Objective To explore the role of CD4+CD25+regulatory T cells(Treg)in the co-culture svstem consisting of T cells and mouse embryo fibroblasts(MEF)infected with murine cytomegalovirus (MCMV)in vitro.Methods A co-culture system of T cells and MCMV infected MEF(MEFMCMV)was established.The viral load in the supernatants was determined by plaque assay.TH1/TH2 differentiation-specific transcription factors T-bet/GATA-3 were assayed by Western blot.The levels of cytokines IL-4,IL-10and IFN-γ in the co-culture supenatants were measured by double-antibody sandwich ELISA.Results After 3 d incubation,the viral load in the supernatants of TdepTreg-MEFMCMC group,in which the T cells depleted Treg(TdepTreg)were co-cultured together with MEFMVMV,was significantly lower than that in MEFMCMV group.And in the co-cultivation of MEFMCMV and T cells without Treg the expressions of T-bet/GATA-3,IL-4,IL-10 and IFN-γ incteased significantly.Compared with the virus content in the TdepTreg-MEFMCMV group,the MCMV load in the"add-on Treg group"increased and the levels of T-bet/GATA-3 and IFN-γ were lower,and the expression of IL-4 didn't show any significant difference. Compared with the level of IL-10 in the TdepTreg-MEFMCMV group,the IL-10 level in the"add-on TREG group"didn't show any significant differece when the Treg ratio among total T cells was 1%～2%,and increased significantly when the Treg ratio was more than 5%.These eflfects were all correlated with Treg ratios in a dose-dependent manner.Conclusion MCMV infected MEF can induce the proliferation and activation of effector T cells,but Treg can inhibit the T cell-mediated protective effect on MCMV infection.

Objective To evaluate the value of ultrasound elastography score and strain ratio index in the differential diagnosis of thyroid solid nodules. Methods Eighty-six thyroid solid nodules of 69 patients were divided into 2 groups based on their pathologic results: benign nodules group and malignant nodules group.Compared with pathological results, each thyroid solid nodules' elastographic scores and strain ratio index were respectively analyzed. The sensitivity, specificity and accuracy of elasticity score and strain ratio index were calctlated.The receiver operator characteristic (ROC) curves were drawn according to the results, to choose the best cut-off value.Results There were 67 nodules in benign nodules group and 19 nodules in malignant nodules group. The diameter of benign nodules was (2.05 ± 0.21)cm, malignant nodules was (1.62 ± 0.12)cm. There were no significant differences in the elasticity score and strain ratio index between benign and malignant nodules(t= - 1.736, P ＞ 0.05). Malignant lesions had a higher score and strain ratio index(median 3, 3.97, respectively) than benign ones(median 2, 1.66,respectively, Z = - 5.290, - 5.450, all P ＜ 0.05). If the cut-off value of the elastographic scores was equal or more than 3, the sensitivity, specificity and accuracy were 84.2%(16/19) ,86.6%(58/67) and 86.0%(74/86), respectively,with an area under ROC curve of 0.854. If the cut-off value of the strain ratio index was equal or more than 2.50,the sensitivity, specificity and accuracy were 89.4%(17/19),86.6%(58/67) and 87.2%(75/86), respectively, with an area under ROC curve of 0.911. Conclusion Elasticity score and strain ratio index are helpful in differentiating benign and malignant lesions of thyroid with high clinical value.

In view of the effective traditional Chinese medicine (TCM) in the treatment of clinical depression, the mechanism is not clear, this study attempts to research the cause of depression in a complex situation to lay the foundation for the next step of TCM curative effect evaluation. Based on the brain wave of 120 depression patients and 40 ordinary person, the change regulation of acetylcholine, dopamine, norepinephrine, depression neurotransmitters and excited neurotransmitters in the whole and various encephalic regions' multi-neurotransmitters of depression patients-serotonin are analysed by search of encephalo-telex (SET) system, which lays the foundation for the diagnosis of depression. The result showed that: contrased with the normal person group, the mean value of the six neurotransmitters in depression patients group are: (1) in the whole encephalic region of depression patients group the dopamine fall (P < 0.05), and in the double centralregions, right temporal region and right parietal region distinct fall (P < 0.01); (2) in the right temporal region of depression patients group the serotonin rise (P < 0.05); (3) in the right central region, left parietal region of depression patients group the acetylcholine fall (P < 0.05), left rear temporal region fall obviously (P < 0.01). The correlation research between antagonizing pairs of neurotransmitters and neurotransmitters: (1) the three antagonizing pairs of neurotransmitters-serotonin and dopamine, acetylcholine and norepinephrine, depression neurotransmitters and excited neurotransmitters, in ordinary person group and depression patients group are characterizeed by middle or strong negative correlation. Serotonin and dopamine, which are characterized by weak negative correlation in the right rear temporal region of ordinary person group, are characterized by strong negative correlation in the other encephalic regions and the whole encephalic (ordinary person group except the right rear temporal region: the range of [r] is [0.82, 0.92], P < 0.01)/(depression patients group:the range of [r] is [0.88, 0.94], P < 0.01); acetylcholine and norepinephrine, in the whole and various encephalic region are characterized by middle negative correlation(ordinary person group:the range of [r] is [0.39, 0.76], P < 0.01 or P < 0.05)/(depression patients group: the range of [Ir] is [0.56, 0.64], P < 0.01); depression neurotransmitters and excited neurotransmitters are characterized by middle strong negative correlation (ordinary person group: the range of [r] is [0.57, 0.80], P < 0.01)/(depression patients group: the range of [r] is [0.68, 0.78], P < 0.01). (2) The two neurotransmitters which are not antagonizing pairs of neurotransmitters, serotonin and excited neurotransmitters, or acetylcholine and depression neurotra-nsmitters, or dopamine and depression neurotransmitters in the various encephalic regions are characterized by weak negative correlation. Serotonin and excited neurotransmitters are characterizeed by weak negative correlation (ordinary person group: in the right central region, left parietal region, double front temporal regions, right rear temporal region, the range of [r] is [0.25, 0.50], P < 0.01 or P < 0.05)/(depression patients group: in the whole encephalic regions, double parietal regions, double occipital regions, right front temporal region, left central region, left frontal region, the range of [r] is [0.18, 0.37], P < 0.01 or P < 0.05); acetylcholine and depression, neurotransmitters are characterized by weak negative correlation (ordinary person group: in the double frontal regions, left parietal region, left front temporal region, right rear temporal region, the range of [r] is [0.31, 0.46], P < 0.01 or P < 0.05)/(depression patients group: in double rear temporal regions, right front temporal region, double occipital regions, left central region, the range of [r] is [0.20, 0.32] , P < 0.01 or P < 0.05); do-pamine and depression neurotransmitters are characterized by weak middle negative correlation (ordinary person group: in left parietal region, right central region, left frontal region, left occipital region, double front temporal regions, the range of [r] is [0.33, 0.68], P < 0.01 or P < 0.05)/(depression patients group: in the whole region and other various regions except the left frontal region, right central region, the range of Irl is [0.21, 0.34], P < 0.01 or P < 0.05). Dopamine and acetylcholine or norepinephrine and serotonin are characterized by weak positive correlation in all encephalic regions. Dopamine and acetylcholine are characterized by weak positive correlation (ordinary person group: in left frontal region, right parietal region, left front temporal region and left rear temporal region, the range of [r] is [0.37, 0.46], P < 0.01)/(depression patients group: in the whole region and the orther various regions except the double central regions, the range of [r] is [0.23, 0.5], P < 0.01 or P < 0.05); norepinephrine and serotonin are characterized by weak positive correlation (ordinary person group: in double front temporal regions, double rear temporal regions, right frontal region and left parietal region, the range of [r] is [0.34, 0.48], P < 0.01 or P < 0.05)/(depression patients group: in the whole and various regions, the range of [r] is [0.18, 0.42], P < 0.01). The main differences between the depression patients group and ordinary person group are: (1) In the whole regin, left frontal region and right central region of depression patients group, the six neurotransmitters all fall normally (P < 0.05). (2) The percent of dopamine falling or including dopamine falling, or including dopamine falling and serotonin rising in depression patients group increases. The percent of dopamine falling or including dopamine falling in the whole region, right frontal region, right central region increases (P < 0.01), such as dopamine decreasing, serotonin increasing dopamine decreasing, serotonin increasing acetylcholine decreasing dopamine decreasing, dopamine decreasing norepinephrine increasing depression neurotransmitters decreasing, serotonin increasing acetylcholine decreasing dopamine decreasing neurotransmitters increasing and so on. (3) The percent of acetylcholine falling, or including acetylcholine falling, or including acetylcholine falling and neurotransmitters (beta)-receptor)rising in depression patients group increases. The percent of acetylcholine falling, or including acetylcholine falling in the right temporal region, double central regions increases (P < 0.05 or P < 0.01), such as acetylcholine decreasing, acetylcholine decreasing neurotransmitters increaseng, acetylcholine decreasing neurotransmitters increasing depression neurotransmitters decreasing, serotonin increasing acetylcholine decreasing dopamine decreasing neurotransmitters increasing and so on. It's showed in research that depression patients' brain are characterized by multi-neurotransmitters abnormal, the synchronous change of multi-neurotransmitters has some certain regularities, which are not the simple linear relation. It's conformed that the three antagonizing pairs, neurotransmitters-serotonin and dopamine, acetylcholine and norepinephrine, depression eurotransmitters and excited neurotransmitters of ordinary person group and depression patients group, are both characterized by strong antagonizing relation, that the two neurotransmitters which are not antagonizing pairs of neurotransmitters are characterized by weak positive correlation or negative correlation, prompt maybe has the indirect causal relationship. And the change of six neurotransmitters in depression patients' various encephalic regions is rather complex. It's conformed preliminarily that the right frontal region and right central region are characterized by dopamine decreasing, acetylcholine decreasing, serotonin increasing dopamine decreasing, serotonin increasing acetylcholine decreasing dopamine decreasing, dopamine decreasing norepinephrine increasing excited neurotransmitters decreasing, serotonin increasing acetylcholine decreasing dopamine decreasing neurotransmitters increasing, acetylchoine decreasing neurotransmitters increasing, acetylcholine decreasing neurotransmitters increasing excited neurotransmitters decreasing and so on. Contrasted with the ordinary person group, the depression patients group have the notable difference.
