Objective To investigate the influence of psychosocial factors to emotional disorder of tumor patients. Methods 76 patients with tumor and other 76 patients with tumor were including. All the patients themselves completed once through the following questionnaires: Symptom Check List (SCL-90),Self-rating Anxiety Scale (SAS), Self-rating Depression Scale (SDS), Life Event Scale (LES). However, Hamilton Depression rating scale (HAMD) and Hamilton Anxiety rating Scale (HAMA) were measured by the researchers. Results The occurrence rate of depression and anxiety in tumor patients was clearly higher than that of the control group (P<0.01), while the negative life event increased. Conclusion The occurrence rate of the emotional disorder among tumor patients is clearly higher than the control group, which may be related with the negative life event.

OBJECTIVETo investigate the malondialdehyde (MDA) level and paraoxonase-1 (PON-1) activity in the serum and seminal plasma of infertile men with chronic viral hepatitis and their influence on the semen parameters of the patients.

METHODSWe collected serum and semen samples from 42 infertile men, 45 infertile males with chronic viral hepatitis, and 50 healthy fertile men as controls. We measured the MDA level in the serum and seminal plasma by spectrophotometry, detected the PON-1 activity by spectrophotometry, and determined the sperm DNA fragmentation index (DFI) by acridine orange fluorescence staining.

RESULTSThe MDA level was significantly higher but the PON-1 activity remarkably lower in the serum and seminal plasma of the infertile males with chronic viral hepatitis than in the healthy controls and infertile patients (P <0.01 or P <0.05). Total sperm motility and sperm survival rate were significantly lower while the sperm DFI markedly higher in the former than in the latter two groups (P <0.01 or P <0.05). No statistically significant difference was found among the three groups in sperm concentration (P >0.05). The WBC counts in the semen of the infertile and infertile with chronic viral hepatitis groups were significantly higher than that in the health controls (P <0.05). The MDA level and PON-1 activity in the seminal plasma were positively correlated with those in the serum in the infertile males with chronic viral hepatitis (r=0.57 or 0.48, P <0.01).

CONCLUSIONVirus-induced chronic active hepatitis enhances oxidative stress in the reproductive system, aggravates sperm damage, and affects sperm quality parameters.

Objective To analyse the clinicopathological features of primary small intestine lymphoma(PSIL), and explore the relationship between clinical stage,histological findings,therapeutic modality and prognosis. Methods The clinical data of 34 cases of PSIL were collected,the pathohistological features and results of immunohistochemical examinations were obtained,and the follow-up findings were adopted for comprehensive analysis. Results Among these 34 cases of PSIL,abdominal pain or discomfort,gastrointestinal bleeding and abdominal mass were the predominant symptoms.PSIL mainly involved ileum,especially the bottom of ileum and ileocecal area.Among the 26 patients with follow-up for more than one year,the 1-year survival rate was significantly higher in patients without tumor perforation than those with tumor perforation(76.2% vs 20.0%)(P

Objective Establish rabbit VX2 soft tissue tumor model,and treat it with percutaneous ethanol injection(PEI)under the guidance of magnetic resonance imaging.Make ready for the therapeutic evaluation with functional magnetic resonance imaging. Methods Fifteen healthy New Zealand white rabbits were included in this study.0.2 mL tumor tissue suspensions were injected into the rabbits’posterior limb.14 days later,all rabbits were underwent conventional MRI examination.PET were performed to all the tumors under the guidance of MRI in the next day of the examination.T2 WI was used as guidance and monitoring means.MR com-patible puncture needle with lateral hole was stabed into the lesion center,and inj ected anhydrous ethanol according to the volume of tumors’diameter (1 mL/cm )slowly.the tumors signal characteristics,morphological feature and pathological feature were ob-served pre and post-operation.Results All of the 1 5 rabbits were established soft tissue tumor model successfully;the success rate is 100%.The tumors were oval or round,3-4 cm in diam.MRI scanning showed low signal on T1 WI and high signal on T2 WI be-fore PEI.PEI was performed to all the tumors under the guidance of MR successfully with 3.5 mL ethanol injected into the tumors in average.T2 WI could monitor the ethanol in dispersion and distribution within the tumors clearly.Histologically,tumors were composed of large,uniform,oval/round cells arranged in solid nests which was intensive in the periphery of tumors.Necrosis tissue was apparent in the center of the tumors.10 days after operation,most tissue in the periphery of tumors was coagulative necrosis , only a few tumor cells left.Ranges of necrosis in the tumors center were obviously increased compared with pre-operation.Conclusion Rabbit VX2 tumor of soft tissue model is suitable for the therapeutic evaluation of tumor .It is an animal model which has the characteristic of simple to operate and high rate of suc-cessful.MR T2 WI can monitor the ethanol in dispersion and distribution within the tumors clearly.It is a good guidance and monitoring imaging method of tumor ablation.

