Objective To explore the significance of signal and volume change from magnetic resonance imaging (MRI) of hysteromyoma before and after uterine artery embolization (UAE) in the therapy evaluation. Methods MRI was performed in 30 patients (50 hysteromyoma) before and 3,6 and 12 months after UAE. They were grouped by location, signal and size. The MRI signal changes and the hysteromyoma's volume reduction ratio were measured. Results After 3,6,12 months, MRI of hysteromyoma was changed significantly, and all hysteromyomas had lower T2WI signals than before, some of which had higher T1WI signals. Hysteromyoma's volumes were progressively reduced, the majority of which shrinked significantly within 3 months. Evaluated by 12 month's volume changes, significant volume reduction was found in submucous fibroids, and significant difference was showed compared with intramural fibroids and subserosal fibroids (88.9 % vs. 73.7 % and 68.3 %, P=0.036, P=0.019), meanwhile,the latter two had no significant difference (P=0.384). The volume reduction rate in rich cell fibroids was higher than those in ordinary no degeneration fibroids and degeneration type, and there were significant differences (85.7 % vs. 72.1 % and 63.4%, P=0.038, P=0.014). Besides, the latter two had no significant difference (P=0.364). Large fibroids shrinked more obviously than small ones with significant difference (75.2 % vs. 59.6 %, χ2=4.563, P=0.044). Conclusion MRI is useful for the evaluation of efficacy in hysteromyoma before and after UAE, which can provide the better interventional treatment for the patients in regard to different sensitivity of hysteromyoma to UAE.

Objective To evaluate the relationship between the levels of microRNA-125b (miR-125b) and miR-181c in cerebrospinal flnid (CSF) before joint replacement and postoperative delirium (POD) in elderly patients.Methods Fifty-two patients of hoth sexes,aged ≥ 65 yr,weighing 45-70 kg,of American Society of Anesthesiologists physical status Ⅰ-Ⅲ,scheduled for elcctive hip or knee replacement under spinal anesthesia,were included in the study.CSF was collected after successful puncture to measure the levels of miR-181c and miR-125b by fluorescent quantitative real-time polymerase chain reaction.The patients were divided into POD group and non-POD group using the Chinese reversion of Confusion Assessment Method on postoperative days 1 and 2.Results The incidence of POD was about 28％ in the patients underwent hip or knee replacement.Compared with non-POD group,the preoperative level of miR-181c in CSF was significantly increased (P＜0.05),and no significant change was found in the preoperative level of miR-125b in CSF in POD group (P＞0.05).Conclusion The level of miR-181c in CSF before joint replacement is related to POD in elderly patients,and the preoperative level of miR-181c in CSF is a risk factor for POD.

OBJECTIVETo examine the expression of matrix metalloproteinases (MMP)-2, -9, tissue inhibitor of matrix metalloproteinase (TIMP)-1 and hs-CRP, and their relationship with coronary artery in children with Kawasaki disease.

METHODSOne hundred and fifty-one children with Kawasaki disease (111 cases with coronary artery damage and 40 cases without) and 60 healthy children were enrolled. The expression of MMP-2, MMP-9 and TIMP-1 was detected using ELISA, and the hs-CRP concentration was measured using the endpoint nephelometry.

RESULTSThere were significant differences in the level of MMP-2, MMP-9 and hs-CRP between the patients with or without coronary artery damage and the healthy children (p<0.05). The levels of MMP-2, MMP-9 and hs-CRP were the highest in the cardiovascular damage group (p<0.05). There were positive correlations between MMP-2, MMP-9 and TIMP-1 in children with Kawasaki disease.

CONCLUSIONSMMP-2, MMP-9, TIMP-1 and hs-CRP may play important roles in the development of Kawasaki disease. The combined measurement of MMP-2, MMP-9 and hs-CRP may be useful in the evaluation of the severity in children with Kawasaki disease.

