Objective:To investigate the clinical effects of dermatophagoides farinae drop combined with Bailing capsules in the treatment of allergic rhinitis. Methods:Totally 96 patients with allergic rhinitis in our hospital were selected and randomly divided into two groups with 48 cases in each by a randomization table. The patients in the treatment group received dermatophagoides farinae drop and Bailing capsules,and those in the control group only received dermatophagoides farinae drop. The scores of symptoms and physical signs and adverse reactions were compared between the two groups. Results:After the treatment,the scores of symptoms and physical signs in the two groups were significantly decreased(P < 0. 05),and the decrease in the treatment group was more notable(P < 0. 05). The effective rate of the treatment group(93. 75% )was higher than that of the control group(62. 50% ,P <0. 05),while the incidence of adverse reactions of the two groups was without significant difference(P > 0. 05). Conclusion:Bailing capsules combined with dermatophagoides farinae drop can significantly relieve the clinical symptoms and signs,and improve the quality of life of the patients with allergic rhinitis,which is worthy of promoted application in clinics.

Objective To investigate the clinical efficacy and prognosis of transcatheter arterial chemoembo-lization(TACE)combined with radiofrequency ablation(RFA)in treatment of liver cancer.Methods 64 patients of liver cancer were selected as the research subjects,and they were divided into two groups by randomized single blind method.32 cases in the control group adopted the TACE treatment,while 32 cases in the observation group were given TACE combined with RFA.The tumor shrinkage,complete necrosis rate,local recurrence rate,AFP levels and adverse reactions of the two groups were compared.The patients were followed up for 3 years to record survival.Results After treatment,the tumor shrinkage rate and complete necrosis rate of the observation group were 90.63% and 75.00%, which were significantly higher than 68.75% and 50.00% of the control group,the differences were statistically significant (χ2 =8.453,8.203,all P <0.05).The local recurrence rate of the observation group was 21.88%,which was significantly lower than 43.75% of the control group,the difference was statistically significant(χ2 =7.887,P <0.05).After treatment,the AFP level of the observation group was (70.11 ±6.45 )ng/L,which was significantly lower than (157.76 ±10.42)ng/L in the control group,the difference was statistically significant (t =7.433,P <0.05).The survival rates of 1 year,2 years and 3 years in the observation group were 84.38%,71.88%,56.25%, which were significantly higher than 65.63%,53.13%,31.25% in the control group (χ2 =8.677,8.203,8.985,all P <0.05).The incidence rate of postoperative adverse reaction had no significant difference between the two groups (χ2 =1.337,P >0.05 ).Conclusion TACE combined with RFA in treatment of liver cancer can significantly improve the effect of tumor necrosis rate,reduce the local recurrence rate and prolong the survival time of the patients, and it had less adverse reaction,higher safety,and which should be applied in clinical.

Objective To prove the mechanism of diethylstibestrol(DES) induced abnormal spermatogenesis,this study on the changes of proto-oncogenes bcl-2 and p53 proteins as well as cadherin adherens molecules expression in adult male hamster spermatogenic cells. Methods Adult male golden hamsters were treated daily olive oil vehicle either alone(control)or containing 1 mg/kg body weight of DES (experiment)by subcutaneous injection for 7 days.The changes of testes histological morphology were observed under light and electron microscope.The expressions of bcl-2 and p53 and cadherin in the testes seminiferous epithelium were detected by immunohistochemistry. Results DES induced adult hamster testes abnormal spermatogenesis.As compared to the control group animals,in DES-treated group animals the expression of both bcl-2 and p53 significantly increased in spermatogenic cells,especially in spermatocytes and round spermatids.However,the expression of cadherin adherens molecules obviously decreased.Conclusion It is one of reasons of DES inducing abnormal spermatogenesis that DES can result in increasing in the expression of proto-oncogenes bcl-2 and p53,and reducing cadherin adherens molecules expression.

