The Book of Changes is known as a famous ancient book in China. In the chapter on Copula of this masterpiece the relations among the changes of heaven and earth, movement and stillness, and Qian and Qun have been revealed through adopting "YiXing" and "LiYi", two varieties of schools of Yi (Change). This paper sets out to compare the depiction of Yin and Yang, movement and stillness recorded in the book of the Yellow Emperor's Classic of Medicine with the notions mentioned above. It is also our attempt to discover the same intrinsic principle existed in both Chinese ancient philosophy and Chinese ancient medicine.

Serum B7-H4 protein levels were measured by enzyme-link immunosorbent assay (ELISA) in 62 patients with epithelial ovarian cancer, 20 patients with benign ovarian diseases, and 30healthy subjects.Serum B7-H4 protein levels in epithelial ovarian cancer, benign ovarian diseases and normal controls were 0.72(0.32,1.88 )μg/L, (0.45±0.21)μg/L,(0.38 ± 0.19 ) μg/L respectively (P＜0.01).The serum level of B7-H4 protein in epithelial ovarian carcinoma was correlated with FIGO stages, lymph node metastasis, histological grade and histological types ( all P ＜ 0.01 ), but not with menopause and ascites (P＞0.05).The receiver operating characteristics curve analysis revealed that B7-H4protein had a sensitivity and specificity of 69% (43/62)and 86%(43/50) for diagnosis of epithelial ovarian cancer.

Objective To investigate the change and clinical significance of the serum level of human epididymis secretory protein 4 (HE4) in elderly patients with epithelial ovarian cancer (EOC).Methods The serum levels of HE4 were determined by ELISA in EOC patients (n= 33), benign ovarian disease patients ( n = 17) and healthy women ( n = 20), all of them aged 60 years or over. And there were other 31 EOC patients and 20 healthy women aged less than 60 years at the same period as controls. Results In healthy people, the serum level of HE4 was higher in the group with age ≥60 years than with age ＜60 years [(32.25± 13. 15) pmol/L vs. (24.59±8.60) pmol/L]. The serum HE4 level had a positive correlation with age (r=0. 525, P＜0.01). The median level of HE4 was significantly higher in elderly EOC patients than in benign ovarian disease patients (81.50 pmol/L vs.45.60 pmol L, U=168.5, P＜0.05) and healthy women (81.50 pmol L vs. 33.30 pmol L, U=76.5, P＜0. 01). The HE4 had a significantly higher area under ROC curve when compared with CA125 (0. 799 vs. 0. 782), while the cut-off value was set 65.43 pmol L with a sensibility and specificity of 66.67% and 86.49% respectively. The diagnostic efficacy of HE4 was higher than CA125. There was no significantly statistical difference between elderly and non-elderly EOC patients in serum HE4 levels (U= 101.2, P＞0. 05). Conclusions Age is an important factor which can affect human serum level of HE4. HE4 determination is helpful in the diagnosis of ovarian epithelial carcinoma in the elderly patients, and the combined detection of HE4 and CA125 is an useful adjuvant diagnostic measure.

