OBJECTIVE To explore the role of clinical pharmacists participating in the standardized perioperative nutritional management process for pancreaticoduodenectomy （PD） on improving postoperative recovery in patients. METHODS The clinical data of 100 patients undergoing PD in the Department of Biliary and Pancreatic Surgery， Drum Tower Hospital Affiliated to Nanjing University School of Medicine from November 2019 to February 2021 were analyzed retrospectively. According to the different perioperative nutrition management plans， they were divided into clinical pharmacist intervention group （n＝51， clinical pharmacists intervened according to the standardized nutrition management process） and control group （n＝49， clinical pharmacists only performed preoperative nutrition evaluation， and clinical physicians took nutrition support according to the patient’s condition）. The differences in postoperative recovery index， economic evaluation index， hospitalization length， postoperative complications， and postoperative enteral nutrition support route were compared between 2 groups. RESULTS The time of postoperative diet， the first postoperative ventilation， the first postoperative defecation， and postoperative drainage time of abdominal drain were significantly earlier in the clinical pharmacist intervention group than in the control group （P＜0.05）； the hospitalization cost， medication cost， nutritional support cost， parenteral nutrition cost， albumin preparation cost， and the length of postoperative hospitalization were significantly lower/shorter in the clinical pharmacist intervention group than in the control group （P＜0.05）； there was no statistically significant difference in the incidence of postoperative complications between the two groups （P＞0.05）； there was statistically significant difference in the perioperative enteral nutrition support pathways between two groups （P＜0.05）. CONCLUSIONS Clinical pharmacists’ participation in perioperative nutritional management for PD can significantly reduce hospitalization costs and nutritional support costs， improve patients’ perioperative nutritional status， and shorten hospital stays. wanglina668@163.com

Objective:To investigate the application of virtual reality (VR) technology on intraoperative pain in patients undergoing peritoneal dialysis (PD)-related procedures with local infiltration anesthesia and the satisfaction.Methods:It was a single-center, prospective, concurrent controlled study. Patients were divided into two groups: VR group and control group. In the VR group, patients wore a VR headset to watch soothing audio and video content during surgery, while the control group underwent routine procedures. Intraoperative pain and satisfaction were assessed using the visual analog scale (VAS) and a 5-point satisfaction scale within 30 minutes of surgery. In addition, tolerance of the VR experience in the VR group was assessed using the VR sickness questionnaire.Results:A total of 43 patients were included in the study, including 25 males (58.1%). Chronic glomerulonephritis [17 cases (39.5%)] and diabetic nephropathy [6 cases (14.0%)] were the main primary diseases. There were 23 cases in the control group and 20 cases in the VR group. There were no significant differences between the two groups in age, sex ratio, proportion of primary disease, diabetes, hypertension, distribution of operation methods, preoperative vital signs and operation time (all P>0.05). VAS pain score was significantly lower in the VR group than that in the control group (5.90±2.38 vs. 7.43±1.67, t=2.469, P=0.018). The percentage of patients who were satisfied was 89.5% (17/19) in the VR group and 78.3% (18/23) in the control group, but there was no significant difference (chi-square test for continuity correction, χ2=0.308, P=0.579). Three patients in the VR group withdrew from the study due to severe discomfort, while the remaining participants found the VR experience to be tolerable. Common adverse effects included fatigue and blurred vision. Conclusions:The application of VR technology in PD-related procedures has been effective in reducing intraoperative pain when combined with local infiltration anesthesia. Furthermore, the utilization of VR technology in PD-related procedures is associated with a safe and tolerable outcome, despite the observation of some adverse effects.

Objective:To evaluate the clinical and ultrasonographic features for early diagnosis and prediction of lateral cervical lymph node metastasis of medullary thyroid microcarcinoma.Methods:From Jan 2010 to Jan 2020 233 patients undergoing primary surgery were categorized as "medullary thyroid microcarcinoma" and "medullary thyroid macrocarcinoma". The preoperative clinical and ultrasonographic characteristics, the diagnostic positive rate of preoperative serum calcitonin and fine needle aspiration (FNA) were investigated between two groups. All patients with medullary thyroid microcarcinoma were divided on the basis of wether there was lateral cervical lymph node metastasis.Results:There were statistically significant differences in initial diagnostic method(χ 2=32.290, P=0.000), TNM staging(χ 2=50.300, P=0.000) between medullary thyroid microcarcinoma and medullary thyroid macrocarcinoma. Medullary thyroid microcarcinoma showed more malignant ultrasonic features. The diagnostic accuracy of preoperative serum calcitonin was higher than FNA for medullary thyroid micro carcinoma(χ 2=47.933, P=0.000). Multivariate regression analysis demonstrated that the abutment/perimeter ≥1/4( OR=25.475, 95%CI: 2.320-279.771), preoperative serum calcitonin >65 ng/L( OR=32.663, 95%CI:2.433-438.409) were the independent factor for lateral cervical lymph node metastases of medullary thyroid microcarcinoma. Conclusions:The combination of ultrasonography and serum calcitonin helps establish early diagnosis of medullary thyroid microcarcinoma. Medullary thyroid microcarcinoma with the abutment/perimeter ≥1/4, serum calcitonin >65 ng/L predicts lateral cervical lymph node metastases.

