Objective To explore the relationship between the expression levels of serum cingulate protein(CGN)and polyligand glycan 1(SDC-1)and the disease condition and outcome of hypertensive basal ganglia hemorrhage(HBGH).Methods A total of 123 patients with HBGH admitted to the Second People's Hospi-tal of Lianyungang from February 2019 to February 2022 were selected as the study objects,and 120 healthy volunteers who underwent physical examination in the hospital during the same period were selected as the health group.Serum CGN and SDC-1 expression levels were detected in the two groups.According to the dis-ease outcome,the patients were divided into the improved group(92 cases)and the deteriorated group(31 ca-ses).Receiver operating characteristic(ROC)curve and the area under the curve(AUC)were used to analyze the predictive value of serum CGN and SDC-1 expression levels on the disease outcome of patients with HB-GH.Results Serum CGN and SDC-1 expression levels in the severe group were higher than those in the mod-erate group and the mild group,and serum CGN and SDC-1 levels in the moderate group were higher than those in the mild group,and the differences were statistically significant(P＜0.05).Serum CGN and SDC-1 expression levels in HBGH patients in three groups were higher than those in health group,and the differences were statistically significant(P＜0.05).Serum CGN and SDC-1 expression levels in the deteriorated group were higher than those in the improved group,and the differences were statistically significant(P＜0.05).The AUC of serum CGN and SDC-1 for predicting the disease outcome of HBGH patients was 0.742(95％CI:0.792-0.697)and 0.861(95％CI:0.906-0.910),respectively,and the AUC of the combination of the two was 0.917(95％CI:0.962-0.870).The amount of blood loss and ventricular rupture in the deteriorated group were higher than those in the improved group,and the Glasgow Coma Scale(GCS)score on admission was lower than that in the improved group,and the differences were statistically significant(P＜0.05).Multi-variate Logistic regression analysis showed that serum CGN≥51.63 pg/mL(OR=3.815),serum SDC-1≥450.67 μg/L(OR=4.230)and GCS score ≤8(OR=5.333)were the influencing factors for disease outcome of HBGH patients(P＜0.05).Conclusion The increased expression levels of serum CGN and SDC-1 are closely related to the disease aggravation and the deterioration of the disease outcome in patients with HBGH,and they have certain predictive value for the disease outcome in patients with HBGH.

Objective To investigate the effect of triglyceride-glucose(TyG)index on the prognosis of elderly patients with decompensated heart failure(HF).Methods Clinical data of 305 patients(≥75 years old)with decompensated HF admitted to our hospital from January 2020 to Decem-ber 2023 were collected and retrospectively analyzed.According to the median TyG index,they were divided into high TyG index group(≥9.11,n=155)and low TyG index group(＜9.11,n=150).The results of laboratory tests,ambulatory blood pressure monitoring(ABPM),and echo-cardiography(ECG)were obtained from the electronic medical record system of our hospital.All patients were followed up by telephone within 28 d after discharge.The clinical characteristics were compared between the two groups.Spearman correlation analysis was used to analyze the re-lationship of TyG index with cardiac function and ABPM indicators of the patients.Kaplan-Meier survival curve was plotted to analyze the influence of the TyG index on the prognosis,and ROC curve was drawn to analyze the predictive value of the TyG index for 28-day mortality in these elderly patients.Results The high TyG index group had significantly higher mortality,thicker in-terventricular septum thickness(IVST),larger proportions of diabetes and hypertension,and higher levels of fasting blood glucose,cholesterol,triacylglycerol,NT-proBNP and coefficients of variation(CV)in 24-h SBP and 24-h DBP,and lower HDL-C level when compared to the low TyG index group(P＜0.05,P＜0.01).Spearman correlation analysis revealed that the TyG index was significantly positively correlated with IVST(r=0.526,P＜0.01),24-h SBP CV(r=0.342,P＜0.01),24-h DBP CV(r=0.302,P＜0.01)and NT-proBNP level(r=0.443,P＜0.01).Further-more,Kaplan-Meier survival analysis indicated that a significantly higher 28-day cumulative sur-vival rate was observed in the low TyG index group than the high TyG index group(94.67％vs 83.23％,log rank X2=10.436,P=0.001).Additionally,ROC curve analysis showed that the AUC value of TyG index in predicting 28-day mortality in elderly patients with decompensated HF was 0.692(95％CI:0.597-0.786).When the cutoff value of TyG inde x was 9.22,the sensitivity was 76.50％,and the specificity was 63.50％.Conclusion High TyG index indicates poor prognosis in elderly patients aged over 75 years with decompensated HF,and increment of TyG index may be helpful to identify high-risk HF population.

