Objective To explore the effect of Internet+cardiac rehabilitation on hypertension patients with coronary heart disease.Methods 80 patients with hypertension and coronary heart disease admitted to our hospital from January 2022 to April 2023 were randomly divided into the combined group(n=40)and the conventional group(n=40).Both groups were given routine cardiac rehabilitation interventions.The combined group combined adoptionof the Internet for continuous interventionson the basis of routine cardiac rehabilitation interventions.Compare the oxygen uptake,blood pressure,compliance,and self-management scores between two groups before intervention and three months after discharge.Results The AT Mets,AT VO2,peak VO2,and expected value compliance ratio in the combined group were all higher than those in the conventional group(P<0.05);The systolic and diastolic blood pressure in the combination group were lower than those in the control group,and the proportion of complete compliance was significantly higher than that in the control group(P<0.05);The self-management scores of the joint group were higher than those of the conventional group(P<0.05).Conclusion The continuous interventions of Internet plus cardiac rehabilitation can control the blood pressure of patients with hypertension and coronary heart disease,and patients'compliance behavior is significantly im-proved,andthus improving patients'self-management ability,which can be used for reference and promotion in clinical practice.

Objective:To investigate the effects of survival status in Stanford type A aortic dissection (TAAD) patients over 70 years old by different treatment methods.Methods:The clinical data of 151 TAAD patients over 70 years old from January 2012 to January 2022 in the Affiliated Hospital of Jining Medical University were retrospectively analyzed. Among them, 60 patients were treated with surgery (surgical treatment group), and 91 patients with conservative method (conservative treatment group). The duration of hospitalization and complications (including pericardial effusion, acute myocardial infarction, pericardial tamponade, shock, stroke, mesenteric ischemia and acute renal failure) were recorded. The patients were followed up within 30 d after the onset of illness. The survival status was recorded. The multivariate Cox regression analysis was used to analyze the independent risk factors of death in TAAD patients over 70 years old.Results:The duration of hospitalization in surgical treatment group was significantly longer than that in conservative treatment group: 14.00 (7.00, 19.75) d vs. 5.00 (2.00, 10.00) d. The incidences of pericardial tamponade, shock and acute renal failure: 1.7% (1/60) vs. 13.2% (12/91), 8.3% (5/60) vs. 24.2% (22/91) and 0 vs. 9.9% (9/91), with statistical differences ( P<0.01 or <0.05), but no statistical differences in the incidences of pericardial effusion, acute myocardial infarction, stroke, mesenteric ischemia between two groups ( P>0.05). Patient follow-up for 30 d, the mortality rate in surgical treatment group was significantly lower than that in conservative treatment group: 15.0% (9/60) vs. 46.2% (42/91), with statistical difference ( χ2 = 15.69, P<0.01). The multivariate Cox regression analysis result showed that conservative treatment, female, increased aortic root diameter and concomitant stroke were the independent risk factors of death in TAAD patients over 70 years old ( RR = 2.311, 2.135, 1.051 and 3.737; 95% CI 1.056 to 5.057, 1.083 to 4.212, 1.004 to 1.100 and 1.393 to 10.026; P<0.05 or <0.01). Conclusions:The early surgical treatment is recommended in TAAD patients over 70 years old with surgical indications.

OBJECTIVE To study the quality difference of different specifications of Citri Grandis Exocarpium from different origins，and to provide reference for the orderly development of Citri Grandis Exocarpium industry. METHODS Different specifications [ Citrus grandis ‘Tomentos’young fruit ，Citrus grandis （L.）Osbeck young fruits ，exocarp] of 93 batches of Citri Grandis Exocarpium medicinal materials （decoction pieces ）from different origins [ Citrus grandis ‘Tomentosa’or Citrus grandis （L.）Osbeck] were taken as samples. The contents of naringin and rhoifolin in samples were determined by HPLC. Through pheatmap parameters of R language ，heatmap was drawn for the contents of naringin and rhoifolin according to origins and specifications （young fruit and exocarp ）. RESULTS Of 93 batches of samples ，the contents of naringin and rhoifolin were 16.52-214.64 and 1.03-10.96 mg/g，respectively. Among different specifications ，the contents of naringin and rhoifolin in the young fruit were the highest （their average contents were 108.96 and 6.30 mg/g respectively ）. Heatmap analysis of R language content showed that the contents of naringin and rhoifolin in Citri Grandis Exocarpium from origin of C. grandis ‘Tomentosa’were generally higher than those from origin of C. grandis （L.）Osbeck. Of different specifications of Citri Grandis Exocarpium from origins，the contents of naringin and rhoifolin were higher in KTP young fruit relatively. CONCLUSIONS The quality of Citri Grandis Exocarpium from origin of C. grandis ‘Tomentosa’with the young fruit as specification is the best.

