Objective To evaluate the linkage between the proxmal as well as long term outcome and choice of therapeutical modality for benign hilar stricture of bile duct prospectively. Methods 25 patients have been catergorized into 4 groups according to different pathogen and the proxmal as well as long term outcome after pathogen based management have been studied prospectively. Results The hepatic portal cholangio-jejunostomy applied for iatrogenic hilar stricture of bile duct has been proved to be effective and the incidence of refulux cholangitis is only 10%(1/10). Hepatic hilar plasty procedures keep the physiological entitity of bile duct and the vital, sufficient autologous repair materials as well as reliable operation design are needed. Resection of atrophic right liver lobe bearing hepatolithiasis combined hepatic hilar plasty has reached both elimination of liver focus and maintaining the physiological entitity of bile duct. The ballon dilation for mild ring-like hilar stricture of bile duct is valide but not for hilar tubular stricture of secondary sclerosing cholangitis.Conclusion The strategy of individualized management (pathogen based management) for benign hilar stricture of bile duct has proved to be reliable and effective.
ObjectiveTo systematically review the efficacy and safety of recombinant human TSH (rhTSH) in radioiodine therapy for benign thyroid goiter.
MethodsWe electronically searched MEDLINE, EBSCO, The Cochrane Library (Issue 6, 2015) and CNKI databases from January 1990 to March 2015, to identify randomized controlled trials (RCTs) about rhTSH in radioiodine therapy of benign thyroid goiter. Two reviewers independently screened literature, extracted data and evaluated the risk of bias of included studies, and then meta-analysis was performed by using RevMan 5.3 software.
ResultsA total of 6 RCTs were included. The results of meta-analysis showed that: compared with the control group, the thyroid volume was significantly reduced at 1 year after radiation in the rhTSH group (MD=0.14, 95%CI 0.05 to 0.23, P=0.002). There were no significant differences in FT4, FT3 and the percentage of patients who had thyroid antibody between two groups before and after radiation. In addition, rhTSH did not significantly increase the incidence of hyperthyroidism and neck pain.
ConclusionrhTSH is effective and safe in radioiodine therapy of benign thyroid goiter. Due to the limitation of quality and quantity of the included studies, more high quality studies are needed to verify the above conclusion.
Objective To observe the expression and localization of cellular homolog FLICE-like inhibitory protein (c-FLIP) in the procedure of benign biliary stricture formation and discuss the significances. Methods The method of in situ hybridization was used in anastomotic tissues from 15 dogs (experimental group) in 2, 3, 4, 5, 6 months after bile duct injury and 15 matching sham operation dogs (sham operation group) for analyzing the expression and localization of c-FLIP and calculating the average integrated optical density of each slice. Stain cells were counted under the magnification field (×400) and at least 5 fields per slice were examined. The cells stained red in the nuclei and (or) the cytoplasm were positive cells. The signals meant: Negative for cells no stained, weak positive for the cells with nuclei and (or) cytoplasm stained pink; b positive for the cells stained the bright red; while middle positive for the cells stained between the both. The image analysis software （Image pro plus 4.5） was applied in the gland tissue and interstitial tissue in each slice to calculate the average integrated optical density for the expression of c-FLIP. Results In the experimental group, there were all b positive expressions of c-FLIP in the interstitial tissue at all the time points, mainly expressed in the cytoplasm of fibroblast and very little or almost no expression in the glandular tissue. Positive expression of c-FLIP in the interstitial tissue was significantly ber than that of gland tissue (Plt;0.05); There were no significant differences among each time point in either the interstitial tissue or gland tissue (Pgt;0.05). In the sham operation group, there were all weak positive expressions of c-FLIP in the interstitial tissue and gland tissue at all the time points and was no significant difference (Pgt;0.05), no difference between each phase (Pgt;0.05). The expression of c-FLIP in the experimental group was significantly higher than that in the sham operation group in the interstitial tissue at all the time (Plt;0.05), while no significant that in the gland tissue (Pgt;0.05). Conclusion After bile duct injury, the expression of c-FLIP in anastomotic interstitial tissue is sustainable, by which the continuing obstruction effect to apoptosis may have a close relationship with the formation of biliary benign stricture.