Objective: To investigate the effect of perioperative fluid therapy on early postoperative pulmonary complication (PPC) after orthotopic liver transplantation (OLT). Methods: The clinical data of 132 patients who underwent OLT in the First Affiliated Hospital of Xi′an Jiaotong University from April 2016 to December 2017 were analyzed retrospectively. These patients included 96 males and 36 females, aged (47.3±9.6) years (range: 24-69 years). Based on the clinical manifestations, laboratory and imaging findings of patients in ICU and PPC occurrence within 7 days after OLT surgery, the patients were divided into 2 groups: non-PPC group and PPC group. Univariate and multivariate logistic regression analyses were used to evaluate the association between perioperative variables and PPC. The Kaplan-Meier method was used to estimate cumulative survival of recipients with or without PPC within 2-years. Results: During the follow-up, 11 patients (8.3%) died and 72 patients (54.5%) developed PPC after operation. There were 34 cases, 6 cases, 3 cases, 4 cases, 15 cases, 6 cases and 4 cases of only pleural effusion, only pulmonary edema, only pneumonia, pleural effusion with pneumonia, pleural effusion with pulmonary edema, pleural effusion with atelectasis, and pleural effusion with pneumonia and pneumonia in PPC, respectively. Univariate analysis showed that the preoperative factors (model for end-stage liver disease score), the intra-operative factors (duration of surgery, total infusion volume, total blood products) and the postoperative cumulative fluid balance within the first 24 h, 48 h, and 72 h were the prognosis factors of PPC (P<0.05). At least two out of the first three postoperative days with a fluid balance of ≤-500 ml was a protective factor. Using multivariate analysis by Logistic regression, only the red blood units >10 U (OR=3.55, 95% CI: 1.35-9.26, P=0.010) and the cumulative fluid intake >12 L (OR=2.98, 95% CI: 1.14-7.80, P=0.026) within the first 72 h after operation were independent prognosis factors of PPC after OLT. Kaplan-Meier analysis showed that the cumulative survival rate was lower in PPC group than that in non-PPC group (χ²=6.590, P=0.01). Conclusion Massive red blood cell transfusion and the cumulative fluid volume >12 L during perioperative 72 hours are independent prognosis factors of PPC after OLT.

Based on leads provided by Neijing and other literature, analyze origins of the three-yin and the three-yang and the their respective contents of yin and yang, indicating the principle that the order of yang-qi from more to less is Yang ming, Tai yang, Shao yang, and the order of yin-qi is Tai yin, Shao yin, Jue yin. According to the location of five (six) zang-organs, respective yin-qi content is defined, and according to the principle of more yin-qi matches more, and less yin-qi matches less, five (six) zang-organs match each other. The zang-organs above the diaphragm joints with The Hand-Channels and the zang-organs below the diaphragm with The Foot-Channels, completing the nomenclature of twelve meridians. The names of the six yang-channels correspond to the yin-channels of the exterior-interior relationship, the yin-channels link with hands (feet), and the yang-channels also link with hands (feet), and the amount of yin-qi of the zang-organs corresponding to the yin-channels and the amount of yang-qi of the fu-organs corresponding to yang-channels are in a state of balance. Based on this principle, nomenclature of six channels are completed. Emphasize that the nomenclature of twelve meridians contains profound TCM theories, especially, TCM, by yin-yang, three-yin and three- yang, illustrates living phenomena from the whole to the system and organ level in human body, and the scientific principle "yin-yang can be unlimitedly divided" and its significance, which must guide the studies on living phenomena with modern life sciences from the whole to the molecular level.

OBJECTIVEAlmost every neonate receives Bacillus Calmette-Guerin (BCG) vaccination in China. The authors' previous study showed that BCG promoted cord blood monocyte-derived dendritic cells maturation and induced high level of interleukin (IL)-10, medium level of interferon (IFN)-gamma, but low level of IL-4 production by cord naive T cells. The experiments in the present study were designed to explore the effects of neonatal BCG vaccination on immune functional development of splenic T cells in mice in vivo.