Objective:To discuss the diagnostic value of superb microvacular imaging (SMI) in renal solid tumors of different sizes.Methods:A total of 142 patients with 146 renal tumors detected by ultrasound in Tianjin Medical University Cancer Institute and Hospital from September 2017 to March 2019 were retrospectively analyzed. The maximum diameter of lesions was 0.8-7.3 cm, and patients were divided into the maximum diameter ≤3.0 cm group (61 patients, 64 lesions) and the maximum diameter >3.0 cm group (61 patients, 82 lesions). All of the tumors were separately evaluated by SMI and color Doppler flow imaging (CDFI) with Adler grade, vascular morphology and peripheral blood flow.Results:In the group with maximum diameter ≤3.0 cm, 50 lesions were malignant and 14 were benign. In the group with maximum diameter >3.0 cm, 62 lesions were malignant and 20 were benign. In the group with maximum diameter ≤3.0 cm, there were no significant differences in location, boundary, echo, homogeneity and small cystic area between malignant tumors and benign tumors ( P>0.05). In the group with maximum diameter >3.0 cm, there were significant differences in echo, homogeneity and small cystic area between malignant tumors and benign tumors ( P<0.05). For all of the benign tumors, there were no significant difference between CDFI and SMI in evaluating Adler grade, vascular morphology and peripheral blood flow ( P>0.05). For malignant tumors with maximum diameter ≤3.0 cm, 43 lesions with Adler grade 2-3 were detected by SMI, which was higher than CDFI (32, P<0.05). There were 38 lesions with dendritic and irregular vascular morphology detected by SMI, which was higher than CDFI (7, P<0.05). The detected rate of peripheral annular or semi-annular blood flow in lesions was 80.0% (40/50), higher than CDFI (18/50, P<0.05). While in malignant tumors with maximum diameter >3 cm, the lesion with peripheral annular or semi-annular blood flow detected by SMI was 38, higher than 22 of CDFI ( P<0.05). The area under the receiver operating characteristic (ROC) curve for CDFI and SMI diagnosis of renal solid tumors with the maximum diameter ≤3.0 cm was 0.627 (sensitivity: 54.0%, specificity: 71.4%) and 0.791 (sensitivity: 94.0%, specificity: 64.3%), respectively, with statistically significant difference ( P=0.039). The area under the ROC curve for CDFI and SMI diagnosis of renal solid tumors with the maximum diameter>3.0 cm was 0.852 (sensitivity: 85.5%, specificity: 85.0%) and 0.860 (sensitivity: 91.9%, specificity: 80.0%), respectively, without statistically significance ( P=0.858). Conclusions:SMI is superior to CDFI in detecting low-velocity blood flow and microvessels in both malignant and benign renal tumors, and can effectively improve the display rate of peripheral blood flow in malignant tumors. Otherwise, SMI can provide better diagnostic efficiency for renal tumors with the maximum diameter ≤3.0 cm.

