Background and Aims:Pancreatic cancer is a highly aggressive malignancy that imposes a significant disease burden both in China and globally.It not only substantially increases healthcare expenditures but also profoundly influences health policy decisions.This study aims to systematically assess the disease burden of pancreatic cancer in China and worldwide over the past 30 years and to analyze future trends using a prospective predictive model,providing a scientific basis for the development of effective prevention and control strategies.Methods:Data on incidence,prevalence,mortality,and disability-adjusted life years(DALY)of pancreatic cancer,stratified by sex and standardized for age,were extracted from the Global Burden of Disease(GBD)database for the period 1990-2021.The autoregressive integrated moving average(ARIMA)model was used to predict the disease burden trends of pancreatic cancer for the next 15 years.Results:The results showed that from 1990 to 2021,the incidence,prevalence,mortality,and DALY rates of pancreatic cancer exhibited an increasing trend in both China and worldwide.Males had significantly higher incidence and mortality rates than females,with a faster growth rate.The highest incidence and mortality rates were observed in economically developed regions such as North America and Europe,while lower rates were noted in less developed regions such as Africa and South Asia.However,with economic development and lifestyle changes,the pancreatic cancer burden in these low-incidence regions is also gradually increasing.Over time,the growth rate of pancreatic cancer incidence and mortality in China has surpassed the global average,and with an aging population,the disease burden is expected to rise further in the future.Conclusion:There are significant variations in the pancreatic cancer burden across genders and regions.Strengthening health education and early screening for high-risk populations,optimizing personalized treatment strategies,and increasing investment in basic research on pancreatic cancer are essential to mitigating the growing disease burden.This study provides crucial scientific evidence for the formulation of pancreatic cancer prevention and control strategies,contributing to improved patient outcomes and reduced socioeconomic burden.

Objective To explore the characteristics of patients with stagnation of liver-qi syndrome using brain functional imaging techniques.Methods10 patients with stagnation of liver-qi syndrome and 20 normal persons whom paired by sex and age were scanned with positron emission tomography(PET).Data analysis was carried out using SPM in MATLAB software.ResultsCompared with normal,some cerebral areas of the patients with stagnation of liver-qi syndrome showed glucose metabolism letdown(P<0.001),including right parietal lobe(postcentral gyrus,BA1/2),temporal lobe(middle temporal gyrus,BA37),frontal lobe(middle frontal gyrus,BA9/10)etc.,while some cerebral areas showed glucose metabolism heighten(P<0.001)including right frontal lobe(superior frontal gyrus,inferior fontal gyrus,BA22/28/44),right cingulated gyrus,double midbrain and cerebella,etc.ConclusionThe function of some cerebral areas can be changed undergoing stagnation of liver-qi syndrome.

Functional magnetic resonance imaging (fMRI) is an imaging method of function brain area by stimulate in magnetic resonance facility; it can exactitude reflect the nerve activity level of brain and confirm the function brain area in alive body; it is a new impersonality imagine method to evaluate the cognitive function of human. Cognitive function obstacle is a clinical syndrome of damaging cognitive function by manifold reasons and can be leaded by many diseases in clinic. Studying changed function brain area by fMRI can offer an impersonality and intuition imagine evidence to forepart prevent, diagnose and therapy of the diseases of cognitive function obstacle.

Electroencephalogram non-linear analysis is one of the methods to study brain electric signal complexity and the mutual connection of signals based on the non-linearity principle and method. It can provide condition such as the neural networks function, contact information, the changing trajectory cerebrum function activity. It can be used for nerve spirit disease studying, the depth anaesthetize monitor ,the sleep studies in modern medicine, it breaks the ice in traditional Chinese medicine just now. The application of electroencephalogram non-linear analysis has open up an exhibition further to cerebrum's research.

Objective To investigate the changes of non-linear dynamics characteristics of electroencephalogram(EEG) in patients with the stagnation of Liver-Qi syndrome.Methods 15 Liver-Qi stagnation syndrome patients and 15 normal persons were paired by sex and age.The data of EEG under three states(eyes closed,eyes opened,and mental arithmetic with eyes opened) were analyzed by the parameter of point-wise correlation dimension(PD2).Results PD2 of the stagnation of Liver-Qi syndrome group increased significantly compared with that of the healthy control group and always maintain high level.The difference of PD2 between two groups was gradually reduced along with the increase of stimulated condition.Conclusion Non-linear dynamic analysis is more appropriate for the study of mental functions changes of stagnation of Liver-Qi syndrome and can be used to investigate the brain mechanism of the stagnation of Liver-Qi syndrome.

Objective:To explore the effect of Naoshuning on the protein expression of Matrix metalloproteinases(MMPs) in experimental injuried brain tissue of rats. Methods:Immunohistochemistry was used to determine the changes of protein expression of MMPs. Brain tissue water content,permeability and ultramicrostructure of blood-brain barrier(BBB) were also observed. Results:Compared with the sham group,the brain tissue water and EB content of injured side and the level of MMP-2 and MMP-9 protein expression in brain tissue around contusion in model group increased obviously(all P

ObjectiveTo observe the protective effects of Chinese medicine Naoshuning on neurological deficits following traumatic brain injury (TBI) in rats.MethodsCerebral contusion was produced by dropping weight,the beam-walking task was employed to observe neurological functional changes,water content in the brain tissue and neuropathological changes were also evaluated.ResultsWithin one week the ability to process in beam-walking task was significantly lessened,the outcome of beam-walking task of Naoshuning group was significantly better than that of the model group.Water content in the brain tissue and neuropathological changes were also alleviated in Naoshuning group compared with that in model group.ConclusionEarly alleviating brain edema,protecting brain tissue may be one of the mechanism of Chinese medicine to ameliorate the behavior deficits following TBI in rats.

ObjectiveTo investigate the dynamic change of cerebral aquaporin 4 (AQP4) expression level during traumatic brain injury (TBI) in rats and the relationship between AQP4 expression and traumatic brain injury and edema. MethodsThe experimental TBI model was established by bumpiness of free falling body according to Feeney's. The changes of brain water content (BWC) and permeability of blood-brain barrier (BBB) were measured by the methods of wet and dry weight and Evans blue fluorometry. Immunohistochemistry was used to determine the change of expression of AQP4 during different periods after TBI. Results6 h after TBI, water content of brain tissue and EB content in the contusion side significantly increased, and the protein expression of AQP4 in contusion marginal region began to increase. They reached summit 24 h after operation and did not come back normal level 5 d after operation. There was significantly positive correlation between protein expression of AQP4 and change of EB content (r=0.957486,P<0.05). ConclusionThe dynamic change of cerebral AQP4 expression level closely related to the destruction of BBB and the formation of cerebral edema during traumatic brain injury.
