1.Clinical application of circulating microRNA in laboratory medicine
Chinese Journal of Laboratory Medicine 2011;34(10):865-870
microRNA(miR) in body fluids shows good stability and the change in its expression profile and level is associated with cancer and other diseases.Thus,circulating miR has been proposed to be an useful biomarker in diagnosis of the onset,prognosis and risk of diseases.Although great discoveries have been obtained on all aspects of miR,there are some shortcomings existing in the present studies,such as inconsistent specimens,diverse detection methods,lack of standardization on data analysis and other defects,resulting in poor reproducibility of data and inconsistent clinical conclusion,that make circulating miR difficult to be used in clinical laboratory testing.So lots of work is needed for us to implement,such as standardizing sample selection,improving detection reagents and methods,and normalizing test results before we can ultimately establish a fast,easy,low-cost detection of circulating miR in the clinical laboratory.
2.Pierre Robin sequence related genes
Chinese Journal of Tissue Engineering Research 2015;(24):3910-3915
BACKGROUND:Pierre Robin Sequence is a congenital malformation which is characterized by micrognathia, glossoptosis and respiratory tract obstruction with or without cleft palate. SOX9, KCNJ2, Ptprs and Ptprf are probably connected with Pierre Robin Sequence. OBJECTIVE:To review the recent progress in the researches on the related genes about Pierre Robin Sequence. METHODS:A computer-based online search of CNKI database and PubMed database was performed to retrieve the relevant articles published from January 1999 to September 2014 with the key words of“micrognathia, Pierre Robin Sequence, mutation, gene locus”in Chinese and English, respectively. Final y, 58 articles were included for review after deleting unrelated and repetitive ones. RESULTS AND CONCLUSION:SOX9, KCNJ2, Ptprs and Ptprf are probably connected with Pierre Robin Sequence. Recently, the research on the genes connected with Pierre Robin Sequence focuses on 17q23-24, and smal sample cases are commonly seen. But, further large sample test and case analysis, as wel as related animal models are needed to analyze the role of these genes in the pathogenesis of Pierre Robin sequence, as wel as consequently, we can analyze the etiology and pathogenesis of Pierre Robin sequence.

Journal of Medical Postgraduates 2004;0(02):-
Objective:This study was designed to measure the angles of the acetabular abduction when facing the different pelvic obliqueness angles.Methods:The angle of the acetabular abduction of 21 pelvis all 42 hip joints were measured with the manual devices when facing the 9 different pelvic obliqueness angles.Results:The pelvic obliqueness angle and abduction angle showed the positive linear correlation by the linear regress analysis.(r=0.999,P=0.000).The average abduction angle was 46.5?(43.8?-49.2?)when the obliqueness angle was 0?,as obliqueness angle of the pelvis increase to 10?,the abduction increase to 9.4?. Conclusion: The results provided reliable anatomical basis for total hip arthroplasty.

Methods The expressions of p27 protein and Ki 67 antigen in the adjacent tissues of carcinoma in 20 cases and 42 cases of clear cell carcinoma of kidney were detected by immunohistochemistry. Results The positive rates of p27 protein and Ki 67 antigen in clear cell carcinoma of kidney were significantly higher than those of the both in the adjacent tissues of carcinoma( P
5.Effect of psychological intervention on compliance of patients with hepatitis B treated with pegylated interferon alpha 2a
Chinese Journal of Biochemical Pharmaceutics 2017;37(8):224-225
Objective To investigate and analyze the influence of psychological intervention on the compliance of patients with hepatitis B treated with pegylated interferon alpha 2a. Methods 100 patients with hepatitis B treated in our hospital from April 2014 to October 2016 were selected and randomly divided into the control group and the experimental group, with 50 patients in each group. The experimental group and the control group patients were treated with pegylated interferon alpha 2a treatment, treatment time was 48 weeks, no other antiviral therapy. The control group was given routine care, and the experimental group was given psychological intervention on the basis of the control group. The treatment compliance of the two groups was compared and analyzed. Results After the corresponding treatment, the score of mental health in the experimental group was (9.94±2.01) points, and the score of mental health in the control group was (6.41±2.27) points. The scores of mental health in the control group were significantly lower than those in the experimental group, with statistical difference (P<0.05). Among the patients in the experimental group, three patients had poor compliance, 20 patients had good compliance, and 27 patients had good treatment compliance, and the compliance rate was 94%. Among the patients in the control group, 15 patients had poor compliance and the rate of compliance was 70%. The rate of good treatment compliance in the control group (70%) was significantly higher than that in the experimental group (94%), with statistical difference (P<0.05). Conclusion Ppsychological intervention can significantly improve the treatment compliance of pegylated interferon alpha 2a in patients with hepatitis B, and improve the quality of life of patients, so it has the clinical significance of further promotion and application.
6.Efficacy of different dose of Botulinum toxin A in treatment of patients with neurogenic detrusor overactivity
Journal of Regional Anatomy and Operative Surgery 2016;25(5):350-353
Objective To research the efficacy of different dose botulinum toxin A in the treatment of patients with neurogenic detrusor overactivity due to spinal cord injury or multiple sclerosis.Methods The datas of 43 patients with neurogenic detrusor overactivity caused by spinal cord injury or multiple sclerosis which accepted treatment in our hostipal were analyzed.And 38 patients were followed up for 12 weeks,of which 20 cases were treated with 200 U botulinum toxin A,and 18 cases received 100 U botulinum toxin A.The average age of 38 patients was 45.3 years old,and the ratio of famale was higher.The incontinence quality of life(I-QOL)changed from baselin after 6 weeks and 12 weeks was recorded.Resluts The final outcomes showed that the efficacy of botulinum toxin A with 200U was better than that with 100 U according to I-QOL score,and the difference was statistical significance(P <0.05).Conclusion The botulinum toxin A has positive effect on neurogenic detrusor overactivity,and the efficacy of 200 U injection is better than that of 100 U.

ObjectiveTo evaluate the killing effects of MMC,5-Fu and TAM on human breast cancer cell lines (MCF-7 and MDA-MB-435S). MethodsThe MTT method and median-effect principle were used. ResultsKilling effects of drugs were enhanced as drug concentration increased while they were used alone or in combination. The median-effect concentration of TAM in conjunction with MMC was 1.65?10 -5 mmol/L,and that of TAM in conjunction with 5-Fu was 0.032 6 mmol/L. MMC was synergetic with 5-Fu at high concentration(CI1). The ratios of drug concentration and the sequence of administration were not related with the killing effects. ConclusionsA combination of MMC, 5-Fu and TAM has an increased killing effect on MCF-7 cell lines and questionable enhanced effect on MDA-MB-435S cell lines.
