1.Influence of enhanced patient education on the patients' knowledge and awareness of peripherally inserted central catheter
Chinese Journal of Clinical Nutrition 2013;21(5):313-315
Objective To explore the usefulness of enhanced patient education in increasing the patients' knowledge and awareness of peripherally inserted central catheter (PICC) protection.Methods Totally 200 patients with PICC in Neijiang First People's Hospital from June 2009 to June 2012 were divided into control group (odd numbers,conventional patient education,n =100) and observation group (even numbers,enhanced patient education,n =100) according to their admission numbers.The patients' knowledge and awareness of PICC protection were analyzed after treatment,and the incidences of adverse events and catheter indwelling time were also compared between these two groups.Results Compared with the control group,the observation group had significantly higher PICC protection knowledge rate (91% vs.78%,P =0.001),awarehess rate (95% vs.80%,P=0.011),lower incidence of adverse events (1% vs.5%,P =0.034),and longer PICC indwelling time [(125.8 ± 10.6) d vs.(106.7 ±8.2) d,P =0.026].Conclusion Enhanced patient education can effectively enhance the patients' knowledge and awareness of PICC protection.
2.Discussing on bringing conductive education into the compulsory course of rehabilitation ther-apy related majors
Chinese Journal of Medical Education Research 2014;(1):52-54
Conductive education is an education system aiming at helping the handicapped people improve the impaired and abnormal function through education. This article started from the current status of conductive education in clinical rehabilitation and analyzed the causes for imbalance between supply and demand of conductive education professionals. Meanwhile strengthening and ex-panding the coverage and strength of general conductive education was proposed and bringing con-ductive education into the compulsory course of rehabilitation therapy major was recommended. Finally, training conductive educational professionals with high-quality was regarded as the most fundamental measure to solve these problems.
3.Effect and mechanism of ligustrazine on the airway smooth muscle of isolated guinea pigs
International Journal of Pediatrics 2014;(5):544-547
Objective To observe the effect and mechanism of Ligustrazine ( LIG ) on the Airway smooth muscle( ASM) of isolated guinea pigs. Methods The normal guinea pig bronchus were made into tra-chea spiral,and randomly divided into LIG group, LIG+Propranolol group, LIG+Atropine, LIG+Nifedipine group,LIG+Glibenclamide group and the control group. The effect of different concentrations of LIG on the ASM was respectively observed in the resting tension and the high tension caused by histamine,and the ASM re-laxation rate were compared between each groups. Results (1)It had diastolic function for LIG on the isolated guinea pigs ASM in the resting tension and the high tension caused by histamine. (2)In the resting tension,com-pared with the group LIG,the diastolic function was antagonism by the concentration of LIG 10-7 ~10-6. 5 mol/L in the group LIG+Propranolo (P<0. 05). The diastolic function had no significant difference by the concentra-tion of LIG 10 -7.5 ~10 -3 mol/L in the group LIG+atropine and LIG+Glibenclamide(P>0. 05). The diastolic function was improved remarkably by the concentration of LIG 10 -6 ~10 -4 mol/L,in the group LIG+Nifedip-ine (P<0. 05). (3)In the high tension caused by histamine,compared with the group LIG,the diastolic function was antagonism obviously by the concentration of LIG 10 -6. 5 ~ 10 -5 mol/L in group LIG+Propranolol ( P<0. 05);The diastolic function had no significant difference by the concentration of LIG 10 -8 ~10 -3 mol/L in group LIG+atropine,and LIG+Glibenclamide (P>0. 05);The diastolic function was improved remarkably by the concentration of LIG 10 -6.5 ~10 -5 mol/L in group LIG+Nifedipine (P<0. 05). Conclusion It has dias-tolic function for LIG on the isolated guinea pigs ASM in the resting tension and the high tension caused by his-tamine. The effect and mechanism may be related with the competitive exciting beta 2 receptor and the inhibitor of Ca2+ internal flow. It provides a theoretical basis for the clinical application of LIG in treating asthma.
4.Investigation and Analysis of Dose-Related Items in Drug Package Inserts
China Pharmacy 2005;0(19):-
OBJECTIVE:To provide reference for standardization of drug package.METHODS:5 dose-related items stated in a total of 426 package inserts of chemical drugs collected from the drug storeroom in our hospital were investigated and analyzed.RESULTS:Only 32.39% of the package inserts were with complete labeling.The labeling rate for special group was low and only 40% labeled the maximal dose.Less than 2% of child dose stated the doses according to body surface area,and the problem of over-dose was common.Only 27.46% had the item of "under supervision of a physician".CONCLUSION:It is necessary to strengthen supervision on drug package inserts and improve cognition on the importance of drug package inserts.
5.The transdifferentiation of Sca-1~+ cells from murine fetal liver
Chinese Journal of Pathophysiology 2000;0(12):-
AIM: To explore transdifferentiation potential of Sca-1 + cells from murine fetal liver. METHODS: 2?10 3 of Sca-1 + cells from male murine fetal liver were transfused into female mouse irradiated lethally with ? ray from 60 Co source (10 Gy) via tail vein. Two months later, FISH and immunohistochemistry were used to detect the situation for transdifferentiating of the donor cells (male cells) in tissues of female recipient mouse. RESULTS: The renal tubular epitheliocyte-like and neurocyte-like cells with Y chromosome were found on the sections of renal and brain tissues from female recipient mice. These cells have phenotype characteristics of RCA+/CD - 45 F - 4/80 and NueN +/CD -45 F - 4/80, respectively. CONCLUSION: The evidence is provided for Sca-1 + cells from murine fetal liver to transdifferentiate into both renal and brain tissue cells.
6.Nutrition Status of Premature Neonates in Early Postnatal Stage in Neonatal Intensive Care Unit
Journal of Applied Clinical Pediatrics 2006;0(14):-
Objective To study the nutrition status of premature infants in the early postnatal stage.Methods According to the physical development standard,the premature neonates for treatment in our NICU from Jun.2007 to Jun.2009 were enrolled and divided into normal growth group and extrauterine growth restriction(EUGR) group.The nutrition status of these premature neonates were evaluated respectively.SPSS 13.0 software was used to analyze the data.Results Compared with EUGR group,the durations of regaining birth weight were shorter in normal growth group(t=-13.83,P0.05).Conclusions Premature neonates are prone to encounter extrauterine growth retardation.Extrauterine growth retardation had great impact on premature neonates.Premature neonates should be strengthened with nutrition supplement in order to reduce the incidence of extrauterine growth retardation.

10.Progress in the research on 21-gene Oncotype Dx in breast cancer prognosis
China Oncology 2009;19(12):953-958
Currently the most effective treatment strategy for breast cancer is standardized multi-discipline comprehensive treatment. However, there are no effective models that can accurately predict prognosis, so that no guidance of individualized treatment has yet been set up, resulting in a proportion of patients with low risk who received chemotherapy with little benefit. With the development of genomics, several gene sets have been demonstrated to be helpful in predicting of breast cancer prognosis and grading the patients' benefit from chemotherapy, thus avoid overtreatment. 21-gene Oncotype Dx was reported as one of them and has been demonstrated to be effective and accurate in various clinical studies. This paper summarizes researches on 21-gene Oncotype Dx in breast cancer.
