Progress in Biochemistry and Biophysics 2006;0(07):-
Chitinases are ubiquitous chitin-fragmenting hydrolases, however until a few years ago that chitinase like proteins have been found in mammalian. A silica-induced bronchoalveolar lavage protein (iSBLP58) with fibroblast growth promoting activity in silicotic rat, which had high sequence homology with members of the mammalian chitinase protein family has been previously purified and characterized. Bioinformatics analysis showed that several human EST clones from pooled colon, kidney or stomach matched the rat protein sequence. Thereafter clone from human kidney RNA samples with several pairs of primers was managed and a set of sequences was obtained, whose cDNA and amino acid sequences have high similarity with each other and several human chitinases in GenBank. Comparison with human genome sequence suggests that these molecules may be from variant transcripts of same a Pre-mRNA. Here the characterization of these sequences is reported.
2.Complications of chronic kidney disease:current management and challenge
Chinese Journal of Practical Internal Medicine 2001;0(02):-
Chronic kidney disease(CKD)is increasingly recognized as a global public health problem.Uncontrolled complications of CKD,especially cardiovascular diseases,contribute greatly to the premature death and unfavorable prognosis.Recent evidence shows that CKD complications may occur earlier than previously thought.CKD complications deserve early detection and active treatment.Periodical follow-up and regular check should be done to adjust the therapeutic condition.Clinical practice guideline or recommendation based on evidence-based medicine is essential for management of CKD complications.Personalized treatment should be considered to improve survival and quality of life,and to make patient return to society.
3.A retrospective study of posterior lumbar disc herniation
Chongqing Medicine 2017;46(15):2083-2084
Objective To study the effect of different therapies for posterior lumbar disc herniation.Methods A total of 8 000 patients with lumbar disc posterior surgery were enrolled in this research at our hospital.The technical points of the patients in different times were analysed.The results of the operation were observed.Results From January 1980 to December 1990,patients underwent laminectomy.From January 1991 to December 2000,patients were treated with laminectomy and semi-lamina.From January 2001 to December 2016,the open window accounted for 86.0%,expanding the window or semi-lamina accounted for 11.0%,and the whole laminar plate only accounted for 3.0%.After 2000,the accuracy of the diagnosis was 98.0%,the excellent rate of operation was 99.8%,the average operation time was(80±15)min,and the blood loss was(100±20)mL.Among them,the rate of I/A healing was 99.8%,dural tear rate was 4.0%,nerve root injury rate was 0.5%,and cerebrospinal fluid leakage rate was 0.9%.The incidence of complications in the cases after 2000 was significantly lower.Conclusion By summarizing the operation technique of posterior lumbar disc herniation,the operation error can be avoided and the incidence of complications of surgical injury can be reduced.
4.Laparoscopic cholecystectomy for acute cholecystitis: A clinical analysis of 79 cases
Chinese Journal of Minimally Invasive Surgery 2001;0(01):-
Objective To summarize the clinical experience of laparoscopic cholecystectomy (LC) for acute cholecystitis. Methods Clinical records of 79 cases of acute cholecystitis treated by LC from September 2002 to August 2003 were respectively reviewed. Results Intraoperative cholangiography (IOC) was successfully conducted in 75 cases, 6 of which were found common bile duct stones. Of the 6 cases, 4 underwent LC combined with intraoperative endoscopic sphincterotomy and 2 underwent a conversion to open choledochotomy with T-tube drainage. The rest of 73 cases were diagnosed as simple gallbladder stones: LC was successfully accomplished in 70 cases and a conversion to open surgery was required in 3 cases because of serious inflammatory adhesion. In the study no severe complications occurred. Conclusions LC can be performed safely in the majority of cases of acute cholecystitis.
5.Molecular biological markers on diagnosis of early gastric cancer
Chinese Journal of Disease Control & Prevention 2001;5(2):139-141
Gastric cancer(GC) is deeply threatening the health of our people, the mortality rate of GC is the second death cause of carcinoma i n our country. Since the lack of special clinical symptom at the early state of GC, detecting GC at the molecular biological level is expected to diagnose early gastric cancer. This article discusses some markers such as PCNA, p53, telomera se, ras protein and so on to assess the possibility of diagnosing the early gas tric cancer with these molecular biological markers. According to analyzing rela ted papers published, PCNA and p53 were found to be the molecular biological mar kers which should be firstly taken into account in diagnosing gastric cancer. Bo th of them can be easily detected by using immunohistochemical method. Telomeras e is also a good marker, but because of its difficult technology and high cost, it is not so practicable as the former two as the diagnostic marker of early gas tric cancer. Besides, ras potein can also be taken into account as the early det ecting auxiliary marker for GC.
6.Use of retrograde intrameduilary interlocking nail for the treatment of distal femoral fracture with analysis 52 cases
Chinese Journal of Primary Medicine and Pharmacy 2008;15(7):1121-1122
Objective To summarize the clinical effects of retrograde intramedullary nail in treating distal femora| fracture. Methods Retrospectively analysed 52 cases of intereondyiar and supracondylar fracture of femur treated with retrograde intrameduUary nail. Results All cases were followed up for 6 to 24 months. All fracture were union except 2 reoperations cases had delay union. Conclusion Retrograde intrameduUary nail has supreme biological stability and allowed early exercise. It also can shorten operation time, reduce damage of periosteum and reduce delay union rate.
7.The study of the influence of self-management on health care behavior among patients with hypertension in Pingshan community
Chinese Journal of Health Management 2008;2(3):153-155
Objective To observe the influence of self-management on health care behavior through health education for patients with hypertension after a self-management model was brought to the communities. Methods There are 252 cases chosen randomly from 546 hypertensive patients in 19 communities to participate in the standard management of hypertension in communities voluntarily. They improve their self-management skills through attending lectures, the guidance of healthy lifestyle and self-management manuals. A scientific self-management methods was established and the support of the society and family was improved. The self-control method was used to analyze this study. Results There are significantly differents (P<0.05 ) in basic health knowledge understanding, self-management skills, and blood pressure control after health education compared with before. Conclusions Patients with health education can improve the self-management level. There are obvious effects on changing the bad lifestyle,improving blood pressure control rate, and decreasing the complication of patients with hypertension.
8.Progress on the association between respiratory viral infections during early-life and asthma attack in later childhood
International Journal of Pediatrics 2010;37(6):585-587
Respiratory viral infections are the most common cause of infantile wheezing, as well as one of the major inducents of acute exacebarbations of chronic childhood asthma. Recent studies focus on the mechanism of virus-induced airway inflammatory response which is still not completely clear. Many new pathophysiologic mechanisms such as epigenetics are advanced to explain the association between viral respiratory infections and asthma attack. In the present reports, recent data on the role of early-life viral infections in the development and progression of childhood asthma are reviewed.
9.Application of population pharmacokinetics in the rational usage of immunosuppressive drugs
Chinese Pharmacological Bulletin 2010;26(2):159-163
Population pharmacokinetics(PPK),which is based on the principle of statistics,can be used to estimate various inter- and intra-individual factors which affect pharmacokinetics.By using Bayesian estimator,PPK can predict individual pharmacokinetic parameters accurately.PPK is widely used in the immunosuppressive therapy with cyclosporine,tacrolimus,mycophenolic acid and sirolimus.
