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.

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 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.

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.

Objective To establish an ultra-high liquid chromatography(UPLC)characteristic spectrum of Rheum tanguticum Maxim.ex Balf.water decoction and conduct chemical pattern recognition analysis,and to identify the medicinal materials of different origins and different processed products.Methods:UPLC was adopted to establish the characteristic spectra of 15 batches of Rheum tanguticum Maxim.ex Balf.Cluster analysis combined with principal component analysis was used to analyze their quality.Rhei Radix et Rhizoma from different origins and different processed products of Rheum tanguticum Maxim.ex Balf.were identified.Results:The characteristic spectrum of Rheum tanguticum Maxim.ex Balf.water decoction was established,18 common peaks were identi-fied,and 15 batches of Rheum tanguticum Maxim.ex Balf.were divided into 2 categories according to their origins by cluster analysis.The similarity between 15 batches of samples from different origins and the control spectrum was greater than 0.900.According to OPLS-DA analysis,a total of 6 markers(rhein-8-O-β-D-glu-cosid,resveratrol-4'-O-β-D-(6''-O-D-gallyl)glucopyranside,isolindleyin,rhein,epicatechin-3-O-D-gallate,and catechin)affecting the quality of Rheum tanguticum Maxim.ex Balf.water decoction samples were found.Rhei Radix et Rhizoma from different origins and different processed products of Rheum tanguticum Maxim.ex Balf.can be effectively distinguished.Conclusion:The established characteristic spectrum method is easy to operate and has good repeatability.It can be used for the quality control of Rheum tanguticum Maxim.ex Balf.water decoction,and can provide reference for the formulation of quality standard of formula granules of Rhei Radix et Rhizoma.

Traumatic supraorbital fissure syndrome (TSOFS) is a symptom complex caused by nerve entrapment in the supraorbital fissure after skull base trauma. If the compressed cranial nerve in the supraorbital fissure is not decompressed surgically, ptosis, diplopia and eye movement disorder may exist for a long time and seriously affect the patients′ quality of life. Since its overall incidence is not high, it is not familiarized with the majority of neurosurgeons and some TSOFS may be complicated with skull base vascular injury. If the supraorbital fissure surgery is performed without treatment of vascular injury, it may cause massive hemorrhage, and disability and even life-threatening in severe cases. At present, there is no consensus or guideline on the diagnosis and treatment of TSOFS that can be referred to both domestically and internationally. To improve the understanding of TSOFS among clinical physicians and establish standardized diagnosis and treatment plans, the Skull Base Trauma Group of the Neurorepair Professional Committee of the Chinese Medical Doctor Association, Neurotrauma Group of the Neurosurgery Branch of the Chinese Medical Association, Neurotrauma Group of the Traumatology Branch of the Chinese Medical Association, and Editorial Committee of Chinese Journal of Trauma organized relevant experts to formulate Chinese expert consensus on the diagnosis and treatment of traumatic supraorbital fissure syndrome ( version 2024) based on evidence of evidence-based medicine and clinical experience of diagnosis and treatment. This consensus puts forward 12 recommendations on the diagnosis, classification, treatment, efficacy evaluation and follow-up of TSOFS, aiming to provide references for neurosurgeons from hospitals of all levels to standardize the diagnosis and treatment of TSOFS.
