ObjectiveTo study the clinical value of minimally invasive treatment of the doppler-guided hemorrhoid artery ligation with lauromacrogal sclerosis injection in treatment of hemorrhoids.MethodsA retrospective analysis was made on treatment of 32 cases with hemorrhoids using doppler-guided hemorrhoid artery ligation combined with lauromacrogal sclerosis injection.ResultsAccording to the branch of the Chinese Medical Association by the Surgery the clinical diagnosis and Treatment Guidelines of Hemorrhoids (draft),the Ⅰ degree hemorrhoid was found in 1 case,Ⅱ degree hemorrhoids in 18 cases,Ⅲ degree hemorrhoids in 13 cases.Recovery was found in 32 cases.The longest follow-up time was 30 weeks.No relapse was found. ConclusionsDoppler-guided hemorrhoid artery ligation combined with lauromacrogal case sclerosis injection is a low aggressive minimally invasive method to treat hemorrhoid and has small trauma,definite effect,less pain,fewer complications,and short course and other advantages,but the longterm outcome needs further observation.

Free fatty acids generated from the metabolites of fat have been demonstrated to stimulate the neutrophils to produce reactive oxygen species ( ROS) such as hydrogen peroxide and chlorous peroxide .It has shown that free fatty acid is closely related with myocardial, vascular endothelium, liver, lung and other tissue damage.The mechanism of erythrocyte injury is oxidation of mem-brane polyunsaturated fatty acids and cytosolic hemoglobin by ROS .High levels of free fatty acids can increase the formation of active reaction molecular ROS , thus initiating the oxidative stress reaction .Active molecules can oxalate and damage the DNA , protein, lipid and other molecules of RBC .It has revealed the relationship between free fatty acids and erythrocytes injury , which provided a new di-rection in the research of oxidative anemia .This article reviews the advances in the research of this subject in recent years .

Objective To evaluate the relationship of intraerythrocytic calcium(Ca~(2+)),serum cardiac troponin I(cTnI) and contractile and diastolic dysfunction in infants with pneumonia complicated with heart failure(HF),and discuss the role of Ca~(2+) and cTnI.(Met)-hods One hundred and thirty-three infants with pneumonia complicated with HF and 30 healthy children were studied.Intraerythrocytic calcium,serum cTnI and ejection fraction(EF),fractional shortening(FS) and E/A were measured by color Doppler ultrasoundraphy.Results Intraerythrocytic calcium,serum cTnI and EF,FS and E/A in two groups had difference.With the disease deteriorating,the values of Ca~(2+) and cTnI increased,and EF,FS,E/A decreased gradually.There were negative relations between Ca~(2+),cTnI and EF,FS,E/A.Conclusions Ca~(2+),cTnI are concerned with the development of HF.In clinical experiments,the contractile function and diastolic function of heart can be judged by the levels of intraerythrocytic calcium and serum cTnI.

Objective To probe the effect of c-fos gene on the pentyleneterazol-induced hippocampal neurons apoptosis.Methods Using immunohistochemistry,TUNEL and flow cytometry(FCM),we detected the Fos expression and the apoptosis of hippocampal neurons;we injected c-fos antisense into ventrile before epilepsy and detected as up.Results Epilepsy can induce the expression of Fos in the hippocampus and peaking at 1 h(P

Objective To explore the relationship of human cytomegalovirus(HCMV) infection and infantal epilepsy.Methods Fluorescence quantitative polymerase chain reaction was employed to detect the urine HCMV-DNA in 20 healthy children and 52 infants with epilepsy,and the changes in head CT scanning and brainstem auditory evoked potential were determined in HCMV positive and negative epilepsy infants.Results Positive HCMV-DNA was found in 31(59.62%)infants with epilepsy and 6(30%)healthy infants,there was significant difference between two groups(P

The value of prophylactic cranial irradiation (PCI) for small cell lung cancer (SCLC) remains controversial. From Nov.1987 to Jan. 1993, thirty-one patients with small cell lung cancer received PCI. PCI was given for complete remission SCLC patients after chemotherapy and chest radiotherapy. The total dose of PCI was 40Gy in 26 cases, 30～

BACKGROUND:Hidden blood loss leads to severe anemia after orthopedic joint arthroplasty.Blood transfusion is needed.Use of tranexamic acid can significantly decrease perioperative blood loss,reduce blood transfusion rate,however,mechanism of action of tranexamic acid on hidden blood loss and its relevance are not clear.OBJECTIVE:By establishing the rabbit models of total knee prosthesis,this study was designed to observe thevariation of early preoperative blood loss with tranexamic acid,and to study the effects of tranexamic acid on hidden blood loss and its influence on deep venous thrombosis of lower limb.METHODS: We designed the rabbit knee prosthesis ourselves.A total of 20 adult New Zealand rabbits were randomly divided into two groups,each group with 10 rabbits.Knee arthroplasty on the same side was performed.Experimental group received intravenous injection of 0.5 g 100 mL tranexamic acid at 15 minutes before replacement.Control group was given 100 mL sodium chloride at the same time.Blood was colected from al animals through ear vein at 1 day before replacement,3,6,24,48,72 hours and 7 days after replacement.Blood routine examination and blood coagulation function test were conducted.The content of plasma D-Dimer was determined.Simultaneously,the operation time and intraoperative bleeding amount were recorded.After replacement,lower limb venous ultrasonography was performed.RESULTS AND CONCLUSION: No significant difference in body weight,hemoglobin,hematocrit,and D-Dimer levels was detected between the two groups before replacement (P＞0.05).Significant differences in operation time and intraoperative dominant blood loss were detectable between the two groups (P＜0.05).Significant differences in hemoglobin and hematocrit were detected at 24 hours after replacement (P＜ 0.05),and these were better in the experimental group than in the control group.No significant difference in D-Dimer was observed between the two groups after replacement (P＞ 0.05).Operation time and intraoperative dominant blood loss were significantly associated with hemoglobin and hematocrit at 24 hours after replacement (P＜0.05).The changes in hemoglobin and hematocrit at 72 hours and 7 days after replacement were not apparently correlated with intraoperative D-Dimer changes.Obvious thrombus was not seen by lower limb venous ultrasonography after replacement.These results indicated that the use of tranexamic acid before total knee arthroplasty apparently reduced the intraoperative dominant blood loss,shortened operation time,and noticeably decreased hidden blood loss at 1 day after replacement,which was caused by the increased fibrinolysis with surgical stress,and did not apparently impact other hidden blood loss induced by other mechanism.Simultaneously,tranexamic acid is safe and reliable,and does not increase the risk of perioperative thrombus.

Objective To explore the expression of myelin transcription factor 1 (MyT1) and its significance in the brain of epileptic rats induced by lithium chloride-pilocarpine. Methods Models of epilepsy of SD rats were established by intraperitoneal injection with lithium chloride and pilocarpine. MyT1-positive cells in the cortex and hippocampal field CA 1 of epileptic rats were determined by immunofluorescence histochemistry.Results Compared with the control group, the number of MyT1-positive cells within the cortex and hippocampal field CA 1 of epileptic rats decreased significantly at 1 day after seizure ( P
