1.New mode of competing endogenous RNA: circular RNA
Chinese Critical Care Medicine 2016;28(5):466-468
Circular RNA (circRNA) is widely found in various species' cells.They have several characteristics including structural stability,high expression and expression in a tissue-specific manner.Recent studies have demonstrated that circRNA is a member of competing endogenous RNA (ceRNA).CircRNA regulate the expression of related RNA molecules via binding with target microRNA (miRNA) and play an important role in gene expression and regulation.The finding of circRNAs not only expand our understanding about eucaryon and ceRNA regulation network,but also indicate that circRNA might be a new biological marker for diagnosis and has good application prospects in drug development research,and disease diagnosis and treatment.Because current research on circRNA is still very few,a brief summary about circRNA is presented in this paper for further research.
2.Research progress of chromosomal abnormalities in non-Hodgkin's lymphoma
Journal of Leukemia & Lymphoma 2012;21(5):315-317
Non-Hodgkin's lymphoma (NHL) is a heterogeneous disease from various resources and biological characters. Currently, about 90 % of NHL is relative to chromosomal abnormalities. This review emphasizes chromosomal abnormalities in non-Hodgkin's lymphoma, which can not only help understanding NHL genesis,but also is useful for diagnosis on early stage and proper treatment.
3.Crohn's disease: medical treatment and role of nutritional support
Chinese Journal of Clinical Nutrition 2010;18(4):203-208
Crohn's disease (CD) is a chronic granulomatous disease with unknown causes, and its incidence shows a rising trend in China. So far there is no way for the complete cure of the disease. Conventional drug therapy has many limitations. The appearance of biological agents brings new treatment options for CD and also initiates a debate over "Step-up" versus "Top-down" strategies. Rational nutrition supplement plays an important role in the comprehensive treatment of CD. This paper reviews the efficacy of conventional drugs, new progress in drug therapy, roles and status of nutritional support, and new treatment strategies for CD.
4.Progress in prevention and treatment of parenteral nutrition associated cholestasis of preterm infants
International Journal of Pediatrics 2011;38(1):59-61
In the treatment of parenteral nutrition(PN) of preterm infants, parenteral nutrition associated cholestasis(PNAC) is the most common complication. However, the mechanisms of how this complication happens are unknown. This paper summarizes the research reports about PNAC both at home and aboard in recent years and raises various precautions on premature birth avoiding, reasonable feeding, PN projects optimizing and so on.Ursodeoxycholicacid is the first-line drug in the current treatment for PNAC.
5.The expression of interferon induced protein 10(IP-10) and Th1/Th2 cytokines in the peripheral blood mononuclear cells of ankylosing spondylitis patients
Medical Journal of Chinese People's Liberation Army 1983;0(05):-
Objective To investigate the role of IP-10 in the pathogenesis of ankylosing spondylitis (AS). Methods The peripheral blood monocytic cells (PBMC) were collected from 39 AS patients, and the mRNA expression of IP-10, IFN-? and IL-4 were measured by semi-quantitive RT-PCR with G3PDH as the internal control. Results The mRNA expression levels of IP-10, IFN-? and IL-4 as well as the rate of IFN-?/IL-4 were elevated in the PBMC of AS patients compared with the healthy controls (P
6.CT Findings of the Ovarian Endometriosis Cyst
Journal of Practical Radiology 1992;0(11):-
Objective To discuss the CT findings of the ovarian endometriosis cyst.Methods CT findings of 15 cases ovarian endometriosis cyst confirmed by patology were retrospectively analyzed.Results There were 20 cysts in 15 cases.Their CT features were as follow:(1)CT values varied from watery to hemoid.(2)They had a irruglar outer fringe and a regular inner fringe without noduls.(3)Septations were seen in the cysts.(4)The characteristic feature was that daughter cysts lied outside of mother cysts.(5)The wall of cysts could be enhanced regularly.Conclusion CT plays an important role in the diagnosis of this disease.