Objective To observe the glucose utilization in adipose tissue and skeletal muscle during catch-up growth, and to explore the mechanism of catch-up growth of adipose tissue. Methods Male Wistar rats were randomly divide into normal control group(NC)and catch-up group(RN). Rats in RN group received 50%of food consumed by NC group for 4 weeks, then were re-fed spontaneously as the rats in NC group. In the end of the fifth week(NC1 group and RN1 group)and the sixth week(NC2 group and RN2 group), the experiment was performed. [3]-2-deoxy-glucose was used for detecting the glucose uptake rate. RT-PCR and Western-blot were used for detecting the levels of mRNA and membrane protein of glucose transporter-4(Glut4). Results The glucose uptake rates in adipose tissue and skeletal muscle of RN1 group increased by 189.6%(P<0.01)and reduced by 36.5%(P<0.05)respectively, as compared with NC1 group. After 2 weeks of catch-up growth, the glucose uptake rates in adipose tissue of RN2 group increased by 157.3%(P<0.01)and decreased by 41.5%(P<0.05) in skeletal muscle as compared with NC2 group. However. no significant difference in Glut4 mRNA levels in muscle or in adipose tissue between NC and RN groups were found. The membrane protein of GIut4 after insulin-stimulating in RN1 group and RN2 group reduced by about 46.5%(P<0.01)and 32.1%(P<0.05)in muscle and increased by 116.5%(P<0.01)and 89.9%(P<0.01)in adipose tissue respectively. Conclusion There exists the redistribution of glucose from skeletal muscle to adipose tissue during the early stage of catch-up growth, which results in the catch-up growth of adipose tissue. This change is induced by the tissue-specific alteration of insulin-stimulated Glut4 protein translocation.

Objective To study the regulation of aquaporin-1(AQP-1)changes in the heart of septic rats, compare the correlations of the AQP-1 with myocardial cytokines tumor necrosis factor-α(TNF-α),interleukin-6 (IL-6),and myocardial tissue water content,and to investigate the dexmedetomidine protective effect on myocardia in septic rats and its possible mechanism. Methods According to the random number table methods,90 male Sprague-Dawley(SD)rats were divided into sham operation group,sepsis model group and dexmedetomidine group, 30 rats in each group. The rat sepsis model was established by cecal ligation and puncture(CLP). In the sham operation group,the animal abdomen was only opened and closed without CLP. Half hour before operation in dexmedetomidine group,dexmedetomidine 1μg/kg(2μg/mL)was injected into the vein,while in the model and sham groups,saline 5 mL/kg was subcutaneously injected into the rat after the operation. At 2,12,24,48,72 hours after operation,6 rats were sacrificed and their hearts removed at one time point in a group. Enzyme linked immunosorbent assay(ELISA)was used to detect the content of AQP-1 and the levels of the TNF-α,IL-6 in the myocardial tissue homogenate at all time points,the myocardial tissue water content was detected by dry wet weight,and the correlations between AQP-1 and TNF-α,IL-6 and between AQP-1 and myocardial tissue water content were compared. Results From 2 hours after operation,the levels of the AQP-1,TNF-αand IL-6 in model group were significantly higher than those in the sham operation group;with prolongation of time,the level of AQP-1 and myocardial tissue water content were decreased, but the levels of TNF-α and IL-6 were persistently increased. From 2 hours after operation in dexmedetomidine group,all the above indexes except myocardial tissue water content at 72 hours after operation were significantly lower than those in the model group〔AQP-1(ng/g):9.29±0.15 vs. 9.73±0.26,TNF-α(pg/g):109.47±8.41 vs. 128.13±7.36,IL-6(pg/g):232.95±20.56 vs. 279.71±22.24,myocardial tissue water content:(74.82±6.37)%vs.(75.62±6.39)%,all P<0.05〕,but still higher than those of the sham operation group. The correlation analyses for the septic group showed that the change of AQP-1 was positively correlated to the myocardial water content in early stage(r=0.418,P=0.001)and later stage(r=0.235,P=0.022),and the changes of the AQP-1 in early stage (at post-operative 2 hours)were positively correlated to the concentration changes of the cytokines TNF-α(r=0.235,P=0.021)and IL-6(r=0.345,P=0.003),but in the later stage(at post-operative 72 hours)were negatively correlated with the changes of TNF-α(r=-0.408,P=0.037)and IL-6(r=-0.276,P=0.002). Conclusions In the early stage of septic rats,there is obvious myocardial injury,resulting in the over expression of AQP-1 and the occurrence of myocardial edema,dexmedetomidine can play a role in myocardial protection in such rats and its mechanism is possibly related to the reduction of the expression of AQP-1 and the levels of inflammatory cytokines, and in turn the alleviation of myocardial cell edema.
