Objective:To explore the effect of group psychotherapy on damage of theory of mind (TOM) in patients with early-onset schizophrenia.Methods:Totally 60 patients with early-onset schizophrenia were included and divided into the intervention group (n ＝ 30) and the health education group (n ＝ 30).The patients in the intervention group were offered 10 twice a week 2-hour sessions of group psychotherapy,and those in the control were offered group health education twice a week.All participants completed baseline measures and post-intervention measures with the Eye Emotion Recognition and Theory of mind Picture-sequencing Task (TOM-PST).Results:Totally 23 patients in the intervention group and 29 patients in the health education group finished the post-intervention measures.After 5-week intervention,subscores of sad and fear and total score of emotion recognition,total score of TOM-PST,understanding first order error belief,second order error belief,third order error belief,sense of reality,detecting fraud compared to baseline had statistically significant difference in intervention group.In health education group,subscores of joy emotion recognition,understanding first order error belief,third order error belief,total score of TOM-PST compared to baseline had statstically significant difference.The patients with group psychotherapy got higher scores of total score of TOM-PST and understanding second order error belief and third order error belief than the health education group after 5-week intervention (P ＜ 0.05).Conclusion:This study suggests the group psychotherapy could partially improve theory of mind with early-onset schizophrenia,and promote the recovery of social cognition.

Objective To investigate the value of platelet, serum sodium and serum creatinine levels in the prognosis of patients with liver failure. Methods The clinical data of 155 patients with liver failure were retrospectively analyzed, and the patients were divided into improvement survival group (87 cases) and deterioration died group (68 cases) according to the prognosis. The hospitalization time of every patient was divided into 4 roughly equal time period, and observed at 5 points of time:T1-T5. The levels and abnormal rates of platelet, serum sodium and serum creatinine were compared. Results The T3 - T5 serum creatinine levels in deterioration died group were significantly higher than those in improvement survival group: (102.14 ± 75.67) μmol/L vs. (78.21 ± 26.68) μmol/L, (116.45 ± 110.64)μmol/L vs. (78.77 ± 29.25) μmol/L, (161.43 ± 153.23) μmol/L vs. (76.40 ± 27.26) μmol/L, and the T1 - T5 serum sodium and platelet levels were significantly lower than those in improvement survival group:(135.05 ± 6.24) mmol/L vs. (137.52 ± 5.26) mmol/L, (137.01 ± 4.99) mmol/L vs. (139.00 ± 3.89) mmol/L, (134.80 ± 16.74) mmol/L vs. (139.15 ± 3.77) mmol/L, (134.40 ± 11.69) mmol/L vs. (138.30 ± 8.75) mmol/L, (133.30 ± 8.93) mmol/L vs. (139.01 ± 9.10) mmol/L, and (122.46 ± 72.59) × 109/L vs. (149.70 ± 71.70) ×109/L, (110.18 ± 65.10) × 109/L vs. (152.09 ± 82.79) ×109/L, (107.32 ± 70.49) ×109/L vs. (169.32 ± 100.65) ×109/L, (97.06 ± 58.15) ×109/L vs. (183.57 ± 112.68) ×109/L, (94.66 ± 57.00) × 109/L vs. (191.36 ± 118.64) ×109/L, and there were statistical differences (P<0.05). The abnormal rates of T3-T5 serum creatinine, T2 - T5 serum sodium and T1 - T5 platelet in deterioration died group were significantly higher than those in improvement survival group, the serum creatinine: 22.06%(15/68) vs. 6.90% (6/87), 27.49% (19/68) vs. 8.05% (7/87) and 42.65% (29/68) vs. 10.34% (9/87), the serum sodium: 32.35% (22/68) vs. 13.79% (12/87), 39.71% (27/68) vs. 14.94% (13/87), 48.53% (33/68) vs. 12.64%(11/87) and 60.29%(41/68) vs. 11.49%(10/87), the platelet:45.59%(31/68) vs. 21.84%(19/87), 55.88% (38/68) vs. 24.14% (21/87), 54.41% (37/68) vs. 25.29% (22/87), 55.88% (38/68) vs. 21.84%(19/87) and 61.76% (42/68) vs. 20.69% (18/87), and there were statistical differences (P<0.05). Abnormal rate of platelet was highest in each time point. Conclusions In the course of pathological changes in deterioration and dead patients, the platelet is the first and most easily affected compare with serum sodium and serum creatinine; the platelet may be a sensitive marker for predicting clinical outcome in patients with liver failure.

Objectives To isolate the cardiogenic fraction, which can enhance cardiogenic differentiation of bone marrow-derived mesenchymal stem cells(MSC)from Geum iaponicum.The therapeutic effeet of the isolated cardiogenic fraction was further tested in a rat myocardial infaretion (MI)model.Method Bioassay guided fractionation method was used for the isolation of the cardiogenic fraction,named as heart repair fraction(HRF).MI was induced by a permanent ligation of left anterior descending coronary artery.The rats exhibiting similarly decreased values of left ventricle ejection fraction(LVEF) and fraction shortening(LVFS)were used.The rats in test group(n=10)were subject to HRF treatment(20 mg·kg-1·d-1)through gastric gavage daily for 4 weeks.Water alone(2 ml/d) was given through gastric gavage to rats in the control group(n=10).The cardiac function was assessed by echocardiography at different time points.Masson trichrome staining was used for evaluation of the infarct size.Morphological and immunohistochemical studies were performed to investigate the HRF mediated myocardial regeneration.Results LVEF(66.2%±6.9%)and LVFS(46.8%±5.8%)were significantly increased two weeks post HRF treatment compared with the values(LVEF:55.7%±6.0%and LVES:36.4%±5.2%)in control rats(a11 P<0.01).The improved heart function was further restored 4 weeks post HRF treatment(P<0.01).Furthermore,the treatment of acute MI with this HRF significantly reduced the infarct size(19.0%±6.1%)compared with that(31.1%±8.6%)in control rats(P<0.01).Substantial regeneration of cardiomyoeytes in infarcted region of the HRF treated heart was also observed that replaced a considerable part of the infarcted heart tissues resulting in remarkable reduction of the infarct size.Conclusion The properties of this HRF isolated from Geum japonicum in stimulating substantial regeneration of myocardium in infarct region with consequently improved cardiac function appear to be new and represent a new approach for the treatment of MI.

