Objective: To compare the curative effect of Fritillariae Cirrhosae Bulbus (FCB) in six species from five origins on recurrent asthma in mice. Methods: Eighty one female Kunming mice were randomly divided into nine groups with equal weights, such as model, control, Dexamethasone (DEX, positive control), and six FCB groups. The mice in the model, DEX, and FCB groups were sc injected with ovalbumin (OVA) on days 1, 7, and 14, then challenged with the aerosols of normal saline contained OVA on days 22-28. The mice in DEX and FCB groups were ig administered with DEX (0.6 mg/kg) and FCB (830 mg/kg) respectively for 28 d, and the mice in the control group were given 0.1% carboxymethyl cellulose. The surface tension of bronchoalveolar lavage was measured, the lung tissues were taken for hematoxylin-eosin (HE) staining, and the tracheal stenosis and volume difference of pulmonary alveolus were analyzed by the microphotograph. Results: Compared with the control group, the tracheal stenosis, surface tension, and volume difference of pulmonary alveolus were increased obviously in the model group (P < 0.01). The pathological section revealed vessel wall thickening in bronchiole, inflammatory cell infiltrating, gland hyperplasia, and mucus hypersecretion, but FCB could reverse these pathological changes (P < 0.01). Each FCB had its feature to cure asthma. F. unibracteata and F. delavayi had the most potency on increasing alveolar surfactant; F. unibracteata and F. taipaiensis had the most potency on attenuating tracheal stenosis; F. unibracteata and F. przewalskii had the most potency on relieving the inflammation; F. unibracteata and F. taipaiensis had the most potency on reducing glandular hyperplasia or intimal thickening. Each FCB had its feature to cure asthma, but F. unibracteata was the best. Conclusion: FCB has the best potency to prevent and cure the recurrent asthma in mice, but each FCB has its feature. The diversity of FCB species should be protected.

Based on the demand of nasal drug delivery high drug loadings, using the unique phase transfer of solute, integrating the phospholipid complex preparation and submicron emulsion molding process of Scutellariae Radix extract, the study obtained the preparation of the high drug loadings submicron emulsion of Scutellariae Radix extract.

Objective To investigate the preventive effects of aspirin on liver metastases of colorectal cancer in mice and study the mechanisms.Methods Twenty BALB/c mice were divided into the control group and the experimental group according to the random number table with 10 mice in each group.Mice in the control group were fed with saline each day at a concentration of 0.2 mL/d for 60 days,while mice in the aspirin group were fed with aspirin each day at a concentration of 30 μg/(g · d) for 60 days.Then C26 colon cancer cells were injected into the spleen and then the spleen was cut to establish mice model of colon cancer liver metastasis.The C26 colon cancer cells were divided into 2 groups.C26 colon cancer cells in the control group remained untreated,and C26 colon cancer cells in the experimental group were treated with aspirin at a concentration of 10 mmol/L for 24 hours.The scratches and transwell assays were conducted to observe the effects of aspirin on the invasion and metastasis of C26 colon cancer cells.The expressions of epithelial-mesenchymal transition (EMT)-related genes were detected using RT-PCR and Western blot.All data were analyzed using the Student t test.The survival curve was drawn by Kaplan-Meier method,and the survival analysis was done by Log-rank test.Results The numbers and weights of hepatic metastatic tumors were 4.8 ± 1.9 and (504 ± 107) mg in the control group and 2.6 ± 1.6 and (362 ± 67) mg in the experimental group,with significant difference between the 2 groups (t =2.840,3.584,P ＜ 0.05).The 1-month survival rate was 80％ in the experimental group,which was significantly higher than 40％ of the control group (x2=4.418,P ＜ 0.05).The results of pathological examination showed that tumor cell heteromorphism was reduced by aspirin.The results of scratches experiment showed an obvious migration of C26 colon cancer cells in the control group at 24 hours later,while no C26 colon cancer cells migrated in the experimental group.The numbers of C26 colon cancer cells penetrated the Watrige were 253 ± 21 in the control group and 148 ± 13 in the experimental group,with significant difference between the 2 groups (t =5.101,P ＜0.05).The relative mRNA expression of the E-cadherin and the Vimentin were 0.002 ±0.001 and 1.005 ±0.286 in the control group and 0.005 ± 0.001 and 0.270 ± 0.168 in the experimental group,with significant difference between the 2 groups (t =-4.606,4.942,P ＜ 0.05).The relative protein expressions of the E-cadherin and the Vimentin were 0.473 ±0.179 and 0.787 ± 0.118 in the control group and 1.585 ± 0.410 and 0.280 ± 0.133 in the experimental group,with significant difference between the 2 groups (t =-5.542,6.355,P ＜ 0.05).Conclusion Aspirin inhibits liver metastasis of colon cancer and promote the survival ratio of mice.Aspirin can up-regulate the expression of E-cadherin and down-regulate the expression of Vimentin,which inhibits EMT and reduces the invasion and metastasis of tumor cells.

