To explore the roles of astrocytes in the epileptogenesis, astrocytes and neurons were isolated, purified and cultured in vitro from cerebral cortex of rats. The astrocytes were activated by ciliary neurotrophic factor (CNTF) and astrocytic conditioned medium (ACM) was collected to treat neurons for 4, 8 and 12 h. By using Western blot, the expression of calmodulin dependent protein kinase Ⅱ (CaMK Ⅱ), inducible nitric oxide synthase (iNOS) and adenylate cyclase (AC) was detected in neurons. The results showed that the expression of CaMK Ⅱ, iNOS and AC was increased significantly in the neurons treated with ACM from 4 h to 12 h (P＜0.05), and that of iNOS and AC peaked at 8 h and 12 h respectively. It was suggested that there might be some epileptogenic factors in the ACM and such signal pathways as NOS-NO-cGMP, Ca2+/CaM-CaMK Ⅱ and AC-cAMP-PKA might take part in the signal transduction of epileptogenesis.

Due to the difference of cultural background, the psychological, social and spiritual needs of dying people are very different, so there are great differences in the care and nursing concept of dying people in different countries and nationalities. In order to construct the modern hospice care, we should actively learn from the western experience, but more important is to dig the local ideological resources from the traditional culture, build a set of caring care theory and practice rooted in China and originated from the concept of a good end of Chinese traditional culture, with the characteristics of the times and the cultural confidence of the Chinese nation, serving the Chinese people, and with Chinese characteristics.

Objective: To establish primary immune thrombocytopenia (ITP) animal model induced by anti-platelet membrane glycoprotein GPⅠbα antibodies AN51 and R300. Methods: Twenty guinea pigs (6-8 week) were divided into 4 groups. Five guinea pigs in each group were intravenously injected with different doses of AN51 (0.05, 0.1, 0.2 μg/g) and 0.2 μg/g IgG as control. The whole blood was collected from inner angular venous plexus. Platelets number was determined by an automated cell counter and Swiss-Jim method. Then, the similar protocol was used to establish ITP nude mice model by intraperitoneal injection of different concentrations of anti-platelet GPⅠbα antibody R300, respectively. Results: ①Five minutes after intravenous injection of AN51 at 0.05, 0.1 and 0.2 μg/g, the platelet counts of guinea pigs reduced about 0-5%, 50%-60% and 70%-80% compared to the control group, respectively. The difference was statistically significant (P<0.01) . ②Six hours after intraperitoneal injection of R300 at 0.05, 0.1, 0.2 μg/g, the platelet counts of nude mice decreased about 20%-30%, 60%-70% and 80%-90% compared to the control group, respectively. The difference was statistically significant (P<0.01) . The nude mice, injected 0.2 μg/g R300 once a day for 2 weeks, showed typical ITP clinical manifestations including large number of petechiaes or ecchymoses on limbs, head and abdomen. Conclusion AN51 at 0.2 μg/g and R300 at 0.2 μg/g could establish stable ITP model in guinea pigs and nude mice respectively.

Objective:To construct a nomogram for predicting unfavorable prognosis at 6 months after moderate and severe traumatic brain injury (msTBI) and validate its predictive effectiveness.Methods:A retrospective cohort study was conducted to analyze the clinical data of 387 patients with msTBI who were admitted to 904th Hospital of the Joint Logistic Support Force of PLA from January 2020 to December 2022, including 265 males and 122 females, aged 6-97 years [58(47, 68)years]. According to the Glasgow outcome scale (GOS) score at 6 months after injury, the patients were divided into favorable prognosis group (GOS 4-5 points, n=201) and unfavorable prognosis group (GOS 1-3 points, n=186). The clinical characteristics, imaging manifestations, and laboratory test results of the two groups on admission were recorded. Univariate analysis was applied to evaluate the correlation between the aforementioned indicators and the unfavorable prognosis of the msTBI patients at 6 months after injury. Receiver operating characteristic (ROC) curves of single variable and the correlation heatmap among continuous variables were plotted. Lasso regression was used to select variables and multivariate Logistic regression analysis was used to determine independent predictive factors so as to construct Logistic regression equation and plot the nomogram. The internal verification was carried out by means of random and non-random split of data. In random split, the data were divided randomly with a ratio of 6∶4 into training group ( n=232) and verification group ( n=155). In non-random split, the patients admitted from January 2020 to December 2021 were assigned to the training group ( n=260), while those admitted from January 2022 to December 2022 to the verification group ( n=127). Area under the curve (AUC) was used to evaluate the predictive ability of the model in the training group and verification group, calibration curve and Hosmer-Lemeshow (H-L) test to evaluate its goodness of fit, and decision curve analysis (DCA) to evaluate its clinical applicability. The influence of inclusion of neutrophil-to-lymphocyte ratio (NLR) model on the warning effectiveness of poor prognosis was analyzed in comparison with the model without inclusion of NLR. Results:Univariate analysis showed that there was a certain correlation between age, length of hospital stay, Glasgow coma scale (GCS), American Society of Anesthesiologists Physical Status (ASA-PS) classification, Injury severity score (ISS), prehospital tracheal intubation, hypotension, hypoxia, pupillary responsiveness, midline shift, basilar cisterna status, traumatic subarachnoid hemorrhage (tSAH), D-Dimer, prothrombin time activity (PTA), glucose, hemoglobin, K +, Cl -, Ca 2+, HCO -, creatinine, albumin, lactic acid, platelet, lymphocyte, systemic immune-inflammation index (SII), NLR, lymphocyte-to-monocyte ratio (LMR) and unfavorable prognosis of msTBI patients at 6 months after injury ( P<0.05 or 0.01). The ROC curve of single variable showed that GCS (AUC=0.82), ISS (AUC=0.81), pupillary responsiveness (AUC=0.76), basal cistern status (AUC=0.73) and NLR (AUC=0.73) had good predictive validity. The results of the correlation heatmap showed that there was a significant correlation and collinearity among the continuous variables, while no collinearity was found between ISS and NLR. Fourteen potential predictors selected by Lasso regression were included in multivariate Logistic regression analysis and its results showed that age ( OR=0.86, 95% CI 1.38, 5.19), GCS 6-8 points ( OR=3.13, 95% CI 1.06, 9.27), GCS 3-5 points ( OR=12.36, 95% CI 2.81, 54.27), ISS ( OR=3.68, 95% CI 1.38, 9.80), pupillary responsiveness ( OR=2.45, 95% CI 0.85, 7.07), and NLR ( OR=2.62, 95% CI 1.52, 4.51) were identified as the independent risk factors for unfavorable prognosis of msTBI patients at 6 months after injury ( P<0.05 or 0.01). The multivariate Logistic regression equation was Logit [P/(1-P)]=0.066×"age"+ 1.474×"GCS 6-8"+2.357×"GCS 3-5"+0.066×"ISS"+0.965×"absence of pupillary light reflex"+0.194×"NLR"-10.704. In the internal verification of random split of data, the AUC value of the model was 0.93 (95% CI 0.89, 0.96) in the training group and 0.93 (95% CI 0.89, 0.97) in the verification group. In the internal verification of non-random split, the AUC value was 0.94 (95% CI 0.91, 0.97) in the training group and 0.93 (95% CI 0.89, 0.97) in the verification group. The calibration curve and H-L test showed that the model had good calibration ability ( P>0.5). The results of DCA showed that the application of the nomogram would increase the net benefit of the patients (risk threshold probability of 0.0-0.8). Compared with the conventional model (AUC=0.90), inclusion of NLR model (AUC=0.93) enhanced the warning effectiveness. Conclusions:Age, GCS, ISS, pupillary responsiveness and NLR are independent risk factors affecting unfavorable prognosis in msTBI patients at 6 months after injury, based on which the nomogram constructed can better predict the clinical outcome of msTBI patients.