OBJECTIVE: To investigate the relationship between malnutrition and delirium and its effect on prognosis in elderly patients with severe pneumonia undergoing invasive mechanical ventilation. METHODS: A prospective observational study was conducted. Patients with severe pneumonia aged ≥ 60 years old who underwent invasive mechanical ventilation admitted to department of critical care medicine of the Second People's Hospital of Lianyungang from January 2021 to December 2022 were enrolled. The confusion assessment method (CAM) was used to evaluate the delirium of the patients in intensive care unit (ICU). The score of CAM ≥ 1 was defined as delirium. Mini nutritional assessment short-form (MNA-SF) was used to assess the nutritional status of patients, and MNA-SF score ≤ 7 was defined as malnutrition. Patients were divided into delirium group and non-delirium group according to whether delirium occurred. The differences in clinical indicators, length of ICU stay, duration of mechanical ventilation and wake-up time after drug withdrawal were compared between the two groups. After 28 days of short-term follow-up, the patients were divided into death group and survival group, and the differences in the incidence of delirium and malnutrition between the two groups were compared. Binary multivariate Logistic regression analysis was used to screen the risk factors for delirium in elderly patients with severe pneumonia undergoing invasive mechanical ventilation. Kaplan-Meier survival curve was used to analyze the effect of delirium on prognosis. RESULTS: A total of 132 elderly patients with severe pneumonia undergoing invasive mechanical ventilation were enrolled, of whom 98 survived and 34 died within 28 days, with a mortality of 25.76%. The incidence of malnutrition and delirium in the death group was significantly higher than that in the survival group (61.76% vs. 37.76%, 64.71% vs. 26.53%, both P < 0.05), and the MNA-SF score was significantly lower than that in the survival group (6.32±1.80 vs. 8.72±2.23, P < 0.01). Procalcitonin (PCT), interleukin-6 (IL-6) and blood lactic acid (Lac) in the death group were significantly higher than those in the survival group [PCT (μg/L): 4.47 (2.69, 10.39) vs. 2.77 (1.28, 5.94), IL-6 (ng/L): 204.08 (126.12, 509.85) vs. 120.46 (60.67, 290.99), Lac (mmol/L): 5.14 (2.75, 8.60) vs. 3.13 (2.16, 4.30), all P < 0.05], and the wake-up time after drug withdrawal was significantly longer than that in the survival group (minutes: 33.94±8.51 vs. 28.92±7.03, P < 0.01). Among 132 elderly patients with severe pneumonia undergoing invasive mechanical ventilation, 48 patients had delirium during ICU stay, and 84 patients did not have delirium. The incidence of delirium was 36.36%. The 28-day mortality in the delirium group was significantly higher than that in the non-delirium group (45.83% vs. 14.29%, P < 0.01), and the MNA-SF score was significantly lower than that in the non-delirium group (6.46±1.77 vs. 9.05±2.15, P < 0.01), the length of ICU stay, duration of mechanical ventilation, and wake-up time after drug withdrawal were also significantly longer than those in the non-delirium group [length of ICU stay (days): 13.40±9.59 vs. 10.06±7.81, duration of mechanical ventilation (hours): 197.06±89.80 vs. 138.81±82.30, wake-up time after drug withdrawal (minutes): 35.85±7.01 vs. 26.99±6.12, all P < 0.05]. Binary multivariate Logistic regression analysis showed that malnutrition [odds ratio (OR) = 7.527, 95% confidence interval (95%CI) was 2.585-21.917], Lac (OR = 5.345, 95%CI was 1.733-16.483), wake-up time after drug withdrawal (OR = 6.653, 95%CI was 2.021-21.904) were independent risk factors for delirium during ICU stay in elderly patients with severe pneumonia undergoing invasive mechanical ventilation (all P < 0.01). Kaplan-Meier survival analysis showed that the 28-day cumulative survival rate of patients in the delirium group was significantly lower than that in the non-delirium group (54.17% vs. 85.71%), and the difference was statistically significant (Log-Rank test: χ² = 16.780, P < 0.001). CONCLUSIONS The risk factors for delirium in elderly patients with severe pneumonia undergoing invasive mechanical ventilation during ICU stay include malnutrition, Lac, and wake-up time after drug withdrawal. The occurrence of delirium is closely related to poor prognosis.