OBJECTIVE:To determine serum concentrations of western medicines in patients treated with "traditional Chinese antiepileptic medicine" alone and to evaluate the curative effects.METHODS:A total of 60 epileptic patients who visited our hospital between Feb.1997 and June 2006 were subjected to plasma drug level monitoring and during which the patients were treated with "traditional Chinese antiepileptic drugs" alone.Plasma concentrations of 4 kinds of western medicin-es were determined by FPIA.RESULTS:Of the 60 cases,valproic acid,carbamazepine,phenytoin and phenobarbitone were detected in 18,40,41,and 47 cases/times,respectively.On average,more than two kinds of western medicines were detected in every patient,and the blood concentrations were mostly beyond effective plasma drug concentration.The total curative effects were unsatisfactory.CONCLUSION:The fact that western medicine ingredients detected in these traditional Chinese antiepileptic medicines is inconformity with medication principle of epilepsy.Traditional Chinese antiepileptic medicines should be used with caution in the clinic in the treatment of epileptic patients.

Objective To investigate the effects of nasal tip reduction with inner incision combined with external fixation,namely,to evaluate the formation of bilateral alar groove which is en hanced by external fixation with small splints,after removing interdomal fat pad as well as adjusting alar cartilage to reduce nasal tip.Methods Alar cartilage and interdomal fat pad were exposed via the bilateral nasal vestibular incision to remove fat pad and part of enlarged lateral foot of alar cartilage.After suture of incision,based on the tissue removal,plastic splint was used for external fixation of bilateral nasal tip and alar groove for one week,to enhance the formation of alar groove.Results A total of 143 patients were followed up for more than 6 months after operation.Photographs taken before and after operation were compared,suggesting obviously smaller nasal tip and significant alar groove.Left and right alar groove space was decreased from preoperative (28.23±3.31) mm to post operative (23.72±2.65) mm,and nasal tip alar angle was decreased from (104.02±9.57)°to (87.78± 6.98)°,with statistical significance (P＜0.05).Slightly asymmetric nasal alars were found in 6 patients during follow-up examination,while tiny scars caused by splints (at 0.6 cm from the edge of splints) were found in 1 patient.Conclusions On the basis of nasal tip reduction with inner incision,the method of suture with small splints combined with external fixation is simple,effective and available.

BACKGROUND:Polysulfone membrane holds good anti-biodegradation ability, but how to use it to prepare hol ow fiber dialysis membrane and its blood compatibility have not been ful y understood. OBJECTIVE:To study the preparation, transfer property and biocompatibility of hol ow fiber dialysis membrane. METHODS:With polysulfone as the film material, diethylene glycol as the porogen, polyvinyl pyrrolidone as the modifier, N, N-dimethylacetamide as the solvent, and the hol ow fiber dialysis membrane was prepared using nonsolvent-induced phase separation. The performance was measured using scanning electron microscopy, ultra-depth three-dimensional microscope imaging and porosity test;the transfer parameters including reject rate and water flux were detected by ultrafiltration device;the blood compatibility was determined through hemolysis test, dynamic clotting time test and platelet adhesion test. Type II medical polyurethane material served as negative control. RESULTS AND CONCLUSION:The section of hol ow fiber dialysis membrane was asymmetric. 17%dialysis membrane showed a porous middle layer, while 19%, 21%and 23%membrane showed a sponge-like middle layer. Under the same membrane area, the density of fiber dialysis membrane was significantly lower than that of the negative control material, and the porosity of fiber dialysis membrane was significantly higher than that of the negative control material (P<0.05). The water volume and water flux of the hol ow fiber dialysis membrane were significantly higher than those of the negative control material (P<0.05). Results from three hemolytic tests showed that the average absorbance values and hemolysis rate of the hol ow fiber dialysis membrane were significantly higher than those of the negative control material (P<0.05). The dynamic clotting time test and the platelet adhesion test revealed that the dynamic clotting time of hol ow fiber dialysis membrane at 20, 40 and 70 minutes was significantly shorter than that of the negative control material (P<0.05). These results suggest that polysiloxane can be used as the membrane material to prepare hol ow fiber dialysis membrane using nonsolvent-induced phase separation, and holds a good biocompatibility, blood compatibility and transfer efficiency.