Objective:To investigate the technical method and clinical efficacy of CT-guided radioactive 125I seed implantation (RISI) assisted by 3D-printed coplanar template(3D-PCT) in the treatment of metastatic tumors of chest wall, and analyze the influence of dosimetric parameters on the treatment efficacy. Methods:A retrospective analysis was conducted for 55 patients with metastatic tumors of chest wall treated with 3D-PCT-assisted 125I radioactive seed implantation in Tengzhou Central People′s Hospital from January 2014 to March 2021.Preoperative plans were made using a brachytherapy treatment planning system, and dosimetric parameters were assessed at 3d after surgery. During regular CT reexaminations after surgery, the local control rate and overall survival (OS) rate were calculated and the pain relief degree and complications were assessed. The Logrank test and Cox regression were used for univariate and multivariate analyses of local control time (LCT). Meanwhile, receiver operating characteristic (ROC) curves were plotted to analyze the critical values of dosimetric parameters and to predict the LCT. Results:The 1-, 2-, and 3-year OS rates ofthe 55 patients were 72.7% (40/55), 21.8% (12/55), and 16.4% (9/55), respectively.The local control rates of 3, 6, 12, and 24 months were 96.4%(53/55), 86.5%(45/52), 85.0%(34/40), and 91.7%(11/12), respectively. There was no statistically significant difference between postoperative and postoperative dosimetric parameters of GTV, particle number, D90, D100, V100, V150, V200, CI, EI, and HI ( P> 0.05). Compared with postoperative V90, the postoperative V90 decreased with a statistically significant difference( P=0.006). As indicated by the univariate Cox regression analysis, the pathological grade, D90, D100, V90, and V200had significant effects on the LCT( P<0.05). Among them, the pathological grade and D90 were independent influencing factors of the LCT, while the other factors showed no statistically significant difference according to the multivariate Cox regression analysis.The LCT of patients with D90≥127 Gy was significantly longer than that of patients with D90<127 Gy (χ 2=16.61, P=0.000). The pain relief rate was 80.8%(21/26) after three months. Five cases suffered from grade Ⅰ-Ⅱ radioactive dermatitis and one case experienced grade Ⅲ radioactive dermatitis. Conclusions:The 3D-PCT-assisted CT-guided 125I radioactive seed implementation can achieve precise and controllable dose and definite efficacy in the treatment of metastatic tumors of chest wall, with few complications.The LCT was remarkably prolonged in the case of D90≥127 Gy, and D90 is an independent influencing factor of the LCT.

Objective:To investigate the clinical characteristics of the coronavirus disease 2019 (COVID-19) with liver injury and to provide evidence for clinical diagnosis and treatment.Methods:The clinical data of 107 cases of COVID-19 with liver injury admitted to Guangzhou Eighth People′s Hospital from January 20, 2020 to February 17, 2020 were retrospectively analyzed. SPSS 20 was used for statistical analysis. Comparison of data between the two groups was performed by Mann-Whitney U test, and P<0.05 was statistically significant. Results:The proportion of COVID-19 patients with liver injury was 38.5%. Among the 107 patients, 53 were males and 54 were females, with a median age of 57 years. Among the 52 cases with basic diseases, 20(38.5%) cases had chronic liver diseases(including fatty liver and viral hepatitis). Patients had clinical manifestations of fever (86.0%), cough (92.5%), nausea and vomiting (29.0%), and diarrhea (21.5%). All the indexes of liver function were abnormal in different degree, 31.8% of patients had the total bilirubin (TB) increased, while 60.7% and 63.6% of patients had alanine aminotransferase (ALT) and aspartate aminotransferase (AST) increased respectively. The serum albumin (ALB), prealbumin (PAB), cholinesterase (CHE), prothrombin activity (PTA) decreased in 86.9%, 88.8%, 17.8% and 7.5% of patients, respectively. The level of TB, ALT, AST was higher in patients with severe or critical disease than in patients with light or common disease( Z=-2.3089, P=0.037; Z=-2.611, P=0.009; Z=-3.298, P=0.001), while ALB, PAB, CHE, PTA decreased more significantly( Z=5.527, P=0.000; Z=-2.324, P=0.020; Z=-3.119, P=0.002). Compared with the patients without basic chronic liver disease, the transaminase of the patients with basic chronic liver disease increased more significantly ( Z=-2.218, P=0.027; Z=-1.982, P=0.047). The TB level of patients treated with LPV/r was significantly higher than that of patients without LPV/r ( Z=-3.079, P=0.002). Conclusions:Liver injury is one of the common complications of COVID-19. Patients in severe or critical condition and with basic chronic liver diseases have severe liver injury. We should pay more attention to the liver injury effect of drugs.

