International Journal of Laboratory Medicine 2014;(15):2065-2066
Objective To comparatively analyze the results of the PT derivative method and the Clauss method for detecting fi-brinogen(Fib) by the automated coagulation analyzer and to explore their accuracy and clinical value .Methods Fib was detected in 156 blood samples selected from the patients in this hospital from March to May 2013 ,25 normal control samples and 13 positive samples of D-dimer (DD) by the TP derivative method and the Clauss method .Results The Clauss method and the PT derivative method by Sysmex CA-1500 coagulation analyzer had good repetitive rate in measuring Fib for 25 times ;when Fib<1 .0 g/L ,the results detected by these two methods had statistically significant difference (P<0 .05);when Fib in the range of 1 .0 -2 .0 g/L , 2 .1-3 .0 g/L ,3 .1-4 .0 g/L ,the detection results had no statistically significant difference between the two methods (P>0 .05);when Fib in the range of 4 .1 -5 .0 g/L ,the detection results had statistically significant difference (P<0 .05);when Fib>5 .0 g/L ,the detection results had statistically significant difference (P<0 .05);in 13 DD positive samples ,the detection results of the PT derivative method were significantly higher than those of the Clauss method with statistically significant difference (t=8 .530 , P<0 .05) .Conclusion The difference exists between the PT derivative method and the Clauss method for detecting Fib ,but the ac-curacy of the Clauss method is higher than its specificity ,the Clauss method should be the first choice for the clinical determination of plasma Fib .
2.Establishment of chromatin immunoprecipitation assay to analyze transcriptional regulation of gene expression
Chinese Journal of Laboratory Medicine 2001;0(05):-
Objective To establish a Chromatin immunoprecipitation assay to analyze transcriptional regulation of gene expression in hepatocytes. Methods The PEPCK gene was used as a target gene, HPRT, MBP and IgG were used as internal reference, the chromatin immunoprecipitation and PCR were performed with antibody specific for CREB to verify bindings of transcription factor CREB to the PEPCK promoter under various metabolic conditions. Results Transcription factor CREB occupies its target sites in the PEPCK promoter and this binding is increased by 4-fold during fasting in the anti-CREB antibody immunoprecipitated DNA fragments. Conclusion The results confirm that CREB binds to the PEPCK promoter and is involved in transcriptional regulation of PEPCK gene in hepatocytes.
3.Clinical analysis on complicated arrhythmia after 104 cases lung resection
Journal of Chongqing Medical University 2003;0(05):-
Objective:To analyze the reasons of complicated arrhythmia after resection of lung. Methods:The relation of arrhythmia with age, operation mode,preoperative lung function and postoperative blood gas of 562 cases of lung resection were analyzed. Results:There were 104 of 562 cases (18.5%) complicated with arrhythmia postoperatively. 38.77% of them were older than 70 years. 27.72% had operation of pneumonectomy.The parameters of FEV 1,MVV,FVC lower than 50% were 67.24%,46.53% and 67.93% respectively.Postoperative blood gas analysis of the 23 cases showed that Po 2 was lower than 60 mmHg,Pco 2 was higher than 45 mmHg,So 2 was lower than 96%.21 of them developed postoperative arrhythmia.After tracheotomy and immediately correcting anoxia,all the 21 patients recovered from arrhythmia within 3 days.4 patients died in this group(3.84%).Conclusion:Pneumonectomy,in patients older than 70,results in the parameters of FEV 1,MVV and FVC lower than 50%.Significant anoxia is the cause of arrhythmia.

Journal of Chongqing Medical University 1987;0(01):-
Objective:To discuss the method of Video Assisted Thoracoscopy(VATS) in diagnosis and treatment of small peripheral lung neoplasm.Methods:A wedge-shaped excision with VATS had been performed on 20 patients with small peripheral lung neoplasm.The sample had been sent to pathology during surgery.Lobectomy was done with the malignant tumor.Results:14 cases(70%) were malignant in stage IA ,6 cases were benign.The mean follow-up time postoperatively was 24 months(12~36months),there was no relapse case.Conclusion:For those patients,the diameter of neoplasm is smaller than 15mm,and antibiotic treatment is ineffective for 2~3 weeks,VATS can be available for diagnosis and treatment.

