ABSTRACT
Objective:Based on the method of metabonomics, the intervention effect of Dingchuan decoction on neutrophilic asthma and its possible mechanism were analyzed from the changes of endogenous metabolites.Methods:Forty C57BL/6 mice were randomly divided into five groups: normal group (group A), neutrophilic asthma model group (group B), Dingchuan decoction low dose treatment group (group C), Dingchuan decoction medium dose treatment group (group D), and Dingchuan decoction high dose treatment group (group E), with 8 mice in each group.B/C/D/E group used ovalbumin (OVA) and complete Freund′s adjuvant (CFA) to induce sensitized mice to establish neutrophilic asthma model, and C/D/E group used Dingchuan decoction with different concentrations of crude drugs for intervention treatment.Buxco small animal lung function tester was used to evaluate the airway reactivity of mice; The total number of white blood cells in bronchoalveolar lavage fluid (BALF) was counted by counting plate, and the number was classified by cell smear staining; The pathological changes of lung tissue were observed by hematoxylin and eosin (HE) staining.The serum metabolites of mice in each group were detected by high performance liquid chromatography coupled with four pole time of flight mass spectrometry (UPLC-Q-TOF-MS/MS). The commonly used principal component analysis (PCA), partial least squares discriminant analysis (PLS-DA), orthogonal partial least squares discriminant analysis (OPLS-DA) models were used for statistical analysis of the metabolite profiles in serum. The intervention effect of Dingchuan decoction and its possible mechanism were reflected from the changes of endogenous metabolites.Results:(1) General behavior observation: except mice in group A, mice in other groups showed asthma symptoms of different degrees during the challenge period. The symptoms of mice in each treatment group (group C, D, E) of Dingchuan decoction were less than those in group B. (2) Airway reactivity: the airway reactivity of mice in group B to methacholine (MCh) increased with the inhalation concentration, and the airway resistance at each concentration of MCh was significantly higher than that in group A (all P<0.01); the airway reactivity in group C, D and E was lower than that in group B (all P<0.01); the airway reactivity in group D and E was lower than that in group C (all P<0.05). There was no significant difference in airway reactivity between group D and E ( P>0.05). (3) Airway inflammatory cell infiltration: the total number of white blood cells (WBC) and percentage of neutrophil in BALF of group B were significantly higher than those of group A (all P<0.01). The total WBC and percentage of neutrophil in group C, D and E were lower than those in group B (all P<0.01). The total number of WBC and percentage of neutrophil in group D and E were lower than those in group C (all P<0.01). There was no significant difference between group D and group E (all P>0.05). (4) Pathological changes of lung tissues: no pathological changes were observed in the lung tissues of group A mice. In group B, typical pathological changes such as bronchial lumen stenosis, intraluminal mucosal folds hyperplasia, epithelial cell exfoliation, swelling, mucous embolus, alveolar and lung tissue structure destruction, massive inflammatory cell infiltration around bronchus and blood vessels were observed, among which neutrophil and lymphocyte infiltration were the most obvious. The damage of lung tissue structure, bronchial mucosa edema and inflammatory cell infiltration in Dingchuan decoction treatment groups were significantly improved compared with group B, and the pathological changes of lung tissue in group D were relatively light. (5) Metabolomics analysis: PCA, PLS-DA and OPLS-DA analysis of serum metabolites in each group showed that serum metabolites in group A and group B were significantly different. The metabolic pathway analysis showed that Dingchuan decoction with different crude drug concentrations could improve the metabolic disorders caused by asthma in different degrees. Conclusions:Dingchuan decoction can effectively reduce airway inflammation and airway hyperresponsiveness in mice with neutrophil asthma, and effectively regulate metabolic abnormalities caused by neutrophil asthma.

