Chinese Journal of Organ Transplantation 2012;33(8):466-469
ObjectiveTo explore the possible mechanism that Gadd45a and Egr-1together participate in the DNA damage repair,by analyzing the influence of hepatic ischemia-reperfusion injury (IRI) on the rnRNA and protein expression of hepatic cell cycle-related genes.Method Methods Forty-two SD rats were divided into normal control group,ischemia 30 min group and reperfusion 30 min,1h,2 h,3 h and 24 h groups.The hepatic specimens of rats at the corresponding time points after success of modeling were obtained. Chip experiment was used to screen out the key genes Gadd45a,Egr-1and GAPDH for target genes.We used Northern blot and RT-PCR to confirm the chip's results. The expression of related proteins was detected by using immunofluorescence and immunohistochemistry.Results Northern blot detection results showed that the RT-PCR products and the target genes for testing were concordant.The expression spectral chip signal and RT-PCR detection revealed that the expression of target genes had a 4-fold increase at early reperfusion period (1h) (up-regulation of Egr-1,Gadd45a and HSP70-1a by 9.39,8.28 and10.8 respectively.At the later stage of reperfusion (24 h),the expression of Egr-1,Gadd45a and Hspala was reduced to the normal levels, and the chip screening results were consistent with the RT-PCR test results.Fluorescence immunohistochemistry demonstrated that in the reperfusion1h and 2 h groups,the expression of Egr-1in nuclei of liver cells was positive. Immunohistochemistry indicated that the Gadd45 expression in the nucleus and cytoplasm was gradually increased with increasing reperfusion time.ConclusionGadd45a and Egr-1are the key genes of the nuclear factor (NF)-kB regulatory pathways,and involved in the regulation of cell cycle arrest at G2/M phase and repair of damaged DNA in rat hepatic IRI.

Chinese Journal of Current Advances in General Surgery 1999;0(04):-
Objective:To evaluate the effect of Indomethacin suppositories on albumin concentration and insulin resistance of post-operation patients with serious intra-abdominal infection.Methods:38 post-operation patients with serious intra-abdominal infection were divided into two groups randomly.One as treatment group(n=19)and the other as control group(n=19).Albumin,blood glucose,fasting insulin concentration were measured At 72 hours after the operation and 144 hours.Insulin resistance index was calculated using the homeostasis model assessment(HOMA).Finally,the results of two groups were analyzed.Results:The albumin concentration of Indomethacin group at 72 hours was significantly higher than that after 72 hours,Insulin resistance of 144 hours was lower than the control group(P0.05).Conclusion:Postoperative abdominal infection using indomethacin suppository can significantly reduce insulin resistance,and significantly reduced the decomposition of albumin.
4.Morphological study on skeletal satellite cell transplantation applied in therapy of myocardial infarction
Basic & Clinical Medicine 2006;0(02):-
Objective To find the features of cryo-injured infarcted model and the therapeutic effects of skeletal satellites cells(SCs) on myocardial infarction(MI).Methods SCs were implanted into the center of cryo-injured myocardium.Immunohistochemistry,confocal immunofluorescence double-labelling staining and transmission electron microscopy were used to study the state of SCs.Results After cryo-injured frontal wall of the left ventricle(LV) for approximately(15 s) by aluminium rod with(5 mm) in diameter,it made 43% weight of LV ischemia and 17% weight of LV infarcted.At 2nd week,injured area occured as transmural infarct.After transplantation,the implanted cells survived in large numbers.The transplanted cells proliferated remarkably at early phase and differentiated into many multinuclear myotubes after 2 weeks.Some of them developed into muscle fibers with better sarcomeres,but the gap junction was not formed between implanted cells and cardiac myocytes.Conclusions Cryo-injured infarcted model is a proper model to study myocardial infarction.Skelatal satellite cell transplantation will repair morphological structure partly of myocardial infarction area.
5.Application of elastic stable intramedullary nailing fixation for treatment of long bone fractures in children
Chinese Journal of Applied Clinical Pediatrics 2015;30(23):1761-1765
Elastic stable intramedullary nailing (ESIN) is a well-accepted fixation method of long bone fractures in children.The advantages of ESIN include primary bone union with avoidance of growth plate injury and minimum invasive surgery.The good results of ESIN are obtained when surgeons have a good knowledge of the principle of the correction of the fracture and its stability, especially in the understanding of the unique pathophysiology characteristics of pediatric fractures.This review discussed the biomechanical mechanisms of ESIN, and the principles,indications and contraindications of ESIN in the treatment of pediatric long bone fractures.The article also comprehensively introduced the application of ESIN in femur,tibia,fibula,humerus, ulna, radius,clavicle and metacarpal bone fractures.The technique details of nailing, preoperative planning, positioning of the patient, sizing of the nail, entry points for the nail, reduction maneuvers for safe passage of nails through the fracture site, and postoperative management were also introduced in this review.

9.Efficacy of differential antihypertensive treatment strategies at early stage in the elderly with acute cerebral hemorrhage
Chinese Journal of Geriatrics 2012;31(4):302-304
Objective To observe the the therapcutic efficacy of differential antihypertensive treatments on the elderly acute cerebral hemorrhage with different amounts of bleeding. Methods 86 elderly patients with acute cerebral hemorrhage combined by hypertension were randomly divided into two groups:active antihypertensive group and regular antihypertensive group (n=43 for each group),among which 62 cases aged (68.9±5.3) years were in hemorrhage of small amount (volume <30 ml),24 cases aged (70.8 ± 5.7) years in large amount hemorrhage (volume ≥30 ml).The patients in active antihypertcnsive group received intravenous antihypertensive drugs within 1 hour of treatment in the following 7 d to reach systolic pressure 140-160 mm Hg.In contrast,in the control group the patients' systolic pressure reached 180-200 mm Hg at early stage.The hematoma volume was measured by CT before treatment and at 3 d and 7 d after treatment.NIH stroke scale (NIHSS)was used before treatment and 7 d and 28 d after treatment Results In the patients with small amount of bleeding,NIHSS scores and the total efficacy rate at 28 d after treatment and hematoma size at 3 d after treatment were better in active antihypertensive group than in regular antihypertensive group [(4.8±2.7) scores,86.67% aud (2.4±0.6) ml vs.(7.6±3.9) scores,53.13% and (8.1±3.1) ml,all P<0.01]. However,for the patients with large amount of bleeding,there were no statistical differences in the above indexes between the two differential strategies (all P>0.05).Conclusions Active antihypertensive therapy may inhibit early hematoma volume,improve prognosis and enhance clinical efficacy for the patients with small bleeding,but no clinical significance for the patients with large amount of bleeding.
