ABSTRACT
ObjectiveTo determine the epidemiological characteristics and risk factors of a norovirus GII.17 outbreak in Minhang District of Shanghai in 2018， and provide evidence for prevention and control measures of norovirus infection. MethodsDescriptive epidemiological analysis was performed. In addition， a retrospective cohort study was conducted to determine the risk factors. ResultsFrom May 30th to June 1st of 2018， a total of 132 cases （126 clinical cases and 6 confirmed cases） were documented，with an attack rate of 29.20%（132/452）.All cases were children in a kindergarten， with the average age of 5 years and 43.9% being male. The cases were reported in all the classes， with no clustering by class or floor．The epidemic curve was characterized by a point source exposure， which was estimated to be probably between 7 AM on May 30thand 0：30 AM on May 31st. The retrospective cohort study showed that the attack rate significantly differed between the children who had taken and did not take the school lunch （RR=∞） on May 30th，and those who had taken and did not take seafood noodles （RR=4.11， 95%CI：1.09-15.55） （P<0.05）. Among a total of 73 specimens， six specimens collected in child cases and one specimen in an asymptomatic chef tested positive for GII.17 type of norovirus. In addition， one retained food specimen of seafood noodles was positive for Aeromonas hydrophila. Viral shedding in the asymptomatic chef remained over 30 days. ConclusionThe outbreak was caused by seafood noodles contaminated by norovirus. It warrants enhancement in the regulation of food safety in canteens and regular examination of norovirus infection in catering industry employees.
ABSTRACT
Thermal ablation, including radiofrequency ablation and microwave ablation, is a frequently used method for local treatment of primary liver cancer with a marked clinical effect, and it has been widely used in clinical practice in recent years. Diaphragmatic hernia is a rare complication of thermal ablation, but its incidence rate tends to gradually increase in recent years. This article reviews the cases of diaphragmatic hernia after thermal ablation for primary liver cancer in China and globally and elaborates on possible risk factors, diagnosis and treatment, and prevention strategies, so as to improve the understanding of diaphragmatic hernia after thermal ablation for primary liver cancer among clinicians and achieve the goal of preoperative prevention, rapid diagnosis and intervention, and reduced mortality rate.
ABSTRACT
The development of liver inflammatory diseases is associated with autoimmunity and inflammatory response. As a negative feedback regulator of cell signal, suppressor of cytokine signaling 1 (SOCS1) plays a key role in the development and progression of inflammatory diseases. This article mainly introduces the mechanism of action of SOCS1 in autoimmunity and inflammatory response and briefly describes its role in the development and progression of liver inflammatory diseases such as viral hepatitis and nonalcoholic steatohepatitis. The analysis shows that the abnormal expression of SOCS1 in inflammatory response is associated with the regulation of cytokine receptor, Toll-like receptor, and hormone receptor signal, which leads to the development of inflammatory diseases. Therefore, SOCS1 has potential prospects as an auxiliary means for the diagnosis and treatment of liver inflammatory diseases.
ABSTRACT
Portal hypertension refers to a series of clinical manifestations caused by elevated pressure of the portal vein system, which can cause portal hypertension by causing portal venous obstruction and / or increased blood flow. A typical clinical manifestation in patients with decompensated cirrhosis is portal hypertension. A severe complication of portal hypertension is esophagogastric varices bleeding, refractory ascites, and hepatic encephalopathy. The effective reduction of portal pressure can reduce the incidence of complications, improve the prognosis and reduce the mortality. At present, the commonly used clinical methods for reducing portal hypertension include drug therapy, minimally invasive interventions, surgical treatment, and liver transplantation. This article reviews the current status of integrated traditional Chinese and Western medicine for portal hypertension.
ABSTRACT
Objective To summarize the strategies for nursing cooperation in repair of interrupted aortic arch(IAA)in infants. Method The clinical data of 5 infants undergoing repair of interrupted aortic arch under profound hypothermia and extracorporeal circulation were retrospectively reviewed to summarize the key points,methods and experience in the nursing cooperation during operation.Result All the infants underwent the repairs smoothly and sent back to ICU with tracheal intubation safely after operation. Conclusion The intraoperative nursing strategies like elaborate preoperative preparation,proper body position and skilled operative cooperation are critical for the shortened time for the repairs,improve operative prognosis and the smooth completion of the repairs.
