RESUMO
Objective: To explore the improvement rate of liver fibrosis in patients with chronic hepatitis B virus infection who received entecavir alone or in combination with anluohuaxianwan for 78 weeks. Methods: Patients with chronic HBV infection were randomly treated with entecavir alone or in combination with anluohuaxian for 78 weeks. Ishak fibrosis score was used for blind interpretation of liver biopsy specimens. The improvement in liver fibrosis condition before and after the treatment was compared. Student's t test and non-parametric test (Mann-Whitney U-Test and Kruskal-Wallis test) were used to analyze the measurement data. The categorical variables were analyzed by Chi-square test method and Spearman's rank correlation coefficient was used to test bivariate associations. Results: Liver fibrosis improvement rate after 78 weeks of treatment was 36.53% (80/219) and the progression rate was 23.29% (51/219). The improvement of liver fibrosis was associated to the degree of baseline fibrosis and treatment methods (P < 0.05). The improvement rate of hepatic fibrosis in patients treated with anluohuaxianwan combined with entecavir at baseline F < 3 (54.74%, 52/95) was significantly higher than that in patients treated only with entecavir (33.33%, 16/48), P = 0.016 and the progression rate of hepatic fibrosis (13.68%, 13/95) was lower than that in patients treated alone (18.75%, 9/48), P = 0.466. In patients with baseline F < 3, the proportion of patients with improved and stable liver fibrosis in the combined treatment group (68.1%, 32/47) was higher than that in the treatment group alone (51.7%, 15/29). Conclusion: Combined anluohuaxianwan and entecavir treatment can significantly improve the improvement rate of liver fibrosis in patients with chronic hepatitis B virus infection. Furthermore, it has the tendency to improve the stability rate and reduce the rate of progression of liver fibrosis.

Objective: To explore the efficacy and feasibility of transanal hand-sewn reinforcement of low stapled anastomosis in preventing anastomotic leak after transanal total mesorectal excision (taTME). Methods: A descriptive cohort study was conducted. Clinical data of 51 patients with rectal cancer who underwent taTME with transanal hand-sewn reinforcement of low stapled anastomosis at Department of Colorectal Surgery, the Sixth Affiliated Hospital of Sun Yat-sen University from January 2019 to December 2020 were retrospectively collected. Inclusion criteria: (1) age >18 years old; (2) rectal cancer confirmed by preoperative pathology; (3) distance from tumor to anal verge ≤ 8 cm according to pelvic MR; (4) the lesion was evaluated to be resectable before operation; (5) with or without neoadjuvant chemotherapy and radiotherapy; (6) taTME, end-to-end stapled anastomosis, and reinforcement in the anastomosis with absorbable thread intermittently were performed, and the distance between anastomosis and anal verge was ≤ 5 cm. Exclusion criteria: (1) previous history of colorectal cancer surgery; (2) emergency surgery due to intestinal obstruction, bleeding or perforation; (3) patients with local recurrence or distant metastasis; (4) the period of postoperative follow-up less than 3 months. The procedure of transanal hand-sewn reinforcement was as follows: firstly, no sign of bleeding was confirmed after checking the anastomosis. Then, the anastomosis was reinforced by suturing the muscle layer of rectum intermittently in a figure-of-eight manner using 3-0 single Vicryl. The entry site of the next suture was close next to the exit site of the last one. Any weak point of the anastomosis could also be reinforced according to the specimen from the circular stapler. The primary outcome were the incidence of anastomotic leak, methods of the secondary operation, anastomotic infection, anastomotic stricture, and conditions of Intraoperative and postoperative. Results: All the 51 enrolled patients completed surgery successfully without any conversion to open surgery. The median operative time was 169 (109-337) minutes, and the median intraoperative blood loss was 50 (10-600) ml. The median postoperative hospital stay was 8 (5-16) days. The mssorectum was complete and distal resection margin was negative in all patients. Postive circumferential resection margin was observed in 1 patients (2.0%). Twelve (23.5%) patients underwent prophylactic ileostomy. One patient developed anastomosis stricture which was cured by digital dilatation of the anastomosis. ISREC grade C anastomotic leak was observed in 3 (5.9%) male patients, of whom 2 cases did not received prophylactic ileostomy during the operation, and were cured by a second operation with the ileostomy and anastomotic repair. The other one healed by transanal repair of the anastomosis and anti-infection therapy. One (2.0%) patient suffered from perianal infection and healed by sitz bath and anti-infection therapy. No death was reported within 30 days after operation. Conclusion: Transanal hand-sewn reinforcement in low rectal stapled anastomosis in preventing anastomotic leak after taTME is safe and feasible.

Patients with isolated serum transaminase elevations of unknown cause are common in China. An outbreak of such disease took place in a technicians' school during 1996. To define the epidemic and determine the etiology, a study was carried out, which included investigation of epidemiological, clinical and histological features. The symptoms of this disease were mild. The major clinical feature was transaminase elevation, and all serum markers of known hepatitis viruses were negative. Although the course of disease in most patients was self-limiting, in a few it was prolonged and relapsed. Histological findings were mild portal hepatitis or non-specific reactive hepatitis. The disease first appeared in 1994, and this outbreak occurred after October 1996. A total of 381 people were affected and the prevalence was as high as 60.7%. Casual contact and small-scale food transmission were considered to be risk factors for infection and the epidemic was under control 2 months later following the introduction of preventive measures for gastroenteric infection. Viral genomic fragments from the so-called transfusion-transmitted virus (TTV) were detected in acute-phase sera and stool samples collected 2 weeks before onset. Therefore, this disease outbreak might be another form of enterically transmitted viral hepatitis, not related to hepatitis A and E.