ObjectiveTo explore the surgical technique and clinical effect of endoscopic assisted transaxillary breast tumor resection in the treatment of benign and malignant breast tumors. MethodsThe clinical data of 18 patients received endoscopic breast tumor resection from September 2020 to December 2021 in the Department of Breast Surgery, West China Hospital, Sichuan University, were retrospectively analyzed to evaluate the feasibility, tumor safety and postoperative cosmetic effect. There were 7 patients with benign breast tumors (a benign breast tumor group) and 11 patients with early breast cancer (a malignant breast tumor group). Breast-Q and Scar-Q questionnaires were used to evaluate postoperative quality of life and satisfaction of patients. ResultsEndoscopic breast tumor resection was performed successfully in 18 female patients, among whom 12 patients received day surgery. The mean age of benign and malignant breast tumor groups was 29.6±11.6 years and 46.7±14.3 years, the mean tumor size in pathological examination was 3.3±2.1 cm and 2.0±0.8 cm, and the operative time was 138.9±57.0 min and 177.3±46.3 min, respectively. One patient had positive resection margin and underwent intraoperative extended resection in the malignant breast tumor group. All the patients were successfully followed up, and the mean follow-up time of benign and malignant breast tumor groups was 6.8±4.0 months and 8.7±4.9 months, respectively. No complications or tumor recurrence occurred. The scores of psychosocial status, sexual well-being, chest wall status and breast satisfaction decreased one month after surgery and basically recovered to the preoperative level in one year, and the score of scar appearance increased to 64.6±5.9 points one year postoperatively. ConclusionEndoscopic assisted transaxillary breast tumor resection can effectively improve postoperative cosmetic effect and patient satisfaction on the premise of safety.

【Abstract】Objective To investigate the safety and clinical significance of total thyroidectomy performed for benign thyroid disease. Methods Eighty-eight patients with benign thyroid disease were treated with total thyroidectomy. The postoperative complications were analyzed. Results With primary total thyroidectomy, the incidences of transient hypocalcemia and transient recurrent laryngeal nerve paralysis were 2.5% and 1.2% respectively. The incidences after reoperation were 28.6%（P＜0.05）and 28.6%（P＜0.01）respectively. No patients had permanent hypoparathyroidism and permanent recurrent laryngeal nerve injury. Conclusion Total thyroidectomy can be performed safely. It can avoid reoperation for the recurrence caused by the remainder thyroid.
Eight cases of gastric remnant carcinoma are reported and its possible etiology, course of disease, prevention and treatmant are discussed together with literature review. Duodenal ulcer, except with serious complications, should be treated conservatively. For benign gastric ulcer gastrectomy may be considered in individual case, but the operative indication can be controlled by its lesions. Regular follow-up study should be performed on patients who had gastrectomy for more than five years.
ObjectiveTo investigate the expression of histone deacetylase 2 (HDAC2) in animal model of benign tracheal stenosis, and explore the mechanism of HDAC2 in development of tracheal stenosis.MethodsEighteen rabbits were randomly divided into a blank control group, a model group, and an erythromycin group, with 6 rats in each group. The model group and the erythromycin group underwent tracheostomy, the inner wall of trachea was brushed back and forth with a nylon brush for more than 20 times to induce benign tracheal stenosis. From 7 days before surgery to 9 days after surgery, the model group received gavage with saline, the erythromycin group received gavage with low-dose erythromycin in dose of 15 mg·kg–1·d–1, and the control group did not receive any treatment. On the 10th day after operation, all the rabbits were sacrificed and the trachea was cut to measure the tracheal stenosis. RNA and protein were extracted from the granulation tissue in the stenosis and the relative mRNA expressions of HDAC2, interleukin (IL)-6 and IL-8 in the granulation tissue were detected by real-time fluorescence quantitative PCR. The relative expression of HDAC2 protein was detected by Western blot.ResultsCompared with the blank control group, the tracheal stenosis in the model group was more obvious [(84.60±1.14)% vs.(27.00±6.44)%], the mRNA and protein expressions of HDAC2 were decreased (0.29±0.07 vs. 1.00±0.00, 0.20±0.02 vs. 0.49±0.04), the mRNA expressions of IL-6 and IL-8 were up-regulated (4.22±0.67 vs. 1.00±0.00, 162.72±23.23 vs.1.00±0.00). Compared with the model group, tracheal stenosis in the erythromycin group was relieved [(64.00±12.25)% vs. (84.60±1.14)%], the mRNA and protein expressions of HDAC2 were increased (0.42±0.14 vs. 0.29±0.07, 0.43±0.01 vs. 0.20±0.02), the mRNA expressions of IL-6 and IL-8 were decreased (0.72±0.24 vs. 4.22±0.67, 130.22±7.93 vs. 162.72±23.23). All the differences were statistically significant (all P<0.05). The Pearson correlation coefficient between tracheal stenosis and HDAC2 mRNA relative expression was –0.96 (P<0.05).ConclusionsThe down-regulation of HDAC2 expression in model of benign tracheal stenosis is related to the occurrence and development of tracheal stenosis. The low dose of erythromycin may be used to treat benign tracheal stenosis by up-regulating expression of HDAC2 and thus inhibiting the inflammatory disorder during tracheal injury repair.
