Objective To construct a Nomogram prediction model for short-term prognosis of coronary heart disease(CAD)patients with hypertension after percutaneous coronary intervention(PCI)based on re-nin-angiotensin-aldosterone(ALD)system(RAAS)and Syntax score of coronary artery disease,so as to pro-vide a favorable basis for improving the prognosis of patients.Methods A total of 310 CAD patients with hy-pertension admitted to Jintang Hospital of West China Hospital of Sichuan University from June 2019 to April 2023 were selected.According to the ratio of 7:3,310 patients were randomly divided into a training set(217 cases)and a validation set(93 cases).All patients underwent PCI and were followed up for 3 months.The training set was further divided into poor prognosis group(n=68)and good prognosis group(n=148)ac-cording to the incidence of major adverse cardiovascular events(MACE).Multivariate Logistic regression model was used to analyze the risk factors of poor prognosis.The Nomogram prediction model was construc-ted by the R language in the training set,and the calibration curve and receiver operating characteristic(ROC)curve were used to verify the prediction efficiency of the model in the validation set.Results There was no significant difference in the general data between the training set and the validation set(P>0.05).MACE oc-curred in 68 cases(31.34％)in the training set and 28 cases(30.11％)in the validation set.There were sig-nificant differences in age,left ventricular ejection fraction,creatine kinase isoenzyme(CK-MB),number of diseased vessels,renin activity(PRA),angiotensin Ⅱ(ANG Ⅱ),ALD,preoperative Syntax score and N-termi-nal pro-B-type brain natriuretic peptide(NT-proBNP)between the good prognosis group and the poor prog-nosis group(P<0.05).Pearson correlation analysis showed that PRA,ANGⅡ,ALD were positively correla-ted with preoperative Syntax score(r=0.613,0.728,0.695,P<0.05).Lasso regression analysis included age,left ventricular ejection fraction,number of diseased vessels,PRA,ANG Ⅱ,ALD,preoperative Syntax score.Multivariate Logistic regression analysis showed that age,left ventricular ejection fraction,number of diseased vessels,PRA,ANG Ⅱ,ALD and preoperative Syntax score were independent influencing factors for poor short-term prognosis of PCI treatment(OR=4.448,5.153,4.571,3.875,4.914,4.468,5.224,P<0.05).The ROC curve showed that the area under the curve(AUC)of the Nomogram prediction model for poor short-term prognosis of CAD patients with hypertension after PCI in the training set and validation set were 0.884(95％CI 0.837-0.931)and 0.885(95％CI 0.818-0.953),respectively.The calibration curve showed that the prediction probability of poor short-term outcome of PCI in the training set and the validation set was basically consistent with the actual probability.Conclusion The short-term prognosis of CAD patients with hypertension after PCI is affected by age,left ventricular ejection fraction,number of diseased vessels,PRA,ANG Ⅱ,ALD,preoperative Syntax score and other factors.The Nomogram prediction model based on the above factors has high predictive value and good predictive utility.

Objective:To understand the incidence trend of brucellosis over time in Shandong Province from 2004 to 2023, and provide evidence for the prevention and control of brucellosis.Methods:The incidence data of brucellosis in Shandong from 2004 to 2023 were collected from China Disease Prevention and Control Information System. The annual change percentage (APC) and annual average change percentage (AAPC) of the incidence rate were calculated by using Joinpoint regression model. A age-period-cohort model was used to analyze changes in brucellosis incidence with age, period, and birth cohort.Results:The average annual incidence of brucellosis was 1.76/100 000 in Shandong from 2004 to 2023. The Joinpoint regression analysis results showed that the reported incidence of brucellosis increased by an average of 92.0% and 18.9% each year from 2004 to 2010 and from 2010 to 2014, respectively, and decreased by an average of 0.2% each year from 2014 to 2023. The results of APC model showed that the incidence of brucellosis increased first and then decreased with age ( χ2=176.92, P<0.001), and incidence of brucellosis showed slow increase and rapid increase first, then decrease ( χ2=2 921.03, P<0.001) over time. The risk for brucellosis reached peak in 2016 ( RR=5.29, 95% CI: 4.96-5.65) and became the lowest in 2006 ( RR=0.24, 95% CI: 0.21-0.28). The incidence increased in later birth cohort ( χ2=348.88, P<0.001), the AAPCs of all the age groups were between 15.0% and 40.0%, and the older the age, the greater the risk ( χ2=348.77, P<0.001). Conclusions:From 2004 to 2023, the reported incidence of brucellosis in Shandong showed a significant age-period-cohort effect, which increased first and then decreased, first increased and then decreased with age, increased slowly and rapidly first, then decreased over time, and increased in later birth cohort. It is necessary to conduct targeted prevention and control, health education to reduce the risk for brucellosis.

