The incidence of pediatric adenoid hypertrophy increases year by year. However, the treatment methods are limited. By now TCM treatment has showed significant clinical efficacy in treating pediatric adenoid hypertrophy. And phlegm could be one of the main pathogenic factors. By collecting relevant literature about TCM treatment for pediatric adenoid hypertrophy, this article summarized the thoughts of treating from phlegm based on the collection and analysis of classification of syndrome and treatment methods guided by the thoughts of treating from phlegm.

BACKGROUND: Decoy receptor 1 (DcR1), which acts as decoy receptors, is resistant to apoptosis induction by related apoptosis inducing ligand (TRAIL). OBJECTIVE: To investigate the expression of the DcR1 (TRAIL-R3) protein in human herniated and normal lumbar intervertebral discs (IVD). METHODS: The expression and distribution of DcR1 proteins were assessed by using immunohistochemistry in 20 herniated lumbar IVD and 8 normal lumbar IVD tissues samples following discoidectomy from January to September 2010. RESULTS AND CONCLUSION: Percentage of nucleus pulposus and anulus fibrous cells with DCR1 expression was obviously more in the herniated group than in normal IVD group. The current results indicate that the expression of DCR1 rises after herniation.

Objective:To explore the preparation procedure of pediatric Kechuan black plasters. Methods:A single factor method was used to observe and study the preparation process of pediatric Kechuan black plaster from the following aspects: the selection of matrix raw material and refined equipment, and the temperature of refinery, “Xiadan”, pouring white wax and adding fine material powder in production processing. Results:The best temperature of“Xiadan” for pure sesame oil and mineral orange with the purity a-bove 95% was 313 ℃. The “Xianzha” temperature was 264 ℃, the temperature of “Houxia” was between 180 ℃ and 200 ℃, and white wax instead of the traditional method was used to eliminate fire toxin. Conclusion:The research is helpful to improving the quali-ty of the black plasters. The preparation process is stable and feasible, and suitable for the industrial production.

In this paper, duloxetine was chosen as the lead compound. The pharmacophores with 5-HT(1A) antagonism activity were used to replace the naphthyl of duloxetine. A series of duloxetine derivatives had been designed and synthesized and whose structures were confirmed with elemental analysis, MS and H NMR. All synthesized compounds were tested by tail suspension test and forced swimming test in vivo. The test results revealed that most of the compounds have shown better activity than duloxetine at the same dosage. Some of them are worth to be studied further.

OBJECTIVE To study the antidepressant effects of ammoxetine(AMX)and the underlying mechanisms. METHODS Two behavioral despair models,the tail suspension test (TST) and the forced swimming test(FST),were used to evaluate the antidepressant-like effects of AMX 2.5-20 mg · kg-1 following oral administration. Monoamine neurotransmitter p-chloro-phenylalanine(p-CPA)andα-methyl-p-tyrosine(AMPT) depletion models in mice were used to investigate the effects of AMX on levels of 5-serotomin(5-HT)and norepinephrine(NE)in the brain. RESULLTS The results of behavioral study showed that compared with normal control group,AMX(10 and 20 mg · kg-1)reduced the immobility time of mice by 51.4% and 80.7% in the TST(P<0.05,P<0.01) or by 48.0% and 66.2% in the FST (P<0.05),respectively. Locomotion activity test indicated that AMX did not increase or decrease the movement distance of mice,demonstrating that AMX had no excitatory or inhibitory actions on the central nervous system. Moreover,AMX(5,10 and 20 mg·kg-1)exerted antidepressant effects in the p-CPA induced 5-HT depletion model and AMPT induced NE depletion model,as evidenced by the significantly reduced immobility time,ie,63.9%,93.4%,90.5% and 61.9%,77.2%,100% reduction in the TST (P<0.01),respectively,and AMX at the dose of 20 mg·kg-1 significantly increased the concentrations of 5-HT and NE by 144.7% and 57.2% in the mouse brain(P<0.05) ,respectively. CONCLUSION AMX has strong antidepressant-like effects in behavioral despair models and monoamine neurotransmitter depletion models in mice,which is involved in the increased levels of 5-HT and NE in the brain.

BACKGROUND:Restoration of neurological functions after the damaged peripheral nerve is reconstructed is a hot topic in existing research. Within a short term fol owing peripheral nerve injury, nerve and muscle begin to develop irreversible degeneration. Restoration of the damaged nerve requires delayed degeneration and basic microenvironment. OBJECTIVE:To investigate the protective effect of cardiotrophin-1 on PC12 cells and Schwann cells. METHODS:Schwann cells and PC12 cells were obtained and cultured in complete medium, serum-free medium and 50 ℃ medium, respectively. cells in cardiotrophin-1 group were treated with exogenous cardiotrophin-1 solvent, while those in the control group were treated with equivalent Dulbecco’s modified Eagle’s medium, for 24 hours. The survival rate for PC12 cells and Schwann cells was determined using cellCounting Kit-8 colorimetric method. The lactate dehydrogenase activity in supernatant was detected by lactate dehydrogenase kit, and the malondialdehyde content and superoxide dismutase activity were measured by thiobarbituricaicd and xanthine oxidese method respectively. RESULTS AND CONCLUSION:The survival rate of PC12 cells and Schwann cells in cardiotrophin-1 group was obviously increased, lactate dehydrogenase releasing and malondialdehyde content were obviously decreased, superoxide dismutase activity was dramatical y improved compared with control group. Exogenous cardiotrophin-1 reduces the injury caused by ischemia and heat stress stimulation for PC12 cells and Schwann cells. The mechanism of protection may be related to the expression of anti-apoptosis protein activated by the combination of cardiotrophin-1 and its receptors.
