OBJECTIVE To establish anticoagulation pharmaceutical service model based on the integrated theory of health behavior change （ITHBC）， and analyze its effects. METHODS Referring to relevant literature and soliciting opinions from 8 experts from departments such as pharmacy， respiratory medicine， and vascular surgery， a anticoagulation pharmaceutical service model based on ITHBC was ultimately formed. VTE inpatients were selected from The First Affiliated Hospital of Shihezi University from December 2023 to June 2024 as the research subjects. They were randomly assigned into intervention group （58 cases） and control group （60 cases） using a random number table method. The intervention group implemented pharmacist-led anticoagulant pharmaceutical service model based on ITHBC， while the control group adopted a conventional anticoagulant pharmaceutical service model. The anticoagulation-related outcomes of two groups were compared after 3 months： anticoagulation compliance rate， the incidence of adverse drug reactions， the score of medication adherence and compliance rate of anticoagulant prescription； economic evaluation was conducted. RESULTS After implementing ITHBC-based anticoagulant pharmaceutical services for 3 months， the intervention group had higher anticoagulation compliance rate， score of medication adherence， and compliance rate of anticoagulant prescription than the control group （P＜0.05）. There was no statistically significant difference in the total incidence of adverse drug reactions between the two groups （P＞0.05）. For every 1% point increase in anticoagulant compliance rate， the hospital needed to invest 4.35 yuan additionally in anticoagulant pharmaceutical service fees. Compared with China’s per capita gross domestic product （GDP， 89 358 yuan） in 2023， the incremental cost-effectiveness ratio value that increased the anticoagulation compliance rate by 50% is far less than one time of per capita GDP. CONCLUSIONS The pharmacist- led anticoagulant pharmaceutical service model based on ITHBC can effectively improve the outcomes of anticoagulant therapy for VTE patients， enhance medication compliance， improve patients’ awareness and recognition of adverse drug reactions to anticoagulants， and has certain economic and social benefits.

Objective:To examine the burden and trends of acute viral hepatitis in Guangdong Province from 1990 to 2019, and provide reference evidences for hepatitis prevention and control in the province.Methods:Data on acute viral hepatitis (hepatitis A, B, C, and E) in Guangdong from 1990 to 2019 were extracted from the Global Burden of Disease Study 2019 database. The incidence, prevalence, mortality, and disability-adjusted life years (DALY) data were analyzed by age and gender, and the estimated annual percentage change (EAPC) was calculated to describe the changing trends in disease burden.Results:From 1999 to 2019, the standardized incidence, prevalence, mortality, and DALY of acute viral hepatitis in Guangdong were higher than the national averages. In 2019, 51.43% (2 245 087/4 365 221) of acute viral hepatitis cases in Guangdong Province were mainly attributed to hepatitis B, and 77.18% (106/138) of deaths were due to acute hepatitis B. In different age groups, except for acute hepatitis B, which was more common in adults, the incidence rates of other types of viral hepatitis such as hepatitis A, B, and E showed an overall decreasing trend with age. The mortality rates of different types of acute viral hepatitis, except for the <5 age group, increased with age. The overall incidence and mortality rates of acute viral hepatitis were higher in men than in women.Conclusions:The overall burden of acute viral hepatitis in Guangdong declined in 2019, but remained higher than the national level. Further efforts are needed to strengthen hepatitis prevention and screening in different population in Guangdong Province, especially in children and the elderly.

Objective To investigate the current status,obstacles,and specific needs associated with the application of transradial access(TRA)in peripheral interventions in Chinese hospitals,with the aim of promoting the broader adoption of TRA in interventional procedures.Methods The Committee of Interventional Oncology of China Anti-Cancer Association conducted a cross-sectional questionnaire survey to investigate and analyze the nationwide situation of TRA in peripheral interventional surgeries in 2022.Results Personnel from 60 hospitals participated in the questionnaire.The results showed that the number of peripheral interventionals performed using TRA was significantly lower than that performed using transfemoral access(TFA),with considerable variability among hospitals.The primary obstacles to the adoption of TRA were the lack of suitable catheters and the difficulty of radial artery puncture.Approximately 86.67％of the institutions expressed a high expectation for the innovation of new TRA-specific devices,particularly catheters,microcatheters,and guidewires.60.00％of medical institutions indicated a strong desire for systematic training and participation in multi-center clinical trials.Conclusions TRA peripheral intervention is feasible in many hospitals in China,however,systematic training and further promotion of TRA are essential.The innovation of new TRA-specific devices and TRA in peripheral intervention is urgent.