China Pharmacy 2001;0(07):-
OBJECTIVE: To observe the effects of long-term administration of pioglitazone at different doses on the expression of glucose transporter-4(GLUT-4) of cardiac muscle tissue in rats and to discuss the possible mechanisms.METHODS: A total of 40 Wistar rats were enrolled,of which,10 were randomly assigned to normal control group(NC),and the other 30 were injected intraperitoneally with streptozotocin to establish diabetes mellitus(DM) rat model.After successful modeling,the rats were assigned to DM model group(DM,normal saline),high and low dose pioglitazone group(HP,LP;0.75,0.25 mg?kg-1?d-1).The NC groups received normal saline for 12 weeks.Blood glucose(BG) level before grouping(baseline level) and prior to death was determined by tail-cutting method.GLUT-4 level in cardiac muscle tissue and both protein and mRNA expression of AMPK? were determined by RT-PCR and western blot,respectively.RESULTS: As compared with NC group,the BG level in DM group was significantly increased but the expression of GLUT-4 and AMPK? decreased significantly(P

Chinese Journal of Medical Education Research 2013;(10):1043-1046
Objective To explore the value of evidence-based medicine (EBM)induced con-cept mapping in the teaching rounds in the department of cardiology. Methods Totally 25 medical students were taught to use EBM based concept mapping in preparing the medical teaching rounds during their rotations in the department of cardiology. Training of ward round ability was conducted by familiarizing with the producing method of concept map,selecting cases,posing questions,looking for literatures and discussing the concept map. Then assessment of this method was investigated and compared with that of the traditional teaching rounds method in other departments. t test was used and P≤0.05 was considered statistically significant. Results Compared with traditional method,EBM based concept mapping method showed advantages in cultivating medical students' critical thinking ((4.58±0.89)vs. (4.01±1.02)),creativity ((4.38±0.92)vs. (2.45±0.88))and integrated clinical thinking ((4.08±0.67)vs. (3.59±0.49)),self-study ability ((4.81±0.88)vs. (3.01±1.18))and literature search ability(P<0.05). Conclusions EBM based concept mapping can be a useful teaching ward round tool,which could efficiently improve teaching round quality and assist medical students in overall clinical skills.

10."Discussion on ""Fire Stagnation Requiring Dissipation"""
Journal of Zhejiang Chinese Medical University 2015;(10):727-729
Objective]To explore the basic connotation of “fire stagnation requiring dissipation”and analyse ancient physicians' discussion about the fever, in order to expand its application in the clinical treatment.[Method] Using the method of conceptual thinking to explain the etiology and pathology of“fire stagnation”,the specific connotation of“fire stagnation requiring dissipation”,collecting ancient physicians' exposition on“fire stagnation requiring dissipation”,and listing the relevant prescriptions in order to deepen the thinking.[Result] Fire stagnation produces nothing more than exogenous ,internal injuries,the mechanism is in the human body, the anger's ascending-descending and coming in-going out is out of balance by some factors ,the anger stagnates and can't get out. Neijing first recorded“fire stagnation requiring dissipation”,that is treating the fire stagnation disease needs making the gas opening,lifting,entry becomes coordinate,finally the body goes back to health. In the Shang Han Lun, Zhang Zhongjing expounded the meanings and mechanism of“fire stagnation requiring dissipation”perfectly. Since Jin and Yuan Dynasties, ancient physicians have come up with several prescriptions and have promoted the development of the doctrine.[Conclusion] Since the Neijing proposed the theory of“fire stagnation requiring dissipation”,physicians' understanding of fire stagnation syndrome has been gradually deepening,and provided a broader ideas for clinical treatment.In recent years,the theory of“fire stagnation requiring dissipation”is widely used in various kinds of diseases,its academic value is worth summarizing,inheritance,extension.
