1.Treatment for locally advanced pancreatic cancer
Journal of International Oncology 2013;40(11):850-853
Combined therapy consisting of radiotherapy,chemotherapy and palliative surgery is the primary management for locally advanced pancreatic cancer,with the purpose of prolonging survival and improving life quality.Gemcitabine is the standard chemotherapy at present.Gemcitabine-based combinations show a definite effect,and the combination with targeted drugs also has a certain degree of efficacy.The development of new chemotherapy drugs and targeted drugs provides more ways for the teatment of locally advanced pancreatic cancer.
2.Progress in the study of leptin and childhood obesity
Journal of Medical Postgraduates 2003;0(11):-
Leptin,a proteohormone primarily made by adipocytes,directly interacts with the hypothalamus for energy balance regulation.It plays an important role in the morbility of obesity.The soluble leptin receptor(sOb-R) is one of the leptin receptor isoforms.The examination of the sOb-R concentration is valuable because of its function in the regulation of leptin concentration.Leptin shows a great potential as a childhood obesity biomarker,and its concentration could be used in assessing the responsiveness of obese children to intervention programs.
3.Gut microbiota and type 1 diabetes mellitus
International Journal of Pediatrics 2017;44(3):189-192
Recent researches have shown that gut microbiota play an important role in pathogenesis of immune-related disorders.Type 1 diabetes mellitus,as an autoimmune disease,has received increasing attention,especially in terms of the relationship between the pathogenesis and intestinal microbiota.Change of gut microbiota is an important risk factor of the pathogenesis of type 1 diabetes mellitus which have been confirmed with the animal model studies.This article reviews the role of gut microbiota in the pathogenesis of type 1 diabetes mellitus,and the influence of gut microbiota on host immune response for possible prevention and treatment of type 1 diabetes mellitus in the future.
4.Role of calcium signaling in neoplasms invasion and migration
Journal of International Oncology 2014;41(3):161-164
Intracellular calcium is one of the crucial signalings that modulate various physiological and pathological processes.Abnormal calcium signaling is closely associated with invasion and migration of neoplasms.Calcium regulates focal adhesion turnover,cytoskeletal reorganization and other processes about tumor cell movement through contacting with multiple downstream proteins,such as calpain,PYK2 and S100 protein family.Several calcium entry channels including store-operated calcium channels and transient receptor potential channels participate in the invasion and migration of tumor cells.Pathological calcium signaling may be a potential target in anti-invasion and anti-migration therapy.
5.Effects of recombinant human erythropoietin on the expression of glutamine synthetase of cultured retinal Müller cells under high glucose condition
Chinese Journal of Ocular Fundus Diseases 2013;29(5):514-517
Objective To investigate the effect of recombinant human erythropoietin (rhEPO) on the expression of glutamine synthetase (GS) of cultured rat retinal Müller cells in high glucose environment in vitro.Methods Mtüller cells were isolated from retinas of 10 Sprague-Dawley rats at postnatal day three to five by trypsin digestion,and were randomly divided into six groups,including normal control group,high glucose group,high glucose +5 U/ml rhEPO group,high glucose+ 10 U/ml rhEPO group,high glucose+ 20 U/ml rhEPO group,high glucose+40 U/ml rhEPO groups.After 48 hours,the apoptosis of retinal Müller cells were assayed by terminal transferase-mediated DNA end labelling assay,and the expression levels of GS protein were detected with semi-quantitative immunocytochemistry.Results Compared with the normal control group,the cell viability and GS protein were reduced while the cell death increased in Müller cells cultured in high glucose,the difference was statistically significant (t =27.4,P < 0.01).Compared with the high glucose group,rhEPO treatment reduced the apoptotic Müller cells (t=857.2,2 374.6,2 473.2,2 537.7; P<0.01),induced the expression of GS proteins (t=3.2,18.0,22.5,26.4; P<0.05).Conclusions rhEPO can protect Müller cells from apoptosis under high glucose condition.The mechanism may be related to its function to up-regulate the GS protein expression,promote glutamic acid cycle,and reduce the excitotoxicity effects of high concentration of glutamate.
6.Diagnostic values of transrectal ultrasound-guided puncture biopsy in prostate carcinoma:a report of 238 cases
Journal of Clinical Surgery 2014;(8):592-594
Objective To discuss the diagnostic values of transrectal ultrasound-guided puncture biopsy in prostate carcinoma(PCa).Methods A total of 238 patients with suspected PCa received tran-srectal ultrasound-guided puncture biopsy.Results Based on the results of biopsy pathology,88 cases (37.0%)were diagnosed as PCa,105 cases(44.1%)were benign prostate hyperplasia,15 cases (6.3%) were low-grade prostatic intraepithelial neoplasm,17 cases(7.1%)were atypical hyperplasia,8 cases(3. 4%)were adenomatoid tumor,and 5 cases(2.1%)were granulomatous prostatitis.Conclusion Tran-srectal ultrasound-guided puncture biopsy is accurate and safe.It is an effective method in diagnosing pros-tatic carcinoma.
7.Combine library and institute of information: The development model of institute of resources-information
International Journal of Traditional Chinese Medicine 2012;34(9):812-814
This paper presents a development model of resource information institute from organic integration the institute of information and library.The all data of resources-information institute come from and serve for theoretical research,clinical practice,and scientific research of TCM.Comparing with usual research institute and library,the resource information institute has five dominant positions,which are subjects,scientific researches,resource,professionals and services.
8.EML4-ALK fusion gene in non-small cell lung cancer
Journal of International Oncology 2012;(11):848-850
EML4-ALK fusion oncogene represents a new molecular target which appears mainly in lung adenocarcinoma.EML4-ALK is detected more frequently in young non-small-cell lung cancer patients who never or light smoke.ALK inhibitors(crizotinib)for the treatment of the EML4-ALK-positive non-small cell lung cancer has a high response rate.This finding can improve the individual treatment of non-small cell lung cancer.
9.Demand analysis and training mode discussion of personnel talents of TCM informatics
International Journal of Traditional Chinese Medicine 2013;35(4):332-334
Informatics of traditional Chinese medicine is an emerging subject.This dissertation analyzes the connotation and scope of the study of traditional Chinese medicine informatics.Through investigating the demand for personnel talents of Chinese medicine hospital and Information Institute of TCM,we comment on with what theoretical basis and practical abilities the TCM information personnel talents should possess.It also proposes the training mode and optimization measures of TCM Informatics education.
10.Study on free anthraquinone and conjugated anthraquinone of Radix et Rhizoma Rhei and its processed product roasted by wine extracted by different solution
Chinese Traditional Patent Medicine 1992;0(01):-
AIM: To explore the relationship of the decrease of the catharticizing action and the conjugated anthraquinone after Radix et Rhizoma Rhei was in the process of stirred-fry-with wine by comparing the content of conjugated anthraquinone among different processing Radix et Rhizoma Rhei in the solution decocted by water and extrected by methanol. METHODS: The spectrophotometer was used to assay the content of free anthraquinone and conjugated anthraquinone of different proccssing Rudix et Rhizoma Rhei in the solution decocted by water and extracted by methanol. RESULTS: In the solution decocted by water there was little difference in free anthraquinone between the raw and the processing products, however, the conjugated anthraquinone of the precessing product was much higher than the raw. CONCLUSION: The decrease of the conjugated anthraquinone can’t fully account for the reduction of the catharticizing action of Radix et Rhizoma Rhei in the process of stirred-fry with wine. The real cause needs to be explored in many aspects.