OBJECTIVE: To compare the accuracy of five warfarin-dosing algorithms and warfarin stable dose model (2.5 mg/day) for Shandong population. METHODS: One hundred and twenty five patients who achieved stable warfarin dose were enrolled. Clinical and genetic data were used to evaluate the value of each algorithm by calculating the percentage of patients whose predicted warfarin dose was within 20% of the actual stable therapeutic dose and mean absolute error (MAE). RESULTS: The frequency of patients with CYP2C9*1/*1, CYP2C9*1/*3 and CYP2C9*1/*2 genotype was 92.00%, 7.20%, 0.80%, respectively. That of VKORC1-1639 AA, AG and GG genotype was 82.40%, 15.20%, 2.40%, respectively. CYP4F2*1/*1, *1/*3, *3/*3 genotype was 50.40%, 39.20%, 10.40%, respectively. With the same genotypes for other loci, patients who carried at least one VKORC1-16398G mutant allele had increased warfarin stable daily dose compared with VKORC1-1639AA. Compared with CYP4F2*1/*1, those carrying at least one CYP4F2*3 mutant allele had warfarin stable daily dose increased by 5.9%-13.00%. The percentage of ideal prediction calculated from IWPC model (59.20%), Huang model (57.60%) and Ohno model (52.80%) were higher than others. The MAE were 0.35 (95%CI: 0.11-0.49), 0.15 (95%CI: 0.10-0.32), 0.39 (95%CI: 0.12-0.51), respectively. CONCLUSION The polymorphisms of CYP2C9, VKORC1 and CYP4F2 genes can influence the stable dose of warfarin in Shandong population. IWPC algorithm is suitable for guiding the use of warfarin in this population.

Purpose: Fractionated radiotherapy as well as concomitant and adjuvant chemotherapy such astemozolomide for postoperative high-grade glioma (HGG) patients improves progressionfreesurvival and overall survival. Multiple factors such as chemotherapy, radiotherapy,tumor grade, residual tumor volume, and genetic modifications might play a role in the formationof cognitive impairment. The risk factors of cognitive impairment in postoperativepatients with HGG receiving radiotherapy and chemotherapy remains a concern in this population.The purpose of this study was to identify risk factors for cognitive impairment inpatients of postoperative HGG. Materials and Methods: A total of 229 patients with HGG who underwent surgery were analyzed. Cognitive impairmentwas defined as a decrease of Cognitive Assessment Montreal (MoCA)’s score in atleast two cognitive domains or any MoCA’s score of less than 26 points at the time of studycompared with baseline level. Multiple potential risk factors including methylated status ofthe O6-methylguanine-DNA methyltransferase (MGMT) promoter, glioma World HealthOrganization (WHO) grade, residual tumor volume, education, and sex were analyzed. Coxunivariate and multivariate regression analysis was used to detect the significant risk factorsfor cognitive impairment. Results: At the end of follow-up among the 229 patients, 147 patients (67%) developed cognitiveimpairment. 82 patients (36%) remained in normal cognitive condition. In multivariate analysis,unmethylated MGMT promoter (hazard ratio [HR], 1.679; 95% confidence interval [CI],1.212 to 2.326; p=0.002), glioblastoma (HR, 1.550; 95% CI, 1.117 to 2.149; p=0.009),and residual tumor volume > 5.58 cm3 (HR, 1.454; 95% CI, 1.047 to 2.020; p=0.026) wereindependent risk factors for cognitive impairment. Conclusion Methylated status of the MGMT promoter, glioma WHO grade, and residual tumor volumemight be risk factors for the cognitive impairment in postoperative patients with HGG.

Objective To observe the effects of color retention treatment on the preservation of medicinal plant herbariums, film-cover specimens and resin specimens. Methods Seven kinds of medicinal plants with different characters after color retention treatment were made into herbariums, film-cover specimens and resin specimens, and then the preservation results for the above three kinds of medicinal plant specimens with or without color retention treatment were compared. Results Resin and film-cover specimens without color retention treatment had better preservation results than herbariums. All of the three kinds of specimens with color retention treatment had better preservation results for the original color and shape than the specimens without color retention treatment. Conclusion Color retention treatment for the medicinal plants results into higher preservation quality of the herbariums and longer preservation period.
