To evaluate the charasteristics and risk factors of hospital infections in patients with contagious diseases, 489 patients with contagious diseases were analyzed. Among 18 patients who contracted hospital infections, 17 were suffering from chronic hepatitis. 77 78% of them were over 40 years old. Infection of ascitic fluid, lower respiratory tract, and blood stream comprised 77 78% of the infections. Most of the doctors used antibiotics empirically. The survey showed that patients over 40 years old in an infectious diseases hospital were vulnerable to hospital infections. Hospital infection often occurred in the abdomen, lower respiratory tract, and blood stream. Abdominal paracentesis liver puncture biopsy, and lumbar puncture were the first three exogenous risk factors.

Objective: To investigate the clinical research of Guo's Liulian therapy in treating acute pancreatitis intestinal mucosal barrier dysfunction and provide reference for the patients with acute pancreatitis. Methods: The 68 patients with acute pancreatitis who were admitted to our hospital from September 2016 to May 2018 were selected as study subjects. According to the random number table method, the patients were divided into the observation group and the control group, with 34 cases in each group. The patients in the control group were treated with conventional western medicine. The patients in the observation group were treated with Guo's Liulian therapy on the basis of the above treatment. The time of intestinal paralysis was compared between the two groups. The changes of intestinal mucosal barrier function and serum inflammatory factor related indexes before and after treatment were analyzed in the two groups. The difference of therapeutic effects between the two groups was observed. Results: In the observation group, the abdominal pain relief time, abdominal distention relief time, bowel sound recovery time, and first bowel anus defecation time were significantly lower than those in the control group (t=7.621, 5.332 6.625, 8.762, all Ps<0.01). After treatment, serum LPS, DAO, ET, D-lactic acid, TNF-α, IL-1, IL-6, IL-8, and IL-10 and urine L/M were significantly lower in the observation group, while the serum ITF and MFG-E8 were significantly higher in the observation group (t=9.856, 6.974, 9.784, 16.068, 9.550, 12.506, 22.343, 16.625, 6.774, 23.469, 20.118, 23.031, all Ps<0.01). Conclusions The Guo's Liulian therapy treatment of acute pancreatitis in patients with intestinal mucosal barrier dysfunction can reduce the palsy remission time, reduce inflammation, increase serum ITF, MFG-E8 levels, repair of intestinal permeability, and improve the intestinal barrier function.

Objective To understand the incidence and death patterns of viral hepatitis in China and provide evidence for the prevention and control of viral hepatitis.Methods The analysis was conducted on the incidence and death data of viral hepatitis published by National Health and Family Planning Commission during 2004-2013.Results The incidences of viral hepatitis in Guizhou,Yunnan,Tibet,Gansu,Qinghai,Ningxia and Xinjiang provinces (autonomous region) were high.The major forms were hepatitis B (80.63/100 000) and hepatitis C (9.68/100 000),accounting for 80.90％ and 9.25％ of the total reported viral hepatitis cases respectively.The incidences of hepatitis A and unidentified hepatitis decreased and the incidence of hepatitis B,C and E increased during this period.During the 10 years,10 008 deaths caused by viral hepatitis were reported (1 001 deaths per year).The reported deaths caused by hepatitis A,hepatitis E and unidentified hepatitis decreased during this period.The reported deaths caused by hepatitis B were in a downward trend,but the constituent in total cases remained high.The reported deaths caused by hepatitis C were in an upward trend.Conclusion During 2004-2013,the overall incidence of viral hepatitis showed no downward trend in China.The incidence of hepatitis B remained high,and the incidence of hepatitis C showed an obvious upward trend.The overall death rate and case fatality rate of viral hepatitis showed a downward trend,but hepatitis B remained the main cause of viral hepatitis related death,and the death caused by hepatitis C was in increase.Hepatitis B and hepatitis C are the major targets in the prevention and treatment of viral hepatitis in China,and the 7 western provinces (autonomous region) with high incidences are the key regions of the prevention and control.

Objective To investigate the epidemiological characteristics of a family clustering of COVID-19. Methods Field epidemiological survey was conducted. Result Case 1 of the long-term residents from Hubei province was the source of infection of this family clustering. There were 6 cases (from case 2 to case 7) infected in the whole incubation period. The incubation period was more than 14 days for 3 of the second-generation cases. Routes of transmission include respiratory droplets (from case 1 transmitted to case 6, from case 1 to her family members) and closecontact (from case 1 to other cases in her family). All the age groups were generally susceptible, while elderly were easier to progress to critically ill. Besides respiratory symptoms, there were also gastrointestinal symptoms, of which diarrhea was the most common one. Conclusion Family clustering had been an important part for COVID-19 cases.

OBJECTIVE: To summarize and analyze the postoperative short-term complications of laparoscope-assisted transanal total mesorectal excision (taTME) for rectal cancer patients after neoadjuvant therapy. METHODS: A prospectively established database on taTME patients at Peking University Cancer Hospital was screened with the following conditions: data retrieval from June 2016 to August 2018, pathologically confirmed adenocarcinoma, receiving preoperative neoadjuvant chemoradiotherapy or chemotherapy. The transabdominal procedure and the transanal procedure were performed simultaneously in the taTME operation. Occurrence of complications during perioperative period (within postoperative 3 months) in these patients, especially anastomosis-related complications and their management were analyzed. The relevant complications were recorded according to the Clavien-Dindo (CD) grading criteria. The severity of anastomotic leakage and anastomotic stenosis was evaluated according to criteria developed by the International Rectal Cancer Research Group. RESULTS: A total of 29 patients were enrolled in this study. In the 29 patients, 25 (86.2%) were male and 4 (13.8%) were female, the median age was 60 (range, 30 to 72) years, the median body mass index was 25.8 (range, 19.8 to 36.4) kg/m, the median distance from the tumor to anal verge was 4 (range, 2 to 8) cm. All the patients completed laparoscope-assisted taTME operations successfully without conversion to laparotomy, intra-operative severe complication or death. The median operation time was 300 (range, 198 to 405) minutes, and the median intra-operative blood loss was 100 (range, 50 to 200) ml. All the TME specimens were complete according to the Nagtegaal standard. All the patients underwent prophylactic ileostomy. Hartmann procedure was performed in one case due to poor blood supply in the proximal bowel without the possibility of anastomosis. Anal sphincter preservation rate was 96.6% (28/29). The median postoperative exhaust time was 2 (range, 1 to 10) days, and the median postoperative hospital stay was 9 (range, 7 to 24) days. Fifteen patients (51.7%) had postoperative complications, among which serious complication (CD grade IIIb and above) accounted for 6.9% (2/29). No perioperative death was observed. Five patients (17.2%) presented anastomosis-related complications, including 2 cases of grade C anastomotic leakage due to anastomotic rupture, who underwent abdominal perineal resection 1 month after operation; 2 cases of grade B anastomotic leakage, who improved after conservative treatment; 1 case of grade A anastomotic stenosis, who improved with anal expansion 1 month after operation. The incidence of postoperative infection was 24.1% (7/29), including 6 cases of pelvic infection and 1 case of trocar site infection, all of which were CD grade II. One case had incomplete intestinal obstruction (CD grade II); 1 case had gastroplegia; 1 case had abdominal trocar hernia. All the patients were followed up for a median of 12.0 (range, 3.9 to 29.9) months. Seven cases did not undergo ileal stoma closure. The anal sphincter preservation rate was 75.9% (22/29). CONCLUSION Pelvic infection and anastomosis-related complications are common after laparoscope-assisted taTME surgery for rectal cancer patients following neoadjuvant chemoradiotherapy, which require active management and appropriate treatment.