Objective: To understand the health literacy and relevant factors of cancer prevention consciousness in Chinese urban residents from 2015 to 2017. Methods: A cross-sectional survey was conducted in 16 provinces covered by the Cancer Screening Program in Urban China from 2015 to 2017. A total of 32 257 local residents aged ≥18 years old who could understand the investigation procedure were included in the study by using the cluster sampling method and convenient sampling method. All local residents were categorized into four groups, which contained 15 524 community residents, 8 016 cancer risk assessment/screening population, 2 289 cancer patients and 6 428 occupational population, respectively. The self-designed questionnaire was used to collect the information of demographic characteristics and cancer prevention consciousness focusing on nine common risk factors, including smoking, alcohol, fiber food, food in hot temperature or pickled food, chewing betel nut, helicobacter pylori, moldy food, hepatitis B infection, estrogen, and exercise. The logistic regression model was adopted to identify the influencing factors. Results: The overall health literacy of the cancer prevention consciousness was 77.4% (24 980 participants), with 77.4% (12 018 participants), 79.9% (6 406 participants), 77.2% (1 766 participants) and 74.5% (4 709 participants) in each group (P<0.001). The correct response rates for nine risk factors ranged from 55.2% to 93.0%. The multivariate logistic regression analysis showed that compared with community residents, people with primary school level education or below, and the number of people living together in the family <3, the cancer risk assessment/screening intervention population, cancer patients, those with junior high school level educationor above and the number of people living in the family ≥3 had better health literacy of the cancer prevention consciousness (all P values <0.05). Compared with females, 39 years old and below, government-affiliated institutions or civil servants, from the eastern region, males, older than 40 years, company or enterprise employees, and from the middle or western region had worse health literacy of the cancer prevention consciousness (all P values <0.05). Conclusion The health literacy of the cancer prevention consciousness in Chinese urban residents should be improved. The cancer screening intervention, gender, age, education, occupation, the number of people co-living in the family, and residential region were associated with the health literacy of the cancer prevention consciousness.

Objective: To understand the consciousness of the cancer early detection among urban residents and identify the influencing factors from 2015 to 2017. Methods: A cross-sectional survey was conducted in 16 provinces covered by the Cancer Screening Program in Urban China from 2015 to 2017. A total of 32 257 local residents aged ≥18 years old who could understand the investigation procedure were included in the study by using the cluster sampling method and convenient sampling method. All local residents were categorized into four groups, which contained 15 524 community residents, 8 016 cancer risk assessment/screening population, 2 289 cancer patients and 6 428 occupational population, respectively. Self-designed questionnaires were used to collect population, socioeconomic indicators, self-cancer risk assessment, regular participation in physical examination and other information. The multivariate logistic regression model was used to identify the factors of people who had not regularly participated in the regular physical examination in the past five years. Results: The self-assessment results of 32 357 residents showed that there were 27.54% (8 882) of total study population with self-reported cancer risk, 45.48% (14 671) without cancer risk and 26.98% (8 704) with unclear judgement on their own cancer risk. Among population with cancer risk, 79.84% (7 091) considered physical examination accounted. In the past five years, there were 21 105 (65.43%) residents participated in regular physical examination and 11 148 (34.56%) participated in non-scheduled one, respectively. The multivariate logistic regression analysis showed that compared with unmarried and western region residents, divorced, middle and eastern region residents had a stronger consciousness to participate in the regular physical examination (P<0.05). Compare with residents with annual household income less than 20 000 CNY in 2014, cancer risk assessment/screening intervention population, and self-assessment with cancer risk, residents with annual household income between 20 000 CNY and 59 000 CNY in 2014, occupational population, community residents, cancer patients, self-reported cancer-free risk, and self-assessment with unclear judgement of cancer risk were less likely to participate in the regular physical examination (all P values <0.05). Conclusion From 2015 to 2017, the Chinese urban residents had a acceptable consciousness of the cancer early detection. The marital status, annual household income, population group and self-assessment of cancer risk were related to the consciousness of the cancer early detection of people who had not participated in the regular physical examination in the past five years.

Objective: To understand the consciousness of the cancer early diagnosis among urban residents and identify the related factors from 2015 to 2017. Methods: A cross-sectional survey was conducted in 16 provinces covered by the Cancer Screening Program in Urban China from 2015 to 2017. A total of 32 257 local residents aged ≥18 years old who could understand the investigation procedure were included in the study by using the cluster sampling method and convenient sampling method. All local residents were categorized into four groups, which contained 15 524 community residents, 8 016 cancer risk assessment/screening population, 2 289 cancer patients and 6 428 occupational population, respectively. The general demographic characteristics, the consciousness of the cancer early diagnosis (whether people would have a willingness or encourage their relatives/friends to confirm the abnormal results once which were detected from the physical examination) and other information were collected by using the self-designed questionnaire. The non-conditional logistic regression model was used to identify the relateol factors related to the consciousness of the cancer early diagnosis. Results: As for residents with abnormal result from the physical examination, 89.29% (28 802) of residents would choose to seek medical treatment for further diagnosis. If their relatives/friends had abnormal results from the physical examination, 89.55% (28 886) of residents would encourage their relatives/friends to confirm the diagnosis in time. The non-conditional logistic regression model analysis showed that compared with the public institution staff/civil servants, annual household income less than 20 000 CNY, the western region and the cancer risk assessment/screening intervention population, the company staff, annual household income about 40 000 CNY and more, and the residents from the middle and eastern region had a stronger consciousness to seek further diagnosis; while the unemployed residents and community residents were less likely to seek further diagnosis (P<0.05). Conclusions From 2015 to 2017, the Chinese urban residents had a good consciousness of the cancer early diagnosis. Occupation, annual household income, residential region and population group were related to the consciousness of the cancer early diagnosis.