METHODSNeonatal BALB/c mice were inoculated with BCG intraperiotoneally. Four weeks later, spleen cells of mice were isolated and surface molecular markers of CD4, CD25 and CD44 and intracellular IFN-gamma, IL-10, and IL-4 in CD3(+) T cells were detected by flow cytometry. Furthermore, mRNA expression of transcription factor T-bet, Foxp3 and GATA-3 were analyzed by RT-PCR.

RESULTSThe percentage of total CD4(+) T cells decreased [(23.50 +/- 2.59)% vs. (47.38 +/- 10.41)%, P < 0.01] but the percentage of CD25(+) [(24.92 +/- 2.74)% vs. (20.27 +/- 2.85)%, P < 0.05] and CD44(+) [(89.29 +/- 2.56)% vs. (82.98 +/- 5.51)%, P < 0.05] T cells in CD4(+) T cells was higher in BCG-vaccinated mice than that in controls. Meanwhile, the percentage of IFN-gamma positive [(6.52 +/- 2.40)% vs. (3.13 +/- 2.03)%, P < 0.05] and IL-10 positive [(14.81 +/- 3.65)% vs. (10.90 +/- 1.61)%, P < 0.05] but not IL-4 positive [(1.17 +/- 0.46)% vs (1.51 +/- 0.75)%, P > 0.05] cells in CD3(+) T cells of BCG-vaccinated mice was significantly higher than that of non-BCG-vaccinated mice. In comparison with BCG-naive mice, T-bet was significantly high in BCG-vaccinated mice [T-bet/beta-actin 0.44 +/- 0.11 vs. 0.28 +/- 0.06, P < 0.05], but there was no significant difference in GATA-3 [GATA-3/beta-actin 0.46 +/- 0.08 vs. 0.50 +/- 0.10,P > 0.05] and Foxp3 [Foxp3/beta-actin vs. 0.27 +/- 0.11 and 0.30 +/- 0.16, P > 0.05] mRNA expression between the two groups.

CONCLUSIONNeonatal BCG vaccination could induce strong Th1 but weak Th2 response as reported previously. Though neonatal BCG vaccination was not capable of inducing CD4(+)CD25(+) regulatory T cell response with Foxp3 expression, it caused increase of IL-10(+) CD3(+) cells which might represent some regulatory T cells producing IL-10.

To explore the possible linkage between telomerase and acute leukemia, we detected telomerase activity expressed in 3 leukemia cell lines, 22 acute leukemia bone marrow and 6 normal bone marrow with PCR ELISA assay. Results showed that telomerase activities of three leukemia cell lines were positive with the average (1.57 +/- 0.056) U, normal bone marrow samples average was (0.085 +/- 0.081) U, telomerase value from 22 acute leukemia patients was (0.512 +/- 0.294) U. Telomerase activity is higher expressed in acute leukemia than normal samples and decreased significantly after chemotherapy (P < 0.01). The results suggested that telomerase activity was related to some malignant diseases and might be used as a marker for tumor diagnosis and therapy.

After consulting literature, following the original meaning of the paper about slow-rapid reinforcing-reducing method in Huangdi's Internal Classic, in combination with explanation of later ages, and comprehension and clinical experience of the authors, it is put forward that the slow-rapid reinforcing-reducing method in Huangdi's Internal Classic is not single manipulation method, but it is a guiding principle for reinforcing-reducing manipulation, it includes many manipulation methods and they were listed, and all of the reinforcing-reducing methods of later ages are developed from these. In the teaching material Acupuncture and Moxibustion Sciences they are included in single reinforcing-reducing method, reducing extension and intension of this definition. The relative description in the teaching material only is slow-rapid reinforcing-reducing method of narrow sense, but the manipulations can be divided into qi-carrying manipulating needle type and three-one pushing-pulling type.