Objective:To investigate the changes in peripheral blood angiotensin-converting enzyme 2 (ACE2), high mobility group protein B1 (HMGB1) and interleukin 33 (IL-33) levels and their clinical significance in patients with primary lung cancer complicated by lung infection after surgery.Methods:The clinical data of 92 primary lung cancer patients treated at Longchang People′s Hospital from August 2018 to February 2021 were retrospectively collected, they were underwent radical lung cancer surgery, and were divided into the pulmonary infection group(27 cases) and the non-pulmonary infection group(65 cases) according to whether the patients had postoperative complications of pulmonary infection. The clinical data, peripheral blood ACE2, HMGB1 and IL-33 levels before and after surgery between the two groups were compared. The risk factors associated with postoperative pulmonary infection were analyzed by Lasso regression and Logistic regression. The predictive value of pulmonary infection was analyzed by receiver operating characteristic (ROC) curve. The cut-off values of peripheral blood ACE2, HMGB1 and IL-33 in the ROC curve were used as the boundary to divide the high level group and low level group, and the Kaplan-Meier survival curve was drawn to compare the survival rates of patients with high levels and low levels of peripheral blood ACE2, HMGB1 and IL-33.Results:The incidence of chronic obstructive pulmonary disease in the pulmonary infection group was higher than that in the non-pulmonary infection group: 40.74%(11/27) vs. 15.38%(10/65), there was statistical difference ( χ2 = 6.96, P<0.05). The levels of postoperative peripheral blood ACE2, HMGB1 and IL-33 in the pulmonary infection group were higher than those in the non-pulmonary infection group: (36.87 ± 9.87) mg/L vs. (25.94 ± 8.69) mg/L, (24.49 ± 8.14) μg/L vs. (16.74 ± 5.07) μg/L, (51.48 ± 8.25) ng/L vs. (39.88 ± 6.85) ng/L, there were statistical differences ( P<0.05). The results of Lasso regression and Logistic regression showed that the chronic obstructive pulmonary disease, postoperative peripheral blood ACE2, HMGB1 and IL-33 levels were independent risk factors for postoperative complications of pulmonary infection in patients with primary lung cancer ( P<0.05). The results of ROC curve showed that the area under the curve(AUC) values for postoperative peripheral blood ACE2, HMGB1 and IL-33 levels predicting postoperative complications of lung infection were 0.705, 0.821 and 0.768, respectively, and the AUC for the combination was 0.935. The risk of death in patients with high levels of postoperative peripheral blood ACE2, HMGB1 and IL-3 were 7.500, 4.874 and 2.857 times than the patients with low levels. Conclusions:Postoperative peripheral blood ACE2, HMGB1 and IL-3 levels in patients with primary lung cancer are important factors for pulmonary infection, which can be used for early prediction and evaluation after operation.