Objective To investigate the effect ofYupingfeng granule combined with Desloratadine Citrate Disodium tablets on the clinical efficacy and immune function in patients with allergic rhinitis.Methods A total of 112 patients with allergic rhinitis were randomly divided into two groups according to their order of treatment. The patients in the control group (n=56) were treated with Desloratadine Citrate Disodium tablets, and the patients in the experimental group (n=56) were treated withYupingfeng granule and Desloratadine Citrate Disodium tablets. The efficacy of clinical, the rate of adverse reaction, the improvement of immune and the rate of recurrence were compared between the two groups. Results The total effective rate of the experimental group was 94.64%, it is higher than the control group 85.71%, and the difference was statistically significant (Z=-3.254,P<0.01). After the treatment, runny nose (1.2 ± 0.1vs. 2.0 ± 0.2,t=6.420), nasal itching (1.2 ± 0.3vs. 1.7 ± 0.3,t=7.003), sneezing (0.8 ± 0.1vs. 1.3 ± 0.1,t=6.716), stuffy nose (1.1 ± 0.1vs. 1.6 ± 0.3,t=7.256)scores in the experimental group were significantly lower than those in the control group (P<0.05). There was no significant difference in the total IgE (114.48 ± 9.85 IU/mlvs. 130.64 ± 10.51 IU/ml,t=6.994) and VCAM-1(512.56 ± 13.84 μg/Lvs. 624.98 ± 7.06 μg/L,t=7.803) between the two groups (P<0.05). The levels of IL-4(16.25 ± 1.53 ng/Lvs. 22.38 ± 3.16 ng/L,t=5.458), IL-10 (15.98 ± 2.43 ng/Lvs. 21.82 ± 1.75 ng/L, t=6.149), LTB4 (59.14 ± 0.96 ng/Lvs. 67.46 ± 3.04 ng/L,t=5.342) in the experimental group were significantly lower than those in the control group (P<0.05). Six-month after the treatment, the relapse rate of the experimental group was 5.36%, while the control group was 16.07%, and the difference between two groups were significant (P<0.05).Conclusions The combination ofYupingfeng granule and Desloratadine Citrate Disodium tablets in the treatment of allergic rhinitis can significantly improve the clinical symptoms, adjust the immune function and reduce the recurrence of the disease.

ABSTRACT
Objective To investigate the Influence of FOXC1 downregulating on biological behavior of nasopharyngeal carcinoma (NPC) 5-8F cell lines. Methods Western blotting was used to detect the protein levels of FOXC1 in human immortalized nasopharyngeal cell lines NP69, nasopharyngeal carcinoma cell lines 6-10B with lower metastasis potential and nasopharyngeal carcinoma cell lines 5-8F with higher metastasis potential. siRNA was used to downregulate the expression of FOXC1 in 5-8F cell lines, and then ability of migration and invasion were observed. Results FOXC1 protein expression level in NP69 cell lines, 6-10B cell lines and 5-8F cell lines were (0.27 ± 0.04), (0.7 ± 20.06), (1.08 ± 0.05) respectively, and the difference was statistically significant (P < 0.05). Also ability of cell migration and invasion significantly weakened after FOXC1 depletion in 5-8F cell lines (P < 0.05). Conclusion FOXC1 might regulate invasion and metastasis of nasopharyngeal carcinoma through changing expression of Fibronectin and Vimentin, and FOXC1 may be an available target for molecular target therapy of nasopharyngeal carcinoma.
ABSTRACT
Objective To explore the dynamic changes of endothelial barrier antigen (EBA) and vascular endothelial growth factor (VEGF) expressions in cerebral cortex under the condition of blood-brain barrier damage in rats following radi?ation-induced brain injury, which provided clinical references. Methods Forty-eight clean grade male SD rats were divid?ed into the control group and 7 d, 14 d, 28 d after brain irradiation group (n=12 for each group) by using stochastic indicator method. The radiation-induced brain injury model was established by using electronic computer X-ray tomography tech?nique. The 3%Evans blue (EB) was injected into rats according to the dose of 3 mL/kg via the tail vein, then the blood ves?sels of cerebral cortex were exposed after having a craniotomy. EB extravasation was detected by microcirculation micro?scope. The permeability of blood-brain barrier was evaluated by using microscope vascular camera device. The expressions of EBA and VEGF in the cerebral cortex were measured by immunohistochemistry staining in each group. Results Both of EB extravasation and VEGF expression in rat cerebral cortex were significantly increased in injury group at day 7, 14 and 28 after brain irradiation compared with those of control group (P<0.05), and which were gradually decreased from day 7 to day 28 after brain irradiation. There were significant differences in EB extravasation and VEGF expression between the injury subgroups (P<0.05). There was a positive correlation between EB extravasation and VEGF expression (r=0.898, P<0.001). The expression levels of EBA were decreased at different time points in injury groups compared with those of control group (P<0.05), and gradually increased from day 7 to 28 after injury. There were significant differences in expression levels of EBA between injury subgroups (P<0.05). The expression of EBA was negatively correlated with EB extravasation (r=-0.866, P<0.001). Conclusion The increases of blood-brain barrier permeability have important relation to the decreases of EBA expression and the increases of VEGF expression after radiation-induced brain injury.