Objective: To understand the consciousness of the cancer early treatment and its demographic and socioeconomic factors. Methods: A cross-sectional survey was conducted in 16 provinces covered by the Cancer Screening Program in Urban China (CanSPUC) from 2015 to 2017. A total of 32 257 local residents aged ≥18 years old who could understand the investigation procedure were included in the study by using the cluster sampling method and convenient sampling method. All local residents were categorized into four groups, which contained 15 524 community residents, 8 016 cancer risk assessment/screening population, 2 289 cancer patients and 6 428 occupational population, respectively. The questionnaire collected personal information, the consciousness of the cancer early treatment and relevant factors. The Chi square test was used to compare the difference between the consciousness of the cancer early treatment and relevant factors among the four groups. The logistic regression model was used to analyze the influencing factors related to the consciousness of the cancer early treatment. Results: With the assumption of being diagnosed as precancer or cancer, 89.97% of community residents, 91.84% of cancer risk assessment/screening population, 93.00% of cancer patients and 91.52% of occupational population would accept active treatments (P<0.001). If the immediate family members were diagnosed as precancer or cancer, people who would encourage their family members to receive early treatment in the four groups accounted for 91.96%, 91.94%, 92.44% and 91.55%, respectively (P<0.001). The company employees, annual household income with 40 000 yuan and more and other three groups had a relatively better consciousness of the cancer early treatment (P<0.05). Male, widowed, unemployed and from the central and western regions had a relatively worse consciousness of the cancer early treatment (P<0.05). Conclusion Residents in urban China participants had a good consciousness of the cancer early treatment. The marital status, occupation, annual household income and residential regions were major factors related to the consciousness of the cancer early treatment.

Objective: To understand the health literacy of the cancer prevention and treatment among urban residents of China, and explore the related factors. Methods: A cross-sectional survey was conducted in 16 provinces covered by the Cancer Screening Program in Urban China (CanSPUC) from 2015 to 2017. A total of 32 257 local residents aged ≥18 years old who could understand the investigation procedure were included in the study by using the cluster sampling method and convenient sampling method. All local residents were categorized into four groups, which contained 15 524 community residents, 8 016 cancer risk assessment/screening population, 2 289 cancer patients and 6 428 occupational population, respectively. The health literacy of the cancer prevention, early discovery, early diagnosis, early treatment and the demands of cancer prevention and treatment knowledge was analyzed. The level of health literacy among different groups were calculated and compared. The binary logistic regression model was used to analyze the influencing factors of the health literacy of the cancer prevention and treatment. Results: The level of health literacy of the cancer prevention and treatment was 56.97% among all study population; in each group it was 55.01% for community residents, 59.08% for cancer risk assessment/screening population, 61.99% for cancer patients and 57.31% for occupational population, respectively (P<0.001). The level of health literacy of the cancer prevention and treatment of residents aged 50 to 69 years old, other occupational groups, unmarried, the central and western region residents and the group with unclear self-assessment of cancer risk was significantly lower than that of residents younger than 40 years old, personnel of public institutions/civil servants, married, the eastern region residents and the group whose self-assessment without cancer risk (P<0.05) . The level of health literacy of cancer prevention and treatment of females, people who went to high school or over, cancer risk assessment/screening population, cancer patients and occupational population was significantly higher than that of males, people who had an education level of primary school or below and community residents (P<0.05) . Conclusion The health literacy of the cancer prevention and treatment of urban residents in China was relatively high, but there was still room for improvement. Gender, age, educational level, occupation, region, marital status, self-assessment of cancer risk, and type of respondents were the key influencing factors of the health literacy of the cancer prevention and treatment. Male, 50-69 years old, lower educational level, central and western regions, unclear cancer risk self-assessment, and without specific environmental exposure to cancer prevention and treatment knowledge or related risk factors were the characteristics of the key intervention group of the health literacy of the cancer prevention and treatment.