Objective:To investigate the significance of serum glycocholic acid (CG), total bile acid (TBA), and glucagon-like peptide-1 (GLP-1) in the transformation of fatty liver to liver cancer and their relationship with the body′s glucose and lipid metabolism.Methods:From May 2018 to August 2020, 96 patients with fatty liver (fatty liver group), 96 patients with liver cirrhosis (cirrhosis group) and 96 patients with liver cancer (liver cancer group) admitted to Jintang Hospital of West China Hospital of Sichuan University were selected. Ninety-six healthy physical examination patients were selected during the same period as the normal control group. Compared the general information, serum CG, TBA, GLP-1, glycosylated hemoglobin (HbA 1c), triacylglycerol (TG), total cholesterol (TC), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C) levels of each group. The correlation between serum CG, TBA, GLP-1 levels and the body′s glucose and lipid metabolism indicators were analyzed by Pearson correlation. The correlation between serum CG, TBA, GLP-1 and clinical stage were analyzed. Results:The levels of serum CG, TBA, GLP-1, and HbA 1c in the fatty liver group, cirrhosis group, liver cancer group were higher than those in the normal control group: (3.57 ± 1.06), (22.17 ± 8.44),(31.44 ± 9.65) mg/L vs. (1.26 ± 0.78) mg/L; (5.94 ± 1.26), (12.34 ± 4.02), (20.65 ± 5.17) μmol/L vs. (2.87 ± 0.59) μmol/L; (8.34 ± 1.55), (11.69 ± 3.26), (17.84 ± 2.78) pmol/L vs. (6.68 ± 1.24) pmol/L; (5.52 ± 0.31)%, (5.89 ± 0.27)%, (6.11 ± 0.23)% vs. (5.11 ± 0.36)%, and with the progression of the disease, the levels showed a rising trend, and the differences were statistically significant ( P<0.05). The levels of TG, TC, HDL-C, LDL-C in the cirrhosis group and liver cancer group were lower than those in the normal control group and fatty liver group, the differences were statistically significant ( P<0.05). The results of correlation analysis showed that serum CG, TBA, GLP-1 were positively correlated with HbA 1c ( P<0.05), and serum CG, TBA, GLP-1 were negatively correlated with TG, TC, HDL-C, and LDL-C ( P<0.05). With the increase of clinical stage, serum CG and TBA levels showed an increasing trend ( P<0.05). Conclusions:With the transformation of fatty liver to liver cancer, serum CG, TBA, and GLP-1 levels increase, and the change trend is closely related to the body′s glucose and lipid metabolism, which can provide a reference for the clinical improvement of fatty liver outcome evaluation mechanism.

Objective:To investigate the level of hypersensitive C-reactive protein (hs-CRP) in serum of patients with non-small cell lung cancer (NSCLC), and to explore the relationship between hs-CRP level and clinical characteristics and prognosis.Methods:The clinical data of 96 patients with NSCLC (NSCLC group), 50 patients with benign lung disease (benign lung disease group) and 45 normal subjects (control group) from August 2015 to August 2019 were analyzed. The expression of hs-CRP in serum were detected by immunofluorescence immunoassay. The tumor markers carcino-embryonic antigen (CEA), carbohydrate antigen 125(CA125), cytokeratin-19 fragment antigen (Cyfra21-1), neuronspecific enolase (NSE)were measured using automatic biochemical immunoassay. The relationship between hs-CRP and age, gender, tumor pathological type, clinical stage, imaging relief in patients with NSCLC were analyzed. The sensitivity, specificity and accuracy of hs-CRP combined with CEA, CA125, Cyfra21-1 and NSE were calculated.Results:The levels of hs-CRP in NSCLC group and benign lung disease group were higher than that in control group [(14.9 ± 7.5), (26.4 ± 10.2) mg/L vs. (5.1 ± 1.3) mg/L], and the differences were statistically significant ( P<0.05 or <0.01); the level of hs-CRP in NSCLC group was lower than that in benign lung disease group [(14.9 ± 7.5) mg/L vs. (26.4 ± 10.2) mg/L], and the difference was statistically significant ( P<0.05). The levels of CEA, CA125, Cyfra21-1, NSE in NSCLC group were higher than that in benign lung disease group and control group, and there were significant differences ( P<0.01 or<0.05). In 96 patients with NSCLC, there was 49 patients with elevated hs-CRP (hs-CRP elevated group) and 47 patients with normal hs-CRP (hs-CRP normal group). Single factor analysis showed that the level of hs-CRP had no correlation with age, gender and tumor pathological type ( P>0.05), but had correlation with clinical stage ( P<0.05). After detecting the lesions by CT, the rate of solid tumors in hs-CRP elevated group was 66.0%, in hs-CRP normal group was 40.8%, and there was significant difference ( χ2 = 6.089, P<0.05).After followed up for 2 months in NSCLC patients, the disease control rate in hs-CRP elevated group was 59.6%, in hs-CRP normal group was 85.7%, and there was significant difference ( χ2 = 8.300, P<0.01). The ensitivity, specificity and accuracy of hs-CRP combined with CEA, CA125, Cyfra21-1 and NSE was 89.0%, 80.4% and 82.3%. Conclusions:Patients with NSCLC have high expression of hs-CRP, which is correlated with disease progression and clinical treatment. The indicator of hs-CRP combined with CEA, CA125, Cyfra21-1 and NSE may be important for diagnosis and prognosis of NSCLC.

