonal sensitivity score, depression score, and anxiety score (r =0.501-0.995, P＜ 0.01).Conclusion Plasma cortisol levels in the patients with generalized anxiety disorder are higher than those in normal controls.Plasma cortisol levels are related to the mental health.Patients with generalized anxiety disorder tend to be neuroticism.

Objective To understand the guidance significance of sputum smear on the sputum culture by comparing the micro-scopic detection results of sputum smear with the sputum culture results in 227 cases.Methods 227 cases of sputum specimen were collected for observing the character and smear staining by microscopy.These specimens were divided into the class A,B,C and D according to the standards and simultaneously conducted the culture.The relationship between smear and culture was analyzed.Reˉ sults Among 227 cases of sputum specimen,158 cases were qualified and accounted for 69.60%,and 69 cases were unqualified and accounted for 30.40%.Potential pathogens were detected in 128 cases,the positive detection rate was 56.39%,the positive detec-tion rate of qualified sputum specimens was 70.39% and which of unqualified sputum specimens was 28.00%.The coincidence rate of qualified sputum specimen smear results and the culture results was 72.78%.The positive rate of cytophagic bacteria in the qual-ified sputum specimens was 11.72%,in which 14 cases of cytophagic bacteria were the qualified class A sputum specimens with the positive rate of 16.67% and 5 cases of cytophagic bacteria were the class B sputum specimens with the positive rate of 6.76 %. Conclusion The sputum smear microscopic detection can provide the important information for the diagnosis and treatment of re-spiratory infections and the sputum smear has the important guiding significance for sputum culture.

Objective To investigate whether sulfonylurea ( SU) increases the risk of stroke in patients with type 2 diabetes mellitus(T2DM). Methods A systemic meta-analysis including 17 random control trails(RCT) was performed to compare the risk of stroke between type 2 diabetic patients treated with SUs and comparators. Results 1 612 articles were retrieved, and finally 17 articles were included. Patients receiving SUs treatment had a higher relative risk of stroke (RR 1. 35, 95% CI 1. 13-1. 60) than those who received comparators. The I2 statistic for heterogeneity between 17 trails was 0. 0%(P=0. 687). No major asymmetry appeared in the funnel plot and Begg′adjusted rank correlation test(kendall′s score=22, P=0. 387). Conclusion The use of SUs may raise the risk of stroke which is already high in patients with T2DM.

Objective To investigate the role of NF-κB in apoptosis of immortalized neural progenitor cells (INPCs) . Methods INPCs were cultured in 6-well plates and were randomly divided into 5 groups ( n = 6 each) : group I was not transfected with any plasmid (group INPC); group Ⅱ was transfected with control plasmid (group INPC/CMV); group Ⅲ was transfected with plasmid RcCMV-p50 (group INPC/p50); group Ⅳ was transfected with plasmid RcCMV-p65 (group INPC/p65) and group V was transfected with plasmid RcCMV-p50 and RcCMV-p65 (group INPC/p50p65). Group INPC/CMV ( H ), INPC/p50 (Ⅲ) and INPC/p65 (Ⅳ) were screened by G418, and the positive clones were then cultured for 3-4 weeks. The transcription of p50 mRNA or p6S mRNA was detected by RT-PCR. The NF-κB activity was measured by luciferase reporter gene assay. The cell apoptosis was measured by annexin V/PI staining. In group INPC/p50p65 and group INPC/p65, the cultured positive clone was transiently transfected with plasmid RcCMV-p50. Two days after transfection, the same measurement was performed in group INPC/pS0p65 and the other groups. Results The expression of p50 mRNA was significantly increased in group INPC/p50 and INPC/p50p65 as compared with the other groups ( P < 0.05) . The expression of p65 mRNA, the NF-κB activity and the apoptotic rate were significantly increased in group INPC/p65 and INPC/p50p65 as compared with the other groups ( P < 0.05). Conclusion Enhanced NF-κB activity can increase immortalized neural progenitor cell apoptosis.

Structure of natural product-ursolic acid was modified for increasing its antitumor activity. Ursolic acid was acylated, esterified, hydrolized or oxidized to obtain target pentacyclic triterpenoid compounds with different substitutes. Sixteen derivatives of ursolic acid were designed and synthesized including eleven new compounds. Anti-tumor activities of ursolic acid and these derivatives against HeLa, SKOV3 and BGC-823 cells in vitro were investigated by MTT assay. The results indicated that compounds 7a and 8a were found to have stronger cell growth inhibitory than ursolic acid on HeLa cells and SKOV3 cells separately, and are worth to be intensively studied further.

