OBJECTIVE To develop a whole-process intelligent model of pharmaceutical care for peritoneal dialysis （PD） patients， and to provide a reference for clinical pharmacists to provide standardized PD pharmaceutical care. METHODS The pharmaceutical care mode of PD patients at home and abroad was investigated and analyzed. Based on the actual situation of the First Affiliated Hospital of Soochow University （hereinafter referred to as “our hospital”）， with “home→PD center outpatient→ inpatient department” as the main node， the recycling process of medication reconciliation was optimized. The whole-process intelligent pharmaceutical care model of PD was illustrated by improving the Chinese version of the drug-related problems （DRPs） classification tool， developing the corresponding pharmaceutical care process， and presenting specific cases. RESULTS Based on the medication therapy management （MTM） platform， our hospital had built a closed-loop PD whole-process intelligent pharmaceutical care model of “in-hospital pharmaceutical care （building document）-PD outpatient MTM-home pharmaceutical care （online App management）”. A “double cycle” workflow of “admission→discharge→outpatient” medication reconciliation cycle and “discovery-analysis-intervention-follow-up-record-evaluation” DRPs cycle was formed. CONCLUSIONS The establishment of the whole-process intelligent pharmaceutical care model for PD in our hospital provides experience for standardizing pharmaceutical care for PD patients， and can reduce DRPs.

The robustness of sliding mode control is utilized to improve the adaptability of the control system to changes in vascular mechanical properties of different patients.Adaptive sliding mode control is designed to adapt the controller to the needs of different virtual environment simulations through an adaptive mechanism,thereby weakening the chattering of sliding mode control.The extrapolation prediction algorithm is invoked under the adaptive sliding mode control to reduce the effects of delay on the control and improve force feedback transparency.The experimental results demonstrate that adaptive sliding mode predictive control can enhance system stability,force feedback control accuracy,and fidelity of force feedback control system for flexible surgical instruments.The study has important theoretical significance and practical value for the design of systems with flexible control objects and the improvement of force feedback fidelity.

Objective To investigate the epidemiological characteristics and risk factors of tuberculosis in Cangzhou from 2010 to 2020. Methods A total of 325 patients diagnosed with pulmonary tuberculosis in Cangzhou Hospital of Integrated Traditional Chinese and Western Medicine from January 2010 to December 2020 were selected as the study group. At the same time, 348 healthy adults who had a physical examination in the same hospital were selected as the control group. The epidemiological characteristics of 325 patients were analyzed. The age, gender, occupation, annual family income, marital status, drinking history, smoking history, education level and tuberculosis contact history of the two groups were compared to analyze the risk factors of tuberculosis. Results The epidemiological and statistical analyses found that among 325 cases of tuberculosis patients, patients ≥60 years old accounted for a relatively high proportion (71.08%). The majority of patients were male by gender (58.15%), and the majority of patients were farmers by occupation (47.69%). The incidence seasons were mainly in winter (40.62%) and spring (29.85%). The results of univariate analysis showed that there were statistically significant differences in gender, occupation, age, history of exposure to tuberculosis, and history of smoking between the two groups (P<0.05). Multivariate analysis found that ages ≥60 years old, male, history of smoking, farmers, and history of exposure to tuberculosis were risk factors for the onset of tuberculosis (P<0.05). Conclusion In Cangzhou, people aged over 60 years, male and farmers are prone to contract tuberculosis, and the peak time of the disease is in spring and winter. The development of corresponding prevention and control measures based on these characteristics is of great significance for the prevention and control of tuberculosis.

Objective:To explore the application value of skin lead marker combined with iSCOUT image-guided positioning system in monitoring and correcting the setup error of intensity-modulated radiotherapy (IMRT) for breast cancer and calculate the PTV margin, aiming to provide reference for clinical practice.Methods:25 breast cancer patients treated with IMRT after modified radical mastectomy in Fujian Medical University Union Hospital from April to August 2019 were enrolled in this study. The skin lead marker combined with iSCOUT image-guided positioning system was employed for image-guided positioning based on the gold standard registration algorithm. Initial setup errors on the x (lateral), y (craniocaudal) and z (anteroposterior) axis and residual errors after the position correction were recorded and analyzed. The effect of the errors before and after image-guided correction upon the plan dose was compared and the reasonable PTV margin was calculated.Results:25 patients received 150 times of positioning verification using skin lead marker combined with iSCOUT image-guided positioning system. The absolute residual errors on the x-, y-and z-axis were (1.53±0.96), (1.30±0.99) and (1.34±0.92) mm, significantly smaller than the initial setup errors of (2.63±2.12), (2.41±2.45) and (3.07±2.77) mm (all P<0.001). The percentage of dose deviation due to residual errors was also smaller than that of the initial errors. Significant differences were observed in D 98%, D 2%, D max of PTV, D max of the heart, D max of the healthy breast, and D mean of the affected lung and both lungs. The percentage deviation from the original plan was decreased from 2.18%, 3.19%, 10.66%, 8.75%, 48.21%, 10.50%, and 3.66% to 0.38%, 0.23%, 2.31%, 0.04%, 13.78%, 6.35% and 0.41%, respectively (all P<0.05). PTV margins on the x-, y-and z-axis after correction were calculated as 1.87, 1.75 and 1.69 mm, respectively. Conclusion:It is feasible and valuable to apply the skin lead marker combined with iSCOUT image-guided positioning system in the positioning verification and correction of breast cancer radiotherapy position, providing novel reference for clinical PTV margin.

