Objective:To explore the risk factors of delayed traumatic intracranial hematoma (DTICH)followed by unilateral large decompressive craniectomy (LDC)and its influence in the prognosis of the severe traumatic brain injury (sTBI)patients,and to improve the successful rate of the rescue.Methods:The clinical data of 130 sTBI patients underwent unilateral LDC were retrospectively analyzed.The patients were divided into DTICH group (n=42)and non-DTICH group (n=88)according to whether the DTICH occurred after operation.The risk factors of DTICH and its influence were contrastively analyzed.Results:The analysis results of the clinical data of patients in two groups showed that preoperative GCS,time from trauma to operation,skull fracture,midline shift > 1 cm, basal cistern disappear,activated partial prothrombin time (APTT),fibrinogen (FIB),and thrombin time (TT) were significantly correlated with the appearance of DTICH (P<0.05).Multivariable Logistic regression analysis showed that the time from trauma to operation, skull fracture, basal cistern disappearing and FIB were the independent risk factors of DTICH (P<0.05).The analysis results of GOS 3 months after operation of the patients in two groups showed that the prognosis of the patients in DTICH group was significantly worse than that in non-DTICH group (P<0.01 ).Conclusion:For those patients who accompanied with shorter time from trauma to operation,skull fracture,basal cistern disappearing and FIB decrease,the appearance of DTICH should be paid attention.DTICH can affect the prognosis of patients;prevention and early diagnosis are crucial to improve the prognosis of patients.

Purpose To analyze the perfusion differences of different pancreatic diseases using the low-dose whole organ dynamic volume CT perfusion imaging, and to provide the evidence for the clinical application. Materials and Methods Twenty-eight patients suspected as pancreatic disease were applied by 640 layer volume CT perfusion imaging for the pancreas. Data were collected at the same time of bolus injection of contrast agent, then were analyzed by spatial alignment and perfusion calculation using the perfusion software. The time-density curve, blood perfusion flow diagram and tissue artery blood flow were obtained using the maximum slope method. Results Normal pancreatic tissue (n=9) blood flow was (117.04±12.05) ml/(min?100 ml), pancreatitis organizations (6 cases with acute pancreatitis and 3 cases with chronic pancreatitis) (118.67±37.18) ml/(min?100 ml), pancreatic carcinoma tissue (n=10) was (67.16±18.94) ml/(min?100 ml). There was significant difference among three groups (F=8.59, P<0.001);the difference was demonstrated in pancreatic cancer vs. normal pancreas and pancreatic cancer vs. pancreatitis group (q=3.70, P<0.05), which could be clearly demonstrated by blood perfusion flow diagram. The difference was not statistically revealed pancreatitis and normal pancreas group (q=2.91, P>0.05). The total dose of X-rays in the whole scanning process was 21.5-23.9 mSv. Conclusion Low-dose whole pancreas organ CT perfusion scan can quantitatively analyze the hemodynamic changes in pancreatic disease, which be of great value for evaluating changes in microcirculation during the treatment of pancreatic cancer.

Objective To explore the influence of early system rehabilitation treatment on severe brain injury. Methods 120 inpatients with severe brain injury were divided into 4 groups according to the disease course. Group 1: <1 month; Group 2: 1~3 months, Group 3: 3~6 months; Group 4: 6~12 months. Fugl-Meyer Assessment (FMA) and Modified Barthel Index (MBI) were assessed before and 2 months after treatment. Results All groups were with better effects after treatment than before (P<0.05), early system rehabilitation had better effects especially for Group 1 (P<0.05). Conclusion Early rehabilitation treatment can facilitate the recovery of patients with severe brain injury

Objective To investigate the expression changes of astrocytic syntrophin in hippocampus from human mesial temporal lobe epilepsy (MTLE). Methods From April, 2015 to July, 2016, 17 cases of hippocampus, collected from temporal lobectomy, were divided into MTLE group (n=13) and non-MTLE group (n=4) according to hematoxylin and eosin staining, glial fibrillary acidic protein and neuronal nu-clei immunohistochemical staining. Immunofluorescence double labeling and immunofluorescence histochemistry were used to observe the expression of syntrophin. Results The proliferation of astrocytes increased and neurons reduced in the hippocampus of MTLE group. Syntro-phin was found in the membrane and foot processes of astrocyte, that was enriched along perivascular astrocyte end-feet domain in non-MTLE group, but lost in MTLE group. While the whole expression of syntrophin was more in MTLE group than in non-MTLE group (t=5.421, P<0.001). Conclusion The distribution of syntrophin in hippocampus astrocytes may be related to the development of MTLE.