ObjectiveTo explore the prevalence difference between northwest dryness syndrome and blood stasis syndrome of coronary heart disease （CAD） and their correlations with major adverse cardiovascular events （MACE）. MethodsThe medical records including general information and risk factors for vascular diseases （gender， age， smoking history， diabetes history， hypertension history， chronic kidney disease history and body mass index）， laboratory indicators （fasting blood glucose， triglyceride， high density lipoprotein cholesterol， etc.） of 499 CAD patients in the Department of Cardiology of the Affiliated Hospital of Traditional Chinese Medicine of Xinjiang Medical University from November 1st， 2015 to September 30th，2020 were collected， and whether they suffered from northwest dryness syndrome or blood stasis syndrome was judged. The incidence of MACE was followed up for one year. The differences of cardiovascular risk factors between the northwest dryness syndrome and blood stasis syndrome of CAD were compared， and the correlation with MACE was analyzed. ResultsAmong the 499 CAD patients， there were 128 cases （25.65%） of simple blood stasis syndrome， 33 cases （6.61%） of simple northwest dryness syndrome， 209 cases （41.88%） of northwest dryness syndrome plus blood stasis syndrome， and 129 （25.85%） cases of not blood statis syndrom either northwest dryness syndrome. Univariate regression analysis showed that smoking history， diabetes history， fasting blood glucose abnormality， triglyceride abnormality， and high density lipoprotein cholesterol abnormality were positively correlated with northwest dryness syndrome in CAD patients （OR＞1， P＜0.05）， while smoking history， abnormal triglyceride and abnormal high density lipoprotein cholesterol were positively correlated with blood stasis syndrome in CAD patients （OR＞1， P＜0.05）. Multivariate regression analysis showed that the history of diabetes， abnormal triglyceride and abnormal high density lipoprotein cholesterol were positively correlated with northwest dryness syndrome of CAD （P＜0.05）. Smoking history， abnormal triglycerides and abnormal high density lipoprotein cholesterol were positively correlated with blood stasis syndrome （P＜0.05）. Association rule analysis showed that the confidence of CAD patients with northwest dryness syndrome complicated with blood stasis syndrome was 86.36%， and that of patients with blood stasis syndrome complicated with northwest dryness syndrome was 62.02%. Among the 499 patients， 96 had MACE in one year， accounting for 19.24% of the total. Logistics regression analysis showed that the correlation with incidence of MACE in CAD patients within one year from strong to weak was northwest dryness syndrome plus blood stasis syndrome ［OR = 5.113， 95%CI （3.118， 8.387）， P＜0.001）］， blood stasis syndrome［OR = 4.630， 95%CI （2.394， 8.955）， P＜0.001］， northwest dryness syndrome ［OR = 4.395， 95%CI （2.642， 7.309）， P＜0.001］. ConclusionBlood stasis syndrome is the main syndrome type of CAD in Xinjiang Uygur Autonomous Region. CAD patients with northwest dryness syndrome are more likely to have blood stasis syndrome， and most suffer from both northwest dryness syndrome and blood stasis syndrome simultaneously. There is the strongest correlation between northwest dryness syndrome plus blood stasis syndrome and 1-year occurrence of MACE in CAD.