Objective To study the effects of Chinese herb extracts on cell proliferation and glucose absorption in intestinal epithelial cell line(IEC-6 cells) of rats.Methods The extracts of four Chinese herbs,including Herba Agastaches(HA),Rhizoma Atractylodis(RA), Cortex Phellodendri(CP),and Gypsum Fibrosum(GF),were made.Their suitable concentration on the cell proliferation in IEC-6 cells was determined by MTT method,and glucose absorption and the activity of Na+,K+-ATPase in IEC-6 cells were assayed.A method of real time PCR was applied to the determination of SGLT1 and GLUT2 mRNA expression in the cells.Results Chinese herb extracts treatment altered the cell proliferation in a dose-dependent manner.Moreover,RA volatile oil(50 ?g/mL) and CP alkaloid(10 ?g/mL) treatment increased glucose absorption and the activity of Na+,K+-ATPase genes(P0.05).Conclusion The three extracts treatment,including RA volatile oil,CP aklaloid,and HA volatile oil,could increase glucose absorption and the expression of glucose transport carrier genes,but their regulative mechanism are not totally the same.

ObjectiveTo evaluate whether oral administration of Chinese tradiational medicine,Qing-Xue granula,can prevent mouse lung injury caused by thoracic radiation.Methods128 BalB/C mice were divided into 4 groups:control (C) group; radiation (R) group; radiation plus high dose Qing-Xue granula (H) group and radiation plus median dose Qing-Xue granula ( M ) group.The H and M groups were fed 0.64 g and 0.32 g of Qing-Xue granula dissolved in 0.5 nl anline once daily for two months,which were 4 and 2 times of human dosage,respectively.Whole thorax radiation of 12 Gy was delivered with a single ventral-dorsal field with 6 MV X-ray.Group C and group R received 21 days of 0.5 ml saline feeding.Mice were sacrificed at 1,2,4 or 6 months after radiation. Macrophage cell count of lung lavage fluid and hydroxyproline content of left lung were assayed,and the lung fibrosis was scorred according to the Ashcroft's criteria.The plasma interleukin-6 (IL-6) and vascular endothelial growth factor (VEGF) concentration were assayed with ELISA method.The One-way ANOVA was used to test the significance of any differences between groups at each time point. Results The macrophage cell number of lung lavage fluid was significantly lower in the 1st month in group M than in group R (2∶4,q =3.92,P ＜ 0.05 ),but had no significant difference between group M and C ( 1 ∶ 4,q =2.13,P＞0.05 ).The hydroxyproline content of group H was significantly lower than group R in the 1st and 6th months (q =3.62,3.54,all P ＜ 0.05 ),but still higher than group C ( q =4.09,3.72,all P ＜ 0.05 ).The fibrosis score of group H was significantly lower than group R in the 2nd,4th and 6th months (q=3.38 -4.16,all P＜0.05).The IL-6 concentration of group H was significantly lower than group R in the 1st month ( q=3.53,P＜0.05 ),but not significantly higher than group C (q =1.41,P＞0.05).The VEGF concentration was significantly higher in group R than group C since the 2nd month ( q =3.12 - 3.78,P ＜ 0.05 ).The VEGF concentration was significantly higher in group H and M than group R in the 2nd and 6th months ( q =3.08 - 3.92,all P ＜ 0.0 5 ).Conclusions Oral Chinese traditional medicine,Qing-Xue granula,could prevent radiation induced lung fibrosis in mice,especially at high dosage.The degree of elevation of VEGF in plasma was not parallel with that of lung fibrosis.

Objective To develop a scoring system to determine peptic ulcer risks and to evaluate its screening efficiency.Methods A total of 862 people who underwent gastroscopy for the first time ranging from 18 to 45 years old were enrolled in this study.They were divided into two cohorts with the method of simple random sampling,514 in the original cohort and 348 in the validation cohort.Information such as demographic characteristics,dietary intake,lifestyle,symptoms relating to peptic ulcer was obtained.A multivariable logistic regression method was used to determine independent predictors of peptic ulcer.Based on the logistic regression model,a scoring system was developed with a regression coefficient-based scoring method.Then the scoring system was internally and externally validated.Each value of calibration,discrimination and accuracy were computed and then compared with those of original cohort to assess its screening efficiency.Results Three variables (gender,smoking and melena) composed the scoring system with scores ranging from 0 to 4 points.It had good calibration (P =0.956) and discrimination (area under the ROC =0.70,95％CI:0.65-0.76).With 2.5 points as the screening cutoff value,the sensitivity,specificity,accuracy rate,positive predictive value,negative predictive value,positive likelihood ratio and negative likelihood ratio were 49.5％,82.2％,75.5％,41.6％,86.4％,2.78 and 0.61,respectively.In the validation cohort,the sensitivity,specificity,accuracy rate,positive predictive value,negative predictive value,positive likelihood ratio and negative likelihood ratio were 27.2％,92.7％,71.3％,64.6％,72.3％,3.89 and 0.79.The results above indicated that the screening efficiency of the scoring system in the original cohort was similar to that in the validation cohort.Conclusion The scoring system to determine peptic ulcer risks,containing gender,smoking and melena,has good screening efficiency and can be applied to predict the risks of peptic ulcer.

