Hepatic echinococcosis is a chronic parasitic disease, which is caused by the larvae of Echinococcus multilocularis. It has a high risk of disability and mortality, which is also known as "parasite cancer". In clinical practice, hepatic echinococcosis can be divided into hepatic alveolar echinococcosis and hepatic cystic echinococcosis. Hepatic echinococcosis is widely prevalent worldwide. It mainly occurs in the populations residing agricultural and pastoral areas in western China, posing significant threats to the quality of life of local residents. At present, surgery is the main treatment for hepatic echinococcosis in clinical settings. With rapid development of surgical diagnosis and treatment technology and deepening understanding of hepatic echinococcosis, diagnosis and treatment regimens have also been constantly improved. In this article, research progresses on the diagnosis and treatment of hepatic alveolar echinococcosis were reviewed, aiming to provide reference for clinicians, deliver early diagnosis and treatment, mitigate adverse effects of this disease upon patients and improve clinical prognosis.

ObjectiveTo investigate the effect and mechanism of echinacoside （ECH） in improving liver injury in rats with acute pancreatitis by establishing a rat model of acute pancreatitis and liver injury. MethodsA total of 24 Sprague-Dawley rats were randomly divided into blank group （Con group）， control group （Con+ECH group）， acute pancreatitis group （AP group）， and acute pancreatitis+ECH intervention （AP+ECH group）. The rats were given intraperitoneal injection of 10 mg/kg ECH on day 7 before the establishment of the model of acute pancreatitis； at 24 hours after the last administration of cerulein， blood samples were collected via the abdominal aorta， and serum was separated for biochemical analysis including alanine aminotransferase （ALT）， aspartate aminotransferase （AST）， lactate dehydrogenase （LDH）， gamma-glutamyl transpeptidase （GGT）， alkaline phosphatase （ALP）， albumin （Alb）， total bilirubin （TBil）， cholinesterase， blood amylase （Amy）， and lipase （LPS）. HE staining was used to observe the histopathological changes of the pancreas and the liver； transmission electron microscopy （TEM） was used to observe the microstructural changes of pancreas and liver tissue； ELISA was used to measure the levels of interleukin-1β （IL-1β）， interleukin-16 （IL-6）， tumor necrosis factor-α （TNF-α）， and interleukin-10 （IL-10） in liver tissue homogenate； immunohistochemistry was used to measure the levels of TNF-α and p-p65 NF-κB in pancreas and liver tissue； Western blot was used to measure the expression levels of NF-κB pathway proteins in liver tissue. A one-way analysis of variance was used for comparison of continuous data between multiple groups， and the SNK test or the Dunnett’s T3 method was used for further comparison between two groups. ResultsCompared with the Con group， the AP group had significant increases in ALT， AST， GGT， LDH， ALP， TBil， Amy， and LPS （all P<0.01）， as well as significant increases in the levels of IL-1β， IL-6， IL-10， and TNF-α in liver tissue homogenate （all P<0.01）. ECH intervention reduced the levels of ALT， AST， GGT， LDH， ALP， TBil， AMY， and LPS and inhibited the secretion of IL-1β， IL-6， and TNF-α in rats with acute pancreatitis. HE staining showed that ECH intervention alleviated the vacuolar degeneration of acinar cells， inflammatory cell infiltration in pancreatic tissue， and the necrosis of hepatocytes compared with the AP group. TEM showed that compared with the AP group， there was a reduction in the degree of mitochondrial swelling in liver and pancreatic cells after ECH intervention. ECH intervention partially reversed the elevated expression levels of p-p65 NF-κB and TNF-α in liver and pancreatic tissue. In addition， the expression levels of MyD88， p-IκBα， p-IKKα， and p-p65 were upregulated in liver tissue of rats with acute pancreatitis， which could be partially reversed after ECH intervention. ConclusionEchinacoside can alleviate liver and pancreatic injury induced by acute pancreatitis by inhibiting the TLR4/MyD88/NF-κB pathway.