Endovascular mechanical thrombectomy (EMT) has become the main treatment of acute ischemic stroke, but the pathological study of thrombi retrieved with EMT is still very limited. This article reviews the routine staining, special components, expression of immune factors, electron microscopic morphology, imaging features of the pathological components of thrombi retrieved with EMT, and their correlation with the etiological differentiation and outcomes of stroke.

Objective To investigate the effect of enteral nutritional support beginning at different time on aspiration events and immune function in the early post-traumatic (within 14 days) period in patients with severe traumatic brain injury.Methods From June, 2018, to February, 2021, 75 patients with acute traumatic brain injury admitted in the Department of Neurosurgery of the Second People's Hospital of Lianyungang were randomly divided into early feeding group (24 to 48 hours, n=35) and delayed feeding group (48 to 120 hours, n=40). The 14-day reflux rate, aspiration rate, incidence of aspiration pneumonia, immune indexes and complications were compared between two groups.Results There was no significant difference in the reflux rate, aspiration rate and the incidence of aspiration pneumonia between the two groups (P > 0.05). The levels of IgG, IgA, and complements C3 and C4 were significantly higher in the early feeding group than in the delayed feeding group (|t| > 1.720, P<0.001). The incidence of non-aspiratory lung infections was significantly lower in the early feeding group than in the delayed feeding group (χ2=4.728, P<0.05).Conclusion Initiating enteral nutrition within 24 to 48 hours after injury may preserve immune function and reduce the incidence of non-aspiratory lung infections in patients with severe traumatic brain injury.

Cardiac stroke is a stroke that occurs when a heart mural thrombus falls off and embolizes in the cerebral arterial system caused by various causes of heart disease, accounting for about 30% of all ischemic strokes. At present, in order to find evidence that emboli may originate from the heart, a large number of auxiliary examinations are needed. Good blood biomarkers are essential for the rapid identification of ischemic stroke in the emergency department. However, there is no breakthrough in this area. Brain natriuretic peptide is secreted in ventricular muscle and hypothalamus. It may be an important bridge between brain and heart diseases. However, the application of brain natriuretic peptide in the diagnosis and treatment of cardiogenic stroke is still very limited. This article reviews the current research status of brain natriuretic peptide levels and cardiogenic stroke and proposes further research trends and prospects.

Objective To observe the efficacy of combination therapy of calcium dobesilate dispersible and monosialotetrahexosylganlioside sodium on interleukin-6 (IL-6) and monocyte chemotactic protein-1 (MCP-1) in elderly patients with painful diabetic peripheral neuropathy.Methods From January 2012 to May 2017,in the Second People's Hospital of Lianyungang 70 patients of painful diabetic peripheral neuropathy,aged ≥60 years,were analyzed in this study.They were randomly divided into observation group (35 cases) and control group (35 cases).The observation group was treated with 40mg monosialotetrahexosylganlioside sodium dissolved in 250mL physiological saline,intravenous infusion per day,and oral calcium dobesilate dispersible 0.5g twice a day for two weeks.The control group was treated with methylcobalamin injection 0.5mg per day for two weeks.The clinical treatment effects and levels of IL-6 and MCP-1 were observed and compared between the two groups.Results After two weeks of treatment,the MDNS and MNSI scores of the observation group [(13.09 ± 5.38)points,(2.53 ± 1.19)points] were significantly lower than those of the control group [(18.31 ± 6.13) points,(4.19 ± 1.05) points,t =2.036,2.365,all P ＜ 0.05] and those before treatment [(21.26 ± 4.28) points,(5.40 ± 0.89) points,t =3.251,3.698,all P ＜ 0.05].The VAS-PI scores in the observation group [(6.24 ± 1.25) points,(4.13 ± 1.69) points] were significantly lower than those in the control group[(7.26 ± 1.28) points,(6.34 ± 2.65) points] at the first and second week (t =3.265,5.395,all P ＜ 0.05).The serum levels of inflammatory cytokines IL-6 and MCP-1 in the observation group [(15.16 ±0.88) ng/L,(157.19 ± 11.22) ng,/L] were significantly lower than those in the control group[(17.87 ± 1.19) ng/L,(198.21 ± 12.07)ng/L,t =2.152,1.365,all P ＜0.05]and those before treatment[(20.26 ± 1.05) ng/L,(260.44 ± 13.63) ng,/L,t =1.235,0.965,all P ＜ 0.05].Conclusion Combination of calcium dobesilate and mono-sialotetrahexosyl ganglioside may alleviate the sensory and pain sensations in patients with painful diabetic peripheral neuropathy,possibly by reducing the level of inflammatory cytokines IL-6 and MCP-1.

