Turning to critical illness is a common stage of various diseases and injuries before death. Patients usually have complex health conditions, while the treatment process involves a wide range of content, along with high requirements for doctor′s professionalism and multi-specialty teamwork, as well as a great demand for time-sensitive treatments. However, this is not matched with critical care professionals and the current state of medical care in China. Telemedicine, which shortens the distance of medical professionals and the gap of disease diagnosis and treatments in various regions through electronic information, can effectively solve the current problem. Therefore, there is an urgent need to develop a standardized, high-quality visualization telemedicine round system .Therefore, experts have been organized to search domestic and foreign literature on telemedicine round for critically ill patients and to form this consensus based on clinical experiences so as to further improve the level of critical care treatments in regions.

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.

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 Study the kidney toxic effects caused by burning coal endemic arsenism in rats,application bench mark dose (BMD) method to investigate the bench mark dose of urinary arsenic (UAs)and the changes in bio markers of renal function.METHODS Wistar rats were fed for 90 d with arsenic 0,25,50,100 mg·kg -1 conta minated feed.Urinary arsenic,kidney arsenic and renal function indicators were determined,and routine pathological and fibrosis of kidney were exa mined.UAs as the exposure bio marker,Uβ2-MG,UNAG and UALB for the effect bio markers,application bench mark dose method to calculate the BMD and BMDL of UAs for each effect bio markers.RESULTS UAs,KAs, Uβ2-MG,UNAG,UALB levels of rats in arsenic 100 mg·kg -1 group were increased than normal group (P <0.05);In light microscope,the results of HE staining of rat kidney in all arsenic dose groups showed infla mmatory cell infiltration,renal tubular epithelial cell swelling,renal interstitial capillary dila-tion,congestion and other varying degrees pathological changes,and the results of masson staining showed varying degrees of tubulointerstitial fibrosis;UAs as the exposure bio marker,Uβ2-MG,UNAG, UALB for the effects of mark,the BMD and BMDL of UAs for Uβ2-MG,UNAG,UALB were calculated, the BMD values were 998.9,1213.5,1386.9 μg·g -1 Cr,the BMDL values were 660.5,803.6 and 909. 4 μg·g -1 Cr,respectively.CONCLUSION Burning coal arsenic pollution can cause kidney da mage in rats,mini mal change nephropathy may be the pri mary pathological in the coal arsenic conta mination of kidney da mage.The BMD and BMDL of UAs were 998.9,660.5 μg·g -1 Cr,the early changes of renal function of burning coal arsenism in rats;it is reco mmended to use the more sensitive bio markers Uβ2-MG to calculate the biological exposure li mits on renal injury caused by arsenic.

Near infrared spectroscopy ( NIRS) is capable of determining water contents in oils. However, too much moisture contents in the oils will scatter rather than absorb the NIRS. This may cause greater measurement error. For this reason, a nonionic surfactant (Span-80) was screened to make the water in the oils evenly dispersed into small droplets. The NIRS analysis was subsequently employed to build support vector regression ( SVR ) model of the water content. In this experiments, the upper limit of the water content determination was improved from the conventional 0. 1% to 1. 0% ( V/V) by the oil-water stabilization. Applying successive projection algorithm, 15 valid variables (2. 9% of the original ones) from 511 NIRS variables were selected. With the proposed SVR model, the measurement precision criteria for the validation dataset were root mean squares error percentage 2 . 93%, correlation coefficient 0 . 9944 , and relative percent derivation 9 . 4732%.

Intestinal microflora is an important part of the organ-ism, promoting digestion and absorption of nutrients, maintaining intestinal normal physiological function, regulating immune sys-tem. Intestinal microflora maintains steady state under normal conditions, but intestinal microbiota dysbiosis occurs when surrounding environment c hanges, such as age, diet, obesity and other metabolic diseases as well as antibiotics. Many recent studies have found intestinal flora could cause a variety of disea-ses, and colon cancer is closely related with intestinal microbiota dysbiosis. Some researches suggest improving the intestinal flora dysbiosis can reduce the incidence of colon cancer and inhibit the growth and the worsening of colon cancer. However, under-lying mechanisms remain unknown. So this article summarizes the research progress on the development of colon cancer and in-testinal microbiota dysbiosis, in order to provide reference for re-search on intestinal flora and colon cancer treatment.

Objective To investigate the clinical features of IgG4 related autoimmune pancreatitis (AIP). Methods Clinical data of 12 patients pathologically diagnosed as IgG4 related AIP in Department of Hepatopancreatobiliary Surgery, Sun Yat-sen Memorial Hospital of Sun Yat-sen University from January 2003 to December 2012 were retrospectively analyzed. The informed consents of all patients were obtained and the ethical committee approval was received. All the patients were males with a mean age of (54±13) years old. All were misdiagnosed as pancreatic head carcinoma and received pancreatoduodenectomy. Data of the clinical manifestations, laboratory, imaging and pathological examinations were collected. The patients were followed up after operations, the treatment and outcome were studied. Results The clinical manifestations of the 12 patients were abdominal pain (n=7), jaundice(n=7), emaciation(n=6) and no obvious symptom (n=1). Three cases were combined with diabetes, 1 case with chronic sialadenitis of submandibular gland. The patient's blood and urine amylase were normal. Blood gamma-glutamyl transpeptidase (GGT) increase was observed in 12 cases. Mild increase of carbohydrate antigen 19-9 (CA19-9) was observed in 9 cases. Cancer antigen (CA) 125 increase was observed in 3 cases, and carcinoembryonic antigen (CEA) increase in 2 cases. Through contrast-enhanced CT, partial pancreatic head enlargement was observed in 11 cases, in which 3 cases were observed combining with mild expansion of pancreatic duct. Through magnetic resonance imaging (MRI), sausage-like change of pancreas body was observed in 4 cases, peripancreatic sheath-like change in 5 cases. Through magnetic resonance cholangiopancreatography (MRCP), stenoses in the pancreatic duct of pancreatic head segment and distal common bile duct were observed including 4 cases of mild expansion in the distal pancreatic duct. Local invasion was not observed by imaging examinations. Lymphoplasmacytic sclerosing pancreatitis was determined by pathological examination. Positive expression of IgG4 was observed by immunohistochemistry. Twelve cases suffered from discontinuous abdominal pain after operations, in which 7 cases needed acesodyne. One case relieved after using prednisone. Conclusions Clinical manifestations of IgG4 related AIP are similar to pancreatic carcinoma and can be misdiagnosed as pancreatic carcinoma easily. The main clinical features are mild increase of blood CA19-9. Partial pancreatic head enlargement, pancreas body sausage-like change, peripancreatic sheath-like change, and no local invasion are observed by imaging examinations. Lymphoplasmacytic sclerosing pancreatitis is determined by pathological examination. Positive expression of IgG4 is observed by immunohistochemistry. Adrenocortical hormone treatment is effective.