Objective:To investigate the correlation between triglyceride-glucose (TyG) index and high on-treatment platelet reactivity (HTPR) during clopidogrel treatment in patients with ischemic stroke.Methods:Patients with ischemic stroke who received maintenance dose of clopidogrel (75 mg/d) in the Department of Neurology, Guangdong Provincial Hospital of Chinese Medicine from January 2017 to March 2021 were retrospectively included. The highest quartile (Q4) of the TyG index was defined as insulin resistance. Platelet reactivity was assessed by thromboelastogram and clopidogrel HTPR was defined as the clot strength induced by adenosine diphosphate (MA ADP) >47 mm. Multivariate regression model was used to analyze the independent correlation between TyG index and platelet reactivity. Results:A total of 83 patients were included. The TyG index showed a linear correlation with MA ADP. The patients were divided into 4 groups according to the quartile of TyG index. The incidence of clopidogrel HTPR increased significantly with the increase of the quartile of the TyG index ( Ptrend=0.017). Multivariate analysis showed that there was a significant independent correlation between insulin resistance and clopidogrel HTPR (odds ratio 4.597, 95% confidence interval 1.285-16.446; P=0.019). Conclusions:In patients with ischemic stroke treated with clopidogrel, the incidence of clopidogrel HTPR gradually increases with the increase of the quartile of the TyG index. The insulin resistance assessed by the TyG index is independently associated with clopidogrel HTPR.

OBJECTIVE To s tudy the impr ovement effects of tilianin on the atherosclerosis （AS）model mice and its potential mechanism. METHODS Eight C 57BL/6J mice were taken as the normal group. Forty ApoE－/－ mice were randomly divided into model group ，tilianin low-dose ，medium-dose and high-dose groups [ 2.1，3.5，7.0 mg/（kg·d）] and simvastatin group [positive control drug ，3.5 mg/（kg·d）]，with 8 mice in each group. Normal group was given normal diet ，and other groups were given high-lipid diet to induce AS model. At the same time ，normal group and model group were given normal saline intragastrically ， administration groups were given relevant drug intragastrically ，once a day ，for 12 consecutive weeks. The levels of TC ，TG， LDL-C，HDL-C，Ox-LDL，IL-1β，IL-6，MCP-1 and TNF-α in plasma were determined. The pathomorphological changes of the aorta in mice were observed. The positive rate of ICAM- 1，VCAM-1 and PCNA in the aorta were determined. mRNA expressions of MMP- 2，MMP-9，TGF-β1，Smad2 and Smad 3 as well as protein expressions of TGF-β1，Smad2/3 and p-Smad 2/3 were also determined in aorta of mice. RESULTS Compared with normal group ，the plasma levels of TC ，TG，LDL-C，Ox-LDL，IL-1β， IL-6，MCP-1 and TNF-α in model group were increased significantly（P＜0.01），while HDL-C level was significantly reduced （P＜0.01）. Lipid plaques were formed in the aorta ，and the plaque area was large and caused severe stenosis of the lumen. mRNA expressions of MMP- 2，MMP-9，TGF-β1，Smad2 and Smad 3 as well as positive rate of ICAM- 1，VCAM-1，PCNA and protein expression TGF-β1，Smad2/3，and p-Smad 2/3 in the aorta were significantly increased （P＜0.01）. Compared with model group ， most of above indexes of medication groups were improved significantly （P＜0.05 or P＜0.01）. CONCLUSIONS Tilianin can inhibit the activation of TGF-β1/Smads signaling pathway and then inhibit the proliferation of vascular smooth muscle cells ，reduce ， inflammation and regulate lipid metabolism to inhibit the No.81960766） formation of AS.

