Objective: The aim of the research was to test the applicability of Chinese Meaning in Life Questionnaire (C-MLQ) and its reliability and validity in college students. Methods: C-MLQ and a parcel of scales were administered to 531 college students from three universities in China. Exploratory Factor Analysis (EFA) and confirmatory factor analysis (CFA) were employed to check the construct validity. Results: Firstly, the internal consistency of the two subscales were qualified, the coefficient alpha of two subscales were 0.85 and 0.82 respectively; test-retest reliability were 0.74 and 0.76 respectively; secondly, compared with original scales, the construct of C-MLQ also had two factors, the item factor loadings ranging from 0.61 to 0.78 on the factor it belonged to. Thirdly, the correlations of C-MLQ and criterion measurement were 0.025 to 0.637. Finally, there were no gender difference in the scores of two subscales. Conclusion: The CMILQ has good reliability and validity and it can be used to assess individual meaning in life.

Transsexuals are specific humans who abandon their traditionally functional reproduction.However they may wish to have a child in the new-gender identity.At present in China,assisted reproductive technology(ART) should be limited to those female-to-male transsexuals with a female partner.The assisted reproductive institutions should keep the information for transsexuals confidential in the whole treatment procedure.In some cases,we could appeal to the ART ethics committee for support.Before sex reassignment surgery(SRS),the candidate transsexuals could preserve their fertility by cryo-storing germ cells,tissues and organs for future reproductive usage.

Objective To investigate the application of serum soluble interleukin-2 receptor(sIL-2R)and soluble tumor necrosis factor receptor Ⅱ (sTNFR Ⅱ) in extrapulmonary organ involvement sarcoidosis.Methods Of 28 cases with sarcoidosis which were in active period,12 cases were in extrapulmonary organ involvement subgroup,16 cases were in pure pulmonary lesions subgroup.Serum sIL-2R and sTNFR Ⅱ of the two groups were detected by enzyme linked immunosorbent assay and compared.Results The expression level of sIL-2R in extrapulmonary organ involvement subgroup was (1.60 ± 0.80) μg/L,significantly higher than that of pure pulmonary lesions group,and there was significant difference((1.00±0.29)μg/L,t =2.764,P＜0.05);and the expression level of sTNFR Ⅱ in extrapulmonary organ involvement subgroup was (1.09 ± 0.24) μg/L,significantly higher than that of pure pulmonary lesions group,and the difference between the two groups was statistically significant((0.85±0.29) μg/L,t =2.183,P＜0.05).Conclusion The expression level of peripheral blood serum sIL-2R and sTNFR Ⅱ may serve as the important indexes to judge the extrapulmonary organ involvement sarcoidosis.

It is generally considered that various regulatory activities between genes are contained in the gene expression datasets. Therefore, the underlying gene regulatory relationship and the biologically useful information can be found by modeling the gene regulatory network from the gene expression data. In our study, two unsupervised matrix factorization methods, independent component analysis (ICA) and nonnegative matrix factorization (NMF), were proposed to identify significant genes and model the regulatory network using the microarray gene expression data of Alzheimer's disease (AD). By bio-molecular analyzing of the pathways, the differences between ICA and NMF have been explored and the fact, which the inflammatory reaction is one of the main pathological mechanisms of AD, is also emphasized. It was demonstrated that our study gave a novel and valuable method for the research of early detection and pathological mechanism, biomarkers' findings of AD.