Background and purpose: Solid papillary carcinoma (SPC) is an uncommon histological pattern accounting for <1% of breast carcinomas. It is a distinctive form of papillary carcinoma characterized by closely apposed expansile, cellar nodules. The present study aimed to investigate the clinicopathologic features, immunophenotype and prognosis of SPC of breast. Methods:We retrieved the data of 32 cases of SPC of the breast from pathology files, and determined the expressions of ER, PR, C-erbB-2, p63, Calponin, CK5/6, Ki-67, Syn and CgA by pathohistological observation and immunohistochemical examination. Results:All the patients were females with a mean age of 67.3 years. The clinical features were a palpable mass or bloody nipple discharge. The tumor was observed as a whitish-grey or yellowish-brown, lfeshy ifrm or soft, nodular circumscribed mass on gross examination. Microscopy showed solid and papillary area inside the capsule wall and that fine delicate fibrovascular septa were discovered amid the solid proliferation. The tumor cells were oval, polygonal, spindled or signet ring-like with abundant eosinophilic cytoplasm and contained mildly to moderately pleomorphic nuclei. Immunohistochemically, all tumor cells were strongly positive for ER and PR (++-+++), negative for C-erbB-2 and all cases were negative for CK5/6, p63 and Calponin in the cellular nodules. The positive expression rates of Syn and CgA were 68.8%and 78.2%, respectively. The average positive rate of Ki-67 in tumor cells was 7.5%(2%-20%). Twenty-seven patients were available for follow-up examination from 6 to 84 months and 25 patients were alive and disease free. One patient had tumor recurrence, and was alive after reoperation. Another patient died of the tumor metastasis. Conclusion:SPC is predominantly found in elderly females with distinctive pathological features and immunophenotype. SPC often carries an indolent clinical behavior, and even if accompanied by inifltration, very rare cases have recurrence and metastasis after resection, so its prognosis is better.

Objective To evaluate the blood-saving effect of combination of hemocoagulase artox for injection and tranexamic acid (TXA) in patients undergoing off-pump coronary artery bypass grafting (OPCABG).Methods Eighty ASA Ⅱ patients (NYHA Ⅰ or Ⅱ),aged 50-70 yr,weighing 50-100 kg,scheduled for elective OPCABG,were randomly divided into 4 groups (n =20 each):control group (group C),hemocoagulase atrox for injection group (group H,n =20),TXA group (group T) and hemocoagulase atrox for injection + ·TXA group (group HT).Hemocoagulase atrox 0.04 U/kg (the highest dose 4 U) was injected at 20 min before skin incision,and additional hemocoagulase atrox 2 U was given every 2 h starting from 15 min after administration of protamine until the end of operation in group H.TXA 20 mg/kg was injected intravenously at skin incision,followed by a continuous infusion of TXA at 10 mg· kg-1 · h-1 until the end of operation in group T.Hemocoagulase atrox and TXA were given as the method described in groups H and T.Venous blood samples were taken from the central vein before operation,at the end of operation,and 24 h after operation to determine the plasma D-Dimer concentration.The amount of blood loss,allogeneic red blood cells and plasma infused during operation,volume of drainage during 0-6 and 6-24 h after operation,total volume of drainage and volume of allogeneic blood transfused during operation were recorded.The deep vein thrombosis was recorded.Results Compared with group C,the amount of blood loss during operation was significantly decreased in groups T and HT,and the allogeneic red blood cells and plasma infused during operation,and volume of drainage during 0-6 and 6-24 h after operation,and total volume of drainage were significantly decreased in groups H,T and HT (P ＜ 0.05).Compared with groups H and T,the allogeneic red blood cells and plasma infused during operation,and volume of drainage during 0-6 and 6-24 h after operation,and total volume of drainage were significantly decreased in group HT (P ＜ 0.05).No deep vein thrombosis was observed in the 4 groups.Conclusion The combination of hemocoagulase artox for injection and TXA provides better blood-saving effect than either alone for the patients undergoing OPCABG without increasing the risk for thrombosis.