Objective To study the association between serum homocysteine (Hcy) level and cognitive impairment in PD patients.Methods Eighty-one PD patients admitted to our hospital were divided into normal cognition group (n=25),mild cognitive impairment group (n=32) and dementia group (n=24) with 19 healthy persons undergoing physical examination served as a control group.Their cognitive impairment was assessed according to their medical history,detailed physical examination data,Hoehn-Yahr scale score,MMSE score,and CDR score.Their serum levels of Hcy,folic acid and vitamin B12 were measured.The association of serum Hcy,folic acid and vitamin B12 levels with cognitive impairment was analyzed.Results The serum Hcy level was significantly higher in normal cognition group,mild cognitive impairment group and dementia group than in control group (P＜0.05,P＜0.01) and in dementia group than in normal cognition group (14.8±3.9 μmol/L vs 12.5±3.3 μmol/L,P＜0.05).The serum Hcy level was associated with oral levodopa and oral benserazide daily dose,oral levodopa and oral benserazide taking time,course of PD and age (r=0.298,P=0.000;r=0.280,P=0.000;r=0.301,P=0.000;r=0.184,P=0.019) but not associated with the severity of PD.Conclusion High serum Hcy level is one of the risk factors for cognitive impairment in PD patients,and control of oral levodopa dose contributes to the prevention and treatment of dementia in PD patients.

Objective To examine the caregivers' burden and quality of life (QOL) of main caregivers of patients with Parkinson's disease by analyzing caregiver and patient-related factors. Methods A total of 53 cases with Parkinson's disease seen from October 2012 to December 2013 in Yantaishan hospital of Yantai City were selected. Assessments: (a) EuroQol-5 questionnaires, including: EQ-5 dimensions (EQ -5d) and visual analogue scale (VAS). (b) Unified Parkinson's Disease Rating Scale. (c) Hoehn-Yahr(H-Y) stage; (d) Parkinson's disease sleep scale (PDSS), 15 items; (e) Hamilton Anxiety Rating Scale (HAMD-14), Hamilton Depression Rating Scale (HAMA-24); (f) Chinese version of Zarit caregiver burden interview. Results Spearman correlation analysis showed that the EQ-5D index and EQ-VAS negatively correlated with HAMD-14 of caregivers of Parkinson diseasepatients (r=- 0.318, - 0.046) (P<0.05), and negatively correlated with H-Y staging (r=-0.592, -0.531), UPDRSI (r=-0.434, -0.316) , UPDRS Ⅱ (r=0.521, 0.513) , UPDRS Ⅲ (r=0.520, 0.534), UPDRS Ⅳ (r=0.564, 0.509), PDSS in patients with Parkinson's disease (r=0.547, 0.490), HAMD-14 (r=0.315, 0.350), HAMA-24 (r=0.413, 0.401) of Parkinson's disease patients (P<0.05). Caregiver burden was related with HAMD-14 (r=0.496), HAMA-24 (r=0.551),H-Y stage (r=0.697), PDSS (r=0.659), UPDRS Ⅰ-Ⅳ (r=0.538, 0.668, 0.696, 0.600), EQ-5D index of Parkinson disease patients (r=0.682), EQ-VAS of Parkinson disease patients (r=0.670) (P<0.05); and positively related with anxiety of caregivers (r=0.275) , and a negative correlation with the caregivers' quality of lives (r=0.665) (P<0.05). Bivariate analyses showed significant correlations between caregiver burden and patients' sleep, scores of Parkinson's motor symptoms, and caregivers' depression. Based on multiple regression analysis, Zarit score proved to be the main predictor of caregivers' QOL. Caregivers' age, total numbers of caregivers and H-Y stage also proved to be a relevant factor. Conclusion Improvement of patient's sleep, motor symptoms anddepression might alleviate caregivers' strain. There is a correlation between caregivers' burden and QOL. QOL of caregivers can be improved through reducing their care-burden.