Objective To investigate the changes of cortical thickness in patients with insomnia disorder(ID).Methods High-resolution MRI data were collected from 32 ID patients(ID group)and 30 healthy controls(HC)(HC group).The cortical thickness of both groups were analyzed using statistical parametric mapping 12(SPM12)software,while considering age,gender,and educational level as covariates.The cortical thickness in brain regions showed statistically significant differences was extracted for Pearson's correla-tion analyses with sleep and mood-related scales.Results Compared with the HC group,the ID group exhibited significantly decreased cortical thickness in brain regions such as the left insula,fusiform gyrus,orbitofrontal lobe,superior temporal gyrus,middle temporal gyrus,lateral occipital lobe and right caudal anterior cingulate gyrus[P＜0.05,family-wise error(FWE)correction].Furthermore,reduced cortical thickness of the cingulate gyrus was negatively correlated with the Pittsburgh sleep quality index(PSQI)score(r=-0.437,P=0.012).Conclusion The cortical thickness of several brain regions associated with sleep and mood are significantly reduced in patients with ID,providing potential neuroimaging evidence for understanding the pathophysiological mechanism of ID.

Cardiovascular surgery is still the preferred treatment for some congenital or acquired cardiovascular diseases.With the aging of China's population and the prevalence of unhealthy lifestyles brought about by the improvement of living standards,the burden of cardiovascular diseases is still steadily increasing and the volume of cardiovascular surgery continues to be at a high level,which puts forward a new demand for the prevention and treatment strategy of cardiovascular diseases and the allocation of medical resources.Cardiovascular surgery has many perioperative complications and high risk of mortality,a scientific surgical complexity scoring system can help clinicians fully assess the difficulty of surgery,stratify the risk of patient surgery,and formulate targeted and personalized diagnosis and treatment plans;meanwhile,it can help the health management department accurately grasp the overall diagnosis and treatment level of China's cardiovascular surgery,monitor the quality of medical care and provide a reference for the formulation and implementation of relevant medical policies.In this study,we systematically review the current status of evidence-based research on different cardiovascular surgical complexity assessment systems and summarize the application of machine learning in cardiovascular surgical assessment,with a view to contributing to the establishment of a cardiovascular surgical complexity assessment system applicable to the Chinese population.

ResultsA total of 285 literatures were finally included, involving 1 279 authors, out of whom 111 published 97.19% of the total number of articles. The main keywords included spinal cord injury, spinal fractures, neurological function, thoracolumbar fractures and spinal tuberculosis, which classified in seven clusters, and the topics of spinal cord injury, efficacy, spinal fractures, quality of life and prognosis were the hotspots in the field. With manual searching, the main topic was spinal cord injury; the main object was traumatic spinal cord injury; the main purpose was to evaluate the surgical efficacy; the research institutions were mostly the comprehensive hospitals or specialized hospitals focusing on orthopedics (spinal surgery); the clinical departments that used ISNCSCI the most were orthopedics (including spinal surgery) and rehabilitation medicine, and nursing teams were paying more attention to ISNCSCI; the most commonly used versions of ISNCSCI were 2011 (7th edition) and 2000 (6th edition), however, for a large number of articles, the versions were not clear or earlier than 2000. ConclusionThe application of ISNCSCI in China should be improved in the standardization.

【Objective】 To investigate cortical thickness changes in the face-head region of the primary motor cortex (PMC) and its effect on survival in amyotrophy lateral sclerosis (ALS) patients. 【Methods】 A retrospective analysis was performed on 105 ALS patients who underwent head MRI scan at the same time. The A4hf (face-head) region of PMC was used as the region of interest (ROI). According to clinical symptoms, patients were divided into two groups: bulbar involvement and non-bulbar involvement. The differences of clinical features and cortical thickness in ROI were analyzed. According to the symptoms of bulbar palsy, physical examination of nervous system and EMG of tongue muscle, the patients with bulbar palsy were divided into lower motor neuron (LMN), upper motor neuron (UMN) and LMN+UMN groups. The differences of bulbar subgroup score and ROI of cortical thickness were analyzed. Age at onset, body mass index, delayed time of diagnosis, bulbar subgroup score, and ROI cortical thickness were included in survival analysis. 【Results】 ① The ROI cortical thickness was significantly lower in bulbar involvement group than non-bulbar involvement group (-0.198±0.87 vs. 0.235±0.95, P=0.017). ② There were no significant differences in the bulbar subgroup scores or cortical thickness of ROI between LMN, UMN and LMN+UMN groups (P>0.05). ③ Survival analysis showed age of onset (HR=3.296, 95% CI:1.63-6.664, P=0.001), delayed time of diagnosis (HR=0.361, 95% CI:0.184-0.705, P=0.003), bulbar subgroup score (HR 0.389, 95% CI:0.174-0.868, P=0.021), and ZRE_ROI cortical thickness (HR=2.309, 95% CI:1.046-5.096, P=0.038) were independent influencing factors of ALS survival. 【Conclusion】 Cortical thickness in A4hf (face-head) region can more objectively reflect UMN signs of region bulbar. In addition to age of onset and delayed time of diagnosis, bulbar subgroup score and cortical thickness of face-head region are also independent influencing factors, and cortical thinning in face-head region is a protective factor for survival of ALS patients.

