AMP-activated protein kinase (AMPK) is an important regulator of cellular energy homeostasis. Recent studies demonstrated that AMPK is a novel signaling molecule modulating inflammatory responses and oxidative stress which are involved in inflammatory pulmonary diseases, such as asthma, chronic obstructive pulmonary disease (COPD), pulmonary infectious diseases and pulmonary fibrosis. AMPK attenuates inflammatory lung injury by phosphorylating its downstream targets, such as sirtuin1 (SIRT1), peroxisome proliferator-activated receptor gamma coactivator-1alpha (PGC-1alpha), p53 and forkhead box O3a (FoxO3a). This review summarized the relationship between AMPK and the development of inflammatory pulmonary diseases.

[Objective]To study the effects of different storage method on the viability of cheodroeytes so as to find out the idem method for preservation of articular cartilage.[Method]Under the aseptic condition,acquiring 240 pieces of osteoehondral plugs from both condyles of femur and tibial plateau.The control group was not treatment using any preserved means.The tissue-cultured group was to used F12-DMEM medium long-term preserved osteochondral plugs under the conditions of 37 ℃.At preserve 8 weeks,takes the osteochondral section to carry on examination observation ohondrocytes Viability activeness change separately.[Result]The control group chnadrocyte survival rate was 94.4%.At preserves 8 weeks,the cell survival rate of the tissue-cultured group was 76%,the grading-cooling cryopreservation group was 66%,the constant-cooling cryopreservation group only was 41.80%.[Conclusion]Under the condition of 37 ℃,tissue culture method can long term preservation of vital articular cartilage in vitro.The chondrocyte survival rate of the preservation of vital articular cartilage in vitro.The chondrocyte survival rate of the tissue-cultured method obvious higher than constant-cooling cryopreservation method.

Objective:To investigate the mechanism of indoleamine 2,3-dioxygenase(IDO)in HepG2 cells contributing to tumor immune escape.Methods:T-lymphocyte and HepG2 cell were cocultured,and 1-methyl-tryptophan(1-MT)was added to make an intervening experiment.The expression of IDO mRNA in HepG2 cell cocultured with T-lymphocyte was detected by RT-PCR;the apoptosis rate of HepG2 cell cocultured with T-lymphocyte was analyzed by flow cytometer;The cytotoxicity of T-lymphocyte against HepG2 cell was examined by MTT assay.Results:In combine reaction system,the expression of IDO mRNA was strongly induced in HepG2 cell cocultured with T-lymphocyte and faintly induced when cultured with 1-MT;the earlier apoptosis rate of HepG2 cell in control group and experiment group(1-MT:1.25 mmol/l,2.5 mmol/l,5mmol/l)was respectively(3.48?0.34)%,(7.82?0.41)%,(18.62?0.42)%,(25.32?0.40)%(P

[Objective] To observe the effect of different acupoint application therapies :a summer treatment for the winter disease on allergic rhinitis ,and compare the relationship between the different acupoints and therapeutic effect. [Methods ] The 81 cases of allergic rhinitis who met inclusion criteria were divided into 12 acupoint group and 6 acupoint group. The time of application was in first ten-day period of the hot season. The duration of application was 2h. The days later, namely in the second ten-day period of the hot season, and twenty days later, in the third ten-day period of the hot season, the application was repeated respectively. Before treatment and half year after the treatment, the score of quality of life, symptoms of allergic rhinitis were observed to compare the relationship between the different acupoints and therapeutic effect. [Results] The effective rate was higher in 12 acupoints group than 6 acupoints group. After treatment, the score of quality of life, symptoms of allergic rhinitis were significantly improved( P<0.05 or P<0.01). And the comparison of the therapeutic effect of two groups showed significant difference in statistics( P<0.01). [Conclusion] The acupoint application therapy is effective for allergic rhinitis, and the comprehensive combination of acupoint is influential on the effect.

Objective To observe the clinical efficacy of the combination of western medicine with acupuncture for treatment of polycystic ovary syndrome (PCOS) of infertility.Methods Totally 120 PCOS patients were randomly divided into western medicine group and acupuncture group, 60 cases in each group. All patients took Diane-35, and with whom resistant to insulin were added with Metformin. At the meantime patients increased the amount of exercise with adjustment and control of everyday diet. After three periods, the western medicine group used the method of Clomifene Citrate with Chorionic Gonadotropin to help ovulation induction. The acupuncture group used the method of acupoint selection including invigorating spleen and kidney with adjusting qi and blood to promote ovulation. The level of FSH, LH, FINS, E2 and T of the two groups were observed before and after treatment.Results After treatment, the levels of T, FINS, LH and BMI in the two groups decreased, with statistical significance (P<0.05). The levels of T and BMI in the acupuncture group were lower than the western medicine group after the treatment, with statistical significance (P<0.05). The total efficiency, gestation number, number of high-quality follicle, and basal body temperature of acupuncture group were all higher than the western medicine group, with statistical significance (P<0.05).Conclusion The combination of western medicine with acupuncture for treatment of PCOS of infertility has confirmed efficacy.

ObjectiveTo investigate the expression of E-cadherin and β-catenin in the primary colorectal carcinoma and metastatic lymph nodes and it's clinical significance. MethodsImmunohistochemical analysis of Ecadherin and β-catenin was performed in colorectal mucosa( n =20 ,group A) ,colorectal carcinoma without metastasis ( n = 25, group B) and colorectal carcinoma with metastatic lymph nodes ( n = 39, group C) The expression of E-cadherin and β-catenin and the metastasis and prognosis of colorectal carcinoma were observed. ResultsThe strongly positive expression of E-cadherin in primaries of group C (5.1％ ) was obviously lower than in group B ( U = 2. 149,P =0. 032) ,whereas no statistic differences of the expression of E-cadherin between primaries and metastases of group C were observed(P =0.186). There was no difference of the expression of β-catenin between group B and group C,the same of primary colorectal carcinoma and self control lymph nodes of group C(P =0.235 and P =0. 715). There was positive correlation between membranous down regulation of E-cadherin and β-catenin in group C( r = 0.387 ,P =0.024) ,but no relationship was found in group B( r = 0.080 ,P = 0.723 ). ConclusionThe decreased membranous expression of E-cadherin in the colorectal carcinoma was correlated with lymph nodes metastasis, and was obviously related to membranous down regulation of β-catenin. There was no relevance between the expression of β-catenin and the lymph nodes metastasis of colorectal carcinoma.

Objective To explore the efficacy of microvascular decompression (MVD)on trigeminal neuralgia and the anatomical characteristics of the responsible blood vessels.Methods The clinical data of 25patients with idiopathic trigemine neuralgia(ITN) undergoing MVD were analyzed retrospectively.The origins of the responsible blood vessels and sites of compression at the trigeminal root were observed and determined.Meanwhile,the anatomical characteristics of the responsible blood vessels and the efficacy of MVD were investigated.Results The offending vessels which were responsible for ITN were identified at root exit zone (REZ) in 21 cases (84％).The most common responsible vessel was the superior cerebellar artery in 13 cases (52％),followed by anterior inferior cerebellar artery in 6 cases (24％).Seventy six percent of the offending vessels were arteries and 8％ were rock vein.No vascular compression but evident increase in the thickness of arachnoid mater covered by the trigeminal nerve was observed in 4 cases ( 16％ ).All patients were relieved for the acute pain and the overall cure rate was 96％.Conclusion MVD is a safe,microinvasive and effective surgical modality for ITN.The key for better outcomes and less complications of MVD is to improve microsurgical techniques and deal with all the involved vessels.
