Objective To study chronic bronchitis rats oxidant/antioxidant related indicators Ho flavored Dingchuan Decoction.Methods 50 SD rats were adopted improved smoked method to make chronic bronchitis model.From the 20th day of the modeling,blank control group and model control group gavage were treated with saline.The positive control group were treated with Cough Mixture.The experimental groupwere dealed with Ho flavored Dingchuan Decoction high,medium and low-dose.20 day later,the cotent of SOD,CAT,MDA in rat serum,lung tissue and balf were observed.Results Compare to blank control group,the cotent of SOD[(188.11 ± 9.37)U/ml、(276.11 ±30.28) U/ml,(8.80 ± 1.49)U/ml],CAT[(9.40 ±2.04)U/ml,(26.57±4.26)U/ml,(1.58±0.26) U/ml] in rat serum,lung tissue of the experimental group significantly reduced (P ＜0.01) ; MDA [(5.64 ± 0.52) μmol/L,(6.32 ± 2.10) μmol/L,(28.08 ± 2.43) μ mol/L) increased (P ＜0.05 or P ＜ 0.01).Ho flavored Dingchuan Decoction can effectively reverse these changes,and showed a significant dose-dependent.The Ho flavored Dingchuantang,in middle and high-dose serum SOD [(253.05 ± 7.81) U/ml,(256.92 ± 5.37)U/ml],CAT [(14.86 ± 2.49)U/ml,(18.22 ± 2.65)U/ml] higher than those of blank control group.And the Ho flavored Dingchuantang,in middle and high-dose lung tissue SOD [(470.91 ± 11.46)U/mgprot,(482.91 ± 14.32)U/mgprot),CAT [(46.87 ± 3.75)U/mgprot,(55.49 ±3.33)U/mgprot] higher than those of blank control group.Content close to the normal level.Conclusion The Ho flavored Dingchuan Decoction has significantly reduce the oxidative stress in chronic bronchitis.

AIM: To investigate the clinical effect of compound anisodine on patients with paralytic strabismus and the influence on malondialdehyde ( MDA ) and superoxide dismutase ( SOD) .
●METHODS: Seventy cases diagnosed with paralytic strabismus from Jun. 2008 to Dec. 2014 were selected as treatment group; another 70 cases with paralytic strabismus from Oct. 2000 to Jan. 2008 were chosen as control group. The control group was given with conventional therapy, and treatment group was additionally injected with compound anisodine subcutaneously on the basis of the control group. Treatment lasted for two courses about 28days. The effect of compound anisodine on patients with paralytic strabismus was evaluated and the serum level of MDA and SOD was also measured before and after treatment.
●RESULTS: ln treatment group, 54 cases were cured (77%), 14 cases improved (20%) and 2 cases had no response ( 3%) and total efficiency reached to 97%. ln control group, 32 cases were cured ( 46%) , 21 cases improved ( 30%) and 17 cases had no response ( 24%) and total efficiency was 76%. The cure rate and total efficiency of treatment group were significantly higher than that of control group (P<0. 05). Before treatment, the level of SOD and MDA was equal in two groups. After treatment, increased SOD level and decreased MDA level was observed in both groups. However, compound anisodine were significantly increased SOD level and reduced MDA level when compared with conventional therapy (P<0. 05).
●CONCLUSION: The compound anisodine shows the beneficial effect on patients with paralytic strabismus. Compound anisodine may exert the effect via increasing SOD and reducing MDA.

Objective To observe clinical effect of Chinese medicine combined chemotherapy in the treatment of elderly patients with advanced non-small cell lung cancer. Methods 61 cases of elderly patients with advanced non-small cell lung cancer patients were randomly recruited into two groups. 30 cases in treatment group, which was treated with Chinese medicine combined single-drug chemotherapy, 31 cases in control group, which was treated with Chinese medicine combined combination-chemotherapy. After 42 days of 2 cycle, the clinical effect of both groups was observed. Results The treatment group was superior to the control group on improvement of quality of life, symptomatic improvement, the toxicity of chemotherapy and treatment costs. The difference between the two groups were significant (P< 0.05) . Conclusion Chinese medicine combined single-drug chemotherapy in the treatment of elderly patients with advanced non-small cell lung cancer is superior to combined combination-chemotherapy.

This paper described the progress of treating elderly patients with advanced non-small cell lung cancer both domestically and abroad. The advantages of Chinese medicine and Chinese medicine combined with chemotherapy were emphasized.

BACKGROUND: The implantation of electronic devices has become the preferred treatment tor symptomatic bradyarrhythmias.However,there are many shortcomings in electronic pacemakers.The usage of molecular biology principle to develop biological pacemaker has become a topic of discussion in research.When sinoatrial node is lnhlblted,pacemaker effect runs by transfecting hyperpolarization-activated cyclic nucleotide-gated(HCN)channel gene of If current,overexprcssing HCN,and increasing inward current in diastolic phase of the heart.Construction of biological pacemakefs by gene therapy and cell therapy may become an optimal substitute of electronic pacemakers in the near future.OBJECTIVE:To sum up the research advancement in application of HCN channel gene to the development of biological pacemaker.RETRIEVAL STRATEGY:The relevant articles published between January 1979 and June 2007 were searched for in Pubmed database by researcher of this article with the key words of"hyperpolarization-activated cyclic nucleotide-gated chartnel,biological pacemaker"in English.157 articles were selected and reviewed by the inclusive cntena of:① articles closely related with the application of HCN to the development of biological pacemaker;②the late articles and articles in anthority journals in the same field.Exclusive criterion:repetitive studies.LITERATURE EVALUATION:The main sources of literatures were randomized clinical trial(RCT)on biological pacemaker by HCN.Among 36 selected articles,10 were reviews,and others were elementary expenInental studles.DATA SYNTHESIS:①Of all four HCN isoforms,HCNI,HCN2,and HCN4 are the main isoforms in the heart.HCN3 only expresses in embryonic pacemaker cells in a low level.HCN2 highly expressed in low pacing regions(Ventricular muscle),whereas HCN4 highly expressed in high pacing regions.Moreover,HCN2 are the main isoforms in the ventricle.Expression ratio of HCN2 to HCN4 is 5:1 in neonate rats and 13:1 in adult rats.②Defects in HCN channels may underlie sick-sinus syndrome.③Up to now,HCN genes of If current contribute importantly to the generataon of the regular pacemaker potential.CONCLUSION:Gene therapy and cell therapy have become an optimal approach to improve biological paccmakers.Application of HCN channel gene in development of biological pacemaker may hold great promlse In the treatment of chronic arhythmia.

Homebox genes are known to determine cell proliferation and differentiation and subsequently regulate the occurrence,development and prognosis of many tyhpes of malignant tumors in human.Some recent studies have shown that homebox genes are abnormally expressed in the esophageal,gastric,coloreetal and other gastrointestinal tumors.In this review,we consider that homebox genes may regulate the occurrence,development of gastrointestinal tumors by interacting with transcription factors in vivo and abnormal epigenetic modifications.Therefore,homebox genes are closely related to gastrointestinal tumors.

PI3K/Akt pathway is a biological signal transduction pathway activated by phosphatidylinositol 3-kinase (PI3K).It plays a key role in cell proliferation,cell-cycle regulation,apoptosis initiation,and angiogenesis.In addition,the PI3K/Akt pathway is closely associated with the protection mechanisms of central nervous system damage.In-depth study of PI3K/Akt,downstream molecules and their regulation mechanisms,can provide some new ideas and methods for the treatment of brain injury.
