Objective To understand the epidemiologic characteristics and pathogen spectrum of hand,foot and mouth disease (HFMD) in Hunan Province during 2008-2017 and provide the basis for the prevention and control strategy of hand,foot and mouth disease.Methods Collecting data from national disease reporting information system throughout 2008-2017,the descriptive epidemiological method were used to analyze the data of HFMD monitoring and the result of pathogenic agent detection.Results A total of 1,255,530 HFMD cases were reported throughout 2008-2017,including 10097 severe cases and 394 deaths.The average annual attack rate is 190.38/100,000.The peak incidence of HFMD occurred in summer and fall.The reported incidence is on the rise.The number of critically ill and the number of deaths is declining.Proportion of male cases was higher than that of females.The majority of the children were those under 5 years of age.Enterovirus (EV)-A71,coxsackievirus (CV)-A16 and other other EV positive cases accounted for 33.29％,20.04％ and 46.67％ of laboratory diagnosed cases.Conclusions The epidemic of hand,foot and mouth disease in Hunan has obvious seasonal and population characteristics.There are different dominant pathogens causing HFMD in different years.

OBJECTIVE: To investigate the epidemiological situation and temporal-spatial clustering changes of hand-foot-mouth disease (HFMD) in Hunan.
 METHODS: Spatial autocorrelation and temporal-spatial clustering analysis were used to analyze the HFMD in Hunan.
 RESULTS: The incidence rates of HFMD ranged from 54.31/10 million to 318.06/10 million between 2009 and 2015 in Hunan. Cases mainly displayed in 5-year-old or even younger children and there were two epidemic periods each year. HFMD cases did not show a random distribution but with significant spatial aggregation. When local autocorrelation analysis was applied at the county/district level, 4 hot spots in Changsha, Yiyang, Loudi and Zhuzhou were discovered. The tendency for temporal and spatial clustering existed among HFMD cases in Hunan. The temporal dimension of HFMD was from April to July annually. Clustering areas gathered in the northern regions in 2009 and in the middle regions from 2010 to 2012. They moved to middle-southern regions in 2013 or 2014 and middle-western regions in 2015. 
 CONCLUSION The HFMD incidence from 2009 to 2015 in Hunan showed temporal and spatial clustering tendency, with the shifting trend of clustered areas toward south and west.

Traumatic cerebrospinal fluid leakage commonly presents in traumatic brain injury patients, and it may lead to complications such as meningitis, ventriculitis, brain abscess, subdural hematoma or tension pneumocephalus. When misdiagnosed or inappropriately treated, traumatic cerebrospinal fluid leakage may result in severe complications and may be life-threatening. Some traumatic cerebrospinal fluid leakage has concealed manifestations and is prone to misdiagnosis. Due to different sites and mechanisms of trauma and degree of cerebrospinal fluid leak, treatments for traumatic cerebrospinal fluid leakage varies greatly. Hence, the Craniocerebral Trauma Professional Group of Neurosurgery Branch of Chinese Medical Association and the Neurological Injury Professional Group of Trauma Branch of Chinese Medical Association organized relevant experts to formulate the " Chinese expert consensus on the diagnosis and treatment of traumatic cerebrospinal fluid leakage in adults ( version 2023)" based on existing clinical evidence and experience. The consensus consisted of 16 recommendations, covering the leakage diagnosis, localization, treatments, and intracranial infection prevention, so as to standardize the diagnosis and treatment of traumatic cerebrospinal fluid leakage and improve the overall prognosis of the patients.

Objective To analyze the spatial and temporal characteristics of hand, foot and mouth disease (HFMD) in Hunan Province from 2016 to 2020. Methods The data of HFMD in Hunan Province from 2016 to 2020 were collected from China's Disease Prevention and Control Information System. HFMD spatial autocorrelation analysis was conducted by ArcGIS 10.2 software at county level, and spatial-temporal scan statistical analysis was performed by SaTScan 9.7 software. Results A total of 714 157 cases was reported in Hunan Province during 2016-2020, with an average annual incidence rate of 208.36/100 000. Global spatial autocorrelation showed that HFMD had a positive spatial correlation on the county scale in Hunan Province during this period. Local spatial autocorrelation indicated that the hot spots were mainly concentrated in the north of central Hunan, the east of central Hunan and the west of Hunan. Spatial-temporal scanning analysis revealed the first class clusters (RR = 6.65, P< 0.001) covering 34 counties in northern and central Hunan, mainly distributed in Yueyang City, Changsha City, Zhuzhou City, Yiyang City and Xiangtan City from May 2018 to June, and the second class clusters (RR = 3.02, P < 0.001) covering 40 counties in western Hunan and central and southwest Hunan from April 2016 to June 2016. Conclusion HFMD incidence exhibits seasonal and regional characteristics in Hunan Province. The prevention and control of HFMD should be guided by combining the characteristics of spatial-temporal clustering.