Objective:To investigate regional distribution and clinicopathological features of Epstein-Barr virus associated gastric cancer (EBVaGC).Methods:Epstein-Barr virus encoded RNA (EBER)was detected in 4 081 cases of gastric adenocarcinoma in Cancer Hospital, Chinese Academy of Medical Sciences by using in situ hybridization. EBVaGCs were identified and their proportions in different provinces, autonomous regions and municipalities were compared. The correlation between EBVaGC and clinicopathological features was also analyzed.Results:A total of 3.0% (123/4 081) patients with gastric adenocarcinoma are EBVaGCs. Among the areas with cases more than 90, the highest proportion of EBVaGC was found in Jilin province, accounting for 7.6%, and then followed by 5.4% in Liaoning province, 4.1% in Anhui province, 3.9% in Beijing, 3.7% in Inner Mongolia Autonomous Region, 3.4% in Shanxi province, 3.0% in Heilongjiang province, 2.1% in Shandong province, 1.6% in Hebei province, and no EBVaGC was found in Henan province. EBVaGC proportions are significantly different in these provinces, autonomous regions and municipalities ( P<0.05). Multivariate analysis of logistic regression revealed that gender ( OR=2.231, 95% CI: 1.290~3.858), WHO classification ( OR=2.338, 95% CI: 2.051~2.664) and N stage ( OR=0.420, 95% CI: 0.284~0.621) were independent impact factors for EBVaGC. The proportion of EBVaGC was higher in males, gastric carcinomas accompanied with lymphoid stroma and patients without lymph node metastasis. Conclusions:The proportion of EBVaGC in gastric adenocarcinoma displays area distribution disparity in China. The gender, WHO classification and N stage are closely associated with EBVaGC.

Objective To analyze the relationship between planning factors of intensity-modulated radiation therapy (IMRT) and gamma index and investigate the effect of each parameter upon the γ passing rate of IMRT.Methods Gamma analysis was performed using 3％/3 mm acceptance criteria for 457 IMRT beams with different planning factors.During multi-factor ANOVA analysis of planning factors and gamma passing rate,the control variables primarily included the minimum segment area,minimum number of monitor unit (MU),number of segment,segment conversation,and the spatial resolution in the measured dose distribution.Results The percentage of pixels with passingγsignificantly differed under different minimum segment area,segment conversation and the spatial resolution in the measured dose distribution (all P＜ 0.05).No significant correlation was observed between the passing rate and the minimum number of MU and the number of segment (P＞ 0.05).Conclusions According to the actual situation of the equipment,the minimum segment area should be determined during IMRT planning.Direct machine parameter optimization should be performed.Appropriate resolution of the plane dose images can be chosen according to the minimum detector interval of dose matrix device,

Background and purpose: The literature on dose-volume parameters and pneumonitis is extensive. The results are inconsistent, both for the best predictive metrics and significant comorbid factors. This study aimed to investigate a prospective functional equivalent uniform dose (fEUD) with perfusion single photon emission computed tomography (SPECT) images as predictors of radiation pneumonitis (RP) in patients undergoing curative radiotherapy (RT). Methods: Functional lung imaging was performed using SPECT for perfusion imaging. Perfusion factors were defined as the mean percentile perfusion levels of the 4 areas, top to 75%, 75% to 50%, 50% to 25%, 25% to 0%, re-spectively. fEUD was calculated from perfusion factors and standard dose-volume parameters extracted from treatment planning computed tomography (CT) scans. Total lung (TL), ipsilateral (IL) and contralateral lung (CL) volumes minus gross tumor volume (GTV), whole-lung V5, V20, whole lung fEUD, IL and CL fEUD, and general equivalent uniform dose (gEUD) were analyzed to evaluate correlations between RP using Common Terminology Criteria for Adverse Events (CTCAE) version 4.03. Statistical significance was defined as P<0.05. Results: A total of 15 patients treated with intensity modulated RT or 3D conformal RT were analyzed, grades≥3 RP were observed in 6 patients. There was only a trend toward significance for unilateral (UL) fEUD of higher dose side (P=0.007). Whole-lung V5, V20 were almost identical between patients who developed pneumonitis and patients who did not, as the values were below the recommended thresholds from published papers. Unilateral fEUDs were linear with unilateral gEUDs (t=0.815, P=0.000). Conclusion: SPECT-based equivalent uniform dose appears to be a better predictor of RP compared to stan-dard dose-volume parameters. Planning constraints should aim to keep unilateral fEUD below 21 Gy.