In recent years, the incidence of hepatocellular carcinoma (HCC) has risen year by year, leading to a high mortality rate. At present, surgical treatment is the major cure for HCC, and in general, HCC is diagnosed at late stages. Due to the heterogeneity of HCC and different sensitivities to drugs, the treatment efficacy of advanced HCC is poor. In this paper, we retrospectively analyzed the prog-ress of HCC treatments and reviewed important progression, which provides new view for the clinical improvement of the total surviv-al of patients with HCC.

ObjectiveTo understand the current research status, research hotspots and development trends of constraint-induced movement therapy (CIMT) in the field of rehabilitation. MethodsThe relevant articles of CIMT in rehabilitation from January, 2000 to October, 2022 in CNKI and Web of Science were retrieved. The authors, institutions, countries, keywords and burst words were extracted with CiteSpace 6.1.R3 to draw knowledge mapping. ResultsA total of 1 165 articles were included, 359 articles in Chinese and 806 in English. The trend of annual publications was generally consistent, and after a period of rapid growth, the current annual publications showed a fluctuating trend. There was more cooperation among the institutions in English articles, with geographical limitation. The institutions in Chinese articles had the problem of insufficient cooperation. The researches mainly focused on the application of CIMT in different diseases, the improvement of motor function by CIMT, the application of CIMT in combination with other therapies, and the study of the related mechanisms of CIMT. In recent years, Chinese burst keywords included modified constraint-induced movement therapy, stroke hemiparesis, clinical efficacy and repetitive transcranial magnetic stimulation; English burst keywords included transcranial direct current stimulation, non-invasive brain stimulation, and unilateral cerebral palsy. ConclusionResearch on CIMT in the field of rehabilitation is in a period of steady development, and CIMT combined with non-invasive brain stimulation is likely to be a hotspot in future research.

People as third-party observers, without direct self-interest, may punish norm violators to maintain social norms. However, third-party judgment and the follow-up punishment might be susceptible to the way we frame (i.e., verbally describe) a norm violation. We conducted a behavioral and a neuroimaging experiment to investigate the above phenomenon, which we call the "third-party framing effect". In these experiments, participants observed an anonymous perpetrator deciding whether to keep her/his economic benefit while exposing a victim to a risk of physical pain (described as "harming others" in one condition and "not helping others" in the other condition), then they had a chance to punish that perpetrator at their own cost. Our results showed that the participants were more willing to execute third-party punishment under the harm frame compared to the help frame, manifesting a framing effect. Self-reported anger toward perpetrators mediated the relationship between empathy toward victims and the framing effect. Meanwhile, activation of the insula mediated the relationship between mid-cingulate cortex activation and the framing effect; the functional connectivity between these regions significantly predicted the size of the framing effect. These findings shed light on the psychological and neural mechanisms of the third-party framing effect.

Coronary restenosis is an important cause of poor long-term prognosis in patients with coronary heart disease. Here, we show that lysine methyltransferase SMYD2 expression in the nucleus is significantly elevated in serum- and PDGF-BB-induced vascular smooth muscle cells (VSMCs), and in tissues of carotid artery injury-induced neointimal hyperplasia. Smyd2 overexpression in VSMCs (Smyd2-vTg) facilitates, but treatment with its specific inhibitor LLY-507 or SMYD2 knockdown significantly inhibits VSMC phenotypic switching and carotid artery injury-induced neointima formation in mice. Transcriptome sequencing revealed that SMYD2 knockdown represses the expression of serum response factor (SRF) target genes and that SRF overexpression largely reverses the inhibitory effect of SMYD2 knockdown on VSMC proliferation. HDAC3 directly interacts with and deacetylates SRF, which enhances SRF transcriptional activity in VSMCs. Moreover, SMYD2 promotes HDAC3 expression via tri-methylation of H3K36 at its promoter. RGFP966, a specific inhibitor of HDAC3, not only counteracts the pro-proliferation effect of SMYD2 overexpression on VSMCs, but also inhibits carotid artery injury-induced neointima formation in mice. HDAC3 partially abolishes the inhibitory effect of SMYD2 knockdown on VSMC proliferation in a deacetylase activity-dependent manner. Our results reveal that the SMYD2-HDAC3-SRF axis constitutes a novel and critical epigenetic mechanism that regulates VSMC phenotypic switching and neointimal hyperplasia.