BACKGROUND:Pathogenesis of Parkinson’s disease is not completely understood, and there is yet no effective therapy that can prevent the neurodegenerative process of the disease fundamentaly. OBJECTIVE:To explore the effects of pituitary adenylate cyclase-activating polypeptide (PACAP) on lactacystin-induced Parkinson’s disease dopaminergic PC12 cel apoptosis and its molecular mechanism. METHODS: Under induction by nerve growth factors, PC12 cels differentiated into dopaminergic neurons, and then were treated with different concentrations of lactacystin for different time. When the cel survival rate was about 50%,the concentration and action time oflactacystin were selected to establish cel models of Parkinson’s disease. In the study, there were control group, lactacystin group, PACAP1-27 group (intervention group 1) and PACAP1-27+PACAP6-27 co-intervention group (intervention group 2). Changes of cel morphology were observed under inverted microscope; cel viability was detected with MTT method; the expression of endoplasmic reticulum stress specific protein caspase-12 was detected by western blot. Then the action of PACAP1-27 and PACAP6-27 to the cytoxicity of lactacystin was observed. RESULTS AND CONCLUSION: With different concentrations and action time of lactacystin, the viability of PC12 cels presented a concentration- and time-dependent decline. When the lactacystin at 20μmol/L acted for 24 hours, the cel viability was declined by about 50%. Under same conditions of lactacystin concentration and action time (20 μmol/L, 24 hours), the cels in the lactacystin group appeared to have damaged changes, declined cel viability, and increased caspase-12 activity in comparison with the control group (P< 0.01). Compared with the lactacystin group, the cel damage was relieved and cel viability was increased significantly in the intervention group 1 as wel as the expression of caspase-12 was decreased (P < 0.01). Experimental findings in the intervention group 2 were similar to those in the lactacystin group. These results suggest that lactacystin, an ubiquitin proteasome inhibitor, can lead to cel damage; PACAP1-27 plays a protective role by regulating the above-mentioned signal pathway. As one PACAP1-27 receptor antagonist, PACAP6-27 can attenuate this effect of PACAP1-27.

Objective To study the supporting role of traditional Chinese medicine GanFuAn in the treatment of high-risk state of liver cancer by color Doppler ultrasound.Methods Based on a number of joint detection of tumor markers,85 patients of liver cancer were selected from patients with chronic hepatitis B.Among these 85patients,50 patients were selected in a treatment group and treated with Chinese herbal preparation GanFuAn,with ultrasound and tumor markers serving as joint monitoring; while the other 35 patients were selected in a control group and treated with conventional treatment.Results In the treatment group,the liver tumor markers or liver tumor continually diminished.5 cases showed tumor disappear.38 cases showed effective results,while 7 cases showed no effects.The total incidence rate of liver cancer was 14％;while in the control group,none case showed tumor disappear.20 cases showed effects and 15 cases showed none effects.The cumulative incidence rate of liver cancer induced by chronic hepatitis was 43％,with all the cases have been confirmed by pathology.Conclusion Color doppler ultrasound was an intuitive,non-invasive dynamic method to monitor liver tumor's growth and decline.
