RESUMO
ObjectiveTo investigate the efficacy， safety， and cost-effectiveness of endoscopic ultrasound （EUS）-guided coil placement combined with tissue adhesive injection in the treatment of gastric varices with spontaneous shunt. MethodsA retrospective analysis was performed for the patients with acute gastric variceal bleeding and spontaneous portosystemic shunt who were hospitalized and received balloon-occluded retrograde transvenous obliteration （BRTO） combined with endoscopic tissue adhesive injection or EUS-guided coil placement combined with tissue adhesive injection in Xiangyang Central Hospital from March 2019 to September 2022. The two surgical procedures were compared in terms of efficacy （technical success rate， 5-day rebleeding rate， 1-year rebleeding rate， and time to rebleeding）， safety （the incidence rate of ectopic embolism， the amount of tissue adhesive used， and the amount of lauromacrogol used）， and cost-effectiveness （hospital costs and length of hospital stay）. The t-test was used for comparison of normally distributed continuous data between two groups， and the Mann-Whitney U test was used for comparison of non-normally distributed continuous data between two groups. The Kaplan-Meier method was used to estimate the rebleeding. The chi-square test was used for comparison of categorical data between two groups. ResultsA total of 25 patients received successful EUS-guided coil placement and tissue adhesive injection， with a technical success rate of 100%， a median amount of 2.5 mL tissue adhesive used， a median amount of 11.0 mL lauromacrogol used， a mean length of hospital stay of 14.88±3.21 days， a mean hospital cost of 32 660.00±4 602.07 yuan， and a 5-day rebleeding rate of 0%； among these patients， 2 were lost to follow-up， and 23 patients with complete follow-up data had an incidence rate of ectopic embolism of 0% and a median time to rebleeding of 689 days. A total of 14 patients underwent modified BRTO combined with endoscopic tissue adhesive injection， with a technical success rate of 100%； a median amount of 5.0 mL tissue adhesive used during surgery， which was significantly higher than that used in EUS （U=39.000， P<0.001）； a median amount of 10.5 mL lauromacrogol used during surgery； a mean length of hospital stay of 15.38±4.94 days； a mean hospital cost of 57 583.47±18 955.40 yuan， which was significantly higher than that used in EUS （t=-6.310， P<0.001）； a 5-day rebleeding rate of 0%. No patient was lost to follow-up， and all 14 patients had an incidence rate of ectopic embolism of 0% and a median time to rebleeding of 244.50 days， with no significant difference between the two groups （χ2=1.448， P=0.229）. ConclusionEUS-guided coil placement combined with tissue adhesive injection is a relatively safe and effective technique for the treatment of gastric variceal bleeding and has a high technical success rate， a low incidence rate of serious adverse events， and similar efficacy to BRTO， with higher safety and cost-effectiveness.
RESUMO
Objective To evaluate the effects of compound glycyrrhizin on the percentage of Th17 cells and expression of interleukin(IL)-17A in peripheral blood of patients with psoriasis vulgaris, and to explore their relationship with therapeutic effects. Methods A total of 30 patients with mild to moderate progressive psoriasis vulgaris were randomly and equally divided into two groups:group 1 treated with compound glycyrrhizin injection, antihistamines and topical drugs, group 2 treated with antihistamines and topical drugs. Twelve healthy human subjects served as the control group. Blood samples were collected from the patients 1 day before start of treatment and after 3 weeks of treatment, and from the control group. Flow cytometry and enzyme-linked immunosorbent assay (ELISA)were performed to determine the percentage of Th17 cells and expression level of IL-17A respectively in the peripheral blood samples. Results Before the treatment, the percentage of Th17 cells and expression level of IL-17A were both significantly higher in the two patient groups than in the control group (all P0.05). Furthermore, both Th17 cell percentage and IL-17A expression were significantly different between the two patient groups after the treatment (both P< 0.05). Conclusion Compound glycyrrhizin may treat psoriasis vulgaris by regulating Th17 cell percentage and IL-17A expression in peripheral blood.
