Objective To evaluate the therapeutic and adverse effects of metallic intratracheal stent placement in relapsing polychondritis with severe tracheobronchial malacia.Methods Five tracheal stents had been implanted in three patients with traeheobronchial malacia.One patient was implanted with two tubular steuts in trachea and one“Y”shaped stent for bilateral bronchi.Another patient used a tubular stent in total tracheal segment.The last patient used a tubular stent in the upper segment of trachea.Results All the stents were implanted successfully with obvious improvement of dyspnea after the treatment. Conclusions Metallic intratracheal stent placement can really relieve symptoms and improve the life quality in patients with tracheobronchial malacia caused by relapsing polychondritis.

OBJECTIVE To approach the distribution characteristic and drug resistance status in pathogens from infected urinary tract in Jingshan County and offer the scientific evidence for clinically reasonable use of antibiotics.METHODS Totally 218 strains of pathogens isolated from urinary tract were identified by routine methods according to the National Clinical Laboratory Operation Rules.Drug susceptibility testing was performed by K-B methods recommended by CLSI.RESULTS Among 218 strains of pathogens from infected urinary tract,Escherichia coli accounted for 61.0%,ranking the first and enterococci ranked the second,accounted for 11.5%.Except for 100% sensitivity to vancomycin and teicoplanin in Gram-positive bacteria and to imipenem and meropenem in Gram-negative bacteria,the pathogens from infected urinary tract had been resistant to commonly used antibiotics in some degrees.The detection rate of extended-spectrum beta-lactamases(ESBLs) producers was 32.9%.CONCLUSIONS The drug resistance in pathogens from infected urinary tract is on the rise.We should strengthen monitoring and controlling of it.

Litsea cubeba is one of aromatic medicinal plant belonging to family Lauraceae. The roots, stems and fruits of L. cubeba have been widely applied as folk medicines in some districts in China for relieving rheumatism and cold, regulating Qi (meridian) to alleviate pain. Previous studies revealed that this species contains major alkaloids, in specific aporphines, and minor flavonoids, lignans as well. Related pharmacological investigations demonstrated its activities and clinical applications on cardiovascular diseases, anti-cancer, against rheumatoid arthritis, relieving asthma and anti-allergic effects, as anti-oxidants, and so on. As an effort for further exploration of this bioactive ingredients and potential drug development, this paper summarizes most phytochemical and pharmacological results.

The purpose of this study is to explore depression metabolic markers in rat hippocampus and to investigate the anti-depressant effect of genipin and its mechanisms using nuclear magnetic resonance (NMR) metabonomics. Chronic unpredictable mild stress (CUMS) procedure was conducted to establish the depressive rat model. At the beginning of the third week, genipin low dose (25 mg x kg(-1)), middle dose (50 mg x kg(-1)), high dose (100 mg x kg(-1)), and venlafaxine (50 mg x kg(-1)) were given to the CUMS rats separately once daily for two weeks except control and model groups. Rat hippocampus was analyzed by 1H NMR based metabonomics after drug administration for 2 weeks. Significant differences in the metabolic profile of rat hippocampus of the CUMS treated group and the control group were observed with metabolic effects of CUMS including decreasing in glycine and N-acetylaspartate, increasing in inositol, glutamate, lactate, glutamine, taurine and alanine. Genipin showed ideal antidepressive effects at a dose of 50 mg x kg(-1) in rats, decrease of inositol, glutamate, lactate, alanine were observed, while glycine and N-acetylaspartate were increased. Important influence has been found on normal nervous system function of these significant changed metabolites, which suggests that the antidepressant effect of genipin may be played by enhancing the activity of neurons in hippocampus, repairing and improving the function of the neuron. The metabonomics approach is an effective tool for the investigation of the anti-depressant effect and pharmacologic mechanisms of genipin.

