Objective To analyze the characteristics of imported malaria epidemic from overseas in Wuhan, to explore the management mechanism of on-site cases, and to accumulate experience for the treatment of imported malaria in large cities after malaria elimination. Methods The epidemiological data on imported malaria from abroad during the period of malaria elimination (2010-2019) in Wuhan were collected. The gender, age and severe illness-related factors of the cases were analyzed. Based on the characteristics of the epidemic and the current situation of prevention and control, the content and experience of the “Municipal-District 24-7” case mechanism were discussed. Results The medical resources in Wuhan were the best in the central region, resulting in a large number of imported malaria cases, with a total of 474 cases reported from 2010 to 2019 (40.79% of the total number of cases in Hubei Province), including 359 cases of falciparum malaria, 36 severe cases and one death (the death rate was 0.28%). The patients were mainly young and middle-aged men aged 20 to 49 years old (97.26%). There were many referral cases (40.30%), and there was no seasonal clustering of cases reported. The undiagnosed proportion at the first visit was 44.85%, and the time of attack-diagnosis was 4 days or more in 61.00% of cases. The occurrence of severe cases was related to unconfirmed diagnosis at the first visit (χ2=35.46, P<0.001) and attack-diagnosis time (Z=-6.49, P<0.001). Conclusion Imported malaria occurs frequently in Wuhan, mainly falciparum malaria. However, “Municipal-District 24-7” case mechanism has effectively curbed the occurrence of severe and death cases and provided valuable experience for case management in similar cities in China.

Objective To establish the early warning model based on the control chart method for hand,foot and mouth disease (HFMD) in Wuchang District and to determine the optimum alarming threshold to provide the data support for HFMD monitoring work.Methods The data of HFMD in Wuchang District during 2009-2014 were collected from the National Infectious Diseases Notification System for constructing the data base.The mobile percentile method was adopted to establish the early alarming model,which was evaluated by the screening test.The sensitivity,specificity,positive predictive value and negative predictive value were calculated.Then the receiver operating characteristic (ROC) curve was drawn and the optimum alarming threshold was found out.Results The early alarming threshold of HFMD in Wuchang District was P90,its sensitivity,specificity,positive predictive value and negative predictive value were 75.00%,93.88%,50.00% and 97.87%,respectively.Conclusion Determining the early warning threshold should be optimized according to onset characteristics combining with the local epidemic situation,which pays attention to regional specificity and increases the monitoring ability of infectious diseases.

<p><b>OBJECTIVE</b>To evaluate clinical outcomes after laparoscopic total mesorectal excision (TME) combined with intersphincteric resection (ISR) for ultra-low rectal tumors.</p><p><b>METHODS</b>Clinical data of 36 patients with ultra-low rectal tumor undergoing laparoscopic TME combined with ISR were analyzed retrospectively.</p><p><b>RESULTS</b>The median distance from the inferior margin of the tumor to the anal verge was 3.4 (2.0-5.0) cm. There were 33 cases of well/moderately differentiated adenocarcinoma and 3 rectal malignant villous adenoma. There were 16 patients with stage I disease, 15 with stage II A, 3 with stage III A, and 1 with III B. Postoperatively, one patient developed stenosis at the end ileostomy and 3 anastomotic leakage. After a median follow-up of 16(4-49) months, one patient developed local recurrence at the anastomosis and one case died of liver metastasis. In the 19 patients who had a minimum follow-up of one year, the bowel movements frequency ranged from 1-4 times per day, and these patients were able to withhold defecation for more than 5 minutes.</p><p><b>CONCLUSIONS</b>Laparoscopic TME combined with ISR can achieve oncologic clearance, sphincter preservation, and minimal invasiveness for ultra-lower rectal cancer. However, patients selection should be cautious.</p>
