ABSTRACT
Objective To investigate the therapeutic effect of oral administration of deuterium depleted water on gastroenteritis induced by 131I radiation in thyroid cancer treatment. Methods Fifty patients with papillary thyroid cancer treated with 131I in the Department of Nuclear Medicine of Changshu No.2 People’s Hospital from May 2022 to February 2023 were divided into control group and experimental group (25 patients in each group). Data were continuously collected throughout the study duration. The control group was orally administrated omeprazole enteric-coated capsules and purified water at 660 mL tid for 5 days. The experimental group received the same basic treatment as the control group except that deuterium depleted water was used instead of purified water. The incidence and alleviation of 131I radiation-induced gastroenteritis were observed and compared between the two groups using the Fisher’s exact test and Kaplan-Meier analysis. Results The number of gastroenteritis cases from day 1 to day 5 after 131I administration was 2 (8%), 5 (20%), 2 (8%), 1 (4%), and 0 (0%), respectively, in the experimental group, and 2 (8%), 8 (32%), 4 (16%), 3 (12%), and 1 (4%), respectively, in the control group. The incidence of gastroenteritis was significantly different between the two groups (χ2=4.064, P=0.044). After 5 days of treatment, the overall response rate of patients in the experimental group was 96%, which was significantly higher than 76% in the control group (χ2=9.105, P=0.025). Conclusion Oral administration of deuterium depleted water is effective in the relief of clinical symptoms of 131I radiation-induced gastroenteritis in thyroid cancer treatment. The clinical application of deuterium depleted water should be further investigated.
ABSTRACT
OBJECTIVE:To evaluate the short and long-term therapeutic effects of endoscopic variceal ligation(EVL) plus somatostatin on bleeding esophageal varices METHODS:64 patients with acute esophageal variceal bleeding due to portal hypertension underwent EVL,then the patients were divided into EVL group and EVL+somatostatin group RESULTS:The short-term hemostatic rates reached 93% in both groups There were significant differences in postoperative rebleeding rate and average interval of rebleeding between two groups(P
ABSTRACT
The authors discuss the technical problems in clinical evaluation of newly-developed Chinese medicines.For improvement of evaluation quality,this paper puts forward some suggestions for solving the common problems such as unitary intervention pattern,lack of corresponding treatment for the changed syndrome,subjectivity in standards of syndrome-differentiated diagnosis,ill-chosen medicine in control group,and mismanagement of medicine combination.
ABSTRACT
Objectiv To evaluate the usefulness of dot immuno-gold filtration assay(DIGFA) for the diagnosis of Paragonimus infection.Methods During 2003 to 2006,72 cases suspected of paragonimiasis in Zhejiang Province were examined with DIGFA for rapid detection of specific antibodies against Paragonimus(Pw-DIGFA).The diagnosis was primarily established with the presence of antibodies,experience of ingesting raw freshwater crabs or crayfishes and clinical presentations.The cases were treated with praziquantel and followed-up at 3 and/or 6 months post-treatment.Antibody level in patients(pre-and post-treatment) were detected in parallel and analyzed comparatively by Pw-DIGFA and ELISA.Results The result of detection by Pw-DIGFA was in agreement with that of ELISA.28 of 72 cases were antibody positive and 44 cases were negative.Among the 28 positives,26 cases had a history of eating raw freshwater crab or crayfishes and the other 2 cases drank freshwater from brook before.21 cases showed paragonimiasis-related clinical symptoms such as low-grade fever,cough,or changes in image examination,while the other 7 cases showed only eosinophilia in peripheral blood(15%-70%).The mean absorbance values(A450) of positive sera,negative sera and normal sera tested by ELISA were 1.7361,0.2973 and 0.2657 respectively.There was significant difference between the positive cases and the negative cases(t=12.047,P0.05).At 3 month post-treatment,serum antibody in 5 cases whose clinical symptoms and physical signs relieved or disappeared decreased 2-5 titers and that of one case who relapsed with new signs increased by one titer.In Pw-DIGFA,the dot color of 5 cured cases showed a little weaker than that of pre-treatment and the relapsed case displayed similar response.At 6 month post-treatment,7 sera of clinically cured cases showed significantly weaker response than that of pre-treatment.The antibodies of those sera dropped 3-6 titers.Conclusion Pw-DIGFA is of supplementary value for clinical diagnosis of paragonimiasis.Antibody detection by pre-and post-treatment using Pw-DIGFA shows potential for the evaluation of therapeutic effect.