Objective:To investigate the prognosis after salvage radiotherapy with or without hormone therapy for prostate cancer.Methods:From May 2014 to December 2020, 248 patients undergoing salvage radiotherapy due to prostate-specific antigen (PSA)persistence or biochemical progression after radical prostatectomy at Sun Yat-sen University Cancer Center (n=157) and West China Hospital, Sichuan University (n=91) were analyzed. Median age was 66 (45-78) years old. Median PSA was 23.50 (0.18-845.00) ng/ml. The number of PSA persistence and biochemical progression were 143 (59%) and 105 (42%). The number of pT 2, pT 3a, pT 3b, pT 4, and unknown T stage was 99, 49, 78, 15 and 7 cases.The number of N 0, N 1 and unknown N stage was 153, 44 and 51 cases. 165 cases had positive surgical margin. Gleason score of 6, 7, 8, >8 score and unknown was in 12, 104, 34, 90 and 8 patients. Early and late salvage radiotherapy was performed in 117 and 131 patients, and 70 patients (28%) were CRPC. Hormone therapy was used combined with radiotherapy in 182 patients (73%). PSA decline after radiotherapy was compared with Chi-squre test. Kaplan-Meier method and log-rank test were used to compare progression free-survival (PFS)after radiotherapy. Univariate and multivariate analyses of PFS were performed using Cox proportional hazards model. Early salvage radiotherapy was defined as PSA≤0.5 ng/ml before radiotherapy, and late salvage radiotherapy was defined as PSA>0.5ng/ml. Results:PSA response (PSA decline ≥50%) rate was 94% (233/248), and 82% (203/248) patients had PSA decline ≥ 90%. Twelve (5%) patients had rising PSA after completing radiotherapy, but only 4 (2%) had real progression. The median PFS was 69 months (95% CI 68-70), and 3-year and 5-year PFS rate were 80% and 67%. PFS of PSA persistence and biochemical progression were similar ( HR =0.71, 95% CI 0.37-1.37, P=0.311). Compared with late salvage radiotherapy, early salvage radiotherapy had better PFS [69 (95% CI 68-70) vs. 59 (95% CI 44-74) months, P<0.001]. Compared with hormone sensitive, castration-resistant was associated with worse PFS (5-year PFS rate 74% vs. 51%, P<0.001). In multivariate analysis, Gleason score>8, castration-resistant and late salvage radiotherapy were unfavorable prognostic factors. Conclusions:In patients receiving salvage radiotherapy with or without hormone therapy for PSA persistence and biochemical progression after radical prostatectomy, high PSA level before radiotherapy and castration resistant is associated with poor prognosis.

OBJECTIVE：To s tudy the effects of Dracocephalum moldavica total flavonoids （TFDM）on AMPK/SIRT 1/PGC-1α signaling pathway ，and to explore the mechanism of its protective effect on myocardial ischemia reperfusion injury （MIRI）rats. METHODS：Totally 50 healthy male SD rats were randomly divided into sham operation group ，model group ，TFDM group [ 60 mg/（kg·d），by extract] ，Compound C+TFDM group [ig administration of 60 mg/（kg·d）TFDM+intravenous injection of 250 μg/kg Compound C（AMPK inhibitor ）via tail vein 15 min before reperfusion] ，EX-527+TFDM group [ig administration of 60 mg/ （kg·d）TFDM+ip injection of 5 mg/kg EX- 527（SIRT1 inhibitor）20 min before reperfusion] ，with 10 rats in each group. They were given relevant medicine intragastrically ，once a day ，for consecutive 7 days. After last ig administration ，sham operation group underwent sham operation ，other 4 groups were established MIRI model by ligating left anterior descending coronary artery ， ischemia for 30 min and reperfusion for 2 h. After reperfusion ，the myocardial histopathological changes were observed by HE staining；RP-HPLC method was used to determine the contents of ATP ，ADP，AMP and NAD + in cardiac tissue. mRNA expressions of AMPK ，SIRT1 and PGC- 1α were detected by quantitative real-time PCR assay. Western blotting assay was the expressions of SIRT 1 and PGC- 1α protein in myocardium. RESULTS： Compared with sham operation group ， model group showed myocardial fib ers arranged disorder and horizontal stripes disappearance ，cell swelling burst and necrosis ，and nuclei deformation displacement ；the contents of ATP and NAD+，mRNA expression of AMPK ，SIRT1 and PGC- 1α，protein expression of SIRT 1 and PGC- 1α in cardiac tissue were decreased significantly （P＜0.05 or P＜0.01）；the contents of ADP and AMP ，the phosphorylation level of AMPK protein were increased significantly （P＜0.01）. Compared with model group ，myocardial pathological morphology were improved significantly in TFDM group ；the contents of ATP and NAD + in cardiac tissue ，mRNA expression of AMPK ，SIRT1 and PGC- 1α，the phosphorylation level of AMPK protein ，the protein expression of SIRT 1 and PGC- 1α were increased significantly（P＜0.05 or P＜ 0.01），while the contents of ADP and AMP were decreased significantly （P＜0.01）. Compared with TFDM group ，improvement effects of Compound C + TFDM group and EX- 527 + TFDM group on above indexes were reversed （P＜0.05 or P＜0.01）. CONCLUSIONS：TFDM may play a protective role on myocardium by activating AMPK/SIRT 1/PGC-1α signaling pathway and regulating energy metabolism.