Objective To explore the effect of apolipoprotein E deficiency on astrocyte destruction in the ex vivo spinal cord slice model. Methods Vibratome-cut transverse spinal cord slices from C57BL/6 postnatal day 7 ApoE -/-mice and wild-type mice were cultured on transwell porous supports. After 7 days in the culture , spinal cord slices were exposed to LPS for 5 days. The expression of AQP4, GFAP and Iba1 was detected by immunofluorescence. The concentration of TNF-α and NO were detected by ELISA and method of nitrate reductase, respectively. Results Marked loss of AQP4 and GFAP staining were shown in LPS-affected groups, not in the control group, and the lesion score was higher in ApoE-/-group than WT-group (P<0.05). In addition, the expression of Iba1 and concentration of TNF-α, NO in the LPS-affected groups were more than that of the control group (P < 0.05), and they were higher in the ApoE-/-LPS group than the WT-LPS group (P < 0.05). Conclusions ApoE deficiency exacerbates astrocyte injury, likely through promoting the release of pro-inflammatory mediators from microglia.

AimTo study the effects of glipizide and met formin on the serum IGF-1,IGF-2 in patients with type Ⅱ diabetes mellitus; Methods The effect of glipizide(n ＝ 40) and metformin(n ＝ 25) on serum IGF-1, IGF-2 in patients with type Ⅱ diabetes mellitus were compared with self- controlled study. Results In metformin-treated patients ,there were not significantly changes in fasting IGF-1 and IGF-2 concentrations, In glipizide-treated patients, there were markedly increased IGF-1 concentrations(181.8+ 104.5) vs (209.0+ 88.2) ng· ml-1(P＜0.05) while serum IGF-2 was not change. There was a significant reduction of blood glucose in two groups at the end of treatment(both P＜0.01), but C-peptide level was markedly increased(P＜0.05) only in glipizide-treatedpatients.Conclusion The changes of IGF-1 is markedly different between metformin-treated and glipizide-treated patients with type Ⅱ diabetes mellitus.

Objective This study aimed to investigate the incidence and the cause for duodenalbiliary reflux and reflux cholangitis after metallic stent placement in distal common bile duct Methods After percutaneous transhepatic bile duct puncture and biliary outside drainage was performed, 16 cases with malignant distal biliary stricture underwent metallic stent placement in distal common bile duct Before stent placement, the routine laboratory studies including leukocyte, neutrophil percentage and the levels of total bilirubin and direct bilirubin in blood were performed for all patients. Two to five days [ an average of (3.3 ±0. 9) days ] after stent implantation, the above indexes were tested again, and 1 ml of water containing 185 MBq of 99Tcm-DTPA was given orally before extubation, then 99Tcm radioactivity in the bile was detected 2 hours later. For the measurement data obtained from the experiment, t test or Wilcoxon signed rank test was adopted to compare them, and P ＜ 0. 05 was considered to be statistically different Results In 14 cases, radioactivity was successfully detected in the bile 2-5 days after stent implantation. Twelve of them was detected to have radioactivity in the bile 2 hours before extubation with duodenal-biliary reflux. The technetium count in the bile accounted for 1.82% of the total intake dose. There was no radioactivity in the bile in 2 cases. In 14 patients, there were no symptoms of cholangitis such as high fever, chills, increased jaundice, and so on after stent implantation. The mean of white blood cell count was (7.59 t2. 62) × 109/L, and the median of neutrophil percentage was 0. 74. Compared with those before stent implantation, the difference did not reach statistical significance ( t = 0. 423, Z = 1. 036, P ＞ 0. 05 ).After stent implantation, the median of total bilirubin and direct bilirubin were significantly lower, which were 92. 2 and 74. 3 μmol/L. Compared with those before stenting,the difference was statistically significant (Z= -3. 170, -3. 170, P ＜0.05). Conclusions There is a high incidence of duodenal-biliary reflux after stent implantation in distal common bile duct in the early stage. However, there is no simultaneous cholangitis caused by duodenal-biliary reflux.
