Objective To investigate the impact of different surgical methods and different doses of euthyrox on bone mineral density.Methods A sample of 40 patients received thyroid cancer operation (excised affected side leaf,aisthmus,most of offside and neck VI lymph node dissection)and 40 patients received nodular goiter operation (excised affected side leaf)were collected,the dose of euthyrox taken in was 85 .2μg in thyroid cancer patients and 36.2μg in nodular goiter patients daily,the bone mineral density 6 month and 1 year after operation was detected. Results There was no difference of BMD between the two group 6 month after operation (P>0.05),but BMD of the observation group was (0.64 ±0.28)g/m2,which was lower than that of control group (t=2.235,P=0.03).Com-pared with pre-operation,BMD of control group had no change and the observation group appeared drop 1 year after operation.Conclusion Patients received thyroid cancer taking in euthyrox may show BMD reduced,especial 1 year after operation,doctors should be on the alert and supplement calcium appropriately.

(0.05)).Conclusions PE is an effective form of treatment for recurrent FSGS by removing circulating factor,especially if initiated early.Failure to achieve remissions and maintain stable remission after the initial period of PE imply a poor outcome and glomeruli lesion been sclerosis.Therefore,PE should be performed as early as possible until completely remissions.

Objective:To investigate the effects of trimetazidine on cardiac systolic and diastolic function in patients with chronic congestive heart failure due to coronary artery disease.Methods:45 patients with chronic congestive heart failure due to coronary artery disease were divided into two groups,23 patients in trimetazidine group and 22 in placebo-control group.The echocardiogram indices of cardiac function of patients in two groups-SV,CO,CI,LVEF,VA,VE and VA/VE were measured before and after treatment.Results:The indexes SV,CO,CI and LVEF were significantly higher in trimetazidine group than those in control group(P0.05).Conclusion:Trimetazidine can improve systolic function of ischemic heart by improving the energy metabolism of ischemic heart.

Objective:To investigate the relationship among serum uric acid,C-reactive protein and the degree of carotid artery atherosclerosis in patients with essential hypetension.Methods:122 patients with essential hypertension were divided into intima-media thickness group(Ⅰ),plaque development group(Ⅱ) and vessel stenosis group(Ⅲ).Concentration of serum uric acid and C-reactive protein were measured in each patient and the relationship between serum uric acid and C-reactive protein was observed.Results:The concentrations of serum uric acid and C-reactive protein in group Ⅱ and Ⅲ were positively connected with pathologic changes of carotid artery atherosclerosis( P

A lot of children with congenital heart disease have an abnormal development of nervous system. A variety of biochemical and physical examination indices can be used to predict adverse outcome of neurodevelopment caused by congenital heart disease and they contribute to early intervention and improvement of neurodevelopmental disorders. In recent years, new progresses in the laboratory tests, neurological physiccal examination and perioperative management of the neurodevelopmental abnormalities caused by congenital heart disease have been made. The predictive factors of abnormal neurodevelopment caused by congenital heart disease were reviewed in this article.

Objectiye To explore the diagnostic and therapeutic methods of anastomotic leakage after low anterior resection of rectal cancer. Methods The clinical data of 16 cases with anastomotic leakage after sphincter saving operation which was performed through anterior resection for patients with lower rectal cancer were retrospectively analyzed. Results Among the 186 cases of low anterior resection of rectal cancer,16 cases occurred anastomotic leakage,incidence rate was 8.6% ;14 cases healed through local douche and drainage; 1 case healed by emergency operation and upper colostomy after bacterial peritonitis;only one elderly patient died for infectious shock. Conclusion Anastomotic leakage was the severe complication of low anterior resection,and timely correct treatment and doing well safety precautionary measures before operation could reduce the incidence rate of anastomotic leakage.

Image segmentation is a key step of image processing,and it is a hard work too. The experts of this field have tried to find a suitable algorithm for image segmentation for a long term,however,there is not a algorithm is generally accepted till now. J. Holland created genetic algorithm(abbreviation :GA) in 1973. This algorithm has been used in many fields successfully ,and has been introduced to image segmentation field by exports. The principles of image segmentation and algorithm are stated in this article. The author mainly expounded the application of GA in medical image segmentation field in recently years.

Objective To investigate the effects of limb ischemia-reperfusion injury(I-RI) on blood coagulation.Methods Eighteen patients scheduled for unilateral knee arthroscopy surgery under epidural anesthesia were treated with an inflatable tourniquet to ptoduce ischemia for (42 ± 6) min.Venous blood was taken before tourniquet inflation,at 30 min during ischemia,3 min and 30 min during reperfusion for measuring blood coagulation by thrombelastography(TEG).Results TEG showed the decreases in reaction time(R value) and coagulation time(K value),and the increases in alpha angle(α) and maximal amplitude(MA),which were all within the normal limits and had no significant differences among four time points of testing.Conclusion I-RI of the limbs has no significant effects on blood coagulation.

Ischemia-reperfusion injury can cause graft injury, and rapamycin, as an immunosuppressant commonly used clinically, show multiple effects on graft which after reperfusion. Here, we will review the role of rapamycin in renal ischemia-reperfusion injury.

Objective To investigate the mechanism of apoptosis induced by endoplasmic reticulum stress during sepsis.Methods Septic model of H9C2 cells was established by lipopolysaccharide (LPS).CHOP mRNA,mitochondrial membrane potential (MMP) and apoptosis were assessed by real-time PCR,flow cytometry respectively at LPS administration 24 h with or without salubrinal (inhibitor of endoplasmic reticulum stress).Results The expression of CHOP mRNA and apoptosis were upregulated,but MMP was decreased after LPS exposure 24 h compared with control group[2.40 ±0.30 vs 1.00 ±0,(16.58 ±2.71) ％ vs (3.85 ± 1.07) ％,1.07 ± 0.33 vs 2.62 ± 0.51,P ＜ 0.05).Compared with LPS group,salburinal pretreatment decreased LPS-induced upregulation of CHOP mRNA (1.60 ± 0.23 vs 2.40 ± 0.30,P ＜ 0.05),meanwhile,salburianl alleviated MMP(1.85 ± 0.31 vs 1.07 ± 0.33,P ＜ 0.05) and LPS-induced apoptosis [(6.05 ± 1.48) ％ vs (16.58 ± 2.71) ％,P ＜ 0.05].Conclusion Salubrinal plays a cytoprotective role against apoptosis induced by LPS through inhibition of CHOP mRNA,which leads to mitochondrial impairment.Endoplasmic reticulum stress may induce apoptosis via mitochondrial pathway in the septic model of H9C2 cardiomyocytes.