Objective To investigate the relationship between the apolipoprotein B (ApoB) gene Xba Ⅰ and EcoR Ⅰ polymorphisms and cholelithiasis in Han and Mongolian population in the Midwest Area of Inner Mongolia.Methods The clinical data of 100 patients with cholelithiasis and 115 healthy individuals at the First Affiliated Hospital of Medical College of Baotou from April to October in 2010 were collected.A case-control study which detected ApoB alleles of patients with cholelithiasis (cholelithiasis group) and healthy individuals (control group) in Han nationality and Mongolian nationality in the Midwest Area of Inner Mongolia was conducted by polymerase chain reaction-restriction fragment length polymorphism,which included Xba Ⅰ (X + X +,X + X-,X-X-,X +,X-) and EcoR Ⅰ (E + E +,E-E-,E + E-,E +,E-).The serum lipid (including triglyceride,total cholesterol,high density lipoprotein and low density lipoprotein) levels in different groups were detected.The count data and the measurement data were analyzed using the chi-square test and t test,respectively.Results Genotype X + X + was not found in the Han and Mongolian population,and Xba Ⅰ (X +) or EcoR Ⅰ (E-) alleles was not found in the Mongolian population.The levels of low density lipoprotein were (2.8 ± 0.9)mmol/L in the cholelithiasis group,which was significantly higher than (1.9 ± 0.8) mmol/L of the control group in the Han population (t =2.800,P ＜ 0.05).The levels of high density lipoprotein and low density lipoprotein were (1.7 ± 0.3) mmol/L and (3.5 ± 0.8) mmol/L of the cholelithiasis group,which were significantly higher than (1.2 ± 0.3) mmol/L and (2.8 ± 0.9) mmol/L of the control group in the Mongolian population (t =7.596,2.549,P ＜ 0.05).The levels of triglyceride,total cholesterol,high density lipoprotein and low density lipoprotein of the cholelithiasis group in the Mongolian population were (3.1 ± 1.6) mmol/L,(5.6 ± 1.0) mmol/L,(1.7 ± 0.3) mmol/L and (3.5 ± 0.8) mmol/L,which were significantly higher than (1.2 ± 0.6) mmol/L,(4.4 ± 1.2) mmol/L,(1.3 ± 0.3) mmol/L and (2.8 ± 0.9) mmol/L of the cholelithiasis group in the Han population (t =5.501,3.667,4.448,3.430,P ＜ 0.05).The levels of triglyceride,total cholesterol,low density lipoprotein were (2.6 ± 1.7) mmol/L,(5.1 ± 1.1) mmol/L and (2.8 ± 0.9) mmol/L of the control group in the Mongolian population,which were significantly higher than (1.3 ±0.7)mmol/L,(3.9 ±0.9) mmol/L and (1.9 ±0.8) mmol/L of the control group in the Han population (t =4.298,4.772,3.888,P ＜ 0.05),while the level of high density lipoprotein was significantly higher of the control group in the Han nationality than the control group in the Mongolian population (t =1.997,P ＜ 0.05).The levels of low density lipoprotein in patients with genotypes X + X-,X-X-of the cholelithiasis group in the Han population were (2.7 ± 0.1) mmol/L and (2.6 ± 1.0) mmol/L,and the levels of low density lipoprotein in patients with genoeypes E + E ±,E + E-/E-E-were (2.6 ± 1.0) mmol/L and (2.5±0.4)mmol/L,with no significant difference (t=0.225,0.124,P＞0.05).Conclusion In the Midwest area of Inner Mongolia,the Mongolian population might be more susceptible to cholelithiasis than the Han population.No relationship between the rare alleles X +,E-and the increase of blood lipids,which indicates that X + and E-of ApoB may not be a risk factor of cholelithiasis.
