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 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 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.

Echinococcosis is a zoonotic parasitic disease caused by infection of Echinococcus granulosus and Echinococcus multilocularis in the human body,which may endanger the health and life of patients.Surgical treatment is presently the main method for the treatment of echinococcosis,with drug therapy as a subsidiary measure.The paper summarizes the advances in the treatment of echinococcosis.

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 assess the expression patterns of apoptosis-related genes in human pancreatic cancer cells (Patu-8988)induced by Kanglaite (KLT), a novel anti-cancer botanical product. Methods The apoptosis of Patu-8988 cells was determined by flow cytometry with Annexin V-FITC and propidium iodide staining. A human apoptosis microarray containing 96 cDNA fragments was used to detect gene expressions, and followed by Western blot analysis to confirm changes in expression of selected gene products. Results KLT induced apoptosis of Patu-8988 cells in a time-dependent manner. cDNA microarray analysis identified 5 down-regulated genes and 12 up-regulated genes (more than three fold) in the first 24 h as a consequence of treatment. Western blot performed for P53, Bcl-2, Bax and Caspase-3 were consistent with the microarray results. The enhanced activity of Caspases-3 was evidently verified by the cleavage of the 89?103 form of poly ADP-ribose polymerase. Conclusion KLT could alter the expression profile of apoptosis- related genes in human pancreatic Patu-8988 cancer cells, which provides valuable insight into the tentative signaling pathways mediating the outcome of KLT-induced apoptosis.

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 assess the diagnostic value of apparent diffusion coefficient (ADC) in the classification of solid nodules of brain parenchymal tuberculosis and response evaluation of patients.Methods Brain parenchymal lesions of 128 patients,with clinically and (or) pathologically confirmed brain parenchymal tuberculosis were analyzed retrospectively.Results Significant differences were observed in the average ADC values between enhanced areas and edematous areas of homogeneously enhancing and ring-enhancing lesions in all 128 patients before treatment(P<0.05).In 52 patients, the average ADC values of enhanced areas and edema areas in homogeneously enhancing and ring-enhancing lesions were significantly different before and after the treatment(P<0.05).Conclusion The ADC values in different areas of solid nodules of brain parenchymal tuberculosis are different, so can be used as a supplement to magnetic resonance imaging diagnosis and classification.After anti-tuberculosis treatment, the ADC values can be used as an observational indicator in follow-up.