RESUMO
Student evaluation is an important part of the teaching process.The Children's Hos-pital of Chongqing Medical University focused on the characteristics of individual child's growth and overall development according to the own condition and integrated formative assessment and summa-tive evaluation in the classroom teaching and clinical internship process. All the measures mentioned above not only help promote students' learning interests,master of knowledge and clinical skills but also exert positive effect on the improvement of teaching level.
RESUMO
ObjectiveEvidence-based medicine was used to make an individualized treatment plan for rare solitary splenic metastasis of an ovarian carcinoma in a female patient. MethodsAfter clinical problems were discovered, evidence was collected from the Cochrane Library, PubMed, EMBASE, ScienceDirect, CNKI and Wanfang databases according to our predefined search strategy. The search was done until October, 2009. The validity of the evidence was assessed. The evidence, combined with the doctor experience and the patient value, was applied to the patient. ResultsA total of 15 English literature and 11 Chinese literature were identified. A rational treatment plan was made upon a critical evaluation of the data. There were 5 review articles in PubMed, EMBASE and ScienceDirect databases and no RCT in the Cochrane Library. And there was one retrospective cohort study inCNKI and Wanfang databases. The others were all case reports. After 20 month follow-up, the treatment protocol was proven correct. Conclusion The patient has rare disease, and the evidence intension for the evidence-based medicine was low. It can not present the efficacy of the evidence-based medicine treatment sufficiently, though it could provide some suggestion for rare disease which was lack of large RCT for evidence-based Methods .
RESUMO
Objective To study the academic level of randomized control trials(RCTs)published from 2004 to 2009 in Chinese Journal of Hepatobiliary Surgery.Methods Published work about RCTs in 72 issues of Chinese Journal of Hepatobiliary Surgery was searched by finding relevant articles published during 2004-2009.Correlated indexes including literature received time, literature publishing time, the total number of citations, number of citations in Chinese, number of citations in English, research funding situations, the number of authors, article affiliations in all RCTs, together with single(or multiple)center study situation, positive conclusions, the starting time, the end time,and number of patients recruited in clinical RCTs were extracted for aggregate analysis.Results During the past six years, a total of 135 articles of RCT were published in Chinese Journal of Hepatobiliary Surgery, accounting for 8.7% in all clinical studies.The average number of RCTs in each issue was 1.88.The average time for publishing time delay was 450 days.The total number of citations in RCTs was 1252 and the average number of RCTs for citations was 9.3.53 RCT studies were financed, accounting for 39% of the total number of research papers.Beijing Friendship Hospital attached to the Capital University of Medical Sciences had published 8 papers of RCT and it is the institution of publishing the largest number of such papers in the journal.The number of multi-center study for RCTs was one and all RCT studies had significant conclusions.The average research duraton in RCTs was 45 months.The total number of patients in 33 clinical RCTs was 2705 and the average number of patients recruited in each RCT was 82.Conclusion Chinese Journal of Hepatobiliary Surgery put emphasis on the strongest evidence and the most valuable RCT researches that have great significance in the field of domestic hepatobiliary surgery for clinical treatment and experimental research.
RESUMO
Objective To evaluate the radical effect and prognosis of laparoscopic resection for colorectal cancer in China.Methods Articles of non.randomized comparative studies(NRCs)of laparoscopic resection and open Burgery for colorectal cancer which were published before October 2007 were retrieved,and correlated indexeswere extraeted for meta.analysis.Results The mean quality score of the 14 articles selected was 18.92±1.27.The basic characteristics of patients in laparoscopic resection group were similar to those in open surgery group.Compared with open surgery group,the incised length of the intestine in the laparoscopic resection group was shorter by 0.66 cm.and the distance between distal margin of resection and tumor was farther by 0.26 cm.The 2-year survival rate of patients in laparoscopic group Was 1.67 times higher than that of open surgery group.There was no significant difference upon follow-up rate,tumor diameter,number of resected lymph nodes,local recurrence rate and distal metastasis rate between the 2 groups.Conclusions The results of meta-analysis show that laparoscopic resection has the sanle radical effect as open surgery for colorectal cancer.but the 2-year survival rate of patients treated by laparoscopic resection is comparatively higher.