Objective: To investigate the effect about the treatment in asynchronous cerebral arterial thrombosis of cerebral circulation therapeutic equipment with disease function rehabilitation and the trigger factor of stroke and cerebral blood flow in 108 cases. Methods:Treatment group on the basis of conventional drug treatment plus brain circulation function therapeutic apparatus (KJ-3000-a) treatment in patients with stroke in different disease period. Using the neural function defect score and controllable risk factors of stroke and TCD determination of internal carotid artery and vertebral artery blood flow changes in evaluation of cerebral circulation function therapeutic equipment therapy in treatment group and control group is effective and feasible. Results:Different stages of stroke treatment group after treatment of acute phase of the neural function defect score in the control group (t=-13.26, P<0.05), and factors caused troke such as blood pressure and cholesterol leels also declined significantly than control group (t=7.39, t=7.75, P<0.05), cerebral blood flow between treatment group and the control group after treatment mainly reflected in the increased blood flow of part of left and right internal carotid artery and Vertebral Artery ,as Vd, Vs and Vm. Conclusion:Against the illness severity stroke with drug therapy on the basis of brain circulation function therapeutic instrument to stimulate rehabilitation treatment is convenient, economic, safe, effective, can be applied to stroke periods with high blood pressure, cholesterol levels, but acute stage used the best, after post-stroke patients vital center smoothly, can take early used cerebral circulation function therapeutic equipment for rehabilitation.

Objective] To observe the clinical efficacy of Agkistrodon in treating Sjogren's syndrome. [Methods] 52 patients were randomly divided into two groups: Treatment of 26 patients taking Agkistrodon and the basic prescription medicine(YIQIYANGYINQUYU drugs); 26 patients in the control received the basic prescription medicine. The clinical symptoms,the disease activity score of SSDAI,the score of TCM symptom and life quality and the index of serology were recorded in this clinical observation. [Results] The treatment group had better results of immune function than the control group after treatment, in particular had a substantial decrease in IgG. In addition, the clinical symptoms, the disease activity score of SSDAI, the score of TCM symptom and life quality were improved. [Conclusion] Agkistrodon has significantly immunosuppressive effects on the patients with Sjogren's syndrome , thus improving the patients' condition,the standard of living and the quality of life.

Objective To compare the different expression patterns of survivin and caspase-3 between the larger part and the smaller part of the dissymmetric enlarged prostates in BPH patients, and to clarify the role of apoptosis in BPH etiology. Methods BPH tissues from 25 patients were embedded in paraffin. The specimens constituted of two prostate parts from each patient. One part was from the larger enlarged gland and the other was from the smaller enlarged counterpart. 50 paraf-fin blocks were cut into sections and stained with survivin and caspase-3 polyclonal antibodies against human. All the data was analyzed by SPSS13.0 software. Results Survivin immunoreactivity was localized in prostatic cell nuclei. Survivin expression in larger enlarged parts (22.08±16. 33)0% was significantly higher than the smaller parts (7. 645±5. 45)%(P<0.01). Positive nuclear or cytoplasm staining was also observed in the Caspase-3 immunoreactivity. Caspase-3 expression was higher in smaller enlarged parts (51. 525±27. 27%) than in larger enlarged parts (33. 125±21.01%) (P< 0.01). Survivin expression in larger part of the enlarged prostates was inversely correlated with caspase-3 expression (r=-0. 474, P<0. 05). However, in smaller part of the enlarged prostates, the expression of the two factors had no relation (r=-0. 313,P>0. 05). Conclusions Survivin and caspase-3 expression patterns are different in the two parts of the dissymmetric enlarged prostates. These different patterns indicate apoptosis playing an important role in BPH development.

AIM To study the role of survivin on the apoptosis of lung cancer cell line induced bycisplatin (DDP) and etoposide (VP16). METHODS The lung adenocarcinoma cell line A549 was chosen in this experiment. The inhibitory effects of chemotherapeutical drugs on A549 cell line were assayed with MTT test. Cultured cells was divided into 3 groups: DDP, VP16 and control. Both DDP and VP16 group were divided into high concentration group and low concentration group, respectively. Expression of survivin gene were detected by reverse transcriptase PCR. Apoptosis was deterinined by flow cytometry. RESULTS Both DDP and VP16 obviously inhibited the lung cancer cell growth with dose and time dependent. Apoptosis and inhibitory rate of survivin gene expression induced by chemotherapeutical drugs was higher than that of control group. The effects also were time dependent. CONCLUSION The inhibition of survivin gene expression may play a critical role on the lung cancer cell apoptosis induced by DDP and VP16.
