4.Clinical effect of compound anisodine on patients with paralytic strabismus and the influence on malondialdehyde and superoxide dismutase
International Eye Science 2016;16(10):1902-1904
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.
5.Cardiac electronic pacemakers and biological Pacemakers
Chinese Journal of Tissue Engineering Research 2008;12(9):1787-1792
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.

International Journal of Cerebrovascular Diseases 2013;(2):143-147
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.
9.Advance of clinicopathological and molecular research of triple negative breast cancer
China Oncology 2013;(8):603-608
Triple negative breast cancer (TNBC) is characterized by the lack of expression of hormone receptors, as well as human epidermal growth factor receptor 2 and displays special biological and clinicopathological characteristics. This subtype is aggressive in nature with high histological grade. Besides invasive ductal carcinoma,several special histological types have also been found. The features of the TNBC subgroup roughly parallel those of the basal-like subgroup. Due to the lack of molecular targets, this subgroup has no chance of endocrine treatment and target therapy. Currently, the treatment of TNBC is dominated by chemotherapy based on anthracycline with suboptimal efficacy. Overall, the prognosis has remained quite poor. Emerging evidence indicates that patients regimens with triple negative breast cancer usually displays high rate of early recurrence and distant metastasis. Both the diseasefree survival and overall survival rates are low. Although this subtype which shows same immunohistologic pattern, great heterogeneity still exists within the group causing distinctions in morphology, prognosis, and more importantly, drastically different reactions to same treatment protocol. In recent years, TNBC has been widely concerned by both clinician and pathologist. Several targeted drugs for corresponding signal pathway as well as the subtype of triple negative breast cancer have been widely studied. This article focused on the advances in clinicopathological characteristics, new subtypes and treatment of triple negative breast cancer.

Chinese Journal of General Surgery 2013;28(9):705-708
Objective To investigate the effect of early embryonic mouse pancreatic tissue transplantation in the treatment of mouse experimental diabetes.Methods C57BL/6 mouse models of streptozocin-induced diabetes mellitus were established and then randomly divided into two groups:transplantation group,in which,five to seven pieces of pancreatic tissue of mice at embryonic 16.5 days were transplanted into mouse renal capsule,and sham-operated (SO) control group,in which,0.05 ml RPMI1640 culture medium was injected into mouse renal capsule.When blood glucose level of the transplantation group mouse was ≤ 11.2 mmol/L,the endocrine function of embryonic pancreatic tissue transplanted was detected by IPGTT and IPITT methods and then the transplanted graft was removed for observing the blood glucose surge.In vitro,levels of insulin secretion were measured in serum,E16.5 pancreatic tissue and graft (3.3 mmol/L and 16.7 mmol/L) glucose stimulation by ELISA.Histology and immunohistochemistry were observed before or after pancreatic tissue transplantation to detect insulin and glycagon production.Results (1) The glucose level decreased significantly in the TX group after 4-6 weeks of transplantation (13.4 ± 6.5 vs 28.9 ± 2.5,P < 0.05),and the body weight gaining (P < 0.05).Compared to SO group,glucose level decreased significantly (P < 0.001).The graft can modulate insulin secretion; (2) Insulin can be detected in E16.5 embryonic mouse.Insulin and glycagon were produced more in TX group than pretransplantated pancreatic tissue.Conclusions E16.5 embryonic mouse pancreatic tissue transplantation effectively controls serum glucose level and restore the nondiabetic pattern of weight gaining in diabetic mouse.
