1.Enhancing effects of Ginsenosides on cellular Immune function via Hippocampus and its possible mechanism
Chinese Journal of Immunology 1986;0(04):-
The aim of this study was expected to elucidate the possible mechanism of enhancing effects of Ginsenosides (GS) on immune function via hippocampus (HC). Our main results indicate that after the injection of GS into rat bilateral HC directly by condiuts with dose of 50 ?g/day for 4 days, thymocyte proliferative response to Con A and NK activity were increased significantly as compared with those of control groups. Furthemore, it has been found that this elevation coincides with decreased plasma ACTH and corticosterone level in the experimental group. Besides these, GS also can augment the thymocyte proliferating factor in the culture supernatant of HC slices. The data described above suggests that the action of GS induced cellular immunity appears to occur in part of neuroendocrine system by suppression pituitary-adrenal axis or of the promoting factor of HC.

Objective To establish a high quality genomic DNA preparation method from formalin fixed and paraffin embedded tissues (FFPET) by integrating previous DNA extraction methods. Methods We combined classical genomic DNA extraction methods and commercially available DNA affinity column, replaced the de-waxing by dimethylbenzene with water-bath, designed a fast and improved genomic DNA preparation method. We also extracted genomic DNA from paraffin embedded cervical cancer tissues, and checked the quality of DNA by agarose gel electrophoresis and polymerase chain reaction detection. Results The improved genomic DNA extraction method combined the advantages of the water-bath de-waxing and DNA affinity column, making it possible to get high quality genomic DNA from paraffin embedded cervical cancer tissues, and especially efficient to recover genomic DNA fragments larger than 20 kb. Conclusion The improved DNA extraction method is fast and convenient to recover high quality genomic DNA from paraffin embedded tissues.

Objective To assess the immune level of cervical cancer patients and precancerous lesions patients,and investigate the association of Th 1 /Th2 type cytokines expression and clinical pathologic factors in the plasma of Uyghur cervical cancer patients .Methods we collected peripheral blood specimens from cervical cancer patients,precancerous lesion(CINⅢ)patients and controls.The expressions of Th1 type cytokines IL-2, IFN-γand Th2 type cytokines IL-4,IL-10 in plasma were detected by ELISA .Receiver operating characteris-tic curve( ROC curve) was used to analyze the cytokines value of auxiliary diagnosis in cervical cancer .Results The results showed that compared with control group ,the expressions of Th1 type cytokines IL-2,IFN-γin cer-vical cancer and precancerous lesion group were significantly reduced (P<0.05).The expressions of Th2 type cytokines IL -4, IL -10 in cervical cancer and precancerous lesion group were significantly increased ( P <0.05).in cervical cancer group,IL -10 expression gradually increased with tumor pathological staging (P <0.05).IL-2 expression level in Uyghur cervical cancer patients was significantly lower than in Han patients (P<0.05).Compared cervical cancer group with control group ,AUC of IL-2,IFN-γ,IL-4 and IL-10 were 0.979,0.766,0.736 and 0.903.Conclusion Cellular immune level of cervical cancer patients was low and Th1/Th2 shift has occurred , which suggests that it may be one of the mechanisms in immune escape of tumor cells.Th1 /Th2 type cytokines detection has a certain significance for auxiliary diagnosis of cervical cancer .Be-sides,the decrease of IL-2 expression may play an important role in the occurrence and development of Uyghur patients with cervical cancer .

Objective To improve the understanding to transposition of the great arteries with posterior aorta and decrease the clinic misdiagnosis by summarizing their echocardiography features . Methods Echocardiography images were retrospectively reviewed for 7 cases with transposition of the great arteries with posterior aorta who diagnosed in Anzhen Hospital ,and their echocardiography features were summarized .Results In 7 patients ,5 patients had operation ,including 3 for arterial switch operation ,1 for right GLEEN ,1 for right GLEEN and Fortan surgery ,and 2 patients were lost to follow‐up .The echocardiography characters:① Artery short view showed aorta and pulmonary artery existed the half‐surrounding relationship .The aorta was situated posteriorly and the pulmonary artery anteriorly .②Multiple views showed aorta was completely and mostly arised from the right ventricle ,while the pulmonary artery was came off the left ventricle .③ Ventricular septal defects were presented in all cases and aorta could ride the defect of ventricular septal .④ In most cases ,fibrous continuity between the aortic and mitral valve through a ventricular septal defect was found and there was no conus under the aorta .⑤ Some cases could combine the different degree stenosis of the outflow tract of subpulmonary valve and pulmonary valve . Conclusions The connection relationship between two arteries and ventricles can displayed clearly on the long axis view of double outflow tracts of two ventricles under xiphoid process .The acoustic window under the xiphoid process is the key for diagnosis and differential diagnosis of the disease .

Objective To establish differential protein expression profile specific for serum proteome of cervical carcinoma in Uighur women by protein 2-dimensional liquid phase chromatogra-phy. Methods We collected and prepared sera of cervical carcinoma from Uighur women, and sepa-rated and processed data using 2-dimensional liquid phase chromatography system specific for protein (ProteomeLabTM PF-2D ). Results A differential expression profile of serum proteome based on characteristics of protein isoelectrie point and hydrophobic features was successfully established. Fifty-six differentially expressed protein spots were found, among which there was an obvious difference in 12 peaks. Conclusion Two-dimensional liquid phase chromatography is an effective and feasible method to establish differential expression profile of serum proteome and to offer a new way for the screening of serum protein markers of Uighur women with cervical carcinoma.

OBJECTIVETo investigate the relationship between work in shifts and occupational stress.
METHODSA total of 5338 employees from 13 companies were investigated by cluster sampling, and occupational stress measuring tools, job content questionnaire, and effort-reward imbalance questionnaire were used to investigate occupational stress factors, stress reaction, and the condition of work in shifts.
RESULTSThe employees who worked in shifts accounted for 46.6%. The condition of work in shifts varied significantly across different companies, employees with different individual features (including sex, job title, degree of education, age, working years, smoking, and drinking), and employees with different weekly working times(P<0.01 or P<0.05); health status was associated with work in shifts(P<0.01); compared with the employees who did not work in shifts, those who worked in shifts had significantly lower scores of technology utilization, work control level, psychological need, reward, social support, and job satisfaction(P<0.01 or P<0.05), as well as significantly higher scores of physical demands, effort, depressive symptoms, and negative affectivity(P<0.01).
CONCLUSIONWork in shifts can affect health status, and is associated with occupational stress.
