Analysis of Key Points of Technical Review of Traditional Chinese Medicine Fumigation Treatment Device / 中国医疗器械杂志

Traditional Chinese medicine fumigation device is the carrier of traditional Chinese medicine fumigation treatment. In recent years, with the rapid development of new technology and new materials, the development of fumigation device changes with each passing day, and a variety of new products continue to emerge. However, at present, the lack of corresponding evaluation norms, resulting in some difficulties in the registration, marketing, quality control, evaluation scale and other aspects of the product. Some products have many disadvantages in clinical use. From the perspective of technical review, this paper elaborates and analyzes the main concerns in technical review, such as product structure, main risks, performance requirements, clinical evaluation, etc., in order to provide a basis for the design, development, production, registration, use and post-marketing supervision of the devices.

Multiresolution discrete optimization registration method of ultrasound and magnetic resonance images based on key points / 生物医学工程学杂志

The registration of preoperative magnetic resonance (MR) images and intraoperative ultrasound (US) images is very important in the planning of brain tumor surgery and during surgery. Considering that the two-modality images have different intensity range and resolution, and the US images are degraded by lots of speckle noises, a self-similarity context (SSC) descriptor based on local neighborhood information was adopted to define the similarity measure. The ultrasound images were considered as the reference, the corners were extracted as the key points using three-dimensional differential operators, and the dense displacement sampling discrete optimization algorithm was adopted for registration. The whole registration process was divided into two stages including the affine registration and the elastic registration. In the affine registration stage, the image was decomposed using multi-resolution scheme, and in the elastic registration stage, the displacement vectors of key points were regularized using the minimum convolution and mean field reasoning strategies. The registration experiment was performed on the preoperative MR images and intraoperative US images of 22 patients. The overall error after affine registration was (1.57 ± 0.30) mm, and the average computation time of each pair of images was only 1.36 s; while the overall error after elastic registration was further reduced to (1.40 ± 0.28) mm, and the average registration time was 1.53 s. The experimental results show that the proposed method has prominent registration accuracy and high computational efficiency.

Epidemiological characteristics of scarlet fever in Putuo District， Shanghai from 2015 to 2020 / 上海预防医学

ObjectiveTo analyze the epidemiological characteristics of scarlet fever in Putuo District， Shanghai from 2015 to 2020， and provide a basis for formulating effective prevention and control measures. MethodsThe data of scarlet fever cases from January 1， 2015 to December 31， 2020 in Putuo District， Shanghai were obtained from the Infectious Disease Reporting Information Management System of the Chinese center for disease control and prevention （CDC）. Descriptive epidemiological method was used to analyze the epidemiological characteristics of scarlet fever cases in Putuo District， Shanghai by time， population， and region. ResultsA total of 586 scarlet fever cases were reported in Putuo District from 2015 to 2020， with an average annual reported incidence of 7.39 per 105， an average age of onset of 6.2±1.8 years， and a male/female ratio of 1.6∶1. The incidence of scarlet fever has declined significantly in 2020， which was 5.44 per 105 lower than the average reported incidence in 2015‒2020. The incidence peak was from April to June and November to January of the following year， which was characterized by high incidence in spring and winter. The age distribution of cases was concentrated at the age of 4‒9 years， mainly children in kindergarten and primary school students. Areas with high reported incidence rates were Wanli Street， Changzheng Town， Taopu Town and Changfeng New Village Street. ConclusionThe peak incidence of scarlet fever in Putuo District is from April to June and November to January of the following year， with children in kindergartens and students in primary school as the key populations. We should strengthen epidemic monitoring and guidance of prevention and control for in kindergartens and schools before the high incidence season of scarlet fever， so as to effectively prevent the epidemic of the disease.

Laparoscopic radical right hemicolectomy via medial approach for colon cancer / 中华消化外科杂志

Objective To explore the surgical techniques and key points of laparoscopic radical right hemicolectomy for colon cancer.Methods The clinical data of 84 patients with colon cancer who underwent laparoscopic radical right hemicolectomy at the General Hospital of Lanzhou Military Command from November 2012 to June 2014 were retrospectively analyzed.The tumors were located at the hepatic flexure of the colon,the ascending colon and the ileocecum.The inside-out and up-down medial approach was used as the main surgical approach,and D3 lymph node dissection based on a center of surgical trunk of the superior mesenteric vein was the key point of laparoscopic radical right hemicolectomy.The intraoperative and postoperative conditions of patients were observed.Patients were followed up by telephone interview,text message and examination of readmission till March 2015.Results Of 84 patients,82 received laparoscopic radical right hemicolectomy and 2 were converted to open operation without perioperative death.The mean operation time,volume of intraoperative blood loss,number of lymph node dissection,postoperative gastrointestinal recovery time and duration of hospital stay were 125 minutes (range,110-175 minutes),50 mL (range,30-120 mL),17 (range,13-20),52 hours (range,24-72 hours) and 6 days (range,5-10 days),respectively.There were no complications such as ureter injury,duodenal injury,anastomotic fistula,abdominal abscess and surgery-related complications.Seventy-two patients were followed up for a median time of 21 months (range,12-28 months) without the tumor metastasis of abdominal incision and sites of puncture.Conclusion Laparoscopic radical right hemicolectomy via the medial approach is safe and feasible as well as improving the prognosis of patients,and lymph node dissection based on a center of surgical trunk of the superior mesenteric vein is the key point of surgery.