Objective: To study the distribution of levofloxacin in the serum and ascites in patients with cirrhosis and to evaluate its efficacy in treatment of patients with spontaneous bacterial peritonitis(SBP). Methods:（1）Concentration of levofloxacin in the serum and ascites was detected with HPLC in 7 patients with cirrhosis at different time (in the serum: 0.5, 1, 1.5, 2 and 12 h;in the ascites:2, 4, 6 and 12 h). （2）The effects of levofloxacin were observed in treatment of 30 patients with SBP. Results:（1） Levofloxacin was determined in serum and ascites of patients with cirrhosis, whose concentration depended on the duration after oral administration. In serum: tmax was 1.5 h and cmax was (3.913±1.388) μg/ml. In ascites: tmax was 6.0 h and cmax was (2.520±1.213) μg/ml. The levels decreased gradually after reaching peak concentration, then stabilized from 12 h.（2）The symptoms and signs were significantly improved in patients with SBP treated with the levofloxacin. Conclusion: After the oral administration, levofloxacin can both distribute in serum and ascites, and it is efficient in the treatment of the patients with SBP.

OBJECTIVETo investigate if the Ribbond polyethylene fiber has the effect of reinforcing polymethyl methacylate.

METHODS28 specimens were fabricated and divided into 3 groups: group of chemical-cured PMMA, group of chemical-cured PMMA reinforced by stainless steel wire and group of chemical-cured PMMA reinforced by Ribbond polyethylene fiber. A three-point bending test was used to measure the flexural strength and flexural modulus of specimens. Then the data were analyzed with a one-way analysis of variance.

RESULTSThe flexural strength of chemical-cured PMMA group was (51.383 +/- 2.761) MPa, the flexural modulus was (1791.2 +/- 113.760) MPa; The flexural strength of stainless steel wire reinforced group was (58.725 +/- 1.218) MPa, the flexural modulus was (2092.76 +/- 120.28) MPa; The flexural strength of Ribbond polyethylene fiber reinforced group was (80.975 +/- 2.58) MPa, the flexural modulus was (2866.53 +/- 107.51) MPa. The one-way analysis of variance showed that the results were significant (P < 0.001). Newman-Keuls method showed that the differences among all groups were significant (P < 0.05).

CONCLUSIONThe Ribbond polyethylene fiber can raise the flexural strength and flexural modulu of polymethyl methacylate.

Objective To investigate the biomechanical effects of interbody cage height on cervical spine during anterior cervical discectomy and fusion (ACDF) surgery,so as to provide references for selection of interbody cage.Metheds The finite element model of normal cervical spine (C2-7) was built and validated,and the cages with different height (5,6,7,8 mm) were implanted into C5-6 disc (cage 5,6,7,8 model).All the models were loaded with pure moment of 1.5 N · m to produce flexion,extension,lateral bending and axial rotation motions on cervical spine,and the effects of cage height on range of motion (ROM),facet joint stress,intervertebral pressure in cervical spine were investigated.Results The intervertebral angle at the fusion segment increased by 0.68° with per 1 mm-increase in height.The ROM in C5-6 after cage implantation was smaller than 0.44°.The influence of cage height on ROM in C4-5 was greater than that in C6-7,and the changes of ROM in non-fusion segments were smaller than 7.3％.The cage height variation had a smaller impact on the facet joint stress and intervertebral pressure.The stresses in the capsular ligament,cage and screw-plate system increased gradually with the increase of cage height,and the stresses in cage 6,7,8 models were much higher than those in cage 5 model.Conclusions For patients who need implanting fusion cage,the cage height should be 0-1 mm greater than the original intervertebral space height.

OBJECTIVETo evaluate the relationship between the clinical stages of nasopharyngeal carcinoma (NPC) and Epstein-Barr virus (EBV) antibodies Rta/IgG, EBNA1/IgA, VCA/IgA and EA/IgA.

METHODSSerum samples obtained from 211 untreated patients with NPC categorized by the project of 92' stage were examined for the presence of the EBV antibodies Rta/IgG and EBNA1/IgA by enzyme-linked immnunosorbent assay (ELISA) and for VCA/IgA and EA/IgA by immunoenzymatic assay. The positive rates and antibody levels in the NPC patients in different TNM stages and clinical stages were analyzed statistically.

RESULTSNo significant difference in Rta/IgG rA value was found in the NPC patients in different TNM or clinical stages (P>0.05). The EBNA1/IgA rA value was significantly lower in stage T1, N0, and clinical stage I than in the other corresponding T stages, N stages and other clinical stage (P<0.05). The antibody titers of VCA/IgA and EA/IgA differed significantly between the N stages and the clinical stages (P<0.05).

CONCLUSIONThe expression of EBV Rta/IgG is not associated with NPC stage. The expression of EBNA1/IgA is relatively low in early NPC. The antibody level of VCA/IgA and EA/IgA are significantly correlated to the degree of neck lymph node metastasis, and might be helpful to classify the clinical stages of NPC.