Objective: To predict the efficacy of endoscopic tissue adhesives in the treatment of gastric varices in patients with liver cirrhosis by Nomogram model. Methods: From August 2014 to September 2017, 158 patients with liver cirrhosis caused esophagogastric variceal bleeding and received endoscopic tissue adhesives treatment at Zhongshan Hospital, Fudan University were collected. All patients were followed for 12 months. The primary outcome was rebleeding. The factors of rebleeding after endoscopic treatment of esophagogastric varices were analyzed. Nomogram prognostic model was developed and compared with Child-Pugh grading, computed tomography angiography (CTA) and hepatic venous pressure gradient (HVPG) in prognostic accuracy in rebleeding after endoscopic treatment in liver cirrhosis caused esophagogastric varices. Univariate and multivaricate Cox regression analysis, Kaplan-Meier curve and log-rank test were performed for statistical analysis. Results: During the follow-up, rebleading occurred in 18 cases (11.4%), 37 cases (23.4%) and 49 cases (31.0%) at 2, 6, and 12 months after endoscopic treatment. The results of univariate Cox regression analysis showed the risk factors of rebleeding after endoscopic treatment of gastric varices included gender, alcoholic liver cirrhosis, diabetes mellitus, Child-Pugh grade (Grade A vs. B or C), extraluminal vessels on CTA (presence vs. absence) HVPG (<16 mmHg vs. ≥16 mmHg, 1 mmHg = 0.133 kPa), extensive portal embolism, esophageal varices, type 2 gastric varices, injection points of tissue adhesive (≤3 points vs. > 3 points), injection volume of tissue adhesive (≤ 3 mL vs. > 3 mL) (hazard ratio (HR)=0.575, 2.018, 1.562, 3.433, 2.945, 1.859, 2.743, 0.324, 1.840, 1.477, and 1.716; 95% confidence interval (CI) 0.305 to 1.084, 0.902 to 4.514, 1.753 to 6.724, 1.663 to 5.217, 1.012 to 3.415, 0.852 to 8.830, 0.079 to 1.335, 1.012 to 3.317, 0.839 to 2.602, and 0.935 to 3.152; all P<0.2). The results of multivariate Cox regression analysis indicated that Child-Pugh grade, extraluminal vessels by CTA, and HVPG (HR = 2.095, 95% CI 1.099 to 3.995, P = 0.025) were all independent risk factors of rebleeding after endoscopic treatment of gastric varices (HR=2.665, 2.886, and 2.095; 95% CI 1.339 to 5.300, 1.580 to 5.271, and 1.099 to 3.995; all P<0.05). Kaplan-Meier curves showed that Child-Pugh grade (Grade A vs. B or C), extraluminal vessels on CTA (presence or absent) and HVPG (<16 mmHg vs. ≥16 mmHg) could effectively predict cumulative non-rebleeding rate in one year after endoscopic treatment of gastric varices, and the differences were statistically significant (all P<0.05). Receiver operataring characteristic curve analysis demonstrated that the predictive value of the model combined with Child-Pugh grade, extraluminal vessels on CTA and HVPG was higher than that of Child-Pugh grade and HVPG (AUC=0.746, 0.673 and 0.585; 95% CI 0.662 to 0.829, 0.583 to 0.762, and 0.486 to 0.683; P<0.01, P=0.001 and P=0.089, respectively). Patients were divided into low, medium, and high-risk groups according to the 25th and 75th percentiles of the Nomogram score. The results showed that Nomogram model could effectively distinguish high-risk groups of rebleeding after endoscopic treatment of gastric varices, and the difference was statistically significant (P <0.01). Conclusions Extraluminal vessels on CTA, HVPG and Child-Pugh grade are independent prognostic evaluation indexes of rebleeding after endoscopic treatment of gastric varices. The predictive accuracy of Nomogram model based on these three prognostic factors may be better than Child-Pugh grade and HVPG.