【Objective】 The involvement of upper motor neuron (UMN) degeneration is crucial to the diagnosis of amyotrophic lateral sclerosis (ALS). This study aimed to determine objective and sensitive UMN degeneration markers for an accurate and early diagnosis. 【Methods】 A total of 108 ALS patients and 90 age- and gender-matched control subjects were recruited from ALS Clinic of The First Affiliated Hospital of Xi’an Jiaotong University. The motor homunculus cortex thickness data in MRI were collected from all the participants. The clinical characteristics and UMN clinical examination of bulbar, cervical, thoracic and lumbosacral regions were collected from the ALS patients. 【Results】 Cortical thickness was significantly thinner in the ALS group than in the control group in bilateral head-face-bulbar and upper-limb areas (P<0.05). The cortical thickness of the global UMN positive group was significantly thinner than that of control groups in bilateral head-face-bulbar and upper-limb areas (P<0.05). The cortical thickness of the UMN positive group in the corresponding region was significantly thinner than that of control groups in bilateral head-face-bulbar and upper-limb areas (P<0.05). 【Conclusion】 The thinning of the motor homunculus cortex can be used as an objective marker of UMN involvement in ALS patients in clinical practice.

Objective:To evaluate the efficacy of percutaneous vertebroplasty (PVP) by percutaneous bi-level bilateral puncture in the treatment of type ⅡA acute symptomatic osteoporotic thoracolumbar fracture (ASOTLF) with dense bone bands.Methods:From March 2017 to March 2018, 65 patients (65 vertebrae) with type ⅡA ASOTLF with dense bone bands were treated at Department of Orthopaedic Trauma, Qingdao Central Hospital. They were 25 males and 40 females, with an age of (71.6±8.4) years. The time from injury to operation was (3.5±0.7) d. They were divided into 2 groups according to different treatments. In the observation group of 31 cases (31 vertebrae), PVP was conducted by percutaneous bi-level bilateral puncture; in the control group of 34 cases (34 vertebrae), PVP was conducted by percutaneous single-level bilateral puncture. The 2 groups were compared in terms of operation time, volume of polymethyl methacrylate injected, incidence of bone cement leakage, incidence of vertebral refracture, diffusive distribution of bone cement in the vertebral body, and visual analogue scale (VAS) and Oswestry dysfunction index (ODI) at postoperative 1 day and 6 months.Results:There was no significant difference in the preoperative general data between the 2 groups, showing comparability ( P>0.05). Operations were completed uneventfully in all the 65 patients. All the 65 patients were followed up for (8.2±1.2) months. There was no significant difference between the 2 groups in operation time, incidence of bone cement leakage or incidence of vertebral refracture for each vertebral body injured ( P>0.05). The volume of polymethyl methacrylate injected [(6.64±0.93) mL] and the excellent and good rate of diffusive distribution of bone cement in the vertebral body [87.1% (27/31)] in the observation group were significantly larger than those in the control group [(4.36±0.79) mL and 64.7% (22/34)] ( P<0.05). The VAS scores at postoperative 1 day and 6 months [2 (1, 2) and 1 (1, 2)] and ODIs at postoperative 1 day and 6 months (23.7%±1.6% and 18.8%±1.4%) in the observation group were significantly lower than those in the control group [2 (2, 3) and 2 (2, 2); 26.9%±4.2% and 22.1%±3.3%] ( P<0.05). The VAS scores and ODIs at postoperative 1 day and 6 months in all patients were significantly lower than those before operation ( P<0.05). Compression symptoms of the spinal cord and nerve root were observed in none of the patients. Conclusion:In the treatment of type ⅡA ASOTLF with dense bone bands, PVP by percutaneous bi-level bilateral puncture is more effective than the traditional PVP by percutaneous single-level bilateral puncture, and will not increase bone cement leakage or vertebral refracture.
