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.

Objective To study the expression of telomerase and its possible clinical significance in patients with condyloma acuminatum,bowenoid papulosis,Bowen's disease and vulvar squamous cell car- cinoma.Methods The human telomerase reverse transcriptase (hTERT) was detected by immunohisto- chemistry technique in all patients.Histopathological analysis was done in patients with bowenoid papulosis or Bowen's disease.Results There was a significant difference in the expression of hTERT among normal tissue,condyloma acuminatum and squamous carcinoma,and the expression rate increased successively from normal control to squamous carcinoma.In bowenoid papulosis,the expression of bTERT was significantly higher as compared to that in condyloma acuminatum,significantly lower as compared to that in squamous carcinoma,and was as the same as that in Bowen's disease.Histopathologically,the degree of cell atypia was significantly higher in Bowen's disease than that in bowenoid papulosis.Conclusions The expression of telomerase increases successively from normal skin,benign tumors to malignant carcinomas,which sug- gests that the expression of telomerase may play an important role in both cell proliferation and immortaliza- tion.

Objective To explore the difference of clinical features and laboratory indexs with different vasovagal responses in(head-up) tilt test(HUT) in children with vasovagal syncope(VVS).Methods Forty consecutive children diagnosed with VVS by HUT were analyzed.The vasovagal responses were divided into vasodepressor,cardioinhibitory and mixed patterns.The distribution and different clinical features and laboratory indexs of different response patterns in the VVS were studied.Results The most common vasovagal response was vasodepressor.There was no significant difference in their clinical features,including the motivation,presymptom,frequency and duration of syncope,baseline heart rate and blood pressure,and serum electrolytes among the children with different vasovagal respon-ses.Conclusion Vosodepressor response is the most common hemodynamic pattern in vasovagal syncope in children.

Objective: To explore the pathogenesis of oral lichen planus (OLP) by examining the expressions of hypoxia-inducible factor-la and RTP801 in OLP. Methods: To determine the expression levels of HIF-la and RTP801 in 24 OLP tissues and 12 normal oral mucosa tissues by real-time fluorescence quantitative PCR. Results; The expression of HIF-1α in OLP was higher than that in normal oral mucosa(P <0.05), while the expression of RTP801 in OLP was lower than that in normal oral mucosa( P <0.05). Conclusion; The abnormal expressions of HIF-la and RTP801 may play an important role in the pathogenesis of oral lichen planus. HIF-1α might be a potential molecular target for the treatment of OLP.

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

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.