7.Progress in free fatty acid receptor GPR40
Chinese Journal of Endocrinology and Metabolism 2001;0(05):-
The G protein-coupled receptor, GPR40, is a specific receptor for free fatty acids. Singnaling pathways are activated in islet ?-cells by fatty acids as binding to GPR40. Fatty acids regulate insulin secretion and cause ?-cell hyperplasia through GPR40. GPR40 also mediates responses to antidiabetic drugs like thiazolidinediones. GPR40 agonists and/or antagonists show potential effect in the development of new anti-diabetic drugs.
8.Determination of Plasma Concentration of Duloxetine by LC-MS
China Pharmacy 2001;0(08):-
OBJECTIVE:To develop an LC-MS method for the determination of the concentration of duloxetine in human plasma.METHODS:Plasma sample(0.2 mL)was taken,with the protein precipitated twice using acetonitrile.The mobile phase consisted of 20 mmol?L-1 ammonium acetate(pH3.5)-methanol-acetonitrile(38∶20∶42).The sample was separated on a Thermo C18 column with plasma concentrations(time-concentration profile)of duloxetine in 10 healthy volunteers determined by LC-MS after taking a single oral dose of duloxetine enteric-capsule(22.4,44.8 or 67.2 mg).RESULTS:The calibration curve of duloxetine was linear over the concentration range of 0.78~100 ng?mL-1(r=0.999 5)with the recovery at 100.8%,the RSD of intra-day and inter-day at no more than 7.8% and 9.3%,respectively.CONCLUSION:The method developed in our study was proved to be accurate and sensitive,and suitable for the pharmacokinetic study of duloxetine.
9.Thoughts and methods of study on acupuncture medical history: an example of Mr. MA Ji-Xing.
Chinese Acupuncture & Moxibustion 2014;34(3):303-307
Mr. MA Ji-xing has devoted himself into the study of acupuncture medical history for more than 70 years. As a result, a great work of Zhenjiuxue Tongshi (see text), History of Acupuncture-Moxibustion) has been completed. The author has expensively studied for history of acupuncture medicine in time and space. Base on abundant historical materials, deliberate textual research as well as strategically situated academic view, it is considered as a masterpiece of acupuncture on real significance. It is worthwhile to note that the book has a systematic and profound explanation on Bian-stone therapy, unearthed literature relics of acupuncture, the bronze figure or illustration of acupoint as well as special topics of Japan and Korea acupuncture history. Filled several gaps of the field, and explored some significant new paths of study, it laid the groundwork for the profound study and unscramble of traditional acupuncture theory as well as the investigation of the academic history, which is considered to have a profound and persistent influence. The careful sorting and profound digging of many distinguish thoughts and methods of Mr. MA Ji-xing in the study of acupuncture medical history has significant meaning in references and enlightenment of the future research on acupuncture medical history.

10.Application and effect of FOCUS-PDCA methodology on the control of catheter-related blood stream infection
Chinese Journal of Infection Control 2014;(7):425-427,437
Objective To evaluate the effect of FOCUS-PDCA program(find,organize,clarify,understand,se-lect,plan,do,check,act )on the prevention and control of catheter-related blood stream infection (CRBSI)in an intensive care unit(ICU).Methods Process of central venous catheterization and nursing care were analyzed by u-sing FOCUS-PDCA program,and the causes for CRBSI were found out ;a continuous quality improvement (CQI) team was established to provide training for ICU nurses,and the process was improved and supervised,virtuous cir-cle was created.Results Incidence of CRBSI decreased from 8.29‰ before FOCUS-PDCA intervention(January-December,2010)to 3.20‰ after FOCUS-PDCA intervention(January 2011 -December 2012),the difference was significant (χ2 =14.6,P <0.001).Conclusion FOCUS-PDCA program is effective for controlling the incidence of CRBSI.