Objective This is the first study to explore clinical application value of serum Dickkopf-1 (DKK-1) detection in diagnosis of heptocellular carcinoma (HCC) by magnetic solid phase chemiluminescent immunoassay.Methods The level of serum DKK-1 and AFP in 205 cases of HCC,40 cases of liver cirrhosis,and 200 cases of healthy control were quantitatively detected by Magnetic solid phase chemiluminescent immunoassay.The area under ROC curve,sensitivity and specificity of DKK-1 and AFP for diagnosing HCC were calculated.Results The serum level of DKK-1 in HCC group was significantly higher than those of the liver cirrhosis group and healthy control group (P<0.01).DKK-1 maintained diagnostic sensitivity for patients with HCC who were alpha-fetoprotein (AFP) negative (66.3%).ROC curves showed optimum diagnostic cut-off value was 2.4 ng/mL,area under curve (AUC) was 0.822 (95% CI:0.783-0.856),sensitivity 65.9%,and specificity 87.5%).Moreover,measurement of DKK1 and AFP together improved diagnostic accuracy for HCC versus all controls compared with either test alone [AUC 0.915,95%CI:0.886-0.940),sensitivity 81.5 %(P<0.05)].Conclusion Serum DKK-1 detection has an important clinical value for diagnosis of HCC,especially for HCC with AFP negative.The combined detection of serum DKK-1 and AFP can greatly increase sensitivity and accuracy for diagnosing HCC.

Objective： This study was designed to investigate the effects of HMG-CoA reductase inhibitors on proliferation and growth of gastric cancer cells. Methods： MTT colorimetric assay and flow cytometry were used to measure the proliferative activity and the cell cycle progression of gastric cancer MNK450 cells. Results： Gastric cancer cells treated with Simvastatin had reductions in proliferative activity, S-phase fraction and proliferative index in a dose dependent manner with statistical significance at the concentrations of more than 1 μ mol/L as compared with normal control. The inhibitory rate ranged from 8.0％ to 51.5 ％ when cells were treated with Simvastatin at the concentrations of 0.2 -100 μ mol/L for 72 hours. Inhibition induced by Simvastatin was reversed by simultaneous addition of mevalonic acid at the concentation of 10 mmol/L. Gastric cancer cells were arrested by Simvastafin in G1 at the concentations of 1-20 μ mol/L. The fraction of S-phase cells was reduced from 32.1％ to 15.0％ after exposure to 20 μ mol/L Simvastatin for 36 hours. The addition of 10 mmol/L mevalonic acid overcome G1 arrest induced by 5 μ mol/L Simvastatin. Otherwise, the percentage of cells in G2 plus M2 remained rather constant throughout the treatment. Meanwhile, Pravastatin had no significant effect on the proliferatiive activity of gastric cancer MNK450 cells. Conclusion： Simvastatin could inhibit the proliferation and growth of gastric cancer cells, which suggests that Simvastatin has the effect of antitumor.

A phytochemical investigation on the aerial parts of a Tibetan medicine Meconopsis horridula, by solvent extraction, repeated chromatographies on silica gel, Sephadex LH-20, and preparative TLC techniques, led to the isolation of 9 compounds.

Objective To investigate the pathogenesis of osteoarthritis and feasibility of acupotomy therapy through the observation on the influences of acupotomy therapy on ethology and morphology in rabbits with knee osteoarthritis.Methods The model of knee osteoarthritis was established by applying the fixed method of knee extension posture in rabbits. The therapy of electro-acupuncture and acupotomy therapy were used to treat the rabbits. After 3 weeks the knee joint function was observed and reviewed based on Lequesne algofunctional index. The light microscope was used to observe tibia tissue after HE staining. The transmission electron microscope (TEM) was used to observe the internal femoral condyle cartilage.Results Lequesne algofunctional index showed that in local reaction, gait reaction and joint motion there was a significant different between the electro-acupuncture group or acupotomy group and the normal group or model group (P<0.05), respectively, while there was no different between the electro-acupuncture group and acupotomy group (P>0.05). HE staining showed that the cartilage injury was relieved and tended to recovery in the electro-acupuncture group and acupotomy group. The result of TEM showed that the lesion of cartilage cells and disorder of collagen fibrils were relieved in the acupotomy group, which is similar to those in the electro-acupuncture group.Conclusion The acupotomy therapy has a good curative effect on knee osteoarthritis, which is proved at macroscopic and microscopic levels.