Objective To study the antigenicity of human thyrotropin receptor(hTSHR)amino terminus (amino acid 29～280)and its association with Graves' disease.Methods Total thyroid RNA was prepared from human normal thyroid tissue.RNA was then reversely transcripted and cDNA was subjected to PCR amplification.PCR product was cloned into pcDNA3.1 and the recombinant plasmid was named pcDNA3.1/hTSHR188～940bp. Balb/c mice were immunized with peDNA3.1/hTSHR188～940bp. The levels of serum thyroxin,anti-TSHR antibody(TRAb)and thyroid stimulating antibody(TSAb)were measured,and the pathological changes of thyroid tissue were also observed.Results A 753 bp fragment encoding hTSHR ectodomain amino end was obtained after PCR amplification.Confirmed by Hind Ⅲ restriction enzyme digestion and DNA sequencing,pcDNA3.1/hTSHR188～940bphad been constructed successfully,with the correct sequence and direction of hTSHR188～940bp.In the Balb/c mice treated with pcDNA3.1/hTSHR188～940bp,elevated TRAb in week 6(0.148±0.018)were observed compared with those at week o(0.106±0.006,P＜0.01),and kept a higher level till week 10(0.134±0.011,P＜0.01).T4 and TSAb index values were significantly increased in week 10.Serum T4 concentration increased from(41.02±7.97)μg/L in week 0 to(62.20±12.77)μg/L in week 10(P＜0.01);TSAb index values rose from 0.864±0.076 at week 0 to 1.392±0.615(P＜0.01).Thyroid pathological examination showed that proliferated thyroid follicular epithelial cells and foll icular eapacity increased.Inflammatory cells were occasionally found.Conclusions There are antigen epitopes in hTSHR ectodomain amino acid 29～280,which can stimulate the production of TSAb.And the latter induces hyperthyroidism and Graves' disease like manifestations.It suggests that hTSHR ectodomain amino acid 29～280 is closely associated with Graves' disease,and maybe one of important etiological factors leading to the disease.

Objective To investigate the MRI and echocardiography manifestations of noncompaction of ventricular myocardium(NVM)and assess the role of MRI in the diagnosis of NVM by comparing it with echocardiography.Methods Fourteen cases of NVM diagnosed by echocardiography were examined with MRI,including scanning of black-blood sequences,double inversion recovery fast spin echo (DIRFSE)and triple inversion recovery fast spin echo(TIRFSE),and white blood sequence:fast imaging employ steady state acquisition(FIESTA).Scanning plane includes short axis view,four-chamber view and long axis view.Results Both MRI and echocardiography displayed involvement of left ventricles in thirteen cases and involvement of double ventricles in one case.Apexes of heart and the intermedius are commonly affected.MRI showed 54 segments and echocardiography showed 53 segments affected,and there is no significant difference between the capability of MRI and echocardiography(P=1.000).The affected myocardium consisted of two layers:subendoeardial noncompacted myocardium and epicardial compacted myocardium,and the ratio measurement of N/C by MRI was 3.37?0.89 and it was 3.19?0.82 by echocardiography.Noncompacted myocardium was characterized by prominent and excessive myocardial trabeculations and deep intratrabecular recesses,in which the blood flow was communicated with the ventricle.One case was complicated with ventricular aneurysm,and coronary arteriography was performed with unremarkable findings.One case underwent heart transplantation because of progressive heart failure, Gross findings demonstrated prominent muscular trabeculations with deep intratrabecular recesses,which coincided well with MRI findings.Conclusion The MRI manifestation of NVM is characteristic,and MRI with multiple series and planes is helpful in the diagnose of NVM.Compared with echoeardiography,MRI could display the pathological cardiac muscle more clearly,because of its high soft-tissue resolution and spatial resolution.