ABSTRACT
Objective To summarize the clinical experience of successful liver transplantation from infant donation after cardiac death (DCD) for infant with biliary astresia (BA).Methods The donor was a 16-months-old girl with a body weight of 10 kg,who died of irreversible anoxic cerebral damage after sudden asphyxiation.The recipient was a 24-months-old girl with a body weight of 12 kg,who suffered from icteric concurrent late biliary cirrhosis after the Porta-jejunum anastomosis because of congenital BA.The DCD liver was classically orthotopically transplanted into the infants recipient.The warm ischemia time was 7 min,the cold ischemia time was 360 min,and the graft volume to the standard liver volume (GV/SLV) was 1.02.After operation,the vital signs and transplanted liver function of the recipient were monitored,and the recipient was given treatments of anti-infection,anticoagulation,and improving the microcirculation.The recipient was treated with the triple immunosuppression protocol of tacrolimus,mycophenolate and prednisone to prevent rejection.Results The operating time of the recipient was 480 min,the non-liver stage was 65 min,and the blood loss was 230 mL.The endotracheal intubation was removed from the recipient at 12 h,and the recipient started to eat at 48 h aftcr operation.The recipient had a hepatic artery thrombus on the 3rd and 15th day after operation,and the hepatic artery had re-blood-supply after the hepatic artery catheterization and continuous perfusion with urokinase.The recipient was discharged on the 42nd day,and the recipient was in satisfactory condition to present.Conclusion The infant DCD liver is a better graft for infant liver transplantation for BA.The surgical complications can be reduced with matched volume of donor-recipient liver; and it can guarantee a successful operation with perfect operative technique and careful perioperative management.

ABSTRACT
A series of 12 cases of tumors located in the vicinity of foramen magnum are reported. Among them 4 were cranio-spinal type and 8 spino-cranial type. Pathologically 4 were neuofibromas,3 meningio-mas, 2 lipomas, 1 astrocytoma, 1 ependymoma and 1 chordoma. Most patients manifested upper cervical nerve root symptoms. In the cranio-spinal type, impairment of IX X XI XII cranial nerves and slight pyramidal symptoms were often seen.In spino-cranial type, paralysis and loss of sensation were promi-nant.Lumbar puncture and Queckenstedt test were done in 8 cases, and in 7 cases there was obstruction of spinal canal. CT scans of the cranium and upper cervical region were performed in 12 cases, and in 11 cases space-occupying lesions were revealed. CT scan was negative in one patient, and the diagnosis was established by amipaque meylography. Operations were done in all cases. In 2 cases belonging to craniospinal type, tumors were totally removed, and in other 2 cases tumors were subtotally removed. In four cases of extramedullary spino-cranial type, tumors were tollally removed. In 4 cases of intramedullary tumors, only in one case the tumor (ependymoma) was totally removed by CUSA. There was no operative mortality in this series. The diagonsis, differential diagnosis and operative technics were discussed.
ABSTRACT
Twenty four cases of meningioma of the sphenoid ridge were reported. The common symptoms and signs of this tumor were summarized. For practical use, it may be classified as medial and lateral types. The symptoms and signs of these two types are different. Carotid angiograms are helpful to show the blood flow of the tumor. This method cannot be replaced by CT scan. The tumors were removed in fifteen patients totally, among them two died. The authors considered that the most important things for successful operation are to control bleeding carefully, to treat all the blood vessels at the base of the tumor properly and to protect its surrounding important structures during the operation.
