Objective To observe the clinical effect of Futongning Granules for the treatment of functional abdominal pain in children. Methods A total of 187 children with functional abdominal pain were randomized into treatment group(N = 122)and control group(N = 65). The treatment group was treated with Futongning Granules and the control group was treated with Compound Pepsin Powder. The gastrointestinal syndrome scores of the two groups were observed, and the short-term and long-term clinical efficacy of the two groups was evaluated after treatment. Results (1)The total effective rate and the effective rate for syndromes of abdominal internal cold, spleen-stomach deficiency cold, indigestion induced by milk and food stagnation, liver-Qi stagnation, blood collateral obstruction, gastrointestinal heat stagnation in the treatment group were 92.3%, 92.9%, 95.0%, 95.2%, 90.3%, 85.7%, 90.0%, and those in the control group were 71.0%, 69.2%, 69.2%, 86.7%, 66.7%, 50.0%, 60.0%, respectively. The total effective rate and the effective rate for various syndromes in the treatment group were superior to those of the control group (P < 0.05). (2) After treatment, gastrointestinal syndrome scores of various syndromes and overall scores in the two groups were obviously decreased(P<0.05 or P<0.01 compared with those before treatment), and the decrease in the treatment group was superior to that in the control group (P < 0.05). (3) The results of 6-month follow-up showed that the clinical efficacy during the follow-up in the treatment group was better than that in the control group(P < 0.05), and the difference was statistically significant(P<0.05). Conclusion Futongning Granules exert certain effect for the treatment of functional abdominal pain in children, and are effective for significantly relieving clinical symptoms and reducing the recurrence of disease.

OBJECTIVETo study the effects of acute cold exposure on the inflammation and pathologic injuries in pulmonary of rats, and explore the mechanism induced by cold stress.
METHODSForty male Wistar rats were randomly divided into five groups(n = 8): control group (23 ± 2) °C 2.5 h, -25°C 0.5 h group, -25°C 1 h group, -25°C 2 h group and -25°C 2.5 h group. Rats were exposed to cold at -25°C and no wind by keeping them in a low temperature chamber except control group. Rectal temperatures of the rats were measured before and after cold exposure. The morphological changes of pulmonary were observed by the optics microscope. The levels of tumer necrosis factor-α(TNF- α), interleukin-6 (IL-6) and interleukin-β (IL-1β) in lung tissue homogenate were measured by ELISA.
RESULTSCompared to the control group, body core temperatures of the -25°C 1 h group, -25°C2 h group and -25°C 2.5 h group were decreased significantly, and the D-values of rectal temperature were increased before and after cold exposure (P < 0.05). The infiltration of inflammatory cells and alveolar edema fluid appeared in the lung tissue of the -25°C 2.5 h group. The concentrations of tumor necrosis factor-α (TNF α), interleukin-6 (IL-6) and inter- leukin-1β (IL-1β) in lung tissue homogenate were increased significantly in -25°C l h group, -25°C 2 h group and -25C° 2.5 h group (P < 0. 05).
CONCLUSIONThe infiltration of inflammatory cells and the increase in proinflammatory cytokine from pulmonary may lead to the lung tissue injury after acute cold exposure.

Objective To observe the expression of vimentin (Vim) after silence of interleukin-1β (IL-1β) in rats with spinal cord contusion (SCC). Methods The model of SCC was established in 30 Sprague-Dawley rats with Allen's method. The rats were randomized into vector group (n=15) and silence group (n=15), which were injected blank lentivirus vector and vector of IL-1β siRNA, respectively; and divided in three, seven and 28 days subgroups. The relationship between IL-1βand Vim was predicted with GeneMANIA bioinformatics. The expression of Vim protein and mRNA in spinal cord was detected with immunohistochemistry and real-time quantitative polymerase chain reaction. Results GeneMANIA bioinformatic analysis indicated that there was some direct and indirect relationship between IL-1β and Vim. The Vim protein and mRNA expressed in the spinal cord, and was less in the silence group than in the vector group (t>2.875, P<0.05). Conclusion Silence of IL-1β can inhibit the expression of Vim in SCC rats, which may promote the recovery of spinal cord function.

Background RGD is a small molecular multiple peptide containing Arg-Gly-Asp with an important role in inhibiting the adhesion,migration and neovascularization of tumor.Our previous study determined that RGD can suppress the adhesion and proliferation of lens epithelial cells(LECs),and RGDRGD may be of a stronger effect. Objective Present study was to investigate and compare the effect of RGDRGD peptide on the proliferation and adhesion of immortalized human LECs(HLEB-3)in vitro. Methods Human LECs harvested by trpsin-EDTA were suspended in DMEM medium with serial dilutions of RGD peptide and RGDRGD peptide(from 1000 mg/L to 250 mg/L)at 37℃ for 15 minutes as experimental group,and the HLECs cultured by common culture medium were used as the control group.The cells were then seeded into the 96-well plates with precoated fibmnectin (FN)and I collagen at the density of 2×104/ml.MTT stainingcolorimetry was used to measure the adhesion rates of lens epithelial cells cultured in different concentrations RGDRGD and RGD peptides after 1 hour.Cells were seeded into the 96-well plates for 24 hours at 37℃ in 5% CO2.Medium was then replaced with DMEM overnight.Subsequently,the cells were treated with serial dilutions of RGD and RGDRGD(from 2000 mg/L to 250 ms/L)dissolved in DMEM medium plus 20% fetal bovine serum.The inhibition of RGDRGD and RGD on the adhesion and proliferation of Human LECs was analyzed by MTT aher 24,48 and 72 hours. Results The inhibition rate of RGD peptide on the adhesion of LECs was gradually enhanced with the increase of concentration with the significant difference among the different concentrations groups(F=1089.56,P<0.01),and the statistically significant elevation in inhibitory rate was found in RGDRGD peptide compared with RGD peptide(P<0.01).The inhibition rate of RGDRGD peptide on the proliferation of LECs wag gradually increased with the increase of concentration with the significant difference among the different concentrations groups with a strongest effect in 1000 ms/L group(F=127.31,P<0.01),and the much stronger inhibition Wag Been in RGDRGD peptide(F=1589.85,P<0.01).The suppression rate of RGDRGD on LECs proliferation Wag much stronger with the prolong of time(F=1606.43,P<0.01). Conclusion RGDRGD peptide and RGD peptide have inhibitory effect on adhesion and proliferation of human LECs in a dose-and time-dependent manner.Effect of RGDRGD peptide is much stronger than RGD peptide.These results imply that RGDRGD peptide and RGD peptide have the important role for prevention of PCO.