OBJECTIVEThis study aimed to explore the scene-trait coping style of military rescuers in Wenchuan earthquake in an effort to provide scientific evidences for mental intervention program for Chinese military personnel.

METHODSBy cluster sampling, a total of 151 military rescuers and 331 control servicemen were administered the military personnel scene-trait coping style scale (MPSTCSS).

RESULTSAll active coping factor scores, and passive coping factor scores of affection, health and economy in the rescuer group were significantly higher than those in control group (P < 0.05). The 21-above age subgroup, the 3-year plus service subgroup, and the officer subgroup had significantly higher active coping factor scores on military tasks, military experience and personal development than those of the 21-below age subgroup, 3-year minus service subgroup and the soldier subgroup, respectively (P < 0.05 or P < 0.01).

CONCLUSIONThe earthquake relief servicemen can cope with stressful situations better than control group by taking active coping style. The officers, servicemen older than 21 years, and servicemen with more service duration than 3 years could usually take active coping style.

Objective To observe the Th17, IL-17 and Tr cells equilibrium state as well as their changes of HIV infected or AIDS suffered patients in one-year HAART treatment. Methods Select 33 HIV/AIDS patients received HAART treatment while 33 healthy volunteers as controls. Flow cytometry was used to analyze Th17 and Tr cells in venous blood at the time of pre-therapy, 6th, 12th month when IL-17 levels in serum are tested by ELISA. Results The ratio of Th17 cells in CD4 cells in HIV/AIDS patients and volunteers were (1.20±0.37)%, (2.50±1.03)%, (3.70±1.56)%, (4.70±1.43)%, respectively; The ratio of Tr cells were (9.16±3.33)%, (7.19±2.91)%, (5.53±1.88)%, (4.43±0.97)%, respectively; The levels of IL-17 in serum were (5.3±2.5) pg/ml, (7.7±2.4) pg/ml, (10.4±3.1) pg/ml, (17.7±6.6) pg/ml respectively. The Th17 cells' level was positively correlative with the amount of CD4 cells, negatively correlate with the count of viral load. However, the Tr cells level is positively correlative with the count of viral load, negatively relate to the quantity of CD4 cells. Conclusion HIV could make IL-17, Th17 cells and Tr cells lost their balance, but the immune equilibrium state may gradually recover after HAART treatment. Which indicates the IL-17, Th17 cells and Treg cells may play an important role in the pathogenesis of AIDS, and they are likely to be the effective indexes to observe the progress of AIDS and the treatment effect of highly active antiretroviral therapy(HAART).

Objective To study the prevalence of mental disorders among the Chinese youths aged 15-34 years,in rural areas and to identify risk factors related to suicide.Methods A consecutive sampling strategy was used for suicidal cases in 16 randomly selected counties in Hunan,Liaoning,and Shandong provinces.Between 2005 and 2008,a total of 392 suicide cases were recruited with 416 community controls at the same age range,selected from the same areas one family member together with one close friend of each suicidal case were interviewed,using the psychological autopsy (PA) method.The same method with structured instruments was performed on the two informants for each control in the same community.SCID was used for the diagnosis of mental disease.Results 48.0％ of the suicides were diagnosed as having at least one mental disorder episode,in comparison with only 3.8％ among the controls.It was found that mental disorder was the most important risk factor for the Chinese young suicide cases in the rural areas.Conclusion As seen in the Western countries,mental disorder had also been the number one correlate on suicidal cases in China,with the difference as other social and psychological factors might have played relatively more important roles in China.