INTRODUCTIONPneumonia is associated with considerable mortality. However, there is limited information on age-specific prognostic factors for death from pneumonia.

METHODSPatients hospitalised with a diagnosis of pneumonia through the emergency department were stratified into three age groups: 18-64 years, 65-84 years and ≥ 85 years. Multivariate logistic regression and receiver operating characteristic curve analyses were conducted to evaluate prognostic factors for mortality and the performance of pneumonia severity scoring tools for mortality prediction.

RESULTSA total of 1,902 patients were enrolled (18-64 years: 614 [32.3%]; 65-84 years: 944 [49.6%]; ≥ 85 years: 344 [18.1%]). Mortality rates increased with age (18-64 years: 7.3%; 65-84 years: 16.1%; ≥ 85 years: 29.7%; p < 0.001). Malignancy and tachycardia were prognostic of mortality among patients aged 18-64 years. Male gender, malignancy, congestive heart failure and eight other parameters reflecting acute disease severity were associated with mortality among patients aged 65-84 years. For patients aged ≥ 85 years, altered mental status, tachycardia, blood urea nitrogen, hypoxaemia, arterial pH and pleural effusion were significantly predictive of mortality. The Pneumonia Severity Index (PSI) was more sensitive than CURB-65 (confusion, uraemia, respiratory rate ≥ 30 per minute, low blood pressure, age ≥ 65 years) for mortality prediction across all age groups.

CONCLUSIONThe predictive effect of prognostic factors for mortality varied among patients with pneumonia from the different age groups. PSI performed significantly better than CURB-65 for mortality prediction, but its discriminative power decreased with advancing age.

Objective To investigate the relationship between plasma tau protein, phosphorylated tau protein (p-tau) protein and cognitive function in subjects with generalized brain atrophy. Methods A total of 100 subjects with moderate and severe brain atrophy were divided into two groups according to cognitive function: normal group (n=50 cases) and dementia group (n=50 cases). And their gender, age, educational level, etc. are recorded. The tau protein and p-tau protein content in plasma were measured by double antibody sandwich enzyme-linked immunosorbent assay (ELISA). The differences between plasm tau and p-tau protein expression and their relationship with cognitive function were analyzed. Results Plasma tau protein and p-tau protein levels were significantly higher (P<0.05) in the dementia group [(210.92±43.79)pg/mL、(81.15±16.85)pg/mL] than in the normal group[(210.92±43.79)pg/mL、(81.15±16.85)pg/mL]. Plasma tau protein and p-tau protein levels were negatively correlated with the MMSE score (P<0.05) and had no significant correlation with the degree of brain atrophy (P>0.05). Conclusion Cognitive impairment may be associated with elevated tau protein levels in patients with extensive brain atrophy.

The objective was to investigate the hypoglycemic action of catalpol in spontaneous diabetes db/db mice. 40 db/db mice were randomly divided into fi ve groups: model control gourp; db/db plus catalpol 40, 80, 120 mg/kg body wt. groups and db/db plus metformin 250 mg/kg group. Age-matched db/m mice were selected as normal control group. The mice were administered with corresponding drugs or solvent by gavage for 4 weeks. The oral glucose tolerance test was carried out at the end of 3rd week. After 4 weeks of treatment, the concentrations of fasting blood glucose (FBG), glycated serum protein (GSP), insulin (INS), triglyceride (TG), total cholesterol (TC) and adiponection (APN) in serum were detected. The protein expressions of phosphorylation-AMPKalpha1/2 in liver, phosphorylation-AMPKalpha1/2 and glucose transporter-4 (GLUT-4) in skeletal muscle and adipose tissues were detected by western blot. Real time RT-PCR was used to detect the mRNA expressions of acetyl-CoA carboxylase (ACC) and Hydroxymethyl glutaric acid acyl CoA reductase (HMGCR) in liver. Our results showed that catalpol could significantly improve the insulin resistance, decrease the serum concentrations of INS, GSP, TG, and TC. The concentrations of APN in serum, the protein expression of phosphorylation-AMPKalpha1/2 in liver, phosphorylation-AMPKalpha1/2 and GLUT-4 in peripheral tissue were increased. Catalpol could also down regulate the mRNA expressions of ACC and HMGCR in liver. In conclusion, catalpol ameliorates diabetes in db/db mice. It has benefi t eff ects against lipid/glucose metabolism disorder and insulin resistance. The mechanism may be related to up-regulating the expression of phosphorylation-AMPKalpha1/2.
