BACKGROUND:Airway epithelial regeneration can effectively inhibit submucosal hyperblastosis and the occurrence of obliteration. Studies demonstrated that ventilation could accelerate the regeneration of airway epithelium. OBJECTIVE:To establish and improve an orthotopic tracheal transplantation model and to further observe the effects of ventilation on trachea in alogeneic mice. METHODS:C57BL/6 mouse's tracheal served as donor, and BALB/c mouse's tracheal as recipient. This experiment contained two groups. In the experimental group, the membranous part of trachea was longitudinaly dissected in two donors and sutured into an enlarged trachea, which was implanted in the recipient. In the control group, donor's trachea was implanted into the recipient in situ. Samples were obtained and detected at 28 days after surgery. RESULTS AND CONCLUSION: Hematoxylin-eosin staining results demonstrated that compared with the control group, wel-differentiated ciliated epithelium was visible in the epithelial lamina of tracheal lumen, accompanying a few non-ciliated single or stratified squamous epithelium, mild submucosal fibrosis and inflammatory cel infiltration. Morphological analysis revealed that ciliated epithelial proportion in the experimental group was higher than in the control group (P < 0.05). The ratio of lamina propria to the tracheal cartilage, submucous fibrous tissuearea and the degree of lymphocyte infiltration were lower in the experimental group than in the control group (P < 0.05). Immunohistochemical staining demonstrated that the transplanted tracheal epithelium in both groups was recipient epithelial phenotype. Results verified that a modified orthotopic tracheal transplantation model was successfuly established. The increased ventilation of the tracheal alografts can accelerate the differentiation of tracheal epithelium. The wel-differentiated airway epithelium inhibited the proliferation of fibroblast.

OBJECTIVETo discuss the anti-tumor effect of Xihuang pill on tumor-bearing rats and its effect on the immune clearance function of tumor-bearing organisms.
METHODWalker256 tumor cells were adopted to establish the tumor-bearing rat model. The rats were randomly divided into five groups: the normal control group, the model control group, the lentinan group and Xihuang pill low dose, middle dose and high dose groups, with 10 rats in each group, and continuously treated and given drugs for 14 d after modeling. Blood and tumors were collected from abdominal aorta to calculate the tumor inhibition rate. The content of CD3+, CD4+, CD8+ T cells and adhesion molecule B7-1 (CD80) in peripheral blood were detected by flow cytometry (FCM). The expressions of IL-2 and IFN-gamma in were determined by ELISA.
RESULTThe tumor inhibition rate of the Xihuang pill high dose group was 33. 1 percent. Compared with the model group, the Xihuang pill large dose group showed significantly low IL-2, IFN-gamma, CD3+, CD4+, B7-1 in peripheral blood, with statistical significance in their differences (P < 0.05).
CONCLUSIONXihuang pill could show its anti-tumor effect by enhancing the immune clearance function and increasing IL-2, IFN-gamma, CD3+ T, CD4+ T, B7-1 in peripheral blood.

Objective To explore the expressions and significance of miRNA - 101,enhancer of ZESTE homo-log 2(EZH2)and transforming growth factor(TGF)- β1 in the kidneys with complete uniateral ureteral obstruction (CUUO). Methods Thirty male SD rats,(6 ± 1)weeks old,weighted(150 ± 10)g,were divided into sham group, 7 - day group with CUUO and 14 - day group with CUUO by using random number table method,10 rats in each group. The obstructed kidney samples were collected in 7 and 14 days,respectively,for detecting the expression of miRNA -101 by real time - polymerase chain reaction(RT - PCR)and TGF - β1 and EZH2 protein by Western blot,immuno-histochemistry and hematoxylin - eosin staining. Their correlated expressions were analyzed. Results RT - PCR results showed that the expressions of miRNA - 101 in sham group and 7 - day group with CUUO were(12. 69 ± 1. 60)times and(3. 74 ± 1. 24)times which were higher than those of 14 - day group with CUUO,respectively,there was a signifi-cant difference among these 3 groups(P ﹤ 0. 05). The expressions of TGF - β1 and EZH2 proteins were 1. 14 ± 0. 12, 1. 04 ± 0. 14,0. 76 ± 0. 18 and 1. 04 ± 0. 04,0. 89 ± 0. 03,0. 73 ± 0. 02 in 14 - day group with CUUO,7 - day group with CUUO and sham group,respectively. There was a negative correlation between miRNA - 101 with EZH2( r =- 0. 92,P ﹤ 0. 05),and negative correlation with TGF - β1(r = - 0. 63,P ﹤ 0. 05),and positive correlation between EZH2 and TGF - β1(r = 0. 67,P ﹤ 0. 05);the expressions of miRNA - 101,EZH2 and TGF - β1 were associated with each other in obstruction renal in different time periods. Conclusions With the extension of obstruction time, miRNA - 101 expression decreased,EZH2 and TGF - β1 expression increased,evidently,which indicates that the de-velopment of renal interstitial fibrosis may be affected through regulating EZH2 expression of renal obstruction through miRNA - 101 in the young rats.

BACKGROUND:The bispectral (BIS) index is a processed electroencephalogram (EEG) parameter with extensive validation and demonstrated clinical utility. The study aimed to investigate the correlation between the BIS index and the prognosis of patients with coma in the ICU. METHODS:A total of 208 patients with coma in the ICU were enrolled in this study. According to the BIS value, the patients were divided into four groups:group I, BIS value 0 to 20; group Ⅱ, BIS value 21 to 40; group Ⅲ, BIS value 41 to 60; and group IV, BIS value greater than 60. The difference in BIS values with the differences in prognosis of patients with coma was compared between the four groups, and the prognosis of patients with coma was stratified into consciousness, coma, vegetative state, and brain death. Subsequently, the best cut-off score of BIS values calculated for determining the correlation between BIS value and mental state was proposed. RESULTS:There are no significant differences in the age and APACHE Ⅱ scores between the four groups (P>0.05). An inverse correlation was observed between BIS value and mental state (r=–0.749, P=0.00). According to the ROC curve, as BIS value was greater than 42.5, there were higher sensitivity and specificity in conscious-coma patients. CONCLUSION:BIS value is correlated with the prognosis of patients with coma in ICU, and BIS value can be a useful marker for estimating the prognosis of comatose patients.
