RESUMEN

Objective: To compare the safety and clinical efficacy of endoscopic and surgical treatment of patients with delayed iatrogenic bile duct injury (DBDI) with severity (SG) grade 1 to 2. Methods: The clinical data of 129 patients with SG grade 1 to 2 DBDI who received endoscopic or surgical treatment in the First Hospital of Lanzhou University from November 2007 to November 2021 were retrospectively collected. There were 46 males and 83 females,aged (M(IQR)) 54(22)years(range: 21 to 82 years). The baseline data of the two groups were matched 1∶1 by propensity score matching(caliper value was 0.2). Independent sample t test,rank sum test,χ2 test or Fisher exact probability test were used to analyze the data of the two matched groups. Results: There were 48 patients in each of the endoscopic treatment and surgical groups after matching,and there was no difference in general information between the two groups(both P>0.05). The bile duct injury-repair interval and intraoperative anesthesia complications were not statistically significant between the two groups after matching(all P>0.05). Compared with the surgical group, patients in the endoscopic treatment group had significantly shorter operative time(50 (30) minutes vs. 185 (100) minutes, Z=7.675,P<0.01) and postoperative hospital stay(5 (5) days vs. 12 (7) days, Z=5.848, P<0.01).For safety,there was no statistical difference in the incidence of immediate postoperative complications between the two groups with Clavien-Dindo classification of surgical complications<Ⅲ;the incidence of serious postoperative complications (Clavien-Dindo classification of surgical complications≥Ⅲ) was significantly higher in the surgical group than in the endoscopic treatment group(P=0.012). The incidence of long-term postoperative complications was not statistically different between the two groups(28.1% vs. 20.7%,P=0.562). In terms of efficacy,the postoperative liver function indexes of patients in both groups improved significantly compared with the preoperative period and returned to normal or near normal levels; the postoperative infection indexes of both groups showed an increasing trend,but were within the normal range. Of the 96 patients in both groups,61 obtained follow-up,and the follow-up time was (89.4±48.0)months(range: 3 to 165 months),and there was no statistical difference between the two groups(P=0.079). The probability of excellent long-term follow-up (78.1% vs. 86.2%) was not statistically different between the two groups(P=0.412).In patients with Strasberg-Bismuth type E1,the probability of excellent long-term follow-up was higher in the endoscopic treatment group compared with the surgical group(13/14 vs. 2/5,P=0.037). Conclusions: For DBDI patients with SG grade 1 to 2 and bile duct continuity,endoscopy can be used as the first deterministic treatment. The advantages of endoscopic therapy compared to surgery are the lower incidence of postoperative serious complications,and the shorter duration of surgery and postoperative hospital stay.

RESUMEN

OBJECTIVE: To characterize the species of invasive Pomacea snails that were discovered for the first time in Shandong Province. METHODS: Pomacea snails samples were collected in the field of Jining City, Shandong Province on October 2021 for morphological identification. Pomacea snails were randomly sampled and genomic DNA was extracted from foot muscle tissues of Pomacea snails for multiplex PCR amplification. The PCR amplification product was sequenced. Then, the sequence was aligned and a phylogenetic tree was created using the software MegAlign 7.1.0. In addition, Angiostongylus cantonensis infection was detected in Pomacea snails with the lung microscopy. RESULTS: A total of 104 living Pomacea snails were collected, and all were characterized as Pomacea spp. based on morphological features. Of 12 randomly selected adult Pomacea snails, multiplex PCR assay and sequencing identified eleven snails as P. canaliculata and one as P. maculata. No A. cantonensis infection was detected in 104 Pomacea snails. CONCLUSIONS: This is the first report of invasive Pomacea snails in Shandong Province, where P. canaliculata and P. maculata are found.

RESUMEN

PURPOSE: Continuing medical education (CME) is a compulsory requirement for every health professional. However, to date, little is known about the effectiveness of CME in Vietnam. This study assessed CME programs based on attendees' perception and evaluation. METHODS: A cross-sectional study was conducted during a five-month period in all 62 CME courses at a university hospital. A self-report, anonymous questionnaire was distributed to the participants during the course and was collected at the end of the course. The questionnaire included questions about demographic characteristics, experiences during the course and participants' perception and evaluation as measured by the 19-item Program Evaluation Instrument (PEI). A higher score on the PEI indicates a higher level of positive reaction toward CME programs. RESULTS: Among 1312 participants in the analysis, the majority were females (58.1%) with a mean age of 34.5 (SD = 10.6) years. Almost all participants had good, positive perceptions toward CME. However, about 5% of participants reported CME a waste of time. Participants reported a high score on the PEI (95.0±8.9) and all four dimensions including program objectives (20.7±2.2), learner's objectives (18.8±2.3), teacher's behavior (25.7±2.7) and program satisfaction (29.7±3.4). While there was no association between demographic characteristics and PEI score, attendance rate during the courses and perceptions toward CME were positively associated with PEI score. CONCLUSION: CME programs receive positive reaction and evaluation from healthcare professionals and are helpful in providing and updating knowledge, attitude and practice in Vietnam. However, further studies are needed in other settings and specialties to fully understand the effectiveness of CME in Vietnam.

RESUMEN

Earlier experimental data in our laboratory showed that introduction of an exogenous protein into early chicken embryonic blood leads to immunotolerance of hatched chicken to that protein. However, the underlying mechanism is yet unknown. In the present study, we show that the blood cells collecting circulating antigen might contribute to the establishment of immunotolerance. In this experiment, most of the chicken embryo blood cells took up injected fluorescein isothiocyanate-BSA at approximately embryonic d 3. At the same stage, 1 microL of embryo blood was taken out and incubated with BSA. After being loaded with BSA in vitro and washed, these cells were injected back into the original embryo. The BSA-specific lymphocytes were depleted in chickens whose early embryo cells had been loaded with BSA, as evidenced by a significant decrease in anti-BSA antibody after challenge with BSA when the chickens were 3 wk old. In addition, by direct injection of BSA to embryonic d 3 embryo blood, the hatched chickens had decreased amounts of anti-trinitrophenol antibody after the chickens were challenged with trinitrophenol-BSA, indicating that the helper function of BSA-specific T cells was impaired. In conclusion, these observations suggest that some early embryo blood cells possibly collect and store antigen for the establishment of self-tolerance before the maturation of B and T cells.

RESUMEN

During 1985 a survey of the physical growth of 175,290 Chinese children less than 7 years in age was undertaken in the urban and rural areas of ten provinces. The results of weight, height, and head circumference are similar to those generally found as regards the differences between boys and girls. The children in rural areas were lighter and shorter. From the age of 3-6 months onwards the weights and heights of all groups were less than international standards. Nutrition is probably the major factor in these differences in growth.
